Welcome to the Crimson Engine. My name is Rubidium. Today we are looking at top-down lighting. It's misunderstood, underused, but in an incredibly versatile way to light your subjects and be able to shoot entire scenes in one take. So top-down lighting is obviously lighting from the top. It gets a really bad rap, mainly because we all know that midday sun is a really terrible time to shoot, because when the sun comes straight down, it gives you these pits, dark pits in the eyes of your actors. It's a very unflattering light. It's harsh, not just harsh as a small source. The sun is very large, but it's very far away. So it gives you very, very sharp shadows. But also the direction of the light coming straight down from on top is really unflattering to most people's faces, and it's something that cinematographers try to avoid. But top-down lighting doesn't have to be like this. There are plenty of scenarios where top-down lighting can be a really valuable tool, can give you a lot of flexibility, a lot of options, and really serve the story. One of the reasons that top-down lighting is so good is that it's a very common way that things are lit in real life. Very often you have a light in the ceiling, comes down or illuminates the ceiling as a big source, and you get that top light, and it does give some really nice shape to the person's face. The problem is that if you have deep, sunk eyes like I do, you don't see the character's eyes. Now that can be a good thing if you're trying to create a sense of mystery, but most of the time we want to connect with the characters we're filming, and so we have to add a secondary eye light in order to balance out top lighting. We have this little gazebo in my driveway. We often eat meals out there, and I look across the table and see the other people, and it's a really fascinating light. It's really sculptural, it's really mystical. I really like the way that people, when they lean away from the center of the light, they fall into darkness, and as they lean forward they're revealed. Now I made a the light coming from the single tungsten bulb in the gazebo, and it was 0.4. So incredibly dark, and because I was filming myself for this test, I needed something like F5-6, so I did what filmmakers often do, which is augment the existing light with another light. I wanted something very diffuse, and so I had to pass it through a softbox with a grid to keep it off the walls, so I had to start with something very bright. Now I got hold of this January powerhouse. It's a 300 watt single chip LED. Very conveniently, it also has a bowens mount built into the body. You're able to get these really affordable softboxes on places like B&H that plug straight into the body of the light, so you don't have to use an umbrella. They come with the diffusion fabric and a grid. They weigh almost nothing, and they're really affordable. So I didn't even use the yoke on the powerhouse. I just hung it from the handle on the existing hook that's in the gazebo. Then I ran the power cable up the side, and I was able to get a really beautiful light. I had it at about 50% power to get my 5.6, and I was even able to drop the ISO to 400, which on the C200 really cleans up the blacks. So you see this first shot I did was just the light itself. Now it's quite soft, it's diffuse, but it really leaves those dark pits in the eyes, which does add a lot of mystery, does add a lot of almost menace. As you see as I lean back and lean forward, it's a great reveal for the character. This was a little too harsh though, so I got a piece of bounce board. It was a 2x3 piece of housing insulation, and just put it on the table in front of me at a slight angle. Now you can see how with this light, the reflection really then fills in those shadows, gives me a beautiful eye light, and really gives you a really cinematic single shot. Now the huge advantage of this is that that one light would work for the entire everybody sitting at the table. You may have to reposition the bounce somewhat, but it means that you could shoot a single take of this entire table going from person to person to person having a conversation and never see a light because the light's above us. Now this is the real power of 360 degree top-down lighting. It means that you can light the whole environment from above, maybe fill with some bounce from the side or from behind camera with a moving bounce, get really tremendous cinematic shots. For this next shot, I shot through the support of the gazebo and I was a little off-center. This gave me a more traditional, far-side key, still top-down and still filled with the bounce, but it meant that there was much more shaping going on because the far side of my face was lit, the near side wasn't, but still with the flexibility of 360 degree top-downs, 300 watts is an incredible amount of power for an LED. It's definitely brighter than the equivalent of a 2k tungsten. It's fully dimmable, it's daylight only, but the advantage of having such a bright light is you can pass it through diffusion and through a grid and still have plenty of punch even to compete with daylight. We could have shot, I could have, we could shoot a scene like this at dusk or twilight, even late afternoon and still have enough punch in the light to overpower the ambient and give a real sense of shape to the characters. Because I went through the trouble of building the softbox, I used it to light this so it's a four and a half foot octa box with diffusion and a grid that's just off to the side here and it's a really nice soft cinematic light as well. I didn't have enough space above me to do top-down lighting with this. It's about three and a half feet deep and my ceiling isn't high enough in the studio. It's another way to use a really bright LED passing through diffusion fabric to give you a really versatile way of lighting and shooting your scenes. That's my look at top-down lighting with the Generate Powerhouse. Thank you very much for watching. Check the description for links, leave the questions in the comments and I will see you next time.


Let's look more closely at the Dirac equation's problem of negative energy solutions. We'll use normal units where the speed of light appears explicitly. The positive energy solutions have a minimum for momentum P equals zero. So the lowest positive energy level is E1 equals MC squared. Higher energy levels correspond to higher momentum, the electron moving faster and faster. And this continues without limit towards E equals infinity. Suppose an electron has energy E2. It can drop to energy E1 with the emission of a photon. If this is the lowest possible energy state, the ground state, then the electron would remain there indefinitely. The negative energy solutions mirror the positive ones. The highest negative energy is minus E1, corresponding to zero momentum and electron at rest. Lower energy states correspond to higher momentum, the electron moving faster and faster. And this continues without limit towards E equals minus infinity. The existence of negative energy states means that an electron with energy E1 can transition to energy minus E1 with the emission of a photon. From there, it may continue falling to ever lower energy states and emitting photons without end. So it seems every electron in existence would fall down this negative energy ladder, emitting an infinite amount of radiation in the process. Thankfully, this doesn't happen, but it makes the Dirac equation as it stands unviable. In 1929, Dirac submitted a workaround of this problem in a paper titled A Theory of Electrons and Protons. In the section subtitled Solution of the Negative Energy Difficulty, after noting the problem, he offered a solution. The Pauli Exclusion Principle, however, will come into play and prevent more than one electron going into any one state. Let us assume there are so many electrons in the world that all the states of negative energy are occupied, except perhaps a few of small velocity. We shall have an infinite number of electrons in negative energy states, and indeed an infinite number per unit volume all over the world, but if their distribution is exactly uniform, we should expect them to be completely unobservable. Only the small departures from the exact uniformity brought about by some of the negative energy states being unoccupied, can we hope to observe. Dirac went on to suggest that these unoccupied negative energy states might actually be protons. So, Dirac says, yes, there are an infinite number of negative energy electron states, but they're all full, and the infinite number of electrons that fill them are invisible. They have no observable effect. It's hard to overstate how woo-woo sounding this idea is. As far as the negative energy states go, it's invisible electrons all the way down. So within any milliliter-sized region of space, there are an infinite number of electrons, with velocities ranging from zero to arbitrarily close to the speed of light. Yet we can't see them, or otherwise observe any effect due to their presence. This explanation became known as the Dirac C. Needless to say, it was controversial, and was the target of serious criticism. In the opinion of Werner Heisenberg, quote, the saddest chapter of modern physics is and remains the Dirac theory. I regard it as learned trash, which no one can take seriously. Here's the thing about science, though. Ultimately, people's opinions don't matter.  There is only one scientific authority, and that's nature. What matters is if an idea leads to testable predictions, and if those predictions can be verified. Dirac supposed that just as negative energy electrons could emit photons, they could also absorb them. Therefore, a photon of energy 2mc squared could cause an electron to transition from the highest negative energy state to the lowest positive energy state. Half of that energy, mc squared, would correspond to the mass m of the electron. The other mc squared would also correspond to a mass m. Moreover, taking a negative charge away from nothing would leave a positive charge behind. Dirac called this empty negative energy state a hole and predicted it would behave like a particle with the electron's mass and opposite charge. Here's a cartoon representation of this prediction. The electrons in the box represent the invisible Dirac C. On the left, a photon excites one of the Dirac C electrons into a positive energy state wherein it becomes visible. This leaves a hole in the Dirac C. The energy of the system has increased by 2mc squared. The electric charge has not changed because we've merely changed the state of a pre-existing electron. Dirac's claim, shown at right, is that this will appear the same as if we created two particles with positive energy, an electron and a positively charged particle with the same mass as the electron, which for now will call a positive electron. The energy of this system has also increased by 2mc squared and the charge has unchanged since we've created both negative and positive charges, which cancel out. At left, suppose the electron above the hole moves downward. In effect, the hole has moved upward. At right, this would be equivalent to the positive electron moving upward. As this continues, what we would observe is a positive electron moving through space. In 1931, Dirac submitted his prediction for publication. He claimed, A hole, if there were one, would be a new kind of particle, unknown to experimental physics, having the same mass and opposite charge to an electron. We may call such a particle an anti-electron. And there you have the prediction of antimatter. There was no experimental evidence for the existence of such a bizarre thing. This was motivated solely, one might say, by Dirac wanting to fix a seeming shortcoming of his equation. He continued, We should not expect to find any of them in nature on account of their rapid rate of recombination with electrons. But if they could be produced experimentally in high vacuum, they would be quite stable and amenable to observation. So, according to Dirac, it should be possible for the energy of a photon to be transformed into an electron-anti-electron pair. The electron and anti-electron can be distinguished by applying a magnetic field, which causes moving charges of different signs to curve in opposite directions. In 1932, Carl Anderson was using a so-called cloud chamber to observe cosmic rays. A charged particle traveling through a cloud chamber ionizes molecules along its path. Those ions then cause a super-saturated vapor in the chamber to condense into a visible cloud of droplets. The result is to make the particles track through the chamber visible. Anderson observed an event of the type predicted by Dirac, confirming the existence of the anti-electron, what we now call a positron. Here's a later result that shows the process more clearly. At the point marked by the arrow, we see two particles diverge. They curve in different directions in the magnetic field, allowing us to identify the upper particle as a positron and the lower particle as an electron. At the time Anderson published his result, people were using different names for this particle, including the anti-electron, the positive electron, and simply the positive. Anderson suggested the name positron, which is stuck. He also suggested that by symmetry the electron be called the negatron, a name that didn't stick. So, in spite of the bizarre woo-woo nature of the Dirac-C concept, Dirac and his equation were vindicated. The main weakness of his theory became one of its greatest strengths. Still, there's something strange about this Dirac-C idea. In the cartoon at left, we need the Dirac-C as a place to first pull an electron out of and second, as something for the whole to exist and move in. This is what the Dirac equation predicts. To tune it right, there's no need for a Dirac-C. We simply create an electron-positron pair. This is what is experimentally observed. Isn't this a more elegant explanation? It doesn't require space to be filled with an infinite number of invisible negative energy electrons. So why can't the theory predict that directly? The problem is with quantum mechanics itself. First, we started with the assumption that psi is the wave function of a single electron. There's nowhere for other particles to fit in the theory. Second, in both the Schrodinger and Dirac equations, the probability at any time that the electron is somewhere in space is always 100%. Therefore, projecting this back in time, it can never have been created. And projecting it into the future, it can never be destroyed. It follows that if an electron appears, it must have already existed and merely transitioned from an invisible state to a visible state. And, if it disappears, it must have merely transitioned to an invisible state in which it still exists. The Dirac-C provides the required invisible state and it provides a way to account for the properties of a positron as a whole in the Dirac-C in a theory that only describes electrons. What in time became clear is that, to quote Stephen Weinberg, relativistic wave mechanics in the sense of a relativistic quantum theory of a fixed number of particles is an impossibility. Another theoretical framework was needed in which to express these ideas. Eventually, quantum electrodynamics, the first quantum field theory, was able to recast the Dirac equation into a formalism that gives a rigorous and coherent description of electrons, positrons, photons, and their interactions without negative energies and without the Dirac-C.


When Plato described Atlantis beyond the pillars of Hercules, we should remember the fact that this region was vastly unexplored and such a thing called the edge of the world still existed. According to Greek mythology adopted by the Etruscans and Romans, when Hercules had to perform 12 laborers, one of them was to fetch the cattle of Graeon of the far west and bring them to Eurythrius. This marked the westward extent of his travels. A lost passage of Pindar was the earliest traceable reference in this context. The pillars, which Pindar calls the Gates of Gaddus, when he asserts that they are the farthest most limits reached by Heracles. Since there has been a one-to-one association between Heracles and Malkart since Herodotus, the pillars of Malkart in the temple near Gadiria have sometimes been considered to be the true pillars of Hercules. According to Plato's account, the lost realm of Atlantis was situated beyond the pillars of Hercules, in effect placing it in the realm of the unknown. Beyond Gaddus, several important Mauritania colonies in modern-day Morocco were founded by the Phoenicians. As the Phoenician merchant navy pushed through the pillars of Hercules and began constructing a series of bases along the Atlantic coast, starting with Lexus in the north, then Chalea, and finally Magador. Mauritania is the Latin name for an area in the ancient Magrib. It stretched from central present-day Algeria, westward to the Atlantic, covering northern Morocco and southward to the Atlas Mountains. Its native inhabitants, semi-nomadic pastoralists of Berber ancestral stock, were known to the Romans as the Mari. Beginning in 27 BC, the kings of Mauritania became Roman vassals until about 44 AD when the area was annexed to Rome and divided into two provinces. This area is, of course, where the Eye of the Sahara is located, which fits Plato's description of Atlantis. Is that just a coincidence you have to wonder? Search for Atlantis is human obsession. There is a little-known expedition in ancient times to find this land, which was in this unknown realm, and the explorer who went in search goes by the name of Hanno, the Navigator. Wait, do you hear this? In around 500 BC, a major journey was undertaken by the Carthaginian explorer and navigator Hanno. The epic voyage took him through the Strait of Trebralter and down the Atlantic coast of Africa. This was a voyage into the unknown and the idea at the time was to find the fabled mighty empire of Atlantis and set up trading routes. We know of this journey through a complete set of inscribed tablets describing Hanno's effort to seek out the riches which were on display at the Temple of Baal. The expedition became even in antiquity, one of the most celebrated voyages of discovery ever undertaken. It was an epic effort. The first-hand account of Hanno's voyage survived through antiquity and into the modern age via a single medieval manuscript. Itself a copy of a Greek translation made from the Punic original which was carved on a dedicatory stela 400 BC. Scholars consider there to be at least two missing parts of the surviving text, including the conclusion. The work titled simply The Periplis or Coastal Voyage is short, but such is the posity of Punic literature which survives. It is inevitable far beyond its subject matter of seafaring and exploration. The original surviving manuscript is part of the codex Palantines-Goracus 398 and resides in the University of Heidelberg Library. Hanno is referred to in the text by the Greek term Basilis, which is almost certainly a translation of the Punic Sufit. The highest administrative role in the Carthaginian government, often translated as Magistrate. His name is a common one in the powerful Carthaginian clan, the Magnids, and would suggest he was a member of it. Beyond this, we have no other information about the leader of the expedition. The Roman historian Justin mentions in passing that Hanno fought a war with the Mauritanian natives in the mid 5th century BC. Given that Hanno's expedition established colonies in this area, Morocco, and would probably have caused competition with local tribes, this may well be the same person. Other ancient sources which refer to the expedition include Herodotus in the 5th century BC, Paleophantus in the 4th century BC, and various later Roman writers such as Pliny the Elder and Arian who likely consulted a 1st century work by Juba II of Mauritania titled The Wandering of Hanno. The precise state of the voyage is not stated, but was probably undertaken sometime between the late 6th century BC. The Carthaginian ships were made from wood and had a single sail with the possibility of ore power if necessary. They did not have the compass and so relied on the stars, especially Ursa Minor for navigation. The following is a brief piece of the text of Hanno's epic voyage. This is the story of the long voyage of Hanno king of the Carthaginians into Libyan lands beyond the pillars of Hercules, which he dedicated on a tablet in the temple of Cronus. The Carthaginians decided that Hanno should sail beyond the pillars of Hercules and found cities of Livy Phoenicians. He set sail with 60 Pentecounters and about 30,000 men and women and provisions and other necessaries. After sailing beyond the pillars for two days we found the first city which we called Thymaterian, Tangier. Sailing thence westward we came to Sullaes, a Libyan promontory covered with trees. There we found that a temple to Poseidon. Journeying eastward for half a day we reached a lake not far from the sea, covered with a great growth of tall reeds. Where elephants and many other wild animals fed, a day's journey beyond this lake we found cities on the coast. Passing on from there we came to a large river, Lexos, the draw in Morocco, flowing from Libya. Beside which nomads called Lexotai pastured their flocks. We stayed some time with them and became friends. Inland from there dwelt inhospitable Ethiopians in a land ridden with wild beasts and hemmed in by great mountains. They say the Lexos flows down from there and that among these mountains troglodytes of strange appearance dwell, who according to the Lexotai can run more swiftly than horses. Taking interpreters from the Lexotai we sailed south along the desert Sahara shore for two days and then for one day eastward and found a small island five status in circumference at the farther end of a gulf. Made a settlement there and called it Cerna. We judged from our journey that it was directly opposite Carthage for the voyage from Carthage to the Pillars and from there to Cerna seemed alike. We sailed on for five days along the coast until we came to a great bay which our interpreters called the Horn of the West. In it was a large island and in the island a saltwater lake within which was another island where we disembarked. By day we could see nothing but a forest but by night we saw many fires burning and we heard the sound of flutes and a beating of cymbals and drums and a great den of voices. Fear came upon us and the soothsayers made us leave the island. The Greek translation of Hanno's text has taken some liberties with names and there are geographical inaccuracies. The historian S. Moscati plausibly suggests that they may have been deliberately included to prevent unwanted competitors muscling in on Carthaginian trade relations. The final part of the journey is debated amongst historians. Some suggest Hanno reached only Sierra Leone, others that he went as far south as the Cameroons or Gavin. Even the shorter journey which some prefer because Hanno would have struggled in the time to reach further south would still have involved an outbound leg of almost 3,000 miles. The fact that Carthaginians sailed down the west coast of Africa is cooperated by Herodotus and by the fact that the whole expedition was to found colonies strongly suggesting that the Carthaginians had visited the coast previously in order to ascertain it was worthwhile sending Hanno's large fleet. Other Carthaginians travelers soon followed and exploited the newfound sources of gold the bartering for which is described by Herodotus. Another famous traveler, the Greek Polybius, followed in the wake of Hanno and sailed down the same Atlantic coastline in the 2nd century BC. For whatever reason though, significant further exploration of the African coast and interior would have to wait another thousand years. It is a curious story and we would love to know what you guys think of this account. Comments below and as always thank you for watching.


Again. So welcome everyone to our first meeting of 2022 for your DLF's Museums cohort. So we're just a heads up that we're recording today's meeting and it'll be shared on clear DLF's YouTube channel so keeping video on or off is completely up to you just wanted to give everyone a heads up. I've shared it in the chat but the agendas and meeting notes document for the year are at bit.ly slash DLF Museums 2022 instead of a nice Google link we've I've learned. So, if you haven't already in the shared notes, add your name your institution pronouns, and just you know whether you're new or returning attendee of the cohort today. So if you aren't familiar with the shared note stock we encourage meeting attendees to take collaborative notes and therefore reference later either for folks who attended the meeting if there's any links notes etc you want to make sure you remember later, or for anyone who won't be able to attend person who will be watching the meeting later. It's nice to be able to have some notes from the meeting to refer to so feel free to jot down any any relevant information in there. Oh, and I apologize, I don't know if I introduced Gail Schachter I'm the program associate for DLF. So just really super briefly just because these slides are linked to in the meeting notes and any links to stuff that you want to find out more about the cohort are available, right in the slides there, but just really brief for anyone new or people who are a little less familiar with the museum's cohort. So the cohort has been around since 2015. It was started basically as an exclusive group of DLF members museum members of DLF with support from the Samuel H. Kress Foundation. In 2018 with some additional support from Kress we opened a call for new members to the cohort and expanded with an additional 14 institutions joining up that year. Again this was still just, you know, a smaller, you know, smallish group, and it was just open to staff and those working at those museums. So in 2019. The cohort opened up to basically anyone with museum interests to just put it very broadly. We sort of like DLF's working groups we wanted to make sure that it was open to all regardless of whether you are affiliated with one of our members or not it's just you know, open access open, open equitable things that's what we're about here at DLF so, and actually 2019 in the fall is when I started working for clear and took over the cohort from the previous DLF staff member back of Kwan, who sort of started up the cohort originally with the member museums. Um, so now we're at 2022. Two years into, you know, pandemic and over the past couple years since I've been working with DLF we've had continued to have monthly meetings of the cohort and we've had some really great people come to us and talk about a really nice wide variety of topics and just generally a nice sort of gathering place to fill a need for the community, because there's this sort of overlap of museums folks, you know, museum library folks with digital library and archives practitioners and there's a lot of, you know, gray area and overlap in a lot of the institutions particularly smaller ones so we wanted to just, you know, we're sort of a gathering point for all these folks. So the plan for 2022 is just because due to constraints on staff time. We are going to DLF staff, I myself will be organizing as opposed to monthly meetings in 2022 we're going to do one a quarter and you'll see on the share notes the dates of all the meetings for outside of, you know, a meeting for the DLF forum which is sort of in the works to brainstorm about, but in terms of meetings you can attend that are not at a conference that you have to register for will have four meetings this year. Today, April, July and October. I would say that we won't return to a monthly meeting format in the future just for right now. DLF is taking some time to figure out what are some future directions for museums cohort because it's a little, even though it's open to participation like all of our working groups it's sort of a little bit different and so we, we want to remain remain a dedicated for the community and I'll in the next slide I'll explain some of the ways we will do that. But we wanted to sort of as a program really look into what are some potential next steps for museums cohort so it's very much in the infancy of planning right now so as we have updates we will of course share them with the group. And, you know, it's sort of a, you know, if you have thoughts on the cohort you're always welcome to get in touch with us as well where we're trying to keep thing the lines of communication open that way. Sort of in, you know, to elaborate a little bit on what our plans are for this year so we'll have the staff organized calls once a quarter. However, if community members I you or you know anyone else who's involved with the cohort has a topic or, you know, anything where you would like to organize a meeting of the group and that could be on our standard we stand we typically had our last Wednesday of every month so if you want to have a meeting at that time like an, you know, sort of regular museums cohort call, you can schedule then if you want to schedule it at any time that is more convenient for you if that was if those Wednesdays afternoons don't work. We're happy to give you the same kind of support that we give to all our working groups in that you can schedule these calls on our zoom account by getting in touch with me. And, you know, if you need help promoting any initiatives that you're working on related to the cohort or any meetings you're planning to hold. We're happy to be at your disposal in terms of support in that regard so you know we're always happy to support you all sort of if you have something that you want to take the lead on in terms of whether it's meetings or, you know, putting together a project under the cohort. We're always happy to have a limit there so we're always happy to have a discussion with you on that. Outside of meetings we also have our lists serve and again there's links to this I have links to the stuff in the slides and this document that you can grab later. And if you're not already subscribed to our dedicated museums cohort lists serve, I definitely encourage you just to subscribe there. That's where all of the announcements related to the cohort get posted, as well as any kind of, you know, occasionally job postings will be in there, if folks are working on something and they have a question to pose. Outside of our normal meeting schedule. That's another great place to ask it it's really just meant there to be a space for the community to raise these issues that maybe other lists or forums aren't really the, you know, or in addition to. And as I mentioned, DLF staff are always happy to discuss your ideas for the cohort, including even if it's not. Something like you organizing a meeting on your own if you have someone you want us to get in touch with to see if they're interested in speaking or any kind of topics you want the cohort to discover, then that's kind of. And, you know, we're again, it's really, there's no set rules to things so any ideas we're open to. So these are sort of the ways to stay in touch with the museum's cohort if you're tweeting about us the hashtag is DLF museums. Obviously viewing these you won't. These are all linked to just download the slides for meeting notes. And also just have the link to that in the chat again for you again if you are joining us a little later and don't have the link to today's meeting notes. So if you want to just sort of overview of the group itself the history of the group, the various, you know, link to our listserv. If you have any other relevant group links like our shared drive, you can click on the link to the group overview on DLF website discussion list pretty self explanatory. As I mentioned, this meeting is being recorded and not all past meetings but several of our past meetings from the past couple years have been recorded the presentations and are available on clear DLF YouTube channel. So please feel free to watch those at your leisure and then as always you can contact DLF staff at info at didgelib.org. So in terms of the rest of the meeting. I would like to sort of leave things open to the group for, you know, questions just talking about you know, any thoughts you have on the group writ large anything covered on the survey that we put out in November at the DLF forum. So sort of with that survey got a good idea of the types of topics the group is interested in and we're sort of using that to guide our internal planning for the group and again I don't have a ton of updates in terms of the plans but again as we discuss with those and we have a better idea of how things will take shape with the group. Later in the year and beyond. We will, of course, get the word out to you all. And then I think I haven't mentioned in the. Let me stop sharing my screen so I can see our notes again. All right, there we go. So let me. I can see everything. So yeah so our next meeting, and I mean I'm jumping ahead a little bit but just to get, let you all know the next meeting that we'll have as a group as is in April 27 and we're sort of jointly hosting that meeting with our list. And it is museum library division and the topic is going to be digital preservation to small to medium for small to medium sized institutions which that topic as a whole was one of the more popular choices from the survey we put out. And there's certainly a lot of interest and desire for more knowledge of that in the community so we're, you know, checking checking around to see who will be able to have presented that and hope to have, well obviously have an announcement for April but again just make sure you're subscribed to the listserv for any updates on future museums and then as for our museums in July and October we don't have a set agenda or topic for those meetings yet so if you have any thoughts on those or something that you want to bring to the info at digital.org feel free to email me for that one as well so now that you've heard my whole speech for today that's kind of it from me I kind of want to just if folks are new and you have questions about anything with the cohort now would be a great time to I'm more than happy to address those or if anyone who's returning cohort member has anything to throw in please do or if there's any thoughts related to the survey itself or any of the sort of topics therein that this group covers happy to talk about them now. But yeah, I'll just sort of stop talking leave it to the group now if anyone, you can either put it in the chat or or on Mike either one is whichever works for you. I mean, I just wanted to express gratitude to DLF for having the inclusive spirit that surrounds this group, I've, and thank you to you for hosting this small off camera. I'm gathering today I kind of feel like that might be symptomatic of, at least where where I'm at as an institution which is, which is, I'm sorry I'm not an institution but where my institution is at which is that it's, we're so small, and we're so stretched right now in just trying to carry on basic functions that to me this cohort is just kind of a welcome nudge periodically and quarterly is great monthly I fully appreciate that that might be up to up to members to provide the evidence for some of that. But that's, that's just kind of where I'm at I don't know if others are in a similar boat right now but I just wanted to give voice to that, maybe, and the upcoming the April calls sounds like a fantastic topic and a discussion that I would like to be part of. If I can manage the time then. So that's it. I don't trust if I wasn't hosting the meeting today I would have my camera off as well. But, and that's the thing that you know, especially in terms of pulling back a little bit from monthly meetings and sort of evaluating what may be a good direction for the cohort we're very aware of the fact that people are very fatigued and I mean even you know personally when I have groups outside of work asking me for stuff I'm very, very selective with my time because we're all I think we're all sort of in varying degrees of burnt out. And so, yeah, we wanted, you know, we wanted to make sure this was carrying on, and not sort of abandoned just because, you know, oh we don't have time to do a monthly meeting for everyone so we figured this would be a good, a good way to sustain this group of people taking the time to get to really focus on what will work for this cohort because I think for the past couple of years I've been trying, or yeah, I've basically been trying to turn this into more of a standard DLF working you know just like you can't really fit a square peg in a round hole so you know something about the nature of this group. It's a really special and important, you know, area and place for folks to come together on these on the topics relevant to our membership but you can't sort of force volunteerism on people so so that's why we're sort of you know we're looking into what would make sense opportunity wise for the group and you know whether that's looking into funding for stuff or etc again you know it's all very in the infancy of planning but we're always happy to support not just museums cohort but the wider DLF community in any kind of initiatives you want to take on you know our working groups are generally or you know all sort of just a lot of them just spring up out of conversations at DLF forum people like oh we should we should address this and you know that's all of a sudden you know they just hit the ground running so that's why you know we're always sort of like the door is always open so to speak to have a conversation with us if you have ideas about anything so I always want to make sure that I'm sort of you know really really sending that point home to folks that were we're always happy to listen to you all. Yeah, so I'll you know anyone else feel free to just interrupt me. I will just add obviously our April meeting we're focusing on the digital preservation talk but we do recognize that there's other needs and interests in the community so it's we're not planning to have all of our meetings this year focused on that and yeah I just wanted to reassure anyone if you thought like it's just going to be a digital preservation year for museums cohort that's one thing we're doing but it's obviously not the only thing. And yeah and there's also some overlap. And if you ever need resources from our other working groups again feel free to contact your staff, but we have a few different groups that have documentation that while not necessarily aimed for our museum specifically there you know could be useful guidance in there. I'm thinking of stuff like our foreign digital access working group. We also have our digital pedagogy group if you're looking for more teaching resources there's I'm like I work with working group all the time then all of a sudden I'm like wait what are all the working groups. So you can always go to digital.org slash groups to find out more about what our groups are doing so I always want to make sure that you all know that those resources are there as well. So beyond that any questions about the group any thoughts about, especially looking ahead to our July and October meetings which I know seem far away but it's already almost February. So any thoughts about topics you'd really like to get in front of my eyes and make sure we try and maybe explore at one of those meetings. And if you can't think of something now that's fine you can always add it to the meeting notes later, or email us. But yeah chat is totally fine for questions or comments as well. I wanted to make sure it's giving folks enough time to type in the chat if they needed to but don't see anything coming in yet. But otherwise, yeah if folks are a little tapped out for the day I get that. So you know we can definitely end things a little early and give you back maybe half hour of your day. I will stick around in the room I'll stop the recording and stick around in the room for a little bit if anyone wanted to chat about something off camera real quick, but otherwise. If you're coming and, as always feel free to email us anytime with any questions about anything and looking forward to see you all in April, if not sooner. But yeah, thank you and have a good day.


I made this video in December 2021. I have been doing mission boards since I was maybe 16 or 17. I am doing one for 2022. I just like to have boards that remind me about my goals throughout the year. And like I said in the video, I like to have attainable goals and then goals that seem so ridiculous or sometimes seem so attainable to me. And then at the end of the year, I'm like, wow, you really thought you were going to be able to do that? I'm not too confident about the bigger goals, but maybe some of the smaller goals, I've accomplished a few things. I wanted to look back at my goals being that we only have like three more months of this year to see what I still need to achieve. I'm pretty confident in that I need to change my goals. So you've might have seen this vision board that I have up there behind a lot of my videos. So I'm definitely going to update it by next vlog. Let's watch the part of the video where I talk about my action goals and see where we are. So for my acting career, I want to take a Meisner acting class. I really love that technique. So no Meisner class this year for a lot of reasons. I would love to take a workshop like a Meisner workshop, an improv workshop and a commercial acting. And I want to get a theatrical LA agent by March 1st of 2021. No, that did not happen. I have been searching and searching for an agent and I did submit to quite a few. But the thing is that I'm trying to submit to a certain level of agents that I think maybe aren't like wanting to get me because I don't have that many credits. I want to change this to by December 31st, 2022. Three referrals to agents by people in the industry, like an acting coach or a casting director or something like that. Somebody in the industry, not a referral from another actor. I'm confident at least one person right now that could refer me to an agent in LA. So I'm going to keep that. I still need two more professional referrals, but I definitely have one in mind. I want to be in a TV, in a film that requires skating. I'm not good enough yet at skating. I don't believe, but I am skating every day. As of filming this video, I have been skating for 14 days in a row and I've been going to rhythm skate classes. So I am confident that I will be a much better dancer in like a rhythm skater in like a month or so. What I'm going to do is add to create a skating reel in September so that I can have a reel and show people what I can do so far. On my casting websites. And then as I get better, like in October, I'll make one November and then that way maybe I'll be a lot better by December and I can actually get cast in something or a skate. And then I also want to be in a film or TV show that requires for me to speak Spanish. I did do a commercial for Covered California earlier this year. In Spanish, so I did that. I would love though to do something theatrical, but it's not absolutely necessary. Like we only have three months, you know? Like if something in Spanish comes up, cool. If not, next year. And I want to produce three shorts. Oh, I forgot honestly that I put produce three short films. What I meant by that, I should have been a little bit more specific, but what I meant by that was like create three short films where I acted. I do still want to do two more after this. The one we're working on currently, we did a crowdfunding campaign. We have $10,000 to do it, but the other two, I just want to do them low-key. Like I just want to like get them done. And something else I want to add is I want to get cast in a Christmas something. Every year I audition for a Christmas thing. And I would love to be in a Christmas commercial, a Christmas short, whatever. The other two shorts that I wanted to produce this year as my goal, one of them's going to be skating and the other one's going to be Christmas. That way if nobody cast me, I cast me. And then three co-star roles hasn't happened. And I do feel that I need an agent in LA to be able to get me more opportunities because this year I've auditioned for one co-star role so far. So that goes hand in hand, I believe with the agent one. I'm going to leave that there. Miracles can happen and also I'm very enthusiastic about goals. Look up different shows and different people that I like their work and put their names on my vision board because I want to work with them. Okay, I've definitely been doing that. I have been doing a lot of industry research and I do have a spreadsheet with show runners that I like their shows and I want to work with in the future. I want to book 20 jobs and make $70,000 after taxes in 2022 total.  I've booked five jobs and I am nowhere close to $70,000 after taxes. Let's just have $70,000 after taxes. That would be nice. Earned from YouTube, acting, day jobs, anything. Oh, and that's all. Those are all my acting related goals. I also have YouTube goals, basically like have fun and make more money off of YouTube because I like it and how cool would it be if I made more money from YouTube? Well, you know what? It's okay. I don't feel like a complete failure because I do feel like this year more than ever. I've really been taking advantage of the time and the resources that I have and working really hard to make sure that I am always working and focused like this actor routine that I've had, I don't know for like a couple of months now, has really helped me to get better at acting and practice acting consistently and do YouTube and share information and make connections. So I feel really proud of myself regardless of if I end up doing all of these goals. But I am going to update my vision board and I'll show it to you guys next Saturday, next week's vlog. Let's see what we can do. If you're a casting director, if you're a creative in LA or in the South Bay, in the San Francisco Bay area, let me know, maybe we can do something together. I'm interested in first gen Latinx stories, skating stories, Christmas stories. That all sounds really fun to me. Go ahead and just leave a comment and then we can connect and see if it'll be good to work together. Probably not with everybody, but we'll all find somebody to work with.  Let's talk. But we need to do our actor check-in. If you've never seen one of my Saturday vlogs, I like to use you guys as accountability buddies in my comments on Saturdays to make sure that we're all on track. Work on acting stuff throughout the week and then check in. Devin, Julian, Patty, Henry, you guys are some of the people that have commented before what you did this week. So let me know in the pinned comment what you did to level up your acting or just something that you incorporated this week in your habits. Some of my habits are memorizing scene study industry slash agent research and I've added skating and then this week I added gratitude as well. So I did really good, you guys. So I memorized five times this week. I did scene study slash was a reader four times, which was mostly scene study because I had to do the yetus abes and castability. And then I did industry research slash agent research three times this week and I skated eight times this week and I did gratitude five times. I was just feeling down and I thought maybe looking at my goals would be fun to reorient. We still have three months left. Like that's a decent amount of time. It's going to go by really fast because I am traveling and then the holidays and camping. But it's all fun things. I'm really excited and enthusiastic. I'm so happy right now. Thank you guys so much for watching my videos, especially if you're over here at the end of the video. Oh my gosh, there's like nobody here right now. Demon cheese mitt. I hope you guys submitted to the yetus abes monologue slam if you're Latinx over 18, if not in the future. If not, there's more opportunities for all kinds of people. I have tons of videos on how to find auditions and open casting calls and stuff like that. So you guys can check those out here and at the end of every video I feature another channel. Who am I featuring today? I'm going to feature Dav again, active poet. You guys, he's so talented. He needs to go viral. Like this song, I keep talking about close friends but it's a really good song. So go check him out if you want.


I was at this conference last year and I overheard somebody ask a vendor at their booth if their tool excluded weekends from lead time metrics. And I asked him, why do you want to exclude weekends? And he said, my team doesn't work weekends. I don't want that to count against us. I said, how is it that lead time metrics count against you? He said, it's in my goals, it's on my performance review. I think this is a big problem and I said so on Twitter and people came back and said I want to hear more about it, so here I am. There are three main reasons why I believe excluding weekends or any time people aren't thought to be working from metrics is a bad idea. Reason number one is that all you have to do to discredit a metric is to question the assumption. Let me demonstrate. So are you saying you never work any weekends? What about holidays? Should we go with US holidays or UK holidays? Should we look at all the vacation days people actually take or the ones that they qualify for? What if we just took the actual hours that people worked? I jumped ahead. What about sick days? Anybody work when they're sick? What if we just took the time that people actually worked? Let's just look at lead time and hours. Does everybody always work a 40-hour work week? How much time are we willing to spend debating assumptions so that we can make our metrics credible? Reason number two, lead time exclusions encourage is gaming of the data. What happens when resource utilization decisions are made based off of time sheets? How accurate are those estimates? I've seen people attribute 100% of their time to one single project because they thought I would otherwise reflect poorly on them. That data was wrong and what sources that everybody knew it. When people work weekends but don't count that time, the metrics can be deceptively reassuring. Isidore Duncan says that we only see two things in people. The stuff that we want to see and the stuff that they're willing to show us. And if people are concerned about or they're unable to reveal, they don't want to reveal things to us. We lose transparency. There's no transparency in that. Using metrics to shame people encourages gaming and same thing with target driven metrics. When the focus is on the metric itself instead of not the goal, we've got a problem. Reason number three is that business customers, they care about duration. If you're my customer and you ask me how long it's going to take for that feature to be delivered and I tell you 30 days from now, you're not going to be happy if 30 days from now you discover that it's another 11 days because weekends and holidays don't matter. That's not going to fly. In my experience, I haven't heard customers care about how long it took in dev or test. They want to know about the duration. Lead time is a measure of duration. It has a start time and an end time. That's all. Lead time doesn't do start, stop, start, stop, start, stop. That's going to be wait time and work time and wait time. What lead time does do for us, what lead time does do for us is it quantifies the probability of completing X percent of work in so many days. And that's what allows us to be more predictable. That's what allows us to say, look, 95 percent of our work can be done in 15 days or less. So there's always going to be variability in our system due to whatever, unplanned work, holidays, sick days. Let's credit leadership for understanding that a request coming in on a day before a three-day weekend is going to have a longer lead time. They'll be more appreciative of the accuracy. The visibility of accurate metrics is what helps us make good decisions, but it totally depends on the transparency of others. So let's help people be okay with truth. If you want more predictability in your organization, then make your metrics credible. And that means including weekends. Thank you.


Minnesota officials are scrambling to assemble a plan that would help offset major health care premium increases for next year. Governor Mark Dayton unveiled a rough plan Thursday that would use money meant for the state's budget reserve to buy down an average rate hike of 55%. After several plans exited the individual market, Minnesota residents are faced with some of the largest premium increases in the nation for plans ushered in by the Affordable Care Act. The Minnesota Legislative Republicans held an emergency town hall in Bemidji tonight to discuss the problem. Josh Peterson has more. Finding a quick fix for Minsher is a hot topic not only at the state capitol but all over the state. Tonight Republican legislators and candidates hosted an emergency town hall meeting in Bemidji to discuss the rising cost of health care as well as hear concerns from the public. I have a number of my constituents that have sent me emails with premiums above $30,000 a year projected $30,000 a year. Questions from the public ranged from what to do about losing a health care insurance provider as well as emotional personal testimony. But it was the public's call to legislators to put partisanship aside and work together. I'm just asking you to consider do the work of the people for the people. That's all. For some that attended the town hall they have chose not to purchase health care and just take the penalty because of the growing issues with the health care system. So for me it just doesn't make sense. I think the one problem that I've really run into is the fact that they will penalize you for not having it. When Republicans were asked about the governor's proposal to use $300 million of the state surplus to pay for rebates the Republicans appreciate the help but they say it's not a complete fix. And I appreciate that he wants to do something to help but that it can't be just that because one year from now he will go up the rest of that plus whatever rate it is. With the clock ticking and open enrollment beginning at 12.01 a.m. on November 1st legislators know they have their work cut out for them. It truly is affecting all of Minnesota so it's our pledge here that we will roll up our sleeves and do our best but I won't say it's going to be easy, it's going to be hard. In Bemidji I'm Josh Peterson, Lakeland News. People with questions are urged to call Minshure before open enrollment starts next week. You can find help online or call 1-8-5-3-M-N-S-U-R-E.

Hello everyone this is financial author Amit Dan of AmitDan.com on this channel you'll find financial travel and more videos just like the one you're watching right now. If you like what you see please give me the thumbs up and consider subscribing. Hello everyone this is AmitDan of AmitDan.com. Today I'll have another episode of unboxing and brief review video and today I'll be presenting a Sony mirrorless camera. The model number is Sony Alpha 5100 and I'll just first go over some specs which is on the package and then now I'll do the unboxing and then later on I'll attach some pictures and video clips to give you an example of how good or bad are these clips and pictures and how is the camera. Start with the specs first so just take a look on the package so this is EPZ 16 to 50 millimeter aperture is 3.5 to 5.6 OSS this is the lens kit which comes with the camera and let's take a look at some other features here so the file format is XAVC which is Sony's format and then we have AVCHD another format and the camera shoots in Dolby digital stereo and it has HDMI port and looks like for a still image it can take 4k photos however for video it only does 1080p and let me just take a look here if there's something else here okay so there's some more information here so this is Wi-Fi certified DLNA and NFC compatible and it has fast hybrid autofocus and LCD monitor which is a touch sensitive it comes with a built-in flash and the picture is 24.3 megapixel and the sensor is ABS-C size sensor and let's just take a look here this is part of the Sony E-mount camera so any lenses which are part of E-mount lenses will be able to fit into this camera however it does come with a lens kit which is the basic 30 16 to 50 millimeter aperture 3.5 to 5.6 OSS lens okay so let's start with unboxing so okay so I have some looks like brochure and manuals or guarantee card whatever they are so this looks like a small brochure booklet which is right here and this is in French here for now let's take out the camera okay so this is what looks like inside the box and let's see what's in here okay so I have the battery here I'll just put it in here battery model number mbfw50 so just put it in here and that looks like we have a attachment cable or attachment hook which is good to hang on to the shoulder so it comes with this camera which is a good thing to have I'll just put it in here now and then we have that adapter which is right here this kind of looks like my other sony cam adapter which I'm using the which is the cam I'm using right now to shoot this video and then there is the usb cable and it's a micro usb cable to charge the camera could be to data transfer okay so looks like we are left with only the camera here there's nothing else there's a section here which is empty so there's nothing in here so let's take out the camera okay so now we have a totally empty box I'll just set the box here and it's wrapped in a packaging and just we'll put it away and just take away this one okay so here is the sony f5100 attached to its lens kit and this is right here and here is the back of the camera and here is the operation buttons and there's the key clip to attach the card to hang on to the shoulder and then on this side you have a standard 3.5 slot for tripod or or selfie stick kind of thing and then here's the touch lens so the camera is very lightweight it's not heavy and it's a very compact and it looks like this is lighter and smaller than canon g5x which I was going to buy before I came into conclusion to buy this one let me just take a open the flip cover and then once you have the cover up then you can see yourself which is a good vlogging camera and that's my main reason to buy it and at this point I do not have any idea or I do not know anything about the operation or other stuff of this camera so what I'll do I'll do a I'll charge the battery so here actually here's the front top portion of the camera and there should be a flush somewhere which should be popped out okay I guess it looks like I think I need power for that and it doesn't have power right now okay so I'll just charge the battery and I'll go through some settings and do some video and take some pictures and then I'll attach it to the unboxing video so we'll have a look of everything all together so just give me a few minutes and I'll attach this with this video thank you hello everyone this is image stabilization testing I'm using the sony a 5100 mic and you will be able to see both how the mic works and how the image is stabilized stabilization as I'm walking while talking with this camera and this is the real mic and it will give you an example of how a stabilize is the image of this camera hello this is image stabilization testing and real audio testing of sony a 5100 so whatever you're hearing is just coming through the camera's real mic and you show the webdick to see how the image stabilization works


at the Emergent Earth Tent, I'm hugely grateful to Claudia and to Igor and to MCH for providing this platform for talking about the impact of internet and technology and hackers to the environmental sustainability and our earth. The overarching topic for my talk today is communities. So how can we join up in our efforts to contribute to the solution of our problem without being too doomsaying and pessimistic. And the most concrete thing that I want to talk about is a conference that I attended called Computing Within Limits. Oh yeah also I'm going to be lisping because I got bitten by a wasp yesterday in my tongue so it's it's it's I'm lucky that I can speak at all. So the the conference itself was an academic interdisciplinary event that actually has been happening since 2015 and this was the eighth edition also because they were disrupted by by the pandemic and I haven't been there in person ever but I've been following them closely since 2018. So this year it was a virtual event and the connection between that conference and the hackers community is that they have been talking about the topics that we have been also covering here at MCH but also there is a third community that I want to talk about which is the RIPE community because I work for the RIPE NCC as a community builder and the RIPE community also has a big overlap with both the hackers community and the academic researchers. So I'm going to come to this like from kind of three angles and since we don't have here slides or anything all the links you can find at RIPE labs which is labs.tripe.net. I have published the article there going through some of the papers that have been presented at the conference but we also have a section about sustainability and the other articles for example about how is the the flooding that consequence of the both climate change and sea level rise going to impact the data centers. So how can the data center industry prepare for the future of the two centigrade higher average global temperatures. So computing within limits yeah it's a nice conference let me just read about the conference from their own words. So as an interdisciplinary group of researchers practitioners and scholars seeking to reshape the computing research agenda grounded by an awareness that contemporary computing research is intertwined with ecological limits in general and climate and climate justice related limits in particular. 2022 submissions moved us closer towards computing system that support diverse human and non-human life forms within thriving biospheres. So that sounded wonderful like before it started and then there were great great great papers presented and also the format was super weird. They have published all the papers in advance so then the presentations were limited to ten minutes which is very short for academics and so they so there were like three three papers presented at every session so that would be like half an hour and then there was one hour discussion session in breakout groups called reverse panel. So the authors would publish some questions like what did they want audience to comment on and then the participants would have discussions between themselves and write their feedback in the collaboratively edited documents unfortunately Google docs but still so everything was published public and transparent and open and the participation was also for free so it was really nice group exercise in like really interdisciplinary you had people from social sciences, the computer science, the artificial intelligence, the activists, the artists so it was really really nice. So some of the papers that I found interesting for example strategies for degrowth computing so that's combining this concept economic concept alternative economic concept of degrowth with the research into the new development of hardware and software and how can we actually do that by sticking to the physical limits by extending the life of computers increasing the intensity of use and what what else did they say hardware repurposing software design for the lowered power requirements and so on so that actually ties up with your talk and the discussion that we had yesterday and it also like all so many talks there have mentioned something called Javons paradox which is about the how the increase in efficiency actually only leads to the increase of demand so it doesn't like the increase in efficiency which is supposed to then keep the expenditure lower doesn't happen because the more things you provide like they often give example of highways because it's just more tangible for people to kind of understand what's happening like the more highways you build it's not going to lead to less congestion or the traffic is just going to produce more traffic because people will just start using cars more and they'll be like more cars produced and people will want to move further away and more frequent and so on so the same is with the with the internet efficiency so here we are unpredictable weather patterns everybody's helping to rescue the papers and clothes from the rain I'm your reporter now if you're watching this on stream or even on the recording thank you for saving all the papers okay we go on so the next work was about calculating the carbon footprint of streaming media now this is a super controversial topic because the researchers don't agree on how can you calculate the energy expenditure of the streaming media and so the authors propose the holistic end-to-end model that balances the high level and highly detailed approach and so shit everything is getting wet so they have published that watching one hour of Netflix consumes about one kilowatt of energy which is equivalent to a passenger vehicle driving about two kilometers so now you know when you're binging on Netflix what does it mean I'm sure this conclusion will be disputed in the next versions of the of the computing within limits conference but their slides were amazing because so their paper paper is really worth downloading and looking into especially if you're interested in this because they have compared the previous research like over the many years many people are trying to calculate this and they all disagree with each other and so actually there is an upcoming conference called ACM SIGCOM in Amsterdam at the end of August and we have organized a workshop there called Building Greener Internet so one of the papers submitted to that is called 13 propositions for something like that like saving the world with green tech or whatever but that is already pre-published so it's amazing by posing all kinds of questions related to this topic so yeah I'm sure it's going to dispute this paper so the next one also very dear to my heart conceptualizing resource aware higher education digital infrastructure which is basically criticizing the fact that all the universities have outsourced their infrastructure like operating their mail servers and the document sharing or everything to unnamed huge providers of the cloud services which I don't want to promote here like let's say big five and the authors are suggesting alternative strategies for self-hosting which is kind of returned to how self hosting and and yeah super weird that we went away from that so I will read it because it's really beautiful a first quantification of a potential return to self-hosting emphasizing its effect in energy reduction and avoiding e-waste then policy actions are needed that could enable higher education institution to retake control over their digital infrastructure by building local services so this kind of ties to so many different aspects of like avoiding centralization and so on so this this mode of operation reduces waste and has the added benefit of increased resiliency to scenarios of resource scarcity and collapse of external infrastructure the architecture of a low impact data centers made upcycled hardware and resource aware software there is a significant space to reduce digital infrastructure overall resource footprint so they are proving that it's actually it's like the opposite of this claim that if you put everything in a huge data center that is more energy efficient they're saying it's not it's actually better to maintain these services locally not only for the energy efficiency but also for the resilience for the climate catastrophes like flooding and fires and we could see that like there were outages recently of the huge data centers because of the heat wave and also because of just nothing related to climate but like human mistakes like the the Canadian monopoly telco went down for several hours and it took down all the services around Canada because they all had their eggs in the same basket so emergency services were down of course mobile phones and they couldn't even publish like warning to their users that they are down because they were down and there was no alternative so yeah this this like what I just said happened after the conference so it just really proves the point that the resilience is in decentralization then there was an interesting more like a social scientist artistic paper called the richness of designing for eco social change so they they were suggesting to reframe limits to abundance of the resources that are naturally not limited like human connections human creativity and care and so this is really like intersectional feminist approach to the concepts of limits in computing so they they called it like this a fusion of care infused ecological and social sensibilities to create existential change that would impact lifestyle and political choices and technologies turning to potentially abundant human resources of imagination reflection and solidarity their example was of a hologram a feminist economies healthcare art project situated online illustrating this potential so they have been suggesting this project at so many places where events that there was a conference in Amsterdam called money labs they were suggesting this as alternative economic project they're actually presented to the hope conference when it was online in 2020 and now here at the computing within limits so I want to connect this to the like the mental health crisis that also came like to focus during the pandemic and their approach is super simple so they illustrated with like a tetra whatever pyramid or something in Greek where you have like four points one is you and three is other three of your friends and you form a certain hologram kind of a hologram and you each one of your friends has like responsibility for one aspect of your well-being and they don't have to be experts they're just your regular normal people friends and so one of them is focused on your physical man well-being the other one on your mental well-being and a third one on your social economical well-being and you meet periodically and you have a discussion about you so they go like how are you doing and then they and then they say oh yeah last last month or over last six months I see that this is happening and then you covered those three aspects and then you have a discussion like what would be good for you and that's it so it can be done in person it can be done online it can be once a week or once a month or once a year depending on what your needs are and that way you don't depend on the health providers which are also depleted and on the classical economy like you really just do this together as a community and then you expand so it's not like once then you do that for other constellations or for people groups so that's what they call hologram okay next one oh yeah I have a question have you read or seen any of those computing within limits conferences papers before just cloudy so it's super cool go check it out the link is on this behind this link it's called computing within limits together like computing within limits no if you just go to labs the trap net it's like one of the first articles if you scroll down it's called computing within limits 2022 event rap yeah so all of their papers available line I won't talk about more of them anymore I just wanted to mention these other opportunities for like combining this with other communities so as I said I'm from the ripe community and working for the ripe NCC and we have many events where you could take part and also working groups where this is relevant the ripe community functions as like a voluntary participation of mostly network operators but also other people who are interested in the global internet governance on mostly very technical level but we have been seeing over the time that the internet is not for techies and by techies only anymore so we are including more and more people in in our own community and we are of course overlapping with many different communities so if you have interest in this you can take part in different ways like in for example Internet of Things working group or something that we call cooperation working group where we cover more soft topics and like legal political social topics because normally we would only talk about BGP routing DNS IPv6 security even security is like top layers like and content is completely out of the question but actually it's not so it's kind of creeping in with with the censorship with the shutdowns and so on so these topics of sustainability have also been covered but it's really not enough focus on them so I want to invite you to take part and you can do that online we have mailing lists we are also all over different social media but we don't have like a specific channel where I can invite you to there is Telegram there's Twitter there is Facebook and Discord and stuff like that and then we have a meeting in October in Belgrade like it's a large conference there is a call for presentations open normally you would have to pay the conference fee to participate even if your speaker just like here but we also have a lot of programs that help people who cannot afford to pay several hundred euros for like three 400 euros for a week of a conference so we have academic cooperation program where the academic gets sponsored to come and take part and we also have a fellowship program where anybody can apply and then we choose who do we want to to bring there so those are the ways that you can take part in the RIPE community and then there is CCC coming up in December where we will probably meet again and they had included a lot of these topics either in the regular program when they called the conference resource exhaustion some years ago or they have a parallel like a separate conference called bits and trees in German which I will not try to pronounce Boime bits and Boime and that's happening at the beginning of October in Berlin maybe I'll have a talk I applied I didn't hear yet if it will be accepted but there will be parts of this community also there so for me the events like these regular points where we can meet up and synchronize what we are working on and for the rest there is the mailing list that I'm on together with Claudia and Igor and many other people that we kind of started in 2013 after the home conference where I for the first time got exposed to these topics and it's called uncivilization and so you can you can find the link also like deep deep deep down because following this link because it's not work related but I will write it down here anyway so it's unsafe.nl it's a personal project the website is maintained by my partner and it just leads to a wiki where there's a lot of links and and also the mailing list and squirrels so my obsession with squirrels also started by that time because I was thinking like if this what we're doing to the to the planet leads to the collapse of human society fair enough we brought it onto ourselves but what's not okay is that we bring the squirrels with us so we really I invite you to consider the squirrels when making your political and technical decisions and more concretely you can take a squirrel candy now just an illustration that was at the CCC camp also where the squirrel actually was working against the technology like revenge of the squirrels yeah okay so yeah now we have time for like discussion and your contribution are we stopping with this streaming or we continue with this I'm not saying until two o'clock that's too much yes yes thank you what do you say as a streamer because I participate at one conference there but it was not for me it was not clear what for instance you said that it was only people from academics but it was not really clear what was the you know the goal of something it was really very everywhere you you involved some organizing the limits of computing conference so I'm not involved in organizing it but they do know a lot of people who are and the the program committee is really mostly academics from a lot of different universities and it goes around it's hosted by different universities and so they try to make it as multidisciplinary as possible but still it's very how can I say like it's hard for the people who are not academics to even suggest the paper because you have to write it in that format like so even if they are artists and activists like like this project of hologram they have to kind of pair up with somebody who knows how to submit that kind of format of paper which which is okay ish like you have to work in in different groups like in a group that has multiple kind of skill sets but it does make it difficult to to join so this is one of the problems that I see across many communities they so focused on their own jargon and that there is so much translation needed between different approaches like this is academic approach and so if I would invite them to the right meeting they would be like well why should I talk to the network operators how can I talk to the network operators and the other way around if somebody from the network operators would want to submit the work here it's just so difficult to translate our way of speaking to so that's why we try to organize a join meet a workshop at the next academic conference this SIGCOM and then you have to pay a ticket like for one day workshop it's a lot of money for people who are not really getting anything out of it the same for the right meeting like when we invite speakers from outside of our community there is so many obstacles there well the same for MCH like some people found it very expensive so there is economic aspect of why this crossover is not happening so there is economic blockages the jargon and yeah yes yeah so that's why it's important to have these crossovers and to tell people like but you could take part there and the very important factor that is now making things much easier is that we are moving online so that's both like you you don't have to be there physically you don't have to travel you don't have to pay you can just use zoom for the limits for MCH for ripe like for everything like if you can't afford to go there physically either because you don't have money you don't have time you have small kids that you have to take care of you you can still participate so this is great on the other hand it's it's great to some extent because what is the cost of doing the double conference doing it in person and actually streaming everything we don't know what the cost is we think it's actually not too bad but but we don't know because partially because it's hard to calculate and partially because we don't want to know because then would do we have to cut it out like do we not meet in person or do we not stream it and yeah it's it's really hard but I think I think people would be more comfortable if you know for sure what the cost is of your action that you could act on on your cost so that's this kind of things what I expected also from the limits of computing and you know I didn't know anything about it and I wanted the conference that was a conference and I was like puzzles and and because I really expected something very practical in this way it is practical that they do have a paper published on like you know one hour of streaming doesn't matter if it's Netflix or this costs like driving a car for two kilometers so some people would but then is it individual or not like does it take hundred people does it does the cost decrease if just one person is watching the stream or there's thousand people watching the stream is it still thousand times two kilometers or is it divided by thousand people and what is the cost of storing it so that other thousand people can see it five years from now in the data center which has to then run 24 seven so that maybe on an off-chain somebody is going to want to watch this video and if I have to say like don't store this because I don't want to kill the squirrels because somebody might want to watch me on a video five years from now does it matter like does it like does it is it going to switch off the the data center for five minutes so that my video won't be stored there it's it and it's not about personal cost I think it's really about the systemic yeah but to to to access at a personal level when you do something you want to know you know what's the what's what's my you know ecologic footprint here in this action and would really help on a lot of things also to to to allow people to make decisions I think that it is part of denial that that that we enjoy I personally also enjoy because and somebody else in some other presentation said recently like one of the oh it was elvin one of the answers is like but we need more measurements no we don't we know it's too much we don't know how much how much too much it is but it's definitely too much and and and then the then the follow-up action would be but let's not do it but I don't want to say that because I enjoy too much it's also like I was reading a paper about like the mechanisms emotional mechanisms towards for emotions towards climate change one of the most used to mechanism seems to be so well I don't know if I say well that you minimize your cost but the thing is like everything you know you you're leaving it's it's it's too much so we have to make like a more informed choice but with less parallel paralysis because this causes paralysis but if you if you can choose you know no only more you know you don't have to read very very well as specific as possible but you you know it leaves you some emotional space to make good decisions yeah okay I'd like to pass the mic to other people yes I really I would like to have the name of the paper that you mentioned about that self-hosting is more efficient because I have been told that yeah no people should go to the cloud and it's also more green and I've been teaching people that because people explain it to me like yeah you share the resources and I thought that sounds nice but so I was also wondering maybe if you could elaborate a little bit more now or someone else if they have more information about it so this specific paper is called conceptualizing resource aware higher education digital infrastructure it's a very long title but you can find it back through through this link and or just computing within limits the main author is L and jelly so you can look it up that way and of course it is controversial like that they probably had their own favorite outcome and they did the research towards that on the other hand it's not only about economic like energy efficiency but it's there are other elements in like why the self-hosting is better than outsourcing everything to the cloud so they probably took those things into account and and what I like about it is the ethical aspects which is avoiding the consolidation towards few actors avoiding the loss of autonomy and not delegating your sustainability choices to a third party so that's that's worth something too even if the energy efficiency aspects are questionable but I think they also mentioned because they are academics they mentioned other papers within their paper so then you can look like look it up cross-reference and like choose your own bits to confirm your own decisions because yeah that is the beauty and and the tragedy of all this like academic research like there is so much knowledge and so much information that proves anything and then we still have to choose anybody else no I want to finish on a nice note let me see how oh yeah no well let me talk about some more interesting ones so there was something about solar protocol exploring energy-centered design and then an interesting one called smart enough or too smart about smart cities so like that's very IOT yeah within the IOT topics and but of course they brought it up with the intersectionality to a different aspect which is saying how all these smart devices actually replace or aiming to replace the emotional labor so they call that social reproduction so how does this technological solution actually impact the areas in our life that that do not have to be governed by the internet of things or things at all so and then they also mentioned the concept of digital circuits circuits of dispossession so what does it take away from us leaving the decision-making to algorithms and things so yeah I'm having goosebumps it's really like science fiction material but then in reality oh yeah and a very very cool project or paper about that I thought would fit in the MCH so well it was called omni food exploring the possibilities of a consumer system with obi ubiquitous access to data about the food we eat so making choices based on the artificial intelligence machine learning things and stuff about what you eat by so they did it in Sweden and they they had several methods of getting to that goal which is intercepting the data between your hand held scanner and the computer that like produces your bill like how much you have to pay for for the things you bought by also printing the ecological footprint information about every item with color coding and like looking it up in the databases which are open and just saying like well this avocado traveled from Brazil to Sweden or this meat has been grown locally so it is meat so that's like really bad but at least it didn't travel from whatever like Holland and so that that's one way and then the other way was when you order things online and then it like shows you you know what you're going to buy and stuff and then it also shows you like this is the ecological footprint yeah impact yeah where I live that is ecological supermarkets that's labeling the foods on the real price of the foods you buy which is very cool yeah so so there is there is work to be done in this area but it is also a lot of I'm sorry else I'll swear in Dutch me renoken because it's like you don't really have to know how expensive that meat is it's just too expensive like on the planet like so the same like what I'm saying like with the technology like we say we need more measurements but actually we know the answer but we just don't like it you know it's also kind of I think it's a kind of shaming people also but it works you know I don't know everything that works it's I really welcome you know if you buy something they say well okay you buying feel ashamed to buy something that's gonna destroy everything you like no yeah like Tesla okay let me let me read some of these slides because it's actually hard but just to end on a like more tech related so how to do the degrowth computing extend the useful lives of computers reuse instead of recycling reuse as energy storage like information batteries and make out Tarkic systems whatever that means you can you can look up like the details there then use computers more extensively so share the unused time broadly define computers so like consider all the things that actually have computing power in them but we don't really think of them as computers but they actually are and then use all the other tips for that and create the low-powered standardized smaller footprint devices and then the third was the growth design so consider these degrowth in the software engineering use the flexible computing with the view of intermittent energy so if you have the like renewable energy sources they do not give consistent energy so design for that in the design stage and then use the open design and the right to repair and the use the degrowth for the hardware engineering so not don't wait until you actually have a hardware that can do certain things and then try tweaking software for it but use the engineering of hardware with the degrowth in mind from the beginning but a lot of these are kind of contradictory because that would mean designing new hardware but the first one was reuse the existing hardware so they have to be considered in the balance of what what is available and what your goal is so this is where I want to end and thank you very much for participation and thanks thanks a lot for your insights and we have also wiki it's emergent.earth so you can I'm going to to add all the information that what all what happened here but you'll of course it's a wiki you can also you know contribute to the wiki thank you
