The anatomy of a coin might seem pretty simple. It's a small circular piece of metal with two sides, but there's more to it than that. Okay, let's start with the obvious, the two sides. Those are referred to as the obverse and the reverse. The obverse is the head side or the front of the coin, so you'll usually see the portrait of a monarch or leader of some kind. Coins are a great way to assert the power and influence of the nation's leader, in fact, they still are today. The reverse is the tail side, which often shows cloaks of arms or more pictorial design. In modern coins, they can feature all manner of subjects from Paddington Bear to Olympic sports to flamingos. Legend or motto is pretty straightforward. That's the text seen on the coin, often across the top of the reverse. Then there's a value also called the denomination. Country and the year of issue. The rim is the raised edge or circumference of the coin's reverse or obverse, which can often be beaded. It's not to be confused with the edge, which is the bit around the outside. The edge of the coin can be smooth, rich or grooved, and in more modern coins can also feature text. Take the £2 coin, for example, which has the Isaac Newton quote standing on the shoulders of giants around the edge. Incidentally, Oasis guitarist Noel Gallagher saw the inscription on the £2 coin and decided to name the band's next album after it, though he accidentally left off the airs, so it was the only one shoulder. But back to the coins. A few other terms include relief, that's when the coin is raised, so the side of the coin isn't completely flat. Mint mark, there's often a very small letter in the design, especially on US coins, which refers to the mint where the coin was produced. You might also see the designer's initials on certain coins, sometimes referred to as the signature. The field, that's the flat part of the coin design. So that's the anatomy of a coin, simple stuff, but the differences in all these elements can influence scarcity and the value of a coin, and they all come together to create that beautifully designed piece of history in your pocket, or stored safely in your coin cabinet.


Kia ora. So my name is Renee Shalu. I come from the traditional unceded territories of the Musqueam, the Squamish, and the Selwattooth nations, otherwise known as Vancouver. Sometimes I call it Auckland North. So a little bit about the city, just for context, if you don't know about it. So Vancouver, it is actually a lot like Auckland. It's a maritime seaside city. It's been inhabited though for over 8,000 years by our host nations. The white people showed up in about the 1800s to cut down all the trees and drop all the animals. And now it's a pretty big city, a lot of IT, a lot of tourism. We're at about 630 population at the last census with 250 identifying as immigrants and 15,000 as indigenous persons. So we've got quite the diversity thing going on. A lot of different languages, different alphabets. Let's see if I can make this work. No, this is fine. Okay. And this is just hit this? Yeah, just hit there. There we go. So I work at the public library. These are a couple of our branches. We're a 23 branch system. We have our flagship downtown branch. Can you see there? Okay. It didn't move. There we go. Okay. So Vancouver Public Library, fancy building in the middle. We've been around for over 100 years in our various locations around the city. We have a lot of active card holders. So you could see our numbers here. We've got over 269,000 regular card holders, a lot of uses of our spaces and our collections, both digital and physical. I work in our systems or our, sorry, our digital services department. So it's our organizational chart. And that's me with the ponytail in the middle. And it actually looks startlingly like me. And I actually have a green kayak that I sit in a lot. Anyways, so we've got three portfolios. We've got our digital collections. So ebooks, the databases, et cetera, et cetera. We've got our web folks, our UX, and they manage our Drupal website. And in the middle, community digital initiatives, what is it? We're not sure, but it's from a strat plan created about five years ago, based around some reports around social isolation and people feeling like they're not part of their community. Like I said, a lot of newcomers, not just from outside the country, but inside the country as well. So we were mandated to use, collect stories to use as ways of connecting people, of different backgrounds, different places in their lives. So we started up with a couple of oral history projects. The first one was about the West End, and it was a hundredth anniversary of one of the high schools down there, secondary schools. And then after that, another small project on Chinatown. And we also did something that was really interesting, is digitizing a quilt. And quilts, it's a series of banners that were handmade to commemorate the missing and murdered Indigenous women in Vancouver. And it's carried in a commemorative parade every year. So that's actually a really at-risk physical object that we took high-resolution photos on. We collected some stories about the women themselves, put them up there. So if you've got a computer or a phone, you can have a look at it. So you can see that we're the smallest of the three teams. So we've got some challenges trying to get these projects going. So that's our team. So we've got an assistant manager that was me temporarily. I'm back to being the librarian one, yay. And we've got a library technician. And we've got our graphic artist who has made our site so gorgeous. So this Vancouver is our repository platform. We use Islandora, which is a Drupal fedora, kind of dearly. But we really made it look a lot different than normal Islandora sites, which have tended to be institutional repositories. We really went for look and feel. And actually, one of our hopefully future community partners described it as, oh, it doesn't look like a website. It looked like community. And, you know, I kind of did a little of the cheering up thing.  And each separate collection has a separate tile. So you could see this isn't the whole deal, but we put a couple of other pieces of content in there mostly just to sow the seeds when we only had a few projects opening up. So Story City, you could see there it is up at the top and about the project. So Story City was part of Canada 150 plus, which was a happy birthday to us. The plus was to acknowledge that there were other people there first, and we want them to be involved in the celebrations. So sorry to get my notes down here. I've got them really, really big. So I don't have to wear my glasses. Here we go. Okay, so we got a fairly large chunk of money from the feds. They were flinging it about. And we spent some of it on extra staff because you saw we have a pretty small team. And we spent some on recording equipment. And we were mandated to go out there and collect a whole lot of stories, at least 150 from all over the city and try to be as diverse as in your inclusion of different communities and voices as you can. And then to present them in a mapping format to be able for our users to be able to explore with a sort of geographic entryway. So these are our pillars and our scope for our project. So we want to collect people's stories about journeys to Vancouver, the evolution of Vancouver's neighborhoods, and personal stories as a way to explore the interwoven, ongoing journeys and experiences that come together to make up the fabric of the city and then to focus on our First Nations, our host nations, but there's also quite a few indigenous folks who've come from other places in North America. So diversity and inclusion. So we worked for months on on collecting these interviews. We went to community festivals. We had in library special recording sessions. We had out library special recording sessions. I went to church for the first time in about 20 years. Nothing bad happened. So at the end of all that, we had over 360 individual interviews. And that's with a team of four working. So hooray for us. We launched in October. And what we had done is we'd cut up those interviews into small manageable bite-sized pieces. We tried to stick with the scope of the project and go for as wide a variety of topics and people as possible. But we really did go for the inclusion of people. So with the exception of seven interviews, I think, each of those 360-ish people had something included. So that ended up with over 700 separate objects or excerpts from interviews. So we ingested them into Islandora, into this Vancouver. And the mapping module that was created for us, we just had to add geographic coding for it to appear on the map. Okay. So we finished by October, even though the birthday actually happened in July. And so there was quite a bit of fanfare. We got some media attention. Our marketing department was really behind us. We got posters. We got social media. And then we had an event that was fairly well attended at the Central Library. We got our favorite people. And they came down and told stories. And it was quite crowded. And people really seemed to enjoy themselves. And we got a lot of use at the beginning. There needs to be a better way to do this. So at the beginning, we got a fair amount of usage. And if you look at our page views, if you could see that, we're looking at since we launched over 11,000 page views. So it's not horrible. But the problem is things fell off fairly quickly. We generated a lot of interest and then that interest waned. That was our bad. But so a couple of people I've spoken to already today were like, oh, you're doing fail stories. I like those. So hopefully we all like fail stories. So I mean, there are amazing things about this project, just the experience of doing it, talking to people, the skills that we built, the connections that we built, the map elements of it are fantastic. But yeah. Anyways, a lot of the problems came after the fact where we just left it alone. We didn't. There was not care and feeding. So why is that? So common organizational elements, I'm sure many of us are familiar with them. So we had a lot of staff movement. And when you consider how small our team is, one person leaving that team makes a huge difference. We had two. One has since come back. Hooray for him. As of last week, I was like, yes. Second part is these are pretty unique skills. So we have a pretty shallow bench. So if somebody leaves or has other projects to work on trying to get somebody in to do some of this work, who can do it, right? I'm not saying I do it particularly well, but I know how to do it. So I don't know. Is there an appropriate rugby metaphor to talk about a shallow bench? Okay. We'll stick with baseball. I was hoping for hockey, but whatever. And then there's the problem of the new things coming along. So we know this meme, right? This translates down here? Okay. I just want to make sure. So here are projects that we've worked on on to and we're really lucky that we live work in a really great corporate culture that allows us to innovate. So we're on to virtual reality stuff. You can talk to me about that later if you want. There's some really cool stuff we're doing. We had a live exhibit in the library when we opened up the new spaces on levels eight and nine are top floors. We created this beautiful public space for programming and exhibits, and we got drafted onto that team. Again, great experience, but took up all our time for a really long time. So our collections are going, excuse me, and we just kind of left them out there thinking we have done well and people will look at them. Well, of course, we're wrong. We saw the numbers. So here's the problem is innovation at the expense of maintenance. So this is something that's hanging above my desk right now. It's been making the rounds on Twitter. So how much are we hurting ourselves or missing out by failing to appreciate the value of maintenance at the expense of innovation? We love to innovate. We love because it lets us learn and expect it allows us to improve ourselves. But if we don't take care of what we have, then that's a problem. So what should we have been doing in the meantime or at least trying to make time for in the meantime when we're working on each other's on all these other projects? So maintenance, yeah, but the second part is really, really important and you can't maintain unless you engage because engagement is maintenance. It is checking in with your stakeholders who are your users and it's user testing and it's user collection assessment.  And it guides you in your future. So how you treat your current collections and your new collections. I'm just checking my time. I'm probably going to have to skip a few things. But anyway, so situation right now we're in is we're redeveloping our site. We were given a room to be able to get a development environment set up for the first time for our team to learn Island Dora and be able to fix some problems with it. Our solar doesn't work properly. And if you can't search, yeah, you can't work, you can't search properly. You know, no filters, no faceting. Just don't even get me started. The map isn't searchable. It's a little bit of a problem. So we're looking at that. But it's also the time to just step back and look at those collections and think about them and think about, okay, what happens in the new platform? Do we treat everything the same or do we treat it differently? Another thing that has happened in the meantime, though, is we are in talks with a group called ARCA to actually migrate to them off of our own servers and they maintain Island Dora. And this came not that long ago. So now it's like an extra thing where we're actually possibly moving right out of the joint and then upgrading to Island Dora 8. So suddenly all of these things are happening. And we have no idea where we're going. So that's kind of putting us in a position of, uh-oh. So looking at the collections, and that's one of the things I've been really tasked at. And I will let you know, because of these things that have happened with the redevelopment and the migration, not even close to where I thought I would be by the time I got here when I sent my proposal, I thought we'd actually have a bit of a plan. No. But as a librarian, one of the first things we think of when you are maintaining your collection is. And, you know, to some people that's very frightening. I know there's different corporate cultures around retention and whether or not you should take things out of your collection or not. So do I have to explain this meme? Okay, somebody didn't know what it was last night. I might have mocked them. So, you know, I'm a public librarian, have been for 20 years. I'm a voracious reader. I throw out so many books. It's frightening to some people. So, yay. Then there are. This is my interpretation of archives and museums have that mandate of preservation and retention that public libraries just don't. So moving on. I'm still a librarian. I understand that there are a lot of risks associated with with these unique digital objects, these heritage, possibly heritage objects that are essentially irreplaceable. But yeah, I'm a librarian. There are reasons to weed, not the least of which of my boss telling me to. But you want your collection to be precise, tight, interesting, engaging. Chris this morning, he articulated it very well around, we gave them less to see or lessen the page and saw more. So even with search and other ways to explore, you can have too many things on your page. And we have too many things on our page. It was Story City for sure. So 700 things, even with even though the map scrolls really nicely. Again, it's not searchable. So weeding. Yeah, so there's risks with it, beware. In this case, the emotional factor, this is actually ours. I know there are librarians out there who are emotional about weeding books, I mock them. And now it's coming home to roost. We are the creators here. So we feel ownership because we, you know, we were the audio recorders and producers, but we also spoke to these people. We sat down at tables with them, we shared coffee, we share tea. And it would actually hurt to kind of get rid of their stuff. So there's also the community factor. Could be problems. Somebody comes back looking at Story City and not finding their interview, their Annie's interview. Bad community relationships. So best practices for weeding digital heritage collections. Yeah. We're making them right now. A lot of people in this room are making them right now. And it is a cross-sector thing. So we all, we're all coming from different directions. So I'm going to skip that. But if anybody doesn't know Seema Rao, she's really good, but she's talking about maintenance and sharing about maintenance. Talking just about retention criteria. I am getting close to my time. I'm going to skip some of this stuff. But there is stuff around judging your material for quality enduring value to local history and heritage. But who says? So for books, we are relying on professional, you know, professional reviewers for stuff like this. But who does it in this case? Who says? So this is a nice statement. I'll make these available, of course, about democratization of digital collections. Talk about, just want to mention usage. We don't know how people are using this because the metrics gathering tools for this mapping module aren't what they should be. So that's going to be at the top of our list when we improve everything. Because, oh, sorry, I'm one behind. Yeah, so usage. Your practice is only good as your yardstick for assessing your collection use. So Google Analytics does some stuff in Islandora Analytics does some stuff. We're really having trouble getting some meaning out of that. So I'm scooting through this. Some things that we learned from a later project called What Changes You can have look at that. But the biggest lessons are scope your projects. Bigger is not better. We had that 150 person, you know, cap and we're so scared of not reaching it that we ran right by it and didn't say stop. Just stop. We were a lot more curatorial with what changes you. We only included the things we really thought popped. So that makes things a lot easier for maintenance. You don't have to make those judgments after the fact. Going back to platform. So collection is only good as your platform. So just lessons learned with that map module. We would have been a lot more, I think, demanding if we knew some of the stuff around not being able to search and what happens when we try to measure usage. So up shots. We cannot properly envision how to treat our collection until we solve some of these problems. So around curatorial exhibition possibilities with the platform, your analytics and public input. So I want to get a rating and commenting feature in Islandora 8. We've got an Islandora developer in the room. So we can actually get, you know, on the spot judgments about the stuff by the people who are using it. Doing some information gathering, literature searches, cross-sector conversations. How's my time? Am I fine? Okay. So where we are is right. So this is what we're doing. I'm doing some information gathering. I'm doing literature searches. I'm contacting. Some of you may have gotten emails from me directly. I will be following up with you because I'm not getting responses to find out how these types of collections are being treated across various organizations and do a cross-sectoral comparison, but that instinct to weed and instinct to keep. And then this is starting to form the beginnings of a policy best practices statement. And as we get more information, we will be solidifying that. And we're actually going to review that statement after two or three years. We're also doing some collection assessment right now. I have a lovely young woman, Chloe, who is grading all 700 and whatever objects are in there based on a point system and then making notes. She sent me an email this morning just saying how hard it is, but it's actually less hard for her than it is for us because she wasn't part of the team and that was intentional. Chloe's actually an auxiliary and I brought her in specifically so that it wasn't our decision. Anyways, something else we're doing is we took some of those stories for repackaging and to regenerate interest and are putting them out as an e-book this week. It's very exciting. We took some of the real tiered jerkers and hopefully that will bring some users back into our collection and we can start engaging with them again. So that's the catalog record. I'm very proud of it. Look at all that metadata. Something else we're doing to get people back engaged with the content is connecting to our collections through our main catalog. So we're not putting individual records in there, but we are using a new feature called featuring catalog with bibliocommons where you can tie a search into another resource. So if you look up the subject expo 86, which was a big fare that happened in Vancouver, we show up fourth in line. So this is brand new. I did this just before I left and nobody knows it yet. I'm dripping with power and hopefully that will bring some more eyes and again we can try to get more engagement user testing, put a survey up, who knows. And then we want to do a program called memory lane where we're taking some of those stories and we're taking them out with groups of seniors to use them as conversation generators and it becomes sneaky user testing as well as again getting that story city collection out there. So we think that would be a fun way to do that, been trying to get that one off the ground for a while. And then we all know my tours, yes. So we are clients of theirs. We have a couple of tours based on older projects that we did, but yeah we can relook at that story city stuff and put it in there. And I think I'm there. So yeah, so like I said we're nowhere near where we want to be but we're going to get there and just being here for me is going to help me come back to Vancouver with hopefully some ideas and some connections for people who I can pester and bother and etc etc. So, oh I had, I even tried, it says Kiora Rawa to you but I accidentally got rid of it but thank you.


Hello, you're watching the International Daily Roundup by People's Dispatch, where we bring you some of the top stories from around the world. Let's take a look at today's headlines. UN Climate Panel publishes major report on adaptation, volunteer teachers, health worker killed in the Philippines, UN Security Council expands arms embargo on Houthis, and Latin American scholars refuse ties with Israel. We begin with a report on climate change. The impact of climate change has been far greater, more frequent and disruptive than previously understood. Humans and natural systems are already being pushed beyond their limit to cope. The United Nations Intergovernmental Panel on Climate Change released the second volume of its landmark sixth assessment report on February 28th. Authored by 270 scientists, the study focuses on impact, risk, vulnerability and adaptation. It states that over 3.5 billion people or over 45% of the world's population are living in areas highly vulnerable to climate change. Between 2010 and 2020, 15 times more people died from floods, droughts and storms in South Asia, Africa and Central and South America. Not only is climate change causing ecological damage, it has led to displacement and threats to food systems and water supplies. If temperature rise crosses the 1.5 degree Celsius threshold, then many changes could become irreversible. 14% of land species will be at a very high risk of extinction, 8% of global farmland could become unusable, coral reefs could decline by 70 to 90% and there could be thawing of permafrost. By 2050, over a billion people in coastal areas will be at risk of climate hazards. The IPCC report points to large gaps in adaptation due to lack of funding, political commitment, information and a sense of urgency. It also notes loss and damages inflicted on nature and people due to climate change. Despite consistent appeals by poor and vulnerable countries, the Global North has refused to properly address climate finance and loss and damage. We now move on to the Philippines where two volunteer teachers, a community health worker and two indigenous people were killed by the armies last week. They were killed while returning from a community visit in New Bataan in the Davao de Oro province. The Philippines army later claimed that five people had been killed in an Amna counter with the band New People's Army, which is an armed wing of the Communist Party of the Philippines. However, rights group Karapatan stated on March 1 that the killings constituted a massacre. It stated that five people were civilians and not rebels or combatants. Karapatan has denounced the massacre as the latest in a long history of fascist attacks on Lumard schools, teachers and communities. They have been violently targeted and displaced under President Duterte's so-called anti-insurgency campaign against suspected communists. Estimates suggest that over 400 people have been killed in such operations. Lumard schools have been attacked and shut down on claims of alleged ties to the NPA. Among those killed in last week's attack was Chad Errol Buk. He was among seven teachers who were arrested during a raid on a Lumard-Bakwit school in Cebu, which is an indigenous school, last year. They were released three months later after the trumped up charges against them were dismissed for lack of evidence. Karapatan has said that Buk continued to be targeted and red-tagged by Duterte's counter-insurgency agency, the NTF LCAC. In our next story, the United Nations Security Council has imposed extended arms embargo on all members of Yemen's Houthi movement. The resolution was passed with eleven votes in favour and four abstentions on February 28. Monday's resolution was brought by the United Arab Emirates, which is part of the U.S.-Bagged Saudi-led military coalition that has invaded Yemen. Now in its seventh year, the war on Yemen has directly and indirectly killed around 377,000 people. An estimated 70% of those deaths were of children. There has been an escalation of fighting between the Houthis and the Saudi coalition in recent weeks. Houthi leader Mohammed Ali Al-Houthi condemned the United Nations resolution on Monday, saying that it had ignored the coalition's crimes. He added that any arms embargo which did not apply to the alliance had no value. Despite pledging to withdraw from the Yemen war, the United States has recently also deployed arms to the UAE. The UNSC resolution also describes the Houthis as a terrorist group. Norway abstained from the vote over concerns that using such terminology without a clear definition would have a negative impact on efforts for a political solution. It also said that it was worried about the unintended humanitarian consequences of the new language. Millions of people in Yemen are facing famine with conditions set to worsen as the world food program faces a funding shortfall. And finally, over 220 Latin American academics from 15 countries have pledged to reject ties with Israel. They have committed to refuse participation in academic exchanges and collaborations with the Israeli state and complicit institutions. The academics have also pledged to decline funding or sponsorship. They have released a joint statement to this effect based on the guidelines set by the Palestinian Committee for Academic and Cultural Boycott. The statement is in response to a call by Palestinian society including the Palestinian Federation of University Teachers and Employees Unions. Signatories have also called on their universities to suspend cooperation with their court Israeli accomplices. They have also urged their ministries of education to suspend cooperation with complicit universities and Israel. The Palestinian BDS movement has highlighted the key role played by such institutions in developing, maintaining, implementing and justifying Israeli apartheid. These institutions also hold a uniquely close relationship with the Israeli security military establishment and Israel's armed producer. Hundreds of academic departments, unions, centers worldwide have issued statements in solidarity with Palestinians. Many have advocated BDS and most have recognized Israel's settler, colonial and apartheid regime as being the cause of the violence. And that's all for today's episode.

One thing that makes it very interesting, and I think when I started my career, this was not the mindset at all, is that there are new forces that need to be taken into account when designing distribution networks. So there is a mindset shift of our decade that we all here in this room will have to face.


What's going on everyone Sam here with late and sports cards? We are doing 2022 Penini prism WNBA hobby six box break number three random team style Here's a look again at your random results as always you can find these on the website onto the results tab as well as the Lincoln Chat, let's get into it guys.

Hi, and welcome to the session. Let us discuss the following question. The question says, find the distance between parallel lines. First fact is, 15x plus 8y minus 34 is equal to 0. And 15x plus 8y plus 31 is equal to 0. Before solving this question, we should know the formula for finding the distance between two parallel lines. Parallel lines, whose equations are ax plus by plus c1 is equal to 0 and ax plus by plus c2 is equal to 0. Then the distance between these two parallel lines, that is d, is given by mod of c1 minus c2 upon square root of a square plus b square. With the help of this formula, we will solve this question. So always remember this formula. Let's now begin with the solution. First equation of line given to us is 15x plus 8y minus 34 is equal to 0. And second equation of line given to us is 15x plus 8y plus 31 is equal to 0. On comparing the first equation with ax plus by plus c1 is equal to 0, we find that a is equal to 50, b is equal to a, and c1 is equal to minus 34. On comparing the second equation with ax plus by plus c2 is equal to 0, we find that value of a and b is same, and value of c2 is 31. We know that distance between two parallel lines is given by mod of c1 minus c2 upon square root of a square plus b square. So we can now find the distance between these two parallel lines by substituting the value of c1, c2, a, and b in this formula. So distance between line one and line two, that is d is equal to mod of minus 34 minus 31 upon square root of 15 square plus 8 square. This is equal to 65 upon square root of 225 plus 64. And this is equal to 65 upon square root of 289. And this is equal to 65 upon 17. Hence the required distance between line one and line two is 65 by 17 units. This is our required answer. So this completes this session. Bye, and take care.


Okay, I'm Abel LaTrope. For those of you who don't know me, I'm a security consultant with ISAC Partners and you are here for exercise in messaging and presence ponage. I apologize for shutting off with a pun, but you do what you have to do. So I'm gonna go through a few different things here, starting off with just kind of the basics of XMPP if anyone's not familiar with it. Go over a tool that I developed for the kind of manual portions, just sussing things out. Anybody who's familiar with WebScarab or Burp will kind of know the drill. Then go over a few of the kind of more tempting extensions to mess with in XMPP and then a couple of the better ways to do that. So for anyone who is not familiar with it, it used to be the Jabber project which often times is what people remember it as still. It's mostly used for IM although they're trying to expand it out into a kind of ridiculously broad range of things.  So the main reason that I chose it, it's everywhere. Most people's work chats go over XMPP at this point. And as usual when you've got decision making via committee, it's an open standard. Things tend to go in somewhat conflicting directions and then you have all of the additional problems introduced by the choices people make in the way that they implement it later. So as you'll see once I get into more of the details, there are hypothetical solutions to a lot of these problems already being recommended but they're just not being implemented because some of them are too complicated and sometimes people just get a little lazy or want to do a very low overhead client and just don't put it in. So the basics of how it works, it's decentralized. You don't have one almighty server the way you would with AIM or something. The usual format username, that's server name. It's really, really widely used according to the source that may or may not have been Wikipedia 10 million people. I have no idea how I can get that is. The requests for comments are just huge. I mean, it's incredibly large. You've got maybe several hundred at this point and some of them run into like small books. So anyway, it runs with TLS for encryption and SASL for authentication. Yeah, sorry, I just skipped down for the next one of my notes. So I'm gonna back up. We'll just do that over. The less diligent server certification is you're only as safe as that is completely lost my place now. So go with the third bullet. HTTP binding and this one's kind of fun because all of the kind of web inline clients that use Jabber use this. So you'll have kind of an HTTP wrapper with an GUI XMPP center and I'll kind of have more fun with that later. And then the most common thing you see is an XML stream where it's initiating a connection and then you just have kind of this ongoing document that's getting added to you as you go along. So there are a few different types of stanzas but all of them have these attributes in common. Obviously the two in from are pretty self-explanatory. JID stands for Jabber ID. You get a lot of legacies in the name since the switchover is pretty recent. There's an ID which is optional depending on stanza type, some things require it. And scope of uniqueness is flexible on that. Sometimes it's only unique to a server. Sometimes you want it to be a little more global than that. The type is just for specifying the purpose of the stanza. So you end up with get set, all the usual stuff. XML language is basically a relevant for security standpoint. It only affects the way it displays. So the first type which I won't deal with too much is just the info query. You see a lot of these in the beginning when you're setting up the connection and then tends to be kind of keep alive sort of stuff but there's not a ton that was super interesting here. Presence is one that ends up being fun because this is just a huge volume of the messages that you see in the traffic. Many receiving updates from one.  So you see just a ton of this when you're looking at the dumps. Message is exactly what you think it is.  You're saying hi to your buddy and it's going out this way. So on to the proxy that I put together for kind of looking at these things. If any of you are a blackhead and some of my coworker Rachel Engels talk it basically extends the product that she had put together which is just kind of a really lightweight version of a web scare burp type of thing, you know, just it was designed for kind of speed, very low feature set, not a lot to mess up basically. So I kept the HTTP functionality for that and just kind of tacked on, you know, the ability to do very similar things but with XNPP data instead. So I also added the ability to do, you know, multiple concurrent listeners. You're not just tied to, you know, local host 8080 and you aren't stuck with the same thing over the course of the session. It's got the basic, you're just a transparent proxy watching what's going by and also the kind of intercept, twiddle forward thing. So yeah, all around it should be very familiar for anyone who's used general attack proxies before just Brex MPV. So this is kind of a look at the listeners tab. You have the option of creating whatever you want. Couple of improvements that I want to make because currently you have to kind of reset all of those fields and then hit start top twice and this kind of offends me on a minimalism level. The pass through mode, you've just got blob the text scrolling by. I realized that I probably want to add timestamps at like 10 a.m. this morning. So clearly didn't have time to do that but we'll be doing that before I toss it up on our servers. Intercept mode, again, you know, just very simple, very clean. The thing you see in the upper left hand corner, I haven't actually implemented for XNPP yet. We've got kind of this interesting thing that you may have heard if you went to our talk where you can send the commands to external shells and you know, manipulate them further if you want kind of a good tie in for making this the basis for a fuzzer. And basically, you know, just modify it however you want. Hit the send button. It passes it on to either the client or the server depending which you're currently trying to manually fuzz. So I mentioned a couple of things that I kind of wanted to change before this goes up. Also want to add replay functionalities so that you can just, you know, send the same command. Also wanted to be able to have, you know, because we got the concurrent listeners going, it seemed like an obvious thing to be able to take a packet that was destined for one of those listeners and instead send it to the other so that you can kind of, you know, get some more fun in that way. I also want to have a more legible detail view because as anyone who's tried to read XML just, you know, without any of the invitation would know.  And then obviously the wrapped XMTP handling that I was talking about earlier currently, you know, it's HTTP or XMTP view so you will see it in the HTTP tab but it's not as, you know, elegant as it could be in terms of actually being able to get in there and manipulate it a little more easily so. So as I accidentally mentioned earlier when I got a little ahead of myself, the protocol extensions are specified kind of by community. You know, anyone can submit it. It does the usual, you know, IATF style thing where it goes through draft and experimental and whatever and, you know, gradually just gets kind of hazed by virtue of people implanting it. There's a core set of protocols but it's really grown like crazy from there. I feel like I barely scratched the surface in going through these. I just picked some of the more obvious ones because it's just huge. I mean, it's an enormous volume of information. So I kind of picked out a few select highlights, things that, you know, left out at me as being honestly really to the easy to cause trouble with in addition to being, you know, fun. So the interesting thing too is that you'll find kind of a random assortment of things implemented. Like a lot of the ones marked experimental, you'll still find fairly popular products.  So, the first one that I wanted to take a look at was PubSub, obviously, given that I had my eye on DOS. This was kind of the obvious first choice. They just, yeah, this is another one where it's kind of run away. You have to focus on the main obvious use and just chat because they want to use it for everything. Basic idea, you know, it's kind of an observer slash push system. You've got one publisher pushing to many observers. It's broadcast to users. So this gets used for things like, you know, my friend updated their blog entry so I'm being notified in my feed. So the leaf nodes it's mentioning here on the bottom line, those are basically nodes that only contain published items. So you've got the parent, which is the publisher, and then the leaf, which is the publisher. So the fun thing about the publishers in this situation is that they have more or less complete control over the nodes. So pushing to subscribers really doesn't require that much of their participation. The interesting thing here is that, you know, again, they have a specification that would give users the ability to block PubSub nodes, but no one uses it. That would be, you know, XEP 16, if anyone's following along at home.  I think the problem is just that it's really, it's way over complicated. You know, it's this big privacy lists thing where you have to go in and maintain who is on it. And, you know, you can block by JID but also subscribe state and you can block specific types of stanzas. And it would all around just be really intimidating for a non-technical user. So what you see people do much more often is 191, which is great if you want to block a specific user but doesn't help you out when it's PubSub nodes that are the problem. So this is what most of the web applications that do kind of a little inline chat applet use. Some kind of take additional precautions but basically the only security mechanism that's mandated is this little request ID. And, you know, as usual, it's supposed to be non-sequential but it's generated by the client. And, you know, again, anyone who's met developers, if you have a random ID, half of them won't know that it's supposed to be used for a security purpose and so it will end up being implemented in a sequential fashion. The other interesting thing, which I kind of noticed the last minute, was that they recommend you not to use the regular authentication. They recommend you use HTTP off. So then you kind of get into exposure to all the usual web app phones. And then multi-user chat was another obviously fun one. It basically wants to be IRC. So, you know, you've got the usual kick-ban mods admins. And then here again, you've got kind of, I wouldn't say godlike powers assigned to the parent nodes but they can mess with you more or less, it will. So, anyone here, raise your hand if you've done a Google Vanity search? Anyone? Okay, I think most of you are lying. And the upshot is I had done one to see what people were saying about the talk and had happened to come across this, which entertained me, so there you go. So, the DOS protections that they recommend are really, I wouldn't say insufficient but they're kind of low tech. It's more relying on human intervention on the part of the admins than actually in having it be resilient in the first place. So, here's where the presence traffic really becomes fun because there's just so much of it. I mean, you're picking at a fairly high rate and so if you have a reasonable number of people involved in a multi-user chat or something, it's just, it's a ridiculous volume of traffic. And there are just kind of scalability issues, partly pertaining to that in general. Some of the ways that they recommend that you, actually most of the ways they recommend that you mitigate it are not implemented widely. Limit connect attempts by IP or JID. I was just sitting there, connect, connect, connect and you can do it for an hour and they won't even notice on a number of different clients for most of them. So, kind of ditto with unauthenticated connections being denied for whatever reason, a lot of, like even Google Talk will let you log in over HTTP if you're really so inclined. So, the only real defense you have against spam instant message spam is to restrict access to the pub sub and multi-user chat functionality which kind of defeats the point of using XMPP in the first place. I mean, you wanna be able to do those group chats, you know, particularly in an office situation where you've got a lot of people trying to collaborate. If you can't have access to that, you're not really getting the full use out of your internal chat. The other things they recommend are, you know, stand to size limitations and things like that and, you know, again just don't really see it implemented in the wild very often. And then another problem there is just parser errors are indistinguishable from Pigeon just having a bad day frequently. I noticed maybe half the time I'd actually see a little XML error that mostly it would just, you know, spit back out the connection. And half the time, you know, I have these problems when I'm not fuzzing with Pigeon. So, it's really, there's not that same level of user interface acknowledgement that you would get in web browsers yet. They just haven't really caught up to doing, and, you know, obviously not getting the whole controversy on whether that little secure thing in the header actually helps or not. But you really just don't have equivalence for chat clients yet. So, if you have a parser error, then it's just gonna choke and it may tell you that you had an XML error or it may just mysteriously refuse to connect. So, the aforementioned problems tend to make amplification attacks pretty likely. Obvious targets being multi-user chat and PubSub. Again, you know, they just skip straight to admins can block specific JIDs only if you have any kind of coordination. Blocking specific JIDs is not going to be a fast solution. It's not gonna be an effective solution.  So, in the XML parsing, they've done a good job on some of the more common types of attacks like entity expansion. I was trying to find a way to do that and didn't go up with one. But in terms of some of the stanza-specific requirements, you can make it choke in entertaining ways a lot of the time. One of the issues that I encountered early on kind of by chance, actually, as I was kicking this off, a coworker had dumped, I think it was spew from a malfunctioning ethernet adapter into our common chat room, which turns out kicked everyone who had a live purple-based chat client off. Unfortunately for me, that was a known issue, but still unfixed. So a lot of these DOS issues kind of blend into the XML parsing issues. Just if you have any kind of malformed XML, the solution is usually disconnect. So, here again, the chat logs kind of from the horse's mouth. I feel like, as I was mentioning, depending on I barely scratched the surface on this, there's so much more to go into in the XCPs just, and constantly adding new material. So, these are the resources that I kind of found most useful in putting it together, and hopefully I will be able to get the proxy up on our website relatively soon. You can either look for it there or contact me at my personally mail address up there if for some reason it doesn't end up making it up soon. So, questions? All right, thank you.


In this video, we'll look at naming esters. Esters are somewhat similar to carboxylic acids and amides. They have a carboxyl group, the C-double bondo, plus the extra oxygen. But where in carboxylic acids that extra oxygen is bonded to a hydrogen, here for esters, the oxygen is bonded to a hydrocarbon group. Esters are synthesized, or made, by joining a carboxylic acid molecule with an alcohol molecule. And we'll look at this reaction in a later video. So, just to reiterate that point, to make esters, you react a carboxylic acid with an alcohol. So here's how this first ester would be made. You would react hexanoic acid with propan-1-ol, and they would join together, and you would get this molecule. The part on the left, the part that's directly attached to the carbonyl group, came from the carboxylic acid, and the other part used to be the alcohol. So, to name this, we call the part that used to be the carboxylic acid the main chain, and it takes the suffix 08. So, this part of the molecule is called hexanoate. And the other part, which used to be the alcohol, is named in the same way as an ordinary alcohol substituent. So with three carbons, it would be called propyl. And then you put these two parts together, and the full name is propylhexanoate. Now, note that there is a space between the two words. This is the only time with esters that you'll leave a space between the two parts of a name. No hyphen, no comma, just a space. Okay, how about this second one? First, identify the main chain. That's the bit on the carbonyl side here. And it has two carbons. Don't forget the carbon that's part of the carbonyl. So we'll call that part ethanoate. Then the substituent part has four carbons, so it's butyl. And together, that makes butylethanoate. Lastly, this one. Again, identify the main chain. It's here, but it has a branch on it. Well, no matter, we deal with it like any other molecule. The main chain is five carbons long, so pentanoate. And on carbon number three, there's a methyl group, so it becomes three methyl pentanoate. But then we need to indicate the esters substituent here. That has only one carbon, so it's going to be called a methyl as well. Because it's the special esters substituent and not stuck to the main chain, it gets put out the front of the name as a separate word. So that gives us methyl three methyl pentanoate.


What's going on already? Chris from jassescasebrakes.com doing R&B number one for one spot in our Jastv's 190 box hit parade wax already baseball mixer right here We have three spots left straight up But we're going to do a R&B for one team what it's going to work get the team and the hit parade mixer Whatever hits these R&B number one spot ends up with what is hit in that random number block And it works just like our usual R&B breaks everyone will get one number through zero from zero to nine With each spot they buy of R&B number one gets a mic trap three out of ten They have number three in the R&B will get the trap, but it's going to make it really easy because Carl gets a whole ten spots in this R&B. So this is really just kind of for semantics I'll roll a dice in randomized for our R&B spots for Carl six and four ten times total. So one two three four five six seven eight nine and ten tenth and final time just for posterity six We carl down to Carl and ten times here one two three four five six seven eight nine and ten So one down to six The way it goes I'll grab a blank sheet real quick kind of match it up like that But as we know Since Carl grabbed all the spots for one team So Carl with spot zero all the way down in spot nine a little grand opening grand closing That's how the way it's gonna go for R&B number one for one spot in jasmine's 190 box hit parade wax party mixer Thanks again folks jasmine's cakes breaks calm We got three more spots showed up. We'll do a few more of these R&B's for teams. Thanks again. Have a good one Bye


well good morning my friends and welcome to day two of my travel vlogs for go wild i just woke up oh my sound machine's still on i can probably turn that off oh anyway um so i just rolled out a bed i tried to upload my go wild vlog last night well because the internet's kind of shoddy here when my computer goes to sleep and the you know screen stops uh it doesn't just keep going like that's what it does at my house where it just like keeps going in the background doesn't do it here unfortunately so i'd only gotten like about 20 percent uploaded last night so i quit the upload and i re-uploaded it so now i'm at 39% so i think this is actually going to be up before i leave for um the May Designs brunch but because it says it's um one hour and 20 minutes remaining so i mean that can always fluctuate a little bit so i'm working on it guys i'm working on it but now i know so i might uh change my settings in my computer um if i'm able to edit tonight so it doesn't you know like so my screen doesn't sleep so then it will just keep going i don't know i'll i'll mess a little bit more so anyway um the reason i wanted to talk to you guys this early in the morning is because there's a cureg here i've never used a cureg it's like a freaking space machine like i don't i don't know how to use it so um let's try to use it together mm-hmm why don't me so i'm gonna decide to go with this big aloe tea it's the only one they have but i like an english breakfast tea my faves okay it looks like you just fill it up with water and then you dump it in i've got hit the button you guys i think i i think i did it so that's heating is it just heating the water oh sweet okay i did not see this it says three minutes until fresh bird coffee but i don't want coffee i want tea but that's the little like pack i put in look it's doing it oh i'm so excited i got the cureg spaceship to work yay oh my gosh the freaking nuts yeah so that's what's going on here this morning i'm just gonna have a that's really loud um i'm just gonna have my cup of tea take a shower get ready um but i don't have to be over to i think it's called the refinery i don't have to be there until 11 30 i want to say i think it's 11 30 let me just double check yep it's 11 30 to 1 so um that's the plan for that and then registration opens at two and it's from two to eight so it's like a long thing so i think what i'm gonna do is because i'm gonna eat at this thing so i'll have we're gonna have brunch so it sounds like there's gonna be um some food served which is gonna be awesome like something else i don't have to pay for plus i don't really like know where to go like that's a challenge here i'm like i don't know and i don't want to like just eat you know broom service and then after the brunch i'm gonna run back to the hotel here and then i'm gonna grab um this stuff so i have my like you had to print out your ticket um i guess it makes registration like go really fast you can just like hand it to them so i have to like look up everything and then i'm also going to grab this it's my bag of swag that you can't really see very well but it has um stuff about my info like information about my washi shop um and then i have like business cards and samples uh two samples to give to everybody that i give a card to so yeah i think i made three almost 400 of those so yeah that was uh that was a lot but it was good it was good but i'd love to get those handed out today if possible but there's gonna be like a big line over by registration so i figured i would just kind of start at the beginning and then like hand out stuff and then just get in line myself when i'm done so um because there's like 1200 attendees you know we got like 300 or 400 so i could hopefully give them all away and if i don't give them all away today i will bring it um tomorrow because tomorrow uh is friday and that's the first official day of the conference so anyway i'm gonna enjoy my tea and i will check in when um things get more interesting we're at the may design front what's going on a bunch of people at dinner and i don't want to show people's faces on the internet that would like knock my hotel room oh my gosh you guys i am like still geeking out that erin kondren said hello to my vlog to my vlog that's so i got her to sign my cover right there this is emily stay wild love erin yay oh
