In connections, we think about the teaching and learning dynamic differently. Rather than a linear process from teacher to student, we see a spiraling dynamic process of learning, re-learning, unlearning, and new learning. This new way of thinking about teaching has roots in mind, brain, and education science, and neuroconstructivism. Our classes are centered on the belief that knowing how a person's nature, genes, and nurture, upbringing, and environment, combined with his or her own free will, your choices or decisions in life, determine learning outcomes. This philosophy of learning is compatible with most major educational best practices and mainly differs in how we interact with students and how we leverage technology. 1 plus 1 equals 3. We believe that learning is a social construct. You have a good idea and I have a good idea. But when they are exchanged, we both learn more and the result is something better than we could ever hope for on our own. Visible thinking. We believe that the person who does the work is the person who does the learning. So our courses create lots of space for reflection and interaction to make thinking visible. As authors, Rich Hart, Church, and Morrison promote, differentiation, giving every person what they need, does not mean treating them equally. We understand that brains are unique, therefore different people have different potentials in different subjects. For this reason, we use different resources and interventions at different times in order to maximize your potential in a subject area. Begin with the end in mind. Backward design. All educational planning from the most macro level of national systems planning down to the specific teaching intervention you'll be using with Johnny to help him learn to decode the phoneme B. Should use backward design. In fact, as teachers or administrators, we must decide what the objective is. Then we must choose what we want to use as success criteria and indicators that we are reaching our objective. Evaluation. Finally, we can then select the best teaching methodology, strategy, activity, and resources to meet our objective. To explain this further, let's take a tour of our classroom. Flipping. Using backward design logic, the courses in Connections are planned to maximize the best use of our face-to-face or synchronous time by flipping. This means you watch a video summarizing core theories, concepts, and ideas before coming to class, so that when we are together, we can pull those ideas apart and go deeper to explore the concepts in your own personal context. Since rote memorization knowledge, dates, facts, formulas, names, places, theories, Google-able knowledge can be learned and reinforced by frequent quizzing. We also encourage you to take a quiz in every unit as many times as necessary to learn all the basic unit concepts and to get 100% on every test. This permits us to share a basic level of vocabulary and conceptual knowledge when discussing the topic. Critical thinking through our discussion boards and class exchanges. It's for this reason that each course unit has one or more discussion board prompts. These prompts are not only meant to get you to reflect, but also to listen and exchange ideas with others. Challenge prior beliefs you might have had, and open your mind to different ways of thinking. Many libraries. In Connections, we understand that people will take our courses from different starting points of knowledge about the topic at hand. This is why we have created many libraries or bundles with a variety of resources for each topic. The libraries have beginner, intermediate and advanced level resources in video, peer-reviewed articles, books and university papers, which permit entry points to knowledge at different starting points. We encourage you to explore the material and find your own sweet spot entry point so you can build off your own existing knowledge base and grow towards more sophisticated understanding. 3-2-1 Reflection To think clearly about complex ideas, we also need reflective time, not just instruction time. In traditional learning environments, we often share lots of new information, so much so that the experience can feel overwhelming. Incorporating reflection time is a part of every best practice teaching encounter. In our courses, we often ask you to question your own belief systems. We will ask you why you do things that might have become habituated over time and to justify your actions. To reflect as well as document our growth with topics, after each encounter, we ask you to write a 3-2-1 reflection. 3 things you didn't know before. 2 things you will continue to research. 1 thing you will change about your personal or professional life. Writing is a form of thinking. Finally, we know that to write well, one has to read well. To read well, one has to read a lot. In the courses, we want to give you the opportunity to learn to both read and write better. The courses are purposefully writing intensive because it is a vital dimension of thinking. We realize some students will enter our course writing well in colloquial form, texting, but with difficulty writing academically. Thus, if you are open to the feedback, you will become a better writer through this course. To guide you, we have developed a series of videos to explain APA, American Psychological Association format, which you are encouraged to explore immediately. You should also take the APA quiz until you get 100%. Course outline, recommended process. We recommend this process so you can take advantage of the courses to the maximum before the live class. 1. Watch the video. 2. Post on the discussion board. 3. Dig into the bundles. 4. Come prepared to talk. During the live class. Participate in the discussions, talk and share ideas and or post on the chat. After the live class. 1. Complete the 3-to-1 reflection. 2. Respond to your fellow learners on the chat. 3. Retake the quiz if desired. Attitudes. We know this is a very different course format than you have likely used in the past. We also know it works. After documenting three years of this particular instructional design at the Harvard University Extension School in the Neuroscience of Learning course, we can demonstrate that this format enhances and increases student learning outcomes as reported by the students themselves. We know. If you are open to feedback, you will learn faster. If you listen and learn from your peers, you will learn broader perspectives on the topics. If you dig into the many libraries, you will learn deeper. If you participate, you are not only being generous intellectually, but you are opening yourself and your ideas to critique, and therefore you will learn more about yourself. If you reflect, you will know what you know and what you don't know, which will permit better learning the next time. Welcome to Connections.


Let's all create all different mosques and all different spaces because we all speak different languages and we're all going to argue when it comes to the time of Niyaz. This food is too dry, this food is too bland, this food is too spicy, this sweet is too sweet, this sweet is not sweet enough. If we begin to segment into all of these sorts of populations, then in reality, what can we achieve in terms of making differences? It's about taking those theories being presented by the Ahlul Bayt, A.S. And at the end of the day, being ready to practice them. Today, for instance, we live in the United States of America. The followers of Ahlul Bayt, A.S., are a number that is so minute, we in reality probably can't even state for sure how many a number that we are. We talk, for instance, that the population of Muslims within this country is about 3 million Muslims in the United States, meaning 1% of the population. Followers of Ahlul Bayt, if we were to take, for instance, 10% of that 3 million, 300,000, right? Not that much, right? So we come forth and we see that one step that we need to make as followers of Ahlul Bayt, A.S., is being able to engage our numbers, the numbers that we are in such a minority and being able to work with other institutions so that we're able to make real differences. Number one, for instance, if we go ahead and take this one 10% of 3 million, 300,000, right? Or 30,000, 300,000 people, right? All across this country, and then we begin to segment them. This is the Pakistani community. This is Khosha community. This Iraqi community. This is the Iranian community. This is the Afghani community. And let's all create all different mosques and all different spaces because we all speak different languages and we're all gonna argue when it comes to the time of Niaz, this food is too dry, this food is too bland, this food is too spicy, this sweet is too sweet, this sweet is not sweet enough. If we begin to segment into all of these sorts of populations, then in reality, what can we achieve in terms of making differences? At the end of the day, if the goal is Quran and Ahlul Bayt, A.S., then we need to start breaking down barriers for real. And believe me, I get it. I'm Khosha, right? I get it. I get the importance of culture. I'm gonna get in so much trouble. I get the importance of culture. I get the importance of language. I get the importance of a specific restriction when it comes to food or in other terms of events and so on and so forth. But at the end of the day, the community is moving at a pace that's far faster than our cultural backgrounds. So in 10 years, what's gonna happen? And then in 20 years, what's gonna happen? And then in 30 years, what's gonna happen? If every single day we continue to focus on this initiative of building communities that speak these languages or soul the ethnocentric, what's gonna happen in 30 years?  Because the language has been so stressed that people are gonna go find other places where they can vent, where they can have other avenues, or they're gonna be sitting on YouTube and watching the Majanists at home every single day instead of coming to the gatherings. Now I know we have Medjus here in English at MFI throughout the entire, I'm talking about this community, I'm talking about larger, right? The poetry needs to be in English. The matam needs to be in English, right? The food needs to be like cheeseburgers and pizza, right? Because it's too spicy for some people. Not right now, but in 10 years, in 20 years, in 30 years, because again, that's the reality of where we're heading to, right? So we need to start thinking in this regard. Furthermore, we need to come forth and we begin to need to break those barriers between cultures, not only in regards toward spaces, but in regards toward marriages, for instance. Ahl al-Bayt, alayhimu s-salatu wa s-salam, the Seventh Imam al-Qadim, Imam al-Aribna al-Mussaradah, Imam al-Jawad, Imam al-Hadi, Imam al-Askeri, and Imam Sahab al-Zaman. Adjara Allahu ta'ala, Tharajah, alayhimu s-salatu wa s-salam, Allahumma s-salatu wa s-salam.  Imam Sahab al-Zaman is another narration that she comes from a Roman princess. The stronger narration, according to Alama, is that her mother also comes from sub-Saharan Africa. The Imams of Ahl al-Bayt, they didn't segregate, they didn't discriminate against who they were going to marry, for instance. It means there has to be an institution that's founded, again, within this framework of Quran and Ahl al-Bayt, alayhimu s-salatu wa s-salam, we need to push that sort of ideology forward. Furthermore, we come and we see, for instance, that this notion again, in terms of inclusivity, of being receptive toward people who were not Muslims before, reverts and converts, and not only telling them, look, this is a space for you and you know, we'll give you books and you can come and pray here, but we need to think deep down. I don't have the answer, we need to think deep down in terms of what mechanism is that we need to put into place in order to be at their support. Because they're certainly there during the time of Ahl al-Bayt, alayhimu s-salatu wa s-salam. And again, the reflux of Ahl al-Bayt is one, the second thing is practicing what Ahl al-Bayt practiced. And that brings me to the next stage, Ahl al-Bayt alayhimu s-salatu wa s-salam, as we know, the holy prophet, sallallahu alayhimu alayhimu alayhimu alayhimu alayhimu alayhimu. Hassan al-Mujtaba alayhimu s-salatu wa s-salam, al-Baqara al-Sadaq, when they saw the difficulties and the obstacles and the trials and tribulations of certain minority groups within their communities, they would go out of their own cells toward coming to their support. Specifically, women who were divorced or widowed and orphans within the communities. What are we doing in terms of building out institutions for those sorts of individuals within our communities? Again, these are things that we need to think about because that's what it means to put into practice what Ahl al-Bayt have practiced during their days. It's not only about building mosques, having majadas, and distributing nias. It's about doing things that are bigger because we need to understand the fact that a lot of people are doing it in the names of a lot of different people. Why is there no, for instance, domestic violence shelter in the name of Ali ibn al-Bathar al-Arayim s-salam? Why, for instance, do we not create a mechanism? Do we not create, for instance, an institution that combats sexual harassment and sexual violence in the name of Sayyid al-Shahadah al-Hussain al-Arayim s-salatu wa s-salam? Why are we not moving beyond the bubble that we're living in? Not you, but in general, in terms of actually carrying out that which Ahl al-Bayt al-Arayim s-salatu wa s-salam worked so hard toward carrying it out within their capacities. What are we doing? Where's our vision? Just an opportunity to sit back and contemplate during these days. They said, because they have to be a means to motivate us and to empower us so that we're going out and making that difference. Again, Allah subhanahu wa ta'ala states, you are the best of people, you are the best of Ummah, why? He gave you the Prophet sallallahu alayhi wa sallam. Alhamdulillah. Alhamdulillah, al-Labi ja'ala na min Ummati Muhammad. What an amazing blessing that we have a role model like Rasulullah Muhammad sallallahu alayhi wa sallam. What an amazing blessing that we have a role model like Ali ibn Abul Tadeb whose title that we cry over is Abul Atam. The father of the orphan, this is an amazing role model that we have in saying that others take inspiration in terms of his stand for justice. Yet we commit acts of injustice toward our spouses and toward our children in day-to-day basis.  We need to be in a state of reflection, contemplation during these days again so that we're able to utilize the light that we have been recipients of during these days of majadis and begin to reflect about how we can make differences.


So I'm Neel Sofel, a recipe engineer working on Ovid storage. Hi, I'm Vojta and I'm a developer also in Red Hat also working on Ovid storage. So today we'll talk about supporting 4K drive in Ovid. First we'll understand why we need to support this and then we'll dive into the challenges of trying to support 4K in legacy project that was started more than 10 years ago. And we'll focus on the interesting point of detecting block size of the storage and how VDSM is using it to create sodomain and how engine is using what VDSM reports to manage host that have different capabilities. And finally we'll look at some double shooting tips and we'll see hopefully we can see a live demo getting 4K storage. So first what do I mean by 4K storage? Drive has a minimal block size that you can write to them. You cannot write 3 bytes of drive. You can write only one block. And this used to be 512 bytes and in modern drives it can be 4K or you can have software to find storage that wants to use 4K. So the main reason we need 4K is 4I which is rather hyperconverged infrastructure which is hyperconverged solution with OSTED engine with Glaster and with VDO which is kind of complex but to create simple solution you need complex software behind it. So why do we need this? It means that you can take few cheap servers with some cheap disks and create together data center using the servers both as compute nodes and as storage. And you don't need to pay a lot of money to storage vendor for storage. Everything is built in and people really like this idea. Now what is VDO and why, how is it related to 4K? VDO is a new data application and compression solution for Linux. It can give you 10 times the storage space with the same hardware. So it's really nice that we can use this and Glaster solution wants to use VDO. Now VDO is designed to use 4K blocks. Everything is designed for 4K. It can work with, it can emulate storage with 512 bytes synthesized but it makes it slower. So Glaster guys want to use VDO in the way that it was designed to use. And of course some users bought newer drives. New drives can be cheaper and faster if they are 4K drives. And we want to support these users. So if you have 4K drives currently with file storage, you can use these drives. And we don't use all type of, we don't support all type of storage for 4K. For example in block storage, we don't support it yet. But we made all the infrastructure work so we can support it soon. So what are the challenges? Yes? Yes. Yes, yes. So what are the challenges of adding 4K support in the system? When it was created like more than 30 years ago, nobody thought that it's important detail. So one small issue, storage format assumes that the block size is 512. So actually we assume that we can write 512 bytes to a certain location on storage from different host in the same time. And this can really does not, cannot work with 4K storage because the minimal block size is 4K. So to mitigate this, we introduced a new storage format, V5. And the main advantage of this format or actually the main reason it exists is supporting 4K. And the different is that we change the storage layout so it can work with any kind of drives and use the same layout for 4K and 512. So supporting it should be much easier. You don't care about the type of storage, the layout is always the same. So the next issue, we have storage format supporting 4K, which was, by the way, available in 4.3. So everyone running 4.3 is using V5. But Sanok cannot detect the block size of file storage. So Sanok can detect the block size with block storage, of course, it's very easy. But for file storage, there's no PI to detect the block size. So Sanok cannot detect it and it was falling back to the old block size, which cannot work with 4K. And even if Sanok could detect the block size, it's not enough because VDSM and Sanok must be synchronized. When you create a storage domain, VDSM creates a storage domain before Sanok is used. So really, VDSM should detect the block size and tell Sanok which block size to use. So the solution was to add 4K API to Sanok. Sanok can be instructed now to use certain block size or certain alignment, which is also related to the block size. So for example, when we initialize a lock space, we can tell Sanok that we want to use one megabyte alignment and 4K sectors. So now we can support any combinations and VDSM and Sanok are synchronized. And this was also available in 4.3. So anyone running 4.3 has new Sanok with these capabilities. So the next issue, we have Sanok is ready, storage format is ready, but we have tons of code without coded block size. Here block size was outcoded to 512. And there are two issues here. The first issue, VDSM should not care about block size most of the time. Most of the code does not care about it. It cares only about size of volume, size of metadata files. The only place that should care about block size is the code writing to storage, waiting for storage. And this code should use the real block size and cannot use outcoded value. So the solution was very simple, moving to bytes or in more details changing or sending hundreds of patches, changing all the APIs in VDSM to use bytes, all the internal APIs. And now VDSM is sector-free. There is no code using the sector size, only the code writing or reading for storage, which is only a few places. And we can see an example of internal VDSM API. This was called set size in the past. I need the both size in sectors, outcoded to 512 and wrote this to the storage metadata. And now it calls set capacity, accept capacity in bytes, and writing new key to the metadata. So now everywhere in VDSM, you will not find size, you will find capacity, which matches other places in the VDSM that use this value. This name is also used by Leavield. So now the system is more coherent. So the next issue, how do you detect block size when there is no API? Well, we find that we can do this. We read QM a code, and in QM we found that QM knows how to detect block size by accessing the storage. Now, we will talk more about this later. It's a bit complicated, but we solved this issue. We can detect the block size. But of course, we don't have good tests in VDSM because testing was not popular and they started this project. And a big project like Python with poor tests is not something that you want to change because when you change something here, something there breaks. This is life. So we improved this coverage. Currently, storage code is the best coverage in VDSM. It used to be almost zero, and now it's the most tested part of VDSM. And we also are testing real storage domain and real volumes in VDSM. So we don't use fakes and mocks. We create real storage domain in local FS and in block storage. Like we have infrastructure like this TMP repo, which is test infrastructure that you can easily use in the test to create a local FS domain. We have similar infrastructure to create a block domain using real LVs on loop devices. So you don't need server. And in a few seconds, you can run many tests using real domain, getting volumes, getting domain, making changes, and make sure that everything works. And this is another infrastructure. We have a user domain feature that creates for you everything. You just use this object. It will create a storage domain for you. And then you can start getting volumes and making changes to these volumes. Before we made these changes, we took a picture of VDSM. So this is VDSM before. And this is VDSM now, much better. So VDSM was ready. Are we done? No, because it turns out that QM is not really ready for 4K. Like it works for most cases, but not for the case we care about, like Glaster with XFS. So the solution was to fix it. We went to QM source, find the issue, send some patches. And now QM can detect block size in a better way. And in the case it cannot detect block size, it fall back to a safe value, which works. And the last issue, after everything was ready, we found that we cannot boot a VM with 4K block size. So first, we found that if you boot a VM on a 4K domain, the VM thinks that this is a regular storage, which is found out at 12 bytes sector size. And we learned that we can configure a leverage to use the correct block size. And then we found that the VM will not boot. Well, it turns out that BIOS does not support booting for 4K. So the solution was not to use it. So what we have now is a 4K storage. QM knows about the correct size. But the VM thinks that this is old drive with 512 bytes. So this is basically what the solution that we can provide now. The guests think that this is 512 logic block size. QM knows the real size. QM can do efficient IO to the storage. And if the guest is trying to write something less than a complete block, QM will do emulation, which is not very fast. But actually, we don't have any data yet on if it's better than what we had before or not. But this is what we can do now. So how do we detect the block size, which is the interesting part? First, let's see how QM does it after we fix it. So this was actually the fix. We start with reading one byte with direct IO. This will obviously fail because direct IO cannot read one byte. Now, if it does not fail, it means that we cannot detect the block size, which is the case with, for example, empty file on XFS. Because XFS is probably doing some tricks to avoid IO if we try to read, if the file is empty, right? Why go to storage? So in this case, QM will fall back to 4k, which is safe. And if it failed, we know that we can try the next value. The next value is 512. And if it succeeded, we know the correct block size. And if not, we try the next value. And either we found the value or we failed. And in this case, QM will fail the operation because you cannot use direct IO as this slide. So the issue with this is that QM cannot detect block size on an empty image. So QM image create was changed to always look at the first sector. So this issue should be solved. And this also available in 4k in the version that we require. And the next issue is, of course, NFS. We cannot detect the block size on NFS. In this case, QM will fall back to 4k, which works. And even seem to work faster, although it can cause some unwanted alignment changes. But it seems to work better. So how do we do it in VDSM? We do it in a similar way, but a better way that QM cannot use because QM is checking the image file. In VDSM, we create a temporary file. And now we can use a better way within write instead of read. And we use the same logic. We try to add one byte and then 512 and then 4k. But in this case, we always detect the block size. So there was no issue with the cluster or XFS. And of course, with NFS, we cannot detect because NFS does not have any requirements. NFS does not really do direct tile when you have file open for direct tile. There were some issues with the cluster. I did not add them to the presentation, but we had a lot of issues with the cluster. Gluster is very creative storage. You have to ask for direct tile. And then you have to, there's another settings. I really want direct tile. And if you use both, you will get direct tile and everything works. And if not, Gluster can avoid doing direct tile in some cases and detection may fail. And some operation may fail later. But if Gluster is configured correctly, and this is the default configuration that you should get with Ovid, then everything should work. So Vojta will continue to explain how to use all this information. OK, thanks, Nir. I would like to show you how we use all this stuff in VDSM. So before trying to use even for case storage in VDSM, you first have to enable it. Luckily, in recent versions, this is enabled by default. But for any reason, around older versions, you have to enable it manually in the VDSM.conv.de slash Gluster.conf. And you have to set enable 4K storage to true. As I said, in recent versions, it's enabled by default. But it's useful to know this option if you have any issues or for any reason don't want 4K support. You can easily disable it by turning this option off. First basic functionality which VDSM provides is host capabilities. It reports the capabilities of each storage domain time for a given host, what is able to support. And as I will show, it will be later on used by Engine, this information. If you check the logs, you can see the values. But also in terms of code, which is more readable, I show it here. Of course, we support 512 4K. But there is also block size auto. In logs, you will see it as block size equal to 0. And it means what name suggests that if you request block size equal 0, you are requesting VDSM to detect the block size automatically. And while we do need it, I will also show it later. But for now, I just mentioned that we do the block size detection in any way because we are good guys and we expose the block size in our API so we validate the user input. So if you request any block size, VDSM will do the detection of the block size and will validate if the requested block size is valid. And if not, it will throw this exception. I will return back to this exception later on because it can sometimes in some setups can be often an issue. But there's more. If you read VDSM code before sleeping, as many of you probably do, you may be noticed that there is even one more constant, block size 1, which is equal to 1. And this is just internal VDSM constant, which is used for cases when we cannot detect the block size. As Neil said, for example, in the case of NFS, we are not able to detect the block size of underlying storage. What we do in such cases, we just use requested block size without any validation if there is any such request. And if the request is to detect the block size automatically, we fall back to 512 bytes just for keeping backward compatibility. In the previous versions, the alignment and block size were fixed, constant, hardcoded in the code. So there was no question about what the alignment is. But when we now can change the block size, we need to compute the alignment. And the alignment is determined beside block size by maximum number of hosts, which is configurable parameter for storages with 512 bytes. We still use the old constant of 2,000 nodes, but to have the alignment of 1 megabyte also for 4K storage. So for 4K storage, we now use the default of 250 nodes. So if you are going to use 4K storage and you are going to use more than 250 hosts, you need to configure maximum number of hosts on your setup. And once we compute the alignment, we store it into the metadata. As Snir already mentioned, we requested because of that new metadata format because we need to store block size and alignment. And here's an example of the metadata. We basically store the alignment and block size into storage domain metadata. So let me briefly recap what is the VDFM flow when you create storage domain. And this is roughly what you will see in VDSM logs if you will be investigating what's happening there. First, we detected the block size of underlying storage. Then we validated the requested size. If everything is OK, we compute the alignment. Now we are ready to store everything into the metadata. Then we created the directory structure as usual. And then we pass the alignment and block size to SunLog and initialize SunLog. So let's take a look how it works from engine point of view, which manages all the flows and hosts. First thing Engine will do is host activation. And during host activation, it will request VDSM about host capabilities and will store what given host supports or which block sizes for given storage domain it supports into the database. This is needed because when you create a storage domain, Engine will check if all the hosts support auto detection of the block size. And this is needed because we actually right now doesn't allow users to request or specify the block size of storage domain. And Engine always request VDSM to detect the block size. So it basically asks VDSM to create the storage domain with block size equal 0, which stands for auto detection. And Cloud VDSM create the storage domain. And once it's created, it requests VDSM again about information of newly created storage domain. And from information written from VDSM, it finds out what is the actual block size of the storage domain and stores it into the DB. OK, what happens if any of the hosts doesn't support auto detection? In such cases, we fall back to all behavior and we will request, we will skip the auto detection and will request directly create storage domain with 512 bytes. So if it happens to you that you have a couple of hosts with new VDSM, but there is some old hosts with old VDSM which doesn't support auto detection and you will try to create a storage domain on 4k, it will fail because it will request, Engine will request, creating of storage domain with 512 bytes and VDSM will detect that actual storage is actually 4k and you will end up with following exception. So if you can remember this exception because at least in the past it was the main source of confusion when people tried to use it. And it basically means that one of your hosts doesn't support auto detection and you, in the best case, should upgrade to the recent VDSM version. If not, it is not possible. You have to at least enable it manually. So this leads me to the troubleshooting section where I'd like to give you some hints what to do. If something goes wrong when you are creating storage domain. So here's a couple of questions you can ask yourself during the process. So first, I would really suggest to check if all hosts support auto detection. You can check it easily by calling VDSM client hosts get capabilities and you should see that it supports auto detection and also 4k in case of Gloucester. And then you should check if the storage domain metadata is correct, basically on case of Gloucester which is file based, you can just cut the file, check that the metadata version is number five and block size is what you requested. If this is okay, you can check if the engine really asked the VDSM to detect the block size. So you can grab the VDSM log for create storage domain command and check that the block size is equal to zero. If this is true, you can check what VDSM actually detected. For this, you need to enable debug level and you should check that the VDSM really detected the block size of 4k. If everything is okay, it's time to check the engine part and first, you can check if the engine recorded correctly the host capabilities. The output should be very similar to what you saw when I showed you the VDSM host get capabilities. The same information should be recorded on engine side in the database and it's stored in VDS table and you should probably select only host you are interested in. And then you should check what the engine stored for newly created storage domain. This is again in the database in table storage domain static and as you can see, you should see the expected block sizes are. So this is roughly all and now the funny part. I'm really sorry, originally we intended to do representation from my laptop as I have prepared demo here but I have some issues with graphics but thanks to the chairman, I was able at least to boot to graphical mode. So we will try to connect now my laptop and if we succeed, I can show you short demo. Okay, so maybe we can show before the talk, I did a recording of the demo so we can show you the recording of the demo instead of the live demo because anyway, we are slowly running out of the time so it would be easy to run the recording of the demo. So just a minute, I will copy to the USB. So here you can see it's roughly goes through the same commands. Sure, in troubleshooting, so here we call host capabilities and now you can see that for example, Gluster supports 4K and auto detection, the same for local FS while NFS doesn't support it. Now, we try to create new domain from user point of view, there's nothing changed, you just try to create new domain as usual and there's any change in the UI. So it just should show that it works in also on 4K storage. So now I will grab the VDSM log to check that the engine really queried VDSM to detect the block size. Yeah, and it's here, the block size equals zero. So it engine asked VDSM to detect the block size and now let's see what VDSM actually detected. It, yeah, so, and it follows the unit to enable debug log for this and here you can see what Nero spoke about that we first try to work one byte and 512 and then 4K and finally find out that the block size of the storage is 4K. So in the meantime, the new storage domain was successfully created and we can check the engine database, what it stores are and here as you can see, similar output to VDSM capabilities for Glaster, it supports 4K and auto detection and we also checked that newly created the storage domain has correct block size and it's 4K. So in this case, everything worked fine and we are happy and have a new storage domain with 4K block size. So I think that's all. Thanks for your attentions and other any questions. So the question is if we can use 4K without Glaster. Yes, well, you can use it with local FS storage. It was available, I think in 436 or 5% like this and on NFS we cannot use it. We always fall back to 512 because there are no requirement and on block storage, it's not enabled yet. Like we have all the infrastructure, the storage domain format, all the code is ready. We just need to fix the few parts that access block storage to use the actual block storage size and of course get the block size from the storage. In this case, there's no need to detect. We just read some values in CFS and we have everything. Any other question? The question is if the environment has to be homogeneous or if we can mix 4K with 512? You can mix. You can have different kind of storage in a vermet. 4K and 512 doesn't matter. But all the hosts, if you have 4K domain, you need all the hosts must run newer enough version to use the storage because in Ovid, all the hosts are connected to all storage. So in one DC, all the hosts should have the capability and then you can create 4K domain on one with one storage and on another storage, 512 domain. Yes, domain must be homogeneous. You cannot mix block sizes. Any more questions? If no, thanks for your attention again.


The Anchor Hawking Glass Corporation brings you Crime Photographer. Gethelbert, did you hear about the latest crime wave? What crime wave, Casey? It's a series of crimes that occur regularly every week. What's so unusual about that? Well, for one thing, every one of these crimes is solved in exactly half an hour. Gosh. Do they have any idea who's responsible? Why, sure. It's Crime Photographer, brought to you each week by Anchor Hawking. The most famous name in glass. Ladies and gentlemen, this is Tony Marvin. Every week at this time, the Anchor Hawking Glass Corporation of Lancaster, Ohio, and its more than 10,000 employees, bring you another adventure of Casey Crime Photographer. Ace Cameraman, who covers the crime news of a great city. Written by Alonzo Dean Cole. Our adventure for tonight, are quitted. Opposing attorneys, witnesses, spectators, and the accused step into attention as the jurors file into their box. Then the foreman is summoned to state the verdict. We, the jury, find the defendant not guilty. I told you to be that way. Well, you didn't have to tell me, Casey. I knew. Quiet, please. Quiet. Judge Lucas will deliver a few remarks. He always does. Quiet. I hope they're very few because I want to get to a telephone. Ladies and gentlemen of the jury, this court thanks you for bringing in a verdict that is all together in accord with the evidence that was presented to you. And similar thanks is accorded to the defendant's attorney, Mr. Freeman, for his presentation of his case. Thank you, Your Honor. Nuts. Freeman's a louse. You can say that again. But for the police officer who has figured so prominently in this case, the court has nothing but censure. Now it comes, Annie. Mm-hmm. Detective Ryan, evidence has shown that you deliberately and with malicious intent committed an unprovoked assault upon the defendant for the purpose of obtaining the confession that he here repudiated. That isn't so, Your Honor.  Quiet. How can a man be quiet when he's playing for doing his duty? That guy tried to escape, but I put him under arrest. He fought me in the house of dawn. Bayliff, reserve order in this court. Mike Ryan was sure to blow his top under that woman. And I don't... And I beg to call its pardon. Detective Ryan, it is in the power of the court to impose a penalty upon you for your disgraceful outburst. But in view of your apology, I refrain. I shall however recommend to your superiors that you be called to answer for your conduct in all phases of this case. Prison at the bar, Leonard Waldo, you stand acquitted, you are hereby discharged from custody. Thanks, Judge. Ladies and gentlemen of the jury, you are discharged. Court adjourned. Now I get to a phone and give the city desk the stolen. Yeah, I'll stay here. I didn't get some pictures. Okay, I'll meet you in the car. Okay, honey. Mr. Allison. Thanks. I just wanted you to turn around so I could get a shot at. I got it all right. Thank you. What did you want a picture of me? You were the complaining witness in this case. And since this man's been acquitted, I never expect to see that property again.  I couldn't be positive. He was the man I surprised in front of my safe that night. And one must be positive. But you originally identified him as the guy? I said then he strongly resembled the burglar, as I said it again today. I never said more than that. Excuse me, I want to say a word to the assistant district attorney. Yeah, sure. Hey, Freeman. Hello, Casey. Would you and your lucky client look happy for the camera? Yes, sir. Thanks, I got you. But what did you mean by lucky client? This lad was innocent as a newborn babe. Yeah, you just heard the jury and the judge agree on that, Casey. Sure, Lenny. I heard. I still say you're quite a lawyer, Freeman. Say, look ahead. Excuse me, paper guy's a naturally cynical Lenny. And Casey's right about you having a good lawyer. Yeah, you look good one all right. Huh? Oh, Officer Ryan. Yeah. Hello, Mike. Hello, Casey. I hope there's no hard feelings, Mike. You know there's nothing personal. What I did to you on the witness stand, it was all part of the game.  Take it easy, Mike. I am taking it easy, Casey. I'm not going to blow my top again. I'm just telling this slick mouthpiece I think he's a crooked louse.   I should let you have it right now, but, well, I won't. That's all. So long, Casey. So long, Mike. You're going to let him get away with that, Freeman? No. And Ryan... Say, you two guys aren't gonna... Keep out of this, Casey. Hey, flat foot. What? We're going to tell you a few things, copper. Oh, yeah? Freeman, you're supposed to have some brains. Big Mike Ryan is dynamite when he gets started. Ryan, my client and I will let you off easy. But since you've decided to be nasty, we'll see that you face not only departmental charges for manhandling a prisoner, we'll slap a civil suit on you for damages, resulting from assault and battery. You're not going to do that, Freeman.   Mike! Mike! Mike! Let go of me, Casey!   Hold him! Mike, hold him!  Okay, take your hands off me. I promise not to sock them. What's going on here? Oh, hello, Sergeant. Nothing's going on. Nothing at all. Casey's made a slight understatement, Sergeant. Officer Ryan just tried to attack my client and me. It was a deliberately provoked attack, Sergeant. I was leaving the room hall in my temper, Sergeant. When these two came... Okay, Mike. I'll make no report on it to add to your other troubles. Other troubles? Yeah. Commissioner sent me here for you. You got to report at his office right away. Oh, well, that means... Judge Lucas just talked to him over the phone. You can guess what it means. I'm sorry, Ryan. Yeah. Yeah. Okay, Sergeant. Let's go. So long, ex-copper. You're going to miss that bad year. Listen while low on Freeman. I'm going to get you two for this. Just remember that. Gentlemen, you're witnesses to that man's threats. Yeah, Freeman. And Mike Ryan's not the only one who'd like to take a poke at you, too. Hey, Walter, serve two more bottles of beer to these gentlemen. And bring up some more lemons. This is the lemon seasoning. Now to get back to what you and Casey was relating to me, Miss Williams. What did the commissioner do to Big Mike Ryan? Suspended him. Yeah? Yeah, and it's lousy. Mike's a swell cop. He's got his swell record, too. You don't think he beat up that Lenny Waldo in order to get a confession, huh, Casey? Definitely not. In my book, the whole thing happened just like Mike said it did. I forgot the beginning of this case. It happened over six months ago, didn't it? Shortly after Christmas, Ethelbert, this Robert Alliston, who's a wholesale diamond merchant, went to his office after hours with a friend and walked in on a safecracker. Well, a burglar blackjacked him and made a getaway with around $100,000 worth of precious stones. Alliston's friend got socked before he had a good look at the guy, but Alliston himself described him to the cops and the description fit Lenny Waldo, who, of course, has a long record for safecracking. Mike Ryan was one of the dicks assigned to look for Waldo. He found him. Waldo tried to make a break and there was quite a fight. Waldo came off second best. When Waldo yelled uncle, he spotted a confession along with it. Which he later affirmed in writing. Yeah, but before the trial, Dan Freeman, his lawyer, smuggled a camera into the jail and got some pictures of Waldo's bruises, showed the pictures in court, and created his confession, saying that he'd been beaten into it by Officer Ryan. Well, Alliston, who was the only person who could definitely place Waldo at the scene of the burglary, wouldn't make a positive identification. He's one of those ultra-careful people. Anyway, the whole case against Waldo blew up when Freeman got Mike Ryan's goat during cross-examination. And Ryan looked like the criminal instead of Waldo. There was no direct evidence. None of the stolen gems had been found in the man's possession. Oh, the insurance companies are holding the bag. And if they try to renege it, won't hurt Alliston much. He inherited a couple of million about a month after the robbery. He did? Yeah. A rich uncle of his died. Gee, I've always wished for a rich uncle in bad health. So have we all. Well, now the only one with any trouble on his hands is poor Mike Ryan. Casey, Freeman and Waldo threatened to press charges against Ryan to substitute civil action for damages. Oh, that was just bluff, Annie. Well, they were pretty sore at him from what you've told me. And he was pretty sore at them. I'm not sure that... All right, excuse me. There's a bar for Annie. Look, I'll bet you that Mike will be back on duty in a week. And Waldo and Freeman will go... It's for you, Casey.  Huh? Oh, silly desk. Give it to me. Hello, Burke. Yes, I'm here again. What? Glybers Cafe? Yes, sure I know where the place is. What? Wait a minute. Say that again, Burke. Okay, we'll get right over there. Hey, what is it, Casey? Dan Freeman and Lenny Waldo have just been shot to death, Annie. Shot? And Mike Ryan's accused of the murders. Tomorrow, all over America, cool frosty drinks will be poured from radiant sunburst crystal pictures into sparkling sunburst crystal tumblers. The radiance of this brand new kind of anchor-hawking crystal can be compared to a finely cut diamond. It's beauty to the rarest hand-cut crystal. Yet sunburst prices are incredibly low. Now, here are just a few examples. Sunburst crystal glasses for fruit juice are only 5 cents a piece. Table tumblers, 2 for 15. Big oversized glasses for ice drinks, only 10 cents each. And to top it all, a magnificent 2 quart pitcher costs only 50 cents. Now, you'd expect to find crystal as beautiful as this, only in a jewelry store. But as a matter of fact, all next week, the windows and counters of the retail stores of America will feature brilliant displays of sunburst crystal, priced from 5 cents up, slightly more in distant cities. Now, you'll recognize sunburst immediately by its unique sunburst design. So look for it, ask for it. Sunburst crystal, a product of anchor-hawking. The most famous name in glass. Casey, it isn't pleasant for me to tag another cop for murder, but this job spells Mike Ryan all the way. But we got on him, Logan. Yeah, tell us what happened, Captain. Well, Glyber's Cafe here was a regular hangout for Freeman, Miss Williams. After he won a case, he usually brought his client here for a celebration. Yeah, I know that. So did Ryan know it, Casey. There was a scene she'd find Freeman and Waldo together here tonight at Freeman's regular table, which is in line with that window there. You mean the two men were shot from that window? Yeah, opens in a dark alley. Ryan took two quick shots apiece at Freeman and Waldo, scored clean hits, and then made his getaway through the alley. Did anyone see Ryan do the shooting? No, but he left convincing proof that he was the killer. Proof? Look at this. Gold fountain pen. With his name engraved on it. Inspector Mulcahy gave it to Ryan a couple of years ago for being a top-notch cop. What did you find it, Logan? The alley. A few yards from that window where it had fallen from Ryan's pocket. Someone may have lifted the thing from Mike and planted it there, you know? I'd like to believe that, Casey, but... Ryan was seen in this neighborhood tonight. He was? Only a few blocks from here, Miss Williams. That guy lives on the other side of town and he was under suspension, so no duty could have brought him here. Well, it's hard to picture Mike sneaking through a dark alley like a rat and shooting two guys in cold blood. He was awful sore, Casey, and he has a rotten temper. Well, it's an open quick temper. It gets red hot in a few seconds and cools off almost as fast.  Your guys found him yet? Oh, but they'll be bringing him in pretty soon. I'm going back to headquarters and wait until they do. You mind if I stick along with you? Come on. Thanks. Annie, take these exposed films back to the office for me, will you, honey? Yes, Casey. I'll meet you there later. Now I want to hear what Mike Ryan has to say. I swear I didn't do it, Captain. I didn't know a thing about it until I went home and found Sergeant Flanagan waiting there for me. What are you doing near Glyber's Cafe just before the shooting, Ryan? I explained that to the sergeant, sir. I want to hear it. Well, okay. I got a phone call at my home tonight from a guy who wouldn't give his name. He said he'd give me a tip on the Weinstein robbery last week. If I'd meet him on Elder Street between Lexington and Grove at half past 10. Now, you've gotten that kind of call from Crook yourself, Captain. And so have you, Casey. You know that so, Logan. Keep out of this, Casey. Okay, sorry. So you're in the neighborhood, Ryan, only because you received this mysterious summons to be there, huh? Yes, and that's God's truth. Of course, your man showed up. Well, no, he didn't. I waited a while and then started back home. By way of the alley behind Glyber's Cafe. I didn't go near Glyber's. I walked in the other direction. You walked home, huh? Yes, good part of the way because I wanted to think.  What do you got to say about this fountain pen we found? Well, I lost it somewhere the day. I don't know where. Captain, I've been framed for this job. You've heard that excuse on plenty of Crook's yourself, haven't you? Yes, and sometimes it was true. One time in a thousand. Oh, yes, I know that. Captain, the boys gave me the dermal nitrate test right after they brought me in. It proved I haven't fired a gun for days. You know all the tricks, Ryan. You could beat the nitrate test. Yes, that's so. Well, where do we go from here, sir? I'm not going to confess to something I didn't do.  What's that? You heard me. I think Waldo told the truth in court. I think your story about his attempted escape was phony.   No man talks to me like that. Let me go, boys!    Kill, just as you did tonight. When something starts at temporary years boiling, all you can think of is murder, isn't it? I get it. And I fell for you, Rat Captain. I know I've got a tempter, but... I'm not a murderer. Take him away, boys. Let him sit in a cell awhile and think. Maybe he'll get wise to himself and tell the truth. Come on, Ryan. All right. Casey. Yeah, Mike? You're not a cop with a cop's way of thinking. Do you believe me? I think I do, Mike. Thanks. Let's go to that cell, boys. You... You really believe his story, Casey? Yeah. I think you do too, Logan. You were just putting on an act. I want to believe it because he's another cop. Which makes me unreliable. Mike's been a tough cop. A lot of crooks hate his insides. The quarrel in that courtroom today was pretty public. The news travels fast. Yeah. Mike's threats did provide us well set up for a frame. The perfect one for anyone who wanted Freeman and Waldo out of the way. Plenty of guys had it in for those two rats. Yeah. Yeah. Well, it's nearly midnight, Logan. I gotta get back to the office and check out and take Annie home. Yeah, after an hour of the blue note. Sure, that usually finishes up our day for us. Say, the only time you ever get a bright idea is when you're leaning against that bar. Will you stay there for a couple of hours tonight? Mike Ryan needs a break. Logan, if he's on the level as we're trying to believe he'll get his break, right guys do. And books written for children. Anyone ever tell you you had a grown-up brain? Well, I had sense enough not to become a lousy press photographer. So you became a lousy cop? Get out of here, I want to think. What with? Nuts to you. So long, mug. So long, sap. And nuts to you. Figure out who stole Ryan's fountain pen, Casey. Yeah, sure, that's the key to the whole thing, Annie. If the guy's been framed, but some dip might have let it slip out of his pocket he may have lost it on the street. Somebody picked it up. Yeah. As soon as you get that ice chop, Joe, go down in the cellar and bring up some more club soda. You hear me, Joe? Okay, apple boy. Oh, gee, I'm tired, Casey. I just had to mix up high bowls for a party of eight. Party of eight is a pretty young person to be drinking high bowls. Yeah. Huh? Nothing. Oh. Oh, I get it. It's not bad, not bad at all. It was terrible. Not that bad, Annie, no. Yeah, I guess you're right, Miss Williams. You two still puzzling over that murder? I'm getting nowhere, Effelbert. Say, ever since you come in I meant to tell you and forgot. I heard something funny tonight about them guys who was killed. What? I got talking here at the bar with a young fella I know. He's studying to be a lawyer. Bunny Shell, his name is. And he said he sat in on Waldo's trial for a while today, you know, to kind of pick up pointers. So? Well, so he said he was very much surprised that Dan Freeman didn't tell a jury about Waldo's alibi. Well, he would have. The rat had had an alibi. This young fella said he had a dandy. Oh, now, how did he know? Well, he'd seen Waldo a lot of times at a bowling alley where he goes to and he knows Waldo was there at the time he was supposed to be robbing that safe because Waldo picked a fight with him. Almost. Wait a minute, he can't be sure. Sure, he's sure. Well, okay, a good alibi would have gotten Waldo out of jail right after he got in. The guy Effelbert talked to was nuts. No, he ain't. He's always talking about nuts. No, he's a nice fella. Smart, too. He said he got so curious about why no alibi was mentioned at the trial, he went up to the bowling alley and checked. Guys who worked there told him Dan Freeman had come around there after Waldo was arrested and got him to sign papers about him being there at such and such a time. But they didn't hear from him again. Did he tell you what bowling alley it was? Yeah, the Acme on 11th Street. Acme, all right, Annie, come on. We're gonna do some checking there. Why? It may be Ryan's break. Oh, I don't get it. Annie, if this story is true, the whole thing is simple. I'll know who really killed those two guys tonight and why. Sit down, Mr. Casey. Thanks, Mr. Alliston. To what am I indebted for this visit at this hour in the morning? Are we alone here? My servants roll in bed, if that's what you mean. Why do you ask? I think you'd prefer to hear what I have to say alone. I have no idea of your meaning. The meaning is money. Money? Mm-hmm. Yours. A lot of it. Talk straight, Mr. Casey. Okay. I know that you killed Freeman and Waldo tonight and framed Mike Ryan for the job. You're mad. Am I? And you killed them, Alliston, because they were cutting themselves in on most of the dough you inherited from your uncle. Really? Uh-huh.  Around last Christmas time, you didn't have your uncle's millions. You needed dough. And you figured that a good way to get it was to steal from your own business.   The police were thoroughly satisfied. The robbery was no fake. Sure. You and Dan Freeman staged it so well. And your description of the thief was sure to result in Waldo's arrest. Uh, do I interest you? Go on. Well, to make it look good to the insurance companies, someone had to take a rap for a while. So Waldo was brought into the scheme. He made a confession that he'd robbed your safe after protecting himself with an alibi he never had to use. Your identification of him was just positive enough to hold him, but so unpositive that a jury would acquit him. But these characters double-crossed you. Now they could send you to jail for conniving in the theft of your own insured property. And they're putting the screws on tight now, right? You seem to be doing the talking. All right, I'll go on. When it seemed certain that they'd take most of your new insurance in blackmail, your new inheritance, you watched for a chance to double-cross them. Mike Ryan's threats in court gave you that chance. And when you helped me keep him from Sarking Freeman and Waldo, you slipped his fountain pen out of his pocket. Later, you made the phone call that brought him to the neighborhood of Glyver's Cafe. You did a smart job, Alaston. Almost smart enough. And how would you attempt to prove this wild theory? You've heard about the dermal nitrate test, haven't you? Dermal nitrate test? Yeah, that establishes whether a man has fired a gun recently. Oh, of course. Freeman and Waldo were shot less than four hours ago. The tests applied to the man who shot them would be conclusive. Shall I call the cops and ask them to test you? You said you came here for money.  Another one, just like Freeman and Waldo, only wiser. Purely out of curiosity, how much do you want? $100,000. You're most conservative. Which shall it be? The money or the cops? Neither. Why that gun? You're no smarter than Freeman and Waldo Casey.  And then what happens to you? This is my house. I surprise a prower in my home and shoot him as anyone has a right to do. And the shot I'll fire at you, Casey, will account for the result of any dermal nitrate test. So... Nice shooting, Logan. He knocked the gun right out of his hand. Oh, gee, wait. It's a long, Captain. I was afraid that Casey... This guy would only a shot Casey if I hadn't got him first. My pal, Annie. You were outside this window all the time, Captain. There, Alaston, I put the bracelets on you nice and easy. There isn't a bruise on you or a bump. I'm going to take a picture of him, Logan. Yeah, does it? Now no shyster lawyer will convince a jury that Alaston's confession before witnesses was gotten by way of anything but simple kindness. We'll join the crowd at the Blue Note in just a moment.

The most famous name in glass. Mike Ryan's back on the force, huh, Casey? Naturally, Ethelbert. And reinstated with apologies from the commissioner and Judge Lucas. There's a couple of things I still don't understand. Why did me telling you about Waldo's alibi give you the big idea... Ethelbert, when a crook gets into a jam, the first thing he pulls is an alibi. If he has one, that is. Well, Waldo had one. Yet neither he nor his lawyer ever even mentioned it. Oh, there had to be a reason. The only reason must be that he wanted to be thought guilty of that robbery. Which was covered by insurance. So they were trying to fool the insurance companies. Sure. And they'd have no point in doing that unless the insured person, Alliston, was in on the deal. And then knowing Alliston had inherited big dough, it was a cinch to figure the blackmail angle. Oh, sure, the whole thing was perfectly simple. Yeah, simplicity itself. Uh, Casey, there's a couple of things I still don't understand. But you mind explaining that again? Come on, Annie. This is where we came in. Good night, Ethelbert. Good night. Huh? A starring Stott's Cotsworth as Casey is brought to you each Thursday by the Anchor Hawking Glass Corporation. Makers of Fire King Oven Glass. Anchor Glass Containers. Anchor Caps and Closures. All products of Anchor Hawking. The most famous name in glass. Ron Gibson as Ethelbert. This is Tony Marvin saying good night for the Anchor Hawking Glass Corporation of Lancaster, Ohio, with offices in all principal cities of the United States and Canada. This is the biggest show in town. So stay tuned for exciting dramatizations on Rita's Digest radio edition, which follows immediately over most of these stations. This is Columbia Broadcasting Station.


Come back to Bradford City, so today we're mowing the pitch for the first time with a great strike, some small irrigation issues and environment issues, but we're getting there certainly and the pitch is getting more and more even day by day. So today we're completing the first cutch. Some other work we'll probably do this week is we'll probably apply an overseeding where we just seed into the areas where maybe birds have taken out seed or the irrigation has missed and from there then continue mowing and fertilising for the next few weeks. So going to plan at the moment, obviously Mother Nature has a big role to play and I look forward to giving you another update in the next couple of weeks.


Hello everybody, Andrew Meiske here with Dental L. So I was actually just talking to my students the other day. We had another online class. Our teeth whitening course has been open and there is an in-person component but we're just doing online classes right now. And you know we were all feeling pretty down you know because here we are at home we or you know they are so excited to start their own teeth whitening business.

departing on schedule we continue with the second act of suspense memo on medals interesting information about our military awards and decorations for almost the first half century of its existence from 1862 till 1904 the original design of the Medal of Honor was identical for both the Army and Navy a five pointed star with a large medallion in the center showing the goddess of wisdom Minerva warding off the figure of discord the Navy Medal of Honor hung suspended from its ribbon by a small anchor the Army Medal of Honor by an eagle resting on crossed cannons originally the ribbon was the same for both branches of service 13 vertical stripes of red and white top with a blue border in 1904 the army changed its medal to the present design with just the head profile of Minerva in the center of a smaller star backed with a green enamel laurel reef in 1913 the Navy changed its Medal of Honor service ribbon and in 1919 made an additional change resulting in the present-day design five white stars on a field of blue the Medal of Honor today as in the past remains the highest military decoration that can be earned by an American servicemen for devotion and valor above and beyond the call of duty it is an inspiring call to great sacrifice and dedication undimmed throughout the long years of our history as a free people and now starring Bartlett Robinson act two of the crowded

The truth between Israel and Hamas has been extended for two more days. The original truth had lasted four days. This comes after intense international pressure on Israel, which carried out a genocidal war on Gaza for 48 days. Now, this war is, of course, not over. Israeli officials have indicated their intent to continue the assault after the truce. But at least there will be a bit of a breather for the citizens of Gaza who have suffered this horrific assault. We go to Abdul for details about the truth and what is likely to happen in the future. A major global meet on TV was held recently. What were the conclusions? This is the daily debrief. These are your stories for the day. And before we go any further, if you're watching this on YouTube, please hit that subscribe button. Abdul, thank you so much for joining us. So a very significant development, the extension of the truce for two more days. So before we get into some of the details, could you actually tell us what the terms of this extension are and how did it come about? The term are by and large the same as it was for the previous truce for four days. Israel will release around 60 odd Palestinian prisoners. In exchange, Hamas is expected to release 20 for 10 on each day. Israeli captives from its captivity. Apart from that, the number of aid trucks will continue to be the same, pouring in inside the Gaza strip from Egyptian border. And so these are the basic conditions which have been the same. Of course it came about because of the pressure created by the global community and a large number of popular pressure basically, which we have seen through the demonstrations all across the world. Forst, even the US to basically exert its pressure on Israel to basically extend it. So Qatar and Egypt continue to be the mediators and because of their interventions, immediate interventions, this extension has come about. Abdul, of course, this is just a bit of a temporary solution, but could you also maybe give us an outline of how the first four days of the truce went, the number of people released, the humanitarian situation. Also, the details of the increase the extent of the attack or the impact of the Israeli offensive on Gaza. Well, for the first four days as it was agreed initially, Israel released around 150 Palestinians from its prison. Most of them were women and children. In exchange, Hamas released around 50 plus, 50 as per the deal, but additional captives which were basically requested by countries like Iran and other countries which have some influence on Hamas in some way or other. They also convinced Hamas to release additional prisoners. So they were also released. Israel allowed around 200 odd aid trucks to basically go to Gaza and that basically to some extent, of course, restored some of the civilian services which were completely destroyed in last 48 days, in more than 48 days bombings and ground offensive, particularly in northern Gaza. So some of the hospitals also received some fuel, but a large number of them remained because the amount which is allowed is not adequate to fulfill all the needs in the Gaza. As far as the overall destruction is concerned, if you see most of the civil infrastructure inside Gaza is completely destroyed. The universities in Gaza, the schools, the dispensaries, the bakeries which basically provide food, apart from that amusement parks like Gaza Zoo and most of them have completely gone. So we should remember that Gaza was already under blockade for more than 16 years, which basically had already had kind of destroyed the civil infrastructure there. It was all whatever was there was under pressure because of the huge population which lives in that small enclave, more than 2.3 million people. Over and above that the bombings have destroyed whatever was remaining there. So even if in the last four days there was some relief, some aid pouring in, some food, some medicine fuel going in, that was not enough to kind of even restore the 10 to 20% of the whatever is required and that has resulted into now reports coming from different parts of Gaza of disease outbreak and then there are still people trapped inside the ruins of the buildings which were basically bombed by Israel and during these four days around 150 people, basically bodies were recovered from inside those debris and there are more people, there are thousands of people missing and most of them are feared to be trapped inside those debris which were created due to the bombings on the residential areas by Israel for over almost close to one and a half month. So yeah, that was the overall condition. Right, Abdul, of course, we're talking about the extension of the truce but what really is the need of the hour is a ceasefire and of course like you said, the call from the streets around the world including in the global north as well that has been the call from relief agencies but statements from Israel do not seem to indicate that they're in any mood for anything more than a temporary truce at this point of time and it doesn't even look like some of these the global north countries, the biggest backer backers are in any mood to also push for a ceasefire despite the fact that close to 15,000 people have died. Exactly, if you see Israeli defense minister other officials have repeatedly said that they don't want to extend this truce beyond certain few days which basically will secure the release of the hostages whatever hostages Hamas has and that is their immediate target they want to release as many people as possible and once it is done they basically want to continue their offensive inside Gaza so their stated objective of kind of quote-unquote destroying Hamas's infrastructure in Gaza basically they want to fulfill it and this is also if you follow the Israeli politics, domestic politics there is a strong sentiment for that but also because the family of the hostages taken have also created some kind of pressure so the Israeli government was in a situation where it had to look for some ways to kind of make sure that maximum number of hostages are released so this temporary truce and the extension which it got which it has got and maybe it will be extended to two, three days more in future nobody knows basically is with the objective to kind of release as many hostages as possible and as if now there is a pressure of course on Israel from the global powers, from the US, from the European Union if you see the statements made in the last few days by some of the European leaders saying that there is a need of permanent peace, sorry permanent ceasefire in Gaza that pressure is there but whether that pressure will work or not whether that pressure will remain the way it is now it also depends on how Israel sees the overall situation in terms of hostages one and the second thing of course Israeli army was of course overstretched because the offensive went on for 48 days and it is not an easy fight for them so they also wanted to recuperate their forces to some extent and the truce is primarily seen as a strategic move to kind of provide some kind of break to the overstretched Israeli forces once their energy is restored it seems Israel is willing to continue the offensive and given the larger politics as we have discussed already there is no reason that Israel will the pressure will continue to be the same Abdul thank you so much for the analysis as further developments take place on the show we are consistently reported on humanity's fight against TB a disease which kills too many people even to this day the global south bears a brunt of this disease and while there has been a return to pre-pandemic levels of reporting of cases people still struggle to access medicines and care it's in this context of the annual union world conference on lung health was held from November 14th to 18th it brought together a diverse set of stakeholders to discuss issues around TB but the conference also brought out some interesting contradictions in this battle we go to Jyotsna Singh for more Jyotsna thank you so much for joining us like I said this TB is an issue we talk about very often on this show it's various dimensions and the effect it has on millions of lives very unfortunate and here we have another conference of course and I think many of these conferences are important because of course some of the topics they are discussed but also each of them presents its own version of challenges some of the questions that come up so maybe could you take us through this conference itself what is this conference why are we talking about it today yeah thanks happy to be back so the union conference is an annual conference which is organized in collaboration with various funders it can be civil society organizations some are actually big pharma companies or diagnostic companies they come together but also it provides a space to the TB community TB affected people and they fought for this space and that's why you can see them sitting on the table at times with the government and therefore in the union conference also and it discusses a lot of things which are relevant for TB for that particular year and so that's what we saw we saw a lot of presence of sessions related to science this time because many new scientific trials regarding medicines etc happened for example the end TB trial for drug resistant TB and how to shorten the time period for the medicines to be given to patients so that they can recover faster and better so there were those presentations that happened there was also a separate section of community connect where the TB survivors and the TB community itself they were present and they would hold their own sessions and the issues and advocacy and communications and also talking about their daily lives so these are the things that happened this time there was also a session and interesting presentations on the link between nutrition and TB and as many of us know that this year landmark study came out on TB which was conducted in Charkha in India which actually clearly showed that if you are able to provide good nutrition to the patients and their families then not only you have better outcomes for the patients but because family is also eating better the transmission of TB is less people because it's an infectious disease lesser number of people get infected by the TB affected population so there were these presentations and that's what it was very interesting to see Jyotsana but also I believe quite a few controversies which also say something about how some of these conferences are organized so maybe could you take us to that as well yes so I mean I participated in a few of the union conferences in the past this year I wasn't there but the issues remain the same and I think this is becoming very frustrating and challenging for the TB community and the activists to sort of deal with because you keep getting discriminated against again and again so for example one major major issue that emerged was denial of visas the conference was in Paris in France and a lot of TB survivors they were not given the visa and actually the reason given in some cases was that what if they go to the country and never come back and these are the people who had full funding they had some of them had letter from the union conference also so there is and this has happened in the past also and there is a demand that the conference management has to speak to the governments wherever they are organizing and it is a rotationary thing it gets organized across the world in various countries but they have to choose places which are far more accommodating for people for diversity and you cannot have such racist you know reasons for people not being able to attend in fact the main speaker for the final recession the keynote speaker who was a TB survivor could not get the visa and reach Paris so these were the major problems and the other thing which you see and again we have witnessed in the past is how the very use of the space the physical space and which is so discriminatory so where the community is given the boots to organize and put their own stuff to do their advocacy it is always towards the dead end of the entire space and not where the people would be passing so it's more like there is a space as if it's they are a different people and not within the science within the experts space where people discuss like big things right science and all so this kind of a discrimination is really problematic even the room where the activists and the survivors gather to talk and that was absolutely really far this time as well so these are some of the demands that the community is making that we got to be integrated everywhere we do not want tokenism and we are the ones who are the stakeholders we are not a separate entity so that so that is something and it becomes controversial every year and the union is not finding solutions the other thing was but it also provided a space to the activists to protest against some of the very high prices there was a huge protest during the opening session inaugural session where the activists went on the stage and the major demand this year with regard to pricing was bringing down the price of the diagnostics for the drug resistant TV so Seafit which has been it's a diagnostic company which was also one of the funders by the way and they had a session where also there was a protest during the union conference but they so they're the diagnostic the expert test as it is called it's very costly and of course they have the monopoly over it and Seafit has been taken over by Deneher this other corporation but so they the price was 10 dollars per test a few months ago they but the experts they have some researchers have calculated it should not be more than five dollars per test so there has been demand to reduce the price to half so it's time for five that slogan has been there for many many years the Seafit brought the prices down a little bit for multi drug resistant TV but for extreme drug resistant TV which is a much worse form of TV they have still not brought the price down so that was the demand that it has to come down to five because that corresponds to the production cost and it also involves reasonable profit for the company and there were a lot of protests and let's hope something happens because there was one good news at least this year earlier this time when Johnson and Johnson the company makes betakulin and they are not enforcing their secondary patents in countries in the world and that has happened because there has been pressure constantly on Johnson and Johnson on their pricing of the medicine and monopoly over the medicine so we hope that would happen in the space of diagnostics also so hopefully these protests that have happened will yield some results in the near future


Okay, so one thing I've enjoyed about working with the CG Center is the interdisciplinary nature of my work. So even though I'm answering a technical question around livestock production, I'm using lots of different approaches to answer that question, whether they're from social scientists, including gender or anthropology, or from a technical background. And just on this topic, I think it's very important that we don't box people into being either a technical scientist or a social scientist or any particular type of scientist. We can all use integrated approaches, including approaches on gender to strengthen our work.
