Thanks for notice, I think that this and The Microsoft-Dilemma - Europe as a Software Colony should be mandatory to study for #cvut and may it be even #cesnet IT captains. Exactly questions to resiliency to the temporal Internet connection lost and even possibility of hostilities after steering to total dependance on MS technologies have been part of my request for some analysis in the official CTU IT issues trackers. But all tickets have been closed by Mgr. Stanislav Kalina (Microsoft Technical Specialist in the Czech Technical University in Prague organization) as totally unfounded nonsense and FUD spread.

I am looking for an alternative without disruptive and distracting advertising that our students could use for a long time, and I am happy that we can test the alternative you provide. I had become angry many times when I needed to check/scan my or my colleague's previous lecture recording to follow with the next one fluently and have been forced to wait for three or five seconds after three seekings from the four. Thanks for your PeerTube setup. We will see if it will be appreciated by our students and the worldwide community, which uses #riscv for teaching. But in the long term, solutions backed by some stronger provider as is #cesnet are necessary for some wider use. I have seen that foreign universities use https://en.wikipedia.org/wiki/Kaltura, but may it be PeerTube can prove to be better choice.

@M4RSarK Have CTU #cvut IT experts considered alternatives to moving to Microsoft Entra ID next week? As I understand, MS Azure would be the authoritative source of all our university identities, and there (hopefully) will be some slave copy of Active Directory on our university servers. Unfortunately, my official ticket has been closed with the statement that information about the security system solution and contracts with Microsoft are confidential. Experts have taught me in the past that each system based on security through obscurity is only a temporal solution and usually indicates a bad design. Have you consulted #cesnet, RedHat, SUSE, CZ.nic? It seems, according to #lwn article Lessons from open source in the Mexican government, that Mexico is more aware of the potential risk to depend on the systems controlled by other country (one not-so-old example). I am not expert for security and it is not interesting area for me, I have already quite large portfolio, but I am so frightened that I would ask people form RedHat, SUSE, CZ.nic to start to gain some basic knowledge in the field to know what are the alternatives. If somebody reads this and have experience with alternatives for authentication system for organization with 20k+ personal accounts and lot of roles (I do not know the number, again classified as confidential, even that do not know any reason), then I would be happy for reply.

@M4RSarK Excuse me, but you are at charge at FEE CTU IT ( #cvut ), so why is the only public way (with tracked history) to communicate with our faculty senate over Discord and it is advertised at senate candidates debates, why we will be most likely forced to switch to Microsoft two-factor authentication, e-mail etc. I know that these things are not so simple, but at COVID outbreak, one our admins (Daniel Vecerka) set up BigBlueButton instance on our servers in less that two weeks and final integration with courses schedules from study system database, recording, recording processing etc. is far more advanced then what I have seen in Teams which are pushed to us for communication by top management. Same for the PR department which feeds Twitter/X, YouTube etc. I know that it is hard, but we should have FEDIVERSE at social.cvut.cz, we should have Discourse etc… I use for my projects and subjects Debian/GNU/Linux for decades for decades and no closed tool at all. I contribute to whole world to have alternative for computer architectures teaching on open architecture (RISC-V) with open tools https://comparch.edu.cvut.cz/ and with open lectures sources. My groups of students contributes to open system for control systems and theory education and may be even devices design (pysimCoder), yes it is toy still, but used worldwide and gaining momentum. But at our department it is downplayed and I can expect that in some time there would be no lab with computers and enough Ethernet connections for embedded targets to run the environment directly. I have been forbidden to participate in the discussion about the future of K2, other labs, rooms where I work with my students. So I suggest even to you to approach downstairs from the clouds and global world dreams and solutions and solve manageable problems at reachable level. Discuss with CTU FEE PR, that we should start to have alternative to AI and mighty controlled channels, we should teach students basis which allows them to setup own systems, build own space grade controller (our RTEMS BSP is used by Airbus Defense and Space USA, my former diploma students contributes to ESA CPU desig, so the claim is exaggerated only a little) etc. OpenAlt has moved to local PeerTube instance vhsky.cz. Why am I forced to register and even pay to can check my own lectures on YouTube without advertisements when there is #cesnet which is paid from public money to provide support to Czech universities… and I can continue.
