I do not know the in's and out of ircv3. But we use matrix/elements for videocalls. Groupcalls. Screen and videosharing etc as well; Not just text chats. Beeing able to quickly search all of your chat history across all your channels and dm's are very nice. Not requiering a irc bouncer to recieve messages is essential.
Atleast for us having another vm among the thousands we host in our dc is not a huge cost, but i understand that is not the same for everyone.

Thank you for a detailed answer. We probably do not notice much of this problem yet, since we are in the low user count of 30-40 with mostly local channels.

Where I live in norway it is not like you could buy lunch either. People made lunch at home and took to school. Usualy a piece of bread and slice of brown cheese. May be different in huge schools.
And anyways if someone had forgot, the teachers had a backup solution, for free.

I have never tried that. We use it to share powerpoints in meetings or do troubleshooting together. Or I use it to do family video calls with the kids. Fps are never an issue. There are times where there are compression artifacts tho. Especially if someone have a bad or variable connection. On a buss or a train or similar.

In what way are matrix expencive? You do not have to self host it. You can just make an account on any public matrix server.

I do not know what you talk about. I use screen sharing and voice chat daily on elements with our own hosted matrix server.

Edit: i felt wrong saying "voice chat" what even is that. I make regular calls and video calls with screen sharing in elements ;)

Matrix+elements is very easy to selfhost in any homelab. works well enough for goverments. Federated and easy end to end encryption. And one can easily set up a web archive bridge forvarchiveable rooms.

That beeing said i still think IRC is the best for pure text chat.

Same in norway. You can also transfer some over to a new year. Or be paied out days. But you can not loose them.

I felt dirty! and broke so much shit when i had to implement NAT on networks in the mid 90's. Nowdays with ipv6 and getting rid of NAT is much more liberating. The difference is staggering!

• you do not need NAT any longer, firewall is the security, just like on ipv4, just less obscurity.
• you do not need dns views, to workaround NAT any more
• you do not need hairpin NAT to workaround NAT any more
• you do not need to renumber to resize a network. they are always /64, and the answer to how many hosts can it fit is: ALL of them!
• many ALG's will be unnecessary since there is not NAT.
• vpn's are easier, since it can be the same address both inside and outside the vpn, the firewall (or host even) enforces the encryption.
• vpn's are MUCH easier since you will have less rfc1918 collisions due to some other network using the rfc1918 of the vpn's network
• vpn's are MUCH MUCH easier since you will have less rfc1918 collisions due to you using the rfc1918 of the vpn partner network, to 1:1 nat a previous vpn network you collided with some months ago... ARGH!!!
• vpn are generally less required, heck i swear 95% of the time the VPN are just to workaround the NAT problem and the data is pointlessly double or triple encrypted.
• you can make more granular firewall rules (eg the spesific host, or network of the source address, instead of the whole enterprise's public ip) this is real tangible improved security, where any random machine in a network you do not control. do not automatically have openings into your own network.
• firewall objects can if it is suited easily use and depend on FQDN DNS objects when allowing traffic. reducing the need of coordinating firewall object ip address changes between 15 companies.
• firewall rules are easier, more readable, and much more predictable how they will work. All the hairpin nat, public to private nat, private to public nat for a thing that need a different public ip, 1:1 nat for a separate zone, NAT to a vpn or 50 (where 10 of them are 1:1 nat due to collisions, making you require 4 dns views of the same ip space!! ) very quickly gets messy and unreadable. this is probably the largest security benefit. just to reduce the complexity.
• much easier to get people to use dns, since nobody wants to remember ipv6 addresses :D
• nibbles in the ipv6 address can have meanings you assign to them, making the networks and structure both easy to remember and logically structured.
• aggregating routes becomes very easy if you design your network that way.
• firewall policies can become easier if you design your network that way.
• your routing tables is leaner and easier, and of a better consistency. We have 1 large public ipv6 prefix, but 25ish ipv4 prefixes of all kinds of various sizes.
• no need to spend $$ to buy even more ipv4 prefixes.
• no need to have spent hundreds of $$ on a new ipv4 prefix only to be unable to use them for over a year because you need to sanitize the addresses from all the reputation filters. and constantly hound geo ip database providers to update the new country of the prefix. (i am bitter,, can you tell..)
• did i mention no need to renumber since you need to grow the /24 to /23 due to to many hosts in a network ?
• did i mention no need to renumber 2 /24's to /25's to make space for that larger /23.
• you do not even need any ipv4 addresses any more, use a public NAT64 service, for outgoing. and for incoming just use one of the many free public ipv4 to ipv6 proxies for your services online. for a homelab i really like http://v4-frontend.netiter.com/ (go support them) But most large business l networks use cloudflare, or akamai
• since you do not need your ipv4 address space any more, you can ~~sell them for a profit $$$ ~~ return them to the RIR and give some address space to one of the thousands of companies struggling because they do not have any IPv4 : https://www.ripe.net/manage-ips-and-asns/ipv4/ipv4-waiting-list/
• much lower latency on ipv6, since you do not go across a cloud based ipv4 to ipv6 proxy in order to reach the service ;)

Now the greatest and best effect of ipv6 is none of the above. It is that with ipv6 we have a slim hope of reclaiming some of what made the Internet GREAT in the first place. When we all stood on equal footing. Anyone could host their own service. Now we are all vassals of the large companies that have made the common person into a CGNAT4444 using consumer mindlessly lapping up what the large company providers sees fit to provide us. with no way to even try to be a real and true part of the Internet. Fight the companies that want to make you a eyeball in their statistic, Set up your own IPv6 service on the Internet today !

So he did not enable the "Try proton on all games, even if not explicitly supported" in steam options. shakes head

I am always impressed by how randall can show a lot of detail in very VERY simple shapes. Eg the head rotation in this case.

But there are so very many games that do work. That those that do not, i can easily ignore.
