Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Microsoft wins FTC fight to buy Activision Blizzard
Halo was mostly all about single player and early multiplayer/local multiplayer but their online netcode has sucked since Blood Gulch. Lots of games do networking horribly, I have been in gamedev making networking and I hate most of what people do. The ones that have a clean natting, based on enet style reliable UDP channels, RakNet style punch are better (RakNet was good until Facebook bought it). It has come a long way but also fallen back. Valve source netcode (on github) is probably the best and you can check it out here. They started with the best in Quake networking, then to Source.

Porting SDL2 Game to the web, Emscripten tutorial
Probably not. It says Enet runs over UDP, which Web Browsers / WebAssembly / Emscripten don't provide. Web browsers / Emscripten provide TCP only (source). That, and Enet probably calls standard UNIX / Winsock functions, which Emscripten doesn't have. ENet would have to specifically support Emscripten as a target platform.

Game networking with QUIC
Are you familiar with enet ? It's a popular C library which implements optional reliability on top of UDP.

HTTP/3 becomes a standard, at last - Networking - Security
The other that is the base of most networking libs today is enet, one of the cleanest C networking libraries you will ever find. The RUDP and channels in it were very nice.

Making a multiplayer server
Inconsistencies can be prevented by ensuring the server handles all operations and does so in a given order, then transmits the results to clients. I wrote a little about this for my game Avoyd a long while ago. Clients (including a client running the server) send an edit request via reliable ordered UDP (e.g. using Enet, Raknet, Steam Networking etc.) and the server places these in a single queue then performs the edits and sends the results back also using reliable ordered UDP.

How I Taught the D Programming Language at a Russian University
I find this interesting. Vibe.d is async, but written in a sync fashion (in essence, the async is hidden in the i/o subsystem). For my class with grade-school students, I used enet (http://enet.bespin.org/) with a wrapper I wrote to automatically serialize messages.

what is the easiest way to add online multiplayer to a voxel game?
A popular simple low level open source reliable UDP library is ENet.

Speed Dreams needs you! (Call for devs)
-Improve the status of the Online Mode: This mode built with eNet, currently allows to create multiplayer races, but while it works acceptably well in a LAN, over the internet is unplayable presenting a huge lag, among other problems.

Subdomain.center – discover all subdomains for a domain
Getting a wildcard certificate from LE might be a better option, depending on how easy the extra bit of if plumbing is with your lab setup.
You need to use DNS based domain identification, and once you have a cert distribute it to all your services. The former can be automated using various common tools (look at https://github.com/joohoi/acme-dns, self-hosted unless you are only securing toys you don't really care about, if you self host DNS or your registrar doesn't have useful API access) or you can leave that as an every ~ten weeks manual job, the latter involves scripts to update you various services when a new certificate is available (either pushing from where you receive the certificate or picking up from elsewhere). I have a little VM that holds the couple of wildcard certificates (renewing them via DNS01 and acmedns on a separate machine so this one is impossible to see from the outside world), it pushes the new key and certificate out to other hosts (simple SSH to copy over then restart nginx/Apache/other).
Of course you may decide that the shin if your own CA is easier than setting all this up, as you can sign long lived certificates for yourself. I prefer this because I don't need to switch to something else if I decide to give friends/others access to something.

I've created a solution for managing internal domains, how do I selfhost this more?
As someone else said, it’s a huge pain to run your own dns services. However, if you want some separation, I recently saw https://github.com/joohoi/acme-dns

How do you deal with SSL certs management?
I have set up an acme-dns server to answer ACME DNS Challenges: https://github.com/joohoi/acme-dns

What is a good alternative if port 80 is blocked?
The DNS challenge can be easily automated using https://github.com/joohoi/acme-dns - you do need an IP you can run a DNS server on though.

Setting up ssl on AGH
If your server is not accessible over the internet, you can still use Let's Encrypt or ZeroSSL to get a certificate. You'll just need to set up a DNS Challenge for things to work. This is a little more complicated, but can work even if your DNS provider doesn't have an API. For example, I use Google Domains and Google DNS (not cloud DNS) for my DNS server, but I've got an instance of acme-dns running on VPS box that handles the DNS auth for me. It's how every machine on my local network has valid certificates - but I annoyingly need to renew them every 90 days.
-
Did Manjaro just forget to renew the SSL certificate?
It's a bit more involved, but you can set up wildcard certificates to update automatically. Certbot has some pre-made plugins for this for several DNS providers. If yours is not on that list, there's a tool called acme-dns which is a minimal DNS server you can run on your server and delegate _acme-challenge.yourdomain.com to. If you don't want to run that on your own, you can also use the publicly hosted server/API for it.
-
Reverse proxy for internally hosted services
In case you're not already familiar with it: one thing I'd recommend is using https://github.com/joohoi/acme-dns to obtain the certificates. You basically just point the subdomain you need wildcard certs for at that DNS server (a one time thing, ie you don't have to do this every three months), and the related tool https://github.com/acme-dns/acme-dns-client can get the certificates in a nice, automated, way without you ever having to expose the private reverse proxy to the Internet.
