It’s documented in the wiki, they are called VCS packages, and it’s not the usual, they work a bit differently: https://wiki.archlinux.org/title/VCS_package_guidelines

You can see in this instance, that it skips the sha checking for upstream source, in line 15 of the PKGBUILD it says ‘SKIP’: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=hyprspace-git#n15

sha1sums parameter is documented in the wiki: https://wiki.archlinux.org/title/PKGBUILD#sha1sums

In the PKGBUILD file you can list sources (line 12,13) and their respective checksums (line 14,15). In this PKGBUILD there are 2 sources: the first is the systemd unit file, it’s coming from the package’s AUR repo, not from upstream, you can see its checksum. The second source is the actual source, and you can see, it’s checksum is ‘SKIP’ so it shouldn’t be checked.

With these kind of packages you can’t get notified if there is an update available, but if you install it again with your favorite AUR helper it would update itself for the latest version. It calculates version number from the latest commit hash, before building and installing, so if that is the same it won’t update again.

It was 33rd in 2010:

In November 2010, the Air Force Research Laboratory created a powerful supercomputer, nicknamed the “Condor Cluster”, by connecting together 1,760 consoles with 168 GPUs and 84 coordinating servers in a parallel array capable of 500 trillion floating-point operations per second (500 TFLOPS). As built, the Condor Cluster was the 33rd largest supercomputer in the world and was used to analyze high definition satellite imagery at a cost of only one tenth that of a traditional supercomputer.

Good video… but a nearly 2 minute ad in a 5 minute video? ~40% ad? Wow.

Not counting yt ads as I block them. I’m considering starting to use sponsorblock, this is too much.

Nix just calls the *.nix files, it’s still go under the hood. PKGBUILD is similar to the flake.nix and package.nix files to me, but I have no experience with nix.

There is already a PR about fixing the low contrast: https://github.com/openstreetmap/openstreetmap-website/pull/5325

I think that may be an American thing. I’ve never seen one here in Europe.

I can see it without login

My general view is similar, yaml is better if it should be written by humans, json is better if it should be written and read only by a machine. but hyprspace uses json for configuration, so I don’t really understand cellardoor’s comment

They are users not developers. An academic or civil engineer who uses a CFD simulator usually has not enough programming knowledge develop such a complex application. The employer has not enough funds to pay for developers (see, they use a pirated software). Paying for developers is still more expensive than buying an already developed product.

Just look at the state of FOSS CAD software. There are some, but they are very-very limited compared to proprietary alternatives. Most people don’t care, they just want to get the work done. Not everyone is a programmer, even if it looks like that from our lemmy bubble.

In the Register article they didn’t copied from the source that the scientists were from Egypt.

Flow3D has different academic and research licenses: https://www.flow3d.com/academic-program/

• There is a free research license available, but it’s only for 4 months. It’s short, researches can take much longer than that.
• There is a free teaching license, but it can have limitations for using the software outside education. It may be forbidden to use outside classes, so it’s possible that they had a teaching license, but they couldn’t use that for research?
• There are licenses for full departments, but it’s available for selected countries only.

It’s strange that they went after these scientists. In 2nd and 3rd word countries software privacy for work is still common. Everything is cheaper, but software prices are the same as in the US, so they pay relatively more for the same tool. I found that a normal license for Flow 3D can cost USD 100k. According to a quick search civil engineers get USD 2000 yearly in Egypt.

Usually American software companies don’t really care about piracy by individuals in these countries. The rationale is that it’s better for them if they use their software without payment instead of using a software from another vendor without payment. They go after bigger companies, at least that’s my experience.

That’s why this story is strange to me, or at least something else should be behind it.

# At least you can have comments unlike in json. Who need comments in a config file anyway.

Or port forwarding. You have to open a udp port for wireguard

AUR packages ending with"-git" or “-svn” always pull the latest commit from source. The version number means that was the last time the packager had to change something on the PKGBUILD script, not the actual version which would be installed.

Where should I look? Where were these talks? I’m interested.

Edit: I found the whitepaper about hole punching: https://research.protocol.ai/publications/decentralized-hole-punching/

It says it connects to a “Hole Punch Coordination (DCUtR - Direct Connection Upgrade through Relay)”. So for NAT traversal to work, you need a third party, this relay. As I expected. I guess you can self host this, but than you could just host a wireguard server. I guess if you are on a locked down network where you cannot connect to any relay (e.g. how the Chinese Great Firewall works technically they could block it) you can’t initiate a connection behind a NAT.

Nonetheless it seems interesting, but no magic here. Maybe the big difference that the relay servers are distributed, so no central authority to block easily.

Interesting, it’s on AUR, I will try it.

So it doesn’t need any port forwarding, and works on CGNAT? How the “NAT hole punching” works? Both clients connect to something on IPFS?

Afaik, for DHT with torrent, clients need to know at least one tracker, what is the “tracker” here? Something on IPFS? Who am I sending my IP addresses?

How much overhead does this add to speed? I love with Wireguard, that it’s barely noticeable, really close to p2p speeds, OpenVPN was awful in this regard.

How do you know your assumptions are correct? It didn’t sound that way to me. “Any idea” sounds like they have no idea, but they use the more rare init system.

I pointed in the correct direction, and it seems like they didn’t search for it, as it wasn’t in some super hidden place. The note was for future reference, as I won’t be there to search for them in the future, and life is too short for waiting for easy answers.

I just typed “openrc” on the search box on the issues page. People on the internet forget nowadays that you can search, and it’s quicker than waiting for an answer…

If you need a GUI tool, I use Input remapper: https://github.com/sezanzeb/input-remapper Very straightforward to set it up, it’s available via dnf.

Fellow lemming hirak99 has a tool for that as well which should have better performance, but no GUI: https://github.com/hirak99/keyshift no prebuilt for Fedora unfortunately

You will loose your mind, but wayland version of xev is called wev.

It’s available in a lot of distros: https://pkgs.org/download/wev

Police was not expecting this?

I used to work in an office building next to a big football stadium, and on days of international matches every road was closed and the hooligans were separated by cordons, it was carefully arranged how the foreign fans could reach the stadium without bumping into local hooligans, mounted police were waiting nearby if something goes wrong.
