Rest assured, is not impacted by greenwashing!

"Imagine [...] being able to monitor oil and gas plants in remote locations to perform predictive maintenance"

This is a example usecase coming from their microshift project announcement: next.redhat.com/2022/01/19/int

Finally, I created the nix2container repository with a faster dockerTools.buildImage implementation.

@solene A drawback of using lists to set features is that it makes overriding harder to achieve (you need to manipulate a list).

But that's a detail and hardening services is a pretty nice stuff ;)

Good news for long-term source code preservation and support in #Guix!
👉 softwareheritage.org/2022/01/1

This grant will allow Timothy to further work on #Disarchive, the missing link between #SoftwareHeritage and the deployment tools such as #Guix. 👍

I actually can't believe these sentences!

"Instead of storing the data on-chain, NFTs instead contain a URL that points to the data. What surprised me about the standards was that there’s no hash commitment for the data located at the URL"

So, people would not spend money for images, but for URLs, (pointing to images that can be updated)...

Glad to see a line in one of my company doc!

Especially that i didn't write it myself ;)

"Introducing nix-casync, a more efficient way to store and substitute Nix store paths"

https://flokli.de/posts/2021-12-10-nix-casync-intro/

TL;DR: improving the Nix binary substitution by splitting the NAR archives in small chunks.

This distribution mechanism should decrease the amount of data we need to download each time a small input hash changed for a given derivation.

@erictapen Yes! Sorry I shouldn't have ping you in my answer.

And to be sure, i tried your method on gremlin-console (a prebuilt jar from nixpkgs) and it worked: there is a log4j jar in the gremlin-console store path.

Looks like this whole #log4j debacle is going to be hard to address due to Java practices consisting in shipping binaries (jars) of unknown provenance.

Glad the one in #Guix is built from source, and now fixed:
git.savannah.gnu.org/cgit/guix

@aurita @erictapen @musicmatze Unfortunately, this doesn't work when we fetch prebuilt jars instead of building them (gremlin-console for instance).

Note this would however work with since they build everything from sources.

Looking for an opportunity to NixInfect 💉 your company?

docker build -f default.nix .

A maintainer is experimenting to build Nix derivations with , a famous container build tool.

@Ninjatrappeur I started like that, and at 35, I put my desktop on wheels to be able to easily change the distance between my feet and the wood stove!

btw, nice outdoor view;)

@civodul Thx! And I'm glad this is useful for Guix!

Hey ! I've just noticed that today's date was a palyndrome ! Happy 20211202 everyone ! : 3

@lewo There’s a CI job continuously “disarchiving” and populating the database:
lists.gnu.org/archive/html/gui

Would be nice if this could be useful to NixOS!

Perhaps it could be maintained by SWH longer-term—we’ll see.

Just finished presenting how #SoftwareHeritage helps #Guix achieve reproducible deployment, including the latest advances around #Disarchive.

Great to have the opportunity to share with this fine audience!

And of course, 👍 to Timothy, Simon, and everyone who made it happen in the first place. 🙂

@civodul Congrats!

Would be nice for to use Disarchive.

How do you fill disarchive.guix.gnu.org? Do you pull the json file?

(i'm actually wondering if NixOS could use your tarball metadata server :/)
