Fellow hacker Arun Isaac introduces ccwl, a #Guile tool to describe “workflows” and to compile them to CWL:

“Austrian DSB: EU-US data transfers to Google Analytics illegal”
https://noyb.eu/en/austrian-dsb-eu-us-data-transfers-google-analytics-illegal

“In a groundbreaking decision, the Austrian Data Protection Authority (…) has decided on a model case by noyb that the continuous use of Google Analytics violates the GDPR.”

Though… an EU-hosted alternative would be a comparable threat to privacy, just on EU soil.

Did you know? #GTK 4 depends on mozjs (via polkit), Rust (via mozjs, librsvg, etc.), and Qt (via GStreamer)!

@ekaitz_zarraga I’ll recap everything in a blog post Real Soon Now, but in the meantime you can look at https://issues.guix.gnu.org/49169 and related messages.

@ekaitz_zarraga @janneke Sure, experience reports are always insightful IMO. It helps understand the concrete barriers one has to overcome.

Deadline is Dec. 20th.

@ekaitz_zarraga I respectfully think you’re wrong here. :-)

I for one would love to hear about things you’ve achieved and learned around RISC-V, Guile, Mes, and all that.

I’m bitter because a paper of mine about security aspects of #Guix was rejected from a hi-profile conference. Here are my favorite bits from the reviews:

“Readers often skip background sections. I would not put the essential information about Guix in the background section”
“The reproducibility of the study is not possible”
“The data and code is not published.” 👍

Hey reviewers, anonymity doesn’t mean you can skip your homework!

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. 🙂

@ekaitz_zarraga I need a bigger hard disk. ;-)

Seriously though, it’s the story of two good’ol integer overflow bugs:

I managed to build my #LaTeX/Beamer slides with #Guix’s “modular TeX Live”—i.e., tiny individual packages as opposed to the huge monolithic ‘texlive’ package. Here’s the manifest:

I was invited to participate in a 4-day all-Zoom event and the organizers kindly let me host my session on a BigBlueButton instance instead, which ran smoothly as always.

I wish they’d taken the opportunity to move other sessions to BBB, but that’s a start, and much appreciated!

@ekaitz_zarraga Ah! If man-db is not in the same profile, then MANPATH is unset (because Guix cannot guess you need it), so ‘man’ doesn’t find the man page. HTH!

If you’re wondering why things feel faster today, that’s probably because the man-db hook is gone:

#Guix

@ekaitz_zarraga While looking into that code I found that the ‘guix shell’ cache would not be cleaned up as I described in some cases, oops!

@ekaitz_zarraga Hi! ‘guix shell’ periodically removes old “garbage collector roots” when you run it, where “old” currently means “not accessed since one week or more”.

You can forcefully remove them with ‘rm -rf ~/.cache/guix/profiles’.
