I've been looking this tool for years and it was there all the time: https://github.com/firecow/gitlab-ci-local

My workflow has been before:

1. Edit .gitlab-ci.yml without knowing what I'm actually doing.
2. git push
3. Hope for the best, fear for the worst.

It has been pretty difficult to learn it when I have to test every edit remotely and once I reach my quota wait for some weeks to continue.

And no, GitLab runner is not a solution:

1. I've never been able to successfully set it up.
2. It does not scale to multiple Gitlab instances easily.
3. Even if two former were somehow addressed I do not want to run random system daemons.

I.e. to summarize: A local Gitlab runner sucks. It sucks unimaginably hard.

Japan, national morning news show:

An uninterrupted 10 minute segment about a new train running on a line to a popular vacation spot.

A journalist spends most of the segment being absolutely DELIGHTED by every single feature of this tastefully designed train. She sits in every class of car, tries every seat feature, eats a curry in the dining car, enjoys the view out of panorama windows. Arrives rested and gives us a whirlwind tour of town.

This is how you change car culture.

Randomly noticed that one thing I was making noise about while ago is fixed in #Linux 6.10: you can now #BPF when CONFIG_MODULES=n. It was not my main goal to contribute, just make the issue visible, but there was also one of my patches in the final version (nice surprise because it was alien area in kernel for me).

The priority for me was to squeeze down the compilation time for testing/CI while still having up to date tracing capabilities.

People say me that #Kirchoff #EQ is great or even better than #FabFilter Pro-Q3 but...

Dynamic EQ is not a great tool for shaping transients as the filters are connected in series. This will result most "bending" transients as EQ points will interact and are interconnected. For shaping, band needs to be split into blocks, and this exactly what a multi-band compressor does.

This reduces the meaningful parameters to exactly one: dynamic range:

1. Define a dynamic range (in dB for an EQ point.
2. Figure out values for the parameters that keep it within that range.

So with the dynamic EQ below this would mean a manual tuning until you find some
values that seem to work, and depending on signal coming this could even mean automating those parameters, depending on how static the signal is. Also any change to the signal coming in would require re-adjusting them.

On the other hand, Pro-Q3 starts from the dynamic range as the input parameter, listens the signal and adjusts compressor parameters dynamically to stay within the range, without user intervention.

Not my cup of tea because the choice is between spending hours on it vs spending less than a minute figuring this all out 🀷

Job situation is looking pretty good! I have now some options that I can cope with. Most likely not going hack the planet under the bridge after September ;-)

My heartfelt condolences to the family and friends of actress Patti Yasutake. Fans will forever cherish her portrayal of Nurse Alyssa Ogawa on β€œStar Trek: The Next Generation.” Personally, I’ll remember her as a dear friend, whose sister was the late Irene Hirano Inouye, a founder of the Japanese American National Museum.

So earlier this year I wrote about this cybercrime rapper named Punchmade Dev, who wears outlandishly gaudy and expensive stuff around his neck and croons in videos in front of stacks of cash at ATMs, talking about how to do wire fraud, cashout PayPal and Cash App accounts, etc. The story showed how this Punchmade character seems to be a 22-year-old guy in Lexington, Ky named Devon Turner who operates multiple web stores that sell apparently compromised payment cards and identity information (alongside check printing software and tutorials on....wait for it...OPSEC!).

On a hunch that maybe Punchmade's lack of opsec might have caught up with him, I checked PACER and found instead that he recently sued his bank, alleging they discriminated against him for his race over his denied request to transfer $75,000 out of his account. Incredibly, Mr. Turner signed his pro se complaint filed in a Kentucky court with the same phone number and email address that are tied to the Punchmade domain names that are selling products like "ID+ High Balance CC, ID front/back, SSN, and 7$k-10k CC, for $80"

Here's the story:
In January, KrebsOnSecurity wrote about rapper Punchmade Dev, whose music videos sing the praises of a cybercrime lifestyle. That story showed how Punchmade's social media profiles promoted Punchmade-themed online stores selling bank account and payment card data. Now the Kentucky native is suing his financial institution after it blocked a $75,000 wire transfer and froze his account, citing an active law enforcement investigation.

Tim Walz is from Minnesota, which is the most Scandinavian state of US so he must be a great guy :-) AFAIK, he has Swedish ancestors. There's even a village called Finland in Minnesota, and active Finnish descendant community: https://friendsoffinland.org/

This can't be a bad sign ;-)

IMPORTANT NOTICE ⚠️

(Boosts appreciated)

The package for will be removed from the repositories in two weeks.

https://github.com/dillo-browser/dillo/issues/230

The current maintainer seems to be unable to continue taking care of it, and I'm not familiar with Debian packages to maintain it myself.

Is there a Debian maintainer who could help us by adopting it? We already have a working package:

https://salsa.debian.org/debian/dillo/-/merge_requests/1
