Looking at delays among different CPU and chip companies (not just Intel), maybe there's a CPU bubble coming too in the timeline (long projection)?

E.g. Spectre and its ancestors are so fundamentals flaws in the core design decisions of a CPU that I don't think they will be ever fully fixed in ARM and x86.

zkVM is a cool project: https://dev.risczero.com/api/zkvm/

Requires quite selective use tho because it does not scale that well.

We're aware of reports that access to Signal has been blocked in some countries. As a reminder, Signal's built-in censorship circumvention feature might be able to help if your connection is affected:

Containers cross-talk in standards and even share sub-projects. CI's don't.

I think we as an industry could take the quantum leap and define standard for something like ".runner-ci.yml", and when split to multiple files ".runner-ci.d/*.yml". Then, just define stages and tasks.

That would also fix migration between hosts for Git repositories. Also, in a private company internal CI and external CI can sometimes be different. Only way to address is to support both, which is redundant work.

Feel bad for #news about #Intel. I was employed by Intel almost 11 years.

I hope they get their shit 2gether. #ffs

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 ๐Ÿคท

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 โ€œStar Trek: The Next Generation.โ€ Personally, Iโ€™ll remember her as a dear friend, whose sister was the late Irene Hirano Inouye, a founder of the Japanese American National Museum.
