Why not use Claude one single time to create a service that does this? I have this same question with 90% of the 'simple' use cases I see for these task runners, it always seems more efficient (not to mention consistent) to have it generate the service.

No the shortage goes back to Regan when their justified strike was busted. It ended the PATCO “union” and was a negative turning point for labour unions in general.

They didn't tweak their prompt styling request enough... The ChatGPT world is depressing.

>> Even if it only catches one small, it could save thousand of dollars down the line.

Or it could send a design team down thousands of dollars in false positives/false negatives. With zero benchmarks provided, it is very fair to question a product that could have material negative impacts on a hardware team.

This is really great, both from a specific application perspective, but also the approach. Really enjoyed looking through the repo and was inspired by your work.

C#/dotNet has Ahead of Time compilation that works very well with containerization. Obviously there are still overheads for the AoT runtime, but it is pruned.

I had an Abloy Protec2 malfunction while locked (PSA don't use them for key-only sashlocks) and the locksmith drilled it out in ~10 seconds. That is the last time I spend that kind of money on a lock!

My assumption is that there could be higher dimensional 'token' representations that can be used instead of vision tokens (though obviously not human interpretable). I wonder if there is an optimisation for compression that takes the vector space at a specific level in the network to provide the most context for minimal memory space.

Well said, I would buy them in a heartbeat if it was from a moral company.

This was build originally with WPF and C#, but with an in-house MVVM framework. I have been slowly moving it to Avalonia, which I highly recommend.

This is my own software, but – as a project engineering data exploration tool – high information and functional density was a key goal:

This is really interesting, I'd love to see this perspective incorporated into mapping software like google maps/streetview.

They mean distorted, not squished for both.

New comment by achr2 in "A love letter to the CSV format"

achr2 — Thu, 27 Mar 2025 12:08:40 +0000

It’s all a pros and cons.. the benefit of those characters are they are not used anywhere else, hence you never have to worry about escaping/quoting strings. But obviously most of my csv usage is automated in/out.

achr2 — Thu, 27 Mar 2025 01:40:59 +0000

Using ascii 'US' Unit Separator and 'RS' Record Separator characters would be a far better implementation of a CSV file.

I bought one of these Marshall speakers to use as a practice amp, only to find that the dsp latency is unusably bad. Maybe this is an option…

The only real landmine for c# is the default thread synchronization. If it was inverted, the language would be much better off. I think they also made a mistake in removing the OOTB method for throwing away the sync context, but I guess there are many third party libs that provide it.

A second recommendation for Avalonia. It deserves the acclaim.

Later SNES games also used a timing check for region locking to identify PAL vs NTSC clock frequencies. The mod I did, nearly three decades ago, was to add a toggle switch with a second crystal that would change the clock frequency and allow the PAL game to be played on an NTSC system. Wait a few seconds while the game booted up and then switch back and enjoy the unreleased in North America "Terranigma".

New comment by achr2 in "SQL is syntactic sugar for relational algebra"

achr2 — Sat, 23 Mar 2024 15:47:13 +0000

You should look at LINQ in C#/.net . The SQL-like syntax always has a function-first equivalent, that gets across this point fairly eloquently.
