ahem... https://github.com/ilayn/semicolon-lapack It is mostly out of habit. These days there are no differences between languages. Very often they compile to the same machine code. Fortran array syntax is light years

Ah, my bad. what I failed to emphasize is that many of the downstream issues are coming from the upstream restrictions so this is one of the major blocks that was causing some mayhem down the line. So indirectly we might have caused some he

Scipy maintainer here, the main issue with the wheels was the Fortran77 that was SciPy throwing wrenches into the mix. With C/C++ self compilation should be quite straightforward. We (all Scientific Python packages) really worked hard

It does not have to be in Fortran. It's just historical reason. If you want a C version of LAPACK I have one for you https://github.com/ilayn/semicolon-lapack

> Actually the column-major order of Fortran is more efficient for some linear algebra operations than the order of C, which has been inherited by many modern languages that do not care about high performance in scientific computations.

Read the sources carefully. Fortran quote is not his; he quoted it. Also remember that he was talking about pre-Fortran77 era. F77 tried to fix some of the criticisms though did not succeed fully. Here is a nice dig-in about the quote http

Similar to your mqtt converter you can make them ingest via Kafka or some other adapter in between. EMQX broker can directly write into TSDB but did not research into others whether they can or not.

Not the OTEL "telemetry" but sensors sending measurements from the field "telemetry". IT tech is, as usual, stealing perfectly defined engineering words and making them something else. TimescaleDB is perfect if you also

I'm working in the IIoT domain too. Your workflow is interesting towards the end. Any particular reason, why you don't write it to some db like Timescale or Influx at the end without any prometheus conversion?

NumPy has no Fortran code, for quite a long time now. SciPy has and it is being rewritten. What you mention is the ufunc machinery underneath which is all C. NumPy also has SIMD support (albeit limited to certain functions). BLAS is also C&

Same experience for me. I was able to buy my first drumset from the money I got for making a PHP+MySQL+HTML website for someone (also done all in notepad). I did not know anything about computers but I needed to buy a drumset. And that page

You should read more carefully to start with before accusing everything you see that does not fit into your narrative. requiring n time the word Greek until you are satisfied is a you problem. I don't care enough about you to attack yo

Anatolia is a Greek word. Read some. It will give you confidence about yourself so you don't seek confirmation from every piece.

This is a bit of a strange presentation of stability but I liked it. I don't agree with the phase margin absence in the other comment but it would have been much clearer if the author chose to present it once via a Nyquist plot, then s

I think you are also giving yourself too much credit on the separability of tense and mood and if it does not fit into your mental model you are discarding all other options. You can do the same research yourself. Mood and tense are not alw

You are thinking in western grouping of tenses on a verb conjugation of a different language. It is not the mood that is not inferred here. It is the property of the verb. Verb itself can be used to communicate the same information with a s

Yet another title to drive embedded device designers and control engineers up the wall. Why don't you make up your own bullshit words instead of randomly picking stuff from other places? That's not even multiplexing.

You misspelled oligopoly. My guess from your comment is that you don't have a handle on how academia works, which is perfectly fine. You don't have to. But then don't hold such strong opinions because what you wrote is not ev

Why should complex numbers need justification to be native type? If you need to do serious computation, you need them. If you say Zig is not for number crunching which, say, Java explicitly decided then fine otherwise searching for a reason

True, but column-major by default and 1-indexed unfortunately. Still quite nice that they are addressing these challenges head-on early stage unlike other new langs. I guess they had their share the pain like the rest of us.

You are essentially necromancing the ISO C99 discussion that happened already. Here is an answer that, after 25 years, is still wrong https://learn.microsoft.com/en-us/cpp/c-runtime-library/comp...

I hope Zig adds complex numbers before it is too late. It's a pity that they did not steal array syntax and slices from Fortran/Numpy.
