I chilled significantly on using Google for anything to do with business due to API (and offering) stability. (Still use Google for personal things.) But AI models seem orders of magnitude more fluid, so to my risk-averse eye, they're nothing I'd base my own business on.

I forget who said it, but Python isn't the best at anything but it's decent to good at nearly everything, and that's why it's become so popular.

I do a lot of what I need symbolically in SymPy for dynamics analysis. Past that, I can't speak for it. At University I used Mathematica, but I just don't need all it can do at this point, so once again Python has proven to be "good enough." Matlab will be a similar story (e.g., I've never seen a good alternative to Simulink in Python).

But for everything else outside very specific domain tasks? Mathematica and Matlab are terrible for a lot of reasons. So I'll go out of my way to stay within the Python ecosystem, though I'm not afraid to pull out the specialty tools when I just can't make Python do the task near as well and/or nearly as quickly.

Yes I believe software benefits uniquely, just like building tooling and automating software have long been easier in software than other domains. Humans defined all the rules of the world you live in, humans wrote strict rules in methodically parsable formats.

The moment you have to interact with the physical world or humans (psychological, imaginative, aesthetic, etc), there are often undiscovered or changing rules—or no rules at all. Or systems are subject to perturbations beyond a defined scope.

The other thing I believe is software developers are experts at doing the things that allow them to make doing those very things easier and more automated. And they do this in public, perfectly documented online.

Both because of the things I described above and because software developers have created the largest machine-accessible training set for plying their trade of any trade, ML—that is ultimately interpolating massive datasets to do things—is unsurprisingly uniquely successful for software tasks.

Well is it actually being used as a tool where the author has full knowledge and mental grasp of what is being checked in, or has the person invoked the AI and ceded thought and judgment to the AI? I.e., I think in many cases the AI really is the author, or at least co-author. I want to know that for attribution and understanding what went into the commit. (I agree with you if it's just a tool.)

On the other hand, if people who don't care enough to compile it for themselves try it out, the Python devs can be flooded with complaints and bug reports that effectively come down to it being in alpha.

You get both sides (yes, you might limit some who would otherwise try it out).

I think requiring people to compile to try out such a still-fraught, alpha-level feature isn't too onerous. (And that's only from official sources; third parties can offer compiled versions to their hearts' content!)

For me this is a set of general strategies for breaking down problems. Here are some I use. (Apologies if these aren't all orthogonal to one another; they just feel different when I'm thinking of how to break a problem down.)

1. Break down the steps. Can you find a recipe of steps for achieving the thing? Then start with the first step. Maybe that's a small enough task. Maybe you don't have to perform all steps in order, and you can find a small-enough step to do next.

2. Isolate the fundamental challenges. There is often a tough nut to crack within the problem. Can you isolate that from the rest of the project, and turn it into its own thing (I like to cast this as a "toy" problem)? When I say "isolate," I mean to remove all unnecessary complexity to getting at the fundamental issue. Suppose I want to figure out how to create a robust messaging network. There might be user interfaces and caching and different kinds of messages and different networks and different failure mechanisms and performance issues and ... So just create a "toy" at each step: First, simply send & receive a message. Don't worry about performance or worry much about robustness. You now have a small task but whose completion achieves a fundamentally necessary part of the larger task. Finishing that will feel good--you have something that works!--and you've made real progress. You might find examples of others doing something similar to this basic task as well, so you can work on your own but then compare notes to others to gain insights on why others have solved similar problems differently than how you solved it (you might have come to something better, or not; either way, you now have understanding of the fundamental problems involved). Now you can grow that toy or take what you learned from the toy and apply it to the larger task.

3. Similar to 2, but maybe a different POV: The physics joke is approximating a cow as a perfect sphere to study its dynamics. Simply the hell out of a problem! Maybe it feels ridiculously simple. Fine; now you are working with something completely tractable. You can then add in complexity to your model one wrinkle at a time.

4. Do something that's actually easy even if i might not be "significant" from the "big challenges to getting this project working" POV. Maybe you've been frustrated for a week or two trying to solve the tough-nut-to-crack bit of the problem. Even your toy problem remains (what feels hopelessly) broken! Switch over to creating the GUI or something superficial but that is easily tractable yet yields something satisfying to you when you finish. Simply stepping away from the hard problem for a day or two can re-motivate you when you come back to the hard problem. That time can also give your mind time to process solutions in the background (many people--myself included--have an "a ha!" moment when not thinking directly about a hard problem). And you are still being productive, moving towards the end goal. You had to make a GUI anyway at some point. Might as well be when you are stuck on the hard thing and feeling frustrated.

Getting good at breaking down problems took me many years. I credit my physics education as being particularly helpful (training thinking of problems & solutions in their extremes and always connecting solutions back to "does it make sense"). But much of the above is also learning my own psychology of how I work and what/when/how I am motivated to work and in the best position psychologically to solve a problem. I expect this isn't too different for many people, but the details can vary from person to person.

I welcome this question from interviewees and sometimes offer up the information without being asked.

I work in a small business where we do hardware, software, help the marketing folks, and do a little IT work where needed. I want someone who is curious, energetic, and enjoys taking on whatever challenge presents itself. They'll start in a pretty well-defined role in a well-defined domain, and I'll give them support in that role. But they will have every opportunity to branch out from there, and I believe the kind of employee I seek—as well as the company—will benefit if the employee fits this technical culture. I want to scare off people who want to be pigeon-holed and fed repetitive tasks.

To that end, I also like to discuss with candidates projects they've worked on in the past, rather than offer up new challenges I present to them. Our normal work week doesn't involve isolated puzzles or single activities that one finishes in an hour. Finishing a project takes a long time & requires acquiring new knowledge, skills, and understanding, so I want to explore in depth something the candidate had a long time to work on where this process did (or did not) transpire.

My POV is that I want to find a postdoc (or someone who could grow into this paradigm), not a clever parrot.

You act like you were misled, but the article, within the first few sentences, says he realized the tools are available to do this (including naming tesseract.js explicitly!), he just needed to glue them together. Then he details how he does that, and only then mentions he used an LLM to help him in that process. The author's article title is equally not misleading.

Was an earlier headline or subtitle here on HN what was misleading, but then that was changed to not be misleading?

64 bit unsigned integer nanoseconds gets you out to 584 years (that's the year 2554 if you're using the Unix epoch). That's good enough for me to use universally for passing times around in the internals of my code. User input and output are going to and from that representation.

Half as many, of course, if you use a signed integer. If you don't need nanoseconds, then use microseconds and you get 292 thousand years to work with.

Integers are just a bit easier than floats for timestamps in my experience (e.g., comparing floats to one another is fraught and you'll be fighting this at every turn in your code).

A couple big things: Fortran natively performs operations on arrays directly like Matlab or Numpy in Python (Matlab was originally a REPL-style front-end to Fortan), and Fortran compilers tend to yield quite fast code (though specific cases will have another language outperform Fortran).

You can read more about the language and its high-level features here: https://fortran-lang.org

That website/community was created in part by the original author of the Python Sympy library, Ondřej Čertík. He is also working on his own Fortran compiler that you can use via webassembly to play around with Fortran; find links if you want to play here: https://lfortran.org

I've only dabbled a little, but I like the general idea, and I appreciate a F/OSS Fortran compiler being developed like this alongside actively seeking to grow the Fortran community & push the language & its libraries forward.

I expect more widespread adoption of Fortran to be quite a ways out, but what Ondřej is doing for Fortran is necessary (not sufficient) for such adoption to be the case.

Did you evaluate Cython? I'm not anti-Julia, but I like that my Cython code is useable out of the box from Python, with no wrapping, and then users can continue to use their Jupiter + Python scripting workflows with performant bespoke modules complemented by the full Python ecosystem.

Someday I'll do a project in Julia. But for some such projects, Rust seems fully guaranteed to be performant while Julia might or might not be, so I might still lean towards Rust (unless one of the high quality packages of Julia removes a lot of development time, which is a decent possibility).
