  • Radio telescopes. While I don’t know the complete process of how an image is created, it’s likely a composite of hundreds of thousands of points where radio wave strength was measured.

    A very basic explanation is that each radio antenna likely takes a reading of some kind for each equivalent pixel in the resulting image. Over time, you can build an image.

    Again, I don’t know the full details of how the full image is recreated. It seems super complex reassembling millions of data points from antennas that are located on a rotating earth that is also rotating around a sun. The position of the earth probably has a huge impact on radio signal strength at any given time.





  • It’s a markup language(ish) but it’s not a programming language. XML would be closer to programming, IMHO, since you could have simple things like recursion. That example is even pushing what I would consider “programming”, but anyone can feel free to disagree.

    SQL is in the same category for me. It’s a query language and can get super complex, perform some basic logic, but you can’t exactly write “snake” in it. Sure, you could use cmdshell or something else to do something more complex, but that would no longer be SQL.

    My simplistic expectation of an actual programming language would be that you can automate an entire platform at the OS level (or lower) instead of automating functions contained within a service or application. (JVMs and other languages that are “containerized” are weird outliers, by my definition.)

    I am not trying to step on anyone’s toes here. I just never have really thought about what I personally consider a programming language to be.





  • If you believe in technical analysis of stocks, NVDA formed a double top in mid-July which is an extremely bearish signal. (If I am not mistaken, it’s caused by many investors switching from long to short position… Or some kind of magic like that. The data is out there regarding short sales, but I just gotta look, and I am lazy.)

    But yeah, something more realistic is the recent trickle of news about OpenAI starting to falter financially which is compounded by the recent (free’ish) release of Llama 3.1.

    LinkedIn is silent on AI, and has been silent for a while. The AI snakeoil companies are dead silent on there now and most major companies have reverted their direct marketing back to pre-AI crap.

    So yeah, the cracks have been forming for a while and I think NVidia has better things to worry about than a dedicated AI chip. (“Design flaws”, my ass. )


  • Yeah. Modern phones are awesome if you need to use every feature to its fullest. I love that I have the opinions to access my accelerometer or GPS independently. Since I do a bit of CAD work, having a high quality camera is awesome for photogrammetry. But see, there is a caveat: It’s the right tool for me and worth my $1K to have an up-to-date device that has a reasonable bit of compute.

    Otherwise, nah. I just got a resin 3D printer that only has a USB connector. No cloud, no wifi, no bullshit. It does its one job well and that is all I care about.

    It sucks that most people are basically trained from birth that “more is better” or “brand new is better”. It took me years to de-program myself from that shit.



  • Folding phones are still a status symbol of some kind and the actual utility of a large phone screen is lost on most owners. Once most of the R&D cost is paid off and the tech starts to plateau, it might get cheaper?

    I see foldable screens as a work device. Sure, a portable movie theater would be a good perk, but it would absolutely rock as a commercial all-in-one console for a 3D printer farm or something. If there is enough commercial value in a device like that, $2k could be a bargain.
