  • AI is currently all the rage. I know a guy who does neural networks training, and it’s the closest job to Pokemon trainer that you can have. He does not know any programming language, it’s all purely data processing, and it requires a heavy math background. It’s still an 8 hours per day job in a corporate environment, and a half of it is fixing his computing farm, because there’s no dedicated sysadmin for replacing burned videocards.

    Another math-heavy option is signal processing. I’ve worked in a company which produces wireless communication hardware, it’s like 200 people, and there were two signal processing guys who patented an algorithm which increases data throughput by something like 0.5% in some specific high-noise scenarios, they are listed together with CEO on their website About page. That said, all the easier tasks for signal processing are already done, we’re already at the theoretical limit of Shannon theorem, so you’ll only be making gradual improvements.

    I would also recommend cryptography research, but it requires a lot of coding knowledge, even if you’re not writing any actual code, and paranoia is pretty much a requirement.








  • You can set up your own IPv6 server, and it will be accessible from every other IPv6 device. Do you want to create a Lemmy server using only your phone and Verizon mobile data? Yes you can! *

    * Instructions for installing Linux environment on Android phone and setting up free DNS and HTTPS certificates are not included.

    That’s the main point. IPv4 fails because half of all existing IPv4 devices cannot access the other half of IPv4 devices directly, they have to go around using some kind of relay server, which inevitably complicates communications and costs extra money.


  • It really depends. One specific shop near my home has good quality frozen meat pancakes and dumplings. Yeah I have made dumplings by hand some 20 years ago, but those frozen ones are simply better. Maybe I can do some exotic dumplings with a buckwheat flour and a lot of eggs, but that would not necessarily be better, just different.

    On the other hand, pasta sauce prepared from scratch will always taste better than store-bought one, mainly because the stores here only sell ketchup and mayo, and pretty much all pasta sauce here is some variety of tomato concentrate with a bit of carrots.


  • Most vector rendering libraries have options to disable all the fancy stuff like Javascript and external links. If you manage to find one that supports it in the first place. As for resource usage, the server sends image files without decoding, so whatever forkbomb you will manage to include into your SVG will only crash Lemmy clients, so, ‘not our problem’. Maybe it will become a problem for the server when generating thumbnail image.


  • If you want to understand how 3D projection works, it’s better to solve a few trigonometric equations by hand on a piece of paper, then copy these equations to your Python code.

    If you just want to quickly make your own 3D renderer, simply use OpenGL API and the corresponding projection matrix. It will run the same exact formulas inside the driver, just in a 4x4 matrix form, and you can simply experiment with modifying each element of your projection matrix to make your 3D scene rotate the way you want, without bothering to understand the math.

    Simply copying some formula from the net will most probably fail.






  • This needs some simple hardware trigger, that can be queried by bootloader, but specific wnough so it won’t trigger in your pocket. If buttons are unavailable, I can propose several idead:

    • Cover the proximity sensor 10 times per second. Requires good motor skills.
    • Shine separated red, green, and blue lasers into three of the phone cameras. You’ll need a box with three different-colored LEDs to cover cameras module.
    • There is a low-speed data channel in wireless chargers. Just add the button to the charger instead of the phone.
    • Put your phone at exactly 2.5G of acceleration. Accelerometer is easy to use even from the bootloader, however you will need to put your phone in a centrifuge and reboot it while it’s rotating.
    • An option ‘Reboot into recovery’ in system settings, duh. Won’t help if your ROM fails to boot.
