  • For software to run on a computer, it needs to tell the computer what to do, “display this picture of a flower”, “move my character to the left”, “save this poem to a file”.

    And for a bunch of different software to all run on the same machine, they all need to use the same basic set of instructions, this is called the machine’s Instruction Set.

    Because the instruction set has to work for any software, these instructions don’t look that readable to us, instead of “show this flower” they might be “move this bit of memory into the processor”, but software builds up millions of those instructions to eventually display a flower.

    Intel processors used a set of instructions that were called x86, and then when AMD made a rival processor, they made theirs use the same instruction set so that their processors would be compatible with all the software written for Intel processors (and when they needed to move from 32bit instructions to 64bit instructions, they made a new set called x64).

    Meanwhile Apple computers for a long time used processors built by IBM that used IBMs PowerPC instruction set.

    Now many companies are using the ARM instruction set, but ARM is still a private company you have to pay licensing fees to, so RISC-V is rising as a new, truly open source and free to use instruction set.



  • For 3D Modelling / Printing, if you have even a little bit of programming / scripting ability, OpenSCAD is amazing.

    It’s basically just a small scripting language for generating 3D objects and performing 3D modelling operations and its so handy to be able to store important info as precise variables, and create new objects and cuts and stuff just with for loops and if statements.

    I use the web version a lot of the time, and while it could use a little work, it’s pretty amazing.



  • I’m not as hardcore as most, I run windows as my main OS, but I do love my LG Gram 17" laptop from ~3-4 years ago.

    It’s powerful enough for general use, webdev, and very light 3D modelling, and it is insanely light and portable. I have a 14" MacBook at work and the gram is lighter than it, thinner, not that much bigger, and far more durable.

    Great keyboard and trackpad, giant screen (I wish it was brighter but this is the version from 3-4 years ago), and surprisingly solid Bluetooth, microphone, thunderbolt etc.
