  • 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.




  • Because an object is good at representing a noun, not a verb, and when expressing logical flows and concepts, despite what Java will tell you, not everything is in fact, a noun.

    I.e. in OOP languages that do not support functional programming as first class (like Java), you end up with a ton of overhead and unnecessary complications and objects named like generatorFactoryServiceCreatorFactory because the language forces you to creat a noun (object) to take an action rather than just create a verb (function) and pass that around.


  • Answer: there’d be far less software in the world, it would all be more archaic and less useful, and our phones and laptops would just sit at 2% utilization most of the time.

    There’s an opportunity cost to everything, including fussing over whether that value can be stored as an int instead of a double to save 8 bits of space. High level languages let developers express their feature and business logic faster, with fewer bugs, and much lower ongoing maintenance costs.



  • 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.




  • Yeah man, me too.

    I went to school for electrical engineering, my first job was at an architecture firm designing the electrical stuff for buildings (including making all the electrical drawings for bank branches so we had some professional crossover 😋), and I ended up teaching myself software to automate a bunch of our designs and processes. I was literally directly making building design and construction more efficient … Buuuut… The arch industry pays poorly and I realized they was no way of ever owning a house at the pace I was going so I left for software and doubled my salary in like 2 years. I went from senior electrical engineer to intermediate software engineer and saw a 50% increase… All in a country experiencing a massive potentially existential housing crisis, and the industry pay disparity directly incentivized me to stop working on it and go work doing mostly bullshit software work.

    The software industry is grossly overpaid for how hard we work and for how critical our relative contributions are to society, though even in the software industry the pay is incredibly distorted. Orders of magnitude more money goes to random social media bullshit and VC startups that go nowhere than to mission critical teams doing stuff like maintaining security and access control software.

    I’m so torn on this meme because on the one hand I have the same gut reaction of “yeah, but youll die if you don’t do jack shit in the woods, you kind of have to be useful to live”.

    But then I think about our society … the billions of dollars going to rich people who do nothing, the millions of people who work in jobs that are useless, or the millions who work jobs that actively harm society, and in that context, the amount and type of work does seem like bullshit. It’s not like going into your marketing firm 5/7 days of your life means a farmer gets to work less. People like to comfort themselves with vain thoughts like ‘we all just gotta do our partfor the system to work’, but that’s objectively not true. Lots of parts of our system are objectively bullshit and are excised completely through new laws and legislation and society keeps working fine, in some cases much better.

    A feature added late to iOS, and one they have hidden behind the pile of homescreens you have since every app you install is just dumped on them. On Android you swipe up from anywhere on the homescreen and you immediately search or browse.

    Lol no one is responding to posts about how much you like a feature with hate, unless you’re trolling the wrong community or youre the person in OPs post, saying that in response to someone making a criticism of a corporation’s monopolistic behaviour?

    It’s really not.

    Even just how Apple handles apps. If I asked you which company would present their apps in a neat organized alphabetized list that you can quickly scroll or search through, and which company would just dump them all in a mass of garbage on your homescreen and make you search for them, you’d assume it would be Google that forces you to search, but nope, that’s Apple’s terrible UX for managing the most basic aspect of a smartphone.

    Yes, but make a criticism of Apple’s monopolistic behaviour online and you’ll immediately have a million brain dead Apple fans screaming at you about how iPhones have to work exactly the way they do now or the world will fall apart.
