    > convince management of the value

    This presupposes that such convincing is even possible. Many, many companies have leadership that are simply terrible at identifying value. If you've never been part of a majority of developers advocating for, if not outright begging for, some huge ROI initiative to get the green light, you are very fortunate.

    There are great counterexamples, like Valve, which is known for giving developers an extreme degree of autonomy, and they benefit greatly from that approach. For each Valve, though, there are dozens of companies that manage to succeed despite themselves.

    Take Microsoft, for example. One tiny, yet representative, example: the way the Windows Terminal team handled a suggestion from Casey Muratori to take their software from abysmally slow to lightning fast:

    https://github.com/microsoft/terminal/issues/10362

    A quote from one of the Terminal developers, dismissing the suggestion:

    > I believe what you’re doing is describing something that might be considered an entire doctoral research project in performant terminal emulation as “extremely simple” somewhat combatively…

    Just how difficult was such an endeavor in actuality? Well, given that Casey implemented his own terminal emulator from scratch and incorporated the functionality he was proposing in a mere weekend... not a whole lot. Relatively minor effort for a huge return on investment. It took Casey explaining the concepts, then providing a working proof of concept, and finally a bunch of backlash online towards the Terminal team to get them to do the right thing for themselves and their users.

    Yes, we are working on it! :) Taking some of the learnings from current experimental JSON Object datatype, we are now working on what will become the production-ready implementation. Details here: https://github.com/ClickHouse/ClickHouse/issues/54864

    Variant datatype is already available as experimental in 24.1, Dynamic datatype is WIP (PR almost ready), and JSON datatype is next up. Check out the latest comment on that issue with how the Dynamic datatype will work: https://github.com/ClickHouse/ClickHouse/issues/54864#issuec...

  • ImHex

    🔍 A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.

    Project mention: Ask HN: What Underrated Open Source Project Deserves More Recognition? | news.ycombinator.com | 2024-03-07

    ImHex

    “A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.”

    I actually used it not too long ago to inspect why a mp4 file wasn’t valid. The pattern language that they have is quite nice and having sections of the hex highlighted and being able to see what structures they represent and what data was on those structures was very useful!

  • C-Plus-Plus

    Collection of various algorithms in mathematics, machine learning, computer science and physics implemented in C++ for educational purposes.

  • emscripten

    Emscripten: An LLVM-to-WebAssembly Compiler

    Project mention: Python HTTP library 'urllib3' now works in the browser | news.ycombinator.com | 2024-01-30

    Browsers limit the ability for these platforms to use raw sockets, there simply is no API for it. The best that can be done /today/ is to use WebSockets, which are not the same thing any can't be used for HTTP requests without the server expecting a WebSocket connection:

  • solidity

    Solidity, the Smart Contract Programming Language

    Project mention: Smart Contract Programming Languages: sCrypt vs. Solidity | dev.to | 2024-04-05

    Solidity Solidity emerged as the first-ever programming language for smart contracts and remains the most extensively utilized language in the Web3 space due to its first-mover advantage. It serves as the primary language for developing applications today on Ethereum and Ethereum Virtual Machine (EVM) compatible blockchains, including Binance Smart Chain and Tron.

  • Marlin

    Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

    Project mention: Why Prusa is floundering, and how you can avoid their fate | news.ycombinator.com | 2023-12-26

    There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

    Klipper by contrast is a breeze to read through[2].

    I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

  • rpcs3

    PS3 emulator/debugger

    Project mention: Idk if anyone's done a one-handed hitless run of the game or anything crazy like that, and this is 100% not that (i get hit A LOT on these runs) but Im still pretty proud of this. | /r/shittydarksouls | 2023-12-10

    The emulator: https://rpcs3.net/ The rom: https://vimm.net/vault/24833 I forget if you need anything else but finding a video on YouTube is not very hard for rpcs3, a bit complicated, sorry I can't remember how to do it all, it's been a while.

  • WLED

  • polybar

    A fast and easy-to-use status bar

    Project mention: Is there a way I can tell which exit node I am using from CLI in Linux? | /r/Tailscale | 2023-12-08

    I'd like to just be able to write a short shell script to check if an exit node is in use, and then pipe that output into polybar which I use anyway. The problem is that I can't find an option in the tailscale Linux CLI client that will show me whether I'm using an exit node or not. Is there a way to do this?

  • wslg

    Enabling the Windows Subsystem for Linux to include support for Wayland and X server related scenarios

    Project mention: FreeRDP: A Remote Desktop Protocol Implementation | news.ycombinator.com | 2023-09-28

    WSLg(Windows Subsystem for Linux GUI) uses RDP and FreeRDP to work: https://github.com/microsoft/wslg

    I haven't tried it yet, but I'm hopeful the experience is better than last time I tried Hyper-V enhanced linux experience. I imagine this use case is getting FreeRDP way more attention.

    For years I've developed in a Linux VM on a Windows host via VirtualBox. The typing lag on this, particularly in IDEs like VSCode and Rider, finally got to me. So, I moved over to WSL and have to say; the experience is amazing.

  • Cataclysm-DDA

    Cataclysm - Dark Days Ahead. A turn-based survival game set in a post-apocalyptic world.

    Project mention: Weapons for 'Giants' | /r/cataclysmdda | 2023-12-11

    And that sucks! I really wish being Huge (or Tiny, but I haven't tried that personally) felt more distinct than it does. You really shouldn't be able to operate holdout pistols, but you should be able to stuff a thanksgiving turkey in your coat pocket.
