There are also LEDs with a built-in "candle flicker" effect. This teardown shows how it's done with two dies integrate into the LED package: the LED and an ASIC. They also demo a circuit using a small flicker LED and an amplifier to control a much larger LED.

I saw that happen once in a big presentation.

There was a team of students presenting their work to ~200 people. Right in the middle, a pop-up says updates are finished and the computer needs to restart. It has a helpful 60-second countdown, but "cancel" is grayed out, so all they can do is watch.

I was only in the audience and I still have nightmares.

I'm trying to find a sci-fi short story. Unfortunately, I do not remember anything about the author or title. It is at least a decade or two old, available for free online.

The entire story is set aboard a starship in deep space, and everyone has advanced technology (nanomachines?) that can repair tissue damage that would normally be deadly. Unfortunately, the ship is hit by a massive radiation burst, nearly killing everyone aboard, causing all kinds of damage, and contaminating much of what's left. Somehow, the worst affected have massive brain damage, and the nanomachines are driving them to instinctively seek raw materials for repairs--which can only be found in the brains of relatively intact survivors.

In short, the whole setup is basically an excuse to have space zombies. The nanomachines keep them alive even when their organs are falling out, but they're dumb and slow and they want braaaaains.

Other things I remember:

  • The protagonist is female, and was protected by the initial burst because she was working inside a large water tank.
  • The protagonist is trying to help her romantic partner, who is comatose, but it's implied they might wake up as a zombie.
  • The protagonist is trying to avoid killing the zombies when possible, because there is still a chance of curing them.
  • The protagonist is looking for raw materials that aren't radiation-contaminated, to help her partner and repair the ship.

This isn't funny, this is just the sad state of software these days.

It's not about money, it's about sending a message.

If you don't rock and stone, you ain't coming home.

Simple solution: Don't connect it to the Internet. Hackers hate this one weird trick.

My head canon is that Tony Stark has a superpower: everything he builds works the first time.

If it's really complicated, like an entirely new Iron Man suit, then it might malfunction once in an amusing way. Then he tightens a screw and it's perfect. It never fails outright or bricks itself.

In my experience, this is not how hardware or software development goes. I want this power so much.

Want to upgrade your F-91W? The open-source Sensor Watch is a board-swap that uses the same display, housing, and wrist-strap but lets you program your own functionality.

If you're writing Advent of Code solutions in Rust, then I've written a crate that can fetch the user input data directly from the main website.

Long story short, you provide it a login token copied from your browser cookies, and it can fetch the input data by year and day. Inputs are cached locally, so it'll only download it once for a given problem. This was heavily inspired by the PyPi advent-of-code-data package.

Unlike other AoC-centric Rust crates, that's all it does. The other crates I've seen all want the code structured in a specific way to add timing benchmarks, unit testing, and other features. I wanted something lightweight where you just call a function to get the input; no more and no less.

To use the crate:

  • Follow the AoCD instructions to set the AOC_SESSION environment variable.
    This key is used for authentication and should not be shared with anyone.
  • Add the aocfetch crate to your Cargo.toml [dependencies] section:
    aocfetch = { git = "https://github.com/ooterness/AdventOfCode.git" }
  • Import the crate and call aocfetch::get_data(year, day) to fetch your input data.

An example:

use aocfetch;

fn main() {
    let input = aocfetch::get_data(2023, 1).unwrap();
    println!("My input data: {}", input);
    println!("Part 1 solution: 42");    // TODO
    println!("Part 2 solution: 42");    // TODO
}

If this goes well I will submit it to crates.io, but I wanted to open this up for beta-testing first.

Is this one banana per employee? Or one banana and they have to fight over it?

This is an open-source FPGA project I've been working on for several years now. It's an Ethernet switch for FPGAs, but you can mix-and-match the usual RMII/RGMII/SGMII interfaces with unconventional options like a plain old UART.

My company uses it internally, but we decided to release it as open source. (Currently LGPLv3 but open to other weak-copyleft suggestions.)

Among other things, we've recently incorporated some new technology that allows picosecond-accurate timestamps to be compared across different digital clock domains. You can think of it as a group of NCOs that all track the same best-fit line.

Reddit users will prevail but also be injured so badly they need life support for 10,000 years. (It's a metaphor.)
