Question:What do I need to be employable in IT or computer development? What kind of skills, documentation, etc? Preferably things a motivated techie can learn/produce in a matter of a few months.I'm just looking for a job that I can get, that'll keep me alive, and that I can give a damn about.

@robdaemon Yup. Like, writing an OS in Rust is about 90% dark Cargo magic and only about 10% Rust.

I wonder if there's a seamless way to use multiple UNIX accounts from a single X session.

I wonder how hard it'd be to make an analog TV decoder.(I'm guessing, not very.)

On the one hand, I know all the fancy dark mathematics necessary to describe the specific operations needed to decode the signal.On the other, I've always considered analog as somewhat a matter of dark engineering,so this'll be a good learning experience.

It'd be even easier to program one onto an ADC, but then I imagine that ones that can handle the necessary 1 GHz sample rate at a workable bit depth don't come cheap.

Ok, bad news: my existing oscilloscope is on the noisy side, and has a pretty suboptimal resolution.Good news: replacements on eBay are quite economical.Bad news: apparently shipping a particle accelerator across 🇺🇸 is kinda slow.Good news: I have a few different options to improvise one, if so required.

@Archivist Yeah.Unfortunately, good luck displaying waveforms on a magnetron.

Does anyone know if anything particularly interesting happens if you overclock a bunch of 65x chips (at minimum, 6502 and 6522) to 16 MHz?

Ok, so:the two most powerful x86 interpreters I have (assuming <=8 threads) are a top-of-the-line AMD chip,and Rosetta on an M2.The performance is comparable (with the M2 having the advantage of native ARM code for better performance).In terms of power:The M2 recently lasted a full 2 days on battery,and the AMD manages to gain a temeprature well into the 10's K above ambient at the BIOS.The continued existence of hardware x86 is an environmental issue.

Question:is MacOS decent for servers? Just asking because I have an old x86 one lying around.

@urusan No, it just means it wasn't specifically optimized for the controls. If the game works on Proton on any other AMD64 linux box, it'll work on Deck just fine.Steam has more specific information on their storefront about compatibility; and there are a lot of games that run fine on Proton, but that Valve doesn't consider supported.

One thing I've noticed about all the modern stack machines (WASM, JVM, LLVM etc) is that they are extremely complicated, in ways that physical architectures aren't, with things like virtual-hardware type checkingFor compiler intermediates at least, this makes sense.But for application formats, this can't be efficient.And with computers already "expiring" from obsolescence alone routinely, I'd say efficiency matters.

Plus, I'm not convinced there's anything inherently secure about it.If we just let applications use an MMU, it'd be a lot easier to sandbox untrusted code, and then it wouldn't matter what that code does.And modern systems already have multiple MMU layers (for things like hypervisors), so this isn't exactly an impossible task.

Question:are there any good open-source SystemVerilog simulation toolchains?Verilator only has the synthesizable subset, Icarus only really supports Verilog, and Modelsim is commercial

Horrible idea I've been thinking:SystemVerilog as a native software language.It supports all the dark magic OOP stuff you might want, it interoperates with C, it's inherently parallel, and if your code happens to contain synthesizable modules, you can plug in an FPGA to run them.

Question:I'm planning to hook a 65x-series processor up to (amongst other things) a USB-A port.This requires bit rates up to 12 Mbps. Even if I use a DDR shift register for the USB transceiver, that's 6 MHz.I'm not aware of any 555 variants that go that high. And I'm not aware of any other ways to make a PLL like what USB requires.

Question:how quickly will swap usage wear out an SSD? And is there a simple way to directly check SSD wear on MacOS before it becomes a problem?I'm asking since mine is basically RAM at this point, and I need it to last a good while since it's my only good computer and I can't afford to fix it if it breaks.
