Don't want to spoil the joke thread with a serious response, but -- what processor DOES the JWST use? How out of date is it given the project started in the 90s?
The primary compute bits include the science instrument data handling electronics, the Solid State Recorder (SSR) and the Command & Data Handling processor (C&DH).
NASA has plenty of publications about the design, I haven't found anything yet that covers the SSR or C&DH yet, but this is an interesting article about implementing SpaceWire reliable messaging in an FPGA.

The science data handling here is done in an Actel AX1000 FPGA.

@cwebber @spritelyproject Yeah, one problem is that it's a bundle of indirectly related things.
Every time you criticize some aspect of "Web3", someone will say, "but WhateverCoin doesn't do that!", and now either you have to learn what WhateverCoin is, in which case they've made you learn about the thing they've invested in (and risk falling for their MLM scheme), or you ignore them and people accuse you of being closed-minded.
It's a bit like Umberto Eco's Ur-Fascism: https://theanarchistlibrary.org/library/umberto-eco-ur-fascism
I've been passively interested in sodium-based batteries for a little while (I think since someone on fedi posted about them). This is sounds like a cool advance on the tech:

if you write a GUI and design it so it blocks waiting on network access, and i find out about it, I'll punch you hard in the arm. I'm not even kidding

i think we should add htis to everything this surely has no glaring issues
Oh wow. I didn't realise there has been yet another log4j update because of anew vulnerability. We're now up to 2.17.
This new one is harder to exploit, and is not an RCE so it's not as bad, but still. This is just more proof that log4j s an overengineered mess. I've been of this opinion for years.
I'm not going to claim credit for predicting this, because I never actually saw it as a huge security vulnerability. I just considered it something that people spend far too much effort on. When you're invested in a piece of software, you keep tinkering with it and add new features when none are needed. Logging should be a solved problem, and Java already comes with a logging API. log4j has no real reason to exist other than momentum.
I had previously thought about the term "unleaded gasoline" and the implication that we used to put lead in gas. I even knew why. what I didn't realize though it's how that meant we were just pumping lead particles into the atmosphere for years
