Are software and systems engineering students still being taught Therac-25, I wonder?

re: expanse S06 but not really spoilers 

@izaya nope. I'm giving the book version the benefit of the doubt until I read the books 😆

expanse S06 but not really spoilers 

@izaya watching ep 4. I was right. TV Holden is that stupid.

I like this pair of videos. I remember someone was lamenting the prevalence of the claim that nothing is ever really true. They claimed that people who said such things were ignorant of mathematics. At the time, I had no response, but my understanding of mathematics has always been that it's a family of tools for reasoning towards things that are necessarily true *given certain premises*, and without that last bit, claims about truth are, at best, incomplete. Grant states essentially that succinctly in the second video, which is nice to hear from someone who is way more mathematically adept than me.

@PsychoCod3r on GitHub, yes, but also at work. at work it serves some of the same functions, although, since I'm doing less design and architecture at work, it's mostly writing up big reports. at work, the bigger advantage of our issue tracker is team coordination: I work with a relatively large team of folks in different subdisciplines (systems engineering, security, computer infrastructure) and we would be constantly creating ad-hoc systems of reference to identify work that needed to be done if we didn't use the tracker as a medium of communication.

@mzan maybe. in the past I read some summaries of GTD and I've figured out most of the tactical stuff just through working on actual problems with deadlines. the long term strategic stuff, where you're talking about life goals... yeah still working on that. tbh, I'm skeptical of pop psych claims that reading some book will get me to sort out my whole life though

At #softwareheritage we are running our 1st ever end-of-year fundraiser. Goal is 100 donations by Dec 31st.

*You* chipping in will help a lot (in fact, exactly 1% 😬) and contribute to preserving software source code for future generations!

Issue trackers are a godsend. If I couldn't write up the various ideas I have while working on other things, I'd never get anything done. Either I'd be flitting around to lower-prio tasks or I'd be constantly tripping over issues that I happened upon earlier or I'd straight up forget to do things.

TODO lists help, but I've never managed to consistently review and clear my TODO lists. That's more often where tasks go to die.

I would be a lot more impressed with the Wolfram physics project if they could provide answers to questions like this without a lot of jargony crap. IIUC, he's saying their physics theory (?) is compatible an accelerating expansion which is currently called an effect of dark energy.

Covid19 vaccine availability 

@JimG media in which country? it'll probably get picked up in a few days in the states. I'm thinking npr, cnn, fox. getting approval in India isn't the biggest deal here. even if the lack of parent means it gets more uptake, I've generally understood the problem to be of manufacture and distribution, which would still be problems with this vaccine. I could easily be wrong though as I haven't looked into the problem very deeply

Knowing launched 11 (plus?) years later than originally scheduled, I feel less bad about my projects that have taken years to reach a stable point. (Granted, I'm not fielding a multi-billion dollar space telescope, and I don't have an international team to manage, but that's not really the point)

true zen of programming is realizing your problem doesn’t need to be solved at all

aww. E O Wilson died. Told some interesting stories about ants in a podcast I listened to.🐜

rolls I baked. I had the dough in the fridge for maybe two days after about an hour proofing at room temp. about 2 parts "bread flour" to one part whole wheat flour. rolled out into a tube over a mixture of dried basil, cut into roughly equal portions and tried to roll into balls (they mostly kept the shapes they were cut into). dipped individually into a mixture of extra virgin olive oil and garlic salt. baked at 400°F (204.4°C) for about 30 minutes on non-stick parchment paper sprinkled with corn meal.

has a slight sour taste, which I like. slight crunch on the bottom.

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.
