Yay! That's amazing, 65,000 major components, nearly 50 years, 40KB of memory, and it still runs.
Perhaps Bill Gates should have said that 40KB ought to be enough for anybody ...

Hah! And that was a hardware fault - drawing too much power shut it down!

I just don't understand how you can do remote engineering on a unit that is offline.
It appears to me that it must have fixed itself (which is no less impressing!)
Or, was it not completely offline - could it receive software updates from earth, but not respond to them until now?
Whatever the explanation: It is impressing.

Yeah they don't really tell you how it came back online, I'm assuming, like you that it fixed itself?
But you're right it is impressive.

How do you know member123whatever fixed himself? Maybe he did it with the support of family and friends.
Maybe he’s still broken

somewhat like the early USB ports that came out on some MOBO's, plug in too much and things stopped working. (say USB powered speakers, business card scanners)
the units would still accept commands ("scan!" "OK"... whir-ur-ur.u...)
the mobo still works, hopefully the scanning app doesn't lock it up, or if it does kill the OS hopefully they set the "Auto Reboot" option.
some of voyagers bits that collect data (photo's, RF waves, catch particles) do the work on their own, analyse then periodically feed back the results.
some updates were sent so some would run a bit slower/less often (they were already programmed to restart one by one because they knew further away power would be limited - probably added longer delays for that too.) and of course each sends back "X started OK" messages so if it fails during restart they will know where (apparently a while back a couple of things have failed and were taken out of the startup list).
So the unit wasn't fully offline (or would restart if it was) but from what I read (a while ago)
- designed to restart if it detected failure,
- upon restart first check (in some cases actually wait) for new commands before anything else
- the radio that receives commands is itself autonomous and has a buffer in case the core is down
of course takes a long time to see if it worked: Amazon "you're parcel has been sent" - takes a day or two before it arrives before you can confirm as complete, working, arrived at all.Quote: NASA engineers are troubleshooting the problem, but it's slow going given Voyager 2's distance from Earth. With the probe 11.5 billion miles (18.5 billion kilometers) away, signals take 17 hours to travel one way and mission personnel must wait a total of 34 hours to see whether a command worked.
after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

Following along on that theme, you can be pretty sure - no, make that pretty damn sure- that it's not full of parts labeled "made in China".

I just saw a notice regarding a recall on a certain very modern vehicle to update faulty software that was introduced in the first recall. We can initiate a software fix on a spacecraft on the edge of the solar system, but getting an update for the truck requires a trip to the garage. OTOH, I'm not sure I'd like my vehicle to receive an update/fix without my consent...still, I could see it being initiated from an email/website/app at least.

I finished the other book [^] and it really was fantastic, but since it is only about 230 pages it did go fast and didn't cover quite as much as I wanted.
Also, I already started forgetting the things I read. I will go back and take notes, but I also wanted to read another but slightly more in depth. Not so easy to find.
I've been looking around and I thought I was going to read either:
1) Algorithms in a Nutshell: A Practical Guide 2nd 2016 (O'Reilly): Heineman, Pollice, Stanley Selkow[^]
However, I read the free introductory sample and they just jump right in and are not real clear.
Then I thought I'd read:
2) Algorithms 2011 (4th Edition): Sedgewick, Wayne[^]
I've been seeing that Sedgewick book for at least 20 years. I remember the old C++ edition and I've never been able to get far into it. I decided to try again and I read the long sample.
This book was so focused on every little detail of Java that it just burned me out on it.
I want someone to begin at the beginning of Algorithmic Thinking and go on from there. That's what the first (Pragmatic) book did.
This One
Well, I found another. It's longer than the Pragmatic one (goes into more depth, covers more topics) and is by a great author Rod Stephens:
Essential Algorithms: A Practical Approach to Computer Algorithms Using Python and C#: Rod Stephens: 2nd ed. May 2019[^]
This has been very recently updated and uses C# and Python for examples (versus the Ruby  ) from the Pragmatic one.
So far I'm enjoying this one as much as the Pragmatic one and looks to be even better.
This is definitely step two on the way to algorithm learning.
Have you read it?

No but i really should. A lot of what I learned was a trial by fire while making parsers and lexers (one of the reasons i like them is they use things like finite automata and push down automata and a lot of different styles of data structures)
The rest i've either picked up as i went or on the internet via various websites like geeks4geeks or the occasional video.
I have no idea who this man is, but he makes everything from complex data structure tutorials to advanced stuff like parsing and stuff beyond mere mortals like compiling tutorials.
LL(k) parsing - tutorialspoint[^]
He produces for TutorialsPoint and if you find him in your google search and you're okay with heavy indian accented english he's a great resource, IMO.

Interesting...and that is some very deep technical stuff.

Yeah, but he's actually helped me over a couple parsing hurdles. The man seems to know everything.
I'd be a bit intimidated working with him, I think - not that I'd hold it against him.

new record for highest temperature: 18.3C / 64.94F [^]
PETA, in collaboration with Greta Thunberg's YSMC "You Stole My Childhood" group, has started a fundraiser for a rescue mission for penguins with heat prostration: geodesic shelters will be erected all along the coastal areas where penguins congregate; they will have special solar-powered high-frequency sound emitters tuned to the pitch known to repel walruses and seals, but, for male penguins, said pitch has been shown to function as an aphrodisiac.
