rootbear··on The Rise and Fall of World’s Fairs
My sister lived in the Knoxville area and my whole family went to that Fair, the only World's Fair I've attended. We had a good time, but for Knoxville, it was a financial boondoggle. I've still never been up in the Sun Sphere, which has struggled over the years. And yes, I remember the jingle as well!
rootbear··on Companies are buying washing machines to take the chips out and repurpose them
It's a great channel. I was also fascinated by his rice cooker episode. I had no idea they were so clever, combining thermodynamics and the physics of magnetism.

rootbear··on Consumer prices rose 8.5% in March – highest since 1981
I saw paper menus disappearing before inflation started going up. I took it as a Covid measure - no physical menus that needed to be disinfected after each customer used them.
rootbear··on How to make an IBM 1311 disk drive move around the floor
A person of my acquaintance owned a PDP-10 which he had in his apartment. Originally he had no memory for it and could only run programs from the registers and I remember thinking how strange that was.
rootbear··on The Beautiful Mind-Bending of Stanislaw Lem (2019)
I'm also a big fan of the Cyberiad, and Douglas Adams. When a bunch of us first heard The Hitchhiker's Guide to the Galaxy radio plays, we were sure Adams must have read the Cyberiad, as some of it seemed so similar in tone if not details. But I read somewhere that he had not read it when he wrote Hitchhikers.
rootbear··on Map of Surnames in Europe
I gave up as soon as I realized that the form at the top was an ad and not part of the page. What a mess!

rootbear··on A baby saved ‘Toy Story 2’ from near complete deletion (2021)
Ah, okay. I probably never knew about it, that was after I left Pixar. (This is Jim W. from Studio Tools, by the way. Great to see you here on HN.)
rootbear··on A baby saved ‘Toy Story 2’ from near complete deletion (2021)
It was.I don't know exactly what, but we had a lot of Octanes.
rootbear··on A baby saved ‘Toy Story 2’ from near complete deletion (2021)
That is not true. I was there. The film that was nearly lost was being made at Pixar. There was never any version of TS2 made by anyone else. I think this idea may come from the fact that Disney owned the Toy Story characters and if Pixar had later gone with another partner studio, it would be Disney making Toy Story movies, not Pixar. This was a major motivator for Pixar to stay with Disney.
rootbear··on A baby saved ‘Toy Story 2’ from near complete deletion (2021)
There never was a "Disney Version" of TS2. The film that was almost lost was to be the theatrical version and it was done entirely at Pixar.
rootbear··on A baby saved ‘Toy Story 2’ from near complete deletion (2021)
The linked article is much better. This event happened right about the time I left Pixar and I heard about it long ago. In the end, much of what was recovered from Galyn's workstation wasn't used. Some time after this event, it was decided that the film was not working and a huge rewrite was done. John Lasseter stepped in as director and, through Herculean efforts, the film was completed on time.
rootbear··on CentOS Linux 8 Reaches End-of-Life
My group at NASA/Goddard, which was almost all CentOS 7, is moving to a mix of RHEL and Ubuntu (with paid support). This has, of course, increased our costs, but the agency was under some pressure to only run OSs that had formal corporate support.
rootbear··on The Star – Arthur C. Clarke (1967) [pdf]
And Clarke had a tendency to be free with his usage of the word Universe, sometimes using it to refer just to the Solar systems. It throws me off sometimes when reading his short stories.
rootbear··on 25-Dec. Shout-out to everyone else at work
Quite a few of my NASA colleagues worked today to launch the James Webb Space Telescope, and I'm sure most of them didn't mind working on Christmas.

And I certainly appreciate all of those who work on the holidays to keep us safe.

rootbear··on What happens to developers who never go into management?
Pilots retire at the mandatory retirement age of 65, which a friend of mine will do next year. He'd rather keep flying and I imagine his employer would prefer that too, given the pilot shortage. But he will also admit that the job his harder on him now than it was when he was 25, so the rule arguably makes sense.
rootbear··on Space colonies of the future as imagined by NASA in the 1970s
Agreed on both points. I remember seeing some of these images back in the 70s when space colonies were first seriously proposed. The idea that I might live to see such things built was thrilling. But looking at these images now, they seem very naive. I suspect the reality of space colonies, should we ever build them, will be much less like an idyllic space suburb and more like a dense urban complex.
rootbear··on Ask HN: How many personal shell scripts do you use?
Mostly efficiency. A typical shell function doesn't spawn a new shell, which running a script would. On a modern system, it's probably irrelevant.
rootbear··on Ask HN: How many personal shell scripts do you use?
I seem to have about three dozen. Many of them are very simple and quite old and should probably be turned into shell functions in my .bashrc. Only a few are of any complexity.
rootbear··on .plan
I still have a .plan file, for nostalgia's sake:

  $ cat .plan
  To be the only person on this system who uses this obsolete feature of finger.
rootbear··on I'm “still afraid to use spaces in file names” years old
And a : in a file name at the GUI level gets turned into a dash! I just tried to name a text file "Foo/Bar 10:01.rtf" and it changed it to "Foo/Bar 10-01.rtf"!
rootbear··on Unfolding the Earth: Myriahedral Projections (2008)
In Larry Niven’s Ringworld, there were maps of various planets in the ocean, including one of Earth. I always wondered what projection they were in.
rootbear··on Classified tank specs leaked on War Thunder game forums again
I have only been in that position once or twice, but yeah, knowing some secrets can be exciting.
rootbear··on Experts Have Resigned from an FDA Committee over Alzheimer's Drug Approval
My sister, who is on Medicare, is paying over USD 10,000 a year for her cancer drugs (ALK-positive lung cancer). That's out of her pocket.
rootbear··on Experts Have Resigned from an FDA Committee over Alzheimer's Drug Approval
Neither my grandmother, who died of a stroke that was probably related to her late stage Alzheimer's, nor my father, who died of severe Alzheimer's, experienced terminal lucidity. But it seems to be a real phenomenon, and worthy of study.
rootbear··on Turing Oversold?
When I visited Bletchley Park a few years ago, I got into a conversation with one of the docents about the film and it was clear that they had a very low opinion of it there. Turing deserved a better film.
rootbear··on Scientists create matter from pure light, proving the Breit-Wheeler effect
Thank you! I was curious about exactly this. But now I have a new question. If a photon is sufficiently energetic to be capable of briefly fluctuating into an electron-positron pair, does that imply that it would, over a long distance, be slower than c, since the e-p pair can't travel at c for the brief moment it exists?
rootbear··on First Edition Unix Manual 'Miscellaneous' Section (1971) [pdf]
I knew glob was short for global, but I've never been clear on how the word global applies here. Perhaps it was something like "apply this command globally to all matching files"?

As for the terse abbreviations common Unix commands, recall that much of the early work on Unix was done on very slow teletype devices such as the ASR 33. At 110 baud, brevity is a virtue.

rootbear··on Ampro “Little Board” PC
My first personal computer was based on the Little Board. I put together a two floppy system and ran CP/M on it. I connected it to my HP19 terminal, which I had previously used with a modem to access the University computers. The system is long gone, alas.
rootbear··on The universe has already made almost all the stars it will ever make
I reread this most years over the Holidays.
