The guy behind that page and bitvise appears to have gone totally crazy during the pandemic. On his blog, he said in 2021 "I forecast that 2/3 of those who accept Covid vaccines are going to die by January 1, 2025."

And in 2022, he wrote "Covid-19 is mostly snake venom added to drinking water in selected locations. There may also be a virus, but the main vehicle of hospitalizations is boatloads of powder, mixed in during 'water treatment.' Remdesivir, the main treatment for Covid, is injected snake venom. mRNA vaccines hijack your body to make more snake venom."

This reminds me of a little bit of trivia. In very old versions of BASIC, "FORD=STOP" would be parsed as "FOR D = S TO P".

I found that amusing circa 1975.

I'm not sure what you're claiming here. Civilian employees are less than 3% of federal spending, so it won't have a measurable effect on spending. Some employees, like IRS employees, bring in revenue.

Re:The Disunity of Consciousness in Everyday Experience on Sunday September 15, 2024 @12:20PM (#41548389)
Emo Philips once said "I used to think that the human brain was the most fascinating part of the body. Then I realized, whoa, ‘look what’s telling me that’."

There seems to be this naïve view among some philosophers that what our verbal stream of consciousness reports is somehow the most important part of our "mind" or our "consciousness", some even saying that verbal thoughts are the only thing that are important enough to be called "thoughts"!

I say: look what’s telling you that! I mean that very seriously.

I've always assumed that the brain has to have many parallel things going on at the same time and we have some limited awareness of these things and some ability to coordinate and direct the different parts of the brain, but it seems to be rather limited. It can't be complete, just on a Turing/Goedel basis, but anything approaching completeness would mean slowing our thoughts down to the slowest parts.

I remember reading about the Libet experiment decades ago and how some people thought that it disproved "free will"— whatever that could possibly mean. The impulse to report a decision to move a finger came after the impulse to move the finger. So? They were apparently assuming that the mind was some synchronized, sequential process and that the verbal report of what "the mind" was intending to do was supposed to come at the same time or before the impulse to move the finger. What???

Even a view of a single stream of "attention" or "executive process" seems dubious. Yes, we have all had the experience where something that's mostly automatic/unconscious suddenly requires our attention. For example, you're driving a car and suddenly a novel situation comes up and you need to turn off the radio or tell the passenger to shut up so you devote all your attention to driving. But just normal driving requires an enormous amount of processing of different concepts and coordinating different parts of the brain.

There was an experiment (Maier's two-string puzzle, I just found by google), where a scientist tested people's ability to solve a problem figuring out how to tie two strings together that were hanging from the ceiling, too far apart for anyone to grab both at the same time. Some of the participants were given a non-verbal "hint" of how to solve the problem. But, when asked later how they solved it, most of those given the hint didn't mention it! Were they "consciously aware" of the hint at all? That was an actual experiment relevant to the idea of a unity of consciousness.

Anyway, mine is a very limited, amateur, mostly 20th century perspective on the ideas. I'd be interested in what others have to share, especially actual experiments and not so much philosophers examining their verbal thoughts.

Re:The curious case of the abominable shower on Thursday November 23, 2023 @04:39AM (#38391063)
Many decades ago I read a book which had an anecdote of some military officer taking an important message to the White House and he was told to take it right to President Johnson in his bathroom. The President came out of the shower to accept the message and the officer noticed the shower shooting water from several angles.

The President saw the officer staring at the fixtures and asked, "Son, do you have a shower like that?"

The officer replied, "No, sir!"

President Johnson said, "Then, boy, you got a dirty ass!"

Re:The Ten Rules of Schema Growth on Wednesday November 01, 2023 @12:09PM (#38100327)
> never allow more than one app to share the db

I'm a little stunned by this suggestion. I've worked in quite a few different context for application systems, e.g. retail, manufacturing of fiber optic cable, manufacturing of telecommunications equipment, laboratory information management, etc.

I wouldn't even know what you mean by "app" in this context. There may a dozen or more classes of users who collectively have hundreds, even thousands, of different types of interaction with the system.

Sometimes there were natural divisions where you could separate things into a separate database. For example, the keep/dispose system for laboratory specimens, which tracked which specimens needed to be kept for possible further testing, where, and for how long. But most problem domains were not like that.

And sometimes we had to interact with other systems because they were for a separate division (because of mergers and acquisitions). But those kinds of separations made for more limited functionality and more difficulty in managing change, not less.

It's in the title of the work, though, which may be different than appearing in the work, though. And it's in Japan, where the law may be different from US law.
It's not 1987 any more and Excel doesn't use the file format that it used back then. The price of main memory and long-term storage has declined by many orders of magnitude since 1987.
> The New York Times was happy to report her claims[2], and didn't even mention that their reporting of the meeting when it happened showed no evidence of this.

The article does mention the earlier story and links to it in the paragraph:

> The existence of the meeting has been public since shortly after it happened in December 2018. The New York Times reported shortly after the meeting took place that Ms. Warren had sought it “as a courtesy,” and that neither party had tried to gain the other’s support or discourage the other from running. But the two senators were the only people in the room, and all reports of what was said had been secondhand.

The 3rd part is a lot of fun. Billy Preston shows up and they start having a really good time in the studio. Then they decide to give a concert on the roof and the staff work to stall the police.

Re:Lawrence Wright on Larry McMurtry on Thursday September 14, 2023 @07:46PM (#37516325)
You might be interested in Wright's lecture/one-man-show My Trip to Al-Qaeda, where he talks about his research for the book The Looming Tower, going overseas to meet Al Qaeda members and their relatives.

It's available for free several places online, e.g. https://tubitv.com/movies/312561/my-trip-to-al-qaeda

The second part of the book, which was about the FBI's pursuit of Al Qaeda, was turned into a dramatized series on Hulu. It's very much from the FBI's point of view. One of the main "characters" in the series is Ali Soufan, played by an actor. The real Ali Soufan was one of the producers.

And Johnson continued those policies.

That's not what this case is about. The California Department of Education is not claiming that Thomas Dee misused confidential data. The CDE said that their contract with Dee means that he cannot testify against them or participate in an unrelated case against them.

Re:Fun with Char in SQL on Thursday June 29, 2023 @10:16AM (#36520657)
This is a holdover from COBOL, which uses fixed-length, space-padded strings.

I read an interesting bit in a DBMS paper once about space-compression and the oddities of space-padding collation order.

As this article says, 'A\x03' is supposed to come before 'A' in collation order, because the 'A' is (conceptually, at least) padded with spaces before being compared.

So in the paper I was reading, they had to have different representations to compress runs of spaces, one for when the spaces are followed by a character > space (or end-of-string), and another for when the spaces are followed by a character < space. In the final representation, you can just use memcmp to compare the strings.

I think that same paper talked about the pains that IBM had when they first ported DB2 (or maybe another earlier DBMS) to a little-endian architecture. There were many places in their collation and indexing code where they compared 4-character segments using integer comparison. That works great on IBM's big-endian architecture, but not on, e.g. x86.

Here's what Ted Kaczynski wrote in February 2018 about the experiments in a letter[1] to journalist Andrew Kaczynski (no relation):

> ... media reports about me have generally been loaded with bull manure. In particular, reports about the Murray study have been wildly, wildly exaggerated. People write to tell me how sorry for me they feel because I was "tortured" again and again by the Murray group as part of an "MK Ultra experiment allegedly carried out by the CIA. Actually, there was only one unpleasant experience in the Murray study; it lasted about half an hour and could not reasonably have been described as "traumatic." Mostly the study consisted of interviews and filling out pencil-and-paper personality tests. The CIA was not involved.

> About 15 or 20 years ago a TV journalist named Chris Vlasto (if I remember the name correctly) looked up some of the other participants in the study and found that nothing had happened that was worth reporting in the media. My brief correspondence with Vlasto should be available in the University of Michigan's Special Collections library at Ann Arbor.

You can actually hear one minute of the recording of that half hour session with Ted Kaczynski on a series "A History of Persuasion" produced by WNYC, that was on their podcasts On the Media and The Stakes. It starts about 9:50 into the episode 2[2].

> AMANDA: It’s clear that this theory just isn’t true. This is not what broke Ted Kaczysnki. It’s not the reason he tried to kill James McConnell. And yet it’s totally taken off. It’s been in all of these books, there’s these articles, it was in the TV show “Manhunt,” about the Unabomber.
