You're suggesting that the locale should be fixed when the filesystem is created?

Unicode has rules whether letters are the same. These rules are locale independent. It doesn't matter whether French or German has different [..] rules.

It will matter if you ever copy files from a filesystem with a French locale to one with a German locale.

There's an expectation that if I tar up a group of files and send it to another user, they can untar it to get the same set of files. Case-insensitive filesystems break that expectation. Having the flavour of case-insensitivity vary depending on the target filesysterm's locale even more so.

Similarly, would a human expect "MyNotes" and "My Notes" to be the same file? If so, should the filesystem also handle such cases?

What about "MyNotes!" or " MyNotes"?

Do humans consistently consider filetypes/filename extensions to be part of the name or not? Should "MyNotes.txt" be the same file as "MyNotes.rtf"? What about "MyNotes.txt.txt" or "MyNotes.1.txt"? Should filename extensions use the same rules as filenames?

humans don't see case as significant

Humans *do* see case as significant. Do the names ExpertsExchange and ExpertSexChange look the same? Should they be the same file?

Can you come up with an algorithm that accurately and predictably determines when humans will or won't see two names as the same?

If the name uses an alphabet the user isn't familiar with, can the user accurately determine which lower-case glyph matches which upper-case glyph, in the same way that the computer does?

What if the user or name uses a language different from the one the algorithm assumes? Are the rules for lower/upper matching the same across all languages? Should the algorithm use the locale setting?

the binaries fit on a single 3 1/2" HD disk

If you were installing it to a hard drive. Back in the day, some people still ran everything on their floppy drives.

"HD disk" in grandparent post surely meant High Density floppy disk, not "Hard Drive disk" or "hard disk drive" (HDD).

That's ignoring Vernier Acuity, which is a very important effect on displays where the pixels form parallel lines, i.e. pretty much every modern electronic display. It gets down to 0.13 arc minutes, which is why there are several replies pointing out that your theory doesn't match reality, even for people with worse than average vision.

And this figure of 2190dpi? That's 3 significant figures, computed from something that was given to only one significant figure (0.4 arc minutes). You can't do that, and it should be a huge red flag that the source article should not be taken seriously.

Firefox supports 60fps if the video is encoded in WebM (VP9) which only happens on Youtube if it has enough views

Google could have added support in the Flash player

I get 60fps on test videos with single-digit views, using RHEL 6.4, Firefox 17.0.7 ESR and Flash 11,2,202,327.

Although the video options only present e.g. 720p rather than 720p60, selecting 720p gives 60fps. Selecting 480p gives 30fps. The same video encoded at 30fps before upload and viewed in 720p shows the difference very clearly. I suspect it's something to do with the old version of Flash.

For reference, I also tested with Windows 7, Firefox 33.0.2, Flash 15.0.0.152, and 720p and only get 30fps.

Some of it is learned through practice, but all of it isn't.

The meaning you intended to convey was probably "not all of it is". Otherwise, the literal meaning contradicts the first part of the sentence. What came up with that phrasing - your conscious or unconscious mind?

I've noticed that the faster I write, the more likely it is my writing will contain homophones. I presume that the faster I write, the more my unconscious mind gets used for the task, and it places more emphasis on sound. Or there's a sound buffer and a letters/word buffer working in parallel, with the former usually taking precedence, but at speed it gets filled too quickly, so the fallback is to the sound buffer.

Hmm, I think you have a few things wrong and/or misleadingly stated.

In the early 1980s Acorn evaluated CPUs for their next-generation product. 80286 was released in 1982 February and was readily available on the market so there was no need to get Intel's cooperation to evaluate it. But, Acorn did want to license the 80286 core and make changes to it, which Intel rejected. All the evaulated CPUs were deemed inadequate, so in 1983 October Acorn started development of Acorn RISC Machine.

The goal of the ARM architecture was high performance. (On production release it out-performed the still-current 80286.) The device was simple because of the limited design resources, and therefore low-power, but for it to be quite as low power as it turned out to be was an entirely unexpected accident.

Apple officially became part of the the ARM project when Acorn spun off ARM Ltd in 1990 November, by which time the 80486 was on the market. Apple's interest was to continue development of low-power CPUs for their Newton handheld, for which the 80x86 line was unsuitable.

One possible reason that things aren't going according to plan is that there never was a plan in the first place.
