Tmpfs Adding Case Insensitive Support For Wine / Steam Play & Flatpaks

My RSI was solved simply by tilting ethe keyboard the "correct" and "more ergonomic" way (negative tilt, instead of the asinine positive tilt that is still standard - even worse the keyboard makers still add feet to the wrong side of the keyboard for people to adjust their positive tilt...).

My wrist construction the positive tilt is beneficial. Fun of different wrist bone shapes. Really ideal would be feet on both side.. My resting hand position is kicked back naturally. Majority of population hand is either flat or kicked forwards at resting position. People who designed early keyboards some of them must have been like me so creating something that curses like 80%+ of the population with wrong way tilt.

Still, every person and every RSI is different, but taking the backspace and enter and shift etc away from where they'd make the pinky stretch is already a big improvement.

As long as it does not hit the thumb issue. That pinky stretch goes back to a historic one what height person was the original pc keyboard designed for horrible enough person of 6 foot tall. If you are under 6 foot on a standard keyboard you are going to be stretching thing at lot more than originally designed. How tall you are is a factor on how much you gain by moving keys to the thumb or not.

The so called ergonomics specialists tried to come up with one size fits all. Humans and one size fits all does not work.

Yes you don't solve RSI once you have it. Its live with it and it will change with time like it or not what you are doing give relief for now.

I wasn't going to reply again, just cause of too much posting, but there's a lot of misinformation in your post.

First of all the majority of typists were women. Men dictated and secretaries typed. I don't think ever in the history of mankind the average height of women was 6ft.

Second, the taller you are the worse the pinky situation - as your elbows are more far apart so your hand has a higher deviation, thumbs closer to the belly and pinkies closer to the numbers row. Unless your keyboard is places like 3ft forward. I should know, as my hands are bigger than the average for my height (and yes, I'm over 1.83m).

Third as I said the tilt was so new typists could see the labels in each key, this is a known fact.

Then, there is no way for someone to have a wrist that tilts the hand up. Only if they developed an impingement, biomechanically it can't happen, otherwise the wrist wouldn't be able to flex, only extend. Since the wrist is able to or supposed to move in every each way, the bones do not touch at a resting position (e.g. arm relaxed, hanging by your side). If your hand tilts the other way, it could be an impingement as I said, cysts or spurs, or (most likely) just general atrophy or shortened tendons (which can be resolved literally by exercising or stretching, respectively). Very rarely people may have campodactyly or something like it, that AFAIK can't be treated by stretching, but that is very rare.

Finally, RSI, tendynopathy and carpal tunnel syndrome all can be "cured". Extreme cases may need surgery, but the injury and the syndrome are qualified as such from continuous inflammation, to the point that the inflammation acts as an auto immune disease and "attacks" healthy tissue, causing more inflammation, through rest and NSAID 80% of cases are "resolved" in about six weeks.

If it is caused by cysts or arthritis or excess bone growth then yes, no way to fix once and for all. Only, sometimes, surgery or injections of whatever fluid they put to protect the bones for arthritis (was it HA? Can't remember).

Just to add, keyboards in typewriters were not expected to be touch typed, everyone assumed everyone would always "hunt and peck" - so no key press ever would be a stretch to any finger...

PC keyboard spacing comes after touch typing was a thing. Early mechanical typewriters you are right. Do note early mechanical typewriters for touch typing were also built for people with hands like mine. Like less than 10 percent of the population is going to type right so you can cherry pick the right people and this turns out to be completely wrong

The heavy load and kick of early mechanical typewriters that are your hunt and pick typewriters did have higher risk of RSI of course in two fingers. Yes 10 finger typing and machines designed for it comes out of how can we spread out this load so lower staff losses.

First of all the majority of typists were women. Men dictated and secretaries typed. I don't think ever in the history of mankind the average height of women was 6ft.

That correct. There is one very big problem. All early keyboards are designed constructed and tested by men no women involved. There are photos of lots of these design teams in existence the min height is 6 foot they are not even average to the male population heights.

Its not campodatyly. And its not a impingement. Another sideeffect of what I have is I have a hell of a time doing cricket bowling because my elbows at as straight as I can have them in fact have bend so can get called for throwing when I am not. The resting positions of by elbow and wrists is not in fact straight. This is also more common in men that women. Yes worst you look at those early keyboard developers phones and you see the non straight elbows.

Rest position of wrist is between two bone limits my issue is related to tendon lengths and its not 100 percent uncommon. Resting location(were muscles are relaxed) of wrist is between 10 degrees up to 10 degrees down due to tendon length with the wrist having full range of movement. So the tendon to the back of my hand for wrist are too short for my wrist to sit it rest straight mine sits at 15% So bending my hand forwards(in direction of palm) I cannot hit the bone stop of the wrist that way I come up short by about 3 degrees. Yes my elbow is about 15 degrees off straight as well but this is dumb luck these normally do match..

The bones in wrist limit movement most of the time more than the muscles and tendons do. If you were talking in joystick terms humans wrists have quite a big dead zone when you average it across the population for no movement has been done. Its a rare human that tendons to the wrist in fact have the hand sitting at the zero point due to being exactly the right length.

DumbFsck the shocking reality look at the design team photos of early touch typing keyboards be it PC/computer keyboards or mechanical typewriters
1 they are all men.
2 they are all over 6 foot. Quite a few of teams min height is 6 foot 4 when guessed from photo. So over 6 foot is being conservative..
3 about a third of them for sure from what you can see in the photos have 12 to 15 degree wrists up bends resting position
4 zero you can find with down wrist bends.
5 it gets worse if the ones that cannot be determined by photo what their wrist resting bend is 70% of the team could have upbends.
Yes this even includes the team making the classic IBM PC keyboard.

This absolutely does not match the average population but for some reason above is the average population who designed our modern day default keyboards core design.
These development teams really did not have diversity in testing and we are living with it.

DumbFsck lot presume incorrectly that since women used keyboards a lot it was designed for them when in reality this was not the case. Lot of people presume that back then there was check if tool fitted users this is before the idea of doing this was common. Yes time default keyboard design comes from it was more the user would alter to fit the machine not the machine fit the user. This also explains some of the early highly highly painful to use computer mice.

One of the reasons for tilting keyboard forwards is to reduce finger travel distance. Makes sense if your wrist has a 12/15 degree up resting position. The complete default keyboard is designed for up-tilled wrists and less than 20% of the population is that. Yes even a smaller percentage exceeds 10 degrees. We are talking people over 1 in 20000 that made up over 1/3 of the keyboard design teams(yes the 12 to 15 degree up angle). Its no surprise that the default keyboard causes some issues when you look at who in fact made that core design.

It was a fun thing it was why was it when I put my hands as it was diagrammed by the man user in the IBM PC manual was I perfectly good completely disagree regarding the recommend ergonomics. Then I find the staff photo of the IBM PC keyboard design team and hello person in that photo in IBM PC the manual is in that team photo and has the same angles as me. Then I dug deeper and found how screwed this is and that he was not the only one in the team photo like that.. At this point I already knew I was not the common type.

Most Eastern languages have the single case. There is no upper or lower case.

Mostly true, but one notable exception is Japanese. Like upper and lower case, Hiragana and Katakana are two different ways of writing the same letters. Also like upper and lower case, the letters descended from the same original forms and have similarities, but they have diverged more, to the point that you wouldn't know they were the same letter by looking at them.

Hiragana is used to write native Japanese words. Katakana is used to write "unofficial" words like onomatopoeia and foreign loanwords. Katakana can be used for emphasis in the same way we use all caps.

I couldn't find those photos you speak of. I only found one of Sholes sitting down and portraits of Souls and Gliddens. What I did find was an excerpt of a letter by Olivetti saying Thomas Edison was tall... Considering Thomas Edison was 5ft10 it is safe to assume Olivetti was short by today's standards.

If you can share the photos you speak of, I'd be very pleased.

1 in 20000 I can believe. I estimate much more, like actually 1-5% I know have shortened tendons (due to posture, usage of limbs, atrophy etc.

15% is like the limit of what is considered "normal" (and if you recall statistics well, about 67% of the population is "normal" or "average") so you are just about >1<<1.2 standard deviations from the mean.

I do still believe it could be fixed by stretching (of course depending on age and "mileage" or usage (take a picture of Devon Laratt with his arm extended as far as it can go, but in his fifties and after decades of armwrestling I doubt you can make it go straighter).

Also, iirc correctly from anatomy classes, having straighter arms is more common in men, women usually have a more pronounced angle - I'm not sure exactly what it was called, but it even had a name, but it had something to do with the proportion of shoulder width to hips (women have wider hips than men, men have broader shoulders, on average).


Also you are incorrect in that usually, for the average person, the tendons limit wrist movement. Being limited by the bones is often associated with pain and is provably due to hypermobility. Not necessarily bad hypermobility, could be benign, but still hypermobile.


By the way, I didn't mean that typewriters were designed with women in mind - I believe the makers of keyboards didn't have any ergonomics in mind at all (take for example those prototype typewriters that used piano keys, I can see that influencing the size more than any aspect of the human body) - what I mean to say is that the early typewriters were changed many times, a few of those times due to feedback from users (the big example being the qwerty layout having to do with typesetters and telegraph operators), so while I fully disagree that typewriters were "designed for men of tall height" (paraphrasing what you said), I don't think they were designed for women, but there were changes to the machines when rubber met the road and people started using them in numbers, and things could be changed for smaller people if that was the case.

I'd actually argue the size of typewriter keyboards was limited by technology - Christopher is said to have wanted one (before inventing it) so he could type contracts while he was on the train - so they wanted the size to be as portable as they could make wgile having cost not balloon out of control (if they were to make the linkages like Swiss watchmakers made theirs).

Also remember that papermills already were making paper in foolscap size, and if you cut foolscap paper in half you have approx. the same size as imperial Letter size. I fully believe this was also a constraint they had while making their typewriters.

So as wide as they need to have half a foolscap sheet fit it, as short in depth as they could, so it could fit in small desks and hand luggage (later with the "portable" models even a briefcase)


Another interesting tidbit of typewriting history is that they marketed it as not giving its users "telegraphist" paralysis and writer's cramp, as those other had put too much strain on their wrists, and typewriters were to be operated with movement basically only at the elbow.

Turns out that yeah, they were completely wrong. But it isn't like that was a rare occurrence right, just look at medical adverts for cigarettes...
