  • For me, video is rarely the form that I want to consume any content in. It’s also very obnoxious if I’m on a slow data link (e.g. on a slower or saturated cell phone link).

    However, sometimes it’s the only form that something is available in. For major news items, you can usually get a text-form article, but that isn’t all content. I submitted a link to a YouTube video of a Michael Kofman interview the other day talking about military aid to a Ukraine community. I also typed up a transcript, but it was something like an hour and a half, and I don’t know if that’s a reasonable bar to expect people to meet.

    I think that some of this isn’t that people actually want video, but that YouTube has an easy way to monetize video for content creators. I don’t think that there’s actually a good equivalent for independent creators of text, sadly-enough.

    And there are a few times that I do want video.

    And there may be some other people that prefer video.

    Video doesn’t actually hurt me much at this point, but it would kind of be nice to have a way to filter it out for people who don’t want it. Moving all video to another community seems like overkill, though. Think it might be better to have some mechanism added to Threadiverse clients to permit content filtering rules; I think that probably a better way to meet everyone’s wants. It’d also be nice if there were some way to clearly indicate that a link is video content, so that I can tell prior to clicking on it.


  • One thing that I found out was that as “most-Minecraft-like” games for Minetest, there’s apparently Voxelibre (renamed Mine Clone 2) and Mineclonia (fork of Mine Clone 2). Just out of curiosity, if you looked at both, what made Voxelibre particularly appealing relative to Mineclonia?

    I’ve played Minetest, even contributed some code IIRC, but that was some time back, haven’t ever played the derived games. Kind of thinking about maybe giving it a go now that there’s apparently more there.




  • You can still get a few phones with built-in headphones jacks. They tend to be lower-end and small.

    I was just looking at phones with very long battery life yesterday, and I noticed that the phone currently at the top of the list I was looking at, a high-end, large, gaming phone, also had a headphones jack. The article also commented on how unusual that was.

    Think it was an Asus ROG something-or-other.

    An Asus ROG Phone 8 Pro.

    That’s new and current. Midrange-and-up phones with audio jacks aren’t common, but they are out there.

    Honestly, I’d just get a USB C audio interface with pass-through PD so that you can still charge with it plugged in and just leave that plugged into your headphones if you want to use 1/8th inch headphones. It’s slightly more to carry around, but not that much more.

    Plus, the last smartphone I had with a built-in audio DAC would spill noise into the headphones output when charging. Very annoying. Needed better power circuitry. I don’t know if any given USB C audio interface avoids the issue, but if it’s built into the phone, there’s a limited amount you can do about it. If it’s external, you can swap it, and there’s the hope that their less-limited space constraints meant that they put in better power supply circuitry.





  • locking down the Windows kernel in order to prevent similar issues from arising in the future. Now, according to a Microsoft blog post about the recent Windows Endpoint Security Ecosystem Summit, the company is committing to providing “more security capabilities to solution providers outside of kernel mode.”

    So first off, from a purely-technical standpoint, I think that that makes a lot of sense for Microsoft. Jamming all sorts of anti-cheat stuff into the Windows kernel is a great way to create security and stability problems for Windows users.

    However.

    I don’t know if my immediate take would be that it would permit improving Linux compatibility.

    So, from a purely-technical standpoint, sure. Having out-of-kernel anti-cheat systems could make it easier to permit for Linux compatibility.

    But it also doesn’t have to do so.

    First, Microsoft may very well patent aspects of this system, and in fact, probably has some good reasons to do so. A patent-encumbered anti-cheat system solves their problem. But that doesn’t mean that it’s possible for other platforms to go out and implement it, not for another 20 years, at least.

    Second, it may very well rely on trusted hardware, which may create issues for Linux. The fundamental premise of a traditional open-source Linux system is that anyone can run whatever they want and modify the software. That does not work well with anti-cheat systems, which require not letting users modify their local software in ways that are problematic for other users. My Linux systems don’t have ties up and down the software stack to trusted hardware. Microsoft is probably fine with doing that, on both XBox and newer trusted-hardware-enabled Windows systems.


  • Words per minute meaning literally words or characters?

    Words. Well, IIRC in tests it’s something like an abstract word of fixed length, something like 5 characters or something, as that’s the average word length in English. Like, it doesn’t mean you’re typing “antidisestablishmentarianism” over and over, one word each time.

    kagis

    Yeah:

    https://en.wikipedia.org/wiki/Words_per_minute

    Since words vary in length, for the purpose of measurement of text entry the definition of each “word” is often standardized to be five characters or keystrokes long in English,[1] including spaces and punctuation. For example, under such a method applied to plain English text the phrase “I run” counts as one word, but “rhinoceros” and “let’s talk” would both count as two.

    Karat et al. found in one study of average computer users in 1999 that the average rate for transcription was 32.5 words per minute, and 19.0 words per minute for composition.[2] In the same study, when the group was divided into “fast”, “moderate”, and “slow” groups, the average speeds were 40 wpm, 35 wpm, and 23 wpm, respectively.

    With the onset of the era of desktop computers and smartphones, fast typing skills became much more widespread. As of 2019, the average typing speed on a mobile phone was 36.2 wpm with 2.3% uncorrected errors—there were significant correlations with age, level of English proficiency, and number of fingers used to type.[3] Some typists have sustained speeds over 200 wpm for a 15-second typing test with simple English words.[4]

    Typically, professional typists type at speeds of 43 to 80 wpm, while some positions can require 80 to 95 (usually the minimum required for dispatch positions and other time-sensitive typing jobs), and some advanced typists work at speeds above 120 wpm.[5] Two-finger typists, sometimes also referred to as “hunt and peck” typists, commonly reach sustained speeds of about 37 wpm for memorized text and 27 wpm when copying text, but in bursts may be able to reach much higher speeds.[6] From the 1920s through the 1970s, typing speed (along with shorthand speed) was an important secretarial qualification, and typing contests were popular and often publicized by typewriter companies as promotional tools.

    Stenotype

    Stenotype keyboards enable the trained user to input text as fast as 360 wpm at very high accuracy for an extended period, which is sufficient for real-time activities such as court reporting or closed captioning. While training dropout rates are very high — in some cases only 10% or even fewer graduate — stenotype students are usually able to reach speeds of 100–120 wpm within six months, which is faster than most alphanumeric typists. Guinness World Records gives 360 wpm with 97.23% accuracy as the highest achieved speed using a stenotype.[7]

    So it’s not a typo or whatever, if that’s what you mean.

    Because 3 - 4 words per second seems a bit much to me and whoever talks that fast?

    It’s pretty fast, but then you’re talking about a professional text-entry person using the fastest plain-text entry mechanism we know about in a speed test. I’m sure that that’s not something demanded of a stenotypist in a normal real-time transcription session.

    My guess is that you probably could still make practical use of it if you didn’t need real-time transcription by doing a recording and then playing back with software that can do time stretching to accelerate the rate of playback; you could transcribe more-quickly.

    'course, automated transcription’s getting better too, and that might also be an answer on that front.



  • I also have the back propped up like you mentioned with the built in lifts

    Ah hah!

    Yeah, there are some ergo keyboards that have that “reverse tilt” built in. They’re aimed more at being easier on the wrist than at trying to permit for long nails, but they do exist.

    e.g.:

    https://matias.ca/ergopro/pc/

    I also have carpel tunnel

    That’d be an argument for a keyboard, like, a mechanical one where you don’t bottom out the keys on press, and then training yourself to not bottom them out, which is a big argument mechanical keyboard fans have for theirs versus rubber dome keyboards. And you need a fair bit of key travel for that, yeah. Hmm.


  • Hmm. Interesting.

    If you don’t mind me asking, could you describe what alternate keycaps were used? Like, taller keycaps in the front, shorter in the back? Like, I still think that the amount of keytravel would be a negative, but maybe the issue is that the long nails descend into the keyboard given the normal position of a hand typing, and basically changing the angle improves that.

    If that’s the case, I’m wondering whether maybe it’d be possible to change the angle of the keyboard as a whole. Like, either use an external keyboard propped up differently, tilting away from the user, or a laptop with the front part of the base shimmed up to tilt away from the user.


  • Hmm. That’s an interesting problem to have.

    On one hand, I can’t suggest a great alternative, but man, silicone keys…I guess if they work for the author.

    Stenotypists – people who have to professionally do very high-speed text entry – do use these dinky specialized keyboards that IIRC from a Japanese-language one – I think that there were multiple Japanese layouts – can only have a home row or something. I think that they use chording or something. I don’t know if that might address it, but learning one would be a huge change. Also, I have no idea what keys they can output…given that they’re highly-optimized for text entry, they might not be able to do weird symbols.

    goes looking

    https://en.wikipedia.org/wiki/Stenotype

    A steno machine, stenotype machine, shorthand machine, stenograph or steno writer is a specialized chorded keyboard or typewriter used by stenographers for shorthand use. In order to pass the United States Registered Professional Reporter test, a trained court reporter or closed captioner must write speeds of approximately 180, 200, and 225 words per minute (wpm) at very high accuracy in the categories of literary, jury charge, and testimony, respectively.[1] Some stenographers can reach up to 375 words per minute, according to the website of the California Official Court Reporters Association (COCRA).[2]

    Hmm.

    Looking at the key layout there, and here:

    https://stenokeyboards.com/

    …it looks like English-language stenotype keyboards don’t just use a single row, but rather two or more rows. So that’s probably out.

    There’s apparently a second chording layout, the “palantype” layout, but that also doesn’t do only one key per finger:

    https://www.openstenoproject.org/palantype/tutorial/2016/08/21/learn-palantype.html

    There are dedicated chording keyboards that do use only one key per finger, though.

    https://en.wikipedia.org/wiki/Chorded_keyboard

    That has some examples of one-key-per-finger keyboards, like the BAT keyboard (well, that has three for the thumb, but given that you hit those with the side of the thumb, I assume that it’d be okay with long nails):

    https://www.infogrip.com/bat-keyboard.html

    The problem is that (a) the BAT is discontinued and (b) you really don’t want a one handed keyboard, which is what the BAT does…it’d be better to have a two handed chorded keyboard, or you’re taking half of your fingers out of the picture.

    EDIT: Here’s an open-source, two-handed chording keyboard, the Ialboard, based on the discontinued DataHand keyboard. I’m not sure that it’d work with very long nails in its current form – they might collide with the structure of the keyboard – but it’s 3d printed and I’m pretty sure that if the format doesn’t work as-is, a tweak to the 3d-printed keys would permit for arbitrarily long nails. Just need to create a space for 'em.

    Gonna need some serious keyboard re-learning, though.

    EDIT2: Here’s another two-handed chording keyboard with one input device per finger, the CharaChorder. It uses an analog D-pad under each finger. I think that it’d have space for long nails as-is. It does have separate arrow key and mouse control sticks, and I’m not sure if those, given the placement, would be an issue for long nails. I’d imagine that if one were determined to work around that with an external mouse device and – if you use arrow keys enough to need it; I rarely do – maybe some dedicated arrow key keyboard, though I’d think that having the arrow keys in vim-style hjkl-style layout might be preferable to the inverted-T layout that seems common. I don’t know whether the barrel connector’s positioning there would be an issue, though the positioning of that is obviously not critical to the keyboard, and I imagine that if it is an issue, with a bit of work, one could relocate it.

    EDIT3: It looks like there’s another DataHand-based 3D-printed keyboard besides the above-mentioned Ialboard, the Svalboard. Same argument as with the Ialboard – I’m not sure that it’d be usable with long nails as is, but I’m pretty sure that that design could be modified with approprately-different key shapes to permit long nails to extend through a gap. You can apparently buy the thing in kit form, 3D-print it, so I figure that if someone wants to make a “longnail” variant of a few of the 3D-printed parts, that’d probably be a pretty easy keyboard to start from.

    The downside is that I don’t think that – unlike the above CharaChorder – this comes with a travel carrying case, which might be important if you’re a laptop user. I guess it’d probably be possible to craft something with foam and a shell, but that’s not off-the-shelf any more.



  • Well, I don’t think that there’s going to be a way to narrow it down just from that. Can maybe suggest some things to try.

    Segfaults happen when an app is trying to write to memory that it shouldn’t be. It tends to indicate either a bug (which shouldn’t be the case at the application level, given multiple applications doing it), or corrupt memory.

    INTEL i7-4790

    Well, it’s not the recent 13th+14th gen Intel hardware problems; I had two processors produce corrupt memory via that route recently. That’s an ten-year-old processor, though.

    Memory would be an obvious thing to blame, but memtest not hitting it is an argument against that.

    Proton-related stuff – Windows games running under Steam – might use a fair bit of memory. Do you have swap space, maybe?

    $ grep ^SwapTotal /proc/meminfo 
    SwapTotal:        999420 kB
    $
    

    I can imagine a swap device corrupting memory. If you’re using any swap, I’d probably do a fresh boot, use sudo swapoff -a to disable swap space, and then try your repro case with proton.

    It’s possible that there’s some kind of kernel bug relating to memory allocation that you’re tripping, I guess, but you’re running an up-to-date Arch, so I assume that you’ve got a recent kernel, and you’re saying that this has been going on for “some time”. That would be consistent with problems continuing to happen once the problem occurs on a given boot and a reset making things go away, I suppose.

    I guess it could hypothetically be a problem with the Nvidia drivers…if the Proton games you’re playing are 3d games, that might be tripping it.

    A game might also be stressing the CPU, triggering temperature or other issues. The stress utility would let you generate sustained CPU load on cores (--cpu), maybe see if that reproduces your problem.

    Proton games might be loading the GPU…I don’t know of a good way to artificially generate load there, unfortunately.

    You could try checking the kernel log for any errors preceding the segfaults in the kernel log, maybe when you’re running that Proton game; any issues there might give a clue.
