top 5 unsolved problems in computer science
-
My own pet peeve is UI components whose associated action is divorced from the components interaction feedback.
For example, a button that seems visibly pressed (even lights up! Maybe there's even audio or haptic feedback!) but once you release, nothing actually happens because you were supposed to press it or hold it down for slightly longer.
This even happens with physical controls: in some elevators you can press a floor button such that it lights up momentarily, and even beeps, and yet the elevator doesn't register the command and you have to press again, longer.
I've actually noticed this exact thing with elevators before... I was kind of amazed the beep and light were hooked up completely independently from the actual floor selection logic.
It sort of makes sense that the light in the button would just be hooked directly up to the button contacts. The computer would then be polling the buttons separately and it's possible to miss a button press...
These sorts of buttons shouldn't need a debounce period since pressing any of them a second time doesn't do anything. If the buttons were interrupt based, this probably wouldn't happen. -

I wanna... I have a dream where computers don't create their own problems to solve and are not used to shoehorn in the desires of rich people and give us a future that we didn't ask for.

Discord steals focus 3 separate times on startup. It's so goddam infuriating. Battle.net does at least twice.
Steam does as well.
I found out recently that KDE has a "Focus stealing prevention" in their settings and it has been glorious.

wrote on last edited by [email protected]I have this experience with a certain type of pedestrian traffic light "button".
I quote button, because nothing physically moves when you press it. I'm not sure if it registers pressure or heat, but you don't even feel anything move when you press it.
Usually when you press the button, a red text lights up on the button, telling you to wait. This text gives you feedback that the button registered your press, and the traffic light will schedule a green light for you.
However, sometimes you didn't press hard enough, and the text doesn't light up. Simple solution: press harder.
But there is a scenario where it doesn't matter how hard you press, the button won't light up. You keep staring at it, while slamming the damn thing with the fury of a Hulk wealding Mjolnir. Still, nothing lights up. The reason: the light instantly went green, so it never needed to light up the text telling you to wait. And all that time slamming your fist on the button, could have been spend crossing the intersection. Instead you have been standing there, looking like a drunk person having a fistfight with an inanimate object.

Wow, getright! That's a throwback. I used that in the 90s.
On linux I use aria2c for similar tasks. It can resume http downloads, as well as split them up into multiple threads for faster downloading.
It's cli-based and powerful (therefore perhaps a bit confusing at first), but there are UIs for it as well for a more get-rightty experience.
I think jdownloader also has some application here, though it's mostly for getting things from those ad-filled file hosting sites frequently used by those on the high seas
Why would you multithread it except for heaving mutiple paths of entry to your home connection or you are getting a throttle from the file hoster?

Basically that. I don't do it much anymore, but it used to be helpful.

If only there was a way to copy text, and then paste it someplace else. Sigh... unsolved problems.
Yeah, really unfortunate that that's not possible. Always having to take a screenshot and then type out letter by letter what's on the screenshot, that can be quite annoying.
But even if copying text was possible, the reason people post pictures of text is to give proper attribution, but also to distance themselves from the content, so that it's clear that they don't necessarily hold the exact same opinion or that they might not have all the knowledge to defend the statements in the post.
Cross-posting could fill that same roll without screenshotting text.

If only we had some way to reference an original source. Something like a figurative link, if you will.

That would be cool, but human brains are weirdos. If you're already copying text, you could've edited or annotated it, for example. For example, if it's an opinion you don't entirely agree with, you might feel obliged to say so, because you have the ability to do so when it's a text post.
If you want to call that irrational, I'm not arguing against that. I'm just saying it's the reality we live in and I'd like to have tooling to deal with that better, because I would also prefer text to not be screenshotted.

Don't most browsers support this?
but not all web servers. often it's disabled
Oof, that's unfortunate. I can't say I've run into this problem though.

I recently wanted to send a file from Linux to an old tablet over Bluetooth. Can't be done apparently. I can send it to my phone, a windows laptop can send it to the tablet, but my Linux PC apparently can't. Still baffled about it.

Ooh! I need to look that up.

this is not a defined thing in markdown, just the markdown renderers of some clients do it
This here is apparently the original source of the markdown specification, and there it clearly says that this is the correct behaviour: https://daringfireball.net/projects/markdown/syntax#list
Ordered lists use numbers followed by periods:
- Bird
- McHale
- Parish
It’s important to note that the actual numbers you use to mark the list have no effect on the HTML output Markdown produces. The > HTML Markdown produces from the above list is:
<ol>
<li>Bird</li>
<li>McHale</li>
<li>Parish</li>
</ol>If you instead wrote the list in Markdown like this:
- Bird
- McHale
- Parish
or even:
- Bird
- McHale
- Parish
you’d get the exact same HTML output

hmm, you are right. it's not actually a bug in the renderer then

wrote on last edited by [email protected]The only difference to the standard that I see is that the standard says it should be 1,2,3,4,5, while at least for me it renders as 5,6,7,8,9.
But that's probably because it doesn't render as HTML and thus doesn't rely on HTML to do the numbering.

Applications that steal focus more than once in their startup are the real devil

My other pet peeves besides these:
- Android locking screen a second before I jab the screen, every single time
- YouTube app. Android and smart TVs. What's wrong with it? (Vague overall gesturing) It's garbage. How is one of the biggest tech companies in the world able to ship this and expect people to pay money for subscriptions is beyond me.

Android in general is trash.
