1: You could absolutely use gyro/accel for detecting taps, but for proper pressure sensitivity (i.e., changing pressure in the middle of a stroke), there's not much you can do except have a pressure sensor. It's theoretically

Currently it's not quite at the level of graphics tablets, but it's not too far off, and I think there's quite a bit of potential to improve it using similar techniques [1]. In terms of absolute accuracy, I measured an averag

I knew it would have an effect (most of the literature for similar projects just uses global shutter cameras for this reason), but wasn't sure how significant it would be. It turned out to be small enough that it usually wasn't su

I should point out that I'm not the first person to use camera tracking for this [1], but to my knowledge there hasn't previously been a serious attempt to combine it with inertial or pressure sensors (which are both necessary for

Ironically, that's a fantastic example of just how unachievable full test coverage actually is in most projects. > By comparison, the project has 590 times as much test code [as program code].

I think you are confusing Gleam with Gren (a fork of Elm)?

I think there are two main reasons: - Early versions of SQL were actually called SEQUEL (Structured English QUEry Language). - Sequel is just much easier to say than SQL, especially within a sentence.

To be fair, 12/20 _is_ closer to 2/3 than 1/2.

Interesting read. I was very surprised by the mention of adding editing features at the end. That sounds like a proverbial black hole of potential feature requests and "bloat".

Counterpoint: Everyone had to "get used to the patterns" for the first programming style they learnt (even if they've been programming long enough to forget that). That shouldn't be a reason to avoid learning a different

I wouldn't describe blender as following this formula. The only thing they sell (last time I checked) is blender studio, which as far as I'm aware is more just another way to donate while getting some things in return.

30+ second compile times is definitely not something inherent to statically typed languages. 200ms is rare, but plenty of static languages manage <5s for large projects and much less for small ones. Not to mention that a good IDE will in

That's exactly why the author says to check for warnings in CI. Most warnings will be noticed and fixed by the dev before pushing, and the rare ones that get missed will be caught in CI before merging.

Visual studio does give a fairly detailed explanation of what was compiled each time, in the output>build view.

Also worth noting that just about every javascript engine uses ropes internally to represent strings (most of the time). https://docs.google.com/document/d/1o-MJPAddpfBfDZCkIHNKbMiM...

It sounds like you'd be much more comfortable in an IDE with a debugger. Any reason you're not using visual studio or clion etc? Even vscode should be able to give you a decent debugging experience if you're not doing anythin

You completely missed my point. You aren't "the other party" once you start making claims of your own. "I can assure you that caste had absolutely nothing to do with OPs election..." If your argument was just "

But you are also making your own claim, by asserting with absolute confidence that caste-based discrimination doesn't exist. If you were just questioning the reasoning of the author, then sure, the burden of proof would be with them. A

I find that pure functional loops with reduce or fold often get a lot harder to read/write as soon as you have more than one variable to keep track of. Imperative loops don't really have this problem.

Windows is particularly odd, because the file explorer menus are so similar that you wouldn't see the difference if you weren't looking for it.
