This is also my experience. I'm not a DJ but I perform live electronic music using various MIDI controllers. If I quickly want to add or remove a sound, like a kick drum, to/from the mix, a slider is best. If I need fine control o

I programmed something like that back in 1999: https://kuederle.com/university/fur/improvedtext.jpg Each hair consisted of four segments. All segments were sorted, then drawn back to front. Each segment was drawn

Some larger retail stores in Germany ask you for your postcode during checkout, presumably to learn a bit about their customer base. I don't mind telling them mine, there are about 16K people with the same postcode. But I'm pretty

It's funny how every TUI developer eventually stumbles over Unicode and then handling international characters and emojis correctly turns into its own project close to the same scope of (or even bigger than) the original TUI project. I

I tried the model the article links to and it was so refreshing not being denied answers to my questions. It even asked me at the end "Is this a thought experiment?", I replied with "yes", and it said "It's fun

Completely agree on not setting a deadline, it will likely lead to disappointment as we tend to set unrealistic deadlines anyway, even more so for personal projects which rely on having time off of work and other responsibilities. I would e

When I see these kind of readability-decreasing optimizations in code reviews, I always push back. Almost always, that same Go code queries some other service over the network or loads data from the database, or similar, and nobody will eve

Chrome Developer Tools allows this. There's a button in the Source tab to deactivate breakpoints from debug statements. The button looks like an arrow cut in half.

To my knowledge, there is no specification for monospace width. Applying the East Asian Width attribute as a proxy does not work reliably. So in my opinion, it is all a matter of agreeing on what's reasonable while keeping it simple. I

I spent a lot of time on this topic (see https://news.ycombinator.com/item?id=37048434 ). Feel free to get in touch and discuss. I'm happy to help.

I spent quite a bit of time coming up with an algorithm that gives me the correct width for any Unicode character, including emojis [1]. The reality is much more complicated than what wcwidth does and using the East Asian Width attribute wi

The library I posted uses colour information. It won't map to greyscale first.

And if you just want to go by the pixel data, look into "perceptual hashing". https://github.com/rivo/duplo works quite well for me, even when dealing with watermarks or slight colour correction / sharpe

I was in Madagascar in 2019 and while some people have top notch fiber connectivity at home, most people only have Facebook. It's free on mobile phones while any other internet traffic costs money which most people can't afford. A

These stories always bring back that anxiety I got as a teenager when I read Kafka's "The Trial". You're guilty and being punished but we won't tell you why, what you did, and there's no way to appeal. Back the

You're definitely right in that children are very different from another. In my experience, however, fear almost always comes from a previous bad experience or it transfers from other people. I've done the "first time at the

What would be the proper punctuation if you rearranged the sentence slightly? Dr Johnson kicked a large rock and said, “I refute it thus.”, as his foot rebounded. Is the period redundant? Or the comma after it? None of them? This looks al

In Germany, almost everyone refers to it as the Biontech vaccine. For obvious reasons. I would even go so far as to say that most people here don't realize it's the same as the "Pfizer vaccine". (On the other hand, the M

I've worked with D3 for many years. It's great for small, quick visualizations. But I've more than once reached its limits. For one, anything more complex (e.g. custom axis labels that don't overlap) requires you to roll

Maybe I'm assuming too much but it wouldn't occur to me to let tx.Commit() depend on the outcome of another connection (here: db.Query()). Either use tx.Query() (which I guess is partly what you're advocating) or put db.Query

Trying to figure out how much it would cost the customer to develop the same functionality is probably the best strategy (and suggested by most posters in this thread). I would add that the customer may not come up with a detailed estimate&
