Apart from the social media and streaming stuff: - Spectroid: A spectrum analyzer to help me identify "that annoying sound I hear" or "what's wrong with the sound in this place?" I'm not good at ignoring sound, but it helps me when I understand something about it, like "oh, that's a 10 khz harmonic" still annoying but slightly less. - DiggieDog: Gopher client, extremely fast, good for when I'm somewhere with REAL bad…

How could an app ("Ulysse Speedometer") be better at measuring the vehicle speed?? This seems so wrong!

Vehicle speedometers are factory made to display wrong info. I believe they add about 10% to your actual speed.

The reason is error-margin of speedometers, it's about 10% so they err on the side of caution.

Do you have sources for this?

Even if this is not just urban legends, a speed read from GPS data on a phone can only be much worse

Off topic but this is a real gripe of mine - analogue speedos that go all the way up to 240 kmph (~150 mph). I am only ever going to do half that speed, so why not just make the dial go to only 120/(80) and give the needle (and me!) twice as much precision!

You probably would better like a digital display that shows a number instead of a needle

I created a simple browser extension to help me organise my links. It solves a problem I had where there was a middle ground between keeping a tab open to read later and saving something to my bookmarks. It's under 200 lines of JS, not available on the Webstore and not complicated (or even well-written) at all, but it's a nice feeling to use a little piece of software I wrote that's purely customised to my specific u…

Care to share this? - I’d love to see how you approached this

Just to save the time for others, NIOSH Sound Level Meter is iOS only

Which makes sense, because it's reasonable to test every iPhone model and the microphone qualities. Less so for every possible android device.

Some cars also use unevenly spaced tick marks on an analog dial. Nice in that it gives you the sweep needle and range of scale without overly compressing the range of most interest.

Analog tachometers for race cars do/did the the same thing:
