@nafmo uwsgi has a minimal example in their docs. Uwsgi is the thing that runs python, imports your script, and calls a function in it once per request. You only need to provide that function.

Have a look here: https://uwsgi-docs.readthedocs.io/en/latest/WSGIquickstart.html

@nafmo wsgi is pretty much the standard these days. If you just want to handle raw requests yourself, cgi style, you can just use a bare python script with a wsgi runner like uwsgi, which requires no python code beyond a single function definition.

@lauren I found that funny too, both on yt and here on the fediverse. Reading that press release, I saw a company that was badly scared of one of their products burning down someone’s home, and that clumsily tried to prevent that.

Then on the other side I saw a bunch of people who were traumatized to hell by hardware manufacturers from HP to cricut and as a result had absolutely zero chill. A shitstorm ensues.

@azonenberg @jpm I think the feeder setup time is a big issue for one-off prototypes. If you have some odd component like a 9k1 resistor on the board once, placing it by hand is faster than setting up a feeder. At the cost of even the Lumen’s feeders, having a couple decades of E24 already on feeders is very expensive.

@monk @fluepke passports contain an anglicized variant of the name, but only in the machine-readable data area , that’s the big block of characters at the bottom. That data is hard to understand for some people.

Also note that all these protocol messages are never sent in the plain. They get tunneled over TLS, so on top of breaking all of signals DH-key exchanges, you'd first need to break a bunch of TLS connections too.

@soatok @risottobias @dalias @khm @ambiguous_yelp @sammi @joelanman Maybe it's worth noting at this point that signal is currently in the process of implementing a hybrid protocol for key agreement [1].

@soatok @risottobias @dalias @khm @ambiguous_yelp @sammi @joelanman

Another point worth noting is that the way they implemented PFS in signal's ratchet, it's not like you could compromise a session by breaking a single key exchange. Instead, in a hypothetical store-now-decrypt-later attack you would have to have a (gapless!) history of all traffic in either direction between two devices since they established contact, and you'd have to crack thousands of key exchanges.

I’ve just finished watching Pantheon, a US-made animated sci-fi series, and it was great. I’d highly recommend it if you’re into sci-fi. The writing was very good, it builds intelligently and respectfully on previous works in the genre and the animation’s visuals are great with some highlights that would not look out of place in a work by Satoshi Kon.

TIL that you can just watch cosmic rays hit the Superkamiokande experiment's giant (30m diameter) water tank 1000m below the Japanese alps in real time online:

@0xabad1dea Tge only reason I could imagine for this waste of engineering effort was that they have a massive engineering headcount, and those teams full of people were basically making up stuff to do so they don't get fired.

@0xabad1dea This is actually one of the reasons I switched away from Spotify. Out of nowhere, they would twiddle with the UI of their (android) app every few weeks. They would constantly change little things, continuously re-inventing what winamp did good enough in like 2007. They would never improve things by a lot, but sometimes-very annoyingly-make things slightly worse.

@slothrop @quixoticgeek While they are rare in the west, some state of the art rice cookers for the asian market are pressure cookers (sometimes even with induction heating!). They usually have a bunch of non-rice cooking programs. At least in the western country where I live, I think you tend to not see these mostly because they're too upmarket for most people to stomach the cost.

@nflux IIRC the reason that fans usually have an odd number of blades is that you want the number of blades and the number of struts fixing the fan hub to the casing to be coprime to each other, because that spreads out the acoustic emergy of the fan blades passing the struts the widest and avoids concentrating it into a single noisy tone.

For a freestanding wind turbine that should not matter.

"Optical side-channel attacks on bus stop signs" was certainly not on my academic bingo card today 🤣

On that #firefox feature that a lot of people are getting very upset about at the moment. Without even getting into the whole differentially private aggregation thing,

this is only going to affect someone in the first place if they (1) don't have adblock on and (2) click on the ad? like, in the case when their privacy is fucked already and AFAICT all #mozilla does is to make it slightly less fucked?

This weekend, I built a little portable soldering kit out of my old soldering station, powered from a Makita tool battery. I made this thing to help with maintenance of our bicycles' electrical systems, so I can solder right on our bicycles without running cables.

You can download STLs and OpenSCAD models on Printables, link below.

@gunstick @rberger @ja2ke Yes, there are some techniques. Most of them involve mechanically moving or vibrating some optical component such as a diffuser. To me, they seem too complex compared to buying a couple low-pressure sodium bulbs.

@rberger @ja2ke That might work. The reason you want a narrow spectral peak in the first place is that you want the background to be about the same brightness as the foreground so it doesn't swamp out the color image, but you want to concentrate as much of that yellow light energy as possible inside of the matte image filter's passband while keeping that filter as narrow as possible because making the filter wider will mess up the color image.

@rberger @ja2ke LEDs have a substantially larger bandwidth than a sodium vapor lamp, but if they are too broadband depends on how narrowband their filters in the video are. You're right in that you definitely want a straight yellow/red/whatever LED instead of a phosphor-converted one, as the PC ones have much broader bandwidth, and usually have a peak of the original blue or purple showing through as well.
