  • I think CloudFlare uses lava lamps because it's a cool story, but there are ways you can get truly random bits from other things, like this. Generally, you want to have some sort of physical process going on that provides random entropy, because CPUs by themselves can only produce pseudorandom numbers. For example, random.org uses atmospheric noise, which is random and unpredictable when you look at very tiny variances. You can also use, e.g. a super sensitive Geiger counter to measure random bits of radiation, or if you shoot photons at a semi-reflective surface, sometimes they go through and sometimes they reflect. For the type shown here, though, the most common kind of noise they use is from quantum effects relating to transistors, as far as I know. This is an actual source of randomness, so if it's done right it can be just as good as lava lamps or Geiger counters or whatever.


  • I might be wrong about this but my understanding is that on Linux you'd pipe the output of this in somewhere and tell the kernel to use it for entropy, and if it gets insufficient entropy it realizes this and starts producing random bits slower. So like normally the Linux kernel samples mouse movements for randomness, and so it makes more random bits the more you jiggle your mouse. These hardware RNGs are best used for headless servers that don't have as reliable entropy at their disposal.


  • Slightly off topic, but I cannot recommend enough Malcolm Harris's book Palo Alto: A History of California, Capitalism, and the World, if you're interested in tech at all. I'm almost done with the book and it's sooo good. He does an excellent job of writing a compelling narrative relating to the history of silicon valley, and to be honest it's been a real page turner despite being a dense history book.

    PDFs are hard because you need a big e-reader screen. Text only formats like Epub or Mobi are much easier. If you think you can find epubs for all the PDFs you want to read, I'd recommend getting an old Kindle. I'm partial to the Kindle Touch (which can be jailbroken easily). You can often find them for around 20 USD on eBay, which is the cheapest you can get something like this.


  • Intel laid off 1 out of every 5 people in the division I worked for about 8 months ago, myself included. I'm sure this will fix the morale problem they have!

    spoiler

    Yeah I know I shouldn't have been working there, but it was my first job out of school and they laid me off pretty soon after I realized how evil they were. At least I got some severance so they effectively paid me to quit, which I wanted to do anyways at the time


  • I'd say if tomatoes are out of season and you're cooking them anyways, like in a stew or a sauce, even bad canned tomatoes are probably better. If you have access to good fresh tomatoes, they can be better than most canned tomatoes, but like high quality canned ones are hard to beat.

    Also, the less processed the canned tomato, the better it is. If you want the best tomato flavour, get whole canned tomatoes, rather than diced or crushed.





  • Lol I was there recently and also noticed that. The whole museum was full of propaganda, but it was cool to see some of the exhibits, like the Trabant. Some "fun" anticommunist highlights included:

    • The dystopian evil jail cell run by the communist dictators (about the same size as the room I rent in [major city, imperial core country])
    • The dystopian evil kindergarten with a rigid schedule including play and nap time
    • The dystopian evil standard allocated apartment that EVERYONE had and there was NO individuality (much bigger than the room I rent, and for much less money)
    • The dystopian evil SEX that all the HORNY EAST GERMANS were having (the museum explained it as a result of there being nothing else to do, lol)
    • The dystopian evil DIY repair culture
    • The dystopian evil tired bureaucrats who looked more like people than Bond villains
    • The dystopian evil LGBTs who weren't forbidden from existing by the state
    • The factory farming that happened under the DDR (which, like, as a vegan, sure, but it's not like the Federal Republic or any Western country wasn't doing this)
    • There was literally a panel saying that all Eastern bloc states weren't allowed to deviate from the USSR's policies or will, then gave an example of the DDR doing just that to resist Soviet reforms in '85

    And every single bullet point here made my blood boil (supposed to be a translation of some of the key terms, without propaganda):

    spoiler (sorry, I only photographed the English text)

    Anyways, I guess I funded anticommunist propaganda by visiting and also buying a DDR patch


  • piccolo [any]tochatquitting caffeine?

    Here's my experience (recently diagnosed ADHD, suspect maybe AuDHD):

    Starting about 6 years ago, I started having fairly large amounts of caffeine (300-400mg/day), probably as a way of self medicating ADHD and compensating for too little sleep). At this point, I realized I was physically addicted to caffeine, and if any day went by where I didn't have caffeine by say 3pm, I'd get a bad headache. For the next ~3 years after starting this, I didn't go a single day without coffee.

    Starting about 2-3 years ago, I decided that I really didn't like the idea of having to have a coffee every day, so I decided to try to stop my addiction. I stopped abruptly and didn't have any caffeine for a month (for me, I knew a gradual stopping wouldn't work, I had to fully commit to it to get it to stick). It was miserable, especially for the first 3-4 days. The first week as a whole was pretty rough, then week 2 was marginally better, week 3 a bit better still, and week 4 felt good, finally.

    Since then, because I really like the taste of coffee, I've been consuming 2-3 coffees per week, but I try to avoid having them on consecutive days. I think it works pretty well for me, and I have managed to hold off the physical addiction like that (except for one time where I compensated for jetlag with lots of coffee, and got re-addicted and had to do the same miserable process as above).

    Also, I recently started stimulant meds for my ADHD (Vyvanse in particular), and for a while I couldn't have caffeine because it made me too anxious. Now, I'm used to the meds and can have caffeine, but it's much easier to resist the temptation.

    All in all, I'm happy that I'm not addicted anymore, and for me it was a painful process but worth it. I find that caffeine messes with my sleep even many hours after consumption, and I don't feel as rested on days when I have it. I've mostly switched to drinking tea or decaf coffee, and I think it's made me feel less anxious too.

    Let me know if you have any questions!


  • In my experience the red cups were used for mixed drinks being served by amateur bartenders (or jungle juice), or for kegs, or for drinking games. The latter was by far the most common - beer pong, slap/stack cup, etc. Often, people would rinse and reuse them to cut on waste and/or cost.
