  • I looked into it a while ago but I gave up on the idea after realizing how few programs can actually run on one. There’s no “reverse VM” software that allows you to seamlessly combine multiple physical machines into one virtual one. Each application has to be specifically designed to take advantage of running on a cluster. If you’re writing your own code, or if you have a specific project in mind that you know supports cluster computing then by all means go for it, but if you’re imagining that you’d build one and use it for gaming or video editing or some other resource intensive desktop application, unfortunately it doesn’t work like that.

    Edit: I dug up a link to the post I made about it in /c/linux. There’s some good discussion in there if you’d like to learn more https://lemmy.world/post/11528823


  • Check how nearby colleges and universities dispose of used assets. The state school near me maintains a very nice website where they auction off everything from lab equipment to office furniture. It’s also where all their PCs go when they hit ~5 years old and come up in the IT department’s refresh cycle. Only problem in my case is that they tend to auction stuff in bulk. You can get a solid machine for $50 to $100, but only if you’re willing to pay $500 to $1000 for a pallet of 10.


  • TBH I just use the Feeder app on my phone. Fully self-contained. No account, no server, no middleman of any kind. Just the app.

    I’ve been meaning to set up something more elaborate, but this really does work fine, and I like to mention it in these threads for anyone who’s interested in RSS but thinks it’s a big lift to set up. It can be complicated, but it doesn’t have to be. Download an app and start adding publications that interest you. That’s all it takes to get started.





  • Alright, I’ll take the bait. Let’s do some recreational math

    This web page contains average passenger car fuel efficiency broken down by year. The most recent year available is 2016, so we’ll use that: 9.4 km/L or 22.1 miles per gallon. A gallon of gas has about 120MJ of energy in it. So, an average car requires about 120,000,000 / (1/22.1) = 5.4MJ per mile

    This web page has calories burned for different types of exercise. I separately searched and found that the average adult in the US weighs around 200LBS, so we’ll use the 205LBS data, and I’m going to assume that “cycling - 10-11.9 MPH” is representative of the average commuter who isn’t in too much of a hurry. That gives us 558 calories per hour, or 55.8 calories per mile (using the low end of the 10 to 11.9mph range). That’s equal to about 0.23MJ per mile (as an aside, it’s important to note that the calories commonly used when talking about diet and exercise, are actual kilocalories equal to 1000 of the SI calories you learned about in school.)

    Moral of the story: an average bike ride consumes around 20x less energy than an average drive of the same distance.








  • Huh, I was under the impression that they used their own index. I just did a quick search found a blog post they publisted back in 2023. Here are some relevant excerpts:

    At the time of publication, Qwant has in its servers 20 billion indexed web pages

    Qwant uses Bing to supplement search results on which we do not have sufficient relevance, and on images where storage capacities are very important. On the rest, the main SEO logics are often the same which explains why you often find the same search results, ranked slightly differently according to the weight given to one or the other.

    Of course, that’s the company pushing their own preferred narrative, so take it with a grain of salt. But assuming it’s not an outright lie, then they’re definitely more independent than a lot of other search engines.
