What is the most private phone?
  • I didn't watch the video but I don't think there is any phone that lets you avoid having your location tracked. If there is wifi near where you want to use the phone, you could run a voip client on on a wifi-only tablet, perhaps.

    I've been wondering whether satellite communications gizmos with no GPS allow any type of precise location tracking from the satellite. I've been interested in this, which lets you exchange text messages at fairly low cost (about 2 cents per 50 byte unit). Besides possible privacy advantages, it also lets you communicate where there is cell coverage:

  • 2FA Apps for Linux Desktop?
  • What exactly do you want it to do? You can implement TOTP with a 10 line python script and I probably have a few of those kicking around. I've ended up doing that at least a couple of times.

  • Graphene vs LineageOS what's the diff?

    People keep mentioning GraphineOS as a reason to buy a Pixel, but in other regards the Pixel hardware doesn't seem so great. If you get a different phone that can run Lineage, is Graphene really better? Thanks.

    Experiences self-hosting an IRC bouncer?
  • I set up ZNC and got it working but it was a pain in the neck, took some trial and error, and the docs were confusing. Once I got it going I basically left it alone rather than try to clean up the situation.

  • What other kinds of things can period-tracker apps be used for?
  • Don't, just don't, or maybe do. A lot of those apps phone home with your period info to help marketers and the secret police infer when you might be pregnant. So if you're going to use such an app at all, use it for anything except actual period tracking. That should at least confuse them.

  • What was a time that two adversaries had such different objectives that they were practically playing a different game against each other?
  • In chess there is a fairly common situation where you are in first place in the last round of a tournament, 1/2 of a point ahead of your opponent (you get 1 point for winning a game and 1/2 point for a draw). So if you win or draw the game, you win the tournament and get a lot of money. If you lose the game, your opponent wins the tournament and gets the money. You get 2nd place, i.e. less money possibly split with other competitors.

    That means you can choose a safe playing strategy that likely leads to a draw, while your opponent has to choose a risky strategy with higher chances of winning.

    (Some chess context: high level games are usually drawn. They are only won by someone making a mistake. Also, the first move (white pieces) confers an advantage, so it's usual to seek winning opportunities if you have white, while just trying to hold the draw if you have black. To attempt winning with black requires seriously risky play. Bobby Fischer basically conquered chess in the 1960's by constantly trying to do that, which required playing with maniacal intensity all the time).

  • What was a time that two adversaries had such different objectives that they were practically playing a different game against each other?
  • US presidential election last week. Republicans wanted first and foremost to win it, and secondly to implement awful policies in the event that they won. Democrats wanted first and foremost to implement bad (maybe not 100% awful) policies, and were willing to seriously risk losing (and in fact lost) in order to avoid running on a popular platform. They did the same on many prior occasions too.

  • What resources do you recommend for an adult wishing to relearn math?
  • I'd expect textbooks would have tons of exercises at that level. Schaum's outlines are good for college level math but I don't know if they have them for stuff like basic algebra. I have a friend who is a HS math teacher so I can ask her for recommendations and get back in a day or so, hmm.

  • What resources do you recommend for an adult wishing to relearn math?
  • You have to write out a lot of exercises and there is no getting around it. You can't learn the violin by watching videos or reading a book. You have to practice. It's the same with math. But as people said, Khan Academy lectures are very good in steering you through a topic.

    Besides algebra, I think it is important to know a bit about probability and a bit about logic. Don't worry about stuff like covariance matrices, but understand what conditional probability is (be able to explain the "prosecutor's fallacy") and write out some of those annoying exercises about urns full of colored balls. Also, show how to write e.g. "you can fool all of the people some of the time, and some of the people all of the time, but you can't fool all of the people all of the time" in predicate logic notation, and see how the parts of the sentence involve switching the order of quantifiers.

    phys.org News consumers are more influenced by political alignment than by truth, study shows

    For many years, the conventional wisdom was that only highly biased, less educated media consumers would put partisanship over truth—in other words, they would believe news that confirmed their worldview, regardless of whether it was true.

    Many voters are willing to accept misinformation from political leaders – even when they know it’s factually inaccurate, if they believe the statements evoke a deeper, more important “truth.”
    theconversation.com Voters’ ‘moral flexibility’ helps them defend politicians’ misinformation − if they believe the inaccurate info speaks to a larger truth

    In a series of surveys, researchers studied when and why voters put up with inaccurate statements from their leaders.

    Voters’ ‘moral flexibility’ helps them defend politicians’ misinformation − if they believe the inaccurate info speaks to a larger truth

    Many voters are willing to accept misinformation from political leaders – even when they know it’s factually inaccurate. According to our research, voters often recognize when their parties’ claims are not based on objective evidence. Yet they still respond positively, if they believe these inaccurate statements evoke a deeper, more important “truth.”

    Does anyone here use GNU Jami?

    Is it ok? Is there something else you recommend instead? I tried nextcloud talk and it was pretty bad. Jitsi was ok but self hosting it looked complicated. FOSS only, of course.

    Is Telegram really an encrypted messaging app?

    Blog post by crypto professor Matthew Green, discussing what Telegram does (I wasn't familiar with it) and criticizing its cryptography. He says Telegram by default is not end-to-end encrypted. It does have an end-to-end "secret chat" feature, but it's a nuisance to activate and only works for two-person chats (not groups) where both people are online when the chat starts.

    It still isn't clear to me why Telegram's founder was arrested. Green expresses some concern over that but doesn't give any details that weren't in the headlines.

    Pi Pico 2 Extreme Teardown

    This is a good blog post, with die photos of the new RP2350 chip and a brief description of what they show. There is a link to a 12 minute youtube video that is also very good, that discusses the die shots in more detail and also goes over the rest of the Pico 2 circuit board, including die shots of the QSPI flash chip and the voltage regulator chip.

    Raspberry Pi Pico 2, our new $5 microcontroller board, on sale now

    Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.

    Google Fiber is the only decent home ISP around here. What do I do?

    I get spammed by them all the time but have so far resisted and stayed with my crappy, slow, and expensive ADSL provider out of principle. But the ADSL provider just raised prices on me AGAIN and it's ridiculous.

    What do I do? Is Google Fiber as invasive as other Google stuff? What if I just use it to tunnel a VPN to a non-Google endpoint?

    This is sure annoying. It occurs to me that Comcrap might be available here as an alternative, but that must be as evil as Google. At least the ADSL company is reasonable about privacy, as such companies go.

    Thanks for any thoughts.

    Lemmy (etc.): allow sorting preference for search

    It's a pain that search results on lemmy show by default ordered by some useless relevance ranking. I can't think of a single time I didn't want newest first. I couldn't find a preference to request that. It would be great if there was one.

    The suggestion on c/support on lemmy.world was to make this kind of request on github, but it seems anti-FOSS to me to require a Microsoft account for a fediverse request, so I'm posting here and hoping for the best.

    Thanks for any consideration!

    automatically clean up tracking and other tags in posted urls

    Example (spam post containing an amazon affiliate link, post hopefully deleted by now but I assume mods/admins can see it): https://lemmy.world/post/15846936

    Also there are tons of links people post legitimately but have tracking parameters, gclid=this, fbclid=that, etc. Those can be cleaned up too.

    By editing out these parameters automatically when the link is posted, people's privacy can be protected and the incentive to post affiliate spam can be decreased.

    It could be a server config parameter and/or put into the posting UI: "your post contains [link] with flagged parameters, choose between a) post cleaned up version (shown), or b) post link without changes (may go into moderation queue depending on community settings)."

    f-droid just requested permission to update other apps?

    Any idea why? I've been using it for months. I probably had to grant permission when I first installed it, but haven't had to again since then, until just now.

    Also, some of the time, when F-droid updates an app, the update just goes through. But other times I get a dialogue asking "do you want to update this app?". It seems random. Any idea?

    Phone is a Moto G5 Stylus 2023 and it recently got a security update from Motorola, but I think I've done some F-droid updates since then. However, this may be related.

    The other possibility is that something might have happened to F-droid's code signing credentials, e.g. someone messed with them? That thought is basically why I'm asking here.
