    Lossless compression algorithms aren’t magical, they can’t make everything smaller (otherwise it would be possible to have two different bits of input data that compress to the same output). So they all make some data bigger and some data smaller, the trick is that the stuff they make smaller happens to match common patterns. Given truly random data, basically every lossless compression algorithm will make the data larger.

    A good encryption algorithm will output data that’s effectively indistinguishable from randomness. It’s not the only consideration, but often the more random the output looks, the better the algorithm.

    Put those two facts together and it’s pretty easy to see why you should compress first then encrypt.



  • They collect:

    The categories of websites you visit, but not the URL itself

    The information collected includes categorized web browsing history that shows how long and how often you visited specific categories of sites (i.e. social media, personal finance, or news). All site visits are classified into one of 30 categories. We do not collect URLs, web pages titles, or user-specific content without explicit permission from you.

    Software usage: for example, frequency and duration of application usage such as Intel® Driver & Support Assistant, but not the application content itself such as specific actions or keyboard input.

    Feature usage: for example, how much RAM you usually use or your laptop’s average battery life.

    Other devices in your computing environment

    Includes universal plug and play devices and devices that broadcast information to your computer on a local area network: for example, smart TV model and vendor information, and video streaming devices.

    (the emphasis is mine, as is the minor reordering to not hide the browsing behaviour stuff at the bottom)

    Yeah that’ll be a no from me there, bud.

    I wrote about this elsewhere. Every post about Reddit or place has tons of comments like yours insisting that any engagement is good for Reddit. I disagree.

    Reddit want dissenting users to leave! They have no interest in retaining it’s traditional userbase of cynical, lefty, tech-savvy users. They’re incredibly intolerant of advertising and difficult to monetise, and much of the reason why Reddit hasn’t made as much money as some of its competition.

    They’d rather we all went elsewhere and left them with doomscrollng cryptobro memelords that don’t care if a post is a corporate shill or not, as long as it’s entertaining.

    Sure, not engaging with their site reduced their numbers and thus value. But the number of users on Lemmy is a tiny fraction that I guarantee they’d be happy to lose if it made their userbase more tolerant of corporate bullshittery.

    My goal isn’t to knock a fraction off their IPO valuation, it’s to bring other users and communities over to better platforms like this one. Or, perhaps, for Reddit to realise they done fucked up and roll back some of those user-hostile changes. That takes advocacy and reminding people of the failings of the platform’s admins.

    This form of protest is valid and I support it.






  • we’re seen as evil because we’re helping DRM exist and we’re ensuring people make money out of games

    No, you’re seen as evil because your software is an inefficient and invasive security risk that makes games significantly worse, and compromises/punishes your paying customers in the quest for more money.

    I no longer pirate games (thanks to Steam), but I’ll never buy one with Denuvo.

    Fuck allllll the way off.
