  • It lags for me whenever I access some filesystem that takes a while to respond. That could be a faulty or old device, or it could be an NFS share with multiple large file transfers going on in the background.

    And when I say it lags, I don’t mean it just takes a while to show me a directory’s content, I mean the entire UI freezes and kwin will grey out the window because tha application isn’t responding any more.

    This does not happen a lot, and if your file browsing is largely limited to a fast local storage, like a SATA SSD or even an NVMe, you may well never see this problem at all. But it does happen.



  • Okay, I’m generally on the side if dolphin UI-wise, but when it comes to the topic of lagginess, it has to be said that dolphin, and in fact, almost everything using the kio infrastructure, is the one shitting the bed here. You’d think a bit of multithreading will keep the UI from freezing up whenever the underlying I/O has some minor hiccup (which can absolutely happen in practice with network filesystems or USB sticks in combination with large file transfers), but apparently dolphin can’t do that.







  • The reason I gave up self hosting email was because all my emails kept going to spam for everyone I emailed.

    You need to set up DKIM, SPF and DANE, then most big email providers will accept your mail. Worst case, you may need to contact them to unblock your mail server’s IP if that has been used by a spammer prior to you.

    Plus incoming email needs spam protection.

    Both SpamAssassin and Rspamd do a decent job of that.

    Note: I’m using rspamd, and for some time at the beginning, it looked like it wasn’t really doing anything. Turns out it needs a couple hundred training emails before it will start using the Bayes function. Just feed your Spam folder into the learn_spam command and any of your normal, not-spam folders into the learn_ham command.


  • Domain registration information can usually be found out somehow, although these days you have to jump through some additional hoops to get it, and those hoops are designed to discourage automated lookups. The privacy gains you get from hosting your own email server, though, are massive and IMHO more than worth it. If you are not hosting your own mail server, then the most you can expect from having your own domain is nicer looking email addresses. Depending on what your hosting provider supports you might also get unlimited aliases, maybe even regex aliases, which can be very helpful when handing out mail addresses to various companies and internet services.

    If your main concern is that your email address should not be associated with your real identity, your best bet is to just use a VPN to connect to any large email hoster, like ProtonMail. (Obviously don’t use Proton Mail if Proton is also your VPN.)

    This is x86 assembler. (Actually, looking at the register names, it’s probably x86_64. On old school x86, they were named something like al, ah (8 bit), ax (16 bit), or eax (32 bit).) Back in the old days, when you pressed a key on the keyboard, the keyboard controller would generate a hardware interrupt, which, unless masked, would immediately make the CPU jump to a registered interrupt handler, interrupting whatever else it was doing at the point. That interrupt handler would then usually save all registers on the stack, communicate with the keyboard controller to figure out what exactly happened, react to that, restore the old registers again and then jump back to where the CPU was before.

    In modern times, USB keyboards are periodically actively polled instead.

    Germany’s Angela Merkel called the U.S. president’s words “sobering and a little depressing"

    Meanwhile, the Italians thought he was too chaotic and disorganized, the Greek didn’t like his lack of work ethic, the French objected to his constant philandering and the British were put off by his taste in food.
