  • My computer has a problem where occasionally it will become completely unresponsive. (Mouse cursor doesn’t move. Keys have no apparently effect. Whatever app is running freezes. I think its a hardware problem with the graphics card, but I don’t know what. Logs at the time it freezes say “the GPU has fallen off the bus”.)

    Anyway… I recently learnt about Magic SysRq. And I’ve been able to shutdown the computer from this unresponsive state with SysRq, R E I S U O. Where as I understand it, the “E” tells processes the end nicely if they can; and then the “I” just ends them by force.

    (At this point, I’m realising that the E is SIGTERM, not SIGINT - so that screws up the relevance of my story; but I figure I’ll keep going anyway.)

    The point is, I’ve been using key combo with a nice pause between each key, thinking there was some chance that processes might be ending gracefully. But when I tried it while the computer wasn’t frozen, the computer was able to inform me that the E and I commands were disabled. (I don’t know why.) So even though I wanted to give a nice “please end” signal, in the end that just wasn’t happening.



  • Anti-cheat software is very clearly and explicitly spyware. That’s the entire purpose of it. It spies on how you use your software in the hope that if you cheat you’ll be seen by the spyware watching you.

    This spyware is generally not something people want on their computer - as evidenced by people complaining about it. So effectively whats happening is that people are being spied on against their wishes. Spyware is a common category of malware.

    So I think it’s pretty easy to see why people might describe anti-cheat software as malware.




  • Using full names like that might be fine for explaining a physical rule, or stating the final result of some calculation - but it certainly would be cumbersome and difficult for actually carrying out the calculations. In many cases we already fill pages with algebra showing how things can be related and rearranged to arrive at new results. That kind of work would be intractable with full word names for the variables, partially because you’d be constantly spilling off the end of the page trying to write the steps; but also because having all that stuff would actually obfuscate what you are trying to do - which is algebra. And during that process, the meanings and values of the pronumerals is not as important has how they interact with each other. So the names are just a distraction.

    For setting up an equation, and for stating the final result, the meanings of the variables are very important; but during the process of manipulating the equations to get the result you want the meanings of the letters are often ignored. You only need to know that it is something that can be multiplied, or inverted, or subtracted, or whatever. Eg. suppose I want to rearrange to get the velocity. I don’t care that I’m dividing both sides by the air density times the drag coefficient and the area… I’m just dividing ρCA, which is an algebraic blob whose interpretation can be saved for some other time.





  • Hey, no one is trying to stop you from doing that. I’m sure it is very convenient for you.

    My point of view though is that automatically uploading my personal files to some corporation computer on the other side of the world should not be the default when I try to save something. Maybe sometimes I’ll want to use that feature, but there are a variety of reasons why I don’t want it most of the time. And I definitely don’t like having to jump through hoops just to avoid it.


  • Forced accounts are evil - including Android. Here’s my Android story:

    When I got my first Android phone, my intention was to not have an account - or at least have as much isolation between any account and my actual usage as possible. So I decline account creation when I first started using the phone, and told the phone to only store all contacts locally. That worked, and I was pretty happy with it. But later, I wanted to download a couple of basic apps from the app store - and that required an account. So I created a bogus account to download the apps. …

    After creating the account to download stuff, I noticed that the contacts had automatically associated themselves with that new account had automatically uploaded all my contacts and personal info to google to sync with this account. This is precisely the thing I was trying to avoid in the first place. So, I immediately logged into that account via google’s website and told it to not store any contact info, and to delete all existing info. Which it did.

    But then some time later… the account again decided to sync with my phone - this time to delete all the contacts from my phone (presumably because I’d deleted them from the online account). So although I’d gone to some deliberate lengths to tell my phone to only store data locally and to not upload it, what i ended up with was all personal data uploaded, and then purged from my phone. I had to try to restore my contacts from an ancient sim-card backup from my old phone.

    Since then, I’ve decided that I will not use a google account for my phone for any reason, ever. I’ve use F-droid and the Aurora store instead. (But actually I very rarely use any apps anyway.)
