  • My dad who retires today and who has been a Windows user since roughly 1993 has set up multiple Pi-Holes and OpenVPN in the last few years and recently even installed Ubuntu in WSL so he can run bash scripts locally too. He’s not in a tech job, he’s a doctor.

    A year ago my friend who has been using Windows for his gaming for the last 22 years asked my to help him set up a Fedora dual boot. Just to play around with, even though he doesn’t have a tech background. He didn’t really use it much. But today his work had him blocked by their own fuck-up and he decided to use the time to try it out again.

    This evening he told me about how he upgraded his Fedora back to a current version using GUI tools. Then he saw that Windows wasn’t the default boot in his grub boot order anymore. He tried to find an app for editing grub, realised this was the kind of thing people do with CLI. So in the next two hours he learned enough CLI using a free beginners lesson he found online somewhere, until he found the history command, where he found the grub command we used during the original setup. He was so excited about this success!

    I think the CLI criticisms are way overblown, and non-programmers can use CLIs perfectly well if they want to.


  • The original developer of Git is Linus Torvalds and he wrote it for the use of developing Linux. He handed off the project to Junio Hamano after a short while who still leads it. They use a process where you submit patches by mail, for Linux and for Git itself too.

    To make this easier they have the commands git format-patch, git send-email and git applymbox later changed to git am to apply them. They also added git request-pull to generate a short plaintext email like message to request a pull.

    The Pull Request as a bigger concept of data and discussion that should be kept around came from GitHub and was put over top of Git. The concept has been rebuilt by various competitors separately. But it doesn’t match the Linux and Git development model so they never used GitHub Pull Request, even though there is a GitHub mirror of Linux and a GitHub mirror of Git. For them the discussions happens in the mailing list.

    So it’s very unlikely they would start including the stuff that was added by others over top, that they don’t need.








  • 9 years and 4 months ago I bought an Acer laptop with a 4 core Intel Skylake with hyperthreading (i7-6700HQ) and a Nvidia GTX 960M, because the laptop I had was slow for compiling in my classes at Uni, and I wanted a discrete GPU for the occasional game when away from my Desktop PC (winter break and such (still use it for that btw)). I regretted that three times:

    • First when I wanted to install Linux instead of just using VMs. In early 2016 the kernels on live system ISOs didn’t properly support Skylake yet, so I fucked around with Arch a bunch, but didn’t end up keeping it installed. Don’t remember why, probably got busy with schoolwork.

    • Then a while later, after I had installed Ubuntu or Fedora at some point, the next issue was that cooperative mode of Bluetooth and Wifi on the included Intel wireless chip wasn’t well supported (even found an Intel Bluetooth dev saying as much on a mailing list), and it hung sometimes, so I had to make a script to turn the chip off and then rescan the PCI bus, that worked as a workaround but was still annoying.

    • Finally when we had Machine Learning classes I thought I might be able to use CUDA locally, so I tried installing the proprietary Nvidia driver and was greeted by a black screen on the next boot. Had to boot from a live system and chroot in to remove the proprietary crap again.

    On my Desktop PC I have used AMD GPUs for quite a while and dual booting Windows and Linux has always been a breeze.







  • If you divide an inequality by a negative number you have to flip the sign.

    If you want to divide out the g before knowing if it’s positive or negative you need to make the case distinction.

    If you make the case distinction and one branch results in a false statement (5 < 2 in this case), you have disproven the original inequality, or at least discovered a constraint on the original inequality. Then you arrive back at FooBarrington’s statement that includes the constraint :-)
