  • I’ve got a fun one to share from my college programming professor. Similar situation, they had a machine that kept locking up, and this was back in the days of huge mainframes the size of rooms. So they call the repair tech from the manufacturer.

    So the repair tech shows up to the office gets the run down on what’s been going on, and goes out to his car and brings in a huge piece of wood and just starts wailing on the thing as hard as he could. The whole office was freaking out thinking this guy had lost it, and he later explained that the memory was a grid of magnetic coils, and the coils would rust and the rust shavings would fall between the coils below, corrupting the memory bits. So he was shaking them loose by slamming the machine with this piece of wood. Lol wild times.

  • I’ve been clinging to my 10 year old Logitech diNovo Mini, but when this thing kicks the bucket dunno how I’m gonna replace it. Trackpad has been pretty good, and I like the fact that it turns off and is protected when the clamshell is closed so I don’t accidentally press stuff when it gets lost in the couch. We really need an open source mini keyboard so people can make their own and customize buttons, etc.

  • Am I the only one that thinks that USB-C power delivery is a con?

    Having the option to charge with usb-c in a pinch is a really nice feature, but for longterm use I’d really rather usb-c plus a seperate barrel jack for power.

    The barrel jacks on business line laptops are usually a separate module that if it breaks from catching the cord with your foot and ripping it out of the laptop, you can replace the module. I’m not sure I’ve really seen replaceable usb-c power jacks very commonly, they’re usually part of the motherboard because it’s a combined power delivery/thunderbolt port or something. Now if you rip the cord out the jack is totally fucked And you have to solder a new one on.

    I don’t have a Lenovo, but a Dell Latitude that i use like a desktop, mostly plugged in next to my couch. In the bios you can set it to optimize the battery and charging for ‘primarily AC usage’, as well as set a percentage to limit charging, I think I have it set to 85%, I would assume you can do the same on a Lenovo.

    I wouldn’t worry too much about it past that, if leaving it plugged in all the time is convenient, just do that. You could also probably buy a new battery on eBay and replace it if your battery is actually shot and you want better life.



  • It didn’t get enough attention or make enough money, so Canonical dropped it. Its still on life support and slowly having some features added by the the open source community under the name ubports, but its slow going (they just updated the entire codebase from Ubuntu 16.04->18.04 and most recently 20.04) and not the best approach in my opinion, as i think every app has to be specifically developed for ubports, unlike postmarketOS where you can install anything in the repo. It also uses halium which is a translation layer for the android kernel that allows rhe Linux side to interact with hardware, since a lot of the drivers to make these phones work, aren’t mainlined.

    Also like any project like this, device support is severely lacking (especially in the US).

    Though admittedly, I didn’t realize you could get fairphone in the US now, and that it might work on us bands. So ubports on fairphone 5 might be good, dunno.
