  • True words. The sustained effort to keep something in decent shape over years is not to be underestimated. Now when life changes and one is not able or willing anymore to invest that amount of time, ill-timed issues can become quite the burden. At one point I decided to cut down on that by doing a better founded setup, that does backup with easy rollback automatically, and updates semi-automatically. I rely on my server(s), and all from having this idea to having it decently implemented took me a number of months. Just because time for such activities is limited, and getting a complex and intertwined system like this reliably and fault tolerant automated and monitored is simply something else than spinning up a one off service


  • And they believe all employees actually remember so many wildly different and long passwords, and change them regularly to wildly different ones? All this leads to is a single password that barely makes it over the minimum requirements, and a suffix for the stage (like 1 for boot, 2 for bitlocker etc), and then another suffix for the month they changed it. All of that then on sticky notes on the screen.




  • How does this part (which is what the headline refers to and presumably the most outrageous inspection finding)

    At one point during the examination, the air-safety agency observed mechanics at Spirit using a hotel key card to check a door seal […]. In another instance, the F.A.A. saw Spirit mechanics apply liquid Dawn soap to a door seal “as lubricant in the fit-up process,” according to the document. The door seal was then cleaned with a wet cheesecloth

    have anything to do with the opening of the article

    Just last week, a wheel came loose and smashed through a car, and earlier this year the door from a 737 Max aircraft broke off mid-flight

    ???

    The article misses the whole point, which is that the audit did not uncover the sources of these incidents.

    Those are symptoms of sitting at that operation point permanently, and they are a of course a concern. What I’m after is that people think that energy gets put in to the battery, i.e. it gets charged, as long as a “charger” is connected to the device (hence terms like “overcharged”). But that is not true, because what is commonly referred to as “charger” is no charger. It is just a power supply and has literally zero say in if, how and when the battery gets charged. It only gets charged if the charge controller in the device decides to do that now, and if the protection circuit allows it. And that is designed to only happen if the battery is not full. When it is full, nothing more happens, no currents flow in+out of the battery anymore. There’s no damage due to being charged all the time, because no device keeps on pumping energy into the cell if it is full.

    There is however damage from sitting (!) at 100% charge with medium to high heat. That happens indipendently from a power supply being connected to the device or not. You can just as well damage your cells by charging them to 100% and storing them in a warm place while topping them of once in a while. This is why you want to have them at lower room temperature and at ~60%, no matter if a device/“charger” is connected or not.

    (Of course keeping a battery at 60% all the time defeats the purpose of the battery. So just try to keep it cool, charged to >20% and <80% most of the time, and you’re fine)


  • “overcharging” doesn’t exist. There are two circuits preventing the battery from being charged beyond 100%: the usual battery controller, and normally another protection circuit in the battery cell. Sitting at 100% and being warm all the time is enough for a significant hit on the cell’s longetivity though. An easy measure that is possible on many laptops (like thinkpads) is to set a threshold where to stop charging at. Ideal for longetivity is around 60%. Also ensure good cooling.

    Sorry for being pedantic, but as an electricial engineer it annoys me that there’s more wrong information about li-po/-ion batteries, chargers and even usb wall warts and usb power delivery than there’s correct information.


  • It is not that easy to understand what you want, to me it reads like you want something like Nextcloud - i.e. your own little cloud, where you can put all your stuff, and view it through the webbrowser or the nextcloud apps, and also keep selected parts of your stuff in sync with your devices (or automatically upload photos take with your smartphone for example).

    Backup of Nextcloud (or whatever you want to use) is a seperate topic. Any incremental backup tool would apply though, so there’s much to choose from. I personally use btrbk which uses Btrfs Send+Receive to push incremental snapshots to an offsite server.



  • It is not a fork aiming to replace it. It is rather a spin with saner defaults to cater to companies as customers. The product which shall carry ondsel financially is their freecad compatible cloud offering, and the hope is to use that for elevating freecad itself too. They need their spin to be able to ship an ootb experience fitting their motive and brand. So if you would like a less confusing experience it might be something for you. Currently there’s a lot of borderline deprecated and also redundant functionality in freecad, so I hope that ondsel’s cleanup mantra will make it to the ootp upstream experience as well.



  • This covers just the basic cpu instructions, no proprietary extensions, no architecture of additional necessities like a gpu, no proprietary firmare for the gpu or anything else. The instruction set of Arm, x86 or whatever is not a secret though. The freedoms in risc-v are mostly concerning the manufacturers, which can build chips using this instruction set without paying any royalties. From a consumer point of view, that at most means one can at most choose from a more organically grown landscape of risc-v chips. Which in turn bears the risk of ending up in a situation, where all we have is a vast jingle of cluttered proprietary extensions, that make it harder to write libre drivers for than it is for Arm today.

    Don’t get me wrong, risc-v is absolutely amazing! But in terms of freedomness, it would take a manufacturer to extend the spirit of open hardware to the complete SOC - and the basic instruction set is pretty much the smallest piece in that.


  • Yes. But the more advanced LLMs get, the less it matters in my opinion. I mean of you have two boxes, one of which is actually intelligent and the other is “just” a very advanced parrot - it doesn’t matter, given they produce the same output. I’m sure that already LLMs can surpass some humans, at least at certain disciplines. In a couple years the difference of a parrot-box and something actually intelligent will only merely show at the very fringes of massively complicated tasks. And that is way beyond the capability threshold that allows to do nasty stuff with it, to shed a dystopian light on it.

    Yes, if it was as object based as it claims, Get-WmiObject would subtract WmiObject from Get. Instead it is like having all the clutchy drawbacks from being object based without reaping any of the potential bemefits.

    If you want anything that actually is object based, just use xon.sh - sane and familiar syntax with insane amounts of power just like that
