  • I think what just_another_person means that Lenovo, specially at the beginning when they got the Think-brand from IBM years ago, tried to ride the brand and released sub-par laptops under ThinkPad -brand. At least some of the L-series were closer to what you could get from your local supermarket than actual work machines.

    The brand-riding is now greatly less and the crappy ones generally aren’t the models you can find refurbished from 3rd party retailer. I’m currently using T495 and it was ~300€ from a sale couple years ago, now you apparently can get L13 for less than that. And of course, when you buy used units do your homework and only make deal with a reputable seller, there’s always an option that previous owner didn’t treat the thing nicely.



  • The best mechanics can track down an issue by reasoning about what could be causing it

    Same principle works with IT. I do and have done sysadmin stuff for quite a while and there’s always some random software or whatever I’ve never heard of and someone comes and asks me to fix it. Then you start to ask questions, “what exactly doesn’t work”, “can you show me what you’re doing”, “what should happen when you press that button”, “can you show settings on that thing” and so on. Then you can start to dig down, does the server they’re using respond to ping, does DNS resolve (it’s always DNS after all), does that thing work on the next workstation, when did the problem appear and was there some other maintenance or changes going on at that time and so on.

    Same principle, just start to reason the whole thing from bottom up, check everything you come across untill you find something which doesn’t work and then do what’s needed to fix that, rinse and repeat until the problem goes away and make sure that what you’re doing won’t cause new problems. Just the tools are different, the mindset is more or less the same.


  • Does a senior mechanic need to understand the physics of piston design to be a great mechanic

    I would argue that if senior mechanic doesn’t understand the physics of piston design at least on some degree he’s not a great mechanic. Obviously mechanic doesn’t need understanding on metallurgy, CAD models and a ton of other deeper level stuff just like an IT engineer doesn’t need to know on a deep level how circuit boards are designed or how CPU die manufacturing process works. But both benefit greatly when they understand why something is built the way it is.

    I’m also an systems engineer of sorts and have worked with software engineers. And I’ve had requests like “Can’t you just set 'bind-address = 0.0.0.0 on mysql-server and disable firewall” on a directly internet-facing machine and then received complaints when I’m “making things more difficult” from “senior software” -titles. Sure, I can’t write the code they’re doing, or at least it would take me a crapload of more time to do that but on the other hand there’s guys who have so very narrow understanding on anything they work with that it makes me wonder how they can do their work at all in the first place.

    Of course no one can master everything in any field but I find it concerning that a lot of guys just press the buttons more or less randomly until their thing works without any clue on what they actually did and how it might affect on different parts of the house of cards they’re building.




  • “But don’t forget the situation we are in. Now is the time of military censorship, unprecedented for our country. After all, the war is going on in the information space too,” Peskov is quoted as saying by the magazine.

    So it is a war after all? And that front goes both ways, you can see even here on Lemmy comments which could be paid actors on behalf of Russia. Most likely not all of them get paid, but I’m pretty sure at least some do (obviously not focusing just on Lemmy).


  • As long as there’s no military need for them against an invasion there will be zero mines in the ground. No one will hurt themselves with them, unless some storage worker happens to drop a box on their toes.

    As of why now, you can’t pull out of agreement and start to build up manufacturing and logistics if there’s active invasion going on. I hope not a single one of them is ever dug on our Finnish soil, but I’m glad that our military is prepared to use any viable option if they need to.


  • Are all the distros having the same GNU/Linux kernel

    Yes. Different distros have different versions, patches and so on, but the underlying kernel is the same.

    if I replace all the Arch userland files into Debian’s, the system will become Debian?

    If by “userland” you mean files which your normal non-root user can touch, then no. There’s differences on how distributions build directory trees, file locations, binaries, versions and so on. You can of course replace all the files on the system and change distribution that way, a convenient way to do that is to use distros installer but technically speaking you can also replace them manually by hand (which I don’t recommend).



  • a) that doesn’t really sound like the fault of EVs or the charging stations themselves. Any sort of very moderate air current would cause the same problem.

    Excactly. The stations themselves don’t create particles but magnetic fields from the high voltage DC lines and cooling fans just pick them up from the ground and back to air. It’s quite misleading to claim this is “Fine particulate matter emissions from electric vehicle fast charging stations” as the stations just redistribute existing emissions.

    Obviously this is not a good thing, but the underlying cause is something else than these stations, I’d bet considerable amount of it comes from combustion engines. And as you said, simple filters should fix the problem and clean up the pollution from environment as well.
