  • IDE CD-ROM

    Yeah. I have 2, so I want to use them. The dangerous thingy is an IDE to SATA adapter. If I manage to find DVD-RW drive with front audio and a play button, I’d like to use that in an external 5.25" drive enclosure I have.
    The goal: External DVD drive that can also work as a simple standalone CD player.

    All I have now is 2 CD-RW drives like that.
    And one of them (BENQ 4816A) doesn’t seem to work with Linux for some reason.
    Sample from dmesg:

    Just keeps resetting, eventually spams a lot of errors, then goes on to start resetting again.

    VLC manages to use it for audio playback. Sort of. It can load CD info, play a track, and skip within the track. But when trying to play a different track, it again resets the drive, so it has to load the disc again, causing ~15 second gaps between tracks.

    Both digital (on PC) and analog (on drive) audio playback worked just fine on Windows 2000 after passing the USB to VirtualBox.







  • The world sucks right now for employment you might as well take a shot at a dream job because you never know what happens!

    Well, I absolutely could get training for position of train driver.
    Except…
    As far as I know, you have to agree to a contract to work for that company for at least 5 years.
    Otherwise, I’d have to pay them back for that training. How much?
    I don’t know what it’s now. First I heard from someone, they mentioned it being EUR 21,000. But recently I overheard a train driver talking to a coworker about the training costing EUR 31,000.
    Either way, in a country where the minimum wage is EUR 5.26/h… OOF.

    Although I’d have to ask for official information, as this isn’t mentioned in the advertising they do.
    But it would explain the eternal shortage they seem to have.


  • Sorry if I wasn’t clear, I am not. I am just usually imagining what happens in edge cases. Since I am in an English study programme (I honestly find English easier in relation to IT) I get the same information the foreign students do.
    And I can see how fucking shitty it is.
    The problem is they didn’t even translate the instructions to English, and further only gave them a 12 hour window until the deadline to figure things out. Ironically, the instructions highlight to really think about the decisions you make with the subjects selected (some expect prior knowledge you may not yet have). Think about it when? There’s also limited number of students to be accepted for each subject on a first-come first-served basis. Basically, a game of battle royale, but there were no instructions, and the game has already begun.










  • When talking about unemployment, I think people focus on wrong aspect. Replacing people with machines is good, that’s why we make them. The problem is with how our society functions. Rather than less work for same pay, we get unemployment as a problem.

    As for machines, I hate their weight checking. Sometimes it just needs me picking up the item and slamming it onto the bagging area. In the past, some of them used to show weight difference from expected weight, so I would be able to figure out what to shuffle around.
    There’s also issues with permissions. For example, removing items or completely exiting shopping requires employee permission. What for?
    Also, recently 2 shops decided to change the UI. In the past, you could type in number of items if you had multiple, especially useful for pastry. The new UI requires repeatedly pressing +/- buttons. Really nice when you have 15 of something.
    Lastly, scanner cooldown. They seem to have a large cooldown. I just want to quickly scan the items, but no, gotta wait 2 seconds between each item.

    The only places where it’s a bliss are supermarkets with systems like scan&shop. You take a portable scanner and scan everything as you put it into a cart, then just pay at the end in a few seconds.

    I also make my weekly backups roughly every 3 months. Which reminds me I should do it… tomorrow.

    Anyway, last time I lost some data it was when memory card I thought I had backed up died. I managed to gather most of the data from another memory card, 2 laptops, old HDD and a backup DVD as most of the files were scattered around other devices.
