  • My bank uses 6 digit ‘customer number’ (which is set by the bank) and that’s verified with an app and a personal PIN (app shows ‘login attempt ABCD at mm.dd. hh:mm’ where ABCD is shown on login page too) or via SMS OTP (again with ‘ABCD’ verification). And again with personal pin + app or OTP to confirm transactions. The app itself can be protected with a fingerprint or phone pin and every new installation needs to be registered to the system, so I can’t just use my phone app to access my wifes account (or anyone elses) but I still can map multiple accounts (like corporate ones) to the same installation.

    I think that’s pretty reasonable approach.


  • The command in question recursively changes file ownership to account “user” and group “user” for every file and folder in the system. With linux, where many processes are run as root and on various other accounts (like apache or www-data for web server, mysql for MySql database and so on) and after that command none of the services can access the files they need to function. And as the whole system is broken on a very fundamental level changing everything back would be a huge pain in the rear.

    On this ubuntu system I’m using right now I have 53 separate user accounts for various things. Some are obsolete and not in use, but majority are used for something and 15 of them are in active use for different services. Different systems have a bit different numbers, but you’d basically need to track down all the millions of files on your computer and fix each of their permission by hand. It can be done, and if you have similar system to copy privileges from you could write a script to fix most of the things, but in vast majority of cases it’s easier to just wipe the drive and reinstall.



  • I’m pretty sure the cameras around here don’t use OCR at all or even if it does it only recognizes the format for plates from a thing shaped like a plate. So if you’re driving like an ass with the drop tables-“plate” that is pretty relevant.

    The Bobby Tables one I’m quite sure would work at least on some systems if they let you input your kids name by yourself to some sort of digital form. Or at least I would be pretty surprised if every school system on earth would be patched against simple sql injections.

    Bing Chat (so ChatGPT) wrote an opening scene (or maybe more like a trailer, prompt was opening scene) too:

    The opening scene of “Server Down” begins with a shot of a high-tech skyscraper. The camera then zooms into the basement of the building, where we see Jack Bauer, a nerdy and obsessive system administrator, working on his servers. He is surrounded by racks of blinking machines, tangled cables, and humming fans. Jack is wearing a t-shirt with a witty tech joke printed on it, and he is sipping a cup of coffee from a “World’s Best Sysadmin” mug.

    Suddenly, the lights flicker, and the servers go offline. Jack’s face turns pale, and he drops his coffee mug. He frantically tries to reboot the servers, but nothing works. He checks the network connections, the power supply, and the cooling system, but everything seems fine. He then realizes that the problem is not with his servers, but with the building’s infrastructure. He rushes to the security room, where he finds out that the building has been taken over by terrorists.

    The camera then cuts to the terrorists, who are holding the employees hostage and demanding a ransom from the government. They have cut off all communication lines, disabled the security cameras, and planted a bomb in the building. They are confident that they can get away with their plan, but they didn’t count on one thing: Jack Bauer.

    The scene ends with Jack staring at the security monitors, his eyes burning with determination. He knows that he has to act fast to save his servers, his colleagues, and himself. He takes a deep breath, puts on his backpack, and heads towards the ventilation ducts. The adventure begins!


  • Bare feet are a bit clickbaity on the headline. That alone doesn’t mean much, but when it happens on a area where you should have full protective gear at the (supposed to be) sterile part of the manufacturing it’s of course a big deal. But it would be equally big deal if you just stroll there in your jeans and t-shirt with boots you stepped on a dog shit on your way to work. And even then it’s not even close of being the biggest issue on manufacturing where they constantly ignored all of the safety protocols, including ignoring test results which told them that the product is faulty.
