  • Filtering incoming spam, while not 100% correct, is a pretty straightforward thing to do. Use DNSBL and other lists from spamhaus and it takes care of 90+% of the problem. Incoming spam has not been a huge issue for me, but when people try to send mail to someone in M365 cloud or to Gsuite and they just decide that your server isn’t important enough they just block you out and that’s it. Trying to circumvent that takes a ton of time and effort and while it can be done it’s a huge pain in the rear. And trying to fight your way trough the 1st tier support to someone who actually understands the problem and attempts to fix that while you customers are complaining that “problem with email” is actually affecting on their income is the part I’ll happily leave behind.

    I’ll set up a couple of new VPS servers to host my personal and friends emails, but if they complain that the service I’m paying from my personal pocket isn’t what they’re after then they’re free to switch into whatever they like. And as infrastructure for that is something like 100€/year I’ll happily pay it by myself so that no one has an option to say ‘I paid for this so you need to fix it’ anymore. On commercial case that’s obviously not an option and I’ve had my share of running a business in a very hostile environment.


  • Also if you’re running an email server for others, it takes very little from single individual, like a small webshop newsletter, which enough people manually marks as junk and you’re on a block list again. Latest one with microsoft took several days to clear, even if all of their tools and 1st tier support claimed that my IP isn’t on a black list.

    I’ve jumped all the hoops and done everything by the book, but that still doesn’t mean that any of the big players won’t just screw you up because some of their automaton happens to decide so. That’s why I’m shutting my small ISP business down, there’s no more money to make on that and a ton of customers have moved to the cloud anyways, mostly to microsoft due to their office-suite pricing. It was kind of fun while it lasted, but that ship has sailed.



  • 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!




  • Is French just the most commonly spoken common language, even in Germany and Czechia?

    Not at the slightest. I suppose it’s just a marketing thing where french sounding names are supposed to be more appealing or tell something about the food or atmosphere at the hotel. And based on a very quick visit at booking.com I don’t see any french sounding hotels at Berlin, so I don’t know how many there actually are. I’m sure there’s some around like everywhere in the world, but I think majority is something else.

    And there’s a lot of shared history between countries, so that can mix things up in various ways.




  • But the end goal would be to only use that to build the network, connecting modes together through $VARIOUS_MEANS, and implement the Yggdrasil code right at the network card level.

    So, eventually it might be a (new) internet with encryption (and blackjack+hookers?). I already can connect my house trough neighbours connection (with limitations like NAT of course), but once ipv6 is available everywhere I don’t immediately see if Yggdrasil offers anything else than protocol level encryption. Current internet is a mesh network after all, just built a bit differently and more controlled manner.

    Interesting concept anyways, maybe it’ll catch up some day.


  • In short: No.

    Assuming that I understood correctly with a quick reading that’s creating a whole another network on top of existing internet and requires raw bandwidth to function at all.

    Various mesh-networks have been around for quite a long time to solve the ‘last mile’ issue on poor areas. That requires pretty dense population to actually work, but at least couple of years ago there’s been some moderately successful projects. I haven’t followed those in years, so I don’t know what’s the current status and that’s very different from what Yggdrasil is doing.
