  • 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.






  • In our local craigslist for cars website someone has been selling a -84(or so) Nissan Sunny for ages with electric conversion. The seller did just that, took combustion engine out, attached a electric motor into transmission and the result is that you have 80’s car, with manual transmission and batteries so small that once you’re out of the driveway you’ve depleted 10% of the batteries (give or take, but that’s pretty much what you’ll get). And it had something like 15kW minus losses of the drive train.

    But the parts are so expensive (at least for now) that listed price is almost 10k€. I can understand that seller wants their money back and it isn’t the most serious conversion out there, but the reality is that you’ll get a shitty 80’s car with a even shittier EV conversion (since the frame has it’s limits and high quality components are expensive) while you can sell a similar car with a combustion engine for 350€ on a good day and a tank full.


  • Power train conversion is reasonably simple. Just throw combustion engine and transmission box away, make brackets for electric motors and attach them directly to the wheels (with axles if necessary). Conversion of controls is (I assume) is also somewhat simple since existing brake system and power steering is quite straightforward to run with electric motors since you just need something which can run a belt drive and gas pedal is most likely already electric. For all the electronics you have plenty of space in where the engine used to be.

    But. And there’s a pretty big but. Batteries are pretty big and pretty heavy. On any given combustion engine car there’s just no room for them (at least if you’re after a conversion with similar range/power than a readily built electric car). And even if you cut the floor panel off and modify it to accomodate battery pack (or whatever the route you choose might be) it’ll heavily affect weight distribution, frame stability and many other things, suspension included. Model S battery is apparently 540kg, so if you’ll do a conversion to your corolla you might save around 150kg of weight by removing old engine+transmission but you’d still have additional 300kg of mass to deal with.

    For a van which is designed to haul heavy loads from the start it might be pretty simple to just raise floor of the cargo space a bit but for a common sedan that’s a whole another thing.



  • 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.
