  • In general, setting up a client with POP3 rather than IMAP will move all the emails from the inbox to the client. Once they are in the client you can decide how to backup the archive, there’s plenty of options with varying performance and memory footprint. That sounds pretty much like what you would like to do in general.

    Just for completeness: That of course also means that syncing to several devices and backups are now your problems to solve.

    In any case, the initial download will take a long time either way if you have 20+ years and 10s of GBs of data. No way around that.


  • I don’t think you are paranoid. This technology is creepy as hell. Almost all cars are connected nowadays and send data back to the manufacturer’s server—visible or not. In the best case it’s just the service history, in the worst case live positions and more. Some cars stop working if the server is shut down *cough. Cameras equipped to unlock based on a face record biometric data. And honestly, would you trust your car manufacturer (!) to handle your biometric data?



  • From an environmental physics point of view, this is not very weird: Warm air holds more absolute amount of water, leading to stronger downpours and longer dry periods. One could also say, the world is getting warmer and this a little “more like summer”. And strong rains converts to strong surface runoff. In other words: Strong rains causes your streets and fields to flood and that water raises the rivers rather than the soil’s moisture. And there we go: The soil is getting drier although there’s more total rainfall.




  • I don’t find this convincing. Everyone knows how easy it is to click “yes” without actually knowing what’s behind it even reading it at all. There’s a reason that “I have read the terms and conditions” is the most common lie on the web. Also, no one will read a lot of information. So adding AI sounds great, doesn’t it? While this is a technical opt-in, it is still really close to an opt-out.

    And then the ML generated code. I am aware it’s anecdotal evidence and might not mean anything but every time I tried Ubuntu, I deleted it after a few days because I found the bugs way too annoying after hitting too many road blocks. So if a buggy prone desktop environment additionally accepts ML code, it makes me suspicious and wanna stay away from it.


  • Exactly at the speed of light, the γ-coefficient would be infinite and so would be the time dialation. The eigen time of the moving person would thus be infinitely slower than the non-moving person. From the perspective of the stationary person, the time of the moving person would stand still and thus the person would never say anything. Very close to the light speed, when the coefficients are large, this problem eases but persists. The stationary person would have to wait for very long (and use a massive Doppler shift of the moving signal) to perceive something. At the end of the conversation, it will have lasted much longer for the stationary person, spending years on this. The twin paradox would basically kick in as well. If the moving person is at a speed too close to the speed of light, the stationary person might die before the conversation is over—assuming the stationary person is not immortal. That is kind of a very slow motion, yes. What a dedication, spending a lifetime on a person who can’t slow down ;-) Funny enough, from the perspective of the moving person, the effect is reversed.


  • The only thing that really got me going was small applications I had some interest in. Writing games I will not play never kept my interest up for long. So I’ve been building mini tools I used for teaching numerics classes in meteorology (Python, Julia, Fortran, C) or code I would be using for some tinkering with microcontrollers or similar (Python, C++) when using new languages. For me personally, some iconic projects were a CO2 sensor with an attached display, or very simple internal gravity wave ray tracers. But that’s likely not what you’d be interested in. So without trying to suggest specific applications for you (many good examples in the responses :-) I’d advise to do something you’ll have fun with. Get yourself a small project that generates added value for you specifically (and fun is great added value in my eyes).



  • Maybe the security expert could read the readmes in the repos first. From the iOS app repo:

    The initial development release has reduced security, privacy, availability, and reliability standards relative to future releases. This could make the software slower, less reliable, or more vulnerable to attacks than mature software.

    And further:

    If you’re planning to use this application in production, we recommend reviewing the following steps: […] The Pin storage configuration matches your security requirements, or provide your own by following this guide Pin Storage Configuration […]

    So the text hints not at design flaws but at facts that are already stated in the readme. <irony> Plus, the major source for the article is Pavel Durov, who’s messenger is of course a standard in security and privacy. </irony>

    So there seems to be no news but a lot of speculation by Durov instead.



  • I wanna give a shoutout to Manjaro, an arch based distro with a cascading testing cycle for better stability. That being said, I am using Arch and Manjaro for about a decade now and never really had any stability issues (in contrast to my tries with Ubuntu). The arch wiki stays one of the absolute best resources for Linux users on the internet, the rolling release ensures cutting edge Software, the AUR makes it very easy to provide community built packages. And then there’s Debian. Definitely my choice for servers.



  • SEPA is the direct banking standard in Europe. Basically every transaction between banks follows that standard. If you’re doing business in Europe, that’s the most direct way you can go. Many other companies and their transactions follow the SEPA standard somewhere anyway. An SEPA mandate is pretty safe for the customer, too. It can be canceled by the account owner at any time. It does not have any additional insurance layer, though.
