  • Came her to say this. Safe programming languages? Yes, plenty. Safe and low-level? Well, modern C++, kinda, if you do your homework and follow some rules. I don't know any other tbh.

  • Are there good uses for the blockchain?

  • Cryptography based BankingThere are lots of good reasons to not base money transfers on arbitrary numbers that you need to keep track of. Right now, banks have to make sure themselves that a transaction is legitimate and may never lose record of it, otherwise money just disappears to someone's damage. With a blockchain, you get a hard proof a transaction took place. Whether that's to proof you paid for something or for law enforcement to know you bribed a certain someone, I firmly believe it's better than what we do now. If my bank told me tomorrow I have no money or claimed I spend it all on terrorism, I would be in a pretty bad spot.

    Ownership and Track RecordsWe live in a time of misinformation and AI generated bs. With the help of a blockchain, you can keep track of who posted something first, i.e who has the copyright or started some false information campaign, and also who generally spreads bs. This of course also works the other way around: Who has a good track record and posts trustworthy news or original content? And again, you wouldn't necessarily have to rely on a single institution to play nice, not delete content etc. Although admittedly, it's much more complicated this case, because you have to expect bad actors much more than in banking. Banking is infrastructure, this can be a lot of things (science and/or opinion and/or legal stuff...).

  • Second this. What you need for high quality media is space, not speed. For any single stream, network and drive will be fast enough anyway. Your typical HDD offers like 4-6 times the bandwidth that a regular Blu-ray can provide. You can get 8TB HDDs for the price of 2TB SSDs. Random access doesn't matter for that application.

    You might want to invest in redundancy and use a RAID 1 or RAID 10 array, depends on how valuable that media is to you or how long it would take to recover in case it's lost. A simple solution would be a btrfs software RAID, in case your are after something like a Linux home media server with Jellyfin.

  • I want to believe we have gotten better and "wehrhafte Demokratie" is not just a throwaway slogan. In sum, "only" about 25% are voting populist, be it put of protest, spite, for your own benefit ot out of crooked conviction. That means 75% are still somewhat reasonable and I want to see this as a positive thing.

  • The only ads I'm exposed to are influencers and product placements. I recently bought something because of an influencer the second time in my life (excluding their own merch). I think I can manage.

    I do fall for sales tho. Bad impulse control.

  • There is a Python interpreter written in Rust. It's apparently intended to (besides being fast an all that) make Rust scriptable.

  • How Good at Math Does a Programmer Need to Be?

    Jump

  • I totally agree. I think maths should start with games in elementary and cover history and applications as soon as you enter middle school. (Keeping games of course, how is there no redstone in the maths curriculum?!)

    And I know that my rambling won't convince people to immediately shake off the system induced maths fatigue, but I'll never stop encouraging people to give it a second chance :)

  • How Good at Math Does a Programmer Need to Be?

    Jump

  • As others have mentioned, how much and what kind of math you need depends heavily on what you do. And while I wholeheartedly encourage you to do what you enjoy, be it with or without maths, I would like to offer another perspective: A loveletter to maths.

    Math in general gets a lot easier and more fun the longer you do it and the more interest you can build. Often the people that teach math are extremely good at it, and maybe because of that they suck at explaining it. There is a lot to doing it right.

    First of all, I think you need to build excitement. Math strives to describe the world! Math is the foundation of science, math is history, and many of the concepts and techniques arose out of necessity... Or sometimes spite! There are many funny stories or interesting people behind the formulars and concepts you encounter. Learning why the hell some math was even invented and how the guy or gal got the idea is 1000x more interesting than just getting an example for the application of it. It helps you remember stuff.

    Then there are a dozen ways to explain every single concept and then some. You will find some much more intuitive than others and the sum of them will sharpen your understanding of them. Looking for different explanations for the same thing can be a great help. Did you know many things in maths where discovered multiple times? That happens a lot, because even brilliant mathematicians don't properly understand each other, or even themselves.

    Another thing you should do is to always develop your vocabulary for every domain/concept you encounter. People will throw around made-up words and symbols like no tomorrow. Often, there are simple concepts behind them, hence they are casually abstracted away. You need to understand the concept and then translate it into your own words and then draw a connection back to the made up stuff. Maths is a lot like programming. 1 + 1 is just a function, returning a result. So are integrals, formulas in vector algebra, and every single damn other thing in maths. Just follow the chain!

    And finally, there are also some amazing insights hidden in maths. Gödel's incompleteness theorems might send a chill down your spine once you grasp their implications. Computability and information theory will shape your view on the world and yourself.

    I went from getting Ds to Bs to advanced theoretical CS courses and you can do it too. You don't have to, but you can.
