In a way, Project Euler was years ahead of its time. It's a set of problems for aspiring machine learning and data science specialists. They should really update their description.

Re: Project Euler
#92I guess I'm becoming an old fart. I used to like programming puzzles, challenges, things like this. But as time marches on, I realize that the real-world problems I have to solve are already so challenging and require enough critical thinking, that I'm best served just focusing on them. Between family life, doing real-world challenges for income, downtime to breathe, diverse hobbies for the spiritual good of my person, I just don't see how to fit in Euler problems and other similar endeavors. Perhaps if I was a teenager again, I'd be jumping into them with much enjoyment.

I don't think it's unreasonable to expect it. E.g. clang -O1 ( https://godbolt.org/g/7qzSF9 ) is able to use the closed form for a sum on a simple C++ loop. It's not unreasonable that a language with deeper introspection could identify more closed forms. I agree that I don't think the Haskell maintainers would put this specific example in, but I wonder whether they could build it up from simpler primitives.
Haskell optimizer does not feature an arithmetic Oracle nor polynomial optimizer. It cannot even optimize Peano arithmetic much less a series. This might be fixed some time or never. There is little push for ultimate performance and actually identifying arithmetic forms in recursive loops in the front-end is hard. (Heck it sometimes fails to tail optimize.)
I'd be interested to see how this weighs out in 5-10 years. Since there's no I/O here, I don't see why a clever compiler writer couldn't optimize this whole expression away at compile time, generating an executable just prints a constant.

I am the same though I'm only 30. I no longer seek out puzzles but to solve interesting real world problems. The time you put into a challenging Euler puzzle, you can use React/Rails/NodeJs/Go/Rust/lang du jour to solve real world problem, helping real people.
Also as a liberal arts in programming, Euler, is fun in the sense of a well done proof is fun in math. If that is your thing you'll enjoy Euler, otherwise as in most programming you will brute force your way to a solution.

Project Euler is nice for math problems. It has little real world value for developers. The first ones can be a nice hands on introduction to problem solving.
Re: Project Euler
#96I really like to use project euler when I want to learn a new language. Exercises are sorted more or less by difficulty, at least for the first 50-100, and are completely langage agnostic (you just need to answer a question in a text input). It's also very good to learn algorithm and maths. Some problems can even be solved without any programming. And for some, a certain amount of math is necessary to have a efficien…
(They do ask not to share the solutions.) But nice job translating them :-)
That's not me, but I found those translations very useful a few years ago! Hope it can help someone.

A bit of a plug, but you should check out this thing I built! Go to https://hackattic.com - It's just a test of an idea, but I wanted to show people it's possible to come up with no-nonsense, more real-world-y challenges. I've never, ever really like the typical CS challenges proposed everywhere.

I really like the book “Concrete Mathematics”. It might be a little hard going without much maths background, but it is filled with these kinds of tricks.
Author(s)?
Not the same person but I guess he means the one by Graham, Knuth (yeah that one) and Patashnik.

It's normal to lose interest in hobbies when new ones take over
