Locked/Archived Threads @ Project Euler

[whakamaru]

This subject is a good example of why the threads get locked . Maybe this forum should now be locked?
I am the only one on line? Nobody else here on the dark side of the planet? 10.00am and cold.

In another case, say someone uses a new/fun language, like LOLCODE and wants to post their solution?

I agree. I think there should be a listing of solutions in every language it has been solved in. If more than one solution has been created in a language, the most elegant should be listed.

And speaking of LOLCODE, the reason I found this site was to practice LOLCODE. Example code for Problem 1:

Code: Select all

That looks hideous. What's the point? Terrorizing grammarians?

The first disappointment I had after signing up was: conversation metaphor at the top level. What I hoped I'd see was a searchable/sortable collection of solutions, with conversations attached to individual solutions. I'd quite like to be able to see only solutions to a particular problem in e.g. APL or C++. This has practical application for me: this week, I'm working with language X. I know how to solve the problem in language Y, so... I suppose perhaps I'm barking up the wrong tree though, since this is what Rosetta Code is for. But there's also optimality. When you have to trade it, sometimes you want to optimize for one case or the other, and it'd be awfully nice to be able to search for "other solutions in the language I used."

For whatever reason, I'm mostly motivated to share my own solutions. Solving problems with locked conversations doesn't strike me as fun, and I'm not likely to come here to look for a solution to a practical problem if I can't filter on language. I usually end up other places when I'm looking for a solution to a programming problem, and I tend to end up on Wolfram math world and pages I've clicked through to from Wikipedia, when I'm looking for a solution to a math problem.

The locked thread thing wouldn't be nearly so big an issue for me if I didn't have to go through and solve a problem in order to see whether or not the thread had been locked... so if you follow, I have to solve the problem in order to find out whether or not I want to spend my free time solving the problem. Bummer.

If there's only value in having a certain number of solutions for a given problem, the value of individual solutions must be very high. "Killing the problem" after n submissions seems like it takes a lot of value out of the site. Instead, why not allow users to vote them up and down as on a site like StackOverflow?

In the thread for problem three, the first thing I see is a post that links to a page offsite which has a web application that solves the problem. To me this isn't any different than using a nice library which helps in a particular problem domain, since the source code is available. But for whatever reason, I don't care for this one. I think to myself: if this gets immortalized, I should be able to post my similarly "elegant" (b.s.) solution in Self too. I look for the vote down button, don't see it, and then look for the post button, and it's grayed out. Lame! I didn't make the party in time.

I might be back in a year or so. By then I imagine the site will have been fixed for newcomers, or the threads will all be locked:)

The solution I did for problem 3 in Self is still looking for a home, and it's not doing anything good for anyone while it sits on my hard drive, so I'll just leave this here

The problem I seem to have is that despite the popularity of the language I use (Python), a lot of the postings are for other languages, and while i can look at them, and especially the programmer's explanation, I can't really learn how to do that in Python. It would be great if the forums could be subdivided into categories based on the language used. It would also help to keep your forums shorter as there would be less for a user to have to wade through (which some would give up on and simply post a new reply). I do however realize the technical difficulties in this however.

Just to let everyone know these threads are regularly read by the admin team. Our non-intervention might appear as if we are not reacting or interested, but please be assured that we are constantly reflecting on your suggestions. I agree with much of what is being said, but I am sure you will appreciate that "fixing problems" retrospectively, especially for such a long standing webste (10 years now!), is quite a challenge.

Anyway, thank you for everyone who has taken the time to make helpful suggestions so far and please keep all the constructive suggestions coming.

Hi !

I discovered this web site few days ago and it is very interesting. I've resolved 25 problems with an HP50G calculator in RPL language.

Please could you add RPL for possible language in the profile form ? RPL is a sort of mix between Forth and LISP and this permits sometimes beautiful solutions. For exemple problem 18 and 65 are solved in 2 lines of code and 76 bytes. For all the topics I solved, threads are archived.

Thanks for this beautiful site !
