Filesystem in UserSpacE.

Basically, the Linux/darwin kernel has a module called "fuse".
A userspace application is used to mount filesystems that are not supported by the kernel via this fuse module, like ntfs-3g (http://www.tuxera.com/community/open-source-ntfs-3g/) or exfat-fuse (https://github.com/relan/exfat).

fuse allows users to these operating systems use filesystems that could not be normally included in the mainline kernel for numerous reasons, such as copyright, patents, "just not fit the linux kernel standards" etc.

>>55769059

Just make the ball. It covers the whole HSV colour space so there's no need for sliders.

An extended and very interesting programming problem is generating colourschemes.

- Generate a 5 complimentary Colour Scheme from any input colour
- Generate a 5 Colour Scheme from the 5 most dominant tones in any image.

The problem is interesting because it blends art and programming. There's no definite answer to what constitutes a complimentary colorscheme and it varies by culture.

Simulate a game of tag using a multi-agent system.

Easy to medium, depending on your tools.

>>55769059

A really good classic threading challenge is making an elastic producer/consumer task queue.

There is a todo list and a done list. Consumers add tasks to the todo list and Producers take tasks, perform them and put them in the done list which can then be consumed by the consumers.

The system must work with an arbitrary scalable amount of producers/consumers and distribute tasks equally amongst the producers.

You'll have to know how to use Synchronized objects properly in Java which is something that 99% of Java programmers don't.

+ Bonus points for making the system resilient to faulty producers.
+ Bonus points for having the producers distributed over a network.

This is a great idea! You need to do just enough research to understand what the problem's asking, and the implementation might get a bit tricky. Exactly what I'm looking for in these challenges!

>>55770041
The challenge should be decrypting ROT cipher of unknown shift. Frequency analysis and fitting to standard frequencies for target language sounds pretty medium to me. Decrypting ROT-13 is easy. Hard would be breaking viginere ciphers with unknown key length.

>>55770080
so decrypting a caesar cipher? you could just display sample 'decrypted' text for each of the 25 shifts and see which one looks like it was successful, then select that one and decrypt the rest

pretty ez if you ask me

>>55770103
No, the trick should be displaying the most likely versions first based on letter frequencies, otherwise it's indeed pretty easy.

>>55768323
this is really cool list and I'm grateful that you're continuing to add to it

>>55770080
Just choose the shift with the most E's and call it a day. Even with frequency analysis it's easier than the other Medium shit like midi player and IRC client.

how about a simple genetic algorithm? Dawkin's weasel is probably simplest:

https://en.wikipedia.org/wiki/Weasel_program

But if you can do verlet integration you could probably do something like derpcar.

I'd also say add a travelling salesman solver using ant colony optimization. That can be pretty fun. Probably a medium. Had exactly that as a class project.

Also I'd argue that constructive solid geometry has a difficulty of fuck you. If you disagree with this, add NURBS 3d surface renderer or NURBS engine. At a basic level be able to render a STEP file that has NURBS surfaces. If you see cracks, you have failed. For extra fuck you points add interactive manipulation.

It was a major pain in the ass to get NURBS to work and it still is.

I also disagree with lambert's problem being fuck you hard.
