Strange Problem
I've had issues with all my sites lately including this one that have seemed "strange". Well I know what's happening now, but not why. For some reason, it has become nearly impossible to create a file or a directory with a purely numeric name. Using touch, mkdir, or even a C program to call open or SYS_open fails (errno==2) if the file name has nothing but numbers in it. Any file name that has at least one character that isn't a number works like you'd expect. This happens on all file systems.
I've upgraded the kernel. The fact that it occurs on all file systems and even when directly calling the kernel makes me think it is not the C library or a corrupt file system. There are no loaded modules in the kernel (ext3 built in along with everything else needed).
Here's a twist. The debugfs program can create directories with numeric names. I assume it is doing some direct manipulation to accomplish this -- more evidence it isn't a file system issue.
Not sure what to do next. My colocators want to wipe my hard drive and reinstall Linux (must be Microsoft trained) but I've told them no -- I'd figure something out eventually.

Tools you didn't know you needed
See
http://www.evilmadscientist.com/article.php/obscuretools for 5 electronic tools you didn't know you needed. Truth of it is, except for the IC popper, I could do without these, although your mileage may vary (although I have used real vacuum tweezers and they are good for handling tiny parts -- haven't tried the unpowered kind). The odd tools I use all the time are:
- Thermal wire strippers -- these are amazing. I have a Teledyne Stripall, but they are horribly expensive ($400-600); there are other brands out there too like Hakko. Maybe you can get lucky on E-Bay
- Vacuum desoldering tools -- calways heap on E-bay
- Jeweler's loupes - get these cheap at Harbor Freight (around here, they are at the register)
- Step drill bits - another item that is either ridiculously cheap at Harbor Freight or ridiculously expensive everywhere else
- Nibbler - One of those metal punches that take out a chunk of metal. Great for making LCD holes and what not (case modders have made these popular again)
