Ask HN: Free shell hosting with compiling?

Free? A whole VPS is $5/mo.

hosteurope.de is pretty cheap (<$10/mo)

i could have done with a free one though. even 5$ a month I have to use 5$ worth... sometimes I want to use 5$ worth, but a lot of months i just want to forget its there...

i'm an exceedingly light user.
