The problem that this solves is that current verified compiler efforts appear to be highly specific to both the language and the target. Once the semantics exists, you can either prove once and

I know a bit about how Michael Norrish dealt with this sort of thing in his formal semantics for C. For example, integer width is modeled as a constant, but one with an unspecified value. Other C level choices such as order of evaluation of function arguments are modeled using

Hi, I know there's been some talk about bignums already, this is similar to it, but not exactly the same. I'm currently using LLVM for my master thesis. The goal is to make a compiler for zero-knowledge proofs of knowledge protocols. This compiler should target embedded devices. There's a language called the protocol implementation language in which these protocols should be

Dear users, does any one have a code (S or R) to compute the binormal distribution (or the upper its quadrant area) other than the pmvnorm.

Hi, people! This is my first babble on this list, please be kind! :-) Last Tuesday, I wrote to the (likely) Webmaster of the R site to report a little problem, but also to ask for advice about how to get a bulk copy of the mailing list archives, from 2002 to now. While I quite understand that from Tuesday to now, there has been little time, and it is only normal that I did not receive a reply

Salve, I''m protecting hades with the tcpd wrappers and had no problems so far, at least none that I noticed. Today happend something strange.

Hi I'm trying to play a game which is not in the AppDB (yet) but when i try to run it blinks and shuts off. So I put it in the Terminal and it gave me this: Code: [iro at Hell ~]$ '/home/iro/.wine/drive_c/Program Files/Frater/bin/main.exe' fixme:win:EnumDisplayDevicesW ((null),0,0x33f214,0x00000000), stub! fixme:win:EnumDisplayDevicesW ((null),0,0x33f3d0,0x00000000), stub!

Hello. This is my first post here, as until now I wasn't missing any Windows program. As at the moment I can spare some free time I wanted to do a brief come back to Ragnarok Online. The problem that I found is that the installer crashes every single time I start the game (image link) (http://ompldr.org/vNXpheg), and then it becomes irresponsible (image link) (http://ompldr.org/vNXpiOA).

I don't need 3D acceleration but I'm interested in the nouveau driver because I hope it'll be able to properly set the mode of my card: currently nv is unable to make my card display 1600x1200 via DVI (it works OK via VGA but the quality is bit less stunning). So I compiled and installed it, but now I encountered a problem: it seems that (contrary to both the nv and the nvidia

One disadvantage of handling it through a script is that is will not be done by default. Most users probably don't know about the problem of burning batteries, as it is not very common. A potential problem with Eric Wilde's patch is that it is not general enough; some UPS models have an boolean OVERHEAT flag although they don't report the actual temperature. So the UPSOVERTEMP
