A friend and I are currently evaluating OCaml as the implementation language for a virtual machine. The interpreted language is yet undecided, but we expect it...
... What about an OCaml string or Bigarray for your data structure? This is perhaps not what you're after but I would recommend using LLVM to write a JIT in...

Hi, I'm using OCaml to implement a library for a network application where many distributed processes running and communicating. A process can generate and...
Here is a more concrete example, I think may people have encountered the same problem: Suppose process A opens a local file and get some file descriptor fd. It...

... No, you're not rewriting either map. You probably want to have a look for some resources on 'persistent' data structures to understand what's "really"...
I actually used a string * int key initially, but I thought that it was very silly to repeat the string a million times when once would suffice. Anyhow, now...
... I'd be surprised if the log is the performance bottleneck (you are in 64-bit?). ... You mean "ocamlopt -p" and "gprof". -- Dr Jon Harrop, Flying Frog...
... It shouldn't store the string, just a pointer to the string. On the other hand, you are right that there will be extra overhead (the tuple of two elements...
... Basically, everything is passed by reference in OCaml so you are not copying the data structure but referring back to it. After all, there is no point in ...

Hi, Thanks Dario and Richard for the suggestions on UUID. It seems that this problem can't be addressed universally with the plain composition of pid, ip etc....

Again, thanks both Dario and Richard for the detail explanation. Now I understand the problem better. If we were building a particular application, then there...

Hello, Dose anyone know how I may generate a arbitrary precision random number. The 64 bits is not enough. I looked at the Big_Int module but this has no...
... Call the 64-bit generator as many times as necessary and concatenate the bits in the results together to get a big random number. -- Dr Jon Harrop, Flying...

Or modify the interface to Random. Or, even easier, use another PRNG that's easy to pull bits from. E.g. here's a simple implementation of RC4 (written more...
