Hi,
While I was writing a sort of password manager for my personal use (in Haskell) — actually, a friend of mine was doing the same in Java, so there was some competition — I decided that just printing the password in the terminal wasn’t enough, at all. That’s why I decided to look at [...]
Hi,
I’ve just found out two libraries which seem to be very interesting.
The first, CAMP, is an introspection library for C++. It appears to be well-thought and easily usable in concrete projects. Indeed, it isn’t (at all !) intrusive, which means you don’t have to modify existing classes to expose them to introspection. The example given [...]
Hi,
I’ve written a little boucing ball program in OCaml with OCamlSDL.
It can be used as a basis to write a Pong game, or any 2D game with a ball bouncing here and there on the screen.
You can download it (images, font, source code and Makefile included) here : bbsdl.tar.gz.
Don’t forget to tell me if you [...]
Hi,
Several days ago, bluestorm and I started working on monads-related stuffs for Batteries, so that we’d be able to provide a good API for writing and using monads in Objective Caml.
Well, we’ve now written the basis of the future monad-related functions and modules in Batteries.
Of course, we’ve introduced two key monads, keeping Batteries’ spirit : [...]
Hi,
Jon Harrop has written many articles in his OCaml Journal, and some of them are related to low-level optimization, which is a very important topic for OCaml developers, as OCaml is a fast functional language and can race against mainstream languages if we help him with our way of writing code, using the compiler, etc.
These [...]
Hi,
I’m writing this post because I want to thank and encourage the OCaml community. Indeed, there are many really *great* news this week that you may have seen if you read either Planet OCaml(Core), the Caml mailing list or both.
OCaml and Debian — The first one is a very good one for making OCaml more [...]
Hi,
It’s been some days I was working on a very interesting project…
Many of you probably know Internet Relay Chat (IRC), in particular the Freenode network. You can access it through an IRC Client, the most known being XChat. The host is irc.freenode.net, on port 6667.
Some of you are used to bots on IRC, often provided [...]
Hi,
Have you ever tried compiling with either ocamlc or ocamlopt with the -dlambda option ?
Compiling the following code :

let f = List.map (fun x -> x+1)
let print_list = List.iter (fun x -> Printf.printf " %d " x)
let _ = print_list ( f [1;2;3;4;5] )
give the following “lambda code” :

Today, we’ll give a whirl at the Rope module of OCaml Batteries Included.
What are ropes ?
Ropes are better strings (but heavyweight) :
The length of a rope can be determined in constant time
appending or prepending a small rope to an arbitrarily large one in amortized constant time
concat, substring, insert, remove operations in amortized logarithmic time
access [...]
I’ve been recently involve in an amazing project, the first multithreaded game engine with real performance on multicore processors.
We are all aware of the lack of video game performance on multicore, this engine claim linear performance scaling on manycore processors.
About x4 performance gain on a quadcore HT corei7 (see here) . Independent results with cinebench [...]
