How to fix the Unbound module Graphics in an ocaml project

From ~/pr/gitl/ocaml-gol In a constant effort to learn new programming languages, I'm currently trying to use ocaml , a free and open-source general-purpose, multi-paradigm programming language maintained at the Inria . It's basically an extension of Caml with object-oriented features. I'm mostly interested by its functionnal and pattern matching features but the module part of the language can be a bit difficult to understand for someone with little to none ML (Meta Language) background.   The error When trying to use the graphics module to create a graphical window and go just a little further than the simplest helloworld program, here is the result : If the project uses dune : (executable (name ocaml_project) (libraries lwt.unix graphics) ) with this code : let () = Printf.printf "Hello, world!\n";; Lwt_io.printf "Hello, world!\n";; Graphics.open_graph " 800x600";; The first times I built this project running the du...

Mrt-manager and the meteor update process

-

This day was finally lost; dedicated to a side project called mrt-manager, my first public project written in meteor, a javascript framework.

The first thing in a meteor day is to see if it need an update using the meteor list command. If some packages version are followed by an asterisk (*), I generally issue a  meteor update one. Today, this command failed.






Meteor starts downloading meteor-tool@1.3.2_4 then stops at 77% and throw the following error :
.meteor/packages/meteor-tool/.1.1.10.qt8nwl++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/lib/node_modules/fibers/future.js:259
throw new Error('Must throw non-empty error');
 After a while and some search, I finally found this stackoverflow.com answer and tried again. After a little check, I found my system free space was only 9 Mb.

After a short #apt-get clean, the free space's now 909 Mb and I can test again the whole update process. This take a long, very long time and didn't fix the issue : after downloading about 160 Mb of data, no progress bar anymore.

I also tested the meteor update --packages-only but most of the available packages were still upgradable. So, I decided to manually update indirect dependencies :
* iron:middleware-stack 1.0.11 (1.1.0 is available)
* practicalmeteor:chai 1.9.2_3 (2.1.0_1 is available)
* practicalmeteor:loglevel 1.1.0_3 (1.2.0_2 is available)
* npm-bcrypt 0.7.8_2 (0.8.5 is available)
Individual package update can be done with the meteor update <package_name> command.

The complete meteor update command finally went to 100% and continue downloading (more than 300 Mb) and the process finished with a complete up-to-date installation after the needed Selecting package versions and some individual downloading information messages.

I think the whole issue was because of a lack of space disk on the system partition. The final commit is finally showing nothing of this mess.

How to make a map of variant in C++

-

This code is used by RainbruRPG to store any scalar types in a single class instance. It's already in use since  revision 254  to save game states values when switching fullscreen or changing screen resolution. The map class It's basically a map of boost::variant using std::string as map key. I decided to use function template setter and getter to have a standardized exception-based error handling, but you could have multiple parameter-based specialized getter/setter ( void set(bool) , void set(int) ...).
