Hi!
I’m Valeriu — still the kid fascinated by building the world; just with better tools. Lately, some of them are about making math visible and easy to get.

Fully dynamic JSON handling in Scala
For some time now I (badly) wanted to be able to work with JSON structures in Scala just as easily as in JavaScript (though even in JS you need some wizardry to be able to to this elegantly). I don’t particularly like Json4s since I feel that it’s overly complex (no, I don’t want to…

Universal getter for plain JS objects.
Many times in JavaScript we have to reach deep into objects to access fields that could possibly not be there at all; for example let’s assume I have a JS object called options into which I’ve just read an entire JSON configuration file. Trying to access a field like options.application.cache.enable directly will potentially fail (e.g.…

Visualizing Git diffs in Meld.
Here’s a quick way of configuring your (Linux-based) Git installation to use the excellent Meld program by default for displaying/editing the outputs of the git diff and git merge commands (e.g. git diff «filename»). Install Meld …if you haven’t already (note that we assume Git to be present): # on Debian-based distros (ymmv) sudo apt-get…

Luca
Again, I have to break the tradition to only post programming-related articles. This is because on the September 22nd 2012, this guy said hello. I know I was a bit late in letting him say say “Hi!” on the web too, but daddy’s been really busy and he forgot :(. But have no fear sonny-boy,…

Quickly filtering large lists of texts.
Recently, I had to make a mock-up of a filtering function (something I need for a project I work on) so I can show-case it around. And since this mock-up seems to impress some people, I decided to share this function with everybody so others may enjoy the “loot” :). Briefing The function (i.e. filter())…

JS classes for the masses.
Following on an older post of mine, I decided to write a new article about an(other) implementation of OOP Classes in JavaScript. This is something that brings a lot of value from very few lines of code and I want to share it with everyone and see how it can be improved. First let’s see…

Loomiere 2.0.1-beta finally out!
All right! I finally got around to releasing this code to the public. I won’t say much now (since I’m tired) but I will say that this software has been functioning in production environment for over 1 year and a half serving all the video content available on the romanian website http://peteava.ro (about 800 TB of data each…

Lua-TTyrant: a TokyoTyrant binding for Lua.
Some time ago I started a small project to implement a C-to-Lua binding of the TokyoTyrant library, called “lua-ttyrant“. A few days ago, while working with a script that was actually using it, I decided to polish it up, finish it and eventually submit it to be included in the LuaRocks repositories. Given the fact…

A simple(r) approach for class-based OOP in JavaScript.
Like others before me, I found JavaScript’s prototype-based OOP support – while very powerful – quite cumbersome in some situations where I needed a certain structure or hierarchy of objects, situations in which one quickly comes to the conclusion that the best answer would be the concept of a Class. However, while I am well…

Command-line option parser in JavaScript.
Here’s a small but very effective command-line option parser written in JavaScript (uses NodeJs). You can get the up-to-date source code at http://gist.github.com/982499. I wrote this because I needed it for a project and I did not think it was worth it to install some npm package just for this. The comment should explain most…
