En parcourant les différents sites de médias, on peut noter qu'il existe une multitude de gestions des commentaires. Certains affichent les commentaires de façon linéaire, d'autres sous la forme d'arbre ou encore individualisés. Se pose alors le problème de la lisibilité lorsqu'un nombre important de contributions est envoyé. Tous ces systèmes ont leurs avantages et leurs défauts. Voici quelques exemples de systèmes de gestion de commentaires :

A la fin de mon précédent billet sur le libéralisme, j'avais terminé en pointant du doigt quelques termes moteurs de l'économie actuelle et fondateurs du néolibéralisme. Entre autre, j'avais initié une remise en cause du modèle économique basé sur la sacro-sainte concurrence. Cette bonne vieille concurrence qui, selon d'éminents économistes et prix nobels (Friedrich Hayek, Jean-Baptiste Say, Adam Smith... pour ne pas les citer), amène à une harmonie sociale et à un équilibre économique, à la condition, biensur, qu'aucun contrôle et qu'aucune régulation étatique n'aient lieu. Dans le cas contraire, chômage et inflation seraient alors inévitables. Voilà pour la théorie. En pratique, on en connaît plus ou moins les limites. On peut alors se poser la question de l'efficacité de la libre concurrence. Est-elle d'ailleurs saine dans tous les domaines ? dans les transports ? dans la santé ? dans l'éducation ? et dans... les télécoms ? Tiens donc, parlons des télécoms ! En plus, c'est un domaine qui est particulièrement riche en exemples (et puis je connais un peu mieux son histoire que celle de la santé).

Non pas celle d'Adam Smith, à travers laquelle le marché s'autorégulerait de manière naturelle, sans l'action de l'état. Une croyance fondatrice du monde néolibéral actuel et présente jusqu'à la tête de notre pays. Sarkozy croit en effet en l'éthique du capitalisme. Notre nouveau président espère ainsi que les patrons des grandes entreprises arrêteront, de façon volontaire, d'abuser des stock-options, de délocaliser pour maximiser les profits ou de piller les richesses naturelles.

I have written a small script which try to avoid the spam in comments posted in Dotclear blogs. It uses JavaScript events to detect any human activity (move of the mouse or press of a key) and send, using AJAX, a data to the server in order to inform it that the user is human. Then, the entire form is displayed and can be submitted. If no human activity is detected, the user is considered as a bot and can't see the entire form. It can't fill all the inputs and it will be rejected automatically by the server when the submit will take place because of a lack of informations.

The way to install this script is quite simple :

• Get the file http://www.sygus.net/atwork/dumbspam/dumbspam-1.0.zip
• Extract it and put the file form_ajax.php in the directory in which the current theme is. For example : /dotclear/themes/currentTheme/
• Open the file /dotclear/themes/currentTheme/post.php and replace the line which call form.php :

<?php include dirname(FILE).'/form.php'; ?>

by

<?php include dirname(FILE).'/form_ajax.php'; ?>

It should work for the new bots which try to post spam. If the bot has already come, and has saved the form's page in his memory before the installation of the script, it can go beyond this protection. In this case, another modification is needed. If the weblog is new, obviously this problem doesn't exist.

So the modification is the following : in the file form_ajax.php, replace the line :

<input name="c_nom" id="c_nom" type="text" ...

by

<input name="c_nomform" id="c_nom" type="text" ...

And in the file /dotclear/layout/prepend.php, replace the line :

$c_nom = trim($_POST'c_nom');

by

$c_nom = trim($_POST'c_nomform');

Yes, you need to modify the core of dotclear ! I don't see any other solution.

Since I turned back on my server, I wanted to be able to mount its partitions on my laptop. I first tried nfs, but this program couldn't share each partition. Indeed, one of them was a fat32 partition and it appeared that nfs was not capable to share it. Actually, I couldn't see any files. The other problem I met with nfs is that I was not able to mount the partition through internet, in the aim to acces to my movie/music/share directory everywhere. I didn't find any solution to that, so I gave up.

After some research, I found a new way to share partition : by using a ssh filesystem. The implementation I installed is sshfs which is based on the API fuse. It can be found on the package list of Debian, or here It works very well and has the advantage to be secure because of the use of the protocole SSH. The latency is quite good and the bandwith depends naturally of the rate of the both endpoints of the connection.

Currently, I'm listening music 130km away from the server.

The last sunday, I made a one-day trip in the north of Ireland. We were seven to go : one spanish, one german and the rest of french. Our two cars first stopped in Londonderry, in Nothern Ireland, for the morning. Before to be there, I thought it was an ugly city because of the fight between catholic and protestant. Remember you that Londonderry is on the borderline between Ireland and Nothern Ireland (yeah like Dundalk), and this city is known to have a not so beautiful history (Bloody Sunday for example). I was therefore surprised to see a city with ramparts, gates and the town center between these ramparts seemed to be a very nice place. I was wondering why this city is sometimes called Derry and some other times called Londonderry. This is again because of the opposition between catholic and protestant. The first one call this city Derry and for the other one, it's Londonderry. But we were here at 11:00 on a sunday and everything was closed. Absolutely everything ! Impossible to find any open pub or café. Fortunately, after 20 minutes of walk, we found an hotel (4 stars hotel with limousine in front of, but not for us...) and we took a coffee. 6 pounds for seven coffee and tea, that could be worst

After this break, we left the Nothern Ireland and we came back in our Ireland, in the county Donegal. We made the next stop in a little beach called Inishowen Head. A lovely place, and nobody was there except us. The sun was shining and we felt a little bit warm ! We went then to the highest point of Ireland : Malin Head. A nice place with cliffs, but it began to rain and to snow. We didn't care about that and we were fighting against the strong wind. This remember me the Pointe-Du-Raz in France, in Bretagne. This is the westest place of France and there are also cliffs and strong wind and rain We tried to eat outside between two showers. It was a half-success because after a while, we decided to finish eating in the cars.

Then we went, with a bit of difficulty due to the bad irish roads and indications, to Grianan Aileach which is a moutains, or maybe a only bump (it's so difficult to call something a moutain when the top is only at 250 meters...), and on the top there is a stone fort. From this position, we had a pretty good vue of the surrounding landscape. But, it began again to snow and we felt awfully cold. So we came back home. We were in Dundalk at almost 21:00.

Finally it was a very nice trip. And in spite of the weather, we all enjoyed this day. But the next time, I should avoid making a party at home the day before to make a trip. Because sleeping 2 hours is not really sufficient !

Je me suis lancé dans un script permettant de connaître tout un tas d'informations relatif à l'utilisation d'un serveur hlds (hl, cstrike and co). Pour le moment, il est possible d'obtenir un graph d'utilisation du processeur et de la mémoire. Comme pour ScanGraph, le graph obtenu est totalement paramétrable (en longueur, en largeur, en précision, etc.). Et puis, comme je suis à fond dans le perl en ce moment, les graphiques sont biensur réalisés par l'API GD de perl. Vous pouvez voir la démo ici : HLGraph en action ! (si vous voyez rien, c'est que le serveur hlds ne tourne pas

Voici ScanGraph, un programme réalisé en perl qui permet de connaitre d'un coup d'oeil les temps de latence de certaines machines. Une démo de ScanGraph est visible. Cette page fait une simple requete sur le repertoire des images créées par le module GD de perl. Biensur ce programme n'a pas la prétention de concurrencer les outils de Tobias Oetiker, je l'ai simplement réalisé pour compléter le programme ScanLan. En effet, je préfére réaliser un programme qui gère tout lui même, plutot que de dépendre d'outils tels que Smokeping, fping, weathermap ou encore mrtg. Non pas que ces outils soient mauvais, au contraire, mais il n'est pas commode de devoir tous les installer pour profiter de ScanLan.
