Lundi dernier j’ai anime une presentation devant une trentaine de collegues, au sujet de la methodologie Scrum. La methodologie Scrum est une methode agile de gestion de projet.

Les transparents de la presentation sont disponibles sur Google Documents, a ce lien.

J’ai effectue plus ample connaissance avec Moblin 2.1, le systeme d’exploitation base sur Linux (Fedora pour etre plus precis) et developpe par Intel, specialement pour les netbooks a base d’Atom. Je me suis servi de l’OS installe une clef USB, sur mon netbook Medion Akoya 1210 (a base d’Atom, 1Ghz, 1Go de RAM).

Premieres impressions

• c’est rapide, tres rapide, ca boote beaucoup plus vite que le Windows XP d’origine!
• a l’utilisation c’est vraiment fluide, les animations ne sont pas saccadees.
• premiers bemols: il ne s’agit pas d’un OS a “bureau” comme les OS classiques. On sent bien qu’ici l’accent est mis sur la mobilite, caractere propre aux netbooks.
• pour installer le clavier AZERTY: aller dans “applications”, puis “settings”, “layout” et installer le francais.
• j’ai essaye de passer en localisation francaise (toujours dans applications > settings ), mais le reglage n’etant pris en compte que lors du login cela n’a pas fonctionne pour la session courante.
• reconnaissance materielle: Wifi et ethernet OK, clavier et touchpad fonctionnent sans le moindre  souci.
• petit surf rapide sur internet, Flash est detecte et lu. Les pages s’affichent rapidement.
• un terminal est disponible dans le menu applications
• petite difficulte: eteindre le netbook. Oui je sais, c’est assez amusant, mais je n’ai pas trouve comment me delogger ou eteindre la machine. Finalement un appui sur le bouton on-off et l’appareil propose de s’eteindre dans 30 secondes.

Petits regrets

• le fait de passer a un OS sans bureau est assez deroutant. Mais en s’y donnant la peine on s’y adapte facilement.
• mon principal reproche: les reglages effectues pendant la session sur la clef USB ne sont pas sauvegardes. Autant je comprends que ce soit le cas pour un CD, autant pour une clef USB je m’attendais a ce que ca fonctionne. Je pense qu’il doit etre toutefois possible de sauvegarder des sessions sur l’USB, j’effectuerai quelques recherches.

Conclusion

La vitesse, legerete et reactivite du systeme sont vraiment appreciables et constituent les principales qualites de Moblin. Les ingenieurs d’Intel ont tres bien travaille!

Moblin est tres bien adapte aux usages d’internet mobile. Par contre pour un usage plus classique (bureautique ou loisirs) je reste sceptique.

Je pense que dans un premier temps je vais conserver Moblin sur un clef USB lorsque j’aurai uniquement besoin d’un acces rapide et sans risque sur internet.

Here is the bug I have reported this morning in OOo (Issue#107031)

Hi,

Here is a “bug” I encountered:

• I copy an image in the clipboard
• I launch OOo 3 on Vista / Intel Core 2 / localized in French
• I paste the image
• Right click > Picture > Picture > check “Vertically” and “Horizontally”
• (then the image in flipped on both directions)
• I save the document in Word 97/XP
• I re-open the document: the image is no more flipped (neither vertically nor horizontally).

I reproduced this case under XP/Core 2/localization in English with OOo 3 portable.
Yet, when I save in ODT format and reopen the file there is no issue, the file is flipped.

Thanks and regards,

Jonathan

This morning I tried to save some space in my computer. I found a file changelog.data in the folder <domain>\admin\data\ldap\ldapfiles of which size was more than 7 Go… This file is used by WebLogic, but I don’t know for which purpose.

I performed a head command on it, here is the output:

I assume this is a kind of binary/XML logger.

You can stop your server, delete this file (and another: changelog.index) and restart the server. The files will be created again.

Pointsec Protector Client is an application that blocks USB ports on a PC. This has an interest, especially for lamers who introduce viruses to great companies networks because of their contamined USB keys. But for developpers it’s very painful (unused resources and… other stuff 😉 ). Pointsec Protector Client is installed as “super admin” process: impossible to kill.
Here is the description of this application on its editor website:

Check Point Media Encryption secures sensitive corporate data and blocks incoming malware by encrypting removable media such as USB storage devices, CDs and DVDs and controlling activity (read, write and execute) on ports and devices. All device content is automatically encrypted in the background for a transparent end-user experience. Unique to Check Point, users can access encrypted media securely on unmanaged computers with no client installation. As the only device and port control solution integrated with a single endpoint security agent, Check Point Media Encryption simplifies compliance and reduces administrative overhead. Now supports Windows 7.

To get through Pointsec Protector Client, here is the way:

• you need be admin in your local computer
• Start > Control Panel > Administrative tools > Services > Select "Pointsec Protector Client" > stop the service
• open Windows Explorer, go to C:\Program Files, rename CheckPoint folder as XXXCheckPoint
• reboot your computer

You should have get rid of Pointsec Protector Client. I think this method should work on most applications started as service by a “super admin”, yet I have not tested.

Case:

You have to use an equivalent to “select for update” in Hibernate, for instance when you migrate en EJB entity to Hibernate.

Fix:

In your query, use the option LockMode.UPGRADE. For instance, you will have:

[java]sessionFactory.getCurrentSession().load(MyMappedClass.class, myPk, LockMode.UPGRADE);[/java]

Free.fr a ferme depuis hier son proxy. Jusque la accessible a l’adresse proxy.free.fr:3128, ce proxy etait bien pratique, pour sa disponibilite, sa robustesse, et sa vitesse pour les abonnes de Free.fr, surtout a la “vieille” de l’internet sur modems 56kbps.

Jusqu’a present, aucune explication n’a ete fournie quant a la raison de cette fermeture.

Question interessante d’un eleve il y a quelques semaines: quelle est la difference entre la Physique et la Chimie?

Reponse courte: la Chimie etudie les transformations de la matiere elle-meme au niveau de sa composition en especes chimiques, alors que la Physique etudie la matiere sans rapport avec les especes la composant: position, mouvement, temperature, charge, etc.

Plus precisement, en se basant sur un modele satellitaire de Bohr, la Chimie etudie les transformations de la matiere mettant en jeu des modifications sur les couches electroniques externes: reactions chimiques (oxydo-reduction, acido-basiques, etc.), ionisation, etc. On exclut le parametre temperature qui, bien que donnant une mesure du mouvement des electrons des couches externes, concerne en fait tous les electrons, quelle que soit leur couche.

La Physique etudie les autres modifications: deplacement, vitesse, temperature, forme, masse, electricite, fission, etc.:  ces dernieres notions ne se limitent pas aux couches electroniques externes mais concernent l’atome, la molecule, ou bien au contraire le noyau.

Neanmoins, plus on s’approche de l'”infiniment petit”, plus les distinctions s’estompent.

Context:

Client-server communication over JMS.

Explanation – Fix

The client JVM was in version 1.6, the server was in 1.5.
To fix the issue, the client must be run with Java 1.5.
Possibly, the client may laucnh the JVM with the option -Dsun.lang.ClassLoader.allowArraySyntax=true.

Context

I have to send JMS messages on queues on clustered servers: t3://firstServer:1234 and t3://secondServer:5678.

The destination queues are retrieved in Spring, thanks to a property like:
[xml]<property name="providerURL" value="t3://firstServer:1234,t3://secondServer:5678"/>[/xml]

Error:

I receive the following error:

[java]javax.naming.ConfigurationException [Root exception is java.net.MalformedURLException: port expected: t3://firstServer:1234,t3://secondServer:5678][/java]

Explanation and fix:

When you send messages on many queues, you must not repeat the protocol (here: t3://)! Fixing the issue is very simple: you have to remove the second t3:// in Spring property:

[xml]<property name="providerURL" value="t3://firstServer:1234,secondServer:5678"/>[/xml]
