    Prototypage rapide sur Android avec Processing

    En m'intéressant au prototypage rapide d'application sur android, et j'ai trouvé une solution simple avec Processing (ça a l'air assez simple en Java aussi).

    http://wiki.processing.org/w/Android

    Sur Mac, avec la device Android pluggée en USB et le mode USB debug activé:

    1. Télécharger la dernière version de Processing (2.0b6) : http://processing.org/download/
    2. 2. Télécharger le SDK Android et le placer dans /Applications
    3. 3. Exécuter /Applications/android-sdk-macosx/tools/android et installer: Tools, Android 4.2 (API 17), Android 2.3.3 (API 10)
    4. 4. Lancer Processing
    5. 5. Sélection "Android" dans Processing, disponible en haut à droite dela fenêtre en appuyant sur "Java"
    6. 6. Une nouvelle fenêtre s'ouvre, charger un example (dispo dans le menu "File")
    7. 7. Dans le menu "Sketch", compiler et exécuter l'app en choisissant "Run on Device"

    Hier, les exemples (Particle, compass, ...) ont fonctionné de suite sans aucune modification.

    Le wiki est rempli de bonne info - http://wiki.processing.org/w/Android - et une large contribution a été apportée par la librairie Ketai: https://code.google.com/p/ketai/

    Un bouquin est aussi dispo sur PragProg, avec une introduction à Ketai et 20 projets basés dessus: http://pragprog.com/book/dsproc/rapid-android-development

    Open Source is a Philosophy, Not a Checkbox

    TL;DR : open source is a philosophy, not a checkbox. Find more collaborators, not customers. The future is open.

    Packages debian/ubuntu for Rivendell 2.2.0

    Rivendell 2.2.0

    Les paquets de Rivendell 2.2.0 pour Debian and Ubuntu sont maintenant disponibles sur le dépôt Debian Tryphon pour :

    • Debian : squeeze/stable, wheezy/testing, sid/unstable
    • Ubuntu : lucid/10.04(LTS), natty/11.04, oneiric/11.10 et precise/12.04(LTS)

    Les plateformes i386 et amd64 sont, comme toujours, supportées.

    Support de Wheezy & Sid

    La librairie Qt3 n’étant plus supportée officiellement par Debian, nous fournissons maintenant les packages Qt3 pour wheezy et sid [en].

    Rivendell est donc maintenant à nouveau disponible sur Debian wheezy (la future version stable) et sid.

    Hotkeys

    RdAirPlay a besoin d’un fichier fourni par le paquet libqt3-headers. Ce paquet est maintenant suggéré et non requis, car il installe énormément de dépendences.

    Installation

    Vous pouvez obtenir un Rivendell fonctionnel en quelques minutes :

    Etape 1 : Ajoutez le dépôt Debian Tryphon à vos sources Debian/Ubuntu

    Etape 2 : Installez un serveur MySQL : sudo apt-get install mysql-server

    Etape 3 : Installez à la fois Rivendell “server” et “station” : sudo apt-get install rivendell-server rivendell

    Etape 4 : Ajoutez l’utilisateur qui doit utiliser Rivendell dans le groupe du même nom. Par exemple, pour vous ajouter vous-même : sudo adduser $USER rivendell

    Au passage, vérifiez que le même utilisateur est indiqué dans /etc/rd.conf à la ligne AudioOwner. Si vous utilisez sudo pour l’installation, cela sera le cas. Cette information sera bientôt (à nouveau) paramétrable à l’installation.

    Etape 5 : Quittez et relancez votre session (Gnome, KDE, etc …) pour prendre en compte le nouveau groupe et les permissions données au groupe rivendell lors de l’installation

    Etape 6 : Lancez rdadmin qui va créer la base en vous demandant le login de l’administrateur MySQL (root) et le mot de passe (choisi pendant l’installation de mysql-server).

    Etape 7 : Lancez rdairplay et le cart Test et appréciez

    Coulisses

    Comme l’ensemble des projets Tryphon, les sources de ces paquets sont accessibles sur http://projects.tryphon.eu/projects/rivendell2-debian.

    Le wiki du projet donne quelques indications pour reconstruire les paquets.

    Residency at Unit One

    I’m doing a residency at Unit One in Allen hall at the University of Illinois for all of this week. If you are around, then please stop by! I’ve created a quick LoL Shield animation for my door to tell you whether I’m in or not (source for that is here, and uses the EEPROM if that’s interesting to you, so I just have to turn it off/on to toggle it).

    Sunday, October 14
    7pm – Opening Program: Meet Jimmie Rodgers (south rec room)
    Jimmie Rodgers is a full time hacker, artist, musician, open hardware developer, and techno-nomad. He travels around the world teaching people how to make things. He does everything from digital to physical art, but everything he does is either open source or creative commons. He’s best known for the LoL Shield (an Arduino shield with lots of LEDS), and for various circuitbending and music projects.

    Monday, October 15
    7pm - Atari Punk Console workshopbuild a basic synthesizer or optical theremin (south rec room)
    The Atari Punk Console is an easy to build synthesizer that you can use to make lots of fun sounds. This workshop will include all the parts you need to make the synthesizer, or even to create your own optical theremin! Bring your own case – Altoids tins, cigar boxes, or anything else that has at least the internal volume of a pack of playing cards.

    10pm – tea time: building custom electronic instruments (guest apartment)

    Tuesday, October 16
    7pm - Building Contact Mics (south rec room)
    Learn how easy it is to build your own contact mics. This workshop will have everything you’ll need to build a mic. We’ll then explore finding sounds in everyday objects, and some fun things to do with those found sounds. If you have your own amp, then please bring it!

    9:30pm - Depression Meetup (guest apartment)
    Depression can be a hard burden to bear, both for people who suffer directly, and people who help to support them. Come and talk about it with Jimmie Rodgers, who has been dealing with depression since he was a teenager. He has spoken at a number of events about depression, and has been an advocate of speaking openly about its effects and treatments. Many people suffer from depression, but there’s no reason to suffer alone.

    Wednesday, October 17
    7pm – Circuitbending (south rec room)
    Circuitbending is the art of modifying toys, synthesizers, effects pedals, and anything electronic that makes noise or shows video. You’ll be bending a Staples Easy button, and learn enough of the basics to go exploring on your own after this workshop.

    10pm - Noise Night (main lounge)
    Bring your electronic instruments, noise makers, mixers, amps, effects pedals, hookup cables, and anything you can make sound with. People will hook their noise makers together and just jam. An open mind and tolerance for crazy sounds encouraged.

    Thursday, October 18
    7pm - Building (and playing) quality didgeridoos out of PVC (south rec room)
    Learn how to quickly and cheaply make good sounding didgeridoos out of PVC. You’ll learn how to build and play them in this workshop. Advanced techniques will be covered, so you can continue to make nice didgeridoos long after the workshop.

    10pm - Drone Night (south rec room)
    Bring your acoustic instruments, drums, didgeridoos, singing bowls, and anything else that can make a trance-like sound. We’ll sit around and play the didgeridoos made in the previous workshop along with any brought instruments. Beginners welcome, and experimentation will be encouraged.

    Noisebridge Birthday – 4 years of Excellent Failures

    It's been 4 years since we opened our doors on October 1st 2008 at 83c Wiese Street, and a little over 3 years in our current location at 2169 Mission Street. Since then we've done a number of silly things, gotten in trouble, provided internet freedom, become extremely angry at people, been to outer space, come together as a community of techno misfits, and started our own republic. Above all else we've shown time and time again at failing in the most excellent ways. And some how we still haven't managed to burn the building down, (fully) chop off someone's limb and get horribly sued, or be the target of a government raid.

    On the night of Sunday October 7th, come and celebrate the fact that we are the most oldest (and still operating), most resilient, and probably most open to everyone hacker space in San Francisco.

    We'll be at the space from about 20:00 onward with paper and tinfoil hats. There'll be some sort of music. Surprise guest appearances by Pedobear. I'm sure you could donate some Bitcoin on food and drink, if not BYOB. This'll be a very informal gathering so don't expect the theatrics from parties past. Think of it as a hack night with a general theme of party, socializing, and crying into each others shoulders remember 4 years of excellent failures.

    Toorcamp with Noisebridge

    Toorcamp is a hacker/maker conference and camp, the next one is coming up August 8th through the 12th and takes place on the Northern Washington coast in Neah Bay. Hacker camps generally consist of talks and workshops, plus the fine tomfoolery that hackers can come up with when faced with the great out doors.

    Just like last year, Noisebridge is planning a camp, The People's Republic of Nosebridge. Within PR0N we'll be hosting the Welcome Pavilion, Light Tower of Consenso, Occubus, Drama Cafe, and a vomitorium.

    Interested in going to Toorcamp? Want to possibly camp with PR0N? Are you an excellent human being? Great! Get on our mailing list and ask how now!

    Mitch Altman is no longer welcome in Canada?

    Ever been kicked out of a country before? Well, it sucks.

    I’m in the middle of my Hackers On A Train Workshop Tour, giving my popular Learn-to-Solder and Arduino-For-Total-Newbies workshops at 22 hackerspaces near Amtrak stations, and going to 4 conferences, over a 53 days. All by Amtrak. That was the plan, anyhow.

    I was scheduled to give a talk about the hackerspace movement at the WorldFuture 2012 conference this Saturday. While there I was going to stay with my (academy award winning) friend Chris. It was going to be a really wonderful 5 days in Toronto.

    To give the workshops, I’m traveling with a rucksack full of clothing and toiletries, my laptop, camera, and two huge suitcases, 50 pounds each, full of workshop stuff, including kits for teaching.

    The train to Toronto from Syracuse, NY, stops at the Canadian border for customs and immigration. Everyone has to get out of the train with all their stuff. The line moves rather quickly, and when it was my turn, the Canadian Border Patrol wanted to have a look at my huge bags. After much polite discussion, there was no way that I could assure the CBP that I wasn’t going to sell the kits in Canada.

    The CBP folks politely offered a suggestion that I could leave the workshop stuff in the US, and then come back to the border. When I asked where to leave the workshop suitcases, they had no info to offer. When I asked about my train to Toronto, I was told I’d have to call Amtrak. Then they gave me and a Japanese woman a free van ride to the US side of the border in Niagra Falls, NY. As we were getting in the van, one of the CBP people politely told me that in order to get into Canada, I’d need court records for my arrest when I was a young teenager.

    Flashback: I’m 13 years old, hanging out with a friend in suburbia. My friend has the idea to grab his remote control for his garage door, and see if it works on any other garage doors in the neighborhood. Wouldn’t you know it — it did! In the hour that we walked around his suburban ‘hood, we came across 5 garage doors that would open. Damn. On the last one, we hid behind a bush, and opened and closed and opened and closed the garage door to see what would happen. The people who lived there came out, scratched their heads, and went back inside. As we were walking home, the police stopped us, assuming we were the people wanting to break into someone’s garage. Oddly (naively), it never even occurred to us that anyone would think we were trying to steal anything.

    After meeting with a lawyer friend of my dad’s, he told me that after I did some community service, I should never tell anyone about this, since the record would be expunged.

    It turns out, however, that the record was not expunged. After all these decades, it’s the CBP that (politely) told me this. They also (politely) told me that in order to get into Canada, I’ll need the court records for this case, otherwise they’ll assume that the case is still open. Since I was never given any records (from my parents or anyone), and I have no idea how to get any court records, this may mean that I may never be welcome to Canada ever again.

    Scratch the WorldFuture 2012 conference in Toronto and the workshop at Vancouver Hack Space.
