Flying chair

You have all heard that story about the guy who attached weather balloons to his lawn chair:
(1982, California) Larry Walters of Los Angeles is one of the few to contend for the Darwin Awards and live to tell the tale. "I have fulfilled my 20-year dream," said Walters, a former truck driver for a company that makes TV commercials. "I'm staying on the ground. I've proved the thing works."

Larry's boyhood dream was to fly. But fates conspired to keep him from his dream. He joined the Air Force, but his poor eyesight disqualified him from the job of pilot. After he was discharged from the military, he sat in his backyard watching jets fly overhead.

He hatched his weather balloon scheme while sitting outside in his "extremely comfortable" Sears lawnchair. He purchased 45 weather balloons from an Army-Navy surplus store, tied them to his tethered lawnchair dubbed the Inspiration I, and filled the 4' diameter balloons with helium. Then he strapped himself into his lawnchair with some sandwiches, Miller Lite, and a pellet gun. He figured he would pop a few of the many balloons when it was time to descend.

Larry's plan was to sever the anchor and lazily float up to a height of about 30 feet above his back yard, where he would enjoy a few hours of flight before coming back down. But things didn't work out quite as Larry planned.

When his friends cut the cord anchoring the lawnchair to his Jeep, he did not float lazily up to 30 feet. Instead, he streaked into the LA sky as if shot from a cannon, pulled by the lift of 42 helium balloons holding 33 cubic feet of helium each. He didn't level off at 100 feet, nor did he level off at 1000 feet. After climbing and climbing, he leveled off at 16,000 feet.

At that height he felt he couldn't risk shooting any of the balloons, lest he unbalance the load and really find himself in trouble. So he stayed there, drifting cold and frightened with his beer and sandwiches, for more than 14 hours. He crossed the primary approach corridor of LAX, where Trans World Airlines and Delta Airlines pilots radioed in reports of the strange sight.

Eventually he gathered the nerve to shoot a few balloons, and slowly descended. The hanging tethers tangled and caught in a power line, blacking out a Long Beach neighborhood for 20 minutes. Larry climbed to safety, where he was arrested by waiting members of the LAPD. As he was led away in handcuffs, a reporter dispatched to cover the daring rescue asked him why he had done it. Larry replied nonchalantly, "A man can't just sit around."

The Federal Aviation Administration was not amused. Safety Inspector Neal Savoy said, "We know he broke some part of the Federal Aviation Act, and as soon as we decide which part it is, a charge will be filed."


Well some other lunatic did another attempt. He even has instruments on board, such as an altimeter. Keep trying to kill yourself guys.

Beziers - Pezenas - Coastline Flight

First flight over the Mediterraneans coast, and first Cessna 152 flight in 3 years. As always, Cessna 152 is tiny, very reactive and fun to fly. Almost 20 kts of wind so we were bounced around the sky (la Tramontane).

Bummer, my Casio Exilim S600 doesn't want to power up. I had to take pictures with my Treo 650.





Arrival in Pezenas. Dirt strip on a hill. Updrafts, downdrafts, 15kts direct cross wind. That was a real challenge but made it safe enough.



Flight over the coast line and over the Cap d'Agde. Look close, you will see naked people :-)





Partagas Short



(ceci est une note personnelle de ma dégustation d'un cigare, pour que je puisse m'y référer dans le futur. Cette note est strictement privée. Si vous la lisez, c'est sous votre propre responsabilité. Interdiction formelle de lire cette note si vous avez moins de 18 ans. Ne fumez pas le cigare. Fumer tue. Fumer donne mauvaise haleine. Fumer coûte une fortune à la sécu. Fumer le cigare donne l'air con, parvenu et nouveau riche.)

Evaluation générale: Bon. Plus long à fumer que sa taille laisse paraître (environ 45 minutes)

Lieu: Devant mon bureau. Il fait beau et 25°C. Que demande le peuple
Activité: Browsé Facebook
Accompagnement: Eau Quézac
Musique: Mix by LazyB

Général: un peu sec (OK, c'est ma faute...). belle cape. Pas trop d'arômes. Tirage un peu serré.

Dégustation:
1er tiers: fumée basique, on a vraiment l'impression que c'est de la fumée, c'est tout.
2ème tiers: Fumée épaisse, plaisante. Arômes de poivre, café . Y'a bon !
3ème tiers: Toujours agréable. Puissant pour sa taille. Stone.

Conclusion: a refaire. Je pensais qu'il serait un peu plus rapide à fumer (genre 20-30 minutes), donc ce n'est pas un cigare pour une "petite pause" comme je le pensais.

iPhone - The Final Attack

Des progrès sur le déverrouillage de l'iPhone

Visiblement le déverrouillages de l'iPhone est plus difficile que prévu, à cause de la signature numérique du code d'Apple.

Selon les nouvelles sur le iPhone Dev Wiki, ils ont toutefois réussi à enregistrer des iPhones sans contrat sur les réseaux virtuels qui portent les même "Network IDs" que le réseau ATT. Ca approche...

La course pour déverrouiller l'iPhone à commencé !


Les hackers sont à pied d'oeuvre. On peut suivre leur progrès sur le iPhone Dev Wiki.

Comme le iPhone utilise une SIM amovible, comme la plupart des téléphones portables, c'est un bon signe. Cela veut dire que le bloquage est au niveau du firmware, qui devrait être crackable.

Pour hacker le iPhone, il faut commencer par contourner le processus d'activation, mis en place par Apple. En effet, contrairement à la plupart des téléphones qui ne s'activent pas, celui-ci s'active, en même temps que l'activation de la ligne téléphonique mobile. Cet activation à lieu à travers iTunes. Sans cette activation, le téléphone ne marche pas - ni les autres fonctionnalités par ailleurs (appareil photo, iPod, etc.).

Ensuite, il s'agit de déverrouiller la protection autour de la carte SIM, comme pour les autres téléphones mobiles.

Les progrès semblent bon (toujours si on regarde ce qui se passe sur iPhone Dev Wiki) et certains spéculateurs pensent que l'iPhone serra déverrouillé avant mardi 3 juillet.
