Back¦Track-fr sécurité réseau & intrusion 11 ways to fit into a free software project Dec 23, 2013 GMT Bruce Byfield Many technical writers believe that all they need are writing skills. Consequently, my contracts usually began with a period of proving to developers that I could handle the technical details as well. Talking about Linux worked wonders, but it could still be an uphill battle. Later, I found journalism required much the same process of overcoming a closed community's reaction to an outsider long enough to gain useful information. With these experience, I was surprised the other week to come across several complaints that the free software community was hostile to outsiders. Others, of course, don't have those advantages. All the same, based on my experience and that of veteran contributors, I believe that outsiders have a better chance of being accepted by a project if they follow a few simple practices in the early days of their involvement. 11. 10. 9. 8. 7. 6.Ask for feedback: Your contributions will probably get feedback without any need to ask. 5. 3. 2.
Build Your Own Internet with Mobile Mesh Networking After an earthquake crippled Haiti in 2010, killing and injuring hundreds of thousands and destroying the country’s communication networks, Paul Gardner-Stephen found himself thinking about all the cell phones that had instantly become useless. With cell towers out of commission across the country, they would be unable to operate. “If the software on the phones was right,” he says, “they would keep working for at least localized communication, handset to handset.” Gardner-Stephen, a research fellow at Flinders University in Adelaide, Australia, now leads a project that enables Android phones to do just that. This approach, known as mesh networking, is not a new idea (see “Automatic Networks”). Some communities in Washington, Brooklyn, and Detroit already have Wi-Fi-based mesh networks built on Commotion’s technology. “You could have someone taking pictures and video at a protest and sharing them immediately to the mesh,” he says.
frpn.free Si vous voulez augmentez la portée de votre connexion WIFI, ou si vous avez des problèmes de connexion WIFI (absence de signal, déconnexions fréquentes,...), alors cette page est pour vous. Réflecteur parabolique pour antenne wifi omnidirectionnelle Gain : entre +8 et +14dB Valeurs mesurées par DD-WRT configuré en mode Client avec un AP situé dans la pièce voisine et équipé d'antennes omni : Antenne d'origine (données constructeur 2dbi) : Signal : -65 Noise : -104 SNR : 39 Qualité du signal : 35% Antenne bricolée : Signal : -51 Noise : -104 SNR : 53 Qualité du signal : 53% Note : Si la valeur maximale relevée de 14dB semble très élevée, un gain de 6 à 8dB de gain nominal est facilement atteignable. Principe : Un peu de culture : ici. But : construire une antenne directive afin de limiter l'éparpillement des ondes wifi et améliorer le signal. Matériel nécessaire : 1/ Tracer une parabole sur le papier quadrillé (valeurs en mm) : 2/ Placer le foyer de la parabole : 3/ Découper la parabole.
Facedetect: Free face detection software Marco Fioretti shows you how to download and get started with facedetect, free face detection and recognition software. Automatic, face detection and recognition software is very cool technology. However, it can also be a Big Brother-style surveillance nightmare if turned on CCTV cameras 24/7 or a recurring annoyance whenever someone on Facebook tags you in photographs you didn't even know existed. Such momentous issues are outside the scope of this column, of course. I have other reasons to talk about face detection here. Let's play with facedetect Facedetect is a small Python command line utility that uses the Open Source Computer Vision Library (OpenCV) to recognize which regions of a digital photograph correspond to human faces. To make facedetect available to all users of your Linux system, download the zip archive from its home page, unpack it, and copy the facedetect Python file into the /usr/local/bin directory. Please look closely at Figure A. Figure A Figure B Figure C
The Serval Project Wiki - The Serval Project Wiki Amplifier ou booster le réseau WIFI à la maison Les problèmes de connexion au réseau Wifi du domicile, par exemple à partir d’un ordinateur fixe ou portable situé dans une pièce plus ou moins éloignée du point d’accès (box) sont généralement dus à la faiblesse du signal en réception. Ils sont très faciles à résoudre. Il suffit simplement d’augmenter le ‘gain’ de votre équipement, ce qui augmentera la portée de réception. Tour d’horizon des matériels existants : 1) La clé USB Wi-Fi avec antenne démontable: Elle se présente comme une clé USB classique avec une antenne démontable à son extrémité. Avantages : Simplicité (facile à installer et démonter), Pas de câble, donc pas de perte de gain Mobile (peut-être utiliser partout chez soi, voiture, gares et aéroports, bateau au port, camping, etc…) Économique (environ 50 € TTC) Pour en savoir + sur la clé USB Wi-Fi avec antenne démontable, cliquez ici Son prix : environ 90 € TTC auquel il faut rajouter le prix de la clé USB avec antenne démontable Attention!
