1522 5 Simple steps to secure TT-RSS reader
secure tt-rss, tt-rss security 5 Simple steps to secure TT-RSS reader July 27, 2015 by Anand Leave a Comment secure-tt-rss-ft Share: share htpcBeginner We recently presented Tiny Tiny RSS to you as a great alternative to Google reader, which is one more way you can extend the functionality of your home server or your hosting space. Hopefully, you already exported your data from Google Reader. In this post, we will show you how to secure TT-RSS reader to prevent unauthorized access. Tiny Tiny RSS is an open source web-based news feed (RSS/Atom) reader and aggregator, designed to allow you to read news from any location, while feeling as close to a real desktop application as possible. As we previously explained, it makes an ideal candidate to replace Google Reader. While there are services like Feedly and Newsblur grabbing the crowd Google Reader, which some of you may prefer, there are a group of people who would like to run a RSS reader on their own server and keep things private. Assuming that you have already installed Tiny Tiny RSS on your alternative to Google reader or hosting space, we will now show you how to secure TT-RSS reader. Secure TT-RSS Reader One of the main reasons to move to an RSS aggregator like TT-RSS is maintaining your privacy. So if you do not secure TT-RSS reader well you are not only making your data available public but also making your system vulnerable to potential attacks. Choosing a strong username and password while setting your TT-RSS is the first basic thing that you can do to secure TT-RSS reader. Listed below are few more ways you can increase TT-RSS reader’s security. 1. Rename TT-RSS Folder One of the first lines of defense is to not use tt-rss in your URL to access your TT-RSS reader. To do this on your hosting account, use a folder name other than tt-rss while installing TT-RSS. On your Linux home server, edit /etc/tt-rss/apache.conf and change the first /tt-rss to something else. An example is shown below. TT-RSS Rename URL TT-RSS Rename URL After making the change, restart your TT-RSS and Apache to apply the changes: sudo service tt-rss restart sudo serivce apache2 reload Your TT-RSS reader is now available through the new URL (example: http://mydomain.com/myreader) only. Amazon Kindle Fire HDX 2. Enable SSL Accessing TT-RSS through http sends all information as unencrypted data. This could mean less privacy due to potential sniffing. The solution is to encrypt the data during transfer, which makes sniffing by hackers harder. To enable and enforce HTTPS access on Linux servers with Apache, install the following run-time libraries: sudo apt-get install libssl0.9.8 libpam0g openssl Restart your Apache server as shown above. You should now be able to access your TT-RSS reader with HTTPS. Note that you may have to have a SSL certificate generated. Refer to Apache documentation if you want to generate your own certificate. By default, the system will install self-signed certificates for you. These certificates are likely to raise warnings when you point your browser to the site. 3. Disable Single User Mode By default the single user mode is already disabled (in /etc/tt-rss/config.php). Enabling single user mode will also disable TT-RSS login system. Therefore, keep the single user mode disabled. Disable Single User Mode Disable Single User Mode A better way to make it a single user system is by limiting the number of registrations to 1 as described below. For whatever reason, you still want to enable single user mode, make sure you implement Apache Authentication method described below. 4. Self Registrations Self registrations allow a visitor to register themselves, which could reduce TT-RSS security. If your TT-RSS will be for personal use only, then you may want to disable user registration by setting “ENABLE_REGISTRATION” to “false”. TT-RSS Self Registrations TT-RSS Self Registrations To further secure TT-RSS Reader, uou may also want to change “REG_MAX_USERS” to “1” to make your account the only account on TT-RSS. asus n66uASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router asus n66u reviewsFind out why it is rated the best wireless router in its class. 5. Apache Authentication Last but not the least, enable Authentication. This is even more important if you have enabled “Single User Mode” describe above. Every time you access TT-RSS, you will be asked for a username and password as shown in the picture below: Secure TT-RSS Reader On your hosting account this equivalent to password protecting a directory, in this case the TT-RSS directory. To do this on your Ubuntu server, you will have to create a .htpasswd file. More information is available in Apache documentation. But the easiest way to achieve this is to use one of the htpasswd generators available online. After you enter the username and password two code blocks will be generated. Copy the contents of the .htpasswd code block and save it to /etc/apache2/.htpasswd_ttrss. Next, copy the contents of the .htaccess code block and add it to /etc/tt-rss/apache.conf as shown below: TT-RSS Apache Authentication TT-RSS Apache Authentication Save and exit. Restart both TT-RSS and Apache previous shown above. You should be prompted for a password every time you try to access TT-RSS. Some may think that this double authentication method is an extra inconvenience. But I would rather be safe than sorry. Go ahead, secure Tiny Tiny RSS Reader and enjoy reading articles on your private secure RSS Reader.

Love ‘em or hate ‘em, they’re a necessary evil of the digital age. The reality is we all end up with an alphabet soup of passwords spread over dozens of various sites and services across the internet. Whilst we might not always practice it, we all know the theory of creating a good password; uniqueness, randomness and length. The more of each, the better. Of course we frequently don’t do this because of all sorts of human factors such as convenience, memory or simple unawareness of the risks. Still, when it’s a case of individuals electing not to create secure passwords, they really only have themselves to blame. But what happens when the website won’t allow you to create a secure password? Or at least when they severely constrain your ability to create long, random, unique passwords? And what about when they don’t allow you to send it between your computer and their server securely? Even worse, what happens when our most “secure” institutions implement lazy password policies? Unfortunately, all of this is pretty rampant practice.

949 simple algorithms
Hi. This is a place to find information about some of the more fundamental algorithms used in computer science. This information is widely available on the net, but hopefully the way it's presented and discussed here will resonate with you. Most of these are things you wouldn't need to write yourself. Modern libraries and languages tend to have quality implementations for all of this. Nonetheless, I truly believe that understanding how things work is key to improving how we work. Enjoy.

884 jh_polykorg_clone
I have started to build a (slightly) updated version of the Korg PS-3200 synthesizer. The PS-3200 was the last of three fully polyphonic, semi-modular analogue synthesizers offered by Korg in the late 70's. (See Ben Ward's excellent Korg PS site for detailed information, including user manuals.) The concept of the PS-Synthesizers was different from other manufacturer's early polyphonic instruments. Instead of using a small number of voices and a clever keyboard assigning circuit, the "PolyKorgs" had a complete synthesizer circuit, hard wired to each key. That makes a total of 48 VCFs, 48 VCAs and 48 voltage controlled ADSRs even for the smallest of the range, the PS-3100. The largest of the range, PS-3300, even had 144 of these circuits. The sheer number of synthesizer circuits called for an extremly economic circuit design, and it's a joy to look at Korg's design ideas which led to building blocks that almost did the same as in the better known "classic" synthesizers. And after many years of engineering and reverse-engineering electronic music circuits, I have learned to look at odd solutions not as "substandard", but as a source of creativity an individual character. Here's a list of some highlights: Function Implementation Side effects Single-Transistor Waveform Converter creates triangle, saw, pulse and PWM from saw input, using one (!) transistor, one diode and two resistors per voice, plus two global control voltages Pulse height also changes with pulse width 5-Transistor-VCF (Korg-35) A Voltage controlled 2-pole (Sallen&Key) LPF built from 5 transistors rather high CV feedthru Single-Diode VC Resonance The dynamic resistance of a simple diode is used to alter the feedback gain of the VCF limited range of Q "Expand" function instead of VCF Envelope modulation depth Instead of scaling down the ADSR with a VCA, the a variable portion of the Envelope is just clipped with a single diode. It's so remarkably close to ordinary VCA function that apparently nobody takes notice. At least I have not read about it anywhere. At slow Atack times, the Envelope appears delayed at the VCF (no effect until th eclipping point is reached). Usefull for Brass sounds, and not easy to emulate with conventional synthesizers. Minimum parts count Voltage Controlled ADSR Three transistors, 1/2 of a LM324 and one CD4007 per voice. Plus some more involved control circuit, shared by several voices Transistors must be selected in 13-tuples, not just in pairs. ADSR detail (1): One-opamp control logic 1/4 LM324 is used as Flipflop, which is dynamically set by Gate-ON, dynamically reset by Gate-OFF, statically reset when the attack peak voltage is reached, and whose set/reset sensitivity is altered by a CV Very odd "Hold" function, depending on the "Attack"-value. But very useful in practise. ADSR detail (2): Single-Transistor, exponential slope VC-Decay Using a single transistor per voice for VC Attack and Release is remarkable already, even though the A and R slopes are linerar. But the Decay slope is exponential, and this is achieved with a single transistor and two resistors per voice! The Decay time range is rather limited. No ultra fast Decay, and no ultra slow Decay either. Single-Transistor VCA That's the "Korg standard" VCA, well known from other instruments like the MS-10.

865 Evolver.html
Just Beautiful! What an amazing instrument! The DSI Evolver has the signature "old school" timbre down pat as well as being able to provide digital timbres reminiscent of the Waldorf Q. There's certainly a "rougher" side available as well with all the feedback implementation and controled distortion. Being able to make PM type plucked and blown sounds is just icing on the cake. Dave Smith should be commended for a job well done. Just have a look at the Panel Layout to get a taste of what this beauty can dish out - the controls are pretty much laid out in the form of a signal path graphic. Be sure to visit Dave Smith's Website! Evolver Sound Examples There are a lot of demos of the Evolver on the web showcasing the gutsy harsh sounds of this beast so I decided to post demos of some of my own patches as examples of the "softer" more "vintage" side of the Evolver's timbre. I make no apologies for these unpolished recordings - these are merely sound samples ;) Resonant Plucked Pad This pad shows some of the rich resonant nature of the filter. Soft Lead This is a simple analog brass lead patch. FM Pad A fun patch with lots of motion made using my "Audio-rate Filter FM" programming tip below. Warm Pad A nice bland-vanilla pad ^_^ What can I say? I love pads... For more MP3 demos showing the full gamut of sounds the Evolver and Polyevolver are capable of, please visit the excellent website of Stefan Trippler! The Definitive Guide to Evolver This rather in-depth guide to the Evolver goes places and does things a mere manual can't. This labor-of-love was crafted by Anu Kirk and with his kind permission, I am offering this fantastic resource right here in PDF format! A much smaller version (400K) is here but it dosen't have internal hyperlinks. Programming Tips Here's a fun repository of programming tips for the Evolver in all its incarnations. Please email me if you would like to add some. Fingered Wave Sequence Submitted by Dave Bryce. This brilliant technique has to be heard to be believed! Plus, its one of those cool things unique to the Evolver! This particular tip is so full of detailed information that it gets its own page! Audio-rate Filter FM Submitted by James Maier. Use the "Audio Mod" parameter in the Filter section to frequency-modulate the cutoff with the analog oscillator. Add resonance until the filter is just on the edge of oscillation then mod the cutoff with just a little triangle LFO set at a very slow speed. Amazing moving chorusing pad and lead sounds can be made this way. Fatter Bass/Pad Sounds Submitted by Mike Peake. Set the same sound in both channels (detuned saws, for instance). With the filters at the 24dB setting, increasing resonance cuts the passband as on the Moog filters. Set Envelope 3 to minimum attack, maximum decay and release, and sustain to maximum. This "creates" an offset, a continuous "on" signal while the keys are gated. Modulate one filters' resonance up (just one), or of the overall resonance level is high, us it to modulate one filters' resonance to its minimum. You get the resonant character plus the size of the non-resonant filter. Use Tri and Sine waves on that side too. "Warmer" Sounds Submitted by James Maier. The Evolver can make many ultra-bright and buzzy sounds due to its extensive feedback and distortion stages but sometimes people miss the subtler side of the beast. For a warmer sound use little or no distortion, close the filter just a bit and turn off the feedback and delay lines. I've managed to get dead-on Prophet5 timbres this way. Adding "Punch" Submitted by Mike Peake. Set the envelopes to linear, and use a Mod to modulate AmpEnv All by itself (lin through log responses with positive and negative self-modulation). This is of course fun on the filter envelopes as well. More Vintage Character Submitted by Mike Peake. Oscillator Slop, set at 5, doesn't come close to the Moog and other old-timer movement, so add slight (1 or 2) LFO to pitch modulations, with individual LFOs per oscillator, and a touch of LFO to LFO rate modulation. A tad of Envelope 3 to pitch helps as well. Don't miss out on the 12dB filter setting Submitted by Mike Peake. The 24dB setting has much more resonance, but the 12dB setting can sound nice and plucky, and do nice slightly fuzzy pads etc. DSI Evolver Waveshape Charts Below are charts I've assembled of the digital waveforms and their spectra as currently used in the DSI Evolver synthesizers. Originally these waves were unique to the SCI ProphetVS vector synth. I find these waveform/spectra graphics really usefull when programming sounds - maybe you will as well. Pay special attention to the spectra as this info is sometimes much more useful than waveshape in determining actual timbre - even before you hear what the waveform sounds like. These are designed to be downloaded (right-click & "save target as"), and printed at 300dpi on 8.5" x 11" pages - don't resize these images before printing or you will lose useful detail. Use them as a handy refrence. This information was cobbled together from various scattered sources (with very special thanks to Achim Gratz!). Any errors or omissions are my own. ^_^ HAVE FUN!!! Page 1 Page 2 Page 3 Page 4 As far as the origin of these waves is concerned, one of the original VS engineers, Chris Meyer, said: "The original waves for the VS were created three ways - extracting single-cycles from sampled sounds, using a custom additive synthesis program, and using a program Josh (Josh Jeffe, another VS engineer) slapped together called "Hacker" where you could draw the waveshape. These were fed straight from the computer through the filter and VCA of a Pro-One to figure out what they might sound like in a patch. And by the way, no PPG waveforms appear inside the VS - we had access to them, but in the end our consciences got the better of us. We did steal some waveforms from the Korg DW6000, but only by looking at the harmonic drawings on the front panel and trying to imitate them in our additive synthesis program." Modulation Matrix "Cheat Sheet" This chart shows all the modulation routing available on the Evolver. This same info is available in the manual but this can be printed on a single sheet of paper as a handy refrence! Evolver Wallpaper These I created just for fun and desktop "beautification" ;) 1280 X 1024 1024 X 768 800 X 600

766 [WS001] Circuit-Bending – Initiation « Gasol
Introduction Le Circuit-Bending ou Circuitage dĂ©signe l’activitĂ© qui consiste Ă  volontairement court-circuiter un appareil Ă©lectronique (gĂ©nĂ©ralement sonore) afin de provoquer des comportements inattendus pour le dĂ©tourner de son usage d’origine. Par exemple, un jouet sonore pour enfant ou une console de jeu gĂ©nĂ©reront des sons ou des images plus ou moins alĂ©atoires et imprĂ©visibles. Ce terme Ă  Ă©tĂ© introduit par Reed Ghazala dans les annĂ©e 60 lorsqu’il court-circuita accidentellement l’un de ses instruments. Mais des mĂ©thodes similaires ont Ă©tĂ© utilisĂ©es auparavant par d’autres musiciens et ingĂ©nieurs. Cette activitĂ© peut ĂȘtre assimilĂ©e Ă  une certaine forme d’art, de part le dĂ©tournement, l’appropriation et la personnalisation de ces appareils ainsi que leurs usages lors de performances audiovisuelles. C’est l’art du court-circuit. On rencontrera souvent les termes Circuit-Bender ou Bender pour dĂ©signer la personne qui effectue ces modifications et on parlera de Bends pour toutes modifications apportĂ©es Ă  l’appareil. Attention: Ne jamais tenter ces manipulations sur des appareils alimentĂ©s par une tension supĂ©rieure Ă  12V, risque d’électrocution. Ne pas torturer des appareils trop onĂ©reux ou auxquels on tient, en effet il existe un haut risque de casse irrĂ©versible qui transformera le jouet en un joli presse papier. Un peu de thĂ©orie Le Circuitage ne demande pas de grandes connaissances en Ă©lectronique, mais quelques bases sont nĂ©cessaires Ă  l’apprĂ©hension de cette activitĂ©. Notamment la reconnaissance des divers composants Ă©lectroniques qui seront utilisĂ©s ou court-circuitĂ©s. RĂ©sistances La rĂ©sistance est surement le composant le plus rĂ©pandu. Sa principale caractĂ©ristique est d’opposer une plus ou moins grande rĂ©sistance Ă  la circulation du courant Ă©lectrique. Sa valeur (mesurĂ©e en ohms) peut ĂȘtre dĂ©terminĂ©e par un code couleur ou lue sur le boĂźtier des composants les plus rĂ©cents. PotentiomĂštres Un potentiomĂštre n’est autre qu’une rĂ©sistance ajustable. Il possĂšde 3 pattes ainsi qu’un systĂšme mĂ©canique permettant la variation de la rĂ©sistance. Photo-rĂ©sistances Une photo-rĂ©sistance est Ă©galement une rĂ©sistance dont la valeur varie en fonction de l’intensitĂ© lumineuse. On peut Ă©galement le nommer rĂ©sistance photo-dĂ©pendante (light-dependent resistor (LDR)) ou photoconducteur. Condensateurs Un condensateur est un composant Ă©lectronique ou Ă©lectrique Ă©lĂ©mentaire qui a pour propriĂ©tĂ© principale de pouvoir stocker des charges Ă©lectriques opposĂ©es sur ses armatures. Il est utilisĂ© principalement pour stabiliser une alimentation Ă©lectrique, traiter des signaux pĂ©riodiques, sĂ©parer le courant alternatif du courant continu, stocker de l’énergie. Diodes La diode est principalement utilisĂ©e comme convertisseur de courant alternatif vers du courant continu ou comme multiplicateur ou rĂ©gulateur de tension. C’est un composant polarisĂ©, ce qui signifie que le sens de branchement a une importance sur le fonctionnement du montage. Diodes Electro-Luminescentes (DEL / LED) La LED possĂšde la particularitĂ© de gĂ©nĂ©rer de la lumiĂšre lorsqu’elle est parcourue par un courant. De la mĂȘme maniĂšre que la diode, ce composant est polarisĂ©. Transistors Le transistor est le composant actif utilisĂ© principalement comme interrupteur commandĂ© ou pour l’amplification, mais aussi pour stabiliser une tension ou moduler un signal. Circuits intĂ©grĂ©s Le circuit intĂ©grĂ© (CI), aussi appelĂ© puce Ă©lectronique, est un composant Ă©lectronique reproduisant une ou plusieurs fonctions Ă©lectroniques plus ou moins complexes, intĂ©grant souvent plusieurs types de composants Ă©lectroniques de base dans un volume rĂ©duit, rendant le circuit facile Ă  mettre en Ɠuvre. Il existe une trĂšs grande variĂ©tĂ© de ces composants divisĂ©s en deux grandes catĂ©gories : analogique et numĂ©rique. Interrupteurs Un interrupteur est un dispositif permettant d’interrompre ou d’autoriser le passage d’un flux. Boutons poussoirs Le bouton poussoir est une touche tactile qui permet de faire une liaison Ă©lectrique momentanĂ©e le temps que l’on appuie dessus ou, sur certains modĂšles inversĂ©s, d’ouvrir temporairement le contact Ă©lectrique. Connecteurs Jack Format de connecteur mĂąle et femelle gĂ©nĂ©ralement utilisĂ© pour les connexions audio de types casques et micros. Le mini Jack fait 3,5 mm de diamĂštre, le jack normal fait 6,35 mm. MatĂ©riel et compĂ©tences Pour mener Ă  bien ces projets et en plus de certains composants citĂ©s ci-dessus, il faudra ĂȘtre Ă©quipĂ© du matĂ©riel basique (tournevis, fer Ă  souder, Ă©tain, pompe Ă  dessouder, cĂąblage, pinces coupantes, pinces croco, perceuse, dremel 
) De plus, il faudra un minimum de compĂ©tences en soudage, mais tout le monde se souvient des cours de technologies au collĂšge et dans tous les cas, ces compĂ©tences s’acquiĂšrent vite aprĂšs quelques essais. Il faudra simplement veiller Ă  ne pas dĂ©poser la panne du fer trop longtemps sur un composant pour ne pas l’endommager et ne pas faire baver l’étain au risque de crĂ©er un court-circuit non souhaitĂ©. Il faudra Ă©galement s’armer de patience, c’est la qualitĂ© premiĂšre et la plus haute compĂ©tence d’un Bender. En effet, un jouet nĂ©cessite gĂ©nĂ©ralement entre 4 Ă  12h pour ĂȘtre modifiĂ© (dont les 3/4 de ce temps sont consacrĂ©s Ă  la recherche des Bends). Avec l’expĂ©rience ce temps sera considĂ©rablement rĂ©duit. Beaucoup de pratique Victimes potentielles Pour dĂ©buter, l’idĂ©al est de s’attaquer Ă  des appareils peu couteux tels que des jouets sonores rĂ©cupĂ©rĂ©s dans votre cave ou lors de vide-greniers. Les plus rĂ©putĂ©s Ă©tant les jouets vintages du type DictĂ©e Magique et dĂ©rivĂ©s (Speak&Spell/Math/Learn), les insupportables Furby, les petits synthĂ©tiseurs type Casio SK-1 
 Tout ce qui possĂšde un haut-parleur, fonctionne sur piles ou en dessous de 12V. Plus particuliĂšrement les appareils fabriquĂ©s durant les annĂ©es 80/90 qui ne sont pas encore Ă©quipĂ©s de composants Ă©lectroniques sophistiquĂ©s ou de circuits entiĂšrement numĂ©riques. Les constructeurs les plus connus sont: Texas Instruments, Casio, Vtech, Coleco, Creatoy. Il est Ă©videmment possible d’élargir les domaines de recherches Ă  des appareils plus Ă©laborĂ©s mais gare Ă  l’irrĂ©versible court-circuit meurtrier qui mettra dĂ©finitivement la machine hors-service. Recherche Il faut tout d’abord dĂ©sosser votre cible pour mettre Ă  nu le circuit Ă©lectronique. Ensuite, on allume le jouet pour lui faire Ă©mettre un son et on test simplement sa rĂ©activitĂ© en posant plusieurs doigts simultanĂ©ment sur diffĂ©rents endroits du circuit. GĂ©nĂ©ralement, un effet de « pitch » se fait entendre (baisse/augmentation de la tonalitĂ©), on comprend alors que la machine est sensible au Circuitage et les choses sĂ©rieuses peuvent donc commencer (toutes les machines ne sont pas forcement sensibles au toucher, mais c’est une bonne technique d’approche). Afin de ne pas avoir Ă  mĂ©moriser tous les endroits sensibles, l’idĂ©al est de prendre une photo du circuit, de la transferer sur un ordinateur et ainsi noter pas Ă  pas Ă  l’aide d’un logiciel de dessin type MSPaint ou Photoshop tous les Bends dĂ©couverts. Certains les notent directement sur le circuit Ă  l’aide d’un stylo ou d’un feutre, mais l’encre contenant gĂ©nĂ©ralement du carbone et le carbone Ă©tant conducteur, il existe un risque de court-circuit non dĂ©sirĂ© dont on pourra difficilement se dĂ©faire. La premiĂšre et la plus simple des modifications Ă  apporter Ă  son appareil est le raccordement Ă  un ampli ou une console de mixage. Il sera alors possible d’enregistrer les sons de la machine ou de l’utiliser lors de performances live. Pour ce faire, on repĂšre gĂ©nĂ©ralement le haut-parleur et on le remplace ou on installe en parallĂšle un connecteur Jack. Dans le second cas, l’ajout d’un interrupteur pourra servir Ă  basculer entre la sortie audio ou le haut-parleur. On peut maintenant commencer Ă  parcourir mĂ©thodiquement ou au hasard le circuit Ă  l’aide d’un testeur. Le plus simple est d’utiliser des pinces croco que l’on raccordera Ă  deux petits tournevis d’horloger. On place la pointe du premier tournevis qui restera stationnaire sur un point du circuit et avec le second on parcourt diffĂ©rents autres points en Ă©coutant les changements de sons intĂ©ressants que l’on note au fur et Ă  mesure sur notre photo. On poursuit ensuite en dĂ©plaçant le premier tournevis sur un autre point et en recommençant notre parcours avec le second. On rĂ©pĂšte cette procĂ©dure jusqu’à ce que la totalitĂ© du circuit ait Ă©tĂ© parcouru ou lorsque nous estimons avoir trouvĂ© toutes les modifications souhaitĂ©es. Les Bends les plus courants sont gĂ©nĂ©ralement: la sortie audio permettant l’amplification, le volume, l’overdrive/distortion, les glitches, les boucles, le bouton reset. Dans certains cas, les Bends ne sont pas compatibles entre-eux. La machine plantera irrĂ©mĂ©diablement dĂšs lors qu’on activera plusieurs Bends simultanĂ©ment. On peut alors dĂ©cider de continuer la quĂȘte des modifications compatibles ou bien Ă©viter d’en activer plusieurs Ă  la fois. CĂąblage et placement des composants La prochaine Ă©tape est le raccordement des diffĂ©rents points du circuit trouvĂ©s prĂ©cĂ©demment. On les relie entre eux en soudant un fin cĂąble de cuivre sur chaque point. On placera ensuite, par exemple, un interrupteur entre deux de ces cĂąbles allant de paires, de maniĂšre Ă  (dĂ©s)activer notre court-circuit. Il est aussi possible dans certains cas de remplacer ou coupler l’interrupteur Ă  un potentiomĂštre ou une photo-rĂ©sistance qui appliquera une plus ou moins grande rĂ©sistance au passage du courant, attĂ©nuant ou accentuant ainsi l’effet du court-circuit (trĂšs utile pour les effets de pitch/volume/overdrive). Il est prĂ©fĂ©rable de ne pas souder le composant avant de l’avoir montĂ© sur le chĂąssis de la machine, de maniĂšre Ă  ne pas le dessouder par inadvertance lors de son placement. Utile aussi pour connaitre la bonne longueur des cĂąbles et leur cheminement et ainsi Ă©viter les surplus qui empĂȘcheraient la fermeture du boitier. Pour percer le chĂąssis, on utilisera une petite perceuse ou un Dremel. Le positionnement des composants est libre mais attention Ă  choisir un emplacement qui ne gĂȘnera ni la fermeture, ni l’ergonomie du boitier. En effet, un composant mal placĂ© et difficilement accessible pourrait compromettre la spontanĂ©itĂ© de la performance. Afin de ne pas trop endommager le chĂąssis, il est aussi possible de raccorder tous les composants sur un boitier externe qui servira de contrĂŽleur. Dans ce cas, l’utilisation d’un cĂąble nappe tel que l’on trouve dans un ordinateur peut ĂȘtre trĂšs pratique pour ne pas avoir des dizaines de fils qui sortent du chĂąssis (un cĂąble SCSI est parfait pour ce type de montage).

722 Making AJAX Applications Crawlable - Google Code
If you're running an AJAX application with content that you'd like to appear in search results, we have a new process that, when implemented, can help Google (and potentially other search engines) crawl and index your content. Historically, AJAX applications have been difficult for search engines to process because AJAX content is produced dynamically by the browser and thus not visible to crawlers. While there are existing methods for dealing with this problem, they involve regular manual maintenance to keep the content up-to-date. Learn more Learn why search engines don't see the content you see and what needs to happen to fix this. Getting started guide Get started in making your AJAX application visible to search engines. If you are in a hurry, you can start here, but AJAX crawling is a complex topic, so we recommend reading all the documentation. Creating HTML snapshots Learn more about creating HTML snapshots, and which technique might be best suited for your application. Frequently asked questions Having trouble?

Since this post got quite popular I decided to incorporate some of the excellent suggestions posted in the comments, so this list now has more than 40 books in it. [UPDATED: 2010-10-12] Learning a new programming language always is fun and there are many great books legally available for free online. Here’s a selection of 30 of them: Lisp/Scheme: How to Desing Programs Interpreting Lisp (PDF, suggested by Gary Knott) Let Over Lambda On Lisp Practical Common Lisp Programming in Emacs Lisp Programming Languages. Application and Interpretation (suggested by Alex Ott) Structure and Interpretation of Computer Programs Teach Yourself Scheme in Fixnum Days Visual LISP Developer’s Bible (suggested by “skatterbrainz”) Ruby: Data Structures and Algorithms with Object-Oriented Design Patterns in Ruby Learn to Program MacRuby: The Definitive Guide Mr. Neighborly’s Humble Little Ruby Book (suggested by @tundal45) Programming Ruby Read Ruby 1.9 Ruby Best Practices Ruby on Rails Tutorial Book (suggested by @tundal45) Javascript: Building iPhone Apps with HTML, CSS, and JavaScript Eloquent Javascript jQuery Fundamentals Mastering Node Haskell: Learn You a Haskell for Great Good Real World Haskell Erlang: Concurrent Programming in Erlang Learn You Some Erlang for Great Good Python: Dive into Python How to Think Like a Computer Scientist – Learning with Python Smalltalk: Dynamic Web Development with Seaside Pharo by Example (based on the next book in this list, suggested by Anonymous) Squeak by Example Misc: Algorithms The Art of Assembly Language Beginning Perl Building Accessible Websites (suggested by Joe Clark) The C Book C# Yellow Book (suggested by Joe Wyatt) Compiler Construction Dive Into HTML 5 (suggested by @til) Higher-Order Perl The Implementation of Functional Programming Languages (suggested by “Def”) An Introduction to R Learn Prolog Now! Objective-C 2.0 Essentials Programming Scala Of course there are many more free programming eBooks, but this list consists of the ones I read or want(ed) to read. This is far from comprehensive and languages that are completely missing are mostly left out on purpose (e.g. PHP, C++, Java). I’m sure somebody else made a list for them somewhere.

484 Why did so many successful entrepreneurs and startups come out of PayPal? Answered by Insiders
Why did so many successful entrepreneurs and startups come out of PayPal? I long have been fascinated by the extraordinary achievement from the ex-Paypal team and wonder about the reasons behind their success. In the past, mass media tried to answer this question several times but still couldn’t give us a clear answer. I once asked David Sacks the same question during an event in Los Angeles. He told me the secret is that Paypal has built a “scrappy” culture. No matter what problems they faced, they would find a way to solve them. I kind of got the idea, but was still confused about the execution details. So when I saw some of the past Paypal employees answering this question on Quora, I was super excited! After all, they should be the only ones who can tell people the inside stories. Below are some highlights of their answers. *If you want to check out the sources or leave your comments, please go to here and here. On Talent Management “Peter and Max assembled an unusual critical mass of entrepreneurial talent, primarily due to their ability to recognize young people with extraordinary ability (the median age of *execs* on the S1 filing was 30). But the poor economy allowed us to close an abnormal number of offers, as virtually nobody other than eBay and (in part) google was hiring in 2000-02.” (by Keith Rabois, former Executive Vice President of Paypal) “Extreme Focus (driven by Peter): Peter required that everyone be tasked with exactly one priority. He would refuse to discuss virtually anything else with you except what was currently assigned as your #1 initiative. Even our annual review forms in 2001 required each employee to identify their single most valuable contribution to the company.” (by Keith Rabois, former Executive Vice President of Paypal) “Dedication to individual accomplishment: Teams were almost considered socialist institutions. Most great innovations at PayPal were driven by one person who then conscripted others to support, adopt, implement the new idea. If you identified the 8-12 most critical innovations at PayPal (or perhaps even the most important 25), almost every one had a single person inspire it (and often it drive it to implementation). As a result, David enforced an anti-meeting culture where any meeting that included more than 3-4 people was deemed suspect and subject to immediate adjournment if he gauged it inefficient. Our annual review forms in 2002 included a direction to rate the employee on “avoids imposing on others’ time, e.g. scheduling unnecessary meetings.” (by Keith Rabois, former Executive Vice President of Paypal) “Refusal to accept constraints, external or internal:We were expected to pursue our #1 priority with extreme dispatch (NOW) and vigor. To borrow an apt phrase, employees were expected to “come to work every day willing to be fired, to circumvent any order aimed at stopping your dream.” Jeremy Stoppelman has relayed elsewhere the story about an email he sent around criticizing management that he expected to get him fired and instead got him promoted. Peter did not accept no for answer: If you couldn’t solve the problem, someone else would be soon assigned to do it.” (by Keith Rabois, former Executive Vice President of Paypal) “Driven problem solvers: PayPal had a strong bias toward hiring (and promoting / encouraging, as Keith mentions) smart, driven problem solvers, rather than subject matter experts. Very few of the top performers at the company had any prior experience with payments, and many of the best employees had little or no prior background building Internet products. I worked on the fraud analytics team at PayPal, and most of our best people had never before done anything related to fraud detection. If he’d approached things “traditionally”, Max would have gone out and hired people who had been building logistic regression models for banks for 20 years but never innovated, and fraud losses would likely have swallowed the company.” (by Mike Greenfield, former Sr. Fraud R&D Scientist of Paypal) “Self-sufficiency – individuals and small teams were given fairly complex objectives and expected to figure out how to achieve them on their own. If you needed to integrate with an outside vendor, you picked up the phone yourself and called; you didn’t wait for a BD person to become available. You did (the first version of) mockups and wireframes yourself; you didn’t wait for a designer to become available. You wrote (the first draft of) site copy yourself; you didn’t wait for a content writer.” (by Yee Lee, former Product & BU GM of Paypal) On Culture & Ideology “Extreme bias towards action – early PayPal was simply a really *productive* workplace. This was partly driven by the culture of self-sufficiency. PayPal is and was, after all, a web service; and the company managed to ship prodigious amounts of relatively high-quality web software for a lot of years in a row early on. Yes, we had the usual politics between functional groups, but either individual heroes or small, high-trust teams more often than not found ways to deliver projects on-time.” (by Yee Lee, former Product & BU GM of Paypal) “Willingness to try – even in a data-driven culture, you’ll always run in to folks who either don’t believe you have collected the right supporting data for a given decision or who just aren’t comfortable when data contradicts their gut feeling. In many companies, those individuals would be the death of decision-making. At PayPal, I felt like you could almost always get someone to give it a *try* and then let performance data tell us whether to maintain the decision or rollback.” (by Yee Lee, former Product & BU GM of Paypal) “Data-driven decision making – PayPal was filled with smart, opinionated people who were often at logger-heads. The way to win arguments was to bring data to bear. So you never started a sentence like this “I feel like it’s a problem that our users can’t do X”, instead you’d do your homework first and then come to the table with “35% of our [insert some key metric here] are caused by the lack of X functionality
” (by Yee Lee, former Product & BU GM of Paypal) “Radical transparency on metrics: All employees were expected to be facile with the metrics driving the business. Otherwise, how could one expect each employee to make rational calculations and decisions on their own every day? To enforce this norm, almost every all-hands meeting consisted of distributing a printed Excel spreadsheet to the assembled masses and Peter conducting a line by line review of our performance (this is only a modest exaggeration).” (by Keith Rabois, former Executive Vice President of Paypal) “Vigorous debate, often via email: Almost every important issue had champions and critics. These were normally resolved not by official edict but by a vigorous debate that could be very intense. Being able to articulate and defend a strategy or product in a succinct, compelling manner with empirical analysis and withstand a withering critique was a key attribute of almost every key contributor. I still recall the trepidation I confronted when I was informed that I needed to defend the feasibility of my favorite “baby” to Max for the first time.” (by Keith Rabois, former Executive Vice President of Paypal) “Extreme Pressure – PayPal was a very difficult business with many major issues to solve. We were able to see our colleagues work under extreme pressure and hence we learned who we could rely on and trust.” (by Keith Rabois, former Executive Vice President of Paypal)

Parfois, il s'agit simplement d'une application utilisant le fichier en question (dans le cas d'un document Word ou Photoshop, par exemple), mais il peut aussi s'agir d'un processus moins Ă©vident Ă  dĂ©tecter. Unlocker propose une interface dans la lignĂ©e de Who Lock Me, mais des possibilitĂ©s plus Ă©tendues. DĂ©tail apprĂ©ciable pour commencer : il rĂ©side dans la barre de notification et se lance automatiquement dĂšs l'affichage du message d'erreur (il est Ă©galement possible de l'ouvrir depuis le menu contextuel) Vous pouvez tuer le processus mais aussi « dĂ©vĂ©rouiller » le fichier sans fermer l'application lorsque c'est possible. Unlocker ne se limite d'ailleurs pas Ă  la suppression d'un fichier en cours d'utilisation puisqu'il permet Ă©galement de le dĂ©placer ou renommer. Un mode ligne de commande est disponible en plus de l'interface graphique.
