Write plugins for XBMC XBMC includes support for writing Add-Ons written in Python. Plugins, unlike scripts, do not generally provide new functionality to XBMC, instead they provide an easy way to present content listings in XBMC through the native GUI interface. Content is usually online audio and video streams like YouTube, Vimeo or podcasts, or pictures from websites such as Flickr or Picasa. Please feel free to add samples of simple plugin functions. For end-user instruction on how to install XBMC plugins please see HOW-TO install and use plugins in XBMC. Note! Helpful tools: There's also lots of streaming sources available for building plugins: Before you begin, search the XBMC forum for the name of the plugin you are planning on creating. Right click on the file 'Default.py' and select 'Edit with IDLE'. This is just to familiarise yourself with the layout of the plugin template. Remember – it's all about the Tabs. Python is just like you and I, it has the ability to use information from other sources. for ?
quora Self-oscillating circuit for 5V power supply - UK Vintage Radio Repair and Restoration Discussion Forum I'm trying to make a circuit using the components of a CFL (HV transistors, ferrite core, HV diodes, HV capacitors, etc) in order to obtain a 5V source to supply a TTL-made timer for a microwave oven. All circuit I have checked use two ferrite cores. I think it is posible to do it using just one core. I need some help with the cicuit configuration (for the self oscilating circuit) and how many turns (approx.) should I coil in the ferrite core. The 5V circuit will demand 500mA. I want to rectify the 110 V AC line supply and using one of the capacitor of the CFL, obtain 150 V CD (non-regulated), and then the self-oscilating circuit with one independent secondary to obtain 5V using a single diode and a small capacitor. It is now working with an iron core transformer and a 7805 (TO-3), but I want to change to ferrite core because the iron transformer and the 7805 get hot when they work for some time. Thanks in advance. Miguel PS: If there is a thread about this I apologise.
The Rise And Fall Of The Full Stack Developer Editor’s note: Peter Yared is the founder and CTO of Sapho and was formerly the CTO/CIO of CBS Interactive. It seems as though everyone in tech today is infatuated with the full-stack developer. Full stack may have been possible in the Web 2.0 era, but a new generation of startups is emerging, pushing the limits of virtually all areas of software. When I first started programming computers as a kid in the pre-mobile, pre-web late 1970s/early 1980s, a single person typically wrote a complete software program from start to finish, and there weren’t many other layers of software between the programmer and the hardware. Programming applications quickly evolved into a team sport with the advent of client/server computing in the late 1980s and early 1990s, and the wave of Internet computing in the late 1990s and early 2000s. By the mid-2000s, creating virtually anything — from simple websites to next-generation SaaS services — became prohibitively expensive.

Being a Full Stack Developer The barrier of entering the web development industry as a web developer is still low, but it’s getting increasingly complex. The dynamic nature of the whole industry makes requirements shift often to the most popular and “next best thing” tools and programming languages. Gone are the days when only one programming language or a very specific process was required from a developer. Nowadays programmers must know a range of technologies across multiple platforms in order to do good work. What does a full-stack developer mean? The term full-stack means developers who are comfortable working with both back-end and front-end technologies. To be more specific, it means that the developer can work with databases, PHP, HTML, CSS, JavaScript and everything in between, also, venturing as far as converting Photoshop designs to front-end code. What full-stack meant in 2000 and what it means now? 2000 was a long time ago, in that year PHP 4.0 was released. System administration: Web development tools:
Protocole I.P. ; calculs de sous-réseaux Repérage Une machine est repérée sur le réseau par une adresse IP (IPx) associée à un masque (Mx) qui sont chacun un nombre binaire de 3 bits organisé en 4 octets. Le masque sert à repérer le réseau ou le sous-réseau auquel la machine appartient. Identification du réseau Diffusion et nombre d'hôtes L'adresse de diffusion (Bx) d'un réseau ou d'un sous-réseau est une adresse réservée ( la dernière des adresses possibles du dit réseau). La capacité maximale du réseau ou du sous-réseau, appelée le nombre d'hôtes (Hx), s'obtient aisément par le nombre n de bits à 1 du masque Mx : Hx = ; 2 adresses en moins car une est réservée pour l'adresse du sous-réseau lui-même et l'autre pour la diffusion du sous-réseau ("broadcast").Dans l'exemple 1, H1 = 254 ; dans l'exemple 2, H2 = 65 534 et dans l'exemple 3, H3 = 62 . Plus Hx est grand et plus la bande passante du réseau s'amenuise et le traffic de diffusion augmente. Visibilité des machines entre elles
Welcome To The Unicorn Club: Learning From Billion-Dollar Startups Editor’s note: Aileen Lee is founder of Cowboy Ventures, a seed-stage fund that backs entrepreneurs reinventing work and personal life through software. Previously, she joined Kleiner Perkins Caufield & Byers in 1999 and was also founding CEO of digital media company RMG Networks, backed by KPCB. Follow her on Twitter @aileenlee. Many entrepreneurs, and the venture investors who back them, seek to build billion-dollar companies. Why do investors seem to care about “billion dollar exits”? Historically, top venture funds have driven returns from their ownership in just a few companies in a given fund of many companies. So, we wondered, as we’re a year into our new fund (which doesn’t need to back billion-dollar companies to succeed, but hey, we like to learn): how likely is it for a startup to achieve a billion-dollar valuation? To answer these questions, the Cowboy Ventures team built a dataset of U.S. Learnings to date about the “Unicorn Club”: So, what does this all mean?
I2C Installation for Raspberry Pi – Step by Step Guide | SK Pang Electronics Ltd This is a step by step guide on installation I2C driver for the Raspberry Pi. It is for the Raspbian image. Raspberry Pi Starter Kits Make sure your Raspberry Pi is connected to the internet when installing the drivers. The new Raspbian distro already have the I2C driver installed but they are disabled by default. sudo nano /etc/modprobe.d/raspi-blacklist.conf then add a # on the 3rd line. Press CTRL X then y to save and exit. Next edit the modules file by: sudo nano /etc/modules Add i2c-dev to a new line. Now install the i2c-tools package by: sudo apt-get install i2c-tools If you get a 404 error do an update first: sudo apt-get update then run the install the i2c-tools again. Note : The installation could take a few minutes to do, depend on how busy the server is. Now add a new user to the i2c group: sudo adduser pi i2c Reboot the machine by: sudo shutdown -r now After the reboot test to see any device connected by: sudo i2cdetect -y 0 If your board is the Rev 2 type this: sudo i2cdetect -y 1 .
I'm a non-Jew raising a Jewish kid | Elizabeth Raphael Kveller via JTA — 2015 was a year of change for me, facilitated largely by the birth of my lovely dumpling of a daughter in February. Among the normal challenges of being a first-time parent (learning to cobble together a working brain when it has been addled by lack of sleep, perfecting the art of acting casually when your child decides to poop on you in a public place, and so on), I had the additional challenge of being a non-Jewish woman raising a Jewish daughter.

A bit of background on me: My religious upbringing can best be described as “vaguely Christian.” I went to a Catholic church a handful of times as a child, but I was never baptized, nor did I undergo confirmation (in fact, I had to do a quick Internet search while writing this article to make sure that “confirmation” was even the right term for the process I was thinking of). He and I met through a mutual friend in 2007.
