Open Source Matters: 6 Source Code Search Engines You Can Use For Programming Projects The Open source movement is playing a remarkable role in pushing technology and making it available to all. The success of Linux is also an example how open source can translate into a successful business model. Open source is pretty much mainstream now and in the coming years, it could have a major footprint across cutting edge educational technology and aerospace (think DIY drones). Open source projects need all the help they can get. Ohloh Ohloh Code says it is one of the largest and more comprehensive code search engines with more than 10+ billion lines of code indexed and updated FOSS software directories. Krugle Krugle is an open source search portal which taps into open source search repositories like Apache, JavaDocs, and SourceForge among others. SearchCode SearchCode sifts through 16 billion lines of open source code from code repositories like GitHub, BitBucket, CodePlex, SourceForge, Fedora and more. NerdyData Symbol Hound Merobase
Social Network Login Status Detector Demo This is a demonstration of how a website can detect which Social Networks a user is logged into when they visit. In my tests it seems to work in all the major browsers (Firefox, Chrome, IE 7+, Safari and Opera). For details please see my post on how to detect which social networks your visitors are logged into. You are not currently logged in to Facebook You are not currently logged in to Twitter You are not currently logged in to Google You are not currently logged in to GooglePlus If you want to prevent sites from being able to detect this then for Firefox you can try RequestPolicy or NoScript.
Iconoclasm What can be said about the save icon? It is a diskette. It is often blue. And of course, as others have pointed out, many (soon to be most) people using computers today have never touched one and never will. Yet you could say the same for a the “home” icon (millions will never own a house), the “phone” icon (used a model 500 lately?) The simple fact is that there is a shared visual orthography in which some things are acknowledged worldwide, and this overpowers the logical suggestion to constantly update it. The snake will not run out of tail to eat. The Noun Project is a fun exploration of this concept — that there are, say, 32×32-pixel versions of every concept in the dictionary. But what are the chances these new ideas are going to be truly new? Maybe I lost you there. What did you expect when our data started coming from nowhere and being beamed into the blue? In the meantime, we will be seeing more and more creative reflections of the real world upon the virtual, and vice versa.
Formula for Human Genius and Creativity High IQ in high demand Intelligence, creativity and genius are generally regarded as highly valuable assets of the human mind. As a strong positive correlation exists between IQ and the median earned income, most people would gladly boost their IQ, improve creativity or accept being called a genius. Exceptions to this rule are few and most revolve around a claim that intelligence may be an obstacle on the way towards universal happiness. Here are a few exemplary arguments against human intelligence listed by the detractors of genius: high intelligence reveals existential truths and as such is highly depressive high intelligence prevents atavistic enjoyment of relationships high intelligence is a source of envy and other bad feelings in others high intelligence leads to inhuman behaviors and most sophisticated forms of evil In this article, I will tacitly ignore the above claims and assume that you would gladly become more intelligent, creative or innovative. What is intelligence?

7 Python Libraries you should know about In my years of programming in Python and roaming around GitHub's Explore section, I've come across a few libraries that stood out to me as being particularly enjoyable to use. This blog post is an effort to further spread that knowledge. I specifically excluded awesome libs like requests, SQLAlchemy, Flask, fabric etc. because I think they're already pretty "main-stream". If you know what you're trying to do, it's almost guaranteed that you'll stumble over the aforementioned. This is a list of libraries that in my opinion should be better known, but aren't. 1. pyquery (with lxml) pip install pyquery For parsing HTML in Python, Beautiful Soup is oft recommended and it does a great job. Just how slow? What immediately stands out is how fast lxml is. So either slow and easy to use or fast and hard to use, right? Wrong! Enter PyQuery Oh PyQuery you beautiful seductress: from pyquery import PyQuerypage = PyQuery(some_html) last_red_anchor = page('#container > a.red:last') Easy as pie. 2. dateutil
THE BIG MODS: List them, stalk them and cuddle them! Post all major mods here. - Skyrim Mods original thread this from the Previous OP:My friend Winterhold Guard told me to post a new thread where it will be constantly updated, but i m not sure what Solitude Guard will say. NONETHELESS, HERE WE GO! Ulfric better give me a pay rise for this, perhaps promote me to legate. Damn dragonborn took all the prizes while i still stand here and guard that windhelm gate. For easy browsing, stalking and exposure to the big Skyrim mods in development. They need time, but they also need support and recognition! ~if you know of a big mod that is not listed here, let me know. fully finished(or finished but adding more bugfixes and expansions) / some version released / almost at first release / hot in-progress / just starting / hiatus/dead/no news New lands+ big extensions to the vanilla world of skyrim(I think they all include quests and some include many more things) Babylon (dead) Beyond FalskaarRELEASED!

“I Need Practice Programming”: 49 Ideas for Game Clones to Code So you know a little bit about programming (perhaps you've read the free book, "Invent Your Own Computer Games with Python", a free programming book for beginners whose author shamelessly plugs at every chance) but you want to get better at coding. You can't seem to find any open source projects that are at your level or easy for new people to contribute to. You've gone through a few of the practice problems at Project Euler but you want to create something more substantial, or at least a cool thing you can show your friends. (Not that finding the 31337th prime number isn't cool.) Here's a list of game clone ideas for you to implement. Orisinal Games: The Orisinal website has a great collection of Flash games with very simple mechanics that can be copied. I especially recommend Winter Bells, A Daily Cup of Tea, Bugs, and Hold the Rope! The Wikipedia entry for video game clones also lists some ideas. 1.

Tic Tac Toe An Introduction to Artificial Intelligence What is Tic Tac Toe? Tic Tac Toe is simply an awesome game. (Although I do have to say that I really think its original name - noughts and crosses - is a whole lot cooler). It is simple and easy to play wherever you are. The success of this simple but yet intriguing game is quite staggering and therefore even some mathematicians had a peek at it. There is some debate on where this game originated; theories are ranging from ancient Egypt to the Roman Empire. The Stats One could assume that there are 9! 131,184 (1st player)77,904 (2nd player)46,080 (tie) This might seem like a lot but for a Computer this is a joke. There are 138 terminal positions after assuming symmetries. 91 (player 1)44 (player 2)3 (tie) A little bit of Game Theory Mathematics has a really interesting branch called Game Theory. So how is this important for Tic Tac Toe? Tic Tac Toe is something called a zero-sum game. Perfect Play The famous Tic Tac Toe xkcd. (#832) The Setup Minimax #!
Writing a game in Python with Pygame. Part I Introduction Games are one of the most applicative areas of programming. To write even the simplest games, you have to get into graphics, math, physics and even AI. If you’re a fan of Python (and even if you aren’t) and are interested in games, Pygame is a great library for game programming, and you should definitely check it out. There are quite a lot of Pygame tutorials on the web, but most of them are basic. This tutorial explicitly encourages you to tinker with the code. Preliminaries For reasons I’ve mentioned above, this tutorial is not for complete beginners. Here, I assume that you have the following knowledge: Python (you don’t have to be an advanced user, but not a complete beginner either)Basics of math and physics (vectors, rectangles, laws of movement, probability, etc.). Oh, and another thing… This tutorial will focus on a 2D game. 3D is a whole new level of complexity, and I prefer a simpler but complete game to a half-baked 3D demo. Let’s get started The code Pygame’s docs
Divisor function Divisor function σ 0 ( n ) up to n = 250 Sigma function σ 1 ( n ) up to n = 250 Sum of the squares of divisors, σ 2 ( n ), up to n = 250 Sum of cubes of divisors, σ 3 ( n ) up to n = 250 In mathematics , and specifically in number theory , a divisor function is an arithmetic function related to the divisors of an integer . A related function is the divisor summatory function , which, as the name implies, is a sum over the divisor function. Definition [ edit ] The sum of positive divisors function σ x ( n ), for a real or complex number x , is defined as the sum of the x th powers of the positive divisors of n . where is shorthand for " d divides n ". The aliquot sum s(n) of n is the sum of the proper divisors (that is, the divisors excluding n itself, A001065 ), and equals σ 1 ( n ) − n ; the aliquot sequence of n is formed by repeatedly applying the aliquot sum function. Example [ edit ] For example, σ 0 (12) is the number of the divisors of 12: while σ 1 (12) is the sum of all the divisors: and
Two-Tiered A* Pathfinding In my main article, A* Pathfinding for Beginners, I described A* in very general terms, and described how to create a single all-purpose pathfinding function. Creating only one pathfinding function, however, can be needlessly limiting. Consider the following RPG situation, and a swordsman who wants to pathfind around a nearby wall: Given this kind of map, you could place nodes in a variety of ways, and use a variety of densities. In this example, let's use a high-density node network, as is shown below. In this graphic, the white nodes are walkable. As you can see, using this tightly packed node network, we can pathfind not only around the nearby wall but also between the wall and the nearby barrel in the process. Well, that is pretty cool in short-distance situations, but what do we do if we need to pathfind across the entire map? So let's look at an alternative. In this example, the nodes are in the center of the large isometric diamonds. Putting the Two Together Well, that's it.
