Stop wasting billions of dollars using the wrong software languages | VentureBeat | Dev | by Aaron Contorer Aaron Contorer created FP Complete, a commercial Haskell IDE and deployment platform. Software drives the innovation economy, from big data and software-defined networks to mobile applications and social media. Yet literally billions of dollars are wasted due to excess project failures, bug fixes, and maintenance nightmares. High level but hands-on Our upcoming DevBeat conference, Nov. 12-13 in San Francisco, will have a lot more on this topic. workshopsteck talkslive Ask-Me-Anythinghardware hacking It’s all aimed at boosting your code skills, security knowledge, hardware hacking, and career development. This problem is relatively unknown and perpetuated because the vast majority of programmers, reporters, and managers do not know of a viable alternative and just accept that this is the way things always are. The Haskell alternative The solution is Haskell, the purest functional language that has been in development for over 20 years. Haskell applied
The Best Websites to Learn Coding Online | TechGrey The Learn to Code movement( a movement which went viral among teens) with the backing of the likes of Obama and Bill Gates, is picking up momentum worldwide and it is actually a very good thing as even basic programming skills can have a major impact on you and your Imagination and Creativity. If you can teach yourself how to write code, you will gain a competitive edge over your peers, you can think more Creatively and thus you can tackle problems more efficiently. Don’t just download the latest app, help redesign it. Don’t just play on your phone, program it. — Obama. There is no reason in why you should not know the basics of coding. Gone are the days when you had to enroll in expensive computer training classes as now exist a plethora of web-based courses that will surely help you learn programming at your own pace in the comfort of your web browser. Teach Kids to Code There’s also an app called Scratch, an MIT project that allows kids to program their own stories and games visually.

Parsowanie plików XML Poniższy kurs powstał w celu uzyskania oceny z kursu komputerowego poświęconemu językowi Python. Ma on na celu przybliżenie podstawowych zagadnień z dziedziny parsowania dokumentów XML w języku Python. Kurs nie miał być dokumentacją żadnego z modułów poświęconych temu zagadnieniu ale ma na celu przedstawić i nauczyć zagadnień podstawowych, które połączone ze znajomością języka Python umożliwią rozwiązywać dużo bardziej skomplikowane problemy związane z parsowaniem dokumentów XML. Poniższy kurs zawiera: 1. Czym jest XML Aby przejść do parsowania plików XML na początku trzeba się dowiedzieć czym jest ten XML. <panstwa_europejskie><panstwo><nazwa jezyk="polski">Polska</nazwa><nazwa jezyk="oryginalny">Polska</nazwa><stolica>Warszawa</stolica><powierzchnia>312 tys. km 2. Jak widać jest to dokument, który w znacznym stopniu ułatwia przechowywanie danych. 2. Łatwym sposobem na uzyskanie dostępu do pliku XML jest stworzenie obiektu Document: 3. 4. W ten sposób otrzymamy: <stolica>Berlin</stolica> 5.
