Welcome to your first taste of Haskell! Let's try Haskell right now!

KWallet is a service provided by KDE that provides a convenient way to save and read this kind of data. Lets take a look at a simple example of how we can use the KWallet service from a Python application.

Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language, but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code.

This makes Cython the ideal language for wrapping external C libraries, and for fast C modules that speed up the execution of Python code.

The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine. It is up to 50 times faster than local RPC via SOAP, requires less resources on the web-server side. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java.

Security and encryption is getting ever more important in today's computer networks, being it SSL secured web sites, encryption of data or mail, secure logon to mention just a few. But security is expensive, right? Not anymore....

StartCom, the vendor and distributor of StartCom Linux Operating Systems, also operates MediaHost™, a hosting company, which offered its clients, SSL secured web sites with certificates signed by StartCom for many years. That's where the idea originated: Free SSL certificates!

The development of the typical app cost $35,000 and the median paid app earns $682 dollars per year after Apple took its cut. You see where this is going.. We get to break even on our App Development costs in... 51 years. I'd say the iPhone battery will need replacing before then, and perhaps our grand kids have grown tired with that oldfashioned antique toy by then. But maybe - just maybe - without any updates to our app, we can sustain 51 years of continuous sales and recover our initial investment. Yeah, and this is obviously without covering any of our marketing costs, and gives us no profit yet, etc...

Just to break even.

If you take that absolute lowest end of the two estimates, $15,000 and do our app 'dirt cheap' - even then, it will take 22 years to recover our costs.

Designing an HTML email that renders consistently across the major email clients can be very time consuming. Support for even simple CSS varies considerably between clients, and even different versions of the same client.

We’ve put together this guide to save you the time and frustration of figuring it out for yourself. With 23 different email clients tested, we cover all the popular applications across desktop, web and mobile email.

A vast proportion of software at work today is horribly over-engineered for its task. And I’m not talking about the interfaces, about having too many controls or options for the users. These are, indeed, terrible sins but they are the visible ones. The worst of the overengineering goes on under the surface, in the code itself.

...

The most insidious cause of overengineering is over-generalizing. We will over-generalize anything given half a chance. Writing code to work with a list of students? Well, we might want to work with teachers and the general public someday, better add a base People class and subclass Student from that. Or Person and then EducationPerson and then Student. Yes, that’s better, right?

Only, now we have three classes to maintain each with their own virtual methods and interfaces and probably split across three different files plus the one we were working in when a one-line dictionary would have been fine.

You never develop code without version control, why do you develop your database without it?

LiquiBase is an open source (LGPL), database-independent library for tracking, managing and applying database changes. It is built on a simple premise: All database changes are stored in a human readable yet trackable form and checked into source control.

Our core product is an open source software involvement engine. For developers, we provide tools to demonstrate and broaden their experience and expertise in the open source community. Our vision is to make the open source community better connected, more productive, and ultimately well rewarded for its expertise.
