How Xamarin Gave Mono a Life After Novell

Submitted by lucas_maximus 2011-12-14 General Development 1 Comment

On May 4, 2011, Novell conducted a large round of layoffs as part of its post-merger with Attachmate -- and one of the casualties was the 30-person team that worked on Mono. Fewer than two weeks after Novell swung the axe, de Icaza announced the launch of Xamarin. Xamarin is going strong: The company is generating self-sustaining revenue and is on a steady product launch schedule. (Last week it rolled out Mono for Android 4.0, which lets developers make apps that work with the latest version of Android, Ice Cream Sandwich.)

Why We Need More Programming Languages

Guest post by snydeq 2011-12-11 General Development 50 Comments

Fatal Exception's Neil McAllister writes in favor of new programming languages given the difficulty of upgrading existing, popular languages. 'Whenever a new programming language is announced, a certain segment of the developer population always rolls its eyes and groans that we have quite enough to choose from already,' McAllister writes. 'But once a language reaches a certain tipping point of popularity, overhauling it to include support for new features, paradigms, and patterns is easier said than done.' PHP 6, Perl 6, Python 3, ECMAScript 4 -- 'the lesson from all of these examples is clear: Programming languages move slowly, and the more popular a language is, the slower it moves. It is far, far easier to create a new language from whole cloth than it is to convince the existing user base of a popular language to accept radical changes.'

Welcome to Ceylon

Submitted by fran 2011-11-25 General Development 12 Comments

"Ceylon is a programming language for writing large programs in a team environment. The language is elegant, highly readable, extremely typesafe, and makes it easy to get things done. And it's easy to learn for programmers who are familiar with mainstream languages used in business computing. Ceylon has a full-featured Eclipse-based development environment, allowing developers to take best advantage of the powerful static type system. Programs written in Ceylon execute on any JVM."

What I’m Thankful For As A Developer

Guest post by snydeq 2011-11-23 General Development 31 Comments

Fatal Exception's Neil McAllister gets into the holiday spirit with a post that gives thanks to technical advances for developers, including open source tools, modern IDEs, and distributed version control. 'I'm old enough to remember when performance-critical routines meant hand-coded assembly language and sometimes even keying in machine code as hexadecimal digits. We've come a long way since those bad old days, and not surprisingly we owe a lot of our progress to technology. So for this Thanksgiving, here are just a few of the modern advances for which I, as a developer, give thanks.' What are you giving thanks to?

PyPy 1.7 Widens the Performance “Sweet Spot”

Guest post by fran 2011-11-22 General Development No Comments

"The PyPy development team has released version 1.7 of its 'very compliant' Python interpreter with integrated tracing just-in-time compiler. The developers say that the focus of the new update was widening the range of code that PyPy can speed up, which the developers refer to as the 'sweet spot'. In their benchmarks, PyPy 1.7 performs approximately 30 per cent faster than 1.6 and 'up to 20 times faster on some benchmarks'."

The Futility of Developer Productivity Metrics

Guest post by snydeq 2011-11-17 General Development 21 Comments

Fatal Exception's Neil McAllister discusses why code analysis and similar metrics provide little insight into what really makes an effective software development team, in the wake of a new scorecard system employed at IBM. "Code metrics are fine if all you care about is raw code production. But what happens to all that code once it's written? Do you just ship it and move on? Hardly - in fact, many developers spend far more of their time maintaining code than adding to it. Do your metrics take into account time spent refactoring or documenting existing code? Is it even possible to devise metrics for these activities?" McAllister writes, "Are developers who take time to train and mentor other teams about the latest code changes considered less productive than ones who stay heads-down at their desks and never reach out to their peers? How about teams that take time at the beginning of a project to coordinate with other teams for code reuse, versus those who charge ahead blindly? Can any automated tool measure these kinds of best practices?"

Tough Tests Flunk Good Programmer Job Candidates

Guest post by snydeq 2011-11-03 General Development 54 Comments

Fatal Exception's Neil McAllister discusses the use of quizzes and brain-teasers in evaluating potential software development hires, a practice that seems to be on the rise. 'The company best known for this is Google. Past applicants tell tales of a head-spinning battery of coding problems, riddles, and brain teasers, many of which seem only tangential to the task of software development. Other large companies have similar practices -- Facebook and Microsoft being two examples,' McAllister writes. 'You'll need to assess an applicant's skill in one way or another, but it's also possible to take the whole interview-testing concept too far. Here are a few thoughts to keep in mind when crafting your test questions, to avoid slamming the door on candidates unnecessarily.'

Extending Native Features To HTML5 Web Apps

Guest post by snydeq 2011-11-03 General Development 9 Comments

A small company called AppMobi is enabling developers to create HTML5 apps that tap into native hardware and OS capabilities of mobile devices, such as gravity sensing, accelerometer, GPS, camera, sound and vibration, and the file system, InfoWorld reports. 'Its MobiUs browser for iOS implements HTML5's DirectCanvas API for gaming, as well as the HTML5 local storage API for saving executables and data in the browser cache so that apps can run offline. But what makes MobiUs more than just yet another browser is the set of libraries AppMobi provides app developers to access native hardware and enable push messaging from Web apps.'

John McCarthy Dies, Age 84

Submitted by JAlexoid 2011-10-25 General Development 19 Comments

The news already hit HackerNews late last night, but at that time there was no confirmation so I decided to wait until we knew for sure. Well, after Dennis Ritchie and Steve Jobs, the technology world lost another great mind yesterday. Stanford has confirmed that John McCarthy, the creator of LISP and the father of artificial intelligence, has passed away, age 84.

Microsoft’s Roslyn: Reinventing the Compiler as we Know it

Guest post by twitterfire 2011-10-24 General Development 80 Comments

"Looking past the Metro hype, the Build conference also revealed promising road maps for C#, Visual Studio, and the .Net platform as a whole. Perhaps the most exciting demo of the conference for .Net developers, however, was Project Roslyn, a new technology that Microsoft made available yesterday as a Community Technology Preview. Roslyn aims to bring powerful new features to C#, Visual Basic, and Visual Studio, but it's really much more than that. If it succeeds, it will reinvent how we view compilers and compiled languages altogether."

What’s Hot (or Not) In Scripting Languages

Guest post by snydeq 2011-10-17 General Development 32 Comments

Just-in-time compilers, browser wars, and developer enthusiasm are just a few of the trends separating today's hot scripting languages from the pack. InfoWorld's Peter Wayner surveys programmers, commit logs, search engine traffic, and book sales data to provide a barometer of scripting languages -- JavaScript, ActionScript, Perl, Python, Ruby, Scala, R, and PHP -- providing a best-guess forecast of which languages are rising and falling in scripting hipness.

Google Dart Unveiled: Farewell, JavaScript

Submitted by twitterfire 2011-10-10 General Development 41 Comments

"Google has released an early version of Dart, a new programming language designed to take some of the pain out of developing applications for the Web. But while it's an evolutionary improvement on JavaScript, Dart faces a hard uphill battle for acceptance."

IT Inferno: The Nine Circles Of IT Hell

Guest post by snydeq 2011-10-03 General Development 3 Comments

InfoWorld's Dan Tynan takes us on a tour of the nine circles of IT hell, a place 'not unlike the underworld described by Dante in his Divine Comedy.' 'But here, in the data centers, conference rooms, and cubicles, the IT version of this inferno is no allegory. It is a very real test of every IT pro's sanity and soul,' Tynan writes. From IT limbo, to tech lust, to stakeholder gluttony, to tech-pro treachery, the IT inferno is not buried deep within the earth, it's just down the hall. 'Thankfully, as in Dante's poetic universe, there are ways to escape the nine circles of IT hell. But IT pro beware: You may have to face your own devils to do it. Shall we descend?'

Announcing Opa: Making Web Programming Transparent

Guest post by hbbio 2011-08-25 General Development 25 Comments

"Opa, a new opensource programming language aiming to make web development transparent has been publicly launched. Opa automatically generates client-side Javascript and handles communication and session control. The ultimate goal of this project is to allow writing distributed web applications using a single programming language to code application logics, database queries and user interfaces. Among existing applications already developed in Opa, some are worth a look. Best place to start is the project homepage which contains extensive documentation while the code of the technology is on GitHub. A programming challenge ends October 17th." This is weird. 'Opa' is the nickname my friends gave me 6 years ago. It's still used more often than my actual name...

C++0x Is Unanimously Approved

Submitted by subterrific 2011-08-14 General Development 87 Comments

The final ISO ballot on C++0x closed on Wednesday, and we just received the results: Unanimous approval. The next revision of C++ that we've been calling "C++0x" is now an International Standard! Geneva will take several months to publish it, but we hope it will be published well within the year, and then we'll be able to call it "C++11."

Six Python Web Frameworks Compared

Guest post by snydeq 2011-08-10 General Development 9 Comments

InfoWorld's Rick Grehan provides an in-depth comparison of six Python Web frameworks, including CubicWeb, Django, Pyramid, Web.py, Web2py, and Zope 2. 'No matter what your needs or leanings as a Python developer might be, one of these frameworks promises to be a good fit,' Grehan writes. 'As usual, the choice is highly subjective. You will find zealots for each product, and every zealot is able to present rational reasons why their chosen framework is superior.'

Could You Live Without Blocking Calls?

Neolander 2011-05-27 General Development 58 Comments

After having an interesting discussion with Brendan on the topic of deadlocks in threaded and asynchronous event handling systems (see the comments on this blog post), I just had something to ask to the developers on OSnews: could you live without blocking API calls? Could you work with APIs where lengthy tasks like writing to a file, sending a signal, doing network I/O, etc is done in a nonblocking fashion, with only callbacks as a mechanism to return results and notify your software when an operation is done?
