Case Studies Multicore Performance File Systems and Storage RIA Development Making the Move to AJAX What a software-as-a-service provider learned from using an AJAX framework for RIA development Queue on Reddit GameDay Exercises Case Study It's very nearly the holiday shopping season and something is very wrong at a data center handling transactions for one of the largest online retail operations in the country. The good news is that it's not a real disaster—though it could have been. Many operations are turning to resilience engineering not in hopes of becoming impervious to failure, but rather to become better able to adapt to it when it occurs. In the early 2000s, Amazon created GameDay, a program designed to increase resilience by purposely injecting major failures into critical systems semi-regularly to discover flaws and subtle dependencies. Participants include Jesse Robbins, the architect of GameDay at Amazon, where he was officially called the Master of Disaster.

How are Lean, Agile, and Devops related to each other?
You hear a lot about various agile approaches. Things like Lean, Scrum, Kanban, and Devops seem to be important but it’s hard to sort them out. How do they relate to each other and where to start? Let me try to structure these ideas for you. Lean is the basis of Agile Lean tells you to optimize the end-to-end process which creates value for your customer – from the initial idea to collecting cash. Build product development flow on top of Lean Creating value for your customers is all about finding and verifying product ideas, implementing these ideas, and running them to benefit your users. The three aspects of product development flow Lean Startup or Running Lean: here Eric Ries and Ash Maurya talk about how to create a learning cycle during feature discovery. A word of warning: individually, none of these agile processes is able to optimize the entire flow. Lean principles are the basis of your entire product development flow. What are your thoughts on the interplay of these ideas?
I’m writing this post in an apt state: low-sleep, busy, disorientated, and interrupted. I try all the remedies: Pomodoro, working in coffee shops, headphones, and avoiding work until being distraction free in the late night. But it is only so long before interruption finds a way to pierce my protective bubble. Like you, I am programmer, interrupted. Unfortunately, our understanding of interruption and remedies for them are not too far from homeopathic cures and bloodletting leeches. But what is the evidence and what can we do about it? The costs of interruptions have been studied in office environments. For programmers, there is less evidence of the effects and prevalence of interruptions. Interruptions of Programmers Based on a analysis of 10,000 programming sessions recorded from 86 programmers using Eclipse and Visual Studio and a survey of 414 programmers (Parnin:10), we found: A programmer takes between 10-15 minutes to start editing code after resuming work from an interruption.
General, Debugging, Options Dialog Box
To access the General page, open the Tools menu and choose Options. In the Options dialog box, expand the Debugging node and choose General. This page lets you set the following general debugging options: Ask before deleting all breakpoints Requires confirmation before completing the Delete All Breakpoints command. Break all processes when one process breaks Simultaneously breaks all processes to which the debugger is attached, when a break occurs. Break when exceptions cross AppDomain or managed/native boundaries In managed or mixed-mode debugging, the common language runtime can catch exceptions that cross application domain boundaries or managed/native boundaries when the following conditions are true: 1) When native code calls managed code by using COM Interop and the managed code throws an exception. 2) When managed code running in application domain A calls managed code in application domain B and the code in application domain B throws an exception.

“…we’ve implemented every property in CSS 2.1 and are closing in on our goal of complete support for the CSS 2.1 specification by the time we release.” If you were to guess who recently made that statement you’d be forgiven for thinking it came from the Opera, Safari, or Firefox team; they have always seemed to be the most standards-conscious browser vendors. In fact, this quote comes from Doug Stamper of Microsoft, regarding Internet Explorer 8. It seems the very thing web designers have been asking for—mature support for CSS2.1 across all major browsers—is actually about to happen. Back in Tech Times #185, I wrote about what this would mean to web designers in Table-Based Layout Is The Next Big Thing. There were mixed reactions to that article, particularly on the point of row and column spans. Well, in my research for an as yet unannounced, potentially controversial book on CSS, I’ve figured out how to simulate row and column spans in CSS tables. Nothing Up My Sleeve…

Why Leading Application Development Team In India Uses Git? | Blog for App Development
For agile app development, better source control and shorter cycles are required. Here we are sharing brief info about using Git and the Git-flow method of managing commits, branches, and merges. Delivering software application is not used to be tough. You would write code, developer would work on its build and operations. What comes next? You might need to fix bugs, but next project is in the line and the next big thing. Everything has now changed and developers are no longer separated from the business. Source control is popular as a key element of the tool chest along with Git. Picking a tool can never solve your continuous development issues overnight- developers will need to implement proper workflow to determine new ways of writing and building code. Git-flow model is intended to duplicate the structure of a modern, skilled development team. For continuous delivery, developers will need a continuous development model. Like this: Like Loading...

Personal Development and Human Potential
How can we define personal development and how does it relate to human potential? Personal development is not measured by financial, social or external success. Instead it is determined by our efforts to develop our intellectual, physical and spiritual aspects in order to reach our full human potential. In the process of developing ourselves, we also strive to express our talents and abilities for the enrichment and benefit others. Unfortunately, in today's instant gratification culture there has been an unhealthy trend towards 'get rich quick' (substitute thin, beautiful, fit, etc.) schemes gaining ground. It implies that if you are rich enough, thin enough, or beautiful enough, you will be happy. I'm sure most of us have read, or heard the woeful tales of lottery winners who attained massive fortunes only to be broke soon after their windfalls. The Lesson: There are no "quick fixes" or short cuts to personal development. These behaviors include:
