Exclusive: Professor Rachid Guerraoui from EPFL comments on how transactional memory influences our future

August 17th, 2017 No comments

At one of the programming forums we were pleased to be able to speak to Rachid Guerraoui (École Polytechnique Federale de Lausanne, EPFL), whose research is devoted to concurrent and distributed programming, across systems ranging from multiprocessors to wide-area networks. This topic is of high interest to us, as Devexperts solutions for the financial industry widely use concurrent algorithms.

3 easy steps to improve quality of your concurrent programs

February 12th, 2014 No comments

Weinberg’s Second Law says that if builders built buildings the way programmers wrote programs, the first woodpecker that came along would destroy the civilization. In practice it means that any software has to be tested very carefully to fix bugs in it in the earliest stage of its lifecycle.

Rapid expansion of multicore and multiprocessor systems makes software developers write parallel programs to use system resources as efficiently as possible. And here another big hazard is hidden – errors, related to incorrect usage of multiple threads of execution. On big production servers it’s a much bigger threat than it seems, because the program code is physically executed on different cores or processors, and concurrent issues arise in their full capacity. Most well-known problems of such a kind are deadlocks and data races. All concurrent issues are hard to detect manually or by testing, because their nature is essentially nondeterministic. Data race detection is an especial issue, because the effect of their occurrence may become apparent much later. When a data race occurs, global data are corrupted, but the application itself doesn’t halt, it continues to work with incorrect data, and who knows when one would notice it. Data races may be really dangerous – e.g. data race was the cause of accidents with Therac-25, the radiation therapy machine, that gave massive overdoses of radiation to six patients. Also data race was one of the causes that led to the Northeast blackout of 2003 that affected more than 50 million people in the US and Canada.

Using HTML5 for developing mobile applications

March 6th, 2013 1 comment

I’d like to dedicate this post to Mark Zuckerberg, even though I fully realize he doesn’t care at all. But still his famous quote with regard to HTML5 being very impactful started many discussions and changed the way how a lot of people saw the mobile technology landscape at that moment.
He’s usually quoted like this:

“When I’m introspective about the last few years I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native… because it just wasn’t there.”

The Agile approach in software development: why should you care?

July 26th, 2012 2 comments

Our highest priority is to satisfy the customer through 
early and continuous delivery of valuable software.
Manifesto for Agile Software Development, 2001

In recent years, Agile methodology has become increasingly popular in the software industry. The reason is simple— the Agile approach results in increased customer satisfaction. As a consequence, this increases the competitiveness of the development company, and both sides win. As the software market continues to develop and software products and technologies keep expanding into more web and mobile applications, there is a rapidly increasing demand for functionality and quality in developed software, time-to-market and speed of response to customer’s needs. These days customer of software development services can no longer afford himself to ignore the question of how organized the production process is in the development company so that they can know what to expect and when. So, what does “Agile” mean in software development? Is this just another buzzword, or a real chance to meet these new challenges? How it can affect the customer’s business and their ROI? Let’s examine this in more detail.
