I once said on stage at Glue that the reason I loved node.js was, quite frankly, that it's a language and with a programming language you can do, well, anything.

But like most things just because you can, doesn't always mean you

The follow up article to Welcome to the Age of the Consumer: No Opinion Matters More Now we go into how to take advantage of those essential first few days or even minutes that you have your potential customer’s attention in order to follow through on heightened expectations of ste...
Already, in the few short years that cloud has been in the mainstream IT conversation, we've seen the rise of "bare metal" cloud (thus ending the illusion of cloud's infinite capacity to users), the substitution of virtualized machines by Docker containers, and most recently, the poten...
Over the past year I reckon I have spoken to more than a thousand Developers/IT Os/DevOps folk through customer calls, demos of Logentries, at conferences such as Velocity, DevOpsDays, AWS re:Invent as well as a bunch of other more low key meetups across US and Europe. Naturally, on...

Unless you have been living under a rock the last year, you have probably heard about Docker. Docker describes itself as an open platform for distributed applications for developers and sysadmins. That sounds great, but why does it matter? Wait, virtualization isn’t new!? Virt...

When I took my operating systems fundamentals course in college I was taught that an operating system provides very specific capabilities that provides users with access compute resources for building and running applications. Over time as networking capabilities and bandwidth increase...
DevOps is a discontinuous innovation in the way organizations develop and deliver software. And as with any new discontinuous innovation, the implication is that creative destruction will follow. Companies that hold on to legacy business and technology models, without pursuing the ev...
Here’s the presentation I gave at the Linux Foundation’s CloudOpen in Dusseldorf on October 13, 2014 titled Mixing Your Open Source Cloud Cocktail Add two parts virtualization, one part orchestration add a little networking shake and pour. Unfortunately cloud computing isn’...
If you're an executive that's concerned about the high-cost of proprietary software, you're not alone. If your IT team pushes back whenever Line of Business leaders ask them for feature enhancements that goes beyond the limits of the commercial software packages they've licensed, then ...

For a concept that is barely a couple years old, DevOps is red hot. No conversation about software development is considered complete without the mention of this new buzz word. But the growth in its popularity has also given rise to several misconceptions. Misconceptions that,...

While some might still be focused on SDN with an OpenFlow-style twist, 30% of the organizations in our survey this summer (report forth coming, I promise!) were looking at SDN to improve time to market. Of those, 73% considered an API-enabled infrastructure to be important to very impo...

Every day and every second, the system administrator gets tones of information on the network operation, network devices’ operation, and messages from users; he sets dozens of challenges, which must help to avoid the existing and possible problems in the future. Often, it is rather dif...
Silver shows that predictions in areas such as economics have been less successful, e.g. he examines why many economists missed the recession, and why supposedly expert forecasters get election predictions wrong so often. For example, before the recession of 2008, the assumption was ma...
You can then easily piece together full transaction traces by ordering all method calls by sequence number. Further analysis can be applied to this information for a number of purposes. For example, by analysing the transactions, developers can easily construct design diagrams that can...
More and more Web sites and applications are being moved from Apache to nginx. While Apache is still the number one HTTP server with more than 60% on active Web sites, nginx has now taken over the 2nd place in the ranking and relegated Microsoft’s IIS to 3rd place. Among the top 10.000...
Some time ago I blogged that Java Swing should be deprecated and replaced with JavaFX. In this blog I’ll show a piece of JavaFX namely event handlers and binding. I’ve created a simple Sign In window with a GridPane layout (it’s JavaFX equivalent of Swing’s GridBagLayout). I’m not goin...
We often get asked “Should I use GridFS for file storage with MongoDB”. As with most things, the answer is a staunch “it depends”. GridFS looks like a great idea on paper - a virtual filesystem held within MongoDB which allows for larger than 16MB files to be held, synced and replicat...
The supply chain is evolving, and buyers need to analyze and predict, but also to manage risk. When Capgemini's business information management (BIM) practices unit needed to provide big data capabilities to its insurance company customers, it needed to deliver the right information t...
Some people believe good or bad things always happen in threes. I believe you will always be able to find three (and probably more) things that are good or bad and somewhat related, but sometimes I get surprised by the apparent coincidental appearance of several closely related “things...
