From OpsCode, a thirty-minute tale on the triumphs and hurdles Turner Broadcasting System's team encountered as it attempted to implement DevOps and deploy Chef.
At an insurance company, I encountered an application that had been in place for thirty years. Classic flat-file, mainframe COBOL. And decades old. It had never been replaced with a packaged solution. It had never been converted to a SQL database. It had never been rewritten in VB to run on a desktop.
I recently refactored some code that takes longs from two different sources to compute one value. The code originally stored the longs and called a function when all of the data arrived. The refactored version partials the data while it's incomplete and executes the partial'd function when all of the data is available.
Dogfooding is a great idea, but it’s no substitute for usability testing. I get the impression that some products, if they’re tested at all, are tested by developers intimately familiar with how they’re intended to be used.
Grails has great support for testing. We can unit test controllers, taglibs, services and much more. One of the things we can unit test are views and templates.
New Augmented Search technology for log data is now available, built to help developers and testers understand application data faster. The idea is to add auto generated intelligence layers based on user search context.
The Mikado Method is a process for surfacing the dependencies in a codebase so that you can systematically eliminate technical debt. It gets its name from a simple game commonly known as “pick-up sticks,” in which you try to remove the Mikado stick without disturbing the others.
There have always, it seems, been people for whom attribution and citation really matter. Some of them passionately engage in arguments that last months or years, debating the merits of comma placement in written citations for the work of others. Bizarre, right?
We tried a new retrospective prioritization/voting technique this week that worked really well. After we had generated and discussed all of our ideas for improvement, it was clear to me that there were several excellent ideas and it would be hard to use our regular voting technique to single out one or two.
If you have been bitten by the process bug, like me, then you always see parallels between business, process, and everyday life.
If the ALT+F templates show poor IT Operations performance, the next steps in the Adapt and Plan phases are to identify optimal targets to achieve operational excellence and best-in-class status and then to set the stage for an Agile and Lean transformation strategy that should be executed on two levels...
The Grails team is extremely pleased to announce the releases of Grails 2.1.5 and 2.2.2 and 2.3 M1.
Panelists from Puppet, Chef, and DevStack discuss DevOps strategies in this panel from HP Cloud.
Aaron talks with Bart Copeland (CEO - ActiveState) and John Wetherall (Developer Evangelist at ActiveState) about how developers are adopting DevOps models and how polyglot PaaS technologies are getting deployed in the enterprise.
One of my recent innocent tweet about Gerrit vs Github triggered much more reponses and debate that I expected it to. I realize that it might be worth explaining a bit what I meant, in a text longer than 140 characters.
I’ve been in the IT industry for almost 8 years working in 4 different companies. During this time I had a chance to work with a couple dozen programmers, some of them successfully developing their career, some satisfied and staying in one place, and some fired.
This weekend I discovered a trick. I was at a friend’s place and as I was editing in the kitchen I realized that the chairs are terrible and the table is the wrong height.
Someone came up to me after my MAX session on web development debugging and asked for some advice on how to 'sell' unit testing to his clients.
Sublime Text is a very powerful and popular text editor. But it’s more than a text editor… it’s an ecosystem of programmer’s tools where you can go to armory and choose the winning set for every code you’ll face.
This five minute talk from DevOps Days Austin 2013 compares a week in the life of a DevOps team to that of a traditional IT Ops team, drawing on ZeroTurnaround's DevOps and IT Ops Productivity Report for this year.
Today: web apps on a floppy, the guts of Google Glass, Apache's Giraph hits 1.0, and four reasons to learn SQL, even if you really, really don't want to.
Let’s check out exactly what’s going on here and you really need video to understand the fatal flaw in the logic of SSL logos coming down over HTTPS.
Let’s explore how request queueing affects applications in the non-PaaS world and what you can do about it.
I recently typed out a long, thoughtful response in a textarea. I clicked submit, like I've done millions of times, and I got the dreaded "session expired" error message.
This week we're talking to Zemian Deng, a Java developer working for the Bank of New York Mellon.
