By writing we carefully sift through our own thought processes to break it down for novices, or a broader audience. This is a learning process for us, too. It’s therapeutic. But it also hones our message and makes us better teachers. We literally learn by doing.
Doing code reviews is a great way to discover things that people might struggle to comprehend. While proof-reading OpenStack patches recently, I spotted that people were not correctly using the various decorators Python provides for methods. So, here's my attempt at providing me with a link to send in my next code reviews. :-)
Yes, there is an “Ops” role for your product. Understand who that is. Consider, for example, what problems an app store solves. Developers must cater to anyone between them and the end user. Any part of an upgrade that could be automated should be.
After a particularly horrendous streak of failures, I sent a team email saying, "Guys, the build is all screwed up and we need to fix it immediately. If you fix the build, I'll buy you doughnuts." You know what happened next? Someone fixed the build within the hour.
Maybe you want to learn shell scripting, but you need to get work done now that you don’t yet know how to do. One of these strategies could buy you some time.
A difficult-to-test scenario are asynchronous processes. If a method-under-test has threading, getting the timing right for the testcase asserts is difficult. Typically, the method will return control to the test class prior to competing the logic that is being tested. The test class then immediately starts processing the asserts. These tests are flaky at best or completely broken at worst.
Aaron and Brian talk with Brian McCallion about real-life usage of AWS, the AWS services model, the new application development model and how enterprises are leveraging public cloud for competitive advantages.
For the uninitiated, Kaizen is a Japanese word meaning "change for the better" or "improvement." The two parts of the word, which are displayed in the picture, translate into "change" and "good."
Yesterday, the big web news story of the day was the NYT outage. But the bigger performance story of the day was not the fact the NYT was down for a few hours, but rather, how the NYT team did all the right things to handle the outage.
Following our events earlier this year in Raleigh, Montevideo, Buenos Aires, Toronto and Portland, we bring Percona University to Washington, D.C. on September 12.
In today’s edition of our blog series, “VMware or Microsoft?”, my friend Keith Mayer describes how you can use Windows Server 2012 as your storage servers for clustered NFS storage.
SaltStack is often boxed into the configuration management tools basket, but it's much different from most software like it. In fact, it is radically different than most configuration management tools.
Logentries agent enables users to get set up very quickly. We provide it for convenience as using the agent is far easier than configuring similar tools like syslogs.
Deployment Automation replaces the manual non-standard deployment process to standardized automated deployment process for various environments such as Production, QA etc.
Our team is currently running a blog series to demystify some of the misinformation, rumors, etc that exist in the market today concerning ESX versus Hyper-V.
Unfortunately malicious intrusions are a part of life. Products such as Tripwire do a great job of keeping an eye on your file integrity, but what about package integrity?
Git is now my favorite version control system. Git and GitHub are very powerful, it has (nearly) all features I can think about, and best of all: As a distributed version control system, I can work with it, even if disconnected from the network.
Today, software innovation is shifting from not just writing the code but also to delivering it to customers with faster time-to-market with high quality.
Tim Spann assembles a collection of resources on Cucumber and BDD.
At some point in time, a Ruby developer realized the need to serve gems within a private network. The main reasons why...
Facelets is an open source web template system under the Apache License. JavaServer Faces 2.2(JSR 344), is a part of JavaEE 7 specification, defined Resource Library Contracts which enables reusing Facelets templates in entire application dynamically at runtime.
I’ve been working in C++ for a few months now – after three years we’ve been apart.
I always amazes me how simple things I took for granted do not exist (at least not out of the box) in C++, one of which are reflection.
If you do not know what Beaker is, the Architecture guide is a good start...
Recently in a project a method was altered from private to be public. The functionality that was used only inside the class was needed from outside and the without any other change the method got into the interface the class implemented and the keyword private was changed to public. To do that this was a task.
As I am learning, experimenting and playing around Lean Startups, Design thinking and Innovation, this book Brick by Brick, How LEGO rewrote the rules of innovation and conquered the toy industry provided additional evidence to support my thinking around innovation and creativity.
