http://blog.geeksgonemad.com/2013_12_01_archive.html
In the current age of internet speed, you can't scale a company without having Dev and Ops close together. In older, or more established organizations, the transition to a Devops mentality has many challenges. Here are my thought on Devops from the perspective of an established organization migrating to Devops. Tuesday, December 17, 2013. Logstash Metrics Filter and Graphite Output. If [type] = "apicalls" { mutate { add field = [ "modhost", "%{host}" ] add field = [ "modorgname", "%{org name}" ] } mutate...

Monday, 30 September 2013. Revoking private key access to EC2 instances, and other random tips. Consider the following scenario. You have many EC2 instances running production code. Access to those instances is using a passphrase-protected key. A member of your operations team who has access to the key leaves so you have to change the key. Or, you need to change the existing key as a matter of some internal security policy. How do you do it? Generate a new keypair. Done The old key is useless now. AWS ke...

code@deepinspace.net: gcc does not check out of scope names in unreachable code
http://code.deepinspace.net/2011/01/gcc-does-not-check-out-of-scope-names.html

While attempting to write a small HTTP server in C, I copied some code over from a previously written C file and immediately noticed a bug. Include "./mynet.h". If(errno = EINTR) {. Yes it's a stupid beginner mistake - typing the assignment operator instead of the equals check. The thread of execution would never enter the else block. I corrected it, but the interesting part came when I tried to compile it. I would say ye...

Monday, 1 March 2010. I finished reading Dreaming in Code. Last week. It's Scott Rosenberg's account of a software development team's effort to build the ultimate Personal Information Manager (PIM). Led and funded by Mitch Kapor of Lotus 1-2-3 fame, the team goes through endless cycles of redesign, people issues and other upheavals. Rosenberg follows the team very closely, participating in their meetings, interviewing them and filling the narrative with his own insights. Due to numerous reasons, Chandler...

The abyss between dev and ops. This blog is about topics affecting developers and sysadmins. The application is only running on the developer system. On Thursday, March 25, 2010. As communication always two-sided, so is this problem. There can be different sources:. The admin has changed a default value of a configuration. The developer has changed some classes and now needs other permissions or files. The admin has installed an update and the application is installed on this test system. In a perfect wo...

The abyss between dev and ops: New versions of Selenium
http://devops-abyss.blogspot.com/2011/07/new-versions-of-selenium.html
The abyss between dev and ops. This blog is about topics affecting developers and sysadmins. New versions of Selenium. On Wednesday, July 27, 2011. I'm aware Selenium 2.2 is out. I hadn't had the time to verify my check with this new version. A user gave me the feedback, the check is working with version 2.0. So hopefully it will also work with the newer versions. I'll try to get my hands on the new version as soon as possible. New versions of Selenium. Devops and sysadmin blogs.
