To get a better handle on Erlang’s behavior, I decided to install a popular set of tools for debugging and performance profiling: EPER. I think it stands for “Erlang PERformance tools”, but it could also mean “Everything Proves Erlang Rules” or “Egrets Prefer to Eat Robots” or really anything for that matter. One thing is for certain, however: getting these tools built and running on Mac OS X was fraught with danger and build errors.
I am always writing small tools to help me out on a daily basis. Sometimes shell scripts, but
other times I want something a bit more complex. When I need more than a simple shell script, I like to leverage ruby for its vast library of gems which can greatly accelerate and simplify the task of building these helpful tools.
This post will give an introduction to writing your own CLI tools in ruby and packaging them
as a gem.
For years developers (and consequently consumers), have had to accept the fact that the Tablets (and some phones) would always have the System/Navigation Bar visible on their screens. A 10.1 inch advertised screens, offered in fact a 9.8 inch usable screen.
Finally Google’s latest Android OS, KitKat, introduces a decent user-friendly tool that gives us ownership of that last bit of screen.
Let’s face it, creating web graphics takes time and is often tedious, especially if you have to slice images from detailed web page layouts. Sometimes it’s even necessary to copy and paste graphics from a Photoshop layout into a new Photoshop document just so you can isolate graphics and save for web. Recently I began experimenting with creating web graphics automatically from Photoshop layers using the new Adobe Generator feature, which was released in Photoshop CC version 14.1 (to check your version launch Photoshop and go to the menu and select Photoshop/About Photoshop and this will open a panel that includes the version number). When Generator is turned on it will monitor the file you’re working on and generate web graphics based on how you name layers. The cool thing is that as you continue to work in Photoshop and make changes Generator will automatically update assets.
