I have been writing Ruby applications exclusively for awhile now, so I thought it is time to try out something new. As a result, I have developed an OSX Cocoa application for hallenprojekt.de, a website that aggregates different co working spaces. It is an application that lives in the status bar and allows easy checking into the available co working spaces.

It was fun and sometimes painful to learn how to achieve things with Objective-C and Cocoa in particular. And of course, learn how to automate packaging and deployment of new releases including automatic updates. Ironically, I ended up doing most of those tasks with Ruby. I will write a few blog posts covering my endeavors.

The source is available on github and the application itself can be downloaded here.

This is quick tip week. Have you ever wanted to preview a file on OSX with quick view without leaving the console. Well here is how:

qlmanage -p file

So if you wanted to preview the file image.png you would type:

qlmanage -p image.png

If you want to see the thumbnail preview of a file instead, just use -t instead of -p.
To close the window either click the cross on the upper right corner or hit control-c to cancel the process. Happy previewing!

Just in case you want to flush the DNS cache on an OSX system for whatever reason, this command gets the job done:

    dscacheutil -flushcache
