I use Vagrant with VVV extensively for setting up local development environments and have a couple of Vagrant boxes setup in my mac.
Recently I was running out of disk space in my Mac which prompted me to look around to see if there are any unnecessary files that can be cleaned up.
This let me to find out that Vagrant stores all versions of boxes that were downloaded even after upgrading them.

I use the Mac Terminal App a lot to ssh into remote servers. It all works great except for a single annoyance. If I leave the ssh tab open without any activity for sometime or put my Mac to sleep, then the tab gets frozen and becomes unresponsive. It takes a couple of minutes for it to log out of the server and become responsive again, so that I can reuse the tab again.
Whenever this happens, I have to close the unresponsive tab and open a new one, or wait for 5-10 minutes. I did some research about it and found that Mac Terminal App provides an escape command that can be used to forcefully log out of the remote server. All you need to do is to type the following command in the unresponsive tab.
~.

I tried it and it works like a charm. It immediately logs you out of the frozen ssh tab and you can reuse your tab again without waiting for it to become responsive again.
Hope this small trick is useful for others as well 🙂

Recently, I switched to a new Mac Retina (one of the numerous perks of working at Yahoo 😉 ) and wanted to install OpenCV in it using Homebrew.
I ran the usual brew install opencv command and got No available formula for opencv error message. I have personally ran this command before to install OpenCV and was wondering what went wrong.
After a couple of web searches and ‘hair tearing’, I found that the opencv formula has moved to homebrew-science and I had to do the following.
brew tap homebrew/science
brew install opencv
Finally everything worked. So even if you are facing the same problem, then you know what to do now (and possibly save some hair as well) 🙂
Oh, by the way, if you own a Mac and don’t know what Homebrew is, then stop everything and install it right away. You can thank me later 😉
