I got an email today from a hashr user complaining that the add-on was not working on Firefox 3.5. I had noticed it a few days ago, but completely forgot about it.

I’m currently updating the add-on to 3.5, improving the user interface and maybe add some new feature. But for now if you wish to use the extension with Firefox 3.5 you can use a little hack that works with no problems.

Just locate your Firefox profile folder, and then open the extensions folder inside it. There will be one folder with the word “hashr” in the name. Open it an edit the file install.rdf.

Inside the file locate the following lines:

<em:minVersion>1.5</em:minVersion>
<em:maxVersion>3.0.*</em:maxVersion>

And change it to:

<em:minVersion>1.5</em:minVersion>
<em:maxVersion>3.5.*</em:maxVersion>

Save the file and restart Firefox. It should now be working perfectly. If not, check the add-ons manager to see if it’s disabled.

Edit: Mozilla has finally approved the new version of hashr, so this hack is no longer needed. You can find the addon here: https://addons.mozilla.org/en-US/firefox/addon/8539.

If you use the terminal in OS X allot, you have probably noticed that the ls command has no colors. You can activate the colors by adding the following to your ~/.profile:

alias ls='ls -G'

Or you can even choose a better way. Adding the following to your ~/.profile:

export CLICOLOR=1

Now you just need to restart your terminal, and you have a all nice and shiny ls output.

The problem is… if you use a dark background, like any other sane person. The dark blue coloring the directories names is simply impossible to read.

To change that color you just need to add another line in your ~/.profile file:

export LSCOLORS=gxfxcxdxbxegedabagacad

What’s with the DNA chain? Well, it’s just some crazy way to configure the ls output color. You can find the corresponding color to every character on the ls man pages. Just to keep it simple, that combo turns the directory names to cyan, so that they become readable on top of dark backgrounds.
