Fix for Firefox memory leak on Windows





This seems to help out with the memory usage quite a bit. Generally, when you minimize a window the memory usage goes way down because that application isn’t active. Unfortunately, Firefox by default doesn’t adhere to this behavior. Here’s how to force it to.

Type the following into your address bar in Firefox:

about:config


You will see a window that looks similar to this:

You will want to right click anywhere in the window, choose New, Boolean, and enter in the following text:

config.trim_on_minimize


To change the value you can either doubleclick, or right-click and choose Toggle. You will have to restart Firefox, but after you do, you should notice the memory usage go way down whenever you have Firefox minimized.

Update: You will want the value to be set to True in order for this to work.

30 Essential Pieces Of Free (and Open) Software for Windows

Recently, I received a fresh new laptop from Dell. Upon receiving it, I did the traditional “installation of Windows from scratch” on it to remove a lot of the garbage that is preinstalled on Dells. Then I got really busy installing tons of great software that takes care of pretty much every software need I have. Not only was all of the software free, every piece of it was open source, which means that the code is peer-reviewed; no spyware here!

What follows is a list of thirty pieces of software that are the cream of the crop of open source software for Windows. Not only is every piece of it free, almost all of them directly replace expensive software packages.

Super-Close Google Maps Zooms

Wow!

Super-Close Google Maps Zooms

Holy moly that is a close up zoom of a camel (see my screenshot above) – and it works for other place on Google Maps too! Yes, it turns out that you can zoom in much more deeply onto Google Maps by doing this:


  1. Select a location and switch to satellite view

  2. Zoom in as far as you can, and click “link to this page” at the top right

  3. Now replace the “z” parameter in the URL with a higher value, e.g. 20, 22, or 23, and wait. Some locations will now show more detailed imagery

The French Ecrans website and Geotrotter have more on this.

What fun images can you find? Please post screenshots.

Playing water ping pong.
It seems he’s looking into the camera, actually.
This is a rare zoom level 23, almost (already?) creating privacy issues people joked about earlier.
Nobody’s in the Googleplex pool.


Relaxing at the beach.
