Access Linux Filesystems In Windows Using Linux Reader

Earlier today, I had to access my HDD in Windows 7 through USB bridge which I had been using as an internal hard disk for my laptop but unfortunately it didn't. A quick googling revealed a very useful tool by Diskinternals.

Linux Reader is a free software from Diskinternals which excel in building recovery software solutions. Linux reader supports several filesystems used by Linux OS. Below is the list of supported filesystems:

• Ext2/3/4
• ReiserFS, Reiser4
• HFS, HFS+
• FAT, exFAT
• NTFS, ReFS
• UFS2

The program provides for read-only access and does not allow you to make records in file system partitions. This guarantees that the interference in an alterative file system will not affect the work of Linux later. Apart from this, it is necessary to note, that it gives you an opportunity to use common Windows Explorer for extracting data. A preview option for pictures is one more pleasant point, which is worth mentioning. While saving, it ignores file security policies. It means that it is possible to access absolutely any file on a Linux disk from Windows.

How To Enable SPDY 3 In Firefox 15

Firefox 15 now supports version 3 of SPDY, an open networking protocol designed to reduce latency of web pages but is not turned on by default. This post will provide the instruction to enable SPDY 3.

Type in address bar, about:config and then search for spdy. Now you will see a particular preference name network.http.spdy.enabled.v3 which is by default set to false.

All you have to do is double click on that preference name to change its value to true. This will enable version 3 of SPDY in your firefox 15.

Note that SPDY v3 will bring support for flow control, update the compression dictionary, and remove wasted space from certain frames, along with other minor bug fixes.

Also, note that the version 3 of SPDY is included for the first time in firefox 15 and might not be fully stable.

How To Automatically Start Firefox In Private Browsing Mode

In this post, I will provide the instructions for few of the methods to automatically start firefox in private browsing mode.

Method 1

Go to Edit -> Preferences and then select the Privacy tab. From the History dropdown list, choose the Firefox will Use custom settings for history and then check the Always use the private browsing mode option.

Method 2

The second method involves changing the firefox configuration which can be accessed by typing about:config in the address bar. The first method described above essentially changes one particular preference name browser.privatebrowsing.autostart in background and this second method involves doing that background job manually on our own.

Once you open about:config configuration page, search for private and from the resulting list, modify the boolean value of browser.privatebrowsing.autostart to true by double clicking on it.

I hope this helps. If you got any other method, please drop it as a comment. :)
