Firefox - Remove slow and wave effect from high resolution monitors

I am using laptop (with no special graphics card, but only inbuilt) and extending it to external monitor. The external monitor is high contrast and supports upto 1920 x 1080 (full HD) resolution. When Mozilla Firefox is opened in this high definition Monitor, it becomes very slow and wavy.  The dragging effect is too much and discourages from using Firefox !! A solution to this is to "Disable Hardware Acceleration" within Firefox settings. To do this Firefox -> Tools -> Options -> Advanced -> General Remove the "tick"  from (Uncheck) "Use Hardware Acceleration when available" Firefox fix has been tested on Samsung SyncMaster BX2240,  Syncmaster 2443 monitors  Advanced Users about:config   -> layers.acceleration.disabled  -> change value to " true "

Keepass Password Safe - Bulk Actions using field references

Keepass password vault and the simplicity of the tool are essential if your day to day work. But I always encountered problem when it came to bulk actions; especially when passwords were the same for a set of servers (group) Bulk Actions on Keepass To do bulk actions (mass batch changes) , it is always advisable to have your list organized into groups.

ssh equivalent of telnet

We will look into a method to do ssh equivalent for telnet You guys must be familiar with running SSH. Using Standardport it would be ssh <serverIP> If you want to run ssh on a non-standard port it is ssh -p <portNumber> <serverIp>     #eg    ssh -p 5443   10.112.12.13 But recently many Admins started removing "telnet" from *NIX machines. Previously Telnet was used to check if the remote machine was listening to a port and the connectivity. We used telnet as below telnet <serverIP> <portNumber>  #eg   telnet  10.112.12.13 5443 You could simulate telnet using ssh command line. Though SSH is a protocol and not a debug tool, we could do some tricks.The equivalent of above telnet would be ssh -vv -p 5443  10.112.12.13 ssh -p <portNumber> <serverIp>  telnet <serverIP> <portNumber> ssh -vv -p 5443  10.112.12.13
