Reseting DNS cache in Windows, Mac OS X and Linux

It can be quite annoying if you have attempted to connect to a website and it is unreachable as windows remembers unresolved DNS requests. This can mean that the next time you attempt to connect to the site it fails even if the site is back up and running. This can also be a problem if you are trying to connect to other services such as FTP.

Windows Users

In Windows enter the command prompt – Start Menu >> Run type in cmd and hit enter. Enter ipconfig /flushdns at the command prompt as below as hit return

C:Documents and SettingsYour Name>ipconfig /flushdns
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

Mac OS X Users

If you using Mac OS X then open the terminal and enter the following
OS X <= 10.5.1
lookupd -flushcache
OS X >= 10.5.2

Linux Users

Linus users open up the terminal and enter the following
$ sudo /etc/init.d/nscd restart

or

$ service nscd restart

Google Street View UK Goes Live

Google launched street view for the UK on Thursday March 19th showing detailed street level images from 25 of Britain’s cities. The following cities have been closely photographed-

  • Aberdeen
  • Belfast
  • Birmingham
  • Bradford
  • Bristol
  • Cambridge
  • Cardiff
  • Coventry
  • Derby
  • Dundee
  • Edinburgh
  • Glasgow
  • Leeds
  • Liverpool
  • London
  • Oxford
  • Manchester
  • Newcastle
  • Norwich
  • Nottingham
  • Scunthorpe
  • Sheffield
  • Southampton
  • Swansea
  • York

This image of Cardiff Castle shows just how much detail that has been captured by Google’s menacing looking Black Opels driving along our streets. The worrying thing about this is peoples privacy. Google has assured everyone that their software will automatically blur peoples faces but this unfortunately simply is not true.

Out of curiosity I was having a ‘drive’ around my local suburb of Cardiff only to discover that many people’s faces have not been hidden as promised. Worse still there is a mother walking down one street with two kids, one of which can be identified. Now I don’t mind if I could be identified if I was snapped walking down the street but children? Come on Google sort it out.
