Portable applications are programs that don’t require installation.  All the executables and libraries are placed in a folder of your choice.  Outside the system folder.  This can really save the day when you have computers that are locked down due to security policy and what you have can’t do the job.

James Anderson.

This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.

The first thing that got my attention is the reference to Western Union. I don’t use them, I have nothing to do them, they have nothing to do with me.  With my mental alarm bells ringing, it is no wonder Mr Anderson is not getting any money from me. Nigerian scam.

SSL anywhere.

SSL secured access for public websites are growing.  This has been mainly restricted to banking and finance due to the extra CPU computation required.  With the rise of more computer power and determined hackers, more and more websites are now offering SSL secured access for casual use.

The downside is that you have to type it out yourself eg httpS: or use a bookmark.

No longer.

A Firefox extension called HTTPS Everywhere is now available.  You checked the websites that you want SSL encryption and you are ready to go.  Or you can use the defaults, select all for websites eg. Facebook, Google Search, Wikipedia, NYTimes etc.

Note SSL is not a magic bullet to solve all web related security.  It is designed to secure web traffic between the server and the user computer.  It also prevents hackers from using the back button to resume a logged off session.  It does not prevent keyboard sniffers or trojans from sniffing your passwords.


A rare problem (hopefully).

This is something, one hopefully will never encounter.  A corrupted RAID  5 stripe.

RAID  5 works by storing data in logical stripes (64 or 128KB) with parity across the set of harddisks.  This is usually 3 to 6 disks.  If any of the disks were to fail, it can be replaced and data recreated from the parity bits.

It is also possible to have a corrupted logical stripe or punctured stripe as Dell calls it. This when the RAID controller does a hiccup. The only solution is to backup, wipe, re-create and restore.  Yes. Ouch.
