IPv6 - playing with the stuff

As I got my shiny new Cisco 877 router, I started playing (again) with IPv6.  Setting an IPv6-in-IPv4 to a Hurricane Electric was real easy.

Also, I started taking their tests and I got:

Google Chrome crashes on Fedora 15 when accessing a google document or calendar

I just had this: when opening a document in Google Docs or going to my calendar, Chrome would display the "Woops ..." page.

In /var/log/messages, a few lines point to SELinux:

I disabled SELinux and rebooted, no more crashes, proving its something with SELinux.

Prime Minister Cameron to go after social networks in UK

This is all over the press: prime minister Cameron told the parliament that it might be useful to disrupt the usage of social networks if they are used to plot violence, disorder and criminality.

This is a slippery slope: why attack the communication channel? Is Mr. Cameron planning to go after phones (might be used by criminals to communicate with each other), emails (frequently used to carry threats), or stop the postal services (has been used to send anthrax and suspicious packages)?

This story reeks the censorship, and given the events that happened in Egypt not long ago, Mr. Cameron should be very cautious in what he says: this could easily be perceived as the first step towards a police state or to a lessening of people's rights, more specifically of their right to free speech.

There are reasons why these people are in the streets. Is it the unemployment rate? Is it the increasing costs?   The growing proportion of household getting into debt?

Mr. Cameron should listen to the people and remember that there is more in a democracy than just elections.

Just finished reading - Schneier on Security

Schneier on Security Who doesn't know Bruce Schneier? Living legend in security, author, theorist, inventor or co-inventor of encryption algorithms (among others) ...

This book is a collection of articles and newsletters he wrote over a period of years, and approaches subjects as varied as cyberwarfare and cybercrime, the economics of Security and preconceived and false ideas in Security.

My main intake from it is: we get it wrong most of the time: the users, the politicians, the policy-makers, the medias. From emotional reactions to hastily passed decisions, there are numerous ways of misleading ourselves into thinking we're doing security, when we're actually window-dressing.

In summary, this was a nice reading, I really appreciated it, and I got many food for my own thoughts. Thanks Mr. Schneier, as usual: two thumbs up!
