Ceci n'est pas une pipe

While the voice phlegmatically Lombard Maroni said the people of the night where and how Saviano was wrong, I try to post to WordPress from my BlackBerry, yet to see if it works or should I resign myself to the iPhone - which I personally hate ...

I have been reporting that in many, returned from lunch, they noticed the glaring absence from the network of their favorite pastime. I confirm that FaceBook is down for some, as documented in this link . Found out that it was not their problem, and capiufficio owners have enjoyed the unexpected shot in the arm: today the productivity of their companies will return to acceptable levels. But I pointed out to them that if they want to permanently obscure FaceBook and the like on the workstations of employees of solutions there is more than one, not to buy one of our firewall with content filtering. If not us who are we doing?

The last four of the six immigrants for over two weeks have been holed up on a crane in San Faustino in Brescia are finally down. I was impressed to see them suspended for a day, framed by cameras, which sharpened their expensive optics to capture a facial expression or detail of a dress worn. Images intended, among other things never go on the air, as only the local press has dealt seriously with this event - in my opinion epochal. I wonder if the rest of the country has not the faintest idea of ​​what is today the city of Brescia and the heady atmosphere that you breathe. Here is the story ahead of time anticipating at least ten years. Brescia is now a sort of anarchist laboratory, now what is happening here happens everywhere in the coming years. Seen from here the integration seems to require a slow revolution, a sort of controlled explosion and far from violent, perhaps with the usual tears of every major change, which tears from time to time will hurt someone - it is inevitable - but not more willing to look at things for what they are. If you walk the streets of this in a way that is my home town you hear that an old, tired balance is shifting slowly but resolutely, without breaking. Brescia I like and trust a lot in this city, let's see now what happens.

Today happened to me one of those things that is nice to say only when they are finished. I was arranging a series of new virtual host web server on a client when, quite suddenly, the machine has stopped responding to any form of control. The bash environment where I was typing my commands seemed intact, in the sense that I could make any normal operation unless they had something to do with the filesystem worked perfectly as top and ps commands, but it was impossible to make the less of a files or even get the man of any command ... In all cases I obtained a brutal and unequivocal Input / output error, sadly obvious symptom of a problem on the filesystem.

Not that it's a situation where I found myself often, thank goodness, but being almost certainly a problem with the RAID controller and not discs (both brand new) I decided to do a reboot, but this command returned the same error: not being available in memory in the form of the kernel process must necessarily be taken from the filesystem, so ... Input / output error.

With the introduction of this novel and boring, hard to come here and register the pair of commands with which I was able to tell the kernel my bad intentions:

# echo 1 > /proc/sys/kernel/sysrq
# echo b > /proc/sysrq-trigger

With the first statement I have sysrq enabled the flag that allows you to send commands directly to the kernel, while the second statement is in effect a command to reboot. Here are some useful links to learn more about this powerful and valuable mode of interaction with the Linux kernel:
