Ceci n'est pas une pipe

This week I spent a lot of my time renovating the Dell PE1950 server. It is not among the more powerful machine I have at my disposal but it is certainly a high quality server, designed to last much over time. One of my most urgent needs of the server when I make this level is the integration with Debian GNU / Linux software RAID-1 monitoring. A second controller mounted on the server you must install a special software and course set up properly the kernel. Often this type of operation requires much time and patience, especially in the benchmarking which must always precede the start of production of a server after such interventions. In this case it was all in the best way, I have to say more because of the quality of the controller and the software that used the distro (in the sense that in this case, Debian has no special merit in the proper functioning of the software).

I respond to a request for assistance that has reached me in the middle of the night: a server Debian GNU / Linux 4.0 (Etch) has been lost - for reasons that deserve serious study - the repository of public keys in / etc / apt / sources.list . list. This is - in a nutshell - GPG encryption keys are used to confirm the actual identity of the repository, to avoid downloading fake packets from some source.

The loss of public keys causes the error at each NO_PUBKEY apt-get update:

W: GPG error: http://security.debian.org etch/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY XXXXXXXXXXXXXXXX
W: GPG error: http://ftp.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY XXXXXXXXXXXXXXXX
W: You may want to run apt-get update to correct these problems

To resolve this problem, simply re-import the public keys:

gpg --keyserver subkeys.pgp.net --recv XXXXXXXXXXXXXXXX
gpg --export --armor XXXXXXXXXXXXXXXX | apt-key add -

It happens more often to receive bids from companies you never heard of that promise miraculous intervention of the first SEO, with almost immediate results and very attractive: increasing access to 500%, the presence in the front pages of major search engines for a not insignificant number of keywords, etc..

The experience and good knowledge of the subject make me immediately turn up their nose and takes only a few questions to put their backs to the wall the commercial - in the face of totally bogus results - expected to cash in on the EURO 1500.00. Unfortunately the same does not happen when talking to the same mall is one of my clients who, without bothering to consult me before, is convinced and signed a supply contract that is - bluntly - a downright scam.

The beach is not a good ally of electronic devices, more so than those who have sensitive mechanical parts such as the BlackBerry trackball.

After returning from a short vacation with my BB trackball seemed crazy: in a completely random it was impossible to move the cursor in any direction, mark rather indicative of the presence of one or more grains of sand between the trackball and microcylinders that transmit information movement of the pointer to the device.

After a brief googleata I found a post that explains how to disassemble and reassemble the trackball for a BB without doing damage. I'll point out it is really well done and I have been very useful:

The instructions and accompanying photographs are for the 8100 Pearl, but it turned out to be absolutely valid also for my 8310 and I think in general can be useful to anyone with a BB 8 *** series.

Sure some of you will ask, but what I'll do you bring to the beach? ...

Today the Cat Mammone has cazzabubbola. The return from the short break holiday has caught unprepared as ever and is now lying idle and devoid of natural enamel. Okay, an abrupt change of pace inevitably brings some trouble to anyone, but in your case I would say that things are going in a very bleak indeed. Flight urges Fabio and I can not make him accept the fact that its transmission is still preferred morning on vacation, while we break our back on VPN, CMS, DEM, SQL and DHL as well - for deliveries made to the address wrong. This post does not mean anything, it seems self-evident. We say that it is an experiment.
