This is just a short reminder for me and a note for you on how to write a valid XHTML strict snippet to insert a YouTube video.
<p>
<object id="video_o" type="application/x-shockwave-flash" data="http://www.youtube.com/v/JaJbDln7oGA" width="560" height="340">
<param id="video_p" name="movie" value="http://www.youtube.com/v/JaJbDln7oGA" /><img src="http://www.youtube.com/v/JaJbDln7oGA" width="560" height="340" alt="titolo_video" />

I’ve bought a Iomega Storcenter ix2 which should be a 1 TB NAS and even though it offers a good list of features, I’m sorry to say that I’m quite disappointed with it.
- In the previous sentence, I wrote “should be” rather than “is” because its interface shows a warning like “second disk missing” so it lets me use just 500 MB (no second disk, no RAID): I still haven’t opened it so the second disk might be there but in this case I couldn’t understand the reason to show such a message;
- another disappointing message is something like “no UPS, no low power mode”: it’s displayed even though I connected it to a real UPS (I don’t know what it needs to recognize that it is powered through a UPS: a USB link, perhaps?);
- on its website, it was stated that it is able to “copy or backup files to and from (…) any other NAS” but I wasn’t able to program it for this task: it can backup and sync even on schedule from NAS to NAS but only saving and running the task from a PC.
A QNAP TS-219P might have been a better choice (a little more expensive, though).

(This should be a crosspost written with Massimiliano)
It seems that MarkerClusterer has a bug, fixed with this patch (*) written by Massimiliano while we were hunting together for it on this application (now working fine): after the ajax submit and zooming out, the library was still displaying old clusters and markers, because, after destroying MarkerClusterer, the event assigned to GEvent wasn’t correctly removed.
(*) the patch is created against the r1159 version on gmaps-utility-library-dev.

Often I have to use my Huawei E176 (which I previously described) inside an area not so well covered by HSDPA signal: in order to increase the bandwith I can use, I bought a 5 dBi GPRS/UMTS antenna.

Does it work well? Answering is measuring. :)
Thanks to the very good list of AT commands written by Fredrik Lindberg, I was able to determine the power increase of the received signal: passing a simple AT+CSQ to my modem through Minicom, I got a number in the RSSI scale.
The sequence to convert it to Watt is:
dBm = (RSSI * 2) - 113
W = (10 ^ (x / 10)) / 1000
For example, without the antenna, one of the RSSI values I got with AT commands was 3.99, while with the antenna it increased to 8.99, so:
3.99 RSSI => -105,02 dBm => 3.14 * 10 ^ -14 W
8.99 RSSI => - 95,02 dBm => 3.14 * 10 ^ -13 W
The power of the signal received by the system with the antenna was ten times greater than without it.

Pare che fino a pochi secoli fa, la Pianura Padana equivalesse a circa un terzo della terra fertile afferente al Mediterraneo: non sono in grado di riportare un riferimento bibliografico ma non mi sembra un dato inverosimile.

Potrei aggiungere molte cose ma sarebbero meno importanti delle seguenti azioni minime:

Google describes the private browsing feature of Chrome as something useful
(…) for times when you want to (…) plan surprises like gifts or birthdays
Was this feature conceived to help the average user to hide their e-commerce browsing history? I really don’t think so. Their informal motto is “don’t be evil“: I’d change it to “don’t be either evil or hypocritical”. :-)

Having registered this website on the Blog Action Day, I’ll try to write here some notes about climate change.
On their website, it’s stated that
(Climate change) threatens to cause famine, flooding, war, and millions of refugees.
Even though it is undoubtedly true, I’m still persuaded that it’s only a consequence of the deep faith a large part of humanity has in unlimited growth.
It’s sad but there are people truly concerned with climate change who think “let’s fix it so we could quietly continue to grow as usual”… they really miss the point: holding this old paradigm leads us to problems harder than climate change itself. We would have to move on even if this problem didn’t exist. Unfortunately, the revolution needed to make such a transformation possible is very hard to realize, therefore it is very unlikely we would be able to avoid several hundred million deaths in the following decades.
Although the internet has plenty of good suggestions to follow, I can’t give you a hint for some real actions to avoid this scenario: just don’t forget what Prof. Edsger Wybe Dijkstra once said:
Do only what only you can do.

L’accordo con Andrea era di non scriverne fino alla pubblicazione, che ora grazie a Stefano scopro essere avvenuta. È quindi uscito il volume “Il software libero in Italia“, al quale ho contribuito con la prima stesura del capitolo sull’Italian Linux Society e knopILS.

As I’ve previously stated, joining social network groups won’t turn you into an activist: it’s definitely not enough even to save your own conscience! You need to call into question the three main things you have: time, money and reputation; so please, don’t invite me to join or subscribe to any more groups of that kind. The 2.0 gears may be helpful but standing up actually is still essential.
