A furin that doesn't need wind to chime

Do you know the furin?

It is an ornamental bell very popular in Japan, usually made of glass, with a clapper attached to a strip of cardboard. When the wind blows you hear a relaxing "ding-ding-ding."

But what if we want to place it in our room, or in other windless places?

That's easy, there is the electronic furin:

The most useful Firefox extensions

Although now my usage of Firefox is in sharp decline, thanks to the thousands of extensions available, there is always a moment when it becomes necessary.

These ones are the most useful, in my opinion:

  • Clean and close - Allows you to delete completed downloads and close the Downloads window with a single click
  • Deng Google Bookmarks - Inserts a bookmark menu to access Google Bookmarks. Definitely useful if you use more than one computer and don't like Firefox Sync
  • DownThemAll - The best download manager for Firefox!
  • Lazarus - A must! In the event that the browser crashes or the web page has a timeout error while you're filling out a form, you can open it and fill it again with one click! Cool!
  • IE Tab - Allows you to open the page with one click using Internet Explorer. The original link does not work anymore in the latest Firefox (5 versions in the last year!), There are several clones, one is an adware, but the best one is IE Tab 2
  • Rikaichan - A great extension that allows us to know the meaning and the reading of Japanese words unknown to us (Also install the dictionaries - You need to know the hiragana)
  • Super Start - A start page inspired by Google Chrome
For advanced users avanzati:
  • Aging Tabs - Change the color of the less used tabs, it is very nice, too bad it does not work in the latest versions of Firefox...
  • Ghostery - Blocks tracking scripts
  • Gmail Manager - If you have many, too many gmail accounts, by using this extension you can manage them all without too many worries
  • Greasemonkey - Allows you to change the behavior / appearance of some websites by downloading the appropriate script from userscripts.org
  • NoScript - Blocks all the javascripts except those authorized by you, for added security - Use only if you are paranoid - many sites will not function as well as before
  • Springpad - For adding notes to any page - terribly useful and productive
  • WiseStamp - For adding a custom signature to Gmail emails
For web designers:
  • Colorzilla - For seeing the color of any object on the page
  • FireFTP - One of the best FTP client I've ever tried! The integration with Firefox is great!
  • Firebug - All-in-one tool for development
  • Measureit - For measuring the elements of a page in pixels, is more useful than you can think
  • Screenshot Pimp - To make a screenshot of an entire page, even the parts that aren't visible. WARNING - It's a very invasive adware - install only when necessary and then immediately remove
  • Qute - A very balanced skin that adapts to each operating system. Too bad that is no longer compatible with new versions of Firefox ...


Forward ports in VMware Server

Fortuitously, today I found a note that some years ago I marked as "critical", so here I am to share it with those who might need it one day

When nearly four years ago I moved Serverland from a virtual server to a real one, I thought that it was a good idea to continue to be virtualized, so I installed VMWare Server (it's free!).

Then, the shockingly low performance in accessing the virtual disks, led me to uninstall it, but at the time I had a problem: in the Windows version of VMware Server, there is a convenient panel for configuring the virtual network, but in linux version is absent ... what we can do?

The answer is here: http://www.howforge.com/port-forward-in-vmware-server-for-linux

How to delete files older than X days on linux

Sometimes can happen that you want to keep only the files of the last X days in a directory.

On Linux you can do that with a single command line:

find /path/where-are-the/files* -mtime +7 -exec rm {} \;

How it works:

-mtime indicates the days to keep. In the example, having written +7, we only keep files from the last week.

-exec indicates the command to execute in the event that a match is found (ie: the files older than a week), and in this case we pass rm, which eliminates them

Reverse DNS lookup (rDNS)

Have you ever wanted to know which URL belongs to an ip address? For example, what is the URL of the Google public DNS service,

To overcome to this problem I wrote a program to do the reverse DNS lookup (rDNS), of a given IP address, here it is:

For example, looking, you get google-public-dns-a.google.com

How to configure a GPRS connection with China Mobile

When I go to China, I always buy a prepaid sim card with an Internet subscription. The card is free, although almost every seller will attempt to scam you by telling that now costs 20 euros (do not buy it from them out of desperation, on those pre-activated, you can not enable internet subscriptions with immediate effect but only after a month!! Go in 10-20 different stores until you find an honest seller, or the best way is to go to a China Mobile official store, but be careful to the fake ones), and with 5 euros per month you can get a 500 megabytes package, that with GPRS, it's enough for everyone. (Western phones won't support Chinese 3G - you are left with 2G)

There is also a way to spend less, but you have to use a wap proxy to access the web - a nightmare - don't save money on this

Once purchased the sim, your Western phone won't be preconfigured for internet access, so here it is:

China Mobile Web:
apn: cmnet

yes, just put cmnet as APN and voila, you can access the internet! You don't have to configure the WAP, because it only works on Chinese sites.

Then you can also configure the MMS, if you have Chinese friends and you plan to receive them:

China Mobile mms:
apn: cmwap
mmsc: http://mmsc.monternet.com
mms proxy:
apn type: mms

How to convert audio/video files without download any program

Sometimes we find ourselves using computers where we can not install programs, like a public computer, such as school or library, or computer in the workplace.

But, sometimes happens that I want to convert an audio or video file at work, but I can not install a converter... how can I do?

Mediaconverter.org is an online service that allows you to upload audio/video files and convert them.

It's free (freemium), and is very convenient. Of course, for the most demanding users who wants to convert large high-definition is not really suitable, but is perfect for small uses.

Firefox 9 is out!

Breaking news, Firefox 9 is out!
There are huge improvements, as the... uh.... ehm.... er... well, if it has a new number there's certainly something new!
Maybe for the end of the year they can manage to release Firefox 15.

Avast is even more ridiculous!

Not long ago I wrote that AVG was ridiculous because it deleted every file that contained the string Førmat c: /autotest /q /u (I replaced the o with ø for a reason that you'll see later).
Today, after the fifth time that AVG would interrupt me while I was playing GTA IV for letting me know that it found some false positives, like SafeXP, the Office 2010 keygen and others, I decided to replace it with Avast.
Um, great, it looks great, I tell myself.
I'm going to write the result on dandandin and...

I got shocked! My server infected?? Then, I realize that Avast blocks the access to any website that contains Førmat c: /autotest /q /u!!!!!!!!!
WEIRD !!!!!!!!!!!!!!!!!!!!!!!111 !!!!!1111!1!1!1
This was my reaction:

Have you seen my nutcracker?

Tsk! A nutcracker is for losers, I'll show you how to open a walnut with hands...
