    After some years of use, you’ll notice the increase noise coming from the cooling system. Any ventilator on the market, even the more expensive, or the more silent will wear off and start making noise. Replacing the ventilator is done in less than 2 minutes if you follow this little how to.

    Choosing the right ventilator

    • Don’t pay too much, better choose a cheap model and replace it every year or two
    • Below 19 dB, it is difficult to hear a ventilator running, don’t go over 22dB noise
    • You need a 80mm x 80mm x 25mm it is a standard size, you cant go wrong in a shop (other common size are 92mm and 120mm)
    • Check that the connector is a 3 pin Molex.
    • It need to run on 12volts, the lower the voltage, the lower the noise, but too low and the NAS may overheat since the air flow is also reduced.

    I paid this Xilence case fan 8 euros, sold as being silent 15dB, 1500 rpm, 18.67 CFM, not running below 7V.

    You can safely choose any brand:  Papst, Be quiet!, Revoltec, Zalman, Noctua, Noiseblocker, all of these are good if they meet the above requirement, unfortunately the were not available in my favorite shop (www.digitec.ch)

    Open the back side of your Synology NAS, remove the old case fan and replace by the new one, it is so simple.

    Browse anonymously anywhere you go with the Onion Pi Tor proxy. This is fun weekend project that uses a Raspberry Pi, a USB WiFi adapter and Ethernet cable to create a small, low-power and portable privacy Pi. First, plug the Ethernet cable into any Internet provider in your home, work, hotel or conference/event. Next, power up the Pi with the micro USB cable to your laptop or to the wall adapter. The Pi will boot up and create a new secure wireless access point called Onion Pi

    According to the Tor website:

    Journalists use Tor to communicate more safely with whistleblowers and dissidents. Non-governmental organizations (NGOs) use Tor to allow their workers to connect to their home website while they're in a foreign country, without notifying everybody nearby that they're working with that organization.
    Groups such as Indymedia recommend Tor for safeguarding their members' online privacy and security. Activist groups like the Electronic Frontier Foundation (EFF) recommend Tor as a mechanism for maintaining civil liberties online. Corporations use Tor as a safe way to conduct competitive analysis, and to protect sensitive procurement patterns from eavesdroppers. They also use it to replace traditional VPNs, which reveal the exact amount and timing of communication. Which locations have employees working late? Which locations have employees consulting job-hunting websites? Which research divisions are communicating with the company's patent lawyers?
    A branch of the U.S. Navy uses Tor for open source intelligence gathering, and one of its teams used Tor while deployed in the Middle East recently. Law enforcement uses Tor for visiting or surveilling web sites without leaving government IP addresses in their web logs, and for security during sting operations.

    Some notes about my experience using the Raspberry Pi model B…and you get it running Linux Debian on it!

    The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.

    […]

    We don’t think that the Raspberry Pi is a fix to all of the world’s computing issues; we do believe that we can be a catalyst. We want to see cheap, accessible, programmable computers everywhere; we actively encourage other companies to clone what we’re doing. We want to break the paradigm where without spending hundreds of pounds on a PC, families can’t use the internet. We want owning a truly personal computer to be normal for children. We think that 2012 is going to be a very exciting year. [About Raspberry PI]
