While Raspberry Pi certainly is a cheap mini-computer, adding accessories to it blows up ownership costs a lot. While adding WiFi is relatively cheap, finding a compatible Bluetooth Low Energy 4.0 (BLE) for a bargain is hard. Luckily, I found the Orico BTA-403 Mini Bluetooth 4.0 Adapter Dongle which comes with CSR8510 Low Energy Chip and is compatible with Linux and Raspberry Pi despite being not listed as such in the description, this is certainly a must-have deal for $8 including worldwide shipping. Instructions for setup are as shared below.

There are lots of scanned PDF files need to be copied, transferred or exchanged often on the Internet. However, scanned PDF documents are made from images and the file sizes are very large. It is not easy to send emails with large PDF attachments.

PDF Compressor aims to solve a common problem of today's electronic documentation. The majority of currently existing PDF files contains nothing but scanned copies of corresponding paper documents. Since the content of such files is mostly images, scanned PDF documents can sometimes be quite large, to a point when sending them in emails or via Skype becomes almost impossible. PDF Compressor allows its users to quickly compress such oversized PDF documents, enabling easier handling and significantly reducing disk space they take up.

PDF Compressor is a freeware Windows utility that compresses scanned PDF files and reduces PDF file size fast and easily. This tool allows users to change the compressing value to get better compressed result and content quality. Also, the program supports batch mode and lets users compress hundreds of PDF documents at one time.

A few days ago my friend experienced "lost disk space" on his 8 GB pen-drive while using the Videocon D2H external-disk TV recording functionality. The DTH STB asked to format the device to enable recording, after which only 149MB was left visible/usable on Windows. While inspecting the disk from "Windows Disk Management" console, it was clear the space was still there but is of an unknown format, the recording feature on STB deliberately converted the disk to a custom file-system to prevent piracy of recorded material. We simply need to reclaim the space using special utilities as demonstrated ahead.

Since Youtube caters to a wide-variety of users groups all around the globe, it imposes several types of restrictions to filter out non-suitable content citing various criteria like users Geographical location and age. We have already shared tricks to bypass Youtube country specific geographic censorship and even how to watch videos deleted from Youtube (providing they are still on Youtube cache servers distributed across the globe).

Today we will show a trick on how to bypass the "Youtube Content Warning : This video may be inappropriate for some users." without signing-in or need to have a Youtube/Google account (which also avoids tracking and prevents similar type of videos being shown on Youtube front-page when signed-in).
