aria2 - The Best Lightweight, Multi-protocol, Multi-source Download Accelerator For Linux

In search for the most stable yet low resource consuming download accelerator for my Raspberry Pi NAS, we have tested and written about excellent utilities like Transmission Bittorrent Client, pyLoad and FatRat which gets the job done. However, after extensive testing with all these I can now easily conclude that the best download manager for Raspberry Pi (or any other low-resourced Linux computer) is - aria2.

aria2 is an versatile multi-platform, multi-protocol download accelerator with lots of powerful features not available in any of the competing applications like the ability to download the same file from multiple URLS and protocols. Aria2 is available for Linux, Windows and Mac and supports multi-protocol, multi-segmented parallel accelerated downloads from HTTP,HTTPS,FTP,BitTorrent and Metalink protocols with download resume capability. Despite being a lightweight command line utility, you won't feel the lack of an GUI as it supports an XML-RPC interface for remote-control - there are quite a few handy GUI's available like web-interfaces, desktop clients and native mobile applications.

Autostarting Applications and Scripts After Launch Of LXDE GUI

We can launch applications and scripts as services during boot at various Linux run-levels as demonstrated earlier, however at-times we need to launch applications or perform scripted tasks only after the Graphical interface is loaded. For example in my usage scenario with Debian running on a Raspberry Pi, few services were failing to work as expected when launched using inti.d method as they require the host to be properly connected to the internet which only happened (in my usage scenario) after the GUI started loading.

Here is another handy way to auto-launch applications and scripts in a similar manner to "autostart" in Windows, we will be using LXDE "/home/pi/.config/autostart" folder to create shortcuts which will launch our executable after GUI starts loading.

Amazing Technology Will Popup Physical Buttons On Your Flat Touch Screen Tablet When Needed...

Miss the physical buttons when using cellphones and tablets, well you soon wont. Tactus Technology has developed a new tactile user interface for touchscreen devices that does exactly that. Tactus provides a new dimension to touchscreens by enabling real, physical buttons that rise up from the surface on demand, and then recede back into the screen, leaving a perfectly flat, transparent surface when gone. Watch out the CES2013 demonstration video posted ahead.

Launching Scripts and Applications on Raspberry Pi Boot

Users world-over are tweaking there way into Raspberry Pi making multitudes of things, like low energy consuming dedicated downloader, media center, Network Attached File-server (NAS), weather station, home-automation and robotics. To do all this tinkering, you will frequently need to make sure applications are launched when the Raspberry Pi is restarted.

Follow this simple tutorial to create services which will automatically launch at Debian boot. We will be using the Linux standard init.d method to launch our applications as services during various run-levels.

Xi3 - The New Breed Of Powerful, Tinker Friendly and Portable Modular Computers

We have seen success and demand for Mini computers like Cotton Candy, Raspberry Pi, Intel Next Unit Of Computing (NUC), O-DROID X and VIA APC 8750. But here is something which takes the prize for being the only viable looking portable solution to today's high-power desktop computing needs.

Xi3 modular computers are not only small but very rugged, the outer aluminum chassis not only acts as a good heat dispenser but also as an sturdy protector. The modular motherboard lets user buy an future-proof PC as they can simply swap out components easily as new technology gets available saving cost later on PC upgrades. Xi3 systems are also energy efficient and have models using just 40W of power.

Installing and using the Watchdog Timer on Raspberry Pi

watchdogIn it's simplest definition watchdog is a hardware and/or software timer-register which can used to trigger an system reset or action if something doesn’t works as expected. The watchdog timer performs regular heartbeat checks and if failed performs the pre-defined corrective tasks.

The now hugely popular mini-computer Raspberry Pi features the BCM2835 SoC which has an built-in hardware watchdog timer, this can be used to check tasks like network connectivity, system load, system freeze and other metrics like temperature to perform corrective measures like automatic system reset. Just follow the steps as instructed next to get started with using watchdog timer.
