How Much MB or GB Space Can Be Freed Up on your iPhone, iPad?

Last August, we reviewed the free Windows utility called PhoneClean, the uniquely designed application allows users to free disk space on there iPhone, iPod touch or iPad by cleaning up the files that are no longer useful to the system. The iMobie, creator of the program, has now informed us that PhoneClean has been thoroughly redesigned and upgraded to version 2, and its Mac version also available.

For Mac

The PhoneClean scans on your machine, looking for temporary files that are no longer used, but for some reason kept there. It does not erase progress of games or any application data, even if they are only remnants of unused files.

Installing and Configuring MiniDLNA Server On Raspberry Pi

We have already setupped the Raspberry Pi to download files from internet and share them wirelessly over network acting as an NAS. Now it's time to further enhance this functionality to share multimedia content (audio/video/images) using DLNA protocol so our Raspberry Pi can act as an self contained multimedia downloader and server.

Enabling DLNA allows compatible networked device like TV's, cellphones, music systems and computers to enable seamless sharing and playback of digital media between devices. DLNA uses Universal Plug and Play (UPnP) for media management, discovery and control. Follow the instructions ahead to install and configure popular Linux DLNA server utility MiniDLNA on Raspberry Pi running Raspbian.

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.

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.

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.
