How-to Autostart a PC Automatically When Connecting it to the Mains Power

I’ve decided it would be good if I could just hide the computer under the table, as I never use the DVD writer, and I can access USB ports for removable storage or debug board via a USB hub on my table. The only problem is that I would have to go under the table to press the power button each time I want to power on the computer. Feasible, but not very convenient. Every morning, I connect a power strip to the mains supply for my computer, monitor, and related equipment, so it would be good if the computer could just start when I connect it. I found out there’s an option in the BIOS of my main board to do just that. Most other people seem to use that feature to be able to automatically restart their computer after a power failure so that they can access it […]

Undistract-me Sends An Alert For Time-Consuming Commands in Linux

In Linux, some commands executed in the terminal such as make, wget, dd may take a while, so usually you’d just let them run in the background, and do some other work, drink tea, go for nap… while they are running, and come to check from time to time if the command has completed. Sometimes I even forget I run a particular command, and realize it has completed a few hours ago… It’s possible to add some command at the end of your command line, but it can be cumbersome, and you may forget to do it. The best would be automatic alerts for commands that take a long time, and undistract-me just takes care of that by sending an alert for commands that take more than 10 seconds (by default). In Ubuntu 12.04 and 12.10, you can install undistract-me as follows:

sudo add-apt-repository ppa:undistract-me-packagers/daily
sudo apt-get update
sudo apt-get install undistract-me

sudo add-apt-repository ppa:undistract-me-packagers/daily

sudo apt-get update

sudo apt-get install undistract-me

Undistract-me is part of Ubuntu 13.04 or […]

How to Autostart XBMC in Android

Android is great thanks to its versatility and the ability to install the apps you need. However, if you have an Android set-top box or mini PC connected to your TV, you may just want to use it as a media player running XBMC, and clicking on the XBMC icon each time you start your device is not ideal. Luckily, there’s an easy solution to autostart XBMC or any application in Android: Install AutoStart – No root in your Android device. Run the application and select XBMC as shown below. There’s no need to tick “Show notification at boot-up”, since XBMC will just show in the foreground. Done! Next time you restart your device XBMC will run automatically. I’ve tried it in Tronsmart Prometheus, and it boots to XBMC within 50 seconds. If you want to use another app in Android, simply exit XBMC.

Droid Stick A2 mini PC Recovery with AMLogic’s Hardware Flash Tool

In some circumstances, for example by installing the wrong firmware or doing something wrong by playing god (as a root user), it’s possible to brick your device. This happened to me with one of my Droid Stick A2 mini PCs based on AMLogic AML8726-MX. I changed some files in /system/etc/permissions directory, lost Wi-Fi access, and even replacing my changes with the backup files would not solve the problem. It also changed some permissions in the system, and it was not possible to restore the firmware the usual way. At the end of last month, dbtablets left a comment with download links to “Amlogic USB Burning tool”, but I only decided to give it a try today, and after some efforts I was successful. Just make sure you only use this method as last resort, i.e. a standard firmware upgrade does not work, and you’re about to throw your device in […]

How to Root Rockchip RK3188 mini PCs

CloudnetGo CR9 was the first Rockchip RK3188 mini PC I had ever seen reported, but since then others apparently based on the same board have started to show up including Tronsmart T428, Rikomagic MK802 IV, as well as Ugoos UG802B, UG007B and MK809 III. We’ll get a lot of choices, but most of time the firmware does not provide root access. I noticed AndroidPC.es published instructions to root those device in Spanish yesterday, but today, Geekbuying rooted the Ugoos devices with the same method used for RK3188 Tablets. You have to follow those 5 simple steps: Make sure USB Debugging is enabled on your mini PC (Settings -> Developer Options) Connect your RK3188 mini PC to a Windows PC via the USB port. Your PC should detect a new device, and try to install the driver. You can download the driver at https://www.dropbox.com/s/uqisjj4hqftlaxa/GEEKBUYING_Rockchip_Batch_Tool_v1.6.rar (password: GEEKBUYING.COM) After having installed the driver, download […]

How to Run Android Apps in Linux with AndroVM

You may want to run some Android applications in your computer. If you’re using Windows, there’s already a decent option with Bluestacks. If you’re using Linux, you could always install the Android SDK and run the emulator, but I don’t really like this option because of the user interface, and for people who don’t need to use the SDK it’s not really the simplest thing to install. The way to run Android apps in Linux is probably to run an x86 Android virtual machine in VirtualBox. Yesterday, I tried the latest development version of Android x86 4.2, but for some reasons I could not control the mouse, and had to perform all tasks with the keyboard. What I’m going to use today instead is AndroVM, an Android VM for x86 processor, that is even more easy to use than the Android x86 image. The instructions has been performed in a […]

Wandboard Dual Unboxing and Quick Start Guide

I’ve just received Wanboard Dual development board together with an enclosure, and Wi-Fi antenna. This board is powered by Freescale i.MX6 Duallite Cortex A9 processor, and comes with 1GB RAM, HDMI output and Ethernet. There’s also a version based on Freescale i.MX6 Solo with 512 MB RAM. You can refer to my earlier post for more detailed specifications. I’ll start by showing some unboxing pictures of the board, and write a quick start guide (casing assembly, Ubuntu & Android boot, and development). I also planned to run some benchmarks and test videos, as according to a poll on Wandboard website many people want to use it as a media player, but I’ll do that a bit later since the current Android image is not up to the task yet. Wandboard Dual Unboxing The package I received contained 3 boxes: one for Wandboard Dual board, one for the enclosure, and one for […]
