Installing Android SDK on Ubuntu 12.04

The official instructions to install Android SDK do not appear to be really up-to-date for Ubuntu 12.04, so I’ll post how I’ve installed the Android SDK and Eclipse on Ubuntu 12.04. First download and decompress Android SDK for Linux:

on 64-bit Ubuntu:

Sun Java is not part of Ubuntu packages anymore, so you’ll need to use openjdk instead

Now install the SDK

Android SDK Manager should show up. Use the default recommended packages and platforms, as well as any extra packages you may need, and click on Install x packages, accept all licenses and after installation is complete, the Android SDK is installed. Eclipse IDE is optional, but it’s the most widely used IDE to develop Android apps. You can install Eclipse as follows:

Once both Android packages and platforms, and eclipse are installed, start eclipse:

Then in the top menu, click on Help->Install […]

WiFi Tank Based on EEE PC, Arduino, Ubuntu and Node.js

Eight computer and electrical engineers built a WiFi Tank (Node.js robot) as part of a senior design project at Northeastern University, in Boston, Massachusetts. The robot brain is an EEE PC running Ubuntu, together with an Arduino board and is programmed using node.js. Each tank is equipped with a camera and 2 customized Wi-Fi repeaters (which it can drop it extend range), and it’s targeted at military operations or disaster-affected areas where network infrastructure is not available. Here are the key characteristics of this robot Robot controlled over WiFi 102 cm long, 71 cm wide, 41 cm tall, about 68 kg. Custom-built (except for treads) out of aluminum Range: 1 km with one on-board router and two droppable long-range repeater modules Running time: ~12 hours On-board webcam with microphone, night vision, pan and tilt On-board GPS for location tracking Custom-made remote user interface, works on any device with a web […]

Boston Ships Viridis ARM Server Based on Calxeda EnergyCore Cortex A9 SoC

At the end of 2011, Boston, a British IT company, announced plans for an ARM server based on Calxeda Quad Core Cortex A9 Server-on-Chip, and now the company recently announced they started to ship the server (called Viridis) to their first customers. We now have further details about the server including the key features: Ten times the performance at the same power in the same space Cut energy and space by 90% Easily scalable to thousands of nodes 48 SoC devices delivered across 12 Calxeda EnergyCard modules Each EnergyCore SoC contains an ARM quadcore processing unit, providing a total of 192 cores per 2U enclosure Low power consumption: <300W with each SoC consuming between 0.5 to 5W depending on the load. Up to 24 SATA HDDs or SSD devices Up to 192GB of RAM per 2U enclosure A Calxeda EnergyCard (pictured below) features 4 Calxeda EnergyCore ECX-1000 SoC which can […]

Quick Binary Debugging in Linux with Strace System Call Tracer

I’ve recently come across strace, a debugging utility for Linux that “monitor the system calls used by a program and all the signals”. It may not be that useful if you have the source code and can run other debugging tools such as gdb, or simply add printf to your code. But if you don’t have source code of the program, or you are a system administrator who wants to check if the program fails due to file access reasons, for example, this is really a great tool as it may help you find out which file causes problem. In my case, I was trying OpenGL ES on an ARM platform, and at least part of the code comes in libraries that are only available in binary form. I got the following error message running es2_info (part of mesa-utils-extra): UMP: ump_arch_open() failed to open UMP device driver ********************************************************************* ERROR: In […]

Amahi 6.1 for Ubuntu 12.04 Released

Amahi has just announced the release of Amahi 6.1, Ubuntu Edition, an Home Digital Assistant (HDA). Amahi used to only work for Fedora and this is their very first stable release for Ubuntu 12.04. The key features of Amahi 6.1, Ubuntu Edition include: Greyhole 0.9 (storage pooling technology) Reliability fixes and updates New look Support for 32 / 64-bit Desktop and Server versions of Ubuntu Improved cloud storage with Amahi Sync Preliminary support ARM platforms such as PandaBoard and BeagleBoard One-Click App installs via Amahi’s application store If you want to get started with Amahi, you’ll have to register (and get an install code), and follow a few command line instructions. The instructions are the same to install on ARM platforms (assuming you already have Ubuntu 12.04 running), but Amahi developers recommend to install it to an hard drive instead of an SD card for performance reasons. They are also […]

webOS Community Edition Release for HP TouchPad

Open webOS 1.0 is planned to be released in September 2012, but in the meantime, the development team has released an intermediate webOS “Community Edition” for the HP TouchPad. This code is different from the Open webOS project, and is composed of additional components from the current release of webOS for the TouchPad. The open webOS project team has been working with WebOS Internals to bring this release out for legacy TouchPad devices. Thanks to the release of the webOS Community Edition, it is now possible to learn how the TouchPad works, modify your TouchPad experience and then apply that to Open webOS 1.0 once it is released. The Community Edition only supports HP TouchPad, whereas Open webOS 1.0 release will enable the community to port webOS to different hardware platform, and add more features by using open source stacks such as BlueZ bluetooth and GStreamer. You’ll need to download […]
