Flappy Bird Sucks, Let’s Play Flappy Tux Instead! Or How to Modify APK Files

Flappy Bird is a ridiculous fad, and I promised myself not to write about this silly game. I managed to resist when somebody showed off their Arduino powered real-life Flappy Bird, but then XDA developers mentioned one of their member posted instructions to customize Flappy Bird game. I thought it might be fun to personalize the game with pictures of friends or family members, and at the same time, learn how to hack apk files. Instead of real persons, I’ve replaced the original bird, by Tux, the official Linux mascot, flapping wings not included. The instructions in XDA dev forums are mainly for Windows, but I’ve adapted them to Linux, and “created” “Flappy Tux” from Ubuntu 13.10. I’ll assume you’ve already installed OpenJDK and the Android SDK and have a working Android app development environment. I think we just need adb and aapt from android-sdk-linux/platform-tools/bin to be in the path. […]

Try Ubuntu Touch on Your Computer with Ubuntu Touch Emulator

Canonical has just announced Meizu (China) and Bq (Europe) will be the first manufacturers to launch Ubuntu Touch phones at the end of 2014. But if you want to try Ubuntu Touch, and don’t own a Google Nexus 4 or 7, or simply don’t want to flash Ubuntu Touch to your devices, you can do so using Ubuntu Touch x86 Emulator in your computer running Ubuntu , or in an Ubuntu Virtual machine in Virtualbox or VMWare. The emulator has been available since last November, but Ricardo Salveti announced an updated version, the first public preview, with the following changes: Better TLS handling (not using the Android slots, but using pthread_set/getspecifics instead) Qt packages compatible with OpenGL ES 2.0 available at https://launchpad.net/~rsalveti/+archive/qt-gles-test It has been tried on Ubuntu Trusty (14.04), but I could run it just fine on Ubuntu Saucy (13.10), by following the instructions below in a terminal: Download […]

AllWinner Linux-sunxi Community Presentation and Status Report – FOSDEM 2014

Oliver Schinagl, a member of linux-sunxi community working on open source kernel and bootloader for AllWinner SoCs, has given a presentation of the community at FOSDEM 2014 to give an overview, and show what progress has been made to date. I’ll write a summary in this post, but if you want to watch the video and/or access the slides scroll down at the bottom of the post. After explaining what sunxi is, and introducing himself, he gave some information about AllWinner and their SoCs: Founded in 2007 in Zhuhai, Chiang now with 550 employees including 450+ engineers 15% market share in 2013 for tablet SoCs, only behind Apple. Products: F-series SoC (2010), A10 (2011), A13, A10s (2012), and A20 (2013). (cnsoft He skipped A31(s) and A80 here as they are not really supported by the community). They list “Open Source Source” and “GPLv3” in their marketing materials although they clearly […]

Intel Bay Trail Z3700 Series Overview, Benchmarks, Hardware, Documentation and Linux Support

After seeing the discussion about ARM vs x86 (Bay trail) for the future Dragon Pyra open source game console, I’ve realized many people, including myself, do not know about the different resources available to develop hardware and software for Intel Bay Trail SoCs for tablets such as Atom Z3740 and Z3770, so I decided to have a look. Intel Atom Bay Trail Z3700 Series Overview Intel Z3600 series and Z3700 series are respectively dual core and quad core Bay Trail-T SoCs for Android and Windows 8 tablets. There are 4 quad core models: Z3740, Z3740D, Z3770, and Z3770D, and 2 dual core processors: Z3680 and Z3680D. The dual core versions are reserved for Android only, and there’s no product page on Intel for now, so I’ll focus this post on Z3700 series only. I have no idea what the “D” in Z3740D is for, except it;’s not related to Desktop, […]

Keepod Unite Aims to Bring Computer Access to Africa with $7 USB Sticks and Refurbished Laptops (Crowdfunding)

The Raspberry Pi foundation has done a great job to bring to market $25 and $35 computers for kids to learn programming, but they have many other uses including hardware “hacking” and bringing low cost computers to developing countries. Keepod and NGO LiveInSlums have thought of an apparently more cost effective way to bring computing access to people living in slums in Nairobi, Kenya, by providing USB sticks (about $7) to boot refurbished laptops. This is absolutely NOT a $7 PC as a few other websites have mentioned. The goal is to facilitate NGO communication, the spread of knowledge and economic development in a way that’s personal and secure. The USB flash drives will belong to one person, and contains a Linux based operating systems with all files saved in the stick, and no modifications on the host computer which does not even need an hard drive to work, and […]

How to Upload YouTube Videos with the Command Line in Linux

Like many people, I access Internet via an ADSL connection at home. ADSL stands for “Asymmetric Digital Subscriber Line”, with Asymmetric being the key word here, as it just mean your download speed will be (much) higher than your upload speed. My ISP promises a theoretical 10 Mbps download speed, and 512 Kbps upload speed, and this is pretty close in reality: Data Rate: 10240 (downstream), 509 (upstream) kbps. Assuming a 265MB video, in the very best case (63 KB/s), it would take 1 hour and 12 minutes to upload a video to YouTube, but in practice it’s often closer to 2 or 3 hours. If it’s a video you’ve shot yourself, and copied inside your computer, there’s very little you can do, except processing the video with tools such as HandBrake to make it smaller before upload. But if the video files are located somewhere in the Internet, and […]

Building eLinks Text-based Web Browser with (Some Sort of) JavaScript Support

Yesterday, I’ve spend some time trying to find a text-based web browser with support for JavaScript. Although I doubt many people would need that, I’ll post my findings, and show how to build and enable Javascript in eLinks web browser to access the web from a terminal in Linux (Ubuntu/Debian). Bear in mind that the implementation is far from complete, and most pages won’t work, at least for now. Initial research pointed me to three potential candidates: links2, w3m + w3m-js extension, and elinks. Links2 used to have JavaScript, but support was poor, so they decided to remove it. w3m-js is an experimental patch to add JavaScript to w3m, but the link is broken, so we are left with elinks. If you just want a text based web-browser, and do not care about JavaScript, you can just install links2, w3m, or elinks with apt-get. The versions I’ve tried in Ubuntu […]
