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 […]

Getting Started with Raxda Rock – How to Generate and Flash Ubuntu Saucy Server and Desktop Images

I’ve already written a guide showing how to build and install Android in Radxa Rock. Today I’m going to build the Linux kernel, generate a Ubuntu server images based latest Ubuntu Linaro server release, flash the image to the NAND flash, and show how to install LXDE or XFCE desktop environment. If you are just interested in installing one of the latest supported images, you can download Android, dual boot (Android/Ubuntu), Ubuntu ALIP, and Router images for Radxa Rock @ http://dl.radxa.com/rock/images/, and skip “build” and “generate” instructions, and just follow the flashing instructions below. All steps in this tutorial will be done in Ubuntu 13.10, and lots of the instructions below follow hwswbits blog and Ubuntu Radxa Wiki. Build the Linux kernel Let’s start by building the Linux kernel. I’m assuming you’ve already install development tools in Ubuntu (e.g. apt-get install build-essentials). You can refer to the list at the beginning […]
