Migrating a WordPress Blog from Apache2 to Nginx

This blog is hosted on a Linode VPS with 512 MB RAM and running Ubuntu 11.10. Up until today, Apache2 was the web server, and it worked fine except sometimes, it reached connection and memory limits, and the blog would go offline for a short period of time, especially right after a new blog post. So this week-end, I decided to switch to nginx (pronounced engine-x) web server which is said to use less memory than Apache2. Let me know if something suddenly stopped working… nginx is a relatively recent web server, and the documentation on the web seems to become outdated pretty fast, so I’ve decided to document what I’ve done. The first thing I would recommend is to try it in your own local server first,  and make sure most things are working including plugins. Testing your WordPress blog with nginx in a local server I run Ubuntu […]

Freescale Announces Availability of Kinetis L Series Cortex M0+ MCU and Freedom Devkit

ARM unveiled its ultra-low power Cortex-M0+ core back in March, and Freescale and NXP also announced their plans to use this new core in some of their micro-controllers destined to power the internet of things. Yesterday at Freescale Technology Forum (FTF), Freescale announced the availability of alpha samples of its Kinetis L series. This new low power MCU family will allow existing 8-bit and 16-bit architecture to be replaced by 32-bit architecture without increasing power consumption, cost or size, and the company expects them to be used in devices such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control. The ARM Cortex-M0+ processor is said to consume about a third of the energy of any 8- or 16-bit processor, while delivering between two to 40 times more performance. Kinetis L series MCU  can consume as low as 50 uA/MHz in very-low-power run (VLPR) […]

Getting Started with Emcraft Systems Cortex M3/M4 Starter Kits Running uCLinux

A few months ago, I wrote a post about running uCLinux on Cortex M3/M4. Since then I’ve had the opportunity to play a with Cortex M3  & M4 boards capable of running Linux, as last week, I received Emcraft Systems Freescale K70 Starter Kit together with their MicroSemi (previously known as Actel) Smartfusion SoM. Today, I’ll show some pictures of the baseboard and modules I received in the kit, and some details about the documentation and how to get started with the modules. Unboxing Pictures Here’s the baseboard with Ethernet, USB interface using USB-UART bridge connected to the UART0, JTAG connectors (P3 and P5), two push-buttons and a breadboard for easy access to unused signals (ADC, I2C, SPI, UART and GPIOs). P4 and P6 are the sockets to plug in the SoM. There is a lithium-ion battery (CR2016) at the back of the board for the RTC clock. As previously […]

WM8850-MID Android 4.0 Tablet Unboxing and Review

I recently bought an Android 4.0 tablet with a 7″ capacitive touchscreen based on the new WonderMedia WM8850 processor (Cortex A9 + Mali-400). In my first post, I called this tablet UGoos UG-LMW70, but I just received a no brand package with nothing mentioning Ugoos or the model number UG-LMW70 anywhere. Android settings just show WW8850-mid for the model number. The tablet comes with a 5V power supply, a miniUSB to USB cable, a short miniUSB to USB female adapter, headphones and a user manual in English explaining how to use Android, but nothing about the tablet itself. The tablet has vol-/+ buttons and a power button (left side below), and a power jack, microSD slot, headphones jack, a USB host port, a mini HDMI port, a miniUSB port and a microphone (right to left). They did not include a mini HDMI to HDMI cable, so I did not try HDMI […]

Hardware Packs for AllWinner A10 Devices and Easier Method to Create a Bootable Ubuntu 12.04 SD Card

Linaro has a tool called linaro-media-create to install Linaro Ubuntu to an SD card by passing the device, hardware pack file, the rootfs and the board as arguments. Hardware packs are files that contains hardware specific binaries and configs files (e.g. bootloader, kernel…). I’ve done something similar (albeit more basic) for AllWinner A10 devices so that you can easily install and run Ubuntu (and possibly other distributions) on an SD card. I’ve written 2 scripts for this: a10-hwpack-bld.sh – Script to generate evb.bin, build the latest u-boot and linux kernel, retrieve some config files and compress all this in an hardware pack file a1x-media-create.sh – Script to make a bootable SD card for AllWinner A10 devices. You can get the scripts with git:

I’ve only tested it with Mele A1000, but if you have other A10 devices such as MK802 mini PC or MINI X media player, it should […]

Raspberry Pi Debian Wheezy Alpha, Bodhi Linux Alpha and Pwn, A Security Test Suite

I still haven’t received my Raspberry Pi board, but there have been a couple of interesting Raspberry Pi software news this week. Raspberry Pi Debian Wheezy “Alpha” This is an update to Raspberry Pi Debian  Squeeze 6.0, based on Wheezy (Debian 7.0) and the maintainer (Alex) is looking for volunteer to help test it and iron it out, before the Raspberry Pi foundation officially announce the distribution on its blog. This distribution comes will the following: * Scratch, Python, Midori etc as before * A configuration tool for common initial setup tasks (resize root partition, change keyboard layout) * omxplayer * USB drives auto mount * Lots more This is alpha quality, so you can’t expect it something very stable, but if you want to test drive it, you can download it via BitTorrent (447 MB). Sha1sum: bdad7f1c504e22f8d754028843abb9da4330107f. You can login with the following credentials: User: pi | password:raspberry Known […]
