In-Home Displays for Smart Grid – Atmel – Mentor Embedded

I’ve just attended a webinar organized by Mentor Graphics entitled “In-Home Displays: Enabling Smart Grid into every home” with Atmel and Mentor Embedded. This webinar is now available on-demand at http://go.mentor.com/hAz8 This webinar is divided into 2 parts: Frederic Gaillard – Product Marketing Manager at ATMEL – gave an overview of Smart Grid and its different components and presented Atmel Solutions: MCU/MPU, wireless chips (Zigbee/Wi-Fi) and touch screen chipset. Gordon Cameron – Business Development Manager at Mentor Embedded – focused on the difficulties in developing a user interface for In-Home Displays within a short time frame and how Mentor Embedded UI design solution Inflexion could help greatly reduce the development schedule. There was no external files for this webinar, so I created 2 PDF with the most relevant slides for your reference: Atmel Smart Grid and In-Home Displays Mentor Embedded In-Home Displays UI Development Tools Frederic Gaillard shortly explained the Smart Grid Ecosystem and it’s different components as you can …

Sharing Thunderbird Emails between Windows and Linux

I’ve used Windows XP with Linux in a virtual machine (VirtualBox) for a while. But since this proved to be very slow,  I’ve just installed Ubuntu (dual boot mode) in my PC. However, I wanted to be able to use the same Thunderbird profile in both OS. So here’s how to do: After installating Ubuntu, open a terminal window and: 1. Install Thunderbird: sudo apt-get install thunderbird 2. Start Thunderbird in Profile Manager mode: thunderbird -profilemanager Then create a new profile (any name) and click on “Change folder” and point it to your Thunderbird profile in Windows (Something like: Documents and Settings\username\Application Data\Thunderbird\Profiles\abcdef.default). You may delete the default profile and start Thunderbird. You should then see all your emails and RSS feeds in Thunderbird and receive and send emails in Linux as you used to in Windows XP.

ARM Techcon 2010 Proceedings and Presentation Slides

A lot have been covered at ARM Techcon 2010. I’ve blogged a few articles about ARM Techcon 2010, but there is a lot more to discover. A full set of documents and presentation slides shown at Techcon 2010 are available at http://vault.eetimes.com/armconference/proceedings/ The documents are divided in 2 main parts: Day 1: Chip Design Conference Day 2-3: System & Software Design Conference which are then divided into sub-directories with really (hmm) good names such as ATC-100, ATC-101… to ATC-165 so that everybody can clearly see what the subjects are. You’ll also have the Keynote and Industry addresses. Since this blog is more related to “System & Software Design” I’ve been through the pain of downloading all documents of this section and checking the subjects. You may do it for “Chip Design Conference” if you wish, I’m sure you’ll enjoy it. You’ll have one or two documents in each folder. If you have two, most of the time there will be …

Digital Signage Standard: Open Pluggable Specification (OPS)

A while ago, we discussed about Popai Digital Signage Standards, mainly focused on software and client/server interoperability. Intel has just released a new standard for Digital Signage: Open Pluggable Specification (OPS). Here’s the description of the specification on Intel website. The Open Pluggable Specification (OPS) helps standardize the design and development of digital signage devices and pluggable media players. Intel created the OPS to address digital signage market fragmentation and simplify device installation, usage, maintenance and upgrades. The OPS enables digital signage manufacturers to deploy interchangeable systems faster and in higher volumes, while lowering costs for development and implementation. Installing digital signage equipment based on Intel® architecture helps you implement scalable digital signage applications that can network easily with other equipment. This simplifies interoperability and application upgrades designed to meet the digital signage requirements of individual customers, while helping to future-proof technology investments. You’ll need to fill a form to apply to have the “privilege” to access the specification. You’ll …

How to check open files for a process

While debugging your program, you may encounter the message “Too many open files”. One way to fix the issue could be to review your code and check open, fopen, socket and pipe calls are matched with close and fclose calls, but with large projects this may be cumbersome. A better way is to list the open files using the proc filesystem. I’ll use VirtualBox program as an example since this is running in our server. First, locate the process ID (PID): pgrep VirtualBox 3901 3950 Then list the file descriptor opened for process 3901 sudo ls -l /proc/3901/fd total 0 lrwx—— 1 root root 64 2010-10-05 14:52 0 -> /dev/pts/1 lrwx—— 1 root root 64 2010-10-05 14:52 1 -> /dev/pts/1 lr-x—— 1 root root 64 2010-10-05 14:52 10 -> pipe:[15825] l-wx—— 1 root root 64 2010-10-05 14:52 11 -> pipe:[15825] lr-x—— 1 root root 64 2010-10-05 14:52 12 -> pipe:[15829] l-wx—— 1 root root 64 2010-10-05 14:52 13 -> pipe:[15829] …
