Digital Signage TCO Calculator

AMX has recently released a Total Cost of Ownership Calculator for digital signage comparing two different setups by taking into account the following parameters: Digital Signage Requirements: Number of Players Hours per Day Days per Week Weeks per Year Expected life in years US State Deployed (For electricity rates) Cost of Development for 2 products: Media Player Cost Per Unit Initial Software Cost Initial Subscription Fee Monthly Subscription Fee Energy Efficiency: Player Power Consumption in Watts Hardware Design: Type of storage: Solid State / Hard Disk Fan: With or Without The result of the calculation will show you the total cost in a graph, with the lifetime electricity cost, total subscription cost, total software cost and total player cost. If you purchased the players and plan to manage the devices by yourself, you won’t have to pay any subscription fees. However,  you’ll still have to consider the maintenance costs. In that case you may use the “Monthly Subscription Fee” field …

Embedded Systems Hardware & Software Trends for 2011

VDC Research – a US company specialized in technology market intelligence – recently released two reports about embedded systems trends for 2011. The first report focuses on hardware and the second on software. The first report entitled “Top 10 trends for the embedded hardware and systems market in 2011” listed the following trends: COMs gain traction as time-to-market accelerators for OEMs By combining COM express modules with off-the-shelf COMs, suppliers are able to offer several different configurations of CPU boards and leverage COMs’ interchangeable characteristics. CPU vendors can thus offer a fairly wide range of boards without incurring high design and inventory carrying costs. PC/104 module family under pressure Although VDC data projects the PC/104 family will experience a single-digit rebound from the low points of the recent recession, vendors will have to commit resources to develop newer strategies in order for this technology to remain viable. Otherwise, the recovery of these architectures is likely to stall or decline in …

Software Code Review Study and Best Practices

Many companies perform software development without code reviews – the systematic examination of source code intended to find and fix mistakes overlooked by the original developer – or at least without formal reviews. I’ve recently come across The Value and Importance of Code Review white paper from Klocwork who commissioned an independent company to survey IT professional. This paper shows code review practices have not changed much over the years even though software development have dramatically evolved. Here are the key findings of the study: Code reviews are valuable, but approaches tend not to be formal. Modern development is increasingly complex,  and code reviews are not keeping pace. (i.e. Code reviews are low priority tasks) Code reviews don’t always include the right people. (e.g. Architecture and QA Team are left out, only only software engineer are part of the review) Tools don’t play a significant role in reviews. (e.g. code coverage and code analysis tools) Process and time limits inhibit …

Detecting Code Duplicates in C/C++ with CCFinderX

Over time, as your source code repository and software team(s) grow, you may have more and more code that just does the same thing. This is obviously not desirable since several persons work on code doing the same thing, so you just pay twice for the cost for development and debugging. To avoid this issue, proper team communication and management must be in place (e.g. discourage copy/paste of source code, use a common source control repository..). However, it might be difficult to always detect where the code duplicates are. Luckily, code duplication analysis tools such as CCFinderX are here to help. As described on CCFinderX website: CCFinderX is a code-clone detector, which detects code clones (duplicated code fragments) from source files written in Java, C/C++, COBOL, VB, C#. CCFinderX is a major version up of CCFinder, and it has been totally re-designed and re-implemented from scratch. Its new design and technologies aim at improving performance, enabling a user-side customization of …

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. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and …

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 …
