Setting Up a Git Server on Ubuntu

Git is a version control system used by many projects such as Linaro, the Linux kernel, Android, Eclipse, Qt and more. For projects that can not afford their own servers and still need to collaborate, hosted git is available from github and as today there are a total of 2,769,642 repositories (private and public) hosted on github. For software developed internally, you can start to setup you own Git server by following some simple steps (in Ubuntu). Installing the Git Server Update Ubuntu and install git-core: sudo apt-get update sudo apt-get install git-core That’s it. Installing Gitolite Gitolite allows you to setup git hosting on a central server, with fine-grained access control and many more powerful features. First get gitolite with git: git clone git://github.com/sitaramc/gitolite.git Obtain a public key based access to your server, so that you can log in from your workstation to the server without getting a password […]

Best Practices for Writing Safer C Code

Thomas Honold wrote an article published on EETimes giving 17 steps to safer C code. Not only this article provides tips to write safer C code, but I believe those steps are simply best practices when writing C code for embedded systems as they shorten the software life cycle by making it easier for a software team to write, debug and maintain code and by improving the software QA procedure. Here’s a summary of the 17 steps to achieve safer C code: Follow the rules you’ve read a hundred times: Initialize variables before use. Do not ignore compiler warnings. Check return values. Use enums as error types. Define an ENUM_MAX value at the end, so that the code to check the range does not have to be modified each time you add a new error code. Expect to fail Always assume there will be an error and set to default […]

What Programming Language Should I Learn ?

“What programming language should I learn ?” is a question often asked by people new to software development. The answer is always “it depends”. But for embedded systems, it seems C language is a must as you can see in the chart below (Source: “The 2011 Embedded Market Study” by Embedded.com). For the 2011 survey, 1886 respondents from across the embedded industry answered that their embedded project was mostly programmed in C language (62%), followed by C++ (22%), assembler (5%) and Java (2%). The other languages were all under 1%.
