Introduction

Most software companies run in that dilemma. In order to write software that works, you want to write some tests. The question for many of these companies is: what kind of tests are most efficient for my business?

Here we talk about seven common test practices in the software industry.

1. Unit Testing

Probably the most used form of testing is Unit Testing. This is easy to write and very effective in discovering bugs. If you are looking at verifying correctness, this is 100% what you need to have to test your software.

Why is it easy to write?

In most cases, Unit ...

In the last few days, we started hearing about a massive bug in the implementation of the VM memory handling.

Intel has been frantically working on fixing host machines kernels in order to prevent one VM from accessing the memory of other VMs that run on the same machine.

Of course, most users are not going to attempt to read someone else memory so in that sense, most of us are relatively safe. But all of those who are not so lucky and have uninvited guests on their systems are running at very high risk. The information available from Intel says the memory is accessible only in Read mode. ...

We have been running Drupal for some time now and we have noticed that it generates a very large amount of warnings in our log files.

The warning is in link with improperly formatted strings. PostgreSQL tries to follow the SQL specification to the letter and that means you cannot use the backslash character to escape special character sequences (such as \n for a newline character.)

I knew that in most cases the error was generated because of the function saving a full page or some other content in the cache. In that case, the system includes the characters: \012 and \015 (\n and \r.) That ...

In June 2008, Made to Order Software created a new software library called odbcpp. This library is an Open Source C++ wrapper of the Open Database Connectivity (ODBC) library started by Microsoft in 1988.

ODBC hides the details of back-end database systems. In other words, if you support ODBC, you can effortlessly connect to a very large number of database systems such as MS-SQL, Access, Oracle, MySQL and PostgreSQL.

odbcpp is an extension for C++ programmers. It is easy to use and it is a great solution to avoid many bugs as it will automatically handle all the possible ODBC errors for ...

This year, 2008, I decided to register and go to LinuxWorld. It is in August and my kids are not at school so it was easy to manage. Also, I had to go to the French consulate to get a birth certificate for my daughter. In other words, I had the chance to do two things at once!

I found it quite interesting to hear that many people were not too excited about the event. Many of the people walking around are like me: they themselves sell their own Linux solution. In other words, they are not going to be customers. I had the chance to talk with Roger Levi, the Vice President of the Open Platform ...

Dear reader,

Yes. With all these terms, it is quite easy to get lost.

As a developer, my skills are quite extensive. I started with Logo, learned assembly language, BASIC, C, C++… and all these other languages in between, those that most people pass by such as Ada, Eiffel, Icon… And the languages you kind of have to learn because you’re in it: Bourne Shell, configuration files for 100 different software, Makefile, etc.

And once you know all of these languages, you think you’re done. Well… Not quite!

The web has got it’s own set of languages! It
