LinuxWorld Conference & Expo 2008

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 ...

July 2008, a new limit reached!

I heard of Voyager 2 and the fact that it was still functional: 30 years after it left Earth! Just that is amazing to me.

The craft went through the termination shock several times now (5 if I’m correct). This is far. Further away from the Sun than Pluto. And Pluto is on average around 39.5 AU from the Sun. It is even further than Eris and Eris lies at about 67 AU on average.

AJAX, CSS, HTML, XML, SOAP, LAMP… and now Web 2.0?

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

Pointers and proper exception handling...

Many C++ programmers have been C programmers first. Therefore, a lot of times, you find statements written this way:

ptr = new type;

if(ptr == 0) // handle error...

This is a C programmer that does not yet know that the new operator will throw an error if the allocation cannot happen. This makes a lot of sense, but what does that mean to the C++ programmer?

Order Made! v1.9 published

After adding the Menu Only option in version 1.8, we now fixed a couple of small bugs and published version 1.9 of Order Made!

At times, the toppings selection would wrap your entries in a rather ugly way. We added the necessary HTML code to avoid this problem. In some cases, your toppings sub-window will look a lot better.

PHP eFax available on our website!

 

I’m glad to announce that PHP eFax is now available for sale on our site. For only $95, you can send faxes within minutes.

It took me a whole week to program that object and a lot of testing. Yes, I sent a lot of faxes before to make it work properly.

If your company needs to send faxes via their website (or their customers website) it can easily save money here! By getting PHP eFax, you won’t need to program anything, really. All you need is to set the fax data in an object and call send(). In minutes you will be sending faxes. You can see a sample here:

The assert() macro in C/C++

 

This is a subject that comes back all the time in C/C++ boards.

Should you use assertions?

The answer is clearly yes. But the C/C++ assert() function is usually defined using a macro. Macros have several problems. The most common ones are: they offer no type checking, they do not warn you about weird side effects, they have a different syntax than the C/C++ language itself.

One good thing: for a fast program, the debug code used to check parameters, results, etc. is gone.

One really bad thing: if the expression in the macro has a side effect, the release program is different from ...

HTML Forms and the action attribute

Today I had to debug a set of HTML pages. One feature of a website would not work with Internet Explorer. The code was like this:

Cross-platform software development and engineering

Well, It certainly seems that Dell and HP are defining the trend of the future by offering their computers with Linux pre-installed. For software developers to catch up to this trend, .NET and other mono-platform development tools will not cut it! Retooling of code is inevitable so when you are faced with this crossroads do not spend the time and money on a band aid. Check out molib and sandbox and learn how your software development efforts can go cross platform once and for all! Save expensive development hours, improve the quality of your code, and make your code base more safe and secure. ...
