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.

Is the Open Source costing us money?

More and more, enterprises make use of Open Source software. Why is this a good idea for your company as well?

Many people are scared to do the move. The result is very costly. When you use proprietary software, each time you need an upgrade, you need to pay for it. And in most cases, it is not just once, but a number of times equal to the number of computers you own or the number of staff that use the software. A $200 software may sound really cheap. But if you have 1000 staff, it makes it $200,000.

This is of course very good business for the vendors. However, many small companies just ...

Metrics. Why are they needed?

When managing your life, when managing your work, when managing your business, you need to accomplish a certain amount of work to get where you want to go.

In general, it is difficult to judge how much work will be necessary to do one thing or another until you actually do it. So you setup goals and draw up plans to reach them and then you try to do all the work you assigned yourself to reach these goals.

One reason an Internet Business has an advantage is because the computer can do a lot of the work for you. It can give you information on how many people come to your website every week, ...

Really… What is a goal?

I’m writing this blog after meeting with a few people with great experience at the NCAE networking group in Roseville.

I have been in business for quite some time now and I have read many things about goals. But what is a goal? How do you set a goal? How do you make sure that you reach your goals?

So, let’s start by setting a goal.

“I want a home worth $1.2 million dollars”

Ah! Is that really a goal?

The truth is that this is so blurry that it cannot be a realistic goal, at least not for most people. This does not mean you won’t be able to get the home of ...

Microsoft: Vista Worries Cause Businesses to Consider Macs and Linux

 

Eweek reports:

“A recent survey shows that 44 percent of businesses are considering Mac OS and Linux rather than switching to Vista.”

We are seeing the barbarians at the gate now, and the MS empire begins to show its first signs of crumbling. And it’s been a long time coming, I’m afraid. It goes to show you how ineffective the US anti-trust laws are, and how the free market is self-regulating.

It seems that Microsoft is very out of touch of what their customers really want, and is full steam ahead using its outdated business model of forced upgrading. Looks ...

Server Switch!

For the last few days, Doug and I have been working on switching from our old server to our new server. The new one is with JohnCompanies.com that offers VPS (Virtual Private Servers). It was a nice surprise, the computer we have access to has 8 processors running at 3Ghz (”proven” by the Linux Bogomips computation: 5985.31) And so far, I’ve seen about 0.8% of one processor being used. The rest is 100% idle most of the time!

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:

WordPress at Made to Order Software!

Welcome on Alexis’ Blog at Made to Order Software Corporation.

This is my first blog! I’m glad I got WordPress to work with the m2osw style sheet. It is quite different from the default blogging board setup! Also I needed to make it work for several people on the same website without duplicating the code each time.

I did make changes to the code in order to achieve this feat. First, I had to access a specific database for each person to have its own blog (this may be just me who did not know how to use all the available features of WordPress, though.)

The following function ...
