Sure, but competition is good for the user.

Defect-free software does not exist.

I was going to visit IBM for six months as a visiting scientist. Now, six months is a lot of time, so I came with a whole list of projects that I might want to work on.

I don't expect an overnight change of all desktops to what the US Military used to call B3 level security. And even that would not stop users from shooting themselves into the foot.

However, writing software without defects is not sufficient. In my experience, it is at least as difficult to write software that is safe - that is, software that behaves reasonably under adverse conditions.

I want to avoid locking people into solutions that work only with Postfix. People should have a choice in what software they want to use with Postfix, be it anti-virus or otherwise.

Qmail out of the box works fine, so people will want to use it regardless of licensing restrictions, even when the software does not ship with their system software.

When I write software, I know that it will fail, either due to my own mistake, or due to some other cause.

The challenge with Postfix, or with any piece of software, is to update software without introducing problems.

Sure, but competition is good for the user.

As of today, the Postfix mail transport agent has almost 50,000 lines of code, comments not included.

Like all software, Qmail can survive only when it keeps up with changing requirements.

Most of the effort in the software business goes into the maintenance of code that already exists.

Coming back to the topic of computer security, the TCP Wrapper is an example of such a safety net. I wrote it when my systems were under attack by someone who appeared to walk through walls.

This will surprise some of your readers, but my primary interest is not with computer security. I am primarily interested in writing software that works as intended.

For many people my software is something that you install and forget. I like to keep it that way.

At the time the Sendmail program had a very poor reputation with respect to security, with four root vulnerabilities per year for two successive years.

One bug in an SMTP server can open up the whole machine for intrusion.

Windows favors multi-threading, which means that a service is implemented by one single process.

Writing software that's safe even in the presence of bugs makes the challenge even more interesting.

Postfix keeps running even if one Postfix process dies; Windows requires that someone restarts the service.

Lack of documentation is becoming a problem for acceptance.

The Postfix security model is based on keeping software simple and stupid.

In a previous life I wrote the software that controlled my physics experiments. That software had to deal with all kinds of possible failures in equipment. That is probably where I learned to rely on multiple safety nets inside and around my systems.

My reply is: the software has no known bugs, therefore it has not been updated.

Adding functionality is not just a matter of adding code.

Some people don't like competition because it makes them work harder, better.

Anytime you have a difficult encounter with your child, there is a good chance that at least one of these factors is bringing out the worst in him or her: transitions, time pressure, competition for your attention, conflicting objectives.

I want to be the first lady to land a quadruple jump in competition. As I grow older, I know that my skating style will develop and mature.

The time has come for the American government to recognize the damage that has occurred to our economy, and to take firm action to curtail what I believe is both unfair and illegal foreign competition.

In my fifty years of experience and memory, I have seen the most amazing increase in the standard of living of a people ever achieved anywhere in the world. This is why I am so sure that our system of free competition and industrial development is sound and must be preserved.

We got to know the competition very well. In the '50s popcorn made a big growth in sales. Our main push was to produce the best quality and sell in quality retail outlets.

We live in a time today where we face fierce global competition.

The person who figures out how to harness the collective genius of his or her organization is going to blow the competition away.

And while the law of competition may be sometimes hard for the individual, it is best for the race, because it ensures the survival of the fittest in every department.

The time is coming when the pressure of population on the means of subsistence will be felt here as it is now felt in Europe and Asia. Then will the world enter upon a new stage of its history - the final competition of races, for which the Anglo-Saxon is being schooled.

Running became boring because it's so predictable. I got to a point where I knew what my competition could do.

There are horses people use for competition, and if they don't perform well or go lame, then people ask the vet to put them down to get the insurance money. And my vet knows I love horses, so he gives them to me.

Well, we know that people in Australia love the idea of both Impulse and Virgin Blue getting up and adding a bit of competition, and it's fun to be able to deliver it.

I kinda see everyone as competition. I'm a very competitive person. But I think that's good. Competition is great. And as long as it's friendly and not a malicious thing, then I think it's cool.

The stark reality facing us today is that without the labour reforms, workers will get neither the income nor jobs in the face of cut-throat global economic competition.

I ride my horse at competition level.

I don't see myself as competing with other actresses. I mean, I went through a time when I was in New York, and I was going to lots of auditions and trying to get parts, but even then, you're not really competing with the other actresses. There is a competition going on, but it's not like something you can win in that way.

Common sense tells us that this explosion of media sources should eliminate any concern over a lack of diversity of views in the marketplace and competition.

No, there's not much competition between puppeteers in general because everybody's working their own style.

I think it's good to have competition. Now we have a third country that can launch astronauts, so it's good for all of us. It makes us a little bit more competitive and wanting to be the leader.

My commitment to Atlanta and passion for sports and competition make this acquisition a perfect fit for me.

And what it depends on, of course, is whether the story itself is worth the ethical compromise it requires and whether the competition is onto the story.

Good will is the one and only asset that competition cannot undersell or destroy.
