Database Development

To me, legacy code is simply code without tests.

Encapsulation is important, but the reason why it is important is more important. Encapsulation helps us reason about our code.

Remember, code is your house, and you have to live in it.

How do I test private methods?" Many people spend a lot of time trying to figure out how to get around this problem, but, as I mentioned in an earlier chapter, the real answer is that if you have the urge to test a private method, the method shouldn't be private; if making the method public bothers you, chances are, it is because it is part of a separate responsibility. It should be on another class.

The most subtle bugs that we can inject are bugs related to inheritance.

Seriously, it is easy to believe that sealed and final are a wrong-headed mistake, that they should never have been added to programming languages. But the real fault lies with us. When we depend directly on libraries that are out of our control, we are just asking for trouble.

Programming is a lot like construction. Imagine a contractor building a house for you without a blueprint. Yikes! You might end up with a house that has 12 bathrooms, no windows, and a front door on the second floor. Plus, it probably would cost you 10 times the estimated price. Programming is the same way. Without a plan, you'll likely struggle through the process and waste time. You might even end up with a program that doesn't quite work.

When you start a session in R, the variables you create are in the global environment .GlobalEnv

What About Object Pooling? In early versions of Java (around the 1.2 time frame), the idea that long-lived objects were good gained currency. I specifically remember being told that "creating an object is the second most expensive thing you can do in Java" (the first being creation of a new thread). The answer, supposedly, was to avoid creating objects whenever possible. Instead, you were supposed to keep objects around and reuse them.

Jane had a mental block the size of the polar ice cap when it came to Andy's job. He said IT programming was no harder than learning a language but she'd never been able to do that either. As long as their computer at home let her occasionally shop on eBay she was fine not knowing why.

It's our patented Three Laws of Robotics. They're a fundamental part of every robot we manufacture, and we do not continue building or programming until it has become an integral part of them.

A person who cannot override genetic instructions when necessary is always vulnerable. Instead of deciding how to act in terms of personal goals, he has to surrender to the things that his body has been programmed (or misprogrammed) to do.

Breaking out of the fatalistic acceptance of genetic or historical programming requires, at the very least, a belief in freedom and self-determination.

They learned that small programs, like small cars, handled better, were more adaptable, and were easier to maintain than large programs.

Perl was designed as a programming language for automating system administration.

it's important not to divorce developers from the consequences of their work since the fires are frequently set by their code. So

The best thing is that everything that you make in Scratch can be stored directly on your computer or you can upload it on the Scratch website if you want to get feedback from other users.

You have experience in C programming? That's mainly what we need on that project.

There's a tradition among programmers to see mistakes not as a sign of failure but as "bugs" that can be fixed. An important part of becoming a programmer is to learn strategies for debugging—that is, how to identify and isolate a problem, then make changes to get around the problem.

hello world

The programmer lives in an imaginary world or virtual reality, chained away from the realities of the outside world.

Writing the first 90 percent of a computer program takes 90 percent of the time. The remaining ten percent also takes 90 percent of the time and the final touches also take 90 percent of the time.
