119: Data Types: DateTimes Part 2.

Dates and times are a lot more complicated than we normally realize. Having a specific data type to manage all the details is crucial.

118: Data Types: DateTimes Part 1.

Dates and times are a lot more complicated than we normally realize. Having a specific data type to manage all the details is crucial.

117: Data Types: Decimals.

If you need floating point values but find the accuracy of floats and even doubles to cause problems, then consider using the decimal type.

116: Data Types: Strings Part 3.

You need more than a bunch of numbers and logic to write an application. You need text and working with individual characters is not enough either.

115: Data Types: Strings Part 2.

You need more than a bunch of numbers and logic to write an application. You need text and working with individual characters is not enough either.

QA Friday 2016-May-27

Is there any point in learning how to code when I can just use the source code from another app?

114: Data Types: Strings Part 1.

You need more than a bunch of numbers and logic to write an application. You need text and working with individual characters is not enough either.

May 26, 2016•17 min

113: Data Types: Arrays.

You will often need multiple variables of the same type and while you can sometimes just create separate variables with their own names, what if you do not know ahead of time how many will be needed?

May 25, 2016•13 min

112: Data Types: Floats.

If you want to work with fractional values instead of just whole numbers, then floating point types are usually a good choice. They are different enough from ints that you need to understand how to use them.

May 24, 2016•10 min

111: Data Types: Enums.

What would you rather see? 1, 2, 3, or red, green, blue? Enums allow you to give meaningful names to values. Seems simple, right? It is, except for a few things you should be aware of.

QA Friday 2016-May-20

I met a person recently who has a college degree in computer science. He works at a local pizza shop. The question this week is not really a question but my thoughts on the situation. What went wrong? Or did anything go wrong?

May 20, 2016•8 min

110: Data Types: Void And Bool.

Void and bool are simple types that you can use with very little explanation. There are a few details that you should be aware of though.

May 19, 2016•12 min

109: Data Types: Ints Part 2.

You will probably have one or more ints in almost every method and class you write. They are everywhere so you really should know how to use them.

May 18, 2016•17 min

108: Data Types: Ints Part 1.

You will probably have one or more ints in almost every method and class you write. They are everywhere so you really should know how to use them.

107: Data Types: Chars And Bytes.

Chars and bytes form some of the most basic data types available. But what are they really? And what can you do with them?

May 16, 2016•11 min

QA Friday 2016-May-13

How do I use my foundational skills in programming to start making useful software?

May 13, 2016•6 min

104: Multithreading. Singleton Mistakes.

There is a big problem with Singletons especially in the C++ language. It is not obvious how to get them to work with multiple threads. You want one instance in your entire application and how do you handle the race condition when multiple threads ask for the instance at the same time?

May 10, 2016•12 min

103: Multithreading. Volatile.

Volatile is a keyword that allows you to turn off certain optimizations. Unfortunately, it is also used incorrectly many times as a way to synchronize threads.

May 09, 2016•10 min

102: Multithreading. Up And Down.

What if you just want to limit how many things you can have or can be done? This episode will explain another side of the semaphore sometimes called a counting semaphore.

May 05, 2016•9 min

101: Multithreading. Signal And Wait.

Semaphores are often confused and characterized as just a more general form of a mutex. There are actually some big differences though.

May 04, 2016•13 min

100: Multithreading. Master The Lock.

This episode dives deep into locks. How do they work? And then explains how you can use this to implement a reader-writer lock.

May 03, 2016•13 min

99: Multithreading. Cache Lines.

If you are not careful, you can cause a processor to come to an immediate and full stop while it waits for data to move around in memory. That is probably not the performance boost you were looking for.
