Take Up Code

Knowing where to send information through IP is not enough. You have to know how to reliably send information too.

Any computer or device that wants to communicate with the Internet Protocol needs an IP address to uniquely identify the device.

Why do we need a system for managing domain names?

It is almost a tongue twister to say them all. Do you know what they all mean?

There is more than just two letters difference. In fact, you can not really compare them at all. But you can use them together.

Like XML, JSON is also a way to represent data that is readable by both humans and computers.

XML was designed to solve two main purposes. To allow information to be stored and transported and to allow both humans and computers to read and modify the information.

You might be more familiar with APIs than SOA but they had another meaning not very long ago.

As you learn more about something, a strange thing happens. It becomes obvious how much more there is to still be learned.

Service Oriented Architecture or SOA for short can mean different things. At the core, is the ability to send a message over a network to an isolated destination for a specific business purpose.

Knowing where to spend your time and focus will help you finish projects without getting stuck in details.

Consistency, Availability, and Partition Tolerance are three aspects of distributed computing. And a fourth not included in the theorem is Latency.

Two-phase and three-phase commits will help you design solutions that need to work across multiple computers.

Computers rely on clocks. They coordinate everything. But the clocks on different computers can be slightly off from each other.

What can you do to improve your concentration?

Dividing work between multiple computers is sometimes the best way to solve a problem.

How do you concentrate?

nullptr represents a null pointer and while it has a value of zero, the type is not the same.

When should I create a new class?

Making code more readable sometimes means knowing where to put nothing.
