Java Dynamic Arrays

As you may know, arrays in Java are not dynamic by default, so you will have to implement ways to make them that yourself. You CAN change the elements in an array but you CAN'T change the size ( add or remove ) elements after the array has been initialized. In this post I will show you how to change arrays dynamically by using some methods.

Advanced Notepad

Notepad++ is a sophisticated version of a simple notepad that we all know and love. Actually it differs very much from it. You can check the features list at the end of the post. Here are some pictures to see what the software looks like.

If you don't have the time to add your own language settings then you can simply get the one you like that are made by other people from here (yes, the settings can be shared which is awesome). There are a list of extra plugins for Notepad++ that may interest you in here.

Difference between 32-bit and 64-bit

When we talk about bits, we talk about binary digits. 1 Bit is a unit or information in computing which has a value of 0 or 1. In this post I explain the difference between a 32-bit and a 64-bit system. Having a 32-bit system means that you need to have a 32-bit processor, buses and have to be using 32-bit software, but there are also ways to compute different bits with certain tools.

The bits show the width of the data buses, address buses and registers in a system, which means that 64-bit is wider than 32-bit. A 32-bit register can hold up to 2³² values and the same is with the 64-bit registers, which makes 2⁶⁴ different values.

Finding Your IP Address

What is and IP address?

IP ( Internet Protocol ) address is and identificator that each computer and network owns. Computers use IP address to communicate with eatch other.

Public and Private IP

There are actually 2 IP addresses. Public is the one your network (router) has, which is used on the internet. Private is the one that your computer has, which is used locally in your private network.

SSD vs HDD

How do they work

HDD uses a writer/reader attached to a mechanical arm which moves very fast to the right location of the disk to read or write data while the platter ( where the data is stored ) spins also very fast, normally 7200  revolutions per minute. The technology in HDDs is magnetism.

SSD uses the NAND flash technology ( there is no mechanical movement involved ) which takes less time for gathering data than HDD that has to look everywhere on the disk and find the data blocks ( they may also be spread out on the disk which makes the search even slower ). SSD is just a bigger and more advanced version of a memory stick. There is a embedded processor inside SSD and it controls the data manipulation ( caching, cleaning, storing, retrieving ).

Restore Windows With Restore Points

In Windows there is a tool called "System Restore" and it can be a very valuable asset when having a problem such as driver or registry problems. Even sound and other system settings/options are fixed.

How does it work

Windows automatically creates restore points (before each installed program or driver) which can be later used to restore your system files and settings to that point in time. Your personal files (photos, documents, emails) will not be affected. Restore points can also be created manually.

You can also undo the changes done by system restore. Useful if it didn't fix the problem.

How To Change Your Hard Drive Icon

How To Check Your Computer Temperature

Checking your computer component temperatures once in a while is recommended. Knowing whether your coolers work efficently enough is important. The temperatures greatly depend on what CPU and GPU you have and under how big load your computer is. Your current environmental temperatures can also affect your hardware by ~5°.

Normal temperatures for your hardware ( CPU and GPU )

On Idle

Desktop   ~40°C   ( 104°F )

Laptop   ~50°C   ( 122°F )

Under Heavy Load

Desktop   ~60°C   ( 140°F )

Laptop   ~70°C   ( 158°F )

How To Use Multiple Monitors

How does it work

You can display the same picture in all the monitors, but usually multiple monitors are used as extended displays, making the desktop larger. In extended mode, depending on how you position your displays, they act as one big desktop, it means that you move with your mouse from monitor to monitor the same way you normally move with your mouse, just by moving it around.

All the programs and windows act the same way as normally, you can drag them from one display to another or extend the size of your window over by multiple displays at the same time.

JUnit Testing In Java

This is a little tutorial on how to use JUnit tesing ( JUnit 4.x ) in Eclipse. First you need to add the JUnit library to your project path and import it in order to use it. I'm also going to include an example in this post.

Why use JUnit test

The best reason for testing your code is that you can find your bugs and errors early and you don't have to burden your head later when you have already put it all together. It can save a lot of time in long-term. If you have a lot of code to cover and change it often, testing it is very recommended.
