VHDL is one of the most famous design hardware description languages.

If you are interested to know how to switch on your first LED in VHDL, let's get started!

For this tutorial we are going to use the Altera DE1 FPGA board.
And we'll switch on LED 0 and 1, to understand how it works.

It may be possible that one day you said to yourself: "I would like to design my own schematics for my electronic integrated circuits".

But you didn't know how to start.

Let's see this by learning basics in this Eagle design tutorial.

How to read, sort and write a new file with a specific text file?
A great question, isn't it?

What about a Java example to show how to read a file, sorting it and writing the result into a new text file?

Let's see that in this tutorial with a classic exercise, to manipulate inputs and outputs files.

Sometimes you need to convert one uint16_t variable into two uint8_t.

As we manipulate binaries, it's impossible to do something like that: 0xAB + 0xCD = 0xABCD.

Indeed, the result of 0xAB + 0xCD = 0x178 because 0xAB = 171 and 0xCD = 205.

A classic way to deal with database, with Android, it's to use the SQLite classes.

What's unique in SQLite is that you don't need a server where running your database.
Indeed, everything is already inside your Android application!

And of course impossible to another application to read this database.

I think the MapType is certainly the most fascinating feature of GoogleMaps and also one of the most easy to understand and make alive in an Android application.

With one click it's possible to change the display of the map such as hybrid, none, normal, satellite or terrain.

Google made a new version of its famous Google Maps API, called Google Maps API v2.

Things are new, such as the OpenGL ES version 2.

But let's try to create an application, in this Google Maps API v2 tutorial for Windows 7 and less or more.

With Ubuntu 13.04, you certainly found out that there is, by default, only one workspace.

If you want more, there are solutions.

First of all enable workspaces, then change (if you want) the number of workspaces.

Let's see this in this tutorial.

By installing a Ubuntu guest with VirtualBox on Windows, you likely found a basic resolution, such as 1024*768.

Unfortunately, you have a screen with a 1920*1200 resolution, it's impossible to let this like that.

There is of course a solution to increase this basic setup, but with a maximum of 1440*1050.

After creating a software to count in binary, let's see how bit shifting works.

In this tutorial we are going to see how to turn on and off a single LED each time we will be using the left bit shifting.
