Programming with FASM – test with CPUID .

First you need to take a look at this website.
The CPUID returns processor identification and feature information in the EAX, EBX, ECX, and EDX registers.
What the source code from my example do ?
First I start with the default assembly program .
The next step is to strat with reset xor eax,eax use cpuid.
The result of CPUID will be put into EBX.
Into section ‘.data’ data readable writeable make a structure named out_buffer.
The structure will be fill so you need to EBX, see example:
mov [out_buffer.vendor_ebx],ebx will give us “Genu”.
The next step for test EBX is this example:
test edx,00010000000000000000000000000000b
jz .NoHTT
mov [out_buffer.htt_arch4],’YES ‘

The structure of out_buffer is :
db ‘NoHTT’,2,9,’- ‘
.htt_arch4 dd ‘NO ‘
db 9,10

Because I used MessageBox to show us the out_buffer.
The result will be : No or Yes with the size of dd.
The db can define byte variables, as well as arrays of bytes.
Fasm documentation tell us: For example db 1,2,3 will define the three bytes of values 1, 2 and 3 respectively.
The dd has 4 bytes.
The result will be this text (the result is true so the text will be YES): “NoHTT – YES”.
Let’s see one screenshot:

This is the source code:

Windows 10 – sc command .

The sc command help us to retrieves and sets control information about services.

Some options of this command:

Let’s test query with intelhaxm:

To create a list of all services used:

You can use : start and stop to start and stop services.
The start option come with has one of the values auto, demand. or disabled.
Using administrator command shell you can see the RPC Services:

C# – First steps with C# and .NET – part 002 .

Today I will show you more about C# and the subject of this tutorial is: threads.
First you need to start a project into your folder. Let’s see my example:

You can use notepad or any editor to edit the Program.cs:

About the thread issue then you need to know is a very complex subject.
My example will show you how the thread works.
First you need to start the thread and then deal with the thread.
Two methods is used: Start and Join.
Start begins executing at the first line of the method and does not block the calling thread.
Join is a synchronization method that blocks the calling thread (that is, the thread that calls the method) until the thread whose Join method is called has completed.
I used three threads and this threads just start count first 5 sec , next 8 sec and the last is set to 10 sec.
Let’s see the example:

Each thread will write to the output and then will see the time used.
See the output of dotnet run command:

C# – First steps with C# and .NET – part 001 .

First you need to take a look at Microsoft DotNET – Core website..
This website will be the start for any .NET and C# issue on any operating system Linux, Windows, Mac or Docker.
I used for this tutorial Windows OS and for Fedora distro you can take a look here.
First you need to

The result of Hello World! show us the console application works well.
This will run this program:

You can change the text Hello World or test something else.
If you got errors the you need to fix it with :
