According to technet.microsoft website about IPv6 for Microsoft Windows:
IPv6 in Windows XP and Windows Server 2003 uses the “Automatic Tunneling Pseudo-Interface” for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. By default, IPv6 configures a link-local Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) address on the Automatic Tunneling Pseudo-Interface. The link-local ISATAP address has the form fe80::200:5efe:w.x.y.x or fe80::5efe:w.x.y.x, in which w.x.y.x is an IPv4 address assigned to the computer.
You can remove this with this windows command:
Remove tunnels adapter show by ipconfig command.
Programming with C# and Unity 3D game engine – part 001
This tutorial will cover the first steps programming with C#.
The C# is an more complicated language like another programming language.
Now, C# it is an object-oriented programming language like C++ or Java.
If you know this programming language then will be easy to you to use C#.
First in C# the entry point of program is a static function called Main inside a class, not more than one.
If you want to compile one C# program then you can use the compiler:
cc yourprogram.cs
… or just use the Mono IDE.
C# has data types, operators, variables, constants, typecasts, branching like any programming language.
Also C# allow you to create your own data types. This mean the C# is an extensible language.
Let’s see more about this:
- data types: bool,byte, sbyte, char, short, ushort, int, uint, float, long, ulong, double, decimal
- operators: +,-,*,/,%,++,–,*=,/=,-=,%=,>>=,<<=, bitwise, logical, shifting operators …
- variables: int my_var = 1;
- constants: const float my_const = 5;
- typecasts: C# need to know if is an explicit and implicit conversions.
- branching: if, switch, while, for, do-while, …
After you open the Unity 3D IDE the next step is to create the C# script.
Right click with the mouse into Project tab, like in the next image and simply create the script.
The default script is named NewBehaviourScript and come with this source code:
using UnityEngine;
using System.Collections;
public class NewBehaviourScript : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
} You can see the class NewBehaviourScript calls to the Unity Engine ( see: using UnityEngine).
Also two functions:
Start() – this is called when the scene first launches and Update() – This is called in every frame that the game runs.
Unity 3D will rewrite the class name in your C# script when you will rename your script in the Project panel.
You can create new scripts and also can be used to call different features of the game engine.
Foe example you can create one new script to move, rotate or scale one object from Unity 3D Engine.
The driverquery command take one inventory of your installed drivers.
If you want a compact record of installed drivers in a format that you can review later, use the driverquery command.
DRIVERQUERY [/S system [/U username [/P [password]]]]
[/FO format] [/NH] [/SI] [/V]
Description:
Enables an administrator to display a list of
installed device drivers.
Parameter List:
/S system Specifies the remote system to connect to.
/U [domain\]user Specifies the user context
under which the command should execute.
/P [password] Specify the password for the given
user context.
/FO format Specifies the type of output to display.
Valid values to be passed with the
switch are "TABLE", "LIST", "CSV".
/NH Specifies that the "Column Header"
should not be displayed. Valid for
"TABLE" and "CSV" format only.
/SI Provides information about signed drivers.
/V Displays verbose output. Not valid
for signed drivers.
/? Displays this help message.
Examples:
DRIVERQUERY
DRIVERQUERY /FO CSV /SI
DRIVERQUERY /NH
DRIVERQUERY /S ipaddress /U user /V
DRIVERQUERY /S system /U domain\user /P password /FO LIST I use this to list all my drivers like a list with /V arg to produce a detailed (verbose) listing.
driverquery /v /fo list > drvlist.txt You can use also with this output : “TABLE”, “LIST”, “CSV” .
Calibre – best application to read your books.
I wrote about this application because I used often when I read books, programming books or documentation
Calibre is an open source e-book tool that allows you to:
- organize your e-book library
- convert e-books to various formats
- interact with your e-book reader
- Library Management
- E-book conversion
- Syncing to e-book reader devices
- Downloading news from the web and converting it into e-book form
- Comprehensive e-book viewer
- Content server for online access to your book collection
- E-book editor for the major e-book formats
Also can be used with Windows , Linux , Macintosh or calibre portable build can be run on any windows computer.
This is one screenshot , you can also customize this application.
Remove old Wireless Network Profiles in Windows 8.1
You can access Wi-Fi profiles and this can be also a problem because your device saved Wi-Fi spots.
So this can be solve easy with this commands to show this profiles
netsh wlan show profiles and then remove the profile:
netsh wlan delete profile name="profile_wifi_name"
