Using keywords to refine a windows explorer search

System.FileName:="quarterly report"
Files named "quarterly report." The = means "matches exactly."
System.FileName:~="pro"
Files whose names contain the word "pro" or the characters pro as part of another word (such as "process" or "procedure"). The ~= means "contains."
System.Kind:<> picture
Files that aren't pictures. The <> means "is not."
System.DateModified:05/25/2010
Files that were modified on that date. You can also type "System.DateModified:2010" to find files changed at any time during that year.
System.Author:~!"herb"
Files whose authors don't have "herb" in their name. The ~! means "doesn't contain."
System.Keywords:"sunset"
Files that are tagged with the word sunset.

Emulierter Raspberry Pi unter Windows

Mit dem Emulator-Paket für Windows kann man ohne Installation, Konfiguration und Anstöpseleien weiterer Hardware sofort erste Schritte in der Welt des Raspberry Pi unternehmen – ohne tiefer gehende Linux-Kenntnisse. Dazu genügt es für den Anfang, das Archiv zu entpacken und die Datei start.bat auszuführen. Der Emulator Qemu öffnet ein Fenster und startet das Raspberry-Image (Raspbian). Im Fenster lässt sich der Bootvorgang des Pi verfolgen – etwaige Fehlermeldungen kann man getrost ignorieren. Das Hochfahren nimmt einige Zeit in Anspruch, der emulierte Pi läuft selbst auf schnellen Rechnern sogar etwas langsamer als ein echter Raspberry.

Windows 8.1 WLAN Hotspot Access Point with board instruments

Windows has with netsh command very useful instruments to enable a laptop or desktop WLAN hotspot to share internet access with tablets, smartphones or other laptops.

("Internet Connection Sharing" must also be enabled for the selected adapter.)

Here is the description of the netsh hosted-network description:
 
C:\WINDOWS\system32>netsh wlan set hostednetwork
One or more parameters for the command are not correct or missing.

Usage: set hostednetwork [mode=]allow|disallow [ssid=]

                         [key=]
[keyUsage=]persistent|temporary

Parameters:

    Tag             Value
    mode            Specifies whether to allow or disallow the hosted network.
    ssid            SSID of the hosted network.
    key             The user security key used by the hosted network.
    keyUsage        Specifies whether the user security key is persistent or
                    temporary.

Remarks:

    This command changes the properties of hosted network, including: SSID
    of the hosted network, allow or disallow the hosted network in the system,
    and a user security key that is used by the hosted network.


    The user security key should be a string with 8 to 63 ASCII characters,
    eg. a passphrase, or 64 hexadecimal digits which represent 32 binary
    bytes.


    If keyUsage is specified as persistent, the security key will be saved
    and used when the hosted network is started again in future. Otherwise
    it will be used only when the current or next time the hosted network
    is started. Once the hosted network is stopped, the temporary security
    key will be deleted from the system. If keyUsage is not specified, it
    is persistent by default.

    This command requires administrator privileges to allow or disallow the
    hosted network.

Examples:

    set hostednetwork mode=allow
    set hostednetwork ssid=ssid1
    set hostednetwork key=passphrase keyUsage=persistent


You can combine the parameters in one command.
The following shows a sample usage in order:

1. Settings for WLAN hotspot 

netsh wlan set hostednetwork ssid=myLaptop key=mySecretKye93 keyUsage=persistent

2. Start hosted-network

netsh wlan start hostednetwork

3. Check the status

netsh wlan show hostednetwork

4. Stop hosted-network

netsh wlan stop hostednetwork
