Using keywords to refine a windows explorer search

If you want to filter on a property that doesn't appear when you click in the search box, you can use special keywords. This typically involves typing a property name followed by a colon, sometimes an operator, and then a value. The keywords aren't case sensitive. 

Example search term	Use this to find
System.FileName:~<"notes"	Files whose names begin with "notes." The < means "begins with."
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.
System.Size: <1mb	Files that are less than 1 MB in size.
System.Size: > 1gb	Files that are more than 1 GB in size.

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.
