After getting files from a remote source, it is often a good idea to get some sort of fingerprint or checksum of the file, and verify it against a known value published in a place or on a website you trust.
For Windows, this can be accomplished with:
certutil -hashfile filename.ext sha256
sha256 can be any of MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

This does not seem to be a problem for everyone nor for every XFCE theme, but sometimes it can be a real drag (no pun intended) to resize the windows in XFCE / XFWM4. For no apparent reason whatsoever, this seems to be known by the developers but marked as “wontfix” … #WTF
Anyway, hold down the (left) Alt key (PC keyboard), right click the mouse and then drag in the desired direction to “easily” resize the windows. This is a lot easier with an actual pointing device rather than a “touchpad”, but at least there’s a way.
You can also use Alt+Space and then press R to resize the current window.
This sort of “behavior” is one of (many small) things that annoys and frustrates people with “Linux Desktops”, and in all honesty, this should not be an issue in 2019! #FFS
ALT + [RIGHT-CLICK] + DRAG
ALT + [SPACE] followed by the [R] key
Overwriting “unused space” on Windows 7, Windows 8, and Windows 10 is quite simple. Open a “Command Prompt” window, and type:
Where “DD” is your drive without a suffix, e.g.
to wipe unused space on drive C.
Why is this useful? Well, when you delete files from most modern operating systems, they aren’t really erased, even after you “Empty the trash”. The file system on your drive is simply updated to indicate that the space previously occupied by the file is now available. But the file data is still there. Overwriting such “unused space” with nonsense/garbage data will make it harder to recover the file data.
There’s another utility program from Microsoft called SDelete that has been around for quite some time. It goes about things slightly differently, but may do the job as well as cipher. You can find SDelete here.
If you, like me, are using Ubuntu – or similar – for your daily stuff and need to connect to a Windows Server by using RemoteDesktop (RDP) / TerminalServer, you may find that local (Linux) resources are not made available to you on the Windows side.
The Remmina client on at least Ubuntu 14.04.LTS is very outdated. Go grab the latest version directly from their site. Installs without issues and gives you a “somewhat” more up-to-date RemoteDesktop Client for Ubuntu Linux.
