There are various posts on how to remove the Office 2010 “Shared Folder Synchronization” context menu using either the Windows registry modifications or the Office uninstaller. I prefer a cleaner solution which seems hard to find at Google, so it’s worthwhile mentioning it here.

Steps

The approach is to unload the DLL in question. The first step is to start a command prompt as administrator.

In this command prompt, type (assuming 64-bits Office — see comments for details):

regsvr32 /u "C:\Program Files\Microsoft Office\Office14\GROOVEEX.DLL"

Pasting is not good enough, since the command prompt will not swallow the quotes. Therefore, type it, or repair the line with the up-arrow after pasting. An example of how it looks like:

After executing the command, a dialog will inform you of the result. If you get an error, double check whether you opened the command prompt as administrator correctly.

Reloading

Reloading can always be done by calling regsvr32 as shown above, but without the /u flag.

(Aside: in Office 2007 this feature was called Groove folder synchronization.)

Sometimes you’d like to do X-forwarding over multiple hops. For instance:

Home ↔ Office gateway ↔ Office machine.

One way to automate this is with this Bash function:

sshx () {
        [ -z "$2" ] && return
        sudo ssh -Nn $1 -L 2200:$2:22 &
        sleep 1s
        PID=$!
        ssh localhost -XYC -p2200
        sudo kill $PID
}

Choose a random localhost port number; 2200 is merely an example here.

Then invoke with:

$ sshx passthrough_server destination_server

Since the snippet relies on Bash forking, it assumes you have set up SSH for public key based authentication with the passthrough server, and it will not ask for a password. Because SSH requires root privileges on your local machine to set up the port forwarding, your ~/.ssh/authorized_keys on the passthrough server must contains the public key of root from your local machine.

When travelling internationally in Europe by train, it pays off to consider with which railroad operator you book your ticket.

This post is about price differences between Deutsche Bahn and NS Hispeed.

Use case

For the the same ticket, more than a month in advance, both DB and NS were compared.

DB

NS Hispeed

Findings

Even though one would be travelling with exactly the same trains, there is a €53 price difference between the operators. In other words, a DB traveller could save 62% by booking via the NS for this particular trip.
