Udev is a device manager for the Linux kernel and can be of great help to trigger activities when devices are added or removed. Once such scenario could be to run a script when the user connects a USB memory stick.
The first thing necessary to write udev rules is to have information about the device to create filters. However, I had a hard time finding information about what filters were available when I wanted to write a set of matching rules that would not cause a number of false triggers. To do this use the following command (replacing the device name to whatever device you want information about):
udevadm info -a -n /dev/sdb1
The following is an example of a command that can be used to run a script whenever a USB device is inserted.
The parameter %k to the script will be converted by udev to the device that caused the event. Note that the line is wrapped here but must be stated as a single line in the system.
After a hiatus of a couple of years I have recently come back to working with Windows servers – besides OS X and various Linux distributions, which have been my usual working tools lately. I realised that my old tools to access Windows servers would no longer do the trick. The Microsoft Remote Desktop Connection Client for Mac was never really very good but I had become used to Cord and it, too, would no longer work.
Apparently the problem is due to a difference in protocols between the client and the server and the two couldn’t negotiate properly on what protocol to use. I first tried to modify the server to default to the old RDP protocol and not try TLS. I even kept a virtual Windows client at hand to run whenever I felt a need to connect to a remote Windows server.
It turns out the absolutely best solution in these cases is to use the Microsoft Remote Desktop app, available on the Mac App Store for free. It is truly a great application for this purpose and allows the user to keep a list of servers and connect to them quickly and easily. For the ultimate in user experience, run the Windows terminal full screen and use the three finger swipe to quickly switch between the remote server and the local OS X system. Sweet!
