OS

Supermicro X9SCI/X9SCA, video is gone!

As I am still trying to get my computers to work with a dual seat (or multiseat), I did an attempt in using the onboard video (a relatively decent Matrox card.) So I went in the BIOS and changed the setup for the video from Offboard to Onboard. Big mistake!

The video stopped working. On reboot the computer beeped 8 times and booted the OS normally (I have SSH setup so I could access the computer, but absolutely no video on either port: on board and off board.)

I have a Supermicro X9SCI/X9SCA. Searching for "no video" or "missing video on boot"... returned nothing ...

md5sum for MS-Windows

Today I needed to test a transfer from a file system to another making sure that a 750Mb file was being tranfered correctly. For this I wanted to run an md5sum on the file from the native OS (MS-Windows) and then on the target OS (Linux).

I found a nice utility that worked right in and returned the correct result (what I'd expect.)

Taking a Screenshot on Mac OS/X

In order to take a screenshot on your Mac OS/X system, simply type "Apple-Shift-3". Then you will see an image on your Desktop. As far as I know you cannot control where the image will go.

There are many other combinaisons that let you select the part of the screen you want a screenshot of.

The name of the file on your dekstop is "Picture #.png" where # increases as required. Although since 10.4 you can change the file format with a Unix command.

The Conduit Toolbar

Today I tried a new system. It lets you create a toolbar for your browser. One thing that impressed me was that it worked for Internet Explorer and FireFox and runs under MS-Windows and Mac OS/X, but also works beautifully under Linux!!!

Note that SeaMonkey will ask you whether you want to install that software and it will fail since it has some features like FireFox but the installation process is different.

Now, I like the bar for one reason: I can put RSS feeds in there and see it tick. Only problem there, it goes too fast.

Register an application so it automatically starts on reboot

Always wondered how they automatically restart an application after a reboot under MS-Windows?

There is a function named RegisterApplicationRestart() that does just that.

There are flags to tell when your application should be started or under which circumstances.

For instance, you can start only if something crashed the OS.
