Invert your screen

oneshot · #1 04-09-2009, 03:21 AM

I just wanted to post this for anyone that didn't know yet.

If you hold "Control" "Option" and "Command" and then press "8"

It inverts your screen.

Just press it again to change it back.

Its fun to do this to your school computers because the computer teacher thinks its a virus and has no idea how to change it back =)

(I know from experience)

Like physically flip the screen upside down? or is there a key combo or easy way to do that?

Well, it` one of the Universal Access functions. There`s a whole list of keyboard shortcuts in Settings under the Mouse&Keyboard section i guess. Pity that there`s no shortcut to fast user switching like Win+L in Windows. Or at least i dont know about it hmm. Anyway, i dont think there`s key combo to rotate the screen. In Windows i think it`s quite easy with nVidia or ATI drivers with shortcuts.

Heh, as I was in school we had a bunch of 286's with green-display monitors... If you'd have hang an X-ray film in that room you got a picture after a while

Somedays we had a teacher who had no idea about computers, but we could go in the computer room as there was spare time. Then someone programmed a little batch file which made some PC beeper noises and printed a message 'Error: Water in drive A: Please contact support'. The teacher flipped out because he had no idea what to do

As I got in school the first time the MS-DOS ASCII Escape sequences (Control sequences) I wrote a little batch that changed the DOS resolution to low-res, the color to blue/light blue and printed a new starting message: "**** COMMODORE 64 BASIC V2 ****"

Adding to autoexec.bat and you have some fun...

Some years later I tested some other MS-DOS batch things, and you can do some really nasty things with it. For example, a recursive batch that creates an infinite directory tree. If you delete the MS-DOS command DELTREE.COM you had to go manually (1000x CD) to the absolutely last directory, and then delete it normally.

Another thing is a batch which uses the text output redirection to a file, like "type >outfile.txt readme.txt". If you use >>outfile.txt the output will be added to the end of that file. If you create an endless loop like "type >>giantfile.txt giantfile.txt" you will create a file which exponentially increases its size! On modern computers you can fill in seconds gigabytes of harddisk space with this - only with 4-line batch file!

The screen invertion thing I had somehere else: Actually In Germany Apple computers are available at 'Kaufhof' which is a normal department store chain (hope this was the correct word), they aren't a specialized computer store. There was an iMac with mouse and keyboard, and Tiger installed. I played a bit with it, them some guy came and asked 'May I can help you?'. After a little chat I noticed that he had no idea from Macs, and I showed him some things - Terminal, Speech recognition, Photo Booth and different other things. And the screen invertion thing. The guy was absolutely impressed of the capabilities of a Mac, perhaps no one told him that although he should sell these things. As I was going, I could see from the escalator that he was showing the invertion trick to a collegue...

classic example of the blind leading the gormless lol. I love ppl that profess to know things they dont rofl. I had a salesman try and throw me out of a shop once years ago for telling a bloke he was making a very over priced choice on a branded system that was crippled and lame for the money. I dont think I ever found anyone get as angry so quickly as the salesman did that day. Ha Ha Ha. Coming to think of it I even offered to build the bloke a system. With huge savings as you could back then

Well, no wonder why he tried to throw you out haha

But that`s quite common everywhere. I tried to buy ZIP disks someday ago, and of course salesman asked me how many, - i dont remember how many i wanted and what i answered but there he goes - he brings me a pack od 10 FDD disks lol, when i told him i wanted ZIP ones, he said that he dont know if they have them ( of course at this point i knew it was rather "WTF is this ZIP thing ?" ) and went to ask the manager. Well...i didnt get any of ZIP disks that day, but man, what i got was a lot of fun

As I heard the word ZIP I immediately remembered this comic strip... Maybe just funny for me and Lawless

I'm using JAZ drives on the Amiga. With 2 GB size and SCSI connection they are acceptable fast and the space is enough for Amiga data storage. But the disks are getting a bit old.

Hahahaha. I absolutely love batch files. I didn't really understand the growing file one you were talking about though? I used to know soooo may batch commands back when I used to be on Windows all day. I knew this one that would completely wipe your C drive =)

I might post the batch commands if I can find them again =D
