Word autocorrect can be a lot like emacs abbrev-mode


Tired of typing the same stock phrases over and over again in Word? You can use a stand-in word and global search and replace when your document is finished but it's a lot more fun to watch Word automatically type for you.

For example, if you add an entry to your autocorrect dictionary as shown above, every time you type the key qnato, Word will instantly replace it with North American Treaty Organization just like emacs abbrev-mode.

If you have different groups of abbreviations for different kinds of writing you can prefix them all with the same letter or number and they will stay grouped and separate in the Word autocorrect dictionary.

Some general ideas for using this would be:

   @gg = @gmail.com
   @yy = @yahoo.com
   @me = your.name@bigcorp.com

You can also highlight an entire block of text and the entire block including all formatting can be assigned to an autocorrect  key. This would be useful for having various signature blocks, addresses and boilerplate sentences and paragraphs for business letters.

And the last thing you can do is select a photo or picture in a Word document and add an autocorrect key for it. For example if you paste a picture of The Dude into your document and add the key dude for it, every time you type dude, a picture of The Dude will be inserted.

Teachers can use this for easy clip art insertion. Any bit of art that is regularly being inserted into your documents can be assigned to a key.

You can build a dictionary with an image for every number and letter if you want for puzzle construction.

If it turns out that this a seldom used feature of autocorrect I would worry about normal.dot corruption if the images are large, especially since the art is probably stored in normal.dot.

Samsung SyncMaster 204B Power Supply Repair

Samsung SyncMaster 204B PSU PCB


The SyncMaster 204B is a very nice 20.1" UXGA (1600x1200) panel circa 2006.
I really like this aspect ratio but everything has gone widescreen and a monitor like this is basically no longer available.

The CapXon caps bulge and fail and before complete failure the monitor flickers more and more since the caps are on the switching power supply that powers the backlights. I think only the three caps after the chopper were bulging on this unit.

See: http://en.wikipedia.org/wiki/Capacitor_plague

Opening the monitor is a PITA and you don't want to do it twice so replace all the caps the first time. Use flush cutting side cutters to cut away as much of the leads and solder as you can. Solder wick rubbed with flux and pressed into what remains will loosen the caps to the extent that they will almost fall off the PCB.

A proper parts list is a stumbling block for some people. These parts are perfect for my board rev 0.1 as of December 2011. These are not the cheapest possible parts but the parts with the longest lifetime ratings.
