Conditional Formatting In Open Office Calc.
First, we need a new formating style.
To do this we need to pick any cell in our sheet and apply what style we want. For this example, I chose to set the background color to yellow. Then, on the Format menu we need to click
Styles and Formatting.
The Styles and Formatting box now appears. Then click on the New Style From Selection Button.
When the Create Style box comes up, you can name your new style. I called mine yellow.
Now highlight your data that you want to apply the conditional formatting to. Then on the Format menu, click Conditional Formatting. I decided I wanted to highlight the values between $20,000 and $28,000.
After you click OK, your data is highlighted.
The data is prices on makes of different sports cars that I made up. To generate the data, I used the RANDBETWEEN() function.

How to insert a graph into a spreadsheet
After you have installed Graph, open Calc.
Goto Insert > Object > OLE Object... and you will get a box like this.
You then need to double click Further objects. You will then get this box.
Once this box is up, you need to click on Graph System and then hit OK.
This will show on your screen. It might show you a tip of the day. You can just close that.
You can then enter the function you want to graph and then close the graph window. And there you have it. A graph.
I have a video on You Tube explaining this. The video is done with Excel 2007. Below is the link. Enjoy.

MINVERSE and MMULT
Functions used:
MINVERSE(Array)MMULT(Array,Array)
Let's look at each function individually:
MINVERSE(Array) - This function calculates the inverse of a square array. Square array means the array has the same number of rows as it does columns.
MMULT(Array,Array) = This function calculates the product of two arrays. The number of columns in the first array must be the same as the number of rows in the second array.
Take a look at the screen shots below. I have posted this file. It is called system of equations. You download by clicking on "Spreadsheet Function Files" under "Links" on the right hand side of the page.
This screen shot is for cells A13:C15
This screen shot is for cells B18:B20
And here is a screen shot of my results. The answers are in cells B18:B20

What do I do? Excel freezes up.
Problem:
You open excel, it freezes up your computer and says there is not enough memory.
Fix:
Uninstalling excel will and reinstalling will not fix this problem. More than likely, the menu file is corrupt. With excel closed, open windows explorer and do a search for ".xlb" without the quotes. This is your menu file. Once the file shows up in the search, you need to delete it. The file you are looking for is Excel.xlb. Close windows explorer, open excel, and it is fixed.

EBay strengthens PayPal's anti-fraud provisions
EBay executives said Thursday at the company's annual user conference that buyers who pay for items with PayPal will be eligible for full refunds, with no cap, if a seller fails to deliver an item as promised. Previously a buyer's coverage was capped at $200, or $2,000 if the item's seller enjoyed a particularly good reputation on eBay.
EBay sellers who accept PayPal as a payment method — as nearly all of them do — will also get unlimited protection against a charge being reversed.Fortunately, I have never had a problem with paypal. Woops, I better knock on wood.

Snake in the road
Switch Pitcher?
Things got a tad dizzying when designated hitter Ralph Henriquez, who had taken his on-deck circle swings as a lefty, entered the batter's box from the right side.
Venditte put his specially made glove (it has six fingers, two webs and fits on both hands) on his left hand, and got ready to pitch right-handed.
Python in the toilet
This is not the actual snake. This is just some random picture.
Be careful when you go to restroom. A 6 foot python slithers out of a 10th floor apartment toilet in Australia.
"When I saw it I was pretty shocked," Peberdy told the Northern Territory News. "It's one thing in the Territory to have a green frog in the toilet ... but not a six-foot python. It would certainly scare you if it came up from the depths of the toilet.”
I think it would scare me also.

I am Back
We went to the in-laws and had a wonderful lunch. We had beef cube steak smothered in gravy and rice. It was delicious.
Finally, we got in the truck. We started our venture to get the RV, which was about 45 minutes away on another lot my in-laws own. Everything was going great. We were having a great time.
Now we arrive at the lot where the RV is. So we have a few things to get cleaned up. There was debris on the roof that we had to get off before we could retract the sides back in. The water and sewage line also had to be unhooked. My mother in-law and wife were inside securing loose items. After about an hour, everything is ready. So we hookup the RV and we are off to our destination, Stamps, Arkansas (about 2 hour away).
Now the real fun begins. The tires on the RV need air, so we stop at the store and air pump (I was shocked that air costs 75 cents now) does not work. No big deal, we will just stop and next station a few mile up the road. Next, we pull into station number 2. Yeah, the air pump works and it is free air. I start airing up the tires and my father-in-law is check the air pressure. All of a sudden we here bam. The valve stem broke on one of the tires form being dry rotted. We get the jack and spare tire and after about 20 minutes we ready to go.
With everything ready and aired up, we are off to Stamps. We are cruising along when all of a sudden a lady pulls up beside us and starts pointing. So we pull over onto the shoulder of the road. OH ****!!! A tire blew out!!! Wondering what we are going to do, this nice man pulls up and asks us if we need any help. And guess what? He owns a tire store. It takes about 1 1/2 hours to fix the tires and get back on the road.
We finally arrive at our destination. Nothing else happened. The only other thing we did was eat at Burger King. Then we finally arrived back home about 1:30 a.m.

Trying to take over Anheuser-Busch
That's just one of many reasons beverage sector experts -- and more than a few Bud drinkers -- are rolling their eyes at an audacious play by Belgian brewery giant InBev for Anheuser-Busch (BUD, news, msgs). The St. Louis company makes the iconic Budweiser brand that's as American as hot dogs, baseball and apple pie.

Don't tail gate drivers with bumber stickers
I used to think that the most dangerous thing about bumper stickers was that they make curious drivers inch ever closer to the car in front of them in order to read the things (“He Put the Duh in W,” perhaps, or “At Least the War on the Environment is Going Well,” or “49% ***, 51% Sweetheart; Don’t Push It,” or “If There Is a Tourist Season, Why Can’t We Shoot Them?”—for all of which I am indebted to http://www.bumperart.com). But no, bumper stickers pose another danger: drivers who plaster their vehicles with the things are more prone to road rage than drivers who leave their car or truck unadorned.

ATANH(number)
number represent the cosh, sinh, or tanh of a number.
The number you are taking the inverse hyperbolic cosine of must be greater than or equal to 1.
