Unit conversion in Spreadseets
Filed Under Howto, Linux, Windows | Leave a Comment
Recently I had to create a table to convert from lb to kg.
The way I did it was to start spreadsheet program – Excell or OpenOffice.org and fill up the conversion formula and desired data range.
1. In a cell fill the conversion in my case 1 lb = 0.453592 kg I used cell B1
2. Fill up a column with desired data
3. in next column type the formula =A3*$B$1
4. Copy the formula to other rows
5. Done
This method could be used for other conversions just by changeng the value in B1

Random name folders in Windows
Filed Under Fix, Windows | Leave a Comment
After updating my Windows machine I found that few folders with cryptic names are created in root directory.
They look like this:
28/12/2006Â 07:33 PMÂ Â Â <DIR>Â Â Â Â Â Â Â Â Â 1822a56c32dc8dbcf5 11/02/2009Â 09:42 PMÂ Â Â <DIR>Â Â Â Â Â Â Â Â Â 89b3b50a7b1b96838a89 30/08/2007Â 06:19 PMÂ Â Â <DIR>Â Â Â Â Â Â Â Â Â a8ccd1e2d466bc402f
I’m used to the folders created after update in \WINDOWS and after I’m sure that there is no problems with the update they could be safely erase, but this was something new.
After browsing the contens my initial thougths were confirmed those were temporary folders from windows update.
So I erased them…

Make FreeBSD more “user friendly”
Filed Under Command line, Unix | Leave a Comment
In FreeBSD by default you do not have bash as shell prompt.
Here is the procedure to install it:
- type whereis bash
- cd to that folder
- type make configure
- make all install clean
- take a cofee 😉
- type chsh -s /usr/local/bin/bash root to change the shell for root or replace root with username you want to change the shell.
- Then relogin (logout and login) to enjoy bash shell

I had a strange problem when trying to list all files i a folder.
I typed:
find . *.gz
And received:
-bash: /usr/bin/find: Argument list too long
After searching on internet I saw a lot of similar problems, but then I remembered one of my old posts
bash: /bin/rm: Argument list too long – How to fix it
After reviewing it for on more time I found my mistake
Correct syntax is:
find . -name "*.gz"

Print envelope with OpenOffice.org
Filed Under Howto, Linux, Windows | Leave a Comment
In the era of e-mail and internet less and less people use regular mail, but sometimes you need to send a letter to someone.
Typing the address can be annoying and sometimes unclear so let’s put your computer to work.
To print your and recipient address on an envelope you can use manual formatting on a page, but if you follow the instructions here the process will be more automated.
So what we need:
- Printer – you want to print with something
- Envelopes – and something to print on
- OpenOffice.org (OO) – and some tools
Note: If you have MS Office you can use it too. See at the end…
1. Start OO and create empty document in writer
2. Go to Insert -> Envelope
You will see similar window:
Add your address (if it is not already filled in) and Recipient address.
3. Select envelope format
Next click on Format tab
Choose your envelope format and addresses positioning
4. Setup your printer
It is not done you need also to setup your printer. Click on Printer tab:
Select correct envelope orientation and setup your printer to use envelope as paper and correct paper source (usually manual feed).
6. Ready to Print?!
When you are ready click on New Doc.:
Here you can add your logo and preview how the envelope will look like.
When you are sure it is OK just print it.
First few times you will be on trial and error, until you correctly print, but after will be straightforward.
For Microsoft Office users:
If you have Office it is not obligatory to download ind install OpenOffice.org.
The procedure is similar, but on step 2 you go (at least in MS Office 2003) to Tools -> Letters and Mailings -> Envelopes and Mailings…

GPU acceleration in Acrobat – Take 2
Filed Under Howto, Windows | Leave a Comment
Or the benefits of upgrade…
As already mentioned in my previous post Adobe added 2D acceleration in Acrobat reader in version 8. Unfortunately for me that feature was not available for the card in my laptop.
Today I’ve decided to upgrade to v 9 and for my surprise 2d acceleration was available and turned on by default.

Fixing vim/vi arrow keys behavior
Filed Under Fix, Linux | 3 Comments
In case your arrow keys do not work as usual when you enter in “insert” mode try this:
:set nocompatible
And if this fixes the problem add:
set nocompatible
to your ~/.vimrc file.
I had this problem in FreeBSD 7.0 and this fixed it.
Found here.
