One:

“I have the largest seashell collection on the planet. I keep it
scattered on beaches around the world.” – Steven Wright

Two:

Coveting possessions is unhealthy. Here’s how I look at it:

All of the computers on Ebay are mine. In fact, everything on Ebay is
already mine. All of those things are just in long term storage that I
pay nothing for. Storage is free.

When I want to take something out of storage, I just pay the for the
storage costs for that particular thing up to that point, plus a
nominal shipping fee, and my things are delivered to me so I can use
them. When I am done with them, I return them to storage via
Craigslist or Ebay, and I am given a fee as compensation for freeing
up the storage facilities resources.

This is also the case with all of my stuff that Amazon and Walmart are
holding for me. I have antiques, priceless art, cars, estates, and
jewels beyond the dreams of avarice.

The world is my museum, displaying my collections on loan. The James
Savages of the world are merely curators.

Number three: Watch www.aetv.com/hoarders for a few episodes and that might cure you!

If you need to select the whole data region (it might included some empty cells) in Excel without selecting all cells (<CTRL>+<A>), click on any cell inside that group and then type: <CTRL>+<SHIFT>+<8>. It is very useful for large data sets.

You should then get something like this:

1. Type about:config<ENTER> in firefox address bar
2. *Optional* Type: mousewheel.withnokey<ENTER> in the filter box
3. Set mousewheel.withnokey.sysnumlines to false

   This makes Firefox use its own setting instead of the system-wide setting.

4. Change mousewheel.withnokey.numlines to how many lines you want to scroll at a time.

I use 8

The following resources allow you to edit any web page and print only what you need to save paper and/or ink.

• Bookmarklets

  To use a bookmarklet, you need to bookmark it; either drag it to your bookmark toolbar or right click the link and choose bookmark this. Next, when you visit a web page you would like to edit, click on that new bookmark. My favorite one is PrintWhatYouLike, there is no extension to install and it is a very easy and efficient.

  2. EditThis Bookmarklet (Demo)
  3. List of bookmarklets to remove (zap) annoyances from web pages

This example Bash script replaces “.JPG” with “.jpg” recursively in the current directory (It can handle filenames with spaces):


#!/bin/bash

find ./ -type f -name "*.JPG" | while read FILE
do
newname=`echo $FILE | sed s/.JPG/.jpg/`
echo $newname
mv "$FILE" "$newname"
done


Convert all characters to lowercase:


#!/bin/bash

find ./ -type f -name "*" | while read FILE
do
newname=`echo $FILE | tr 'a-z' 'A-Z'`
echo $newname
mv "$FILE" "$newname"
done


For example, you have 2 sheets, Sheet1 and Sheet2: they both have a list of part numbers in column A and a list of prices in column B. You want to compare the prices for the same part numbers in each sheets. One way to do this is to copy the prices from Sheet1 to Sheet2 in a third column and then use conditional formatting to highlight the different prices:

Copy this formula in cell C2 of Sheet2 (and then drag it down to the cells below):
=INDEX($Sheet1.A$2:B$3001;MATCH(A2;$Sheet1.A$2:A$3001;0);2)

This formula assumes that there is a maximum of 3000 different products in Sheet1 (starting at cell A2).

“ReNamer is a very powerful and flexible file renaming tool, which offers all the standard renaming procedures, including prefixes, suffixes, replacements, case changes, as well as removing contents of brackets, adding number sequences, changing file extensions, etc. For advanced users, there is a PascalScript rule, which let users program their very own renaming rule.

In addition, it has an ability to rename folders, process regular expressions, Unicode capable, and supports variety of meta tags, such as: ID3v1, ID3v2, EXIF, OLE, AVI, MD5, CRC32, and SHA1.”
