Dr. Glenn Wilson, a psychiatrist at King’s College London University, monitored the IQ of workers throughout the day.
He found the IQ of those who tried to juggle messages and work fell by 10 points — the equivalent to missing a whole night’s sleep and more than double the 4-point fall seen after smoking marijuana. [Dr. Wilson did not originally make the comparison to marijuana. – eds.]
“This is a very real and widespread phenomenon,” Wilson said. “We have found that this obsession with looking at messages, if unchecked, will damage a worker’s performance by reducing their mental sharpness.
“Companies should encourage a more balanced and appropriate way of working.”
Wilson said the IQ drop was even more significant in the men who took part in the tests.
Glory be! It’s pretty easy to get nicely formatted output of those sneaky HTML e-mail messages (which all the young Internet kids are sending nowadays).
~/.mailcap, if you use w3m (as I do):
text/html; w3m %s -o display_link_number=1; nametemplate=%s.html
text/html; w3m -dump %s -o display_link_number=1; nametemplate=%s.html; copiousoutput

I archived a directory. It took two hours, then exited with a non-zero exit status (that means an error). Hmm — I was just testing something; I only cared if certain specific subdirectories were present in the archive. So I needed a way to look deep inside, quickly, and find those particular directories.
GNU tar will let you “test” an archive with -t, but I only wanted a list of the directories archived. Then I wanted that sorted. So…
$ nice tar -tjvf data.tar.bz2 | tr -s ' ' | cut -d' ' -f 6- | cut -d / -f -2 > tardirs.txt
$ uniq tardirs.txt > tardirs_uniq.txt
$ sort tardirs_uniq.txt > tardirs_uniq_sorted.txt
The -tjvf arguments to tar let you look inside, the “tr” command collapses adjacent spaces so that the first “cut” command will output only the sixth (file) field, and the second “cut” command will reduce a directory like “folder/folder/folder/fun.txt” to “folder/folder.” Then “uniq” will remove non-unique names.
Have you put together an OpenOffice.org table in OpenOffice.org Calc, and wanted to display alternating backgrounds for easy reading? Well, there’s an easy way to do it.
The steps are:
- Create a style for every other row and call it “Even rows.” Make its background “Gray 10%,” or whatever other color and attributes you prefer.
- In your spreadsheet, select the range of rows you’d like to format.
- In the Format menu, click “Conditional Formatting…”.
- Choose “Formula is” in the first dropdown.
- For the condition itself, enter the formula
ISEVEN(ROW()). This formula tests if the current row in question is even or not. If it is, the condition is met and your style is applied.
- For Cell Style, select the style you created back in Step 1.
- Click OK. There you go.
Okay, so you very likely have the ‘split’ utility installed (it’s in the GNU coreutils package, so… very likely). If you want to burn a file to multiple media, but you don’t have kdar installed on your desktop… don’t worry about it. Just open a terminal and do:
$ split --bytes=600MB --numeric-suffixes filename.zip filename_part_
In my case, I have a 2.8GB file, but I only have 700MB CDs on hand for my burner. So this command will ensure that I get several 600 “megabyte” (1000 bytes * 1000) pieces, named “filename_part_00,” “filename_part_01,” and “filename_part_02,” et cetera.
Are Distractible People More Creative? Jonah Lehrer, Wired Science
He says it right: “We need to be ruthless about throwing out the useless stuff.”
How do great authors write? And great painters paint? They focus. Distraction might flit an idea in your face, but it doesn’t have the power to lead anyone to great production. Just more distraction and dissipation.
Discipline, however, plays a much greater role:
