Cool! Several handy one-liners for use in Sed, the stream editor.
# double space a file
sed G# double space a file which already has blank lines in it. Output file
# should contain no more than one blank line between lines of text.
sed ‘/^$/d;G’# triple space a file
sed ‘G;G’# undo double-spacing (assumes even-numbered lines are always blank)
sed ‘n;d’
about 10 days ago a journalist from the Sunday Business Post rang asking me about Linux in TradeSignals. A brief interview followed, but then 2 days later a photographer called out and took a picture of me stuggling with a laptop while smiling bravely. I prefer being on the other side of the camera..
Those of you who didn’t buy the newspaper on Sunday are spared the picture of me, and the article (unfortunately), but there is an article about a CEO who tried Linspire on his laptop and was surprised to find it easy to install and use.
They also put their obligitory Microsoft FUD article online too which is a bit disappointing as it’s quite misleading and repeats the usual MS line. Oh well!
Later… This was mentioned on The ILUG mailing list on Sunday, and here too, along with some more thought about the pro-Microsoft article.
Via slashdot, I thought this thread on how swappy Linux should be would be informative but it appears to be very subjective.
I tested with swappiness set high and low, along with Mozilla FF, Thunderbird, xchat and mgt, I opened 3 2560×1920 images in the GIMP and performed a few operations on each. Neither setting affected performance much, except that with swappiness set high it may have been a little slower. That said, the GIMP maintains it’s own cache, and I have that set at 256MB.
I have swappyness set to 10 now. Not sure if that’s good or bad, or whatever.. *shrug*
I found a short review of Rekall via Linux Today this morning.
It has aspirations to be the MS Access of the Linux (and I suppose Free Software) world and while I’ve never used Access this little program looks impressive! The community supported RekallRevealed website has lots more, including screenshots and FAQs.
This handy tip from Kevin Lyda is useful. Someone else posted about the record function of Vi a long time ago but of course I forgot about it!
Saw this on slashdot so probably everyone else has too.. Anyway, this comparison of the Linux 2.4 and 2.6 kernels is interesting, if only to show that serving web pages under Linux 2.6 “more effectively used system resources and served 5 times more Web pages than the 2.4.18 kernel did.” Boss, can we upgrade now?
Yay! I’m in Linux 2.6 land again. I couldn’t use it on my last PC as it would freeze for some reason (the machine wouldn’t shut down properly either when using 2.4 so blame the h/w somewhere!) Anyway, this article apparently is all about how fast 2.6 is, I haven’t read it, but it’s an excuse to post this!
This project looks promising. It’s an attempt to make MythTV easier to install by supplying it with Knoppix. AFAICT you install the backend on your server and it’s even possible to run the frontend from the Knoppix CD on a different machine. Unfortunately the recommended hardware spec is well beyond any of the machines I own. That said, I’ve downloaded the ISO so I’ll certainly give it a go!
In a radio interview (realaudio link) this morning an “expert” told the nation that the DDOS attack on SCO was orchestrated by “people who are promoting a thing called open system software where by you can have competitors for the Microsoft products which are essentially free.” Peter Aherne provided a brief transcript of the interview and it looks shocking in it’s ignorance of the facts!
There’s a lengthy thread on the ILUG about it including links to articles debunking the interview.
The serious accusations in this interview need an answer and sooner rather than later!
Update! Nils posted a cleaned up transcript of the interview, and Gavin McCullagh posted one too.
Jesse Long is carrying out a survey to find out what browser Linux users use. If you use Linux please visit her site and complete the survey. It’s short, and she’ll be publishing the results soon so get your votes in quick!
A thought occurred to me, she could simply use the browser identification to find out what browser the user is using, and they’ll usually have the OS in there somewhere too.
Update! Jesse mailed me saying it was a short term survey so check the CLUG archives for the url if you want to do it!
