"In 200.000 years on Earth, humanity has upset the balance of the planet, estabilished by nearly four billion years of evolution. The price to pay is high, but it's too late to be a pessimist: humanity has barely ten years to reverse the trend, become aware of the full extent of its spoliation of the Earth's riches and change its patterns of consumption.

By bringing us unique footage from over fifty countries, all seen from the air, by sharing with us his wonder and his concern, with this film Yann Arthus-Bertrand lays a foundation stone for the edifice that, together, we must rebuild."

The movie features beautiful cinematography. If for no other reason, then watch it just because it's a masterpiece in showing off the beauties of Earth. Smile

Cool commandline completion in Ubuntu 10.04 with the default bash shell

Fri, 2013.05.10 - 09:41 — müzso
I'm setting up my company's new servers (installing Ubuntu 12.04, the current LTS release) and since a lot of configuration/features have to be "mirrored" from our old servers, I've set up SSH public key authentication so I can simply copy stuff with scp (and without entering the password each time) from the old server(s) to the new one(s). And I just got amazed by this: entered the start of the command specifying the server like this:
scp oldserver.ourcompany.hu:/mnt/
then I hit (accidentally) tab ... and voala! The builtin (out-of-the-box) command completion listed all the contents of the /mnt directory on the other server! Brilliant. That's what I call user (or admin Smile ) experience.

How to disable services in Ubuntu (using Upstart)

Ubuntu has been transitioning to Upstart for a long time now. In the early days one could disable a service only by renaming the job config file in /etc/init (to something that does not end in .conf) or modify the file so it won't start the job automatically.

How to install syslog-ng on Ubuntu solving the conflict with ubuntu-minimal

https://launchpad.net/ubuntu/+source/syslog-ng/+bug/42555
One of the problems with Ubuntu is its stubbornness. This bug is 7 years old now. It's pretty obvious that it's a bug and no Canonical employee ever disputed this in the bug's comments. The only progress they made so far was to replace the dependency of sysklogd with rsyslog (which was only to make Ubuntu's dependency system work since sysklogd was dropped/replaced with rsyslog over the years). It's a shame that Ubuntu doesn't provide more attention to the details. Sad

"Mac has many enhancements to Unix in the area of files. Ignoring the whole resource fork thing which is not used much anymore, there are:
  • the standard Unix permissions ugo rwx and so on. Normal Unix tools apply.
  • ACLs, viewable with ls -le and changeable with chmod [ -a | +a | =a ].
  • file flags viewable with ls -lO and changeable with chflags.
  • extended attributes, viewable with ls -l@ (attribute keys only) and changeable with xattr. (Note that there is no man page for xattr, but it's a simple program described with xattr -h.)

How to limit the number of records put into an INSERT statement by mysqldump

http://stackoverflow.com/questions/1293529/how-to-deal-with-enormous-line-length...
The mysqldump manpage says:

net_buffer_length
The initial size of the buffer for client/server communication. When creating multiple-row INSERT statements (as with the --extended-insert or --opt option), mysqldump creates rows up to net_buffer_length length. If you increase this variable, you should also ensure that the net_buffer_length variable in the MySQL server is at least this large.

"Did you know that you can play Tetris on your Mac? Of course you did, you can play lots of games. But did you know that there’s already a Tetris game built in? In fact, if you know your way around Emacs, you can play a whole bunch of awesome retro games like pong and snake."

Actually macosxhints.com had an article about this years before "the media" picked up on the topic. Smile But obviously this has been around even longer. Wink
