The movie has everything good about the book and adds so much more. The book is too irrational for my taste. I had seen the movie before, but nevertheless it was good to remember this master piece.
From the everyday companions below, I must admit that Google and Wikipedia are my essential tools. There is not a single day I don’t visit them.
Google stores my email, calendar, rss feeds, some of my documents, and I’m waiting patiently for my Wave invitation. As for Wikipedia, it is simply the best knowledge database out there. I can’t believe I was an Encarta fan… it was so limited. You can’t imagine how many discussions have been settled over a Wikipedia page.
They are only a couple of year old, but I can’t imagine my life without them.
I also use other services, but all that Web 2.0 concept is not for me. If you need to “connect” with me just use the “good ol’ e-mail”.
One of the best TV series I have ever seen… Even though the end was fabulous, I must say that it is sad to think that it had to end. It was brilliant, simply brilliant…
Ok, I don’t look as sexy, but it sure feels nice to have some free time to finish the book I was reading and catch-up with the latest episodes of my favorite TV series.
But, right now… I’ll take a nap! Only when on vacations.
This must be based on myself… Lev Ylmaz doesn’t know me, but he certainly did a great job depicting me, specially when I’m on vacations! By the way, I’m on vacations.
And there’s a lot of other funny videos. These are my other favorites: [1], [2] and [3].
One of my C/C++ applications needed to provide information about CPU usage for debug and monitoring purposes. I never had to do anything like this, but quickly found what something interesting. The getloadavg is a standard library function that provides simplified information on CPU load average.
Because the function seems to point to /proc as source of information, I got to “take a look under the hood” and search for more information about /proc. I already knew that this so called filesystem (which in fact is only virtual) provides an easily accessible interface to kernel information.
Inside, it contains a folder called pid for each process running in the machine and several other folders/files that contain information on available memory, devices (e.g. disks) or kernel version.
If you take the usual look at the man page for proc, I’m sure you’ll find it interesting. it contains much more information than the one I was expecting.
To empty an existing file, without having to recreate it, one can simply
> file
There are other ways to do the same, but none of the them are as simple. One can
cat /dev/null > file
echo -n > file
If the goal is only to change the file access timestamp, them you can simply
touch file
Yesterday, I was talking about heroes with some colleagues… how many can you name from the picture below?
There is nothing that provides more help to a Linux SW developer than the manual pages. Here’s how to install them in a Debian based system (i.e. my desktop ubuntu system):
