Before this lovely state, I had to wait while it ran "windows gets ready to run for the first time" for about 20 minutes.

wait.. it just rebooted, looks like it is done.

So in total, it took me 5 minutes to unpackage the VAIO plug it in and turn it on, and about 28 minutes to run Vista for the first time.

Two things I don't understand:

1) This is a brand new US$2,000 laptop with a fancy hybrid hard drive, why does it need to "check my hardware"?
2) Why OEM's put up with this? I mean Sony should have enough leverage to force Microsoft to provide them with a "quick firstboot" version of Vista.

Don't get me wrong, I'm not a Windows hater, I'm fine with it for the most part, but this just pushes my patience to a whole new level... has no one at Microsoft used a Mac and seen their elegant "firstboot" system? Or used pretty much any recent Linux distro for that matter?

btw.. windows is still booting...

I'm not quite sure why professor Dawkins would even consider something like this but it is hella funny.
Even if you are a big Pastor Ted fan, this video should still serve to show you the crumbling grounds that one must take to argue about logic and reason against an evolutionary biologist.

Yeah that's right, BASH.

Here's the scenario, let's say you have to perform a task that might take a long time (let's pretend you need to check the health of an nfs server prior to attempting to mount exports from it) but you do not want to block the main "process" waiting for it, here's how something like that can be implemented:

###################################################
# ASYNC NFS CHECK
# Rafael Ferreira <raf@ophion.org>
###################################################

# CONFIG FLAG - whether NFS has been checked or not
NFS_OK=1

# Runs a command asynchronously
# $1 is the command to run
# $2 is the callback function
async_run() {
        {
                $1 &>/dev/null

                # calling the callback passing the result
                $2 $?
        }&
}

nfs_callback() {
        if [ $1 == "0" ]
        then
                touch /tmp/$$
        fi
}

for i in $(mount -l  -t nfs | grep nfs2 | awk -F ":" '{print $1}')
do
        if [ $NFS_OK == "1" ]
        then
             async_run "/usr/sbin/rpcinfo -p $i" nfs_callback
             disown

        fi
done

sleep 1s

if [ -f /tmp/$$ ]
then
        echo "NFS OK"

else
        echo "NFS NOT OK"
fi
 

In a nutshell, async_run() is where all the action happens. It takes a string parameter of a command to be run and a callback function to be dispatched once the command is done. On the example above, I decided to block the main process and wait for the async call to return for at most 1 sec, this allows me to have constant execution O(1), no matter how long the async task takes.

Yeah, I know this is pretty silly, but hey, I like it.

My fav quote from that whole thread:

"I've never written a program before so I also need some help. Also I need a place to put it on the web"

We are indeed doomed....

http://firstread.msnbc.msn.com/archive/2008/01/15/579265.aspx

Now, to be clear, I'm not putting Howard Dean's deranged scream in equal footing with Mr. Huckabee's comments but I do see a parallel that could lead to the same kind of political turmoil.

Fundamentally, I see two things wrong with Huckabee's stance:

a) He manages to display complete lack of respect towards the US Constitution and the principles in which it was based b) He shows a lack of insight into the complexity of Christianity and how one must quantify what "God's standards" mean in light of the different interpretations of the Bible (I must say this one is extra troublesome coming from a "minister")

Well, enough said. Let's all seat back and watch.
