There is a new page in the about section titled “My Gear” with a list of my computer setup at home complete with pictures. So check it out, and, let me know in the comments what you’ve got. Send me a link. If i get several good ones i may post them.

Have you ever needed to get into a mac but didn’t know the password. Maybe you forgot it. Maybe your roommate changed it and headed off for christmas break. Maybe you stole it in an airport and now want to use it. Whatever the situation, you need in but don’t have the credentials. I’m here to help.

In Mac OS X there are at least two methods for resetting a password. And it does require resetting. This isn’t windows, you can’t just boot off a cd and automatically crack the password. Apple decided to used modern encryption techniques 10 years ago that were probably 10 years old then to protect your passwords. Microsoft still hasn’t.

Method number 1: Follow the instructions here to boot off a disc and reset your password the apple way.

Method number 2: Follow my instructions below and reset it the “cool” way.

As anyone who follows me on twitter knows, I have added drop down menu’s to this site. Its nice, check it out, hover over the “About Me” link up there. Yeah, not bad. Also known by twitter users is the fact that i did not come up with the css, etc. that goes into this. All credit, copyright, whatever goes to @bradkovach (bradkovach.com). I have access to the themes he made for the lcsd2.org sites and i just copied and pasted from there without permission. So i’d like to thank him for his generous lack of anger/suing me.

Now the reason i wanted drop down menu’s in the first place is for semantic organization. Hover over about me and you get contact info, etc., stuff that belongs under about. It also allows me to have more static content while still using this theme. I rather like this theme/don’t feel like looking for another and would prefer to keep it. Now i can.

Sometime in the future i will be adding things like contact info and actual content. If you have any suggestions/hate, please use the contact page to let me know.

Earlier today, i was sitting down, watching tv with my brother. We were both on laptops doing other things at the same time. He started watching an episode of loaded featuring 50 cent. I do not like 50 cent. After several minutes of the god-awful, talentless, garbage, i got sick of it. Did I go the pansy route and ask him to change it? No! I took the high road and made a few changed to my dns server causing all sites he tried to go to, to instead, go to kittenwar.com. I’ll show you how i did it.

As very few of you know, (maybe i should actually put something in the about me section) i started this little website as a project to learn linux better and to learn to manage a webserver. Since then, this little project has turned into something i actually care about and take a measure of pride in. This is due in no small part to the miracle that is google apps for your domain.

I like managing a webserver. I like manually managing bind and apache from the command line. I like the sense of control i feel when i am able to make any changes i want any time i want. What i don’t like though, is email. Email is evil. Go ahead, take a look at the configuration files for sendmail sometime. Try postfix, not much better. I don’t want to do email but i want to get email. So what did i do? I went with google apps for your domain.

I’ve been using host-tracker for a while now to monitor my uptime. Today they sent me my quarterly report and i’m pleased to report, to you, that my uptime is better than many for pay shared hosting providers. My little server that i put together myself, running directly on the grid with no UPS, running off a little tiny slow home dsl connection, and connected to that connection via an old wireless bridge is better than some datacenters. That is just awesome. Below i have included the report they sent me, whitespace and all.

*Update*So, wordpress helpfully stripped the white space. Yay!

So finally, 3 weeks after the scheduled date, wordpress version 2.5 has been released. Wordpress is the software i use to power this site and the new version gives me some nice new featured to help with that. That doesn’t mean you will see any better content nor will it come any more often. It just means that the new version is out and i’m using it.

I’ve made a new page detailing the site policy, etc. I also realized that you apparently cannot leave comments for a page and that no one could contact me without using a post that may or may not be relevant. I’ve created a new text box on the left sidebar(to the right) with all my contact info to get ahold of me. I also turned on user registrations so people can have a little more of a permanent presence on my blog. If this starts getting abused by bots, etc. i may have to get some capchas in there or turn it off. If you request, i may up your status from subscriber to something that can submit posts, etc. to me.

I hope you enjoy the new changes and happy blogging :).

So, as you know from previous posts, I’m a geek. That means i like to do geeky things and then tell people. What do i have this time you ask? Why its a list of prime number up to and including 1005833, not counting 1(it was slightly more effort than i wanted to put in to this). Yeah, so i got bored and wrote the little program below in java to generate this. I decided to run it on my file/web server here. Its a 2.6 ghz pentium 4 with hyperthreading and it took about 4.5 hours to generate these.

public class CountPrime
{
public static void main(String[] args)
{
for(long i=1;i<30000000;i=i+2)
{
for(long j=i-1;j>1;j--)
{
if(i%j==0) break;
if(j==2) System.out.println(i);
}
}	}
}

This bring me to a little mini-rant. Notice how i’m using longs in the code above? Why not just do something smart and use unsigned integers giving you a nice 2^32 long space to work with? Well here’s the answer. JAVA DOESN’T FREAKING SUPPORT UNSIGNED ANYTHING!!!! I took 2 classes on java and never heard a word about this. I’ve defended java from idiots that for some reason like c or c++ without knowing this. How do you freaking design a programming language without support for something so unbelievable basic as unsigned integers or short or chars or bytes or longs or anything like that?

Ok, that was a little more than a mini-rant but i feel better now. Anywho, here are the list of prime numbers. The file is tar’ed and gzip’ed so if you’re using the only os in the world that doesn’t support it built-in (windows), its time to upgrade to something ‘nix based.
