Hey, I got a sylvania netbook on my birthday and was wondering if anyone knew how to put linux on it and also if there's even a netbook distro of linux that's compatable with it. I've got to check out the system specs still, but when I do I'll post them up here. Thanks in advance.

Networking - just dont like it so dont really look into it. Server security - havent had the time to really look into it, been stuck on web security. Also, I seem to have problems with windows xD

If you want something like exploit dev and reverse engineering, check out damn vulnerable linux

Yeah, I realize, but likely it won't and if it does I could use advertisements, donations, etc. If it came down to it, I could just set up a server and get a good internet plan.

Yes, I'm thinking of starting one, but it'll more than likely be like a small amount of people. I just wanted to start one because on the last social networking site I was to work on, we got a lot of it done, and then a lot of the team working on it sort of dispatched. The project was just too unorganized. I know it's most likely not going to be popular or anything, but it's worth the shot that I'll get that "right place at the right time". I'm not looking to make a profit whatsoever, I already have other methods of making money, this is just because I hear a lot of people saying that facebook is so much better than myspace or the other way around, and it would be really cool if people agreed on liking a site that I helped build. @okiwan Lol, nice - I never thought that they'd actually make a movie about that. o.O <offtopic>And that's a good song on the trailer.</offtopic>

Agreed, project euler would be a great place to start - at least that's the first thing that came to mind, it's more math-related, but that's a big part in programming I guess. Edit: And a few extra puzzle ideas to solve would be: 1.) Sodoku solver 2.) Shortest-path finder 3.) Quadratic equation solver (really really simplistic - so idk if that's what you're looking for) 4.) Computer character recognition software (solve captchas) - a bit more challenging

I'm not sure if this question was already posted but I was wondering: What do you like about Facebook that's different on MySpace and vice-versa? What feature would you want them to have that neither of the sites have? Thanks for any input

Ahh, yeah, thanks for reminding me about the captcha, knew I forgot to do something. And there might actually be a few vulns at this point, it's still really under construction, I'm going to add eventually categories, a search bar, etc. as well - just wanted to have the general skeleton of it so I could get input earlier than after I completely finish and have to remake the whole thing lol.

@digip Good point, didn't think about that, and coincidentally, the javascript being used to do that was extreme overkill because the .html file was being parsed as PHP anyways. I did that mainly just so I could use AJAX. @VaKo Thanks for the links, I'll take a look at them.

I just finished writing most of my blog so I was wondering if anyone had any suggestions on what else to put into it. Any comments on the design like ideas about what the banner should look like, how the user navigates through the site, etc. I'd really appreciate any input negative or positive so here it is: http://jonnycake.webege.com/ .

Hey, yeah, there's so many different places to start out. Best way to learn though, is to set up a server and let the kids hack into it. Teach them the basics and let them get into it. That's how I started learning (other than hackits.de which RogueHart mentioned). Show them how things work and suddenly they'll be figuring things out for themselves. I know personally that reading a tutorial didn't help me as much as coding my own programs and learning the different (safer) coding techniques did. On a side note (and I realize this could be considered advertising, but I feel it would be relevant to the thread), me and a few of my buddies from hackits are starting up a new site, it's going to be a forum, tutorials, and before long a challenge site. I would love for you to check it out, and maybe when it gets bigger you'll be able to use it for getting information to share with the kids you're teaching: http://www.t3kstorm.com/forums/

Hello, to all of you in the community. Me as well as a couple other old hackits.de users are attempting to revive hackits since it disbanded in somewhere in 2008. I was hoping that we could get some users from here to build a bit more content as we still haven't gotten the database backups from the old administrators (who don't seem to be bringing it back up). We just started a forum and will probably make challenges in the, hopefully near, future. We need to build a user base back up and we'd love help with the community to do so by joining and helping the content of the current forum. More information here: http://hackits.zapto.org/forums/vbulletin/showthread.php?t=9 The site is just getting started so configuration changes will be going on in the next week or so so bare with us. Thanks, Jonnycake

You can use the linux command: md5sum. There's also a windows version of it.

So, I am working on a blind sql injection vulnerability so I went about it the normal way. Check if the first letter is greater than another letter to decide whether it's this letter and if not in what relationship is it, however > and < are filtered out to prevent XSS (which they are protected against and ironically not protected against an SQL injection, go figure!). So, here's my theory, if I were to subtract the int value of a letter from the int value of the first character in the string and then cancel it out by dividing by the absolute value of that result, it will allow me to find less than, equal to, or greater than by checking for -1, 0, and 1 respectively. But, I have a problem: I can't seem to convert the char to an int! I've been googling all day and yet haven't found how. Does anyone know how I could do it?

Well then, I'm shutting down my ssh server until the patch for the exploit is written! :) Edit: Although this could just be a prank to scare people o.O

Works fine now anyway, I just got the files off and did the regular recovery thingy and then put the files back on the computer after working for about 3 hours at 2:00 am. Insomnia ftw :D.

Thank you so much, I'm gonna try it tomorrow, I hope it works, if not I'll be back. Edit: BTW, I think it is just windows that got messed up because we recently had a virus and that's what I think messed up the file. When I get the files off I'm gonna try to figure out if the virus is what deleted/corrupted the file with some reverse engineering :D *dances around happily at his chance to experiment* :P

So, my parents computer recently....well decided it would become dead. Okay, so the error I get at startup is: So, obviously I figure I'll just throw in a linux live cd and start up and get the files off of them that we need backed up, but here is the problem - the cd drive is broken as well (which I didn't know until about an hour trying to figure out why the live cd wouldn't start). This means that I can't replace that file or get any files off of it since I have no access. I would use a flash drive but I have no idea how to get it to start up off of it. My question is: is there any way I can get the files off? Theory: Mount the internal hard drive as an external hard drive on a seperate computer and backup the important files - will this work? If not, how else could I get the files off if at all? Thanks in advance.

So, I've got a PHP shell that I'm working on with a friend of mine and just wanted to show you guys it and get some advice on what else to add. Here's a link to the download: http://jonstockton.is-a-geek.com/~jonathan...hell-0.3.tar.gz Thanks in advance for the input. :)

Lol, yeah, just an experiment (and I'm trying to impress my algebra teacher that used to be a software engineer :P).

@OneTimePad: Thanks for the link, I'll look at it a little bit later today. I think I'm probably just gonna make it able to run functions and have variables. Of course, writing it so that it can do while and for loops would be fun too *thinks*. Would take lots of code, but would be totally worth it lol. @Gyf: Well, it would be fun :P

Hey, thanks for replying. That's sort of what I wanted, but not exactly. I know about function pointers and stuff like that. My problem is that I want to not have to explicitly define names. For example, I want to be able to run a program which accepts input which will be run like it would be if it were in a compiled program. Like, an input of printf("Hi\n"); should print Hi to the screen. I've been trying to look into the ELF file structure and getting the memory address from there, atm, this is my eval function: // Call the function located at funaddr using the arguments in argv[] int eval(int* funaddr,int argc,char* argv[]) { int x; // Set up the stack to run the function for(x=argc-1;x&gt;=0;x--) asm( "pushl %0\n" : : "r" (argv[x]) ); // Call the function asm( "call *%0\n" : : "r" (funaddr) ); // %eax has not been reset so it will return the return value of the function called return; } My problem is getting the function address so that I can run it (which I assume I can do since gdb does). Anyway, hope I made what I wanted a little clearer. Edit: BTW, example of the use of the function: eval((int*) &printf,1,"Hi\n");.

My favorite language is Python for a variety of reasons (one of which is it was my first actual language). It's really simple and quick to write, you don't have to worry about the type of variable it is, the library is pretty big and a really good library, there's a lot of really pretty good tutorials, and it's almost pseudo-code abstraction level. That being said, I agree completely with dr0p. For pen-testing, etc. you're going to need lower level languages to find vulnerabilities in applications so C and ASM are essentially requirements. They're also really fun and interesting to use. As for what I use the languages for:

Xor does it bit by bit with the binary. xor 001 with 001: 001 ^001 ------ 000 You xor bit by bit. The xor of an integer as: binary[8]={0,0,0,0,0,0,0,1}; binary2[8]={0,0,0,0,0,0,0,1}; int x; for(x=0;x&lt;8;x++) binary[x]^binary2[x]; That's doing xor 1^1.

Yeah, really. Did you figure it out yet? I'm starting to wonder about it too! lol Edit: Ooooooooh, found it!!!! http://blog.arahul.in/2008/06/find-duplicate-element.html Edit2: But that only finds one non-duplicate element. That's what's wrong with it lol. Edit3: Also, if I'm thinking correctly, if there's a number that shows up an odd number of times, it won't get canceled out and end up being output as the non-duplicate element and if there's no non-duplicate elements, it will output 0 which in most cases is not desirable.
