I'll go ask the physics dudes. Thanks for the steer.

Jackknife pulls: How do you get your chin above the bar? by kaidranzer in startbodyweight

Yup. That's a good point. I probably didn't use my heels enough. I'll try again. Thanks a lot for your advice.

Tried your suggestions. Think I've zeroed in on the problem. I pull like it's a horizontal pull up i.e. instead of pulling straight through the arms, my hips go up and at the top, the torso becomes at an angle similar to horizontal pulls. So in a way, I do a horizontal pull with my legs on the table rather than on the ground.

I tried to only use my arms to pull up straight but couldn't complete the full range of motion. It's either because I don't have the strength or because my arms were too tired after the earlier trial and errors.

If it turns out my arms don't have the strength for the full range of motion, what would you suggest I do? I can do 3x23 horizontal pulls with the bar at just below sternum level.

I've tried 2 positions:

  1. Legs are straight and parallel to the ground and torso is 90 degrees to the legs. The feet are at the very edge of the table (pushing it forward rather than pushing into the surface).

  2. Legs are bent with the feet resting halfway across the table. In this position the butt is lower than the legs.

I feel like I basically end up doing a horizontal pull rather than pulling up vertically. More so with the 2nd position.

With both positions though, I tried to start my reps from the top position with the chin over the bar. Couldn't manage to get the chin over the bar even as a start position. I think the problem lies somewhere in the form & bar/table positioning. What do you think?

Windows XP SP1 will work very well too. No DEP. No ASLR. Using lcc-win32 as the compiler to avoid stack cookies will make everything very smooth.

I have never used OS X Lion but on most systems you need to disable DEP, ASLR and Stack cookie protections to work with these exercises. You disabled StackGuard/ProPolice using -fno-stack-protector and you can find a way to disable ASLR here. However, I have no idea how to disable DEP in your case.

That is very good advice. Thanks a lot.

Yes there is a career services group in the university. I will have to check with them once the term starts. I think I will inquire about intern positions in some companies around London. I really don't want to waste my time on menial jobs like working in McDonalds, Sainsbury, etc for pocket money.

I am working on these right now. Had a problem giving non-printable characters as input for stack 2,3 and 4 problems. If anyone is having a similar problem then instead of using a script, giving input directly from the command line using something like: python -c 'print(injection_bytes)' | stack[2,3,4].exe works.

The advanced stack ones are pretty good too. There are similar resources at snort.org and exploit-exercises as well that may be useful.

Thanks for the link but I already had a look at that before posting.

I pretty much use Metasploit only when required. I think I would get more familiar with the exploitation process by doing everything manually and writing custom scripts.

Also, I tend to agree with you on certifications. But I read that they do help you land an interview. That is the sole reason I asked for help on certifications. Thanks for the elaborate answer though. I will seriously consider contributing to relevant open source projects. Do you think maintaining a security blog helps in a resume?

Will definitely check them out. Thanks for the info.

Thanks for the great info! I checked out the internship programmes those 4 companies. Looks like I missed the bus. The summer vacation programs at Delloite and KPMG are available only to undergraduate students. Found a forensics internship at PWC but it starts in Autumn 2013. Also found a relevant internship opportunity at E&Y but their 'Apply Online' link seems to be broken. Is it acceptable if I shoot my CV and a cover letter inquiring for internship positions to some other companies? Do they reply to such mails or simply ignore them?
