not your average end user

I’m probably going to need a dance game sub-blog at this rate.

(I wrote this post for our underclassmen, because I kept needing to explain how to get to graph mode in r2 and didn’t want to keep repeating myself).

PEDA may be useful It’s a script that makes gdb easier to use (run these in your shell) git clone https://github.com/longld/peda.git ~/peda echo "source ~/peda/peda.py" >> ~/.gdbinit echo "DONE!

Mostly just trying to write down primitives that I figure out so I can reference them later / share them with others.

buffer_overflow_3 Binary with a handrolled, static canary.

Learned: Lua metatables (i.e. operator overloads) Deleting frames from gifs in preview breaks them Sora’s and Dan’s Stepmania docs are really nice Oscar came up with a nice DDRIllini logo.

I constantly find myself going back through old exploits for scripts, so I’m going to try keeping up my “current favorite pwn scripts” here. from pwn import * # change logging level. options: debug, critical (high, low) context.log_level = 'critical' p =

via Sometimes you want to pipe things into a process’s stdin (to emulate typing things, for example.) echo "blah" | binary python -c "print hello" | binary # is another common thing.

Learned: stripped binaries don’t point to main binja can find it anyway the dynamic linker runs before any of your program code trying break _start in gdb will probably hit the linker’s instead I was working on TokyoWesterns 2018 load and this came up (st…

Partial RELRO means you can do GOT overwrites.

Not a complete writeup, just my thoughts while working on it.

I started a ctf blog at ctf-blog.

Last month, we ran the 10th iteration of Rumble in the Prairie, DDRIllini’s yearly tournament.

We implemented Stepmania (Dance Dance Revolution) on an Altera DE2-115 during the Fall 2017 semester of ECE385.

Last semester, I took an “Introduction to Computational Linguistics” class.

It’s halfway through a busy year!

During my second semester of college, some friends and I decided to build custom split mechanical keyboards.

tl;dr download openitg compiled for 64bit debian/ubuntu/archlinux here. should work with the right versions of packages installed and libraries symlinked, which it’ll probably complain about when you try running it.

During one of my classes last semester, my professor stopped me and told me to go look up an article in the New York Times.

I went to Boilermake IV (Purdue’s yearly hackathon) with some friends.

Octopress 3.0’s docs don’t have one, so here’s a Github Pages quickstart.

A quick and dirty script to hook together Twilio (SMS) and Discord APIs, for a friend who can’t otherwise connect to Discord.

Just a quick post to keep me sane during the leadup to finals :^)

Instead of getting a full night’s sleep before a week of classes, I wrote a python script that sends cat facts to a list of friends logged in to our university’s server.

The gobby download page somewhat unhelpfully states that “Gobby runs on Mac OS X, however we cannot offer a pre-built package at the moment.”

I couldn’t find a satisfactorily quick answer for this with a google search, so here it is plain.

After last Christmas, I decided to buy myself a Pebble.

A friend of mine loves to sing.

I recently set up a Terraria server to play on with new friends from school.

Ever wanted to hear floppy drives sing?

I led a group of students to a tour at Google’s Chicago office after school one day.

To wrap up an old loose end with a friend, I finished building an NES-themed media center PC built around a Raspberry Pi.

Perhaps a few years late, but I just found this positively gorgeous final lecture by Randy Pausch.

One of my school’s yearly events is a bridge competition put on by the science department and sponsored by a relatively successful construction company full of alumni.

Two weeks ago, I finished my Eagle Project.

Looking at Google IO’s website (mostly with info for last year, so this is admittedly dated) I noticed an easter egg of sorts, a pretty Javascript application mysteriously titled "/experiment".

About two weeks before Valentine’s Day, I got the idea of making a Zelda-themed card for a friend of mine.

Recently, a Meatheads burger joint opened up just down the street from my house.
