This is valid criticism, and I agree. The regular expression example is not made easier by his use of non-standard regex syntax. I have not read Dr. Harper's book cover to cover; I treat it as a reference. For that, it is quite useful.

I loved 150 when I took it, and program in SML from time to time to this day. Bob Harper (a CMU professor with a focus on PL theory) also has a really good SML reference that is closer to a textbook than lecture notes. http://www

I stumbled on this page after reading Matt Blaze's legendary paper about deducing master keys from physically strong, but cryptographically weak, physical systems. The paper is really good, and worth a read, even though it is from 2003

In the "Save as..." pop-up, you can set the file type to "Optimized SVG" (among other SVG output types, if I remember correctly). Picking optimized SVG pops up another dialog on save that can be used to configure the opt

Actually, the LaTeX template took the least amount of work of anything! It's a very slightly modified version of the default Pandoc standalone LaTeX template. You can recover the original (or something like it, depending on your versio

I'm the author! As some have guessed, I did, indeed, conceive of this for procrastinating and reading non-work materials at work. I don't actually expect to use it, but it was one of those ideas that I couldn't get out of my

So far, I've used two good strategies: - Spray PC into as many registers as possible, try to add those registers together as many times as possible, and store the sum at zero (or wherever the score ends up) - Load an assembled instruct

Uses the Gamepad API. I found it very easy to work with, in large part thanks to the corresponding MDN docs. The only weird part about the Gamepad API is that you have to poll it rather than handling events the way you normally would for ot

R12 contains the address of your score. In this case, that is address 0 - the start of the data segment. The score register is yellow, and the corresponding memory region it points to (the actual bytes of your score) are also yellow.

It also works with USB gamepads! At DEF CON where we will have this set up in-person tomorrow, we will have people playing on a USB Dance Dance Revolution floor pad.

I like the idea of sandbox mode! I'm definitely much quicker at reading ARM assembly after playing a few hours of this game over the course of making it.

Thanks for the kind words! This comment helped me realize that I had misunderstood the parent commenter's question. I have just pushed an update so that the up/down arrow keys only show up in the instructions if the max gadget siz

Oh, my bad, I misread your question. See a reply to your original comment: it changes the order for gadgets larger than one instruction. The default is one, but originally it was three, so the instructions stuck. I will make those confusing

Yeah, I may have sacrificed clarity for concision in this case. To answer by way of example, if you are given "add R1, R2, R3" rotating to the right will result in "add R2, R3, R4". As another example, rotating "mov

Hey, any specific questions? I'd be happy to explain anything that needs clarification. More broadly, any thoughts on how to make the game clearer? I know that a manual describing the instructions would help. But other ideas are welcom

A similar type of timing attack can be used to port scan your local machine (and other devices on your local network) from your browser. https://github.com/Flu1dTeam/PortScanner A while ago, eBay got caught doing this.
