I'm surprised you aren't aware of OpenCourseWare ( http://ocw.mit.edu/ ). It's been around for several years now, and its existence could cause one to read your post as sardonic or tongue in cheek.

I wrote this post before reading the parent; I've moved it to be a reply to the parent because it's clearly related. I have some cognitive dissonance on this issue. I'm not sure what to conclude, so I'll just air it. On the one hand, I woul

May I suggest the #linux channel on irc.freenode.net for questions like this?

It's been done on sensor motes too. http://planete.inrialpes.fr/~francill/Papers/Code_Injection_... It's not surprising that it's practical; it's basically just a souped up ret2libc attack.

I am a die-hard Linux fan. However, I recently discovered that the latest Powerpoint is head and shoulders above Beamer and OpenOffice (try SmartArt, for example), so I use the school's Windows machines just to work on my presentation.

Oh, of course. I errantly assumed they didn't have root at the same time as you still had access.

C-C-C-COMBO BREAKER! Seriously, though. My account is nearly a year old, so I'll go ahead and say it: this is a Reddit thread . Stop. Now.

Fun fact: chatroulette exposes to other chatroulette users 1) your IP address 2) the fact that you're running this random-ass network-exposed Flash app. IP addresses are geolocatable, so it's not so anonymous. Would be cool to have a help

Right idea, but a better argument is "does an apartment half the size cost half as much?"

This argument gets trotted out in all sorts of internet discussions re: CS education, and it's bogus. You have to be able to stand on your own before you can contribute meaningfully to a group. More importantly, individualized assignments d

Oh, I thought you were insinuating that any truck roll cost $2000. In this case, I can say that your original statement is incorrect: it's not $2000 per customer, it's $2000 per residence at most. (Consider college towns, where lots of re

My friend lists correspond to privacy settings, not human-friendly groups (just photos, nothing, professional contacts). They should divorce friend lists from chat groups.

It means writing code, period. On your original note, "learn the LAMP stack" is, IMO, not especially ambitious for 5 years. Get a good CS degree (3-4 years) and actually try to learn the material instead of just passing, and learning the sp

I just TAed an introductory security class. The crypto project involved building a secure channel, and messages were authenticated with HMAC. We authenticated E(msg) || HMAC-SHA-256(msg) by computing HMAC-SHA-256(D(E(msg)) and bytewise comp

Still not a data-only enabler -- greets the user with a "what is the number of this phone" dialog on first use. Guess I shouldn't expect 100% free outgoing from Google; they probably don't stand to make money on that.

Because that doesn't work across classes. For introductory classes, a grade of A might correspond to a minimum of 90%-95% correct answers on evaluations because everyone excels at the material. For upper-level classees, a grade of A might c
