Yeah. OpenBSD compiles everything as PIC, has ASLR, they were considering randomizing the locations of objects within libraries and executables (I think this was or is being implemented), as well as limited what you can do with a ROP expl

Yep! That's the idea here: it makes it less likely to accidentally treat data as instructions. If you can figure out some bug in a JIT compiler to get it to write your payload to a page that will get turned executable, then you still h

There are a lot of prominent counterexamples though: - Blender (Blender's UI is pretty odd and entirely un-platform-like, but very efficient) - Photoshop (case in point, Ctrl-Z; I'm very glad Adobe didn't follow conventions

Personally, I don't think I would be very comfortable knowing I was hired because company X has to meet diversity quotas and not solely because I was the best candidate for the job. I think it's an offense to hackers in general—I&

You actually can, via (ab)using requestAnimationFrame. It's been a while since I did front-end development, but back in the day (...okay, 2014 ish) we'd batch DOM reads and writes, run through them the next time the frame was pain

I kid you not, it's taught in American elementary schools (at least it was to me, in the early-mid 2000s). ...Yeah. Thankfully my middle school general science textbook mentioned this shit's been known forever and the Greeks even

My guess: Since anysz mentioned he has 0 friends, there will be no social graph recommendations. Thus less-confident recommendations will show up, including spending some minutes in the same location as someone. It could then consider other

Taken from Pascal and other Wirthian languages. Nim actually looks vaguely Wirthish in some areas. Interesting.

On top of that, in a step function you really want to see what's being modified (that's kinda the point...). I suspect that monstrosity is easier to maintain than having state updates scattered around and having to jump to defin

Microsoft's net income increased dramatically under Ballmer¹ however. Dude made money. Apple's stock has stagnated lately, though that may very well be temporary. I think people discredit how smart Ballmer actually was, given how

Allow users to tag a set of hashtags as a category. Make hashtags user-taggable and suddenly sorting and categorizing is easy. Undoubtedly this just sounds like a good idea to the "few orthogonal abstractions" hacker brain, but wi

I took zentiggr's comment to be sarcastic with a hint of truth. I don't think his choice to use "sheeple"¹ or bring up Orwell detracts from his point. ¹ And let's be realistic, anyone who thinks the TSA actually imp

Try APL/K/Q/J sometime. Anything can be done in one line. (Note: does not mean should be done in one line....) There is something rather magical about solving almost any problem in a single line of code.

You can read about the awesome theory behind relational algebra. Gave me a great appreciation for how awesome SQL databases actually are (and why they work the way they do).

Watson's basically a "bring-your-own-knowledge-base" NLP platform. There's the developer site[1] if you can manage to read through IBM's marketing speak[2]. The docs are pretty good. -- 1. http://www.ibm.

About as much as you can buy Amazon Echo or Google Home actually. At least IBM makes very clear what the usage conditions of Watson are, and it's fully extensible.

You jest, but sometimes that's exactly what you need for short-lived programs¹. Bump alloc and free on exit is super fast if your space complexity is bounded. ¹ http://www.drdobbs.com/cpp/increasing-compiler-speed-

std::unique_ptr, move constructors, etc and you're pretty safe, but it's still not in the same league as Rust. In my opinion you should probably learn Rust unless you want to get a job writing C++ (e.g. game development).

While conventional voting is far from great, the first time someone hacks an online vote is going to set it back for decades. It could be better now, but it almost has to be perfect to get people to switch.
