When I used to be an "IT guy", everything had to be in Excel. I begged to switch to Access. Hell, I even built a few prototypes in Access in my free time to demonstrate how much better it would be (I was still a student). My point: Over t

The underlying issue is that broadcasters are creating an artificial scarcity to drive demand. I find that to be more unethical than exploiting a loophole.

Off topic, but the Reddit post about Neox Screen using the ShareX source code and asking for donations is quite disheartening. Not that anything illegal occurred, just the level of deceitfulness. http://www.reddit.com/r/opensource/comments

I got a chance to use one of these last week and was very impressed. It was incredibly responsive and precise. It had its clunky moments like any similar device, but I think the video on the homepage is a pretty accurate representation. A

You will always have bad people. The more people that exploit the system, the faster the system will change to be more 'fair', otherwise you're just handicapping yourself. Look at all the patent lawsuits. As they said in my business ethi

I can say from experience that a blank website is very effective in getting a stubborn client to pay. Defacing them is probably taking it too far though, and I don't see how it could be more effective.

I've built a few prototype multiplayer games that use web sockets (Socket.io actually) and the performance has been encouraging. One game I posted on HN had over 30 concurrent users without noticeable lag. It was also terribly inefficient

This seems like an image that could easily be created with the Pen Tool in Photoshop. Which, if I understand correctly, is a sequence of Bezier curves[1]. [1] http://en.wikipedia.org/wiki/B%C3%A9zier_curve

I'm sure lots of people have had unwanted encounters with Google's crawlers, but here's mine: I used to have a subdomain pointing to my home IP which was protected using Apache htpasswd. I naively had all of my clients' credentials stored

I think if we achieve the ability to be self-sufficient in space it's our responsibility to try to reduce our resource consumption on earth and preserve it, just as much as we preserve any part of our history. However, as we are currently d
