To users, $20 worth of food doesn't tell them anything about what they're actually going to buy when they arrive at the venue, whereas $1 for a $2 cup of coffee specifies exactly what they'll get. You might also only spend $18.50 of your $20 credit and can't find something worth ~$1.50 to buy, which can leave a bad aftertaste for some people.

Also, this allows merchants to prepare much more effectively by overstocking on the items being featured. Or they could discount an already overstocked item just to get rid of it.

All in all, people visit restaurants for specific (signature) dishes, not for the restaurants themselves, so it all fits together.

hydrazineon Ask HN: I just wasted 4 years of my life. Now what?

I agree with what iqster said. If you do decide to come to the Bay Area, definitely familiarize yourself with the state of tech here first (and network like hell!) and look for a job you love doing. Being a code monkey is only fun if the project is fun. Good luck and stay strong!

hydrazineon Ask HN: I just wasted 4 years of my life. Now what?

guynamedloren, with your passion and experience, I can see the following happening:

Day 1: Move to Bay Area, Day 2: Land job, Day 3: Chase dreams

Just show employers what you've done and what you want to do. They'll understand if it doesn't coincide with your degree, and frankly, I don't think they'll care about it.

hydrazineon Ask HN: Do you still use the same online handle?

Mine haven't changed over the years, but I have different handles for different types of accounts. i.e. professional, casual, gamer, hacker.

hydrazineon New Vehicle Engine 3.5x More Efficient Than Combustion Engine, -90% Emissions

I'm quite fond of Antoine de Saint-Exupery's quote, "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."

(And my mistake, didn't see doron's earlier post.)

hydrazineon Using prime numbers to make better backgrounds

Gonna try this with pseudo-random opacity styling for even more variations.

hydrazineon Ask HN: Does anyone actually code at a hackathon?

I was at a Zynga Hackathon at Berkeley a year ago. I suppose it's true a good amount of networking goes on, but that didn't bother me too much. I was really there just to hack something together overnight, and my team actually moved to a separate location so we wouldn't be disturbed. So overall it was a pretty good experience despite what other teams were doing. Hope you also feel this way in the future!

hydrazineon Random Startup Generator

StumbleUpon for startup ideas. Awesomely amusing!

hydrazineon The Size of the Human Radio-Broadcast Bubble in the Milky Way Galaxy

Sorry, I meant discover as in through our bubble's reaching them in the future (ensuring they're at least 100ly away).

hydrazineon Who else is hacking a project instead of watching the Super Bowl?

Pacman AI > Superbowl!

hydrazineon Japanese hacker earns $13,174 for reporting Google security holes

IMO Finding live vulnerabilities (with a passion!) outweighs most scripted interviews.

hydrazineon The Size of the Human Radio-Broadcast Bubble in the Milky Way Galaxy

All in the name of technology..

Assuming no ETs exist within our 200ly bubble, if ETs somehow discovered our signal and made contact, our level of knowledge would jump a few centuries at least.

hydrazineon Aerial footage of uncontacted Amazon tribe

True, though they may have filed it away as an unexplained phenomenon, given that the plane was tiny and the camera was shooting from a mile away.

hydrazineon I pitched YC, was rejected, just closed a multi-million dollar round.

@apoorvamehta Same here; "doubt me and I'll prove you wrong"

hydrazineon Google: Bing Is Cheating, Copying Our Search Results

In any case, if Bing is indeed copying Google's results, it is utterly unethical even if users are receiving accurate search results. As mentioned in the article, what Bing is doing is analogous to copying Google's "exam," which by any reasonable standard is wrong, even if a "proctor" didn't specifically state this rule.

Perhaps Google has patented a few of its search algorithm components.

hydrazineon Photography - 24 hour shot

This is breathtaking.. An automated tool would definitely be useful and welcomed, but half the challenge and reward is also staying the 30+ hours to capture the image.
