This is documented as a Hacker Space Design Pattern. http://hackerspaces.org/wiki/The_Tuesday_Pattern

Problem

Every weekday sucks. You will not ﬁnd any day when every hacker can attend a meeting. Someone always has an appointment.

Implementation

Meet on Tuesday. Since all days are equally bad, just pick the Tuesday. End of discussion.
In that case, I think what's interesting about the Dvorak market failure (or non-failure) is that it doesn't require asymmetric information or irrational consumers.
May want to change the name. GroupTabs sounds like everyone is paying together (are they?).

If we are just unlocking deals by having enough people show up - its certainly a chicken or egg problem determining if the people go. What happens if not enough people show up? They get screwed out of the deal that they went to a specific place solely for. The appeal for business owners is to get people to come, right? This means that the ones you are attracting are by virtue not customers otherwise. This is tricky and may require pre-organization from the users to make sure enough people show up to unlock the deal.

Adobe After effects is a good example of a fairly standard app that will happily chew through 8-12 gigs of ram when working on moderately complicated videos.

I also know people who work with fluid dynamics and the new workstations they bought for work have 48 gigs of RAM.
Absolutely! I've thought about this so many times... what is 5 seconds for you (allowing someone to merge in front of you) would translate to much much faster commute to _everyone_ else. It is all about the balance between my personal greed and what's better for the common good (if only we could solve this on _and_ off the road).

Where I live there is terrible traffic... and I've contemplated causes and solutions many a mind-numbing commute. I realized we behave differently when we are behind the wheel... Very few people would behave or maneuver the same if it where lines of people instead of cars. That is why your best chance to merge is to make eye contact with the other driver - if they recognize you as another human not just another vehicle than they are much more likely to move over or make space.

When I drive (during rush hour) I suffer a lot to justify my actions. What I have settled on... is a simple rule: In any situation the person who is in the wrong is the one who has contributed to the impediment of the overall flow of traffic. This comes back to what zepolen says (and I agree with). If we could ever make the connection that what's good for my fellow (wo)man is good for me too... we would be so much better off in general.
So, what would happen on major interstates if highway patrols kept a steady pace? Is that a viable solution? Wouldn't they eventually run up on another wave of cars and ruin everything?

I would be really interesting to see if this actually improved interstate bandwidth during rush hours. But even more interesting, I bet a good portion of drivers would get upset at the fact that there are huge, unused gaps. I wouldn't be surprised to hear from people who think it is grossly more inefficient than regular old traffic jams...
They're a non-profit before they are Something Awful forum members. Not trying to disrespect goons here, I'm one also, but the priorities need to be straightened.

See RiderOfGiraffe's comment on this same page.

"potential competitors: are there any (if none, perfect!)." ... or it could indicate that there is simply no market for this idea. Seeing a few competitors at least validates the idea & proves that at least some other companies think there is a market for this.
Yes, many people will pass you and go in front. That's not such a big deal since many of them switch into yet another lane (Some will even exit the freeway only to immediately re-enter) as they try to gain even half a car-length on everyone else.

I don't feel like competing with them.

Personally, I'm not trying to fix traffic for everyone. I'm selfishly trying to make my own commute as pleasant as possible. By following the advice in this old article I've managed to greatly improve my own drive, and I find the amount of time I spend in the slow pockets of traffic greatly reduced.
I think you misunderstand the point I am making. Which is that if it is in demand, then all else will follow. As it hasn't, then it's probably not.

Your comment, "Someone suggested the Pomodoro-technique on HN and I quickly threw together this page that is supposed to help me try Pomodoro out today..." is marked as [dead].

Seems strange to me too - it's the only [dead] comment of yours.

Think of it as an up-front cost that you expend before doing any actual work. So BM is slower in some cases, and faster in others. In most short cases the cost of setting up outweighs the advantages of the more complex algorithm and then you're better off to brute-force it.

The Moby-Dick example, however is not such a case.

Just like it takes longer to prepare an offset press to make a single copy of a page compared to just slapping it in to the photo-copier. But if you need a million copies, you can't beat (rotary) offset.

edit: I've re-constructed the original comment this replied to because I'm not happy about the recent trend in comment deletions (see below), that's the fourth time in a few days that I come across this. To the author of the parent of this comment (you know who you are), why did you delete your comment after receiving 3 serious replies?
I agree that this doesn't work well around Boston. My opinion is that the fluidity of traffic, ie. lane changing, doesn't break down at low speeds in Boston. If you let a cars length open in front of you it will fill up with a car. I tend to think that this makes efficient use of the pavement available and tends for a traffic flow that is as maximal as possible but I don't have any evidence about that.

Thanks for the feedback. The service is actually free to users, so know paying together. For example, tomorrow night's deal: You get a free glass of wine, sangria Or beer with every tapas you purchase at a restaurant, Sala, on the Bowery in NYC.

Whether a deal tips or not is our biggest issue...which is why we are setting low thresholds. To address it, one of the first changes we've made is posting our deals earlier than we initially planned to...instead of that morning, we are looking at anywhere from 1 to 3 days ahead. Also rolling out an update homepage with a feed of upcoming deals to build up interest.
I used to do this every once in a while. One thing to be aware of, are large trucks behind you at the top of hills. They tend to want to increase speed going down hills to use their velocity to climb the next. It's probably a good idea to accommodate this.
I admit that your point was very well hidden.

It probably helps that I am rich while (as one might expect) most HN users are not.
Well yeah, dudes -> early adopters. However, I would love to hear your opinion about the concept. Would something like this have a chance of catching on?
why exactly do you need to switch gears? Just leave it in first. And engage the clutch when you are stopped.
Things like this make me wonder why anyone would want to write a huge project (like Firefox) in C/C++. I can understand wanting to re-use some legacy code, or perhaps the need for a few bits of optimized, low-level code where you really need the performance...but why not write the majority of the code in something like OCaml? I know there aren't as many good OCaml (for example) developers out there, but I'd bet that the end result would be just as fast (or faster) than the C/C++ version and have way fewer bugs (thanks to the strong type inference and succinctness of the code).
I can't speak for PyPy, but Rubinius isn't a project of ruby-core... and MRI is written in all C. And MRI isn't the latest version of Ruby, YARV is. (MRI -> 1.8, YARV -> 1.9)

Finally, Rubinius is architected totally differently than YARV. Rubinius uses a JIT, YARV is just an interpreter.
This is obviously a mistake on Apple's part.
Green waves are a pet peeve of mine. They've tried to implement these where I lieve... a spectacular failure. Green waves only work when there is NO traffic. Speed is regulated and the flow moves fine. During rush hour they are a disaster. Every light is backed up to previous. My light turns green, then I have to wait 10 seconds for the next light to turn green and the entire line of traffic to move, before I can advance. This usually results in a stop at each light. A much better solution is what I remember from NYC: all the lights turn green at once, all the traffic moves.
I switched to Dvorak about ten years ago. My experiences don't line up with a lot of the speculation I see in this thread.

* Most speed gains come from hunt-and-peck QWERTY typists learning true touch typing for the first time. If your first formal typing classes were in, say, high school, you never really un-learned your wretched habits. (On typists who were trained correctly from day one, QWERTY has always been just as fast as alternative layouts, hence its market success.)

* I find Dvorak really is vastly more comfortable. I have RSI problems. The working day is a constant battle against pain and fatigue. I can type longer without fatigue using Dvorak than QWERTY.

* The "switching" problem is real. It only took me about three days to learn Dvorak well enough to regain my original QWERTY typing speed. It took almost two years to be able to switch between Dvorak and QWERTY at will, without resorting to hunt and peck. These days, I can could easily switch mid-sentence.

* The keyboard shortcuts problem is pretty much bullshit. I found that my muscle memory moved with the letters. One-handed ctrl X/C/V only mattered when I was typing with the wrong hand. (e.g. typing on the left side of the keyboard with my right hand.) I can even use keyboard shortcuts correctly when switching between QWERTY/Dvorak.
Very interesting idea!

I think that the approach is great given the fact that so many people go to chatroulette and end up looking at pervs. The filtering system can definitely give you the edge.

One thing I did not like was that upon visiting it immediately asked me to share my camera and mic. Perhaps a better front page with a lot more explanation (graphics can help) that would lead you to the 'chat' screen?

I can see the simplicity and I am up for it but a lot of people will think twice to click accept (for camera and mic) if this is the first thing that they are asked to do on a website.

Good luck!
On a Mac, there are a few options for Dvorak baked in. One is Dvorak with Qwerty shortcuts. So Ctrl-Z,C,V still work as expected.

Edit: Technically, they're Command-Z,C,V on a Mac.
Agreed. That all three current Law and Order series are being shown on some combination of three different cable channels, and in syndication locally, shows that the network brand doesn't matter on a per-show basis.

In fact, if it did, syndication wouldn't be successful at all. But we all still seem to be watching Cheers and Seinfeld.
That's actually one of the solutions suggested by the author. A rolling blockcade of police cars in each lane to regulate the flow.
Counterexample: Neuroscience. But that's the only one I can find.
I got something like a 10x performance improvement (for custom code parsing stock quotes from CSV) merely by rewriting Ruby's Date class in Ruby. The default Ruby Date implementation is awfully slow.
Yeah, "GroupTabs" doesn't imply anything related to what you do IMO. I agree that a name change is a priority.

Also, how is it different from Groupon?
Good clarification --- a quick read of the MSNBC piece leads you to believe that an on-board system was infected.
We are probably doing different things with our applications.
Good point, but I use a mac, and I think foxit doesn't exist on the mac.
I am pretty sure this is one of the many reasons. I recently came to usa from eastern europe, where I had car with manual gearbox (and with ceramic clutch, turbo, etc rough stuff under hood keeping you busy in traffic =)). I quickly get used to do smooth driving and continue to do it here in usa too on my automatic trans car.
I'm concerned that when cars doing this are the minority, with other traffic constantly going around them, they just become an obstacle in traffic. If you inspire other cars to change lanes to pass you, because you're intentionally driving slower, you may be making traffic less safe.
Another reason why you have no competition: there is no market.

Sometimes we delude ourselves that we found a niche no one has addressed when in fact there is no niche at all. This can be due to poor research, but as stupid as it sounds, it happens. It happened to me, at least.

I spent a lot of time building a product on zone diet just believing that because there were a lot of people following it and people buying products, there existed also a market of people willing to plan their diet with a computer program. It was my first software and I was very naive. But when I released it I realized that it was not possible to reach this market: there were no blogs about it and other marketing strategies were still unable to reach a significant number of customers. People simply did not bother about a "problem" that was just in my (and my friend's) mind. The customer where unreachable because the market was non existent.

So, if you find yourself thinking that you have no competition, go back asking the other question: is there a market for this?
If you're stuck in traffic for a long time, your leg engaging the clutch can get very tired. So you're constantly switching to neutral to rest your leg.

It's also not uncommon for traffic to go from stopped, to fast enough to warrant 2nd gear, back to stopped.
you will ruin your clutch bearing way faster. it's much better to keep constant speed (for engine/gearbox and for traffic in general). plus - you can't drive on highway on 1st gear. you still need to switch to upper gears.
Pretty neat idea, and I commend you guys for going up against Facebook, Foursquare, Gowalla, and Twitter who are sure to provide the exact same functionality at some point.

A few things I noticed right away:

1. I can't tell what city you're servicing right away, I had to search for the tiny address at the bottom of your homepage (NY I take it). You should make it very obvious where you're targeting right now. Maybe put the address in the hero section where you have the other event details, and perhaps provide an embedded google map too.

2. This is a minor design issue, but your main logo pushes your hero section down almost 200px. I would tighten things up a bit, but that's just me.

3. Design again: get a good designer to help you with your typography. If you're DIYing your design, look into grid systems, your alignments are headache inducing.

Where is your revenue coming from? Are the venues paying a fee for the potential of foot traffic?

Also, what would stop me from creating a similar service which simply queried Foursqure, Twitter, Facebook, Gowalla, etc. for location info and providing deals based on how many people checked in? It would essentially just be a deals site that functions on check-in services: you advertise a deal, you negotiate with the venue, and all people need to do is show that they checked in with one of those services.

Good work so far, though!

Hm, just so you know, never drive in first. That's just the one to 'start'. Either, you'll kill your engine too early.
Engaging the clutch every 10 meters is what is irritating. That's the point !
In my experience that is not the case. Specifically because jams are waves not just slow moving traffic. A gap will open up and quickly I can be in the 3rd gear to catch up. Of course as soon as I do the flow stops again. I could just creep forward in 1st and let the rest of the flow fill in front of me...

Manual transmissions are definitely hell during rush hour... but doesn't seem to affect people contributing to the waves in my experience.
Huh? I'm pretty sure both economists and weather scientists have tons of data but their theories to explain that data have been stagnating for a while now. Economic crashes and booms still happen and nobody knows why even though there is a lot of historical market data people still don't know what leads to them and how to stop them. When was the last time you got an accurate rain forecast? 40% chance of rain? What does that even mean? It either rains or it doesn't and I want to know exactly which and nobody will figure out how to do so anytime soon. While I'm at it I will throw the human genome at you as well. Big pharma was promising untold breakthroughs once we figured out the stuff people are made from but the results have been unspectacular since cancer incidence and whatever other incidence you can think of has been steady and even increasing. The only time big pharmacy companies made any breakthroughs were when they were trying to figure out something and accidentally figured out something else or invented some condition, ADHD anyone? The best treatment even after all the data collection and genome extraction still is prevention and your grandma knew that and she lived during a time when the number 23 counted for big data. So I'm not holding out my breath on any promises made with big data as a powerpoint bullet.

The main problem with all big data sets is that nobody knows how to handle them globally. All algorithms and theories treat the data locally and then try to collate the local pieces to get a global picture. This is fine when your data sets underlying structure is a graph or can be treated as some kind of graph. So the future doesn't belong to data scientists or statisticians but to the people that will figure out how to treat large non-graph like data sets in a meaningful way.
Thinking about the name...

As to Groupon, two big differences: 1) You are not paying for anything up front. You simple get percent off/something free/etc if enough people show up. 2) Groupon deals 'tip' if enough people commit to buy. We 'tip' if enough people show up.
Right, so if you cannot write solid C code, don't use a C based Ruby runtime, because not being able to write a fast library if need be cripples you as a programmer.
I wouldn't think too deeply about it, I read it more as an attempt at a wake-up call to all the right-wing supporters who insist that trickle-down economics works (even though it's never, ever worked). "The rich get richer and the poor get poorer" has been the mantra as long as mankind has existed on this planet.

Now I, for the very reasons you gave, will never support or suggest any sort of "wealth redistribution," it flies in the face of capitalism and has been proven to only breed discent and anger. What should happen is that the government stops treating the rich like special citizens. Warren Buffet has said before that he's paying fewer taxes now than he ever has in his life, and it's sick how the richest people in the country get the most help / special attention from the government, help none of them at all need.

The problem is that the GOP have a very long history of getting into power, then passing laws that help line their own pockets and protect their wealth from being "stolen" by the government (aka, themselves, it doesn't makes sense to me either). This view then leaves the other 90% of Americans as "well you should have tried harder, this is what you can do when you're rich!" while at the same time somehow convincing this 90% that the GOP in power is the best thing for them.

That's what I see when I read these kinds of articles.
I saw this earlier and this is why I think a co-founder should be a friend.

'What is a friend? I will tell you...it is someone with whom you dare to be yourself."

This is so important when working together, you need to be able to tell them exactly how you feel, to receive honest feedback and take it in the right way.

Brothers/Sisters and or friends, I think, make the best co-founders. As it is with these people that we can be ourselves which can only be good for your startup. If you go into business with someone then you need to trust them implicitly, if you have this level of trust in place then I firmly believe your partnership can flourish and therefore so can your startup.
In sql, that would be select from tablex where property1=x and property2=y and so on. Or a join. But that tends to be slow-ish?

Huh? It most definitely would not be the query you indicate-- that's a terrible, terrible way to store your data in this case.

What you want is a join between the Item table and the Property table, and that should be lightning fast, if you have your indexes built properly.

You neglect to say how many users you have, or how many concurrent queries you're expecting, or how quickly changing the data is, or what kind of hardware platform you're running on, so it is hard to talk about how easy/fast/scalable mysql would be.

I'd suggest you just code a prototype using whatever database server you are most familiar with, and run some benchmarks to test the scaling.
Why Facebook Wins Local: Over 50% iPhone App Usage is on Facebookk
Please don't alter the original title of an article (in this case "The Charitable-Giving Divide") to reflect your editorial opinion, especially when your new title is not supported by the content of the article. This article does not actually say that tax breaks for the rich don't help the poor, it says that rich people don't give as much to charity as poor people.

Personally I think it's true that giving tax breaks to the rich is not a great way to help the poor (i.e. the trickle down effect) but that's not what this article is talking about.

My point was that beautiful surroundings matter.

I assumed that comparing the US to the USSR was so ludicrous that my real point would be obvious. But the Internet is not a place for subtleties.
Upvoted, that's likely the correct answer :)
1. Thanks...we are getting people from all over the country (and world) registering...so we should make that clearer.

2/3. Design is a work in progress and yes it is done by ourselves. We have a new release of the index coming soon. Well aware of grid concept so will see what we can do about that.

Revenue is from venues for verified check-ins (GPS).

As to a similar service, nothing stops you or anyone else. The notion of culling check-ins goes against what we are selling the business on, which is bring in new people, not people who are going already and checking in. It would essentially just be a deals site that functions on check-in services That really is what we are. We are platform agnostic...just started with checking you into foursquare if you like automatically because it is most popular in NYC. We
