I think I know what you are getting at but I think we are talking about two different things.

That kids learn concepts from high level physics and maths does not mean they learn formal math.

I am not saying that they need to learn formal math (in fact there are plenty of arguments against spending so much time trying to teach kids any math)

But it's important to understand that if everyone have to learn concepts in their own way they will loos the ability to communicate with each other.

The ability to transfer metaphors from something we understand into the world of Mindstorms and through that develop conceptual understanding of various areas does not necessarily transcend into understanding of math.

It might though create something else and quite wonderful. But formal math it probably wont be.
I have only one question: how to get an invitation to the interview if you are single founder (like Dropbox)? Looks like "single founder problem" is a flaw in YC's business model, because your biggest hits (Dropbox, Greplin) all came from initially single founders.

Well, I know that the odds aren't good for single founders...But the problem here in Russia (where I'am from) is that it's virtually impossible to find an entrepreneurial-minded hacker who's ready to put efforts and passion into a such risky thing as startup. We don't have such startups culture you have in US. It's very tempting for smart ppl here to just get a day job with a nice salary and relax. Or they already have girlfriend/family and thus will not move anywhere.

But I'm pretty sure I'll find a co-founder when I'm in the Bay area. But looks like it's chicken-and-egg problem. Actually I think the problem with single founders is exaggerated a bit. If it's all about people then great ppl eventually will find a great co-founder if you give'em a chance.

Since you can't downvote, you could try explaining your position.
I didn't know it was possible to switch. I'd be interested to hear about the process you took and the outcomes and side effects from it (pros, cons, etc).
Okay, my mistake, I apologize. One of the problems with living in a fast-moving world is that sometimes I lose track of what is obvious and what is not.

I just saw a demo of Eclipse Orion:

http://jaxenter.com/eclipse-orion-the-new-ide-paradigm-33431...

... so at the moment it is blindingly obvious to me -- apparently so obvious that I forget to mention it to other people -- that you could easily build an HTML5 app that allows students to edit and run Javascript from Safari on the iPad. Having grasped that, I have already started assuming that such apps exist and acting accordingly. But I'm ahead of myself, so I'll concede: It might be impossible to usefully write executable Javascript on an iPad today. We might have to wait a few more weeks.

If iPad-friendly HTML5-powered Javascript editors don't already exist, I don't know why not. Perhaps there is too little demand. Perhaps we were all waiting for something like Orion to provide the proof of concept. Perhaps nobody has gotten around to it yet. Perhaps the founders of the appropriate startups are still building it and haven't launched yet.

Or perhaps nobody wants to edit code on an iPad when PCs are a dime a dozen. I can hardly blame them for that. I like real keyboards for hacking, just as I like oscilloscopes for designing audio electronics. But it's not Apple's fault, exactly, that the iPad isn't particularly well designed for typing code. They make other machines for typing code. The iPad is designed for iPad things, just as my car is designed for daily driving and not for stock-car racing.

Show HN: Word/Image game - Woordplay
http://woordplay.com

I came up with an idea to test how people read words, and whether they can interpret meaning and quickly extract letters and form other words, then wrapped it in a game mechanic.

The concept might seem slightly strange, but after seeing those emails a few years back where the first and last letters are in their correct places, but the other letters are jumbled, I thought people might go for it.
You simply take the first letter of the object, colour or flag in a picture and write it down. You then do this for a string of images to form a word (players can then score points for doing this), and there are groups and leaderboards for some competition.

It's built on a standard Rails/MySQL structure, and can be used on the desktop or via a mobile web app, plus uses Twitter for user sign-up/sign-in.

Any thoughts and feedback is greatly appreciated - it's obviously still being worked on, but some pointers now will ultimately help!

Thanks!

This is just one of those cheap, direction-less advice blogs that hopes to get a book deal. "My goals for the short term are to get back to doing productive freelancing work for good people while finishing up my first book."
Is that really right tho?

Lets follow the waiter example. In order to skim the card number they'd have to put the card down, pull out a pen, and copy it. Likely within plain sight of their employees. With a skimmer they just discretely 'double swipe' the card and they got what they need. It certainly makes it a simpler attack vector.

Now you don't really need square to do this. There are plenty of magnetic card readers out there (I seem to recall someone got caught doing precisely this with a PDA of some kind). That doesn't mean that Square should make it simple. Why not provide some sort of encryption to the communications layer?

"general rpc servers for solving specific problems using in memory data structures (e.g., who qualifies for a match search given dozens of constraints and millions of users; what your match score is with 10,000 qualifying people, given you've all answered hundreds of different questions each on average) ... Great tech is available now, serving is cheaper, and you probably don't have the computational workload OkCupid does."

I know people who have used OKC before. OKC users in my social class (male, white, educated) ignore the match percentages, because the SNR is really low. They just plow through all the search results of people to find good pictures and interesting profiles.

So, I'd speculate that match-percentages are a marketing thing, and that they know they made a weak business decision which required lots of computation and now they're stuck with it.

I'm probably wrong. Maybe the long-tale users pay attention to match-percentage.
Actually Greplin had 2 founders initially. And though Drew was a single founder when he applied, he had found a cofounder by the time the YC cycle started.

The trouble with the plan of finding a cofounder when you get to the Bay Area is that you'll then have a cofounder you've only just met. Empirically that doesn't work well. Cofounders should have known one another for a while.

You must have friends of friends who'd start a startup with you.

Wow, that's a bit misleading. The only way you to "steal" a website is to copy all the files then delete them, maybe. A DoS might "steal service", but that's about it.

What's wrong with "On one hand, web sites can be like stores, and taking them down is obstructing commerce, in a way." ? Are people not capable of handling nuance and ambiguity? Must everything be forced into "theft"?

Being able to disappear/discard history has significant downsides, too.

Regardless, you can rollback changes in subversion without bungling future merges.
No, it's not a problem. This happens to lots of startups even after we fund them.

If you can talk intelligently about why your previous project isn't working, that's actually a point in your favor.
I understand SCVNGR's thought process behind this and appreciate the fact they are going after a major inherent flaw of other daily deal sites (not generating repeat customers).

However, I think SCVNGR will find they have the same problem. Even though they claim research shows that a customer who visits an establishment three times is a "regular" this doesn't take into account that customer is used to severely discounted prices. When someone is used to paying 75% off, I think this is a huge barrier to overcome in order to get them to continuously pay full price.

I had a scenario a few years back where I interviewed with another company in which the person I interviewed with was friends with someone I worked with.

As part of their due diligence, they asked that person about working with me, and that person then proceeded to tell my boss that they heard I was looking for another job.

My boss then spent the next few months transitioning all of my responsibilities away to other managers, basically leaving me with no responsibilities.

Thankfully, I transitioned back to being a consultant, and all of them were fired; but you don't even need a counter-offer to be marginalized. Sometimes, just talking to another company is enough to do it. So be wary.
Imagine an Amazon delta dweller who suddenly got a $50K estate and moved to Miami. The choices of goods and services are nothing like he seen before, and their cost is nothing he can relate to.

How many investors only invest in stocks? I personally have more in ETF's and mutual funds than single stocks. How about the bond portion? It seems weird to apply tons of analysis to only a portion of someone's investments.

Also, since it seems on the surface to be like Morningstar's portfolio x-rays, you should have a good answer for how it is different.

Oh, and "analyzation" isn't a word, is it? How about, "portfolio analysis tool".
While SIP is widespread and the only commonly accepted VoIP standard (besides death protocols such as H.323) the whole protocol is just one big mess.

I think the only way to get around the awfulness of the payment systems is to break completely from the extant banking system and to find a way to define yourself outside of the normal regulatory definition. It's just too restrictive to allow us to do anything we want if you have to work with VISA or MC or even just follow the normal legal procedures necessary for a bank. Really there's no reason transferring money shouldn't be super easy and simple, and cost barely anything, except that banks like money and they like using regulation to stop new competition and innovation.
Perhaps a very slight one-- a few percent-- because we know visa problems add to the drag on a startup. But we've funded a lot of startups from other countries, including some of the most successful ones. In practice, how good the founders seem dominates every other factor.

The Fee Fighters tool is great, but they don't take into account how much better of an experience Square is over Verifone. Go take a look at the screenshots of Verifone's Payware Mobile app: http://itunes.apple.com/us/app/payware-mobile/id347863505?mt... versus Square: http://itunes.apple.com/us/app/square/id335393788?mt=8 – On top of that, Square's interface on iPad is just as beautiful.

Square also offers other features like text message receipts that Verifone doesn't, like SMS receipts.

While fees are definitely one of the most important things to consider, ignoring other aspects of payment systems is short-sighted. It's a shame that Fee Fighters seems to be using just the 'checklist features' model of comparison.

Nah, that's a common enough reaction. Me, I dropped out of two high schools, was able to pick up an alternative high school diploma at age 16 or so anyways, got a near full ride scholarship to UMass Amherst at 17, left there at 19, have held down a variety of self-employed or owned gigs in contracting, project management, sales, marketing, logistics, and a whole variety of other things. Studied business at Boston University later, paid cash for everything. Lived, worked, or traveled through 40+ countries, been around Asia the last 15 months. My last work was in hospitality/tourism. I'll make at least $65,000 this year (just inked a $65,000 contract, but the cash isn't in the bank yet so no partying yet), maybe a lot more depending.

> I'm the type who prefers the advice of people with a track record of success–or, at the very least, who have tried and humbly reflect on their failures. With details.

That's totally fair. I've written hundreds of posts - did you go through any of them? I've written detailed guides on lots of stuff, lots of personal experiences.

This is actually a tricky thing about writing, you never know which piece you write will be the first one someone sees. You write a heavily assertive one, someone thinks you're a jerk. You write an introspective one, someone thinks you're narcissistic. You talk about what you've done, people think you're bragging. You don't talk about what you've done, people think you're full of hot air.

Great comment.

I get pitched a lot to be a technical cofounder, and I put a lot of thought into assessing the biz skills of a potential sales/marketing/bizdev cofounder.

As you said, some ideas may be better suited to having someone with a sales background as a co-founder while others for someone with killer marketing skills.

And I've also found in the past that I have a different working dynamic with sales vs. marketing people as they often complement/overlap my skillset in different ways.

Another random thing to add regarding founder dating from the techie side is an awareness if someone is giving off the vibe that they're really looking for their first engineer even though they say they're looking for a true cofounder.

Finally, I try to distance the individual from the idea and ask myself, "Would I want to still co-found something with this person if things don't work out and we have to do a hard pivot from the original idea?" I would rather team up with someone great on a marginal idea that may evolve into more than someone just because I think the idea is killer. Most people I know in Silicon Valley have a million ideas on the backburner anyway, so it's a red flag to me if the idea interests me more than the person.

The first bolded sentence has it very very wrong:

> I believe the reason you see sites without ads as superior on some level is because the absolute-highest-quality writers usually don’t have ads.

And then he goes on to list a bunch of tech entrepreneurial writers. Well I hate to break it to you, but those are not the definition of "the absolute-highest-quality writers". Sure they are very good writers, but their secret sauce is that they are great businessmen too, and so their ideas are valuable if they do any reasonably competent job of communicating them.

More importantly, these guys make their money (and a lot of it) elsewhere, so it would be a terrible idea to dilute their brand with cheap ads that were irrelevant to their net worth.

It might very well be true that the best writers don't have ads on their site, but my guess is because you can't really make a lot of money from ads unless your audience is massive, and frankly, the audience for very high-quality writing is disturbingly small. By and large people read for content more than quality—this thesis is supported by the fact that the OA considers entrepundits to be the "absolute best". The absolute best writers are probably people who do it professionally, and to do so professionally requires working for an organization that is extracting the true value out of great writing. That is, either a high-brow periodical, or a book publisher.

No. Perfectly reasonable question.

For every x weird posts, he has a real gem, something that no one else has mentioned that really gets you thinking. Also, he is more likely that almost any other poster to "push the envelope", bring up something that runs counter to the group think often found here.

If he posts something I don't get in the first 3 sentences, I just hit the back button and decide to read him some other day. It's usually worth it.
