I like the idea of the product (haven't played with it yet though) and the pitch. Paraphrasing here, since I only watched the first half of presentation earlier: "companies spend a lot of money on people and their knowledge, but people leave and take it with them"/"a lot of answers are shared in a company but they're kept all over the place in email/IMs/etc" - again, really paraphrasing, but I think that pitch of keeping the knowledge you pay for inside of the company, in a central location, will push a lot of businesses to try it.

There are many products like this (basically any wiki software), but it's quite cumbersome for someone to go in and manually create/edit wiki pages. Every company I've worked with that uses a wiki usually has 1 person that has to go in to format and edit pages, because no one else will (or knows how to). Someone gets paid just to make and clean up the documentation. I think Opzi makes it simple for anyone to do that by just asking a question. I can't count how many times I've had to ask someone for info which they had in an email somewhere, and they'd have to dig around for it and forward it to me. Now they could just paste it into the answer section of the question I wrote, and when the next guy needs the same info it's all in one place. This software actually solves a real problem in both big and small businesses.
So why didn't the banks try to throttle the supply? It's funny, I don't recall any CEOs complaining about the economy being driven off a cliff in the runup to the bust.

On the contrary, I was astonished at their readiness to give money away. Don't you recall the endless stream of refinancing commercials on TV? shows like 'flip that house'? The way everyone and their dog suddenly seemed eager to have a realtor's license? The guy at my local pizza shop had his realtor business cards on the counter next to the delivery menus.

Edit: I see the truth is uncomfortable for some people. But the fact is that government promotion of home ownership is one thing, and instant approval of jumbo loans with 0% down are quite another. I got burned in a property boom when I was about 20 and this time I decided to stay out of the market.

Like a lot of Peter Thiel's smarter moves, this one is hard to explain without an awful lot of background exposition. Think of people as having to pass through a number of filters before they can do anything important with their lives. As the system becomes increasingly rigid, it filters out almost everyone. It's important to keep bypasses open at every point for people who are capable of dissent and not easy to force into molds. Intervening at the right filter point potentially has a lot of leverage.
That's very far from the truth. If TC was frequently accepting and then breaking embargos, then very quickly their sources of embargos would dry up.

TC very clearly announced to everyone that they no longer were going to accept unsolicited embargos. Their motive was that many of their competitors were breaking embargos by a few hours and then claiming it was accidental. The competitors that were breaking the embargo weren't being reprimanded by the PR firms, etc. at all. There was a clear advantage to breaking the embargo (more traffic, better ranking on news aggregators, etc.) and those who played fairly, like TC, were essentially being punished for it.
Is there necessarily a difference? Some fundamental problems, including such simple things as the physical 3-body problem, don't have analytical solutions. That doesn't mean that approximate solutions solve an approximate problem. Algorithms can be designed to give an approximation to the optimal solution of the problem, which is known to be achievable only through ultimately numerical methods.

I don't know whether that is the case here: it is possible that they solve a different problem from the fundamental problem. However, even in that case: if the transformations made to turn the fundamental problem into a more tractable problem are generally applicable, then is there really a difference between solving the fundamental problem and solving the transformed problem?
I think such people might be overwhelmed more than helped.
Instapaper. I know that's kind of a cop-out but incidentally it (and Google) have killed my use of bookmarks apart from a relatively svelte bookmarks bar. Instapaper is my reading queue, Google is my long-term memory. Bookmarks are more like shortcuts for me now.

The nice thing is that I can "bookmark" any link from any browser that I use, as well as twitter and RSS. And I have them instantly on my iPad, phone, notebook, or any machine with a browser without installing any software or extensions.
well clearly money is an issue for him so that is probably what helped drive his decision.

My chemistry is extremely rusty, but I thought that even if the reaction was at equilibrium, there is still a rate of reaction--it's just that the forward and backward reaction rates are the same, so there's no net change.

Yup. I turned it off on all my machines.

What you say sounds right, but it's not. Using some DB APIs you'll get back a list of results, and you'll know from the SQL that it will only have one result.

Another example is if you know there is a single item in a data structure, and use list comprehension to extract it. You'll end up with a list of one item.

These situations happen, and for good reasons.
"I'm a regular guy" -- This establishes a social status
you want us to see.

I said "I'm a regular guy" to prevent the counter-argument "Yeah, but you're special (as a HN reader, physicist, ... whatever) and do not represent the majority of te population we are talking about". Because all of us here aren't special: there are at least many thousands of people in the world like any one of us.

You are now interpreting my words based on what you expected to see, as you were primed to do by unconsciously having already accepted the premise in the article and not considering alternative interpretations.

You work in a non-profit? That's because you wish to signal social standing. You work at a hedge-fund and make lots of money? That's because you want to signal social standing. You work at a startup? That's because you want to signal social standing. You work at a MegaCorp? That's because you want to signal social standing. The analysis is meaningless. It's Freud all over again.
hah, I'm trying to turn it off but finding it is impossible. I save my preferences but it's still there.

That's where the nonblocking comes in. It relates directly to scalability. It doesn't improve performance, but it allows more requests to come through while you are waiting for external resources like databases to return results (by far the most common cause of slowdowns on web servers).

Performance and scalability are not always a tradeoff. When you increase performance at the runtime level, you don't decrease scalability. However it allows you to serve more requests in the same amount of time.
I listen to http://www.stereomood.com - pretty useful app. Songs are tagged by "moods" (happy, relaxed, sleepy, ...) which make it easier, for me, to choose which kind of music I want to listen to.
I hate to be pedantic (publicly, at least), but I believe you meant to say that your clients spend big on AdWords, not AdSense, or have the two become somewhat interchangeable (honest question)?
Many medical plays require large capital investment. Regulations, bizdev, and long sales cycles are all huge barriers to entry. Advertising to Doctors is incredibly expensive, and it is hard to monetize consumer applications that will scale (some people are trying their hand at medical compliance, but I haven't heard of a great business model yet.)

23andme is a great medical startup, but it is a capital-intensive business that has to spend time and money on Washington.

We (Epocrates) are working on an Electronic Health Record system as an additional product. Our core team is small, but we have the resources and brand of a midsize company.

We're a mixed RoR/Java/Mobile shop. We're currently hiring RoR developers, so please feel free to contact me if you are interested in this space and want to make a real impact on US healthcare.
> EDIT: Also, automatic vegetable/fruit recognition is actually in production in some supermarkets, for weighing/pricing. (I saw this in France.)

I saw this in France. It sucked. I wish I'd documented it better, but as far as I could tell, the algorithm was "display the top five fruit/veg with a similar hue," i.e. you put on a courgette(zuchini) and it offered you--cucumber, lettuce, green pepper, cabbage, grapes. Pinnacle of machine vision algorithms, it ain't.
if you don't have much experience with Scala, i'd suggest to rather stick to the things you already know. it takes awhile to really use its benefits for your own good.

it's completely possible to write the code in Scala that would be quite similar to the one you write in Ruby (especially JRuby in that particular case), although Scala allows a lot more, in terms of FP, threading and so on. if you're building a really high-tech startup, and your most important use cases are bound not only to front-end, and you need a reliable base for data processing, manipulation, hardcore server-side, use Scala. if it's going to be just a website with _some_ features that require a lot of processing, use RoR and maybe some Java/Scala for your backend processing.

I can't see any obvious benefits out of using Scala/Lift for mere website building against Ruby on Rails, unless you're making something i was talking in that topic...

Can someone point to some more complicated apps that have been built with Node.js? Seems like people always point to some application to validate that Node.js is real and a viable substitute to Rails/Django/Whatever, but then those apps turn out to be incredibly shallow.

Even this article's proof positive is a one feature ultra simplistic web app.

Where are the Amazons, GitHubs, Diggs, Onions, etc..

Considering that most sites will have to scale on features before they have to worry about scaling on performance it seems like too much focus is put on the groovy non-blocking nature of Node.js.

If you want a reasonably new laptop for $800 or less, it won't be a Mac. (I'm not a hater, I'm typing on one now, that's just the way they are. And I hate that statements like that need to be justified.)

HP is far and away the most common brand in our shop, and many of them for the results of design defects. HP has taken to cutting the wrong sorts of corners; they're using cheap foam thermal pads on their GPUs, no shock bumpers on their hard drive mounts, that sort of thing.

The battery life you're looking for will probably mean a smaller screen size, not much bigger than 15".

http://dealnews.com/ has a pretty OK-looking Dell Latitude for $697: http://dealnews.com/Dell-Latitude-Core-i7-Dual-2.66-GHz-16-L... -- Core i7 is real nice, although that'll have an impact on your battery life. I don't see anything there that Linux should have trouble with, and we've had pretty good experiences with Dell so far, especially given their price.

I've had my eye on an MSI lately, but Lenovo is still a really good bet when it comes to reliability: http://dealnews.com/Lenovo-Z560-Core-i5-Dual-Core-2.53-GHz-1... -- Core i5 at a slightly lower speed should give you a little better battery life, and Lenovos are typically fairly reliable and Linux-compatible.

Oh, and if you can scare up the extra cash for it, replace your hard drive with an SSD as soon as you can. Your disk space will suffer (badly), and it'll cost a lot, but it'll save you a fair bit of battery life and you'll be thankful for it the first time you drop your laptop. My laptop travels all over the place with me all the time, and despite having to suffer with only 32G of disk space, the SSD in it has saved my butt more times than I care to count.

This is a space I've been thinking about and coding for.

I have not been able to test out Opzi, my comments are based on using Quora and the work I've been doing.

I think that the wiki model of aggregating knowledge has certain deficiencies that can be improved by systems implemented by companies like Quora and Opzi.

One of them is the identification of experts after the fact.
Take forums and wikis for example. A user is identified as an expert only after contributing to the system.

With systems like Quora and Opzi, experts and their knowledge is focused early on.
This is done formally by participants filling up their profile and expressing their areas of interest.
This is done informally by askers directing questions to other users of the system.

Identification of experts early on is really useful because it helps those who desire knowledge to pull that knowledge out of those who have it by initiating contact as opposed to a wiki where those who desire knowledge wait around for those experts to contribute.

Asking is a great way to pull knowledge. It is active as opposed to the passivity of waiting for the required information to just show up.

One could possibly add game mechanics to 'encourage' experts to contribute to a wiki or knowledge base. By why go the roundabout way. Why not just ask the expert? I believe most people within an organization would be willing to respond if asked to share.

Second, don't underestimate email support. Lots of knowledge is trapped in email. If I enter an email thread late, I would need to read a whole email thread to understand the context of the discussion. And imagine if a responder had deleted the previous email when replying. The previous thread is lost. That knowledge is 'lost'.

Being able to direct a question using email, collecting the responses and aggregating it on a single page will be very helpful.
"long time" git-achievements user (half a year I guess?) here.

1. The iTunes Store is pretty big by now.

2. Apple's Genius recommendations suggests that they are, at the very least, toying with this concept as well.
It can be used for just about anything except maybe low-level operating system stuff.

"What should it be used for?" is a different question and depends at least somewhat on your preferences.

I go to Java when I want a desktop application that should be portable, doesn't need to be lightning fast, doesn't depend on any low level operating system stuff and that I don't mind losing pointers and memory management for. In other words, most of the time I'm writing a non-web application, I go to Java.

I personally don't like using it for web stuff except where small applets are concerned. I've had issues with it (it including Java, JSP, etc) and generally find it to be too heavy and not practical for web development. But that's just my opinion.
Thank you, Denny. That's a good point about self-employment tax.

Yes, that was my plan, to do it myself, but I find that I'm spending quite a lot of time on busy activities like this - as a follower of MVP/Steve-Blank, I'd rather be out talking to (potential) customers.
I have not done thorough research, but based on what i feel\know, i have following opinion/views.

1. Analytic part : It should not be hard to implement a simple application to generate good figure, pie charts, etc. (much easier than screen/data reading part)

2. Image processing as sole innovation. :
Application will solely be based on it as prime innovation/challenge, but that is not so bad thing. Other solutions will be based on wi-fi, blue-tooth, usb, etc and they will have their own limitations (configuring, downloading, connecting etc). Ease of use may decide the winner. Only if all fitness equipment manufactrs. join and develop a universal application targetting large number of machine to connect using blue-tooth, wi-fi etc, then it may be better solution. I donot see this thing happening very soon. (span of 5 years, my estimate). In this time, this application (based on image processing), if it can establish itself, it may possibly be hard to replace it. It would have already created customer base for itself.

3. Application will target low income group.
May not be true. If application works as i see it should, i feel it may be used by all groups.
To be more specific: lead-acid batteries are dead simple technology. Reliable, provide tons of power, etc. However, they take forever to recharge (about 5x as long as they take to discharge) and they are heavy. You can build an EV by just attaching a motor to an axle and adding enough lead-acid batteries until the thing has a decent range, but you'll create a horrible vehicle by the standards of today's commuter automobiles.

And then you've got a vehicle that's mostly batteries and little else and has horrible acceleration and top speed. If you use more modern batteries (NiMH, LiIon) you improve the situation greatly but it's still a troublesome equation. Batteries are heavy, putting enough in a vehicle to give it decent range and performance is a struggle to avoid compromising vehicle comfort and safety. And then if you use advanced materials to make the vehicle lighter then you end up raising the cost significantly.

The good news is that technology is catching up. Hybrid technology is maturing and with it plug-in hybrids, fuel-cell vehicles, and entirely battery powered vehicles are becoming feasible, even if a bit on the expensive side. But the even better news is that as more money gets spent on R&D the technology will get better and cheaper, until it's a legitimate competitor to gasoline.

The bad news is that currently the concentration of hybrid / electric vehicle development is mis-targeted at small, commuter vehicles (making the small slice smaller, basically) when they really need to target bigger vehicles (long-haul freight, etc, although fortunately there are inroads being made there). The far worse news is that at best all of this is just step 1. Even if suddenly overnight every automobile was replaced with s shiny new electric vehicle all that would mean is that we'd transferred the problem to the base power generation infrastructure, which today is dominated by coal and oil in much of the world.

I ran a managed hosting company (dedicated servers and colo) for 6 years.

Because of that, I'm pretty picky about where I host.

I currently have my sites at ServInt on 2 VPSes (a Signature VPS for my production sites and an Essential VPS for testing my new startup company.)

The primary VPS serves about 2,000 pageviews per day with no complaints.

My advice, having been in the industry for many years:

1) NEVER use shared hosting for a startup company. I would always budget and start with a VPS...even a small one. Shared hosting is likely to fall over at random times and it often fails at the worst times--when you launch a product and get a ton of visitors, for instance.

Shared hosting is fine for things like small company blogs, etc. But not for a scalable business.

2) Go managed, unless you want to wear a sysadmin hat as well as a developer hat (hint: you probably don't.) I recommend letting the hosting company do updates while you focus on writing code and testing.

3) DON'T cheap out! Hosting is not a place to save money. $50/month for a managed VPS is completely reasonable and is well worth the extra $40 over shared hosting if you need to scale. You do not want to have to move your hosting when you're in the middle of a really good run with clients.

I picked ServInt because they have been in business since 1995 and they host some pretty large sites. Their reviews are overwhelmingly good and their prices are reasonable. Their support responds quickly. I recently put in a ticket asking for server monitoring to be installed. I know this would have taken 1 hour+ of my time (and I used to admin servers for a living!) They not only responded to the ticket within a few minutes, but had monitoring installed quickly.

I cannot stress enough that it is worth the extra money to go with a higher-end hosting solution. Yes, inevitably there will be "But shared hosting works for me!" replies. It works...until it doesn't. You get an Alexa top 10,000 site, and even with good caching, your site doesn't work so well with shared hosting--then you have to scramble around and muck with switching providers when you should be working with your new customers and working on your product. That's why I don't even recommend starting with shared.
They did okay with engadget and the rest of Weblogs, Inc.
That's a good plan too. They'd probably go for it. In the commentary on the survey, Eliezer (founder of the site, also present here) doubts the estimate too.

It's worth noting that one of the central tenets of LessWrong is that it can be just as bad to underestimate one's knowledge as to overestimate it. As a result, some things which look like boasting are really just attempts at accuracy, carried through to a level not normally seen in polite discourse.

Other things, of course, are just boasting.
