As they put in their update, they aren't able to track 3rd party services. Considering 50% of all Twitter users use Twitter through 3rd party applications, that is probably a huge chunk.

However, I wouldn't be suprised if Twitter doesn't have a good retention rate. Especially if you don't go into it with friends, starting out on Twitter is a little hard, and takes time to build up your stream of information and relationships with other people.

I believe language and effort are the two main factors for a good signup form. Language means clarity, which makes doing the work easier. Minimizing the amount of effort that actually goes into filling out the form is really important too though.
I think if the user thinks they are suddenly being tied to a service may push them away.

The services that use the 'save my info for later' technique are most likely seen as easier because it is similar to how you use your local computer. You don't have an 'account' on your laptop. (Well, technically you do, but most people just believe that is just a password) You simply save something in your documents for later. By making the user believe that they aren't tied to anything, but just saving data for later, you can make them more likely to store their data on your servers.
Congrats to MLB!

So, what does this mean for the iPhone gold rush for indie developers?

Well, it'll take a perfect storm of loyal user base, deep and frequently updated data, a very useful and functional application, and a price point that the market is willing to bear because of the previous points.

In other words, good luck!

You'll probably have moments where you're not sure you're doing the right thing by homeschooling, or that you're not doing a good enough job.

Specifics vary. Whoever is the main hsing parent will certainly have days where nothing goes right and everyone quarrels. Several of those in a row and you'll wonder if hsing was the right choice. Sometimes parents get disappointed that their kid isn't learning fast enough or is resistant to teaching. If you lean toward unschooling, you'll probably wonder if that's really "enough" to equip your kids for college/adulthood. You may worry about inadequate socialization. Any area where your kid seems to be lagging behind his peers will probably cause you to question yourself.

Once you start homeschooling, it's all on you. It's a lot of responsibility. You'll worry, at least some.

From what I've seen, it's common for new homeschoolers to have a big crisis of confidence a few months in, for one reason or another. Some decide it's not for them at that point.

Lesser moments of anxiety occur more often. For some folks, nearly continuously. :) We worry about some thing or other every few months. Sometimes we make some changes to try to address it, sometimes we decide it's no big deal or at least nothing that needs immediate fixing.

Certainly, f=ma, but with all else being equal, I'd say that an increase in lever length (hip joint to footprint) MIGHT explain an increase in speed.

Consider: an inch of shoe is probably lighter than an inch of leg. I resisted the urge to call it "an inch of man" - you're welcome.

An additional factor: extra cushioning and the different shoe shape resulted in the runner not bending his knees as much. This could result in increased lever length as I described above; it could also explain the knee pain: the knee joint was experiencing increased shock during impact with the ground.

If nothing else, implementing a reasonably efficient but basic Scheme interpreter is a short exercise that can be done in a pinch. "Reasonably efficient" is a consequence of the proper tail recursion.
I'm think you are oversimplifying the problem. Web search is about the long tail you need breadth in your index. It will cost quite a bit more than a couple of bucks to do (storage is not that cheap, nor is cpu), and you'd have to do it repeatedly (and quickly as I mentioned above). And then of course you'll need enough computing power to perform the actual searches and run hadoop on your web index.

Answer = Oprah factor

She did a terrible job using / teaching her audience about it, and all the moms at home give it a shot, don't get any value out of it, and quit.

Not to single out just Oprah, celebrities in general have done a great job decreasing the value.
Examples of their creations:

Navistar and Tempstar, Telegy and Telegent, Verbex and Azurex, Nortel and Meritel.

They do sound like they were created by brand consultants. Meanwhile Yahoo, Google, and Amazon are doing ok just taking whatever the founders picked.

Love the price breakdown, jg!

I'd agree with everything except:

1) Basecamp -> Google Docs (I know you said this...)

2) Pivotal Tracker (honestly the worst UI I've ever seen) -> Lighthouse (or Github Issues if you're really cheap)

3) Slicehost -> Linode (but I'm probably biased and I run Rails)

4) Probably not get a CDN up front.

5) Would add Balsamiq Mockups to the list of things to get - true gamechanger

$$ raised is a success in a way. I'm sure most people think Facebook has succeeded, but they're a long ways off from paying back their investors.
Yes. We have no idea yet what the returns might be. Quite a lot of the startups we've invested in are doing well, but I've never even tried to estimate what our shares in them are worth.

We'll start to have some idea how we're doing financially in around 2012. I feel optimistic we'll make money, but I never think about it. I just focus on the individual startups.

A must read for anybody interested in education and development related matters in third world countries in general and in India in particular:
http://www.deeshaa.org/2007/02/07/thoughts-on-the-education-...

The gist of the matter is that OLPC is a bad thing for India at large. Why? because India doesn't have the resources. There are thousands of schools without a blackboard and a chalk mainly due to lack of resources and corruption in the Govt. And in general teaching can be done without computers. Now if a country that can't afford blackboards and toilets goes shopping for computers, it comes at a cost: more schools that would be without teachers or any other basic amenities.
Thanks man.

The thing about Slicehost, and I just had this convo on #startups, is that they can move you to metal when you get too big for your britches. Also, Linode's biggest box is 2G, which is a serious upper limit.

I know you're a mac guy, but you should look at Axure for prototyping. It's ill as all get out.
Most applications from known sources sell pretty well. Especially if the user already uses the product, and this is simply an easier way to use the product. In this case, it is sports coverage. This is why most of the applications on the app store don't sell well. They are all random developers that don't really have a big name to consumers, so buying their application at $10 is a gamble that some just aren't willing to take.
In his (her?) defense, he didn't say "search", he said "index". There's a difference!

It's funny you mention the "Oprah factor". I'd been feeling more and more skeptical about twitter the days leading up to the day Oprah showed up there. That was the peak of the celebrity wave, and it completely did me in. That night I deleted my twitter account. I still use the the API+Search to track what my close friends are saying, but have no interest in posting updates any longer.
I was there at the launch!

Some of the ingenuity that went into building a model rocket of this size is remarkable. Talking to some of the folks involved afterwards, it turns out that the mechanism to separate the rocket into two parts at apogee was built from car seatbelt tighteners and an airbag.

It was heartening to see how many people showed up -- easily a thousand or more.
ha, well op said build a "search index".. its not much of a search index if you can't search it :)

The point is, the name is overrated. Think of the Wii, how people hated the name. A few months on, who cared? They wanted to buy the widget, and never mind what the widget is called. The name does not define your product; the product defines your name. Anything else is just voodoo.

Paying for someone to name your car model "J30"? Oh come on.

This reminds me of the (semi-apocryphal) story of the creation of the Euro symbol. A European Commissioner, Jean-Pierre Malivoir, was given a big pot of money to hire a designer to come up with a proposed symbol for the new currency. He thought it was a total waste of money, and sat down and came up with the early version of what is now the Euro symbol himself.
I disagree... A clumsy GUI is no excuse to dismiss the idea. We can always make a better GUI.

The point is this: If we can let the computer do the work, including during programming, then maybe we can focus more on design of the logic rather than keeping the entire programming model in our brain all the time and having to build a new one every time we hit new code.

Its definitely a very nice idea. Actually I can think of one program I worked on which is really a logical configuration tool which could use such a language instead of what it does and it will be simplified many times over.
The landlord could kick you out, forget to pay the water bill, etc.

Actually, most areas have tenants rights provisions that prevent a landlord from doing these things. Hence, your rights as a renter are protected.

No such laws exist for software.
Perhaps a better metric would be tweets. Should be easy to scrape everyone's first and last tweet. Though there's lots of spam accounts now too.
Wonderful document. My favorite quote, which apparently has been cut out of this newer version:

That's your Open IDs provider's fault, not Stack Overflow's. Yeah, they may suffer a little but not enough to be responsible for a shoddy provider. But with how many providers are out there, it should be easy enough for you to use another one.

Startup Internship: Acquia Searching for LAMP Developers
The Web has seen its share of hype, but I think Twitter is pushing it to new levels.

Most people don't really need or even understand Twitter's functionality. Those who do are getting it from Facebook. But the best part is that the numbers actually reflect this. 6 million users in 3 years of constant hype is not a high number. (Just to put it in perspective: I once contracted for a company that produced a shopping toolbar. Nothing viral, no PR to speak of, nice but not amazing functionality. 3 million downloads in a year.)

Any journalist could have deducted as much just looking at the user count. A slightly more serious one might actually use it for a while, and see how many of her followers are "SEO marketers", brands and other spammers. And yet the puff pieces continue. Personally, I think the best value we're getting from Twitter is in reminding us how incredibly poor, shiny object driven our media is, from Oprah all the way to Maureen Dowd.
Clarifying what I said, I meant "building a good search engine" is hard, while using an index to make something faster to find is easy(ier).

I agree (with the previous poster) that indexing parts of the web and making it searchable is pretty much a solved technical problem. There are thousands of people who could pull this off. Heck, I probably could if you give me the hardware.

Now doing it cheap, scalable, etc... it's hard. And making it a good experience for the user is pretty much a war on its own. Fighting spam must be pretty hard...
This was a lifesaver during my networking class at UC Berkeley. I think I spent more time referencing this than the textbook, although not much substitutes for just writing code and seeing what happens.

Of course people will pay $9.99 for software! In fact, they are often willing to pay a lot more than that - as long as the value it provides them exceeds the price. (And the MLB app obviously does.)

Doesn't matter that it's for the iPhone.

If all you're selling is something that makes fart sounds, you might be happy with 99 cents. But if your software kicks ass and can save time/money/headaches and/or fix problems or help people make more money, 99 cents might be cutting yourself short.

For really large databases, SSDs aren't cost effective (think multi-terabyte). For the smaller sized databases, most will prefer a hybrid SSD-RAID solution(like Sun's storage appliances) for cost again.

Toku is targeting the niche of people who 1. Don't give a damm about ACID. 2. Can't afford hybrid SSD solutions.

Toku's indexing technology would be worthwhile at the higher end also, and people with multi-terabytes of information at that end usually use a database as a persistence backend rather than a ACID RDBMS. (think FACEBOOK or your-next-large-startup). Those with a need for ACID, are already running Oracle (which lacks this technology AFAIK). I sense an Oracle-buy-me exit strategy.
A great idea while you're getting your site off the ground is to use Nearly Free Speech [1] as your host. While it's not the best deal for a busy site, a low-traffic site costs $1/GB transfer, with no bottom limit. I'd also suggest using something like OddCMS [2] that serves static content, so you don't have to spend money on a database.

Obviously, using these instead of Slicehost and MySQL (or similar technologies) will restrict what you can do with your server, but when you're really shooting for low price, they can't be beat. I've paid two cents (yes, cents) for the last two weeks of hosting my software company's website [3] (~500 views/day).

Are famous people super conservative when it comes to the latest Web 2.0 phenomenon?
Famous people for example are joining twitter pretty late in the game.

It almost seems as if they do not want to look foolish by taking part in a phenomenon that they do not understand well and/or that may ultimately fail.

Or maybe they just don't have the time to experiment with the latest ideas.

Now that Obama is world famous, it would be interesting to see if he becomes more conservative in his use of novel Web 2.0 services.

What? Google makes a custom political map for China? A couple of years ago, they used to claim that they don't make custom products for any market and product rollouts are always worldwide.

Compare with: http://maps.google.com/maps?f=q&source=s_q&hl=en&...

Note that it's not just a matter of translation. First, they list Taiwan next to Hong Kong and Macau as if it's a peripheral part of China (this is surely China's wish, but the reality is that Taiwan is an independent democracy).

Then, there's a line in the water to the east of Taiwan and extending elsewhere whose sole purpose is to imply regions to be part of China's territory that are not or are controversial. This line isn't used anywhere else in the world, such as say, in the Caribbean, where the boundaries of different islands might not be clear.

I guess Google wants market share in China bad enough that they are willing to proffer multiple versions of truth.

It's funny how none of you even question what a search engine should be. Everyone gave in to the concept that you want to find web pages.

Wolfram is the first one to say that you need an answer engine. The web has data, you want answers, not necessarily an URL.

When you discuss indexing, you imply keyword matching. That has nothing to do with Wolfram Alpha. If anything else, this discussion was a great way to question conventional wisdom.

Vim, Emacs and Textmate aren't IDEs per se. They are general purpose text editors optimized for editing texts (although one could argue Emacs is an OS :))

The nature of Python is such that it's not possible to determine precisely all members of an object at compile time. I've used PyDev and I discovered that auto-completion in Python actually annoys me because it doesn't work all the time.

For example, in Python you can add a method with a simple x.__dict__['method'] = some_method, not to mention magic methods like __getattr__. The trouble is many Python modules add members to classes through various meta-programming techniques. When using PyDev searching for a member name, instead of using the API's documentation, you can find yourself assuming that the member you're looking for does not exist, leading you in a wrong direction, and thus waisting more time.

If the behavior of intellisense is unpredictable, it kind of stands in your way more than it helps. And without intellisense, it makes no sense to use a bloated IDE for Python (or dynamic languages in general). Dynamic languages have simple APIs anyway that can be learned easily.

I have a shortcut defined for the "dir" and "help" commands in Python, and for "perldoc" in Perl, executed on the token under the cursor, and with the help of flymake-mode, it's more than enough. And in many instances it's even more productive ... if I don't remember the usage of DateTime::Format::Strptime in Perl I just look at the CPAN docs with perldoc, copy/pasting the example given.
