It is not the presence of an internal heuristic that makes an algorithm greedy, it is the choosing of locally optimal solutions. For your claim to hold, you would need to demonstrate that people make locally optimal solutions, at least in the context of this problem.

That is most likely a wrong assumption. Greedy algorithms usually do not find globally optimal solutions, yet the people solving these problems are finding -the- solution. That is enough to suggest that the heuristic people are using is much more complex than merely choosing local optimums.

What's your typical use case for one of these? I've read the wiki page on PCR but I still don't see it.
"At YC," says Taggar, "Every round we have more applications. But we
only accept between 2.5 and 3.5 percent of those who apply. The first
round this year we had 44 companies; this round we have 64 companies
[almost a 50 percent increase]."

I haven't seen this number before (2.5-3.5%). If they accepted 2.5-3.5% when they accepted 44 companies, that's 1760-1257 applications. If they accepted 2.5-3.5% when they accepted 64 companies, that's 2560-1829 companies. So this comment gives us a range of between 1257-2560 applications.

Good luck everyone! :) I'm applying this winter.
Analysis: Facebook video chatting handy, definitely not "awesome"
The worker is your employee if you can control not only what work is done, but how it is done

That's the only sentence in there that actually defines what an employee is, and I fail to see how someone mowing your lawn fits the requirement of dictating "how work is to be done".

A guy who mows your yard every other week -- most likely along with a host of other yards in the area -- is most certainly not an employee. Sure, he could try to make a case if he were injured, but no normal-thinking human is going to interpret "provides occasional service" as "employee".

and when John is out of town and offers for his dead-beat friend Jacob to mow your lawn that week and you decline, then John is your employee.

Preferring the services of one person or company over another has absolutely nothing whatsoever to do with the definition of employee.
This is one of the coolest and most useful new companies I have seen. I love how I, uh, have no freaking clue what their technology stack is because their business doesn't depend on selling to other geeks. (Though that would of course be interesting.) Props!

Maybe it's your attitude?
It looks like you're implying anyone who doesn't get it is 'not-so-smart'. Even if you're not saying that explicitly they can probably sense that attitude :-)

I myself also don't see how it's a Facebook killer. I don't care about social networking, don't spend tons of time there, barely mange to check out my 'feed' sometimes.

If all my friends go there, sure, I'll tag along, why not? But am I going to make an actual effort, make a profile and even try to get my friends to join (as there will probably be none) all because of it having a new way of grouping people? No way.

I'm not saying it's not going to workout, it might or might not. Nobody knows at this point.
Just understand that most people don't care about something being a little better if they don't see how it's game changing for them. And let's be honest, for most of us google+ won't change much at all, for me the experience would be very similar on both sites.
So if somebody comes telling you how google+ is so different the natural reaction is to dismiss that person.
And also keep in mind that for some people Circles are a feature they would not want to see.

there are free web tools that can help you design unique primers.

True, but if you are going to your own PCR, you might as well do your own primer design. It's practically the "hello, world!" of bioinformatics, not to mention that a primer design server might not be able to help you if you're trying to do something fancy.
This is spot on. I was a "band geek", more specifically an "orchestra dork", in high school, and a computer science nerd as well. Not exactly the most popular combination. My attitude in high school was mostly not caring about being popular, and I didn't make any effort to identify with people I considered to be unlike me. I had other friends, in the music program, who were sociable and could identify with the less academic oriented crowd and they did fine. I gained a lot of this awareness in college and actually went on to be my fraternities social and rush chair, and what changed was that I gained a more acute awareness of people's social interactions and put in the time to figure out the college social situation. This isn't always a huge priority of nerds, or they just haven't gotten there yet: they may be so advanced in one aspect that the social skills haven't quite caught up yet. However, I disagree that all these geeks will go on to inherit the world: if they don't EVENTUALLY gain those social skills and recognize how valuable they are, they won't get anywhere near as far as they can. There is some ridiculous statistic like some 60-70% of all senators/presidents were Greek (frat and sorority life), and I think this speaks less to the value of the greek system and more to the fact that people who place value on interacting with other people and communicating go farther than those who don't.
Congrats Jeff, this looks awesome.
One of my students (CS) once took a creative writing class, and her professor, a man well-known in the creative writing community, told her he thought computer programmers make better writers. She was pretty sure this had a lot to do with understanding revision and outside input. When you write a program, the compiler (or possibly your unit tests) tells you "it's wrong! Fix it!" and doesn't always give a lot of guidance as to how, but you figure it out and come out the other side with a better product. A lot of the other students in the class took the critical comments of the professor (and peers) as almost personal attacks on their perfect creation.

All of which is to say that the Computer Science/Creative Writing benefits may go both ways.
I am sure you know this, but many jobs list on company career sites are not open. Many are quite old and dated.

Just like there are diminishing returns coding for many hours without resting, trying to build a business without having a social life will ultimately have damaging effects. Knowing how to communicate is half the battle and you're not going to learn how to do that sitting in front of a screen all day.

I think we've all read the stories of founders not sleeping for days and ruining their personal lives in the process and I just don't see how any of that is necessary.

Excellent point. The comment wasn't a slight against the author. Far from it, I wish I had a mind even 25% as analytical as his.
Water bottles are great. Way better than those absurdly overpriced bottles of water!

(Odd how one ordering of the two words seems to imply to me a sort of reusable bottle made of heavy plastic or metal while the other ordering implies those cheap plastic bottles of water that often times cost as much as the reusable ones anyway).
Facebook to build more data centers
I just was able to invite 2 family members, 2 friends, and several people who posted on my blog asking me how to get invites. I am out of invites now. I invited people who I thought would really use it.

BTW, a little off topic, but I have blasted Google on several occasions about dropping Google Wave. Turns out I complained for nothing: the latest Wave In A Box (WIAB) code drop is open source, builds easily, real time sync between users works very well, and the web UI is similar to the original but simpler (in a good way).

From the wikipedia article [1]
"PCR is used to amplify a specific region of a DNA strand (the DNA target). Most PCR methods typically amplify DNA fragments of up to ~10 kilo base pairs (kb), although some techniques allow for amplification of fragments up to 40 kb in size.[5]"

What that means is this: you have a sample of some DNA or protein. Typically it might be only one copy or only a handful of copies. Nothing in bioscience works on tiny copies; you typically need thousands or millions, particularly for operations like dna sequencing. PCR allows you to amplify -- ie copy -- your sample by causing the DNA helix to split from heat, including a polymerase or enzyme that does the replication work, including spare dna bases, then cooling to cause the helixes to reform. It's essentially a doubling operation; you run k heating/splitting/replication/cooling cycles and at the end hopefully have (#{ starting copies }) * 2^k

Doing the previous operation requires a pcr device which very accurately and evenly heats and cools a microtitre plate; the polymerase; something to dump all this into like very clean water; and raw dna base pairs.

And of course, it would be naive to discount the advantage Google has through the presence of one person and one person alone; Andy Hertzfeld. He's a big hitter... a really big hitter. To me, it feels like Yoda just turned up to show the young upstarts what it really means to be a Jedi.

Not to play the doubter, but I remember when Hertzfeld was slated to be the savior of Linux back in 2000/2001 (god I feel old!). His company, Eazel, did produce the file manager Nautilus, but then promptly went out of business.

Dropbox is my absolute favorite YC company by far. This appears to be their biggest weakness to date.

They've done a piss poor job of having a public voice. They don't respond to things quickly and when they do they're somewhat defensive and dismissive.

The truth is most of the noise actually is bullshit. They know that. The problem is public perception isn't fair. You can't ignore false hysteria and expect it to go away. People will form opinions based on headlines alone.

They need to humanize the company. Make sure everyone knows Dropbox is run by good people who have good intentions. More Google, less Microsoft.

They still have a ton of momentum, but it's all based on word of mouth. If they lose the warm fuzzy feeling people have about them they will suffer badly in the long term.

Sometimes following the links from the shared items (if they weren't public) will allow you to create a profile and sometimes it won't. The invite button and interface was up for a very short time and is already gone again so the shared links method is likely the only way to get in at the moment.

Hey Google+ folks!

As I bet you've noticed, we are facing pretty incredible demand for Google+ invites.

As Engineering Director of Google+, I wanted to take a moment to explain why we're growing the system slowly. First, we want to make sure our infrastructure scales so the service remains fast and reliable. Second, we want to ensure that bugs are fixed while there are still a relatively few people in the field trial.

Things are going well with the systems right now so we feel comfortable enough to open up invites for a brief period. Our goal is to double the user base in the field trial. (Sorry, we're not giving details about how many folks are in the field trial yet).

So, in a few minutes, we'll open up invites again.

We continue to throttle invites, so please don't mass invite folks as it won't work. If you invite a handful of your most important friends and family you're much more likely to get these folks into our system.

Thanks again for providing so much wonderful feedback!
+1 to the meetup issue. Thankfully, most meetups in NYC are in Manhattan or near-Brooklyn. Most times it'll be a 30 minute passive commuting commitment anywhere you go, so it's definitely better than bay area.

Starting up: The first two hires
I'm not sure how they plan to stick to this part "we won’t share your content with others, including law enforcement, for any purpose unless you direct us to".

If Dropbox gets a sub-poena to hand over some user's content, can they really ask the user first whether they can share it with law enforcement? I was involved with some of this stuff back at MSFT and it isn't something you had a great deal of leeway with.
> Strangely, there were Christians on both sides of the issue

I wonder if that's why I wrote: "Yes, some religions advocated and supported slavery"

The existence of religious slavery supporters does not refute the claim was that religious people ended slavery.

As I put it the first time: "[the religious supporters of slavery] lost to [religious opponents]."

You die a hero or you live long enough to see yourself become the villain.

Facebook, Google, Microsoft...all were everybody's favorite scrappy insurgents at one point.

Once perception shifts the other way, it's hard to turn things around because everyone starts assuming the worst. This incident is a perfect example: the old ToS were standard boilerplate that appears in a bunch of other places, and had most other companies done it, it would have been seen as a non-issue. However, since Dropbox has been receiving other negative press lately (some centering around real issues, some centering around similarly trivial nonsense), that changes how every new story about them is perceived.
I'm glad to hear that Wave is doing well. I thought about grabbing it and trying it just to see how it was doing and maybe contributing, but just never had the time. It makes me happy that it has a real chance of survival.
We had mandatory code reviews at a previous job. We had a grab someone and have them look at the code in our cube pre-checkin. I found that is was great for finding non-obvious bugs.

For example, our codebase was for a legacy system and there was a lot of knowledge and experience about the code that was never seen without talking to someone that had already dealt with it. So it was not uncommon to have comments about a call being really bad in a loop cause it caused an unexpected database query, or to use weak reference objects here, other such things.

I miss the way code reviews transferred institutional knowledge.

Also, I learned a lot of Eclipse shortcuts through these code reviews.

Lisp (and lisps) appeals to Platonists (as you can see in this article): they are minimal and pure.

Gosu is not pure nor particularly minimal: it's rooted in the historical experience of Java software development, for better and for worse. As such, it is more of an Aristotelean language: practical, derived from experience and not particularly concerned with unification.

I enjoy both languages, but I'm an Aristotle guy.
