"Get it": No, I am saying that in asking about linear programming and dynamic programming as in Skiena, Google is not "prepared" and, really, is dealing in nonsense. If want someone to know some optimization and have a good reason for this, then fine. Then, cover some good material on optimization. But evaluating people on trivia about optimization as in Skiena is silly and arrogant, uninformed, dysfunctional, destructive, etc. It's something from the Queen in Alice in Wonderland:

"They didn't review Skiena? They don't know dynamic programming? Then, off with their heads!".

At the level of Skiena, f'get about optimization.

Again, Google is showing that they are far too centered on 'computer science' where they accept low quality material just because it was hijacked from its real origins in various fields of applied mathematics into a book on 'computer science' and poorly presented there.

For the network simplex algorithm, about the most elementary case is the transportation problem where find a least cost way to ship widgets from several factories to several warehouses. Then generalize to a network. Then, a simplex algorithm linear programming basis is just a spanning tree in the network. To add a variable to the basis, add an arc from the network. Then the spanning tree will be converted to a network with a circuit. Then run flow around that circuit in the direction that reduces cost until the flow on some arc hits zero. Remove that arc from the basis and again have a spanning tree. Cunningham's work guarantees to avoid cycles and tends to be faster.

But, if Google calls you, don't mention such things if you want a job! Instead, just mumble on about how great C++ is!

"Oh, I have Stroustrup under my pillow!"

Also mention some other buzz words.

Google has become arrogant, inwardly directed, and process-oriented. The history of companies that do that is not good.
Presumably it could if you factor in coal's carbon externalities.
Note that Tim most likely refered to actual physical aggression, something which is arguably worse than making "edgy" presentations (the article there mentioned OSCON: http://lwn.net/Articles/417952/).
The rules are similar, and a bit more generous if you're female, or above a certain age. As for the other part of that statement, you'd be surprised at how many people in that bracket can speak English - at least well enough to use a cell phone :)
http://www.topchan.tv was just released about 2 months ago and have never made a dime. The hosting is for free for now so the net is $0. But I have never really wanted to charge for it. It's more for building for myself, and see if others find it useful.
My best guess for where the $112 million is going is not for cashing out but for rapidly expanding abroad where they're seeing clones rise quickly and gain traction (Wimdu, 9flats). I expect to see a few small acquisitions to build out more inventory in Asia (East Asia + Australia) and probably South America. Congrats to the team on their success over the last year, I recommend AirBnB to my friends all the time.
I'm all about anti-harassment guidelines, but the following is just as offensive as harassment:

I’d like to borrow a line from the Flickr Community Guidelines, which use the term Creepiness as follows: "You know that guy. Don’t be that guy." If we hear that you are that guy, we will investigate, and you may be asked to leave.

That's not a clear guideline, and it's sexist, to boot. Consider:

We all know that prudish woman. Don't be that prudish woman.

That wouldn't fly, and for the same very good reasons that their guidelines need more work. They need first to remove the gender language, since unwanted advances and inappropriate behavior can come from either side, and second to spell out clearly what is prohibited, since that is the only way the rules can be fairly applied.
It's pretty unlikely, but fun to think that they might be planning on pulling something similar to the Chrysler Building.

Every. Single. One. But I don't care!
I find it unlikely that a company would reduce shareholders via an employee buyback. Employees arent likely to, and may not be allowed to, sell all of their stock. Also, the employees will become shareholders again if they have unvested shares waiting in the wings.

It's also very standard for a growing company to switch to Restricted Stock Units as an employee incentive, holders of which do not count towards the magic 500.
I hope their rules will apply to both men and women. There is sometimes a tendency to overlook when women harass men.
I was given a preference sheet to fill out after receiving an offer, and I was given my first choice, also. It seems there is quite a bit of leeway to change teams if one finds something else more interesting.
Perhaps. If the French school hadn't tried to use quantum mechanics in completely bizarre ways, leading many people to label them as wankers and thereby staining the entire profession, I might agree. The fact that the French view still persists 50 years later doesn't give me confidence.
Well, no, I didn't use scare quotes, though that was my intent. Usually it seems like the more people review some procedure, the more they convince themselves that is how it's done.

Oh sorry, I'm wasn't intentionally arguing against being pseudonymous. I was thinking of ways to manage the mutability, multi-mapped and non-uniqueness of common names behind the scenes. If circles can be kept separate, you could have a single login containing different circles for your pseudonyms. As an aside, I hate how current FB and G+ policy turns us non-celebrities into second class citizens. Disgusting.

Thanks to nradov above for info on HL7. Surely these major international orgs should already have been aware of it?
I tried a bit of this just a moment ago. Came up with the answer to a problem I've been thinking about for some time now. Additionally I thought of some great ideas for weekend projects.

I'm suitably impressed to keep trying it out to see what else I can do with it, if not to experiment a little - it is very much like monkeys at typewriters.

Anyone else feel this is like "intellectual improv"?

Honestly though, why compete just to show off? There its making money as the tallest structure, here it will be completely isolated, nobody comes here, whoopteedoo.

FWIW, I built something like this for myself years ago because I needed to know when my ip changed. I locked it down so I'd be the only one able to use it. When I first saw jsonip.com, I kicked myself.

The brilliance of jsonip.com isn't really the service, it's the vision that it should be free and world-readable.

Frankly, the discussion below turns quickly into bickering, but in response to your question, in my limited experience I think you've hit the nail on the head in terms of the size of the community, though I think that has more to do with the prominence of 37 signals etc and less to do with any technical superiority.

I personally prefer Django for a number of reasons though I've also been impressed by RoR in my dabbling. active record's migrations are nice, and the ease with which rails let's you write dynamically changing forms and various other niceness is really great.

Technical questions aside, I think RoR is the default web framework. At general hacker type meet-ups like Startup Weekend, Rails is pretty much the default framework to work in as more people are familiar with it.

Django is wonderfully well structured and literally just about anything can be accomplished elegantly by subclassing this or that. As you said, the difficulty comes in figuring out what and how to fill in those gaps, which more often than not includes heavy use of grep and browsing around the Django source.

I think you'll be fine with whichever you choose. Learning new languages and frameworks is enjoyable, so try some rails and see how you like it. Smart people and great projects have been done with both.
The feature that people confuse with anonymity is that everyone can create a wallet and join the network. No need to sign up or provide personal information. Hence the myth.

When careful enough, bitcoin can be used anonymously. But the developers do not claim that it's anonymous by default, certainly not in the current mainline client. For example, the wiki page about anonymity:

https://en.bitcoin.it/wiki/Anonymity

Anonymity is not guaranteed. There are various initiatives under way to improve this. But people should stop thinking that anonymity is the single redeeming feature of bitcoin, anyway.

>You could simplify it and say that it went like this: Egypt, Greece, Rome and Europe.

Not necessarily. The first big European civilization was the [Cucuteni-Trypillian culture](http://en.wikipedia.org/wiki/Cucuteni-Trypillian_culture) which developed north-west of the Black Sea and was quite ahead of what was developing in the Middle East or elsewhere at the time (they had better pottery, barter tokens, biggest settlements in the World - up to 15000 people-, and were possibly the authors of the first writing system, 1000 years before the Summerians).
OLEDs and LEDs however still don't have a CRI that matches that of a nice incandescent light.

There is much to-do in the theater world about when LED light sources will be able to take over the venerable HPL and other tungsten sources, and the ability to accurately light color is a major stopping point.

The post put too much emphasis on one book, Skiena. E.g., I had never heard of it.

Better would be just to have a list of topics. In that list, my view is that dynamic programming should not be one of the topics.

Google is looking for silly excuses to reject people and/or really just has a silly view of what is important.

I made Idyllic Past[1], a webapp that emails you a weekly comment from your Hacker News and Reddit accounts. The eventual goal was to catalog all the things the user liked on the internet and present random items to him by email.

I was hoping to capitalize on nostalgia by running ads in the emails.

Unfortunately, I got only 3 signups. The post I made on HN was completely ignored (only about 20 people visited the link), and the post I made on Reddit ended up with a net score of 0.

Oh well, lesson learned -- gauge interest on a proof of concept before spending the time to build a full product.

This is kind of interesting. Where does your thoughts come from? If I asked you to think of a famous person, and say the first person that comes to your mind, what determines whom you will think of? Presumably you were not thinking of a person before I asked. Did you have any choice in what person you started thinking about?

Maybe some feminists see it as payback for thousands of years

The people pushing for a change in dynamics and acceptable behavior in male dominated conferences or social situations that they find oppressive or threatening are not doing it as a form of payback, I can assure you that.
Not necessarily. Depends on directional facing. A south facing spur up the mountain may provide no shade at all to the base.

And longer, yes, but not in need of vertical support.
I expected something more lush, along the lines of 37 Signals' offices, or perhaps Twitter or Google's bases. The photos give me the impression of a spartan and somewhat uninviting place, somewhat like unfinished versions of various areas in Half Life.

Every interview process sucks. I interviewed and got a job at a company that modeled their hiring on Google's asking me puzzle type questions. I can do really good with those. Doesn't say a thing about my coding skills. I feel sorry for the companies that model their process on Google's, especially the small startups because you need the exceptional engineers that fall through such cracks to really boost your business.

It's not so much the rationale of this interview process, reading the response from other Googlers seems to show that this selection process does a good job of maintaining a cultural fit for those that make the cut. The problem is that it seems to make enemies of people without a hardcore technical background when a simple review of their background would help both sides from pain.
The topics that are just computer science are not very good, and the topics that are good are not really computer science and are covered poorly in the book.

You know that after reading only the table of contents?

One way and another, for nearly all the topics in that book, I've worked much more deeply with the topics from other sources.

You worked much more deeply the topics in a book that you didn't read or even see? And that's an argument for what? What relevance this has to anything?

E.g., there is just one, short section on linear programming. Gee, that's part of optimization! I've worked in linear, non-linear, linear integer, multi-objective, quadratic, network linear, and dynamic programming! I've published peer-reviewed original research in non-linear programming.

Good for you, I guess. Again, what relevance this has to the discussion? Because you did research you now want everyone to spend at least a year learning optimization? You want all books to cover only advanced optimization and not the basic stuff? You want Google to hire only people who took a graduate-level optimization course? Doesn't make much sense.

It's hard to read this combination of arrogance, self-promotion and name-dropping, which in the end hardly adds up anything to the discussion.

Also, the book by Skienna isn't the "official Google knowledge base", it is just a book people recommend because it happens to be an easy way to prepare for this certain kind of interview, I guess it started with Steve Yegge recommending it on his blog for this purpose. I don't understand what's at all the purpose of discussing its contents, when it doesn't have any relevance to the topic. From what I understand they simply ask you some basic algorithm questions at Google and I guess that's pretty natural.
The most exciting claim to me was how efficient and robust this method of harnessing solar was. In particular:

- "Because it works on temperature differential, not absolute temperature, it works in any weather"

- "Because the heat of the day warms the ground up so much, it continues working at night"

- "It requires virtually no maintenance - apart from a bit of turbine servicing now and then, the tower "just works" once it's going, and lasts as long as its structure stays standing"

If these claims are true, then it would make sense for this plant to have a much higher capacity factor than most solar plants given that the major factors lowering CF is mitigated in this design (works at night and no shutdown for maintenance). Maybe I'm stuck in CS land where we think by factors of 10 but the numbers in this article doesn't seem too far off the beaten path.
So as long as someone is a 'rockstar' coder, it doesn't matter if he/she destroys the morale for the rest of your employees?

I'm no expert in American patents so forgive me if I don't fully understand things, my country doesn't even have software patents :O

But it seems from my readings that applying a reasonable expiry date to them would solve so many issues.

So say an assumption would apply that after say 5-10 years a technology would be common place and hence no longer unique, and that a company that couldn't capitalise after that period shouldn't be able to be in a position to hold up an economy.
I had half-coded an apartment manager for landlords for e.g. collecting rents, doing maintenance, and the like, prior to realizing a) Paypal fees were untenable for rent collection, b) I wasn't going to get into a regulated industry while part-time, and c) I had no way to sell into the space. So I shot that idea in the head prior to launch. (I still use the domain for an HTTP proxy.)

Then later I started work on WidgetBakery. You know widgets, those lovely little embeddable Javascript/etc code pieces that you create so other people can promote your website for you? I thought it would be cool if you could do that without being able to program, so that e.g. a laundromat or plumber could have their own widgets, thus getting them qualified traffic and improving their SEO. I did not talk to any laundromats or plumbers prior to coding it, naturally. When I finally started talking to people after half-building it, I realized that all of my customers were going to be black hat SEOs in seedy industries (payday loans and the like), and that it was highly likely Big Daddy G would nuke my site from orbit within a matter of weeks or months from launch.

So, that's a few months of dev time and a few thousand dollars of investment (VPSes, designer time, etc) that I won't get back.

Appointment Reminder also has been lagging expectations, but I still have hopes (and better, a plan) for that one. Sadly, immigration issues are a bit of a tax on my time/focus this month. (Severity: Deportation bugs tend to get worked on first, what can I say...)
This is the most interesting point made so far. Agreed, I had not considered the likes of FSI. That does come with the issue of being painful reading XML config from app.config files, but can easily be handled via what we have.

Would you consider this to be out of the question:

open CorrugatedIron.Comms

let cluster = RiakCluster.CreateFromConfig("section", "path/to/file.config")
let client = cluster.CreateClient()
So you get the downside of being public but not the upside.
