I would hope that engineering positions at financial companies require an interview process similar to that of Google's (although in practice my hunch is that they're not as strenuous, like you said), but my comment and the article aren't referring to engineering positions.

The simple truth is that people like the interviewee in the article just don't work on nearly as hard of problems as do Google engineers. Being an engineer myself, I've never had a finance job, but I've had plenty of friends and roommates who have. They need to know some math and have some Excel skills, but most of their time is spent on phone calls and Powerpoint decks. That's why even an easy first question in an interview for an engineering position (e.g. write a C function that reverses a string) is more difficult than the questions asked of these guys. Just look at the example of the most grueling question in the article. Describe the process of a leveraged buyout? That doesn't really require any analytical skills, creativity, or problem solving.

I really think it's suboptimal to have finance people running our businesses, Wall St., and our economy. In my experience, they have a hugely inflated sense of self-worth, which is based mostly on their hugely inflated salaries.
I must admit, with the world fiat economy slowly eating itself alive, too big to fail, massive TARP bailouts left right and center, entire middle eastern fiefdoms just saying "Hey sorry about that 60 billion IOU but we're going to have to put an indefinite hold on it".

Financial professionals whining about how much it takes to make the wheel turn in their industry strike me as about as honest and reality based as dressage shops for unicorns trying to make a case for why their particular brand of mastery ought to sit at the top of human endeavour.

No. And, also, the interpolated value yearlyadj isn't used. It's only referenced in commented out code.

I'd be interested in that too. I wonder if they include things like predictable levels of solar activity, volcano eruptions, weather cycles and the like to get this. Or, worse, it might even be stochastic or "random walk"-like which would make the variations meaningless (see diagram on http://en.wikipedia.org/wiki/Random_walk )..
I think the study is likely detecting "hybrids are disproportionately used in big cities and blue states", where pedestrian/bicycle traffic is disproportionately likely to be close to cars and thus gets hit more often (versus, say, rural Kansas where cars generally hit stationary objects or each other).

You would probably also find that hybrids strike proportionately more vegetarians than non-hybrid cars. This does not mean meat scares Priuses away.

That's a separate problem from adding accessibility for blind people. The obvious ways to make touchscreen phones easier for old people are larger buttons and text, and exaggerated visual cues, which help blind people not at all.
This is not the only data set that the warming trend is observable in.

[ In fact, some AGW skeptics don't deny a warming trend, but instead argue against human impact causing this warming trend (the A). ]

Nevertheless, here is what Real Climate says regarding the "hide the decline" bit (in more detail than their original post):

>>Declines” in the MXD record. This decline was hidden written up in Nature in 1998 (http://www.nature.com/nature/journal/v391/n6668/abs/391678a0...) where the authors suggested not using the post 1960 data. Their actual programs (in IDL script), unsurprisingly warn against using post 1960 data. Added: Note that the ‘hide the decline’ comment was made in 1999 – 10 years ago, and has no connection whatsoever to more recent instrumental records.

So, every climate record produced in recent years has no connection to this data. And there's lots of these.

Your evolution analogy is apt. Many (very smart) people would like to pretend this simply isn't happening or isn't possible.
Comments on the OP suggest it was cover art. Not sure what to make of that without more context.

Making it clear the data changed stops it being unethical, but I think the criticism of concatenating two data sources remains. Especially when the point of the graph is the sharp rise at the end - just as the data source changes. You really want to make sure the data sources correlate highly to make that kind of argument.
I would also expect hybrid cars to be used more in cities and less outside them, which could also add to a chance to hit someone, because there are more pedestrians in the cities. And so on. The conclusion should rather say, that there is no significant difference in this matter, as it isn't. (0.6 to 0.9…)
This sounds a lot like how my PhD oral qualifying exams went. Except I got 30 minutes of highly technical questions from all 6 committee members and then sat outside for 40 minutes while they deliberated if they should let me stay in graduate school (they did). After that I got to have two more personal interviews with more in-depth questioning. The whole ordeal lasted somewhere around 5 or 6 hours.
What does it create that isn't actually required?
Don't do #######

Don't ask for confirmation.

Solved.

(The ####### protects against someone peeking over their shoulder the exact instant they register, who wants to steal their password. It's not really very plausible and certainly not worth the hassle.)
The EU and the US have a lot of data sharing, mostly in one direction (EU to US). Indeed, you now have to register with the US (through the ESTA scheme) in advance so they have the opportunity to run background checks on you if they so wish.

I suspect you could get away with lying still right now as the system's so new, but I bet it won't be long before they'll be able to pull up British police records (if any) at the US immigration counter - or at least verify if you were ever arrested or not.
As someone who just successfully went through the Amazon interviewing process (new grad, 4 interviews on campus):

1) Relax. Maybe I got lucky, but all of the interviewers I met with were nice and pleasant. They made me feel comfortable.

2) Brush up on the fundamentals of CS. Pretty much all of the questions I was asked built upon standard CS knowledge. If you can pass a standard Algorithms/Data Structures course, the interview will probably be a piece of cake.

3) Think out loud. It helps more than sitting there in silence. As a benefit, the interviewer will most likely help guide you in the right direction.

4) Ask questions!

The interviews were actually a lot of fun! Good luck.
Having to type your password twice is a major cue that the action you're taking is to register a new account, not sign in to an existing one.

Some friction is necessary -- if you make it too easy the user won't be sure of what they're doing.

I don't know what ESR's politics looked like before, but he's been in deep teabagger territory for a while now. I would take anything he says on the subject of politics with… Well, I'd just not take it. He can pretend to be objective, but the use of winger slang (“AGW” and “MSM” are right-wing dog whistles in the same way as “Democrat party” or “socialism”) is a giveaway.

Here are some of his prognostications from the election last year. They're delightfully wingnutty, with a crunchy glibertarian shell:

“The Obama campaign smells of defeat”: http://esr.ibiblio.org/?p=449
“Democrats’ polling league in a generic contest has collapsed. Control of Congress is in play. Wow. Just wow. Considering how hard the Republicans have been fucking up and alienating their base, this is astonishing. EPIC FAIL.”

“Sarah Palin, American Centrist”: http://esr.ibiblio.org/?p=481
“So when I tell you that I think Sarah Palin’s religious position is pretty near dead center in the American spectrum, you can be pretty sure I’m not fudging to make that position look good.”

“The Obama campaign smells of defeat: II”: http://esr.ibiblio.org/?p=490
“The attempt to smear, discredit and delegitimize Palin has steadily become more intense and more damaging — to the Democrats.”

When it comes to politics, dude simply does not know what the fuck.
Combine this with JulianMorrison's suggestion (don't do the ####) & I think this a good approach.
Eh...I doubt you or I would understand the financial and legal considerations involved in taking a public company private. While I share your view about engineers not having enough power, you might want to consider that LBO deals and the like are basically 'financial engineering' and it's pretty technical...there's a lot more to it than the popular conception of 'take the CEO out for a round of golf, offer to double his pay if he recommends it to the shareholders, call up some rich people to throw in the capital and PROFIT'. The hardcore financial types I know work their asses off, have really good analytical skills, and know their calculus.
I get the feeling that you are either vastly undervaluing yourself or you don't have much to offer. Either is fine--but you should know which of the two applies best to you. You might still get an internship, but I'd argue if you give it some thought, you could get more bang for your buck(time and skills)!

1. Pretend that due to a constraint, you cannot offer your services for free

2. Ask yourself how much you can charge?

3. You'll likely find yourself asking what you'll be charging for. Note down the answers because they are your best skills.

4. If you want to do it for free, think about what you'd like to gain in return. Consider it like swapping salary for a new skill or two.

This is a simple process to jot down what you can contribute, what your skills may be worth, what you may be able to exchange your current skills for. As opposed to random crapshoot which will probably lead to a disappointing end--as most things do if you're not somewhat clear about your goals.

Good luck! I saw your tumblr and you definitely have insights you can apply to all kinds of work.
Well, the graph you link to doesn't include error bars or any other indication of uncertainty. Leaving out error margins and plotting only the mean is unfortunately common when presenting scientific results to general audiences; but that doesn't mean the actual scientists don't have the full data.

You're just attacking ESR's character. It's fallacious to discount his blog post just because you don't like his character. Please, can't we have a rational discussion on the topic?
Ouch! Ineed, it's a lousy benchmark; I only recommended it from memory because it blew me away the first time I saw it.

FWIW, if anybody can recommend a good benchmark, I would be happy to do a write up since I am proud of the regex performance of the other CL library (cl-ppcre.)
I needed to do pattern matching to pull data out of many different formats, then clean the data before processing it. We were parsing radio station song feeds, and the data is varied, chaotic and often unavailable. This was also a port of a perl POE app, and so it was regex intensive in its original implementation and I don't see how you could effectively deal with such noisy text without regexes.

As to snark - his reply was snark, I just replied in kind. Regexes are incredibly useful for all kinds of things, most especially in parsing data from web services. The fact that he didn't need them isn't 'funny,' it means we were doing different things.

In any case - using Erlang for something like this is so much win. The POE, and threaded implementations got real ugly real fast as we scaled it up. I knew Erlang could do it - across boxen, without a problem. It sounds like the regex libs have improved, and I look forward to using Erlang again in the future.

Happy? :D
Cool, I'll look again. Thanks.

I can't tell you how many times I've tried logging into HN using the signup form (which, of course, doesn't ask for your password confirmation). The password confirmation, I think, has become a necessary input field to let users instantly recognize and know that they're signing up for an account. Qwerty keyboards, for example, aren't the most efficient way to type, but the layout has become so ingrained into our brains that we can't imagine any other way to type.
No, what I’m doing is pointing out that his opinions are a) wrong and b) delivered with right-wing spin. As such, you should not take what he says about matters political at face value.
I dropped out of my PhD at MIT Chem Eng this year to run my startup full-time. Never looked back. I am also international, like the person in the story seems to be.

He just needs to try each one separately and see which one gets him more excited to go to work. It really is that simple.

To turn matter into biochar requires heat input - so generally this means burning some sort of fuel - which releases CO2. Leaving the matter as it is, or burying it does not require this fuel, hence the CO2 "savings" are even greater. To do all this to sequester carbon seems to be missing the point, and we'd all be better off by not burning anything in the first place.

Well, organic matter normally releases carbon when it decays, so just leaving it as-is would be carbon neutral, liberating the carbon the plant originally drew from the air to grow.

On the other hand, the pyrolysis process requires energy, yes, but releases very little carbon from the material being processed. The resulting carbon-rich biochar doesn't rot, so the carbon isn't released back into the atmosphere but remains in the soil, while new plants grow in place of the old ones, pulling more carbon from the air.

The claim in the article, presumably, is that the carbon output associated with the energy to heat the biomass is less than the amount of inert carbon added to the soil, making the entire process effectively remove carbon from the atmosphere.

Highly doubtful that the amount of carbon thus extracted would be significant, though. The soil improvement aspect is far more interesting to my mind, the carbon stuff is probably just a way to get more attention.
weird. i can access it on my machine. DNS propagation perhaps?
Dunno about PE firms, but the Google engineering interview was roughly comparable to my interview at Morgan Stanley. (The second was slightly rougher; one of the interviewers printed out the code they were currently debugging and asked me to find the bug.)
As someone who has done some experimental work, I can appreciate how emails like this sound bad but may actually not be.

With every set of data, there is a lot of additional information necessary for interpreting it. I'm sure that if someone is just given my raw data, for example, it is open to interpretation -- however, ALSO given the "metadata" (which is often in my lengthy, informal lab journal), the rationale behind my interpretation is more clear ...

If I had to explain every little nuance to amateurs and explain why their interpretations are incorrect, I would certainly not have much time left in my day!
There's also the possibility that hybrid drivers simply drive more often because their cost per mile is cheaper.
One option might be to not ask for a password at all and auto generate it. Most sign ups include some form of confirmation email, perhaps a password could be sent with it? Not appropriate for every app but registration with nothing more than email address is getting as stripped down as possible.

Yeah, use 1Password and let it generate a strong password and fill in the forms for you. Can't say it quite changed my life but it's been the most useful piece of software I've bought all year.
This seems to plague all employers in software.

See Paul Graham's essay about how the only way to spot a good hacker is to hack with them. Which puts all programmers in a lemon market.
Thanks for the criticism! I take your point about fructose and appetite.

My reason for believing that carbs stimulate the sympathetic nervous system is that I think that, paradoxically, excitement and stress are essentially the same thing. (Excitement initially feels better because thoughts are stimulated and negative emotions are numbed, along with the rest of the body.) Whatever, when it comes to blood sugar, hyper is followed by hypo, so you can get cortisol that way.

I doubt that looking at neurotransmitters is the right way to think about addiction. It is a mental phenomenon which operates on a different level of abstraction. To use an analogy from computing, explaining a software bug does not in general require looking at hardware.

Until we have good explanation of addiction, we can't meaningfully test related theories. So it's hard to take seriously what medical science currently regards as evidence in this matter. However, the fact that AA uses a 'spiritual' programme to break addiction, and that some addicts claim to have been helped by mystical experiences brought on by hallucinogens -- these do seem like significant pointers.

More basically, people commonly report being in two minds about food, which is the hallmark of addiction.

Ask HN: why aren't my comment votes registering?
When I upvote/downvote a comment, the score appears to go up/down, but if I reload the page, it has not changed (my votes on submissions are working).

Is there a new karma threshold for comment voting, of some kind, perhaps based on average karma (per comment)? Or is it a bug?
The feeling of Yawning on purpose is not the same as yawning spontaneously :)
Notes:

1. The fudge factor is flat after 1970. The hockey stick we care about is after 1980 or so, sharply increasing in the 1990s and 2000s.

2. The fudge corresponds to problems with recent tree-ring data that were discussed in previously published literature (I don't have the citation). The phrase "very artificial" almost certainly means it's a crude estimate based on some model that's simpler than the author would prefer -- hence, the flat line for recent values.

3. If this was an open-source project, you'd see a reference to the article that explains where the fudge came from, but it's not. Natural scientists tend to not really believe in software engineering, they just write a procedure and munge it until it works, leaving dead code and mysterious comments in their wake. (Source control? That sounds like fluffy industry stuff...) As JCG pointed out, yearlyadj isn't used in the copy of this script that we have, although it might have been used in an earlier draft of the script.

Of course, the most visible educated critic happens to be an urban Canadian liberal who favored Obama in the last US election.

The Republican/Democrat thing is just more stupid tribalism. It doesn't matter how good of an idea a Republican has, you'll never see an urban educated middle-class young person agreeing with them on the merits because the idea is from the wrong tribe.

So, I'm not really sure what you're trying to prove, other than to whip up tribal sentiments in favor of the misbehaving scientists (silicon valley is VERY blue country).
> ... it simply doesn't make sense...

It does if you bother to learn the language, rather than assuming that it's a pastiche of whatever features you bothered to osmose from a smörgåsbord of whichever other languages you might have encountered.

> It just doesn't "make sense".

The notion that a programming language both can and should be completely intuitive to novices who don't have to bother to learn an arbitrary list of syntax rules is absurd on its face.

Parentheses never create first-class lists in Perl. They only ever group expressions and disambiguate precedence.

Parentheses sometimes create first-class lists in Python and Ruby, for example. They also sometimes group expressions and disambiguate precedence. If you want an arbitrary set of rules to memorize, look at the languages which conflate various and orthogonal uses of the same punctuation character.

Ask HN: Advice for seed-stage startup funding firm in Banglore
HN Folks,

I am looking advice on how you think we can use the YC "secret sauce" to make our firm remarkable.

If you'd like to discuss this via email, I can be contacted at chiragchamoli@gmail.com

Basic Info: I am about to start a seed funding company which takes the Ycombinator framework and applies it to Indian Markets, as YC is not yet present in India. My firm will emphasize on Enterprise Software, Medical Research and Rural Innovations. I don't have a lot of money but I know how to do the startups right.
FreeBSD seems to make more sense to me than Solaris or OpenSolaris. I always have to go looking for HOWTOs on simple things. Plus, there is more available for it, and IMO it has a better community.

I don't know what ESR's politics looked like before

Before what? I don't remember there ever being a time when esr wasn't a deranged wingnut.
I don't see how this is the huge problem they make it out to be. Since when do people execute strings of random English text. It also isn't clear that they did anything besides search texts for runs of valid machine code characters so where is the complex engineering here?
Why kill it if people are upvoting it? This means many people here value the repost (and weren't aware of the first post).

In fact, I would argue reposting of old gems from HN time to time. It helps everyone here!
