I've just blown a technical interview. Not like this though.

I've got lots of experience, know my languages inside out and have several launched products to millions of people. I did every problem in the recommended book (CtCI) and know data structures and algorithms well. I wasn’t prepared for the nerves though.

I interviewed at a large social network recently. 3 out of the 5 onsites went amazingly well. 1 was okay and the last one totally tanked. It wasn’t a particularly hard question, but I didn’t crack it immediately so started to panic.

What made it 10x worse was that the interviewer sat in complete silence, not responding to any of my ideas. I followed all the recommended strategies: Throwing out a brute force solution, discussing what you are thinking (incidentally, I said the correct solution very early on!), trying different data structures - but he said nothing and checked his phone.

When I got the call, I was absolutely devastated. I had put 3 months of preparation into this and it was all gone in 30 minutes. The recruiter couldn’t believe it as he thought I was a shoe-in. I told him about the interviewer and he was furious. He said he would pass that on as feedback, but there was nothing he could do - they have to respect the process.

I appreciate the humility in this article. As much as I want to blame the interviewer, the process, how technical interviews are broken, how that company isn’t all that, etc etc - the most fruitful thing I can do is learn what went wrong and how I can overcome it next time.

In repairing my shattered self confidence, I’ve found this very helpful:

“Doing poorly on your Google interview could mean a couple things, if you're a good engineer….Which of the two evaluations is more meaningful?
A) A few hours with busy people who don't know you trying to guess how good you are, with only a few minutes of a problem they're familiar with as a probe.
B) Years of successful performance in your career.

A way of explaining it that (hopefully) makes it clearer:

Let's say you have just invented the concept of prison, and let's say 50% of people come back every year after going to prison for the first time, and 50% never come back again.

In year 2, you'd observe that of the year 1 population, 50% returned, and 50% didn't.

In year 2, you'd also add a new influx of prisoners.

Therefore, in year 3, you'd observe that of the year 2 population, 75% returned and 25% didn't.

But, the real underlying recidivism rate is still 50%, not 75%.
Can you expand on that? I'm curious how someone would use this technique to improve their coding.
I think you're mixing things up. One of those cases was "abuse of power" related (the one you're bringing up), and the other one (share sale described above) was tax related.
* The Vice story was older and listed an older rate (it went up to $85), I agree that under normal circumstances the re-publisher story should be deleted.

* I can't downvote.
Interesting. I do remember reading about this and the fact that at one of Google's building they have to use special air filters to filter the air due to where it was built.
Similarly on a motorcycle you're frequently told simply to look where you want to go as you enter a turn. That alone makes your hands do what they need to do.
Typically I advise people to use CTE's for ad hoc queries and to avoid CTE's for production code. CTE's are easily abused.
I had the weirdest let-down after an interview this summer. Like the author I thought it had gone fine but something entirely else was going on. The interviewer let me know the reason I was not chosen was that I used agressive micro-expressions and lacked diplomacy. I don't know if my love for technical excellence (a topic broached quite fully during the interview) or my anecdote of an anti-pattern at a previous employer was really presented with toxicity but my takeaway is that sometimes you have just been set up for failure and nothing can be done to salvage your chances.
No prob, if you need any help, drop a mail.
I'm not against what you're saying w.r.t it being a place to show code and interesting not-for-profit projects, but we can't force Show HN to be that and only that. Forcing an open-source only culture on Show HN is no better than startups/SV forcing a for-profit culture on Show HN. I think we're better off with an open place that's balanced and healthy.
How do monopolistic entities full of self-interested humans solve problems of externalities?

The economics research on public choice has done a great deal for setting aside the common yet inaccurate assumption that government agents pursue the interests of society. It's not appropriate to compare real world markets to utopian governments. Both are imperfect. The real question is which is superior under realistic assumptions.
If my comments are pointless arguing, so are Elon's.

Worse, Elon's are just factually incorrect (e.g. "The energy needed is the square, i.e. 9 units for space and 900 for orbit.") [and, yet, it remains, uncontested, at the top of this thread].

>It is, however, important to clear up the difference between "space" and "orbit", as described well by https://what-if.xkcd.com/58/

is a non-sequitor because no one seems to have confused space and orbit. Additionally, the comparable part of SpaceX's machines (the first stage of the Falcon 9) doesn't go into orbit (it is supposed to land not far from the launch site and does not loop around the Earth to do it).

What is the import of "orbit"? Elon is the one that brought the word into the conversation, not me.

>You are focusing on the word 'orbit' and not the overall meaning.

Then, please, what is the overall meaning of those tweets?
you forgot -> people show up in the thread and mock anyone who doesn't accept that RMS is, has always been, and will always be right about everything.
Virgin Atlantic have a great service where, upon booking an economy ticket, you can then bid for an upgrade. The person who bids highest, wins.

It's such a simple concept, but fantastic in that a higher priced seat that might have gone unsold, instead goes for what someone perceives its value to them to be.
The article talks about the benefits of the 'quiet eye' technique and says that it is a teachable skill, but I couldn't find much information on how to practice it in the references.

While looking for more information, I found these blog posts[1][2][3] on how to apply the technique to golf playing. Perhaps some of the instructions can be adapted to other activities as well.

Just a reminder about why people still use xp:, earlier versions of windows supported a real time mode (sort of like the preempt rt Linux patches). This is needed in order to run some equipment but later versions of windows (post xp) have dropped support for it.
> See other comments here, the plane was obviously only some seconds over Turkey and therefore already flying out of territory.

This was not an isolated incident, many incursions have occurred since Russia started its operations in Syria, and Turkey has warned, repeatedly, that if aerial incursions continued, it would result in planes being shot down. It seems to me Russia has been deliberately sending a message by the continued incursions, and that Turkey has responded to that message in exactly the way it said it would (and the only way possible other than accept that it will become a vassal of Russia.)
>(One funny thing about it is that it often really shows up CGI sequences, the comparative lack of noise apparently giving the interpolation more to work with than usual. The results can be either slightly comical or pleasingly eye-popping.)

I've noticed this with anime in particular. Even though none of it's hand drawn these days it isn't done like 3D CGI in movies. It is, for the most part, designed to look two dimensional. The motion smoothing makes it look like you're watching a 2D diorama or pop-up book where the different cells are sliding on top of each other. I kinda like it.
Companies "hack" their customers all the time but somehow it's unethical for customers to do the reverse? It seems to some people the "free market" means corporations can do whatever they want but not vice versa.
Regulations that make possible entrance to a market - standards, forced ineroperability, common carrier, dumb pipes etc - are generally good and provide more efficient market.

Regulations that prevent entrance to a market - by artificially rising the capital requirements to the impossible, are probably not helping the free market.

We always had the option of the "invisiclues" but... you had to order those and wait (time and money) or drive to a local computer store and buy (money). Both put a damper on the urge to "cheat".
The ATmegas only go up to 16KBytes RAM, with 4KBytes or less being usual. As a Harvard architecture device, none of your binary is memory-mapped, which can make porting existing code a bit annoying. sizeof(int)==2, which doesn't help either (however sizeof(void *)==2 as well, so there is at least that).

It's rather unusual by today's standards. Certainly quite different from an ARM.
Boring holes
How does Sourcegraph plan to enforce that Fair Source license? Do they rely on companies to self report?
There's a good chance that the same interview (same questions and answers) with another company would pass and be a 'great fit', since they were looking for different things etc, there's always the lottery aspect.
Would you like to expand on that?
A bunch of people I know who've carved out a little niche for themselves making wordpress sites for small businesses are justifably concerned that their skillset has been made obsolete.

IMHO, (and I'd never mention it to their face) they brought it on themselves.
It would be a breakthrough of Gaussian proportions!
> Changing IDEs isn't nothing, but it's not like I'd have to rewrite my code.

You'd have to rewrite any IDE code you've written, which isn't nothing (that pain is a good part of the reason why emacs is still stuck on elisp instead of Common Lisp).
Stealing Bearer Tokens with an Angular Expression Injection
I've heard enough stories of Russian planes violating other countries' airspace and not responding to warnings, that I immediately assumed a fairly deep incursion and Russia being clearly at fault, but crossing that tiny sliver of Turkish territory? Technically it's still a violation of airspace, but shooting it down is exceedingly harsh. The only possible conclusion is that Turkey was eager to shoot down a Russian plane.

Not shooting down a plane doesn't have to mean you tolerate airspace violations. You can still complain and stress that this is not okay without shooting anything.
> If you're never subject to frequent microaggression (of which you've just made in your reply), it can be hard to understand how significant they really are.

Anybody can be mobbed or subjected to unfair circumstances in the workplace.

While some take such critical offense to things on the micro level, there are thousands of men in the valley who sacrificed so much, tolerated unfair circumstances, and never opted to view themselves as the victim. They grew to be stronger people because of it.

It may come as a surprise, the feelings you're experiencing don't represent what me and my colleagues are seeing.
I saw this video where Bryan Cranston gives advice to young actors. He basically says, don't go into an audition 'looking' for a job, or 'wanting' a job. Go in, do your thing, portray the best you and get out. If they want you, you'll get the job, If they don't ... why would you want to work at a place where they don't want you ?

This was eye opening for me. Totally changed the way I went to interviews.

(Can't find the video now :( )
Sourcegraph CEO here. Unfortunately, GitHub makes this impossible. It's closed source and offers limited ways to integrate—primarily via external, rate-limited external API clients on their proprietary platform. It's too bad the most popular code platform is closed.

We believe developers deserve to have a hackable, extensible platform for their code, so it can be more deeply integrated with the best other dev tools. That's why we built Sourcegraph and released Sourcegraph's source code. It's also why we're making it easy to build deep integrations into Sourcegraph (see, e.g., https://src.sourcegraph.com/sourcegraph@master/.tree/platfor...).

That seems like an incredibly accurate description about what happened to you.
> There is no reuse and views are opaque and exist in a single namespace.

I'm not sure what you mean by "opaque"; they encapsulate logic, which is a plus.

On the "single namespace" thing, that sort of depends on the RDBMS; e.g., in postgres, within a single DB, one can have multiple schemas, and there is nothing stopping a view in one schema from referencing objects in another schema, so views for one database may exist in separate schemas, which act as namespaces. Other DBs offer equivalent functionality, though the names of structures may be different.
It's not attaining anywhere near orbital velocity, but it's still going pretty fast. All that speed has to be shed somehow, and they do that through atmospheric drag.

The deceleration is high because the atmosphere gets thick pretty quickly, so you end up losing all that speed quickly, which means a high acceleration.

They could use the rocket to slow down --- but to do that, they'd have to carry fuel up, which makes the whole thing much larger. It's vastly more efficient to let atmospheric drag do it for you for free.
And yet the tens of thousands of new investment properties in Sydney and Melbourne that sit empty while waiting for a capital gain – labelled “speculative vacancies” by non-profit lobby group Prosper Australia – or which are rented to tourists at highly inflated rates, indicate that the market is not always a panacea for affordability.

Is that not just a glut that hasn't yet taken hold? If there really is over-supply, the investors will eventually end up competing with each other once they try to realize their capital gain.

I don't mean to suggest that a growing glut of empty properties ending with a bust is the best way for this to go, but it does seem to me that on a long enough time scale, supply & demand principles will still hold true.
The Get Lamp documentary looks awesome. It's CC licensed so you can watch it for free, but they also have some physical DVD copies left with all the extras.
No, that is absolutely not a problem. If an interviewer is interested in your OSS contributions, hes's not going to be any less impressed because it's a project he's never heard of.

The simple fact that you have OSS on your resume makes you stand out. Period. I have seen exactly one resume with OSS on it in all the years I conducted interviews.

One.

Very true. But I contend that I did not portray the best me. And that is a valuable lesson. This essay is not about the job I didn't get, it's about the lesson I learned about myself.
Air travel in the US is highly regulated, but the market is actually very free. If you have sufficient capital you can absolutely start a new airline and be carrying paying passengers in under a year. In fact you could probably do it in a few months by leasing existing aircraft and contracting with existing aviation service companies for most operations. The FAA actively supports new ventures and will work with them on the approval process.
Someone else can provide the math, but if due to the tanks being mostly empty you can burn anything from practically 0 to 5 G thrust, intuitively you burn the least total fuel by flooring it to 5G at the last minute.

Consider the alternative of burning less than 1G of acceleration, you'll fail to slow down although you'll descent acceleration will be somewhat lower. At exactly 1 G it'll keep falling at a constant speed till it runs out of fuel, then impact.

Or if you're asking why performance is so much more spritely at the end of mission, unlike boats or cars the fuel in the tanks is like 95% of the mass of the rocket, so something that barely waddles off the launch pad with full tanks weighs practically nothing at landing when the tanks are nearly empty.

Governments did not came from outer space, nor are they form a separate magisterium that's unrelated to free market. It's something that naturally forms as society grows larger than few hundred members and the simple interpersonal methods of coordination and punishing defectors (like losing support of the whole clan if you cheat) stop working. The whole idea of separating government from market models seems strange to me.

Frankly, I fail to see how you can hold a working market in a big population without a somewhat monopolized government structure. If suddenly, say, the USGOV disappeared, leaving behind a libertarian utopia, I'm pretty sure it would quickly degenerate into acts of violence, an era of warlords and famine, after which people would probably figure out that a single entity enforcing some rules was generally not a bad idea.
Do the anti-GNU, anti-FOSS advocates of proprietary software ever see theirs? The facts presented in the submission are being largely dismissed without cause.
Well done! Looks like an awesome app :)
That would be amazing given that a (orbital) day on the ISS is about 90 minutes.
You dodged a bullet. Any interviewer who judges you based on "micro-expressions" would have been insufferable as a manager.
There are reasonable and intelligent criticisms of market institutions. This is not one of them.

Exactly what recourse would I have against someone who stole my sandwich? Unless I know the person or there is solid evidence to identify the individual, the costs of investigation and prosecution far exceed the value to be recouped. Police will take my information, file a report, and nothing else will happen.

Not only is that state not helpful under these conditions, but private institutions have often found solutions to similar problems before the government does. Look at Paypal. They faced very similar conditions of fighting fraud and theft that couldn't be remedied through legal means, so they developed many private forms of regulation which allowed online exchange to flourish.

Hidden city ticketing doesn't waste the airline's fuel. They'd burn just as much fuel if you used all segments you purchased. What wastes their fuel is stupid pricing that makes it cheaper to buy segments you don't want.

It's not generally considered unethical to, say, buy a bottle of wine just to dump it out. Why would the same thing be unethical when it's an airline ticket instead?

This is a legitimate comment.
I confirm that Windows 10 shows advertisements to install Office. They appear as small popups in the notification area of the toolbar. This was on a fresh upgrade of a Windows 8 machine.

In task manager I found a running program (which I can't recall the exact name of but the purpose was obvious) that was for posting ads to install Office. I searched for the name and found instructions for uninstalling it.

I don't know if there are others or not. I only ran Windows 10 for a few hours to check it out.
What we learned from scaling a product team
Time data could/should be randomized (can still be ordered, but distribute regularly over the day). Couple this with pushing commits at random times in a defined timezone and you probably can get rid of most time leaks?
They admit most of this is obvious, All of this might seem obvious—after all, “keep your eye on the ball” isn’t exactly a new idea, but then goes on to add that it’s only recently that scientists have had the technology to fully grasp the value of intense visual focus.

Also, apparently it's a difficult skill to master.

I'll try applying this to soccer shots in my game tonight :). (Demostration of effectiveness for penalty kicks: https://www.youtube.com/watch?v=UnXqmisYKpc)
None, I hope. They're bacterial breeding ground. Yuck.
Also super important in tennis. Your ability to direct and control the ball consistently dramatically changes if you always keep your eye on the ball. Of course, it's easier said than done to do this consistently.
"Insanity?" That's an ideological statement, but it doesn't really hold up to the facts, I think. It has always struck me that the gravamen of the Open Source movement has been to accelerate the improvement of important common libraries by enabling anyone to view and evolve source code, with the 'evolution' taking either the free or a commercial license. The simple fact is that, over the last few decades, there have been good and bad improvements under open licenses and good and bad improvements under commercial licenses. It's the possibility of improvement that is important.

I might go even further, and suggest that if one had to parcel the value created by open source software into two buckets, the one being value created by reason of transparent source code, and the other being value created by reason of no-cost source, the majority of the marginal value creation will have been because of the former, not the latter.
> Both are imperfect. The real question is which is superior under realistic assumptions.

And I'd say, why not both? It's obvious that the market is superior in many cases. It's also obvious that the government is superior in others. They both cover for each others' failures.
Making the tech market efficient
You don't need to sign up to use Meetifyr, it's all done via a unique url for each meet up (in fact there's no way to sign up).

For sure there are loads of alternatives, this hopefully strips it down to the basics. Think a semi-private, shared calendar amoungst friends.
> When talking with others, be aware of when they want to understand the specifics, and when they want to understand the general ideas.

I think this might be the wrong takeaway. In reality when people say they want specific examples then they want specific examples, and when they say they want general principles they also want specific examples.

If they ask for a general principle then maybe throw that in as the last sentence, but most people people simply aren't able to process abstract ideas, even if they think they're able to.
