Ask HN: When do you green light tech positions with management?
Quick backstory:

I applied for a Senior role with a medium-ish company and after 3 interviews and 3 successful code tests they said they thought I'd be a great fit and wanted to make me an offer.

A week goes by and I get the standard "we decided not to pursue this any further" email with no explanation. I emailed back and after a quick phone call discovered they wanted to hire me, but senior management was looking for a much more "junior hybrid role".

A quick meeting with senior management at the beginning would have avoided wasting my time of going through all those interviews and code tests.

So my big questions:

So is this normal practice? All but hire first THEN ask if the company even needs it?
Do I really need to ask at the first interview if they've green lit this need with senior management?

Thanks for any feedback!

While I didn't particularly like it as a student, looking back on university ~15 years later, the educational component that I feel like I got the most out of was being forced to take a variety of sundry non-major classes. Most of the major material I probably would have learned on my own anyway; it was the other 'breadth' classes that, well, broadened my thinking in ways I did not expect.

Though from a purely vocational standpoint, the elimination of the breadth classes would seemingly allow for not only faster graduation, but also taking more major classes. That may well be a good thing too.
Ah, the favorite of all favorites: the "taxes (or, any government regulations involving income) are theft" argument!

Following this line of thinking... is it "stealing" when schools are built, police stations are funded, or sanitation workers are paid to pick up trash? Starting from your point of view will likely not get far in a discussion that begins with "rent controls".
You're treating it as binary - compliant or not compliant. But laws are tested in court. These companies claim to be compliant, but we don't know because UK tax authorities avoid court for all bit the most flamboyant evaders. No case law means we don't know if they're complying with law or not.

Ask yourself - If you are making minimum plus x and they raise the minimum to your salary mark, do you consider your worth to be "the minimum" or would you prefer your wage rise in tune with the increase?

My guess is the latter.

The argument against minimum wage increases is that it has a ripple effect and raises other wages as well.
As someone who is writing a real-time 3d engine, let me tell you the experience is incredibly rewarding. My math background is weak, but the practical applications of 3d maths that you will learn is invaluable.

Answer: It raises prices for everyone, because the vast majority of companies will not simply absorb the hit to profitability, assuming they even have the ability to absorb a cost increase that large at all.
I see. So one might get fired, and maybe even sued, but it's not a matter for the SEC.
I agree that Melkor's narrative is essentially the same as Lucifer's: God created the world, and fathered a quantity of powerful and benevolent beings to watch over it... until one of them goes rogue, eventually becoming their Evil counterpart. But if Tom Bombadil pre-dates even the Valar, then he doesn't really fit into that Biblical narrative. He's definitely not "God". There already is a God (Eru/Iluvatar), and he's utterly absent from world affairs after the Creation.

We all "know" that Lucifer was an angel who disagreed with God (or some such), who then banished him from Heaven... But do we really know that? The Bible doesn't actually say much on the topic. All we know is that he was once in Heaven, and was cast out. We don't know if Lucifer was born there (as opposed to merely visiting) or if he was even an angel at all!

Most of us believe the Serpent and Satan to be one and the same... but the Bible never says this. It's entirely possible that they are two separate entities, with different explanations. If Melkor is the Serpent (who corrupted the Elves), then perhaps Bombadil is the real original evil. Possibly even the one who corrupted Melkor in the first place?

The Bible, much like Tolkein's mythos, has many inconsistencies + leaves a TON to speculation. That's half the fun (if not most of it) :-P

Bugs also were relatively high maintenance. Few would care for that these days.

Russ Cox said this year that generics aren't left out because of political reasons or design choice. They are left out because of technical constraints which are:

- Generics in current form won't work across the board with all parts of Go.

- Generics of form that will work for Go across the board are not technically trivial.

Honestly, I appreciate Go's philosophy of not implementing until fully understood and accepted. Besides, Go's primary design principle is that of composability. So you're using reflection in one form or another. Achieving generic behaviour with interface and reflection is much more consistent than generics as we know from other languages.
Ask HN: Working as part of an interview, for free?
I recently applied to a startup for a development position. I was told I would do a "trial interview" which was really just a feature implementation they needed. I was sent an NDA which also talked of when to invoice and had "rate: TBD" which i put in my rate next to. the spec was large, and I wasn't expected to do all of it, but I implemented the core of it, which was nontrivial; it took me over 25 hours to implement.

Now, I just talked with the boss today, and he said I wouldn't be paid for that time; that's part of the interview, he says. But I sank more than half my work week into this, and thought this was just a 1099 until i may or may not go on full time, because i was delivering a business feature and not just doing an arbitrary test.

Anyway, what should I do? I'm not so worried if I get the job, but if I don't then I feel like I've been cheated.
Before Uber, I never took taxis. Now I use Uber 7-10 times per week.

That's just one anecdote, but my business wouldn't be counted as Uber taking part of the taxi market.

It must be particularly difficult to relate to those of us that don't have that disorder. When the patient in the article described his leg as foreign, or that his "soul doesn't extend into that part" of his leg, my first thought was that surely amputees would feel similarly about their prosthetics, but by all reports a good prosthetic has a positive effect on those amputees.

Maybe they feel more like the limb is a parasite? If I imagine that I had a large parasite permanently attached to my body, I could begin to understand the desperation to have it removed.

It is just very sloppy fact checking. They wanted to write the story about how Uber is the fastest growing company ever (which it very well might be), but they care much more about the headline than the facts. Again: this is one of the most successful companies of all time in terms of growth, and the tech press is still exaggerating it.

This is why you shouldn't compare yourself to the myths of other startup's success that are being written about by the press.
While I do have problems with Uber's valuation for other reasons, this isn't it. Uber tends to massively increase the market for taxis. Loads of people I know who would never take 'normal' taxis now use Uber. Even teenagers use Uber regularly, they would never hail a black/yellow cab on the street (in my eyes).
Whether you support a minimum wage increase or not, to think that it won't affect other people than those that are getting the increase just isn't true. Here's some possible side effects.

- Prices of products or services increase to compensate for the increase in salary.

- Higher paid employees don't get raises since the money that was previously allocated for that is being used to pay for the minimum wage increase. (This seems to be happening in this case, where more experienced workers received little to no increase in compensation).

- Other benefits are removed or reduced to cover the additional cost (health insurance, vacation, sick leave, etc)

- The company can no longer be profitable with the additional costs and reduces the size of their workforce or shuts down completely.

Which of these side effects (if any) occur, depends on the company and its current profits, management and/or investors, as well as how much they are already paying employees.

If you look at the map, China is attempting to claim ownership of said straights.

Your second point is accurate, but China having the ability to disrupt a route brings it up to par with other powers, whereas right now they are solely at the mercy of foreign nations wrt other waterways, with no ability to respond in kind. This gives them that ability.
Just one year ago, a NYU finance professor calculated Uber's risk-adjusted value to be 5.9 Billion. (http://fivethirtyeight.com/features/uber-isnt-worth-17-billi...). I wonder what he would say now...
The first UberCab website appears in Archive.org at March of 2010 -- They might be ever-so-slightly older than 5 years, but it doesn't seem too misleading to call them a 5-year old company.

Their Delaware date of incorporation is actually 7/2010.
I won't argue the valuation is correct, but Uber can grow the taxi market. I take cabs much much much more often than I otherwise would have.

Before uber I'd spend maybe 200 bucks a years on cabs. Now I take on almost daily.

Also 1 billion for 2% of Uber doesn't necessarily mean it's worth 50 billion because there might be liquidation preferences.

Can you cite some evidence for this? My guess is that it breaks down much more on a coastal/inland basis than a liberal/conservative one.
Looking at it as it is, this can seem ridiculous. But, considering their domestic and international expansion it really isn't. Uber can pretty much replace cabs worldwide. When Uber has its driver API service fleshed out, you can expect tons of companies to be able to tap into that and essentially get anything delivered beyond Uber Eats.

what is the deep difference between this mechanism and a simple spring / coil?
Back in that time period? Sure.

The problems are a result of the political will shifting and the funding disappearing.
Uber's revenue numbers are awful. "According to Bloomberg, Uber had revenue of $415 million (we assume net revenue after payments to drivers, not gross revenue) and an operating loss of $470 million." That's for 2014, and it's leaked data. But it's not good. Why are they losing money? They're an app and a server farm, some "driver centers", and an admin staff. It's not like Amazon, with giant warehouses full of expensive inventory. They're already scaled out; the expansion phase is over.

You're absolutely correct; I quoted a gross oversimplification of the theory. It's more to do with per generation than actual old people, and people are always protective of home value.

Consider, however, that when an elderly person dies their assets,in this case houses, are usually sold off, which might be enough for a builder. It's not the core tenant of my argument, but it's something I'd never thought of before.
I'm consistently surprised at how often I hear about hacky, poorly engineered solutions in Apple products (and those are only the ones that are externally visible/relevant to product quality directly). I can't imagine they don't have access to broadly the same quality of engineer as other big companies, which leaves the question of why presumably deliberate product choices were made this way.
Thank you for pointing this out.

I think the argument leading up to that conclusion is also interesting:

"Whether disclosure is a breach of duty therefore depends in large part on the purpose of the disclosure. This standard was identified by the SEC itself in Cady, Roberts: a purpose of the securities laws was to eliminate 'use of inside information for personal advantage.' 40 S.E. C., at 912, n. 15. See n. 10, supra. Thus, the test is whether the insider personally will benefit, directly or indirectly, from his disclosure. Absent some personal gain, there has been no breach of duty to stockholders." [1] (My emphasis.)

Surely the 'thus' is unjustified here, given that the quote from the SEC is a purpose of the laws, not the purpose; some other purpose of the law might establish additional tests for a breach of duty. Furthermore, the quote from the SEC does not limit the purpose of the law to situations where the leaker is the beneficiary, yet that is claimed to be part of the conclusion that follows from it.

For completeness, I will point out that the next sentence says "And absent a breach by the insider, there is no derivative breach." This cannot be used to establish that no breach has occurred, because it is predicated on that assumption.

Claiming that rent control alone "produced" the "Bronx is burning" is a bit like saying that "pouring water on the ground will cause a plant to grow" -- you've ignored the steps needed to get there. Just like farming, there are many steps: tilling the earth, burying the seed, giving it water and fertilizer. Redlining, white flight, drug epidemics and shoddy building codes and enforcement all contributed to urban decay in the Bronx in the 1970s.
iTunes Match would acoustically match songs, and then if the match failed, would just upload the song to iCloud as-is.

I imagine maybe this behavior is intended to replace uploading the song if the song doesn't match? It'd explain the situation in the quoted tweet where a live Phish show got replaced by a live recording, assuming that it failed to acoustically match and iTunes resorted to a metadata-based search instead.

Aswath literally wrote the book on corporate finance. The valuation was done mainly viewing Uber through the lens of a taxi replacement. I think his caveat at the end explains away the pessimism;

This framework lends itself easily to other narratives.
For instance, one of the more optimistic takes says that
Uber is in the logistics market, i.e. it’s a player in any
business that involves moving people or things from
one point to another. That would lead you to define
Uber’s market more broadly and come up with a much
higher valuation.
Isn't the word 'array' quite obvious that it will create an array? Since PHP 5.4 you actually have the shorthand "[]" version available but it is still obvious to anyone who is using PHP or JavaScript (though JS arrays aren't hash maps like PHP's -- you need an object for that).

But I agree, it's crystal clear for anyone with a minor PHP knowledge. For the rest it's just "clear". (It will still work calling $a['1'] with the quotes so what exactly is the issue? If you mean the drawbacks of type coercion not sure if this example is the best one.)
Uber is best positioned to usher in self-driving cars. If they are successful at it, their market opportunity is much larger than the Taxi-cab industry.

They're losing money because they are aggressively expanding into new markets.

They're an app and a server farm, some "driver centers", and an admin staff.

And, you know, a lot of cars and drivers. Of course Uber would want to make sure we all remember they are not Uber property and employees, but they still have to spend a lot of money to get them on board.

Based on his way of assessing value Twitter is worthless. It has no profit. I think the real value in Uber is in how it has become so beloved by customers who hated using cabs. I know it's heavily impacted the way I drive. Living in Chicago I hated dealing with cabs, it made more sense to pay a slight premium to drive my own car and park in a garage. Now I can literally jump into an uber and be somewhere in minutes with a better experience and for less than a cab would cost me. That's awesome! That's powerful. That's going to change the entire transportation industry. Cabs are just the beginning.

Armour: side-effects-free JavaScript
I think they're still expanding into new markets, and they gin both the supply side (boosting drivers' wages) and the demand side (giving drivers discounts) to establish themselves in each new place.

I still don't get how that gets them to $50B.
There are a lot of commonly used mobile libraries that are larger than this. Some of them (e.g., JQuery Mobile, which weighs in at several megs) make this look tiny by comparison.

By that logic my car is powered by steel, because that's what keeps the fuel-air mixture sufficiently close together.
Uber's revenue will continue to skyrocket. They are not "scaled out," and as revenue exceeds well-beyond $1B and they no longer have solid investment opportunities for growth, their expenses will get in line.
They're spending money to get new drivers as they expand all over the world.
