Profit is the primary objective of a company. Gross revenue is only interesting if there is reason to believe that more of it can be turned into profit, expanding margins.

Companies can be valued after many criteria: innovation, market share, revenue, leadership etc. But the value of all of them is in their potential for generating future profits.

The other fundamental method for valuation is to look at the balance sheet and value the company by net assets.

>Contemptuous comments about bajillion-dollar valuations and hype don't provide any value to this discussion.

The OP asked why the stock was down, and whether this was a buying opportunity. I offered perspective that it might not be, based on the analysis of someone respected in the field. I understand that DCF models can produce any numbers you wish (as does Prof. Damordaran; says so right in the article). But there's his model and there's his numbers, based mainly off assumptions that Tesla builds cars.

Tell me, what value did your comment add to the discussion?

If I sound "contemptuous", it's because the hype and fandom is tiring. Read the comments in this thread ("Tesla <3") or on Prof. Damodaran's article ("You can't vaue Tesla unless you've driven one!").

> It is beyond me why such law exists in first place. People from Mexico can jump over the fence come to US and work while the president goes out of his way to ensure that these people can get US taxpayer's money but my wife who is engineering graduate with over 8 years of experience working for American companies in India can not work in US because it takes away jobs of American people!

You just answered your own question. The people "jumping the fence" (as you put it) are often taking low-paying (even below minimum wage) jobs that US citizens don't want, so it's less problematic politically[0].

On the other hand, there are a lot of citizens who would love whatever job your wife would get with 8 years of engineering experience, so it's more politically challenging to give that job to a non-citizen, even if she is undeniably qualified for it.

[0] In fact, some industries rely on illegal immigrants and/or illegal migrant workers as sources of labor below minimum wage (see: agriculture[1]), so they have an incentive to enable this practice (or at least turn a blind eye), since they can't rely on the legal resources to provide them labor at that price.

>many ISP forbid you to send e-mail at all (they close port 25).

Can anyone name an ISP that forbids their customers from using SMTP to send mail?

My guess is that the person I'm quoting is confused by the longstanding spam-control measure in which the ISP requires the outgoing mail to go through a mail server designated by (and usually run by) the ISP rather than going directly to the recipient's mail server.

But if I'm wrong about that, I want to know!

Because investors have no clue how to value growth companies, because interest rates are low and because some prominent growth companies with no profits have been on a non-stop* share price rampage for 14 years. The revenue multiple pricing of Amazon, Facebook, Twitter et.al. is cargo cult finance. No one really knows how much these companies will eventually earn, so some commentators have come up with a plausible after-the-fact metric that sounds good in a soundbite.

A company is worth the present-value adjusted sum of all its future earnings, and that is it. How to guess, discount and risk-adjust this number is a different question.

Not sure it's as profound to others as it was for me, but my biggest lesson in negotiation was the idea of negotiating in bulk. If, say, there are 20 points to work through, the idea is to know before the negotiation starts which of them you're going to insist on, which you're willing to barter for, and which you're ok to lose (i.e. barter with).

As opposed to fighting through each of the 20 items one by one...
It is possible to coax that codegen out of clang. The trick is that you need the high half of the product, so you must use a larger type, in this case __uint128_t:

uint64_t div10(uint64_t y) {
const uint64_t magic = 0xCCCCCCCCCCCCCCCDULL;
__uint128_t prod = magic * (__uint128_t)y;
return (uint64_t)(prod >> (64 + 3));
}

See http://libdivide.com for how to get this codegen with runtime constants (I am the author).

slowing sales in the US. They are also slow to deliver their lower priced car which may be moot by the time they do with all the offerings coming down the pipe from established players.

The industry does not simply sit and wait for innovation, they don't bet the farm on one technology, they spread the risk across multiple engine solutions. Until battery technology gives us very fast recharge, average range, and longevity, range extender and hybrids will rule the roost.
I see this more as lack of direction rather than burn-out.

Burn-out, in my mind, is something very different.
Hstore, and the supplied functions for converting to/from records has been very useful for making a "one size fits all" history table.

Currently I'm working with numeric range types to model order quantities and stock quantities, and forecasting which order is going to consume what stock by joining on rows with overlapping ranges, then taking the intersections of those overlaps. Again, Postgres supplies functions and operators for range overlaps, intersections, etc.

In the absence of those datatypes, there'd be a lot more work required to achieve either of these.
Good points, but wish the author pointed to the enormous, readable lit. (Few people I know have read things like "Getting to Yes.".)

People often are ideologically blind to fundamental antagonisms in various relationships. (For example, market interactions is a big one.) I've had entirely good deals with people who've tried to (if you'll excuse my language) fuck me over, by silently changing little things in PDF contracts, benefiting on the X% of people not paranoid enough to run diffs.

Some argue, "How can you make a good deal with someone who just tried screwing you over?" Frankly, most deals are that way. Landlords try to; you buy products from companies who routinely lie to you (and even try to make you feel miserable about yourself); etc. And if you're a bit privileged, you may be lucky enough to be able to hit back hard at some of these people.
Why aren't they getting a lot of use? Is it because they're new or ORMs don't have them yet? (Note: This might sound like a false dichotomy but these are the only 2 reasons I know so feel free to add more reasons.)

Well, this is implied, since if the price were based on Q1 2014 earnings the shares would be worth precisely zero.

This is exactly what people on reddit used to say about reddit six or seven years ago. I have to believe the decline in general quality, and the quality of the front page most of all, in reddit could happen in some form to HN, without vigilance on the part of users and mods.
Uh, price-to-sales is pretty rare. "PE" or price-to-earnings is much more common. But a high growth company will likely prioritize growth over profits so PE not important.

Hstore is definitely an odd one in that it's an extension so sort of core, sort of not. Other's its likely just that people default to what the ORM does. Hstore actually sees 13% usage across production databases on Heroku, so while something I'd still consider it much lower than what it probably should be.
Nicely encapsulated doesn't have to imply a black-box implementation, though. I for one would like it if compilers were less black-boxy; ideally, I want to find out why my compiler does a particular thing by investigating its output, querying the API, going through the compilation steps, etc., rather than having to google some StackOverflow answer.
So the name makes sense?

I'm definitely not your target market here, if i'm devoting time to TV i'm focussed on enjoying that, alone or with the people in the room.
Well that already shows a stack trace. it's not mentioned here because it's not a new feature.
The problem with that design is that in a lot of use cases, images don't necessarily need to be 'referenced'. For example, I'm using docker for a build/test system; we spin up a container from an image, run some stuff in it for a few seconds, and then shut it down. 90% of the time, the images are 'unreferenced'.

The other suggestion, put forward by a docker dev in another comment, is to have a clean command for unnamed/untagged images. Our build system has 'buildbot' (python package compilation) and 'software' (test environment) images, so this sort of automated cleaning would get rid of all of that extra crap that we have lying around.

The big issue for me is stacks of changes. Like git, anything you commit, remove something from, then commit again still takes up that space forever until you consolidate down. Which you can't do automatically.

Ask HN: Do Tesla and others have plans to use the expiring NiMH battery patents?
The efficient NiMH battery patents that Chevron has held hostage for almost 20 years are expiring this year[0], but I have yet to read any information about any companies jumping on the technology.

One guy[1] claims that his Toyota EV has run over 100,000 miles on the original set of batteries to this day, which is very impressive. I don't remember where, but I recall reading an article that stated that although Tesla's batteries perform well, they require the use of a very complicated thermal management system. Additionally, they're using Lithium Ion, whose longevity is questionable.

Some information on the NiMH patents: https://en.wikipedia.org/wiki/Patent_encumbrance_of_large_automotive_NiMH_batteries#Current_status_of_the_Ovonics_battery_technology

Does anyone know of what plans there are to use these, and how they can be utilized in modern electronics? Can Tesla somehow incorporate them in their cars?

The headline says that it is a stand against the FCC, but the substance of the article is that the coalition is promoting the value of the open internet without endorsing any specific policy. The FCC is also arguing for the value of the open internet, and preparing specific policy designed to support that.

What the letter actually takes a stand against is rumors that the FCC chair has already both denied and said would be bad policy about the content of the proposal that is under discussion.

So, Google, Amazon, and Microsoft are standing "against" the FCC by taking the same stance that the FCC Chair has taken, in opposition to a stance that it was rumored that the FCC Chair was taking.

Morgan Stanley's latest DCF arrived at $320/share, Goldman Sachs's arrived at $200, for instance. If your goal was to contribute by providing a contrarian view, that is fair enough and I might have misread the tone of your comment.

Idea: browser extension that notices two things: when you follow links from the HN front page, and whether you upvote that story. If you read an article and don't upvote it, it labels that article "dreck". If you do upvote it, it labels that article non-"dreck". Maybe it has some subtle reminder that you should remember to upvote the article once you're done.

People who use this extension make HN better for themselves (because they're classifying articles according to their tastes as they go along) and they're also making HN better for others (by incentivizing people to upvote good material when they may otherwise have not upvoted).

If you have enough HN karma to downvote, maybe only downvotes count as dreck. Then you're still improving both your own and others' experience.

Yo dawg, I heard you like HN, so I proposed a browser extension that lets you improve HN while you improve HN.

You're right about knowing where you stand on each item going into the negotiation. It's important to point out, however, that savvy corporate negotiators will insist on stepping through one item at a time, taking a strong position on most and offering up only a token gesture or two in order to disguise their true interests, build leverage and the appearance of good faith.
It's a real PITA that the first thing you do when you start experimenting with docker is to have to find out about this missing clean command and to design a custom alias to fit your needs. In my case, I was expecting it (eg. `bower cache clean`, `npm cache clean`). Regarding the unclear intent, that's what cli help is for! `docker clean` could output it by default.

Given that any realistic DCF model of Tesla needs to be probabilistic to some degree (measure different scenarios against each other) and that a company's true market value is still the unknown present-value adjusted sum of all its future earnings, we are still going to see massive disagreement about Tesla's correct valuation in the years ahead. Contemptuous comments about bajillion-dollar valuations and hype don't provide any value to this discussion.

This sentiment is mis-placed. Markets don't "argue" over prices. And DCF's don't set valuations based on measured anything.

The DCF is there to simply inform the prejudices of market partcipants. The utility of DCfs is simply to get some insight into people's predudices. This is arguably more helpful than simply pretending that any single set of prejudices is more or less {correct, useful, interesting}.
Percentage-wise, that's a pretty significant improvement, but I need more than an 0.2s performance increase to justify the switch. Are there technical reasons to switch to btrfs instead?
