Getting further afield, water's density actually changes considerably with a change in temperature.
http://en.wikipedia.org/wiki/Properties_of_water#Density_of_...

I'm not sure how common this is but I know Lake Michigan goes through an annual cycle where the water alternately mixes and segregates (by temperature). In the summer, the warm, less dense water rises to the top and stays there. In the winter, very cold water is actually lighter than slightly warmer water and a similar stratification happens. In spring and autumn the water temperatures near the surface equalize with water deeper in the lake and much if not all of the lake water circulates ("turns over").

They certainly aren't English speakers. It's a pity because they've a really solid product, just not showing it off well to an international audience. The rest isn't full of mistakes as much as just being informal and inconsistent, I suppose it's quite a difficult language if you're not accustomed to writing it.
I think you are confused by what 'value' is. 'Estimated worth', as you put it, is value.

There are many ways of attempting to value a company, including looking at the discounted (and estimated) future cash flows, but they do not tell the full story.

For example, as an avid skier, I might be willing to pay $1000 for a better pair of skis as I will get more out of the ski. A beginner skier would see no increase in utility in my skis over a $200 pair. So, what's the value of the expensive pair of skis? Well, to me it's at least $1000. To the beginner, it's no more than $200.

The same holds true for companies. DCFs and multiples are useful hints at understanding the value of a company, but ultimately, they are insufficient. Companies can see strategic value in acquisitions differently, including the value of shutting it down (either because of concerns of competition or to acqui-hire the team).

On the public market, shares will more closely represent a discounted cash flow view of the future, but not always. The author's point about different share classes is also valid on public markets where control does not always go to common shareholders. That said, it's extremely hard to fool the market, as you've suggested. There's a ton of data to confirm that the market is exceptionally good at pricing the value (probability weighted against tons of factors) of future cash flows based on all current market information. There is a ton of data to support this, and very little to dispel it.

it looks like most "deep" platforms listed in the wiki link are ~400m, so this would be 7.2m (assuming the compressibility factor is linear).

either way it doesn't matter for this argument. we're talking about the difference between water and whatever it's replaced with such as "nothing" or something cheap and abundant with similar properties.

also, the water we're talking about is not itself 4 km deep. it may be under 4km of sea water, but the fresh water under the seafloor may be only 500m deep with an equivalent pressure of 4 - 4.5 km.

Why the University of Waterloo churns out poker stars
Isn't this exactly how location is always done without GPS? Look at the strengths of all the radio signals we can see, and match against known locations? Admittedly it's previously been primarily cell-towers & wi-fi, not GPS signal strength, and I thought most of the previous data had been collected by people that also had GPS, not via foursquare checkins...

If not, why does my Android phone ask me to turn on wi-fi to enhance location information?

Edit: To answer my own question, the Android source code for this used to be available. At the time, they passed the visible wi-fi SSIDs and the cell-tower IDs, but not the signal strength (they had it in both cases). Not sure why they didn't pass the strength. Maybe it made caching really hard; maybe it sufficed just to pass them in order; maybe it didn't make a big enough difference... http://www.netmite.com/android/mydroid/frameworks/base/locat...

To me, this actually raises more questions. It's so surprising to me that Google don't pass the signal strengths ("everyone knows" that is how triangulation works), that I'm thinking the real secret is that the signal strength isn't actually helpful. In other words, I'd bet Google tried what FourSquare have discovered, and rejected it. Or it's patented :-)
Well to be fair, we released the same Bitcoin functionality for Android and Mobile Web at the same time. This was in May earlier this year (at Bitcoin 2013 in San Jose).

Sorry if my point wasn't clear.

>> This makes its estimation implicitly data-starved, because with a DCF at leat you are getting a time series of independent measurements.

It isn't a data-starved number. It is often as simple as DCF calculation of value - the book value. DCF isn't used to calculate book value. Book value is simply the sum of the tangible parts.
Not really surprising, but how do we stop it? Can it be stopped, or is corruption in government, just something we're forced to live with forever?
That's a circular argument, you can't appeal to clauses in that license to determine if that license is valid. If they can withdraw the license then that clause is also withdrawn.

I don't know about copyright law but in contract law just because something is written in a contract doesn't make it automatically applicable.

An analogous situation may apply here where this can be considered a misapplication and so the license does not apply.

Either way I'd not use this licence to comply with "don't be a dick". Not being an ass here may encourage future releases, being an ass over this could lead to "this is why we can't have nice things.".

I probably wouldn't, my service is around 12Mbit, it is fast enough for me and I've rarely saturated it. I fully understand that (like CPUs and memory) the tech will grow to fill the space provided. You claimed a 1-10Mbit/second data connection was fast enough but essentially made the argument from the standpoint of a single user of that connection. Home connections are often multi-user so by your calculations they are not fast enough for most users.

The Guardian is not your average newspaper. Take a read:

These ultra-high value financing rounds are exits for founders though. Not for all of their stock, sure, but if your company is worth 1B+, you don't need to sell all that much to get a security blanket. So founders are doing these rounds not because it makes their personal fortune seem large, but because it actually allows them to get a mini-fortune (and presumably they think it is good for the company). This happened very publicly with snapchat [1], and I'm sure it happened to many of the other companies listed in the article.

This article also makes it seem like the difference in value between common stock and preferred stock is larger than it is. When a company is small and very high risk, the difference between the common and preferred is extremely large. But as the company value goes up, this gap shrinks by quite a bit, because generally companies with 1B+ valuations have a risk profile closer to a public company than an early startup.

That argument seems rather incorrectly biased. The gist is "C++ is awesome, and if you have any problems, it's because you're not awesome enough".

Tim Sweeny's talk[1] indicates that a majority of their bugs are due to low-level "unsafe" code issues. If the people writing Unreal have those problems, I think it's safe to say that it's a problem with the language. Unless you want to make the argument that Epic doesn't hired "talent and experienced" pilots.

C++ sure has places where it might be needed, but those places are growing less every day. And it's more due to the momentum, not the inherent merits of C++. If, say, Microsoft threw their weight behind a language like, say, Rust, the landscape could change. Or if they really pushed on the CLR to make the type system encompass more things and really beef up codegen, we might get somewhere. (The CLR can already easily slide into low level code, even hand-written assembly; the general codegen and limited memory management options are what kills.) Instead, we'll see more things grafted on to C++ (like recent type inference and lambdas) that make C++ somewhat less painful and further reduce the pressure to switch.

> Come on, while there are plenty reckless police officers, there also plenty of reckless cyclists

The standard is slightly higher when you are a police officer. For example, I don't think I've ever seen police cars follow at a safe distance. It's clearly a foreseeable outcome that if the car in front needs to brake hard there will be a collision, yet people would say it is an unfortunate accident if they happen to hit the car in front of them.

Driving your car under control means exactly that. Give bikers a wide berth. Slow down if it is unsafe to pass. Stop tailgating. Slow down in general.
That's fair and I agree. When we near the point where we're throwing out perfectly good candidates in favour of female candidates strictly because of gender, then we have another problem.

We should work towards being more fair individuals and looking at both genders with the same criteria in mind, gender aside while also tapping into female development resources like the one you mentioned.

I also believe we should introduce tech at an earlier age, say in high school, because right now tech is grossly misrepresented versus the other sciences which women have no problem going into.
I live in the Minneapolis area and it's the same story here. I actually stopped riding at night because of it. And to top it off we're supposed to have the most "bike friendly" city but apparently nobody told the cops.

I have dozens of stories where bikers have been hit and badly injured by cops not slowing down at intersections, trying to get around cars and driving in the bike lane and hitting bikers.
I did have that thought in mind, but was more thinking about how people get upset with their government today (or their neighbors, or anything else they find annoying), but are unable to move to one they like better because they're tied to their house, children's school, etc. But if they can take their house with them, and homeschool with a MOOC, then things become a lot more interesting.

If people are able to move house (all of it but the yard) with 3-4 tractor trailer trucks, things become much more fluid and state & local governments will have to adopt more citizen-friendly policies, or suffer a brain/revenue drain.

Sort of like how Detroit lost almost 60% of it's population because they drove people away with corruption and bad policies. Only now it wouldn't take 70 years to happen.

A lot of charities have serious problems building and maintaining websites, and will be very grateful for any help you can offer. I would recommend reaching out to them directly about this, since they often don't even know who to ask.

In my experience with a few charities whose websites I've been brought in to rescue, they're often left in disarray after they hired a well meaning but inexperienced developer who they were introduced to through personal connections. This works well initially, but becomes costly to maintain - both in terms of financial cost and managerial time spent overseeing the project.

If you can commit to either a monthly check-in to keep the website fresh, or to helping them build a more sustainable workflow so that they can easily update their own content, that could have a huge ROI for them in terms of fundraising, finding volunteers, and, perhaps most importantly, reaching the people who need their help.

As it relates to homelessness, many homeless people have access to the internet via a mobile device or library. For these people, an intuitive website can be the best way to connect with charities and receive their aid. Many charities still don't have responsive sites, so they're essentially cut off from reaching the mobile population. I think the ROI on that alone would be a great place to start.

Show HN: Que, a Ruby-PostgreSQL job queue with ~20x the throughput of DelayedJob
Hi everyone - I wrote a job queue called Que, which uses Postgres' advisory locks to manage jobs very efficiently. My goal is to make it easy to cover jobs with the same ACID guarantees as the rest of your data. It won't be as fast as a dedicated or Redis-backed queue, but I expect it will be fast enough for many use-cases.

https://github.com/chanks/que

The 20x figure comes from a benchmark I ran on an AWS c3.8xlarge instance - this number will change depending on your hardware. The code for the benchmark (and some more detailed results) is here:

I am not constantly enraged at TWC. They charge way too much for what I get, but it works consistently at the advertised speed. The installer added a coaxial port for me in the room I wanted without complaining or charging extra, and my external IP has been static for three years now. I have never seen evidence of a cap (not that I am a heavy bandwidth user).

I still feel like I am charged way too much for what I get, and I'm scared to mess with anything (for example, to buy my own modem to avoid the ridiculous modem rental fee they tacked on) because I don't want stuff to stop working (or to have to deal with their tech support line). I am in no way happy with them. But I am not enraged.

(When I lived in Blacksburg, VA there were three options for broadband -- DSL, cable, and a university-affiliated provider -- which were all in heavy competition to be the most horrible. I was actively enraged pretty much constantly over the miserable state of affairs. So I know that feel.)

It is worth pointing out that this is only relevant if 1) they have the rights to it in the first place, which is not a given, and 2) a judge finds that someone trying to take advantage of the error is in the right, which is certainly not a given depending on jurisdiction - a long list of considerations might affect whether you could safely depend on the original license.

In this case it appears the copyright to the fonts is held by Commercial Type / Schartzco Inc., not The Guardian, and so they quite possibly don't have the authority to put them under the Apache license in the first place, making the license moot.

This is a recurring talking point, but it's not entirely accurate.

So while your statement is correct, it implies a relationship that doesn't actually exist.
