Presumably a yellow liquid is far less conspicuous than a shiny metallic liquid, and both acids are commonly stocked. I think it's easy to forget that obtaining chemicals on short notice was not always easy (especially not in a country that's just been invaded).
I've looked at this recently and just created a hn account to respond. GPS satellites broadcast their position by transmitting ephemeris parameters. You can compare the accuracy of these parameters with post-processed, high accuracy orbits from igs.org. For the last few months, the real-time ephemeris has had an RMS error of about 0.5 meters (95 percentile is about 1.3 meters). (This is the range error, which includes both satellite position error and satellite clock error)

Of course, these errors cancel out if you're doing differential GPS techniques. (Where all that matters is accuracy relative to the base station)

One thing that would be nice is to access IGS's real-time streaming orbit data over the internet and have the phone's GNSS chipset use that instead of the broadcast ephemeris. However, you might still want dGPS for single frequency receivers to help with ionospheric error.
We use combination of many different techniques incorporated into our SDK, so there is no one specific formula - think more about it as a "driver" for the physical-location and communication device (e.g. iPhone).

The major role is played by beacons. Since we manufacture them we have a full control of the entire physics behind the signal propagation. You can read more here about it: http://blog.estimote.com/post/106913675010/how-do-beacons-wo...

Once you calibrate your room you can make it a public room and other could build apps on top of it.
Use a box that matches the production environment for each specific project.

When possible I use boxcutter released boxes, as they generally have good support for providers besides virtual box.

So e.g. on new projects, I use one of the boxcutter Debian boxes, but for a client I have with a legacy environment, I'm using a centos box.
> The entire economic system is built around people trying to get the best deal possible for themselves ...

Getting the best deal possible is one factor, but it's not the only one, it's not dogma, and it doesn't justify bad behavior.

I think your post is a simplified approach to a complex world. For example, it assumes that the marketplace is free and fair, which it clearly is not. The powerful often use their power to prevent competition, or even to write the rules (via influence in government) of the 'free' competition. Also, profiting from others' suffering is wrong.

Finally, our economic system, while good relative to most in human history, could be greatly improved. Let's not allow a dogmatic idea that it is ideal stop us from getting better. For one thing, it could be made more free and more fair.

> it's not Uber or anyone else's job or responsibility to guarantee anyone or anybody a certain standard of living.

I strongly disagree. We all have responsibilities to our communities and society; if people didn't meet those responsibilities, the communities and society would fall apart. Those who don't do their part are parasites on those who do, in my humble opinion.
This is very high value, well presented, and I went to read some of your other work.

I appreciate your source cites. Well done.

Gold Star for never discounting without a reason. The amount of lost value due to this is insane. It is a constant issue I face. Most of the time, I find improving value perception to be the better, more sustainable answer to sluggish sales.
It very much depends on the number of people and obstacles (glass, metal).

The best approach would be to put more beacons in that "interfering" areas.

If beacons are installed high enough, so there is always a line-of-sight between beacon and phone it should work fine in the crowded space.
So Uber came to give them an option beyond "starve to death"? Seems like they should be praised even more.
There are a couple of companies trying to do this right now. Digit just raised 11mm to do something similar. Acorns does something similar with investing.

Welcome. HN is a good place.
Though to be honest, I think anti-discrimination laws are even more broken. One reason being that price fixing has to involve multiple companies, where anti-discrimination laws can involve just one company even if there are plenty of other jobs that the employee could choose from.
I know the arguments behind it, and I know the research shows it brings slightly higher conversions, but I always see charm pricing (e.g. 2.99 vs 3.00) as an insult of sorts to my intelligence.

It's like the company is saying they don't think their customers have the mental capacity to reason that 9.99 is effectively the same price as 10.

It's even doubly meaningless for some products in Australia, because with 5c being the lowest coin in circulation purchasing a single item worth $9.99 will be rounded up to $10 anyway.

Unfortunately with antitrust lawsuits, they usually happen too late to stop the damage from being done, as we're seeing in this case and as we've seen with Microsoft and IE.

The way this could be solved without "abusing" antitrust power too much is by looking for "anticompetitive behavior" before companies actually get 90%+ market share in a market. At that point it's obviously too late, and with heavy lobbying-influenced politicians and institutions today, the punishment is unlikely to fit the crime, too, and the monopolists will only get a slap on the wrist and get to keep their monopoly (which makes the crime all worth it).

Example of anticompetitive behavior: Microsoft not allowing other browsers to be installed on the Windows mobile platform. It doesn't matter Windows mobile only has 3% market share. Why wait until they get 90% market share (again) to do anything about that awful and anticompetitive policy?

Same goes with Apple which doesn't allow other companies to compete with its "core apps". Why would you ever let something like that happen? It should be quashed from moment zero. Not to mention Apple already has a very strong position in the mobile market (especially in the US), but that should be beside the point.
What I always wonder is, what is market dominance worth?

Intel has $50B/year in revenue, net income of $10B/year. So they paid about one month's profit as a penalty for strategies that helped them dominate the market for years.

Which makes me wonder if anti-competitive practices start to look, even in spite of possible litigation, financially prudent.
What about if everything is in private repositories?

Apart from that it's pretty sexy.
> "they do not use a password hashing function"

From the weave crypto docs at http://weaveworks.github.io/weave/how-it-works.html#crypto:

"The public key from the remote peer is combined with the private key for the local peer in the usual Diffie-Hellman way, resulting in both peers arriving at the same shared key. To this is appended the supplied password, and the result is hashed through SHA256, to form the final ephemeral session key."

After trying to make use of Homebrew for a couple of years, I've given up. I refuse to install it now.

Using a combination of Vagrant for project environments, and a generic Debian VM (which could also be handled by vagrant but has much less need for it) for miscellaneous stuff, I am not missing brew.

The other advantage to this approach is your mac will likely remain stable and fast for much longer. Running a web server and a database server and an app server and who knows what else constantly (and by default, at startup) can make for a lot of RAM usage and ridiculously slow startup/logins.

Move that shit all into VMs, and keep your host as simple as possible. Sure, run your IDE, editor, debugger, what have you, but you should be able to quickly and easily just stop everything related to any given project/app.

Edit:

Also, and I know this will probably not be a popular opinion around here:

Whenever possible I use Mac App Store versions of apps. After a couple of clean-installs since the inception of the MAS, I am absolutely in favour of this approach. I can generally queue up all my MAS sourced apps for download + install quicker than I can open site, download, install & add license details for probably ONE app from outside the MAS. I know it has limitations and some apps will likely never be available in it, but those that are, are so much simpler to re-install on a clean OS.
There is no reason at all why this information has to result in more for less.

Couple better value perception (and that's a great topic for Nick to do sometime in the future) with effective pricing and now you have them paying more for more and happy about it.

Even better, adding more value means adding more to the price too. Built in race to the bottom avoidance, while actually delivering great value, not diluted value at higher prices.

How this plays out depends on who is pricing and what their overall strategy is.

I think he also may have gotten caught in the trap of early success.

If you view projects as something where you need to surpass your previous work, surpassing something like Citizen Kane, which consistently is named one of the best movies of all time, seems daunting. I can see why that could lead to the same sort of paralysis or the same problem of "only working on Big problems/projects" that Hamming mentions in the repeatedly linked here "You and your Research".

I don't think anyone cares about having to install one or any number of client libraries for services being used.

Weave had their reasons. I don't profess to understand the space well enough to chime in, but that much is clear from the twitter excerpt.
But Uber isn't forcing their workers at gunpoint, and it wasn't them that created the situation where the workers have no other alternatives.

If people are forced to get a badly paid job at Uber because the alternative is worse, and you remove Uber, guess what happens to the people you're trying to help?

If we want to help the people using Uber, we need to give them access to a better alternative so that they can leave voluntarily - be it giving them land or whatever. I don't claim I have a good solution, but we shouldn't fall into the Politician's Fallacy¹.

Why do we pay this homage to the National Socialists with tongues firmly out of cheek when our distaste for the Democratic Peoples' Republic of Korea (for instance) is unilaterally considered standard? Unapologetic neoliberalism, I guess, but some slightly less biased verbiage in NPR would be nice to see.

I'm approaching 50 and I think programming is more exciting now than it has ever been. There are so many interesting technologies out there that I want to learn, master, and use (e.g. Elixir, Erlang, Clojure, Swift, Lua, Haskell, and myriad frameworks).

I also like the way open source options have completely eliminated the necessity for me to work with commercial languages and technologies, which I always found a bit tedious.

It truly is an exciting time to be a software engineer. Barring any serious illness or accident, I'm looking forward to doing it for another 30 to 40 years.

Can you quote the "extravagant claims" made in this paper? This is from the abstract:

Taxi drivers got a terrible salary, with a huge amount of the income (as much as 45%, according to the Taxi Commission) going to the taxi companies which own the garages and medallions.

In many cases, they had to pay to work, by dropping $50-$100 on the start of the shift to lease the medallion, before even knowing they would get enough rides to pay for it.

Easy: 2015 there will be roughly 500.000 refugees seeking asylum. An additional large number (about 200.000, but hard to determine) is arriving in Germany and doesn't request asylum. Then there's currently about 135.000 people who got refused on asylum.

Projecting a further rise in asylum seekers, it's not unreasonable to assume that from the currently 100k-300k additional people arriving as either asylum seekers or poor illegal immigrants, it's not unreasonable to assume that about 500.000 people have to be deported to halt the rise in the "asylum/illegal" population. The exact number doesn't matter, currently, we can deport maybe 20K, so even 100k would mean scaling the capacity by a factor of five.

The examples of US and Canada are particularly bad. Yes, they have strict immigration laws, yes they enforce them strictly, but both countries are losing their war on immigration. The US spends 20 billion Dollar a year on immigration enforcement, and some people say there are still 30 Million illegal immigrants. Canada has a lower population, owing to their geography, but they have roughly 300.000 illegal immigrants that they can't get rid of.

Australia on the other hand fights "illegal immigration" by detaining boat refugees on sea for months, or for years in extraterritorial concentration camps ("out of sight, out of mind"). And that doesn't mean that they don't have a population of illegal immigrants living in their country regardless of all their efforts...
It depends what sort of approach you intend to take with this really.

There are several things I'd like to see built, but ideally as open source/free, even if that means providing some financial support to make it happen.

Some of these ideas are about providing a better GUI around an existing library or CLI tool, and some are about providing an open option where currently there are only options tied to SaaS/proprietary services.
The medals were 23K, so about 95.8% gold.

But even if you could pound them into unidentifiable blobs, how would you keep them safe? The Germans weren't looking for medals in particular, they would have taken anything made of Au. "No gold shall leave Germany", etc. etc.
These are very cool, but unfortunately the last time I tried using BLE (specifically Estimote beacons with their sdk) in an Android app the interference with wifi made the experience unbearable. Presumably not all chipsets have the problem, but every single one I tested had trouble.
It seems that for this particular piece of software, there is no cheaper way to produce it. It's a compromise of pricing a product to keep it attractive and being able to do sustained business from the UK, where a team of developers is more expensive that in some other parts of the world.

$500 is affordable for a lot of people. An iPhone 6 costs more. A vintage Symbolics Lisp Machine just was sold for $5150, more than ten times compared to a hobbyist LispWorks license.
IT's pure PR spin. Glassdoor reviews from the past couple of months, both positive and negative indicate to me that the process is very broken and disrespectful.

For instance, multiple people mentioned not being able to get the answer to the problem coded and running with unit tests in 30 minutes.

IF you're testing programmers on the speed at which they code then you don't know what you're doing.

The more productive programmers are slower out of the gate. (EG: think about something for awhile then write it out and produce something that works better and requires less debugging and bashing into shape over the next 2 weeks.)

Even if you disagree with this hypothesis, testing for speed is measuring just one parameter. Apparently they only care if the program runs in the aloted time, not the thought process the engineer goes thru in writing it.
Yeah, pretty good!

One could also argue that it's better to interpret "stay current" as being about "learn new frameworks", but rather "learn important concepts and their applications."

One can write object oriented code (with clear modules and interfaces) in plain-old-C (see "C Interfaces and Implementations"), just as one can write Fortran in Ruby (and I don't mean by creating a DSL sensitive to positions of characters in a line).

So, for those that don't remember what "regular" spider silk is like, or kevlar:

nanomagic spider silk: 5400 MPa (5.4 GPa)
Spider silk: 1600 MPa
Silkworm silk: 500 MPa
Aramid
(Kevlar or Twaron): 3620 MPa
Steel: 450 ~
2600 MPa

If I'm reading http://en.wikipedia.org/wiki/Ultimate_tensile_strength correctly (and comparing the right numbers with the ones from the article...). At least kevlar seem to be in the same ballpark.
