Here is a good summary of the state of EmDrive testing (as of a year ago): https://www.reddit.com/comments/34cq1b/

TL;DR - a small, experimental division within NASA called Eagleworks tested the device. They are a very small group with very limited funding tasked with exploring unconventional theories around advanced propulsion. Their results were not published in a peer-reviewed journal, and there is considerable disagreement as to the validity of their experiment. They are continuing to refine their experiments, and the last update provided is that they intend to publish a peer-reviewed paper describing an experiment that successfully breached 100uN of thrust, which was the target needed for JPL and others to attempt to replicate their results.
Yeah and there is already an improvement to that: https://github.com/JuliaLang/julia/pull/12541. Well, anyways, I think you can easily find a lot of unsatisfactory constructs in any language, especially in young ones ;) If they outweigh the advantages is debatable. So far I've been finding satisfactory workarounds for the most daring issues, so for me the conclusion is indeed very positive.
No clue if it's a good idea or not, but https://hackaday.io/project/5596-em-drive seems to be pretty much shooting for that.

Let's throw schools in there... no use taking a 20k raise to move to Chicago if you have a child for instance. You'll pay more than that for the cheapest private school. If you want to use neighborhood schools you can move to Oak Park... and pay 20k in taxes instead...
Having thought about this a lot, the best definition of life I've been able to come up with is as follows:

An object is considered to be alive if it consumes energy to create or maintain its own order (in opposition to the general effect of the second law of thermodynamics in the wider system in which it finds itself).

Although this doesn't exclude crystals..! :/
Any ideas on a ballpark of what it would cost?
A very small team[1] at NASA did indeed test it, but their results had problems[2]. Also, results from any source can be reported on poorly.

From the article: But New Yorkers, like everyone else in the United States, can take solace in two simple facts. The first is that Zika virus can’t easily be transmitted from one person to another

Who gets to decide what is "harmful" and what isn't? Why is it necessarily better to have one animal species in a certain area rather than another? Valuing native species over invasive species seems like an arbitrary human value judgment.
(I don't necessarily disagree with eradicating invasive species, but I've noticed that people often haven't thought it through or considered their biases.)
Yup. At the EagleWorks lab which many people confuse as not part of NASA (though it very much is, and exists for testing exactly stuff like this)

Maybe... but I saw recently that the PS4 is outselling the Xbox One two-to-one. I'm not on top of that world enough to know all the reasons why, but the "ring of death" could be one.
Why don't we kill off some of the humans instead? It's sad when a child dies of malaria, but anymore I'm wondering just what makes us think we deserve to be here more than any other animal, insect, etc? Epidemics are tools of nature to deal with an unbalanced ecology.

People are far more destructive to the environment and have been around for far less longer than the mosquito, which has been here since the beginning.

At least something like a mosquito is honest about its intentions. It wants to have a handy blood meal from you. A human, on the other hand, will engage in varying forms of deceit, deception and then probably fuck your mother behind your back, before they sucks you dry.

Which one would you rather have around? Something to think on next time your get bit by one.
What's wrong with this? If SA was indeed responsible for these attacks, shouldn't they be held liable for compensation to the victims' families?
I wrote mup [1] to help with this: it is a markup previewer. It support multiple markup formats and for markdown multiple markdown implementations: pandoc, commonmark, kramdown, python-markdown and also previewing using GitHub API (slow but the most reliable for README.md editing)

If "outsiders" actually knew how peer review worked, I don't think it would give them a great deal of confidence. Peer review literally means that a few other people (often two or three, maybe five at the outside) looked at a manuscript and failed to find anything too objectionable. Since these decisions are just based on a few people spending a few hours, you might expect this signal to be a noisy measure of quality, and it is.

NIPS, an excellent machine learning/neuroscience conference, ran an experiment where 10% of the submissions were reviewed by two separate program committees. They found considerable disagreement between the two committees (~60% of the selected papers were different) More details here: http://cacm.acm.org/blogs/blog-cacm/181996-the-nips-experime...
People make the mistake of equating editorials with political news. They are not the same thing. The opinion section, the pages that have OPINION in big bold text at the top, are forthrightly conservative/libertarian, even though they have at least one regular liberal opinion columnist (William Galston) and constantly have guest articles written by politicians and business leaders of all stripes. The news sections are totally different and are pretty unbiased.

On topic: I'm not a biologist so here's my layman's TLDR, please tell me if this is close.

1) You can tell whether a protien has this viral property by looking at its amino acid sequence

2) Looking at this seqence has shown several reasons why proteins don't often go viral

- The relevant region ends up on the interior of the structure
- The relevant structure is not mechanically likely
- Evolution has come up with tons of biological tricks to prevent it

Off-topic: That is some of the grossest academese I've seen in a while, and it makes this passage near unreadable. I'm saving this sentence as an example for students of what not to do:

> The elucidation of this code has enabled the identification of factors that determine the intrinsic aggregation propensity of these molecules

I'd have a hard time coming up with a sentence that feels more inside-out than that.
I have tried several summarizing services but none does as good a job as a real human. Try to take some article that you haven't read and run it through an algorithmic summarizer, most of the time it wil be a very poor experience, specially so when compared to say a friend explaining it to you in short. Thats what wise guy is. I don't believe in the forseeable future AI will be able to beat humans at this but if it gets close it'll only further improve our unit economics.

Currently our unit economics on staff analysers look something like this WITHOUT any tech assistance:

Median wage in low-income english speaking country: $2/hour

Analysis time for a average length 1000 word article: 6 minutes

Actual cost/article: 20 cents

Average Views per summarry at scale: 20 (Extremply conservative estimate, the Apple summary got 1000 views in an less than an hour)

As you can see the average cost of Human summarizing/view is less than a cent. Such a service at such a low price point should be seen as valuable by a large number of people; or at the very least sustained by advertisment (though I would very much prefer a subscription or micropayment based business model)
Relying on the PG user/role system doesn't feel general enough to me.

A better solution would set a query on the connection that constrains which rows it can touch. I know this ends up being more complicated and less performant but it splits the difference between app-level and database-enforced security.
How much funding?

A Falcon 9 can lift 10,000 kg to LOE (or more). Let's say we could get a simple Em-drive and basic satellite and solar panel in for under 100kg. (We can do better, but let's start there). That's 1/100 of the load, so (in theory) we could maybe pay 1/100 of the $60m cost for a Falcon 9 lift, or $600,000.

Half a million bucks plus some change, let's say.

Edit: Less if we can get on board a previously-enjoyed rocket!
No, they could not pass it on day one. Getting legislation together like this takes support building in other areas of government, and getting it right so it isn't toppled because of flawed wording takes crafting. They need to bring people on board and do it well or it falls apart. It takes time.
Cartel, like in a corrupt system, right? Maybe just what I've said?

If you can get in the healthcare industry in the US you'll be a genius. Or probably a criminal, there's no legal way to get out of the current status quo without government intervention.

I like the free market, but you're oversimplifying reality.
Thanks for the feedback. I will add a “latest reviews” list to the homepage ASAP - some others have suggested this also.

Correct, we are not aiming for code reviews but for package quality/reputation. Hopefully the descriptions on the homepage are clear and this does not confuse too many people.

Regarding the problem of outdated reviews - I have a specific field where the reviewer can put the current version that they are reviewing (example: https://goo.gl/rWMHgB shows version 4.8.2). Reviewers can also easily update their existing reviews and bump this version as necessary. We also show the date that the review was last updated.
But no increase in discretionary income can ever resolve worries about spending on positional goods[0], which the wedding is -- since positional goods involve spending to achieve a rank relative to others, then achieving a certain rank will be just as burdensome, regardless of how much wealth the middle class enjoys, since the highest-ranked people will blow an "uncomfortable" amount to get the high rank.

You're right about those other goods though: if people have to shell out all their discretionary income to cover some minimum baseline in those categories, then that is a solvable problem. Arguably, though, education and housing have become positional (and thus intractable via discretionary income) because people are trying to achieve a relative rank through them, not some baseline of quality.

[0] basically a good that derives its value from its ranking relative to others, not absolute metrics https://en.wikipedia.org/wiki/Positional_good
I'm a journalist; lots of my colleagues were floored watching the doc about the NYT, "Page One," when David Carr tells his editor, "I'm doing two more weeks of reporting on this, then it might take a week to write it and show it to you."
Hacker News would be immensely more valuable and useful to me if a poster such as abhi3 posted such a well-written summary on every story.
To be fair, VC's aren't usually exactly after changing the world, they're looking to invest in successful companies. Inkjet printers and Keurig have been extremely successful, so you can't exactly fault VC's for funding the wine version of it.
We use it in production at QuantifiedCode, so it's pretty stable but still a bit undocumented (which we will fix soon).
> inertia must quantized at small accelerations.

as everything does :) I think it is quantized at all levels, it just becomes noticeable at low levels as usually.
I don't get it. Are you saying in parliamentary systems legislation is only passed the day a new government assumes power? What do they do until the next time elections are called?

Others have mentioned that this isn't really relevant, but I'm just going to recommend at least reading the novella, and avoiding the movie.
The Guardian is simply wrong. The Liberals fought the last election on a promise to legalize, and just today in Question Period Trudeau rejected calls to decriminalize first, saying that it does nothing to keep pot away from kids and legitimizes a significant income stream for organized crime.

It's simply poor fact-checking by the Guardian.
sorta, kinda...
It is true that some scientists at NASA have done experiments with this where they claimed to have found some result. A lot of other scientists were very sceptical about these results and said they weren't rigorous enough in eliminating possible errors. The same scientists have done other controversial experients and made claims that other scientists found overhyped.

NASA is a big institution. It's a very different thing to say "NASA said XY" or "someone at NASA claimed to have found XY".
How do the tools change every month? If you're starting projects from scratch, pick one tool and stick with it.

If you're jumping on different projects, well the people that set them up used different tools. It's no different than jumping between a .NET C# app, a Rails app, or a Spring MVC app.
No matter how heavy you made the bike wheels, any kinetic energy stored in them would be used up in the first few meters of a steep hill on any road course. Then you have to drag those heavy weights up the hill. So no, more storage in the wheels isn't better (outside of a totally flat track).
> After most compilers started properly supporting the newer C++ standards, it seems there has been an increase in the amount of love that C++ libraries are getting.
Sadly there are many more compilers out there than just gcc, clang, icc and msvc++.

Many of those aren't still C++11 compliant, specially in mainframes, classical commercial UNIXes, embedded real time OS and certified compilers.

But it is true, thanks to the productivity of latest standards, there has been an increase in C++ visibility, specially thanks to Microsoft.

People like to bash their C++'s compliance, but they are the commercial vendor with the more up to date support, even than icc last time I checked.

Also they were the main sponsors for Back to native conferences and eventually making it together with CppCon.

https://blogs.msdn.microsoft.com/vcblog/2014/04/03/cppcon-th...

Also Windows Phone is the only mobile OS where C++ is a first class language.

>. A lot of people like the to say that [x] is superior to C or C++ - often ignoring that their favorite language's libraries/runtime/compilers/vm is most likely implemented in the very same languages they are putting down.

A lot of people like to point out that fact, ignoring that many compiler writers tend to use C or C++ out of convenience for existing tools instead of bootraping the full eco-system around a new programming language.

Many use the same route as Go, using one of those languages and when the toolchain gets mature, those parts get re-writen.

All in all, I do like the language, now if we could get rid of those C underpinnings...
For the union of the automata, do you mean intersection? Maybe when I look over the transducers post less quickly I'll see my mistake.
Why pricing for IoT is so confusing
Many Dutch cities take active measures against drug tourists. They are not a profitable or desirable crowd. Besides, most drug tourism is and always has been from countries where drugs laws are still (relatively) strict.
Interesting because I was having a conversation with a colleague today complaining about other teams at work we depend on for Oracle services that can't do HA. Not sure if they don't know how, if they just don't think it wokrs, or if it's too pricey for them. But we have a vendor product that needs a DB and our users don't want any downtime. Curious if Citus can fill that gap in the HA space.
> The hard part for physicists to accept is that the theory requires the speed of light to change.

I'm a complete layman here, so I don't understand how the link you shared says that the speed of light is changing; it seems more like a change in the way we define the speed of light. Is that right?

If the actual speed of light is to change, how is that possible? We've experimentally verified it up one side and down the other, so this seems like a huuuuuge discovery.

That's more likely explained by the fact that PS4 launched $100 cheaper and is more powerful.
Aedes mosquitoes are indeed "invasive" in much (arguably, most) of the world.
Yes, I understand we disagree. That's why I was explaining why your interpretation didn't seem to square with the things people do and don't find funny.
I think what I most enjoy about the possibility of the EmDrive is that it's similar to how things were often discovered during the "golden age" of science.

Often, engineers or inventors would create something and then scientists would have to explain why it happened. In the last few generations, physicists and mathematicians would come up with theories and engineers would have to build equipment to test those theories.

The EmDrive is one of the rare modern situations where someone has engineered a device that shouldn't work according to what we know and the scientists are having to come up with the explanation.

Personally, solving a mystery is more exciting than purely intellectual theories and the EmDrive has created a very interesting mystery.
> The models affected by this do not use DEF[1]

Huh? Some certainly don't, but 2014 TDI Passats like mine use DEF. My reservoir currently lasts about 10000 miles, which is also the manufacturer's service interval.
Wow, that's crazy, a laser/computer combo mounted on fence posts, which is able to determine the type and gender of insect, and only shoot the right kind of disease-carrying mosquitos. "the Photonic Fence can kill up to 50 to 100 mosquitoes a second, at a maximum range of 100 ft."

Also interesting, I thought Intellectual Ventures was only a patent troll, I didn't know they did actual research work as well.
I never owned an xbox, but for games that require a controller and suck with a mouse and keyboard, the 360 controller is the best one I've used.
They should have added that to the 30k each peaceful pepper-sprayed student received...

Of particular interest to me is the fate of the cop that sprayed them... I was thrilled he was fired.

John Pike was subsequently fired, despite a recommendation that he face disciplinary action but be kept on the job. As of August 2014, Alex Lee was no longer listed in a state salary-database as working at UC Davis.[5]

In October 2013, a judge ruled that Lt. John Pike, the lead pepper sprayer, would be paid $38,000 in worker's compensation benefits, to compensate for his psychological pain and suffering. Apart from the worker's compensation award, he retained his retirement credits. The three dozen student protestors, meanwhile, were collectively awarded US$1 million by UC Davis in a settlement from a federal lawsuit, with each pepper-sprayed student receiving $30,000 individually.[6]

He lost a job that pays 6 figures for being a terrible human being. http://www.sacbee.com/site-services/databases/state-pay/arti...
No, that doesn't explain anything. Durov has a lot of money to throw around. Okay. Why did he throw it at something silly when Telegram has real problems? NCC Crypto Services would do a lot of good work for a million dollars.
It takes about $100k to get a cubesat into orbit, plus costs for building the sat itself (custom fabricating a miniaturized drive plus a suite of sensors).

So not much, but the larger problem is we don't know how this drive works. Miniaturizing it could impact performance, as could other electronics in the satellite... given the unknowns it makes sense to let NASA do some more terrestrial due-diligence before going to space.
If the objection is the alleged difficulty in installing competing app stores, why isn't the relevant market the market for apps, rather than the market for phones?
There are so many variables in leo. Magnetic field, ions, drag, radiation pressure from the sun, radiation pressure from the earth, variable gravitation fields due to the irregular nature of the earth, and I'm not a rocket scientist, so I'm sure there are many more I'm just not thinking of.
Maybe they like the people cutting. Maybe the people do other jobs as well, like moving the wood in or out?
Antitrust law is concerned with unlawful contracts, collusion, and cartels. It's meant to ensure that businesses compete by acting independently.

Apple is acting independently. They've built differentiating features (like custom software) which you can only get by buying Apple's products. Apple hopes that customers will use their products because they're better than the competition. That is exactly what antitrust law is meant to encourage.

Google is not acting independently. They've built differentiating features, but licensed them under terms that prevent competition. Google hopes that customers will use their products because OEMs are contractually forbidden from selling competing products. That is what antitrust law is designed to prevent.
by what algorithm have you determined that it has been detrimental? how do you know that algorithm is accurate?
And various interests building products based on Android will fund it or directly contribute. Note: Development on Linux happens.
The new version of Basecamp is pretty smart about notifications. If you have the site open, it doesn't send you a ton of email. It also has something to disable notifications during certain times of the day and catch you up later (probably in one longer email.)

Sadly, some people need those emails to keep using the tool everyone else is using directly. I wish it wasn't like that.
You also have to add in the payload integration fees, testing (very, very expensive), the actual payload development, insurance, and also be in a launch configuration such that you can piggyback behind a payload taking up most of the F9 capacity.

I'd be astonished if the cost of this was less than $2-3M.
I don't if it is bad, but I think that it just means that some computation isn't being done in full, and that's why you have to tell it to finish.

Explaining better: any program should have the information saved when you click it to save, or at some specific time. If I don't save, ok, no problem loosing it. But opening a word processor and then turning the computer off shouldn't make the processor crash, or go through some recovery, or complain about something.
He just means they didnt have to wait for anything or anyone. If they're being well behaved they will have some due course and debate etc. But in Harper's government we often saw how fast things could go through the gov't with a majority, little debate/discussion or public notice even. Yay canada.
