> I'll say it again. If you correctly measure (exercise left to reader) a p-value of 0.05, that measurement explicitly means that you expect that 95% of your future observations to be consistent with the hypothesis which you used to determine that p-value of 0.05.

What do you mean with "measure a p-value"? You make your observation, calculate a statistic (a function of the observation), and look at the distribution of that statistic under the null. The p-value is, by definition, the percentile of the value you got in that distribution (which might or might not be the actual distribution).

You want to check if a die is loaded to yield 6 more often than it should. The null hypothesis is that the die is fair. You can calculate the distribution for the number of 6's in 3 rolls (0: 58%, 1:35%, 2: 7%, 3: 0.5%). You roll the die three times, you get three 6's. The p-value is 0.005. Do you agree? The p-value is 0.005 whether the die is fair (the null hypothesis is true) or loaded. Do you agree?

> Making future observations that are consistent with a known hypothesis is exactly what reproducibility refers to within the context of science.

Scientific experiments are usually about rejecting the null hypothesis. For example, the null hypothesis might be that there is no Higgs boson and the peak observed in the LHC data is just noise. They made their analysis and rejected the null hypothesis (p-value less than 0.000001, do you think they calculated it properly?). In this context, reproducibility means "finding the Higgs boson again if the experiment is repeated" and not "repeat the experiment and get a result consistent with the null hypothesis".

According to your description of the limits of p-value analysis, the only conclusion that physicists should get out of the experiment is that if they do it again they should expect to get results consistent with the null hypothesis (i.e. no Higgs boson) with 95% probability. But they see it as evidence that the null hypothesis is false and the Higgs boson real.
I'm really coming around to the idea of car-free Sundays. Even from something like 5-11 am I think a lot of places would really benefit from that.

This Sunday I participated in marathon/half marathon and it was great to see the streets empty except for runners, occasional cyclists taking advantage of the closed streets and lots of pedestrians watching the crowd but also filling the cafes everywhere.

You specifically mentioned Australia - while Melbourne is flat and cool, both Sydney and Brisbane are hilly and hot for half the year. The country also has insane helmet laws, so that even the bike-sharing programs are essentially unused simply because you have to wear a helmet or face a fine. So the bikes sit in the sun and rain and virtually never get used.

Removing the helmet laws for adults would go a long way to higher adoption in the dutch model. But 'safety' laws are hard to ratchet back, given all the effort that went into telling people they couldn't be trusted with their own judgement in the first place.

> While both the coal dust and Chernobyl future deaths are somewhat statistical in nature, there is a huge difference that you would acknowledge if you were sincere.

OK then, I sincerely acknowledge that the estimate of 4000 Chernobyl casualties is much more widely accepted (including by the nuclear industry) than the WTO's more speculative guess at how many people are having their lifespan reduced by exposure to coal particle dust. I'm not sure why you would think otherwise, but then I'm also perplexed by your assumption that none of the 3940 total casualties the WHO predicts from increases in rates of cancer and leukaemia among those most closely exposed to Chernobyl radiation have happened yet.

The lack of confirmed Chernobyl deaths is because - as the report you linked to states - cancers are common cause of death among people not exposed to nuclear accidents, not because 50 acute radiation sickness victims and 9 kids with thyroid cancer are the only people living or working near Chernobyl to have died a bit young over the last 30 years. I mean, I'm not sure any individual lung cancer has been directly proven to be a result of working down a coal mine either, but it would be an unusually outspoken proponent of coal that argues that it should be discounted as a risk altogether because of that, or because of difficulties gauging the precise size of the effect when miners tend to be poor and smoke a lot.

I'm going to go out on a limb and consider a published study
suggesting nuclear is around 14 times safer than coal[1] and 1.5 times safer than natural gas a little more valid than your own back-of-the-envelope exercise, or indeed a blogger whose use of statistics is rather creative.

[1]though much as with flying being safer than driving, that's to a large extent because nobody is suicidal enough to run a nuclear plant with safety standards comparable to those of Chinese coal mines.
The IBM 1401 was pretty exotic for it's time, but there was a more common product using toroid memory even earlier than the 1401.

Seeburg's line of jukeboxes from 1955 onward used this mysterious system called TORMAT, which essentially was a 160-bit toroid memory device (for a jukebox that held 160 selections). Bits were flipped on as you paid for choices and the loading arm seeked the next record by checking the bits in memory. This also had the positive side-effect of people selecting the same record not resulting in multiple plays, since you were flipping on a bit that was already flipped.

https://www.flippers.com/Seeburg-tormat.html

The TORMAT was used up until 1974, when it was replaced with silicon-based memory.

Dave (EEVBlog) probes monkeys ass to bust Batterizer
It appears Taubes has been bitten by a meme. The subjects in the NIH study consumed isocaloric diets and were put in a chamber that measured all of their thermodynamic outputs -- it turned out thermogenesis was a tiiiiiiny amount higher on one diet. Why is that? Well, the "loading" (pre-test) diet was mostly carbohydrate, the low-fat diet was also, but the low-carbohydrate diet was mostly fat. After only six days, the subjects' metabolisms were still adjusting to the diet. Where did I get that idea? It's in the study abstract:

> Mathematical model simulations agreed with these data, but predicted that the body acts to minimize body fat differences with prolonged isocaloric diets varying in carbohydrate and fat.

Even some of the media stories, like the one in your first link, quote the author of the paper saying this:

>Indeed, Hall's mathematical modeling predicts that in the long term the body acts to minimise body fat differences between diets that are equal in calories but varying widely in their ratio of carbohydrate to fat.

>"Over the long term it's pretty close," says Hall.

You'll recognize Hall as the first author of the study. Let's be clear: the lead author of the study said in plain English that there was probably not a significant long-term difference in energy usage resp. composition.

Why is the media blowing this up? Because they just want a story. They want nutrition to be an argument, rather than a gradually developing science with occasional surprises.

Their goals are at odds with researchers who want to make useful information about nutrition available to consumers. That includes the New York Times. Keep that in mind.
I don’t disagree that AirBNB in its current form is a fantastic idea, just that the original idea was dumb. It is great that they were able to pivot out of their original dumb idea (and all credit to them for doing this), but this doesn’t change that the original idea was bad.

What I am objecting to is the idea that it was a good idea that just sounded bad. It was simply a bad idea that also sounded bad. If their original idea was we will develop a platform that will allow people to run an illegal hotel with their competitive edge being to send around professional photographers to make the properties look better than all their competitors then I would have said this is a great idea that sounded like a great idea.

Edit. I am surprised that someone has not tried the same approach with private car sales (maybe they have). Good photographers are cheap these days so it would be possible to create a car sales site that offered free professional photography of the cars.
> How hard your body holds on to calories is genetic.

You realize this statement makes no sense right? It is also incongruent with your latter statement. Calories are merely units of measurement of energy. If you eat too much (compared to what your body uses), those energy will be stored as fat.

Yes, I am aware that how fast your body sheds fat is genetic, as well as how hard your body holds on to fat cells. That's all kinda part of your TDEE. If your body is the kind that holds on to fat cells more, tough. You just have to eat a lot less, and move a lot more.

Less and more is defined by how much your body uses energy. If your body uses only 2000 kCal a day, then if you want to lose weight, you simply eat less. If you have a body that dictates you use 1600 kCal a day, then less is simply less than 1600.

It's really that simple (well, in writing... in practice, the discipline issue definitely comes into play)

Great article. I'm working in a talk about Developer Flow and TDD and towards finding that elusive zen like state where the TDD you are practicing helps really drive out the design and strongly guides what to code next, and next and next. Specifically that TDD can be used to find this nice developer rythm.

Has anyone had this experience/success with this? What can help make the difference towards getting that nice flow out of TDD.

I'm inspired by Corey Haines and a bunch of code experiments he's illustrated over the years. One technique that struck me was that a nil return from a method was was an expected and desirable step during a TDD cycle and that guard clauses can be very helpful to driving out TDD designs while maintaining flow.

I'm looking for similar patterns for TDD decision making, especially those that help the dev stay in a good rythm.

Would love any ideas towards exploring this further.
I believe Q/Kdb+ to have the most natural implementation of IPC that I've seen, as long as you can keep all your gear inside Q.

To connect to another host you just do:

remote:hopen `:server:port;

The port number is specified with -p on the command line. To send messages:

answer:remote "sum x"

or if strings are repulsive to you you can pass in an expression like: answer:remote (`sum;x). `sum here is a symbol which is like a reference to a variable (or function). You can also pass a literal function for the remote host to execute, since they're just data.

You can also do asynchronous calls using the negative value of the handle (which is just a file descriptor int, wildly enough): neg[remote] (`incViews;`welcomepage;1)

Completely natural and simple. The only issue that I'm aware of is a 2gb limit for each message. Built-in functions can split your data into blocks to transmit large amounts.

The in-memory representation of data and the network representation are essentially the same. So there's no costly per-byte packing or unpacking going on, simply a memcpy(). In terms of performance and power use (environmental impact) this is a huge win.

It's trivial to expose data to the outside world by creating a web server. Simply define a function called .z.ph (or .z.pp for POST). This one evaluates the URL requested as a Q expression and returns the result as json.

.z.ph:{.j.j value x 0}

Being able to build services as simply as this allows you to begin to think about the microservice as the unit of program composition, rather than classes, functions, or modules. Microservices have their own issues, but that's a topic for a later rant.

This is a very impressive scale-model jet engine powered by an electric motor. But it's definitely not a "fully functional Boeing-787 jet engine", as the title misleadingly implies. A fully functional Boeing-787 jet engine could power a Boeing-787, and could not be printed out of plastic (since it would burn up as soon as you ignited the jet fuel).

Ask HN: Does Meteorjs really lock people in? (Brought up by Feathersjs)
I've been thinking about starting a project lately and I can't decide which path to take. It's going to be a relatively large project and I'm worried about exactly what the feathersjs website states:

(Direct copy pasta http://feathersjs.com/):

-start-

Feathers vs Meteor
"Once you go Meteor, you don't go back. And not in a good way."

Meteor has amassed a large community and a lot of venture backed funding. Our biggest complaint is that because of this funding, there is some serious lock in. Meteor has it's own package system, how you use npm modules can be inconsistent and it is a large codebase. There is also the risk that when investors start pushing for a return on their investment, it could negatively impact the community.

From a feature standpoint Feathers is pretty similar to Meteor. You get real-time API's from both. However, we let you use the defacto npm for managing dependencies, we let you choose whether you want to use Webpack, Gulp, Grunt, or any other tool for managing assets, and Feathers is completely client agnostic without any additional overhead. Everything is open, flexible and pluggable. You use only what you need.

-end-

I actually have no clue about the feathersjs project or an opinion on them. I do however like the point that they are addressing. Specifically the npm modules (or lack thereof in Meteor [when you're building your own stuff]), but the other components too.

The community didn't reinvent "ASIC". It was my joke, but humour is difficult ... Read the conclusions of my dissertation. Then realize that the cloud is just one form of special-purpose hardware. Then be me trying to tongue-in-cheek claim that I foresaw the potential of rump kernels on the cloud 4 years earlier. Then maybe the joke will be funny. If not, well, you don't get your money back, sorry, your only condolence is that I rarely use the same joke twice.

I still don't see too much similarity between DDE and using full-OS VM's to act as DDE backends. It's like observing that unikernels and traditional timesharing operating systems can both run applications, so they're similar. Yes, but ... Anyway, I understand what you mean, disagree, and don't think it's worth debating further.
> Because gun is not a database (NoDB), it is a persisted distributed cache. The fatal flaw with databases is that they assume some centralized authority. While this may be the case initially when you are small, it always ceases to be true when you become large enough that concurrency is unavoidable. No amount of leader election and consensus algorithms can patch this without facing an unjustified amount of complexity. Gun resolves all this by biting the bullet - it solves the hard problems first, not last. It gets data synchronization and conflict resolution right from the beginning, so it never has to rely on vulnerable leader election or consensus locking.

That's some of the most hand-wavy drivel I've ever read.

Programming Tip: Tag your source code to assist the developers
You posted this the other day, at https://news.ycombinator.com/item?id=10136522 , saying then "The forum [post] was the last attempt" after trying all other avenues.

I totally get that you are posting this here partially out of a sense of frustration, partially to get people to know what's going on, and I presume also to get support.

I think - and this is conjectural - you would get more public support if you include a few more details, such as:

"I purchased/downloaded a copy of xIDE from Qualcomm" (as the GPL does not apply upstream when you got it via a third party), "It contains versions of binutils and gcc which are licensed under the GPL. I verified that these are under the GPL copyright by doing XYZ. The license requires that there be a way for me to get the source code from you. Despite many attempts at asking CSR how to get the source code, I have received no answer. This appears to be copyright infringement. If I do not get a response soon, I will be contacting the copyright holders, who have a successful history of prosecuting copyright infringement cases."

Unfortunately, that would only help improve public empathy. There is nothing you as a customer can do directly because you are not a copyright holder and have no standing to sue over copyright infringement. Abstractly speaking (since we know this isn't the case here), it could be that CSR has a special waiver to let them use binutils and gcc without having to follow the GPL. You do not know that, nor can you compel them to reveal if they have such an agreement.

At this point, your next step should be to read and follow http://www.gnu.org/licenses/gpl-violation.html .
