1. I would argue that this is a paper that intentionally goes into detail with regard to the history of statics. After all the main problem here is not how to compute p-values, nor the choice of the threshold (well, that may very well be a problem, but it's a different one) but rather the interpretation, and history is often important for interpretation, even in physics.
If one wants a really compact way to convince people that the way they are thinking about p-values is wrong I'd go with the point raised by Steven Goodman in "A Dirty Dozen: Twelve P-Value Misconceptions": since the p-value is computed under the assumption that the null hypothesis is true it cannot be the probability that the null hypothesis is true, by definition.

2. As far as what the difference is, I have to admit I have not found a memorable phrase to explain it. Both Goodman in "Toward Evidence-Based Medical Statistics" and this paper give a similar wording of the difference, which i would rephrase as follows.

The p-value works by inference, taking the data and assigning a probability to that data, not to an hypothesis. It is to be used to corroborate our disbelief in the null, i.e. informally. To use inference to test hypothesis one must use Bayes' Theorem, i.e. Bayes factors, and introduce prior probabilities.
Hypothesis testing à la Neyman and Pearson is deductive process, in which one does assign probabilities to the hypotheses, paying the price of only being able to minimize the errors commited, not to draw inferences.

One should also confront "In Fisher’s approach the researcher sets up a null hypothesis that a sample comes from a hypothetical infinite population with a known sampling distribution." with "Neyman–Pearson results are predicated on the assumption of repeated random sampling from a defined population."

Given the natural predisposition by students to works in an inferential manner, it may be wise to bite the bullet and teach Bayes factor instead of the p-value cargo cult (this being a pedagogical choice, not an assessment of frequentism vs. bayesianism or a critique of p-values as conceived by Fischer).
Yeah it definitely prompts some interesting questions, especially given the push for universal encryption.
its not exactly accurate or relevant. clip space is 2d because the monitor is.

all of the 3d operations and 3d relevant functionality breaks the argument. the depth buffer for instance, and even more so, the perspective transformation hack (1/w) have limited utility outside of 3D...
I just wanted to say thank you Linus for giving us Git. Before Git I was using SVN and while the wounds are healing, I will bear these SVN scars for many years to come. As a developer Git has made my life so much easier and not only that, thanks to Github I can help collaborate on open source projects as well as my own with ease.

Nobody wants to buy a couple decades of carrier-grade NAT, and the addresses that could be reclaimed won't buy any significant time of anything more open than that.
I don't see how insuring everybody increases complexity. If anything it should increase efficiency. Two more things should probably happen to make this work:

- Eliminate employment-based insurance. Employers should be totally out of the loop

- Have providers post the same price for everybody independently how they are insured

Works pretty well in other counties

Living in Japan and this is dead right. I'd say two decades actually.
Like all performance questions, the answer requires another question: "at what?"

There's been a number of different benchmarks, in a bunch of places. We generally end up in the same realm as C++, sometimes faster, sometimes slower.

Also, many benchmark authors seem to accidentally compile Rust code without optimizations. We're considering switching Cargo's defaults because of this.
The Solarbike is a very real thing
From the Rust website: "Rust is a systems programming language that runs blazingly fast". It says: blazingly fast. What more do you need? Benchmarks? Pft.
Why are "unbalanced" rets not good?

Also, am I wrong that, at least in most Unixish systems, interrupts use a separate stack register from that of user space code, and thus, with care, one can avoid corruption of the direct thread addresses?
its always good to see websites with nice 3d elements involved like this.

started reading the tutorials... and i have to say the quality is questionable. from very big things like the claim that the API is fundamentally 2D (really?) down to small things like doing the pixel space to clip space conversion in an inexperienced way (its one 2d vector multiply or a matrix multiply... surely?)

he is clearly aware of some of this stuff though (he mentions the magic perspective w divide in a later tutorial), so maybe its intended and i am just being over-critical since i understand how this stuff works and disagree with the approach taken to introduce it...

saying that he seems to have confused scene graph with a transform hierarchy. oh dear...
Nowadays you would compute the FFT's on a GPU. And it does really matter.

> Nitpick: 16-bit fixed point is not at the limit of human perception. It's close, but I think 18-bit is required for fixed point. Floating point is a different issue.

16-bit with shaped dither should be good enough to cover human perception.
> is now, pretty high-tech

Oh yeah ? where are the robots then ?
It's so high tech that:

- they actually waited YEARS to embrace smartphones when they came out.

- All electronics makers in Japan have lost to Chinese and Korean rivals

- Most of the "innovations" in Japan never make it to the western market because they are so much made for Japanese only (the Galapagos problem).

- In about every field of Research now the US is ahead, and by far.

Being high tech is not about making dots of new stuff here and there among an ocean of non-innovation, but actually integrating what you improve into everything else. Japan has been particularly bad at that.
> 1. Local branches

Local branches are really an artifact of Git having a garbage collector. That means that any commit that you want to keep must be attached to a branch so that it may not be inadvertently lost. Without a garbage collector, that is not necessary.

In particular, in many other VCSs, you just simply commit without having to create a branch in the first place. Labeling them (via whichever mechanisms your VCS provides) is typically optional with modern version control systems.

You can argue that you prefer having a garbage collector over having to explicitly delete commits/branches that you do not want any longer, but that would be a different issue.

> 2. Mercurial, without extensions, doesn't have the git shelf.

This is sort of incorrect -- or rather, probably a misunderstanding. Shelve is part of standard Mercurial and has been for a while (same goes for MQ). While it is disabled by default and enabled in the extensions section, it's no more an extension in any meaningful sense of the word than git stash (which technically calls out to a shell script [1]). Mercurial's shelf is a python module [2] that is loaded when you flip a switch.

> Both these points make hg easier to learn (branch == clone is very easy to wrap your head around, commit behaves basically like svn/cvs).

This is really more a feature of Bazaar, not Mercurial.

I notice the author of the article is "Sasha Goldstein", I wonder if Ruth and Sasha are related.

Also, I wonder if Sasha would be pinged by the government about who is behind the act, and if Sasha would give them up, adding some irony(?), referencing 1984.
Worth remembering: under many other popular licenses, there would be no possibility whatsoever of legal action that leads to Ubiquiti releasing the full/proper source for what runs on their devices.
You have a very different kind of logic it seems...
Those batteries have a lower energy density and power than the current li-ions, so you won't be seeing them in a phone, laptop or a car.

At the same time they are significantly cheaper to make and durable, which might make them a good solution for home energy storage - paired with panels for example.
Anyway for anyone who stumbles upon this thread I found some bootcamps (Ironhack) that are in EU via bootcamp.in
I read Pynchon, because his books are fun.
Another way to formulate these kinds of blog posts would be to take real world, open source, modern C++ code and convert small parts of it to idiomatic Rust code. Then, the author could compare/contrast the advantages of the approaches there without having to guess or infer if the example is really relevant to the real world.

Snowden was going to Ecuador only after he went public, because at that point it was about politics, not black ops. A little-known individual can be easily taken out in US-friendly countries (see CIA "extraordinary renditions"), that's the threat he neutralized by being in Hong-Kong -- which is not just "China", it's a very complex country with a separate political system where both China and China's enemies have to tread carefully; by saying "he went to China" you're just pushing your own frame -- but then again, you already know that, don't you?
Like stormbrew said, it's all in what you are used to. We currently have both a mercurial and a number of git repos for various projects, and we are seriously considering spending the time to migrate the mercurial repo to git. The context switching from one to the other is really hard, commands don't work the way you expect and things just feel wrong.

Personally, I much prefer git, and I researched both before I used either. But I wouldn't fault someone for preferring mercurial, particularly if part of the reason was that they were very comfortable using it.
Where are hardware encoders and acquisition devices besides Red? Even Android phone are not recording to VP9. Truthfully I do not see the entertainment/broadcast industry moving to VP9. Most places are archiving in a high bitrate intraframe codec and using H.264 as a proxy. Satellite is moving towards HEVC to save bandwidth. I don't see production houses flipping the content again to VP9. The only way to get traction is to get more hardware vendors on board to acquire content natively in VP9. Once there is content more hardware decoding and software editing platform support will follow. Hopefully they will have some big announcements next week at NAB.
I just finished a pretty interesting book on this topic:

"The Cult Of Statistical Significance":

http://www.amazon.com/Cult-Statistical-Significance-Economic...

It basically goes through a bunch of examples, mostly in Economics, but in medicine also (Vioxx) where statistical significance has failed us and people have died for it. As someone who works with statistics for a living, I found to book interesting - but it was pretty depressing to find out that most scientist are using t-test and p-values because it seems to be the status quo and it is the easiest way to get published. The authors of this book suggest a few different things -- publishing the size of your coefficients and using a loss function. In the end, they make the point that statistical significance is different than economic significance, political significance, etc.
I have long had the impression, that those who dislike IDEs only really know products such as Visual Studio or Eclipse, rather than Metrowerks CodeWarrior or ThinkC.

The simple fact that a tool is an IDE doesn't make it good or bad.

I have long preferred IDEs for development on Apple platforms but lately I am working towards moving my iOS development to makefiles with Vim and TextWrangler because Apple's Xcode IDE is so profoundly poorly designed and implemented.

I'd love to have codewarrior for iOS development but they no longer support Apple platforms.
Has it worked in the past? Is this a valid approach? I don't think the customers are the guilty party here.
With something like that, something like the a battery at home could become viable. Even with the lower energy density, it has a few properties that are really great if it proves to be correct: no degradation on cycles, inexpensive and reduced fire hazard.

So imagine the Tesla Home Battery that would currently be double the size, at a lower price point, and could theoretically last a decade or two?

So there are definitely commercial options if it ever proves truly viable and can be easily manufactured.
Mathematically speaking, yes, it is. The probability of any event in this universe is non-zero.

I have an idea for a horizontal forum to solve this very problem. Soomeday I will work a little more on it. But the idea is that you have horizontal rows formed by every new comment direct to the post. And the subsequent comments of the thread are in this row.

This way it is easier to skip to the next comment thread. One thing you lose is the indentation that allows subthread on each thread, but I don't think it is a relevant loss.

And the ordening of the rows a mix of chronology and upvotes.

Indeed. you especially don't need to measure it if you're intentionally not paying attention to inflation.
Where does the article discuss the energy density?

I'm skeptical myself based on the number/style of claims they make, but I can't see any details.
I don't really understand how you read that from my comment. I didn't imply he was lying. I was demonstrating how easy it is to straw man. It's clearly very easy to dismiss opinions you may disagree with by twisting them into something else. "You're stupid because I can mock you" doesn't give any validity to your arguments.

I attended Caltech and UCSC. A couple years ago I went back for a visit. I was appalled to see the entire campus totally deserted on a late Friday afternoon.

What's more, every single exterior door on the entire campus had a card-key lock, with no doorbells. I was hoping to visit the Robinson building, where I once was a research assistant for astronomer Jeremy Mould, but I could not get in.

When I visited Ricketts House I figured there would have to be doorbells, as otherwise the students could not find out when visitors had arrived, but no. I hung around waiting until a student passed through.

"Old Scurve?" he asked.

"Yeah?"

"What class?"

"Ex '86."

I was later accosted by three Institute security guards, dressed all in black with combat boots, like Police SWAT teams. They did not believe that I was a Caltech alum. I kept trying to tell them I was "An old Scurve". They did not know what a "Scurve" was.

For a Caltech security guard to not know what a Scurve was is like it would be for a UC Berkeley security guard to not know what a Hippy was.

Lately the Institute is repeatedly hitting me up to donate money.

I'll be happy too - when they remove the cardkey locks on the Student Houses.
Ellen Pao is wrong about salary negotiation
The VP8 patent pool threat never materialized, but Google secured a license anyway to get other companies to stop complaining about MPEG-LA. A deal is in place for both VP8 and VP9, not necessarily because it's needed, but because MPEG-LA wouldn't stop libeling VPx.
A friend of mine, who worked for EA Tiburon (and later, shortly for Mojang) was a Junior Programmer on Superman Returns. He always thought we (our irc channel) were making fun of him for being on the project, but really, half were envious for the sheer work experience, and the wisdom on how to pick good software projects later, that came with it.
Such a classic. Unfortunately. And they probably have nothing to fear.
edit: all of the above is incorrect and I retract this.

If Ubiquiti is in breach of the GPL then their customers cannot receive a license to the infringing work by Ubiquiti distributing it to them, so they're infringing too.

I don't think this has been done before. It would definitely chill the acceptance of GPL software in general.

edit: all of the above is incorrect and I retract this.

You are correct in your assessment of the main purpose of CMMI. But note that you need a repeatable way to build something before you can improve its quality. It doesn't do any good to build 100 units 100 different ways if you're going to try to make them better.

However, I have to take issue with the statement that software engineering is always building something new. That's only true if you look at new houses being built and say they are each fundamentally different. Most software is very similar to many products before it. A large part of the reason that we need a Body of Knowledge is to extract the common parts and automate the making of them, or at least automate the process of making them.

I agree. And I'm so blind I can't see my own country (Australia)'s fixation. I bet it's immediately obvious once pointed out however.
From the article (thanks @timdoor) :

"Freight Farms’s repurposed shipping containers, packed with LED lights, sensors and hydroponic systems and producing lettuce and herbs, are appearing in vacant lots and alleys. The sealed containers can yield about 500 full heads of lettuce a week, year-round—even in Minnesota and Canada, where some of the 25 units sold so far by Freight Farms now operate. Co-founder and Chief Executive Brad McNamara said the units sell for $76,000 each and require no pesticides."

- locally, a head of lettuce is $1.25 (Tucson, Arizona close to lettuce growing areas)
- 500 a week makes $625 a week, or $32,500 a year in revenue - average $2706.25 per month revenue.
- a 5 year lease with $1 buyout on $76,000 would be $1580.80 a month based on terms I used to sell capital equipment for.

$2706.25 - $ 1580.80 = $1125.45 per month, before paying employees, electricity, and cost of location.

What does lettuce cost in other areas?
Even at only half the power I'd want one in my phone. It's easy enough to charge a phone if it only take a few minutes. It's the hours that it currently takes that makes frequent charging intolerable.
some day, the yung'uns are going to look back at LP, and put him in the same category as K & R, Pike, Carsten Haitzler, or other visionaries.
