The main problem is that with floating point numbers, (a+b)+c is different to a+(b+c), so almost any change can produce slightly different answers.

Also we have the problem of what is "right"? Maybe your first implementation does (a+b)+c, then someone finds doing (a+c)+b gives a more accurate answer. Should we change?

Then you are given two CPUs. If I want to do x1 + x2 + ... + xn, then obvious thing to do is going to be to give each CPU half the input data. But now however I split will give me a (slightly) different answer.

With matrix multiplication this is much worse -- all algorithms chop the matrix into little pieces in different ways, each giving a slightly different answer. Even if you try to define some plain simple algorithm, it will usually give a less accurate answer, due to how the floating point rounded!

With integer matrices on finite fields, it is much easier to get what you want, 100% reproducability.

Is this similar to the Twizy[1]? I believe in the UK these are registered as motorbikes (edit: no, they're quadbikes), although they sort of look like small cars. I even saw someone driving one a few months ago.

This card must be used to pay for gas purchases, where you'll be charged triple the amount at the pump.

In addition to being a unique financing model, that seems like an interesting psychological incentive to avoid unnecessary trips. Basically a personal gas tax.

But I'll bet the race will be on to bypass the card and fill the car with market price gas.
The talk is very explicitly a tutorial for a few good statistical methods for those without a statistical background, using simple tools "hackers" are familiar with and are occasionally necessary, especially in the case of bootstrapping. This isn't hacking in the sense of "growth hacking," thankfully.
Are you seriously trying to use a blog post with zero referenced studies to back up your opinion? Was I supposed to be impressed by the harvard.edu domain? Did you even glance over the wiki page I posted above?

Low/zero carb diets are unlikely to be the holy grail for everyone but if you want to argue, at least spend some time reading up on the actual science involved, rather than blog posts by unknown authors.
Definitely not. Ask most doctors if an MRI is warranted for an autism diagnosis and they'll laugh at you.

Part of the problem is that autism significantly impacts social function. So does prejudice. So the minute you label someone as autistic, it becomes incredibly difficult to say how much of their daily challenge is due to inability to perform socially and how much is due to other people perceiving them differently and treating them differently.

The other thing is that many traits seen in autistic individuals and used to label them as defective are also seen in other situations and not viewed as pathology. One example I know of firsthand: The tendency to be very literal is also seen in highly intelligent and highly educated individuals and is a hallmark of good scientific work. But in a person diagnosed with autism, it is pathologized rather than praised as a virtue.

It's a complicated situation.

Edit: I apologize. I am leaving the comment here, but I feel like I replied to the wrong person somehow. Perhaps it should have just been a general comment and not a reply to. I have two sons who are not formally diagnosed but likely would qualify for a diagnosis somewhere on the spectrum. I have nothing but sympathy for your frustration.

Pretty sure I read about this from the libertarians in Reason at least a decade ago. Amusing to see a few people catching up.

What? I have no idea what you're talking about.

Sprawl was fueled by tax and land use policy, where the urban areas were looted to subsidize McMansions and track housing.

The recent sky rocketing rents are caused by a massive demographic shift and urban areas not upzoning fast enough, allowing supply to meet demand.

Pretty simple cause and effects here. Exhaustively documented.

Urban elites? Is that the new pejorative for "reality based"?
In principal there is nothing wrong with what you say, it's just that you need to now keep track of every possible change to the code and the environment.

For what I am proposing, keeping track of the major versions of dependencies should be enough.

See also sibling comment.
It's actually the opposite: the "hacking" is used to provide better data and analysis using programmatic techniques (bootstrapping, cross-validation) than just by taking a spot average in Excel as gospel.

I've seen many, many data scientists from startups write blog posts with skewed data without using such techniques and failing to identify the potential statistical problems.
Let me say the same thing perhaps more clearly: there isn't any nondeterminism here, just failure to capture the inputs and outputs of a deterministic code transformation.

Suppose CPU count is the configuration input. Then you have a deterministic macro function M(nCPU, abstract program) => concrete program. And another deterministic function C(concrete program) => CPU instructions.

Now nCPU is no longer a random piece of information randomly found in your environment: it's data in your data set. And your results are bitwise reproducible.

With a reproducible toolchain, I can use a 1-CPU machine to get the same results as you did on your 32-CPU machine, by using the same data set (including your nCPU=32). Why? Because I'm reproducing your results and I care more about precision than performance.

You can't just go private. You have to buy out shareholders, all of them. It is essentially a buy out. That means you have to sell at a price that the shareholders accept. Which means paying more than the marketshare.

For Apple and Google, you'd need a massive amount of money to buy the companies. Dell found it by taking his money plus taking billions in private equity partners and can creditors. One thing that helped Dell was that it was a pretty cheap company. Trading at less than 10 P to E.

Plus Wall Street trusts Apple and Google. There isn't a huge gain by going private.
Loading an x64 register, how hard could it be?
I don't think the effort needed for this is worth it. Most scientists even ones who code, don't even know what bootstrap binaries are.

My original point is that the complexity of dealing with differing environments and code versions, combined with the sensitivity of floating point results on the exact source code and environment, practically kills the possibility for exact reproducibility.

That's why I'm claiming that a better goal is approximate reproducibility.
> One last comment: Not all businesses are conducive to a pay per use or pay per user model. For some things, that simply does not work. This is exactly why advertising has been used for decades by content providers, even before there was an Internet.

I'm not sure why anyone would care that these businesses don't work. Why are we expected to prop up businesses that don't work?
When building content management systems, we've taken a approach similar to this to keep URLs constant when names of articles, posts, objects might get changed by an site admin. The first time I noticed this approach was Trello.

Here's an example trello URL:
https://trello.com/x/1234567/203-make-the-buttons-bigger

If you change the name of the card, the ID (203) stays the same, but the friendly part of the URL stays the same. When directing you to the card, the system doesn't care past the ID.
That's awesome, the editors spitting in the face of their readers and the graves of their ancestors. It puts a clear point on what's wrong the Times, though: rich kid rambligs in a classic font.
This talk was great, especially its focus on non-parametric techniques. A lot of people are mislead by the traditional statistics approach, where it looks like stats is about memorizing a relatively short list of (really scary) formulas that let you compute one or another thing. People do not think about how these formulas come about, and the simple ideas behind them.

On the other hand, I think there is not enough written about how to do statistics with real, large, complex data sets. I tried to write something like this (https://pavpanchekha.com/blog/stats1.html) but of course the difficulty is that investigating a complex dataset is by definition too complex to really fit into a blog post. In a large dataset, the difficulties are the how and when you make decisions about what to analyze.
How so? It's extremely trivial to make an inline script that detects if the client is blocking ad network requests, then act accordingly. Possible actions range from blowing up the page to redirecting the user away.
Ronda Rousey Gets It She Hammered the War on Marijuana During Press Conference
MRIs were certainly performed on autistic patients in order to determine that certain physical variations in brain structure are associated with autism. But if your goal is to diagnose autism, there are much cheaper (and more accurate) ways to do so, and if your goal is to treat it, the MRI results don't really inform your treatment options, so the consensus is probably that an MRI would be nothing more than an extremely expensive way to get a vague confirmation of the diagnosis.

(Of course, if the author's hypothesis is correct, that may be about to change.)
It is fair to say that planes don't come crashing down much, because the FAA prohibits it. Private enterprise had a very low bar for safety, when left to its own devices.
Isn't working around things to make them work for you exactly what the essence of hacking is?

Plus, doesn't every hacker start as a script kiddie? Using something others came up with usually sparks the imagination. The next step is usually using the scripts right, followed by using the scripts extensively and finding issues, followed by making your own scripts (or improving the existing ones) to avoid these issues.

This looks pretty hackish to me.
did my thesis on this topic (at that time we were searching the lower bound of ALU needed to have them running in zero power devices)

it's interesting, NN degrade at about 6bit, and that's mostly because the transfer function become stable and the training gets stuck more often in local minimums.

we built a training methodology in two step, first you trained them in 16bit precision, finding the absolute minimum, then retrain them with 6bit precision, and the NN basically learned to cope with the precision loss on its own.

funny part is, the less bit you have, the more robust the network became, because error correcting became a normal part of its transfer function.

we couldn't make the network solution converge on 4bit however. we tried using different transfer function, but then ran out of time before getting meaningful results (Each function needs it's own back propagation adjustment and things like that take time, I'm not a mathematician :D)

We own a rural residential property near Chico, CA on top of a mesa in a fire-prone area, and the forest "management" is haphazard, combined with clueless American neighbors whom the city has to force to mow their weeds and remove fuel from their land, and you have a constant battle against stupid and/or lazy people whom don't know how to mange their land and are liabilties to everyone else. I'm often think about "accidentally" chucking a roadflare in their yard to get them with the program.

IIRC forest management changed significantly under either Bush Sr. or Clinton.

'Autism' is useful if you need a diagnostic code in order to get a kid certain types of support. It's absolutely useless as a medical diagnosis.
I don't understand the obsession with bitwise reproducibility. It seems like if your algorithm is numerically stable and valid, you can just compare multiple inexact test runs with some margin of error. Even if you hire nothing but guru-level IEEE floating point experts, a focus on bitwise reproducibility will close off a lot of opportunities to parallelize the code.

A lot of machine learning tools like random forests and neural networks inherently inject randomness. Are we just going throw up our hands and say we only use classical deterministic algorithms run in single threaded mode, because we can't think of any way to compare multiple test runs except memcmp? Because that's what I'm hearing (maybe I'm missing something).

This is mostly true, but last time I checked, Stan still couldn't sample discrete variables like BUGS can. Stan can only fit models with discrete parameters (e.g. finite mixtures) if the programmer is smart enough to integrate them out.
>Contrary to the conventional view of an American economy bubbling with innovative small companies, the reality is quite different. The rate at which new businesses have formed in the United States has slowed markedly since the late 1970s. Big Tech’s sweeping patents, standard platforms, fleets of lawyers to litigate against potential rivals and armies of lobbyists have created formidable barriers to new entrants.

Eh... nice try on that stolen base. The internet, which is what drives "big tech", wasn't really an economic force until the mid '90s. If business formation has slowed since the '70s it's more likely to be a result of rise of the regulatory state. You can't do anything without a permit any more, something that wasn't true in 1970.

It's stunning to think that we know enough biology to make a good guess at the entire billion-year history of life itself, possibly the history of all life in the universe. In one sense, producing this tree is a major goal of biology, a battle fought by Linneus, Mendel, Darwin, and thousands of biologists in the centuries between.
In a way we're arguing past each other: you're saying that approximate reproducibility is realistically the best scientists can do with today's toolchains. I'm saying that programmer's writing tomorrow's toolchains should do better. It seems at least possible that we could both be right :-)

Xvideos uses the same technique to good effect as well. All of their videos links follow the format:

www xvideos com/videoNNNNNNN/description_of_activity_which_can_be_easily_updated (NSFW)

I wanted to mention a mystery concerning Xvideos. Here's a business that is very much in-your-face (i.e. it is not a defense contractor or an organization that wants to be discreet), but its ownership is totally unknown.

I researched it. There are literally zero articles or information about who owns it. No interviews with the founders. Nothing. I haven't been able to even figure out what country it's based in.

Somewhere out there is a very rich person whose family and friends probably don't realize that he founded a major Internet business.

Yes, a major Internet business: they have several million videos (far more than competing "tube" sites), hundreds or thousands of fast servers, and an Alexa rank of 47 which is higher than imdb.com and only a couple steps below microsoft.com.

But in this age of little privacy, they've managed to be super private.
I'm white and I got suspended because people on the hockey team who had been bullying me for years alleged I owned books containing bomb-making instructions. It took my mom arguing my case in a special meeting with the principal, a rep from the district, and a guidance counselor to get claims of anti-semetism removed from my record (because I was and am an atheist and had expressed the viewpoint that religion was a social ill).

If I had brought to school what Ahmed did, I probably would have been dropped with two to the chest and one in the head by the school cop and then double-tapped on the ground. Maybe I just would have been tased, handcuffed, arrested, and recommended for expulsion as per the school district's zero tolerance policy, but since I had long hair and wore lots of black clothing at the time my school probably regarded me as the most likely Columbine copycat candidate and would have reacted appropriately.

Ironically, this was in an affluent area with plenty of wealthy foreigners living in the US. There were a few Muslim students at my school, and aside from juvenile idiots I'm sure there was almost no islamophobia, and certainly none on the institutional level. But everyone has stereotypes they fear, and if you fall into that as a child in the school system god help you.

I really wish developers today (in the 2000s, for Christ's sake) didn't have to deal with such a horrible UI.

The Unix Hater's Hanbook says it well:
"The original Unix solved a problem and solved it well, as did the Roman
numeral system, the mercury treatment for syphilis, and carbon paper. And like those technologies, Unix, too, rightfully belongs to history. It was
developed for a machine with little memory, tiny disks, no graphics, no
networking, and no power."

Bu since wee seem to be stuck with Unix, I guess we need any guidance we can get.

> You're saying that you define "advertisements" as the things you don't like.

No, I'm saying that talking about the definition of "advertisements" as if you're too dense to understand what people mean when they say "advertisements" in this context is a distraction.

I'm not arguing for any definition of "advertisement". I don't believe words have inherent meanings. I believe that people should try to understand what people are saying instead of being pedantic.

> Google ads sometimes miss the mark, but often are for exactly what I'm searching for. Why would I condemn them along with penis enlargement ads?

Because they're a failure of Google to provide a good service. If they're exactly what you're searching for, they should be the top search result. And if I come to Google's page looking for good search results, I definitely don't want to see an ad where I would expect to see the top search result.

> My point is that advertising is a spectrum, and you can't just "block all ads" without throwing out the good as well. And a related point is that some advertising is good.

I disagree. There is no situation where I want to be manipulated into buying a service or product I didn't specifically come to a page for. There are no good ads.

> What I was responding to was the allegation that all advertising is bad. And until you're willing to pay for the content you create, that advertising is necessary to pay for it.

All advertising is bad. I'm willing to pay for the content I consume (and I do in many cases where it's possible to do so).
I'm the Director of Engineering at Udacity and wanted to clarify a couple things: All of our content is available at no cost. It's an important manifestation of one of our most important core values—that education is available to everyone. What we charge for are services. Students enrolled in Nanodegree Programs have access to coaches, a massive worldwide network of code reviewers, certification, job placement and much, much more.

We work hard to help Nanodegree Program students that are looking for jobs in tech get them. For example, one of the best parts of my job is doing mock interviews. Folks on the engineering team volunteer to give a representative tech industry interview to a soon-to-be-graduate and then give them detailed feedback on how they could improve. Hearing back from these students a few weeks later that they got a job at Nest or Google or wherever is one of the most satisfying things I've experienced in my career, and everyone on the team who's done it feels the same.

Finally, we really do think our graduates are ready for jobs. So much so that we've hired two of them as full-time SWEs onto the small engineering team at Udacity. This has worked out incredibly well—these are smart, effective engineers that I'd put up against any traditional school's CS grads. We'll be hiring more of them, and we hear from companies that have hired our graduates that they'll be doing the same.
And you're completely wrong.
