I'm interested in this, maybe as an investor too. I like the idea of ways to enhance the 'buy and hold cheap houses' investment concept. I also have one or two ideas on how to do that. Send me a message if you go ahead with it. My email is in my profile.
I was wondering the same. Because they're a middle man perhaps they can take in cash and deposit it into a normal bank account?
We are afraid that when we nanotexture the floor of a shower (or apply a polymer film on top of the tile) that the surface will become a hazard to someone trying to take a shower

You mean because it's slippery? If so, don't worry about it. My shower floor (plastic, not tile) has ~millimeter-sized bumps that make it not slippery at all.

This is really cool! It sounds like you're trying to determine whether you can identify AF out of data that's complicated by poor recording quality and regular activity? Is your longer term goal/business model to use this as a diagnostic tool (i.e. replace a Holter monitor)?

And since you offered to answer questions, I have a somewhat niche one. I'm an MD/PhD student doing my research in computational electrophysiological modeling, and I'm getting interested in the idea of using machine learning in medicine, specifically in signals analysis (i.e. EKG), and in time-series analysis (like heart rate variability). I'm teaching myself machine learning via a fantastic UW Coursera series that covers the basics (regression, classification, clustering, etc) with good mathematical rigor, but I'm not really sure where to go from there. What techniques would you suggest I look at? Would learning something like TensorFlow (I know Google has put out a course on Udacity) be a good idea? Obviously at some point, I just need to find some small projects to jump in on, but I want to build a decent skillset first if I can. Any thoughts would be appreciated!

So it can't be used without a phone and phone number? Like most people I have those items - but only one of each. Good enough for standard chats with family and friends (which I currently use iMessage for), but on occasion I'd rather be pseudonymous, and it's precisely then that I need secure communications the most. Right now I have no idea what instant messaging software to trust, so I was hoping I could use Signal over Tor for this purpose, but I guess not.
Another interesting thing to datamine might be number of comments positive/negative about certain companies followed by the results. Certain people will be accurate more often than not, maybe in general or certain niches. Then, new ideas receiving comments can be scanned to see if any of those people are making similar points. Might become one factor among others in the VC scoring process for what gets funded.

FWIW I used TypeScript in anger with React, and hated it so much I rewrote all the React code in regular JavaScript. TypeScript and React, IMO, are a poor fit.

To be clear: I do like TypeScript and use it almost exclusively on the server, so this isn't a case of me "not liking TypeScript". It's the combination of the two. Basically, all of the stuff I did to keep TypeScript happy when using React was worthless overhead and brought nothing but pain, warping the codebase horribly. The JavaScript version with React was smaller, lighter, and had way less cognitive overhead. YMMV.

define 'actually round'

it had patches, and these were a not very important technical first, because an artist could create the same geometry in a number of ways and get the same end result. from a usability perspective of level editors though, it saved the environment artist a considerable amount of time, effort and risk of mistakes.

the patches were cubic bezier patches of fixed subdivision. other game engines improved on this in short order to have dynamic subdivision/lod based on distance without cracks and more complicated patch types (e.g. you can never make a sphere with quake 3's patches)... whereas keeping the subdivisions fixed means that cracks are trivial to avoid.

i believe that quake 3/id tech 3 did not solve this even in later iterations... it was more another tool to add fixed, un-lod-ed triangles to the environment mesh, with an added caveat that they didn't seal the convex hulls describing the pvs and inside/outside or get used to provide planes to split the bsp.
The thing about Detroit houses is that they sell for much lower than they are assessed for, so buyers would be paying taxes that are very high compared to the selling price.

ALWAYS spend time with your future boss prior to accepting.

Not always possible. For example, at a lot of the larger technology companies, you'll be hired (on paper) by a group manager, who'll then assign you to one of the handful of teams he or she is in charge of. And that's leaving aside stuff like what Facebook does, where you spend 6 weeks "in training" before being assigned to your actual team. Or Google's policy of not informing people what teams they're being hired for.

In that situation, my the best thing to ask about is the transfer policy. A bad team is bearable for a finite period of time, if you know there's a fixed path to getting out.
Not parent, just my own negative views on electron:

1. Massive download for a simple app. 37M is a lot of data.
2. Massive download for every simple app. It would go a long way if every electron app didn't have pull in a full 37M, and could share a set of common libraries. n*37M is a lot of data, and this is one strong reason I like this Signal Desktop release.
3. Battery unfriendliness. Even when idle, every Electron app does a lot under the hood that isn't even related to the app itself. This is the cruft of having a full web browser and an advanced JS VM, but it is a cruft regardless, and it is very disheartening when reduces a ten hour battery life to six hours.

From http://www.catb.org/jargon/html/koans.html#id3141241

In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6.

“What are you doing?”, asked Minsky.

“I am training a randomly wired neural net to play Tic-Tac-Toe” Sussman replied.

“Why is the net wired randomly?”, asked Minsky.

“I do not want it to have any preconceptions of how to play”, Sussman said.

Minsky then shut his eyes.

“Why do you close your eyes?”, Sussman asked his teacher.

“So that the room will be empty.”

At that moment, Sussman was enlightened.
Ah, reddit.
Only if the training set was the artists thoughts and feelings. And the model was his nervous system and body mechanics. The images alone are not enough data to truly mimick the next painting he would have produced. It's an average of the existing work.

Do you happen to know what the thinking is behind having all the changes in one commit? I imagine it would make for a much neater master branch.
Recognizing that the spirit of your comment is about the utility of Wikipedian descriptions in general (I agree!), I thought I'd build out some of these concepts in case someone similarly frustrated also happens to be curious about them.

"Plant" is a legacy term referring to the device or system acting on the state you're trying to control. Sticking with thermostats, the plant is the heating element.

A straightforward way to think of hysteresis is that the output depends on the history of the input. A simple example of hysteresis in a temperature controller would be to turn off heat if the temperature rises above threshold A, but only turn on heat if the temperature falls below threshold B.

"These controllers may be realized in terms of any element that provides hysteresis" -- This is indeed awkward phrasing, since it could be read as though the property of hysteresis is fundamental to create a bang-bang controller. In fact, using hysteresis is "just" a best practice. Strictly speaking, you could make a hot water heater that turns heat on and off based on a single hard temperature threshold as measured by a thermometer, and it would work. However, any noise in the system will make the output jittery and cause unnecessary cycles. Having a "heat off" threshold higher than the "heat on" threshold makes for smoother transitions.
Yes, I know, and agree.
Thank you. A lot more information in that video than in the article. Looks like it was half human and half algorithm. Still very interesting way of making imitation paintings.

I may have been told wrong, but I'm sure I recall being told that some consumer heart rate monitors (the kind with a chest strap) are approximately as accurate as what's used in a doctor's office. Now something that doesn't use a chest strap... I don't know. Probably those are less accurate? And/or maybe I'm the one who's been misled.

We have a cluster of codechecker servers of the above type, which share the load of incoming queries. On each, sandboxing is via a chroot-based system. Programs get a fixed amount of memory/time.

Re: the codechecker keyfile - we're looking into this, as I'm not an android expert - but quick searching tells me this is used to sign apks. Our codechecker supports android builds, so that's probably what this is used for. This key is not used to sign anything official (like throwaway id_rsa you create when needed). Again, I'm not the expert on this and I'll add a confirmation here shortly.

That said, if anyone finds something a vulnerability/way out of the sandbox, please shoot me a mail (anil @ hackerrank) if you'd like to do a private disclosure.

elephants do really good abstract impressionism as long as you tell them when to stop.

Not to say that rembrandt = abstract impressionism. Still, the humans tagging features is kind of a copout. The 'grain of salt' for these projects is to look at the variation of outputs when you tweak the model inputs. In this case it's going to be a head with oil paint texture 9 times out of 10 (and the tenth will be cecilia jimenez 'I fix').

It won't be long until a computer can 'participate' in a genre and really contribute to art. This project, while cool, isn't there yet.
Do you have statistical evidence to support your claim regarding serial discontentment?
Thanks for sharing it seems like a sentiment shared by a a lot of people
Don't ask the interviewers what they hate about their jobs. That's easy, everyone hates their job. The best advice here is you should find someplace willing to give you a small token project to work on. Find out for yourself if you hate the place in that period of time.
I think the goal of the project was to make a painting that is statistically indistinguishable from his other paintings. Another painter painting in his style would still inject some of their own style and technique into it. If you looked closely or took statistics from two painters trying to mimic the same style, you would be able to distinguish them.

Here they went to great lengths to try to make it very accurate. Everything from the shape of eyes and faces and the patterns of brush strokes.

tl;dr: the financial industry is distasteful.

i understand what is being said here. i don't think it is revelatory.

on the other hand this article just adds another small contribution to my strong distaste for the practices of the financial industry overall.

investing money into funds to make more money seems great at first glance, but once you dig into the details and realise the number of people involved taking their cut, how many companies are effectively running off of weird loans through 'ownership', and how many piles of assets are owned by people as a mechanism to make more money... its all very distasteful to me. :(

then again, i don't like investment. i don't want it for my own company. it looks like a way to become beholden to others and introduce a risk of spending more money than you actually have.
Looking forward to this, will be really interested to see how it turns out!

The Brain That Wasn't Supposed to Heal
No one sane is asking for exact estimates … It's not a deceptive or inefficient practice, it's managing uncertainty.

Part of the issue is that the asking for estimates ends up getting turned into exacting time requirements as an attempt to control and manage uncertainty. And often, many of the people who turn estimates into requirements are, arguably, insane, because they are trying to manage the uncertainty in the wrong way.
I was a little disappointed in this. In his strange little book "Imaginary Magnitude", Stanislaw Lem imagined an entire branch of literature, "bitistics". This is the literature produced by AIs, essentially. The first such work is "The Girl", Dostoevsky's final work that was never actually written.

I wanted MSFT's computer to do the same thing that Lem's bitistic writers did: visual the entire corpus of some artist's work, and "fill in the holes" with material that the artist never actually completed.

But alas, MSFT did some of the usual statistical jiggery pokey and decided on a white guy with big pores and a hat, wearing a ruffled collar. Then, they got some other tools to make the painting. Maybe Rembrandt would have painted it, maybe not. We won't know until AI is as good as Lem posited it could get.
i think that this is a gimmick rather than a reason.

languages that have their own tools built with themselves are cool... but it has zero practical value imo. the number of C/C++ programmers interested in Go and capable of contributing meaningfully far outweighs the number of programmers who do not know C/C++ and are interested in Go

>Please discuss why are you satisfied about it?

I really like Hack, although I am learning some of the assumptions I had about the way types work seem not to be correct, and I'm debugging through nano which is annoying. I don't like that it doesn't support ArrayAccess, but things like shapes and immutable types more than make up for it.

Teaching myself game programming at the low-but-not-bare-metal level of C++ and SDL is satisfying because of the problem solving challenges involved. I kind of know in the back of my mind that I'll probably never come up with a game anyone wants to play, though.
What is exactly your problem with TSX? I've been using TSX for a while so maybe I can help. The only thing that TypeScript really adds to JSX is component parameter validation, which is quite neat to be honest.
Hmm. That's interesting. It's closer to the other commenters definition. I like how they straight up call it "assume" for accuracy. :)

Note: This discussion on an "obvious" problem shows how deep the rabbit hole can go in our field in even the simplest thing. Kind of ridiculous and fun at same time haha.

Because they make changes to the core.

LLVM based toolchains compile hairy native code faster than any other tools i've seen... GCC, MS, Intel compilers for C/C++ are all very slow by comparison and the benefits are marginal (but still valuable).

for JIT or dynamic stuff LLVM is a poor fit. it doesn't surprise me that JS VMs do better with JS than LLVM, because there is no actual compilation involved as such - its a completely different class of problem, and its just not designed for that kind of language and environment, which is highly derivative, dynamically late binding and built in many layers, the vast majority of which are themselves compiled with C/C++ toolchains like Clang/LLVM, GCC or the MS compiler from necessity...

quoting that first article you link: "it isn’t specifically designed for the optimization challenges of dynamic languages like JavaScript."
