A couple of advices for you then.

Unless you’re planning to do reverse engineering, or planning to work on a compiler, learning assembler is mostly pointless.
In most cases, real-world algorithms contain both vector code in the inner loops, and scalar code everywhere else. When coding assembler you need to use it for both, and assembler ain’t exactly user-friendly.
Using C or C++ language with SSE intrinsics is the way to go.
All modern compilers support them.

Intel’s documentation is the best so far, but there’s no offline searchable version.
I’ve created one: https://github.com/Const-me/IntelIntrinsics/releases

Memory layout is a king. You need to keep the input and output data SSE-friendly: aligned, dense, sequential access patterns are preferred. This could mean you need to [re]design some parts of your software specifically for SSE.

There’re multiple generations of hardware. When writing manually-vectorized code, the compiler won’t tell you what CPUs it’ll run on. SSE2 is the most compatible. Here’s some statistics about Windows users: http://store.steampowered.com/hwsurvey/ click on “Other settings”

Funny, Just discovered and bought it yesterday :-) Seems like a very good book just by glancing at contents as well as the way the material is presented and taught. Noticed the Amazon reviews are also very good.
And by the final saturation point the value should be known well enough (and the other infrastructure aspects I mentioned will be in place) that lost coins will be a negligible concern. An expansion of "exchanges" will help a lot as then you no longer have problems with abandoned wallets as the funds themselves can be used elsewhere until the owner decides to withdraw.

Love your point about hawking. I treat that as pure entertainment but since the general population treats hawking with high regard (well deserved) his opinions about things he doesn't know much about also carry weight in shaping public perception.

As far as speculating on how scary an AI driven future can be, a filmmaker in the 60s or a high school student today can do as compelling a job as Hawking.

> Either they modified their algorithm in a way that affected values retroactively, or they're trying to disguise the fact that their previous Zestimates were way off.

Probably the latter. Although, it could be that the data points are calculated on the fly or starting from some arbitrary value.

Then again, since it's shady to begin with, disguising their mistakes wouldn't surprise me.
I don't have an opinion on whether zestimates are accurate. But this blog post has 9 samples from only 3 cities. And the author seems to be making claims based on that. This is a lame "thought leadership" post as a subtle ad for his company.

At least give me 10-20 homes in each of 10-20 cities if you are trying to convince me of something systematic.
Maybe they also weight you when enter and leave the store. They can then cross check your weight with the weight of the items you have bought.

NYC has stood its ground. They haven't given up anything here. All they said is that they wouldn't try to fine Airbnb itself under this law, which they have stated was not their intention from the beginning (as to do so would possibly violate federal law anyway).

And airbnb may only be enforcing a "one host, one home" policy in the city, but the city will presumably still go after all "entire place" listings.
Well, yes, but as long as you use a nonce and sufficiently large hash you can make the probability of brute forcing the hash arbitrarily close to zero. So it works well enough :)
Who is doing these "formal assessments"? Are these broker price opinions (performed by a real estate broker)? It seems very odd they would use Zillow data instead of the MLS to find comps.
Mining bitcoin is basically the process of spamming a loop of incrementing a nonce and calculating SHA-256, until you hit a hash that's lower than a certain threshold.

In the beginning, people used general-purpose CPUs for this, but it's the sort of embarrassingly parallel problem that GPUs are great at, so GPU mining rapidly outstripped anything that a CPU could do. These days, even GPUs are outclassed by ASICs designed specifically for mining. The amount of bitcoin you'd get by mining with a CPU would be minute and, worse still, would actually be a net negative, once you factor in the power bill to keep that CPU running. The ASICs are just too power-efficient for anything else to compete.
I bought a home last year, and each realtor I talked to brought up how terrible Zillow was before I ever mentioned it. If you look at the WaPo article all the comments are by other realtors, so I'd take those comments with a grain of salt. Oddly, my mortgage guy never looked at Zillow (that I saw) for figuring out values, so shrug.

I'm sure the data is inaccurate, but it's somewhere to start the conversation and let people feel like they have some power in the process of buying and selling homes.

And as people like to say about Uber, realtors are welcome to make a competing site that's as free and easy to use.
That's no change. Between customer loyalty cards and the easy ability to tie purchases to credit cards, if they wanted to do that they already could.

I'm not sure it buys them anything, though. That's a very noisy signal against the loud-and-clear signal of what the measurements say when you come in to the doctor. Who cares what your shopping habits say when you come in with high blood pressure and morbid obesity, or good blood pressure and normal weight?

The change is specifically in in-store behavior. And even that's more because Amazon has the money and skillset to fund the software; the supermarkets already have the data in the sense that they have the video streams, they just don't have the money to fund people running beyond-cutting-edge vision research on it to get that level of analysis.

No way I could see that happening. I mean, they might conceivably decide to fold the group into Google Research rather than keep the DeepMind name, but I doubt they'd do even that due to the name recognition that DeepMind has garnered even among the general public.

The idea that they'd take the people and put them to work making Blogger better or something? Not a chance. AI research is pretty much Google's core function. They'd no more break up that functional area than Apple would take Jonny Ive's team and put them answering support calls.
Better question is "how bad are the compared to those of professional appraisers who look at half a dozen comprables?" An even more important question is "how biased (based on who is paying) are those professional appraisers?"

There was a Scientific America article that discussed something similar but the major point of the article was that there will more likely be habitable planets in the future. That is the universe is still in its early days of habitable planets/zones.

I read the article casually before going to bed and can't recall that many of the details.

I'll try to find the article and append a link (I believe the article even referenced the same study).

On Haskell you don't even get much choice. The community is so biased towards qualified importing that most modules clash, and you'd need some incredible stretching to use them unqualified.

As most things in Haskell, it tends to work greatly. The usual problems go away due to some combination of Haskell's features and the main problems are things you wouldn't think about.

Actually, this is somewhat surprising. It's taking what many, MANY data scientists and analysts are actually using day-to-day and making it point-and-click to start in the cloud.

You can set these things up in AWS and GCE, but it requires a lot more work. Here is my top google hit for setting things up on AWS, from a relatively recent and maintained repository: https://gist.github.com/iamatypeofwalrus/5183133

Many data scientists just run their notebooks locally. Few have the luxury of Data Science Engineers on hand to help them through the complex world of provisioning and maintaining servers, even in this canned AWS world where spark clusters unfold themselves in EMR.

Azure is absolutely full of "here is a canned solution for _insert common engineer task with open source focus here_" buttons and it's really quite great as a result.

Also: Azure is doing a very good job of making it difficult to have a default-insecure instance. You don't make choices about encryption-at-rest, for example. That's forced on you. There is a lot more tooling around sharing accounts and giving users minimal ACLs rather than just doing the simple thing in AWS or GCE and giving out power user accounts.

It's simple stuff, of course, but this simple stuff is the simple stuff AWS has elected not to do, so...
What happens when you don't have enough money available to Amazon to cover all the things you grabbed? Do they give you a window to return items before banning you from the store and/or notifying police?
If there's two things I get uneasy about, it's (1) giving up privacy in a whole new category of being filmed/monitored/tracked and (2) being guided into behaviors that encourage me to consume more and consume more casually.
I doubt Amazon is in the business of selling your data to insurance companies.
Ask HN: Large client demands our code be given to a trustee
We're a small startup, providing a whitelabel SaaS. A large potential client demanded that a copy of our source code would be entrusted to a third party (attorney) to be released to them only in case our company goes belly up.

We have reservations about code not being under our control.

Has anyone experienced something similar? What are the risks? Could they be mitigated?
Not a dumb question at all! You can create cycles in Haskell thanks to lazy evaluation. I can make a circular list in Haskell with the following:

x :: [Int]

x = 0 : y

y :: [Int]

y = 1 : x

And thus we have a circular list with the elements 0 and 1. It's technically an infinite-length list with 0 and 1 repeating forever, but Haskell will represent this in memory as a circular list.

Mostly interference, even by our own equip. We operated in an area that has multiple other WISPs and the last network step to our customers was entirely 5ghz, so almost all bands all across our network had at least some interference. And with the competition we could not ask to please not use 50mhz channels everywhere even when unnecessary.

I guess I should have said that right away. If interference or false DFS positives aren't an issue, they're excellent radios and with the 34dbi antenna dish UBNT offer you can potentially bridge unbelievable distances.

For LOS Backhauls I'd always go for the AF24HD unless the steep price is an issue. Then again, the license for 18ghz radios alone costs more in Germany and tbh I haven't seen any interference ever with 24ghz, even if it is a free band.

You are shocked big chains aren't doing this? What big chain has a robust R&D department working on image recognition? The profit margins at major grocery stores won't support anything like this.
I don't think the system works like that.

From my first quick take of the video, the app+turnstyle is used to identify you to the store. The video system then tracks your position as you walk around.

When you walk out, the items are recognized and tallied by a large RFID sweep. Funneling you back out through a turnstyle makes sure the vision system knows it's you. Notice that you don't need to barcode yourself on the way out, and the exit system is phone agnostic (it's not checking for an NFC or Apple Pay tag or anything).

The whole "tracking individual items as they come on and off the shelves" task is a very complex thing. But tracking bodies as they walk around a 1,500 square foot room isn't that hard.
"I'm absolutely shocked big chains aren't doing this already."

They don't have the money. It's a very competitive business and margins are not high enough to be doing that level of cutting-edge computer science research.

I've seen them try just to build software that allows you to shop from home and get it delivered either curbside or to your home. They can. But in my opinion, it's also clearly at the limit of their capability, and with all due respect to the programmers involved, also clearly just barely staffed adequately.
> What's puzzling is that they also bumped up the historical Zestimates

There are two things a "historical estimate" could mean:

1) What did Zillow say the value was on day X?

2) What does Zillow now think the value was on day X?

You and others seem to be thinking of (1), but I think Zillow actually is doing (2). Since the goal is to figure out what the house is worth and how its value has changed, I think (2) is actually the right metric here.

That's a nice boilerplate comment that could be applied to any open source project, but the reality is that Ivy is essentially abandonware.

At one point recently, I did a search and couldn't find any committer activity of any kind (code, mailing list messages, JIRA updates) for the better part of a year. And it's not like the project is "stable" or "complete" either -- users are constantly making posts about serious bugs that go unanswered, because there's nobody active who has the knowledge to investigate or fix them. (I've run into a couple of these myself.)

EDIT: Just took another look to see if anything had changed. The good news is that a couple of very minor bugfixes were committed in November, amounting to a grand total of 14 lines of code changed. There have been no other commits in the past 12 months, and the last time one of the committers responded to a question on the mailing list was March 2015.

> are non-shoplifters going to be turned into shoplifters without a checkout?

One could respond that you can never truly shop lift if you follow the rules.

First, you have to check in when you enter. Second, they tell you to grab and go.

As long as you don't try to be malicious about it, then it's on Amazon to figure out what to charge you for. If they fail to see something, that's on them.
I think there are bigger problems, like how they implicitly assume everyone is a thief and are will to damage usability for everyone because that assumption.

That stupid scale isn't going to stop any shoplifter, but it does inconvenience me every time.

Trying to classify dependencies as "common" or "non-common" is a big design mistake. It's an insufficient solution done because flatpak can't actually capture the full dependency graph of an application. If it could, then common dependencies would be implicit (shared nodes on the graph) and no bundling of supposedly non-common components would be necessary. Examples of this problem solved correctly are Nix and GNU Guix.
Thanks for sharing! Never really used Bitcoin, but this was pretty helpful.
Your last thought is key. Medical diagnosis demands extremely high precision as well as 'judgement' because one little deviation can be highly correlated with something serious. And there can be several of these deviations in different places. Sometimes a doctor notices something is off while looking at something else. It's not easy to model out all these while keeping up with the changing knowledge in the field and still avoiding false negatives.
