I love your project but I totally detest your landing page with the huge animated panels that sit there eating up cycles that could be used for something better. I'm sure it's great for conversion and all that but that doesn't stop me from being irritated.

If the course is free and you're doing this to improve the world what's the point of using such tactics? At least shut down the rotation after one or two iterations.
I tend to see this sort of thing as not a failure of competitive markets but an consequence of them working too well. With perfect competition everyone ends up with close to zero margins. One way to avoid this problem is to make a high end product for a while, gain a good reputation and then cost reduce the heck out of the product. Then you can charge for the high end product while only paying to make the absolute cheapest thing that sort of looks like the original product. You get to actually make some money for a while.

Professional marketers apparently refer to this sort of manoeuvre as "harvesting the brand".

Why vertical farming specifically?

Ethnic Chinese investor, China focused. China has removed a lot of arable land recently for urban development, people are urbanizing at the fastest pace in human history, and food prices are rising quite rapidly.

Your comments are logical for the US and your project sounds interesting. From what I understand EU agriculture is a sort of middle-ground, with smaller-scale automation.
He has about twenty million weekly listeners.
After reading the comments, and seeing what others have gone through, and generally speaking I'm not the biggest fan of PayPal. I gotta say: +1 to stripe! https://stripe.com/

They are fantastic to work with, and its super easy to get setup with them. Hats off!
I'd just like to take a moment to acknowledge the author for their excellent "Don't look under the rug" section. Amazing.. I wish every article had information like that.
Where was the ACLU when this policy was in place for 96% of the Obama Administration? The FCC just changed it a week before the last election.

Not to mention that that increase in illegal market usage gives more fuel to the fire for people to believe or be led to believe that more of the same restrictions are necessary, a self fulfilling prophecy almost. Of course its not that simple, but seems to be what happens.
On the other hand cars have gotten way better. I wonder why?

I remember in 1990s it would be somewhat remarkable to see a car from the 70s. But in the 2010s it's pretty common to see cars from the 90s.

And the paint in my nine year old car basically looks brand new.
The German appliance manufacturer Miele has been making quality long-lasting products for decades. They are rather in the upper price segment, but not without reason in Germany they say, if some appliance breaks down: "Next time you better buy it from Miele.".
thats the same link as the submission you are commenting on...?
The initial marketing blitz was all about the performance of the memory itself. Putting it in a NVMe SSD hanging off the PCIe bus instead of directly on the CPU's memory controller takes away most of the performance benefit. Intel's hit their goals for density, and missed their goals for endurance.
Fact is there are no good old days, in the gatekeeper era only a select few got to BS, now that BS vending is widespread. The Networks act certain way because remember they use the "airwaves" permitted to them by the public for common good. That is it.

As some one said, If Trump were to walk on Water, NYT would report, Trump cannot swim. We already know no positive headline would come out of NYT for a Republican president, so is it really "highly" credible? If we think these are the worst of the times, then we really do not have depth about what happened in the past.

The Press wants good old days, where they were demi-gods with access to contacts and info, and in this information age that bar has been lowered and Facebook is eating their "attention" lunch.

If looked objectively NYT is just being a whinny grumpy old man.

What does his "outrageous harassment" have to do with his ignorance towards security?

I agree that he should've used SHA-2 or better yet, have made the hash algorithm modular, but what does your quote add to the discussion?
"Raising interest rates isn't poison."

Higher interest rates are intended to slow down the economy by making borrowing harder.

"Also, at the moment deflation isn't a bigger risk. It says right in the article inflation is slowly rising, not falling."

1.74% is very low, and on the wrong side of target inflation. ~3% inflation is considered historic, and we are no where close to getting there. not even a little bit. if that anemic .03 growth went even a smidgen on the wrong side of 0, that would be bad. so yeah, deflation is still a bigger risk.

But, in any case, that's in the cryptographic realm.

Git hashes aren't digital signatures for cryptographic authenticity.
I immediately looked at the length of this commit's hash to see if it was longer than 40 hex chars -- but no, it's just an SHA-1. It would have been cool if somehow the hash of this commit that added new hashes was a new hash.

Slightly similar: for a while I've wanted to recreate just enough of git's functionality to commit and push to GitHub. My guess is the commit part would be pretty trivial (as git's object and tree model is so simple) but the push/network/remote part a bunch harder.
This guy get's absolutely zero sympathy from me when he starts his rant, complaining in a condescending tone.

"It sure is a weekend. It is probably nice and cozy for most of you over there in Chicago, enjoying a ball game, visiting friends and family, grilling that steak, feeling good about yourself."

It is funny how people like this want to blame and paint American corporations as evil, yet they build their business on startups and companies that could have only been founded and successful here in the US. They hope and dream of making it to Silicon Valley, raising money from US investors. It is total hypocrisy. Don't like it, why don't you use only Serbian companies, banks, and investors to power your startup? Oh that's right...
Most of the world can't use Stripe.
Also, on average people move houses every 7 years in the US (give or take based on age) and it is typical for the appliances to stay with the house. This means the original owner/buyer is pretty unlikely to see the appliance fail before they sell the house. The next owner might, but will buy a new one and then move before it fails. Repeat...
Occam's razor goes on a different path if you know a little bit about the guts of the product.

The difference between a top 1% appliance and an average appliance is probably less than $10 of materials and $5 in labor.
This seems to be breaking the YC 'golden rule' which I think is 'do something useful'.

AI is an approach, it's not a solution.

I think AI is going to make it's way into 'everything' but rather incrementally.

I'm weary that there will be a lot of 'pure AI' type companies around.

Surely, there'll be a few that are 'AI focused' ... but it's all so techie and not so much 'market' or 'solution' oriented it leaves me a little skeptical.

AirBnB, Stripe, Zenefits, Instacart, Docker, Mixpanel - all big YC companies focusing on solutions - I can barely see how AI would apply to any of them, other than maybe some incremental improvements on things like 'fraud detection' or what not. Ok, maybe some marketing conversion.

No doubt YC is making a good call here because they want to reap the rewards of all the resulting M&A activity, which I think will be a boon ...

But it's interesting nontheless.
Non-firstworld problems:

I've had this question for a while: do we know there are only 2-3 zones per region, or might there be 10-20 and, for example, my zone 'a' is your zone 'c', and neither of us has access to the other's zone 'b' (yours too old/loaded to be assigned to me; mine too new for you)?
The author operates from the assumption that keeping rates low is stimulative. While true in many and most circustamnces, the Fed took rates to zero on an emergency basis in the 2007-2009 crisis. While originally stimulative over time the evidence that zero rates are providing stimulus is weak in fact it's likely that the harm it does to pensioners, savers and others dependent on the debt markets is not only anti stimulative- it may set us up for a new crisis. In short, the piece is done by someone with no econoic training and super prone to grandstanding and the piece feels exactly like that.
Maximizing profits also involves making products at the price points customers want. If customers don't want to pay for 50 year appliances, why should they make one?
AI works. Chinese medicine is mostly not scientifically validated, though it may have some other merits.
He's very clearly talking about Braintree, which is based in Chicago, not about American corporations in general.
When appliances are out of date in ten years because new electronics provide better features, why should customers or makers spend extra to get them to last longer?
Good luck finding modern electronic parts that will be supported for 50 years.

Also, seriously, you see so many people scoffing at the idea of supporting anything for any length of time. It is just the engineering mentality now-a-days; nobody wants to work on anything "old". Can you imagine trying to hire someone to maintain the software/electronics for appliances in 5 years much less 50?
Is this literally everyone's business plan now? Collect data, ignore sales.

> The article linked here says "3D XPoint has about one thousandth the latency of NAND flash" but I don't see any actual evidence for that. The paragraph that says it is followed by a link to actual specs for a "3D XPoint" device, saying: "the Intel flash SSD has a 20-microsecond latency for any read or write operation, whereas the 3D XPoint drive cuts this to below 10 microseconds." which sounds to me more like a 2x latency improvement than a 1000x improvement.

Keep in mind that this first Optane product is a NVMe SSD. The latency overhead of PCIe and NVMe is usually about 4 microseconds minimum, as measured by reading from a SSD that has just been secure erased and thus doesn't have to actually touch the non-volatile memory in order to return a block full of zeros. This Optane SSD has a best-case latency that is only a few times better than the best case for NAND flash SSDs. This does not mean that the underlying 3D XPoint memory doesn't have a far bigger latency advantage when accessed directly by a capable memory controller, but 3D XPoint DIMMs will be next year.
Pardon my relative ignorance on the subject, but couldn't we take an approach in which we attempt to let the brain figure out how to interpret/send signals? I.e. find a way to take advantage of the well-established extreme plasticity of the brain, and let it figure out our interface, rather than the other way around?
I somewhat get that, but in this case i think it's in the context of the "natural world". We all know it's not just lollipops and cupcakes out there.
tl;dr no.

I literally put up something about this just this evening: https://davidgerard.co.uk/blockchain/business-bafflegab-but-...

Many blockchain schemes promise the magic of full availability of properly cleaned-up data. The actual problem in every case is cleaning up the data in the first place; the barrier that such efforts founder on, over and over, is that no industry’s players want to create such a new monopoly. The proponents’ business goal is usually to become the organisation effectively controlling the newly cleaned-up data, with a monopoly maintained by network effect.

If your big goal is cleaned-up data across multiple organisations, the approach that will get you there is creating a data schema that is so obviously and elegantly the right thing that everyone just adopts it themselves, and a regulator eventually says “hey, use this schema.” Note lack of blockchains. (This is the usual approach in computing, though even there companies routinely try to set themselves up in the role of central octopus.)

Supply chain provenance is a perennial proposed use case. e.g., Provenance, Inc. is a London startup who offer to put data about tuna catches on the Ethereum blockchain. They claim to offer supply chain transparency to all participants, and this will reveal illegal overfishing or fishing that involves human rights abuses. The actual problem turns out to be no agreement on what data to collect or what to do with it. The data would still be entered by local humans under the auspices of “trusted” local NGOs – who would be paying monthly for the necessary software – on the apparent assumption that commercial operations engaging in illegal overfishing or human rights abuses will certainly carefully document their human rights abuses in the blockchain and not have strong incentives to just lie or something, or bribe the “neutral” adjudicators, as already happens in current supply chain monitoring. The main byproduct of this sort of scheme is a monopoly for the traceability provider, i.e. Provenance.

As IBM found out after starting Hyperledger, all manner of businesses – financial institutions, beef industry, shoe brands, confectioners – don’t want to share data even with all participants in their blockchain, but only with the people the specific deal is actually with. Funnily enough. This was apparently news to them. It turns out that IBM set up an elaborate hammer design consortium without first finding out if there are nails.

The precise same considerations, goals and problems will apply in this case. In all these schemes I've seen to date (and let me assure you I've read horrible PDF whitepapers out to here), the aim of the scheme is to sell someone thousands of contracting hours by convincing them you can help them become the controlling octopus at the centre of their industry.
The author is the President of the Minneapolis Federal Reserve.
No, I didn't mean to imply that. I'd say either he is not part of the shadiness at all, or he left because someone applied pressure on him recently.

But this is just my guesswork.

I'd say the first step for you (or any new developer that comes to the project) is to document the data model. What are the tables in the DB? What data goes where? What tables change on a day to day basis, and which are "stable". Where are user accounts?

Once that is done, you should document how the system interacts with other systems. Logins? Single sign on? External APIs that the system calls? External clients that call the app?

With these things done (which might take some time to figure out), you should think about writing a HOWTO for new developers. You really don't want to be the only person working on this, it will be a lot of stress otherwise. Imagine a new developer joins tomorrow. What should they look at first?

interesting stuff, thanks for sharing!
There's no way an order of magnitude more people listen to Rush Limbaugh than read NYT. There might be more listeners than subscribers. But that's hardly an apples to apples comparison, one is free, the other costs money. Many many more people read NYT articles for free without subscribing.

Ask HN: Review my startup
Meet Sportal: https://play.google.com/store/apps/details?id=com.getsportalapp.sportal

What does it do?
It helps you find players in your locality for playing any sport you want.

Why have I developed it?
Because I myself faced the problem. Many times when I wanted play my favourite sport I found nobody to play with. Then I conducted a survey and find out that many people face this issue. So, I decided to develop a solution!

Who is it for?
For everyone who love playing sports.

How is it different from other such apps?
It is easy to use and core-feature driven. It can take you from thinking about playing a sport to scoring a nice goal or hitting an amazing six in a few minutes.
I don't think the mainstream of pragmatic Machine Learning/AI (deep neural networks, reenforcement learning, etc) is really working toward that goal. However there are some who are trying to create a "software simulation of the biological brain", Numenta being one. I think the limiting factor there is current instrumentation for use in neurological study.
If I had a dollar for every document made in Word version X that didn't display correctly in Word version Y... As an Office for Mac user, I could tell you long stories of inconsistencies (e.g. they finally fixed dropdown controls embedded in documents in the july 2016 update).

In LibreOffice defense, it is kind of difficult to implement specification, that says things "works like Word95".

In the end, these inconsistencies are not a big deal. Neither between different Office versions, nor between LO a MSO. If you want pixel-perfect layouts, use tools intended to do that (i.e. InDesign or other DTP).
> what exactly gives AI/ML the "edge"?

Backpropagation. [1]

Are you familiar with the old Polaroid instant film? [2] You took a picture and pulled it out of the camera and it developed over the next few minutes. The picture went from dark grey nothingness to the image you took, like "magic".

Anyhow, so-called "neural" networks (they are no more neural than Kermit the frog is amphibious) are basically just giant polynomials with changeable coefficients. [3] The input variables are e.g. pixels from an image, and the polynomial is solved to generate a single output value indicating that it is e.g. a cat. (But before backprop this will be uncorrelated, random, useless.)

Now this image-to-yes/no-cat function is very difficult for a human programmer to write out by hand. I mean it's so difficult that no one can do it very well at all.

But using backprogagation, and a big pile of images (some of which are cats and some of which are not) and an index of which are cats for the computer to use (humans will have had to already sort and tag the images for this to work, TANSTAAFL), you can run a simple loop to develop a "function" (in the form of coefficients for the polynomial) that can "see" cats. The "training" phase adjusts the variable coefficients until the result correlates with the tagged "catness" of the images, and then you're done. After that, you can input new images to the function and it will be able to indicate whether they depict cats or not.

The function forms out of the data+backprop like an image developing on the film, projected there by the data set.

So yeah, this AI/ML stuff lets us generate useful functions that we have no other way of generating (literally no one knows how.) It's a big deal.

I guess I just haven't needed those bells and whistles. 32 bit timers are kinda huge. And some of the peripherals on the STM are suffering from "newer ain't always better" - the CAN and I2C controllers are more complicated than they need to be, IMHO.

Edit: I can't make any useful comparison on analog peripherals since I use external ADCs, DACs, etc. more or less 100% of the time

In a large class of models of global macroeconomic growth, instantaneous output grows over time relative to the integral of past output. This plausibly explains increasing "throwaway culture".[1]

You wouldn't have wanted a computer from 1995 in the year 2000. And you probably don't want a phone from 2012 today. Well, everything is getting more like that.

Your comment is probably getting downvoted because it makes some unvalidated implied assumptions that may not be true. I would absolutely leave a position like that if I discovered that the company didn't actual have the will to do what was necessary in order to fix the problems. A year would certainly be enough time to determine that and Jeff Jones departure could just as easily be read in that way rather than a lack of leadership.

On the other hand the article also says that he doesn't really like conflict so that it may be that the very toxic culture he would need to be fixing is distasteful enough to him that he just doesn't want to deal with it. This doesn't say anything disparaging about him other than perhaps that he is sane and rational and Uber has a really big culture problem.
We're in what they call the "transition zone," meaning we have moderately cold winters and moderately hot summers. So the climate is not optimal for cool-season grass because the summer is too hot, and not optimal for warm-season grass because the winter is too cold. Generally the experts recommend tall fescue, which is a cool-season grass bred to withstand drought and hot summers. Unlike Kentucky bluegrass, which spreads with rhizomes, tall fescue tends to grow in bunches so it requires occasional overseeding to keep it thick. However, it is deeper rooted than bluegrass, gets fewer diseases, and needs less water.
For some functions, such as simple timers, one advantage mechanical might have is that it might be easier or cheaper to obtain repair parts.

A mechanical timer is likely to be a commodity part used by many different manufacturers in a variety of products.

An electronic timer is more likely to be a custom board designed by the manufacturer of the appliance you are trying to repair, possibly designed specifically for that model. There might be only one source for replacements, and they may be restricted to "authorized" service companies.
> My own repair guy told me that often the insides of different brands are IDENTICAL, changing only the brand name, door chrome and other superficial things to justify some kind of premium. This means you’ll break down just as often spending thousands more. The companies themselves are becoming lousier, it is not that they are taking your extra money to make a good product.

I have a family member who does appliance repair and he says the same thing.
I asked Stripe a question once, and they answered! Specifically and referring to the details I had described in my question. I'd never expect that from a Paypal. But like Braintree, that will probably become a thing of the past as they grow bigger.
