I believe we will (1) find some basic data structures and algorithms to do real AI.*

There's no new kind of data structure to discover, humanity has made a disjonction of all possibles.
The choice of data structure for semantic parsing is trivial, it's an hypergraph.
The debate isn't the datastructure but how to fill it correctly while keeping the same Expressivity as in the original input (natural language).
There's no reason to think we will make progress on this task beyond wishful thinking.
Only a handful of humans are working on semantic parsing, which is the real AI task.
As an engineer I find myself in this type of situation quite often - if anyone can point me to some good resources or has any advice, I'd be quite grateful:

- Some non-technical stakeholder comes to me and says "can we solve this problem with Machine Learning?" usually it's something like "there need to be two supervisors on the factory floor at all times, and I want an email alert everytime there are less than 2 supervisors for more than 20 minutes"

- I ask for some sample footage to build a prototype and get a few very poor quality videos, at a very different standard from what I see in most of these tutorials.

- I find some pre-trained model that is able to do people detection or face detection and return bounding rectangles and download it in whatever form

- After about 30 minutes of fiddling and googling errors, I run it against the sample footage

- I get about 60% accuracy - this is no good. Where do I go from here? Keep trying different models? There are all sorts of models like YOLO and SSD and RetinaNet and YOLO2 and YOLO3.

- At some point I try a bunch of models and all of them are at best 75% good. At this point I figure I should train it with my own dataset, and so I guess I need to arrange to have this stuff labelled. In my experience stakeholders are usually willing to appoint someone to do it but they want to know how much footage they need to label and whether their team will need special training to do the labelling and after it's all done is this even going to work?

What are some effective / opinionated workflows for this part of the overall process that have worked well for you? What's a labelling tool that non-technical users can use intuitively? How good are tools/services like Mechanical Turk and Ground Truth?

This part of the process costs time and money - stakeholders, particularly managers who are non-technical tend to want an answer beforehand - "If we spend all this time and money labelling footage, how well is this going to work? How much footage do we need to label?". How do you handle these kinds of conversations?

I find this space fairly well-populated with ML tutorials and resources but haven't been able to find content that is focused on this part of the process.
Who is using ATS in production?

When I learned it I wondered why would somebody use it instead of Rust or Idris.
The longer you live the more monthly premiums you pay, so ideally they do want you to live, but they don't want you to use any healthcare services (or use less services) while you live.
You're completely missing the point raised though.

They said there are no real uses of this technology outside of speculation and laundering and your response is that tools for speculation and laundering are useful. That's not really what the argument is here.

The argument is that this technology is being touted as diverse and widely popular when it in fact is not and mostly only used in circular use cases involving itself.
> There is only one group in the entire industry which has an incentive to keep people healthy (insurance) and that is the most hated of the bunch!

A testament that the demand for healthcare services is not only about health results. Albeit there are grave challenges about the way Kaiser or HMO's have supposedly better health results.
I recently went to the store in Austin TX. Like others are saying - the entire PC Hardware / sales department was empty most of the store had empty shelves or shelves that looked very picked over.

The only interesting thing they seemed to have plenty of was UV reactive Sata cables (so wholesome) and Bawls Guarana energy drinks (a favorite past time of mine going to MicroCenter in Cambridge MA).

Sad to say but I think the demise of Fry's is close - but boy was their "western" styled Palo Alto store bizarre and fantastic at the same time.
What is the contract for?
The common open source licenses certainly don't fit with the idea of blacklisting organizations from using them. ICE is probably on the tamer end of governmental organizations using open source too, I'd imagine every intelligence agency and terrorist organization in the world uses some open source code and software.
> This might be a controversial viewpoint, but it's way too cumbersome to pay your taxes in the US currently, and I don't see how anyone but companies like TurboTax benefit from obscuring access to basic tax prep software

That's a pretty widespread view, and the source of this IRS action.
TLDR: OP learned the hard way that a good idea was a feature, not a viable business.
I bought my camera bag from that same Fry's store back in July 2018, and the shelves were full, but it was still a far cry from how I remember it back when it first opened. Very few customers there either. Might have been 10 customers in the store max. Amazing how quickly it went downhill.
Failed entrepreneur, perhaps, but one hell of an entertaining writer and storyteller while throwing in bits of wisdoms. I also came away with one insight at the end. I'm going to sign up for the news letter.
The net result would be that there is less blatant cheating, since that form is quickly found, which seems like a good outcome? Cheating that is only suspected is not at all as bad for the game experience, which is what matters.

"Bikes" whose top speed is 45 km/h are classified as electric mopeds and require traffic insurance and driver's license. They are generally not allowed to use bike lanes. They also require registration plates and turn signalling lights. That makes them much heavier than regular e-bikes.

> I don't know why you are asking for more powerful bikes and then complain about getting less exercise.

Powerful e-bikes are nothing for me, but would be very useful for the rest of the population.
Driving a first-gen Nissan Leaf that we pre-ordered the day we were able. Eight years later, we’ve decided that we’ve purchased our last ICE. By the time the Leaf battery dies enough to be impractical, the ‘05 Scion can be replaced with whatever the new EV hotness (oh, please build the Buzz, VW). By then, I expect range to enough to just have the one EV and that’s it.

But, man, no more stinky, rattling gas-burners, please. I hop in that Scion, it feels primitive. Even our lawn tools are electric. The Honda generator is the only reason to keep a gas can around.

Others have said this, but $40K is a bargain to get this experience. If you include the opportunity cost, my own 4 year start up failure cost me way more than this (even if you don't include lost opportunities it was probably about this sum of money). You still have the database/website that you can continue to run in your spare time and you never know it might even make you a return in future.
It seems like what they're doing is saying "we have a very good idea of what your income is, but fill out this tax form with that info so we can confirm".

That way, it becomes your fault if certain income isn't accounted for.
Well as long as we're taking this route:

NT = nT = nano-tera-(dimensionless) = 10^-9 * 10^9 = 1
IMO this goes to how per-server "communities" were destroyed by the rise of new business models involving follow-on purchases.

Previously (e.g. CS 1.x) you could have a loose federation of privately-run servers, with a certain amount of darwinian-selection for good or bad communities.

However once GameCo starts selling exclusive skins and weapons and XP-boosters and things, they can't allow the possibility of rogue servers just unlocking everything, so everything was brought together under a corporate-hosting-only umbrella. This also destroyed the capacity to leverage volunteer admins, unless the company invested in a mechanism for "you pay we host" servers.
As someone who took up smoking when I was young, stupid, and vulnerable, describing it as a personal decision doesn’t fit my reality. I quit eventually but it took 15 years of stop-start, combined with a constant, desperate sense of guilt and failure.

There are limits to free will. Depressed, anxious, abused and sick people are statistically more likely to make poor life choices. Let’s give them a break.

Agree with what you say though. I live in the uk and it did ease the guilt a little knowing that I was at least paying my way.
I bought a used Volt about the same age and miles for the same price ($10k-$15k). Its starting MSRP was the same as a Model 3 is now. So I have almost all the advantages of an electric car. Model 3s will get there, too, eventually (the fact that used prices are still super high tells you that people love the car... also, they've only had the cheaper trims in large numbers for the last year or so).

Your argument can be applied to any new car. Buying used EVs will be the better deal, just like buying a used ICE is a better deal than a new one. Certainly the case for me. I've spent nothing on maintenance (except tires and wiper blades) and very little on fuel (electricity is equivalent to $1/gallon gasoline).
> I have no idea where you are getting this from.

Experience. I am a farmer.

> if their market price is below a certain price set by the government, the government pays farmers the difference as a subsidy.

Yes. This is insurance. A claim is made if the price fails to meet the insured value. There is also insurance against production output, which covers things like weather events. This is where the vast majority of the subsidy dollars go. Farmers pay 60% of the cost, the government pays 40% of the cost. As such, like I mentioned, for every dollar required in insurance premiums, you pay 60¢, the government pays 40¢.

> I don't know which small farmers you are talking about

The data indicates most farmers have off-farm jobs, myself included. I can certainly talk about my small farm, if you wish. Let's face it, unless you have a large farm, there simply isn't much work to do. You need an off-farm job to remain viable. The customer isn't going to pay you to sit on HN all day long. They will pay enough to justify the time you do spend farming, but the rest of your time is up to you to figure out how to make it pay.

> because in a free market the premiums would be based solely on actuarial data on the frequency of flooding and the expected losses from flooding

It is interesting you mention data, as that is the primary reason why the government operates this insurance system. It gives reason for farmers to report what they are going to produce ahead of time, allowing the government (and private sector) to make informed decisions.

> They are advantaged by being able to lobby to have the subsidies go to crops that they can more easily grow.

I'm not sure what you mean? The subsidies give no preference to what you want to grow. It is simply a matter of you paying 60¢ on every dollar or premium required to insure you. The reason corn producers receive the most subsidies, which is likely what you are thinking of, is simply because corn is the most frequently grown crop – by a large margin. More acres means greater overall risk, and therefore more overall insurance premiums. Which means that the 40¢ on each premium dollar equals a greater amount than a crop with lesser premium demands.

If you want to grow tomatoes, you'll still get 40¢ on every premium dollar you need to spend to enrol in the insurance system. The reason you'll probably choose corn over tomatoes is simply because the market for corn is tremendously larger. It is mostly eaten by animals and cars, which dwarf the number of humans eating tomatoes by orders of magnitude, not to mention much more easily shipped across the entire world. The market for tomatoes is highly localized due to shipping issues (before reaching the processor) and a fairly tough sell in comparison due to the much smaller market.

> Nuclear power is, but the environmental movement is actively blocking re-investment, and we're so far behind that it would take decades to jump-start the industry.

That isn't true. With desire and enough money, we could be churning out small modular reactors (SMRs) by the thousands. ThorCon, Nuscale, Terrapower and many others have designs.

In fact, that's my recommendation for the conservatives/populists. Take climate change away as an issue by promoting the only workable plan - a massive shift to nuclear power generation along with "renewables".

Even if global warming isn't an emergency, clean air is a good thing, and so is cheap, plentiful power.

I tried to play "Sea of Thieves" and gave up entirely after about an hour. They have a feature where the majority can vote to send someone to the brig, where you can't do anything, except apparently drown if your teammates sink the ship. Then you get to come back to life, in the brig still. I never even got a chance to play the game, so there was no reason to vote me out other than just to troll. And this happened repeatedly with every crew I was matched up with.

There may be valid cases for these "vote to kick" features, but they do get blatantly abused as well. I don't think they're a good replacement for more intelligent matchmaking.
60% on a per-frame basis might be enough if all you need to do is identify the condition "two supervisors are not on the floor" for at least 20 minutes.

As in, if you compute your per-frame score and compare it over bigger chunks of time, is it sufficiently different when 2 are on the floor and 2 are not?
I haven't been to Fry's in a while, but every time I went I always wondered how the hell they managed to stay in business. My random observations over the years of dealing with Fry's:

- Almost all the floor people are paid in part on commission. Even the cashiers salary is in some part commission based. Like, how can a cashier have any control over what somebody purchases in order to maximize their commission?

- Their Point of Sale software seemed to be the most antiquated homebrew garbage on earth. The thing would print out a mile long receipt, even in their cafe. Like, to order coffee the cashier had to do a bunch of steps in on the terminal just to complete the transaction--super bizarre. I'm pretty sure some owners nephew "who knows computers" must have programmed that thing way back in the day and the owners never bothered to modernize.

- The stores always seemed depressing, even ten years ago. Shelves were always dirty with crap strewn about. The isles always had some shelves that were empty with no inventory, or the majority of the inventory out of stock.

- Years ago my monitor crapped out on me and I had an extended warranty. The cheap fuckers didn't replace it but actually wanted to spend several weeks somehow repairing it. I still have pictures on my phone of the absolute mountain of paperwork they gave me for this processes. It was completely insane.

- All the people working there never seemed happy. Several times I overheard employees yelling at each other in neighboring isles. I always got the feeling store management was running the place like a pressure cooker--"gotta sell XYZ of whatever or you are fired" where "XYZ" was some product nobody on earth wanted.

In short, Fry's always had a weird vibe to me. I'm surprised they managed to make it this far.
Some more context; she didn't ask for 15 different opinions, she lived in the country side and her nearest hospital used relay doctors. So, it was more a case of being sent home and told to return if it didn't get any better, and when she did return, her previous doctor was long gone and had been replaced. All the next doctor had was whatever the previous doctor left them to work with in her charts. I'm not a doctor, so I don't know how much that would be in a case of a piercing headache.
Don't forget "Mostly harmless."
You might be tired of it, but what it underscores is that Google has developed a reputation for creating experiments and killing them off when they no longer serves Google's purpose. It reminds Google's users that they're not customers, but proverbial farm animals whose attention is being auctioned off to advertisers.

I get why they need to kill off products. I took a few minutes to look through https://killedbygoogle.com/ and there are a lot of fleeting, gimmicky things on that list that should have never been released in the first place.

Google has an image problem with this. By releasing all these unfocused products into the wild, they've signaled that they will create unfocused products and kill off the ones that aren't hugely successful.

Now when they launch a new idea, people are no longer excited, but legitimately suspicious. When Google launched Allo and Duo at the same time (while Hangouts still existed), it sent a clear message that they really didn't care about product management and continuity or communicating to their users. They would rather be the ADD company that built 3 competing things and measure usage than to nurture and improve already successful products.

People don't like having the rug pulled out from under them and the repetition of this trope will continue to echo so long as it resonates with readers. Even if it's FUD, this is a big problem for Google.

I don't think Chrome OS will be on this list anytime soon, but if something shinier comes around, can you honestly tell me Google won't drop Chrome OS for the shinier thing?

Well, they're comprised of that, and, y'know, children being murdered in mass.
Yes but the IR locked onto a higher temperature source, not cooler. My understanding is that a shadow would be cooler.

Other remaining factors include that:

- Primary radars on both fighters in the initial pass were being jammed

- Passive radars on the Nimitz were what directed the planes to this spot initially

- It was approximately 9:30-10 PST, so any shadow from <40k feet would be coming from restricted airspace

- Multiple visual contacts from multiple angles, including from slightly below/ to the side

This one is pretty difficult to explain in conventional terms, unless you think it's all a hoax. Pretty fascinating stuff, huh?

I was borderline. Higher bp increases your risk of stroke. I figured the headaches were a warning.. I could be wrong about that though.. I take a very low dose ace inhibitor and it works great. Doc said it wasn't a permanent thing necessarily.. I could probably go off of it if I was more consistent with the DASH diet and exercise more and drop 15-20 pounds.

Keto diet supposedly helps drop the bp too but diets are really hard to maintain and stick with.
Great writeup. Very honest.

His problem is that this product neither increases the revenue of the practice nor does it reduce(or remove) any existing cost. Without that it's a cost center without clear benefits.

> It had been a bit of a working assumption of mine over the past few weeks that if you could improve the health of the patients then, you know, the doctors or the hospitals or whatever would pay for that.

No. Or at least you better show clear benefits becuase EVERY medical product makes claims that they improve patient health or patient outcomes.

What he needs to do is figure if there is some costs that are currently incurred by hospitals and practices that could be reduced or removed by using his product. If he can do that, he'll get sales (and in fact, there is a lot of money in 'population health' and related fields). Otherwise, he's got nothing.
Yes, already read it! I like Three Body Problem better, but Blindsight is excellent.
I used the one in Cincinnati and Chicago quite a bit. Cables and other items I'll still get off eBay or Newegg unless I need them that weekend and am willing to pay the retail upmarks, but for a lot of higher end products, the prices are not too far off from online retail stores (I stopped shopping at Amazon in 2016 so I can't compare to that one; just eBay and Newegg mostly).

There are a lot of products on their site that are "in-store only" which is a good model .. if you happen to live near one. I'll even pay an extra $30~$40 for something high end like a monitor since if something is wrong with it, I can just return it to the store and not have to worry about packaging it and shipping it back.

One of Liu's most interesting ideas regarding aliens observing us was in Ball Lightning, written before Three Body Problem.

In Ball Lightning, humans are doing experiments with quantum phenomena. They're doing it deep underground in the most isolated environment on the planet. Yet for some unknown reason the wave function keeps collapsing even though there are no observers present.

That's when they realize, there are observers present, just not human. Alien intelligence is spying on their experiment. But shortly after they realize this, the quantum experiments begin functioning as expected, no wave function collapse. The alien observers realize they've exposed themselves, and stop spying on the quantum experiments.

That was pretty mind-blowing, especially after learning about the Sophons in Three Body, which were clearly the alien observers in Ball Lightning.

> ...called the ICE contract a betrayal of open source’s commitment to “inverting power structures and creating access and opportunities for everyone.”

Hmm, interesting. I always saw open-source from a freedom and power angle. I have a program, I should be able to edit it. I never saw it in a social justice angle of "inverting power structures". It may well be the case that having Linux be GPL helps Amazon more than me and entrenches power structures and I'd still not be upset because it does help me.

I've replaced the battery twice, last time in september 2019, and this last time it costed me 60 EUR, and the battery life is much better than the original one.

I might want to replace the battery again in the next 3-4 years if I still have this laptop, and you might be right in that this might not be possible, but at least today it is.
