Yeah, I've personally run into that myself. It's not that the listings are being renamed, it's typically that the seller is listing their product as a "variation" of the other product has has good reviews.

What you're describing is another kind of abuse called Listing Abuse, specifically Variation Abuse. If you encounter Listing Abuse, use the link on the page "Report Incorrect Product Information" [1] and say that the product is experiencing Listing/Variation Abuse, and give a couple examples of reviews that are clearly for unrelated products. It will be investigated, taken down/unlinked from those reviews, and the seller will be punished as appropriate.

("Variations" are products that have different SKUs but are all linked together and share reviews, such as the same product that comes in different colors or patterns or sizes. For example, the Speedo Swim Cap has 20+ color and pattern variations: https://www.amazon.com/Speedo-Silicone-Solid-Swim-Black/dp/B... . Each is actually a distinct product SKU, but since they're all functionally the same, just with different colors or patterns, they have one page and share reviews.)

The fundamental problem that makes Listing Abuse hard to stop is that, if you allow people to sell on your store, that means you allow them to enter their own product information -- which you don't have any way to verify. There's no World Authority for Product Information that you can check against. And not all sellers use Fulfillment-by-Amazon where Amazon holds the inventory; plenty of sellers ship the product themselves, meaning that Amazon never has an opportunity to see or inspect the product. Even if Amazon had a policy requiring new sellers to ship a product to Amazon to inspect, that wouldn't stop malicious sellers from shipping something different to customers.

Sellers have a lot of power to describe the products they're selling that they legitimately need. Unfortunately this means they have the power to list their products as variations of other highly-rated products to falsely make them look like they have a lot of good reviews. This is another one of those problems that is difficult to solve, because you need to give sellers access to describe their products to support legitimate usage patterns, like adding a new variation. (Like Speedo deciding to offer yet another color or pattern beyond their existing 20+).

All that being said, I agree that this should really be one of the easier types of fraud to stop, and don't understand why it's taking so long for the company to shut it down effectively. I think they need to build some machine learning systems that compares product information to review content when new variations are created, to flag likely variation abuse for human review. I also don't understand why variations are not required to all be shown on a single page (which would stop the abuse); there are probably legitimate use-cases that require it.

> A collector could just bid on bulk cards, but how would they know it's not picked clean of the good ones?

Lots of trust. A good collector will glance through it and determine if it's something they want to take on. Those bulk sets are usually sold cheap enough that it's worth the risk.

I've sold a few sets and made clear each time that I'd an eBay seller and glanced through them but didn't have time to really dig in.

If you're just blinding buying lots online though you're gonna get screwed.

Wait until people accidentally an ML model?
This seems really cool, but I don't get why they would pour work into this while simultaneously building a C++ front-end for PyTorch[1]. Per the blog post, both frameworks have the goal of empowering ML researchers to iterate on ML models in such a way that it becomes easier to reason about performance than it would be talking to a bunch of dynamically linked object files behind an interpreter.

Facebook is a huge company with lots of money, but production-ready ML frameworks are a HUGE undertaking. I don't get how tech companies can be simultaneously recruiting and doing interviews year-round, paying huge salaries and then putting them under a layer of management that thinks two different C++ ML frameworks with the same goals is a good idea.

Facebook's work on Tensor Comprehensions, Halide (not originally FB but they have contributed heavily), Glow, and PyTorch all contributed to the ML space by offering alternatives (with innovative UX/technical differences) to the Tensorflow ecosystem. Not all of these contributions had novelty, but I respect FB's choice to work on something for the sole purpose of not having it's direction beholden to the whims of Alphabet (see: Swift for Tensorflow).

I just don't see what this adds which FB isn't already working on within a different project. What am I missing?

I'm tech savvy, raised my kids internet liberal, gave them lots of freedom and educated them so they could protect themselves without adult supervision. Training to cope with unexpected situations is far more important than withholding them from exposure because you won't be there when it eventually does happen.

With all their experience and knowledge, they are now warning me: "Dad, facebook/instagram has become a toxic cesspool that isn't fun anymore and should be avoided at all cost!!"

"Most" is an exaggeration. But many? Yes. In a survey of scientists from 16 countries (http://spectrum.ieee.org/at-work/tech-careers/the-global-bra... ), the US is the top destination from 13 of the 15 others and the #2 choice from the other two. If you are a Canadian scientist, there is a 16% chance (https://www.reddit.com/r/dataisbeautiful/comments/37lgxg/the... ) that you will move to the US. That's not "16% of all Canadian scientists that move out of the country move to the US". Let me repeat: *16% of all Canadian scientists move to the US.* They're also likely to be among the top Canadian scientists, too.

By comparison, 5% of all American scientists move to another country, of which 32% go to Canada, so about 1.6-1.7% total. Since the US has nine times more people, that means that in absolute numbers the 1.7% of American scientists is about equal to the 16% of Canadian scientists, but there is no reason to think that the 1.7% makes up the top tier of American scientists; why would the best move north of the border? In other words, the US is receiving the best of Canadian scientists in exchange for an equal number of its non-best.
People were flipping cotton candy grapes. It's insane.
I turned down a contracting opportunity that would have been exceedingly lucrative for me because the contractor wanted me to take liberties with what I've done all in the name of greasing RFP's for government procurement.

Was initially stoked and honored to be considered, but the longer I thought about it, the more uncomfortable and heavy the thought of how it all worked started to sour me to the entire idea.

Never realized how pervasive the whole practice was til then. Thought it was a rumor or story... Turns out...
The biggest changes I've seen is that whenever I meet something new that I'm not familiar with, I learn way faster in the tranquility of my home than in the office.

That means I get productive more quickly and thus more productive. In the last year I was able to pick up a lot of technologies that I've been putting off for years because I couldn't find quiet time to sit down and bang my head against the documentation.

You're asking a lot of immature, status-obsessed humans to go out of their way to accommodate someone. They might not even be "friends" yet, just social groups that one might like to be a part of. How are you meant to make friends if you can't participate in popular bonding exercises in the first place? WhatsApp groups are social venues in their own right.
You raise some valid concerns, but this cooling paint has far more chances of being applied in reality than any of the "breakthroughs" you are alluding to.

There are really no disadvantages of using this as a white paint.

Barium sulfate is abundant and the cost of a paint based on this pigment should be very similar to the cost of the current titanium white based paints, once the pigment is produced at industrial scale using the process developed by this team.

There are no environmental concerns, because barium sulfate is as inert as titanium dioxide. Actually there are various living beings which use barium sulfate as a bio-mineral, instead of the more frequently used calcium salts, like in our bones.

So both in cost and environmental properties and also in maintenance properties the proposed white paint should match the currently used titanium white paints, with the difference that it can ensure that any painted surface exposed to solar light is cooled instead of being heated.

Only this will certainly not be enough to save the world, but it will certainly be a useful product.

For me the answer is because that’s not the kind of place I want to live so it’s not the kind of place I want to build. We don’t really have a shortage of conventional suburban housing. We have a critical shortage of walkable urban housing, the so-called “missing middle” which is denser than conventional suburbia but still single family.

A great example of that is the older parts of San Francisco, where I lived for years. There are lots of old Victorian homes that are comfortable single family residences with nice back yards, but at about twice the density of typical suburbia because they don’t have side yards (aka they are townhomes). Mixed in there are lots of 2-3 story buildings with shops and offices on the ground floor and apartments above.

That was a wonderful place to live! So wonderful, and also so scarce, that every place like that around the country is skyrocketing in price over the last 10-20 years.

What I would love to do is build a new town of middle density, “European style,” if you will. But that is so scarce because it’s illegal to build in the vast majority of US land area.

Hence, to do it, you need to be building somewhere outside the jurisdiction of cities and counties with conventional zoning, which really limits your options.

And finally, 200 homes isn’t enough to form the critical mass of a European small city. You probably need more like 10k homes (for a population around 25k) for it to work.

The social norm these days is really different. It's not about your friends suddenly starting a new, exclusive behavior; its about a slow migration of the people in your social world to a tech platform you don't have access to. And kids do get left out because of this--not for nefarious reasons, but because they're just not going to be in the loop for a significant part of the social interactions that are taking place.
I'm not really in the industry. But I know that high-voltage MOSFETs / IGBTs need substantial amounts of current to turn on / off adequately. Under typical use, there's a dedicated chip called a "Gate Driver" that provides that current, between a microcontroller and the IGBT.

Its not that the IGBT / MOSFETs are built on these microcontrollers. Its that the Gate-Driver can be integrated into a microcontroller (simplifying the circuit design and reducing the number of parts you need to buy).

Under normal circumstances, a microcontroller can probably source/sink 1mA (too little to adequately turn on an IGBT). You amplify the 1mA with a gate-driver chip into 100mA, and then the amplified 100mA is used to turn on/off the IGBT.

By integrating a gate-driver into the microcontroller, you save a part.
To describe a microcosm of this line of thinking, let’s take Pokémon cards. Packs containing a (foil/holo) card weigh more. A sealed box of packs is theoretically a gold mine. But how do you establish that the presealed box wasn’t raided and resealed? A whole system of trusty discoverers and buyers play hand in hand.

Individual packs will always be looked at with doubt, since they’ve probably been weighed and sorted.

> Amazon cares substantially about stopping these things.

And yet Amazon doesn't even let their customers choose the correct reason for returns when they receive counterfeit items. Instead of being able to choose "This item is a counterfeit" or "I believe this item is a counterfeit", the customer must choose between reasons for their return that aren't entirely accurate, like "Inaccurate website description" or "Item defective or doesn't work".

You'd think that a company that claims it is throwing vast amounts of resources at stopping counterfeiting on their platform would at least try to collect data on the counterfeits their customers receive.

If you want something that has the same basic usability, ie plugs directly into USB and is really easy to use with computer audio, buy the Apogee Mic Plus.

I recently experimented with pretty much everything in this category and was very happy with this model, bought a dozen of them for use in a virtual conference series, where I wanted something I could send to non-technical people who'd never be able to navigate a pro audio interface. I've been very happy with it so far.
> This bubble is going to pop with a devaluation of the dollar or a devaluation of everything else.

I'm not sure where you get the idea that the dollar is suddenly going to lose a ton of value. People have been calling for this since the beginning of time, just like the people who keep trying to short the S&P 500. It's not gonna happen, certainly not any time soon.

You are also qualifying "Young" "children". Doesn't the definition of children mean young human, so what are you communicating here?

in the real world, we have this thing where a teacher can upload an education video using two clicks of an iPhone and as you said, this uncorks pandora's box of goodies for kids.

It seems odd to me that the same thing we regard as inherently harmful to children is simultaneously regarded as a necessary human right for adults.

It also has little if any basis in the legislative rationale of original antitrust legislation in the US.
