The term has a long history - as the Wikipedia page [0] points out, "knowledge base" was used to distinguish systems that could actively reason about data using rules (and a rules-engine to run them) -- e.g. expert systems -- from databases, where the data just sits there. However, these days, it's used differently:

From the Wikipedia page[0]:

Knowledge management products adopted the term "knowledge-base" to describe their repositories but the meaning had a subtle difference. In the case of previous knowledge-based systems the knowledge was primarily for the use of an automated system, to reason about and draw conclusions about the world. With knowledge management products the knowledge was primarily meant for humans, for example to serve as a repository of manuals, procedures, policies, best practices, reusable designs and code, etc. Of course in both cases the distinctions between the uses and kinds of systems were ill defined. As the technology scaled up it was rare to find a system that could really be cleanly classified as knowledge-based in the sense of an expert system that performed automated reasoning and knowledge-based in the sense of knowledge management that provided knowledge in the form of documents and media that could be leveraged by humans

You probably caught him at a bad time. He's also argued that third parties are the only way forward in America (which I think is not true). At this point, his Common Sense podcast is somewhat repetitive of his previous stuff, but he's trying to say new things each time, which is tough.

His Hardcore History stuff, on the other hand, is mind-blowingly awesome!!! And not repetitive.
Many others agree that they aren't left leaning. Who is correct?

And telling us to just Google it is a ridiculous non answer. Don't waste our time.
When I worked at a very large bricks/ecommerce retailer, the FTC had their eye on us for decades, so we had very complex pricing rules to make sure that we established "regular price" for a certain number of days before an item could be put on sale, and could only stay on sale for a certain percentage of on-sale days, then once "marked down" or "clearance" could never have the price raised again.

I'm guessing the FTC will have their eye on Amazon pricing soon.
In the 1990s, I was thinking of this for legged locomotion over rough terrain, fast turns, and such. The idea was to use a mediocre but fast physical simulation to answer "what-if" questions, allowing planning of moves about two or three steps ahead in the real world, or at least a realistic simulator. Then use a learning model to learn corrections for differences between the mediocre simulator and the "real world", or good simulator. The system would start out somewhat klutzy and get better. Eventually, perhaps to the parkour level.

Once you have a model, you can invert it to make a controller, as the post above points out. For classical linear models, this can be done analytically. For non-linear models, you can use the model to train a controller, running the model with random inputs to generate a training set.

(I spent several years working on the simulator problem, shipped a simulation product ("Falling Bodies", the first ragdoll simulator that didn't suck)[1] and eventually sold the technology to a physics engine startup and went on to other things. Even today, as Sony and Boston Dynamics have demonstrated at great time and expense, there's no market for legged robots yet.)

I tend to think one way. To help me understand the "other way," I try to understand their belief system before I try to understand their arguments. Let me try to use two examples, one from each side. Don't worry about why some people believe in welfare before you try to understand their beliefs in "justice." Don't try to understand gun rights before understanding "liberty."
You got me curious, so I looked... page 1082 and 1083 of the Sears catalog, from 1912 https://archive.org/details/catalogno12400sear shows that a standard hammer was $0.66, and a hand saw was around $1.50 (there are several models from $1.05 to $1.95). So $0.66 (from 1912) is $15.82 in 2016, and $1.95 is $35.96.

"Basically I skip breakfast, eat a light lunch around 1, and a large protein/veg heavy dinner."

Apparently you are my dietary twin. I came to this exact formula accidentally, though, as a result of calorie counting. I skipped breakfast because I could do that most easily. Then I decided lunch would be really light because that gave me the leeway to have a more satisfying dinner and feel completely full once a day. And I didn't want to take the risk of having a light dinner, being hungry, and being unable to get to sleep.

I ended up with the mix of protein- and vegetable-heavy dinner because I started reading the nutrition labels of absolutely everything. Then without seeking out a particular type of food, I tried to remember which foods seemed like a good combination of filling and low calorie. And protein and vegetables is what it ended up being.

Overall it has worked great. The types and amounts of food I eat feel normal now, and I feel good, and my ability to control my weight has surpassed all expectations.
>Simpson says Amazon is breaking Section 5 (a) of the FTC Act that prohibits "unfair or deceptive acts or practices."

>“It’s strategy called ‘Price-anchoring.’ It’s pretty common across the board. Now as far as it being against the law or breaking any rules or regulations, it could be considered false and deceptive marketing under the FTC Section 5,” Kelly adds.

Many States call this practice out specifically as an unfair trade practice in their laws as well.

Let me introduce you to the story of hurricane Sandy. Verizon doesn't want to rebuild its union encumbered wireline network so they wanted to switch people over to local wireless.

That was a weird concept for me to learn as well. When your surgeon is in-network, you kind of expect the anesthesiologist to also be in-network. But surprise! $3500 for anesthesia.

My heart was broken when I was shown that RT supported Bernie. You can find out what Russian Active Measures are pushing by what RT is pushing.

RT can be independent, but you have to know when they're pushing something, and when they're not. I don't have enough time for that.
I think this practice mostly falls under state-level regulations. The government of California in particular seems to have gone after a slew of major retailers (including Amazon) for similar practices. Thus making your username doubly appropriate, I guess. It's hard to follow the outcomes in the hits I'm seeing, though.

Actually, negative wages are allowed by the government.

But the main confusion is between work and job. Works is anyone performing a task. A job is someone paying you for that, and in the strict sense, someone hiring you to do it on a contract.
If Esperanto ever became the dominant international language people would start making blockbuster movies in it, kids would start learning it, and younger people in smaller countries would use it more than their native tongue.

Then it would start to displace a few native languages until it became some community's native language.

After that it would start to fragment and evolve and lose all the simplicity that comes from it being an artificial language.
It's not safe to assume the arm that has the watch will be available to operate gun.

People practice one handed reloads and failure drills.

Even in competition you are regularly required to alternate no strong hand only and weak hand only so it isn't possible to put the watch on the right hand. Proper technique also has you anchoring the unused arm.
Why do you say that? Esperanto has actually been relatively successful in Asia (as the article details). Yes, its grammar and lexicon are unrelated to any east Asian languages, but it is nonetheless easy to learn, to the point that it is sometimes used pedagogically as a "first European language" in Chinese universities.
Conservatives can be looking to hurt Amazon and Amazon can be hurting consumers at the same time. I don't see how you can argue that lieing to consumers is not hurting them

In my opinion, being a person who tries very, very hard to read both sides of everything to form my own intellectual model (it's a bug, not a feature), NO. One does not exist. YET.

Editorial independence in the current US environment is simply not possible using traditional models. Disruption has been taking place, but it's not all constructive. Bezos buying the Washington Post was one marker, and Thiel helping destroy garbage Gawker is at the other end of the spectrum. Hanging in the balance are tens of millions of people trying to find the truth.

Honestly, the only website I can mention in confidence is Medium, and it still suffers from signal-to-noise ratio and present models of information / emotion distribution.

This can be changed, but it will take somebody planting a flag so far out on the scale of TRUTH like Hunter S. Thompson railing against Richard Nixon and in spite of his own significant issues. The dialogue has changed, the methods have changed, and they have surpassed our adaptation capability timing in my opinion.

There is an opportunity for Journalists and Writers in the United States to re-ignite the fire that the First Amendment was designed to protect. It's the natural order of things, we're witnessing evolution, and also participating in it. I have hope that one day a team can come together to build on what ProPublica and The Intercept aimed to achieve, but do it in a fashion like Kurt Cobain when Nirvana's songs and messages suddenly turned people's attention from junk-food-Hair-Metal toward something worth giving thought.

I'm optimistic.

Sounds like a possible factor. Inflation-adjusted median household income in 1900 was around $12k. Now it's around $55k.
I have a top-end Roomba 980 like the GP is referring to. They don't use random exploration. When you start a cleaning cycle, it begins working in a back and forth cleaning pattern of parallel lines. When it runs out of room to perform the back and forth lines, it moves to a place where there's a "hole" in its map. That may just be a corner behind a chair, or it could be a doorway to a different room. It basically repeats this process until it has filled in all the holes and built a full map of the room, level, or whatever area you're letting it vacuum.

The algorithm definitely isn't perfect. It might clean half of the room where it starts, then wander around and clean most of the house before making its way back to finish that room. Still it seems to work well overall. What really fascinates me is how the algorithm and SLAM mapping gives it very familiar behavioral patterns. For example when it's coming back into a room that it's already visited, it might drive just inside the room, pause, "look" side to side (panning the camera to find landmarks it recognizes), then continue on.
I regret writing "not newsworthy" now. Although the point I made still stands: this is nothing new.
In the sense that it is way easier for native speakers of Europeans to learn than for native speakers of languages such as Asian languages I don't think it actually succeeds in the goal of decolonizing, if you will, the lingua franca.
Individual, or group plan?
Sort of. There are some rules. Note that this varies by state as well, federal law is probably nonexistent.

An old state law which for all I know was repealed ages ago or whatever was that an item couldn't be marked as on sale for half the year or more. You couldn't say it was 40% off for 300 days out of 365, that sort of thing. The easy workaround was to make it 40% off for three months, then have it on no sale at all but mark the sale price as the original price for the next three months, and switch back and forth whenever you want. So long as the item wasn't always marked "on sale" you were fine.

I don't think the US has ever had real evidence based tests like that, except in major class action suit which have largely ceased to exist thanks to mandatory arbitration clauses.

Two days to schedule with a GP? That's insane... In Australia (with our universal healthcare) it's pretty much always same-day for a GP... X-rays and blood tests are generally same day and free, I've even had an MRI scheduled for next-day (just a knee thing, not an emergency) and again no out of pocket cost.
It's really cool to see the people behind websites that I use post on HN!

there is no 'party of the people' in the US. or if there is, their political clout is at best described as 'trivial to nonexistent'.
Nobody can guarantee their software is secure (secure software doesn't exist), but the cash value of a sandbox escape/jailbreak of iOS on the black market (or probably even through Apple's bug bounty) far exceeds the value that would be generated from some adware or cryptolocker scam all but guarantees that you won't see any widespread malware.

I got this when it first came out, I was kind of doing it in a "gut feeling" kind of way, but this made me think of it more as a discipline, and solidified the idea of micro improvements and let me drop the idea of trying to get it exactly right the first time.
"trusted seller"? What does that mean? What makes Amazon a "trusted seller", and why should we expect them to be different than any other seller?
Poor analogy on my part I guess I wanted to use an example so simple it would be clear that seeing the result wasn't my goal knowing how to get to the result was what I wanted to know. Telling me the answer to a problem isn't helping me teaching me is helping me. The "give a man a fish he eats for a day but teach a man to fish he eats for life" philosophy.

You don't need Elligator to make DH-EKE work - you can do it with old-fashioned DH. The property you need is roughly that D(E(g^a, pw), guess) has the same distribution regardless of whether pw == guess. If the group is Z_p and g generates the whole group, then E could be a pseudorandom permutation of [1,p-1].

The problem with ECDH here is that group elements aren't just numbers.

As a Romance language, Sabir cannot be a Frankic language, since the Franks were a Germanic tribe speaking a Germanic language.

The wikipedia article notes that by the time of Sabir, "Frank" had turned into a generic term for western Europeans, which makes the term make more sense -- to the Byzantines, Italians and Spaniards were "Franks". Left unexplained is why the Byzantines would refer to Sabir with a phrase in Latin, a language they didn't speak.
Back at an old startup when I had a lot of data from clothing retail websites, including historical prices and sale status, I ran some queries out of curiosity to look for this.

I'm pretty cynical but I was still shocked at the number of results. This seems to be a completely normal practice. Price and being on "SALE" seemed to be optimized or A/B tested almost separately. And the "regular price" field on sale items was garbage data that correlated with nothing.
What's the difference between this and opentracing? AFAIK opentracing is built by the people who created Dapper at Google, and the project also has a set of standards for HTTP transport.

log2(10^16) = 53 bits of entropy or 300 years if your attacker can do a million guesses per second (the link says 1000 keys per second, but that's on the CPU).

I've become more and more disillusioned by Amazon over the years. Prices are now almost never the best; I only buy from them when I need something quickly (and can't get it locally). NewEgg (nearly) always has better tech prices. Walmart often has better prices on everyday items and I can have it immediately. I just bought a pair of tweezers at my local grocery store for two bucks that was $6 on Amazon for the same make/model; sure, it's a terrible item to sell online because it's tiny and cheap and shipping it with prime shipping probably costs as much as the item itself, but I thought they'd solved that problem with "add on" items.

I mean, Amazon is still a very good customer experience, but when I'm buying something big I always comparison shop now. As recently as a couple years ago, I would just buy it. No thought to whether it might be cheaper elsewhere. The convenience of Prime, plus the reasonable confidence that the price would be competitive with everybody else, was enough to where I didn't bother comparison shopping.

Obviously, Amazon isn't hurting. But, I can't help but think that having more of their longtime customers starting to comparison shop is a bad thing.
Off-topic, but that's a truly terrible bike. I know a few people who've gotten it or similar GMC's as "the first result on Amazon for road bike" and they've all had problems with chains breaking or very poor fit of components.

All current Roomba models [1] have wifi and app support. The app requires an account because it's the type where even when you're at home on the same network as the Roomba, the app doesn't actually talk directly to the Roomba, but goes out through iRobot's servers. Not sure about other models, but on the 980 that I have, the app is necessary to use the full functionality.

> That's not a valid comparison.

> simple viruses

Read these words again. Regardless of whether there were tons of viruses on MacOS back in 1997, there's no way it's valid to hold up your thumb, squint, and say the current situation is better or worse. The malware on MacOS 8 was almost exclusively viruses made by hobbyists which self-propagated through channels that no longer exist. There were no command and control servers, strong encryption, muti-stage deployments over the web, etc. Modern malware is organized crime that relies primarily on people scamming other people, and requires a ton of back-end infrastructure and support.

In other words, it's harder and success depends on a whole different set of factors.

The person I was replying to was basically asserting that Apple fixed the virus problem that existed before OSX, and as a result malware cartels in 2017 aren't able to attack OSX. Would you believe it if they were saying polio vaccination campaigns in the 50's put a dent in drive-by shootings in the 90's?
The FBI certainly would be interested!

Interesting. I also find myself picking up tech from NewEgg more often than Amazon. And I recently ordered most of the supplies for a cocktail party I was having at Walmart and Bed Bad and Beyond.

Amazon prices might beat local retail, but they are only sometimes competitive with other (often more specizlized) online retailers at this point.

Also, at least for me, shipping New Egg, Walmart and BBAB was faster than Amazon. I don't have Prime however.
> Moreover, the real world is (for practical purposes) continuous. The robot would have the option of engaging one of it's motor for one millisecond, or two milliseconds, or three milliseconds, etc.

Are there not similar techniques to search trees that are used here? Obviously you wouldn't enumerate all options but you'd think you could guess at some practical ones then guess options between the most promising. Either way, it just feels "imagination" is making it sound like an entirely new approach when heuristically pruned search trees could be described in the same way to me.
One of the remarkable things about English is how little it varies from country to country, especially in written form. There is much more variation in how French, Spanish, and Portuguese are spoken and written in different countries.
Over and over again I've realized just before or after buying an item from Amazon that I paid way too much. I have finally broken the ingrained habit of leaping before looking. That can't be good for Amazon if too many people do that.

On another note, I am beyond tired of the craptacular deals that are >80% fly-by-night products with astroturf reviews. The gold box deals used to be a favorite bookmarked stop.
