The real problem with economics (as perceived by somebody that first studied applied mathematics, and then macroeconomics, and then went into management) is that it styles itself an annex of mathematics, but lacks the invariants necessary to construct the deep symmetries typical of physics or other hard sciences. We literally have nothing to work with other than those superficial relationships econometricians can measure and somehow boost into statistical significance.
I glanced at the lecture notes and this looks much different (imo better) than your usual stats course. I didn't even see any mention of the usual hypothesis/significance testing mumbojumbo that has been causing all the trouble. They say:

"It is a course intended for those that value the role of Bayesian inference and machine learning on [sic] their research."
I had trouble reading the whole article on mobile; screen-eating ads and forced scrolling to the bottom.

But what I read just reads like a lengthy ad.

Also, "only"? I know it's HuffPo, but come on. How about electronics? Where am I going to find a few 74-series logic chips in person? How about materials like PTFE? None of my local plastics stores carry it.

Sorry, am I sounding like an ass? I feel like that was sort of an ass-y thing to write. But these 'submarine' pieces really bug me.

Yes. I recently bought frames from Zenni and paid $30 total, including an upcharge for an oleophobic AR coating (something I have not seen available offline).

These were 1.50 index cr-39 which is fine for my light prescription. But higher index lenses are only a few dollars more.
The Story of the Gömböc (2009)
I don't know about the latest research but I suppose a few people can be intolerant to chlorine at a much lower dose than most people. It happens with pretty much every substance, natural or man made.

As for your example, are you sure it is due to chlorine? From you description, there are simply too many variables. Sure, he stopped using chlorinated water, in fact, he changed water completely. He also moved. It means it can be caused by the mineral composition of water, plumbing, air quality, volatile organic compounds, etc... And all that is excluding psychological causes.

Anyways, I won't criticize your friend, he obviously made the right decision because he feels better, no matter the underlying cause. The problem is that to extrapolate to other people, we need more than anecdotal evidence.

This wide choice is actually putting Linux at disadvantage: instead of consolidating efforts to create one decent desktop environment we have half a dozen of half-assed ones.

During WW2, the Captain of U-boat 156 sunk a passenger liner. He then immediately set about rescuing survivors, and began broadcasting his position and the humanitarian nature of his mission on all available channels. An American B-24 in the area began to attack, despite the Captain's pleas they were killing their own men and the U-boat was trying to save lives. Afterward, U-boats were explicitly ordered to never render humanitarian aid under any circumstances (the Laconia order). The B-24 pilots were given medals for bravery.

In 1757, the British admiral John Byng was executed for failing to sail his ships into a storm. The enemy was besieging a fort, and although Byng engage the enemy fleet he didn't pursue and annihilate them - heedless of the danger - and thereby the relief troops were unable to reach the fort before it fell. This was considered a capital offensive despite being sound strategy (the loss of the fort was bad, the loss of Byng's fleet would've been crippling) - making the right call got a man shot by firing squad.

These two incidents are always in my head when people discuss morality or honor or any such topics. The truth is "moral" for most people means nothing so much as "Did a thing I like" and immoral means "Did a thing I didn't like". That B-24 crew attacks the enemy, which is good and therefore moral - that it was a supremely cowardly and bloodthirsty thing is irrelevant.

It's just how people are, I suppose. Well, most people. Some are genuinely good eggs, and those are the ones to befriend.

You won't anymore. Predicting a particular narritive is akin to decide what will happen. The more you force the future, the more the future tries to become the past. If the future is the past, then there is no progress made. No progress made, and you have a loop.

Trivex is great and 1.60 is a close second in trade-off between optical quality, thinness and impact resistance. For lenses stronger than -5 diopters, a smaller frame eye width (< 45mm) will minimize lens edge thickness, http://www.youngeroptics.com/pdf/trilogy/Trilogy_Monograph.p...

Rkt is functionally different enough from Docker to be called a different tech, and Kubernetes is, like, a totally different category. Are you also calling bicycles, cars and motorbikes the same technology, because they all use the technology called "wheel" somewhere?
The deepfakes subreddit is remarkable - people without any prior background in machine learning or programming are asking tons of questions and learning all about deep learning.

Yes, I bought a pair of prescription sunglasses glasses and a pair of regular prescription from Zenni for less than $100 total.
I’m an applied mathematician turned macroeconomist: what you accuse in your first two paragraphs is true, but it is not for want of trying. We just lack the invariants and symmetries that physicists luxuriate in. We literally have nothing more to work with than what statistics can measure, typically as ambiguous time-series with dozens of aggregate variables subject to wide observation errors and biases. It’s pretty awkward, and we’re very much aware of it.
"The big story of 2017 in the US was the beginning of the end of white male dominance."

"[Trump] is the epitome of white male dominance. An unapologetic (actually braggart) groper in chief. I think it took something as horrible as the election of such an awful human being to shock the US into deciding that we could not allow this behavior any more. Courageous women such as Susan Fowler, Ellen Pao, and many others came forward and talked publicly about their struggles with behavior that we now deem unacceptable."

I thought it was Harvey Weinstein revelations that was the turning point.
My last few eyeglasses have come from Walmart. They know how to avoid the monopolist's prices, ironically. I got a pair of their cheapest frames, which were the ones I would have wanted anyway, with basic plastic lenses and no coatings. Total price I believe was $30.

Interesting! I'm glad to see so many people are willing to learn a new keyboard layout. I was looking at alternative keyboard layout for touch-screens for a while, and ended up coding my own. It's based on two-thumbs input and the layout is designed for alternating between them. There are only 5 buttons on each side/thumb so you don't really miss. You can swipe for special keys like enter, backspace, symbols, emoji etc, and so you should have the whole input spectrum available.

I've used it for over a year now. My friends beat me when their dictionary is on. But without it, I'm around 30% faster. For writing commands, code or formulas - it's superior, and that's why I like it.

It took me about 3 weeks to get on par with a normal dictionary-less QUERTY. Learning new layouts like this takes really long as it has to go into your muscle memory before you feel comfortable. I guess that's why we're still stuck with QUERTY (which was designed to slow down typing on mechanical typewriters).

It might be worth checking out for the technically-inclined. It's open source and as far as I know - patent free. See https://github.com/Adellica/Thumbkeyboard.

Good talk!

So, one question: Adam gives one example of a proof where the initial automation fails because it does not consider a theorem that was previously proved. He also gives an example of some complex code where the proof is too tedious to do without lots of automation. What happens when your complex code changes in such a way that you need some extra lemmas but don't know what they are?

Here's my hypothesis: The problem with these static verifiers is that they are applied at the wrong stage. The verification logic would be more useful in more cases if it were applied at the optimization stage.

Right now the benefits of static verifiers is rather binary. Either your program (or code unit) is sucessfully verified or it isn't. And every time you make a change to verified code you risk losing its verified status.

Imagine instead writing code that is made "safe" using run-time asserts everywhere. Unoptimized, this code might be slow. And unreliable in the sense that a run-time assert could fail, requiring some kind of recovery or abort action. But it would still be "safe".

The run-time asserts are effectively the "program specifications", and the discarding of those asserts at the optimization stage is basically equivalent to traditional static verification. The difference being that not quite fully optimized "safe" code is generally more valuable than not quite fully verified (and therefore not fully "safe") code.

> These heady days of being able to deny responsibility and shove out any software we want without consequence need to end.

If the static verification community is imploring the development community to, with some effort, change its practices to improve code safety, would that community be willing to, with some effort, move the application of their verification logic to the optimization stage where it would be more practical for a wider range of applications?

Pictures of the room with curtains were posted, then arriving to a room without them, with attendant privacy issues... false advertising.

We'd already been told that we'd get a negative review if she left anything, as we'd already tried to go through the 'dispute' process with airbnb.

Claiming a working TV and showing pictures of the main living area with curtains, then having neither is, at very least, deceptive. A broken shower (with video proof) apparently isn't enough to justify any dispute at all, because it was "fixed" on the 4th day. I would think, would be an admission that there was an actual problem that needed attention, and some sort of adjustment would be appreciated/welcomed.

Hangers - totally minor, but having emailed the 'hosts' earlier, they'd indicated this would be something provided, and it wasn't. I don't know how many things need to be a) promised in writing or in photos then b) not delivered before some notion of "goodwill gesture" becomes appropriate (10% off future airbnb booking? 10% refund/adjustment for poor service?) Apparently we were not even close to the threshold, and if that doesn't qualify, I have no good reason to consider airbnb for future travel needs.
I did my MSc in Data Science dissertation on classification of fake reviews - I never looked at Fakespot in depth, but my cursory gut feeling is that ReviewMeta.com is better (their blog is helpful). The problem in general is pervasive across all review based sites, like Yelp and TripAdvisor, but as the top poster points out, Amazon benefits from being a hands-off middleman, so they are not going to bother dealing with any problems until it becomes a PR nightmare.

If anyone is interested, you can find my dissertation at: https://douglas-fraser.com/datadata/

Only text based features were used, nothing involving other types of signals like reviewer name or spamming groups. I started out with 180 million Amazon reviews from 1997 onwards... but that got too big of a project, so the dataset used was a test set used in a lot of research on this topic.

I will be expanding on the research in my blog, examining other sets of text based features I never got the time to use, and things like PCA as well.
I think the idea that Scott Adams is 'promoting trump' isn't helpful on a number of levels. He is very, very perceptive about humans and their failings, and brilliant at lampooning corporate and bureaucratic group cultures and rat races.

I've learnt a lot reading his articles about the way the current crop of republican politicians are operating. He is one of the few people making sense and understanding the zeitgeist of half the American people. I'm not a trump fan fwiw, you can take this more in the Sun Zu sense:

“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”

Statistically significant is the difference between this med really works versus it's a placebo/not sig enough."

Nope, you are making at least two errors here. You can search for "statistical significance vs practical significance" and "research hypothesis vs statistical hypothesis" to learn more.

That is a confusing topic though, it would be best done away with altogether like this course appears to do.
I had to double check I wasn't reading The Onion. Sure, public water supplies in developed nations aren't without their problems, but I'd sure as hell prefer to take my chances with municipal "processed water" than put myself at risk from cholera or other water borne maladies that we more or less eradicated over the past 120 years.

I thoroughly recommend "The Blue Death: The Intriguing Past and Present Danger of the Water You Drink" by Dr. Robert Morris [0]. Kinda feels like these quacks need to be reminded of the life and death lottery our water supply used to be.

Most near-sighted developers would benefit from single vision readers with a focal length and PD (~3mm less than binocular distance PD) customized for the distance of their desktop monitor, laptop or tablet. Now that a complete pair of glasses can be obtained online for $20-$60, there is little risk in trying "computer glasses" and seeing how your eyes feel.

Some optometrists add +1.00 to your distance prescription to obtain your computer prescription. Some perform a separate eye test at laptop/monitor distance. There's also a calculator here: http://computerglassesrx.com

If you wear contacts for hours at the computer, you can try cheap drugstore reading (plus) glasses over your contacts, close to the +value from above calculator. Once you know what strength works for you, buy better quality readers from sites like readers.com, peepers.com, etc. Or make custom ones with your near PD and preferred frame at Zenni, EyeBuyDirect, etc.

Macroeconomics novice here.

From what I can tell, these two economic theories rely on competing assumptions. Keynesian economics is the theory that results from assuming the size[0] of an economy will closely follow the amount of aggregate demand. Neoclassical economics is the theory that results from assuming the size of an economy will closely follow the amount of aggregate supply.

In microeconomics there is no such duality. Rather, there is an understanding that supply and demand are each elastic with respect to one another. We measure this and reason amount markets while thinking about two explicit quantities: the elasticity of demand and the elasticity of supply. The two numbers (and the ratio between them) will tell you a lot about the effects that various conditions will have on a market.

My question is: Is there a corresponding concept of e.g. "the elasticity of aggregate demand" in macroeconomic theory?

If so, could articles like this be made more objective by providing concrete measurements of this figure on some time scale, rather than subjectively stating things like "Keynesian economics is hot again"?

If not, what prevents or complicates the existence of such a quantity?

I had trouble reading it period. It was overflowing with superfluous flowery prose, in other words[1], it was too wordsmith-y for its own good. It's a HuffPost piece about the advantages of buying glasses online in 2017, it doesn't have to sound like a tabloid magazine article from 1896 to draw in the modern reader.

[1] It was at a point early in the article where the author felt the need to say "in other words" and provide a dumbed down version of his previous sentence that I decided to stop reading for my own sanity. Next time, leave the thesaurus on the shelf please.

Lying may be common, but it isn't universal. I never understood why you would want to make a habit of having to waste memory and mental effort to remember the map of what lies have been told to which people. It's hard enough to remember one version of reality.

Regarding social consequences: I'm not sure. I was already a socially awkward nerd, which makes makes it very hard to isolate any lying/not-lying consequences. Politely declining to answer when a lie is socially expected (or, when possible, finding a way to respond that doesn't require lying) has worked out reasonably well so far.
No.

To the folks in power, you are the "other". You are a completely different group - even if your skin color is white. They can tell by your mannerisms, priorities, and dress you're not one of them. Indeed, they might say you don't work as hard as them, and call you "white trash" for shopping at Walmart. Even what I though was my high paying CS job was for the working class, no more a person than an MRI machine.
That seems incredibly cheap (in a good way). Almost too good to be true but I'll definitely look into that for my next pair.

The methodology shows the position of power that companies collecting data inevitably leverage:

Tinder doesn't supply any statistics or analytics about member usage so I had to collect this data myself. The most important data I needed was the percent of men that these females tended to “like”. I collected this data by interviewing females who had “liked” a fake Tinder profile I set up. I asked them each several questions about their Tinder usage while they thought they were talking to an attractive male who was interested in them. Lying in this way is ethically questionable at best (and highly entertaining), but, unfortunately I had no other way to get the required data.
