LOL I opened this thread just to post a link to the Quanta magazine site. It's a very well done article and applies a great human element to the story. Dementia is one of the few things that scares me.

For an amateur mathematician to do this is, as you say, a surprising feat. I'd go beyond that to add a bunch more superlatives.

It is stories like her story that serve as good reminders that the idea of citizen scientists is healthy and should be encouraged.

I highly recommend the link you provided. It's a bit long but well written.

How in the world is this kind of thing legal?
Good on you. If it's worth doing anything at all, that 'anything' has to be on a political level. Consumer action is a dead duck, albeit a convenient one for the green-hued sector of corporatocracy. Green parties have wasted enough of our time with it.

It's a shame so much political activism is protest rather than construction. That's probably inevitable given the configuration of political power and the sheer speed of the destruction (locally for example I certainly don't want the Adani lunacy to go ahead). And protest can develop community which can be a usefully subversive form of construction. But there's something slightly unsatisfying there, and it doesn't suit everyone's predispositions.
The bike is the most elegant mechanical systems in history, elevating humans from earth's least efficient creatures to it's most efficient.

Electronic shifting and other boondoggles completely undermine the reliability, elegance and simplicity of bikes.

I've fixed my bike while on the side of a mountain a hundred miles from home and ridden home.

What happens when my derailleur firmware crashes?
Sensationalist title indeed, still interesting though. Based on the author's previous posts it seems he has a distaste for Uber. I am curious to know why views them so negatively?
I have statistics. 2640 user accounts from 6320 orders.

Some customers are repeat customers, but even if we are generous and assume that the majority are not repeat orders (I'd estimate 25% are repeat orders), that's over 1/3rd that created an account even though I offer guest checkout without an account and don't really push them to create an account.
How to Rebuild Class Index?
Sure. But MongoDB is far better at scaling, has infinitely better drivers (including Spark) and is about an order of magnitude faster than PostgreSQL for partial updates.

The lack of a Spark driver alone renders PostgreSQL useless for most companies.
For most people, $500 would be taxed and $500 is then returned. So what would be the change?

I never liked Scoble, I always got a really weird vibe when I saw him live or in videos.

I'm really sorry to hear that this happened to Quinn, and many others apparently. I believe sanctions should be very strong. I really hope they are, it seems to me like this man should go to jail.
I think the author is painting this in the worst possible light.

The UX is a little misleading but I could see this being an effort by Uber to pre-commit drivers as a means of reducing surge pricing.

What makes this potentially unethical (in my mind) is where the price is set. If it's set at a point where Uber's models predict the average benefit to a driver is $0 then this is essentially shifting the risk to their employees.
The fact that this claim hasn't been verified by an external source makes me rather dubious. Most people with dyslexia are diagnosed when they fall behind their peers in learning to read. In a learning environment in which students have no real peers there is no measuring stick to fall behind. Any student who struggles learning to read is probably categorized as "learning at their own pace" rather than being diagnosed with dyslexia. That doesn't mean the student doesn't have a problem. The school is probably just unintentionally masking the issue with their teaching style.

I would be curious to see someone test a collection of adults who graduated from the school and to see whether they show signs of dyslexia.
If a city isn't already crowded then it makes sense for the residents to strongly oppose letting it become so.
Dollar General is a refinement of Ray Kroc’s McDonalds model for passive investors. Their magic is net leasing in shitty areas with barebones stores, so they don’t hold many obligations on their balance sheet, and don’t spend a lot on building upkeep and taxes. It is basically a ground lease and a bond alternative.

That works because it’s an investment that lets passive investors yield 5-7%, which is a good yield from a company with a good credit rating.

As rates rise, it gets less and less attractive, especially as leases start maturing, growth slows, and you need to put capital dollars into cheap buildings that you don’t own. It’s not a bad company, but it’s no Walmart.
I never understood why the banality that Scoble produced was so popular? It's been a long time, but I seem to remember most of his articles had the vibe of "I tried 25 methods to format my USB stick and <this one> is two seconds faster".

Anyway, I hope Quinn Norton gets all the support, kindness and apologies, she deserves. And that Scoble finds the catharsis he needs.

Which I have to say sucks for the rider behind you. If you demand that level of visibility get a high vis vest. Personally I err on the side of assuming every car will try to kill me. It's kept me alive in SF, London, and worse places where most people are scared to bike on roads for good reason (New Mexico).
I think this data is being very generous. The Tax Policy Center pins the 1% threshold at 750k+

FWIW, Shimano Di2 batteries have always been rechargeable.

SRAM's eTap wireless shifting system has a mix of rechargeable batteries on the derailleurs and non-rechargeable CR2032 batteries in the shift/brake levers.

I don't know what Campagnolo does, because I'm not interested in farm machinery. It is probably rechargeable by sending it back to an Italian specialist every two weeks. ;)
No, it's an inflation argument against UBI. If everyone has more money, everyone becomes less sensitive to increases in prices, and therefore prices rise into the new equilibrium. (Increase in demand without a corresponding increase in supply leads to an increase in the price level, in intro microeconomics-ese). Now, the price level may not rise to the exact level where it cancels out the entire UBI, but that's based on various factors that are effectively unobservable.

It's not quite thermodynamics, because it's not as strict of a 'law', but it's close.
> How many women do you have on the mod team, for perspective?

This makes an excellent point, and the same could be said of the junior moderation team - the HN readers who up/downvote comments.

A practical solution: The mods might ask people in underrepresented minorities for some honest, frank perceptive and feedback. Stop guessing and trying, and get some real knowledge. Look at particular threads (on sexism, etc.) and talk about how welcoming HN is to them and why. IME, there is no substitute for a lifetime of personal experience with these issues; most people without that experience - including myself - are surprised when they hear the realities and details.

You can identify who is underrepresented and who might feel unwelcome by what groups are referred to as "they". For example, in discussions of sexism women are often discussed in the third person - a good sign of who is the excluded group. If you think about it, those discussions should be led by the people who have experience with the issue, just like Java devs (hopefully) lead the Java discussion. This discussion, right here and right now, should have those voices - it's right in front of our eyes.

I'll add that religious prejudice against Muslims is particularly overlooked. If I were Muslim, I would not feel welcome here at all. As a practical test, substitute in 'Jews/Jewish/Judiasm' for 'Muslims/Islamic/Islam' (to pick a religious minority against which prejudice is rejected, as it should be for all) and evaluate the statement. I've seen many that unambiguously fail.
In Copenhagen people raise their hand to indicate a stop. I wish we'd adopt this in the U.S.
That's the SRAM system. Shimano has cables.

That said, I prefer my home built fixie: cheap to get great components, easy to maintain, and damn fun to ride.

It doesn't imply everything is discrete. That is a rather meaningless phrase: language is already discrete, so everything that can be described with language can be said to be discrete in that sense, including anything you'd think is not discrete. For instance, the topological notion of continuity is about preserving nearness which wouldn't say anything about a non-discreteness of elements considered. I'm struggling to come up with a proper notion of non-discreteness in the first place, since there are plenty of things known to be both discrete and continuous at the same time.

I would argue instead that the "discreteness of the universe" is not even a very interesting question to resolve. And in physics, it would need to have scientific verification. If you say space is discrete, then where is your minimum wavelength? How does the discretization of position relate to the discretization of angle? Etc.. It's not really about mathematics at that point, but about finding a physical phenomena for which this (vague) notion of total discreteness is relevant.
> Your parent commenter doesn't like Mongo. So it's not production ready.

Eh I don't like Mongo because I've used it. IDK, it's been a few years since I've had to deal with mongo in a production environment. I don't miss it. I dislike that it's slow to get data to/from the javascript interpreter -- and that the solution was to work around it with the aggregation framework.

I don't like the unsafe defaults (data integrity, access control).

I don't like the magical, unreliable sharding that you have little to no control over.
I believe the only practical approach is a positive one.

Lets assume we're going to survive climate change. After all, we have to.

And lets assume we're going to survive it without needing to go back to our pre-industrial lifestyles:

- we're going to drive around in our EVs, charged from renewable sources

- we're going to sit at home playing video games and living in VR (because that's a nice energy efficient way to spend our days)

- we'll hopefully have access to modern medicine and the other benefits of our existing economy

I think once we start viewing survival from climate change more positively, we can start making better decisions.

For example, if we're going to survive, do we want to do so inside some sealed dome, hooked up to a desalination plant, where our day jobs are manually pollinating the few species of plant that have survived?

Or do we aspire for nature to remain at least somewhat intact, and for our plants to be pollinated in the current way - magically, by insects?

Why the Email Confirmation Field Must Die
That's funny. The proponents of UBI would say that it in fact is the key to maximizing productive social behaviour.

Of course, it's a matter of worldviews. You might think innate human behaviour is laziness and only forceful contracts can get productivity out of them. I can certainly see evidence of that, but I don't think it's innate for everyone. I think many people would be eager for a sense of belonging and purpose that could only come from contributing to society.

Think about all the people that help out in times of crisis without 'reward'. That's also innate. Whether it's the majority, I think that's a matter of culture.

If you define the primary relationship people have to each other in society with forceful contracts, then yes, you might engender also a subculture of rebellion and banditry that results in laziness and exploitation. What if we defined it differently?

"I think the author is painting this in the worst possible light."

You should work for any sort of delivery or courier service. This 'worst possible light' is daily business for companies like Papa Johns and others that claim their drivers are merely 'contractors.'

This is also quite illegal - you can not pay to work. It's literal extortion - you have to pay us in order to receive this amount of wage. No, the courts frown upon this.
Since we're talking about it, are there any decent brands still making dynamo bike lights (the ones that are powered by the turning of the wheels)?
What I mean is it is no way those targeted programs can be replaced with UBI. If someone is getting 30k of value from an existing or existing welfare programs, cutting it back to 12k removes their social safety net, regardless of the straight cash they get. Worse, if they run out of that, they really have no safety net remaining.

> NoSQL really fits best around the margins, like as an auxiliary system for analytics.

I'd say it also fits well in two niches: document datastores (so long as there's some JOIN support, via referencing nested documents vs direct nesting) and graph stores.

I remember 10+ years ago working on storing nested sets in the RDBMS and it wasn't pretty. And the RDBMS schema for Magento 1, with key-value tables all over the place which NoSQL would have removed the need for.
But that suggest prices are set by the available cash flow. Which means without other factors if we just lower everyone’s wages to zero everything will be free. Obviously this isn’t the case. Also it completely ignores supply and demand. Under UBI someone will raise their price to take more profit... but then no one will step in and compete because they see an ability to offer the product/service more efficiently.

Seems this inflation argument against UBI has obvious limits. Maybe it could cause some but it can’t be a linear relationship as people like the parent argue.

Just as with many highly valued startups, you can think of WeWork as valued for the possible future business model rather than it's current one. If WeWork is able to transition to a business services company with essentially a captive market (its tenants), it'll be a very profitable company. Other such companies have a high customer acquisition cost. WeWork is betting it's more efficient to rent office space and have a mailing list than to pay Google for those same eyeballs.

If there's one thing to learn I think it's that men can do far far more (like the intervening guys in the article) to step in and be far less tolerant of such grotesque behavior.
