And sometimes it may very well be the same product. Expensive alcohol, clothes, handbags, etc. are very often bought as status symbols - i.e. as evidence you can afford to burn all that money on what's at best an incremental improvement over the mid tier.

Still, that's something entirely different than straight up lying about the objective qualities of your product. Especially medically-relevant ones.

In all seriousness, for that coronavirus mention, I'd like to see someone jailed.

I remember reading about a guy who did just this (eat bacon every day and only bacon) and lost a bunch of weight. I can't vouch for the truth, safety, or context of this though. Googling turns it up, fwiw.

I biked to work in a much hotter climate (DC area) and managed to survive by getting to work at 8am before the worst of the heat set in.

The afternoon was quite hot, to say the least, in the summer though.

I don't get this. Python is open-source. Surely volunteer programmers don't need the blessing of Guido to continue working on Python 2. And surely the number of people who are still using Python 2 somehow indicates that there will be some people among them capable of updating and maintaining Python 2. I don't think time is "running out" at all, at least not in a sense that is meaningful to people still using Python 2, after this many dire, repeated warnings to switch now.
Can you please share which major participants have withdrawn from the event? Where might I be able to look that up? Thanks.
You are wrong in several ways.

1. You literally cannot prove this fact from the Peano axioms because Peano arithmetic operates on natural numbers, not integers.

2. As I said in my original post at the top, negative numbers are different from the unary subtraction operator (the additive inverse in the field). The number -2 is an entity that exists by itself regardless of whether you've defined an additive inverse. It turns out that the additive inverse of every positive integer is the corresponding negative integer, but this follows from the definition of +, not the other way around.

3. Even if you give OP the benefit of the doubt regarding his dodgy proof, it is saying something about the additive inverse and its relation to multiplication. It is not saying why the result of multiplying two negative values must be positive.

4. The multiplicative operator over the field must already be defined for you to be able to prove distributivity over addition. You can't assume distributivity over an operator that is only partially defined.

--

Think about how you'd define a field. First, you need a set (let's call it Z), then you need two total operators over the set (+ and ), and two elements of the set (0 and 1) and each of these must satisfy specific properties (aka the field axioms). In particular, + and must be defined for all members of Z, not just Z+ and further + and * must be distributive. These are all facts you need to prove about Z, *, +, and 1 and only then do you have a field. You cannot work backward by assuming the field axioms (which are unfortunately named because they are not axioms at all but properties) to derive the definition o the field operators.
Ask HN: Have you observed any Covid-19 related panic buying yet?
I'm based in Scotland, UK.

We haven't officially reported any infections from COVID-19 yet and currently there doesn't appear to be any panic buying.

I went to three separate retail districts:

* The first one is predominantly a discount / family retail park. Shelves were at about 80% stock in the afternoon, and staff were actively restocking.

* The second was a large supermarket (Tesco), this was in the evening and despite being busy, it was still well stocked.

* The third and final place was a town centre, with many small shops (pharmacies, kiosks and grocery convenience shops). Some were low on daily sundries (toilet paper, ready meals, milk and bread). Perhaps because it was local, its just lazy people.

So, what have you observed in your corner of the world?

When responding please try in this format, so we have useful data:

* Location

* Area type (urban, suburban, countryside, very rural)

* Shop type (bulk, megastore, supermarket, retail park, medium / small)

* Water supply - high / low

* Food supply - high / low

* Sanitary supply - high / low

I don't think it's a "gotcha question" to ask how ideological claims are tied to reality in practice. But lets keep it high-level as you desire.

First, you describe a "key contradiction" that the capitalist economy as a whole would operate differently from a corporation. But it's unnecessarily reductive to demand such consistency. Ideologically a corporation is closer to an individual actor than to the overarching economic system imposed by government. In practice corporations grow from a single individual to huge conglomerates on the merits of their market performance, not from threat of violence, monopoly on employment, or other political power.

Second, you claim, "large corporations never make use of the mechanisms of capitalism, instead relying on central planning," which is a bold claim requiring evidence. There is tons of autonomy granted across the levels of a corporation, and a long history of conglomerates and franchises that cover the gamut of such regimes. If all of these are "central planning" then you need to explain what the alternative would be, otherwise its just a hand-wavy no-true-scotsman claim that can't be meaningfully examined or discussed.

You may be on to something there. I lowered carbs to well below the typical American diet, but nowhere near were the popular low carb diets go. I aimed for at most 40% of calories from carbs, and actually came in at 30-35%.

It's perhaps not as easy as a yes/no list, but 40% is very easy to figure out from the nutrition label:

max_carbs = calories x 1 g carbs / 10 calories

For example, a Sausage McMuffin w/Egg at McD is 480 calories, so as long as it has no more than 48 g of carbs, it's OK. (It has 28 g).

Make every item on your meal satisfy the 40% criteria, and the meal as a whole will.

Slightly up the effort scale, you can keep a running total of how much you are over or under for the day. Say you are going to get the Sausage McMuffin w/Egg for breakfast. That puts you 20 g of carb ahead. How about adding some McD Donut Sticks to the meal? 280 calories, 33 g of carb. That's 5 g too many carbs for the item to be 40%. But the McMuffin is putting you 20 g ahead, so losing 5 g won't mess up your overall meal. Go ahead and have those Donut Sticks if you like them.

We had this problem in Slovenia — cars chasing yellow and thus creating unsafe intersections.

Solution? Yellow means stop. If you run a yellow it’s the same as running a red.

You can only run a yellow if you’re already in the intersection when the light turns.

Despite the groaning and complaints from motorists, pedestrian impacts and high speed intersection collisions have dropped dramatically.
There are these decals you can buy on Amazon that fully or partially block out the light. They come in a sheet with varying shapes and sizes.
If anyone is interested in a framework that tries to put rigor into this otherwise very open-ended problem of defining consciousness, the integrated information theory (https://en.m.wikipedia.org/wiki/Integrated_information_theor...) is one approach. Problem with a "traditional" philosophical approach to consciousness is that it's hard to prove and equally hard to disprove. And although integrated information theory starts with the assumption that "consciousness exists", and builds on top of that assumption, at least it's a step in a direction where the problem of consciousness is turned into a measurable property. After all, even the most rigorous of natural sciences rest on some axioms. And I am not claiming that integrated information theory is in any way correct (although it may be). But theorizing about consciousness without a tangible logical framework always feels like it's not going anywhere, so I welcome the pursuit for scientific advancement in said theory
Considering the conclusion that

> The response to the abuses identified in this report should not involve a knee-jerk rejection of Uyghur or Chinese labour. The problem is the policies that require Uyghurs to work under duress in violation of well-established international labour laws. It is vital that, as these problems are addressed, Uyghur labourers are not placed in positions of greater harm or, for example, involuntarily transferred back to Xinjiang, where their safety cannot necessarily be guaranteed.

I really don't like the parts of this article that don't clearly distinguish between companies employing Uyghurs, companies using forced labor and companies treating their employees like shit regardless of ethnicity.

E.g.

> a September 2019 report by New York-based China Labour Watch said contract workers at Foxconn’s Zhengzhou factory—which includes Uyghur workers—put in at least 100 overtime hours a month.

is not a forced labor problem if their Han workers also work that much. If that factory decides to implement a policy of not hiring ethnic minorities, as some do (I've seen job ads explicitly excluding Uyghurs, Mongols, Hui and Yi) that doesn't solve the underlying problem that the factory is grinding its workers to the bone.

That's actually low! Most of the Universities we've explored research grants with wanted 45-65% overhead for the university, then another 10-15 for Research organization, with the remainder sorted between the researchers / company. We found it was actually just cheaper to pay for the research ourselves and hire the students directly for part time work than go through the grant process.

I sat on a couple school boards for a while, all that was ever discussed was fund raising and how we should be contributing more. Very little focus on education. Sadly it's turned me off spending time with Schools and just targeting students / researchers directly.

Gurdjieff presents a world system wherein (I am paraphrasing and
condensing wildly and inaccurately here) the human isn't born with
a soul but must construct one during it's mortal lifetime or "die like a
dog" leaving nothing behind.

There are (in this world model) three kinds of matter: terrestrial matter
(of the Earth), stellar matter (of the Sun and solar system) and
interstellar matter (which is stable outside the Sun's heliopause.)

The process of constructing a soul proceeds in two stages. First one
"coats" the physical body through and through with a stellar matter to
make the "second being-body", and then again with interstellar matter to
make the "third being-body" or soul. This third body is stable beyond
the solar system and, importantly, beyond the death of the original
physical body. The second being-body is not stable on it's own without
the first or third bodies.

I bring this up because it's a fascinating (IMO) third concept besides
"humans do not have souls" and "humans do have souls": "humans are born
w/o souls and must make them themselves before death".

It also makes a kind of sense that, in order for your human consciousness
to survive the death of the body, the material matrix within which and
through which your human experience carries on, you need another
nearly-identical body made out of more durable stuff.
In the US you can basically lie about anything and it's fine. If it's a relative statement, no one can disprove it. If it's an absolute statement, then it's on the consumer to know that it was supposed to be hyperbole or whatever and not an actual statement of fact.

Even numerical specifications can be blatantly fraudulent and it's still fine - eg "6.0 horsepower shop vacuum". A standard wall outlet cannot supply more than 2HP, but manufacturers have devised this outlandish "test procedure" that produces the bogus number. Still, zero prior restraint. The best enforcement we can hope for is a class action lawsuit in a decade where everyone will get a coupon for five dollars off a new shop vac, and the industry will move on to a new fraudulent measure.

My "hyperTeX" documents under NeWS looked pretty much the same on screen as printed, modulo hyperlinks, but I wouldn't want to write documents directly in PostScript. I'm unconvinced generally about the trades-off of markup in a non-macro programming language.

Incidentally, the nascent web looked horribly primitive when you already had fairly rich networked hypermedia and missed the significance of the web architecture.
As an IT college teacher for 21 years, I can tell you that educational institutions are very angry about this change. We often have courses that map to Microsoft certificaion. Students write them, and employers want them. They are a general benchmark that allows organizations to narrow the list of candidates they interview for a job related to one or more technologies. Most college grads get jobs in small-to-medium organizations where Azure is not a common requirement. Moreover, many small organizations that moved their stuff to Azure at the request of an MSP are current moving it back on premises to save cost now that they realize it's much cheaper to do so. Together with Microsoft's abrupt replacement of the Win10 certifications last year (they gave no notice to colleges or publishers), it looks like the trust colleges have placed in the Microsoft certification program is disappearing fast.
Out of the frying pan and into the fire? With it's wars causing the deaths of millions in the middle east and its excessive imprisonment of people for using near-harmless drugs, maybe the US is worse than China on human rights.
> The hospital has told reporters that the bill was sent in error
This problem is further exacerbated by the fact that we go through traditional education by default. A system that’s not designed to teach independent thinking but rather to reward obedience and implementing rules.

Not only this, but it baffles my mind that most (high-) schools put (interesting but almost completely irrelevant) subjects such as literature, comparative studies, dead languages etc. above skillsets with massive real-life relevancy such as financial literacy, programming, psychology and leadership.

The world's school system is completely and utterly broken but everyone's just too busy with their own BS to change it. It's heart-breaking.
We're working on an internal platform. Object storage, structured or unstructred data, plug-in architecture and easy to add applications. Notebooks with GPU and a choice of images with lots of pre-installed libraries with one click. i.e: our people will not have to deal with CUDA and won't have to get a powerful machine.

One click publishing of an automatically parametrized notebook as an application, an AppBook, without the widgets code or tagging cells. Automatic tracking of parameters, metrics and saving the models in object storage with no boilerplate code behind the scenes, so people don't _forget_ to log.
You can send post requests to your instrumented training notebooks and programmatically tweak training parameters. You can also have a runtime notebook with the params you want and Publish an AppBook so a domain expert can either try to validate it entering values, or train models themselves tweaking parameters.

Also one click deployment that gives you an endpoint to serve your model. You can invoke the model with a post request using an authentication token you can generate from the application.

We're adding functionality for projects and better user management, and supporting more data sources (for now S3 only, but Google Cloud Storage and Azure in the pipe). We don't have async training or invocation yet.

We're opening it for about 30 students of one of our colleagues so they could prepare their masters on an instance we deployed on Google Cloud Platform and pretty big datasets for students (they get to use a Tesla K80, which they couldn't before).

If you're interested drop me a line. We're also supporting the fast.ai course so people could start learning hassle free.

We have worked as a consulting company in ML projects with large organizations and we've suffered though the usual problems of config, hardware, libraries, dependencies, notebook sharing, model deployment, building applications from problem and model to the javascript on the front. Not trivial to find or keep people who can go through that, and it's tricky to need such people, and as a small consulting company doing contract work, the spending of having full time specialists if you can find them is draining. We also had the issues of key people not being part of the projects anymore and no-one knowing what the project was about. Now we're adding features for collaboration and institutionalizing knowledge of the projects, as we do in our software engineering day-to-day where we're all aligned and everyone knows why something was done -rationale, assumptions, hypotheses, etc.-.

So we built this tool to give us leverage, allow our data scientists to deploy models and share interactive notebooks without having to write widget code, or ask people who can deploy something to take care of it. Must be one click.
they do explain quite well why they picked what they did, and the blueair 211+ is their upgrade pick for bigger rooms. at least they publish their test methodology and results, so you you can make up your own mind based on the data.

Making a list of questions is the easy part. There are intricacies to all of them. Understanding that is the hard part.

For those with an advanced degree in statistics, what % of DS interviewers remotely understand the questions they ask?

I was great at interviewing. Then I took the time to really learn it, and made myself unhireable. So now I moved to a field where I am ignorant, and everybody seems brilliant again.
Another possibility would be to grind up olivine and spread that on the field. Olivine is a nesosilicate (orthosilicate) so it dissolves readily in weak acid conditions. And it's typically a few tenths of a percent nickel.

The dissolution of olivine would liberate magnesium ions, which could react with water and CO2, permanently sequestering the CO2 as carbonate.
