I can tell you that most major retailers (target, walmart, etc) most definitely have a system. It not only specifies which aisle to put things on, but exactly which shelf, and how much space is allocated for that product. I can't remember what they're called, but they're required for every product sold in those stores. When I worked at Walmart in college, we were issued these plans weekly. Obviously this is probably not the case with smaller retailers.
It is simply not true that big tech companies hire almost exclusively from world top 5 schools.

I'm saying "don't give much credence to an immensely popular and powerful basketball player about work, because he is an outlier of outliers". He could have been an immensely popular and rich plumber for all I care, I still wouldn't put much weight to the fact that he "liked work".

High-school and junior-league football involves far more participants, at much greater risk, due to their still-developing bodies and brains, with much less ability to make wise decisions about their long-term health.

There are lots of niche operations, but they tend to build their domain-specific work on top of these cloud providers.

AWS's fork of Elasticsearch (ES) is a good example of the operationalization you talk about. If I was building a niche eDiscovery solution for the compliance market on top of ES I'm likely to want to offer that on AWS or another cloud provider at some point. If they offer their managed version of it, then I don't have to support it.

You can make obvious arguments like special extensions, or all compliance customers don't use the public cloud, but ultimately many users are going in that direction. Any type of general-purpose tool like ES is ripe for the picking by any cloud provider when it gets popular.

The only options I see are licensing it in a way that's prohibitive for adoption by cloud providers, or engaging them early to become their subcontracted maintainer for the product on their cloud so that you remain in the value chain.

Ultimately, it's not the type of business that should be taking VC money because the upside is, so limited when you have the typical successful outcome. The only way to get to an outcome that VCs might like is to use the income stream, or talent acquisition, from the open source product to pivot into something that isn't as limited. Doing that is really hard.

Ask HN: Is burning trees for energy a sustainable source of energy?
This week Michael Moore promoted a just released documentary "Planet of the Humans" which is free on YouTube.

At 55m40[1] seconds the following unsubstantiated claim is made by a spokesperson from the Energy Justice Network, "If we cut every tree in the US (sic and used it for energy) it would only power the US for a year". The implication is that tree-based biomass power is delusional and the film spends a lot of time showcasing the spread and support of this delusion.

Below is an analysis of the claim above and using data from high ranking Google search results:

Trees in the US: 300Billion, average tree diameter: 14 inches, weight of a 14inch diameter tree: 1 US ton, percent of tree that is water: 50%. Average energy use per capita US per year: 11MWh.

That leaves ~1000lbs of carbohydrates (cellulose) for fuel which is ~450,000 grams. At 4kcal per gram = ~17kJoules per gram ~=> 7.6GJ per tree => 2.1MWh per tree.

So that's six trees per person per year. Not the ~900 claimed by the film. Given that it takes ~60 years to regrow a tree to 14inch diameter, we can grow trees much faster (3x?) than we cut them assuming energy use in the US stays flat which it has for the last 10 years.

Cutting down trees at mass scale is an unsettling thought, but that is not a reason to reject a mostly carbon neutral fuel source if it is a plausible intermediary solution and arguably preferable alternate fuel source.

Can anyone comment on why biomass/tree burning is such a bad idea given the discussion above ?

I'm not sure what you are going on about, you read far more into my post than I actually wrote. No policy action was promoted or implied.

My point is that the assumption that most small business owners will be able to reboot their businesses when the economic shutdown ends is almost certainly not true due to the mass destruction of their working capital. No one said anything about fairness or bailing them out, just about the unrealistic expectation that these people will be able to start new businesses, so that life will go back to normal for their customers, or that millions of people that have never run a small business will have a sudden desire to fill that gap. Many jobs will be disappearing as a result.

Another poster suggested what is likely to happen and I already see the wheels turning in my city: cash-rich investors/companies will swoop in to pick the carcasses of dead or distressed small businesses, acquiring the assets of the best ones at a steep discount to what would have been required pre-shutdown. That is a poor outcome for small business owners and will change their risk calculus going forward.

I've worked at two of "FAANG" and know enough people at two of the others (all but Netflix). The vast majority of Americans at all those companies went to mediocre public universities. (I don't know enough about foreign educational credentials to judge whether that's true of non-Americans).

The notion that FB/Amazon hire primarily from the top 5 universities is so totally unrelated to reality that I feel like I'm watching people discuss the consequences of the fact that the earth is flat.

It's unfortunate that classes are always taught as if they were a structure with some functions attached. That is one way to implement it. But object orientation is a philosophy or approach to abstraction, that's all.

But the array approach may may sense when some of the data are infrequently used. For example you could have a bunch of objects with people's names, ages addresses and favorite food. You may frequently manipulate or examine those names, ages and food preferences but only occasionally need the address. Your accessors _name, _age, and _pref may look at an instance variable while _address could look into the array.

Well protein production is regulated by other proteins that are indeed made from instructions encoded in the DNA. But you could imagine that a given cell has produced certain proteins that turn some genes on and others off. This pattern of control can be passed onto both daughter cells. This process is also somewhat stochastic, so not every cell in the population behaves exactly the same, so their daughters wouldn't either.

Almost makes you want to write a dystopian travel advisory.

Sydney, 2020. Foreign business people are advised to avoid all non-essential travel to Australia. Local authorities are known to seize devices, force self-isolation, force the installation of applications on mobile devices, inspect luggage and monitor the private telecommunications of travelers. Best practice is not to bring critical information to Australia and to use temporary or 'burner' devices where possible. Recent incidents[0][1][2] show a rise in anti-foreign sentiment, particularly for visitors of Asian appearance.

When I say 'tribes', I am referring to any ideological monoculture. Obviously some tribes are more adapted to local conditions. I would bet even the tribes you are referring to prioritise access to communications technology that allows them to co-ordinate their activities over distances that would have been unmanageable to them two generations ago.

If you scroll down low enough, you stumble upon per country multi-year comparisons. Notice how for Sweden, Switzerland, France or England the spike is not much higher than the seasonal 2017 flu.

Moreover the peak of the 2017 flu is cut out of the graph for France and England, as a couple weeks before/after new years are cut out from the graph for aesthetic[?!] reasons. For a publication that wants to be taken seriously, cutting out the most relevant comparison point is embarrassing.

And, of course, no breakdown by age.

the problem with quantum mechanics is that we cannot directly observe what is going on (and the instruments we use to do the observations are also subject to quantum mechanics effects), so to explain certain phenomena we have come up with different theories that approximate what is going on. These theories work for certain cases but nobody has come up with a comprehensive theory that can be experimentally tested and works for all cases.

Here is a few books you can read on the subject. They do a pretty good job on describing what the issue is and what the interpretations mean:

Max Tegmark - Our Mathematical Universe

Sean M. Carroll - Something Deeply Hidden

Adam Becker - What is real?

Here are some things you can google if you want to just skim the subject: Wave–particle duality, The Measurement Problem, Quantum decoherence, Copenhagen interpretation, Bell's theorem, Superdeterminism, Many-worlds interpretation, Ghirardi–Rimini–Weber theory (GRW).

Last but not least, look at the Wolfram Physics Project. (https://wolframphysics.org). The take on quantum mechanics if you go along with the idea of hyper-graph is fascinating (to me)

I don't disagree. I don't really know anyone working for tech companies, particularly startups. But outside of tech, everyone I know (in various sectors) has the same stories about their IT dept. So I think that this tendency to over engineer and deliver nothing is more than an isolated anecdotical experience.

3rd paragraph is the grovelling the school district needed to do to deal with the interference of the King County Health Department.

There is also the "red dawn" emails which clearly show that King County was not doing a single thing in the face of knowing it was a problem - Dr. Duchin (King County Health) on March 1st - not 4 days after this public rebuke of the school idstrict.

"We are having a very serious challenge related to hospital exposures and impact on the healthcare system. Would be great to have a call to discuss. Will be meeting with your team here this morning and then maybe we can chat after that"

So it goes from laughing to all hell breaking loose to doing nothing for almost 2 more weeks? That's the Health Department leading the way?

Do you have an axe to grind against the blog’s author?
I don't know how long ago "once" is, or how big this client was, but every modern large grocery company is pretty data-driven, especially about where products are placed. Lots of places have robots crawling the aisles in real time updating stocking information and taking video/images of product presentation on the shelves. They are presented as "cleanup robots" and they put googly eyes on them and a name tag or whatever. I even once asked several employees about them, and they just shrugged and said "yeah it's the cleaning robot." But it's a column 6 ft high it's not a roomba. It has a clearly visible array of cameras on each side, and who knows what other sensors.

Your replies are a mixture of "This sounds false - large supermarkets would have this data" and "This is just an ML use case" and i think both miss the point.

Work backwards from the customer need. If they truly need this system, and are willing to pay for it, then it sounds like what you need to build is:

* A database for product taxonimies/locations
* An internal tool to make it easy and quick for staff to go through and log the locations of products to build out the data model
* The actual maps UI and display tech.

The thing is, this might not even be that much work. It's all a factor of how many "categories" the store expects customers to be able to search for. If the granularity level is "pasta", you can probably get away with 100 entries, and 1 days of grunt work for a staff member to log the location in the store where "pasta" and "coffee" and "condiments" etc are.

This story is not a good example of a difficult customer or a difficult technical problem.
The devil is always in the details. Deciding who pays to host new platforms, who gets to gatekeep content, etc ad nauseum, would likely sink any such effort.

Frankly, that seems like a long way to go for what is effectively twitlonger. If you buy the premise that Twitter is effective at amplifying the right voices (very much still up for debate), and the problem is the interface for long-form content, then it seems to need a much simpler UX fix rather than trying to invent a separate-but-joined platform from whole cloth.
I can't make sense of what you're saying. You've completed the proofs when you've discharged all proof obligations. The proof obligations will depend on the formal modelling system you use (Event-B, say), and of course on your formal model. You aren't left in a state of uncertainty as to whether you've finished discharging the proof obligations.

Are you referring to the possibility of errors in your model? That's not the same thing.
