Population density helps with making deliveries more efficient, at least in urban areas. Just down the street from me there is a mini delivery center (just the 1st floor office in a regular building) where packages are sent before they are pushed out in carts to buildings in the surrounding area. The last mile is really easy when everyone lives on top of each other.

That said, it's not all perfection. Recently one of the large delivery companies had problems fulfilling all its evening delivery slots and the number of re-deliveries weren't helping. I think every building should have lockable delivery boxes at the front door as standard, then almost all packages can be left without customer interaction.
There has been an enormous amount work on battery technology for the last 30 years. Probably 99% of it leads to dead ends.

Standard rule of battery development, if everything goes right it takes ten years to market. And another ten to get market share. In the late 90's early 2000's there was paper after paper published on lithium iron phosphate batteries and dick all nothing for sale until ~2010. And ten years later market share is growing slowly.

There are also a ton of "studies" funded by various industry groups. In a lot of cases you don't even have to prove that your product is healthy, you just have to cast doubt on any previous research that says it isn't.

There is no oversight of supplements (at least in the US). You just have to trust the brand, because legally there's nothing stopping a supplement manufacturer from using entirely different ingredients from what is claimed.
There's a difference between displacing the local population (which you imply) and moving somewhere there's better opportunities (jobs, housing, &etc). As long as there's no coercion or violence involved then who's the victim if my new neighbor is from Guatemala?

Plus it'd be pretty hard to be an oppressive dictatorship (looking at you, California) if the people could just up and move to a less oppressive regime (like Arizona). Of course I'm (mostly) joking with my example but a CA->AZ mass migration is happening as we speak and nobody is calling for a wall on the border (yet). They can't put up massive apartment/condo monstrosities fast enough to handle all the new folks moving here and presumably they're finding jobs without too much trouble.

So, yeah, I think if governments had to compete to retain their "subjects" the world would be a much better place and people probably wouldn't need to relocate unless they really wanted to unlike today's multiple "migration crises" (their term, not mine).

They don't need to know which product belongs to which seller, they only need to know how many.

If someone clicks your listing and buys a product, they ship it from the commingled inventory and then pay you your share of the sale and deduct one from your inventory tally.

Then, if the item they sent ends up being counterfeit, whether from your own stock, from another seller, or even from Amazon's own stock, they will take it out on your seller account for selling counterfeits.
It was known to be bogus from the start, why look at patents?

But let's say this is a interesting path, only "competition research" can do it, since it's very highly specialised and Holmes alone had hundreds of patent in this one company of many in the field, which would take a lot of time to analyize.

Why would " a competition researcher" disclose after doing the millions of dollars work researching all the patents in the field? Surely this IP has more value internally.

It also would prove they are looking at patients, which won't look good in possible future lawsuits from any company on patient infringement.

That's my life, over 10 yrs w dev experience and still hard to get hired or make over $24k a year. Luckily I saved money living at home and could afford to be unemployed, so now employers think I'm lazy for taking some time off work.

>They must be partial to Infosys. I mean, what did it do. https://www.myvisajobs.com/Reports/2017-H1B-Visa-Sponsor.asp....

I am not quite sure if LCA is an accurate metric of visa count. For example, I had my visa renewed 3 times so far. Every time, they filed for an LCA. I had to relocate one time. For that also, an LCA was filed. Then another one for my green card PERM or I-140 stage. People who come from India and work for TCS, Infosys etc end up relocating more often. Also, unlike American companies, visas are given to Indian companies only for 1-2 years and sometimes even less (American companies usually get for 3 years). Further, 25405 number doesn't mean they all were deputed from India. Indian companies hire a lot from US. They actually prefer hiring these students because they are desperate for a visa and are willing to settle for a lower salary. If they have to bring someone from India, they have to file the h1b application, hope they get into lottery and then only they can even think of putting them in a project. Most clients won't even want to wait that long unless they had been working on that project for a while and has acquired good knowledge. Where as for students, they can hire them, and file for h1b in the next few months (students get upto 18 months of something called OPT that allows them to work without h1b). This is precisely what's happening in my company. Same I heard is the case for Infosys. And these companies also hire people who are in the green card queue.

>Right, the startups in bay area, good groups at Apples, Googles and Facebooks of the world are filled with people from Infosys ;)

100 thousand Indian students come to US every year. How many of them end up working in these companies? Your own list shows less than 15k.

Among the deputed ones from India, the good ones never stay in the likes of Infosys. While I don't know anybody who went to Google or Facebook, I know a few who jumped from these Indian consultancies to Amazon, Intel and few other Silicon Valley companies. So, I don't think its fair to dismiss a person working for an Indian consultancy company as incompetent. My friend in Infosys was saying recently that a lot of people are joining Amazon and a few other companies like them these days. They can't be stupid if they are getting hired in these companies, right?

Also, I was recently talking to 2 of my friends from Infosys on 2 separate occasions. Both said there teams were trying to hire people locally (Americans), and both had the same opinion as you about the people who came for interviews about skills and competency.

> If anything, most of the technically competent desi people in US have a US degree.

I actually developed a bad opinion of them based on their performance in my own company. People who end up in good colleges probably are good. But those who come from tier 2 and lower colleges are not going to be good just because they studied in a US college.
Amazon, with all of its technological and operations might, is pathetically terrible at their own last mile delivery operations (I'm going to discount them hauling trailers from distribution centers to USPS sort facilities; anyone can do that). To displace UPS and Fedex, you would require immense amounts of capital for your delivery network, and staff properly compensated and treated well for quality work (ie a union or benefits of sufficient quality, a union isn't required).

Arm chair "logistics experts" should go sling packages for a few weeks to see what it takes to compete with real operations before declaring existing operations dead if they don't "disrupt themselves". UPS, Fedex, and USPS aren't going anywhere.

I’ve taken to using shipping depots for amazon shipments. There’s a 7-Eleven just down my street that I can ship things too and pick them up at my convenience. It’s easier than missing the delivery guy and dealing with redelivery, or worse, going to the UPS centre and getting it.

It shares a property with phi which no other irrational shares with it (They are known as the only two Morphic numbers, which one must avoid confabulating with a similarly named concept whose name I can't recall right now.). And Knuth liked it (well, the reciprocal of it's square anyway, albeit the cubed version seems more interesting to me.), but never found any application for it. (He even made a special TeX symbol for the square of it, 'High Phi', see Wikipedia for details.)

Why is it socially correct to not automate?

I’m genuinely curious to hear this point of view. I don’t believe unskilled labor (or minorly skilled labor) has a right to a job anymore than a very skilled laborer does.

There’s a reason why cement trucks were created when you could (and can) still mix cement by hand. It’s wildly inefficient at a certain project scale, and I hold the same view for other items.

I’d love to know why you feel it’s socially wrong to push forward automation.

This is no way correct. The employees file their own returns just like any other American. And they get paid the full salary mentioned in the offer letter they received when they were deputed.

The only "violation" I know these companies do is that they make the employee sign a bond that they have to come back to India and give a 3 months notice period if they want to resign while in US. And this is not just Indian companies. I was surprised to learn recently that the Indian division of an American product company (top 1 or 2 in the world in what they do) has a 12 months notice period with around 10 lakh rupees bond. Compared to that, Indian companies are less evil.

Another thing the Indian companies do is make you work on less desirable projects or otherwise you have to go back to India. And they don't treat their employees the same way a product company in America would do. They see us more or less as "you should be grateful to us that we gave you chance to come to US".

C's Standard Library doesn't suck, and, in all my decades of programming, I did not hear that statement at all.

The standard library just doesn't give you much. Things have gotten better with C99 and C11, but there are many things that every day programming depends on but are not covered by the C standard library. Simplest example: Traversing the filesystem. You can easily come up with other examples.

Can someone compare their experience with Flutter or even React Native, versus writing separate platform-native Swift/Java versions for iOS and Android?

I don't often hear about the true accounting of time spent learning and grappling with the limitations of cross-platform frameworks, including debugging and workarounds, versus just using the platform vendor tools.

It just sort of seems like it's assumed that it's a huge time waste to maintain separate codebases. But I wonder if you gain other advantages that might outweigh it, like not having to "fight" the intermediary layer and getting first-class access to the underlying APIs, platform features and debugging tools. Thoughts?
Yes, the materials issue is usually the root of the problem - weight vs. strength vs. durability. (I expect that manufacturing to the needed tolerances is pretty hard, too.) Modern jet engines are so optimized for these factors, and also for fuel efficiency, that the same general designs are now used for power generation on the ground, where things like weight don't really matter.

Is the source code Open Source?
Yes, but it's also important to understand what you lose when using these better-performing hashtables.
First thing that comes to mind is that when performing a successful lookup on a std::unordered_map, the reference is guarrantied to be valid until either (a) you erase that element or (b) the table itself is destroyed.
Almost all faster hashtables around give up that properties for better lookup performance. Any insert operation might break all references.

So, in a sense, it's a bit unfair because std::unordered_map, in a real-world scenario, will potentially require you to perform less lookup because you can cache the references. With the others, you can't.
That's not my understanding.

At least in California AFAIK the law says exactly what the poster above said which is that the company owns work related their area of business even outside work hours and not on company equipment.

I always think of it this way. You're at dinner (ie, off company time). While a dinner you think of a solution for something at work. Do you own that solution? Can you charge the company $$$$$ to sell them this solution you came up with outside company hours?

If yes then there's an incentive for you to never think on company time. If no then it seems pretty clear there's a spectrum from clearly related to the company's area of business to absolutely not related to the company's area of business. If you work at Facebook and on the side you design a new IoT coffee maker that's probably on the unrelated side. If you work at Facebook and on the side make a new social networking site probably on the absolutely related side.

If you want to be safe rather than wait for a court to decide get it in writing. At least when I was at Google they offered that service. You could bring them the idea and they'd tell you if it was related or not and if not give you a signed contract saying they officially had no interest in your outside project.
Yes, but at least you can trust the brand or not at most brick and mortar stores.

On Amazon, you can buy your trusted brand and not actually be getting that brand.

Granted, this happens at brick and mortar on occasion, but they generally have a relationship with most of their suppliers and it would be unwise to allow counterfeits through.
TL;DR IOWs, you need to understand how computers work.
Maybe I'm speaking from ignorance so please show me why if this is wrong, but I find physics to be much less understanding the universe than observing it (and happening to be able to use the language of maths to describe those observations).

The naturalness/beauty described by the author is an approach which seeks to formulate theories which help us understand the universe.

Perhaos the apparent naturalness/beauty in the equations you state has less to do with understanding what makes the universe work, and more to do with our mind's predisposition that we would tend to observe those relationships first.

Many physical laws, AFAIK, appear less as absolute truths, or keys, to understanding the universe and more as just observations about what to expect. IE Newtonian gravity works all the time, is described beautifully in maths, but then at certain scales stops working. Does it really tell us anything about what makes the universe tick?

Anyways here is a clip I like from Feynman discussing the idea of beauty in figuring out how nature works: https://youtu.be/MEqMM2Co_9c

If you think "penny pinching short sighted know nothing accountants" are the cause of a small team, I think you perhaps don't understand the domain involved.

To borrow a popular phrase, modern jet engines are literally made of black-magic fuckery. The advanced metallurgy and fabrication techniques that go into their design and manufacture are such that even if you wanted to double or triple the size of one of those teams, there may simply not be enough people in the world today who have the requisite background. And it's also not a matter of "oh, just go read these papers and get up to speed"; the engine manufacturers derive most of their advantage from the fact that they can do things nobody else can do, and they don't publish all the deep stuff they know.

It's amazing to me that people still believe high blood pressure is some lifelong ailment you need to learn to cope with. Of all "diseases" it is pretty much the easiest to fix. It is well known that as short as a 8-10 day water fast is sufficient to drop any medication and restore a normal life, provided of course that you resume at least a somewhat normal diet and not McDonalds, high protein Keto crap, etc. It's really remarkable how such a "disease" can be sold to the public as a lifelong issue.
