For me it's that 85% of the time I use networking, you're using something that I learned by myself. But that 85% accounts for only 10-15% of the knowledge. So there are a lot of concepts that I learned in school (like DNS, link/physical layer, microarchitecture, etc) that I rarely use. But just because I don't use a lot of the stuff often doesn't mean I never use it. And even the things that I really never use (like programming an FPGA) aren't things that I regret learning.
I didn't say it should be the default, but yes it should be. It is for structs.

We can have giant structs. I've seen some over a megabyte in size. The default is that the callee gets a copy. (depending on the ABI it could be in the "wrong" stack frame, but it is a distinct copy)

Are we having huge problems with structs being passed by value? I don't think so. Normal people pass pointers, except when they actually want to pass by value. It works fine.

I have frequently seen beginners struggle with C arrays and pointers. Part of the trouble is that you can't pass an array. You can try, but the compiler quietly substitutes different code. It's a source of confusion, generating incorrect mental models of what is going on.

It isn’t really all that valid in terms of the $1.2k payout. That was at the height of the pandemic, you absolutely didn’t want to have people out working in infrastructure jobs at that point, you wanted them to isolate at home.

But the broader question, could/should the US use this moment of mass unemployment to create infrastructure jobs: IMO, yes. But it’ll never happen because someone will say the word “socialism” and it’ll immediately become politically unimaginable.
Maybe it's a similar kind of trend where women in western countries prefer non-STEM related fields on average as they have access to an abundance of more attractive possibilities. It's a sign of social progress, as twisted as it seems. Math is hard, people avoid it when they feel they can.

No. You always retain full copy right to your own works. You can choose to license your work to somebody else on arbitrary terms (like, for instance, the spite license), but that doesn't affect your right and ownership of the software.
You gotta be kidding. It's hard to find a company that innovated more in the last 20 years:

MapReduce, Spanner, Protocol Buffers, Gmail, Go Lang, Android, Chrome, Microservices, Borg, Tensorflow, TPUs, Google Maps, Google Street View, Google Docs, Google Translate, Dremel, Duplex, Chromebooks, ChromeCast, Daydream, mobile first development, BeyondCorp, V8, Kubernetes, LevelDB...

Those are just some of things I can think of from the top of my head and doesn't include the machine learning research that google and deepmind are doing.
I also disagree that Google are building a better browser - better at/for what?

That was always Microsoft's position ... to paraphrase ... "our stuff is the best, because the most people use it, (and democracy implies most popular = best)". It was a bulls++t position for MS then, and it's a bulls++t position for G now.

Like MS was, Google is very good at pushing people to their products and keeping people. They are rather poor at writing stable, efficient, useful software - Chrome and Android are HHUUGGEE, and routinely updated with new security flaws, new APIs that add yet more security flaws, and new bugs. The purpose of chrome or android etc seems to be to force people to use it, and to force people to stay on it.
Almost certainly with a controlling share held by SpaceX proper. Owning SpaceX will still be a strong play on starlink. They aren't going to just sell it off for chump change.
but where do all the resources for creating complicated technologies like chip fabrication and MRI machines come from? small start ups certainly can't, at least not for large scale R&D. only gov'ts and large corporations really can, and the latter only will if they have some guarantee of making a profit off of the work they put into the tec
I'm not sure. I think it's still too early for people to be comfortable going to open offices.

My company officially allowed on-site work again several weeks ago in NYC. I have one close colleague that tried it, and he was the only on in the office. I know several colleagues in small apartments that were not fans of not being in the office that have not returned yet.

Sure, more space at home makes it easier to drag this to the long term, but even people inconvenienced at home have found solutions for 180 days now, and aren't (at least with my company) jumping to come back.

Could you elaborate on a plan (of course a really rough sketch) for "creating infrastructure jobs" during a global pandemic?

I agree with the premise, but I would like to know how to accomplish something like this. Especially if you have domain knowledge, it could be enlightening to the HN readership. There are a lot of accomplished people who read these forums, and it would be cool to see a seed get planted.
For the same reason we weren't creating infrastructure jobs before coronavirus. I'm not specifying what that reason is, and not for rhetorical reasons. I'm not specifying it because the need for infrastructure investment was just as acute before covid as after, and it wasn't being done then, and won't be done now.

Universal handouts weren't to handle unemployment. They were to pay people to stay home.
You think that people are going to tell a government survey that they used the government check to buy televisions? :-)

Similar to will people who support either political candidates disclose it in an interview - especially if they live amongst a social circle that leans the other way.

This is one of the main reasons survey techniques are being replaced by observational and inferential techniques in market research.
Is some of this a failure to distinguish between software engineering and computer science? Some famous CS person quipped that "CS is no more about computers than astronomy is about telescopes." That's fine for studying applied information theory and whatnot, but it seems like maybe the time has come for a formal bifurcation of the fields.
Tell us all the answers, then, since you obviously have them.

“Dude” advised against going out and grabbing all the N95 grade masks, in order to leave them for healthcare workers, when Trump knew it was “airborne” but attempted to hide it from everyone.
Hmm, I think we're just looking at it differently. Why does fair mean "everyone is graded exactly the same, whether they're good at this certain type of problem or not"? Couldn't it be argued that the most fair way to judge people is to treat everyone individually?
The problem is that bankruptcies, starvation, inability to maintain your car/house/children/job, and businesses collapsing due to the sudden demand shock are all extremely expensive for the economy in the long run. Those types of losses which these universal handouts are intended for are quick to inflict and long to recover from. As an example, if your normally profitable restaurant goes under and forced to permanently close due to insolvency, it'll take years to build back up a similar restaurant with a similar rapport, client base, efficiency and success. The long term economic impact of these handouts would easily outweigh the infrastructure investments you are proposing.

When times are good though, we should be increasing taxation and investing in infrastructure. Instead, the US Republican party sought to create a massive tax cut during economic boom, which means that we are in a worse financial situation when times have become rough.
Open source hardware is also really good at allowing whoever can produce something cheapest to capture all the profits.

Unless the designers are careful about controlling the results of their labor they won't be the ones "thriving", or even benefiting. It only works in certain niches where the technical aspects of production or market naturally exclude most other manufacturers.

Or what about designers who don't necessarily want to be in production just to make money?

Ask someone who has spent years and thousands of dollars developing something only to have a copy shop in Asia start selling their widget for half the cost a month after the design files get posted if they think that's a sustainable business model.
Second Wave of Floating Storage Triggered by Ailing Oil Market
Fusion power is not a replacement for solar. It is the technology that needs to be working in the next two hundred years if we want to see society continue on its current trend. It may be the difference between human society lasting billions of years or being a small footnote on a single planet in a dark universe. We’re already stuck with bad climate consequences. We might not destroy the entire habitat or run out of usable fuel if we stop penny pinching and actually pay what’s needed to solve a problem far harder than something like LEO launch vehicles.

As for breakeven: no plasma physicist I’ve talked to see it as some amazing barrier. It is what it’s always been: a publicity thing. It gets people excited so laypeople can point and say “See! It works!” without having to dive deep into physics and economics. The real physics goals of ITER are in testing models when pushed outside of previously measured parameters. You can’t just spend $50 billion on a reactor and hope it works. That’s why increasingly large and expensive science machines are necessary. Once a design is complete you don’t need diagnostics and scientists. You just need a tritium processing facility, some HTS coils, some vessels, and some plasma heaters.

"This high skills immigration is crucial to American competitiveness, global competitiveness, building these new companies and so forth," he said. "America does not have enough people with those skills."

Translation -- US software engineer salaries are still too high for his liking, so he wants to dilute the market with more to lower the overall cost.
I still use and mostly like FF too, but just look at their marketshare (and their own developer confidence, with Servo and Brave). Chrome destroyed them and I think it was mostly on technical merit, from a general user's perspective.

Honestly Google did everything they could to help FF (to the tune of $400M/year) and Mozilla squandered it. Really sad.

Edit: Before this comment gets downvoted I want to try to explain it. When Brendan Eich wanted to make a new browser, he could've based it on Firefox/Gecko, which he had decades of experience with, but he didn't. What a vote of no confidence. Then Rust was invented because they thought creating a new language was the best way to catch up to Chrome's security. Even if you like Rust, you have to admit that was a bad decision for Mozilla's management.

Mozilla was the good guys, but being the good guys doesn't automatically mean you'll win. Too much wishful thinking can easily cloud one's judgment.

I'm only writing this because I care.
In my experience this really depends on genre. Some sub-genres are absolutely awful in this regard, while others are pretty good. In my experience, reviews on a lot of postmodern books are good as long as you mentally filter out reviews which are basically "I didn't want to read a postmodern book" :).
We could do both. The GND and Freedom Dividend were both aimed at ameliorating major structural impediments to 1) infrastructure investment and renewal, and 2) grassroots-level innovation, respectively.

Of course, since they're apparently anathema to all but the leftiest lefties, we're back at square one trying to figure out what to do.
Isn't it an effect of a feeling caused by governments using experts in a way letting (too often and a too large part of) the public think that they, at worst, are all (gov & experts alike) pushing their own short-termed and only self-beneficial agendas or, at best, nearly always devise some "Grand Plan" which then appears to cost much more than budgeted, gives less than promised and has unwanted unexpected side-effects?

There is a fair part of subjectivity in those opinions, for example most of us tend to forget/neglect granted benefits and focus on unwanted side-effects.

It seems to me that a growing opinion is that governments less and less understand what is going on, and therefore cannot efficiently adequately assess and plan. This is especially true when it comes to managing innovation, which is intrinsically full of new concepts and uncertainty.

Because we don't have stats on what % of home-office owners want to go back to work and there's no way of knowing whether his anecdote is just a token exception, or a representation of a larger outlier. Maybe 1% of home-office owners want to go back to work, maybe 49%. The comment's anecdote doesn't do anything.

More importantly, the comment has nothing but an anecdote that's attempting to make a statement on what the stats will probably be. There's no fact-based discussion possible, only whether you think the anecdote is "representative" or not. Which you have to decide based on your prior beliefs, because the post doesn't contain new information ("X population has nonzero people who disagree on belief Y" is not new information).

I guess I should ask: what discussion could be had around this anecdote, other than "guess the % who agree"?
Eric Schmidt is a household name around here. Doesn’t mean I give a damn about what he thinks.

> Dr Schmidt, who is currently the Chair of the US Department of Defense's innovation board, said he thinks the US is still ahead of China in tech innovation, for now.

“Invest in my next project now, before it’s too late!” is what I read it as.

Edit: let me clarify. Innovation isn't zero-sum. I believe America is the most fascinating experiment – balancing (albeit imperfectly) innovation with ethics. There's a lot of innovation that can happen – and at a cost that's too great.

For example, North Korea has demonstrated an ability to develop nuclear weapons (deep technical advancement), and China can develop datasets on millions (billions?) of people (broad technical advancement). But, the ethical costs are too great. I don't want to celebrate cultures of innovation that do this – foreign or domestic.

Sure, let's always have an eye on increasing our investments against R&D – fundamental and more broadly. But I'm no apologist for falling behind when the truth is that that view of innovation is a zero-sum game where we lose our humanity in the process.

It is ironic that vitamins are okay to recommend. But when practicing physicians got together to recommend HCQ, that advice was labeled as misinformation and promptly removed from everywhere.

Clearly vitamins are better than a drug that has been in use for decades with a proven safety record AND while being recommended by physicians bound to the hippocratic oath.

Why can't there be validity to both vitamins and certain existing drugs? (AND vs OR)

It as though we actively do not want to admit that we may already have something out there that can help us.

PS: Vitamins is a friendly name for often synthetic or derived compounds, not necessarily in the exact same chemical structure as found naturally in organic matter. Not to mention there are also various chemistries that affect absorption etc.
Maybe that's true, but that is not what he is saying:

That's true - and it was always tempting to reach for another expensive sensor when we knew that ultimately we would have to simplify and rely on simpler/cheaper components.
I saw a program in which a geneticist described the gene editing precision prior to CRISPR as about 2-3% and after CRISPR as about 50%. That's a big jump, but as you say, what happens in those other 50% cases is of concern too when it comes to humans. Of course, this precision figure can't also be the single metric on which we judge it. However, it's an indicator that we aren't there yet too .. but are certainly moving in the right direction.

Supposing we can up the precision to, say, 4 9s - i.e. 99.99%, would that suffice? I don't know enough to say anything, but given the number of cells we typically deal with, the chance of a wrong application proliferating, however small, if it gains an advantage over the intended mutation, what consequences would it have?

In order to actually be a fair choice, overpriced means "greater than zero", so I suppose what you say is true, but I object to the characterization of something that you have to actively seek out for no reason other than to view it as advertising, because it dilutes the term.

Older people are not representative of the population, it unreasonable to expect someone born in the 40-50s era to understand the importance of privacy or the social media world of someone growing up today and more importantly shape legislation for future decades - laws are very long living.

It is certainly is possible, but without hetrogenous mixture whether black , women or the young the policies will not be inclusive

Environmental policies, tax, debt , lack of investment in education all favour older people . It is not just because older people vote more. They are lot more likely to know older politician to influence their decision, who is lot more likely to understand and empathize of the problems of his peer group.

The voting bloc influence the baby boomers is well established.

It's a bit off topic, but the seeming "conspiracy" to suppress HCQ has been an eye opener for me. I think the press wants so badly for Trump to be wrong about that, that they're independently all refraining from publishing anything to the contrary. But we heard all about the very flawed or in one case outright fraudulent studies that showed it in a negative light. Meanwhile YouTube has censored videos from doctors talking about the subject. So blatantly partisan and it is costing lives.

I also find it amusing that I get down voted on HN whenever I bring it up. Sheep.
How are we going to ramp up infrastructure projects with zero notice, while people are supposed to be social distancing?
Engineering is more about process and process improvements. If an engineer is breaking new ground they are really acting in a capacity closer to being a physicist.

Consider the famous case of Student's T Distribution - it was discovered via engineering, but it is clearly work that was done in the domain of mathematics rather than engineering.

That which is new is science. That which is re-learning an old lesson is engineering.
That's a lot of euros...

...not to mention they focus on 14 year olds (like they're marketing to parents?). The idea that children should be driving around in vehicles that are the result of millions of man-hours of engineering and thousands of man-hours of labor (adults and likely other children in other countries in the supply chain)... well, that's intensely luxurious. End-of-days luxurious, in my opinion.
Is it really? FAANG jobs are outliers. Some professional fields seem to do OK (medical), but others are atrocious on average (law).

Most people see science/engineering jobs as a path to a cubicle for a while with an OK salary before being laid off at 40. And for the most part, they're right.
That's right; the real-time autopilot is written in C, and the flight simulator is written in C++. We have a really slick configuration system written in Python that compiles down to a Python dict and then a C struct at build time.

Neither Java nor "standards-based browsers" are things the govt has any role or authority to protect. The govt (via anti-trust law) breaks up established monopolies, and very rarely.

I use stb myself, so I have no qualms with that. The point is rather that GP was discussing praise for C’s standard library, and even the most portable single-file include-only dependency remains just that: an external dependency that isn’t part of the C standard library (and no, posix isn’t C).
