> They still can't build proper software. Academics (including mathematicians) are notoriously bad at writhing production grade software. This leads to handovers of 'proof of concepts' to seasoned software developer team who than struggle with the (often complex) mathematics/science behind it.

So you want employees who can understand complex mathematics and science but are also good software engineers.

Those people exist, but you have to pay to get them.

(As an aside, lots of Ph.D.'s -- especially in CS -- build systems that are as good or better than a lot of industry code. All of the best and worst code I've read has come from Academia.)

>Pediatrics is a journal published by the American Medical Association. In general, I hold the belief that it publishes material in furtherance of medical science and public health policies which are intended to produce positive medical outcomes subject to normal variation in human ethics and fallibility.

Well, popular (or increasingly mainstream) results get more grants, peer acceptance and media coverage, so there's always that.

Up to the eighties those same journals would have no qualms "proving" that homosexuality is harmful, and in fact there were tons of studies to that effect.

(It works the same, but with an inverse sign, for those scientists going for the conservative audience and its, increasingly fewer, and more marginalised, grants).

So it could be more that the tide has turned, and a push to get a cute result to publish and get some publicity and good will, than an actual causation.
This is good advice I think, being as programming wasn't really a passion of mine; just something I got into when I had to grow up quick, and it worked out well.

Once I started and got past the imposter part of it all I went to startups, where they drained all my energy from myself and my family, just as you suggest.

Now I'm somewhere that requires very little of me technically, where I can work pretty much JUST 40 hours and get by and make everyone happy.

I still struggle with trying to make more out of it than I really need to.

I still struggle with wanting to do something totally different, way outside of computers. I feel like I've "conquered" this already. (I know, that's really shallow).
Thanks for the feedback, I really appreciate the time you took to write this! Btw. being fairly new to sites like Hacker News and Reddit, I'm actually amazed by how nice this community is.

You are right, the write-up isn't meant for newbies to the topic. I'll definitely think about updating the intro to reflect that.

Regarding the ML series: aren't there already quite a few introductory series into the topic, which can be referred to? Because the text I wrote on the project page wasn't intended to be a guide of how to build a project like this, but rather to give a glimpse of how such an algorithm might work. But anyway I must say that I really like your concept of an interactive tutorial series. Maybe I'll write a guide to a project like this in the future; would also contribute if someone else does (to anyone out there).
Merging our brains with machines won’t stop the rise of the robots
Firstly you have a mess you need to clear up, have you bought out your other co-founders to ensure you own 100% of the company ? - you'll struggle to find investors if you've got zombie cofounders who may claim to the company, you need to get the paperwork sorted out now.

Next understand why investors want you to have cofounders.

It's not some arbitrary standard, you simply won't have the cash to be able to hire a top tier sales, marketing person, etc. so bringing that talent onboard as cofounders is how you should be solving that problem. Find the best people you possibly can who cover the areas that you're weakest in. Find people who've experienced growing a similar company, they'll be invaluable to you.
The track side equipment is really expensive and there is little competition in the rail-space. Everything is regulated to death and only huge companies have a chance. So you have maybe two or three companies who can bid.

Strange, I don't even known anyone who likes Billy. My wife and all her late 20s age friends all prefer kallax:

If you want to use it as a bookshelf, it works fine. If you want to buy the little cloth cube drawers it works good as a dresser or for storage. If you want a bed side stand you get 2 cubes tall, if you want a shelf you get 4.

Billy just seems kind of weird and irregular with the varying widths. I wouldn't want one either.
Being able to ship something is definitely important as there are a lot of junior (and even more experienced devs) that just can't seem to finish a project.

Also, stick around for a while after it's been shipped or deployed and see what kind of difficulties the ops guys have with it if it's a SaaS product or the customer support team has if it's a locally-installed product. There is a huge difference between shipping a working product that is simple to operate and support vs. one that requires constant care from an expensive ops or support team.
Those ONS numbers you cited would account for 2.92 million EU citizens living in the UK (3.2m * 0.83 + 5.4m * 0.05), but there's also the possibility of UK-born EU citizens living in the UK. Which admittedly doesn't exact fit most people's definitions of immigrants but may well be included in the Independent's number.

It's also not clear how how the ONS numbers account for dual citizenship, since their numbers all up exactly to 100%.
You tell people you have a lot of money?
You can apply Occam's Razor here. Which is more likely?

That there's stuff that has a mass but doesn't interact well with light, or that space is able to curve itself without mass, thus also rendering Einstein false.

This immediately raises further questions: How long does space remember? How's the exact mechanism? Where and how does empty space store that information? What happens to E=mc2?
Exactly. This is one place where the "good school" heuristic is actually a good one -- those programs almost uniformly demand some mathematical maturity of their students.

I've known many CS undergrads who are better mathematicians than people with graduate Mathematics training.
So, you would say smart watches are "ready"? Despite the abominable battery life the Apple Watch gets, even though it isn't Always On? Would you say the Internet Of Shit is ready?

In the same vein, the low-resolution, headache and nausea inspiring VR headsets of modern day aren't really ready, even though engineers are making the best of what they have.

> I struggle to see where you would prefer Qt for frontend code if you don't need a native app.

How about actual native UIs instead of ugly, non-intuitive, slow and massive Electron apps?

I say this being a dev who works with both Qt and Electron on a daily basis. Electron has its place - but its place isn't good desktop and mobile apps. Qt is much better suited there.

Electron is only well suited if your team is extremely familiar with web dev but nothing else and you have no ability to hire a good desktop team or you need to interact with a web-only frontend library.

Just about everything in Qt is preferable - native look and feel, proper layouts, high performance rendering, small distribution size. I struggle to think of any way in which Electron is better except for perhaps library support these days.
The author seems to ignore that GCC's implementation of std::hash is the identity on integral types:
https://github.com/gcc-mirror/gcc/blob/cf8c140a8b8131b3ab4f5...

This is an incredibly poor design choice (at Facebook we'd say "clowntown") as it makes it unusable with any sophisticated hashtable data structure that assumes reasonable randomness. That's what causes the quadratic growth in the sequential example with dense_hash_map.

The solution is to use better hash functions, not prime hash table sizes. Prime modulus will only make the problems harder to notice, but if you have a poor hash function, you're giving up every complexity guarantee. Note that even if you reduce modulo a prime > n, you'll still have the identity over the first n numbers.

Personally I just use folly::Hash (https://github.com/facebook/folly/blob/da08e63ce3bac9196b18d...) as it uses sane defaults for hash functions, and contrary to std::hash it's a polymorphic functor so you can just drop it as template argument without having to specify the key type: dense_hash_map<int, int, folly::Hash>.

The other reason dense_hash_map uses power-of-2 sizes (other than to avoid the modulo) is that it is sufficient to guarantee that the quadratic probing schedule is transitive, that is, it can reach all the slots of the table. Quadratic probing is used because it's very effective for unsuccessful lookups. You can find a table of expected probe counts at different load factors here:
https://github.com/sparsehash/sparsehash/blob/4cb924025b8c62...

Hash tables are a fine craft. While it's interesting to gain these experiences first-hand, this is an amateurish post and it should be taken with a grain of salt.
> I'm a big fan of rail. I wish we had a bullet train going from E to W coast through Kansas City. I would happily pay more taxes for it.

You're in the "people who like rail" camp. So are many of my friends. (I'm the lonely S.O.B. in both.)

> Why is [our cost] so high per mile?

On why rail is so much more expensive here, we don't know [1]. "Many of the world's most expensive projects are in the United Kingdom, Australia, and New Zealand, which, like the United States, have common-law systems," [2] so it might be that right-of-way costs dominate.

New York's MTA costs $4.11 per ride to operate [3]. The analogs for London and Paris are $2.61 and $1.93, respectively [2]. The cost difference appears to be explained by unnecessarily higher staffing levels in New York. So it might be that public-sector union and well-paid contractor costs dominate.

Measuring these things is hard, perhaps intentionally so.

Against Legislating the Nonobvious
But there was immigration without control for so long, with it's negative (and many positive) drawbacks. There should be a limit on that. Also, in big cities there are irreversible cultural changes which I consider harmful. Huge mosques, no-go zones, etc. I don't want my children to grow up in something like that.

Therefore, my presence is only temporary.
Usually it comes in the form of telling blue-collar people that any threat to their business model is a threat to their jobs. It seems to be very effective.

We've seen instances already where gravitational lensing was explained through other means (very dim clusters, dust, and even camera issues), we also don't know if the space time on those scales is "smooth", if it isn't then light will not travel in a straight line which would account for the lensing effects.

The spacetime curvature, mass/energy, and gravity have quite a few interesting interactions as in gravity as a force, vs gravity as a feature of spacetime, vs potential other forms of gravity.
We aren't even sure at this point if a curved spacetime without mass/energy that would generate that curve, would actually produce gravity or not since we aren't able to observe this nor do we have a complete theory of gravity.
It would probably perform pretty poorly as other has suggested. This is mainly due to the fact that stock prices by itself is a pretty non-stationary dataset/measurement. Most of these probabilistic models are poorly equipped to make accurate predictions for non-stationary data since it's trends are seemingly similar to noise.

It pays so well because everyone needs a technologist, in every industry, in every department, in every building. It's "in".

Now, if it's truly unpleasant - there's a major problem there. Usually somewhere else, another way, perhaps another industry (same line of work) can solve that problem.
I get the whole "cautionary tale" thing, but you should probably contact Apple to remedy both your personal loss and so that they have more information about failing components. In my experience they take this stuff very seriously.

This might sound like a troll, but the bubble effect on HN really is that strong. The community sometimes has a strong tunnel vision and doesn't realize how it's constrained by what's on the HN front page.
I agree. I work in the UK, and used to go to SFO twice a year. I am now telling my manager that I am not willing to take the risk to be arbitrarily detained for no reason, even if it's only a 1% chance (which sounds about the current level). Send me to any country, but only where the rule of law applies.
Nope, definitely wasn't right in most cases. I can understand why some of it exists, though - like not being able to be forced to testify against your spouse. The two people who are married are supposed to be "one" so the extension of the fifth amendment makes sense.

But a lot of the other stuff having to do with tax benefits...I'm not too crazy about. The government is notorious for doling out tax benefits to activities they want to promote. Like the mortgage interest deduction. The government wants to promote home ownership so they created that to incentivize people buy homes. That's arguably the most popular tax break out there, but all it does is give preference to how you spend your money. Spend it on something the government approves of, and you get a tax break. Similar story with child tax credits, dependent care credits, etc. They are basically rubber stamping certain life choices. And the effect is that people who neglect or outright refuse to engage in these choices/expenditures end up paying more in taxes, all else being equal.
"Why isn't Google requiring CAPTCHA on the notices? They ARE supposed to be filed by humans after all, no?"

This is true. We humans have to deal with the Google captcha stuff all the time, and so should DMCA report filers. It's only fair. There shouldn't be any sort of automated submission process, because clearly it's being abused constantly.
Of course, it was a Hollywood funded "law" anyway, so no surprise.

>With this approach, your novel becomes an average of what the masses like to read, rather than what you wanted to say. Engineered for the masses, so to speak. Which, of course, could explain why King is so successful.

If your goal is to make a lot of money selling, then "Of course!"

However, I submit to you that King is not a massive success because he targets the average. He is a success because he writes well. His plots and stories are not that great - even his fans agree. But his ability to suck you into a story is quite strong. As he said in his book:

"The job of a storyteller is to get out of the way!"

This means no fancy literary devices that let the reader appreciate the choice of words - that alerts the reader to your presence, and distracts from the story. It also means strong settings and descriptions.

The Galant desks are not sturdy. I would not dare to stand on one. First of all, if you use the telescoping legs, the locking mechanism is plastic IIRC and can't take a lot of load. But even just the actual desk surface: I think it's a sandwich of paper honeycomb with a very thin veneer and bends a lot even when someone's just sitting on it. It would probably just break in half if you stood on it.

It is light so that's a plus.
I'd say the author's voice shines through even clearer in fiction though. Authors certainly can exercise flair when writing history or something, but even more when they invent a fictional world and develop and atmosphere and characters within it.

When a fiction writer comes up with a plot, or even a turn of phrase that blows my mind, that's one of the best things about reading. Like "how did he think up all this?!"

I am very skeptical about recycling (I do recycle though) - it seems like a tremendous about of CO2 is spent just moving the recycled goods from homes to the recycling facilities + the energy spent recycling the product + the energy used shipping the product to a plastics distributor. The option of filling our landfills is also costly but is it offset by recycling?

Does anyone know how recycled plastics stack up against new plastic once you consider the energy used in the entire recycling chain?

If it was just galactic rotation curves that would be explained by adding a (mostly) non-interacting dark matter particle, then MOND would probably have many more proponents. It's harder to understand how to replace non-interacting particles in explaining the cosmic-microwave-background power spectrum, galaxy clusters, and structure formation. Maybe it's possible to make a complicated theory do those things, but at that point, I'm not sure it wins on simplicity anymore.
> I struggle to see where you would prefer Qt for frontend code if you don't need a native app.

Specially on mobile. their decision to go with QML for mobile OS support, requiring devs to replicate native widgets, means it is a bigger effort to create multiple QML frontends, than it is to follow a MVVM architecture with as much code as possible in C++, while using native support directly, even if in different languages.

Also for those targeting mobile OSes, Xamarin has a much support for the respective OS APIs than Qt, that usually requires the extra effort of manually wrapping many of them.

As someone that prefers working on native apps to web ones, I kind don't understand their current roadmap, it appears that they are trying to spread between C++ and JavaScript devs in an attempt not to lose mind share.
This is a nice piece of work - thanks for sharing with the community!

Some feedback: it'd be nice to see you actually quantify how accurate Prophet's forecasts are on the landing page for the project. In the Wikipedia page view example, you go as far as showing a Prophet forecast, but it'd be nice to have you take it one step further and quantify its performance. Maybe withhold some of the data you use to fit the model and see how it performs on that out of sample data. It's nice that you show qualitatively that it captures seasonality, but you make bold claims about its accuracy and the data to back those claims up is conspicuously absent. Related, it might be worth benchmarking its performance against existing automated forecasting tools.

I'll definitely be checking it out!
It's a ton of stuff rolled in to one.

First, regular railbed isn't nearly as hard to build because the standards are much lower. When you're building for 70mph max freight you have a totally different need than 186mph+ HSR.

For example, HSR uses a high alignment specification. This means a great deal of effort goes into ensuring that there are as few variations in the alignment as possible to ensure it is stable.

You also have cost of catenary (overhead wires), cost of bridges, tunnels and grading for a much straighter tangent and finally all the electrical and signaling infrastructure behind it.

(Note that the signals are in-cab signals but modern systems such as those from GE/Alstom or Siemens still require lineside equipment.
It is almost like there is a secondary agenda here. It's difficult to see how anyone arrived at these conclusions.
