Surely airport security was at its peak before the 70s when they started actually screening things? Before that you just got on the plane.

On the topic of subways, I'm always fascinated by the example of Beijing's line 2. It was planned as a circular route approximately following the old city wall. They couldn't afford to bore the tunnel, and had to use cut-and-cover instead. This consists of digging a trench to the desired depth, then covering the top. Of course, this requires destroying whatever is on the surface there. This would have destroyed a lot of people's homes. But a solution was found: rather than approximately following the old city wall, how about exactly following the old city wall, and destroying that instead of people's houses? Nobody lives in it, after all. And thus Beijing's line 2 was born, and the centuries-old historic city wall is no more, aside from a few preserved gatehouses.

Imagine trying something like that in a place like New York City.
I guess this "conventional" thinking was due to the fact that electric car startups had bad history of not delivering.

Tesla excites investors because they have history of not only delivering but also exceeding expectations. I think as long as they keep delivering on those expectations, they will be immune to conventional valuation methods.

No actually very few of my reasons for pointing out his lack of integrity have to do with simple disagreement on policy. I would try not to label people as narrow minded based on one short comment on the Internet. This community normally does a better job of not immediately devolving into personal attacks especially when you didn’t even ask what my reasons for disliking him are.

Read a much more in depth analysis in one of my other comments of his transformation of the FCC into a partisan agency, his attacks on poor people through the Lifeline program, as well as his close ties to Verizon which create a direct conflict of interest: https://news.ycombinator.com/item?id=15781535

Not to even mention the post that started this thread about how Pai has accepted over a million fake comments on net neutrality from the telecom/ISP industries’ astroturfer lobbyists while refusing to provide enough information for NY to look into the matter (or investigating themselves)

There are people playing devil’s advocate for Pai’s views but how many people actually seem to strongly want these changes? Have you met any who don’t work for Comcast, Verizon, etc.? I honestly have not

My understanding is Tesla is development process company focused on learning and iterating with the production being only by-product of that process, necessary to keep the promise of greateness alive and also to support the learning process.

My experience, it is neigh impossible to really learn without delivering the product, but you can learn without bringing in profit.

Nearly 80 interviews with Americans targeted by Fancy Bear, a Russian government-aligned cyberespionage group, turned up only two cases in which the FBI had provided a heads-up.

If you were targeted by Russian hackers, and you happened to be a high level government official, would YOU admit to it? This is like asking a room full of thieves if they robbed the bank. I think it's more likely the FBI DID notify many of them that they had been targeted, but like the DNC, it either got lost through the cracks, was ignored, or possibly seen as some political ploy.
tl;dr: The Intel Puma 6 and Puma 7 chipsets have a performance issue in a part of the packet processing that is specific to TCP/IP, which went undetected for awhile because "ping" packets are not TCP/IP. Modems that use the affected chipset will have high jitter under load (especially load consisting of many short connections), and will suffer denial of service when sent traffic with many different port numbers. Additionally, under a previous firmware (but according to a commenter on https://www.reddit.com/r/news/comments/7fjvvt/hundreds_of_mi... not on the most recent firmware), a timed process would briefly block throughput every 2 seconds, adding to jitter issues. DSLReports has created a tool which checks for this at http://www.dslreports.com/tools/puma6 .

> I wouldn't trade Linux for Windows for any sort of development work.

Same. Windows has all the Linux dev tools plus a huge host of tools that Linux devs can only dream of. The only thing I need/want Linux for is cloud deployment. If I'm deploying an Intranet server, Windows servers is what people want there.

It amazes me that Linux devs speak so highly of their own tools and yet they can't even build a decent desktop system that just works, that masses of people want to actually use. And devs are people too :)

Many times I've read a game review by someone who has no interest or experience in the genre. While a different point of view is always interesting, I personally enjoy reviews and writing by someone at least knowledgeable about the subject matter and its context.

An example was a review for the Crash Bandicoot remakes by someone who has never played or been into classic platformers. Therefore, the review was mostly complaining about how you go back to the beginning if you lose all your lives (!?).

Personally, like others have said, I rely on friends and communities devoted to a few specific genres I like (turn based JRPGs make up 80% of my game library).
Facebook didn't create that world -- it has always existed. Facebook only exposed some previously underrated features of the human society. It's very naive to expect that it can fix it. A social network (or any other technology) can't fix humans just like telephone or television couldn't. Like any massive technology shift it requires new social education. For instance, be very mindful about what you post and who can read/see it, beware of social bubbles and bots, employ critical thinking. The process of education will take time but eventually new online social norms will be formed and the early adopter problems will fade away.
These are very pretty books, and at the same time very ugly. Thank god I already know the material in these books, I wouldn't want to learn it this way.
I'm talking about a different space.

A closed loop farming ecosystem where plants filter water and fish fertilize plants. There's a lot piping and artificial structure to facilitate this type of environment but the control system is largely self regulating, there is less need for a computer to intervene, although it wouldn't hurt.

See:
http://homeaquaponicssystem.com/basics/hydroponics-vs-aquapo...

In my research, aquaponics is the most nutrient dense farming system available. My eventual goal is to produce a farming system that can live on a single typical suburban property, function with minimal care and produce enough yield to feed a single family. That's right, Fish and veggies on my plate from my farm, daily.

The openAg platform seems great, however to make it fit with aquaponics it would need pH control system and a separate tank for fish.
> there is a whole invisible world (or spiritual dimension) which has nothing to do with our material experience

More likely most of us don't understand the connection between the material world and these dimensions, and whether they truly are separate or not.
I was thinking a lot in terms of device support too, I guess. That's important to me; I know with C that I don't have to think too hard about which device, at least in terms of "Does this board support my language well".

It's probably even more important for professional embedded engineers, where the hardware decisions may not even be made by the software developers, for various reasons.

This is just standard custom in the Northeast - lanes don't end, they merge. Keep moving while zippering, and the unfairness will be limited to a maximum of one car (someone who really wants to push it).

The downside is that the same philosophy is applied to eg exit only lanes. You'll get a 3-lane highway with a backed up simple exit, and only the leftmost lane is passable (with speed hindered by a constant worry that a stopped car will try to change lanes into you).
Neither people nor AI are generally smart.

Tesla going bankrupt wouldn’t be an isolated event. It would probably be something like the aol-time Warner merger or the Lehman Brothers bankruptcy and trigger a general market correction.
That space just becomes empty, and can't be reclaimed. Thus useless.

> Tesla is not a production company yet. Tesla is a promise of what it can be.

A company that loses $1.5 Billion per quarter? Not even Amazon at "peak investment" had such horrible cash flow numbers.

There's very little value in a charity. If Tesla can't correct itself and actually start making money (or at very least: become a sustainable charity and prevent itself from losing money!!), then it simply has no future. It will eventually run out of cash and die.

That's the worry. If Tesla dies, then Tesla cars won't have anyone to take care of them, because Tesla's horrible model prevents 3rd parties from learning how to maintain a Tesla car.

Also, bankruptcy is not a "hack", it is a legal process to protect creditors / vendors / employees as well as companies. while there is a widespread belief, encouraged by politicians post financial crisis, that companies use bankruptcy as a way to protect themselves from risk, that is incorrect. Bankruptcy is a legal process for dividing up a failed companies assets so that it is not a free for all. It protects employees by preventing powerful creditors from forcefully claiming value until other constituents get paid in accordance with the legal statues of the process
This view may seem like stupidity, but it's bought and paid for. Just as it may seem like stupidity for the FCC not to exclude the comments that were done by bots, it's not. It supports their opinion, so they keep them.
Please don’t run around seeing conspiracies when a more likely explanation is that there are non-trivial numbers of people who hold opinions different from what you expect.
I share your opinion, if you have any bottlenecks which are unsolvable because of Rails or Ruby being slow your app probably scaled up to a point where you have the resources to make a creative solution that is not Phoenix/Elixir.

Having said that, while I don't find any major reasons to opt for Phoenix instead of Rails, my main reason to work with Elixir/Phoenix right now on side projects is that it won't make me unlearn Rails which I can always go back to, in fact, using Phoenix for a while made me miss a lot of the available libraries, plug-in solutions and wide range of community knowledge.

So ATM I have more reasons to choose Rails over Phoenix, but I suppose that's why these sorts of articles are important, publicity to increase a community and fulfill Elixir's biggest need right now.
As a taxpayer, I support Tesla, am glad to have subsidized them, and I don’t care if they turn a profit.
> Logos should be simple.

Agreed. Simple but important things to also consider with Logos include "What does it look like if printed in black and white?" It's a bit outdated advice in some regards, based as much on letter headers, fax machines, and news print adverts, as anything else. You'll notice that almost all memorable logos work really well in black and white, though.
One substantial possible factor in Tesla's bankruptcy is competition. You suddenly now deal with car manufacturers which are woken up to the electric drive age.

Thought exercise: how can competition take serious levels while Tesla produces half or more of the world's battery capacity?
That's not how proration works.

53¢ is the US government's ("We're here to help you!") estimate of the total cost of an average vehicle divided by the lifetime of the vehicle as measured in miles.

If your vehicle's lifetime is 200,000 miles, and 10% of that is assignable to Uber, that is 20,000 miles or $10,600, which is 10% of the estimated lifetime cost of $106,000.

If you try to break that up into different "buckets" ("I need a car anyway, so I shouldn't apply the fixed costs to my Uber income"), you end up with a car that effectively only lasts 180,000 miles and therefore your fixed costs for the car for personal use are artificially higher. It is the same thing as if you had decided "I would just burn that gas anyway" and didn't count fuel costs against your Uber income.
Devs need to remember to use performance monitoring tools to see where the slow code is - we had an app that could come to a halt if more than 10 people logged in, in one second - it took forever to dynamically generate the menus. Stupid recursion error, quieted NewRelic alerts down right away.

No doubt that elixir / erlang are an extremely useful and brilliant technologies but the article is simply bollocks measuring apples and oranges.
The database doesn't need to be an issue - it just currently is. We have a fairly complex query on a several terabyte large PostgreSQL database and didn't want to spend more money. Basically, we just haven't sharded it yet, and don't want to pay for a larger machine. The point is - typically the issue isn't the web app. Almost all web frameworks are designed to be scalable from the start. Just launch another instance.

Also, we do about 99 writes for every 1 read, so query times don't matter as much. For the given app I was using as an example.

Network I/O and large databases are usually the bottlenecks from what I've seen consulting and developing.

Well, recently I find myself approaching every problem of psychology with the starting point: "The human brain is a neural network, therefore..."

I'd like to somehow develop some new techniques based on this (as opposed to all the prevalent ones you find in self-help books). Right now I can't afford the time, but I should be able to make some headway next year. fingers crossed
Anybody listened to one recent conf call with Musk ? it was on youtube.

He seems to be in some good sht (subpar assembly line for the batteries and/or engine having to be reassembled from scratch which is done according to him) so so far this particular problem is not out of control for Tesla, but then time is critical too, competition is ramping up, and laws are shifting (EV tax cut is gone now I believe).

I like Musk approach of going legacy free to stretch the limits of the current model, as he did for SpaceX. I'd be sad if Tesla choked enough to crash. If he just made it to the model 3 production that would be "cool".

I don't know how people in the know understand the recent Semi/Roadster unveiling, is it distraction to get some buzz or a final scheme to finance the model3 step with easier things to be done in 2020 (smaller market for Semi and I believe a litle less complex to build than a cramped 4 seater)
Which even amplifies the observation. Not only is the process of proving a theorem more complex than it looks in retrospect, but the whole process of deciding whether a theorem or even a whole field of math is even useful or not can be driven by chance over a time span of decades. What is now "topology" was kicked around for many years with many approaches before a general agreement that open sets formed the most useful basis (heh). Advanced textbook authors regularly have to cut topics from subsequent editions of the book, because what seemed promising 30 years ago turned into a dead end. So math is far from the discrete list of topics and answers that it seems to be when you're picking out classes in your syllabus.
For a bit of insight, Python is the 'glue' that delivers information between Gtk (the frontend) and PostgreSQL (the backend). Python also creates the Libreoffice documents using the py3o libary. Python is an important part, but not the whole picture.

Are you looking to collaborate for the sake of Python alone, or is the accounting system of interest to you?
Yeah, ultimately the Concorde failed because it was worst-in-class for the stuff that turned out to actually matter (cost per revenue passenger km, noise, range)

The "spruce goose" still holds the record for biggest wingspan of any aircraft and largest ever flying boat, and the Hindenberg class airships for largest ever aircraft (and probably least flight-like experience), and ultimately Concorde's speed turned out to be no more relevant to its commercial viability...
I know this comment might attract a lot of hate, but I will put it here anyway.

The main reason why Facebook is not in China is that Chinese government wishes to regulate Facebook while Facebook (like Google) refuses to obey.

In some ways, Chinese government was right in the judgement that unfiltered and unregulated freedom of speech bring its own problems. And now the Western free world is starting to see these problems and impose regulations.

Love this article. Very interesting, and I love how the results are able to be quantified.

Coming from some projects that had a very heavy unit testing culture, I can agree that unit testing doesn't always necessarily have the intended results on "quality" and can really shape a codebase.

I feel the root of the reason is that testing is not the same thing as development. Truly testing things involves a mentality that is different, it involves understanding how mulitple pieces fit together and operate in reality, not in some unit testing framework. A lot of developers look at unit tests the same way they look at development, once they work, it's done. But testing is proving they work in all the right conditions, not just getting it to work once.

I've personally seen very simple code convoluted so that it could be unit tested, and how those convolutions can easily add bugs and additional layers of indirection that hurt performance (as well as add unnecessary code, which needs maintenance). Many times these tests could have been written with the existing code as long as it used some other component... but then it wouldn't be "unit testing" only to see these components not work together on the first runtime. (For some reason, places that rely heavily on unit testing seem to have fewer overall or integration tests, because they spend so much time and effort on unit testing)

I'd love to see a study on how many lines of code change because of unit tests vs in non unit tested codebases. Both in terms of how many unit tests need to change and the size of the change itself.
For reference, what I have used that makes me claim this without being misleading (not necessarily all at the same time):

https://rocket.rs/, https://rusoto.github.io/rusoto/rusoto_core/index.html, https://docs.rs/postgres/0.15.1/postgres/, https://docs.rs/kafka/0.7.0/kafka/, https://docs.rs/reqwest/0.8.1/reqwest/, as well as many other supporting libraries. I've not run into many things where there isn't already support.

Also, in terms of networking, if your doing blocking IO, the stdlib is fine. Otherwise, from my experience, I really like https://tokio.rs/ for non-blocking (I know people are torn on this one) and have used it in my DNS impl, https://github.com/bluejekyll/trust-dns

Correct. But private corporations can choose whether or not to follow in the path of liberal democracy or authoritarianism in how they relate to their customers.
