While I'm not one to subscribe to conspiracy theories, I've always thought that bicycle helmet laws and related press were pushed by helmet manufacturers.
Actually, that's an excellent point -- how do buildings/bridges/etc. actually get built? I mean, laugh if you will, but can you not think of any examples of construction projects that straight up ran out of money and had to halt? Or that became enormous money and time sinks, inching their way but never-quite-making it to completion?

As I understand it (still pretty new to the industry), we're supposed to give realistic estimates for a product's completion, considering that 1. requirements are always incomplete and 2. unexpected complications will always arise. 'Done' is a moving target, and part of its estimation is ensuring the product is deliverable at every stage (with varying degrees of completeness), regardless of whether how many times everything goes pear shaped.
There are plenty of studies, the problem with them is that there are arguments made constantly that despite the efficacy of helmets in reducing the severity of head trauma, something about the helmets somehow makes them more dangerous.

I think my favorite stupid argument though is that it increases the size of the rider's head, which increases the likelihood of ground collision in an accident. As though it's so easy to stop yourself from falling as long as there aren't two inches of material strapped on your noggin.

The basic fact is that if you do have a head injury on a bike, a helmet is likely to reduce the severity of it. Everything else is an unquantifiable argument about human behavior.
Most startups begin life in total obscurity and only transcend that nameless wasteland through sheer cheerleading force. I get that it can feel a little rah-rah, but as a founder that function is firmly on your list of jobs.

It would be strange to read a founder-penned startup missive that didn't toot a few horns.
I'd add "Mandatory and significant jail time for leaving the scene of an accident". A local lawyer just got off with a 30 day sentence after he hit a cyclist and drove off because he claimed he thought he hit a deer or rock. And this was after he admitted that he just came back from a function where he was drinking. The prosecutor was looking for a felony hit-and-run, the judge reduced it to a misdemeanor because "This could have happened to anyone." So, the moral of the story is -- if you hit someone while drunk, don't stop, just drive home and sober up, then claim you thought you hit a deer.

People fall and hit their heads and die walking and running all the time. Why not make pedestrians wear helmets?

Or how about you stop using the law (violence) to protect people from themselves.

EDIT: Laws like this are also a great excuse for police to harass people. We don't need more of these.
So your point is that Amsterdam is already more safe to ride a bike in, so wearing a helmet doesn't add safety anymore, whereas in Seattle it does? I mean if this is really what you're claiming, then I hope I don't have to spell out the flaws in that argument.
Ever been to NZ?
I rather think you miss my point. For every company at your stage who thinks it might be a bad round, ten are dying to get in - there are few to no ways to make as large and fast connections. I suppose it depends on company's long-term plans.
Aside from starting with some nirvana fallacy at the beginning, the conclusion is basically an accidental advertisement for XP.
I think you need to better explain what you do.

I looked through the site and saw modules I could add . . to something.

I clicked on one module to read more about it and there was a one-line description and an image slider whose thumnails wouldn't expand.

I like the sound of "DIY" (probably not "DYI" as in your title), I like the sound of "Microservices" and "Serverless AWS", which sound like buzzwords I'd like to learn more about, but the site doesn't answer those questions, even for someone curious enough to poke around.

The template placeholders like "User review User review User review" don't inspire the kind of confidence people will need before they "Add to cart" for $14.99 to somehow deal with credit cards.

I realize this is "Show HN" and you're not launching. I don't mean to sound harsh.

I do think you need to polish things more, and know that HN readers are your actual audience.

One nitpick - clicking on the "Recommended Microservices" section leaves you in the same position but should scroll to the top of the page.

Nitpick 2: I tried to enter my email to be notified of updates and the form doesn't work.
The fact is that HUMANS will build the new reactors; interfere with engineering plans and systems; and not be trained properly.

If a reactor can't be safely designed, built and run by fallible humans then it shouldn't be built.

I have talked to people in the coal power industry. There are plenty of cases of accidents.

In one case they started up the generator with the oil pumps turned off - the multi-tonne rotor ripped off the bearing then rolled through the hall crushing everything in its path. What if that had been a nuclear power station?

A manager without a clue asked for a chute to be opened, the worker tried to explain why that was a bad idea, the manager insisted and a few kilograms of coal dropped down on them.

It can take minutes for the mulit-tonne generator to synchronise with the 50Hz supply frequency. There are special electric motors that retard or advance the generator until it is in sync, then keep it in sync. Normally there are resistors to allow the sync to happen slowly. However in one case it was thrown to full power before the sync was complete. There was a momentary blackout through the southern UK while a huge amount of power was used to sync the generator in a fraction of a second. Strangely the fuses didn't blow.
One of the more compelling use-cases for USB over IP is connecting proprietary licensing dongles to virtual machines.
This reminds me of reading _why's stuff back in the day. Bravo.
Yes, it is similar approach to JAWS, with an abstraction layer that could scale the framework and ecosystem across cloud providers. We have presented this last week at AWS re:Invent 2015 - https://www.portal.reinvent.awsevents.com/connect/sessionDet.... The feedback was overwhelmingly positive, so we'll continue iterating to empower developers build and publish their microservices applications to the marketplace; and on the other hand to enable enterprise customers to consume and package the microservices into web apps that will be deployed into their accounts from cloud providers like AWS.
Do you believe we would be better off if we destroyed/prohibited all the technological innovations you mentioned in your comment? Stop for a moment and think about that. Then, read the article below:

Hi, I would discuss the impressive contrast between these thoughts and the facts of reality with you, please; thanks! :)

Coal has been replaced by a combination of natural gas and renewables in every state. As more renewables come online, natural gas plants will run even less.

I'm tired of humanity throwing money down the well that is the nuclear power industry. Pay for the damn turbines and panels already and be done with it (the US alone has enough wind energy potential for 10x its current energy use).

Note: Wind is already so cheap, Exelon's CEO (who manages the largest commercial fleet of nuclear generators in the US) is threatening plant closings if they don't get a bailout.

http://articles.chicagotribune.com/2013-02-08/business/ct-bi...

The former Exelon CEO? Says that shutting down struggling nuclear power plants is the right thing to do.

http://www.eenews.net/stories/1060022403

Do I care that natural gas is going to pick up the slack? Of course not. The natural gas boom won't last forever, prices will rise, and with coal no longer meeting EPA emissions requirements and nuclear plants decommissioned, there will only be one power source to pick up the slack: renewables.
A counter-plea from someone in Software Support to never implement something as haphazard as SMS-based support: We have more than enough trouble already getting people to tell us exactly what their problem is when they have the expectation that they must send us a communication with a clear subject and body (not that this stops the random e-mails with no body and a subject of "HELP!"; or the e-mail that evidently went through five people in their company before going to us and contains "FW: FW: FW: FW: App Crash" in the subject line). Do you really think the kind of support we can provide will improve if the expectation is that the user is going to provide as little information as possible? Here's how I expect such an exchange would look:

User [1:51 PM]: help plz

CSR (Customer Support Representative) [1:51 PM]: Hi there! Thank-you for contacting support. What can I do for you?

User [2:40]: whats a platform

CSR [2:42 PM]: How are you running this app? On your PC? On a tablet? On your iPhone?

User [2:45 PM]: tablet

CSR [2:46 PM]: I see! And would this be an Android tablet or an iPad?

User [2:50 PM]: at&t tablet

CSR [2:52]: So you got the tablet from AT&T. Do you happen to know what operating system the tablet runs?

User [3:00 PM]: no i dont f_cking kno what os it runs. i already said i got it from at&t. your sh_tty app is broken and its been a goddman hour and u still haev no idea (1/2)

I worked on an estimation tool[1] inspired by PERT 3-point estimates for a while, simply because there weren't any when I went looking one time.

It was a lot of fun reading up on the estimation literature in various disciplines. Personally I think that the real magic of PERT 3-point estimation is the "unpacking effect" -- making people think about the subtasks of a headline issue.

When I'm in situations where I point a story, I like to ensure that we engineers say aloud what assumptions we're pointing on ("Bootstrap will make responsive mobile almost free") and then a quick low-detail breakdown of expected tasks ("new page, new RESTful endpoint, new model code").

I find that the latter, in particular, makes a big difference in how pointing goes.

That assertion is incorrect. There were other Nuclear Power Plants that were closer to the Tōhoku earthquake epicentre and just as affected by the proceeding tsunami. Of note is the Onagawa NPP which was used as a refuge to house residents (in the site gymnasium) during the event. [https://en.wikipedia.org/wiki/Onagawa_Nuclear_Power_Plant#20...]

To say that the plants construction in an earthquake prone environment, solely, would inevitably lead to the incident is false. Just like with most incidents (e.g aircraft) it is a compound of faults but most importantly obtuse human error and/or mishandling.

I've got a couple of the Chinese made "Remote USB" servers which are interesting but not as compatible as I would like.

What I find really amusing is that back when USB was proposed I argued that rather than create an entirely new infrastructure why not just use Ethernet packets. There are additional protocol types available in the bit encoding and all sorts of infrastructure that already supported layer 2 switching. Plus the "phy" (10/100 at the time) was dirt cheap and already available. It never went anywhere, and at the time I figured that nobody wants to support a standard that they can't see how to make licensing money off of it. Somewhere I have VHDL code for a PC parallel port emulator that ran over my protocol. It fit in a small FPGA with the ethernet MAC so it wasn't like we were talking about a lot of gates. Just no consortium fees and no way to keep people out of the ecosystem you didn't like.

Doing USB over IP is an interesting way of re-creating that work (although mine was multi-master so technically a bit better :-)). Of course these days USB 3.0 is faster than the ethernet port on most machines so it was no doubt doomed from the start. But its fun to do. The SATA over Ethernet stuff that CoRAID did was like that, very nice work.
It boggles my mind that I don't see more material about Instructional Design and the work done by Gagne in education discussions. These are extremely powerful theories with deep practical application, well-known in some disciplines. But CS Education heavily underutilizes them.
How was it received?
that has no relevance here. Germany vs North America for gods sakes.
It's easier to see what's going on around you, and you can hear better. I don't consider this worth the risk of head injury personally, but the difference is there, and it's noticeable, particularly vision.
No, the drivers and cyclists in NZ are almost at war with each other for some stupid reason, the same as plenty of other countries I might add. I'm just saying that people get over what prejudices they have about cycling with a helmet.

NZ isn't an island (chain) to the east of Australia, Australia is a continent to the west of New Zealand :P
Never, even at low speeds (this applies for cyclists, too). But apparently the argument is that motorcycle riders will approach their riding with more caution. To a certain degree, I will agree (when I wear less gear and no leathers, I ride with paranoia set to 80%, and assume the car behind me is going to drive with the intent of attaching me to the front bumper).
I say no fines for not wearing a helmet. It is only an excuse for local law enforcement to make more $$.

I think you should wear a helmet, but I think it is ridiculous for the government to require you to wear one.

Same with seatbelts, frankly.
Another interesting thing to study would be whether cyclists change their riding behaviour when required to wear a helmet. Similar to the effect on driving behaviour of mandatory wearing of car seatbelts.
A standard feature of all ladder-based competitive systems that I know of (video games, etc), is automatic matchmaking. Chess.com has it and Lichess does not, and that's keeping me from wanting to switch to Lichess.

I don't really want to have to select rating ranges. I don't know what ratings to play against, and I definitely don't want to think about it every time I make a game.

It's all about the scale. Grossly speaking, on an average, Eiffel Tower is perhaps 99.999% air. But is this true at every scale? Does every cubic meter of the Eiffel Tower have 99.999% air? Or does every cubic micrometer? If we were to build a megastructure of size 1,000,000s X Eiffel-size with Eiffels as the building blocks being replicated, then perhaps the Boeing material is not super-useful. But most applications are 1,000,000s X the Boeing lattice sized.
Very much appreciate your feedback! We are working on polishing it and making it private beta. To be honest, we need a lot of help, as well as a lot of feedback. Although this post was a hope that people will provide feedback on deep-framework, I completely agree with you that it would be great for www.deep.mg to be also fully functional, which is not right now. Can I ask you to send an email to beta@deep.mg, so I could notify you when we have the public beta instead?

You want to talk about failure modes? The nuclear "worst case" has nothing on hydro.

Hydro power is responsible for the most fatal electricity generation incident ever: Banqiao Dam. It catastrophically failed and killed an estimated 171,000 people.

Fukushima was a flea bite by comparison.
Kind of where I live.
It's also somewhat less tiring to eschew the helmet, but I similarly always wear the helmet anyway.
Ocean floor disposal (also know of Sub-seabed) seems like a quite reasonable way of getting rid of nuclear waste you don't want to see again. Load it into a giant dart, drop it from a ship, allow it to pick up speed as it drops to the ocean floor, and it buries itself deep in the ocean's clay. It helps deal with concerns about access to the waste, as the number of submersibles that can work that deep is likely very small.

https://en.wikipedia.org/wiki/Ocean_floor_disposal
Helmets reduce field of view, reduce hearing, and may make a rider "feel safer" which can lead to carelessness. Don't know if statistics back any of that up, but those are the common reasons I've heard. Better to avoid an accident than survive one.
I think the Javascript framework of the month fad is a complete waste of time.

Sure. Developments get abandoned all the time, either because they run out of time and money or because economic conditions change. One I was reading about recent is the Fontainbleu Resort in Las Vegas[1]—the second-tallest building on the Strip and unfinished.

And even more developments end up hilariously past their budget on both time and money. "Megaprojects" like the Big Dig[2] are common examples of this.

These are the failures big enough to be notable. I'm sure there are far more smaller, less interesting but more indicative failed projects as well.

Workers occasionally fall off roofs and turbines. Not often, but often enough for them to cause more deaths per kilowatt than nuclear power.
As I understand it, making helmets compulsory makes people use their bikes less, making them get less exercise, shortening their lives more than they would have saved (statistically) by wearing a helmet.
Unlike most bicycle helmets, typical full-face motorcycle helmets impair your ability to see and hear what is around you. It is actually illegal in some jurisdictions to drive a car while wearing a motorcycle helmet for this reason. Because most motorcycle crashes are the result of the motorcyclist being hit by another vehicle, no helmet means you have a better shot at avoiding an accident.

That said, I wouldn't go near a motorcycle without a helmet. You're going to fuck up and hit your head eventually.
Coal mining kills hundreds without accidents.
Updated, sorry, they almost seem like the same API to me—I've never used one without the other. I have no idea whether that's actually the case.
No need to be curt. He's simply saying that if Amsterdam is a much safer and convenient city for cyclists, one would expect both higher participation and lower incidence of injuries. A comparison of these metrics across these two cities would therefore be dominated by non-helmet-enforcement effects, and therefore it's more difficult to tease out the causal relationships than to simply compare the top level statistics.

I actually used Functional Jobs to locate a job with an established company that was creating an internal team set to use exclusively a functional language. My experience was not good at all. It turned out that they meant that they had acquired a start-up that made their own proprietary functional language (from scratch, not even building on the parser or lexer or anything from previous languages). The team also said, with a straight face, that they didn't believe in unit testing -- like, they didn't believe that it was even in principle a reasonable thing to do at any time.

It really opened my eyes to the fact that when someone claims their team uses "exclusively functional programming" that person actually may not even know what immutability or algebraic data types are. I had always been working on an assumption before that there was a vague correlation between wanting to work with functional techniques and being a quality-minded engineer -- but my experience after getting a job from a place that posted on Functional Jobs totally changed that. I try to be way, way more skeptical now, which is why I am quite skeptical that Jet is using F# more as a hiring trick than as a true engineering ethos.
"All" that needs to be done

"Those nerds" aren't the ones calling the shots. The decisions are being made by the same people who want the company's original 1970s COBOL application to keep running until the heat death of the universe. "Those nerds" would rewrite the thing if they were allowed to, but they're not.

The Web has the same problem with ancient deployments that management thinks should just keep working unchanged for decades. The problem hasn't been solved for the Web, and also hasn't been solved in other fields, hence you still see listings for COBOL programmers.
At ~ $150, that is an expensive solution, IMHO.

Not a very well informed article, but it starts from a bad premise and just follows it along. The big reveal of "But flaws in the program were becoming clear: nuclear plants were expensive to build, produced waste that was impossible to dispose of safely and generated power far more expensive than had been projected."

Is not even wrong, but I don't expect the author to do any research about the costs of nuclear power, nor to track down cost inflators (regulatory delay, post start regulation changes) or disposal methods (reprocessing, vitrification, incineration) or cost per megawatt.
I would love to see this develop into a widely adopted standard. Apple uses a similar technology with their Airport Express devices for printer sharing, always been annoyed it was so restrictive in being able to connect to it.
