I'm not suggesting they should. My alternate solution was a toll based system where the trucks would pay extra for roads that can withstand the extra weight.

You could just increase the weigh station fees, but then you'd have to make all the lanes be able to withstand the extra weight, and you wouldn't have the extra benefits of safety (a car doesn't stand a chance against a truck in an accident) and efficiency (trucks can't accelerate/decelerate as fast as cars, so they contribute more to traffic congestion).
Ask HN: Machine learning for predicting cricket matches
While i am still learning machine learning' basics, i thought of doing it through some application. I am big cricket [https://en.wikipedia.org/wiki/Cricket] fan, given the records we have about each ground, each player, each team, and also very limited number of teams, 10 or 12. It would be good exercise to build a simulator which tries to predict a game's output, I will run it for just happened games, then try to compare. Any good place to start ?
Ask HN: Should I implement Sign in with LinkedIn?
I am building an application for prospective and professional writers. I was thinking of using both login with Facebook and LinkedIn for signing in. I was thinking of LinkedIn especially because of the level of professionalism it could bring. However, when I looked at stats about LinkedIn, its apparent that it is nowhere near as big as other social platforms, like Twitter. How should I go about this? Should I emphasize on the philosophy of the company or what the service actually offers in its current state? I don't want to offer so many methods of signing up or logging in; ideally two at most. Thanks in advance.

The other response cover the WTF WRT specifically web based company, I propose the general response of people aspire to getting actionable analysis. Companies don't actually have to provide actionable measurable quantitative analysis results, they just have to promise it could happen.

My personal experience with Quicken and Mint is I never got any actionable measurable results from the effort. Yes I saw all the ads about how I'd get special offers to save $5 on my car insurance or it would make me save for retirement or whatever, but over many years of Quicken and a couple years of Mint it never amounted to anything valuable. Then it becomes an insurance and sunk cost game, well, I've tossed away all this time and effort to organize unnecessary data, I guess I need to keep going to "save" my sunk cost. Eventually I chucked them both. The minimal time to maintain adds up over time and cuts into actual analytical analysis (not to mention recreational time) and in return, as mentioned, I got nothing out of it. Not all aspirational products are worthless to all people, I'm sure there exists someone who got something measurably important out of their mint or quicken experience. Just not me or anyone I know.

The dieting industry makes people feel they're doing something important when they pick up a book or try to live off nothing but grapefruit juice for three days; all that really happens in the end is the provider makes money.

That's valid, but the nuance I left out of my comment was the common conservative belief that the government is simply too big, and that by cutting taxes, we can starve it back to an appropriate size. Many conservatives would not be happy with a more efficient mechanism to generate the same revenue we get today.
As a fellow very busy programmer I can easily see where you're coming from, but surely for several years time a background task must be pushed to the highest prio tickets eventually?

Perhaps this is what you mean but I'd add an additional difficulty - we can't predict the organismal impact of many of the genetic manipulations we make.

As a result of this, we must perform time-intensive experiments using model organisms like bacteria, flies, mice, etc.
I grew up in the UP, but never picked up a strong accent (my parents had moved there). Visiting rural Ontario was a quite amusing experience, the use of eh in the UP is occasional and often ironic, in the area I visited, it was punctuation.
The reason they didn't do that is because this wasn't an official VA system and their employees weren't meant to be using it: http://www.militarytimes.com/story/veterans/2015/08/21/conce...

Basically, it seems Microsoft designed Yammer so that any employee of any organisation can start/join a Yammer network for their employer just by using their work e-mail address. If the employer then wants to actually administer the internal social network that they've unexpectedly wound up with - for example, to remove ex-employees - Microsoft charge them a substantial monthly per-user fee.

Wow, I actually got down voted on this. So, let me clarify. There's an interesting case study of a woman who does not experience fear at all due to brain damage:

http://news.discovery.com/human/psychology/fear-fearless-bra...
https://www.psychologytoday.com/blog/extreme-fear/201012/the...

While on the one hand, there may be cases where a lack of fear may be beneficial (and for some people, fear may be debilitating--for example, for those suffering from PTSD)--it can often act as a useful check on dangerous impulses. So, while I'm excited by the positive potentials here, I think that one has to be aware of the potential downsides.

Removing Signup from Devise in Rails
It happens quite often that bugs end up being obscure things like this.

The a-ha moment when you've figured one out is interesting. It's always a mixture of pleasure at having discovered a complex causal chain and horror at having written it.
There are lies, damned lies, and statistics.

Moose are involved in around 80% of fatal vehicle-animal collisions in the state of Maine over a five year period[1]. Clearly, moose are a menace, and we need to dramatically invest in moose-diverting safety features on our roads!

Except... moose-vehicle collisions were only 15% of all animal-vehicle collisions. Even a cursory look at the physics of what happens in a moose-car collision explains why moose collisions are disproportionately fatal. Look at a moose, standing next to a typical compact-to-midsize car[2]. Now look at what happens when that compact-midsize car hits a moose[3]. The animal's legs get swept out by the hood/bumper of the vehicle, and the animal's heavy body crashes down through the windshield and the relatively flimsy roof of the vehicle, crushing the driver.

A similar thing happens with semi trucks. In many cases, the front bumper of a truck, and the rear bumper on the trailer, are higher off the ground than the hood or trunk of a car. So if a truck is involved in a rear-end collision with a car in front, as often as not the truck goes right over the top of the car, crushing the occupants of the car underneath.. Or if the car is rear-ending the truck, the hood and engine mass goes underneath the trailer, but the windshield and roof is sheared off by the steel bumper and trailer deck, along with the upper portions of the car's occupants.

I'm not sure you're going to make those physics much safer.

It's a reasonable choice if you want to show market share at the same time as market growth. Considering the example of browser statistics, you could imagine a graph showing the total height growing considerably over the years while the height of some browsers remains static (or even shrinks).

If the overall height grows and some browsers remain static, that means the other browsers likely didn't "steal" any of its market share, they were just better at attracting new users.

why aren't people just Kickstarter-ing cannabis
decriminalization, marriage equality, and
copyright law changes?

I would imagine it's a lot cheaper to bribe a politician when:

1. The bribe doesn't get any publicity/press coverage/cause any embarrassment. Campaign donations from big corporations are "business as usual" and the politicians don't look corrupt in the press - but do the same way in a public, attention-grabbing way and the guy looks bad if he accepts.

2. The vote you want to affect is low key and doesn't contradict the politician's public position on major issues. Changing a politician's opinion on the Concrete Masonry Products Research Education and Promotion Act of 2015 would be much cheaper than changing their opinion on overturning Roe vs Wade

3. You want to maintain the status quo. Creating new legislation and getting it through the system is a bunch of work - compared to turning up on the vote day and saying 'no'.

4. There are future votes and future bribes to look forward to. If I give a politician $200,000 to vote a certain way, he might take the donation then vote a different way - and if I ask him to vote that way and promise him the money afterwards, I might refuse to pay after he votes. But if there are 10 votes and I donate $20,000 before each one if he voted how I wanted in the last vote? Then neither of us can screw the other over too badly because we know we'll be making the same deal next year.

5. There's aren't other well-funded lobbyists bidding against you. Because if there are you'll need to get into a bidding war and they might have a lot of money to throw around. If people who vote against copyright extension get $20,000 from me but people who vote for it get $50,000 from Disney I'm going to need to up my game - and Disney probably has pretty deep pockets.

TLDR: I'd expect cannabis decriminalisation or copyright law reform to cost a lot more than blocking tax code simplification.

With that said, if someone would like to organise an attempt I certainly think it would be interesting to see if a kickstarter-like approach would work.

I visited your page expecting to see details of a testing methodology, along with results for a number of providers. However, the information you provide is no better than that provided by friends' anecdotes.

"Reason for Recommending: Reliable connection, fast speed. Fast customer support."

What do you mean by 'reliable'? What do you mean by 'fast'? Are you talking about latency or throughput?

"Reason for not recommending: sometimes hard to connect"

How many times out of ten? Using which VPN protocol(s)? Was this using PPTP, or OpenVPN over stunnel?

I run my own VPN servers (for myself and friends) but of course there is some ongoing maintenance effort to add new servers to replace those for which latency and/or throughput have declined. If there were a site with specific data about different companies' performance (over time), that would help me to decide whether it's still worth the effort.
If I can elaborate on that concern a bit: if government is allowed to be loud about transfer payments and quiet about taxes then it can successfully bribe the middle class with their own money.

It is entirely possible to run a tax system without W-2 employees having to do a return at all. Many nations do it. American conservatives strongly prefer a government which is not sized like the government of those nations.
Note: that video is from 2011, and in my experience China's VPN blocking has changed significantly over that time. In 2011, I could use OpenVPN over UDP reliably, as long as I didn't use the same port for every connection. That is no longer the case, and I'm grateful for Shadowsocks as it's easy to set up (both server-side and Android client) than OpenVPN over stunnel.

My only hope, with regard to genetic engineering, is that the people who are actually discovering this stuff are strong enough to prevent large corps from patenting all of the most important intellectual property that will empower future generations.

My active imagination hypothesizes that the people who go to work every day to invent / discover this stuff go to work only with the meager hope of collecting on their 6-figure salaries to provide for their families and pay their children through higher education. Perhaps even a stint at an Ivy League school. Meanwhile empowering large multinational corporations / conglomerates with the enormous wealth of intellectual property that their grandparents would be ashamed of.

This is perhaps why these things don't get fixed. A Linux user does not see this as a problem.

This is a problem for someone who is not a Linux user.

City Guide
Having seen a lot of the content that goes through these products, from the compliance side, I'm not sure that they are particularly "productive." Where they have any uptake at all (surprisingly rare, for such expensive products, that require so much work to implement and roll out), it's pretty... meh.

It seems like "social" is a buzzword that is finally starting to lose it's luster, but it was pretty ridiculous for a while - IBM changing the name of Lotusphere to IBM Connections, all of these business Facebook-clones, Microsoft spending a boat-load of money on Yammer, then letting it languish, while building more or less parallel features into SharePoint and Office365.

So much hype about "transforming the way people work" and some truly disturbing rhetoric about enabling the blurring of personal and work life. Good riddance.
>If $2.3MM/yr over 5 years is enough to reshape the trajectory of fundamental laws in this country, why aren't people just Kickstarter-ing cannabis decriminalization, marriage equality, and copyright law changes?

Not all political battles are equal.

1) There are lobbies dedicated to keeping cannabis illegal and marriage unequal. There aren't any lobbies dedicated to keeping taxes simple.

2) It's easier to kill proposed legislation than it is to propose new legislation and get it passed.

Just to nitpick I think they refer to supersonic speeds in standard pressure. The speed of sound in very low pressure ("vacuum") is much lower and they probably far above that.
Interesting idea. It should be only a few lines in PyOpenCL to build something like this.

But if you're already in PyOpenCL I guess would also prefer to generate the bin files there (maybe using numpy) ans evaluate the output (matplotlib possibly). For optimization you could run the kernel in a loop, time the runtime and vary the number or global and local work groups.
I would never watch a 7m youtube video about this topic. I simply don't care.
But the point is that they shouldn't have set the timeline until a replacement was reasonably in place. They could (and should) have said "this is going away 12 to 18 months after we've been able to determine what APIs are needed and implemented them".
I currently use a mixture of PPTP and Shadowsocks. Shadowsocks (even to the same servers) seems to successfully connect a little more often, and drop a little less often. Otherwise, performance seems similar, and goes up and down.
GR's conceptual model is fairly clear. It's completely unintuitive and hard to understand. But - so far at least - it's not open to multiple competing interpretations.

QM doesn't have an agreed conceptual model at all.

Stuff happens, and you can predict it statistically with a lot of accuracy. But the math doesn't reduce to a physical explanation that makes sense and everyone agrees
on.

No one knows if a wave function is a physical thing, or if there's some other physical process which defines the wave function, or exactly how a statistical process with spatial and temporal indeterminacy gets turned into a physical observation.

These are all complete unknowns. And you can't say you understand something when you have equations that work, but no idea how or why they work.

This matters because when a scientific revolution happens the conceptual model everyone uses is transformed. The math tags along behind as a proof of consistency and accuracy, but it's not the primary driver of change.

If you don't have a conceptual model, you're stuck.
