I commuted by public transportation for about 5~ miles each day before and after school from the age of 9 (in Ukraine). From 11 on I commuted about 5~ miles each way to school in New York City.

At 8, I would often walk for miles in the wilderness when out camping, or go swimming in a river without serious adult supervision.
Have you seen the images? That's clearly not true. When pressed to identify the so called "eventgoers" the leaders of techweek came up empty. just a bad excuse.
iirc, drowning is the #2 preventable cause of death in kids, after car accidents.
I, personally, don't believe that children should ever be left alone in a car, but I'm not sure where the legal line should be drawn.

On one extreme, it would only be criminal if a child dies under your care, which would be criminally negligent homicide or something similar.

On the other, we can't run in to drop a movie off at RedBox without getting 3 kids out of the car.

I wish people in positions of authority were able to apply more common sense and wisdom than always involving the criminal justice system.

My wife knows a lady that does (unlicensed) day care, and she leaves kids in the car all the time. She just tells them to hide so no one sees them. As far as I know, none have been injured, but it's also pretty irresponsible and I wouldn't allow her to watch my child.
> Laws are made by lobbyists and enforcement of those laws, sometimes involving judgments of billions of dollars seem to rest on some good ol' boys in some dingy Texas courtroom.

It's not nearly as bad as you make it sound, but there's certainly a kernel of truth to it -- not just in patent law, but in law generally. For example, look at Tesla Motors having to contend with state laws protecting car dealers, and Uber and Lyft with taxicab laws, and AirBnB with hotel laws, and craft brewers with alcohol-distribution laws. All those laws have at least some "rational basis," but it's no secret who pushed to get them enacted and who pushes to keep them in force.

In law school, I had a hard time getting my mind around that brute fact: Power matters, even in the legal system; no matter where you go, people push to get the government to (i) help them do what they like and (ii) stop others from doing what they (the pushers) don't like. I tell my students not to be disillusioned or discouraged about that, but to accept it for what it is; plan around it; and get on with their business. [EDIT: I agree with the sibling commenters who say that in this regard the U.S. is way better than a lot of places.]
I don't mean this in a trolling way but do you really think the US population overall isn't going to be taller and heavier from 1927 till today?
If IBMs stock price were nothing more than uninformed public opinion, then it would have been plummeting for what, the past decade? Most non-technical people don't know IBM still exists (they nearly entirely disappeared from the general public's view when they stopped making consumer products); and most people in the trendy half of the tech industry seem to think that IBM is not long for this world.
You cannot leave a four year old alone in a car and trust that they will not get out. Nobody's four year old is trustworthy; they are not biologically capable of being trustworthy at that age.

Meanwhile, a four year old escorted through a parking lot with their parent is at least somewhat visible. A four year old alone in a parking lot is invisible.
Exactly. Based on reading some of his previous essays, plus many other sources that are seeing the problem, "In 2010, Rometty’s predecessor, Sam Palmisano, pledged that per-share earnings would reach $20 in five years, a plan called Roadmap 2015. (http://www.businessweek.com/articles/2014-05-22/ibms-eps-tar...).

So part of this policy is an explicit pledge of the company. How it's being achieved, or attempted, is of course another story, as well as, say, whether everyone should dump their IBM stock once it reaches that goal, assuming enough greater fools can be found....
How does* Krebs get into these sites? How many alternative names does he have? Does he spend months gaining people's trust to get into these sites? It amazes me, he does such a great job for the community. Does he take donations? I want to give back for all the stuff I've learned from him.
Spot on. Reaching out to your earliest users directly - and not via a canned email - is really effective for building trust and loyalty in a community. Communities are often a reflection of the founder him/herself and this sort of grassroots outreach goes a long way toward attracting others.
BlackBerry sales were also up even after the iPhone came out. Even after the Android first hit the market too.

Now they're pretty nearly dead - and I don't think there's any doubt that it was iPhone and Android that killed them. Sales and stock prices often lag behind a real inflection point.
Are you a current ex-IBMer?
It was worse than that. Someone wasn’t worried. Instead of acting, by, say, trying to talk to the kid in the car or perhaps just calling the cops, they “recorded the incident using a phone’s camera, and had then contacted the police”. Baffling.

By the way, this is what I think of every time I hear someone use the phrase ”a good samaritan”: https://www.youtube.com/watch?v=OIVB3DdRgqU
I've been a fan of Jumpshare for this kind of file sharing, but it got all fancy and now you can't drag/drop files if you're not signed in. Really good for sharing groups of files, managing the content you upload, etc, but not so great for super-fast file sharing. I may use this instead.
I'd say that the Supreme Court isn't so much correcting bad laws as correcting bad Federal Circuit interpretations of the law.
Citing stuff from the 80s RISC movement is pretty outdated nowadays, especially in this specific case where quintessential RISC architectures such as MIPS implemented trapping arithmetic instructions from the start.
I like the conclusion of the article, which is that concentrating all patent cases into a single court has given that one court too much power. That particular court seems heavily pro-business right now. The legal system works better when appeals court judges across the country make decisions, and the supreme court manages the splits.

Not sure if it's true, but it sounds like it would avoid the concentration of decisions in one bad court. We see that in "West Texas" patent lawsuits as well. One rogue court can affect the nation.

Very nice, much faster than simulating it. I guess if you're using an informative prior, instead of adding 1 to the number of successes and failures, you add the corresponding parameters of your beta prior?

A pretty good shortcut (if you don't have a log-beta function, for example) is to approximate both A and B with the normal distribution. Then their difference is also normal, so you can just check the probability that a normal random variable is greater than zero.

Specifically, the mean μ of a beta distribution is α/(α+β) and the variance σ^2 is αβ/((α+β)^2(α+β+1)). Use these as the parameters for your normal approximation, and we have the difference D ~ N(μ_A-μ_B, σ_A^2+σ_B^2). The probability that B beats A is just the CDF of D evaluated at 0.

In Python:

from scipy.stats import norm as norm

def beta_mean(a, b):
return a/(a+b)
def beta_var(a, b):
return a*b/((a+b)**2*(a+b+1))
def probability_B_beats_A(α_A, β_A, α_B, β_B):
mu = beta_mean(α_A, β_A) - beta_mean(α_B, β_B)
sigma = (beta_var(α_A, β_A) + beta_var(α_B, β_B))**.5
return norm.cdf(0, mu, sigma)
The current Supreme Court is pretty rogue itself.
If you have a bug in the wrapper, you fix it once in the wrapper, and it's more likely to have shown up in a test if that wrapper is used multiple places. There is no static guarantee that you wrote the wrapper right, but hopefully there is some guarantee that you used the wrapper right. Definitions can't outnumber uses (or errors in some of those definitions don't matter...).

There's no specific law against it in the majority of US states (http://www.kidsandcars.org/state-laws.html) The laws against leaving a child alone in a car are stricter than leaving them home alone (http://www.imom.com/parenting/tikes/parenting/safety/home-al...) because children dying of heat stroke in cars has made headlines in the past 20 years.

Many laws in the US are purposely vague and up to the interpretation of the police. The mother was charged with "contributing to the delinquency of a minor" (http://legal-dictionary.thefreedictionary.com/Contributing+t...), which can be used against anyone that does something that might possibly result in a child being adversely affected in some way.

The unfortunate part of life in the US is that the average person breaks a few dozen laws every day, and it's really important not to upset the police in some way that they'll take notice of you and start charging you with crimes.
nice read. especially about determining the candidates baseline and assessing how fast they grow from there.
You can't have your child out of your sight for a single instant without a chance of them getting hurt. When you are asleep they could easily leave the house and get run over in the street. I'm generally a fan of your comments but this time I don't see your point at all.
Mmm, any reason you're not using Django's class-based views (or http://django-vanilla-views.org/) for DRYer code?
Bolivia here - I've NEVER in my 14 years living here in two different departments (states) seen a child left alone in a car. It's just unheard of. And we don't even get that much heat or cold either.

The risk is someone can break your window and steal your kid. It's just something that's never done. It would be akin to leaving your child on the street corner while you go up to your apartment to grab the purse you forgot.
I asked my SO, "What would you call an app that would let you connect instantly with anyone else using the same app?"

metal-air batteries (fuel cells), rechargeable and not, is the future. Having comparable to gasoline energy density, yet higher efficiency - 60-90% vs. 30% of gasoline, it will transform cars and especially planes (subsonic ones). You can imagine that it is absolutely not an issue to replace a 100Kg spent aluminum fuel cell block on a small plane at airport. It would also be better than gas turbine for bigger commercial, though still propeller driven, planes (for pure jets the issue is that you need air to be hot to have high exhaust speed for the plane to reach speeds beyond 450+ knots). Interesting possibility for decreasing heat
signature for military subsonic drones too :)

There is also very active development for rechargeable metal-air batteries though currently it is significantly skewed toward lithium-air which is non-starter pretty much. There is very promising results with zinc, sodium and especially potassium -air batteries.
I figured people would push back but I really don't see how. Everything about this company sounds totally screwed. It's funny that you bring up Blackberry because what you're saying now is pretty much what people were saying about Blackberry in 2011 or so.
I work for IBM's new design group and honestly I'm pretty optimistic about the future of the company (and I'm a generally a pretty big pessimist/realist). Aspects of the company have issues but many of those are being fixed/changed.
I don't agree with tptacek on this (at all), but front doors don't have child locks and it's trivial for a child to crawl up to the front seat.
Ask yourself: How many kids are killed annually by being left alone in a car, and how many kids are killed annually in car accidents? I have no doubt that the number killed in car accidents is vastly higher.

So which is the biggest sin? Which should be the crime?
> ... a hodgepodge of laws that attempt to prevent yesterday's headline.

Oooh, nice, I'm going to steal that line.

Relatedly, I think the person I'd be happiest to vote for in this day and age is someone who will introduce no new legislation, but just spend their time getting old pointless laws off the books.

Think of it as an extension of "The best code you will ever write is… code you never write."

OP Cites Judge Prost's dissent in Alice, "The majority has failed to follow the Supreme Court’s instructions—not just in its holding, but more importantly in its approach."

But that was about the awful judgement of the three-judge panel. The ruling was reexamined by the whole CAFC and a 5-5 hung court could not decide weather to keep the ruling intact. Until the Supreme Court rules, that 5-5 non-decision is the final word. Any rational decision by the Supreme Court -- concluding that Alice's patent is invalid -- will not be considered a reversal.

Also, it is considered unlikely the decision will reach the question of software patent eligibility. It will probably turn on abstract idea or business method eligibility. The patent monopolizes any use of computers in handling escrow accounts.
Machine Learning and the Fourth Amendment
That's not much help for kids who do have abusive or neglectful parents, is it? They're citizens too and if they're stuck in a dangerous situation they're entitled to the same level of protection as any other member of society.

there's a middle ground between the state as inflexible guardian and complete parental sovereignty.
And I am not advocating for a parenting strategy that demands total attention to your children 60 minutes out of 24 hours a day. I'm simply saying that one time you can't let a child out of your sight is when they're in a parking lot.

Let's make this simpler: would you leave your four year old alone in a parked car for 5 minutes while you ran into a store?
You make some good points about parental rights.

Look at vaccinations. (Vaccinations are good; I had no hesitation having my child immunised; I'd like schools to require immunisations for pupils; etc). The early days of the vaccination scandal were not presented as a bit of scientific research, it was "you, as a parent, are harming your child by vaccinating them" (and that's still what the nutjobs are saying). Now that we know that Wakefield is a crook we tend not to say "you were duped by a crook who had financial interests in misleading you so let's help you get your child immunised", we say "you're a nutjob and a bad parent".

Look at HN where parents feel guilt about work life balance for one example of how hard it is to be a parent in a rich first world country.

Look at the number of people on HN who (ignoring law) say they would hesitate to employ women because of the risk of maternity leave.

The fact that "having a child" has to be written into legislation as a protected status shows that status of parents was seen as needing protection.
Amazon will finally unveil its 3D smartphone on June 18th – Yahoo News
Correct, they use parimutuel betting, where all bets are placed in a group pot and the winners are paid their original stake plus some portion of the losers' stakes. This means that bitbookie doesn't have to set betting lines (probabilities) for all the events, which is something that takes a lot of skill and effort. Essentially it's easier for those who are not familiar with sports betting to say 'I pick team A to win' as opposed to 'I think team B is going to lose, but not by more than 7.5 points, so I should bet on them even though they're the worse team" that is a common play in spread betting.

while this isn't 100% inaccurate, one major headache are vague rulings from SCOTUS. the "reasonable certainty" test is a good example as well as their "abstract means abstract" pseudo-standards. while SCOTUS paints with a broad brush (rightfully so), many of their decisions are borderline meaningless other than to say to the CAFC "no you're wrong," which results in multiple rounds of these type of decisions (often on the same issues, or variations of them). that being said, the closeness of the CAFC to the bar is quite troubling and the e-mails that Rader sent to attorneys who argued in front of him were pretty embarrassing for all involved.

Do you have any numbers to support that assertion? I'm interested in what you consider to be "a substantial number"
Windows has had virtual desktops for years. There's a Desktops powertoy for this.

http://www.makeuseof.com/tag/power-toy-microsofts-virtual-de...

It's not built in functionality which makes a lot of people irate. The thing is nobody would know what to do with it on Windows. Windows users aren't taught about multiple desktop session, virtual desktops, etc.
dabernathy89,

Thanks for the feedback! We sort of felt the same way. Honestly, we wanted something fast and easy and you're right, going heavy on the UI just slows things down. We're HUGE fans of keeping it as simple as humanly possible. :)
I think IBM is big enough to be both incredibly stupid and smart at the same time, depending on where you look.
Just using my own example, it's roughly a 5x increase in CPU time for a > 10x reduction in disk space (and commensurate reduction in disk IO — including writes, which is an important consideration when you're using SSD). Let's just say 10x though, for sake of easier math.

Assume $1/gbyte storage costs. We're not talking about consumer-grade drives here, right? It's probably worse than that anyway, because you're using some form of RAID, too. Aren't you?

Assume further a $1000 8-core CPU, as that's what the machine in my example uses (it's actually slightly more expensive, but again: easier math), and a 3 year depreciation schedule. That's roughly 1000 days, or $1/day, $0.125/core-day, or $0.000087/core-second.

Storing that log file uncompressed costs you $8.817 in storage, and $0.00085 in CPU time, if the process uses 100% of a core for the duration. Storing it compressed costs you $0.828 in disk space and $0.0038 in CPU time — again, if you're burning an entire core for all 44s.

I think $0.8318 is less than $8.81785, but feel free to check my math...

EDIT: Yes, I know I'm conflating the ongoing cost of storage and the incidental cost of CPU time. I'm also ignoring the cost of power and cooling, leaving entirely aside the difference between storage milliseconds and CPU nanoseconds, and, and, and. I guess, if it's not obvious that compression is pretty much unequivocally a win with modern CPUs, then I don't know what else to say.
Uh, OK. I use "recent" to denote that I've only recently become an ex-IBMer, so my knowledge of the company's workings are perhaps more relevant than someone who left 10 years ago.
No, society should protect children. As you say calling the police is okay, but the reaction of police is not okay.

First, it was 3000 kilometers, not miles.

Second, the energy source is the oxidization of Aluminum. It takes specific preparation (e.g. thermite) to release that all at once. The contents of this "battery" are as safe as carrying around a bunch of crumpled up beer cans (very safe) and whatever the heck that solvent is (unknown). The solvent may be toxic, acidic, etc. but hopefully no worse than what's in your car battery, which is actually pretty nasty but not terribly dangerous unless you deliberately try to make it so (e.g. by shorting out the terminals).

Aluminum is currently under $2K/1000kg, so the yearly aluminum battery replacement would probably run a few hundred dollars. Aluminum is the most abundant metal on earth and this reaction is reversible, so costs should stay low. The real cost is likely to be the solvent.
Objective-C has added several features in recent years; things like bindings, dot notation, etc. are relatively new, but pretty substantial changes in terms of code clarity.

As for Python 3, the Python community never intended for people to move over to Python 3 immediately, nor was it intended for people to move their Python projects from Python 2 to Python 3 unless they had some reason to (e.g. Django, public libraries, etc).
Except for the fact of their code of conduct.
> The batteries are "charged" not from the electrical grid, but from hydroelectric power generated at Alcoa's smelter in Baie-Comeau, Que., Tzidon said. When they are full-charged, they are thick, heavy panels made mostly of aluminum.

In a sense it's green if they are produced from green energy, like hydroelectric power in remote Canada. In that case it's not just green because it's hydroelectric, but also because it's inconveniently located hydroelectric it's not displacing more productive uses of the electricity. Maybe geothermal energy in Iceland would be another option.
I am temped to do Bill Gates here and say: 64bits should be enough for everyone (in the common case). If not - using SSE like maths it's an option too. Using bignums by default would make everyone suffer - they do come with a price and the hardware can't support such a bizarre beast naturally.
