The difference is like this: A 5 dollar plastic keyboard vs. a handmade $1000+ keyboard with mechanical switches.

The very first Lisp Machines were handmade $100000 pieces of hardware. With wire-wrapped boards made of zillions of low-integrated chips and various other components. Huge power supplies for several KW worth of electricity. Really everything was specially made, like 25m long console cables with signals for monitor, mouse, sound and keyboard.

This can't be a Show HN until people can actually play with the software (so we've taken "Show HN" out of the title), but it's still a good article.
It wouldn't be only a beneficial outcome, it would be the best and the only morally right outcome.

Consider that before the advent of software, people actually owned the things they bought. And you could argue that it isn't fair to impose such standards on markets that haven't existed before software and you might be right, after all people have to eat, but when it comes to automobiles people have historically owned the car they paid for. And in practice what this meant is that they can get it inspected and repaired by third-parties should they want to do that, which means longer lifecycles and cheaper service, among other side-effects that come as a natural consequence of actually owning things, a freedom that is essential for the proper functioning of capitalism itself.

But now with the advent of software in these computerized cars all of that is about to change. And lets place that in the context of the never ending copyright terms, with the excruciatingly low threshold for awarding patents, with the price of IP lawsuits going through the roof, along with the fact that software leads to natural monopolies. As that's the context we live in, a context in which innovation happens only because the giants whose shoulders we stand on haven't protected their "IP".

And I get it, we are software developers, we've got to sell our labor, but nothing makes the stealing argument any less bullshit. And we could start from stating the obvious, which is that copyright or patent infringement is not stealing.
If the DMCA doesn't take care of it, there's always the right to be forgotten.

Ask HN: Are auto login tokens in transactional emails bad practice?
Hi HN, what do you think about auto login tokens in transactional emails? If the user has multiple devices (e.g. desktop at work, ipad at home) it's just very convenient. We also offer login with social accounts (e.g. facebook, google) but most of our users still register by email.

Whats your opinion?
The stoichiometric mixture of air and fuel burns exactly all the fuel. You can run richer than stoich (lower air-fuel ratio), which will produce more power and run cooler, at the expense of fuel economy. You can also run leaner than stoich (higher AFR), which will be more economical but combustion temperatures will be higher and more NOx will be produced.

Throw ignition timing in the mix and you have a complicated balancing act that engine designers perform in order to produce the ideal combination of power, fuel efficiency, and emissions.
India to cripple its tech sector with proposed encryption crackdown
Force one, force all. The side effect being that if another manufacturer steals and reuses code under NDA, that'd show up as well.

Calling it "unrealistic" is unrealistic. These companies are not anybody's pet, to be loved and hugged and cared for. We should ask them to release their code, at least to regulation agencies under NDA, because otherwise they harm the health of millions of people for the sake of passing regulations, like in this very case. Don't know about you but I'm in no mood to give them a free pass on this and on top of that, worry about "oh but those poor SOBs, what would they do if their NDA'd code would get leaked"...

Sorry, this is a bit of a hostile answer and it's not meant to be - this entire ordeal is enraging... and I don't see why we should preemptively defend their rights to make money off our own health.

>> The question: why did the engineers implemented a detection of the test environment?

> Yknow, maybe because they knew they didn't have to worry about people reviewing their code.

You read the rest of the comment? You NEED to detect it to apply to correct algorithms for all those safety assistants.

Otherwise you could decide to just cool down when a door is open, when the front wheels are spinning, while there is no acceleration, when the distance sensors detect obstacles. But that would make testing impossible.

By purchasing a car, you purchase an end product, which is designed to be suitable for your purposes. You don't purchase rights to a million manhours of software, free to do what you will with. If companies had to amortise the cost of code development over the cars they sold, you would end up paying a lot more for 'your' car.
> In the UK at least, pretty much every car under £30,000 is utter garbage.

What?

Modern cars are of incredibly high-quality, even at the lower end of the market.

Take a look at what taxi drivers in the UK use. Today, the taxi fleets are dominated by Skoda[0], Kia and ( in London ) Toyota. Those all cost under £30,000. Well under. Yet they hold up well in the daily urban taxi grind.

Mercedes, BMW and other 'premium' brands are notable by their absence from such fleets. That's because they don't offer any quality differential correlating to their price. They mainly occur in the higher-tier occasional-hire market, aimed at people who want image.

[0] That fact that Skoda is preferred over the same parts wrapped in an Audi or VW body is interesting.

Google is only transitively punishing Wired through their exclusivity agreement with Apple News, where they both decided to wall it off, not anything about creative partnerships or Google ads. Plenty of Google results come from sites that don't use Google advertising features, and walled off content can remain just so.

There is certainly a discussion to be had where major sites are allowing Google to spider paywalled posts such that the content comes up in results based on hidden-to-the-rube words, but that's for another time.

[I am not an expert, but] first there are controllable emission control devices (e.g. EGR) and secondly burning conditions (thermodynamic cycle) highly influence power and emissions (emission mixture), i.e. how much power and emissions you get from burning 1 g of fuel.

An intuitive analogy: when you are camping (or just use firewood in a grill) and are just starting a fire there is a lot of smoke, although the fire is relatively small. When you get it hot and burning nicely there is barely any smoke left, although you burn much more fuel per time.

For an internal combustion engine the factors determining power/emissions are mainly fuel/air mix, ignition angle (gasoline), fuel injection pattern (for direct injection engines - all "modern" diesels, VW [T]FSI gasoline) and or air/mix injection angle (variable camshaft timing).

Fun fact: modern diesel cars have a DPF designed to limit emissions (fumes mainly). Engines have special DPF cleaning mode designed to kick in in highway modes by slightly increasing exhaust gas temperature. Driving only in urban cycles causes a DPF to get clogged, engine enters deep cleaning mode from time to time (power loss, dark fumes out of "chimney") which has a negative net effect on particle emissions, which are arguably most detrimental to respiratory tract.
This is crazy. Before this article, I hadn't even heard of BlaBlaCar before. Seems ride sharing is still a market with lots of potential to raise copious amounts of venture capital.
Adding to your question: who would accept a computer that only executed programs written in a single language? I remember people talking about CPUs that would run Java bytecode natively back when the Java hype cycle was near its peak, say 12-15 years ago. Never saw one on the shelf though, I guess once the JIT compiler started working well people lost interest.

> The four color theorem states (informally) that “given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color.” (from wikipedia). The mathematics statement is that any planar graph can be colored with four colors. Thus, the first part of the “warm up” has a solution; in fact the world map can be colored with four colors. The four color theorem is deceivingly simple- it can be explored by a kindergartner, but it turns out to have a lengthy proof. In fact, the proof of the theorem requires extensive case checking by computer. Not every map can be colored with three colors (for an example illustrating why see here). It is therefore natural to ask for a characterization of which maps can be 3-colored. Of course any map can be tested for 3-colorability by trying all possibilities, but a “characterization” would involve criteria that could be tested by an algorithm that is polynomial in the number of countries. The 3-colorability of planar graphs is NP-complete.

This is the background and context for the problem for kindergarten. It would be good if educators and writers could provide a version of this for young children and their teachers.
Can anyone explain why you might need to store queries as JSON data with horrifying syntax, instead of just writing plain functions that search/filter/whatever?

Or if you really have to, using a sensible DSL to do the job instead?
I can't tell if this post is serious, or making fun of the topic. I got to the point where the author thinks it's a good idea to talk about graph k-colouring with kids in kindergarten. Does anyone think this can have any meaningful discussion beyond a "you can colour any map with 4 colours" trivia?

Just as a reminder, these are points from the grade k overview:

- Know number names and the count sequence.

- Count to tell the number of objects.

I have the same issue with chat protocols. Some of my friends are on iMessage, some on Hangouts, some on Whatsapp. None of these talk to each other and I'd really just rather use TextSecure.

We had a standard for chat, it's called XMPP, and before that we had IRC. I know they're all non-optimal for mobile use but some goddamn standards (tm) would make my life easier.

I can't believe we were better off in the heydays of Trillian - at least all my contact lists were in one program!

Maybe I should go back to SMS.

Now, on home automation. I came to some of the same conclusions as the author - we're screwed when it comes to being at the behest of big companies and proprietary protocols to control devices we should own.

I just dread having to write yet another home automation framework when I do finally automate my doors, windows and lights. Now where did I put my keys again?
There's a class of hedge funds and independent traders that specifically search out frauds to profit off of exposing their malfeasance. The most famous of this group at the moment is probably Muddy Waters Research[1].

They look for companies that are trading at suspiciously high prices relative to their peers and then try to figure out why. In many cases lately, their targets are Chinese companies that "reverse-merge" with companies that are already listed on US stock exchanges. These companies are often partly or mostly fradulent and the "Fraud Cap" traders take large short positions and then publish their research to make immense profits off of the cratering share prices.

Their methods usually start with pouring over financial records but often involve boots on the ground too.. In one case, they hired people to literally count every truck that came and went from a factory that was claiming much more business than it was actually doing.

It's a fascinating part of the market and I think a net 'good' in the scheme of things but I think it'd be interesting if hedge funds started deep dives on published code in an attempt to profit off of security holes or intentionally dishonest emissions controls..

Muddy Waters has caused the SEC to delist several companies and a few others are trading at a tiny fraction of their former share price.
I'm standing by my prediction that Donald Trump will withdraw himself from the nomination prior to the Iowa primaries (and it will take these poll numbers continuing past Christmas for me to think otherwise) [1].

If anyone has a chance at derailing my beliefs so far, it's been Scott Adams (of Dilbert) and his ongoing series of blogs posts about the 'Master Wizard Hypothesis' [2]. He's essentially arguing that linguistic wizardry can trump (sorry) policy and credibility, and that the Donald is a master. Likely for entertainment purposes only, but he's been right on this matter more than Nate Silver so far! Every time you see 'low energy' Bush, 'nice guy' Carson, or 'that face' Fiorina in the press, Adams makes more sense.

I've seen a website without password. To login: you have to fill you email adress, they send you an email with a one time auto login token.

It was great!

But (because, there is a "but") it was (I repeat) a one time auto login token.

If there was a for ever auto login token, this mail may be lost, duplicate, or worse, compromised.

The one time auto login is "secured" in the way you know you will have first access to this mail (mail is mostly unsafe) and the link worked.

Advantage : only one password (double authenticated for several providers) for your mail.
As would be an oauth connection.

In a transactional mail ? Muh... "transactional" mean with an action, but commonly with a paid action, with private informations like a credit card number... I will not feel safe if in the same email I have a confirmation I have paid something (ie: advice about payment information are provided) and a link that allows the mail reader to get those informations.

Throw variable air intake, variable timings and injection patterns into the mix and you get powerful, clean and efficient engine. Which leads to a question whether this cheat by VW is intentional or a (possibly intelligently executed) side effect?

For a person to person transaction they say there is no limit, as long as a bill is recorded if amounts > 1500e.
