European cities have much worse air pollution than American ones because they went with diesels instead of hybrids in an attempt to be more green and partly because of German auto lobbying.
It will be interesting to see how much uptake such a top-level index gets.

The search capability (e.g., https://news.ycombinator.com/item?id=10264811) returns so many results for typical naive queries ("temperature" returns 8300), that it's impossible to sift through them. They seem to be un-curated, so a niche product with marginal calibration gets equal play to flagship products with thousands of users.

People like me who use lots of this data every day have sat in panels and workshops and mused whether a searchable top-level index would be useful, because this is not how scientists work. They ask their friends which sources are best for their use, e.g., which have the right coverage and sampling in space, time, and wavelength. And they settle into something, and maybe make a big shift to a new product when it comes online.

But: something like this index could be helpful, to citizens, decision-makers (e.g., tree canopy depth maps for fighting forest fires), and to out-of-discipline scientists ("what if I brought in NASA sea surface temperature to my analysis of beach restaurant revenue fluctuations?").

For CO2, here's an example (https://co2.jpl.nasa.gov) which gives 5 simple use cases and sketches why you'd choose one over the other.
In order to argue that, wouldn't they have to show that they authored the song well before 1911, but didn't publish it, and that somebody else somehow found their unpublished song and stole it? Because otherwise, it sounds like the 1911 "Happy Birthday" is either an independent creation or else they took the song from the 1911 author.
Karma is the worst known proxy to expectations of reasonable behavior, except for all other proxies that have been tried.

It's basically a linear prediction model: someone who behaved reasonably in the past is expected to continue doing so. This is not always true, of course, but I beg anyone suggest a more precise model that can be realistically implemented.

Another purpose of karma is preventing a bot from registering 1000 accounts and using them immediatley for insistent mass downvoting. Of course, one can build rings of bot accounts that upvote each other to gain karma before operation, but this takes much more determination and skill than an internet hooligan usually possesses.

Two things;

The big HUGE win for lua in this, in my view, is the plethora of packages on luarocks. With simple scripts, as presented in this blog posts, sure a javascript subset is fine. But suppose you want to interact with redis from your script? Where's the c ffi interface, and a prepared package you can use from nginscript? Grap hiredis bindings from luarocks, and your set.

Second, great yet another javascript implementation. They're very open about supporting a subset out of the gate, who knows how long it would take to reach parity with es 5 or 6 even?
The "Lenovo.TVT.CustomerFeedback.Agent.exe" that this article labels as spyware is explained on lenovo's website below. Did the author bother using google? The program reports if you are using lenovo's apps for usage statistics.

"Some applications in the preload collect usage data that is transmitted to Lenovo. This includes statistics about which features/settings are being used and how often they are being used. The data does not include any personally identifiable information (PII). Lenovo uses this information to improve our applications and focus on the features that are being used the most."

For some reason, this company on my list remains a hated

I don't hate it, in fact I recommend my friends try it, I have honestly tried to use one myself for 3 years but two things would always trip me:

1.) cmd/fn is swapped on their small keyboards and

2.) alt-tab requires you to think. Last app? Last document?

Furthermore there are lots of smaller issues like shortcuts: that there was no consistent way to mark to the start / end of the current line (at least three years ago).

The price is kinda ok, my biggest complaint about the mac is the lack of attention to things that actually matters to me: sane, consistent keyboard layout (or an option to swap, I don't look at the keys to much so I don't care about the label as long as it works) and not breaking the most basic workflows.

> You seem to imagine that the public overwhelmingly opposes surveillance but politicians are simply ignoring its wishes.

Not so! I think that the number of people who care about surveillance is small, and the number willing to change their vote because of it is microscopic. But, you know what? Nobody said lobbying for political change is easy.

> If you could find the votes to enact such a strategy in a way that politicians would understand they were being punished for surveillance and not just subject to the irrationality of the American people like they always are, wouldn't it be much simpler to rally those people around support for a candidate that will actually dismantle the national security apparatus?

It would be simpler, but it would be less likely to succeed. Even if you find such a candidate, and even if they were sincere in their promises, they're still likely to end up steamrollered by all the other politicians who don't meet those standards. If you change the incentives, though, you've changed the entire system and now all the insincere politicians -- which is 95% of them -- are on your side. Victory will inevitably follow.
I'm still a bit confused about how right-to-download helps non-nerds. I think I have a minor allergic reaction to things that are (a) so hard to implement that they raise barriers to newcomers and (b) only help the nerd class.
My understanding is that diesel cars had to be manufactured with either a NOx storage catalyst or injectable urea, both designed to convert the NOx emissions into something less harmful. What VM did seems to be the equivalent of just removing the catalytic converter.

It beggars belief that the ceo and many executives were unaware. Considering that, in order to make emissions standards, competitors have to add hardware to the emissions system or inject urea, which increases costs and hassle to the driver (you have to fill the AdBlue, every piece of hardware is a maintenance cost waiting to happen) and to VW (plumbing, harder to convince drivers to buy diesel.) VW figured out a way to avoid both, a distinct advantage to their diesel products. And nobody in the executive team inquired at all how this engineering miracle they pulled off worked? I don't believe it. If nothing else, someone in the executive team asked how long it would take their competitors to copy VW's innovation. Or suggested patenting it.

Do you really honestly believe that they "accidentally" implemented a feature to associate with open wifi networks, grab any and all data they could, and store that data in their archive?

Google is a big place. One or more people designed that feature, multiple people implemented it, probably dozens of others tested it, and managers signed off on it before it was deployed on their StreetView cars.

It's not like "Whoops, someone left out a null check and it accidentally grabbed all your data!"

I know that there are some great projects related to neural networks. But they are focused on deep neural networks. Apart from this trend in neural networks there are many other great ideas like Autoassociative memories, learning base on associations, Adaptive resonance theory and so on. They are really cool and you can make a lot of interesting projects with them. This was a major inspiration for this library.
> Are diesel vehicles actually more environmentally friendly?

Yes (legal) diesel passenger vehicles and light trucks sold in the US since [edit: 2007] are significantly cleaner in all respects than their gasoline equivalents, although that difference goes away soon as the gas regulations catch up.

It's very unlikely you could detect whether the vehicle in front of you is gas or diesel just by looking at it or smelling the exhaust.

That said, there are a lot of pre-2005s out there, showing smoke and smelling bad. Also the heavy trucks are just now getting the emissions requirements that lighter vehicles have had for the last 10 years.

I have a 2012 heavy-duty diesel pickup. Except for the logo on it and maybe the sound of the engine, you'd never know it was diesel.
Exactly, it is using bpf_probe_read. Internally, BCC uses clang's Rewriter functionality to mangle valid C (but invalid BPF) into valid C with bpf helper functions.

The req->rq_disk->disk_name expression would expand into:

({ typeof(char [32]) _val; memset(&_val, 0, sizeof(_val)); bpf_probe_read(&_val, sizeof(_val), (u64)({ typeof(struct gendisk *) _val; memset(&_val, 0, sizeof(_val)); bpf_probe_read(&_val, sizeof(_val), (u64)req + offsetof(struct request, rq_disk)); _val; }) + offsetof(struct gendisk, disk_name)); _val; }));

If you are playing with the tools, the BPF() class takes an optional argument debug=, where bit 2 (0x4) will print the rewritten C output for your edification.
I don't know if it directly answers your question, but NOx emissions are dependent on combustion temperature I believe, so the ECU could potentially adjust fuel and timings to create conditions that don't spew NOx, but don't perform as well either. Then when on the road, it opens back up to increase performance but liberate more of the NOx that otherwise might be bound up in less harmful substances or caught by the particulate filter/catalytic converter.
May it go to zero. If the penalties get high enough, I could see bankruptcy wiping out shareholders.

The sulfur content of the diesel is the primary driver of particulate emissions.

> The impact of diesel fuel sulfur reduction on directly-emitted and secondary atmospheric particulate is evaluated by experiment and analysis. Experimental evidence shows that fuel sulfur conversion rate to particulate sulfate is linear down to zero sulfur level.

> Analysis shows that sulfur-derived particulate accounts for the vast majority of atmospheric particulate from diesel engines. Consequently, fuel sulfur reduction would have a far greater impact in reducing atmospheric particulate burden than any other diesel engine particulate control strategy.

Sorry, this one's paywalled, but it's a finding that has been repeatedly reproduced in the literature.

I completely agree about biodiesel. ULSD is a big step forward but biodiesel is even better in terms of emissions profile. It's also got a number of other things going for it - it can be run in conventional un-modified diesel engines that don't produce high-tech waste, and there's several factors that make its production more desirable than other biofuels.
The problem is that people make up all sorts of ridiculous "laws" in their heads, and get extremely self-righteous when those invented, nonsensical rules are violated. Email service providers are exceedingly conservative, and will nearly always side with these people, even if they're lunatics.

For example: sending someone an unsolicited email is not spam. If it were, then nearly every person with an email account would be guilty of bulk spamming. Yet many people have no hesitation about clicking the spam button when they get a message from someone they don't know. Email providers are so scared of this that many officially require double-opt-in procedures in order to open an account. That's insane.

I don't mind it when someone emails me, personally, one time with an unsolicited business offer that is specific to me. It's unambiguously legal, and it's a good thing that we can send each other messages without having to pre-authorize the message. But when people send me the "follow up" on their last unsolicited message? Then they get the spam button and a block.
> The losers are small publishers and small advertisers. Universal click fraud drives down the value of all advertising, making it harder for niche publishers to make ends meet.

This is absolutely not true in my case. I'm both a small publisher and a small advertiser. I have absolutely no trouble making ends meet. Perhaps I will in the future, but it is very unlikely that click fraud or or privacy concerns will be to blame.
So, serious question, but your solution to people paying to avoid advertising is to circumvent it anyway? Are you surprised when your click-thru rates are abysmal?
The researchers also tested a diesel BMW X5, which passed emissions tests. [0]

I would guess that its just more expensive to implement, more steps in the filtration process, larger catalytic converters, etc.

I will be amazed if true! Last time I looked at the emscripten-Rust stack it was a tower of hacks and required a custom-hacked standard library. If that's all abstracted behind cargo build scripts that's awesome, but we're still a ways from having this be elegantly integrated into the Rust system.

It's going to improve rapidly though.

Ask HN: How do you deal with multitasking overload
I've noticed recently that way too often I will open a program to do something and then notice something that I was doing earlier, finish it or work on it for a while, then finally go back to the original app, remember what I was supposed to be doing and go back to it.

Does anybody else have this problem? I find myself getting caught up in this loop all the time.

Ironically, this is an instance of that, I'll probably get distracted by some article after I submit this and not go back to what I was doing.
I had read something about how diesel engines can use Urea to trap emissions, but it must be refilled frequently, so possibly other manufacturers are using that method. This is tested and proved to work well. However, VW was using another type of method to diminish emissions that has not been well proven. Source: a comment I read on Reddit, so take it with a grain of salt.

Edit: found at least one source on how this works: http://www.greencarreports.com/news/1042727_adding-urea-to-c...
That may be, but inflated pricing on eBooks will put the publishers in the boat as the music industry. By your logic, there should not be any 99 cent MP3 files. They should all be priced as though they were 12 inch singles.

Files are files. Sell me something physical and it had to be created. Files? Nope.

eBooks are still being price fixed. Plain and simple. Even Baen admits to raising their eBook prices to match other vendors, even though they've capped theirs based on their own hardcopy prices. Whether there is collusion or not I wouldn't venture a guess. Before Mr. Baen died, I would say no.
