> > Data from the UK National Atmospheric Emissions Inventory indicate that particles from brake wear, tyre wear and road surface wear currently constitute 60% and 73% (by mass), respectively, of primary PM2.5 and PM10 emissions from road transport, and will become more dominant in the future.

So how much does road transport contribute overall?

EV brake less than ICE.

That's fascinating, but I'm wondering what is the practical value of detecting microsaccades? Aren't they just involuntary twitching?
Yep on a 100 million dollar budget you need to hire people to manage software delivery on your side and can never absolve end responsibility is definitely my point.

I’m not describing how the world should work, just how it does when outsourcing IT to consultancies (which can work anywhere from successfully to very unsuccessfully)
The argument is the US health care system is worse. People like to bring up wait times, but your wait time is infinite if you can't afford a specialist / non-acute care.

Do they have some other authentication mechanism instead?
Yep. Most of the small companies I've seen just use the Windows DNS servers because they need them for AD. You can set up separate DNS servers and delegate AD's domain to the domain controllers, but then you're maintaining additional DNS servers.

And besides, most of the small companies I've seen vastly prefer a Windows GUI than (e.g.) configuring bind on the command line.
So you've never heard of people espouse Mars as a "backup" for Earth...then espouse Mars as a backup for Earth? Weird.

Mars is not and at no point in the next century (likely centuries) capable of being a backup of anything for Earth. It has zero industry, difficult to exploit natural resources, and the surface and subsurface environments are completely hostile to human life. A human can only live there with significant amounts of advanced technology supporting them.

A tape drive can be a back up for a hard drive because it is only mechanically different from a hard drive. A tape drive can use the same data bus, uses the same electricity, and stores the same data as a hard drive. It's just slower and less convenient. Mars is to Earth what soap bubbles for data storage are to a hard drive. They might be able to store data but they're fantastically fragile and trying to implement the system would be a waste of time.
Because quality isn't what matters, and they can paper over it with ads, personal relationships, presentations, sponsorships.

I had a pretty good experience with Sapient once.

I suggest it probably depends a lot on the location though I would never touch Accenture or Deloitte and would only allow Bain or McKinsey to deliver on something for which they had very material experience, and never let them do actual work because they will f it up.
You are correct for point 2, but as far as 1 goes: major depressive disorder (what most people mean when they say "clinical depression") requires only two weeks of anhedonia/decreased mood plus a few more symptoms to be diagnosed: https://www.ncbi.nlm.nih.gov/books/NBK519712/table/ch3.t5/. Which is interesting, because a significant number of mental health conditions do require 6 months of ongoing symptoms e.g. generalized anxiety disorder and schizophrenia. First line treatment is cognitive behavioral therapy and an SSRI.

In the aggregate sense, it eventually netted out. But a lot of people who sold when it looked like prices were collapsing sure got a pretty decent chunk of their bank accounts "erased".
I would believe we can 'colonize' mars successfully when we can set up a pilot project, as a self-sustaining colony of people at Bir Tawil, which is considerably less expensive and difficult to send cargo to on a per-kilogram basis.

# The URL is downloaded once, cached forever, and then sourced
import "https://git.io/fAWiz"

Where is this program declaring the above content's expected SHA256 to check that the expected content is being received, and not some altered version?

Think about it. You write the program with the above #import, and at the time, it fetches a certain piece of code. You see in your cache that it's the right one.

Then you deploy the script to a fellow user. They run it, and the import fetches something different from the same URL. The script breaks. You're scratching your head: hey, it works on my machine, why not yours? Or worse: the replacement code is malicious not simply breaking. The user's files are gone or whatever.
Now tell me how expensive it's going to be to make a Mars colony that, cut off from Earth, can not only maintain all its equipment but reproduce it, so it can grow.

I highly doubt this could be done anytime soon.
I don't know if there was a realistic adaptation they could have made. What would they have done, short of simply abandoning their business and becoming a massive social network publisher earlier than the ones that ended up winning?

I think what happened is that it turned out the real value newspapers provided wasn't the expensive high-quality content, but simply the printing and distribution which used to have immense barriers to entry. The Internet shattered those barriers to entry, and it turned out that all that people wanted was to have access to some timely shared national/regional/local content and that the cheaper content would tend to win.
> There are downvotes on HN. Do they really make this community better?

For others, maybe not, but for the downvote-ees, I think that they can. There's a tendency to bridle at a downvote, but I know that, especially in my early days here, downvotes were very helpful for figuring out what posts were appropriate and welcome in this community. The downvotes were an unobtrusive way for me to get the message without a huge thread in which many people individually would have been forced to make exactly the same point.

(I do notice that, in contentious discussions, downvotes are often used to express disagreement, rather than the idea that a post is not a valuable contribution, and I think that's a shame.)
> just saying there is no evidence this is based on gender ideology

I agree with that. I think it was probably motivated by petty vindictiveness. I suspect most violence inflected by prison staff against prisoners is.
The fact that one extreme is false does not make the other extreme true.

That being said, at some point if you're cutting, or if you don't know where you're cutting, at some point you will hit bone. More money is not a panacea but neither is less.
I can’t think of many things that make it better to be on Mars with no Earth support (even if your colony’s pretty well-developed and capable) than a survivor on Earth after a disaster other than something like a dwarf-planet-sized impactor. Climate change, nuclear war, and a dinosaur-killer asteroid combined wouldn’t do it. So-called “snowball Earth” is preferable. Earth with everywhere but the poles too hot and arid for crops is preferable. Mars is very hostile. Especially if you allow for your Earth-survivors having equipment like the Martian colonists do (far cheaper to provide, redundantly and distributed and hardened and with regular up-keep and replenishment, on Earth than on Mars). I can come up with some sci-fi scenarios, too, but as far as stuff that suddenly makes Mars better to be on than Earth and could happen today, it’s basically just super-huge impactors. Which isn’t nothing, but it’s a pretty small slice of the apocalypse pie.

Standard? True, undefined. Compilers, however, happily overflow unless you tell them to catch it at run time. So, my original statement is at least half false. :)
Anthropogenic (human-caused) existential and catastrophic risk is way higher than risk from natural events (like asteroid strikes). It's unfortunate that the author misses this point.

Bioterrorism, nuclear war, totalitarian governments, and other anthropogenic risks would have a harder time spreading between planets than across just one.
Florida purposely built a broken system under Governor Rick Scott. It was engineered to make sure that as few eligible people could access it as possible. It is socially and technically engineered to make it so that people give up trying to claim the unemployment benefits they are entitled to. Florida used the system to keep their unemployment numbers artificially low coming out 2008 recession.
At least now their reputation has gone up in smoke amongst the hacker news readership.
1/10th isn't even close. In my state you were looking at 40x the volume. And you have a good point, that much more traffic is probably going to break a lot of systems.

Not to mention, even if the systems were only down for a few hours or a few days, the government agencies just don't have the manpower to process all those claims. Especially when people are working from home or not working at all.

Then you have the massive fraud. A perfect time for scammers to apply for unemployment benefits.

Remember the people who don't have computers and call their claims in via touch-tone. Those systems all crashed as well, or had busy signals for weeks.
That's absurd. They take it out of your paycheck every month, it's paid entirely from employee wages, it can't be spent on anything but unemployment, and you get benefits proportional to what you contributed. It's literally your own money that they're giving back to you that they took for the sole purpose of forcing you to save money for if you lose your job at some point. It's like if I asked to borrow a pen, then when you asked for it back pretending like it was some benevolent gift.
I’ve always felt like a moon base would be the perfect stepping stone to Mars, plus, you can sustainably mine H3!

I think going directly to Mars is going to be a heck of a lot more complicated than figuring out the quarks of space living in the Moon, even though they do not parallel 1 to 1 it would be an eye opening experience I think none the less.

Also closer to the home planet, and could serve as a sort of “to Mars” way station
That didn't get disseminated and diffused to tens of millions. If something was published they'd look for official sources or corroborating sources and or secondary evidence. If AP, EFE, UPI, Kyodo, Interfax etc all get their news from one source [Twitter] that's just laziness.

The conventional wisdom in SV is that it's really hard to fire people. It's been my experience, too. I've worked with lawyers numerous times to fire people and it was always way more complex than I wanted. The problem is there are so many protected classes and once someone is in one, in CA, it makes it hard to just fire them, unless you have documented very precisely why you are firing them. And that is very taxing on everyone.

In a badly managed mess of a project, "reputation" means never implicating the wrong person in the inevitable miss-steps.

And by "wrong person", I mean "your boss, your customer, or anyone who they are friends with".
It's a culture problem. There is a belief that the size and complexity of the project must match the size and complexity of the client. So small, nimble companies don't even get considered. The budget gets set before any evaluation of the problem is done.

You could give that $10mil to a 250 person consulting company and they'll make it happen. But that will never happen. Hell, the SOW was probably written by some at Deloitte, stuffed with whatever cross section of requirements are unique enough to make them the only vendor available that matches it. Then they will bleed the contract by putting expensive partners on it who literally do nothing but suck oxygen out of the room. That's how they get around maximum multiplier of salary regulations on government contracts.
Because it leads to harassment and harm. Which gets particularly bad when it's likely a false accusation at this point.

Earth would have to turn into a lava planet for Mars to be a better option. Antarctica is more habitable than Mars and nobody's planning to set up self-sustaining colonies there. Every technology needed to survive on Mars could be implemented far easier here no matter how bad it gets.
Exactly in order to have 15000 Einstein’s from a population of 1trillion. You need 1 trillion living above poverty. We can’t even get 1 billion out of poverty. Ha. To me colonize Mars seems like premature optimization.
yes, but that relies on knowing that the quaternions are such a cover, which is entirely non-obvious. An explanation that starts and ends with SO(3) without roaming into quaternions is necessary for intuition.
Yeah UBI could’ve fixed this.

> If you gave out a time and materials contract without clear acceptance criteria, testing requirements, and verification / support / warranty detailed, you probably shouldn’t be handling 100 million dollar budgets.

That is oh so very Deloitte...look if we took $100M from you and you didn’t get what you wanted, that’s Clearly not our fault, YOU shouldn’t have been handling that type of budget in the first place. After all there are people like us out there that will hornswoggle you, luckily you can retain us Again to deliver the original contract and you should consider a separate retainer so we can protect you from people like us in the future.

Id love to see a single instance where Deloitte admitted to fault and footed the bill for a $100M contract, care to link proof for such a claim?
Definitely cutting food. Maybe this goes back to my camping days, it was easier to carry a loaf of good bread and a chunk of cheese than a bag of sandwiches. (And a tube of mustard, must not forget). A pocket knife didn't make the cleanest of cuts, but did the job, and the food always got eaten as fast as I could cut it up and hand out the pieces. Likewise for bringing food along on a car trip.

Being able to do this prevented us from getting into the habit of traveling with junk food.

The knife for this job never had to be particularly big or sharp. I have a Victorinox and a cheap old boy scout knife that won't take an edge at all.

Oddly enough when my family traveled in Europe, we would usually rent an apartment for a week or two, and would just borrow a knife from the kitchen drawer for our daily hike. It was usually a stainless serrated knife with molded handle.

Yes we also used the corkscrew. ;-)
Venus Exploration in the New Human Spaceflight Age
I won't pretend to be an expert or even necessarily a proponent, but it's worth nothing that there are public broadcasting agencies that supposedly are independent of government other than being legally bound to certain journalistic standards.
That sounds like a good strategy: form an inner circle of peers that don't have conflict of interest (preferably not sharing the same supervisor, etc.) and being vulnerable with selective people should be helpful for fine-tuning strategy, and if not, at least generate a little social power. Previously, I had the tendency to isolate and not open up to anybody, to my own detriment.
The Last Reporter in Town Had One Big Question for His Rich Boss
A realization that came to me much later in life was that, although I am in apparently full control of which thoughts I allow to persist in my mind, I do not appear to be in full control of when memories surface. Rather, very similar to my dreaming state, it seems as though there is some process which is constantly comparing my waking events to things that occurred in my past, and trying to form a connection between them.

For the most part this is good, but of course, not all memories are created equal. Sometimes this process of forming connections reminds me of a painful event, something I'd rather not think about.

At first it was frustrating when these memories surfaced repeatedly. I'd dwell on some embarassing thing I'd done, or some painful thing a friend had said to me, which they maybe didn't realize I'd taken so hard. It was tempting to analyze these events to death, and have silent conversations with these figments, as though I could go back and phrase it differently, or change my actions, and perhaps it would have gone better.

Eventually, however, I realized that these mental tasks were not productive. The event, the "danger" had already passed. So now, whenever I realize my mind is about to go down that path, when suddenly I am reminded of a painful event, we pause, my brain and I. "Do we really need to go down this road again? We know where it leads. Let's not."

And so we don't. We reach once again into the stream of thought, allow ourselves to dwell on some happier moment, and in time, that old memory fades and we're off on a different adventure.
When talking about war, the only measure more useless and irrelevant than GDP and economic strength is toenail length.

Afghanistan is sitting at around $500/capita. Russia and the US have completely failed there despite four decades of conflict. Vietnam was about $60-70 during the tail end of the Vietnam War[1]. We know how that ended.

I'd say that maybe you could win if you abandoned traditional war tactics and just bombed indiscriminately and avoided suffering too many casualties, but, well, that was tried and failed in those wars. You also wouldn't want to try it against a country that can and will fire back.

I think the Fibonacci number page isn't a great example since it explains the middle school version in the first few lines. It only goes into depth much later.

The Excess 3 page however has a really complicated first paragraph where only about 5 words even attempts to explain what it is (a self-complementary BCD) and then again uses 2 terms that you might not know. BCD has a useful link to another article but what does self-complementary mean? I only see a mention of ones complement all the way down in the motivation. It also fails to explain how addition/subtraction work so you have to figure that out yourself.

After a good amount of reading I could understand it and why it's actually cool but by god it wasn't as easy as it could have been.

I have seen a cop order a medic to give sedative to a human that was being choked by said cops for more than 10 minutes (he was basically already dead when they injected him). Search for Tony Timpa on Youtube if you want to see the video. And they were joking while killing him. And last but not least, they all kept their jobs. All humans can be bastards.
Pretty handy, particularly ratios.

I was hoping I would learn that you could do parametric formulas to define curves, and maybe even Taylor series for curves too hard to define in closed form. Someday.
> In the USA they freak out over the idea that someone might receive more unemployment than they are entitled to,

There isn’t an infinite amount of unemployment money available. If you allow fraud to run rampant in these systems, there is less money available for those who actually need it.

Enforcing rules and regulations is a good thing for everyone.

Furthermore, many people are earning more on the current USA unemployment system than they did from their original jobs. The system was designed to overpay some people for the sake of quickly delivering the system. (Source: https://fivethirtyeight.com/features/many-americans-are-gett... )
There is a treaty prohibiting antarctic colonies that expires soon. We'll see then.
Zoologist Matthew Cobb who studies modeling maggot neural systems, has just published a book "The Idea of the Brain" about the different conceptual models we have had for the brain through time. He talks about the limitations with he chemical based, neural transmitter model. That there is no drug that can be guaranteed to cure a mental illness, and that most of the large pharmaceutical research companies have withdrawn from developing new drugs in this area. And perhaps it was these companies that popularized the notion of "chemical imbalance" in the first place.

It's not true that consulting companies pay the least. They're not paying like the FAANGs or unicorns but they're higher than working for industry. As an example, at my level I can make ~200k as a consultant but only 150ish as a direct employee. It's crazy because they're willing to pay ~400k for me as a contractor.
