What makes electric cars viable isn't that batteries have anywhere near the energy density of gasoline, it's that if you use them, you get to replace half a ton of engine, transmission, alternator, fuel pump, emissions and exhaust with a <100 pound electric motor, and have that cost and weight budget to use for batteries instead.

This naturally makes battery improvements a huge win. If you double power density you can cut the weight of the battery by more than half for the same range, since not only do you get the same power from a lighter battery, now the car is lighter and requires less energy to accelerate.

What I am saying is that the reason the cost can be bigger even if there were less extreme weather is that we have more stuff and we build places we didn't before. We have more stuff to be destroyed.

You would have so show the same amount of stuff, extreme weather and that this extreme weather is because of climate change to make a case for this to be climate related.

It's the usual sloppy catastrophic thinking that we unfortunately see in this highly policial debate.

If the data you're referring to didn't come from a company like CA, how did the campaign get access to it?
Is FB making their raw data public, though?

There's a strategy/tactics divide to consider. Relying on FB's targeting algorithms is tactical - that'll give you great targeting once the time comes to execute your campaign.

But CA data, even if noisy, has been exfiltrated out from under privacy controls, so that you can get a much more direct look at it. That allows an analyst to get a more detailed sense of what social networks actually look like. I imagine that is more useful for figuring out what kinds of people you should be targeting in the first place, in order to maximize the leverage of your campaign.

That makes it sound rather nefarious. Rather than the experience motivating a book, it reduces it to a muckraker looking for drama. Non-fiction p-hacking.

C'mon, Google is an ad platform. Everything Google does that isn't selling ads is a rounding error next to the ads.

At least newspapers and magazines have subscribers that pay directly for the content. In fact, since Google and Facebook have eaten their advertising lunch, legacy publishers are more dependent on subscription revenue: https://medium.com/the-graph/advertising-vs-subscription-a42...

I love the idea of figuring out how we can stop reinventing the wheel. Too much of this work really has no benefit to society yet keeps getting done, over and over. I wish for a way to pull the brakes and re-evaluate what it is that we are all doing exactly, and for whose benefit.
You can get cheap 1 Gbps wired Internet in France, yet, in the 5 cities I've lived since 2016:
- I actually have > 100 Mbps in 2 of them (both in the 20 biggest cities);
- I painfully had > 5 Mbps in 1 of them (in the 20 biggest cities)
- I painfully have > 500 kbps in 2 of them (much smaller cities, but still in big urban areas).

I assume France is in the developed world as of 2020 and I believe I've more luck wrt Internet than most people here.
Given that I'm running fiber that connects to the local university backbone, I'm running the fastest possible link in my area (excepting those in the university).

I wouldn't bet on the industry reforming itself. If all other industries are an indication, quality and safety needs to be regulated in.

Boeing case is indeed good example. They cared about safety of their planes up until they figured out how to make more money by skillfully avoiding having to care. It looks like it blew up in their faces, but I'm not so sure of that - they're more than "too big to fail", they're a strategic company for the US, so the military won't let them fail.

> If we put in the effort to make something a little easier, safer and faster that people use every day, you impact more lifes than you might know.

My point (here and in parallel reply) is, if "being a professional" is defined as being focused on business objectives and bringing in revenue through your work, then putting in that effort, making things easier, safer and faster, are all - by that definition - unprofessional behavior. Sacrificing time and revenue for goals the market doesn't care about.
Sometimes people reinvent the wheel simply because they need a new project to take credit for. Every link in the chain needs an accomplishment to point toward when justifying themselves to superiors.
There are also social cues and the lack of an ever present mob. A lot of people who are political activists online are not actually that confident in their views and absent the audience and ready defenders, won't express their views because they know they can't back it up in a one-on-one conversation.

Our city did a traffic survey of a local street that is the primary route for everyone going from surrounding neighborhoods to downtown and found the average speed was ~2 mph over the posted limit, with the 85th percentile at ~5 mph over the speed limit. These are reasonable speed for such a wide road. The city then added several 'safety' features to it, and found in a subsequent survey that the changes actually did little to slow traffic. One feature is a pair of speed bumps. Some drivers slow to about 5 mph to go over the bumps, increasing the risk of rear end accidents. Other drivers veer into the bike lanes to go partially around them without slowing down. Everyone else slows down a reasonable amount, but then subsequently accelerate back up to the speed limit on a block where jaywalking is common. Some of the features they added are, in my opinion, beneficial, like turning a side street into a one way road after frequent accidents from people turning left out of it.

But you can't talk about it on Nextdoor. The second you criticize the speed bumps you'll be ignored (if you're lucky) or attacked. Nuance is not allowed. You're either for all the changes, even the dangerous ones, or you're a crazy speed demon. Meanwhile, if you post about 'the children' who you are afraid for (even though no one has any evidence of a child ever being hurt by a driver on this road), you're going to get upvoted a lot within the first ten minutes.

"The Metrics of Backpacks" by Victoria Gannon

https://www.artpractical.com/column/the-metrics-of-backpacks...
Downleveling happens, but the $ calculation almost always makes it out very much ahead. At my previous job at a startup, I was making $160k base with stock options as a tech lead/engineering manager, but at my current job at a FAANG, I was offered the same base but with $15k signing bonus and $105k RSUs that are now almost worth double as a high mid-level engineer. For me, accepting the offer was an absolutely a fantastic financial decision. Responsibility-wise, I never felt like I was given less responsibility than at a startup either.

What the downleveling does is align expectations correctly, since most people not at a top tier company likely need some time to ramp up to the expectations of the next level up. What senior/staff/principal mean at companies like Google/FB/Apple is very different from what it means at most companies.
Some games can be far more demanding than video streaming. HDR content, 4k, >60fps, 4:4:4 chroma (text looks horrible on 4:2:0). The requirement for realtime encoding instead offline encoding also means the codecs get less lookahead (as few frames as possible) which results in higher bandwidth requirements for a certain quality level compared to VoD.
> Every well-designed study of political advertising

Wouldn't that be misleading though? There are active disinformation campaigns that are linked to the same people and organizations doing political campaigning.

Cambridge Analytica has apparently been (at the least) tracking people via these networks [1] [2], and it's not much of a stretch to assume some of the same targeting data used for traditional political ads would also be used for disinformation (which is often designed so it doesn't appear to be political).

There are news and TV networks that constantly present confirmed lies (often stated by the politicians themselves) as "news", so the fact they still have viewers and are still in business must mean this type of disinformation is somewhere between somewhat and extremely effective. Whether this is "political advertising" is maybe less clear, but it's definitely designed to influence politics and political opinions.

Most importantly of all, a stagnating economy is likely the only way anyone in the Democratic primary can beat Trump. And there's not an editor in the country who isn't carefully weighing this when picking what finance stories to run.
Voter registration information is public, also both parties have huge, manually curated lists that they sell access to. But giving FB a seed audience of 10000 voters and asking them to find the 100mil most similar people works better a lot of the time. The effectiveness of FB's machine learning on this stuff would blow your mind.
They use it in games like thumper. Also, this same technique is already used in many street fighter style fighting games. Its not new - and it works.
I agree with you 100% and have to say that the replies on this particular thread are some of the most toxic I’ve ever read here on HN, and completely indicative of both what you describe as well as my own observations from living here in the Bay for pretty much my entire life.

I live in the South Bay, don’t work in tech, make well under $100k a year, live comfortably and have had no issues dating. I’m a local, white and over six feet tall, so that probably helps, but I’m certainly nothing special looks wise.

It's not interesting to talk about a system that might or might not exist in the future. (There is a word for that—"vaporware".) The point is that Zig doesn't even try to prevent UAF now, so you can't say that it's safer than languages that do prevent the problem.

Hasn't this essentially been what C++ has been trying for memory safety for decades, without success? The C++ approach has been "smart pointers are good enough, and they prevent several other problems too", and the experience of web browsers (among others) has pretty much definitively shown: no, they really aren't. For memory safety, I would not bet on this approach.

> How about American business magnate and billionaire playboy

American is redundant. It is _literally_ a requirement of the office that you be an American. You might remember this because Trump spent almost a decade pretending to believe his predecessor wasn't American. Countries which are more confident don't have such a rule but the American Founding Fathers feared a European power might try to seize control.

Magnate just means wealthy or powerful man so it is also redundant with your other qualifications.

Billionaire is based on Trump's claims, he has gone out of his way to ensure nobody actually knows what he's worth. One of the dirty secrets about "rich lists" is that all the interesting people on them don't have verifiable wealth so the list makers invariably resort to guesswork or fiction.

So that leaves "playboy". My dictionary explains that a playboy is single and devotes their life to pleasure, typically sexual pleasure. But Trump is on his third wife and his main pleasure appears to be either golf or soaking up praise from other people.

> Probably the most useful takeaway from CA's approach is that it's useful to realize how malleable opinions are of large swaths of "independent" voters.

What makes you think that people are malleable? This article doesn't say anything about the effectiveness of what CA did. It's impossible to say if people voted the way they did because of a FB ad. My >20 years of experience in the consumer technology (ad) industry tells me that ads had little to no impact.

> Not enough to flip people's opinions 180 degrees, but enough to, say, get a reality TV star elected over a politician with a checkered history (that has itself been subject to decades of effort and millions spent to make said history checkered).

Clinton vs Trump wasn't an option people were waying. No one switched from Clinton to Trump (or vice versa) because of an ad or anything else. Those that hate Clinton voted for Trump, those that hate Trump voted for Clinton. It's really is as simple as that.

Have you ever met or even heard of someone who supported one of those candidates but switched to the other? I haven't.

Ask HN: How should I take advantage of unlimited PTO?
I'll be starting at a company soon that has an unlimited PTO policy. For context, this is a large (15k+ employee) enterprise software company that is known for having a good work-life balance.

I have seen this policy maligned often on HN ("unlimited PTO == no PTO", etc.), but from my personal observations at my internship at the company, people were able to take significant advantage of it. One of my teammates was encouraged by our manager to take a two-week vacation after we finished a release cycle that he'd put a lot of extra effort into.

For devs who work with (and like) unlimited PTO: what are the advantages? How have you utilized it, or how do you regret not using it sooner?

For managers with employees in this system: When (if ever) have you felt like you were being taken advantage of? Do you like or dislike the system, both for yourself and for your team(s)?

I'd like to make fairly frequent use of PTO, as I believe strongly in having a life outside of work and in mental recuperation, but I also really don't want to seem like a slacker. Any thoughts would be appreciated. (Aside from "go work somewhere with 4 weeks vacation" -- I'm quite excited about this job!)

For small teams, this goes to the weekly leadership mtg and VP's 1-1s: CEO/cto or vp eng/prod should be reporting their side, but also asking sales+marketing if they need enablement.

For next scales, two models I like are "Tiger teams" (top dev team who can jump onto stuff for pushing a VP Sales picked acct through) and dedicated analysts+devs. I'm skeptical of say A/B testing until you are huge, but stuff like sales/success/marketing automation can hit way earlier.

Among left-leaning circles there is an overwhelming feeling that the "Overton window" has shifted way too far right -- especially on things like regulation of business. Bernie Sanders is popular specifically because he shifts that window back to the left. From a deregulatory standpoint, I'm not sure Trump is significantly worse than Clinton. He's definitely worse, but the difference is smaller than Clinton vs Sanders; they're both in the pockets of the corporate overlords.

The far-left wing of the Democratic party felt that 4 years of chaos under Trump was an acceptable tradeoff in the long-term for moving the party (and the country) to the left on the economy. So they stayed home on election day and made the race close enough for Trump to win. In the current climate, moderates are going to find themselves left out in the cold in national races -- exactly because moderates are relatively easy to pull to one side or the other via targeted campaign advertising.
Yes, the problem is latency. Which is actually not that big of a problem in some parts of the world. Also, if you have a metered connection bandwidth can become a problem.
I have tested stadia at family and I was really impressed how well it works. Personally I am not going to pay for it and will keep using my consoles, but Stadia certainly works.
Chipset doesn’t run at x16 bandwidth, it gets 4 lanes of bandwidth. At least for consumer platform, but I doubt server runs anything significant off chipset. QPI/UPI may run faster between sockets but I don’t think chipset is a full speed link by any means.

Nominally QPI/UPI but those protocols are not hugely distinct from PCIe in general. AFAIK it’s basically PCIe but encrypted, so that nobody else can replicate their chipsets (like used to happen in the old days with nForce/etc).

Also your numbers are off, easy rule of thumb is that one PCIe 3.0 lane is one GB/s of bandwidth per lane. So 3.0x16 is 16 GB/s of bandwidth.

So it just needs 8 GB/s of bandwidth to run at 4.0x4 speeds.
Nobody is being forced to purchase property governed by an HOA. If you want the freedom to choose how you maintain your property, just... live somewhere else. To be clear, I'm not advocating for these schemes (and would personally never live in such a place), but the idea that it's _unreasonable_ to have a preference is silly. People are allowed to have opinions.

The irony here is that your response violates the very same principals for which you seem to be advocating. "If you want _____, follow my instructions exactly". Hmmm....

- I am fully aware that the kinds of rules, in particular, that spurned this conversation have been (and likely continue to be) abused as a facade to hide bigoted motivations. I absolutely DO NOT condone the tactic of using "personal freedom" as a means to promote these kinds of views. That IS NOT the point I was trying to make, rather, that people often _do want_ to surround themselves with like-minded people. The social science on this is crystal clear.
>Nobody except me seems to see a problem there, despite me being able to point out specific security incidents.

This seems to apply to security in general. Security these days is doing the minimum amount needed to check some boxes that you are now secure. I suspect a lot of this is driven by incentives. There is few negatives to an individual to use bad security over good security, and the costs of good security means less of the 'good stuff' being developed which results in worse reviews and less prestige. And if people are hacked, the blame is primarily placed on the hackers with little danger to the developers and often even less danger to the company (they might have to spend 5% of the budget they saved on PR to repair their image).

I'm not sure how to fix the issue with prioritization of security. My first guess would be by changing the incentives to companies so they bear the liability in identity theft instead of the user (the very concept of identify theft is a trick to blame the end consumer instead of either the business leaking data or the business giving away money without verifying if data is accurate).
It was usually a typist's job, and you paid for the newspaper, instead of watching the interview for free on Youtube.
You're going to be down-voted to oblivion on hacker news, but I do agree with the general point that, the post you're replying to saying "'reality TV star' vs 'politician subject to decades of effort and millions spent to make said history checkered'" is needlessly political and doesn't belong on hacker news (same as your post).
