Their models just weren't that useful:

https://towardsdatascience.com/effect-of-cambridge-analytica...

> Sumpter analyzed the accuracy of Cambridge Analytica’s regression models in his book ‘Outnumbered.’ He used a publicly available dataset created by Michal Kosinski and his colleagues, a psychologist, who created an anonymized database of 20,000 Facebook users. Of the 20,000 Facebook users 19,742 were US-based, and of that amount 4,744 had registered their preferred political party Democratic or Republican, and had also liked over 50 Facebook pages. Sumpter first aimed to test the accuracy of regression models in general, and so created a model which predicted political party allegiance based on Facebook page likes. He concluded that the regression model worked “very well for hardcore Democrats and Republicans” but “does not reveal anything about the 76 percent of users who did not put their political allegiance on Facebook” (Sumpter, pg. 52–53). He also describes how just because the model may have revealed, for instance, that Democrats tend to like Harry Potter, it does not necessarily mean that other Harry Potter fans like Democrats. Therefore, a strategy employed by Democrats to aim to get Harry Potter fans to vote, may not necessarily benefit them.

You'd probably have better spent your money by using party-owned voter databases to create custom audiences based on email addresses. Everything I've seen points to Cambridge Analytica being mainly an operation to grift campaign dollars. From the same article:

> CEO Alexander Nix himself corroborates these results. He claimed in his testimony to members of the British parliament’s ‘Digital, Culture, Media and Sport committee,’. He contended that Kogan’s dataset wasn’t very useful and that made up a tiny part of their overall strategy for the 2016 United States presidential election. How do we resonate this admission, with his presentation at the Concordia summit, in which Nix openly bragged about the ability to wield Facebook data to tune an incredibly powerful instrument that significantly impacts elections? The answer to that came from Nix himself in his testimony, claiming that he has in the past used hyperbole when pitching his company to potential clients. This view is corroborated by Kogan who mentions how “Nix is trying to promote (the personality algorithm) because he has a strong financial incentive to tell a story about how Cambridge Analytica have a secret weapon” (Sumpter, pg. 54).
Thanks for this, Debbie Downer. This was all I needed to brighten my day.
It's amazing how all of this was based on personal credibility, and a single Tweet caused the death spiral to start.

Wells Fargo isn't going to go out of business if the CEO of Bank of America insults it on Twitter. But even if it did, there is FDIC insurance for deposits, and nobody whose balances were under the insurance limits will lose a penny.

FTX succeeded solely based on the reputation and personal credibility of its founder. One tweet from the CEO of a rival exchange and the whole thing came crashing down, taking a significant bite out of the value of many cryptocurrencies. So, even people who didn't have accounts at FTX are hurt by their assets losing value.
I don't write tests based on xpath or ids - it is too fragile. I just stick a special class on elements I want to target, like class="test-save-user-button". This allows changing the markup however you want without breaking tests. Just leave the test-* classes alone and you're fine.
And the people in the housing bubble mostly lived in those houses, yet they got burned by the crisis nonetheless.

You don't properly evaluate the present value of money if you are willing to trade your present money for future money at completely unknown conversion rate and adoption date.

Relative to the strategy of buying it when you could use it (which also satisfies your intents) you are practically speculating. You can also look at it like opportunity cost.

Sorry, my fault for combining sentences! it was 80% of the amber alerts they studied.

"Presumably because of that need "to make an intuitive, rapid decision," as Griffin puts it, AMBER Alerts often turn out to be false alarms. Of the alerts the UNR team tracked, about 20 percent involved a kidnapping by a stranger or slight acquaintance of the child.

In the other 80 percent of cases, the youngsters were taken by a relative (most often a parent) or an acquaintance (frequently a babysitter). While such incidents can be traumatic to both the child and the custodial parent, they are routinely resolved peacefully."

Playwright does use "real" web browsers (Chromium, Firefox, WebKit). It just supports specific versions, as otherwise it would be difficult to maintain. It runs them in headless mode, which most browsers support, and should behave exactly as a headed version would. You can start a test in headed mode if you want to see the browser window.

The era of custom headless browsers like PhantomJS, or Selenium/WebDriver for that matter, is dead, IMO. The Chrome DevTools Protocol is the modern standard API to interact with a browser programmatically.
what I find strange is that selling ads makes more money than selling service. Because at the end the people watching the ads are buying the stuff advertised so those who adverstise have more money for advertising….
So for it to be rentable people have to buy way more than the ad revenue google makes. If spending for google ads is 1% of bussines budget and budget has to be at least Revenue……..with 280 billion revenue for google it would be 280.000.000.000.000 that we as humans have to spend for stuff that was advertised on google so someone pays google for ads so they can run google search etc ….

35 dollar is maybe ok… …. Maybe better than spending 3500$ on … I dont know … stuff is good also ..
I think this is part of the point.

I'd love to see the tech behind this get open sourced, so GitLab and whoever else can adopt it as a standard.
Your criticisms aren't the primary problem against solar.

Fender bender? I had a lady back into my challenger, plain unpainted black plastic was $3000. Sure I didn't pay... but in terms of solar panel. Cant be worse.

Dirty? An actual excuse to wash your car for legitimate benefit? In terms of power production if not, should be fairly minimal reduction with exception of bad conditions like winter.

The actual reason why its bad and elon musk talked about it. Jehu garcia has a good video. omg 8 year old video: https://www.youtube.com/watch?v=Kg_7rJs8hLs

Basically the power you can harvest isn't much. Even with the large flat roof of the samba. flipside, bad because the flat nose of the samba.

But lets say it works for you. you drive 2km to work and park in a sunny parking lot all day. It's not just expensive solar panels. It's the charge controller, it's the battery bms, its all these things you need to upgrade. These aren't trivial upgrades. The cost to integrate into a controller system like a tesla would double or triple the cost. solid state AC controllers are really expensive to beginwith. So in order to integrate solar into a tesla with their high power. It doesnt make sense. Take the money and put it in more battery or just charge off the cheap grid.

Flipside. Aptera did something slightly different. They are tremendously lightweight and aerodynamic. It lets them have low power to high performance. So in effect they have an equivalency to tesla in terms of power, but solar is handled.

What OP did was different since its not aerodynamic nor lightweight. They are VERY low powered. Their 0-60 times requires a calendar, not a stop watch.

Worse yet, there's not much you can really change here. There's no major breakthrough in technology which really changes this. There's really just not that much power even if you had 100% efficient solar panels. The solar state controllers are practically unimprovable, maybe room temp super conductors will help?

Interesting. What are they using to run the VM on Linux? QEMU? I looked through the article but didn't see that part explained.
crypto *is* traditional finance. whenever humans transact with each other, we reify the behavioral mechanisms which define us as a species. we cannot help but create economies, to trade and transact. all finance is "traditional" finance until our biology changes and new emergent dynamics and equilibriums establish themselves. however thermodynamics, statistics and other math might also have a lot to say on the matter.

there is no such thing as traditional finance, just finance.
What would it mean to crash "for good"?

The network will never go offline because it's decentralized and costs nothing to run a node (miners are different).

Someone will always be willing to pay a few cents or dollars for one.

The best you can get is "stable," which then makes it attractive as a store of value again, and ramps back up the demand.

It will never end.
Thanks for posting the interview with Shadi Saleh. I found it interesting they were able to mitigate sanctions by using FOSS software. I wish Saleh had gone into more depth on the hardware side of things which I imagine is also complicated by sanctions.
Ask HN: Camera off during most of the meetings?
For the ones who work remotely and interact via video calls: what’s your experience? I find that most often than not:

- camera off during daily standups. Most of the team (if not all) do not turn on the camera “just” for the standup. I kinda like it (because I wake up like 15 min before, so not my best face)

- for 1 on 1s, camera always on. Haven’t found anyone yet who does 1 on 1 with camera off

- for team meetings that deal with grooming, technical discussions, planning, retrospectives, etc.: usually off. Maybe 20% of the time, someone turns on the camera. But 100% of the time there’s always someone not turning it on

- for meetings with other teams: there’s always more people with camera on (around 90%)

- all hands meeting: majority with camera off

- socializing video calls: camera on (it’s a non mandatory session, so the ones who attend do so properly)

I have worked with people mainly from Europe, Middle East, and Africa. Zero experience with people from Asia and America.

And my answer is that you don't. If you want content moderation (via a judge upholding the law, or a registrar admin who would prevent squatting) then use a stack that respects those authorities. If you chose to participate in one that doesn't, then you don't get those protections. Engineering is full of trade-offs.

Well if they're paying (in terms of the use of their hardware, electricity, and internet connection) to keep the distributed service running so that they can use it, then presumably they trust its author (and its dependencies) to some degree, right? Otherwise they wouldn't want to use it. Trust is a necessary ingredient to most cool things, and as long as it's explicit trust I got no problem with it.

People trust that folding@home or bitcoin mining is not going to open their network up to attack or some other malicious thing, so I don't see how this would be any different.

The question is not do they trust me (an author of a dependency of the service that they want to use). That happens all the time. The question is can that service's author offload "hosting" to the users without requiring that they trust each other?

For certain very restrictive applications, the answer is clearly yes. IPFS users host each others' content all the time. But can "hosting" here be safely expanded to a wider and more useful set of actions? Because if it is, I think that at the very least we could all deal with less downtime, pay less for remote compute, and see fewer ads.
What decentralised asset?
Hahah now I can use my phone as a hand warmer this winter.
It's incredible that this is an app!
Yeah. Bitcoin is on a four year cycle due to the supply cutting in half every four years. Look at 2014, 2018, and now 2022, they are all pretty similar. I think it may still drop a bit further before all is said and done.

I am expecting the recovery to begin next year leading into the 2024 halving, but we will see.
creating 20,000 new currencies isnt really an economy, or rather its a purely entertainment based economy like Las Vegas or Macau. Those things I guess are valuable but is this the best use of our computing power and our Human Resources?

Hey, if you want to really get into it, a brick is made of physical materials that took time and a process to form into a brick, and has practical as well as decorative uses.

Yeah, but instead of "meh, I'll wash the car tomorrow" and just drive a dirty car, you get diminished range.

And if you're in an area prone to drought (like places that get plenty of sun), washing your car may not even be feasible.
If a large enough user base and set of vendors accept crypto, there's no need for converting to USD.

How do you handle refunds? Converting twice? Sure, charge users for it, you'll be driven out of the market by businesses who are not scared to keep a crypto wallet liquid.
In controlled environments, praying mantis females ate the male after getting impregnated a lot of the time! BUT, turns out the stress of the lab environment was causing this and happens far less in nature. I wonder if this chucking-of-things is similar, where the octupuses are unnaturally close.

I highly recommend one of my favorite documentaries of all time, My Octupus Teacher. Dude straight up befriends an octopus and documents her life.
The car this article is about gets 10-20 miles a day.

Also "optimal sun conditions" obviously means keeping your car in direct sunlight the entire day. That rules out putting your car in a garage, which consequently rules out most urban use where short distances would be sufficient for most use.
That's totally understandable but it doesn't take the expertise of a marketing team to notice the problems here. Just think whether you personally would like to find out about some neat new feature of a tool you use through some weird janky scrolljacking page which then takes you to a waitlist. And then something about a video presentation and a pinky promise the waitlist is short. I'm guessing you probably don't, like most people. A 0.1 of an open source project can have a lot of rough edges but doesn't have any of this ceremony.
My car spends the majority of its life in a covered parking structure. Solar on roofs (as sibling comment also suggested) probably makes more sense in the vast majority of cases.
Homebrew handles this kinda poorly, so people are often confused. `brew install docker` installs the Docker CLI. `brew install --cask docker` installs Docker Desktop, and if you've permanently tapped homebrew-cask you'll get that instead of the Docker CLI.
Starting a WHPX-accelerated VM with QEMU on Windows takes less than 15 seconds with a minimal init. Is Hyper-V really that much slower?
Giving all my passwords, bookmarks and possibly browser history and credit card information to a closed source browser from an unknown company sounds too risky for me. How do they even plan to make money?
I'm with you; I'm a paid Kagi user for a while now, and unlike various attempts at switching to duck duck go (et al), Kagi is actually fully working for me. I do not switch back to Google more than once a month, and each time I've gotten "worse" results so far.

I'm sold, literally.
Counterpoint: Stanley Druckenmiller, who many, including myself, think is the most successful investor/trader alive (something like 30% a year average for 30 years with not a single down year) is on the record saying that during recessions he makes money by buying bonds.
Oh, OK! I misunderstood the comment entirely then. Thanks for correcting me there, especially since I was apparently too lazy to look for myself.

This does sound more promising then, if they've found new ways to add maintainability or QoL aspects to record/replay. As I said elsewhere, I think r/r gets a bad rap, and those sorts of improvements would increase the number of situations where it makes sense (at least for testing in incubation).
It's just nicer to work with.

I'm pretty sure they have equivalent (or very close to that) functionality, in that anything you can do in Playwright can be expressed in Selenium and vice-versa.

But Playwright, from my experience, is much easier to use. The documentation is more comprehensive, and the API design is much more aligned with the kind of things I want to get done.

This is because Playwright has benefited from decades of experience in the space which started with Selenium. The engineers behind Playwright previously built Puppeteer, which was itself an evolution of ideas from Selenium.
It sounds like easy money, but the volatility will likely liquidate you if you use any kind of leverage, and there are also lending fees you would likely have to pay. I would be happy to take you up on that bet though. I would be very surprised if it even drops below $10k again.
Kurt Vonnegut at 100
I like the idea. Maybe a 'Search for me' button instead of the current 'I'm feeling lucky'. Or two columns or tabs for personalised and general results. Sounds easy, but I am not aware of any search engines that offer this, unfortunately.

On the other hand, a lot of the search results bias stems from the search query itself. "Does X cause Y" for example will show results that echo the search, and not show opposite results. Simply because you did not ask the opposite or a more open/unbiased query like "X Y".
100% this. I skimmed the site and no mention of open source, let alone an intent of making it an open standard.

Openness makes all the difference. Hard pass.

To be clear, Rust has this exact same functionality, with an intrinsic as well as a regular function that wraps said intrinsic.

The only difference is that it’s marked unsafe.

This is the right answer. If you short crypto through crypto platforms, you take too much counterparty risk. This lets you avoid it, though it only works for Bitcoin.
What's wrong with social media?

It's not boring enough.

Just go out in the real world to buy some groceries and you'll see how boring and mundane the whole experience is.

Big social media platforms are populated by 3B people so they should represent a similar experience, but NO! The content presented to you is not randomly picked from a sample of 3B, so you don't get in your feed a random Indian guy wishing happy birthday to his random grandma.

You get non-random content. Now the reason why you get non-random content is a bit contentious.

People who love to critique social media companies would say they have an hand in that and operate out of bad faith to optimize engagement, people who want to give them the benefit of the doubt would argue that humans are wired to pay particular attention to verbal fights, proper fights, train wrecks, bad news, drama and incendiary content in general. So in the latter case each and everyone of us trained the algorithm to show us incendiary content by paying attention to incendiary content in the past.

Maybe truth is in the middle.
They imagine they're buying into a company that will start paying dividends once it stops seeing further areas of massive growth.

But for right now, they're quite content for Amazon to be e.g. reinvesting its profit into things like its own last-mile delivery service, for starters.

Once Amazon becomes more popular than UPS, Kroger, Walgreens, and probably five other companies in their respective markets, then it'll be time to open the dividends tap. But that doing it now would be throwing away money, sacrificing future profit for present.

I'm not saying I do or don't think Amazon is going to succeed in these things, but I do think that is absolutely what people invested in Amazon believe they're buying.
The question in my mind with Binance is how reliant they are on BTC. The non-BNB part of their SAFU (a pair of wallets they call an emergency insurance fund) is roughly half BTC, the other half being BUSD which I wouldn't 100% trust if Binance was in trouble. Could they survive a FTX-style panic if BTC had dropped below $10k? I hope so, at least.
