dpq··on Brave Search replaces Google as default search engine in the Brave browser
I think they stopped doing it long time ago (and I cannot see these links now), but if my memory serves me well basically these links were taking you to Google and Bing with the same query, respectively. I.e. they were directly linking to competitors, just in case your original search at Yandex was not satisfactory.
dpq··on Worst Case
> Sophie Schmieg is a high-level cryptography/security Googler, and Knows What She’s Talking About. She refers to the Carrington Event, a major solar storm (“Coronal Mass Ejection” they say) that happened in 1859, and severely disrupted the world’s telegraph system for about eight hours. This is an example of a Solar proton event. If/when one happens, it’s going to seriously suck for astronouts and for anyone who who depends on aerial radio-frequency communications.

TL;DR: the data center itself is probably quite safe from whatever the author meant here.

This is not entirely correct. The author confuses different things (and misspells the word "astronaut").

* An solar energetic particle event (SEP) is what's the most dangerous thing for astronauts, in part because there's going to be very little advance warning, but also because these high-energy particles can penetrate the inadequate shielding of a spacecraft and fry electronics (physically disrupting microchips) or damage biological tissues. But that's a non-issue for the rest of us: ground-level enhancements due to SEP events are rare.

* Carrington event's main source was a (probably double) coronal mass ejection, or a CME. This is a different phenomenon from an SEP. You can think of it this way: a CME is like a dam breaking down and you getting flooded by huge amounts of relatively slowly moving water masses, while an SEP is like getting shot at by a water cannon accelerating a relatively tiny stream to supersonic speeds. But the thing is that the particles in the CME again do not penetrate the magnetosphere and reach the atmosphere directly. Rather, the increased pressure of the solar wind causes changes in the magnetosphere's shape, which (a) "squeezes" field lines to lower latitudes, (b) causes something called "reconnection" in the magnetosphere tail, essentially slinging particles coasting along on the magnetic field lines in the tail back to the Earth (and causing auroras as they slam in the atmosphere), and (c) strengthens the ring current, which causes depression in the magnetic field, and this (changing magnetic field) in turn induces substantial currents in extended conductors such as telegraph lines or metal pipelines. But I imagine that this is going to be harmless to electronics, the main vulnerability is actually power lines feeding the data centers: volatility of magnetic field during even the biggest storms is on the order of several hundred nanoTeslas.

While the research in question is quite interesting, I recommend to skip the linked Academic Times post and head to the original paper instead:

https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/202...

The Academic Times post contains multiple inaccuracies and incorrect statements, as if the author only has a very approximate idea about what they are writing about (source: am a space scientist).

dpq··on Medical researcher discovers integration, gets 75 citations (2007)
The paper in question can be found with Sci-Hub. Amusingly enough, it contains the following:

> Three formulas have been developed by Alder (3), Vecchio et al. (4), and Wolever et al. (5) to calculate the total area under a curve

[3] Alder I: A New Look at Geometry. New York, The John Day Company, 1966.

This book is in turn available in archive.org:

https://archive.org/details/B-001-001-934/page/n269/mode/2up

So basically the author in question didn't even bother to read the relevant part of the book she referenced, and also misunderstood the explanation of the Area and Integral chapter as something that Irving Alder developed.

I didn't bother looking up the other two references to help preserve my sanity.

dpq··on Why Databricks Is Winning
We've had mixed experience with Databricks, to be honest. The quality and responsiveness of support we were getting was not worth the amount of issues we were seeing + the considerable cost, so we decided to use "exit strategy to DIY Spark" (using the original post's terms) instead and we're pretty happy so far.
dpq··on Discovering Dennis Ritchie’s Lost Dissertation
Fascinating and sad. I'd like to tell a similar story with a happier ending. I was looking for the first volume of JH Schroeter's observations of Mercury (published in 1788!) when I was writing my own PhD, and found it thanks to contacting a group of fans who were working on restoring and collecting his heritage in the Lilienthal observatory. All of my previous efforts had failed, but I learned my lesson here: if you want something hard to get, look for people who might be obsessed with the subject.
dpq··on Destruction of Nuclear Bombs Using Ultra-High Energy Neutrino Beam (2003)
This immediately reminded me a very old book by Bob Shaw: https://en.wikipedia.org/wiki/Ground_Zero_Man

The tech in the book was no less fictitious but sounded kinda cool: a neutron resonator, with a beam being targeted on the Moon and being reflected to the Earth, widening sufficiently to cover the whole planet (no idea how or why it would affect warheads on the other side).

dpq··on Ask HN: What's your quarantine side project?
The "AI" part here is a bug, not a feature. I wouldn't have to do it if I had an API for sending requests, or a condo-provided app, or at least if the concierge service used e.g. Telegram officially. Since neither of these is true, I had to resort to a workaround.
dpq··on Ask HN: What's your quarantine side project?
I live in a condo with a concierge service, and I need to order passes for delivery guys with a phone call. Naturally, this got very boring very quickly, so I made a Chrome extension which upon a click connects to a Voximplant app which calls the concierge, receives his voice input, forwards it to Dialogflow, and uses the intent recognized by DF to play back recorded audio tracks of my voice asking for a pass, answering questions or thanking the concierge.

I'm thinking about making the extension intercept the traffic to the website of my favorite delivery services and automatically place the call so the button click also won't be required.

That's incorrect; Postmates, for one, uses Phantom Auto (https://www.forbes.com/sites/alanohnsman/2019/09/23/postmate...), and they definitely operate on public roads.

dpq··on Things that I think will be important in the next decade
I think the parent is worried about the possible mandatory ubiquity of AR devices more than anything. As long as skipping a tech is socially acceptable and does not impose impractical costs (try living without interacting with a computer or a phone in a big city for a month and see how well it goes), AR vendors will have to have consumers interests in mind. As soon as AR becomes pragmatically unavoidable, vendors can and will exploit their leverage to impose additional costs on consumers to their own benefit, because opting out of AR will be even worse than swallowing it whole (welcome to game theory).
dpq··on A Week in the Life of a McDonald’s Cashier
I suspect we'll see high-paying jobs getting automated even faster, so her newly acquired skills may become obsolete before she graduates (also, she won't be able to afford the tuition fees). I don't think there's an answer to this problem: Nash equilibria cannot be easily beaten unless someone is imposing the rules and enforcing compliance... which probably won't happen.
dpq··on Why does F = ma?
It directly follows from the assumptions that space is isotropic and homogeneous. I recall that there was a short and elegant proof of this link in Landau and Lifshits vol 1; you may want to look it up.

For the better or worse, this is the standard language for modern academic writing. Do not blame the authors if this social convention is not to your liking.
dpq··on Why Richard Stallman Doesn’t Matter
The point of the author being? Since he has poor manners, or Asperger's syndrome, or he lacks vision to lead the free software movement into the future, then it's okay to plant news stories, coat them with outrageous not-technically-lies and perform character assassination on him?
dpq··on Unsteady income in young adulthood linked to thinking problems in middle age
Do you object to the notion that the USSR, like any country, was in a way an imaginary entity, or to the notion that it mainly ceased to exist because the its citizens decided to imagine something else and actually pulled it off?
dpq··on Unsteady income in young adulthood linked to thinking problems in middle age
While generally you are of course correct, this is not always the case. Some facets of reality have been willed/believed into existence. Nations and social orders are real, but only exist as long as people believe in them. For example, when in 1991 people stopped believing in the existence of the USSR, it was erased from the objective reality in a very brief span of time.

It can be similarly argued that the modern income/opportunity distribution owes its continues existence to the fact that enough people believe that it exists and is lawful.

dpq··on Identifying a person through walls from video footage, using only WiFi
> The question you should ask yourself is: in what kind of society do I want to live and do my actions contribute to it and if so at what cost? What if everybody acted like I did?

But then of course this is the wrong question to ask. This is nothing more but a complicated version of a multi-party, repeated Prisoner's Dilemma problem. Except that you don't know your negative payoff when an opponent chooses to defect, but it may well be minus infinity (you get holocausted or nuked into paleolith). And then defection by any single party gets you the negative payoff. So if you only ask the question you suggest and ignore the rest of the options, you are doomed.

I'm afraid that the world's politicians (most of them at least) are completely sane, and all this "race to the bottom" stuff going on is just the result of the game theory & life being what it is.

dpq··on In Defense of Richard Stallman
...and does a great job explaining his pov. It's not like he's saying that sexual assaults do not exist, and people should be able to rape / immodestly touch whoever they please with impunity.

> Sexual assault: The term is applied to a broad range of actions, ranging from stealing a kiss to rape, as well as other things in between. It acts as propaganda for treating them the same.

> claiming they were actually willing

Did you even bother to read the emails or at the very least the article? This misconception is exactly what's being argued there, that Stallman said something clearly different.

> Ignoring a legal age of consent

By doing what, raping someone underage? Or rather expressing his opinion that it's ridiculous that when in one state the age of consent is 16, in another one it's 18, and yet people are judged morally and criminally for failing to distinguish between these two? So basically what you're saying is that possessing a non-standard opinion and criticizing existing laws should make you a non-person. I believe you'd feel very much at home in the USSR, the communist party had the same ideas.

> How popular would gnu be if it had someone who was better at communication involved?

Also, how popular would gnu be if the US had a copyright reform, or if we lived in a fairy world with unicorns? There is no point to such questions: if there ever was a person who could be a worthy replacement of rms at the helm of FSF, they preferred to remain invisible. So the most plausible scenario is not "someone like rms but better", it's "nobody remotely as good at all".

In that case, I recommend you to read about the story of Douglas Lenat's Eurisco engine and the TCS Traveler game. It's kinda old but fascinating.
dpq··on Google’s rivals opt out of search engine auction, calling it ‘anti-competitive’
In this case, Ecosia would still rant about it. They would only change their complaint text from "what about non-profit oriented search engines like us?" to "what about search engines nobody has ever heard about like us?". Interestingly enough, they use Bing API for actually producing SERPs, so basically this is a PR stunt for not getting free access to a marketing method that is irrelevant to user experience. While their claimed goal of promoting afforestation is rational/noble, I consider their argumentation in this case to be disingenuous.
