When you're talking about controlling money, politics matter more than "technical merit".

Libra is invite only and they invited their business friends.

Libra consortium is based in Switzerland, so the businesses involved have guaranteed essentially zero government oversight.

Libra's owners have complete control over how much currency, the currency exchange rate, and even inflation rates (note that inflation is actually a tax on wealth).

I can't regulate it. I can't get my government to regulate it. I can't get a non-partisan consortium to regulate it (eg, Bitcoin). Businesses proven to put profits first have complete control. I have everything to lose and nothing to gain.

I don't care about the technical merit; everything about this stinks.

EDIT: and all that is before the privacy aspect. While accounts may be "anonymous", Facebook can use their data to identify you anyway. I don't like these big date companies tracking my friends or website visits. I certainly don't want them tracking my money too.

There's also the wrongthink aspect. Recent leaks from different companies seem to show them exerting political power and banning dissent. My political opinions may align with their now, but I'd bet anything that sooner or later, I'll disagree with them on something. I don't want my financial stability based on a platform that punishes me for thinking or believing "the wrong thing" (which could just be saying something critical about the companies in control).

Libra giving economic power to companies is straight out of fascism.
Libra feels like a great new avenue for physical, violent crime.
You can do so much better using a native app than a webapp. UDP transport is really important for real-time communication.
To my understanding, taxes and COL are much higher in the UK, so the disparity is even worse than it appears.
I don't get it. What's the need for an open source slack alternative?
You probably learned about the telomere length, not the shortening rate.
> My guess is still ... that because of the enormous capacitance of the earth, the light bulb would still light up even though no clear circuit is formed.

Your statement implies that you are viewing the earth as a huge, perfect, capacitor. And by "perfect" I mean no series resistance.

In reality, the earth is a relatively poor electrical conductor (i.e., a high resistance [1]) and so where your mental model breaks is omitting that resistance from consideration in your model.

I.e., the equivalent circuit your 'experiment' produces would be:

G-----bulb------R--C

The "R" and "C" above are the capacitance and resistance of the earth. Yes, there is an amount of C present, but there is also a quite large series "R" present as well. And it is that resistance that results in a very limited current flow from your theoretical experiment. Too low of a flow to illuminate the bulb.

"It’s easy to assume from the headlines that Libra is only associated with Facebook, but that is not the case."

With the post on.... Facebook.com
A custom URL scheme would at least provide an opportunity to confirm launching Zoom, even if Zoom itself didn’t confirm joining s particular meeting (which I agree it should).
As one who grew up reading sci-fi such as Asimov's, I would strongly hope that we go ahead and colonise the universe soon. There's a lot more space out there. And perhaps eventually we could live in a simulation a-la Greg Egan.
are you normalizing for how many fte are in the average household? i'm guessing there are a lot of 2-working-parent households now than there were in 1970. and possibly more working kids still living with their parents too.

when you consider this shift, it might allow for a reduction in wages.

just speculation. i haven't looked at the data.

> Libra consortium is based in Switzerland, so the businesses involved have guaranteed essentially zero government oversight.

Do you really think a massive US company using some Switzerland corporation is going to protect Facebook and their investors against any regulatory scrutiny?
The defininition from Herlihy and Wing (https://cs.brown.edu/~mph/HerlihyW90/p463-herlihy.pdf), page 471. More informally, aphyr's definition from https://aphyr.com/posts/313-strong-consistency-models works well:

> each operation appears to take effect atomically at some point between its invocation and completion.

Here, operations are on single values (the paper calls them objects). So they are things like "add 1 to x" and not things like "read y and add its value to x".
I'm trying to think of the real-world implications and how this would play out.

Normally this would be pretty obvious, wouldn't it? Users would see Zoom open into some weird meeting, and close it.

Presuming the exploit cannot avoid bringing the Zoom app to the foreground when it joins the meeting and activates the camera/mic. If it can do that and stay in the background, all bets are off.

In spite of its obviousness, it's still pretty darn scary --

Scenario 1: malicious website/app opens link while you're sitting there.

You're sitting in front of your computer, you see Zoom open, you're like "WTF?!", close that shit, uninstall Zoom; hopefully discover how to permanently remove it (it otherwise leaves a localhost http server running that can reinstall itself).

But crap the hijackers have, even with a few seconds of video: your face, your surroundings, the audio of your surroundings, all of which can increasingly be fingerprinted. That alone is very scary. Just to be in an unintentional meeting for a moment is very disturbing. A violation of sorts.

Scenario 2: malicious website/app delays opening the link until some threshold of mouse/KB inactivity is reached.

Activate the Zoom link and hope the person is AFK. Spy on their home/office/whatever. Also a violation.

Are there other scenarios I am missing?

Personal note 1: I'm happy I switched to a Linux laptop after finding last year's MBPs disappointing (and the TB revolting; I have a physical escape key!).

Personal note 2: I do actually like Zoom a lot, it's an awesome video conferencing app. But this should be fixed for Mac users.
Any tips on how to get your friends to actually use the social network? I've tried and failed with Slack and Mastodon.

I wouldn't blame the new people. You can't possibly keep up with a huge code base as Windows when you can't implement anything smart as it can always break something somewhere. You need huge tests just to change a small thing.

It would give them a better return to just make a new OS from scratch while keep supporting Windows for the next 10 years (maybe 20 for extended support) and let it slowly fade.

Or better yet, take the Edge route and use Linux underneath and change the appearance to MS' taste, have binary compatibility layer and call it Windows.
Ah, so a slider, posing as a knob.
Why is the web client (on Chrome, etc) so bad on Zoom ? I mean, people are building Google Earth on the browser .Its not just the bad video experience - even the product experience is seriously broken.

For example, the default audio setting when you sign in to the web video client is to connect using PHONE AUDIO. In case you figure out how to click the tab to use computer audio...it breaks down a couple of time in asking for browser permissions (camera, mic). It is unusually bad for something that is supposed to be that good.

there are all these articles about the comparisons - https://webrtchacks.com/zoom-avoids-using-webrtc/

https://bloggeek.me/webrtc-vs-zoom-video-quality/

hangouts still rules when it comes to web based video conferencing. And for countries with massive linux based usage (like India), Zoom is not a very viable option.
In theory, sure. In practice, the miner implementations are the ones controlling the chain. The only difference is, I can name the CEOs and leaders of many of the Libra companies, I don't know who the leaders of the mining pools are.
This makes the most sense for one of procedures and follow ups within weeks timeframe.

With employers providing healthcare, out of pocket price often is affordable, and nobody would bother that over a few thousands of dollars difference. However, companies end up paying the price (most often large employers self insure), and that is hidden from the employee.

It almost makes sense if companies lobbied for something like this for once....

Not sure I follow the CORS angle. The linked stackoverflow question mostly seemed to be someone who was confused about how CORS works, and the issue in the Google Chrome tracker was closed as WontFix because they couldn't reproduce it and said it should work.

I'm nearly positive that CORS from localhost works OK. I set this up all the time for local development. For example, I run a client CRA app on localhost:3000 and an API on localhost:3001. The API sets the CORS headers and the CRA app can make requests to it.

If this is correct then I believe all Zoom needed to do is have their localhost application set CORS headers for their production domain. This would have allowed AJAX communication and only allowed it for Javascript running on their domain. Instead they did this totally hacky method that lets the whole world interact with the localhost server...

Maybe I missed something but if they could have done this the right way and didn't that is much worse IMO...
Sometimes you do need someone with a vision to make the calls instead of a consensus. Especially when that consensus involves people on the receiving end of lobbying.

Which is to say, maybe we can start making lobbying less of a thing.
This is really depending on your view, but the moment you step outside of lists and use arrays, you are keeping modern CPU architecture in mind. And all of a sudden all those wonder car/cdr/cons concepts as well as things built upon it no longer holds, which, again depending on the view, actually harms the abstractions in Lisp, and we are actually back at the same page with all the other programming languages.

Also, when you are promoting something, it might not a good idea to compare against Python when it comes to speed, but when talking maintainability, only C is talking as a target here.
Ask HN: Applying Machine Learning to Earthquake Data
Hi all, I'm from Ridgecrest, the site of the recent double earthquakes in California. It's been a crazy weekend where the entire town has become obsessed with whether or not we are going to have another big one or not. I noticed that the USGS has a lot of earthquake data available via API and I was wondering if anyone was working on applying machine learning techniques to that data. I found a few news articles discussing people doing this but I was wondering if anyone was doing something more open source, perhaps.
Crypto isn't the reason why Libra is dangerous, Facebook is.

If Facebook was launching their own business-controlled currency that was backed by an SQL database, you'd see the exact same reaction. The crypto part is just an implementation detail, what people are actually upset about is corporations trying to seize control of our currency.
If you want to really break down their viewpoint on the situation, lets translate their PR statement line by line:

> Zoom believes in giving our customers the power to choose how they want to Zoom.

Zoom believes if their app isn't convenient to use, their customers have the power to leave their ass, as they are in an incredibly competitive market.

> This includes whether they want a seamless experience in joining a meeting with microphone and video automatically enabled, or if they want to manually enable these input devices after joining a meeting.

This includes making sure that they aren't asked to provide confirmation to access their camera/microphone, which impedes the convenience of the app to all participants. Less clicks equals less thinking.

> Such configuration options are available in the Zoom Meeting client audio and video settings.

Stop complaining about this as we have given ourselves a legally compelling user defined control hidden in a single tab deep within our preferences.

> However, we also recognize the desire by some customers to have a confirmation dialog before joining a meeting.

We can tell you aren't going to drop this.

> Based on your recommendations and feature requests from other customers, the Zoomteam [sic] is evaluating options for such a feature, as well as additional account level controls over user input device settings. We will be sure to keep you informed of our plans in this regard.

We don't care. We have lots of users, and lots of success having this option turned on by default. The support costs alone telling non-technical people how to turn on their cameras don't make it worth it.
Belated edit: Anything that does something that you don't want, while pretending to be something that you do want, is malware. Especially if it goes out of the way to do that, evading limits, and hides what it's doing.

Okay, sure, but: many physical attributes, social perceptions, and pervasive mental habits probably do become increasingly solidified, even if fatalism about it is counterproductive. Sure, there's plenty of late bloomers, but how many of them do you get from a broken late starting point, and how many do you get from people who worked slowly and methodically and did the right slow things earlier on, taking care of their minds, bodies, social connections, growing their resources, gaining experiences, broadening and/or fine-tuning their abilities, and so on? Do fit/rich/popular/etc. 35-year-olds regularly get there from a truly broken (including internally!) state at 31, or is it more that they actually took all the advice about regular exercise/investing/graciousness/etc. back when they were 25, kept taking it, and maybe despaired in the moment about it not seeming to work while actually stacking up tons of invisible long-term bonuses?

I'm trying to come off about a decade of poor habits myself, due to a number of factors which are undoubtedly my responsibility but which it's not clear whether I could have realistically avoided. I've had some minor successes but have never really stabilized so far, including in all the little things like the above. I don't usually see this case handled clearly in the “it's okay to be a late bloomer!” inspiration crowd. (More personally, it doesn't help that the things I most want to do in life probably require being exceptional in specific ways that I'm not sure I can predict in advance and not just “successful” in a generic sort of way, and beyond a certain limited extent, I don't consider the wanting-what-I-have approach to be a viable one (except insofar as having that attitude on the face of things may make it more likely to reach my original desires anyway).)

I'm trying to convince myself to try anyway and it's hellishly difficult.
This makes the wrong assumption that happiness comes with success. Success doesn’t bring happiness. If anything, being happy in the first place is what gives you a better chance at achieving success.

Employer health insurance rarely covers everything, and with how inflated medical costs are in the US you easily end up paying lots of money out of pocket.

The other part of it is that it doesn’t cost an arm and a leg to get a nursing license or degree in the UK, at least not as bad as the US.

Ask HN: Any startups interested in pitching on shark tank style stream?
I am looking for any startups that would be interested in appearing on a shark tank style twitch stream. The pitch would roughly consist of a 5-10 min video describing the business (founders will be asked to prepare this beforehand), then the founders will do a live Q&A session with the investors, then the investors will make the founders offers.

I have a few investors who have expressed interest in appearing on our first few episodes and I am looking for any businesses that are interested so that I can start scheduling the streams.

Please leave a comment with a link to your website or a description of your business idea as well as an email or some kind of contact info if you are interested! I would also love to hear any thoughts people have on this show as well.

I think your forgetting the effects of mining on water quality. Acid mine drainage from mines is a significant problem worldwide and water doesn't just sit around[1]. The Ok Tedi mine is an example of a mine that has far reaching environmental consequences[2].

Yeah, I totally suffer from this far too much.

Intellectually, I understand that much of the success of my peers of which I'm envious, has nothing to do with my abilities, per se, but more to do with luck and personality differences. I am who I am, and that affects the probabilities of who I meet and when, and what opportunities I'm willing to chase when they arise. I know this, and realize the, primarily, financial success of my peers does not imply that I'm a failure. But. It sure feels like I'm a failure. Mostly because of the expectation that I was supposed to succeed sooner.

But, as the article states, I do try to remember to compare my current self to my past self instead. When I do that, I can objectively see great life improvements and milestones achieved. Just not at the same times as others I know.

I have to constantly remind myself all the time of the sort of advice found in this article: to realize just how far I've come on my own journey, and that the journey is far from over.

Editor integrations that aren’t aware of build systems are a huge issue. Without awareness into the build system, its basically all just guesswork.

For languages like Go and Rust, this is partly solved by putting tooling into the language and standardizing the build system. But even for languages that have build systems, there’s reasons to use other build systems.

As far as I know, very few build systems used in the open world have readily available integration with tooling. However, I think this is temporary. As an example, Bazel and Go should play well together in the near future:

https://github.com/bazelbuild/rules_go/issues/512

Hopefully, other languages will make mechanisms for code intelligence to integrate with build systems. This is especially important if you want a good developer experience across multiple programming languages.

Perhaps the more scalable (in terms of supporting many languages x many build tools) alternative would actually be an inverse relation, a future language server architecture where the build tool orchestrates the language servers. Who knows.

BSD 2.x is tbe most insane OS ever. It is a backport from Vax Unix 4.x -- which used real virtual memory, often "lots" of it (2MB or even more!), 32-bit registers -- back to the 16-bit PDP-11, which had two (count 'em) 8Kbyte mappable pages in its 64K address range, and could swap 8 other pages into each. It came with all the same utilities as Vax Unix, except the networking bits.

We were so happy when we got a big -- 3" high, 6-platter 5.25" 20M -- Shugart disk. Didn't know we needed to recompile the kernel so it wouldn't swap in the middle of the fs (which had been at one end of the old 5M disk).
This just in: Bad behavior is still bad behavior when it's possible to mitigate it on the user side.

Consider how many people use Zoom and don't even know that Hacker News exists.
