Has there ever been a case of a medical device being hacked to do realworld physical harm? Considering the billions that will need to be spent to secure future devices, are there not perhaps other areas of healthcare where the same money could save more lives?
Buzzword bingo is more difficult to play with NNs than throwing some (misunderstood) p-values around for people that understand a bit about stats/optimization/etc. but aren't at the bleeding edge (i.e. a typical MBA with an outdated tech degree).
Wow, this is great. Thanks for sharing!
It's weird for me to think of this as a forgotten technology having gone to Penn State where all of campus was heated by a district steam system.

Between east and west campus, they have a capacity of 700,000 lbs of steam per hour.

"Would you want your car or an aircraft you're on piloted by neural net the actions of which can't be explained?"
Actually, if the net is properly trained to reduce overfitting and is shown to work on out of sample data - yes. On the flip side of this argument, a person can do something inexplicable and invent a plausible explanation after the fact that seems and feels safe and correct, but is actually wrong.

you can't experiment with new ideas if there are severe social consequences for experimentation.

because experimentation often fails. and public failures lead to getting discredited and kicked out of the discourse. people who experiment while using their real identities probably can't get back in.

It follows from the fact that sizeof (char) == 1 and CHAR_BITS >= 8 that sizeof (char) == sizeof (uint8_t), but strictly speaking I don't know that the standard guarantees that uint8_t is an alias of unsigned char and could as well be a distinct type.
I have yet to see an educational content provider that isn't primarily funded from Patreon, direct sponsorships ("This video is sponsored by..." lynda.com, Audible, Skillshare, etc etc) or produced by an entity that has relies on external streams of revenue (e.g. BBC, PBS).

Heck, even the "trash pop" part of YouTube (e.g. drama channels) don't seem to primarily rely on ad revenue anymore. And most of the gaming channels seem to actually prefer Twitch (but either want to editorialise their content rather than upload raw streams or only still use YT because they want a more diversified revenue stream).

YouTube's initial appeal was that it was a "marketplace of ideas" and everybody could upload videos of pretty much anything and build an audience and (eventually) earn a few bucks from advertising. Recently that marketplace has increasingly shifted to promote what's already popular and YouTube has actively brought in established content producers from TV while also algorithmically demonetizing "lesser" channels (note: this doesn't mean less-viewed channels or channels with fewer subscribers) with little to no means of appeal. The gold rush when it was actually financially viable to make a living off the ad revenue and fund your video production are long gone for the vast majority of creators.

Not quite. There’s no VPN tunnel - no IPSec tunnel is being set up, even on loopback.

The reason the “VPN” icon appears is because VPN profiles are how you override iOS network settings on unmanaged devices: which can include just DNS. Any time a profile is ‘active’, the icon appears.

You could generate your own unsigned profile to do the same, if you were so inclined.

I’ve always made this joke about Tobacco. It’s a parasite that modifies our brain chemistry to make us physically dependent upon it.

It feels a little more “HaHaOnlySerious” with Tobacco, because it is clearly harmful to its “host organism,” whereas cultivated livestock and Cannabis (or Coffee) are arguably good for humans.
Wow. That's just short-sighted. Left-handers comprise between 5% and 30% of the potential customer base. More if you consider that there are far fewer models of mice suitable for left-handed use available.
It is dangerous because it's reactive. And since it's reactive it will disappear in a short while.
I found that as soon as I expected people to make mistakes driving, those mistakes bothered me much less. When I held strangers to high regard; I was always disappointed.

Moving from reactionary to anticipatory made me a much calmer person (in practice, it's hard to fulfill all the time).

It's very unlikely but definitely possible. If the meteor is fast enough and targets outer earth atmosphere, it an enter outer atmosphere, slow down, light up due to friction, then escape earth atmosphere vertically. The only problem with this scenario is that meteor has to be much faster than Mach 2, unlike what pilots reported. But it's easily possible they saw a Mach 12 meteor and thought it's Mach 2.

This is the most troubling data from the study for me. It's natural that people will hold opinions for which they don't have evidence, since we can't be experts on everything (e.g. "I trust my friend, who thinks that"), but the fact that half the population hold opinions that they would not change, given any amount of evidence, is actually somewhat terrifying.
While I truly appreciate emacs and vim, I had the same problem. Ultimately I went with IntelliJ IDEA and a plug-in for Clojure called Cursive. It's served me well; getting past the environment challenges and into the language itself was a godsend.

Lessons from Content Marketing Myself (aka Blogging) for Five Years
I feel like you outlined the problem pretty well.

Amazon, because they have information and economic advantage, can effectively manipulate the price of any good they want to make it uneconomical for any other company to play.

That's a single company having outsized power to determine the state of the market.

Using your example let's say that no other company can sell diapers online. That means for consumers that either don't want to or can't buy from Amazon, they are materially hurt from the lack of competition. Not only that, if they tried to start their own, they would be crushed just like the others. So in the end it's anti competition and increases friction for new business creation. A fundamental tenet of markets is that diverse competition is the primary forcing mechanism to ensure accessibility and quality.

The only possible argument here is that it's possible to have a singular organization that provides everything better than a diverse competitive market could. Neither history nor theory supports this thesis and the secondary effect on economies and political power compounds the downsides.
PostHaven is $5/month, but it is much better than medium. They add a tiny little chip with the logo and get out of the way.
The amount of fuel that you're quoting assumes that we don't ever reprocess the spent fuel. While the US doesn't do this due to proliferation concerns, it's possible to dramatically increase the longevity of nuclear power by doing so. This is likely what Oklo is doing.

All we need are a couple of centuries to develop better technology than nuclear. We don't need it forever. It buys us time until we can develop storage and eliminate the need for fueled baseload power entirely.
In any case, it is stupid to give one platform all the power (see YouTube). Internet should be decentralized.
> How can a science-centric site get it so wrong?

Write software that A/B tests various titles. Measure the income from advertising click-throughs. Expand to A/B test various articles as well, optimizing for appeal to the kind of bored person who is susceptible to ordering miracle skin-creams at 2am.

Presto, crappy click-bait.

If it was an isolated attack, the damage is probably nil, but if combined with a rogue certificate authority you can do some pretty in-depth spying.
This is basically the all-American argument of "sure, the advertising is a complete lie but it's the consumer's fault for being gullible".

YouTube Kids presents itself as specifically for kids. You don't expect weird fetish porn on daytime kids TV and it's completely reasonable to expect a similar level of moderation for an app that positions itself as an equivalent of that.

Blaming the parents really understates how much YouTube has fucked this one up. YT relies on a wonky algorithm and crowdsourcing to moderate its content at scale but their dirty little (open) secret is that this is error prone and exploitable. In a typical Google way they thought they could eliminate paid humans from the equation and still deliver quality -- they can't, and it's entirely their fault.

If a company misrepresents a product in a way that results it to cause harm when used exactly as advertised, it's the company's fault.
Perhaps there could be, but not with the ruthless efficiency and disregard to environmental damage that farming in export-based agrarian economies tends to happen. We mop it up, because we don't care, and the damage done is far, far away.
LinkedIn embarrassed me a bit with one-click-sending a line I thought I could edit/extend before sending.
And it tastes really good, which is why it's being used. It's a saturated fat that nobody has heard of.
Its interesting that you've been down voted. I'm not suggesting that you are correct or wrong, but I'd geniunely like to hear a philosopher or somesuch clever thinker talk at length on this topic - are they the same? are they different? is the ability to get through a difficult physical experience such as pain related to being able to work at a task you show no interest in for hours? Is it a single trait that you either have or don't, or do some people have remarkable discipline when it comes to office work and others are disciplined when it comes to gardening or cooking for hours with passion all day every day? Is it something that is geniunely in a person's character, or is it to do with other things (do people with discpline just get more sleep/have a better upbringing/have interesting work to do etc?)

I don't want to pass any judgement nor assume the answers to any of these questions - I'd like to see/hear/read discussion on it.
For what it's worth I think this is a beautifully designed app. The usability and user experience is great. Yes, it does just one simple thing but it does so in a smooth and elegant way.
> To clarify you're saying that you are ok with someone selling your software?

Yes. I contribute to and create software with licences that permit it.

In a world with copyright I prefer GPL-type licenses, in a world without copyright everything would be MIT-like.

A legal requirement to attribute might be nice but I don't really care. I think that the legal system should deal with matters of importance, not social politeness.

> Or any company could make a closed source distribution of linux?

Sure. They wouldn't be able to prevent anyone from copying it.

Ultimately I can't really see a viable business model for it that doesn't already exist - e.g. Android is already essentially closed source, partly due to a bunch of binary blobs and partly due to all of the infrastructure built up around the platform.
That is true. I only 3d print trinkets for games, so PLA is great. Never have used ABS but the stories about the small has kept me away.

For the purposes of attempting to understand why people continue to believe in things when there is much scientific evidence to the contrary, I felt the list they chose was very representative of relevant topics that fit this criteria. If you were to attempt to balance what you see as bias in this study, what are some specific examples that you feel would improve it?
Not knowing anything about how the project works, they state their read latency is on the order of 5us and write latency is on the order of 15us. On this synopsis, they also mention that one mechanism they deal with is scale. So, I think your guess correct in that they likely replicate writes across multiple nodes. Then if any single node goes down, they still have a valid valid for a given key. Writes could then be persisted to disk asynchronously.

This is just another way of saying that people are uneducated fools.

I look at the loss of basic rights in the US and just shake my head. People are falling all over each other to support gun control and mass surveillance not because there is any rational basis for any of it but because they are complete idiots. We are shitting away our freedom and our democracy each day and very few people actually care. And beating up on conservatives is just another part of the plan to disenfranchise, marginalize, and otherwise ruin the lives of those of us who are not collectivists.

"For the purposes of attempting to understand why people continue to believe in things when there is much scientific evidence to the contrary,"

Let me just stop you right there. It wasn't very long ago that scientists were certain the earth was the center of the universe. Science is incredibly fungible and new discoveries make old ones obsolete all the time. Also, science has been hijacked by the collectivists to promote their collectivist, Leninist agenda and again, the gang piles right on--destroy Western Civilization and see what befalls you. See if anyone cares about science when they can't get a can of food to feed 4 people.
Again, who cares? Consumer protection isn't about letting you taste some weird cola. It is about price.

I cut out news nearly entirely. I've been happier. Especially political news.
Well for example - printed objects are generally not foodsafe. They are fine to touch and whatnot, but they have too many little niches for food that I would not 3d print myself a spoon..
a more interesting thought experiment is what would happen if you described the same phenomenon, framed in a way which superficial and reactive people would agree with rather than disagree with:

"there are more male dunces in society . . . in other words, women were less likely to be dunces."

my guess is that it wouldn't be very destructive to your career at all -- but maybe i'm wrong on that point. of course, if i'm right, this effect would be entirely a result of incomplete or incorrect interpretation of the principles by the readers.
Interesting. I think the system you are describing is a variation of a "two pipe steam" system that is not very common these days. More common systems have have an air vent, and do run on a continuous cycle.

Holohan describes the differences here: https://heatinghelp.com/systems-help-center/a-steam-heating-...

He also points out that the failure point of the system you have is that the "steam traps" tend to fail frequently and silently. The system still heats, but runs less efficiently. He says the traps typically have only a 3 year lifespan.

Joel Spolsky (if you don’t know him, he was one of the first “Celebrity Bloggers” in tech culture) gave me a piece of advice more than a decade ago: Own your own domain and publish under it, that way you always control your content and the links to your content.

If my blog was raganwald.githubpages.com, GitHub could theoretically decide that githubpages needed to be deeply integrated with Windows or some other foolishness, and I’d be screwed.

But since my blog appears to the world as raganwald.com, I can leave GitHub Pages whenever I like, and all the links will continue to work. It's about long-term control, and for that you need:

1. Control your content, ideally with a copy of the source on your own devices at all time, in an open format with an ecosystem of tooling, and;

2. Control your domain name.
I want to believe this is a good thing, but I can’t get that whole “we block Tor users” campaign out of my mind.
A cool tiny bit of trivia about RAMCloud: that's from this project that the Raft consensus algorithm emerged! (https://raft.github.io/raft.pdf)

Right now, I think that the algo is used in RAMCloud via LogCabin (https://github.com/logcabin/logcabin).

Raft is more practical (as in "well specified") than Paxos and closest to its lesser known cousin, VR (Viewstamped Replication). Beyond the academic genealogy of the project, what is interesting here is the fact that usability is a first-class concern. Clearly the fact that it was born out of a real/breathing project was a driving factor.

It wasn't just an academic being creative. To pick a notorious example, have a quick look at Leslie Lamport's paper on Paxos: you are never quite sure whether what you are reading is a distributed systems paper or a vintage edition of the Holy Bible.

So Raft had great timing too. It came after decades of clumsy (because novel!) systems research on consensus algos and from a laboratory of practitioners, hence its designers knew exactly how previous attempts were deficient with respect to their own needs. And it turns out these overlapped with a lot of people's. There is wisdom to be learnt from this.

Also, on another note I think that's funny because this narrative reads exactly like a startup-story!

I'm expecting downvotes, but self hosted wordpress could work for you.
In our little corner of northeast Ohio (east side inner ring Cleveland suburbs), the -majority- of homes use steam heating, as they were constructed in the late 19th and early 20th century. Never quite occurred to me that this is a historical/geographical oddity.

There's at least one HVAC company around here that still specializes in boilers and radiators. We had our boiler replaced last year and the system tuned up - there's hardly any water hammer or hissing now and as other commenters have mentioned, the heat feels great.
Wordpress. I prefer older technology for things that have been long solved already

Rebuilding my blog from scratch at the moment (using my own theme), it's not so bad dealing with PHP and wordpress.

I really dislike not fully owning my content, especially with medium or middle-ware like disqus which is pretty much required with jekyll. Medium has really poor syntax color formatting as well.

Security is not really a big issue for me, especially if you pick a good hosting provider, and follow basic 101 practices.

I'll still use medium to link back to my blog though (not really doing it at the moment though).
Ask HN: How to return into programming after 10 years of management?
I programmed for like 7 years and then gradually went to CEO position and did not program for almost 10 years. I never was great as a programmer, but I was fast and good prototyper.

Now I want to get back to programming and do it RIGHT. Any advices how to start? Did someone went similar path before?
I really like this interpretation, but to take it at face value would be to assume that other approaches do not offer actionable steps? or at the very least do not suggest that their steps actually work?
Naturally it's correct that no matter what you do you don't always suceed, but does the fact that people eat this up suggest that for most people there are no actions they can take to be successful?
immutability and snapshotting - like git
That's the very point — while US were to be wasting megatons on Soviet cities without a plan B, Soviet paratroopers would be already landing on their lawn, and their main force moving down whatever left of enemy land force with a rain of short range tactical nukes.
Nice, everyone is posting their favourite CMS, again.

I use https://getgrav.org because I like flat-file CMS.

Maybe there are some photographers here: http://koken.me (CMS for photographers).

Another idea: Use a static page generator and Amazon's S3 with this neat blackhat trick - https://www.blackhatworld.com/seo/how-one-website-exploited-... (mildly joking).

OT: I pay 0.19$/month for my blog hosting including domain with around 500 views/month (just a personal blog). Many services cost 5$/month, I don't think that's cheap.

edit: Medium is for visibility. I know many SEO experts who use it extensively to increase their rankings. Its UX might be annoying for some, but its true value lies in its popularity and outreach.
Launch ICO. Security vs. Utility Tokens
Of course they are. They are competing for eyeballs, user actions and for ads.
Its far from the first time, the issue is that when things go wrong those in power can't be replaced.
My guess is that yes, absolutely, but very few people know about it / a Doctor or nurse was blamed.

Medical system security does not seem very good. When I was operating in the area a while back, one comment I kept seeing was similar to yours. "Yes, the security is bad, but the good these devices do outweighs the bad."

I agree with that, but my follow-up has always been, why can't these devices continue to help patients, but in a secure way? The manufacturers really don't want to spend the money to try and have some form of a security posture?

Rhetorical question. At the end of the day, my pessimistic view is that nothing will happen until some firm finally proves that there has been a high profile attack, there is an ensuing media firestorm, and the regulation process starts happening.
