It is the same process we see everywhere that massive cost overruns and unlimited delays manifest. Modern management methods can control cost and schedule where that is an actual goal. Where they don't demonstrates the actual goal. Every penny of cost overrun goes into some pocket. Smart management ensures many, many pocketholders are allied to keep the gravy train running.
Even with modern medical care the worst version of influenza had approximately 60% fatality rate (H5N1). https://en.wikipedia.org/wiki/Influenza_A_virus_subtype_H5N1

COVID is already significantly more dangerous than normal Influenza so making that kind of jump is far from impossible

The alternatives where Whitney Duan is not in China seem implausible to me.

What's the plausible alternative? That Duan is not in China, and has simply been in hiding for years for unexplained reasons?

Or maybe, she's actually been dead for years and her ex-husband made up the phone calls to get publicity for his book?

The CCP has a long track record of disappearing people without trial. Jack Ma is the most famous/recent example. It's completely plausible that they've done the same to Duan, much more plausible than those alternatives.

But sure, let's forget about morals for a second (lives lost and all that) and be very cold and cynical about the pricing.

Perhaps the stupidest, most vacuous comment I've read this week.
Do you actually want to ditch screen time outside work or do you just think it’s a good idea for some reason?

If you really don’t want to do it, you won’t do it. If you really do want to do it, you will — you won’t need some secret trick or activity.

Personally, I don’t think there’s anything wrong with screen time outside of work. Sure I go outside and run/bike a lot. But I like screens and I like looking at them. I’m not going to fight that.
You’re thinking of Wall Street while I’m talking about Main Street.
Time has its own cost, especially multi-stage construction projects.

Being delayed imposes costs on downstream work, which must now be ready but in some kind of holding pattern, which imposes costs on work downstream of that work.

So a large part of throwing "Manhattan project" / excess funding (and the potential savings by just funding it that way from the start) is avoiding these delays, to the extent possible.

It costs +$200,000 to tackle some challenge in a critical piece? Sometimes it's cheaper just to pay.
QUIC was brought to the ietf for standardization and they decided to separate the transport protocol from the application protocol and potentially support other application protocols over quic in the future, resulting in http3 becoming a separate spec.

What about social media? The division, damage to politics and mental health, those are also forms of harm even though they are legal. What about fossil fuels?
> What are the best practices...

It largely depends on why you are spending more time than you want on screens. If you have an addiction to the screens, I would suggest counseling/therapy. Meditation will help slow you down so you can listen to your thoughts and emotions, which can help you figure out why you're addicted.

Or maybe you aren't addicted but it's a compulsive thing. In that case, keep the phone and computer (and any device you don't want to look at) far from you, and inconvenient to get to. Maybe even lock them away in your safe for a time. But still find out why you're experiencing this compulsion, either with self reflection or counseling.

If you look at screens more than you'd like because you're bored, find a list of hobbies online (about a year ago I found 2 or 3 lists that had a lot of options, and altogether had over 200 unique hobby suggestions). Go through the list(s) and make a shorter list of the ones that were most interesting to you. Start pursuing those.

If you just want some ideas though, here are some that come to mind that are probably the most beneficial, in no particular order:

- Mindfulness practice

- Workout and/or martial arts

- Practice cooking

- Gardening (it's amazing to cook food that came from your own garden)

- Long walks in nature

- Anything artistic: play an instrument, paint, draw, etc

- Woodworking

- Archery

Rkt took deliberate aim at the problem of reliably running docker containers as systemd services, and as one of the early rkt developers I can honestly say I did so grudgingly after various meetings convincing me we had no choice.

If the Docker folks hadn't deliberately obstructed our ability to reliably run Docker containers as systemd services, none of this would have been necessary. We certainly had better things to spend our time on.
At the end of the day, most large banks, most large insurance firms, most credit processors, most large government agencies use z/OS and z/15 class machines. I work on mainframes and they are the source of data for just about all lower level platforms and companies.
In theory there is no difference between theory and practice.

It would be great if you people tried reading a history book for once. In particular, stories of people who believed these ideas were great and (despite a bunch of red flags) tried to act on that belief by immigrating to the Soviet Union in 1920s and 1930s, to help build the promised utopia. Spoiler alert: it doesn't end well for most of them.

First the Plug in Prius was using Lithium ion back in 2010 page 1: https://techinfo.toyota.com/techInfoPortal/staticcontent/en/... Non plug in hybrids want different battery chemistry as the charge / discharge cycles are much more frequent.

Second that timeline from 2016 to 2018 was Panasonic cells.

To be clear Tesla does employ battery experts directly and invests serious money into R&D, however that’s really just a pile of money for the time period I was talking about without Panasonic. Anyone can try and kick things off from scratch, without the IP and technical expertise from Panasonic Tesla wouldn’t have had those kinds of turnaround times.

As to everyone kicking things off yea, but Toyota is already spending ~10 billion on battery manufacturing over the next 8 years. It’s very different to ramp that up than simply starting from scratch.
That would make sense if he's comparing only against fossil fuels. But what was written was:

> I like to think of solar, batteries, fission, and wind as compelling ways to go mostly carbon free and lower energy costs about 2x over the next 20 years or so.

> Fusion is what reduces energy cost potentially another 10x, which really changes the game for lots of things. Exciting stuff. Kudos to this team.

If the 10x is from avoiding fossil fuels, why does fusion get that credit, but the other non-fossil sources don't?
isnt that what you would expect. just wait till they have the whole place a company town.
That seems a bit unfair since it literally comes from the direct translation of 'idiot proof'.

It's true that you can benefit from idiot-proof design without being an idiot, but I would argue that you could market a microwave that doesn't turn off when you open the door, plastered with warnings and maybe a mandatory course on how to operate it. An idiot-proof version would have safeguards that everyone could benefit from, but then saying that it's a fundamentally different concept just seems needlessly combative.
Please make sure you include private repositories in the design from the start.
Such a great series. Word is he's working on book 4, but motivation is low. Can't say I blame him, he has a large body of work...which is also part of the problem; too many projects.
Kiting/Powerkiting is pretty cool because you form a hobby around the movement of the air, which often times many of us ignore. Once you start kiting you notice an entire dimension of nature and its quirks.

Rock climbing or some other fear inducing hobby will cause you to forget about screens completely for the duration of the activity. Feeling your life and safety are at risk has a way of focusing the mind.
> So it's distributed blue checkmark verification by the people for the people.

You could look at it that way.

> The way you say social forwards might work suggest your system would make it so what happened to Trump can't happen to anyone else, that he would "own" his followership, take it with him, so it can't be taken away.

Basically, yes.

> That's a nice idea but that would require the social network to allow (or not disallow) this open distributed checkmark system in some form, wouldn't it?

The idea is that this is a useful system for other distributed/decentralized systems, not so much for Twitter/FB. Sure, centralized systems could use it if it got critical mass, but yes in general it requires integration.

The goal is really to build a system that abstracts away the need to build an identity system in other systems.

So this was built with things like Mastodon in mind: right now, if I move servers, I leave my network behind. There's no real mechanism for moving my network with me, and many other distributed/decentralized networks suffer from the same issue.

> If allowed, this would only encourage the exiled party to create a new account 1:1 on their system, effectively hindering their own moderation efforts.

More like, they can spin up a new account on another instance that will have them.

But also, if I am sick of seeing messages from Trump, I can simply block Trump's Stamp identity and then I wouldn't see his messages no matter where he is. I tend to favor more p2p approaches where possible, meaning the idea of banning someone is not really a thing, and rather individuals are free to (dis)associate with each other as they see fit.

> Then imagine how hard it is to appeal a distributed blacklist.

It's as easy as appealing to one participant in the network given that they would all have to agree on the blacklist. This is in contrast to centralized systems where once you're banned, you're gone forever.

> Unless I am misunderstanding, using stamp means I would lose power across the board on pseudo-anonymous social network providers by revealing who I am even once.

On centralized systems, yes. But they likely wouldn't care about Stamp anyway. On decentralized systems, you lose nothing while gaining the ability to have your network follow you.

Imagine how much Bitcoin we could mine with that kind of energy source...
The energy of a diamagnetic material is lower in a lower magnetic field, so there's a force pushing it away from higher fields. This force is proportional to the gradient of the field. In a constant magnetic field, there will be no change in energy and so no force on the diamagnetic material.
As someone only casually knowledgable in this area (e.g. I use docker for some of my home automation thingies, I still haven't wrapped my head fully around what Kubernetes is beyond something like a way to manage a bunch of similar containers? VMs? eg)..

Docker, the kabillion dollar company, never had a chance. We all recognize the potential and actual problems when some very crucial piece of infrastructure is only free/open source and not maintained -- but this is what happens when it is "overmaintained" I.e. it makes sense to invest big in something that is good and could be crucial; but only if you can both keep up quality AND stave off competitors -- and in this case, competitors aren't just other companies, but free software in general. It's kind of funny, in a way, Docker made itself a target for "good competition" by being so visible, in a way that e.g. "curl" didn't.

Either way, I always knew "Docker the kabillion dollar company" was a stupid stupid bet. Small company, great bet. But this? Destined to fail.
How about making a tool that lets insiders leak documents about illegal actions that corporations and governments are suppressing the release of?

I mean, there's statistically very few real secrets, but there's many, many coverups, unethical or illegal decisions, and scads of corruption. Seems like the need is to help leakers rather than help those who would keep blunders, coverups and illegal actions secret.

> To the extent that they made downgrading a paid option, not upgrading.

Except that they didn't. With even a little bit of research you can easily find out that they made skipping updates a paid feature, and then even removed that after negative feedback!

People were even talking about downgrading below the version that introduced the 'paid update skipping', so any way you look at it, your comment doesn't make any sense.

Those are fair points, but I’m not convinced that fur doesn’t have an impact.

Anecdotally, I have a mild cat allergy and own a cat. Vacuuming our sofa regularly makes a huge difference, as it gets rid of the fur stuck to it. It goes from feeling scratchy to totally fine.

Maybe clumps of fur are common with super fluffy pets? Ours is a shorthair and shedding leaves single hairs lying around.

Matter is conserved, sure, but fur with dander stuck to it from saliva versus skin with saliva on it, surely makes a difference?

Show HN: Arbington.com – 1,200 online courses from todays top instructors
Hi everybody! Today I launched arbington.com, a new learning website that's affordable and treats the content creators better than other leading platforms (as in we share much more profit than our competitors and communicate with them regularly).

I've taught somewhere around a half million people how to code over the last 10 years on various platforms, and I think it's time to support our content creators better!

I personally coded about 98% of this website using Django, Postgres and Tailwind CSS and we spent the last 4-5 months talking with over 200 instructors to get this off the ground, and ended up launching today with just over 1,200 available courses.

Now the hard part: I'm looking for feedback, namely UX feedback (I know the design is still a bit rough around the edges, it's a never ending work in progress). Is there anything feels "off" or flows in an awkward direction? Any free tips or tricks from the community that could help us grow in the right direction would be absolutely amazing!

We did a little bit of user testing already and have some good feedback coming in, but I thought: hey the best place to ask for feedback is probably from people in a similar field - Hacker News!

Or if people have questions about the tech stack, how it works, etc. I'm always happy to talk tech with people!

Oh I would agree; if being conservative always worked - but my point is I've frequently been berated for taking a tablet out as well as for keeping it on at the same airport.

I kind of understand overall - At a busy airport, being overly conservative (taking out tablets, shoes, belts, coins etc when not needed) can be seen as "wasting people's time". It's the inconsistency of rules and their application that sometimes bugs me - There's no 100% winning strategy.

I wouldn’t say I’m all in, but this is what I use at work, and I think it’s better than the existing alternatives I could be using instead.
Journalists quote promoters. When something has no reasonable prospect of ever producing, promoters resort to lying. Journalists are not responsible for it, although experience should make them less credulous. But pie in the sky sells better than skepticism.
Once we've shown this can work successfully, I think people will get excited and investment money will rush in. Ideally, we'll perfect the technology and make it cheaper and more efficient, just like any other technology. If an MIT-borne fusion startup IPOs and they have a working demonstration reactor, I would probably invest.

I think the hope is that with economies of scale, we could build really huge fusion plants one day, and drive down the cost of energy to less than a cent per KWh, and of course completely eliminate our dependency on fossil fuels. If energy becomes that cheap, we could use electricity to produce hydrocarbons from CO2 and water to power airplanes and such. Currently, we can imagine short-distance flights being electrically powered, but transatlantic flights are going to be difficult to achieve with batteries.
It's a common error to think that fission power plants aren't being built because of "stigma". The actual problem is failed economics. Fusion promises to be even more expensive, for the reasons I explained.

It's not clear why one should expect fusion to have good experience effects. Fission didn't, and the non-nuclear parts of fusion power plants will be mature technologies.
I suspect that there is a tendency to pick more powerful and complex tools and infrastructure than needed. For us as engineers it's easy to foresee some of the scaling-related, technical problems of the far future. It's so tempting to prepare for those, especially if you need to learn a new technology anyways and it looks great on your resume. In addition everyone knows intellectually that their own startup is unlikely to reach Google scale, but we do badly want to believed it will. So maybe the right bet is to always put your money on the more powerful and complex technology as long as the complexity is inherent and not incidental. Of course this is also limited to infrastructure. Consumer products and other markets would be totally different
