It seems surprising to me that there is not more information on the website regarding what gas this gas-filled lenticular-shaped aerostat thing is floating with. I understand they are aerostatic and the gas needs to be lighter than air, but that doesn't leave many options that are not helium I guess. And then in order to drop whatever they haul down, they'll need to either let it escape or contain it somewhere else, or spend energy at keeping it down somehow.
There is drama everywhere: on the Linux kernel, on Github, Python, Systemd,... People are getting annoyed all the time
This is one of github usernames I could infer without even looking at the link, so many workflows it broke with no one being able to fix it. I know that the state of modules in node is on an off side, but at this point, just fuck ESM. And fuck these bold moves that break things without waiting for big players (e.g. webpack, typescript, which are real software trying to fix the web and cannot change overnight) to catch up. This is delusional. I’m cleaning my repos from these toyish deps weekly.
Two words: Japanese Denim
I was wondering about the same thing. It doesn't seem to be explained on the company site.

The only thing I could come up with is to have neutral buoyancy air blatters that can expand/contract. These would be inside the volume of buoyant gas but connected to the outside air. Then pump the buoyant gas into a pressure tank to reduce buoyancy, or release it from the tank to increase buoyancy.
Or, until we have enough excess electricity, we could replace methane steam reformation with pyrolysis.

I know, right. I called that shit out to HR and management. I sell my time for money, and I'm working more hours than ever, and those hours are more stressful than they used to be.
>> that is 100mx100mx25m

That’s huge!

I wondered how big was the hindenberg, wiki claims 245m long and 41m wide, and 41m tall (excl. cabin). Only 200k litres of gas capacity. 232k tonnes lift.
My official Raspberry Pi 4 USB-C power supply would like to have a word with you. It just sends out power.
If it was a little earlier than 1980 it might be more realistic - inflation didn’t go below 6% between 1975 and 1983 and was often into double digits at that time

Identity isn’t in opposition to password IMO. (Username might be closer to opposing password.)

The major point of a password is authentication (that the user logging in as username Foo is actually the user they claim to be). If there’s something that you can’t change or revoke, but no one else can imitate it, I agree it’s identity, but seemingly in the good sense of that phrase (as in my family can identify me in both the naming sense, “I am @sokoloff”, and verify the authenticity of my claim “Yup, I confirm that is @sokoloff”).
So many people are weirded out in this thread, but unless you use placement-new there’s no need to know about this at all… This is just an escape hatch to solve a weird interaction between const members and placement-new.

Yeah. I just moved my family domain to O365 and I’m planning to migrate the business domains I manage over as well. It’s a much better product for the price and business users will be happy. It’s just been so low priority for me to figure out migrations and with this kick in the pants for the family domain, I have a good story for migrations now.

Honestly I think this will end up proving to be a misstep akin to reader.
That's not true. For connections initiated from the v4 network, you can deploy v6 on the network, use a proxy, or use 6to4, 6rd or Teredo. For connections initiated from v6, you can use NAT64. There are also various approaches to deploy one protocol over the other, like 6over4, DS-lite, 464xlat, MAP-T/E, 4rd or LW4over6.

Pretty much every interoperability method that can work with v4 is supported by v6. How is that an interoperability failure?

> Pretty shit transition plan if we've only managed to get 35% of devices on v6 in 25 years.

The plan is "start using v6, then stop using v4". What better plan do you suggest?

I'd call it more like 35% in 9 years, since Google's stats say that deployment was <1% in 2013. (The time before that was spent on updating protocols, implementing the updated protocols in software and hardware, and deploying the updates, all of which are necessary prerequisites before users can show up in those stats.)

That seems like pretty decent going, given the sheer scale of what needs to be done.
Those two qualities aren't mutually exclusive.
"Still, the tremendous energy of this latest explosion, which NASA estimated to be equivalent to five to six million tons of TNT, is unlike any seen in recent decades."
Automating it away (Ansible and Docker) is a good way to reduce overhead. I barley invest any time in maintaining my infrastructure.
What's linux? What's python? What's a script?

What's a kernal? What's a symlink? What's hex? What's a hex-editor?

i_end = strnchr(bprm->buf, sizeof(bprm->buf), '\n');

What's `->buf`, `strnchr(bprm`, `sizeof(brmp`, ? Why does `\n';` have a `;` ?

FYI: I know the answers to all these questions but the idea that this article isnt for a "restricted few who have the right prior knowledge" is bizarre. It reads almost like a satire... this would be a classic case of an article where a vast amount of prior knowledge is presumed.

Who knows what a kernal is that doesnt know how to debug `/usr/local/bin/python^M` ? Some, but a vanishingly small highly priorly knowledable group.
Because there are two sides that think they know what’s best and they both use the pretense that ‘science’ has the one true answer. That causes a problem when some research shows their one true answer is wrong.

Real science doesn’t have to censor other opinions.
Very cool and thanks for sharing.

> while being defensive for WebGPU on native deployments

Because I still haven't heard a single argument against it from you that isn't extremely vague and handwavey.

For example, you skipping over my questions regarding more details on what you think makes WebGPU bad/castrated, or what is making Qt the better choice over WevGPU? (ignoring the fact that Qt doesn't seem to have a common shader language)

I'm open to hear the reasons, but it seems like your goal is to be contrarian.
> Presumably the load and the craft arrives on a truck

Nah they're absolutely gigantic and usually semi-rigid (especially if you have solar panels on top).

SkyLifter seems very cagey about the purported crane's dimensions (couldn't find anything on the subject), but the Airlander 10 (which I understand only lifts 14t) is 90 x 43 x 26... meters.

IIRC the rule of thumb is that you need 1m3 of helium to lift 1kg, to lift just a 250t payload you thus need 250000m3 of helium.

According to skylifter's "design" page the lenticular envelope has a height of 1/4th the diameter (3 units wide, 0.75 units deep). For a cylinder that's 108m wide and 27m high, so taking in account the lenticular shape we might be closer to 120m/30m (400ft wide by 100ft high). That's the size of a baseball field, and 14 stories high.

And that's only taking the payload in account, not the solar panels, not the cabin, not the engines, ...
I believe I read something about the spike protein causing inflammation
I don't see why. Currently you would subsidise a nuclear power station because it provides reliable capacity that you may not need. The customer is created artificially by the market. But if you can link nuclear with hydrogen production the customer is not artificial anymore. You could provide guarantees about future hydrogen prices instead and still get the capacity. You then get a product that helps to decarbonise other parts of the economy.
The only ever double blind RCT of the Pfizer vaccine (that done by Pfizer themselves) found 24% increase in all cause mortality (21 in vaccine arm vs 17 in placebo arm, each group 22,000 of reasonably health mostly 20-50 year olds)
I think this is a fair take, and I actually live off grid, on a boat.

But I will say one thing. I may be completely reliant on sealed batteries manufactured in a Korean factory and bought off the internet whose inner workings I only understand in very generic terms. But I spend a lot more time thinking about where my power comes from and how much of it I have left than the average person living in the average house.
(I also use a lot less, although the climate impact of that is probably offset by inefficient generation and dirty heating in the winter)
Beside all the sibling comments, avoid WinUI, regardless of 2.x or 3.x variants.

They deprecated .NET Native and C++/CX and are yet to provide any tooling that compares to them.

.NET Native is stuck in C# 7, while C++/CX got replaced by C++/WinRT with the argument that it is ISO C++ friendly, when in reality it offers the same tooling as using Visual C++ 6.0 with ATL back in the days before .NET came to be, but their developers are so stuck in COM pre-historic tooling that they don't acknowledge that.

Apparently WinUI 3.0 would be the future, with the merge WinRT and Win32, however issues pile up exponentially and even Windows 11 is making use of the deprecated UWP, as the team cannot keep up.

Since MAUI depends on WinUI 3.0, it is yet another reason why it keeps being postponed.

Windows on 2022 with Microsoft stacks MFC (yes really, much better than C++/WinRT), WinForms or WPF (eventually with C++ if required).

Otherwise Qt, Delphi or C++ Builder if enough budget, or PWAs if possible to do so.
The same applies to learning new technologies. If you're feeling stupid or unconfident it's probably a good sign that you're learning something useful.
As the wiki page itself notes though:

> On calculators, it is printed as "log", but mathematicians usually mean natural logarithm (logarithm with base e ≈ 2.71828) rather than common logarithm when they write "log".
I'm calling bullshit on this. Slick marketing driven website, low resolution photos of actual prototypes, hand-wavy FAQ and no other technical details. They claim speeds of 40 knots but does that mean that can stay stationary in 40 knot winds (the same as traveling at 40 knots) or that it can hitch a ride on high winds? The wind forces on the balloon look they would be far too high for those tiny fans to counteract even with its flying saucer shape. And solar panels to power them? Come on!

250 tonnes is A LOT to lift. Look how big a hot air balloon needs to be to lift a few passengers in a basket. Sure helium has more lifting power but it doesn't create miracles. That means the balloon would have to be absolutely massive. Far bigger than the CGI renders they show on their site. Helium is very expensive and a lot of it will leak out of a balloon like that even if you can reclaim the bulk of it back at the storage site.

I'd like to be proven wrong because the idea seems wonderful but the only thing they may be successful at doing is lifting some money from the hands of some gullible investors.
I find its healthier to assume you're dumb if you don't understand what is going on in the textbook. Its incentive to get better.

Everyone is an idiot at something.
My private Wireguard network is IPv6 only. SSH on all my remote servers listens on a random statically configured IPv6 address dedicated only for ssh. Since every server has an entire /64 prefix, a random internet scanner is never going to find it (Of course I still secure ssh properly since a man in the middle still sees what IPs I'm connecting to). Some cloud server providers started offering IPv6 only servers at a cheaper price to save money on unnecessary IPv4 addresses, so there's also a financial incentive to move non-public things to IPv6 only.
I’ve used a similar approach when visualising telemetry reliability for a whole bunch of real world assets as well as in performance/stress tests.

It’s so nice to be able to use this sort of thing in tests when the outcomes don’t represent as text naturally. Makes it super easy to eyeball a failing test and intuitively understand what the problem is.
"Hi! We built a balloon!"
"Okay."
I have read a good theory for this elsewhere: the company has a spreadsheet of "partners" somewhere that legal and accounting demands gets updated. It starts as companies which you pay but then someone insists developers add all the open source copyright owners.

Now someone took this spreadsheet with zero understanding of what curl/"Haxx Team" is and just emailed them a template.

Not giving excuses, clearly they are incompetent. But it is not some demand of service from freeloaders.
> I’d very much be in favor of mandatory pre-nups when getting married.

Everyone already gets a mandatory pre-nup when they get married. It's <whatever the default divorce law of the land in your jurisdiction> is.

IANAL, but as I understand it, having a pre-nup, in most jurisdiction is not a great shield against vindictive litigation.

There are other good reasons to get one, though.
The real problem is "living behind your means" at a generational level by putting debt in future generations. This is a problem with democracy, which incentivises short term gains over longer term. The solution is democracies that aren't allowed to accumulate long term debt over agreed upon levels.

You'll definitely be renting the crew. The skylifter website specifically mentions the one crew. And per my calculations the thing is the size of a cricket or baseball field, there is no way it'll be flying itself.
Yea I think I missed the whole web-complexity bus and am probably out of touch, but I still don’t get the use case for docker and containers and kubernets and and orchestration and all that stuff, just for a simple home setup. I serve a tiny web site, email, backups, a NAS and a few other internet services for my family, and my “stack” is vanilla Debian Stable.

Maybe I don’t know what I don’t know, but my setup works for me and I don’t really have any problems maintaining it so I figure why add all the complexity?

It always feels weird to see threads and threads of people talking about dozens of software programs I’ve never even heard of, let alone used. Maybe I’m living in the past but to me a “stack” is: OS, server, database, application. Like LAMP. Wonder when this changed!

It makes me curious about what kinds of stuff people do in their home networks that I never even considered doing.

Not by enough to stop pretty much the entire population being infected, which makes it a very questionable benefit. Mostly they just spread out the period over which everyon gets infected and that has some obvious downsides itself - the effectiveness of the vaccines against both infection and death declines rather too quickly, meaning that delaying infections can in theory lead to more deaths. As I understand it slower spread should make it easier for more infectious and vaccine-evading variants to evolve too since each intermediate step in their evolution has more of a chance to get established and outcompete the existing variant, but vaccination is still sold as a solution to the problem of new variants as well.
But this is the 21st century, everyone is perfect the way they are, no need to improve.
Alternatively, a good technical book should challenge you and it’s totally fine to only take away some percentage of it. If the whole book feels like “happily breeze through the first few chapters, and I would get that nice rush you get when you learn new stuff”, you’re most likely just wasting your time learning hardly anything substantial, since substantial learning usually isn’t a breeze.
Or "Type A" or "Type B". Sometimes I think a large part of HN readers think everything about human nature and personality can be classified, as if ready to be replaced with software in the future. Our understanding of the human mind is nowhere near that place now, and may never be.
I fixed my one case of budding RSI with Two Weird Tricks.

The important one was to make my home row on laptop and other 'standard' keyboard layouts into (approximately) QSDV-POKJ. That is to say, my palms are angled relative to the keyboard angle. Without this, the wrists are squished the whole time one is typing: that's bad and no layout can fix it, it's pure posture.

The other one was to move backspace to the cap's lock position. Turns out I delete a lot and i was doing it with a rather extreme wrist rotation and my pinky finger.

I use an ErgoDox when I can these days, but can easily spend an hour or two typing on a laptop keyboard, my spine needs a break well before my wrists would.
A lawyer friend who has colleagues working in Family Law says they (the family lawyers) describe their practice as "Feelings Court". The law itself is a guideline, adherence to the rules for e.g. contents of filings is on a meh-effort basis (beyond things that are completely objective such as tax returns).

DoomedNerd a website to save your links
First of all, thank you for the comments.

That said, I'm not claiming that you don't need any pre-requisites. Obviously this article is aimed at people who use bash or else they wouldn't be having an issue with the shebang!

There is a huge audience who knows what a kernel is (in theory) and writes shell scripts, but doesn't know how shebangs work and has never actually looked at kernel code.

My point isn't that you don't need prerequisites, rather that I think there is room for writing at a certain level while also giving people hooks to learn more.

Anyway, I do appreciate the feedback. Thank you.
A fun website i cooked up quickly, to save all my favorite website links, and yes adult stuff is also on there

> 250 tonnes is A LOT to lift. Look how big a hot air balloon needs to be to lift a few passengers in a basket. Sure helium has more lifting power but it doesn't create miracles. That means the balloon would have to be absolutely massive.

Agreed, per my calculations it'll need to be around 120m wide, and 30 deep (lifeisstillgood comes up with slightly smaller numbers of 100 x 25, possibly because they used 1.1kg / m3 where I used 1 for the lifting power of helium). That's more or less a baseball field.

And it's just for the naked payload, you still need to account for the envelope itself, the solar panels, the cabin, the engines, the batteries, and the fuel (as, per site, it has a biofuel backup). That probably adds a dozen tonnes at least (the solar panels alone would be 5-10 depending how much of the top's surface is covered). By the end you're probably looking at a men's cricket field, one on the large size.
SpaceX has to survive on its own, he can just do any project he wants. Sure, he could sell lots of Tesla stock and develop some scientific instruments but even for a rich person just dropping many billions on something experimental instrument is a bit rich.

So you want to run a space shot (2021)
I don't get why none of these companies try to get ultrarich people to finance their development by selling "air yachts". Basically strap a luxury RV with big windows to the bottom of one of these airships.

Imagine the splash you could make at your friends yacht meeting when you float in from above. Watch emperor penguins migrate or elephants in the Okavango delta from the comfort of a couch.

It's amazing the amount of engineering zoom is willing to do to work around os security.

Just because they don't want to ask user permission to do screen sharing they do this while screen shot thing.

My own experiments with this point to similar conclusions. QWERTY is not laid out that badly, really, and for me (with no RSI problems, yet) the benefits of using the default, especially being able to type on other people's computers, far outweighed any benefit from the alternate layout (Workman). However, the excursion was completely worth it for me - I switched in the first place because I never learned to touch type properly, and figured it would be easier and more fun to learn from scratch on a new layout. That was true, and soon I found I'd entirely forgotten QWERTY, so I re-learned that from scratch, touch-typing, and am about as fast and accurate as I was on the alternate layout.

IMO, external libraries are for domain-specific tasks. If something is needed in pretty much every program, it should be a part of the language or the standard library.

Also, it's much easier to use external libraries in other languages. npm install, cargo install, nimble install, cabal install, gem install, …
There is a reason why many of such frameworks have been moving into a managed layer, including Qt.
Sometimes. I read as a student a highly recommended physics book. It looked all like gibberish. I reread it after mastering the material (from other sources), and it just was gibberish.

So sometimes it is the book. (this happened because it went through like 23 editions and edition 20 was a 'modern rewrite' which killed it. The reputation and praise was gained from the older editions).
I came to admit I can't imagine how the small solar power "field" shown on top of the balloon could possible push that shape through the air - either at a reasonable speed for transport or to counteract wind. If lift isn't a problem as you pointed out above, what might work is a tethered version that basically replaced the need for a tower crane. You could develop a tethered, active mooring that was much like the four-point active anchor system the navy uses to accurately maintain position during submarine rescue.
Everywhere? The point of an explicit pre-nuptial is to opt out of what would happen by default. It's opt-out, not opt-in. If you don't have a pre-nup, then you get the standard pre-nup terms which have usually been established over a long period of time, with detailed rules about homes, children, property etc.
