People fall into some interesting traps when it comes to technology.

A huge one is around FTL travel and communication. Any weird idea for this gets attention basically because people want it to be true. You'll often find defenses like "well, people once said it was impossible to [get to space,fly,go to the Moon]", which is a specious argument and (deliberately) ignores all the very real problems.

Another is putting a lot of weight in fiction. This applies to the FTL issue too (eg Star Trek, Star Wars) but goes well beyond it. There are a whole bunch of literary devices that make for an interesting read eg teleportation, telepathy, telekinesis, levitation, (unaided) flying, any form of magic and space flight working like flight in an atmosphere.

VAR has a big latency problem to contend with. Even AR does but in this case it's just rendering latency. But that's still significant.
Sometimes it seems so predictable that someone will say it that I think they are being deliberately ignorant and trolling.
Websites selling abortion pills are sharing sensitive data with Google
If you've got 1M files, your alternatives include:

a) 1M files in a single directory

b) 1k directories with 1k files in each

c) 1k aggregate files with 1k files in each

d) 1 aggregate file with 1M files in it

I think there's some filesystems that will work with option a, but any filesystem should work ok with the other options. Options c and d will make rsync much faster as you eliminate millions of syscalls.
oil usually has mixtures of hydrocarbons like this. Refineries use processes like fractional distillation to separate the components so that they can be used separately, or processes like cracking are used which convert longer chain hydrocarbons into simpler hydrocarbons.
Side-comment: is there a type of shadowban with HN where my posts do not make it into the frontpage, even 2 or 3 or more pages deep?

I've seen this with a few of my posts recently where they appear in the 'new' and 'show' or 'ask' tabs, but not the frontpage.. even 300 posts deep while similarly aged and upvoted posts are on second page.

edit: now it's on the frontpage! Guess it just had to hit a vote threshold.

> there is always the risk of total nonsense hidden somewhere in the middle

This is true of human-generated code as well. Trust me: Reviewing other people's code is my day job.

It's exceptionally rare that a malicious actor is trying to sneak something into the code. The common scenario is the developer who's new to the project not fully understanding how everything works so they copy & paste something they think is necessary but ultimately isn't and could in fact be very wrong. Just like how ChatGPT works.
A friend and I did a (literal) blind taste test with impossible/USDA organic beef/beyond. I was excited to do this as we don't get Impossible in Europe. We baked our own buns etc, cooked to temp with a probe, got some nice cheese on top good stuff. We also did a blind tests of the proteins on their own, and in a plain burger. Neither of us had any trouble picking out which product was which, but it was really interesting.

Beyond was the most divisive. It has a very distinct flavour which isn't anything like beef, and not everyone likes. I think it's fine, but it's more of a tasty protein than a beef replacement.

Impossible is a really interesting product. It tastes good, texture is good, and I would happily eat a burger made from it. I can definitely tell the difference side-by-side, but I think if it's cooked well-done in a ragu or meatballs, it would be more difficult to tell.

The main complaint I have is that it both can be quite hard to form and have a tendency to turn into sludge. So you have to handle them very cold before the fat melts.

In Switzerland meat is expensive. Organic ground/minced beef from Farmy is something like $15-20/lb. Organic chicken breast is $50/lb (around $15/breast). Beyond is about $10/lb so there is certainly a cost saving to be had. All the supermarkets have extensive plant based options and vegetarianism/veganism is pretty common here. I think it'll be interesting to see how this pans out globally with improved animal welfare. My next experiment is eggs (which are almost 1 CHF/per!). Unfortunately the egg substitutes are almost the same price per weight from what I can see.
I actually feel like this is a good argument for normalizing the fact that probably everyone has thoughts about suicide (as OP said, thinking about the implications versus considering).

I remember a period of my life where I was struggling a bit more than normal with anxiety, and my creative / intrusive brain was like "how about you think on the concept of suicide?" to which my brain responded "wow now you're thinking about suicide, you should really seek help".

In reality, it was just an intrusive thought. But the fact that my brain jumped on that thought, and ruminated on it as "if the thought popped into my head, maybe I'm not OK", that was the thing that caused problems.
"recent open messaging alternatives seem to decide to develop new protocols rather than build on top of XMPP"

XMPP is reasonably specifically a protocol for Instant Messaging. You can theoretically do whatever you want with it, and you can theoretically turn it into a mechanism for delivering social-networking style asynchronous messaging, but it doesn't necessarily bring a lot of value, and it makes a certain amount of fundamental architecture decisions that aren't necessarily the best for a social network.

I am interpreting your "recent open messaging alternatives" in the social network framework because my perception is the major ones you might be thinking about are those things, like Mastodon and such. I'm not aware of hot new open IM protocols that are just "old school" IM.

Sure, but hydro is a rather limited resource. This could allegedly scale way further.
sorry, maybe the "simply" was misplaced. The issue is that pretty much every "real" word (as in, not made up) is taken by now. Even for other names that I didn't like as much, the situation was quite similar (most domains taken or expensive).
The question is therefore about common alternatives used by startups to have a "close enough" domain compared to their name.

My one experience with Prosody was writing a plugin to extend Jitsi Meet to show a list of the available conferences and their participants before you join (never got around to developing it beyond the prototype stage, but at least a deliverable that came out of it is a
thorough explanation of how to use lib-jitsi-meet that I felt was missing: https://github.com/solarkraft/lib-jitsi-meet-demo - I still believe the feature to be important for allowing spontaneous meetups -don't you want to steal my idea?).

What the hell, I hated it. The parts I needed were super under-documented and Lua/their implementation of it lacks so many features normal languages have - I had to copy a lot of things together from the web to answer basic questions like "what properties does this object have".

To their credit the people in the chat room were very responsive and helpful; I probably should've asked there earlier instead of making sure I don't ask a redundant question.

How do you develop your Prosody plugins? Did I miss some obvious way to set things up so that it's actually convenient? I used the Docker Jitsi Meet setup.

And, while you're here, maybe you could explain the reasoning behind break-out rooms not just being their own conferences (or so it seems to me).
Beautiful and interesting stuff! I have never heard of copepods before, but have now and will have to do some more reading.

Not to pick on them, but I found this illuminating on how religions present such a myopic view of life and what it means to be alive on Earth. Religions seems incapable of fitting their model over the apparent continuum of life. It was also somewhat humorous to read this.

OP's wife praised them for taking care of the issue with a level head. That's very different from being chill. Not anti-chill, but a different dimension. In fact, it's probably a better trait!
That's demonstrably untrue.
I think most of what you're referring to was Control Panel.

Control Panel was unique in settings applying immediately. Pretty much every app's preferences (or other settings) were a modal dialog with OK/Cancel, however.

So it was a step forwards when iOS's Settings app changed from checkboxes to toggles, because this reflected the immediate change. And now with Ventura, macOS has finally caught up as well.
That's fair. They have to be a willing participant. It is just so infinitely hard to tell someone, especially someone you love and support, and who's support you so greatly want (and need), "you lack empathy", especially after telling them already several times you don't feel cared for. Maybe phrasing is part of the issue, and starting with "you lack empathy" isn't quite the right way to attack this issue and is an unnecessary attack on my partner. But, where to begin with them then?

I'll admit I wrote that comment frustrated and after not sleeping great after reading this thread.
Other than really obscure options, OTP is pretty much available anywhere/everywhere in terms of device support.

Now account for the energy, land, labor, materials, and environmental externalities required to bring a cow from birth to the table at industrial scale (all the way from birth, through the animal's ~1.5 years of life (?), through slaughter, butchering, packing, distribution to the consumer, etc.), and compare that to a proportionate amount of beans and rice.
Odd. Personally there is something exceedingly off-putting in the aftertaste of Impossible and I occasionally get rancid smelling burps afterwards. Beyond is fine, but still not in my top 5 veggie burgers.
Death of the Author
Adjectives do matter. The author seemed to clearly express the opinion that our systems are not expressing intelligence artificial or otherwise. The author also expressed some attributes of what they regard as intelligence but that our systems are not exhibiting.

Personally, I am a fan of "efficient cross domain maximization" as a definition but I feel it only implies the self establishment of value systems over the relative values of domains. The reality is that we don't have a perfect definition of intelligence or the spectrum but we roughly hold up ourselves as the example. This is a deep topic I'm not going to burn further time on for HN.

I'd suggest that intelligence is an emergent property of the interaction of dumb systems. The lack of a clear line is a symptom of our lack of clear definition. More impactfuly, or lack of understanding of how brains produce/host it.

I think a real objection is that the user of the term of AI is associated with the disappointment and drying up of funding in academic research that had been correlated to irresponsible use of the language. The apologists came up with AGI but this is humans. Some people think their marketing benefits by saying "AI" and most of the world has neither the expertise or product knowledge to call them on it. So too do we have a word "literally" with a definition of "figuratively".
I can't pretend to know what the original test writers had in mind. However, I actually think this question serves a different purpose than to determine if you had actually considered stealing from an employer. These types of questions are better suited to determine if someone can walk the corporate walk and talk the corporate talk. They don't want a low level employee to go off on a customer, or make rude remarks, or otherwise say "between you and me, fuck this company lmaoooo", because that opens them up to litigation. On that front, I would say they achieved their goal.

The _obvious_ answer to this question, if you want a job, is "no". Anyone that answers "yes" is a liability, regardless of their actual intention to steal.

Some people just don't care about the same things. And some people also don't have the creativity, joy or whatever to cook a vegetarian meal. People are just different and for some, biting into a burger or eating a piece of chicken gives them some kind of joy. Maybe they even associate some kind of lifestyle, identity with that.
I think there is no point arguing these principles over and over. People are different.
> The title of the submission is also "Nationwide FAA weather reporting outage"

Yeah, but the title is made up. There is noting in the official report about this being "nationwide".

The report only states that there is a metar outage consisting of 167 stations.

It doesn't provide any context on which stations are missing or how they are distributed.

Adding "nationwide" to the title is pure FUD IMO.
Below the "spec table" they have an example run with household plastic waste.

- 3.5 hours @ 1 kW (may be an overestimate of power since it says as a guide)

- Converts 400g of plastic to 286g of oil, so with a "dirtier" source of plastic its a ~70% return.

Also more data here [0] with ratios in the 60-90% range.

Edit: On that page it also says "As you look into the data you can understand our machine can produce high grade oil mixture of gasoline, kerosene, diesel oil and little heavy oil. The oil can be used as recycled fuel for electric power generator without refining." The second sentence seems like a bit of a reach, that there would not be some intermediary step.
The cops gave you a problem. They gave you something that was not theirs to give.

If it had been me then I would have said "great, now I have to go and get legal advice". I would have refused them.

But at the same time what am I supposed to do? Unload them in the impound lot and drive away? That'd piss off the cops, who could possibly fine me for flytipping.

It's a shitty position for the cops to put you in.

By "sludge content" are you referring to mis/disinformation, or empty content?

IMO, TikTok is fast approaching FB content curation/data quality issues (which proved quite costly for FB).

Oftentimes, effective "sludge" reduction requires sufficient user feedback (thumbs down/report/comments) and algorithmic learning. Contested concepts and "pleasure posts" can make threshold tuning a bit tricky (e.g., how empty is too empty; how misinformed is too misinformed), as imperfection encourages discourse/engagement.

Valid question! Honest answer: the folk involved (including me) have more experience with Prosody these days.

Jabber.org previously ran ejabberd for years, in fact that's what it was running when I joined the admin team (I was also running ejabberd on my personal server at the time). We had quite a few problems with it back then, and for various reasons decided to switch to something else to help bring some stability to the service. This is all in the distant past (literally 10+ years ago), and I know for sure that the several problems we kept encountering on jabber.org have been fixed long ago. Many other large XMPP services run ejabberd successfully, including conversations.im.

But now that Prosody is more mature, the team has more experience with it, and it has a few more features than ejabberd that we'd like to support, it's what makes the most sense for us right now.

If you're trying to decide between ejabberd and Prosody, they average out to being equivalent in terms of protocol support. ejabberd has clustering, and a commercial option for people who want that. Prosody has a strong focus on extensibility, and has hundreds of community modules at https://modules.prosody.im which provide various kinds of extra functionality.

I don't think either project is overall "better" than the other, but each has strengths and weaknesses for specific use cases.
I'm a prolific user of all things Retool. We are automating away our more mundane tasks with Workflows, but with Mobile we're redefining how our business is running. We have more visibility over our field sales, more control in our warehouses and ambitions to do more.
To elaborate this point a bit: the "lottery" concept requires you to believe there's like a queue of souls and they each get allocated to different bodies, and you're lucky you got a fancy one instead of a microscopic shrimp. A different -- and to me, more plausible -- way to look at it is that "you" are an emergent property of a specific complex organism. How you actually emerge is a fascinating and difficult discussion, but putting aside the mechanics, the implication of this framing is that "you could have been a microscopic shrimp" is meaningless, like asking "what if that cloud were instead a bowl of soup?"

You may want to read the actual arguments that are being made [1]. Keep in mind that the US Congress passed a law in the 1990s (including section 230) that says you can't sue someone for x, y, and z. But then they passed another law in the 2000s that says you can sue somebody for a, b, and c. Resolving this apparent contradiction is exactly the point of the Supreme Court taking up this case.

> If your unit tests are not testing discrete units, instead testing the combined behaviour of many units

This is a very naive idea of unit tests. In the real world applications have a dependency hierarchy with more than two levels. If you want to test anything other than the leaves in that hierarchy you are by definition testing the behaviour of many units.

Sounds like what you're saying is that unit tests are only applicable to leaves in the dependency hierarchy. I could agree with that, but that's not what the world describes as unit tests. That would also make unit tests quite useless.
