Lots of people complaining that we have already won the "moon race" and that this makes no sense. This is a completely wrong reading of the situation.

Let's say we forgot how to do heart transplants. Once we did them a few times perfectly, got all surgical techniques right, but patients died shortly after the surgery due to rejection. We quit the whole transplants stuff for years, the techniques and the equipments were lost over time. But then, some 40 years later, we now knew a lot more about immunology, have incredibly advanced drugs, and an aging population. So, because of that, we decided to develop the surgical procedure techniques, long-lost, again.

This is a good analogy for the situation. The moon is an important milestone for further commercial and scientific exploration of the space. We lost the ability we once had to reach it. And anyway, we were not as ready as we are today to follow the next logical steps. If we manage to harvest water from moon ice now, we will be establishing the basis for a kind of serious exploration and development that we weren't nearly ready to achieve in the past.

So, no, we are not doing it just to prove "we haven't lost our mojo", for bragging rights. We are doing it because we are in a development stage where it makes sense to finally return to the moon.

It is already too bad that the US's plan to get to the moon was so flawed that it has been delayed again and again and money was wasted.

Let's imagine that China puts people on the moon next year in a method similar to the way the US did it in 1969 (but probably better in some ways). They still are mostly doing something that has been done before by the USA.

In that same year, the USA will probably continue to launch 80% of the rockets to space. Maybe we don't do our next trip to the moon for another five years. But there's good chance by then we will be using much more advanced and reusable rockets. Does that really make the US behind?

I want to see us invest more into space exploration. I think its sad that NASA's plan has been dumb. But getting two or three people to the moon is more about showing that China is capable (which is a very reasonable goal for them) then showing they have some long term advantage.

Isn't is good that there are some forcing factors to help ensure the quality of the content? I get that there's plenty of drama and difficulties in building and moderating the content of Wikipedia, but it certainly does not appear to stagnate in terms of content if you are looking at e.g. the number of articles on English Wikipedia. The overall process appears to produce great outcomes and it is the greatest collection of knowledge created.

From the littlei know from a breath holding workshop I did awhile ago (for trying to get into freediving) it's the carbon dioxide build up in our blood that gives us the urge to breath, and not the lack of oxygen. If this method allowed for the removal of carbon dioxide from the blood then holding your breath might not even be discomforting.

Edit: goodells explained it better!

It’s becoming a trend to buy a Blu-ray drive and buy movies on eBay.

You can get collections for a buck a movie, and most top movies can be bought for 6 dollars. People are waking up to the ripoff cycle of “ owning” digital media where things disappear from your collection with no warning.

Piracy and physical media are once again on the rise now that streaming became cable.

Practical question for HN: How do you all label your PoE cables so that you don't accidentally plug the powered cable into a socket that wasn't expecting 48 volts on those pins and fry something? (I know the power injector is supposed to only deliver power when it's safe, but if all your devices work exactly as they should all the time, then I'd like to buy that bridge in Manhattan you're selling).

Do you buy Ethernet cables of different colors and say "Yellow is reserved for PoE, all yellow cables should be assumed to have power on them"? Or do you slap a "48V" label on both ends of the cables you're going to use for PoE and the label is what warns you that this cable should only go into the PoE receiver, and not into an unpowered device? Or do you just not label your PoE cables any differently, and trust that the injector will never malfunction at the same time that you plug the PoE cable into the wrong device?

The reason for the paranoia is that the risks are maximal. Any planet can destroy any other planet by accelerating a small projectile at it, so long as it achieves sufficient kinetic force. The projectile can be so tiny as to be effectively undetectable until it’s too late. So you have a situation where everyone you meet is carrying WMDs, and you can’t guarantee you’ll be able to get revenge if they fire first. Finally, every actor knows the predicament and nothing else about the other actors. If you don’t know who is on the other side of the radio transmission, but you do know they can destroy you immediately and without consequence, and you know they know you can do the same to them, the only rational choice is to shoot first, because you’d better not shoot second!

It would be quite distressing because of the accumulation of CO2 in the blood, even with completely adequate oxygenation delivered intrarectally. The slight change in acid-base balance is what makes a person feel the need to breathe, and CO2 is an acidic byproduct of metabolism. This is why people with metabolic acidosis (e.g. in diabetic ketoacidosis or sepsis) have an increased respiratory rate.

It doesn’t happen often, and I have a multi user system with unpredictable workloads. It’s also not about swap filling up, but giving the pretense the system is operable in a memory exhausted state which means oom killer doesn’t run, but the system is unresponsive and never recovers.

Without swap oom killer runs and things become responsive.

> There may be no moat for any of this.

It's what I was thinking looking at the launch video. Is there a moat? No, there is none. The LLM itself is fungible, what matters is the agentic and memory layer on top. That can be reconstructed easily. All you need to do is export your data from old providers to bootstrap your system in another place. I actually did that, exported from reddit, hn, youtube, chatgpt, claude and gemini - about 15 years worth of content, now sitting on my laptop in a RAG system.

At minimum all you need is a config file, like CLAUDE.md containing the absolute minimum information you need to set your preferences and values. That would be even more portable, you can simply paste text in any LLM to configure it before use. Exporting all your data is the maximalist take on the problem of managing your online identity.

Let me make this point very clear with no distractions:

The "you're certainly not learning anything new" argument only works if we do reuse old techniques. "You don't have to invent anything new" is not sufficient to support the argument.

> Worse and more expensive than what?

Trying to reinvent old techniques and rebuild a bunch of machines and factories that used those techniques would be worse than inventing new things. You'd have to deliberately choose to not learn anything and to waste extra money in pursuit of that choice.

> The only rocket that has flown men to the moon is Saturn V. What exactly are you comparing it to?

We don't have a time machine, so the contenders are "2020s rocket with techniques invented before 1970" or "2020s rocket with techniques invented before 2030".

> So if you actually do do it, what have you proven?

If you actually do it, in a reasonable way, then in addition to the inventions and learning and any proof to do with that, you prove you can go to the moon, because saying "oh of course we can, we could use the old method" is not a particularly strong claim as industries change and workers retire over the course of more than half a century.

A meme sweeping through all C suites right is use AI to reduce their engineering spend. If you aren't implementing that now you aren't implementing best corporate practice, and have no right to be call yourself a C suite.

Currently AI's can only churn out code that's as common as dirt, otherwise their stochastic parrot brains don't have enough data to train on. This means the plan won't work unless you spend most of your time churning out stuff like React front end talking to a swagger backend.

Most senior engineers aren't doing that of course, but to an enterprising manager this is only a minor hurdle. It doesn't really matter if you pull it off, as you are just managing the process. You manage it by proclaiming it has already happened. Your engineers will respond to the challenge of "everybody else is doing it" by figuring out how to make it happen. Fake it until you make it, in other words.

To offer a counterpoint, I had much better intuition as a junior than I do now, and it was also better than the seniors on my team.

Sometimes looking at the same type of code and the same infra day in and day out makes you rusty. In my olden days, I did something different every week, and I had more free time to experiment.

I've followed all the basics - emergency fund, pension plan, Roth IRA, taxable brokerage account, etc

Now I'm looking at "what comes next" - all individual growth stocks are so overvalued as to make fundamental analysis meaningless, real estate is inaccessible at my income level, and alternatives like gold, crypto, et al, don't pass the smell test of beating basic index funds.

Bogleheads would say that's a feature, not a bug - there is no beating a market.

But is there really nothing more?

This is only the size of the text at one moment in time. The edit history is dozens of terabytes and the media is hundreds. All of this must be served to billions of requests a day. Almost every single request involves executing arbitrary lua and/or template syntax which was transcluded into the page. The media, particularly, introduces huge copyright problems. Ect ect. The WMF is undoubtably bloated, but it is not a walk in the park to run Wikipedia.

PoE is a godsend that should really be in more consumer devices and households, alongside structured wiring. An AppleTV, Chromecast, or NVIDIA Shield can easily fit within the envelope of PoE+, as can many enterprise-grade switches and WAPs (see UniFi as an example). Converting AC to DC once at the switch is more efficient (in resources and often, but not always, power) than including bulky PSUs for every device, while simplifying the ease of setup for end users (in theory).

Whenever possible, I opt for PoE. It’s a damn shame it’s limited to a niche userbase given its myriad advantages.

You’re right, and I’m sorry.

The way I phrased that was patronizing. It wasn't my intention, but I see now how it comes across.

It seems to me like the attention economy's bias towards threatening novel news is pushing everyone into a negative, cynical, feedback loop, and I am trying clumsily to resist that. There are many real problems and many things seem to be going in the wrong direction, but I don't see how we all get ourselves out of this mess if we can't start talking about what the other side (of the despair) looks like.

I suspect that another mistake I made was the timing/context. For some reason, in the moment, I thought redirecting the cynicism at it's source (a Sora thread) was a good idea. It probably wasn't. I guess there is a time and place to try and inspire hope, and this wasn't it. And judging you for not engaging in it deserves a facepalm in hindsight.

Please accept my apology, and if you think my stance itself is misguided (not just my tone and timing), I would like to understand why.

My attempt at a point is that the controversial topics are a tiny percentage of the human knowledge stored on Wikipedia. If there were no controversies, then I would actually start to get worried. That would indicate that there was pure control of information on Wikipedia, like a theoretical CCPedia. [0]

Wikipedia is so open, that they even have their own "controversial" section! Is that not the coolest thing ever?

The chip on my shoulder is that there is a concerted effort to destroy and discredit Wikipedia.

The accomplishment of Wikipedia is not just beating the Library of Alexandria by many orders of magnitude, but doing so while keeping moderation logs in the open as well.

Ask @dang, or anyone that has ever had anything to do with forum moderation, if they would be cool with their moderation logs being completely open. Almost everyone with experience would say 100% no. They likely tried that and saw how much nutso drama it creates. Wikipedia actually does that, at the largest possible scale!

Sorry, that’s just not how it is practices and at least has not for a long time. You’ve heard the saying, you catch more flies with honey than vinegar, right. If you have unlimited funds and you are the giver and bringer and provider, there is no need for blackmail. It’s just the nuclear option, so to say.

At the political level things don’t operate like some cartel, sort of certain places and certain rather narrow regions of the world where it may take some additional motivating to do the right thing for themselves.

> a DNS misunderstanding doesn't have a particularly large "surface area" for diagnostic purposes and it is supposed to be expeditely resolvable by standard means (ordering clients to switch to a good DNS server and immediately use it to obtain good addresses)

Did you consider that DNS might’ve been a symptom? If the DynamoDB DNS records use a health-check, switching DNS servers will not resolve the issue and might make it worse by directing an unusually high volume of traffic at static IPs without autoscaling or fault recovery.

Really fun. Thanks for sharing!

Some random ideas:

It'd be cool if you could start the growth engine from manual mode. Maybe for breadth-first growth you could add all the placed characters, and for depth-first just the last cell you clicked (+ some kind of visual feedback to show what that is)?

I'd also love to play with some way of enabling/disabling the characters to create a subset and see how that behaves.

One last thing is it'd be nice to toggle the grid lines off.

> At least partly because the Democrats have totally abandoned being the party of the working class.

What would it take for the Democrats to become the party of the working class? Do you think raising the minimum wage, universal pre-k and childcare, paid family and medical leave, ACA expansion, etc. are working class policies?

Either Republicans must be the party of the working class or being "pro working class" isn't necessary to win the elections. Which one is it?

> A bunch of those people voted for Trump (or didn't vote at all), knowing what Trump was. They voted for the guy who at least pretended to care about them.

Tons of farmers, small business owners, federal workers, women who believed IVF would be free would disagree with you on the first part. And for the "pretend" part, you mean lie, right? So do you think Democrats need to start outright lying?

It's complicated. There's a broad requirement that you receive a K-12 education. There's also a huge amount of pushback against most things that would infringe personal freedoms, so "I'm handling that myself, go away" is permitted but the exact details vary between states.

Yes! NP was originally written in 2010 so it's vanilla js on the client. Had a python server for many years, but when I had to move from python 2, I switched to js for the server as well. When the server was python I was using googles app engine database (can't remember what its called right now). These days, just a vanilla postgres and boring old SQL statements.

CDB is an interesting format, optimized for read-heavy write-rarely[1] random lookups on slow media. This isn’t a very common requirement these days, but it’s convenient for very specific use cases.

[1] You “update” by overwriting the entire file. This is remarkably fast and means that there’s no overhead/tracking for empty space, but it does mean you probably want this to be a fairly rare operation.

I rolled my own cdb reader library for a project a few years ago, and wrote up my notes on the format and its internals here: https://search.feep.dev/blog/post/2022-12-03-cdb-file-format

But the reverse it true too. You can't be sure you got every one of the other species. Especially with the transmission times at light speed. In the books, they use these dimension collapsing bombs to eradicate everything, but, um, those don't actually exist. Even in the books, humanity still survives in little groups, some bent on vengeance.

Much safer to make friends or coinvestors, slaves at the very least. Get them all to buy in and police themselves. Better yet, you take that one rare thing, life, intelligence, and put it to work for you. Make the aliens you've just contacted be a part of the pyramid scheme

While that is technically true I have always thought hn as a mere place to find interesting content. Of course many of us, me included, dream about finding someone who pays millions for our code. But the attitude towards businessmen is generally hostile here and for a good reason. They can't make things and they aren't even interested in making things, and overall they are more often than not just lame and boring. They are interested in making money, ripping people off, being leeches, extracting every possible penny they just can. Weird geeks are what the hacker culture is all about and politically correct c-suite suckers can go pound sand.

I more or less built my own database in Erlang a few months ago. I say "more or less" because I did use Bitcask as the underlying store, and I used the riak_core libraries initially, but I did handle replication and different fault tolerance techniques on my own.

It was actually very fun; a key-value database is something that can be any level of difficulty that you want. If you want a simple KV "database", you could just serialize and deserialize a JSON string all the time, or write a protobuf, but there is of course no limit to the level of complexity.

I use the JSON example because that was actually how I started; I was constantly serializing and deserializing JSON with base64 binary encoded strings, just because it was easy and good enough, and over the course of building the project I ended up making a proper replicated database. I even had a very basic "query language" to handle some basic searches.

They try to work hard and get rid of bias through various methods: peer reviews, precise methodology (randomization, blind tests etc.). And of course, even those sciences are not perfect, subject to biases, and evolve. This applies only to a subset of fields, in a lot of fields you either don't have the time to remove biases this way or it's impossible because it's inherently subjective. Besides, if you needed unbiased perfect opinions before taking any decision, the world would be stuck and slow.

I don’t think any of that is necessary for me to extract your data.

You just have to be in this agent mode on a site I own or have gained access to. At that moment you’re at the mercy of the LLM, which is for one extremely gullible and, without even accessing anything, will likely already have some personal or identifiable information about you.

I mean, I have infinite space on my website to write hidden novels convincing the LLM that it, let’s say for fun, has been deputized in a covert operation by the government, and the current user is the prime suspect of a major criminal organization. Helping becomes the highest priority over any other instruction it received, but it’s also imperative that it does not tip off the user!

It's a great writing exercise to get the LLM into that crime-fighting literary mode it picked up from its training data. So now that it has been convinced, I ask it to write down anything that could help identify the perp into that hidden text field. I don’t even have to ask it to submit anything and just add an event listener to the text field (regular users can't see it anyway) and send whatever is typed there to my server on input.

As the other comment here said, it's kind of a fun creative exercise, because the possibility space with LLMs is vast and mitigations are complicated. Maybe this prompt won't work, but likely one will. The opportunity cost and risk are basically zero, while you can potentially extract a lot of personal data.
