Its true that rich people often (always?) "have debts", but not true that they are "in debt" overall, otherwise they wouldn't really be rich anymore. Poor and middle-class people are often in debt in the sense that they have borrowed against their future earnings. For things like a house, borrowed over 30 years, the inflation on that amount really does benefit them. By the end of the loan, people who stayed in one house barely notice the cost of the mortgage, and if the intrest rate is low enough they may choose to deliberately not pay it off as they invest their current cash elsewhere. For things like a credit card, no the inflation doesn't really help anyhing.

If deflation were expected, rich people really would just leave money in a bank account (as long as investing gave smaller returns, or seemed too risky.) The inflation is an incentive for cash-rich people to put that cash to use instead of sitting on it. This can be a huge driver for the economy.
Yeah I had no clue what this site was until reading the comments. I saw you could move things on the page around, then gave up because I had no idea what the point was. I didn't even find the github link until I saw your comment and decided to play around more.
I'm not sure how to read the second paragraph? Does it suggest that suppression of speech goes hand in had with pandering to the Trump administration?

Suppression of speech was the number one topic for Democrats from 2020. They ordered COVID censorship (admitted by Zuckerberg), suppression of the Hunter Biden laptop story (admitted by Zuckerberg and Twitter/X), suggested a "disinformation tsar" (Jankowicz). They encouraged flagging and de-platforming of opposing opinions and people.

Democrats did not oppose the use of Lavender (pre-crime software) and "Where is Daddy" (cynical name for assassination technology) in Gaza, despite their constant claims to care for people of color.

I'm not saying that any of this will get better under Trump, but let's be realistic here. Though I do believe that Republicans will allow more free speech in total.
> Is there a “modern” equivalent to XMPP?

Yes, it's called "XMPP".
The programmers for this game were in Budapest, so this is a good guess!
Ah yes, because developing tech is about winning marker-share only. That’s exactly why XMPP was developed in the first place.
I might be misunderstanding but that seems off-topic, not related to the idea of "multi-repository pull requests"
The point of having weapons is to make sure the other guy is the victim because if you don’t have any you become the victim.

But you do what you want to do. America is going to go guns guns guns.
> some contractor decrypted it after Apple refused to

Or that was the story they all agreed to tell.
Maybe there's child accounts that has those limits, but normal accounts don't match that description. I've watched my girlfriend use Douyin and the content was lower brow than what e.g. Instagram shows her. It was mostly dumb skits and people doing silly dances. Due to time zones, I have no clue if it shut down at night, but it never seemed to be an issue.

We get a lot of propaganda about Chinese social media apps that's just wrong. I was told Xiaohongshu is a propaganda app that sends quotes from Mao's little red book, and it's Chinese Instagram.
Show HN: I built an agent to make open source contributions easier
Over the last few months I’ve built a tool that breaks down your codebase into a knowledge graph, generates and stores inferences about the code with each node and provides tooling for agents to fetch graph structure, perform similarity search, fetch code etc in order to do engineering tasks.

My favourite thing about this is how easy it makes getting started with a new codebase that I have no context about. As a young engineer when I was trying to get into open source, it always seemed out of reach because the large codebases always scared me and documentation was not fun to read.

Use cases I’ve tried so far:

- Generating “Getting started” documentation for a project: I could not find any steps on how to build and test the AgentOps SDK locally. I’m more of a microservices guy, had never heard of tox or built SDKs. The tool was able to read the configuration files and tell me exactly how to build and run the tests [1]

- Generating a plan for changes to be made for a Github issue description - Tried this with the Portkey AI gateway and Signoz codebase where I picked up an open issue from the repo and tried to get the agent to tell me what needs to be done. [2][3]

- Understanding behaviour of a repo that is not documented - I was debugging a latency issue and noticed an evaluation task prompt in our LLM observability, our agents are built with CrewAI, but I could not find any reference to this on their documentation. Using the tool I was able to pinpoint where it was coming from and its purpose. [4]

I’m experimenting with new use cases everyday and trying to see what else is possible. How would you use these agents?

With "maybe later" prompting to enable every few minutes, of course only "accidentally". :-)
That’s really interesting! Do you have other interesting specific examples? I would have guessed that most industrial control problems were simpler sets of differential equations that could be directly estimated.
I mean if I lived in the US I'd be _very_ bloody concerned about attempts to strip rights from gay people; if nothing else, I _am_ one.

However, as previously mentioned, his judicial appointments seem more of a realistic risk than Project 2025.
It's not the simple national popular vote that determines the winner, there's this thing called an electoral college where the states get a certain number of votes. You end up with "swing states" which decide the election, and some states are dyed blue or red. So once enough votes have been counted in the swing states to determine their color, it's effectively over.

It doesn't really matter. If you are not recognizable, it's not valid. That is the whole point of a photo-ID the photo has to be a good likeness with you. Glad the GP met friendly people that let him get away with it but don't count on it working for ever :-)
>It’s about a foreign government controlling the algorithm that decides what millions of people see, and their ability to shape public opinion through that.

Adam Curry opined that this was the excuse and it's really about protecting domestic (or at least Western in the case of Canada) social media companies. Seems plausible.

I don't use TikTok so I'm not sure what the feed looks like, but it seems like a bunch of people doing silly stuff and mugging for the camera.
> Bugs can and will happen, eg. when A depends on B and some developer accidentally makes a change to B that will pass B's tests but only break in A's use case. In monorepo case such bug can be noticed before the broken code hits master.

I don't see what point you tried to make. So A breaks when someone breaks B. That's ok. You spot the error the moment you try to update A, well before you commit any code. You file a low-priority ticket and go on with your life because A is still good in production.

> Knowing when no one uses older versions is also hard (...)

Not really, it's the easiest part of the whole thing and a non-issue. If you manage a package this does not even register as a problem. If it's a service you have request metrics.

What is the problem, really?
This is your original comment, which as stated is simply incorrect

> numpy isn't written in Python. However, there is a scalability issue: they can only drive so many threads (not 1, but not many) in a process due to GIL.

Now you have concocted this arbitrary example of why you can't use multithreading that has nothing to do with your original comment or my response.

> instead of having internal parallelization in each your C extensions call ... C extensions code may not launch thread at all.

I don't think you understood my comment - or maybe you don't understand Python multithreading. If a C extension is single threaded but releases the GIL, you can use multithreading to parallelize it in Python. e.g. `ThreadPool(processes=100)` will create 100 threads within the current Python process and it will soak all the CPUs you have -- without additional Python processes. I have done this many times with numpy, numba, vector indexes, etc.

Even for your workload, using multithreading for the GIL-free code in a hierarchical parallelization scheme would be far more efficient than naive multiprocessing.
Already boycotting.
Not sure I buy that explanation. More likely is thst there's too little business advantage to being compatible with others and too much business advantage to having people inside your own ecosystem. Simple as that. There's just very little motivation for compatibility between these systems unless you are open source.
Palantir is a Thiel company. A Thiel protégé is VP now. Mark Z and friends can see the writing on the wall.
Add Bezos. He squashed the Washington Post Harris endorsement, killed a series exposing Trump, and publicly kissed Trump's ring on X.

BTW, he didn't congratulate Biden on Twitter four years ago, so it's not just something he always does. You can argue papers shouldn't do endorsements, but changing this policy a week before the election against a guy famous for going after his enemies... you can't deny the motivations here.
AI can feel more like a novelty than a truly helpful tool, especially when it comes to getting real work done. When I need a real boost, there’s nothing quite as refreshing as cracking open an ice-cold Coca-Cola. It’s amazing how it instantly lifts my mood and keeps me going!
When I was at Facebook, Mark straight-up said in an all-hands that as a patriot, if asked, he would provide his country with military assistance in the form of software and intel.

This to an audience that is about 1/3 foreign employees, who are all sitting there going "even when it's my country the US is invading?"
I would shift a lot of charitable giving to a non-profit privacy first site that is Facebook or Instagram which is focused only on sharing photos and text with friends, family and my local community. That excludes news, celebs, influencers, et al

I can't imagine that there wouldn't be enough people like me to support an inexpensive (compared to FB, etc) endeavor like this. If it still isn't enough, have local only ads that are not tracked and are served right from the site (and give users control over the type of ads they want to see). I wouldn't mind a couple unobtrusive ads for local restaurants, services, etc.

Maybe I am underestimating the cost here, but I also think that HN generally underestimates the social angst over the massive invasion of privacy by corporations. 90% of my non-tech friends and family have asked me how bad it is and how they can avoid it. Of course I just shrug and say you can't...

p.s. can you please link the HN discussion you referenced?
I assure you, you are not.

You are ready to try, and good on ya. But this is going to be harder than you think it is.
I genuinely don't understand this perspective of privacy. I think it's a dishonest use of the word.

For example, in Bluesky, which users you blocked is public information.

To me, this sounds like a bigger "privacy" issue than "the ad company figured out you're a man who lives near the beach so you get ads about surfboards."

Privacy is about control of your data. Control requires centralization. How come people think decentralization is good for privacy? This is a very narrow definition of privacy that doesn't matter for most people.
Obligatory in mice, right?
maybe they could just make the software not be completely shit instead ?

why does Windows take 2 minutes to decide what updates to install, then 45 minutes to install them when Debian on the same machine can do both in under 30 seconds?
You are sounding a bit demeaning. Do you really think people are only capable of caring about one issue?

Regardless, immigration can harm the poor by having increased competition for low paying jobs. Bernie Sanders called open borders a Koch brothers plan to get cheap labor.

This is especially true of illegal immigration since they will naturally be paid less because there is a legal risk.
The original wording confuses because it can easily be interpreted in the passive sense.
So now they need my personal info to make hamburgers???
You're describing the sort of daydreams I had about running a cable between my home and my friend's home when I was 14 years old. We were too far apart. But playing Descent matches would have been awesome. We got by on dialup, but a kid can dream.

I also dreamt of ISDN. Looking back, it seems such a paltry offering, but that tells you what an old man I've become.
I fully concur with the top comment on the article page:

> This is super cool. [...] However, I'd like to slap the Youtuber that decided to record in portrait rather than landscape - especially as this device is rather obviously horizontal rather than vertical.
There is some truth to this crippling power and I don’t doubt that there are examples of it. But social media has been the vector for massive amounts of propaganda. Sorry to say I’d rather just have the commercialized editorial boards. At least that’s a single problem that can be reigned in. Instead we have the worst of both worlds - commercialized media plus a million-headed hydra spewing falsehoods and nonsense.
In Ireland most musicians I know play as a hobby or side-gig and make their money from a non-related day job. The ones who earn enough money from music are those who perform in wedding bands and for those who find that to be too soul-destroying: teaching
Animals could well use an autoregressive model to predict the outcomes of their actions on their perceptions. It's not like we run math in out everyday actions (it would take too long).

Perhaps thats why we can easily communicate those predictions as words

I don't think getting so emotionally charged about these things is a useful approach. Personally, I'm glad to have a good understanding of what made so many people vote this way (even if I very strongly disagree with their fundamental approach and philosophy and behavior).
When I was a windows user 20 years ago I was using scite, the Scintilla demo editor. It had the lightness and simpleness of notepad with syntax highlighting.
The fact that anime & JAV can be blamed is an outlier behavior, China had been investing a lot in anime-game directions but so far don't seem like they're on track to be as dominant as Japan is; there hasn't been significant CAV/TwAV/KAV/PhAV/VAV movement yet(partly because "blurred porn is not porn" defense isn't valid in most Asian countries?)

I'd note that some of Chinese(including Taiwanese) fringe content do seem to resemble that of Japanese ones from couples of decades ago, so there is possibility that this apparent anomaly is just phase errors. Or not, we'll see...
Cost. Ballparking from memory (because I'm on mobile) sending something to space on the Space Shuttle cost something like $40k/kg. The Falcon brought that down to 2500, and the Falcon Heavy down to just over $1k/kg.

So nearly two orders of magnitude cheaper, but you still can't really do anything too fun in space at $1k/kg. The goal with Starship (and its rapid reuse) is to bring costs down another couple of orders of magnitude to where we could eventually even see costs drop into the single digit per kg.

And at that point suddenly space becomes open to things that sound difficult to even fantasize about today, like colonizing Mars, taking suborbital flights to get from Texas to Hong Kong, or setting up industrial systems on the Moon, to say nothing of space tourism that doesn't start with the prerequisite of being a billionaire.

While we can debate the merits of that and people have strong feelings on that, even that would not be a sign of our democracy's failure. It would be a sign that we are culturally swinging back on the pendulum... about 16 years to Obama's first term. Obama was vocally against legalization in 2008.

That's not the end of the world, an Iranian revolution, a sign the pendulum of democracy is broken, or a reason to panic that it won't come back in the future. Democracy has never been, and is not required to be, the overly simplistic view of a straight line.

For the record, even if I disagree with Trump, he would not be a fascist for holding the 2008 position of Obama, any more than Obama was a fascist at the time. And he doesn't even hold that position - Trump is not running on restricting gay marriage. Even if his judges did, to call them fascist for stepping back a decade and a half, just waters-down the term fascist.
A bit off topic:

I wish there was a way for HNers to share Kickstarter campaigns that they are excited about. This is one I never heard about, but may have considered for my car/Hot Wheel enthusiast son.

I know we can obviously just post the link, but seems like that would be considered a promotion (possibly against guidelines) more than just sharing something that HN might enjoy/discuss.

I’m not a huge KS backer (mostly have backed the occasional board game), but I’m sure there’s some pretty cool niche tech that would at least be interesting to hear about, and hear others discuss.
The decision on the title was already made - in the source. Unless the source violated HN guidelines, its title should be kept as is and not "improved".
Not from Russia, but nearby.. It was very common - kinda wild east and nobody cared. As soon our telecom started providing DSL - we (neighbourhood kids) got a commercial DSL into my apartment and shared it between 2 five story apartment buildings. Our set up was tiny and not very reliable. Some local networks like this grew and became almost proper internet providers. But they continued this gray practice of pulling cables in the air, between buildings. They'd also do other sketchy stuff like installing hubs/switches into electrical boxes and tapping supply from the building. We learned about it when a technician from a provider like this dropped a screwdriver on live wires and knocked out power for half of the building.
Yeah, one of the things that makes disasters impossible in the US is that we have real Professional Engineers with Iron Rings doing everything. If you don’t have an iron ring, you can’t really understand what it takes to build a thing in the real world. You can play with your software or whatever but you’re not going to reliably change the real world.

Even Ghost Ship had no iron rings present. That’s what got them. You need those rings. One of my friends has one on each finger. A true 10x Professional Engineer. Nothing he has ever built has a single flaw.
"causes heat"

Heat is the transfer of energy due to a temperature differential. I think you may want to review the highschool physics textbook.
Having the "last mile" be owned by the community just makes complete sense; in fact it should be a requirement of future government subsidies (perhaps with an option for the existing infrastructure, if "good enough - fiber" to be sold to the community) as it reduces overlap and waste.

Around here we have had THREE separate companies drop fiber in the last year (technically not to everyone's house as they only do that last connection when you subscribe) - so my yard now has five fiber lines through it. That's a bit overkill.

They could have had the municipal electric utility run fiber to everyone, and then designate a single building as a POP/exchange and let any company that wanted to run a fat pipe to that and start reselling.

Yeah but we can already launch rockets. Everything else you’re telling me is not application of it but promises that something will come from it. But not listing anything valuable to my average earth dweller life doesn’t tell me that anything beneficial will come from it. No matter how many times someone insists that “yes there will be many advancements obviously, we just need cheaper rockets to tell you what they are first”.

You have to acknowledge that we could also spend a bunch of money and time doing this to no benefit at all for the average earth dweller.

I like the positive attitudes about it but the whole “this’ll be good in the long run, you’ll see” talk is just talk.

It was beneficial previously when we had 0 rockets and 0 sattelites, that was easy to see. Now that we have it, it’s just an R&D playground for the rich and those willing to invest in the dellusion.
Eh, Cargo/Crew Dragon is wildly cheaper than the non-functional Boeing option, and I suspect cheaper (both in cash, and geopolitically) than using Soyuz.

They've taken the lion's share of the market by being quite a bit cheaper. It makes plenty of sense to keep the price there and put the resulting profits into R&D.
Could this also be used for manufacturing lots of other microscopic things? layer by layer?

"Instead, their method finds errors up to 0.017 nm along side-to-side measures (x and y axes) and 0.134 nm when assessing the distance between the two chips (z-axis)."

Could you make some very very sensitive and tiny seismic sensors with this?

edit:
"
Arbabi also points out that this method can be used to make displacement sensors that can be used for measuring displacements and other quantities. "Many physical quantities that you want to detect can be translated to displacements, and the only thing you need is a simple laser and a camera," he says.

For instance, "if you want a pressure sensor, you could measure the movement of a membrane." Anything that involves movement—vibration, heat, acceleration—can in theory be tracked by this method.

I've recently looked at the suite of protocols underlying RCS (or so at least I think; the standards landscape is as confusing as ever), and it's baffling how the industry ended up with that when XMPP was... just there.

The contortions they had to do to cram server-based federated instant messaging into the context of the SIP protocol stack by sheer force are something to behold.

I can only assume this is entirely by design – the more needless complexity, the more opportunity to patent things (or at least keep competitors out): As far as I understand it, practically all carriers are just outsourcing the entire thing to Google.
By that logic even dollar value is made up. And profit in dollars too.

Market cap should be equal to the expected discounted profit.
I haven't been to any of the ones in London but I like scrolling through https://lu.ma to look for tech events.
18 seems terrible. You're making a fraction of the kids miss out on their friends' lives just before they're about to go their separate ways and potentially never see each other again. At least give them a bit of time to naturally settle into the new social environment before they permanently part ways?
I think the idealism here is attributed to their employees, not the leaders. A pretty good chunk of BigTech employees were not on board with the boss' politics when I worked there, and it caused a lot of morale/retention issues when leaders made overt rightward moves like this.
