> maintenance_work_mem begs to differ.

HNSW indices are big. Let's suppose I have an HNSW index which fits in a few hundred gigabytes of memory, or perhaps a few terabytes. How do I reasonably rebuild this using maintenance_work_mem? Double the size of my database for a week? What about the knock-on impacts on the performance for the rest of my database-stuff - presumably I'm relying on this memory for shared_buffers and caching? This seems like the type of workload that is being discussed here, not a toy 20GB index or something.

> You use REINDEX CONCURRENTLY.

Even with a bunch of worker processes, how do I do this within a reasonable timeframe?

> How do you think a B+tree gets updated?

Sure, the computational complexity of insertion into an HNSW index is sublinear, the constant factors are significant and do actually add up. That being said, I do find this the weakest of the author's arguments.

All kinds of self-published stuff, lots of which later became commercial. You will have heard of some of it, for sure. Darude - Sandstorm? That was from there. DragonForce were big in the power metal category. The band that became Linkin Park came from there. And then hundreds of thousands of indie artists (including an earlier me).

The RIAA's action there destroyed vast amounts of music, pretty much the equivalent of if someone just aggressively deleted Bandcamp and Soundcloud put together and everything on it because they were upset they didn't control it all. I will never forgive them for that.

Maybe for you! That's your call. I'm also interested in my career.

I've had 3 Elixir jobs and 2 Rust jobs in the last 10 years. All were on real products, not vaporware. I learned a ton, worked with great people, and made real friends doing it.

Luck? Skill? Who knows. It's not impossible to work with the technology of your choice on problems you find interesting if you're a little intentional.

Nothing ever gets better if everybody just does what's already popular.

Maybe not the most expensive but it is certainly potentially one of the most costly. Look at Facebook with PHP and Dropbox with Python. It's the sort of thing you can overcome despite the odds (as both those companies did), but can also tip an on-the-edge company into failure.

Same thing with the fundamental architecture of programs, and especially the data model & database solution.

Still I don't entirely agree with the article. He makes it sound like there isn't any difference between programming languages and any preference is purely about developer identity. But that identity doesn't come from nowhere. Rust is popular because a load of C++ developers finally found something technically better. Not because they all woke up one morning and decided to be "a Rust developer".

Where the story falls apart is that Perl is arguably even worse than PHP. One deluded Perl programmer does not prove a principle.

On Rust vs Go, he's absolutely right that Go is has a slightly better "build & deploy" story (though not by a much). But reading between the lines I think he's misrepresenting that - it sounds like a) that was just one point for choosing Rust, and b) that was a point when comparing to typical alternatives, e.g. C++ or Java. It's not untrue that Rust is easy to build & deploy simply because Go is slightly easier.

The interesting thing about DMT is that it’s an ego-stripper. You have no sense of self. You are non-corporeal. Time and space are irrelevant.

People who have taken DMT find it very difficult to explain what the visions mean when they flash before your eyes. “Flash” in the sense that they are so fast and from every conceivable direction simultaneously and you can see in all directions. And beautifully purple.

Since we are beings that have a conscious “self”, we attribute these moving images to “our lives flashing before our eyes”, but I believe that to be our egotistical selves applying that after the fact.

I now believe that the human brain acts as a filter to a raw stream of collective human shared consciousness, normally out of our grasp.

What people see there is a short temporary window into everyone else’s exact same moment in time.

It’s like a back door hack into god’s admin console and you get to watch the interconnected consciousness of human existence in real time for a few minutes.

However our brains aren’t meant to run unfiltered. Our brains usually optimize and filter as much as they can to conserve energy. We notice the differences and not the usual. Our brains fill in gaps. Eventually the brain overloads as the trip runs to an end and everything goes black. A complete void overwhelms you.

The brain finally reboots and coming back is like watching an old Linux machine reboot, loading its kernel and drivers before adding the OS layers.

First you question what you are, before then discovering who you are. It’s like a process of birth but coming out of hibernation mode for fast boot.

Maybe death is the same. Returning to the collective consciousness.

Like the ant that cannot comprehend the existence of the universe or the neuron that only understands its nearest neighbors, maybe there exists a plane above human individuals as an analogy to the neuron or the ant, that we too cannot not perceive nor understand, because our brains are too small to comprehend it. Only for those fleeting moments when we overclock the system.
Ask HN: What Is the State of Mobile Development in 2025?
by sarimkx | 2025-11-03 22:43:51+00:00
Ever since AI has become a thing, there is very little talk of mobile development.

Anything interesting in this space? What is currently trending in the mobile/app dev space? Languages/frameworks being used? How has mobile/app development evolved recently? What is your day to day work like now if you're focused purely on mobile/app dev. Career/work prospects?

You can also be eco-system specific e.g. Android/iOS

It’s confusing, but those tunnels are not designed to be used directly - you’re supposed to use them as an origin in a DNS record or hit them from a worker. The IPv6 address you’re getting there is actually a private (ULA) address and will not be reachable via the internet. I’m not sure why they return it at all.

Before I got my first full time software engineering gig (I had worked part time briefly years prior) I was working full time as a carpenter. We were paying for an expensive online work order system. Having some previous experience writing software for music in college and a couple /brief/ LAMP stack freelance jobs after college I decided to try to write my own work order system. It took me like a month and it would never have never scaled, was really ugly, and had the absolute minimum number of features. I could never had accepted money from someone to use it but it did what we needed and we ran with it for several years after that.

I was only able to do this because I had some prior programming experience but I would imagine that if AI coding tools get a bit better they would enable a larger cohort of people to build a personal tool like I did.

I quite liked FreePascal and thought that Lazarus makes the experience even more palatable. Stuff like this is really good for cross platform GUIs without having to shove a whole browser in there: https://en.wikipedia.org/wiki/Lazarus_Component_Library Oh and the compiler is pleasantly fast and the language feels a bit easier to work with than C++ and the whole RAD approach in general for GUI software in particular is something that I yearn for more of.

At the same time, even modern Pascal dialects seem niche and the communities and libraries aren't quite there, especially when it comes to the ease of doing something like webdev: mORMot exists but will never be as popular and deeply integrated with everything like something like Spring Boot https://github.com/synopse/mORMot2

That said, there are also some cool projects out there, for example, a whole game engine: https://castle-engine.io/

I'm especially mentioning that, because the dev actually did a nice writeup on Pascal: https://castle-engine.io/modern_pascal

There's also a list of some software using Pascal: https://wiki.freepascal.org/Projects_using_Free_Pascal and sometimes it's packages that you might not immediately think of, like PeaZip which is a nice little program: https://github.com/peazip/PeaZip

I will also say that the idea of having a community Wiki for the programming language and the projects around it seems really nice: https://wiki.freepascal.org/ Maybe not possible for super widespread languages, but for someone taking a look around this is really, really nice.

I'm not sure we can look forward to self-hosted models ever being mainstream.

Like 50% of internet users are already interacting with one of these daily.

You usually only change your habit when something is substantially better.

I don't know how free versions are going to be smaller, run on commodity hardware, take up trivial space and ram etc, AND be substantially better

It is increasingly trendy for grocery stores in America to have a "fancy cheese" section because the unit cost (eg dollar-per-ounce) of cheese makes it profitable. I'm guessing Europeans are paying high unit cost too, but don't mind because it's more socially engrained to seek out "quality" foods like fancy cheese.

In the USA, cheese is either a salad topping, a sandwich/burger topping, or a pizza topping, and not much else. I once bought some pecorino romano to make cacio-e-pepe and regret doing that, it's an overhyped dish.

Looking for security engineer roles. For the past 5 years I have been building security tooling that internal teams can make use of. I work closely with other teams to help improve the security posture of their apps. I help write documentation and host department wide presentations to educate others about web app security and steps they can take to make apps more secure. I took on the responsibility of managing our H1 Bug Bounty Program which previously was failing SLA targets by 10+ months and managed to bring it down to days. I have helped mentor interns and junior developer and also been active in conducting pair programming interviews for future candidates. What you get from me is a go-getter, self-motivated individual. I am always looking to improve not only myself but also my work.

Spark a debate about ways to (in light of the coming wave of cheap machine labour that would outcompete human on most fields within few years, thus tanking the current societal organisation) switch to a post-commercial open-access open-source commons-based post-scarcity economy! Switching from profit/cost to quality/joy as prime optimization targets and readjusting focus to build planetary infrastructure instead of upping shareholder value.. Chances are the majority of people is fed up with the money system and a campaign for "commons economy 2030" can go viral. So we an seize the moment – or wait and see others do it, to their advantage.

We host thousands of forums but each one has its own database, which means we get a sort of free sharding of the data where each instance has less than a million topics on average.

I can totally see that at a trillion scale for a single shard you want a specialized dedicated service, but that is also true for most things in tech when you get to the extreme scale .

Hi,

I have over 20 years in the industry starting out as a Linux SysAdmin / Network Engineer and now doing more Systems / Low level Programming, R&D, and occasional DevOps.

Looking for opportunities involving low level / embedded systems / backend software development. Happy to also do automation / SysAdmin / DevOps as well. Although not my forte, I like to do robust automated testing / QA for software to ensure they meet (potentially undocumented) requirements.

Maybe it's better now, but when I started my time on OSX, the built in terminal defaulted to "unlimited" scrollback, so if you were used to tailing giant log files, it would beachball pretty quick. I spent the rest of my time using iterm2 instead; it defaulted to a sensible scrollback length; and at some point it added a progress bar when you made a giant paste.

- new user sign up - new subscriptions - enlengthened subscriptions - mails send - overall interactions - testing of new marketing campaigns/channels (they do massive MVT, even fontsize&coloring)

just to make that clear: churn is tracked/written down for sure, but its not debated in a context of "is churn growing if more people are matching successful" - because in 99.9% of all cases people do not meet successful, so this metric is irrelevant

> I look forward to the "personal computing" period, with small models distributed everywhere...

Like the web, which worked out great?

Our Internet is largely centralized platforms. Built on technology controlled by trillion dollar titans.

Google somehow got the lion share of browser usage and is now dictating the direction of web tech, including the removal of adblock. The URL bar defaults to Google search, where the top results are paid ads.

Your typical everyday person uses their default, locked down iPhone or Android to consume Google or Apple platform products. They then communicate with their friends over Meta platforms, Reddit, or Discord.

The decentralized web could never outrun money. It's difficult to out-engineer hundreds of thousands of the most talented, most highly paid engineers that are working to create these silos.

I doubt it, because my definition implies that consciousness is not that interesting. It's just the feeling of self-awareness, which can be independent of actual self awareness.

If you have a phantom limb, you feel "conscious" of the extra limb even if it's not a real demonstration of self-awareness.

Animal Intelligence is an emergent phenomena resulting from many neurons coordinating. Conciousness is the feeling that all of those subsystems working together as a single thing, even if they aren't

> To be completely clear, it’s not on the “IMMEDIATE” roadmap (as noted in the prior comment). It’s absolutely on the roadmap and I even already started some it in a branch. But as a passion project, we prioritize working on whatever we want and this isn’t currently the priority. It’s high on the list but not like.. next release (“immediate”) priority at the time of this comment.

I think GPT 5 is pretty good. My use case is vscode copilot and the GPT 5 Codex model and the 5 mini model are a lot better than 4.1. o4 mini was pretty good too.

One of the big ones that hasn't been mentioned is all of a hexagon's neighbors are equidistant. As a result, h3 is a better fit for flow modeling - stuff like telematics. This has some nice properties for ML too.

It's not "quibbling" to correct your mischaracterization of the truth.

If you'll forgive me borrowing your logic: "I'm not saying that people should eat beef, but many people do eat beef, so it's worth comparing which beef sources are better than others."

Plant-based diets are a very good answer to the problems caused by animal agriculture. If someone takes issue with that answer, I'd need a better reason than their personal pleasure to take them seriously in the conversation.

> IFRS → associates are always related parties (disclosure under IAS 24.9(b)).

Ok, just for the record you started saying that it wasn't so, talking explicitly about what are related parties in IFRS: https://news.ycombinator.com/item?id=45720653

> Under U.S. GAAP (ASC 850), however, the definition is narrower. [...] associates accounted for under the equity method are not automatically treated as related parties unless reciprocal influence or common control exists.

Is that definition written anywhere?

According to the glossary in ASC 850:

"Related parties include: [...] b Entities for which investments in their equity securities would be required, absent the election of the fair value option under the Fair Value Option Subsection of Section 825-10-15, to be accounted for by the equity method by the investing entity"

It says nothing about "reciprocal influence or common control" - only that investments would be required to be accounted for by the equity method. And that's a question of "significant influence".

If Microsoft has "significant influence" on OpenAI (does it?) and is required to account for its investment in OpenAI using the equity method (is it?) then I don't see why it wouldn't be a related party according to ASC 850.

Now, if it doesn't have "significant influence" and is not required to account for its investment using the equity method then it's not an "associate" under IFRS either.

So it seems that if it's an IAS 24 related party it's also an ASC 850 related party. (At least until you provide some evidence for those reciprocal influence requirements you mention.)

The article says the "super pumper" could supply 8,800 gallons per minute, and it came with three "satellite trucks [...] not burdened with a pump of their own"

Your basic modern fire pump unit can pump 2,200 gallons per minute (if you can find a water source that'll give you that much) and it'd typically have a crew of 4-5 firefighters on board.

So you'd probably replace it with 4 regular fire trucks? Then you've got just as much pump capacity, plus you've got the flexibility to send the trucks to different places.

R2’s writes are much slower than S3/GCS. It’s not a good fit unless your workload does many reads for each write (e.g. assets). Also it is notably not multi-region - it just picks a region automatically based on where you created the bucket from.

KV is super expensive - once you’re operating at non-trivial scale, reading another configuration value per-request in your worker starts to cost thousands per month. KV’s tail latencies are also surprisingly bad (I’ve seen over a minute), even for frequently read keys that should be easily cached.

You make some interesting points, but:

> Similarly, if we can compute consciousness on a chip, then the chip obviously contains that consciousness.

This is like claiming that neurons are conscious, which as far as we can tell, they are not. For all you know, it is the algorithm that could be conscious. Or some interplay between the algorithm and the substrate, OR something else.

Another way to think of it problem: Imagine a massive cluster performing computation that is thought to give rise to consciousness. Is is the cluster that is conscious? Or the individual machines, or the chips, or the algorithm, or something else?

I personally don't think any of these can be conscious, but those that do should explain how they figure these thing out.
