The order returned from the Index Scan is not the ordering requested by the user, so there would still have to be a full (or topk) Sort over the dataset returned from the index scan, which could negate the gains you get from using an Index Scan; PostgreSQL itself does not produce merge join plans that merge a spread of index scans to get suffix-ordered data out of an index.

Donald Trump has tried to overthrow an election once already -- first through conspiracy, then through violence. The fact that he's not rotting in a prison cell is largely due to corruption of the judiciary (Aileen Cannon).

Ask HN: What AI content automation stack are you using in 2026?
by jackcofounder | 2026-03-10 10:06:19+00:00
After 5 years of building SaaS and testing AI content workflows, here's what the landscape looks like in 2026:

*What the data actually shows:*
- AI-integrated SaaS grew 40% YoY, but thin AI content gets penalized (Google's 2025 update)
- Companies using AI publish 3.2x more content, but cost per article dropped from $157 to $12-18
- The bottleneck shifted from writing (AI handles this) to idea generation (still hard)

*What's actually working:*
- Semi-automated ideation → AI research → LLM drafting with brand fine-tuning → Human editing → Auto-scheduling
- Automate 70%, but that 30% human touch is non-negotiable for anything that matters

*The honest breakdown:*
AI excels at: Blog drafts, social scheduling, email personalization, video repurposing
Still needs humans: Brand storytelling, complex sales, community management, crisis comms

*My minimal working stack (<$200/mo):*
- ChatGPT/Claude Pro ($20) + SurferSEO ($89)
- Native APIs + Buffer free tier
- Google Analytics + Search Console

The differentiator in 2026 isn't access to GPT-4 (we all have that). It's orchestration, brand fine-tuning, and knowing where/when to inject human judgment.

*Questions for the HN crowd:*
- What's your actual content automation stack?
- Where are you seeing real ROI vs. hype?
- What's still broken in 2026?

Curious to hear what's working in production vs. what's still just demoware.

That may be true in many places, but the Swedish forestry industry is very big, and the district heating plants really do burn mostly forestry byproducts. Of all the biofuel used in Sweden (not just for energy generation), 75% comes from forestry products, and the vast majority of it is either unrefined wood products or byproducts from Kraft process paper manufacturing (like tall oil and turpentine etc).

Specifically in district heating, 87% of the forestry-sourced fuel is unrefined wood products. Almost half of it is just bark, branches and treetops. Of all the biomass in an average mature tree logged in Sweden, 43% ends up as pulpwood, 43% as saw timber, 8% gets burned for fuel and the remaining 6% is treetops and branches which also tend to end up burned for fuel.

There is definitely a lot of debate in Sweden about sustainable forestry practices, though. The industry really wants to clearcut everything for convenience, but it's really bad for biodiversity and the general public hates it.

Source: the report Hållbarare biobränsle i fjärrvärmesektorn, Energiforsk 2023; specifically the charts on pages 14 and 15. Link: https://energiforsk.se/media/33316/2023-979-ha-llbarare-biob...

Addendum: I believe there's also been some studies and experiments involving importing olive pits from the Mediterranean olive oil industry for burning in district heating plants, but I don't think it's been done at scale.

Yann LeCun said a number of things that are very dubious, like autoregressive LLMs are a dead end, LLMs do not have an internal world model, and this morning https://www.youtube.com/watch?v=AFi1TPiB058 (in french) that an IA cannot find a strategy to preserve itself against the will of its creator.

As a french, I wish him good luck anyway, I'm all for exploring different avenues of achieving AGI.

How is this related to the inference, may I ask? Except for some very hardware-specific optimizations of model architecture, there's nothing to prevent one to host these models on your own infrastructure. And that's what actually many OpenRouter providers, at least some of which are based in US, are doing. Because most of Chinese models mentioned here are open-weight (except for Qwen who has one proprietary "Max" model), and literally anyone can host them, not just someone from China. So it just doesn't really matter.

For well-intended open source contributions using GenAI, my current rules of thumb are:

* Prefer an issue over a PR (after iterating on the issue, either you or the maintainer can use it as a prompt)

* Only open a PR if the review effort is less than the implementation effort.

Whether the latter is feasible depends on the project, but in one of the projects I'm involved in it's fairly obvious: it's a package manager where the work is typically verifying dependencies and constraints; links to upstream commits etc are a great shortcut for reviewers.

libstdc++'s <print> is very heavy, reflection or not. AFAIK there is no inherent reason for it to be that heavy, fmtlib compiles faster.

<meta> is another question, it depends on string_view, vector, and possibly other parts. Maybe it's possible to make it leaner with more selective internal deps.

At the moment verification at scale is an unsolved problem, though. As mentioned, I think this will act as a rough filter for now, but probably not work forever - and denying contributions from non-vetted contributors will likely end up being the new default.

Once outside contributions are rejected by default, the maintainers can of course choose whether or not to use LLMs or not.

I do think that it is a misconception that OSS software needs to "viable". OSS maintainers can have many motivations to build something, and just shipping a product might not be at the top of that list at all, and they certainly don't have that obligation. Personally, I use OSS as a way to build and design software with a level of gold plating that is not possible in most work settings, for the feeling that _I_ built something, and the pure joy of coding - using LLMs to write code would work directly against those goals. Whether LLMs are essential in more competitive environments is also something that there are mixed opinions on, but in those cases being dogmatic is certainly more risky.

Lmao why. Stop driving through red light, stop speeding. Ya fuckers.

In the UK it's ridiculous, barely any speed cameras and those that are there are clearly marked (legally have to be). Everyone just slows down for the speed cameras and then start speeding again after.

I've actually heard people say that the above is effective because it makes people slow down where it's important. Or, you know how about people just don't fucken speed in general?

If it were up to me they'd be everywhere, totally unmarked and all revenue from fines would go to charitable causes to rule out the "but they just do it for da money!11" bs - no, they're doing it to stop people speeding and killing someone for fuck's sake.

Stop speeding.

Astronomers do not need leap seconds, because even with this adjustment UTC cannot be used to determine anything in astronomy.

Astronomers need either true time, which is TAI, to be used in computing the positions of celestial bodies, and they need for observations the so-called Sidereal Time, which is not a time but the angle between a coordinate system attached to the Earth and an inertial system of coordinates attached to distant celestial objects that have negligible angular movement (in the past those were distant stars, now they are distant galaxies or quasars).

The Sidereal Time can be computed in a complex way from TAI, because it is determined by the periodic rotation and precession of the Earth and by various superposed periodic or random movements.

The UTC is not adjusted to match the current true rotation angle of the Earth, which you can measure by looking up to the stars, but it is adjusted to match within 1 second a fictitious angle that would be the rotation angle of the Earth-Sun direction corresponding to an Earth that would rotate uniformly both around itself and around the Sun, so that the duration of a day would have been constant.

In reality, the duration of a Solar day, i.e. the time between 2 consecutive noons, varies a lot during the year, by a large fraction of an hour (by about a half of hour peak-to-peak), so using UTC directly for estimating the position of the Sun gives a very big error, of many minutes of hour.

So what you need for astronomy is to know the current TAI and you need a Sidereal Time calculator, which you need for knowing in what direction to point your telescope, to find a given celestial object.

UTC cannot be used directly in astronomy, but only after passing either explicitly or implicitly through TAI. The fact that astronomical almanacs are published using UTC in their tables is obfuscating this, because the values in the tables have not been computed using UTC, but everything has been converted to UTC to match the time that is presumably shown by the watch or clock that the almanac user may have.

Definitely, but that's kind of my point: the maintainers are still going to be way better at all of that than some random contributor who just wants a feature, vibe codes it, and barely tests it. The maintainers already know the codebase, they understand the implications of changes, and they can write much better plans for the agent to follow, which they can verify against. Having a great plan written down that you can verify against drastically lowers the risk of LLM-generated code

I understand. The reason why I asked is that I have had a similarly used non-cooling glass pitcher. If I don't wash it from the inside, then after a few months it develops an invisible microbial slime layer inside which is not healthy. I can feel this layer by running my finger on the surface. Scrubbing and soap is required to eliminate the slime fully, preferably done once a month.

I understand that the pot cannot be brushed. Using dish soap also may not make sense because it then takes a lot of water to fully rinse away the soap. When you run your finger on the inside, does it feel slimy at all?

With a water bottle, the slime layer forms within weeks, not months, although a water bottle is different because it does touch the mouth. It is necessary to scrub and clean the water bottle every week from the inside, ideally with soap.

The multi-file coherence problem that matrixgard points to is the central unsolved challenge in vibe coding platforms. Single-file generation is impressive; maintaining coherent state across a growing project as it diverges from the original context is where most tools break down.

Your approach of reasoning over the existing codebase rather than regenerating is the right architectural instinct. The question is how well you can maintain that context as the project grows in complexity — especially with state management, where the implicit coupling between components tends to multiply.

On the mobile-first question: I think it makes sense for a certain class of projects (simple CRUD tools, internal utilities, one-off automation). For anything with real architectural complexity, you still need the full feedback loop of running locally, testing against real edge cases, and iterating with the kind of depth you can only get at a desktop. That's not a knock on the concept — it's a scope definition.

The Agile Vibe Coding Manifesto (https://agilevibecoding.org) has a principle that feels relevant here: "Code structure reflects the domain — organized around domain concepts rather than technical convenience." Building that structural clarity from a mobile prompt session is the hardest part to get right.

The AR push is also an issue in itself. There are very fundamental issues that remain unresolved, and I would say untackled even.

VR setups make you isolated and vulnerable. Any VR device is really awkward to use in public (read: in your living room or in an office).

In turn, AR setups that let the world through reduce image quality by virtue of being transparent, and it is unclear that they provide advantages. You get a slightly more immediate access to notifications in return for permanently pointing a camera towards anything you look at, which is understandably not well received.

And that's just for content consumption. When you introduce work, input is still significantly worse unless you're sitting in front of a keyboard and mouse, in which case you might as well have a full laptop.

One pattern I keep noticing when analyzing landing pages:

High bounce rates often come from subtle trust gaps rather than obvious UX issues.

Examples I see a lot:

• weak credibility signals above the fold
• unclear product positioning
• pricing hesitation
• cognitive overload in hero sections

Traditional analytics show the bounce rate but don't really reveal which psychological factor caused it.

Curious how other founders here approach diagnosing this.

Newer process nodes are not the main avenue of improvement. What those transistors are used for is more important and it’s plausible that improvements between generations can increase performance by multiples on a specific task. All of the improvements aren’t necessarily in the chip itself either.

E.g. the next gen might have hardware inference for lower bits, more memory bandwidth, etc.
by eyk19 | 2026-03-10 10:12:36+00:00
The point isn't that agent output is magically better; it's that reviewing your own agent's output is way cheaper (intellectually) than reviewing a stranger's, because you've written the plan by yourself. And 'slop' is mostly what you get when you don't have a clear plan to verify against. Maintainers writing detailed specs for their own agents is a very different thing from someone vibe coding a feature request

Monopoly isn't the only thing that allows you to charge large margins.

API inference access is naturally a lot more costly to provide compared to Chat UI and Claude Code, as there is a lot more load to handle with less latency. In the products they can just smooth over load curves by handling some of the requests slower (which the majority of users in a background Code session won't even notice).

USA is also kind of "all-in" at this point.

People say that Trump should TACO but at this point it's basically lighting the Gulf States' relationship with the US on fire. At a minimum, they will have to massively hike their own defense expenditures and likely reorient money earmarked for investments in the US to do that.

I felt this was why math textbooks pose open problems without mentioning them as such. I feel Karatsuba for example was able to come up with his multiplication scheme because he wasn't aware a mathematician had written a false result proving impossibility of faster than quadratic time multiplication.

Or more concretely that famous story where a student had solved certain open problems in statistics thinking they were homework problems.

>This 14-country operation demonstrates the extraordinary cooperation with our international partners

The way they are treating their "international partners" would make this kind of cooperation very dificult on the future, and given that any dismantled site will give origin to new ones to fill the void, seems to me that it does more harm than good. A known evil is easier to dodge than an unknown one.
Gemini Exporter – a Chrome extension to export Gemini chats
by nongquy | 2026-03-10 10:16:05+00:00
Hi HN — I built Gemini Exporter, a Chrome extension for exporting Gemini conversations.

I made it because I wanted a simpler way to save useful Gemini outputs outside the browser for writing, documentation, and reuse later.

You can try it here:

- Chrome extension: https://chromewebstore.google.com/detail/gemini-exporter-save-gemi/lgipeakgdkcgnkdljeagconfbfeolidj

- Website: https://backrun.co/gemini-exporter

I’d especially love feedback on which export formats are actually useful and where the workflow still feels rough in real use.

Thanks for taking a look.

China is producing 7nm chips and working on 5nm. The lead has shrunk to be almost insignificant.

People on internet forums are obsessed over "bleeding edge" fabs, when the vast majority of semiconductor products are designed for a specific process and kept in production for at least a decade.

If beating Taiwan is your definition of "catching up", then you're basically making China's status as a legitimate semiconductor manufacturer contingent on the obsolescence of everyone else's status. That's not very fair and it's not even something to brag about. Once you lose the grin, it would be game over for you.

I hope they don’t ever do a touchscreen MacBook. They already have every angle of that use case covered far better than the competition; either you get an iPad if you absolutely need to be pawing at a screen, or you have the excellent trackpads that are far and away par excellence. I don’t see how a touch screen on top of also the industry standard for screen quality will in any way improve by having greasy finger trails distorting the tiny pixels.

Maybe I’m missing something. How would a touchscreen MacBook improve on something?

That being said, based on what I’ve been seeing at Apple, I would not be surprised if they did go down that mediocrity route.

> I understand that women are often harassed, but the law already has a process for dealing with harassment.

And that would be a good argument if we could see that the process really is used and trusted. Do we? What I see is the opposite; the ubers and bolts of this world only care as much they have to. So what is probably happening is that uber calculates this will be cheaper than dealing with the consequences of women losing trust and stopping using their services. If this is banned by the courts, they will move on to the next cheapest solution and so on.

What would interest me is, what would be a proper solution to this issue? Apart from Waymo, probably a surveillance/recording of all the interactions between the customer and the driver?

Good timing on this. I just finished testing PromptGuard last week — similar product, same 95%+ detection claim, multi-encoding detection highlighted. Found 12 of 18 attack vectors bypassed: base64, unicode homoglyphs, ROT13, leetspeak, reversed text, non-English inputs, multi-turn fragmentation.

InferShield makes the same encoding claims. Sent a note to security@infershield.io today offering to run the same test suite. No pressure — just documenting the attempt publicly.

If the team is watching this thread: the session-history tracking for multi-turn attacks is genuinely differentiated. That is harder to bypass than single-shot encoding filters. Worth stress-testing that specific path.

Recently, what have been working for me is to take a day off just to explore stuff that interests me related to programming. I've been learning sleep states and working on the Rust track on Exercism.

The productivity boost that you get from Claude Code should be reinvested into learning your subject area deeper, rather than just churning out more superficial code.

It makes me happier this way. Experiencing flow is the best way for me to feel happy, and programming was the most reliable way to achieve that before Claude Code / Codex.

Why world model? To emulate how we became sentient?

A "world" is just senses. In a way the context is one sense. A digital only world is still a world.

I think more success is in a model having high level needs and aspirations that are borne from lower level needs. Model architecture also needs to shift to multiple autonomous systems that interact, in the same ways our brains work - there's a lot under the surface inside our heads, it's not just "us" in there.

We only interact with our environment because of our low level needs, which are primarily: food, water. Secondary: mating. Tertiary: social/tribal credit (which can enable food, water and mating).

Okay, but you're celebrating make-believe virtues. Iceland is also not destroying its tropical coral reefs. That sounds nice...but it has none. Nor any sort of tradition or incentive to try doing that.

The US coal thing is all about widespread memories (and myths) of sustained good economic times, in large areas of the country which now feel destitute. Millions of voters feeling that they have no future. If not that the elites want them to hurry up and die.

To paraphrase Munger - if you want different outcomes there, then you need to change the incentives.

That was a fun read, and it might even explain why a lot of Gen-z is opting out of any sort of career building, wanting values instead (or next to) a paycheck. They saw their parents do The Office in real life.

Most of the world is perfectly fine with 12:00 not being synchronized with high noon [0]. And some jurisdictions still semiannually f*k with it further using DST. Generously assuming the current time keeping system will survive for ~6k years (looking at the leap seconds accumulation rate for the last 50 years) we can just shift timezones by one hour.
