I'm glad the data is being catalogued and made available like this but the interactive map doesn't work for me at all. Seems to be missing clickable zoom controls and gestures on my trackpad only seem to be able to get it to zoom out, not in (I think maybe it's becoming entirely unresponsive when it first registers the zoom in event and dropping the rest of it). Did anyone actually bother to test this on a low end device?

More generally, if you're a webdev with a high end workstation it's really important to occasionally spin up a single core VM with less than 4 GB RAM, open a youtube video, and then check how well your page works in a second simultaneously visible window.

Doesn't show the comparative energy waste of bitcoin?

This source[0] says

> One Bitcoin now requires 854,400 kilowatt-hours of electricity to produce. For comparison, the average U.S. home consumes about 10,500 kWh per year, according to the U.S. Energy Information Administration, April 2025, meaning that mining a single Bitcoin in 2026 uses as much electricity as 81.37 years of residential energy use.

> Where are these mythical people who aren’t concerned with both?

People don't care about "what companies serve them". They only care if the children see sexual content (or things considered deviant). Once sexual and deviant content is filtered, they're happy to give away their children's development to the company's algos.

In effect, the people don't want to concern themselves with what their children consume, unless they're outraged by things normally taboo in their age group. Besides, if everyone is in it "it's not that wrong". They seek reactive entertainment rather than proactive engagement in their children's development.

I feel like the article is conflating simplicity with minimalism. Just doing the minimum of whats asked isn’t in itself enough to differentiate great vs ok.

Simplicity is worth recognizing only when the person started with a complex problem and ended up with a relatively simpler solution.

For a straightforward ask you will have people who will just build a hut and another will build a campus, who is right really depends on many factors and time.

I think stacking windows looks better, makes for a cool screenshot when trying to sell the thing. But tiling windows are more ergonomic for actually using the infernal machine.

For me the revelation was that I have never said "Oh boy I sure am glad this window partially overlaps this other window" I either want one full screen windows or a few windows side by side. Why do I have to handle this myself? and went to the dark side, a tiling window manager. To the point that it really chafes now when I use stacking windows, It feels like I spend most of the time shuffling windows around.

To ease the overlapping window pain many linux window managers have a feature where the focused window does not have to be the top window and this makes things a lot better, you can be looking at the top window and typing/clicking on the partially obscured bottom window.

While Voxile has off-grid blocks of voxels for monsters etc, it is much more serious about being on-grid for everything else. The entire world is entirely on-grid, single size voxels, you can only place aligned objects, and rotate in 4 directions. These voxels only every exist as voxels, never as polygons.

In contrast with most voxel-looking games, which are actually meshes converted from voxel inputs, placed at arbitrary locations with arbitrary scale.

When I started this project, I actually prototyped what it would take to have moving objects in-world as aligned voxels, but the animation was too jerky and it was too limited. Would have been an interesting "style" suitable for some games (strategy games?) but none with fast paced realtime combat.

the part that gets me is "our business is strong, gross profit continues to grow." they didnt fire 4000 people because things were bad. they fired them because things were good enough that AI could handle the rest. thats a fundamentally different kind of layoff and i dont think we have the language for it yet. theres a novel i read recently (the silicon ceiling, jude sterling) where a swiss farmer gets a report telling him to cull his oldest cow because the algorithm says its inefficient. he knows the cow is fine but the spreadsheet says otherwise. thats basically what happened at block except the cows are software engineers. and the spreadsheet was right about the margins.

Beyondcorp protects communication between trusted devices. The work to maintain a trusted hardware device of a particular model is high; CVEs occur constantly and sometimes you have to rely on the vendor to provide microcode (even if you get the source to review, they may be the only ones who can sign it, for example) or drivers.

The network connection isn't the main problem, it's every access to a protected system that would no longer trust the device.

That article is somewhat revisionist.

> In 1945, the heating effect of a high-power microwave beam was independently and accidentally discovered by Percy Spencer

Sure, meanwhile using microwaves to heat stuff up dates back to the 1920’s. WWII soldiers would regularly stand in front microwave equipment to warm up. The resonant-cavity magnetron was a British invention that finally made microwaves far more efficient to produce.

The story about noticing a candy bar melting in his pocket is also kind of funny as that’s what normally happens to candy bars in your pockets, further it means he didn’t notice he himself warming up.

Step back further and see the incredible shareholder value that may be unlocked - potentially trillions of dollars /s

Capitalism has been crushing those at society's fringes for as long as it existed. Laissez-faire regulation == unmuzzled beast that will lock it's jaws on, and rag-doll the defenseless from time to time - but the beast sure can pull that money-plow.

It definitely ignores that many people don't have time. If someone is working over 40 hours per week, plus maybe doing unpaid labor taking care of kids or elders, where are people supposed to find the time and energy to brush up on a million different topics they don't even know they might not know enough about? Especially if they might also have medical issues, or hobbies, or want to have any time at all to relax.

Obviously, one way to improve the situation would be to make sure people are paid fairly and not overworked and have access to good and affordable or free childcare and elder-care and medical care, but corporations don't want that either. If anything, they're incentivised to disempower workers and keep them uninformed, and to get as much time out of them as they can for as little money as possible.

I agree with this. One way that I will go further is to say that “understanding of the whole system“ is a pretty fraught phrase. One person‘s holistic understanding is another person‘s gnostic gobble-de-gook. Realistically, they are all essentially just abstractions bounded by a different stopping rule. Just because one person‘s view of the whole system does not include what the GOOGLE engineer writing the code had for breakfast does not mean that that can’t be reasonably included.

The issue I think people have is that abstractions do not announce when they are insufficient or porous. This means that an abstraction which is perfectly trustworthy without further inspection for many years can suddenly become hazardous without warning.

If you're not selling them then there isn't really any certification requirements until you start to get into the mains voltages. This all seems to be 12/24V DC stuff on the battery side and 60V DC on the solar side which comes under 'extra-low voltage' in basically every jurisdiction which is usually not really regulated because it's difficult to shock someone.

The battery stuff is more risky (bringing lithium cells into the picture) but I don't think anyone should be worried by the MPPTs.

Nice job!

> The mechanism seems to be melody acting as a retrieval cue.

My concern is that one of the significant reasons that the melody aids as a retrieval cue is because that motif is familiar to you.

Take for example the Latin America cover of Bonnie Tyler's "Total Eclipse of the Heart" - Total Eclipse del Amor by Lissette.

https://www.youtube.com/watch?v=u3_snyvNNNk

I used it when I was studying Spanish because I grew up on rock ballads.

Ordinarily I would suggest "anchoring" foreign language generated lyrics to known melodies - but this would might run you pretty quickly into copyright issues.

You can't rely on Flock's "transparency" reports either, they're woefully inadequate. In our County, the Sheriff spoke of a PD in the County getting a Flock hit. It was news to many, including Flock's transparency site, that that PD was a user of their services.

So I'm not overly surprised by this.

The presentation is nice, but some of the conversions are questionable.

For instance: The cost section, wherein 1kWh in the US is figured as having a cost of 9.7 cents.

In reality, it's not that way at all. Unless we're fortunate enough to live in an area where we can walk over to the neighborhood generating station and carry home buckets of freshly-baked electricity to use at home, then we must also pay for delivery.

On average, in 2025, electricity was 17.3 cents per kiloWatt-hour -- delivered -- for residential customers in the US.

It's probably coming soon for you, 30 states have bills announced or introduced legalizing plug-in solar and one (Utah) has already passed. They should be fairly uncontroversial.

Also, there's no need for a transfer switch in any grid-tied system, whether plug-in or hard-wired. Grid-tied inverters shut off automatically if there's no grid frequency to sync to.

> Surely you agree that we would all want the DM of an unwell player to seek help, right? And that, if such a DM made such a suggestion, we'd think they were trying to help.

If a DM made such a suggestion, they wouldn't be playing the game anymore. That's not an "in game" action, and I wouldn't expect the DM to continue the game until he was satisfied that it was safe for the player to continue. I would expect the DM to stop the game if he thought the player was going to actually harm himself. If the DM did continue the game, and did continue to encourage the player to actually hurt himself until the player finally did, that DM might very well be locked up for it.

If an AI does something that a human would be locked up for doing, a human still needs to be locked up.

> So why are you trying to blame the AI here

I'm not blaming the AI, I'm blaming the humans at the company. It doesn't matter to me which LLM did this, or who made it. What matters to me is that actual humans at companies are held fully accountable for what their AI does. To give you another example, if a company creates an AI system to screen job applicants and that AI rejects every resume with what it thinks has a women's name on it, a human at that company needs to be held accountable for their discriminatory hiring practices. They must not be allowed to say "it's not our fault, our AI did it so we can't be blamed". AI cannot be used as a shield to avoid accountability. Ultimately a human was responsible for allowing that AI system to do that job, and they should be responsible for whatever that AI does.

I was homeless for a bit in my teens. My spouse (MI issues) left us for the nearby homeless community about 2018 and went in/out of homelessness until 2023.

My 5 kids and I were facing homelessness in 2021 when our long time rental was sold and nothing was available. Each listing had 400 new applicants per day. We managed to beat the long odds tho.

Since then we've been safe (which took a while to get used to).

the "event becomes a file write" abstraction is clean. it gives you a uniform interface regardless of where the trigger comes from - the agent doesn't need to know if a human wrote it or a daemon did.

the dashboard-as-document idea is pretty much exactly what we ended up needing. in our case the operational state (which sessions are live, which proxies are assigned, what their detection status is) was getting stale almost immediately in any static doc. a watcher that keeps specific fields fresh while leaving the rest of the doc stable solves that without turning the whole thing into a firehose.

we actually built around this problem specifically - CloakBrowser (https://github.com/CloakHQ/CloakBrowser) is focused on browser session isolation, and the state-sync piece was one of the harder parts to get right. each session has runtime state that no static spec can capture. the file-write pattern for feeding live state into agent context would have saved us some pain early on.

curious about the sectional write-back you mentioned building - does the agent target sections by header, or is it more like named anchors in the markdown?

To me the price seems to be so uncharactaristically low for Apple during a time where hardware prices are rising across the board that this almost feels like an attempt to try and capture the desktop market. During a time where Microsoft is fumbling with Windows on every front, having a competitively priced Macbook even for budget-concious people seems like a smart move that will pay off even without direct high margins.

I no specialist of the field at all, but in the context of Kyutai they explained their workflow a bit to make their speech to speech model. And basically it boils down to: if you want to make a TTS
(text to speech) model, you can generate audio track using an STT (speech to text) model, and then you have a supervised audio/text pair. You can even add as much noise to the audio as you want, to make a noise resistant STT model.

that's a fair concern to raise. any tool that helps browsers look more human can be misused.

the actual use cases we see are mostly legitimate automation - QA teams testing geo-specific flows, price monitoring, research pipelines that need to run at scale without getting rate-limited on the first request. the same problem space as curl-impersonate or playwright-extra, just at the session management layer.

could someone use it for spam? technically yes, same as they could with any headless browser setup. but spam operations generally don't need sophisticated fingerprinting - they're volume plays that work fine with basic tools. the people who need real browser isolation are usually the ones doing something that has a legitimate reason to look human.

Imagine if some other authority figure like a teacher or therapist did this and their employer would just shrug and lament that people are imperfect. And no, "but LLMs aren't authority figures, they're just toys" isn't any sort of a counterargument. They're seen as authority figures by people, and AI corpos do nothing to dissuade that belief. If you offer a service, you're responsible for it.

But if you think LLMs can't be equated with professional authorities, just imagine a company that employs lay people to answer calls or chat requests, trying to provide help and guidance, and furthermore, that those people are putatively highly trained by the company to be "aligned" with a certain set of core values. And then something like this happens and the company is just "oh well, that happens". You might even imagine the company being based in a society that's notoriously litigative.

The test harness point is spot on but there's a gap worth naming: the failure modes you write evals for aren't the ones that cause users to churn. Prod conversations have a whole category where the agent doesn't error, it just confidently goes sideways in a way nobody wrote a test for. The teams actually retaining users from AI products are reading conversations, not just dashboards.

Deepseek is in Hangzhou, so I guess they are. GDP/capita in Zhejiang is pretty high, even more so for HZ. If you ever visit, it feels like a pretty nice place (especially if you can get a villa around xihu). I also visited ZJU once, and it was pretty Macbooky, but I don't have as much experience there as Beijing's Zhongguancun.

The framing of voice as a turn-taking problem rather than transcription is the key insight here. Most voice systems treat audio as text-that-happens-to-be-spoken — run STT, process text, run TTS. But human conversation is fundamentally a signal processing problem. Turn boundaries are detected by prosodic cues (pitch drops, energy decay) long before the semantic content resolves.

The 0ms median inter-speaker delay stat is well-known in conversation analysis literature. Humans predict turn endings using syntactic and prosodic cues ~200ms before the speaker finishes. Any system targeting natural conversation latency needs to do the same — predict, not react.

What's your VAD + end-of-turn detection stack? Curious if you're doing any spectral analysis on the audio signal itself or purely relying on the LLM for turn boundary detection.

> In a sense, they're not fighting the US/Israel. They're fighting our datacenters.

LOL. Sorry, this is silly. Do you really think that Iran hates data centers?

The best scenario for Trump is to make this a limited war that nobody even notices outside of Iran's borders. He wants to announce to Americans "see? We did what we wanted and it was over in a few days, you barely noticed it".

While the nightmare scenario is to end up bogged down in a long drawn war with global repercussions, inflation, market crashes or even boots on the ground for months and years.

Iran can't win a military confrontation with the US, but it can make it so expensive that the US will decide to back off. These are strategic attacks, their form of "second strike". Raising the price of an attack on them, exactly as a nuclear armed country would retaliate on cities and not on military bases.

The "central server is usually right" framing holds until you hit cases where ordering matters and latency is non-negotiable. We ran into this building conversation stores for AI agents where concurrent turns need to converge without a strict lock - last-write-wins breaks fast when two agents update shared state mid-session. Hybrid approach: OT for the ordered log, CRDT-style semantics for ephemeral state. Not elegant but it works.

Most of that doesn’t apply, the RAM is part of the SOC so the same as the phone, the SSD controller is part of the SOC so the same as the phone. This isn’t an old fashioned Intel system, this is a modern Apple Silicon system where everything is unified. The CPU, GPU, I/O and SSD controller are all in one SOC.

> I have no fear of calling the US President a pedo or saying Fuck the Police on my Twitter.

Does that matter? In China people don't judge the state of their civilization by how easily you can insult the police but whether you need to be afraid to meet them on the street. "I can insult my pedophile president" (who doesn't care if you do) isn't exactly a flex.

It does tell us something though that the evaluation of American life now consists of parasocial interactions with the president on social media. I'm starting to belief Bruno Maçães, ex Portuguese secretary of state, was prescient with his diagnosis that American material society has rotted to the point where life is now entirely defined by virtual interactions. That's the difference between China and the US today.

The president's a pedophile, a criminal, undeterred by democracy, economy or social disorder but you can freely yell into the void. Have you considered that in the US one can freely say all these things precisely because that's irrelevant?
Show HN: LearnCodeGuide- AI tool that analyzes you code and gives a health score
by AndreiDia | 2026-03-04 22:16:41+00:00
Hi HN,

I just launched the early version of LearnCodeGuide.

It's an AI tool that analyzes your code and gives it a health score with suggestions for improvement.

You paste your code, choose the analysis mode (debug, security, refactor, tests, explain or all-in-one), and the platform analyzes things like:

• logic issues
• performance problems
• security risks
• maintainability problems

It then returns a score and detailed findings with suggested fixes.

The project is still evolving and I'm actively improving it based on feedback.

I would really appreciate thoughts from other developers.

One thing missing but important to understand is the energy embodied in buying 'stuff'. At a very rough approximation, the cost of stuff, especially consumer goods manufactured cheaply, is quite a high percentage energy.

When you look at people's energy usage, quite a lot of it ends up being the embodied energy in the stuff they buy. For quite a lot of people, it's probably the largest category of energy consumption. I once had a very rough go at calculating this here: https://www.robinlinacre.com/energy_usage/

> Do gun manufacturers get sued for mass shootings at US schools?

Odd examples since we know that countries that don't hand out guns like they're candy have virtually no school shootings.

I wouldn't put it solely on gun manufacturers, but the manufacturers, sellers, lobbyists, regulators and politicians are definitely collectively responsible for gun deaths. If they're not currently being sued, they should be.
