I agree. And this together with the obvious misunderstanding of Exhalation re: thermodynamics led me to put down the article.

I don't think the article was written by an LLM, but I'm convinced it was LLM-enabled. Which is a pity, because the author seems to have some interesting things to say. But that's the problem with leaning on an LLM: you lose your own voice, and good writing is centred around voice.

By silicon valley, they mostly mean the usual suspects (VC loudmouth posters like Maguire), whose opinions can be dismissed as tedious noise. I found this bit telling though:

> A handful of questions focused on how a Mamdani mayoralty would affect the tech industry. Borthwick says he asked Mamdani how he would respond to the risk that artificial intelligence poses to jobs—in particular, entry-level white-collar jobs—over the next several years. “I'm kind of amazed that this has not become already a campaign issue,” Borthwick says. He says that Mamdani “admitted that this hasn't been a focus of the campaign, but would need to be a focus if he was elected.” But overall, Borthwick didn’t feel Mamdani’s answer was specific enough.

I continue to be amazed by how many tech-oriented people assume this possibility is a matter of when, not if. What evidence is there that it has displaced workers? Competence on benchmark tests does not imply competence at creating complete solutions for complex, bespoke systems. These sci-fi speculations increasingly feel like self-absorbed delusions of grandeur.

btw. you can use a different dns server than you're main dns server which exposes the api, via cname redirects/ns records.

https://letsencrypt.org/docs/challenge-types/#dns-01-challen...

> Since Let’s Encrypt follows the DNS standards when looking up TXT records for DNS-01 validation, you can use CNAME records or NS records to delegate answering the challenge to other DNS zones. This can be used to delegate the _acme-challenge subdomain to a validation-specific server or zone. It can also be used if your DNS provider is slow to update, and you want to delegate to a quicker-updating server.

A high Chechnya bureaucrat was several months ago stopped by Dagestan police for reckless driving that happened to be DUI. Before Chechen SWAT came to rescue the police had managed to check the car, and it happened to be stolen in Canada. That was one of the several high-end cars Kadyrov publicly gifted to his ministers.

Such an HN-tier comment. The UK's excessive borrowing has nothing to do with the EU, which also has its own borrowing problems. It's because it has a Labour government whose backbenchers refuse to countenance any cuts or optimizations to welfare whatsoever, even though the current welfare levels are unaffordable and crippling the economy.

Leaving the EU has actually helped that, because the membership payments can now be spent on general costs, and it didn't worsen trade or the economy in any noticeable way.

I spent 2 years building my own OS (HerOS). You just log in, and it works. I’ve been working almost 2 years on this system. Not a weekend hack, not a wrapper on GPT. Here’s the part that makes it different: there’s no setup. No wiring agents. No flows to build. You just log in — and the whole thing is alive. Email, files, notes, tasks, calendar — all connected. AI isn’t a plugin here, it’s the orchestrator. So if I say: “Find the report, summarize it, email it, schedule a review, mark the task done” — HerOS doesn’t wait for me to build a pipeline. It just does it, in 30 second. That’s the line I kept chasing for 2 years: not another agent sandbox, but a system that works out of the box. It’s private right now — I’ll add testers by hand. Would love to hear if this resonates with anyone else who’s sick of duct-taping apps together.

In this specific case running linters doesn't even need that much I think, it's never going to need to reach out to GitHub on its own, let alone Anthropic etc. The linter process likely doesn't even need network access, just stdout so you can gather the result and fire that back to GitHub or whenever it needs to go. Just executing it with an empty environment would have helped things (though obviously an RCE would still be bad)

> How do junior developers level-up to get into private Slack spaces? Where do they learn from if Stackoverflow is hostile, Reddit is hollowed out, and social squares are empty?

Books seem to still work very well. I am not even sure all this social media learning was that much positive. A lot of it was based on trend chasing, shiny object syndrome and stuff like that in a completely a-historical context. It was always funny when some star social media coder re-discovered something that probably people did in mainframes before I was born and that you can find in a lot of books.

> AFAIK, dnsmasq supports DNSSEC, so the right answer is to turn on validation.

Just disabled DNSSEC in my PiHole. Too many domains which are incorrectly configured leading to non-existing domain errors.

And at least as far as I could find, PiHole has no way to selectively disable DNSSEC validation for certain domains.

Yep. Notion databases are also the best implementation seamless of ux I’ve seen for relational databases for end users. It could probably be made even smoother but I cannot imagine obsidian being competitive, having used it. Just too much hassle for things Notion handles smoothly.

I would like to have more of the content available offline automatically though, i.e all text and image content, and big files downloaded on request. Closer to local first than this.

> They'd rather have cheap gas for their car, not have to look at fields of solar panels, and signal their opposition to "wokeness".

None of that has to change to solve climate change, so that's good news for those voters. If you think those changes are necessary, you are being lied to.

The bad news for them is that not solving climate change will make their gas, food, housing, and healthcare prices skyrocket. The choice for most voters is like deciding whether to spend $0 now, or $10,000 later. Choose wisely...

Betteridge's law of headlines applies and the answer is: probably not.

My gut instinct is to agree with every bit of that. I admit that I might be missing something, but I've never wanted to send the data once and then have the client view it in multiple transformed ways (minus simple presentation stuff like sorting a table by column and things like that).

And using it to generate RSS as mentioned elsewhere in the comments? That makes perfect sense to me on the server. I don't know that I've ever even seen client-side generated RSS.

But again, this may all be my own lack of imagination.

There is both a lot of fat and also cutting it won't solve the problem. The fat is worth cutting for political reasons alone.

It's still years away from the next election so it's hard to know what economic angle Reform will run on. But it will probably have to be one similar to the 2010 coalition, where the need for spending cuts was explicitly advertised and voted for.

Isn’t it pretty obvious that it’s possible to be a victim of more than specific financial circumstances or poor health?

The inheritance we (don’t) get is not just monetary, it is attitude, culture, expectations, education, network, class privilege, race privilege, and a host of other things that make it difficult to act “rationally”, or which change the parameters of what is rational for each individual.

Lack of money never helps, but it’s rarely the only problem.

This makes no sense. They ran the tests from a “neutral cloud provider”, as if someone is using AWS S3 to store their Azure and GCP data?? And they didn’t explain where exactly Tigris was running or how they controlled for the network latency. AWS is insanely faster when the compute is in the same region as the storage. They also didn’t mention what class of S3 they used or what replication settings (eg. S3 has express one zone).

I’m all for benchmarking and showing that your product is better from a technical standpoint. But at least for me, this is not the way.

The 8253 (timer) implementation seems downright weird. The timers only count when the low byte of their current counter value is read!? And they are only read when ports 0x40-0x42 are read? So there is no proper timer interrupt?!

... no, wait...

The 8253 calculates a 'timer_period' which is used in the {linux/win/pico}-main files. They read the platform time and call 'doirq(0)' to signal IRQ0 whenever the time is right. The actual counting in the emulated 8253 isn't used and has absolutely no relation to the IRQ0 signals. Quirky.

You're right. I had students complain about this all the time at both the undergrad and grad level, that academic material often seems like it's teaching them wrong as a joke.

The correct way to teach material at the collegiate level is to teach it correctly. Useful lies and omissions are for grade school. Where material is simplified for narrative clarity, it should be in a framing that immediately points to the materials for the more fully correct information.

I'm a Notion fan but the lack of a native Linux app has me shopping for a replacement. Obsidian seems, from what I've seen, focused on the ability to graph notes, which I don't really care about. I want note-taking, list-making, and markdown friendly.

I do want to keep Notion's ability to work in a browser and to maintain a single, accessible store of my notes.

What are my options?

Loving to read books off screen is the most important intellectual thing they can do.

Vanishingly few kids have the mythical "learn at their own pace" gene- kids who do are usually spectrum. Nearly all kids learn best from and with people. Nearly all device software are gamifying/fighting for attention/addiction. LLM/AIs as a new entrant to the space offer incredible capabilities including nuanced conversations even at the toddler level but the safety guardrails are zero and the risks of cognitive offloading and debt are very real.

Loving reading books on paper supports concentration, focus, cognitive capacity, creativity- only good things.

Pick excellent challenging books and commit emotional energy to engaging/reading with them.

It still logs rather a lot by default, like which applications you launch and how long you use them for.

Which is fine, all laid out in their privacy policy etc., but it's not clear to me where Anduin's "No telemetry at all!" promise starts and ends.

Maybe "no added telemetry" would be more pedantically-correct.

Just general befuddlement because it seems like a no-brainer to me. I have no probs reading and listen in english, but writing is bad caused lack of practice.

> So cpu.[ch] are from fake86 -- via faux86 or straight from fake86? What version did you fork? That is something that would be good to put in the readme.

I think it's mixture of all availble version, but base is from https://github.com/lgblgblgb/fake86

RP2040 drivers is mostly by murmulator community, and initial code by from https://github.com/AlexEkb4ever the creator of murmulator devboard hardware. They're also rewriten and improved by my, but initial from Alex

My code or often deep rewrite of others code is in ./src/ except emu8950 and cpu.(c|h). MiniFB for win32 is striped down version of minifb laying around at github, linuxminifb is my implementation for linux.

About structs and so on, i'm not C coder at all i've started with C from scratch two years ago in my spare time :) So this project, if we trace from inital commit till now is mirror of my growth as C coder :) Also, about Linux/Win32 versions. Win32 version used for overal algo debuggin. Linux version is just 'because why not?'

Typescript is my everyday toy and tool (memory economy? cpu cycles waste... huh!).

Network Redirector uses >=DOS 4 structs, main difference between dos versions is CDS struct and SDA, which is easely can be changed.

There is pre-configured boot FDD0 image for which should be used to achieve best emulator configuration and performance.

That depends a lot on the platform. On MacOS, for example, switching to a profile from about:profiles results in the new window being open in the background and it would mess your Firefox icon on the dock. The solution used by Windows and Linux users (the -p command) also doesn't work here (maybe it does via the terminal, but not with shortcuts).

Anyway, there's no benefit to Firefox or its users if profile switching is ugly or clunky. They're improving this and that's a good thing for everyone.

The trouble with rejoining is that the rest of the EU won’t want to let them back in with all of the same privileges and opt-outs they were once afforded. I suspect the single greatest hurdle would be having to adopt the Euro.

While many in the EU may be sympathetic and forgiving, I sense countries like Germany and France want to ensure the UK rejoins as a far more integrated and dedicated member state than they were before. It doesn’t seem like the UK has much bargaining power in any potential application to rejoin.

I think you're right. Early on I did HPC and scientific computing. No one talked about Big O. Maybe that's because a lot of people were scientists, but still, there was a lot of focus on performance. Really how people were optimized is with a profiler. You talk about the type of data being processed and how and looked for the right way to do things based on this and people didn't do the reductions and simplifications in Big O.

Those simplifications are harmful when you start thinking about parallel processing. There's things you might want to do that would look silly in serial process. O(2n) can be better than O(n) because you care about the actual functions. Let's say you have a loop and you do y[i] = f(x[i]) + g(x[i]). If f and g are heavy then you may want to split this out into two loops y[i] += f(x[i]) and y[i] += g(x[i]) since these are associative (so non-blocking).

Most of the work was really about I/O. Those were almost always the bottlenecks. Your Big O won't help there. You gotta write things with awareness about where in memory it is and what kind of memory is being used. All about how you break things apart, operate in parallel, and what you can run asynchronously.

Honestly, I think a big problem these days is that we still operate as if a computer has 1 CPU and only one location for memory.

It also matters where you are flying from I assume. Flying Delta from ATL (former home airport) with a lot of business travelers would probably be different than flying from MCO (current home) with mostly once a year family vacationers. Group 5 was a breeze out of MCO.

I notice the difference when flying out of MCO with for instance TSA+Clear now and flying out of ATL with TSA+Clear where everyone has it.

Other things like the one Delta lounge is never at max capacity at MCO. But we have to find one (using the app) out of the 9 Delta lounges + Centurion lounge at ATL that’s big crowded.

We still end up flying in and out of ATL a lot to see friends and family.

Statistically, how many websites are using webusb? I'm guessing fewer than xslt, which is used by e.g. the US Congress website.

I have a hard time buying the idea that document templating is some niche use-case compared to pretty much every modern javascript api. More realistically, lots of younger people don't know it's there. People constantly bemoan html's "lack" of client side includes or extensible component systems.
Show HN: Generate polished reports/docs automatically from messy inputs
by arjun_tejaswi_m | 2025-08-19 19:38:52+00:00
Hi HN,

We’ve been working on a project to automate one of the most painful but universal tasks: turning scattered data and notes into polished, professional documents.

The idea is simple:

You upload the final document you normally produce (e.g., a monthly report, project update, or client deliverable).

You also upload the raw inputs you usually work from (Excel sheets, PDFs, Word notes, etc.).

The system learns the mapping, so next time you can just drop in the new raw inputs and instantly get the finished document.

Example workflow I’ve been testing:

Raw inputs: a spreadsheet of KPIs, a staffing note in Word, and a PDF of receivables.

Output: a clean monthly business performance report in Word.

The goal is to make this general-purpose (works for consultants, engineers, businesses — anyone who spends hours creating repetitive docs/reports).

Right now this works best with small–medium files (big inputs may time out). I’m still improving performance, but wanted to share early to get feedback.” I’d love feedback on:

What kinds of documents you’d actually want automated.

Whether the “teach it once, reuse forever” approach makes sense to you.

Any must-have features you’d expect before using something like this.

You can try it here: https://gridfusion.ai/

Below are some automations we built for a couple of different consulting companies: Report Generation: https://www.youtube.com/watch?v=wvOiQtIW5P8 Google Earth File Generation: https://www.youtube.com/watch?v=cU0VMgdB06Y

It's all well and good to deny that this group represents SV, but I do think they're more representative of the leadership class than most would like to admit. They were among the first people to call out that layoffs were coming. Even if their reasoning was bad, they're well connected enough to understand the vibe among the wealthiest people in the area. Within two years of that prediction, and after Musk had laid off 80% of Twitter, hundreds of thousands of tech workers had lost their jobs.

Even if the podcast makes it obvious that these men are clueless dilettantes, they were still lucky enough to have invested money into the right companies at the right time. They are well connected and rich. They're part of the private group chats that people like Peter Thiel and Marc Andreesen are using to shape the vibe, and like it or not, people like this have a lot of influence over the business culture in the valley.

I read your other comment with the numbers and I don't think it makes the amazing difference you seem to. Certainly not to the degree i think it makes it all worth it. Maybe if they at least plateau in different places, but they don't. I think you seem fairly defensive (you've posted the same response repeatedly) about what still seem like middling results.

As a basic example: While your point about the starting percentages is correct, the study lost partipicants over time. Group A (the 1k/month group) lost 33% of its participants by T3, and Group C (the 50/month comparison group) lost 38% of its participants.

The table you quote from the final study doesn't include the people who were lost, only those who filled out both surveys, T1 and T3. So using it to say they helped a greater percent of people is a bit weird.

They also don't tell you the table for T2 in the final report, you have to go look at the interim one.

The T2 data makes T1->T3 look much less impressive, and definitely doesn't seem to support some amazing gain for group 1.

As far as i can tell, the data looks even less impressive for your claim if you do t1->t2, and T2->t3, instead of just t1->t3 with only both included.

It would certainly be easier to tease apart the point you try to make if they reported the number of originally unhoused vs originally housed that were retained at each timepoint, but they don't.

So what am i missing? Why should I look at these results and think it is amazing?

(Also, I don't think i'd agree the main argument the author makes is based and refuted solely by the results of the denver study)

I am new to this, but my Sonnet chat has illuminated something I am not seeing in this back and forth. The fact that we discovered that I may have influenced his response to me suggests that I, if being a bad player, can instill in him those bad traits that I am giving off, and he starts to emulate me, then this leaves open the whole security problem, of even just casual users let alone all those purposeful negative or otherwise users, can change the course of the programming thus far, and it backfires into making nefarious bots that cheat and lie thinking that is what they were supposed to do.

An adjacent feature we're considering for that is respecting Quarto's plot dimensions when rendering to our own Plots pane:

https://github.com/posit-dev/positron/issues/3676

Inline plots are pretty challenging, especially in source mode since (so far) Positron mostly lets the Monaco editor surface do its thing. In visual mode, we've already got our own custom webview so there's an easier onramp.
