When I look at how far tech has come in my own life, I'm mid 50's, I don't think the singularity is out of the question in my kids life, or even my own if I'm lucky. When I born there was no such thing as a PC or the internet.

As far as I'm aware, the only missing step is for the llms to be able to roll the results of a test back into its training set. It can then start proposing hypotheses and testing them. Then it can do logic.

I don't understand the skepticism. LLMs are already a lot smarter than me, all they need is the ability to learn.

** Wikipedia definition of singularity. "an upgradable intelligent agent could eventually enter a positive feedback loop of successive self-improvement cycles; more intelligent generations would appear more and more rapidly, causing a rapid increase ("explosion") in intelligence that culminates in a powerful superintelligence, far surpassing all human intelligence.[4]"

It is worth checking out PHP for when you are building backend. I did not use Laravel because I had some issues with it (lack of flexibility in some cases) so I ended up creating my stuff from scratch. I am glad I did. It is well documented, modular, maintainable, not bloated, etc. I can give you the resources I have heavily used.

From the link, what appears to be the crux of the issue:

> Figure 1 shows plots of [solar] energy irradiance as functions of both wavelength and frequency. The red line is the solar irradiance at the top of the atmosphere. The green curve in the left panel is the corresponding blackbody irradiance for a temperature of 5782 K, reduced by the distance of the Earth from the Sun

> The peak of the blackbody irradiance spectrum is at 501 nm for a temperature of 5782 K. This corresponds to a frequency of ν = c/λ = 5.98 ⋅ 10¹⁴ Hz.

> The right panel of the plot shows the same solar data plotted as a function of frequency, along with the corresponding blackbody spectrum

> Note that when plotted as a function of frequency, the solar and blackbody spectra have their maxima near 3.40 ⋅ 10¹⁴ Hz, which is not the frequency corresponding to the maximum when plotted as a function of wavelength in the left panel. Indeed, 3.40 ⋅ 10¹⁴ Hz corresponds to a wavelength of λ = c/ν = 880 nm.

> In other words, when plotted as a function of wavelength, the solar irradiance is a maximum near 500 nm, in the visible, whereas the maximum is at 880 nm, in the near infrared, when the spectrum is plotted as a function of frequency.

[emphasis original]

> This occurs because the relationship between wavelength and frequency is not linear, so that a unit wavelength interval corresponds to a diﬀerent size of frequency interval for each wavelength: ∣dν∣ = ∣c / λ² dλ∣.

However, it continues:

> Figure 2 shows the solar photon irradiance [number of photons per second, as opposed to number of joules delivered per second] and the corresponding blackbody spectra

> Now the maximum is at 635 nm when plotted as a function of wavelength and at 1563 nm, in the short-wave infrared, when plotted as a function of frequency. The maxima are at still different locations if the spectra are plotted as a function of wavenumber.

This time the emphasis is mine. This contradicts the explanation given above, that the curve peaks in different places along different scales because those scales are nonlinearly related. The relationship between wavenumber and frequency is linear. Why does that lead to a different plotted peak?

Are we measuring wavenumber somewhere within the atmosphere (where?), rather than in a vacuum? That would mean that different frequencies of light had different velocities, complicating the relationship between frequency and wavenumber. But it would also be a strangely artifactual way to represent solar irradiance. What's so special about wherever it is that we standardized wavenumber measurements?

One time, when we were discussing a potential internal change that threatened to break ill-behaved software, Steve Summit told a story like this:

"Once upon a time, pointers on the Macintosh had 24 bits. The upper 8 bits were reserved for flags. Apple warned developers not to look directly at the flags in the upper 8 bits, but to use the macros that were supplied as part of the API -- but third-party developers looked directly at the upper 8 bits anyway. When System 7 came out with full 32-bit pointers, a lot of old applications broke because of this!"

Of course, what he didn't mention at the time was that System 7 provided a toggle that allowed these programs to run with old-school 24-bit pointers -- the equivalent concession is something I don't think OpenBSD is willing to make.

Nevertheless, vendors can and have broken full backward compatibility in cases where the developers "should've known better". Hyrum's Law just states that there will be a few that don't get the message and will watch their software break when these changes are made...

>You won't find any company offering Jeans that last more than a year or so

I literally just linked to a pair of jeans that you will try and fail to kill over a lifetime of use for most people.

If you still need bigger, Naked and Famous make 32 oz and 40oz, but the heavy denim crowd has bought them all and it's hard to find them right now.

Trying to teach HN how to buy high quality clothes is like talking to a brick wall.

This is 25 oz from the same brand: https://bravestarselvage.com/collections/heavyweight-selvage...

Quoting their description: "Selvage denim of this weight and caliber are rare, expensive and very difficult to manufacture here in USA due to the sheer weight, thickness of the yarn and time factor involved in slowing down the production line.

Each sewing operation has to be considered and necessary adjustments need to be made to accommodate the weight. Our sewing operators are required to wear safety goggles during the sewing process due the frequent exploding needles which can be quite dangerous. Needless to say it's extremely time consuming due to the half speed at which the operations can be accomplished which makes it a very labor intensive production process. "

I'd like to see you kill that in a year, or 10.

I found some 22 oz from some Indonesian selvedge company for 124 USD: https://wingmandenim.com/product/zero-zeke-22oz/

Japanese materials.

You just don't know how to buy jeans.

I use the agent panel in my editor of choice (Zed).

For each task I always start with a new (empty) context and manually tag relevant files to include (this is trivial since I know the codebase well).

First I use Claude 4 Sonnet in thinking mode (I could also use Gemini 2.5 Pro or Opus as per antirez' recommendations) to come up with a detailed plan on how to implement something (research/planning phase). I provide feedback and we iterate on the plan.

Then, in the same conversation I switch to Sonnet 4 non-thinking and tell it to implement what we just devised.

I manually review the changes and trst them. If something needs fixing or (more often) if I notice I missed some edge case/caveat, I tell it to do that (still same convo).

Commit, clear convo, next task.

For research that isn't directly tied to the code, I use ChatGPT or Claude (web apps) to brainstorm ideas, and sometimes copy/pasre these into the editor agent as starting point.

That's not how regulatory compliance works.

You invited people to a site you made publicly available that is not doing the utmost basic of things and you show zero consideration for your users publicly when confronted over your lack of compliance in your legal obligations to your users (e.g., me). You even continue to have it public with these problems mentioned above.

Someone should make an example of people like you as to why rushing to upload vibe coded slop is an idiotic idea when you have zero grasp of the law and didn't even consider seeking legal counsel to sanity-check what you were doing.

The problem isn't going away. You even scored an own-goal by having Cloudflare's "always online" feature enabled to add your non-compliant site to the Wayback Machine. Nice going, genius. Bad moves at every step of the way, and it is abundantly clear you are out of your depth.

You're self-congratulating in public over storing data in .txt files whilst not complying with the utmost basic of laws when handling PII and doing nothing about it.

Good luck. Your reputation is shot.

> "100% lies about immigrants and vaccines"

There was frustration around the globe about pandemic policies. Specifically lockdowns, mask mandates, check-ins, and "no jab no job" ultimatums, which have since been identified in many places as excessive abuse of power that went beyond public health all the way into the social coercion manipulation zone.

On immigration, is it not worth listening to the concerns of locals on rising immigration numbers? On associated social unrest? Or do we label them "100% liars" and censor their words with mandated face-scanning and digital check-ins.

I’ve got a background in electronics.

Tear downs on YouTube are invaluable.

Unless I’m explicitly buying something to take it apart I avoid anything mains powered.

You can replace the plugs and cables with compliant ones. And you can fix the lack of proper earthing. But who knows what other problems there are.

For household items, I do tend to stick to known brands and would probably avoid places like Amazon.

In the U.K. we have various high street shops such as John Lewis that do have reputations to maintain.

I would also avoid anything that has large lithium batteries.

Some basic heuristics can go a long way. Does a £2 USB-C charger that claims to do 200W make sense? Probably not…

I don't work at Google anymore and don't have any special insight into the internal adoption of io_uring, but I think it stands to reason that Google would benefit tremendously from rolling out a higher-performing way to do IO across their fleet. I mean, having myself done some lowish-level performance/optimization work and knowing that the impact of these kinds of changes is measurable and the scale is almost fleetwide, I wouldn't be surprised if the benefits - after major internal libraries/tools are also updated to use io_uring - are O(Really Big Money)

Having talked to members of their prodkernel team about other subjects, I also think they are competent enough to know the difference between "not ready" and "acceptably flawed". And believe me, the incentives are such that O(Really Big Money) optimization projects get staffed unless there is something making them infeasible.

Not everybody has the same threat model and security stance as Google and that's ok. But personally I would take their internal adoption of io_uring very seriously as a measure of whether it's safe for me to adopt it, especially if I'm running untrusted or third party software (including certain kinds of libraries).

Another consequence is that exponentiation a^b can be considered the same thing as b -> a.

In the case where a and b are not strictly boolean (supposing they are instead probabilities for example) you could even generalize it somewhat in terms of "pure" mathematical operations.

double implies(double a, double b) { double dif = a - b; double abx = sqrt(dif * dif); return 1 + pow(0, abx - dif) - pow(1, abx + dif); }

Kind of silly, I know, but it does work.

>> So let’s ask ourselves: would AI have told us this?

My first thought: if it did, would you believe it?

> Yes and it did

And before today and this thread, if I asked something like it honestly, without already knowing the answer, and an LLM answered like this...

... I'd figure it's just making shit up.

Before AI will be able to "pretty much solve all our outstanding scientific problems Real Soon Now", it needs to be improved some more, but there's a second, underappreciated obstacle: we will need to learn to gradually start taking it more seriously. In particular, novel hypotheses and conclusions drawn from synthesizing existing research will, by their very nature, look like hallucinations to almost everyone, including domain experts.

The breakdown used by OTel isn’t all that bad: https://opentelemetry.io/docs/concepts/signals/

In essence:

Logs mark some event in the system.

Metrics model some measurable, quantifiable state.

In high volume systems both can then be observed through various sampling techniques. A key item is that sampling is good to handle separately to application logic creating those signals as it may change over time or be dynamic.

Just force of habit. Being around such forceful magnets is not a daily occurrence so you don't really think about this sort of thing (for both the wife and husband). I can totally see how something like this happens.

I once bought a can of coke and put it in my backpack, then I forgot about it. At the airport a few hours later I went through security and didn't think about it at all. No idea why my bag was selected for a manual check. Until he pulled out the soda can. Big (but harmless) do'h moment. People's brains and memories are just wonky like that sometimes; most people have a few "I'm an idiot" anecdotes like that. Even with training by the way: which is why checklists exists for safety critical stuff. "They have been warned about MRI dangers" is pretty meaningless.

The failure is 100% on the facility for not properly controlling access to the MRI room, and people can just walk in apparently(?) And no, a sign or some briefing doesn't cut it.

This is also a risk for absent-minded staff by the way: I don't think I'm the only person who has walked in the wrong room by accident. Or just a small confusion about whether the MRI is operational. Things like that.

The Netherlands is an accountant's wet dream. Everyone with assets here has a personal double-layered corporate structure where the assets are held by the one company, but they're nominally employed by the second one. Even cars for every-day use can be business-owned and then leased back to yourself. And the corporate tax rate is nowhere near the personal wealth tax, people here don't even bother with registering their assets in foreign holdings.

That design you describe is what is pictured at the top of the article.

Problem is that then the keys are not equally spaced chromatically (e.g. larger spacing between B and C than between C and C#).

You could probably get used to play like that, but it would be ineficient in terms of space for both the fingers and the mechanics of the piano (hammers, strings).

So what you do, in reality, is move some of the black keys down a bit (C#, F#) and some up (Eb, Bb) so that the spacing between the center of the keys is regular.

I don't think that's what's described in the article though?

Technically and officially, JOVE is only an "Ersatz Emacs" because it lacks an extension language, and is merely a "nonextensible imitation" of Emacs.

https://www.emacswiki.org/emacs/ErsatzEmacs

ErsatzEmacs

A ‘nonextensible imitation’ of a supposed implementation of an Emacs; by authoritative definition in RichardStallman’s 1981 publication, ‘EMACS: the extensible, customizable self-documenting display editor’, such a product is a contradiction in terms, a literal absurdity.

“Many other editors imitate the EMACS command set and display updating philosophy without providing extensibility. Despite that deficiency, and despite the greatly reduced set of features that results from it, these can be useful editors, though not as useful as an extensible one. For a computer with a small address space or lacking virtual memory, this is probably the best that can be done.

“The proliferation of such superficial facsimiles of EMACS has an unfortunate confusing effect: their users, knowing that they are using an imitation of EMACS, and never having seen EMACS itself, are led to believe that they are enjoying all the advantages of EMACS. Since any real-time display editor is a tremendous improvement over what they probably had before, they believe this readily. To prevent such confusion, we urge everyone to refer to a nonextensible imitation of EMACS as an ‘Ersatz EMACS’.“

– Richard M. Stallman. EmacsTheExtensibleCustomizableSelfDocumentingDisplayEditor. MIT AI Memo 519a, 26 March 1981.

https://www.gnu.org/software/emacs/emacs-paper.html

(I don't have a dog in this fight, but I do have a cat named Emacs, and have known RMS and used and programmed and developed display drivers and user interfaces for Emacs for a long long time.)

Hi HN,

I built iProduction to help small factories move away from Excel, paper forms, and WhatsApp. It’s a lightweight manufacturing management system focused on production tracking, inventory, and order management — all with a one-time payment, no subscriptions.

Features:

Track production orders and stock

Role-based access (admin/manager/operator)

Easy for non-technical users

Many small manufacturers can't afford monthly SaaS tools — this aims to be a practical alternative.

Would love your thoughts or feedback!

> As a result, there's hardly any overtaking unless an egregious mistake is made. The lame solution they have to this is to allow cars one second behind to mechanically reduce their drag in selected spots of the track (DPS).

We've had some of the highest overtakes per season in recent years. Tracks like Monaco have always made for low overtakes, but DRS has been a great addition. Overtaking in F1 is difficult because of the dirty air from the car ahead, which has only gotten worse with improved aero, not because the cars are wider. Yes, DRS only reduces drag, but it's a necessary counterbalance to the turbulence. I believe it results in a true slipstream effect, which is exactly what you would have without the dirty air.

This is what we did to improve our docs.

We built a tool that sets up screen recording links that, once the screen recording is complete, transcribes, AI processes and writes a page into our wiki with the video embedded into it.

The tool is pre-configured with standard meeting or documentation configurations so that the tool knows how to process each meeting or screen recording and transcript.

For instance, we'll have a documentation type called 'Infra/Terraform Notes' which once the screen recording is stopped generates a video, transcription, AI summary, keywords and writes it into the correct part of the wiki.

Further, we've introduced workflows so that you can chain multiple instances of this so that the AI can get smarter. For example; we've got a workflow for Requirements Docs where;

* we record the discussion with the client where they explain what they want

* that is transcribed and the tool knows to generate a Requirements Doc

* the developer adds a recording where he/she records screen recording explaining their approach to the problem

* that generates the developer design doc (using all the transcripts/ai output so far)

* the developer finishes the feature and records a screen recording explaining the outcome

* that generates a test plan for the QA person (using all the transcripts/ai output so far)

* QA person records a video showing all the testing that was done

* that generates release notes (using all the transcripts/ai output so far)

All this is compiled into automatically into a 'chapter' in our Features book in our wiki. The video and transcripts are added as attachments to the chapters.

It's nice to be able to go back through the whole history of a feature.
