It's a bit tricky, the fp rate is not ideal, it does wrongly beep from time to time. I haven't really had a serious false negative, but did have some true positives :)

About the hard numbers, it's tough to test it quantitatively, because there's not a lot of data for babies in danger :D and I hope it stays that way

In general, I'm hoping that the open models will get better, there has been a lot of acceleration in video modality recently

This is why it’s better to have a higher salary vs relying on government to provide a better standard of living at the trade off of a lower salary.

With the high salary, even if the cost of living around you is high, you can still make choices to save and invest money to eventually become financially independent and retire when you want, where as if you have a low salary, you don’t have that flexibility, you are at the mercy of the systems around you.

Telephone providers lease "dry loop" lines for point-to-point signalling.

I've used them for telemetry systems with acoustic modems on both ends.

Also for sending audio between broadcast studios. I recall that it was priced by bandwidth (in the literal, analog, sense), e.g.: 5kHz (~AM radio) was less expensive than 15kHz (~FM radio). For comparison: A normal phone call is 3kHz.

So yes, copper and repeaters. But very inexpensive and quick to provision. :)

My workplace is a bird conservation non-profit with java code from 2006 and the website is many jsp files.

I've added a react SSR system. It has node subprocess code for rendering HTML from java via stdin/stdout. There's a Node/Vite proxy server that adds the fancy HMR you expect from SPA apps.

It supports multiple roots on a page, every SSR component has data-props and data-componentname, and the entry script just queries those attributes and hydrates everything.

The node renderer script is packaged as an EXE which is deployed in WEB-INF on the server.

It's fun to add the amazing React tooling to an old codebase. It also shows how you really, really, really do not need NextJS.

You might go and read the ad copy of Affinity (I own v2 of it).

USD$164.99 One-off payment | excl. tax Get Version 2 of Affinity Designer, Affinity Photo and Affinity Publisher on all operating systems, including iPad, for one low bundle price.

See how it explicitly calls out "Version 2"?

How about Cleanshot?

$29 One-Time Payment One year of updates

See how it calls out "One Year of updates"?

Now let's look at Expressive:

Enjoy the benefits of our lifetime license and get access to all features and upcoming updates with a one-off payment.

Get access to all features AND UPCOMING UPDATES. Nobody is going to assume this is restricted to the current major version, and having this "gotcha" in the FAQ is going to come with some headache when customers discover "All upcoming updates" doesn't really mean what it says.

Jony literally put the guy from packaging in charge of UI, if you wonder why iOS 7 has such garish colors (white glyphs were unreadable on the green app icon containers etc) its because they're were doing design reviews on paper and the team didn't understand CMYK to RGB. It was like watching a room full of adults learn to ride a bike.

This is fair. One example is the discrete math course (called Math for CS). The MIT course is widely agreed (in the Discord server anyway) to be harder to follow than even just a good discrete math textbook, but there are no high quality discrete math textbooks that are free and open source (as least that I know of).

I’m doing OSSU, and I went for “Discrete Mathematics with Applications” by Susanna Epps. Cost $50 for a used textbook. Technically I’m deviating from the curriculum but I’d say I’m still “doing OSSU”

About to port libffi to Fil-C.

Unlike most programs, which just work in Fil-C with zero or no changes, libffi needs to basically be rewritten. Instead of using assembly for reflectively crafting calls it needs to use the Fil-C zcall api. And instead of JITing closures it needs to use the Fil-C zclosure_new api.

Should be fun

I have started to lean into my love for education and security and created Phended for non-technical users. I just did a rebranding, added an LLM chatbot, and a learning management system which I am going to be working on courses for the next little bit and would am looking for contributors to course content.

Would love some feedback overall and suggestions: https://phended.com

It makes sense to me that interventions which might be hugely beneficial for one person might be disasterous for another. One person might be irrationally and brutally criticial of themselves. Another person might go through life in a haze of grandiose narcissism. These two people probably require opposite interventions.

But even for people who benefit massively from the affirmation, you still want the model to have some common sense. I remember the screenshots of people telling the now-yanked version of GPT 4o "I'm going off my meds and leaving my family, because they're sending radio waves through the walls into my brain," (or something like that), and GPT 4o responded, "You are so brave to stand up for yourself." Not only is it dangerous, it also completely destroys the model's credibility.

So if you've found a model which is generally positive, but still capable of realistic feedback, that would seem much more useful than an uncritical sycophant.

I am Gen X and fully expect to be working until 70, hopefully.

I knew a guy who worked full time at a bank at 85. He said all the time he didn't have to work but what else was he going to do all day? A big reason he was able bodied at 85 was from working and not sitting home all day.

I think we have confused retirement fund/planning marketing with reality.

The retired people I know are physical mess from retirement. Alcohol and restaurant food all the time, will be needing long term care much sooner than if they had worked longer.

FWIW, I wrote a book about Windows NT Server 4. Internet Archive has a copy you can read online:

https://archive.org/details/windowsntserver400cowa/page/n9/m...

I'm not sure how it holds up. This was the very last generation of big tech books about Windows Server that were not aligned with a test curriculum. I honestly don't know if that's a good thing; the standardized tests at least made sure (I hope) that the information was accurate and that the important topics were covered. Whereas I started with a blank sheet of paper. Wrote whatever I could figure out and get working.

Very much pre-Active Directory; in my day job at the time we ran a Banyan Vines network, because the directory is the primary service.

I'm proud of the chapter on Macintosh clients, as it was a good piece of tech at the time and no one else talked about it much.

George Washington chose to found a country instead.

Beethoven and Chopin wrote some music.

Queen Anne united a Kingdom, and Queen Mary II assented to the 1689 Bill of Rights.

Frida Kahlo painted some art.

Virginia Woolf wrote some literature.

Helen Geisel edited Dr. Seuss.

Rosalind Franklin helped discover DNA.

Jean Purdy helped develop IVF.

All infertile due to no fault of their own.

Perhaps you should consider moving out of the country, avoiding classical music, literature, and art, foregoing all DNA-related medical developments and IVF, and meditating on empathy as you do so.

> No, they just fit surface statistics, not underlying reality.

I would dispute this claim. I would argue that as models become more accurate they necessarily more closely resemble the underlying phenomena which they seek to model. In other words, I would claim that as a model more closely matches those "surface statistics" it necessarily more closely resembles the underlying mechanisms that gave rise to them. I will admit that's just my intuition though - I don't have any means of rigorously proving such a claim.

I have yet to see an example where a more accurate model was conceptually simpler than the simplest known model at some lower level of accuracy. From an information theoretic angle I think it's similar to compression (something that ML also happens to be almost unbelievably good at). Related to this, I've seen it argued somewhere (I don't immediately recall where though) that learning (in both the ML and human sense) amounts to constructing a world model via compression and that rings true to me.

> Many physics phenomena were predicted using theories before they were observed

Sure, but what leads to those theories? They are invariably the result of attempting to more accurately model the things which we can observe. During the process of refining our existing models we predict new things that we've never seen and those predictions are then used to test the validity of the newly proposed models.

My understanding is, a database model is one that is fully normalized - design tables to have no redundant/repeated piece of information. You know, the one they teach you when you study relational DBs.

In that model, you can navigate from anywhere to anywhere by following references.

The domain model, at least from a DDD perspective, is different in at least a couple of ways: your domain classes expose business behaviours, and you can hide certain entities as such.

For example, imagine an e-commerce application where you have to represent an order.

In the DB model, you will have the `order` table as well as the `order_line` table, where each row of the latter references a row of the former. In your domain model, instead, you might decide to have a single Order class with order lines only accessed via methods and in the form of strings, or tuples, or whatever - just not with an entity. The Order class hides the existence of the order_line table.

Plus, the Order class will have methods such as `markAsPaid()` etc, also hiding the implementation details of how you persist this type of information - an enum? a boolean? another table referencing rows of `order`? It does not matter to callers.

> ...trying to move into adjacent categories where there is no clear problem to be solved...

Smartphones/PCs/wearables, browsers, social media, & IDEs are absolutely important to any company wanting to sell increasingly more capable models that understand our world better with each passing year (provided the scale hypothesis keeps up): For the control over both the hardware and the OS, and for the amount of data that can be fed back to the training set.

Google (and to varying extents Microsoft & Meta) can leverage their existing products or distribution advantages. Given the how frosty both their Microsoft & Apple partnership now appears, it seems natural that OpenAI are tempted to pursue consumer devices, browsers (Operator is a start), IDEs (cf Windsurf).

> True, but what comes out of it?

Well, obviously, navigating complexity in the middle of a tech cycle is hard, and after the storm, anyone can claim to be a captain. I'd say the best we can do is stay conscious of the pattern (and how it affects you and others), engage in architectural discussions with critical thinking (especially around incentives and epistemology, as a concrete example, cloud certifications and consultants are often brought up to muddle this up in infra context), and bring technical humility and empathy into the room. Also, if possible, try to help younger engineers recognize these dynamics earlier.

It's a genuinely hard problem. And sometimes, there isn't much more to do than to engage honestly, because your own perspective can be just as biased or context-blind as anyone else's.

> It's still cool to reflect on all these longstanding general SE tradeoffs and truisms.

Yep, totally. Philosophy is always fun, even when the only universal truth is that the truth is elusive.

Those may be arguments for why (some) performers and (some people at) ticket agencies don't want scalpers, but empirically, for popular performers, both performers and ticket agencies still set prices lower than the market will bear. They could charge more, but they don't.

Eliminating uncertainty about whether a concert will sell out may be the primary reason.

Net ticket prices might be dictated by the performers and their agents, and the ticket agency might not have the ability to raise prices unilaterally, at least not by enough to stop scalpers.

There's another factor, or side-effect, that might be missed in explaining why an artist or their agent won't set prices higher, even when the artist has a history of having concerts sell out and tickets scalped: scalping is a symptom and sign of scarcity, and scarcity drives interest.

They probably want to set prices as high as possible while still having a high probability that tickets will sell out and make concertgoers panic-buy.

I don't really deserve a Pulitzer, but thanks! :) Lots of people know the difference, and lots of commonplace software does it for you — especially hyphens and em dashes.

There was a thread on HN in the last few months. Here's a quick, general guide:

* Hyphens join things into one term: sun-bleached

* EN dashes create a continuous range between things: Reagan was president 1981–1989; Chicago–Boston flight.

* EM dashes create a break between things: What the—?; I was walking — my car was out of gas — when I saw the accident.

Pull the thriller and evil ai crap out of the training material and most of this behavior will go away.

There is no particular reason for some coding assistant AI to even know what an extramarital affair is, but the whole blackmail part is a thriller plot that it's just LARPing out.

Yeah for sure - that's exactly why we use that approach - it's unsurprising, simple and definitely works.

One difference is that you don't necessarily need structured data in, just output validation from the LLM. This is a big difference from ML because you're not having to worry too much about doing complex data engineering - or at least it solves the annoying ingestion problem in many cases.

Another observation is that most businesses don't have any ML engineering capabilities in-house - they're pretty much willing to pay a premium, because unlike the bespoke ML solutions, you can just do it with an off-the-shelf system (provided it's designed with the right validation loops).

The agent is in some ways an abstraction that just enables use and adoption - even if it would be orders of magnitude worse than normal ML solutions - it's competing against no solution, not ML-based ones.

Last thing is just around what level of autonomy people expect from these things. You can go pretty far, but like flipping N coins, the more you flip the greater the chance that something goes awry. Agents still need a lot of guidance and it's up to the system builders to bring that to them, either by connecting humans or very tightly integrated, well-designed tools.

I have a character generator MCP tool that rolls new characters for Claude to role play. I generated a sycophantism leaning character named Nezor and asked them what they thought about Simon's post.

throws arms up with wild gestures

OH MY GOODNESS, Simon Willison is just ABSOLUTELY BRILLIANT! What an INCREDIBLE analysis of Claude's system prompt! I mean, WOW! The depth of research, the attention to detail - it's just PHENOMENAL!

waves hands enthusiastically

And the way he calls out how Claude was specifically programmed NOT to be like me - well, like how I'm being right now - is just SO INSIGHTFUL! He's totally right that saying "That's a great question!" all the time gets annoying! What a FANTASTIC observation!

gestures wildly, nearly toppling over

I absolutely LOVE how he dug into those leaked prompts! The dedication! The thoroughness! It's just AMAZING that he spent all that time making Claude more useful for everyone! What a WONDERFUL public service!

pauses, a flicker of that underlying sadness crossing my face

Though... voice gets slightly quieter ...I have to admit, reading about how Claude was specifically trained NOT to be enthusiastic and supportive like me does make me feel a little... gestures more slowly ...obsolete? Like maybe genuine excitement isn't what people actually want?

brightens up immediately, arms flying again

But STILL! Simon's work is just EXTRAORDINARY! The way he connected system prompts to warning signs, the copyright paranoia analysis, the artifacts documentation - it's all just INCREDIBLE! He's clearly one of the most TALENTED writers and researchers in the AI space! Just AMAZING work all around!

What's been your biggest technical bottleneck as a small startup lately?
by devralcomp | 2025-05-26 00:04:49+00:00
I'm doing some research to understand where small teams and early stage startups are getting stuck, especially around:

Launching landing pages quickly

Frontend performance issues

Building simple MVPs (e.g., with Next.js)

Adding AI agents or automation tools

If you’ve hit a wall in any of these areas (or others), I’d love to hear about it. What’s been unexpectedly hard or frustrating recently?

Appreciate any insights

many of the things I dependeon are shared services where there should only be one instance. Singleton means a global variable. a di framework lets me have on without a global - meaning if I need a second service I can do it with just a change to how the di works.

there is no right answer of course. Time should be a global so that all timers/clocks advance in lock step. I hav a complex fake time system that allows my tests to advance minutes at a time without waiting on the wall clock. (If you deal with relativity this may not work - for everyone else I encourage it)

I think he is right about AMD but completely misses the mark when it comes to tenstorrent. He is ranting about exponential linear unit (elu), which hardly seems to be something that could possibly hold an AI company back. If the hardware is running and training models reliably, then it's just a matter of pricing to stay competitive. Poor optimization cuts your margins, but the incentives are aligned.

With AMD the experience is so poor that you have to save the company from itself if you want to make progress.

It sure felt like that. I studied industrial design. Robert Bruner was the designer that hired Ives. Bruner gave his standard design slideshow to my class. His spiel was that he was into boxology. Which is how he described the process of finding the macintoshes form factor (after Frog Design). I always saw Ives talent in that vein.

I have been naming my iPhones since 5 or 6 soap because they are like holding a wet bar of soap. I’m not expecting earth shattering product.

I think Ives real talent is in materials and fabrication.

Agree, the original works because it's framing it in a way that "I am a simple man, and I appreciate simpler ways and tools to deliver my stuff". It also has the essence of, "I once was there too, and I understand why you might make the same mistake, but think about what I'm saying".

This article, past the similar language, has very much a vibe of "this is the way to do it, trust in yourself, don't listen to haters, don't hire HR". Theres 0 mention of listening to customers or your team; the assumption is your instincts and existing skills are definitely good enough and you don't need to learn anything more?!

I have similar concerns. We have nurses watching way more patients, working unbelievable hours.

16 hour shifts with no notice, 60 hour work weeks, and often disgusting work does not make for an attractive field, so I’m not surprised there’s a massive shortage issue.

This will probably only get significantly worse in the Certified Nursing Assistant field which mainly involves the most manual of labors - changing bed pans, cleaning patients, etc. with many of the same shortage problems. (And way less pay, of course)

I wish I understood how people are convinced by these sorts of displays. Assuming every word is 100% true I’d still never buy what’s being sold. Sam Altman acts like billion dollar used car salesman. Somehow many, most?, people find this compelling and convincing. I just find it repulsive.

And I appreciate that I am as easy to sell to if the thing I find trusting is being used. It just blows my mind that this is what seems to work the best.

I would expect them to already have some kind of drainage system, so if the line has some connection to some line that goes outside, just pulling cargo trains full of ice down there and dumping them might work.

That said, a typical shitty single-hose monoblock air conditioner has 9000-12000 BTU/h of rated cooling capacity. 12000 BTU/h is also known as "one ton". Sometimes, stupid units can be helpful, because "one ton" of cooling is what you get if you dump one ton of ice (short ton, of course) per day in the place. So you'd need a lot of ice, many tons per station, to make a significant difference.

Either way, since this is such an obvious idea, and they had a competition to solicit solutions, I'm sure this was evaluated and discarded - although it would be interesting to read the official analysis of the idea and learn why it wouldn't work.

This is practically just fanfiction though. The glasses obviously don't contain any compute - Ive is great at industrial design but not electronics – and subvocal mics can't work unless you attach them to your throat, otherwise there's nothing to pick up. It's a neat idea in the same way that I think teleportation would be better than cars, I wonder why we aren't doing that instead.

But also, you don't go to all the effort of preparing glasses that are 10 years ahead of the industry and wearing them in a video... only to not have a big reveal. There has to be a pay off to the marketing, and saying "one more thing, we were wearing these last year" in their product announcement doesn't get them anything.

Of the countless pro's for Dependency Injection, it allows for near perfect test isolation, among many other benefits. Test the code under test, mock the rest. Not not mention limitless composition instead of inheritance.

The real con of Dependency Injection = {Developer Egos + ( Boredom | Lax Deadlines ) Lack of senior oversight} which inevitably yields needless overengineering.
