> To them, it’s way too convenient to be on AWS: not only it solves their problem, but it’s also a shiny object. It’s technically complex, it makes them look smart in front of other devs, it creates dependencies and lock-in effects so they’re not easily replaceable as employees, and most importantly – being on the cloud yields them a fat paycheck at the end of the month.

I recently read a fantastic comment or article on how developers, and IT workers in general, will be the first to be automated away, and groups like lawyers and doctors the last, entirely unrelated to how good LLMs and other AI models are at the specific tasks of each. Reason being that developers fall over themselves to prove how productive they are, happy to use all these tools. Anywhere else is concerned with job protection first and foremost. Metrics like SLOC having come from devs themselves in the chase of a raise.

This paragraph reminds me of that so much. Calling out those who push the cloud for job security. In basically every other sector - where this kind of behavior is 10x more prevalent - no one calls this out, there's a sense of solidarity and mutual understanding that this kind of thing is necessary.

This isn't judging one or the other to be good or bad. But it's going to cost devs very dearly.

I don't remember where I read it, they put it much better than I can - if anyone here recognizes it please drop a link.

Because the US has laughably weak privacy laws and most Americans snicker at the EU GDPR because of "cookie banners" (which btw isn't a thing - most consent dialogs are non-compliant as they shouldn't serve to just inform you but to actually obtain voluntary, revokable and specific informed consent) instead of thinking about what it means to actually have a fundamental human right to privacy and ownership of your own data or not.

They keep the samples for the same reason US tech startups keep deleted data and track seemingly useless behavior. Because they might find a use for it someday and there's literally no law preventing them from doing it.

>About the only response to this stuff a reasonable person can muster is "he doesn't believe that now".

My response is "looks good to me. Accepted". if police aren't protecting the people they shouldn't be funded by taxpayers. All for police reform.

And yes, if we aren't jailing everyone for being homeless or smoking weed, we'd need less prisons. If prisons were about reform, we'd nedd less prisons. These all make sense.

But I guess if detractors just want to take soundbites, remove all subtlety, and blast it out to twitter's 280 character limit, then their plan worked. It's just a same these same people would try to downplay 90% of the stuff Trump said in 2024 that he is doing in 2025 to the letter.

An entire 1000 foot reel of 35 mm film only has about 15,000 frames on it, so one part in 30,000 would be good enough. When I worked in TV none of the sound equipment had ovens for their crystals.

We did have a sync generator with a crystal oven. I forget who made it. The sync generator has multiple outputs, the most important one being the color subcarrier, which is 3.579545 MHz for US NTSC (I still remember that number). It also puts out vertical and horizontal sweep signals. The stable timebase allowed us to free run for a day in case we lost the network signal for some reason. The network (NBC in our case) had a cesium clock in New York that they calibrated against WWV for time of day. We locked our clock to their signal, and all our equipment to our clock.

I lived in a world without billionaires - Eastern Europe pre-1990.

It wasn't a world without powerful people though: party nomenklatura and their friends ruled us with an iron fist. Not billionaires in numbers but in lifestyle, power and ruthlessness.

Together with actual billionaires, we also lost all the products and services their work created in process of making them billionaires, so we were all cold and hungry.

I learned then to cherish societies where one could become billionaires: it meant there was enough economic freedom so that the tiny insignificant me could carve a honest, dignified living for me and my own without begging politician mercy for handouts.

We should have more billionaires.

You mean the 1990s which brought us "broken windows" policing and the frequent use of racist stop-and-frisk? When I visited Queens 15 years ago, what worried me most was the chance of interacting with cops on a power-trip.

The 1990s when NYPD cops Sean Carroll, Richard Murphy, Edward McMellon, and Kenneth Boss shot Amadou Diallo? When NYPD cop Justin Volpe sodomized Abner Louima with a broken broom handle? When NYPD cop Francis X. Livoti choked Anthony Baez for accidentally hitting a police car with a football?

If you don't think the history of being hard on crime is contentious, you are living in a bubble and greatly disconnected from huge portions of the population.

Other places have free public transport (https://en.wikipedia.org/wiki/Free_public_transport). How has that threatened the economic viability and safety of those places?

And isn't it funny how the people who complain the most about free public transport have a large overlap with the people who didn't want congestion charges but instead wanted free access to city streets for their multi-ton private vehicles?

How could city owned grocery stores threaten the economic viability and safety of NYC? The only way that makes sense to me is if the economics of NYC depended on having a working class which is always on the edge of food insecurity. Were that the case, the economics structure of NYC must change, yes?

Since homeless shelters threaten the economic viability of hotels and rental companies, and libraries threaten the economic viability of bookstores, I suppose we should get rid of those too.

It's a plague under TUI go software too made with Bubbletea. Also, with some mesh related interfaces written in Python. Both slow and with a shitty interface not properly working under an 80x24 terminal with 16 colours.

I remember some hipster fauxretro player with just some playlist made of m3u links, written in Go. The visualization animations made it unusable under my n270 CPU based netbook. Meanwhile, the playlist URL's from the code played perfectly well under mocp with a really low CPU usage. Oh, you want bells and whistles? I think the Cava terminal visualizer can work with MPD and plug any CLI/TUI client you like.

These terminals properly handle single + double width fonts. But the same thing could work with single + half width fonts, so i,j,l,:,!,.,' and space would fit in half the width. Does anyone know of such a font? I searched but couldn't find any bi-spaced font with full/half width cells.

It would not only fit more text on a line, while (probably) also being nearly as pleasing as a proportional font, but it would also still perfectly align indents. I think it could be a great markdown font.

I'm using sqlglot to parse hundreds of old mysql back up files to find diffs of schemas. The joys of legacy code. I've found hypothesis to be super helpful for tightening up my parser. I've identified properties (invariants) and built some strategies. I can now generate many more permutations of DDL than I'd thought of before. And I have absolutely confidence in what I'm running.

I started off TDD covered the basics. Learned what I needed to learn about the files I'm dealing with, edge cases, sqlglot and then I moved onto Hypothesis for extra confidence.

I'm curious to see if it'll help with commands for APIs. I nothing else it'll help me appreciate how liberal my API is when perhaps I don't want it to be?

You don't leave iris prints everywhere you go. Even most fingerprints you leave are unusable for identification. Contrary to what CSI may have taught most Americans, even usable DNA samples aren't a given.

Biometrics aren't "publicly available" let alone "easily obtainable". They're easy to extract from you but this is why extraction and retention of this kind of data should be considered extremely invasive and sensitive. That wallet in your pocket may be "publicly available and easily obtainable" but that doesn't mean we should treat it as such - rather we should make sure it's actually illegal to do so without your consent: that's why theft is a crime.

> It's much easier to bully teenagers and small businesses into questionable settlements.

The world's biggest publishing, copyright and IP holders (like Disney, Thomson Reuters, Sony, etc) aren't teenagers or small businesses, and easily have a war chest as big as AI companies, and own about 90% of media IP on which LLMs are trained on, not to mention having lawmakers and artists unions on their side.

If they have a case under current laws, they'll take it to court.

Love the cheat sheet, forked it after reading a couple sections that were instantly useful lol

Can't promise it'll be soon but I may be able to expand on a couple of your repo's "possible future topics list" items.

I've been working on a personal project involving doing object detection on multiple camera feed inputs that all have different resolutions, frame rates, and encodings and sending a single consolidated and annotated feed to a remote streaming service.

That sent me down a really interesting rabbit hole and I've got tons of notes and links along with some Gemini chats that I'm gonna go through and see if there's anything there that might be worth including.

> Yet their demands are almost entirely about limiting restrictions imposed by Google Play.

Because most people only ever use the Google Play store. Epic can invest all the effort they want into their own store, but that won't help if the audience is elsewhere. You are basically making the "just build your own Twitter/Facebook" argument - it's about the audience, not the technology.

> Anyone here use this testing in the wild? Where's it most useful? Do you have the issue I described? Is there an easy way to overcome it?

One example would be when you have a naive implementation of some algorithm and you want to introduce a second one, optimized but with much more complex implementation. Then this naive one will act as a model for comparisons.

Another case that comes to mind is when you have rather simple properties to test (like: does it finish without a crash, within a given time?, does not cross some boundaries on the output?), and want to easily run over a sensible set of varying inputs.

The problem with using this kind of monitor for any work that others will view on their own monitors is that your perception of what looks good will be way off. For example, it's clear that a lot of the Rust UI framework developers have been working on Macs for the last few years. The font rendering on many of those look bad once you plug them into a more normal DPI monitor. If they hadn't been using Macs with Retina displays they would have noticed.

> Would you be willing to submit to invasive investigations into how you live to identify any risk factors you have

To be fair, there are insurance policies (at least in the UK) which give you discounts if you drive "safely"[0] or health insurance that rewards you for "being active"[1].

32" 4k is pretty much the worst of all worlds configuration. It is just dense enough that traditional 100% scale is not great, but not dense enough to get that super smooth hidpi effect either. I'd argue that for desktop monitors around 200 ppi is sweet spot, so 5k for 27" or 6k for 32".

This 8k is bit overkill, but I suppose makes some sense to use a standard resolution instead of some random number.

Hey HN,

I built a tool to help find intent signals in online discussions where people are already asking for recommendations or describing pain points.

The idea came from the frustration of classic lead gen: scraping lists, sending cold outreach, trying to contact people who never asked to hear from you. But some of the best leads come from real conversations — forums, discussion threads, niche communities, etc. The problem is that finding those conversations manually takes hours every day.

What Leado does:

Monitors discussions in real time

Identifies posts that signal buying intent (e.g., “looking for X tool,” “we need help with Y”)

Summarizes context and reasoning

Suggests a natural, useful reply that adds value first, not a sales pitch

What it does not do:

No scraping emails

No mass automated outreach

No spam

No growth hacks Just surfaces conversations where showing up is actually helpful.

Why I built it: I was tired of cold outreach that felt forced. I wanted something that points to where a helpful answer is genuinely useful.

Here’s the product: https://leado.co

I’d really appreciate any feedback:

Thanks for sharing! Your article illustrates well the benefits of this approach.

One drawback I see is that property-based tests inevitably need to be much more complex than example-based ones. This means that bugs are much more likely, they're more difficult to maintain, etc. You do mention that it's a lot of code, but I wonder if the complexity is worth it in the long run. I suppose that since testing these scenarios any other way would be even more tedious and error-prone, the answer is "yes". But it's something to keep in mind.

Daddy chill. I was continuing the thread.

If you have a look around on the interwebs there are longstanding criticisms of how overpowered the iPad is relative to what you're actually empowered to do with it, and by extension the question of who is it supposed to be for. Like you said, Apple doing Apple.

I'm sure a lot of them sit idle because a constant complaint people have (again all over the interwebs) with them is that they aren't good at much besides media consumption, and are rarely people's first choice for that due to convenience.

Whatever though? It hardly matters. Enjoy your iPad I guess(?)

Government runs a lot of businesses alongside private estates. Postal is the biggest example. Why is this super unusual? I don't know if it's middle of the road, but I don't think it's socialism.

Progressive ideas would be price controls on groceries to curb inflation, or seizing the means of production by making a major stake in a major food chain.

(side note: I think it's hilarious that Trump is doing this with Intel and potentially Tiktok and few have labeled it as such).

Counterpoint: The country really needs to learn how to have a grown up conversation and not allow the dumbest people in the room with the least generous interpretation of everything possible who were never going to vote for you anyways to constantly set the agenda.

Sensible voices are a rare thing in this climate and it’s incredibly easy to stand out as one if you stop playing by a set of rules that were intentionally designed to make you fail in the first place.

Honestly I think the American exceptionalism shit is a cancer on the society and I find it incredibly hard to distinguish from the "Deutschland über alles" nonsense that the Germans went through. It’s just a fundamentally flawed way of looking at the world. It’s like a story a small child might believe but it really doesn’t stand up to even the most gentle of scrutiny.

What may be information regarding a check for position of trust today, may well be information regarding a check if you should be locked up because of other reasons, tomorrow.

The issue is not the information itself, but how the information will be used. The chance of abusing information is not zero. But having rigorous rules and processes regarding that information, for instance mandatory destruction of said information, will greatly reduce the chance of abuse in the uncertain future.

So you end up paying an AI company (or subsist on not-endless free tokens) to circumvent another company's paywall? This doesn't sound like a sustainable solution.

How reliable is it? Can you just ask an AI for a doi and get a reasonably correct copy of the original article back? Is the level of hallucination induced in science acceptable?

Depending on degree of cynicism*, both takes are compatible with what was observable: https://en.wikipedia.org/wiki/World_(blockchain)

* For what it's worth, my cynicism for Worldcoin and that eye scanner thing is currently about 7/10: moderately high but could be much worse.

By comparison, I'm 9/10 in cynicism for Facebook and 10/10 in cynicism for everything Musk does except SpaceX, my SpaceX cynicism is only 5/10.

You might find schemathesis useful for API testing (which IIRC is built on Hypothesis). Certainly helped me find a stack of unhandled edge cases.

YMMV, but once I first set up Schemathesis on one of my MVPs, it took several hours to iron out the kinks. But thereafter, if built into CI, I've found it guards against regression quite effectively.
A Portfolio Ended My 4 Month Job Search and Started My Side Income
by dongyue95 | 2025-11-05 09:27:12+00:00
Job hunting as a junior AI/ML engineer is brutal. I was about to graduate and spent four straight months applying everywhere, startups, labs, even freelance gigs. Nothing. Not a single callback. At one point, I even looked into those career consulting agencies that promised guaranteed interviews, until I saw the prices. Out of desperation, I figured maybe I could at least make a small portfolio site to look more legit. So I used MGX, nothing fancy. I uploaded my resume PDF and gave it one simple prompt: "Turn this resume into a clean, functional portfolio site deployable on Vercel. Use only the exact information and links from my resume, ensure every link works and all functions run properly. Here are my project GitHub links to include. Please replace the phone number field with a 'Schedule a Call' button linking to my calendar, and keep the section headers clickable for navigation." Two minutes later, I had a fully built page with all my resume sections intact, just a free personal blog template that I tweaked to showcase my work. I dropped the link on LinkedIn and X, and within three weeks, things completely changed. I started getting messages from recruiters. Real ones. Then came interview requests, more than ten in less than a month, and a couple of part time remote offers for small AI automation projects. I'm now working full time, finally, and still earn $150-$300 a week from one of those side projects. I know it sounds a bit dramatic, but that tiny website literally flipped my job search around. For anyone stuck in the same boat, seriously, just build something visible. Even a simple AI generated portfolio makes you stand out way more than another PDF resume floating in someone's inbox. Would love to hear if anyone else had a similar AI tool changed my job hunt moment.

I don't have a hot take to add here, but I just wanted to say that this article is terrific. Great insights and detail, great clarity for a general audience without dumbing down the technical content in the slightest. Of course it raises more questions than it answers; that's the point of this kind of thing. It's going to be a really useful reference point on the 2025 state of the art in years to come.

This is some of the best writing on AI since Ted Chiang's "ChatGPT Is a Blurry JPEG of the Web". And that was in the New Yorker too! Might need to get myself a subscription...

I created a side project ~3 years ago based on a similar idea. It was before LLMs were a big thing, and AI could render the code relationships for you.

I started with go and java (the two languages I was using in my job) and built AST parsers that would extract the relationships between the classes and functions and draw them with graphviz. Then I created a filter syntax based on regex to filter the graphs.

I never followed through on the idea to a production ready version, but it helped massively as a personal tool when working on unfamiliar codebases.

The site is still here, but lots of it is probably broken by now..
