> I know everyone thinks this is a bus

It's not a bus. It's an ordinary Uber driver with their own car, with multiple customers and a different, confusing pricing scheme. It's not Uber buying and operating their own fleet of branded vans, like SuperShuttle.[1]

How does the driver get paid? If it's a regular route, with regular times, it ought to be a regular job paid by the hour, regardless of whether the vehicle is empty or full. But that wouldn't be Uber's gig slavery system.

Perceived safety and comfort. Buses are safer than cars [1]. The problem is you might have someone who hasn’t managed their BO in a week sitting next to you, and that’s frankly happened enough time to me that I don’t take it in New York or the Bay Area anymore.

Running out of improvements after the first pass would prevent that. Who is to say this Alpha Evolve is not already obsolete, having already served its purpose?

Not to sound metaphysical or anything, but dependency on artificial intelligence seems to be something you would find at the peak of Mount Stupid (where the Darwin Awards are kept).

Passwords are terrible. They're Human Memorable Shared Secrets, it's "What if somebody who doesn't know the first thing about cryptography tried to invent secure authentication?" and should have died out last century yet here we are.

We have known for decades how to do better than that. The fact that at least twice a month (often much more) I read an HN comment saying passwords are great is like discovering most of your friends don't know about germ theory still. I feel so fucking tired.

With a Shared Secret system the person authenticating you can give away the fucking secret and we already know we live in a society where they will blame you and act as though there's nothing they should have done better - that's what "Identity theft" is - blaming other people for the fact you didn't do your job properly.

When you use Human Memorable secrets the humans try to remember them, which means they're usually very low quality, dog's name, favourite band, that sort of thing. Worse, since humans can't remember many things they usually choose only a few and re-use them, so now they're not only a Shared Secret they're also Reused which is even worse.

So then we end up with a whole pile of kludges to try to use "passwords" which aren't really memorable, losing most of the benefits yet still retaining most of the disadvantages. This is an awful situation to be in, it's taken a considerable amount of laziness and incompetence to achieve it.

I also always ask how it was measured and if they published that anywhere. It's also informative to ask how it compares to other similar projects at similar companies and how (when applicable) it compares to state of the art in academia.

Company size matters of course but it is nice to see how a decision got made and how the results compared to expectations. Was this done thoughtfully and rigorously? If it's just made up that comes through really really quickly as well.

My advice for all getting hired is to try to skip the recruiting pipeline. Yes it's hard and there is no silver bullet but the standard pipeline is a brutal gauntlet to go through and I'd rather spend the time building rapport with a hiring manager or future peer instead.
Show HN: Family Folder – Help your family remember everything, organise anything
by tonystaunton | 2025-05-14 18:57:11+00:00
Hi Show HN,

I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment.

This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between.

The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families.

Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant)

Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos.

If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family?

Thanks for taking a look!

– Tony

Honestly it's extremely annoying my device locks me out from my data - that would be third entry to my list:

* Nextcloud cannot access all files, despite many other file managers can - at least Fdroid version works.

* File manager cannot access /sdcard/android/data - inconvenient workaround via adb

* App is allowed to decide if I can (manually) take screenshot/ocr the screen - usually it's banking app, that wants me to remember some long number - then I write it on closest piece of paper - awesome security. No workaround as far as I know.

If I wanted such treatment I would buy ios :-|

I am in my 40s and yes seeing ones skills beeing Made obsolete is scary. But I still love the moment when I start with something new (language, tool, ...) whenever my job allowed me to dive into something new I am somehow grateful. And yes I do know the sentiment when I see something and catch myself thinking well this is the same as that which we had x years ago but actually it never really is or it is but now it really works. I dont fear AI will make me obsolete and for all the issues it has I am also astonished what is happening and want to know how it works. What other Industries offer this? That said I acknowledge that change comes with a lot of cognitive load which can cause Stress and anxiety and WE need ways to keep those in Check. I think this is also a Job of a company having to do with Tech, to Care for its workers (and everyone working in this industry)

Contrary to what your doctor friends might have told you, the AMA has no power to restrict the number of residency slots. They are a private membership organization with no regulatory or accreditation authority. At one time they did lobby Congress to restrict graduate medical education funding but have since reversed that position.

https://savegme.org/

A minority of funding does come from sources other than CMS. Teaching hospitals are largely free to add more residency slots if they want to. The fact that most hospitals don't do this indicates that GME programs are largely unprofitable.

It's really as simple as the fact that it's a much easier book to read, get through, and relate to than a lot of other books middle school and high school students have to read. It's not Shakespeare, it's not Dickens, it's not Dostoevsky. For a lot of us, it was a breath of fresh air (as was Hemingway's works).

Thanks! I have not tried anything other than English, not sure how good the LLMs are for that. Did you use Tesseract or Gemini?

Once the page structure is set up from the images (via the directory upload), you can upload new images for each page, but I didn't include an option to just create all the pages manually. It's a good idea. Going to add that...

It actually works more like a frontend talking to an API than 'inside' touches 'outside'. The container just reaches out over host.docker.internal to the Lume daemon running on your Mac. Lume is the only thing talking to Apple's Vz API and spinning up VMs. The container itself never gets direct low‑level access to the host's virtualization stack, so you're not giving Docker root powers over your Mac's hypervisor, just a handy layer that calls into a service with the right privileges

"On both Android & iOS/MacOS it's not that HDR is ignoring your screen brightness, but rather the brightness slider is controlling the SDR range and then yes HDR can exceed that"

Doesn't this mean HDR is ignoring my brightness setting? Looking at the Mac color profiles, the default HDR has some fixed max brightness regardless of the brightness slider. And it's very bright, 1600 nits vs the SDR max of 600 nits. At least I was able to pick another option capping HDR to 600, but that still allows HDR video to force my screen to its normal full brightness even if I dimmed it.

There isn’t a burden of proof on the internet.

You can say “I haven’t seen that effect, and therefore I disagree”. And I can’t stop you. If you haven’t seen that effect, perhaps your experience is more representative.

You can’t say “you don’t have a study to back up your account of your lived experience, and therefore you can’t make small scale explanatory suggestions based on your lived experience”.

Stature induced accidents is a false comparison unless you have witnessed short people driving erratically. Have you?

I again suggest that you are misattributing your feelings here. You are not upset because I haven’t linked a study, you are upset because I have said something that violates your morality. And this is the way that you know to push back. But your reason for pushing back is on a different dimension from what you are saying and probably what you are experiencing internally as well. Morality is a tricky thing.

This reminds me of Dwarf Fortress, a game famous for its auto-generated stories. Boatmurdered is one such story—it’s brutal, fascinating, it’s in this uncanny valley halfway between random and an actual story. And it definitely isn’t formulaic (except for the fact that everyone always dies in the end; the game’s motto is Losing is Fun).

Wow the resolution to your link [3] is infuriating:

> We assure you that we are doing our best to address the issue reported, however our product team has shifted work priority that doesn't include this issue. For now, we will be closing the issue as won't fix obsolete. If this issue currently still exists, we request that you log a new issue (...)

It's all possible excuses all at once: "Thank you for your issue, we are working on it. Also we have no intention to work on it and we are closing it, the problem probably doesn't exist anymore anyways, and if you think it does make sure to open a new issue for us to treat it with the same amount of respect".

There's nothing wrong with continuous learning. I knew that before choosing this career.

The issue with recent AI tech is that _I can't learn it_. I have to pay a lot of money (GPU renting or buying outrageous rigs) if I want to do even hello world AI stuff. The writing is on the wall, I will never be allowed to learn it, just to use it like a peasant.

This simply wasn't true before. I can read react code, roll my own, understand it. Same with any tech after the 90s. Heck, I can even do a primitive browser without having to buy GPU.

But AI is different. It will not allow you to learn past a certain point, and there is nothing you can do. And it's not about how smart or dedicated you are anymore. It's about money. Either you have huge datacenter money and you learn, or you don't and just play kids prompt guinea pig. It sucks.

Don't know what town you live in, but here in Seattle, very few bus routes have homeless people who ride them all day.

The vast majority don't.

The reason transit in this city sucks (still head and shoulders above the vast majority of the US) isn't because there's 12,000+ homeless people living in it[1], it's because the buses don't run frequently enough and because all the fucking single-occupant car traffic turns what would be a 20 minute bus ride into a 40 minute slog, and because you'd be insane to bike for your last-mile.

We ship perishables (cheese) in styrofoam coolers. When we have a damage claim, what usually happens is that the cooler is broken or even smashed completely, and the cheese got too warm and separated.

And then UPS won't pay out a claim, since they don't cover perishables, even when it's their fault for smashing the cooler. So we started self-insuring at $3 per order, plus we've learned how to package the cheese in the cooler better so it's less likely to break.

And as I mentioned it's very rare now to get a damaged one.

> absolute garbage devices

> damage school property

Look, we're mostly talking about elementary/middle school students here, right? So they're age 7-12 or so. Mostly boys, I would imagine.

So perhaps we've got an unjust proposition these days. Students often mark up their textbooks and their backpacks and vandalize their lockers to some degree. That's always going to happen -- it's a given for any school and any group of students.

Now we're routinely saddling each student with an advanced computing device. It may cost $300-500 to replace this thing. It is very high-tech and very delicate, and very resource-intensive, being a netbook type thing. And we say it's "school property" but the students themselves are responsible for lugging it around to every class, every day, doing homework on it, studying and taking notes on it, day in, day out.

I say that's nearly ridiculous. I say that in the United States, we shouldn't be uniformly training children from 7 years of age to be docile worker bees in the white-collar office. I say that a $500 high-tech device is an enormous responsibility for any child.

Now I had a similar experience in high school. The band director lent me a series of saxophones so that I could participate without my family purchasing one on our own. It was very kind of the school to lend out such equipment. A baritone sax could've cost five digits to replace, plus all the accessories. It was huge and unwieldy. I treated that thing gingerly, as if it were my own. I cleaned and maintained it in working condition. I returned it with regrets when I finished, having earned an academic letter for my service to the band.

But my cousin is a Kindergarten teacher. During the lockdowns, they put her kids on Zoom. They told her "now teach 'em". That's just beyond the pale. These are young children, and cannot just be babysat by someone on a screen. Now TikTok is their babysitter, and they're obeying TikTok more than their parents or their teachers. Perhaps that is a symptom of worse things going on.

Transit agencies are also capable of demand response. For example, you'll see more articulated busses at peak times in Austin. Also, large transit stops are used as queues to maintain consistent headways.

A great example of this in action happens each year for the Austin City Limits Festival [1]. A few routes have substantially more busses during those two weekends to deal with a couple hundred thousand extra passengers.

HDR is not referring to the scene’s range, and it doesn’t apply to film. It’s referring superficially but specifically to a digital process that improves on 8 bits/channel RGB images. And one of the original intents behind HDR was to capture pixels in absolute physical measurements like radiance, to enable a variety of post-processing workflows that are not available to film.

In our fast-paced world where quick decision-making skills and “trusting your gut” are glorified, there’s often a thin line between harmful overthinking and necessary analysis. The term “overthinking” has become ubiquitous in self-help literature, often vilified as the enemy of productivity and happiness. But is all deep thinking truly detrimental? When does careful analysis become paralyzing rumination?

That’s not bad.

I had to get from JFK to midtown during peak hours. It was Airtrain ($8.50) + LIRR to Woodside ($11) + Subway 7 train to midtown ($2.90) = $22.40. (I didn’t know LIRR had city ticket, it would have been $16.40.

But it took 1.5 hours.

If you see it as a tax, and the tax funds the service, and you like the service, why wouldn't you want to pay it?

About half of their liabilities were forgiven as part of the 2022 legislation. They still have debt and retirement liabilities, but those are more in line with other large services (private or public) now. However, they've each increased over 20% per year since 2022, which is quite a lot.

Personally, I would like to see a return of postal banking, in which case the postal service would pay out its profit to its accountholders.

If I understood, isn't this software only as useful as the llm powering it is? It sounds like something very useful, but either I'm missing something or it put into a loop and a validator a "please optimize this code". Useful, but maybe not as revolutionary as the underlying llm tech itself

Edit the white paper says this: AlphaEvolve employs an ensemble of large language models. Specifically, we utilize a combination of Gemini 2.0 Flash and Gemini 2.0 Pro. This ensemble approach allows us to balance computational throughput with the quality of generated solutions. Gemini 2.0 Flash, with its lower latency, enables a higher rate of candidate generation, increasing the number of ideas explored per unit of time. Concurrently, Gemini 2.0 Pro, possessing greater capabilities, provides occasional, higher-quality suggestions that can significantly advance the evolutionary search and potentially lead to breakthroughs. This strategic mix optimizes the overall discovery process by maximizing the volume of evaluated ideas while retaining the potential for substantial improvements driven by the more powerful model.

So, I remain of my opinion before. Furthermore, in the paper they don't present it as something extraordinary as some people here say it is, but as an evolution of another existing software, funsearch

That’s a strange claim because the first digital HDR capture devices were film scanners (for example the Cineon equipment used by the motion picture industry in the 1990s).

Film provided a higher dynamic range than digital sensors, and professionals wanted to capture that for image editing.

Sure, it wasn’t terribly deep HDR by today’s standards. Cineon used 10 bits per channel with the white point at coding value 685 (and a log color space). That’s still a lot more range and superwhite latitude than you got with standard 8-bpc YUV video.

Correct. Apple's licensing requires macOS to run on Apple hardware, and limits you to 2 concurrent macOS VMs per host. This is enforced by the Apple Vz framework itself. Some KVM-based solutions bypass these checks, but they aren’t compliant for production use.

There’s instead no such limitation when running Linux VMs on a macOS host.

I think about the Ansel Adams zone system

https://www.kimhildebrand.com/how-to-use-the-zone-system/

where my interpretation is colored by the experience of making high quality prints and viewing them under different conditions, particularly poor illumination quality but you could also count "small handheld game console", "halftone screened and printed on newsprint" as other degraded conditions. In those cases you might imagine that the eye can only differentiate between 11 tones so even if an image has finer detail it ought to connect well with people if colors were quantized. (I think about concept art from Pokémon Sun and Moon which looked great printed with a thermal printer because it was designed to look great on a cheap screen.)

In my mind, the ideal image would look good quantized to 11 zones but also has interesting detail in texture in 9 of the zones (extreme white and black don't show texture). That's a bit of an oversimplification (maybe a shot outdoors in the snow is going to trend really bright, maybe for artistic reasons you want things to be really dark, ...) but Ansel Adams manually "tone mapped" his images using dodging, burning and similar techniques to make it so.

I don't know anything about compliers, so this note about reasons and intentions from the presentation link was helpful to me:

> YJIT can make Ruby code run faster, but this is a balancing act, because the JIT compiler itself must consume both memory and CPU cycles to compile and optimize your code while it is running. Furthermore, in large-scale production environments such as those of GitHub, Shopify and Stripe, we end up in a situation where YJIT is compiling the same code over and over again on a very large number of servers, which seems very inefficient.

> In this presentation, we will go over the design of ZJIT, a next generation Ruby JIT which aims to save and reuse compiled code between executions. We hope that this will help us eliminate duplicated work while also allowing the compiler to spend more time optimizing code so that we can get better performance.

Seems pretty cool. I haven't run into any these limitations in my own usage really, but I'm working at very small scales.

It also can actually allow you to identify positions within the image at a greater resolution than the pixels, or even light itself, would otherwise allow.

In microscopy, this is called 'super-resolution'. You can take many images over and over, and while the light itself is 100s of nanometers large, you actually can calculate the centroid of whatever is producing that light with greater resolution than the size of the light itself.

https://en.wikipedia.org/wiki/Super-resolution_imaging
