well, why don't you bring your physics and human anatomy arguing-from-first-principles over to wikipedia and let's see how long your changes last on that camera page :) good luck!

https://en.wikipedia.org/wiki/Single-lens_reflex_camera

opening paragraph

"In photography, a single-lens reflex camera (SLR) is a type of camera that uses a mirror and prism system to allow photographers to view through the lens and see exactly what will be captured... SLR technology played a crucial role in the evolution of modern photography...the rise of mirrorless cameras in the 2010s has led to a decline in SLR use and production. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image."

what you see through the viewfinder is what the camera will take a picture of; you can change lenses so it is not always neutral. but if the zoom of the lens it neutral, what you will see through the viewfinder is neutral, and that occurs at 50mm for a 35mm camera

the video was long and depressingly commercialized, so I went to Wikipedia to just get the basic idea about this and im blown away how long cubesats have been around and fairly easily available.

https://en.wikipedia.org/wiki/CubeSat

> As of December 2023, more than 2,300 CubeSats have been launched. > Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, and by 2014 most newly deployed CubeSats were for commercial or amateur projects.[3]

2013?!?! Regular academics have been putting little cubes into space with whatever they want since 1998! amateurs have been doing it for more than eleven years?? There's 2300 of them! this is all blowing my mind that space is even this accessible to people who don't work for NASA, ESA or SpaceX.

I think this might be a longstanding "bug", but I have also not had any luck on my android using the screen recorder to record device audio from a browser (either chromium or firefox). It used to partially work using the mic to record the speakers, but currently it sounds like it does processing to subtract away the original signal; I hear mostly silence with occasional garbled artifacts resembling the original audio.

Our front end team doesn’t settle for ONE framework - they have several, all in the same application’s code base. There’s React, AngularJS, Angular, Vue (I think they started on that??) and even a bit of Jquery.

Is it an SPA? Well it’s an SPA per framework per page!

No one has the patience to port all the old code, and no one has any leadership to guide them. They’re just adding in flavor of the month and making it work somehow (kinda, well depends on who you talk to)

If the DNS entries for the certificates have a very short TTLs (i.e., 2 minutes) then you wouldn't need explicit revocation infrastructure. It would probably take more than 2 minutes for CRLs or OSCP changes to propagate anyway.

(I'm not necessarily in favour of this, I just don't see the revocation part as being the main issue.)

Agree. Revolutionary tech happens, perhaps, once a decade. Apple's though is their own biggest enemy because there is so much gravity for these big roll-outs they have a couple times a year (typically Macs and then Phones+).

That's a lot of hyped, flashy events between anything really Earth shattering.

Maybe we miss when Apple was boring and new machines just rolled out with little more than a press release and a spread in MacWorld magazine.

I don’t mind the visual appearance of iOS 26. My main gripe is that this update introduces some pointless additional taps for common interactions.

Here’s some of the UX regressions:

- Apple Music: the “next track” button is only visible if the tab bar is expanded. So now we have to scroll or tap, wait for an animation and then click next. - Web views search web for selected text: previously we could highlight, swipe the action menu and then tap the button. Now we have to highlight, tap the small arrow, wait for the horizontal list to animate into a vertical list, tap the button. They removed the ability to swipe the action menu. - Tab bars: since 2007, you could change tabs with one tap. Now it’s one or two taps, depending on whether it’s collapsed or expanded.

Thanks man, appreciate it, and kudos for stopping.

I might quit, I guess, when my fiancee has to for pregnancy, should it eventually stop being funny to tell her how wonderful each individual cigarette I smoke is. But I really, really love smoking - more than any of my other hobbies, wholesome or otherwise.

I'm sure that'll change, and I'll look that book up if and when it does. Thanks again.

React DX is probably the worst DX of all frontend frameworks I've ever seen. All kinds of confusing concepts (hooks, memo, props passing, class style vs function style, an entire new "language" like JSX which you then first need to install an IDE extension for) and you cant even begin a react project most of the time without using some kind of react starter template because building this thing is so hugely complex that people just give up. Then you constantly run into issues of double rendering with reactjs which is quite hard to debug. I was hoping for something tiny like https://www.arrow-js.com/ taking off but the creator doesn't really work on it.

Unfortunately, the only real comparison for iOS is past versions of iOS; until that changes I don’t see things getting better in any stable way.

iOS 26 actually has a lot of great features and convergence with the rest of the ecosystem (e.g. preview is awesome). But it lacks the polish that Apple has a reputation for; unfortunately 50% worse polish for Apple is still significantly better than Android and Windows. There just aren’t greener pastures to move to.

> Humans have thoroughly evaluated LLMs and discovered many patterns that very cleanly map to what they would consider real-world concepts

Well yes, humans have real-world concepts.

> Semantic properties do not require any human-level understanding

Strawman.

> a Python script has specific semantics one may use to discuss its properties

These are human-attributed semantics. To say that a static script "has" semantics is a category mistake--certainly it doesn't "have" them the way LLMs are purported by the OP to have concepts.

> it has become increasingly clear that LLMs can reason (as in derive knowable facts, extract logical conclusions, compare it to different alternatives

These are highly controversial claims. LLMs present conclusions textually that are implicit in the training data. To get from there to the claim that they can reason is a huge leap. Certainly we know (from studies by Anthropic and elsewhere) that the reasoning steps that LLMs claim to go through are not actual states of the LLM.

I'm not going to say more about this ... it has been discussed at length in the academic literature.

Fuck. This is what I get for posting on 3 hours of sleep. My hallucinated bullshit came out so close to actual that it looked correct enough.

3.2v nominal per cell, 305Ah capacity: .976kWh per each. Call it .98. Not 980Ah, but 0.980 kWh.

.98 * 22 = 21.56kWh total pack cap.

*0.6 = 12.936 kWh available before conversion losses

We burn about 11kWh daily, so there's about a day in a full battery. Spring/mid summer worked well, but lately we aren't managing to store enough to get through the night, so I will probably add another 10 panels (5s2p) once I can find a grand I don't need.

Could you elaborate a bit?

Don’t mean to dig in on this, but I googled for some chain of custody / evidence tracking SaaS and found: QueTel, SAFE by Tracker Products, CustodyChain, and BlazeStack.

Just curious. I probably have to read up on what chain of custody really entails.

the basis of ghost kitchens started with one restaurant being cloned by the same restaurant to serve as a preparation nexus for their own menu to get local coverage and gain economies as the restaurant ramped up. Later pirate restaurants that were clones that copied the menu and snapped up the order - often assisted by delivery companies that had the stats. Later these grew larger, multi menu clones, often with 3-6 restaurant clones in one spot. Then someone got greedy, and the rents for these spaces destroyed their economic basis, and the city got greedy, rubbing their oily hands together to get taxes, levy code shit etc. The original restaurants lawyered up and the ghost kitchens became anonymous - and Oh yes, COVID was over

AirPods (and Bose QuietComfort) make me dizzy/nauseous.

Also, they don’t have decent passive noise cancellation, so they’re not appropriate for mowing the lawn, etc.

My Sennheiser ear buds solve all these problems for a much lower price, and their sound quality is much better than the last pair of AirPods I tried.

To each their own, I guess.

Or course.

Case in point, iPads don't have headphone jacks. While these devices are very capable of audio production, that's a joke while using Bluetooth.

But that's not Apple's concern. Airpods sell billions of dollars worth every year.

Every other phone manufacturer said ooh, cool and instead of getting pro level audio in my 1000$ Android phone I have to settle for Bluetooth which still hasn't caught up.

Airpods, and there cheaper friends are , as the article mentions, e-waste. Maybe you get 2 years out of them.

My analog headphones, with some light maintenance ( and a detachable cable) may last decades.

At this point Apple could come out with a 2000$ Audiophile line of phones with the jack and I'd buy one. But they won't.

This is really cool — the snapshotting approach with CRIU feels like the missing piece that serverless was never able to solve cleanly. Being able to “pause” work across long waits without hacks is huge. Curious how you see this stacking up against Temporal or LangGraph — feels like you’re aiming at the same pain points but from a more infra-first angle.

>IoT security is generally terrible

I think IoT demands a rethink of security.

Like sometimes I want IoT devices to just bloody connect, and if I have to use a published exploit that circumvents online only requirements I will do it.

But some people do genuinely have use cases for cloud speaking IoT stuff.

Really I think the device should ask at first run, and then burn in your response and act only in the selected mode. If you want it to require Cloud MFA, thats an option, if you want to piss python at your lightbulb to make it blink, then thats where it lives permanently.

Scary stuff. But if we only use mass facial-recognition to catch “the bad guys” then that’s OK, right? It’s not totalitarian or authoritarian at all, right? When a majority of voters want it, that’s democracy, right?

> it’s a company that I feel has lost its alignment with me and other long-time Apple users and customers.

When OS X debuted there was a daytime radio talk show in my area called “The Computer Guys.” They capably covered all sorts of computing topics, but were clearly long-time Apple dudes. And they spent weeks complaining about what a disaster OS X was. The Dock was useless and violated Apple’s HIG. The Finder made all the same mistakes as Windows did. And a text terminal? Like DOS?? Who the hell is ever going to want to use that on a Mac?

Going even farther back, it was long-time dedicated Apple users who booed when Jobs announced the deal with Microsoft.

Being a long-time dedicated Apple user is a shitty job. You don’t get paid, have no input, and are constantly disappointed. And Apple does not care about you.

I strongly suggest people should throw this notion away. It does not matter how long you’ve bought from a big company, they owe you nothing. If the latest product seems good, buy it. If not, don’t. Any more emotional investment than that is going to cause pointless unhappiness.

Save your customer loyalty energy for businesses where you can actually establish a connection, like a restaurant you like, or a local handyman.

> Insulated containers are not rocket science.

You often want the opposite of insulation. Food continues to cook in the container, things get soggy, etc. Each dish and even ingredient can have different ideal packaging requirements. It's not something that really scales well. It's part of why menus like McDonalds' remained stable and relatively small over a period of decades. Notice how their fries are served in a specialty designed container that's open, which avoids them becoming soggy.

IIUC, there have been some efforts to compartmentalize/isolate closed baseband, when you can work on the hardware.

Separate from baseband, the (sub)device closed firmware blobs are non-ideal, and eventually you'd want open source even for those, but maybe don't have to be a high priority. Mainlined open source for corresponding drivers are much higher priority. Even Debian now tolerates such blobs.)

I realize we're talking about Airpods, but hot swappable batteries don't make sense to me either anymore. I seem to have power almost everywhere.

My phone spends a surprising amount of time on a charger. Most of the day while I'm at home, it's on a charger. I used to keep one at the office on my desk. The car has a charger too, and CarPlay so you might as well plug it in.

I'm not sure if it's a coping mechanism for poor battery life or just convenience.

For long days outdoors, I've also got a booster pack in the car with USB ports and an inverter (120V) that gets some use.

As someone willing to put up with all manner of nonsense (overpriced/underpowered hardware, clunky UI, endless troubleshooting), battery life on mobile Linux devices alone prevents me from using them in the real world.

Is there a single Linux phone/tablet that can last an 8 hour day of actual use? Librem/Pinephone/Juno can't. My uConsole can't. Different category, but my MNT mini laptop lasts like 4 hours and can't be left in standby for too long or it drains to zero.

Meanwhile, it's been 10+ years since I've worried about daily battery life on mainstream mobile devices, even my 3-5 year old ones. I can fall asleep with Youtube playing and it's still playing when I wake up. I'm certainly not here to dunk on Linux phones. I want one! But if someone willing to put forth above average effort to use these devices can't realistically daily drive them, who can?

My bill was €316 bimonthly at €0.31/kWh before I put in panels. Last bill covering the two sunniest months I've ever seen in Western Europe was €100 exactly, of which in excess of €50 was the standing charge that is due regardless. The remaining ~€25/mo overage is the delta of our demand and the inverter's peak output. Next purchase will be more panels; another inverter would offer only marginal gains.

Most Domino’s were/are almost always delivery. Yes you can go pick up your pizza but most people don’t.

When I worked there they sold pizza and Coke. That was it. No breadsticks, no wings, no salads. One kind of crust, two size options. And by Coke I mean Coca Cola Classic in 16oz glass bottles. No Diet Coke, no sprite, nothing else. It was pure efficiency by elimination.

The drivers were all employees then, too. Not gig workers. No idea if that’s still the case.

Are you really surprised though or are you talking about the HN reading subset of your "many people"?

Coz I would absolutely 100% not be surprised for your average consumer.

For your average HN reader I would hope they treat whatever their ISP gave them as just some dumb "switch" type device that sits outside their trusted network and handles nothing but encrypted traffic. Like my ISPs device definitely does have a WiFi and such, which I disabled. I treat it as a bridge / modem and it's definitely not part of my "inner circle". Hasn't been in 25 years.

Yeah, sorry. I wrote this in a completely upside down way.

the Google Messages on Android will show:

to "Too many squirrels in this town"

Which is the same way it shows if someone thumbs ups a message you never received.

Mcdonalds is really good. Even if the cost is an extra few pounds and increased chance of getting cancer.

If Mcdonalds starts taking a backseat, it’ll because its no longer really good. And, to be fair: I’ve started to see this happen. Mcdonalds & Coca-Cola have totally taken over the food industry world, and they’ve proven to make quite poor nutritional decisions. All great empires are destroyed from the inside, not out, and I think its possible Coca cola could do this to Mcdonalds. But also even as Coca-Cola seppukus itself, people will likely just fallback to Mcdonalds on Pepsi (or, there’s Pepsi Zero Sugar that’s I think still under development, but might end up being big).

> If people find it useful but enterprise adoption is lagging, doesn't that indicate there's still a big upside?

It could indicate that many people find it more of an entertainment product than a tool, and those are often harder to monetize. You've got ads, and that's about it, and puts a probable cap on your monthly revenue per user that's less than most of the subscription prices these companies are trying to get (especially in non-USA countries).

(I find it way more of a tool and basically don't use it outside of work... but I see a LOT of AI pics and videos in discord and forums and such.)

React isn't winning by default. It's been so effective, so well designed that it's lived long enough to become the defacto standard... and the villian.

Claiming React is slowing innovation is an absolutely bonkers take when React is essentially the only sane stable choice in a sea of "me too" frameworks and libraries with conflicting and confusing design choices.

Yeah, I have few bricked devices which reached the your goal.

No, I cannot rely on the app sandbox. If someone else controls a device, then this device can be used against me.

Your antivirus, scanner or not, is useless on your device for you.

My antivirus on my device is useful for me. It works fine on GrapheneOS (Pixel 6), but banned by Google on Pixel 5, which is not supported by Google with security updates. WTF?

Yeah, this is a really annoying thing about how hooks work. For whatever reason (I'm sure they have a great reason) React can't do hook state book-keeping correctly without tying it to a function component lifecycle.

I think you actually can conditionally render a hook but that choice has to last for the entire rendered lifetime of the component. But that doesn't really help you when your user can switch between them.

> And a text terminal? Like DOS?? Who the hell is ever going to want to use that on a Mac?

Me. I have to use a Mac at work, and I use the text terminal more than anything else on the computer. It doesn't help that Mac's don't have a good UI, everything is hidden behind extra key-presses, and switching between windows is a PAIN.

On a mac every window for an app is considered the same, so there's no concept of switching between windows (except with special hidden key presses).

When a window is in the background it doesn't receive clicks, so you have to click on it twice.

The menubar of a non-active window doesn't exist, so you need an extra click, first to activate the window, then to go find its menubar and do an action.

It's just a bad UI.

Bikes used to be fairly standardized to where you could do most builds and maintenance at home . Now there are hundreds of subcategories , parts are bespoke to the bike , and standards have all been obliterated. Duty cycles are very short . Brakes , BB , headsets , bars , axles , cassettes , freewheels each have half a dozen formats . Bikes are practically disposable. Costs are up over 10 years and quality on many aspects has declined .

There are hundreds of boutique brands and almost none are making any money. No one sensibly pays msrp you can find bikes 60% off easily.

When you think about productivity , in terms of how much utility can be produced by one person, it’s obviously declining . We have more tools, but the bulk of the effort has gone into getting attention rather than providing utility . Even the product development is more about marketing than utility

When I worked there they had hot boxes drivers would carry in their car. There was an alcohol burner in it that somewhat kept it warm. They switched to insulated bags about a year after I started.

The stores usually had one or two company cars, a hatchback like a Ford Escort, painted up with the Domino’s logo. It was not equipped with any special pizza warmer. But most drivers used their own car. They got an hourly wage, a percentage of the order total if they used their own car, and tips.

Apple is a hardware company that makes lifestyle products. Why isn't their hardware appealing to me? Why can't it be?

In a competitive economy, phrases like this should a last resort, used to describe only the most decrepit and unjustifiable businesses. If nothing they can announce will interest me, then what are they even selling? A religion? A service? Certainly not a commodity, apparently nothing I need.
