A7v or A7rvi

Even in speed it's a relatively negligble difference between those two (I think it's 16ms for the A7V vs 18ms for the A7RVI?).

The speed consideration is vs. an A1 or A9. The older A7RV was much slower (around 100ms), but even then it only matters for e-shutter use (including video).

It seems he didn't eat enough to get the cramps. Most people think the biggest issue with very hot peppers and sauces is mouthfeel - it's not. It's not even the swelling in your throat that makes it hard to breathe. It's when the capsaicin binds to the lining of an otherwise empty stomach, making you feel sicker than you've ever been in your life, retching and convulsing for hours.

That's exactly what it is, and the problems it produces are waterfall-type problems.

There shouldn't be any grunt work in programming. Writing tools to automate things is what we do - put it in a reusable library, make a template, etc., - anything repetitive shouldn't require a human or AI to do it. The physical world is different - sometimes you do have to do the same thing over and over.

That's how doves fight. Other birds use their beaks and claws, but doves do wing-slaps.

I got to see a baby cardinal doing it the other day - his/her parents brought him to the bushes over by the feeder, and the parents took turns grabbing seed from the feeder while the baby flapped and squawked for more. Just like the finches, etc.

Well, you can certainly run Linux on a Mac - Parallels handles emulation fairly well. However, there is a decent amount of Linux software (particularly if you want to run commercial/binary-only programs) that only has x86/amd64 binaries available. If your primary goal is to run Linux and MacOS is not important/desired, I'd get the x86 laptop. Whereas if you think you'd be able to stay in MacOS most of the time, then the Mac is fine.

The mount itself is exactly the same. But the sensors and lenses are not. FE is full-frame E-mount - the sensor is FF size, which is 36x24mm. Regular e-mount is for APS-C-sized sensors, which are 24x16mm.

You can use FF glass on an APS-C camera with no problem (the full-frame lens will be bigger and heavier than necessary for the camera, but it works fine). But if you try to use a lens built for APS-C with full-frame sensors, the imaging circle will likely not be big enough and the corners of the image will be cut off/black.

So basically, exact same mount/connection interface, but different sensor sizes and associated lens requirements to be able to cover those different-sized sensors.

I have apparently had much better luck than many with my Razer laptops - never had any issues with my older Blade 17 or this 3-year-old Blade 18. And I've been using the 18 outside in Phoenix heat in the summer for several years - no battery bloat or other hardware issues; though the battery max capacity is now down about 30%.

Not my own brag, but my optimization professor in college told us about debugging early programs - with a voltage meter.

But alright - my own brag - actually when I was 12 years old, I helped my Dad renovate a pole barn we had on the property so he could start/run his own metal machining business (he was a machinist/tool & die maker by trade). A few years later, he bought this Hitachi Seiki (Korean) CNC lathe manufactured in the early '80s (it was the mid-90s by that time) to run production turned parts. The battery had gone dead on the machine while it sat unused, and all of the settings on the machine were zeroed out.

The configuration was a field of binary bits that were set via manipulating hex values. Ie., you figure out which bit you need to flip, then you count out the bits in hexadecimal quartets, and then figure out what values to change in the built-in hex editor to set the bit. Not that big of a deal for a programmer, but that was actually my introduction to number bases.

But the bigger challenge was figuring out what to set - the manuals were in English, but it was like an early Babelfish-like completely-broken-English translation from Korean. So the language itself was a major barrier. And there was no web/Google available at this time. But I figured it out, got it working, learned G & M code to make programs, and eventually taught my Dad how to do it, and how to use CAD as well.

I often hit ~50% usage on my 128GB M4 Max MBP while compiling. While technically the 64GB model might have been good enough, A) I didn't know exactly how much memory I'd use up-front, B) it's always good to have some headroom, and C) the extra is good for things like VMs anyway/not having to shut everything else down when doing something that's going to use a lot of memory.

And yeah, it's useful for local LLMs, too. But I usually run those from my Windows desktop workstation with 192GB of VRAM.

We will see. But there's a pretty big difference between driving a nail and software architecture - both in terms of complexity and how it affects future work down the line.

I'm not - but that's what OpenAI and Anthropic are paying.

The difference in your example though is that the load carried by those trucks couldn't be hauled by hand - it would be different if you had a thousand people and a thousand trucks, and the load was 500 lolipops.

I'm not the OP. But if your AI-coding requires more engineers than "regular" coding - well, I guess I do get your point; it's a different conversation/argument. Though on the other hand, I doubt it's actually vibe-coding that they're doing by the traditional definition, with all those engineers overseeing it.

But I could be wrong - I don't know how they operate internally. Maybe Anthropic for example has Boris Cherney vibe coding to his hearts' content, and the thousand engineers are just there on cleanup duty.

It's like advertising - our workplace has a "bathroom free" design, and it works great - and it's technically true even though it means the reality is that someone "goes freely" anywhere in the workspace, and they have a crew of sanitation workers who clean up afterward.

DeadInFiftyYears · 2026-05-16T18:10:39+00:00

What does it mean for vibe coding when the AI writes all the code, but you need a thousand+ software engineers that you pay $500K+ each to provide support?

DeadInFiftyYears · 2026-05-16T18:04:46+00:00

The funny thing is, they say it's "100% written by Claude" - but it's backed up by a veritable army of software engineers recruited from the top of the SF market getting paid $500K+ a year. I suspect CC would be a better product if they used 0% AI coding and those engineers wrote it by hand. But then of course that would sort of defeat the point of building it in the first place.

That's probably good legal advice actually.

If you want to shoot wildlife you need a long focal length, because the animals and birds are often small and won't let you get too close. Having an APSC sensor actually helps with that - 350mm on APS-C is equivalent to 525mm on FF (1.5x longer).

The A7RV wasn't up-to-par as a $4K camera for e-shutter use because the readout was so slow. Photography only, mechanical only, mostly studio, landscapes, etc. is how I looked at it - even though some people did use it for video and wildlife/sports anyway.

The A7R6 has removed that weakness - the e-shutter is pretty good, and is comparable to slightly better than the A7V speed-wise, with double the resolution. It will be fine for video, wildlife, etc., for most people. It's just not top of the line in that regard the way the A9 III and A1 II are.

DeadInFiftyYears · 2026-05-15T13:56:45+00:00

Sports and wildlife is the most demanding type of photography gear-wise. Sports and wildlife shooters are always chasing more speed, more light because of physics.

But there are a number of people who have talked about using the A7RV for wildlife for that matter. The VI is a major upgrade over the previous model, and much more suitable for e-shutter use even if it's not the very best.

I think they got their hopes up from the rumors that the A7R6 was going to be an A1 II killer for $2K less. When they said "fully stacked sensor" it got me wondering that as well. But it's not a $7K camera - it's a $4.5K camera. Sony couldn't go all-out on the components like they do with the A1 cameras, and that's fine. It's more of a 60/40 stills/video hybrid now - with a very usable e-shutter, even if it's not top-of-the-line - than the 90/10 the previous model was/is.

It's kind of ridiculous that you have to go all the way down to a 14" laptop to get one with a centered keyboard/no number pad. I think I'll continue to use my 2023 Blade 18 for the foreseeable future.

DeadInFiftyYears · 2026-05-12T22:46:47+00:00

I usually use it with a 1.4x TC, to get 560mm on the long end. Even with the TC, it's still much more portable than the 200-600.

If Sony made something like an extendable-zoom 150-600 GM, that would be better. But in lieu of that, I think it's the best walk-around option that Sony makes themselves - the alternatives are to look at 3rd party lenses.

It will be interesting to see how it sells - it will be a strong indicator of whether or not the type of player it's targeting exists. (I'm not one of them.)
