- Comment on ‘My whole library is wiped out’: what it means to own movies and TV in the age of streaming services 5 weeks ago:
What’s funny is that’s how it started. Apple sold movies as early as 2007 before Netflix or Amazon video or whatever and expected you to host the files locally either on your computer or your AppleTV (which had a hard disk drive at the time) and stream it locally over iTunes. If you lost the file, that was supposed to be it.
Of course, you still had to authenticate your files with the DRM service, and eventually they moved libraries online and gave you streaming access to any files you had purchased.

- Comment on I’d like to build a ducting system to actively push air from one room to another. Is that a thing? 5 weeks ago:
Should have been more precise. I have a funny situation. My house has had four major remodels performed over the past 80 years. One of them involved extending the roof and totally covering a chimney (there is another chimney elsewhere in the house). Rather than remove the chimney, they built around it including adding a closet on the middle floor. The closet is wider than the chimney, but the whole thing is framed out as a rectangle, so I have like 1x2’ of empty space leading from my attic to the basement ceiling.
So not need for liners.
I don’t really see why you would want to pull air from the attic, but you seem to feel you would need to.
I’m by no means an HVAC expert, but I was thinking that pulling hot air from the hottest point in the house (attic room ceiling) would provide the best circulation. Thinking more about it, I think I’d be better off having it be one-directional if only so I can install a filter to keep it from filling up with dust. I can convince myself that either direction is the better option. Maybe I’ll install the blower somewhere in the middle where it’s easy to access.
Thanks for the advice!

They’re not destroying anything. The car can still be upgraded by either the current owner or the next one.
Ironically, you’re advocating for going through the effort of physically removing batteries to sell at a lower price. That’s closer to your headlight analogy. The car was designed to have a specific battery size, and the equipment is already built to make that size. It is not easy to physically alter the batteries at scale.

Because there is no inherent link between the cost of manufacturing a product and the price at which it’s sold.
If they can sell it cheaper then do so. If they can’t don’t.
So if Tesla develops new technology that allows them to produce cars cheaper, should they be required to lower the sale price of their vehicles?

Why does that make it worse?
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 5 weeks ago:
That just means they could be selling the full range version cheaper.
No. The additional price of the full-range version is partially subsidizing the lower priced version. People are willing to pay the current price for the longer range version, why would they lower the price?
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
I mean, they can just give the batteries away for free too, but most businesses have a vested interest in making money. In Tesla’s case, they also have an interest in paying back the massive investment it took to get the first car off the lot.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
proprietary software gives the developer power over their users.
Agree here, but that’s a much larger issue than just this particular pricing structure.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
Sure:
It’s cheaper to manufacture and maintain a single version of a product. It’s cheaper to ship and store a single version of a product. It’s also easier to adapt to quickly changing market needs if you don’t need to spend six months spinning up a production line for a different version of a product.
Also, the existing market for low-range EVs might not be large enough to justify the expense of maintaining a separate line.
If there is competition in the space, it’s safe to assume that some portion of these savings are passed on to the customer to better edge out competitors over price.
If you want to be very charitable: wealthier people who can afford the full-range version are partially subsidizing the lower range (tighter margin) version for more budget-conscious consumers.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
You are not required to purchase your vehicle from Tesla. I mean, we’re butting up against the primary tenets of capitalism here. I’m a socialist personally, but if there’s one thing that capitalism is supposed to do well in theory, it’s find market efficiencies. Tesla appears to have found one here. If anybody else could sell a non-software locked smaller-battery version of a similar vehicle for a lower price, people would buy that one instead.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
When it comes to things that are trivial to include but locked behind exorbitant paywalls (i.e. heated seats), I agree.
However, range/battery capacity is the primary price differentiator for EVs and also the primary cost for manufacturing. Finding a way to offer options that suit the needs of different people at varying prices just allows more people to enter the market.
to become the de facto standard
I feel like it might be nice to have a sliding scale of ranges available for people who have a sliding scale of needs. If I need a second car strictly for my 20 mile commute, it might be nice to have an option to pay less for 100 miles of range over 200. And I assume if a market is established for low-range EVs, manufacturers will compete with each other on how to deliver that for the best price. Perhaps if the market is large enough, Tesla will find it better to actually remove the extra batteries and put them in other cars.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
It’s only cheaper because they inflated the price from a limitation they created.
TIL Tesla has a 100% monopoly over the electric vehicle market space.
Tesla is offering a wider variety of products at more diverse prices to try to better fit the needs of a larger portion of customers. They must have determined that it was cheaper overall to do it this way rather than physically rip the batteries out of the vehicles or they wouldn’t do it.
to create an artificial divide to upsell people on the “”higher”” capacity.
I mean, isn’t not offering a cheaper version at all already upselling? When the F-150 Lightning came out, people had a really hard time finding the standard range version because dealers didn’t want to sell a lower trim version of the car with lower commission.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
You don’t have to buy the car. People aren’t getting conned here… They would buy a more expensive version of the car with a higher range if they thought that would suit their needs.

It’s funny how frequently this business model is used in the digital space, but when it comes to physical hardware, people freak.
Like look at movies. Does anybody really think it costs substantially more to deliver the 4K version of a product over the HD version? Everything, Everywhere, All At Once is $12 on Blu-ray on Amazon. It’s $20 on 4k UHD.
The movie was mastered at 4k or higher, so why not just give you the UHD version with the Blu-ray version? The physical disc can’t cost more than a few cents to manufacture.
It’s because some people have decided they don’t need 4k and are happy to take a shittier version of the product for a lower price.
Don’t get me started how much people hate when content is included on the game disc locked behind a paywall yet somehow have less of an issue when there’s day 1 downloadable content also locked behind a paywall.

Or they could not reduce it for the same production cost. No money is saved by tasking an employee to develop the battery nerf.
Yes, but perhaps some money is saved by not having to manage multiple production lines for multiple battery capacities and also having to predict how many of each capacity is going to sell so you’re not stuck with cars nobody wants?
There are no benefits. You could simply unplug at 80%.
Right, after you just paid more for battery that you’ve decided not to use. The benefit is that it’s cheaper for the customer.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
It’s possible that these vehicles are already built and Tesla needs a way to entice budget conscious buyers to clear out their inventory.
- Comment on Elon Musk reveals Tesla software-locked cheapest Model Y, offers 40-60 more miles of range 1 month ago:
It’s tricky. It’s not like BMW locking heated seats, a trivial feature, to nickel and dime the owner out of $300.
Reducing the battery capacity severely alters the value of the car possibly dropping it into the range of more budget conscious buyers.
There are benefits too. Less wear on the battery by not using its whole range, faster charging to “100%,” and more potential value when it comes time to sell should the buyer want to unlock the extra range.
Leave it to Tesla though to bungle the PR and completely lose the narrative.

- Comment on Building DIY a smart doorbell but would appreciate some help with the power and wiring 1 month ago:
Your drawing is a little confusing. Here’s what you need:
There’s nothing special about a setup with a light in the button. It’s literally just an incandescent bulb across the button. If you connect your circuit across the button terminals, it’ll work fine.
The 4 diodes in a loop is a “full bridge rectifier” that gives you DC from AC. The 5V regulator could be something like an LM7805.
The “large capacitor” is to keep power applied while the button is pressed, though you might be better off in that case with some small onboard battery. You just have to make sure that your battery charging circuit doesn’t draw too much power.
- Comment on Building DIY a smart doorbell but would appreciate some help with the power and wiring 1 month ago:
So a doorbell transformer steps 120VAC down to a lower AC voltage. That’s what you’re measuring (surprised you can’t tell if it’s AC. Your multimeter should have an AC/DC setting).
The circuit puts the transformer, the button, and the bell (classically an electronagnet that accelerates the hammer) in series. When you close the switch (push the button) the hammer strikes the bell.
An electromagnet is just a coil of wire, and it is possible to pass a small amount of current through it without activating the hammer. If you’ve ever seen a doorbell with a light up button, the light bulb is placed in parallel with the button. That way it’s always on drawing a small amount of current. It also explains why the light switches off when you press the button. You’re shorting across the bulb, so it’s voltage is zero.
If you want to use this power for an electronics project, you’ll need to find a way to draw just a small amount of power from the transformer. It has to be very small or you’ll activate the hammer.
Drop a full bridge rectifier in parallel with the button, then a bunch of caps to give you a steady-ish voltage and then some kind of voltage regulator to make it useable.
Just remember that you can’t draw too much power, and you’ll lose that power whenever the button is pressed.

That shouldn’t be the case. I’d look into getting this fixed properly before spending a ton of money for new hardware that you may not actually need. It smells like to me that encode or decode part aren’t actually being done in hardware here.
Right you are!
Dug into it a little more. There were some ffmpeg flags that weren’t being enabled by the latest release of Photoprism. Had to move to the test build. github.com/photoprism/photoprism/…/4093
While it’s faster than real time now, Photoprism still won’t start streaming until the preview is fully generated, so longer video clips can take a minute or two to start playing. It only has to happen once per file, but it’s still annoying. There’s a feature to pre-transcode video, but it’s only to get in to a streamable format. It doesn’t check bitrate/size until you actually start to play.
I might write a script to pre-generate the preview files, but either way, I don’t think I need to upgrade the server quite yet.
