Put an automatic in "low gear" (I still remember when it used to be called "grade retard" on some cars, which was to be used for braking only and not acceleration) and you'll get engine braking. and quicker « free » cabin heat in cold conditions. Engine braking won't heat the engine much over just idling, in fact it may even cool it off more because the governor will cut off fuel completely.

It’s a good question re:heat that seems to be unanswered. While it is compression and decompression, it’s not 100% efficient. And in a gas car, it’s releasing hot compressed air throughout the system, including the cat converter. I figured enough heat during compression would radiate to the engine. Plus more RPMs = more stuff warming up. I mean, the energy has to go somewhere, and the engine itself makes the most sen…

Normal engine braking (and even the compression-release "Jake brakes" on diesels, while more effective) doesn't develop anywhere near as much force as the wheel brakes. You're right that it does generate heat, but it's not a lot --- instead of purely compressing and releasing the compressed air, the engine is just acting as an air pump; the air gets compressed (and hotter) during the compression stroke, but instead of igniting, what would be the power stroke merely expands the air again to the same volume it had before, and then the exhaust stroke pushes it out with little restriction. I would bet that even if it's just idling, the heat of combustion will be far greater than whatever friction losses contribute to engine braking.

I'm getting ready to go full Battlestar Galactica in all of my appliances. It's now difficult to find high end washers and ovens without these features. At least right now we can choose not to connect the devices, but what happens if iot LTE connections get cheap enough that the choice is removed altogether, like with Tesla and other high end modern cars? I don't think I'm just being a Luddite. This really seems like…

How my devices configuration look (all their mac addresses banned on router level, they dont have access to internet):

- tv, not connected to network, using raspberry pi 4 for kodi, connecting outside trough squid proxy limiting domains it can connect to. Was never connected to internet

- roborock vacuum cleaner, rooted, software disabled, replaced by open source version

- android deviced moved to microg lineage, armored with xprivacy lua and netguard, by default on spoofing/blocking everything and disabled on case by case basis. If application demands private informations it doesnt have access to internet

- 100% self hosted, sftp for files, dns server, own mail server, squid proxy with custom scripts, blocking from domains to rewritting requests, customized searx, running on custom build freebsd

- browser on all devices, heavly armored firefox

- only linux and freebsd devices except android in phone (it is going to be replaced by linux/sailfish when released - cosmo communicator)

- each new device bought is evaluated before buy and returned after buying if it cant be rooted/blocked from internet.

- no device is bought with connectivity if not needed, following "no internet of shit principle"

There are lots of details around that, ask if interested.

Survailance capitalism? No thank you.

It’s hard to believe Samsung has any customers outside of their Korean hegemony. Samsung hasn’t proven themselves as a trustworthy smart electronics vendor in the past, be it smart TV, smart watch, or smart phone: 2015 - https://www.cnet.com/news/samsung-changes-smarttv-privacy-po... 2015 - https://arstechnica.com/information-technology/2015/06/new-e... 2015 - https://www.cnet.com/news/samsung-lg-smartwatches-yield-p…

I bought a $3000 top-end Samsung TV in 2015. The experience made it the last product from Samsung that I'll ever buy.

Their top of the line 4K HDR-UHD TV (for flat TVs, their highest was curved) was delivered with bright corners that were whitish all the time. Samsung claimed that this was within normal standards for a $3000 TV, and told me they would not repair it (after going around with them for a week or so). Luckily, the local retailer agreed to exchange it. Their denial of responsibility has cost them a lifetime of purchases.

We absolutely need consumer protection laws for this. The problem is that capitalism doesn't permit companies to simply succeed by being profitable. They must grow too. So the people who run the business are ultimately forced to squeeze every conceivable revenue stream from their products. The March towards forced online IoT and printer ink cartridge obsolescence models for everything is inevitable. Appliances used t…

Infinite expansion with finite resources. What could go wrong?

I can't agree more, but the choice in dumb TVs is limited. In the end the best option seems to be a video projector, but I really dislike the image quality v.s. a panel. Any recommendations?

You can try looking into commercial TVs (aka digital signage). These are displays with usually few smarts in them, and also designed to be on 24/7. You'll likely pay more than a regular consumer TV.

I tried this. At least for larger sizes, the price premium is often 2x and finding HDR - and sometimes even 4K - is hard: https://news.ycombinator.com/item?id=21664952

The post you're replying to suggests that an independent LTE connection will be bundled into every device, so that none of the interventions you've listed will work. Good luck maintaining your bubble.

I reckon that, given enough time, it’ll go the same was as everything else. Either you pay a subscription to remote it (and the inevitable ads that will appear), or you pay a premium for something without that functionality. I don’t see how this stops. Advertisers will stop at nothing to invade your life, and businesses are more than happy to facilitate them if they get some more money out of it.

Won't this create an opportunity for someone to enter the market with a TV that uses no ads or telemetry? Surely it is obvious there are millions of people who don't want smart TV's you would think a company offering a dumb TV would thrive. Are we just not at that point yet?

I guess part of the problem is brand recognition. 95% of a TV is the screen, and Samsung, LG, Sony and perhaps a couple of others own that market between them.

I see neither Samsung, LG, nor Sony getting on board, so you'd have to be buying their panels and do a good job with the electronics for people to but then.

That's fine in the ultra-premium space, the price to the consumer will cover the R&D, but mainstream, you'll just be Hannspree or something that has good panels but nobody knows our cares about you.

Maybe we should just ddos these endpoints, they don't deserve anything better.

Assuming the aren't well programmed, it might be preferable to spoof them with junk data.

Is anyone MITM-ing and publishing the data these devices are sending? It would be nice to reverse engineer and document their APIs. Somebody needs to be watching the watchers.

Why are people so worried about preserving the warranty on their electronics? If it lasted 30 days and you don’t break it while futzing with it, it’s likely to work through the warranty period anyway. If it doesn’t, buy another one. TVs are ridiculously inexpensive now. I see people online waiting years (perhaps 5% of their life) to mod their cars or electronics for fear of losing the warranty. Side note: Magnuson-Mo…

> If it doesn’t, buy another one. TVs are ridiculously inexpensive now. If you buy a mediocre one, sure? Good OLED TVs today still cost thousands. They are a big ticket purchase for most buyers. Hesitance in breaking them open is entirely sensible.

I'd say TVs, like mobile phones, are the sort of thing people spend beyond their means on, this makes it an even more expensive purchase, and a lot of people probably don't have the tools, the knowledge or the experience to crack open a flat panel TV without damaging it.

This is the point of “5G” everywhere. If the underlying phys and chips are cheap, low power and licensed appropriately a lot of “dumb” stuff will suddenly become smart whether you like it or not.
