Don't forget, food and shelter. Pretty sure that was free too

There's reasons behind this. LPDDR IIRC works most efficiently when it's closer to the CPU than what dimms would allow for.

Boosts speed and lowers the power requirements.

It also incentivizes people to buy larger SKUs than they originally wanted, which, bluntly, is probably the main driver for going that direction.... I'm just saying that there's technical reasons too

I'd say to try chromium, but you basically need to compile it yourself to get support for all the video codecs.

Yep. I work in IT support, almost entirely Windows but similar concepts apply.

I see people pushing 6G+ with the OS and remote desktop applications open sometimes. My current shop does almost everything by VDI/remote desktop.... So that's literally the only thing they need to load, it's just not good.

On the remote desktop side, we recently shifted from a balanced remote desktop server, over to a "memory optimised" VM, basically has more RAM but the same or similar CPU, because we kept running out of RAM for users, even though there was plenty of CPU available... It caused problems.

Memory is continually getting more important.

When I do the math on the bandwidth requirements to run everything, the next limit I think we're likely to hit is RAM access speed and bandwidth. We're just dealing with so much RAM at this point that the available bandwidth from the CPU to the RAM is less than the total memory allocation for the virtual system. Eg: 256G for the VM, and the CPU runs at, say, 288GB/s....

Luckily DDR 4/5 brings improvements here, though a lot of that stuff has yet to filter into datacenters

At most, they're very bad Faraday cages.

The vast majority of LTE bands are below 2600mhz, around 10 cm wavelength, which usually doesn't have any issue penetrating glass, and suffers very little degradation from the metal in the body of the car.

Aluminum materials, which are not uncommon for body panels, and other automotive components due to its light weight and relatively low cost, is non-ferrous and won't impact signal strength any more than glass will....

The Iron/steel in the vehicle, usually in the frame/engine, are the primary issues with regards to signal blocking. That's what microwaves make their Faraday cage from for good reason.

Many wireless providers also have sub 1ghz channels which are harder to block, they're generally slower for bandwidth, but that's another matter entirely.

Most of the dashboard is made of plastics and other non-ferrous materials, but it's littered with devices, supports, and wires that can impact signal integrity. These are usually fairly sparce and don't generate a lot of interference. Since the dashboard is directly adjacent to the windshield and driver/passenger windows, signal is more or less unimpeded in the desirable directions (horizontal, mainly). Unless you're putting your phone on the floor of your vehicle, you're generally okay for signal, as it passes through the majority of the dashboard, around components in the dashboard, and through the glass relatively unimpeded.

The exception to this is that some manufacturers seem to think it's a good idea to put materials in their safety glass that impede RF. God knows why. It might be a biproduct of a coating that is there for a different reason, but it's not great. That's when you need a fairly simple LTE repeater.

Which brings me to my point. You can forego the complex and unsupported LTE SIM over Bluetooth stuff by simply putting a relatively low power LTE repeater from a good signal location, such as the roof of the vehicle, to a bad signal location, such as the middle of the cabin it can literally be built into the overhead cabin light. Resolving the issues you've stated, without providing any data access to the vehicle itself. Such an add-on would be a small increase in cost, as such units can retail anywhere from a few hundred to thousands of dollars, but as that cost would replace the built in modem most people never wanted to begin with, the addition may actually make the whole car cheaper... With little more than Apple carplay/Android auto, to replace all the functionality they'll lose by removing the cars data connection.

It's a very silly and pointless argument overall, because vehicle manufacturers will not be removing the LTE modems from their vehicles, since that allows them to remotely gather your data, which they can sell. That increases profits and that's what they care about. So they're never going to listen to us regardless... As long as someone is buying their wiretap vehicles and basically handing them free money in the form of your personal data, they're going to keep doing it.

As a driver, all I really want is good music, good navigation, and easy access to all my controls.

I don't want to have to go into submenus to change my temp settings, or open the trunk.

IMO, a vehicle should be a fairly simple tool to operate. All of the nuances with driving should be how you use those controls to get to where you're going. Even with the (frankly, impressive) self driving tech we currently have, I still don't think it's ready to replace a driver at the wheel; bluntly, that's the only tech I really want in a car.

Automatic options for fairly standard functions, such as turning on your headlights at night, shutting off the highbeams when there's oncoming vehicles, and even automatic windshield wipers, can make things easier. Which I appreciate. I can override all of these systems, which is good. The advent of climate controls rather than "how hot" and "how cold" you want your blower to be and at what speed, is also nice. Even driving assist, like automatic lane keeping and adaptive cruise control is a nice-to-have. But these are all augmentations of systems and they're pretty transparent to the driver. If you don't want to use them, you can easily ignore or override the systems and do it yourself.

What I don't appreciate is all the infotainment garbage. I can literally play games on the touch screen of my partners 2019 accord. I tried it out and bluntly, it's not comfortable, it only works when the car isn't moving, and I'm not going to sit in my car to play games. That's dumb. I kind of get it for EVs for when they're charging, but honestly, I can have a better experience on my phone/tablet.

I don't need weather, I don't need a touch screen, and I don't need whatever garbage GPS system you were paid to sell with the car.

Give me Android auto/some carplay, with maybe FM as a backup in case of emergency, and I'm good. My phone already has data, my car doesn't need LTE. Give me buttons to press for all climate and driving functions and I'm a happy person.

I don't want to navigate some menu to try to turn on my defogger. Fuck off.

Driving tech should be transparent to anyone who doesn't give a shit, and just wants to drive down the road.

Let's just feed them to the plants by burying them alive.

This is less than interesting.

ISPs don't want to cut off their income here. I'm certain they have a very good idea of how many of their customers, especially those paying for higher tier plans, are either getting constant DMCA requests, or have a persistent connection to a VPN service. They have a good idea of how much money they're making from people pirating content, so this position for them is hardly surprising.

At the same time, I'd rather they fight with the copyright trolls than me. Regardless of the reason for why they're doing it, it's a good thing to fight for.

IMO, they shouldn't be responsible for this because they're not tasked with enforcing laws. They must abide by them, and they have a legal, or at least, moral obligation to report any felonies/crimes that they're aware of (with varying degrees of obligation depending on the severity of the crime. Eg, I'm less bothered if they don't report, say, piracy, than I would be if they don't report CP/murder/violent crimes, etc).

If the LEO's want a service cut off for a good reason, then let them get a court order for it. They should not be obligated by law to enforce such laws. Any enforcement should be handled by an independent organization, and be filtered through the court system as a check/balance for the whole cabal. They shouldn't be forced to both find and enforce infractions. Reporting suspected infractions, maybe. Forwarding legal requests to customers, sure (like DMCA notices). Oblige disconnect requests from law enforcement by request (when confirmed necessary by courts in the presence of reasonable evidence), absolutely.

But having the ISPs do all that themselves with little oversight, is both a danger to their clients, to their liability, and to the public at large, mainly in the context of free speech. The ISP is just the middle man, the messenger. They don't host the content, nor should they police it, or the access you can get to it. I'm all for collaboration in the interest of enforcing the law, but putting the entire obligation on the ISP seems foolish to me.

Cyber crimes is one area of law enforcement that I don't think should be defunded. It may be that ACAB, but those doing the investigative work, away from public interaction (and possible abuse), are not the root of the problem there.

I dunno, just my opinion man.

This has been happening for a lot longer than just Windows 11.

Several people I've spoken to, who have purchased OEM computers from the likes of Dell, HP, Lenovo and others, did not know that bitlocker FDE was enabled, and they were not aware that they needed to back up their recovery key.

On at least one occasion, this caused someone to lose the contents of their laptop when Windows failed to finish booting into the OS. The drive was fine as far as I could tell, but the content on the drive would not complete the boot up sequence and would bsod/boot loop the system, so data retrieval was not possible without the recovery key, which they did not have. That was a Windows 10 Dell system from 2020 or so.

My opinion is that FDE is a good thing.

My advice is if you have FDE enabled, backup your recovery keys. It's easy, but it won't directly save to a file on the filesystem that's locked by the key to which the recovery key applies. The easiest workaround is to "print" it, then use the built in Microsoft print to PDF, then dump it wherever you want. Afterwards, put it somewhere safe. Doesn't matter where, but anywhere that isn't the encrypted drive. Maybe Google drive, maybe a USB flash drive, maybe email it to yourself. I dunno, just somewhere you can retrieve if that system isn't working.

When you're done doing that, go check the same on your parents computers, friends, brothers and sisters..... If they're someone you care about, and they have a windows computer, check. Get those recovery keys backed up somewhere.

I'm just happy that Lemmy.ca made the list.

If it's from Ikea, I can probably fit an entire bedroom worth of furniture into my two door Honda civic.

Everything they make is flat packed, and you have to assemble it into it's 3D form after purchase.

I can stack so many of those Ikea items in my tiny shitbox.
