Turbos don't inject exhaust air into an intake. Exhaust air spins the hot side of the turbo which causes the cool side to also spin. The cool side sucks in fresh air. Not exhaust air.
Your comment would make more sense if you mentioned exhaust gas recirculation (EGR) system.
I already had 2x 5070's that I had purchased a year or more ago, so getting an additional two to fill up the PCIe slots on the motherboard seemed reasonable.
I did some math/shopping as well. To get 48GB of VRAM you can get 2x 3090s but that is $3k. A single 5090 is $4k but has 32GB, great for running models like Qwen 27B but maybe nothing else depending on your model settings. Already having 2x 5070, where each card is around $600, it made sense for me to get two more which was $1200 and the memory speeds aligned.
The best value option if you're building from scratch is go with 5060 ti (16GB VRAM). Each of those cards are $570/each on Amazon, cheaper than 4x 5070's. Only downside is memory speed is slightly slower, but you wind up with 64GB of VRAM and you can run big models and small models alongside each other comfortably.
In my setup I ran Qwen3.5 9B for fast inference on simple things and Qwen3.6 27B Q6 for coding work. But I ran into stability issues, so I use llama-swap to dynamically swap models. But with 64GB of VRAM, you wouldn't have that issue. There is overhead to loading LLMs into VRAM that isn't clear, so having extra VRAM is a helpful buffer.
> from my experience if you give the models a way to self-verify correctness they succeed basically 100% of the time
My experience is that if you can get the model to one shot the task, you'll do fine but if it has to iterate it leaves things worse than before and almost always requires human intervention after burning through an enormous amount of tokens
This was stated about the key: "Folded into the base is a mechanical backup key, a flat metal blade in a hinged housing."
I own a BYD: this is not true. The key is not hinged; rather, the entire mechanical key pulls out when a small clip is unlatched near the top of the assembly (you can see it in the CT). I assume the circular hinge-looking mechanism in the CT is just a by product of the plastic/metal weld process.
I wasn’t surprised by the backup key, but rather by how empty it was. I really wish key fobs were smaller. They are quite bulky in a pocket and bigger than all my actual keys combined.
Now that’s an idea… I found one for my car, but kind of hate it.
I don’t have a 3D printer currently. I did help my cousin’s kid by one and they told me if I ever wanted to print something to let them know, but I have a feeling I’ll need to design my own with some trial and error.
I’ve hesitated buying one, because the idea of having a machine to melt plastic in my house seems like a bad idea when it comes to air quality.
Depends on the plastic, but even the most benign ones put out very minor amounts of fumes if YouTube testers are to be believed. Note that fumes in this case just means that they are seeing changes in AQI meters, which is something that can happen with too many people sitting in a room.
If it’s something you worry about, the enclosed models frequently either come with, or can be fitted with a carbon filter, and if you are really worried, you can use dryer vent to get it outside.
With the most popular plastic (PLA) at printing temperatures, there isn’t any data showing toxic byproducts. When you get into things like ABS and resin you have to think more about fumes.
Do not print a key fob out of PLA. It will not survive summer car temperatures. A better choice is PETG, or ABS and ASA if you have an enclosed printer that can vent outside.
I'm guessing parent-poster is saying the "is" should be "are", on the basis that the word "components" is plural.
That said, I didn't perceive a problem either, and my self-diagnosis is that "none of the X" feels like it could be evoking a singular item that failed to be found.
Yep, I think the singular is ok, as it could be just one. Seems like it could be both.
Cambridge says...
> In formal styles, we use none of with a singular verb when it is the subject. However, in informal speaking, people often use plural verbs...
Collins says:
> Since none has the meanings “not one” and “not any,” some insist that it always be treated as a singular and be followed by a singular verb: The rescue party searched for survivors, but none was found. However, none has been used with both singular and plural verbs since the 9th century. When the sense is “not any persons or things” (as in the example above), the plural is more common: … none were found. Only when none is clearly intended to mean “not one” or “not any” is it followed by a singular verb: Of all my articles, none has received more acclaim than my latest one.
But it was "none of -these- X" which (to me, at least) is a secondary signal for plurality indicating that "are" is (doubly) preferable to "is".
(I don't find "none of these components is ..." to be egregiously wrong but it definitely gives a brain hiccup where the "... are ..." variant is much smoother.)
I guess my intent was not to point out that it has a mechanical key, rather that the description of the key on the webpage was wrong (it is not hinged).
The mechanical key fallback pattern is standard across the industry for sure.
Article says key fobs are the same across all their cars and this looks the same as mine for a Sealion 5, there is no hinge for the key you just pull it out.
Likely the article authors just assumed from looking at the scan, if they’d actually tried to remove the key they would have realised their mistake.
Before keyless became defacto standard, most keys were fixed on a hinge - you'd first unlock your car by pressing a button on the fob, then swing the key open and use it to start the car.
Nowadays the physical key is only a backup, safely stowed inside the fob. It is meant to be pulled out only in an emergency.
Mercedes changed to the IR key in maybe turn of the 90's. The plastic blob would be used to turn the ignition like before, but the locking part was electrical (optical). There was still a metal key that could be pulled out and used on the exterior locks if the central locking was out.
When keyless start came, there was a dummy button that fit in the ignition lock that could be pushed to start. If there was a problem, you could pop it out and use the key as before.
IIRC, all that, so may have mistakes. Just crossed my mind that they went a few decades between no metal ignition key and keyless. MB being MB, I wouldn't be surprised if they still had models with that same "old" system and keyless as an option.
Yes sadly the Hyundai and Kia key fobs of EVs (at least EV9) don’t have the mechanical backup key in the fob anymore. So you need to carry it on your keychain. Don’t leave it in your trunk. If the 12V battery does out you won’t be able to get into the car.
Anecdotally on my Hyundai ionic hybrid from 2018 it does have a mechanical key in the fob, but it is very non-obvious. It’s physically the same piece as the keyring section at the top of the fob. There is a small catch you release to remove the key from the plastic fob body and it slides out the top.
All this to say Hyundai certainly knows how to do this. If they didn’t do it, it is almost certainly a deliberate omission.
I think the staunch "no screen" mentality is a broad-stroke lever that non-technical thought leaders in the child wellness space have stuck to, and I understand where they come from.
Though, as someone who owes his livelihood to being able to tinker and experiment with technology as a child, I'm looking toward a more measured approach. I may very well set up an airgapped Linux box (Windows has come a long way since the XP days, and gone entirely the wrong way) and let my kids proverbially "have at it" - this way, they can't get stuck in big tech's psycho-loops or sucked into YouTube's colourful dopamine machine - which I think, is the entire drive behind "no screens".
We set up a “kid laptop” for our kids (ages 3, 6 and 9) that has a short list of allowed websites and a curated set of installed programs.
We treat it like any other toy: they can pretty much play with it whenever they want for as long as they want. Of course they have to share it between the three of them, so there’s a natural limit there.
Every so often we’ll add something new; most recently I installed SimAnt after we were watching ants in our backyard.
