<p>Other comments also hint at this idea, a distributed training solution is currently an open research problem. Solving it is not easy, yet. But 10 years ago what we have today for LLMs would have looked similarly impossible, so have hope, and apply yourself to the problem if you find it interesting!</p>

<p>In states in the USA which perform emissions testing, many of them did not mandate it for diesel cars.  For example, I owned a VW Jetta TDI and in New York (which has yearly emissions testing where an OBDII computer is mandated to be connected to gasoline powered cars in order to pass the yearly emissions inspection) and I was exempt from the emissions testing entirely.<p>A 3rd party sensor would be incredibly expensive for inspection stations to purchase as it would need to meter the air and fuel which enter the engine (assuming we aren't going to trust the car's computer which already knows these figures) as well as to measure the emissions out of the tail pipe.  This is economically unrealistic to implement without a dramatic price increase in the cost of regular emissions testing.<p>Trusting the computer is the economical and realistically widely implementable solution.  But yes, it has it's blind spots.</p>

<p>So the natural extension of this would be plugins which have curated open source allow-lists?  Similar to how I trust uBlock Origin's default ad filtering block-lists, I would similarly trust a curated open source allow-list for email domains, and then I would add my own from the "to screen" folder?</p>

<p>No shoving sensors required, the data is all in the ECU accessible over OBDII interface.  The car knows if it’s compliant in real time using the sensors it already has.</p>

<p>It was. We had sealed beam headlights for a while till we didn’t.  There were common rules for aiming and it worked. The lights weren’t all that bright and the styling was not stellar, however.</p>

<p>Qualcomm is a “fool me once, shame on you, fool me twice, you don’t fool me twice” kind of situation. So many horrible experiences in the past that people are going to be hesitant.<p>Qualcomm are trying harder now it seems. But it will take time to repair their reputation in the PC market.</p>

<p>Xerox had (maybe still has?) some printers with 5 or 6 color toner capacity. CMYK plus you could order special color toner in stock or fully custom mixes (minimum order sizes apply for full custom) but it was great for companies who had logos which could not be exactly represented by CMYK half toning as the spot color toner could be their exact logo color.<p>I’m sure the same kind of thing would be possible using Prusa’s documented methods with a little extra work.</p>

<p>Q8 quant is very minimal fall off in terms of KLD against the lab 16 bit. If you have the memory for BF16 KV-cache (which is usually easier to stomach) then the Q8 is very close. But even Q8 quant model with Q8 KV-cache is very close.<p>Smaller quants for the model start to fall off but more importantly, smaller KV-cache quants fall off much faster so avoid less than Q8 there.</p>

<p>Normal secure boot does not use the TPM.  Secure boot is the proactive process of ensuring only allowed code loads and executes.<p>The TPM is used for measured boot, the post process to understand what actually was booted and if the right set of things were booted then to allow unlocking of specific items like keys.<p>Both are important but they are not the same thing.</p>

<p>The article you link to explains how to defeat the sniffing with TPM 2.0. But also, there’s no reason a physical TPM has to be a separate IC package.</p>

<p>Would love to see actual security focused hardware/software features, like full OP-TEE, fTPM (or a more ideally a real physical TPM), and similar.  For example, so that the OTP isn't the only way to store a disk encryption unlock key.<p>The existing secure boot mechanisms aren't bad, but allowing for more than one public key hash in OTP would be nice, too.<p>These kinds of things are expected to be on modern embedded SOCs and SOMs now.</p>

<p>It's a pretty normal thing to do for small LCD screens.  Linux has had SPI framebuffer support via fbtft subsystem (in staging tree now, previously was out of tree) for well over a decade.  It works quite well.</p>

<p>Many silicon vendors, when providing said binary blobs to a device OEM or even just documentation or source code for the binary blobs, will make companies agree to a license or other legal terms which prohibits reverse engineering.  Often the direct recipient of the binary blobs (the OEM of the device) cannot legally let their employees nor contractors perform the reverse engineering.<p>Generally, unless a similar license or legal terms are required to be agreed to by the end user, nothing stops the end user from reversing said binary blobs.  But before you attempt this, be sure you fully understand every legal document which was presented to you by the device vendor.  Click-through EULAs included.</p>

<p>There’s lies, damn lies, and lies that disks tell the operating system. Don’t believe any of them!<p>If you need to know it’s been persisted to non-volatile storage then you need to own the full stack of every piece of software between the OS and the actual physical memory.<p>Every managed flash drive is going to have layers and layers of complexity and caching and things you simply can’t easily control or really understand. Don’t trust it unless you know exactly how it works all the way down.</p>

<p>I give you $100 cash and you give me $100 worth of stock in return.  Now you give me $100 cash to buy something from me that cost me $80 to produce.  I end up with $100 worth of stock in your company which cost me only $80.  No?<p>NVIDIA gross margins lately are like 75%, so it's more like you give me $100 to buy something from me that cost me $25 to produce, hence I end up with $100 worth of stock in your company and it only cost me $25.</p>
