It's the method they used to create the proof that's in question here. They claim their amazing product did it, and therefore you should buy their product because will do amazing things for you too!

Yes, I understand all that. The original author points out that completely ditching sha-1 will be a huge pain, very costly, and won't meaningfully improve security. You responded by saying we aren't completely ditching sha-1, which seems to lend credence to the argument that sha-1 is still safe enough to use. That's where I'm confused. Having two hashes for each object in a git repo, a sha-1 and a sha256, is not the same as wholesale deleting your rsa-1024 keys and replacing them with rsa-2048. If I'm only looking at the sha-1 and all my tools only look at that, then the sha256 isn't helping me. Is it?

If we are changing to sha256 because sha-1 is broken, how can we trust all those mappings and signatures?? This makes it even more confusing as to why this change is being made

A proprietary LLM developed to run these proprietary tools might just maybe have guards in place to prevent it from telling you any details about what it's doing, lest you learn enough to not need that LLM

You are absolutely correct. The whole reason LLMs kinda suck at chip design (compared to say, writing react apps) is because chip designers are and have always been hyper paranoid about protecting their designs. The tools from Synopsis and the like are also very heavily protected. Nobody even feels safe discussing tips and tricks or problems and solutions for using the tools in public forums, we're all pretty sure that's forbidden in the software license agreements.

We don't even have any cloud solutions for chip design because of this paranoia. Nobody trusts anyone else with their chip designs. Instead we all build private compute farms to run our simulation and synthesis jobs. Every new company that wants to build chips has to reimplement the infrastructure to do it from scratch. It's kind of ridiculous.

So they are working with OpenAI to create an LLM that is trained on how to "expertly" use Synopsis tools. This is:

- Synopsis admitting that their tools are very difficult to use (not a flex)

- Synopsis doubling down on keeping their tools as expensive and proprietary as possible (not letting all LLMs train to use their tools, just this GPT-Synopsis LLM)

- OpenAI announcing a new (very not open) business model where you can pay them to create an exclusive proprietary LLM that can help people use your crappy product

Just amazing :-|

UPDATE: just realized that this LLM can also suggest that you buy more licenses of Synopsis tools since that will be the limiting factor to your productivity once this LLM makes everything else better. Yay.

If we don't need to migrate repos to sha256 them why do we need to change git to use sha256?

The wording, "Where does the money go," strongly suggests a fix supply of money, which not true.

LVT is just another form of attempted centralized control of the market and it will be just as susceptible to government corruption, cronyism, lobbying, etc.

Is this the same project, or a different project that does the same thing. I took a quick glance at both and the descriptions are very similar

The idea here is you get to work, but you don't have to work.

You should certainly try to do the least amount of harm possible. We don't really understand what harm is in all cases. We don't fully understand the lived experience of a chicken or the lettuce plant we cut up or the rabbit that died because we ate his lettuce. You could really tie yourself in knots trying to figure out what is less harmful overall.

I'm not even sure what your point is anymore. If Google decides they don't want you to log in anymore, you can't log in anymore. It doesn't matter if you try to log in with a passkey, a password, your fingerprint, or sending a secret code in with carrier pidgeon. This has nothing to do with passkeys vs passwords vs anything else.

If Google does want you to be able to log in then they will work with you to make that happen, whether you forgot your password, lost your passkey, or your carrier pidgeon died.

Passkeys are not special in this regard at all. What does make them special is that nobody can use a phishing attack to steal your passkey and log in to your account. Nobody can guess your passkey and log into your account. Nobody can intercept your passkey in flight and log in as you. That's the important distinction.

Do you understand that this is a classic manipulation tactic? Say the false/provocative/attention grabbing thing loudly then retract/explain/apologize later for it quietly.

B12 is generally the biggest concern. Vegans need to take vitamin supplements to get it. The B12 in those supplements is produced in factories doing bacterial fermentation

True herbivores have stomachs that can ferment B12 from the plants they eat. We do not

No it's not. Google flips a bit in their database and no matter what kind of authentication you set up with them, you get denied

I won't because it's all so opaque and proprietary and driven by an insane need for OpenAI and Anthropic to provide a return on MASSIVE investment. There is absolutely some smoke and mirrors involved. How much? We don't know. But it sure is exciting to imagine their product is now smarter than humans and they are totally benevolent corporations. I want that to be true as much as anyone, but I have lived too long on this earth to believe it wholeheartedly
