How do you know that the values of the automatically generated dashboards are correct?

This has nothing to do with nuclear weapons. The only problem here is that iran has petrol. Thats it.

AWS EC2 does not migrate between hosts - They want you to pay more for redundancy, and they encourage you to use all the tools (paying for every single byte processed or transferred, of course). And if it is goes down, it is because you didn't follow AWS best practices (= paying even more)

Not all australia is moving g at the same speed. Check south Australia, and it is a massive success. The difference is that the government invested in renewewals, along with solar in rooftops. As SA is smaller they did not had pressure from lobbies. Now, are almost 100% renewal energy all year long.

It can be done.

Amazon was an innovative, day 1 company, but it is not any more. They are becoming an IBM.

Enshitification is here: they are doing mass layoffs periodically, and you don't hear innovative news from AWS any more.

Additionally, companies are realising that they are pretty much using a minor offering of the AWS products, competitors are catching up, and every day there are lessser reasons to pay the AWS premium.

I have created an internal tool for my company. They are plugins that are installed in the browsers for the computers owned by the business, and reports the domain when you open a new browser or tab with a url that you did not manually typed. If blacklisted, it completely blocks the browser. If it is the first time we see the domain, we display a pop up “think before you act” and the it department will dive deep to whitelist it.

The first week there is a bit of noise while we whitelisted the common domains used by the users. After that it really puts you back on alert when you clicked on a email that takes you to new domains - that could be used for phishing.

Thanks for sharing. It is impressive to see how fine tuning makes such a huge difference. It is a matter of cost to decide whether you use a large llm or fine tune a small one.

As a noob in fine tuning, question: how did you decided the values of the hyper parameters ?
