"Discovered a very interesting thing about DeepSeek-R1 and all reasoning models: The wrong answers are much longer while the correct answers are much shorter."
For Windows, IE11/Trident. This may sound ridiculous, but if you think about it, it's still maintained security-wise (and will be forever, as per MS), and since its codebase has been frozen a few years ago, its attack surface can only shrink with time.
So if you're OK with the limited compatibility, it might be worth considering.
Dead is not quite correct. IE has been put on a permanent feature freeze, but MS has committed to keep releasing security updates for IE11 during Windows 10's entire lifetime. It is also the only browser shipping with the current Server editions. So I would argue that immortal would be a more accurate term.
If you trust the signed source code there's no reason you shouldn't trust the signed binary - unless you have sufficient time and expertise to audit the source.
