If you are serious about working in a terminal, then I highly recommend learning modern replacements for the old tools.
In this case ripgrep (or rg) https://github.com/BurntSushi/ripgrep is phenomenal. Especially for searching recursively in a large directory tree it is unbelievably quicker than regular grep.
It won't be installed on any random machine, so grep is still useful, but if you regularly need to text search in files then there are better tools.
The fact that Kbin is handling the wave worse than Lemmy is not unrelated to the fact that Lemmy's tech stack is much lighter weight and more efficient. It is a fundamental issue with the technology. If either are going to become major players then they need exponential growth, and Lemmy is just better at that.
A lot of people seem to be talking about whether PHP has enough developer support, but that isn't the main issue.
The issue is that code written in PHP is probably at least 10 times less efficient in terms of CPU and memory than the equivalent code written in Rust.
This means that loads of hobbyist developers will be able to run lemmy instances for a fraction of the ongoing cost of kbin.
Smoked salmon looks "raw" largely because it is raw. It has never been heated.
Smoking the fish does indeed give a very different flavour to non-smoked fillet. That shouldn't be any great surprise.
Why is it safe? Well good quality raw salmon is also safe (see sushi). But the smoking does have an effect of preserving the fish and making it less of an environment where bacteria would thrive.
