I've been daily driving Linux for maybe 10 years, and I see all these pushes for "lets make it easy. no cli!" as counter-productive. The cli is the interface on unix based systems, and the more time you spend learning fundame

I can only assume the Google example would be part of a script/cli program that is meant to crash with an error on a bad parameter or similar. Perhaps the point is to catch the exception for control flow? My personal goal is to get thi

Did we not all evangelize Google in it's early days? Also, none of these accounts saying nice things appear to be bots or kagi-focused in any way, so I think it's safe to assume they do actually just like it.

Funny, the original commit message for that suggests it was simply a precaution. It's not out of the ordinary to avoid newer kernel features just in case. > This is a short-term patch. Unprivileged use of CLONE_NEWUSER is certainly

Exactly, "set up". Many people (not all) don't want to fiddle with things, they just want it to work out of the box. The importance of secure defaults can't be overstated, especially when there are virtually no downsides

As I mentioned in another comment, the linux kernel feature (user namespaces) that enables "rootless" containers was released in February 2013, and Docker was released soon after in March of that year. For whatever reason, they ha

Unikernels aren't too complicated conceptually. They're more or less a kernel stripped down to the bare minimum required by a single application. The complete bundle of the minimal kernel and application together is called a unike

No mention of user namespaces whatsoever, which is the primary security isolation mechanism for containers on linux. This is what enables "rootless" mode. Of course, this is from 2017, but user namespaces were released with linux

Is it? Is there no reasonable case where you have a subsystem in a game crash, then restart itself? Unless I'm mistaken, I've experienced this myself in video games more than once. Anything beats a full crash with a pointless erro

It's nice to know that. Could not tell that easily by reading the entire readme or the linked docs. If founders/devs are reading this, it'd probably be a good idea to make it obvious what this is for up front. Even just a one
