   Hmmm, you made me think and try to recollect. And to my surprise, I can't really remember the fact of The Presentation being an influence. But I am quite sure it must have been , I can see no other option. Hm, memory is a tricky thi

   I couldn't find a good readline library in pure Go, that would also interact well with the tcell package I am using for the TUI. This annoyed me really hard, but eventually I said, screw that, and went with the minimum I had to write t

   :) I've seen somebody mention the idea of applying this to a shell, but only after pressing some special key (e.g. Ctrl-Enter). Would probably make it un-dangerous enough? This seems to be what people want of up too, anyway. As to th

   How can I do the "drop user permissions" thing? I haven't seen such a keyword mentioned by anyone yet, sounds interesting. Does this not require some kind of syscall, however, thus not really being cross-platform anyway?

   Hmm, interesting thought! The tool needs to do some ugly buffering however; would there be place for it in a shell? Also, I suppose some kind of "Ctrl-Enter" or something would be a better idea instead? So that it could also be h

   I don't think LD_PRELOAD would be enough; there are programs which don't use libc and reach straight for syscalls (e.g. the whole Go ecosystem/runtime)

   That's totally where my long-term vision goes! :D But I'm very unsure if I'll have enough time and resources to be able to reach it :/ My strong hope is however that the Luna language[1] & team may get us there faste

   Thanks for the ideas, and for the good words! :) Do you know of any nice screencast/video where some similar functionality of helm would be shown? Does it also work for shell commands in some way? I'm not an emacs user...

    Can you please elaborate a bit on the textmate approach? I don't fully grasp it from this description yet... while it totally sounds interesting...

    Sounds interesting; but is there any way I could change to a different user if not running as root?... also, even if yes, how do I dynamically create a non-privileged user, or find a pre-existing one?

    Is it possible to do system call redirection??

    Is it possible to configure namespaces so that they allow read-only access?

    I'm ok with focusing on Linux as the prime target for up . Though I'm totally trying to think about cross-platform approaches too, obviously.

    I don't see how linting could work, I'm afraid. There are obscure options in zip, git, grep, and what else, not to mention full-blown interpreters like awk and perl, that can edit files via a myriad of syntaxes, and then there&#x2

    Hmmm; so what would you think of the other popular suggestion, to add a (probably default) mode, where only after pressing, say, Ctrl-Enter, the command would be executed? With another shortcut allowing to switch back and forth to the &quot

    Thanks a lot for the link! I'll totally try to look into this. If it really proves to be as easy as a single syscall... Oh, wow, now that'd be a killer...

    Wow, firejail seems super interesting, thanks a lot for the idea and mention! I'm not sure if I'll manage to use it, but certainly a good direction for some further research! https://firejail.wordpress.com/

    Maybe cutting off network access could be done too? That would reduce some potentially useful features, but it could be a parameter to enable it (hey, we're talking Linux, never enough parameters! ;). That is, assuming that a syscalls&

    Can you elaborate a bit more? Which functionality are you referring to? And why did you disable it? Really curious! (Author of up here) I get it that by eshell you mean a shell in Emacs? (That's at least what I'm getting as a fi

    Hm. I think in my ideal vision, you'd then quit up , and somehow magically have the pipeline ready at your fingertips on the shell prompt, so that you can just add the `-delete` there in a "regular" fashion, and press Enter.

    Author here: I hope something like that (syscall/capabilities limits) could work. If it is possible, it would just mostly solve the problem, I believe. I'm kinda starting to realize, that probably any command modifying some extern

    That's the main direction I currently seem to be coalescing on based on feedback I'm getting. That said, one person on lobste.rs suggested trying to play with Linux capabilities, to make the filesystem immutable... now that woul

    Thanks! :) See also my "prior art" note in the readme ;) I also had the "why didn't somebody think of this already" moment when I thought of it ;) And somebody in fact more or less did, just I wasn't able f

    Right, it's theoretically dangerous, or I'd say practically: "please think when using it"... though I personally couldn't find any other serious problematic example other than typing something clearly dangerous in t

    Your responses give me the most interesting glimpse behind the curtain on how's the real life working in China I've ever had; super interesting, thanks a lot for this! :) I'll have to try to ask my parents in what ways it was

    Cool, so seems not worse than a CGA at 320x200, if that shows up to be true! :) That's something I'm totally looking forward to hopefully be able to use at some point in future. Will probably take some time however till it trickle
