what are your favourite commands to run over ssh (like `ssh user@host "COMMAND"`)? the only thing I have in my history right now is: ssh user@host 'tcpdump -i any BPF_FILTER_GOES_HERE -w -' > out.pcap to quickly get a local pcap file
tcpdump commands filter

New week new demo! Today I want to showcase the CLI to control the @superlogical multiplexer. The CLI is an extremely powerful tool for automation and hooking into other tools like editors, agentic coding tools, and more. And, it's super fun! Everything you can do in the GUI, you can do via the CLI. Actually, you can do more in the CLI. You can create sessions, run commands, make splits, move things around, change focus, simulate any input device (key/mouse/etc.), wait on scripts, and more. There are a couple unique parts of Rex I'm showing off here too: our streaming event system that any cl… Related

Even if an AI did exactly what I told it to do, precisely and without error, I would still work hard as an engineer. Brooks told us why in 1986: "Even perfect program verification can only establish that a program meets its specification. Much of the essence of building a program is in fact the debugging of the specification." What he meant is that engineering is not the execution of commands... It is very much design. And design is ridiculously difficult. You need to decide what you will build and how you will build it. Of course, you can outsource the design to the AI. But that's assuming t… Related

lazyweb: I'm curious about how to get a list of all of the different "kinds" of things SSH can do. my impression is that there's: - open a terminal session - just run one command - TCP port forwarding - X11 forwarding - copy files and that these all separate "commands" or "protocols" inside SSH. Not sure how to get a list of all of them though. edit: I think the answer is "read https://github.com/openssh/openssh-portable/blob/master/PROTOCOL and https://www.rfc-editor.org/rfc/rfc4254.txt" Related

After a civil engineering prof mention that the people in their department who work on water quality/treatment tend to drink out of the water cooler and not drink tap water, I tried getting a water filtration system. "Everyone" says Vancouver has really good water, so I didn't expect much, but the system's pre-filter catches a lot of green flecks (copper). The RDA of copper is < 1mg, which is on the order of these flecks, so it seems like I was ingesting many times the RDA in copper daily. Related

MCP
Their words
I think the main beauty is, is that models are really good at calling Unix commands. So if you just add another CLI, that's just another Unix command in the end. And MCP is… That has to be added in training. That's not a very natural thing for the model. It requires a very specific syntax. And the biggest thing, it's not composable.

That is absolutely possible. I’m actually putting less credence on that one just because you need to happen every single time.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public

especially about tone.
Only the post's own words are translated. A quoted post, a linked
