one thing that kind of bothers me about this post is that it feels like on some level I "should" be explaining what a login shell is (to explain the diff between .bashrc and .bash_profile) jvns.ca/blog/2025/02/13/how-to…
but if I try it always feels like it descends into drawing some kind of diagram like this and it just doesn't feel worth it, like who has time for that (source: blog.flowblok.id.au/2013-02/sh…)
I think a big part of the problem is that interactive login/non-login shells are a distinction that evolved very early in the history of Unix and the thing it was meant to deal with is almost entirely irrelevant anymore.
brain dump follows: you probably know at least some of this already but i don't think i can make it make sense to people who don't know chunks of it without laying out the whole thing.
back in the 1980s, you'd be working at a text mode terminal - the Linux "text console" login prompt is held over from those days, it looks almost exactly like what you'd have seen - and after you logged in, you were immediately interacting with your shell; no layers in between.
now suppose, at this terminal, you're editing a file in vi and you want to get back to the shell for a minute
there's no ctrl-alt-Fn to get another "virtual console", and there's no ctrl-Z to suspend the running program and go back to the shell. and `screen`-like programs haven't been invented yet.
but what *has* been invented is the vi/ex `:sh` command, which causes vi to start a _nested_ interactive shell and wait for you to exit that shell. when you do, you go back to editing your file. most full-screen interactive programs from that era (e.g. pine, trn) have a similar command.
the login/non-login distinction was originally meant to distinguish the outermost shell from nested shells, because some shell setup (like setting $PATH) only needs to be done in the outermost shell and will automatically inherit to all nested shells, versus other setup things (like setting your prompt) don't inherit and need to be done again for the nested shells
this distinction no longer works as intended because of GUIs - whether logging into a window system runs any shell startup files at all, depends on which window system it is and how it's configured; whether the shell running in a terminal window is a login shell or not depends on the terminal-window program and how *that* is configured; similarly for shells running inside screen-like programs. it's a big mess.
and it's also not really important anymore because control-Z/fg/bg and the ability to have multiple terminal windows / virtual consoles / screen panes open at once have pretty much completely superseded the use of nested shells.
as early as 1995 I remember reading guides that said effectively "the login/non-login distinction is no longer useful. make your .bash_profile just say `source ~/.bashrc` and nothing else, put all your configuration in .bashrc, and forget about it."
(interactive/non-interactive is another whole post and is, unfortunately, still quite relevant)
Wrote up my first impressions of the new GPT-4.5 - it's quite slow, VERY expensive and doesn't appear to be a notable leap forward from GPT-4o or o3-mini simonwillison.net/2025/Feb/27/…

This unified meetings app is a cool idea. You basically use it to store your meeting links, so you don't have to scroll your email for it. If you have a lot of meetings you will probably find this useful. apps.apple.com/us/app/perspect…
Tired of searching through emails, calendars, and messages to find the right meeting link? Perspective Meetings makes it easy to keep all your video meeting links in one convenient place.
@cachondo I guess, but I find the idea useful for recurring things at least. I don't use calendaring in my life already, and I tried using reminders but I find it's reminding lacking so maybe that's why I like this idea.
I'd be lost without a calendar. I have a work one, we have a family one, things just all tie together. You can tap any date or time in iOS from an email or sms and, boom. it's stored. We can ask our smart speakers for a rundown or move things. it's just ... one of those incredibly useful things.
@kevinrj @cachondo One of the main reasons I switched everything to Google it so I don’t miss important things now that my schedule will have more than one recurring meeting lol

Listen, it feels impossible that these MAGA assholes would ever change their minds, and yeah some never will...
BUT
I was a Republican asshole once, so was my brother, so was my husband, so were many of my friends. In fact, judging from the people I've met here, many of you grew up in oppressive Conservative/Religious environments, but you changed too. It is possible, we have a fight coming up, and we are going to need as many people as we can get.
Learning how to talk to each other is going to be important.
I know it's hard to find stuff to hold onto right now, but the fact that Mastodon exists gives me hope. There's millions of people here, that want the world to be a fair and equitable place.

The House GOP just passed a draconian budget resolution by the slimmest of margins, and if you’ve seen Republican misinformation since the vote, you might think it’s already law.

Despite having to focus on completely transforming the way we do deception & detection (including rewriting over a thousand rules into Suricata), our research team cranked out MORE 🏷️ than EVER! 💪 2/6
The enhancements we made to our Global Observation Grid gave us *unprecedented* visibility into attacker activity, and we now collect orders of magnitude more malicious and suspicious source IPs than ever before. 3/6
That activity gave us increased insight into the most prolific vulns being exploited, w/far more malicious sources being identified daily. We've also reduced the ⏱️ to threat intel value to minutes vs ~hour (so high-fidelity blocklists provide nigh instant coverage if SOC teams use them). 4/6
And, sadly, if you ignore old vulns, you're all kinds of borked. Many vulns we see exploited daily are older than graduates of infosec degrees from the past few years, 5/6

At @couchdb we take data safety extreeeeemly serious.
A few weeks ago, we had to make sure we were not susceptible to a particularly gnarly race condition that could lead to catastrophic data loss.
We were not (😮💨), but to make sure we had to go back to the very foundations any database is built on: basic syscalls, a filesystem, process crashes and (lying) storage devices.

This is insane to me. I'm biased, though. Punctuation and spelling matter inherantly to me, but I also need them to be correct so speech can give me the best version of a message. I can also add punctuation more easily thanks to braille screen input, and can hear spelling mistakes I make more easily thanks to speech feedback. I'll continue writing the most grammatically correct posts and texts I can, even if doing so is lame.
