Hovering over a work Sharepoint email link...good thing those spaces are zero-width or they might have screwed something up!

@mcc @megmac @swetland All the ones that translate it to "/tmp" above also do the same with ./. instead of . (not hugely surprising). It gets interesting with other ways of spelling the same thing though:

$ for s in bash zsh dash mksh 'busybox sh' tcsh rc; do echo $s; strace -qqq -e chdir -e signal=none $s -c 'cd ./foo/..'; done
chdir("/tmp/./foo/..")                  = -1 ENOENT (No such file or directory)
chdir("./foo/..")                       = -1 ENOENT (No such file or directory)
bash: line 1: cd: ./foo/..: No such file or directory
chdir("/tmp/foo/..")                    = -1 ENOENT (No such file or directory)
chdir("./foo/..")                       = -1 ENOENT (No such file or directory)
zsh:cd:1: no such file or directory: ./foo/..
chdir("/tmp")                           = 0
chdir("/tmp")                           = 0
busybox sh
chdir("/tmp")                           = 0
chdir("./foo/..")                       = -1 ENOENT (No such file or directory)
chdir("./foo/..")                       = -1 ENOENT (No such file or directory)
./foo/..: No such file or directory.
chdir("./foo/..")                       = -1 ENOENT (No such file or directory)
rc: ./foo/..: No such file or directory

bash & zsh handle it correctly IMO, whereas dash, mksh, and busybox get a bit overzealous and hallucinate the existence of a directory that isn't there (or isn't actually a directory -- the above is unchanged even after running touch foo, aside from s/ENOENT/ENOTDIR/).

@swetland @mcc @megmac Yeah, as alluded to elsewhere in the thread, this is due to the shell doing "unexpected" things internally... cd . doesn't really translate to chdir(".") in most cases:

$ for s in bash zsh dash mksh 'busybox sh' tcsh rc; do echo $s; strace -qqq -e chdir -e signal=none $s -c 'cd .'; done
chdir("/tmp")                           = 0
chdir("/tmp")                           = 0
chdir("/tmp")                           = 0
chdir("/tmp")                           = 0
busybox sh
chdir("/tmp")                           = 0
chdir(".")                              = 0
chdir(".")                              = 0

So the "trick" in question here won't work if you're using rc or tcsh.

Firefox really throwing in the towel on providing anything remotely useful in its error messages.

The greyed-out-but-still-clickable "try again" button is a nice touch too.

firefox saying, literally, "Oops. [...] Firefox can't load this page for some reason."

@shenki Not a lot of information available online that I can see, but from what I can glean from the dts and this page that's a quad 1.6GHz Cortex-A35 with 32K L1 I & D caches, a 512K L2, and probably multiple gigs of memory? Not too long ago those would've been pretty decent specs as a server all its own!

Maybe the host CPU will eventually become redundant and can be depopulated for cost savings...or perhaps the 2700 will need a 2500 or 2600 on the side to manage it in turn.

@arj I've taken to keeping a file called CHECKLIST in my kernel git tree that I run through before taking the --dry-run off of git send-email. Granted, only about 10% of it is specific to the emailed-patches workflow, most of it's just generic "do docs or MAINTAINERS need updates?" and "spellcheck commit messages" kinds of things.

Too many people take infrastructure for granted.

It's not even: "I don't use this, so why should I pay taxes for it?"

It's: "I am completely unaware of the tremendous, heroic efforts that are required on a day-to-day basis to keep civilization running, and me personally safe, healthy, and comfortable, and I refuse to educate myself on the subject - so why should I pay taxes for it?"

The machinery of civilization is becoming ever more complex, yet people are _still_ crying out for "simple solutions", as if there is such a thing anywhere outside of the fevered imaginations of populists.

Fun times with gdb and a Vec named buf:

(gdb): p buf.buf.ptr.pointer.pointer 
$16 = (*mut u8) 0x5555555c9ae0

If only I'd made the Vec a member named buffer of another struct also called buffer.

@cks @dalias Yeah, I end up using shift-right-click often, but was hoping for something that would obviate the need for the modifier.

I see the opposite behavior though -- I've never seen shift-right-click do anything but bring up firefox's "real" native context menu as it should, but upon experimenting with dom.event.contextmenu.enabled=false right-clicking a link in Discord brings up both the firefox menu and Discord's obnoxious in-page one. Alas...

Ozomatli at the Nectar Lounge last night. Realized it's been 20 years since the first time I saw them live; still awesome.

@tedu I haven't used one in any seriousness in some years now, though from the last time I did I recall some wistful sadness at the general feeling that macports was a dying project, losing out to (the IMO markedly inferior) homebrew.

From a skim of those comments it sounds like maybe macports has had some degree of resurgence though? So if in the future I am in fact ever compelled to use a mac again, perhaps at least macports will still be a viable option...

@Obdurodon The slope of the computer-improvement line has really leveled off -- I'm typing this on a computer that's 10 years old, and in 2023 that's basically fine, and aside from some relatively minor performance differences not really noticeably "old". Running a 10-year-old computer in even, say, 2005 would have been laughable.

@stephen0x2dfox Proprietary BMC firmware (especially from a particular three-lettered vendor, it seems) has been and likely will remain for as long as people care to poke at it a wellspring of easily-exploited vulnerabilities, yes.

Open-source alternatives are, I'd hazard an educated guess, likely to be substantially better in that regard, however. I'm hedging a bit here of course because there's still lots of non-memory-safe code involved (though some of us are working on getting Rust integrated), but (a) while there are still likely to be remotely-triggerable bugs, I'd guess they're probably somewhat less numerous/egregious, and (b) enabling some basic protections like ASLR and a non-executable stack at least raise the difficulty level of writing exploits a bit.
