• Q&D cmd-line to show dependency graphs for `brew outdated`

    brew outdated -q | while read searchRoot; do
        echo 'checking for '$searchRoot'...'
        outFile=/tmp/$(date +%Y%m%d-%H%M%S)_brew_${searchRoot}.gv
        fullGraph=$(brew deps --installed --dot --graph --include-requirements --for-each --annotate)
        for i in $(seq 1 $searchIterations); do
            newNodes=$(echo "$fullGraph" | egrep " -> \"($nodeList)" | cut -d\" -f2,4 -s | tr '"' '\n' | sort | uniq | tr '\n' "|" | sed 's/|$//')
            if [ -n "$newNodes" ] 
                nodeListNew=$(echo "$nodeList"$'\n'"$newNodes" | tr '|' '\n' | egrep -v '^$' | sort | uniq | tr '\n' "|" | sed 's/|$//')
            if [ "$nodeListNew" = "$nodeList" ] 
        potOut=$(echo "$fullGraph" | egrep "$nodeList" | sort | uniq)
        echo 'digraph {'"$potOut"'}' > "$outFile"
        dot -O -Tpdf "$outFile"
        open "$outFile".pdf

    Code tested on macOS 14.4, with the following extras: brew, graphviz (containing dot)

  • mac file sharing settings cleared

    seems to have happened just after applying the 14.3.1 update (though has happened before):
    all settings missing from the GUI, and sharing -l shows the same - nothing. 😕

    easy enough to re-config - at least after I determined this was the problem, and scratched my head to remember what shares were defined.
    (might want to cron sharing -l, to keep a log of the config)

  • Interesting underscore artifact in recent versions of macOS Terminal

    a thin horizontal line, somewhere before the current cursor…
    it’s apparently a leftover bit of the cursor which (regardless what style cursor you have) displays in the underline format, where a cursor was.
    selecting that line (ex: triple-click) clears the artifact.

  • A refreshingly nuanced look at "AI"

    John Siracusa (famed of exacting investigation and insight) has some excellent ideas - and questions - about “Generative AI”. Which we’re now awash in, whether we know it or not: I Made This.

    My own, entirely separate, opinion:

    There is no AI that exists right now; “Generative AI” is a (marketing) label, for systems created on the backs of people, while giving them no credit - and certainly none of the revenue. Calling it “AI” is - at best - a stretch. And it’s the latest twist (of the blade) in the “gig economy”.

  • Ian McDonald’s “The Little Goddess” is beautiful, brilliant - a page-turner! From The Very Best of the Best. Apparently, a novella from River of Gods - my next stop!

  • wow; I just read my first work by Eleanor Arnason - “Potter of Bones” (in “The Very Best of the Best” anthology) is smart, enchanting, fresh, and I’m looking forward to more!

  • open iftop for each (cfg’d) network interface:

    for i in $(ifconfig -lu); do if ifconfig $i | fgrep -v 'inet 127.' | grep -q "inet [0-9]"; then echo $i; fi; done | while read intfc; do osascript -e "tell application \"terminal\" to do script \"sudo iftop -i $intfc\""; done

    (Mac; could be adapted)

  • Partially-formed process, to convert RTF formatting (ex: lists) from clipboard / pasteboard, to paste into Markdown format (ex: git):

    osascript -e 'the clipboard as «class RTF »' | tr -d '«»' | sed 's/^data RTF //' | xxd -r -p | /usr/local/bin/pandoc -f rtf -t markdown

    (for Mac; could be adapted)

  • strange: when adding a link to an (Apple) Notes document: if the URL has a comma, everything up to the comma is silently stripped (permanently; editing the URL afterward, is too late) - one solution is to encode commas (the first time) as %2C

  • $14 / month - and you better believe you’re still the product 🤮

  • got my first pension check; nice. retiring, is the best (work-related) decision I ever made - LOVING it.
    (BTW: kudos to Cox Auto, for continuing to offer a pension.)

  • reminder:
    that thing you opened you phone/computer for - to be immediately distracted by other notifications? do the first thing FIRST - those notifications will still be there.
    (otherwise, you’ll likely forget the first - likely more important - thing.)

  • Uninstall is sometimes not so simple

    Drat; I’ve been meaning to try the Smile AppleScript editor, but waited too long, and it’s incompatible with modern macOS - HOWEVER:

    I trashed the /Applications/Smile directory (no uninstaller in there), and then re-opened Script Editor to get back to work - but it hung; never completed startup and showed no error messages. Strange.

    After a bit of debugging, I recalled that when I’d installed Smile - since I luckily already had Apple’s built-in Script Editor app open - the Installer told me it had to quit that first. Interesting - and seemed maybe relevant now.

    So I started hunting for evidence of just what had been installed - likely something conflicting with Script Editor (at least).

    /var/log/install.log did have some info, and so did /private/var/db/receipts - which led to the solution (in my case anyway), which was also deleting these directories:

    /Library/Application Support/Smile

    After which, Script Editor was able to finish startup - and even showed the unsaved script that I’d been working on. Nice.

  • ugh: in a dir within iCloud Drive, replacing a regular file, with a symlink of the same name, apparently breaks sync’ing 😟 - and good luck trying to find that via brctl log -w. (only reason I knew it broke: a periodic check of sync status)

  • oh; weird: if you happen to have /tmp open in a Finder window, brew install wget fails with dir_s_rmdir - apparently due to a “.DS_Store” file, a few levels below /tmp

  • Google - the company whose motto WAS “Don’t be Evil”: arstechnica.com

  • Apple Savings: % ain’t bad & it looks like xfer between a linked external account, is much more pleasant (fee-free) than with most others: www.apple.com/newsroom/…

  • macOS Login Items, and other "Allow in Background"

    There are lots of Login Items and other “Allow in Background” items in macOS these days (especially if the Mac is managed…) so it can be useful to get a list of them all - especially when names shown in the GUI, are not clear. The dumpbtm tool is verbose - though generally all you need is this abbreviated list:

    sfltool dumpbtm | grep -E '^([[:blank:]]{0,1}[^[:blank:]]|[[:blank:]]*(Name|URL):)'

  • how to convert macOS clipboard RTF (ex: from Notes.app), to Markdown? this’ll get you 95% of the way there: osascript -e 'the clipboard as «class RTF »' | tr -d '«»' | sed 's/^data RTF //' | xxd -r -p | /usr/local/bin/pandoc -f rtf -t markdown

  • the new legit slacking excuse - and not just for programmers!

    with thanks / apologies to the amazing Randall Munroe - his original: xkcd.com/303

  • How strange: On one Mac I use, when I paste (cmd-V) into the filename field (has focus) in a Save dialog, it suddenly jumps to the Documents folder. On another Mac, it simply pastes, leaving the folder as-is. It apparently does this jump, on any keyboard equivalent (ex: cmd-A).

  • The macOS Weather app can notify for severe weather - it’s Settings window, directed me to Settings > Notifications – but Weather was mising. I stumbled on a solution: Open Notification Center & open Weather from there - it immediately prompted to enable. (C’mon Apple :/ .)

  • I started a Note, with lists of of word / term associations - which make sense to me. Since Spotlight indexes Notes.app, the results come up in that context with everything else, so it’s already started to help me find things more quickly. Might try to integrate with Quicksilver…
