Closed port 53 and Port 531 on my home router
Closed port 53 and Port 531 on my home router.
This appears to have killed my subdomains, like my feed aggregator. Will deal with this later when I have time.
Air Fryer Chicken Strips Success
1. Slice three boneless, skinless chicken breasts lengthwise into 1/4"-1/2" (1.27–2.34 cm) wide strips.
2. Put in a large bowl with lots of extra-fine garlic powder and chili powder, and a fair bit of coconut flour. Toss until strips are coated.
3. Sprinkle with soy sauce. Toss some more. Sprinkle some more soy sauce. Toss some more. Don't overdo the soy sauce, but, use a bit.
4. Lay out in air fryer. For this quantity, I had to do two layers: one on the bottom of the air fryer, put in an old foldable/expandable metal vegetable colander over that, and put in another layer of chicken strips. Be sure to leave some space between the chicken strips, typical air fryer stuff. I had to drape some of the top layer over the edges of the colander.
5. Air fry 12 minutes at…
Firefox freezes – tried setting gfx.webrender.software to true
Claude says that following a kernel panic, watchdog reported threads held by Firefox GPU helper, even thought I have hardware acceleration off. I tried its suggestion of toggling gfx.webrender.software to true in about:config.
"The watchdog reports at 13:51:55 and 13:52:30 have 11 and 12 WindowServer waits on Firefox GPU Helper [47166]. The stackshot in the panic file at 13:53:15 shows the same PID, so the chain was blocked for about 80 seconds or more before the panic.
- In those reports that GPU helper had been running about 266,000 s (roughly 3 days) and had a 2,294 MB footprint.
- The panic was probably not a single event. The GPU helper was already stuck, WindowServer was already hanging, and the watchdogs fired before the kernel finally panicked at the 45 s framebuffer timeout."
A Claude incident report was recorded.
How to clear it when restarting MacOS Tahoe brings up a ton of notifications and no “Clear All” button
Today I restarted my Mac OS Tahoe machine and suddenly, when I logged back in, a million old Slack notifications came up. Hovering over them, I did not get the "Close All" button on top, and had to tediously click them closed, one by one.
Turned out, in System Preferences under the Apple Menu, in the Notifications page, if I select "Slack", "Notification Grouping" was set to "None". Setting this to "Automatic" caused all the old notifications to collapse into a small visual "stack" behind the topmost notification, and when I hovered over it, the "Close All" button appeared.
Prefab Cole Slaw Kit, Improved
So, I buy these "cole slaw kits" in the supermarket for a couple of bucks. They're basically a bag full sliced cabbage & a little grated carrot, and include a generous plastic squeeze packet of cheap, chemical-y, over-sweetened Italian dressing. It's enough for 2-3 side dishes, or one decent bowl for one person which can sub for a meal if you're not that famished.
Here's how I fix it:
1. Dump the slaw mix in a bowl. The stuff I buy mostly fills a 16oz soup bowl.
2. Squeeze in 1/2-3/4 of the included "dressing", to taste. I prefer less rather than more.
3. Put in a generous dollop, a pretty big forkful or two, of mayonnaise.
4. Give it a couple of decent tablespoons of vinegar. I use white but red might work. Try to err on the side of not overpowering it... you don't…

FileMaker’s consistency check is not thorough, files can still be corrupt
https://help.claris.com/en/pro-help/content/file-consistency.html - Information that FileMaker's consistency checks are not as reliable as the Recovery function—they don't check as much. (Bear in mind that the recovery doesn't even tell you everything on the front end, you have to read the recovery log to get full info.)

Separation model drawbacks
This is a work-in-progress inspired by a recent conversation.
In the "separation model" in FileMaker, where data tables live in separate files from an "interface file" containing visual layouts that display the data to the user, used to be widely recommended as a development convention. However, many developers have found that it has significant drawbacks. This is a scratchpad list of those drawbacks as I encounter them.
1. Duplicate relationship graphsIn practice, relationships depend on context, and this is provided by table occurrences that layouts are built on. You may need a portal on a layout... that means the relationship must be in the interface file. But you may have a calculated field in the parent record that counts, summarizes, or otherwise performs an aggregate operation on the related records. That means the relationship must be in the data file. Neither of these is unusual at all. So you…
Converted to cloudflare tunnel from ddclient
Today Comcast (boo! hiss!) did some work in my neighborhood and knocked my server offline. I had a long, painful chat session with ChatGPT which ended with me eventually getting set up with cloudflare tunnels instead of using ddclient to update my IP address. The whole chat and terminal session are saved locally in my hard drive in the backups/admin > troubleshooting logs folder in case I ever need to recreate what happened.
Quickly check status/error code of all hosted domains
To quickly check to http return code for a bunch of your hosted domains, enter this in bash:
[code]for host in \ domain.com www.domain.com \ domain2.info www.domain2.info \ domain3.com www.domain3.com do code=$(curl -k -sS -o /dev/null -w '%{http_code} %{redirect_url}' "https://$host/") printf "%-26s %s\n" "$host" "$code" done[/code]
Stop Siri Dictation from automatically adding incorrect punctuation everywhere.
On my iPhone, I had Siri dication suddenly start inserting bogus commas everywhere when I never said "comma". You can turn this off by going to settings > general > keyboard > dictation and turning off the auto-punctuation switch.
Airdropping photos from iOS to MacOS always stuck on “waiting”
If your phone and Mac appear to be able to see each other over Airdrop, but every time you try to send photos from your phone to your Mac the phone sits on "waiting" and the photos never transfer, try picking "Force quit..." from the Apple icon menu in the upper left of your window on the Mac, select "Finder", hit the "Relaunch" button, wait a moment for the Finder to restart, and try transferring again.

Obsidian Annoyances
Here's a CSS customization feature. Have fun getting it to work!
Have to leave the app to customize CSS. Why can't you save snippets in the app?? Overall, it feels like they intentionally make it as difficult and roundabout as possible to use.
And of course I followed the instructions, created the snippet in the secondary text editor Obsidian makes you keep around if you want to do things like this, quit the app, reopened it, and... it didn't work. Because, of course it didn't work. Why would following the instructions WORK, when it's so much more of a waste of time if it doesn't? I'm so glad they made this so complicated. This is so much harder than if they just had a place in the preferences to enter custom CSS, and, who doesn't love things to be as hard as possible?
Edit: After googling, I found

Mike’s Rules Of Design
This is a scratchpad for jotting down the various design rules I use, mostly as I run across violations.
1. No making people read hieroglyphics for core functionalitySomewhere along the way, a lot of people picked up on Steve Jobs's worst idea and ran with it: User interfaces should emphasize looking like something that would look "cool" in a movie, rather than focus on usability. Icons, which were originally meant as a visual cue to help you quickly distinguish functions without having to read text, became monochrome, uniform, abstract, unhelpfully difficult to distinguish from each other, and descriptive text went away so you couldn't know at a glance what they did, leading to millions of man-hours wasted mousing over 20 buttons in a row trying to figure out which one was the "import" button. As a design language, icons went from unique and identifiable to the visual equivalent of…

A uBlock Origin custom rule to hide “Related Videos” (and more) on YouTube
If you're like me, you loathe and despise the toxic mental ordure that YouTube often plasters up and down the right side of each video page, such as POLITICAL DEMAGOGUERY in MIXED CAPS to PIQUE your OUTRAGE enough to KEEP YOU WATCHING YOUTUBE instead of doing something PRODUCTIVE! [insert thumbnail of someone looking amazed here.]
At a certain point, I started to notice that there was more likely to be things I didn't even want to know existed in that section than anything I actually wanted to see. So, I added a simple rule to the uBlock Origin browser plugin that hides that section of the page:
[code]!https://www.youtube.com www.youtube.com###related[/code]
And that's it. That's all you need to add. No more "related videos" section.
While I was at it, I added a rule to block the "suggested videos" thumbnails that appear at the end of videos, by…
Detect SYN flood slowing down server with netstat
If the web server is slow, detect a SYN flood by netstat -ant | grep :443 | grep SYN_RECV to show the IP addresses leaving it hanging. Hint: If you're behind a reverse proxy, and that shows IP addresses that aren't the proxy's, then your IP is being hit directly. To find out how many IPs are hanging, do netstat -ant | grep :443 | grep SYN_RECV | wc -l. If you do it a few times and the number is increasing, you may be under attack. If it's over 100, that's suspicious, but manageable and the server can usually handle it, especially if you have SYN cookies activated. If it's over 1000, you're under attack.

Things That Don’t Get Firefox To Start Loading Pages Again When It Decides It Doesn’t Want To
Firefox as of v 148 (actually a bit earlier than that, but that's what I'm on right now) frequently decides not to load pages anymore. You enter a URL or click on a link and get the status message "Waiting for [URL]..." and you can wait as long as you care to.
When this begins, your only choice is to restart Firefox.
Here is a list of "solutions" to the problem from around the web, which I have tried and found do not fix the problem:
• Turning off DNS-over-HTTPS in Firefox Settings
• Flushing MacOS's DNS cache.
• Going to about:networking and clearing Firefox's DNS cache
• Going into about:config and changing network.dns.disableIPv6 from false to true
• Opening in "troubleshooting mode" or disabling all extensions
• Turning VPN off
• Turning VPN on
Playlist shortcodes not working in Chrome because Lightspeed cache is set to defer jquery
Long story short, I got a message from a user that audio playlists were working in Firefox but not Chrome. The Chrome console had an error that "jQuery" wasn't defined, but typing jQuery into console did show a function definition. Turns out, in Lightspeed Cache's JS Delayed Includes, I had entered the word jquery by itself on a line, with a note to myself that something was causing a browser flash if I didn't do that. But removing this made the playlist shortcodes work on Chrome again. Ergo: don't defer jQuery.
iOS Shortcut to dictate your shopping list into Reminders.app
I uses this shortcut to dictate my shopping list into the iOS Reminders "Shopping" list. It breaks spoken lists on the word "and" to create separate shopping list items.
So I might run the shortcut, say the phrase "pickles and hot dogs and mustard", and it will add "pickles", "hot dogs", and "mustard" as separate checkbox items to the Shopping list in Reminders. It's handy for rattling off my shopping list as I'm staring into my fridge.
Obviously you need a list called "Shopping" set up in your Reminders app.
This shortcut executes the following steps:
- Dictate text - listens for spoken input. Make sure set to '''stop listening after pause'''.
- Split
Dictated TextbyCustomand- splits the text into a list with "and" as the delimiter - Repeat with each item in
Split Text- begins the loop that adds…

SSH into local mac, error “WARNING- REMOTE HOST IDENTIFICATION HAS CHANGED!”
SSHing into a local MacOS machine at address "macbook.local", I suddenly got this:
[code]@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Xbar/BitBar gives “Couldn’t Posix Spawn” for script.
Apple's quarantine system can cause this. Try
[code]chmod +x com.apple.quarantine /path/to/script.sh xattr -d com.apple.quarantine /path/to/script.sh[/code]
In my experience only the xattr is needed but the chmod might help and couldn't hurt.
If CSS animations cause a layout shift during rendering, even if they’re on compositable attributes
If CSS animations cause a layout shift even if they're on compositable ettributes, look for clip paths, overflow:hidden, or css filters on them or their ancestors.
