As with all other advice-y sounding things on this site, don't take my word for it. I'm just telling you what worked for me. Use your discretion. I'm not responsible for your actions or the consequences of anything you chopse to do. I'm just saying if you try to clean a stain off suede with vinegar and it winds up costing you a limb or killing somebody, that's not my fault. You're on your own recognizance.
Water is bad for suede. If stains haven't set yet, you can clean them off suede with a rag or sponge soaked in white vinegar. I've had pretty good luck even with stuff that's dried on there pretty good.
As this is a food handling tip, it is presented as documention of something I do. That does not mean I suggest you do it. As with all things, the foremost rule is: use your discretion. I am not responsible for anything you do.
I wish I could remember who showed this to me. This is one of the most useful tips I've ever received. I use this all the time. It even works for frozen-solid inch-thick pork chops. I just did it tonight.
To fully defrost a completely frozen steak in 30 minutes:
1.) Wrap it tightly in something 100% watertight. The watertightness is essential otherwise you will ruin it rather than defrost it. High-quality bags might work in lieu of anything else. 2.) Fully submerge it in a bowl or container of cold tapwater. Put something on top of it to keep it submerged if you…
I had a truly maddening problem where my /embed/ functionality was sometimes returning full pages to CURL commands and online services like redirect-checker.org, etc.
It turned out, it was Yoast's URL parameter stripping. I had failed to update Yoast's settings with some new parameters I was using, and what Yyoast never tells you is that when you're logged in, it lets everything work fine, and only strips parameters for non-logged in users. It just lets you proceed on your way thinking everything is working fine until you can't figure out why curl -I https://mysite.com/blah?param1¶m2 is getting a 301 redirect while https://mysite.com/blah?param1¶m2 is loading fine in your browser. This is especially fun on sites like mine where things like /embed/ and ?embed get written back and forth to each other internally.
I lost several hours to this.
Yoast's docs say there's a way of registering parameters but,…
Richmond-upon-Thames, UK – Nestled precariously on a foundation of questionable architectural decisions and a deep-seated commitment to the unconventional, the Wobbly Wombat Academy stands alone in its unique approach to education. Forget standardized tests and traditional subjects; at WWA, the only constant is change, and the only rule is... well, there really isn't one.
"We believe in fostering a spirit of delightful bewilderment," declared Michael Kupietz, the school's enigmatic Headmaster-in-Absentia, in a recent telegram delivered by carrier pigeon. "Why teach quadratic equations when you can teach the subtle art of competitive cheese rolling? Or the sociological implications of a particularly jaunty hat?"
Indeed, Wobbly Wombat's curriculum reads less like a prospectus and more like the fever dream of a particularly eccentric lexicographer. Mornings might see students engaged in Advanced Cloud Gazing, meticulously cataloging shapes and their potential emotional impact. Afternoons could be dedicated to "Applied Surrealism," where pupils are tasked…
Way back in the heady days of the dotcom boom, as a newbie in San Francisco, I fell in with a group of kids trying to revivify the Cacophony Society via the SF-Caco email list, which, for a while, consisted mostly of a bunch of underemployed young adults kidding around with each other and trying to come up with funny ideas. Finally, one day, a young woman who went by the on-list moniker "Drunken Consumptive Panda" threw out a sentence that was to change a lot of lives: "We should have a pigeon roast in Union Square".
The Union Square Pigeon Roast, as it happens, deserves a much longer reminiscence, is it was the start of a remarkable, brief but fun period of activity that lasted a few years. The event itself was ludicrous: we posed as a group called "Bay Area Rotisserie Friends" (that was…
The problem was, I needed to make some changes to how that code functioned, and I couldn't find where I had added the script that did that.
Long story short: I temporarily added this script to the head of the page, and then reloaded it with an #anchor added to the URL, in this case [code]https://michaelkupietz.com/literally-hundreds-capsule-reviews/#puzzlehead[/code]:

Here's the SQL query to get all post revisions, which I do prior to cleaning them out of the database, which seems to make it much faster:
SELECT p.* FROM [posts table name] p WHERE (p.post_type = 'post' OR p.post_type = 'page') -- Include posts/pages AND (p.post_date BETWEEN '2020-01-01' AND '2029-07-01') -- Adjust date range OR (p.post_type = 'revision' AND p.post_parent IN ( SELECT ID FROM [posts table name] WHERE post_date BETWEEN '2024-01-01' AND '2024-07-01' ));
To get just a count of revisions, change SELECT p.* to SELECT count(*).
I removed a bunch of wildcard paths from rsnapshot.conf's exclude, and suddenly tonight my backup ran in a few minutes instead of taking over a day like it usually does.
Interesting, I've been looking off and on for at least the better part of a year for ways to lighten the load of rsnapshot's under-the-hood rsync backup commands, which reliably took up about half my CPU power almost continuously, and never found this tip before. You can see, plenty of wildcard paths removed, plus a few other things.
Here's a diff, rsnapshot.conf before changes (<) vs after (>): < verbose 1 --- > verbose 4 120c120 < loglevel 2 --- > loglevel 4 143a144,146 > rsync_short_args -Wa > #-W is transfer whole files without prescan, recommended for performance by https://serverfault.com/questions/639458/rsync-taking-100-of-cpu-and-hours-to-complete > #NOTE: if you set the above short…
I had an interesting problem where I set an image's CSS rules to display:fixed and it still scrolled with the page. Here's what I discovered:
In CSS, display:fixed means fixed with regard to the nearest ancestor stacking context, not necessarily to the page coordinates. You can reset the stacking context by adding a transform, will-change, or other attributes (list provided below) to an element. If an ancestor element resets the stacking context, any descendant of it with display:fixed will stay fixed with regard to it, but if it scrolls with the page, will scroll too.
Ditto for the CSS attribute z-index. A higher z-index is only in front of objects in its stacking context. A new stacking context, lower down on the page, can contain elements with a lower z-index but that nonetheless appear in front of it visually, because they're not in the same stacking context.
- added var_dump(opcache_get_status()) to php status page to be able to monitor opcache usage
- changed warning logs from E_ALL & ~E_DEPRECATED & ~E_STRICT to ---- noticed contained a LOT of processes being stopped for tracing turned off request_slowlog_timeout by setting to 0s in had been 4s --- I had turned on lightspeed at 1:45 am est , aug 26. Seems like more problems since then.
None of the above seem to help, still getting freezes maybe every 30 minutes. Next…
I discovered rsnapshot hadn't run in a few days. Checking /etc/rsnapshot.log, I found every recent day had this:
rsync: --delete does not work without --recursive (-r) or --dirs (-d). rsync error: syntax or usage error (code 1) at main.c(1795) [client=3.2.7]
A few days ago I had added the line rsync_short_args -W to /etc/rsnapshot.conf in an effort to get rsync to run without putting such a load on my system. Removing this and running rsnapshot -v hourly from the command line shows that without it, the first line of the rsync command was /usr/bin/rsync -ax --delete --numeric-ids --relative --delete-excluded \, but with it, the first line was /usr/bin/rsync -Wx --delete --numeric-ids --relative --delete-excluded \.
Changing the line rsync_short_args -W to rsync_short_args -Wa, with an a flag explicitly included, solved the problem. Apparently specifying custom short flags overrides at least one of the default flags.
There are intentionally vague broad steps, here just as a reminder to myself; best to look specific instructions for each of these steps up at restore time for the particular system you're restoring to.
A.) Backups should include all user data. Depending on who you ask, that's either: 1.) The entire filesystem except /dev/*, /proc/*, /sys/*, /tmp/*, /run/*, /mnt/*, /media/*, /lost+found (which can be pulled from a complete filesystem backup with rsync -avhP --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /mnt/olddrive/ /mnt/netdrive/) 2.)/home, /etc (except /etc/passwd and /etc/groups, these have useful information to back up but may conflict if written to a new install), /usr/local, /opt, /root, /var (exluding /var/tmp, /var/run/, /var/lock, or /var/spool except you DO want /var/spool/cron/crontabs/)
B.) After copying all the above to the new or restored disk, you need to update /etc/fstab with the new disk UUIDs.
Per numerous references around the web, to delete /path/to/directory-to-delete/:
cd /path/to/ mkdir empty_dir rsync -a --delete empty_dir/ directory-to-delete/ rm -r empty_dir rm -r directory-to-delete

Here’s a guide to all currently available CSS units, with explanations and common use notes. This includes all CSS units listed in MDN Web Docs as of 2025aug15.
I had an interesting thing happen a few months ago where a troll in a chat room decided for some reason to run my site through the W3C's Nu HTML Validator and apparently was grievously wounded by the validation errors it had—and furthermore, had a big concern with the overall bandwidth consumption of the site, with all its images and heavy pages.
Rather than simply solving the problem by not visiting my site, this person apparently felt some sort of imperative to berate me over these things and not. let. it. drop, making the chat room difficult to be in and necessitating action on my part.
So, rather than try to verbally wrangle with a troll, I whipped up a technological solution. And, of course, the monkey in my soul decided to have a little fun with it.
My VWWare VM lost internet connectivity after a reboot. Even the host machine could not access any service on it. Http/https got 523 errors.
I powered down the VM, changed the networking to NAT, powered it back up, shut it down again, changed the networking back to Autodetect, booted it again, and everything seemed fine.
I have always been a dedicated archiver and curator of interesting information: trivia, facts, tidbits, how-tos, items of possible future interest. In the internet age, some of this it makes sense to keep as a public archive: IT troubleshooting information, links and general interest info I want to share with other people, etc.
However, since this site is intended primarily as my creative showcase, this presented me with a conundrum. There are a lot of things I want to share online for various reasons, but which aren't my creative output. And it seemed silly to set up a whole separate website for that.
Hence this "General Reference Library": information I want to make easily available under my own domain, but as a reference, not as my creative output. Eventually this section will just be a colossal brain dump of anything I felt for some reason I wanted to…
"'Literally' is one of the most misused words in the English language. Literally means: exactly as stated. 'I literally rode a horse to get here.' means you saddled a horse and rode it to your destination in real life. 'I literally died laughing' is untrue, because you're still alive." —Siana W., via internet
That's not a question, but I'm going to do my best to answer it anyway.
You're a couple of years behind the times. Dictionaries reflect common language, not the other way around—that's how the meanings of words change over time.
Otherwise "nice" would still have its original English meaning of "foolish or ignorant" (from Latin "Nescire", to be ignorant, also the root of the current but uncommon English word nescience, "ignorance or unknowingness".)
You're in good company, though—Jane Austen mocked the widespread incorrect use of 'nice' to describe things as pleasant in "Northanger…
I've had sporadic problems with clearing the WP cache causing the server to return 520 errors for a few minutes. Usually other sites on the same server are fine, it's specific to this vhost. Logging in via SSH, checking with htop, rsync is usually hogging most of the cpu. Restarting the fpm and then restarting Apache restores the website.
According to https://www.claudiokuenzler.com/blog/361/rsnapshot-backup-reduce-high-load-with-ionice, the big bottleneck with rsync, which rsnaphot runs on, is i/o, not cpu, and rsync can actually tie up i/o such that a web server won't respond to http requests. This can be solved by making the rsnapshot command in crontab ionice -c 3 [rsnapshot command] instead of just the rsnapshot command, which tells rsync not to wait until the disk is idle before trying to access it. So I did. In fact, I made it nice -n 19 ionice -c 3 [rsnapshot command] although…

I don't know if this affects other versions of Photoshop, but on MacOS Photoshop CC 2017 frequently starts unexpectedly graying out all save buttons when you have made changes to your file and should be able to save.
The secret is to resize and move around the dialog. Drag the lower right corner to make it bigger and smaller a few times, and try dragging the whole dialog to the upper left corner of the screen and making it small.
For confused first-time visitors and other people still acclimating, here is a description of these little tabs to the left, as well as some other features of the site.
Open "Expert Mode" CLI Navigation - this give you the option to switch your browser's display to an old-fashioned terminal mode where you may browse this site, view pages and images by typing text commands. Just like how we used to browse the web back in 1978!
Open Visual Settings - This gives you controls to customize the visual display of this website to your liking: turn up or down the brightness, contrast, color temperature, hue, saturation, dark mode, and earthquake. Settings are saved per browser tab, so they will be remembered for your whole visit.
Open My Eyes - Have you ever been engrossed in your work, when you suddenly realize someone is staring at your screen, watching everything you do over your shoulder? If not, this simulates the experience.
Open Help - This help popup, silly! You just clicked it! Do you not remember?
New - Draggable elements! Several elements on this website, including these tabs, this popup message, and the "Hire Mike" badge in the lower right, can be dragged around with your mouse, to avoid them blocking content. Positions are remembered per tab, so as you navigate around the site, they will stay in the same place for your whole visit.
Enjoy!
