Getting Web Browsers Not To Blur Images on Retina Screens

Unfortunately this must be set by site, but on retina screens on MacOS, many browsers blur small images, such as 88x31 buttons.

You can overcome this, at least for the images on your site, by adding this CSS to your site:

img, div {
image-rendering: optimizeSpeed;
image-rendering: -moz-crisp-edges;
image-rendering: -webkit-optimize-contrast;
image-rendering: optimize-contrast;
image-rendering: pixelated;
-ms-interpolation-mode: nearest-neighbor;
}

You should add any element that might have a CSS background image property to that selector. In this case I have added

because I have many divs with background images on this site.

How to fix if the “Save” button is grayed out in Photoshop CC 2017 save and export dialogs

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.

This fixes it for me.

Draggable Elements WordPress Plugin

Nothin' But A Drag: Draggable Elements WordPress Plugin

First, the demo

This is a brief demo page for my KupieTools Draggable Elements WordPress plugin, which dynamically adds interactive draggability to any page element, based on CSS class names (or, really, any CSS selector).

Here's some boxes:

Drag Me Horizontally Drag Me Vertically Drag Me Anywhere Drag Me To Corners

If you select "View Page Source" on this page in your browser, you will see that the above four DIV elements, as defined in the page HTML, are just ordinary DIV elements with a single classname, an ID, and some visual styling. The KupieTools Draggable Elements plugin adds draggability to any arbitrary page element, by simply specifying a class name or other CSS selector for it in the plugin. (If you use your browser's Inspector instead of View Page Source, you'll see the current state of those elements, with any changes or additions the plugin created…

Filtering LinkedIn Posts, Notifications, and Comments by keyword

I use the uBlock Origin browser plugin to filter my LinkedIn Posts, Notifications, and Comments to hide anything containing objectionable topics. uBlock Origin allows you to add custom rules to block web content.

How to use and setup uBlock Origin is beyond the scope of this post. It's not hard, figure it out and then come back. What you want to know how to do is add your own custom rules.

Let's say, for purposes of these example, I want to block all mentions of someone named Grump.

The simplest version: block a single word

The following three rules hide Posts, Comments, and Notifications, respectively, that contain the word "grump", whether as a separate word, or as part of other words, such as "grumpier".

Posts: www.linkedin.com##div:has( > .ember-view.occludable-update:has(div.fie-impression-container:has-text(/grump/i)))
Comments: www.linkedin.com##.comments-replies-list > .comments-thread-entity > .comments-thread-item > .comments-comment-entity--reply.comments-comment-entity:has-text(/grump/i)
Notifications: www.linkedin.com##div[data-finite-scroll-hotkey-item]:has-text(/grump/i)

Deactivating, deleting, and completely removing a plugin that WordPress won’t let you deactivate

I installed the WordPress plugin LWS Optimize, which turned out to be unusably broken (which is the reason I'm not linking to it) and made my site unusable. To make matters worse, when I tried to deactivate it, it told me it deactivated... and was still active. I went in through FTP and deleted the plugin folder entirely, and then WordPress said it had been deactivated because it couldn't be found... and it still showed as present and activated in the plugin list.

So I added this to my theme's functions.php file:

add_action('admin_init', function() {
$active_plugins = get_option('active_plugins');
$plugin_to_remove = 'lws-optimize/lws-optimize.php';

if (($key = array_search($plugin_to_remove, $active_plugins)) !== false) {
unset($active_plugins[$key]);
update_option('active_plugins', array_values($active_plugins));
}
});

I then reloaded an admin page and removed that. That deactivated the plugin in the plugins list, but then when I hit the "delete" link, it said it…

Website returns 503 server errors, but no errors in logs

Had a weird one today. Last one website of the several of on this server suddenly started returning 503 (service unavailable) errors. There was nothing in the PHP error log or Apache error log. All server configs are already thoroughly optimized for performance. Other websites on the same server were functioning normally.

I didn't notice this at the time, but my uptime monitor didn't report an outage. When I used redirect-checker.com to check the status code, it returned 200, which should have been a clue, also.

Next time, before doing all sorts of arcane troubleshooting:
1. Try with a different browser
2. Is there a CDN? Try bypassing it.
3. Are you using a VPN? Try selecting a different endpoint (VPN server) if it will let you, or turning it off.

How to monitor RAM for tuning pm.max_children

How to monitor RAM usage:

  1. free -h:

    • This command shows your system's total, used, and free memory in a human-readable format.
    • Key metrics:
      • total: Total RAM.
      • used: RAM currently in use.
      • free: Unused RAM.
      • buff/cache: RAM used for file system buffers and page cache. This is good; Linux uses free RAM for this and frees it when applications need it.
      • available: The most important metric. This estimates how much memory is available for starting new applications without swapping.
    • Run it before and after: Run free -h before you increase max_children and then after your server has been running for a while under typical load with the new settings. Compare the available memory.
  2. htop (recommended if installed):

Add or change /etc/cron.d/sysstat to this. This creates a cron jobe to write file /tmp/outage_resource_log.txt that keeps minute-by-minute stats, sometimes useful in troubleshooting slowdowns.

Word Salad: Vocabulary List

An unsorted list of words or phrases that I like.

Aposiopesis (pron.: /ˌæpəsaɪ.əˈpiːsɪs/; Classical Greek: ἀποσιώπησις, "becoming silent") - a figure of speech wherein a sentence is deliberately broken off and left unfinished, the ending to be supplied by the imagination, giving an impression of unwillingness or inability to continue.[1] An example would be the threat "Get out, or else—!" This device often portrays its users as overcome with passion (fear, anger, excitement) or modesty. To mark the occurrence of aposiopesis with punctuation, an em dash (—) or an ellipsis (...) may be used.

Monological belief system - a self-sustaining worldview comprised of a network of mutually supportive beliefs, such as conspiracy theories which are supported by other conspiracy theories.

More Wild Styles: By Request, Wild SF & Wild NYC (Work In Progress)

A cousin of mine was helping work on a volume of poetry and asked if I had more images specifically of San Francisco or New York City in the style of “Wild California” Studies — AI Generative Art gallery that they could consider for inclusion. I didn't, but I whipped some up.

I'm pretty fond of how a lot of them turned out, but, as with so many of these projects, I wound up making many that are visually striking but don't really have much artistic value beyond that, and the work remains to be done to winnow down all the striking images to the ones that really are special.

Until then, I'm so fond of them, though, that I thought I'd give a preview. Here's the complete output of those experiments, awaiting the best of it being culled down into the final presentation.

Mike Kupietz, Arctic Explorer — Bio

Michael Kupietz (1848-1922) was a pioneering British Arctic explorer best known for his controversial claim of discovering a tropical paradise at the North Pole and his unorthodox expedition methods, which included training polar bears to pull his sledges while playing the bagpipes to "keep their spirits up."

Kupietz began his career as a professional umbrella tester in Manchester before becoming inexplicably convinced that the Arctic contained vast deposits of marmalade. His first expedition in 1880 was funded entirely through the sale of his revolutionary "frost-proof tea cozy," which he insisted was essential Arctic survival gear.

During his most famous expedition (1885-1887), Mike Kupietz allegedly survived for six months by teaching himself to photosynthesize like a plant, claiming the Aurora Borealis provided sufficient light. He documented discovering a colony of Portuguese-speaking penguins (despite penguins being native to the Antarctic) and mapped what he called the "Great Northern Hot Springs Resort," which…

Mostly sticking this placeholder into the "works in progress" section to remind me to pull all my recipies together and work on my cookbook.

I had this idea at the time that it would be fun to put together a bachelor's cookbook of all the different things I made out of those few ingredients.

Over time my culinary palette grew, horizontally if not in terms of sophistication, but the idea never left me. Now there's an air fryer on my counter (or, as I call it, the "meat microwave"), probably more than 5 things I use regularly on my spice shelf…

Bio of Pioneer of Extraterrestrial Research: The Extraordinary Life and Mysterious Disappearance of Michael Kupietz

Michael Kupietz's obsession with the unknown began on a moonless night in 1952, when as a ten-year-old boy in rural Montana, he witnessed what he would later describe as "a dance of lights that defied every law of physics." This experience, combined with his discovery of his grandfather's extensive collection of astronomical observations and unexplained phenomena reports, set him on a path that would eventually revolutionize the field of extraterrestrial research.

Growing up in proximity to several military installations, young Kupietz developed a keen interest in distinguishing conventional aircraft from more unusual aerial phenomena. His mother, a librarian, encouraged his methodical approach to research, while his father, a meteorologist, taught him the importance of eliminating natural atmospheric explanations before considering more exotic possibilities.

After earning degrees in physics and atmospheric sciences from MIT in 1964, Kupietz pioneered the use of multiple-sensor arrays for tracking unexplained aerial phenomena. His innovation lay…

Flying High Again: Breaking Barriers in the Sky: The Extraordinary Life of Mike Kupietz

Michael "Lightning Mike" Kupietz's remarkable journey from a small-town dreamer to one of aviation's most influential figures began on a dusty farm in Kansas in 1934. As the son of a crop duster and a mathematics teacher, young Mike grew up with both aviation fuel and analytical thinking in his blood. His father's precarious aerial maneuvers while protecting local crops would entrance the boy, who spent countless hours perched on fence posts, studying the intricacies of flight dynamics through the practical lens of his father's aging Stearman biplane.

During his early years, Kupietz demonstrated an uncanny ability to understand complex systems. While other children played with toy planes, he was sketching detailed technical drawings and conducting wind tunnel experiments with homemade models in the family barn. His mother's mathematical influence proved crucial, as she taught him to approach flight problems through the lens of physics and geometry, skills that would…

I have to be honest. I don't know about this one.

I set out to do another set of AI-assisted lyric illustrations, this time all of one song in its entirety... Bob Dylan's "Visions Of Johanna".

I got a little ways into it, and it was going well, when a few times in a row the generative algorithm overemphasized cats I had added as incidental background elements in the prompt, to interesting effect. So I had the brilliant idea: let's illustrate the whole song with cats. I backtracked and started over again.
