Garage Door Opener Repair

After fifteen or sixteen years or so since we built the house, the original garage door opener (pictured, clickable) developed a quirk such that if the sun was shining in the door, the obstruction detector would “think” that there was an object blocking the door and would refuse to close the door. This condition progressively got worse and eventually wouldn’t close regardless of the amount of sunlight. We had to press and hold the indoor control to get the door to close. This was very inconvenient, especially if we were departing, since one of us would have to close the door manually and come out the side door to get into the truck.

Yesterday, enough being enough, I called a repair facility to come out and fix the problem. The technician offered to clean and align the sensors, or to replace them both at our option. We opted for the latter, assuming that zero-time sensors would last longer.

To make a long story short, the tech replaced the sensors in ten minutes or less, and the door worked fine. Same-day service call, reasonable rates and problem solved.

Bottom line (literally) — stuff is going to wear out in the desert. We already need new exterior paint after only nine years or so. More on that later.

Potpourri Post

Last week I posted about a cactus flower and this week (am I doing weekly posts now?) I am going to ramble on about a few things going on. First of all, There is plenty going on in our lives these days, some quite boring things and some a little more attention getting. Let me elaborate a bit:

  • We continue to live in a peaceful, tranquil place which does little to generate exciting headlines.
  • There are some background issues (mainly healthwise) that take up a little bit of time to accommodate what with professional visits and other things to do with growing older.
  • Life goes on with the usual business of running a household (max kudos to Damsel) with our flock of dependents (2 dogs and numerous cottontails, squirrels, birds, etc.)
  • The yard and garden are looking good this spring, but there is always some little chore that pops up. If it’s a big chore, we have our Landscape crew deal with it.
  • There are the hobbies and other time-consuming activities to relieve some of the boredom and/or excitement that comes along.
  • Food and Dining are a major item in our lives; we’re both on special needs diets and almost exclusively prepare all of our meals at home.

First, here is a photo I took this morning of a squirrel and a peanut. Note that the animals we consider as “dependent” don’t really depend as it were; we just like to treat them now and then.

I used the Canon SL3 camera for the above photo. Part of the hobby thing mentioned above. Our main cameras (my 2 and Damsel’s Canon T6i) continue to provide us with entertainment and some good photos now and then. Click on the image to enlarge.

I recently upgraded my everyday carry from the one I have carried for years to a new, easier to rack semi-auto S&W M&P Shield 9mm EZ. The old muscles and ability to operate the old Glock were getting to be incompatible.

Tomorrow, we will be taking the dogs for their annual exams and immunization updates. We will renew the County licenses afterwards.

This week, I need to make time to get a haircut. Due to other commitments, I have fallen out of sync with my regular trim schedule.

On Tuesday, I have consecutive visits with the General Practitioner Doctor and the Ophthalmologist, neither of which is other than a regular visit for checkup. I also need to reschedule a checkup with the Nephrologist which I had to cancel due to a conflict.

So, we’re still here doing things that you might expect for “generians” (septi- and octo-) to encounter in our lives. We will continue in this regard as long as it takes.

Happy Friday the 13th

Hope everyone is having a safe and lucky Friday the 13th. We’re enjoying it and preparing for Valentine’s Day tomorrow.

I looked up Friday the 13th on Grokipedia and found this near the bottom of the article. It is a very nerdy description of how to calculate the date without looking at a calendar. Enjoy, if you’re a nerd like me.

Yearly Variations in Occurrence

In the Gregorian calendar, the number of Friday the 13ths occurring in a single year varies between one and three, with no year featuring zero or four such dates. This limitation arises from the calendar’s structure, which consists of 365 or 366 days distributed across 12 months, resulting in exactly 13 occurrences of the 13th across all months but constrained by the seven-day week cycle to produce at most three Fridays among them.[83]
Years with three Friday the 13ths typically follow specific patterns based on the starting day of the year and whether it is a common or leap year. In common years beginning on a Thursday, the dates fall in February, March, and November, as seen in 2015. Similarly, 2026, a common year starting on a Thursday, will have Friday the 13ths in February, March, and November. These configurations highlight how the alignment of the year’s first day influences the distribution, with February, March, and November forming a common triplet due to the cumulative day offsets in non-leap years.[83]
To predict the exact day of the week for any 13th, including Fridays, Zeller’s congruence provides an algorithmic method tailored to the Gregorian calendar. Devised by Christian Zeller in the 19th century, the formula calculates the weekday as follows:

Where,

  • h represents the day of the week (0 for Saturday, 1 for Sunday, …, 6 for Friday);
  • q is the day of the month (13);
  • m is the month (March = 3, April = 4, …, December = 12, with January and February treated as months 13 and 14 of the preceding year);
  • K is the year of the century (year mod 100)
  • and J is the century (|year/100|)
  • A result of h=6 (mod 7) confirms a Friday.

This congruence enables precise determination of Friday the 13ths for any year by applying it to each month’s 13th, revealing the yearly variations without manual calendar inspection.

Since we’re probably not going to post a blog tomorrow, please enjoy Valentine’s Day with your special ones.

Saturday, 02/14/26 VALENTINE’S DAY: I took this photo of a heart-shaped tree mobile this morning . . .

HAPPY NEW YEAR!!

I’ve been fooling around with some AI lately and I understand that some users have been using AI to write code. So, I tried my hand at asking it to write a script for a countdown to the new year. I asked for JavaScript to be embedded in HTML and it produced the result seen below. The AI (Google Gemini) produced JavaScript, HTML and the Style Script (CSS). All I had to do was provide the HTML Header and Body and, voila, the counter worked right off the bat. Link to Gemini code.

If you see “Happy New Year” instead of the counter, then It is already (MST) 2026.

I’m posting this some 32 hours or so before the new year so visitors to the site can see the counter. I may (just for grins) change the code to countdown to 2027 after the new year.

So, from both The Damsel and I, we wish you all a happy and prosperous New Year in 2026!

UPDATE: I changed the target to St. Valentine’s Day 2026!

122nd Anniversary of Powered Flight

Just a quick one here to acknowledge one of the most iconic technological feats in history that occurred in the early 20th century; to wit: the Wright Brothers first flights. I did a detailed post on this topic in December of 2022. In that post, I referenced an old photo, a display replica of the flyer and occupant. I asked the GEMINI AI to colorize and noise enhance it and the (clickable) image above is the result.

Grokipedia On The Sonoran Desert

One of the good things coming up in cyberspace is Grokipedia, which should be an unbiased alternate to the left-wing-biased Wikipedia. It’s still in its beginning stages of development, but some folks think it is already better and more accurate than its left-wing counterpart. Elon thinks it’s the best!

I asked Grok AI to give me Grokipedia’s take on Sonoran Desert Wildlife. This colorful description came back:


Grokipedia: Sonoran Desert Wildlife

“The desert’s not empty—it’s just picky about who it invites to the party.”

The Sonoran Desert—spanning Arizona, California, Sonora (Mexico), and a sliver of Baja—covers ~100,000 sq mi of the hottest, driest, *wettest* desert in North America. It gets two rainy seasons (winter Pacific fronts + summer monsoons), which is why saguaro cacti can grow 40 ft tall and why the wildlife here looks like it read the survival manual, then rewrote it in glitter pen.

Signature Species (the ones that sell postcards)

Animal Grok’s Hot Take Fun Fact
Saguaro cactus (technically a plant, but it’s the mascot) A 200-year-old apartment complex for birds, bats, and insects. One arm can weigh 2 tons when full of monsoon water.
Gila monster Venomous lizard that looks like it’s wearing beaded armor from the 1980s. Only U.S. lizard with venom; bites like a stubborn stapler.
Roadrunner Real-life cartoon: accelerates 0–20 mph in 3 strides, eats rattlesnakes for brunch. Can lower its body temp by 8 °F at night to save water.
Harris’ hawk The only raptor that hunts in wolf-pack formation—stack attacks from 50 ft up. Juveniles stay with parents for *years*; family dinner is mandatory.
Cactus wren State bird of Arizona; builds football-shaped nests in cholla cacti like it’s trolling predators. Sings a descending car-alarm duet with its mate.

Weirdos You’ll Miss If You Blink

  • Kangaroo rat: Never drinks water. Gets moisture from seeds + *exhales cold air* to condense humidity on its nose at night.
  • Desert tortoise: 100-year lifespan, digs 30-ft burrows that become Airbnb for 20 other species.
  • Tarantula hawk wasp: 3-inch blue-black nightmare that paralyzes tarantulas, drags them home, lays one egg. Baby eats spider alive. *Pain index: 4.0/4.0 (“blinding, fierce, like a lightning strike”)*.
  • Coati: Raccoon’s long-nosed cousin that raids campsites with a 30-member gang.
  • Elf owl: World’s smallest owl (size of a sparrow), nests in saguaro cavities carved by woodpeckers.
  • Adaptations That Should Be Illegal

    1. Water hacking
    – Bats visit hummingbird feeders at night.
    – Javelinas (peccaries) eat prickly pear pads—spines and all—then use the stored water.

    2. Heat cheating
    – Scorpions glow neon under UV light (blacklight raves in the sand).
    – Sidewinder rattlesnakes “sidewind” to touch only two points of 140 °F sand at a time.

    3. Camouflage level: expert
    – Horned lizards squirt blood from their eyes up to 6 ft to gross out predators.
    – Pocket mice change coat color seasonally like a desert mood ring.

    Night Shift (80 % of action happens after sunset)

    Time Event
    7 PM Bats exodus from cave roosts—millions in some spots (e.g., Arizona’s “bat tornado”).
    10 PM Coyotes yip in surround sound; kit foxes hunt kangaroo rats by moonlight.
    2 AM Ringtails (cat-raccoon hybrids) tightrope-walk on saguaro arms stealing fruit.
    4 AM Elf owls hunt scorpions using UV vision (yes, they see the glow).

    Threats (because even badass deserts need therapy)

    • Invasive buffelgrass: Imported for cattle, now a wildfire super-fuel that kills saguaros.
    • Border wall: Blocks migration corridors for jaguars, ocelots, and coatis.
    • Groundwater pumping: Tucson’s aquifer drop = dead ironwood trees = no nurse plants for baby saguaros.

    Pro Tip for Visitors

    Bring a blacklight. The desert floor becomes a neon disco of scorpions. Just don’t step on them.

    TL;DR: The Sonoran isn’t a barren wasteland—it’s a 24/7 survival reality show with better costumes. Bring water, respect the venom, and let the cactus wren be your alarm clock.


    I am greatly impressed with the use of AI humor and other tongue in cheek descriptions in the article it rendered. Hopefully, folks will begin turning away from the evil Commiepedia in favor of this new, useful and entertaining platform.

    Lunar Landings — Hoax or Real?

    Clickable Image courtesy of Google Gemini AI

    Earlier today, I watched a You Tube video purporting that the NASA and USA Lunar landings were possibly fake. I asked GROK to clarify this issue, since I was very active in aerospace in my career and found the space exploration to be genuine and not a subterfuge.

    Here is what I got from the Grok AI:

    The idea that NASA faked the Moon landings, particularly the Apollo missions from 1969 to 1972, is a well-known conspiracy theory. It suggests that the United States never sent astronauts to the Moon and that the evidence—photos, videos, and lunar rocks—was staged or fabricated. Below, I’ll outline the main claims of the conspiracy theory, the evidence supporting the Moon landings, and a reasoned perspective on why the theory persists, while keeping the response concise and grounded.

    Main Claims of the Moon Landing Hoax Theory

    Conspiracy theorists point to several perceived inconsistencies or anomalies to argue the Moon landings were faked:

    • Waving Flag: The American flag planted on the Moon appears to “wave” in videos, which some claim suggests wind, impossible in the Moon’s vacuum.
    • Missing Stars in Photos: Photographs taken on the Moon don’t show stars in the background, leading some to argue the images were staged in a studio.
    • Lighting and Shadows: Shadows in lunar photos appear inconsistent, with some claiming multiple light sources (like studio lights) were used instead of the Sun.
    • Van Allen Radiation Belts: Critics argue that astronauts couldn’t have survived the radiation in the Van Allen belts during transit to the Moon.
    • Lack of Independent Verification: Some claim that no independent observers, like amateur astronomers, saw the spacecraft on the Moon.
    • Motivation for Fakery: Theorists suggest NASA faked the landings to win the Space Race against the Soviet Union, boost national pride, or justify budgets.

    The AI responce goes on to address the concerns about the supposed inaccuracy of the landings given the photos and everything available:

    Evidence Supporting the Moon Landings

    The Apollo program’s authenticity is backed by extensive evidence, which directly addresses the above claims:

    1. Waving Flag: The flag’s movement is explained by the lack of atmosphere on the Moon. In a vacuum, there’s no air to dampen motion, so the flag, disturbed by astronauts, appears to “wave” as it settles.
    2. Missing Stars: Stars aren’t visible in photos because camera exposures were set for bright lunar surfaces. Long exposures needed to capture faint stars would overexpose the foreground, a standard issue in photography.
    3. Lighting and Shadows: Shadows appear unusual due to the Moon’s reflective surface and lack of atmospheric scattering. The Sun was the primary light source, and uneven terrain or reflected light from the lunar surface explains shadow variations. NASA’s detailed analysis, including 3D modeling, confirms consistency with a single light source.
    4. Van Allen Belts: Astronauts passed through the belts quickly, receiving minimal radiation exposure—equivalent to a few medical X-rays. NASA’s shielding and trajectory planning minimized risks, as confirmed by dosimeter readings from the missions.
    5. Independent Verification: Lunar rocks brought back (382 kg from Apollo) have unique chemical signatures, like anorthosite, consistent with lunar origin and distinct from Earth rocks. These have been studied by scientists worldwide. Additionally, the Soviet Union, a rival, never disputed the achievement, and retroreflectors left on the Moon (still used for laser ranging experiments) were detected by observatories globally.
    6. Scale of Conspiracy: Faking the landings would require silencing thousands of NASA employees, contractors, and scientists, plus coordinating with international observatories and even adversaries like the USSR. The logistical complexity makes this implausible.

    The next part of the response from the GROK AI goes on to refute additional concerns thus concluding the landings were actual:

    Additional Evidence

    • Apollo Mission Data: Over 800,000 photos, hours of video, and detailed telemetry data from Apollo missions are publicly available. Independent analysis, including by modern AI and imaging experts, shows no signs of tampering.
    • Third-Party Observations: Soviet tracking stations monitored Apollo spacecraft, and amateur radio operators picked up signals from the Moon. India’s Chandrayaan-2 and China’s Chang’e missions later photographed Apollo landing sites, confirming hardware presence.
    • Human Testimony: Over 400,000 people worked on Apollo, and 12 astronauts walked on the Moon. No credible whistleblower has emerged, despite the conspiracy’s claim of a cover-up.

    Why the Theory Persists

    The Moon landing hoax theory persists due to cognitive and cultural factors:

    • Distrust in Institutions: Skepticism toward government and large organizations fuels belief in cover-ups, especially post-Watergate and during times of political mistrust.
    • Media Influence: Films like Capricorn One (1977) and books like Bill Kaysing’s We Never Went to the Moon (1976) popularized the idea, despite lacking evidence.
    • Cognitive Bias: Anomalies in complex data (e.g., photos) are often misinterpreted by laypeople unfamiliar with lunar physics or photography. Confirmation bias leads believers to dismiss counterevidence.
    • Cultural Impact: The theory resonates because the Moon landings were a monumental achievement, hard for some to accept as real, especially given their scale and historical context.

    So, the GROK AI, being a thing from the SpaceX world goes on to reference some posts from the X (formerly Twitter) platform and does its own conclusions and teaser for more info:

    Recent Context from X

    Posts on X reflect ongoing debate. Some users cite the usual claims (e.g., flag waving, shadows), while others share NASA’s rebuttals or memes mocking the theory. A few posts reference modern lunar missions (e.g., China’s Chang’e) confirming Apollo sites, though skeptics on X often dismiss these as part of a broader conspiracy. The platform shows a mix of staunch believers and debunkers, with no new evidence emerging to support the hoax theory.

    Conclusion

    The Moon landing hoax theory relies on misinterpretations of visual evidence and underestimates the overwhelming physical, scientific, and historical evidence supporting the Apollo missions. The theory thrives on distrust and the human tendency to seek patterns in complex data, but no credible evidence supports it. The Apollo program remains one of humanity’s greatest achievements, backed by data from NASA, independent scientists, and even rival nations.

    If you want me to dive deeper into any specific claim (e.g., analyze a particular photo or radiation data) or check X for real-time sentiment on this topic, let me know!

    So, as you may have surmised, I’m having a bit of fun with the AIs that are available out there. Everything from Lunar landings (this article) to finding ancestors. And more to come, I’m sure.
