ChatGPT Use Case #1 - May 16, 2024

Just trying to justify my paid-for ChatGPT+ account with a use case that's mildly entertaining to me, generating AI versions of the photos I have.

(BTW, sometimes these Google Photos links seem to expire, so I'll check back later to see if the images still work; if they don't work, I'll have to host it locally.)

Heartbeat - March 18, 2024

In lieu of videos from places I haven't been to, I have below photo that I took last week.

Death Valley - Vegas - Grand Canyon - Bryce Canyon - Hoover Dam Trip, December 2023

Some videos and photos from winter road trip last year, a loop of sort from Death Valley, Las Vegas, Grand Canyon, Bryce Canyon, and Hoover Dam.

We went to a few places in Death Valley; below video is of Badwater, the lowest place in the valley.

And were reminded of God's promise never to flood the valley again.

We waited for a bit by the Sphere, waiting for something interesting to come up, but well, I didn't have the patience enough for that.

Oh. And this is the video from Grand Canyon, our main destination for the trip.

I didn't take any videos at the Bryce Canyon, but I do have this photo of the natural bridge (... to nowhere).

And finally, on the way back, we stopped by at the Hoover Dam and took a tour. Below is the photo from the tour.

We did walk onto the memorial bridge (shown in photo above), and I took below video from there.

Bridge Opening - September 22, 2023

'finally saw the bridge open on the Park Street bridge.

In a related news, I also finally learned how to export a video out of Blender (I've used it before to stabilize videos and track points, but I could only export out frame images that I had to piece together into a video form on another software).

New Phone - July 17, 2023

I got a new phone—although the video quality is clearly no improvement from the previous phone.


BTW, I still have my old phone (one of few things not taken in robbery); the new phone—functionally—replaces the old iPad.

Robbery - June 27, 2023

Header of the first couple pages of the police report relating to what happened on June 27:

I was going to post more of it, but it's got a few stamped marks saying "This copy is for the exclusive use of: Park, B. Neither it nor the information contained hereon is to be furnished to any other person or agency except as authorized by law", so I wasn't sure how much of it I could post to a public place like this—I imagine the minimal portion I have in above screenshot is O.K.

While I would have avoided becoming a victim if I could have avoided it—and I am making a few habit changes to avoid becoming a future victim—I do have a lot to be thankful about. It could have been a lot worse. There were a few items that could have been in my bag when it was stolen, and thankfully they weren't in the bag—one particular item had a large monetary value, would have been a pain to replace it, and was in the bag less than an hour before it was stolen. And thankfully right before the trip where the bag was stolen, I put the item away in a secure place.

Also as far as the timing goes, hey, this was a great time to lose my laptop—two months before I really need it for my work and half a semester after of thinking about replacing it with a newer model but before having actually replaced it with a newer model.

Rainbow - June 21, 2023

Wonderfully designed fountains at the Long Beach Convention Center maximizing the rainbow potential under sunlight: I do think with adequate planning (mid-day observation when the sun is at the highest point) and access to a drone, it might be possible to position the drone to observe a full circular rainbow, the kind you can usually only observe from an airplane flying above clouds.

IT'S ALIVE! - May 19, 2023


Hail! - March 5, 2023

Hail! Hail!

SF Bay Area Waterfront Videos - February 2023

Just a few videos of SF Bay Area waterfront. The videos are taken at different times over the past year; the date of this post is the post date.



New Place - Mid-2022

This post is coming much too late—I meant to add one more video for this but I don't think I'll get to make it after all, so posting what I have now—but better late than never.

I moved! I've spent 16+ wonderful years at my old place (see the video I took below after moving/cleaning all I could), but it's time for a new place.

And what to say about the new place—well, it's larger, slightly; location and amenities are better, for where I am now; and, well, I'll need another 16 years for an apples-to-apples comparison.

Winter Wonderland - December 2021

A simple composite photo from a mid-December hike in a town with the most wonderful winter views.

... just kidding. It's no composite photo; my Android phone might be doing some extra processing on its own, but no additional post-processing was done afterward.

New Domain! - September 2021

This website, bkpark.com, is now available under an additional short URL, bkpa.kr. And, yes, while I would have preferred "bkpa.rk," apparently Sakaria is not a real country and no real-life registrar lets you register domains under .rk TLD. But I think bkpa.kr is almost as good, maybe 91% as much—or is it 19% as much?

In any case, below is the WHOIS query result for the domain now.

A Month of Moon Observations - June-July 2021

Below is a compilation of a month of observations I made this summer, mostly to follow along with my students as they had a semester-long project of moon observations.

I did learn a lot doing this project, mainly how difficult the consistent moon observations are, even in summer in the Bay Area. I knew from last summer that the Moon would basically not be visible for a week around the new moon (July 7 through 12 here). What I didn't anticipate this time around is how difficult to observe the full or gibbous moon can be, because of the typical summer weather pattern in the Bay Area—cloudy morning/night; sunny days (these would be June 24 through July 1; while the weather would turn sunny later in the day, the Moon had already set before then).

Anyways; the full set of photos are in this album.

Power Outage - April 12, 2021

There was a 2-hour power outage affecting my block and a large portion of Berkeley Southside. Below is my contemporaneous response on Twitter.

It's also available here, but I delete my tweets that are more than 2 years old, so the tweet will eventually go away (except in my personal archives that I export yearly). The original quality images and videos are available in this album.

Red Skies - September 2020

The fire season came early this year. And the combinations of smoke and wind conditions created this surreal view. This is photo outside my window. At 9 a.m. album

It lasted all day.

Raining down ash.

It lasted a week, with the red sky being replaced by grey—not the grey of clouds, but grey of smoke particles. This normal photo is the first time—September 15—I saw the blue sky again.

I need a new project - July 27, 2020

I need a new project, one that isn't on Minecraft. Work projects are fine—and OER work is really fulfilling, both when I'm working on it and when I'm reaping benefits of that work in a class I'm teaching—but, well, they are work projects. They are driven by needs of a particular thing I'm getting paid to do, and there is a certain element of it that I don't feel I can call "my own."

Anyways; that is why I'm reviving this long-dormant site back up. I'm too cheap to pay for increased hosting costs, if I want access to dynamic content—like for running Wordpress—which is why I'm editing index.html directly (this could be an opportunity to learn more about CSS and actually build out a structure for a site, from scratch—maybe that should be my project). I do have other places where I can run Wordpress, but, well, nowhere with the degree of control I have over this website (I want this to be a personal project, so as much as I keep my work page up to date, I don't want the project to be based there; I do have a personal journal/notes of a sort on a private, password-protected site that is hosted through Wordpress, but whatever it is I'm up to, I want it to be more public.

P.S. It could easily be that the last update on this page is me just saying that "I need a new project," with no update for months/years on end. Good thing this website isn't search-engine-optimized, except for a terrific domain name.

Note: This is the first post written in this space. I am ordering posts here by chronological order of events, not time of writing, so you will see posts below this post.

Civic Theft of 2019 - July 10, 2019

This is the second time my car was broken into. I just wanted to preserve my contemporaneous response, as well as some photos I took at the time.

Some additional photos I took at the time.

With many thanks to Yes Auto Center, the damage was repaired on the same day I discovered it.

Photos here are in this album.

An unexpected tile at Westminster Abbey - May 16, 2011

This tile was in front of the monument for Sir Isaac Newton in Westminster Abbey.

I have to say, I didn't quite expect to see it, mainly for the reason that, by anecdotes, Dirac was an atheist.

And I'm shamed to say I didn't recognize the Dirac equation (see easier-to-read version on Westminster Abbey website), at least not while I was looking at it (for some reason, I kept trying to link it to something I learned in nonrelativistic QM). Well, in my defense, I've never taken formal QFT ... and chances are I won't.

(I have more photos from my London trip, which I need to put up somewhere at some point.)

Comment on Smoking - May-Jul 2008

Photos in this album.

Smoking Allowed

In the hallway of the dorm Nawojka, where I stayed for 5 weeks in Krakow, Poland, lies an ashtray.

In Krakow, for the most part smokers are allowed to stay indoors, quite unlike Berkeley, where they are not only put outside but at least 25 feet away from doorways.

As much as I don't like smoke (and people who smoke), I just don't think that it's right to legislate common courtesy—so, yes, this is one of the things I liked about Poland.


This picture is to wrap up my comment on "Smoking Allowed".

Last January, city of Berkeley passed a law banning smoking within 25 ft of doorways of public buildings, pushing smokers some 5 ft further away from the buildings.

In practice, I do not disagree with the law—I don't smoke, and as I've had problems with smokers before (I'm allergic), I would like them to smoke as far away from ventilation sources as possible.

But, in principle (and some part practice), I disagree with this legislating of etiquette. Smoking where it would not inconvenience others ought to be common courtesy, and legislations on such issues as this only encourages smokers to do what is minimally required—to straddle the line.

And where it matters, these laws do nothing. I've had problem with people smoking outside the dorm buildings—they were farther than 25 ft from the doorway, but that didn't matter, since they were updraft and the wind always blew all the smokes into the study room. And, in my office in Birge, I often have to deal with smokes coming from below—again, because of the shape of the building, even though the smokers are quite far away from doorways, wind carries it into the area between Birge and Le Conte and up into the offices.

No amount of distance laws will address this problem. No amount of legislation, short of banning tobacco products (which would be at least as stupid as the prohibition), will do anything. And yet, these laws only serve to annoy smokers and discriminate against them.

The money and efforts would be better spent if they would focus on awareness programs (i.e. harms of secondhand smoke, about people allergic to smoke particles, and how to avoid getting others exposed to your smoking), rather than these worthless laws.
