'cause nuts-n-bolts digital maintenance like this post is about can give a headache

This post is about trimming down the file size of an Adobe Lightroom catalog. In keeping with the off-season them of my previous post (which was filled with fall-foliage photos), this post is sprinkled with a few photos from Kyoto springs past, chosen more for their mentally-calming effect than for photographic quality, which they generally lack. (Sorry)
In a nutshell, if you have a large Lightroom catalog, and if you don't need the detailed editing history for your photos, you might be able to significantly reduce the size of your Lightroom catalog by flushing that edit-history data, which might generally improve overall responsiveness when working in Lightroom.
As one data point, my personal Lightroom catalog holding data for 134,026 photos and videos went from 3.9GB to 1.7GB, a savings of 56%.

Before you can do this, you have to decide whether the edit history is data you don't want to keep. It's a log of every change made in the develop module, as illustrated here:
Lightroom allows you to return the image to any given step by clicking on the step in the list, which can be quite convenient while you're working on an image. But if you're like me, it's of practical use only while actively working on an image. For editing states that I want to save over time, I use either snapshots (such as automatically made via my Snapshot on Export plugin), or virtual copies.
So I personally don't need the step-by-step editing history to be saved for years and years in the catalog, so I hope I'll get some benefit by clearing it out.

Just how much benefit the clearing-out provides remains an open question. It's obviously better to have a smaller catalog file, though I haven't run any quantitative tests to put a number to it as I have in some earlier write-ups (such as I did in “An Analysis of Lightroom JPEG Export Quality Settings” and “A Qualitative Analysis of NEF Compression”).
A reduction in catalog size clearly makes backups smaller and faster, and you are backing up your Lightroom catalog, right? It contains a lot of data that would be painful if not impossible to recreate if you lost it. But one assumes a smaller file makes any of its database access quicker, and so day-to-day interaction with those aspects of Lightroom should, one reasons, be faster
The procedure is easy, but before doing it, it's perhaps interesting to know the size of your catalog file before flushing edit-history data, as a point of comparison with after. To check the file size, first optimize the catalog (in Lightroom, invoke “File > Optimize Catalog...”, exit Lightroom, then check the size of the “*.lrcat” catalog file using Finder or Explorer.
Then make a backup of the catalog file, just in case. You can do so by zipping up a copy in Finder or Explorer, or you can use Lightroom's backup mechanism, though the latter can be excruciatingly slow for large catalogs.

Now to flush the edit-history data. Back in Lightroom, select the images that you want to do this to. I selected everything, but you can select a subset. You might select all but recent photos, for example.
Then enter the Develop module, and invoke “Develop > Clear History...” menu item, and if you've selected more than one image, you'll be presented with a dialog:
Choose “Selected Photos”.
You then have to wait “a while” for the process to complete. Lightroom gives no indication that anything is going on under the hood, but if you have a CPU-activity monitor running, you'll see it working for a while. It's unfortunate that Lightroom doesn't expose this background task's progress so you can know for sure when it's done. If you don't have a CPU-activity monitor, I'll blindly suggest waiting at least a minute for every 25,000 items selected.
You can use Lightroom while this is going on, or just let it sit.
Once you're ready to see the results, again invoke “File > Optimize Catalog...”, exit Lightroom, and inspect the new size.

your catalog file might be much smaller now
Mine reduced to less than half of what it had been, but your results will depend on your own editing history, of course. Lots of local-correction brush strokes, for example, makes for much larger history data, so when clearing it out, for much more savings.
If you chose to do this, how much savings for how large a catalog did you get?

volunteer ground crews at the Shugakuin Imperial Villa (修学院離宮)
Nov 2013, Kyoto Japan
Chatting with a visitor to Kyoto yesterday, she said that she really wanted to see Japan's fall foliage sometime. That prompts me to dip into my archives for a fall-foliage post today, with photos from a visit last November to the Shugakuin Imperial Villa in north-east Kyoto.
It was a brilliantly bright day and even with my polarizer filter (which normally has a wonderful effect with fall colors) the photos seem washed out to me, but some are still not too bad.
This is my second visit, the first having been covered starting in “My First Visit To Kyoto’s Shugakuin Imperial Villa” where I explain a bit about the place.

I'd prefer them to sprinkle more colorful leaves, rather than rake up what's there
As I explain in the post about my first visit, visiting is only by reserved tour, and it moves along at a brisk pace with little time to stop and compose a photo. Knowing this, I moved forward quickly so that I could stop and have a moment before the rest of the group caught up...

tour-guide policeman explaining something to my friend Kentaro Kataoka
Japanese citizens wanting to visit the imperial sites in Kyoto must make reservations far in advance, but a foreigner (non-Japanese) can often make a same-day reservations. Each group of foreigners can bring one Japanese citizen with them, and this time I brought my masseur friend Kataoka-sensei. (Coincidentally, I had a massage from him today to handle a severely-pulled neck/shoulder muscle; the guy is a miracle worker.)

A cake from October 29th, 2008
( placed on this post in 2014 for reasons we'll see below )
Today is the 25th anniversary of my first arrival in Japan.
It was June 19th, 1989 that I flew into Tokyo from California after having finished grad school and then lived with my brothers for several months while waiting for my work visa to be approved. I was met at the airport by Krish Kulkarni, whom I had never met, but had no trouble finding because he's the twin brother of my best friend at grad school, Ram Kulkarni (who later went on to be the best man at my wedding, and I at his).
A day or two later I made my way down to the Kyoto/Osaka region, where I started work as an engineer at Omron Tateishi Denki (オムロン立石電機).
I worked at Omron for about eight years, though spending much of the time in The States at Carnegie Mellon University as a “visiting researcher” (I was really a babysitter for a room full of computers that Omron had donated).
I eventually moved to The States to work for Yahoo!, but not long before I met the woman I would marry. She happened to be Japanese, and after about eight years in Silicon Valley we moved back to Japan, setting up our lives in Kyoto. That was 10 years ago this spring.
Back then, when I first announced it on October 29th 2008, the plugin didn't have any documentation beyond what I wrote on the announcement post. I should have provided complete documentation, but I didn't..... until today. Today, almost six years later, I finally got around to it, and changed the plugin's home page from a placeholder to a long description of all the plugin can do. If you use the plugin, check it out.
So why didn't I write up the documentation when I released the plugin? My Lightroom catalog tells me that I was busy that day with a party at Anthony's preschool for all the kids who had a birthday in October. So, I thought it would be fitting to post a few photos from that 2008 party today...

I was happy to finally get the plugin documentation done today. Some of my other plugins have okay documentation, but perhaps 40 need serious work. Perhaps I'll start on the next in another 25 years...

melts in your mouth
Sirloin at Beefland Prince, Awaji Island, Japan
With Anthony away on a school trip, Fumie and I made a day-trip date to Awaji Island two hours by car south from Kyoto, where our first stop was a late lunch in heaven, A.K.A “Beefland Prince”.

it's served on a slab of very hot stone, so it continues to sizzle for quite some time
You can't begin to imagine how good this steak was. When I say the steak literally melts in your mouth, I'm literally using the word “literally” for its literal meaning... the fats in the meat just melt away. It's almost unearthly when compared to any other steak I've ever had in this life (including the fantastic teppanyaki steak I wrote about the other day; as good as it was, it's not in the same class as today's place).
Sadly, it's a two-hour drive away and is pretty pricey, so we can't enjoy it often. We last came four years ago.
Because I'm a camera geek, check out yet another example of the powerful impact a polarizing filter can have, in these two shots of the chopsticks' sleeve:
mouseover a button to see that image
What a difference.
I used a polarizer on the steak shots above, but only partially because as I wrote about in my first writeup on using a polarizer filter six years ago, a certain amount of shine/glare is usually appealing with food. I've also presented other examples of the filter with: fall foliage moss · wet rocks · a temple garden · lotus flowers · a stream.
Anyway, this was our third time at this restaurant. I thought I'd posted about it in years past, but for the life of me I can't find any evidence. Here are some shots from our last visit four years ago...

Shogunzuka Overlook (将軍塚), Kyoto Japan
We had a brief heavy rain this afternoon a couple of hours before sunset, and so with the clearing air I thought to make a visit to check out the views from the Shogunzuka Overlook, which I haven't been to in a while. (However, the “nearby photos” link under any photo brings you to the bazillion photos I've posted from up here over the years.)
