Shopping again
Topic: general, technology, opinion Link here

Into town again today for the weekly shopping, or at least the rest of it: we managed most of it on Monday. About the only thing of interest was that Google Maps suddenly stopped reporting in mid-message. And that proved to be because I no longer had mobile phone reception!

Drove like that from Sebastopol to PETstock in Latrobe Street. Still no signal. That can't be right. Power down the phone, pop the SIM card and replace, reboot. And yes, I had reception again. What caused that? The phone had recognized the SIMM card before I powered it down, so probably a simple power cycle would have done the trick. Is this indicative of the general reliability of mobile phones, or is this one dying?


No Chevy for you
Topic: food and drink, opinion Link here

Off to Dan Murphy's to buy beer and sherry. They've rearranged things again, and I couldn't find it, so I asked an assistant. “Is that red?”. No, it's sherry. “Chevy? Don't know it”. I had to explain that it was a fortified wine, and she knew that, but only because it was the heading of the area, which is about as far from where they used to be as they could manage in that building.

Somehow drinks in Australia are different from in the rest of the world. While walking through another area, where I had once hoped to find Kirsch, I saw a bottle of “Pear Schnapps”. That might be interesting. But it's not Schnapps at all: it was about 14% alcohol, and who knows what is in it. Paint thinner, like Baitz?


More eBay pain
Topic: technology, general, opinion Link here

While in town, sent off the rain gauge that I finally got round to return. Next step: report it as sent and give the tracking number. But:

It's worth reading the fine print, which contradicts the coarse print. Found a way to access the information after all and enter the tracking number. But what's wrong with these people? A change of generation? It's interesting to note that all people who communicated with me via “chat” said things like:

Hello Greg. I see you opened this account 23 years ago, thank you for your loyalty.

Have I been interfacing with people who are younger than my eBay account?

30 years!
Topic: history, opinion Link here

With the end of last month I have now completed 30 years' worth of daily diaries: 7¾ years from 1 January 1963 to 30 September 1970 (the stub on 1 October 1970 doesn't really count) and then 22¼ years from 1 September 2000 to 30 November 2022.

How many pages is that? Very difficult to say. There were a number of distinct phases:

And then of course there's the medium. In the 1960s it was paper, and from 2000 on it was machine-readable. In each case, from the perspective of the present, the number of pages depend on the browser and how you have set it. But I've done a couple of print previews, and come up with, for the month of November:

Year       pages
1963       20
1967       34
1969       25
2002       9
2006       24
2007       47
2012       77
2017       72
2020       75
2021       89
2022       78

My guess is that I could reckon 30 pages per month in the 1960s, 25 pages from 2000 to 2007 (when I retired) and 75 since then, for a total of 18630 pages (2730 + 2025 + 13875). How does that compare with other long books? It seems that the longest work of fiction is “Marienbad My Love” by Mark Leach, which according to this page has 10,710 pages, or “The Blah Story” by Nigel Tomm, which according to this page has 7,312 pages and is thus considerably longer than “Marienbad My Love”, whose page count they're too polite to mention.

But my diary isn't fiction. What about the Oxford English Dictionary? It wins: the second edition (the last one printed) had 21,728 pages. Still, I seem to be in the same ball park.


Hanging daily cleanup run
Topic: technology, opinion Link here

For the last couple of days I've been getting mail messages like this:

What's that? Off to look and discovered:

That's a lot of stuff, and clearly it points back to Friday or Saturday last week. But what? Considerable discussion on IRC, during which Callum Gibson suggested

cgibson: probably NFS

That made sense. What do we have mounted? I tend to use df rather than mount to show mounted file systems, but this time it didn't help:

=== root@bde (/dev/pts/1) /home/grog 15 -> df
^C^C^C

Yes, looks like Callum was right. So:

=== grog@bde (/dev/pts/3) ~ 1 -> mount
/dev/ada0s1a on / (ufs, local, soft-updates, journaled soft-updates)
...
eureka:/dump on /dump (nfs)
teevee:/ on /teevee (nfs)

teevee! I turned that off for the last time last Friday. Case closed.

=== root@bde (/dev/pts/5) /home/grog 1 -> umount -f /teevee

Oh. Why can't I umount it? And while I'm pondering that, why is the daily run hanging on a dead NFS mount? Spent some time discussing things, during which people came up with a number of tools which I hadn't thought of. Of course rebooting teevee unstuck things.

I wonder why I mounted teevee's root file system on bde.


Summer?

How about that, the spring wasn't colder than average; it was pretty much average, but both the minimum and maximum temperatures were milder than in other years. But of course the rain was much more. The rainfall numbers here are from my weather station and are somewhat on the low side; the real rainfall for spring was

Month       Rainfall
September       70.8
October       286.4
November       166.7
Total       523.9

That's close to the normal annual rainfall.


Luminar after all?
Topic: photography, technology, opinion Link here

I've been looking at Luminar photo processing software for 4 years now, and I've never found a good reason to install it. But it came close. In April this year I considered it to fix the artefacts in this photo and others that I took at the same time:

At the time I discussed the issues in some detail, and also the confusion I had between their two products “Luminar AI” and “Luminar Neo”. The reviews were also not overly encouraging, so I left it.

But now is the black season, it seems: It's been Black Friday for the past 10 days or so. Skylum (the company that makes Luminar) offered me Yet Another special offer for Luminar Neo. OK, is that the one I want? Off looking. It seems that there's no mention of Luminar AI any more; potentially they have merged them into one product, which makes a lot of sense.

So: off looking for tutorials, once again finding nothing of use. Documentation of any kind is clearly not their forte. Is it even worth trying? One review suggested that the “remove power line” tool works quite well up to a point, and presumably it could do a good job on the fence lines.

OK, let's try. I have a 30 day money-back period, so I should really try it out in that time. Off to buy it, in the process discovering that they honoured the discount code SHOTKIT15 that I had picked up from one of the reviews.

Apart from the interesting detail that Skylum from Ukraine is really Shinyfields Limited in Cyprus, there's nothing of interest. Not even an obvious way to page down!

Then it went off installing over the net, giving no indication how long it would expect it to take. Mañana.


This page contains (roughly) yesterday's and today's entries. I have a horror of reverse chronological documents, so all my diary entries are chronological. This page normally contains the last two days, but if I fall behind it may contain more. You can find older entries in the archive. Note that I often update a diary entry a day or two after I write it.     Do you have a comment about something I have written? This is a diary, not a “blog”, and there is deliberately no provision for directly adding comments. It's also not a vehicle for third-party content. But I welcome feedback and try to reply to all messages I receive. See the diary overview for more details. If you do send me a message relating to something I have written, please indicate whether you'd prefer me not to mention your name. Otherwise I'll assume that it's OK to do so.
