Investigating Leonid's growth
Topic: health, animals Link here

Off to Cape Clear this afternoon for Pene Kirk to perform a biopsy on Leonid's lump in his leg:

The lump proved to be surprisingly hard, more like cartilage than anything else. We'll know more about its nature next week after the pathological investigation, but Pene is sure that it is malignant, and almost certainly some kind of fibrosarcoma.


Phantom files
Topic: technology Link here

While backing up my photos today, came across this strange information:

...
2-grog/.nfs.d7ef1349.29924.4
2-grog/.nfs.d7ef3635.29924.4
2-grog/.nfs.d7ef5a7a.29924.4
...

What are they? /Photos/2-grog/ is a staging directory that I use to make life with Microsoft bearable: put the files I need to process there and run a Microsoft-space program always against the same directory so that I don't have to climb trees directory for directory. The software (in this case DxO PhotoLab) is set to write its results back to the same directory.

But what does that have to do with NFS? I'm using SMB with Samba. Still, some of those timestamps look interesting:

  -rwxr--r--   1 grog  wheel      9304  2 Jan 13:04 .nfs.d7ef5a7a.29924.4
  -rwxr--r--   1 grog  wheel      9304  2 Jan 13:04 .nfs.d7ef3635.29924.4
  -rwxr--r--   1 grog  wheel      9304  2 Jan 13:04 .nfs.d7ef1349.29924.4

Looking back, I found this article. The times match exactly: conversion stopped on 2 January at 12:41, and from 13:05 on I had truncated files.

But what does that have to do with NFS? And it seems that there are many more files there that I can't explain, some dating back as far as August 2013. But on that occasion, as on the others (all more recently in this month), I hadn't noticed any file loss. So at best there's only a partial relationship.

Reheating Mexican food
Topic: food and drink, opinion Link here

On Sunday we ate Mexican-inspired food, including tortillas and frijoles refritos. I made enough for a breakfast of huevos rancheros for Tuesday.

Tuesday? For various reasons it dragged out until yesterday evening (for leftovers) and this morning (for the eggs). How did the food fare?

The tortillas, left in their serving box, got somewhat hard. I ran water over them and left them to soak before heating them in a microwave oven. The result: quite acceptable yesterday evening, though the rolled-up taco fell apart. But that happens with fresh tortillas too, though it didn't with the ones we ate on Sunday.

This morning I used even more water and heated longer (30 s at 1.2 kW for 2 tortillas), and they came out almost as if they were fresh.

The frijoles refritos were even better: add a little water, heat them up, and they were indistinguishable from “fresh”.


distress crash
Topic: technology, opinion Link here

Into the office this morning to process some photos, and found that distress, my Microsoft “Windows” 10 box, had apparently crashed and rebooted during the night:

How did that happen? How do I find out? First, of course, I establish contact with the machine:

Setting up your device? Idiot! Don't you know that it's a computer? Did something go completely wrong? And all these silly settings:

OK, Microsoft, I'll bite. Where do I touch my computer? What do I smile at? You're supposed to know what you're running on. What is this nonsense?

Now how does that work? Do I even want to know? Presumably I must use only Microsoft “devices”. Nonsense!

I can't even be bothered to look at this one. “Premium Office apps”. Clearly it costs money. As a FreeBSD developer I already have a free subscription to some Microsoft service which offers me lots of stuff, and I couldn't be bothered to access it. And security? I already have FreeBSD.

“More secure in the cloud with OneDrive”. Somehow that's an oxymoron. If you want data to be secure, you don't make them Internet-accessible.

I was going to say something nasty about this one too, but it occurred to me that it could be useful. I fear that it could involve lots of tree climbing, but I should take a closer look, some other time.

But why did the system crash in the first place? Ah, not a bug, a feature:

Without so much as a by-your-leave, it had simply installed updates and rebooted. I thought I had prohibited that. How I hate Microsoft!


eureso again
Topic: technology Link here

My system upgrade ground to a halt, not for the first time, a month ago. I ran into an unexpected feature (yes, really) of VirtualBox that gave me what looked like inconsistent disk images. I'm sure that I can work around it, and the feature itself (different views of the same disk on different VMs) can be very useful, but here it's just another way to shoot myself in the foot.

So, how about a real computer? Looking around, I was surprised to discover that I have no fewer than 8 ThinkCentre boxes. Five are in use, one appears to be dead, but that still leaves two. So today I grabbed one of them, put a disk in it, and investigated what I need to do to carry on with last month's image.

The biggest problem was that the disk image is 30 GB in size, and the disk I chose had only 20 GB:

=== root@tiwi (/dev/pts/4) ~ 2 -> gpart show
=>       40  976773088  ada0  GPT  (466G)
         40        128     1  freebsd-boot  (64K)
        168   41943040     2  freebsd-ufs  (20G)
   41943208   20971520     3  freebsd-swap  (10G)
   62914728   41943040     4  freebsd-ufs  (20G)
  104857768  871915360     5  freebsd-ufs  (416G)

That's my typical partition layout: boot partition, root file system, swap, alternate root file system and rest of disk for /home. How do I fix that?

For the moment, 20 GB is enough for /home. So I moved what I needed there. Now I need to remove partition 5 (that's the single digit column in the middle) and create a 30 GB partition there.

And then there's the next problem: the boot partition is only 64 kB in size. As I discovered six months ago, that's not enough. I might be able to fake it on this system, but eureka also only has 64 kB. Probably the best choice is to buy another SSD for the root file system.


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.
