Frijoles refritos?
Topic: food and drink, opinion Link here

Cooked another batch of frijoles de la olla (boiled beans) today. They're intended to make frijoles refritos. In principle I'm happy with my recipe, but can it be improved? One thing that occurs to me: it contains lard, something that makes the beans unsuitable for vegetarians, Jews and Muslims. But why? Frying the beans also takes (significantly more) lard. Why not add it all then?

Off on the web looking for Spanish language recipes to avoid the US American bean paste. And how about that, I found this page, which goes into significant detail. It agrees with me that the beans should be crushed, not puréeed, so it must be right. But there are a number of details that I didn't know, including adding onion and garlic. And it doesn't mention anything specific about boiling the beans. I'll look at it again next time I fry.

Huevos a la tigre: omelette?
Topic: food and drink, opinion Link here

Huevos a la tigre for breakfast today. It's really a kind of omelette. Or is it? Not after my once-non-stick frying pan had its way:

Mobile phone power consumption
Topic: technology, general, opinion Link here

I've been playing more than usual with, my new Xiaomi Redmi Note 13 mobile phone. And the power consumption differs markedly from, my old Redmi 9T. And it shows in the power consumption. Here first albo, then hirse (run the cursor over an image to compare it with its neighbour):

Is the Note 13 really that much hungrier than the 9T? Or is it just that I have been using it more?

Understanding Microsoft issues with VirtualBox
Topic: technology, opinion Link here

Saturday's installation of Ubuntu confirmed that there wasn't much wrong with the VirtualBox network configuration on hydra. OK, what's the issue with Microsoft? Spent some time investigating.

First, can it be that the VMs didn't like the host configuration changing under their running image? Rebooted despise. No improvement. OK, for the fun of it, try the “troubleshooter”, which has never shot any trouble for me. But this time it came up and said “done!”, specifically “restored default gateway”. That's nonsense, of course: I was trying (and failing) to ping the default gateway. But of course I tried again anyway. And it worked! Fixed, but with the wrong explanation.

OK, on to disaster, the other clone, almost exactly the same configuration bar the memory size. This time I didn't reboot. And though it claimed to have fixed the problem, this time it didn't. OK, reboot. And yes, it tried to fix it again, but set up DHCP. Maybe that's what it did before, and I didn't find it because I was looking for disaster, not dhcp-242. But after configuring the interface on the Microsoft side to the correct IP address, I wasn't able to ping eureka. Run the troubleshooter again. “Ethernet 2” (there is no “Ethernet 1”) didn't have a valid IP configuration, whatever that means. It fixed it. At some asynchronous point I had connectivity again.

While pondering that, discovered that I could no longer contact despise. Another fix, then ran a ping from eureka for both VMs. That was instructive. After about 3 minutes, I got:

64 bytes from icmp_seq=177 ttl=128 time=0.313 ms
64 bytes from icmp_seq=178 ttl=128 time=0.302 ms
64 bytes from icmp_seq=179 ttl=128 time=0.258 ms
64 bytes from icmp_seq=196 ttl=128 time=13397.802 ms

64 bytes from icmp_seq=199 ttl=128 time=10389.815 ms
64 bytes from icmp_seq=200 ttl=128 time=9388.793 ms
64 bytes from icmp_seq=201 ttl=128 time=8387.910 ms
64 bytes from icmp_seq=202 ttl=128 time=7386.827 ms
64 bytes from icmp_seq=203 ttl=128 time=6385.940 ms
64 bytes from icmp_seq=204 ttl=128 time=5384.064 ms

64 bytes from icmp_seq=206 ttl=128 time=3380.054 ms
64 bytes from icmp_seq=207 ttl=128 time=2377.515 ms
64 bytes from icmp_seq=208 ttl=128 time=1375.960 ms
64 bytes from icmp_seq=209 ttl=128 time=373.828 ms

And then nothing. The ping times are interesting: they're at one second intervals, so basically the response to ICMP sequences 196 to 209 all happened at the same time (24 ms between all of them). And it was preceded by 17 dropped packets.

Does this happen with despise too? At first I thought that it didn't, but after a good 2 hours I had:

64 bytes from icmp_seq=8018 ttl=128 time=0.603 ms
64 bytes from icmp_seq=8031 ttl=128 time=18192.978 ms

64 bytes from icmp_seq=8039 ttl=128 time=10117.802 ms
64 bytes from icmp_seq=8040 ttl=128 time=9113.875 ms
64 bytes from icmp_seq=8041 ttl=128 time=8050.493 ms
64 bytes from icmp_seq=8042 ttl=128 time=7047.142 ms
64 bytes from icmp_seq=8043 ttl=128 time=6046.126 ms
64 bytes from icmp_seq=8044 ttl=128 time=5044.124 ms
64 bytes from icmp_seq=8045 ttl=128 time=4030.953 ms
64 bytes from icmp_seq=8046 ttl=128 time=3029.581 ms
64 bytes from icmp_seq=8047 ttl=128 time=2023.347 ms
64 bytes from icmp_seq=8048 ttl=128 time=1014.190 ms

Here the response times are not quite as close, but clearly it's the same syndrome.

So: my best bet now is that there's really something wrong with Microsoft on VirtualBox, and it's probably related to the hangs that I had with the old network card, which never had any issues except with this combination. Whose fault is it? Microsoft? VirtualBox? FreeBSD (the interface with VirtualBox)? Time to try other alternatives.

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.
