    ‘J.T. Tavistock,‘ arsa Bhatson.

    “Tavistock ainm an tiarna talún,’ arsa Greta.

    ‘Is dócha gur chuir an tiarna talún troscán éigin agus maisiúcháin áirithe ar fail don tionónta,’ arsa Bhatson.

    ‘Dodo, Watson. Can you read what is written about it?’

    ‘J.T. Tavistock,’ said Watson.

    ‘Tavistock is the name of the landlord,’ said Greta.

    ‘The landlord probably made some furniture and certain decorations available to the tenant,’ said Watson.

A couple notes on Ancient Greek Astronomy

Leave a reply

Following up on these posts:

Today I read Beyond the Book (and What the Greeks Knew About the Earth) in which Professor Matt Strassler explains one of the ways the ancient Greeks knew that the Earth was round and how one of them (Eratosthenes of Cyrene} was able to make a reasonably accurate calculation of its circumference. This calculation assumes that the Sun is much further away from the Earth than the Moon, and hence much bigger, than the Earth of the Moon. Which is Bigger, the Sun or the Earth? Check it Yourself! explains how the Greeks knew this.

The 1945 bombing of Dresden

Leave a reply

When I saw the title ‘Accepted’ History Has Dresden Wrong., by Marc Dauphin, I feared the worst. Usually when I read about someone disagreeing with the conventional version of a well known historical atrocity, the authors are trying to minimize the death toll, or even deny that it happened, e.g. holocaust deniers. However, this article is different.

More on the garage sale laptop

Leave a reply

I have worked some more on the HP Pavilion g6 Notebook I bought for $30 at a local garage sale. I did get the additional RAM I mentioned there. It seemed easy enough to slide into place, but I have not yet been able to get the machine to recognize it. So for now I am stuck with just 4GB. Not long ago that was considered plenty, and I was very happy with a 4GB system, but now “they” are saying you should have at least 16GB on a PC. So now I am looking at lightweight Linux systems to see if I can get some more life out of this system.

    “Mná den chineál céanna a mheallann fear ar leith i gcónaí,” arsa de Hoilm. ‘Titeann sé i ngrá le stuaire fhionn, agus stuaire fhionn a mheallfaidh arís é. Thaitin mná easlána le Burr. Taom croí a thug an chéad bhean chun siúil. Taom croí a thug an dara bean chun siúil. Ní chuirfinn féin spéis sa chás, ach bíonn Bhatson cíocrach chun bleachtaireachta.”

    ‘I admit that I was uneasy,’ said Watson.

    ‘Women of the same sort always attract a particular man,’ said Holmes. ‘He falls in love with a handsome blond woman, and a handsome blond woman will attract him again. Burr liked sick women. A heart attack made the first woman go. A heart attack made the second woman go. I myself would not be interested in the case, but Watson is eager to investigate.

A Note on the Kensington Runestone

Leave a reply

Mia McDavid, my wife, suggested that I look at Geologist unearthed a mystery, then landed on TV in our local newspaper. It was about Scott Wolter, who believes that the Kensington Runestone is a genuine medieval artifact. I am generally skeptical of fringe scholarship claims. The reference to the Knights Templar immediately set off more alarms in my head.

Debian Notes

1 Reply

I recently watched Red Hat: why I’m going all in on community-driven Linux distros. from Veronica Explains, after which I decided to try to seriously use Debian 12 rather than Ubuntu in my daily computer work. This is working reasonably well. I have run into a variety of differences, but so far I have overcome them. A lot of these have to do with Gnome. I have learned a lot about Gnome in the last few days, chiefly how little I actually know about it.

Installing Debian 12 on another laptop

1 Reply

I found an HP Pavilion g6 Notebook at a local garage sale. 64 bit system, 4 GB RAM, 600 GB hard disk, Windows 7 Home Premium edition. $30. It did boot into Windows 7, but I had mixed results when trying to access internet sites. This may be because Windows 7 is obsolete and no longer supported. Given that I decided to install Linux. The Debian 12 installer did not recognize the Windows installation. This may be because the hard disk is MBR and there were already 4 primary partitions. I might have been able to manually rearrange the partitions and add an extended partition, but that process would have been tricky and it simply was not worth the bother for Windows 7, so I let the Debian installer wipe the drive. With Debian there were no problems connecting to the internet and my configuration process worked perfectly. I really do not need this laptop, but the price was hard to resist and I enjoy computer necromancy.

Windows hibernation file

Leave a reply

I discovered the C drive on my main Windows 10 system was almost full. I was not expecting this, since I use Linux most of the time. A lot of the trouble was a file in the root called hiberfil.sys, taking up 13GB. This is used if you want to hibernate your Windows system, and needs at least 40% of your RAM. I never use hibernation, I simply disabled it in an administrator command window with

powercfg -h off

and the file disappeared, as described in How to Disable Hibernation on Windows 10. I also moved a few large iso files to other locations and now have a comfortable amount of free space on the drive.
