College Reunion

I spent the weekend of June 16-19 at Carleton College. The occasion was my 50 year class reunion, for which I was a member of the gift committee, which in turn was a part of the overall planning committee. Mia (my wife) and I had a room on the third floor of Watson Hall, “3rd Watson” was how we would have referred to it back in the day. I don’t know if the current students refer to campus locations like that. I lived on “6th Watson” my senior year.

Duinnín agus an Bótun

Dineen and the Mistake

Botún, pl. -i, a smith’s paring knife; an unfledged bird; misfortune, irreparable mistake; ní raibh aon bhotún. ‘na béal nuair d’ith sé an fheoil … rinne mé mo bhotún …

    den gheolaí mór le rá, an t-aindiagaí Abraham Tomkins, sa Leabharlann Náisiúnta.

    ‘Umf,’ a d’fhreagair Abraham.

    ‘Fágaimis Dia as an áireamh, cad ann a chreideann tú?’ a d’fhiafraigh an Duinníneach de.


    ‘Ahem!’ said Dineen to the eminent geologist looming behind him, the atheist Abraham Tomkins, in the National Library.

    ‘Umf,’ answered Abraham.

    ‘Let us leave God out of the reckoning, what do you believe?’ Dineen asked him.

Time in Windows and Linux

By default, Windows assumes that the local system clock is set to local time, and updates it accordingly. Ubuntu Linux assumes that the clock is running UTC (essentially Greenwich Mean Time) and will update it on that assumption. Since it knows your location (you specified it at installation, and hopefully updated it when you moved) it will display the correct local time just like windows.

The problem comes when you have a dual boot (Linux and Windows) system. When you reboot from one OS into the other the new OS will assume the system clock is behaving according its own rules, even though the other OS was following its rules. To fix this:

Years ago I started making a knife from a file. I put the project aside, but when Mia and I started watching Forged in Fire earlier this year I was inspired to pick it up again.

Free42 on Ubuntu

I noted in Slackware Diary that I had installed Free42 under Slackware. As I wrote in 2006 I fell in love with HP calculators and their RPN notation back in the 1970s, and still find the conventional algebraic notation rather awkward. I no longer carry a physical calulator, but I have Free42 installed on my phone and my tablet, and on my Windows systems. Now I also have it on Slackware. So I circled back to see if I could install in on Ubuntu.
