Privacy: what is it and why do we care? …

In this world where Big Internet firms track you to sell you stuff (and to sell YOU), big Government tracks you because, well, they can, and where I found myself on a motion activated camera when backpacking alone in the “backcountry” in an attempt to “get away from it all”, I’ve spend some time thinking about privacy. Life is short. I could spend a lot of time registering domain names, managing certificates, running my own mail server, de-googling, convincing my friends and family to use nifty new security and privacy apps, and generally fighting the privacy fight as an individual against entire well-funded industries and governments.

AT Hiking 2020: 1500 miles down, 700 to go

1500 miles down, 700 to go to finish section hiking the Appalachian Trail with 215 miles completed this year in 3 trips.

Of course, I have some of the hardest miles left: the Smokies, Mt. Washington, the Whites, the Presidentials, the Bigelows, but with persistence, luck, health, constant gear tweaks (and some HARD hiking) I should finish in a few years.

HOWTO: See SOME lines from a file

Sometimes you want to see the head of a file. Sometimes you want to see the tail. Sometimes you just want to see some lines from a file.

The bash function below gives you some lines:

gmj@ed bash [master] $ cat <<END > lines.txt
> 1
> 2
> 3
> 4
> 5
> 6
> 7
> 8
> 9
> 10
> 11
> 12
> 13
> 14
> 15
> END
gmj@ed bash [master] $ source some.t
sh
gmj@ed bash [master] $
gmj@ed bash [master] $ some -2 lines.txt
14
15
gmj@ed bash [master] $ some -2 lines.txt
9
10
gmj@ed bash [master] $ some -2 lines.txt
6
7
gmj@ed bash [master] $ cat some.sh

HOWTO: /bin/ed by example

Below I show an editing session that uses basic /bin/ed commands.

/bin/ed is the standard Unix Editor

ed was written round 1969. It’s still here. grep comes from /bin/ed: g/re/p works as an ed command to search *g*lobally for a *re*gular expression and *p*rint the matching lines. ed commands will be familiar to users of sed, as sed is the “stream editor” with a very similar set of commands. ed commands will be familiar to vi users. If you type “:” in vi, you get, basically, an ed prompt. You can type ed commands (see below) and they work. “vi” is the “visual interface” to ed (or one of it’s successors). Though I am a die hard emacs user, often when I just want to do a quick edit or take some note I just fire up /bin/ed and go….

There's a lot to be said for climbing mountains

Vulgate (Latin): Matthew Chapter 5

1 Videns autem Jesus turbas, ascendit in montem...

or, roughly (my translation):

Jesus, however, seeing the crowd/mob/political disturbance went up on
the mountain...

The word “turba” per my paper dictionary tends towards a crowd that is politically disturbed. It can also mean an eddy (water) or a child’s spinning top. Per https://en.wiktionary.org/wiki/turba#Latin it means…

Latin Flash Cards in the 21st century (2773 AUC)

Latin flash cards are not what they were in 1983: https://latinlexicon.org. It’s got a thing where you can pop in a sentence (say, one form Cicro or random #Latin conversations on twitter (yes, they exist)), and you can click on the words (yellow above), it shows you all the possible words that particular inflected word might be and then offers to build flash cards for you…complete with citations/examples from the literature….

The History Of Rome - nihil novi

I’ve been listening to “The History of Rome” podcast recently. There is nothing new under the sun: Plagues (er, “pandemics”), riots, xenophobia, wars, greed, ambition, and political factions.

It’s filling in a lot of gaps and details for me. I would recommend if you’re interested in history. Today’s basic problems are not new.
