Yep, makes sense, thanks!

Well, learned something today after reading a bit further in the thread:

    ruby -e 'x = "a\n25\n" ; if x =~ /^\d+$/ ; puts "yes" ; else ; puts "no" ; end'
    yes

Good to know.

Unsure what you mean?

    $ ruby -e 'x = "25" ; if x =~ /^\d+$/ ; puts "yes" ; else ; puts "no" ; end'
    yes
    $ ruby -e 'x = "25\n" ; if x =~ /^\d+$/ ; puts "yes" ; else ; puts "no" ; end' 
    yes
    $ ruby -e 'x = "a25\n" ; if x =~ /^\d+$/ ; puts "yes" ; else ; puts "no" ; end'
    no

Also, you'd want to use something that parameterizes the query with '?' (I use the Sequel gem) instead of just stuffing it into a sql string.

Dinky Toys!!! I had Eagles, ships from UFO, a Klingon ship...loved them!

Wow, I did something like that for my senior project back in '94 using Inventor on an SGI workstation.

If you still have IMAP access, thunderbird supports OAuth2 for connecting to O365 IMAP. tbsync for calendar access. Seems to work pretty well currently.

I think that's the major problem with software engineering in general: when is software "done" ?

I have Number-Form and Time-Space synesthesia - helps with remembering numbers and dates:

Would Nix benefit from something like the old CMU depot program?

Consolidating everything you want into /usr/local (exclude packages you don't want). I used to use this at my old job before package managers were ubiquitous.

Interesting - I may have hyperphantasia? Most of my thoughts are accompanied by images, and I can rotate and unfold things. It's so vivid I seem to have two types of synesthesia:

Nothing is "secure or not" - technologies/mitigations are secure against particular attacks. HTTPS is generally secure against passive network eavesdropping, but does nothing to stop local file inclusion in a web app.

Just because there are attacks or ways around a particular defense doesn't mean it's worthless, that's why we have defense in depth.

This works too:

    % cat /tmp/sh
    var=variables
    x=$(
    cat <<EOT
    This string has 'single' and "double" quotes and can interpolate '$var'
    EOT
    )
    echo $x

    % bash /tmp/sh
    This string has 'single' and "double" quotes and can interpolate 'variables'

I get a lot of mileage out of

    command | ruby -e 'ARGF.each { |line| #do stuff with line }'

xclip : https://github.com/astrand/xclip

    (long pipeline that generates lots of output) | xclip

Or even just

    xclip < /some/file

Now paste where necessary.

Hmmm, well that's why I like Ruby and other languages with functional approaches. Method chaining and blocks are very similar to pipes to me.

    cat /etc/passwd | grep root | awk -F: '{print $3}'

    ruby -e 'puts File.read("/etc/passwd").lines.select { |line| line.match(/root/) }.first.split(":")[2]'

A little more verbose, but the idea is the same.

The only reason I have any vague understanding of this article is all thanks to PBS Space Time on Youtube.

It's an amazing series. Must watch if you want to know how much we humans understand about our universe.

Reminds me of the organ banks in Niven's Known Space, Series. Governments made being sent to the "organ banks" the favored punishment for crimes. Also gave way to OrganLegging:

Lovely.

Like so?

    % echo 'one\ntwo\nthree' | sed -e 's,$, four,'
    one four
    two four
    three four

I've found that stevia sweeteners with inulin (not insulin) seen to be beneficial for my gut bacteria. Actually seems to help with "loose days".

Sweetleaf is generally what I use.

One good reason (IMO) for doing "cat file |" is it's easier to grab the command from your history and change it to something like "grep foo file |" rather than if you had run "cmd < file".

Funny, I love Ruby and it's my primary language of choice, but I'm a heretic, using braces whenever I can:

    # events per day
    ndbh.fetch('select ts from tbl').all.map { |row| 
        row[:ts]
    }.map { |t|
        t.strftime('%Y-%m-%d')
    }.each { |day|
        days[day] += 1
    }

(yes this could be conciser)

This is generally frowned on, and I'm sure everyone who likes having this style

   foo
     .map {}
     .select {}
     .blah {}

will frown as well, but it's so much more visually appealing to me, coming from a C/perl background when I first encountered Ruby (many years ago).

Funny how important syntax is. So easy to look at code in another style/language and go THATS NOT RIGHT!!

Seems to me the main difference is that all the particles in the gyro are trying to go in a straight line, but can't due to being a part of a rigid structure. You should be able to tell the difference by dropping a ball bearing. It will land "straight down" if it's gravity, but move "to the side" if it's rotating.
