The National - You were a kindness

I was in a fog,
I didn’t notice everything
Was coming all apart inside of me
There wasn’t anyway for anyone to settle in
You made a slow disaster out of me

There’s a radiant darkness upon us
I don’t want you to worry
I was careful but nothing is harmless
Baby, you better hurry

You were a kindness when I was a stranger
But I wouldn’t ask for what I didn’t need
Everything’s weird and we’re always in danger
Why would you shatter somebody like me?

Gnus now unbelievably speedy

When I initially revisited Emacs, I used mu4e (instead of Thunderbird) for my email.

I used the wonderful Gmane service to read mailing lists in Gnus and Elfeed to read blogs and RSS feeds within Emacs.

This worked fine but after a while it became a little tiresome having to remember different key bindings to essentially perform the same repetitive tasks; reading messages, navigating (next/previous) messages, moving messages, saving messages, marking messages, deleting messages, searching messages, forwarding messages, replying to messages and occasionally composing brand new messages.

life with Emacs

birth

At the tantalising climax of the last episode, I was invited by Steve for a whistle-stop tour of Emacs.

Steve explained that the main reason he used Emacs was pure laziness. Naturally, this immediately got my attention. He explained:

‘I’m lazy. It’s not a fault. It’s a fact. Most decent programmers are lazy. You’re lazy’.

‘Hang on, just a minute ! What do you mean - I’m lazy ?’

‘Andy - you alias ‘cd ..’ to ‘up’ and ’l’ to ’ls -ltr’. Just to save five characters typing. So don’t tell me you’re not lazy. Anyway, it’s not a criticism’.

life before Emacs

the early years

1962

Entered the world as I intend to leave it. Kicking, screaming, naked, held upside down by a nurse slapping me on the backside.

a night at the Lesser Free Trade Hall

1977

Wrote my first basic program in BASIC on a Tandy TRS-80. Editing facilities were fairly limited. I think to modify Line 10, you had to simply re-enter Line 10. In its entirety. This was rather time consuming, tiresome and almost put me off computers for life.

extending Bash history

I have used the Unix bash shell for many years. As I am incredibly lazy and forgetful, I have become accustomed to using ctrl-r ‘find’ to find and scroll though the latest ‘find’ commands I have issued.

Occasionally, I noticed that a lengthy, complex, useful ‘find’ command’ (which I mercilessly plagiarised from a clever person via Google) was no longer in my shell history.

Investigations revealed the default bash history is a paltry 1000 commands so I decided to increase this to 10000 by adding the following line to ‘~/.bash_profile’.

adventures with FreeNAS

I had been contemplating and researching the purchase of a dedicated Network Attached Storage (NAS) for a long time. Initially, I considered a few different options; an entry level unit like a Synology DiskStation, a small server like the HP Gen 8 Microserver or Dell T20 and installing the disks or even buying the individual components and building the unit myself.

However, I’m pretty useless with hardware and as a NAS should be high quality, reliable and solid, I decided to purchase a ready made unit.

FA Cup Final

On Thursday, a friend offered me two unwanted corporate tickets for the FA Cup Final at Wembley. I gleefully accepted and offloaded the second ticket within minutes.

Saturday dawned cloudy and overcast. I realised I’d planned the journey for a traditional 3pm kick-off. I had the tickets in my hand although it was a bit weird for something so valuable and sought after to be printed out on my mate’s cheap inkjet printer. No holograms, no watermark - just plain A4 paper from WH Smiths.

optimising Emacs and elfeed

I recently had to re-install my work laptop with Oracle Linux 7. With backups, it didn’t take too long to reinstall. The most time consuming task was compiling Emacs 24.5 from source. Emacs 24.5 is required for the excellent Prelude starter kit I have recently adopted. There are a lot of pre-requisite packages for Emacs that are available (but not included) in Oracle Linux 7.

As part of the ‘Emacs for Everything’ experiment, I have also started to use an Emacs package called ‘elfeed’ to read RSS feeds and while it worked in my new, shiny environment, I noticed it ran much slower then previously. I tracked this degradation to the fact that OL7 ships with a dated version of ‘GnuTLS’ (3.3.8 released in September 2014) whereas the latest version is 3.4.9 (released in February 2016).

Code highlight example

This is the famous ‘Hello world’ program written in Python in colour using Markdown.

#!/usr/bin/env python
import sys

def hello(name='world'):
    greeting = "hello " + name
    print(greeting)

if __name__ == "__main__":
    hello(*sys.argv[1:])

This took me a long time to get working.

how mu4e changed my life

Getting email

No mail. In three whole days. Weird. I wonder if it’s Thanksgiving over in the States. Not even any football related banter. Is this thing even on ?

Then I realised precisely why I was sitting alone in an island of blissful isolation, devoid of all email communications and staring at an Inbox in a perpetual state of ‘Zero’.

I had forgotten to configure inbound email.

When I was testing, I used mbsync to synchronise emails from my ISP which worked well (fast, reliable, well documented) with bi-directional sync between IMAP and my local Maildir.
