I’ve reached a very nice resting point in the ongoing effort to develop a very useful, powerful, stable, and cool computer setup.
This started a while back when I built a computer. In particular, this computer. There are several advantages to building a computer. You can save money or get more bang for your buck even if you don’t pay less. On the saving money side, maybe you have components on hand that you don’t have to buy. I did, mainly mass storage. The case I had, thinking I’d save money there, ended up not working out. You get more bang for the buck because the parts you buy will be better than the ones in the equivilant off the line but cheaper computer, and you’ll have more control over what happens in future upgrades.

Or, at least, I’m surprised that this earlier implemented solution has not been mentioned in all the discussion about NSA spying.
Richard Stallman invented an approach to obviating the NSA’s attempts to spy on email. He included it in emacs, the world’s greatest text editor. Here how it works, from the manual. The “M” is the “alt” key (for all practical purposes) and “M-x followed by a word implements the command attached to that word.
32.6 Mail Amusements
M-x spook adds a line of randomly chosen keywords to an outgoing mail message. The keywords are chosen from a list of words that suggest you are discussing something subversive.
The idea behind this feature is the suspicion that the NSA1 and other intelligence agencies snoop on all electronic mail messages that contain keywords suggesting they might find them interesting. (The agencies say that they don’t, but that’s what they would say.) The idea is that if lots of people add suspicious words to their messages, the agencies will get so busy with spurious input that they will have to give up reading it all. Whether or not this is true, it at least amuses some people.
You can use the fortune program to put a “fortune cookie” message into outgoing mail. To do this, add fortune-to-signature to mail-setup-hook:
(add-hook ‘mail-setup-hook ‘fortune-to-signature)
You will probably need to set the variable fortune-file before using this.

That is from the current, on-line emacs manual but it also appears in my hard copy of the manual which I believe dates to the last quarter of the 20th century.
I just reconfigured my laptop with a new system (a form of Linux) and, almost as important, a new power brick. That second item may be more interesting than it sounds for some of you; I’ll write that up later. This change also meant trashing my emacs configuration file. I didn’t have to trash it, of course, but it made sense to do so. I don’t use my laptop in any way that requires that I pay attention to data saved on it. It is a data-free appliance. Sort of. Or, at least, if I took the hard drive out of it and put it in a blender, I would not lose anything important other than a blender which would surely break. In order to achieve this state, I manage certain data not by backing it up but by ignoring it. If I toss the hard drive and put in a new one and install a new system, my emacs configuration file(s) can be gotten off of another computer. Or, preferably, just recreated from scratch.
Why would I want to recreate my emacs configuration files from scratch? Because a) it is fun and b) with the newest version of emacs, a number of things that required excessive messing around with before have become normal. Thus, the configuration files are less cumbersome and easier to manage.
In case you are still reading this post about emacs (good for you!) but don’t know much about it let me explain a few things. If you are already an emacs expert, you may want to skip down to my .emacs file and get right into ridiculing it.
emacs is the best text editor in the world for a number of reasons, but mainly because pretty nearly everything is configurable, and it is very cleanly associated with a very powerful programming language that you can write programs in to make your emacs text editor do amazing things like manage your email, carry out sophisticated statistical analyses on data, make coffee, or stand in for an operating system. Or, you can do like I do; find where other people have written these things and graciously made them available for others to use.
But emacs also suffers from a logical conundrum I call The emacs Paradox. Here is how it goes:
emacs is wonderful because you can configure it any way you want.
emacs keybindings (what happens when you press certain keys) are the most efficient possible therefore you must not change emacs keybindings.
We know this is an interesting paradox because right after hearing all about how emacs keybindings are wonderful, the first thing you will be told to do if you read the introductory material on emacs is to swap the caps lock and control keys, and the second thing you will be told to do is to replace the alt key with any one of a number of alternatives “so you won’t have to squish up your fingers” while executing “meta” commands. This duality (’emacs is perfect ’emacs is flawed) is part of what makes emacs a religion.
That’s the guy who invented emacs.
OK, back to the point. emacs out off the box is probably pefect for some people. emacs with two or three hundred lines of elisp code in various files, some compiled, is perfect for others. But I use emacs to write, not program, so my needs are met by the out of the box version with a hadnful of changes.
My emacs file is below, and it is annotated to make it clear what each step does. This is all hand-codedd. Many of these changes can be made by selecting configuration options from the emacs menu.
Included in the file are a few comments of possible additional changes I may or may not make. I’m agnostic as to whether these changes are worthwhile; I go back and forth. The comments are in there as reminders.
The file is called .emacs and resides in the home directory on a Linux computer with all the other “dot” files, which are by default hidden from view in many file managers (unless you specify otherwise).
And here is mine (UPDATED to make CUA work better within emacs and between apps:

I have a small laptop that I carry to the coffee shop for writing. It is a bit shaky in the hardware department, very small, and has no functioning wireless. The hard drive is encrypted. These attributes together make it the perfect laptop to carry around between, say, the gym, the coffee shop, the grocery store, Huxley’s daycare, etc. I have a small number of files synced on it via a hard wired network connection at home so there is quasi-real time work to do with it, but only a subset of the larger number of files and folders I regularly use. The lack of an Internet connection means that I am not distracted while writing, the low value of the hardware means it won’t matter if it gets dropped, crushed or even stolen, and having the hard drive encrypted with a killer password and such means that the very valuable data (as if) that is on it can’t fall into the wrong hands.

After a little messing around with interesting emacs goodies, we might as well get right on to the good stuff.
emacs uses a concept called “modes.” You’ll learn about that if you use emacs. For now, what you need to know is that there are “major modes” and “minor modes” and we’re only interested in major modes at this moment. There are several major modes that make emacs highly useful for specific purposes, and some of those modes are designed with writing in mind, such as the text-mode the outline-mode and what is known as muse-mode. But writers really want to use org-mode and not much else.
