Boxen

Agglomerations of copper and silicon labouring under my yoke:

schizo
My current desktop box. An eight-core CPU, hence obviously a split personality.
blackwidow
My netbook
chainsaw
My hifi stereo player (I like heavy metal)
pi
Raspberry Pi perpetually running for long-term low-intensity downloads and spidering
estimator
Isn't all numerics just guesswork? Now defunct, some parts having been reused for chainsaw

Opinions

Computing for the masses (1)

"I will also nail to the wall the hide of anyone who talks about Exhibit A outside this room, because there are hardware superweapons and there are software superweapons, and we don't know what Exhibit A is, yet. For all we know it's a piece of hardware that looks like a portable shower cubicle then turns round and installs antique Microsoft crashware in your thalamus."

(From Jury Service by Charles Stross and Cory Doctorow)

Computing for the masses (2)

"Do not use Microsoft Word. MSWord uses code to represent commas, quotes, etc. If you try to paste Word into our HTML editor, the code shows up instead of the punctuation.

For example: "Hey Joe! What's up?"

Will look like this: 8200; What&8221;s u;

Which makes us say "Hey, Bill Gates! &*@# you, you @$$ &*@#!" And want to reject your story.

Word Perfect pastes fine into everything else, so it's not like it has to be difficult. Microsoft just sucks and wants us to use their lousy HTML editor, which our Web Goddess hates, on account of it's just a bunch of bugs with a line of code wrapped around them."

(From the Quantum Muse submission guidelines)

Command names

Any command of more than 5 characters is not worth using.

Software packages

Any package with more than 10 (ultimate) dependencies is not worth installing.

Programming languages

"The usual intent of [verbose languages] is that they be as English-like as possible, on the theory that they will then be easier for unskilled people to program. This intention comes to grief on the reality that syntax isn't what makes programming hard; it's the mental effort and organization required to specify an algorithm precisely that costs. Thus the invariable result is that 'candygrammar' languages are just as difficult to program in as terser ones, and far more painful for the experienced hacker."

(From the candygrammar entry of the jargon file)

Truth

"News is what somebody wants to suppress. Everything else is advertising."

(Variously attributed, possibly by Lord Northcliffe, legendary English newspaper publisher 1865-1922)

Conspiracy theory

A hypothesis which violates the human propensity for wishful thinking.

Democracy

"... The people hate the lizards and the lizards rule the people."

"Odd," said Arthur. "I thought you said it was a democracy."

"I did," said Ford. "It is."

"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't people get rid of the lizards?"

"It honestly doesn't occur to them," said Ford. "They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government they want."

"You mean they actually vote for the lizards?"

"Oh yes," said Ford with a shrug, "of course."

"But," said Arthur, going for the big one again, "why?"

"Because if they didn't vote for a lizard," said Ford, "the wrong lizard might get in. ..."
