News from the Linux-adoption front

Well, now. This is interesting: A study of corporate Linux adoption polling 1,275 IT professionals says:

Linux desktop roll out is easier than expected for properly targeted end-user groups

Those with experience are much more likely to regard non-technical users as primary targets for Linux. The message here is that in practice, Linux is easier to deploy to end users than many imagine before they try it.

It’s become fashionable lately to be pessimistic about Linux’s future on the desktop, but I have to say this matches my experience pretty well. The handful of Ubuntu deployments I’ve done in the last couple years for end-users have indeed been easier than one might have expected.

Engage the balonium generator, Scotty!

I enjoy a game called “Commands and Colors: Ancients”, which I’ve blogged about here before. It’s a simulation of tactical ancient warfare that uses special dice to resolve battles. In any given battle you can consider each six-sided die to have faces labeled with the symbols Miss, Miss, Hit, Sword, Helmet, Flag. To improve my play, I decided to generate and study a table of the odds of getting a specified number of hits when a specified number of dice is rolled. I set out to write a Python program to do this.

There are special circumstances under which flags and helmets convert to hits, so the program actually needs to print out several tables and is not entirely trivial. Still, it is computing on a mathematically simple model with strictly bounded computational cost – except for war elephants. These units have the special ability that when they roll a sword, the sword is counted as a hit and then rerolled. (This may make more sense if you think of a sword roll as representing impact damage.) You keep rolling and marking hits as long as the die keeps coming up swords.

To calculate the non-elephant probabilities I enumerated eight entire state spaces for each of 1 to 8 dice (the most you can ever roll under the rules – takes Alexander the Great or Julius Caesar leading a Heavy unit with the the Clash of Shields +2 bonus active), then counted up instances of each distinct outcome (so many misses, hits, swords, flags, banners) to assign a probability mass to each.

(Statisticians often think in terms of probability mass or probability weight, which has to be conserved as a distribution changes. It’s analogous to thinking of electricity as a fluid.)

I then had to write code to mutate a copy of each distribution according to the elephants’ sword-reroll rule. To do this, each outcome containing a sword hit needs its probability mass divided by six and reallocated to itself and five other outcomes with one fewer sword apiece; you stop reallocating when the probability mass on a sword-containing outcome drops below a very low noise level.

That particular piece of code gave me more trouble than the rest of the program put together. At one point I grumbled to a friend who had been following the project “I’m having persistent bugs in my probability mass reallocator.”

He looked right back at me and said, with a perfectly straight face, “Have you considered reversing the polarity of the neutron flow?”

Irrational Expectations

The reactions to my posting on the economic case against the GPL reminded me yet again why failure to understand basic economics often becomes more toxic in people who think they understand a bit about the subject. In this mini-essay, I’ll take a look at the most important (and misleading) of the superficially clever arguments I saw in responses.

RMS issues ukase against Software as a Service – and I agree it’s an iffy idea

In a recent O’Reilly interview, Richard Stallman utters an anathema against software-as-a-service arrangements, calling them “non-free” and saying “you must not use it!” It would be easy to parody RMS’s style of uttering grave moralistic sonorities as though he were the Pope speaking ex-cathedra, but I’m going to resist the temptation because I think in this case his concerns are quite valid.

Freeing technical standards

I grew up on Internet RFCs, so technical standards issued under licenses that forbid free redistribution offend me. Every such document, whether intentionally or not, is a device for hindering open-source software projects and privileging closed-source developers with big budgets and lawyers to hand.

They offend me even more when (as, for example, when the GPS reporting standard NMEA 0183) the proprietary “standard” is so badly designed that a mob of crack-addled rhesus monkeys could have done a better job – and for this they want me to pay? They offend me the absolute most when the “standard” is distribution-restricted, expensive, badly written, and its topic is a safety-critical technology – so that people could actually die because some jerk wants to collect a trivial amount of secrecy rent on a standard that was crappy to begin with.

Fortunately, there is a way to monkeywrench the organizations that perpetrate this sort of thing – and I’ve spent a substantial part of the last couple of weeks doing exactly that. I’m writing about it here to encourage others to do likewise.

Please forget to FLOSS

In email to a third party, copied to me, Linux activist and long-time friend Rick Moen comments on the acronym FLOSS (usually explanded “Free, Libré, and Open Source”.

I continue to find it difficult to take seriously anyone who adopts an excruciatingly bad, haplessly obscure acronym associated with dental hygiene aids. We learned in the late 1990s a number of lessons about how not to market free / open source, and the idiots who keep coming up with bad ideas like “FLOSS” and “FOSS” are determined to rush, like urban-legend lemmings, off the very cliff of PR incompetence that we so painfully learned to finally avoid, a decade ago. I’m sorry, but those people need to be cluebombed and routed around until they stop shooting at everyone’s feet.

I couldn’t have put it better myself, so I’m not going to try.

Near as I can figure, the only appeal this term has is a sort of lily-livered political correctness, as though people think they’d be making an ideological commitment that will cause petulant screaming from a million basements if they pick “open source” or “free software”.

Well, speaking as the guy who promulgated “open source” to abolish the colossal marketing blunders that were associated with the term “free software”, I think “free software” is less bad than “FLOSS”. Somebody, please, shoot this pitiful acronym through the head and put it out of our misery.

Rick adds:

The problem with [FOSS and FLOSS] isn’t merely that that they sound like goofy nutjob organisation investigated by Emma Peel and John Steed. Worse, it is that neither term can be understood without first understanding both free software and open source, as prerequisite study.

That isn’t merely gross marketing failure; it’s a semantic black hole that sucks marketing into it, never to be seen again. It’s a finely executed study in nomenclature incompetence – and I can’t help noticing it’s promoted by, among others, the same crowd who were doing such a masterful job of keeping free software an obscure ideology prior to 1998.

Er. Yes. Quite…

Why GPSes suck, and what to do about it

I’m the lead of the GPSD project, a service daemon that monitors GPS receivers on serial or USB ports and provides TPV (time-position-velocity) reports in a simple format on on a well-known Internet port. GPSD makes this job looks easy. But it’s not — oh, it’s decidedly not — and thereby hangs an entertaining tale of hacker ingenuity versus multiple layers of suck.

The sound of empire falling, episode 2

From “200 Laptops Break a Business Model” in the pages of the New York Times:

So who’s up, who’s down and who’s out this time around? Microsoft’s valuable Windows franchise appears vulnerable after two decades of dominance. Revenue for the company’s Windows operating system fell for the first time in history in the last quarter of 2008. The popularity of Linux, a free operating system installed on many netbooks instead of Windows, forced Microsoft to lower the prices on its operating system to compete.

Mene, mene, tekel, upharsin!

Master Foo and the Nervous Novice

There was a novice who learned much at the Master’s feet, but felt something to be missing. After meditating on his doubts for some time, he found the courage to approach Master Foo about his problem.

“Master Foo,” he asked “why do Unix users not employ antivirus programs? And defragmentors? And malware cleaners?”

Master Foo smiled, and said “When your house is well constructed, there is no need to add pillars to keep the roof in place.”

The novice replied “Would it not be better to use these things anyway, just to be certain?”

Master Foo reached for a nearby ball of string, and began wrapping it around the novice’s feet.

“What are you doing?” the novice asked in surprise.

Master Foo replied simply: “Tying your shoes.”

Upon hearing this, the novice was enlightened.

The sound of empire falling

I predicted years ago that what would eventually do Microsoft in was white-box PC makers defecting because they needed to claw back profit margin as the Windows license became the largest single item in their bills of material.

And here’s the confirmation I’ve been awaiting: Microsoft Missing Netbook Growth as Linux Wins Sales. The boring biz-journalism headline is guarding some startling facts.

Linux-Hater’s Blog, considered

One of the advantages of having helped found the open-source movement that I cherish most is that nobody can criticize me when I criticize it. I’m a gadfly by nature, disgusted by cant even (actually, especially!) when it’s my own insights being reflected back at me as dogma. Anyone who actually does that is likely to flip me into full Discordian rascal-guru mode.

So I was actually pleased to learn of the existence of Linux-Hater’s Blog. I rather looked forward to winnowing through it for nuggets with which I could shock the more fanboyish members of my community by agreeing. Alas: when I finally went there with intent to read, I discovered that the never-actually-identified author of the blog had ended the project. I read the entire archives anway.

Open Source — Can It Innovate?

There’s an argument commonly heard these days that open-source software is all very well for infrastructure or commodity software where the requirements are well-established, but that it can’t really innovate. I laugh when I hear this, because I remember when the common wisdom was exactly the opposite — that we hackers were great for exploratory, cutting-edge stuff but couldn’t deliver reliable product.

How quickly people forget. We built the World Wide Web, fer cripessakes! The original browser and the original webservers were built by a hacker at CERN, not in some closed-door corporate shop. Before that, years before we got Linux and our own T-shirts, people who would later identify their own behavior correctly as open-source hacking built the Internet. (I was part of the tail end of that process myself; sometime I’ll blog about how and why the domain-name gold-rush is arguably my fault.)
