A new era begins...

I began putting a period to a blessed life pre-Unity today at work as I relegated my primary development host, running Ubuntu Maverick Meerkat, to second fiddle while I picked up and am now playing (identical HP hardware) on Precise Pangolin with Unity (12.04LTS).

I really do not like Unity as compared to Gnome. I develop software and I can't see how using Unity helps me do that better than using Gnome. Mostly, it gets in my way.

And chasing Unity off and restoring Gnome isn't fun and easy, nor was it altogether successful the time I tried it last November. I don't just want Gnome, mind you, I want it exactly how I've had it and I could not reach that point in the few hours I allotted to the experiment. I also don't want to have to hack every new OS I install, so before fleeing Ubuntu altogether, I'm going to see how badly my productivity is afflicted by Unity.

So here I am with about half my crucial development tools running on the newer operating system and the ones that don't still running under Maverick. Principally, I can't get Remmina to work and I need it to replace tsclient. I'm also struggling with Thunderbird in some ways. Today I finally got it set up to do my HP mail, but then it refused to do my personal mail.

The reason for this bothersome detour from productive life? Lucid Lynx LTS expires next April. Maverick already expired last April.

At home I'm going to be undertaking much the same journey if with less angst about how fast and well it works.

A good office sometimes...

...or sort of: it's all relative, n'est-ce pas ?

Not since Novell have I enjoyed a view like this one. Of course, there I had a hard-walled office all to myself whereas here I live in cubicle hell. Here you see I-15, the cities of American Fork and Pleasant Grove as well as Mount Timpanogos.

In the dark foreground is my visitor chair and a couch. As my manager shares this cube with me, we have our (small) team meetings here.

PBS Fund-raisers...

I see PBS has gone back into fund-raising mode again.

Is there anything in the universe more incongruous than a PBS fund-raising drive?

What's on PBS during fund-raisers? Shows that are never part of normal programming. Cheap, popular psychology by two-bit therapists. How-to-get-rich pitches by speakers whose fortunes come from writing books and giving pitches on how to get rich. Opinionated, anti-fat nazis who just want to tell you how you should eat food that no one else eats. Chefs that can't cook their way out of a paper bag that's been soaking in warm water for 24 hours.

Really? PBS fund-raisers drive die-hard PBS fans such as myself to discover "normal" television or turn away to put more time into books (where more of my time is deserved anyway). While I'm gone, save for maybe a few quarters tossed over my shoulder on the way, I'm not there contributing. In fact, most of the time I confess I don't contribute out of disgust with what they're doing.

In years past, I was lured into giving by the broadcast of a few great Jeremy Brett's Sherlock Holmes portrayals, a marathon run of Fawlty Towers, the promise of a mug embellished with PBS Mystery, Masterpiece Theatre or The MacNeal-Lehrer Newshour.

Fund-raisers used to be a time where the local PBS station's personnel made a connection with the local populace. Now it's all robotic broadcasts done by paid, D-rank speakers and actors nobody knows.

There must be an audience for the utter rubbish PBS puts on now, but it clearly isn't the people who watch PBS. I can imagine that someone unaware, for PBS fund-raisers aren't publicized, discovers this programming, likes it, contributes his bit resolving to adopt PBS only to find a few days later that PBS doesn't continue to broadcast this sort of thing. Which means that the next time this person sees it, he simply keeps on surfing.

Randomly firing smoke detectors

This has been happening to me. I don't mean the beep every couple of minutes indicating the need for battery replacement, but the whole (linked) system going off. I did some research and found some interesting points that likely explain my problem.

How do smoke detectors work?

There is a source of beta particle radiation (yes, smoke detectors are weakly radioactive) that continually releases particles across a small space to be picked up by a detector. As soon as the stream of particles or even part of the stream is interrupted, the alarm goes off.

Systems that meet modern codes are interconnected both to 120v power and also linked by an additional electrical wire such that when once detector finds reason to go off, every detector in the system goes off in sympathy. This results in a whole house protection that is very effective.

Even though a modern smoke-detection system is wired to sector current and powered by it, each detector has a back-up battery much as radio alarm clocks and other devices for the "convenience" that this provides during power outages. The convenience of this in the case of a smoke detector is simply that if the power's off or out and your house begins to burn, one or more detectors will presumably sense it and sound the alarm.

What can set off smoke detectors?

1. Low battery.
2. Condensation.
3. Change in temperature, especially from warm to cold, probably because of condensation.
4. Cooking smoke or vapors.
5. Dust particles.
6. Tiny insects and arachnids.*

* This appears to have been my case because of the randomness of occurrence coupled with the random length, but short duration of the alarm. My guess is that the vibration of the alarm is annoying enough to chase the little beasties out of the hole in the detector sensor mechanism.

Is it possible to diagnose the exact cause?

If the alarm duration permits it, running around examining each detector will reveal, for most brands, that the offending detector is showing a red LED light instead of the usual, continual green one. This is the detector causing the rest to fire off.

When should I change smoke detector batteries?

Other than the obvious need to do this when the detector begins to complain by beeping every few minutes, many advise spending an hour each New Year's Day or the evening before your locale goes on or off Daylight Savings Time. Detector batteries usually last a good year making this a good policy.

I personally do not replace the batteries until I hear the detector beep. I find that my batteries are lasting several years.

Do smoke detectors go bad?

Yes. However, people frequently replace them unnecessarily with new ones after 1) a family member or acquaintance experiences a catastrophic fire, 2) unexplained failure creates mistrust. Still, better safe than sorry.

Why is the need to replace batteries only detected at night?

This probably lies in the realm of urban lore. No one seems to know why, but it is widely reported. Many also report that it drives them nuts while other inhabitants of the household seem to be able to sleep through the beeping.

Page numbers in electronic media

Despite what I said recently to my mother about there being no page number handling in Kindle, there is a Menu function on Kindle, Go to Page, that suggests that if you know the paperspace number of a book's page, you can get there. This has very obvious limited utility and I've never done it.

It's just that while you're reading, you don't see page numbers and to figure out what page you're on is probably (I think completely) impossible. All you have is the percent indication of how far you are through the text. I have two Kindles myself and when I synchronize the one to the web, then pick up the other and synchronize to the last page read, it doesn't say what page or anything.

Perhaps we'll lose our "page number centricity" in favor of percent as electronic media becomes more widespread and dominant.

(Does this not establish "chapter and verse" as a superior system of organization for books? Perhaps that's a little too stuffy for novels, eh?)

An aside...

For instance, I noticed that the precursor indications that Asher (in My Name Is Asher Lev, one of the greatest English novels ever written that I've just read for the third time) would paint the three-way conflict between his mother, father and himself came more overtly predicted at 73%, 80% and 87%. I'll forget these numbers within a few days, I'm sure. Why was I watching for this? Because the dénouement at the end of this book is one of the most poignant in literature.

Even further aside...

And, I'm back in paperspace now as I can't justify spending money on a book for Kindle I already own in paper. Thus I'm reading (again after having read it 20 years ago when it appeared) the sequel The Gift of Asher Lev. I've had a couple of paper copies of My Name..., but the last copy I had, I loaned to someone in a hospital who, when I later attempted to retrieve it, clearly had the impression that I'd given it to him so, I made no issue of it.

Back to the farm...

If you think a lack of page numbers is somehow hampering, imaging reading Atlas Shrugged which is 1200 pages. On the other hand, maybe I read it (last spring) precisely because on the Kindle, I had no idea it was anywhere near that long (although I totally knew it was on the same order as War and Peace which can be in excess of 1400 pages).

Now, I can see that this post has completely deviated from the original subject. Could that be for any other reason than that there's precious little more important than reading? Music and literature: nothing can dethrone these which reign supreme over leisure (and beyond). 

Test first, code later...

Another day, more proof that the first stroke of your finger in vim or whatever your favorite editor is, should begin with public class ...Test.

I prove this to myself altogether too often.

Whatever, I've never been on a project, even one with which I have so much to do as the present, for which there are myriad tests missing almost from day one.

Today, I went to tackle some "clean-up tasks" postulated in a distant sprint planning as something we'd need to get around to. Circumstances made it so that I needed to pitch in to help an area that's not ordinarily mine. So, I immediately set about adding tests for the little details I figured a couple of months back might need particular attention.

As the French say, Ben, voyons ! And how! Handling of nearly every one of the little details was either absent or seriously compromised. The test bits, which I wrote in JUnit using Mockito to eliminate any connection to wire, database or stuff that would defeat total automatization, were tiny, but they did the trick. In the space of probably two hours, I had the tests written and the implementation fixed.

For this, I can only thank my old friends from Brisbane, Dean Povey and David Leonard, for teaching me the maxim that is the title of this post. I'm only a deacon in this church of writing tests first, coding afterward, but I hope to become an ordained priest before much longer.

Patriotism in an era of repression

When I think, as I often do, about what distinguishes modern Americans from those who were willing to take up arms in defense of their personal and political liberties all those generations ago, I don't see many parallels remaining.

Two major distinctions exist in my mind.

First, it's not an us-them sort of thing. I realize that many colonists saw themselves as English subjects, but it's obvious that the British parliament's and King's unfeeling arrogance alienated enough thinking people to spark a nascent nation (no pleonasm intended here, but...). And, you had to be a thinking, indeed radical person for the most part even to find yourself in colonial America in the first place.

It's hard to raise up opposition against tyranny when the tyrants are you.

Second, today so many just aren't citizens anymore.

I think a couple of hundred years of assumptions largely fulfilled along with a Zeitgeist of democracy people have bought into whereby nations are becoming increasingly democratic (not sure this is even really, deeply true, but it's a different debate) have put Americans to sleep about what it means to be a citizen and the real threat that any government at all poses to liberty. In short, people assume that governments are legitimate to the point that individual freedoms are purely secondary considerations. Worse still, Americans now believe as long have their French counterparts, that it's government and not Nature or God that grants rights and liberty.

Immigrating peoples, especially Hispanics, come from a backdrop of appalling political servitude and a Crô Magnon-era understanding of themselves in the face of government, and do not expect liberty in the way our Founding Fathers thought both natural and crucial. I mean no slight: many immigrants come here for economic prosperity and personal safety for their families. I'm down with that as a totally honorable reason to come. Our distant ancestors, however, came because to stay home would have meant death or at least sore persecution for their religious beliefs. Those are reasons for creating an America of the Declaration of Independence, the Constitution and the Bill of Rights.

In summary, I don't see America irrigating the roots of the tree of Liberty with its citizens' blood ever again. Instead, what I see coming is strife and bloodshed unassociated with the lofty goal of "putting things aright" in a proper revolution.
