Social Networks for Book Lovers

I just learned about LibraryThing from reading Sacha Chua's blog post, "Taking book notes." LibraryThing is a social network for book lovers.

The general idea is that you enter books into your library by searching for a title or ISBN. There's also an import tool that will scan a webpage and pull in the ISBNs it can recognize. I used this to import the 106 books that were referenced on my "List of Books I've Read Recently," which I might decide to replace with some references to my library on LibraryThing.

Once you have books in your library, LibraryThing will provide links to profiles of users that have many of the same books in their libraries. You can navigate to their libraries and leave comments on their profiles.

Well, that's just a brief overview. Check out LibraryThing for yourself.

For a more in-depth discussion of LibraryThing and other such sites, check out NPR's All Things Considered discussion of social networks for book lovers.

Help Our Airlines Save Fuel

Airlines are struggling with the ever-increasing cost of fuel. They've started to charge passengers to check baggage. Let's think of other ways they can stay aloft in this turbulent economy:

1. Charge passengers a fee that's proportional to the total weight of the passenger plus all his/her baggage, both carry on and checked.


2. Offer passengers stationary bicycles and other exercise machines to prevent DVT, but secretly use the machines to drive electrical generators, which can power such non-essential systems as entertainment, lighting and navigation.


3. Offer passengers free refreshments in the terminal. Lace the refreshments with laxatives and diuretics. ^{1, 2}
   

What can you do personally? Why not leave the heavy luggage behind? Just choose baggy clothing to wear at your destination, and put it all on before you leave your home. Better yet, don't even bother bringing extra clothes. Just buy your change of clothes at your destination.

With lots of creative planning, we can yet again save our beloved airline industry.

¹ Empty passengers are lighter.
² Whatever they leave behind can be used as bio-fuel.

Driving to Optimize Fuel Economy

In my area, gas prices have jumped beyond $4.00 per gallon over the last couple of weeks. I ranted before about how traffic lights contribute to decreased fuel economy. But I didn't mention that driving technique can dramatically influence fuel economy.

An extreme type of driving that maximizes fuel economy is called Hypermiling. Generally the idea is to minimize acceleration and braking. Unless you're going down a steep hill, acceleration requires more gasoline than just maintaining speed. And braking converts all your car's motion (which came from gasoline) into heat energy. So essentially, braking is like throwing away gasoline.

If this is the kind of topic that gives you goosebumps, you might be interested in the forums at CleanMPG, especially Wayne Gerdes' post "Beating the EPA - The Why’s and how to Hypermile".

And rather than boycotting gasoline for one day, folks should either not drive on that day, or at least drive more efficiently. With the subsequent drop in demand, gas prices would relax.

MySpace Notes

My pre-teen daughter already has a website and just started a blog. So I figured I should start learning more about MySpace. She's not on MySpace right now, but she might be in a few years.

I've just finished reading "Me, MySpace, and I," by Larry D. Rosen. It suggests that parents open an account on MySpace because there are many areas on the website that you can't access unless you're logged in.

Many websites require users to provide a real name and real address when you open an account. This is particularly true of commerce sites like Amazon.com. So I was not alarmed when MySpace asked for my real name and town, "so other members can search for you." It assured me that it wouldn't display my name, but I cautiously provided a bogus name, anyway.

When I finished entering the required information, it showed me the profile page that it created for me. And there was the bogus name and town displayed in nice bold type. Thanks for preserving my anonymity, MySpace.

Well, anyway, I'm there now, and no harm was done to me.

Some things from the book I thought worth mentioning. This quote, for example:

"Some MySpace young people have told me that they like to pretend to be dumb just to see what other people do and say. One guy got a date with a girl by pretending to be a "C" student and when she met him and found out he was a "brain" she canceled the date."

Autism Awareness

April is Autism Awareness Month here in USA. Would you be able to recognize the symptoms of autism if you saw them? Probably not.

The latest estimate of the prevalence of autism is that 1 in 150 people in the USA have been diagnosed with an Autism Spectrum Disorder (ASD), which is also known as Pervasive Developmental Disorder (PDD).

If you're in the fields of engineering, computer science, physics or math, the chances are even higher that you, your children, your coworkers or their children could be diagnosed with this disorder. And you should check out http://firstsigns.org/, which is dedicated to the early identification and intervention of children with developmental delays and disorders, including Autism Spectrum Disorders.

The diagnostic criteria for ASD in children concern development and ability in the areas of social interaction, communication and play. Please see "Diagnosis and Epidemiology of Autism Spectrum Disorders," by Lee Tidmarsh, MD, Fred R Volkmar, MD.

Early detection of an ASD is crucial because when interventions are tried at an early age (say at 3 to 5 years of age), they seem to be more effective than when tried later on.

Those who have an ASD and who can communicate say that they don't want to be cured; they just want to be accepted. Thus, it's not they who have the problem, it is society. Nevertheless, interventions can make things easier for children and the autistic adults they grow in to.

What kinds of interventions can reduce the symptoms of an ASD? A change in diet -- avoiding wheat and dairy productions, for example -- can help those with Leaky Gut Syndrome, which can manifest as symptoms of ASD. Another effective, diet-related approach is supplementation with mega doses of vitamin B6, or its active co-enzyme, P5P. Play therapy or Applied Behavioral Analysis (ABA) has been proven to help. In some cases, mercury detoxification may help. There are many more interventions for a parent to choose from. Then there are interventions aimed at easing the secondary symptoms that accompany ASD such as Obsessive Compulsive Disorder and Depression.

Scientists can spend entire careers looking for signs of intelligent life in the Universe. Meanwhile, medical researchers have overlooked signs of intelligence in people with autism. They assume that people who can't talk and who respond differently to stimuli must be lacking in intelligence.

If you don't believe me, consider the amazing website, Getting the Truth Out, which was originally written in response to an objectionable Autism Awareness fundraising campaign called "Getting the Word Out." Be sure to follow the presentation completely to the end.

If you suspect that you or a loved one is struggling with an ASD, visit the Online Asperger Syndrome Information & Support (OASIS). (Asperger Syndrome is an ASD, and is sometimes referred to as High-Functioning Autism.) As its name suggests, you can get a great deal of information from the site. You can find most of the support by clicking on the Message Boards menu choice and registering for the "OASIS: Asperger Syndrome Forum".

How to Avoid a Recession

There's a lot of talk about what to do about the economy. One group of economists believes that Federal Reserve Board Chair Ben Bernanke made a mistake in cutting interest rates recently. They think that will lead to inflation.

Most politicians agree that we need some form of tax cut. Some say that the middle class should get a tax break. Others say no, the middle class will just use it to pay down debt, and that businesses need tax breaks in order to hire more workers.

Some suggest that saving sub-prime mortgage borrowers from bankruptcy is the key to bringing about economic recovery.

Many of these opinions have merit, but they fail to address the cause of the faltering economy. The real problem is the rising cost of energy.

The economy depends on energy for growth. You cannot manufacture items unless you use energy. You cannot transport these manufactured goods unless you use energy. And consumers cannot afford to buy these goods if they're spending most of their disposable income on energy.

You might think we'd've learned a lesson from the oil crisis of the 1970s. But our favorite energy source still seems to be based on oil. And as the oil supply tightens, our economy falters.

Imagine this scenario: It's the distant future, and our world is without oil. Where does our energy come from for manufacturing, transportation and consumer use? Solar and nuclear.

Equatorial countries are the world's energy movers and shakers. They get the most intense solar radiation. They produce the most electricity per photo-voltaic cell. Their biofuel is the richest and most abundant on the planet.

So perhaps it's time to cut taxes on oil, gasoline and electricity. Maybe it's even time to think about subsidizing energy costs? It depends on how serious our government is about maintaining economic growth.

Engineers Week

Engineers Week was last week. One reason the organizers put effort into making and promoting Engineers Week is to get kids interested in engineering. So why does it take place during winter vacation week?

So I'll be belatedly "celebrating" Engineers Week this week by visiting my daughter's elementary school class and talking about electricity. My presentation is titled, "Watt is Electricity?" Get it?

I made a little electromagnet kit for each student. All I did was wind about four feet of solid 22 gauge copper wire around a nail. I placed this in a bag with a D battery, some paper clips and a sheet of paper with this text:

Electromagnet Test Kit
Contains:

• 4’ 22 AWG Solid Insulated Copper Wire
• Steel Nail
• D Battery (1.5V)
• Paperclips (to test electromagnet)
  

When electrical current flows through a wire, a magnetic field develops around the wire. By winding the wire into a tight coil around an iron core, the magnetic flux is concentrated, and the magnetic attraction is strong.

Touch the bare wire ends to the battery terminals.

Watch Out – it gets HOT.

How many paper clips can you pick up?

What do you think would happen if:

• You unwrapped some of the wire?
• You used a 9V or 12V battery?
• You wrapped the wire around a pencil?

More on Traffic Lights

I was too tired to continue my previous post. So I'll add some comments here in a new post.

I wrote:

If the number of cars on the main road is so great that you need to interrupt the flow in order to let yet more cars on it, you're contributing to yet more traffic congestion.

Actually, about 16 years ago, traffic lights were introduced on entrance ramps to the Long Island Expressway. The idea was to prevent cars from entering the highway during rush hour. That demonstrates an appropriate use of traffic lights -- to improve the flow of traffic rather than to impede it.

I wrote:

It's inefficient to force several cars to stop for the sake of one or two cars that are already stopped. Forcing a car to stop and then accelerate back up to cruising speed is a significant waste of gas. In fact every time a driver applies the brake, he or she "throws away" the fuel that was used to accelerate the car. And acceleration is what uses the most fuel.

And...

Many of these intersections are so small that when cars turn onto them from the main road, the cars trigger the Hall effect sensor that causes the light to cycle. Thus, the light turns red for those who navigate the main road even when there's no car to yield to! More waste!

You can solve both problems simply by installing (or moving) the sensors farther back from the intersection and decreasing the sensitivity. That way the light won't cycle unless there are a few cars queued up. It might be a good idea to change the mode to blinking red-yellow during non-peak hours to allow cars to enter the main roadway whenever it's clear, but then have the light switch to give the right-of-way to the smaller roadway when enough cars are waiting.

I can imagine the day when every intersection will have a traffic light. Hopefully I'll be dead by then. Or perhaps traffic lights will be part of a Intelligent Vehicle System that's designed to route traffic for maximum efficiency. Lights will be used to tell motorists when it's safe to enter the intersection rather than stop other cars to allow them to enter.

The Problem With Traffic Lights

"'See, I can time them perfectly,' the [traffic] light said with satisfaction. 'I get hundreds of them each day. No one gets through my intersection without paying his tax in gas and rubber.'"

"'Go blow a bulb!' the car growled at the light.

"'Go soak your horn!' the light flashed back."

- from pages 187 to 188 of "Centaur Aisle," by Piers Anthony

I've had this quote in my "Quote du Jour" for several weeks, ready for the day I finally rant about traffic lights.

In my town, traffic lights are installed indiscriminately as a feeble response to town growth. The rich folks flock to buy McMansions in new developments. Then they complain that they can't get onto the main road without waiting a minute or two for a break in the traffic. So up goes yet another traffic light.

There are intersections where traffic lights are needed, such where two main highways intersect.

But why install one at a "T" intersection on a busy main road for a tiny side street? Here's why it's not a good idea:

• If the number of cars on the main road is so great that you need to interrupt the flow in order to let yet more cars on it, you're contributing to yet more traffic congestion.
• It's inefficient to force several cars to stop for the sake of one or two cars that are already stopped. Forcing a car to stop and then accelerate back up to cruising speed is a significant waste of gas. In fact every time a driver applies the brake, he or she "throws away" the fuel that was used to accelerate the car. And acceleration is what uses the most fuel.
• Many of these intersections are so small that when cars turn onto them from the main road, the cars trigger the Hall effect sensor that causes the light to cycle. Thus, the light turns red for those who navigate the main road even when there's no car to yield to! More waste!
• Finally, traffic lights waste electrical power all day and night. In fact, they remain powered up even in the wee hours of the morning when no one needs them. At night they're so bright you could read a large-print book under them. Why not reduce the light intensity after dark and save money? True, some lights are set to blink red-yellow, and thus they require half the electricity to light the lamps. But the controllers that run them also waste electricity. So just shut them down completely and get that power consumption down to zero. Drivers know anyway to stop before they enter a main road in the absence of traffic control.

Anniversary Dates for Engineers

When an engineer picks a wedding date, chances are it has some numeric meaning. It's a fun challenge to come up with a sequence of numbers that forms a date that falls on a weekend. And afterwards, it lessens the likelihood that the anniversary will be forgotten.

Here are some simple weekend dates in MM/DD/YY format that are based on simple multiplication facts: 02/16/08, 12/08/96.

Here are dates based on sequences: 06/07/08, 05/10/15, 09/16/xx. With that last one, the month and day are so good, we'll ignore the year.

Some other nice dates: 08/16/08, 03/14/15, which are the first five digits of Pi.

Are you an engineer that married? What date did you choose?

Emacs: Yet Another Cool High-Tech Thing

Two years ago, I wrote about Servant Salamander. In that post, I described how Servant Salamander substituted nicely for Norton Commander when I made the switch from MS-DOS to Windows NT.

The other software substitute I made was to replace my favorite text editor, Brief. When I started using Brief, it was by a company called "Underware." When I stopped using it, it had been taken over by Borland. They had no plans to make it Windows-compatible.

I loved Brief's ability to record and playback keyboard macros. It had undo. Its regular expression search and replace capability was powerful. It could cut and paste columns of text. It could be scripted. It supported multiple windows.

I continued to use Brief on Windows NT, even though its cut and paste didn't work with the Windows clipboard. And I recall having display problems at certain video resolutions.

So I set off in search of a new Windows text editor. The minimum requirements were:

• Column marking, cutting, pasting.
• Undo.
• Regular expression search / replace.
• Keystroke macros.
• Windows compatible.
  

I wanted an editor that could be scripted. And even better, one with the same keystrokes as Brief, or with a reconfigurable keyboard.

I came across Crisp, Zeus and then Vedit a bit later.

I rejected Crisp almost immediately, even though it seemed to be the ideal replacement. The problem was that it was unstable. Or, more accurately, it made my computer unstable. So I dropped it quickly.

I was mostly happy with Zeus. But sometimes I needed to edit binary files, and one thing I did not like was that Zeus could not handle null characters. (And it wasn't 100% Brief-compatible.) That's why I got Vedit. Vedit did a great job with all kinds of files of all sizes. I was even able to edit EBCDIC files, which helped when I was writing an EBCDIC to ASCII translator. But I never got comfortable with Vedit, so I continued to use Zeus primarily.

One day I decided to try another search for the Ultimate Text Editor. Someone recommended Gnu Emacs.

Emacs was "sort of" Brief compatible. In fact, it was Crisp-compatible with its Crisp-mode Lisp add-on. But in reviewing Emacs, I came across the advice that it's best to learn the native key-mapping. So that's what I did, back in 2001.

It was a bit hard to get used Emacs, and I did have to remap the keyboard a tiny bit. For example, back then, Emacs would interpret the Del key as Backspace, which deletes the previous character instead of the next character. (This is not true of more recent versions.) Also, I stumbled over Emacs terminology. For example, it's not "Cut" and "Paste" but rather "Kill" and "Yank."

But all the effort I put in to it was well worth it. Now, I don't bother to write text-manipulation programs because it's easier (and more fun) to script Emacs to perform that kind of work. I enjoy using Emacs Planner to keep track of tasks and notes that pertain to numerous work projects. And at one time, I enjoyed using the newsreader Gnus with it's wonderful ability to score message threads based on any number of regular expression filters I could come up with.

Emacs is licensed under the GNU General Public License, which means that it's free, not only in the sense that you can obtain it without cost, but also that you are free to modify and distribute the software, provided you pass along this same freedom.

Emacs is amazing. It is constantly being improved by intelligent people who demand great things from their programs. It can run on many different platforms. Try it out!

The Personable Computer

We call them Personal Computers. But why can't they be Personable?

The other day I was typing an e-mail. I thought I had on-the-fly spell checking enabled. Then I typed the word "triennial" and didn't see the red squiggly underline. I wondered, "Did I really spell that right?" and "Is spell check really turned on?" I decided to run the spell check manually. And it ran, finishing with a disappointing absence of fanfare over my correctly spelled word.

Why couldn't it respond, "Hey, great job at spelling triennial, big guy"? I am an engineer, after all, so I'm supposedly disposed toward bad spelling.

How should that response have worked, exactly, without actually being annoying? Certainly a focus-stealing pop-up would've been downright annoying. And a little checkmark after the word might not have been effusive¹ enough. Perhaps a message in the status bar would've afforded the best trade-off between noticeability² and interference.

The reason computers don't provide this kind of feedback is because of how intensely users loathed Clippy, the default Microsoft Office 97 help mascot. Clippy was best known for saying, "It looks like you're typing a letter. Would you like some help with that?"³ Of course users loathed that. We know how to type a freaking letter. We don't appreciate being patronized by something with half the intelligence of an earthworm. Whoever designed that hadn't ever held a door open for a feminist.

But if Clippy had offered praise instead of assistance (or perhaps in addition to assistance), he/it might've been accepted or at least tolerated. And it would've been better if it weren't so dorky looking.

I'm sure we'll see a return of something like Clippy, albeit well-disguised. It's just too tempting a feature to ignore for long.

---

¹I spelled this correctly the first time, too!

²But alas, I did not spell this correctly the first time.

³And there are wonderful parodies⁴ of this too, such as, "It looks like you're typing a suicide note. Would you like some help with that? Okay, first tell me, how do you plan to kill yourself? Choose one: Gunshot to the Head; Slash Wrists; Overdose; Jump Off Tall Building or Bridge; Step In front of a Moving Train, Truck or Automobile. Great! Thanks! Next, tell me the reason why you're killing yourself: No One Understands Me; My Lover Left Me; I'm Broke; I Can't Stand This Asinine Clippy... And so on.

⁴See, for example, One Egg Shy's Clippy's Guide to Suicide Notes, or his Clippy’s Guide to Ransom Notes.

Hey buddy, can you spare a few CPU cycles?

Do you leave your computer running and connected to the Internet? If so, why not donate its idle CPU cycles to scientific research? You could help figure out the cause of Alzheimer's disease, predict climate, or search for evidence of gravitational waves or extraterrestrial intelligence.

The Folding@Home distributed computing project is committed to exploring protein folding. Its goal is to gain an understanding of:

• Alzheimer's Disease
• Cancer
• Huntington's Disease
• Osteogenesis Imperfecta
• Parkinson's Disease
• Ribosome & antibiotics

All it takes to get started is to download and run a small program. Click here for more details. Other protein research projects include Rosetta@home and Predictor@home.

Other things your computer could work on:

• CPDN: climate prediction.
• SETI@home: the search for extraterrestrial intelligence.
• Einstein@Home: find spinning neutron stars.

The True Meaning of Christmas

It finally clicked in me -- the True Meaning of Christmas.

It was when I heard the Christmas story retold for the fourteenth consecutive time, at last night's Family Christmas Eve service, at our local church. The Pastor had read Luke's Gospel, and then he expounded on it.

He started by describing Luke 2:1-7 in more detail. The reason that Jesus, Mary and Joseph were staying in a stable is that there was no room at the inn. That I've known since I was a child, but nothing more.

The rest of it needs to be appreciated against a backdrop of adult experiences. The child I was did not bother to wonder why they needed to find an inn.

The Pastor explained that Joseph needed to haul himself (and the pregnant woman he was engaged to) 80 miles, by foot, from his home in Nazareth back to Bethlehem in order to be counted in the census. So he could be taxed.

That's my wife and me, Joseph and Mary. Not only do we have to undertake some pain-in-the-ass journey for some poorly-planned government bullshit, we have to do it when we're about to give birth. All for the ultimate pleasure of paying taxes. This is jury duty on a Grand Scale.

To make the story more interesting, Joseph is caring for a woman whose child she carries is not even his.

And this is the way the Universe works. Even God's Children cannot escape suffering the idiocy that this world has to offer.

Time Magazine Person of the Year (What Else?)

As soon as I heard that Time Magazine's Person of the Year (POTY) was "Me," I knew I had another sarcastic blog entry to write. By now, this entry is but one of many that pokes fun at Time. And if you want to listen to great commentary on the topic, redirect your browser to today's commentary by Bill Langworthy on NPR's All Things Considered.

I'd rather not waste much content on Time. POTY noise actually rewards Time in the end, even if it's criticism. I just want to point out that choosing me as POTY (along with hundreds of thousands MySpace teenagers who are either horny or lonely or both) was plain laziness. If Time had done a little research, they'd've discovered the term blogosphere, which might've led them to this special issue of Communications of the ACM. And somewhere in this two-year-old, well-researched set of papers would be the person or team responsible for creating the technology that enables us POTY winners to blog.

If it sounds like I'm angry at Time, it's because I am. Aren't I supposed to receive some monetary award? Because I didn't. Hello?

Build My Own Universe? Are you Joking?

Okay, I finally accept that my elementary-school-aged daughter can design her own web page and probably make it look a whole lot nicer than this site. But could the next generation one day build its own universe?

Incredibly, some physicists think so, according to this feature on NPR's All Things Considered:

http://www.npr.org/templates/story/story.php?storyId=6545246

This is a cool page, not just for the feature article, but for the related links. The one bit of disappointment I feel is that I wish this came out nearer to April Fool's Day. That way I could fool people into thinking that something is a joke when, in fact, it's actually real.

So I wonder if our Universe was once created by a team of ambitious physicists in a higher level universe? What if they have to shut down their experiment due to lack of funding? Or what happens if a student overheats a Twinkie and in the process accidentally destroys the lab while attempting to redo one of the Twinkie Experiments?

Recommended Website: Pandora

When I was a kid, my favorite thing was to buy a new record from the music store and play it on my home stereo for the first time. Discovering new songs, or hearing played-out songs anew, was magic to me.

So I was thrilled when I found out about Pandora. (Thanks, Tirsden!) This site helps you find music you like. You give it the names of a few of your favorite songs, and it creates a playlist of similar songs. As you rate the suggestions, the resulting "Radio Station" starts to provide you with fresh, enjoyable music.

Curious to know what kind of music I'm into? Check out Hard to Pin Down Classical / Progressive Folk Rock Radio. Some of Pandora's choices are pretty cool. Others are quite a stretch, although it's usually fun to hear them. I guess I can sense some similarity between Blue Oyster Cult and Renaissance. And I had no idea Todd Rundgren jammed like that (The Ikon).

Edited on 2006-10-11 to add this list of Radio Stations...

1. B-52's Radio
2. Funky Electric Bass Radio
3. Hard to Pin Down Classical / Progressive Folk Rock Radio

Promoting the Field of Engineering

The website TryEngineering.org touts itself as a resource that should help pre-college students decide whether engineering is good career choice for them.

The link that immediately caught my eye was Engineering Life Profiles. The target page is titled "Life of an Engineer," and it sports a list of links to the job descriptions / professional biographies of seven practicing engineers.

As an eletrical engineer, I was curious to read the profile of Carl Allison (Electrical Engineer).

Mr. Allison is employed by Walt Disney Imagineering, which is hardly a typical destination for an average engineering graduate. I'm glad that he's happily employed producing things that entertain people. Unfortunately, many engineers wind up in a cubicle dungeon, spending days just poring over one parts list after another in order to identify and replace pure tin-leaded components with components that have leads plated with palladium silver. And this is for some space hardware hardly anyone will ever see. There are engineers that spend their entire careers studying the long-term reliablilty of resistors, or think of ways to reduce the cost of an assembly by a few cents.

If you're a pre-college student who thinks engineering might be a good career, make sure you talk to a few engineers first. Don't just read glitzy promotional websites and think that's how your life will be. Try to shadow a few real engineers during the summer before your final year of high school. Although the summer camps that TryEngineering has listed are probably too oriented to having fun, they're probably better than nothing. They at least help you determine whether you have the aptitude for cool design and problem-solving aspect of engineering.

The Highs and Lows of Being a Luddite Geek

It isn't easy being both a Luddite and a Geek. Each encounter with new technology evokes a Dr. Jeckyll / Mr. Hyde response. Sometimes it's quite strong, like the day my new, computer-controlled boiler was installed.

The old boiler was installed when the house was built, about 1950. It still was heating water very well, but over the last few winters, it wasn't maintaining pressure. And a few weeks ago, it started to leak intermittently from the circulating pump.

Here's how both the Luddite and the Geek in me responded to the new boiler.

Luddite:

So the guys took out the 60-year-old furnace yesterday. It was still delivering steaming hot water, as it had always done faithfully (except for the times that the igniter and transformer had to be replaced).

They put this new, computer-controlled thing in its place. After it's all connected, filled with water and pressurized, they flip the switch, and guess what. Nothing. The burner doesn't fire up. Nada. Zilch.

The guy tinkered with it for three hours, until 7:30pm actually, and then said the piece of crap module was bad.

My wife was especially upset. Not only did she not have hot water last night and this morning, her formerly-white kitchen floor is filthy, the light beige carpet on the stairs and landing is smudged with greasy, sooty footprints, and our daughter has a cold and needs a nice, steaming bath.

What on Earth compelled me to buy a boiler with a computer in it? All it has to do is switch two relays on and off -- one for the burner and one for the circulating pump. How hard can it be? I can't believe I spent more on this than my car.

If you ever want to ruin a good, reliable piece of equipment, add a computer to it.

Geek:

Things didn't go too well yesterday, that's for sure. Well, the owner came today. He couldn't believe there was anything wrong with the computer. So he tinkered with it for a while. When he realized he wasn't getting anywhere, he tried to jury-rig it to bypass the computer controller. Fortunately his helper noticed something peculiar about one of the jumpers on the controller. It was not connected! Bingo. Connect it up, it fires right up, and we have burning hot water.

[days go by...]
Over the past few days, I got to go through the manuals that came with this feat of engineering. I navigated the menus and chose one of the week-long day / night programs and altered it to our family's schedule. This will ensure that our boiler won't turn on at night during "summer mode" when it's not needed. And in "winter mode," it will govern at what times the temperature setback should kick in / out.

With its temperature sensors for outdoor and indoor air, plus knowing what the room setpoint temperature is, it's able to taper the boiler temperature as the room temperature reaches the setpoint. It follows one of a few pre-programmed heating curves that adjust based on the outside temperature. And the outdoor temperature sensor can be used to switch the unit between its summer and winter modes. The temperature at which it makes the switch also is programmable.

It delivers hot tap water the same way it heats the house. As the water in the tank reaches the setpoint (which, of course is user-adjustable) the boiler can shut down since it has enough remaining heat to finish heating the water.

I tried lowering the hot water setting to 125F, but I noticed that the dishwasher's heating element was coming on. So I set it back up to 130F (where the installer had left it) to keep the dishwasher's electricity use down.

The first time I took a shower, I was really impressed. It's just like at the health club. No more turning the faucet toward the hot position as the shower progresses. I set it, and it stays. Wow. And forget about turning off the heat ten minutes before taking a shower. The computer will give priority to heating tap water over heating the radiators.

You want to know a secret? I paid more for this boiler than my car. But it's worth it. I'm not queer or anything, but I really want to invite my buddies over for a shower.
