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.

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:
Download an installer and join the research!

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.

OpenOffice 1, Microsoft Office 0

Today was not a good day, computer-wise. Thankfully, the problem was with my work computer and not my home computer, even though the two are very similar in setup.

First I noticed that Excel wasn't able to use the "Save As" dialog box. I was trying to save a CSV file as an XLS file, something I do regularly. But Excel would just hang when I tried it this morning. It would also not import text files.

It was nearly lunchtime, so I mentioned it to the IT guy. He gets in the driver's seat and I go off to lunch. But first I use another computer to do the Excel job I couldn't do on my system.

After lunch, I see that he's still at it. He says it's not just Excel, but all the Office apps are messed up. And Windows Explorer Tree View doesn't expand network branches, so it's not just Office. But he doesn't know what to do about it.

We've already tried to "Repair Office" and uninstall and reinstall.

So I decide to test his theory that it's more than Office. I tried the Save As in NotePad, Adobe Acrobat 6.0 and Visual Studio 6.0. They all work. So Office is messed up, I'm sure. I don't care about Explorer -- I don't use it anyway.

But then I notice that I can't send inter-office e-mail, whereas before I could. I can receive it, but not reply. And I can't download from my ISP's POP mail servers. So whatever fix the IT tried to apply, it probably broke the mail client. Oh well -- I can live without e-mail for a short while. After all, I am part "Luddite."

But I can't even *save* a Word document, and I need to use it. So I downloaded and installed OpenOffice and easily created my "Word" document with it.

I can get by with OpenOffice only for a short time, though. I do need to create new Excel documents that contain VBA code, something I doubt can be done with OpenOffice.

As I wonder what caused this, I can only guess that it was the new scanner driver and software that I installed on Friday afternoon. Maybe if I uninstall it I might get MS Office to work again. But I'm guessing the mail client is thoroughly hosed....

Cell Phone Angst

What is it that spurs people to get a cell phone? In our case, it was separation anxiety. More precisely, it was my wife's concern over losing our daughter to School.

As the dutiful family provider, I made sure that this new vital piece of technology was in our hands and working properly before the first day of school.

And I did a great job. I had come across a great online deal from AT&T Wireless back in 2001. I ordered the phone and service sometime during Labor Day weekend and received the phone on Tuesday. I was impressed with this ... er ... impressive service.

The only problem was that AT&T didn't own any base stations in our area. Nor did they have any stores nearby. And customer service was reluctant to give us the address of the nearest base station, perhaps as a security policy. So activating the phone was tricky. Eventually, I drove through various towns until I happened to cross into home territory. When the phone finally connected, it registered itself on the network, and I was able to use it.

The phone worked extremely well in our home, and I saved lots of money on long distance by using the cell phone instead of the land line. I liked the idea of calling my wife from the supermarket to ask her whether Land-o-Lakes Swiss Cheese would be okay to substitute for Finlandia Swiss. Unfortunately, there was no signal at our daughter's school and at our church.

The phone's battery out-lasted the contract, but it did fail. Rather than buy a new phone or get an upgrade, I canceled the service and got a new plan, along with a new free phone. Even though the separation anxiety was gone, the cell phone had become indispensable, at least to my wife.

Eventually, AT&T was forced to give up its wireless service. SBC's Cingular service took over. By then our contract had already expired. But we continued with the new phone and the same service on a month-to-month basis.

By this time, my wife was using the phone as a pager for her new on-call job. She was not hesitant to point out its short-comings, the biggest of which was that she couldn't get a signal inside certain buildings. But it gave her some freedom away from home and allowed her to respond to work calls while gardening or walking the dog.

One day in May, her work place complained that when they called the cell phone, they got a message that the number was not in service. When I called Cingular, they traced the problem to a billing issue. Specifically, the credit card that they were charging to every month had expired. Rather than notify us, they did the sensible thing and shutdown the service. (That's sarcasm, BTW.) After I pointed out that they should've called us before shutting off the service (which is used to provide on-call medical service) I was told that I wouldn't need to pay the $25 reinstatement fee.

So with that behind us and the contract expired, we had only to wait for the battery to fail on this new phone. I was intrigued when Cingular (now owned by AT&T) sent us a upgrade offer. We could replace the phone and increase from 120 to 400 minutes for a one-time fee of only $19.99, probably less than the cost of a new battery. I could see the catch, though. They were hoping the new phone's additional features would cause us to use the service more. The new phone was capable of Internet access and could do IM, both of which require premium service.

It was Independence Day weekend. As I mulled this offer over, my wife's work place called our land line number to tell us that they couldn't connect to the cell phone. Instead of ringing, they would get our voice mailbox, as if the phone was turned off or out-of-range. At first I thought that maybe the voice mailbox was configured to intercept the call. But after navigating the voice mail menus, I couldn't find a problem.

Customer service remarked that there were service problems in our area. They expected that it would be cleared up within 24 hours. But in order to add our account to the list of the ones needing service, I had to give them three phone numbers that failed to ring the cell phone. Well, the work place was One. And our land line was Two. Cingular also tried (and failed) to ring the cell phone. Could they be Three? No. I was supposed to call someone right away and ask them to call me back. On a lovely summer Saturday afternoon. On Independence Day weekend.

The one person I was able to reach directly couldn't actually hear me because of all the noise at the pool. I gave Cingular the number anyway.

After twenty-four hours, the problem still was not fixed. I encouraged my wife to turn her hostility away from me and direct it instead at Cingular. They placated her by telling her it would be fixed on July 5.

On July 5, she called again. This time they explain that the problem is with the phone. It's obsolete. "How old is that thing, anyway?" they ask, oblivious of the fact that they gave it to us less than three years ago. We would need a new phone, and it just so happens that we have an upgrade offer to take advantage of. Isn't that nice? (More sarcasm.)

We complained about the coercive tactics used to get us to upgrade, which pissed off the customer service clerk and got us a reduced upgrade fee. If it were up to me, I'd've canceled the service. But my wife has been brainwashed into thinking that she cannot live without a cell phone.

The new phone, BTW, has only a few ring tones, two wallpaper images, and no free games (other than demos). Of course we're welcome to buy additional content. This is the epitome of progress -- develop new ways of getting more money from the customer.

Outlook "Signature Code" Added

Back in June of 2005, I bragged about how I spent a few hours to write Outlook VBA code that eliminates a few keystrokes. I had a request for that code a few days ago, so I decided to edit that post to add the code. This link will take you to the edited post.

I should point out that I no longer use that code. I had lost it when my work computer was upgraded, and I failed to back up the source in a reasonable location. Too lazy to re-invent the wheel, I deigned to add signatures the MS Outlook way, using Alt-I S M X Enter. Besides, after a security patch was applied, Outlook would force me to respond to a warning every time I ran that macro. And anyway, when adding the signature to replies, I would always have to move the signature from the very bottom of the message to the point just after the end of my response and before the quoted message. (I'm pretty sure I can fix that, actually.)

So the code you see in the edited post came from an hour-and-a-half session I spent to recreate the code -- a Saturday night pursuit of geeky leisure.

The Ideal Career Path

I just read Sacha Chua's "On programming as a career" post and had to stop what I was doing and write about it.

I understand the feelings that went into her post. I've been trying to strike a new career path for myself -- something with more of a human element. The thing that thrills me is computer automation, especially applied to design processes, data processing and administration. The thrill has two sources. The first is from overcoming the challenge of making the automation succeed. The second is from seeing smiles when my coworkers experience the relief that comes from knowing they don't have to repetitively point and click through several silly menus to accomplish something.

My ideal Masters Degree would be in "The Automation of Computers to Make Life Easier For the Poor People Who are Stuck Using Them."

It doesn't have to involve computers, actually. I plan to involve them in my career path only because I believe I can make more money in a field that incorporates them. I could be nearly as happy serving as an efficiency expert, helping people to live better.

Suppose someone is intent on making a fried egg for breakfast before going to work. I might suggest that she take the eggs and butter out of the refrigerator first thing in the morning. Then after she has showered and is ready to cook, the eggs aren't as cold and will cook more quickly and will be less inclined to stick. And the butter will be soft enough to spread easily.

But I've learned that not everyone likes being told how to do something. If my wife has any say in the matter, I would be better off staying out of her kitchen and woking on a computer.

How would this play out on a computer? Well, if I knew someone who enjoyed instant messaging with friends on different servers and who liked to keep up with a few RSS feeds, I might suggest they use Miranda IM, the Swiss Army Knife of IM clients. It can work with ICQ, AIM, MSN, YIM, IRC, Jabber and GoogleTalk. Plus there are numerous add-ons, one of which can make it report feed updates. And it's Open Source. The only reasons it's not today's killler app are that it lacks marketing push and it doesn't require a hardware upgrade to run it.

Anyway, good luck to Sacha, and to myself. If you have any advice for either of us, let me know!


2025-03-05 LG Fixed two broken links. BTW, the Miranda IM project was abandoned in 2018. Folks are encouraged to use Miranda-NG instead.

Net Neutrality

The US Senate is debating S 2917: Internet Freedom Preservation Act, which would prevent ISPs from giving preferential treatment to content providers that pay. They are also debating S 2686: Communications, Consumers' Choice, and Broadband Deployment Act of 2006, which would greatly reform telecommications laws and allow for a tiered Internet.

Apparently, telecom providers want to compete with cable television providers, and they want content providers to subsidize their effort. The first bill mentioned above would seek to prevent that. The second would facilitate it.

For a really well-fleshed out article on the subject, check out "Speed Bumps on the Information Highway," by Tom Abate, Chronicle Staff Writer. This FreePress page provides more arguments in favor of Net Neutrality.

I recommend this sarcastic article, called "Net Neutrality Has Ruined the Web," for those who understand something about electronic communications.

Recommended Website: Arachnoid

"Should I have an award for good websites?" I asked myself. If I did, I'd want to give the first to Paul Lutus. Eventually, I decided that giving out awards to good websites should be left to someone a lot more prestigious than myself. So I'll just humbly recommend my favorites. The first one, Arachnoid, was created by Paul Lutus.

I first came across Arachnoid when I was looking for software to perform time synchronization. I think this was way back in 1997. A quick search brought up AboutTime, which I downloaded from Arachnoid. Other interesting downloads include the web page editor Arachnophilia, and his personal finance program, PLCash, both written in Java to be useful on many different platforms. Most downloads are neither shareware or freeware. They are Careware, an idea I very much favor.

Articles abound on Arachnoid. Find out Why are computers so hard to use?. Discover Creative Problem-Solving. Read his opinions on psychology, which include a comparison of Asperger Syndrome and Narcissistic Personality Disorder. Learn more about humans from this Interview with an Extraterrestrial.

Downloads are not all you can find at Arachnoid. Check out the tutorials, which cover Calculus, HTML, C++ and even an explanation for why the night sky is dark.

What makes Arachnoid so great is the sense that its author cares a great deal about our world and its inhabitants. He works hard at making the Internet, and the world at large, a better place. Visit now!

Update on Firewalls

In my post Free Computer Security -- Firewalls, I raved about the free Sygate Personal Firewall (SPF) last year. Since then, Symantec bought Sygate. Unfortunately, this means that the free firewall product is no longer available.

I still have the old SPF install file. I could've installed it on my new computer. But using unmaintained security software is like building a fence with rotten wood and letting it fall apart.

What firewall did I install? I settled on Outpost Firewall Pro. I haven't heard many endorsements for it, but I heard no negative comments, unlike Zone Alarm. One thing about Outpost is that it is not free, although you can download it and try it for free for 30 days. The initial license fee is $39.99, and annual updates after one year is $19.99. (But if it turns out that Germany has the most shutout games in this year's World Cup, I'll get the annual updates for free. See this promotional page to understand why.)

If you're committed to using a free product, you can try Zone Alarm. You can also try Jetico Personal Firewall, which I discovered after installing Outpost. Version 1.0.1.61 of Jetico was given the Gold Award by Firewall Leak Tester on March 11, 2006, based on its ability to pass leak tests. One thing Firewall Leak Tester doesn't do is give any indication of how stable each product is.

While I'm at it, let me give you some firewall testing resources.

  • Again, there's Firewall Leak Tester, which not only publishes test results, it also offers a directory of tests that you can run on your own system. And there's plenty of advice, too.

  • The home page of Gibson Research Center, and their Shields Up test in particular.

  • Various tests on the PC Flank web site.

Amazing New Game Under Development : Spore

I read about Spore on Brad Neuberg's blog, "Coding In Paradise." This is what he posted about Spore back on April 12:
Spore is shaping up to be one of the most amazing games ever; it's like a serious work of art and science mixed together, artificial life. Check out a video.


Why can't I just quit work and volunteer as a beta tester?

Broadband Internet Access at Last!

I haven't felt this great since ... since ... since ... I don't know when. The reason is that I successfully installed DSL service on Monday. I verified the download speed to be 2.4Mbps at DSL Reports using their Speed Test. I no longer have to spend about half my online time downloading updates to all my security programs.

The service is provided by AT&T / SBC in cooperation with Yahoo. I signed up at a promotional rate of $17.99 for 1.5Mbps service for twelve months ($29.99 thereafter). The modem was free after a $45.00 mail-in rebate. Installation was a snap. The computer already had the NIC, so all I had to do was install filters on all the analog telephone devices (including the dial-up modem) and connect the modem. The most difficult part was reading the 18-page membership agreement.

I hope this means I'll have more time to post. But I suspect that I'll just goof off and get back into online gaming.

My New Computer

I bought a new computer, a Dell Dimension 3100. It came with 2.8GHz P4 processor, 1GB RAM, 80GB HD and a 17" flat panel display with 1280 x 1024 resolution. I like it.

But I was a bit surprised (in a bad way) about a few things.

First is that the hard drive is a new type: ATA serial. So the extra drive bay couldn't accept the HD from my old computer. Fortunately I was able to temporarily hook up the old drive in parallel with the CD drive long enough to copy over some documents.

The second surprise is the lack of serial / parallel ports. I had saved $30 by not buying a modem. I have three already. But when I got the new box, I knew I wasn't going to be using them. Two are external modems that connect to the serial port and one is an old internal modem on an ISA card. (The new computer has no ISA slots.)

The absence of serial ports means the mouse and keyboard are USB.

Fortunately, my printer can connect with either parallel port or USB.

I added $30 for a 3.5" floppy drive. I learned (at work) that if you don't order it installed, the case doesn't have a mounting bracket for it. :) I can't live without a floppy -- it use it to synchronize my home and work systems.

It came with Windows XP Home, which I replaced with Windows 2000 Professional after completely reformatting the drive. I'm just not ready for XP. I'll wait until a few more service packs come out. :-)

I do like the system very much, especially the display and the case, which is easy to open and work on. Overall I'm very happy with it. Now I need a new work computer!
