Oh how sophisticated we have become in our old age. There used to be a time when just about every web page that was hip and up-to-date had a silly "hit counter" on it. It counted the number of times the page was viewed in a very simple-minded way. It didn't care about unique hosts or anything useful like that, it just incremented its count every time the page was accessed. Hit counter! Well

A fundamental error among people looking for Truth (with a big T) is to imagine that is is a nothing but a bigger version of "truth" (the little T kind). Small truths are simply things about which we agree. We say "that is true" to mean just that. "I agree with you" or, " you should agree with me" are equivalent and work everywhere "it is true" is used. Because the same word is used we take

Miscellany's previous home became suddenly unavailable. As you can see, it's back online but it is not yet completely status quo ante. Please excuse any funny behavior, or missing functionality as I scramble to restore things to normal. On a positive note, I am now using Linode and I am very pleased and impressed. Low cost, slick as a Linux-geek's forehead and cheaper than his wardrobe. I

Your IP Address Nixie tubes are a retro-technology well beloved by artsy nerds everywhere. My own memories of nixies are as the classiest digital displays, before being supplanted by the MAN-1 seven segment LED display. Today, nixie tubes are lovingly turned into clocks of very modern accuracy and even unlikely wristwatches. The nixie tube was the invention of the Haydu Brothers Laboratories

No, this blog is not dead. Some folks have even expressed concern that perhaps something has "happened" to me. Rest assured, it is nothing more than life's demands overwhelming free time. Thanks for the concern. I have several articles partially completed so look for my triumphant return soon. As a reminder, I always enjoy receiving email, and you can find a link in the sidebar.

Tools are inert. Every tool must be wielded by a person. People use tools to achieve goals. The result of wielding a tool is a product of the skill and intent of the wielder, and the suitability of the tool to the task. Consider a tree saw: it can be used to destroy a tree, to kill it, or it can be used to prune a tree, cutting away deadwood and diseased limbs to strengthen it. The way in

Now that something about 150,000 of you have visited this post, and about 19,000 of you have made links to it, perhaps I can do something to redeem all the attention paid to it. In a way loosely coupled to INSERT COIN, the campaign to save trees, through reminding people where we get paper, came to my attention. What can be better than reminding people of what they already know? I have

Today, Shlomo (our youngest, at 6), came walking stiff-legged into the room and up to my wife. Where did Igor get that brain? Shlomo:  I am acting like Frankenstein. E equals M C squared. Shoshi:   That's Einstein. Shlomo:  Oh. Sometimes Shlomo says things that leave us scratching our heads. I still don't know where he learned about E=MC².

Around here the squirrels can be a bit nutty. They get used to humans and lose much of their fear. This leads to odd behaviors. I have seen squirrels do this in the trees but never like this, on the ground.

There are hundreds of application download sites out there, but can you trust their ratings and awards? Probably not.

Lately, I have been working on a heuristic for systematic thinking that I believe is very powerful. I'd like to share it with you. Maybe you can help me refine it. For a long time I have found myself alternately embracing opposing viewpoints. At first this bothered me. It seemed to be non-committal, indecisive and not useful for decision-making. However, I have come to see it as quite

NASA has provided satellite views of the recent Southern California wildfires. These pictures bring home both the enormity and insignificance of the fires. Compared to the land mass of the US they are small spots, but the smoke they are producing is prodigious.

How many times do you stop to ties your shoes in one day? If your answer isn't "once for each time I put on my shoes" maybe you need to know about "Granny Syndrome" ("double-knotters" I am talking to you, too.) About 20 years ago I got tired of constantly retying my shoes. They would come untied a dozen or more times a day. I decided to do something about it. I set out to invent or discover

About a year ago I bought a new car. OK, new to me. She is about 13 years old now (yes, it is a she and her name is Inger). She is a 1995 850 Volvo Estate Turbo. I paid $4,800 cash for her and have her title. Inger in her favorite color, red. I think she is lovely. Her original MSRP was about $35,000. She has a full leather interior, power moon roof, CD changer, fancy climate control...

Perl makes quick programming very easy and more elaborate things possible. It is an exceptionally flexible, easy to grow into language with an outstanding group of people using it. The Perl Community is every bit as exceptional as perl itself. Even if you've never written a program, or if your programming experience is restricted to things like DOS batch, perl is something you can learn. If

I mentioned, here, that I wrote a program to put the weather on the HP 4200 in our office. The program uses the perl Geo::METAR module to parse METAR weather information from NOAA. You'll need to install the module if you don't already have it (and you probably don't). Install it using ActiveState's PPM for Windows and the CPAN program (or OS package manager) for everything else. You will

It appears that a lot of people don't have any idea how to run a perl program under Windows. Perl runs just about anywhere and Windows is no exception. The easiest way, and the way I recommend, is to download ActiveState's free Windows Perl distribution. It is very friendly with a nice installer. Once you have it installed, the program in this post will run fine. While you are at it,

PLEASE READ THIS BEFORE USING THE PROGRAM (or if you are not amused) Can this silliness be used for good? Perhaps... It is amazing how unaware some people can be. This little perl program allows you to set the "Ready Message" on HP printers to whatever you'd like. (if you want to run it under Windows, and don't know how, read this.) I wrote it after coming across the command in an HPPJL (HP

In the last quarter of the nineteenth century the Industrial Revolution had a dramatic impact on the lives of traditional artisans and craftsmen. Factories appeared turning out cheap, identical wares which aped the possessions of the rich. Fake porcelain, fake ornamental furniture and other goods made to appear posh flooded the market. The makers of traditional pottery, furniture, clothing and

The basis for the dialog was an idea that occurred to me when I was reading a few things on quantum computing. It is intentionally vague in areas, mostly it was just a fun idea. However, in a somewhat serious discussion with my friend Craig Lent, he pointed out a problem with my coin-flipping version of Penrose's variation on Schrödinger's gedankenexperiment. That is, he pointed out that Chaos

If you're right about this it's going to make global warming look like Y2K! Oh, I'm right you can count on it. Take another look in the box. One look was disturbing enough, thanks. But I still don't understand, what is it you say is happening? OK, one more time, slowly. You know that around 2005 or so, people started using quantum effects to build computing devices.

Movies are a vehicle for vicarious adventure. We love to sit for an hour or two and experience adventures through our favorite characters. Surely there's nothing wrong with that--or is there? Why should we live vicariously? Why aren't we the ones living the adventure? What is stopping you from doing what you love? Shouldn't we stop sitting around and start doing something about this?We
