What does TL;DR Really Mean?

This is the first in a series of helpful tips on Internet shorthand. Quite often, we’ll encounter an acronym and not know what it means. So, I’m here to help.

TL;DR is, at least at first glance, an abbreviation for Too Long, Didn’t Read. What it really means is that you have encountered a person with a pathological attention span; they are simultaneously saying that they have failed to bring adequate reading skills to bear, combined with the intent to cut someone down for “elitist” behavior. What elitist behavior? That of writing a literate post. Yes, really.

So when you encounter TL;DR, you can just ignore it. I put no small amount of blame upon the “sound bite” environment created by television. The erosion of the ability of much of the populace to deal with even a mildly extended presentation has closely followed television’s failure to present any such thing.

No discussion of this would be complete without a nod towards courtesy. If someone addresses an issue at length, this is an offering of information to everyone else. If you legitimately don’t have the time to read it, then the answer is not to say “you should have written a sound bite.” The answer is silence until you have read the material.

3D displays – Not here yet.

There’s been a lot of hype recently about “3D displays.” Unfortunately, that’s all it is –– hype. This is because we are a long, long way from 3D display of anything but artificially generated materials.

A 3D display actually produces a 3D representation; that is, if you change your angle of view, what you see changes accordingly. Look at the display from the side, and you see the scene from the side. Likewise, if the display is turned 180 degrees, you’d be looking at the back of the scene being displayed.

Stereo displays provide a fixed perspective generated by providing two single-angle images of a scene that are designed to replicate the angles your eyes would achieve from the (single, unchangeable) desired vantage point. Changing your angle of observation will not reveal other portions of the scene in any way, nor will moving the display.

On "The Price of Freedom"

The price of freedom is risk.

The price of safety is conformity, restriction, and repression.

You can bank on it. Our leaders certainly have.

What could go wrong?

Seriously, what could go wrong?

As the ad says, bacteria is everywhere. All kinds. And I mean all kinds. So… let’s grow a nice, healthy pile of ‘em at home, kids! After all… what could happen?

** I want you all to know that I went looking for some bacterial infection pictures to add to this post. It isn’t that I didn’t find them. Oh, no. I found them, all right, I just couldn’t bear to add them, even just as thumbnails. Some things… ugh. Just, ugh. If you want to find them, here’s the Google Search. I suggest you take along a vomit bucket. NSFA (not safe for ANYTHING)

Technology Predictions

I often read the predictions of futurists with interest; it is always enjoyable for me to consider what they have to say, why I might agree or disagree, and mentally file them away for later validation – or not.

Today, I’m going to venture a few predictions of my own, based on the state of affairs that exists in early March, 2009. The idea is to re-visit them in the years to come and see how many, if any, were close to how things actually develop.

Pixels Per Planet

In a fit of doing something that will be useful to almost no one, anywhere, I have created a calculator page that will tell you how many pixels a solar system planet, or an object of your own choosing, will consume in your final DSLR image.

In order to figure this out, you tell the calculator just a little bit about your camera, your lens system, and optionally, an object of particular interest to you.

If you actually use this thing, let me know in the comments. I suspect that I may, just possibly, get one comment. From me.

Here’s the calculator page.

…and of course, if you find any bugs, let me know.

The Ring of Truth

I’ve always had a fondness for the concise and pithy; Today, I thought I’d share some of my favorites.

  • Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all of which may be guides to an outward moral virtue, even if religion vanished; but religious superstition dismounts all these and erects an absolute monarchy in the minds of men.

    Sir Francis Bacon
