My Christmas Present (Early) - The Celestron 44340 LCD Digital Microscope


Nothing says "Merry Christmas" to a geek like a new piece of technology. Here is mine, a Celestron LCD digital microscope. (Or is it digital LCD microscope? Oh, whatever.) I've already taken several images with it, including the ubiquitous "let me image my hair follicle". That to people who work with microscopes is analogous to the "Hello, World!" program that all new programmers compile and run.
How is this new microscope? In a word, cool! I love the images it takes, which it will do at 1600x1200 without going to the (always crappy) digital interpolation. It takes really good videos, too, which is nice if you need to be able to look at a particular object at several depths. As always, the depth of field of this scope is poor, but that's physics, not poor design or bad engineering. It came with 5 slides, which is not even close to being enough. I've already gone through all five. I'm now working my way through, well, any object that will fit under the lens. And being the engineer that I am, I've already got a list of improvements I'd like to see incorporated.

1) Add an option to delay the taking of the picture. This is a must-have. Right now, when you take a picture, the scope, while well made, moves ever so slightly. I'm having a helluva time taking clear images because the scope is still moving when the image is snapped. I'd prefer a short delay to allow me to push the button, let the scope stabilize again, then have it take the image.

2) It provides the option to put the date on the image. I'd prefer a metadata field that provides the magnification of the image, the color lens being used for setting the light color, and the type of lighting (underneath, above, or both).

3) Make the image capture remotely controllable. Yes, I realize this will take some more work. I want the ability to plug in the USB cord and be able to take the images from the computer. Hit a "Snap" button in a window, it takes the image and instantly transfers it to the computer. That solves the shaking problem AND the transfer problem all in one.

4) Make the codes for talking to the scope over USB open source. You want to get some buzz going for your scope? Do this and you'll have programmers the world over snapping up scopes left and right. They'll hack the living crap outta your scope and have it doing things you never thought possible. And you'll sell a boatload of scopes, to boot. So, why not? Oh, and you'd be able to ignore all of my suggestions because the hackers will do it for you!

Merry Christmas all!

The "Ghost Radio" Web Site

Ever heard of EVP? It stands for "electronic voice phenomena". I'd never heard of it until today, when I happened to read a story on the JREF web site asking for comments on a Youtube video. This particular video (from a Brit based on his accent) claimed to show EVP. And what, pray tell, is EVP? Allegedly, it's the "voices" that radios make when they are not tuned to an actual signal. People are claiming that the radios are actually producing real, honest-to-God voices.
And like all things that anyone believes, there's even a web site for it. Except, in this case, it's not just a web site. Oh, no. For something of this vast, cosmological importance, we need an association. And not just any association. The American Association of Electronic Voice Phenomena.
On the very first page of their web site, they make the following claim:
People report experiences such as hauntings events or EVP, and these experiences can be verified and often replicated as objective events.

What?!?! Really!?!? You're out and out making the claim that "these experiences can be verified and often replicated as objective events"? Really?!?! So, tell me this: On what are you making these claims? What's your criteria? In what type of settings are you doing the experiments? What's your test group and what's your control group? How are you controlling for bias in the tests? You are performing multiple tests, aren't you? Not just one with a couple of your friends over for ... whatever? And why isn't this evidence openly available on your web site? Why isn't it presented so that outsiders (or disbelievers, such as myself) and check your claims?
Here's a test that I would want to try: Make a recording of what you believe to be EVP. Then I would want to play it back to 20 people (just for a start) and see if they hear anything. If so, what? If they all agree that they're hearing the exact, same thing, then we go to the next stage. Oh, and when you make the recording, I'd want to control for outside disturbances. I'd want the radio to (a) be tuned to nothing at all and (b) not scanning. Let's control for outside disturbances, shall we?
P.T. Barnum, even though he didn't actually say it, was still right.

Why I want the score to read, "Col Barfoot: 1, HOA: 0"

In case you've not heard about it, Col Van Barfoot, a recipient of the Congressional Medal of Honor, has been told by his homeowners association to take down his flagpole that he uses to fly his American flag. Due to his age, the fact that he's a veteran of three wars (WWII, Korea and Vietnam), and (probably most importantly) a Medal of Honor winner, this has caused quite a stir.
I support Col Barfoot in this. First, I hate HOA's. I've read all of the comments about how they keep home prices up. But I've not heard anyone provide any evidence of that. To me, they are simply an artifice cooked up to "keep out the undesirables". Since when were we willing to sell out our liberty for some unspecified "Your house price will stay high" crap?
Second, as someone who (unfortunately) lives in an area that has an HOA, I'd ask this of all of the people who state, "He agreed to the HOA rules when he bought that house." My question is this, "How carefully did you read your covenants before you bought?" Of the two houses I've owned, both had HOAs. The covenants are legalese guacamole. They are designed by lawyers for lawyers. Did his explicitly state, "No poles in the front yard?" I'm willing to bet it didn't. I'm further willing to be he asked about the flag pole before erecting it because the covenants did not explicitly cover poles in the front yard.
Third, and to me most important, he earned the Medal of Honor. He gets a pass. Period. Considering that the majority of MoH awards are given posthumously, that takes some doing. I've had an argument with one person who blew that off by saying, "That was over 40 years ago." To which my response is that does not matter. He earned a frickin' MoH. He gets a pass. Forever. Period.
Fourth, the flagpole issue is not a violation of a law. At most, it's a violation of a contract. That means that he cannot be arrested. The police will not be coming to his house.
Finally, don't bother with all of the "what if" games. Those are the people who say, "What if he decides to paint his house purple?" or "What if he decides to put a car up on blocks in his front yard?" or "What if he decides to fly the Confederate flag instead?" He didn't. He put up a nice flag pole to fly an American flag, and he more than earned that right. End of discussion.

Reason #4 Why I Like Open-Source: Rhythmbox Fixed in 2 Days

I discovered a bug in Rhythmbox, which is the music-sorting and playing software on Ubuntu Linux. If you look at the link, I posted the problem on Sunday, the 22nd. Here it is 2 days later, and the problem is fixed. Now, the patch has not yet been posted, but I'm willing to bet that it is well and truly fixed. Why? Because I think the Rhythmbox maintainers had an idea where the problem was as soon as I posted it. It only took a couple of back-and-forth posts to figure out where the problem was. I was even able to test one of the maintainers' hypothesis myself. From there, I was able to post the results of my research back, and away they went.

One of the things that I most loved about this was that they showed me how I, a real newbie in programming and Linux, could capture the data they needed. They then provided me some feedback, asking me more detailed questions, showing me some mistakes I made in collecting the data (very patiently pointed it out, I might add), and continuing to work with me. That was my blinking light. That gave me a sense that something was happening. If the big software companies would take a hint from this, they might learn something.

Then again, maybe not.

Paranoia... Will Destroy Ya!

Found this in the review section of a Firefox add-on called "Ghostery". The comment was titled, "You can't get around tracking." It starts off well enough. (All bold-faced emphasis is mine.)

I implement tracking analytics so I can develop more user friendly sites. I have also implemented non-invasive adds in order to keep content free. By blocking my scripts, you are only preventing developers like me from creating a better (and free) experience for users like you. Most tracking data is anonymous anyways. Unless you click a link from an email, no one can tell your personal browsing habits. This plug-in is a security blanket for paranoid "the government is watching" people.

Okay. So far, so good. Logical. Rational. Seems like a person who's concerned that all of this ad-blocking and cookie-blocking, while well intended, may be having bad repercussions. Let's continue.

Just so you know, the government tracks every single page request in the US. There is no browser setting or plug in that can prevent this.

(Sound of a car careening off the cliff...) WTF?!?! Went from "Hey, I just want to make a living" to the fastest Dr Jekyll / Mr Hyde, instant-right-turn-into-the-Twilight-Zone switch I've ever seen. I have Michael Oldfield's seminal work playing in my head right now. Where's my garlic and hot-cross buns? But, hey, he's not satisfied with simply making a right turn off the cliff, he wants to go down in a blazing fireball. Let's read his spectacular finish.

Much the same way to preventing unwanted pregnancy is abstinance... same goes for tracking... you must stop using the internet if you don't want anybody to know what you are doing. Otherwise, watch your back... 'cause we're going to GET YOU!! hahahahahahahah

I didn't realize that the medication could wear off so fast. I'm wondering if there's a straitjacket missing its wearer right now. Regardless, I'm going to be giggling about this one for quite some time, after I install just about every ad-blocking, cookie-cutting add-on I can put in my browser.

It's the Money, Stupid

The BBC reports that the captain of a pirate-hijacked ship has died of wounds suffered when the ship was seized. Near the end of the report, the article adds:

The upsurge in piracy in the region is a consequence of the failure to find a solution to Somalia's political disputes, our correspondent adds.


No, you idiot. It has to do with something your article said earlier. But since you appear to have severe short-term memory failure, let me refresh your memory.

The pirates earlier told reporters they were leaving the ship after being promised a ransom of $3.5m (£2.1m), although there was no government confirmation of this.


Can you say, "Cha-CHING"? The pirates can. That, my friends, is what's driving them.

Any questions?

Need a Calculator for School? Try this!


I was reading through ticalc.org's web site and, especially, the update on the DMCA situation vis a vie TI's threat to sue Brandon Wilson because he dared to crack the encryption key TI uses to lock down the software in its top-o-the-line calculator, the TI-83+. Yup. That's right. It's a whoppin' 100 smackaroos to get you one of those babies. Perfectly understandable that they'd be upset.

Okay. Not really.

I was reading through the comments on their news site concerning this issue when I found this one explanation as to why TI is pissed (er, that means unhappy in this context, in case any one of my UK or Australian / New Zealand colleagues is reading this... doubtful... this web site gets less hits the the Chicago Cubs.) Anyway, here's his explanation:

Their latest reaction is baffling at first, but the reasoning is perfectly obvious if you understand who their customers are. Schools, CollegeBoard, ACT, Kaplan Inc, and other institutes have been hostile toward the whole 3rd-party OS issue for years. Now that calcs are a blank slate for anything we can cook up, TI must show their partners they won't take the situation laying down--even if it's a lost cause. Either way, this will be the stall tactic until new deals are made, or some kind anti-hacking revision rolls out. This line of reasoning may sound alien and incomprehensible from a coder's standpoint, but I witness it on a daily basis in the business world.

So, if this the problem, if schools and colleges are well and truly against 3rd-party operating systems, well, then, I have the cure. The picture says it all.

Any questions?

An Open Letter to Texas Instruments

Dear Dumbshits,

Back in the day, you built a truly wonderful computer. I know because I had one. I also had the expansion box that weighed as much as the USS Missouri. And I still have the 300 baud modem that you built for it. Now, you're left with your IC market and some calculators. Me, I prefer my HP50g, but some of the calculators you make are pretty good. Given that you do not dominate the market in handheld calculators, you'd expect that any news, or "buzz" as the current phrase goes, that generates publicity for your calculator would be a good thing.

I guess you didn't get that memo.

Seems a hacker has managed to crack the encryption key for one of your calculators. And you're pissed about it. Sent him a high-falutin' memo stating, "Stop that!" Threw in some big words and acronyms, including DMCA.

I guess you just. Don't. Get. It.

You have a group of people who are dedicated to tinkering with your calculator. Are they trying to reverse engineer your hardware so that they can make their own? No. Are they selling the software that they have managed to reverse engineer? No. But because you are currently suffering from some cranial-rectal inversion, you're going to be the guy with the truly smelly flatulence who just arrived at the tea party. And instead of saying, "Hey, we've got a lot of people who are looking at our calculators as cool! Let's build up some buzz! Have a conference! Start a contest for looking at some other part of the calculator!", you decide to kill the party just as soon as it starts.

Are you REALLY this stupid?!?! Can't you SEE the possibilities here!?!? So they cracked the encryption key of your vaunted $100 calculator. And somehow you think this is going to impede on your corporate profits. Ya know, it might. But something tells me that, if you saw this as a potential to improve the market share, to increase awareness (People thinking, "TI still makes calculators? Hey, I thought they quit after that TI 2500 Datamath thingee."), to really and truly hype your calculators, you'd be on the right track. Are you following me here? Can you see where I'm going with this?

That's right. Park your lawyers in the closet for a few minutes and figure the possibilities. Lots of buzz, lots of hype, lots of publicity, lots of free advertising. For YOUR calculator. You know, the one you want to sell more of? Hellooooooo?!?! And all you have to do is to say, "Ya know, perhaps we should concentrate on the hardware and not so much on the software. Perhaps we can even make it open source. If we do that, there's this whole community of open source people out there. Perhaps they'll want to buy our hardware. And by default we can control that." (knock-knock. Anyone home?)

Please. Consider what I'm saying. You can either stay on this same road. Or you can really and truly make a comeback in the calculator department by embracing a different mindset. The choice is yours.

Back in Business

After reformatting the Linux partition and starting from scratch, my system is now up to Ubuntu version 9.10. Yes, it's pretty nice. The interface is different, but I'm not certain that alone made it worth it. I do know that the Ubuntu team has stated that there were many changes that made the upgrade worthwhile. I'll take them at their word. I've discovered that some things that didn't work before do now. For example, I have an old webcam. It didn't work at all before, but does now. Kind of. Another thing is that this new version is recognizing my other partitions without me prompting them. I'm now in the process of reloading my data and putting back the various programs that I need. Skype is back (which was one thing I really needed) and so is Octave. I'm hoping to get the latest version of Freemat (version 4.0) installed as well. I've got Thunderbird back, and all of my e-mail is back in its proper place. All in all, the upgrade was disastrous, but the OS, once installed properly, is working fine.

The one thing I'm doing better this time than with the original install is keeping careful notes of what is getting installed and how I installed it. Some of those notes will be written up in upcoming articles.

A Big Setback

Today, I received a notice from Ubuntu that a major upgrade was ready. Specifically, the system was ready to upgrade from version 9.04 (called "Jaunty Jackalope") to version 9.10 (called "Karmic Koala"). Being the trusting type, I hit the "Upgrade" button. As the upgrade progressed, I received a few errors, namely that "OpenOffice" was running. I managed to kill the processes, though for some reason it kept coming back. Anyway, there wasn't anything that said, "This is a MAJOR error! ABORT! ABORT! ABORT!" Two hours later, it finished. I restarted the computer and thought, "Hey! Looks great!" Wanted to go on about my business. Just before the upgrade finished, I was listening to some music. So I wanted to continue listening.

Only problem is my sound wasn't working. And still isn't working. Also, every time I reboot my computer, the icons on my desktop all shift back to the left side of the screen. (I have certain ones that I explicitly put on the right side of the screen.) And sometimes Skype doesn't start up. And also when I reboot or shutdown, I get a pop-up window that says an "unknown" process is still running.

Suffice to say, I'm far less than thrilled. I went to the Ubuntu forums and found someone else with a similar problem on the sound. He managed to get his problem resolved. I didn't. That was topped by someone called "lovinglinux" who came on and told me tersely that I was on the wrong thread. It was a kubuntu thread, and I was ubuntu. Despite the fact that the original creator of the thread was actually helping me. At the time, I was thinking, "Well, bite me, "lovinglinux", you arrogant, kubuntu prick!" I've calmed down since then and realized he was trying to save me from possibly getting bad information. But as mad as I was at the time, he was "wrong thing to say at the wrong time".

I've scoured the internet (both Ubuntu forums and non-Ubuntu ones) hoping, praying to find a fix. Somewhere. Somehow. And I've come up empty. Seems that a LOT of people are having similar issues. I'm now backing up all of my data on Ubuntu because. I. Am. Going. To. Have. To. Start. Over.

No, waiting is not an option. I need sound NOW. I need Skype to work reliably NOW. I need the sound because I use it with Skype. And I need both of them NOW. So, as I'm typing this, I have data backup in progress. Once it's finished, I'm going to start over with a fresh install, which seems to work better for most people. Still, this will be 6+ hours out of my life, not to mention the future time to re-install much of the software I've come to rely on. Freemat & Octave. Google Earth. Wireshark. Wine. Crossloop on Wine. Paint Shop Pro on Wine. And the list goes on. And this is time that I could have been spending doing real work.

Does this mean I'm dissuaded from Linux? Hardly. But if you're considering making the switch, wait a few more weeks.
