Ender's Game

Orson Scott Card sure is a classy guy.

Long known for his staunch advocacy against homosexuality and outright disrespect of homosexual people, and just in time for the upcoming film adaptation of his popular novel, Ender's Game, he makes a curiously timely plea to the movie-going public to put aside his views, stating in a statement to magazine Entertainment Weekly, "The gay marriage issue is moot."

How quaint, and convenient! Personally I dislike lining the coffers of such people with my dollars, however groundbreaking their works are. 

Someday, all knowledge and the fruits of people's creativity may be free. No longer will talented writers, actors, musicians, or others have to take on multiple minimum-wage jobs to make ends meet while they struggle on the side to achieve their dreams and pursue their passions. 

Instead, everyone will have their basic needs provided for so that, as Maslow indicates in his hierarchy of needs, people will be able to self-actualize and actually live rather than spend much of their daily life worrying about paying the bills, or their very survival. Not now, not in decades, perhaps not in millenia, but someday... hopefully!

I think a good first step toward such an audacious way of life is to share information.

Here, for example is a freely available set of ebooks in PDF format of the Ender's saga, which can be read online or downloaded. I encourage anyone interested in this fine piece of literature to obtain it at their leisure, without having to pay for it, and with the satisfaction that no royalties whatsoever will make it into Orson Scott Card's quite intolerant little hands.

Dell Vostro 200 Fan Noise

The Dell Vostro 200 in its mini tower/desktop case is a decent computer with just one exception.

NOISE.

When powered on, the fans shoot up to their maximum RPM for a second or so, then slow down. Depending on what you're doing the fan noise is anything from the level of relatively benign white noise to a constant or fluctuating jet engine like drone. Scanning for malware, playing a graphics-intensive game, defragmenting the hard drive, anything with lots of CPU activity prompts the Vostro 200's fans to go full speed.

I found a simple solution to this dilemma. Inside the case there are two 80mm fans for cooling the CPU. One is mounted directly atop the CPU heatsink, and the other is mounted vertically in a bracket along the right-hand side of the computer to push air out ventilation holes in the case.



I had a nice, quiet, 120mm NZXT "performance" fan lying around and decided to use it instead of the two 80mm turbofans that came with the system. 

The CPU fan atop the heatsink is clipped on with several plastic clips, I simply removed each of these with pliers and discarded them since they'd just be in the way of the wider 120mm fan. The exhaust fan alongside is screwed to the case, so I removed it likewise and discarded it.

I then removed the vast amounts of dust and dog hair that had accumulated beneath the fan. As the case is lying horizontal to the desk, I decided to loop some narrow zip ties through the fan's screw holes and through holes in the rear grille of the case. I secured the ties with enough tension to keep the fan hovering just above the plastic and metal of the heatsink assembly.

It's a mystery why Dell chose seemingly the loudest fans possible for this computer. Or, perhaps it isn't so mysterious, perhaps loudness happens to be an unfortunate side effect of cheap hardware. Or, perhaps they wanted to make it seem especially sleek and high tech by having it mimic a 747 taking off. 

Regardless, now the new 120mm fan runs at a quiet, constant speed, and keeps CPU temperatures well within normal limits, with no fear of liftoff.

Sound Card Stereo Channel Mysteriously Dies

The left channel of my Sound Blaster X-Fi Xtreme Audio sound card decided to die.





















I carefully smoothed my headset cabling in case a break had developed in the typically very fine stranded wiring of the headphones, and also tried removing the plug with an MP3 playing and noticed that only one channel was being played back, the right with the plug fully inserted, left if I just slightly unplugged it. Just in case I plugged the headphones into my laptop; perfect stereo sound, so something's definitely up with the card.  

I popped open the computer and examined the headphone jacks on the card. They appeared to be made of plain copper, and they seemed to have oxidation, much like an old penny.

I took a flat-bladed screwdriver from an eyeglass repair kit and carefully scraped away at the copper surface, revealing shiny metal underneath, then blasted away any residue with some canned air.




Now my music is once again in glorious stereo!
