After having used my pair of Polk Audio RTi8 paired with Onkyo 606 reciever for close to 3 months, I decided to re-calibrate Audissey thingie. When I did it before, I did not bother to put the calibration microphone on a tripod, although I immediately recognized the purpose of a hole at the bottom of the mic assembly. Instead I (imagine that!!!) held it in my hand. The result of the calibration

Obsessing over absent-minded person would be strange. Admiring person with either short- or long-term memory loss would be difficult. Emerging artificial intelligence, however, is encouraged to be "forgetful" for the purpose of being resilient in the face of feeble networked silicone fabric it is destined to dwell in.Well-balanced systems combine caches of all levels.

I had a bunch of photographs from my 2006 trip that I wanted a panorama made of. Finally found some time. I used one of less sophisticate tools available, one that came with my Canon camera. Then I had trouble trying to find software that would let me print this big photograph over a sequence of pages that I would be able to glue together.Solution was pretty counterintuitive. I used Nero Digital

If you are like me, stuck with Java 5 for one reason or the other, you may be having difficulty determining how much heap to allocate to a process, and whether the ratio of young generation space should be different from default. A shortcut can be taken if your primary goal is maximum throughput. We know about HotSpot ergonomics, but with Java 5 it takes too long for it to work its magic. HotSpot

I was entertaining this idea for a while: to carry an OS of choice in my pocket, on a bootable Flash drive. Yesterday I decided to treat me to this geeky pleasure of unwrapping new hardware (8GB PNY Attache USB 2.0), downloading an ISO (Ubuntu 6.4 Live CD), and burning it onto a CD. The guide at http://www.pendrivelinux.com/, found it easy to follow and it "just worked" in the end. Open Office

That's the same one that killed one hard drive already... this just sucks. I was expecting for the thing to serve more than 4 years. The symptoms I have, think I tracked it down to that small board that sits below power button and row of "One-touch" buttons. It's really a flimsy piece of equipment, and either there's a crack in the board, or the bunch of wires does not connect reliably. So the

Few days ago hard drive in the HP notebook used by our kid had died. I heard its last cries, but I did not understand what it meant. I decided to perform the usual maintenance, went upstairs and turned the PC on. Strange rattling noises followed, but PC still booted, and I was able to perform the usual set of tasks: cleaning up temp files, checking for virii and spyware, defragmenting space.

And so it came to pass: I, too, encountered adversity of enhanced bytecode :) It was puzzling to get a finger on it, as the only exception I've seen was a java.io.EOFException that would be thrown in the client. So, the stream of data was suddenly interrupted by the server. But server would give no explanation why... So until I attached debugger to server process and tried to inspect the values

Can find no other word to describe this. In short, installing Vista screwed up my Windows XP installation. In detail, imagine reinstalling Windows XP 3 times (not counting attempts to repair strtup by means of both setup CD for XP and setup DVD for Vista...) and reinstalling Vista once in a span of one evening. Win XP was occupying first partition of first IDE hard drive. When Vista installed

Java integration needs some work: when Java Settings application is launched (this one is AWT-based, innit?), Vista disables some of its eye-candy.My fears are dispelled: OpenGL is very much supported on Vista (at least by NVidia) as is demonstrated here by running JOGL demo application that uses, among other things, programmable shaders. More curiously, 3D applications like this Java-to-OpenGL

Transparent window borders are extremely prettyThis one was designed to drive you mad: overprotective is seemingly synonymous to secure as far as Microsoft is concerned. Every non-trivial action results in this warning banner... infuriating.While Java Runtime is being installed, NVidia drivers download.

Next day, at 1:20 p.m., installation begins. No option to upgrade a 32-bit version of Windows XP is offered.This is where I'd like Vista to reside: in the same partition with Win XP 32. After all, Windows 95 coexisted with Windows 3.11Bad assumption :) Windows Vista (Beta) prefers to decimate the older cousin (am I using the word appropriately?)Well, crap, I have to cut another 20GB slice of the

In upgrade mode, installation will try to download updates. That should be helpful to many users, given device driver readiness. Looks like I've exhausted the easy options... On to prepare the drive to be repartiotioned.

Since the original hard dive has been already all consumed by the 4 OSes I have installed, I thought adding an extra HD would solve this problem. A trip to Fry's Electronincs buys me 200GB SATA for $69.90. Fine, had the drive installed (using slides I cut out of an old DVD box, as slides for drives are not available for purchase separately from storage itself. Nice one there, Sun.)So far so good.

Wow, this big word, "liveness"... A couple of weeks ago I had, again, forgotten what it means (and hope to forget again in a month, maybe). We're seeing this situation, when with increased number of requests, server's CPU usage can not exceed 1/4th of available resource (meaning, only 1 CPU out of available 4 gets pegged). Many man-days were spent trying to find the culprit. Today I just woke up

Before, it was only the NVidia driver that got ticked off by new XOrg version. But among other things that I downloaded there was an update for GNome itself. Today this thing stopped working. Crap... how am I supposed to fix it? Just try rebooting several times and pray it mends? Digging through messageboards in search of a solution does no longer sound like fun way to spend weekend.Update:

Now that my workstation is armed with 3GBs of RAM, I wanted to re-run the load test with greater number of threads allocated. This, of course, requires proportionately greater heap size, so there... I understand 64-bit JVM's stack size is quite large, thus I allowed Glassfish to use up to 2 GBs of RAM for the heap, and I instructed it to create up to 2500 threads in pool, having number of

Yesterday went to Fry's and bought a pair of DDR 3200 ECC Registered sticks of RAM 1024 MB each. 1 GB I had before in my Opteron rig felt very yesterday :) So, now I have # GB, but I was wondering about performance effects of having 2 vs 4 memory slots populated. Some documentation (on Crucial's website) made me feel for a moment that having 4 sticks has the effect of memory speeds dropping to

Since Sun Update Manager was released, I decided to join other civilized people who, either on Windows or Linux, can scroll through a list of fixes, make selection, download, have it all installed automatically and having one's system in better shape than before after a reboot (not like those neoanderthals who download patches via FTP and install them using command-line tools). It almost worked.
