Overloaded

The past month and a half has been a blur of obligations, medical issues, and no energy to do much else so the blog has been neglected. No promises on increasing the frequencies of posting can be made until life gives me a few breaks. The Cubs could use some breaks right now too, as I type they are down 3-0 to the Yankees and it is the top of the first inning.

Like the baseball team is experiencing, it feels like life is hitting doubles against me. 5-0 now, the Bronx Bombers are clobbering starter Anderson.

Dealing with Dad’s health problems has been most of the drain though that will be letting up for awhile now that he’s successfully undergone multiple procedures to stretch his pyloric valve. Along with a change to Nexium (insurance hates that so the co-pay is large), his heartburn and reflux have vanished. Now to see if he can tolerate solid food again.

It Sounded Good at the Time

Oh gosh, it has been far too long between posts, yet I don’t feel guilty about it this time. Too many things have been going on in too many parts of my life so something had to give… and this wasn’t the only thing.

Multiple rounds of illness involving whatever upper respiratory virus of the moment circulating amongst the local population robbed me of days then weeks. Sudden developments with Dad’s paralyzed stomach suddenly showing motility led to a highly irritating pair of fiascoes last week added to the woes. Even the weather decided to take a turn for the worst after flirting with Spring like temperatures.

My sole consolation during the past month or so has been getting into audio theory and execution more deeply. Curiosity about crossovers, frequency charts, and clearance drivers has led to a lot of mad scientist behavior on my part not always wisely executed (see multiple rounds of illness above).

Fortunately, end results have been promising with stunning increases in performance for my newly rigged up 5.1 setup in my bedroom to make the PC much more of a hifi platform. It all started with a lucky win on eBay luring me down the rabbit hole.

2017 and I’m Still Catching Up

While intentions to post were good, I failed to get anything written during the past month and a half. A great deal has happened that while not being earth shaking has been time consuming.

A few of the events in reverse chronological order:

I just purchased a new keyboard, a Motospeed Inflictor CK-104, to deal with perpetual cat hair and crumb problems. Being one of the newer mechanical keyboards with backlighting it has far easier access under the keys for cleaning. Double shot keycaps and nice Outemu blue switches made it a steal at $44 at Amazon.

So far I’ve only gamed on it without any serious typing. Writing this post is its baptism by fire…

Modifications

I find myself in the middle of December of 2016 wondering where the year went. Of course much of the elapsed time was spent being ill, yet there was even more weirdness eating up precious seconds, hours, and days. Included in the strangeness are the subcategories of politics, sports, technology, things breaking down, and celestial events. Just how many super moons can one year have?

This is starting to read like a year end post and I’m not willing to concede 2016 just yet. In the spirit of losing time…

Great Video on CG in Modern Movies

I have been known to complain about poor computer generated special effects in movies and also films that seem to exist only to bombard the audience with artificial imagery, so this video was of great interest during my browsing the Net today. Particularly fascinating is the usage of CG for things we don't even notice -- watch the whole thing. It may change your viewpoint. The final analysis is something I agree with and bless Rocket Jump for including Ray Harryhausen's work at the end.

Snow and Other Discomforts

A short guide to configuring a LG 27MP33HQ monitor for a better picture follows after an account of how I ended up having to do so. Not what I was planning to write, but what else is new?

Yesterday morning greeted the residents of rural Yucatan with a small accumulation of snow. As I type this, more of the white stuff is falling leaving the yard a patchwork of green and white. Winter has shown up early in Southeastern Minnesota and shows no signs of letting go in the immediate future if the forecasts are to be believed.

That wasn’t the only sight to rudely greet me yesterday. Turning on my computer monitor revealed waves of green rolling through the right side of the screen. Having seen this before, I knew it was hardware failure. Still, doing all the right things to eliminate software driver and cable issues were undertaken to no avail. In fact, the not terribly old Asus VH236H decided to get worse by the minute.

Knowing Is Better than Not Knowing

Time for an update on what is going on with my father’s battle with cancer. With the last chemotherapy infusion cancelled at his request, the hope had been that it would accelerate the schedule for surgery to do something about in improperly functioning stomach. That hope has been dashed as of today.

Results from the barium study indicate that there no longer is an obstruction of the exit from the stomach. However, the flow is still not much and it appears that nerve damage has been caused by the RCHOP regime. The upshot of this is that Dad will probably never eat food again.

A longshot attempt to increase motility in his system will be tried for a week by increasing Regulin, a drug he was already on for side effects. When that fails, a permanent feeding tube will have to be surgically implanted into his small intestine. More information will be provided by the PET scan next week and decisions will have to be made afterword.

BBS Memories

After reading an article at Ars Technica reminiscing about calling dial up bulletin boards with a 2400 baud modem, I’ve been trying to remember details of those days. Twenty years of the Web have erased most of those memories to my disappointment. Even remembering names of the BBSs I frequented escapes me.

What I do remember is mainly concentrating my attentions on an OS/2 board near the end of my long distance calling days. At that point, America Online had become my main destination and so the primitive ANSI based boards were on the way out, not only for me but for most users. I wish I could remember the board’s name that has slipped so easily from my personal memory banks.

A Frightening Innovation in Malware?

It may be Halloween and a time for spooky tales from the dark recesses of the imagination, but real life has more than enough frightening things. As we are now a high technology bound society in the West, it seems some of the more alarming things involve computers. A new strain of malware has shown up that supposedly can use a computer's speakers and microphone to transmit data.

If this turns out to be a legitimate thing rather than a hoax, badBIOS is a thing of nightmares for IT and security experts. Normally I'd call this a fraud or someone having a paranoid break, but the technology has existed  in the world of espionage for decades that allowed lasers bounced off of windows to measure and detect conversation inside rooms, for instance. This would be the kind of project a government would be capable of in theory, most likely one of the big three: the United States, Russia, and China.

It's been awhile since I've seen a BIOS based attack get any press, so this caught my attention quickly. Of course simple precautions will prevent malware from getting on your system and this one is said to have come in on a USB thumb drive. However, the way this thing works is fascinating if real.

Part of me wants this to be a hoax, because this kind of PC infection would be incredibly difficult to deal with if it spread widely. Another part of me wants it to be real simply because it would be an amazing feat of computer science. But most of me is holding judgement until more evidence is brought forward.

UPDATED 6 Nov 2013:

While there is a possibility this is a real virus or trojan, the evidence isn't checking out and some are calling into question the mental stability of Dragos Ruiu. Strange behavior by him in social media is making it look like a paranoid episode, which is still bad news of a different kind. Given the fragmentation of BIOS implementations, it would be extremely difficult to pull off with limitations to attacking specific brands and models of PC's.

And So It Goes

Life hasn't returned to normal at the Boonedocks, but it is getting closer to what passes for it. My father continues to recover and after seeing the accident scene along with hearing first hand accounts it is obvious he shouldn't have survived. Yet he's up and about, having even attempted a repair call Friday.

I'm behind on things thanks to the events, a screamingly bad back, and little things coming up. Hopefully this week will be different, however it is already looking oddball. As soon as I finish the review of Whisper of the Heart I'm working on, I'll have to move directly into the scary movie theme for Halloween. One rewrite and one new review are all I'm guaranteeing.

Meanwhile, the leaves are turning colors, the winds have cooled, and summer is over without having made much of an appearance. It has simply been a disappointing year in regards to weather and quite a few other things. Good thing that I expected it to be an off year for that has ameliorated the disappointment.

At some point I should do a couple of posts on the two sets of headphones I've recently gotten. One goal for the week is tearing apart the larger Superlux 681 cans to solder in a corrective filter made by chaining resistors and filters. Practice with spare parts will happen first, since I'm a novice at soldering.

Then there are the amazing Noontech Zoro HD portable headphones. No corrective filter needed there, they are simply superb with a neutral bias like studio monitors. I should re-cable them though. For awhile the built in condenser microphone worked with an adapter for PC usage, but then it went into constant static. While it doesn't affect the sound I hear, it makes me wonder about the long term survivability of the cord.

Anyway, I need to get some screen captures for the next review!

A Sound Decision

Little did I know that I’d end up with some quality headphones within a few days after my last post. Research had led me to AKG’s K 240 being the best performer for my auditory tastes while not spending hundreds of dollars. However, I kept digging due to a feeling I hadn’t considered every option. Wandering about the audiophile side of the Net I ran into something that was too good to be true: under $50 headphones that rivaled $150-1500 cans. But the more I dug into the phones it became clear this wasn’t a come on or mass delusion. UPDATED 8-29, see below the fold.

Enter the Superlux HD681’s which I purchased for just under $32 U.S. from Amazon.

These are full size circumaural (enclose the entire ear) headphones with a phenomenal range of 10-30,000 Hz. Nobody wears these to impress anyone for they are the cheapest looking plastic affairs I’ve ever seen. Muted red plastic trim adds to the dullness of appearance.

Fortunately, they are anything but dull in sound. Absolutely amazing range with deep yet controlled, bass, sparkling mid-tones, and extreme highs. The latter can be too much depending on the kind of music played and many will probably want to use an equalizer to tone down the high frequencies.

A Ripping Good Time

An adventure into audio featuring:

• Sound! (an Asus Xonar DSX)
• Action! (CD ripping)
• Thrills! (swapping an op-amp with an OPA2111KP)
• Wildlife! (Media Monkey)
• And a cast of thousands! (my music collection)

When opportunity knocks, you are obliged to take it up on its offer, no matter how dangerous it may be. That’s living life on the bleeding edge of technology and it isn’t for everyone. But for the daring there are rewards to be had, oh yes.

So when the onboard audio of my new motherboard didn’t impress me with its decidedly unmellifluous tones, it left me looking for a new conduit to pump my eight thousand odd music tracks through. It had to have good clarity and not cost over a hundred bucks.

Building a Better Beast

I mentioned awhile back that I’d built a new computer and would write more about it. Now that the origin of the post is dispensed with, on to the actual content! It is going to be long – consider yourself warned. This post is for the casual tech geeks out there and won’t be as in-depth as individual reviews would be. However, it will still be a bit much for those not technically inclined.

The titular beast with all the main components installed before the first power on. It’s a mess before cable rerouting was done. These days it is slightly less messy.

Going for the Hat Trick

I said I wouldn’t build or buy a new computer until it was possible to get three times the performance of my upgraded old warhorse. Opportunity came knocking and initial results are in…

Benchmarks were not done under perfectly clean circumstances because I wanted something closer to real world performance reflected. Dropbox and other utilities were running at the time. Also, the EVGA GeForce GTX 670 actually performs better now once I found the hardware fan settings were too low. Setting a new software profile changed its performance a great deal so it would be a full five stars now.

Benchmarks increased by the following multipliers:

• Passmark Rating 3.57
• CPU Mark 2.95
• 2D Graphics Mark 2.11
• 3D Graphics Mark 2.56
• Memory Mark 3.74
• Disk Mark 8.27

The focus was on CPU and memory speed rather than gaming benches since I consider myself a power user foremost. Video and image editing is incredibly fast now. Games are through the roof, of course, but less impressive than the multitasking boost.

I’ll post more about the build down the road a bit.

An Excellent Video on Film Aspect Ratios

Perusing Blue’s News this morning I ran into a link to a must see video on why movies are shaped like they are. Ever wonder why older movies are almost square shaped and newer ones are elongated rectangles? Wonder no more, The Changing Shape of Cinema explains all.

In my reviews, I always detail what aspect ration the DVD or Blu-ray content is in since the ratios vary greatly. While I was aware of some of the history, this video answers the important questions of when and why different formats were created. It also explains why HDTV’s are a different shape than older television sets.

I have to go on record as loving widescreen and used to watch all my DVD’s in tiny letterbox mode on the old 4:3 27” TV. Getting a 40” HDTV as a gift made me a very happy camper and did justice rendering the glories of cinematography.

Go watch the video!

Summer Has Arrived

Hot and humid weather has at last arrived in southeast Minnesota. Hopefully it will help the late planted crops, but a lot of farmers in area valleys accepted crop insurance payouts rather than plant. At least the corn is visible and we'll see if it can get to "knee high by the 4th of July."

It's been a long week due to my health. Allergies, wet weather aggravating my back, and problems sleeping combined to keep me at low ebb. I probably had a cold or other bug on top of all that to make things annoying. Yesterday was the first day I was up to doing anything real and grocery shopping took that out of me. I swear it wasn't sticker shock -- there were actually some bargains.

Real versus CGI Special Effects

Over at BoingBoing I ran into this great post and discussion on old school special effects and what's been lost in changing over to CGI. The starting off point is Ray Harryhausen's wonderful work and things go from there. Rarely are comment threads worth reading on big sites, but this one has a lot of valid points being made.

Personally, I think CGI can be fantastic when used properly and devastating to the suspension of disbelief when poor. Part of that comes from accepting the unreal aspects of older stop motion or miniatures effects for what they are when we visually process them. So when something that is photorealistic doesn't move or behave correctly, the mind freaks out disproportionately. That's the Achilles heel of CGI and I just had that experience watching the trailer to The Hobbit: The Desolation of Smaug:

It looked pretty good until the scene with the elves in the trees chasing the dwarves in the barrels. Right there the fluidity did not match the rest of the image and jarred me out of full immersion. Quick cuts of real stuntmen would have worked much better, but the temptation of CGI leads to directors using it too much. And this is the work of one of the better CGI directors out there, Peter Jackson.

Motion capture is one way to ameliorate the effect, but so far nothing has completely fooled my eye in a movie. So I'm back to learning to forgive the limitations and hope my eyes eventually do too.

Technobabble: Video Card Style

There is nothing quite as infuriating as troubleshooting personal computer issues and it can reach exponential heights when nobody else has successfully solved it. That’s the situation I’ve been in for the past month since getting a Nvidia Geforce 650 TI based video card. Part of the pain was making the mistake of testing the 320.xx beta drivers, which ended up being certified in 320.18 without correcting any of their bugs. Check out this forum for multiple threads on the issues involved.

Some of the bugs are show stoppers. By that, I mean they lock up the computer which truly qualifies as a stopper. The worst symptom is that of Windows Explorer locking up while allowing currently running programs to function. They can be used or shut down, but Ctrl-Alt-Del doesn’t work, launching programs fails, and you can’t shutdown. Other folks have had their video cards actually burned out by the drivers.

So I’ve spent the last week or so uninstalling and installing drivers (use safe mode, folks – you’ll be grateful you did) to find something remotely stable. 310.70 was fantastically unstable, 306.97 was slow in games, and 314.22 showed some of the same lockups. I’ve settled on the latter for now, since they crash the least.

Checking the latency on my PC with LatencyMon reveals large problems with Nvidia’s driver kernel, nvlddmkm.sys. I’ve disabled powering down the video when the PC is idle and that’s helped stability. So far I’ve kept the PC going for its longest stretch by enabling the screen saver to make sure the card doesn’t go dormant.

Digging for solutions exposed another large issue and that was what was causing Mass Effect 2 and 3 to fail to run. It turns out that starting with Windows 7 the power management in the operating systems from Microsoft park the cores in multicore CPUs. This saves power for laptops, but is pointless for desktops. A utility called parkcontrol made all the difference in the world in allowing the games to run.

The big surprise from using that was how much faster and responsive the PC has become at doing everything else. From Internet browsing to graphics editing, everything is much faster now. Why this is an issue with Nvidia and not with AMD Radeon video cards is a mystery to me.

If I had things to do over again I would buy an AMD Radeon 7790 based card. The Gigabyte 650 TI hardware is excellent and never spiked in heat like some with the 320 drivers, which is a testament to its cooling system. But I never had driver issues with Radeons like this.

Nook HD to Get Google Play!

This is very good news for owners of Nook HD and Nook HD+ tablets. Barnes & Noble is not doing well and there was talk of spinning the Nook off from the main company if a buyer could be found. That would have meant being locked into their software and content store which could go under at any moment.

Instead the full Google App experience is going to come to the Nook HD:

Faster Web Browsing with Chrome: As Web browsing continues to be among the most popular tablet activities, NOOK HD and NOOK HD+ now feature the Chrome browser for fast start up and page loading and an unlimited number of tabs open at once. Customers can even sync bookmarks across any device with Chrome.

Google Search^™, Gmail^™, YouTube^™ and Google Maps^™: Customers will have instant access to Google Search, Gmail, YouTube and Google Maps, now built in to NOOK HD or NOOK HD+. Sync calendars across multiple devices and check email from any account including Exchange, Yahoo! and Hotmail.

This will be rather nice since it will all work with the built in user interface, which I like but cannot use in my semi-hacked Nook HD. Apex Launcher has been installed to allow access to my non B&N apps. I’ve actually been using Google Play since early January and for the most part it has worked well. One thing that I hope is improved is compatibility checks with apps. Some don’t understand that the Nook HD is more than powerful enough to run them.

I use my Nook HD everyday and love the thing. Fast, light, and a beautiful screen in a 7” format have made it my perfect tablet for reading, research, and Sunday school teaching. Have I mentioned I love the thing?

Defeat and Victory

If there is one thing that can be said about high technology is that when it works it is like magic and when it doesn’t it feels like a curse – or cursing. So I’ve been dealing with an ugly side effect of upgrading to the GeForce 650 TI this week. Every game I’ve thrown at it has run faster and looked prettier with two exceptions. They would be Mass Effect 2 and Mass Effect 3.

Neither will run. The best I can get out of them is a slideshow after the intro movies. Neither can connect with EA’s servers and the moment 3D graphics are used they run about 1 frame every 2-5 seconds.

Normally I can solve such a problem on my own or by browsing gaming forums. Not this time. Every trick and tweak known has been tried including:

• Reinstalling the games.
• Installing Nvidia’s latest beta driver.
• Reinstalling DirectX 9.0c.
• Reinstalling PhysX.
• Setting processor affinity via task manager.
• Setting processor affinity via a utility.
• Running windowed.
• Running with the resolution low and all the pretty settings at lowest.
• Glaring balefully in the direction of the games.
• Deleting save games and imported settings from previous installments.

My suspicions lean toward bad PhysX coding in the game, but from all the complaints online about something having changed for the worst in recent months one has to wonder.

What’s really ironic is the more temperamental first Mass Effect runs beautifully. Of course it is on Steam…

I give up. It is rare to be defeated this way and it is very disappointing. Time to remove the games from my drive and gain a huge amount of space back since I have all the DLCs.

Some of the aggression I felt after that went into tearing my PC apart to install an intake fan Gateway never bothered to. It involved snipping rivets (and using a Dremel on two) to remove rails for hard drives plus unplugging just about everything that could be unplugged. Nearly three hours of fighting and fuming later the new fan is working nicely.

The air flow has always been suspect in the case and now it should be just dandy. Now to test how gaming temps go, though the cold front threatening snow make it a little harder to verify.
