Throwing AMD Bulldozer A Bone
AMD - Bulldozer or Bobcat?
So the reviews are in, and it’s not a pretty picture. AMD Bulldozer has hit the street and reviews across the board show the new flagship CPU from AMD barely keeping pace with Intel’s “consumer tier” i5-2500k in performance benchmarks, while having the high end Intel i7 line of processors stomp it is almost every benchmark.
Tom’s Hardware had a retrospective on the AMD Bulldozer release and poised the question, “Did we expect too much from AMD Bulldozer?”. The writer takes the position that AMD marketing set expectations too high for performance and competitiveness in the marketplace by stunts such as the Guinness World Record for a processor hitting 8.4Ghz overclock.
So is it all doom and gloom for AMD? Can nothing positive come from the release of the AMD Bulldozer architecture? In this blog, my goal is to outline a couple important points we should all take from AMD Bulldozer and perhaps a give silver lining to the clouds currently gathering above AMD.
Why the idea of FPGA Bitcoin Mining is stupid
Posted by eric in Bitcoin, Hardware, Miscellaneous, Opinion on August 23, 2011
SKYNET BITCOIN MINER: ONLINE
Field Programmable Gate Arrays (FPGA) have been around for quite some time now and have seen wide deployment as a middle ground between utilizing an existing platform (ARM comes to mind) or investing to have a custom ASIC created. Since Bitcoin Mining has boomed, there has been whispers of a fabled “great FPGA grid” that was going to ruin the Mining marketplace and dominate the Bitcoin economy.
The problem is that FPGA’s are terribly inefficient. Let me explain why, then let you all in on a little secret.

On the subject of Bitcoin and creating free Money
The All-MIghty Bitcoin (BTC)
I don’t want this blog entry to be about explaining Bitcoin (BTC), so I’ll point you folks looking for more information over to Wikipedia where they have a very in-depth article on the topic. What I will talk about in this post is a story of my involvement in the whole Bitcoin shenanigans that are happening on the net and where I think I’ll go with, or leave it.
In early June of this year I caught wind of Bitcoin really taking off through a friend who had started experimenting with solo mining using his CPU. At the time, I had thought nothing much of it and brushed it off as just another distributed project along the lines of SETI@Home or Folding@Home.
Over the course of a week or two, through bloggers and twitter feeds the whispers in the wind of Bitcoin had turned into a full on fog horn! Bitcoin was a modern day gold rush and if you weren’t in on it, you were missing out! The numbers at the time were ridiculous and it sounded like you’d be stupid not to get in on it. Earnings for miners being upwards of $2000 per month, people investing thousands of dollars in new hardware and obviously the news media coverage of the less glamorous use of Bitcoin… that of the drug trade through the Silk Road.
I didn’t want to be the last person to the party, so I jumped in.

Google TV — Another stop in my quest to find my Home Theater Unicorn
Posted by eric in Hardware, Multimedia, Reviews on February 21, 2011
As I’ve mentioned in previous posts, I’ve been using a home theater PC/Media player in one form or another over the last couple years to stream videos off my network to my home theater.
Devices I’ve used at length:
- HTPC running Windows Media Center
- Western Digital TV Live!
Both of those devices were OK, but I felt that both had their limitations. Either lacking in features or usability. Both required use of their own inputs on my home theater and thus, were not very well integrated into the whole experience. Issues such as occasionally having to plug in a keyboard to the HTPC to address an issue, or the Western Digital TV Live not having certain features, like a web browser or Netflix (which I believe the newer models have).
My only expectation for a HTPC/Meida player really are:
- Ease of Use
- Integration into Home Theater
- Ability to stream many media formats (up to 1080p) and play back smoothly
- Ability to stream online content (specifically, Netflix)
- Web Browser
I recently was in San Diego visiting friends and one of them had the new Logitech Revue Google TV based device hooked up! I was intrigued because I’m a bit of a gadget guy and anything home theater related immediately catches my eye. After poking around with it for a half hour or so, I decided once the funds became available that I would purchase one myself and give it a whirl.
What really set the Google TV apart for me is that it’s not just another home theater component, but more an extension of your current DVR/STB by living “in-line” between your STB and your Television. In my eyes, this is what makes it a more valuable addition to any home theater.
So let’s dive into my expectations and how they were met:

What a Difference a New Chipset Makes
Posted by eric in Hardware, Networking, Reviews on January 17, 2010
My system for the last few years has been a Dell Dimension 9200. I’ve done a few upgrades to it that were non-Dell standard but for the most part it has been completely stable and without issue. That was until recently… when I installed a new nVidia GTX 295 video card. I had thought outside of the SLI on a single card that I wouldn’t experience any issues. My mistake.
Soon after installing the GTX 295 I started experiencing strange issues. 3D Performance was in the pits, video playback had issues and even sound while playing a game was choppy and stuttered. I was at a loss for what could have been happening because I had the latest drivers from nVidia and did a fresh install of Windows 7 x64 Enterprise Edition.
Then I remembered last time I had the symptom of stuttering sound…
Review — Western Digital TV Live HD Media Player
Posted by eric in Audiophile, Hardware, Miscellaneous, Multimedia, Reviews on January 10, 2010
I recently started creating backups of my home Blu-Ray library without any method to play these backups on my home theater. My media playback device of choice, the XBox 360, is unable to play any video files that are within an MKV container. I had played around with MP4 containers as an alternative but the Windows Networking component of the XBox 360 limited the file sizes to the FAT32 limit of 4GB, which is too small to host an entire 1080p movie and I was unwilling to split the backup into multiple files.
The available alternatives out there didn’t seem technically feasible as most D-Link and Linksys offerings are merely Windows Media Center Extenders with “support for MPEG-4/ASP” (read: DivX) but no support for MPEG-4/AVC or MPEG-4/VC1. The option of setting up another HTPC for my home theater wouldn’t be financially viable because at a base price of about $399 I might as well invest in a Blu-Ray burner to watch my backups.
Enter the Western Digital TV Live HD Media Player…

Review: Intel SS4200-E NAS
Posted by eric in Hardware, Networking, Opinion, Reviews on September 12, 2009
Well, it finally happened. The D-Link DNS-323 NAS that I’ve been using for the past two years with a 750GB RAID1 finally filled up 
The DNS-323 has been a great NAS! I had my doubts at first with a D-Link product, since in the past their networking products that I’ve used haven’t been quality. So my issue was, how do I upgrade from a RAID1 on a two-drive NAS to a new fault tolerant system that has at LEAST 1.5TB of storage. I mean, if you’re going to upgrade you need to make it count, so doubling the capacity of my current NAS was the primary goal.
I did some research and with NewEgg running a sale on the hardware, I settled on the Intel SS4200-E NAS. On the spec sheet, this NAS met my requirements because it supported up to four drives, RAID5 and RAID10! Technical reviews I found of the device put it at the top of the chart when it comes to RAID5 performance.
Upgrading my HTPC — It’s Alive!
Posted by eric in Hardware, Internet, Miscellaneous, Multimedia, Reviews on August 24, 2009
A couple months ago I posted a blog entry about my plans to upgrade my Home Theater PC (HTPC) using the new Zotac IONITX
Intel Atom based motherboard. As a point of reference, I’m upgrading my HTPC from an underpowered, but pretty sweet at the time VIA EPIA-M 600M. My reason for using the 6000 at the time was I wanted a fanless setup to the HTPC would be as silent as possible.
The case I’ve been using is a Morex 3677B case, which is fairly small but still allows enough room for a 2.5″ Hard Drive and a Slim Laptop CD/DVD drive.
A couple gotchas I ran into while upgrading from the VIA board to the new Intel Atom based board:
Apple releases fix for wireless latency issue caused by 10.5.8 update!
Has wireless latency gotten you down? Have your internet porn habits been impacted since you updated your Macbook or Macbook Pro to 10.5.8?
ME TOO AND IT WAS DRIVING ME UP THE FUCKING WALL! 
After I updated my 15-inch Macbook Pro to 10.5.8 I noticed right away that my wireless performance was in the crapper. Ping times to Google jumped up to an AVERAGE of 300ms, sometimes as high at 1,500ms! Any other wireless device in the house? 40-50ms! So it was obvious, after pulling my hair out thinking it was an issue with my Airport Extreme base stations or Verizon FIOS.
Luckily my friend Joe (who has been suffering the same issue), pointed me towards a link on Apple Support that not only admits that the 10.5.8 update breaks “some” Intel based laptops, but they also released a fix! What was their fix?
It basically rolls back your wireless drivers to 10.5.7!

I hope this helps out anyone else who thought they were losing their mind! 
Cheers!
Problems with nVidia cooling over long term?
Posted by eric in Hardware, Miscellaneous, Windows Vista on June 15, 2009
I’m an avid SETI@home cruncher have been for years. My bragging note is that I recently passed 3,000,000 credits on SETI@home and part of that is thanks to the SETI@home CUDA enabled client they released which enables GPU crunching of SETI@home work units!
I’m currently running the CUDA client on two machines that have video cards that support the CUDA API. My home GeForce 8800GTX and my work Quadro FX 4600. From what I’ve read in specs and reviews, they’re basically the same card. So although this issue isn’t TECHNICALLY apples to apples, there might be a connection.
I noticed after a month or so of running the CUDA client on my home GeForce 8800GTX, my Vista machine started to become unstable. Blue Screening (BSOD) or rebooting randomly. It struck me as odd because I had not changed anything and for the most part, the system had just been sitting idle crunching work units.
Your GPU running SETI@home CUDA Client
After some basic trouble shooting I was able to determine that the instability was due to my video card overheating! This struck me as strange, because I know nVidia uses variable speed fans on the 8800GTX, so you’d think that if the system was reaching an unsafe operating level, that the fan would kick on, right? Wrong.
