Notes from the Prez

by Jim Dinkey

All too often the assumption is that because you don't have very sensitive data on your computer that you don't need to assure that your wireless is encrypted.

Unfortunately, that is just not the case in the modern world.

While it has yet to be tested in court, your computer could:

All of these things can happen if you are not using the “G” option of the wireless versions or if you have not updated your wireless to the WAP2 version of the encryption algorithm.

But you might say, “I have WEP going, I am invulnerable.”

Think again.

Neither WEP nor dynamic WEP can be relied upon. WEP can be cracked with standard tools in minutes or seconds. Dynamic WEP can be cracked almost as fast.

WPA2, which comes with any “G” version, seems to be holding up quite well. All the others need to have downloadable patches to all “B” or other non “G ”wireless equipment.

So the message for the month is to review the status of your wireless setup and act accordingly.

Since 60% of the present wireless users do not have any encryption at all, the outlook is quite bleak, but at least you are savvy enough to know to take care of the problem. The manufacturers want to avoid having support calls because the wireless device they sold doesn't work. That is fair enough, but the manufacturers seem to bury very deeply in their instructions how to enable encryption. For this I fault them greatly. So if you get into a court hassle, still blame it on the manufacturer.

Presentation

Gary Sasaki gave a fascinating presentation on six themes in the consumer electronics world. He showed how "s-curves" explain and predict how industries evolve through different phases. The PC industry has gone through the "three gears" already. The introduction of the DVD started the Home Media industry in 1995, and the industry is now in (or almost in) "second gear". This means there is still a lot of "vapor ware" and hype, and prices are still relatively high (though lower than they were in "first gear"), but various products are actually on the market, and are being bought by "early adopters". In "third gear", you get high volume and good profit; but in "overdrive", there is high volume but low profit, and manufacturers start merging or shifting to other markets.

High Definition Television (HDTV) has not been available in "native resolution" until this year. The Digital Media Adapter (DMA) allows you to connect other appliances to each other (digital camera to TV, for example). It was supposed to be the "next big thing", but really hasn't caught on; this leaves a lot of early adopters rather dissatisfied. Implications of "second gear" are, the "big guys" have staked out the good territory, and there is a huge "entry fee" to get a product developed to compete with them.

Internet Protocol Television (IPTV) will function with the new high-speed ADSL Two Plus (~20 Mb per second) to pipe media to you over the Internet. Bill Gates and SBC demonstrated the technology, but it is not yet available. They will add video phone capablility to the TV capability. You will be able to download, record and/or watch four programs simultaneously. Interactive TV will become feasible, and along with it, video on demand. You will be able to switch among several different feeds for sports events. These capabilites will be touted as "must have" features to attract market share from competitors.

There are two forms of HDTV, 1080X1920 pixels and 720X1280. It would be safer to get a 1080X1920 pixel model, and finally this year Samsung, Sharp, Philips and others will finally offer models. They will be expensive, though. High Definition Multimedia Interface (HDMI) is something else to look for. It has encryption built-in, and will future-proof your TV. HDMI is showing up in other accessories, too. You also want to be able to record HDTV; the standards are still being finalized, and there may be a "Betamax-VCR" kind of shake-out, so don't be an early adopter.

The implications of these developments are the public will find out HDTV-ready is "bait-and-switch", becasue it does not include the HDTV tuner. Remember, to be true HDTV, you need a native resolution of 1080X1920 pixels or 720X1280, and preferably the former. Other resolutions will degrade quality or result in an inferior display. Enhanced Definition Television (EDTV) is the progressive version of the current interlaced 480X720 display. Get 1080X1920 pixels in native resolution if you can afford it.

The display is the business end of the TV, and will come in a huge variety of sizes and technologies. This year the rage was LCD, which is best for smaller size screens, e.g., $800 for 30"; last years rage for plasma has receded. Sharp makes a 65", but it's really for commercial uses (bars, hotesl, etc.). Genoa has added more colors to their LCD (magenta, yellow and cyan) to improve color presentation. There are other display technologies being developed; some will be very expensive, others (like SED, GXL, etc.) will allow great manufacturing cost savings, but only if the technology can be successfully developed. LCDs are generally reliable except for "infant mortality" problems. Sony's Blackscreen technology, with special coating to reflect only red, green and blue, will improve projection TV displays by rejecting ambient light. Projection bulbs are quite expensive ($400-500), and will limit the popularity.

Digital Cinema is beginning to evolve; all aspects of the system are digital. Star Wars Three will be best seen at Century 22 in San Jose; it is one of the few to have Digital Cinema at 1080X1920 pixels. Even higher resolution is coming for Digital Cinema.

The Media Center PC concept is developing and evolving. Network Attached Storage (NAS) will be developed to store your digital media. Many functions are being added to non-pc appliances - record to DVD, internal hard drive, TiVo in high definition, will be in competition with the PC. Cat-5 coax cable will be used most often for a while to distribute the media around a house. Other options exist, but are not as economical or simple.

The iPod will be copied extensively, and there will be added features to the point that they will be difficult to operate. Cell phones will start offering the same capability. Buying a ring tone can be more expensive than buying the whole song (so selling ringtones is more profitable than selling songs), so phones will also undergo "feature creep", and consequently become more difficult to operate, and battery life will become a limiting factor to its use. Quick-charge batteries (~ 1 minute to fully charge) may alleviate that problem.

DVD Burner Evaluation

by Robert Mitchell

I just installed a Pioneer A09XL DVD burner on my machine and it works great. It is a 16x DVD Burner with dual layer burning. I have made slide shows with the ULEAD Software that came with it, and made a fews disks. I have been using 8x Memorex disks and the DVD software wrote them at 12x. All the disks worked fine in the standard DVD player.
I think the CPU minimum requirement is at least 800MHz P3 chip with 256 MB of RAM, but the P4 that I have is more reasonable, and of course the faster the machine and the more memory it has, the better.
I have a 2 GHz Pentium 4, 512 MB of RAM and two 60 GB Hard Drives, WinXP SP2. Plenty of Free Hard Drive Space.
I haven't tried out the Dual Layer disks yet, since they are still pricey. A package of 3 for $20 to $25 a set. The only brands that I saw so far, are Vebatum. Fuji and one other (can't remember).
I am using the Ulead software that came with drive and works very well. 12x speed is a transfer rate of about 16.6 Megabytes per second. When making a disk, it is the encoding steps that take the longest. The actual burn of the last disk took about 10 minutes.
[N.B.- everyone knows that for more reviews, hardware minimum requirements and online purchase you just type the keywords Pioneer A09XL DVD into Google, right? SAH]

Homebrew Movies on the Internet

by Robert Mitchell

The other day in a San Francisco Chronical Article dated Monday May, 9 2005 (the Technology Section E), I found a link to a homebrew Star Wars movie at Panic Struck Productions called Star Wars Revelations. George Lucas actually doesn't mind people doing that as long as they don't sell it. He is happy that fans have fun with it and apply their own ideas to it.
I downloaded the *.wmv version of the movie by DSL (it took about 25 minutes to download and was around 260 MB), put the file on a DVD disk and used my computer to burn a watchable DVD. I used Ulead's Movie Factory Software 3.5 to create a DVD portion of the program). I then did the DVD rendering that took 8.48 minutes before burning the disk. Actual burn with my Pioneer A09XL using Memorex 8x (I've been consistently getting 12x out of these disks) took only about 8 minutes.The end result is quite spectacular. Lots of high level special effects that pretty much rival anything that Industrial Lights and Magic can do, but using standard off the self Animations software like Bryce and so on.
The creators used a high end Sony DV Video Camera of about $4500, a G5 Macintosh, Final Cut Pro Express +, and also some work on a Windows Machine. The entire budget for the movie was $20,000. Actors, and other work was part of that. The graphics in the movie are very realistic and the live action is good, though a little on the dark side. This show's what amateurs can do with a little money, as compared to George Lucas with 100's of thousands of dollars worth of equipment and software.
I wonder if the club might be interested in this, since it did involve the use of Animation/Graphics software and computers, Mac/Windows, etc. and video editing software. The movie is 47 minutes longs, including credits, though there is also a Trailer of about 5 minutes or so.
I have also used a free program to extract video from other non-copy-protected DVDs from our Mexico cruise. I put the file on the computer, used Microsoft's Move Maker 2 software to re-edit it to take out sections, add some pictures, and change the original movie titles.
