Perhaps I’m missing something, but it seems to me that recent advances in digital video aren’t getting the attention they deserve.

It’s not that they are going entirely unnoticed. This recent “review of tiny digital cameras”:http://tech2.nytimes.com/2005/05/26/technology/circuits/26pogue.html?ex=1118289600&en=076d55d2f524b2da&ei=5070 in the New York Times notes the video abilities of each camera without really considering the implications of a ~$300 device capable of shooting long clips of TV quality video.

I’ve been tracking this since I noticed that the clips shot by my first digital camera, a Nikon CoolPix 990, reminded me of old 8mm home movies. The resolution was poor, the focus was questionable, the colors were oversaturated, the motion was jerky and blurred and the audio was non-existant, but it captured something that a much better still photo couldn’t.

My second digital camera, a Canon PowerShot S400 I bought 18 months ago, improved things somewhat. The image quality had improved a little, but I could shoot up to 3 minutes at a time (longer than a lot of takes in TV and movies), and there was poor quality audio to go along with it. Most importantly, I could carry it in my pocket and the movies were almost as easy to mail around as the photos I took.

Since then, I’ve been waiting for the next step, and we are finally there. My brother just e-mailed me a short clip of my nephew singing me happy birthday that he’d taken with his new Canon Powershot SD400 (or maybe it was the Canon SD500, which has identical video capabilities). The clip was 640×480 @ 30 frames/second, Details were crisp, motion was smooth and there weren’t a lot of ugly compression artifacts. The audio wasn’t bad either (which isn’t to say it was good). Best of all, the camera is about the size of a deck of cards or a pack of cigarettes (depending on your vice), so you can take it anywhere, and you can record until the memory card fills up.

I’m betting that my brother’s DV camcorder is going to see a lot less use now, and I’m sure his won’t be the only one.

Don’t get me wrong, camcorders are better by a lot of criteria. They have lenses with a wider range of zoom, they work better in low light, have better autofocus, image stabilization, more storage, better audio (including the ability to use an external microphone), and a form factor that is probably better for long stable shots but they suffer alot in the convenience department, most are relatively bulky compared to a small camera, and they transfer video in realtime (1 minute of video takes a minute to transfer to your computer).

These new digital cameras, on the other hand, offer good video quality under good lighting and I’d guess that people aren’t going to mind a little jumpyness and mono audio if it means catching a clip of their kids first step they wouldn’t otherwise get.

All this suggests a few opportunities to me. Camera reviewers should be going into more depth on the video abilities of cameras. At this point, they just cover the basics, like resolution, frame rate, and maybe average data rate and maximum clip length. I’d like to know more: what’s the image quality like? are there obvious compression artifacts? can I zoom during a clip? does the camera do a good job of adjusting the focus as the main subject of the scene moves? etc.

Software makers could make it as simple to compress a clip to share with friends and family on the net as they do for resize photos for emailing. Image stabilization in software would also be cool.

It’ll be interesting to see where things go from here.

I’m watching a streaming clip from C-SPAN from a recent Gartner IT Security conference. Bob Woodward is giving opening remarks before the panel discussion starts. Just as he is turning it over, he recounts a dinner with a muckety muck with Simon and Schuster after he published his last book. The exec asks Woodward what his next book is going to be, and has a rather crass and commercial response to to Woodward’s thoughtful evasion. At the end of the dinner, Woodward say’s he’s found his topic, he’s going to write about the publishing industry in New York. The exec responds with a thinly veiled threat, which Woodward takes seriously, that such a book will be the last book Woodward publishes.

The “clip”:rtsp://video.c-span.org/project/ter/ter060605_cyber.rm is in Real video format. The comment comes about 14:00 in.

The publisher’s threat makes me glad we have alternatives to the old mass media.

I’ve long used a shortcut in firefox to do google searches. Rather than relying on the tiny built in search box, I just type “goo blah blah blah” in the URL box and it uses a special bookmark I created to search “blah blah blah” on Google. I’ve also set up a few others as well.

What’s really easy is that they make it extremely easy to set up new search shortcuts. Just right-click on the search box on almost any web page, and you should see an option in the popup menu to add a keyword for this search.

Old 97s! Find, listen! LIVE VERSION!

I few weeks back, I revamped my home network to deal with a flakey router and what proved to be flakey firmware on an otherwise solid pair of wireless router/access points.

The flakey router was removed, and “HyperWRT firmware”:http://www.hyperwrt.org was installed on the Linksys WRT54G router/access points. One of them was configured to serve as my internet firewall/router. Both “were configured for WDS”:http://www.linksysinfo.org/modules.php?name=Forums&file=viewtopic&t=2946 to allow the 2nd device to provide access for a wired PC in the living room and extend the range of the wireless network.

Everything worked well, much better than before, but in the back of my brain, I was nagged by the fact that my network was only secured by the “increacingly vulnerable WEP standard”:http://www.tomsnetworking.com/Sections-article120.php. Even worse, the new firmware seemed to offer an alternative by offering support for the more secure WPA standards.

Unforutnately, my first foray broke my link to the living room. I configured both WRT54Gs to use WPA Preshared Keys with TKIP. The result was that my laptop wouldn’t connect and my WDS link would fail after a small amount of time. The laptop problem was fixed by updating the driver.

The WDS problem was stickier. I learned that the overlap between TKIP and WDS is underspecified. There are some solutions to the problem, but it wasn’t clear to me what they were. There were some reports of getting wds to work with AES instead of TKIP, but when I first tried it, it failed.

This morning though, when I was going to roll everything back to WEP, I noticed that everything seemed to be working. After some investigation, it seems that the AES option is shorthand for an even more recent set of protocols that make up the WPA2 standard. It specifies both a method of authentication and key management that goes beyond TKIP while interoperating with WDS. In addition, it uses the AES encryption standard, which is more secure than the standard used by WEP and WPA/TKIP.

The only downside is that AES is more computationally intensive. The result is that my older hardware is an even bigger bottleneck than before. With WEP I was able to use about 50% of the theoretical 54 Mbps offered by 802.11g. With WPA and AES, I can only use about 25%.

*Update:* It appears I am wrong about the throughput. The Broadcom chipset used in the WRT54G has a hardware encryption accelerator and various reviewers report no obvious penalty for using AES. I even tried myself, by temporarily disabling encryption and transferring the same large file as before. I didn’t see any difference either. It looks like real-world bandwidth for 802.11g is ~11-25 Mbps, which is about what I was seeing.

Bummer. I guess I’ll have to keep an eye out for when 802.11n gear gets cheap. That, or finish running Cat5 between my office and living room as I set out to do last fall.

In a recent episode of Law & Order: Criminal Intent featuring a plot-line about the murder of a federal judge, a cop quipped:

bq. “Maybe we should put out an APB for somebody in a Tom DeLay T-shirt”

Now DeLay is having a hissy-fit:

bq. “This manipulation of my name and trivialization of the sensitive issue of judicial security represents a reckless disregard for the suffering initiated by recent tragedies and a great disservice to public discourse.”

Creator/executive producer Dick Wolf, one of the most visible Republicans in the entertainment industry calls bullshit: “I do congratulate Congressman DeLay for switching the spotlight from his own problems to an episode of a television show.”
