Mobility and dancing bears

Filed under: Web — Preston @ 12:58 pm

I am with Tim and Jeremy here … and while Russell has a point, he is just about completely wrong :) .

Size is the problem.

Cell phones are small. In fact with the current generation of phones they are too small – at least in the keyboard. Unless you are a kid or a skinny Asian female the size and placing of the buttons on the phone is a lot smaller than your fingers. This is just bad design.

(Why is it the very latest cellphone/gadgets are usually shown with skinny Asian females? … oh nevermind).

For talking cellphones are great. For sending short text messages (I have a teenager) cellphones are – a bit of a pain but tolerable. For web access – between the tiny screen and tiny keyboard – cellphones are a dancing bear.

“The wonderful thing about a dancing bear is not how well he dances, but that he dances at all.”

My new cellphone has a (lousy) builtin camera, with truly brain-dead supporting software/GUI in the phone, and an uninspiring picture gallery at the phone company site. Dancing bear time again.

No, I don’t have a PDA or cellphone/PDA hybrid. Ever see the George Carlin routine about different versions of “stuff”? PDAs are little limited computers with small screens and way-too-small keyboards. One friend is on – I dunno – his sixth(?) PDA. Seems to be more of a hobby than a useful tool.

Cellphones are great for talking. Bluetooth to a wireless headset sounds pretty nice, though with my latest cellphone has a “speakerphone” mode, I have almost stopped using headsets. Flat-rate high-speed connection to the Internet via bluetooth to my notebook sounds like a killer app – if you can talk at the same time.

I will take usable and useful over whizzy every time :) .

Doctors are doing just fine…

Filed under: General — Preston @ 8:22 am

Despite their malpractice premiums, America’s doctors are doing just fine.

Guess the rumors that HMOs and Insurance companies were cutting into doctors incomes is not of concern.

This still bothers me…

Back when the Republican Convention was in New York, there were a number of arrests that I find … disturbing.

First there was the guy with a bike that wrote messages on the sidewalk in washable chalk. You could send messages to be written by the bike from his website. Overall a pretty clever idea. He was going to ride around during the RNC writing other folks words on the sidewalk. A pretty neat twist on freedom of speech :) .

He was arrested by the NYC police – while being interviewed for TV. Personally I think it a bit of a stretch to arrest someone for writing with washable chalk. Sounds too much like an excuse, given the “damage” washes away with a bit of water. Seems somehow that “freedom of speech” should have weighed in here in favor of not bothering this guy who was clearly not out to do any real harm (not counting political damage).

As a side note – it took the police the better part of an hour to decide if they should make an arrest. I wonder if they would have taken as long if there were not TV cameras present?

Though he was released somewhat later they kept his equipment through the RNC and up to the present. Guess he won’t get his stuff back until after the election. Funny how that works out…

Around the same time the NYC police arrested a large number of other people for riding bicycles (doubtless a dangerous activity) or for just being in the general area.

I have a hard time seeing the arrests as anything other than politically motivated.

Wildfire

Wildfire
By John McColgan of the BLM Alaska Fire Service. [large image]

The image was captured in the late afternoon of Sunday, August 6, from a bridge over the East Fork of the Bitterroot River just north of Sula, Montana. The elk sought refuge in the river bottom during what may have been the most extreme day of fire behavior on the Bitterroot in more than 70 years. “I do shoot some photography, but certainly that was a once in a lifetime, stunning opportunity.”

He was traveling to the Valley Complex along with the deputy incident commander of the Sula Complex. “I was on that ridge for maybe 15 seconds.” “We just saw the elk, and I stopped and said, ‘I’m taking 15 seconds here.’” McColgan said the photo does not fully convey the extreme weather conditions that day. “It was a fairly violent situation out there,” he said. “It looks fairly serene, but the wind was really whipping.”

McColgan used a Kodak DC 280 digital camera, set at high resolution (1,792 x 1,200), but also at a medium to high level of compression to save on storage space. “I wasn’t out shooting art photos. I was doing fire behavior documentation.” After the photo was taken, it circulated widely and anonymously until it got picked up by the Associated Press and the Montana newspaper “The Missoulian.” “I had given a copy to someone while I was down there [in Montana], and it inadvertently made its way into the e-mail system.” He received e-mail from friends in Europe, sending the photo back to the US and asking him if he’d seen it.

Since McColgan was working as a Forest Service firefighter, the shot is public property and cannot be sold or used for commercial purposes

Although the photo originally went out with no credit information, a reporter from “The Missoulian” tracked the photographer down at home in Alaska. McColgan, who normally works as a fuels management specialist for the Bureau of Land Management Alaska Fire Service, doesn’t mind the lack of credit, or that he can’t use the photo to make a profit.

As McColgan described the experience to a writer for the Western Montana newspaper The Missoulian:

“That’s a once-in-a-lifetime look there. I just happened to be in the right place at the right time. I’ve been doing this for 20 years and it ranks in the top three days of fire behavior I’ve seen.”

The day was Aug. 6, the Sunday when several forest fires converged near Sula into a firestorm that overran 100,000 acres and destroyed 10 homes. Temperatures in the flame front were estimated at more than 800 degrees. Nevertheless, McColgan said, the wildlife appeared to be taking the crisis in stride, gathering near the East Fork of the Bitterroot River where it crosses under U.S. Highway 93.

“They know where to go, where their safe zones are,” McColgan said. “A lot of wildlife did get driven down there to the river. There were some bighorn sheep there. A small deer was standing right underneath me, under the bridge.”

John McColgan has been a wildland firefighter for 20 years. He currently works for the Department of Interior, Bureau of Land Management, Alaska Fire Service as a Fuels Management Specialist. John coordinates fuel management and prescribed fire activities for the BLM in Alaska. During fire season he serve as a Fire Behavior Analyst on the Alaska Type I Incident Management Team. John has been in Alaska since 1989 where he has worked with the Alaska Smokejumpers for 10 years. Prior to 1989 he worked on hotshot crews with the National Park Service in Sequoia-Kings Canyon National Park and with the U.S. Forest Service on the Mt. Hood National Forest where he started my wildland fire career. In 1987, He graduated from Colorado State University with a bachelors degree in Natural Resource Management with an emphasis in wildland fire science.

Web criminals & Whack-a-mole

Filed under: Web — Preston @ 11:41 am

Tim Bray writes about Crooks in Plain Sight and asks “What am I missing?”. Why do we have web criminals when the sources are so easy to identify?

In fact the lack of sense it is much worse (or better – depending on your point of view).

It is easy to shut down script kiddies, if you have lots of time to waste. It is not too hard to identify machines sending spam, or websites hosting scam artists. In the end this is about as effective as playing a game of Whack . A . Mole. There are an almost endless number of clueless teenagers, unsecured machines, and careless webhosts.

Still the problem is entirely solvable. How do you avoid scam artists in real life? Know who to trust.

Trust can be built into algorithms.

Want to shut down spammers at the source? Block outgoing SMTP connections for most customers. Count the number of emails sent per hour or day. Shutdown accounts with unusual activity. Trust your users as you would in real life – let experience be your guide. A new user who starts posting hundreds of messages should get your attention. An old user (someone you have come to trust) would get less attention.

Handle irresponsible ISPs by blocking all traffic until they get their act together. Script kiddies are easy to spot – setup honeypots.

Want to shutdown scam artists? Follow the money. Create “poison pill” accounts with the credit card companies. Shutdown the business account of anyone who trys to use a poisoned account. Cut off a scam artist’s money, and you make their business a lot less attractive.

Want to spot spammers who harvest email addresses and clearly are in violation of “opt-in” requirements? Plant “poisoned” email addresses on USENET newsgroups and bogus websites. Anyone sending to a “poisoned” email address is almost certainly dishonest.

Cutoff the money, the email, and the ISP used by dishonest folks and you can pretty much wipe out the problem.

A viewpoint – War in Vietnam

Filed under: Politics — Preston @ 9:54 pm

A well-expressed viewpoint from someone who served in the War in Vietnam.

Oil wars?

Filed under: Politics — Preston @ 9:52 pm

The chaos in the world oil markets and the resulting record high prices must be extremely profitable for some. If you are an oil producer and your production is unaffected, you are now accumulating an enormous extra pool of cash. Clearly it is in your interest for prices to stay high. Funding a bit of chaos in other oil-producing regions could prove highly profitable.

Reading the news, I have to wonder if this has already begun. Perhaps that is part of the troubles in Iraq? Other oil-producing outfits/countries have interest in seeing oil production in Iraq kept limited. Funding terrorists is relatively cheap compared to the profits brought in by high oil prices.

Welcome to the Oil Wars?

Server-side Java performance

Filed under: Software — Preston @ 6:49 pm

Admittedly I am something of a performance freak. I have a knack for understanding the potential performance of an application. This has meant picking up existing software and radically improving performance. This means writing new software that performs at the limits of the hardware and out-performing the contemporaries.

Working with the existing Java web servers and frameworks I am bothered by the sense that all this well-thought and carefully abstracted software is somehow far from the potential limits of performance. Understand that I am not saying all this software is badly written. Rather the exercise of boiling down the critical path through an application to just essential steps is quite difficult.

Seems that Greg Wilkins is having somewhat similar thoughts at least in regards to Java Servlets.
