Bento 3 just released
Unlike Lightroom, Bento 3 leverages Apple’s Bonjour technology so you can now share your Bento libraries with up to five users over a wired or wireless local network. You can also encrypt any field and assign passwords to secure your information in Bento 3.
The new Grid view in Bento 3 delivers an innovative method of displaying thumbnails of photos, text and numeric-based information, while improved File Lists show image thumbnails, instead of just text.
Best yet, if you own Bento 1 or 2, upgrade pricing is only $29. It's hard to beat that price.

AVCHD codec?
"One challenge of the AVCHD format is that it can be stored on a variety of media. Unlike Mini DV and HDV which are stored on Mini DV tape, AVCHD can be stored on DVDs, memory cards and internal memory (i.e., hard drives and Flash memory). With all these storage possibilities, it can be frustrating as an editor to find a way to import all of it into your machine. If you're editing a video for a friend or client, you may need them to bring in their camcorder and not just their media. Further complicating the matter is that many shooters end up transferring the footage to their PC to clear their memory card or internal memory. With the footage stored on a hard drive, it may not be compatible with your editing system or software. It all depends on how the shooter got the footage off the camcorder and onto the PC.
Many AVCHD camcorders ship with software that allows shooters to import the footage in its native format. This is useful for doing simple playback of your footage. Other applications will also allow you to convert the footage to a different format. For example, Panasonic's Professional Video division has a software tool that will convert AVCHD to their ProHD video format, which is much more compatible in professional editing environments."

Making forensic science scientific
Establishing national forensic science standards is crucial when evidence determines life or death.
"... In 2006, Congress charged the National Academy of Sciences with studying the application of forensic science in the U.S. judicial system. Its findings, released last year, are grim. Almost every branch of forensics but DNA testing -- hair and fiber analysis, arson investigations, comparisons of bite marks -- lacks the extensive scientific research and established standards to be used in court conclusively.
Consider: Last year, the Innocence Project, a New York-based public policy and litigation organization, helped exonerate Kennedy Brewer, a Mississippi man who had been convicted in 1992 of raping and killing a 3-year-old girl. DNA testing was not available at the time, and the primary evidence against him was that bite marks on the child's body matched his teeth. Examination of the marks by national forensics experts determined that they were not even made by a human mouth: Her body had been dumped in a pond and insects had attacked it. Subsequent DNA testing also excluded Brewer as the rapist.
In February, the science academy issued a report calling for Congress to create a national institute of forensic science, and there is more than enough evidence that one is desperately needed. As an independent agency, not part of the Justice Department, it would be charged with conducting research, setting national standards for forensic disciplines and enforcing those standards. Right now, standards vary wildly. An expert in San Diego, for example, might testify that a fiber is similar to one found at a crime scene, while an expert in San Bernardino might testify that a match is impossible to determine.
Advances in forensics have revolutionized the judicial system, aiding both prosecutors and defense attorneys, exonerating the innocent and confirming the guilty in ways that were impossible just a generation ago. The patchwork state of forensic science should not become an excuse to shy away from its use; rather, the nation should invest in the rigorous research required to standardize techniques and application. ..."

Book Review - Ordinary Injustice: How America Holds Court
Caution Recommended With Bitemark Evidence
"Against the backdrop of last week's Congressional hearing into the future of forensic science, researchers from the University at Buffalo's Laboratory for Forensic Odontology Research in the School of Dental Medicine, have published a landmark paper on the controversial topic of bitemark analysis.
The Congressional hearing focused on the findings of a National Academy of Sciences (NAS) report on the scientific basis of forensic disciplines. Among the pattern evidence fields (fingerprints, tool marks, etc.) that were reviewed in the NAS report, bitemark analysis received critical commentary. During the hearing, Innocence Project co-founder Peter Neufeld introduced Roy Brown, wrongfully convicted on bitemark evidence and later exonerated through DNA analysis.
In anticipation of the NAS report, the new UB study published in the Journal of Forensic Sciences challenges the commonly held belief that every bitemark can be perpetrator identified.
"Bitemark identification is not as reliable as DNA identification," explains the study's lead author Raymond G. Miller, D.D.S., UB clinical associate professor of oral diagnostic sciences.
"With DNA, the probability of an individual not matching another can be calculated," he says. "In bitemark analysis, there have been few studies that looked at how many people's teeth could have made the bite."

What's this? CCTV helps solve just ONE crime per 1,000
The startling figure comes in a Scotland Yard report which warns that a network that can capture individuals as many as 300 times a day is failing to improve public safety.
Officers found that the million cameras covering London have helped clear up barely 1,000 crimes.
Critics say the revelation should lead to a wholesale shake-up of the hugely costly CCTV system.
The senior Metropolitan Police officer behind the report warned of a crisis in public confidence over the use of surveillance cameras.
Detective Chief Inspector Mick Neville said: '£500million has been spent by the Government on cameras. Despite this, in 2008 less than 1,000 crimes were solved using CCTV despite there being in excess of one million cameras in London.'
He said that of the 269 robberies reported in one month only eight were solved with the help of CCTV footage.
The study, part of a drive to make better use of the network, follows warnings from senior Scotland Yard officers that criminals are not deterred by cameras because they assume them not to be working.
Detectives are thought to be reluctant to scour hours of recorded footage 'because it's hard work'.
Although the UK has an estimated 4.2million cameras - giving it the world's biggest surveillance network - a Home Office report conceded earlier this year that camera schemes have had only a modest impact on crime. ..."

Hack your camera?
We love point-and-shoot pocket cameras for their small size and ease of use, but we lament their relatively paltry feature sets when compared to more expensive DSLR models. The good news, for owners of the popular Canon PowerShot cameras, is that your consumer-grade gadget can be upgraded with custom software to endow it with professional features like RAW image recording and live histogram feedback. CHDK (Canon Hack Development Kit) is an easy-to-install software package created by a savvy group of programmers to supercharge the Canon PowerShot. We show you how to safely install and configure this free firmware add-on with no risk to your camera.

Foolproof Forensics?
The world of forensic science has been in turmoil for the last six months since a prestigious panel released a study raising serious questions about many forensic techniques from hair analysis to fingerprints.
Those techniques have collectively resulted in thousands of people landing in prison — and now groups within the forensic science community are fighting over what the next steps should be.
Physicist Thomas Bohan says scientists knew for years that many forensic techniques "lacked scientific evaluation," but there was no political will to do anything about it. Now the report by the National Academy of Sciences offers "an opening, an opportunity," Bohan says.
"It will be a terrible shame if change doesn't take place," says Bohan, who is president of the American Academy of Forensic Sciences.
An Argument Over Next Steps
But every time there is a push for change, there are political battles about what kind of change is best. The debate over forensic science is no different.
Crime lab directors want bigger budgets and more staff. Scientists want to start with research into which forensic techniques are valid.
Some key recommendations from the people who wrote the report don't have much support from anyone. For example, the report recommends creating an independent organization to oversee forensic techniques.
"There is no entity like this right now," says Constantine Gatsonis, who co-chaired the committee that wrote the forensic sciences report. "And hence what you've seen is every entity pulling in [its] own way. My personal opinion is that real progress is going to be very difficult without such an entity."
But that proposal now looks all but dead.
Scott Burns, executive director of the National District Attorneys Association, says his members "don't agree with setting up a national institute of forensic science, another bureaucracy."
Congress will make these decisions. And a Senate Judiciary Committee staffer — speaking on condition of anonymity because the matter is still under discussion — said that in this economic climate it seems unlikely the government will create a new body to oversee forensic science.
