Patiently waiting for EOS 5D Mk II

Canon announced the update to the EOS 5D on September 18th, more than three months ago. Now the holiday season is all over us and there are still no EOS 5D Mk II to be found – at least not here in Sweden.

Canon recently announced some demonstration films showing off the video capability that this camera – together with some good optics – can deliver. The result is absolutely astonishing. I will have to reevaluate my assumption that I wouldn’t use the video feature.

Now I only wish that Canon could learn something from Apple. If they announce something they should have it ready for delivery. I’m getting tired of the waiting and if they don’t start shipping these babies in volumes my allocated budget may be put into use for some other gadget.

Web classic: How real men start their grill

This is a partial quote from early WWW sources. I would gladly give credit to someone but I don’t know who wrote the original text. I remember reading it around 1995 while I was still at University, looking at the video on the Sun computers in the lab. Nowadays just about anyone posts videos on YouTube but Goble and his colleagues were among the pioneers.



A guy named George Goble (really!!), a computer person in the Purdue University engineering department. Each year, Goble and a bunch of other engineers hold a picnic in West Lafayette, Indiana, at which they cook hamburgers on a big grill. Being engineers, they began looking for practical ways to speed up the charcoal-lighting process.

“We started by blowing the charcoal with a hair dryer,” Goble told me in a telephone interview. “Then we figured out that it would light faster if we used a vacuum cleaner.”

If you know anything about (1) engineers and (2) guys in general, you know what happened: The purpose of the charcoal-lighting shifted from cooking hamburgers to seeing how fast they could light the charcoal. From the vacuum cleaner, they escalated to using a propane torch, then an acetylene torch. Then Goble started using compressed pure oxygen, which caused the charcoal to burn much faster, because as you recall from chemistry class, fire is essentially the rapid combination of oxygen with a reducing agent (the charcoal).

By this point, Goble was getting pretty good times. But in the world of competitive charcoal-lighting, “pretty good” does not cut the mustard. Thus, Goble hit upon the idea of using – get ready – liquid oxygen.

This is the form of oxygen used in rocket engines; it’s 295 degrees below zero and 600 times as dense as regular oxygen. In terms of releasing energy, pouring liquid oxygen on charcoal is the equivalent of throwing a live squirrel into a room containing 50 million Labrador retrievers.

You can see actual photographs and a video of Goble using a bucket attached to a 10-foot-long wooden handle to dump 3 gallons of liquid oxygen (not sold in stores) onto a grill containing 60 pounds of charcoal and a lit cigarette for ignition. What follows is the most impressive charcoal-lighting I have ever seen, featuring a large fireball that according to Goble, reached 10,000 degrees Fahrenheit.

The charcoal was ready for cooking in – this has to be a world record – 3 seconds. There’s also a photo of what happened when Goble used the same technique on a flimsy A2.88 discount-store grill. All that’s left is a circle of charcoal with a few shreds of metal in it.

“Basically, the grill vaporized,” said Goble. “We were thinking of returning it to the store for a refund.”

Extract image metadata

Over the years I have used many small applications to extract metadata from images but none of them were as versatile as Image-ExifTool by Phil Harvey. It support just about any image or video file format your can imaging. And a nice thing is that it is implemented in Perl so that one can easily use it to build a script. And it works cross-platform which is important for me who move between three operating systems on a daily basis.

This is all it takes to extract all metadata from a file:
