Microsoft hoping to replace JPEG?

I don’t know how I ended up finding this article, but here’s a good write-up on Microsoft’s new photo format.  The claim is Windows Media Photo will manage roughly double the compression ratio JPEG has while maintaining or bettering JPEG’s visual quality.  If true, this could really catch on.  Even with high-bandwidth connections more readily available, every opportunity to squeeze more signal per bit through the pipe is welcome.

“One of the biggest reasons people upgrade their PCs is digital photos,” Crow said, noting that Microsoft has been in contact with printer makers, digital camera companies and other unnamed industry partners while working on Windows Media Photo. Microsoft touts managing “digital memories” as one of the key attributes of XP successor Vista.

. . .

Not only does compression save storage space, which is especially important for devices such as cell phones and digital cameras, a smaller file can also print faster, transfer faster and help conserve battery life on devices, Crow said. “Making a file that is smaller has all kinds of benefits.”

Will this catch on?  As I said above, I can see the appeal, and if it works out as well as Microsoft is saying it will (read the article formore details of the intelligence in this format), I can only see problems if licensing costs are prohibitive or if Microsoft hate beats out throughput and image manipulation ease concerns.  Even the Microsoft rep realizes that:

Licensing details for the technology are still being ironed out. These could be a concern, Crow acknowledged, but “the philosophy has been that licensing should not be a restriction” to adoption, he said.

Honestly, I’m hoping Microsoft doesn’t pull an Apple and over-price this.  I’d like to see a better image format soon.

X-Treme tape

(via CoolTools)
When duct tape and electrical tape are not enough for you, try X-Treme tape.

Electrical tape simply does not work in a marine environment. Even duct tape won’t stick to something wet. Try getting any tape to stick to a rope or line on a boat. Or try to get a waterproof seal on a hose leak. X-treme tape can do all these chores with flying colors because it is a non-adhesive, self-bonding wrap. It’s not really tape since it’s not sticky. This stuff is sort of magical. You stretch it on and it self-fuses tight under tension. It works in cold and wet, and won’t melt on hot surfaces, so you can use it on engines.

More free books

I recently picked up an EBookwise-1150 ebook reader (now available for $124.95 with 64 Meg SmartMedia card).  I’ve purchased and downloaded a few books from the EBookwise web site, but I can’t afford to pick up as many books as I’d like there.  So when I found the manybooks.net web site to pick up scads of free books (legally free, I might add), I felt like I scored – or at scored such that I have a choice of as many as I want up to the 13,736 currently available there.  Of course, since I haven’t tried downloading any and transferring them to my ebook reader, I don’t know how much I’ve scored.  I’ll make an update when I’ve tried it out.

MAKEzine blog link dump

Here’s a big collection of projects from MAKE that I’d love to have time to do.

NPod – portable Nintendo

npod_small2.jpgBen Heck is at it again – this time he’s built a custom portable NES. His work on making classic consoles into modern portables is amazing. I’ve posted links to his stuff before, and I’m sure I’ll post links to it again. If you like the stuff you see on his web site, pick up his book Hacking Videogame Consoles (also in digital format). He’s done some wonderful work with other systems. I just happen to be most amazed by the NES work.

Make/Do magic tricks

(via MAKEzine blog)
Here’s one just for the kids.  Well, in my case, I’m interested in it just to show my kids, and perhaps to teach them.  Learn how to create and do your own magic tricks from MightyIllusions.  And as long as you are looking at this kind of thing, go to the associated optical illusions site and see some pretty cool eye tricks.

New news on lactic acid

(via DubiousQuality)

Well, this certainly falls far outside of most things I like writing about here, but I figure this comes in under some kind of science header.  Not that I need anything more than to find an article of interest to me to post it.  But still, I like to keep consistent in the kinds of drivel I post here.

Rambling out of the way, check out this article at the New York Times web site about the latest on lactic acid.  Given that it’s at NYTimes’ web site, registration is required.  To feed your interest, here’s a snippet:

Everyone who has even thought about exercising has heard the warnings about lactic acid. It builds up in your muscles. It is what makes your muscles burn. Its buildup is what makes your muscles tire and give out.

. . .

Lactic acid is actually a fuel, not a caustic waste product. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy. The reason trained athletes can perform so hard and so long is because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid.

. . .

Few scientists questioned this view, Dr. Brooks said. But, he said, he became interested in it in the 1960’s, when he was running track at Queens College and his coach told him that his performance was limited by a buildup of lactic acid.

When he graduated and began working on a Ph.D. in exercise physiology, he decided to study the lactic acid hypothesis for his dissertation.

“I gave rats radioactive lactic acid, and I found that they burned it faster than anything else I could give them,” Dr. Brooks said.

Hmmmmm.  So it looks like lactic acid is actually supposed to be there.  It helps you perform better.  So, here’s that link again – read why what you know about lactic acid is wrong.

Open source planetarium

Thanks goes to Bill, over at Dubious Quality, for pointing out Stellarium.  It is a free, open source planetarium.  Here’s a description from the site:

It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.

It is being used in planetarium projectors. Just set your coordinates and go.

Screen shots and additional information are available at the site.  The software is currently at release 0.8.0, so expect some bugs, but as with most open source projects past 0.1.0, there are likely not many or very minor.

Measuring the earth’s magnetic field

Sometimes, you can’t blame every worldly problem on President Bush. In this instance, scientists have known the earth’s magnetic field has weakened approximately 5% per century since 1840. What hasn’t been known is the change in times prior to that, because accurate records did not seem to exist. Recently, however, researchers have been using the log books from Captain Cook’s Pacific Ocean voyage to determine earlier fields states. And it looks like the field didn’t change much at that time.

So the changes are recent. At least, in geological terms. But not recent enough to blame it all on the current administration. And in the end, the weakening looks to be coming from the southern pole via patches of reverse magnetic flux – and I’m sure President Bush doesn’t have a machine to make that happen.

The modeling of historical magnetic data started in the early 1980’s by study team member David Gubbins, a researcher from University of Leeds in the United Kingdom.

Gubbins and colleagues started with readily available data like those in the logs of famed English sailor and explorer, James Cook.

“[We then] progressed to searching archives in Europe, including finding 50,000 ‘lost’ 18th century measurements in the East India Company Archives in London,” Gubbins told LiveScience.

The whole process of figuring this out sounds fascinating to me. But I’m a big geek that way.

Gigabyte g-Smart i

(via TechEBlog)
Normally, I don’t give a rip about new cell phones – at least, not enough to bother posting or talking much about them. This phone, however, looks pretty interesting to me. The Gigabyte g-Smart i is a clone of the Nokia 6270.  And it’s a phone I actually would like to have.i_phone_1.jpg

Here’s a Nokia 6270 clone done right. The g-Smart i features a 2.1-megapixel camera, MiniSD card slot, 2.4-inch TFT touch screen display, FM tuner, GPS navigation system (optional), TV tuner (optional), and support for a host of audio/video files (MP3/MPEG-4/3GPP/WMV). Plus, it’s powered by Windows Mobile 5.0. This phone measures just 19.8mm thin and weighs 130g. No word yet on pricing and availability.
