Comment I'm not an expert (Score 1) 291

But what if you saved both images in an uncompressed format (bmp?), then compressed them both using a lossless format (gzip?), and compared the file sizes...

Do it with a bunch of images, and I expect you'll discover that the low-quality-gzipped image will be smaller than the high-quality-gzipped image...

Maybe? *shrug*

Comment Re:Normal diesel engines work with vegetable oil (Score 3, Informative) 188

Those are far from the "only" problems... they are the easiest problems to detect. There are countless forums on the Internet that discuss all the finer points of running veg oil in diesel engines... use google if you want to find them to read all the nitty gritty details. General consensus is that running unprocessed veg oil most diesel engines will lead to coking over time, unless you heat the veg oil first. If you aren't extremely careful to remove all water from the oil, you can wear out the cylinder walls very quickly, too... and won't necessarily even notice a degradation in performance until it's too late. There are other problems that apply to specific models of diesel engines, too--you can't even run biodiesel in an '09 model year Volkswagen TDI engine without serious problems; I wouldn't even dream of trying straight VO.

Comment Re:No conversion needed (Score 2, Interesting) 188

Practically any veg oil *can* be used directly to power a diesel engine. But most diesel engines are not designed with such oils in mind, and therefor do not work well for extended periods of time with such oils. You risk damaging your engine if you run unmodified vegetable oil in most unmodified engines. This has been known for a century or so.

That's hardly "diesel oil" any more than other forms of vegetable oil are "diesel oil". It still needs to be converted to biodiesel to be safe for long-term use in a diesel engine. Of course it simplifies the oil extraction process greatly (usually done by pressing). You're going to get a lot of impurities (like water!) if you do what you suggest, too.

I remember similar doomsday stories when the 28.8kbps modem came out. "With such fast Internet access to homes, the backbones will now be overloaded!"

News flash... ISPs and Telcos know how to increase their bandwidth, too... it's not just the last mile that's getting faster and allowing people to do more and more frivolous things with their Internet connections.

Map Editor, Photoshop Tool Coming To Braid 44

Erik J writes "Braid creator Jonathon Blow has revealed that a map editor and image tool will be added to the popular puzzle game. First, though, Braid will receive a patch to fix some issues players have reported. Blow explains: 'After I get a new version out in a few days that fixes the problems some people are having, and when more people have played/finished the game, I am going to post some documentation for the editor. The way it works is you can make levels with the editor (up to a full game, potentially) and run that with -universe later... also a tool will be released that lets you take Photoshop files and import them into the game, if you want to put new graphics in your levels.' It is unclear if these capabilities are coming only to PC or to the Xbox 360 version as well."

Online Banking Customers Migrating To Lynx 220

Jibbler writes "Following the recent Pwn2Own competition, in which Firefox, IE8 and Safari all fell quickly to exploits, Netcraft has observed a surge in popularity of the text-based Lynx browser. Netcraft points out that Lynx supports the latest cryptographic ciphers, and at least one online banking site has seen Lynx usage overtake that of Internet Explorer and Firefox. To boost Lynx's excellent security history, Netcraft has even developed a version of its anti-phishing toolbar for Lynx."
