A New Way To Produce Hydrogen 204

Iddo Genuth writes "Scientists at Pennsylvania State University and Virginia Commonwealth University are producing hydrogen by exposing clusters of aluminum atoms to water. Rather than relying on the electronic properties of the aluminum, this new process depends on the geometric distribution of atoms within the clusters. It requires the presence of 'Lewis acids' and 'Lewis bases' in those atoms (water can act as either). Unlike most hydrogen production processes, this method can be used at room temperature and doesn't require the application of heat or electricity to work. The researchers experimented with a variety of different aluminum cluster patterns, discovering three that result in hydrogen production."

and i've worked out why:

i try write too fast!

when i type, i'm putting out 60-70 words per min, when i'm handwriting, its way way down, but i keep trying to go faster.

i've notice when i slow down and concentrate on the writing part, less what i'm writing, it shapes back up again to something more like i would have put out 15 yrs ago before i started sitting in front of a keyboard, and back in the day my handwriting was actually pretty decent by most standards.

its the same deal on paper as it is on the whiteboard - slow it down and it comes back to what it used to be

dont we wish A/C's would grow a pair and put their names to whiney slapper comments like this?

whilst the set-up was knocked down by rts008 ( boom boom! ), if A/C had a fucking clue, they may have picked up on the :wq part - i actually voted vi, but find gedit quite useful for many straight up text purposes.

actually, this part of my original rebuttal was in relation to the troll's assertion that everyone had ditched java...

there is a time and a place for everything, but if your penny-pinched cheap ass hardware cant run the software, then where do you lay the blame?

certainly every mobile phone i've had in the last 5 years has run java applications which are responsive and stable ( i concede this is usually one golf game per phone, but still...), and i dont go for the top of the line bright and shineys...

And to cap it all, the JVM is utterly non-portable, so much so that barely 1/4 of the highly varied boxes in my computer room complete the installation cleanly

perhaps you need to take the 'how to double-click install.exe' course again?

Now it's racks of big ass servers or blades groaning under badly designed layers and layers of Java 'middleware'

so your premis here is the problem is the language/platform rather than the design at fault?

If you have insane amounts of CPU and memory to throw at it to cover up the slowness

either you need to replace the tandy coco you mention later as your primary pc, or you could actually _try_ it before you bag it. ( trying it again after 1997 might also be an idea..)

Must have missed it.

that tends to happen when you have HASUB* syndrome. it happens, dont worry about it. you probably havent noticed a lot of stuff.

.. some rant about java and vista bloat related to java desktop. and then brings solaris and mac into it. pfft.

yawn.

No, you notice when a small app starts sucking up all available memory. Java sucks memory so hard GNOME starts looking lean in comparison

i can malloc my way into something that smells the same in c too.. only in java you're less likely to leak.

hey actually put players on shelves that take upwards of two minutes to go from tray close to anything useful appearing on the display

huh? i drop blu-ray disks into my ps3 and its playing within a few seconds. you're smoking crack.

I've got a cheap crappy basic cell phone. You can almost see individual pixels draw on the darned thing...

unless you run an application on your cheap crappy phone, you're probably looking at just the cheapness and the crappiness of the phone, not java.

i think what you really meant in the above post was more along the lines of 'get off my lawn'.

i know this is slashdot, but occasional fact checking really cant hurt if you're going to go on a raving rant about your hatred of specific technologies.

you're confusing java applets circa 1997 with the java platform.

take a look through the it job listings and see how much java comes up.

much, if not most, server side *enterprise* work is done in java, which is a mature, robust, reliable, performant and scalable platform for which there are myriad commercial and open source libraries to give any project a great set of building blocks and frameworks on which to build.

i check out language du jour a couple times a year, and every time it reaffirms java's benefits.

the problem with applets is they were generally pretty hacky, but there are some good ones out there.

( check out the yahoo games website - my wife has been addicted to literati for years, and its a nice little java applet ).

java on the desktop has a place too, however its the same set of rules for design and structure as applets: done well, nobody would know/care what language its written in, but done poorly without care for threading models and it'll quickly turn into a steaming pile.

then theres j2me, and i'd wager if you have any tivo type device, or even set-top box for your cable service, or blu-ray player, or most mobile phones these days, then you have java working for you there too.

not that i'm arguing for applets by any means, but the more people spread the same old rants as above, the more i'm inclined to correct them.

iPhone App Pricing Limits Developers 437

HardYakka writes "According to this post in the Fortune blog, the iTunes app store has been a boon for users but some developers are saying the number of free and 99 cent apps make it difficult for developers to create complex, higher priced apps. Craig Hockenberry of Iconfactory says the iPhone may never get its killer app like the spreadsheet was for the Mac. If Apple does not do something, the store will be left with only ring tones and simple games. Some are suggesting that overpaid developers are the problem and the recession will soon lower the wages and costs for complex apps."
