Free online music services

Dear Readers,
I like to listen to music while I'm surfing the web(3 hours and up)and doing other non-computer things, reading, painting, etc. etc..
You will need a broadband connection to access these two sites, SORRY ! ! !
One of the FREE sites I love is www.pandora.com
it works on both Internet Explorer( IE ) and FireFox browsers(Opera always and sometimes FireFox has a tendency to crash on this site).
I use IE for only these types of sites and have put the security settings very high(I also have a software firewall and other layers of protection)and Flash Player plug-in.
Pandora is not for the musically clueless, if you only listen to pop, this site is not for you!
Pandora will ask you to register(very simple)and then the fun begins.
It will ask for a name of a musician that you like and it will serve up a track, then it will serve up artists similar to the main one.
I will give an example: create a station using Paul Desmond as the main musician and Pandora will serve you many similar types of musicians(bands).
You can create a second station using Carmen McRae as the main artist and mix the two stations for a very cool experience(you can create as many as 100 stations and you can mix as mush as you can). It is really good for exploring new musicians and music. The possibilities are very enormous.

The second Free site is:

www.live365.com

My cousin (Dr.)Emir Yusuf first brought this site to
my attention in 1999(?)but other things came up and the site went to the back of my mind.
live365 has a few very good Jazz and humor(comedy)stations and does not need your input...
A side note: you can create your own radio station for a very small price but if you are on adsl, the up-loading will be not practical(thanks to TurkTelekom's new owner's greed and incompetence. I thought privation meant competition and better service... I will rant on TurkTelekom on a different post).
Enjoy

The Truth About Digital Cameras

The Truth About Digital Cameras

As loyal Pogue’s Posts readers are no doubt aware, I’ve spent the last seven weeks in TV land, filming a first batch of six episodes of my new Discovery-network series, “It’s All Geek to Me.” It was an exhilarating, exhausting, enlightening journey. Someday when we’re all together, I’ll tell you about it.

Actually, I’ll tell you about one thing right now. We did an episode on digital cameras. Part of the fun involved visiting a couple of big electronics stores, posing as somebody who didn’t know much about cameras, and, later, commenting on what they told me.

The clerks at one store recognized me. The guy at the other store had no clue that I’m a tech writer. Both of them were surprisingly frank, pointing out, for example, that five megapixels is plenty for prints up to smallish poster size.

Now, every time I write that, I hear from furious or baffled readers. “I don’t get it,” wrote one. “A ten-megapixel camera produces photos about 3640 pixels wide–enough to make a 12-inch print at 300 dpi (dots per inch) on a good printer. Sure, you can go lower, but quality is sacrificed; you can’t make an 11×14 print, let alone anything bigger.”

I have to say, the math sounds right. But I also have to say that he’s wrong.

On the show, we did a test. We blew up a photograph to 16 x 24 inches at a professional photo lab. One print had 13-megapixel resolution; one had 8; the third had 5. Same exact photo, down-rezzed twice, all three printed at the same poster size. I wanted to hang them all on a wall in Times Square and challenge passersby to see if they could tell the difference.

Even the technician at the photo lab told me that I was crazy, that there’d be a huge difference between 5 megapixels and 13.
I’m prepared to give away the punch line of this segment, because hey—the show doesn’t air till February, and you’ll have forgotten all about what you read here today, right?

Anyway, we ran the test for about 45 minutes. Dozens of people stopped to take the test; a little crowd gathered. About 95 percent of the volunteers gave up, announcing that there was no possible way to tell the difference, even when mashing their faces right up against the prints. A handful of them attempted guesses—but were wrong. Only one person correctly ranked the prints in megapixel order, although (a) she was a photography professor, and (b) I believe she just got lucky.

I’m telling you, there was NO DIFFERENCE.

This post is going to get a lot of people riled up, I know, because in THEORY, you should be able to see a difference. But you can’t.

And I’m hoping this little test can save you some bucks the next time you’re shopping for a camera.

X-Drive is Back..(FREE online 5 gigs of storage)

X-Drive is Back..(FREE online 5 gigs of storage)
X-Drive was bought by AOL and is one of the free
services(I encourage you to check-out the others( http://www.aol.com )) other are email, IM, Journal(blog).....(if you have a AOL account log in with your screen name and password). if not, getting one is very easy.
For the computer clueless get someone to help-out.
for now I am testing it out with my nephews and will give a full review in a few months.
you will need Browsers: IE6(or 7) or Firefox 1.5 and up,
AOL ver. 8.0 and above, and BROADBAND connection(I have adsl 256/64 and it is slow to upload)
the Xdrive Desktop for windows software did not work with my system(windows 98SE) but it works fine with firefox Ver.1.5XX.
Its good for sharing big files and collaborating on projects.
also a good idea is to upload photos and music files so you
can access them anywhere and still keep them private(also
free's up some hard disk space).
it is worth a try.

p.s. info:
Platforms:
Windows® NT4/2000/XP(works with windows 98se)

Liberating iPods

Liberating iPods in Cambridge
Tuesday November 07, 2006 (06:00 PM GMT)
By: Benjamin Mako Hill

Last month, the MIT Media Lab Computing Counter Culture Group and the Harvard Free Culture Group held an "iPod Liberation event" -- a RockBox and iPodLinux "installfest" for Apple iPods. The event was held as a response to the fact that Apple installs iPods with an operating system -- a "firmware" -- that conflicts with the ideals of free and open source software and free culture and treats users parternalistically and adversarially. During the event, dubbed iRony, users were walked through the process of installing flexible and featureful free/open source software firmware -- without DRM -- onto their digital audio players

With nearly 70 million iPods and more than a billion iTunes songs sold, Apple has become the single largest vendor of DRM (digital rights/restrictions management) equipped technology and DRM-encumbered music. As a result, Apple was one of the first and most important targets of the Defective by Design anti-DRM campaign. Apple's critics have focused on the way that Apple privileges its own products, technologies, and services on the iPod. While Apple's stated goal of simplicity might suggest a hard drive interface onto which one could simply drag music and play, iPod users must go through iTunes, which obscures the file names and locations of the user's files on the iPod's hard drive. Users cannot easily move songs from an iPod onto another computer or iPod. By default, only a single "home" computer can extract files. Furthermore, Apple intentionally blocks integration between iPod and third-party software and music formats.

Most egregiously in the eyes of some digital freedom advocates, iPods have become the single most important vehicle for DRM -- greatly restricting music lovers' ability to share or control their music. Of course, Apple supports only its own DRM format -- an action that has been the subject of parliamentary discussion in France and grumbling globally. Similarly, Apple has refused to support popular patent- and royalty-free file formats such as OGG Vorbis and FLAC, placing owners of large FLAC and Vorbis collections out in the cold. Finally, many people want to use their iPods for more than music and video consumption, but Apple refuses to entertain these possibilities or to let users write or install software onto their iPod.

iPods have become a symbol of everything that free and open source software and free culture advocates oppose: iPods may belong to their owner, but they do what Apple and the music industry says. Your iPod may be yours, but it is outside of your control.

Breaking iPod's chains

To date, most protests critiquing Apple have been designed to keep consumers from buying more iPods, music from iTunes, and other Apple products. While a successful economic boycott is an excellent tactic, there is no place in it for the tens of millions of people who already have iPods. An alternative -- free and open source firmware -- can provide a solution to each of the issues described above, a way to return control of iPods to their users, and a way to involve the large number of people who already have iPods. The iPodLinux and RockBox projects offer two such firmwares.

iPodLinux aimed to address the issues presented by Apple's restrictive firmware by porting a version of ucLinux, a version of Linux designed to run on embedded systems, to the iPod. Additionally, iPodLinux hackers wrote a piece of software called Podzilla that mimics the interface and features of the familiar Apple firmware while allowing users to improve and customize it. For example, iPodLinux can run games (such as chess, solitaire, and Doom) or applications (such as calculators and music composition software) that were unavailable in the Apple iPod software. The iPodLinux project has been growing for more than two years and has been ported to nearly every generation of the iPod.

More recently, hackers have ported RockBox, a firmware written originally for the Archos Jukebox player, to a growing list of later generation iPods. RockBox can also run custom software and does not require any additional software (a la iTunes) to copy files onto or off an iPod. Additionally, it can play music encoded in MP3, FLAC, and OGG Vorbis out of the box. As one might expect, RockBox (like iPodLinux) does not provide support for DRMed formats. (NewsForge wrote about installing RockBox on an iPod earlier this year.)

However, while RockBox and iPodLinux have created interfaces similar to the iPod's default software and have become extremely easy to use for most people, both have been difficult to install for all but the most seasoned geeks. Even with new installers that automate much of the process, the act of "overwriting a boot loader" on an iPod remains an insurmountably frightening barrier for many would-be users of custom firmware.

For this reason, several free software and free culture advocates in the Boston area borrowed the idea of an "installfest" from the GNU/Linux community as a way of introducing users to alternative iPod firmware. Installfests became popular in the '90s, when GNU/Linux distributions were becoming increasingly easy to use but installation remained a prohibitively high barrier to entry -- installing GNU/Linux frequently required compiling a custom kernel and more. Even with extensive online documentation, the difficult installation process for most GNU/Linux distributions kept many interested users away. Installfests were embraced by Linux user groups as a way of both helping new users over the initial installation hump and helping introduce users into a support community of local enthusiasts.

Free and open source software on embedded systems and digital audio players is at a similar point in development to where free and open source software on desktop workstations was a decade ago. RockBox and iPod Linux are far from bug-free or feature-complete, but are reasonably stable. Most importantly, the greatest barrier to installation is the lack of tools and installers (in the case of RockBox) and the fear of screwing up and rendering a digital audio player inoperable ("bricking" a device in the community vernacular). In addition to building community, an install party can give iPod users access to more experienced users who can install alternate firmware on their player and to get a running start with their new firmware.

The iRony event

iRony was billed as an install party or an "iPod Liberation event" and garnered mention in the local press in the week leading up to the event. The event was organized by a broad group of people interested in free culture, including members of MIT, Harvard, Northeastern, and Emerson universities.

The event was open the public, advertised primarily online, but also mentioned in the local press, who were eager to report on any opposition to the ubiquitous Apple devices. Held in the MIT Media Lab in Cambridge, Mass., the event attracted more than 50 attendees and several dozen iPods to be liberated.

Organizers set up laptops running Ubuntu GNU/Linux, Mac OS X, and Windows XP at the center of the room. iPod users brought their players to experienced users, who would determine the generation of the iPod and the current partition format, and inquire about the user's needs. Together they would decide on a firmware (RockBox, iPodLinux, or both) and walk through the process of installation. Meanwhile, others looked on to watch the process and learn how it was done. RockBox was installed on the majority of the iPods with great success.

In addition to iPod installation, the organizers invited users to play music on a large stereo system using their newly liberated music players. The vast majority of participants left with liberated iPods and had a great time. A definitive tally of iPods liberated proved evasive, but it was more than 40.

Education

Ultimately, the goal of an iPod liberation event is education: education about software freedom, education about DRM, education about using RockBox and iPodLinux. As a result, it is communication, and not technology, that should be central. It's a good rule of thumb to spend more time talking than you think is necessary. Before an iPod is installed, make sure that every users knows:
The process: Make sure that users understand what your installing on their iPods and roughly how you are going to do it before you begin.
The point: Every user should want RockBox and should have some idea of what it's going to let them do. They won't take advantage of something they don't understand. Help them understand the DRM angle. At iRony, one user bought an iPod for the party. It is important to help these users understand that this is not something we can continue to support.
The risks: Ensure that each user has backups and is comfortable with the risks involved in installing alternate firmware.
The drawbacks: Reduced battery life and increased crashes while in RockBox are likely, and loss of iTunes DRM-encumbered music is a sure thing.

After installation, organizers should work with users to ensure that they understand a variety of issues around the maintenance and support of their new firmware. Since much of this information will be repeated to every user -- and because one can only absorb so much -- it might be a good idea to create a flier to hand out at the event. In particular, organizers should:
Ensure that users know how to boot back to the Apple firmware (this usually entails pressing menu when the iPod reboots).
Make sure that users know how to reboot their iPod if and when it freezes.
Ensure that users understand how to upgrade RockBox. You're installing daily builds, and users will want to upgrade to the latest stuff.
Ensure that users know where to look for help. Make sure they know how to find the RockBox or iPodLinux wiki and that they have contacts in your group if they have serious problems.

Long term energy policy

The future holds two major
problems, high population and
energy..
if we do not address these now with wiger we will enter a cycle of upheaval(we may be in the start of this cycle).
The best is a mixed bag of renewable(solar, wind, sea, geothermal....), new, very efficient power usages systems and a new economic model based on conservation.
a strict population management system has to be formulated.

Generating Power From Kites
By Nicole Martinelli
02:00 AM Oct, 10, 2006

Researchers in Italy have high hopes for a new wind-power generator that resembles a backyard drying rack on steroids. Despite its appearance, the Kite Wind Generator, or KiteGen for short, could produce as much energy as a nuclear power plant.

Here's how it works: When wind hits the KiteGen, kites spring from funnels at the ends of poles. For each kite, winches release a pair of high-resistance cables to control direction and angle. The kites are not your Saturday-afternoon park variety but similar to those used for kite surfing -- light and ultra-resistant, capable of reaching an altitude of 2,000 meters.

KiteGen's core is set in motion by the twirl of the kites; the rotation activates large alternators producing current. A control system on autopilot optimizes the flight pattern to maximize the juice produced as it sails on night and day. A radar system can redirect kites within seconds in case of any interference: oncoming helicopters, for example. Or small planes or even single birds.

Research by Sequoia Automation, the small company near Turin heading the project, estimates that KiteGen could churn out one gigawatt of power at a cost of just 1.5 euros per megawatt hour. That's nearly 30 times less than the average cost in Europe of 43 euros per megawatt hour.

Proponents say other plusses of the merry-go-round generator are the contained cost of 360,000 euros and limited amount of space needed. Even with a modest diameter of about 320 feet (100 meters), they estimate KiteGen can produce half a gigawatt of energy. Emulators for the scalable project envision a 2,000 meter-version that would generate 5 gigawatts of power.

Fortunately for Sequoia, whose core business is sensor design and industrial automation, employees take work home with them. Massimo Ippolito, head of R&D, inspired by his weekend hobbies of hang gliding and kite surfing, started mulling the idea that would become KiteGen. Six years and seven patents later, he's leading a team of 20 to construct the giant, energy-creating carousel. The team expects it to be up and running in about two years.

"It's been called revolutionary, but I see it as part of a new energy future," said Ippolito, 48. "With the right mix of photovoltaic, solar thermal power, plus wind power from KiteGen, we can try to meet the needs for rising global electricity consumption."

Ippolito hopes that because of the amount of energy produced for its compact size, KiteGen will become the wind generator of choice, standing head and shoulders over similar recent projects such as glider generators and windmills.

So far, things look promising. A small-scale portable version called MobileGen (a single kite trailing from a flat-bed truck) made good headway when test-launched in August. It generated energy -- and a list of improvements. Researchers were "really charged up," Ippolito said, to see the generator in action.

It may not be completely smooth sailing for KiteGen, though. Some approve the concept but have adopted a wait-and-see attitude.

"It's a fascinating project, for the amount of power it promises and the low cost," said Luciano Pirazzi, who studies renewable energy for Italian government agency ENEA. "But -- and there are a series of buts -- it is still basically a concept on the drawing board. Feasibility has to be proven."

Outstanding questions about such a generator include location and possible bureaucratic headaches over permits for air space. Current speculation is that KiteGen may soar above the former Trino Vercellese nuclear power plant, already a no-fly zone, in the region.

Italy has until 2010 to bump up renewable energy to 22 percent of total electricity supply, in order to meet the EU Renewable Energy Directive. Wind power is a key component and competition from national and foreign enterprise is expected to be stiff.

Naysayers probably won't knock the wind entirely out of KiteGen's sails. Sequoia was honored earlier this year with a 2006 World Renewable Energy Award for its work on KiteGen.

KiteGen also managed to convince Turin utility company AEM to cover 40 percent of expenses for the prototype and sign on as technical partner. It was the first time the utility, which is a long way from Italy's prime windmill coastal zones, has invested in such a project.

"When you first see it you have to smile, because it's a bit funny looking," said Andrea Ponta, an engineer at AEM. "But the more you examine it, you see the idea is sound and the technology is already available."
