Comment Project at USC (Score 1) 86

We have a project at USC that we've been working on which is similar but we show a sample of the individual tweets that were classified:
http://politics.twittersentiment.org/streams/
The system in the article doesn't show any of the data that they use to base the scores on, so it is effectively a black box. Also it lacks the entertainment value of seeing the sometimes funny twitter data. Also, ours is real time so it's interesting to watch during a debate.

Comment wow... maybe I don't want to delete my history (Score 1) 238

I just logged into www.google.com/history and saw my browsing history back to 2007. I understand some of the privacy concerns, but I actually found it interesting to see what webpages I went to 5 years ago. For me, the ability to look back into details of the past that may have left my conscious memory recall seems to outweigh the security concerns. Also, on the www.google.com/history page you can delete individual record items so if there's something IN PARTICULAR that you want to delete... hint, hint, nudge, nudge, say no more.
Book Reviews

Submission + - Thunderstruck the invention of wireless dramatized

Ferante125 writes: This book is a immersive trip into the early 1900's, where Marconi's sensational new wireless technology meets a sensational mystery. I enjoyed this book very much, which is why I felt like reviewing it, and I also thought it would be a relevant and entertaining book for slashdot's audience, which is why I'm reviewing it here (c.f. internet at sea http://ask.slashdot.org/article.pl?sid=09/01/13/1619201, which deals with some of the same issues, albeit in the book it is telegraphy at sea). This book was a gift from my brother Kurt for last year's Christmas, but i was busy so I didn't have time to read it right away. If it took me a long time to get around to start reading, it was quick to finish. It is a very engaging narrative that jumps between the story of Marconi, the infamous Italian inventor of radio, some of his rival inventors--in particular Oliver Joseph Lodge, whose interest in the occult sidetracked him from following up on his early wireless experiments, and Howley Harvey Crippen, a seller of patent medicine (like today's internet prescriptions) who has an overbearing wife that has mysteriously disappeared.

The mood of the book has a similar feel to "The Prestige" and Sherlock Holmes stories. Scientists are on the verge of revolutionary discoveries, but before the illumination of retrospect, people are dubious, superstitious, and opinionated. There are plenty of themes that seem applicable to our current time. There is the debate between science and engineering, wisdom and experience versus naive experimentation, Maxwellian professors versus the telegraph engineers. There are arguments about who is the originator of a discovery. Is invention the idea or following though and showing that it actually works and can be used practically? The scientists who may have actually first demonstrated wireless communication did not work on perfecting it because they did not think the signal would carry farther than sight, while Marconi thought that taller and more powerful antennae would enable longer range communication, and in the process realized the effects of the time of day and waves traveling over open sea. Another timely theme is proprietary versus open source. Marconi took great pains to maintain a monopoly on wireless telegraphy, but there was the problem of interference with competitors and nationalistic interests of Germany.

Another interesting aspect I saw is the relationships with women. Marconi does not have problems finding women because he's very rich and Italian, but he has a hard time keeping them because he's busy with his research and a bit asocial from being a boy-wonder. Crippen on the other hand, is a bit homely and is cheated and mistreated by his wannabe opera singer wife. He finally leaves her for his secretary, with whom he escapes by dressing her up as a boy. The relationships add to the story and though they are a tad exaggerated, they add to the sensationalism. The book's relationships are refreshingly dysfunctional and seem to cut out a lot of the typical Hollywood crap. As he is pursued as a suspect in his wife's disappearance, the wireless telegraphy between boats is instrumental in the search. The public's fascination with the mystery and the wireless technology makes this the turning point in wireless' adoption. A friend to whom I lent the book remarked that this may have been the first high-speed pursuit, with boats and telegrams standing in for cars and television. Though the high-speed pursuit may be slower and lower-tech, it is none the less exciting and the book ends with a nice denouement.

Despite the lengthy bibliography at the back of the book, I found it hard to believe this book was non-fiction. I'm a big fan of historical fiction and I have no qualms about an author's right and obligation to entertain, but this book is both entertaining and also seems to be the result of lots of digging through historical records, court transcripts, and memoirs of Marconi's relatives. Some of the dialog in the book was even based on transcripts.

Though my review may have focused on the tech, I also think that this is a good book for others due to its historical and dramatic content.

Is the Line-in Jack On the Verge of Extinction? 411

SlashD0tter writes "Many older sound cards were shipped with line-out, microphone-in, and a line-in jacks. For years I've used such a line-in jack on an old Windows 2000 dinosaur desktop that I bought in 2000 (600 Mhz PIII) to capture the stereo audio signal from an old Technics receiver. I've used this arrangement to recover the audio from a slew of old vinyl LPs and even a few cassettes using some simple audio manipulating software from a small shop in Australia. I've noticed only recently, unfortunately, that all of the four laptops I've bought since then have omitted a line-in jack, forcing me to continue keeping this old desktop on life support. I've looked around for USB sound cards that include a line-in jack, but I haven't been too impressed by the selection. Is the line-in jack doomed to extinction, possibly due to lobbying from vested interests, or are there better thinking-outside-the-box alternatives available?"

Submission + - $99 Moby Tablet as textbook alternative (engadget.com) 1

Taco Cowboy writes: Marvell's Moby tablet will be an "always-on, high performance multimedia tablet" capable of full Flash support and 1080p HD playback and supporting WiFi, Bluetooth, FM radio, GPS and both Android and Windows Mobile platforms for maximum flexibility.

Marvell's Moby tablet could eliminate the need for students to buy and carry bound textbooks and an array of other tools.

Actual size and weight vary by configuration, but Marvell's ultra thin and light Moby tablet is expected to hold a full year's worth of books but weigh less than half of one typical textbook.

Music By Natural Selection 164

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

Microsoft Game Software Preps Soldiers For Battle 44

coondoggie writes "Soldiers may go into battle better prepared to handle equipment and with a greater knowledge of their surroundings after an intellectual property licensing deal Monday between Microsoft and Lockheed Martin that will deepen the defense giant's access to visual simulation technology. The intellectual property agreement between the two focuses on Microsoft ESP, a games-based visual simulation software platform for the PC."

The opium wars are not a good argument for a number of reasons: 1. Opium != marijuana in an important way. One is physically addictive and the other is not. 2. Opium was marketed into China so that foreign powers could profit. I think the opium war makes sense as an argument against fossil fuels as much as it does as an argument against the good herb.
