"Terrorist" Lyrics Land High Schooler In Jail 573

Posted by timothy from the now-for-aesthetic-offenses-maybe dept.
An anonymous reader writes "A Methusen, Mass. high schooler, who goes by the rapper name 'Cammy Dee' has been arrested after posting lyrics that police felt were 'communicating terrorist threats.' This wouldn't be the first time rap lyrics were investigated, but if formally charged for 'communicating terrorist threats' this would a set a chilling low bar for terrorist investigations."

Help Me Get My Math Back? 467

Posted by kdawson from the we-can-forget-it-for-you-wholesale dept.
nwm writes "I am trying to refresh my math skills back to the point that I can take college-level statistics and calculus courses. I took everything through AP calculus in high school, had my butt kicked by college calculus, and dropped out shortly thereafter. Twenty+ years later, I need to take a few math courses to wrap up a degree. I've dug around some and found a few sites with useful information, but I'm hoping the Slashdot crowd can offer some good resources — sites, books, programs, online tutors, etc. I really don't want to have to take a series of algebra-geometry-trig 'pre-college' level courses (each at full cost and each a semester long) just to warm my brain up; I'd much rather find some resources, review, cram, and take the placement test with some confidence. Any suggestions?"

Order now and you more likely than not will have your CD set, T-shirt or other cool stuff before the official release date. You get the chance to support the most important free software project on the planet, and get your hands on some cool playables and wearables early.

Best Smartphone Plan Covering US and Canada? 199

Posted by timothy from the move-to-regular-scotia dept.
j00bhaka writes "I am a US citizen attending university in Nova Scotia, Canada. I currently have the Verizon America and Canada plan (also known as the North American plan). My bill is currently around $80-$100 per month. I chose this for a couple reasons. One, I have had my number for about 7 years. Two, I do not permanently live in Canada. I live in Canada for 8 months out of the year at school, then travel home for the summer months. Either way, I would be dealing with international roaming without having both countries in my plan. Currently, I obviously don't have a smartphone. Through Verizon, I could purchase one, and add their international unlimited data plan on top of my (already) hefty phone bill. I have looked into Telus and Rogers here in Canada and cannot find anything better. As a student, my budget is obviously limited. Is there any way to reasonably have (and utilize) a smartphone while I am living in both countries? If so, what do you suggest I do?"

Insomniacs, the Phantoms of the Internet 234

Posted by kdawson from the knitting-the-raveled-sleeve-of-care dept.
theodp writes "Ever since she was a toddler, freelance writer Lily Burana has been a Stay Up Late kind of girl. When her kindergarten teacher asked students 'What time do you go to bed?,' young Lily felt compelled to lie rather than rat out her own mother by saying, 'Oh, between midnight and 1 a.m.' She still suffers from insomnia, but has discovered that Facebook is the Promised Land for the awake and alone. She finds comfort in the company of others who, like her, live counter to the conventional rhythm of a sunny-day world."

What Objects To Focus On For School Astronomy? 377

Posted by timothy from the satellites-and-moonbeams dept.
IceDiver writes "I am a teacher in a small rural school. My Grade 9 students are doing a unit on astronomy this spring. I have access to a 4" telescope, and would like to give my students a chance to use it. We will probably only be able to attempt observations on a couple of nights because of weather and time restrictions. I am as new to telescope use as my students, so I have no idea what objects would look good through a 4" lens. What observations should I attempt to have my students make? In other words, how can I make best use of my limited equipment and time to give my students the best experience possible?"

How To Spread Word About My FOSS Project? 244

Posted by timothy from the luck-plays-a-role dept.
An anonymous reader writes "I'm in a bit of a bind with an open source web software project of mine. It's a very small project that I've been developing for over three years. By now it's got a promising feature set, but very few users and virtually no community around it. The problem is that people I have asked to try it refuse to do so because it doesn't have a thriving community. It's an infinite loop: without users, we won't have a community, and without a community, users aren't coming. So, Slashdot, my question is: how can I build a community and help get the word out about a project led by 2 people and with only 5-6 regulars on our forum and IRC?"

Researchers Pooh-Pooh Algae-Based Biofuel 238

Posted by timothy from the feed-it-pooh-pooh-undies dept.
Julie188 writes "Researchers from the University of Virginia have found that current algae biofuel production methods consume more energy, have higher greenhouse gas emissions and use more water than other biofuel sources, such as switchgrass, canola and corn. The researchers suggest these problems can be overcome by situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential algae nutrients that otherwise need to come from petroleum."

Comment Only one interface. (Score 1) 376

Any one those cheap Linksys / D-Link routers will be limited to 30-40mbs because there is really only one 100mbps MII interface to the CPU. The uplink and LAN interfaces are separated out through VLANing with the built-in switch. So basically, all traffic has to go over the same 100mbps interface *twice*, thus halving the throughput. You can get an old Sun Netra X1 with dual NICs off of eBay for like $50.

Machine Condenses Drinking Water Out of Thin Air 438

Posted by timothy from the LED-bulbs-or-klieg-light-specials? dept.
longacre writes "A new $1,200 machine that uses the same amount of power as three light bulbs promises to condense drinkable water out of the air. On display at Wired Magazine's annual tech showcase, the WaterMill 'looks like a giant golf ball that has been chopped in half: it is about 3ft in diameter, made of white plastic, and is attached to the wall. It works by drawing air through filters to remove dust and particles, then cooling it to just below the temperature at which dew forms. The condensed water is passed through a self-sterilising chamber that uses microbe-busting UV light to eradicate any possibility of Legionnaires' disease or other infections. Finally, it is filtered and passed through a pipe to the owner's fridge or kitchen tap.'"
