FM Radio could interfere with television broadcast channels 5 and 6, or aircraft navigation, since they're right next to each other!

AM Radio could interfere with aircraft beacons, since they're right next to each other!

Please. We've been allocating spectrum for things for a long time. Interference can be monitored and controlled. Do you really think that mobile telephone companies would put up with broadcasters puking all over their spectrum? Or vice versa? Or either putting up with amateur radio interference?

Or, perhaps worst of all, do you think the Hams would put up with someone interfering with their spectrum? They can triangulate secret government projects accidentally using their shortwave spectrum.

Yes, interference happens from all sorts of places. You'll likely find that devices in your adjacent spectrum are less likely to interfere than other sources of interference.

Should I Learn To Program iOS Or Android Devices? 403

Posted by timothy from the go-straight-for-neural-implants dept.
HW_Hack writes "In my early career in the '90s I had a hardware tech degree, but also a strong interest in software. I completed software courses in assembly, Pascal, HTML, and C as I prepped for a CS degree. I then got my chance to do hardware design for a major US firm and went that direction for a good 18-year career. I now work in a good sized school district doing IT support work at a large high school. I plan to revive my programming skills this winter so I can write apps for the flood of mobile devices. I am very much platform / OS agnostic and I support on any one day OS X, XP, Win 7, Linux servers, and now iOS as we pilot iPads in our school. My question focuses on three topics: Which programming environment (iOS or Android) is easier to jump into from a technical perspective / number of languages needed to master? Which one has a better SDK ecosystem of documentation, programmer support, and developer community(s)? Where is the market and the money going? I do not expect to get rich doing this, but with my insights into K12 needs I hope I can write effective apps for that market."

Tracking Down Wi-Fi Interference? 499

Posted by kdawson from the hello-fcc-i'd-like-to-report-hello?-hello? dept.
Nicros writes "Almost every evening, between 8:30 and 10:00, my Wi-Fi just dies. This, in itself, could be explained by a crappy Wi-Fi source or some hardware failure, except that I know both of my neighbors are experiencing the same loss of signal at the same time. While the Wi-Fi is down, the LAN is OK, and anything plugged into Cat5 can access the Internet just fine. One possibility comes to mind — perhaps some other neighbor arrives home and turns on their router from 8:30 to 10:00? And something in their signal is hosing our Wi-Fi? I have tried looking around for software to help identify the source of interference, but either the programs are ridiculously expensive for a home user, or else my card (Intel Link 1000 BGN) isn't supported. (Netstumbler is an example of the latter.) Any suggestions on how I can track this down?"

X Prize Foundation Wants AI Physician On Every Smartphone 245

Posted by Soulskill from the universal-health-care dept.
kkleiner writes "One of the exciting ideas being tossed around recently at the X Prize Foundation is the creation of an Artificial Intelligence physician that you could access from your smartphone. Want to know if that rash on your leg is poison ivy or smallpox? Take a photo of it with your phone and ask the AI. The possibilities are enormous, especially for the billion plus people around the world who live more than a few hours' walk or drive from the nearest doctor." This is one of four X Prizes in planning for the future. The other three are for an AI automobile driver, organ generation through stem cell use, and a deep sea submersible capable of exploring the sea floor.

Why No Billion-Dollar Open Source Companies? 487

Posted by Soulskill from the free-as-in-give-us-money dept.
Glyn Moody writes "If open source is such a success, why aren't there any billion-dollar turnover open source companies? A recent briefing by Red Hat's CEO, Jim Whitehurst, to a group of journalists may provide an answer. Asked why Red Hat wasn't yet a $5 billion company, as he suggested it would be one day, he said getting Red Hat to $5 billion meant 'replacing $50 billion of revenue' currently enjoyed by traditional computer companies. If, as is likely, that's generally true for open source companies, it means they will need to displace around $10 billion of proprietary business in order to achieve a billion-dollar turnover. Few are likely to do that. Perhaps it's time for managers of open source startups to stop chasing the billion-dollar dream. If they don't, they will set unrealistic ambitions for themselves, disappoint their investors, and allow opponents of free software to paint one of its defining successes — saving money — as a failure."

Stanford Robot Car Capable of Slide Parking 265

Posted by samzenpus from the no-human-would-drift-like-that dept.
kkleiner writes "Stanford's Junior, the robot car that took second place at DARPA's Grand Challenge in 2007, has learned how to perform a tire-squealing 180-degree spin into a skin-tight parking space. Similar to a James Bond action scene, the maneuver is impressive and would be extremely difficult for a human to pull off. We won't be handing the keys over to robot cars anytime soon, but Stanford shows us that at least for some driving tasks robot cars can already meet or even exceed human ability."

No 64 bit architecture now... I'll bet anyone they won't have any 64 bit products by 2011.

I guess you could stick a Coretex A9 in a box and call it a server, just like you can stick an Atom in a box and call it a server. At least the atom would support large address spaces.

Best Seating Arrangement For a Team of Developers? 520

Posted by timothy from the corner-office-round-table dept.
TekNullOG writes "I was given the job to prepare the logistics involved with moving our office. At the same time my bosses asked me to look into buying new desks for a small team of four developers and to consider if it could benefit the team to sit at a round table. In many offices and departments it increases productivity and makes collaboration easy. However, I am concerned that putting developers around a table could potentially be distracting consequently diminishing productivity by increasing coding errors. What are your thoughts?"

Simple CMS For Mixed Mac/Windows Team? 119

Posted by timothy from the fire-everyone-else-problem-solved dept.
Quasar Sera writes "I am looking for a content and/or project management solution for a marketing research team using both Macs and PCs. Ideally it would support document sharing, metadata/tags, search capabilities, revision control, and the ability to share documents easily with people from outside the team without any software installation or login required. It may be tricky to configure (since I will be doing that) but must be dead simple to use for the rest of the team. We rely mostly on Word, Powerpoint, and Excel (all in their native file formats) for our work, so it would be a large number of fairly small files. Any and all advice would be appreciated."

Fatal Flaw Discovered In Invisibility Cloaks 255

Posted by Soulskill from the you-cannae-fire-while-cloaked dept.
KentuckyFC writes "Carpet cloaks took the world by storm last year because they were the first devices to hide objects at optical frequencies. The idea is that a thin layer of dielectric material placed on a surface can make light look as if it is reflecting off the original surface. In other words, the layer is invisible and anything embedded within it is invisible too. This trick is like hiding something under a carpet, hence the name. Carpet cloaks are relatively easy to make because the dielectric material does not need to be specially constructed to steer light in special ways; physicists call this an isotropic material. Now a group at MIT has shown that isotropic carpet cloaks have a fatal flaw. When viewed at an angle, the carpets don't hide objects at all. Instead, they simply shift their position by about the same distance as they are high. So when viewed from an angle of 45 degrees, an object 0.2 units high is shifted to one side by a distance of 0.15 units, says the team. That's a serious limitation for carpet cloaks."
