I doubt my crappy speakers can emit anything in that frequency. Even then, my phone's mic is not probably up to the task.

Besides, I'm sure those who are worried could buy/build a filter to remove audio in that frequency.

Malware is also served up through compromised ad services. So going to legit sites can still lead to a phone getting malware. Mobile ad networks are usually worse than the regular web.

I suggest after wiping the phone, to install a good adblocker and to use a browser that blocks ads by default. I personally like using the Ghostery browser.

If you are also worried, make sure that you have it set NOT to allow installation of apps from unknown sources.

I wonder how much worse traffic congestion will be as people find it cheaper to let their cars drive around all day than pay for parking? Or park anywhere it is free to do so.

Perhaps the associated press should play a part in foia requests by making requests on behalf of member news outlets. Just set aside a fund for paying for the requests.

The problem isn't the software, but how people are using it. Banning Power Point won't fix bad end users. They will just find a different way to give crappy presentations.

Perhaps a better approach is bundle or create software that helps people create presentations from the script on up, and perhaps the software should have one presentation the audience sees and one the presenter sees full of more info or a complete script.

The big misconception people have about young people and technology is the idea that kids know how technology works or how to use it.They just assume stuff will work and when it doesn't they don't know what to do.

They need to learn the basics:
File formats/extensions
Drives (C, D, E...)
Folders and the most basic of folder structures
How to navigate to different drives/folders/etc.
some basic troubleshooting skills

I would say critical thinking skills and a genuine sense of curiosity are the things they need most.

Not only are many who are looking for a job already employed, but job sites are a treasure trove of personal information. People post resumes with nearly everything but their ssn. They also give out phone numbers and email address of people they know.

And if you know people are looking for a job, what kinds of jobs, and can then build targeted phishing that looks like a job offer/application, get the person to give you their SSN and information, then sell it or use it.

It is also the customers that want dvds/blu-rays. For some (possibly many) it is actually MORE convenient to put a disc in the player than it is to hook up computer to the TV or set up the blu-ray player to connect to the internet. Also not everyone has a fast enough connection to stream video on par with a blu-ray disc or may have bandwidth limits that make streaming not as viable an option.

Plus there are probably dozens of trivial non-tech reasons why people like getting a disc. For example, they may like getting a physical thing they ordered in the mail or like the extra features and trailers that come on the DVD but are not streamed.

IT seems the few people making money from FOSS have done so by using the software both as a tool to provide a service and as a form of advertising.
