BRK.B shares currently trade around US$160ish/share. The dividend equivalent to selling even a single share would incur $24 in taxes (15%), and the transaction fee for a discount broker is around $7 or $8. So unless the shares have t

So sell some shares. It can be better than a dividend for tax purposes. This is a common topic at the annual meetings, and Buffett has addressed it in detail before: http://www.fool.com/retirement/2016/12/02&#

Keep in mind that 700 b/s is an extremely low bitrate. I worked on Opus, which bottoms out at around 6000 b/s. A typical IP+UDP+RTP packet has 40 bytes of headers, which with 40 ms frames is 8000 b/s of overhead. Cell netwo

It's really hard to know when a patent will expire or has expired. Figuring out the relevant priority date is complicated, especially when foreign applications are involved. We're still in the region where you have to worry about

We asked some folks at Oracle about this, and my understanding is that this fee is imposed by the vendor providing the Opus implementation for their DSPs. Oracle is just passing on this cost. A specific implementation may, of course, includ
