Submission + - Open Source Codec Encodes Voice Into Only 700 Bits Per Second (rowetel.com)

Bruce Perens writes: David Rowe VK5DGR has been working on ultra-low-bandwidth digital voice codecs for years, and his latest quest has been to come up with a digital codec that would compete well with single-sideband modulation used by ham contesters to score the longest-distance communications using HF radio. A new codec records clear, but not hi-fi, voice in 700 bits per second, that's 88 bytes per second. Connected to an already-existing Open Source digital modem, it might beat SSB.

Obviously there are other uses for recording voice at ultra-low-bandwidth. Many smartphones could record your voice for your entire life using their existing storage. A single IP packet could carry 15 seconds of speech. Ultra-low-bandwidth codecs don't help conventional VoIP, though. The payload size for low-latency voice is only a few bytes, and the packet overhead will be at least 10 times that size.

Comment Does it offload work to the IMAP server yet? (Score 2) 38

I've got several Cyrus IMAP hosted mailboxes with tens of thousands of messages in them.

Last time I tried Mutt it could only do "slurp all mailbox contents to local machine" Can Mutt offload searches to the IMAP server, fetch only 1 page of data at a time (not download all headers) etc yet?

It'd be nice for there to be competition besides Alpine.

Comment Re:Is negotiation a skill required for the job? (Score 1) 892

I disagree. I've regularly negotiated better salaries than my co-workers. In many cases, I've negotiated better salaries than my bosses. I can do this because I have a strong basis upon which to negotiate. I'm generally better at what I do than most of my co-workers. I don't say it to brag. But I am and I negotiate from that position: I deserve more because I'm better at it than the average person and I have the track record to back that up. Should I now be paid what the average guy is paid? I'm not going to want to work for a company that doesn't appreciate the value I bring to the job (unless, of course, the job is just really cool, in which case salary takes a back seat).

Comment Re:If you demand all your supporters be flawless.. (Score 1) 653

Jesus said nothing. Paul did comment on it, however, so Christians often use that as the basis of their new testament argument. Also the new covenant doesn't mean you completely ignore mosaic law, but I admit to being quite confounded by the distinction. Bottom line, though is that Jesus said to "love your neighbor as yourself." It's in two of the gospels. He didn't make exceptions for homosexuals. And Jesus DID comment on divorce (Matthew 19:9) and you don't see a lot of Christians denying services to remarried people whose original spouses didn't commit adultery.

Comment Religious hypocrisy (Score 0) 1168

The problem with all this hate disguised as religion is that it doesn't hold up. It's complete and utter hypocrisy. Homosexuality is called a sin in both Leviticus and 1 Corinthians. Leviticus and 1 Corinthians also say that tattoos are a sin. My wife and I attend an evangelical church in the south and it doesn't escape our attention that there are a great many congregants with tattoos. Especially those cute ankle and back of the neck ones... You don't see Christians up in arms about them getting married or refusing them service. In Matthew 19:9, Jesus said that a man who divorces his wife, except for adultery, and remarries is himself committing adultery. 1/3-1/2 of all divorces in the U.S. don't involve adultery, and yet do you see Christians refusing these people service or refusing the remarry them? Jesus said the second most important commandment was to "love your neighbor as yourself." It's quoted in two Gospels, Mark and Matthew. He didn't say there's an exception for homosexuals. In fact, he never said anything about homosexuals. The Christian right in this country reminds me of the Pharisees in the bible. Trying to interpret who God would judge and passing their own judgment instead of leaving the judgment to God and loving their neighbor, regardless of their neighbors sins because, after all, the bible tells us that we are all sinners.

De-escalating the Android Patent War 63

In 2011, a consortium formed from Microsoft, Apple, Sony, BlackBerry, and others spent $4.5 billion acquiring Nortel's patent portfolio, which contained a great deal of ammunition that could be used against Android. That threat has now been reduced. Today, 4,000 of the patents were purchased by a corporation called RPX, which has licensing agreements from Google, Cisco, and dozens more companies. [RPX is] a company that collects a bunch of patents with the goal of using those patents for member companies for defensive purposes. Even though RPX has generally been "good," the business model basically lives because of patent trolling. Its very existence is because of all the patent trolling and abuse out there. In this case, though, it's making sure that basically anyone can license these patents under FRAND (fair and reasonable, non-discriminatory) rates. The price being paid is approximately $900 million. While that article points out that this is considerably less than the $4.5 billion Microsoft and Apple paid originally, again, this is only 4,000 of the 6,000 patents, and you have to assume the 2,000 the other companies kept were the really valuable patents. In short, this is basically Google and Cisco (with some help from a few others) licensing these patents to stop the majority of the lawsuits -- while also making sure that others can pay in as well should they feel threatened. Of course, Microsoft, Apple and the others still have control over the really good patents they kept for themselves, rather than give to Rockstar. And the whole thing does nothing for innovation other than shift around some money.

In all seriousness, though, I think Sony ought to release the movie and I think everyone who believes in free speech ought to buy a ticket, whether they see it or not. Let's turn this movie into a blockbuster! That's the American thing to do! Well, at least back when Americans acted like Americans.

Comment Go see the movie (Score 1) 182

I wasn't planning on seeing the movie, but I'm going to see it if they release it now and I think ever American who believes in free speech ought to do what they can to make this movie into a blockbuster. You don't even have to watch it if you don't want to. Just buy a ticket. How better to show that free speech will not be run off by a bunch of hackers. Or are we going to tuck tail and run? Right now it's looking like tuck tail as movie theaters are pulling it and Sony might even pull it. How pathetic.

Comment Re:Only YEC denies it (Score 2, Interesting) 669

As someone who lives in the U.S. South (Arkansas), this is not the belief of most evangelicals. My wife is a devout Christian and our church is an evangelical church (though not like most that you're probably familiar with. Our church is very into being Christians and not so much talking about how Christian they are. They spend the vast majority of their money helping people in poverty while meeting in a Boys & Girls Club gym instead of building a real church.) But among the religious around here, there's very little belief in evolution or the big bang. That said, the local Christian university (John Brown University) has a pretty good evolutionary biology program. So there's some hope for the future, but not as much as I'd like. Science is definitely taking a back seat with evangelicals in the South. It's a pretty tragic state for the future of science in this country. The South certainly won't be contributing a lot to modern cosmology or evolutionary biology.
