Bruce Perens writes "Codec2 is the Open Source ultra-low-bandwidth speech codec capable of encoding voice in 1200 Baud. FreeDV (freedv .org) is an HF (global-range radio) implementation that uses half the bandwidth of SSB, and without the noise. Here are three speeches about where it's going."

• Bruce Perens: FreeDV, Codec2, and HT of the Future (how we're building a software-defined walkie-talkie that's smarter than a smartphone), at the TAPR/ARRL Digital Communications Conference 2013. Blip.tv, YouTube
• Chris Testa on the .Whitebox handheld software-defined radio design that is the RF portion of HT of the Future, which was also shown at the TAPR conference.

Bios_Hakr points out an ironic use of the DMCA: for the second time, a video tutorial on fair use that Larry Lessig uploaded to YouTube has been muzzled. This time the sound has been pulled from the video; last time the video was taken off of YouTube. (Video and sound for the new "webside chat" can be experienced together on BlipTV.) Both times, Warner Music Group was the party holding copyright on a song that Lessig used in an unarguably fair-use manner. TechDirt is careful not to assume that an actual DMCA takedown notice was issued, on the likelihood that Google's automatic copyright-violation detectors did the deed. "The unintended consequences of asking tool providers [e.g., Google] to judge what is and what is not copyright infringement lead to tremendous problems with companies shooting first and asking questions later. They are silencing speech, on the threat that it might infringe on copyright. This is backwards. We live in a country that is supposed to cherish free speech, not stifle it in case it harms the business model of a company. We live in a country that is supposed to encourage the free expression of ideas — not lock it up and take it down because one company doesn't know how to adapt its business model. We should never be silencing videos because they might infringe on copyright."

Stony Stevenson writes "A light has been shone on one of the great mysteries of the internet. What is the point of the two forward slashes that sit directly in front of the 'www' in every internet website address? The answer, according to Tim Berners-Lee, who had an important role in the creation of the web, is that there isn't one. Berners-Lee revisited that design decision during a recent talk with Paul Mohr of the NY Times when Mohr asked if he would do any differently, given the chance. 'Look at all the paper and trees, he said, that could have been saved if people had not had to write or type out those slashes on paper over the years — not to mention the human labor and time spent typing those two keystrokes countless millions of times in browser address boxes.'"

Jos Poortvliet writes "After another 6 months of hard work by over 700 people, after fixing over 10,000 bugs and granting 2,000 wishes, KDE 4.3, or 'Caizen,' is here (the release takes its nickname from the Japanese philosophy of continuous improvement). The KDE Desktop Workspace introduces, besides the usual stability and speed improvements, new widgets, the ability to 'peek' in a folder with folderview, and activities tied to virtual desktops. The KDE Application Suites feature improvements in the utilities like a more formats supported in Ark and the return of the Linux Infrared Remote Control system. Instant messenger Kopete introduces an improved contact list and KOrganizer can sync with Google Calendar. Kmail supports inserting inline images into email and the Alarm notifier has gained export functionality, drag and drop, and has an improved configuration. The KDE Application Development platform has seen work on integrating the Social Desktop and the new system tray protocol from Freedesktop.org. You can watch a screencast of the Desktop Workspace here."

An anonymous reader writes "Larry Lessig, known (hopefully) to everyone around here as a defender of all things having to do with consumer rights and fair use rights when it comes to copyright, is now on the receiving end of a DMCA takedown notice from Warner Music, who apparently claimed that one of Lessig's famous presentations violated on their copyright. Lessig has said that he's absolutely planning on fighting this, and has asked someone to send Warner Music a copy of US copyright law that deals with 'fair use.'" Reader daemonburrito notes that the (rehosted) "video remains available at the time of this submission."

ptorrone writes "Make: television debuted online and on public television (broadcast / cable tv). The series encourages everyone to invent, reinvent, recycle, upcycle, and act up. Based on the popular Make magazine, each half-hour episode hopes to inspire viewers to think, create, and, well, make. Each episode can be viewed or downloaded DRM-free, in HD on makezine.tv — the show is also available on Vimeo, YouTube, blip.tv and iTunes."

TedCHoward writes "On the heels of the recent mention of HyperCard comes the launch of a brand new site called TileStack. Cnet's Webware blog writes, 'The idea behind it is to bring old HyperCard stacks back to life by putting them on the Web, meaning you can take some of those long lost creations from the late '80s and early '90s and make them working Web apps. You simply upload them to TileStack's servers and they'll be converted and hosted for just you or the entire world to use once again... Since the service runs without Flash... TileStack is perfect for the iPhone and other devices that run on the Web.' They also have a video showing the upload process."

destinyland writes "The EFF just announced victory over a serial abuser of DMCA copyright notices. To set an example, their settlement required Michael Crook to record a video apology to the entire internet for interfering with free speech. He's also required to withdraw every bogus DMCA notice, and refrain from future bogus notices, never contest the original image again, and take a remedial class on copyright law. He'd attempted to use flaws in the DMCA to censor an embarrassing picture of himself that he just didn't want appearing online — but instead the whole thing backfired."
