Keith and I are pleased to announce the immediate availability of TeleBT, a new Altus Metrum ground station product providing the equivalent of TeleDongle plus Bluetooth. TeleBT working with AltosDroid on an Android device provides everything needed to monitor a rocket in flight, record telemetry, and know how to walk right to the airframe after it's back on the ground. The Bluetooth capability of TeleBT is also supported by AltosUI on Linux, and with a micro USB cable TeleBT works just like TeleDongle on Windows, Mac, and Linux systems running AltOS version 1.2.1 or later.

Savor this spring session of CTIA 2013, because it will be the last. In Las Vegas' Venetian Ballroom, moguls of the wireless world took the stage for the show's opening keynote to discuss the expansion of wireless service in North America, the future of the CTIA shows, and women in wireless.After the show closes on Thursday, the Wireless Association will merge the spring and fall CTIA shows will merge to form one session. 2014's show will be a so-called "super show."CTIA as holiday launchpadLike this year's show, the next CTIA session will also be in Las Vegas. Taking place from September 9-11, the time has been chosen to give manufacturers the chance to launch products into the holiday season.This should help CTIA compete with the other Vegas tech show, CES, which occurs in January, after the holiday feeding frenzy.A subdued send offThe last opening keynote of the CTIA spring show began on an appropriately dour note. CTIA President and CEO Steve Largent began his address with condolences to the victims of Oklahoma's deadly tornadoes.Former NFL player Largent is an Oklahoma native himself, and served his state in the U.S. House of Representatives before shifting to a career in the wireless industry. He praised the work of emergency workers in his home state, and urged the audience to text a donation to the Red Cross.Women in WirelessLargent then introduced newly appointed FCC Commissioner Mignon Clyburn. The first woman to hold this position, Clyburn was still in her first week as commissioner when she took the stage on Tuesday.Clyburn was followed by Mary Dilon, president of U.S. Cellular and CTIA Chairwoman. She stressed the need to encourage young women to enter the wireless industry, joking that the CTIA rest rooms are the "only place where the men are waiting and the women just waltz right in."Despite an overall gender imbalance in the industry, the CTIA opening keynote was able to muster an impressive all-female panel of wireless moguls. Executives from Qualcomm, Target and more joined Dilon for a discussion of their own career paths, and their vision for the industries future.

Using Solr With TYPO3 On Debian Wheezy TYPO3's default search extension called "Indexed Search" is fine for small web sites, but if your web site is bigger (> 500 pages), it is getting very slow. Fortunately, you can replace it with a search extension that uses the ultra-fast Apache Solr search server. This tutorial explains how to use Apache Solr with TYPO3 on Debian Wheezy.

It's been all over the internet, so you probably heard it already: Google Hangouts no longer receives messages from XMPP users. Before, you could easily chat with "federated" users from other Jabber servers. While of course the various open-source people are not amused -- for me, most of my contacts disappeared, so I then uninstalled Hangouts to get back Google Talk (apparently this works if Talk was preinstalled in your phones firmware) -- this bears some larger risks for Google: Reputation: Google used to have the reputation of being open. XMPP support was open, the current "Hangups" protocol is not. This continuing trend of abandoning open standards and moving to "walled garden" solutions will likely harm the companies reputation in the open source community Legal risk of an antitrust action: Before, other competitors could interface with Google using an indepentend and widely accepted standard. An example is United Internet in Germany, which operates for example the Web.de and GMX platforms, mail.com, the 1&1 internet provider. By effectively locking out its competitors - without an obvious technical reason, as XMPP was working fine just before, and apparently continues to be used at Google for example in AppEngine - bears a high risk of running into an antitrust action in Europe. If I were 1&1, I would try to get my lawyers started... or if I were Microsoft, who apparently just wanted to add XMPP messaging to Hotmail? Users: Google+ is not that big yet. Especially in Germany. Since 90% of my contacts were XMPP contacts, where am I likely going to move to: Hangouts or another XMPP server? Or back to Skype? I still use Skype for more Voice calls than Google (which I used like twice), because there are some people that prefer Skype. One of these calls probably was not using the Google plugin, but an open source phone. Because with XMPP and Jingle, my regular chat client would interoperate. An in fact, the reason I started using Google Talk the first place was because it would interoperate with other networks, too, and I assumed they would be good at operating a Jabber server. In my opinion, Google needs to quickly restore a functioning XMPP bridge. It is okay if they offer add-on functionality only for Hangout users (XMPP was always designed to allow for add-on functionality); it is also okay if they propose an entirely new open protocol to migrate to on the long run, if they can show good reasons such as scalability issues. But the way they approached the Hangup rollout looks like a big #fail to me. Oh, and there are other issues, too. For example Linus Torvalds complains about the fonts being screwed up (not hinted properly) in the new Google+, others complain about broken presence indicators (but then you might as well just send an email, if you can't tell whether the recepient will be able to receive and answer right away), but using Hangouts will apparently also (for now -- rumor has it that Voice will also be replaced by Hangups entirely) lose you Google Voice support. The only thing that seems to give positive press are the easter eggs... All in all, I'm not surprised to see over 20% of users giving the lowest rating in the Google Play Store, and less than 45% giving the highest rating - for a Google product, this must be really low.

If you're running an Android device with GNU userland Linux in a chroot and need a network over USB cable, here's a quick primer on how it's setup.When doing Openmoko hacking, one always first plugged in the USB cable and forwarded network, or like I did later forwarded network over Bluetooth. It was mostly because the WiFi was quite unstable with many of the kernels.I recently found out myself using a chroot on a Nexus 4 without working WiFi, so instead of my usual WiFi usage I needed network over USB... trivial, of course, except that there's Android on the way and I'm a Android newbie. Thanks to ZDmitry on Freenode, I got the bits for the Android part so I got it working.On device, have eg. data/usb.sh with the following contents.#!/system/xbin/shCHROOT="/data/chroot"ip addr add 192.168.137.2/30 dev usb0ip link set usb0 upip route delete defaultip route add default via 192.168.137.1;setprop net.dns1 8.8.8.8echo 'nameserver 8.8.8.8' >> $CHROOT/run/resolvconf/resolv.confOn the host, execute the following:adb shell setprop sys.usb.config rndis,adbadb shell data/usb.shsudo ifconfig usb0 192.168.137.1sudo iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.137.0/24echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward sudo iptables -P FORWARD ACCEPTThis works at least with Ubuntu saucy chroot. The main difference in some other distro might be whether the resolv.conf has moved to /run or not. You should be now all set up to browse / apt-get stuff from the device again.

Silence is golden, but music has become a necessity in the past few years as office workers get asked to do more and more work in ever noisier environments - it's no wonder sales of headphones have rocketed in recent years.They're just as useful in noisy city streets and the aircraft cabin, where the dodgy headphones handed out to passengers in economy class can leave you straining to hear the dialogue in a film. Some are so uncomfortable that your ears can be burning by the time you touch down at your destination. Noise cancelling is handy if you're flying or working in very loud offices, but forget Bluetooth at 40,000ft - and, actually forget Bluetooth completely; it's more of a pain to pair with a smartphone than untangling a pair of in-ears, and the headsets need regular charging, too, which makes them high maintenance. Wait for NFC connectivity. For work, you'll need a comfy pair that doesn't spill noise sideways to colleagues, while for those in a home office - or listening to old LPs in the loft - that's not so important. We've selected some old classics, newer styles and our favourites from throughout the genres, but they all have something in common: they all cost north of £150/$180, and for good reason.Pioneer HDJ-1500-S - £150/US$180/AU$250Made for the DJ booth, these flexible cans are hard-working and high volume These headphones are all about loudness in noisy environments. A model designed primarily for DJs, they're very well made, with easily turnable hinges (which ought to help avoid accidental breakages) above the rather narrow leather ear-cups that spin 90 degrees without any friction. Sporting a high-end yet sleek design and feel, these mid-range 305g (10.75oz) cans have a comfy foam and leather-backed headband and ship with a detachable coiled cable with a 3.5mm gold-plated connector that easily stretches out to around 3m. Worn around the neck, these cups move easily, though they can feel a little restrictive despite their narrow design, which slips into a 27 x 23cm (10.6 x 9.1-inch) fake leather drawstring bag. A 6.35mm jack plug adaptor is also supplied. Sound quality is best described as full - and loud; we're talking booming bass levels and plenty of dynamism. Probably the best aspect of these is that they are extremely efficient at blocking out ambient noise despite not having any active noise cancelling trickery. However, a major factor in that success is that the leather-lined cups fasten onto the head just a little too tightly for comfort. Wear them for 20 minutes and they're thoroughly impressive, though much longer than that and they become quite uncomfortable. Available in silver or black, a little sound spillage makes these best used at home (the coiled cable is a little unwieldy for work) - or, of course, in the DJ booth.Klipsch Image X7i - £150/US$200 (around AU$230)Tiny teardrops with an anti-tangle cableEarphones with a three-button remote and a 'Made for iPhone' badge are ten-a-penny, but we've not come across a pair as tiny as the Klipsch X7i. Working best with the iPhone 3GS and above, the teardrop-style inserts are so small we feared they'd never emerge post-test, but they did after a throughly comfortable and darned impressive few outings. Sound quality is best described as warm, lively and full, with pin-sharp detail and stereo separation atop a mix that's got plenty of well-judged bass tones. Tunes go to high volumes without distorting, too, while blocking out more than enough ambient sound to rightly prove their 'noise isolating' claim; be careful when crossing roads. Being so small, they do occasionally slip and need repositioning, but rarely. They sell with a small elliptical zipped pouch made from neoprene (diving suit material), and surprisingly well-made it is, too. This contains a two-prong airline seat adaptor, shirt clip and four contrasting sizes and styles of silicon in-ear tips. Our only complaint is that you have to pretty much rip off and destroy the sturdy box it sells

We may be just hours from the launch of the new Xbox, but you didn't honestly expect the rumours to slow, did you? The latest is that Microsoft's previously-teased Illumiroom concept will be shown off alongside the new console later today.Windows bloggy guy and man-in-the-know Paul Thurrott said in a tweet that Microsoft's new immersive gaming experience will be appearing at today's event after all.Microsoft Research's Hrvoje Benko and Brett Jones stated in a previous interview with Engadget that IllumiRoom wouldn't appear until July, and as we'd heard nothing since, we'd accepted that Microsoft just wasn't ready to roll it out at its May 21 event. Looks like we might have given up hope too soon.Illumination stationThe other news Thurrott had to share was that the subsidised Xbox model mooted at one point has now been scrapped entirely.We previously heard that the new console will launch in two models - a $500 (around AU$510, £330) all-out version and a $300 (around AU$305, £200) model that would require a two year commitment to Xbox Live Gold membership.Why should we trust Thurrott? Well he was on the money about the reveal date for the new Microsoft console so we do have to give him some credit. But of course, we'd still recommend a scoop from the salt jar to be safe.
