It missed being a recursive acronym by a single letter...
TCP is known for being the go-to protocol for stable connections over the internet. There are some things you can guarantee: you will not lose bits of data, packets will arrive in order, incorrect packets will be checked and redelivered, and both endpoints will be roughly metered to the least capacity. It is easy to develop applications around the TCP protocol, it does the hard problems for you.
UDP, on the other hand, frees its packets in a fountain to hopefully land where it is intended. This protocol is fast, but a pain for applications that need some level of reliability. Quick UDP Internet Connections (QUIC), from Google, leverages UDP to create multiple independent, even encrypted connections. While TCP could be made faster, it is beyond the jurisdiction of web browsers; support is embedded into the operating system itself. This leaves building upon UDP, suffering with TCP, or not being compatible with about every network hardware installed just about anywhere.
This comes on the heels of SPDY, Google's other open protocol. SPDY is built around HTTP and both presume a reliable protocol underneath, where TCP is the usual candidate. A large advantage of SPDY allows assets to simultaneously stream over a single connection. TCP will, unfortunately, freeze the entire connection (and thus each stream) when a single stream drops a packet. QUIC, based upon UDP, can then be used to accelerate SPDY further by allowing truly independent multiplexing.
QUIC will be used for "a small percentage of Chrome dev and canary channel traffic to some Google server", for experimentation purposes. The code itself is licensed under BSD and, as such, could migrate to other browsers in due time.

Later this week, Google is updating its Glass, well, glasses to add new features. Among the new features, Google is including a full web browser and a couple of new voice controls.
The full web browser will output to the Glass display and can be accessed by hitting the appropriate button. Users will be able to access the web using the Wi-Fi chip, and it will be controlled by the touchpad and motion controls. For example, users can scroll pages by moving a single finger forward on the touchpad. Zooming is handled by using a two finger guesture on the touchpad. Finally, while zoomed in, users can move their head around to pan around the page.
The motion control bit is actually an intuitive idea, though I expect bystanders will find those browsing the web on their Glass a bit odd as they hold two fingers to their glasses and move their head about. (Hopefully people do not try browsing reddit while walking, however.)
The upcoming Google Glass update also adds a few more voice controls to the mix. Using voice commands beginning with "ok glass," users will be able to reply to text messages, answer calls, and send photos to other people on their contact list.
Finally, Google has lifted the contact list restriction from a list of ten friends. Users can now access their entire Gmail contact list.
I'm glad that Google is continuing to improve the Glass software. According to The Verge, this new update will be rolled out over the next few days to the Explorer Edition units currently in the hands of developers. I'm looking forward to the final consumer release.

One of the neat features of the chat application built into the Gmail web interface is the ability to receive and place phone calls to and from your Google Voice number. And unlike the Google Voice interface, calls placed using the Gmail Talk chat widget are completely free.
Unfortunately, the new Hangouts replacement (currently not mandatory) brought over from Google + does not support the calling features of Google Talk. As such, users wanting to call phones and not just video chat with other Google + users will need to stick with the old Google Talk chat or use Google Voice and pay for outbound calls.
The good news is that the phone call features will be rolled into the new Hangouts feature eventually. According to Google employee Nikhyl Singhal, “outbound/inbound calls will soon be available.” He also indicated that future versions of Hangouts will further integrate the feature set of Google Voice (which likely refers to SMS). Unless you particularly want video chatting, I would recommend sticking with Google Talk until the new version of Hangouts is more fleshed out.

Google has begun a worldwide rollout of its re-designed Google Play store for Android smartphones and tablets. Over the next few weeks, users will be presented with a new, and simplified, user interface for the Play store.
Mobile devices running Android 2.2 (Froyo) and above will recieve the update. The redesign has moved to a simpler layout that groups similar content together and uses larger images to draw in the user's attention. A continuous scroll feature will introduce recommendations for related content as you scroll down.
Google has also reportedly simplified the checkout process, in order to reduce the time between buying an app, purchasing an MP3, or renting a movie and actually being able to begin consuming the content.
From Google's blog post and what little screenshots they have shown off of the new layout, I think Google has made some positive changes here, but I'll reserve final judgement once I've been able to test it out for myself.
Has your Android device received the Play store update yet?

Tagged: pavilion 14, hp, google, Chromebook
HP recently launched the Pavilion 14 Chromebok, which is a notebook running Google’s Chrome OS operating system and suite of web applications. The Pavilion 14 Chromebook is a 14” laptop measuring 0.83-inches thick and weighing 3.96 pounds.
The new Chromebook is based on one of HP’s existing Windows laptops–the Sleekbook 14-b010us. It features a 14” screen with a resolution of 1366x768, full qwerty keyboard and track pad, and a webcam.
External IO includes:
- 3 x USB 2.0
- 1 x HDMI
- 1 x Ethernet (10/100)
- 1 x Card reader
- 1 x Headphone jack
The system is powered by a dual core Intel Celeron 847 clocked at 1.1 GHz, 2GB of RAM, and a 16GB solid state drive (SSD). Dual-band 802.11 b/g/n Wi-Fi and Bluetooth 3.0 radios are included, but unlike other Chromebooks there is no cellular connectivity out of the box. Further, Google is providing 100GB of Google Drive cloud storage for free (for two years). HP estimates system battery life at 4.25 hours.
The Pavilion 14 Chromebook is available now on HP’s website for $329.99. That makes it one of the most expensive Chromebooks on the market. Chrome OS has come a long way, and even includes a minimal desktop. The hardware looks nice, but I would have liked to see a higher resolution display along with cellular modem for the price, however. It will be interesting to see how well the larger 14" form factor sells.

Reviews of Google’s latest Nexus 10 tablet are starting to pop up around the web, and the results are a bit mixed -- mostly positive with the price being its saving grace. The display and inclusion of Android 4.2 is nice, but will it dethrone the iPad? It's time to find out!
As a refresher, the Nexus 10 is 10” tablet powered by a dual core ARM Cortex-A15 system on a chip. On the outside, it has a 10.055” touchscreen display with a resolution of 2560 x 1600 (300 ppi, 16:10), 5MP rear camera, and a 1.9MP webcam on the front of the tablet.
External IO includes micro USB, micro HDMI, and a 3.5mm headphone jack.
Internally, the Nexus 10 features a dual core Samsung Exynos 5250 SoC clocked at 1.7GHz, a Mali T604 GPU, 2GB of RAM, and either 16GB or 32GB of storage. A 9,000 mAh battery is also preset. Bluetooth 4.0, 802.11 b/g/n Wi-Fi, and NFC radios are also included. The new tablet is also running an updated version of Jelly Bean Google has dubbed Android 4.2.
The 16GB model is listed at $399 while the 32GB Nexus 10 is $499. Both models will be available on November 13th.

While many PC and component manufacturers are having a rough time in 2012, ASUS is not one. Thanks to their wholehearted adoption of Android devices like the Nexus 7 they have seen their income from mobile devices jump from 7% of their revenue to 16%. That total revenue also had significant growth, their profits are 43% higher than this quarter a year ago. That growth rate is very impressive in the current economy and seems to refute many analyst's predictions that we are moving into a post PC market. ASUS also has to thank their Transformer series as the paired tablet and keyboard device is proving quite popular and will be one of the main competitors to Microsoft's new Surface devices. ASUS told The Register they plan to become the second largest seller of tablets and the largest retailer of touch devices.
"Asus to you and me - has pulled a surprise jump in profit out of the bag as its tablets make up for slow PC sales.
The Taiwanese firm reported its largest quarterly profit in more than four years, spurred by its partnership with Google on the Nexus 7 and the enduring popularity of its own-brand snap-on keyboard fondletops."

While Android gets most of the attention, it is not the only operating system from Google. Chrome OS was released two years ago, and despite the rising popularity of smartphones and tablets, it is still very much alive and kicking on the cloud-connected “Chromebooks.”
In fact, earlier this week Samsung announced a brand new Chromebook powered by its own Exynos 5250 ARM System of a Chip (SoC). The new system is lighter than the company’s previous Chromebook offerings at 2.43 pounds and is less than an inch thick. The specifications are not impressive for a laptop, but in the context of a Chromebook where much of the processing is done on Internet-connected servers the internals should ensure that you get good battery life – up to 6.3 hours – out of the mobile machine.
The 11.6” Chromebook has a display with a resolution of 1366 x 768 pixels, 1.5W stereo speakers, and a full physical keyboard with trackpad.
External I/O options include:
- 1 x USB 3.0
- 1 x USB 2.0
- 1 x Headphone/Mic combo jack
- 1 x SD card slot
The USB 3.0 option is interesting, and should allow you to hook up fast external storage should you need more caching space for offline use.
On the outside, the Chromebook very much resembles a standard laptop, but on the inside it is closer to the specifications of a smartphone or tablet. Interestingly, Samsung has chosen its Exynos 5250 system on a chip to power the XE303C12 Chromebook. That processor is packing two Cortex A15-based ARM CPU cores and an ARM Mali T604 GPU. While the Exynos 15 is capable of clocking up to 2GHz, it is unclear whether or not the Chromebook will feature chips clocked at that speed or not. It is certainly a possibility though, since the laptop form factor would provide ample cooling versus a more constrained smartphone or tablet. Beyond the SoC, Samsung has packed in 2GB of RAM and a 16GB solid state drive (SSD). Additionally, the XE303C12 Chromebook includes a Trusted Platform Module (TPM) chip – useful for business uses – and 802.11 a/b/g/n Wi-Fi radio with a 2x2 antenna configuration.
The new Samsung Chromebook is available for pre-order now, and will be officially available for purchase at Best Buy, Amazon, Newegg, and other retailers beginning October 22, 2012. It has an MSRP of $249.99.
I’m interested to see how this compared to the Windows RT offerings, and whether the cheaper price will win people over versus those devices. On the other hand, it may be that Android tablets – like the Nexus 7, Nook Tablet, and new Kindle Fire tablets – are the favored devices for all but road warriors needing a decent keyboard. What do you think?

Two companies which for the most part sold software only are making a name for themselves in the hardware sector, in two very different ways. Google's Android has become quite a player and the upcoming release of the Nexus 7 platform is anticipated by many mobile players because Google has no intentions of making its own phones. Instead they will make their money licensing the platform to a variety of established cellphone and tablet manufacturers, as they have in the past. According to what DigiTimes has heard, Microsoft is going in the exact opposite direction with Surface and will be continuing with the same plan as their tablet, which has already caused negative backlash from many of the major player in the market such as Acer. Designers of Microsoft Win8 based phones are required to use the same platform and interface in order to meet the requirements of Microsoft's licensing agreement which will make phones difficult to differentiate as competitors are very limited in the customization they can offer, at least on the software side. To make the market even more confusing, Microsoft is reaching out to Pegatron to manufacture their own branded Surface phone, which will find its self in direct competition with the phones from established players, the ones Microsoft is count on to license the portable version of Win8. It would be hard to come up with another way that Microsoft could make licensing their new OS even less attractive for OEMs and ODMs.
"Google and Microsoft both reportedly plan to extend the Nexus 7 and Surface tablet lineups to include smartphones as a means to further increase the penetration of their own platforms, but the two companies will implement the strategies in a different tune, according to industry sources.
Google aims to launch smartphones based on its Nexus 7 platform in cooperation with a number of smartphone branded vendors with Samsung Electronics, LG Electronics, Sony Mobile Communications and HTC likely to be potential partners, said the sources.
On the other hand, Microsoft is reportedly tapping ODM maker Pegatron for the production of WP8-based smartphones slated for launch in the first half of 2013, the sources indicated."
