3D-моделирование выявило важные особенности диффузионного поведения наночастиц

Компьюлента - 46 минуты 24 секунды назад
Некоторые наноразработки полагаются на то, как частицы движутся и диффундируют при неидеальных или даже экстремальных условиях. Американский химик Ригоберто Эрнандес исследовал взаимосвязь между диффузией и свойствами наносистемы, использовав компьютерное моделирование трёхмерной динамики движения частиц.

Rdio app undergoes a facelift, Android 4.0 support included

ANDROID Community - 2 часа 13 минуты назад

Those of you who were Rdio users prior to purchasing a Samsung Galaxy Nexus were probably wondering when it would be updated to Android 4.0. It is now perfectly compatible, and even underwent a much welcomed UI transformation. Like other music streaming apps, Rdio offers an great collection of over 12 million songs that can be instantly streamed to any Android device.


Just like Spotify and Grooveshark, songs can be cached for offline playback. It’s hard to decide which one to subscribe to – as all offer access to so many songs. But more likely than not, you’ve already taken a liking to one prior to reading this. And there, you’ve made your playlists and populated your music library through your personal account.

So why would you jump services if all offer the same features? You wouldn’t. And that’s why survival and growth completely depends on future device compatibility. As long as Rdio, Spotify, Grooveshark, and many others continue to support the latest firmware and devices – they’ll be able to retain there subscribers.

Android Community Evening Wrap-Up: February 6, 2012

ANDROID Community - 3 часа 45 минуты назад

We had quite a few stories today, and the most interesting may well be the rumor of some Android-based HUD glasses from Google. There have been rumors suggesting a secret project is in the works to bring some augmented reality glasses to public testing soon. It will apparently only be for one eye, and on the side. Unfortunately, it’s not likely they will be see through – so don’t plan on becoming a ‘terminator’ quite yet.


Verizon’s Samsung Galaxy Nexus had an update to 4.0.4 leak today, and it has proved to improve users’ signals in just about every way. It hasn’t officially rolled out yet, but isn’t difficult at all to install. Find out more information on how to upgrade here.

Have you checked Facebook lately on your Android smartphone or tablet? The official Facebook app should see mobile ads incorporated starting in March, so enjoy your ad-free application while you can! Adding inline ads could potentially boost their revenue to unheard-of amounts. There’s no doubt you’ve accidentally tapped one of those ads while navigating through countless other applications.

And we were also graced with another Samsung Galaxy S III rumor – one that suggests it will be 7mm thin! So now we’ve got a 7mm, waterproof, 12MP camera, and full-touchscreen display that spans . At this point it’s hard to imagine an area of improvement for the device.

LibreOffice Android port progresses to prototype

ANDROID Community - 4 часа 43 минуты назад

A few months ago we brought you news that LibreOffice, the open source offshoot of popular free office suite Open Office, was headed to Android. While it would be wrong to say that the team of developers is making rapid progress, progress is nonetheless being made. The prototype app for Android tablets (Honeycomb and Ice Cream Sandwich) was recently shown off in a single screenshot. Without passing too much judgement this early in development, I can say this: for those frustrated with the relatively sparse feature-sets of mobile office suites like Google Docs, it’ll be well worth the wait.

LibreOffice is published by a series of volunteer developers called The Document Foundation. The team is mostly former members of the Open Office project who left when Oracle bought Sun Microsystems, who had previously funded Open Office. With more than 8 million downloads in 2011 alone, it’s fast become one of the favorite free office suites for desktops, and is included by default in many Linux distributions. In addition to Android and iOS versions, The Document Foundation hopes to create online editions of the various application in LibreOffice using HTML 5.

LibreOffice includes all the basics of an office suite: a Word-style document manager, spreadsheet program, presentation program (PowerPoint-style), database manager, vector tool and formula editor. It’s not clear which of these programs will make it to the Android port, though the first three would seem to be a given. There’s clearly a lot of work that needs to be done (especially to create a powerful yet touch-friendly interface) but the project remains an exciting one for work-focused Android users.

Cowon extends its PMP line with Z2 Plenue

ANDROID Community - 5 часа 13 минуты назад

Believe it or don’t, there’s still plenty of people out there who just want a little flexible media playing in their mobile device, and at least six or seven of them haven’t already bought an iPod Touch. For that market, Cowon makes some stylish and acoustically sound products, which they’ve lately been loading with Android. The latest is the Z2 Plenue, and no, we don’t know what “Plenue” means, either. The device is on sale in South Korea now, but probably won’t make it outside of Asia for a few months at the very least.

With a 1Ghz processor and 512MB of RAM, not to mention a 3.7-inch 800×480 OLED display, the Z2 Plenue is the equal of the original Nexus One and HTC Incredible, at least as far as power and visibility goes. Storage options range from 8GB all the way to 32GB, with the extra trick of being NTFS-formatted, so files larger than 4GB (like, say, HD video rips) can fit on the device’s storage without issue. If even that isn’t enough, you can augment it with the open MicroSD card slot. Connection options include the basic Wi-Fi and Bluetooth, and you get an FM tuner to sweeten the deal.

While three capacitive navigation buttons are shown, so is a pretty heavily modified Android skin, to the point that it’s impossible to tell which version of Android is running underneath it. Based on the promo photo there appears to be some kind of proprietary app store that’s definitely not the Android Market. If you’re interested and you’re in Korea, you can pick up a Cowon Z2 Plenue for $200-300 in local currency, depending on storage capacity.

HTC makes “Studio” design division under CEO

ANDROID Community - 6 часа 7 минуты назад

HTC doesn’t look so hot at the moment, at least from a financial point of view. But that doesn’t mean they’re resting on their laurels. The Taiwanese manufacturer announced a new department, code-named “Studio”, which will report directly to CEO Peter Chou. The Studio division (which probably isn’t its final name) will be compromised of leading designers and engineers, with the purpose of overcoming some of the company’s identified shortcomings in its 2011 devices.

Two design aspects in particular that they identified as needing revision are thinness of phones’ profiles and the relationship between LTE connections and battery drain. Anyone who’s owned an HTC ThunderBolt can identify with these problems, and its successors the Rezound and Vivid aren’t all that much better. All this is compounded by smaller and for the most part better phones from HTC’s primary competitors: the Samsung Galaxy S II LTE (AKA the Skyrocket on AT&T) and the Motorola DROID RAZR. HTC’s obviously working fast, as the much-leaked HTC Ville headed to Mobile World Congress is already shaping up to be a thin, powerful phone.

Also of note in their conference call was a hint towards a more “open-minded” attitude when it comes to selecting components. The HTC representative specifically mentioned CPUs in this context. Considering the Ville’s supposed launch partner, the HTC Edge, that makes a lot of sense: the Edge will probably be the first smartphone to use an Nvidia Tegra 3 processor, as opposed to HTC’s usual Qualcomm SoC’s. Both devices are expected to make an appearance at HTC’s pre-Mobile World Congress event in late February.

Samsung Galaxy Nexus in White official: Coming February 13

ANDROID Community - 6 часа 23 минуты назад

We knew it was coming but today Samsung made it official. The Samsung Galaxy Nexus in white is real, and coming soon. It will be available starting on February 13th and will be identical to the regular model — only white as snow. Sadly it being available so late it has missed the snow for many markets, but then that depends on where you live.

Like mentioned above, the white edition will be on sale starting February 13th in locations throughout the UK, and we can expect more to follow shortly. No US carriers have announced any plans yet but most likely we’ll see it hit some 3rd party retailers like Amazon, RadioShack and others eventually — only the GSM version.

We first saw some pre-orders followed by officially leaked pictures but today Samsung has officially confirmed the handset. Since these are GSM and unlocked Samsung will be offering them for a pretty penny, but you’ll be able to choose from the 16GB and the 32GB models. Samsung themselves didn’t offer any official pricing but being unlocked they probably wont be too cheap.

Do you want a white Galaxy Nexus?

Google clarifies CDMA debacle: still supporting developer phones, not publishing AOSP code

ANDROID Community - 7 часа 30 минуты назад

After a firestorm of controversy late last week, Google, Verizon and a lot of others caught flack for apparently abandoning support of the CDMA flavors of its developer devices: the Galaxy Nexus and Motorola XOOM on Verizon, as well as the older Nexus S 4G. After the devices disappeared from the listings on the Android.com developer portal. The only thing remaining for any CDMA device is the early builds for the Galaxy Nexus, and those are marked  as “for reference only”. This led to speculation that Google had halted support for said devices, and in a way, they have.

Google will no longer publish the updated system software images for the three devices, because connecting to a CDMA network requires digital files and programs signed by the operator of that network, which can’t be open-sourced. Technically, this means that the entire ROM can’t be called “open source”, and therefore doesn’t belong on AOSP (Android Open Source Project). However, Google has updated its initial statement on Google Groups, reassuring device owners that they will continue to support the software even though it isn’t being posted to the AOSP repository.

Here’s their second statement in full (emphasis added):

Hi, all! Thanks for all the questions. Here’s a quick omnibus to answer thequestions folks have asked… First, just to be clear this change is only related to AOSP support forthese devices — that is, personal custom builds. These are obviously still officially-supported Nexus devices for everyday use, they will receive official software updates, and so on. Similarly, these are still fully-supported development devices for app developers.

Second, as I noted at the top of the thread, Nexus devices will still haveunlocked bootloaders, and we’ll continue to make available as many of the closed-source binaries as we can. CDMA support in AOSP has always been morechallenging than GSM, and this change is a reflection of that reality.

On that topic, here’s a quick clarification on the core issue. Every devicehas a number of closed-source software packages included on it. Though Google distributes some of these binaries for Nexus devices for use with AOSP, Google does not own the software. Rather, this software is variously owned by the device manufacturer, the carrier, and their suppliers. We tryto get distribution rights for as many of these binaries as possible, butin some cases it is difficult or impossible to obtain these rights. (CDMA specifically has a tricky history of intellectual property.) Combined withthe technical issues of needing to sign the apks correctly, this has prevented us from obtaining the distribution rights we need to supportthese devices in AOSP.

Finally, we will of course continue to work on improving support. If we can resolve these issues, we’ll certainly restore CDMA support to AOSP. In the meantime, we’ve updated our docs to be more accurate about the degree ofsupport.

So what it boils down to is this: Google either had some sort of agreement with the owners of the copyrighted code in the CDMA portions of the Android software images, or the owners either didn’t know or didn’t care about its distribution. Apparently, that’s no longer the case. Google has lost the right to distribute this code, or never had it in the first place and it’s now being enforced. GSM and WiFi operate on a collection of open standards, so this isn’t a problem for other phones like the standard models of the Galaxy Nexus and Nexus S or the WiFi-only XOOM.

Google claims that they will continue to support CDMA phones to the best of their abilities, particularly when it comes to the binaries that developers need. They also hope to restore CDMA support to the Android Open Source Project at some point. This still leaves Android users with two questions: one, does this limited support include software updates directly from Google, or must the CDMA devices get them after the carriers and manufacturers have added their copyrighted code? If users can’t download the latest software from Google, how could they get it any other way?

And two: why the sudden change in policy? Why is this CDMA restriction in the open source code being enforced now, almost a year after the XOOM became the first developer device on a CDMA network? At this point, Google isn’t being particularly chatty on either subject.

Remember that Nexus and developer devices have always come with, and will continue to come with, unlockable bootloaders. The impact that this move has on custom ROMs for Nexus phones and the XOOM is almost zero. Even so, this change sets a worrying precedent for anyone who wants to use a developer device on the CDMA network of their choice.
