Το Samsung Galaxy S 3 εμφανιζεται σε benchmark




Όπως μπορείτε να δείτε από τις εικόνες που μόλις δημοσιεύτηκαν, υπάρχει πράγματι μια απο τις συσκευές που απαριθμούνται τώρα στο AnTuTu ως "Samsung Galaxy SIII." Έχει ξεπέρασε όλες τις άλλες συσκευές που έχουν αξιολογηθεί, λαμβάνοντας το χρυσό κύπελο στην απόδοση. Για να δούμε όμως τα specs τις συσκευείς.Έχουμε ένα dual-core επεξεργαστή Exynos 4212 χρονισμένο στα 1.4GHz, 1GB RAM, μια 4,7 "οθόνη HD (1280 × 720), 2MP κάμερα μπροστά, 12MP κάμερα πίσω, και  Android 4.0

Ένα πράγμα που πρέπει να σημειώσουμε εδώ είναι το δίκτυο το οποίο αναφέρεται ως "GSM / WCDMA." Αυτό δεν σημαίνει απαραίτητα ότι δεν θα δούμε εκδόσεις CDMA ή LTE της συσκευής, αλλά απλώς ότι η συσκευή ήταν συγκρίσιμη μόνο GSM. Όλοι μπορούμε να ελπίζουμε είναι ότι αυτό το Exynos chipset λειτουργεί ωραία με LTE.

Samsung Galaxy S III benchmark !


Whoa there AnTuTu benchmark! Are you trying to out the most anticipated Android device of the year? It appears as if you are, and we thank you for that.
As you can see from the screenshots we just posted, there is indeed a device listed now in AnTuTu as the “Samsung Galaxy SIII.” It has topped all other devices that have been benchmarked, taking home the gold trophy for performance. If we cruise in the device listing for it, we seem to have a confirmation on specs for the phone. We have a dual-core Exynos 4212 processor clocked at 1.4GHz, 1GB of RAM, a 4.7″ HD display (1280×720), 2MP front camera, 12MP rear camera, and Android 4.0. Yeah, that sounds about right.

One thing to note here is the network which is listed as “GSM/WCDMA.” This doesn’t necessarily mean that we won’t see CDMA or LTE versions of the device, but just that the benchmarked device was only GSM. All we can hope is that this Exynos chipset is playing nicely with LTE or it may be a while before we see it here in the States.
With a teaser for the device already live and a date for unveiling set, we won’t have to post these wishy-washy benchmark results much longer.
Oh, and we should probably mention the benchmark disclaimer, as to not offend the Android voices of reason out there.

Google raises Gmail to 10GB free, 10-fold increase since launching in 2004

Google raises Gmail to 10GB free, 10-fold increase since launching in 2004
Eight years ago one gigabyte of online storage was a remarkable thing. One gigabyte of email? Preposterous, but that's exactly what Google offered back in 2004 with the launch of Gmail, and now that factor is increasing. Current Gmail users were floating at around 7.5GB of storage but, as part of all the Google Drive hoopla, that storage is now officially up to 10GB. That's a lot of spam and, for those of us who are already paying extra for more storage, it's even more room to grow before we upgrade to the next tier.

Google Drive : 5GB of free storage, goes official

http://www.droiddog.com/wp-content/uploads/2012/04/googledrive.jpg
After years of leaks, murmurs, and other familiar synonyms, Google's mythical cloud storage platform is now official... sort of. As Lady Fate would have it, the company apparently outed a memo of the features on its French blog earlier today, but before it could yank the 'pull' switch, an eagle-eyed reader managed to grab the text and run it through Google Translate. What's left is an official-as-you'll-get-right-now transcript of Google Drive's features, but contrary to the hype, it all feels way more enterprise-centric than consumers may have wanted. For starters, there's no real mention of music (we guess Google Music is on its own, there), and there's just 5GB of free storage for "documents, videos, photos, Google Docs, PDFs, etc." According to the brief, it's designed to let users "live, work and play in the cloud," with direct integration with Docs and Google+.


We're also told that Drive can be installed on one's Mac, PC or Android phone / tablet, while an iOS version will be "available in the coming weeks." Of note, Google's making this accessible to visually impaired consumers with the use of a screen reader. As for features? Naturally, Google's flexing its search muscles in as many ways as possible; if you scan in a newspaper clipping, a simple Search All within Drive will allow results to appear directly from said clipping. If you upload a shot of the Eiffel Tower, it'll show up whenever you search for the aforesaid icon. Moreover, Drive will allow folks to open over 30 types of documents directly from a web browser, including HD video, Adobe Illustrator, Adobe Photoshop and more -- "even without the software installed on your computer." For those concerned about access, the new platform will have the same infrastructure as any other Google Apps services, giving admins a familiar set of management tools on that end.
On the topic of storage, just 5GB are provided gratis, and while upgrade details are a bit murky on the consumer side, we're told that administrators can pony up $4 per month for 20GB of storage, with a maximum of 16TB per user; thankfully, Google Docs will not be included in your usage total. Finally, the note played up the ability to "attach documents directly into your Drive Gmail," and given that it's intended to be an open platform, Goog's promising to work with third party developers in order to enhance Drive's functionality even further. The source link below is still dead as of right now, but it simply can't be long before the lights are officially turned on. Oh, and if you're not enamored right now, the outfit's suggesting that "many more developments" will be arriving in the coming weeks.

Oracle and Google continue sparring over APIs

 

As the second week of the Oracle-Google trial got underway Monday, Judge William Alsup continued to probe the depths of Java and Android APIs and copyright law. Prior to the jury entering the courtroom, Alsup asked the Google team whether Google admitted that it copied the 37 APIs at the center of the lawsuit.
"I quibble with the word "copy," Google lawyer Bruce Baber said. "APIs have been out for long time, in books, on the web and available in (Apache) Harmony. We absolutely used and included them in Android so we would have them exactly right for the [Java] specification."
The APIs are essential to fully implement the Java language.
Judge Alsup asked what was special about the 37 APIs, which are a subset of the Java APIs, and what are core APIs. "The 37 are the ones where they [Oracle] think they can assert rights," Baber said. "Four of the 37 packages [java.lang, java.util, java.io, java.net] are core, and some of the other 33 are sub-packages."

"These are the packages programmers expect to have in Java language to write programs," Baber said. Android includes 51 API packages, some of which were developed by Google. Android's implementation of the 37 APIs call 28 packages that are not part of Java 2 SE, Google stated in its April 22 Copyright Liability Trial Brief. Judge Alsup told the two tables of seven lawyers each, representing Google and Oracle, that he wasn't convinced that the 37 APIs are the "Holy Grail" of copyright law. "I am curious why you would want the judge to instruct the jury that the 37 APIs are a whole. That is not what the evidence is," he said.
He cited U.S. code, USC 107, regarding fair use, considering the amount and substantiality of the portion used in relation to the copyrighted work as a whole.  "I turning over in my mind how we deal with the work as a whole issue," he said. Judge Alsup said he would tell the jury that copyright could extend to structure, sequence and organization of the APIs, and let the jury consider Google's fair use claim in its deliberations.

 Oracle's lawyer, Michael Jacobs, described the APIs as a body of work, and Google's use of Java APIs as akin to taking articles from a journal or notes of a song, citing case law.

Oracle's expert witness, John Mitchell, a professor of computer science at Stanford University, gave the jury a detailed tutorial in APIs and object-oriented programming. Following the tutorial, Jacobs attempted to establish through Mitchell's testimony that 37 APIs in question are unique, creative works that Google illegally copied from Java. "By and large, they are identical," he said, referring to the 37 Java APIs in Android.  Quantitatively, they are approximately 90 percent the same, he added. Google doesn't dispute that fact that it used the 37 Java APIs.
Mitchell also noted code beyond the APIs, from the Java code base, that he found in Android code, disputing Google's claim that it applied it developed Android in a "clean room" environment.
The specific example of copied code was "range check," 9 lines of code that were almost identical in Java and Android.  Mitchell also asserted that some Android source code was generated through decompiling Java class files. "The developers had access to and used an Oracle (Java) installation," he said.

http://blog.jaxlondon.com/wp-content/uploads/2011/09/71012c5ba59e73243b7fdc6df54d8668.jpg

In his cross-examination of Mitchell, Google lead lawyer Robert Van Nest tried to establish that the Java programming language is free for anyone to use without a royalty, as Oracle CEO Larry Ellison stated in his deposition in the case, and that the core APIs, such as java.net and java.io, are integral to the language specification.
Van Nest went down the APIs as parts of speech path, a description of how to perform a task rather than the specific implementation. He cited Mitchell's video deposition in which he described packages, names, classes, interfaces, methods, named relations between methods and other elements as "parts of speech" that make up APIs.
Van Nest also addressed the code analysis Mitchell citied in his testimony during direct examination, in which 12 files with code in common between Android and Java were identified. In one of the files, Timsort.java, only nine lines in a "range check" function were found, Van Nest noted. "It's still nine lines," Mitchell said.
Van Nest asked him if it were true only that only the nine lines of "range check" from the 12 files were found on a handset. Mitchell agreed.
In redirect, Jacobs asked Mitchell about the significance of "range check."  He said he found "range check" was called 2,600 times in his study when a handset is started up.
According to a Google spokesman, the "range check" code is not in the latest Android version shipped by the company.

Samsung could announce sCloud service on May 3



According to Korean tech site MK, Samsung might be prepping up its very own cloud service. It's going to be called, and we are not joking, S-Cloud. In its core, it's going to be similar to Apple's iCloud, but will offer much more, according to the report.
For starters, there won't be any limitations on the things you could upload, which means it will work like Dropbox and the upcoming Google Drive. It'll even come with access to movies, popular TV shows and music. Free and paid content will also be available to various Samsung products such as laptops and tablets.


Furthermore, the amount of storage S-Cloud would offer is said to be more than 5GB, with Microsoft handling the server-side of the operations. We'll find if any of this is true on May 3, when Samsung will unveil its latest flagship Android smartphone.

Ο εφευρέτης του Internet κατηγορεί τις Google και Facebook για τα δεδομένα που συλλέγουν


Σε πρόσφατη συνέντευξη του στην ιστοσελίδα ‘The Guardian’, ο εφευρέτης του Παγκοσμίου Ιστού, Tim Berners Lee, κατηγορεί ευθέως τις Google και Facebook ως προς τα δεδομένα των χρηστών που συλλέγουν.

Χαρακτηρίζοντας τες ως “ιντερνετικά σιλό”, αναφέρει ότι οι δύο αυτές εταιρείες έχουν κατορθώσει να παγιδεύσουν στα δίχτυα τους ολόκληρο το Διαδίκτυο. Αυτό που κάνουν είναι να συλλέγουν όσο το δυνατόν περισσότερες πληροφορίες για τους χρήστες των κοινωνικών δικτύων τους και στη συνέχεια να αρνούνται να τις επιστρέψουν άμεσα μόλις αυτοί το ζητήσουν.

“Ένα από τα θέματα των κοινωνικών δικτύων είναι ότι οι εταιρείες τους έχουν στην κατοχή τους όλα αυτά τα δεδομένα, ενώ εμείς όχι… Δεν υπάρχει κανένα πρόγραμμα που να μας παρέχει πρόσβαση σε όλα τα δεδομένα που διατηρούν.
Σε οποιαδήποτε ιστοσελίδα και αν ανεβάζετε τα δεδομένα σας, θα πρέπει να είστε σίγουροι ότι αργότερα θα μπορούν να σας επιστραφούν. Στη θέση σας θα ζητούσα κάτι τέτοιο πολύ τακτικά, με την ίδια συχνότητα που κάνω back up στον υπολογιστή μου. Ίσως το αν τα εγγόνια μας θα μπορούν ή όχι να βλέπουν τις φωτογραφίες μας να βασίζεται στην επιλογή των ιστοσελίδων αυτών.”

Planetary Resources, μυστηριώδης διαστημική εταιρεία από τους επικεφαλής της Google και τον James Cameron


Όπως αποκαλύπτει δημοσίευμα του περιοδικού Technology Review του MIT, την επόμενη Τρίτη 24 Απριλίου θα κάνει το ντεμπούτο της μια νέα μυστηριώδης εταιρεία με την ονομασία Planetary Resources.

Η εταιρεία θα ασχολείται με την εξερεύνηση του διαστήματος -και συγκεκριμένα την εξόρυξη αστεροειδών- με σκοπό την εξεύρεση νέων πόρων για επέκταση των ήδη υπαρχόντων. Πίσω από τη χρηματοδότηση της βρίσκονται μεγάλα ονόματα όπως αυτά των Larry Page και Eric Shmidt της Google αλλά και αυτό του διάσημου σκηνοθέτη James Cameron.

Επικεφαλής του project θα είναι o ελληνοαμερικάνος Peter H. Diamandis, ο πρώην επικεφαλής αποστολών της NASA, Chris Lewicki και ο βετεράνος αστροναύτης Tom Jones. Η εταιρεία υπόσχεται να “επαναπροσδιορίσει την έννοια των φυσικών πόρων” και να αυξήσει το Παγκόσμιο Ακαθάριστο Προϊόν (GDP) κατά αρκετά τρισεκατομμύρια δολάρια.
Περισσότερες λεπτομέρειες θα γνωρίζουμε την ερχόμενη Τρίτη από την παρουσίαση του project που θα πραγματοποιηθεί στο “Museum of Flight” στο Σιάτλ.

Google TV's TV and Movies app gets to know you better with ratings, favorites and more

Image
At the center of the revamped Google TV experience that rolled out last fall is its TV & Movies app, which is a blended guide of content currently airing live on TV and available for streaming from the popular internet services (Netflix, Amazon, HBO Go). As Product Manager Rishi Chandra mentioned when we caught up with him at CES, personalization is something Google will be focusing on going forward and that's shown in the updated app being pushed out today. When it's first opened, users will login and be asked to rate a few movies and shows so it can get a sense of their tastes to know what to present, Netflix-style.
There's more information displayed up front too, with expanded descriptions, and details below each show so viewers can find out about the episode that's on more easily. For a few more details on what's new and refreshed, check after the break.
Image
That enhanced menu also includes the 1-5 star ratings for each show that ideally will help it improve the listings over time. If your favorites are mostly on one channel, then they can also be added as a Favorite, so all of that channel's shows will be in the list, all the time, or you can add shows and movies to the queue directly for easy access to them on streaming services. Finally, if you're at all interested in what everyone else is watching, the team has added a "Trending this week" list culled from Google searches. Judging by the usual trends on Twitter, we'll get our TV suggestions elsewhere, but it is an interesting parallel to the data already being collected and reported by companies like TiVo and GetGlue. We don't know if Google will dive headfirst into the TV ratings business, but with enough data anything is possible. As we get ready for the second generation of Google TV hardware to launch however, the first hurdle will be improving the user experience enough that it convinces customers to buy in this time around.

Google-backed research looks to fight fake reviews

http://cdn4.digitaltrends.com/wp-content/uploads/2012/03/Google-toys-around-with-the-Android-Market-changes-name-to-Google-Play.jpg


User reviews have become some of the most important pieces of information that exist on the Internet, but more importantly on mobile devices. We rely on user reviews to help us pick restaurants in Yelp or Google Maps, or get the best apps, music, videos, and books in the Google Play Store, iTunes App Store or Windows Phone Marketplace. Unfortunately, fake reviews are a growing problem without a clear solution.

Google wants to find a solution though, so the company has helped to fund research at the University of Illinois at Chicago. The trouble is that noting fake reviews is a pretty easy task, according to the researchers, but it's an incredibly difficult job to do with an algorithm.
The research team has presented a possible solution in the form of an algorithm called GSRank, which was created to target the behavior behind review fraud rather than the identity of the offender. The algorithm looks to catch fraud through a number of key fingerprints from groups of reviews including the time they were posted, the similarity of review/rating, the group size, and of course when the reviews were posted, because reviews posted too quickly in the life of an app tend to be fake. 

Of course, this research and the subsequent filtering from GSRank could be a huge boon to any app store, though it is likely the Google Play Store would get the benefits since Google backed the research. It would definitely help us find the best content, and also help businesses avoid any potential problems from negative fake reviews.

Η Google θέλει να καταπολεμήσει τα ψεύτικα reviews στο Google Play

Google Play Screenshots
Τα ψεύτικα ή στημένα reviews σε εφαρμογές του App Store ή του Google Play είναι ένα ολοένα και αυξανόμενο πρόβλημα στις πλάτες των developers που βλέπουν την επιτυχία των εφαρμογών τους να εξαρτάται σε έναν μεγάλο βαθμό από τα θετικά reviews. Όλοι μας πριν αγοράσουμε μια εφαρμογή ρίχνουμε μια ματιά στα reviews και στην βαθμολογία της εφαρμογής και αν δεν είναι θετική το σκεφτόμαστε διπλά. Τι γίνεται, όμως, όταν τα reviews αυτά είναι ψεύτικα;

Το πρόβλημα έρχεται να λύσει έρευνα του Πανεπιστημίου του Illinois στο Chicago που χρηματοδοτεί η Google. Ουσιαστικά, η εύρεση των ψεύτικων reviews είναι μια σχετικά εύκολη και απλή διαδικασία αλλά η αυτοματοποίησή της με έναν αλγόριθμο είναι αρκετά δύσκολη. Η ομάδα κατάφερε, ωστόσο, και δημιούργησε έναν αλγόριθμο με το όνομα GSRank που στοχεύει στη συμπεριφορά πίσω από τα ψεύτικα reviews παρά στην ταυτότητα του παραβάτη. Ο αλγόριθμος συνδυάζει στοιχεία όπως ο χρόνος δημοσίευσης, η ομοιότητα του review και της βαθμολογίας κτλπ για να καθορίσει την εγκυρότητα του σχολίου.
Προφανώς, ο αλγόριθμος αυτός θα μπορούσε να χρησιμοποιηθεί σε οποιοδήποτε app store αν και εξαιτίας της χρηματοδότησης το Google Play είναι, ίσως, το πρώτο που θα το εφαρμόσει. Σε οποιαδήποτε περίπτωση αυτοί που ωφελούνται είναι οι τελικοί χρήστες που θα κρίνουν βάσει αξιόπιστων reviews αλλά και οι developers που δεν θα πλήττονται από αρνητικά σχόλια που σκοπό έχουν να εξαπατήσουν.
