Flipkart teases upcoming Moto E will go on sale on May 14

Tags: Motorola , Android

We practically know everything about the Motorola Moto E now. The companys newest Android smartphone is expected to slow below the already low-priced Moto G.

Indian online retailer Flipkart, which has exclusive rights to sell the Moto G and Moto X in India, has now started teasing the Moto E on their social media accounts.

The teaser images dont mention the name but the outline of the phone matches all the leaked images we have seen. Flipkart is also suggesting replacing low-end feature phones with the Moto E, indicating a very low price point. The website says 4 days to go for the new Moto, meaning the phone will go on sale on May 14, even if the actual launch is on May 13.

You can read our post for images and specifications of the Moto E.

Samsung Galaxy S5 launches on NTT DoCoMo Pink color in tow

Tags: Samsung , NTT DoCoMo , Android

The Samsung Galaxy S5 has reached the land of the rising sun – the flagship went on sale on the countrys biggest carrier, NTT DoCoMo. This launch also debuts a new color, Sweet Pink, in addition to the standard Charcoal Black and Shimmering White (the Copper Gold and Electric Blue are not available though).

Anyway, the Samsung Galaxy S5 SC-04F is virtually the same as the international version, except for some country and carrier-specific additions. Those are mostly in the connectivity section with Xi LTE (150Mbps downlink), VoLTE (voice over LTE networks), FOMA, 1Seg and NOTTV (mobile TV standards).

The SC-04F also features fast and quick charging – they require dedicated chargers, but they can put 1,200mAh and 1,800mAh in the battery respectively in just an hour. The international Galaxy S5 doesn’t have this feature.

Anyway, the phone will be available tomorrow, May 15, but you can pre-order it right now from NTT DoCoMos web site.

By the way, NTT DoCoMo also launched the Sony Xperia A2 today.

Do i need to pay if i have WIFI connectivity when i make video calls on Galaxy note 2

Q. just bought my note 2 & im overseas. i make video calls thinking that it should be equivalent to facetime of iphones but seems the person (also using samsung model) im calling can see my phone no. does it mean im using my own call time? Thanks

A. If your connected to wifi you dont have to pay

Original Question

Is the Samsung Galaxy Note 2 good for everyday use?

Q. Im worried that it might be too big for everyday use, and will it fit in my pocket?

Thanks :)

A. Its absolutely perfect for your everyday needs. The big display and huge battery will make it good for heavy use as well. And dont worry about pocketing the phone. It will fit you just fine.

Original Question

Why is my Galaxy Note 2 battery draining on standby.?

Q. So before I go to bed my Phone would be 100% When I wake up its around 75-80% I turn the Wifi off and bluetooth also I tone down the brightness. Do you have an app to solve this problem?

A. Have you closed most of your opened apps on your device? Opened apps may drain battery.

Im also wondering, that the battery meter on your phone has gone out of sync with the actual battery power. Here you can find how to fix the problem:

The discussion is for the Kindle Fire, but the same principle will work for any Android devices.

Developer Insights Teaching thousands of students to program on Udacity with App Engine part 2

This post is the second of our two-part series discussing how Udacity uses Google App Engine.

Today’s guest blogger is Chris Chew, senior software engineer at Udacity, which offers free online courses in programming and other subjects.  Chris shares how Udacity itself is built using App Engine.

Steve Huffman blogged yesterday about how App Engine enables the project-based learning that makes his web development course so powerful.  People are often surprised to learn that Udacity itself is built on App Engine.

The choice to use App Engine originally came from Mike Sokolsky, our CTO and cofounder, after his experience keeping the original version of our extremely popular AI course running on a series of virtual machines.  Mike found App Engine’s operational simplicity extremely compelling after weeks of endlessly spinning up additional servers and administering MySQL replication in order to meet the crazy scale patterns we experience.

Close to a year later, with ten months of live traffic on App Engine, we continue to be satisfied customers.  While there are a few things we do outside App Engine, our choice to continue using App Engine for our core application is clear:  We prefer to spend our time figuring out how to scale personalized education, not memcached.  App Engine’s infrastructure is better than what we could build ourselves, and it frees us to focus on behavior rather than operations.

How Udacity Uses App Engine

The App Engine features we use most include a pretty broad swath of the platform:

• High Replication Datastore with NDB


• Memcache


• Task Queues - Deferred execution, MapReduce, batch jobs


• App Engine Search API -- Indexing both course content and student résumés


• Blobstore API -- Lecture videos, résumés, data exportation


• Image API - Thumbnail generation


• MapReduce API - Daily usage analytics, data migrations, data maintenance

A high-level representation of our “stack” looks something like this:

Trails and Trove are two libraries developed in-house mainly by Piotr Kaminski.  Trails supplies very clean semantics for creating families of RESTful endpoints on top of a webapp2.RequestHandler with automagic marshalling.  Trove is a wrapper around NDB that adds common property types (e.g. efficient dereferencing of key properties), yet another layer of caching for entities with relations (both in-process and memcache), and an event “watcher” framework for reliably triggering out-of-band processing when data changes.

Something notable that is not represented in the drawing above is a specific set of monkey patches from Trove we apply to NDB to create better hooks similar to the existing pre/post-put/delete hooks.  These custom hooks power a “watcher” abstraction that provides targeted pieces of code the opportunity to react to changes in the data layer.  Execution of each watcher is deferred and runs outside the scope of the request so as to not increase response times.

Latency

During our first year of scaling on App Engine we learned its performance is a complex thing to understand.  Response time is a function of several factors both inside and outside our control.  App Engine’s ability to “scale-out” is undeniable, but we have observed high variance in response times for a given request, even during periods with low load on the system.  As a consequence we have learned to do a number of things to minimize the impact of latency variance:

• Converting usage of the old datastore API to the new NDB API


• Using NDB.tasklet coroutines as much as possible to enable parallelism during blocking RPC operations


• Not indexing fields by default and adding an index only when we need it for a query


• Carefully avoiding index hotspots by indexing fields with predictable values only when necessary (i.e. auto-now DateTime and enumerated “choices” String properties).


• Materializing data views very aggressively so we can limit each request to the fewest datastore queries possible

This last point is obvious in the sense that naturally you get faster responses when you do less work.  But we have taken pre-materializing views to an extreme level by denormalizing several aspects of our domain into read-optimized records.  For example, the read-optimized version of a user’s profile record might contain standard profile information, plus privacy configuration, course enrollment information, course progress, and permissions -- all things a data modeler would normally want to store separately.  We pile it together into the equivalent of a materialized view so we can fetch it all in one query.

Conclusion

App Engine is an amazingly complete and reliable platform that works astonishingly well for a huge number of use cases.  It is very apparent the services and APIs have been designed by people who know how to scale web applications, and we feel lucky to have the opportunity to ride on the shoulders of such giants.  It is trivial to whip together a proof-of-concept for almost any idea, and the subsequent work to scale your app is significantly less than if you had rolled your own infrastructure.

As with any platform, there are tradeoffs.  The tradeoff with App Engine is that you get an amazing suite of scale-ready services at the cost of relentlessly optimizing to minimize latency spikes.  This is an easy tradeoff for us because App Engine has served us well through several exciting usage spikes and there is no question the progress we have already made towards our mission is significantly more than if we were also building our own infrastructure.  Like most choices in life, this choice can be boiled down to a bumper sticker:

Editor’s note: Chris Chew and Steve Huffman will be participating in a Google Developers Live Hangout tomorrow, Thursday, November 1st, check it out here and submit your questions for them to answer live on air.

Millionaire UBS CEO Wants Everyone To Stop Picking On Banks For Being Unethical

(twicepix)

Listen, you guys. We know it makes you feel better to pick on banks for all those ethically dicey financial things like manipulating interest rates and making other questionable decisions. But the CEO of UBS wants you to cut it out, because while sticks and stones may break his bones, words will never hurt him. Sniff. Sniff.

Europe has been in the midst of a financial crisis for some time now and as such, banks are hearing a whole lot of frustrations from the public and investors. But apparently banks have been just biting their tongues and taking it. Until now.

Sergio Ermotti is the head of UBS and it sounds like his feelings have been hurt by all bank-bashing going on, reports the Wall Street Journal.

“Life is hard enough, and I think this constant lecturing on ethics and on integrity by many stakeholders is probably the most frustrating part of the equation. Because I don’t think there are many people who are perfect,” Ermotti said in an interview at the World Economic Forum in Davos, Switzerland. “We are far from being perfect…but it’s not going to be very helpful to be constantly bashing banks.”

Yes, life must be very hard for a millionaire CEO. But it sounds especially rough for Ermotti’s UBS, which has suffered huge losses in the wake of the financial crisis in Europe, as well as regular lambasting for things like its role in manipulating benchmark interest rates and a rogue-trading scandal.

Last May UBS provoked the wrath of angry shareholders at the annual meeting due to the comfy pay packages management was receiving even after a $2.7 billion loss.

Many believe tempting bonus packages are partly to blame for bankers making risky investments they might not otherwise make. Packages like the $26 million “golden hello” UBS paid Ermotti in 2012, the same year it fired 10,000 employees in a “cost-cutting” effort, the Financial Post previously reported.

Ermotti has been busy trying to clean things up at the bank since he arrived on the job in 2011, but it sounds like he’s having a tough go of it, due to those pesky shareholders. It’s not like anyone else is doing any better, he insists.

“When I look around, I don’t think there are many banks that can come to us and say they are the example that should be followed,” he said. And besides, the banks aren’t to blame for Europe’s economic troubles, he says.

“It’s just an absurd concept. We all see that by now it’s a little more than a financial crisis,” he explained. It’s just that the banking industry “is an easy target.”

Besides, all those troubles piling up on UBS’ and others’ doorsteps is due to just a couple of employees going rogue, and shouldn’t reflect on the industry itself.

“It’s not because you’re a banker that you’re a criminal,” he said.

Oh okay — so it shouldn’t up up to banks to get investors and the general public to trust them again. We’ve just all got to stop punishing the industry because its feelings are hurt. Got it.
