WhatsApp temporarily blocked again in Brazil

WhatsApp



The hugely popular WhatsApp smartphone messaging service was briefly blocked by a Brazilian court Tuesday for the third time in less than a year after failing to surrender user data to police.
The latest drama ended after the Supreme Court president, Ricardo Lewandowski, accepted an appeal against a lower court order that shut down the service nearly four hours earlier.

“The suspension of service apparently violates the fundamental precept of freedom of expression and communication,” the Supreme Court said, adding that Lewandowski found that the lower court judge’s decision seemed “not very reasonable and not very proportional.”


WhatsApp gradually resumed normal service after the high court’s ruling.

This had been the fourth court-ordered suspension of WhatsApp, which is owned by social media giant Facebook, since February 2015 and the third in the last 12 months.

The long-running dispute pits Brazilian authorities’ insistence that they need access to communications between alleged criminals against Facebook’s argument that it is protecting privacy and freedom of communication.

In the last incident, in May, the blockage lasted a day before being lifted on appeal.

The shutdowns have angered users reliant on the free app. Cell phone fees for texting and calls are high in Brazil and WhatsApp’s group chat and image-sharing functions have become embedded in everyday social interaction.

“We hope that this puts an end to blocks that have punished millions of Brazilians and that people can continue using services like WhatsApp to stay in touch with those who matter to them,” the company said in a statement.

– Nationwide block –
Earlier, lower court Judge Daniela Barbosa had ordered telecom companies to put an immediate nationwide stop to WhatsApp services.

Barbosa blasted Facebook as irresponsible for refusing “to provide information that will be critical to the success of an investigation and later to bolster the criminal case.”

It was not clear what was involved in the criminal case, but Barbosa said Facebook had been issued with three requests to provide messages to police investigators in Duque de Caxias, north of Rio de Janeiro. The 19-page court ruling said Facebook must comply or face fines of 50,000 reais ($15,265) a day.

WhatsApp was defiant, calling the order an “indiscriminate” threat to “people’s ability to communicate, to run their businesses and to live their lives.”

The company said it hoped “to see this block lifted as soon as possible.”

– Judge’s anger –
Billionaire Facebook CEO Mark Zuckerberg called the May shutdown “very scary in a democracy.”

But in the latest ruling, Barbosa criticized Facebook’s attitude, saying the company responded to Brazilian police with its own list of questions demanding explanations, adding that these were made in English, as if Brazil were “some small republic.”

The judge said those mourning the loss of WhatsApp “should remember that the main victim of the crimes being investigated is society itself, with the certainty that all the time, new victims are being created and new crimes are being committed while the judiciary is unable to stop the incidents or punish those responsible.”

WhatsApp responded in its statement that it doesn’t comply in revealing the encrypted communications because “we cannot share information we don’t have access to.”

WhatsApp is estimated to be used by 100 million Brazilians, making Brazil the second biggest user country after South Africa, according to data cited by the court.

Removable or Non-removable battery smartphone, which one should I go for?


It has always been such a never-ending struggle when it comes to choosing the right smartphones that meet both your needs and your budget. And the confusion is high when we are asked whether removable battery phones or non-removable is better for our phones. Let’s break this commonly-asked question into smaller aspects to easily compare.


1. Durability factor: Removable battery phones win

Personally, durability is the factor I value the most when choosing a smartphone, or a smartphone battery. Imagine your smartphone (which is not waterproof) falls into the water. The fastest way to save it is to immediately take out the battery and dry it out. In this case, removable battery phones clearly lead the game. Another situation to take into consideration is a ruined battery. After a certain time of usage, your smartphone battery life decreases considerately. And if you are not ready to buy a new one, changing the power cell could solve the problem. On tech forums, users and experts are even claiming that, many companies nowadays go for non-removable when producing their mobiles in order to boost sales record.


Unfortunately, users of non-removable battery smartphones know the pain when similar accidents happen. They have to either be super cautious with water damage, or apply all the tips to keep the lifespan as long as possible. However, they do have their own strength in this battle: non-removable batteries are far more dust resistant than its counterpart. Also, many people love the appealing slim body those smartphones have when the battery doesn’t take much place.



2. Overheating and frozen problems: removable battery phones win

Back in the days when most mobiles are removable battery phones, we all remember the instruction “In case of any heating problem, remove your battery”. This way, you can let the power cell chill down a bit before having it work again. In addition, when your mobile falls into to “force to stop” or “frozen” states, which happens quite frequently, casually removing the battery can save the day. With a non-removable machine, although you can switch off and restart, it is far less effective than taking out the cell.



3. Reselling matter: removable battery phones

Similar to the first factor, a removable battery phones get easily replaced when old or damaged. This makes these mobiles more possible to sell, even at a higher price. The explanation for this is clear: a second-hand buyer would prefer to have a decent machine that can work a for a certain amount of time without having to worry about recharging. This also assures them that, as long as the processor still runs smoothly, battery is a solvable issue because you can always buy a new one any time its performance starts to reduce.


That being said, considering these 3 most common aspects of a power cell, removable battery phones clearly have more advantages than its counterpart. The only drawbacks we found are dust resistant and not-so-slim design. As a user, which among the two would you prefer to choose for yourself?

Obi robot arm gives disabled diners a helping hand




Robotic cooking aids are gaining traction in the modern kitchen, but the team behind Obi has a goal more noble than just cooking up a gourmet storm. This little robot arm is designed to empower people afflicted with physical disabilities, giving them back the dignity of feeding themselves.

Obi comes with two interchangeable spoons, a large and a small, that attach to the arm...
Obi's plate contains four separate bowls, which allows users to decide which food they want in...
Users control Obi through two simple commands: move the arm to the next bowl, and bring...
A "Teach Mode" button allows a caregiver to set the exact location for the arm to...

The first product out of consumer robotics company Desin, Obi looks like a clean, modern kitchen appliance that could improve the quality of life for sufferers of conditions such as ALS, cerebral palsy, MS, Parkinson's and brain or spinal injuries. After a caregiver divides the meal into Obi's four separate bowls, users are able to feed themselves through a simple interface: one button moves the arm between the bowls, and another selects that food, dips the spoon in and brings it up to the diner's mouth.



Those inputs can be customized, depending on the specific needs and abilities of the user. Big bright "Buddy Buttons" on the table can be useful for those who still have some function in their hands but lack the fine motor skills required to steady a spoon. They could also be placed on the floor to use as foot pedals. Pillows that respond to the slightest squeeze allow for head and cheek activation, while a small mouth piece switch can be triggered through sip or puff actions.

A "Teach Mode" button allows a caregiver to set the exact location for the arm to...
How does Obi know where the user's mouth is? There's a "Teach Mode" button where the arm can be positioned manually to the desired location. From then on, the robot will remember that position and return to it any time the user presses the button, until a new one is set.

Collision detection prevents Obi from charging straight onto that position if a wayward eye or hand happens to cross its path. When dinner's all done, Obi's plates and spoons, which are BPA-free, can be thrown in the dishwasher, microwave or freezer. Desin says the device will provide two to four hours of eating time for each charge of its internal batteries.


Obi's available for US$4,500, which includes the plate, placemat, a large and small spoon, charging cable and user documentation. The "Buddy Buttons," pillows and mouth piece can be ordered separately, depending on user needs.

Google launches final Android Nougat Developer Preview




Google today released the fifth and last preview Android Nougat before the scheduled final release later this summer.

According to the company, this preview includes the latest version of the Android Nougat emulator to do apps final testing, the final N APIs, the latest system behaviors and UI and the latest bug fixes and optimizations across the system and pre-installed apps. As far as we know, there are no new user-facing features in this release, though Google has occasionally made minor tweaks to the user interface between developer previews.


The Nougat Developer Preview is now available for Nexus 6, Nexus 5X, Nexus 6P, Nexus 9 and Pixel C devices, as well as General Mobile 4G Android devices (both in the form of over-the-air updates and system images).


To get the preview, no action is needed if you are already enrolled in the Android Beta program: Your devices will get the Developer Preview 5 update automatically. If you aren’t yet enrolled in the Android Beta program, you can still visit android.com/beta and opt-in your eligible Android phone or tablet. You also can download and flash this update manually.

“This preview gives developers the near-final system updates for all of the supported preview devices,” the company wrote in a blog post.

The name for Android 7.0 was chosen by fans after an online survey. As usual, since the release of Android Cupcake, each version of the mobile operating system is named after something sweet: “Nougat” is a confection made with sugar (or honey) that usually contains nuts.

Google hangout gets video messaging support




Two years after hangout for iOS got the video messaging
feature, Google has finally rolled out the video messaging
feature on the Android version of Hangout.

Basically, the video messaging feature on hangout isn’t a
video calling service like Skype (it already has the video
calling feature locked down). However, it does pretty much
what it’s intended to do. And that’s the ability for users to
record and send videos to other users.

While that sounds interesting but isn’t new, the video
feature on hangout is limited to one minute in duration. Not
only can you record and send videos, users can equally
send already recorded videos which could mean videos
from the device’s gallery.

Although the feature isn’t too late (maybe), the feature is
quite odd in the sense that, Google usually rolls out new
features on its Android platform before iOS. And Android
users had to wait for over 2 Years before getting a feature
that’s been on iOS version of a Google app.

Months before, the hangout version on iOS could only
record and send 10 second videos but that was upped a few
months back to a minute. Same video length Android
hangout users can utilize now.

As a consolation, the iOS version of Hangout can only
record and send videos in 360p quality while Android users
can record and send in 1080p FHD quality.

Another news worthy of mention is that Google recently
unveiled two messaging apps; Allo (hello) and Duo. One
being an assistant app and the other being a video calling
app. Hence, Hangout for Android just getting video
messaging support may not be much of a biggy. But then
again, it’s better late than never.

Why a Quad-Core Processor May Be Faster Than an Octa-Core Processor


To dominate the mobile market, OEMs now go into specifications war, beefing up their devices’ specifications every year. Their marketers capitalize on consumers’ ignorance, selling lies and making money off them. Sadly, this trend will continue until consumers know the technicalities behind these things. However, it’s a known fact that this will never happen; OEMs will continue with these gimmicks while consumers keep getting fooled.


Take camera resolution for example, a lot of consumers would rather go for a phone with 21MP camera with only f/2.8 aperture instead of a 12MP camera with f/1.8 aperture and OIS. This is because they believe that the 21MP camera would produce better pictures. These huge numbers do not always matter.

An octa-core processor is not always better than a quad-core processor.


While a lot of consumers have an idea of what processors do and how they contribute to the overall efficiency of a smartphone, many do not realize that an octa-core processor is not always better than a quad-core processor.

An octa-core processor has 8 cores, with a quad-core processor having
just 4 cores. Since more is better, anyone would think a device with 8 cores is the real deal.





What these cores mean


Your processor is the Central Processing Unit that processes everything that happens on your device. Whether you are surfing the web, opening a file, scrolling through pages, the processor is meant to process information. The reason it’s called a processor is because it processes everything. It’s as simple as that.


Without going into techy details like memory cache, ALUs, instruction pipeline, I/O control hardware and the rest, it becomes easier to understand when when the processor is seen as the Central Processing Unit, and the cores are seen as processing units within the CPU.


Having 8 cores is like having 8 people in a room working for you.
However, it should be noted that not all these 8 cores are employed at once. As a matter of fact, most applications make use of one or two cores at a time. One might argue that games need all these cores, but this is why a GPU (Graphic Processing Unit) is there to work with the CPU.


Most of the time, the other cores are just there, doing nothing. A well-coded application should never demand all cores to work. This will take a heavy toll on the battery.


What makes a good processor?


The number of cores, right? This contributes to the overall efficiency of a processor, but it’s not even the most important.

Clock rate: This is the frequency at which the processing units or cores are running. This is normally used to indicate a processor’s speed. A 1.3GHz octa-processor cannot be compared with a 2.0GHz quad-core. The quad-core may beat the octa-core processor in single-core processing multi-core processing.


Still OEMs put 1.2GHz octa-processors on devices and make it sound like a great thing.


Architecture: Qualcomm, MediaTek, Samsung, nVidia and other companies manufacturing chipsets for mobile phones use ARM’s design and circuitry on how a processor should be built. The manufacturers use ARM’s reference design and there are different versions. A newer architecture like ARM Cortex-A73 will surpass an older architecture like ARM Cortex-A5 in performance
There are many other factors which this article will not be able to cover.





Stop focusing on the number of cores

The fastest mobile chipset in the world right now has only 4 cores, and that’s Qualcomm Snapdragon 821 . Using the big.LITTLE configuration, two processors are clocked at 2.4GHz while the other two are clocked at a lower frequency of 2.0GHz.


Next time you’re picking a phone off the shelf, it’s not always about the number of cores the processor has, be more concerned about the clock rate and architecture. OEMs will make you believe 8 cores is always better, but your phone is not really going to need them all.
And by the way, the iPhone 6s has just a dual-core processor, and it’s still one of the top 10 fastest mobile devices in the world .

Playing Pokémon Go in Nigeria.


It's safe to say Nintendo's hit mobile game Pokemon Go is more suited for playing in the clean, well-lit streets of San Francisco or the impeccably-maintained parks of New York.


Anarchic Lagos on the other hand, with its seemingly suicidal motorcyclists, festering sewage and prowling thieves, doesn't appear to be the ideal place to go hunting virtual creatures.


But some locals in the West African megacity think nothing of braving the chaos to catch them all.
"Here it's like Mad Max, you've gotta be sharp or else there will be some injuries," Timi Ajiboye, a 23-year-old software developer, told AFP.


"Sometimes it's just not safe to bring out your phone. If you do, thieves will come at you like flies," added Ajiboye's younger brother Tade.


Playing may be dangerous yet Nigeria has its perks, insisted the 19-year-old electrical engineering student at the University of Lagos.


"There's so much rare Pokemon here because it's not a mainstream country," Tade said. "Fortunately for me, I live here."


The 19-year-old explained that he's seen "quite a few Bulbasaur" though hasn't been able to catch the green dinosaur-like species since "they are very stubborn".
Like many other players around the world, the Ajiboye brothers found a way to download the game when it was released early this July, despite it being officially available only in the United States, Australia and New Zealand.


The enthusiastic uptake is a sign of the mobile revolution happening in Nigeria, which is Africa's largest mobile market.


Companies have committed to 3G coverage in 90 per cent of the country and are starting a fibre network roll-out in six cities, according to Bloomberg News.

Samsung made a limited edition Galaxy S7 Edge for the Olympics




The Galaxy S7 Edge is one of this year's best
phones, so why not give it to some of the world's
best athletes? Apparently the Batman phone
wasn't enough, as Samsung is churning out yet
another special edition of its curved smartphone —
this time to celebrate the upcoming Olympic
Games in Rio. This unlocked version of the S7
Edge will be gifted to everyone participating in the
games, but it's also coming to stores next month.
Well, one store: Best Buy. The big box retailer has
exclusive dibs on sales for this one. Pricing isn't
yet final, but the regular S7 Edge is by no means
cheap, so the Olympic Games Edition won't come
cheap.


So what separates this from the Galaxy S7 Edge
that's been on shelves for months? Just like the
Batphone, it's really all aesthetics. The metal sides
are black and glossy, which feels quite different in
hand compared to the regular model. And then
there are the buttons. Samsung has customized
the accents for each hardware button to
correspond with the Olympics rings. The home
button and earpiece are yellow, the power button
is red, the volume rocker is green, and there's a
blue bezel around the camera. It looks a little
funky! But it makes more sense when you realize
what the phone commemorates.



Sadly, Samsung isn't tossing in a Gear VR this
time. So you lose out on the really sleek, all-black
VR headset that came with the Batman edition.
Perhaps Samsung figures athletes are too busy
training to spend much time getting lost in VR. Oh
well. You do get a nice (though rather large)
carrying case alongside the phone. And that's
pretty much it. The Olympic Games Edition is just
another new coat of paint for Samsung's flagship.
It's free swag for Olympians, and yet another
thirsty marketing tactic for the company to get its
brand front and center in Rio. If you're a fan of the
color scheme, you'll be able to buy it from Best
Buy beginning in August. And since this is the
unlocked model , it should work on all the major
US networks.
