Twitter CEO gives up $200M in stock for company employees

SAN FRANCISCO (AP) — After laying off more than 300 workers,Twitter CEO Jack Dorsey is trying to lift the spirits of the remaining employees by giving them 6.8 million shares of the stock he owns in the online messaging service.

Dorsey is giving up the stock, currently worth more than $200 million, so Twitter can award the shares to its employees, according to documents filed Friday with the Securities and Exchange Commission.

The gesture comes a week after Dorsey laid off 8 percent of Twitter's workforce in an effort to make the company profitable for the first time in its nine-year history. The gift represents nearly one-third of the stock Dorsey owns in the San Francisco company.

Online Gaming Is The New Social Network

We speak to one avid online gamer about how the medium is replacing traditional social media.

Harrison, 16, reveals how a new generation is turning to Xbox and PlayStation as a way to stay in touch with friends and meet new people.

Harrison says: Online multiplayer gaming is like Facebook, but there are far more things to do. It’s just a more entertaining way to be in touch with people.

It’s a great way to stay in touch with my friends and I’ve also made new friends in games who I’ve go on to meet away from the screen.

It’s no longer just entertainment. It’s a new kind of experience. Online gaming on PayStation 4 or Xbox One basically IS a social network. I can instantly see what my friends are up to, and choose whether or not to join in.

When we ‘meet up’, we don’t just shoot each other. There’s lots of ways to interact in online games, whether it’s just sending a message or actually making some sort of in game gesture. Even something stupid like dancing.

If I do something amazing in game, I can also share pictures and video direct to Twitter or Facebook which makes the whole experience even more ‘social’.

Although I will play almost any game, I play online games more than any others. It’s just more satisfying and enjoyable to play with a human being rather than a computer.

When it comes to playing against the computer it’s easy to get bored. If it’s a real person there, it keeps you interested.

Games without multiplayer aren’t over, though. There are just new ways to play. There are plenty of games where you are playing a single-player story, but there just happen to be other people around.

'Destiny' is a good example. You never have to shoot your mates if you don’t want to.

'Destiny' is online right from the very beginning, but you have the option of completing the game by yourself or with others. It’s a great way to stay connected with people. Personally, I really enjoy that way of playing.

I know some people might find it odd, but it’s totally normal for me to wear a headset while playing and talk to other gamers - both people I know and people I don’t.

If someone is sending you a text message, it’s usually because either they don’t know you or their headset has broken and they are waiting for a new one. I think most online players will be able to relate to this!

Microsoft just unveiled its first laptop — and it says it's twice as fast as a Macbook Pro

microsoft surface book

(Screenshot) Microsoft on Tuesday unveiled its first laptop: the Microsoft Surface Book, a 13-inch touch-screen device that also comes apart to become a tablet.

"This is the ultimate laptop," Microsoft's Panos Panay said.

It has two processors and a dedicated graphics-card system. Microsoft says the laptop is twice as fast as a Macbook Pro.

Pricing starts at $1,499, and the laptop will be available on October 26.

As with all devices in the Surface line, the Surface Book can detach from its keyboard to become a tablet. The keyboard can then dock on the back of the tablet to keep it all together. It also uses the Surface Pen stylus that comes with Surface tablets.

Microsoft Surface Book

(Microsoft) The Surface Book has a unique hinge.It's designed to add more power than the Surface Pro 4, also announced Tuesday. It's for gamers and any enterprise worker who needs more graphical horsepower under the hood. In fact, the Xbox team contributed its graphical expertise, Panay said.

Panay showed off how smoothly Windows 10 games like "Gears of War" and "Gigantic" ran on the Surface Book, even while using video-editing software to record game footage.

Interestingly, the graphics card lies in the keyboard unit, which means you will lose some horsepower while it's unplugged — at a likely gain to battery life.

Plus, it has a super-quiet, backlit keyboard, Microsoft promises, with a great typing experience. It also sports a promised 12-hour battery life.

The idea of a laptop that's also a tablet isn't exactly new: PC manufacturers like Lenovo have for some time been making similar "convertible" units that fold in on themselves to become a laptop.

But by making the keyboard detachable, and by giving it a ton of horsepower, it seems Microsoft has been really thinking through the design of this device.

Reviewed: The Thinnest, Loveliest MacBook You’ll Never Buy

It’s so easy to blast Apple for sacrificing utility in the name of beautiful design. Everybody does it every time a new Apple product comes out.

The iPhone, 2007: “No keys! No memory card! No removable battery! Doomed!”

The MacBook Air, 2008: “No DVD drive! No hard drive! Doomed!”

The iPad, 2010: “No USB ports! No expansion! Doomed!”

But time passes. The tumult dies down, the product becomes a huge hit, and rival companies soon embrace exactly the same design.

This Friday, you’ll be able to buy the company’s latest product, the MacBook. Not the MacBook Air, not the MacBook Pro (both of which will remain for sale). Just MacBook.

Yes, the cycle of “Doomed!” is about to begin again. I know this cycle too well. I’ve lived through it over and over. And even so, this time, when I behold this new 12-inch MacBook, I want to shout: “This time, you’ve really gone too far!”

I mean, no jacks at all!?

That’s correct. No standard USB jacks, no video output jacks, no memory card slot, no Thunderbolt port, no Ethernet.

On top of all that, Apple has the gall to introduce another MacBook power connector. With this model, Apple has abandoned the MagSafe connector (both versions of it), the magnetic charging plug that doesn’t drag your laptop to the floor when someone trips on it. 

When Apple unveiled MagSafe, Steve Jobs hailed it as a triumph of clever engineering and common sense. And now suddenly MagSafe is dropped like chopped liver.

Meet the MacBook

OK, well, that’s the bad news.

The good news is that this laptop looks amazing. It is crazy thin, light, and small. It’s available in three aluminum hues (a first for Apple) — standard silver, gold, and gray. The gray looks wicked great.

New aluminum battery for smartphones can be charged in a minute

Reuters

April 7, 2015

LONDON (Reuters) - U.S. scientists said they have invented a cheap, long-lasting and flexible battery made of aluminum for use in smartphones that can be charged in as little as one minute.

The researchers, who detailed their discovery in the journal Nature, said the new aluminum-ion battery has the potential to replace lithium-ion batteries, used in millions of laptops and mobile phones.

Besides recharging much faster, the new aluminum battery is safer than existing lithium-ion batteries, which occasionally burst into flames, they added.

Researchers have long tried but failed to develop a battery made of aluminum, a lightweight and relatively inexpensive metal that has high charging capacity.

A team lead by chemistry professor Hongjie Dai at Stanford University in California made a breakthrough by accidentally discovering that graphite made a good partner to aluminum, Stanford said in a statement.

In a prototype, aluminum was used to make the negatively-charged anode while graphite provided material for the positively charged cathode.

A prototype aluminum battery recharged in one minute, the scientists said.

"Lithium-ion batteries can be a fire hazard," said Dai. "Our new battery won't catch fire, even if you drill through it."

The new battery is also very durable and flexible, the scientists said.

While lithium-ion batteries last about 1,000 cycles, the new aluminum battery was able to continue after more than 7,500 cycles without loss of capacity. It also can be bent or folded.

Larger aluminum batteries could also be used to store renewable energy on the electrical grid, Dai said.

How to Do a Word Search on Webpages with iPhone and iPad

Yoni Heisler, BGRApril 2, 2015

If you’re an iPhone or iPad user, odds are that you use mobile Safari to do all of your web browsing. But buried underneath all all of the more overt browsing options is a hidden way to search an individual webpage for a specific word or phrase.

Here’s how you can find it and use it to your heart’s content.

DON’T MISS: Dual-core iPhone 6 graphics performance crushes Samsung’s octa-core Galaxy S6

Let’s say I hop on over to NBA.com and want to quickly scan the page for any stories involving, say, Kevin Durant. Instead of tediously scrolling through the entire webpage and hoping to spot a story of interest, iOS provides a clever way to do all of the heavy lifting for you.

To get started, simply apply a single tap to the URL bar, highlighted below.

Once the URL bar becomes highlighted, you can begin typing in your search phrase which, in this case, is “Durant.”

Next, you’re presented with what appears to be a standard Safari search results page. Clearly these are of no help.

But here’s where things get cool.

Simply scroll further down on the page and you’re soon presented with a previously hidden category which lists out all of the instances in which “Durant” is found on the webpage in question.

Boom. There it is.

Following that, simply tap on “durant” and you’re whisked back to the NBA.com homepage and all of the instances of “Durant” on the open page will be highlighted in yellow. What’s more, iOS makes it easy to navigate between each instance of the word simply by tapping the arrow keys on the lower left hand side of the display.

For a feature that’s as useful and widely used as in-page search, one would think that Apple would advertise this functionality just a little bit more. Either way, this handy tip should help save some time you might otherwise spend searching and slogging through a massive webpage with tiny text.

How to boost your WiFi speed by choosing the right channel

How to boost your WiFi speed by choosing the right channel

Wireless networks have come a long way in the past 15 years. And yet, sustained WiFi speeds are still a vexing problem in a lot of situations. A number of things can come into play, such as the way your router is set up, whether there’s nearby interference, if you live in an apartment building or a separate house, and how far apart your devices are from the router. Fortunately, there’s always a way to fix slow transfer speeds.
If you’ve ever messed around with your WiFi router’s settings, you’ve probably seen the word channel. Most routers have the channel set to Auto, but I’m sure many of us have looked through that list of a dozen or so channels and wondered what they are, and more importantly, which of the channels are faster than the others. Well, it turns out some channels are indeed much faster — but that doesn’t mean you should go ahead and change them just yet. Read on to find out more about 802.11 channels, interference, and the massive difference between 2.4GHz and 5GHz WiFi.

Channels 1, 6, and 11

First of all, let’s talk about 2.4GHz, because as of the start of 2015, almost all WiFi installations still use the 2.4GHz band. 802.11ac, which debuted in 2013, is driving adoption of 5GHz — but thanks to backwards compatibility and dual-radio routers and devices, 2.4GHz will continue to reign for a while.

All of the versions of WiFi up to and including 802.11n (a, b, g, n) operate between the frequencies of 2400 and 2500MHz. These paltry 100MHz are separated into 14 channels of 20MHz each. As you’ve probably worked out, 14 lots of 20MHz is a lot more than 100MHz — and as a result, every 2.4GHz channel overlaps with at least two (but usually four) other channels (see diagram above). As you can probably imagine, using overlapping channels is bad — in fact, it’s the primary reason for awful throughput on your wireless network.
Fortunately, channels 1, 6, and 11 are spaced far enough apart that they don’t overlap. On a non-MIMO setup (i.e. 802.11 a, b, or g) you should always try to use channel 1, 6, or 11. If you use 802.11n with 20MHz channels, stick to channels 1, 6, and 11 — if you want to use 40MHz channels, be aware that the airwaves might be very congested, unless you live in a detached house in the middle of nowhere.

What channel should you use in a built-up area?

If you want maximum throughput and minimal interference, channels 1, 6, and 11 are your best choice — but depending on other wireless networks in your vicinity, one of those channels might be a much better choice than the others.
For example, if you’re using channel 1, but someone next door is annoyingly using channel 2, then your throughput will plummet. In that situation, you would have to change to channel 11 to completely avoid the interference (though 6 would be pretty good as well). It might be tempting to use a channel other than 1, 6, or 11 — but remember that you will then be the cause of interference (and everyone on 1, 6, and 11 will stomp on your throughput, anyway).
In an ideal world, you would talk to your neighbors and get every router to use channels 1, 6, or 11. Bear in mind that interior walls do a pretty good job of attenuating (weakening) a signal. If there’s a brick wall between you and a neighbor, you could probably both use channel 1 without interfering with each other. But if it’s a thin wall (or there’s lots of windows), you should use different channels.
There are tools that can help you find the clearest channel, such as Vistumbler, but it’s probably easier to just switch between channels 1, 6, and 11 until you find one that works well. (If you have two laptops, you can copy a file between them to test the throughput of each channel.)

But what about 5GHz?

Get ready for lots of antennas.

The great thing about 5GHz (802.11n and 802.11ac), because there’s much more free space at the higher frequencies, is that it offers 23 non-overlapping 20MHz channels!
It’s also worth pointing out that, starting with 802.11n, wireless technology in general is a lot more advanced than the olden days of 802.11b and g. If you own a modern 802.11n router (i.e. if you bought a router in the last couple of years), it likely has some fancy hardware inside that chooses the right channel and modifies the output power to maximize throughput and minimize interference.
If you’re using the 5GHz band, and your walls aren’t paper-thin, then attenuation and the general lack of 5GHz devices should mean there’s very little interference in your apartment — possibly even allowing you to use the fatter 40, 80, and 160MHz channels if you feel like it.
Eventually, as everyone upgrades to newer hardware and moves towards 5GHz, picking the right channel will mostly become a thing of the past. There may still be some cases where it makes sense to fine-tune your router’s channel selection. But when you’re dealing with MIMO setups (up to eight in 802.11ac), it’s generally a better idea to let your router do its own thing. Eventually, of course, 5GHz will fill up as well — but hopefully by then, we’ll have worked out how to use even higher frequencies (60GHz WiGig) or entirely new antenna designs (pCells, infinite capacity vortex beams) to cope with our wireless networking demands.

Asus Transformer Book T300 Chi review

Where Chi stands for compromise

Take a look at the side profile of your laptop. Chances are, it's anywhere from a half an inch to an inch thick, replete with a handful of USB ports, a power plug, headphone jack, and maybe an SD card slot. I can all but guarantee that it's thicker than the laptop I'm currently using to write this article, Asus' Transformer Book T300 Chi. The $699 T300 Chi ($899 as tested) is a sliver of a computer, closer in size to the average tablet than a full-blown laptop.
In fact, the T300 has a lot more in common with an iPad than an ultrabook. As with many Windows 8.1 machines, it's a convertible laptop, with a detachable keyboard and full touchscreen. But unlike many other convertibles, the T300's tablet portion is only 7.6mm thick and it doesn't have any full-size USB ports, HDMI ports, or SD card slots. Like Microsoft's Surface Pro 3, all of the T300's major components are crammed into the tablet area, including its 12.5-inch, 2560 x 1440 pixel IPS display, Core M processor, 8GB of RAM, and 128GB SSD. The Core M processor lets the T300 do away with the fans (just like Apple's upcoming new MacBook) and gives it that tablet-like profile. When attached to its Bluetooth keyboard, the T300 is still only 16.5mm thick, though the combined 3.14lbs of the two parts is more laptop-like than tablet-like.

In place of the standard ports you might expect to find on a laptop, the T300 has one Micro USB port, one Micro HDMI port, and a microSD slot hidden on its bottom edge. That means connecting any peripherals requires the use of adaptors, whether you just want to plug in a standard thumb drive, output video to an external display, or use a wired mouse. Those are the compromises that come with such a thin computer, and Apple's upcoming MacBook will require jumping through many of the same hoops.

But there are other compromises with the T300 that make it tough to use as a daily machine. The Bluetooth keyboard (which is included and matches the main computer's attractive, but fingerprint prone sapphire blue finish) offers a large layout, but the keys are shallow and don't have backlighting. The deck below the keyboard is very short and isn't enough to support my hands for long periods of time. And the trackpad, while responsive to both single and multi-touch gestures, is very small and tedious to use. The two halves of the T300 connect with magnets, but unlike the Surface Pro 3, they don't talk to each other through the attachment point. The keyboard communicates with the main tablet part strictly via Bluetooth, which means there is often an annoying delay as the keyboard wakes up and pairs with the tablet when I open the computer and type in my password. Further, the T300 Chi has a slight wobble when it's on a flat surface and the screen is tilted all the way back (which isn't very far).
The T300 Chi is a study in compromises Like so many other Windows 8.1 convertibles, the T300 is also rather awkward to use as a tablet. It's over one and a half pounds without the keyboard, and its large display combined with fat bezels make it much more clumsy to use than an iPad Air 2. The 12.5-inch, 16:9 screen works best in landscape mode, and while it has lots of resolution and wide viewing angles, there is uneven backlighting that's distracting and hard to ignore. Combined with the fact that Windows 8.1 is better suited for desktop environments than as a tablet interface, the T300 is best thought of as a laptop that can work as a tablet in a pinch, not the other way around.

The Core M processor in my review unit is clocked at 1.2GHz and combined with the 8GB of RAM on tap, has no trouble handling most basic computing tasks. It surely won't play any modern 3D games, but working in Chrome, Word, and other Windows 8.1 apps is no issue. I'm able to have as many tabs open in Chrome as I need without the system grinding to a halt, and switching between apps is quick and painless. I often forgot that I was using a computer that was more tablet than laptop, though the heat from the back of the T300 was enough to remind me that this is a full-blown Windows 8.1 machine and not a crippled charlatan faking the role.

The T300 has more heat and less battery life than the average tablet

In addition to the heat, the speed and power in the T300 Chi come with less battery life than you'd expect from a tablet or even a modern ultrabook. The T300 lasted for 6 hours and 38 minutes in our rundown test, and in normal usage of browsing the web in Chrome, chatting with coworkers in Slack, and typing in Microsoft Word, the battery would kick the bucket in about five hours. That's a lot less than the iPad Air 2 musters, and it's far behind what you can get with the Surface Pro 3, which might be the T300's closest analogue in terms of performance and design (if not price). The T300 could be the ultimate road warrior's computer, but its average battery life make it hard to go all day away from an outlet.

Many have looked at Apple's upcoming MacBook as the future of laptop computers, even if it's too forward-thinking for where we are today. The T300 Chi is very similar to the MacBook in many respects: it's incredibly thin, solidly built, and attractive to look at. It also comes with many of the same compromises as the MacBook, namely a lack of port options. But the T300 does things differently than the MacBook will, and its attempt to be both a laptop and tablet at the same time don't do it any favors.
I'd love to have a Windows ultrabook that's as thin and powerful as the T300, but doesn't pretend to be anything else. Give me a full laptop chassis in place of the detachable keyboard, longer battery life, and a slightly better display with the bezels of Dell's XPS 13 and I'd have a machine that I could easily use all day. The T300 is close, and as a taste of the future, it's pretty cool, but it's not quite there yet.

Facebook Invites App Devs to Join in Messenger Family Planning

By John P. Mello Jr.
03/27/15 12:39 PM PT

Facebook CEO Mark Zuckerberg this week told an audience at the F8 conference for Facebook developers that the company's future lies in its family of apps and in giving the network's members the ability to share what they want, where they want.

"We're building this family so we can offer unique, world-class experiences for all of the ways that people want to share," Zuckerberg told some 2,000 developers attending the forum in San Francisco.
That shift from a single service to a family of applications is a significant one, he added. "Moving from just being a single service to a family of world-class apps for helping people share in different ways is the biggest shift that we've made in our strategy of helping to connect people in many years."

New Platform

A key part of Facebook's future strategy will be its new Messenger Platform.
"As Messenger has grown, we think this service has the potential to help people express themselves in new ways, to connect hundreds of millions of new people, and to become a really important communication tool for the world," Zuckerberg said.
In the past, only Facebook could add new features to Messenger. That's changing with Messenger Platform, which allows developers to create apps that hook into Messenger, he explained.
In addition, the platform can be used by businesses to communicate directly with their customers through Messenger.
"Helping people communicate more naturally with businesses is going to improve, I think, almost every person's life," Zuckerberg said.
With Messenger Platform, it almost seems Facebook is creating another mobile operating system, noted Jan Dawson, chief analyst at Jackdaw Research.
"It's seems to be building an operating system on top of the existing operating systems," he told TechNewsWorld.
The platform will improve the workflow between apps by making it easier to share data among them. "Consumers will have a richer experience," Dawson said.

Competitive Pressure

Expanding Messenger's capabilities may be a market necessity.
"They had to do something to make Messenger more relevant compared to the other solutions out there that people have adopted and are more flexible," said Jim McGregor, founder and principal analyst with Tirias Research.
"They're trying to give Messenger all the features the other messenger apps have and doing more by reaching out to e-commerce. It's an aggressive goal -- especially when you're trying to pull e-commerce into it -- but Facebook is an aggressive company," he told TechNewsWorld.
"They're going to need a lot of support for this," he added, "because they're not just asking consumers to use this, but they want businesses to use it. That's a huge challenge."
Messaging is a popular worldwide phenomenon that Facebook wants to fully exploit.
"It's trying to make Messenger a more vital, broader tool," said Greg Sterling, vice president of strategy and insight for the Local Search Association.
Although Zuckerberg touted the "family of apps" approach as the best way to meet all Facebook followers' needs, it may be a way to cope with future uncertainties in the market.
"They're hedging, to some degree, for the future," Sterling told TechNewsWorld.
"These apps have different fan bases, so it's a diversification strategy," he explained. "If they absorbed the apps into the Facebook app, it would have destroyed a lot of their value."

Embedded Video

In addition to announcing Messenger Platform, Facebook unveiled new ways to embed video into outside websites. That's an especially attractive feature for professional publishers on Facebook.
"If you're a publisher and you've got great video on Facebook, you want the most distribution you can get," said Gareth Capon, CEO of Grabyo.
"As long as you're happy seeing that video shared everywhere, you'll be happy to embed that video on third-party sites where you can get additional consumption," he told TechNewsWorld. "The best part of embedded content is you still have control of it, so if you want to expire that content or remove it, you can do that through the Facebook platform."
Facebook also released a software development kit for its Parse platform for the Internet of Things.
With that step, Facebook is showing it's ready to compete with other big players, like Apple, Samsung and Google, who already are preparing for an explosion of IoT devices in the coming years.
