We have to break this array down to split the selections for our data processing needs, or you can choose to save the serialized complete array into one MySQL database field.
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.
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

(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.
Microsoft has announced through their Lumia Facebook page that the global rollout of Windows 10 Mobile will begin this December, bringing the company's completely revamped mobile operating system to older Windows Phones before the end of the year.
The statement from a Microsoft representative on Windows 10 Mobile upgrades is as follows:
Windows 10 is available on PCs and tablets now, and while Lumia 950 and Lumia 950 XL ship with Windows 10 for phones, broad availability of Windows 10 on other devices, including mobile phones, will begin rolling out in December.

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.
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.

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.
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.
