Google makes changes to their search algorithm an average of once every 17.5 hours

With several hundred signals that are read and processed by their
search algorithm, we've always known that Google puts a tremendous
amount of time, money, and effort into making their results match
their users' needs. Now, we have an idea of how much tweaking is done:
a lot.

Their "search scientists" test the changes they make in a sandbox
environment to see how each change, twist, addition, and omission
reacts to various searches and search types.

"Just last year we launched over 500 changes to our algorithm so by
some count we change our algorithm almost every day, almost twice
over," said Google Fellow Amit Singhal.

Many of these changes happen simultaneously, so some days may have no
changes, but if you average out 500 changes over a year, that's about
1 change every 17.5 hours.

"There are almost always a set of motivating searches and these
searches are not performing as well as we'd like," said Engineering
Director Scott Huffman. "Ranking engineers then come up with a
hypothesis about what signal, what data could we integrate into our
algorithm."

We often take for granted how search engines come up with their
results, but this video helps to break it down for us in layman's
terms.

Windows 8 to offer easier file management

Ever find it frustrating trying to copy or move files in Windows? Then
some long-overdue improvements in Windows 8 should be welcome news.

Admitting that file management or the "copy jobs" feature now in
Windows can be confusing, Alex Simons, a program management director
on Microsoft's Windows engineering team, yesterday revealed four
enhancements destined to surface in Windows 8.

Contributing to the latest installment of Microsoft's ongoing
"Building Windows 8" blog, Simons said that copying, moving, renaming,
and deleting files are the most heavily used features in Windows
Explorer, accounting for 50 percent of all file management tasks.

But studies done by Microsoft confirmed that parts of the Windows 7
copy experience can be "cluttered and confusing." This is especially
true if you're are copying or moving files and folders with the same
names or copying or moving multiple files one after the other.

To offer a more user-friendly file management experience in Windows 8,
Microsoft came up with three goals: 1) create a single place to manage
and monitor all files being copied; 2) remove distractions and give
people just the information they need; and 3) put people in more
control of their copy operations.

As as result, Windows 8 users will see four new features in the
upcoming operating system designed to simplify the chore of copying
and moving files.

First, in past versions of Windows, a separate progress dialog box
would pop up for each new file that you were copying or moving. This
could sometimes result in dozens of different file copy boxes floating
around the screen. Windows 8 consolidates the process into one dialog
box for all files being copied or moved where you can more easily view
and control each individual file.

Top 10 Largest File-Sharing Sites

BitTorrent is no longer the dominant player when it comes to
file-sharing on the Internet. The five largest English language
websites dedicated to swapping files are all related to centralized
file-hosting services, also known as cyberlockers. The Pirate Bay and
Torrentz are the only BitTorrent sites that managed to secure a spot
in the top 10.

The Internet is the largest copying machine ever invented, and if we
take a look at the massive amounts of traffic file-sharing sites get,
millions of people are using it to its full extent.

4shared, the largest English language file-sharing site, is serving
2.5 billion pageviews alone every month, and this number is increasing
rapidly.

Below we have compiled a list of the top 10 largest (general purpose)
file-sharing sites on the Internet, based on measurements by Google.
What stands out immediately is that 8 of the 10 sites are related to
cyberlockers, and only 2 are BitTorrent sites.

This picture is quite different from the landscape 5 years ago when
BitTorrent sites dominated the file-sharing space. Early 2007 Mininova
was the first BitTorrent site to earn a place among the top 100
most-visited sites on the Internet, and soon thereafter they were
joined by The Pirate Bay.

In the years that followed BitTorrent sites continued to dominate, but
in the background cyberlockers were catching up, and catching up fast.
Where most BitTorrent sites were seeing moderate growth, several new
cyberlockers saw their traffic surge. In the last year many
cyberlocker sites have outgrown The Pirate Bay, Torrentz, isoHunt and
other popular torrent sites.

Below is the full list of sites based on Google's ranking. We have to
note though that several site owners in this list told TorrentFreak
that the monthly pageviews and unique visitors are hugely
underestimated. The Pirate Bay for example claims 1,500,000,000
pageviews, which is more than double the Google estimate. Other sites
report similar 'downgrades,' so overall the ranking would still hold.

iPhone hacker Comex says he's landed an internship ... at Apple

(CNN) -- A 19-year-old who is probably the world's most noted iPhone
hacker said Thursday he's been hired by Apple, the very company whose
products he's been hacking into.

"It's been really, really fun, but it's also been a while and I've
been getting bored," Nicholas Allegra, who's better known by his
pseudonym Comex, posted on Twitter. "So, the week after next I will be
starting an internship with Apple."

Apple did not immediately respond to a CNN request for comment on
Comex's internship at the company.

Forbes writer Andy Greenberg revealed Comex's identity this month,
calling him the "iPhone uber-hacker who keeps outsmarting Apple."

In the story, he noted that Comex was looking for an internship, and
he suggested that Apple give him one.

"Now it has," he wrote Friday.

Comex started the website jailbreakme, which lets iPhone users
jailbreak their phones simply by visiting that site. A jailbroken
iPhone can run apps that are not approved by Apple for sale in its App
Store.

The phones also can then be "unlocked," which makes it possible to use
them on wireless networks that Apple hasn't approved. International
travelers like that feature.

Other Apple hackers have praised the site as being incredibly
sophisticated. Dino Dai Zovi told Forbes that Comex's work is as
impressive as Stuxnet, a computer worm that apparently targeted Iran's
nuclear facilities last year.

It's fairly common -- more so than you might expect, at least -- for
big tech companies to hire once-nefarious hackers. These coding gurus
are sometimes better versed in the security vulnerabilities of a
company's products than anyone else in the industry.

And, these companies hope, the former hackers could use these skills
to make their products safer.

The blog MacRumors says Apple has made similar hires in the past:

"Earlier this year MobileNotifier developer Peter Hajas was picked up
as an Apple summer intern."

VentureBeat, however, says that's a new phenomenon for the world's
largest tech company:

"Hiring hackers isn't new in the tech world, but it's a fairly recent
development for Apple, which has usually tried to squash hackers by
more traditional means."

Greenberg, at Forbes, says these hires don't always go well:

"George Hotz, one of the first iPhone hackers, was sued by Sony after
reverse engineering the PlayStation 3, a move that set off a wave of
user anger at the company, resulting in more than 20 retaliatory
hacking attacks by the hacker collective Anonymous and others."

But he argues the Comex hire may be good for Apple:

"Apple, by taking the carrot instead of stick approach, has saved
itself that massive PR headache. And by hiring someone who actually
understands its products' security weaknesses, it may just be making
its users safer, too."
