Windows 8.1 fixes problems, adds new features, but touch screen is still the focus (hands-on)

Today, during the keynote for the Microsoft Build conference in San Francisco, the company announced the preview version for Windows 8.1 (download the preview here). As a point upgrade to Windows 8, there are few sweeping changes to the operating system, but Microsoft has thankfully made some tweaks to the interface, along with upgraded apps and other enhancements that users will appreciate. But it's important to note that if you were hoping for a return to a Windows 7 layout, you're going to be disappointed; Microsoft is sticking to its guns on the Modern UI (the tiled Start screen interface), and you'll still be using it as your main launching point. With that said, Microsoft has added a few features that make it a bit more palatable to keyboard-and-mouse Windows desktop users.

In developing Windows 8.1, Microsoft says it listened to feedback from users and tried to solve the problems people were having with the new interface. In our time with the updated OS, we think the company has done a good job on a lot of fronts and has added a lot more to like, but we suspect that some people will still find the OS' reliance on touch off-putting.
The Start menu returns! (sort of)
One of the biggest complaints for Windows 8 was the removal of the Start (or Windows) button in the lower-left corner of the desktop. Microsoft's move toward touch-screen computing made it rethink the way people use their computers in Windows 8, but those who spent years clicking the Start button to navigate the OS weren't pleased with an entirely new way of doing things.

As a compromise of sorts, Microsoft has reintroduced the Start button in Windows 8.1 in the lower-left corner of the screen. Clicking on it brings up the Start screen, where you can type a few letters to find and open apps, just like in Windows 8. While you still don't get the exact same pop-up menu you had in Windows 7, Microsoft has added the ability to right-click the new Start button to get to common Control Panel settings, open the Task Manager, perform a search, and other useful system tools. At the bottom of the pop-up menu you have the option to shut down or restart your computer -- a function that was previously found in Windows 8 by mousing to the top-right corner of the screen, dragging downward, clicking Settings, clicking Power, then clicking Shutdown or Restart.
There's obviously nothing groundbreaking about bringing a widely used interface element back from a previous OS, but we had hoped Microsoft could bring it back completely. We use Windows 8 every day, but we still miss the convenience of having recent files, the Control Panel, and everything else from Windows 7 in one spot, whereas you now need to drill down in multiple different areas when using Windows 8. Nevertheless, we're glad the company has made the menu more easily accessible for mouse-and-keyboard users at the very least.
Boot to Desktop
A change that many users will appreciate is the capability to set up the Windows machine to boot directly to the desktop from within the OS. It seems that Microsoft has heard the outcry from users, or perhaps the company is finally admitting to some extent that the tiled Modern UI is not necessarily ideal for mouse-and-keyboard setups. In any case, we're happy it's been added.

Xbox Music gets much more intuitive
In Windows 8, Xbox Music allowed you to stream free music from a huge library of more than 30 million songs. In Windows 8.1, the app has been redesigned to make it easier to move around the interface. A left navigation pane lets you start a radio station, explore artists, play songs from your collection, or create and manage playlists. On the right side of the screen you can view artists, explore content, watch videos, and more. We noticed this is a theme in Windows 8.1: many of the interface elements include a left-side nav with content on the right, and we think it's much better than the sideways scrolling found in earlier versions of Xbox Music. You can create Pandora-like radio stations by entering an artist to get a stream of similar music, and you can create playlists of music you choose. The process is a little involved, but when you're finished you can listen to a custom playlist in exactly the order you want. There are obviously other services like Spotify that let you choose songs to play, and Pandora, which does free streaming, but the new layout in Windows 8.1 makes it much easier to use and might be your new go-to app instead of third-party options.
The Search charm produces better results from several different sources.

Search gets an upgrade
The search charm in Windows 8.1 does a little more than it did before. Now when you perform a search, you'll get global results from several sources including files, SkyDrive, apps, and the Web. All your search results are displayed horizontally, with more results from other sources when you scroll to the right.
When you search for popular actors, musicians, sports figures, and other well-known people, Windows 8 displays what it calls a Hero screen. On a search for Kanye West, for example, you get a large photo, related songs and videos, movies, and -- as you scroll further -- more-basic Web search results to Web sites and images. When a person isn't as famous, you get standard Web search results with links to Web sites and photos.
More flexibility with Snap views
In Windows 8.1 you'll now be able to run more apps simultaneously on one monitor by resizing app windows and using the Snap function. Now, you can have up to four running apps on one screen simultaneously, as long as your screen has a high enough resolution: 2,560x1,440 pixels is required to display four simultaneous apps. With a dual-monitor setup, you could have eight apps running at once. On the Surface Pro that Microsoft loaned us for testing, we were only able to get three apps on one screen (Surface Pro features a 1,920x1,080 resolution), but it was easy to see how it could be useful.
Personalization
Microsoft has added some personalization features with both the Start screen and lock screens so people can add a bit of their own style to desktops and tablets. There are more colors to choose from for backgrounds, and you can display a slideshow on your lock screen with photos currently on your hard drive or from those stored on SkyDrive.
The new camera app has a ton more useful features, including editing tools, color enhancement, and filters.

Much-improved camera app
The camera app has been improved significantly in Windows 8.1. In Windows 8 your only option was to crop photos, but in 8.1, you get a full set of photo-editing tools to enhance color, adjust brightness and contrast, and red-eye, and pick from six different filters.
Our favorite part of the app is the color enhancement tool, which lets you pick a color on the photo, and enhance just that color to make it stand out. Where the camera app was almost useless before, in Windows 8.1 people will be more likely to use it with all the new features.
The new Windows Store has a cleaner layout with bigger images.

Windows Store
Part of this week's Microsoft Build event is about getting developers excited about making new apps for the Windows Store. A redesign in Windows 8.1 might be a step in the right direction with a cleaner look, larger images, and an overall more refined and sophisticated layout. Microsoft also made it so your current apps are now auto-updated, ensuring that you'll always have the latest versions.
One of the complaints of the Windows Store was that it didn't have a robust catalog of apps. While it's slowly grown since Windows 8 first arrived, hopefully a new look and auto-updates will make developers take a new interest in it.
Do the changes make Windows 8 better?
The short answer appears to be: yes. Windows 8.1 streamlines much of the touch interface, while adding many cosmetic and tangible, utilitarian features.
We think the real question, however, is: does 8.1 do enough to sweeten the bad taste left in the mouths of many Windows 8 users? That’s a much more difficult question to answer and one that will require much more time spent with the new OS.
Windows 8.1 probably still relies a bit too much on touch and may not do all it needs to repair damage caused by its predecessor; however, it’s a much-needed and in some cases impressive step in the right direction.

iOS 7 beta 2 arrives with bug fixes, iPad version



Apple on Monday released the second beta of iOS 7, exactly two weeks after the first iteration of the software was doled out to developers.
The new version promises only to fix bugs and contains other undocumented "improvements."
But the big new thing in this release is a version of the software for iPads -- both the regular and Mini models. The first version of the software only came for iPhones and iPod Touches, with Apple promising to add support for other devices as time went on.
The software requires developers to sign a privacy agreement, but that hasn't stopped numerous developers and some blogs from posting extensive hands-on previews of the new OS.
It's been standard practice for Apple to roll out several beta versions of the software before it's released to the public, which Apple has said will happen in the fall. In terms of how many more of these to expect, iOS 6 had four different beta versions between its June debut and late September release last year.
Perhaps not since 2010's iOS 4 (which brought multitasking) has there been quite so much scrutiny on just what Apple's up to with these interim updates. iOS 7 is a massive visual and, in some cases, functional overhaul of the versions that came before it, and many things are expected to change before it's officially released.

Microsoft offers hefty bounties to thwart hackers

BOSTON (Reuters) - Microsoft Corp is looking to recruit computer geeks in its ongoing efforts to protect Windows PCs from attacks, offering rewards of as much as $150,000 to anybody who helps identify and fix major security holes in its software.
Microsoft unveiled the rewards program, one of the most generous in the high-tech industry to date, on Wednesday as it sought ways to prevent sophisticated attackers from subverting new security technologies it has introduced in the latest versions of the Windows operating system.
The program is open to computer experts as young as 14, though minors need permission from their parents. Residents of countries under U.S. sanctions, such as Cuba, Iran, North Korea, Sudan and Syria, are banned from the program.
The sheer size of the bonus is likely to grab the attention of the hacking community, though claiming the big money will require them to do battle with Microsoft's latest anti-hacking technology and then detail their approach.
"It's pretty generous, though what they are asking for is a pretty high bar," said Chris Wysopal, chief technology officer of Veracode, a security firm that helps identify software bugs.
Microsoft has plenty of competition in getting elite hackers to turn their attention on its aging Windows franchise, which operates the vast majority of the world's personal computers.
Windows computers have been involved in most major attacks to date, including the recent Citadel cyber crime ring that stole more than $500 million from banks and the Stuxnet virus that attacked Iran's nuclear program in 2010 by exploiting previously unknown bugs in Microsoft software.
COMPETING FOR TALENT
The best hackers are heavily recruited by the military, intelligence agencies and big corporations, who lure them with scholarships and high-paying jobs.
Microsoft is also competing for the attention of the top hacking talent on a growing global gray market, where information about vulnerabilities is sold to criminals as well as governments that use it in military and intelligence operations. Bounties start at $50,000 for tools that enable attackers to break into computers, even when they are protected by up-to-date security software.
In the industry, exploits of such vulnerabilities are called "zero-days," because a targeted software maker has had zero days' notice to fix the hole when the malicious software is eventually discovered. (See SPECIAL REPORT: http://link.reuters.
Mike Reavey, senior director with the Microsoft Security Response Center, declined in an interview to talk about the "zero day" market for vulnerabilities in Windows products, saying the company was seeking to encourage hackers to use their skills in helpful ways.
"It's difficult to comment on the dark side," he said. "The intention of these (bounty) programs is to incentivize good behavior."
Reavey said he hoped Microsoft's new program would woo some candidates away from an annual contest known as Pwn2Own (pronounced "pown to own"), which has become a key venue for elite hackers to disclose major security flaws in software.
The latest Pwn2Own, which was held in Vancouver in March and sponsored by Hewlett-Packard Co, paid out nearly $480,000 in prize money, according to HP's website.
Hackers won the competition by identifying new ways to "pwn," or take ownership of, browsers from Microsoft, Firefox and Google Inc, Oracle Corp's Java and Adobe System Inc's Flash and Reader software.
Some other big technology firms already offer similar programs. Google has handed out $1.7 million in 3 years, including prizes as big as $60,000. Facebook Inc said it has paid out $500,000 to $1 million since it began its program two years ago. Adobe does not offer bounties, though it brings in hackers as temporary consultants to help fix problems that they identify.
Microsoft is also running a one-month contest, starting July 26, offering bounties of up to $11,000 to hackers who find bugs in the trial version of its new Internet Explorer 11 browser, which will be in preview release.

IBM packs 128TB of flash into brain-simulating supercomputer

Drawing from engineering ideas that are revamping personal computers, IBM and two Swiss universities are using flash memory to improve performance of a supercomputer designed to simulate an actual mouse brain.
But there's a lot more flash memory than you'll find in the latest laptop.
A PC's solid-state drive may come with something like 128GB to 512GB of flash memory. The mouse-brain project's specially upgraded version of a Blue Gene/Q supercomputer has 250 to 1,000 times as much flash memory -- 128 terabytes.
IBM announced the development in conjunction with the International Supercomputing Conference 2013 that takes place next week in Leipzig, Germany. Felix Schürmann, general manager of the Blue Brain Project, is scheduled to present resultsat the show.The supercomputer project, in conjunction with the Ecole Polytechnique Federale de Lausanne (EPFL) and the Eidgenoessische Technische Hochschule Zurich (ETH Zurich), aims to model the 70 million or so neurons that make up a mouse brain. The work dovetails with the Blue Brain project and the European Union's Human Brain Project.
Flash memory is cheaper, more capacious, and slower than DRAM, the type of memory used to store data that a computer processor needs pronto. Flash memory also is faster but more expensive than hard-drive storage. For that reason, it often occupies an intermediate tier between hard drives and DRAM (dynamic random access memory) in the memory hierarchy.
"The major reasons are both cost and speed," said IBM Research computational scientist Alessandro Curioni of the decision to use flash memory. "Detailed brain simulations in particular have unique requirements that make it desirable to use a different ratio of compute [power] to memory [capacity] than today's systems."
The flash memory will store a variety of data, including data from the mouse brain that's under study, simulation results that are awaiting further analysis, and checkpoint data to keep track of what's going on in the simulation, Curioni said.
Flash memory in PCs today is usually connected with the SATA interface used to hook up hard drives, but the Apple's new Mac Pro puts flash memory a step closer to the processor by linking it with the PCI Express interface. IBM wouldn't say how it's hooking up its flash memory, citing "patent discussions," but said it is "deeply embedded."
Computer scientists have long looked at brains for inspiration, and in recent decades, one avenue has been in self-learning neural networks that behave in some ways like a brain's teeming interconnected neurons. The Blue Brain project, though, isn't a neural network. Instead, it seeks to simulate the physical reality of real nerve cells, including their shape, size, and electrical behavior, IBM said.
