Forward to the past with Windows update: review

 


NEW YORK: Even as Microsoft prepares for a future dominated by touch-screen devices, it is steering its Windows system to embrace more of the past.

The divide between old and new is less pronounced in the latest, free update. That's a welcome change, as that's one of the things that annoy me most about Windows 8.

As sales of smartphones and tablets grow rapidly, Microsoft reshaped Windows so that PCs came to look, work and feel more like mobile devices.

Windows 8 has a full-page, tablet-like start screen filled with large icons, or tiles. Traditional mouse and keyboard controls still work, but it's more efficient if you use touch-screen controls. Windows 8 has a desktop mode that resembles older versions of Windows, but it steers users toward the touch-centric tile mode.

Many people hated Windows 8 when it came out in October 2012.

Microsoft responded a year later with Windows 8.1. With the free update, people can change settings to boot computers directly into the desktop. Windows 8.1 restores a Start button on the lower left corner of the desktop, though without all the functionality found in older versions. Windows 8.1 also lets people add their favorite desktop apps to a horizontal taskbar at the bottom of the screen.

In short, Windows 8.1 doesn't try to force people into the tile screen as often.

Still, Windows 8.1 feels like two separate systems. Your favorite desktop apps are on the desktop's horizontal taskbar, while your favorite tile-mode apps are on the tile-based start screen. How you perform tasks such as closing an app depends on which mode you're in.

Last week's update, simply called Windows 8.1 Update, brings more consistency:

- The tile screen now has prominent buttons for key controls - namely search and shutting down. No longer do you have to figure out how to pull those options out like a sock drawer from the right side of the screen. Microsoft could have gone further by also including a button for settings, but I'm getting greedy.

- Closing apps in the tile mode used to require moving your cursor to the top, clicking the mouse or pressing the screen until the app shrinks and dragging all that to the bottom. Gone was the "x'' at the top right of all apps to close them.

That "x'' is back, along with a button to minimize, or hide, the app while leaving it running. Unlike past versions of Windows, these buttons at the top disappear until you move the cursor to the top. The good news is this works whether you're in desktop or tile mode, contributing to consistency.

- That desktop taskbar at the bottom now accepts your favorite tile-based apps as well. You're no longer left with some of your favorites in one place, and the rest in another. And the taskbar now appears when you're in tile mode, too, though it's hidden until you move the cursor to the bottom.

- By default, laptops and desktops boot to the desktop mode, without a setting change required on your part. Tablets still go to the tile-based start screen more fitting for tablets.

- Opening a photo, music or video file in the desktop no longer takes you to a tile-based app. You stay in the desktop and use desktop versions of the apps instead. And closing a tile-based app now brings you to the previously used app, not automatically to the tile-based start screen.

These tweaks, though small, are significant when considered on the whole. It's as though Microsoft is acknowledging that tablet-style controls aren't always best for PCs, especially those without touch screens.

In unveiling the update, Microsoft also hinted at a future that embraces even more of the past:

- Even with the update, you're restricted to two to four tile apps on the same screen. You can decide how much horizontal space each app takes, but you can't adjust the vertical space or have an app overlap over part of another.

Microsoft promises that in a future update, you'll be able to run tile apps as regular windows in the desktop mode. As long as you stay in the desktop, there would no longer be a distinction between the two types of apps.

- Clicking on that restored Start button in the desktop now takes you to the tile-based start screen. You can't open apps or access settings from that button, the way you could with previous versions of Windows. In a future update, you'll be able to do that.

Microsoft hasn't said when the next version will come out, but that preview and last week's update together show that Microsoft is listening to customers.

Many people have resisted buying a Windows computer because of the abrupt changes Windows 8 forces on users. The latest changes will give potential buyers fewer reasons to resist.

Samsung's Android 4.4 update reportedly puts an end to benchmark rigging



5292013115024PM_635_samsung_galaxy_s_4.png

Last July, Samsung was caught in a bit of controversy when its flagship smartphone of the time, the Galaxy S4, was seen optimising its behaviour to score higher in commonly-used benchmarking apps.
According to the findings, the Samsung Galaxy S4 would expose higher-speed cores to certain applications like GLBenchmark 2.5.1, AnTuTu, Linpack, and Quadrant apps, while the power available to other apps would be capped at a lower speed, in an attempt to increase the battery life of the phone. This meant that the CPU power available to your typical apps was lesser than what you would expect based on the benchmarks score. Samsung allegedly did this 'optimisation' for GPU speeds as well.
However, it seems this practise has been put to an end with Samsung's Android 4.4 update for the Galaxy S4. According to a report by Ars Technica:
Moving to Android 4.4, that strange CPU activity stops happening. Every single benchmark we ran prompted variable-but-normal fluctuations in CPU speed based on actual activity. Speeds would ramp up for a couple of seconds while the app launched, but once it became idle, the speeds settled back down to where they would normally be.
Compare this to the behaviour in Android 4.3 "where all four cores go right to the maximum speed of 1.9GHz when a benchmark app is opened."
So has Samsung just hidden the new set of optimisations deeper in the code, or given up on the practice? Seems like it's the latter.
John Poole of Primate Labs, the developers of popular benchmarking app Geekbench told Ars, "I'm inclined to think that the change between 4.2.2 and 4.4.2 is due to Samsung tweaking the overall power and performance settings rather than a new harder-to-detect boost."
Similar optimisations were also noted in the Galaxy Note 3, so it would be interesting to see if a software update makes an impact on the phablet's performance in benchmarks as well.
To be fair to Samsung, it's not the only manufacturer that has been caught optimising its hardware for benchmarks. Anandtech noted last year that almost all manufacturers indulge in the practice. However, it seems that like almost everything else that it does, Samsung is (or at least was) better than others in this department as well.
