Reference: Android 5.0 Full Disk Encryption

Encryption and Storage Performance in Android 5.0 Lollipop

As you can see, there’s a very significant performance penalty that comes with enabling FDE, with a 62.9% drop in random read performance, a 50.5% drop in random write performance, and a staggering 80.7% drop in sequential read performance. This has serious negative implications for device performance in any situation where applications are reading or writing to disk. Google’s move to enable FDE by default also may not be very helpful with real world security without a change in user behaviour, as much of the security comes from the use of a passcode. This poses a problem, because the users that don’t use a passcode doesn’t really benefit from FDE, but they’re still subject to the penalties.

I understand the need for FDE. But perhaps there needs to be user-selectable options as to what requires encryption.

Intel’s Ambition To Oust ARM In China

An article at 1Pad [Google Translate].

An article at PadNews [Google Translate].

If Intel can deliver the kind of performance shown with the Dell Venue 8 7000 to every partner at an economical price, they could have a real shot at it.

The problem, at least in China, is that their partners have a tendency to churn out device after device with no thought of future support. Those aren’t exactly great advertisements for “Intel Inside.”

A huge sea change would occur if Xiaomi were to use one of Intel’s designs in a new phone. But Xiaomi seems to want to do its own thing, chip-wise.

Whoa [Google Translate]:

If the budget is less than a thousand dollars, in fact, there are many big-name tablet to choose from, such as Asus, Acer, Dell, HP, and Huawei, the difference between these brands and some domestic brands may not be apparent in the short term, but after After several months of use, the gap between the two immediately apparent, the domestic flat all kinds of strange problems will ensue, but the most prominent problem with the battery, so you have plans to buy a domestic low-cost tablet PC, You have to be prepared to handle the psychological preparation of various incurable diseases.

Boldfaced emphasis added by me.

So, who should I believe?

Those who have bought from China and have had OK experiences?

Or those who report on China tablets, inside China, and have experience with many more of them?

Men Are Bluetooth, Women Are WiFi

I swiped this from Weibo:

BluetoothMenWiFiWomen

Men are like Bluetooth. As long as he’s next to you, he stays connected. But as you move away, he searches for others to connect to.

Women are like WiFi. They can see everything they can connect to but choose the best.

China eBook Software

PCPop has an article with “recommended” (most popular?) eBook reading apps [Google Translate].

PCPopWatercress01

Support for Web, iPad, Android, Kindle, and other platforms.

I’m intrigued by the claim that Watercress can do Kindle format eBooks. Do they really mean DRM-free MobiPocket?
