Windows Store Apps Security?

On a The Tablet Show podcast somebody mentioned that Windows Store apps on Windows 8 / RT are not completely protected, and it is possible to access and hack app's files. That is not surprising since after all they are just files (if they are just files, and apparently they are), and the user is (can be) admin.

A quick search finds the details...

Why is this a problem?
Because it is easy to turn a trail to a full app, or to remove adds, or to hack apps.
NEVER save any server access code or password to an app, in particular not well encrypted.
This similar to "rooting" a mobile phone or a tablet.

Let's hope that Microsoft will do a better job protecting the apps on Windows 8.1. Keeping "mobile" OS separate from "desktop" would be better. If Microsoft has created WinRT as a virtual machine on "Windows 8 Desktop", upgrade from Windows 7 would be trivial decision (no big changes), and all "goodness" of WinRT Apps would still be there on every desktop... Anyway...

There is a reason why iOS is separate from OS X...

Windows Store App making $30,000 a Month

There are iOS apps that are making $ millions.
Likely there are some such Androids apps, too.
Windows (8/RT) Store apps are still catching up,
but there are some some success stories like this:

Since this app was making money on adds, and there are rumors of add rates going down, it is not clear how long this would last...

WebP: A new image format for the Web

WebP — Google Developers

"WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller in size compared to JPEG images at equivalent SSIM index. WebP supports lossless transparency (also known as alpha channel) with just 22% additional bytes. Transparency is also supported with lossy compression and typically provides 3x smaller file sizes compared to PNG when lossy compression is acceptable for the red/green/blue color channels."

WebP (pronounced "weppy") is developed and used by Google on a large scale. So it must be good :)

SSD without enclosure

SSD is not a "disk", it is a memory, but for compatibility it was so far "packaged" into standard 2.5" HD enclosures with SATA connector. Now, there is SSD that is much smaller (1/8 of the size), with mSATA connector.

The primary purpose is for untrathin laptops (ultrabooks), and mini-PCs

price: $60 / 32 GB, $80 / 64 GB, $120 / 128 GB, $200 / 256 GB. Crucial m4 128GB mSATA Internal Solid State Drive CT128M4SSD3: Computers & Accessories
