SkyDrive in Windows 8.1: Cloud Storage the Way It’s Meant to Be

Peter Bright:

The files themselves use the reparse point mechanism first introduced in Windows 2000. During that first sync, stub files ("reparse points") are created to mimic the directory structure stored on SkyDrive. Any operation on these files is intercepted automatically, allowing SkyDrive to download the file on-demand.

The use of this (rather low-level) mechanism makes SkyDrive in Windows 8.1 very transparent. Virtually any application should work correctly, with only a download delay disclosing that a file isn’t stored locally.

As a result, you can have tens or hundreds of gigabytes of files stored on a server, while still retaining pseudo-instant access. There’s no long sync process.

Signed Mac Malware Using Right-to-Left Override Trick

F-Secure:

The objective here is not as convoluted as the one described in Kreb’s post. Here it’s simply to hide the real extension. The malware could have just used “Recent New.pdf.app”. However OS X has already considered this and displays the real extension as a precaution.

However, because of the RLO character, the usual file quarantine notification from OS X will be backwards just like the Krebs case.

AirPort Time Capsule 802.11ac

Michael Brown:

Based on my experience testing 802.11ac routers with Windows machines, I expected the 802.11ac Time Capsule to be considerably faster than the 802.11n model. And that’s certainly what my WiFiPerf results indicate. But these real-world file transfers defy that expectation.

The current theory, first published at Anandtech, is that OS X is not properly scaling TCP window size during file transfers to allow the MacBook Air’s 802.11ac client adapter to achieve peak performance. While Apple has not confirmed this to be the problem, the company is aware of the performance discrepancy and is reportedly working on a solution.

Apple has also integrated the power brick into the device and added “AirPort” to the product’s name.

Apple’s Answer on Upgrade Pricing

David Smith:

Logic Pro X is a Major (with a capital M) update to their professional audio editing suite. It appears to represent a significant investment in both time and resources. So how is it being sold, especially to people who already paid $200 for the previous version (Logic Pro 9)? It is a separate app download with a full cost purchase. No upgrades, no introductory pricing, just straight forward sale.

Update (2013-07-18): Also revealing is that Logic Pro X is not sandboxed.
