Submission + - Windows 8 has scaling issues on high-PPI displays (techreport.com)

crookedvulture writes: "High-PPI displays are becoming increasingly popular on tablets and notebooks, but Windows 8 may not be ready for them. On a 13" notebook display with a 1080p resolution, the RTM version of Win8 scales up some desktop UI elements nicely. However, there are serious issues with Metro, which produces tiles and text that are either too small or too large depending on the PPI setting used. That setting, by the way, is a simple on/off switch that tells the OS to "make everything bigger." Web browsing is particularly problematic, with Internet Explorer 10 introducing ugly rendering artifacts when scaling pages in both Metro and desktop modes. Clearly, there's work to be done on the OS side to properly support higher pixel densities."

Submission + - Promoting Arithmetic and Algebra by Example

Capt.Albatross writes: A couple of months ago, the New York Times published political scientist Andrew Hacker's opinion that teaching algebra is harmful. Today, it has followed up with an article that is clearly intended to indicate the usefulness of basic mathematics by suggesting useful exercises in a variety of 'real-world' topics. While the starter questions in each topic involve formula evaluation rather than symbolic manipulation, the follow-up questions invite readers to delve more deeply.

The value of mathematics education has been a recurring issue in Slashdot.
