Microsoft showed the new Visual Studio 2013 at its Build developer conference today. The new independent development environment (IDE) features include performance tools for power consumption, asynchronous calls for debugging and an overall focus on the connected app.
The new tools in Visual Studio, now available for download, are meant to appeal to mobile developers.
The PostgreSQL 9.2 release is available. "Since the beta release was announced in May, developers and vendors have praised it as a leap forward in performance, scalability and flexibility. Users are expected to switch to this version in record numbers." LWN ran a detailed look at this release in May.
KDE have released version 4.8 of their free and open source software bundle. It provides many new features, improved stability and increased performance. Highlights for Plasma Workspaces include window manager optimizations, and the redesign of power management.
PostgreSQL is one of the most versatile, powerful and reliable object-relational database systems available. The enterprise-class open source database is in use by some of the largest companies in the world, handling exceptionally large workloads. But you knew all of that already, so let's talk about a few features in PostgreSQL you probably didn't know about already.
Phoronix: Linux 3.13 Kernel Power Consumption Benchmarks
With word recently of a 50 Watt Linux kernel power regression that's still being investigated, I carried out some more power consumption tests of a Core i7 4770K Haswell system to see if its power usage has been impacted by recent kernel upgrades...
I'm creating a "keyless" entry system using an nRF24L01+ and an AVR on both sides.
The base units power consumption isn't a concern, however the keys power consumption is.
The key will be powered by a CR2032 battery, and I would like to have an average consumption <14 µA.
I've played around with duty cycles, but I can't get the consumption low enough since every message takes abo
