5 Operating Systems Making Big Waves This Week

Filed under
OS

It's been a busy week for operating systems (OSes). Here's a rundown of what happened and the implications.

1. QNX to Power BlackBerry Tablets

It's not often an embedded OS that controls Las Vegas hotel fountains, car audio units and air traffic control systems makes the news, and this time last week you'd have been hard pressed to find more than a handful of people who had ever heard of QNX.

That is until Research in Motion announced it will be basing its BlackBerry Tablet OS on QNX, which it acquired earlier this year (and promptly made closed source). QNX will thus be at the heart of the highly specced BlackBerry PlayBook tablet aimed at enterprise users when it is released in 2011.

The QNX OS is a far cry from anything RIM has used in its BlackBerry mobile devices before: It's a POSIX OS based on a microkernel architecture, with device drivers, networking stack and file system all running in memory-protected user space. It also features an adaptive partitioning scheduling system, which has an effect similar to Windows SQL Server 2008's Resource Governor: It aims to guarantee applications a set percentage of processor resources, ensuring real-time applications keep running even when the OS is doing a significant amount of multitasking.

2. Anti-malware to Be Built Into Windows?

Matching databases to Linux distros

Relational database management systems (RDBMSs) aren’t the sort of thing to get most folk out of bed in the morning – unless, of course, you happen to think they’re one of the most brilliant concepts ever dreamed up. These days you can’t sneeze without someone turning it into a table value in a database somewhere - and in combination with the freely available Linux operating system, there’s no end to them. Most Linux distros make it almost trivial to add popular DBMSs to your system, such as MySQL and MariaDB, by bundling them in for free in their online app stores. But how do you tell which combination - which Linux distro and which DBMS - will give you the best performance? This week we've revved up the Labs servers to ask the question: what level of performance do you get from OS repository-sourced DBMSs? Read more

The Curious Case of Raspberry Pi Consumerism

I find the attitude of many within the Raspberry Pi community to be strange and offensive. I first discovered this odd phenomenon (odd because it contradicts the ethos of the project's academic foundations) back when it first started, as many within the Raspberry Pi community took an extremely hostile attitude toward academic freedom, apparently in defence of various parties' highly dubious intellectual monopolies (Broadcom and MPEG-LA, for example). I pointed out the irony and hypocrisy of their attitude at the time, explaining that they were more than happy to leech Free (as in freedom) Software for their own benefit, but then balked at the prospect of freely sharing the results, and in particular this contradicted their stated academic goal of facilitating better computer education in UK schools, an environment that rightly demands open access to knowledge.

Google Chrome 38 Beta Brings New Guest Mode and Easier Incognito Mode Switching

The developers have explained that the user switching feature has been redesigned and it will make changing profiles and into the incognito mode a lot simple. They have also added a new experimental Guest mode, a new experimental UI for Chrome supervised users has been implemented, and numerous under-the-hood changes have been made for stability and performance. "This release adds support for the new element thanks to the hard work of community contributor Yoav Weiss, who was able to dedicate his time to implementing this feature in multiple rendering engines because of a successful crowd-funding campaign that raised more than 50% of its funding goal."
