Keeping systems patched is one of the most basic security protections available. However, ongoing scanning of web hosts in Australia and New Zealand suggests that many servers are not being regularly updated or using basic security mechanisms.


Issues When Running Databases In The Cloud

Databases underlie most other applications, so it’s no surprise that database-as-a-service options are becoming more common. But if you’re thinking of rolling out databases in a cloud environment or consuming them as a service, there are some important caveats to bear in mind.


The Tech Wisdom Of Sir Tim Berners-Lee

Having already spoken at several locations around the country during his Australian tour, Sir Tim Berners-Lee gave the final keynote at Linux.conf.au this morning. What are his thoughts on open platforms, operating systems choice, HTML5 DRM and the <blink> tag?

Why Hasn't Everyone Moved To IPv6?

We’ve known for decades that the available pool of IPv4 address was eventually going to dry up, but despite numerous warnings usage of its successor IPv6 is still minimal. Why haven’t we migrated yet? Geoff Huston, chief scientist for regional internet registry APNIC, suggests that the answer is that carriers are too cheap to make the switch and are happy to rely on network address translation (NAT) systems instead.


Did The Optus-NRL Legal Case Ruin The Cloud For Everyone?

Last year’s court decision that ruled Optus’ TV Now catchup service effectively illegal clearly dealt a blow to any plans to develop similar cloud-based TV recording services. But did it also cast a broader shadow over the prospects for other cloud-based developers?


Why Absolute Technology Rules Can Be Bad For Your IT Career

Technology inspires enthusiasm and passion, and we often defend our choices in semi-rational tones replete with religious fervour. In your own life, you can do what you like. When you’re working with IT in your career, you need to learn to compromise more readily.


How To Be A Better Systems Administrator

In the cloud computing era, effectively managing servers and systems is more important than ever. Follow these basic principles to ensure that your workplace systems run smoothly (and advance your own career in the process).
