Remote access with Guacamole

Many of us, who work in the technology industry, find it beneficial to have somewhere to learn and test new technologies. While providers such as Amazon, Rackspace and Digital Ocean etc, are enough for most Developers, we Sysadmins often need something more. Labs This means we end up creating our own Labs. For many these are hosted at home, and some host at external companies. Once we have setup our environment (probably a one to three hypervisors and many VMs and containers) the problem of remote access comes up. [Read More]

Dropbox and SELinux

OK, so Dropbox isnt 100% Open Source but Im a pragmatic kinda guy and I do love Dropbox. However it (Dropbox) doent seem to like SELinux it seems. I know its so tempting to reach for the “turn off SELinux” switch but wait, its actually very simple to make SELinux allow Dropbox to work. It turns out that Dropbox tries to do some naughty stuff that SELinux is there to protect us from – namely executing out of the memory buffer. [Read More]

Operating System Choice for Critical Systems

It NEVER ceases to amaze me that when selecting an operating system for a critically important role, that people still chose Windows. Now this isnt a rant about how Linux or BSD are better or more secure than Microsoft Windows. I mean I think its quite an easy argument but one thing that is not up for debate is that Microsoft Windows is the most targeted operating system when it comes to Malware. [Read More]

FOSDEM 2010

We I have just returned from my anual trip to FOSDEM, held in Brussels. FOSDEM is one of my favourite conferences, there are so many interesting tracks and the, already large, conference seems to grow bigger each year. FOSDEM is entirely free and exists on a combination of donations and sponsorship, a model which clearly seems to work. Like all good conferences you are inevitably faced with with the problem that there are multiple talks that you would like to see but the are being held at the same time. [Read More]

WordPress comes to Android

For a while now I have been quite jealous of the SquareSpace iPhone app that let’s you manage you site right from your smart phone. Well now, if you have a WordPress blog and an Android phone you too can have this functionality. WordPress is now in the Android app store, and what’s more its totally free. Thanks to readwriteweb for the headsup. Note: This post was done from my phone, alhtough the above link was impossible to do and categories also seem to be broken at the moment but this is a 1.

Give Google a Break

Google are developing a new operating system, aimed squarely at the netbook market. The ethos behind it, like with most things at Google in the last 12 months, is speed – they want it to take no more than 7 seconds to boot. Once logged in you will only have access to a web browser – the browser will be Googles Chrome Browser, as you may expect. There will be no desktop or other apps, everything will be done from the browser. [Read More]
