I've been playing Half-Life recently, something to which I've looked forward for quite some time. I did get it playing under Wine years ago, but I thought I only got a little ways. I'm stuck In the Rails right now, but I remember this level.

Getting Squid3 on Debian 6.x to work with Active Directory, Security Groups and Websense

Filed under
Linux

I’ve had a need to get a local squid proxy to perform local filtering based on AD Security groups because it’s not something websense can do. I found this wonderful howtofoge guide online and Used it to setup the base system. This howto is a work in progress as the next stage is to get it working with DansGuardian or SquidGuard.

Prerequisites
Client Internet Explorer Browsers need to have “Enable Integrated Windows Authentication” ticked in Internet Options :: Advanced settings as well as Proxy Auto detection enabled – google these if not sure. All modern web browsers will support proxy auto detection. Firefox and Chrome also support Windows Authentication.

Enabling Dual Factor Authentication on Linux SSH logins..

Filed under
Linux

A couple of weeks ago I wrote a post on using a Chromebook to develop on a cloud platform. Its based on a Digital Ocean remote server and like most people who wish to attach to the command line interface on a remote server I use SSH. It’s an encrypted connection over the network/internet from end to end. However being a cloud server I was wondering if it was possible to secure this a little bit more?

A chat with a friend on the way into work provided me with a solution.

The solution is Two Factor authentication a system beased on a simple premise, something you know (the SSH password in this case) and something you have (your mobile phone in this case, but it could be a secure token) which will deliver a random number.

Using a Chromebook to develop in the cloud…

Filed under
Linux

Being a few months in with my Acer C7 Chromebook as my only laptop i’ve very pleased with what it does, I do have the Crouton Ubuntu chroot installed and upgraded the device to 16Gb of Ram, however there is one core thing I miss with this setup. VMWare/Virtualbox. I find i’m often building virtual machines, usually Ubuntu to test bsh scripts or build LAMP Environments to test some PHP out with. That isn’t something i’m able to do even on the CHROOT Ubuntu environment.

All however is not lost, and i’ve found a way to get round this..

They say a week in politics is a long time, well a year in the mobile phone industry is an eternity and what huge changes the industry is going through. A year ago the roost was ruled by Apple and Google, 3G was the fastest we can go and handsets were finding a stock size at 4.5″.. The world however of the mobile device is now a very different place and very much in a positive state of change..

Casual Programming and Linux Screen-Recorders

Filed under
Linux

After being retired (for four years) from teaching high school Computer Science, I decided to get back into programming again. I once taught a beginning programming class using the Ruby language, and I thought that would be a good way to get back into programming. So, I decided I needed a “Ruby refresher”, and I wanted to learn more about that language than I taught in the classroom.

Optimize your Linux rig for top-notch writing

I'm a big fan of Scott Nesbitt's writing, which has a technological bent, but is usually more about working effectively, rather than how tools can make you effective, which is a key distinction. Scott's setup reflects his focus on production rather than tweaking. He has his work tools and everything else is pretty much white noise—which is why LXDE/Lubuntu probably makes a lot of sense for his workflow. It's simple and it stays out of his way. Scott also gets bonus points for moving his family to Linux. That's a tough move, but given that his wife stole his ZaReason laptop, the conversion seems to have taken. Read more

IBM meets demand for Linux with training resources

IBM HAS REAFFIRMED its commitment to Linux with the announcement of an extension to Power Systems Linux. Following on from the company's $1bn financial commitment to the Linux operating system last year, IBM will add Power Systems Linux to the Power Systems services already available for AIX and IBM iSeries servers at 54 IBM Innovation Centres and Client Centres. This will enable Linux systems to better use IBM's Power8 parallel processing and advanced virtualisation. Read more

How Red Hat can catch the developer train

Outside the operating system, according to AngelList data compiled by Leo Polovets, these developers go with MySQL, MongoDB, or PostgreSQL for their database; Chef or Puppet for configuration; and ElasticSearch or Solr for search. None of this technology is developed by Red Hat. Yet all of this technology is what the next generation of developers is using to build modern applications. Given that developers are the new kingmakers, Red Hat needs to get out in front of the developer freight train if it wants to remain relevant for the next 20 years, much less the next two. Read more

Shortlist of open source software used at NASA lab

The offer was too good to be true. Three whole weeks at the NASA Glenn Research Center and an invitation to come back. I could scarcely believe it when I read the email. I immediately forwarded it to my parents with an addition of around 200 exclamation points. They were all for it, so I responded to my contact, Herb Schilling, with a resounding “YES!” Read more
