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..

What does the Ubuntu Phone need to succeed?

Casual Programming and Linux Screen-Recorders

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.

In a bold move today Ubuntu have announced plans to move forward with an Ubuntu Phone which it is touting the interface is the difference here. This is a big statement in a marketplace which has been owned by Apple and Google for the last 3 to 4 years.

Building your own cloud using OwnCloud on Ubuntu.

Filed under
Linux

Unless you’ve been under a rock or are the type of Luddite who thinks the pen and paper is modern hi tech, you cannot fail to have heard about the most miss used expression on the Internet, the cloud. It’s a buzzword which every ill equipped marketing goon has latched his crayon’s onto and will mention in every presentation ever.

Put simply the cloud is the image used when tech people wanted to display the Internet outside their own network, this turned into a location firstly where data could be stored and more recently where “Big Data” is stored.. Honestly I have no idea who comes up with this stuff.

Now that some of us are already enjoying the recently released GNOME 3.22 desktop environment, the GNOME developers are hard at work to improve the GNOME apps and core components by either adding new exciting features and technologies or improving existing ones.

  • Tech, talent and tools: The secret to monetizing open-source
    “In California during the gold rush, you didn’t make money digging for gold; you made money selling shovels,” said Mehta. A fitting metaphor for the idea that investing in talent and tools, especially tools, is how to turn a profit. The actual data, databases, algorithms and so on would be open source. Money would come from the tools to use that technology to benefit specific areas, such as automation of healthcare. And healthcare is a good place to start. “Big Data is all about making life cheaper, better. … If we forget about how to solve problems for humans, we’ve lost. We want to be known for enriching life,” said Mehta.
  • Changing the way we design for the web
    On the one hand, open source should mean lower cost of entry for people from poorer communities (like me, growing up). But on the other, I feel it is hard to contribute when under- or unemployed. I had a grant to work on the Web Animations API documentation, but I can't do as much as I'd like with other animation features (motion paths, advanced timing functions) because I need to spend a lot of time working on my own business, getting paid. Essentially this leads to an awkward model where the only contributors are employed programmers—and when it comes to open source animation or design APIs, platforms, etc, this lack of user input really starts to show. Or, the only products with thriving open source development teams are those that have financially lucrative futures, turning the open source software (OSS) model into a capitalist one.

    I thought I would put together a quick “installation” review of a product called CloudReady by neverware. What is CloudReady? CloudReady is basically a project to bring Chromium OS to those who would like to convert traditional laptops into Chromebook-like devices. I stumbled on them several months ago and finally decided to see how hard it was to install Chromium OS and how functional it actually was as a Chromebook-like device. I have a few low end (netbook-like) devices and I have been trying to figure out how I could make them functional for my boys, I thought this might be the solution.

  • Cloudera Delivers Release Built on Apache Spark 2.0, and Advances Kudu
    Cloudera, focused on Apache Hadoop and other open source technologies,has announced its release built on the Apache Spark 2.0 (Beta), with enhancements to the API experience, performance improvements, and enhanced machine learning capabilities. The company is also working with the community to continue developing Apache Kudu 1.0, recently released by the Apache Software Foundation, which we covered here. Kudu is an open source columnar storage engine built for the Apache Hadoop ecosystem designed to enable flexible, high-performance analytic pipelines. Taken together, Cloudera's new tools are giving it more diverse kinds of presence on the Big Data scene. Cloudera claims it was the first Hadoop big data analytics vendor to deliver a commercially supported version of Spark, and has participated actively in the open source community to enhance Spark for the enterprise through its One Platform Initiative. "With Spark 2.0, organizations are better able to take advantage of streaming data, develop richer machine learning models, and deploy them in real time, enabling more workloads to go into production," the company reports.

  • Machine Learning with Python
    I first heard the term “machine learning” a few years ago, and to be honest, I basically ignored it that time. I knew that it was a powerful technique, and I knew that it was in vogue, but I didn’t know what it really was— what problems it was designed to solve, how it solved them and how it related to the other sorts of issues I was working on in my professional (consulting) life and in my graduate-school research. But in the past few years, machine learning has become a topic that most will avoid at their professional peril. Despite the scary-sounding name, the ideas behind machine learning aren’t that difficult to understand. Moreover, a great deal of open-source software makes it possible for anyone to use machine learning in their own work or research. I don’t think it’s an overstatement to say that machine learning already is having a huge impact on the computer industry and on our day-to-day lives.
