Worth Watching: The Economics of the Internet

Old economics explains the new economy well. When we buy something, we spend time and money searching for it, comparing it with other products, negotiating a price, and ensuring that we get what we paid for. This is what economists call ‘transaction costs.’ The internet dramatically reduces these costs, making it cheaper for people, businesses and governments to do business. -via the World Bank

Xen’s latest hypervisor updates are missing some security patches

The Xen Project released new versions of its virtual machine hypervisor, but forgot to fully include two security patches that had been previously made available.The Xen hypervisor is widely used by cloud computing providers and virtual private server hosting companies.Xen 4.6.1, released Monday, is flagged as a maintenance release, the kind that are put out roughly every four months and are supposed to include all bug and security patches released in the meantime."Due to two oversights the fixes for both XSA-155 and XSA-162 have only been partially applied to this release," the Xen Project noted in a blog post. The same is true for Xen 4.4.4, the maintenance release for the 4.4 branch that was released on Jan. 28, the Project said.To read this article in full or to leave a comment, please click here

Should you worry about the Internet of Hackable Things?

If 2015 was the year of the Internet of Things, 2016 could be the year of the hacked Internet of Things. That could mean a lot of headaches for CIOs, whether they're fans of these new devices themselves or will be dealing with employees connecting them at work and managing the potential security exposure that brings. "The issue to date is that devices are vulnerable just by the fact that they exist and can connect to the Internet," says Jerry Irvine, member of the U.S. Chamber of Commerce’s Cybersecurity Leadership Council and CIO of Prescient Solutions. "Anybody can get to a device if you don't secure them properly." To read this article in full or to leave a comment, please click here

How to prevent shadow IT

Stopping the armchair IT folksImage by Mette1977 What do complex IT policies, outdated software and lack of IT-supported services have in common? They all contribute to shadow IT, which occurs when employees circumvent procedures to use unapproved services and software. The last thing employees want to do when working on a project is check in with the IT department, so how can IT provide employees with necessary resources so shadow IT is no longer an issue? These InfoSec professionals share their suggestions for preventing shadow IT before it becomes the new normal. To read this article in full or to leave a comment, please click here

We’ve always been at war with Eastasia

Our media is surprisingly Orwellian, and it's not always due to government control. People practice "doublethink" at their own volition, without a Thought Police. Social media (Twitter, Facebook) are instituting their own private Thought Police. Online journalism now means that the press is free to edit old articles, to change past reporting to conform to new political realities.

Consider the example in the book 1984 regarding the ongoing war between the three superstates of Oceania, Eurasia, and Eastasia (representing English, Russian, and Chinese empires respectively).

At the start of the book, Oceania is at war with Eurasia. They have always been at war with Eurasia. That's the political consensus, and all historic documents agree. However, Winston Smith (the protagonist) remembers a time five years ago when Oceania was instead at war with Eastasia. Winston Smith struggles with philosophical idea of "truth". Which is more true, what everyone knows and what's in the newspapers, or the memories within his head?

Then Ocean's allegiance switched back again. On the sixth day of Hate Week, as crowds gathered to denounce Eurasia, the Party switched enemies to Eastasia. In a particularly rousing speech against their enemy, the speaker was handed a slip of paper, Continue reading

Workaround for virtualenvwrapper for windows postactivate script

Virtualenvwrapper’s windows port (virtualenvwrapper-win) helps to manage your venvs on windows platform, yet it is not so straigtforward about using hooks like postactivate. That is what official documentation has to say about this: Hooks To run some commands after mkvirtualenv you can use hooks. First you need to define VIRTUALENVWRAPPER_HOOK_DIR variable. If it is set mkvirtualenv

Ansible up and running

After much delay – I’ve finally found time to take a look at Ansible.  I’ve spent some time looking at possible platforms to automate network deployment and Ansible seems to be a favorite in this arena.  One of the primary reasons for this is that Ansible is ‘clientless’ (I’m putting that in quotes for a reason, more on that in a later post).  So unlike Chef, Puppet, and Salt (Yes – there are proxy modes available in some products) Ansible does not require an installed client on the remote endpoints.  So let’s get right into a basic lab setup.

While the end goal will be to use Ansible to automate network appliances, we’re going to start with the a more standard use case – Linux servers.  The base lab we will start with is two servers, one acting as the Ansible server and the second being a Ansible client or remote server.  Both hosts are CentOS 7 based Linux hosts.  So our base lab looks like this…

Pretty exciting right?  I know, it’s not, but I want to start with the basics and build from there…

Note: I’ll refer to ansibleserver as Continue reading

Fscking Visual Studio Code JS Hello World

The reason Linux never succeeded on the desktop is the lack of usability testing. Open-source programmers hate users, and created such an ugly baby that only a fanboy could love it. It's funny watching the same thing happen to "Visual Studio Code", Microsoft's answer to the Atom editor. You'd think with Microsoft behind it, that it'd be guided by usability testing. The opposite is true. It spends a lot of time hyping it, but every time I try to use it, I encounter unreasonable hurdles for the simplest of things. It's the standard open-source paradigm -- they only spend effort to make something work in theory without the extra effort to make it usable in practice.

The most common thing you'll want to do is first create a "hello world" program, then debug it. As far as I can tell, there are no resources that'll explain how to do this. So, for JavaScript on Windows, I thought I'd explain how this works.

Firstly, you'll need to install NodeJS and VS Code. Just choose the defaults, it's uneventful.

Secondly, you need to understand how projects work. This is the first hurdle everyone has with an IDE. You don't simply run the Continue reading
