In this week's podcast we check in with Troy Hunt from HaveIBeenPwned.com. Troy has done the responsible thing in adding the Ashley Madison dataset to his service -- you can only search for email addresses in the dump after you've verified that you control them. We'll talk to him about why he did that.
"The 14th Amendment is unconstitutional."Of course he didn't say that. What he did say is that the 14th Amendment doesn't grant "birthright citizenship" aka. "anchor babies". And he's completely correct. The 14th Amendment says:
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States"The complicated bit is in parentheses. If you remove that bit, then of course Trump would be wrong, and anchor babies would be guaranteed by the constitution, since it would clearly say that being born in the U.S. grants citizenship.
Kevin Jones (@WebOpsX) wrote a nice post over on the NGINX blog about installing NGINX and NGINX Plus with Ansible.
One of my favorite features of Ansible is that it is completely clientless. To manage a system, a connection is made over SSH, using either Paramiko (a Python library) or native OpenSSH. Another attractive feature of Ansible is its extensive selection of modules. These modules can be used to perform some of the common tasks of a system administrator. In particular, they make Ansible a powerful tool for installing and configuring any application across multiple servers, environments, and operating systems, all from one central location.
Here are a few NGINX Ansible Galaxy Roles

ARM wants to lend a hand to IoT.
Today CloudFlare is introducing a new way to purge the cache using Cache-Tags. Cache-Tags are assigned to cached content via a Cache-Tag response header, and are stored as metadata with cached objects so that global purges take only seconds, targeting a granular, finite set of cached objects.
For example, an e-commerce website can use Cache-Tags to purge all of their catalog images at once, without affecting any of their other assets. A blog can use Cache-Tags to update their JavaScript files in cache, without forcing a cache miss on their CSS. A business can use Cache-Tags to purge cache of all four hundred pages of their blog without purging any of the pages from their core platform.
With 42 data centers around the world, web pages served directly from CloudFlare’s cache are guaranteed to be just a few hops away from any visitor, anywhere. With a little bit of fine tuning, many websites succeed in delivering most of their content from cache, saving a majority of bandwidth on their origin servers. One website even managed to reduce their AWS bill by 96% when they started caching assets behind CloudFlare.
CloudFlare’s cache is powerful, but when a Continue reading
I recently moved from Windows to Linux on my personal laptop and thought I might share my experience. This isn’t directly network related, but hopefully of interest to some portion of the large and diverse PP audience, especially considering recent events in the Microsoft realm. Ignoring that, using Linux ‘at home’ is a great way to learn about […]

The role the SDN control layer plays.
This is a guest repost by Mark Russinovich, CTO of Microsoft Azure (and novelist!). We all benefit from a vibrant competitive cloud market and Microsoft is part of that mix. Here's a good container overview along with Microsoft's plan of attack. Do you like their story? Is it interesting? Is it compelling?
You can’t have a discussion on cloud computing lately without talking about containers. Organizations across all business segments, from banks and major financial service firms to e-commerce sites, want to understand what containers are, what they mean for applications in the cloud, and how to best use them for their specific development and IT operations scenarios.
From the basics of what containers are and how they work, to the scenarios they’re being most widely used for today, to emerging trends supporting “containerization”, I thought I’d share my perspectives to better help you understand how to best embrace this important cloud computing development to more seamlessly build, test, deploy and manage your cloud applications.
In abstract terms, all of computing is based upon running some “function” on a set of “physical” resources, like processor, memory, disk, network, etc., to accomplish a task, whether a Continue reading
When I’m not working (boring right now), reading Everyday Feminism (fascinating*) or spending time with the family (awesome) I’m writing. I’ve three book projects on the go, two of which are taking far too long and rapidly become a chore. The third is the third edition of my F5 iRules book (I’m not shilling – […]

From the very beginning, the walled garden has been the opposite of what those who work on and around the ‘net have wanted. The IETF, and the protocols it has developed over the years, have always been about free and open access to anyone who wants to learn networking, coding, or even just what the latest baseball score for their favorite team. Of course, a number of tech giants (remember Compuserve?) fought to build walled gardens using the tools of the Internet. A user would dial into a modem pool, and access the world through a small portal that would provide a consistent and controlled interface for their entire experience, from email to news to chat to…
The same battle rages in recent times, as well. Phone makers, mobile providers, and even social media networks would desperately like to make your only interface into the global Internet a single O/S or app. From this one app, you’ll be able to talk to your friends, pay your bills, save all your data, and, in general, live your entire life. And for those times when you can’t get to what you want outside the app or social network, they will gladly Continue reading
