Russ White wonders if the resurgence of Walled Gardens on the Internet is bad or a good thing. The long-term rise of Facebook, WeChat, Snapchat and other applications seems to be a sustaining trend.

One of my readers sent me a heartfelt email that teleported me 35 years down the memory lane. He wrote:
I only recently stumbled upon your blog and, well, it hurt. It's incredible the amount of topics you are able to talk about extensively and how you can dissect and find interesting stuff in even the most basic concepts.
May I humble ask how on earth can you know all of the things you know, with such attention to detail? Have you been gifted with an excellent memory, magical diet, or is it just magic?
Short answer: hard work and compound interest.

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.

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
