Intel Hints At Future Skylake Xeons As Enterprises Cool
The gap in the appetite for new computing technology between enterprises and hyperscalers and cloud builders is widening, but no one is talking about causality quite yet even though there is probably some link between the rise of clouds and more conservative spending on the part of enterprises.
But there is, perhaps, another cause. It could just be that the growth in traditional computing in the enterprise that is dedicated to things like print, file, web, email, and database serving is now less than the Moore’s Law increases that are enabled by process shrinks at the fabs run by Intel. …

The Network Is Reliable and Other Stories
I was cleaning my Blog Post Ideas Evernote notebook and found these gems hidden deep inside its bowels:
I still haven’t found the presentation in which someone (from Facebook?) explained how long DNS information with long-expired TTLs persists in the clients. Relevant links would be highly appreciated.

This Politifact post muddles over whether the Wikileaks leaked emails have been doctored, specifically the one about Tim Kaine being picked a year ago. The post is wrong -- we can verify this email and most of the rest.In order to bloc spam, emails nowadays contain a form of digital signatures that verify their authenticity. This is automatic, it happens on most modern email systems, without users being aware of it.
This means we can indeed validate most of the Wikileaks leaked DNC/Clinton/Podesta emails. There are many ways to do this, but the easiest is to install the popular Thunderbird email app along with the DKIM Verifier addon. Then go to the Wikileaks site and download the raw source of the email https://wikileaks.org/podesta-emails/emailid/2986.
As you see in the screenshot below, the DKIM signature verifies as true.
If somebody doctored the email, such as changing the date, then the signature would not verify. I try this in the email below, changing the date from 2015 to 2016. This causes the signature to fail.
There are some reasons DKIM might fail, specifically if the sender uses short keys. This doesn't apply to GMail, which uses strong 2048 bit keys, Continue reading
NANOG 68
NANOG held its 68th meeting in Dallas in October. Here's what I found memorable and/or noteworthy from this meeting.A Brief History of the IANA
October 2016 marks a milestone in the story of the Internet. At the start of the month the United States Government let its residual oversight arrangements with ICANN (the Internet Corporation for Assigned Names and Numbers) over the operation of the Internet Assigned Numbers Authority (IANA) lapse. No single government now has a unique relationship with the governance of the protocol elements of the Internet, and it is now in the hands of a community of interested parties in a so-called Multi-Stakeholder framework. This is a unique step for the Internet and not without its attendant risks. How did we get here?Managing AWS Infrastructure with Ansible
In this post, I’m going to discuss some concepts behind managing your Amazon Web Services (AWS) infrastructure using Ansible. Ansible is a very popular tool for configuring operating system instances and software; using the concepts and examples provided in this post would allow you to expand your use of Ansible to include—when using AWS—the creation and deletion of the operating system instances themselves, as well as related infrastructure components (like security groups or other services).
Preface
Before I continue, I’d like to first discuss the “fit” of using Ansible for this particular purpose. Ansible doesn’t store the state of managed systems. Perhaps this is due to the agentless architecture; I don’t know. What that means in this particular use case is that you must take other steps to store information you’ll absolutely need like instance IDs, security group IDs, and the like because Ansible itself doesn’t. In my mind, this makes Ansible a less-than-ideal tool for this particular use case. That doesn’t mean Ansible isn’t a good tool; it just means that Ansible may not be the best tool for this particular purpose. (Think of it like this: Yes, you can sometimes unscrew something using a knife, but a screwdriver Continue reading
Why cybersecurity certifications suck
Robert Graham wrote a great blog post explaining why so many IT certifications suck.
TL&DR: because they are trivial pursuits instead of knowledge assessment tests… but do read the whole post and compare it to your recent certification experience.
