The Danger of Giving Up Social Media Passwords – So Many Other Services Are Connected
"What's the harm in giving up my Twitter password?", you might say, "all someone can do is see my direct messages and post a tweet from me, right?"
Think again. The reality today is that social media services are used for far more than just posting updates or photos of cats. They also act as "identity providers" allowing us to easily login to other sites and services.
We've all seen the "Login with Twitter" or "Continue with Facebook" buttons on various sites. Or for Google or LinkedIn. These offer a tremendous convenience. You can rapidly sign into sites without having to remember yet-another-password.
But...
... if you give your passwords to your social media accounts to someone, they could potentially[1]:

LuaJIT Hacking: Getting next() out of the NYI list
At Cloudflare we’re heavy users of LuaJIT and in the past have sponsored many improvements to its performance.
LuaJIT is a powerful piece of software, maybe the highest performing JIT in the industry. But it’s not always easy to get the most out of it, and sometimes a small change in one part of your code can negatively impact other, already optimized, parts.
One of the first pieces of advice anyone receives when writing Lua code to run quickly using LuaJIT is “avoid the NYIs”: the language or library features that can’t be compiled because they’re NYI (not yet implemented). And that means they run in the interpreter.

Another very attractive feature of LuaJIT is the FFI library, which allows Lua code to directly interface with C code and memory structures. The JIT compiler weaves these memory operations in line with the generated machine language, making it much more efficient than using the traditional Lua C API.
Unfortunately, if for any reason the Lua code using the FFI library has to run under the interpreter, it takes a very heavy performance hit. As it happens, under the interpreter the FFI is usually Continue reading

Cisco Unveils New Hardware for Virtual Functions at the Branch

Network Automation and Undifferentiated Heavy Lifting
I got this tweet after publishing the “use Ansible to execute a single command on all routers” blog post (and a few similar comments on the blog post itself)
Or use Python, Netmiko and a simple For loop
I never cease to be amazed by the urge to do undifferentiated heavy lifting in the IT industry.

Put it on your calendar. Cisco Live US is June 25 – 29, 2017, in Las Vegas. This is the largest conference I go to every year, and it’s the highlight of my professional year. I’ve been going for a few years now and enjoy it for the content and camaraderie. What are we doing this year?
We’ll fly in on Friday again and do something. No idea what, but I imagine we’ll throw out an invitation for dinner to the public and meet somewhere. If you’re going to be in town, let me know, and we’ll meet up.
The Saturday Adventure was going to be ham radio related since that’s ARRL Field Day. I reached out to the Las Vegas ham club, and they told me that the clubs out there all go to the top of a mountain to operate. The problem : that mountain is 44.8 miles away from Mandalay. That’s one helluvan Uber ride, so that’s out. I looked at some other epic sites like the Grand Canyon and Hoover Dam, but, based on past participation, the time requirements for those don’t make the cut for the group. We probably need to meet Continue reading
Launching an Open Source Book Project
In my list of planned 2017 projects, I mentioned that one thing I’d like to do this year is launch an open source book project. Well, I’m excited to announce The Open vSwitch Cookbook, an Apache 2.0-licensed book project aimed at providing “how to” recipes for Open vSwitch (OVS).
Portions of the book are already available, with more content being added soon (more on that in a moment).
I’m using GitBook as the publishing platform; this allows me to write in Markdown and publish to a variety of formats. I’ll only be publishing to HTML at first; other formats may come down the road. I chose GitBook for a few reasons:
- It’s free for open source projects. This book, as well as the software that is its focus, are both open source projects.
- As I mentioned already, I can use Markdown for all the content.
- It allows me to store the book in a Git repository and use standard Git workflows.
I decided against using GitBook to host the Git repository for the book. Instead, the book’s source is found on GitHub. This enables collaboration on the book’s content—an aspect of this project that I think Continue reading

Reaction; Do we really need a new Internet?
The other day several of us were gathered in a conference room on the 17th floor of the LinkedIn building in San Francisco, looking out of the windows as we discussed some various technical matters. All around us, there were new buildings under construction, with that tall towering crane anchored to the building in several places. We wondered how that crane was built, and considered how precise the building process seemed to be to the complete mess building a network seems to be.
And then, this week, I ran across a couple of articles arguing that we need a new Internet. For instance—
What we really have today is a Prototype Internet. It has shown us what is possible when we have a cheap and ubiquitous digital infrastructure. Everyone who uses it has had joyous moments when they have spoken to family far away, found a hot new lover, discovered their perfect house, or booked a wonderful holiday somewhere exotic. For this, we should be grateful and have no regrets. Yet we have not only learned about the possibilities, but also about the problems. The Prototype Internet is not fit for purpose for the safety-critical and socially sensitive types of Continue reading
