Your Cheese Moved a Long Time Ago

I was recently on a panel at the Event-Driven Automation Meetup at LinkedIn in Sunnyvale, CA, and we all had a really good hour-long conversation about automation. What really made me happy was that nearly the entire conversation focused on bringing the same principles that companies like LinkedIn and Facebook use on their network to smaller organizations, making them practical for more widespread use. Nina Mushiana of @LinkedIn says "Anything that can be documented should be automated".

Your Cheese Moved a Long Time Ago

I was recently on a panel at the Event-Driven Automation Meetup at LinkedIn in Sunnyvale, CA, and we all had a really good hour-long conversation about automation. What really made me happy was that nearly the entire conversation focused on bringing the same principles that companies like LinkedIn and Facebook use on their network to smaller organizations, making them practical for more widespread use.

One particular topic that came up was one I’ve struggled with for the past few years; What about Day 2 of network automation? So, we manage to write some Ansible playbooks to push configuration files to switches - what’s next? Often this question isn’t asked. I think the network automation conversation has progressed to the point where we should all start asking this question more often.

I believe that the network engineering discipline is at a crossroads, and the workforce as a whole needs to make some changes and decisions in order to stay relevant. Those changes are all based on the following premise:

Decoding FSK

Something I’ve been playing with lately is software defined radio with GNURadio. I’m not good at it yet, but I’ve managed to decode the signals from a couple of things.

This is my step-by-step for how I decoded data from a boiler thermostat. I’m not saying it’s the best way, or even a good way. But it’s what got me there.

0. Find the frequency

Often this is written on the device itself. Other times it’s in the manual. If not, then more research is needed, such as by trying to find the manufacturer on fcc.gov or similar.

In this case it was easy. The manual said “868 MHz”, which is in the SRD860 band.

1. Capture some data

When I poked at the controls of the thermostat, saying “please make the room 25 degrees”, the thermostat must send this data to the boiler. I could hear the boiler start up and shut down, so there must be something sent between me pressing the buttons and I heard the results.

I started by centering around 868.5 Mhz with 1Msps. The minimum for the RTL-SDR is 900ksps, so even if you wanted to see less than 1MHz you need Continue reading

Most notable tech leaders delivering 2017 college commencement addresses

You’d think ponying up for a technology leader to be your school’s commencement day speaker would be so much less of a hassle than going with a high profile politician such as President Donald Trump or his rival Hillary Clinton, yet 2017 appears to be a lean year for top techies on the college/university commencement circuit.This seems especially true for tech leaders in enterprise networking and IT, whereas in the past the heads of companies such as Cisco, IBM and Salesforce.com have commanded the commencement day stage at top schools.To read this article in full or to leave a comment, please click here

More high-end GPUs are now compatible with Dell’s 8K monitor

Getting 8K displays to work with Windows 10 PCs can be difficult, as Dell is finding out.But playing with 8K on PCs is a discovery process for Dell, which shipped the first-ever 8K display -- the Dell 32 UltraSharp 8K Monitor -- last week. The small initial stock of the US$5,000 display sold out in a few days.The display won't work on all PCs and needs specific hardware and display ports. But Dell is finding out that more hardware than it originally thought can handle 8K graphics, including AMD's Radeon Pro WX 7100 workstation GPU.To read this article in full or to leave a comment, please click here

Fujitsu Takes On IBM Power9 With Sparc64-XII

While a lot of the applications in the world run on clusters of systems with a relatively modest amount of compute and memory compared to NUMA shared memory systems, big iron persists and large enterprises want to buy it. That is why IBM, Fujitsu, Oracle, Hewlett Packard Enterprise, Inspur, NEC, Unisys, and a few others are still in the big iron racket.

Fujitsu and its reseller partner – server maker, database giant, and application powerhouse Oracle – have made a big splash at the high end of the systems space with a very high performance processor, the Sparc64-XII, and a …

Worth Reading: Security Orchestration and Incident Response

Last month at the RSA Conference, I saw a lot of companies selling security incident response automation. Their promise was to replace people with computers ­– sometimes with the addition of machine learning or other artificial intelligence techniques ­– and to respond to attacks at computer speeds. While this is a laudable goal, there’s a fundamental problem with doing this in the short term. You can only automate what you’re certain about, and there is still an enormous amount of uncertainty in cybersecurity. Automation has its place in incident response, but the focus needs to be on making the people effective, not on replacing them ­ security orchestration, not automation. —Schneier on Security

4 reasons Cisco’s IoT forecast is right, and 2 why it’s wrong

Peter Corcoran, Ph.D., who describes himself as long-term IoT skeptic, published a research paper recently on arXiv.org—Third time is the charm – Why the World just might be ready for the Internet of Things this time around (pdf)—in which he speculates that this incarnation of the Internet of Things (IoT) may succeed.Technologies often fail on introduction, later to reemerge and become widely adopted. The PC, smartphone and tablet all went through at least one of these cycles.RELATED: IoT catches on in New England fishing town In the early 1990s, the Consumer Electronics Association first tried to promote CEBus, a specification for interconnecting devices in the home that supported multiple physical layers, including twisted pair, coaxial cable, powerline, wireless and even RF.

Critical Xen hypervisor flaw endangers virtualized environments

A critical vulnerability in the widely used Xen hypervisor allows attackers to break out of a guest operating system running inside a virtual machine and access the host system's entire memory.This is a serious violation of the security barrier enforced by the hypervisor and poses a particular threat to multi-tenant data centers where the customers' virtualized servers share the same underlying hardware.The open-source Xen hypervisor is used by cloud computing providers and virtual private server hosting companies, as well as by security-oriented operating systems like Qubes OS.The new vulnerability affects Xen 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x and has existed in the Xen code base for over four years. It was unintentionally introduced in December 2012 as part of a fix for a different issue.To read this article in full or to leave a comment, please click here
