The IoT needs simulation to grow

Without simulation, complex systems would fail. Satellites would not reach an accurate orbit, semiconductor circuits would not function, and bridges would not carry the load. Businesses and governments would not invest in these projects without robust simulation software. And without a simulation proving value and functionality, IoT networks of hundreds of thousands or millions of inexpensive devices adding up to large capital investments will not be built.Researchers from the University of Bologna published an analysis of IoT simulation and a smart cities vehicular transportation system case study (pdf). They recommend a networked simulation of orchestrated simulators that model specific IoT features that fit the diversity of IoT devices and use cases.To read this article in full or to leave a comment, please click here

RFC8200: IPv6 Is an Internet Standard

You wouldn’t believe it – after almost 22 years (yeah, it’s been that long since RFC 1883 was published), IPv6 became an Internet standard (RFC8200/STD86). No wonder some people claim IETF moves at glacial speed ;)

Speaking of IPv6, IETF and glacial speeds – there’s been a hilarious thread before Prague IETF meeting heatedly arguing whether the default WLAN SSID should be IPv6-only (+NAT64). Definitely worth reading (for the entertainment value) over a beer or two.

Top 10 Most Obvious Hacks of All Time (v0.9)

For teaching hacking/cybersecurity, I thought I'd create of the most obvious hacks of all time. Not the best hacks, the most sophisticated hacks, or the hacks with the biggest impact, but the most obvious hacks -- ones that even the least knowledgeable among us should be able to understand. Below I propose some hacks that fit this bill, though in no particular order.

The reason I'm writing this is that my niece wants me to teach her some hacking. I thought I'd start with the obvious stuff first.


Shared Passwords

If you use the same password for every website, and one of those websites gets hacked, then the hacker has your password for all your websites. The reason your Facebook account got hacked wasn't because of anything Facebook did, but because you used the same email-address and password when creating an account on "beagleforums.com", which got hacked last year.

I've heard people say "I'm sure, because I choose a complex password and use it everywhere". No, this is the very worst thing you can do. Sure, you can the use the same password on all sites you don't care much about, but for Facebook, your email account, and your bank, Continue reading

The Skylake Calm Before The Compute Storm

It looks like the push to true cloud computing that many of us have been projecting for such a long time is actually coming to pass, and despite many of the misgivings that many of us have expressed about giving up control of our own datacenters and the applications that run there.

That chip giant Intel is making money as it rolls up its 14 nanometer manufacturing process ramp is not really a surprise. During the second quarter of this year, rival AMD had not yet gotten its “Naples” Epyc X86 server processors into the field, and IBM has pushed …

Worth Reading: Do startup employees make more?

Since the average startup founder who makes it to Series A earns more than a large company employee, many believe that early-stage startup employees also earn more (albeit less than founders). Dustin Moskovitz has even claimed that startup early employees have better earnings prospects than founders. We’ve looked at the data, and this does not seem to be true on average. —Ben West @ 80000hours

Cray buys Seagate’s enterprise storage array business

Supercomputer specialist Cray announced it is acquiring Seagate’s ClusterStor HPC storage array business for an undisclosed sum as part of a strategic deal and partnership. The deal should close in the third quarter. Cray will take over development, manufacturing, support and sales of the ClusterStor product line, picking up 100 Seagate employees in the process. Seagate acquired Xyratex, the maker of ClusterStor for $374 million in 2014. Cray already sells ClusterStor under its Sonexion scale out Lustre arrays. Sonexion is based on ClusterStor, so it simply comes in-house. Cray is the biggest OEM for the ClusterStor line. Even though Cray was already knee deep in ClusterStor, it brought the technology in-house so it can reduce margins and push further on development to align with its strategy, which sounds like it intends to compete with Dell EMC. To read this article in full or to leave a comment, please click here

VMware NSX is something something awesome

At times I have trouble focusing on writing articles for some of the presentations I am exposed to at Tech Field Day. Because of that, I really wanted to try something different. This article is more of my free-formed thoughts about NSX and why I’m excited to deploy it at my current $job. From the time I heard that the NSX team was going to be presenting at TFD15 for 4 hours, I knew that I would be writing this article because. Unfortunately it took me far too long to gather up this half formed thought.

First things first – NSX and Micro-Segmentation

I love the concept of Micro-Segmentation that NSX enables. Think of NSX as a virtual distributed firewall that is integrated with your hypervisor, but it really is so much more. This allows you to connect a security policy directly to the vNIC of your guest VM’s. Attaching it to the VM allows that policy to follow the VM anywhere, and everywhere it goes. You don’t have to worry about inter- or intra-VLAN segmentation as all of that is done on each vNIC. On top of that, NSX’s firewall is PCI DSS 3.2 compliant! Another rather compelling Continue reading
