Cisco Intersight brings cloud management to compute

I don’t think anyone would argue with the premise that data centers have increased significantly over the past decade. Data centers used to be orderly, as each application had its own dedicated hardware and software. This was highly inefficient, but most data centers could be managed with a handful of people. Then something changed. Businesses were driven to improve the utilization of infrastructure and increase the level of agility, and along came a number of technologies such as virtualization, containers and the cloud. Also, organizations started to embrace the concept of DevOps, which necessitates a level of dynamism and speed never seen before in data centers. To read this article in full or to leave a comment, please click here

Worth Reading: Why you shouldn’t use your face to unlock your phone

Today Apple announced its new FaceID technology. It’s a new way to unlock your phone through facial recognition. All you have to do is look at your phone and it will recognize you and unlock itself. At time of writing, nobody outside of Apple has tested the security of FaceID. So this article is about the security of facial recognition, and other forms of biometric identification in general.Historically, biometric identification has been insecure. … If you value the security of your data — your email, social media accounts, family photos, the history of every place you’ve ever been with your phone — then I recommend against using biometric identification. Instead, use a passcode to unlock your phone. —Quincy Larson @ Free Code Camp

Mastering file searches on Linux

There are many ways to search for files on Linux systems and the commands can be very easy or very specific -- narrowing down your search criteria to find what just you're looking for and nothing else. In today's post, we're going to examine some of the most useful commands and options for your file searches. We're going to look into: quick finds more complex search criteria combining conditions reversing criteria simple vs detailed responses looking for duplicate files There are actually several useful commands for searching for files. The find command may be the most obvious, but it's not the only command or always the fastest way to find what you're looking for.To read this article in full or to leave a comment, please click here

On the ‘net: Fragmentation and IPv6

Does this mean we ban all filtering of traffic on the public Internet, imposing the end-to-end rule in earnest, leaving all security to the end hosts? This does seem to be the flavor of the original IPv6 discussions around stateful packet filters. This does not, however, seem like the most realistic option available; the stronger defense is not a single perfect wall, but rather a series of less than perfect walls. Defense in depth will beat a single firewall every time. Another alternative is to accept another bit of reality we often forget in the network engineering world: abstractions leak. The end-to-end principle describes a perfectly abstracted system capable of carrying traffic from one host to another, and a perfectly abstracted set of hosts between which traffic is being carried.

Supercomputing Advancing Too Fast for Key Codes to Keep Pace

The high performance computing world is set to become more diverse over the next several years on the hardware front, but for software development, this new array of ever-higher performance options creates big challenges for codes.

While the hardware advances might be moving too quick for long-standing software to take optimal advantage of, for some areas, things are at a relative standstill in terms of how to approach this future. Is it better to keep optimizing old codes that could be ticked along with the X86 tocks, or does a new architectural landscape mean starting from scratch with scientific codes–even …

Project Jengo Strikes Its First Targets (and Looks for More)

Jango Fett by Brickset (Flickr)

When Blackbird Tech, a notorious patent troll, sued us earlier this year for patent infringement, we discovered quickly that the folks at Blackbird were engaged in what appeared to be the broad and unsubstantiated assertion of patents -- filing about 115 lawsuits in less than 3 years, and have not yet won a single one of those cases on the merits in court. Cloudflare felt an appropriate response would be to review all of Blackbird Tech’s patents, not just the one it asserted against Cloudflare, to determine if they are invalid or should be limited in scope. We enlisted your help in this endeavor by placing a $50,000 bounty on prior art that proves the Blackbird Tech patents are invalid or overbroad, an effort we dubbed Project Jengo.

Since its inception, Project Jengo has doubled in size and provided us with a good amount of high quality prior art submissions. We have received more than 230 submissions so far, and have only just begun to scratch the surface. We have already come across a number of standouts that appear to be strong contenders for invalidating many of the Blackbird Tech patents. This means it is Continue reading

Some Static Site Resources

Over the last few days—prompted perhaps by my article with some additional information on my site migration—a few folks in the community have reached out to me to share some resources they thought I might find useful. In turn, I’d like to share them with you, my readers, in the event you might find them useful as well.

This is (clearly and obviously) not a comprehensive list, but here’s what folks have shared with me over the last few days:

  • Josh Habdas shared this link with me; it’s a write-up he did that involves the use of a Ruby-based tool called s3_website. The main problem I have with this write-up is that it hides too many of the details, preventing (in my opinion) some of the valuable learning that can come from such an effort.
  • This article by Ricardo Feliciano of CircleCI does expose some of the gory details, and might be useful for those considering the inclusion of a CI/CD pipeline in their blogging workflow (like I am).
  • Finally, I found this post describing how to build a multi-region S3+CloudFront setup that would protect your site in the event of a single S3 region being unavailable.

I’ll update this Continue reading

Worth Reading: Hacking through subaudible commands

Chinese researchers have discovered a terrifying vulnerability in voice assistants from Apple, Google, Amazon, Microsoft, Samsung, and Huawei. It affects every iPhone and Macbook running Siri, any Galaxy phone, any PC running Windows 10, and even Amazon’s Alexa assistant. Using a technique called the DolphinAttack, a team from Zhejiang University translated typical vocal commands into ultrasonic frequencies that are too high for the human ear to hear, but perfectly decipherable by the microphones and software powering our always-on voice assistants. This relatively simple translation process lets them take control of gadgets with just a few words uttered in frequencies none of us can hear. —Mark Wilson @ CO.DESIGN

Arista reaches for the hybrid clouds

Many years ago, when Arista Networks was in its infancy, its charismatic and sometimes controversial (at least to the folks at Cisco) CEO talked about how the company’s software-first approach would disrupt the networking industry. Just a few years later, the company stands a $1.7 billion revenue company with a dominant position in the webscale industry and a market cap of over $13 billion, so clearly CEO Jayshree Ullal’s prophecy came true.Arista’s software rigor enabled the company to quickly jump into verticals where low latency and high performance mattered. Also, because of Arista’s software prowess, the company has been able to expand its addressable market to see to the networking needs of dense virtualization and containerized environments, as well as private cloud deployments, and quickly adapt the latest and greatest silicon.To read this article in full or to leave a comment, please click here

What is edge computing and how it’s changing the network

Edge computing allows data produced by internet of things (IoT) devices to be processed closer to where it is created instead of sending it across long routes to data centers or clouds.Doing this computing closer to the edge of the network lets organizations analyze important data in near real-time – a need of organizations across many industries, including manufacturing, health care, telecommunications and finance.“In most scenarios, the presumption that everything will be in the cloud with a strong and stable fat pipe between the cloud and the edge device – that’s just not realistic,” says Helder Antunes, senior director of corporate strategic innovation at Cisco.To read this article in full or to leave a comment, please click here
