Even before the coronavirus pandemic hit, Intel, the dominant maker of processors for servers on the planet, was rejiggering its product roadmaps behind the scenes in conjunction with its largest OEM partners as well the hyperscalers and large public cloud builders that drive about a third of its revenues these days. …

Another long night. I was working on my perfect, bug-free program in C, when the predictable thing happened:
$ clang skynet.c -o skynet
$ ./skynet.out
Segmentation fault (core dumped)
Oh, well... Maybe I'll be more lucky taking over the world another night. But then it struck me. My program received a SIGSEGV signal and crashed with "Segmentation Fault" message. Where does the "V" come from?
Did I read it wrong? Was there a "Segmentation Vault?"? Or did Linux authors make a mistake? Shouldn't the signal be named SIGSEGF?
I asked my colleagues and David Wragg quickly told me that the signal name stands for "Segmentation Violation". I guess that makes sense. Long long time ago, computers used to have memory segmentation. Each memory segment had defined length - called Segment Limit. Accessing data over this limit caused a processor fault. This error code got re-used by newer systems that used paging. I think the Intel manuals call this error "Invalid Page Fault". When it's triggered it gets reported to the userspace as a SIGSEGV signal. End of story.
Or is it?
Martin Levy pointed me to an ancient Version 6th UNIX documentation on "signal". This is Continue reading
One of the readers commenting the ideas in my Disaster Recovery and Failure Domains blog post effectively said “In an active/passive DR scenario, having L3 DCI separation doesn’t protect you from STP loop/flood in your active DC, so why do you care?”
He’s absolutely right - if you have a cold disaster recovery site, it doesn’t matter if it’s bombarded by a gazillion flooded packets per second… but how often do you have a cold recovery site?

My blog was at https://r2079.wordpress.com and its now moved to https://r2079.com. Why this change?
First and Foremost – Thrill and Challenge
Secondly – Customization and Cost
Don’t get me wrong, I dint migrate because I wanted to get into web development, its not the case and Am not even at intermediate Level there!
Why – This is a custom domain. This is hosted with Route53 Amazon, WordPress is build on AWS custom instance. The Reasons are very simple
So, This is where it is, I will try to maintain the website now and see how this goes, Till now Infrastructure was maintained and patched by WordPress , from now probably i have to take care of it.
Monitoring is the topic for Day Two Cloud. Before you skip because you think it's boring, this conversation may change your mind. We dig into what's necessary to effectively monitor cloud-native and microservices applications to help you run infrastructure smoothly, improve troubleshooting, and anticipate issues before they affect performance or services. Our guest is Josh Barratt, Senior Principal Engineer at Twilio.

The indomitable Greg Ferro joins this episode of the Hedge to talk about the path from automated to autonomic, including why you shouldn’t put everything into “getting automation right,” and why you still need to know the basics even if we reach a completely autonomic world.
We introduced VMware NSX to the market over seven years ago. The platform has helped thousands of customers worldwide transform their network and bring the public cloud experience on-premises. This resulted in higher levels of automation and insight, which, in turn, saved time and money. However, as customers continued to drive new use cases and requirements, we wanted to ensure NSX was completely future-ready; hence NSX-T was born.
NSX-T is the next generation of network virtualization and security platform with a complete L2-L7 suite of services, delivering switching, routing, firewalling, analytics, and load balancing entirely in software. Unlike NSX-V, NSX-T supports a variety of heterogeneous endpoints such as VMs, containers, and bare metal servers. The platform enables a wide range of use-cases in intrinsic security, networking and security for multi-cloud and modern apps, and network automation. The past few releases delivered many new networking and security innovations on NSX-T, prominent among these are the ultimate crown jewels of the platform – NSX Intelligence, Federation, and NSX Distributed IDS/IPS.
Migrating from NSX for vSphere to NSX-T is top of mind for customers that need to transition. Here are answers to some questions that you, Continue reading
