Post-Pandemic Healthcare Innovations

They say there is always a silver lining in every bad thing that happens. Well for some people 2020 was the worst year of their lives. People lost their loved ones, lost their entire businesses and a lot of bad things happen. However even in such drastic times there was silver lining for the future. The pandemic has forced scientists and doctors to come up with healthcare innovations that would help the work way beyond the time of the pandemic. There were many healthcare innovations that were discussed before the pandemic however they were only put to use in urgency once the pandemic hit.

Let’s take a look at the healthcare innovations that we may keep seeing in the post pandemic times.

Innovative Mindset 

In order to keep the innovations coming, the doctors, scientists and researchers should keep an innovative mindset. Without the right mindset you will never be able to carry on with the innovations after the pandemic. So in order to keep the innovations coming after the pandemic, having an innovative mindset is very important.

Remote Communication

The pandemic has shown us that remote communication can be very helpful. People used to believe that face to face communication Continue reading

Intel unveils new type of network accelerator chip

Intel on Monday expanded its network processor roadmap with the announcement of the Infrastructure Processing Unit (IPU). Think of it as the next step in the SmartNIC market, because Intel does.The announcement was made at the Six Five Summit 2021, where Navin Shenoy, the head of Intel's Data Center Group, announced its intention to create the new processor family specifically for cloud workloads.There has been a move toward dedicated networking chips, called SmartNICs, that offload the work of network traffic processing from the CPU, thus freeing up the CPU to do its primary task. Mellanox released one in 2019 and was soon bought by Nvidia. Xilinx released one a year later and will soon be under the ownership of AMD.To read this article in full, please click here

Forget Mesos And OpenStack, Hashi Stack Is The New Next Platform

While a lot of software for creating and managing scale comes out of supercomputing centers, hyperscalers, and the largest public cloud builders, there is still plenty of innovation being done by people who need to tackle scale outside of these upper echelon organizations. …

Enable secure access to applications with Cloudflare WAF and Azure Active Directory

Cloudflare and Microsoft Azure Active Directory have partnered to provide an integration specifically for web applications using Azure Active Directory B2C. From today, customers using both services can follow the simple integration steps to protect B2C applications with Cloudflare’s Web Application Firewall (WAF) on any custom domain. Microsoft has detailed this integration as well.

Cloudflare Web Application Firewall

The Web Application Firewall (WAF) is a core component of the Cloudflare platform and is designed to keep any web application safe. It blocks more than 70 billion cyber threats per day. That is 810,000 threats blocked every second.

Enable secure access to applications with Cloudflare WAF and Azure Active Directory

The WAF is available through an intuitive dashboard or a Terraform integration, and it enables users to build powerful rules. Every request to the WAF is inspected against the rule engine and the threat intelligence built from protecting approximately 25 million internet properties. Suspicious requests can be blocked, challenged or logged as per the needs of the user, while legitimate requests are routed to the destination regardless of where the application lives (i.e., on-premise or in the cloud). Analytics and Cloudflare Logs enable users to view actionable metrics.

The Cloudflare WAF is an intelligent, integrated, and scalable solution to protect business-critical Continue reading

DDoS mitigation using a Linux switch

Linux as a network operating system describes the benefits of using standard Linux as a network operating system for hardware switches. A key benefit is that the behavior of the physical network can be efficiently emulated using standard Linux virtual machines and/or containers.

In this article, CONTAINERlab will be used to create a simple testbed that can be used to develop a real-time DDoS mitigation controller. This solution is highly scaleable. Each hardware switch can monitor and filter terabits per second of traffic and a single controller instance can monitor and control hundreds of switches.

Create test network

The following ddos.yml file specifies the testbed topology (shown in the screen shot at the top of this article):

name: ddos
topology:
  nodes:
    router:
      kind: linux
      image: sflow/frr
    attacker:
      kind: linux
      image: sflow/hping3
    victim:
      kind: linux
      image: alpine:latest
  links:
    - endpoints: ["router:swp1","attacker:eth1"]
    - endpoints: ["router:swp2","victim:eth1"]

Run the following command to run the emulation:

sudo containerlab deploy ddos.yml

Configure interfaces on router:

interface swp1
 ip address 192.168.1.1/24
!
interface swp2
 ip address 192.168.2.1/24
!

Configure attacker interface:

ip addr add 192.168.1.2/24 dev eth1
ip route add 192.168.2.0/24 via 192.168.1. Continue reading

Successful Strategies for Building and Growing IXPs

Insights from a comparative study launched today To bring faster, affordable, and resilient connectivity to people, local Internet stakeholders often turn to Internet exchange points (IXPs). They’re a critical digital infrastructure where networks come together to connect and exchange Internet traffic. IXPs help keep domestic Internet traffic local, reducing transit costs, lag time, and providing […]

What’s New in the Ansible Content Collection for Kubernetes – 2.0

As the adoption of containers and Kubernetes increases to drive application modernization, IT organizations must find ways to easily deploy and manage multiple Kubernetes clusters across regions, both residing in the public cloud and/or on-premises, and all the way to the edge. As such, we continue to expand on the capabilities of our Certified Ansible Content Collection for kubernetes.core.

In this blog post, we’ll highlight some of the exciting new changes in the 2.0 release of this Collection.

 

A New Name

Development on the kubernetes.core Collection had historically taken place in the community.kubernetes GitHub repository, which was built off community contributions before Red Hat supported it. That code base served as the source for both Collections. With this release, we have shifted all development to the kubernetes.core GitHub repository. Moving forward, the community.kubernetes namespace will simply redirect to the kubernetes.core Collection. If you are currently using the community.kubernetes namespace in your playbooks, we encourage you to begin switching over to kubernetes.core. This change better reflects that this codebase is a Red Hat supported Collection.

 

Forward-looking Changes

One of the main objectives of our 2.0 release was to Continue reading

OSPF Inter-Process Route Selection

The traditional wisdom claimed that a Cisco IOS router cannot compare routes between different OSPF routing processes. The only parameter to consider when comparing routes coming from different routing processes is the admin distance, and unless you change the default admin distance for one of the processes, the results will be random.

Following Vladislav’s comment to a decade-old blog post, I decided to do a quick test, and found out that code changes tend to invalidate traditional wisdom. OSPF inter-process route selection is no exception. That’s why it’s so stupid to rely on undefined behavior in your network design, memorize such trivia, test the memorization capabilities in certification labs, or read decades-old blog posts describing arcane behavior.

A startup makes IoT sensors, no batteries necessary

A startup founded by two MIT grads says that it can deploy self-powering sensors to handle low-intensity IoT tasks, eliminating the need for batteries or wired electrical supplies, adding a new level of flexibility to IoT deployments.Ben Calhoun and Dave Wentzloff are the founders of Everactive, an IoT-device manufacturing startup whose sensor modules can create their own power from a variety of sources, including indoor solar, thermal gradient differential, and vibrations. The sensors can monitor for temperature, humidity, light levels, vibration, movement, sound, pressure and gas, among other things.To read this article in full, please click here

The uselessness of bash

The way I write automation for personal projects nowadays seems to follow a common pattern:

  1. A command line, that’s getting a bit long
  2. A bash script
  3. Rewrite in Go

Occasionally I add a step between 2 and 3 where I write it in Python, but it’s generally not actually gaining me anything. Python’s concurrency primitives are pretty bad, and it’s pretty wasteful.

Maybe there’s an actually good scripting language somewhere.

I should remember that writing a bash script (step 2) seems to almost never be worth it. If it’s so complicated that it doesn’t fit on one line, then it’ll become complicated enough to not work with bash.

There are two main things that don’t work well. Maybe there are good solutions to these problems, but I’ve not found them.

1. Concurrency

There are no good primitives. Basically only xargs -P and &. It’s annonying when you have an embarrassingly parallelizable problem where you want to run exactly nproc in parallel.

Especially error handling becomes terrible here.

2. Error handling

You can handle errors in bash scripts in various ways:

  1. || operator. E.g. gzip -9 < a > a.gz || (echo "handling error…")
  2. set -e at the top Continue reading

It’s Most Complicated than You Think

It’s not unusual in the life of a network engineer to go entire weeks, perhaps even months, without “getting anything done.” This might seem odd for those who do not work in and around the odd combination of layer 1, layer 3, layer 7, and layer 9 problems network engineers must span and understand, but it’s normal for those in the field. For instance, a simple request to support a new application might require the implementation of some feature, which in turn requires upgrading several thousand devices, leading to the discovery that some number of these devices simply do not support the new software version, requiring a purchase order and change management plan to be put in place to replace those devices, which results in … The chain of dominoes, once it begins, never seems to end.

Or, as those who have dealt with these problems many times might say, it is more complicated than you think. This is such a useful phrase, in fact, it has been codified as a standard rule of networking in RFC1925 (rule 8, to be precise).

Take, for instance, the problem of sending documents through electronic mail—in the real world, there are various Continue reading
