Helpdesk Skills Fit the Bill

I saw a great tweet yesterday from Swift on Security that talked about helpdesk work and how it’s nothing to be ashamed of:

I thought it was especially important to call this out for my readers. I’ve made no secret that my first “real” job in IT was on the national helpdesk for Gateway Computers through a contractor. I was there for about six months before I got a job doing more enterprise-type support work. And while my skills today are far above what I did when I started out having customers search for red floppy disks and removing helper apps in MSCONFIG, the basics that I learned there are things I still carry with me today.

Rocket Science

Most people have a negative outlook on helpdesk work. They see it as entry-level and not worth admitting to. They also don’t quite understand Continue reading

Intel claims sustainability for its custom chip that mines bitcoins faster than GPUs

Intel this week announced details of its new Blockscale ASIC chip designed specifically for more efficient blockchain computing than CPUs or GPUs. It first said it was making such a chip just two months ago.Blockscale is specifically designed to process the Secure Hash Algorithm-256 (SHA-256), which is used by blockchain, and the performance is phenomenal, at least on paper. Blockscale has a hash rate operating speed of up to 580GH/s, or gigahashes per second.To read this article in full, please click here

VPC Endpoints – AWS

Who Should Read: If you are interested in VPC Endpoints or if you want to know more about AWS VPC services please continue.

I have been trying to understand endpoint services and thought I will write up a few posts on it, here are some posts I have written on medium(if you have access), I will port them to the blog by the weekend.

https://towardsaws.com/part-1-aws-advanced-networking-vpc-endpoint-and-types-of-endpoints-covers-exam-44e689d875b

A practical guide to container networking

An important part of any Kubernetes cluster is the underlying containers. Containers are the workloads that your business relies on, what your customers engage with, and what shapes your networking infrastructure. Long story short, containers are arguably the soul of any containerized environment.

One of the most popular open-source container orchestration systems, Kubernetes, has a modular architecture. On its own, Kubernetes is a sophisticated orchestrator that helps you manage multiple projects in order to deliver highly available, scalable, and automated deployment solutions. But to do so, it relies on having a suite of underlying container orchestration tools.

This blog post focuses on containers and container networking. Throughout this post, you will find information on what a container is, how you can create one, what a namespace means, and what the mechanisms are that allow Kubernetes to limit resources for a container.

Containers

A container is an isolated environment used to run an application. By utilizing the power of cgroup, namespace, and filesystem from the Linux kernel, containers can be allocated with a limited amount of resources and filesystems inside isolated environments.

New from Cisco: Workplace-safety service, branch office firewall

Cisco has taken the wraps off a new firewall and a technology package it says help enterprises better control hybrid workers' access to corporate resources and to enable a safer, more secure return to the office.On the firewall front, Cisco has rolled out a new security appliance: the 1RU, 17 Gbps throughput Secure Firewall 3100. It is the low end of the 3100 series and meant to lower the barrier to entry, better support small branches and boost VPN performance, Cisco stated. The Cisco Secure Series already included the 3120, 3130, and 3140 devices which support 23Gbps-45Gbps throughputs.To read this article in full, please click here

Device Management From The Ground Up: Part 7 – Resetting Device Passwords

In an ideal world, we would never need to know how to reset passwords on network devices. In my utopia, network documentation would be thorough, updated, and readily available. We do not live in the ideal world, however. It is almost inevitable you will encounter a device that you are unable to properly authenticate to. In this lesson, I cover the steps for accessing a device without a password.

Handling Bursty Traffic in Real-Time Analytics Applications

Dhruba Borthakur Dhruba is CTO and co-founder of Rockset and is responsible for the company's technical direction. He was an engineer on the database team at Facebook, where he was the founding engineer of the RocksDB data store. Earlier at Yahoo, he was one of the founding engineers of the Hadoop Distributed File System. He was also a contributor to the open source Apache HBase project. Note: This post is the third in the series “can spike 10x during Black Friday. There are many other occasions where data traffic balloons suddenly. Halloween causes consumer social media apps to be inundated with photos. Major news events can set the markets afire with electronic trades. A meme can suddenly go viral among teenagers. In the old days of batch analytics, bursts of data traffic were easier to manage. Executives didn’t expect reports more than once a week nor dashboards to have up-to-the-minute data. Though some data Continue reading
