How to Network for a Job

When most people hear the phrase “job networking,” they think of those white collar career type jobs that may eventually lead to someone becoming a CEO or owner of a big company. However, whether you are looking for a job in a top 500 company, or simply looking for a job with a construction company, as a cook, or as a teacher here are some helpful tips on how to network for a job.

How to Network for a Job in 6 Easy Steps

Build a Network Before Your Actually Need One

The minute you decide on the type of job that you really like, you should start building a network of people who can offer advice, let you know about job openings, and will spread the word when you are ready to start the job of your choice. Build your network of people in the trade or business you are interested in, related businesses, and people who have influence in the community, as well as people with whom you may share other interests.

Maintain Your Network

Once you have a network in place, begin maintaining your network. Call or email the people regularly just to ask how they are Continue reading

AI and Trivia

I didn’t get a chance to attend Networking Field Day Exclusive at Juniper NXTWORK 2019 this year but I did get to catch some of the great live videos that were recorded and posted here. Mist, now a Juniper Company, did a great job of talking about how they’re going to be extending their AI-driven networking into the realm of wired networking. They’ve been using their AI virtual assistant, named “Marvis”, for quite a while now to solve basic wireless issues for admins and engineers. With the technology moving toward the copper side of the house, I wanted to talk a bit about why this is important for the sanity of people everywhere.

Finding the Answer

Network and wireless engineers are walking storehouses of useless trivia knowledge. I know this because I am one. I remember the hello and dead timers for OSPF on NBMA networks. I remember how long it takes BGP to converge or what the default spanning tree bridge priority is for a switch. Where some of my friends can remember the batting average for all first basemen in the league in 1971, I can instead tell you all about Continue reading

Run the Antidote network emulator on KVM for better performance

Antidote is the network emulator that runs the labs on the Network Reliability Labs web site. You may install a standalone version of Antidote on your personal computer using the Vagrant virtual environment provisioning tool.

In this post, I show you how to run Antidote on a Linux system with KVM, instead of VirtualBox, on your local PC to achieve better performance — especially on older hardware.

Why use KVM instead of VirtualBox?

Antidote runs emulated network nodes inside a host virtual machine. If these emulated nodes must also run on a hypervisor, as most commercial router images require, then they are running as nested virtual machines inside the host virtual machine. Unless you can pass through your computer’s hardware support for virtualization to the nested virtual machines, they will run slowly.

VirtualBox offers only limited support for nested virtualization. If you are using a Linux system, you can get better performance if you use Libvirt and KVM, which provide native support for nested virtualization.

When to use VirtualBox

If you plan to run Antidote on a Mac or a PC, you should use Antidote’s standard installation with VirtualBox¹. Vagrant and VirtualBox are both cross-platform, open-source tools.

Worth Reading: the Lure of the Easy Button

Russ White wrote a great blog post explaining why you have to understand the problem you’re solving instead of blindly believing the $vendor slide deck… or as I said a long time ago, think about how you’ll troubleshoot your network in because you won’t be able to reformat it once it crashes.

Taiji: managing global user traffic for large-scale Internet services at the edge

Taiji: managing global user traffic for large-scale internet services at the edge Xu et al., SOSP’19

It’s another networking paper to close out the week (and our coverage of SOSP’19), but whereas [Snap][Snap] looked at traffic routing within the datacenter, Taiji is concerned with routing traffic from the edge to a datacenter. It’s been in production deployment at Facebook for the past four years.

The problem: mapping user requests to datacenters

When a user makes a request to http://www.facebook.com, DNS will route the request to one of dozens of globally deployed edge nodes. Within the edge node, a load balancer (the Edge LB) is responsible for routing requests through to frontend machines in datacenters. The question Taiji addresses is a simple one on the surface: what datacenter should a given request be routed to?

There’s one thing that Taiji doesn’t have to worry about: backbone capacity between the edge nodes and datacenters— this is provisioned in abundance such that it is not a consideration in balancing decisions. However, there are plenty of other things going on that make the decision challenging:

• Some user requests are sticky (i.e., they have associated session state) and always Continue reading

DXC is betting IT apps and services will stay on-premises

DXC Technology, the massive service provider formed in the 2017 merger of HPE Enterprise Services (formerly EDS) and Computer Sciences Corp., has a new CEO who is focused on shedding distraction businesses and focusing on core businesses of IT outsourcing.That means looking at "strategic alternatives," including the possible divesture of three of its businesses it feels are a distraction and slowing the company’s growth. The company feels most IT apps and services will remain on-premises and will focus on supporting that business.Last week’s conference call with financial analysts to discuss Q2 earnings was the first for new CEO Mike Salvino, who joined the company in September after 22 years at Accenture. DXC did not have a good quarter. The company reported non-GAAP earnings of $1.38 per share, which fell short of the consensus estimate of $1.44 and way down from EPS of $2.02 from the same quarter a year ago. Revenue of $4.85 billion fell short of the analyst estimate of $4.92 billion.To read this article in full, please click here

Librem13v2 TPM upgrade

I have upgraded my TPM firmware on my Librem13v2. Its keys are now safe. \o/

Back in 2017 we had the Infineon disaster (aka ROCA). I’ve written about it before about how bad it is and how to check if you’re affected with a simple tool.

I TAKE NO RESPONSIBILITY IF YOU BRICK YOUR DEVICE OR FOR ANYTHING ELSE BAD HAPPENING FROM YOU FOLLOWING MY NOTES.

Balancing patient security with healthcare innovation | TECH(talk)

Healthcare organizations are one of the most targeted verticals when it comes to cyberattacks. While those organizations must work to secure patients' sensitive data, it can also be helpful to analyze that data to improve patient outcomes. Jason James, CIO of Net Health, joins Juliet to discuss why attackers target healthcare organizations, Google's Project Nightingale and what it means for a tech giant to have access to the medical data of millions of people.
