Visualize Kubernetes Networking with Goldpinger | Tech At Bloomberg
PowerfulSeal was introduced by Bloomberg last year as an open source tool to test Kubernetes clusters. To address the need for troubleshooting and visualizing connectivity issues during experiments with Kubernetes clusters, Pawlikowski has now built a companion tool called Goldpinger, which was recently published as an open source tool and is being presented at KubeCon + CloudNativeCon North America 2018 in Seattle, WA later today.

Coketenna - easy, cheap, effective homemade ADS-B antenna | Radio for Everyone
I named the result "Coketenna", primarily to prevent ambiguity, as "cantenna" can refer to waveguides for WiFi signals made from a Pringles can, secondarily because in an ADS-B context, "cantenna" also refers to solutions made from different diameter food tin cans. Underlying concept and method of operation is essentially the same, only difference is ease of construction with the Coketenna.

Mesh Networking with PyGo and Pylife – Hackster Blog
The hardware device is called the PyGo, and it handles location tracking, alerts, and messaging, via on board mesh networking. While the app to accompany it is dubbed Pylife, which amongst other things, lets you link your PyGo device to your phone and program it. Based around the Espressif ESP32, which provides both Bluetooth and Wi-Fi, along with a Semtech SX1272 that offers LoRa support, perhaps unsurprisingly the internals of the PyGo look a lot like other Pycom boards. With more detailed specifications for the devices showing that it will also have a Bosch BMA423 accelerometer and a Sony CXD5603GF GPS onboard.  mes  networking  wireless  pygo

Good News for Young Strivers: Networking Is Overrated
The point is true but kind of serviceable. Of course you need to accomplish things and not just work on networking. That kind of goes without saying. I think this article misses the potential upside of meeting people outside your circle and finding second level connections and more distribution.

Introduction | Yggdrasil
Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.

Although Yggdrasil shares many similarities with cjdns, it employs a different routing algorithm based on a globally-agreed spanning tree and greedy routing in a metric space, and aims to implement some novel local backpressure routing techniques. In theory, Yggdrasil should scale well on networks with internet-like topologies.

What I learned about St. Louis, Jim Kavanaugh and soccer after one hour in the city - St. Louis Business Journal
tell you this tale not just because I enjoyed the experience, but because of my first impression of the St. Louis business community. If I can stumble into you at a sports bar in Fenton, you’re likely a pretty accessible bunch. Maybe this experience will turn out to be anomalous, but I’m betting it isn’t.
