Tricks A Dumb Grid Can Play

Inauguration Day in Brookville, Pennsylvania arrived with a bang. Within minutes after Donald Trump swore to preserve, protect, and defend the constitution of the United States, the 911 calls began.  In one house, light bulbs were exploding.  Another resident reported that a power strip was smoking.  At another house, the siding was on fire, and at yet another the electric meter was engulfed in flames.  The main radio transmitter at the police station tripped out, so the 911 call center…

What Are the Rules of Cyberwarfare?

We are now well into the era of cyberwarfare—the use of computers and computer networks in military, terrorist, and diplomatic conflicts.  But to judge by the recent tiff between President Obama and Russian President Vladimir Putin, neither the U. S. nor Russia has figured out exactly how to use these new weapons, or how to defend against them effectively. Last July, Wikileaks unleashed a flood of embarrassing emails hacked from the Democratic National Committee, leading to the resignation of that…

3 Takeaways from IoPP’s Packaging Machinery Course

I recently completed the IOPP Packaging Machinery Basics course at Frain Industries in Chicago, a “survey course” that introduced attendees to a wide range of types of packaging machinery. The course is designed for engineers who work on the design side of packaging, as many packaging professionals have minimal experience working with packaging machinery. This is in large part due to machinery is marginally covered or not taught in many packaging engineer degree programs. Three Course Highlights/TakeawaysNow that I’m a…

The Apache Traffic Server Project’s Next Chapter

By Bryan Call, Yahoo Distinguished Software Engineer, Apache Traffic Server PMC Chair  This post also appears on the ATS blog, https://blogs.apache.org/trafficserver.

Bringing the Viewer In: The Video Opportunity in…

By Satender Saroha, Video Engineering Virtual reality (VR) 360° videos are the next frontier of how we engage with and consume content. Unlike a traditional scenario in which a person views a screen in front of them, VR places the user inside an immersive experience. A viewer is “in” the story, and not on the sidelines as an observer. Ivan Sutherland, widely regarded as the father of computer graphics, laid out the vision for virtual reality in his famous speech,…

Open-sourcing Pulsar, Pub-sub Messaging at Scale

By Joe Francis and Matteo Merli, Yahoo Platforms Pub-sub messaging is a very common design pattern that is increasingly found in distributed systems powering Internet applications. These applications provide real-time services, and need publish-latencies of 5ms on average and no more than 15ms at the 99th percentile. At Internet scale, these applications require a messaging system with ordering, strong durability, and delivery guarantees. In order to handle the “five 9’s” durability requirements of a production environment, the messages have to…

90% of Municipal Engineering is Communication – UrbanWorkbench

I’m regularly reminded of the importance of communication as a part of municipal #engineering as I provide updates on projects and operations to decision-makers. Unfortunately, most university programs in engineering, and many junior level positions fail to prepare graduates and young engineers for this reality. Design work, physics, materials, mechanics, chemistry, and hydraulics are foundational aspects of an engineering career, but success comes through effective communication. The ability of an engineer to convey important information such as risks, options, budgets,…
