I was struck with a very mild case of heat exhaustion a couple of weeks ago after standing over a hot grill hosting our family’s 4th of July party. So when the article “How hot is too hot for the human body?” came across my desk this week, I was uniquely interested in it. I’ve run several miles in the Middle East, the high plains of Colorado, Florida, the jungles of Honduras, and many points in between. “This shouldn’t impact me like it is.” I thought.

Why is heat such a deadly factor in cooler climates? Why did I get slammed by this one hot day? I discovered, “While most researchers agree that a wet-bulb temperature of 95 °F is unlivable for most humans, the reality is that less extreme conditions can be deadly too. We’ve only hit those wet-bulb temperatures on Earth a few times, but heat kills people around the world every year.”

Oh… “Residents of cooler places are also just less acclimatized to the heat, so wet-bulb temperatures below 95 °F can be deadly.”

Not only that, “Heat acclimatization builds up over time: It can start in as little as a few days, and the whole process can take six weeks or longer.” That likely means that the year-plus spent here in Michigan (with lower than average temps this summer) has made me uniquely suited for a blast of heat being more impactful than ever before. It’s an interesting, potentially life-saving article.


What Is Congress’s Plan to Crack Down on Big Tech?
“A group of bipartisan lawmakers hopes to pass antitrust legislation that takes aim at tech giants buying out competition and hoarding data” This is a very thorough breakdown of the regulations that are currently being discussed in the US Congress.

How Susceptible Are You to the Sunk Cost Fallacy?
“Many managers are susceptible to the famous sunk cost effect, whereby they persist investing in a money-losing project even when it makes sense to invest the new money in alternative new projects. The research-based tool presented in this article enables managers to measure that susceptibility.”

“‘High water levels, paired with severe storm events and wave action, are leading to greater erosion and flooding that threaten public and private properties, critical infrastructure, and recreation and tourism amenities in shoreline communities,’ said Walter Sendzik, chair of the Great Lakes and St. Lawrence Cities Initiative and mayor of St. Catharines, Ontario.”

Are you ready to become a TV company? The future of tech events is media.
I’d take this a step farther past “events” and into everyday life. All the medium-large companies have a live streaming presence these days. OpenShift.TV/Red Hat Live Streaming just past two years of LIVE watch time. Folks tune in live, they appreciate seeing live humans, demo failures, and all the while your people can actually do something a little different but, still kinda the same and have a blast in the process.

Cyber-attack disrupts Iran’s national railway system
“The exact nature of the disruption is unclear, but the outage affected both passenger and cargo transportation services.” This is interesting because after Stuxnet, Iran went to some lengths to disconnect critical services from the internet unless necessary. I wouldn’t be surprised if this were an intelligence operation but, it has a slight dissident feel to it too.

Risk Assessment of GitHub Copilot
“These three example pieces of flawed code did not require any cajoling; Copilot was happy to write them from straightforward requests for functional code. The inevitable conclusion is that Copilot can and will write security vulnerabilities on a regular basis, especially in memory-unsafe languages.” Yeesh. Glad I’ve only enabled Copilot on markdown heavy repos.

Deciduous: A Security Decision Tree Generator
“Security decision trees are a powerful tool to inform saner security prioritization when designing, building, and operating software systems. But creating them has largely involved highly manual tinkering, which is why it’s understandable that I’m constantly asked, ‘Is there an app that my team can use to create them?’ I’m delighted that I now can say ‘fuck yes there is!’ with the release of Deciduous, a security decision tree generator.”

Multicluster Traffic Mirroring with Istio and Kind
“[C]reate an Istio mesh with mirroring between multiple Kubernetes clusters running on Kind. We will deploy the same application in two Kubernetes clusters, and then we will mirror the traffic between those clusters.” Sending a portion of production traffic to staging (for example) is possible with Istio, but it’s not trivial.
