  • It isnt respected in the hacker community but it is in the HR community for job postings. Sec+ has better content and is a fraction of the cost. And if you want to prove hands-on skills, OSCP is nearly the same price and well respected by everyone.

    In my opinion, CEH has done a tremendous job at branding. Non-cyber tech people all know it. But the content is beginner level stuff.



  • Okay, a lot to unpack here. I work on atmospheric model development. Primarily upper atmosphere models, but have experience with forecasting models as well. Inherently, there is nothing wrong with moving to the cloud for hpc resources. However I do take an issue with the following statement:

    “Cloud-based high-performance computing will accelerate the transition of research into operations by eliminating traditional bottlenecks of on-premise systems,” said NOAA Administrator Neil Jacobs in a statement.

    The bottleneck in forecasting is NOT hardware but unknown and unresolved physical processes. Even at high resolution, forecasting models cannot capture physics and dynamics at spatial scales smaller than the grid of the model. We can make assumptions and use things like machine learning to improve subgrid processes but we cannot fully resolve them without an infinitely small grid, which is impossible. So moving to the cloud will not improve forecasting or the transition of RTO.

    The second issue with this guy is he is a Trump nut hugger. See the following:

  • I have a lightning fact! I am an upper atmosphere physicist and lightning plays a fundamental role in the global electric circuit. Lightning sends charge upward into the ionosphere where the ionosphere distributes the charge horizontally across the globe (Carnegie curve). The return current then trickles down through fair weather regions on Earth, completing the electric circuit!

    I have always appreciated how connected all the layers of the atmosphere are. The ionosphere begins between ~60-90km above the surface, yet lightning still affects it!




  • “Today’s action will begin to correct what is both a human rights abuse and distortive trade practice to improve the welfare of workers everywhere,” US Trade Representative Jamieson Greer said.

    Imagine saying with a straight face from the U.S. of all places that they think the UK and EU need to improve the welfare of their workers. I understand it is related to the forced labor goods coming from China but holy.
