My #SFP #Wizard from #Ubiquiti fresh out of the box had a loose battery connector. So a peek inside was necessary. 🕵️ So it‘s a ESP32-S3 powering this puppy. Seems to be a good target for some custom software. 😁

What the f*** did I just whitness!? This is a absolute fucking mess. Trump and Vance attacking President Zelensʹkyj in the Oval Office. Zelensʹkyj is a far greater man than either of them could ever be! #zelensky #trump #whitehouse #disgrace https://t.co/uc0JbSkCha

We were chatting in the ops room about memorable visits and one I remember with a smile is when I got a call from Greg(my right) our visitor center volunteer reporting an invasion of furry animals. I went up and invited them in for a photo in front of DSS43. It made a great shot!

That the H-axis has a significantly higher shift can be explained by how the carbon fibre is wound. In the case of the Titan submersible, introducing 45° layers in addition to the primary 0° or 90° layers would have provided better stress distribution and improved resistance..9/x

...and structural shifts, possibly due to delamination or adhesive failure between layers. This failure could also be exacerbated by the multi-cure process, where slight imperfections in bonding could grow into weaknesses as stress builds.7/x This can be seen in the RTM Data too:

When surfacing, the rapid reduction in external pressure could trigger a sudden release of stored strain energy as these stress points give way, leading to the loud bang the crew reported. This energy release could happen because the carbon fiber and adhesive bonds might... 3/x

This layered bonding process can create internal stress points between cured layers, especially at the adhesive interfaces. Over time, particularly under deep-sea pressure, micro-failures like delamination (separation between the layers) or adhesive breakdown can develop. 2/x

Some thoughts about the #OceanGate #Titan implosion: In this construction process, every 133 layers of carbon fiber are cured, and glue is applied before the next set of layers is wound. 1/x

Today, my PC was nearly compromised. With just one click, I installed a malicious @code extension. Luckily, I was saved as my PC doesn't run on Windows. Hackers are getting smarter and aren't just targeting beginners. Here's how they do it and how you can protect your coins!
