The Pepsi Syndrome -- or coffee, or coke, or whatever

Sitting in a Border's books using T-Mobile and keep dropping the signal. About the 4th time, I realize its because I'm putting the nice tall cup of iced cola next to the wireless card. 802.11 wireless uses the same frequency as your microwave oven, because that frequency is "unlicensed" (or at least minimally licensed) compared to many others. This is an interesting wavelength because it happens to interact with water molecules. The microwave works by making water molecules move faster -- imparting energy to them. Another way of saying that (thanks to the laws of conservation of energy) is that water molecules absorb energy in that wavelength. If you're following, you'll realize that my tall cola is mostly water, and way too much of it for that minimal wattage to penetrate reliably. Grrrrr......

The truth is, I haven't had much to say that was worthy of more than a basic social media post -- until today. For my current work, I was assigned a new laptop. It's a real powerhouse machine with 14 processor cores and 64 gigs of ram. It should be perfect for running my development environment in a virtual machine, but it wasn't. VirtualBox was barely starting, and no matter how many features I turned off, it could ...... 
  2. 04/04/2020How many Ventilators for the price of those tanks the Pentagon didn't even want?This goes WAY beyond Trump or Obama. This is decades of poor planning and poor use of funds. Certainly it should have been addressed in the Trump, Obama, Bush, Clinton, Bush, and Reagan administrations -- all of which were well aware of the implications of a pandemic. I want a military prepared to help us, not just hurt other people. As an American I expect that with the ridiculous funding of our military might, we are prepared for damn near everything. Not just killing people and breaking things, but ...... 
  3. 01/28/2020Copyright Troll WarningThere's a copyright troll firm that has automated reverse-image searches and goes around looking for any posted images that they can make a quick copyright claim on. This is not quite a scam because it's technically legal, but it's run very much like a scam. This company works with a few "clients" that have vast repositories of copyrighted images. The trolls do a reverse web search on those images looking for hits. When they find one on a site that looks like someone they can scare, they work it like ......
