At public service events, groups like Arizona Mesh have been building off grid Meshtastic networks so volunteers can coordinate without depending on cell coverage. That is the real world sweet spot. Lots of people, spotty networks, and you still need quick boring messages like where to meet or who needs help. Meshtastic works here because it is low bandwidth by design, and a text can hop through other nodes to reach farther than you could alone. It also plays nice with phones, so you are not learning a new gadget under stress. Shoutout to folks like Rokland for making it easy to grab compatible devices. Official info is at meshtastic.org. And yep, have a plan. My upcoming app delivers AI guided family strategies.

In Germany, one community built a small solar powered Meshtastic network so they would not be stuck guessing during an emergency. That move is quietly brilliant because a mesh does not need a central tower. A few always on nodes can keep simple texts moving even when the internet is having a bad day. It is basically neighborhood glue, quick check ins, and optional location pings if you want them. The curiosity kicker is power draw. These nodes can sip energy and still cover surprising distance. Shoutout to folks like Seeed Studio making solar nodes accessible. If you want to dig in, start with the official guide at meshtastic.org. And yep, have a plan.

A nonprofit team in the Philippines recently tested a Meshtastic setup and pushed messages a bit over 30 km with just one hop. That is not a hobby flex, that is real coverage when towers are flaky or overloaded. It works because your phone talks to a tiny LoRa node over Bluetooth, then the nodes pass short texts along like a relay team. No SIM card, no WiFi, no drama. The fun detail is the network gets stronger as more people join, since every node can help carry messages. Shoutout to folks like Seeed Studio making solid nodes that are easy to get. More info and the official docs live at meshtastic.org. And yep, have a plan. My upcoming app delivers AI guided family strategies.

It's never been about the issue of safety for these kids out protesting. It's the look at me generation jumping on to the next big Facebook challenge. Virtue signaling is all this generation can muster. Their virtue is tied directly to the number of likes and shares their actions might generate. It's not about doing something because it's the right thing to do. rather, it's about doing something that gains them attention, accolades, or fame. F**k them. Not an ounce of empathy for a single one of them. Bullying, spitefulness, hatred, deceitfulness, breaking the law, is their usual and normal daily actions. On social media they say all the things that make them seem virtuous but it's merely just for the attention.

No one needs fighting dogs, or military dogs and especially NOT those damn vicious Hounds!

"The most foolish mistake we could possibly make would be to allow the subject races to possess arms. History shows that all conquerors who have allowed their subject races to carry arms have prepared their own downfall by so doing. Indeed, I would go so far as to say that the supply of arms to the underdogs is a sine qua non for the overthrow of any sovereignty. So let’s not have any native militia or native police."

No one is marching for the ban on knives yet knives kill more people per year than rifles. 2016, Rifles 374, Knives 1604.

Governor Tom Corbett stated "I am stunned by the senseless tragedy at Franklin Regional High School. Our schools should be places where children can learn and grow without fear of violence"

That doesn't seem like a real-world view of learning and growing. Acknowledgment of risk doesn't mean we have to live in fear. Fear, the hair standing up on the back of our neck is an instinct we have honed over thousands of years. Fear helps us survive. We are creating a false sense of security. Telling kids that schools should always be safe and banning fi****ms will create that safety is a false narrative. Telling kids that they shouldn't fear anything at school is a line of s**t. Kids these days destroy each other on social media, within their own peer groups, physical bullying, cyberbullying, violent crime, these are everyday occurrences in our schools yet they don't make headlines. Kids in schools young adults in college, people, in general, are far too sheltered. Unless something has happened to them personally they feel the risk of harm, violence or criminal activity is non-existent. They say things like, "I don't go to that side of town", "I wouldn't put myself in that situation", "I have nothing of value anyone would want from me". These are example statements of future victims.

The Franklin Regional High School stabbing was a mass stabbing that occurred on April 9, 2014, at Franklin Regional High School in Murrysville, Pennsylvania. Alex Hribal, a 16-year-old sophomore at the school, used a pair of eight-inch kitchen knives to stab and slash 20 students and a security guar...
