THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF CENTRAL / SOUTHERN PLAINS INTO PORTIONS OF THE MIDWEST / OHIO VALLEY. AREAS WILL INCUDE:
-Southern MN, Eastern NE, IOWA
-Middle MS Valley into the OH Valley
-Far northeast NM, West into North TX. OK. Southern KS
When the Storm Prediction Center states "SLIGHT RISK" it means:

-Scattered Severe Storms Possible
-Short Lived and/or Not Widespread
-Isolated Intense Storms Possible

"Slight" DOES NOT mean "small risk"

NJ just had EF-0 and EF-1 tornadoes on 6/13/19 on a NON RISK day.

1. Q: The supervision on the #Chinese Internet is very strict. Will the use of #HoloPorts be restricted by the Chinese #firewall?

A: The HoloPort network should be pretty resilient, even in the face of the Great #Firewall, as the asynchronous ++
2. ++ capabilities of #Holochain allow things (application processing) to function independently on each side of the wall. Thus, ANY node that can communicate across the partition, for example, a #satellite connection, allows everything else to #synchronize with that node. An ++

That said, this is a complicated question, as government censorship is a cat-and-mouse game, and not one that we are focused on specifically. Our aim is to help ++

A thread with some of the story of the “battery card” - the first pirate card sold for hacking DirecTV in the mid 1990s.

#tvpiratehistory
The battery card was a PCB slightly longer than a credit card, with chips on it to emulate a smartcard. Visible on the top of the card when inserted in a satellite receiver was a coin cell-type 3V battery.
Because the chips are thicker than a smartcard, the board would extend out of the cardslot to make room for the chips. Inside the satellite receiver, the battery card emulated an original smartcard. The satellite receiver wouldn’t know the difference.
