What is Aokigahara ? it sounds like the name of a cool anime show or a character from street fighter right ? Actually it’s a forest located at the northwest base of Mount Fuji in Japan. As we all know Mount Fuji is one of Japans 3 sacred mountains so I find it hard to believe people travel to Aokigahara to commit suicide.
Can’t even hike peacefully
The crazy part is they have workers who go into the forest and find the dead bodies and have to carry them all the way down to the mountain. Then they have to play rock paper scissors to decide who will sleep with the corpse that night. It’s bad luck for a corpse to be alone the first night it’s dead. The spirit will scream all night and the body will go crazy. Japan is known for high suicide rates. Sometimes they have the most suicides in the world.
Yurei making me scared !
Aokigahara is said to be the most haunted place in Japan. Stories are told of screams originating from the forest randomly. To travel in the forest and not get lost you have to use tape to create a trail. GPS and cell phones and compasses don’t work in the forest due to high iron content in the soil or demons as the locals believe. Yurei (Japanese for ghost) are blamed for cutting visitors tape so people will get lost and die in the forest. Screams are also blamed on Yurei because those souls can’t rest or are evil it seems. If you’re near Japan and want to suicide or have one of the scariest hikes in your life then visit Aokigahara.
You may have heard or read the phrase “Routing Table” when referring to a Subscriber. This solution explains what the Routing Table is and how it is generated.An AES IntelliNet Subscriber maintains a list of ID’s, up to eight for the purpose of passing its messages or data packets through, in route to the head end or Central Receiver. The list is generated by listening. Any transmission by any other device on the IntelliNet network at the same frequency and with the same Cipher code that is passed through the Transceiver and decoded by the Subscriber is evaluated. The Subscriber that hears the transmission will extract values contained in the header of the transmission detected.
The extracted information will include the ID of the device currently transmitting the packet along with its Link Layer / Level (LL), NetCon (NC) and Status or fault code. The signal strength of the transmission will also be evaluated. The signal strength evaluation includes whether the Carrier Detect level was reached (CD) and a value that identifies how readable the data was.Upon decoding a packet header, the extracted values are compared with the current list or Routing Table. If the ID is in the list and the values have not changed the Table is left as is.
If there was a change to a value of an ID in the list, the list is modified. If the ID is not in the list, then it is evaluated to determine if it should be in the list. That evaluation includes the signal strength, Status code and whether the LL is equal to or better than what is currently in the list. If the ID rates a place in the list, the list is modified, the Table is sorted and the Subscriber calculates new LL and NC values.
The important thing to take away from this lesson is that the Routing Table is built by listening. Attempts to communicate back to those ID’s in the list, does not occur until the Subscriber has a Data Packet to transmit and only then, if it progresses through the List of ID’s and reaches that ID in the process of using its Routing Table because others in the list before it have failed to have a packet Acknowledge received.
What can be said about Hurricanes that hasn’t been said about about a divorce. They ruin lives are expensive and can be deadly. The worst hurricane so far hit Galveston in 1900.
Apparently city officials never imagined a large hurricane hitting their island so they decided not to build seawalls. Once things were rebuilt everything was raised 17 feet by bringing in more sand and a large seawall was constructed.
Below are the top ten worst hurricanes in the USA since 1851 until 2006.
Back before UL revision 9 came out the NetCom values read 0 to 7. 0 being the best and 7 the worst. After the UL Revision 9 changes the NetCon values changed to 5 to 7. 5 is the best 7 is worst. A NetCom 5 is needed to pass a fire inspection. The detailed explanation is below.
A Subscriber developed before the UL 864 9th Edition Compliant models calculate NetCon differently than the later. Edition 9 compliant Subscribers begin at firmware version 2.6+. The firmware version features typically follows all models. If another model is released with a version 2.6+ or higher, it would include the basic Subscriber functions as any other at that version with specific model variations added as needed. Version 2.6+ was designed to operate in a MultiNet environment and still be able to use NetCon 5 to indicate at least two unique paths exist in the current Routing Table all the way to the MultiNet Receiver/7705i.Earlier firmware than 2.6 was developed around the Single RF head end receiver concept, where they would report their NetCon as 0 if the #1 ID in the Routing Table was reporting a Link Layer/Level (LL) of 0.
RF Head End devices such as the 7003, 7703 or a 7170 IP-Link, are the only devices that can report LL as 0. A pre-V 2.6 Subscriber would report itself as a NetCon of 0, because the ID at the top of the list is a LL 0. In other words, if the #1 ID in the list is the single Stand Alone Receiver, it reports NetCon as 0.A V 2.6+ or higher does not report a NetCon of 0 with a LL as 0 in the #1 position. This prevents the reporting of NetCon 0 when a single IP-Link is at the top of the list. Two IP-Links are required to establish a NetCon of 5. Two IP-Links would in fact constitute two unique paths all the way to the 7705i. A third IP-Link would provide three unique paths, but NetCon would still be calculated as 5 adhering to the Edition 9 algorithm’s rules.
How can there be several IDs at the top preference locations in a Routing Table, which have a Good Signal Quality (SQ) and yet have a NetCon of 7? If NetCon is 7 and there are what appears to be Good SQ IDs at the top of the list, then there is something else that is preventing the Subscriber from considering the ID as Good.It may be that the NetCon of the #1 listed ID has itself got a NetCon of 7. A Subscriber can’t be better than the best (#1) ID listed in its routing table. It may be that there are some faults being reported by the ID, which are not displayed in the information presented to you.Signal Quality is only one factor in determining if a listed ID is “good” to decrement NetCon.
The list of what is considered good:
Signal above a threshold. (SQ=Good) No Faults reported. (i.e. low battery, AC fail) Link Layer better than current LL of this Subscriber. NetCon is less than 7
I have 6 years experience troubleshooting and programming AES radios and just want so share some information with you guys. This will cover radio model numbers 7788/7744 , 7706 and 7058. Explaining how NetCon works does get detailed so I broke it up into 8 parts. Make sure to scroll all the way to the bottom of this page to see the rest of the parts.
Following is a general explanation of how NetCon is calculated by an AES UL 864, Edition 9 compliant model Subscriber (7744F or 7788F).
Look at your routing table. What is the Level/Link Layer (LL) of the #1 ID in the list? Is its Signal Quality (SQ) = Good? How many IDs are in the list at the same LL as #1 with a Good SQ? Subtract that number from 7. That should be the NetCon based on that routing table. On Edition 9 compliant units, NetCon will not be lower than 5 even if there are three units at the same Level that are good.Generally, if the SQ is not good, then it is quite possible that the Level was incremented by 1 for the purpose of sorting lower in the list. Sorting is primarily done on the LL. If there are no Good SQ or all IDs have faults, then the NetCon will be 7.
With one ID at LL 1 and SQ = Good the Subscribers LL should be 2 with a NetCon of 6.With two IDs LL 1 and SQ = Good the Subscribers LL should be 2 with a NetCon of 5.With one IP-Link ID at LL 0 and SQ = Good and another IP-Link ID at LL 0 or 1 with SQ = Marginal the Subscribers LL should be 1 with a NetCon of 6.
With two IP-Link IDs at LL 0 and SQ = Good the Subscribers LL should be 1 with a NetCon of 5.
7788F/7744F Rev 1.64Z5 also considers other ID’s in a table listed at a higher Level if it’s NetCon
Bats aka devil birds are funny looking. Those little evil winged spawn of satan sleep upside down. They scare little kids. Why should we care about them ?Well bats are great for pest control. They are worth about 3 billion per year for the U.S agriculture. Bats are the only flying mammal in the world. They kinda look like a cute flying dog. I recently learned that bats eat mosquitoes !! I need to adopt some bats for our house. Now more than ever since everyone is freaking out about zika. Bats eat all kinds of other bugs too. Bats and bees both pollinate plants. They do all that work and don’t ask nothing in return.
Unfortunately just like bees bats are dying by the millions. The dreaded White nose syndrome has killed over 5.7 million bats since first discovered in 2006. This fungus grows on bats while they are hibernating and damages their wings. The fungus messes with the bats hibernation. Bats eat a certain amount of food to gain fat so they can sleep thru winter. The fungus wakes them up and bats start flying around and acting like they normally do in spring. Since it’s winter they can’t really eat much and waste their fat reserves and die.
The White nose syndrome can only spread by touch so efforts are being made by authorities to either ban entry into batcaves (sorry batman) and or people will have to decontaminate their clothing. There is no current treatment or cure but I hope they find one soon.
