Permissible Values for Message Length Fields

It has come to our attention that experimentation with complex and/or irrational values of message lengths fields have introduced various anomalies, particularly when the socket connection involves a 23 bit quantum computing module.

It has been requested that such experiments cease without prior approval of this working group.

An anomaly has been noted when making use of complex number representations in the "un-send length" field of a standard message.  This anomaly only occurs when the sending code is running on a PDP-6 provided by Digital Equipment Corporation and equipped with a 23 bit quantum memory module as provided by ARPA.

It is suggested that we suspend experiments with un-sending datagrams until such a time that this can be resolved or at least explained.

Yes, you can send and receive vaid AFDX traffic (even the Boeing variant) over a standard Ethernet port.

Yeah, I know -- this is both vague and awfully specialized.  But for the two other people in the world who need to know this, the answer is "yes".

Solved a major problem with some C coding this morning. Coders will get this. Everyone else can feel free to stop reading.

Now for the rant. I had put a flag in the code to toggle a particular state. I wanted it off, so I sent it to zero. Was getting all kinds of bugs in the code and finally figured out that it seemed like the state was still on.

So, digging into the API that I'm using, I saw the following in one of their headers:

#define API_YES 0
#define API_NO 1

And I have just run out of expletives.

I might get sued if i named the popular software package that I saw that in.

...Not so, says Donald D. Hoffman, a professor of cognitive science at the University of California, Irvine. Hoffman has spent the past three decades studying perception, artificial intelligence, evolutionary game theory and the brain, and his conclusion is a dramatic one: The world presented to us by our perceptions is nothing like reality. What’s more, he says, we have evolution itself to thank for this magnificent illusion, as it maximizes evolutionary fitness by driving truth to extinction:

Pre-Connection Protocol

Building off of the anomaly as noted in RFC #26, it has been determined that it is possible to initiate a connection request via the Initial Connection Protocol (ICP) first described in RFC #66, using a similar complex numbering schema.

This would apparently indicate that the initiator of the connection (described as "server socket #1") is requesting that the connection be made at a previous point in time.  Is this what was intended by the protocol?

Negative Length Messages

In an effort to codify a mechanism for the retraction of messages, I suggest that we implement a negative-length message in the following format:

leader: 32 bits
marking: 32 bits
checksum: 16 bits
length: 16 bits
data: unused

Length shall be specified as the one's compliment of the length of the message to "un-send".  Other identifiers shall be specified as equal to those of the previous message.

Just going to have some fun with the un-issued RFC numbers.  :)

Okay establishment, you can probably succeed in shutting down the Sanders bid for the white house. And you can convince a lot of people that the cause of all of their problems are those different-colored people from other countries. And you can say that police misconduct and mass surveillance is for the greater good. And you can claim that the reason why people are poor and hungry is because they don't work hard enough.

You can do that, because you have the power to do so.

But you know what? You're going to lose. Not just because the people are going to win in the end. Not just because love triumphs over hate. And not just because you can't put the genie back in the bottle.

But because you are, right now, dying. And every tyrant eventually falls. Every. Single. One.

A "different colored"  person from another country - now a US Permanent Resident -
agrees with you.

I guess I'm supposed to put something here that is both clever and insightful and designed to entice people to get to know me.  But I won't.  Ha!

Every-other-day-ish I post something of relevance to me.  Probably artsy, or science-y or nerdy or something to do with whatever personal drama is in my live as I make a transition from extreme introvert to god-only-knows.  So just read the posts, k?
