Explanation of the BMDL Modeler
The BMDL Feature Modeler is a tool to describe Business Models through a combination of the Business Model Canvas (BMC) and a Software Product Line (SPL). We call this concept Business Model Decision Line (BMDL), where each feature describes a single business model decision. Features can be ordered in hierarchies and marked as mandatory or optional for the business models. Moreover, there can be Or (at least one sub-feature is selected) and Alternate (exactly one sub-feature is selected) relationships between a parent and a child feature. To refine the business models, cross-tree constraints for requiring and excluding dependencies can be made.
The current state of the tool allows the creation of feature models and the deriving of business models. New business model decisions of single business models are synchronized with the corresponding feature model to ensure consistency. Moreover, the conformance of business models can be checked with the feature model and occurring conformance errors are explained.
Execution Steps
Information about the execution steps:
- Create Feature Model: In the first step, the business developer has to create a feature model with all business model decisions. To support the conformance checking process, he can define mandatory and optional features and create dependencies (requires, excludes) between the features.
- Derive Business Models: In the second step, the business developer can derive a different business model from the feature model. Here, he can use the existing features from the feature model or add new business model decisions. These new feature model decisions will be added to the feature model to save consistency.
- Check Conformance: In the third step, the business developer can check the conformance between the feature model and the business model. Conformance errors will be explained to support the resolution.

Hi,
You can model this using set-constraints. Given are variables x', x,
and epsilon. Using a temporary set-variable S, add the following
constraints
rel(this, SOT_DUNION, [x,epsilon], S)
rel(this, S, SRT_SUP, x')
The first will make S be the union of the (disjoint) domains of x and
epsilon. The second makes sure that x' is a member of that set.
If you are concerned with efficieny, then you could add a custom
propagator for this constraint.
Cheers,
Mikael

DDSP
lets you combine the interpretable structure of classical DSP elements
(such as filters, oscillators, reverberation, etc.) with the expressivity
of deep learning
To start, you first have to initialize
SPICE so that you can use
SPICE to extract pitches from your audio.
const spice = new mm.SPICE(); await spice.initialize();
Extract Audio Features
spice.getAudioFeatures(audioBuffer)
Upload an audio file and call the `getAudioFeatures` method to get audio
features from your input audio.
Synthesize
To start synthesizing your audio, initialize mm.DDSP making sure to pass
in the URL of your own model or use one of our
4 models
(look for DDSP models).
const ddsp = new mm.DDSP(checkpointUrl);
ddsp.synthesize(audioFeatures)


1"> Invalid Policies Invalid Policy.
Policy is invalid because it was enabled but gets disconnected from the repo due to syntax error in the service template or deletion in the repo. If the policy becomes valid again from the repo, it will automatically re-enabled. You can also delete the invalid policies if they are no longer needed.

[telegram] <Ming 明> I mean the exchange section on coinomi not show barterdex
[telegram] <emman_utrum> I'm saying that since the beginning, but it is not as easy as it sounds. (re @mo7881: Think we need a hyperdex mobile wallet, with swaps done on the wallet)
[telegram] <mo7881> Some sort of komodo multi wallet like coinomi
[telegram] <mo7881> Then cut out 3rd party exchanges - do all the transfers with atomic swaps
[telegram] <Constantini21> I think that too (re @mo7881: Think we need a hyperdex mobile wallet, with swaps done on the wallet)
[telegram] <Constantini21> But coinomi doesn't support hyperDex (re @emman_utrum: )
[telegram] <Ming 明> that my point (re @Constantini21: But coinomi doesn't support hyperDex)
[telegram] <Acura360> Hyperdex is decentralized , Shapeshift and all the others are centralized (re @mo7881: Think we need a hyperdex mobile wallet, with swaps done on the wallet)
[telegram] <emman_utrum> The problem with atomic swaps is reputation. You need to trust your counterparty to some extent if you want to sacrifice your time (and potentially some money) doing the swap, and you need to care about your reputation if you're going to do that.
(edited)
[telegram] <Acura360> Centralized Exchanges have restrictions, AML Policy etc..
[telegram] <emman_utrum> Crypto social networks like Utrum are the solution, imo, to the reputation problem on atomic swaps.
[telegram] <Ming 明> i think kmd with mobile app exchange will make prople more easier to access to crypto and KMD
[telegram] <Ming 明> mass adoption will faster

[telegram] <Ming 明> (re @emman_utrum: Oh, huge Komodo community in Vietnam!)
[telegram] <emman_utrum> And yeah, what you say is true. Mobile is the only way to reach the masses.
[telegram] <Ming 明> another matter is public media saying bad about crypto - they prefer crypto as virtual money lol
[telegram] <Ming 明> not real life money
[telegram] <emman_utrum> So, according to what you say, Ming 明 , we, crypto people, have many challenges ahead.
One of them is making it easy to understand.
Another one is making it truly decentralized.
And the last one is making real life use of it.
I think I'm learning from you today!
[telegram] <JamPhish> Admin - I have a question concerning Komodo Censorship. Lets say for example, a market application is built on Komodo to sell Black Market Goods & Services . . . What means, if any, does the Community have to quickly & easily shut this market down?? (re @Hermes08: https://komodoplatform.com/komodo-wallets/)

 Censorship is an illusion for the masses. (re @JamPhish: Admin - I have a question concerning Komodo Censorship.

[telegram] <emman_utrum> Welcome to the internet.
[telegram] <macgy> yes (re @unknown: The KMD reward. The more KMD I hold in Agama, the more rewards I earn?)
[telegram] <JamPhish> Uuhh - that's what we call a cop out. I'm not debating whether or not the Black Market will continue in other ways - I'm speaking as an Investor in Komodo Value. If the platform is hosting Unwanted or Immoral Activities - its value to MOST of the world will be zero (re @emman_utrum: You can't censor anything actually. Censorship is an illusion for the masses.)
[telegram] <JamPhish> So again, my valid question - Is there a means of voting to remove Dapps? (re @JamPhish: Uuhh - that's what we call a cop out. I'm not debating whether or not the Black Market will continue in other ways - I'm speaking as an Investor in Komodo Value. If the platform is hosting Unwanted or Immoral Activities - its value to MOST of the world will be zero)
[telegram] <emman_utrum> Like Monero?
I think it's actually the opposite. Privacy capabilities increase the volume, interest from the public and price. (re @JamPhish: Uuhh - that's what we call a cop out. I'm not debating whether or not the Black Market will continue in other ways - I'm speaking as an Investor in Komodo Value. If the platform is hosting Unwanted or Immoral Activities - its value to MOST of the world will be zero)
[telegram] <emman_utrum> Huh... if there were a way, it wouldn't be truly decentralized. (re @JamPhish: So again, my valid question - Is there a means of voting to remove Dapps?)
[telegram] <JamPhish> Just because something is Decentralized, does not mean the Community has Zero Say.
Wow!
Fiat is backed by Governments . . .
Crypto is backed by Communities . . .
If the Community backing the Crypto is POWERLESS to affect that Crypto - the value to most of the WORLD IS ZERO
Obviously, the value toward the illegal World would be greater (re @emman_utrum: Huh... if there were a way, it wouldn't be truly decentralized.)
[telegram] <JamPhish> So - I believe you answered my question here - Komodo Community does not have the power to Regulate itself.
Does the Body regulate itself, clean itself up?? Yes - its called an immune system
[telegram] <emman_utrum> You can create a decentralized network that can vote on how to curate the data. But you cannot prevent the data from exist and be public on the internet. Once it is broadcast, it exists forever.
This is how the internet works in general, and blockchain in particular. (re @JamPhish: Just because something is Decentralized, does not mean the Community has Zero Say.

[telegram] <emman_utrum> I'm not talking about storage, I mean, literally public. (re @JamPhish: All Data is stored somewhere bro)
[telegram] <emman_utrum> If you really want to find some data, you will find it. This is specially true when we talk about blockchain.
[telegram] <JamPhish> Are you saying that a Blockchain can never be destroyed (re @emman_utrum: If you really want to find some data, you will find it. This is specially true when we talk about blockchain.)
[telegram] <emman_utrum> As long as there is interest in it, it will survive. Even if it dies, it can be reactivated at any moment. (re @JamPhish: Are you saying that a Blockchain can never be destroyed)
[telegram] <JamPhish> Or that a sidechain cannot be divorced from the main chain
[telegram] <emman_utrum> people interested in it could continue on their own fork. (re @JamPhish: Or that a sidechain cannot be divorced from the main chain)

[telegram] <JamPhish> I'm talking about Valuations . . . (re @emman_utrum: people interested in it could continue on their own fork.)
[telegram] <JamPhish> Some platforms like Eth are Non-Vetted

[telegram] <Crypto> Can we be honest? Komodo together with 99% of cryptos are shitcoin and will end to zero. New coins come , always pump and dumps...only bitcoin will survive

[telegram] <emman_utrum> Thanks to crypto-conditions Komodo is gonna have tokens.You can have your own NEO, if you want, and make it non-privacy capable, again, if you want.
That does not prevent people not agreeing with you, to just fork it, or launch their own version. (re @JamPhish: Some platforms like Neo are vetted)
[telegram] <Crypto> Ok tell me! (re @JamPhish: I can list about 10 reasons why Bitcoin will lose Market Dominence in the end)
[telegram] <Paulo_brificado>
[telegram] <emman_utrum> Bottom line is: NEO needs to be vetted, because it is monolithic.
Komodo is modular, and therefore, truly free. You can really do whatever you want with it.
(edited)
[telegram] <emman_utrum> Including, launching your own NEO platform! (This just blows my mind)
[telegram] <JamPhish> Bitcoin as a Currency has failed. The Governments and Enterprises are calling it a Comodity. For that, it will be treated as such. Bitcoin has too large a Market Cap currently for Private Investors to really move it. We will see Wall Street eventually rule Bitcoin by issuing BTC to Oil, BTC to Gold, BTC to Wheat, BTC to Uranium . . . it will become a globally accepted store of value - that's it.
Lightning Network only handles 2% of transactions and ONLY Functions in a Non-Hostile Environment. Also, Lightning relies on TRUSTED Master Nodes who act as a care taker of funds - legally - this would have to be a trusted 3rd Party and do a KYC for each user. In addition, Lightning Requires Sender / Receiver to always be online for transactions to go thru - this is very limiting.  Also, Lightning's method of account is essentially a digital fractional reserve banking system . . . we already have fractional reserve banking - this is the main reason peeps went toward crypto (re @Crypto: Ok tell me!)
[telegram] <JamPhish> Not to mention, Bitcoin Network is currently eating enough energy to power Ireland
[telegram] <JamPhish> In addition - where are the BTC DEVS??? The best DEVS are NoT with BTC
[telegram] <JamPhish> I think that, Wall Street will Use BTC as a store of value. People who have retirement funds will use BTC as a small hedge against traditional markets
[telegram] <JamPhish> But as far as using BTC to buy a cup of coffee - the ONLY people who want to use Bitcoin to buy a coffee would be a whale who owns SO MUCH, they dare not dump it and crash the price
[telegram] <Ming 明> along with small limited supply - it cant be a currency. (re @JamPhish: Bitcoin as a Currency has failed. The Governments and Enterprises are calling it a Comodity.

[telegram] <JamPhish> Also, Bitcoin code is bad ass
[telegram] <JamPhish> I'm not trying to be a downer - A realist - Augur has an Assassination Market up n going - its going to kill its value / price
[telegram] <JamPhish> I want to invest in something that can be paraded in tront of the public - that has a chance at main stream adoption
[telegram] <JamPhish> I'm just being real, thats all
[telegram] <JamPhish> Also, stable Coins are coming which will replace the Currency aspect. Community Backed Cryptos are Investment Vechicles (re @Ming 明: along with small limited supply - it cant be a currency.)
[telegram] <emman_utrum> Big whales are humans. And as such, they have a centralized mindset. It's easier to digest. They think that BTC is the center.
[telegram] <JamPhish> There is a bright future for Community Backed Cryptos
Especially, if an already existing global Community . . . approves of a specific crypto
[telegram] <JamPhish> Take Stellar & Islam for example
[telegram] <JamPhish> And I'll never buy Stellar Lumens, but its going to go up
[telegram] <JamPhish> Okay, maybe just to dump it - I'd buy
[telegram] <JamPhish> The common goal of making money is not enough to secure a Community for Generations - there must be another ideological glue (re @emman_utrum: Big whales are humans. And as such, they have a centralized mindset. It's easier to digest. They think that BTC is the center.)
[telegram] <JamPhish> Anyways - thanks Guys!!!
[telegram] <JamPhish> I'm still an Investor in Komodo

Produces power spectral density estimates through iterative refinement of the optimal number of sine-tapers at each frequency. This optimization procedure is based on the method of Riedel and Sidorenko (1995), which minimizes the Mean Square Error (sum of variance and bias) at each frequency, but modified for computational stability.

It was a Friday night the mindset was neutral. My friend T called me and asked if I wanted to dig in to my stash of AMT =/. i couldn’t resist. He later came and picked me up. We ran in to some girls that live in my neighborhood lets call them S and D. They wanted to go clubbing in Chicago (Mardi Gras party). We decided to go and take the AMT to see how it is.
We dose at around 6pm. then we call S and D to come and pick us up. I purchase some Marijuana (mid grade) to smoke on the drive down.
T + 1 hrs
T and I have to walk about a mile to a popular fast food joint. we start to come up but effects aren't noticeable.
T + 1.5 hrs
The girls finally show up and we start heading to Chicago. Once we get on the interstate we roll up a Blunt (about 1.7 grams) me D and T smoke it. This is when the effects are noticeable. T and I confirm that were tripping. Theirs no way we could drive on this dose. The lights from the card going past and going along with us have trails about 1 yard long. Music sounds nice and T and I are excited about the club because their are some good DJ's playing tonight. We both don't Puke or have nausea.
 We settle in and the night begins.
T + 3 hrs
T and I are now 'TRIPPPING BALLS' S and D want us to dance so we go out to the floor and give it a go. we dance for about 30 minutes and all I remember is the lights and people looking at me funny. I couldn’t really dance well on this dosage.
T + 4 hrs
T and I decide to sit and watch the ladies dance since it is Mardi Gras =). We both are getting great Visuals and fell great.
T + 5 hrs
D and S are party poopers and want to leave. We almost go to a kegger but decide to go home.  We roll up another blunt and we peak again. Nothing worth noting happened though out the rest of the night.
We finally fell asleep at T + 10 hours.
It was a enjoyable night, but I wouldn’t take this high of a dose at a Dance Club ever again. Maybe I will try 50mg’s just as stimuli. I had nausea at times and the visuals were intense at times. i smoked marijuana to ease nausea at around T + .5-1 hrs.

Request for Comments: not an RFC Category: Standards Track |
Alex Russell Greg Wilkins David Davis Mark Nesbitt |
This document specifies a protocol for the Internet community, and requests
discussion and suggestions for improvement.
This memo is written in the style and spirit of an IETF RFC but is not,
as of yet, an official IETF RFC.
Distribution of this memo is unlimited. This memo is written in UK English.
Copyright © The Dojo Foundation (2007). All Rights Reserved
Bayeux is a protocol for transporting asynchronous messages (primarily over HTTP), with low latency between a web server and web clients.
The primary purpose of Bayeux is to support responsive bidirectional interactions between web clients, for example using using AJAX, and the web server.
Bayeux is a protocol for transporting asynchronous messages (primarily over HTTP), with low latency between a web server and a web client. The messages are routed via named channels and can be delivered:
By default, publish subscribe routing semantics are applied to the channels.
Delivery of asynchronous messages from the server to a web client is often described as server-push.
The combination of server push techniques with an Ajax web application has been called Comet.
CometD is a project by the Dojo Foundation to provide multiple implementation of the Bayeux protocol
in several programming languages.
Bayeux seeks to reduce the complexity of developing Comet web applications by allowing implementors to more easily interoperate, to solve common message distribution and routing problems, and to provide mechanisms for incremental improvements and extensions.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC2119. An implementation is not compliant if it fails to satisfy one or more of the MUST or REQUIRED level requirements for the protocols it implements. An implementation that satisfies all the MUST or REQUIRED level and all the SHOULD level requirements for its protocols is said to be "unconditionally compliant"; one that satisfies all the MUST level requirements but not all the SHOULD level requirements for its protocols is said to be "conditionally compliant."
This specification uses a number of terms to refer to the roles played by participants in, and objects of, Bayeux communication:
The HTTP protocol is a request/response protocol. A client sends a request to the server in the form of a request method, URI, and protocol version, followed by a MIME-like message containing request modifiers, client information, and optional body content over a connection with a server. The server responds with a status line, including the message's protocol version and a success or error code, followed by a MIME-like message containing server information, entity metainformation, and possible entity-body content.
The server may not initiate a connection with a client nor send an unrequested response to the client, thus asynchronous events cannot be delivered from server to client unless a previously issued request exists. In order to allow two way asynchronous communication, Bayeux supports the use of multiple HTTP connections between a client and server, so that previously issued requests are available to transport server to client messages.
The recommendation of section 8.1.4 of RFC 2616 is that a single client SHOULD NOT maintain more than 2 connection with any server, thus the Bayeux protocol MUST NOT require any more than 2 HTTP requests to be simultaneously handled by a server in order to handle all application (Bayeux based or otherwise) requests from a client.
While HTTP is the predominant transport protocol used on the internet, it is not intended that it will be the only transport for Bayeux. Other transports that support a request/response paradigm may be used. However this document assumes HTTP for reasons of clarity. When non-HTTP connection-level transport mechanisms are employed, conforming Bayeux servers and clients MUST still conform to the semantics of the JSON encoded messages outlined in this document.
Several of the "transport types" described in this document are distinguished
primarily by how they wrap messages for delivery over HTTP and the sequence
and content of the HTTP connections initiated by clients. While this may seem
like a set of implementation concerns to observant readers, the difficulties of
creating interoperable implementations without specifying these semantics fully
is a primary motivation for the development of this specification.
Were the deployed universe of servers and clients more flexible, it may not
have been necessary to develop Bayeux.
Regardless, care has been taken in the development of this specification to ensure that future clients and servers which implement differing connection-level strategies and encodings may still evolve and continue to be conforming Bayeux implementations so long as they implement the JSON-based public/subscribe semantics outlined herein.
The rest of this document speaks as though HTTP will be used for message transport.
Bayeux clients implemented in JavaScript that run within the security
framework of a browser MUST adhere to the restrictions imposed
by the browser, such as the same origin policy
or the CORS specification,
or the threading model.
These restrictions are normally enforced by the browser itself, but nonetheless
the client implementation must be aware of these restrictions and adhere to them.
Bayeux clients implemented in JavaScript but not running within a browser MAY relax the restrictions imposed by browsers.
A Bayeux event is sent from the client to the server via a HTTP request initiated by a client and transmitted to the origin server via a chain of zero or more intermediaries (proxy, gateway or tunnel):
BC ---------- U ---------- P ------------ O ---------- BS | --M0(E)--> | | | | | | ---HTTP request(M0(E))--> | | | | | | --M0(E)--> | | | | | <---M1---- | | | <---HTTP response(M1)---- | | | <---M1--- | | | | | | | | |
The figure above represents a Bayeux event E encapsulated in a Bayeux message M0 being sent from a Bayeux client BC to a Bayeux server BS via a HTTP request transmitted from a User Agent U to to an Origin server O via a proxy P. The HTTP response contains another Bayeux message M1 that will at least contain the protocol response to M0, but may contain other Bayeux events initiated on the server or on other clients.
A Bayeux event is sent from the server to the client via a HTTP response to a HTTP request sent in anticipation by a client and transmitted to an origin server via a chain of zero or more intermediaries (proxy, gateway or tunnel):
BC ---------- U ---------- P ------------ O ---------- BS | ---M0---> | | | | | | --- HTTP request(M0) ---> | | | | | | ----M0---> | ~ ~ ~ ~ ~ wait | | | | <--M1(E)-- | | | <--HTTP response(M1(E))-- | | | <--M1(E)-- | | | | ~ ~ ~ ~ ~
The figure above represents a Bayeux message M0 being sent from a Bayeux client BC to a Bayeux server BS via a HTTP request transmitted from a User Agent U to to an Origin server O via a proxy P. The message M0 is sent in anticipation of a Bayeux event to be delivered from server to client and the Bayeux server waits for such an event before sending a response. A Bayeux event E is shown being delivered via Bayeux message M1 in the HTTP response. M1 may contain zero, one or more Bayeux events destined for the Bayeux client.
The transprt used to send events from the server to the client may terminate the HTTP response (which does not imply that the connection is closed) after delivery of M1 or use techniques to leave the HTTP response uncompleted and stream additional messages to the client.
Polling transports will always terminate the HTTP response after sending all available Bayeux messages.

Bayeux implementations MUST support a specific style of polling
transport called long polling (see sec 6.1).

In order to achieve bidirectional communication, a Bayeux client uses 2 HTTP connections (see section 1.4.1) to a Bayeux server so that both server to client and client to server messaging may occur asynchronously:
BC ---------- U ---------- P ------------ O ---------- BS | ---M0---> | | | | | | ------ req0(M0) --------> | | | | | | ----M0---> | ~ ~ ~ ~ ~ wait | --M1(E1)-> | | | | | | ----- req1(M1(E1))------> | | | | | | --M1(E1)-> | | | | | <---M2---- | | | <---- resp1(M2)---------- | | | <---M2--- | | | | ~ ~ ~ ~ ~ wait | | | | <-M3(E2)-- | | | <-----resp2(M3(E2))------ | | | <-M3(E2)-- | | | | | ---M4---> | | | | | | ------req3(M4)----------> | | | | | | ----M4---> | ~ ~ ~ ~ ~ wait
HTTP requests req0 and req1 are sent on different TCP/IP connections, so that the response to req1 may be sent before the response to req0. Implementations MUST control HTTP pipelining so that req1 does not get queued behind req0 and thus enforce an ordering of responses.
Bayeux connections are negotiated between client and server with handshake messages that allow the connection type, authentication and other parameters to be agreed upon between the client and the server.
BC ----------------------------------------- BS | ------------------ handshake request ---> | | <---- handshake response ---------------- | | -------------------- connect request ---> | ~ ~ wait | <------ connect response ---------------- |
Connection negotiation may be iterative and several handshake messages may be exchanged before a successful connection is obtained. Servers may also request connection renegotiation by sending an unsuccessful connect response with advice to reconnect with a handshake message.
BC ----------------------------------------- BS | ------------------ handshake request ---> | | <-- unsuccessful handshake response ----- | | ------------------ handshake request ---> | | <-- successful handshake response ------- | | -------------------- connect request ---> | ~ ~ wait | <------ connect response ---------------- | | -------------------- connect request ---> | | <---- unsucessful connect response ------ | | ------------------ handshake request ---> | | <-- successful handshake response ------- | | -------------------- connect request ---> | ~ ~ wait | <------ connect response ---------------- |
OPTIONALLY, messages can be sent without a prior handshake (see 5.1 Publish event messages).
BC ----------------------------------------- BS | ------------------- message request ----> | | <---- message response ------------------ |
This pattern is often useful when implementing non-browser clients for Bayeux servers. These clients often simply wish to address messages to other clients which the Bayeux server may be servicing, but do not wish to listen for events themselves.
-------------++------------+-------------+------------+------------ State/Event || handshake | Timeout | Successful | Disconnect || request | | connect | request || sent | | response | sent -------------++------------+-------------+----------- +------------ UNCONNECTED || CONNECTING | UNCONNECTED | | CONNECTING || | UNCONNECTED | CONNECTED | UNCONNECTED CONNECTED || | UNCONNECTED | | UNCONNECTED -------------++------------+-------------+------------+------------
The characters used for Bayeux names and identifiers are defined by the BNF definitions:
alpha = lowalpha | upalpha lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" | "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" | "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z" upalpha = "A" | "B" | "C" | "D" | "E" | "F" | "G" | "H" | "I" | "J" | "K" | "L" | "M" | "N" | "O" | "P" | "Q" | "R" | "S" | "T" | "U" | "V" | "W" | "X" | "Y" | "Z" digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" alphanum = alpha | digit mark = "-" | "_" | "!" | "~" | "(" | ")" | "$" | "@" string = *( alphanum | mark | " " | "/" | "*" | "." ) token = ( alphanum | mark ) *( alphanum | mark ) integer = digit *( digit )
Channels are identified by names that are styled as the absolute path component of a URI without parameters as defined by RFC2396.
channel_name = "/" channel_segments channel_segments = channel_segment *( "/" channel_segment ) channel_segment = token
The channel name consists of an initial "/" followed by an optional sequence of path segments separated by a single slash "/" character. Within a path segment, the character "/" is reserved.
Channel names commencing with "/meta/" are reserved for the Bayeux protocol.
Example non-meta channel names are:
A set of channels may be specified with a channel globbing pattern:
channel_pattern = *( "/" channel_segment ) "/" wild_card wild_card = "*" | "**"
The channel patterns support only trailing wildcards of either "*" to match a single segment or "**" to match multiple segments. Example channel patterns are:
The channels within the "/meta/" segment are the channels used by the Bayeux
protocol itself.
Local server-side Bayeux clients MAY, and remote Bayeux clients SHOULD NOT,
subscribe (see section 4.5) to meta channels.
Messages published to meta channels MUST NOT be distributed to remote clients
by Bayeux servers. A server side handler of a meta channel MAY publish response
messages that are delivered only to the client that sent the original request message.
If a message published to a meta channel contains an id field, then any
response messages delivered to the client MUST contain an id field with the
same value.
The channels within the "/service/" channel segment are special channels
designed to assist request/response style messaging.
Messages published to service channels are not distributed to any remote Bayeux clients.
Handlers of service channels MAY deliver response messages to the client that
published the request message. Servers SHOULD NOT record any subscriptions they
receive for service channels.
If a message published to a service channel contains an id field, then any
response messages SHOULD contain an id field with the same value or a value
derived from the request id.
Request/response operations are described in detail in section 9.
A protocol version is a integer followed by an optional "." separated sequence of alphanumeric elements:
version = integer *( "." version_element ) version_element = alphanum *( alphanum | "-" | "_" )
Versions are compared element by element, applying normal alphanumeric comparison to each element.
A client ID is an random, non predictable sequence of alpha numeric characters:
clientId = alphanum *( alphanum )
Client IDs are generated by the server and SHOULD be created with a strong random algorithm that contains at least 128 truly random bits. Servers MUST ensure that client IDs are unique and SHOULD attempt to avoid reuse of client IDs. Client IDs are encoded for delivery as strings.
Bayeux messages are JSON encoded objects that contain an unordered sequence of
name value pairs representing fields and values. Values may be a simple
strings, numbers, boolean values, or complex JSON encoded objects or arrays.
A Bayeux message MUST contain one and only one channel field which determines
the type of the message and the allowable fields.
All Bayeux messages SHOULD be encapsulated in a JSON encoded array so that multiple messages may be transported together. A Bayeux client or server MUST accept either array of messages and MAY accept a single message. The JSON encoded message or array of messages is itself often encapsulated in transport specific formatting and encodings. Below is an example Bayeux message in a JSON encoded array representing an event sent from a client to a server:
[ { "channel": "/some/name", "clientId": "83js73jsh29sjd92", "data": { "myapp" : "specific data", value: 100 } } ]
The channel message field MUST be included in every Bayeux message to specify the source or destination of the message. In a request, the channel specifies the destination of the message, and in a response it specifies the source of the message.
The version message field MUST be included in messages to/from the "/meta/handshake" channel to indicate the protocol version expected by the client/server.
The minimumVersion message field MAY be included in messages to/from the "/meta/handshake" channel to indicate the oldest protocol version that can be handled by the client/server.
The supportedConnectionTypes field is included in messages to/from the "/meta/handshake" channel to allow clients and servers to reveal the transports that are supported. The value is an array of strings, with each string representing a transport name. Defined connection types include:
All server and client implementations MUST support the "long-polling"
connection type and SHOULD support "callback-polling".
All other connection types are OPTIONAL.
The clientId message field uniquely identifies a client to the Bayeux server.
The clientId message field MUST be included in every message sent to the server
except for messages sent to the "/meta/handshake" channel and MAY be omitted in
a publish message (see section 5.1).
The clientId field MUST be returned in every message response except for a
failed handshake request and for a publish message response that was send without
clientId.
The advice field provides a way for servers to inform clients of their preferred mode of client operation so that in conjunction with server-enforced limits, Bayeux implementations can prevent resource exhaustion and inelegant failure modes.
The advice field is a JSON encoded object containing general and transport specific values that indicate modes of operation, timeouts and other potential transport specific parameters. Fields may occur either in the top level of a message or within a transport specific section.
Unless otherwise specified in sections 5 and 6, any Bayeux response message may contain an advice field. Advice received always superceeds any previous received advice.
An example advice field is:
"advice": { "reconnect": "retry", "interval": 1000, "callback-polling": { "reconnect": "handshake" } }
The reconnect advice field is a string that indicates how the client should act in the case of a failure to connect. Defined reconnect values are:
Any client that does not implement all defined values of reconnect MUST NOT automatically retry or handshake.
An integer representing the minimum period in milliseconds for a client to delay
subsequent requests to the /meta/connect channel.
A negative period indicates that the message should not be retried.
A client MUST implement interval support, but a client MAY exceed the interval provided by the server. A client SHOULD implement a backoff strategy to increase the interval if requests to the server fail without new advice being received from the server.
This is a boolean field, which if true indicates that the server has detected multiple Bayeux client instances running within the same HTTP client.
This is an array of strings field, which if present indicates a list of host names or IP addresses that MAY be used as alternate servers with which the client may connect. If a client receives advice to re-handshake and the current server is not included in a supplied hosts list, then the client SHOULD try the hosts in order until a successful connection is establish. Advice received during handshakes with hosts in the list supercedes any previously received advice.
The connectionType message field specifies the type of transport the client requires for communication. The connectionType message field MUST be included in request messages to the "/meta/connect" channel. Connection types are listed in section 3.4.
An id field MAY be included in any Bayeux message with an alpha numeric value:
id = alphanum *( alphanum )
Generation of IDs is implementation specific and may be provided by the application. Messages published to /meta/** and /service/** SHOULD have id fields that are unique within the the connection.
Messages sent in response to messages delivered to /meta/** channels MUST use the same message id as the request message.
Messages sent in response to messages delivered to /service/** channels SHOULD use the same message id as the request message or an id derived from the request message id.
The timestamp message field SHOULD be specified in the following ISO 8601 profile (all times SHOULD be sent in GMT time):
YYYY-MM-DDThh:mm:ss.ss
A timestamp message field is OPTIONAL in all Bayeux messages.
The data message field is an arbitrary JSON encoded object that contains event information. The data field MUST be included in publish messages, and a Bayeux server MUST include the data field in an event delivery message.
The connectionId field was used during development of the Bayeux protocol and its use is now deprecated.
The successful boolean message field is used to indicate success or failure and MUST be included in responses to the "/meta/handshake", "/meta/connect", "/meta/subscribe","/meta/unsubscribe", "/meta/disconnect", and publish channels.
The subscription message field specifies the channels the client wishes to subscribe to or unsubscribe from. The subscription message field MUST be included in requests and responses to/from the "/meta/subscribe" or "/meta/unsubscribe" channels.
The error message field is OPTIONAL in any Bayeux response.
The error message field MAY indicate the type of error that occurred when a
request returns with a false successful message. The error message field should
be sent as a string in the following format:
error = error_code ":" error_args ":" error_message | error_code ":" ":" error_message error_code = digit digit digit error_args = string *( "," string ) error_message = string
Example error strings are:
401::No client ID 402:xj3sjdsjdsjad:Unknown Client ID 403:xj3sjdsjdsjad,/foo/bar:Subscription denied 404:/foo/bar:Unknown Channel
An ext field MAY be included in any Bayeux message. Its value SHOULD be a JSON encoded object with top level names distinguished by implementation names (eg. "org.dojo.Bayeux.field").
The contents of ext may be arbitrary values that allow extensions to be negotiated and implemented between server and client implementations.
The json-comment-filtered ext field of the handshake message is deprecated.
A Bayeux client initiates a connection negotiation by sending a message to the
"/meta/handshake" channel.
For same domain connections, the handshake requests MUST be sent to the server
using the long-polling transport, while for cross domain connections the handshake
request MAY be sent with the long-polling transport and failing that with the
callback-polling transport.
A handshake request MUST contain the message fields:
A handshake request MAY contain the message fields:
A client SHOULD NOT send any other message in the request with a handshake message. A server MUST ignore any other message sent in the same request as a handshake message. An example handshake request is:
[ { "channel": "/meta/handshake", "version": "1.0", "minimumVersion": "1.0beta", "supportedConnectionTypes": ["long-polling", "callback-polling", "iframe"] } ]
A Bayeux server MUST respond to a handshake request with a handshake response message. How the handshake response is formatted depends on the transport that has been agreed between client and server.
A successful handshake response MUST contain the message fields:
A successful handshake response MAY contain the message fields:
An example successful handshake response is:
[ { "channel": "/meta/handshake", "version": "1.0", "minimumVersion": "1.0beta", "supportedConnectionTypes": ["long-polling","callback-polling"], "clientId": "Un1q31d3nt1f13r", "successful": true, "authSuccessful": true, "advice": { "reconnect": "retry" } } ]
An unsuccessful handshake response MUST contain the message fields:
An unsuccessful handshake response MAY contain the message fields:
An example unsuccessful handshake response is:
[ { "channel": "/meta/handshake", "version": "1.0", "minimumVersion": "1.0beta", "supportedConnectionTypes": ["long-polling","callback-polling"], "successful": false, "error": "Authentication failed", "advice": { "reconnect": "none" } } ]
For complex connection negotiations, multiple handshake messages may be exchanged between the Bayeux client and server. The handshake response will set the "successful" field to false until the handshake processs is complete. The advice and ext fields may be used to communicate additional information needed to complete the handshake process. An unsuccessful handshake response with reconnect advice of "handshake" is used to continue the connection negotiation. An unsuccessful handshake response with reconnect advice of "none" is used to terminate connection negotiations.
After a Bayeux client has discovered the server's capabilities with a handshake exchange, a connection is established by sending a message to the "/meta/connect" channel. This message may be transported over any of the transports indicated as supported by the server in the handshake response.
A connect request MUST contain the message fields:
A connect request MAY contain the message fields:
A client MAY send other messages in the same HTTP request with a connection message. A server MUST handle any other message sent in the same request as a connect message after the handling of the connect message is complete.
An example connect request is:
[ { "channel": "/meta/connect", "clientId": "Un1q31d3nt1f13r", "connectionType": "long-polling" } ]
A transport MUST maintain one and only one outstanding connect message. When a HTTP response that contains a /meta/connect response terminates, the client MUST wait at least the interval specified in the last received advice before following the advice to reestablish the connection
A Bayeux server MUST respond to a connect request with a connect response message over the same transport used for the request.
A Bayeux server MAY wait to respond until there are event messages available in the subscribed channels for the client that need to be delivered to the client.
A connect responses MUST contain the message fields:
A connect response MAY contain the message fields:
An example connect response is:
[ { "channel": "/meta/connect", "successful": true, "error": "", "clientId": "Un1q31d3nt1f13r", "timestamp": "12:00:00 1970", "advice": { "reconnect": "retry" } } ]
The client MUST maintain only a single outstanding connect message. If the server does not have a current outstanding connect and a connect is not received within a configured timeout, then the server SHOULD act as if a disconnect message has been received.
When a connected client wishes to cease operation it should send a request to the "/meta/disconnect" channel for the server to remove any client-related state. The server SHOULD release any waiting meta message handlers. Bayeux client applications should send a disconnect request when the user shuts down a browser window or leaves the current page. A Bayeux server SHOULD not rely solely on the client sending a disconnect message to remove client-related state information because a disconnect message might not be sent from the client or the disconnect request might not reach the server.
A disconnect request MUST contain the message fields:
A disconnect request MAY contain the message fields:
An example disconnect request is:
[ { "channel": "/meta/disconnect", "clientId": "Un1q31d3nt1f13r" } ]
A Bayeux server MUST respond to a disconnect request with a disconnect response.
A disconnect response MUST contain the message fields:
A disconnect response MAY contain the message fields:
An example disconnect response is:
[ { "channel": "/meta/disconnect", "clientId": "Un1q31d3nt1f13r", "successful": true } ]
A connected Bayeux client may send subscribe messages to register interest in a channel and to request that messages published to that channel are delivered to itself.
A subscribe request MUST contain the message fields:
A subscribe request MAY contain the message fields:
An example subscribe request is:
[ { "channel": "/meta/subscribe", "clientId": "Un1q31d3nt1f13r", "subscription": "/foo/**" } ]
A Bayeux server MUST respond to a subscribe request with a subscribe response message.
A Bayeux server MAY send event messages for the client in the same HTTP response as the subscribe response, including events for the channels just subscribed to.
A subscribe response MUST contain the message fields:
A subscribe response MAY contain the message fields:
An example successful subscribe response is:
[ { "channel": "/meta/subscribe", "clientId": "Un1q31d3nt1f13r", "subscription": "/foo/**", "successful": true, "error": "" } ]
An example failed subscribe response is:
[ { "channel": "/meta/subscribe", "clientId": "Un1q31d3nt1f13r", "subscription": "/bar/baz", "successful": false, "error": "403:/bar/baz:Permission Denied" } ]
A connected Bayeux client may send unsubscribe messages to cancel interest in a channel and to request that messages published to that channel are not delivered to itself.
An unsubscribe request MUST contain the message fields:
An unsubscribe request MAY contain the message fields:
An example unsubscribe request is:
[ { "channel": "/meta/unsubscribe", "clientId": "Un1q31d3nt1f13r", "subscription": "/foo/**" } ]
A Bayeux server MUST respond to a unsubscribe request with a unsubscribe response message.
A Bayeux server MAY send event messages for the client in the same HTTP response as the unsubscribe response, including events for the channels just unsubscribed to as long as the event was processed before the unsubscribe request.
An unsubscribe response MUST contain the message fields:
A unsubscribe response MAY contain the message fields:
An example unsubscribe response is:
[ { "channel": "/meta/unsubscribe", "clientId": "Un1q31d3nt1f13r", "subscription": "/foo/**", "successful": true, "error": "" } ]
Application events are published in event messages sent from a Bayeux client to a Bayeux server and are delivered in event messages sent from a Bayeux server to a Bayeux client.
A Bayeux client can publish events on a channel by sending event messages. An event message MAY be sent in new HTTP request or it MAY be sent in the same HTTP request as any message other than a handshake meta message.
A publish message MAY be sent from an unconnected client (that has not performed handshaking and thus does not have a client ID). It is OPTIONAL for a server to accept unconnected publish requests and they should apply server specific authentication and authorization before doing so.
A publish event message MUST contain the message fields:
A publish event message MAY contain the message fields:
An example event message is:
[ { "channel": "/some/channel", "clientId": "Un1q31d3nt1f13r", "data": "some application string or JSON encoded object", "id": "some unique message id" } ]
A Bayeux server MAY respond to a publish event message with a publish event acknowlegement.
A publish event message MUST contain the message fields:
A publish event response MAY contain the message fields:
An example event reponse message is:
[ { "channel": "/some/channel", "successful": true, "id": "some unique message id" } ]
Event messages MUST be delivered to clients if the client is subscribed to the channel of the event message.
Event messages MAY be sent to the client in the same HTTP response as any other message other than a meta handshake
response.
If a Bayeux server has multiple HTTP requests from the same client, the server SHOULD deliver all available messages
in the HTTP response that will be sent immediately in preference to waking a waiting connect meta message request.
Event message delivery MAY not acknowledged by the client.
A deliver event message MUST contain the message fields:
A deliver event response MAY contain the message fields:
An example event deliver message is:
[ { "channel": "/some/channel", "data": "some application string or JSON encoded object", "id": "some unique message id" } ]
"Long-polling" is a polling transport that attempts to minimize both latency in server-client message delivery, and the
processing/network resources required for the connection. In "traditional" polling, servers send and terminate responses to
requests immediately, even when there are no events to deliver, and worst-case latency is the polling delay between each
client request.
Long-polling server implementations attempt to hold open each request until there are events to deliver;
the goal is to always have a pending request available to use for delivering events as they occur, thereby minimizing
the latency in message delivery.
Increased server load and resource starvation are addressed by using the reconnect and
interval advice fields to throttle clients, which in the worst-case degenerate to traditional polling behaviour.
Messages SHOULD be sent to the server as the body of an application/json
HTTP POST request.
Alternatively, messages MAY be sent to the server as the 'message' parameter of a
application/x-www-form-urlencoded encoded POST request.
If sent as form encoded, the Bayeux messages are sent as the "message" parameter in one of
the following forms as:
Messages SHOULD be sent to the client as unencapsulated body content of a HTTP POST response with content type application/json.
A long-polling response message may contain an advice field containing transport-specific
fields to indicate the mode of operation of the transport.
For the long-polling transport, the advice field MAY contain the following fields:
Messages SHOULD be sent to the server as the 'message' parameter of a url encoded HTTP GET request.
Responses are sent wrapped in a JavaScript callback in order to facilitate delivery.
As specified by the JSON-P pseudo-protocol, the name of the callback to be triggered
is passed to the server via the jsonp HTTP GET parameter.
In the absence of such a parameter, the name of the callback defaults to jsonpcallback.
The called function will be passed a JSON encoded array of Bayeux messages.
A callback-polling response message may contain an advice field containing transport-specific
fields to indicate the mode of operation of the transport.
For the callback-polling transport, the advice field MAY contain the following fields:
Bayeux may be used with:
For Bayeux authentication, no algorithm is specified for generating or validating security credentials or token. This version of the protocol only defines that the ext field may be used to exchange authentication challenges, credentials, and tokens and that the advice field may be used to control multiple iterations of the exchange.
The connection negotiation mechanism may be used to negotiate authentication or request re-authentication.
The Ajax hijacking vulnerability is when an attacking web site uses a script tag to execute JSON encoded content obtained from an Ajax server. The Bayeux protocol is not vulnerable to this style of attack when cookies are not used for authentication and a valid client ID is needed before private client data is returned. The use of POST by some transports further protects against this style of attack.
Current HTTP client implementations are RECOMMENDED to allow only 2
connections between a client and a server.
This presents a problem when
multiple instances of the Bayeux client are operating in multiple tabs or
windows of the same browser instance. The 2 connection limit can be consumed
by outstanding connect meta messages from each tab or window and thus prevent
other messages from being delivered in a timely fashion.
It is RECOMMENDED that Bayeux server implementations use the cookie "BAYEUX_BROWSER" to identify a HTTP client and to thus detect multiple Bayeux clients running within the same HTTP client. Once detected, the server SHOULD not wait for messages in connect and SHOULD use the advice interval mechanism to establish traditional polling.
It is RECOMMENDED that Bayeux client implementations use client side persistence or cookies to detect multiple intances of Bayeux clients running within the same HTTP client. Once detected, the user MAY be offered the option to disconnect all but one of the clients. It MAY be possible for client implementations to use client side persistence to share a Bayeux client instance.
The publish/subscribe paradigm that is directly supported by the Bayeux protocol is difficult to use to efficiently implement the request/response paradigm between a client and a server. The /service/** channel space has been designated as a special channel space to allow efficient transport of application request and responses over Bayeux channels. Messages published to service channels are not distributed to other Bayeux clients so these channels can be used for private requests between a Bayeux client and a Bayeux server.
A trivial example would be an echo service, that sent any message received from a client back to that client unaltered. Bayeux clients would subscribe the the /service/echo channel, but the Bayeux server would not need to record this subscription. When a client publishes a message to the /service/echo channel, it will be delivered only to server-side subscribers (in an implementation depedent fashion). The server side subscriber for the echo service would handle each message received by publishing a response directly to the client regardless of any subscription. As the client has subscribed to /service/echo, the response message will be routed correctly within the client to the appropriate subscription handler.

Alfie Perkins, 19, was left with a fractured skull when a car allegedly failed to stop at a red light while driving at speed.
He shared photographs of his bloodied face and scarred body following the incident on November 2.
Writing on Twitter, Perkins said: ‘Life comes at you nearly as fast as speeding cars that don’t stop on red lights do’.
He added: ‘Didn’t think it was possible for me to get any uglier but here we are with my face drooping to the right and the left side of it not working, you not reckon it’s time I caught a break’.
However, he denied suggestions the incident was ‘karma’ for trolling the football star after that was suggested by another twitter user.
Perkins replied: ‘Leg it bruv, karma for laughing at somebody being dead is not fracturing your skull in two places hahaha’.

Earlier this year, Perkins downed nine pints of lager before watching Birmingham City vs Aston Villa derby
He then sent Grealish, who scored the winning goal, three horrific messages about his baby brother Keelan.
On one tweet, Perkins included a picture of Keelan’s gravestone.
He tweeted: ‘He may have scored but will never bring his dead brother back and that brings me more satisfaction than anything else ever could.’
Another tweet said: ‘Grealish went down quicker than his brother got lowered into the grave. Where’s your brother gone? Come on!’
Keelan fell victim to cot death in April 2000, aged just nine months old. Grealish was aged four at the time.
Perkins, an accountancy and finance student, was ordered to pay a fine and was seen smirking outside of court following the trial.
When questioned about his smiles outside of court, Perkins tweeted: ‘I regret all of it but she says this like nobody would be smiling after being faced with the prospect of prison and the end result being only having to pay £350. Wallop.’

THE LAST SEDUCTION A film review by Jules N. Binoculas Copyright 1994 Jules N. Binoculas
If you're trying to make a name for yourself as a young-writer-director who loves to modernize 40's-and-50's-style neo-Hellenic-film-noir-pseudo-tragedies--have fun. But you *must* do one thing above all else: have your characters understand that anyone they meet who is beautiful--will be trying to f*** with them.
 If your characters are lucky enough to suspect trouble, and they find themselves in moral quicksand--helpless to stop it--you're in business.
But, remember: once you let us meet your sensation-loving people, you must guide us inside their psyches with gentle authority, and induce us to promise to love, cherish and stick with them to the rancid, bitter end. Otherwise, you--the director--lose your customers in a crowded, derivative, intellectual conceit--a seedy, aimless, masquerade of your own perverse creation.
 That's the easy part. The rest is more obvious.
If director, JOHN DAHL wants to make answering-machine-era adultery and murder seem fresh and promising by exposing his own jaundiced fascination with eternally predatory, insatiably manipulative Medusas, who are we to complain? If he can pull it off....
 An enviable lifestyle? You make the call.
On the surface, it's a harmlessly, entertaining masturbatory extrapolation of the post-50's "PLAYBOY Philosophy," and, if plotted properly, could yield a vigorous, lusty suspense-thriller--kind of like a 90's James M. Cain story of yuppie hypocrites who get their kicks murdering private detectives in sports-utility vehicles.
But, to his discredit, Mr. Dahl is so enamored with his own machinations of the "sex-and-greed-to-a-dead-end-lead" story angles, that he forgets that the most important element in a good thriller is not the "how," but the "why."
(And borrowed-twists from THE CRYING GAME, DOUBLE INDEMNITY, and BODY HEAT don't help endear us to his cerebral crusade.)
Normally, in these types of twisty, dime-store plot-gymnastics, the bewitching woman is a seemingly coincidentally placed, sensually spidery "antagonist", who draws a self-doubting, emasculated male into her hedonistic web of predatory plans. But, anxious to outdo everyone who has ever tried the genre, Mr. Dahl wants to swing both ways and make her both the opaque seductress and the carnivorous, abused, on-the-lam heroine (and corrupt anti-heroine). Where can an over-stimulated audience find some warmth and understanding? Not in this film.
The story uses so much calculation, it dilutes any developing audience-allegiances--only to drive us all nowhere but back to where we started.
Dahl kick-starts his needlessly dizzying story by reving the sensual, testicle-slicing ambition of Linda Fiorentino's Brigid (rhyming with "frigid,"--but that's where the resemblance ends).
 Just another ordinary, genre-driven, domestically dysfunctional screen-squabble, updated for current social mores.
For a film reeking of ruthlessness, ironically, it's Dahl himself who commits the most unpardonable sin--allowing us to be confused by people's half-explained pasts, and fuzzy future plans. He throws away early scenes which could've helped us understand whether she's a generic sociopath, oxymoronically dominant and insecure, terminally impulsive, or just nakedly copying Hitchcock's PSYCHO, in her vain escape from New York for Chicago with $700,000 in laundered bills.
Yet, despite the schizoid character development, the film is more than marginally likable, mostly because it doesn't try to "get-heavy" with cumbersome personality explications. Unfortunately, neither does it try to "get serious" and make us care about its throbbing, but philosophically stagnant, souls.
The attempt at a deadpan tone keeps the plot afloat for a while--only to submerge it with convoluted conceits--jammed into a designer pair of black panties with nothing inside but naked schemes.
RATING: 80/100
Recommendation: If you're desperate for lusty, vicious, gonad-eating women--then treat yourself to the genuine articles: DOUBLE INDEMNITY, an X-rated wall-to-wall-flesh-fest, and a campy, Russ Meyer bosomaniacal extravaganza.
If all else fails, you can sit it out and pray that Mr. Dahl reaches narrative puberty before THE LAST SEDUCTION becomes his last attempt at noirish-homage.

TERMINAL VELOCITY A film review by James Berardinelli Copyright 1994 James Berardinelli
Rating (0 to 10): 3.0
Date Released: 9/23/94 Running Length: 1:47 Rated: PG-13 (Violence, language)
Starring: Charlie Sheen, Nastassja Kinski, James Gandolfini, Christopher McDonald, Melvin Van Peebles Director: Deran Sarafian Producers: Scott Kroopf and Tom Engelman Screenplay: David Twohy Cinematography: Oliver Wood Music: Joel McNeely Released by Hollywood Pictures
Eureka! Why didn't I think of it earlier? It's amazing how sometimes these things get past a person. To what am I referring? Why, TERMINAL VELOCITY, of course. For a moment, I almost thought this was a serious movie. But, upon careful consideration, I've come to a different conclusion.  The only problem is, I don't think the filmmakers share my view.
It is possible to enjoy TERMINAL VELOCITY once you realize how truly awful a film it is. In fact, it's only then when it becomes fun. In terms of laughs, there are moments of high mirth. The question is: how much of the humor is intentional? Sadly, given the way the film was put together, the answer is likely to be disappointing. Intent, however, does little to limit effect. Why else do people find PLAN NINE FROM OUTER SPACE so engaging? (No, TERMINAL VELOCITY is nowhere near that quality level.)
I have never admired Charlie Sheen as an action hero. He does the wise-cracking okay, and he's not bad in a fight, but there's one major asset he lacks: an accent. How can you take anyone serious in this sort of movie when they sound like they were born in this country? Even Steven Seagal has an accent of sorts ... it's called a monotone.
Ah, but then there's Nastassja Kinski, and she has the accent. Given the way she takes command, it becomes apparent who the real muscle in this movie is. Sheen is just along for the ride (so to speak)--a "male love interest." That doesn't really fit, though, because he gets top billing. Then along comes the scene with the freefalling car, and it all clicks into place. Sheen isn't the action hero or the token beefcake. He's the comic relief.
Then again, maybe not...
The plot takes preposterousness to new levels. I doubt even Forrest Gump would be able to suspend his disbelief enough to swallow what this movie has to offer, worm and all. It's about a former KGB agent named Chris Morrow (Kinski) who decides to go skydiving one afternoon. Her teacher, a guy with the unlikely appellation of Ditch Brodie (Sheen), is so intent on getting her into bed that he doesn't notice when she takes an unsupervised jump out of the plane. A few minutes later, she goes splat, and he's left nursing his guilt and facing a possible manslaughter charge. However, when he visits the dead girl's apartment, he learns that things may not be quite as they look.
The dialogue is as hard-boiled as it comes. These are the kinds of lines that once made dime-store novels so popular. And it's not just occasional. "Pack the bags--we're going on a guilt trip" happens to be my favorite, but there are lots more to choose from.
TERMINAL VELOCITY has an unfair advantage over many other bad movies: it's too raucous to put anyone to sleep. There are enough explosions, gun fights, and loud music to arouse the attention of even the most disinterested viewer. Laughably preposterous--yes; boring--no. It's an experience, all right--albeit one that most people can do without.

High Priest Orven:
Welcome to Aden Town, the heart of the kingdom. People speak of this place as the kingdom's cultural and religious center. If that is true, then it is also the apex of faith that all who serve Einhasad must preserve....
But true holiness can always be found in the ordinary, the everyday, the mundane. The prayer of a commoner may resonate more deeply with the mother of light than even the prayer of a high priest, so perhaps this place is not so different from other temples.

Syllabus
| Topic |
Description |
Organic Molecules
|
The first unit of the class. You will be introduced to what the Organic molecules are and what makes an Organic
Molecule (High energy C-C or C-H bonds). You will also learn the monomers of each orgainic molecule (Amino Acids
for Proteins, Glucose for Carbohydrates and Glycogen/Fatty Acids for Lipids) and generally this first unit is pretty
simple as it introduces you to what'll be needed for the next few units. Additionally you learn how to write conclusions
here as well.
|
Cellular Functions
|
This unit expands on the first unit. You will learn about Digestion and how Polymers are broken down into Monomers
as well as Biosynthesis and how monomers are recontructed for the needs of the body and in the case of plants, reconstructed
into other organic biomolecules. Cellular respiration and the breaking down of glucose for energy in the form of ATP will also
be taught here. Additionally you will learn about the phospholipid bilayer and how molecules diffuse into and out of a cell via
osmosis to achieve equilibrium. Modeling of Biosynthesis and digestion will better help understand the transition from
monomer to polymer.
|
DNA the 4th Biomolecule
|
This unit will introduce DNA, as well as DNA replication of cells known as Mitosis. There will be drawing activities to
teach the double helix, the nitrogenous bases Adenine, Thymine, Cytosine, and Guanine as well as RNA and its unique base
Uracil. Afterwards you will learn about proteins and enzymes and how DNA codes for proteins with the help of RNA.
|
Genetics and Inheritance
|
This unit will introduce Meiosis and how gametes came to be. You will utilize the Punnett Square in modeling what offsprings
will recieve what genetics from their parents and also learn about mutation in the process. Afterwards, you will learn about
the history of the Earth via the Geologic Clock and learn how evolution/natural selection over time caused certain orgainisms to
be how they currently are and how they've changed from their ancestors. The anole lizard activity will be the main focus at that
point in modeling evolution.
|
Ecosystems
|
This final unit will introduce where Carbon Pools are in an Ecoystem, (producers, consumers, decomposers, atmosphere) and what the
relationship between them is. A flash game called Sunny Meadows will be the focus at the start of the unit and after you learn about
how to trace carbon and energy in ecosystems and how big carbon pools are, there will be a presentation in groups. Also, finals will be
an oral presentation in front of the class of something you learned in the school year.

Big, important ideas can often be overlooked because of how boring they sound to the average listener. Remember SOPA and PIPA a few years back? In addition to obscure acronyms, they were also known as HR 3261 and Senate Bill 968, respectively. Or, if you want to get really descriptive, you can go by their long titles:
“To promote prosperity, creativity, entrepreneurship, and innovation by combating the theft of U.S. property, and for other purposes.” —H.R. 3261
and
Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011
Snore.
The truth of the matter is that no one would have paid attention to those two bills had it not been for the Internet. Reddit was the birthing ground of the Stop SOPA/PIPA protests, eventually gaining support from the Internet giants, Google, Facebook, Netflix, and others. The free sharing of ideas and strategy over the web allowed for the global public to stand up against dangerous legislation.
It’s been nearly four years, and the integrity of the Internet is at stake again.
Net Neutrality, in its simplest terms, means that anyone can create and share content equally across the Internet. No outside agency – be it company or individual – can limit how you transmit that information from one place to another. It’s how the Internet was designed, and how it’s been run, since the beginning. This principle is what allowed the SOPA and PIPA protests to be successful. It helped kickstart the Arab Spring (remember when Egypt turned the Internet off? That didn’t go so well.) and it’s been a major outlet for on-the-ground news through social media channels.
It also allows students and independent creators to have a level playing field with major corporations. This is why Net Neutrality matters to schools.
Internet Service Providers (ISPs) like Comcast and Verizon want to end regulation on the use of the Internet. The FCC used to have rules in place which regulated how ISPs could transmit data to customers. Long story short, Verizon sued the FCC, and the Supreme Court determined the regulations were outside the scope of the FCC. Now, we’re approaching the release of new regulations which have been influenced by millions upon millions of lobbying dollars on the FCC.
The new proposed rules would allow companies to create “fast lanes” of content which would be paid for by content providers like Netflix or YouTube. What are the stipulations, you ask? Those lanes must make “economic sense” to the ISPs. In other words, we’re racing for a tiered Internet if the FCC regulations are accepted and implemented.
But, it doesn’t make sense for companies to do that, so why would they?
Actually, they’ve already done it. The Oatmeal has a great post on what Comcast did to Netflix (warning: some NSFW language) in October of 2013.
The Internet has become a commodity – something we expect to be available. The simplest solution to this problem is for the FCC to classify broadband Internet access as a Title II Common Carrier, just like landline telephones. Access must be equitable and affordable, regardless of what you use it for.
Short and sweet: do you have the resources to make sure your content – or your students’ content – can be shared equally with Netflix or YouTube? Probably not.
The Internet is a truly democratic space. Yes, there are problems with culture, but the fact of the matter is that when your student creates a website, it is on the same playing field as every other website available. As a user, you should not be required to pay more for how you use the Internet – information cannot be classified as having higher value (monetary) than any other piece of information. It’s an invented factor being applied through brute force by corporations looking to make more money by inventing an economy of information. It isn’t right and it needs to be addressed.
There are various non-partisan action groups which have been battling lobbying organizations across the country. Two I recommend are Freepress.net and Fight for the Future. At the very least, sign up for one of their newsletters to receive press information, petition signups, and information on how to contact your legislator, the FCC, and the White House to voice your concern.
In 2012, I had my students write letters to our state representatives in opposition to SOPA and PIPA because of the harm they would cause to the free sharing of ideas. Net Neutrality is as important – if not more important – to schools today because of the fundamental principles underlying the creation and expansion of a free and open Internet. Ideas are important, and the Internet is crucial in sharing those ideas today. We need to be talking about this and taking action in defense of idea sharing and communication, and there’s no better place to do that than in our schools.

"Brazil are under pressure"
by BeSoccerBrazil must start getting results again after suffering a loss to Argentina, coach Tite said.
Tite accepted Brazil were under pressure after their winless run continued with a 1-0 loss to rivals Argentina in a friendly on Friday.
Lionel Messi scored the game's only goal on his return to the Argentina team in Riyadh, converting a rebound after Alisson saved his penalty in the 13th minute.
Gabriel Jesus had earlier put a penalty wide for Brazil, who are winless in five games since lifting the Copa America in July.
Tite said there was pressure on Brazil – who face South Korea in another friendly on Tuesday – amid their poor run of results.

"There is a need for the result, yes. There are moments of pressure and this is one," Tite told a news conference.
"The way we are going to look is carefully, but the need for the result occurs, even at a time of preparation."
Brazil were without the injured Neymar, and they are feeling the absence of the Paris Saint-Germain star.
Tite's side have scored just four goals in their past five games and the coach lamented Brazil's inability to take their chances.
"Translating opportunities into goals is key, and I also speak of the penalty," he said.

magnet: {
element: '.magnet'
}
});
mm.init();
One or more elements that follow the mouse.
.follow {
position: absolute;
left: 0;
top: 0;
width: 25px;
height: 25px;
background-color: #f0d647;
border-radius: 100%;
transition: transform .1s ease;
}
new MagnetMouse({
magnet: {
element: '.magnet'
},
follow: {
element: '.follow'
}
});
Change the position of the element relative to the mouse. By default it will be centered.
new MagnetMouse({
magnet: {
element: '.magnet'
position: 'center'
}
});
You have access to 2 callbacks: One when the mouse enter in the magnet effect and one when the mouse leave in the magnet effect.
Inside the callback you have access to certain data (position element and other variables) See more.
new MagnetMouse({
inCallback: function (data) {
// Make what you want
},
outCallback: function (data) {
// Make what you want
}
});
Some examples in which this library can be used.
You can make a menu with cool animation on hover.
