Twisted is a framework designed to be very flexible, and let you write powerful clients. The cost of this flexibility is a few layers in the way to writing your client. This document covers creating clients that can be used for TCP, SSL and Unix sockets. UDP is covered in a different document.
At the base, the place where you actually implement the protocol parsing
and handling, is the Protocol
class. This class will usually be
descended
from twisted.internet.protocol.Protocol
. Most
protocol handlers inherit either from this class or from one of its
convenience children. An instance of the protocol class will be instantiated
when you connect to the server and will go away when the connection is
finished. This means that persistent configuration is not saved in the
Protocol
.
The persistent configuration is kept in a Factory
class,
which usually inherits
from twisted.internet.protocol.ClientFactory
. The
default factory class just instantiates the Protocol
and then
sets the protocol's factory
attribute to point to itself (the
factory). This lets the Protocol
access, and possibly modify,
the persistent configuration.
As mentioned above, this and auxiliary classes and functions are where most of the code is. A Twisted protocol handles data in an asynchronous manner. This means that the protocol never waits for an event, but rather responds to events as they arrive from the network.
Here is a simple example:
from twisted.internet.protocol import Protocol from sys import stdout class Echo(Protocol): def dataReceived(self, data): stdout.write(data)
This is one of the simplest protocols. It just writes whatever it reads
from the connection to standard output. There are many events it does not
respond to. Here is an example of a Protocol
responding to
another event:
from twisted.internet.protocol import Protocol class WelcomeMessage(Protocol): def connectionMade(self): self.transport.write("Hello server, I am the client!\r\n") self.transport.loseConnection()
This protocol connects to the server, sends it a welcome message, and then terminates the connection.
The connectionMade
event is
usually where set up of the Protocol
object happens, as well as
any initial greetings (as in the
WelcomeMessage
protocol above). Any tearing down of
Protocol
-specific objects is done in connectionLost
.
In many cases, the protocol only needs to connect to the server once,
and the code just wants to get a connected instance of the protocol. In
those cases twisted.internet.protocol.ClientCreator
provides the
appropriate API.
from twisted.internet import reactor from twisted.internet.protocol import Protocol, ClientCreator class Greeter(Protocol): def sendMessage(self, msg): self.transport.write("MESSAGE %s\n" % msg) def gotProtocol(p): p.sendMessage("Hello") reactor.callLater(1, p.sendMessage, "This is sent in a second") reactor.callLater(2, p.transport.loseConnection) c = ClientCreator(reactor, Greeter) c.connectTCP("localhost", 1234).addCallback(gotProtocol)
We use reactor.connect*
and a ClientFactory
. The
ClientFactory
is in charge of creating
the Protocol
and also receives events relating to the
connection state. This allows it to do things like reconnect in the event of
a connection error. Here is an example of a
simple ClientFactory
that uses the Echo
protocol
(above) and also prints what state the connection is in.
from twisted.internet.protocol import Protocol, ClientFactory from sys import stdout class Echo(Protocol): def dataReceived(self, data): stdout.write(data) class EchoClientFactory(ClientFactory): def startedConnecting(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected.' return Echo() def clientConnectionLost(self, connector, reason): print 'Lost connection. Reason:', reason def clientConnectionFailed(self, connector, reason): print 'Connection failed. Reason:', reason
To connect this EchoClientFactory
to a server, you could use
this code:
from twisted.internet import reactor reactor.connectTCP(host, port, EchoClientFactory()) reactor.run()
Note that clientConnectionFailed
is called when a connection could not be established, and that clientConnectionLost
is called when a connection was made and then disconnected.
Often, the connection of a client will be lost unintentionally due to
network problems. One way to reconnect after a disconnection would be to
call connector.connect()
when the connection is lost:
from twisted.internet.protocol import ClientFactory class EchoClientFactory(ClientFactory): def clientConnectionLost(self, connector, reason): connector.connect()
The connector passed as the first argument is the interface between a
connection and a protocol. When the connection fails and the factory
receives the clientConnectionLost
event, the factory can
call connector.connect()
to start the connection over again
from scratch.
However, most programs that want this functionality should
implement ReconnectingClientFactory
instead,
which tries to reconnect if a connection is lost or fails and which
exponentially delays repeated reconnect attempts.
Here is the Echo
protocol implemented with
a ReconnectingClientFactory
:
from twisted.internet.protocol import Protocol, ReconnectingClientFactory from sys import stdout class Echo(Protocol): def dataReceived(self, data): stdout.write(data) class EchoClientFactory(ReconnectingClientFactory): def startedConnecting(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected.' print 'Resetting reconnection delay' self.resetDelay() return Echo() def clientConnectionLost(self, connector, reason): print 'Lost connection. Reason:', reason ReconnectingClientFactory.clientConnectionLost(self, connector, reason) def clientConnectionFailed(self, connector, reason): print 'Connection failed. Reason:', reason ReconnectingClientFactory.clientConnectionFailed(self, connector, reason)
The clients so far have been fairly simple. A more complicated example
comes with Twisted Words in the doc/words/examples
directory.
ircLogBot.py
connects to an IRC server, joins a channel, and
logs all traffic on it to a file. It demonstrates some of the
connection-level logic of reconnecting on a lost connection, as well as
storing persistent data in the Factory
.
Since the Protocol
instance is recreated each time the
connection is made, the client needs some way to keep track of data that
should be persisted. In the case of the logging bot, it needs to know which
channel it is logging, and where to log it.
from twisted.words.protocols import irc from twisted.internet import protocol class LogBot(irc.IRCClient): def connectionMade(self): irc.IRCClient.connectionMade(self) self.logger = MessageLogger(open(self.factory.filename, "a")) self.logger.log("[connected at %s]" % time.asctime(time.localtime(time.time()))) def signedOn(self): self.join(self.factory.channel) class LogBotFactory(protocol.ClientFactory): protocol = LogBot def __init__(self, channel, filename): self.channel = channel self.filename = filename
When the protocol is created, it gets a reference to the factory as
self.factory
. It can then access attributes of the factory in
its logic. In the case of LogBot
, it opens the file and
connects to the channel stored in the factory.
The Protocol
class used throughout this document is a base implementation
of IProtocol
used in most Twisted applications for convenience. To learn about the
complete IProtocol
interface, see the API documentation for
IProtocol
.
The transport
attribute used in some examples in this
document provides the ITCPTransport
interface. To learn
about the complete interface, see the API documentation
for ITCPTransport
.
Interface classes are a way of specifying what methods and attributes an object has and how they behave. See the Components: Interfaces and Adapters document for more information on using interfaces in Twisted.


Hi together. Im monitoring daily consumption of heatpump in kWh/D IN feed and energy produced by heatpump in kWh/D OUT feed. Both values am I presenting in bargraphs. What I need is to calculate difference between these two feeds, simply to calculate daily savings in kWh/D and present it also in daily bargraph. Im able to substract kWh/D OUT - kWh/D IN by substracting second feed from first one. But I dont know, which method to use for logging this daily difference, to be later presented as a bargraph. I tried alot of various logging methods, but result of all of them is just line graph with continous line and no bargraph with daily savings. Any idea how to substract these two feeds from each other and how to log results?
Radek
Re: Feeds difference in bargraph
Hi Radek.
If you have subtracted one feed from the other and just "log to feed" so you have an accumulating amount saved, which is what I think you have, then you should be able to use the "bargraph" visualization with the default "interval" of 86400 for daily totals and change "delta" to 1 (for true).
The only shortfall of this method is you cannot specify the time for the intervals to start and finish, so for daily each "day" is 24hrs starting and ending at what ever time you run the graph.
Paul
Re: Feeds difference in bargraph
Thanks for you fast reply, Paul. The issue is, I dont know, which kind of logging to use for saving subtracted results into feed, to be later visualised in bargraph. I tried to use phpfina, phpfiwa as wel as phptimeseries. Using anyone of these log kinds goes to visualisation only as a linegraph. This new feed is not available in selection of Bargraph visualisation.
Radek
Re: Feeds difference in bargraph
Hi Radek
I'm not entirely sure of the expected outcome of subtracting one Kwh/d from another and then logging that to a feed, The way I would do it would be to subtract the OUT Kwh feed from the IN Kwh feed and log to feed as DIFF Kwh, that feed can then be logged to a DIFF Kwh/d or use the bargraph vis as above.
Using this method I can't see how there would be any difference between IN kwh, OUT kwh and DIFF Kwh aside from values and all should be visible as daily bargraphs.If this doesn't work can you post info on your feeds, input processing and output graphs.
Re: Feeds difference in bargraph
Hi Paul,
you found it. Yes, beter than substracting kWh/D OUT - kWh/D IN is to substract power OUT - power IN and then to accumulate it into DIFF kWh. I tried and it works great.Thanks.
BUT now, another interesting calculation. Besides of calculation of longterm COP (SCOP = total kWh OUT divided by kWh IN) I would like to calculated DCOP (daily COP). Im calculating now daily kWh OUT divided by daily kWh IN = DCOP. The issue is, after midnight, daily kWh values are cleared to zero value, what brings problem with dividing operation. Do you have any idea, how to calculate daily values of DCOP and to present them in bargraph?
Radek
Re: Feeds difference in bargraph
No, sorry not off-hand "divide by zero" errors will be an issue. but if I think of something I'll let you know .
Paul

'Good Newwz': Ahead of the trailer release, Akshay Kumar shares an intriguing poster of his upcoming film
by TIMESOFINDIA.COMA few days back, the makers of Akshay Kumar and Kareena Kapoor Khan starrer 'Good Newwz' dropped a few posters of the film. They also announced the release date of the much-awaited trailer. The makers are going to unveil the trailer today and their fans can't keep calm. Ahead of the trailer release, Akki took to his Instagram handle to share a new poster!

The poster features Akshay, Kareena, Kiara Advani and Diljit Dosanjh. As per their tagline, the film will be a rom-com filled with confusions and goof-ups. Bebo and Kiara look stunning in the poster. He wrote, ''As you can see, we're all in this together! #GoodNewwzTrailer out today at noon!😀''. The film will be Akshay Kumar's last release of 2019 and will be Kareena's second Bollywood film post-pregnancy.
The 'Gold' actor even shared a motion poster, where we can see Akshay and Diljit's heads are squeezed between Kareena and Kiara's baby bumps. Akki and Diljit are seen troubled by their expressions.
Helmed by Raj Mehta, the film is scheduled to hit the silver screens on 27th of December, 2019.

The goal of this script is to provide a fast and lightweight (3kb minified / 1kb gzipped) script to enable responsive web designs in browsers that don't support CSS3 Media Queries - in particular, Internet Explorer 8 and under. It's written in such a way that it will probably patch support for other non-supporting browsers as well (more information on that soon).
If you're unfamiliar with the concepts surrounding Responsive Web Design, you can read up here and also here
Demo page (the colors change to show media queries working)
Craft your CSS with min/max-width media queries to adapt your layout from mobile (first) all the way up to desktop
@media screen and (min-width: 480px){ ...styles for 480px and up go here }
Reference the respond.min.js script (1kb min/gzipped) after all of your CSS (the earlier it runs, the greater chance IE users will not see a flash of un-media'd content)
Crack open Internet Explorer and pump fists in delight
Respond.js works by requesting a pristine copy of your CSS via AJAX, so if you host your stylesheets on a CDN (or a subdomain), you'll need to upload a proxy page to enable cross-domain communication.
See cross-domain/example.html
for a demo:
cross-domain/respond-proxy.html
to your external domaincross-domain/respond.proxy.gif
to your origin domain<link />
element(s):<!-- Respond.js proxy on external server --> <link href="http://externalcdn.com/respond-proxy.html" id="respond-proxy" rel="respond-proxy" /> <!-- Respond.js redirect location on local server --> <link href="/path/to/respond.proxy.gif" id="respond-redirect" rel="respond-redirect" /> <!-- Respond.js proxy script on local server --> <script src="/path/to/respond.proxy.js"></script>
If you are having problems with the cross-domain setup, make sure respond-proxy.html does not have a query string appended to it.
Note: HUGE thanks to @doctyper for the contributions in the cross-domain proxy!
Some notes to keep in mind:
This script's focus is purposely very narrow: only min-width and max-width media queries and all media types (screen, print, etc) are translated to non-supporting browsers. I wanted to keep things simple for filesize, maintenance, and performance, so I've intentionally limited support to queries that are essential to building a (mobile-first) responsive design. In the future, I may rework things a bit to include a hook for patching-in additional media query features - stay tuned!
Browsers that natively support CSS3 Media Queries are opted-out of running this script as quickly as possible. In testing for support, all other browsers are subjected to a quick test to determine whether they support media queries or not before proceeding to run the script. This test is now included separately at the top, and uses the window.matchMedia polyfill found here: https://github.com/paulirish/matchMedia.js . If you are already including this polyfill via Modernizr or otherwise, feel free to remove that part.
 This is a good thing, because that allows it to run really fast, but its looseness may also cause unexpected behavior. For example: if you enclose a whole media query in a comment intending to disable its rules, you'll probably find that those rules will end up enabled in non-media-query-supporting browsers.
Respond.js doesn't parse CSS referenced via @import, nor does it work with media queries within style elements, as those styles can't be re-requested for parsing.
Due to security restrictions, some browsers may not allow this script to work on file:// urls (because it uses xmlHttpRequest). Run it on a web server.
If the request for the CSS file that includes MQ-specific styling is behind a redirect, Respond.js will fail silently. CSS files should respond with a 200 status.
Currently, media attributes on link elements are supported, but only if the linked stylesheet contains no media queries. If it does contain queries, the media attribute will be ignored and the internal queries will be parsed normally. In other words, @media statements in the CSS take priority.
Reportedly, if CSS files are encoded in UTF-8 with Byte-Order-Mark (BOM), they will not work with Respond.js in IE7 or IE8. Noted in issue #97
WARNING: Including @font-face rules inside a media query will cause IE7 and IE8 to hang during load. To work around this, place @font-face rules in the wide open, as a sibling to other media queries.
If you have more than 32 stylesheets referenced, IE will throw an error, Invalid procedure call or argument
. Concatenate your CSS and the issue should go away.
Sass/SCSS source maps are not supported; @media -sass-debug-info
will break respond.js. Noted in issue #148
Internet Explorer 9 supports css3 media queries, but not within frames when the CSS containing the media query is in an external file (this appears to be a bug in IE9 — see http://stackoverflow.com/questions/10316247/media-queries-fail-inside-ie9-iframe). See this commit for a fix if you're having this problem. https://github.com/NewSignature/Respond/commit/1c86c66075f0a2099451eb426702fc3540d2e603
Nested Media Queries are not supported
Basically, the script loops through the CSS referenced in the page and runs a regular expression or two on their contents to find media queries and their associated blocks of CSS. In Internet Explorer, the content of the stylesheet is impossible to retrieve in its pre-parsed state (which in IE 8-, means its media queries are removed from the text), so Respond.js re-requests the CSS files using Ajax and parses the text response from there. Be sure to configure your CSS files' caching properly so that this re-request doesn't actually go to the server, hitting your browser cache instead.
From there, each media query block is appended to the head in order via style elements, and those style elements are enabled and disabled (read: appended and removed from the DOM) depending on how their min/max width compares with the browser width. The media attribute on the style elements will match that of the query in the CSS, so it could be "screen", "projector", or whatever you want. Any relative paths contained in the CSS will be prefixed by their stylesheet's href, so image paths will direct to their proper destination
Sure, a couple:
This isn't the only CSS3 Media Query polyfill script out there; but it damn well may be the fastest.
If you're looking for more robust CSS3 Media Query support, you might check out http://code.google.com/p/css3-mediaqueries-js/. In testing, I've found that script to be noticeably slow when rendering complex responsive designs (both in filesize and performance), but it really does support a lot more media query features than this script. Big hat tip to the authors! :)

Hybrid Vehickles Rock
My parents picked up 2 Honda Civic Hybrids, and then got rid of one of the Civics to get the 2005 Honda Accord Hybrid. (As a real-estate agent in a place where the temperature gets insanely hot, you MUST be able to air condition the back seat!)
I have to say, I'm pretty freaking impressed. I don't understand why every vehicle wouldn't have the recuperative braking, or an instantaneous energy usage meter to help you control your driving patterns. And shutting off the engine when you're not moving is brilliant. More later, if I ever have time...

Sources of Data in ChemData.csv¶
- Release
2.1
- Date
Jun 05, 2020
The following list documents the sources of data in the ./data/ChemData.csv file.
Molecular weights (M) are from the periodic table in Fine & Beall, 1990, Chemistry for Engineers and Scientists, Saunders College Publishing: Philedelphia, Pennsylvania. Data are in (g/mol).
Critical-point data (Pc, Tc, Vc) are mostly from McCain, 1990, The Properties of Petroleum Fluids, 2nd Edition, PennWell Books: Tulsa, Oklahoma. Exceptions are for Argon, which is from P.4-127 of the Handbook of Chemistry and Physics, 71st Edition. The data are in psia for pressure and R for temperature.
Boiling point (Tb, Vb) are from Poling et al., 2001, The Properties of gases and liquids, 5th ed., McGraw Hill. Data not in Poling et al. are from the group contribution method by Kurtz and Sankin, 1954, Calculation of molar volumes of hydrocarbons over a wide range of temperatures and pressures, Industrial and Engineering Chemistry, 46(10), 2186-2191.
Acentric factors (omega) are mostly from McCain, 1990, The Properties of Petroleum Fluids, 2nd Edition, PennWell Books: Tulsa, Oklahoma. Exceptions are for Argon, which is from P.4-127 of the Handbook of Chemistry and Physics, 71st Edition. The data are in psia for pressure and R for temperature.
Henry’s law constants (kh_0) are from Sander 1999, Compilation of Henry’s Law Constants for Inorganic and Organic Species of Potential Importance in Environmental Chemistry, downloaded from http://www.rolf-sander.net/henry/henry.pdf on January 2, 2012. The data are in mol/(dm^3 atm).
Enthalpy of solution (dH_solR) are from Sander 1999, Compilation of Henry’s Law Constants for Inorganic and Organic Species of Potential Importance in Environmental Chemistry, downloaded from http://www.rolf-sander.net/henry/henry.pdf on January 2, 2012. The data in the table are the negative of the enthalpy of solution (so that the values are positive) and are normalized by the universal gas constant R and reported in K.
Specific volume at infinite dilution (nu_bar) are from Wilhelm et al., 1977, Low-pressure solubility of gases in liquid water, Chemical Reviews, 77(2): pp. 219-262.
Diffusivity model coefficients (B, dE) are from Wise and Houghton, 1966, The diffusion coefficients of ten slightly soluble gases in water at 10-60 deg C, Chemical Engineering Science, 21: pp. 999-1010. The data are in cm^2/sec (B) and cal/mol (dE).

This course introduces useful things...
| Lectures | will focus on conceptual things. |
| Homework | will ask students to apply their knowledge of things. |
| Team Project | will allow students to collaboratively work on a real-life example of things |
The final grade for this course will be weighted as follows...
Final grades will be assigned based on the following scale...

Submissions will be made via Blackboard. Code is expected to be professional and properly documented; any required data files/libraries must be included.
This class has very strict standards for borrowing code: if you borrow anything for use in your homework/project, you must have a citation. A good guideline is that if you take more than three lines of code from some source, you must include the information on where it came from. A URL or a notation (e.g., "MATLAB help files") is fine. If it is an entire function, note it at the beginning of the code segment and include any original credit information. Provide a qualitative description of what you used, and what you changed/contributed. If you have a question about what is considered a violation of this policy, ASK!
The university's academic integrity policy discusses actions regarded as violations and consequences for students: http://www.northeastern.edu/osccr/academic-integrity
The goal of the project is to gain hands-on experience with developing things from the ground up.
Note: This schedule is subject to change and will be adjusted as needed throughout the semester.

5.1 | Final! |
Students are expected to read the materials in preparation of each lecture.
To create and preserve a classroom atmosphere that optimizes teaching and learning, all participants share a responsibility in creating a civil and non-disruptive forum for the discussion of ideas. Students are expected to conduct themselves at all times in a manner that does not disrupt teaching or learning. Your comments to others should be constructive and free from harassing statements. You are encouraged to disagree with other students and the instructor, but such disagreements need to respectful and be based upon facts and documentation (rather than prejudices and personalities). The instructor reserves the right to interrupt conversations that deviate from these expectations. Repeated unprofessional or disrespectful conduct may result in a lower grade or more severe consequences. Part of the learning process in this course is respectful engagement of ideas with others.
Title IX of the Education Amendments of 1972 protects individuals from sex or gender-based discrimination, including discrimination based on gender-identity, in educational programs and activities that receive federal financial assistance.
 The Title IX Policy applies to the entire community, including male, female, transgender students, faculty and staff.
If you or someone you know has been a survivor of a Prohibited Offense, confidential support and guidance can be found through University Health and Counseling Services staff (http://www.northeastern.edu/uhcs/) and the Center for Spiritual Dialogue and Service clergy members (http://www.northeastern.edu/spirituallife/). By law, those employees are not required to report allegations of sex or gender-based discrimination to the University.
Alleged violations can be reported non-confidentially to the Title IX Coordinator within The Office for Gender Equity and Compliance at<EMAIL_ADDRESS>and/or through NUPD (Emergency<PHONE_NUMBER>; Non-Emergency<PHONE_NUMBER>). Reporting Prohibited Offenses to NUPD does NOT commit the victim/affected party to future legal action.
Faculty members are considered "responsible employees" at Northeastern University, meaning they are required to report all allegations of sex or gender-based discrimination to the Title IX Coordinator.
In case of an emergency, please call 911.
Please visit http://www.northeastern.edu/titleix for a complete list of reporting options and resources both on- and off-campus.
Students who have disabilities who wish to receive academic services and/or accommodations should visit the Disability Resource Center at 20 Dodge Hall or call<PHONE_NUMBER>. If you have already done so, please provide your letter from the DRC to me early in the semester so that I can arrange those accommodations.

Java Switch StatementThe Java switch statement executes one statement from multiple conditions. It is like if-else-if ladder statement. The switch statement works with byte, short, int, long, enum types, String and some wrapper types like Byte, Short, Int, and Long. Since Java 7, you can use strings in the switch statement. In other words, the switch statement tests the equality of a variable against multiple values. Points to Remember
Syntax: Example: Output: 20 Finding Month Example: Output: 7 - July Program to check Vowel or Consonant: If the character is A, E, I, O, or U, it is vowel otherwise consonant. It is not case-sensitive. Output: Vowel Java Switch Statement is fall-throughThe Java switch statement is fall-through. It means it executes all statements after the first match if a break statement is not present. Example: Output: 20 30 Not in 10, 20 or 30 Java Switch Statement with StringJava allows us to use strings in switch expression since Java SE 7. The case statement should be string literal. Example: Output: Your Level is: 3 Java Nested Switch StatementWe can use switch statement inside other switch statement in Java. It is known as nested switch statement. Example: Output: Data Communication and Networks, MultiMedia Java Enum in Switch StatementJava allows us to use enum in switch statement. Example: Output: Sunday Monday Twesday Wednesday Thursday Friday Saturday Java Wrapper in Switch StatementJava allows us to use four wrapper classes: Byte, Short, Integer and Long in switch statement. Example: Output: You are eligible for vote.

Last bookings are 45 minutes before closing.
You will be entered into the next round and will receive a welcoming email when the round commences. The email includes player contact numbers and the login details for the tables page which includes player email links. You will need to arrange your own games with each player in your division and add your scores via the website. Scores are updated every few days so don't worry if your score doesn't appear on the scores page straight away.
New players usually start in the 'New Players' division and work their way up the tables. We try and fast track players that show particular talent though this isn't always possible. You can see the current league status and round starting dates on the home page or the league calendar.
Players are responsible for contacting the 2 or 3 players below them, depending on how many players are in their box. See the table below.
| SYSTEM FOR ARRANGING MATCHES | |||
| PLAYER | 5 PLAYER BOX | 6 PLAYER BOX | 7 PLAYER BOX |
| 1 | 2,3 | 2,3 | 2,3,4 |
| 2 | 3,4 | 3,4 | 3,4,5 |
| 3 | 4,5 | 4,5 | 4,5,6 |
| 4 | 5,1 | 5,6,1 | 5,6,7 |
| 5 | 1,2 | 6,1,2 | 6,7,1 |
| 6 | 1,2,3 | 7,1,2 | |
| 7 | 1,2,3 |
You can contact players by using the mail links on the tables page (click on a players name). Alternatively, all player contact numbers are emailed to league members at the start of each round. If you haven't received them drop us an email and we will email them to you.
No. League members voted in favour of sticking with the 'Server only Scores' English scoring system where games are played to 9 points and not 11. Players can use the new PAR system if they wish, though this needs to be agreed between both players before the match commences.
If the league is to run successfully all league members must play as many games as possible during each round. Consistently inactive players will be removed from the league, so do drop us an email if you have a genuine reason why you can't play. Players who don't play any of their games in a round and don't get in contact are automatically removed from the tables.
If you're injured and are unable to play, please drop us an email so we can mark you as injured on the tables. You will remain marked as injured until you notify us when you're able to play again. If you haven't played many of your allotted matches at time of injury and plan on not returning to the current round, your match scores for that round will be wiped. If you have played most of your matches at time of injury, your current match scores will remain on the tables.
A player usually drops a division on returning from an injury. In the interest of the league, players who don't play any games during a round and don't get in touch are automatically removed from the tables.
All league matches are to be played with a double yellow spot ball unless both players agree to use a different type.
The members login info is included in the league welcoming email which is automatically sent to you when you fill in the joining form. If you have not received this email, it may be in your spam folder. They are also sent out via email to every player along with player contact details at the start of each round. Check the calendar for round commencement dates.
If you've tried to contact a player several times and had no response, drop us an email and we will try and contact the player. If there is still no response, you will either be awarded a walk-over or the offending player will be removed from the tables, depending on the circumstances.
Our forms have a monthly limit on them. This limit is sometimes reached before the end of each month and this prevents the forms from working. You will know this has happened when the score/join page says 'Sorry, but this form is no longer accepting submissions'. If you are looking to submit a score, please contact us via email stating your name, your opponents name, division and score. If you are looking to join, please contact us via email stating your name, phone number and email address and we will be in touch.
The score system is not automatic and we have to enter scores manually so scores won't appear straight away once you've submitted them. We tend to update the scores 2 or 3 times a week.

Docker
Docker is software for automating the deployment and management of applications in containerized environments.
Docker Allows you to "pack" the application with all its surroundings and dependencies into a container that can be transferred to any system, and also provides an environment for managing containers.
Docker consists of the following components:
- Docker engine
- Docker hub
- Docker swarm
- Docker compose
- Docker kinematic
- Docker machine
What is a container ??
A container is a packaged application with all its dependencies and the environment.
Pros of using a container:
- Simple launch of the container
- Guarantee that our application will run on a different host
- High performance and speed

Frank Ocean releases single 'In My Room'
Follow up comes two weeks after 'DHL'
by Alaa Elassar, CNNLOS ANGELES - It's only been two weeks, and R&B singer Frank Ocean has already released another surprise single. Are we in heaven?
Ocean released "In My Room" on Saturday through Apple Music. The song is currently unavailable on any other streaming platform.
The new track comes on the heels of Ocean's recent single "DHL," which was released on October 19 after premiering at the end of "Blonded," his Beats 1 radio show.
Ocean hosted a Halloween edition of his PrEP+ clubnight in New York on Thursday, where fans got a special treat when "In My Room" was played during the event.
"DHL" was released with art depicting a man sitting on a chair with one arm raised and his head in a bag, a unique pose that matched one of 13 silhouettes beneath the image. Fans had theorized the silhouettes represent new songs.
It's unclear if that's true. However, "In My Room" was also paired with cover art matching one of 17 silhouettes.

Scripting languages were designed in part in order to help people do repetitive tasks quickly and simply. One of the common things webmasters, system administrators, and programmers need to do is to take a set of files, select a subset of those files, do some sort of manipulation on this subset, and write the output to one or a set of output files. (For example, in each file in a directory, find the last word of every other line that starts with something other than the # character, and print it along with the name of the file.) This is a task for which special-purpose tools have been developed, such as sed and awk. We find that Python does the job just fine using very simple tools.
The sys module is most helpful when it comes to dealing with an input file, parsing the text it contains and processing it. Among its attributes are three file objects, called sys.stdin , sys.stdout , and sys.stderr . The names come from the notion of the three streams, called standard in, standard out, and standard error, which are used to connect command line tools. Standard output (stdout) is used by every print statement. It's a file object with all the output methods of file objects opened in write mode, such as write and writelines. The other often-used stream is standard in (stdin), which is also a file object, but with the input methods, such as read, readline, and readlines. For example, the following script counts all the lines in the file that is "piped in":
import sys data = sys.stdin.readlines() print "Counted", len(data), "lines."
On Unix, you could test it by doing something like:
% cat countlines.py | python countlines.py Counted 3 lines.
On Windows or DOS, you'd do:
C:\> type countlines.py | python countlines.py Counted 3 lines.
The readlines function is useful when implementing simple filter operations. Here are a few examples of such filter operations:
import sys for line in sys.stdin.readlines(): if line[0] == '#': print line,
Note that a final comma is needed after the print statement because the line string already includes a newline character as its last character.
import sys, string for line in sys.stdin.readlines(): words = string.split(line) if len(words) >= 4: print words[3]
We look at the length of the words list to find if there are indeed at least four words. The last two lines could also be replaced by the try/except idiom, which is quite common in Python:
try: print words[3] except IndexError: # there aren't enough words pass
import sys, string for line in sys.stdin.readlines(): words = string.split(line, ':') if len(words) >= 4: print string.lower(words[3])
import sys, string lines = sys.stdin.readlines() sys.stdout.writelines(lines[:10]) # first ten lines sys.stdout.writelines(lines[-10:]) # last ten lines for lineIndex in range(0, len(lines), 2): # get 0, 2, 4, ... sys.stdout.write(lines[lineIndex]) # get the indexed line
import string text = open(fname).read() print string.count(text, 'Python')
In this more complicated example, the task is to "transpose" a file; imagine you have a file that looks like:
Name: Willie Mark Guido Mary Rachel Ahmed Level: 5 4 3 1 6 4 Tag#: 1234 4451 5515 5124 1881 5132
And you really want it to look like the following instead:
Name: Level: Tag#: Willie 5 1234 Mark 4 4451 ...
You could use code like the following:
import sys, string lines = sys.stdin.readlines() wordlists = [] for line in lines: words = string.split(line) wordlists.append(words) for row in range(len(wordlists[0])): for col in range(len(wordlists)): print wordlists[col][row] + '\t', print
Of course, you should really use much more defensive programming techniques to deal with the possibility that not all lines have the same number of words in them, that there may be missing data, etc. Those techniques are task-specific and are left as an exercise to the reader.
All the preceding examples assume you can read the entire file at once (that's what the readlines call expects). In some cases, however, that's not possible, for example when processing really huge files on computers with little memory, or when dealing with files that are constantly being appended to (such as log files). In such cases, you can use a while/readline combination, where some of the file is read a bit at a time, until the end of file is reached. In dealing with files that aren't line-oriented, you must read the file a character at a time:
# read character by character while 1: next = sys.stdin.read(1) # read a one-character string if not next: # or an empty string at EOF breakProcess character 'next'
Notice that the read() method on file objects returns an empty string at end of file, which breaks out of the while loop. Most often, however, the files you'll deal with consist of line-based data and are processed a line at a time:
# read line by line while 1: next = sys.stdin.readline() # read a one-line string if not next: # or an empty string at EOF breakProcess line 'next'
Being able to read stdin is a great feature; it's the foundation of the Unix toolset. However, one input is not always enough: many tasks need to be performed on sets of files. This is usually done by having the Python program parse the list of arguments sent to the script as command-line options. For example, if you type:
% python myScript.py input1.txt input2.txt input3.txt output.txt
you might think that myScript.py wants to do something with the first three input files and write a new file, called output.txt. Let's see what the beginning of such a program could look like:
import sysinputfilenames, outputfilename = sys.argv[1:-1], sys.argv[-1]for inputfilename in inputfilenames: inputfile = open(inputfilename, "r") do_something_with_input(inputfile) outputfile = open(outputfilename, "w") write_results(outputfile)
The second line extracts parts of the argv attribute of the sys module. Recall that it's a list of the words on the command line that called the current program. It starts with the name of the script. So, in the example above, the value of sys.argv is:
['myScript.py', 'input1.txt', 'input2.txt', 'input3.txt', 'output.txt'].
The script assumes that the command line consists of one or more input files and one output file. So the slicing of the input file names starts at 1 (to skip the name of the script, which isn't an input to the script in most cases), and stops before the last word on the command line, which is the name of the output file. The rest of the script should be pretty easy to understand (but won't work until you provide the do_something_with_input() and write_results() functions).
Note that the preceding script doesn't actually read in the data from the files, but passes the file object down to a function to do the real work. Such a function often uses the readlines() method on file objects, which returns a list of the lines in that file. A generic version of do_something_with_input() is:
def do_something_with_input(inputfile): for line in inputfile.readlines() process(line)
The combination of this idiom with the preceding one regarding opening each file in the sys.argv[1:] list is so common that Python 1.5 introduced a new module that's designed to help do just this task. It's called fileinput and works like this:
import fileinput for line in fileinput.input(): process(line)
The fileinput.input() call parses the arguments on the command line, and if there are no arguments to the script, uses sys.stdin instead. It also provides a bunch of useful functions that let you know which file and line number you're currently manipulating:
import fileinput, sys, string # take the first argument out of sys.argv and assign it to searchterm searchterm, sys.argv[1:] = sys.argv[1], sys.argv[2:] for line in fileinput.input(): num_matches = string.count(line, searchterm) if num_matches: # a nonzero count means there was a match print "found '%s' %d times in %s on line %d." % (searchterm, num_matches, fileinput.filename(), fileinput.filelineno())
If this script were called mygrep.py, it could be used as follows:
% python mygrep.py in *.py found 'in' 2 times in countlines.py on line 2. found 'in' 2 times in countlines.py on line 3. found 'in' 2 times in mygrep.py on line 1. found 'in' 4 times in mygrep.py on line 4. found 'in' 2 times in mygrep.py on line 5. found 'in' 2 times in mygrep.py on line 7. found 'in' 3 times in mygrep.py on line 8. found 'in' 3 times in mygrep.py on line 12.
We have now covered reading existing files, and if you remember the discussion on the open built-in function in Chapter 2, you know how to create new files. There are a lot of tasks, however, that need different kinds of file manipulations, such as directory and path management and removing files. Your two best friends in such cases are the os and os.path modules described in Chapter 8.
Let's take a typical example: you have lots of files, all of which have a space in their name, and you'd like to replace the spaces with underscores. All you really need is the os.curdir attribute (which returns an operating-system specific string that corresponds to the current directory), the os.listdir function (which returns the list of filenames in a specified directory), and the os.rename function:
import os, string if len(sys.argv) == 1: # if no filenames are specified, filenames = os.listdir(os.curdir) # use current dir else: # otherwise, use files specified filenames = sys.argv[1:] # on the command line for filename in filenames: if ' ' in filename: newfilename = string.replace(filename, ' ', '_') print "Renaming", filename, "to", newfilename, "..." os.rename(filename, newfilename)
This program works fine, but it reveals a certain Unix-centrism. That is, if you call it with wildcards, such as:
python despacify.py *.txt
you find that on Unix machines, it renames all the files with names with spaces in them and that end with .txt. In a DOS-style shell, however, this won't work because the shell normally used in DOS and Windows doesn't convert from *.txt to the list of filenames; it expects the program to do it. This is called globbing, because the * is said to match a glob of characters.
The glob module exports a single function, also called glob, which takes a filename pattern and returns a list of all the filenames that match that pattern (in the current working directory):
import sys, glob, operator print sys.argv[1:] sys.argv = reduce(operator.add, map(glob.glob, sys.argv)) print sys.argv[1:]
Running this on Unix and DOS shows that on Unix, the Python glob didn't do anything because the globbing was done by the Unix shell before Python was invoked, and on DOS, Python's globbing came up with the same answer:
/usr/python/book$ python showglob.py *.py ['countlines.py', 'mygrep.py', 'retest.py', 'showglob.py', 'testglob.py'] ['countlines.py', 'mygrep.py', 'retest.py', 'showglob.py', 'testglob.py'] C:\python\book> python showglob.py *.py ['*.py'] ['countlines.py', 'mygrep.py', 'retest.py', 'showglob.py', 'testglob.py']
This script isn't trivial, though, because it uses two conceptually difficult operations; a map followed by a reduce. map was mentioned in Chapter 4, but reduce is new to you at this point (unless you have background in LISP-type languages). map is a function that takes a callable object (usually a function) and a sequence, calls the callable object with each element of the sequence in turn, and returns a list containing the values returned by the function. For an graphical representation of what map does, see Figure 9.1.[3]
[3] It turns out that map can do more; for example, if None is the first argument, map converts the sequence that is its second argument to a list. It can also operate on more than one sequence at a time. Check a reference source for details.
map is needed here (or something equivalent) because you don't know how many arguments were entered on the command line (e.g., it could have been *.py *.txt *.doc). So the glob.glob function is called with each argument in turn. Each glob.glob call returns a list of filenames that match the pattern. The map operation then returns a list of lists, which you need to convert to a single list—the combination of all the lists in this list of lists. That means doing list1 + list2 + ... + listN. That's exactly the kind of situation where the reduce function comes in handy.
Just as with map, reduce takes a function as its first argument and applies it to the first two elements of the sequence it receives as its second argument. It then takes the result of that call and calls the function again with that result and the next element in the sequence, etc. (See Figure 9.2 for an illustration of reduce.) But wait: you need + applied to a set of things, and + doesn't look like a function (it isn't). So a function is needed that works the same as +. Here's one:
define myAdd(something, other): return something + other
You would then use reduce(myAdd, map(...)). This works fine, but better yet, you can use the add function defined in the operator module, which does the same thing. The operator module defines functions for every syntactic operation in Python (including attribute-getting and slicing), and you should use those instead of homemade ones for two reasons. First, they've been coded, debugged, and tested by Guido, who has a pretty good track record at writing bugfree code. Second, they're actually C functions, and applying reduce (or map, or filter) to C functions results in much faster performance than applying it to Python functions. This clearly doesn't matter when all you're doing is going through a few hundred files once. If you do thousands of globs all the time, however, speed can become an issue, and now you know how to do it quickly.
The filter built-in function, like map and reduce, takes a function and a sequence as arguments. It returns the subset of the elements in the sequence for which the specified function returns something that's true. To find all of the even numbers in a set, type this:
>>> numbers = range(30)
>>> def even(x):
... return x % 2 == 0
... >>> print numbers
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29] >>> print filter(even, numbers)
[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28]
Or, if you wanted to find all the words in a file that are at least 10 characters long, you could use:
import string words = string.split(open('myfile.txt').read()) # get all the words def at_least_ten(word): return len(word) >= 10 longwords = filter(at_least_ten, words)
For a graphical representation of what filter does, see Figure 9.3. One nice special feature of filter is that if one passes None as the first argument, it filters out all false entries in the sequence. So, to find all the nonempty lines in a file called myfile.txt, do this:
lines = open('myfile.txt').readlines() lines = filter(None, lines) # remember, the empty string is false
map, filter, and reduce are three powerful constructs, and they're worth knowing about; however, they are never necessary. It's fairly simple to write a Python function that does the same thing as any of them. The built-in versions are prob-ably faster, especially when operating on built-in functions written in C, such as the functions in the operator module.
If you've ever written a shell script and needed to use intermediary files for storing the results of some intermediate stages of processing, you probably suffered from directory litter. You started out with 20 files called log_001.txt, log_002.txt etc., and all you wanted was one summary file called log_sum.txt.  At least that's what we've seen happen in our own lives. To put order back into your directories, use temporary files in specific directories and clean them up afterwards.
To help in this temporary file-management problem, Python provides a nice little module called tempfile that publishes two functions: mktemp() and TemporaryFile(). The former returns the name of a file not currently in use in a directory on your computer reserved for temporary files (such as /tmp on Unix or C:\TMP on Windows). The latter returns a new file object directly. For example:
# read input file inputFile = open('input.txt', 'r') import tempfile # create temporary file tempFile = tempfile.TemporaryFile() # we don't even need to first_process(input = inputFile, output = tempFile) # know the filename... # create final output file outputFile = open('output.txt', 'w') second_process(input = tempFile, output = outputFile)
Using tempfile.TemporaryFile() works well in cases where the intermediate steps manipulate file objects. One of its nice features is that when it's deleted, it automatically deletes the file it created on disk, thus cleaning up after itself. One important use of temporary files, however, is in conjunction with the os.system call, which means using a shell, hence using filenames, not file objects. For example, let's look at a program that creates form letters and mails them to a list of email addresses (on Unix only):
formletter = """Dear %s,\nI'm writing to you to suggest that ...""" # etc. myDatabase = [('Bill Clinton', 'bill@whitehouse.gov.us'), ('Bill Gates', 'bill@microsoft.com'), ('Bob', 'bob@subgenius.org')] for name, email in myDatabase: specificLetter = formletter % name tempfilename = tempfile.mktemp() tempfile = open(tempfilename, 'w') tempfile.write(specificLetter) tempfile.close() os.system('/usr/bin/mail %(email)s -s "Urgent!" < %(tempfilename)s' % vars()) os.remove(tempfilename)
The first line in the for loop returns a customized version of the form letter based on the name it's given. That text is then written to a temporary file that's emailed to the appropriate email address using the os.system call (which we'll cover later in this chapter). Finally, to clean up, the temporary file is removed. If you forgot how the % bit works, go back to Chapter 2 and review it; it's worth knowing. The vars() function is a built-in function that returns a dictionary corresponding to the variables defined in the current local namespace. The keys of the dictionary are the variable names, and the values of the dictionary are the variable values. vars() comes in quite handy for exploring namespaces. It can also be called with an object as an argument (such as a module, a class, or an instance), and it will return the namespace of that object. Two other built-ins, locals() and globals(), return the local and global namespaces, respectively. In all three cases, modifying the returned dictionaries doesn't guarantee any effect on the namespace in question, so view these as read-only and you won't be surprised. You can see that the vars() call creates a dictionary that is used by the string interpolation mechanism; it's thus important that the names inside the %(...)s bits in the string match the variable names in the program.
Suppose you've run a program that stores its output in a text file, which you need to load. The program creates a file that's composed of a series of lines that each contain a value and a key separated by whitespace:
value key value key value keyand so on...
A key can appear on more than one line in the file, and you'd probably like to collect all the values that appear for each given key as you scan the file. Here's one way to solve this problem:
#!/usr/bin/env python import sys, string entries = {} for line in open(sys.argv[1], 'r').readlines(): left, right = string.split(line) try: entries[right].append(left) # extend list except KeyError: entries[right] = [left] # first time seen for (right, lefts) in entries.items(): print "%04d '%s'\titems => %s" % (len(lefts), right, lefts)
This script uses the readlines method to scan the text file line by line, and calls the built-in string.split function to chop the line into a list of substrings—a list containing the value and key strings separated by blanks or tabs in the file. To store all occurrences of a key, the script uses a dictionary called entries. The try statement in the loop tries to add new values to an existing entry for a key; if no entry exists for the key, it creates one. Notice that the try could be replaced with an if here:
if entries.has_key(right): # is it already in the dictionary? entries[right].append(left) # add to the list of current values for key else: entries[right] = [left] # initialize key's values list
Testing whether a dictionary contains a key is sometimes faster than catching an exception with the try technique; it depends on how many times the test is true. Here's an example of this script in action. The input filename is passed in as a command-line argument (sys.argv[1]):
% cat data.txt 1 one 2 one 3 two 7 three 8 two 10 one 14 three 19 three 20 three 30 three % python collector1.py data.txt 0003 'one' items => ['1', '2', '10'] 0005 'three' items => ['7', '14', '19', '20', '30'] 0002 'two' items => ['3', '8']
You can make this code more useful by packaging the scanner logic in a function that returns the entries dictionary as a result and wrapping the printing loop logic at the bottom in an if test:
#!/usr/bin/env python import sys, string def collect(file): entries = {} for line in file.readlines(): left, right = string.split(line) try: entries[right].append(left) # extend list except KeyError: entries[right] = [left] # first time seen return entries if __name__ == "__main__": # when run as a script if len(sys.argv) == 1: result = collect(sys.stdin) # read from stdin stream else: result = collect(open(sys.argv[1], 'r')) # read from passed filename for (right, lefts) in result.items(): print "%04d '%s'\titems => %s" % (len(lefts), right, lefts)
This way, the program becomes a bit more flexible. By using the if __name__ == "__main_ _" trick, you can still run it as a top-level script (and get a display of the results), or import the function it defines and process the resulting dictionary explicitly:
# run as a script file % collector2.py < data.txt result displayed here... # use in some other component (or interactively) from collector2 import collect result = collect(open("spam.txt", "r")) process result here...
Since the collect function accepts an open file object, it also works on any object that provides the methods (i.e., interface) built-in files do. For example, if you want to read text from a simple string, wrap it in a class that implements the required interface and pass an instance of the class to the collect function:
>>> from collector2 import collect >>> from StringIO import StringIO >>> >>> str = StringIO("1 one\n2 one\n3 two") >>> result = collect(str) # scans the wrapped string >>> print result # {'one':['1','2'],'two':['3']}
This code uses the StringIO class in the standard Python library to wrap the string into an instance that has all the methods file objects have; see the Library Reference for more details on StringIO. You could also write a different class or subclass from StringIO if you need to modify its behavior. Regardless, the collect function happily reads text from the StringIO object str, which happens to be an in-memory object, not a file.
The main reason all this works is that the collect function was designed to avoid making assumptions about the type of object its file parameter references. As long as the object exports a readlines method that returns a list of strings, collect doesn't care what type of object it processes. The interface is all that matters. This runtime binding[4] is an important feature of Python's object system, and allows you to easily write component programs that communicate with other components. For instance, consider a program that reads and writes satellite telemetry data using the standard file interface. By plugging in an object with the right sort of interface, you can redirect its streams to live sockets, GUI boxes, web interfaces, or databases without changing the program i tself or even recompiling it.
[4] Runtime binding means that Python doesn't know which sort of object implements an interface until the program is running. This behavior stems from the lack of type declarations in Python and leads to the notion of polymorphism; in Python, the meaning of a object operation (such as indexing, slicing, etc.) depends on the object being operated on.

Description of package;
MIDI.loadPlugin.js: Decides which framework is best to use, and sends request.
// interface to download soundfont, then execute callback;
MIDI.loadPlugin(callback, soundfont);
// simple example to get started;
MIDI.loadPlugin(function() {
MIDI.noteOn(0, 100, 127, 0); // plays note once loaded
}, "soundfont/soundfont-ogg-guitar.js");
MIDI.Soundfont.js: Customizable base64 Soundfont.
Encode your own soundfonts, Drums, Guitars, and so on.
Share them with the community!
MIDI.Plugin.js: Ties together the following frameworks;
MIDI.noteOn(channel, note, velocity, delay);
MIDI.noteOff(channel, note, delay);
MIDI.chordOn(channel, chord, velocity, delay);
MIDI.chordOff(channel, chord, delay);
MIDI.keyToNote = object; // A0 => 21
MIDI.noteToKey = object; // 21 => A0
MIDI.Player.js: Streams the MIDI to the browser.
MIDI.Player.currentTime = integer; // time we are at now within the song.
MIDI.Player.endTime = integer; // time when song ends.
MIDI.Player.playing = boolean; // are we playing? yes or no.
MIDI.Player.loadFile(file, callback); // load .MIDI from base64 or binary XML request.
MIDI.Player.start(); // start the MIDI track (you can put this in the loadFile callback)
MIDI.Player.resume(); // resume the MIDI track from pause.
MIDI.Player.pause(); // pause the MIDI track.
MIDI.Player.stop(); // stops all audio being played, and resets currentTime to 0.
Callback whenever a note is played;
MIDI.Player.removeListener(); // removes current listener.
MIDI.Player.addListener(function(data) { // set it to your own function!
var now = data.now; // where we are now
var end = data.end; // time when song ends
var channel = data.channel; // channel note is playing on
var message = data.message; // 128 is noteOff, 144 is noteOn
var note = data.note; // the note
var velocity = data.velocity; // the velocity of the note
// then do whatever you want with the information!
});
Smooth animation, interpolates between onMidiEvent calls;
MIDI.Player.clearAnimation(); // clears current animation.
MIDI.Player.setAnimation(function(data) {
var now = data.now; // where we are now
var end = data.end; // time when song ends
var events = data.events; // all the notes currently being processed
// then do what you want with the information!
});
Color.js: Color conversions, music isn’t complete without!
Color.Space(0xff0000, "HEX>RGB>HSL");
DOMLoader.script.js: Loads scripts in synchronously, or asynchronously.
