Nikita Tang - President
SEAS 2022, Financial Engineering Major, Computer Science Minor
• Nikita has been with Columbia China Dance since Fall of 2018.
• Nikita practiced rhythmic gymnastics competitively for 10+ years and was a US National Elite Team Member. She started Chinese dance at age 16 and performed at many festivals, senior centers, and schools as well as won champion at national and international competitions.
Dance offers me something more than just the technical challenge found in rhythmic gymnastics; it includes an emotional and spiritual aspect that allows me to really feel myself and immerse myself into my surroundings. The way I feel when the music comes on and my body takes over is amazing and allows me to experience freedom from the stress and work of my daily life. Dance is more than just a hobby to me, it is a world where I feel belonged, a family where unbreakable bonds are created. Come join Columbia China Dance’s family!!!
Asteria Liu - Vice President and Publicity Chair
Barnard 2022, Comparative Literature and Film Studies Major
• Asteria has been with Columbia China Dance since Fall of 2018.

 It speaks out the unique beauty to the public through its variously artistic expressions and aesthetic appreciation. To me, dancing truly helps establish a wonderful balance between work and leisure. My time at Columbia China Dance not only enriches my college experience but also makes it possible for me to discover more people who share the same interest as I do.
Amber Zhao - Publicity Chair and Secretary
SEAS 2021, Earth and Environmental Engineering Major, Premed
• Amber has been with Columbia China Dance since Spring 2019.
• Amber practiced Chinese dance from age 4-16 with a number of dance theaters, and started dancing again at 20.
I always enjoyed Chinese Dance as a kid because it allowed me to connect with other kids my age who I shared a similar background with—something that was rare for me at the time. Now, I enjoy dancing because it allows me to connect with my culture and heritage, as well as share the beauty of Chinese culture with my community.
Olivia Gong - Treasurer
Barnard 2022, Economics and Math Major, Chemistry Minor
• Olivia has been with Columbia China Dance since the Fall of 2018.
• Olivia has been dancing since the age of 3 and over the years she has learned a variety of styles including Ballet, Jazz, Lyrical, Tap, and Chinese Dance.
I started dancing at a very young age and I was giving multiple opportunities to stop dancing throughout my childhood, but for some reason I always would return to it. Dance has always been there and I have made some of my longest lasting friendships through dancing. Dance has definitely become more than just movement or expression, it is a lifestyle that I have come to know, love, and miss—especially since starting college I have not been able to dance as much as I used to. Through Chinese dance I have been able to further embrace and learn about my cultural heritage as well as spread the beauty of Asian art within the community.

The BJP parliamentarian shared an Instagram story hilariously explaining how sleeplessness works and the cure for it through a relatable meme featuring a minion.
The story, in which she captions, “Please…” reads, “Legend says that if you can’t sleep, it’s because you’re in someone’s dream. So if everyone could stop dreaming about me, that would be great (sic).”
Irani had also posted a video featuring the minions on the occasion of the Children’s Day. The video features two minions that are named after her and her husband Zubin, captioned, “This children’s day, say thank you to the ‘Zubin’ in your life who keeps the child in you alive (sic).
It seems the minister likes the minions that she features them often in her posts.

SmartHeat® & Calibration Each cartridge or tip is equipped with a self-regulating heater which ‘senses’ its own temperature and tightly maintains its pre-set idle temperature for the life of the heater-tip; all controlled by OK International’s proprietary SmartHeat® Technology. The tip temperature is determined by the inherent metallurgical properties of the heater; no external adjustment or equipment is required. The power delivered to the tip automatically varies in direct response to the thermal load. This eliminates spikes and transients associated with electrically switched elements found in conventional soldering irons. Please feel free to contact your OK International representative with any questions.

Overview
Action Mailer allows you to send email from your application using a mailer model and views.
Mailer Models
To use Action Mailer, you need to create a mailer model.
$ rails generate mailer Notifier
The generated model inherits from ApplicationMailer
which in turn inherits from Base
. A mailer model defines methods used to generate an email message. In these methods, you can setup variables to be used in the mailer views, options on the mail itself such as the :from
address, and attachments.
class ApplicationMailer < ActionMailer::Base
default from<EMAIL_ADDRESS>layout 'mailer'
end
class NotifierMailer < ApplicationMailer
default from<EMAIL_ADDRESS>return_path<EMAIL_ADDRESS>def welcome(recipient)
@account = recipient
mail(to: recipient.email_address_with_name,
bcc<EMAIL_ADDRESS>"Order Watcher<EMAIL_ADDRESS>end
end
Within the mailer method, you have access to the following methods:
-
attachments[]=
- Allows you to add attachments to your email in an intuitive manner;attachments['filename.png'] = File.read('path/to/filename.png')
-
attachments.inline[]=
- Allows you to add an inline attachment to your email in the same manner asattachments[]=
-
headers[]=
- Allows you to specify any header field in your email such asheaders['X-No-Spam'] = 'True'
. Note that declaring a header multiple times will add many fields of the same name. Read #headers doc for more information. -
headers(hash)
- Allows you to specify multiple headers in your email such asheaders({'X-No-Spam' => 'True', 'In-Reply-To' =><EMAIL_ADDRESS>-
#mail - Allows you to specify email to be sent.
The hash passed to the mail method allows you to specify any header that a Mail::Message
will accept (any valid email header including optional fields).
The #mail method, if not passed a block, will inspect your views and send all the views with the same name as the method, so the above action would send the welcome.text.erb
view file as well as the welcome.html.erb
view file in a multipart/alternative
email.
If you want to explicitly render only certain templates, pass a block:
mail(to: user.email) do |format|
format.text
format.html
end
The block syntax is also useful in providing information specific to a part:
mail(to: user.email) do |format|
format.text(content_transfer_encoding: "base64")
format.html
end
Or even to render a special view:
mail(to: user.email) do |format|
format.text
format.html { render "some_other_template" }
end
Mailer views
Like Action Controller, each mailer class has a corresponding view directory in which each method of the class looks for a template with its name.
To define a template to be used with a mailer, create an .erb
file with the same name as the method in your mailer model. For example, in the mailer defined above, the template at app/views/notifier_mailer/welcome.text.erb
would be used to generate the email.
Variables defined in the methods of your mailer model are accessible as instance variables in their corresponding view.
Emails by default are sent in plain text, so a sample view for our model example might look like this:
Hi <%= @account.name %>,
Thanks for joining our service! Please check back often.
You can even use Action View helpers in these views. For example:
You got a new note!
<%=<EMAIL_ADDRESS>length: 25) %>
If you need to access the subject, from or the recipients in the view, you can do that through message object:
You got a new note from <%= message.from %>!
<%=<EMAIL_ADDRESS>length: 25) %>
Generating URLs
URLs can be generated in mailer views using url_for
or named routes. Unlike controllers from Action Pack, the mailer instance doesn’t have any context about the incoming request, so you’ll need to provide all of the details needed to generate a URL.
When using url_for
you’ll need to provide the :host
, :controller
, and :action
:
<%= url_for(host: "example.com", controller: "welcome", action: "greeting") %>
When using named routes you only need to supply the :host
:
<%= users_url(host: "example.com") %>
You should use the named_route_url
style (which generates absolute URLs) and avoid using the named_route_path
style (which generates relative URLs), since clients reading the mail will have no concept of a current URL from which to determine a relative path.
It is also possible to set a default host that will be used in all mailers by setting the :host
option as a configuration option in config/application.rb
:
config.action_mailer. = { host: "example.com" }
You can also define a default_url_options
method on individual mailers to override these default settings per-mailer.
By default when config.force_ssl
is true
, URLs generated for hosts will use the HTTPS protocol.
Sending mail
Once a mailer action and template are defined, you can deliver your message or defer its creation and delivery for later:
NotifierMailer.welcome(User.first).deliver_now # sends the email
mail = NotifierMailer.welcome(User.first) # => an ActionMailer::MessageDelivery object
mail.deliver_now # generates and sends the email now
The MessageDelivery
class is a wrapper around a delegate that will call your method to generate the mail. If you want direct access to the delegator, or Mail::Message
, you can call the #message method on the MessageDelivery
object.
NotifierMailer.welcome(User.first). # => a Mail::Message object
Action Mailer is nicely integrated with Active Job so you can generate and send emails in the background (example: outside of the request-response cycle, so the user doesn’t have to wait on it):
NotifierMailer.welcome(User.first).deliver_later # enqueue the email sending to Active Job
Note that deliver_later
will execute your method from the background job.
You never instantiate your mailer class. Rather, you just call the method you defined on the class itself. All instance methods are expected to return a message object to be sent.
Multipart Emails
Multipart messages can also be used implicitly because Action Mailer will automatically detect and use multipart templates, where each template is named after the name of the action, followed by the content type. Each such detected template will be added to the message, as a separate part.
For example, if the following templates exist:
-
signup_notification.text.erb
-
signup_notification.html.erb
-
signup_notification.xml.builder
-
signup_notification.yml.erb
Each would be rendered and added as a separate part to the message, with the corresponding content type. The content type for the entire message is automatically set to multipart/alternative
, which indicates that the email contains multiple different representations of the same email body. The same instance variables defined in the action are passed to all email templates.
Implicit template rendering is not performed if any attachments or parts have been added to the email. This means that you’ll have to manually add each part to the email and set the content type of the email to multipart/alternative
.
Attachments
Sending attachment in emails is easy:
class NotifierMailer < ApplicationMailer
def welcome(recipient)
['free_book.pdf'] = File.read('path/to/file.pdf')
mail(to: recipient, subject: "New account information")
end
end
Which will (if it had both a welcome.text.erb
and welcome.html.erb
template in the view directory), send a complete multipart/mixed
email with two parts, the first part being a multipart/alternative
with the text and HTML email parts inside, and the second being a application/pdf
with a Base64 encoded copy of the file.pdf book with the filename free_book.pdf
.
If you need to send attachments with no content, you need to create an empty view for it, or add an empty body parameter like this:
class NotifierMailer < ApplicationMailer
def welcome(recipient)
['free_book.pdf'] = File.read('path/to/file.pdf')
mail(to: recipient, subject: "New account information", body: "")
end
end
You can also send attachments with html template, in this case you need to add body, attachments, and custom content type like this:
class NotifierMailer < ApplicationMailer
def welcome(recipient)
["free_book.pdf"] = File.read("path/to/file.pdf")
mail(to: recipient,
subject: "New account information",
content_type: "text/html",
body: "Hello there")
end
end
Inline Attachments
You can also specify that a file should be displayed inline with other HTML. This is useful if you want to display a corporate logo or a photo.
class NotifierMailer < ApplicationMailer
def welcome(recipient)
.inline['photo.png'] = File.read('path/to/photo.png')
mail(to: recipient, subject: "Here is what we look like")
end
end
And then to reference the image in the view, you create a welcome.html.erb
file and make a call to image_tag
passing in the attachment you want to display and then call url
on the attachment to get the relative content id path for the image source:

Please Don't Cringe

<%= image_tag attachments['photo.png'].url -%>
As we are using Action View’s image_tag
method, you can pass in any other options you want:

Please Don't Cringe

<%= image_tag attachments['photo.png'].url, alt: 'Our Photo', class: 'photo' -%>
Observing and Intercepting Mails
Action Mailer provides hooks into the Mail observer and interceptor methods. These allow you to register classes that are called during the mail delivery life cycle.
An observer class must implement the :delivered_email(message)
method which will be called once for every email sent after the email has been sent.
An interceptor class must implement the :delivering_email(message)
method which will be called before the email is sent, allowing you to make modifications to the email before it hits the delivery agents. Your class should make any needed modifications directly to the passed in Mail::Message
instance.
Default Hash
Action Mailer provides some intelligent defaults for your emails, these are usually specified in a default method inside the class definition:
class NotifierMailer < ApplicationMailer
default sender<EMAIL_ADDRESS>end
You can pass in any header value that a Mail::Message
accepts. Out of the box, Base
sets the following:
-
mime_version: "1.0"
-
charset: "UTF-8"
-
content_type: "text/plain"
-
parts_order: [ "text/plain", "text/enriched", "text/html" ]
parts_order
and charset
are not actually valid Mail::Message
header fields, but Action Mailer translates them appropriately and sets the correct values.
As you can pass in any header, you need to either quote the header as a string, or pass it in as an underscored symbol, so the following will work:
class NotifierMailer < ApplicationMailer
default 'Content-Transfer-Encoding' => '7bit',
content_description: 'This is a description'
end
Finally, Action Mailer also supports passing Proc
and Lambda
objects into the default hash, so you can define methods that evaluate as the message is being generated:
class NotifierMailer < ApplicationMailer
default 'X-Special-Header' => Proc.new { my_method }, to: -> { @inviter.email_address }
private
def my_method
'some complex call'
end
end
Note that the proc/lambda is evaluated right at the start of the mail message generation, so if you set something in the default hash using a proc, and then set the same thing inside of your mailer method, it will get overwritten by the mailer method.
It is also possible to set these default options that will be used in all mailers through the .default_options= configuration in config/application.rb
:
config.action_mailer. = { from<EMAIL_ADDRESS>}
Callbacks
You can specify callbacks using before_action
and after_action
for configuring your messages. This may be useful, for example, when you want to add default inline attachments for all messages sent out by a certain mailer class:
class NotifierMailer < ApplicationMailer
before_action :
def welcome
mail
end
private
def
.inline["footer.jpg"] = File.read('/path/to/filename.jpg')
end
end
Callbacks in Action Mailer are implemented using ::AbstractController::Callbacks
, so you can define and configure callbacks in the same manner that you would use callbacks in classes that inherit from ::ActionController::Base
.
Note that unless you have a specific reason to do so, you should prefer using before_action
rather than after_action
in your Action Mailer classes so that headers are parsed properly.
Previewing emails
You can preview your email templates visually by adding a mailer preview file to the .preview_path. Since most emails do something interesting with database data, you’ll need to write some scenarios to load messages with fake data:
class NotifierMailerPreview < ActionMailer::Preview
def welcome
NotifierMailer.welcome(User.first)
end
end
Methods must return a Mail::Message
object which can be generated by calling the mailer method without the additional deliver_now
/ deliver_later
. The location of the mailer previews directory can be configured using the .preview_path option which has a default of test/mailers/previews
:
config.action_mailer.preview_path = "#{Rails.root}/lib/mailer_previews"
An overview of all previews is accessible at http://localhost:3000/rails/mailers
on a running development server instance.
Previews
can also be intercepted in a similar manner as deliveries can be by registering a preview interceptor that has a previewing_email
method:
class CssInlineStyler
def self.previewing_email( )
# inline CSS styles
end
end
config.action_mailer.preview_interceptors :css_inline_styler
Note that interceptors need to be registered both with .register_interceptor and register_preview_interceptor
if they should operate on both sending and previewing emails.
Configuration options
These options are specified on the class level, like ActionMailer::Base.raise_delivery_errors = true
-
default_options
- You can pass this in at a class level as well as within the class itself as per the above section. -
.logger - the logger is used for generating information on the mailing run if available. Can be set to
nil
for no logging. Compatible with both Ruby’s ownLogger
and Log4r loggers. -
smtp_settings
- Allows detailed configuration for:smtp
delivery method:-
:address
- Allows you to use a remote mail server. Just change it from its default “localhost” setting. -
:port
- On the off chance that your mail server doesn’t run on port 25, you can change it. -
:domain
- If you need to specify a HELO domain, you can do it here. -
:user_name
- If your mail server requires authentication, set the username in this setting. -
:password
- If your mail server requires authentication, set the password in this setting. -
:authentication
- If your mail server requires authentication, you need to specify the authentication type here. This is a symbol and one of:plain
(will send the password Base64 encoded),:login
(will send the password Base64 encoded) or:cram_md5
(combines a Challenge/Response mechanism to exchange information and a cryptographic Message Digest 5 algorithm to hash important information) -
:enable_starttls_auto
- Detects if STARTTLS is enabled in your SMTP server and starts to use it. Defaults totrue
. -
:openssl_verify_mode
- When using TLS, you can set how OpenSSL checks the certificate. This is really useful if you need to validate a self-signed and/or a wildcard certificate. You can use the name of an OpenSSL verify constant ('none'
or'peer'
) or directly the constant (OpenSSL::SSL::VERIFY_NONE
orOpenSSL::SSL::VERIFY_PEER
).:ssl/:tls
Enables the SMTP connection to use SMTP/TLS (SMTPS: SMTP over direct TLS connection)
-
-
sendmail_settings
- Allows you to override options for the:sendmail
delivery method.-
:location
- The location of the sendmail executable. Defaults to/usr/sbin/sendmail
. -
:arguments
- The command line arguments. Defaults to-i
with-f sender@address
added automatically before the message is sent.
-
-
file_settings
- Allows you to override options for the:file
delivery method.-
:location
- The directory into which emails will be written. Defaults to the applicationtmp/mails
.
-
-
.raise_delivery_errors - Whether or not errors should be raised if the email fails to be delivered.
-
.delivery_method - Defines a delivery method. Possible values are
:smtp
(default),:sendmail
,:test
, and:file
. Or you may provide a custom delivery method object e.g.MyOwnDeliveryMethodClass
. See the Mail gem documentation on the interface you need to implement for a custom delivery agent. -
.perform_deliveries - Determines whether emails are actually sent from Action Mailer when you call
.deliver
on an email message or on an Action Mailer method. This is on by default but can be turned off to aid in functional testing. -
deliveries
- Keeps an array of all the emails sent out through the Action Mailer withdelivery_method :test
. Most useful for unit and functional testing. -
.deliver_later_queue_name - The name of the queue used with
deliver_later
. Defaults tomailers
.

Instance Method Details
#attachments
Allows you to add attachments to an email, like so:
mail. ['filename.jpg'] = File.read('/path/to/filename.jpg')
If you do this, then Mail will take the file name and work out the mime type. It will also set the Content-Type, Content-Disposition, Content-Transfer-Encoding and encode the contents of the attachment in Base64.
You can also specify overrides if you want by passing a hash instead of a string:
mail. ['filename.jpg'] = {mime_type: 'application/gzip',
content: File.read('/path/to/filename.jpg')}
If you want to use encoding other than Base64 then you will need to pass encoding type along with the pre-encoded content as Mail doesn’t know how to decode the data:
file_content = SpecialEncode(File.read('/path/to/filename.jpg'))
mail. ['filename.jpg'] = {mime_type: 'application/gzip',
encoding: 'SpecialEncoding',
content: file_content }
You can also search for specific attachments:
# By Filename
mail. ['filename.jpg'] # => Mail::Part object or nil
# or by index
mail. [0] # => Mail::Part (first attachment)
# File 'actionmailer/lib/action_mailer/base.rb', line 702
def if @_mail_was_called LateAttachmentsProxy.new(@_message. ) else @_message. end end
#default_i18n_subject(interpolations = {}) (private)
Translates the subject
using ::Rails
I18n class under [mailer_scope, action_name]
scope. If it does not find a translation for the subject
under the specified scope it will default to a humanized version of the action_name
. If the subject has interpolations, you can pass them through the interpolations
parameter.
# File 'actionmailer/lib/action_mailer/base.rb', line 878
def default_i18n_subject(interpolations = {}) # :doc: mailer_scope = self.class.mailer_name.tr("/", ".") I18n.t(:subject, interpolations.merge(scope: [mailer_scope, action_name], default: action_name.humanize)) end
#headers(args = nil)
Allows you to pass random and unusual headers to the new Mail::Message
object which will add them to itself.
headers['X-Special-Domain-Specific-Header'] = "SecretValue"
You can also pass a hash into headers of header field names and values, which will then be set on the Mail::Message
object:
headers 'X-Special-Domain-Specific-Header' => "SecretValue",
'In-Reply-To' => incoming.
The resulting Mail::Message
will have the following in its header:
X-Special-Domain-Specific-Header: SecretValue
Note about replacing already defined headers:
-
subject
-
sender
-
from
-
to
-
cc
-
bcc
-
reply-to
-
orig-date
-
message-id
-
references
Fields can only appear once in email headers while other fields such as X-Anything
can appear multiple times.
If you want to replace any header which already exists, first set it to nil
in order to reset the value otherwise another field will be added for the same header.
# File 'actionmailer/lib/action_mailer/base.rb', line 664
def headers(args = nil) if args @_message.headers(args) else @_message end end
#mail(headers = {}, &block)
The main method that creates the message and renders the email templates. There are two ways to call this method, with a block, or without a block.
It accepts a headers hash. This hash allows you to specify the most used headers in an email message, these are:
-
:subject
- The subject of the message, if this is omitted, Action Mailer will ask the Rails I18n class for a translated:subject
in the scope of[mailer_scope, action_name]
or if this is missing, will translate the humanized version of theaction_name
-
:to
- Who the message is destined for, can be a string of addresses, or an array of addresses. -
:from
- Who the message is from -
:cc
- Who you would like to Carbon-Copy on this email, can be a string of addresses, or an array of addresses. -
:bcc
- Who you would like to Blind-Carbon-Copy on this email, can be a string of addresses, or an array of addresses. -
:reply_to
- Who to set the Reply-To header of the email to. -
:date
- The date to say the email was sent on.
You can set default values for any of the above headers (except :date
) by using the .default class method:
class Notifier < ActionMailer::Base
default from<EMAIL_ADDRESS>bcc<EMAIL_ADDRESS>reply_to<EMAIL_ADDRESS>end
If you need other headers not listed above, you can either pass them in as part of the headers hash or use the headers['name'] = value
method.
When a :return_path
is specified as header, that value will be used as the ‘envelope from’ address for the Mail message. Setting this is useful when you want delivery notifications sent to a different address than the one in :from
. Mail will actually use the :return_path
in preference to the :sender
in preference to the :from
field for the ‘envelope from’ value.
If you do not pass a block to the mail
method, it will find all templates in the view paths using by default the mailer name and the method name that it is being called from, it will then create parts for each of these templates intelligently, making educated guesses on correct content type and sequence, and return a fully prepared Mail::Message
ready to call :deliver
on to send.
For example:
class Notifier < ActionMailer::Base
default from<EMAIL_ADDRESS>def welcome
mail(to<EMAIL_ADDRESS>end
end
Will look for all templates at “app/views/notifier” with name “welcome”. If no welcome template exists, it will raise an ::ActionView::MissingTemplate
error.
However, those can be customized:
mail(template_path: 'notifications', template_name: 'another')
And now it will look for all templates at “app/views/notifications” with name “another”.
If you do pass a block, you can render specific templates of your choice:
mail(to<EMAIL_ADDRESS>do |format|
format.text
format.html
end
You can even render plain text directly without using a template:
mail(to<EMAIL_ADDRESS>do |format|
format.text { render plain: "Hello Mikel!" }
format.html { render html: "
Hello Mikel!
".html_safe }
end
Which will render a multipart/alternative
email with text/plain
and text/html
parts.
The block syntax also allows you to customize the part headers if desired:
mail(to<EMAIL_ADDRESS>do |format|
format.text(content_transfer_encoding: "base64")
format.html
end
# File 'actionmailer/lib/action_mailer/base.rb', line 811
def mail(headers = {}, &block) return if @_mail_was_called && headers.blank? && !block # At the beginning, do not consider class default for content_type content_type = headers[:content_type] headers = apply_defaults(headers) # Apply charset at the beginning so all fields are properly quoted .charset = charset = headers[:charset] # Set configure delivery behavior wrap_delivery_behavior!(headers[:delivery_method], headers[: ]) (, headers) # Render the templates and blocks responses = collect_responses(headers, &block) @_mail_was_called = true create_parts_from_responses(, responses) # Setup content type, reapply charset and handle parts order .content_type = set_content_type(, content_type, headers[:content_type]) .charset = charset if .multipart? .body.set_sort_order(headers[:parts_order]) .body.sort_parts! end end
#mailer_name
Returns the name of the mailer object.
# File 'actionmailer/lib/action_mailer/base.rb', line 626
def mailer_name self.class.mailer_name end
#set_content_type(m, user_content_type, class_default) (private)
Used by #mail to set the content type of the message.
It will use the given user_content_type
, or multipart if the mail message has any attachments. If the attachments are inline, the content type will be “multipart/related”, otherwise “multipart/mixed”.
If there is no content type passed in via headers, and there are no attachments, or the message is multipart, then the default content type is used.
# File 'actionmailer/lib/action_mailer/base.rb', line 856
def set_content_type(m, user_content_type, class_default) # :doc: params = m.content_type_parameters || {} case when user_content_type.present? user_content_type when m. if m. .detect(&:inline?) ["multipart", "related", params] else ["multipart", "mixed", params] end when m.multipart? ["multipart", "alternative", params] else m.content_type || class_default end end

Guidance
Information on formula protection funding and how it will be applied in 2017 to 2018 academic year.
This information is for institutions that received formula protection funding ( FPF ) in academic year 2016 to 2017. We will only pay FPF to those institutions that received FPF in 2016 to 2017.
We introduced FPF in academic year 2013 to 2014 to moderate the impact of the funding formula changes. FPF enables institutions to manage and plan for the change to funding per student. We originally committed to providing FPF for 3 years, up to and including academic year 2015 to 2016 and then to review it.
We confirmed in January 2016 that FPF will be phased out over 6 years. We made the first reduction in 2016 to 2017 and the last payments will be made to institutions in 2020 to 2021.
We explain how FPF fits within the 16 to 19 funding formula within our funding guidance books .
The purpose of this information is:
We will pay FPF in 2017 to 2018 on the following principles:
We will calculate FPF as shown in the 4 steps below.
We will bring forward the following values from previous years:
| Figures brought forward from 2016 to 2017 | Institution A | Institution B | Institution C |
|---|---|---|---|
| FPF per student in 2016 to 2017 (A) | £270 | £550 | £60 |
| Reduction in FPF applied in calculating the 2016 to 2017 allocation (B) | £100 | £110 | £90 |
| Number of funded students in 2015 to 2016 (C) | 3000 | 250 | 600 |
We will reduce the 2017 to 2018 FPF per student by the same amount that we used when calculating your 2016 to 2017 FPF (figure B from step 1).
If this gives a figure above zero, that is the FPF per student in 2017 to 2018. If the figure is zero or lower, then no FPF will be paid in 2017 to 2018 or subsequent years.
| Calculation of FPF per student in 2017 to 2018 | Institution A | Institution B | Institution C |
|---|---|---|---|
| FPF per student in 2016 to 2017 (A) | £270 | £550 | £60 |
| Reduction applied in 2016 to 2017 (B) | £100 | £110 | £90 |
| FPF per student in 2017 to 2018 – A-B with a minimum of zero (D) | £170 | £440 | £0 |
We will compare the 2017 to 2018 student numbers to the number of funded students in 2015 to 2016. The student numbers eligible for FPF in 2017 to 2018 will be the lower of these 2 figures.
| Calculation of number of students eligible for FPF in 2017 to 2018 | Institution A | Institution B | Institution C |
|---|---|---|---|
| Number of funded students in 2015 to 2016 (C) | 3000 | 250 | Not applicable – no FPF in 2017 to 2018 |
| Number of students eligible for FPF in 2017 to 2018 (F) | 3000 | 240 | Not applicable – no FPF in 2017 to 2018 |
| Total FPF in 2017 to 2018 – DxF (G) | £510,000 | £105,600 | Not applicable – no FPF in 2017 to 2018 |
We will calculate the total FPF by multiplying the final FPF per student by the eligible student numbers.
| Calculation of total FPF in 2017 to 2018 | Institution A | Institution B | Institution C |
|---|---|---|---|
| FPF per student in 2017 to 2018 (D) | £170 | £440 | Not applicable – no FPF in 2017 to 2018 |
| Number of students eligible for FPF in 2017 to 2018 (F) | 3000 | 240 | Not applicable – no FPF in 2017 to 2018 |
| Total FPF in 2017 to 2018 – DxF (G) | £510,000 | £105,600 | Not applicable – no FPF in 2017 to 2018 |

I have worked on numerous campaigns including several issue campaigns. In 2004, I worked for Coalition for a Better Colorado, a 527 that supported democrats for state house and senate. In 2007, I was campaign manager for Councilwoman Peggy Lehmann, Democrat for Denver City Council. I've donated to the Colorado Democratic Party; Arapahoe County Democratic Party, Jared Polis, Phil Weiser, Jena Griswold, Brittany Petterson, Faith Winter, Jon Singer, Chris Hinds, Melissa Martin, Jason Crow, and Omar Montgomery. I donated to Kayvan Khalatbari (Unaffiliated).

In 2003, I received my BA in Political Science from CU Boulder. I then worked on a series of political campaigns, including several issue campaigns: 2005: passing a school mill levy, 2006: ballot initiative for domestic partnerships in Colorado, 2010: allowing licensed medical marijuana businesses in El Paso County, 2011 to 2020: allowing licensed cannabis businesses in several cities. 2011 to 2016: ran a trade association for licensed cannabis businesses that helped implement licensed and regulated cannabis sales in Colorado, 2018-2020: worked with organizations to serve human trafficking victims and find innovative solutions to reduce human trafficking. 2019-2020: board member of organization dedicated to advocating for consumers.
Colorado has a rare opportunity to discard the intense partisan gamesmanship familiar to the redistricting process. Living in Colorado for most of my life, I remember being frustrated that unnamed parties seemed to be influencing the final outcome. I was relieved that Amendments Y and Z passed with bipartisan support. As Secretary Buescher indicated, this work is historic. As a Coloradan interested in protecting our democratic form of government, I feel a duty to help.
I'm kind and I enjoy people. I'm open and will be proactive about communicating with the other commission members including the Republicans and Independents. I will strive to ensure every person is heard, and issues are fairly resolved. I can be fair and impartial by focusing on the objective criteria that need to be used such as preserving whole communities of interest, and not drawing districts to favor a candidate or party or dilute the electoral influence of racial or language minority groups.
As an attorney, I've been trained to issue spot, identify relevant rules and facts, apply the law to the facts, and make conclusions. The Commission is faced with several difficult priorities to balance. I believe I can help keep the process fair, be proactive and assertive to solve problems, and to be a good listener that incorporates feedback from all participants.

WriteProgramData()
Syntax
Result = WriteProgramData(Program, *Buffer, Size)Description
Writes the data from the buffer to the specified programs input (stdin).
Parameters
Program The program to use. It must have been started before with RunProgram() and the #PB_Program_Write flag. *Buffer The memory buffer to write the data from. The special value #PB_Program_Eof can be used instead of a real memory buffer to make the program receive an EOF (end of file) in its input (which tells the program that there will be no more input). The 'Size' parameter is ignored in this case. After calling WriteProgramData() with this special value, no more input may be written to the program. Size The size to write.
Return value
The number of bytes actually written.

1.1.2. Basic workflow¶
This examples demonstrates a basic workflow using the py-fmas library code.
We start by simply importing the required fmas into the current namespace.
import fmas
If an adequate input file is located within the current working directory, the function read_h5, located in module data_io, can be used to read-in the propagation setting stored in the input file input_file.h5:
glob = fmas.data_io.read_h5('input_file.h5')
Next, the problem specific data structures, given by the computational grid and the propagation model, can be initialized:
grid = fmas.grid.Grid(
t_max = glob.t_max,
t_num = glob.t_num,
z_max = glob.z_max,
z_num = glob.z_num)
model = fmas.models.FMAS_S_R(
w = grid.w,
beta_w = glob.beta_w,
n2 = glob.n2,
fR = glob.fR,
tau1 = glob.tau1,
tau2 = glob.tau2)
The provided initial condition, which represents the real-valued optical field can be converted to the complex-valued analytic signal as shown below:
ic = fmas.analytic_signal.AS(glob.E_0t)
Below we implement a user-action function that can be passed to the propagation algorithm. Upon propagation it will evaluated at every \(z\)-step
import numpy as np
def Cp(i, zi, w, uw):
Iw = np.abs(uw)**2
return np.sum(Iw[w>0]/w[w>0])
Next, we initialzize the \(z\)-propagation algorithm, given by the Runge-Kutta in the interaction picture (RK4IP) method, set the initial condition, and perform \(z\)-propagation:
solver = fmas.solver.IFM_RK4IP(
model.Lw, model.Nw,
user_action = Cp)
solver.set_initial_condition(
grid.w, ic.w_rep)
solver.propagate(
z_range = glob.z_max,
n_steps = glob.z_num,
n_skip = glob.z_skip)
After the propagation algorithm has terminated, the generated simulation data can be stored within an output file in HDF5-format. Therefore, the data is organized as dictionary with custom keys for the stored data objects, which is then passed to the function save_h5 implemented in module data_io:
res = {
"t": grid.t,
"z": solver.z,
"w": solver.w,
"u": solver.utz,
"Cp": solver.ua_vals}
fmas.data_io.save_h5('out_file.h5', **res)
A simple plot of the generated data can be obtained using convenience functions implemented in module tools:
fmas.tools.plot_evolution(
solver.z, grid.t, solver.utz,
t_lim = (-500,2200), w_lim = (1.,4.))
Total running time of the script: ( 0 minutes 34.082 seconds)


Please follow each step completely. Use the other lessons and resources (Mozilla Developer Network) to help you. You may also get help from your classmates. Kevin and Adam will be able to help, so if you get stuck, raise your hand to let them know.

Private, personal, elder care and assistanceImproving elder wellness at home using artificial intelligence to sense, respond, inform, understand, plan, predict, and act. |
Age-At-Home provides personal, local, artificial intelligence to assist and interact with both the elderly and their community of family, friends, and care-givers.
Utilizing open-source software from Home Assistant and the LINUX Foundation's Open Horizon, the system provides distributed and decentralized edge AI to sense and respond to end-user activities and interactions.
While many approaches to assisting the elderly require devices to be worn or smartphone apps and sending data to the Cloud, Age-At-Home is a pervasive, but not invasive, aggregation of your Internet-of-Things (IOT) and "smart" devices and their capabilities. Analyzing data, producing information, and sensing and responding in the home; disclosing only your selected information to friends, family, or care-takers.
Our objective is to improve the lives of people, starting with the elderly, by sensing and responding in the home and leveraging communities of shared interest to improve AI's ability to understand, learn, plan, and interact.
Age-At-Home interfaces with Internet-of-Things (IoT) devices, including cameras, microphones, speakers and utilizes artificial intelligence to:

This method will query the account store and operates under the following, undocumented assumptions (as of iOS 6.0):
If the user has not authenticated with Facebook on their device, the account store will return
nil
when requesting Facebook accounts.If the user has authenticated with Facebook, but we are not yet authorized to use the account, the account store will return an empty array (except in the simulator, which will return the configured account as the array’s only member).
If the user has authenticated with Facebook and we are already authorized to use the account, the account store will return an array with the authorized account as the only entry.
Unfortunately, the above assumptions are the only way to discover what we need to know and quite likely will break in future releases of iOS 6. For that reason, one should keep a close eye on this method to ensure support is maintained throughout future releases.
TODO Write unit tests for this method.

Musical Chairs
问题描述 :
In the traditional game of Musical Chairs, N + 1 children run around N chairs (placed in a circle) as long as music is playing. The moment the music stops, children run and try to sit on an available chair.  The last child to sit is the winner.
In an attempt to create a similar game on these days’ game consoles, you modify the game in the following manner: N Children are seated on N chairs arranged around a circle. The chairs are numbered from 1 to N . Your program pre-selects a positive number D . The program starts going in circles counting the children starting with the first chair. Once the count reaches D , that child leaves the game, removing his/her chair. The program starts counting again, beginning with the next chair in the circle. The last child remaining in the circle is the winner.

Once the count reaches D , that child leaves the game, removing his/her chair. The program starts counting again, beginning with the next chair in the circle. The last child remaining in the circle is the winner.
For example, consider the game illustrated in the figure above for N = 5 and D = 3 . In the figure, the dot indicates where counting starts and × indicates the child leaving.  Child #1 is the second child to leave and counting restart with child #2 resulting in child #5 leaving. Child #2 is the last to leave, and child #4 is the winner. Write a program to determine the winning child given both N and D .
输入:
Your program will be tested on one or more test cases. Each test case specifies two positive integers N and D on a single line, separated by one or more spaces, where N, D < 1, 000, 000 .
The last line of the input file contains two 0′s and is not part of the test cases.

可以用公式。主要为了说明动态规划，如果要打表的话，这种方法也是较简单和高效的
代码不错，赞一个！
网站不错
正是我要找的，适合新手
能不能说一下tmp数组和solve都是干嘛的？
很好的思路，可以借鉴
.net中char类型不是两个字节么
很好的思路，可以借鉴
遍历了所有的情况(2^n)，tmp数组就是由当前遍历的状态s推算出的
辛苦了，顶
失误失误，转载错了。已经改正，抱歉。
题目和代码都不一样好吗！！！搞错了
对，就是把这32位当成一个长度为32的数
不错的代码！

For the fig-swirl: Melt butter over medium heat in a saucepan. Add brown sugar and stir to dissolve. Halve all of the figs and toss in the saucepan with water and lemon juice. Cook over medium heat, stirring frequently, until you have a chunky-jammy mixture. Add salt with one or two stirs, set aside and let cool completely.
Ice cream: In a small pot over medium heat, combine milk, and granulated sugar until sugar is completely dissolved and the milk is just barely lukewarm. Whisk in the egg yolks. Set mixture in the fridge and wait until the fig mixture is cooled.
Using an ice cream machine, pour liquids into the frozen basin and process according to manufacturer instructions, i.e., let spin and thicken for 20 minutes before adding mascarpone, fig jam mixture, and the nuts. Continue to process for +/- 10 minutes. Pour semi-frozen mixture into a pyrex dish or glass tupperware. Freeze for at least two hours before serving.

Content Density can be maintained app-wide using the ContentDensityService
, and components can
subscribe to a BehaviorSubject
managed by the service and use that to handle changes to the content
density. Before using it, you should add ContentDensityService
to providers array to
AppModule
, or other root module in your application.
Note that many components only come in one size, and others (such as the button below) only have
compact
and cozy
sizes, so setting the size to condensed
will have same effect as compact.
All components that have content density options will first check to see if the developer has provided a
compact
input value, and if not, it will then refer to the value set in the
ContentDensityService
.
