Make these light-as-a-feather cupcakes with their pretty pink decoration for someone you love.
For the cakes, preheat the oven to 180C/350F/Gas 4. Sit 12 paper cases in a muffin tray.
Beat the butter and sugar in a bowl until pale and creamy. Add the eggs, one at a time, and beat until well combined.
Fold the flour, raspberries and passion fruit pulp into the mixture until almost smooth. If the mixture looks too stiff, add a little milk, as necessary.
Divide the mixture among the paper cases then bake for 20 minutes. Remove from the oven and set aside to cool in the tin for 10 minutes. Turn the cakes out onto a wire rack and set aside until completely cooled.
For the icing, using an electric whisk, cream the icing sugar and butter together until light and fluffy. Whisk in the vanilla pod seeds and food colouring. Gradually whisk in enough milk to form a smooth paste.
Spoon the icing into a piping bag with a large star-shaped nozzle and pipe the icing over the cake. Sprinkle over the hundreds and thousands.

users, and are constants included for normalization. In the
iterative metric method of solving fixed boundary equilibrium problem, we
first construct a coordinates transformation

for that surface coincides with the last closed flux surface), then
solve the GS equation in
coordinate system to get the value
of at grid points, and finally adjust the value of

usually does not satisfy the constraint given by Eq. (463) since we do
not use any information of Eq. (463) in the above steps. Now comes the
question: how to make the transformation obtained above satisfy the constraint

Dear friend, I am contacting you from London. My name is Jim Owens. A Top Management Official of one of the finance Corporation in London.Please do not get upset as to how I got your contact. I got your email Contact from the Internet. I sincerely advise that you calm down to read below propos thoroughly and thereafter decide if we can do the business together. It is no setup or one of these hoaxes from Africa. This is a real deal and I mean every word I speak here. A US citizen, Mr. Norman Anderson has been a customer of my bank since 1988. He opens a domiciliary account with us in June 1988. The said bank account, which is at the moment in dormant, is in UK pounds sterling and has credit balance of 29.3M pounds. Last transaction carried on the account dates back to September 15,1999. I have been the account ownerâ€™s confidant and account officer until above date when he was last seen in the bank. And since this time Mr. Anderson has not been to the bank nor sent in cheque for clearing. This became a source of worry to me and prompted my personal investigation as to where about and business activity of this customer. Result of my investigation revealed that he was into oil bunkering and operated within West and Central Africa sub-regions. Further investigation proved that he was one of the victims of November 1999 raid of illegal oil bunkering merchants in Malabo Island of Equatorial Guinea. However, I continued my investigation and further discovered that a UK telephone number mentioned in our bank information form, which he filled when the said bank account was established, belong to hotel in London. This is a clear indication that he probably has fed my bank with false information to protect his illegal oil deals. I have not disclosed these findings to anyone else except this message to you. After a careful study of the account file and available data to me, I have packaged a good deal as follows; and will wish to carry it out with you. My Dear Friend, the deal here is that the money in this account will be approved and remitted to any foreigner who shows up as relation to Mr. Anderson provided such person has correct information to the account. I have such needed information and will hand it over to you as soon as we commence the transaction. I will source all necessary documents and forward them to you for Direct submission to the bank. With my position as the foreign operations manager we will quietly remove this money from the bank without hitches. I donâ€™t have any problem in regularizing all necessary documents and transferring the credit balance of the said account to your nominated bank account in overseas, but the problem is trust. I have spent months in trying to get an overseas reliable contact. It is worthy to note that people are unreliable these days and even derive joy in telling lies. On this ground I request youâ€™re unreserved but sincere cooperation devoid of greed in carrying out this transaction so that no one amongst both of us shall defraud each other at the end. I am prepared to split at 60%---40% for you, provided that mine (60%) will be intact at the end. Waits for your expected co-operation. Reply and send your Address, tel and fax number. Best regards, Jim Owens ---------------------------------------- hry.atlas.cz - Svìtovì proslulá karetní hra Poker Texas Hold´em online


- "contains" matching (not just "starts with"),
- Resharper-style "camel-humps" (PIC for PageIndexChanged).
You toggle in with control-alt-space, and it stops the auto-complete. It prevents auto-selecting the wrong thing when you name a new class or method that's close to something that's already in scope.
Very handy in TDD tests, because the classes and methods don't exist until you've written the test.
normal intellisense with autocomplete- press space, and you get CategoryTest. Opps!
Consume first (Ctrl-Alt-Space): no auto-select (you have to click from the dropdown), and the suggestions includes "Category" even through it doesn't (yet) exist.
It then provides "Generate class" hints, and a "Generate Other" dialogue for more control.

What is new in Ring 1.2?¶
In this chapter we will learn about the changes and new features in Ring 1.2 release.
List of changes and new features¶
Ring 1.2 comes with many new features
- New Functions
- Better Functions
- Better Ring Notepad
- Better RingQt
- Objects Library for RingQt
- RingLibCurl
- Better Call Command
- Using NULL instead of NULLPointer()
- Display Warnings Option
- Better Quality
New Functions¶
- PtrCmp() Function is a new function that compare between C pointers like the GUI objects.
- PrevFileName() Function is added to return the previous active source file name.
- RingVM_CFunctionsList() Function is added to return a list of functions written in C.
- RingVM_FunctionsList() Function is added to return a list of functions written in Ring.
- RingVM_ClassesList() Function is added to return a list of Classes.
- RingVM_PackagesList() Function is added to return a list of Packages.
- RingVM_MemoryList() Function is added to return a list of Memory Scopes and Variables.
- RingVM_CallList() Function is added to return a list of the functions call list.
- RingVM_FilesList() Function is added to return a list of the Ring Files.
Example:
fp = fopen("ptrcmp.ring","r")
fp2 = fp
fp3 = fopen("ptrcmp.ring","r")
see ptrcmp(fp,fp2) + nl
see ptrcmp(fp,fp3) + nl
fclose(fp)
fclose(fp3)
Output:
1
0
Also we can compare between them using the ‘=’ operator
Example:
fp = fopen("ptrcmp2.ring","r")
fp2 = fopen("ptrcmp2.ring","r")
fp3 = fp
see fp = fp2
see nl
see fp = fp3
fclose(fp)
fclose(fp2)
Output:
0
1
Example:
The next function in stdlib.ring uses the PrevFileName() to know if the file of the caller function is the main source file of the program or not.
Func IsMainSourceFile
if PrevFileName() = sysargv[2]
return true
ok
return false
Better Functions¶
The find() function is updated to support searching in lists using C pointers like GUI Objects.
The type() function is updated to display the C pointers types (like the GUI Object Class Name).
Better Ring Notepad¶
The Ring Notepad will save the current line number of opened files to be restored when we switch between files.
Also Ring Notepad will ask the user to save the file if the file content is changed when the user switch between files.
Better RingQt¶
RingQt classes are updated to include methods to get events (The code that will be executed when an event is fired). This is necessary to enable/disable events for some time or to get the events information.
For example the next code disable an event then call a method then enable the event again.
cEvent = oView.oListResult.getCurrentItemChangedEvent()
oView.oListResult.setCurrentItemChangedEvent("")
FindValueAction() # Call Method while an event is disabled
oView.oListResult.setCurrentItemChangedEvent(cEvent)
Also the QAllEvents class is updated where we can set the output from the event function to be true or false using a new method added to the class called setEventOutput.
Load "guilib.ring"
MyApp = New qApp {
win = new qWidget() {
setwindowtitle("Hello World")
setGeometry(100,100,370,250)
lineedit1 = new qlineedit(win) {
setGeometry(10,100,350,30)
setinputmask("9999;_")
oFilter = new qallevents(lineedit1)
oFilter.setfocusoutEvent("pMove()")
installeventfilter(oFilter)
}
lineedit2 = new qlineedit(win) {
setGeometry(10,150,350,30)
}
show()
}
exec()
}
func pMove
win.setWindowTitle("xxxx")

Objects Library for RingQt¶
Ring 1.2 comes with the Objects library for RingQt applications. Instead of using global variables for windows objects and connecting events to objects using the object name, the Objects Library will manage the GUI objects and will provide a more natural API to quickly create one or many windows from the same class and the library provide a way to quickly set methods to be executed when an event is fired. Also the library provide a natural interface to quickly use the parent or the caller windows from the child or sub windows.
The Objects Library is designed to be used with the MVC Design Pattern.
The Objects Library is merged in RingQt so you can use it directly when you use RingQt
Example :
load "guilib.ring"
new qApp {
open_window( :MainWindowController )
exec()
}
class MainWindowController from WindowsControllerParent
oView = new MainWindowView
func SubWindowAction
Open_window( :SubWindowController )
Last_Window().SetParentObject(self)
class MainWindowView from WindowsViewParent
win = new qWidget() {
SetWindowTitle("Main Window")
btnSub = new qPushButton(win) {
setText("Sub Window")
setClickEvent( Method( :SubWindowAction ) )
}
resize(400,400)
}
class SubWindowController from WindowsControllerParent
oView = new SubWindowView
func SetMainWindowTitleAction
Parent().oView.win.SetWindowTitle("Message from the Sub Window")
oView.win.SetWindowTitle("Click Event Done!")
class SubWindowView from WindowsViewParent
win = new qWidget() {
SetWindowTitle("Sub Window")
btnMsg = new qPushButton(win) {
setText("Set Main Window Title")
setClickEvent( Method( :SetMainWindowTitleAction ) )
}
btnClose = new qPushButton(win) {
Move(200,0)
setText("Close")
setClickEvent( Method( :CloseAction ) )
}
resize(400,400)
}
RingLibCurl¶
The LibCurl library is used starting from Ring 1.0 for the Download() and SendEmail() functions implementation. In Ring 1.2 more functions are added to provide a powerful library (RingLibCurl) around LibCurl.
Example:
load "libcurl.ring"
curl = curl_easy_init()
cPostThis = "page=4&Number1=4&Number2=5"
curl_easy_setopt(curl, CURLOPT_URL, "http://localhost/ringapp/index.ring?page=3")
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, cPostThis)
curl_easy_perform(curl)
curl_easy_cleanup(curl)
Better Call Command¶
The Call command is updated to support calling functions from object attributes also (not only variables).
For example the next code from the Stars Fighter Game
cFunc = oself.keypress
call cFunc(oGame,oSelf,Key_Space)
Can be written in one line
call oself.keypress(oGame,oSelf,Key_Space)
Using NULL instead of NULLPointer()¶
We can pass NULL to functions instead of using NULLPointer()
For example the next code from RingLibSDL
SDL_RenderCopy(SDL_ren,tex,NULLPointer(),rect)
Can be written as in the next line
SDL_RenderCopy(SDL_ren,tex,NULL,rect)
Display Warnings Option¶
In Ring 1.2 the Ring compiler is updated to include the Display Warnings option (-w)
Example:
load "stdlib.ring"
load "stdlib.ring"
compiling the program using the Display Warnings option will display the file duplication warning, While without that option the error will pass silent.
This is a warning (not an error) because in large projects you may use the same file more than one time. For example it’s common to start each file with the next code. where the function IsMainSourceFile() is part from the stdlib.ring
load "stdlib.ring"
if IsMainSourceFile()
// Testing
ok
Better Quality¶
Ring 1.2 is more stable, We discovered and fixed more bugs during Ring usage everyday in practical projects. Some functions are optimized to be faster like the SubStr() function. Also the documentation is more better.

Wade Wilson was an average man living a normal life until he was diagnosed with cancer. Not wanting his life to end, he went to a mysterios group who promised him super powers to cure his cancer. He gained super regeneration by being subjected to insanely intense tests and experiments, with the side affect being it completely ruined his face. He decided not to return to his girlfriend, and he ran away from home to become Deadpool, a paid mercernary.
Deadpool often makes vulgar jokes, and tends to break the 4th wall, however, the most notable in the movie is when they begin testsing, and tell him he will become a superhero, he asks that as long as it isn't in a green suit, a jab at Ryan Reynolds previos role as Green Lantern


Queensland to bid to bring Games back to Australia in 2032
SYDNEY: Queensland will launch a bid to bring the Summer Olympics to Australia for the third time in 2032 if it can get financial support from central and local government, state premier Annastacia Palaszczuk said on Monday.
The bid would be centred on the city of Brisbane and the Gold Coast and Sunshine Coast beach resort areas of the southeast of the state, and take place from July 23 to Aug. 8 2032, she told a news conference.
"This is about so much more than a few weeks of sport," Palaszczuk added in a statement.
"Hosting the 2032 Olympics and Paralympics could be a game-changer and deliver 20 years of accelerated opportunity for our state.
"That's why cabinet has today made the decision to continue working towards securing a Games – and we will continue to work closely with our partners to ensure we receive the financial support we require from all levels of government.
"There's more work to do to ensure we are in a position to put a compelling case to the International Olympic Committee."
Australia hosted the Olympics in 1956 in Melbourne and again in Sydney in 2000 but Brisbane's bid to bring the Games to Queensland in 1992 lost out to Barcelona.
The state has twice hosted the Commonwealth Games - in Brisbane in 1982 and the Gold Coast last year - and Palaszczuk estimated that up to 80per cent of the venues required to stage the Olympics were already in place or would be temporary.
Australia's Prime Minister Scott Morrison is on record as saying his government would back the bid "all the way" and Palaszczuk said the Olympics could create 130,000 jobs and boost "tourism spending" by AUS$20 million (10.6 million pounds).
"The world's greatest event provides a platform like no other. It's an opportunity to showcase Queensland to the rest of the world," she added.
"Hosting around 11,000 athletes from 206 countries, and an estimated television audience of 3.2 billion people would see the world watching Queensland at its best."
There are indications that rival bids for 2032 may come from Indonesia, India, Spain, Germany, Italy, Britain and Russia, while North and South Korea are investigating a joint proposal to bring the Olympics back to the peninsula.
Tokyo will host the Summer Olympics for the second time next year with Paris locked in for 2024 and a return to Los Angeles for the third time in 2028 already confirmed.

Using the search parameters "busType: 'ice cream', location: 'Oakland CA' ", the unfiltered content returned from the API and output to the console looks like this:
Although the raw data is helpful in demonstrating all business attributes available to you, you need to first convert it into a useable form for access to individual elements. Recall from the previous section that the callback data type requested was JSONP. To get to each business and its attributes within the returned object (and to make pretty formatting), the object is stringified into a JSON string and then parsed into individual JSON objects. Each object represents a single business.
Business attributes can then be displayed on a web page or logged at the console. Below, a "for"loop is used to move through the business objects and print out the desired attributes. Here, we've chosen to display the thumbnail picture of the business and Yelp link, the rating, name, phone number and address. You can see the working version of the code on the next page.
Here are the final results from the command line query, neatly parsed and displayed to output:


8.3. Conditional Expressions
CASE
The standard SQL CASE
expression has two forms.
The “simple” form searches each value
expression from left to right
until it finds one that equals expression
:
CASE expression
WHEN value THEN result
[ WHEN ... ]
[ ELSE result ]
END
The result
for the matching value
is returned.
If no match is found, the result
from the ELSE
clause is
returned if it exists, otherwise null is returned. Example:
SELECT a,
CASE a
WHEN 1 THEN 'one'
WHEN 2 THEN 'two'
ELSE 'many'
END
The “searched” form evaluates each boolean condition
from left
to right until one is true and returns the matching result
:
CASE
WHEN condition THEN result
[ WHEN ... ]
[ ELSE result ]
END
If no conditions are true, the result
from the ELSE
clause is
returned if it exists, otherwise null is returned. Example:
SELECT a, b,
CASE
WHEN a = 1 THEN 'aaa'
WHEN b = 2 THEN 'bbb'
ELSE 'ccc'
END
IF
The IF
function is actually a language construct
that is equivalent to the following CASE
expression:
CASE WHEN condition THEN true_value [ ELSE false_value ] END
-
if
(condition, true_value) Evaluates and returns
true_value
ifcondition
is true, otherwise null is returned andtrue_value
is not evaluated.
-
if
(condition, true_value, false_value) Evaluates and returns
true_value
ifcondition
is true, otherwise evaluates and returnsfalse_value
.
COALESCE
-
coalesce
(value1, value2[, ...]) Returns the first non-null
value
in the argument list. Like aCASE
expression, arguments are only evaluated if necessary.
NULLIF
-
nullif
(value1, value2) Returns null if
value1
equalsvalue2
, otherwise returnsvalue1
.
TRY
-
try
(expression) Evaluate an expression and handle certain types of errors by returning
NULL
.
In cases where it is preferable that queries produce NULL
or default values
instead of failing when corrupt or invalid data is encountered, the TRY
function may be useful. To specify default values, the TRY
function can be
used in conjunction with the COALESCE
function.
The following errors are handled by TRY
:
- Division by zero
- Invalid cast or function argument
- Numeric value out of range
Examples

Use this document to guide your peer-review of other students' research questions.
The art of constructing an analytical research question is a difficult skill to learn, but with persistence and dedication it can be mastered in a short span of time. An analytical research question is not something that can be written in a single sitting. Rather, an analytical research question is the result of a sustained process—a process that requires careful planning, a developed knowledge of your chosen topic, and constant revision. To help you get started, this page provides information about the Types of Questions you can and should ask about a topic and warns you about some common Mistakes to Avoid when composing a good analytical research question.

The server cannot or will not process the request due to an apparent client error (e.g., malformed request syntax, too large size, invalid request message framing, or deceptive request routing).
Indicates that the request could not be processed because of conflict in the request, such as an edit conflict between multiple simultaneous updates.
The server cannot meet the requirements of the Expect request-header field.
The request failed due to failure of a previous request (e.g., a PROPPATCH).
The request was valid, but the server is refusing action. The user might not have the necessary permissions for a resource.
The server was acting as a gateway or proxy and did not receive a timely response from the upstream server.
Indicates that the resource requested is no longer available and will not be available again. This should be used when a resource has been intentionally removed and the resource should be purged. Upon receiving a 410 status code, the client should not request the resource in the future. Clients such as search engines should remove the resource from their indices. Most use cases do not require clients and search engines to purge the resource, and a "404 Not Found" may be used instead.
The server does not support the HTTP protocol version used in the request
The server is unable to store the representation needed to complete the request.
A generic error message, given when an unexpected condition was encountered and no more specific message is suitable.
This code was defined in 1998 as one of the traditional IETF April Fools' jokes, in RFC 2324, Hyper Text Coffee Pot Control Protocol, and is not expected to be implemented by actual HTTP servers. The RFC specifies this code should be returned by teapots requested to brew coffee. This HTTP status is used as an Easter egg in some websites, including Google.com.
The request did not specify the length of its content, which is required by the requested resource.
The resource that is being accessed is locked.
The server detected an infinite loop while processing the request.
A request method is not supported for the requested resource; for example, a GET request on a form that requires data to be presented via POST, or a PUT request on a read-only resource.
The request was directed at a server that is not able to produce a response (for example because a connection reuse).
The client needs to authenticate to gain network access. Intended for use by intercepting proxies used to control access to the network (e.g., "captive portals" used to require agreement to Terms of Service before granting full Internet access via a Wi-Fi hotspot).
The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.
Further extensions to the request are required for the server to fulfill it.
The requested resource could not be found but may be available in the future. Subsequent requests by the client are permissible.
The server either does not recognize the request method, or it lacks the ability to fulfill the request. Usually this implies future availability (e.g., a new feature of a web-service API).
The request is larger than the server is willing or able to process. Previously called "Request Entity Too Large".
Reserved for future use. The original intention was that this code might be used as part of some form of digital cash or micro payment scheme, but that has not happened, and this code is not usually used. Google Developers API uses this status if a particular developer has exceeded the daily limit on requests.
The server does not meet one of the preconditions that the requester put on the request.
The origin server requires the request to be conditional. Intended to prevent "the 'lost update' problem, where a client GETs a resource's state, modifies it, and PUTs it back to the server, when meanwhile a third party has modified the state on the server, leading to a conflict."
The client must first authenticate itself with the proxy.
The client has asked for a portion of the file (byte serving), but the server cannot supply that portion. For example, if the client asked for a part of the file that lies beyond the end of the file. Called "Requested Range Not Satisfiable" previously.
The server is unwilling to process the request because either an individual header field, or all the header fields collectively, are too large.
The server timed out waiting for the request. According to HTTP specifications: "The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time."
The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
The user has sent too many requests in a given amount of time. Intended for use with rate-limiting schemes.
Similar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource. See Basic access authentication and Digest access authentication. 401 semantically means "unauthenticated",i.e. the user does not have the necessary credentials.
A server operator has received a legal demand to deny access to a resource or to a set of resources that includes the requested resource. The code 451 was chosen as a reference to the novel Fahrenheit 451.
The request was well-formed but was unable to be followed due to semantic errors.
The request entity has a media type which the server or resource does not support. For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format.
The client should switch to a different protocol such as TLS/1.0, given in the Upgrade header field.
The URI provided was too long for the server to process. Often the result of too much data being encoded as a query-string of a GET request, in which case it should be converted to a POST request. Called "Request-URI Too Long" previously.
Transparent content negotiation for the request results in a circular reference.
The server was acting as a gateway or proxy and received an invalid response from the upstream server.

Mom of preemie who died pumped breast milk until his due date then donated it
The mother of a premature baby who died at three hours old pumped breast milk for 63 days after – then donated it on her son’s due date.
Sierra Strangfield made the incredible gesture of kindness after losing her boy Samuel to a genetic condition called Trisomy 18, which causes developmental delays.
Samuel was born at 25 weeks on September 5 at a hospital near his family’s home in Neillsville, Wisconsin.
His mother was devastated by his death, but determined to help other sick babies out as best she could.
And she kept pumping until November 7 – the day she had expected to welcome Samuel into the world. Sierra froze her milk as she went along, then donated it all to her local neo-natal intensive care unit.
Writing on Facebook, Sierra explained: ‘When I found out I was pregnant again, I wanted nothing more than to be successful at breastfeeding.
Advertisement Advertisement
‘But when we found out of Samuel’s diagnosis, I knew that was not going to happen.
‘Just another hope that was taken from me.
‘Before Samuel passed, I told myself I would pump my milk to donate.’
Sierra said her older daughter Porter had received donor milk for months after she was born, with those women’s kindness inspiring her to do the same.
She added: ‘I couldn’t save Samuel’s life, but maybe I could save another baby’s life .
‘Pumping is not for the faint of heart. It’s hard.
‘Mentally and physically.

‘Why was I waking up in the middle of the night for this?
‘The other part of me felt it was the only thing connecting me to Samuel here on Earthside. I sure hope he’s proud of me!
‘I pumped for 63 days after his birth. I am not an over supplier by any means- but I did it.
‘And today, his due date, I donated my milk to the NICU milkbanks for the first and last time.

‘Walking through the hallways of the hospital was just another step in healing.And I know, (because I felt him), that Samuel was there with me.’
Sierra’s post was widely shared online, with over a thousand people praising her selfless act of kindness.
She says she has been wowed by the response, and now hopes to raise further awareness of Trisomy 18.


WolkConnect libraries are used to enable a device’s communication with WolkAbout IoT Platform. Using WolkConnect libraries in the software or firmware of a device will drastically decrease the time to market for developers or anyone wanting to integrate their own product with WolkAbout IoT Platform.
WolkConnect libraries are intended to be used on IP enabled devices. The available WolkConnect libraries (implemented in the following programming languages C, C++, Java, Python) are platform independent for OS based devices, with a special note that the WolkConnect-C library is suitable to be adapted for the use on non-OS devices as WolkConnect libraries have a small memory footprint.
Features of WolkAbout IoT Platform that have been incorporated into WolkConnect libraries will be disambiguated with information on how to perform these features on devices by using WolkConnect’s API.
WolkConnect libraries are open-source and released under the Apache Licence 2.0.
WolkConnect library is intended to be used as a dependency in other firmwares or softwares that have their own existing business logic. WolkConnect library is not, by any means, a single service to control the device, it is a library intended to handle all the specific communication with WolkAbout IoT Platform.
Using WolkConnect library requires minimal knowledge of WolkAbout IoT Platform, no knowledge of the internal mechanisms and protocols of WolkAbout IoT Platform is necessary. The user only utilises APIs provided by WolkConnect library in the User Application Layer, thereby reducing time-to-market required.
The architecture of software/firmware where WolkConnect library is meant to be used is presented in Fig.1.1. The gray section in Fig.1.1 represents the developer's software/firmware.
The gray section between the User Application Layer and the Hardware Abstraction Layer reDevice DataDevice Datapresents the user’s libraries and drivers that are required for his project. Providing WolkConnect library with IP connectivity from the Hardware Abstraction Layer is expected from the user.
WolkConnect library is separated into layers as shown in Fig.1.2
WolkConnect libraries use IP connectivity provided by the OS, but on devices, where this not available, it is user’s responsibility to provide implementations for opening a socket and send/receive methods to the socket.
Communication between WolkConnect library and WolkAbout IoT Platform is achieved through the use of the MQTT messaging protocol. WolkConnect libraries have a common dependency, an implementation of an MQTT client that will exchange data with an MQTT server that is part of WolkAbout IoT Platform. The communication between WolkConnect library and WolkAbout IoT Platform is made secure with the use of Secure Sockets Layer (SSL).
Another common dependency for WolkConnect libraries is JSON library that is used for parsing data that is exchanged with WolkAbout IoT Platform. This data is formatted using a custom JSON based protocol defined by WolkAbout IoT Platform.
The high-level API represents what is available to the developer that is using WolkConnect library. APIs follow the naming convention of the programming language they were written in. Consult a specific WolkConnect library’s documentation for more information. The API is divided into two parts: data management and device management. Data handling is independent of device management on WolkAbout IoT Platform and therefore has a separe API. Device management is responsible for device health and this, in turn, increases the device’s lifespan.
WolkConnect libraries separate device’s functionality through the API into three distinct parts:
Every connection from WolkConnect library to WolkAbout IoT Platform is authenticated with a device key and a device password. These credentials are created on WolkAbout IoT Platform when a device is created and are unique to that device. Only one active connection is allowed per device. Attempting to create an additional connection with the same device credentials will terminate the previous connection. The connection is made secure, by default, in all WolkConnect libraries through the use of Secure Sockets Layer (SSL). Connecting without SSL is possible. For more information, refer to specific WolkConnect library documentation.
Connect
A device can be connected to WolkAbout IoT Platform in two ways: Always connected devices - connect once and publish data when necessary. Actuations can only be used in this case, as sending actuations from WolkAbout IoT Platform are disabled when the device is offline. Periodically connected devices - connect and publish data when needed. It is important to use disconnect here, as this is a valid device state on WolkAbout IoT Platform - controlled offline.
Disconnect
Disconnecting will gracefully terminate the connection and the device will momentarily appear offline on WolkAbout IoT Platform. In cases of ungraceful disconnections, eg. due to a networking error, WolkAbout IoT Platform will be able to determine if the device is offline based on whether the device has send a message from its keep-alive mechanism. After waiting for the keep-alive mechanism timeout with no message, WolkAbout IoT Platform will declare the device offline.
Keep-Alive Mechanism
In cases where the device is connected to the Platform but is not publishing any data for the period of 30 minutes, the device may be declared offline. This is especially true for devices that only have actuators, for example. To prevent this issue, a keep-alive mechanism will periodically send a message to WolkAbout IoT Platform. This mechanism can also be disabled to reduce bandwidth usage.
Real world devices can perform a wide variety of operations that result in meaningful data. These operations could be to conduct a measurement, monitor certain condition or execute some form of command. The data resulting from these operations have been modeled into three distinct types of data on WolkAbout IoT Platform: sensors, alarms, and actuators.
Information needs to be distinguishable, so every piece of data sent from the device needs to have an identifier. This identifier is called a reference, and all the references of a device on WolkAbout IoT Platform must be unique.
Sensors
Sensor readings are stored on the device before explicitly being published to WolkAbout IoT Platform. If the exact time when the reading occured is meaningful information, it can be assigned to the reading as a UTC timestamp. If this timestamp is not provided, WolkAbout IoT Platform will assign the reading a timestamp when it has been received, treating the reading like it occured the moment it arrived.
Readings could be of a very high precision, and although this might not be fully displayed on the dashboard, the information is not lost and can be viewed on different parts of WolkAbout IoT Platform.
Sensors readings like GPS and accelerometers hold more than one single information and these types of readings are supported in WolkConnect libraries and on WolkAbout IoT Platform. This concept is called a multi-value reading.
Alarms
Alarms are derived from some data on the device and are used to indicate the state of a condition, eg. high-temperature alarm which emerged as a result of exceeding a threshold value on the device. Alarm value can either be on or off.
Like sensor readings, alarm messages are stored on the device before being published to WolkAbout IoT Platform. Alarms can also have a UTC timestamp to denote when the alarm occurred, but if the timestamp is omitted then WolkAbout IoT Platform will assign a timestamp when it receives the alarm message.
Actuators
Actuators are used to enable WolkAbout IoT Platform to set the state of some part of the device, eg. flip a switch or change the gear of a motor.
Single actuation consists of the command to a device and feedback from the device. A command is a message that arrived at the device. Feedback is the current status of the actuator on the device which needs to be sent to WolkAbout IoT Platform in order to complete a single actuation process. Current status has two parameters: actuator value and actuator state. Value is current value of the actuator, eg. for a switch, it can be true or false. Possible actuator states are:
To perform a successful actuation, user needs to know the actuator references he was required to enter in the manifest, on the Platform, to forward them during the actuation initialisation period. The user has to implement an actuation handler that will execute the commands that have been issued from WolkAbout IoT Platform. Then the user has to implement an actuation provider that will update WolkAbout IoT Platform with the current status of the actuator. Publishing actuator statuses is performed immediately, but if the actuator takes time to be executed, eg. closing the gate, then the actuator status will update WolkAbout IoT Platform with the current values until it reaches the commanded value. If the device is unable to publish the actuator status, then the information will be stored on the device until the next successful publish attempt.
To summarise, when an actuation command is issued from WolkAbout IoT Platform, it will be passed to the actuation handler that will attempt to execute the command, and then the actuator status provider will report back to WolkAbout IoT Platform with the current value and state of the actuator.
Configuration
Configuration is the dynamical modification of the device properties from WolkAbout IoT Platform with the goal to change device behavior, eg. measurement heartbeat, sensors delivery reduction, enabling/disabling device interfaces, increase/decrease device logging level.
Configuration requires the same way of handling messages as actuation. When a configuration command is issued from WolkAbout IoT Platform, it will be passed to the configuration handler that will attempt to execute the command. Then the configuration status provider will report back to WolkAbout IoT Platform with the current values of the configuration parameters, with the addition that configuration parameters are always sent as a whole, even when only one value changes.
Device Software/Firmware Update
WolkAbout IoT Platform gives the possibility of updating the device software/firmware. The process is separated into three autonomous stages:
The device needs to be connected to and deliver current software/firmware version to WolkAbout IoT Platform before starting to exploit software/firmware update.
WolkAbout IoT Platform actuates the device to start the process of installing. The responsibility to successfully install the file is on a device, not on WolkConnect library. In order to update the firmware, the user must create a firmware handler.
This firmware handler will specify the following parameters:

Introduction
To give a brief introduction to the idea of the digital divide, I think a quote from Eric Roberts, professor at Standford University, can be useful in providing a great foundation.
“The ability to access computers and the internet has become increasingly important to completely immerse oneself in the economic, political, and social aspects of not just America, but of the world. However, not everyone has access to this technology. The idea of the "digital divide" refers to the growing gap between the underprivileged members of society, especially the poor, rural, elderly, and handicapped portion of the population who do not have access to computers or the internet; and the wealthy, middle-class, and young Americans living in urban and suburban areas who have access.” --Prof. Eric Roberts, Stanford University
Our Goal
In the subsequent sections, we hope to further flesh out and detail the idea of the digital divide and how it affects different parts of the world in numerous ways, adapting our white paper research for more digital-friendly consumption.


Introduction
Containerization, also known as operating-system-level virtualization is a feature of the operating system in which the kernel allows the existence of multiple isolated user-space instances. Such instances may be called containers, partitions, virtualization engines (VEs), or jails. These look like real computers from the point of view of a program running in them.

Images
- Docker image is an executable package that includes everything needed to run an application - code, libraries, environment variables, and configuration files.
- An image is a read-only template with instructions or creating a docker container. It is possible for an image to be based on another base image, with additional customizations.
- Images are created using
Dockerfile
with a simple syntax the defines the steps involved in creating the image and run it. Each instruction in theDockerfile
creates a layer in the image and cached for the next build to speed up the process until theDockerfile
is changed itself.
# list images
docker image ls
docker images
# list all images on machine
docker image ls -a
# remove image from machine
docker image rm <image id>
# remove all images from this machine
docker image rm $(docker image ls -a -q)
Container
- Docker container is launched by running an image. Container is to image, what object is to class, i.e. container is a runtime instance of an image, or what the image becomes in memory when executed.
- A container is defined by the image used to spawn it and the configuration options provided while creating or running it.
- When a container is removed, any changes in the state not stored in the persistent storage disappear.
# list all running containers
docker container ls
docker ps
# list all containers
docker container ls --all
docker container ls -a
# list all containers in quite mode
docker container ls -aq
# docker container stop using container id
docker container stop <container-id>
# docker container kill using container id
docker container kill <container-id>
# docker container remove using container id
docker container rm <container-id>
# remove all containers
docker container rm $(docker container ls -a -q)
docker container ls -a | awk '{print "docker container rm ",$1}' | bash
# attach to a running container
docker attach <container-id>
Ctrl-c
to kill the container.Ctrl-p Ctrl-q
sequence to detach from an running container without killing it.
Container vs Virtual Machines
A container runs natively on Linux, sharing the kernel of the host machines with other containers. It only runs processes and occupies memory required by that executable, hence making it lightweight.
On the contrary, a virtual machine runs a full guest operating system with virtual access to the host resources through a hypervisor. As a result, VMs provide an entire guest operating system and hence a lot more resources than what the application would actually need.
Dockerfile
- Dockerfile defines the envrionment inside the container. Options like access to resources, disk drives etc. can be configured in the file. Post this, it can expected that the builds from this Dockerfile would behave the same wherever it runs.
# tensorflow nightly build base image with python 3
FROM tensorflow/tensorflow:nightly-py3
# set working directory
WORKDIR /development
# Copy the current directory contents into the destination directory
ADD . /development
# setup command line tools
RUN apt-get update && apt-get install -y \
emacs \
git \
tmux \
&& \
apt-get clean && \
apt-get autoremove && \
rm -rf /var/lib/apt/list/*
# setup non-pip libraries
RUN ["apt-get", "install", "-y", "python-opencv"]
# install requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt
# expose ports for connection
# 6006 for tensorboard
# 8888 for jupyter notebook
EXPOSE 6006 8888
CMD ["/bin/bash"]
Build from Dockerfile
- Once the Dockerfile is ready, it can be used to build and run the image by using the following commands,
# build image from Dockerfile
docker build -t <docker-image-name> .
# run container in interactive mode
docker run -it <image-name> <optional-command-to-overwrite-base-command>
# run container in detached mode
docker run -d <image-name>
# run container with port forwarding
docker run -p <host-port>:<container-port-exposed> <image-name>
Docker Hub
- Dockerhub is the public repository of docker images where anyone can publish their images or pull images from. Image names on dockerhub have a name based on username of uploader, project name and tags based on properties of docker image - latest, nightly etc. A template would look like: username/repository:tag
- Once uploaded, all the images are publically available and can be availed on any system with connectivity, because if an image in not available locally, docker tries to pull it from the repository.
# login to dockerhub
docker login
# tag <image> for upload to registry
docker tag <image> username/repository:tag
# upload tagged image to registry
docker push username/repository:tag
# run image from a registry
docker run username/repository:tag
# pull tagged image from registry
docker pull username/repository:tag
Services
- Services are just containers in production. A service runs only one image, but along with it other information is also maintained - ports it should run on, number of replicas of the container to be maintained etc.
- Scaling a service basically means to change the number of containers running the particular piece of the software, assigning more compute resources to service in the process.
- Services allow the containers to be scaled across multiple docker daemons, which all work together in a swarm using multiple managers and workers. Each member of the swarm in a docker daemon communicating with other daemons using Docker APIs.
Swarms
- A swarm is a group of machines that are running docker and joined into a cluster. Post definition of the cluster, all the commands are run on the entire cluster by a swarm manager. The machines in a cluster can be virtual or physical, and are termed as nodes.
Swarm managers can be configured in the compose file to use several different strategies to deploy new containers on the cluster,
- Emptiest Node: runs the container on the least utilized machine.
- Global: each machine gets exactly one instance of the specified node.
Swarm managers are the only machines that can run commands on a swarm or allow new nodes to join as a worker in the cluster. Workers are only capable of donating the compute power but do not have the authority to rule any other machine using commands.
The moment swarm mode is switched on, the current machine becomes the swarm mananger and any commands run henceforth are run on the cluster by the swarm manager.
Setting up swarm,
- run
docker swarm init
to enable the swarm mode and make the current machine the swarm manager - run
docker swarm join
on other machines to make them join the cluster - run
docker swarm leave
on worker to leave the swarm
Always run
docker swarm init
anddocker swarm join
with port 2377 (the swarm management port), or let it take the default port by leaving it empty.
The machine IP addresses returned by
docker-machine ls
include port 2376, which is the Docker daemon port. Do not use this port or you may experience errors.
Docker Machine
- Docker machine helps to start and manage the virtual machines in a cluster with ease.
# create a virtual machine
docker-machine create --driver virtualbox <vm-name>
# list as docker machines
docker-machine ls
# send command to docker machines
docker-machine ssh <vm-name> <command>
# to use the native ssh of docker
docker-machine --native-ssh ssh <vm-name> <command>
# configure shell to interact with docker machine
eval $(docker-machine env <vm-name>)
Development Notes
There are various advantages of using docker for machine-learning development,
- Library dependencies for complex machine learning libraries like tensorflow can be cumbersome to build sometimes. Using base images it is easier to load them.
- Open-source docker images like this that give most of the libaries one may use, out of the box.
- It can help run mutliple CUDA/cuDNN versions on the same machines based on project requirements.
- Services and Swarms can help run experiments on bigger swarms using more compute power from mutliple workers that might not be easily available on a single machine.
- Once a system with basic dependencies is ready there would not be any overhead of reiterating the setup process on any other machine thanks to the excellent portability that docker offers, regardless of the host operating systems.
Note: Updated copy of Docker Setup Files
Stack
- A stack is the top-most hierarchy of the docker containerization. It is the group of related services that share dependencies, and can be orchestrated and scaled together. A single stack is capable of defining and coordinating the functionality of the entire application.
Docker Architecture
- Docker uses a client-server architecture.
- The docker client speaks to docker daemon, which does the building, running and managing of the docker containers.
-
The client and daemon communicate through REST APIs.
- Docker Daemon: listens to the APIs and manages the images, containers, networks and volumes. A daemon can communicate with other daemons and clients to manager the docker system.
- Docker Client: the primary way of communicating with the docker daemons. All the commands executed at the client are internally routed to
dockerd
which then executes them. A single docker client can communicate with many different docker daemons. - Docker Registries: stores the docker images. For example, docker hub and docker cloud are the public repositories that anyone can use, and docker is configured by default to look for a image in docker hub in case it does not find local copy. It is also possible to run private registries. Commands like
docker pull
anddocker run
fetch the required images from the configured repositories.
Miscellaneous
- Docker is written in go language.
- It is built to utilize the features of linux kernels in its full advantage.
- Docker provides container isolations using namespaces. On executing
docker run
, docker creates a set of namespaces for the container. Each aspect of the container is run on a different namespace and its access is limited to that namespace.
Namespaces

COMM LAB 30MFF.
Inspiration For the Film
What lead us to make the film. well we did not know that we had to make a film, we were having a normal class and the professor told us that we would be doing something creative. The creative thing was that we had to make the 30MFF in one hour. so i think that is the story in what got us to make the Film. on the concept of the film well we were to lazy to take the camera and try to record something cool. so we thought why not just record the zoom session and use it as the 30MFF. but we were to lazy to when get out of our seats so we came up with this concept of passing around things to make a insynch type of a video.
The film was made with the consent and permission of everyone involved. the idea and concept of the film was also universally decided and agreed upon by everyone involved. we also respect the privacy of everyone involved in the film. permission was taken to display any info related to them. I the person choose to not provide information we added placeholder images and text in order to unhold our privacy agreemnent. more information regarding the fair use of all assets can be addrressed to our support email<EMAIL_ADDRESS>any questions regrading the people involved in the film will be put through a permission process before more information regarding the topic is provided


Adding a policy will allow its specific functionality to be applied to the API invocation as part of the overall policy chain.
