In this tutorial I want to help you get started with actual code and a (could-be) real world use case.
Let’s pretend we have a company called Smarty Lighting and we do smart-city lighting systems.
We want to create a system capable of turning on/off the streetlights depending on the environmental conditions of each of them:
We’ll use Node.js to code our APIs and Mosquitto as our message broker. Please note this is just my choice for the tutorial but what is going to be explained here is applicable to any other programming language and message brokers.
Let’s start by creating an AsyncAPI file to describe our API. It will help us generate the code and the documentation later.
asyncapi: '2.0.0'
info:
title: Streetlights API
version: '1.0.0'
description: |
The Smartylighting Streetlights API allows you
to remotely manage the city lights.
license:
name: Apache 2.0
url: 'https://www.apache.org/licenses/LICENSE-2.0'
servers:
mosquitto:
url: mqtt://test.mosquitto.org
protocol: mqtt
channels:
light/measured:
publish:
summary: Inform about environmental lighting conditions for a particular streetlight.
operationId: onLightMeasured
message:
payload:
type: object
properties:
id:
type: integer
minimum: 0
description: Id of the streetlight.
lumens:
type: integer
minimum: 0
description: Light intensity measured in lumens.
sentAt:
type: string
format: date-time
description: Date and time when the message was sent.
Let’s break it down into pieces:
asyncapi: '2.0.0'
info:
title: Streetlights API
version: '1.0.0'
description: |
The Smartylighting Streetlights API allows you
to remotely manage the city lights.
license:
name: Apache 2.0
url: 'https://www.apache.org/licenses/LICENSE-2.0'
asyncapi
field indicates we want to use AsyncAPI version 2.0.0.info
field we can find information about the API, like its name, version, a description and its license.We’re now going for the channels section. It is used to describe the event names your API will be publishing and/or subscribing to.
channels:
light/measured:
publish:
summary: Inform about environmental lighting conditions for a particular streetlight.
operationId: onLightMeasured
In this example, light/measured
is the channel name your API will allow you to publish
to. The operationId
property, describes what will be the name of function or method that will take care of this functionality in the case we generate code (which is the case). To understand how the event should look like when publishing to that channel, there is the payload
property:
payload:
type: object
properties:
id:
type: integer
minimum: 0
description: Id of the streetlight.
lumens:
type: integer
minimum: 0
description: Light intensity measured in lumens.
sentAt:
type: string
format: date-time
description: Date and time when the message was sent.
It defines the content of the event using AsyncAPI schemas. It means that our event payload should contain an id
and a lumens
property —which are integers bigger than zero—, and a sentAt
property that should be a string containing a date and time.
JSON Schema Draft 07 is 100% compatible with AsyncAPI schemas.
Cool! So we’re done with our AsyncAPI file! Let’s get into generating code.
To generate our code we’ll use the AsyncAPI Generator Node.js template.
npm install -g asyncapi-generator
(You might need to use sudo)
Create a directory for your projects and step into it:
mkdir streetlights && cd "$_"
Create a file with the AsyncAPI machine-readable description we created before:
touch asyncapi.yaml
# Open asyncapi.yaml and paste the definition
And now let’s generate the code for it:
ag asyncapi.yaml nodejs -p server=mosquitto
And voilà!
Before running your code don’t forget to install the dependencies on every project:
npm install
Run the code:
npm start
Now that you have your code running you’ll want to test it, right? Go and install the mqtt library:
npm install mqtt -g
(You might need to use sudo)
Try to send messages to your service using the command line:
mqtt pub -t 'light/measured' -h 'test.mosquitto.org' -m '{"id": 1, "lumens": 3, "sentAt": "2017-06-07T12:34:32.000Z"}'
You should see our application logging the message you just sent.
We’ve learned how to create an AsyncAPI description file and how to generate code from it. The code is just a bootstrap and you’ll need to add your business logic into it. Take some time to play with it. There are still lots of things to be covered but I kept the tutorial simple on purpose, so you get an idea of the potential.
We would also like to see what you create with AsyncAPI. As an open-source project we’re open to proposals, questions, suggestions and contributions. If you don’t feel in the mood to contribute but you’re using AsyncAPI, just raise your hand creating a issue in our Github repo or join our Slack channel. Don’t be shy :)

Wrappers available in the PuppyIR Framework
The PuppyIR framework contains a number of varied search engine wrappers. In this section - an overview of these wrappers, in terms of their category, is provided in order to provide an easy access guide to what is available (to enable a developer to select what best suits the application they have in mind). This is intended as a supplement to the PuppyIR API Reference section which contains details of the implementation of these wrappers.
Please note that wrappers can, and do, appear in multiple categories as some wrappers are more general purpose than other, more specific, services. Also, the generic ‘web’ results category is not listed but is provided by, for example, ‘Bing’ please see the API guide for more.
Some of these wrappers require API keys (again, see the API reference for details) in these cases, this requires the developer to sign up for said key on the respective search service webpages for the API in question.
Book Services
- ‘GoogleBooks’ this wrapper provides access to the Google Books data store, you can search for books and, in some cases, retrieve samples or whole books for reading (you need to embed the samples if used in an application).
Image Services
These wrappers provide the ability to search for and retrieve image results.
- ‘Bing’ and ‘BingV2’
- ‘Flickr’
- ‘Picassa’
Location Based Searching
These services allow for searching for: either results in a defined location or for a location itself.
N.B. Google Geocode should be used to retrieve the geo-coordinates and/or bounding box to use with the other services as their location based parameter(s).
For an example of this in action, a prototype (it should be noted, that this prototype was abandoned and the code is quite rough in addition to it not being styled) is available which you can download via:
$ svn co https://puppyir.svn.sourceforge.net/svnroot/puppyir/branches/working/LSee LSee
$ cd LSee
$ python manage.py runserver
Visit: http://localhost:8000/lsee
- ‘Flickr’ allows for the retrieval of geotagged images within a defined bounding box.
- ‘Google Geocode’ this service allows results to be retrieved for locations, for example, if you search for ‘Edinburgh’ it will return details of the various Edinburgh’s around the world (like their location/latitude).
- ‘Twitter’ allows for the retrieval of geotagged tweets made within a box defined by a point - the origin - with a radius to define a box around the point.
- ‘YouTubeV2’ allows for the retrieval of geotagged videos from within a box defined by a point - the origin - with a radius to define a box around the point.
Movie Services
- ‘Rotten Tomatoes’ allows for the retrieval of details about movies like: the cast and aggregated review score etc.
Music Services
N.B. YouTube and YouTubeV2 are also, arguably, a music based services due to the large proportion of music based content.
- ‘ITunes’
- ‘LastFM’
- ‘Soundcloud’
- ‘Spotify’
News Services
These wrappers provide the ability to search for news stories
- ‘Bing’ and ‘BingV2’ allow for the searching of the ‘news’ results.
- ‘Guardian’ is a wrapper for the search api of the UK based newspaper: the Guardian. While UK based this service also provides a large variety of stories about events the world over.
Social Network and Social News Services
- ‘Digg’ a social news website for sharing items which are then rated by the community - this acting as a method of filtering the quality of results.
- ‘Twitter’ a social network for posting short messages.
Spelling Suggestions and Dictionary based results
- ‘BingV2’ using the ‘spell’ source type spelling corrections to a query.
- ‘Wordnik’ this service provides a spelling correction feature, in addition to providing definitions of words and examples of words in context (via selections of text from various web pages).
- ‘WebSpellChecker’ allows for searching for spelling corrections in a variety of languages - there is no extra information returned however just the spelling correction suggestion.
Video Services
These wrappers provide the ability to search for videos. It should be noted that Bing’s search engine strongly favours YouTube results so there is a lot of overlap if both it and YouTube are used in the same application.
- ‘BingV2’
- ‘YouTube’ and ‘YouTubeV2’ results from YouTube come with an embed URL so they can be played in-line (as seen in the MaSe and aMuSeV3 prototypes).

[gecode-users] Propagators scheduling
José Luis Pulido Burbano
josel2820 at gmail.com
Tue Mar 10 16:50:11 CET 2009
Hello, Ive been taking a look into Gecode's code, as far as I understand
a propagator is scheduled when any of its variables return a certain
modification Event
that is related to the PropCond.
When a variable is subscribed to an advisor and the advisor's propagator
overwrites the advise function
then the advise method is called in order to establish whether or not to run
the propagator's propagate method when the subscribed variable is modified.
So when the propagator is scheduled because of its PropCond then the advise
method wont be called.
am I right about it?
thanks in advance

Rhea Ripley has some choice words for Becky Lynch and Shayna Baszler
by Shubham RoyIn an exclusive backstage interview, WWE NXT Superstar Rhea Ripley had some words to spare for Becky Lynch and Shayna Baszler after her match with Becky was interrupted by NXT Women's Champion Shayna Baszler and Jessamyn Duke and Marina Shafir.
Rhea on making the most of her opportunities
Tonight's episode of WWE NXT kicked things off with the return of WWE RAW Women's Champion Becky Lynch to the NXT Arena for the first time in almost three years. The Man is slated to have a triple threat match between WWE NXT Women's Champion Shayna Baszler and WWE SmackDown Women's Champion Bayley at Survivor Series this coming Sunday to establish brand supremacy.
Becky came out to the ring and said that even though Triple H issued an open invitation for tonight, she was coming anyway. She had some strong words for Shayna Baszler and Bayley, while also going on to issue a challenge to Baszler and the Horsewomen to come down to the ring. Her challenge was however met by Rhea Ripley.
The match between Ripley and Lynch was going perfectly but was interrupted due to interference from Baszler and the Horsewomen. Ripley spoke to a backstage correspondent after her match and said that careers in NXT are built on opportunities and tonight she made the most of it.
Additionally, she also had some choice words for both Lynch and Baszler.
Around here, careers are built on opportunities. Tonight I took my opportunity to prove to the so-called Man[Becky Lynch] that around here in NXT, she's not The Man. As for Shayna Baszler and her Muppets[Jessamyn Duke and Marina Shafir]? NXT TakeOver: WarGames, I'm gonna take my opportunity.

Qt Remote Objects Registry
The registry provides a simpler way to establish these connections. Every node that wants to be part of the registry's network connects to the registry. The registry is itself a specialized source object, and thus is hosted by a node. Connecting to the registry is simply a matter of passing the registry's URL to the QRemoteObjectNode or QRemoteObjectHost constructor, or passing the URL to the setRegistryUrl method.
The registry is tightly integrated with QtRO. Whenever a Source is added or removed, the name/URL is updated in the registry automatically. So once your node is connected to the registry, it is not necessary to connect to any other nodes manually. If you request an object on the network and you aren't connected to the hosting node, the registry will know what URL to connect to and will initiate the connection. Once connected (and the list of available objects is passed along, including the desired Source), the initialization process for the requested Replica will start automatically.

We represent a diverse range of disciplinary backgrounds, including: epidemiology, virology, biostatistics, operations research, and health economics. Like so many other research teams around the world, we have dropped what we are doing, volunteered our time and effort, and convened to help predict and understand the trajectory of the COVID-19 pandemic.
WHAT WE DO
We are distinguished from other COVID-19 modeling groups by our focus on decisions and the role that information plays in those decisions. A large number of us have advanced training in decision science and so-called value-of-information methods. This leads us to prioritize pragmatic decision support and the careful management of uncertainty in our modeling. We view the model-building exercise as a practical means of ‘taking stock’ of the evidence base: assembling what we know, identifying what don’t we know, and evaluating what we might be willing to give up (in terms of time, new infections, costs, and/or mortality) to acquire better information.
Our model development activities have both short- and long-term objectives: In the short-term, we aim to predict the impact of imminent public health control measures on the trajectory of the epidemic and on the use of scarce healthcare resources. We are using our models to identify what we know, what we don’t know, and where/how our data collection and analysis efforts might most usefully be deployed to improve longer-term decision making.

While reading documents in Python, it’s common to see the terms like iterable
, iterator
, and generator
.
Unfortunately, however, I have not tried to understand these confusing concepts clearly so far, so let me try to make these concepts clear in this post. (But, in order to avoid putting too many contents in this post, I will cover generator
in the next post.)
“What is iterable?”
- It is an object that is able to return its members one at a time.
- Then, how we could make it available to return members of a certain object one at a time?
- Iterable objects should support at least either
__iter__()
or__getitem__()
method. list
,str
,tuple
,dict
, and objects of any classes you define with__iter__()
or__getitem__()
methods are all iterables.- Iterables can be used in a
for
loop. - When Iterables passed as an argument to the built-in function
iter()
, it returns an iterator object.
Let’s make a simple iterable
that has __getitem()__
function.
The output is as follows:
0
0
0
0
<class 'iterator'>
You can now see that this mock iterable can be used in for
loop, and turned into iterator
type when passed to built-in iter()
function. (NOTE: What for
loop does behind the scenes, in fact, is to call iter()
)
Then, “What is iterator?”
As we have seen so far, iterator
is generated through passing iterable
to iter()
function.
Then, what is the essence of iterator
? How we can iterate over different iterators?
There is a specific protocol for iterator, which is as follows:
- Iterator object has the method
__next__()
which accesses members in the given object one at a time. - And, when there are no more members,
__next__()
raisesStopIteration
exception which causes for loop to terminate.
Just like iterable
, iterator
can easily be implemented like the following:.
The output is as follows:
0
0
0
As a side note, many built-in functions accept iterators as arguments:
The code snippets above results in:

std.parallelism.task
- multiple declarations

- Function task
- Function task
- Struct Task
Function task
Creates a
on the GC heap that calls an alias. This may be executed
via Task
or by submitting to a
Task.executeInNewThread
std.parallelism.TaskPool
. A globally accessible instance of
is provided by TaskPool
std.parallelism.taskPool
.
Prototype
auto task(alias fun, Args...)( Args args );
Returns
A pointer to the
.
Task
Examples
// Read two files into memory at the same time. import std.file; void main() { // Create and execute a Task for reading // foo.txt. auto file1Task = task!read("foo.txt"); file1Task.executeInNewThread(); // Read bar.txt in parallel. auto file2Data = read("bar.txt"); // Get the results of reading foo.txt. auto file1Data = file1Task.yieldForce; }
// Sorts an array using a parallel quick sort algorithm. // The first partition is done serially. Both recursion // branches are then executed in parallel. // // Timings for sorting an array of 1,000,000 doubles on // an Athlon 64 X2 dual core machine: // // This implementation: 176 milliseconds. // Equivalent serial implementation: 280 milliseconds void parallelSort(T)(T[] data) { // Sort small subarrays serially. if(data.length < 100) { std.algorithm.sort(data); return; } // Partition the array. swap(data[$ / 2], data[$ - 1]); auto pivot = data[$ - 1]; bool lessThanPivot(T elem) { return elem < pivot; } auto greaterEqual = partition!lessThanPivot(data[0..$ - 1]); swap(data[$ - greaterEqual.length - 1], data[$ - 1]); auto less = data[0..$ - greaterEqual.length - 1]; greaterEqual = data[$ - greaterEqual.length..$]; // Execute both recursion branches in parallel. auto recurseTask = task!parallelSort(greaterEqual); taskPool.put(recurseTask); parallelSort(less); recurseTask.yieldForce; }
Function task
Creates a
on the GC heap that calls a function pointer, delegate, or
class/struct with overloaded opCall.
Task
Prototype
auto task(F, Args...)( F delegateOrFp, Args args ) if (is(typeof(delegateOrFp(args))) && !isSafeTask!F);
Examples
// Read two files in at the same time again, // but this time use a function pointer instead // of an alias to represent std.file.read. import std.file; void main() { // Create and execute a Task for reading // foo.txt. auto file1Task = task(&read, "foo.txt"); file1Task.executeInNewThread(); // Read bar.txt in parallel. auto file2Data = read("bar.txt"); // Get the results of reading foo.txt. auto file1Data = file1Task.yieldForce; }
Notes
This function takes a non-scope delegate, meaning it can be
used with closures. If you can't allocate a closure due to objects
on the stack that have scoped destruction, see
, which
takes a scope delegate.

Struct Task
represents the fundamental unit of work. A Task
may be
executed in Task
parallel
with any other
. Using this struct directly
allows future/promise parallelism. In this paradigm, a function (or delegate
or other callable) is executed in a thread other than the one it was called
from. The calling thread does not block while the function is being executed.
A call to Task
, workForce
, or yieldForce
is used to
ensure that the spinForce
has finished executing and to obtain the return
value, if any. These functions and Task
also act as full memory barriers,
meaning that any memory writes made in the thread that executed the done
are guaranteed to be visible in the calling thread after one of these functions
returns.
Task
The std.parallelism.task
and std.parallelism.scopedTask
functions can
be used to create an instance of this struct. See
for usage examples.
task
Function results are returned from
, yieldForce
and
spinForce
by ref. If workForce
fun
returns by ref, the reference will point
to the returned reference of fun
. Otherwise it will point to a
field in this struct.
Copying of this struct is disabled, since it would provide no useful semantics. If you want to pass this struct around, you should do so by reference or pointer.

We wanted to make it easier for a student to focus on key learning activities: reading lecture notes, exploring lecture links, or completing lecture exercises. Because not all students are linear thinkers or linear learners we wanted to give them the option to explore different types of lecture content with random access, using a table of contents.
We also felt that it would be beneficial if students could take all of their quizzes and exams online - without the need to wait for an email that would then have to be opened, and from which some items may have to be downloaded. - We built a demo test and solution page. The later should be lockable until everyone is ready.
Here we wanted a place for the course instructor to manage the course online: quizzes, labs, surveys, exams, all in one place as well as being able to generate reports and see statisticss on students performance for the current semesters, any past semester, on any aggregate thereof. We also want to save trees and make world a better place by putting an end to printing on paper.
A wise man once said 70% of the time for building a website goes into planning and the sitemap (and the tooltips there) shows the innovative vision we have for the COMP1950 site, such as the file section that makes reviewing materials much easier for the student.
The lecture pages contain hours of material and as such are very long, which makes them hard to navigate. Further there's many pages, which would make building a page navigation a nightmare (probably why there wasn't one before). A javascript solution automatically scans each page that includes an empty div with id="#toc-to-here"
and makes the text of the headings (made URL friendly) as their id to build a dynamic list of contents that can be revealed/hidden by a fixed button that stays available at all times.
Both the print and projector styles add to the main style. Through the media call the print sheet is activated when someone attempts to print the page while the projector stylesheet is available (in addition to the usual way in Firefox) through a style switcher widget in the footer.The style switcher could easily be expanded to hold more style sheets, and a script could adds CSS files from a folder automatically.
It's nice to see what you can accomplish just with CSS, but commenting that code well enough for others to learn from it is another thing entirely. We suggest to consider having students submit CSS files for changing the new COMP1950 site and the ones that use the most interesting techniques and are well commented could be added to the collection of styles available.
A full CMS would be too heavy handed for the mostly static content, but having as much of the repeated content isolated into includes gives a similar benefit of only having to change things in one place without the full complexity. - So that's what the header.inc and footer.inc are for. Include them in each file and drastically reduce the amount of repeated content across files.
Due to scheduling conflicts meeting with the client before phase one's deadline wasn't possible. As such many decisions are still outstanding.
The sitemap shows one idea of how the navigation could be structured. It would be nested using accordeon effects. If the sitemap is approved such a navigation would be built, the current one is merely a stand-in.
Similarly the design of the front page depends on outstanding decisions about content. The idea that was explored here is a landing page that acts as high-level navigation.
In it's current form it's merely a proof of concept, none of the actual functionality is built in yet, as the exact scope and price would have to be arranged first.

“Self-awareness … is a neutral mode that maintains self-reflectiveness even in the
midst of turbulent emotions.”
Search within yourself by Chade-Meng Tan, Chapter 4: All natural, Organic Self confidence
What is the relationship between mindfulness and self awareness?
They are same thing, to be mindful is to self aware.
Try at least one of the self awareness practices from the chapter (Body Scan, Journaling). What was your experience of it? How did you feel?
I do a body scan meditation twice a day. Through the app Calm you can do guided meditation with a body scan. i find this method is because I hold anger and tension in my hands, it's why I have to keep clicking my little finger on my left hand back into place. My self doubt sits in my shoulders and my anxiety is in my chest, while my emotions are in my stomach, hence why I'm fat. Its the most valuable thing I've learnt and I 100% back this method.
What did you take away from the "My Emotions are Not Me" section?
I’m actually alot more self aware than i thought. I took this journey a few years back and I am very aware of my of my emotional spread and I took steps to get it in line. I also loved the explanation of self confidence, I have a screenshot with a quote from an TV show called Agent Carter that is my mantra
”I know my worth and no one else’s opinion of me matters”
I’m not arogant about who I am or how I betray myself, I just know what I am worth and who I am and I don’t care what other people think of me, at the end of the day the only opinion that matters is me. I am a flawed person who took the hard road more times than they can count but came out better. Everyday I strive to be kinder and wiser to myself and others around me.


| Can my component use multiple constructors? |
Yes.
You can code multiple constructors for a component:
class MyComp { private ThreadPool theThreadPool; public MyComp(ThreadPool threadpool) { theThreadPool = threadpool; } public MyComp() { theThreadPool = new DefaultThreadPool(); } // other methods. }
| How does PicoContainer decide what constructor to use? |
PicoContainer will instantiate a given component using the "greediest" satisfiable constructor. By greedy, we mean the constructor that takes the most parameters. By satisfiable, we mean constructors where all arguments can be satisfied by other registered components.
If you register a component with no satisfiable constructors, or two or more ambiguous "largest" constructors, a RuntimeException will be thrown when you ask for the component instance.
We recommend for most components, you use only one constructor, although this is by no means a requirement.
| How does PicoContainer compare to EJB containers? |
Oh blimey, it is rather different. EJB has loads of things you must extend, implement, provide and throw. It is also not an IoC design. It is close in that components are managed by a container, but the cumbersome and static nature of the JNDI lookups ensure that it is not actually IoC. PicoContainer is not a superset of EJB though, as it provides no remoting capability (but NanoContainer will). At least the PicoContainer compatible components hosted in this project do not.
| How does PicoContainer decide what constructor to use? |
PicoContainer will instantiate a given component using the "greediest" satisfiable constructor. By greedy, we mean the constructor that takes the most parameters. By satisfiable, we mean constructors where all arguments can be satisfied by other registered components.
If you register a component with no satisfiable constructors, or two or more ambiguous "largest" constructors, a RuntimeException will be thrown when you ask for the component instance.
We recommend, for the sake of predictablility, that PicoContainer compatible components use only one constructor, although this is by no means a requirement.
| How to use primitive types in constructors? |
PicoContainer will look for the greediest constructor of your component. But if your component's constructor depends on primitive types you may set the values explicitly.
public interface ThreadPool { void setSize(int); } public class MyComp { private ThreadPool threadPool; public MyComp(ThreadPool pool, int size) { threadPool = pool; threadPool.setSize(size); } }
In this case you can set the parameters at registration time:
DefaultPicoContainer pico = new DefaultPicoContainer(); pico.addComponent(ThreadPool.class, DefaultThreadPool.class); pico.addComponent(MyComp.class, MyComp.class, new Parameters[] { new ComponentParameter(), new ConstantParameter(new Integer(5)); }) MyComp myComp = (MyComp)pico.getInstance(MyComp.class);
Use ConstantParameter to set constant values and the ComponentParameter to let Pico resolve the dependency.
| When should I use PicoContainer? |
We recommend using PicoContainer when your application consists of many different classes (components) that are related to each other. Instantiating and lacing/connecting a lot of objects can be difficult task.
| Why Another IoC Framework? |
After a long period of watching Inversion of Control frameworks, and for some of us avoiding them because of their cumbersome nature, we got together to write what we believe is the simplest possible IoC design. One, perhaps, that considers the so-designed component as more important that the container.
When we set out to do this in 2003, there was nothing equivalent to PicoContainer (xContainer originally). XWork, that underpinned WebWork2 was a general/embeddable Setter Dependency Injection framework, but not well known. The Spring Framework started in the same timescale, and we were talking to its authors before Martin Fowlers Dependency Injection article. Later we discovered that HiveMind (now at Apache) also was in the same space.
| Why Constructor Injection? |
Constructor Injection is hard to swallow for people who have been living with Interface Lookup or Setter Injection for long. We think it's like TDD. Once you get the grasp of it, you don't go back. Here are some benefits with this type of IoC:
| Will we support Guice's @Inject annotation transparently? |
We could compile PicoContainer against Guice.jar and leverage the @Inject method with a new InjectionFactory (and probably will). The problem is that there is no easy way to use an annotation without having its class in the classpath. There's no easy 'transparent' solution for this.
Things fail silently if the jar is missing, unless the annotation is used - then it fails noisily. Meaning, the mere declaration of an annotation on a component is not enough to cause a ClassNotFoundException on load, if its not used:
@Retention(RetentionPolicy.RUNTIME) @Target(value={ElementType.METHOD}) public static @interface Bar { }
import com.google.inject.Inject; public class Foo { @Inject @Bar public void setFoo(String str) { System.out.println("0>" + str); } public static void main(String[] args) throws NoSuchMethodException { Foo foo = new Foo(); foo.setFoo("hello"); Method m = Foo.class.getMethod("setFoo", String.class); Annotation[] anns = m.getDeclaredAnnotations(); System.out.println("1> " + anns.length); for (int i = 0; i < anns.length; i++) { Annotation ann = anns[i]; System.out.println("2> " + ann.toString()); } Annotation ann = m.getAnnotation(Inject.class); System.out.println("3> " + ann); } }
Leaving Guice out of the classpath, and trying to launch Foo...
commandline: java -cp classes Foo 0>hellos 1> 1 2> @Foo$Bar() Exception in thread "main" java.lang.NoClassDefFoundError: org/picocontainer/annotations/Inject at Foo.main(Foo.java:32)
The class loads, but the @Inject annotation is not present in the set of declared annotations, but another in the classpath is. Lastly when accessed explicitly, there is an exception thrown. Contrast to, the same run with Guice in the classpath:
0>hello 1> 2 2> @org.picocontainer.annotations.Inject() 2> @Foo$Bar() 3> @org.picocontainer.annotations.Inject()

1. Introduction to Computer Programming¶
1.1. Computer¶
1.1.1. What is a computer?¶
Is computer a calculator that is bigger and more advanced?
If computer is a calculator, then, is abacus the first computer invented?
Is your smartphone a computer?
What defines a computer?
In addition to performing arithmetic calculations, a computer is designed in such a way that
we can write different programs (in a process called programming or software development)
for the computer to execute to perform different tasks.
1.1.2. What is the architecture of a computer?¶
A computer contains three main hardware components:
Input device
Processing unit
Output device
<IP_ADDRESS>. Peripherals¶
Input and output devices connected to a computer are called peripherals.
They allow users to interact with the computer in different ways.
Exercise Some examples of output devices are:
Monitor
Speaker
Can you give an awesome example in the following box?
3D printer available at CityU
Exercise Some examples of input devices are:
Keyboard
Mouse
Can you give an awesome example?
3D scanner available at CityU
Exercise Many devices are both input and output device. Can you give at least 3 examples?
hard disk
CD/DVD Rom (writable)
touch screen
<IP_ADDRESS>. Central Processing Unit¶
The brain of a computer is its processor unit, or the Central Procesisng Unit (CPU).
It is located on the motherboard and connects to different peripherals using different connectors.
Two important components in the CPU are:
Arithmetic and Logic Unit (ALU): Performs arithmetics like a calculator (but for binary numbers)
Control Unit (CU): Directs the operations of the processor in executing a program.
Let’s run a CPU Simulator below from a GitHub project.
Note that all values are zeros in the RAM (Random Acess Memory) initially.
Under Settings, click
Examples->Add two numbers
. Observe that the values in the RAM have changed.Click

1.2. Programming¶
1.2.1. What is programming?¶
Programming is the process of writing programs.
But what is a program?
Exercise You have just seen a program written in machine language. Where is it?
The first six lines of binary sequences in the RAM. The last line Ends
the program.
The CPU is capable of carrying out
a set of instructions such as addition, negation, Copy, etc.
some numbers stored in the RAM.
Both the instructions and the numbers are represented as binary sequences.
E.g., in Intel-based CPU, the command for addition is like 00000011 00000100
1.2.2. Why computer uses binary representation?¶
%%html

Exercise The first electronic computer, called Electronic Numerical Integrator and Computer (ENIAC), was programmed using binary circuitries, namely switches that can be either On
or Off
.
However, it did not represent values efficiently in binary. 10 binary digits (bits) was used to represent a decimal number 0 to 9.
Indeed, how many decimals can be represented by 10 bits?
2 ** 10 # because there are that many binary sequences of length 10.
1024
As mentioned in the video, there are International Standards for representing characters:
ASCII (American Standard Code for Information Interchange) maps English letters and some other symbols to 8-bits (8 binary digits, also called a byte). E.g.,
A
is01000001
.Unicode can also represent characters in different languages such as Chinese, Japanese…etc.
There are additional standards to represent numbers other than non-negative integers:
2’s complement format for negative integers (e.g. -123)
IEEE floating point format for floating point numbers such as \(1.23 x 10^{-4}\).
Why define different standards?
Different standards have different benefits. ASCII requires less storage for a character, but it represents less characters.
Although digits are also represented in ASCII, the 2’s complement format is designed for arithmetic operations.
1.3. Different generations of programming languages¶
Machine language is known as the 1st Generation Programming Language.
Are we going to start with machine language? Start with learning 2’s complement and the binary codes for different instructions?
No. Programmers do not write machine codes directly because it is too hard to think in binary representations.
Instead, programmers write human-readable mnemonics such as ADD, SUB…,
called Assembly language, or the 2nd Generation Programming Language.
Are you going to learn an assembly language?
Both machine language and assembly language are low-level language which
are difficult to write for complicated tasks (requiring many lines of code), and
are platform specific:
the sets of instructions and their binary codes can be different for different types of CPUs, and
different operating systems use different assembly languages/styles.
Anyone want to learn assembly languages, and write a program in many versions to support different platforms?
Probably for programmers who need to write fast or energy-efficient code such as
a driver that controls a 3D graphics card, and
a program that control a microprocessor with limited power supply.
But even in the above cases, there are often better alternatives. Play with the following microprocessor simulator:
Click
CHOOSE A DEMO->LED
.Click
RUN SCRIPT
and observes the LED of the board.Run the demos
ASSEMBLY
andMATH
respectively and compare their capabilities.
%%html

1.4. High-level Language¶
%%html

Programmer nowadays use human-readable language known as the 3rd generation language (3GL) or high-level language.
Examples includes: C, C++, Java, JavaScript, Basic, Python, PHP, …
1.4.1. What is a high-level language?¶
A code written in high-level language gets converted automatically to a low-level machine code for the desired platform.
Hence, it abstracts away details that can be handled by the computer (low-level code) itself.
For instance, a programmer needs not care where a value should be physically stored if the computer can find a free location automatically to store the value.
Different high-level languages can have different implementations of the conversion processes:
Compilation means converting a program well before executing of the program. E.g., C++ and Java programs are compiled.
Interpretation means converting a program on-the-fly during the execution of a program. E.g., JavaScript and Python programs are often interpreted.
Roughly speaking, compiled programs run faster but interpreted programs are more flexible and can be modified at run time.
(The truth is indeed more complicated than required for this course.)
1.4.2. What programming language will you learn?¶
You will learn to program using Python. The course covers:
Basic topics including values, variables, conditional, iterations, functions, composite data types.
Advanced topics that touch on functional and object-oriented programming.
Engineering topics such as numerical methods, optimizations, and machine learning.
See the course homepage for details.
Why Python?
%%html

In summary:
Python is expressive and can get things done with fewer lines of code as compared to other languages.
Python is one of the most commonly used languages. It has an extensive set of libraries for Mathematics, graphics, AI, Machine Learning, etc.
Python is Free and Open Source, so you get to see everything and use it without restrictions.
Python is portable. The same code runs in different platforms without modifications.
How does a Python program look like?
# for step-by-step execution using mytutor
%reload_ext mytutor
%%mytutor -h 400
# The program here reads the cohort and reports which year the user is in
# Assumption: Input is integer no greater than 2020
import datetime # load a library to tell the current year
cohort = input("In which year did you join CityU? ")
year = datetime.datetime.now().year - int(cohort) + 1
print("So you are a year", year, "student.")
A Python program contains statements just like sentences in natural languages.
E.g., cohort = input("In which year did you join CityU? ")
is a statement that gives some value a name called cohort
.
For the purpose of computations, a statement often contains expressions that evaluate to certain values.
E.g., input("In which year did you join CityU? ")
is an expression with the value equal to what you input to the prompt.
That value is then given the name cohort
.
Expressions can be composed of:
Functions such as
input
,now
, andint
, etc., which are like math functions the return some values based on its arguments, if any.Literals such as the string
"In which year did you join CityU? "
and the integer1
. They are values you type out literally.Variables such as
cohort
andyear
, which are meaningful names to values.
To help others understand the code, there are also comments that start with #
.
These are descriptions meant for human to read but not to be executed by the computer.
Exercise What do you think the next generation programmimng should be?
Perhaps programming using natural languages. Write programs that people enjoy reading, like literate programming.
Indeed, Jupyter notebook is arguably a step towards this direction. See nbdev.

Dogma Directed by: Kevin Smith Starring: Matt Damon, Ben Affleck, Linda Fiorentino, Jason Mewes, Janeane Garofalo, Alan Rickman, Chris Rock, Salma Hayek, Kevin Smith, George Carlin Running time: 125 minutes My rating (5 star scale): ***
Loki (Damon) and Bartleby (Affleck) are angels who have been expelled from heaven and sent to Wisconsin. All they want to do is go home. They find a loophole in the divine punishment. Cardinal Glick (Carlin) is offering absolution to the first people to walk through the rededicated St. Michael's church in New Jersey. Loki and Bartleby forsake the cheese state for the garden state and a chance to reenter heaven.
Only if God is proven wrong, then the very fabric of creation is destroyed. So, to prevent them, Bethany (Fiorentino as a Catholic abortion clinic worker suffering a crisis of faith) is given the mission of stopping them by Metatron (Rickman as the angelic voice of God). Helping her are the prophets Jay (Mewes) and Silent Bob (Smith) who functioned as Greek chorus in Smith's first film Clerks. Along the way, she encounters the 13th apostle Rufus (Rock) and Serendipity a muse now working as a stripper (Hayek).
This film has been the victim of a boycott campaign launched by people who feel it mocks the Catholic faith. I'm not a Catholic, but I know a fair bit about Catholic theology. I also saw this film with a fairly devout Catholic. Neither of us saw anything objectionable in this movie. Some characters say and do things which the Church might disapprove of. But the characters who are presented as angelic or saints always stay within established Catholic doctrine. In fact, this is one of the few movies I have seen which correctly identifies angels as a separate order of creation (as opposed to the It's a Wonderful Life belief that dead people become angels). It comes down firmly on the side of the virgin birth, the miracle of the incarnation, the absolute power of God, and the authority of the Church. In fact, I can't think of a movie made this half of the century which so strongly affirmed the power and authority of the Church.
Having said all that, I understand why people feel the need to complain about this film. It suggests one can be a good Catholic and yet disagree with Church policy (Bethany is prochoice but is found to be righteous by Loki). The prophets (who are genuinely good at heart and clearly instruments of God) are drug dealers. But the key issue is that God is depicted as having a sense of humour. And religion, as we all know, is a very serious business.
I think those people are wrong. I like the idea that one can be a good person but sometimes do bad things. That suggests we all have some chance at being good. I like the argument that God is about redemption, salvation, and hope (all happy things) but all we focus on is sin, damnation, and punishment. And if Smith's God acts in incomprehensible and bizarre ways, well what do you expect of a divine being so awesomely powerful that humans cannot even hear Him talk without being killed by the force of His voice.
I think Smith takes religion pretty seriously and incorporates it into his everyday life. And I think he took that view with this movie, trying to bring out the spiritual aspects of mundane activities and mundane people. I think he has some interesting things to say about religion and he's gathered some interesting actors to say it. Rickman is great as the voice of God. Damon and Affleck have a great time as the two desperately unhappy angels yearning to return home. Rock is superb as the apostle with a mission, playing his part perfectly. And Smith may be the world's only genuinely funny mime as the brilliant and insightful Silent Bob. The rest of the cast never sink below good, although they rarely achieve excellence.
The problem in this movie lies not in the cast nor the idea, but in the general lack of jokes. I did laugh. I enjoyed the Catholicism Wow movement and the not so subtle attack on the Disney corporation. Everybody in the theatre laughed at times. But there was no hysterical laughter, no uproarious moments. There were moments with decent laughs and no more. As comedy, this film is average at best. As a movie to make you think, it score a little above average. It's worth catching at matinee prices but I don't think I could recommend full price for it.

Chipinge chief sells donated rice
Controversial Chipinge traditional leader, Chief Mpungu, is in the eye of storm again after he allegedly sold five tonnes of rice meant for his subjects.
by Luthando MapepaChief Mpungu (born Happson Nxumalo) made the headlines last month with another still pending issue with the Government after he sold a Government Isuzu double cab for a song. The rice was distributed to all chiefs and was meant for those affected by drought.
Irate villagers who spoke to The Manica Post said the chief was selling bags of rice to some civil servants in the area.

They argued that some neighbouring villagers received rice long back but villagers under Chief Mpungu did not get anything.
“Chief Mpungu together with other neighbouring chiefs received five tonnes from President Mnangagwa, meant for the less privileged villagers.
“The chief was responsible for disbursing the rice but what is surprising us is that the chief did not convene a meeting on how he would distribute it.
“We only heard that the chief was selling the rice for R300 and only civil servants in the village could afford it,” said a villager who declined to be named.
Another villager who also spoke on condition of anonymity said they only heard that the chief was allocated rice which was going to be distributed to those people who were affected by drought.
“There were some bags of rice which were being sold at Garahwa Business Centre for R300 and upon investigations it was pointed out that it was Chief Mpungu’s rice which was being sold at the business centre.”
Efforts to get a comment from Chief Mpungu proved futile since his mobile phones could not be reached by the time of going to print.
Contacted for comment, assistant district administrator for Chipinge Mr Tedious Beto confirmed receiving reports on the case.
“The issue is under investigation. We received complaints from the people there and our superiors have called us to investigate. We will furnish you with more details once the investigations are done,” he said. ManicaPost

RATING: 9/10 - BEST PICTURE - #10
Many things have been said about Kevin Smith's latest film and not everything was good. This movie has created more controversy than 'Fight Club'. It has been cursed by the Vatican and dozens of hate letters were sent to its creator. It truly is provocative, constantly on the edge, but also wonderfully refreshing. This is one of the kind -- a magnificent black comedy which is savagely funny and imaginatively philosophic. It is witty, accurate, fast paced and possibly one of the best satires in the history of the genre.
Starting with an apology that goes on for almost ten minutes, explaining to the audience that all characters and events are fictions and are not ment to be taken seriously, the story slowly takes shape. Loki (Matt Damon) is an angel that got drunk and flicked off the Lord (among others Alanis Morissette). Bartleby (Ben Affleck) is the co-conspirator who indirectly got both himself, and Loki, permanently kicked out of Heaven for Loki's infraction. Cardinal Glick (George Carlin) is the Catholic determined to reinvigorate the Catholic church by eliminating sacred objects such as Christ on the Crucifix, and replacing them with things such as Christ winking, smiling and giving the "thumbs up" to fervent church-goers. In an attempt to get people to give the "new and improved" Roman Catholic Church a try, the Cardinal declares that anyone passing through the Church's doors will be forgiven of all of their sins. This creates a loophole in church dogma that will allow them to end their eternal exile in Wisconsin and reenter the pearly gates of Heaven, sin-free. The problem is, if this happens, God will be proven fallible, and all of existence will be erased. With God having been put out of commission while on a holiday, the fate of the world and all else rests with efforts of a ragtag bunch: Metatron (Alan Rickman ), the angel who serves as the voice of God; Rufus (Chris Rock), the bitter, heretofore unknown 13th Apostle; a heavenly Muse Serendipity (Salma Hayek); a pair of familiar Prophets by the name Jay and Silent Bob (Jason Mewes and Smith himself); and the reluctant key figure in thwarting the renegade duo, Bethany (Linda Fiorentino), who has lost her faith in God, when a heralding angel appears in her bedroom and declares her the last descendant of Jesus and the potential savior of humanity. Of course there are plenty of bad guys and nasty obstacles to get in the way of our heroes and their attempt to save the past, present and future.
"Dogma" is never becomes boring or predictable. It is savagely funny with its many humorous lines, such as the dialoge between the messanger of God and Bethany:
Metatron: Moses was a drunk. Look what he accomplished. And no one's even asking you to part an ocean. All you have to do is go to New Jersey
Bethany: What's He like? God?
Metatron: Lonely. But funny. He's got a great sense of humor.
Or when the Muse is talking about her writing block:
Serendipity: Can you believe it? Me -- a muse, for God's sake! I sit down in front of the typewriter, and what do I get? Nothing. Blank page. I can't even write a grocery list.
Bethany: What about what you did with Jay and Silent Bob? You inspired them.
Serendipity: That's the cosmic joke. I can give out a zillion and nine ideas a second, but I can't keep any for myself. Her [God's] quirky sense of humor..
Between the humor and witty comparisons, lies a lot of intelligent and thought provoking material. Smith is elegantly shifting from amusing comedy, to intelligent drama, from sharp parody to creepy thriller. He plays with religion, twisting and stretching it, posing it in another light.  There is no pompous dialogue and Charlton Heston is not descending a mountain with a set of tablets in hand, however "Dogma" manages to exhibit a deep knowledge of not only the bible, and also the tenets of Christianity throughout the ages. And although that's what Vatican is stating, the audience will not be discouraged by this film, loosing their beliefs. There is a lot of symbolism in this movie, that is helping us realize that there is a supreme power that watches over us. The purpose of this film is not to provoke hatred and misbelief, but instead to gain faith and maybe look at the question of religion from a broader perspective.
When it comes to the visual aspect of this film, it is flawless. A solid cinematography and fast paced editing are framing the actors' impressive preformances. The two friends, Damon and Affleck, repeat the success of "Good Will Hunting" and are both a joy to watch. Alan Rickman and Chris Rock are fabulous, and Linda Fiorentino convincing. So, basically this should be a hit at the box office. But it's not just its provocative style and risky premise that stops "Dogma" from a being a serious Oscar-contender. There are some silly moments, when Smith goes a bit too far and the originality transforms into stupidity. But, forgetting these minor flops (luckily there are not many of them), this is a revalation. Some serious questions are raised about Catholic dogma and organized religion in general. By virtue of their definition and the fact that they're in regards to religion, these questions would understandably upset religious groups. But what those objectors fail to see that the questions raised, such as the dangerous differences between "beliefs" and "ideas," are intelligent ones that would only spring from the mind of someone who takes his or her faith seriously. It is a hilarious, intriguing, intelligent, bizarre and daring experience that is a spectacular analysis of human behavior, our needs, beliefs and problems since the beginning of time. The angry reactions that have met Smith, prove that he has managed to create an epic and should be taken as a compliment. And remember my words: "Dogma" will gain the status of a cult film in five years tops.

“All the times he played, he played very well”- Liverpool star hailed by national team coach
by Neelabhra RoyBrazil national team manager Tite hailed Liverpool midfielder Fabinho, saying that the 26-year-old has ‘built a positive growing’.
The former Monaco star has become an integral player for the Reds since joining them. So far, Fabinho has made 58 appearances for Liverpool with two goals and four assists to his name.

This season, the 26-year-old has been maintaining his good form for the Reds and even scored a screamer against Manchester City some days back. Fabinho’s performances for Liverpool has also seen him being included in Brazil’s squad for every international break in 2019/20 so far.
Tite hailed the defensive midfielder, saying that he has played well in the opportunities given to him. As quoted by Goal.com, the Brazil manager said: “Fabinho has built a positive growing. All the times he played, he played very well. And he brings confidence from his club to the Brazil national squad. In a natural way, and we can feel it. It’s not that you can only see it, you can feel it. Fabinho is playing his normal football in a role that he also has at Liverpool.”
Given his performances for Liverpool, there’s a good chance of the 26-year-old becoming a regular starter for Brazil soon. Fabinho came on as a second half substitute in the match against Argentina but there’s a chance Tite might start him in tomorrow’s match against South Korea in Abu Dhabi.

Zooko can voluntary cut his share from 0.9% to 0.1% for example. (that’s as much as the 34 others get). Pretty sure he is compensated enough by Tezos and the other projects he works on.

“Two monks took the blood of a duck, which they renewed every week; this they put into a phial, one side of which consisted of a thin, transparent crystal; the other thick and opaque; the dark side was shown until the sinner's gold was exhausted, when, presto! change, the blood appeared by turning the other side of the phial. Innumerable toe-parings, bones, pieces of skin, three heads of St. Ursula, and other anatomical relics of departed saints, were said to cure every disease known to man.” — Alfred Wesley Wishart, A Short History Of Monks And Monasteries
