a cross-platform, interpreted and object-oriented language. Yukihiro Matsumoto, commonly known as 'Matz' created the Ruby language in 1993. The year 2004 saw a massive surge of interest in Ruby, with the introduction of the Ruby on Rails Web application framework by David Heinemeier Hansson.

Ruby is a scripting language. There is no special main method in Ruby from which execution begins.
Parentheses are usually optional with a method call. These calls are all valid:
foobar
foobar()
foobar(a, b, c)
foobar a, b, c
In Ruby, everything from an integer to a string is considered to be an object (more on this later). And each object has built in 'methods' (Ruby term for functions) which can be used to do various useful things.
exclude: Some methods such as puts and gets are available everywhere and don't need to be associated with a specific object.
"kreeti".capitalize
=> "Kreeti"
>> 6.next
=> 7
>> false.class
=> FalseClass
Numbers without decimal points are called integers, and numbers with decimal points are usually called floating-point numbers or, more simply, floats.

Chart supports an unlimited number of labels that can be used to describe a chart and its components.
There are two types of labels: axis labels and data point labels. Axis labels are used along an axis, while data point labels are used to describe data points.
Automatic Creation
Labels by default are automatically created for an axis.
IIf data points do not provide an associated X axis label and custom labels are not being used, then X axis labels are created using the axis scale (see the figure below).
Data points can optionally specify an associated axis label via the AxisLabel property, and this label is then displayed along the X axis for that data point (wee the figure below).
Note that custom labels can also be used along an axis./p>
Automatic Sizing of Label Text
You can automatically adjust the size of the axis label text by setting the Axis.IsLabelAutoFit property to true. The Axis.LabelAutoFitStyles property then determines how autofitting occurs.
Depending on the Axis.LabelAutoFitStyles property, the axis label angle, font size, and offset are then automatically adjusted to fit the label text.
DateTime Support and Formatting
If an axis utilizes a DateTime interval type, then its axis labels are displayed as DateTime values. Both custom and standard .NET date/time formatting can be used.
Multiple Label Rows
Custom axis labels can be specified, and these custom labels are displayed using label rows (see the figure below):
Easy Positioning Using Interval Properties
In the Axis.LabelStyle property, the interval, interval offset, interval type and interval offset type properties determine how often an axis' labels are drawn.
Both the interval and offset can be DateTime values. Note that Sunday is considered the first day of the week. This is assignment is used to determine when positioning offsets. The figure below demonstrates an offset of one day and an interval of one week.
Use data point labels to describe specific data points. Specify text for the label using the DataPoint.Label property. You can also see the IsValueShownAsLabel property in a Series or DataPoint object to display the data point values as labels.
Note that you can use a line break for multi-line labels. At design time, use a '\n' character sequence. At run time, use your respective programming language's line break or carriage return expression. For example, vbCrLf for Visual Basic.
Keywords
You can use keywords in the DataPoint.Label property. These keywords are replaced with dynamically generated values into the data points' labels. The figure below demonstrates using the #VAL keyword.
Keywords are case-sensitive, and are specific to the chart element to which they are applied. For example, #VAL is used for series and data points. Refer to the following table for a listing of all available keywords:
Keyword/Th> Replaced By #VALX X value of the data point #VAL, #VALY, #VALY2, #VALY3, ... Y values of the data point #SER Series name #LABEL: Data point label #INDEX Data point index #PERCENT Percentage of the data point Y value #TOTAL Total of all Y values in the series #LEGENDTEXT Legend text SSmart Labels
When using data point labels for charts with a large data set, data point labels often collide. Smart labels helps overcome these issues by repositioning the labels based on a set of user-defined rules, which are available via the Series.SmartLabelStyle property. In the figures below, the chart on the left does not use smart labels, while the chart on the right uses smart labels.
DateTime Support and Formatting
Data point labels have the same DateTime formatting support as axis labels. Refer to the DateTime Support and Formatting section for axis labels.

Why use Woopsa?
- It makes you ready for the Industry 4.0 revolution.
- When simplicity also means power. Aside from reading/writing values and calling methods, Woopsa also supports multiple requests and the publish-subscribe pattern as native extensions. This makes polling a thing of the past, and allows you to communicate in real-time with very low bandwidth overhead. Because Woopsa shares so many concepts with OPC-UA, you can also use it as a gateway server to connect your webapps to OPC-UA servers.
- Get started in less than 5 minutes.
- Sure, you could roll out your own RESTful API, imagine which methods and data your application needs to expose and then write both the client — and server — side of your application. Save time by using Woopsa: you can immediately get properties and call methods on your model, with virtually zero effort.
- It's super simple stuff.
- Woopsa is an Internet of Things protocol that brings all the communication mechanisms you need for your connected applications : explore the model, read/write properties, invoke methods, publish/subscribe notifications and perform multiple requests at once.
All these services are implemented simply using JSON over HTTP, making it also usable in web browsers natively. Woopsa can also be used as a simpler protocol that answers the common needs of OPC-UA users, making it a viable open, free and simple alternative for many applications.


Troubleshooting¶
Milestone releases¶
When you clone the corda or cordapp-template repos, they will default to the master branch. The master branch is being continuously developed upon, and its features may not align with the state of Corda as described in the docs. Additionally, the master branch of the CorDapp template may break in response to changes in the main corda repo.
When developing on Corda, you should always check out the latest milestone (i.e. stable) branch instead. For example, to check out milestone 0, you’d run git checkout release-M0
.
Java issues¶
Outdated/non-Oracle JDKs¶
Many users have faced issues when running versions of Java that are either outdated, or are produced by organisations other than Oracle (e.g. OpenJDK). The errors generated by these issues will not always clearly point to the JDK as the cause. If in doubt, check your JDK version by following the instructions here. You can download the latest version of Oracle’s JDK here.
“Unresolved reference: javafx”¶
JavaFX is not bundled with OpenJDK. If you are using OpenJDK and get an ‘Unresolved reference: javafx’ error, this means that you need to install OpenJFX.
If you have APT installed and OpenJFX is part of your Unix distribution’s package list, you can do this by running sudo apt install openjfx
, and possibly sudo apt install libopenjfx-jav
. Other users will want to refer to the guide here, or to the list of Community Builds here.
IDEA issues¶
No source files are present¶
When opening a project in IDEA for the first time, you will need to build the project. You should see “Unlinked Gradle project?” in a pop-up window in the top-right corner or in a popup alert window. It will also appear in the “Event Log” window which can be opened by clicking on “Event Log” at the bottom right of the IDEA window. Find one of these links and click on “Import Gradle Project”.
Wait for it to download the dependencies. You may then see another popup titled “Unindexed remote maven repositories found.” This won’t affect Corda, so you can choose to leave them unindexed.
If still have problems, the JetBrains website has more information on here.
Run configurations are missing¶
If you opened the Corda project by clicking “Import Project” on the IDEA splash screen rather than clicking “Open”, a bug
in IDEA will cause it to wipe and recreate the .idea
directory where the run configurations are stored. The fix is
simple and doesn’t require you to re-import the project: just undelete the files! You can do that by either:
- Running
git checkout .idea/runConfigurations
to redownload the files. - Using the “Version Control” pane in IDEA to undelete the files via the GUI.
IDEA complains about lack of an SDK¶
If IDEA refuses to open a project because an SDK has not been selected, you may need to fix the project structure. Do this by following these instructions. The correct JDK is often found on a path such as jdk1.8.0_xx…/Contents/Home
. Ensure that you have the Project language level set at 8.
If you are having trouble selecting the correct JDK, the JetBrains website provides the following guidelines.
Kotlin plugin¶
There are two ways to configure Kotlin in IDEA:
- Via the initial project opening screen, by using the
Configure > Plugins
tab. - From an open IDEA project, by clicking
IDEA -> Preferences ...
(on OS X) orFile -> Settings
(on Windows). Select the Plugins bar to confirm that Kotlin is installed and up-to-date.
If you are still having trouble installing Kotlin, first try upgrading the Kotlin plugin. At the time of writing, you can identify the latest version of the Kotlin plugin on this page.

Lazy ordered list.
Usually, ordered single-linked list is used as a building block for the hash table implementation.
Source:
The lazy list is based on an optimistic locking scheme for inserts and removes, eliminating the need to use the equivalent of an atomically markable reference. It also has a novel wait-free membership find
operation that does not need to perform cleanup operations and is more efficient.
It is non-intrusive version of cds::intrusive::LazyList class
Template arguments:
GC
- garbage collector usedT
- type stored in the list. The type must be default- and copy-constructible.Traits
- type traits, default is lazy_list::type_traitsUnlike standard container, this implementation does not divide type T
into key and value part and may be used as main building block for hash set algorithms.
The key is a function (or a part) of type T
, and this function is specified by Traits::compare
functor or Traits::less
predicate
LazyKVList is a key-value version of lazy non-intrusive list that is closer to the C++ std library approach.
It is possible to declare option-based list with cds::container::lazy_list::make_traits metafunction istead of Traits
template argument. For example, the following traits-based declaration of gc::HP lazy list
is equivalent for the following option-based list
Template argument list Options
of cds::container::lazy_list::make_traits metafunction are:

The operation performs inserting or changing data with lock-free manner.
If the key
not found in the list, then the new item created from key
is inserted into the list. Otherwise, the functor func
is called with the item found. The functor Func
should be a function with signature:

Finds the key val
and performs an action with it.
The function searches an item with key equal to val
and calls the functor f
for the item found. The interface of Func
functor is:
where item
is the item found, val
is the find
function argument.
You may pass f
argument by reference using boost::ref
or cds::ref.
The functor may change non-key fields of item
. Note that the function is only guarantee that item
cannot be deleted during functor is executing. The function does not serialize simultaneous access to the list item
. If such access is possible you must provide your own synchronization schema to exclude unsafe item modifications.
The val
argument is non-const since it can be used as f
functor destination i.e., the functor may modify both arguments.
The function returns true
if val
is found, false
otherwise.

Inserts new node.
The function creates a node with copy of val
value and then inserts the node created into the list.
The type Q
should contain as minimum the complete key of the node. The object of value_type should be constructible from val
of type Q
. In trivial case, Q
is equal to value_type.
Returns true
if inserting successful, false
otherwise.

Inserts new node.
This function inserts new node with default-constructed value and then it calls func
functor with signature
The argument itemValue
of user-defined functor func
is the reference to the list's item inserted. User-defined functor func
should guarantee that during changing item's value no any other changes could be made on this list's item by concurrent threads. The user-defined functor can be passed by reference using boost::ref
and it is called only if the inserting is success.
The type Q
should contain the complete key of the node. The object of value_type should be constructible from key
of type Q
.
The function allows to split creating of new item into two part:
key
with initializing key-fields only;f
functorThis can be useful if complete initialization of object of value_type
is heavyweight and it is preferable that the initialization should be completed only if inserting is successful.

Returns list's item count.
The value returned depends on opt::item_counter option. For atomicity::empty_item_counter, this function always returns 0.
Warning: even if you use real item counter and it returns 0, this fact is not mean that the list is empty. To check list emptyness use empty() method.

Module: FriendlyId::History
- Defined in:
- lib/friendly_id/history.rb
Overview
History: Avoiding 404's When Slugs Change
FriendlyId's History module adds the ability to store a log of a model's slugs, so that when its friendly id changes, it's still possible to perform finds by the old id.
The primary use case for this is avoiding broken URLs.
Setup
In order to use this module, you must add a table to your database schema to store the slug records. FriendlyId provides a generator for this purpose:
rails generate friendly_id
rake db:migrate
This will add a table named friendly_id_slugs
, used by the
Slug model.
Considerations
This module is incompatible with the :scoped
module.
Because recording slug history requires creating additional database
records, this module has an impact on the performance of the associated
model's create
method.
Example
class Post < ActiveRecord::Base
extend FriendlyId
friendly_id :title, :use => :history
end
class PostsController < ApplicationController
before_filter :find_post
...
def find_post
@post = Post.find params[:id]
# If an old id or a numeric id was used to find the record, then
# the request path will not match the post_path, and we should do
# a 301 redirect that uses the current friendly id.
if request.path != post_path(@post)
return redirect_to @post, :status => :moved_permanently
end
end
end

Dropbox Passwords
I tend to pay for a lot of subscription services. In fact, my friend Mark and I have enough of them between us that we needed not one but two episodes of our podcast just to talk about all of our subscriptions.  It often feels trivial to tack on yet another thing that costs $5 - $10 a month, but over the course of the year it adds up.
Enter Dropbox Passwords, a password manager built into Dropbox. In the past I’ve used Dropbox to sync passwords in conjunction with KeePassX, so having the same functionality built directly into the platform seemed nice. The fact that it’s a feature included with my Dropbox Plus plan and would save me from paying $80 a year for my current password manager is also a nice bonus. First I just had to put it through its paces.
Migration⌗
Migrating to a new password manager is typically a fairly painless process. Every password manager I’ve ever used has given me the option to export my passwords to a variety of plaintext file formats. Naturally, having a plaintext file with all of your credentials is a terrible idea, but unless the machine you’re operating on is a digital cesspool it should be fine for the few minutes it takes to import the file somewhere else.
In my case, I exported a CSV and imported it into Dropbox Passwords. I initially got a message that there weren’t any accounts to import. I opened the CSV file and saw that some of the columns had weird headings and assumed Dropbox didn’t know what fields in the CSV mapped to which fields within Passwords. Their help documentation covers what’s needed:
The columns in your CSV file must be labeled so Dropbox Passwords knows how to import the information. Although Dropbox Passwords can recognize a range of labels, we recommend labeling them “Name”, “Password”, “Username”, “Notes”, and “URL”.
I updated the column headings to match the documentation above, and everything was fine.
Desktop Client⌗
The desktop client for Dropbox Passwords is spartan to say the least. You get fields for:
- Site Name
- Username
- Password
- URL
- Notes
That’s it. In other password managers, I frequently leverage either additional passwords or custom fields to add things like app passwords, API keys, etc. While I could store those in the free-form Notes field in Dropbox Passwords, the values aren’t masked out like they would be in other services with dedicated fields for this sort of thing.
After the initial setup where I logged in with my Dropbox credentials, the app gave me a “word list.” This PDF just had 12, random, English words on it. This serves as an extra security mechanism that I’ll touch on in the next section.
After the app was set up, it asked me to create a 6 digit PIN. That PIN is used to unlock the app if it times out due to inactivity. It’s worth noting that the browser extensions will not autofill login information is the application is currently locked; more on that later as well.
Mobile Apps⌗
There isn’t too much to say about the mobile apps; they’re basically exactly what you would expect. It is worth mentioning that, at the time of this writing, there’s no iPad version of the app, meaning I’m stuck looking at the blown-up iOS app. It’s not a huge ordeal, though, because aside from logging in initially I almost never open the app itself. Like every other password manager, iOS can be configured to automatically get passwords out of it without requiring an app switch. It also integrates with Face ID and Touch ID on iOS for quick unlocking.
Multi Factor Authentication⌗
Dropbox Passwords automatically implements a sort of MFA. When I logged in to the app on my phone, for example, it gave me a prompt on the desktop client. I had to accept the prompt there to confirm that I was, in fact, trying to configure the app on a phone. Likewise, when I configured the app on my iPad, I received a prompt on both my laptop and my phone.
This is where you might wonder what happens if I don’t have any of those other devices handy. In that case, I can use the word list to log in. I actually ended up doing this one time, and it worked without a hitch. What happens if I also lose the word list? Let’s hope I never find out. It’s nice to know, though, that despite the fact that the content is tied to a Dropbox account, Dropbox account credentials alone aren’t enough to access it.
Browser Extensions⌗
You might wonder why I talked about desktop and mobile clients, switched gears to authentication, and then came back to a “client.” The reason is that the browser extensions are literally just a wrapper that provides integration with the desktop app for things like autofilling credentials. For example, clicking on the Dropbox Passwords extension icon in Safari on macOS doesn’t even open a UI for the extension… it pops open the full Dropbox Passwords client. I see this frequently when nothing autofills in my browser, I click on the icon for the browser extension, and then it opens the full app where I see it requesting my PIN to unlock it.
The reason why wrapper browser extensions are noteworthy for me is that there are no standalone extensions or even direct web access. If Dropbox Passwords doesn’t have a client on your platform of choice, you’re simply out of luck. For example, I can’t access my passwords when using Manjaro Linux on my Pinebook Pro. I verified this by installing the browser extension; clicking on it will bring me to a lovely message that the application isn’t available for my platform.
Where this seems really insane to me is that if I log into my Dropbox account on the web I can see the vault for Dropbox Passwords! But clicking on it gives me the same screen as shown in the image above.
I can’t actually do anything to access it. Even just some kind of web portal like I can access with Bitwarden, LastPass, or 1Password would be better than nothing. I can definitely understand not making a native Linux app a priority, but not having a browser extension or web access in 2020 blows my mind more than a little.
I really hope this is something the Dropbox Passwords team is actively working on. While the overall service isn’t quite as slick or polished as some of its competitors, the fact that it comes included with paid Dropbox Plans is a huge boon; people like myself will have to think twice about paying extra money for a service they already have included with their existing Dropbox subscription. There are some hurdles to overcome for Dropbox Passwords to reach parity with its competitors, but for many people it’ll be good enough as-is.

This incredible breakfast of fried breaded eggs and mushrooms will certainly make an impression. Go on. It's Christmas.
For the deep-fried egg, bring a large saucepan of water to the boil, add the vinegar and a pinch of salt. Boil four of the eggs for 5½ minutes. Remove the eggs from the saucepan using a slotted spoon, and leave to chill in a bowl of iced water.
Whisk the remaining egg in a bowl with a pinch of salt and freshly ground black pepper.
Peel the boiled eggs. Prepare a shallow plate of flour and a separate plate of breadcrumbs. Dredge the boiled eggs in the flour, then dip into the beaten egg and roll in the breadcrumbs. Set aside on a tray in the fridge until needed.
Meanwhile for the truffle mayonnaise, place the egg yolks, white wine vinegar and mustard into a food processor and blend until pale and creamy.
With the motor running, pour in the oil, in a slow steady stream, until the mayonnaise is thick (you may not need all the oil). Mix in the lemon juice and truffle. Set aside in the fridge until needed.
For the wild mushrooms, heat a large frying pan over a medium heat, add half of the butter and fry the brioche croûtons until golden-brown on each side.
Drain onto kitchen paper then carefully stamp out a small hole with a 2.5cm/1in round cutter at one end of the croûton.
Place onto the serving plates.
Return the frying pan to the heat, add the remaining butter and the mushrooms and gently fry over a high heat for 2-3 minutes, or until just tender.
Season with salt and freshly ground black pepper, then stir in the chives.
To cook the eggs, heat the oil in a deep-fat fryer to 180C/350F. Alternatively, pour the oil into a deep, heavy-based pan to a depth of 2cm/¾in and bring to the same temperature on the hob, checking with a sugar thermometer. (CAUTION: hot oil can be dangerous. Do not leave unattended.)
Fry the eggs until golden-brown all over. Remove with a slotted spoon, drain on kitchen paper and season with salt.
To serve, carefully place each egg into the hole on each brioche croûton and take a slice off of the top to just show the yolk.
Pile the mushrooms onto the other end of the croûton, then spoon a little truffle mayonnaise directly in the middle in front of the croûton.

Holiday Gift Guide 2019: Blu-ray gifts for film fanatics
From a kaiju bonanza to the definitive assemblage of a decades-spanning TV classic, these are the Blu-ray gifts your friends and family will be very happy to receive this holiday season
by Norman WilnerBig Trouble In Little China: Steelbook, Lithograph and Green Vinyl Edition
It took a while, but John Carpenter has finally become the rock star he’s always wanted to be: his movies and scores are being rediscovered by a new audience, and that audience is heavily into collectibles. Shout Factory has been giving his films the special-edition treatment for a while now, finally rolling out his magnificently goofy kung-fu adventure Big Trouble In Little China this month in a jam-packed special edition – which is available from the label in a limited exclusive bundle with a vivid lithograph of the steelbook art and a 7” green vinyl single of the re-recorded main title theme, because what the hell.
$51.98 (USD), Blu-ray, shoutfactory.com
Godzilla: The Showa Era Films, 1954 - 1975
The Criterion Collection’s admiration for the King Of The Monsters goes back a long, long way; the highbrow label had been negotiating a box set of Toho’s seminal monster movies back in their laserdisc days. It was worth the wait: Criterion’s glorious, oversized package is a celebration of kaiju cool, assembling 15 features on eight discs with copious special features – including the original Japanese cut of King Kong Vs. Godzilla, never before available to western audiences – and commentaries. Also, you can put it on the shelf next to last year’s Ingmar Bergman box to see if they fight.
$209.98, Blu-ray, unobstructedview.com
Ida Lupino Filmmaker Collection
People don’t talk enough about Ida Lupino, even after a comprehensive TIFF retrospective a couple of years back and a growing sense that the actor-turned-filmmaker was one of the most interesting talents to come out of the Hollywood studio system, bringing a woman’s perspective to film noir. Kino Lorber’s boxed set aims to fix that, offering new restorations of four of Lupino’s features – Not Wanted, Never Fear, The Hitch-Hiker and The Bigamist – all supplemented with audio commentaries (by women!) and a glossy booklet reprinting a 1980 essay by the late Ronnie Scheib. Sadly missing is Lupino’s shattering 1950 drama Outrage, which remains unavailable in North America, but hopefully that’ll be available by next Christmas.
$87.98, Blu-ray, unobstructedview.com
The Anne Bancroft Collection
Ida Lupino’s not the only woman getting her own boxed set this year. Mixing previously released titles (Don’t Bother To Knock, The Miracle Worker, The Graduate, To Be Or Not To Be and her sole effort as a writer-director, Fatso) with new-to-Blu editions of The Pumpkin Eater, Norman Jewison’s Agnes Of God and David Jones’s 84 Charing Cross Road, Shout Select’s eight-disc omnibus spans 35 years in the beloved Bancroft’s career – and serves as a reminder of her versatility and her enduring intelligence. Buy it for that relative who’s been moaning that they don’t make movies like they used to.
$79.98, Blu-ray, Bay Street Video (1172 Bay) and Sonic Boom (215 Spadina). Available December 10.
The Fly Collection
Let’s be honest: only one of the Fly movies is any good, and it’s the one David Cronenberg made in 1986 with Jeff Goldblum and Geena Davis. And it’s not just good, it’s great. But 20th Century Fox made three Fly movies before that, and there’s Chris Walas’s disappointing The Fly II on the other side, so clearly there’s something about the whole human-insect hybridization thing that resonates and you probably have a weird friend who would really like to have this spanking-new Scream Factory set on his shelf.
$79.98, Blu-ray, Bay Street Video (1172 Bay) and Sonic Boom (215 Spadina). Available December 10.
POPSTAR: Never Stop Never Stopping Steelbook
Shout Factory’s reissue of Popstar: Never Stop Never Stopping doesn’t really add anything to The Lonely Island’s genius musical mockumentary – all the special features, including the killer audio commentary from creator/stars Andy Samberg, Jorma Taccone and Akiva Schaffer – were produced for Universal’s original 2016 disc – but it does enclose its Blu-ray in a gorgeous, ridiculous steelbook case featuring Conner4Real torching a giant bee with a flamethrower. It’s a gift for the ages, especially if you start singing the Michael Bolton hook from Incredible Thoughts while the recipient unwraps the package.
$29.98, Blu-ray, Bay Street Video (1172 Bay) and Sonic Boom (215 Spadina).
Twin Peaks: From Z To A
You might want to check to make sure the David Lynch enthusiast in your life hasn’t already pre-order CBS/Paramount’s comprehensive Blu-ray box – limited to just 25,000 pieces – includes all three seasons of the cult television series and Lynch’s 1992 prequel Fire Walk With Me, as well as a 4K disc that presents the series pilot and The Return’s stunning eighth episode (the one with the woodsman) in ultra high-def. Also included are most of the special features produced for previous releases (including the trove of deleted scenes known as The Missing Pieces), a new interview with Kyle MacLachlan and Sheryl Lee, a selection of art cards and a little figure of Laura Palmer kissing Agent Cooper in the Red Room.
$170, Blu-ray/4K, Bay Street Video (1172 Bay) and Sonic Boom (215 Spadina). Available December 10.
Anna And The Apocalypse
Looking for a great new holiday tradition? Here’s a Christmas movie where the dead walk and the living sing, forcing a teenager (Ella Hunt) and a few of her classmates to form a rescue party and save their friends (and her custodian father) who’ve barricaded themselves in the school. With or without the soundtrack CD, it’s a perfect stocking stuffer – and we’re not just saying that because VVS pull-quoted NOW’s review for the box art. Honestly.
$32.99, Blu-ray, Bay Street Video (1172 Bay) and Sonic Boom (215 Spadina)

It's interactive and colourful features will add fun into learning Mathematics, as they are able to learn different shapes and their names, number of sides and faces etc. in a hands on and creative way.
These primary ages students will also likely be familiar with web applications such as Google Draw and Photoshop, so they will be able to interact with the features of my program easily.
See below, Google Draw, an web drawing application which I used as inspiration when designing my own.
Overall planning of versions
Project backlog
I used project management tools and techniques to plan the program's development. One example of this is using a project backlog to prioritise stages of work.
Sprint One: Minimum product
My aim in this Version, is to create a minimum product; a program that draws (click and drag) one shape on the canvas.
Plan
Boards
This was part of the Agile based method where I broke down the development process into smaller sprints, planned these through kanban boards and then executed the new feature.

Errors I found through testing:
I tested the program's new functions in the main proram each time. This way I could use information gained from testing to improve the program's functionality.

Sprint Two: Drawing Page
Create a drawing page/area on the canvas which will register when the mouse is clicked to draw shapes.

Test with errors:
First problem:
Breakdown of iterative process to fix the error, video of the error and fix
This is one example of testing revealing an error, and shows the importance of trialling each new component.
When considering a fix for this problem, I trialled two alternative approaches to fixing the problem, and selected the most suitable one.
I effectively used what I learnt from testing and trialling to improve the functionality of the outcome. I found a solution where objects draw outside of the drawing area (inspite of having the boundary inside parameters).
I decided to use the clip function as my solution.
Second Problem:
Third Problem:
When the mouse is dragged outside of the drawing page, and then also beyond the canvas space, the shape doesn't draw/get placed once they reenter.
Possible solution: as soon as the mouse leaves the canvas, it acts as if mouseUp, and the shape is placed (even if shape appears cut off).
Final working test of Version 2:
Reflect
In this sprint, I began to refine my, develop to test to finalise, planning structure. By the end of the second sprint, I had repeated this developement process a few times, which gave me a much clearer idea of the possibilities of what I can achieve.
This meant that my aims for future sprints were much more refined and realistic - stepping up incrementally and not making too large a jump right away. For example, I decided that Sprint 3 will be exploring Buttons, rather than jumping straight into creating more advanced shapes such as an ellipse. Having a button will give much more freedom during my testing and development, as I can use my mouse without place a rectangle everywhere I click.
Overall it was really beneficial to see my program in a highly simplified form (Sprint 1) as I could build on this potentially shippable product. I decided the logical next step for Sprint Two was to create a drawing page, and I will now be able to use Agile's sprint development process, to incrementally build on the basics I now have.
Sprint Three: Rectangle and Ellipse buttons
Introducing a simple two buttons assigning whether to draw a rectangle or ellipse shape. These buttons are clickable as they are on the canvas but outside of the drawing page.
Plan
Standup
I carried out this project using an Agile based method where I broke the development process into smaller segments called 'Sprints'. I planned each one using Kanban boards, and used the technique of a few 'Standups' to ensure I was tracking along well, and plan out what I learnt from previous sprints, errors that need fixing, and my next steps.
This was an important part of reviewing, and then moving onto my next sprint.

Test
3.1
Initial test to show basic buttons appearing:
3.2
Test of making an ellipse appear on the drawing page:
3.3
Test to show ellipse + bounding box being drawn instead of the rectangle that was drawn in Version2:
3.4
Pseudo code:
if (Button.shape == "Rectangle"){
var temp = new Rectangle(this.xMouseStart, this.yMouseStart,this.w,this.h,"rgb(10,60,120" )
}
else if (Button.shape == "Ellipse"){
var temp = new Ellipse(this.xMouseStart, this.yMouseStart,this.w,this.h,"rgb(10,60,120" )
}
// add new rectangle to the object list
this.objectSet.push(temp);
}
Button.clicked = ""
Button.shape = ""
Final test showing the program working:
Reflect:
Problem found when testing:
When I tested my program, I found the program crashed if the user tried to click in the drawing page without selecting a button first. It only continuing working if the user selected Rect or Ellipse button and then tried to draw in the page.
This is a major design error, as when a user first goes on a webpage, particularly young kids who are my expected users for this Maths drawing application, they often click around first to familiarise themselves with the page - and I wouldn't want my application to crash in this event.
Solution:
I created this loop around the object set being pushed, so it only gets pushed once there is something to be pushed (eg. when temp exists).
This error made me consider my future step, which is to be able to unselect buttons after you have clicked on them.
Sprint Four: Colour management
Create a colour grid (made up of swatches) on the canvas area (where the buttons are) outside of the drawing page. The user can select a colour from the grid, the state of the swatch is communicated by a stroke change, and then the next shape will be drawn in this colour.
Plan
Stand up 9th June:
Boards
Link to the canvas page
Test
Final test to show swatches working:
Reflect
This is one example of trialling and decision making in the program development. I explored different design options of where to create my swatch class when creating the colour grid. Below explains how I decided which solution was the best option.
By considering different design options, I improved the format of my code, and in this case, how compact the program is by avoiding too many new files.
Problem I found during testing:
To reflect which button has been selected I changed the stroke thickness of the box's outline. However I noticed that the first button selected, doesn't appear as unselected, until the second button is clicked on, and then the mouse is moved.
The mouse having to move before the prior button appearing unselected, was due to where I placed my code to change stroke_outline.
Video to show problem:
Stroke outline in Mouse Move:
Video to show problem solved:
Stroke outline in Update:
This shows a further example of trialling and decision making as I explored different options of where to put my stroke outline width change when clicked on.
I trialled the first option at first, and effectively used the information I learnt from this test, to improve the functionality of my outcome, as by moving the location of this stroke outline condition statement, the previously clicked button can now become unclicked.
Sprint Four PART TWO: Creating a colour grid
Now that I have created and tested two working swatches, I want to form a colour grid of these swatches.
Firstly I ran through my colour array, through console logging.
VIdeo showing working colour grid:
Sprint Five: Polygon
My aim in this Version is to create a button which when selected draws a polygon. The type of polygon is determined by user entry of number of sides.
Plan
As I mentioned in 'Future Steps' under "Simplify?" at the bottom of this plan, I looked into ways to avoid too much repeated code. I was finding at this point, that much of the code for new functions or buttons etc. was repeated from other functions.
This led me to question how this could be mitigated, and I added this to my project backlog.

Final working test of Sprint 5
Reflect
In the future, I will add a text insert/heading above my sub-buttons to explain what they do. This will help my user to interact with the program more easily.
I also noticed that even before I had selected a sub-button (to select the num of sides the polygon will have), my program allows the user to draw a deafult polygon.
This is definitely better for usability, than if the polygon isn't drawn until you select a sub-button, however I think my communication with the user could be clearer. Through testing I found that
the default polygon that is drawn is a pentagon, and so I made a change so that the sub-button for 5 is shown to be 'selected' (colour scheme, outline width etc.) right from when the application is opened, in order to inform the user what default polygon will be drawn. This might also help their understanding of what the sub-buttons do.
I then made sure I created this same setClicked() function, for any future sets of sub-buttons which had a default choice selected (eg. for star num of points, and for size of brush stroke).
Sprint Six: Star
My aim in this Version is to create a star function to create a star drawing option. Button to create a star on the canvas, with side buttons to determine the number of points of the star.
Plan
Boards
Link to the canvas page
Test
What I learnt about the design process was that building a new feature incrementally is really important.
The first part of testing the star, was to simply create a star class, and create a simple variable in the main to test it appears on the canvas.
Then, firstly I would create a new button for 'star' and test it, then link pushing the new star with when the button was selected.
Finally I could create and test a set of sub-buttons for the number of points it would have, and then link the different shaped stars to this set of sub-buttons.
Reflect
When I was testing this sprint, I found that the drawing page quickly got very full and distracting. This prompted me to consider a clear and/or undo button, which I will address in my next sprint.
This will improve my testing process, as I can test my new shape additions comprehensively without filling up the drawing page as quickly.
Sprint Seven: Clear and Undo
My aim in this Version is to create clear and undo buttons on the canvas; enabling the most recent shape added to be removed, or the whole drawing page to be cleared of shapes.
Plan
Boards
Link to the canvas page
Final working test of Sprint 7
Reflect
As mentioned in my Sprint 7 plan, these new features will speed up my testing process in future versions.
In the future I would hope to create a redo button.
Through testing the undo button, I also started to consider how else I could adapt individual shapes that had already been added to the drawing page.
Something that would be interesting to investigate in future versions is being able to click on an individual shape and change it's colour or number of sides/points.
Sprint Eight: Brush
My aim in this Version is to create a brush feature + button. This allows the user to create a brush stroke line, which follows their mouse movement.
Plan
Boards
Link to the canvas page
Testing
The first part of testing the brush, was to create a dot class, loop these dots to form a stroke when the mouse clicked down, and to test it appears on the canvas.
Then I created three buttons (for 3 different brush stroke widths) and tested that they appeared on the canvas too. I also tested that when they were clicked on, they physically appeared 'selected' by changing colour and stroke width, to inform the user of their state change.
After these two tests I could integrate the two together.
Final working test of Sprint 8
Errors I found through testing:
Reflect
Now this new brush feature has been added, I plan to reorder the layout of my web interface. I will rearrange and resize some of the buttons so it is even more clear to the user what all the buttons do, and how they should interact with the application!
I also plan to adapt the colour scheme so it is more appealing to the eye - although I will keep it colourful as my target users are primary aged kids and I want them to engage with the Maths program as much as possible, to best help their learning.
I will also reflect more on my original purpose for the application and add features to aid Maths learning. One example is printing the names of the different polygons, and number of points on the star, when these shapes appear on the drawing page.
Sprint Nine: Spinning/animated ellipse
My aim in this version is to create an animated ellipse feature and button. This allows the user to create an ellipse that is rotating when placed in the drawing page.
Plan
Boards
Link to the canvas page
Testing
After creating the new Spinning Ellipse function, I called the class in my main file and updated/pushed the new variable. This was to test there were no errors creating a rotating/animated ellipse on the canvas.
Then I created a button to draw a spinning ellipse on the drawing page. I tested this new feature thoroughly, by using the swatch, dragging different sizes, dragging outside of the drawing page boundaries etc.
Reflect
In future versions my interactive web application to aid primary aged students with their understanding of Maths, I could consider adding more interactive features such as this one.
This is because it will draw young children's attention and make the program more fun to interact with.
An example of this is creating functions and buttons for 'Spinning Rectangle', 'Spinning Polygon', Spinning Star' etc.
Ideally I would want to develop a feature which could animate/begin rotating objects after they have been added to the drawing page. Or one singular button which could be clicked after selecting the shape you want, and then it will be an animated version.
Summary
I put all of my code through an online Javascript validator - 'beautifytools.com'. This ensured that my code was formatted properly, caught any final errors, and adhered to all javascript standards.
I reformatted the appearance of my web application to make it more appealing to the eye and intuitive for the user to follow. I designed the canvas area that contains the application (the graphical user interface) simply and minimalist, and I was thoughtful in my placement of buttons, subbuttons etc., to allow the user to intuitively use the application.
I commented all of my code so that the code is easier to follow and for the programmer (or any other experienced programmer) to find specific parts and adapt/improve the web application in the future. I also added general commenting throughout and comments defining the variables within the constructors for my main functions, so that it is obvious what each new function/section of code does. I then removed all console logs except for the ones that show that each file has been called, as they are not needed anymore, and might slow down the speed of my application working.
Finally I carried out some real user scenario testing with my family members, to try to catch any final errors that a user may make. This further improved my confidence that my program is intuative, fun for the user, and will not crash when in use.
User test with my sister of the final program:
This is an example of user scenario testing, as getting a non-programmer to try to use my program, tests unexpected input/user actions. This exposes any problems and other limitations which my previous, expected user behaviour testing might not have revealed.
Final design of my program, with added headings to show the user what the subbuttons do, based on feedback and confusion from user testing. This ensures my final design is very intuitive and user-friendly. I effectively used information from testing and trialling to improve the functionailty of the outcome.The interface was designed so that it was easy to use, and the colour and border width indications were made to make the selected buttons more obvious.
Relevant Implications Summary
Future Proofing
Describe:
This relevant implication considers whether or not it is easy to update and add new features to the program. A well ‘Future Proofed’ program means it is designed so that new features can be added and updated easily.
Address:
The main way I addressed Future Proofing, was by using precise and informative commenting (and commenting which served the purpose of a docstring by defining the function of all the variables in my constructors) to describe the purpose of all my functions and sections of code. This makes it easier for another programmer to quickly be ‘onboarded’ to my project and understand my design decisions.
I also addressed this implication by looping the buttons in my main. This means that a new button can easily be added every time that a new feature/shape is added to the program, with little code changes. I discovered this as I’ve been adding new features throughout the program and building the application incrementally. This ‘sprint’ process and the way I’ve designed the programme addressed ‘Future Proofing’. My program has a modular structure (objects) which allows easy extension of the program, as you can add a new feature by adding a new function (and therefore a new sprint). The function based structure of my program also means that changes and new features can easily be integrated into the main program - as a new function can be tested in a testing file first, then integrated smoothly.
I further addressed this implication, by programming all elements (colours, shapes and buttons) as objects. Each object therefore has code independent of others, and it takes a defined set of parameters to work. Most of these new objects require information about the basic mouse position, whether it’s inside the drawing page boundary, and the swatch colour that has been selected. I addressed Future Proofing as all of these objects have a similar structure and an update function. They are all called by update() and that is how they appear on the web application. The control object page (drawing page) is a central area where all of these objects are managed. Any programmer could receive my web application, and interpret my formatting to build on, remove and add their own new objects following my management process.
Functionality
Describe:
A functional program works well and loads quickly. This relevant implication ensures that the program is free from bugs or glitches and does not crash. The program should also be able to work and appear properly on different browsers and devices, and all the links should work correctly.
Address:
I addressed this implication by programming in mainly javascript. This means that the file size is low, and only consists of one main graphic - allowing my program to run and load quickly. I could observe the ‘load speed’ during my testing of each new sprint. This testing was all carried out through Visual Studio Code’s live web server where I stored my versions.
I addressed this implication through regular testing. I used a systematic sprint system from 'Agile' to ensure my program was flexible and robust. By decomposing the outcome into smaller components and using a function by function build, I could systematically test the program after every sprint (a new sprint for every additional function/feature). I tested each function for each new shape, by pushing as a new variable in the main.js, to ensure it appeared properly on the canvas first. This meant that any new components were tested prior to being integrated into the main program. Then I tested again after integrating into the main program with its corresponding button etc. This ensured that my program was functional and that I found any bugs or potential crashes in a step-by-step iterative building process. Each sprint I also used console logging when an error occured to find the root of the problem, and also to analyze boundary test functions etc.
I further addressed Functionality, by executing ‘user interaction’ tests, by asking family members and friends to test using my program, and asked them for advice around making the user experience more self-explanatory/easy to follow. When carrying out extensive testing of my program’s Functionality myself, I also tested by clicking in multiple positions around the canvas (in and out of the drawing page etc.) and dragging in different directions.
One example of testing helping me to develop the functionality of my program, is when drawing circular shapes such as an ellipse, the shapes often failed. I found this was because these objects were being given negative values for their radius, and so included the Math.abs function to make the radius positive regardless, and avoid any program crashes.
Usability
Describe:
This implication is about ensuring the program is easy to use. Usability is about helping and ensuring the user can recognise, diagnose and recover from errors. Usability ensures the user can not only avoid errors, but that the program can also correct errors without impacting the user. Usability also includes being able to restore to a previous state. This implication ensures the program follows usability heuristics, uses recognised conventions and matches the real world.
Address:
I addressed this implication by creating a simple web interface for my program. I tried to format the canvas page so that interaction was logical for the user eg. buttons having appropriate headings and their size reflecting their purpose (for example sub buttons being square rather than rectangular and located next to the correlated core shape buttons). I addressed the usability heuristic of ‘Visibility of System Status’ by communicating the current state of the program to the user at several points. Buttons physically reflect their change of state (change colour and border width when selected) and have hover colours so the user can clearly see what they are interacting with, and makes the next step, selecting a button, obvious.
I further addressed Usability by creating a draw guide, when the user drags on the drawing page to create a shape. This ensures that my program meets the usability heuristic of ‘Visibility of System Status’ as this guide communicates the size that the shape will be if they place it at that point. I also included ‘Undo’ and ‘Clear’ buttons which helps the user to recover from mistakes, as they can return to their previous place in the program. The ‘Clear’ button returning them to the original and blank state of the drawing page, is a recognised convention and matches the real world idea of ‘clearing’ a canvas/whiteboard etc.
Finally I addressed this implication by uploading updated versions of my files via the terminal, and using Github to manage my files. Github allows the programmer to restore a previous state of their program during the design process. This was a version control tool I used, as through Git I could revert to a previous state in the program's history.
Development Process: Git commits
I uploaded all of my files to Github to store my sprints as I built the program incrementally along the way. After each sprint I carried out regular commits on git, and backing up to the remote repository. This meant that I could use my commit history as evidence of versions.
This allowed me to progressively build up the complexity of the program. Periodically pushing each version of my program to my git-hub account and storing them in the repository that has an associated IP address, was very helpful.
I pushed these up to Github using the terminal. Here is evidence of my git commit history:
Project backlog and potential future additions:
Overall these processes (sprinting, kanban, prioritising, backlogging, planning) made a meaningful contribution to the planning process and final outcome.
My program management methods, version control system and trialling and testing processes highlighted ways which my program worked, but not well, and encouraged me to consider how to improve it's functionality. My final outcome is much better due to these processes, and enabled me to resolve any crashes along the way, more easily.

is locked to the input signal frequency because control theory states that
to control a process you will certainly have a finite and constant error so we
will use advantage of control theory of outputting constant error by doing this trick
if we want to control frequency of output wave and make it equal to input wave so we cannot do
that control operation direct we will try to control phase of the output signal phase \(\phi_{out}\)
and make it equal to input signal phase \(\phi_{in}\) by that we will have constant frequency as explained
in equations below (this principle is very huge as it lead us use the same theory but having zero error)
for example if want to make acceleration of car as the setpoint we need to control its velocity
PLL is like above loop but instead of making Vout traces Vin it make phi out traces Phi
like in figure below but we merged the summer with transducer
by a block named by phase shift detector(this is the right name) not the one in the figure below
because we are sensing the difference between phases not the actual phase
while loop filter is the controller and VCO is the target system
Opamp with finite Gain A0 and a feedback circuit using Passive components (R,L,C)
$$V_{out}=A_{OL}(V_{in}-V_{fb})=A_{OL}(V_{in}-\beta V_{out})$$ $$A_{CL}={V_{out} \over V_{in} }= {A_{OL} \over {1+\beta A_{OL}}}={A_{OL} \over {1+LG}}=>{1 \over \beta}$$ $$V_{err}=V_{in}-V_{fb}=V_{in}-\beta V_{out} = V_{in}-\beta A_{OL} V_{err}$$ $$V_{err}={V_{in} \over {1+\beta A_{OL}}}={V_{in} \over {1+LG}}=>0$$ $$LG=LoopGain$$We can express phase as a linear function of time because its derivative is the angular frequency of sine wave which is usually constant so that we can express the change of phase between two signals by \(\Delta \phi\), in the following way: \(x_1(t)=V_1sin(wt+\lambda_1)=V_1sin(\phi_1(t))\) and \(x_2(t)=V_2sin(wt+\lambda_2)=V_2sin(\phi_2(t))\) $$\omega={d\phi_1 \over dt}={d\phi_2 \over dt}=constant$$ $$\phi_1(t)=wt+\lambda_1, \phi_2(t)=wt+\lambda_2 $$ then we can plot them as two lines as in figure below
if we make \(\lambda_1 = \lambda_2=\lambda\) but with two different angular frequencies \(\omega_1 , \omega_2\)
then we will have two lines with two different slopes but with same interception on y-axis we made \(\lambda=0\)
in figure below
where also we can express frequency shift keying modulation like in figure below we have two slopes one for \(+ve\Delta f\) and one for \(-ve\Delta f\)
We control output frequency using a gain of \(K\) and \(V_{control}\) where it controls output frequency by the change in input voltage
$$\omega_{out}=\omega_o + K_{VCO}.V_{control}$$ $$\omega_o \space is \space the \space free \space running \space frequency$$ $$K_{VCO} \space is \space the \space gain \space of \space VCO [(rad/sec.)/V][Frequency/Voltage]$$we implemented phase detector using xor gate but its disadvantage works only for digital signal and second thing is that we have not to increase phase shift than pi or decrease it than zero because that will make phase difference become less than zero which will convert feedback to positive feedback so we work at phase difference of pi/2 but how pll works if we have error because we are targetting to have a constant phase error which leads to zero frequency error
$$\phi_1,\phi_2 ====>Phase Shift Detector(Differential Sensor)====>\Delta V$$Loop filter is a low pass filter which integrates on AC signal to get DC voltage signal for controlling VCO
$$\Delta V_{controlDC}=\int \Delta V_{ControlAC} dt ==VCO==> \Delta Frequency=\int \Delta \phi_{phaseshift} dt$$ $$Current \space in \space Branch \space R =I={{V_{in}-V_{out}}\over {R}}$$ $$V_{out}={Q \over c}={{\int I dt} \over c}=\int{{{V_{in}-V_{out} }\over {RC}}dt}$$Assume \(V_{controlAC}\) is \(V_m sin(\omega_mt)\) $$\Delta V_{controlDC}=\int \Delta V_{ControlAC} dt ,then,$$ $$V_{out}(t)=V_ocos(\omega_ot+K_{VCO}\int V_{controlAC}dt)=V_ocos(\omega_ot+K_{VCO}{V_m \over \omega_m}sin(\omega_mt))$$ if we decrease \(K_{VCO}\) we will have small ripples but \(\phi_e\) will increase so that there is a design trade off between both of them
Building a digital counter in the form of sequence of flipflops
PLL reached steady state means that phase difference between input and output became constant
\(\phi_{error}=\phi_{in}-\phi_{out}=constant\) which leads to \(\omega_{in}=\omega_{out}\)
phase error must be inversely proportional with loop-gain
width of VPD determines how much is phase difference which also indicates how much we decrease/increase VCO in order to control Vout lpf acts as integrator so when VPD width increases its value increases which increases VCO precedingly and vice versa
after antenna we have a bandpass filter to select a whole band not a channel like in case of a GSM like 800Mhz, 900Mhz, 1800Mhz, 1900Mhz and there are channels inside each band where each channel inside band is of width 200KHz, incase of GSM900 Standard, bandwidth of 5G is 1GHz because of large datarate incase of selecting channels(200KHz) then \(Q={900MHz \over 200KHz}=4500\) which is very and not possible thats why we don't select channel at once we select band of channels(25MHz) like \(Q={900MHz \over 25MHz}=36\) which is attainable in fact making a very sharp filter like of Q=4500 is achievable using passive filter but the bad thing about it that it will not be programmable thats why we said it is not possible
We have an low noise amplifier to increase signal to noise ratio in order to reject noise then we use the mixer to demodulate the channel to a lower frequency, local oscillator as it will be changed locally inside the receiver to make it centered at baseband then we use a lowpass filter at base band to select the required channel then we use a variable gain amplifier after the Low pass filter but it isnot drawn in the figure because if the input signal is amplified with a constant factor it will saturate adc after the dotted block is a digital processing like what we studied in DSP course, while inside dotted block is analog processing. Our main interest now is in PLL which is used to generate local oscillator (coherence receiver\Voltage controlled oscillator)
