San Francisco 49ers' Chase McLaughlin shanks potential game-winning field goal into the tunnel
by Ryan GaydosSan Francisco 49ers kicker Chase McLaughlin went from hero to zero during Monday night’s loss to the Seattle Seahawks, which ruined the 49ers' chances at an undefeated season.
McLaughlin tied the game in the fourth quarter to force overtime.
SEAHAWKS KNOCK 49ERS FROM UNBEATEN RANKS WITH 27-24 OT WIN
But when he had a chance to give the 49ers a win in overtime, his kick attempt went way wrong.
McLaughlin shanked the potential game-winning kick left. NBC Sports Bay Area reporter Jennifer Lee Chan posted a video of where the ball actually ended up.
FORMER LIONS, SPARTANS WIDE RECEIVER CHARLES ROGERS DEAD AT 38
The rookie out of Illinois was then mocked on social media for the attempt.
The Seahawks then drove down the field and won the game on a 42-yard Jason Meyers field goal.

McLaughlin was replacing the injured Robbie Gould. The 49ers were his second team this season. He started the year with the Los Angeles Chargers before being waived.

Hash, Hash ... Array!!!!
What's Hash & What's Array in Ruby
07/27/15
Ok, so what are these things hashes and arrays? Well, it’s storing and accessing data. Think of any program, in order for it to do anything, it needs to remember pieces of info and be able to retrieve them to do whatever you need it to do.
An array is a list. Think of a list of chores for example:
CHORES TODAY: 1) go to the bank 2) finish homework 3) lunch with Sophie
We give this array a name: chores_today[] . In this list we have three items but the crucial thing to know is that arrays start counting from 0 so ‘go to the bank’ is actually item number 0. We can call this item in the array by typing chores_today[0] . Similarly if we wanted to retrieve our lunch plans, we type chores_today[2]. How do we write this you ask? Well here it is:
chores_today = [ “go to the bank”, “finish homework”, “lunch with Sophie”]
As you can see, an array can hold anything really, integers, floats, strings.
Alright, so we know an array is a list, what’s hash? Think of hash being a list that you give to a friend to run your chores who needs to know more specific information like which bank? What homework?
chores_today = { "go to the bank" => "Wells Fargo", "finish homework" => "DevBootcamp", "lunch with Sophie" => "Mission Beach Cafe" }
To retrieve information from Arrays we use it’s position in the list. With hashes, we use the “key” instead. For example to retrieve “Wells Fargo” we type in chores_today[“go to the bank”] the key in this instant is “go to the bank”
Voila! Now you know, go give your girlfriend a shopping list in arrays and hashes!

See: Description
| Interface | Description |
|---|---|
| Callback |
Callback processes various events of the Java Simon API and is used as an extension point of the API.
|
| CompositeCallback |
Composite
Callback can hold more callbacks which allows to form callback trees where events are passed to
sub-callbacks. |
| FilterCallback |
FilterCallback extends
Callback adding filtering capabilities. |
| Class | Description |
|---|---|
| CallbackSkeleton |
Implements
Callback interface so that it does nothing - intended for extension by simple (non-composite)
callbacks. |
| CompositeCallbackImpl |
Composite callbacks holds child-callbacks and delegates any operations to all of them.
|
| CompositeFilterCallback |
This callback combines Composite and Filter behavior.
|
| FilterRule |
Represents filtering rule that checks whether sub-callbacks will get the event.
|
| Enum | Description |
|---|---|
| Callback.Event |
Enumeration of all supported callback actions.
|
| FilterRule.Type |
Enumeration of rule types that determines the evaluation of multiple rules in a chain.
|
Callback
is an event listener registered with the Manager
,
listening for manager or Simon events. Any number of callbacks can be registered on a manager using
Manager.callback()
and CompositeCallback.addCallback(Callback)
.
Non-composite callbacks are used to perform expected actions for particular events.
CallbackSkeleton
can be extended if only selected events are desired to be
implemented instead of implementating the whole Callback
interface.
Composite callbacks are used to organize other callbacks in trees and then to delegate all events to them. It is not recommended to mix composite callbacks with functionality, generally it should not be necessary to implement composite callbacks in addition to the following two provided implementations:
CompositeCallbackImpl
delegates all events to all sub-callbacks
(used in EnabledManager
for instance);CompositeFilterCallback
allows to filter events that should be propagated to the sub-callbacks,
filter rules can be added using
FilterCallback.addRule(org.javasimon.callback.FilterRule.Type, String, String, org.javasimon.callback.Callback.Event...)

a RESTful API wrapper for TinyURL
TinyURL API, https://tinyurl.com/api-create.php?url=<url-to-shorten>
will be blocked on a normal fetch() or XMLHttpRequest() command because of Cross-Origin Resource Sharing (CORS) policy. This is a RESTful API built on top of the old TinyURL api and will allow you to use TinyURL url shortener using fetch() or XMLHttpRequest() methods.
API URL
https://tinyurl-rest-wrapper.herokuapp.com/shorten?url=<url-to-shorten>
Example usage using fetch()
let url = "https://www.google.com" //url to shorten fetch(`https://tinyurl-rest-wrapper.herokuapp.com/shorten?url=${encodeURIComponent(url)}`) //encode url using encodeURIComponent() to avoid any possible errors .then(response => response.json()) .then(json => console.log(json))
If you're planning on using this api for your app and expects high usage traffic, please fork this repo and deploy your very own api. This api is deployed using Heroku and is using the free version. The server can only handle minimal concurrent requests and have a very small compute power. Here's a very good tutorial on deploying the wrapper api in Heroku. You can also deploy this on Google Cloud Platform (GCP), Microsoft Azure, Amazon Web Services (AWS), or in your own server.

Population growth
Recently I came across the following quantitative question:
A mythical city contains \(100,000\) monogamously married couples but no children. Each family wishes to “continue the male line”, but they do not wish to overpopulate. So, each family has one baby per annum until the arrival of the first boy. For example, if (at some future date) a family has five children, then it must be either that they are all girls, and another child is planned, or that there are four girls and one boy, and no more children are planned. Assume that the children are equally likely to be born male or female. Let \(p(t)\) be the percentage of children that are male at the end of year \(t\). How is this percentage expected to evolve through time?
At this point, the ambitious reader should not avoid spoilers and take a few minutes to try to solve it without using a piece of paper for calculations (ideally). If you do any mathematics whatsoever, you probably are missing the point.
A few additional assumptions, if unclear:
- Consider that no person in the city dies.
- The kids will not become parents themselves during the time horizon of the analysis.
- The marriages remain fixed.
Naive Intuition
When we consider a short time horizon, we can easily imagine large families that have many daughters and a single son, thus there must be more girls than boys. Additionally, at a longer time horizon, most families would be expected to have a boy and stopped having more kids. We could conclude then that the percentage of male children is small at the beginning and slowly increase over time, never exceeding \(50\%\).
Simulation
So, what exactly went wrong?
The number of large families is surprisingly small!
Analysis
The key word in the problem statement is expected. No real calculation is needed to see that at each time step an equal number of female and male babies are expected be born. Therefore, the proportion of male and female children is expected to remain at \(50\%\).
Any doubts?
Mathematical arguments must ultimately convince the reader. Let us consider the number of female children within each family as an independent random variable \(f_i\), where \(1 \leq i \leq 10^5\). By the problem statement, \(f_i\) follows a geometric distribution with success probabiliy \(p=0.5\). Thus, the probabiliy of having \(k\) girls before a boy is given by \(P(f_i = k) = (1-p)^k p\). The mean of this distribution is given by \(\frac{1-p}{p}\), which in our case is \(1\). In other words, in average each family will have one boy and one girl.
Finally, by linearity of expectation, we can observe that for the whole population the expected ratio of male to female children remains at \(50\%\).
Conclusion
It is very easy to have the wrong intuition about simple statistical concepts, even for a person with good working knowledge of statistics. Consider the case where one needs to examine evidence and make decisions for a complex model of reality, how likely are we to have an appropiate intution? It is really key to study simplified cases to build up our intuitive reasoning. Even small tweaks into seemingly simple models can create insanely complex behaviors (e.g. Rule 30).
One thing to notice is that most people tend fo focus on extreme behvior of each family, rather than the general trend of the population growth. Moreover, regardless the intention of each family to have boys (specified by the stopping rule), this only affects the size of one family, not the male ratio within the population.

Functions for handling internal flash memory.
The internal flash memory on the XMEGA devices consists of the application section, the application table section and the bootloader section. All these sections can store program code for the MCU, but if there is available space, they can be used for storing other persistent data.
Writing the flash memory can only be done one page at a time. It consists of loading the data to the internal page buffer and then running one of the write commands. If the page has not been erased before writing, the data will not be written correctly.
In order to be able to write to flash memory the programming commands need to be run from the boot section.

One of the biggest differences between today’s reality television and its 1973 antecedent is the genre’s status. Having outgrown PBS, it has inherited the rotten reputation that once attached to the medium itself. In an era of televised precocity—ambitious HBO dramas, cunningly self-aware sitcoms—reality shows still provide a fat target for anyone seeking symptoms or causes of American idiocy; the popularity of unscripted programming has had the unexpected effect of ennobling its scripted counterpart. The same people who brag about having seen every episode of “Friday Night Lights” will brag, too, that they have never laid eyes on “The Real Housewives of Atlanta.” Reality television is the television of television.
[...]
Having logged those thousand hours, Pozner can attest that reality shows have a tendency to blur together into a single orgy of joy and disappointment and recrimination. In her view, this is no coincidence: the shows are constructed to reinforce particular social norms, she argues, and she finds examples from across the reality spectrum.
From this New Yorker piece on reality TV. Its very interesting to think about the scripts of reality TV shows drawing from a pool populated by social norms. Usually art has a creator behind it, who has a purposeful intent in the way he/she is depicting life or a slice of life. I suppose in some ways if we all can draw from the same or similar pool of social norms, then it makes sense that a depiction of that on TV should be quite popular.


Notes on CS56 M16 E01
These are notes for the instructor to go over after the exam is returned to the students. These are various issues that the instructor and TAs found while grading the exams.
Question 1
Question 2
Question 3
Question 4
Question 5
Question 6
On question 6, the wording of the question said:
If an object is still not eligible for garbage collection when the last line of main is reached, write “never”. Your answer should be one of the line numbers that appears in comments in main (e.g.
/* 3 */
or/* 7 */
) or the word “never”.
As it turns out, this was perhaps not the best wording to use.
If we consider, for example, (b) Rover
, that object is still referred to
by d6
as the time that line /* 15 */
is reached.
Since d6
is in fact a local variable on the stack, when line 15 is reached,
d6
is no longer a live variable, and since this was the last live
reference to the Rover
object, the correct answer to (b) should be
15
.
Because of the way the question was worded, we accepted never
for
full credit. However, what I should have said was: if an object may
still be live when line 15 is reached, write “never”. That would
cover the case of objects still reachable from static data members
of classes, such as the dogOfTheWeek
reference.
That was my intention for the “never” answer, but my choice of words may have resulted in some misunderstanding. We resolve this matter in the student’s favor. (Thanks to Hiranya for raising the issue. )

GNSDK supports identification of both non-streaming and streaming music. Non-streaming music generally refers to music stored as a file or on a CD. Streaming music refers to music that is delivered in real-time as an end user listens. Listening to a song on the radio or playing a song from a media player are both examples of streaming music.
GNSDK allows you to identify non-streaming music using a CD TOC, information extracted from an audio file, or Gracenote identifiers.
GNSDK allows you to identify streaming music by generating fingerprints from a streaming audio source, which are then used to identify the music.

Lose Yourself In Music!
Music is an art form and cultural activity whose medium is sound organized in time. The common elements of music are pitch (which governs melody and harmony, rhythm and its associated concepts tempo, meter, and articulation, dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the color of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek mousike; art of the Muses.
In its most general form, the activities describing music as an art form or cultural activity include the creation of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres and it is music to my ears point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."
The creation, performance, significance, and even the definition of music vary according to culture and social context. Indeed, throughout history, some new forms or styles of music have been criticized as not being music, including Beethoven's Grosse Fuge string quartet in 1825, early jazz in the beginning of the 1900s and hardcore punk in the 1980s. There are many types of music, including popular music, traditional music, art music, music written for religious ceremonies and work songs such as chanteys. Music ranges from strictly organized compositions–such as Classical music symphonies from the 1700s and 1800s, through to spontaneously played improvisational music such as jazz, and avant-garde styles of chance-based contemporary music from the 20th and 21st centuries.
Music can be divided into genres (e.g., country music) and genres can be further divided into subgenres (e.g., country blues and pop country are two of the many country subgenres), although the dividing lines and relationships between music genres are often subtle, sometimes open to personal interpretation, and occasionally controversial. For example, it can be hard to draw the line between some early 1980s hard rock and heavy metal. Within the arts, music may be classified as a performing art, a fine art or as an auditory art. Music may be played or sung and heard live at a rock concert or orchestra performance, heard live as part of a dramatic work (a music theater show or opera), or it may be recorded and listened to on a radio, MP3 player, CD player, smartphone or as film score or TV show.
In many cultures, music is an important part of people's way of life, as it plays a key role in religious rituals, rite of passage ceremonies graduation and marriage, social activities (e.g., dancing) and cultural activities ranging from amateur karaoke singing to playing in an amateur funk band or singing in a community choir. People may make music as a hobby, like a teen playing cello in a youth orchestra, or work as a professional musician or singer. The music industry includes the individuals who create new songs and musical pieces (such as songwriters and composers), individuals who perform music (which include orchestra, jazz band and rock band musicians, singers and conductors), individuals who record music (music producers and sound engineers), individuals who organize concert tours, and individuals who sell recordings and sheet music and scores to customers.
Music is one of the most fundamental forms of human artistic expression. We have no way of knowing when humans started making music, as such origins are lost in the mists of prehistory, but humans have certainly been making music in one form or another for a very long time indeed. Whether it is simply chanting or drumming by one or two people or the collaboration of more than one hundred musicians in a full-sized orchestra, music is one of the most emotive and compelling forms of art.
There are far too many styles, genres, subgenres, and traditions of music to list here; such an inventory would go on for hundreds of pages. Instead, this lesson will focus on three basic categories for producing and thinking about music: Western art music, folk music, and popular music. Western Art Music
This category of music refers to the family of styles and genres that have developed out of the Western art music and classical tradition. This category of music is sometimes simply referred to as classical music but this term is somewhat misleading as the classical period in Western art music was a specific era that lasted from about 1730 to 1820 and does not really apply to periods before or after that time.
Western art music is characterized by compositional sophistication, virtuosity on the part of individual musicians, use of standardized musical notation, and association with the educated elites of Europe. Indeed, this last element is perhaps Western art music's most definitive feature. Western art music from the Middle Ages onward has positioned itself as the cerebral, culturally refined alternative to the folk and dance music of the common people. While individual composers may not have been members of the European aristocracy, with few exceptions they were funded by and making music for either the aristocracy or the church. Folk Music
Folk music is not a genre, but rather a process through which music is produced. It is not composed by any one individual; instead, it is produced by a community over a period of time. Typically, folk music is constantly changing with additions being made while other elements are eliminated. Folk music can be understood to be the traditional music of any particular ethnic group or community that is passed down through informal means from one generation to the next.
Unlike Western art music, folk music is typically not notated or written down, although sometimes it can be. It is most often shared orally and taught from teacher to student by ear and can include anything from a cappella English ballads, to complex African drum patterns used for religious purposes, to the rich folk music traditions of South Asia involving sitars, tablas, and vocals. The key factors in distinguishing folk music traditions from other methods of musical production are its traditional basis and communal composition. Popular Music
Like folk music, popular music is not a genre, but rather a process through which music is produced, distributed, and consumed. Popular music refers to any form of music that is mass produced or distributed, particularly if the music in question was written specifically for commercial purposes. Popular music is composed with the intention of profiting from that music's mass distribution, either through the record industry or through other means, such as for films, television, or online.
Rock music is perhaps the popular music genre par excellence, although genres like hip-hop, techno, and Bollywood soundtracks are also excellent examples. It can be argued that popular music did not really exist prior to the 19th century, when the recording and mass distribution of music first became possible.

Proxmox VE - open source virtualization management
Set up a small proxmox cluster to manage VMs
Up until now I have been managing my local VMs with KVM, Quemu and libvirt, using headless Ubuntu 20.04 LTS on the hosts as well as on the VMs, creating the VMs using scripts and cloud init files, and periodically updated the VMs and the hosts manually.
I have 3 decent physical machines (i7 with 16 cores and 64 GB memory) at my disposal and want to use them to run a local Kubernetes cluster. As I am still experimenting with Kubernetes, I want to be able to run multiple clusters on those machines and easily create and destroy them. For now, using VMs as nodes seems to make sense. At a later point I might scrap it all and go for a bare metal single cluster approach.
For now, it would be nice to make it easier to manage my VMs, and for that reason, I’ll do an experiment with Proxmox VE.
Preparation
The first step is to install Proxmox VE on each of the 3 machines.
After downloading the ISO image and the admin manual, it’s time to create a USB stick.
Following the instructions on my Mac, convert the .iso file to .img
hdiutil convert -format UDRW -o proxmox-ve_7.0-1.dmg proxmox-ve_7.0-1.iso
Then determine which disk it is:
diskutil list
And unmount it:
diskutil unmountDisk /dev/disk2
Finally, write the dmg file to the USB stick:
sudo dd if=proxmox-ve_7.0-1.dmg of=/dev/rdisk2 bs=1m
And this is where the fun starts :) with the following error:
dd: proxmox-ve_7.0-1.dmg: Operation not permitted
A bit of googling brought me to this post with a solution, giving ‘Full Disk Access’ to iTerm. It’s kind of hard to believe that I did not run into this before.

Once booted, the first step of the installation process is straight forward. For now, I selected xfs as file system, as it seems to be the best fit for my use case, and choose the biggest and fastest disk as starting point. I also configure each server with a fixed IP.
Once rebooted, a friendly message shows up requesting to use a web browser to configure the server. After having done so, the next step is to configure the repositories. Navigate to the host/Updates/Repositories, add the No Subscription repository and disable the enterprise repository:
As I had some spare SSDs available, I want to see if they can be used by VMs as well. For now, let’s create a logical volume group for them. Open the shell and list the available physical disks using:
lsblk -d
In my case, I have 4 additional disks: sda, sdb, sdc and sdd. So, let’s go ahead and create physical volumes for them:
pvcreate /dev/sda /dev/sdb /dev/sdc /dev/sdd
Then create a single volume group:
vgcreate vm-data /dev/sda /dev/sdb /dev/sdc /dev/sdd
And create a logical volume:
lvcreate -L 500G -T -n vm-data vm-data
Then go ahead and follow the same steps on the other two hosts.
Clustering the Proxmox servers
From one of the servers, navigate to Data Center/Cluster and chose to create a cluster. Give it a valid name, I chose vm-hosts for now. Once completed, click on Join Information and copy the join information.
Then, on the other servers, navigate to Data Center/Cluster chose to join a cluster. Enter the join information and the original host’s root password and wait for the process to complete. Once completed, all 3 hosts show up and can be managed from any of the instances:
Create a VM
Let’s finish up with creating a simple VM.
Download the latest Ubuntu release from https://ubuntu.com/download (or pick any other iso you want to use). Select a host, navigate to one of its storage options and go to ISO images. Upload the image so it is ready to be used:
Now create a VM on that host. The options should be pretty self-explanatory, have a look at the proxmox documentation for the details. I keep it simple for my first VM and use the default settings in most places. I decide to give it a 20GB hard drive, 2 cores and 4GB of memory. I’ll leave the VirtIO paravirtualized network selected for now and select to start it after it is created:
The VM is created and after a short wait, the Console can be used to go through the installation process.
Next Steps…
Plenty of ways to go from here. From using cloud init files to automate the installation process to trying out if terraform would also be an option.
As for me, the main reason to set this up was to prepare for some experiments running Kubernetes with Talos. Let’s see how that works out!

Behringer’s Wasp synth clone revealed… and you can pre-order it now
by Ben RogersonBehringer’s Wasp synth clone revealed… and you can pre-order it now
If Behringer was planning another drawn-out teaser campaign for its Wasp synth clone it can forget about it now, as US retailer Sweetwater has swatted that away by posting specs and images on its website.
This is a monophonic synth that promises the biting, buzzy sound that its name suggests. There are two digital oscillators, each with three variable waveshapes (pulse, ramp and enhanced mode) with pulse width modulation on Oscillator 1 and variable pitch control on Oscillator 2.
Next in line is an analogue VCF with high-pass, low-pass, notch and band-pass modes, along with sweepable resonance. Throw in an LFO (with six selectable waveforms and pitch and frequency mod controls) and two analogue envelope generators and you’re pretty much there.
Although it looks like this is an emulation of the Deluxe version of the Wasp (a later revision of the 1978 original), it doesn’t have that synth’s keyboard. Instead, it’s a Eurorack-compatible 80HP unit along the lines of Behringer’s K-2, Pro-1, Model D and Neutron synths.
You can also combine multiple synths for up to 16 voices of polyphony via the Poly Chain feature, while MIDI connectivity is via USB and standard 5-pin DIN (In and Thru).
If Sweetwater has it right, the Behringer Wasp will cost $299. It’s available for pre-order now, though we don’t yet know when it’ll ship.


module Clist: sig
.. end
Utilities for managing "concatenable lists" (clists). We often need to
concatenate sequences, and using lists for this purpose is expensive. This
module provides routines to manage such lists more efficiently. In this
model, we never do cons or append explicitly. Instead we maintain
the elements of the list in a special data structure. Routines are provided
to convert to/from ordinary lists, and carry out common list operations.
type 'a
clist =
| |
CList of 'a list |
| |
CConsL of 'a * 'a clist |
| |
CConsR of 'a clist * 'a |
| |
CSeq of 'a clist * 'a clist |
The clist datatype. A clist can be an ordinary list, or a clist preceded
or followed by an element, or two clists implicitly appended together
val toList : 'a clist -> 'a list
Convert a clist to an ordinary list
val fromList : 'a list -> 'a clist
Convert an ordinary list to a clist
val single : 'a -> 'a clist
Create a clist containing one element
val empty : 'a clist
The empty clist
val append : 'a clist -> 'a clist -> 'a clist
Append two clists
val checkBeforeAppend : 'a clist -> 'a clist -> bool
A useful check to assert before an append. It checks that the two lists
are not identically the same (Except if they are both empty)
val length : 'a clist -> int
Find the length of a clist
val map : ('a -> 'b) -> 'a clist -> 'b clist
Map a function over a clist. Returns another clist
val fold_left : ('a -> 'b -> 'a) -> 'a -> 'b clist -> 'a
A version of fold_left that works on clists
val iter : ('a -> unit) -> 'a clist -> unit
A version of iter that works on clists
val rev : ('a -> 'a) -> 'a clist -> 'a clist
Reverse a clist. The first function reverses an element.
val docCList : Pretty.doc -> ('a -> Pretty.doc) -> unit -> 'a clist -> Pretty.doc
A document for printing a clist (similar to docList
)


xbim Flex is a cloud-based service to host and manage BIM data using OpenBIM format and Open APIs.
It's a free for personal use, and designed to make it very simple to work with building data in open formats. You can upload a model in IFC format, and by using our simple REST APIs can interact with the data and visualise the the model in seconds.
To make things even easier we've provided some front-end libraries so you can bootstrap a new application in seconds. While you can just use our pre-generated Typescript libraries (both generic and for Angular) to access our services, we recommend using our Angular Flex Webkit library, which we're using in this demo.
Our own applications such as are built on exactly the same Webkit library client APIs so all those features are available to you, and obviously we'll be adding more features in future. If you've not seen already you can view a public demo here:
You (and your users / customers) retain ownership of your/their data, and the Flex access control systems ensure only people you authorise can access your data. For mode details see the Flex Terms of Service and Privacy Policy
This repo demonstrates some of the functionality of Flex. We'll be adding more samples soon to don't forget to
git pull
frequently!
Here's a quick overview of the Flex architecture. In this repo, we're building an application in the purple section at the top.
A key element of the Webkit solution is how it manages data using the 'Redux' state pattern. In a highly asynchonous application such as this, where there are many interactions with the Flex service via an API, the state management pattern simplifies the code required to track state changes. We employ this pattern using the NGXS library, and use it to undertake all interactions with our API. That includes:
To see how state is managed and how actions are trigger to change state we recommend installing the Redux Devtools extension in your chosen browser.
To see the demo in action, in the next section we'll look at authentication and getting your users signed in.
