Done With Week 7 of Course 3 at Tealeaf Academy
As I race towards the end of the last of Tealeaf’s courses (only 1 week after this!), I find myself learning more in each lesson than a few of the previous ones combined. The amount of learning is growing at an exponential rate!
Stuff We Learned
This week we covered all kinds of cool stuff. The first half of the week we covered building wrappers for connecting with APIs, fully integrating APIs into your testing, using the webmock and VCR gems to “record” the responses of API requests so only your first test actually hits the server. Learning about that led us to cover some advanced topics in testing and RSpec. Specifically, we covered test doubles, stubs, mocks, and testing JS using Selenium.
In the second half we covered going beyond the simple MVC architecture of Rails to accommodate more complex applications. This included things like extracting various parts of logic to decorators, policy objects, domain objects, and service objects. We then learned how to test this object composition using message expectation in RSpec.
First Half of The Week
So we started out the first half of the week by moving our all of the logic concerning interacting with the external Stripe API into an API wrapper (/app/models/stripe_wrapper.rb
). Moving that kind of logic into a wrapper is great because it allows you to remove unnecessary noise from your controllers, and it allows you to test the API interactions in one place.
Speaking of testing API interactions, we made use of the webmock and VCR gems to “record” the response coming back from Stripe’s servers the first time we hit them with the test. This is great because it significantly cuts down the time it takes to run subsequent tests. The first time I went to use VCR however, I was given an error saying that my YAML version was out of date. This was an easy fix be re-installing ruby using rbenv. This updated YAML for me.
We are using stripe.js to handle our payments, because it allows you to capture user’s credit card numbers without them ever touching your server. Because of this however, our feature tests need to be able to interact with JavaScript. We accomplished this by using the selenium-webdriver with capybara and the database_cleaner gem. Here again I ran into a bit of an issue. This time, the issue was really two issues.
First, capybara wasn’t able to open the email sent by my server and click the link in it. This is solved by manually setting the capybara and test port to be the same. So in my spec_helper.rb
file, I added the following at the very bottom:
Then in my config/test.rb
file I changed the line
to
The second issue I was having was with the database_cleaner gem. For one of my tests, it wasn’t cleaning the database correctly and was causing it to fail. To fix this I just needed to change the DatabaseCleaner.strategy
to :deletion
.
So, after moving our API interaction logic to a wrapper, we could test that thoroughly and be confident that any calls to it would function as they should. This allowed us to remove explicit calls to the wrapper from our controller tests and instead replace them with test doubles and stubs. Basically, this means that we “mocked” or faked the response of calling a method from the wrapper and forced it have the response we want.
For example, in our users_controller_spec, we test a user signing up for our service, which includes paying with a credit card. Instead of actually going through all the way of actually hitting a method in our Stripe wrapper and getting a response from it, we can stub it. All we really care about it is what our UsersController does when there is a successful charge. So, we can simulate the response of a successful charge without actually having to create a successful charge. Once again, this gives us the ability to test the logic of our wrapper in only one place without having to worry in other specs about how to get a successful response from it. If later down the road we were to change our API wrapper, we would only need to update the spec for it.
Testing like this is especially useful for large organizations because it allows individuals or teams to work on one part of the application without really having to worry about the logic of another part. It makes code a lot more reusable, changeable, and stable.
Second Half of The Week
In this part we covered some of the aspects of application design that go beyond just a simple MVC structure. While you can push logic from your controller down to your model to achieve a “skinny controller and fat model”, eventually your model might become a huge, bloated monster. That’s when it may be a good idea to start moving some of the logic into their own objects.
We covered decorators, policy objects, domain objects, and service objects.
Decorators are where you put the presentation logic. For example in our application we had a small conditional in our video show template. Basically it showed the average rating of the video if there were one, and displayed “N/A” if there weren’t any reviews for that video. We moved that logic into a decorator.
Policy Objects are a great place to put logic about users’ privileges and access. For example, our app only has the simple distinction of being an admin or not being an admin. So the admin?
method in the User model is good enough for us. However, in a more complex application this is where you could put the logic to determine what kind of access different users of different levels have.
Domain Objects are where you extract the “nouns” to. This is a good place to wrap up logic you have for interacting with an attribute of a model. For example, say you have a User model that has a credit attribute. In your application, you may have to reference and modify that credit attribute a lot. It doesn’t really make sense to make credits their own model extended from ActiveRecord with a database table. However, it would be nice to not have to call current_user.credit
all the time. This is what domain objects are for. You can create a Credit object that handles all the logic of accessing the user and manipulating the credit attribute.
Service Objects if domain objects are where you extract your nouns to, service objects are where you extract your “verbs” to. In our application, we have a somewhat complicated set of actions that occur when a user signs up. We were able to extract this process into a UserSignup object. This gives us a really clean, easy to read controller. It also gives us the ability to test the sign up logic in isolation.
It’s not always necessary, or even beneficial at all to move logic to any of these objects. If your logic is simple enough and not cluttering your controllers or models, it might help to keep it all in one place. However, if you’re dealing with a really complicated process in your controller, or a really bloated model, it makes sense to move that logic out.
After you start splitting your logic into smaller pieces, you can write very specific, focused specs that cover the permutations of that piece of logic. It is then no longer necessary, or useful to test that logic again in another spec. However, you do need to test that your different pieces are communicating with each other correctly. This is where message expectation comes in handy. This allows you to assert that, for example, a controller delegates a certain action to a service object. Once again, this allows you to test the logic of the service object and the controller isolated from each other.
Final Thoughts
This week was awesome because we covered a whole lot of advanced topics that I think are going to help me in my future projects and in landing a job doing something I love.
I only have one more week of class and then I am completely done! It has been a wonderful journey so far and I can’t wait to see what is in store for me next.


Procedures
Fire Drills
Seema conducts fire drills once a month. She will let you know in the morning if she will do a fire drill that day. In the case of a fire please:
- Have your students line up and go out the door single file.
- Please bring a first aid kit (which should be kept by the door) and your class roster (in iPad or binder form)
- Have all students go to your designated "fire spot": for Fulton this spot is the field behind the building, for the Hood Ave campuses this location is the Macadam Bar & Grill parking lot
- Keep your class grouped together once you reach the fire spot
- Make sure all children are present and accounted for and hold up your "all present" sign
- Wait for fire personnel to tell you it is safe to go back inside the building or wait for further instruction
Lock-Down
In the case of a lock-down go into your classroom or another space where you can close and all the doors and windows. Close the blinds and lock the doors if possible, stay away from the doors and windows. Keep children calm and quiet. Call 9-1-1 if police have not yet been notified. Wait for authorized personnel. More information.
Calling 9-1-1 or non-emergency
You should call 9-1-1 if:
- If a child falls off a structure and loses consciousness
- If a child has an allergic reaction even after you administer an epi-pen
- If a child is injured in such a way that they are losing a lot of blood from a major artery or vein
- If there is a fire
- If you see an individual or group with a weapon near the school
- If an individual exposes themselves to a student
- If a child goes missing during the school day
You should call the non-emergency number<PHONE_NUMBER>) if:
- You see suspicious but non-threatening behavior (i.e. someone walking down the street looking in all the car windows)
- If you want to dispose of something you feel could be evidence (like when Seema found the bag of porn outside of Hood Ave)
- To report a burglary that is complete and the suspects are gone (i.e. if the school was broken into overnight)
- If you are in a potentially criminal situation and feel uncomfortable or unsure of what to do, but don't think it is urgent or dangerous enough to call 9-1-1
Calling Parents
Of course you should call parents if their child is involced in any situation involving 9-1-1 or the non-emergency police number. However, there are some other times when you will need to call parents:
- If a student has a temperature over 98.6F (37C)
- If a student throws up
- If a student has a weeping or pink eye (pink eye)
- If a student is coughing a lot or is so sick they are unable to participate in activities
- If a child develops a rash
- If they are scratching their head a lot and you suspect lice.
- If they hit their head (see "Head Injuries" section)
You can find parent contact information in the FileMaker database. This database is loaded on all of the iPads. If for some reason this is not available there is a binder in the front office at all locations with the child authorization forms. Finally you can go directly into a student's file if neither of these options works. Be sure to leave a message on each number you call.  These are possible symptoms of highly contagious conditions that could spread throughout the class and possibly the school and CCD requires that they leave the campus immediately to reduce their exposure to other students. If a child's symptoms are severe enough and you do not reach either of the primary contacts continue on to emergency and non-emergency contacts.
Head Injuries
It is school policy to notify parents whenever a child hits their head. If it is obvious the child is fine it is sufficient to just leave a message if you do not reach the primary contact. I like to follow this script: "Hello, this is [insert your name] from L'Etoile French Immersion School. I am calling to let you know that [student] hit their head [describe accident], it is our policy to contact parents whenever there is a head injury. We applied ice and your child calmed down very quickly and appears to be fine now. If it is ok with you we can keep your child here and we will let you know if their condition changes." If a child is showing signs of a concussion call the primary, emergency and non-emergency contacts until you find someone who is able to pick the child up right away.
Here are the signs of a concussion:
- Balance problems
- Fatigue/sleepiness
- Vomitting
- Headache
- Difficulty remembering things
- Blurry vision
Biting
If a student bites another student please write incident reports for both children and send an email to the parent of the child who did the biting.
Incident Reports
If an accident occers that is not serious enough to call a parent but will leave a noticeable mark on the student (bruises, scrapes, cuts, etc) please follow first aid procedure and fill out an incident report. These repots can be found in each classroom and in the back of the AFCA binder.

FIFA 20 Team of the Week (TOTW) 13 predictions with Liverpool midfielder and Kylian Mbappe
Here are our predictions for the FIFA 20 Ultimate Team TOTW 13 lineup including players from Liverpool, Manchester United, Real Madrid, Barcelona and PSG.
by Nathan BlissAfter scoring, assisting and being named Man of the Match in Liverpool's 0-3 win over Bournemouth on Saturday, Reds midfielder Naby Keita has a great chance of being named in the FIFA 20 Ultimate Team TOTW 13 lineup, alongside the likes of Kylian Mbappe and Lionel Messi this week.
Mbappe scored one and assisted another in PSG's 3-1 win over Montpellier in Ligue 1, but could lose out on a TOTW place thanks to Neymar's performance, with the Brazilian scoring a wonderful free-kick and registering an assist in the same game, and you can't have two players from the same team in a TOTW squad.
From around the world, Lionel Messi, Jadon Sancho, Luis Suarez, Heung-min Son, Raphael Varane, Marcus Rashford and Timo Werner all have a good chance of being named in the FUT TOTW 13 lineup, after some incredible individual performances.
It's very hard to call this one.
This is just a FUT 20 TOTW prediction, so there is no guarantee that any players mentioned will be included.
The FUT20 TOTW line-up is picked on single performances only, so goals and assists are not added accumulatively within the TOTW period.

Disclaimer: this is an old blog post from a very old wordpress blog and may contain inacuracies. I reproduced it as is for sentimental reasons. I may revisit this theme later.
I have a difficulty to understand functional programming concepts that I can’t put to some very simple and natural use (natural for me, of course). I need to find the perfect simple example to implement to finally understand something. And I’m not a computer scientist, so things like parsers and compilers have very little appeal to me (probably because I don’t understand them…). I’m a physicist, so this drives me to look for physical problems that can be implemented in Haskell so I can understand some concepts.
Monad transformers still eludes me. But I think I finally got the perfect subject were I can understand them: stochastic processes! First some book keeping:
import Control.Monad.State
import Control.Monad
import Control.Monad.Rand
Now, stochastic processes have characteristics related to two different monads. In one hand, they are dynamical processes, and the way to implement dynamics in Haskell is with state monads. For example, if I want to iterate the logistic map:
$$x_{t+1} = \alpha x_t\left(1-x_t\right)$$
$$ teste = teste $$
I could do the following:
f :: Double -> Double
f x = 4*x*(1-x)
logistic :: State Double Double
logistic = do x0 <- get
let x1 = f x
put x1
return x1
runLogistic :: State Double [Double]
runLogistic n x0= evalState (replicateM n logistic) x0
Running this on ghci would give you, for example:
*Main> runLogistic 5 0.2
[0.6400000000000001,0.9215999999999999,0.28901376000000045, 0.8219392261226504,0.5854205387341]
So we can make the loose correspondence: dynamical system ↔ state monad.
On the other hand, stochastic processes are compositions of random variables, and this is done with the Rand monad (found in Control.Monad.Random
). As an example, the Box-Muller formula tells us that, if I have two inpendent random variables $x$ and $y$, distributed uniformly between in the \([0, 1]\) interval, then, the expression:
$$\sqrt{-2\log(x)}\cos(2\pi y)$$
will be normally distributed. We can write then:
boxmuller :: Double -> Double -> Double
boxmuller x y = sqrt(-2*log x)*cos(2*pi*y)
normal :: Rand StdGen Double -- normally distributed
normal = do x <- getRandom
y <- getRandom
return $ boxmuller x y
normals n = replicateM n normal -- n independent samples from normal
Running this function we get what we need:
*Main> (evalRand $ normals 5) (mkStdGen 0) =
[0.1600255836730147,0.1575360140445035,-1.595627933129274,
-0.18196791439834512,-1.082222285056746]
So what is a stochastic process? In very rough terms: is a dynamical system with random variables. So we need a way to make the Rand
monad to talk nicely with the State
monad. The way to do this is to use a monad transformer, in this case, the StateT
transformer. Monad transformers allows you to combine the functionalities of two different monads. In the case of the StateT
monads, they allow you to add a state to any other monad you want. In our case, we want to wrap the Rand
monad inside a StateT
transformer and work with things of type:
foo :: StateT s (Rand StdGen) r
This type represent a monad that can store a state with type s, like the state monad, and can generate random variables of type r, like the rand monad. In general we would have a type
foo2 ::(MonadTrans t, Monad m) => t m a
In this case, t = StateT s
and m = Rand StdGen
. The class MonadTrans
is defined in Control.Monad.Trans
, and provides the function:
lift :: (MonadTrans t, Monad m) => m a -> t m a
In this case, t
is itself a monad, and can be treated like one through the code. It works like this: inside a do expression you can use the lift
function to access the inner monad. Things called with lift will operate in the inner monad. Things called without lift
will operate in the outer monad.
So, suppose we want to simulate this very simple process:
$$x_{t+1} = x_t + \eta_t$$
where \(\eta_t\) is drawn from a normal distribution. We would do:
randomWalk :: StateT Double (Rand StdGen) Double
randomWalk = do eta <- lift normal
x <- get
let x' = x + eta
put x'
return x'
runWalk :: Int -> Double -> StdGen -> [Double]
runWalk n x0 gen = evalRand (replicateM n $ evalStateT randomWalk x0) gen
The evalStateT
function is just evalState adapted to run a StateT monad. Running this on ghci we get:
*Main> runWalk 5 0.0 gen
[0.1600255836730147,0.1575360140445035,-1.595627933129274,
-0.18196791439834512,-1.082222285056746]
This is what we can accomplish: we can easily operate simultaneously with functions that expect a state monad, like put and get, we can unwrap things with <-
from the inner Rand
monad by using lift
, and we can return things to the state monad. We could have any monad inside the StateT
transformer. For example, we could have another State
monad. Here is a fancy implementation of the Fibonacci sequence using a State
monad (that stores the last but one value in the sequence as its internal state) inside a StateT
transfomer (that stores the last value of the sequence):
fancyFib :: StateT Int (State Int) Int
fancyFib = do old <- lift get
new <- get
let new' = new + old
old' = new
lift $ put old'
put new'
return new
fancyFibs :: Int -> StateT Int (State Int) [Int]
fancyFibs n = replicateM n fancyFibs
And we can run this to get:
*Main> evalState (evalStateT (fancyFibs 10) 1) 0
[1,1,2,3,5,8,13,21,34,55]

Reports static code problems detected by analysers combined by Phalyfusion via Phalyfusion executable file
The inspection requires Phalyfusion to be properly installed and set up in the IDE under Settings/Preferences | Languages & Frameworks | PHP | Quality Tools | Phalyfusion.
It is recommended to install Phalyfusion as a Composer dependency.
Phalyfusion needs to be configured fully via phalyfusion.neon. Analysers used by Phalyfusion must be configured properly either.
This inspection will run Phalyfusion as ./phalyfusion analyse ANALYSED_FILE. So make sure that all analysers used by Phalyfusion configured properly to run analysis on separate files of your project.

hlStickyElement
Directives are nice and all, but sometimes you want some control over the inner workings a bit. Angular Sticky has been build in such a way so you can also initiate a sticky element from the code using a service.
Because you're making the sticky element with this service rendering is not longer automatically done. If you do want automatic rendering. Use the service "hlStickyElementCollection" along with this service.

Hong Kong Protests
by Associated Press1 / 14Police spray blue-dyed liquid from an armored vehicle during a confrontation with protestors at the Hong Kong Polytechnic University in Hong Kong, Sunday, Nov. 17, 2019. Police fired tear gas and water canons at protesters holding out at the Hong Kong Polytechnic University as overnight clashes resumed Sunday, and opposition lawmakers criticized the Chinese military for joining a cleanup to remove debris from streets.

HONG KONG (AP) — The Latest on the protests in Hong Kong (all times local):
8 a.m.
The president of a university in Hong Kong says that police have agreed to suspend their use of force after an all-night effort to flush out protesters occupying the campus.
Hong Kong Polytechnic University President Jin-Guang Teng said Monday that police would allow protesters to leave the campus, and that he would accompany them to the police station to ensure that their cases “will be fairly processed.”
He said in a recorded video message that he hopes protesters “will accept the proposed temporary suspension of force and leave the campus in a peaceful manner.”
It seems unlikely the protesters would accept the offer given that they would all likely be arrested.
___
6 a.m.
Hong Kong police have stormed into a university campus held by protesters after an all-night standoff.
Fiery explosions could be seen inside as riot officers entered before dawn Monday.
Police had fired repeated barrages of tear gas and water cannon at protesters outside the campus since before midnight.
Anti-government protesters had barricaded themselves inside Hong Kong Polytechnic University for days, fighting back with gasoline bombs and bows and arrows.
___
11:35 p.m.
Police have launched an operation to flush out protesters who have barricaded themselves inside a university in Hong Kong.
Tear gas barrages were fired late Sunday at protesters outside the campus after an ultimatum to come out expired.
Police have created a cordon around Hong Kong Polytechnic University to prevent protesters from escaping as they move in.
The protesters numbering about 200 people have assembled an arsenal of petrol bombs and bows and arrows to resist.
___
8:20 p.m.
Protesters have set fires on bridges leading to Hong Kong Polytechnic University as they try to keep police from advancing on their campus stronghold.
Orange flames extend the length of a footbridge over the roadway entrance to the Cross-Harbour Tunnel.
Police had shut down access to the area and massed earlier Sunday in an apparent attempt to surround protesters. Some retreated inside the campus while others remained outside to deter any advance.
Another fire was set on a bridge over the toll booths for the tunnel. Protesters have blocked access to the tunnel for days and set fires in the toll booths.
___
5:50 p.m.
Protesters have begun retreating inside Hong Kong Polytechnic University after a police tear gas volley from a new direction raised fears they would be caught in a trap outside.
The protesters had held ground all day Sunday near an intersection just outside the campus, as police fired tear gas and water cannons at them. Many wore rain ponchos and carried umbrellas.
Police moved in with tear gas from the other side, where protesters have shut down access to a major road tunnel under Hong Kong’s harbor for several days.
Protesters began streaming into the campus, which they have taken over and fortified against any police advance.
___
5:25 p.m.
Protesters have shut down a main street in Hong Kong’s Mongkok district, as police fire tear gas to try to disperse them.
Bricks have been strewn along part of Nathan Road, a wide thoroughfare lined with shops on the city’s Kowloon peninsula.
The Sunday afternoon traffic disruption appears to be a diversionary tactic as other protesters face down police tear gas and water cannons in a daylong standoff outside Hong Kong Polytechnic University.
Protesters have taken over the streets in Mongkok every night recently, but usually only after nightfall.
___
2:50 p.m.
A Hong Kong police officer has been struck in the lower leg by an arrow during a faceoff with protesters outside Hong Kong Polytechnic University.
Police said Sunday the arrow struck a media liaison officer. Photos posted on the police department Facebook page show the arrow sticking out of the officer’s leg.
Anti-government protesters fired arrows toward officers last week, but this is the first reported incident of anyone being hit.
___
2:05 p.m.
Police have unleashed water cannons on protesters in Hong Kong, drenching them repeatedly with blue-dyed and non-dyed water.
Other officers fired tear gas cannisters Sunday in a bid to drive out a determined group of protesters on the streets outside Hong Kong Polytechnic University.
The push by police came in an hourslong standoff that began in the morning.
Anti-government protesters who occupied several university campuses last week have largely retreated, but hard-liners have fortified themselves inside Polytechnic and refused to budge.
___
1:15 p.m.
Classes will remain suspended at Hong Kong schools on Monday because of continuing unrest in the city.
The Education Bureau says all classes from kindergarten through high school would be suspended because of safety concerns.
The bureau has canceled classes since Thursday, after coming under criticism for not doing so earlier.
It says schools are required to keep their premises open for students whose parents need to send them to school during the day.
Many students have joined anti-government protests, with children as young as 12 arrested by police. The Education Bureau says students should stay at home, not wander in the streets and must not participate in unlawful activities.
___
11 a.m.
Police have fired tear gas at protesters holding out at Hong Kong Polytechnic University as overnight clashes resumed in the morning.
A large group of people arrived Sunday to try to clean up a debris-strewn roadway. Riot police appeared after the cleaners were warned away by the protesters.
The police shot volleys of tear gas toward the protesters, who sheltered behind a wall of umbrellas across an entire street.
The skirmish came hours after intense overnight clashes in which the two sides exchanged tear gas and gasoline bombs. Many protesters retreated inside the Polytechnic campus.
Protesters have largely retreated from other major universities that were occupied for much of last week, but a contingent remains at Polytechnic.
Hong Kong’s anti-government protests have been raging for more than five months.

Creates a ChiSquared feature selector.
The selector supports different selection methods: `numTopFeatures`, `percentile`, `fpr`,
`fdr`, `fwe`.
* `numTopFeatures` chooses a fixed number of top features according to a chi-squared test.
* `percentile` is similar but chooses a fraction of all features
instead of a fixed number.
* `fpr` chooses all features whose p-values are below a threshold,
thus controlling the false positive rate of selection.
* `fdr` uses the `Benjamini-Hochberg procedure <https://en.wikipedia.org/wiki/
False_discovery_rate#Benjamini.E2.80.93Hochberg_procedure>`_
to choose all features whose false discovery rate is below a threshold.
* `fwe` chooses all features whose p-values are below a threshold. The threshold is scaled by
1/numFeatures, thus controlling the family-wise error rate of selection.
By default, the selection method is `numTopFeatures`, with the default number of top features
set to 50.

Ingredients
Sifting through hundreds of pages of ingredients is daunting and exhausting. In an effort to streamline some of the information we offer we want to highlight two categories of ingredients - the most common ingredients found in makeup and the most harmful ingredients found in makeup. We also provide links to other resources where you can find more information on these ingredients and others.

For this stage, we had to think of questions to ask interviewees centeralizing on the routes they take to make friends. After interviewing 3 students at Montclair State University, we then proceeded to find patterns in their responses to the questions we asked.
The goal was to find 5 websites and/or applications and select a 'Big Idea' from each that we thought would be useful to solving our solution. In the PDF, there are slides dedicated to explaining how the 'Big Idea' worked in the application/website as well as Pros & Cons of applying the 'Big Idea' to our application.
Conveying the Solution [PDF]We took our Persona #1, Mason Cooper, and developed a Context Scenerio. In the Context Scenerio, we explained a scenerio in which he would use the CollegeVibes application to make a friend. A storyboard is included as well for Persona #1.
Testing and Refining Our Solution [AXURE]We used the program Axure to create a Key Path Scenerio angled specifically to an actual student at Montclair State University. After interviewing the student beforehand, we were able to create a version of CollegeVibes tailored to her interests. Below is a video of the student using the application.
CollegeVibes Demo - Usablity Test [YouTube Video]In this video, a fellow teammate - Sarah Fathelbab - is using the Think Aloud Protocol. We test the main features of the CollegeVibes application and how the student interacted with the application as a whole.

MixUp is an app that helped me to discover different cultures, because i noticed that my circle of friends is kind of limited to people having the same background and cultures as me, and i think it's the case for most people. So, MixUp is the solution for diversity because it aims to widen & include different people in specific areas.
In my opinion, MixUp is the perfect solution to remove bias from people, and help including people of different backgrounds into other cultures
MixUp is a product that work for everyone and aims to include perspectives from all different backgrounds that vary by the differences already mentioned. So we can have more coherent communities.
As part of the classes I teach, I task my students with preparing a lot of presentations. To save time & reduce boredom, I occasionally have only a pick who presents the good work!

Test Data Setup with Fluent Builder Pattern
When writing tests I like to follow the arrange, act, assert pattern:
Arrange-Act-Assert: a pattern for arranging and formatting code in UnitTest methods. Each method should group these functional sections, separated by blank lines:
- Arrange all necessary preconditions and inputs.
- Act on the object or method under test.
- Assert that the expected results have occurred.
The first part of this pattern is explicit set-up of the test data in the test itself. I like this because you can see the connection between the test inputs and outputs, which makes the test easier to understand. I think once you've overcome the challenge of actually writing tests, the next big hurdle is making them comprehensible. I'm still working at this.
In the past I've often set-up test data like this:
[Test]
public void CrummySetup()
{
var request = new Request("GoodbyeCruleWorld")
{
Fields = new List<Field>()
{
new Field("XYZ", "Raleigh Chopper"),
new Field("ABC", "Ford Fiesta")
}
};
}
It's OK, but there are some problems. I want 3 things in my test data set-up:
- Terse - I want to be able to understand at a glance what's being set up.
- Refactorable - explicit use of the "new" operator, means that a change to the class's constructor causes a refactor of many test methods. On a recent project, where we started using dependency injection in anger, this point became a major ball breaker. Each addition of a new dependency caused a fantastically tedious rework of all the test methods.
- Hide irrelevance - I want to show a connection between input and output, so showing lots of parameters which don't matter makes the test hard to understand. Use of "new" exposes all of the parameters of the class, so the test gets cluttered up with irrelevance.
You want to hide the new operator for refactorability and to hide constructor irrelevance. The easiest way to do this is with a static factory method, which creates a fully valid default object. You want to the syntax to be terse, and emphasise the data which matters. A nice way to do this is with a fluent interface. A fluent interface allows method chaining, in the simplest case by returning the original object.
[Test]
public void QuailitySetup()
{
var request = RequestBuilder.Create("NewWorldOrder")
.WithField("XYZ", "Carbon Racing Bike")
.WithField("ABC", "Bugatti Veyron");
}
The syntax is terse, refactorable and hides irrelevance. Win, win, win. You implement it like this:
public static class RequestBuilder
{
public static Request Create(string name)
{
return new Request(name);
}
public static Request WithField(this Request request, string code, string name)
{
request.Fields.Add(new Field(code, name));
return request;
}
}
Fluent Builder
If you check out the builder pattern in the Gang of Four book, you may be hard pressed to see the connection with the code shown here. However if you check out the consequences of the builder pattern you see:
Builder Pattern
- Let's you vary the products internal representation.
- Isolates code for construction from representation.
- Gives you finer control over the construction process.
Which is exactly what the fluent builder does. It moves the construction code into it's own class, and allows you to vary what's made by calling different fluent extension methods.
My colleague Rich came up with this idea last week while we were working together. If you look around you can see we were not the first folks to have or name this idea. I guess that's what makes it a pattern. A full code listing follows:
using System.Collections.Generic;
using NUnit.Framework;
namespace FluentDataBuilderDemo
{
public class Field
{
public string Code { get; set; }
public string Name { get; set; }
public Field(string code, string name)
{
Code = code;
Name = name;
}
}
public class Request
{
public string Name { get; set; }
public List<Field> Fields { get; set; }
public Request(string name)
{
Name = name;
Fields = new List<Field>();
}
}
[TestFixture]
public class ShowDataSetup
{
[Test]
public void CrummySetup()
{
var request = new Request("GoodbyeCruleWorld")
{
Fields = new List<Field>()
{
new Field("XYZ", "Raleigh Chopper"),
new Field("ABC", "Ford Fiesta")
}
};
Assert.AreEqual(2, request.Fields.Count);
}
[Test]
public void QuailitySetup()
{
var request = RequestBuilder.Create("NewWorldOrder")
.WithField("XYZ", "Carbon Racing Bike")
.WithField("ABC", "Bugatti Veyron");
Assert.AreEqual(2, request.Fields.Count);
}
}
public static class RequestBuilder
{
public static Request Create(string name)
{
return new Request(name);
}
public static Request WithField(this Request request, string code, string name)
{
request.Fields.Add(new Field(code, name));
return request;
}
}
}


When useing the Virtual Breadboard you first select the tool which you wish to use. Then you click on the breadboard where you would like it to be placed. Each tool has different rules on how it is placed on the breadboard (Figure 3.1).
| Tool | How to use it |
|---|---|
| Chips | Click on the pin on the breadboard where the chips top left pin (usualy pin 14) is to be placed. Chips may only be placed to span the gap so you can only select the pins in the bottom row on the top half. |
| Seven Segment Display | Click on the pin on the breadboard where the seven segment displays pin 14 is to be placed. Seven segment displays may only be placed to span the gap so you can only select the pins in the bottom row on the top half |
| LED | Click on the pin on the breadboard that you want the positive end of the LED to be connected to then click the pin on the breadboard that you want the negetive end to be connected to. Since LEDs are diode this does matter. Electricity will flow only form positive to negitive. |
| Button | Click on the pin on the breadboard where you want one end of the button to be then click where you want the other to be. |
| Resistor | Click on the pin on the breadboard where you want one end of the button to be then click where you want the other to be. |
| Wire | Click on the pin on the breadboard where you want one end of the button to be then click where you want the other to be. |
| Tester | Click on the pin on the breadboard to see the voltage and other useful infomation. |
Using the proporties of each tool supplied in "The components" section wire up your breadboard.
Once every thing is hooked up the way you want it just hit the power dipswitch (beside the power LED and lable). This will execute your breadboard.


Your task is to assemble and modify the robot. The robot you assemble will work on building your Arduino skills, robotics and Bluetooth LE skills.

1. Assemble the BlueFruit robot.
2. Add a song to the robot.
3. Create at least one piece of armor or one weapon.
4. Take a picture of your robot and describe the rationale for the armor or weapon chosen for your robot.


Homework: webpack
This homework is intended to help you understand how to use webpack to split your front-end code into modules. webpack will bundle the dependencies into a set of files that you can distribute with your application.
Organizing your front-end code
webpack lets you install Javascript dependencies using node.js, e.g.
npm install --save react
. In your Javascript code, you can then use
require
to load the dependencies, just like in node.
You can see how I use webpack in this listomatic
repository.
To get started, organize your code into the following directory structure:
project
server.js // your server
node_modules
models // models for your node server
app // your front-end code
components // React components
css // custom CSS
You can put all your React components into app/components
.
Next, you need to install code you'll use for your front end:
npm install --save react react-dom react-router jquery
Then you can modify your main JS file, app/components/main.js
to use the following:
var React = require("react");
var ReactDOM = require("react-dom");
var ReactRouter = require("react-router");
require("../../node_modules/bootstrap/dist/css/bootstrap.min.css");
require("../css/app.css");
The second-to-last line should point to the bootstrap CSS you installed, which should be in your node_modules directory. The last line should point to your custom CSS file.
If you need to use jQuery, you can use:
var $ = require("jquery");
In any of your components.
Configuring webpack
Install webpack and some of the loaders we'll use to bundle JavaScript:
npm install --save-dev webpack file-loader babel-core babel-loader babel-preset-react
The webpack configuration is stored in a file called webpack.config.js
stored in the top level
of your project. Create this file and put the following inside:
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var CommonsChunkPlugin = require("webpack/lib/optimize/CommonsChunkPlugin");
module.exports = {
context: __dirname + "/app",
entry: {
javascript: "./components/main.js",
html: "./index.html",
vendor: ["jquery","react","react-router"],
},
output: {
filename: "js/app.js",
path: __dirname + "/public",
},
plugins: [
new ExtractTextPlugin("./css/styles.css"),
new CommonsChunkPlugin("vendor", "./js/vendor.js", Infinity),
],
devtool: 'source-map',
module: {
loaders: [
// loader for React JSX
{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel",
query: {
presets: ['react']
}
},
// loader for HTML
{
test: /\.html$/,
loader: "file?name=[name].[ext]",
},
// loaders for Bootstrap CSS
{ test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader","css-loader?sourceMap") },
{ test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file?name=assets/[name].[ext]" },
{ test: /\.(woff|woff2)$/, loader:"url?name=assets/[name].[ext]&prefix=font/&limit=5000" },
{ test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "url?name=assets/[name].[ext]&limit=10000&mimetype=application/octet-stream" },
{ test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: "url?name=assets/[name].[ext]&limit=10000&mimetype=image/svg+xml" }
],
},
}
This will bundle your JavaScript into public/js/app.js
, the JQuery
and React code into public/js/vendor.js
, and both the Bootstrap CSS
and your custom CSS into public/css/style.css
.
Your app needs to link to these files, so ensure app/index.html
looks
something like this:
<!DOCTYPE html>

<meta charset="utf-8">
<title>Listomatic</title>
<link href='http://fonts.googleapis.com/css?family=Romanesco' rel='stylesheet' type='text/css'>
<link rel="stylesheet" href="css/styles.css" />

In addition, your server should treat the files in public
as static files,
so your setup for Express should contain:
app.use(express.static('public'));
You can now run:
webpack
and this should produce all the files you need for your front-end in
the public
directory. You can alternatively run:
webpack --progress --colors -d --watch
This will cause webpack to stay active and reproduce the bundles any time you change your code. The "-d" option will produce source maps so that your code is easier to debug.
Understanding webpack
I'll walk through the webpack configuration a few lines at a time so you can understand what it is doing.
context: __dirname + "/app",
Indicates where you will store your front-end code, in this case in
the `app` subdirectory.
entry: {
javascript: "./components/main.js",
html: "./index.html",
vendor: ["jquery","react","react-router"],
},
Declares the entry points for webpack. It will scan the `javascript` entry to find any
dependencies. For example, my main.js file includes:
var App = require("./app.js");
var Home = require("./home.js");
var List = require("./list.js");
var Login = require("./login.js");
var Register = require("./register.js");
webpack will start at `main.js`, then follow all the files that it requires, recursively,
and compile them into one bundle. Likewise, `index.html` is an entry point; we'll configure
webpack to copy this file to `public`. The vendor entry points will be compiled into
a separate bundle, so that code from third-parties is separated from your app code.
output: {
filename: "js/app.js",
path: __dirname + "/public",
},
Determines where the bundles will be created. The main JavaScript bundle will be
placed in `public/js/app.js`. Notice that is the path we used in `index.html`.
plugins: [
new ExtractTextPlugin("./css/styles.css"),
new CommonsChunkPlugin("vendor", "./js/vendor.js"),
],
Loads several plugins. ExtractTextPlugin will take CSS out of your JavaScript
bundle and put them into a separate file, in public/css/styles.css
. CommonsChunkPlugin
creates a separate bundle for the vendor files in public/js/vendor.js
. Notice again
this is the path we used in index.html
.
// loader for React JSX
{
test: /.js$/,
exclude: /node_modules/,
loader: "babel",
query: {
presets: ['react']
}
},
Loaders are used to collect your code into bundles. This loader will run
for any files that end in .js
and use babel to compile your JavaScript
code. By setting the react
preset, babel will convert JSX to plain
JavaScript. Note that you could also set this up to use ES6.
// loader for HTML
{
test: /.html$/,
loader: "file?name=[name].[ext]",
},
This loader runs for any files that end in .html
and copies them
using the file loader to the public
directory, keeping their name
and extension unmodified.
// loaders for Bootstrap CSS
{ test: /.css$/, loader: ExtractTextPlugin.extract("style-loader","css-loader?sourceMap") },
{ test: /.eot(\?v=\d+.\d+.\d+)?$/, loader: "file?name=assets/[name].[ext]" },
{ test: /.(woff|woff2)$/, loader:"url?name=assets/[name].[ext]&prefix=font/&limit=5000" },
{ test: /.ttf(\?v=\d+.\d+.\d+)?$/, loader: "url?name=assets/[name].[ext]&limit=10000&mimetype=application/octet-stream" },
{ test: /.svg(\?v=\d+.\d+.\d+)?$/, loader: "url?name=assets/[name].[ext]&limit=10000&mimetype=image/svg+xml" }
These loaders are used for Bootstrap CSS. The first one runs for any
files ending in .css
and uses style loader to compile all the CSS
into a bundle. The ExtractTextPlugin will save this in a separate
file, rather than including it in the main JavaScript bundle. The
second one finds .eot
files, which are embedded fonts that Bootstrap
uses. These are copied with the file loader into the assets
directory. The third one finds .woff
files, which are also fonts,
and these are referenced with URLs in the Bootstrap source. These are
loaded with the URL loader, which returns a URL for the CSS to
reference. Similar loaders are used for the .ttf
and .svg
files
that Bootstrap references.

Nokia N-Gage
What a deal! For $CDN250 you get an unlocked, international phone, with Bluetooth, a colour screen, oh and plays games, oh and plays .WAV as a ringer! Oh, and it runs Java Midlets...
The N-Gage. With no sidetalkin'!. And I can switch back to my small phone thanks to SIM cards.
I'm convinced they are selling this as a loss-leader to their games, which is kind of silly considering that I downloaded Doom for it for free last night. Plus the Midlets you can get. One of the criticisms as a gaming platform is that the screen is portrait, not landscape. Frankly the phone is extremely useful without buying any games. (if a bit large, although maybe I'm biased). I've wanted to write code for something I carry with me since I went to JavaOne uh, in 1999 when they handed out Palm V's with early J2ME implentations.
(Christ, I've been doing Java for over 5 years now) (Crap, 7).

In the Meiji era of Japan, a doctor named Yukio is a doctor who has worked as a medic officer during the war, gaining fame in the process. He comes from a prestige family and is happily married. The life he leads seems perfect, but is shattered when his family members died under mysterious circumstances. Soon it is revealed that it is but Yukios twin brother, who was abandoned at birth due to a birthmark, is behind all the murders and he is now coming back to reclaim whats his, especially Yukios wife, who was once his lover
The film is a refreshing depart from Shinya Tsukamotos previous works, whose works previously included the very mechanical Tetsuo and its sequel, and also the very violent Tokyo Fist. All previous films he made were filled with jarring images and an almost incomprehensible plot, but Gemini is different. Gemini is made with the purpose of straight story telling. Despite this, Gemini still flashes the old Tsukamoto, with the opening showing a decomposed cat eaten but vultures and a scene with a nail is driven into a guys neck, sprouting blood.
Gemini also deals with duality. This can be seen right at the start of the film, where a contrast between the rich and the poor. He is born with a silver spoon in his mouth, and he despises the slum people. At one scene Yukio has to save between a poor woman is pleading for her child and the injury of the mayor, he chose the rich, and forced the old woman out. In the starkest contrast, however, is when his twin brother, who was abandoned when birth and forced to live within the slums, exchanged identity with Yukio by imprisoning him in a deep well and forcing him to eat on scraps of food. In this scene, we really see the reversed life on each other as a psychological game is played out, forcing him to reconsider the sides of the rich and the poor. As the end scene shows, after he kills and knows the truth of his twin brother, he walks into the slums, presumably to cure the poor people he once loathed. At a minor turn of duality also sees Yukios wife, whose lover was Yukios twin brother, has chosen to forsake a life of poorness and lives with Yukio, whom she has initially mistaken for the other guy. As I said to end this review, I would say Gemini is a compelling, albeit a little conservative directing from Tsukamoto, film, and I would highly recommend it.
(In Japanese With English subtitles)
Note: Gemini was shown on 9th April 2000 at the 13th Singapore International Film Festival and will be scheduled released for commercial release in Singapore on a later date.

1959–1989 Modernization and the Expansion of Scientific and Clinical Training
- To develop interdisciplinary clinical research with close ties to the basic sciences
- To consolidate and expand social and behavioral sciences
- To develop shared facilities involving the application of large instruments for structural biology groups
- To consider the possibility of creating advanced undergraduate programs in the health sciences
- To promote interactions with biotechnology and other relevant health-related disciplines in the industrial sector
- To develop programs to conquer AIDS and other diseases caused by retroviruses
The future space requirements for the campus were identified as requiring action along the following lines:
- To develop Laurel Heights as a vital academic center
- To acquire 50-100 acres to develop as a major campus site to preserve options for the future
- To acquire additional clinical facilities to free up clinical space immediately with no net increase of beds in the community
- To maximize utilization of Parnassus Heights space resources by scrutinizing existing space use and programs, renovate, and build new research space
A number of these goals have been met over the past twenty years. As the campus continues to grow—developing into new spaces at Mission Bay, integrating teaching in the Social and Behavioral Sciences and Medical Humanities within the core curricula and graduate instruction, promoting bioentrepreneurship and biotechnological advancement, and continuing to receive outstanding support for research in all areas of the health sciences—UCSF will have exceeded these goals and will be moving forward to reach its new mission: “advancing health worldwide.” A summary of some of the achievements and innovations post-1989 is provided in the final section of this history.
