What is Rails?
As with most topics related to programming, you must first understand one subject before you can understand another, and Rails is no different! Before we begin breaking down the uses of Rails and why it is so popular, let's take a look at GitHub's simple definition of the Rails framework:
If you're scratching your head, you're not alone. Rails cannot simply be understood by reading a simple definition, so let's dig in further!
------------------------
Getting to Know Ruby
Whenever you first meet someone, a popular first question to ask of that person is, "Where are you from?" To understand someone's (something's) origin is to better understand that person/thing itself. With that, Rails is a framework that is written in the Ruby programming language. Just in case you're unfamiliar with Ruby, it is an object-oriented, general-purpose programming language. Created over 20 years ago by Yukihiro Matsumoto, Ruby's popularity has grown immensely and is now one of the top 10 programming languages out there with regard to web programming. It is a dynamic language, popular because it can accomplish tasks using less code as compared to its programming cousins (Java, C++, etc.), and it can be learned more quickly than other languages as well.
Enter: Rails
So where does Ruby tie in with all of this? According to the RailsApp Project, Rails is a "software library that extends the Ruby programming language", or "software code that is added to the Ruby programming language" (hence the often used phrase "Ruby on Rails"). With Ruby's already existent awesomeness, using Rails to "extend" its greatness opens many doors with regard to our ability to build equally awesome websites! Just think of Ruby on Rails as Ruby on Steroids!
As I stated above, Ruby on Rails is used in the development of web applications. How does a framework benefit a developer as they're creating a new app? I'm a big fan of analogies, so let's use a slightly crude one to orchestrate the benefit of Rails. Imagine you are wanting to build a new deck on the side of your house. Before getting started, you'd need to draw up plans, purchase and organize your tools, and hire some good help (or borrow a brother-in-law) to help with the heavy lifting. Wouldn't it be great if you could have all of those steps done FOR YOU? That's what Rails accomplishes for a web developer. It helps organize your development tools (Ruby, JavaScript, HTML, CSS), gives you a loose framework to start with, and also helps you out with some of the heavy lifting along the way!
More technically speaking, it is "opinionated" software that encourages the developer to abide by certain suggestions and conventions contained within the Rails API (Application Programming Interface). This API can be viewed as a rulebook which standardizes the use of Rails. This standardization allows for better collaboration between developers, and paves the way for more focused resources for maintaining and improving the framework itself.
------------------------
The MVC Pattern
Let's take another look at the Rails description I gave you earlier:
The Model - View - WHO? To truly understand Rails, you'll need to also understand (recurring theme here, right?) the Model-View-Controller (MVC) pattern. MVC essentialls splits up your application intro three sections, or "layers", giving each individual sections it's own specific responsibility.
The model is essentially the central hub for all of the application's data and rules.
The view refers to any form of output to the user.
The controller is responsible for accepting input from the user and converting into commands for the model/view.
Based on the graphic below, you can see that these three components interact with one another as the application is being used, and allow the app to change with the user's direction/input. As you can see, this pattern is critical to the operation of the application, and explains why so many frameworks (like Rails) are geared towards MVC.
------------------------
A Parting Thought...
As you might have guessed, we've only scratched the surface when it comes to Ruby on Rails, but much of the knowledge that remains (as with most programming concepts) is best acquired through hands-on-practice. At this point, you at least have an understanding of "WHAT" and "WHY" Rails is, which only leaves the "HOW". So do some googling, a little bit of downloading, and a lot of programming so that you can add Rails to your resume with confidence!

`Deep Blue Sea' – Sharkfest Provides Moderate Bite by Homer Yen (c) 1999
DBS is a film that follows a formulaic storytelling mechanism that is as familiar to us as the smell of buttered popcorn. And if you've ever seen any of the `Alien' movies, then in many ways, you've already seen this film. The similarities between these films are as abundant as the gory shark attacks that are peppered throughout this film. In `Alien', the setting is a remote research station somewhere in space. Here, the setting is a research station somewhere in the Pacific Ocean. In `Alien' a band of humans must survive to escape an infestation of oozing, flesh-eating creatures. Here, a band of humans must survive to escape several very, very large sharks on the loose. But these are no ordinary sharks. These predators are 25 feet long, and their brains have been altered in a way as to make them amazingly intelligent, agile, and menacing.
The research station is headed by Dr. Susan McAlester (Saffron Burrows), a passionate scientist on the verge of a discovery that could change the face of medicine. As humans age, brain activity slows down considerably. As a result many suffer greatly from degenerative diseases, such as Alzheimer's. Yet sharks, for some reason, never suffer from these effects. Their brains remain fully functional throughout their life span. Her project is to find a way to extract the protein within the shark's brain responsible for this effect so that humans can take advantage of these benefits too – sort of a super gingko biloba. But she faces some overwhelming obstacles. Funding has been cut which forces her to take shortcuts and to overlook safety precautions. Meanwhile, to extract enough protein, the sharks' brains have been genetically altered. The side effect is that it makes them more ferocious and smarter. And did I mention that these beasts are 25 feet long? It's a recipe for disaster, and when the sharks eventually grow smart enough to fight back, the woeful few crew members on this isolated research station will become nothing more than feeder fish.
I think that when looking at a movie such as this, there are two components that will determine whether something like this can be recommended or not. One is whether we like the hapless souls fighting to stay alive. And for the most part, I liked the quirky cast of characters, especially the macho shark wrangler (Thomas Jane) and a delightful bible-quoting cook (LL Cool J). The shark wrangler is well-suited to stay alive, but his crazy heroics may get him killed. Meanwhile, when a shark enters the cook's partially flooded kitchen, he tries to hide in his own oven. But the shark is smart enough to set the oven to 400 degrees. Perhaps, this shark prefers his dinner cooked. To be sure, many will meet an untimely and unexpected horrible end. But these are two characters that I cared for and wanted to see survive. The other component, of course, is the action sequences. And, for the most part, they are all well done. They involve the familiar scenes where fierce creatures are chasing after humans through narrow passageways while the whole compound around them is slowly about to self-destruct. Meanwhile, the characters all do their best to escape from the jaws of death, do what they can to improvise their way out of seemingly hopeless situations, and work together to make it to freedom.

PhantomJS is a headless WebKit. FuncUnit integrates with Phantom to run tests from the commandline. This has large performance benefits, enough that it makes it much more feasible to integrate FuncUnit tests into your build process without significantly slowing it down.
Before you can use PhantomJS, you have to install it. The other automation tools come prepackaged in JMVC, but Phantom is too large of a download.
On Mac
sudo ln -s /Applications/phantomjs-1.3.0/bin/phantomjs /usr/local/bin/
Note: Not all systems will have /usr/local/bin/. Some systems will have: /usr/bin/, /bin/, or usr/X11/bin instead.
On Windows
To run any test via PhantomJS, use funcunit/run
./js funcunit/run phantomjs path/to/funcunit.html
If you notice a broken test, debugging it in Phantom is not the place to start. Open the test in browser, and verify the same test breaks there. If so, debug the test in browser.
If you notice the more rare event that a test breaks in Phantom but works in browser, you can use console.log
to debug it. In funcunit/commandline/phantomjs.js
, uncomment the print: true option. Add console.logs
to your code and debug.
One thing to be aware of is that phantomjs tests run within an iframe in the funcunit.html page. This is different from the normal behavior of opening the application page using window.open. Phantom doesn't support window.open, so a frame is used instead. This can occassionally cause problems if your application assumes it is running within window.top.

This post describes the steps to test a Camel K integration with YAKS both locally and on the Kubernetes platform.
What is YAKS?
YAKS is an Open Source test automation platform that leverages Behavior Driven Development concepts for running tests locally and on Cloud infrastructure (e.g. Kubernetes or OpenShift). This means that the testing tool is able to run your tests both as local tests and natively on Kubernetes. The framework is specifically designed to verify Serverless and Microservice applications and aims for integration testing with the application under test up and running in a production-like environment. A typical YAKS test uses the very same infrastructure as the application under test and exchanges data/events over different messaging transports (e.g. Http REST, Knative eventing, Kafka, JMS and many more).
As YAKS itself is written in Java the runtime uses a Java virtual machine with build tools such as Maven and integrates with well known Java testing frameworks such as JUnit, Cucumber and Citrus to run the tests.
Understanding the Camel K example
First of all here is a small sample Camel K integration that we would like to test in the following. The integration exposes a Http service to the user. The service accepts client Http POST requests that add fruit model objects. The Camel K route applies content based routing to store the fruits in different AWS S3 buckets.
In the test scenario YAKS is going to invoke the Camel K service and verify that the message content has been sent to the right AWS S3 bucket.
Here is a sample fruit model object that is subject to be stored in AWS S3:
{
"id": 1000,
"name": "Pineapple",
"category":{
"id": "1",
"name":"tropical"
},
"nutrition":{
"calories": 50,
"sugar": 9
},
"status": "AVAILABLE",
"price": 1.59,
"tags": ["sweet"]
}
Here is the Camel K integration route:
from('platform-http:/fruits')
.log('received fruit ${body}')
.unmarshal().json()
.removeHeaders("*")
.setHeader("CamelAwsS3Key", constant("fruit.json"))
.choice()
.when().simple('${body[nutrition][sugar]} <= 5')
.setHeader("CamelAwsS3BucketName", constant("low-sugar"))
.when().simple('${body[nutrition][sugar]} > 5 && ${body[nutrition][sugar]} <= 10')
.setHeader("CamelAwsS3BucketName", constant("medium-sugar"))
.otherwise()
.setHeader("CamelAwsS3BucketName", constant("high-sugar"))
.end()
.marshal().json()
.log('sending ${body}')
.to("aws2-s3://noop?$parameters")
The route uses content based routing EAP based on the nutrition sugar rating of a given fruit in order to send the fruits to different AWS S3 buckets (low-sugar, medium-sugar, high-sugar).
In the following the test case for this integration needs to invoke the exposed service with different fruits and verify its outcome on AWS S3.
How to test locally with YAKS
In the beginning let’s just write the test and run it locally. For now, we do not care how to deploy the application under test in the Cloud infrastructure as everything is running on the local machine using JBang.
JBang is a fantastic way to just start coding and running Java code and also Camel K integrations.
YAKS as a framework brings a set of ready-to-use domain specific languages (XML, YAML, Groovy, BDD Cucumber steps) for writing tests in order to verify your deployed services.
This post uses the Behavior Driven Development integration via Cucumber. So the YAKS test is a single feature file that uses BDD Gherkin syntax like this:
Feature: Camel K Fruit Store
Background:
Given URL: http://localhost:8080
Scenario: Create infrastructure
# Start AWS S3 container
Given Enable service S3
Given start LocalStack container
# Create Camel K integration
Given Camel K integration property file aws-s3-credentials.properties
When load Camel K integration fruit-service.groovy
Then Camel K integration fruit-service should print Started route1 (platform-http:///fruits)
Scenario: Verify fruit service
# Invoke Camel K service
Given HTTP request body: yaks:readFile('pineapple.json')
And HTTP request header Content-Type="application/json"
When send POST /fruits
Then receive HTTP 200 OK
# Verify uploaded S3 file
Given New global Camel context
Given load to Camel registry amazonS3Client.groovy
Given Camel exchange message header CamelAwsS3Key="fruit.json"
Given receive Camel exchange from("aws2-s3://medium-sugar?amazonS3Client=#amazonS3Client&deleteAfterRead=true") with body: yaks:readFile('pineapple.json')
Let’s walk through the test step by step. First of all the feature file uses the usual Given-When-Then BDD syntax to give context, describe the actions and verify the outcome. Each step calls a specific YAKS action that is provided out of the box by the framework. The user is able to choose from a huge set of steps that automatically perform actions like sending/receiving Http requests/responses, starting Testcontainers, running Camel routes, connecting to a database, publishing events on Kafka or Knative brokers and many more.
In the first scenario the test automatically prepares some required infrastructure.
The YAKS test starts a Localstack Testcontainer to have an AWS S3 test instance running (Given start LocalStack container
).
Then the test loads and starts the Camel K integration under test (When load Camel K integration fruit-service.groovy
) and waits for it to properly start.
In local testing this step starts the Camel K integration using JBang.
Later the post will also run the test in a Kubernetes environment.
Now the infrastructure is up and running and the test is able to load the fruit model object as Http request body
(Given HTTP request body: yaks:readFile('pineapple.json')
) and invoke the Camel K service (When send POST /fruits
).
The test waits for the Http response and verifies its 200 OK status.
In the last step the test verifies that the fruit object has been added to the right AWS S3 bucket (medium-sugar).
As YAKS itself is not able to connect to AWS S3 the test uses Apache Camel for this step.
The test creates a Camel context, loads a AWS client and connects to AWS S3 with a temporary Camel route
(Given receive Camel exchange from("aws2-s3://medium-sugar?amazonS3Client=#amazonS3Client&deleteAfterRead=true")
).
With this Apache Camel integration YAKS is able to use the complete 300+ Camel components for sending and receiving messages
to various messaging transports. The Camel exchange body should be the same fruit model object (yaks:readFile('pineapple.json'
)
as posted in the initial Http request.
YAKS uses the powerful message payload validation capabilities provided by Citrus for this message content verification. The validation is able to compare message contents of type XML, Json, plaintext and many more.
This completes the test case. You can now run this test with Cucumber and JUnit for instance. The easiest way though to directly run tests with YAKS is to use the YAKS command line client. You do not need to set up a whole project with Maven dependencies and so on. Just write the test file and run with:
```shell script $ yaks run fruit-service.feature –local
You should see some log output like this:

# Running YAKS in the Cloud
YAKS is able to run tests both locally and as part of a Kubernetes cluster.
When running tests on Cloud infrastructure YAKS leverages the Operator SDK and provides a specific operator to manage the
test case resources on the cluster.
Each time you declare a test in the form of a [custom resource](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/)
the YAKS operator automatically takes care of preparing the proper runtime in order to execute the test as a Kubernetes Pod.
Why would you want to run tests as Cloud-native resources on the Kubernetes platform? Kubernetes has become a standard target
platform for Serverless and Microservices architectures.
Developing the services is different in many aspects compared to what we have done for decades.
Writing a Serverless or Microservices application for instance with Camel K is very declarative.
As a developer you just write the Camel route and run it as an integration via the Camel K operator directly on the cluster.
The declarative approach as well as the nature of Serverless applications make us rely on a given runtime infrastructure,
and it is essential to verify the applications also on that infrastructure. So it is only natural to also move the verifying
tests into this very same Cloud infrastructure.
This is why YAKS also brings your tests to the Cloud infrastructure for integration and end-to-end testing.
So here is how it works. You are able to run the very same YAKS test that has been run locally also as a Pod in Kubernetes.
YAKS provides a Kubernetes operator and a set of CRDs (custom resources) that we need to install on the cluster.
The best way to install YAKS is to use the [OperatorHub](https://operatorhub.io/operator/yaks) or the yaks CLI tools that
you can download from the [YAKS GitHub release pages](https://github.com/citrusframework/yaks/releases).
With the yaks-client binary simply run this install command:
```shell script
$ yaks install
This command prepares your Kubernetes cluster for running tests with YAKS. It will take care of installing the YAKS custom resource definitions, setting up role permissions and creating the YAKS operator in a global operator namespace.
Important: You need to be a cluster admin to install custom resource definitions. The operation needs to be done only once for the entire cluster.
Now that the YAKS operator is up and running you can run the very same test from local testing also on the Cloud infrastructure.
The only thing that needs to be done is to adjust the Http endpoint URL of the Camel K integration from http://localhost:8080
to http://fruit-service.${YAKS_NAMESPACE
}
```shell script $ yaks run fruit-service.feature
Please notice that we have just skipped the `--local` CLI option.
Instead of using local JBang tooling to run the test locally now the YAKS CLI connects to the Kubernetes cluster in order
to create the test as a custom resource.
From there the YAKS operator takes over preparing the test runtime and running the test as a Pod.
But wait! The test did prepare some infrastructure, in particular the Camel K integration and the AWS S3 Localstack Testcontainer instance.
How does that work inside Kubernetes? YAKS completely takes care of it.
The Camel K integration is run with the Camel K operator running on the same Kubernetes cluster.
And the Testcontainer AWS S3 instance is automatically run as a Pod in Kubernetes.
Even connection settings are handled automatically. It just works!
You will see some similar test log output when running the test remotely and the test performs its actions and its validation
exactly the same as locally.
You can also review the test Pod outcome with:
```shell script
$ yaks ls
This is an example output you should get:
NAME PHASE TOTAL PASSED FAILED SKIPPED ERRORS
fruit-service Passed 3 3 0 0 0
Demo
The whole demo code is available on this GitHub repository. It also shows how to integrate the tests in a GitHub CI actions workflow, so you can run the tests automatically with every code change.
Conclusion
This blog post showed how you can test Camel K integrations locally and in a Cloud infrastructure with YAKS. YAKS as a framework has many more features to offer (Kafka, Knative, OpenAPI, etc.) so this is just the start of a new testing platform for BDD testing in Cloud-native environments!
Please give feedback, ideas and of course contributions to this. Feel free to add your thoughts on the YAKS repository by opening new issues or even share your appreciation with a star on GitHub.

EUR/USD technical analysis: 50% Fib capping upside, bearish hammer on D1
by Omkar Godbole- EUR/USD's bounce seems to have stalled at a key Fibonacci level.
- Wednesday's hammer candle is warning of an impending bearish move.
EUR/USD's recovery rally from recent lows below 1.10 has stalled around the key Fibonacci level and a pullback could be in the offing.
The currency pair has repeatedly failed to beat 1.1082 – 50% Fibonacci retracement of 1.1175/1.10989 – in the last three days.
More importantly, EUR/USD created a bearish hammer candle on Wednesday, warning of an impending bearish move.
The combination of persistent failure at the key level and bearish candlestick pattern indicates the market will likely test dip demand with a pullback to 1.1050. Acceptance below that level would validate Wednesday's bearish hammer and shift risk in favor of a re-test of the recent low of 1.0989.
A bullish revival needs a close above 1.1082 (50% Fib + hammer's high). The pair is currently trading at 1.1078, representing marginal gains on the day.

Load data¶
To start playing around with the functions from these packages we will
use the
palmerpenguins
data set. This simple data set has both continuous and categorical
variables that make it perfect for showcasing how different functions
work.
require(dplyr)
require(tidyr)
penguins_url = 'https://raw.githubusercontent.com/allisonhorst/palmerpenguins/master/inst/extdata/penguins.csv'
dat = read.csv(url(penguins_url), stringsAsFactors = TRUE)
dat = dat %>% drop_na()

General plotting with ggpubr
¶
require(ggpubr)
require(ggplot2)
ggpubr
allows to make insightful plots quickly for exploration that in
turn can be further customized thanks to being built on top of
ggplot2
.
These are useful links for using this package:
Next, we will try to answer different questions using this library and
ggplot2
.
How many penguins of each species did we observe in total?¶
ggpie(dat %>% count(species), x = 'n', fill = 'species')
How many penguins of each species and sex did we observe across the different islands?¶
ggbarplot(dat %>% count(species, sex, island), x = 'species', y = 'n', fill = 'sex',
label = TRUE, position = position_dodge(0.7), facet.by = 'island', palette = 'lancet')
What are the distributions of flipper lengths considering penguin species, sex and islands of origin?¶
gghistogram(dat, x = 'flipper_length_mm', fill = 'sex', facet.by = c('species','island'))
Alternatively, we can use stripcharts charts:
ggstripchart(dat, x = 'island', y = 'flipper_length_mm', color = 'sex', facet.by = 'species', alpha = 0.5, position = position_jitterdodge(), add = 'median_iqr', add.params = list(color='black', group='sex', size=0.2))
Are the differences of body mass between sexes significant if we control for species and island?¶
ggstripchart(dat, x = 'island', y = 'body_mass_g', color = 'sex', facet.by = 'species', alpha = 0.5, position = position_jitterdodge(), add = 'median_iqr', add.params = list(color='black', group='sex', size=0.2))+
stat_compare_means(aes(color = sex), label = "p.signif", method = 'wilcox.test')
What is the relationship between flipper length, body mass and bill length?¶
ggscatter(dat, x = 'flipper_length_mm', y = 'body_mass_g', color = 'bill_length_mm', alpha = 0.5)
Could we have sampling bias in the relationship between flipper length and body mass?¶
ggscatter(dat %>% mutate(year=factor(year)), x = 'flipper_length_mm', y = 'body_mass_g', alpha = 0.5, color = 'year', ellipse = TRUE)
What is the spearman correlation coefficient between body mass and flipper length?¶
ggscatter(dat %>% mutate(year=factor(year)), x = 'flipper_length_mm', y = 'body_mass_g', alpha = 0.5, color = 'year',
add = 'reg.line', conf.int = TRUE,
cor.coef = TRUE,
cor.coeff.args = list(method = 'spearman', label.sep = '\n')) +
theme(aspect.ratio = 1)
Create and save a figure¶
fontsize = 6
labsize = 2
# overview number of observations of every sex across islands and species
p1 = ggbarplot(dat %>% count(species, sex, island), x = 'species', y = 'n', fill = 'sex',
label = TRUE, lab.size = labsize,
position = position_dodge(0.7), facet.by = 'island', palette = 'lancet') +
ylim(NA, 68)
# sex-related body mass distributions across islands and species
p2 = ggstripchart(dat, x = 'island', y = 'body_mass_g', color = 'sex', facet.by = 'species',
alpha = 0.5, position = position_jitterdodge(), add = 'median_iqr',
add.params = list(color='black', group='sex', size=0.2),
palette = 'lancet')+
stat_compare_means(aes(color = sex), label = "p.signif", method = 'wilcox.test', size = labsize)
# association of flipper length and body mass
p3 = ggscatter(dat %>% mutate(year=factor(year)), x = 'flipper_length_mm', y = 'body_mass_g', alpha = 0.5, color = 'year',
add = 'reg.line', conf.int = TRUE,
cor.coef = TRUE,
cor.coeff.args = list(method = 'spearman', label.sep = '\n', size = labsize)) +
theme(aspect.ratio = 1)
p1p2 = ggarrange(p1 + theme_pubr(base_size = fontsize), p2 + theme_pubr(base_size = fontsize), ncol = 1, common.legend = TRUE)
fig = ggarrange(p1p2, p3 + theme_pubr(base_size = fontsize), widths = c(2,1), heights = c(2, 1), labels = 'AUTO')
# save
ggsave('images/myfig.png', fig, width = 15, height = 10, unit = 'cm')
Heatmaps with pheatmap
¶
A part from ggpubr
, one of the most common packages to visualize
multiple types of data altogether is pheatmap
, which allows to combine
hierarchical clustering of rows and columns with continuous and
categorical data.
require(pheatmap)
# we are only interested in numeric columns
cols_oi = c('bill_length_mm','bill_depth_mm','flipper_length_mm','body_mass_g')
rownames(dat) = 1:nrow(dat)
pheatmap(dat[,cols_oi], scale = 'column', show_rownames = FALSE, annotation_row = dat[,c('species','island'),drop=FALSE])
Phylogenetic trees with ggtree
¶
Trees are another very common plot to visualize hierarchical patterns.
Here, we will use
ggtree
to visualize the phylogenetic relationships extracted from a multiple
sequence alignment of TP53 across mammals.
Basic tree¶
require(ggtree)
set.seed(100)
tree <- rtree(50)
ggtree(tree, layout="circular") + geom_tiplab()
Tree and multiple sequence alignment of TP53 amino acids¶
We will follow Russell J. Gray’s approach.
require(seqinr)
require(ape)
# create tree from alignment
fasta_file = file.path(here::here(), 'data', 'raw', 'TP53-mammals-alignment-aa.fa')
aln = read.alignment(fasta_file, format = 'fasta', whole.header=TRUE)
D = dist.alignment(aln)
tree = njs(D)
# plot tree with MSA
tree_plot = ggtree(tree)
msaplot(tree_plot, fasta = fasta_file) + ggtitle('tree with MSA')

Fri Feb 25, 2000
In the middle of the flood-ravaged Northern Province on the bus…
Well, we just scraped through Beitbridge before it closed, but some of the roads were impassable and the bus broke down, so this bus will be 14 hours late.
Add that on to the 12 hours already travelled and that makes for a long journey with very sore legs/back/neck. Serves me right for barging through the worst floods in 50 years. Leaving thousands homeless. Perpetuating diseases like Cholera and Malaria. Africa.
Yeah, so that address at the top [redacted] is a guy from Quebec City, in case I ever go there. Really nice guy. I’ve met so many great people on this trip. I wish I could have afforded to go to Malawi and Tanzania.
Yesterday, I phoned Colleen, read the paper, and my taxi that I called never pitched. So I had to run out into the street and flag down a minibus which took me as far as Fife St. Then I ran (with my luggage) the rest of the way. You know I couldn’t backpack if I was much older.
I must do some email soon. Maybe not a long one at Colleen’s ‘cause they’re too hospitable and have too many people taking advantage of that. I should contact some key people, like parents, to let them know I’m okay.
Much, much later…
 Got in about eight hours after expected. Phoned Colleen and her maid told me she’s sleeping - I think she’s too afraid to wake her up. Feel really bad about imposing on them - there are buses to Durban tomorrow, but I don’t have any money, so I would have to borrow and pay back. Thomas Cooke closes at four and they have no commission. I think I must phone again in ten minutes. I don’t want to sit here for another two hours. I’m so knackered.
All’s well that ends well…
Just had a hot bath and a shave and washed my hair and ate chops and sweet potatoes, Italian sweet kisses and drank two beers… I feel absolutely heavenly!
 I went in and changed money and booked my Durban bus for tomorrow morning. Caught a bus back here. Managed to get Gareth to pick me up tomorrow after a few calls to others who couldn’t on such short notice. Good guy, really good guy.
Checked my emails - had 16 messages. Nothing too exciting happening in Vancouver as usual. Not the drama here with floods and power struggles with greedy dictators. They closed Beitbridge today, so I really did just squeeze through before the Limpopo swamped the bridge.

===============================================================================
You can use this function to conditionally define functions, see: http://
php.net/manual/en/functions.user-defined.php
For instance Wordpress uses it to make functions "pluggable." If a plugin has
already defined a pluggable function, then the WP code knows not to try to
redefine it.
But function_exists() will always return true unless you wrap any later
function definition in a conditional clause, like if(){...}. This is a subtle
matter in PHP parsing. Some examples:
Prints:
foo defined
defining bar
calling bar
calling baz
PHP Fatal error: Call to undefined function qux()
Any oddities are probably due to the order in which you include/require files.
===============================================================================
It should be noted that the function_exists check is not relative to the root
namespace. This means that the namespace should be appended to the check:
===============================================================================
PHP supports nested function based on certain criteria.
Please look over the code.
function Media(){ }
function Audio()
{
echo "Plugged Audo 5.1:
";
function Volume()
{
echo "Volume controls:
";
function Equalizer()
{
echo "Equalize Bands:
";
}
}
}
//Call to nested functions
Audio();
Volume();
Equalizer();
if(function_exists('Volume')):
echo "TRUE";
else:
echo "FALSE";
endif;
Case 1: //Result :Works Well
--------
Audio();
Volume();
Equalizer();
Case 2: //Results Notice Error. Root function Audio must be called first.
--------
Volume();
Case 3: //Results Error. Root function Volume must be called.
--------
Audio();
Equalizer();
Note :
The nested function should be called based on their order used.
In our example when Audio is not called and instantly when we try to call
Volume puts under error.
Even though there is an possibility to use nested functions in PHP. It looks
overhead to do so. Better to avoid in logical ground of script.
Tested on PHP 5.5.32
===============================================================================
Functions within a function are better off as anonymous returns from
create_function(), unless you want to be able to call it elsewhere.
However, I have used this in skinning: I use alert_box() to display certain
errors, like a faulty SQL query. This simply calls display_alert(), which is
defined in my skin scripts. However, alert_box() is sometimes called before I
know which skin to load, so it has its own functionality which it uses if
function_exists('display_alert') returns false.
===============================================================================
I stumbled over the same problem as "eddiec" (users not able or not willing to
use "_once"-suffixes).
A possible alternative explanation for the behavior:
If a file is included, it is possibly parsed every include-time.(?)
While parsing, every function in global scope is tried to register. THIS gets
wrong, when multiple times included, and it produces an error.
If functions are defined within block scopes, their registration seems to be
delayed until execution of such a block. Thus, not the function
"function_exists" functions wrong, but simply the philosophy of the interpreter
produces such results.
Thus, the same effect can be achieved by simply putting block braces around the
contents of an include_once file:
if (function_exists('function_in_question')) return;
{
function function_in_question(...)
{
...
}
...other stuff
}
...which is equivalent to...
if (!function_exists('function_in_question'))
{
function function_in_question(...)
{
...
}
...other stuff
}
===============================================================================
If you use suhosin.executor.func.blacklist instead of disabled_functions in
your php.ini, function_exists will return true for a disabled function. I used
this to have the same beahviour with suhosin.executor.func.blacklist and
disabled_functions:
===============================================================================
function_exists() does not cache its query internally.
by executing the following code
$funcs = \array_shift(\get_defined_functions());
$l = new \core\utiles\loadTime;
$times = 0;
$l->start();
for($index = 0; $indexstop();
echo "$times took : $s";
# the output would be
$> 2365444 took : 0.70324
By executing the
$funcs = \array_shift(\get_defined_functions());
$l = new \core\utiles\loadTime;
$times = 0;
$l->start();
static $func_check = array();
for($index = 0; $indexstop();
echo "$times took : $s";
# the output would be
$> 2365444 took : 0.53446
There is a 0.16878 seconds improvement, when you use static array to cache
methods existence.
===============================================================================
I would like to comment on the following post:
A note of caution: function_exists() appears to be case-insensitive (at least
as of PHP 4.3.8). e.g.:
I believe that function calls itself are case insensitve, so this function is
returning a valid truth. PHP doesn't care about cases.
===============================================================================
This is not going to go down as you might expect it should (even if you play
smart and require/include_once):
This, however does work:
Does it have anything to do with PHP parse/execute phases or global/local scope
or those curly brackets or something else, I have no idea, but the latter ugly
son works, while the former bombs out claiming that 'my_function' is already
defined.
Thought this might save someone a few minutes of debugging time...
===============================================================================
I, too, was wondering whether is_callable or function exists is faster when
checking class methods. So, I setup the following test:
is_callable = ".($callableIsTrue ? "TRUE" : "FALSE").", \n";
echo "function_exists = ".($existsIsTrue ? "TRUE" : "FALSE")."
\n";
echo "
Did 10000 is_callables in ".$timeIsCallable." seconds";
echo "
Did 10000 function_exists in ".$timeExists." seconds";
?>
This gives the output :
is_callable = TRUE, function_exists = FALSE
Did 10000 is_callables in 0.0640790462494 seconds
Did 10000 function_exists in 0.0304429531097 seconds
So the fact that function_exists is twice as fast is slightly over shadowed by
the fact that it doesn't work on class methods, at least not as far as I can
tell.
===============================================================================
Note that function_exists will return TRUE in the following situation,
presumably because the function "testfunc" was defined when the script was
PARSED/ITERPRETED, before the function_exists call was made at RUNTIME:
So, this construction is not useful for preventing testfunc from being multiply
defined if the script is muliply included or required.
However, the following construction DOES work to prevent multiple defines of
testfunc:
CONTRAST this with similar uses of defined() which is completely runtime
evaluated. These both work:
AND...
// An example of how to use:
';
echo $if_is_disabled["s"]; // return 1 or 0
?>
===============================================================================
function_exists will return false for functions disabled with the
disable_functions ini directive. However those functions are still declared so
trying to define them yourself will fail.
The above will issue a "Cannot redeclare readfile()" fatal error if readfile
was disabled with disable_functions.
===============================================================================
":" $funcName doesn't
exist
";
}
?>
/*O U T P U T
A exist
B exist
C doesn't exist
D doesn't exist
*/
===============================================================================
to avoid direct calls this can be better than function_exists
in the parent file:
and in the target file:
===============================================================================
To prevent direct calls to included files i use the following technique.
In the main file create an empty function with a random name. Like so:
Then check for the existence of this function within your include:
Simple but effective.
===============================================================================
This can be used to conditionally define a user function. In this sense, it can
act as a sort of inline include_once().
For example, suppose you have a function A that calls function B. B is only
used inside function A and is never called from anywhere else in the script.
It's logical (and perfectly legal in PHP) to define B inside of A's definition,
like so:
Without the function_exists test, you would get a fatal error the second time
you called A, as PHP would think you were trying to redefine B (not legal in
PHP). The placement of the test is also important. Since the if block is
executed sequentially, like any other block of code, it must come before any
call to the function defined within.
===============================================================================
to php at fluidthoughts dot com
you aren't comparing against false, that if compares against true, so it's
going to return that, as false != true
true being 1, True, (bool)True, etc.
false being 0, False, Null, etc
This..
Works.
Alternatively, to enter upon existance..
Use your code. Since they dont exist, it wont enter..
===============================================================================
function_exists returns false on NULL and empty string:
Neither of the echo statements happen when I run this.
===============================================================================
i was wondering whether is_callable or function exists is faster when checking
class methods.
is_callable(array('foo', 'bar'));
function_exists('foo::bar');
my results when doing each operation 10000 times with a simple test class were
the following:
is_callable: 0.28671383857727 seconds
function_exists: 0.14569997787476 seconds
(following tests have proved this to be true).
thus you can see, function_exists is twice as fast as is_callable.
===============================================================================
to bob at thethirdshift dot net
regarding is_callable vs function_exists.
using your code
is_callable = TRUE, function_exists = FALSE
Did 10000 is_callables in 0.0443360805511 seconds
Did 10000 function_exists in 0.0111110210419 seconds
then we replace
is_callable(array('test','test'));
with
$callarray = array('test','test'); // place this outside for-loop
is_callable($callarray);
is_callable = TRUE, function_exists = FALSE
Did 10000 is_callables in 0.0314660072327 seconds
Did 10000 function_exists in 0.0120670795441 seconds
then we replace
is_callable(array('test','test'));
with
is_callable('test','test');
is_callable = TRUE, function_exists = FALSE
Did 10000 is_callables in 0.00991606712341 seconds
Did 10000 function_exists in 0.0113790035248 seconds
I hope you can see that loop-testing functions is not so simple. :)
===============================================================================
to brooklynphil at hotmail dot com:
Your post is misleading, namely the 3rd and last speedtest you describe is an
unfair comparison:
The value of the 2nd parameter $syntax_only is 'test' and this evaluates to
boolean true. In other words, this is exactly the same as calling the function
like this:
Of course this will be faster because is_callable only does a very basic
syntaxcheck. From the documentation: 'It will only reject simple variables that
are not strings, or an array that does not have a valid structure to be used as
a callback.'
If you omit this erroneous 3rd test, then according to your examples
function_exists is 2 to 4 times faster.
I hope you can see that loop-testing functions is not so simple. :)

PyPlotter - A Python/Jython Graph Plotting Package. Manual
|
5.1 Overview
PyPlotter basically consists of two parts, a front end part and a back
end part. The front end part comprises the high level classes to plot
cartesian graphs or simplex diagrams. These are the class Cartesian
from the Graph module and class Diagram from
the Simplex module. The backend part is a simple driver
interface that is defined in the Gfx module. There exist
several implementations of this driver interface for different graphical
user interfaces. They are located in the modules named **Gfx.
Package PyPlotter consists of the following Modules:
- Compatibility
- A helper module to ensure compatibility with different Python versions
(Verions 2.1 through to Version 2.4) as well as compatibility with
Jython 2.1 .
- Colors
- A helper module for dealing with colors. If contains a list of well
distinguishable colors (useful if drawing many graphs on one single
plain) and a few filter functions that help assigning similar color
shades to graphs that belong to the same of several groups.
- Gfx
- This module defines the driver interface (class Driver).
It also contains class Pen to store a set of graphical attributes
such as color, line width etc.
- **Gfx
- These modules contain implementations of Gfx.Driver for
different GUIs. There are drivers for the following GUI toolkits:
- tkGfx for the tkinter GUI toolkit that comes with
the Python standard distribution.
- qtGfx for the qt GUI toolkit (www.riverbankcomputing.co.uk/software/pyqt/).
qtGfx tries to import qt version 4, but falls back on version
3, if version 4 of qt is not present.
- wxGfx for the wxWidgets GUI toolkit (www.wxwidgets.org).
- gtkGfx for the gtk GUI toolkit (www.pygtk.org).
- awtGfx for the Java awt/swing GUI toolkit under
Jython, the Python version running under the Java JVM.
- psGfx for postscript output that can be written
to a file.
- Graph
- Contains the high level class Cartesian for drawing graphs
on a cartesian plain. It also contains a number of intermediate level
classes for mapping virtual to screen coordinates etc.
- Simplex
- Contains the high level class Diagram for drawing simplex
diagrams of population dynamics. Within in this module also some intermediate
classes for simplex drawing and coordinate transformation are implemented.

TRAINING DAY
Reviewed by Harvey Karten Warner Bros./Village Roadshow Director: Antoine Fuqua Writer: David Ayer Cast: Denzel Washington, Ethan Hawke, Eva Mendes, Charlotte Ayanna, Tom Berenger, Harris Yulin, Raymond J. Barry, Cliff Curtis, Emilio Rivera Screened at: Kips Bay Thea., NYC 10/7/01
Watching "Training Day," which as the title illustrates takes place during a single 24-hour period, reminded me of my first day of teaching in a New York City high school. Antoine Fuqua ("Bait," "The Replacement Killers") gives us one intense police dramas with the marvelous Denzel Washington's going increasingly over the top in the role of rogue detective Alonzo Harris. Though everything appears to hit the fan about a half hour into the picture, Fuqua calibrates the potent story of David Ayer ("The Fast and the Furious") so that we can overlook the lurid and contrivance-soaked conclusion and leave the theater with the feeling that maybe the cops who are good guys can really defeat the forces of iniquity.
The story starts off with a patient exposition showing us that perhaps Jake Hoyt (Ethan Hawke) is not choir-boy idealistic despite his conviction that drug pushers are the scum of L.A. and that he has a calling to rid his city of them. His wife had recently given birth, they're living in a cramped apartment, and he wants to be promoted to detective in order to move his family to a more capacious house. You can see Hoyt's opening-day tensions as he reluctantly drags himself out of bed, talks to his prospective mentor Alonzo on the phone peppering his answers with "sir," and sits dumfounded in the morning coffee-shop rendezvous with his new boss as Alonzo focuses on the newspaper and dresses down his new acolyte for speaking and ruining his concentration.
Yet Jake is in awe of the big man, all the more as he watches Alonzo traipse around his broad geographical precinct like a warlord ruling over his serfs. The expression "what a difference a day makes" hits home for young, ambitious and naive Jake as the song title has probably not quite succeeded in doing to anyone else with such furor. As Jake follows his boss' lead to some extent, using a choke hold on one of two pond scum people in an L.A. back alley who are in the processing of raping a fourteen-year-old girl, Alonzo himself ups the ante in dealing with some of the higher-ups in the drug trade, with corrupt apparatchiks in local government including a fierce, cigar-smoking D.A. (Harris Yulin), and in scaring the hell out of some college kids slumming by driving through the ghetto to buy marijuana.
As Alonzo hones in the worst of L.A. citizenry, I'd be curious to know what various denizens of the America theater audience. Would they cheer this direct, extra-legal action, a kind of the-end- justifies-the-means philosophy as they did while Charles Bronson's character in Michael Wiener's "Death Wish" did in offing muggers on the subway rather than bothering to arrest them and take his chances on justice before a jury? After all Denzel Washington is awfully persuasive as one of our finest actors, perfectly able to play the good guy as he did in as a coach in "Remember the Titans," as a South African activist, Steven Biko, in "Cry Freedom" and once more in a fiery supporting performance in "Glory." Though his role this time does not call for the complexity he demonstrated while the incarnation of Malcolm X in the film of that name, he does a smashing job in his most villainous role. Ethan Hawke, recently performing in the title role of the indecisive prince in Michael Almereyda's "Hamlet," pulls off a role not entirely dissimilar.
There's an unfortunate tendency to end action-adventure pictures with extreme, Bonnie-and-Clyde violence. In Jonathan Mostow's "Breakdown," Red Barr (J.T. Walsh) is done in by having a truck thrown on him by Jeff Taylor (Kurt Russell) and more recently a bad guy is buried alive in "Don't Say a Word." A similar concluding scene threatens to destroy the quality of what went on before. But thanks to a stellar, riveting performance by Denzel Washington in a villainous role that so many actors would kill for and a remarkable show by Ethan Hawke as his bland foil, "Training Day" is an action police drama which is as good as a Hollywood genre pic can get.

A "closure" is an expression (typically a function) that can have free variables together with an environment that binds those variables (that "closes" the expression).
Closure is where a function remembers what happens around it.
function f1(){
var n=999;
alert(n);
}
f1();// 999
// Here n is not accessible.
No closure here
n is not accessible after f1 finishes
function f1(){
var n=999;
function f2(){
alert(n);
}
return f2;
}
var result=f1();
result(); // 999
f2
formed a closure
n is still accessible after f1 finishes
Without closure |
With closure |

links[i].onclick = function() {
alert(i+1);
}
}
}
main(document.getElementsByTagName("a"));// assume there are 6 links
Expected: alert 1,2,3,4,5,6
Actual: alert 6,6,6,6,6,6
All links want to access "i"
But there is only one "i" in memory
So all links give same result.
function main(links) {
for (var i=0; i<links.length; i++) {
links[i].onclick = (function(j) {
return function() {
alert(j+1);
}
})(i);
}
}
main(document.getElementsByTagName("a"));
Use inner method as return value
Use local variable of outter function as param for inner function
Each function has its own param
Often happens in IE6
Don't use closures unless you really need closures semantics. In most cases, non-nested functions are the right way to go.

Value resolvers are used when evaluating expressions. You can register a custom io.quarkus.qute.ValueResolver programmatically. See org.acme.qute.samples.CustomValueResolverSample.registerResolver(EngineBuilder) for more details.

Add the following dependencies:
io.ebean ebean 13.6.5 io.ebean ebean-test 13.6.5 test
ebean-test should be added as a test dependency. This configures Ebean for running tests including automatic use of docker containers for Postgres, MySql, Oracle, SqlServer, Hana + support for H2 and SqlLite.
Refer to: docs / testing
In the build / plugins
section:
tiles-maven-plugin
to perform build time enhancementmaven-compiler-plugin
to register the querybean-generator annotation processor.io.repaint.maven tiles-maven-plugin 2.22 true io.ebean.tile:enhancement:13.6.5 org.apache.maven.plugins maven-compiler-plugin 3.10.1 ... io.ebean querybean-generator 13.6.5
The maven tile above will enhance the code at build time for both src/main
and src/test
. This is simpler than defining the plugin in the traditional (non-tile)
fashion and is the preferred approach.
If you want to specify the maven enhancement plugin in 'normal' non-tile fashion see maven plugin.
Note that if there are no other annotation processors (e.g. mapstruct) then instead of
explicitly registering the querybean-generator
with the maven-compiler-plugin
we can instead just add it as a dependency with provided scope.
Add the dependency for the JDBC Driver(s) you want to use.
When using Kotlin we need to use KAPT (Kotlin annotation processing) to generate Kotlin query beans.
The recommended way to do this is via the io.avaje.kapt
maven tiles as this makes it easier to add additional annotation processors
(like DInject for dependency injection for example).
Add the maven tiles plugin into the build / plugins
section of the pom.xml
with the tiles for:
io.repaint.maven tiles-maven-plugin 2.22 true io.ebean.tile:enhancement:13.6.5 io.avaje.kapt:compile:1.1 io.avaje.kapt:querybean-generator:1.1
We can add other additional annotation processors by adding tiles, for example:

The Internet Is Already Obsessed With The Deeply Chaotic ‘Hot Ones’ Kristen Stewart Interview
by Joseph EarpKristen Stewart is having a moment.
The one-time Twilight star has spent the last six or seven years choosing only roles that allow her to burn the entire project down. She is in auteur in her own right, a little shimmer of chaos that can make any line feel unusual, and strange, and alien. She never behaves like a real human being. That’s what makes her perfect.
Hell, she’s even imagined to impress critics in the somewhat well-reviewed Charlie’s Angels film — and that’s not exactly a role that you’d expect to necessarily pop. In the hands of anyone else, it’d be a run-of-the-mill action role.
To promote that film, Stewart appeared this week as a guest on Hot Ones, the wildly popular internet talk show that sees celebrity guests eat a line of increasingly spicy wings.
To say that she handled the wings well is to understate things. Barely breaking a sweat, Stewart nimbly hopped through questions, reflected on her many outfits, and contended with the great weight of celebrity.
Oh, and she did it all while being deeply, deeply chaotic. Because that is the Kristen Stewart way.
Like, I’m talking ‘eating wings with a knife and fork’ level chaotic. Bear witness to it here:
Predictably, ever since the interview has dropped, the internet has taken on Stewart’s appearance on the show as a symbol of her deep relatability. After all, we’ve all had a raucous emotional trip, like Stewart…
…we’ve all nervously shimmied in anticipation…
…and we’ve all made fun of our good friend Shia LaBoef for his Hot Ones appearance.
Okay, maybe not the last one. But the rest still stands: Stewart is the OG relatable chaos queen, and we thank her for every moment of joy that she adds to our lives.

We harness the enormous skill, might and strength of the South African private legal fraternity to cases

South African who are unable to pay for their own private legal representation.Section 34 of our
Constitution, giving everyone the right to have any dispute resolved by the application of law decided in a
fair public hearing before a court, or… another independent and impartial tribunal or forum, has no meaning
whatsoever, if a person is unable to afford representation. ProBono.Org has as its goal, the creation of
sufficient free legal representation for all who need it.
