The VIPS-model stores various meta-information for each component, e.g. KL bounds, the target distributions for the KL constraint and some debug data like the history of achieved rewards.
This function will enlarge the matrices/vector that store this meta-information in order to account for newly added components.

Remove all public interfaces used for testing the application.
Test interfaces add extra functionality that is not intended for the released application. Often these interfaces will be used by a test team to gain information or drive functionality that would be dangerous in the hands of an attacker.
If your application contains test interfaces remove them before deployment.
To remove all test interfaces:
Identify all test APIs. Enumerate all public APIs. Identify which APIs are intended for application use and which APIs are intended for test purposes. Ideally these interfaces will already be documented properly and can be discovered through specifications.
Remove the test interfaces. Code removal is a straight forward procedure. Once the test code is identified, it should be isolated from the application and removed from your code base.
The following code shows the user management system for an application. Because the class contains test APIs, it is possible for a malicious user to execute untested code and possibly exploit any vulnerabilities in it.

The Taiwanese-American identity is a vastly varied one and at times a divisive issue. Moreover, there is political and cultural apathy among many Taiwanese, and under-representation in our communities. Yet, from those who barely identify themselves as Taiwanese, to those who feel passionately about Taiwanese culture, they are all still unified under a common background. Those with the Taiwanese-American identity have the potential to develop into a tight-knit community and strong leaders with a unified voice in this nation.
The Taiwanese American Student Association at the University of California, Berkeley is dedicated to promoting the unity and cooperation of Taiwanese-Americans in the community, the presence of the Taiwanese American community in local and national arenas, and the culture and identity of Taiwanese-Americans. TASA will hold events bringing together men and women of all backgrounds and ideals, uniting them by a common culture and interest, and together building the awareness of Taiwanese-Americans of their own identity and culture, knowledge in their heritage, and strong recognition from others.

"As a power user, I post videos on TikTok, and spread my videos reach by using hashtags!" -Sonya
Home Page
View Her Persona Profile
Here's an example of how she uses TikTok


To start I need to explain an ethical decision I had to make. Now this alone is hard enough to do as decisions that draw my ethics in to question are rare for me, that or they appear frequently and I don't take too long to think on them but here goes. A few years ago a friend and I were having a conversation and the topic of his girlfriend had come up, this was not uncommon as at the time she was basically his whole world and for her part when they were together she could do no wrong in his eyes. However at the time I had recently learned that she was unfaithful and that had been going on for a while when they were together, I have a very short fuse when it comes to both lairs and traitors and this girl was both, so there was the choice sit and do nothing or tell him that the person who held his heart was playing with it . Being who I am and that the topic had just come up I told him the truth now the conversation is kind of foggy in my mind but I know the outcome he hit me, just once, then told me never talk bad about his girlfriend again then stopped talking to be about a year. What happened or so I heard a few weeks after that happened he started asking questions that she didn't want to answer and he eventually caught her with someone else. Everyone who gets to know me learns real quick I'm always going to be honest with them even if it hurts.
Your culture is based on the people you hang round be it family or friends or the people you work with, the people I kept close constantly changed but I always had animals around be it cats or dogs sometimes it was birds my core values and what I based my identity on comes from them, animals were always honest and trusting and could be incredibly loyal if you treated them well and so that's how I based my core be honest and be loyal.
The animals also influence my values I learnt to value freedom form birds , from dogs I learnt stubbornness can sometimes be a very useful in getting what you want but also know when to drop it even if its the only thing you want in the world at that moment, and the value of tolerance from cats the put up with something up until the don't and you can usually see that last part coming from a good while away.
I can be very stubborn when it comes to learning things, at times I will sit for hours trying to understand a problem until I get it, the only problem is that that stubbornness can lead me to getting stuck for longer than I should be cause I know I can get it I just need a little more time, even if the easiest way to get unstuck is just to ask for help.

Cacti - T. peruvianus, Harmaline & Cannabis
In order to boost the alkaloid absorption of this Elixir, I procured freebase crystals of a Peganum Harmala seed extract. As you kitchen alchemists know, Peganum seeds have perhaps the highest concentration of MAOIs in one of its active compounds (Harmaline). Now, I have tried every mode of Peganum I know: raw, ground up seeds, a water extract, and a 5x alcohol extract. The raw seeds produce an unfathomable nausea and convulsions of stomach pain, all while the MAOIs rise up to crack open the cerebral connections. Highly unadvisable. The freebase crystals are by far the easiest and most concentrated form of taking Peganum as an MAOI.
Medicine was prepared according to standard alcohol extraction. Poured ~30grams of dried Peruvianis powder into a large canning jar, which I gradually filled with Everclear (95% alcohol). After 24 hours, Cactus infused alcohol was suctioned out using a turkey baster, and then placed into a round pyrex glass dish. Rather than allowing the 24-48 hours of evaporation, I let it evaporate for about 12 hours, filtering the solution and putting the alcohol-only portion in one glass, while leaving cactus powder in another glass. Not allowing the full evaporation, as well as ingesting the actual powder, proved to be immense gastrointestinal mistakes that consumed most of the journey.
After a ritual bath, MAOI crystals were imbibed. All dietary restrictions for MAOIs respected – do not ignore this!! I then choked down the sludge of soy-milk/cactus powder, followed by drinking raw, unadulterated Cactus-infused-Everclear. Hands down, this is the most profoundly bitter and overwhelmingly harsh herb to drink on goddess’ green Earth. Time: approx 8 PM, PST.
Things get bizarre. I live on the edge of a forest in the beautiful hills of central Oregon – an amazing place for these journeys. Nausea – good god, sweet gods, what pain. I lay outside, accompanied by a small pipe with pouches of tobacco and cannabis. Dusk descends. I’d listen to random music – Gregorian chants, Native American folk music – chant along, sometimes sing, cry, and the beauty of whatever “melody” poured forth from my body was heartwrenching. Eventually inner silence would envelop, and the subtle winds would course thru my flesh along with the towering reeds, billowing Douglas-firs…. I felt no more special than soil or grass. Humbled joy – perfection.
Keep in mind that while these epiphanies arose, the most excruciating nausea and stomach pain humanly possible racked my body, due to ingesting the actual cactus powder. I forgot to get water, usually tobacco/cannabis give me bad cottonmouth, but I somehow discovered “pore breathing” in which I absorbed the water particles in the wind and air. This went on for an hour or two, continually smoking the herbs to help with my stomach and to ground the journey, while never feeling dehydrated at all.
Back inside, the convulsions of stomach pain. Somehow I can’t vomit though. Forcing myself would have invoked that, but that felt not right. I lay on the ground, dazed. I then chew 2 teabags of Coca as part of the shamanic infusion. Delicious taste of Earth and nitrogenous soil in my gums. Any sensory input was overpowering, ecstatic, bewildering, like an infant perceiving life for the first time. Moving a few feet equals a journey of 10,000 miles. Walking ¼ a mile near the forest is interstellar. Suddenly when my thinking stops, I leave my body and am fluidly traveling through astral space. Anyone with tendencies towards astral projection, out of body experiences, lucid dreams, etc. will find their etheric/subtle body drifting away effortlessly. Points in space/time traversed at speed of thought.
The Elixir seems perfectly attuned to the nervous system of whoever She flows through. The most subtle, mundane fact of my life would manifest for me to notice, or a random comment spoken by a friend years ago would shake my body with gentle laughter. Moments later I’d directly receive information about the holographic and metaphysical nature of the cosmos that defies the intellect’s ability to comprehend. The presence of ascended masters and long-dead Shamans scintillated in the air, the sky, the walls of my bedroom, in my flesh.
Be still – surrender. Be as simple as waving grass. Know the frog’s dusk song. Be the pain, sorrow, torment and ecstatic joy of the entire cosmos at the same moment, cosmically ebbing in unfathomable crescendos.
My reflection in the mirror quite frankly was a bit scary. Around dawn, the shadows meeting the dim early light would create bizarre movements and eddies. It still invoked a deep humor rising from my belly.
The Cactus, mythically brought to Earth by Saint Peter, is a medicine of astonishing power. She always invokes a kind of psychic death, and there are times I am rather convinced I’d physically die. This Power is said to cleanse the blood, the physiological system, as well as the psychological and spiritual circuits interwoven thru this microcosm of the Universe encased in living flesh. Much of the journey is simply unspeakable.
5:27 PM: nearly 24 hours later, and still no sleep. That may come some day….

Iranian Foreign Minister Says Tehran Ready for Prisoner Swap, 'Ball is in US Court' - Reports
Iranian Foreign Minister Mohammad Javad Zarif tweeted on 7 December that Iran and the United States were conducting an exchange of US-held Iranian scientist Massoud Soleimani and Chinese-American Xiyue Wang detained in Iran.
Tehran is ready for a prisoner exchange, Iranian Foreign Minister Mohammad Javad Zarif tweeted on 9 December, adding that "the ball is in the US' court".
Government spokesman Ali Rabiei said at a briefing earlier in the day that Iran is ready to exchange more prisoners with the United States following the successful swap last week, with the goal of eventually exchanging all prisoners in the countries respectively.
According to the official, Iran released Chinese-American Princeton scholar Xiyue Wang on humanitarian grounds, adding that a message to Iran from an unnamed former US official also played a role in the exchange.
US Secretary of State Mike Pompeo later confirmed that the Chinese-born US citizen, who had been detained in Iran on spying charges for three years, was released by Tehran.
The United States did not make any concessions to the Iranian authorities to make them release Xiyue Wang, a senior official with the US presidential administration told reporters on 7 December.
Wang was convicted on espionage charges and sentenced to 10 years in prison in Iran in 2017. Soleimani, a stem cell expert, was detained in 2018 at Chicago airport for allegedly trying to export biological materials to Iran in violation of US sanctions.

Clawpack Documentation Version 5.0 --- Under Construction! Not yet accurate |
For usage see Using setplot.py to specify the desired plots and Plotting examples in 1d.
Objects of this class are usually created by the new_plotaxes method of a ClawPlotFigure object.
The following attributes can be set by the user:
- name : str
- title : str
The title to appear at the top of the axis. Defaults to string specified by the name attribute.
- title_with_t : bool
If True, creates a title of the form “%s at time t = %s” % (title, t)
- axescmd : str
- The command to be used to create this axes, for example:
- “subplot(1,1,1)” for a single axes filling the figure
- “subplot(2,1,1)” for the top half
- “axes([0.1, 0.1, 0.2, 0.8])” for a tall skinny axis.
See the matplotlib documentation for axes.
- xlimits : array [xmin, xmax] or 'auto'
The x-axis limits if an array with two elements, or choose automatically
- ylimits : array [ymin, ymax] or 'auto'
The y-axis limits if an array with two elements, or choose automatically
- afteraxes : function or str
A string or function that is to be executed after creating all plot items on this axes. If a string, this string is executed using exec. If a function, it should be defined to have a single argument current_data.
The string version is useful for 1-liners such as:
afteraxes = "pylab.title('My custom title')"pylab commands can be used, since pylab has been imported into the plotting module.
The function form is better if you want to do several things, or if you need access to the data stored in current_data. For example:
def afteraxes(current_data): # add x- and y-axes to a 1d plot already created from pylab import plot xlower = current_data.xlower xupper = current_data.xupper plot([xlower, xupper], [0.,0.], 'k') # x-axis # Get y limits from variable just plotted, which is # available in current_data.var. ymin = current_data.var.min() ymax = current_data.var.max() plot([0.,0.], [ymin,ymax], 'k') # y-axis
- show : bool
If False, suppress showing this axes and all items on it.
- new_plotitem(name=None, plot_type)¶
Returns an object of class ClawPlotItem associated with this axes. A single axes may have several items associated with it.
The name specified is used as a dictionary key. If None is provided, one is generated automatically of the form ITEM1, etc.
- gethandle()¶
Returns the handle for this axes.

See the important note below.
"clampToEdge" is the only valid texture wrap for non-power-of-two textures.
To use "repeat", make sure the dimentions of your texture are a power of two. For example 16, 32, 64, 128, 256, etc.
display.setDefault( "textureWrapX", "repeat" )
display.setDefault( "textureWrapY", "repeat" )
local x,y = display.contentCenterX, display.contentCenterY
local o = display.newRect( x, y, display.contentWidth, display.contentHeight )
o.fill = { type="image", filename="fish.small.red.png" }
o.fill.scaleX = 0.1
o.fill.scaleY = 0.1

In the following sections we need to set the postmaster address. This is a combination of the postmaster local part and the main mail domain. The main mail domain is also used as "server display name". This is the way the SMTP server identifies itself when connecting to others. The Postmaster will get an e-mail address <postmaster>@<main_domain>. This address will receive the DMARC "rua" and "ruf" reports. Or in plain english: if receivers start to classify your mail as spam, this postmaster will be informed.

The admin interface is the main Mailu-specific bit, it provides tools to manage your email domains, users, etc.
The API interface is a RESTful API for changing the Mailu configuration. Anything that can be configured via the Mailu web administration interface, can also be configured via the RESTful API. For enabling the API, an API token must be configured. It is not possible to use the API without an API token.


MeasureCamp Cincinnati 2019
- When: April 27th 2019
- Where: 8451
- Who: You!
Overview
- Search: typical approaches and problems
- Recommenders: typical approaches and overview
- Bring search and recommendations together
- A few approaches leveraging elastic search
Search
- Search is the process of ranking content based on a query.
- We are filtering content
- We need good search to:
- Increase engagement
- Address information overload
- Improving discoverability - Unaware of existence or new Content
Typical problems with Search
- A typical search in your document repository is poor
- Out of the box solutions don't consider the whole context available
- Typically uses an inverted index
- A ranking scheme
Enhancing search
- So how can we do better?
- Why is google so good?
- Crowd sources relevence
- We need and often have additional context
Enhancing search
- Simplest approach is boosting
- There are other ways: word2vec
- Word2vec can crowd source via past search history and get additional context
Recommendation Engines
- What does recommendation have to do with search
- Recommenders filter information based on user’s preferences, interest, or observed behavior about item
- We can think of it as a mechanism to improve relevance
Recommendation Engines
- Two main types of recommendation systems
- Content based filtering
- Collaborative filtering
Content Based filtering
- Recommends items based on a similiarty of the items features and user profile features.
- Each item is represented as a set of terms.
- The user profile is represented with the same terms.
- Items that are most related to profile are recommended to the user
- This similarity can be derived by TF/IDF
Representing Content based in ElasticSearch
- Since it can leverage term similarity we can use the elastic search indexes
- Represent the item(movie/show) as ES document
- Features are stored in separate fields
- User becomes the query
- Reference : Recommendation through elastic search lens
Collaborative filtering
- Recommends items based on a similiarty of the item's ratings from other users.
- Premise: users who agreed in their ratings of items in the
past will do so in the future
- Neighborhood Based approaches:
- User-Based approach: group similar users.
- Item-Based approach: group similar items and recommend.
- Or Matrix Factorization is an approach(ALS).
ALS - Alternating Least Squares
- Rij is a rating matrix of Users to Products
- We have a sparse matrix with some cells filled
- The solution predicts missing cells
- It's is decomposed into Uik users with k factors and Pkj products on k factors
- ALS fixes U and predicts P , fixes P and Predicts U
Representing Collaborative filter model in ElasticSearch
- Feature selection in text classification can be applied to item as a document model
- Directly store like items in fields - Recommendations for search (trivial approach)
- Or store the feature vectors in elastic search
- You can use something like Apache Mahout elastictaste plugin
Elastic Search representations
- Docker-compose for elasticStack
- Jupyter Notebook
- Search for recommenSignificant Terms Aggregation
- Directly storing like items
Summary
- Search is recommendation and recommendation is Search
- Think of context to exploit the problem space
- We looked at collaborative and content based filtering approaches
- A combination of strategies will be needed to fine tune and deliver a performant search

Getting Started
The goal of this document is to guide you through the process of creating a simple Dropwizard project: Hello World. Along the way, we’ll explain the various underlying libraries and their roles, important concepts in Dropwizard, and suggest some organizational techniques to help you as your project grows. (Or you can just skip to the fun part.)
Overview
Dropwizard straddles the line between being a library and a framework. Its goal is to provide performant, reliable implementations of everything a production-ready web service needs. Because this functionality is extracted into a reusable library, your service remains lean and focused, reducing both time-to-market and maintenance burdens.
Jetty for HTTP
Because you can't be a web service without HTTP, Dropwizard uses the
Jetty HTTP library to embed an incredibly
tuned HTTP server directly into your project. Instead of handing your service off to
a complicated application server, Dropwizard projects have a main
method
which spins up an HTTP server. Running your service as a simple process eliminates a
number of unsavory aspects of Java in production (no PermGem issues, no application
server configuration and maintenance, no arcane deployment tools, no
ClassLoader
troubles, no hidden application logs, no trying to tune a
single garbage collector to work with multiple application workloads) and allows you
to use all of Unix's existing process management tools instead.
Jersey for REST
For building RESTful web services,
we've found nothing beats Jersey
(the JAX-RS reference
implementation) in terms of features or performance. It allows you to write clean,
testable classes which gracefully map HTTP requests to simple Java objects. It supports
streaming output, matrix URI parameters, conditional GET
requests, and
much, much more.
Jackson for JSON
In terms of data formats, JSON has become the web’s lingua franca, and Jackson is the king of JSON on the JVM. In addition to being lightning fast, it has a sophisticated object mapper, allowing you to export your domain models directly.
Metrics for metrics (duh)
Our very own Metrics library rounds things out, providing you with unparalleled insight into your code’s behavior in your production environment.
And Friends
In addition to Jetty, Jersey, and Jackson, Dropwizard also includes a number of libraries that we've come to rely on:
- Guava, which, in addition to highly optimized immutable data structures, provides a growing number of classes to speed up development in Java.
- Log4j and slf4j for performant logging.
- Hibernate Validator, the JSR-303 reference implementation, provides an easy, declarative framework for validating user input and generating helpful, internationalizable error messages.
- Apache HttpClient and Jersey's client library allow for both low- and high-level interaction with other web services.
- JDBI is the most straight-forward way to use a relational database with Java.
- Freemarker is a simple template system for more user-facing services.
Now that you've gotten the lay of the land, let's dig in!
Setting Up Maven
We recommend you use Maven for new Dropwizard services. If you're a big Ant/Ivy, Buildr, Gradle, SBT, or Gant fan, that’s cool, but we use Maven and we'll be using Maven as we go through this example service. If you have any questions about how Maven works, Maven: The Complete Reference should have what you’re looking for. (We’re assuming you know how to create a new Maven project.)
Add the dropwizard-core
library as a dependency:
<dependencies> <dependency> <groupId>com.yammer.dropwizard</groupId> <artifactId>dropwizard-core</artifactId> <version>0.1.3</version> </dependency> </dependencies>
Alright, that’s enough XML. We’ve got a Maven project set up now, and it’s time to start writing real code.
Creating A Configuration Class
Each Dropwizard service has its own subclass of the Configuration
class
which specify environment-specific parameters. These parameters are specified in a
YAML configuration file which is
deserialized to an instance of your service’s configuration class and validated.
The service we’re building is a high-performance Hello World service, and part of our requirements is that we need to be able to vary how it says hello from environment to environment. We’ll need to specify at least two things to begin with: a template for saying hello and a default name to use in case the user doesn’t specify their name.
Here's what our configuration class will look like:
package com.example.helloworld; import com.yammer.dropwizard.config.Configuration; import org.hibernate.validator.constraints.NotEmpty; public class HelloWorldConfiguration extends Configuration { @NotEmpty private String template; @NotEmpty private String defaultName = "Stranger"; public String getTemplate() { return template; } public String getDefaultName() { return defaultName; } }
There's a lot going on here, so let’s unpack a bit of it.
When this class is deserialized from the YAML file, it will pull two root-level fields
from the YAML object: template
, the template for our Hello World saying,
and defaultName
, the default name to use. Both template
and
defaultName
are annotated with @NotEmpty
, so if the YAML
configuration file has blank values for either or is missing template
entirely an informative exception will be thrown and your service won’t start.
Our YAML file, then, will look like this:
template: Hello, %s! defaultName: Stranger
Dropwizard has a lot more configuration parameters than that, but they all have sane defaults so you can keep your configuration files small and focused.
So save that YAML file as hello-world.yml
, because we’ll be getting up
and running pretty soon and we’ll need it. Next up, we’re creating our service class!
Creating A Service Class
Combined with your project’s Configuration
subclass, its
Service
form the core of your Dropwizard service. The Service
class pulls together the various bundles and commands which provide basic functionality.
(More on that later.) For now, though, our HelloWorldService
looks like
this:
package com.example.helloworld; import com.yammer.dropwizard.Service; import com.yammer.dropwizard.config.Environment; public class HelloWorldService extends Service<HelloWorldConfiguration> { public static void main(String[] args) throws Exception { new HelloWorldService().run(args); } private HelloWorldService() { super("hello-world"); } @Override protected void initialize(HelloWorldConfiguration configuration, Environment environment) { // nothing to do yet } }
As you can see, HelloWorldService
is parameterized with the service’s
configuration type, HelloWorldConfiguration
.
HelloWorldService
’s constructor provides the service’s name:
hello-world
. Also, we’ve added a static
main
method, which will be our service’s entry point. Right now, we don’t have any
functionality implemented, so our initialize
method is a little boring.
Let’s fix that!
Creating A Representation Class
Before we can get into the nuts-and-bolts of our Hello World service, we need to stop and think about our API. Luckily, our service needs to conform to an industry standard, RFC 1149, which specifies the following JSON representation of a Hello World saying:
{ "id": 1, "content": "Hello, stranger!" }
The id
field is a unique identifier for the saying, and
content
is the textual representation of the saying. (Thankfully, this is a
fairly straight-forward industry standard.)
To model this representation, we'll create a representation class:
package com.example.helloworld.core; public class Saying { private final long id; private final String content; public Saying(long id, String content) { this.id = id; this.content = content; } public long getId() { return id; } public String getContent() { return content; } }
This is a pretty simple POJO, but there are a few things worth noting here.
First, it’s immutable. This makes Saying
instances very easy to
reason about multi-threaded environments as well as single-threaded environments.
Second, it uses the Java Bean standard for the id
and content
properties. This allows Jackson to serialize it to the JSON we need. The Jackson object
mapping code will populate the id
field of the JSON object with the return
value of getId()
, likewise with content
and
getContent()
.
Now that we’ve got our representation class, it makes sense to start in on the resource it represents.
Creating A Resource Class
Jersey resources are the meat-and-potatoes of a Dropwizard service. Each resource class
is associated with a URI template. For
our service, we need a resource which returns new Saying
instances from
the URI /hello-world
, so our resource class will look like this:
package com.example.helloworld.resources; import com.example.helloworld.core.Saying; import com.google.common.base.Optional; import com.yammer.metrics.annotation.Timed; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; import javax.ws.rs.core.MediaType; import java.util.concurrent.atomic.AtomicLong; @Path("/hello-world") @Produces(MediaType.APPLICATION_JSON) public class HelloWorldResource { private final String template; private final String defaultName; private final AtomicLong counter; public HelloWorldResource(String template, String defaultName) { this.template = template; this.defaultName = defaultName; this.counter = new AtomicLong(); } @GET @Timed public Saying sayHello(@QueryParam("name") Optional<String> name) { return new Saying(counter.incrementAndGet(), String.format(template, name.or(defaultName))); } }
Finally, we’re in the thick of it! Let’s start from the top and work our way down.
HelloWorldResource
has two annotations: @Path
and
@Produces
. @Path("/hello-world")
tells Jersey that this
resource is accessible at the URI /hello-world
, and
@Produces(MediaType.APPLICATION_JSON)
lets Jersey’s content negotiation
code know that this resource produces representations which are
application/json
.
HelloWorldResource
takes two parameters for construction: the
template
it uses to produce the saying and the defaultName
used when the user declines to tell us their name. An AtomicLong
provides
us with a cheap, thread-safe way of generating unique(ish) IDs.
Remember: Resource classes are used by multiple threads concurrently. In general, we recommend that resources be stateless/immutable, but it’s important to keep the context in mind.
sayHello(Optional<String>)
is the meat of this class, and it’s a
fairly simple method. The @QueryParam("name")
tells Jersey to map the
name
parameter from the query string to the name
parameter
in the method. If the client sends a request to /hello-world?name=Dougie
,
sayHello
will be called with Optional.of("Dougie")
; if there
is no name
parameter in the query string, sayHello
will be
called with Option.absent()
. (Support for Guava's Optional
is a little extra sauce that Dropwizard adds to Jersey's existing functionality.)
Inside the sayHello
method, we increment the counter, format the template
using String.format(String, Object...)
, and return a new
Saying
instance.
Because sayHello
is annotated with @Timed
, Dropwizard
automatically records the duration and rate of its invocations as a Metrics Timer.
Once sayHello
has returned, Jersey takes the Saying
instance
and looks for a provider class which can write Saying
instances as
application/json
. Dropwizard has one such provider built in which allows
for producing and consuming Java objects as JSON objects. The provider writes out the
JSON and the client receives a 200 OK
response with a content type of
application/json
.
Before that will actually work, though, we need to go back to our
HelloWorldService
and add this new resource class. In its
initialize
method we can read the template and default name from the
HelloWorldConfiguration
instance, create a new
HelloWorldService
instance, and then add it to the service’s environment:
@Override protected void initialize(HelloWorldConfiguration configuration, Environment environment) { final String template = configuration.getTemplate(); final String defaultName = configuration.getDefaultName(); environment.addResource(new HelloWorldResource(template, defaultName)); }
When our service starts, we create a new instance of our resource class with the
parameters from the configuration file and hand it off to the Environment
,
which acts like a registry of all the things your service can do.
Before we go too far, we should add a health check for our service.
Adding A Health Check
Health checks give you a way of adding small tests to your service to allow you and your ops team to verify that your service is functioning correctly in production. We strongly recommend that all of your services have at least a minimal set of health checks. (We recommend this so strongly, in fact, that Dropwizard will nag you should you neglect to add a health check to your project.)
Since formatting strings is not likely to fail while a service is running (unlike, say, a database connection pool), we’ll have to get a little creative here. We’ll add a health check to make sure we can actually format the provided template:
package com.example.helloworld.health; import com.yammer.metrics.core.HealthCheck; public class TemplateHealthCheck extends HealthCheck { private final String template; public TemplateHealthCheck(String template) { super("template"); this.template = template; } @Override protected Result check() throws Exception { final String saying = String.format(template, "TEST"); if (!saying.contains("TEST")) { return Result.unhealthy("template doesn't include a name"); } return Result.healthy(); } }
TemplateHealthCheck
checks for two things: that the provided template is
actually a well-formed format string, and that the template actually produces output
with the given name.
If the string is not a well-formed format string (for example, someone accidentally put
Hello, %s%
in the configuration file), then
String.format(String, Object...)
will throw an
IllegalFormatException
and the health check will implicitly fail. If the
rendered saying doesn’t include the test string, the health check will explicitly fail
by returning an unhealthy Result
.
As with most things in Dropwizard, we create a new instance with the appropriate
parameters and add it to the Environment
:
@Override protected void initialize(HelloWorldConfiguration configuration, Environment environment) { final String template = configuration.getTemplate(); final String defaultName = configuration.getDefaultName(); environment.addResource(new HelloWorldResource(template, defaultName)); environment.addHealthCheck(new TemplateHealthCheck(template)); }
Now we're almost ready to go!
Building Fat JARs
We recommend that you build your Dropwizard services as “fat” JAR files—single
.jar
files which contain all of the .class
files
required to run your service. This allows you to build a single deployable artifact
which you can copy from your staging environment to your QA environment to your
production environment without worrying about differences in installed libraries. To
start building our Hello World service as a fat JAR, we need to configure a Maven plugin
called maven-shade
. In your pom.xml
file, add this:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>1.4</version> <configuration> <createDependencyReducedPom>true</createDependencyReducedPom> </configuration> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>com.example.helloworld.HelloWorldService</mainClass> </transformer> </transformers> </configuration> </execution> </executions> </plugin>
This configures Maven to do a couple of things during its package
phase:
-
Produce a
pom.xml
file which doesn’t include dependencies for the libraries whose contents are included in the fat JAR. -
Collate the various
META-INF/services
entries in the JARs instead of overwriting them. (Jersey doesn’t work without those.) -
Set
com.example.helloworld.HelloWorldService
as the JAR’sMainClass
.
Once you’ve got that configured, go into your project directory and run
mvn package
(or run the package
goal from your IDE). You
should see something like this:
[INFO] Including org.eclipse.jetty:jetty-util:jar:7.6.0.RC0 in the shaded jar. [INFO] Including com.google.guava:guava:jar:10.0.1 in the shaded jar. [INFO] Including com.google.code.findbugs:jsr305:jar:1.3.9 in the shaded jar. [INFO] Including org.hibernate:hibernate-validator:jar:4.2.0.Final in the shaded jar. [INFO] Including javax.validation:validation-api:jar:1.0.0.GA in the shaded jar. [INFO] Including org.yaml:snakeyaml:jar:1.9 in the shaded jar. [INFO] Replacing original artifact with shaded artifact. [INFO] Replacing /Users/yourname/Projects/hello-world/target/hello-world-0.0.1-SNAPSHOT.jar with /Users/yourname/Projects/hello-world/target/hello-world-0.0.1-SNAPSHOT-shaded.jar [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 8.415s [INFO] Finished at: Fri Dec 02 16:26:42 PST 2011 [INFO] Final Memory: 11M/81M [INFO] ------------------------------------------------------------------------
Congratulations! You’ve built your first Dropwizard project! Now it’s time to run it!
Running Your Service
Now that you’ve built a JAR file, it’s time to run it.
In your project directory, run
java -jar target/hello-world-0.0.1-SNAPSHOT.jar
. You should see something
like the following:
java -jar dropwizard-example-0.1.0-SNAPSHOT.jar <command> [arg1 arg2] Commands ======== server: Starts an HTTP server running the service ------------------------------------------------- usage: java -jar dropwizard-example-0.1.0-SNAPSHOT.jar server <config file> -h, --help display usage information
Dropwizard takes the first command line argument and dispatches it to a matching
command. In this case, the only command available is server
, which runs
your service as an HTTP server. The server
command requires a configuration
file, so let’s go ahead and give it
the one we previous saved:
java -jar target/hello-world-0.0.1-SNAPSHOT.jar server hello-world.yml
You should see something like the following:
INFO [2011-12-03 00:38:32,927] com.yammer.dropwizard.cli.ServerCommand: Starting hello-world INFO [2011-12-03 00:38:32,931] org.eclipse.jetty.server.Server: jetty-7.x.y-SNAPSHOT INFO [2011-12-03 00:38:32,936] org.eclipse.jetty.server.handler.ContextHandler: started o.e.j.s.ServletContextHandler{/,null} INFO [2011-12-03 00:38:32,999] com.sun.jersey.server.impl.application.WebApplicationImpl: Initiating Jersey application, version 'Jersey: 1.10 11/02/2011 03:53 PM' INFO [2011-12-03 00:38:33,041] com.yammer.dropwizard.config.Environment: GET /hello-world (com.example.helloworld.resources.HelloWorldResource) INFO [2011-12-03 00:38:33,215] org.eclipse.jetty.server.handler.ContextHandler: started o.e.j.s.ServletContextHandler{/,null} INFO [2011-12-03 00:38:33,235] org.eclipse.jetty.server.AbstractConnector: Started BlockingChannelConnector@<IP_ADDRESS>:8080 STARTING INFO [2011-12-03 00:38:33,238] org.eclipse.jetty.server.AbstractConnector: Started SocketConnector@<IP_ADDRESS>:8081 STARTING
Your Dropwizard service is now listening on ports 8080
for service requests
and 8081
for administration requests. If you press
^C, the service will shut down gracefully, first closing
the server socket, then allowing a few seconds for in-flight requests to be processed,
then shutting down the process itself.
But while it’s up, let’s give it a whirl! Click here to say hello! Click here to get even friendlier!
So, we’re generating sayings. Awesome. But that’s not all your service can do. One of the main reasons for using Dropwizard is the out-of-the-box operational tools it provides, all of which can be found on the admin port.
If you click through to metrics, you can see all of your service’s metrics represented as a JSON object.
The threads resource allows you to quickly get a thread dump of all the threads running in that process.
The healthcheck
resource runs the TemplateHealthCheck
instance we
wrote. You should see something like this:
* deadlocks: OK * template: OK
template
here is the result of your TemplateHealthCheck
, which
unsurprisingly passed. deadlocks
is a built-in health check which looks for
deadlocked JVM threads and prints out a listing if any are found.
Next Steps
Well, congratulations. You’ve got a Hello World service ready for production (except for the lack of tests) that’s capable of doing 15,000-20,000 requests per second. Hopefully you've gotten a feel for how Dropwizard combines Jetty, Jersey, Jackson, and other stable, mature libraries to provide a phenomenal platform for developing RESTful web services.
There’s a lot more to Dropwizard than is covered here (commands, bundles, servlets, advanced configuration, validation, HTTP clients, database clients, templates, etc.), all of which is covered in by Dropwizard's manual.

What?
shitproduct puts the focus back to the creators of your favourite games.
Here, you will see them talk about their creations and about themselves live-action style.
YouTube allows us to bring you closer to your favourite game developer without the hassles of stalking them down yourself.
How?
Simple. By letting the creators upload a video of themselves rambling on the camera, for as long as they want to.
If you know of any game developers living in your area or if you'd like to travel around the world to point webcams at game developers,
by all means. Just make sure it's daylight and speak loud and clear! Creators are encouraged to link to their creations (any format).
The only rule is the games should be at least 10 years old. This helps to reduce drama, scenesterism and spam disguised as self-promotion.
Why?
Because game developers are people too. What do you mean why? Because this should exist!
Shouldn't you know who made them? Wouldn't you like to know what other games they are currently making or have made? And no, EA is not a developer's name.

Breathing Kirigami
The artform of kirigami is a variation of the traditional origami that
allows cuts of the paper, as opposed to only folds. In this project, I intertwined the natural simplicity of kirigami with the electronics of a microcontoller using only fine
thread as an intermediary in order to animate the delicate paper in motions resembling slight breadths.
I first experimented with different forms of kirigami to find a shape most conducive to resembling the pattern of inhalation and
exhalation once animated.
To allow for the breathing motion, I threaded the edges of the kirigami together and then
attached the ends to a motor. This motor was controlled by an Ardunio Uno programmed to simply
provide and release tension cyclically, thus resulting in a breathing motion of the paper folds.

ScalaTest 2.1.3 is a maintenance release for the 2.1.x series that includes five enhancements and a bug fix. No source code using ScalaTest 2.0+ should break, but you will likely need to do a clean build to upgrade from 2.0. However, 2.1.3 is binary compatible with 2.1.0, 2.1.1, and 2.1.2, so you can just change the version number in your build to upgrade from earlier 2.1.x releases.

[Gecode] Documentation still needs completion...

Dear all,
I encourage all of you to check the "class" page of the genereated
documentation for lacking documentation now and then. I think it is a good
idea to have at least a brief sentence about what each class does in
principle
Currently the following areas are still incompletely documented:
int/cumulatives (just a minor omission)
int/sortedness
int/gcc
set/branch (here the structure is still not the structure we agreed upon
for branching as it does not allow for reusing the variable/value selection
classes)
set/* some small random omissions
examples/* some few examples (recent additions still lack doc)

 This module exposes several APIs that allow to manage failing tasks in a convenient way by either replaying a failed task or by replicating a specific task to begin with.
Task replay is analogous to the Checkpoint/Restart mechanism found in conventional execution models. The key difference being localized fault detection. When the runtime detects an error it replays the failing task as opposed to completely rolling back of the entire program to the previous checkpoint.
Task replication is designed to provide reliability enhancements by replicating a set of tasks and evaluating their results to determine a consensus among them. This technique is most effective in situations where there are few tasks in the critical path of the DAG which leaves the system underutilized or where hardware or software failures may result in an incorrect result instead of an error. However, the drawback of this method is the additional computational cost incurred by repeating a task multiple times.
The following API functions are exposed:
hpx::resiliency::async_replay: This version of task replay will catch user defined exceptions and automatically reschedule the task N times before throwing an hpx::resiliency::abort_replay_exception if no task is able to complete execution without an exception.
hpx::resiliency::async_replay_validate: This version of replay adds an argument to async replay which receives a user provided validation function to test the result of the task against. If the task’s output is validated, the result is returned. If the output fails the check or an exception is thrown, the task is replayed until no errors are encountered or the number of specified retries have been exceeded.
hpx::resiliency::async_replicate: This is the most basic implementation of the task replication. The API returns the first result that runs without detecting any errors.
hpx::resiliency::async_replicate_validate: This API additionally takes a validation function which evaluates the return values produced by the threads. The first task to compute a valid result is returned.
hpx::resiliency::async_replicate_vote: This API adds a vote function to the basic replicate function. Many hardware or software failures are silent errors which do not interrupt program flow. In order to detect errors of this kind, it is necessary to run the task several times and compare the values returned by every version of the task. In order to determine which return value is “correct”, the API allow the user to provide a custom consensus function to properly form a consensus. This voting function then returns the “correct”” answer.
hpx::resiliency::async_replicate_vote_validate: This combines the features of the previously discussed replicate set. Replicate vote validate allows a user to provide a validation function to filter results. Additionally, as described in replicate vote, the user can provide a “voting function” which returns the consensus formed by the voting logic.
hpx::resiliency::dataflow_replay: This version of dataflow replay will catch user defined exceptions and automatically reschedules the task N times before throwing an hpx::resiliency::abort_replay_exception if no task is able to complete execution without an exception. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
hpx::resiliency::dataflow_replay_validate : This version of replay adds an argument to dataflow replay which receives a user provided validation function to test the result of the task against. If the task’s output is validated, the result is returned. If the output fails the check or an exception is thrown, the task is replayed until no errors are encountered or the number of specified retries have been exceeded. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
hpx::resiliency::datafloe_replicate: This is the most basic implementation of the task replication. The API returns the first result that runs without detecting any errors. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
hpx::resiliency::datafloe_replicate_validate: This API additionally takes a validation function which evaluates the return values produced by the threads. The first task to compute a valid result is returned. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
hpx::resiliency::datafloe_replicate_vote: This API adds a vote function to the basic replicate function. Many hardware or software failures are silent errorswhich do not interrupt program flow. In order to detect errors of this kind, it is necessary to run the task several times and compare the values returned by every version of the task. In order to determine which return value is “correct”, the API allow the user to provide a custom consensus function to properly form a consensus. This voting function then returns the “correct”” answer. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
hpx::resiliency::datafloe_replicate_vote_validate: This combines the features of the previously discussed replicate set. Replicate vote validate allows a user to provide a validation function to filter results. Additionally, as described in replicate vote, the user can provide a “voting function” which returns the consensus formed by the voting logic. Any arguments for the executed task that are futures will cause the task invocation to be delayed until all of those futures have become ready.
