Koa requires node v7.6.0 or higher for ES2015 and async function support.
You can quickly install a supported version of node with your favorite version manager:
$ nvm install 7
$ npm i koa
$ node my-koa-app.js
To use async
functions in Koa in versions of node < 7.6, we recommend using babel's require hook.
require('babel-register'); // require the rest of the app that needs to be transpiled after the hook const app = require('./app');
To parse and transpile async functions,
you should at a minimum have the transform-async-to-generator
or transform-async-to-module-method plugins.
For example, in your .babelrc
file, you should have:
{ "plugins": ["transform-async-to-generator"] }
You can also use the env preset with a target option "node": "current"
instead.
A Koa application is an object containing an array of middleware functions which are composed and executed in a stack-like manner upon request. Koa is similar to many other middleware systems that you may have encountered such as Ruby's Rack, Connect, and so on - however a key design decision was made to provide high level "sugar" at the otherwise low-level middleware layer. This improves interoperability, robustness, and makes writing middleware much more enjoyable.
This includes methods for common tasks like content-negotiation, cache freshness, proxy support, and redirection among others. Despite supplying a reasonably large number of helpful methods Koa maintains a small footprint, as no middleware are bundled.
The obligatory hello world application:
const Koa = require('koa'); const app = new Koa(); app.use(async ctx => { ctx.body = 'Hello World'; }); app.listen(3000);
Koa middleware cascade in a more traditional way as you may be used to with similar tools - this was previously difficult to make user friendly with node's use of callbacks. However with async functions we can achieve "true" middleware. Contrasting Connect's implementation which simply passes control through series of functions until one returns, Koa invoke "downstream", then control flows back "upstream".
The following example responds with "Hello World", however first the request flows through
the x-response-time
and logging
middleware to mark when the request started, then continue
to yield control through the response middleware. When a middleware invokes next()
the function suspends and passes control to the next middleware defined. After there are no more
middleware to execute downstream, the stack will unwind and each middleware is resumed to perform
its upstream behaviour.
const Koa = require('koa'); const app = new Koa(); // logger app.use(async (ctx, next) => { await next(); const rt = ctx.response.get('X-Response-Time'); console.log(`${ctx.method} ${ctx.url} - ${rt}`); }); // x-response-time app.use(async (ctx, next) => { const start = Date.now(); await next(); const ms = Date.now() - start; ctx.set('X-Response-Time', `${ms}ms`); }); // response app.use(async ctx => { ctx.body = 'Hello World'; }); app.listen(3000);
Application settings are properties on the app
instance, currently
the following are supported:
app.env
defaulting to the NODE_ENV or "development"app.proxy
when true proxy header fields will be trustedapp.subdomainOffset
offset of .subdomains
to ignore [2]A Koa application is not a 1-to-1 representation of an HTTP server. One or more Koa applications may be mounted together to form larger applications with a single HTTP server.
Create and return an HTTP server, passing the given arguments to
Server#listen()
. These arguments are documented on nodejs.org. The following is a useless Koa application bound to port 3000
:
const Koa = require('koa'); const app = new Koa(); app.listen(3000);
The app.listen(...)
method is simply sugar for the following:
const http = require('http'); const Koa = require('koa'); const app = new Koa(); http.createServer(app.callback()).listen(3000);
This means you can spin up the same application as both HTTP and HTTPS or on multiple addresses:
const http = require('http'); const https = require('https'); const Koa = require('koa'); const app = new Koa(); http.createServer(app.callback()).listen(3000); https.createServer(app.callback()).listen(3001);
Return a callback function suitable for the http.createServer()
method to handle a request.
You may also use this callback function to mount your Koa app in a
Connect/Express app.
Add the given middleware function to this application. See Middleware for more information.
Set signed cookie keys.
These are passed to KeyGrip,
however you may also pass your own KeyGrip
instance. For
example the following are acceptable:
app.keys = ['im a newer secret', 'i like turtle']; app.keys = new KeyGrip(['im a newer secret', 'i like turtle'], 'sha256');
These keys may be rotated and are used when signing cookies
with the { signed: true }
option:
ctx.cookies.set('name', 'tobi', { signed: true });
app.context
is the prototype from which ctx
is created.
You may add additional properties to ctx
by editing app.context
.
This is useful for adding properties or methods to ctx
to be used across your entire app,
which may be more performant (no middleware) and/or easier (fewer require()
s)
at the expense of relying more on ctx
, which could be considered an anti-pattern.
For example, to add a reference to your database from ctx
:
app.context.db = db(); app.use(async ctx => { console.log(ctx.db); });
Note:
ctx
are defined using getters, setters, and Object.defineProperty()
. You can only edit these properties (not recommended) by using Object.defineProperty()
on app.context
. See https://github.com/koajs/koa/issues/652.ctx
and settings. Thus, mounted apps are really just groups of middleware.By default outputs all errors to stderr unless app.silent
is true
.
The default error handler also won't output errors when err.status
is 404
or err.expose
is true
.
To perform custom error-handling logic such as centralized logging you can add an "error" event listener:
app.on('error', err => { log.error('server error', err) });
If an error is in the req/res cycle and it is not possible to respond to the client, the Context
instance is also passed:
app.on('error', (err, ctx) => { log.error('server error', err, ctx) });
When an error occurs and it is still possible to respond to the client, aka no data has been written to the socket, Koa will respond appropriately with a 500 "Internal Server Error". In either case an app-level "error" is emitted for logging purposes.


The AutoCorrelation function (ACF) is a plugin made for ImageJ which enable the user to perform autocorrelation calculations in both space and time on an image or a sequence of images. The plugin returns the characteristic time and distance of the images.
The ACF plugin reads an image or sequence of images and uses the pixel values to measure the characteristic autocorrelation times and distances.
These characteristic times and distances can be seen as the average period or distances at which one pixel value will be repeated. They can be used to calculate the typical frequency of a fluctuation or the size of domains on an image.
ACF can also perform the measurement of the autocorrelation in time after doing the Fourier transform of the image. By doing so, the different ranges of spatial frequencies are analysed separately to extract their period of oscillation in time.
The correlation in space, which is an 2-D ACF, can be calculated via two different algorithms:
The time correlation, which is a 1-D ACF, is simply done by multiplying each pixel value Ixy(t) with all the other pixel values Ixy(t+t’).
The whole plugin is free to download. Use the link below to start the download (10MB). The source code can also be obtained from its GitHub page.
Please remember that full support is not provided for this software. You are still free to contact me if you have specific questions on the code, but I cannot guarantee that I will be able to help you.


Gauge Symmetries and Lagrangian
Random notes for Section 14.1 of Halzen & Martin.
Conserved Quantities
Conserved quantities are conserved locally in space, not just globally.
In classical mechanics
- Lagrangian is \begin{equation} L = T-V. \end{equation}
-
Lagrange’s equation
\begin{equation} \frac{d}{dt}\left( \frac{\partial L}{\partial \dot q_i} \right) - \frac{\partial L}{\partial q_i} = 0, \end{equation}
where $q_i$ are the generalized coordinates and $\dot q_i \equiv \frac{d q_i}{dt}$.
To generalize to quantum fields, we generalize the generalized coordinates to fields, so that descretized coordinates $q_i$ becomes fields $\phi(x,t)$.
- Lagrangian density is \begin{equation} \mathcal L (\phi,\partial \phi/\partial x_\mu, x_\mu). \end{equation}
- Lagrangian is \begin{equation} L = \int \mathcal L d^3 x. \end{equation}
- The equation of dynamics is Euler-Lagrangian equation \begin{equation} \frac{\partial }{\partial x_\mu} \left( \frac{ \partial \mathcal L }{ \partial ( \phi_{,\mu} ) } \right) - \frac{\partial \mathcal L}{\partial \phi} = 0, \end{equation} where we denoted $\partial \phi/\partial x_\mu$ as $\phi_{,\mu}$.
By convention, Lagrangian density is usually called Lagrangian in QFT.
- Klein-Gordon equation $(\Box^2 + m^2)\phi = 0$: Lagrangian is $\mathcal L = \frac{1}{2} \partial_\mu \phi \partial^\mu \phi - \frac{1}{2} m^2 \phi^2$.
- Dirac equation: Lagrangian is $\mathcal L = i \bar \psi \gamma_\mu \partial^\mu \psi - m \bar \psi \psi$.
- Maxwell equation $\partial_\mu F^{\mu\nu} = j^\nu$ ($F^{\mu\nu} = \partial^\mu A^\nu - \partial^\nu A^\mu$): Lagrangian is $\mathcal L = - \frac{1}{4} F_{\mu\nu} F^{\mu\nu} - j^\mu A_\mu $.
- Massive photons $(\Box^2 + m^2)A^\mu= j^\mu$: Lagrangian is $\mathcal L = - \frac{1}{4} F_{\mu\nu} F^{\mu\nu} - j^\mu A_\mu + \frac{1}{2}m^2 A_\mu A^\mu$.
One should connect Feynmann rules with Lagrangians.

java.lang.Object | +--org.apache.bcel.util.InstructionFinder
InstructionFinder is a tool to search for given instructions patterns, i.e., match sequences of instructions in an instruction list via regular expressions. This can be used, e.g., in order to implement a peep hole optimizer that looks for code patterns and replaces them with faster equivalents.
This class internally uses the Regexp package to search for regular expressions. A typical application would look like this:
InstructionFinder f = new InstructionFinder(il); String pat = "IfInstruction ICONST_0 GOTO ICONST_1 NOP (IFEQ|IFNE)"; for(Iterator i = f.search(pat, constraint); i.hasNext(); ) { InstructionHandle[] match = (InstructionHandle[])i.next(); ... il.delete(match[1], match[5]); ... }

ENVIRONMENTAL HEALTH MURAL
ARTWORK FOR KETTERING ATRIUM // NIKON D2300, PHOTOSHOP, PENTEL BRUSH PEN
The University of Cincinnati underwent a $5 million renovation project, turning the atrium of the Kettering Laboratory Complex into a beautiful space for students and faculty. The Chair of Environmental Health, Shuk-Mei Ho, PhD, envisioned a collaboration between the Department of Environmental Health and the College of Design, Architecture, Art, and Planning. Six design students were selected to create artwork representing the department's core values.
After visiting New York City over the summer, I captured the detrimental effects gasoline and other elements can have on the environment through a series of photos, combining and overlaying them in Photoshop. I used a Pentel Brush Pen, hand lettering a quote from American writer and environmental activist Sidney Sheldon. When we respect the Earth, the benifits are reciprocated.


Since 2014 we stage daily interventions into Slovenian media space. Our interventions are composed of up to 1000 characters, and they draw attention to the hidden aspects of big stories, they highlight small but significant incidents, and monitor independent media and their backstage. Unsigned.

Israel Folau Is Under Fire After His Latest Controversial Comments
Sacked rugby union star Israel Folau is in hot water after suggesting the NSW bushfire crisis was a “taste of God’s judgment” for legalising same-sex marriage and abortion.
SCROLL DOWN FOR VIDEO
Folau made the comments -- which were streamed online -- during an address at a church in Sydney.
FIVEaa’s Stephen Rowe said on Monday’s FIVEaa Breakfast show:
“I heard you guys bring up Izzy Folau…
“Do we the media have to peddle and perpetuate Izzy’s views? I think 99 per cent of us -- your listeners said it earlier -- we don’t believe what Izzy’s saying and he’s irrelevant.
“He was a sporting star -- he’s not now. He’s a disgraced, sacked sporting star, so I think he’s irrelevant and so too should his views be… he can run his own race. None of us believe him.”

Political parties have to choose their path: Sharad Pawar on government formation in Maharashtra
by PTIHighlights
- Speaking to media in Parliament, Sharad Pawar said, "BJP-Shiv Sena fought together, we (NCP) and Congress fought together in the elections. They have to choose their path and we will do our politics."
- Sharad Pawar will meet Sonia Gandhi today evening to discuss a possible alliance with the Shiv Sena to form a government in Maharashtra.
NEW DELHI: Ahead of his meeting with Congress president Sonia Gandhi, NCP chief Sharad Pawar on Monday said all the political parties seeking to stake claim in forming government in Maharashtra have to "choose their path."
The Sena had reached out to the Congress-NCP combine for support after its alliance with the BJP collapsed.
"BJP-Shiv Sena fought together, we (the NCP) and the Congress fought together. They have to choose their path and we will do our politics," he told reporters before the Winter Session of Parliament began.
The saffron alliance had secured a comfortable majority by winning 105 and 56 seats, respectively, in the 288-member Maharashtra assembly.
Pre-poll allies Congress and NCP won 44 and 54 seats.


Got oily hair problems? These tips might come handy
Oil from the scalp becomes fluid at warmer temperatures and, with sweat, moves further down to make the roots look greasy.
by Lifestyle DeskWhen you wrap yourself to keep warm, you tend to sweat more, making the hair appear oilier than usual. Oil from the scalp becomes fluid at warmer temperatures and, with sweat, move further down to make the roots look greasy.
It can also lead to a dandruff flare-up, since the warmer it is around the scalp, the perfect it is for dandruff-causing microbes to thrive. Washing the hair less also leads to a much oilier scalp. In winters especially, the scalp continuously makes oil, every hour of the day, and without shampoo, excess oil accumulates, and so do the dirt and dust particles.
For oily hair, use these things:
Acai berries: Full of folic acid, zinc, and vitamins A, C, E, and B, acai berries keep your scalp healthy and balanced.
Chamomile: Look to chamomile extract in your products as a gentle, nourishing cleanser that strengthens your hair from within.
Green tea: Another ingredient that works wonders with balancing your hair and scalp’s moisture levels, green tea can reduce sebum production.
Marshmallow root: With its soothing and antibacterial properties, marshmallow root can restore your scalp, while also gently softening your hair.
Keratin and other proteins: If your ends are dry, use a keratin-infused product to strengthen and restore your hair.
Here are some DIY masks that you can make at home for a good-hair day:
Deep conditioning oils for dry hair
1 tbsp – Jojoba oil
1 tbsp – Olive oil
1 tbsp – Shea butter
1/2 tbsp – Amla powder
1/2 tbsp – Bhringraj
1/2 tbsp – Hibiscus flower
2ml – Rosemary essential oil
Method:
*Boil amla powder, bhringraj and hibiscus flowers in a mixture of jojoba and olive oil. Let it cool down a bit and then strain it. Add rosemary essential oil to it and apply on the scalp for about two hours after warming it up a little. Wash your hair with a mild foaming hair cleanser.
Jojoba oil is a natural emollient and hair conditioning agent. Olive oil is a general emollient for the hair and scalp. Use this preparation once a week.
Conditioning lotion for oily lair
Water (enough to boil mulethi)
2 tbsp – Mulethi (liquorice)
1 tbsp – Lemon juice
1 tsp – Honey
10 drops – Tea tree oil
10 drops – Basil oil
Method:
*Boil two tablespoons of mulethi root powder in water for 10 to 15 minutes, over low flame. Cool and filter through a double muslin cloth. Now, mix mulethi decoction, lemon juice, honey and essential oils. Apply on scalp and hair and leave the lotion for 15-30 minutes. Wash the hair with warm water and dry. Use this lotion once a week.
Mulethi, which is believed to have sebum controlling properties, in combination with lemon juice (astringent) has good oil-controlling properties on hair and scalp. Honey is a good moisturizer of hair and scalp.


The protection of privacy, a challenge these days:
What are we doing today to preserve our privacy in this new digital world? We read social networks such as Facebook or Google+ more without moderation.
And we are posting our moods and other stuff without worrying about what will happen to our data, in the near future but also in the more distant future!
Also, it appears that our practices on social networks are security challenges of tomorrow: I invite you to watch this video or a security expert (Mikko Hyppönen at USI – OCTO Technology), explains these issues. Take a few minutes to look at is quite edifying!
There was a time, where all electronic devices did not exist! How we were doing then? We went to the cafe, or in a public place to meet people, our friends, our acquaintances.
Today the situation has completely changed! With the proliferation of electronic
applications on media such as telephone or tablets but also personal computers, without extent, we are
posting our moods if we had a good night, or if we butt itch!
Everything is an artifact to be posted, and we are so happy to share such important things in the whole world!
But in the pre digital age, would we have done that? I think not! Today when we post publicly on Facebook, we ask if we would be willing to go to the village square, and with a megaphone, say we had a bad night for example.
Some facts:
The first thing appears: the Internet of the majors are now building an IT model, whose ultimate goal is to collect
our
data. To shape our person, and thus sell tailored advertising. You think I'm paranoid? So let's look at this a little closer:
Google built "data center" on the planet.
Facebook buys WhatsApp for $ 22 million, with the ultimate goal to correlate your Facebook profile
with a phone
number. Facebook has not purchased the application, they bought the data, that is to say, our
phone number.
Twitter, Facebook Google still without the triumvirate of these practices, but they are not alone!
The statements are the first to hack our private data, all in order to protect us of course.
I think businesses are there to make
money it is their goal. They can not survive without money, and thus repay us our wages. So when she can do so
without pain for us, they do it! All because of the “I Agree syndrome”.
Who takes the time to read the Terms and Conditions applications? Nobody actually somehow you have already paid for
the software, and especially for those that are free. You no longer have a choice!
I think there is no fate, and that alternatives may exist and even should have to exist. So I invite you to join
forces with mine, and be ready for change!
With IT professional for over 15 years, other models may exist. Take for example peer-to-peer
model: a long time ago used to share music film also often hacked!
Why not put it to good use model for our data exchanges on social networks? After all our private data do not
necessarily have to pass on third-party
servers, set up in the cloud, and we don't know where they are! Google Facebook and other know where are our data, we are the involuntary clients of these profiling practices.

PRPC-Plaform Project Guide
This repository contains the rules, code, & schema for the base platform.
- Platform developer documentation
- Projects
- infrastructure
- SDE Deployment (infrastructure/deployment/sde/sde)
ALM Tools Access
Developers new to Pega, please see Using Engineering ALM Tools for gaining access to ALM Tools such as Bitbucket, Jenkins, and Artifactory.
Prerequisites
To run the examples below you need java, git and docker. The prerequisite section of SSOT Local Developer Enablement Training provides some good guidance on getting setup. Also note, the examples use linux, for windows add '.bat', for example 'gradlew.bat'.
For a more comprehensive directory of engineering documents, check out "Pega Engineering Documentation - Start Here".
Launching Pega 7
From sources
You can launch the Pega 7 application from the sources of this project by first launching the docker database and then launching tomcat.
$ ./sync-db
$ ./run-web
After the first step, you will have a database running the latest rules from your workspace. The second step will launch tomcat on port 1080.
See Launching a local Pega Web (Infinity) Node for additional details and options!
What if I want to bring my own database rather than the standard docker db?
You must like pain! All kidding aside, just add -Pprconfig=<full-path-to-prconfig>. For example:
# Sync my special database with rules from git.
$ ./sync-db -Pprconfig=/home/vagrant/special-prconfig.xml
or
# Start the web container using special prconfig.xml.
$ ./run-web -Pprconfig=/home/vagrant/special-prconfig.xml
What if I want to work and develop offline?
For more information about working with --offline
, see offlineDevelopment.md.
Working with the docker database
There are a number of options for working with the local postgres database. See db/README.md for full details. It is worth mentioning here that the options work together with the other facilities like rule syncing and launching tomcat.
For example, to launch a second database with a different container name and database port you would use:
$ ./gradlew db:up -PdbPort=5432 -PjobKey=hotfix
Now, you can launch a tomcat against that database using:
$ ./run-web -PdbPort=5432 -PjobKey=hotfix
Building the full PRPC distribution
Build the full PRPC distribution completely from local source. This is a very long running process.
./build-prpc
You can provide additional options for gradle, for example:
# Skip running test task and use an alternate artifactory URL
./build-prpc -x test -PartifactoryURL=http://meshbinhyd.pega.com:8081/artifactory
DO NOT PASS IN -PdbPort=<port>
AND/OR -PjobKey=<key>
TO THIS COMMAND, IT WILL CAUSE A FAILURE
You can get additional information about the command by running
./build-prpc --help
Building locally generated coreAssembly
To generate a coreAssembly distribution use the following command:
./build-core-assembly
You can provide additional options for gradle, for example:
# Skip running test task and use an alternate artifactory URL
./build-core-assembly -x test -PartifactoryURL=http://meshbinhyd.pega.com:8081/artifactory
Once completed, the resultant coreAssembly distribution will be located at ./infrastructure/distribution/coreAssembly/build/libs/coreAssembly-0.0.1-SNAPSHOT.zip
Running integration tests
Integration tests are now enabled as part of pipeline builds. To enable integration tests of a particular module to be run as part of pipeline PR process, follow the below steps :-
- Create a suite class that would consist of all test classes which need to be run as part of the ReadyToShare validation.
- The class created should start with
ReadyToShare
as pipeline would search for classes starting this name and run all the test suites mentioned in the class. - Make sure that class name should be same as that of the java file which contains this class. Failure to do so would result in compilation failures.
- Sample format and other details can be found here :- https://mesh.pega.com/docs/DOC-134531
To run integration tests dependant on S3 or any other AWS resources
- AWSAccessKey, AWSSecretAccessKey and AWSRegion are being made available in the tests as System properties
- These credentials can be accessed in a test as shown here :
String accessKey = System.getProperty("accessKey")
Running integTests locally
To run integration tests present in all modules,
gradlew integTest
To run integration tests which are run as part of pipeline,
gradlew integTest --tests *ReadyToShare*
To run integration tests particular to a module, for instance
gradlew :platform:kernel:search:integtest
To run integration tests dependant on any AWS resources,
-
Get the temporary credentials as mentioned here : https://mesh.pega.com/docs/DOC-111675
-
Pass the credentials(accessKey, secretAccessKey and the sessionToken) and region(optional) as parameters to access AWS resources in the tests. For example,
gradlew integTest --tests=*ReaadyToShare* -PacccessKey=accessKeyValue -PsecretAccessKey=secretAccessKeyValue -PsessionToken=sessionTokenValue -Pregion=regionValue
To run integration tests that depend on Azure Storage account,
gradlew integTest --tests=*ReaadyToShare* -PazureStorageAccountName=<name> -PazureStorageAccountKey=<key>
azureStorageAccountName
& azureStorageAccountKey
will be accessible from test through system properties
Reach out to Integration teams if you need more information on tests that use Azure Storage account
Running rulesync
The most common operation for rulesync, syncing rules to the database, is coverted by the wrapper shell scripts sync-db
and destroy-and-sync-db
.
- sync-db will attempt to sync the rules from git to your docker db
- destroy-and-sync-db will first destroy your current docker db, launch a fresh db and then perform sync
For details on those scripts, run them with the '--help' option.
For a more comprehensive list of gradle tasks for syncing, see tools/prrulesync/README-gradlecommands.md
Dependency versions & Repos
Library dependencies (CI & PRs will fail in release branches if issues are detected starting in release/8.5)
- You should always use specific versions like
1.0.0
- You should not use -SNAPSHOT versions like
1.0.0-SNAPSHOT
- You should not use changing versions like
1.0+
or+
- You should not use version ranges like
[1.0,)
Repositories (CI & PRs will fail in release branches if issues are detected starting in release/8.5)
- Gradle repositories must come form our internal artifactory
- You should not use maven central, jcenter, or any other maven/ivy repo i nyour gradle scripts
See the verifyDependencies task in the build-info plugin for more details
Other useful tasks
Platform Developer Metrics Collection
By default gradle will collect and report performance/environment metrics for local developer(through the use of the nebula gradle-metrics-plugin).
The metrics being collected include the following:
- Info - Gradle start parameters, system properties, environment variables, and SCM information.
- Project - Project name and version used
- Events - Configuration, dependency resolution, and task execution
- Tasks - List of tasks executed and the time taken by each task.
- Tests - Number of tests executed and elapsed time per test.
- Result - The result of the tasks executed by the user.
The collected metrics are then automatically posted to an Elasticsearch instance located here which is configured in the gradle.properties file.
The metrics can then be viewed using this Kibana instance with pre-configured columns.
To disable this behavior simply set the metricsEnabled
property to false
in the root gradle.properties file.
NOTE: The underyling nebula gradle-metrics-plugin currently outputs a benign stacktrace for a NoSumeMethodError after posting the results, this stack trace will NOT cause a build failure and can be ignored.
Example queries can be found at gradle/docs/gradleBuildMetricsESQueries.md
Code builds
To build the code:
# build code including running unit tests
$ ./gradlew build
# build without running unit tests
$ ./gradlew build -x test
By default we build the core projects. You can build more or less with some additional options. See settings.gradle for full set of options.
-PbuildForPRPC=true Include auxiliary modules such as bix, ResourceKit, that are needed for PRPC Assembly but not earlier; and javadocs, needed for docs but not for coreAssembly
-PbuildTools=false Exclude projects under dev/tools
-PincludeTestProjects=false Exclude test projects
-PbuildAll=true Sets flags to include all the above options in the build. Does not yet include rules.
-PeclipseCompiler=true Use eclipse compiler for building projects, important for hot code replace when using eclipse.
Apply schema
You can apply the latest database schema to your database with this command:
$ ./gradlew applyDDL

public interface Part
Part
interface is the common base interface for
Messages and BodyParts. Part consists of a set of attributes and a "Content".
Attributes:
The Jakarta Mail API defines a set of standard Part attributes that are considered to be common to most existing Mail systems. These attributes have their own settor and gettor methods. Mail systems may support other Part attributes as well, these are represented as name-value pairs where both the name and value are Strings.
Content:
The data type of the "content" is returned by
the getContentType()
method. The MIME typing system
is used to name data types.
The "content" of a Part is available in various formats:
getDataHandler()
method.
The "content" of a Part is also available through a
javax.activation.DataHandler
object. The DataHandler
object allows clients to discover the operations available on the
content, and to instantiate the appropriate component to perform
those operations.
getInputStream()
method.
Any mail-specific encodings are decoded before this stream is returned.
getContent()
method.
This method returns the "content" as a Java object.
The returned object is of course dependent on the content
itself. In particular, a "multipart" Part's content is always a
Multipart or subclass thereof. That is, getContent()
on a
"multipart" type Part will always return a Multipart (or subclass) object.
writeTo()
method that streams
out its bytestream in mail-safe form suitable for transmission.
This bytestream is typically an aggregation of the Part attributes
and its content's bytestream. Message and BodyPart implement the Part interface. Note that in MIME parlance, Part models an Entity (RFC 2045, Section 2.4).

These functions support exporting a GActionGroup on D-Bus. The D-Bus interface that is used is a private implementation detail.
To access an exported GActionGroup remotely, use
g_dbus_action_group_get()
to obtain a GDBusActionGroup.
guint g_dbus_connection_export_action_group (GDBusConnection *connection
,const gchar *object_path
,GActionGroup *action_group
,GError **error
);
Exports action_group
on connection
at object_path
.
The implemented D-Bus API should be considered private. It is subject to change in the future.
A given object path can only have one action group exported on it.
If this constraint is violated, the export will fail and 0 will be
returned (with error
set accordingly).
You can unexport the action group using
g_dbus_connection_unexport_action_group()
with the return value of
this function.
The thread default main context is taken at the time of this call. All incoming action activations and state change requests are reported from this context. Any changes on the action group that cause it to emit signals must also come from this same context. Since incoming action activations and state change requests are rather likely to cause changes on the action group, this effectively limits a given action group to being exported from only one main context.
Since 2.32
void g_dbus_connection_unexport_action_group (GDBusConnection *connection
,guint export_id
);
Reverses the effect of a previous call to
g_dbus_connection_export_action_group()
.
It is an error to call this function with an ID that wasn't returned
from g_dbus_connection_export_action_group()
or to call it with the
same ID more than once.
Since 2.32


Question
Given n points on a 2D plane, find the maximum number of points that lie on the same straight line.
Stats
| Adjusted Difficulty | 5 |
| Time to use | -------- |
Ratings/Color = 1(white) 2(lime) 3(yellow) 4/5(red)
Analysis
This is a difficult coding question.
The idea is simple. For n points, there are n * (n-1) lines. Check slopes and then count total, we would get the answer.
However, coding of this idea is very difficult.
Solution
Firstly, there are 2 special cases when calculating the slope. The 2 points may locate in same position. And when point1.x = point2.x, slope = infinity. It’s easy to omit these 2 cases and result in mistake.
Secondly, when we count, we declare 2 variables: samePointNumber and maxPointCountWithSameSlope. It’s very important to initialize both values to 1 instead of 0! Why? Because these values just can’t be 0. I failed my 2nd version code when input = {(0,0), (0,0)}, the program shows result of 0, instead of 2.
Thirdly, about what data structure to use for counting. There is a discussion about this at here
- storing the vertical slopes as Double.NaN. That allows Double to represent every slope uniquely as (y/x).
- It is unsafe using floating points to make a hash, and -0.0 != 0.0
It’s great that using Double.NaN, it saves us time and effort to count vertical points. Second point is very valid, but it turns out that using HashMap<Double, Integer> can AC.
P.S. It is always not a good practise to use Double as hash key. See here.
Fourthly, I made a mistake here:
double slope = (p.y - q.y) / (p.x - q.x);
And it’s wrong. Why? Note that Point.x and Point.y are both integers. Integer division will return integer. We must cast it.
double slope = (double) (p.y - q.y) / (p.x - q.x);
Last, OMG I wish this is last, but not least, we can reduce execution time to half by checking only the points with larger index than the anchor point (that’s the name for ‘current point’). Good idea, right?
One more thing, how to iterate thru the HashMap (value only)? There is an easy way:
for (Integer a : map.values()) {
a;
}
That’s all I’ve found for now.
Updated on Aug 12th, 2014
Based on the solution given in CC150 v4 Q10.6 on Page 199, it’s a proper way to solve with HashMap<Line, Integer> instead of using HashMap<Double, Integer>.
The reason is mentioned, it’s ‘unsafe using floating points to make a hash’.
Note that if we were to write our own ‘Line’ class, we must override the 2 methods:
- public int hashCode() {}
- public boolean equals(Object o) {}
Code
written by me, Version3 using HashMap
public int maxPoints(Point[] points) {
if (points.length <= 1)
return points.length;
HashMap<Double, Integer> map = null;
int totalMax = 0;
for (Point p : points) {
int samePoint = 1;
map = new HashMap<Double, Integer>();
for (Point q : points) {
if (q == p || p.x > q.x) {
} else if (p.x == q.x && p.y == q.y) {
samePoint++;
} else {
double slope = Double.NaN;
if (p.x != q.x) {
slope = (double) (p.y - q.y) / (p.x - q.x);
}
if (!map.containsKey(slope)) {
map.put(slope, 1);
}
map.put(slope, map.get(slope) + 1);
}
}
int pointMax = 1;
for (Integer a : map.values()) {
pointMax = Math.max(pointMax, a);
}
totalMax = Math.max(totalMax, pointMax + samePoint - 1);
}
return totalMax;
}

Binder Link¶
LinkML - Linked data Modeling Language¶
LinkML is a general purpose modeling language following object-oriented and ontological principles. LinkML models can be specified in YAML, JSON or RDF.
A variety of artefacts can be generated from the model: - ShEx - JSON Schema - OWL - Python dataclasses - UML diagrams - Markdown pages (for deployment in a GitHub pages site)
…and more.
The documentation can also be viewed on the LinkML documentation.
You can browse the metamodel component documentation here. LinkML is self-describing, but a few important vocabulary terms to keep in mind are: - ClassDefinition: Component for defining Classes - SlotDefinition: Component for defining Class Properties (or Slots) - TypeDefinition: Component for defining Data Types - SchemaDefinition: Component for defining Schemas (combination of subset, type, slot, class)
Further details about the general design of LinkML can be found in the LinkML Modeling Language Specification.
As an example, LinkML has been used for the development of the BioLink Model, but the framework itself is general purpose and can be used for any kind of modeling. For an example Biolink metamodel, see this Jupyter Notebook.
Installation¶
This project uses pipenv for installation. Some IDE’s like PyCharm also have direct support for pipenv.
> pipenv install linkml
Language Features¶
Polymorphism/Inheritance, see is_a
Control JSON-LD mappings to URIs via prefix declarations
Ability to refine the meaning of a slot in the context of a particular class via slot usage
Examples¶
LinkML can be used as a modeling language in its own right, or it can be compiled to other schema/modeling languages.
We will use the following simple schema for illustrative purposes:
id: http://example.org/sample/organization
name: organization
types:
yearCount:
base: int
uri: xsd:int
string:
base: str
uri: xsd:string
classes:
organization:
slots:
- id
- name
- has boss
employee:
description: A person
slots:
- id
- first name
- last name
- aliases
- age in years
slot_usage:
last name :
required: true
manager:
description: An employee who manages others
is_a: employee
slots:
- has employees
slots:
id:
description: Unique identifier of a person
identifier: true
name:
description: human readable name
range: string
aliases:
is_a: name
description: An alternative name
multivalued: true
first name:
is_a: name
description: The first name of a person
last name:
is_a: name
description: The last name of a person
age in years:
description: The age of a person if living or age of death if not
range: yearCount
has employees:
range: employee
multivalued: true
inlined: true
has boss:
range: manager
inlined: true
Note that this schema does not illustrate the more advanced datamodel features like in Biolink Model.
Generators¶
JSON Schema is a schema language for JSON documents.
With the example organization
LinkML
schema
schema, we can illustrate the autogeneration of a JSON Schema
output.
You can run:
pipenv run gen-json-schema examples/organization.yaml
Note that any JSON that conforms to the derived JSON Schema can be converted to RDF using the derived JSON-LD context.
JSON-LD context provides mapping from JSON to RDF.
With the example organization
LinkML
schema schema, we can illustrate the
autogeneration of a JSON-LD context
output. You can run:
pipenv run gen-jsonld-context examples/organization.yaml
You can control the output via prefixes declarations and default_curi_maps.
Any JSON that conforms to the derived JSON Schema (see above) can be converted to RDF using this context.
You can also combine a JSON instance file with a JSON-LD context using simple code or a tool like jq:
jq -s '.[0] * .[1]' examples/organization-data.json examples/organization.context.jsonld > examples/organization-data.jsonld
The above generated JSON-LD file can be converted to other RDF serialization formats such as N-Triples. For example we can use Apache Jena as follows:
riot examples/organization-data.jsonld > examples/organization-data.nt
With the example organization
LinkML
schema schema, we can illustrate the
autogeneration of a Python Dataclass
output. You can run:
pipenv run gen-py-classes examples/organization.yaml > examples/organization.py
Python Dataclass for organization
schema
@dataclass
class Organization(YAMLRoot):
_inherited_slots: ClassVar[List[str]] = []
class_class_uri: ClassVar[URIRef] = URIRef("http://example.org/sample/organization/Organization")
class_class_curie: ClassVar[str] = None
class_name: ClassVar[str] = "organization"
class_model_uri: ClassVar[URIRef] = URIRef("http://example.org/sample/organization/Organization")
id: Union[str, OrganizationId]
name: Optional[str] = None
has_boss: Optional[Union[dict, "Manager"]] = None
def __post_init__(self, **kwargs: Dict[str, Any]):
if self.id is None:
raise ValueError(f"id must be supplied")
if not isinstance(self.id, OrganizationId):
self.id = OrganizationId(self.id)
if self.has_boss is not None and not isinstance(self.has_boss, Manager):
self.has_boss = Manager(self.has_boss)
super().__post_init__(**kwargs)
For more details see PythonGenNotes.
The python object can be directly serialized as RDF.
ShEx, short for Shape Expressions Language is a modeling language for RDF files.
With the example organization
LinkML
schema schema, we can illustrate the
autogeneration of a ShEx output. You
can run:
pipenv run gen-shex examples/organization.yaml > examples/organization.shex
ShEx output for organization
schema
BASE <http://example.org/sample/organization/>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

}
Web Ontology Language OWL is modeling language used to author ontologies.
With the example organization
LinkML
schema schema, we can illustrate the
autogeneration of a ShEx output. You
can run:
pipenv run gen-owl examples/organization.yaml > examples/organization.owl.ttl
OWL output for organization
schema
<http://example.org/sample/organization/Organization> a owl:Class,
meta:ClassDefinition ;
rdfs:label "organization" ;
rdfs:subClassOf [ a owl:Restriction ;
owl:onClass <http://example.org/sample/organization/String> ;
owl:onProperty <http://example.org/sample/organization/id> ;
owl:qualifiedCardinality 1 ],
[ a owl:Restriction ;
owl:maxQualifiedCardinality 1 ;
owl:onClass <http://example.org/sample/organization/String> ;

[ a owl:Restriction ;
owl:maxQualifiedCardinality 1 ;
owl:onClass <http://example.org/sample/organization/Manager> ;
owl:onProperty <http://example.org/sample/organization/has_boss> ] .
Generating Markdown documentation¶
The below command will generate a Markdown document for every class and slot in the model which can be used in a static site for ex., GitHub pages.
pipenv run gen-markdown examples/organization.yaml -d examples/organization-docs/
Specification¶
See specification. Also see the semantics folder for an experimental specification in terms of FOL.
FAQ¶
Why invent our own yaml and not use JSON-Schema, SQL, UML, ProtoBuf, OWL, etc.?
Each of these is tied to a particular formalism. JSON Schema to trees. OWL to open world logic. There are various impedance mismatches in converting between these. The goal was to develop something simple and more general that is not tied to any one serialization format or set of assumptions.
There are other projects with similar goals for ex., schema_salad. It may be possible to align with these.
Here X may be bioschemas, some upper ontology (BioTop), UMLS metathesaurus, bio*, and various other attempts to model all of biology in an object model.
Currently, as far as we know there is no existing reference datamodel that is flexible enough to be used here.

Developers Notes¶
A Github action is set up to automatically release the package to PyPI. When it is ready for a new release, create a Github release. The version should be in the vX.X.X format following the semantic versioning specification.
After the release is created, the GitHub action will be triggered to publish to Pypi. The release version will be used to create the Pypi package.
If the Pypi release failed, make fixes, delete the GitHub release, and recreate a release with the same version again.

3.2 Scatter plots (ggplot2)
Now let’s try to recreate our lattice-based achievements using ggplot2.
ggplot2 is radically different from the way that lattice works. lattice is much closer to the traditional way of plotting in R. There are different functions for different types of plots. In ggplot2 this is different. Every plot we want to draw is, at a fundamental level, created in exactly the same way. What differs are the subsequent calls on how to represent the individual plot components (basically x
and y
). This means a much more consistent way of building visualizations, but it also means that things are rather different from what you might have learned about syntax and structure of (plotting) objects in R. But don’t worry, even Tim managed to understand how things are done in ggplot2 (and prior to writing this he had almost never used it before).
Before we get carried away too much, let’s jump right into our first plot using ggplot2.
scatter_ggplot <- ggplot(aes(x = carat, y = price), data = diamonds)
g_sc <- scatter_ggplot + geom_point()
print(g_sc)
Similar to lattice, plots are (usually) stored in objects. But that is about all the similarity there is.
Let’s look at the above code in a little more detail. The first line is the fundamental definition of what we want to plot. We provide the ‘aesthetics’ for the plot via aes()
. We state that we want the values on the x-axis to represent carat and the y-values are price. Furthermore, we want to take these variables from the diamonds
data set. That’s basically it, and this will not change a hell of a lot in the subsequent plotting routines.
What will change in the plotting code chunks that follow is how we want the relationship between these variables to be represented in our plot. This is done by defining so-called ‘geometries’ (geom_...()
). In this first case, we stated that we want the relationship between x
and y
to be represented as points, hence we used geom_point()
.
If we wanted to provide a plot showing the relationship between price and carat in panels representing the quality of the diamonds, we need what in ggplot2 is called ‘faceting’ (i.e. panels in lattice). To achieve this, we simply repeat our plotting call from earlier and add another layer to the call which does the faceting.
g_sc <- scatter_ggplot +
geom_point() +
facet_wrap(~ cut)
print(g_sc)
By default, all plots created by ggplot()
have a grey background. This comes in particularly handy as soon as colors are involved because it increases the contrast of the colors. However, quite some people tend to dislike the grey default theme when aiming to create a simple black-and-white scatter plot, just like in our case. Here, a white facet background seems more suitable, and luckily, ggplot2 lets us easily change the background color using a pre-defined theme called theme_bw()
(make sure to check out ?theme_bw
for a full list of available themes).
g_sc <- scatter_ggplot +
geom_point() +
facet_wrap(~ cut) +
theme_bw()
print(g_sc)
In case you wanted to remove the horizontal and vertical grid lines as well, and hence, end up with a plain white background, an additional line + theme(panel.grid = element_blank())
would be required. For our purposes, however, the above plot version drawing a white instead of a grey background is totally sufficient.
In order to provide the regression line for each panel like we did in lattice, we need a function called stat_smooth()
. This is fundamentally the same function that we used earlier, as the panel.smoother()
in lattice is based on stat_smooth()
.
Putting this together we could do something like this (note that we also change the number of rows and columns into which the facets should be arranged):
g_sc <- scatter_ggplot +
geom_point(color = "grey60") +
facet_wrap(~ cut, nrow = 2, ncol = 3) +
stat_smooth(method = "lm", se = TRUE,
fill = "black", color = "black") +
theme_bw()
print(g_sc)
Simple and straightforward, and the result looks rather similar to the lattice version we created earlier.
Creating a point density scatter plot in ggplot2 is actually a fair bit easier than in lattice, as ggplot2 provides several predefined stat_*()
functions. One of these is designed to create 2-dimensional kernel density estimations, just what we want. However, this is where the syntax of ggplot2 really becomes a bit abstract. The definition of the fill argument of this call is ..density..
which, at least at first glance, does not seem very intuitive.
Furthermore, it is not quite sufficient to supply the stat_*()
function, we also need to state how to map the colors to that definition. Therefore, we need yet another layer which defines what color palette to use. As we want a continuous variable (density) to be filled with a gradient of n colors, we need to use scale_fill_gradientn()
in which we can define the colors we want to be used.
g_sc <- scatter_ggplot +
geom_tile() +
facet_wrap(~ cut, nrow = 3, ncol = 2) +
stat_density2d(aes(fill = ..density..), n = 100,
geom = "tile", contour = FALSE) +
scale_fill_gradientn(colors = c("white",
rev(clrs_hcl(100)))) +
stat_smooth(method = "lm", se = FALSE, color = "black") +
coord_fixed(ratio = 5/30000) +
theme_bw()
print(g_sc)


The Chase inevitably leads into a multi-story building. The chase-ee ducks into an elevator, and the chaser arrives Just in Time for the doors to close in on his or her face. As their quarry rides up to the top in relative comfort, the pursuer is forced to wait for the next elevator or, more likely, take the stairs. Regardless of which route they take, it's still somehow possible for the chaser to arrive at the same floor just seconds after their quarry (It isn't that hard to climb stairs faster than the typical elevator ascends, though if the building is tall enough, stamina will become an issue eventually - elevators don't tire). This can also be used in a race against time.
Can lead to an Empty Elevator moment when the pursuer sets up an ambush at the assumed exit point... and then the doors open to an empty carriage.
Compare to Elevator Escape which draws all its suspense potential from the moment the pursuer heads for the closing elevator door and is eventually blocked off. If he actually manages to get in, expect an Elevator Action Sequence to unfold.
Examples
- In Phantom Quest Corp., Karino manages to keep up with the hospital's elevator by running up the stairs for at least four floors.
- The Second Elevator variant is used in True Lies.
- Justified in Schwarzenegger's film Commando when he jumps on top of the elevator car the chase-ee is taking.
- Played straight in The Rock. Sean Connery takes a lift down six or seven storeys, Nicholas Cage takes the stairs. Resulting increase in lead = 0.
- In Adventures in Babysitting a girl is being chased by two car thieves because she has information that they needed for their next job, she ducks into the elevator, and the door closes on the thieves, forcing them to wait for the elevator to come back down, later the babysitter and her friends take the elevator and retrieve her...
- Happens twice at the end of Midnight Madness:
- Adam gets into one express elevator and it closes just before Harold can get there, forcing harold to take the other one...
- Again, Adam gets to the elevator to the guest rooms before Harold can get there, and Harold takes the stairs, but not before he shuts off all the elevators.
- In Entrapment, when Gin and Mac are fleeing from their theft on the 86th floor, they descend in the elevator. When the security chief realises this, he orders the elevator to be shut down. However, they escape by forcing the doors open.
Security chief: All right Mr Kruz, your friends are rats in a trap.
- In The Grudge, Susan flees Kayako into an elevator and appears to be safe. That is until Toshio is seen on the passing floor, and the next, and the next, and so on and so forth... getting closer with each passing floor.
- In The Man from U.N.C.L.E. (2015), Victoria and the agents race back to the plaza hotel to preserve their cover stories, Solo and Kuryakin run up a lengthy flight of stairs. Victoria simply takes the elevator.
- In an episode of Due South, a man Fraser and Ray Kowalski are chasing who is Ray Vecchio, still undercoverdodges into an elevator. Ray tosses Fraser his cell phone, and while Fraser races up the stairs, Ray calls from a payphone to tell him which floor the elevator stops on.
- Buffy the Vampire Slayer. In "Intervention", Spike forces open the doors to the elevator shaft and drops onto a descending elevator to escape Glory's minions. However they're able to get to the ground floor to cut him off by the time the slow-moving elevator gets there, as they're going down the stairs.
- In Mirror's Edge, this happens while you're chasing Jacknife, resulting in you having to take the other elevator.
- Happens to your opponents a couple of times, too, with Faith getting the elevator closed just as a hail of bullets strike the doors.

MCI Services
The most popular method of residential construction in North America is wood-framed construction. Typical construction steps for a single-family or small multi-family house are:
Sustainability during the construction phase is one of the aspects of “green building," defined by the United States Environmental Protection Agency (EPA) as "the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction."
In this arrangement the client plays an active role in the procurement system by entering into separate contracts with the designer (architect or engineer), the construction manager, and individual trade contractors. The client takes on the contractual role, while the construction or project manager provides the active role of managing the separate trade contracts, and ensuring that they complete all work smoothly and effectively together.
