# PyGreen
A micro web framework/static web site generator.
PyGreen is a simple tool to generate small web sites. The concept is to put all files to serve in a folder and invoke
the [Mako](http://www.makotemplates.org/) template engine on all .html files. The result is quite similar to a classic
PHP application, but with the good features of the Mako templates (like inheritance) and the cool syntax of Python.
PyGreen uses the MIT license.
## Quick Start
To install:
sudo easy_install pygreen
To launch and serve files:
pygreen serve
The above command will serve the files located in the current folder. All files with the .html extension will also be
processed by Mako. So if the current folder contains a file index.html with the following code:
Hello, my age is ${30 - 2}.
When going to http://localhost:8080, you will see:
Hello, my age is 28.
PyGreen can also export all the files of you current folder after having the .html files processed by Mako. To do so,
type this command:
pygreen gen
This can be useful to post your files on Github Pages or any other free static files hosting services.
## Features
PyGreen was designed to *not* have a lot of features. Mako templates can contain Python code, so you can always code
anything you need. The following features are still useful in most projects and are directly integrated in PyGreen.
### Non-generated files
All files with the .mako or .py extension will not be outputed by pygreen gen. This is useful to avoid generating macros
files or templates to inherit. Hidden files (files beginning with '.') will not be generated either.
### Markdown
While it is easy to define your own macro for markdown, it's still a recurrent need for most sites. So there is a
default Mako filter for that:

## FAQ
### I miss feature XYZ, can you add it?
No. But you can. Easily. PyGreen can be a command line application or it can be a small framework to ease creation of
complete Python web applications. PyGreen is just [Mako](http://www.makotemplates.org/) templates served using the
[Flask](http://flask.pocoo.org/) web framework ([Bottle](http://bottlepy.org/) in version 1.x). You can easily modify
any of these using some python code. Example:
from pygreen import pygreen
pygreen.app # the Flask wsgi application, use the @route() decorator to add new routes
pygreen.templates # the Mako TemplateLookup object, do what you want with it
pygreen.cli() # call the command line interface of PyGreen, you can use it or
# just launch a web server using the Flask application object
It's important to understand that PyGreen is just a helper that allows to make simple things simple (like defining 3
html files that inherit from a common template without the need to type code) but doesn't restrict you. You need
anything complex? Mako templates can contain Python code so import whatever you need and use the features it provides.
If you need anything more complex hack through PyGreen and do it. Read the PyGreen code, it's 100 lines with some
documentation, anyone can understand it. If you read this you should be a Python programmer, so just type the code and
get the job done.
### Why is it so cool?
PyGreen was primarily created to be a static web site generator more effective than existing ones. The problem of
existing site generators like Jekyll or Hyde is that they have a fixed number of features. Even if their creators try to
add advanced features those will not be correctly documented, so the users do not know how to use them.
The fact that PyGreen has a small set of features **is a feature**. You don't need to spend hours to read crappy
documentation before discovering it's impossible to do what you want. If you need to do anything which is not trivial
you know you will have to code it, so just do it. That's what I call being pragmatic.
### Does PyGreen need contributions?
Yes! Report issues, write examples in the wiki, propose improvements,
[everything is on Github](https://github.com/nicolas-van/pygreen). Just keep in mind that PyGreen is designed to be
minimalist, so big features will probably not be accepted.
You can also write articles or blog posts about PyGreen.

-webkit-marquee-increment
Defines the distance the marquee moves in each increment.
-webkit-marquee-increment: large | medium | small | <distance>;
The marquee moves a large amount in each increment.
The marquee moves a medium amount in each increment.
The marquee moves a small amount in each increment.
Number as a percentage, length unit.


ColumnDef
ui.grid.grouping
ColumnDef for grouping feature, these are available to be set using the ui-grid gridOptions.columnDefs
Enable grouping on this column
Defaults to true.
Set the grouping for a column. Format is:
{
groupPriority: <number, starts at 0, if less than 0 or undefined then we're aggregating in this column>
}
Note that aggregation used to be included in grouping, but is now separately set on the column via treeAggregation setting in treeBase
We group in the priority order given, this will also put these columns to the high order of the sort irrespective of the sort priority given them. If there is no sort defined then we sort ascending, if there is a sort defined then we use that sort.
If the groupPriority is undefined or less than 0, then we expect to be aggregating, and we look at the aggregation types to determine what sort of aggregation we can do. Values are in the constants file, but include SUM, COUNT, MAX, MIN
groupPriorities should generally be sequential, if they're not then the next time getGrouping is called
we'll renumber them to be sequential.
Defaults to undefined.

MOD.core Class
src/core.js:896
The Application Framework Core
This layer is the actual core of the framework. It contains all utitity functions such as dom functions, and assistive functions such as array checks, mapping, and any other functions that are used to assist in faster development of JS. It is the only layer that can communicate with the Base layer, and it is only accessed by the Sandbox layer.
- This layer is responsible for communication with the Base layer
- All business logic is executed here
- Returns an object with the necessary functions for handling modules
No core method should ever be called from a module, core methods should only be called from the MOD.app object for initialization and the MOD.sandbox object for business logic
Item Index
Methods
create_module
-
moduleID
-
creator
this is a factory function used to create modules for the application
MOD.core.create_module( 'my-module', function( sb ) {
var ret, btn, input, term;
ret = {
init : function () {
btn = sb.find( '.my-btn' )[0] // get the element from the return object
input = sb.find( '.my-input' )[0] // same for the input
sb.add_event( btn, 'click', this.doSomething );
},
destroy : function () {
// handle breaking the module down
sb.remove_event( btn, 'click', ret.doSomething );
btn = input = term = null;
},
doSomething : function () {
// all functionality goes in to functions that are isolated to the module
term = input.value;
sb.notify({
type : 'search-initiated',

});
}
};
returnt ret;
});
Parameters:
Returns:
returns true if module is successfully created, else false

'some-event' : function ( data ) {
// do something with passed in event data
},
'some-other-event' : function ( data ) {
// handle a different event
}
};

Package Namespaces¶
Cloudmesh uses the python package name space feature to allow the definition of plugins to cloudmesh in different packages maintained in different files and directories.
This is an important feature as it allows us to have contributions developed for cloudmesh by different developers.
At thsi time we support the namespace cloudmesh and any module developed with the cloudmesh command generator can be installed into this namespace. The command generator simple creates a template for a plugin with the needed setup, requirements file and code template to be aple to be installed with pip.
You create a new plugin with
`bash
mkdir cloudmesh-mycommand
cd cloudmesh-mycommand
cms sys command generate mycommand .
`
Notice the dot at the end. This will generate than a directory such as
`
cloudmesh-mycommand
├── LICENSE
├── Makefile
├── README.md
├── VERSION
├── cloudmesh
│ ├── __init__.py
│ └── mycommand
│ ├── __init__.py
│ ├── __version__.py
│ ├── api
│ │ ├── __init__.py
│ │ └── manager.py
│ └── command
│ ├── __init__.py
│ └── mycommand.py
├── requirements-dev.txt
├── requirements.txt
├── setup.cfg
└── setup.py
`
Important is that is includes a file cloudmesh/command/mycommand.py which you can modify and use to create your own mycommand plugin.
However, mycommand must not be a previous cloudmesh command which you can find out by usung the cms help function and communicate with Gregor von Laszewski to verify that the command is not already taken.
How to create and design commands are discussed in the cmd5 manual pages. When you look atthe generated command you will see it is very simple.

Import and Setup
Q: Why Eclipse has an error related to the "@Override" annotation ?
A: Please set the compiler level 1.6+ in pom.xml
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>

</build>
Q: What JDK has you tested Parallec with ?
A: We tested it with JDK 6 7 8.
Usage
Q: How to view logs ?
A: Yes.
- Parallec Log: we use slf4j + logback with rotation. Location is in "parallec_logs"
- ParallelTask result log: can be turned on with ParallelTaskBuilder.setAutoSaveLogToLocal(), by default this is turned off.
Q: Do you support retries ?
A:
- Async Http Client supports retry with config.
- From our experience, retrying on a ParallelTask is insufficient as 1% of the failed hosts will keep on retrying, slowing the whole task down. The right way would be 1 time try on all host, then collect those failed one, and then try again on these failed ones.
Q: Do you have plans to update the versions of Async Http Client?
A: We have not been able to use AHC version 1.9.x due to an issue with client auth. Last year with some performance testing, we found more CPU usage and less speed after upgrade from AHC 1.65 to AHC 1.8.14 . We need to do more performance testing before the upgrade.
Updated 09/2016:
Parallec with async-http-client 2.x The version with more up-to-date async-http-client
(currently using AHC version 2.0.15
) is 0.20.0-SNAPSHOT
. This version has passed comprehensive unit tests but has not been used yet in production. This version requires JDK8 due to AHC 2.x and can be used with the parallec-plugins with the same version 0.20.0-SNAPSHOT
, details please check #37.
Q: The logs are too chatty/verbose, can I disable or reduce them?
A: Please refer to the configuration section on "Reduce Verbose Logs"
Q: The task ends prematurely around 10 minutes with response count less than original?
A: Please refer to the configurations section on "Long Running Jobs"
Future Work
Extension to Other Protocols
With the framework and design, Expanding to other new protocols are fairly simple, with changes mostly to add a worker for this new protocol.
- Add support for HTTP/2 or gPRC if needed.
- Add support for SNMP protocols for network devices.
- Evaluate more performant implementations than JSch for SSH.


Angélique Kidjo Singer-songwriter
Angélique Kidjo, (born July 14, 1960, Ouidah, Dahomey [now Benin]), Beninese popular singer known for her collaborations with internationally prominent popular musicians and for her innovative blending of diverse musical styles. Kidjo was born into a family of performing artists. Her father was a musician, and her mother worked as a choreographer and theatre director. At age six Kidjo began performing in her mother’s theatre troupe, and, as a teenager, she sang with her brothers in their rock–rhythm-and-blues band. By age 20 she was a professional singer. She recorded her first album, Pretty, in 1988. In 1983 Kidjo moved to Paris, where she encountered a vibrant musical community and myriad musical styles with which to experiment; in Paris she also met Jean Hebrail, the French producer, composer, and bassist whom she later married. Her first years in the city were spent studying jazz and performing with various local groups. After teaming with the Dutch pianist Jasper van ’t Hof, she sang with and cowrote songs for his jazz group, Pili-Pili. After several years Kidjo left Pili-Pili and recorded Logozo (1991), which featured the American jazz musician Branford Marsalis and the African artists Manu Dibango and Ray Lema. With songs addressing issues of global concern—such as homelessness, the environment, freedom, and integration—Logozo was an international success. Kidjo increased her international appeal through her later releases, including Fifa (1995), in which she and more than 100 other musicians performed songs in English, Fon (her native language), Yoruba, and French.
Kidjo’s subsequent albums
Like her earlier releases, Kidjo’s subsequent albums were exercises in musical fusion, melding an array of genres, including jazz, hip-hop, zouk, Zairean rumba, samba, salsa, funk, gospel, Cameroonian makossa, and various Beninese traditions. Her sixth solo album, Black Ivory Soul (2002), was a dazzling excursion into Brazilian musical forms that deftly blended a Latin sound sensibility with traces of traditional West African rhythms. Oyaya! (2004) included a collaboration with American musician Dave Matthews, and Djin Djin (2007) featured numerous luminaries from the international popular music scene, including Peter Gabriel, Josh Groban, Carlos Santana, and others. Õÿö (2010) was an album of covers, and Spirit Rising (2012) was a collection of live tracks. Eve (2014), a tribute to African women largely sung in Beninese languages, won a Grammy Award for best world music album, as did Sings (2015), a collaboration with the Philharmonic Orchestra of Luxembourg. In 2018 Kidjo covered the Talking Heads album Remain in Light (1980), and the following year she paid homage to Cuban American singer Celia Cruz with Celia.
Kidjo was an outspoken advocate of education and health care for women
In addition to her recording career, Kidjo was an outspoken advocate of education and health care for women and children. In 2002 UNICEF (United Nations Children’s Fund) named her one of its goodwill ambassadors. She was elected one of four vice presidents of the International Confederation of Societies of Authors and Composers (Confederation Internationale des Sociétés d’Auteurs et Compositeurs; CISAC) in 2013. Kidjo also released a memoir, Spirit Rising: My Life, My Music (2014).

The CSS Plugin extends the KUTE.js core engine and enables animation for additional CSS properties as mentioned in the examples page. The focus is on box model properties like padding
, margin
or borderWidth
, as well as other types of properties like borderRadius
, borderColor
, backgroundPosition
, borderColor
or clip
.
In the example below we are doing some animation on the border-radius
property. The first box animates all corners, while the other boxes animate each corner at a time. A quick reminder, for radius properties KUTE.js supports
px
, %
and text properties' units such as em
or rem
.
KUTE.to('selector1',{borderRadius:'100%'}).start();
KUTE.to('selector2',{borderTopLeftRadius:'100%'}).start();
KUTE.to('selector3',{borderTopRightRadius:'100%'}).start();
KUTE.to('selector4',{borderBottomLeftRadius:'100%'}).start();
KUTE.to('selector5',{borderBottomRightRadius:'100%'}).start();
And here is how it looks like:
A quick important reminder here is that KUTE.js does not support shorthands for radius properties. Also early implementations by Mozilla's Firefox browser like -moz-border-radius-topleft
are not supported because they were depracated
with later versions. Download this example here.
The CSS Plugin allows KUTE.js to support almost all the box model properties, but for our example here we will focus mostly on margin and padding, as other properties such as outlineWidth
, minWidth
or maxHeight
require a more complex context and we won't insist on them.
var tween1 = KUTE.to('selector1',{marginTop:200});
var tween2 = KUTE.to('selector1',{marginBottom:50});
var tween3 = KUTE.to('selector1',{padding:30});
var tween4 = KUTE.to('selector1',{margin:'5%'});
We're gonna chain these tweens and start the animation. You can download this example here.
TIP: the width
and height
properties used together can be great for scale
animation fallback on images for legacy browsers.
OK here we're gonna do a cool example for text properties. Basically the below code would work:
var tween1 = KUTE.to('selector1',{fontSize:'200%'});
var tween2 = KUTE.to('selector1',{lineHeight:24});
var tween3 = KUTE.to('selector1',{letterSpacing:50});
var tween3 = KUTE.to('selector1',{wordSpacing:50});
But our example will feature some more than just that. We're gonna animate each character of a given string, with a small delay. The heading will animate fontSize
and letterSpacing
properties for each character while
the button will animate fontSize
and lineHeight
properties. Watch this:
TIP: this should also work in Internet Explorer 8 as a fallback for scale animation for text. The above example uses some CSS hacks to enable opacity animation on IE8, so make sure to check assets/css/css.css
file for more. This
example is not perfect, as legacy browsers don't support the excellent transform functions with subpixel animations, but if it's a must, this would do. Download this example here.
The next example is about animating all border color properties, since the core engine already supports text color
and backgroundColor
properties. So check these lines for reference.
KUTE.to('selector1',{borderColor:'rgb(25,25,25)'}).start();
KUTE.to('selector1',{borderTopColor:'#069'}).start();
KUTE.to('selector1',{borderRightColor:'rgba(25,25,25,0.25)'}).start();
KUTE.to('selector1',{borderBottomColor:'red'}).start(); // IE9+ browsers
KUTE.to('selector1',{borderLeftColor:'#069'}).start();
KUTE.to('selector1',{outlineColor:'#069'}).start();
Let's get some animation going. Download the example here.
A quick reminder: you can also use RGB
or RGBA
, but the last one is not supported on IE8 and it will fallback to RGB
.
This property allows you to animate the rectangular shape of an element that is set to position:absolute
. In CSS this property works like this clip: rect(top,right,bottom,left)
forming a rectangular shape that masks an element making parts of it invisible. While the clip
property have been deprecated, it can still be used to emulate a scale animation for legacy browsers in certain cases.
KUTE.to('selector',{clip:[0,150,100,0]}).start();
A quick example here could look like this:
Note that this would produce no effect for elements that have overflow:visible
style rule. Download this example here.
Another property we can animate with KUTE.js is backgroundPosition
. Quick example:
KUTE.to('selector1',{backgroundPosition:[0,50]}).start();
A working example would look like this:

During my work at a local nonprofit, we did a lot of education on local campaign and issues, held forums and panel talks. Currently I am volunteering for a Pueblo West Fire sales tax, and I've done some calling and texting for that and a local Colorado Springs school district and TABOR ballot issue.
Council of Neighbors and Organizations (CONO), Organization of Westside Neighbors (OWN), Old Colorado City Partnership, Commission on Aging, The Success Collective, City of Colorado Springs Brand Activation Team, City of Colorado Springs Public Engagement Team, El Paso County Community Outreach Group
While serving on the Organization of Westside Neighbors (OWN) Board for the past 2 years, I implemented a first-annual strategic planning session, partnered with 3 organizations for a first-time grant to activate spaces, held community input meetings, executed monthly bike rides, basketball court paint parties, park and trail activation opportunities, communications channels and more. With this hands-on role I have applied my knowledge from CONO to pilot projects in my own neighborhood. Because of this momentum, OWN, partnering with other westside entities, is receiving larger grant funding to assist with merging efforts, business improvement district funding, and LART funding to assist with activation of pop- up street events to help create habits in an otherwise dark and under-utilized area. With OCCP we work with other Colorado business districts, learning and implementing things to support businesses and learn to create our own BID to help the community.
I would like to serve on the commission because I believe in public process and I also think I would bring a good perspective. With my extension background in neighborhood and grassroots organizing, I have an on-the-ground view of how neighborhoods and communities may look and the importance of districting. I would like to learn more about how this process works but I'd also like to be an advocate and help bring input and feedback about this process to the community where I live.
Because of my experience working for a nonprofit who contracted with local municipalities, I have had a lot of time working as the neutral middle party trying to help educate, and communicate facts vs opinions. I also believe in democracy and trained neighborhood boards on how to build consensus and have solution-based conversations. I believe in all voices being heard and coming to an agreement for the betterment of the whole. Better together!
I work with several neighborhood organizations, HOA's, government officials, committees, community members, boards and more. Because of my ability to speak to and work with a diverse audience, I understand the importance of prioritizing, offering solutions, breaking down cause and effect and determining impact.

Falcons’ Freeman moves closer to return from knee injury
FLOWERY BRANCH, Ga. (AP) - Atlanta Falcons running back Devonta Freeman, who has missed two games with a sprained knee, is returning to practice.
Coach Dan Quinn says Freeman will participate in Monday’s light practice as the Falcons prepare for Thursday night’s game against New Orleans. It is not known if Freeman will have time in a short practice week to be able to play against the Saints.
Safety Kemal Ishmael, who has missed two games with a concussion, also could return this week.
Quinn had no update on wide receiver Julio Jones, who briefly left Sunday’s 35-22 loss to Tampa Bay with a right shoulder injury. Even after returning to the game, Jones appeared to be bothered by the injury.

Boil water order issued for Margate, parts of Coconut Creek
by Cristina AlexanderMARGATE, FLA. (WSVN) - A boil water noticed has been issued for residents of Margate and portions of Coconut Creek.
The city issued the order after a temporary power outage of the high service pumps at the Water Treatment Plant on Wednesday caused the pressure to drop below the 20 psi regulatory limit during a routine test of the Emergency Power Generator System.
The parts of Margate and Coconut Creek affected by the boil water order are:
- Royal Palm Boulevard
- Southgate Boulevard
- Rock Island Road
- West Atlantic Boulevard
- North State Road 7
- Coconut Creek Parkway
- Banks Road
- Lyons Road South
Residents in the affected areas are urged to boil water for one minute before using it to drink, cook, make ice, brush their teeth or wash dishes.
The boil water order will remain in effect until bacteriological surveys show the water is safe to drink.


Only Chrome or Firefox are supported in MirrorGate. Please use one of those browsers to access.
Thanks and sorry for the inconvenience.

All property accessor methods are evaluated 034 * relative to this root node. A good use case for a {@code SubnodeConfiguration} is when multiple properties from a 035 * specific sub tree of the whole configuration need to be accessed. Then a {@code SubnodeConfiguration} can be created 036 * with the parent node of the affected sub tree as root node. This allows for simpler property keys and is also more 037 * efficient. 038 * </p> 039 * <p> 040 * By making use of a tracked node as root node, a {@code SubnodeConfiguration} and its parent configuration initially 041 * operate on the same hierarchy of configuration nodes. So if modifications are performed at the subnode configuration, 042 * these changes are immediately visible in the parent configuration. Analogously will updates of the parent 043 * configuration affect the {@code SubnodeConfiguration} if the sub tree spanned by the {@code SubnodeConfiguration}'s 044 * root node is involved. 045 * </p> 046 * <p> 047 * Note that by making use of a {@code NodeSelector} the {@code SubnodeConfiguration} is not associated with a physical 048 * node instance, but the selection criteria stored in the selector are evaluated after each change of the nodes 049 * structure. As an example consider that the selector uses a key with an index into a list element, say index 2. Now if 050 * an update occurs on the underlying nodes structure which removes the first element in this list structure, the 051 * {@code SubnodeConfiguration} still references the element with index 2 which is now another one. 052 * </p> 053 * <p> 054 * There are also possible changes of the underlying nodes structure which completely detach the 055 * {@code SubnodeConfiguration} from its parent configuration. For instance, the key referenced by the 056 * {@code SubnodeConfiguration} could be removed in the parent configuration. If this happens, the 057 * {@code SubnodeConfiguration} stays functional; however, it now operates on a separate node model than its parent 058 * configuration. Changes made by one configuration are no longer visible for the other one (as the node models have no 059 * longer overlapping nodes, there is no way to have a synchronization here). 060 * </p> 061 * <p> 062 * When a subnode configuration is created, it inherits the settings of its parent configuration, e.g. some flags like 063 * the {@code throwExceptionOnMissing} flag or the settings for handling list delimiters) or the expression engine. If 064 * these settings are changed later in either the subnode or the parent configuration, the changes are not visible for 065 * each other. So you could create a subnode configuration, and change its expression engine without affecting the 066 * parent configuration. 067 * </p> 068 * <p> 069 * Because the {@code SubnodeConfiguration} operates on the same nodes structure as its parent it uses the same 070 * {@code Synchronizer} instance per default. This means that locks held on one {@code SubnodeConfiguration} also impact 071 * the parent configuration and all of its other {@code SubnodeConfiguration} objects. You should not change this 072 * without a good reason! Otherwise, there is the risk of data corruption when multiple threads access these 073 * configuration concurrently. 074 * </p> 075 * <p> 076 * From its purpose this class is quite similar to {@link SubsetConfiguration}. The difference is that a subset 077 * configuration of a hierarchical configuration may combine multiple configuration nodes from different sub trees of 078 * the configuration, while all nodes in a subnode configuration belong to the same sub tree. If an application can live 079 * with this limitation, it is recommended to use this class instead of {@code SubsetConfiguration} because creating a 080 * subset configuration is more expensive than creating a subnode configuration. 081 * </p> 082 * <p> 083 * It is strongly recommended to create {@code SubnodeConfiguration} instances only through the 084 * {@code configurationAt()} methods of a hierarchical configuration. These methods ensure that all necessary 085 * initializations are done. Creating instances manually without doing proper initialization may break some of the 086 * functionality provided by this class. 087 * </p> 088 * 089 * @since 1.3 090 */ 091public class SubnodeConfiguration extends BaseHierarchicalConfiguration { 092 /** Stores the parent configuration. */ 093 private final BaseHierarchicalConfiguration parent; 094 095 /** The node selector selecting the root node of this configuration. */ 096 private final NodeSelector rootSelector; 097 098 /** 099 * Creates a new instance of {@code SubnodeConfiguration} and initializes it with all relevant properties. 100 * 101 * @param parent the parent configuration 102 * @param model the {@code TrackedNodeModel} to be used for this configuration 103 * @throws IllegalArgumentException if a required argument is missing 104 */ 105 public SubnodeConfiguration(final BaseHierarchicalConfiguration parent, final TrackedNodeModel model) { 106 super(model); 107 if (parent == null) { 108 throw new IllegalArgumentException("Parent configuration must not be null!"); 109 } 110 if (model == null) { 111 throw new IllegalArgumentException("Node model must not be null!"); 112 } 113 114 this.parent = parent; 115 rootSelector = model.getSelector(); 116 } 117 118 /** 119 * Returns the parent configuration of this subnode configuration. 120 * 121 * @return the parent configuration 122 */ 123 public BaseHierarchicalConfiguration getParent() { 124 return parent; 125 } 126 127 /** 128 * Returns the selector to the root node of this configuration. 129 * 130 * @return the {@code NodeSelector} to the root node 131 */ 132 public NodeSelector getRootSelector() { 133 return rootSelector; 134 } 135 136 /** 137 * Closes this sub configuration.

Introduction
With data from the 1975 World Almanac and Statistical Abstracts of the United States, the USArrests data set within the R datasets package brings together 1973 data on Assault, Rape & Murder arrests by state.
The USArrests data set is a data frame with 4 variables for each state:
- Assault - number of Assault arrests per 100,000 people.
- Rape - number of Rape arrests per 100,000 people.
- UrbanPop - percentage of urban population.
- Murder - number of Murder arrests per 100,000 people.
I chose this data set for the challenge of creating a choropleth, and because the data is easily accessible to R (this package is included in a standard R installation).

Morio Muscat and Friends
by Allison MarkinWine: Morio Muscat and Friends, 2018
Winery: Wild Goose, Okanagan Falls
Why drink it? Morio Muscat is an interesting grape, a cross between Silvaner from Germany and Pinot Blanc, and the friendly addition here is Muscat Ottonel, notable for its slightly sweet characteristics. That all said, if you like your white wines dry, this may not be for you. But if you’re willing to branch out, the nose on this is full of orange blossoms and citrus groves with nutmeg and clove hints. Highly aromatic, a sip is more balanced than you might expect, with grapefruit and candied lemon peel with a satisfying and refreshing finish.
Price: $20
Pair with: Potato and sweet corn chowder, and pour a bit of this wine in the pot and let it simmer a bit. Savory corn bread muffins at brunch on the side of a frittata, or banana bread. Or simply keep a bottle chilled to enjoy with friends and a variety of potato chip flavours.
Music pairing: I’ll Be There For You, The Rembrandts

IVORY is a CSS framework, specially created for web applications and committed to improve the experience of users. It gives you all the basic integrants to build your pages faster and easier.
The project IVORY was started in July 2012, as a side project by a Software Engineer named Lakshmikanth Vallampati. The initial idea of the project IVORY is to create the CSS library for forms.
The first version of IVORY Forms released.
The IVORY Forms enhanced by adding more components like grid-system(non-responsive), tooltips, tabs, accordion and toggle switch. IVORY Forms turned into IVORY Framework.
The responsiveness added to v2. IVORY source code published in GitHub for the first time.
IVORY reached new milestone.
Satyasai Vallampati joined in IVORY core team. The IVORY Framework is revamped with new design system and advanced grid system. Version 4 released.
Run the below command to install via npm
npm i ivoryui-ivory
Import the following files to your project
node_modules/ivoryui-ivory/ivory-icons.css
node_modules/ivoryui-ivory/ivory.min.css
<link rel="stylesheet" href="https://unpkg.com/ivoryui-ivory/ivory.min.css" />
<link rel="stylesheet" href="https://unpkg.com/ivoryui-ivory/ivory-icons.css" />
IVORY color system is combination of 12 primary colors and a neutral color. Each color has a adequate purpose. The color system designed in a way to help create a theme that is harmonious, ensures accessible text, and distinguishes UI elements and surfaces from one another.
Each color in IVORY's color system has 10 variants (both dark & light variants). Each variant can then be applied to your UI in different ways.
Neutral color is widely used in the interface as surface color, background, borders, dividers, heading, text and etc. The neutral color palette is balanced with readability, aesthetics and usability. The neutral color palette of IVORY, as shown on the right:
IVORY uses the Montserrat Font Family designed by Julieta Ulanovsky, to greatly enhance the user experience and elegance of the interface. IVORY use Montserrat as the base font and then also provides a set of fallback font libraries to maintain readability for screens on different platforms and browsers.
font-family: 'Montserrat', 'Helvetica Neue', Helvetica, Arial, sans-serif;
Montserrat font family has 10 differnt font-weights from 100 to 900. For good readability, IVORY prefers to use light(300), regular(400), medium(500), semi-bold(600), bold(700) font weights.
IVORY type system has 11 styles.
| Style | Font Weight | Font Size | Line Height |
|---|---|---|---|
Heading1 |
500 | 32px | 44px |
Heading2 |
500 | 28px | 40px |

ISLAND OF DR. MOREAU and A TIME TO KILL A film review by Peter Dizozza Copyright 1996 Peter Dizozza
I saw Dr. Moreau (director John Frankenheimer) and A Time to Kill (director Joel Schumacher).
Moreau has the great H.G. Wells story, the second of the summer (war of the worlds being independence day). The stars get their individual death scenes which disjoints the film, and then the lead actor tells us and the cat girl what we could have learned visually with him as he searched the lab records, but there are surprising Brando scenes. He's so like a relative up there. I feel such affection for the man. He was really sweet in this film. I think he was actually trying to do something on screen. Rex Reed referred to his refinement as his Eleanor Roosevelt immitation. Val Kilmer was Jim Morrison, and in this film he acts like one of his disciples. Say, his last movie was a Schumacher film, Batman Returns, the Scorpio Rising homage to Kenneth Anger.
Schumacher makes good films. The affection in this legal one goes to Donald Sutherland.  Donald Sutherland is from Nova Scotia and I've been there so again, I feel like I'm related to the man. Did you see Kelly's Heroes? I particularly like his MASH role. Then he became disturbing starting with Bertollucci's 1900 and Eye of the Needle.
Grisham's story carries a lot of plots. The most interesting conflict is the interpretation of the lawyer's non-action in the face of the immenent revenge murder. First we get his reason, then finally his wife gets it, and the near affair ends. Ms. Bullock, the other woman, gets short shrifted if you ask me. She's almost left hanging in the field until the mickey mouse saviour comes along. Was I wrong about feeling I was left hanging about some of the plot elements. The appearance of the Klan seemed to spill over from the Moreau film.
The best thing about Moreau is the hour and a half length. Remember the Laughton film of the thirties, Island of Lost Souls. That one handled the animal misegenation issues well.
A Time to Kill and the Island of Lost Souls, two films dealing with the issue of misegination. The refinement of animal instinct is unique to Moreau.
I also saw Ms. Tyler in Bertolucci's Stealing Beauty, a funny story in that she's not only the last virgin in Northern Italy, but a virgin looking for the identity of her father, when it's perfectly obvious she's the Arrowsmith singer's daughter, but apparently she didn't know that in real life until her mother left her a cryptic letter, like the one in the film. A RIDDLE solvable by a glance in the mirror while watching MTV.

| FilteredPuzzleSolver<T extends PuzzleState<T>> |
Abstract base for puzzle solvers that use a
PuzzleStateFilter
to keep track (possibility only approximately) of which states have
been seen during the search for a solution. |
The primary abstraction is PuzzleState
, which defines a
successors function and test for whether a state represents a solution.
There is no separate puzzle type, because an initial puzzle state
instance essentially defines a puzzle: Find a sequence of states
starting with the initial state and ending with a solution state
with each element of the sequence other than first being a successor
of the previous element of the sequence.
To define a new kind of puzzle, implement the PuzzleState
methods
isSolution
,
successors
,
and predecessor
,
and optionally any of the other methods.
The predecessor method should be defined
for states that are produced by s0.successors()
to be
s0
, otherwise it should be empty (initial states have no predecessor).
It is also acceptable to define predecessor as always empty,
in which case solution lists produced by FilteredPuzzleSolver
will contain only the solution state, which might be acceptable
if the solution state itself contains all the relevant information.
States must be usable as map keys, so override equals
and hashCode
properly.
Do not include a reference to a predecessor in the implementation
of these methods; a state might be reachable in two different ways, but we do not
in general want approximate containment tests to return false negatives from
two otherwise equal states comparing unequal due to different predecessors.
The initialized
method may be implemented
to avoid unnecessary computation on states that might have already been seen.
To define a new general-purpose solver, extend
FilteredPuzzleSolver
by
implementing solutionState
.
Use filterState
before searching
from any state returned by the state.successors()
method.
Two concrete implementations of FilteredPuzzleSolver
are
provided, DfsPuzzleSolver
and BfsPuzzleSolver
,
correspondingly using depth-first and breadth-first search.
General-purpose solvers should allow users to provide a
PuzzleStateFilter
supplier.


Since this is your first time trying the game, here is a tutorial!
1. The idea of the game is to take pictures of birds in focus.
2. The more in focus the pictures, the more you get paid!
RARITY: This game has four rarities of birds: common, rare, epic, and legendary. Rarer birds are harder to take pictures of because they are found less often and they fly away quickly. However, if you are able to take a picture of a more rare bird, you will be paid more for it!
CONTROLS: To focus your camera, you can press the left and right arrow keysor the "a" and "d" keys; or you can press the focus buttons on the screen. To take a picture, press the up arrow key, the "w" button, or the button with the camera icon.
PROGRESSION: You will start the game with just three known common birds. As you gain money, you can learn what new, rarer, birds look like so you can start taking photos of them. To learn this, open the market by pressing on the market button. Your progress will be stored so you can close the browser whenever you want! Have fun!

Redux Fundamentals, Part 5: UI and ReactWhat You'll Learn
- How a Redux store works with a UI
- How to use Redux with React
#
IntroductionIn Part 4: Store, we saw how to create a Redux store, dispatch actions, and read the current state. We also looked at how a store works inside, how enhancers and middleware let us customize the store with additional abilities, and how to add the Redux DevTools to let us see what's happening inside our app as actions are dispatched.
In this section, we'll add a User Interface for our todo app. We'll see how Redux works with a UI layer overall, and we'll specifically cover how Redux works together with React.
#
Integrating Redux with a UIRedux is a standalone JS library. As we've already seen, you can create and use a Redux store even if you don't have a user interface set up. This also means that you can use Redux with any UI framework (or even without any UI framework), and use it on both client and server. You can write Redux apps with React, Vue, Angular, Ember, jQuery, or vanilla JavaScript.
That said, Redux was specifically designed to work well with React. React lets you describe your UI as a function of your state, and Redux contains state and updates it in response to actions.
Because of that, we'll use React for this tutorial as we build our todo app, and cover the basics of how to use React with Redux.
Before we get to that part, let's take a quick look at how Redux interacts with a UI layer in general.
#
Basic Redux and UI IntegrationUsing Redux with any UI layer requires a few consistent steps:
- Create a Redux store
- Subscribe to updates
-
Inside the subscription callback:
- Get the current store state
- Extract the data needed by this piece of UI
- Update the UI with the data
- If necessary, render the UI with initial state
- Respond to UI inputs by dispatching Redux actions
Let's go back to the the counter app example we saw in Part 1 and see how it follows those steps:
No matter what UI layer you're using, Redux works this same way with every UI. The actual implementations are typically a bit more complicated to help optimize performance, but it's the same steps each time.
Since Redux is a separate library, there are different "binding" libraries to help you use Redux with a given UI framework. Those UI binding libraries handle the details of subscribing to the store and efficiently updating the UI as state changes, so that you don't have to write that code yourself.
#
Using Redux with ReactThe official React-Redux UI bindings library is a separate package from the Redux core. You'll need to install that in addition as well:
(If you don't use npm, you may grab the latest
UMD build from unpkg (either a
development
or a
production
build). The UMD build exports a global called
window.ReactRedux
if you add it to your
page via a <script>
tag.)
For this tutorial, we'll cover the most important patterns and examples you need to use React and Redux together, and see how they work in practice as part of our todo app.
info
See the official React-Redux docs at https://react-redux.js.org for a complete guide on how to use Redux and React together, and reference documentation on the React-Redux APIs.
#
Designing the Component TreeMuch like we designed the state structure based on requirements, we can also design the overall set of UI components and how they related to each other in the application.
Based on the list of business requirements for the app, at a minimum we're going to need this set of components:
-
<App>
: the root component that renders everything else.-
<Header>
: contains the "new todo" text input and the "complete all todos" checkbox -
<TodoList>
: a list of all currently visible todo items, based on the filtered results-
<TodoListItem>
: a single todo list item, with a checkbox that can be clicked to toggle the todo's completed status, and a color category selector
-
-
<Footer>
: Shows the number of active todos and controls for filtering the list based on completed status and color category
-
Beyond this basic component structure, we could
potentially divide the components up in several
different ways. For example, the
<Footer>
component
could be one larger component, or it could
have multiple smaller components inside like
<CompletedTodos>
,
<StatusFilter>
, and
<ColorFilters>
. There's no
single right way to divide these, and you'll find
that it may be better to write larger components or
split things into many smaller components depending on
your situation.
For now, we'll start with this small list of components to keep things easier to follow. On that note, since we assume that you already know React, we're going to skip past the details of how to write the layout code for these components and focus on how to actually use the React-Redux library in your React components.
Here's the initial React UI of this app looks like before we start adding any Redux-related logic:
useSelector
#
Reading State from the Store with
We know that we need to be able to show a list of todo
items. Let's start by creating a
<TodoList>
component that can read
the list of todos from the store, loop over them, and
show one <TodoListItem>
component
for each todo entry.
You should be familiar with
React hooks like useState
, which can be called in React function components to
give them access to React state values. React also
lets us write
custom hooks, which let us extract reusable hooks to add our own
behavior on top of React's built-in hooks.
Like many other libraries, React-Redux includes its own custom hooks, which you can use in your own components. The React-Redux hooks give your React component the ability to talk to the Redux store by reading state and dispatching actions.
The first React-Redux hook that we'll look at is
the
useSelector
hook, which
lets your React components read data from the Redux
store.
useSelector
accepts a single function,
which we call a selector function.
A selector is a function that takes the entire
Redux store state as its argument, reads some value
from the state, and returns that result.
For example, we know that our todo app's Redux
state keeps the array of todo items as
state.todos
. We can write a small
selector function that returns that todos array:
Or, maybe we want to find out how many todos are currently marked as "completed":
So, selectors can return values from the Redux store state, and also return derived values based on that state as well.
Let's read the array of todos into our
<TodoList>
component. First,
we'll import the useSelector
hook
from the react-redux
library, then call
it with a selector function as its argument:
The first time the
<TodoList>
component renders, the
useSelector
hook will call
selectTodos
and pass in the
entire Redux state object. Whatever the
selector returns will be returned by the hook to your
component. So, the const todos
in our
component will end up holding the same
state.todos
array inside our Redux store
state.
But, what happens if we dispatch an action like
{type: 'todos/todoAdded'}
? The
Redux state will be updated by the reducer, but our
component needs to know that something has changed so
that it can re-render with the new list of todos.
We know that we can call
store.subscribe()
to listen for changes
to the store, so we could try writing the
code to subscribe to the store in every component.
But, that would quickly get very repetitive and hard
to handle.
Fortunately,
useSelector
automatically subscribes
to the Redux store for us!
That way, any time an action is dispatched, it will
call its selector function again right away.
If the value returned by the selector changes from
the last time it ran, useSelector
will
force our component to re-render with the new
data. All we have to do is call
useSelector()
once in our component, and
it does the rest of the work for us.
However, there's a very important thing to remember here:
caution
useSelector
compares its results
using strict ===
reference
comparisons, so the component will re-render any
time the selector result is a new
reference!
This means that if you create a new reference in
your selector and return it, your component could
re-render every time an action has been
dispatched, even if the data really isn't
different.
For example, passing this selector to
useSelector
will cause the component to
always re-render, because
array.map()
always returns a new array
reference:
tip
We'll talk about one way to fix this issue later in this section. We'll also talk about how you can improve performance and avoid unnecessary re-renders using "memoized" selector function in Part 7: Standard Redux Patterns.
It's also worth noting that we don't have to
write a selector function as a separate variable. You
can write a selector function directly inside the call
to useSelector
, like this:
useDispatch
#
Dispatching Actions with
We now know how to read data from the Redux store into
our components. But, how can we dispatch actions to
the store from a component? We know that outside of
React, we can call
store.dispatch(action)
. Since we
don't have access to the store in a component
file, we need some way to get access to the
dispatch
function by itself inside our
components.
The React-Redux
useDispatch
hook
gives us the store's dispatch
method
as its result. (In fact, the implementation of the
hook really is return store.dispatch
.)
So, we can call
const dispatch = useDispatch()
in any
component that needs to dispatch actions, and then
call dispatch(someAction)
as needed.
Let's try that in our
<Header>
component. We know that we
need to let the user type in some text for a new todo
item, and then dispatch a
{type: 'todos/todoAdded'}
action containing that text.
We'll write a typical React form component that uses "controlled inputs" to let the user type in the form text. Then, when the user presses the Enter key specifically, we'll dispatch that action.
Provider
#
Passing the Store with
Our components can now read state from the store, and
dispatch actions to the store. However, we're
still missing something. Where and how are the
React-Redux hooks finding the right Redux store? A
hook is a JS function, so it can't automatically
import a store from store.js
by itself.
Instead, we have to specifically tell React-Redux what
store we want to use in our components. We do this by
rendering a <Provider>
component
around our entire <App>
, and
passing the Redux store as a prop to
<Provider>
. After we do this once, every component in the
application will be able to access the Redux store if
needs to.
Let's add that to our main
index.js
file:
That covers the key parts of using React-Redux with React:
-
Call the
useSelector
hook to read data in React components -
Call the
useDispatch
hook to dispatch actions in React components -
Put
<Provider store={store}>
around your entire<App>
component so that other components can talk to the store
We should now be able to actually interact with the app! Here's the working UI so far:
Now, let's look at a couple more ways we can use these together in our todo app.
#
React-Redux Patterns#
Global State, Component State, and FormsBy now you might be wondering, "Do I always have to put all my app's state into the Redux store?"
The answer is NO. Global state that is needed across the app should go in the Redux store. State that's only needed in one place should be kept in component state.
A good example of this is the
<Header>
component we wrote
earlier. We could keep the current text input
string in the Redux store, by dispatching an action in
the input's onChange
handler and
keeping it in our reducer. But, that doesn't give
us any benefit. The only place that text string is
used is here, in the
<Header>
component.
So, it makes sense to keep that value in a
useState
hook here in the
<Header>
component.
Similarly, if we had a boolean flag called
isDropdownOpen
, no other components in
the app would care about that - it should really stay
local to this component.
tip
In a React + Redux app, your global state should go in the Redux store, and your local state should stay in React components.
If you're not sure where to put something, here are some common rules of thumb for determining what kind of data should be put into Redux:
- Do other parts of the application care about this data?
- Do you need to be able to create further derived data based on this original data?
- Is the same data being used to drive multiple components?
- Is there value to you in being able to restore this state to a given point in time (ie, time travel debugging)?
- Do you want to cache the data (ie, use what's in state if it's already there instead of re-requesting it)?
- Do you want to keep this data consistent while hot-reloading UI components (which may lose their internal state when swapped)?
This is also a good example of how to think about forms in Redux in general. Most form state probably shouldn't be kept in Redux. Instead, keep the data in your form components as you're editing it, and then dispatch Redux actions to update the store when the user is done.
#
Using Multiple Selectors in a Component
Right now only our
<TodoList>
component is reading
data from the store. Let's see what it might look
like for the <Footer>
component to
start reading some data as well.
The <Footer>
needs to know three
different pieces of information:
- How many completed todos there are
- The current "status" filter value
- The current list of selected "color" category filters
How can we read these values into the component?
We can call useSelector
multiple times
within one component. In fact, this is actually a good idea -
each call to useSelector
should always
return the smallest amount of state possible.
We already saw how to write a selector that counts
completed todos earlier. For the filters values, both
the status filter value and the color filters values
live in the state.filters
slice. Since
this component needs both of them, we can select the
entire state.filters
object.
As we mentioned earlier, we could put all the input
handling directly into <Footer>
, or
we could split it out into separate components like
<StatusFilter>
. To keep this
explanation shorter, we'll skip the exact details
of writing the input handling and assume we've
got smaller separate components that are given some
data and change handler callbacks as props.
Given that assumption, the React-Redux parts of the component might look like this:
#
Selecting Data in List Items by ID
Currently, our <TodoList>
is
reading the entire state.todos
array and
passing the actual todo objects as a prop to each
<TodoListItem>
component.
This works, but there's a potential performance problem.
-
Changing one todo object means creating copies of
both the todo and the
state.todos
array, and each copy is a new reference in memory -
When
useSelector
sees a new reference as its result, it forces its component to re-render -
So, any time one todo object is updated
(like clicking it to toggle its completed status),
the whole
<TodoList>
parent component will re-render -
Then,
because React re-renders all child components
recursively by default, it also means that all of the
<TodoListItem>
components will re-render, even though most of them didn't actually change at all!
Re-rendering components isn't bad - that's how React knows if it needs to update the DOM. But, re-rendering lots of components when nothing has actually changed can potentially get too slow if the list is too big.
There's a couple ways we could try to fix this.
One option is to
wrap all the
<TodoListItem>
components in
React.memo()
, so that they only re-render when their props
actually change. This is often a good choice for
improving performance, but it does require that the
child component always receives the same props until
something really changes. Since each
<TodoListItem>
component is
receiving a todo item as a prop, only one of them
should actually get a changed prop and have to
re-render.
Another option is to have the
<TodoList>
component only read an
array of todo IDs from the store, and pass those IDs
as props to the child
<TodoListItem>
components. Then,
each <TodoListItem>
can use that ID
to find the right todo object it needs.
Let's give that a shot.
This time, we only select an array of todo IDs from
the store in <TodoList>
, and we
pass each todoId
as an
id
prop to the child
<TodoListItem>
s.
Then, in <TodoListItem>
, we can use
that ID value to read our todo item. We can also
update <TodoListItem>
to dispatch
the "toggled" action based on the
todo's ID.
There's a problem with this, though. We said
earlier that
returning new array references in selectors causes
components to re-render every time, and right now we're returning a new IDs array
in <TodoList>
. In this case, the
contents of the IDs array should be the same
if we're toggling a todo, because we're
still showing the same todo items - we haven't
added or deleted any. But, the array
containing those IDs is a new reference, so
<TodoList>
will re-render when it
really doesn't need to.
One possible solution to this is to change how
useSelector
compares its values to see if
they've changed. useSelector
can
take a comparison function as its second argument. A
comparison function is called with the old and new
values, and returns true
if they're
considered the same. If they're the same,
useSelector
won't make the component
re-render.
React-Redux has a shallowEqual
comparison
function we can use to check if the items
inside the array are still the same.
Let's try that:
Now, if we toggle a todo item, the list of IDs will be
considered the same, and
<TodoList>
won't have to
re-render. The one
<TodoListItem>
will get an updated
todo object and re-render, but all the rest of them
will still have the existing todo object and not have
to re-render at all.
As mentioned earlier, you can also use a specialized kind of selector function called a "memoized selector" to help improve component rendering, and we'll look at how to use those in another section.

What You've Learned
We now have a working todo app! Our app creates a
store, passes the store to the React UI layer using
<Provider>
, and then calls
useSelector
and
useDispatch
to talk to the store in our
React components.
info
Try implementing the rest of the missing UI features on your own! Here's a list of the things you'll need to add:
-
In
<TodoListItem>
component, use theuseDispatch
hook to dispatch actions to for changing the color category and deleting the todo -
In
<Footer>
, use theuseDispatch
hook to dispatch actions for marking all todos as completed, clearing completed todos, and changing the filter values.
We'll cover implementing the filters in Part 7: Standard Redux Patterns.
Let's see how the app looks now, including the components and sections we skipped to keep this shorter:
Summary
-
Redux stores can be used with any UI
layer
- UI code always subscribes to the store, gets the latest state, and redraws itself
-
React-Redux is the official Redux UI bindings
library for React
-
React-Redux is installed as a separate
react-redux
package
-
React-Redux is installed as a separate
-
The
useSelector
hook lets React components read data from the store-
Selector functions take the entire store
state
as an argument, and return a value based on that state -
useSelector
calls its selector function and returns the result from the selector -
useSelector
subscribes to the store, and re-runs the selector each time an action is dispatched. -
Whenever the selector result changes,
useSelector
forces the component to re-render with the new data
-
Selector functions take the entire store
-
The
useDispatch
hook lets React components dispatch actions to the store-
useDispatch
returns the actualstore.dispatch
function -
You can call
dispatch(action)
as needed inside your components
-
-
The
<Provider>
component makes the store available to other React components-
Render
<Provider store={store}>
around your entire<App>
-
Render
#
What's Next?Now that our UI is working, it's time to see how to make our Redux app talk to a server. In Part 6: Async Logic, we'll talk about how asynchronous logic like timeouts and AJAX calls fit into the Redux data flow.

#assign namingconvention = "true">
Ebean has a Naming Convention API to map column names to property names. It also maps entity to table names and can take into account database schema and catalog if required.
The default UnderscoreNamingConvention
converts column names with underscores into
normal java camel case property names (e.g. "first_name" maps to "firstName").
Alternatively you can use the MatchingNamingConvention
or implement your own naming convention.
The MatchingNamingConvention names column names to match property names and table names to match entity names. Ebean follows the JPA specification which states that the in the case of no annotations the name of the class will be take as the table name and the name of a property will be taken as the name of the column.
