Quick Start Guide
This guide describes how to create a Crosswalk web application, and how to create a hybrid application with Crosswalk XWalkView support.
Create Crosswalk Web Application
Prerequisites
Creation
Create a demo application
org.example.foo
> crosswalk-app create org.example.foo
Develop the application
In the directory
org.example.foo/app
the template filesicon.png
,index.html
andmanifest.json
have already been created.The
manifest.json
file is the main configuration interface for your web application. It is cross platform. Refer to the iOS Manifest page for more details on the iOS platform.Build the application
> cd org.example.foo > crosswalk-app build
If the build succeeds the file
foo.ipa
will be in the directory.Install the application
Open iTunes. Connect an iOS device (iPhone/iPad) which is already registered in your development group. Select the
Application
page, dragfoo.ipa
into theApplications
list, and sync.'foo.ipa
will be installed on the iOS device.
Create Crosswalk Hybrid Application
Create the application project
Open Xcode. Create an iOS application project with the "Single View Application" template in the working directory. For this example, we use "Echo". Use Swift for convenience.
Use CocoaPods to integrate the
crosswalk-ios
library and Crosswalk extensions (if needed) into the demo application. For the CocoaPods installation and usage, please refer to: CocoaPods.In the
Echo
directory, create a file calledPodfile
:> cd Echo; > touch Podfile;
With the contents as below:
platform :ios, '8.1' use_frameworks! pod 'crosswalk-ios', '~> 1.2'
This tells CocoaPods that the deploy target is iOS 8.1+ and to integrate library
crosswalk-ios
with the latest version of1.2.x
. Remember to adduse_frameworks!
becausecrosswalk-ios
is partly written in Swift and it has to be built as a framework instead of a static library.Install
Pods
target into the project. Quit the Xcode first, then in theEcho
directory, use command:> pod install
After the installation, you will find an
Echo.xcworkspace
is generated, and CocoaPods output will notify you to use this workspace instead of theEcho.xcodeproj
from now on.Open the
Echo.xcworkspace
. There will be two projects:Echo
andPods
.- For quick test, replace the contents of the auto-generated
ViewController.swift
with the corresponding file in crosswalk-ios/AppShell/AppShell/ViewController.swift, which has set up aXWalkView
instance for you already.
- For quick test, replace the contents of the auto-generated
Create a directory called
www
inEcho
for the HTML5 files and resources.Create the
index.html
file as your entry page with the contents as follows:  <meta name='viewport' content='width=device-width' /> <title>Echo demo of Crosswalk</title>
Echo Demo of Crosswalk

Add the
www
directory into the project.In
File
->Add Files to "Echo"...
, choose thewww
directory and selectCreate folder reference
.Create
manifest.plist
to describe the application's configuration.In
File
->New...
->File...
, chooseiOS
->Resource
->Property List
. Create a plist file with namemanifest.plist
inEcho
directory. This manifest file will be loaded at application startup;Add an entry with the key:
start_url
and the string value:index.html
. This is the entry page.XWalkView
will locate it in thewww
directory.
The Echo
demo is ready to run now. Press 'Run' button and it will be deployed and run on your iOS simulator.
This is the first step in building the Echo demo. If you need to know how to setup a hybrid project with your own Crosswalk extension, please go to: Extension for more details.

Description
The Container Sample illustrates a container and container objects. The container has parent container objects and child container objects. The initial view is treeIconView but can be changed to any view including textView, flowedTextView, nameView, detailsView, treeTextView, treeNameView, and iconView. The sample can also select or deselect all container objects. In addition, a filter is provided for viewing only a select parent container object. Classes used include IContainerControl, IContainerObject, IContainerColumn, and IContainerControl::FilterFn.
Concept
Creates and displays a container. The menu items change container views, select or deselect container objects (in non-tree views), and filters to display only selected items ( PM compatible container only)
Task
From the menu, you can change the view for the container and sort or filter the container's contents.

You often want to convert from what the model sends you to
a form more useful to JavaScript. For example,
contacts might be returned from the server with dates that look like:
"1982-10-20". We can model to convert it to something closer
to new Date(1982,10,20). We can do this in two ways:
Way 1: Setters
The [jQuery.Model.prototype.attrs attrs]
and [jQuery.Model.prototype.attr attr] function look for
a setATTRNAME function to handle setting the
date property.
By providing a function that takes the raw data and returns
a form useful for JavaScript, we can make our models (which
use attrs and attr) automatically convert server data.
The following demo shows converting a contact's birthday into
a string.
Way 2: Convert
If you have a lot of dates, Setters won't scale well.
Instead, you can set the type of
an attribute and provide a function to convert that type.
The following sets the birthday attribute to "date" and provides a date conversion function:
Serialization occurs before the model is saved. This allows you to prepare your model's attributes before they're sent to the server.
By default every attribute will be passed through the 'default' serialization method that will return the value if the property holds a primitive value (string, number, ...), or it will call the "serialize" method if the property holds an object with the "serialize" method set.
You can set the serialization methods similar to the convert methods:

This update is based on the equation:
:math:`B_{new}(s') = n O(z|s',a) \sum_s T(s'|s,a)B(s)`.
Args:
current_histogram (~pomdp_py.representations.distribution.Histogram)
is the Histogram that represents current belief.
real_action (~pomdp_py.framework.basics.Action)
real_observation (~pomdp_py.framework.basics.Observation)
observation_model (~pomdp_py.framework.basics.ObservationModel)
transition_model (~pomdp_py.framework.basics.TransitionModel)
oargs (dict) Additional parameters for observation_model (default {})
targs (dict) Additional parameters for transition_model (default {})
normalize (bool) True if the updated belief should be normalized
static_transition (bool) True if the transition_model is treated as static;
This basically means Pr(s'|s,a) = Indicator(s' == s). This then means
that sum_s Pr(s'|s,a)*B(s) = B(s'), since s' and s have the same state space.
This thus helps reduce the computation cost by avoiding the nested iteration
over the state space; But still, updating histogram belief requires
iteration of the state space, which may already be prohibitive.
next_state_space (set) the state space of the updated belief. By default,
this parameter is None and the state space given by current_histogram
will be directly considered as the state space of the updated belief.
This is useful for space and time efficiency in problems where the state
space contains parts that the agent knows will deterministically update,
and thus not keeping track of the belief over these states.
Returns:
Histogram: the histogram distribution as a result of the update

The theme to this tutorial is "lead by mistake". We will present you with an Alloy model which is well formed, but which initially makes some conceptual mistakes and has some shortcomings. We will then go through the process of identifying those mistakes, understanding why they occurred, and fixing them. We will iterate this process until we have a final draft.
We choose this approach, not only because it imitates the actual modeling process, but also because it will allow us to begin with a simple model, using only a small part of Alloy syntax, and gradually introduce complexities and more advanced syntax as it is needed. As a result, this tutorial will not introduce you to every Alloy command, but we will make sure you are comfortable with the important ones.
The goal of a writing a model is to describe some aspect of a system (but not the entire system), constrain it to exclude ill-formed examples, and check properties about it. For instance, you might describe the procedure a company uses to reroute mail internally, add some constraints about how the mail carriers behave, and then check to see if each piece of mail either gets to its destination or returned to sender. Your modeling tool (in this case, Alloy), would then either say "this property always holds for problems up to size X" or "this property does not always hold, and here is a counter example".
There are two kinds of problems that can arise:
Alloy is similar to several other existing languages and modeling techniques, but with several key differences.
We begin our tutorial with a simple model of a file system. It has a notion of a "file system object" which can be either a file or a directory. Every file system object knows its parent, and directories also know their contents. We will also create the notion of a "root directory", which resides at the top of the file system.
We will begin by defining files, directories, and file system objects, and make sure that they have the appropriate fields (parent, contents, etc.). We then show how to write simple facts to constrain the file system and to impose simple sanity constraints. For instance: every file system object must be either a file or a directory (not both, not neither); the file system is connected, the root has no parent; and so on.
It is easy to forget simple constraints like this, since they are so obvious to our intuition. We will show you how to view example file systems to make sure that they do not have any bizarre behaviour that you wished to preclude.
We will show you how to make assertions about properties you think (or hope) are true as a result of the sanity constraints you wrote. We'll show you how to check these assertions, and what to do when they fail to hold. For instance, we will verify that a file system is acyclic, even though we do not explicitly force it to be so.
The file system we write will have some shortcomings; most prominently, it will be static. In the following lessons, we will introduce dynamic operations, such as move and delete.
By the end of the first lesson, you will have written a simple static file system, constrained it to exclude ill-formed file-systems, and verified some properties about it.


The guess mode enable to replay games stored in SGF collections, giving a result depending on the number of correctly guessed moves. Drago stores the list of the replayed games and the best scores for each one.
A game session is started with the Replay/Replay session menu. The options of the session are:
The selection of the game to be replayed can be done as follows:
A game can be replayed with the user playing with Black, White or both colors.
A game can be fully replayed, limited to its beginning by choosing the Fuseki mode or started from the current position of the current game. In fuseki mode, an input box enables to select the number of moves to replay.
It is possible to start from the current position only when the current game is selected.
It is possible to have only one attempt per move. In that case, the correct move is played as soon as the user has played an incorrect move. It is also possible to have an unlimited number of attempts. In that case, a hint is displayed to inform about the distance to the correct move.
While replaying a game, the following commands are available:
If an unlimited number of attempts has been selected, a hint is displayed to inform about the distance to the correct move. If the correct move cannot be found, it is possible to go forward by using the next move command.
When the game is over, Drago displays the score for the replayed game. The score is the number of correctly replayed moves expressed as a percentage of the number of moves in the game.
The best scores reached for a game are stored and can be displayed with the Replay/Index command. This index stores for each game: the number of times the game has been replayed, the best scores for the three possible selections of color (Black, White or both) and for the full game or fuseki modes.


The Casiotone is back! New portable keyboards for beginners released
by Ben RogersonThe Casiotone is back! New portable keyboards for beginners released
Popular with families and used by countless garage bands who couldn’t afford anything else, the Casiotone range of portable keyboards was a fixture in the early ‘80s. Now Casio has released a revamped line-up of Casiotone models for the next generation of players.
In many ways, the CT-S200, CT-S300 and LK-S250 are cut from similar cloth to their predecessors, with each offering a wide range of built-in sounds and rhythms (400 and 122 respectively), plus 50 patterns in Dance Music Mode. You also get USB MIDI and a rechargeable battery.
Thanks to slimline chassis’, weight has been kept down to six pounds, and there are 61 full-size keys. Portability is aided by the inclusion of a carry handle.
Announced at Summer NAMM, the Casiotones are in stores now, all ready to find their way under Christmas trees. Prices are $109 for the CT-S200, $139 for the CT-S300, and $159 for the LK-S250.

eRegister Installation Manual
This document attempts to standardize how we prepare our servers to be ready for deployment at health facilities.
Before we follow the steps on how to prepare the server, we first have to install Ubuntu Server 18.04 LTS from Ubuntu Site
Installing Docker
- To install Docker, please follow the instructions detailed in https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04. these instructions were written for Ubuntu 16 but work perfectly for Ubuntu 18
Pulling the docker image and running it as a container
- In situations of poor internet connectivity where we're committing and sharing images using sneakernet, please follow the guide in here
- To pull the docker, it's not necessary to login from the terminal, just run the following:
docker pull omrsregrepo/bahmni_base:25012020_release
- After the image has been pulled you should be able to see it when you do
docker images
- A container is a running instance of an image. The last step is to run our image to make container with
docker run -e container_name=openmrseregister -it -d --restart always -p 443:443 -p 80:80 -p 8069:8069 -p 8000:8000 --privileged --name openmrseregister -v openmrseregister:/openmrseregister omrsregrepo/bahmni_base:25012020_release /bin/bash
- To check that indeed we have a container running, you can do
docker ps
. - Navigate into the container using the command,
docker exec -it openmrseregister bash
- Once you have landed into the container, make sure that you're in the / directory and then start mysqld service with
services mysqld start
, login to a database without a password and then run the command below: source openmrs.sql
- After running the command above, do
use openmrs
and then dosource OpenMRS_Start_up_Schema_V1.sql
Starting Services
Often times, we're going to encounter situations where a container is running but the services inside the container are not, to start your services running the following commands in this order:
1. service httpd start
2. service mysqld start
3. service openmrs start
4. service bahmni-reports start
Now you should be able to see eRegister when you browse to http://server_IP/bahmni/home. you'll use the IP address of your server
Enabling/Disabling Locations
Depending on the health facility where the server will be deployed, we'll have to either enable or disable locations in the database. To do all of these, it is highly recommended that we run all of our sql queries through phpMyAdmin and shy away from using CLI. Browse to http://<IP_ADDRESS>/mydb and use the following credentials. remember to use your IP address
- username:
- password:
On the left pane, you'll see a list of databases, click on openmrs
. All of the locations are managed by a location
table. If for example you're in Motebang Hospital, to see all of the locations for Motebang Hospital, run the following query:
SELECT location_id, name, retired
FROM location
WHERE name LIKE '%mote%'
1
is for when retired is TRUE
and 0
is when retired is FALSE
. To enable locations we have to set retired to 0
.
* So it will be done with the following UPDATE
query:
UPDATE location
SET retired = 0,
WHERE location_id=121;
to enable Motebang Hospital
* So it will be done with the following UPDATE
query:
UPDATE location
SET retired = 0,
WHERE location_id=122;
to enable ART Corner Motebang Hospital
* ...and so on and so fourth...

FOR ANY NEED
ENTRANCE ANTIPHON
I am the salvation of the people, says the Lord. Should they cry to me in any distress, I will hear them, and I will be their Lord for ever.
COLLECT
O God, our refuge in trials, our strength in sickness, our comfort in sorrow, spare your people, we pray, that, though rightly chastised now by affliction, they may find relief at last through your loving mercy. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.
PRAYER OVER THE OFFERINGS
Accept in compassion, Lord, we pray, the offerings of your family, that under your protective care they may never lose what they have received but attain the gifts that are eternal. Through Christ our Lord.

PRAYER AFTER COMMUNION
We pray, O
Lord, that in receiving your Sacrament we may experience help in mind and body,
so that, kept safe in both, we may glory in the fullness of heavenly healing. Through
Christ our Lord.


Webpage Roaster - About
Purpose
The Webpage Roaster (aka "Roaster") is designed to display WebPageTest (WPT) results in easy-to-read and easy-to-navigate formats and to promote new visualisations of performance data and analyses. It complements WPT results displays rather than replacing them; it is designed to display additional details for page objects to help users of WebPageTest understand more about their page construction and why objects are the size they are, e.g. image metadata and quality.
To Do
I expect to develop Roaster over time and introduce new features and deliver more insights into improving page performance.
Background
Roaster has evolved from another of my tools, the Webpage Toaster (aka "Toaster"). That was a proprietry tool I wrote whilst working as a Web Performance Consultant at NCC Group Web Performance and helped me develop several new insights into page performance that I could not get elsewhere. This tool embraces the best analysis features I developed in Toaster and puts the on the web for all to use. Toaster has now been made open source so I'll try to get a copy of it working on the web despite the fact I originally designed it for local webserver use on Windows so the transition may not be straightforward.
Design and Composition
Roaster is designed to be responsive to allow the test results to be viewed upon any device. A desktop is recommended however as the volume of results displayed will be much easier to consume; some of the tables are quite wide. I'll work on additional forms of presentation to make this easier in the future.
Both JavaScript and PHP are used to make Roaster. The WPT HAR file is downloaded and parsed to identify all of the pages tested and their objects.
Roaster makes use of existing tools to help produce and present the analyses, including:
The last-used WPT ID is stored in local storage for easy access.
Instructions
- Run a test in WebPageTest
- Copy the result link URL fromWebPageTest
- Paste the link into Roaster's "WPT ID" input box on the Home page and click "Read Results"
- For tests with more than 1 test, select the required page from the "Page" dropdown
Note there may be more than one page when:
- the test is a scripted test and has multiple steps
- testing comprised of more than 1 run
- both First View and Repeat tests were requested
- Navigate the various tabs to explore performance data
Hints and Tips
Help and Optimisation Boxes
I'll develop the boxes shown below the detailed display to show a variety of helpful hints about page and object composition and optimisation tips.
Row expansions
Table rows can be expanded (click an icon shown at either end of the row). Each table shows different details about the selected object when the row is expanded.
Objects
TBD
Headers
TBD
Images
JPEG, PNG, GIF and WEBP are read. SVG images are not shown at present - differentiating an SVG image from an SVG font is a little tricky.
Image Metadata
Image metadata will be read when the first page of results is shown or when the page is changed; note that it may take a few seconds for the metadata to be populated.
If you use the filter, for example to look for "JPEG" images, you may see some rows with "unread" metadata. Simply click the "Read Metadata" button to scan the images listed and to populate the remainder of the metadata.
Image View
Click "View" to view all the images listed in one go, at their natural size.


Description

public class IndexRoutingTable extends AbstractDiffable<IndexRoutingTable> implements java.lang.Iterable<IndexShardRoutingTable>
IndexRoutingTable
represents routing information for a single
index. The routing table maintains a list of all shards in the index. A
single shard in this context has one more instances namely exactly one
primary
and 1 or more replicas. In other
words, each instance of a shard is considered a replica while only one
replica per shard is a primary replica. The primary replica
can be seen as the "leader" of the shard acting as the primary entry point
for operations on a specific shard.
Note: The term replica is not directly
reflected in the routing table or in related classes, replicas are
represented as ShardRouting

 He is my favorite cat and also coincidently my only cat. That is quite convenient isn't it? My mom found him living in a gutter by railroad tracks near her job when he was only a month old. After she learned that her 9 year old cat and him would not get along, she gave me custody. I've loved him from the moment I saw him. Here's why:
- He is cute and adorable
- He speaks, almost too much
- He is fun to be around

Watch Bottas and Grosjean collide in FP2
by Joseph TyrrellIt looked as if FP2 in Abu Dhabi would be plain sailing for Mercedes and Valtteri Bottas, however, with 20 minutes left the Finn collided with Romain Grosjean. Bottas was able to get back out on track but the Frenchman's session came to an early end.
Bottas topped the opening two sessions at the Yas Marina Circuit as he looks for a fifth win of his best season in Formula 1. He'll have to do it from the back of the after taking a new engine.
Check out Bottas' crash with Grosjean in the clip below!
