THE LORD OF PENGERSWICK AN ENCHANTER.
THE Lord of Pengerswick came from some Eastern clime, bringing with him a foreign lady of great beauty. She was considered by all an "outlandish" woman; and by many declared to be a "Saracen." [a] No one, beyond the selected servants, was ever allowed within the walls of Pengerswick Castle; and they, it was said, were bound by magic spells. No one dared tell of anything transacted within the walls; consequently all. was conjecture amongst the neighbouring peasantry, miners, and fishermen. Certain it was, they said, that Pengerswick would shut himself up for days together in his chamber, burning strange things, which sent their strong odours,--not only to every part of the castle,--
but for miles around the country. Often at night, and especially in stormy weather, Pengerswick was heard for hours together calling up the spirits, by reading from his books in some unknown tongue. On those occasions his voice would roll through the halls louder than the surging waves which beat against the neighbouring rocks, the spirits replying like the roar of thunder. Then would all the servants rush in fright from the building, and remain crowded together, even in the most tempestuous night, in one of the open courts. Fearful indeed would be the strife between the man and the demons ; and it sometimes happened that the spirits were too powerful for the enchanter. He was, however, constantly and carefully watched by his wife; and whenever the strife became too serious, her harp was heard making the softest, the sweetest music. At this the spirits fled; and they were heard passing through the air towards the Land's-End, moaning like the soughing of a departing storm. The lights would then be extinguished in the enchanter's tower, and all would be peace. The servants would return to their apartments with a feeling of perfect confidence. They feared their master, but their mistress inspired them with love. Lady Pengerswick was never seen beyond the grounds surrounding the castle. She sat all day in lonely state and pride in her tower, the lattice-window of her apartment being high on the seaward side. Her voice accompanying the music of her harp was rarely heard, hut when she warbled the soft love strains of her Eastern land. Often at early dawn the very fishes of the neighbouring bay would raise their heads above the surface of the waters, enchanted by the music and the voice; and it is said that the mermaids from the Lizard, and many of the strange spirits of the waters, would come near to Pengerswick cove, drawn by the same influence. On moonlight nights the air has often seemed to be full of sound, and yet the lady's voice was seldom louder than that of a warbling bird. On these occasions, men have seen thousands of spirits gliding up and down the moonbeams, and floating idly on the silvered waves, listening to, and sometimes softly echoing, the words which Lady Pengerswick sang. Long did this strange pair inhabit this lonely castle; and although the Lord of Pengerswick frequently rode abroad on a most magnificent horse--which had the reputation of being of Satanic origin, it was at once so docile to its master and so wild to any other person,--yet he made no acquaintance with any of the neighbouring gentry. He was feared by all, and yet they respected him for many of the good deeds performed by him. He completely enthralled the Giants of the Mount; and before he disappeared from Cornwall, they died, owing, it was said, to grief and want of food.
Where the Lord of Pengerswick came from, no one knew; he, with his lady, with two attendants, who never spoke in any but an Eastern tongue, which was understood by none around them, made their appearance one winter's day, mounted on beautiful horses, evidently from Arabia or some distant land.
They soon--having gold in abundance--got possession of a cottage; and in a marvellously short time the castle, which yet bears his name, was rebuilt by this lord. Many affirm that the lord by the force of his enchantments, and the lady by the spell of her voice, compelled the spirits of the earth and air to work for them; and that three nights were sufficient to rear an enormous pile, of which but one tower now remains.
Their coming was sudden and mysterious; their going was still more so. Years had rolled on, and the people around were familiarised with those strange neighbours, from whom also they derived large profits, since they paid whatsoever price was demanded for any article which they required. One day a stranger was seen in Market-Jew, whose face was bronzed by long exposure to an Eastern sun. No one knew him; and he eluded the anxious inquiries of the numerous gossips, who were especially anxious to learn something of this man, who, it was surmised by every one, must have some connection with Pengerswick or his lady; yet no one could assign any reason for such a supposition. Week after week passed away, and the stranger remained in the town, giving no sign. Wonder was on every old woman's lips, and expressed in every old man's eyes; but they had to wonder on. One thing, it was said, had been noticed; and this seemed to confirm the suspicions of the people. The stranger wandered out on dark nights--spent them, it was thought on the sea-shore; and some fishermen said they had seen him seated on the rock at the entrance of the valley of Pengerswic'k. It was thought that the lord kept more at home than usual, and of late no one had heard his incantation songs and sounds; neither had they heard the harp of the lady. A very tempestuous night, singular for its gloom-- when even the ordinary light, which, on the darkest night, is evident to the traveller in the open country, it did not exist--appears to have brought things to their climax. There was a sudden alarm in Market-Jew, a red glare in the eastern sky, and presently a burst of flames above the hill, and St Michael's Mount was illuminated in a remarkable manner. Pengerswick Castle was on fire; the servants fled in terror; but neither the lord nor his lady could be found. From that day to the present they were lost to all.
The interior of the castle was entirely destroyed; not a vestige of furniture, books, or anything belonging to the "Enchanter" could be found. He and everything belonging to him had vanished, and, strange to tell, from that night the bronzed stranger was never again seen. The inhabitants of Market-Jew naturally crowded to the fire; and when all was over they returned to their homes, speculating on the strange occurrences of the night. Two of the oldest people always declared that, when the flames were at the highest, they saw two men and a lady floating in the midst of the lire, and that they ascended from amidst the falling walls, passed through the air like lightning, and disappeared.

Description
This is my personal website. It’s mainly intended for people that are already familiar with web development to showcase some of my work and skillsets in collaboration purposes.
Process
For this project I used Bootstrap grids, Jquery interactions and some custom Javascript for the moving background on the landing page. I mainly became static because of the server capabilities on this domain, but it’s fun working under some restrains.
Principles
Something that I had in mind when I designed the structure of the website was to develop a flow through the content. Aiming for a very linear experience while allowing the user to jump to the most interesting part right away. It also have highlighted words here and there to quickly direct the user to what I think is the more important things.


Just as with any other huddly device, the SDK can be used to upgrade and control the Huddly Canvas camera. This intelligent whiteboard camera is used to detect, dewarp and enhance the contents of a whiteboard automatically without any user input. The last feature, namely the "enhance" bit can be controlled using the SDK (meaning that it an be turned on and off). The detection and the dewarping of the whiteboard is a standard feature and therfore it can not be toggled.
In this docs page we will show you how to toggle the enhance feature of the Huddly Canvas camera using the SDK.
....
// We assume the sdk instance has already been initialized
....
const applicationTeardown = () => {
process.exit();
}
let canvasDevice;
sdk.on('ATTACH', (cameraManager) => {
canvasDevice = cameraManager;
canvasDevice.enableCanvasEnhanceMode()
.then(_ => new Promise((resolve, reject) => {
// Device requires reboot for us to see the changes on the camera live stream
canvasDevice.reboot()
.then(_ => {
console.log('Canvas enhancement mode enabled!');
resolve();
}).catch((e) => {
console.error('Something went wrong while rebooting the camera');
reject(e);
});
}))
.catch((e) => {
console.error('Something went wrong while disabling canvas ehancement mode!');
console.trace(e);

When used in sketches running on mobile devices, this widget will use the orientation of the device as a signal.
Example:
pwm = PWM()
o = Orientation()
pwm.frequency = o.X
pwm.amp = o.Y
pwm.pulsewidth = o.Z
start : Begin querying sensors for orientation data. Note: this is called automatically when Orientation is used with Gibber's mapping abstractions.
stop : End querying sensors for orientation data.
See the Widget prototype for relevant methods.

But there’s so much wrong with the act of checkbox testing. As part of a wider testing strategy, it does have its place. But it’s often seen a lot as being the only method of testing a new feature, and this is where the problem lies. Let me explain why. [Read more…]
In the last year or so, I realised that perhaps we might be relying on acceptance criteria too much. Doing so can be dangerous; it can easily lead to checkbox testing, and it can lead to the tester (and even the developer) not thinking at all. [Read more…]


Action Pack — On rails from request to response
Action Pack splits the response to a web request into a controller part (performing the logic) and a view part (rendering a template). This two-step approach is known as an action, which will normally create, read, update, or delete (CRUD for short) some sort of model part (often backed by a database) before choosing either to render a template or redirecting to another action.
Action Pack implements these actions as public methods on Action Controllers and uses Action Views to implement the template rendering. Action Controllers are then responsible for handling all the actions relating to a certain part of an application. This grouping usually consists of actions for lists and for CRUDs revolving around a single (or a few) model objects. So ContactController would be responsible for listing contacts, creating, deleting, and updating contacts. A WeblogController could be responsible for both posts and comments.
Action View templates are written using embedded Ruby in tags mingled in with the HTML. To avoid cluttering the templates with code, a bunch of helper classes provide common behavior for forms, dates, and strings. And it’s easy to add specific helpers to keep the separation as the application evolves.
Note: Some of the features, such as scaffolding and form building, are tied to ActiveRecord (an object-relational mapping package), but that doesn’t mean that Action Pack depends on Active Record. Action Pack is an independent package that can be used with any sort of backend (Instiki, which is based on an older version of Action Pack, used Madeleine for example). Read more about the role Action Pack can play when used together with Active Record on www.rubyonrails.org.
A short rundown of the major features:
- Actions grouped in controller as methods instead of separate command
objects and can therefore share helper methods.
BlogController < ActionController::Base def display @customer = find_customer end def update @customer = find_customer @customer.attributes = params[:customer] @customer.save ? redirect_to(:action => "display") : render(:action => "edit") end private def find_customer() Customer.find(params[:id]) end end
- Embedded Ruby for templates (no new "easy" template language)
<% for post in @posts %> Title: <%= post.title %> <% end %> All post titles: <%= @post.collect{ |p| p.title }.join ", " %> <% unless @person.is_client? %> Not for clients to see... <% end %>
- Builder-based templates (great for XML content, like RSS)
xml.rss("version" => "2.0") do xml.channel do xml.title(@feed_title) xml.link(@url) xml.description "Basecamp: Recent items" xml.language "en-us" xml.ttl "40" for item in @recent_items xml.item do xml.title(item_title(item)) xml.description(item_description(item)) xml.pubDate(item_pubDate(item)) xml.guid(@recent_items.url(item)) xml.link(@recent_items.url(item)) end end end end
- Filters for pre and post processing of the response (as methods, procs, and
classes)
class WeblogController < ActionController::Base before_filter :authenticate, :cache, :audit after_filter { |c| c.response.body = GZip::compress(c.response.body) } after_filter LocalizeFilter def list # Before this action is run, the user will be authenticated, the cache # will be examined to see if a valid copy of the results already # exists, and the action will be logged for auditing. # After this action has run, the output will first be localized then # compressed to minimize bandwidth usage end private def authenticate # Implement the filter with full access to both request and response end end
- Helpers for forms, dates, action links, and text
<%= text_field "post", "title", "size" => 30 %> <%= html_date_select(Date.today) %> <%= link_to "New post", :controller => "post", :action => "new" %> <%= truncate(post.title, 25) %>
- Layout sharing for template reuse (think simple version of Struts Tiles)
class WeblogController < ActionController::Base layout "weblog_layout" def hello_world end end Layout file (called weblog_layout): <%= @content_for_layout %> Template for hello_world action:
Hello world
 Result of running hello_world action:
Hello world

- Routing makes pretty urls incredibly easy
map.connect 'clients/:client_name/:project_name/:controller/:action' Accessing /clients/37signals/basecamp/project/dash calls ProjectController#dash with { "client_name" => "37signals", "project_name" => "basecamp" } in @params["params"] From that URL, you can rewrite the redirect in a number of ways: redirect_to(:action => "edit") => /clients/37signals/basecamp/project/dash redirect_to(:client_name => "nextangle", :project_name => "rails") => /clients/nextangle/rails/project/dash
- Javascript and Ajax integration.
link_to_function "Greeting", "alert('Hello world!')" link_to_remote "Delete this post", :update => "posts", :url => { :action => "destroy", :id => post.id }
- Pagination for navigating lists of results.
# controller def list @pages, @people = paginate :people, :order => 'last_name, first_name' end # view <%= link_to "Previous page", { :page => @pages.current.previous } if @pages.current.previous %> <%= link_to "Next page", { :page => @pages.current.next } if @pages.current.next %>
- Easy testing of both controller and template result through
TestRequest/Response
class LoginControllerTest < Test::Unit::TestCase def setup @controller = LoginController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new end def test_failing_authenticate process :authenticate, :user_name => "nop", :password => "" assert flash.has_key?(:alert) assert_redirected_to :action => "index" end end
- Automated benchmarking and integrated logging
Processing WeblogController#index (for <IP_ADDRESS> at Fri May 28 00:41:55) Parameters: {"action"=>"index", "controller"=>"weblog"} Rendering weblog/index (200 OK) Completed in 0.029281 (34 reqs/sec) If Active Record is used as the model, you'll have the database debugging as well: Processing WeblogController#create (for <IP_ADDRESS> at Sat Jun 19 14:04:23) Params: {"controller"=>"weblog", "action"=>"create", "post"=>{"title"=>"this is good"} } SQL (0.000627) INSERT INTO posts (title) VALUES('this is good') Redirected to http://test/weblog/display/5 Completed in 0.221764 (4 reqs/sec) | DB: 0.059920 (27%) You specify a logger through a class method, such as: ActionController::Base.logger = Logger.new("Application Log") ActionController::Base.logger = Log4r::Logger.new("Application Log")
- Caching at three levels of granularity (page, action, fragment)
class WeblogController < ActionController::Base caches_page :show caches_action :account def show # the output of the method will be cached as # ActionController::Base.page_cache_directory + "/weblog/show/n.html" # and the web server will pick it up without even hitting Rails end def account # the output of the method will be cached in the fragment store # but Rails is hit to retrieve it, so filters are run end def update List.update(params[:list][:id], params[:list]) expire_page :action => "show", :id => params[:list][:id] expire_action :action => "account" redirect_to :action => "show", :id => params[:list][:id] end end
- Component requests from one controller to another
class WeblogController < ActionController::Base # Performs a method and then lets hello_world output its render def delegate_action do_other_stuff_before_hello_world render_component :controller => "greeter", :action => "hello_world" end end class GreeterController < ActionController::Base def hello_world render_text "Hello World!" end end The same can be done in a view to do a partial rendering: Let's see a greeting: <%= render_component :controller => "greeter", :action => "hello_world" %>
- Powerful debugging mechanism for local requests
All exceptions raised on actions performed on the request of a local user will be presented with a tailored debugging screen that includes exception message, stack trace, request parameters, session contents, and the half-finished response.
- Scaffolding for Action Record model objects
require 'account' # must be an Active Record class class AccountController < ActionController::Base scaffold :account end The AccountController now has the full CRUD range of actions and default templates: list, show, destroy, new, create, edit, update
{Learn more}classes/ActionController/Scaffolding/ClassMethods.html
- Form building for Active Record model objects
The post object has a title (varchar), content (text), and written_on (date) <%= form "post" %> ...will generate something like (the selects will have more options, of course): <form action="create" method="POST">
 Title:
 <input type="text" name="post[title]" value="<%= @post.title %>" />

 Content:
 <textarea name="post[content]"><%= @post.title %></textarea>

 Written on:
 <select name='post[written_on(3i)]'><option>18</option></select> <select name='post[written_on(2i)]'><option value='7'>July</option></select> <select name='post[written_on(1i)]'><option>2004</option></select>
 <input type="submit" value="Create"> </form> This form generates a @params["post"] array that can be used directly in a save action: class WeblogController < ActionController::Base def save post = Post.create(params[:post]) redirect_to :action => "display", :id => post.id end end
- Runs on top of WEBrick, CGI, FCGI, and mod_ruby
Simple example
This example will implement a simple weblog system using inline templates and an Active Record model. So let’s build that WeblogController with just a few methods:
require 'action_controller' require 'post' class WeblogController < ActionController::Base layout "weblog/layout" def index @posts = Post.find_all end def display @post = Post.find(:params[:id]) end def new @post = Post.new end def create @post = Post.create(params[:post]) redirect_to :action => "display", :id => @post.id end end WeblogController::Base.template_root = File.dirname(__FILE__) WeblogController.process_cgi if $0 == __FILE__
The last two lines are responsible for telling ActionController where the template files are located and actually running the controller on a new request from the web-server (like to be Apache).
And the templates look like this:
weblog/layout.rhtml:  <%= @content_for_layout %>  weblog/index.rhtml: <% for post in @posts %>
<%= link_to(post.title, :action => "display", :id => post.id %>
 <% end %> weblog/display.rhtml:
 <%= post.title %>
 <%= post.content %>
 weblog/new.rhtml: <%= form "post" %>
This simple setup will list all the posts in the system on the index page, which is called by accessing /weblog/. It uses the form builder for the Active Record model to make the new screen, which in turn hands everything over to the create action (that’s the default target for the form builder when given a new model). After creating the post, it’ll redirect to the display page using an URL such as /weblog/display/5 (where 5 is the id of the post).
Examples
Action Pack ships with three examples that all demonstrate an increasingly detailed view of the possibilities. First is blog_controller that is just a single file for the whole MVC (but still split into separate parts). Second is the debate_controller that uses separate template files and multiple screens. Third is the address_book_controller that uses the layout feature to separate template casing from content.
Please note that you might need to change the "shebang" line to #!/usr/local/env ruby, if your Ruby is not placed in /usr/local/bin/ruby

If you have enjoyed learning from this article, below is a list of some recommended articles for you-


Java Assessment
Q1. Given the string “strawberries” saved in a variable called fruit, what would “fruit.substring(2, 5)” return?
- [ ] rawb
- [X] raw
- [ ] awb
- [ ] traw
Reasoning: The substring method is accepting two arugments. The first argument being the index to start(includes that char at 2) and the second the index of the string to end the substring(excludes the char at 5). Strings in Java are like arrays of chars. Therefore the method will return “raw” as those are the chars in indexs 2,3, and 4. You can also take the ending index and subtract the beginning index from it, to determine how many chars will be included in the substring (5-2=3).
Q2. How can you achieve runtime polymorphism in Java?
- [ ] method overloading

US Official Claims Russia Exploits Countries’ Security Requirements with S-400
Assistant Secretary of State for Political Military Affairs Clarke Cooper suggested on Thursday that Russia and China exploit other countries’ security requirements, calling the US the defence partner of choice.
Cooper spoke at the Meridian International Center, a Washington-based think-tank.
“Through the targeted marketing of systems like the S-400, Russia seeks to exploit the genuine security requirements of partners to create challenges in our ability — legal and technological — to provide them with the most advanced defensive capabilities,” he said.
Cooper identified China and Russia as strategic competitors whose efforts have led to the proliferation of arms around the world.
"We have come a long way since the AK-47 became the ubiquitous symbol of Soviet-backed insurgencies from Southeast Asia to Africa. Today, Russia is working hard to foist variants of its S-400 air defence system around the world, while China is supplying everything from armoured personnel carriers to armed drones.”
Cooper noted that it is the first time since the Cold War that the US started to lose global dominance in weapon sales, as many nations “look at partnering with America on matters of defence and security not as an imperative, but as one of several options.” The Bureau of Political Military Affairs, which Cooper heads as Assistant Secretary, is the State Department’s interface with the Defense Department, and oversees security assistance and Foreign Military Sales.


By the end of this course, you will have completed 4 homework assignments, all of which involve a substantial amount of programming. Each assignment can be submitted multiple times without penalty, so you can use feedback from the automatic grader to revise your code. Note that your most recent score will be recorded as your grade.
Homework assignments turned in between one minute and one week late will receive a penalty of 25%. An assignment that would have scored 100 points would only receive 75 points if it is submitted 2 days late. Assignments turned in more than a week late will receive no points, but will still receive feedback from the autograder.
In addition to the homework assignments, there will be 4 quizzes. You will have only one chance to take each quiz, with the exception of Quiz 0 (the diagnostic quiz). You may take Quiz 0 as many times as you want. All quizzes must be turned in by the end of the day on the due date (midnight of your local time). Late quizzes will receive 0 points.
Each of the 4 homework assignments will be worth 11% of the final grade.
The diagnostic quiz (Quiz 0) is not graded.
Quiz 1, Quiz 2, and Quiz 3 are worth 20%, 20% and 15% of the final grade, respectively.
To earn a certificate for this class you must achieve a score of at least 50% overall.

Style
OneUIUX comes with predefined themes for different color schemes.
OneUIUX comes with predefined css with different shades. You can access our demos and click on pallet icon at bottom right corner. Select color you like this color demo pallet require local host or hosting files somewhere. Also predefined css can be replaced in CSS in HTML head tag by just replacing stlysheet name.
Default white css file:
<link href="../assets/css/style-dark-blue.css" rel="stylesheet" id="style">
Other styles are:
style-amber.css
style-black.css
style-gray.css
style-maroon.css
style-blue.css

style-dark-brown.css
style-dark-gray.css
style-dark-green.css
style-dark-pink.css
style-dark-purple.css
We have also used color style picker you can utilize it for preview color scheme. If you are not using anymore style picker we recommend to remove code of stylepicker from page as class name with right sidebar and also remove 'color-scheme-demo.js' from page to reduce page load time. Make sure here to set style on reload we have used cookie js file to store variable for selected styles.
Scripts
We have added scripts template functionality and style functionality.
Here we are dividing three saperate custom js section.
Template level
All the script which are required into the template funationalities at global level are defined into the main.js into js folder
Color style
All the script which are required for color change and cookie variable storage are defined into the color-scheme-demo.js into js folder. Here specific demo has specific css and js demo specific in demo folder.
Page specific
All the script which are required for page specific elements are kept on page before enging of body tag.
Hope this helps to differentiate and well utilization of scripts while creative template
Code Structure
We have clean code with minimum comments and useful comments.
Here is minimal code sample to use for start new Mobile or app.

Software Engineer - Full-Stack Developer - Bootstrap Extraordinaire
I'm a software engineer with experience all over both the technological and geographical maps. My background includes work in the full .NET web stack, a node.js web app, various scripting languages, and a Universal Windows native app. Born and currently living in Kentucky, I'm interested in moving west and working for a technology company.
 I would love to work in a full-on Agile or DevOps environment.
I also love to run and bike. I believe that bicycle-based transportation can help solve many of our infrastructural and economical problems.
Thanks for your time, and I hope to hear from you.


Tah is a Bluetooth Low Energy open source development platform compatible with the Arduino.
Tah has onboard BLE (Bluetooth 4.0) and can be used with XBee networks to increase the range from 100m to 300m. Tah can be used as a bridge between Smart phone and XBee network.
With this feature of Tah the user can send commands and receives data over the XBee network and control and develope any wireless sensor network and access it with smart phone.
This tutorial is divided into two major parts first one Tah transmitter section and other is receiver on the Robot which will control the motions of robot.
Let's configure the XBee radios. Using a serial connection, program the two XBee radios to talk to each other at 9600 baud. You can use a program like HyperTerm or CoolTerm in Windows. Similarly for Linux you can use Minicom to configure the XBee radios.
This demo uses the default PAN ID of 3332, but you should choose a different one so that other XBee radios in the area do not interfere with your communications. For the first XBee, use the +++ sequence to go into command mode. You should receive an OK message back. Then issue this command:
ATID3332, ATMY10, ATDL11, ATBD3, ATWR, ATCN
Now you have configured the first XBee radio as PANID 3332, ATMY10 (16-bit source address), ATDL11 (Destination Low Address), ATBD3(9600 baud rate) and to confirm settings use ATWR and exit from command mode use ATCN.
Now configure the second XBee. Connect your second XBee and again use the +++ sequence to go into command mode. Then issue this command:
ATID3332, ATMY11, ATDL10, ATBD3, ATWR, ATCN
The only difference here is that for the second XBee, you set the destination address to 10 and the source address to 11. The two XBees are now configured to talk to each other.
In this demo we have implemented the Duplex communication in two XBee radios and sending data or commands from a smartphone using the Tah Write app.
We are controlling onboard LEDs of Tah used in XBee network using smartphone. Here Tah has onboard BLE so Tah is acting as a communication bridge between Xbee and Smart phone.
In this demo command 1 is send from smart phone to Tah and Tah communicate to XBee and XBee coordinator wil send that data to End device of XBee, similarly End device will again send acknowledge signal to coordinator and LEDs will blink and vice versa.
We are using Software Serial for XBee connections on Tah pin 8 is Rx and pin 9 is Tx of XBee.
You will also receive a notification from remote XBee on your phone.

Conditional Statements
Prerequisites
- Welcome Quest
- Power of Puppet Quest
- Resources Quest
- Mainfest Quest
- Classes Quest
- Variables Quest
Quest Objectives
- Learn how to use conditional logic to make your manifests adaptable.
- Understand the syntax and function of the
if
,unless
,case
, andselector
statements.
Getting Started
Conditional statements allow you to write Puppet code that will return different values or execute different blocks of code depending on the conditions you specify. This, in conjunction with Facter facts, will enable you to write Puppet code that accomodates different platforms, operating systems, and functional requirements.
To start this quest enter the following command:
quest --start conditionals
Conditions
Just dropped in (to see what condition my condition was in)
-Mickey Newbury
Conditional statements let your Puppet code behave differently in different situations. They are most helpful when combined with facts or with data pertaining to the systems. This enables you to write code to perform as desired on a variety of operating systems and under differing system conditions. Pretty neat, don't you think?
Puppet supports a few different ways of implementing conditional logic:
-
if
statements -
unless
statements - case statements, and
- selectors
The 'if' Statement
Puppet’s if
statements behave much like those in many other programming and scripting languages.
An if
statement includes a condition followed by a block of Puppet code that will only be executed if that condition evaluates as true. Optionally, an if
statement can also include any number of elsif
clauses and an else
clause. Here are some rules:
- If the
if
condition fails, Puppet moves on to theelsif
condition (if one exists) - If both the
if
andelsif
conditions fail, Puppet will execute the code in theelse
clause (if one exists) - If all the conditions fail, and there is no
else
block, Puppet will do nothing and move on
The following is an example of an if
statement you might use to raise a warning when a class is included on an unsupported system:
if $is_virtual == 'true' {
# Our NTP module is not supported on virtual machines:
warn( 'Tried to include class ntp on virtual machine.' )
}
elsif $operatingsystem == 'Darwin' {
# Our NTP module is not supported on Darwin:
warn( 'This NTP module does not yet work on Darwin.' )
}
else {
# Normal node, include the class.
include ntp
}
The Warn Function
The warn()
function will not affect the execution of the rest of the manifest, but if you were running Puppet in the usual Master-Agent setup, it would log a message on the server at the 'warn' level.
Task 1 :
Just as we have done in the Variables Quest, let's create a manifest and add a simple conditional statement. The file should report on how long the VM has been up and running.
nano ~/conditionals.pp
Enter the following code into your conditionals.pp
manifest:
if $::uptime_hours < 2 {
$myuptime = "Uptime is less than two hours.\n"
}
elsif $::uptime_hours < 5 {
$myuptime = "Uptime is less than five hours.\n"
}
else {
$myuptime = "Uptime is greater than four hours.\n"
}
file {'/root/conditionals.txt':
ensure => present,
content => $myuptime,
}
Use the puppet parser
tool to check your syntax, then simulate the change in --noop
mode without enforcing it. If the noop looks good, enforce the conditionals.pp
manifest using the puppet apply
tool.
Have a look at the conditionals.txt
file using the cat
command.
Task 2 :
Use the command facter uptime_hours
to check the uptime yourself. The notice you saw when you applied your manifest should describe the uptime returned from the Facter tool.
The 'unless' Statement
The unless
statement works like a reversed if
statement. An unless
statements takes a condition and a block of Puppet code. It will only execute the block if the condition is false. If the condition is true, Puppet will do nothing and move on. Note that there is no equivalent of elsif
or else
clauses for unless
statements.
The 'case' Statement
Like if
statements, case statements choose one of several blocks of Puppet code to execute. Case statements take a control expression, a list of cases, and a series of Puppet code blocks that correspond to those cases. Puppet will execute the first block of code whose case value matches the control expression.
- Basic cases are compared with the
==
operator (which is case-insensitive). - Regular expression cases are compared with the
=~
operator (which is case-sensitive). - The special
default
case matches anything. It should always be included at the end of a case statement to catch anything that did not match an explicit case.
Task 3 :
Create a case.pp
manifest with the following conditional statement and file
resource declaration.
case $::operatingsystem {
'CentOS': { $apache_pkg = 'httpd' }
'Redhat': { $apache_pkg = 'httpd' }
'Debian': { $apache_pkg = 'apache2' }
'Ubuntu': { $apache_pkg = 'apache2' }
default: { fail("Unrecognized operating system for webserver") }
}
file {'/root/case.txt':
ensure => present,
content => "Apache package name: ${apache_pkg}\n"
}
When you've validated your syntax and run a --noop
, apply the manifest:
puppet apply case.pp
Use the cat
command to inspect the case.txt
file. Because the Learning VM is running CentOS, you will see that the selected Apache package name is 'httpd'.
For the sake of simplicity, we've output the result of the case statement to a file, but keep in mind that in an actual practice, instead of using the result of the case statement like the one above to define the contents of a file, you could use it directly in a package
resource declaration like the following:
package { $apache_pkg :
ensure => present,
}
This would allow you to always install and manage the right Apache package for a machine's operating system. This kind of careful accounting for different the conditions under which a manifest might run is an important part of writing flexible and re-usable Puppet code. It is a paradigm you will encounter frequently in published Puppet modules.
Also note that Puppet will choose the appropriate provider for the package depending on the operating system, without you have to mention it. On Debian-based systems, for example, it may use apt
and on RedHat systems, it will use yum
.
The 'selector' Statement
Selector statements are very similar to case
statements, but instead of executing a block of code, a selector assigns a value directly. A selector might look something like this:
$rootgroup = $::osfamily ? {
'Solaris' => 'wheel',
'Darwin' => 'wheel',
'FreeBSD' => 'wheel',
'default' => 'root',
}
Here, the value of the $rootgroup
is determined based on the control variable $osfamily
. Following the control variable is a ?
(question mark) keyword. In the block surrounded by curly braces are series of possible values for the $::osfamily fact, followed by the value that the selector should return if the value matches the control variable.
Because a selector can only return a value and cannot execute a function like fail()
or warn()
, it is up to you to make sure your code handles unexpected conditions gracefully. You wouldn't want Puppet to forge ahead with with an inappropriate default value and encounter errors down the line.
Task 4 :
By writing a Puppet manifest that uses a selector, create a file /root/architecture.txt
that lists whether the VM is a 64-bit or a 32-bit machine.
To accomplish this, create a file in the root directory, called architecture.pp
:
nano architecture.pp
We know that i386 machines have a 32-bit architecture, and x86_64 machines have a 64-bit architecture. Let's set the content of the file based on this fact:
file { '/root/architecture.txt' :
ensure => file,
content => $::architecture ? {
'i386' => "This machine has a 32-bit architecture.\n",
'x86_64' => "This machine has a 64-bit architecture.\n",
}
}
See what we did here? Instead of having the selector return a value and saving it in a variable, as we did in the previous example with $rootgroup
, we use it to specify the value of the content
attribute in-line.
Once you have created the manifest, check the syntax and apply it.
Inspect the contents of the /root/architecture.txt
file to ensure that the content is what you expect.
Before you move on
We have discussed some intense information in the Variables Quest and this Quest. The information contained in all the quests to this point have guided you in creating flexible manifests. Should you not understand any of the topics previously discussed, we highly encourage you to revisit those quests before moving on to the Resource Ordering Quest.


İslamic Morality
The Muslim person takes care not to harm people, animals, plants and even inanimate beings with good health by reflecting the peace and beauty in his heart to his environment.
In any case, one should stay away from the things that will disturb someone else. Polluting gardens, roads, countryside, waters, air and natural landscapes, throwing trash and dirt on the ground is unbecoming to the honor and dignity of humanity. The Muslim person thinks that someone else will be disturbed from the polluted place and that the beauty of the environment will deteriorate. He/She doesn't throw the pollutants such as kernels, nuts, peanut shells, bottles, canned boxes, papers packages waste and cigarette stub into the streets or picnic places on the contray, he throws them in the trash when he sees them. This is a requirement of perfecting faith. Because the Prophet (peace be upon him) had accepted the abolition of something that disturbed people as a branch of faith. And told people that he did not like those who persecuted people.
İbrahim Ersoylu
Translation: Zeynep Göver


Just because you can make a decision or solve a problem does not mean you should. There are times when it’s better to delay until the last possible moment, others when its best to go half way and stop, and of course times when action must be taken immediately. Recognizing the best way to handle any given situation is fundamental when handling large numbers of problems. Recently I’ve been working with a client on defining a change management process for a large system and have been thinking about these issues.
Not all problems are equal some are more urgent that others. In large systems problems can spawn other problems and often have complex relationships with each other. It is usually possible to draw a hierarchy of problems, more fundamental problems rise to the top, and less severe symptomatic problems fall to the bottom. Choosing whether to resolve a problem or ignore it depends on its relative urgency and degree of subservience within the problem hierarchy. These issues have little to do with the problem itself, they are outside the scope of the problem and are more correctly thought of as the meta-problem or problem context. Understanding the context of a problem is vitally important. The same problem in different contexts may have radically different solutions.
This process flow diagram shows a generic problem resolution process. For this discussion the important features are the parallelization of problem definition and problem context definition and the separation of candidate solution evaluation and candidate solution selection.
Parallelization of Problem Context Definition and Problem Definition
By understanding the context of a problem it is possible to make decisions about its resolution without actually understanding much about the problem itself. The two primary pieces of information needed to understand a problems context are its relative urgency and the degree to which it is subservient to other problems. An isolated problem that is unrelated to any other problem can only be resolved by a direct attack. Whereas a problem that is merely a symptom of some deeper, more fundamental problem can be resolved either by a direct attack or by resolving the more fundamental problem.
Keeping your Options Open
Retaining the option to solve a problem using any candidate solution for as long as possible has significant advantages. Most importantly the ability to learn from mistakes and hard won experience is preserved. If the opportunity arises solutions to more fundamental problems can be implemented instead, thus reducing total costs and wasted effort while increasing quality. And resources can be committed to more urgent problems if the relative urgency changes or new urgent problems arise.
Although tempting, there is often no pressing need to select a candidate solution. In the absence of such a pressing need it is better to wait. Large systems are typically dynamic, new problems occur all the time and existing problems morph as more is learned about them. In such an environment retaining the ability to change your mind for as long as possible is highly desirable since a better overall solution may be discovered. If however a candidate solution has been selected then decisions can and should be made on the assumption that the selected candidate solution will be implemented. It is my experience that too many system designers select candidate solutions when there is no pressing need. This boxes the designer in, reducing thier options and forces them along paths that may reduce overall quality unnecessarily.
This table recommends an approach for solution definition and development based on an evaluation of a problems context in two dimensions; relative urgency, and degree of likely subservience to other problems.
| Low Urgency | Medium Urgency | High Urgency | |
|---|---|---|---|
| High Subservience | Ignore the problem. It will go away when the more fundamental problem, to which this problem is subservient, is resolved. | Solve the more fundamental problem to which this problem is subservient. | Implement the easiest candidate solution available. Expect this temporary solution to be replaced when the more fundamental problem is resolved. |
| Medium Subservience | Solve the more fundamental problem to which this problem is subservient. | Evaluate candidate solutions then wait until the last moment before selecting one. Keep looking to solve a more fundamental problem while waiting. | Select a candidate solution but do not develop it until the last moment. Keep looking to solve a more fundamental problem while waiting. |
| Low Subservience | Select a solution but do not develop it until there is nothing more urgent to do or its urgency increases. | Select a candidate solution but do not develop it until the last moment. Retain the option to do something more important for as long as possible | Implement the cleanest candidate solution you can in the time available |

SECOND BEST A film review by Steve Rhodes Copyright 1995 Steve Rhodes
RATING (0 TO ****): ** 1/2
SECOND BEST is about a 42-year old Welsh man (William Hurt) who has never been married and has hardly ever even had a girlfriend.
 As promised, this boy is troubled. He comes from a LORD OF THE FLIES sort of past, and his Dad (Keith Allen), whom he loves dearly, has been in prison for a long time. He and his Dad made a pact, before his Dad left to go to prison, to love each other more than anyone else forever.
The show happens as much in the past as in the present and tells not only the boy's past but Hurt's as well. The interest in the show is provided by Hurt's character more than the boy's although the script was written, I think, to have the movie center around the boy.
Hurt plays a repressed man who looks at the world as if he is scared to venture into it. The scenes where the boys trashes his house and he just stares without speaking were a bit much even for his withdrawn character. I did not buy these scenes. On the whole though, Hurt plays it very convincingly, and you feel really sorry for him.
The main problem in the show for me was the casting of the boy. He was supposed to be an enigma, but he carried it overboard. During most of the movie it was hard to understand anything at all about what the boy was feeling and hence hard to empathize with him. The director (Chris Menges) should have realized this and given him better guidance.
All of the minor characters were quite good except the role played by John Hurt (no relation to William) which seemed to be out of another movie. My favorite minor character was Jane Horrocks's portrayal of the social worker. She was the only funny character in the movie and every one of her lines was a riot. I wish her part had been made larger. Given that everyone loved her in LIFE IS SWEET whereas I hated her in it, I was surprised myself at how enchanted I was with her acting in SECOND BEST.
Just watching the movie may make you want to move to the serenity of Wales - lovely cinematography (Ashley Rowe). On the other hand, it may scare you away from ever adopting a troubled child. A lot of the movie was either sad or disturbing because of the subject matter.
The movie runs 1:45 and is rated PG-13 for self-inflicted bloody wounds and some frightening subject matter. I think it would be okay for mature teenagers. I recommend this serious movie to you and give ** 1/2.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

Google begins rolling out Pixel 4-like ‘compact’ Assistant to older phones
Source: Joe Maring / Android Central
What you need to know
- Google has started rolling out a more compact version of the Assistant to older phones.
- So far, it appears only Pixel 3 and 3 XL owners have received the minor Assistant upgrade.
- While the "new" Assistant no longer takes up the entire screen, it doesn't offer the same look and not does it support all the new features.
With its latest Pixel 4 series phones, Google introduced the new Assistant with some major design improvements as well as many new capabilities. Google is now bringing (via 9to5Google) a more compact version of the Assistant to older phones. So far, the more compact Assistant upgrade has only been rolled to the Pixel 3 and Pixel 3 XL phones.
The new Assistant version that has started rolling out to older phones doesn't take up the entire screen real estate when displaying an answer. It only occupies as much space as required to display an answer. Apart from this change, however, the upgrade doesn't offer any of the other key features that the Pixel 4's new Assistant brings to the table.
It lacks support for continued conversation and screen context features are missing as well. And while the UI has been slightly tweaked, it doesn't match the new look found in the Assistant on the Pixel 4. At this point, it remains to be seen if Google will be rolling out a similar Assistant upgrade for the Pixel 2 series phones. The original Pixel phones, on the other hand, are unlikely to get the compact Google Assistant.
The new Assistant on the Pixel 4 series phones is claimed to be up to ten times faster than the older version, although it only speaks English currently and doesn't work without gesture navigation.

Nyzo version 618 (commit on GitHub) adds transaction indexing for the client.
This version does not affect any run modes. The functionality implemented will be used by the client in a future version.
When using the Nyzo blockchain for general data storage, the ability to index and efficiently search for transactions is necessary. This version adds simple transaction indexing and retrieval. In a future version, this functionality will be activated and wired into the client's transaction-search command. The Nyzo Chrome extension will then be able to use the API version of this command to efficiently retrieve, among other data, game states.
So, this version is just a step to playing Falken's Maze (well, actually, tic-tac-toe first) on Nyzo.
The TransactionIndexer class implements indexing. A preference is provided to allow indexing to be disabled. A subdirectory of the Nyzo data root directory stores the index files. Constants are defined for the byte size of an index entry and the maximum number of transactions that will be returned in a single query.
The TransactionIndexer.indexTransactionsForBlock() method implements indexing at the top level. All standard transactions in a block are indexed for both the sender and receiver. The transactions are first written to a file containing a list of all transactions sent or received by an account. Then, an index entry is written referencing the list entry. The ordering of these writes is important. Each file is written in a manner that is effectively atomic, and writing the list entry first ensures that no index entries reference missing list entries, regardless of when the process might be interrupted.
The TransactionIndexer.transactionsForAccount() method implements retrieval. Currently, this method returns only the newest transactions in an account, up to the limit of 100. Transaction selection is performed on the index file. Then, the transactions are retrieved from the list file using the offsets provided by the index file. This method will evolve to provide paging, searching on timestamp and block ranges, and filtering on sender-data prefixes.
Exceptions are logged, and the shorthand safeClose() method is used to ensure that the files are properly closed.
The TransactionIndexer.writeTransactionToList() method appends the bytes of a Transaction object to the end of the specified list file.
The TransactionIndexer.writeTransactionToIndex() method is slightly more complex. To keep the index entries in order on ascending timestamp without requiring indexing to be performed in order, the index file is rewritten to a temporary file, inserting the index entry at the appropriate point. This conserves memory, because it reads and writes only a single entry at a time.
The safeClose() method is used to ensure that the files are properly closed, and the temporary file is moved atomically to replace the previous index file. This ensures that the worst case of an abruptly terminated indexing operation would be a single orphan entry in the transaction list file, and there are no situations that would result in a corrupt index file.
Exceptions are logged, and a special case is provided for the first index entry in the file.
The TransactionIndexer.listFileForAccount() and TransactionIndexer.indexFileForAccount() methods provide consistent paths for their respective files.
The TransactionIndexer.transactionIndexEntry() method serializes some data useful for transaction lookup into a fixed-width entry. The fixed-width entry, combined with ordering on timestamp, will allow easy binary searches to find start and end indices for searches limited on timestamp or block-height ranges.
The TransactionIndexer.safeClose() method is used to improve readability of other methods.
The TransactionIndexerTest was added to the test suite. We now ensure these tests complete successfully before each code release, and we are working to improve test coverage.
The remainder of additions in this version are in TransactionIndexerTest. This is a typical implementation of the NyzoTest interface. A main() method allows this test class to be run individually.
The TransactionIndexerTest.run() method is the top level of the test. Java reflection is used to get the paths of some files used internally by TransactionIndexer. The files are deleted to make the test idempotent.
A set of test transactions is created and indexed. The content of the list files for the accounts is checked. The content of the index files is checked. Finally, the transaction lookup is checked.
A small set of absurd transactions is created. These are wrapped in a block and indexed.  If any validation logic were applied, the transactions would all be removed before indexing. When logic is able to handle unreasonable values, however, testing such unreasonable values can be useful for better understanding the logic's behavior in extreme cases.
The TransactionIndexerTest.checkIndexFile() method sorts the input transactions to ensure proper ordering in the index file. The timestamp and amount are checked.
The sender data is checked, and the sender byte (sender/receiver) is checked. The file offset is not yet checked. Any exception also results in test failure.
In TransactionIndexerTest.checkListFile(), the bytes of all transactions are checked in the order they were added.
The TransactionIndexerTest.checkTransactionLookup() method retrieves transactions using the public TransactionIndexer.transactionsForAccount() method. The size of the retrieved set is checked.
The type (2: standard transaction) is checked. The timestamp, amount, and sender identifier are checked.
The receiver identifier and previous-hash height are checked. The previous-block hash of the input and output transactions are checked separately, and this field is not expected to be the same on output as on input.
The sender data and signature are checked.
The getFailureCause() method is implemented as required by the NyzoTest interface.

Collier County middle school student charged with making threat at school

Indonesia arrests dozens after IS-linked suicide bombing
JAKARTA: Dozens of suspected Indonesian militants have been rounded up after a suicide bomber linked to the Islamic State group killed himself and wounded six others in a police station attack last week, police said Monday (Nov 18).
About 45 suspects have been arrested since the Wednesday bombing in Medan on Sumatra island, while two bombmakers were shot dead during a raid, according to authorities.
"The pair resisted arrest and tried to attack police with sharp weapons and an air gun," National Police spokesman Dedi Prasetyo told reporters in Jakarta on Monday.
They had built a low-intensity bomb that the 24-year-old attacker strapped around his body, Prasetyo added.
Authorities had earlier said they suspected the bomber was a "lone wolf", following the blast that wounded four police officers and two civilians.

Police stations are frequent targets for radicals in the world's biggest Muslim-majority nation, which has long struggled with Islamist militancy.
About 20 other suspects arrested since the bombing - including the bomber's wife and the couple's religious mentor - played what police described as direct roles in the attack and had links to Jamaah Ansharut Daulah (JAD).
The outfit is a local extremist group that has pledged allegiance to IS and carried out previous attacks, including suicide bombings at several churches last year that killed a dozen congregants.
"The wife together with her husband (the bomber) were members of the JAD network," Prasetyo said.
"They had also attended military camp training... and were taught how to buy guns and sharp weapons," he added.

On Monday, some residents in Medan protested plans to bury the bomber's body in their city.
The police station attack was revenge for earlier militant arrests by Indonesia's elite anti-terror squad Densus 88, Prasetyo said.
Last month, President Joko Widodo ordered beefed-up security after two JAD-linked militants stabbed his chief security minister, who survived the attack.
The Southeast Asian nation of some 260 million has significant numbers of religious minorities - including Christians, Hindus and Buddhists - who have been targeted by radical Islamist groups amid concerns about rising intolerance.
