Police prevent looting at Mahikeng mall following blaze
by Ntwaagae SelekaNorth West police prevented a crowd of people from looting shops in Mahikeng on Monday morning, following a fire at a mall.
Police spokesperson Brigadier Sabata Mokgwabone said they had received a call that the group wanted to loot after one of the shops at a complex went up in flames around 06:00 on Monday.
The fire has since spread to other business outlets nearby.
"So far, we have been informed that the fire started at one of the shops and has spread to neighbouring shops. A crowd of people who were nearby attempted to loot some shops close to the one that was burning.
"Our members reacted quickly and chased them away. At the moment, the fire has spread and we don't know how many shops have been affected. We don't know how many shops have been burnt and are monitoring the situation and will ensure that there is no crime taking place there until the fire has been extinguished," said Mokgwabone.
The 2018/2019 National Crime Statistics show that looting or malicious damage to property increased by 1.4% (1 597) cases, from the previous year.

BEYOND RANGOON A film review by Michael John Legeros Copyright 1995 Michael John Legeros
(Columbia) Directed by John Boorman Written by Alex Lasker & Bill Rubenstein Cast Patricia Arquette, Frances McDormand, Spalding Gray, U Aung Ko MPAA Rating Rated "R" (presumably for graphic violence) Running Time Approx. 100 minutes Reviewed at General Cinemas at Pleasant Valley, Raleigh (22AUG95)
We could paraphrase Michelle Pfieffer's character in DANGEROUS MINDS and say that BEYOND RANGOON starts with an "A." That's fair enough. All movies, like all school children, should be given the benefit of the doubt. The chance to succeed. After all, we like to think that the right combination of talent and effort can do wonders. Mountains can be moved, and good movies can be made. Yeah right. Children fail, as do films. As does director John Boorman's latest.
The success of BEYOND RANGOON hinges on the believability of Patricia Arquette (ED WOOD, TRUE ROMANCE) as the busty Westerner-in-peril wandering about 1988 Burma without a passport. Though we can stomach the mild plot contrivances that get her there, it's a tougher task to overlook the actress. She's a lightweight. As the first scene (with narration!) demonstrates, she doesn't have *nearly* enough range for the emotions that her character--a mother fleeing the memories of a murdered husband and son--is supposed to show. She may give a stronger performance than, say, Keanu Reeves in A WALK IN THE CLOUDS, by not by much.
BEYOND RANGOON is a very physically appealing film, thanks to the practiced craftsmanship of John Boorman (DELIVERANCE, EXCALIBUR, HOPE AND GLORY). He keeps the narrative moving, no matter how muddy the story--or the heroine--gets. Why he chose Arquette remains a mystery, though. Maybe he was thinking that the dramatic weight of the story would overcome any casting deficiencies. But even after an hour of half-stated political statements and murky mass killings, we *still* don't know enough of what's happening in this country to feel distressed for the characters or their situations. Empty exoticism.
The technical credits in BEYOND RANGOON are a curious mix, combining lush jungle photography with bad blue-screen work. Also odd is the obvious dubbing. Done to make some of the foreign characters sound less foreign? And, is it my mistake, or do the same extras keep reappearing as different soldiers?? Doo doo doo doo. ["Twilight Zone" theme, or opinion of movie. You be the judge.]

Anthony Joshua 'loses £10k' in training camp bet ahead of Andy Ruiz Jr rematch
Video shows Joshua's training camp in relaxed mood ahead of Ruiz Jr clash after Brit bet pal Jonathan Constant £10,000 he couldn't complete 25 wide-grip pull-ups
by Gareth BicknellAnthony Joshua will go into his rematch against Andy Ruiz Jr £10,000 lighter after losing a bet with training-camp team member Jonathan Constant.
Joshua will bid to win back his back his WBA, IBF and WBO heavyweight titles when he meets Ruiz Jr for a second time in Saudi Arabia on December 7.
Ruiz Jr pulled off one of the biggest shocks in boxing history when he stopped Joshua back in June after knocking the Brit down four times.
But Joshua's team looked in relaxed mood in a video posted from their training camp, which showed Constant trying to complete 25 wide-grip pull-ups in response to a challenge from the former Olympic boxing champ.
According to a tweet posted by TalkSport's online boxing editor Michael Benson, Joshua didn't believe that his friend and backroom team member Constant could complete the quarter-century of pull-ups - and bet him £10,000 he couldn't rise to the challenge.
After The Bell: Watch Mirror Fighting's new boxing show
Mirror Fighting has launched a new weekly boxing show in association with Betfair in which we analyse the latest big fights, play matchmaker, and preview forthcoming bouts.
Former super-middleweight world champion George Groves provides expert analysis.
To watch the latest show in full, click here.
The video shows Constant sail through the pull-ups at first, before tiring and then putting in a herculean effort to complete the 25th rep with the massive cash prize at stake.
After successfully completing the challenge, he can be seen being congratulated by team members while Joshua laughs, with cheers heard in the background.
Twitter users responded to the video saying the camp looked in happy and confident mood ahead of next week's huge rematch.
And Joshua himself is feeling confident ahead of the bout.
The 30-year-old told Sky Sports : "Apparently I'm fighting the quickest hands and the best fighter in the division. So once I beat him I want everybody to bow to me.
"I'm confident that I know what I need to do now, and I've prepared to the best of my capability to go out and perform. Performance leads to the win."

-
Each page should accomplish one store or piece of
functionality.
Some examples:
-
Allow the user to log in (
user_login.erl
). -
Change the user's preferences. (
user_preferences.erl
) -
Display a list of items. (
items_view.erl
) -
Allow the user to edit an item. (
items_edit.erl
)
-
Allow the user to log in (
16 Dynamic Routes Explained
16.1 Nitrogen Pages
16.1.1 Dynamic Routing Explained
Dynamic routing rules:
-
If there is an extension, assume a static file.
http://localhost:8000/routes/to/a/module http://localhost:8000/routes/to/a/static/file.html
-
Root page maps to
index.erl
-
Replaces slashes with underscores.
http://localhost:8000/routes/to/a/module -> routes_to_a_module.erl
-
Try the longest matching module.
http://localhost:8000/routes/to/a/module/foo/bar -> routes_to_a_module.erl
-
Modules that aren't found go to
web_404.erl
if it exists. - Static files that aren't found are handled by the underlying platform (not yet generalized.)
17 Creating a New Page
17.1 Nitrogen Pages
17.1.1 Exercise: Create a New Page
-
Generate the Page
bin/dev page my\_page $EDIT site/src/my\_page.erl
-
Replace the default body with:
body() -> "Hello World!".
-
Remove the
event/1
function. -
Compile the page and load
http://localhost:8080/my/page
18 How is a Page Rendered (Simple Version)
18.1 Nitrogen Pages
18.1.1 How is a Page Rendered?
- User hits a URL.
- URL is mapped to a module.
-
Nitrogen framework calls
module:main()
-
module:main()
calls a#template
-
#template
calls back into the page (or other modules) - Nitrogen framework renders the output into HTML/Javascript.
(This is the simple version. Complex version will come later.)
19 Anatomy of a Template
19.1 Nitrogen Pages
19.1.1 Anatomy of a Template
- HTML. The Page is slurped into the Template.
-
Contains one or more callouts, ie:
[[[module:body()]]]
-
Contains a script callout for Javascript:
[[[script]]]
-
The callouts look like Erlang, but they are not. They can only be
of the form
module:function(Args)
. The 'page' module refers to the current page.
20 Experimenting With Templates
20.1 Nitrogen Pages
20.1.1 Experimenting With Templates
-
Change the callout from
page:body()
topage:body1()
in the default template and reload the page. What happens? - Create another callout. What happens?
-
What happens when you change
page
to be a specific module? - Replace the module call with some arbitrary Erlang code. What happens?
21 PART 3 AGENDA
21.1 Nitrogen Elements
- What is a Nitrogen Element?
- Add Elements to Your Page
- Nested Elements
- Documentation
- Anatomy of a Nitrogen Element
22 What is a Nitrogen Element?
22.1 Nitrogen Elements
22.1.1 What is a Nitrogen Element?
An element can be either HTML, or some record that renders into HTML.
Change this:
body() -> "Hello World!".
To this:
body() -> #label { text="Hello World!"
The #label{}
element is rendered into:
<label class="wfid_tempNNNNN label">Hello World!</label>
View the rendered page source in your browser and search for "Hello World".
24 Nitrogen Element Properties
24.1 Nitrogen Elements
24.1.1 Why Nitrogen Elements?
Nitrogen elements serve two purposes:
-
Allow you to generate HTML within Erlang:
- Avoid mixing languages == clearer code.
- Fewer characters to type.
- Checked at compile time.
-
Abstraction layer:
- Avoid repeating common functionality.
- Hide complexity in a module.
25 Nitrogen Element Examples
25.1 Nitrogen Elements
25.1.1 Nitrogen Element Examples
Try this on my_page.erl:
body() -> [ #h1 { text="My Simple Application" }, #label { text="What is your name?" }, #textbox { }, #button { text="Submit" } ].
Then compile, reload, and view source.
26 Nested Elements
26.1 Nitrogen Elements
26.1.1 Nested Elements
Try a nested element:
body() -> #panel { style="margin: 50px;", body=[ #h1 { text="My Page" }, #label { text="Enter Your Name:" }, #textbox { }, #button { text="Submit" } ]}.
27 PART 4 AGENDA
27.1 Nitrogen Actions
- What is a Nitrogen Action?
- Wiring an Action
-
Conditional Actions with
#event{}
- Postbacks
28 What is a Nitrogen Action?
28.1 Nitrogen Actions
28.1.1 What is a Nitrogen Action?
An action can either be Javascript, or some record that renders into Javascript.
Add a Javascript alert to the #button{}
element. Then recompile
and run. What do you expect will happen?
body() -> [ #button { text="Submit", actions="alert('hello');" } ].
29 What is a Nitrogen Action?
29.1 Nitrogen Actions
29.1.1 What is a Nitrogen Action?
Do the same thing a different way.
body() -> [ #button { text="Submit", actions=#alert { text="Hello" } } ].
30 Wiring an Action
30.1 Nitrogen Actions
30.1.1 Wiring an Action
Setting the actions
property of an element can lead to messy
code. Another, cleaner way to wire an action is the wf:wire/N
function.
body() -> wf:wire(mybutton, #effect { effect=pulsate }), [ #button { id=mybutton, text="Submit" } ].
31 Conditional Actions with #event{}
31.1 Nitrogen Actions
31.1.1 Conditional Actions with #event{}
Put the #effect{}
action inside of an #event{}
action. This
causes the effect to only get fired if the user clicks on
mybutton
.
body() -> wf:wire(mybutton, #event { type=click, actions=#effect { effect=pulsate } }), [ #button { id=mybutton, text="Submit" } ].
32 Triggers and Targets
32.1 Nitrogen Actions
32.1.1 Triggers and Targets
All actions have a target
property. The target
specifies what
element(s) the action effects.
The event action also has a trigger
property. The trigger
specifies what element(s) trigger the action.
Try this:
body() -> wf:wire(#event { type=click, trigger=mybutton, target=mylabel, actions=#effect { effect=pulsate } }), [ #label { id=mylabel, text="Make Me Blink!" }, #button { id=mybutton, text="Submit" } ].
33 Triggers and Targets
33.1 Nitrogen Actions
33.1.1 Triggers and Targets
You can also specify the Trigger and Target directly in wf:wire/N
. It takes three forms:
% Specify a trigger and target. wf:wire(Trigger, Target, Actions) % Use the same element for both trigger and target. wf:wire(TriggerAndTarget, Actions) % Assume the trigger and/or target is provided in the actions. % If not, then wire the action directly to the page. % (Useful for catching keystrokes.) wf:wire(Actions)
34 Quick Review
34.1 Nitrogen Actions
34.1.1 Quick Review
- Elements make HTML.
- Actions make Javascript.
-
An action can be wired using the
actions
property, or wired later withwf:wire/N
. Both approaches can take a single action or a list of actions. -
An action looks for
trigger
andtarget
properties. These can be specified in a few different ways. - Everything we have seen so far happens on the client.
35 PART 5 AGENDA
35.1 Nitrogen Events
- What is a Postback?
- Your First Postback
- Event Properties
- More Event Examples
- Postback Shortcuts
- Modifying Elements
36 What is a Postback?
36.1 Nitrogen Events
36.1.1 What is a Postback?
A postback briefly transfers control from the browser to the
Nitrogen server. It is initiated when an event fires with the
postback
property set. For example:
#event { type=click, postback=my_click_event }
The postback tag can be any valid Erlang term. You use this to differentiate incoming events.
37 Your First Postback
37.1 Nitrogen Events
37.1.1 Your First Postback
First, let's use the postback to print out a debug message.
body() -> wf:wire(mybutton, #event { type=click, postback=myevent }), [ #button { id=mybutton, text="Submit" } ]. event(myevent) -> ?PRINT({event, now()}).
38 Postback Shortcuts
38.1 Nitrogen Events
38.1.1 Postback Shortcuts
A few elements allow you to set the postback
property as a
shortcut to handle their most common events.
| Element | Shortcut Event |
#button{} | click |
#textbox{} | enter key |
#checkbox{} | click |
#dropdown{} | change |
#password{} | enter key |
39 Postback Shortcuts
39.1 Nitrogen Events
39.1.1 Postback Shortcuts
A few elements allow you to set the postback
property as a
shortcut to handle their most common events.
The previous code, simplified:
body() -> [ #button { id=mybutton, text="Submit", postback=myevent } ]. event(myevent) -> ?PRINT({event, now()}).
40 More Event Examples
40.1 Nitrogen Events
40.1.1 More Event Examples
body() -> % 'mouseover', 'click', and 'mouseout' are standard Javascript % events. wf:wire(mybutton, [ #event { type=mouseover, postback=my_mouseover_event } #event { type=click, postback=my_click_event } #event { type=mouseout, postback=my_mouseout_event } ]), [ #button { id=mybutton, text="Submit" } ]. event(my_click_event) -> ?PRINT({click, now()}); event(OtherEvent) -> ?PRINT({other, MyEvent, now()}).
41 More Event Examples
41.1 Nitrogen Events
41.1.1 More Event Examples
Generally, a postback is a good chance to read form elements. The
wf:q(ElementID)
function does this.
body() -> [ #textbox { id=mytextbox, text="Edit this text." }, #button { id=mybutton, text="Submit", postback=myevent } ]. event(myevent) -> Text = wf:q(mytextbox), ?PRINT({event, Text}).
42 Modifying Elements
42.1 Nitrogen Events
42.1.1 Modifying Elements
Here is where everything comes together: we are going to modify the page from within a postback event. Nitrogen uses AJAX to update parts of a page without updating the entire page.
body() -> #panel { style="margin: 50px;", body=[ #button { id=mybutton, text="Submit", postback=click }, #panel { id=placeholder } ]}. event(click) -> wf:update(placeholder, [ #h1 { text="Congratulations!" }, #p { body="You have updated the page!" }, #p { body=io_lib:format("~p", [now()]) } ]).
43 More Page Manipulation
43.1 Nitrogen Events
43.1.1 More Page Manipulation
The wf
module exposes many manipulation functions:
wf:update/2
- Update the contents of an element with another element(s).
wf:insert_top/2
- Insert a new element(s) at the beginning of another element.
wf:insert_bottom/2

44.1 Remembering State
- Page State vs. Session State
- Page State Example
- Session State Example
45 Page State vs. Session State
45.1 Remembering State
45.1.1 Page State vs. Session State
Nitrogen can store two kinds of state:
-
Page State
- Stored in a user's browser window.
- Destroyed when the user closes the window or navigates to a different page.
- Sent across the wire with each request.
-
Session State
- Stored in server memory.
- Destroyed when the session expires or the Erlang VM dies.
- Associated with the user's session by an HTTP cookie.
- Useful place to store authentication
46 Page State
46.1 Remembering State
46.1.1 Page State
Using Page State:
% Set a state variable wf:state(Key, Value) % Get a state variable wf:state(Key) wf:state_default(Key, DefaultValue)
Key
and Value
can be any valid Erlang term.
Exercise: Modify my_page.erl to display a counter that gets incremented every time you press the 'Submit' button. The counter should reset when the user reloads the page.
47 Page State
47.1 Remembering State
47.1.1 Page State
body() -> #panel { style="margin: 50px;", body=[ #button { id=mybutton, text="Submit", postback=click }, #panel { id=placeholder, body="1" } ]}. event(click) -> Counter = wf:state_default(counter, 1), wf:update(placeholder, [ #panel { body=io_lib:format("~p", [Counter + 1]) } ]), wf:state(counter, Counter + 1).
48 Session State
48.1 Remembering State
48.1.1 Session State
Using Session State:
% Set a session state variable wf:session(Key, Value) % Get a session state variable wf:session(Key) wf:session_default(Key, DefaultValue)
Key
and Value
can be any valid Erlang term.
Exercise: Modify my_page.erl to display TWO counters. When the user presses the 'Submit' button, one counter should get incremented, the other counter should get doubled. The server should remember the counter even if the closes and then re-opens the browser.
49 Session State
49.1 Remembering State
49.1.1 Session State
body() -> #panel { style="margin: 50px;", body=[ #button { id=mybutton, text="Submit", postback=click }, #panel { id=placeholder1, body="1" }, #panel { id=placeholder2, body="1" } ]}. event(click) -> %% Increment the counter... Counter1 = wf:session_default(counter1, 1), wf:update(placeholder1, io_lib:format("~p", [Counter1 + 1])), wf:session(counter1, Counter1 + 1), %% Double the other counter... Counter2 = wf:session_default(counter2, 1), wf:update(placeholder2, io_lib:format("~p", [Counter2 * 2])), wf:session(counter2, Counter2 * 2).

50.1 Security
- Limiting Access to a Page
- Authentication and Authorization Functions
- Page Redirection Functions
- Creating a Secure Page
51 Limiting Access to a Page
51.1 Security
51.1.1 Limiting Access to a Page
Nitrogen contains functions to help you build password protected websites:
-
Nitrogen is built for role-based security. You set the roles for
a current session, and check those roles later.
For example, the user may have the
friend
andmanager
roles, but not theadministrator
role. - Authentication/authorization info is stored in the session.
52 Authentication and Authorization Functions
52.1 Security
52.1.1 Authentication and Authorization Functions
Functions to set the user/role:
% Get/set the current user for this session. wf:user(), wf:user(User) % Get/set whether the current session has the specified role. wf:role(Role), wf:role(Role, IsInRole)
53 Page Redirection Functions
53.1 Security
53.1.1 Page Redirection Functions
Functions kick the user to a login page:
% Redirect the user to a different page. wf:redirect(Url) % Redirect the user to the login page. wf:redirect_to_login(LoginUrl) % Redirect the user back to the original page they % tried to access. wf:redirect_from_login(DefaultUrl)
54 Creating a Secure Page - Step 1
54.1 Security
54.1.1 Creating a Secure Page - Step 1
Check for the managers
role at the top of a page. If the user
doesn't have the role, go to a login page.
main() -> case wf:role(managers) of true -> #template { file="./site/templates/bare.html" }; false -> wf:redirect_to_login("/login") end.
55 Creating a Secure Page - Step 2
55.1 Security
55.1.1 Creating a Secure Page - Step 2
Create a login page. For now, just create a button that, when
clicked, grants the managers
role to the user and redirects
back.
body() -> #button { text="Login", postback=login }. event(login) -> wf:role(managers, true), wf:redirect_from_login("/").

58.1 Validation
- Overview of Nitrogen Validation
- Adding Some Validators
59 Overview of Nitrogen Validation
59.1 Validation
59.1.1 Overview of Nitrogen Validation
Nitrogen implements a validation framework, plus a number of pre-built validators, to allow you to declaratively validate your form variables.
Validation happens on both client side (using the LiveValidation library) and server side (in Erlang).
This is done to present a responsive front end to the user
60 Overview of Nitrogen Validation
60.1 Validation
60.1.1 Overview of Nitrogen Validation
The simplest validator is the #is_required{}
validator. Tell your
login.erl
page to make sure the user enters both a username and
a password.
body() -> wf:wire(submit, username, #validate { validators=[ #is_required { text="Required." } ]}), wf:wire(submit, password, #validate { validators=[ #is_required { text="Required." } ]}), #panel { style="margin: 50px;", body=[ ...
61 Overview of Nitrogen Validation
61.1 Validation
61.1.1 Overview of Nitrogen Validation
We can get clever and use a validator to check that the user
entered the correct password. The #custom{}
validator runs on
the server. (To make a custom client-side validator, use
#js_custom{}
.)
body() -> wf:wire(submit, username, #validate { validators=[ #is_required { text="Required." } ]}), wf:wire(submit, password, #validate { validators=[ #is_required { text="Required." }, #custom { text="Invalid password.", function=fun(_, Value) -> Value == "password" end } ]}), #panel { style="margin: 50px;", body=[ ...
62 Overview of Nitrogen Validation
62.1 Validation
62.1.1 Overview of Nitrogen Validation
Since we validate the password in the #custom
validator, we can
trust that the login
event only fires when the password is
correct. Change the login
event to:
event(login) -> wf:role(managers, true), wf:redirect_from_login("/").

63.1 Comet
- What is Comet?
- Comet the Nitrogen/Erlang Way
- A Comet Counter
- Comet Pools
- Comet Pool Scope
- The Simplest Chatroom Ever Constructed
64 What is Comet?
64.1 Comet
64.1.1 What is Comet?
Comet is the name for a technique where the browser requests something from the server, and the server doesn't respond until it has something useful to say.
This makes it useful for applications that need fast, out-of-band communication, such as chat rooms.
In other words, you don't need to keep hitting a "Get Messages" button. The server just pushes messages when they are available.
A big happy shout out to Tom McNulty for his innovative ideas on what Comet support could look like in Nitrogen.
65 Comet the Nitrogen/Erlang Way
65.1 Comet
65.1.1 Comet the Nitrogen/Erlang Way
Think of Comet like erlang:spawn/1
:
- Start up a function.
-
The function can manipulate the page using
wf:update/2
or any other page manipulation function. -
Output is queued until the function ends or calls
wf:flush/0
. -
The function acts like it is linked to the current user's
page. It is killed when the user leaves the page (or receives
{'EXIT', _, Message}
iftrap_exit
istrue
.)
66 A Comet Counter
66.1 Comet
66.1.1 A Comet Counter
Update my_page.erl
to count once per second.
body() -> wf:comet(fun() -> counter(1) end), #panel { id=placeholder }. counter(Count) -> timer:sleep(1000), wf:update(placeholder, integer_to_list(Count)), wf:flush(), counter(Count + 1).
67 Comet Pools
67.1 Comet
67.1.1 Comet Pools
You can tell a Comet function to start in a pool by providing a
PoolName
. The PoolName
can be any Erlang term.
wf:comet(Fun, PoolName)
Now you can send messages to the pool. The messages will be received by other functions started in that comet pool.
wf:send(PoolName, Message)
68 Comet Pool Scope
68.1 Comet
68.1.1 Comet Pool Scope
So far, we've been creating local comet pools. Nitrogen also has the idea of global comet pools:
- Local comet pools are walled around the current page and the current user. If the user reloads the page, the comet process(es) goes away.
- Global comet pools exist to help you create multi-user applications. They pool is accessible by all pages and all users.
%% Create a global comet pool. wf:comet_global(Function, PoolName) %% Send a global comet message. wf:send_global(PoolName, Message)
69 The Simplest Chatroom Ever Constructed
69.1 Comet
69.1.1 The Simplest Chatroom Ever Constructed
Here we're going to create a page that listens for some text, and sends it to the global comet pool. Connect with different browsers and chat to yourself.
body() -> wf:comet_global(fun() -> repeater() end, repeater_pool), [ #textbox { id=msg, text="Your message...", next=submit }, #button { id=submit, text="Submit", postback=submit }, #panel { id=placeholder } ]. event(submit) -> ?PRINT(wf:q(msg)), wf:send_global(repeater_pool, {msg, wf:q(msg)}). repeater() -> receive {msg, Msg} -> wf:insert_top(placeholder, [Msg, "<br>"]) end, wf:flush(), repeater().

71 Custom Elements - Part 1
71.1 Extending Nitrogen
71.1.1 Custom Elements - Part 1
You can create custom elements to encapsulate other elements. There is no difference between a custom element and a built-in element, except where the actual files are stored.
Create a new custom element in site/src/elements/my_element.erl
.
./bin/dev element my_element
72 Custom Elements - Part 2
72.1 Extending Nitrogen
72.1.1 Custom Elements - Part 2
An element has:
- A record containing the properties of the element.
-
A
reflect()
function, providing a programattic way to get the properties of an element. Ifrecord_info(fields, RecordType)
worked, this would not be necessary.) -
A
render_element(Record)
function that emits HTML or other elements.
73 Custom Elements - Part 3
73.1 Extending Nitrogen
73.1.1 Custom Elements - Part 3
Let's make an element that displays a textbox and a button, logs the result of the textbox to the console, and then calls a method on the main page.
render_element(#my_element{}) -> TextboxID = wf:temp_id(), ButtonID = wf:temp_id(), wf:wire(ButtonID, #event { type=click, delegate=?MODULE, postback={click, TextboxID} }), [ #textbox { id=TextboxID, text="Your text...", next=ButtonID }, #button { id=ButtonID, text="Submit" } ]. event({click, TextboxID}) -> Text = wf:q(TextboxID), ?PRINT({clicked, TextboxID, Text}), PageModule = wf:page_module(), PageModule:my_element_event(Text).

Let's make a custom action that calls #alert{}
with a specified
string, but converted to all uppercase.
-record(my_action, {?ACTION_BASE(action_my_action), text}). render_action(Record = #my_action{}) -> #alert { text=string:to_upper(Record#my_action.text) }.
77 Custom Actions - Part 3
77.1 Extending Nitrogen
77.1.1 Custom Actions - Part 3
Now, use the element on my_page.erl
. Remember to move the action

differently depending on the role of a user.
80 Handlers - Part 3
80.1 Extending Nitrogen
80.1.1 Handlers - Part 3
Let's make a security_handler
handler that only allows the user

Note
This document gives a brief overview of TinyOS 2.0, highlighting how and where it departs from 1.1 and 1.0. Further detail on these changes is detailed in TEP (TinyOS Enhancement Proposal) documents.
TinyOS 2.0 is a clean slate redesign and re-implementation of TinyOS. Its development was motivated by our belief that many aspects of 1.x strain to meet requirements and uses that were not foreseen when it was designed and implemented. The structure and interfaces 1.x defines have several fundamental limitations. While these limitations can be worked around, this practice has led to tightly coupled components, hard to find interactions, and a very steep learning curve for a newcomer to sensor network programming.
TinyOS 2.0 is not backwards compatible with 1.x: code written for the latter will not compile for the former. However, one important aspect of 2.0's design is to minimize the difficulty of upgrading code. Therefore, while porting a 1.x application to 2.0 will require some work, it should not be very much.
This document provides a high-level overview of 2.0 and describes some of the ways in which it departs from 1.x. It covers the basic TinyOS abstractions, such as hardware abstractions, communication, timers, the scheduler, booting and initialization. Further detail on each of these can be found in TEPs (TinyOS Enhancement Proposals), which document and describe these abstractions.
Platforms exist in the tos/platforms subdirectory. In TinyOS 2.0, a platform is a collection of chips and some glue code that connects them together. For example, the mica2 platform is the CC1000 radio chip and the ATmega128 microcontroller, while the micaZ platform is the CC2420 radio and the ATmega128 microcontroller, and the Teloi platforms are the CC2420 radio and the MSP430 microcontroller. Chip code exists in tos/chips. A platform directory generally has a .platform file, which has options to pass to the nesC compiler. For example, the mica2 .platform file tells ncc to look in chips/cc1000 and chips/atm128 directories, as well as to use avr-gcc to compile a mote binary (Teloi platforms tell it to use msp430-gcc).
Hardware abstractions in TinyOS 2.0 generally follow a three-level abstaction heirarchy, called the HAA (Hardware Abstraction Architecture).
At the bottom of the HAA is the HPL (Hardware Presentation Layer). The HPL is a thin software layer on top of the raw hardware, presenting hardare such as IO pins or registers as nesC interfaces. The HPL generally has no state besides the hardware itself (it has no variables). HPL components usually have the prefix Hpl, followed by the name of the chip. For example, the HPL components of the CC1000 begin with HplCC1000.
The middle of the HAA is the HAL (Hardware Abstraction Layer). The HAL builds on top of the HPL and provides higher-level abstractions that are easier to use than the HPL but still provide the full functionality of the underlying hardware. The HAL components usually have a prefix of the chip name. For example, the HAL components of the CC1000 begin with CC1000.
The top of the HAA is the HIL (Hardware Independent Layer). The HIL builds on top of the HAL and provides abstractions that are hardware independent. This generalization means that the HIL usually does not provide all of the functionality that the HAL can. HIL components have no naming prefix, as they represent abstractions that applications can use and safely compile on multiple platforms. For example, the HIL component of the CC1000 on the mica2 is ActiveMessageC, representing a full active message communication layer.
The HAA is described in TEP 2: Hardware Abstraction Architecture[TEP2].
Currently (as of the 2.0 release in November 2006), TinyOS 2.0 supports the following platforms:
- eyesIFXv2
- intelmote2
- mica2
- mica2dot
- micaZ
- telosb
- tinynode
- btnode3
The btnode3 platform is not included in the RPM.
As with TinyOS 1.x, TinyOS 2.0 scheduler has a non-preemptive FIFO policy. However, tasks in 2.0 operate slightly differently than in 1.x.
In TinyOS 1.x, there is a shared task queue for all tasks, and a component can post a task multiple times. If the task queue is full, the post operation fails. Experience with networking stacks showed this to be problematic, as the task might signal completion of a split-phase operation: if the post fails, the component above might block forever, waiting for the completion event.
In TinyOS 2.x, every task has its own reserved slot in the task queue, and a task can only be posted once. A post fails if and only if the task has already been posted. If a component needs to post a task multiple times, it can set an internal state variable so that when the task executes, it reposts itself.
This slight change in semantics greatly simplifies a lot of component code. Rather than test to see if a task is posted already before posting it, a component can just post the task. Components do not have to try to recover from failed posts and retry. The cost is one byte of state per task. Even in large systems such as TinyDB, this cost is under one hundred bytes (in TinyDB is is approximately 50).
Applications can also replace the scheduler, if they wish. This allows programmers to try new scheduling policies, such as priority- or deadline-based. It is important to maintain non-preemptiveness, however, or the scheduler will break all nesC's static concurrency analysis. Details on the new scheduler and how to extend it can be found in TEP 106: Schedulers and Tasks[TEP106].
TinyOS 2.0 has a different boot sequence than 1.x. The 1.x interface StdControl has been split into two interfaces: Init and StdControl. The latter only has two commands: start and stop. In TinyOS 1.x, wiring components to the boot sequence would cause them to be powered up and started at boot. That is no longer the case: the boot sequence only initializes components. When it has completed initializing the scheduler, hardware, and software, the boot sequence signals the Boot.booted event. The top-level application component handles this event and start services accordingly. Details on the new boot sequence can be found in TEP 107: TinyOS 2.x Boot Sequence[TEP107].
TinyOS 2.0 is written with nesC 1.2, which introduces the concept of a 'generic' or instantiable component. Generic modules allow TinyOS to have reusable data structures, such as bit vectors and queues, which simplify development. More importantly, generic configurations allow services to encapsulate complex wiring relationships for clients that need them.
In practice, this means that many basic TinyOS services are now virtualized. Rather than wire to a component with a parameterized interface (e.g., GenericComm or TimerC in 1.x), a program instantiates a service component that provides the needed interface. This service component does all of the wiring underneath (e.g., in the case of timers, to a unique) automatically, reducing wiring mistakes and simplifying use of the abstraction.
TinyOS 2.0 provides a much richer set of timer interfaces than 1.x. Experience has shown that timers are one of the most critical abstractions a mote OS can provide, and so 2.0 expands the fidelity and form that timers take. Depending on the hardware resources of a platform, a component can use 32KHz as well as millisecond granularity timers, and the timer system may provide one or two high-precision timers that fire asynchronously (they have the async keyword). Components can query their timers for how much time remainins before they fire, and can start timers in the future (e.g., 'start firing a timer at 1Hz starting 31ms from now'). TEP 102: Timers[TEP102] defines what HIL components a platform must provide in order to support standard TinyOS timers. Platforms are required to provide millisecond granularity timers, and can provide finer granularity timers (e.g., 32kHz) if needed.
Timers present a good example of virtualization in 2.0. In 1.x, a program instantiates a timer by wiring to TimerC:
components App, TimerC; App.Timer -> TimerC.Timer[unique("Timer")];
In 2.0, a program instantiates a timer:
components App, new TimerMilliC(); App.Timer -> TimerMilliC;
In TinyOS 2.0, the message buffer type is message_t, and it is a buffer that is large enough to hold a packet from any of a node's communication interfaces. The structure itself is completely opaque: components cannot reference its fields. Instead, all buffer accesses go through interfaces. For example, to get the destination address of an AM packet named msg, a component calls AMPacket.destination(msg).
Send interfaces distinguish the addressing mode of communication abstractions. For example, active message communication has the AMSend interface, as sending a packet require an AM destination address. In contrast, broadcasting and collection tree abstractions have the address-free Send interface.
Active messages are the network HIL. A platform's ActiveMessageC component defines which network interface is the standard communication medium. For example, a mica2 defines the CC1000 active message layer as ActiveMessageC, while the TMote defines the CC2420 active message layer as ActiveMessageC.
There is no longer a TOS_UART_ADDRESS for active message communication. Instead, a component should wire to SerialActiveMessageC, which provides active message communication over the serial port.
Active message communication is virtualized through four generic components, which take the AM type as a parameter: AMSenderC, AMReceiverC, AMSnooperC, and AMSnoopingReceiverC. AMSenderC is virtualized in that the call to send() does not fail if some other component is sending (as it does with GenericComm in 1.x). Instead, it fails only if that particular AMSenderC already has a packet outstanding or if the radio is not in a sending state. Underneath, the active message system queues and sends these outstanding packets. This is different than the QueuedSendC approach of 1.x, in which there is an N-deep queue that is shared among all senders. With N AMSenderC components, there is an N-deep queue where each sender has a single reserved entry. This means that each AMSenderC receives 1/n of the available post-MAC transmission opportunities, where n is the number of AMSenderC components with outstanding packets. In the worst case, n is the number of components; even when every protocol and component that sends packets is trying to send a packet, each one will receive its fair share of transmission opportunities.
Further information on message_t can be found in TEP 111: message_t[TEP111], while further information on AM can be found in TEP 116: Packet Protocols[TEP116].
The current TinyOS release has a low-power stack for the CC1000 radio (mica2 platform) and an experimental low-power stack for the CC2420 radio (micaz, telosb, and intelmote2 platforms).
In TinyOS 2.0, named sensor components comprise the HIL of a platform's sensors. TEP 114 describes a set of HIL data acquisition interfaces, such as Read, ReadStream, and Get, which sensors provide according to their acquisition capabilities.
If a component needs high-frequency or very accurate sampling, it must use the HAL, which gives it the full power of the underlying platform (highly accurate platform-independent sampling is not really feasible, due to the particulars of individual platforms). Read assumes that the request can tolerate some latencies (for example, it might schedule competing requests using a FIFO policy).
Details on the ADC subsystem can be found in TEP 101: Analog-to-Digital Converters[TEP101]; details on the organization of sensor boards can be found in TEP 109: Sensorboards[TEP109], and the details of the HIL sensor interfaces can be found in TEP 114: Source and Sink Independent Drivers[TEP114].
The standard TinyOS 1.x return code is result_t, whose value is either SUCCESS (a non-zero value) or FAIL (a zero value). While this makes conditionals on calls very easy to write (e.g., if (call A.b())), it does not allow the callee to distinguish causes of error to the caller. In TinyOS 2.0, result_t is replaced by error_t, whose values include SUCCESS, FAIL, EBUSY, and ECANCEL. Interface commands and events define which error codes they may return and why.
From the perspective of porting code, this is the most significant different in 2.0. Calls that were once:
if (call X.y()) { busy = TRUE; }
now have their meanings reversed. In 1.x, the busy statement will execute if the call succeeds, while in 2.0 it will execute if the call fails. This encourages a more portable, upgradable, and readable approach:
if (call X.y() == SUCCESS) { busy = TRUE; }
While basic abstractions, such as packet communication and timers, can be virtualized, experiences with 1.x showed that some cannot without either adding significant complexity or limiting the system. The most pressing example of this is a shared bus on a microcontroller. Many different systems -- sensors, storage, the radio -- might need to use the bus at the same time, so some way of arbitrating access is needed.
To support these kinds of abstractions, TinyOS 2.0 introduces the Resource interface, which components use to request and acquire shared resources, and arbiters, which provide a policy for arbitrating access between multiple clients. For some abstractions, the arbiter also provides a power management policy, as it can tell when the system is no longer needed and can be safely turned off.
TEP 108: Resource Arbitration[TEP108] describes the Resource interface and how arbiters work.
Power management in 2.0 is divided into two parts: the power state of the microcontroller and the power state of devices. The former, discussed in TEP 112: Microcontroller Power Management[TEP112], is computed in a chip-specific manner by examining which devices and interrupt souces are active. The latter, discussed in TEP 115: Power Management of Non-Virtualised Devices{TEP115], is handled through resource abiters. Fully virtualized services have their own, individual power management policies.
TinyOS 2.0 provides low-power stacks for the CC1000 (mica2) and CC2420 (micaz, telosb, imote2) radios. Both use a low-power listening apporach, where transmitters send long preambles or repeatedly send packets and receivers wake up periodically to sense the channel to hear if there is a packet being transmitted. The low-power stack CC1000 is standard, while the CC2420 stack is experimental. That is, the default CC1000 stack (chips/cc1000) has low-power-listening, while the default CC2420 stack (chips/cc2420) does not. To use the low-power CC2420 stack, you must include chips/cc2420_lpl in your application Makefile.
TinyOS 2.0 provides simple reference implementations of two of the most basic protocols used in mote networks: dissemination and collection. Dissemination reliably delivers small (fewer than 20 byte) data items to every node in a network, while collection builds a routing tree rooted at a sink node. Together, these two protocols enable a wide range of data collection applications. Collection has advanced significantly since the most recent beta release; experimental tests in multiple network conditions have seen very high (>98%) deliver rates as long as the network is not saturated.
TinyOS 2.0 represents the next step of TinyOS development. Building on user experiences over the past few years, it has taken the basic TinyOS architecture and pushed it forward in several directions, hopefully leading to simpler and easier application development. It is still under active development: future prereleases will include non-volatile storage, basic multihop protocols (collection routing, dissemination), and further power management abstractions.
TinyOS 2.0 is the result of a lot of hard work from a lot of people, including (but not limited to) David Gay, Philip Levis, Cory Sharp, Vlado Handziski, Jan Hauer, Kevin Klues, Joe Polastre, Jonathan Hui, Prabal Dutta, Gilman Tolle, Martin Turon, Phil Buonodonna, Ben Greenstein, David Culler, Kristin Wright, Ion Yannopoulos, Henri Dubois-Ferriere, Jan Beutel, Robert Szewczyk, Rodrigo Fonseca, Kyle Jamieson, Omprakash Gnawali, David Moss, and Kristin Wright.

I can hear you thinking: "What? Dresscode? What would that be? Did I click on the wrong link? "
Nope, this is the page where I tell you all about the awesome stuff I do with Dresscode: the organization for female IT-students at my university!
"Sounds cool Noelle, but what do you guys (oops, I mean girls) do?" Well, this what I have done in the past year:
organize events for young girls, to show them how much fun coding is
give workshops at events (like CodeEvent, organized in collaboration with VHTO)
speak at events (like the kick-off of a project about the computational thinking of teachers, organized by Google and VHTO!)
help at open days of the university and study, to show future students that there are actual female computer engineers. The percentage of women in the IT-studies at our university actually increased, so that may show that it actually works :)
organize team building activities. As a team building activity I decided that it would be fun to go to an escape room with some of the Dresscoders. It was a lot of organizing but so much fun in the end!
have a drink every once in a while and talk about life
Great right? Since pictures speak louder than words, here are some:
Kick-Off DigiLeerkrachten
Tell in a panel about my experiences as a female programmer
Workshop Arduino
At CodeEvent I taught girls ages 9-13 about all the cool things you can do with an Arduino
Co-Dresscoder Imani!
I actually co-taught the Arduino workshop with this amazing lady: Imani!
Team Building: Escape Room
Post-escape room photos. Look at how relieved we are that we were out of those rooms haha!
Helping at Open Days
It's just a lot of fun telling future students about your cool study, okay.


Veterinarians are required to notify localities when a dog is vaccinated for rabies. If the dog doesn’t have a current Montgomery County dog license, then you need to purchase one. If not purchased within 90 days of vaccination date, the Treasurer will send the owner an Application for Dog License. If after 30 days of notice, the owner still has not purchased a dog license, the Treasurer shall notify animal control that an owner is in possession of a vaccinated animal without a current dog license.
IMPORTANT: State Law requires that all dogs FOUR (4) MONTHS OLD OR OLDER must have a certificate of rabies vaccination signed by the veterinarian with the veterinarian’s license number and expiration date of the vaccination. Please complete and return this form to purchase the required DOG licenses.
**FOR EACH LICENSE PURCHASED, A CURRENT ORIGINAL CERTIFICATE OF RABIES VACCINATION MUST BE PRESENTED.** Dog license must be fastened to a collar and worn by the dog. If a tag is lost or destroyed, apply for a duplicate tag immediately by presenting the original receipt to the Treasurer’s Office.
Dog tags go on sale November 1st at the Treasurer's Office or the Blacksburg Municipal Building. Dog tags are due by January 31st of each year.

“Where are we, father?” Sylvie whispered, with her arms twined closely around the old man’s neck, and with her rosy cheek lovingly pressed to his.
“In Elfland, darling. It’s one of the provinces of Fairyland.”
“But I thought Elfland was ever so far from Outland: and we’ve come such a tiny little way!”
“You came by the Royal Road, sweet one. Only those of royal blood can travel along it: but you’ve been royal ever since I was made King of Elfland that’s nearly a month ago. They sent two ambassadors, to make sure that their invitation to me, to be their new King, should reach me. One was a Prince; so he was able to come by the Royal Road, and to come invisibly to all but me: the other was a Baron; so he had to come by the common road, and I dare say he hasn’t even arrived yet.”
“Then how far have we come?” Sylvie enquired.
“Just a thousand miles, sweet one, since the Gardener unlocked that door for you.”
“A thousand miles!” Bruno repeated.  “I mean may I eat one of that fruits?”
“Yes, child,” said his father: “and then you’ll find out what Pleasure is like—the Pleasure we all seek so madly, and enjoy so mournfully!”
Bruno ran eagerly to the wall, and picked a fruit that was shaped something like a banana, but had the color of a strawberry.
He ate it with beaming looks, that became gradually more gloomy, and were very blank indeed by the time he had finished.
“It hasn’t got no taste at all!” he complained. “I couldn’t feel nuffin in my mouf! It’s a—what’s that hard word, Sylvie?”
“It was a Phlizz,” Sylvie gravely replied. “Are they all like that, father?”
“They’re all like that to you, darling, because you don’t belong to Elfland—yet. But to me they are real.”
Bruno looked puzzled. “I’ll try anuvver kind of fruits!” he said, and jumped down off the King’s knee. “There’s some lovely striped ones, just like a rainbow!” And off he ran.
Meanwhile the Fairy-King and Sylvie were talking together, but in such low tones that I could not catch the words: so I followed Bruno, who was picking and eating other kinds of fruit, in the vain hope of finding some that had a taste. I tried to pick so me myself—but it was like grasping air, and I soon gave up the attempt and returned to Sylvie.
“Look well at it, my darling,” the old man was saying, “and tell me how you like it.”
“’It’s just lovely,” cried Sylvie, delightedly. “Bruno, come and look!” And she held up, so that he might see the light through it, a heart-shaped Locket, apparently cut out of a single jewel, of a rich blue color, with a slender gold chain attached to it.
“It are welly pretty,” Bruno more soberly remarked: and he began spelling out some words inscribed on it. “All—will—love—Sylvie,” he made them out at last. “And so they doos!” he cried, clasping his arms round her neck. “Everybody loves Sylvie!”
“But we love her best, don’t we, Bruno?” said the old King, as he took possession of the Locket. “Now, Sylvie, look at this.” And he showed her, lying on the palm of his hand, a Locket of a deep crimson color, the same shape as the blue one and, like it, attached to a slender golden chain.
“Lovelier and lovelier!” exclaimed Sylvie, clasping her hands in ecstasy. “Look, Bruno!”
“And there’s words on this one, too,” said Bruno. “Sylvie—will—love—all.”
“Now you see the difference,” said the old man: “different colors and different words.
Choose one of them, darling. I’ll give you which ever you like best.”
Sylvie whispered the words, several times over, with a thoughtful smile, and then made her decision. “It’s very nice to be loved,” she said: “but it’s nicer to love other people! May I have the red one, Father?”
The old man said nothing: but I could see his eyes fill with tears, as he bent his head and pressed his lips to her forehead in a long loving kiss. Then he undid the chain, and showed her how to fasten it round her neck, and to hide it away under the edge of her frock. “It’s for you to keep you know he said in a low voice, not for other people to see. You’ll remember how to use it?
Yes, I’ll remember, said Sylvie.
“And now darlings it’s time for you to go back or they’ll be missing you and then that poor Gardener will get into trouble!”
Once more a feeling of wonder rose in my mind as to how in the world we were to get back again—since I took it for granted that wherever the children went I was to go—but no shadow of doubt seemed to cross their minds as they hugged and kissed him murmuring over and over again “Good-bye darling Father!” And then suddenly and swiftly the darkness of midnight seemed to close in upon us and through the darkness harshly rang a strange wild song:—
He thought he saw a Buffalo
Upon the chimney-piece:
He looked again, and found it was
His Sister’s Husband’s Niece.
‘Unless you leave this house,’ he said,
‘I’ll send for the Police!’
“That was me!” he added, looking out at us, through the half-opened door, as we stood waiting in the road.’ “And that’s what I’d have done—as sure as potatoes aren’t radishes—if she hadn’t have tooken herself off! But I always loves my pay-rints like anything.”
“Who are oor pay-rints?” said Bruno.
“Them as pay rint for me, a course!” the Gardener replied. “You can come in now, if you like.”
He flung the door open as he spoke, and we got out, a little dazzled and stupefied (at least I felt so) at the sudden transition from the half-darkness of the railway-carriage to the brilliantly-lighted platform of Elveston Station.
A footman, in a handsome livery, came forwards and respectfully touched his hat. “The carriage is here, my Lady,” he said, taking from her the wraps and small articles she was carrying: and Lady Muriel, after shaking hands and bidding me “Good-night!” with a pleasant smile, followed him.
It was with a somewhat blank and lonely feeling that I betook myself to the van from which the luggage was being taken out: and, after giving directions to have my boxes sent after me, I made my way on foot to Arthur’s lodgings, and soon lost my lonely feeling in the hearty welcome my old friend gave me, and the cozy warmth and cheerful light of the little sitting-room into which he led me.
“Little, as you see, but quite enough for us two. Now, take the easy-chair, old fellow, and let’s have another look at you! Well, you do look a bit pulled down!” and he put on a solemn professional air. “I prescribe Ozone, quant. suff. Social dissipation, fiant pilulae quam plurimae: to be taken, feasting, three times a day!”
“But, Doctor!” I remonstrated. “Society doesn’t ‘receive’ three times a day!”
“That’s all you know about it!” the young Doctor gaily replied. “At home, lawn-tennis, 3 P.M. At home, kettledrum, 5 P.M. At home, music (Elveston doesn’t give dinners), 8 P.M. Carriages at 10. There you are!”
It sounded very pleasant, I was obliged to admit. “And I know some of the lady-society already,” I added. “One of them came in the same carriage with me”
“What was she like? Then perhaps I can identify her.”
“The name was Lady Muriel Orme. As to what she was like—well, I thought her very beautiful. Do you know her?”
“Yes—I do know her.” And the grave Doctor colored slightly as he added “Yes, I agree with you. She is beautiful.”
“I quite lost my heart to her!” I went on mischievously. “We talked—”
“Have some supper!” Arthur interrupted with an air of relief, as the maid entered with the tray. And he steadily resisted all my attempts to return to the subject of Lady Muriel until the evening had almost worn itself away. Then, as we sat gazing into the fire, and conversation was lapsing into silence, he made a hurried confession.
“I hadn’t meant to tell you anything about her,” he said (naming no names, as if there were only one ‘she’ in the world!) “till you had seen more of her, and formed your own judgment of her: but somehow you surprised it out of me. And I’ve not breathed a word of it to any one else. But I can trust you with a secret, old friend! Yes! It’s true of me, what I suppose you said in jest.
“In the merest jest, believe me!” I said earnestly. “Why, man, I’m three times her age! But if she’s your choice, then I’m sure she’s all that is good and—”
“—and sweet,” Arthur went on, “and pure, and self-denying, and true-hearted, and—” he broke off hastily, as if he could not trust himself to say more on a subject so sacred and so precious. Silence followed: and I leaned back drowsily in my easy-chair, filled with bright and beautiful imaginings of Arthur and his lady-love, and of all the peace and happiness in store for them.
I pictured them to myself walking together, lingeringly and lovingly, under arching trees, in a sweet garden of their own, and welcomed back by their faithful gardener, on their return from some brief excursion.
It seemed natural enough that the gardener should be filled with exuberant delight at the return of so gracious a master and mistress and how strangely childlike they looked! I could have taken them for Sylvie and Bruno less natural that he should show it by such wild dances, such crazy songs!
“He thought he saw a Rattlesnake
That questioned him in Greek:
He looked again, and found it was
The Middle of Next Week.
‘The one thing I regret,’ he said,
‘Is that it cannot speak!”
—least natural of all that the Vice-Warden and ‘my Lady’ should be standing close beside me, discussing an open letter, which had just been handed to him by the Professor, who stood, meekly waiting, a few yards off.
“If it were not for those two brats,” I heard him mutter, glancing savagely at Sylvie and Bruno, who were courteously listening to the Gardener’s song, “there would be no difficulty whatever.”
“Let’s hear that bit of the letter again,” said my Lady. And the Vice-Warden read aloud:-
“—and we therefore entreat you graciously to accept the Kingship, to which you have been unanimously elected by the Council of Elfland: and that you will allow your son Bruno of whose goodness, cleverness, and beauty, reports have reached us—to be regarded as Heir-Apparent.”
“But what’s the difficulty?” said my Lady.
“Why, don’t you see? The Ambassador, that brought this, is waiting in the house: and he’s sure to see Sylvie and Bruno: and then, when he sees Uggug, and remembers all that about ‘goodness, cleverness, and beauty,’ why, he’s sure to—”
“And where will you find a better boy than Uggug?” my Lady indignantly interrupted. “Or a wittier, or a lovelier?”
To all of which the Vice-Warden simply replied “Don’t you be a great blethering goose! Our only chance is to keep those two brats out of sight. If you can manage that, you may leave the rest to me. I’ll make him believe Uggug to be a model of cleverness and all that.”
“We must change his name to Bruno, of course?” said my Lady.
The Vice-Warden rubbed his chin. “Humph! No!” he said musingly. “Wouldn’t do.   “He isn’t, indeed!”
My Lady was appeased. “Let’s go in and receive the Ambassador,” she said, and beckoned to the Professor. “Which room is he waiting in?” she inquired.
“In the Library, Madam.”
“And what did you say his name was?” said the Vice-Warden.
The Professor referred to a card he held in his hand. “His Adiposity the Baron Doppelgeist.”
“Why does he come with such a funny name?” said my Lady.
“He couldn’t well change it on the journey,” the Professor meekly replied, “because of the luggage.”
“You go and receive him,” my Lady said to the Vice-Warden, “and I’ll attend to the children.”

The Geode QueryService provides methods to create the Query object. You can then use the Query object to perform query-related operations.
The QueryService instance you should use depends on whether you are querying the local cache of an application or if you want your application to query the server cache.
Querying a Local Cache
To query the application’s local cache or to query other members, use org.apache.geode.cache.Cache.getQueryService
.
Sample Code
// Identify your query string.
String queryString = "SELECT DISTINCT * FROM /exampleRegion";
// Get QueryService from Cache.
QueryService queryService = cache.getQueryService();
// Create the Query Object.
Query query = queryService.newQuery(queryString);
// Execute Query locally. Returns results set.
SelectResults results = (SelectResults)query.execute();
// Find the Size of the ResultSet.
int size = results.size();
// Iterate through your ResultSet.
Portfolio p = (Portfolio)results.iterator().next(); /* Region containing Portfolio object. */
Querying a Server Cache from a Client
To perform a client to server query, use org.apache.geode.cache.client.Pool.getQueryService
.
Sample Code
// Identify your query string.
String queryString = "SELECT DISTINCT * FROM /exampleRegion";
// Get QueryService from client pool.
QueryService queryService = pool.getQueryService();
// Create the Query Object.
Query query = queryService.newQuery(queryString);
// Execute Query locally. Returns results set.
SelectResults results = (SelectResults)query.execute();
// Find the Size of the ResultSet.
int size = results.size();
// Iterate through your ResultSet.
Portfolio p = (Portfolio)results.iterator().next(); /* Region containing Portfolio object. */
Refer to the following JavaDocs for specific APIs:
Note:
You can also perform queries using the gfsh query
command. See query.


Suspected 'sperm-throwing terror' arrested in Tasikmalaya
by News DeskThe Tasikmalaya Police in West Java have arrested a man suspected of throwing semen at several women in a case that has become known as the “sperm terror” on social media.
Police arrested the suspect, identified as 25-year-old Sidiq Nugraha, at his relative’s house in Cihideung district on Monday. He was found hiding on the second floor of the house.
“He was charged with violating Article 281 of the Criminal Code on sexual harassment in public,” Tasikmalaya Police chief Adj. Sr. Comr. Anom Karibianto said on Monday, as quoted by kompas.com.
The crime carries a maximum punishment of two years and eight months imprisonment.
The case gained public attention after the first victim – identified only by her initials LR – and her husband shared the story of her encounter.
LR, 43, said that the incident took place on Saturday evening when she was hailing an ojek (motorcycle taxi) on the side of the street.

She recalled that she was approached by an unknown man riding a motorbike who shouted inappropriate words at her. The man put his hand into his trousers and threw his semen at LR. He then fled the scene.
“I called my husband to pick me up from the location. Fortunately the assailant’s semen did not reach me,” she said on Saturday.
Her husband, 45-year-old RF, posted photos of the alleged perpetrator and his motorcycle on his social media account. The photos were taken by his wife during the incident. When the photos went viral, the couple found out that LR was not the only victim.
“More than 10 women told their stories to us,” RF said. He added that one of the victims said she had semen thrown on her while she was walking with her husband.

Apart from throwing semen, they also found out that Sidiq allegedly groped women’s breasts. LR’s niece was a victim.
“She told me that an unknown man riding the same motorcycle groped her breasts while she was riding a motorcycle,” LR said.
Police chief Anom added that the police were still investigating the suspect’s motives and would work with a psychiatrist to determine them. (kuk)

CWPIL No. 4 of 2018 23.04.2018 Present: Mr. Bimal Gupta, Sr. Advocate, as Amicus .
Curiae with Ms. Rubeena Bhatt, Advocate.
Mr. Ashok Sharma, Advocate General with Mr. Ranjan Sharma, Additional Advocate General and Mr. J.K. Verma, Dy. Advocate General the respondents-State.
Mr. Tara Singh Chauhan, Advocate, for respondent No. 9.
The instant petition was initiated on the basis of a news report, highlighting inaction on the part of various functionaries/instrumentalities of the State in complying with the environmental laws and not taking steps for granting sanction for prosecuting the erring officer(s)/ official(s).
In the State of Himachal Pradesh, there are 61 urban local bodies, including cantonment boards and as per the news report, contrary to the provisions of law, municipal solid waste is allowed to be dumped in open, more so along the river side.
Unscientific disposal of the municipal solid waste has only aggravated the problem of environmental degradation. On 4th of July, 2017, we had directed the Deputy Commissioners of all the Districts, falling within the State of Himachal Pradesh, to file their personal affidavits, stating the progress with regard to the process initiated for taking action against the erring officer(s)/official(s), ::: Downloaded on - 24/04/2018 22:59:11 :::HCHP including grant of prosecution sanction. Taking note of such .
affidavits, on 23rd of October, 2017, we passed the following order:-
"One of the grievances pointed out by the learned Amicus Curiae is inaction on the part of the respondent-State/authorities in considering grant of sanction for prosecuting the erring officials/officers, who were posted as Executive Officers, Municipal Council, Chamba and Parwanoo at the relevant time. From the affidavits filed by the Chief Secretary, Government of Himachal Pradesh and Principal Secretary (Environment Science & Technology), Government of Himachal Pradesh, it is not disputed that such action is pending consideration. In fact, our attention is invited to communication, dated 29th July, 2016, that of the Member Secretary, H.P. State Pollution Control Board, requesting for grant of prosecution sanction. Also, Principal Secretary (Environment Science and Technology), Government of Himachal Pradesh in his affidavit does state that matter is pending consideration with the Department of Urban Development. Why no decision stands taken till date remains unexplained. Is it that the State is actually shielding such officials/officers? Is it that in fact such officials/officers have not committed any criminal act? Or is it that State will allow status quo to continue for an unending period, unmindful of the fact that non disposal of garbage is otherwise affecting the environment and ecology, apart from the environment laws being flouted with impunity.
Under these circumstances, we direct the Chief Secretary, Government of Himachal Pradesh to ensure that the authorities concerned do take appropriate decision within next two days.::: Downloaded on - 24/04/2018 22:59:11 :::HCHP

On 26th of October, 2017, Mr. Tarun Kapoor, Additional Chief Secretary (Environment, Science and Technology), to the Government of Himachal Pradesh filed his personal affidavit informing the decision taken of not granting sanction r to prosecute the officer(s)/official(s) concerned.
Quite apparently, such decision was taken by the Additional Chief Secretary (Urban Development), to the Government of Himachal Pradesh while passing order dated 26th of October, 2017. The reasons for not granting prosecution sanction, briefly assigned are as under:-
"Now, therefore, in view of compelling reasons such as;
Multiplicity of officers having held charge of MC Chamba, over a short period of time.
Record/letters provided by the MC Parwanoo to the Director, Urban Development with respect to works/steps initiated by MC Parwanoo for sewerage connectivity and to initiate tenders to get their sewerage lines repaired.
Limited decision making authority vested in the Executive Officers of the Municipalities. Greater role of HPPCB, as enshrined in Water Act, 1974, to prevent pollution of water sources, the role of facilitator and advisor that the HPPCB is expected to play under EP Act and MSW rules, which cannot be overlooked.::: Downloaded on - 24/04/2018 22:59:11 :::HCHP
I, am of the considered opinion that prima facie steps have been initiated for sewerage and MSW/garbage .
disposal. However, action needs to be accelerated with respect to both aspects to have better and clean environment in the cities. Thus, the department is of the view that prosecution sanction against the officials of MC Chamba and MC Parwanoo under Section 197 of Cr.P.C, as sought by Member Secretary, HPPCB cannot be granted."
We notice that at least with respect to two municipal areas, i.e. Municipal Committee, Chamba and Municipal Committee, Parwanoo, the regulator i.e. Himachal Pradesh State Pollution Control Board has initiated action for taking appropriate steps against the erring officer(s)/ official(s).
Mr. Tara Singh Chauhan, learned Counsel informs that with respect to Municipal Committee, Chamba, similar endeavour, though unsuccessfully, was also made in the year 2002. However, in so far as the proposed action is concerned, the regulator emphatically wants the matter to be taken to its logical end and that being prosecution of the erring officer(s)/official(s).
Before we express any opinion on the merits of the matter, more so, order dated 26th of October, 2017, passed by the Additional Chief Secretary (UD) to the Government of Himachal Pradesh, we only direct the Chief Secretary to the Government of Himachal Pradesh, to have ::: Downloaded on - 24/04/2018 22:59:11 :::HCHP the matter examined afresh and at length, in terms of our .
earlier order dated 23.10.2017 and take appropriate decision within one week.
In Court, Mr. Tara Singh Chauhan, learned Counsel wants us to examine certain files indicating that not only the concerned erring officer(s)/official(s) were sent on tour but also sensitized and made aware of various action plans and statutory provisions pertaining to the environmental laws. Before we examine the same, it is only appropriate that the said material is placed before the appropriate authority. We direct the regulator to place additional material in support of its request for grant of prosecution sanction with the appropriate authority within a period of two days so as to enable the Chief Secretary, Government of Himachal Pradesh to take an appropriate decision.
