New Attribute: js_id. Used to uniquely identify and retrieve an object in the script file. Defaults to a unique number. Must be unique.
New Attribute: onclick. Specifies code or the name of a function to run when the object is clicked. If it's the name of a function the function can take arguments but requires nested quotes ex"example( " 'var' ")".
New Attribute: oncollision. Specifies code or the name of a function to run when this object collides with the player, it requires a collision radius to be set.
New Asset: AssetScript. Usage: See the script documentation for more details on what features are supported in a script file.
-- Multiple script files are supported, however, not with oncollision or onclick events.
-- Script language is qtScript, basically equivalent to Javascript (ECMAScript 3 standard-compliant, see http://qt-project.org/doc/qt-5/ecmascript.html for a reference on what's built-in)
-- Script is run when the asset finishes loading.
The room an its elements are accessible through the global object "room".
Read-only. Contains the url of the room.
The objects in the room. A dictionary that maps the js_id attribute of each object to a script object that has that object's attributes. Modifying the attributes of this object will modify the attributes of the object in the room.
Example:
room.object['myObjectJSId'].pos.y = 5;
A dictionary that stores state that should persist between user sessions. To add a new cookie, use the "addCookie" function.
Example:
// Code to keep track of how many times a user has visited a room. if (typeof room.cookies['visits'] == 'undefined') room.addCookie('visits', 0); room.cookies['visits'] +=1;
Creates and returns a new object in the room. "tag" should be one of the supported object tags(see notes on room contents). If "tag" is unsuppported, the object's type will default to "Object". "attributes" is a dictionary specifying the initial attributes of the object, e.g. {pos: Vector(1, 0, -1), text: "Hello World"}. The object will also be added into the "objects" dictionary. If the js_id of the object is specified in attributes, it will be used as the key, otherwise the key will be a new unique number converted to a string.
Removes an object from the room. Can be provided either the js_id of the object or the object itself.
Adds a cookie with the given name and value. The value will be converted into a string.
Plays the sound with the given asset id.
Set room walk speed. Default value: 1.8 (m/s)
Set room run speed. Default value: 5.4 (m/s)
Set room jump velocity. Default value: 5.0 (m/s)
Set room gravity.
Default value: -9.8 (m/s)
Example:
room.update = function(delta_time) { globalTime += delta_time; room.gravity = -(Math.sin(globalTime/1000.0)+1.0)*4.9; }
There are also several "callback" functions that you can define on the room, to be run when certain events happen:
Invoked before the first update of the room. Note that this is not when the room is loaded, but when the user first steps into the room.
Invoked on each frame before the world is drawn. dt, an optional parameter, is the amount of time that elapsed between this update and the previous update, useful for ensuring objects move at the same speed regardless of framerate.
Invoked twice when two objects in the room collide with each other: once with the first object as the first argument and the second object as the second agument, and once with the second object as the first argument and the first object as the second argument. Note that both elements need to have a collision radius in order to collide.
Invoked when the user releases their mouse 1 button.
Invoked when the user press down the mouse 1 button.
Invoked when the user presses a key. "event" is an object with a property "keyCode" that indicates the key that was pressed (e.g. "W", "A"), and a function "preventDefault()" that when invoked prevents the default behavior for the key press from taking place. Certain buttons don't cause an event to occur (CTRL, SHIFT, TAB). Additionally using charCodeAt(0) can be useful for keys such as ENTER & BACKSPACE
room.onKeyDown = function(event) { print(event.keyCode.charCode(0)); if(event.keyCode.charCodeAt(0)== 4) { //do something } }
The same as onKeyDown, but invoked when the user lets go of a key.
Script objects, created via room.createObject(tag, [attributes]), represent the objects that make up a room. They can be anything from images, text, sounds, links, models, etc.
Changing the attributes of a script object changes the attributes of the corresponding object in the room. Currently script objects do not support all of the attributes of regular elements. The supported attributes are:
"id", "js_id", "text", "image_id", "onclick", "oncollision".
"pos", "vel", "fwd", "xdir", "ydir", "zdir", "col", "scale". Each vector object has "x", "y", and "z" properties.
"collision_radius"
"font_size"
"player" is another global object that is instantiated before onLoad is invoked.
Similar to the objects in "room.objects", it is an object that has the player's attributes and allows you to modify them.
Note that since this is not created before the onLoad callback, this is not usable in the global scope.
Read & Write: Contains the vector of the player's current position.
Contains the vector of the player's eye position, relative to the player position.
Contains the vector of the player's cursor position.
Contains the vector of the player's x direction.
Contains the vector of the player's y direction.
Contains the vector of the player's z direction.
Contains the vector of the player's head position, relative to the eye position.
Contains the forward vector in which the player is currently looking. Useful if the player is using an HMD.
Read-only.Contains the forward vector in which the player's body is currently facing, as well as head tilt.
Read-only. Contains the userid of the player.
Read-only. Contains the url of the room the player is in.
Read-only. Boolean. True if user is using an HMD, otherwise false.
The following player properties can be read (note that all points are in *worldspace*):
Can be hand0 or 1.
Example:
if (hand0_active) { print("Hand 0 is Up!"); } else if (hand1_active) { print("Hand 1 is Up!"); }
Is the hand being tracked? (boolean, left hand)
read only hand 0 x orientation
read only hand 0 y orientation
read only hand 0 z orientation
central palm position (Vector3, left hand)
thumb endpoint position (Vector3, left hand)
index endpoint position (Vector3, left hand)
middle endpoint position (Vector3, left hand)
fourth endpoint position (Vector3, left hand)
pinky endpoint position (Vector3, left hand)
These attributes can be used e.g. to grab objects and have them oriented properly in the hand by setting the Object's xdir,ydir,zdir to the appropriate hand's xdir,ydir,zdir.
Some quick code that repeatedly shows the direction of the left hand's xdir,ydir,zdir when active:
room.update = function(delta_time) { if (hand0_active) { print('hand0_xdir: ' + player.hand0_xdir.x + ' ' + player.hand0_xdir.y + ' ' + player.hand0_xdir.z); print('hand0_ydir: ' + player.hand0_ydir.x + ' ' + player.hand0_ydir.y + ' ' + player.hand0_ydir.z); print('hand0_zdir: ' + player.hand0_zdir.x + ' ' + player.hand0_zdir.y + ' ' + player.hand0_zdir.z); } }
Scripts have access to several built-in functions for operating on the room's elements and their attributes. The functions are:
Beware: Setting a vector will cause a memory leak.Can be used as a regular function("Vector(1, 2, 3)") or as a constructor("new Vector(1, 2, 3)"). If no arguments are supplied, creates the zero vector. If a single number is provided, creates a vector with all of its components initialized to that number. If a single object is provided, creates a vector from the "x", "y", and "z" properties of that object, allowing you to clone an existing vector. Can use "V" instead of "Vector" as a shortform for convenience.
Beware: Translate function causes a memory leak. returns a new vector that is the result of adding the v1 and v2 vectors together.
Beware: Translate function causes a memory leak. returns a new vector that is the result of scalar multiplying v1 with the second argument. If the second argument is a number n, then the result is a vector with components (x1 * n, y1 * n, z1 * n). If the second argument is a vector with components (x2, y2, z2), then the result is a vector with components (x1 * x2, y1 * y2, z1 * z2).
Beware: cross function causes a memory leak. returns the cross product of v1 and v2.
Beware: normalized function causes a memory leak.returns a normalized version of the given vector.
Distance does not cause a memory leak. returns the distance between the two given points(vectors).
Removes a key-value pair from the given dictionary by key.
Logs the given value in the debugger output.
Logs the given value in the debugger output and returns it. Useful for examinining results of expressions without having to abstract them into a variable and print them.
returns a unique number that you can use, say in specifying the js_id of a new object.
- Activating debugger immediately after removing an object referenced outside the objects hash can cause a crash.
- Attempting to use the unary minus operator on a vector causes a crash.
- Comparing vectors is done by reference, not by value.

Chat Buro
Realtime pure-html chat
ChatBuro is created as a free solution to serve pure-html based chat boxes with no requirements else than the html chat snippet.
I made ChatBuro not only because i like the aesthetics of pure html/css but also because i think its amazing how far we went into the javascript rabbit hole when you can do so much without a single line of it, and i wanted to show that realtime web does not need to be complicated.
I wish you have a great time using ChatBuro, everything is opensourced on github. If you really like it a lot, consider donating.

Create chat snippet
Your chat form:
Copy it into the body of your pageExample chat
$chatburo_example_chatHow and why?
Inspired by css-only-chat i wanted to create a simple but usable realtime chat element in pure html.
I learned that i could do server push with .mjpeg which made think about using a simple html-form as user input and a motion-jpeg as live server pushed output.
To get around having to be redirected on server pushed i use a target="charburo-worker" on the form to always use the same tab/window as my form-post target.
With all this i now had:
1. an img that shoed live info from the server
2. an input form for submitting messages myself
Next step was to create the backend for this, here i created a simple docker-compose POC based around python/sanic for web api and KeyDB (faster redis) for pubsub.
The last step was to figure out a way to make chatrooms that only responded to requests from a certain url, here i used json web tokens to embed a trusted origin into the hash of the chat url.

## About Defenestrate is a newly formed guild located on Tarren mill intent on maintaining a 2 day a week raiding guild while keeping up with irl at the same time. We are currently 4/9 Mythic and are prepairing for Antorus. Our aim is cutting edge, to achieve this we will be raiding two days a week, Monday and Thursday.
We prefer people to have as close to 100% attendance as possible for raids, however we understand that real life is always priority.
All loot is distributed, via a 3 man loot council, with all loot being awarded to the player able to most benefit from said loot.
We're currently recruiting talented players to join our ranks in preparation for Antorus, the burning throne. Please see our Contact Section for our current recruitment options.

A brief stint playing with clojure made me miss common lisp, so I’m working
through Paul Graham’s
ANSI Common Lisp with a copy of
On Lisp. My last foray, I learned
from David Touretzky’s
A Gentle Introduction to Symbolic Computation,
so this time I’m trying PG’s book. So far I’ve done more useful things,
mostly by actually reading a bit more of the sbcl
user manual (from which I learned some
useful things such as sb-ext:*posix-argv*
and sb-ext:save-lisp-and-die
)
and by the immensely useful site
Rosetta Code, from which I
learned about the DRAKMA HTTP client
library. I’ve also been aided quite a bit by
Zach Beane’s quicklisp;
in fact, one of the things I’ve done is to write a short
script to build an sbcl image with
quicklisp and my most commonly used libraries built-in.
One of the things I love about functional programming is the idea that instead of relying on a lot of variables, you use functions as sort of “organic variables” that provide immutable data based on some input. The ability to build what feels more organic, less static. I think Steve Yegge’s blog post Execution in the Kingdom of Nouns is spot on.
I anticipate this to be the year of Lisp for me, as I delve into Common Lisp, Scheme, and Clojure.

Authors: Prof. Per-Simon Kilda
Source: FERMAT, Volume 11, Communications 4, Sep_Oct, 2015
Introductory Text: • I defined “soft and hard surfaces” in 1988. These were a generalization of the corrugated surfaces. Today we represent them ideally as canonical PEC/PMC strip grids, realized as metasurfaces.
• The simple and conceptual generalization made it easier to see new applications, and these came in terms of inventions. The patented hat antenna with a corrugated “soft” brim has been as a feed in a reflector antenna manufactured in more than 1 million copies for use in radio links.
• The soft surface is anisotropic, but has otherwise the same characteristics as an EBG surface. It stops waves from propagating along the surface. Thus, it is a forerunner of the EBG surface.
• I used the hard surface to make struts invisible in 1988 (i.e. to reduce forward scattering, also referred to as superstealth). The journal article was published in 1996, ten years before the first cloaking paper appeared. Thus, the hard struts was really the first cloaking concept, and they worked in practice over 20% bandwidth, for any polarization of an incident wave with given angle of arrival.
• The soft and hard surfaces have been used in many antenna applications and realized in many ways since 1988. • This conceptual thinking resulted in the definition of gap waveguides in 2009. Gap waveguides are waveguides realized in a narrow air gap between parallel plates, by using a texture in one of the plates. The wave propagation is controlled by designing a stopband for normal parallel-plate modes, and allowing the waves to propagate along ridges, grooves or microstrips. This gives ridge, groove and microstrip gap waveguides.
• The stopband appears ideally those places where one of the surfaces is a PEC and the other a PMC. The gap between a PEC and a PMC cannot support any waves when it is narrower than quarter of the wavelength.
• We have since 2009 researched the gap waveguide to a competitive waveguide technology for wideband millimeterwave applications, including low loss transmission lines, high-Q filters, transitions, resonance-free EM packaging of microstrip and co-planar waveguide circuits and MMICs, distribution networks and directive antennas. The industrial applications are approaching.
• The present slides give an introduction to these concepts.
• Some selected references are given at the end.
• Many more references on gap waveguides can be found in the following book chapter: – A. Uz Zaman, P.-S. Kildal, “Gap Waveguides”, to appear in Handbook of Antenna Technologies, Springer 2016.
• The soft and hard surfaces and gap waveguides are lectured in the course on “Metasurfaces for Antennas” organized by European School of Antennas every third year. The next appearance is 5-9 October 2015 in Zagreb.

What is special about government bonds?
Bonds typically pay coupons of fixed cash amounts. Equites, on the other hand, pay dividends whose size may depend on many factors, such as the issuer's profits. This dependence introduces an element of risk which makes the pricing of equites more complicated than the pricing of bonds.
-
What does 'asset pricing' mean?
Although asset prices are decided by the parties to a trade we have some methods (called 'models') for deciding what a 'fair' price would be. By 'asset pricing' we mean using these methods to find the 'fair' price.
-
A simple example
The most straightforward example is probably that of a Treasury bill. If the 1-year interest rate is $r_1$ then we should expect the price of a 1-year Treasury bill to be $p_1 = \frac{100}{1+r_1}$.
-
A more advanced example
Asset pricing models can get a bit more complicated! Here's the Black-Scholes option price equation: $p = SN(d_1) - N(d_2)Ke^{-rt}$ We do not focus on this one here.
How much should we pay today to receive money in the future?
This is the key question: If we have a contract that states that 1 year from now whoever owns the contract will receive £100, how much should we expect to be able to sell that contract for today? A related question is "Why could we not get £100 for it today?"
-
Delay aversion
It is generally assumed that £100 to be received 1 year in the future is worth less to us than £100 in hand today. One reason for this is that the £100 we hold today, unlike the £100 in the future, can be spent at any time during the coming year.
-
Risk aversion
There is usually a risk that the contract will not be honoured. So if a potential buyer can put their £100 in an FSCS-protected bank deposit, even if it pays no interest they are unlikely to want to buy the contract for that amount, given that they might not get anything back.
-
Combining the aversions
Asset pricing models take account of aversion to both delay and risk. So pricing equations are just mathematical versions of the followng function: $p = f(\mbox{waiting time},\mbox{risk})$
Discounting a safe future payment
If we can invest £k for 1 year at $r$% our return (call it $W$) will be:
$W = k(1+r)$
Similarly, if we have to pay someone $£W$ in a year we can finance this by depositing $£k$ today where:
\[k = \frac{W}{1+r}\]
Discounting over 2 years.
If we have a payment due in 2 years we can disount it twice: first from 2 years to 1 year, to give a notional value 1 year from now, the we discount that value back to today.
So we get \[k = \frac{1}{1+r} \times \frac{W}{1+r} = \frac{W}{(1+r)^2}\]

Burakovsky stars as Avalanche cling on to beat Calgary Flames
by Darren HaynesAndre Burakovsky stayed red-hot with another two goals on Tuesday night, leading the Colorado Avalanche to a 3-2 victory over the slumping Calgary Flames.
That’s five goals in the last three games for the 24-year-old left-winger, who on this night took advantage of a promotion to the top line and a chance to line up alongside Nathan MacKinnon and Joonas Donskoi.
MacKinnon assisted on both Burakovsky goals to give him 13 points (5 goals, 8 assists) in his last six games.
Vladislav Kamev also scored for Colorado (13-6-2), which has won five of its last six. The Avalanche improve to 3-1-0 on a five-game road trip that wraps up on Thursday in Minnesota.
Derek Ryan and Andrew Mangiapane scored for Calgary (10-11-3). The slumping Flames are winless in their last five — the last four losses coming in regulation.
Philipp Grubauer got the win in his first game back after missing five games with a lower-body injury. He had 31 stops to improve to 7-3-2. David Rittich had 23 saves for the Flames. His record fell to 9-6-3.
The Avs opened the scoring 3:21 into the first period when Burakovsky took a cross-ice pass from MacKinnon and fired a shot just inside the post.
Before the first period was over, Burakovsky made it 2-0 at 18:45 with his 10th of the season. Off a faceoff win by MacKinnon in the Flames end, the Swede got the puck along the sideboards, cut back sharply to get some separation on defenceman Rasmus Andersson and ripped a shot under the crossbar.
The 2-0 lead for the Avs came despite being outshot 13-7.
After Kamenev, set up by J.T. Compher on a 2-on-1, made it 3-0 at 13:15, the Flames finally got on the scoreboard at 17:41 of the second, Ryan beating Grubauer under the crossbar.
The goal ended a shutout streak of 167 minutes and 44 seconds, dating back to the third period against Dallas on Nov. 13. Calgary was shut out in both games on its weekend road trip to Arizona and Vegas.
Setting up a furious finish, the Flames drew within one on Mangiapane’s fourth goal at 15:44 of the third. But despite getting a power play for the last 21 seconds and having the goalie pulled, they could not take advantage of the 6-on-4.

Create a simple microservice using Lambda and API Gateway
In this tutorial you will use the Lambda console to create a Lambda function, and
an Amazon API Gateway endpoint to trigger
that function. You will be able to call the endpoint with any method (GET
, POST
,
PATCH
, etc.) to trigger your Lambda function. When the endpoint is called, the entire request
will be
passed through to your Lambda function. Your function action will depend on the method
you call your endpoint with:
-
DELETE: delete an item from a DynamoDB table
-
GET: scan table and return all items
-
POST: Create an item
-
PUT: Update an item
Create an API using Amazon API Gateway
Follow the steps in this section to create a new Lambda function and an API Gateway endpoint to trigger it:
To create an API
-
Sign in to the AWS Management Console and open the AWS Lambda console.
-
Choose Create Lambda function.
-
Choose Blueprint.
-
Enter
microservice
in the search bar. Choose the microservice-http-endpoint blueprint and then choose Configure. -
Configure the following settings.
-
Name –
lambda-microservice
. -
Role – Create a new role from AWS policy templates.
-
Role name –
lambda-apigateway-role
. -
Policy templates – Simple microservice permissions.
-
API – Create a new API.
-
Security – Open.
Choose Create function.
-
When you complete the wizard and create your function, Lambda creates a proxy resource
named
lambda-microservice
under the API name you selected. For more information about proxy resources,
see Configure proxy integration for a proxy
resource.
A proxy resource has an AWS_PROXY
integration type and a catch-all method ANY
. The
AWS_PROXY
integration type applies a default mapping template to pass through the entire request
to
the Lambda function and transforms the output from the Lambda function to HTTP responses.
The ANY
method defines the same integration setup for all the supported methods, including
GET
,
POST
, PATCH
, DELETE
and others.
Test sending an HTTP request
In this step, you will use the console to test the Lambda function. In addition, you
can run a
curl
command to test the end-to-end experience. That is, send an HTTP request to your API method
and have Amazon API Gateway invoke your Lambda function. In order to complete the
steps, make sure you have created a DynamoDB
table and named it "MyTable". For more information, see Create a DynamoDB table with a stream enabled
To test the API
-
With your
lambda-microservice
function still open in the console, in the upper right hand corner of the console, choose Test. -
In Event name, enter a name for the test event.
-
In the text entry panel, replace the existing text with the following:
{ "httpMethod": "GET", "queryStringParameters": { "TableName": "MyTable" } }
-
After entering the text above choose Create.
-
Choose the event that you created and choose Test.
