3 lessonsLorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Detailed Description
The Context2D object can be created by Canvas
item's getContext()
method:
Canvas { id:canvas onPaint:{ var ctx = canvas.getContext('2d'); //... } }
The Context2D API implements the same W3C Canvas 2D Context API standard with some enhanced features.
The Context2D API provides the rendering context which defines the methods and attributes needed to draw on the Canvas
item. The following assigns the canvas rendering context to a context
variable:
var context = mycanvas.getContext("2d")
The Context2D API renders the canvas as a coordinate system whose origin (0,0) is at the top left corner, as shown in the figure below. Coordinates increase along the x
axis from left to right and along the y
axis from top to bottom of the canvas.
Property Documentation
canvas : QtQuick::Canvas |
Holds the canvas item that the context paints on.
This property is read only.
Holds the current fill rule used for filling shapes. The following fill rules supported:
- Qt.OddEvenFill
- Qt.WindingFill
Note: Unlike the QPainterPath, the Canvas API uses the winding fill as the default fill rule. The fillRule property is part of the context rendering state.
See also fillStyle.
fillStyle : variant |
Holds the current style used for filling shapes. The style can be either a string containing a CSS color, a CanvasGradient or CanvasPattern object. Invalid values are ignored. This property accepts several color syntaxes:
- 'rgb(red, green, blue)' - for example: 'rgb(255, 100, 55)' or 'rgb(100%, 70%, 30%)'
- 'rgba(red, green, blue, alpha)' - for example: 'rgb(255, 100, 55, 1.0)' or 'rgb(100%, 70%, 30%, 0.5)'
- 'hsl(hue, saturation, lightness)'
- 'hsla(hue, saturation, lightness, alpha)'
- '#RRGGBB' - for example: '#00FFCC'
- Qt.rgba(red, green, blue, alpha) - for example: Qt.rgba(0.3, 0.7, 1, 1.0)
If the fillStyle
or strokeStyle is assigned many times in a loop, the last Qt.rgba() syntax should be chosen, as it has the best performance, because it's already a valid QColor value, does not need to be parsed everytime.
The default value is '#000000'.
See also createLinearGradient(), createRadialGradient(), createPattern(), and strokeStyle.
Holds the current font settings.
A subset of the w3C 2d context standard for font is supported:
- font-style (optional): normal | italic | oblique
- font-variant (optional): normal | small-caps
- font-weight (optional): normal | bold | 0 ... 99
- font-size: Npx | Npt (where N is a positive number)
- font-family: See http://www.w3.org/TR/CSS2/fonts.html#propdef-font-family
Note: The font-size and font-family properties are mandatory and must be in the order they are shown in above. In addition, a font family with spaces in its name must be quoted.
The default font value is "10px sans-serif".
Holds the current alpha value applied to rendering operations. The value must be in the range from 0.0
(fully transparent) to 1.0
(fully opaque). The default value is 1.0
.
Holds the current the current composition operation, from the list below:
- source-atop - A atop B. Display the source image wherever both images are opaque. Display the destination image wherever the destination image is opaque but the source image is transparent. Display transparency elsewhere.
- source-in - A in B. Display the source image wherever both the source image and destination image are opaque. Display transparency elsewhere.
- source-out - A out B. Display the source image wherever the source image is opaque and the destination image is transparent. Display transparency elsewhere.
- source-over - (default) A over B. Display the source image wherever the source image is opaque. Display the destination image elsewhere.
- destination-atop - B atop A. Same as source-atop but using the destination image instead of the source image and vice versa.
- destination-in - B in A. Same as source-in but using the destination image instead of the source image and vice versa.
- destination-out - B out A. Same as source-out but using the destination image instead of the source image and vice versa.
- destination-over - B over A. Same as source-over but using the destination image instead of the source image and vice versa.
- lighter - A plus B. Display the sum of the source image and destination image, with color values approaching 255 (100%) as a limit.
- copy - A (B is ignored). Display the source image instead of the destination image.
- xor - A xor B. Exclusive OR of the source image and destination image.
Additionally, this property also accepts the compositon modes listed in QPainter::CompositionMode. According to the W3C standard, these extension composition modes are provided as "vendorName-operationName" syntax, for example: QPainter::CompositionMode_Exclusion is provided as "qt-exclusion".
Holds the current line cap style. The possible line cap styles are:
- butt - the end of each line has a flat edge perpendicular to the direction of the line, this is the default line cap value.
- round - a semi-circle with the diameter equal to the width of the line must then be added on to the end of the line.
- square - a rectangle with the length of the line width and the width of half the line width, placed flat against the edge perpendicular to the direction of the line.
Other values are ignored.
Holds the current line join style. A join exists at any point in a subpath shared by two consecutive lines. When a subpath is closed, then a join also exists at its first point (equivalent to its last point) connecting the first and last lines in the subpath.
The possible line join styles are:
- bevel - this is all that is rendered at joins.
- round - a filled arc connecting the two aforementioned corners of the join, abutting (and not overlapping) the aforementioned triangle, with the diameter equal to the line width and the origin at the point of the join, must be rendered at joins.
- miter - a second filled triangle must (if it can given the miter length) be rendered at the join, this is the default line join style.
Other values are ignored.
Holds the current line width. Values that are not finite values greater than zero are ignored.
Holds the current shadow offset in the positive horizontal distance.
See also shadowOffsetY.
Holds the current shadow offset in the positive vertical distance.
See also shadowOffsetX.

Holds the current color or style to use for the lines around shapes, The style can be either a string containing a CSS color, a CanvasGradient or CanvasPattern object. Invalid values are ignored.
The default value is '#000000'.
See also createLinearGradient(), createRadialGradient(), createPattern(), and fillStyle.
Holds the current text alignment settings. The possible values are:
- start
- end
- left
- right
- center
Other values are ignored. The default value is "start".
Holds the current baseline alignment settings. The possible values are:
- top

- ideographic
- bottom
Other values are ignored. The default value is "alphabetic".
Method Documentation
Adds an arc to the current subpath that lies on the circumference of the circle whose center is at the point (x, y) and whose radius is radius.
Both startAngle
and endAngle
are measured from the x-axis in radians.
The anticlockwise parameter is true
for each arc in the figure above because they are all drawn in the anticlockwise direction.
See also arcTo and W3C's 2D Context Standard for arc().
Adds an arc with the given control points and radius to the current subpath, connected to the previous point by a straight line. To draw an arc, you begin with the same steps you followed to create a line:
- Call the beginPath() method to set a new path.
- Call the moveTo(
x
,y
) method to set your starting position on the canvas at the point (x
,y
). - To draw an arc or circle, call the arcTo(x1, y1, x2, y2, radius) method. This adds an arc with starting point (x1, y1), ending point (x2, y2), and radius to the current subpath and connects it to the previous subpath by a straight line.
See also arc and W3C's 2D Context Standard for arcTo().
Adds a cubic bezier curve between the current position and the given endPoint using the control points specified by (cp1x
, cp1y), and (cp2x
, cp2y
). After the curve is added, the current position is updated to be at the end point (x
, y
) of the curve. The following code produces the path shown below:
ctx.strokeStyle = Qt.rgba(0, 0, 0, 1); ctx.lineWidth = 1; ctx.beginPath(); ctx.moveTo(20, 0);//start point ctx.bezierCurveTo(-10, 90, 210, 90, 180, 0); ctx.stroke();
See also W3C 2d context standard for bezierCurveTo and The beautiful flower demo by using bezierCurveTo.
Clears all pixels on the canvas in the given rectangle to transparent black.
Creates the clipping region from the current path. Any parts of the shape outside the clipping path are not displayed. To create a complex shape using the clip()
method:
- Call the
context.beginPath()
method to set the clipping path. - Define the clipping path by calling any combination of the
lineTo
,arcTo
,arc
,moveTo
, etc andclosePath
methods. - Call the
context.clip()
method.
The new shape displays. The following shows how a clipping path can modify how an image displays:
See also beginPath(), closePath(), stroke(), fill(), and W3C 2d context standard for clip.
Closes the current subpath by drawing a line to the beginning of the subpath, automatically starting a new path. The current point of the new path is the previous subpath's first point.
See also W3C 2d context standard for closePath.
Returns a CanvasGradient object that represents a conical gradient that interpolate colors counter-clockwise around a center point (x
, y
) with start angle angle
in units of radians.
See also CanvasGradient::addColorStop(), createLinearGradient(), createRadialGradient(), createPattern(), fillStyle, and strokeStyle.
CanvasImageData createImageData(Url imageUrl) |
Creates a CanvasImageData object with the given image loaded from imageUrl.
Note: The imageUrl must be already loaded before this function call, otherwise an empty CanvasImageData obect will be returned.
See also Canvas::loadImage(), QtQuick::Canvas::unloadImage(), and QtQuick::Canvas::isImageLoaded.
CanvasImageData createImageData(CanvasImageData imageData) |
Creates a CanvasImageData object with the same dimensions as the argument.
CanvasImageData createImageData(real sw, real sh) |
Creates a CanvasImageData object with the given dimensions(sw, sh).
Returns a CanvasGradient object that represents a linear gradient that transitions the color along a line between the start point (x0, y0) and the end point (x1, y1).
A gradient is a smooth transition between colors. There are two types of gradients: linear and radial. Gradients must have two or more color stops, representing color shifts positioned from 0 to 1 between to the gradient's starting and end points or circles.
See also CanvasGradient::addColorStop(), createRadialGradient(), createConicalGradient(), createPattern(), fillStyle, and strokeStyle.
Returns a CanvasPattern object that uses the given image and repeats in the direction(s) given by the repetition argument.
The image parameter must be a valid Image item, a valid CanvasImageData object or loaded image url, if there is no image data, throws an INVALID_STATE_ERR exception.
The allowed values for repetition are:
- "repeat" - both directions
- "repeat-x - horizontal only
- "repeat-y" - vertical only
- "no-repeat" - neither
If the repetition argument is empty or null, the value "repeat" is used.
See also strokeStyle and fillStyle.
variant createPattern(color color, enumeration patternMode) |
This is a overload function. Returns a CanvasPattern object that uses the given color and patternMode. The valid pattern modes are:
- Qt.SolidPattern
- Qt.Dense1Pattern
- Qt.Dense2Pattern
- Qt.Dense3Pattern
- Qt.Dense4Pattern
- Qt.Dense5Pattern
- Qt.Dense6Pattern
- Qt.Dense7Pattern
- Qt.HorPattern
- Qt.VerPattern
- Qt.CrossPattern
- Qt.BDiagPattern
- Qt.FDiagPattern
- Qt.DiagCrossPattern
See also Qt::BrushStyle.
Returns a CanvasGradient object that represents a radial gradient that paints along the cone given by the start circle with origin (x0, y0) and radius r0, and the end circle with origin (x1, y1) and radius r1.
See also CanvasGradient::addColorStop(), createLinearGradient(), createConicalGradient(), createPattern(), fillStyle, and strokeStyle.
drawImage(variant image, real sx, real sy, real sw, real sh, real dx, real dy, real dw, real dh) |
This is an overloaded function. Draws the given item as image from source point (sx, sy) and source width sw, source height sh onto the canvas at point (dx, dy) and with width dw, height dh.
Note: The image type can be an Image or Canvas item, an image url or a CanvasImageData object. When given as Image item, if the image isn't fully loaded, this method draws nothing. When given as url string, the image should be loaded by calling Canvas item's Canvas::loadImage() method first. This image been drawing is subject to the current context clip path, even the given image
is a CanvasImageData object.
See also CanvasImageData, Image, Canvas::loadImage(), Canvas::isImageLoaded, Canvas::imageLoaded, and W3C 2d context standard for drawImage.
drawImage(variant image, real dx, real dy, real dw, real dh) |
This is an overloaded function. Draws the given item as image onto the canvas at point (dx, dy) and with width dw, height dh.
Note: The image type can be an Image item, an image url or a CanvasImageData object. When given as Image item, if the image isn't fully loaded, this method draws nothing. When given as url string, the image should be loaded by calling Canvas item's Canvas::loadImage() method first. This image been drawing is subject to the current context clip path, even the given image
is a CanvasImageData object.
See also CanvasImageData, Image, Canvas::loadImage(), Canvas::isImageLoaded, Canvas::imageLoaded, and W3C 2d context standard for drawImage.
drawImage(variant image, real dx, real dy) |
Draws the given image on the canvas at position (dx, dy). Note: The image type can be an Image item, an image url or a CanvasImageData object. When given as Image item, if the image isn't fully loaded, this method draws nothing. When given as url string, the image should be loaded by calling Canvas item's Canvas::loadImage() method first. This image been drawing is subject to the current context clip path, even the given image
is a CanvasImageData object.
See also CanvasImageData, Image, Canvas::loadImage, Canvas::isImageLoaded, Canvas::imageLoaded, and W3C 2d context standard for drawImage.
Creates an ellipse within the bounding rectangle defined by its top-left corner at (x, y), width w and height h, and adds it to the path as a closed subpath.
The ellipse is composed of a clockwise curve, starting and finishing at zero degrees (the 3 o'clock position).
Fills the subpaths with the current fill style.
See also W3C 2d context standard for fill and fillStyle.
Fills the given text at the given position.
See also font, textAlign, textBaseline, and strokeText.
CanvasImageData getImageData(real sx, real sy, real sw, real sh) |
Returns an CanvasImageData object containing the image data for the given rectangle of the canvas.
Returns true if the given point is in the current path.
Returns an object with a width
property, whose value is equivalent to calling QFontMetrics::width() with the given text in the current font.
object putImageData(CanvasImageData imageData, real dx, real dy, real dirtyX, real dirtyY, real dirtyWidth, real dirtyHeight) |
Paints the data from the given ImageData object onto the canvas. If a dirty rectangle (dirtyX, dirtyY, dirtyWidth, dirtyHeight) is provided, only the pixels from that rectangle are painted.
Adds a quadratic bezier curve between the current point and the endpoint (x
, y
) with the control point specified by (cpx
, cpy
).
Adds a rectangle at position (x
, y
), with the given width w
and height h
, as a closed subpath.
Reset the transformation matrix to the default value (equivalent to calling setTransform(1
, 0
, 0
, 1
, 0
, 0
)).
See also transform(), setTransform(), and reset().
Pops the top state on the stack, restoring the context to that state.
See also save().
Rotate the canvas around the current origin by angle in radians and clockwise direction.
ctx.rotate(Math.PI/2);
The rotation transformation matrix is as follows:
where the angle of rotation is in radians.
Adds the given rectangle rect with rounded corners to the path. The xRadius
and yRadius
arguments specify the radius of the ellipses defining the corners of the rounded rectangle.
Pushes the current state onto the state stack.
Before changing any state attributes, you should save the current state for future reference. The context maintains a stack of drawing states. Each state consists of the current transformation matrix, clipping region, and values of the following attributes:
- strokeStyle
- fillStyle
- fillRule
- globalAlpha
- lineWidth
- lineCap
- lineJoin
- miterLimit
- shadowOffsetX
- shadowOffsetY
- shadowBlur
- shadowColor
- globalCompositeOperation
- font
- textAlign
- textBaseline
The current path is NOT part of the drawing state. The path can be reset by invoking the beginPath() method.
Increases or decreases the size of each unit in the canvas grid by multiplying the scale factors to the current tranform matrix. x is the scale factor in the horizontal direction and y is the scale factor in the vertical direction.
The following code doubles the horizontal size of an object drawn on the canvas and halves its vertical size:
ctx.scale(2.0, 0.5);
Changes the transformation matrix to the matrix given by the arguments as described below.
Modifying the transformation matrix directly enables you to perform scaling, rotating, and translating transformations in a single step.
Each point on the canvas is multiplied by the matrix before anything is drawn. The HTML Canvas 2D Context specification defines the transformation matrix as:
where:
a
is the scale factor in the horizontal (x) directionc
is the skew factor in the x directione
is the translation in the x directionb
is the skew factor in the y (vertical) directiond
is the scale factor in the y directionf
is the translation in the y direction- the last row remains constant
The scale factors and skew factors are multiples; e
and f
are coordinate space units, just like the units in the translate(x,y) method.
See also transform().
Shears the transformation matrix by sh in the horizontal direction and sv in the vertical direction.
Strokes the subpaths with the current stroke style.
See W3C 2d context standard for stroke
See also strokeStyle.
Stroke the specified rectangle's path using the strokeStyle, lineWidth, lineJoin, and (if appropriate) miterLimit attributes.
See also strokeStyle, lineWidth, lineJoin, and miterLimit.
Strokes the given text at the given position.
See also font, textAlign, textBaseline, and fillText.
Adds the given text
to the path as a set of closed subpaths created from the current context font supplied. The subpaths are positioned so that the left end of the text's baseline lies at the point specified by (x
, y
).
This method is very similar to setTransform(), but instead of replacing the old transform matrix, this method applies the given tranform matrix to the current matrix by multiplying to it.
The setTransform(a, b, c, d, e, f) method actually resets the current transform to the identity matrix, and then invokes the transform(a, b, c, d, e, f) method with the same arguments.
See also setTransform().
Translates the origin of the canvas by a horizontal distance of x, and a vertical distance of y, in coordinate space units.
Translating the origin enables you to draw patterns of different objects on the canvas without having to measure the coordinates manually for each shape.

Person shot, injured by police on Las Vegas airport tarmac
LAS VEGAS (AP) — Authorities say a person was shot and injured by Las Vegas police on a tarmac next to a terminal at McCarran International Airport.
A police statement says a person described as a suspect was hit in the shooting at about 4 a.m. Thursday and that preliminary information indicated that no officers were injured.
The police statement gave no details about the circumstances of the shooting or why the person was considered a suspect.
Airport spokesman Chris Jones the shooting happened on a tarmac between A and B gates at Terminal 1.
He says the injured person was a male and was taken to a hospital.
Carriers using that terminal include American Airlines, Allegiant Air, Delta Air Lines, Southwest Airlines, Spirit Airlines and Contour Airlines.


Usually, code that is commented out gets outdated very quickly and becomes misleading. As most projects use some kind of version control system, it is better to delete commented out code completely and use the VCS history instead.

This is a request for space by the hour only. Email<EMAIL_ADDRESS>for private studio space requests.
* Required
Name*

Which date(s) and time(s) do you need space?* e.g. Monday Jan 1 from 4-6pm
Which space are you requesting?
What type of activity are your requesting space for?*
Include what kind of dance/theater/other rehearsal/class. If you're proposing a class or workshop, what qualifications do you have; is this open to the public? etc.


using System;
namespace HelloWorld
{
class Program
{
static void Main()
{
Console.WriteLine("Hello world!");
}
}
}
Let's find out what this code means.
using System;
This allows us to use Console.WriteLine
instead of System.Console.WriteLine
. (And
for many more)
namespace HelloWorld
{
// ...
}
This isn't required, but this requires qualification or using
. For example,
System
is a namespace.
class Program
{
// ...
}
All of your code must be in a class. For your code to run, the class must be called Program
.
static void Main(string[] args) {
// ...
}
This defines a static function Main where you have access to arguments and usually don't call long-running methods. We will go over what this means later, but just think of it as required code.
If you programmed in VB.NET before, here's the code in VB:
Imports System
Module HelloWorld
Sub Main()
Console.WriteLine("Hello World")
End Sub
End Module
I won't tell you what maps to what, you figure it out yourself as an exercise.

- RecordRTC-to-Socket.io (used ffmpeg to merge wav/webm in single WebM container)
- RecordRTC and ffmpeg-asm.js (ffmpeg inside the browser!)
- Both files are recorded and uploaded individually (wav/webm)
- You can merge/mux them in single format like avi or mkv — using tools like ffmpeg/avconv
How to save recorded wav/webm file to PHP server?
- Write a PHP file to write recrded blob on disk
- Write Javascript to POST recorded blobs to server using XHR2/FormdData
PHP Code
<?php foreach(array('video', 'audio') as $type) { if (isset($_FILES["${type}-blob"])) { $fileName = $_POST["${type}-filename"]; $uploadDirectory = "uploads/$fileName"; if (!move_uploaded_file($_FILES["${type}-blob"]["tmp_name"], $uploadDirectory)) { echo("problem moving uploaded file"); } echo($uploadDirectory); } } ?>

Possible issues/failures:
The biggest issue is that RecordRTC is
unable to record both audio and video streams in single file.
Do you know "RecordRTC" fails recording audio because following conditions fails:
- Sample rate and channel configuration must be the same for input and output sides on Windows i.e. audio input/output devices must match
- Only the Default microphone device can be used for capturing.
- The requesting scheme is must be one of the following: http, https, chrome, extension's, or file (only works with --allow-file-access-from-files)
- The browser must be able to create/initialize the metadata database for the API under the profile directory

We have released a lot of information over that last few months about MonkeySpace. For those that do not follow the @MonkeySquareOrg or @MonkeySpaceConf twitter accounts, we thought it would be a good time to send an email out to get everybody updated.
We're happy to announce that MonkeySpace 2013 will be held at Columbia College in Chicago, IL from July 22-25. If you didn't notice, we added a day to pack even more content into the conference. Come join us, we'd be happy to have you. If you're on the fence, we've released promotional videos. They capture the energy, shows how approachable people are, and communicates our mission very well!
The early bird price is $250 and is available until May 15. Starting May 16, the ticket price goes up to $300. We also brought back student pricing by offering tickets for $99 to any active student. You can view the process by clicking the "Ticket Information" link under the "Register Now" button.
We also just opened the Call for Proposals. If you are interested in speaking at an event and have knowledge in cross-platform and open-source development in .NET/Mono, then we're the conference for you. All speaker levels are encouraged to submit, we had quite a few first time speakers at last years event!
MonkeySpace also has a hackfest to allow open-source developers to come together and develop on their preferred projects. We did this last year and it was a huge success! This year, we're going to take it a step forward. Once the hackfest is over or if you just want to show off your project, we're going to provide space for you to do just that! Please contact us at<EMAIL_ADDRESS>if you wish to participate this year.
If you're an open-source project owner and want to have a little sub-community event as well, we reserved a day for you. On Jul 26th, you can use the venue for free to continue work from the hackfest or have a sub-community get together to discuss the future of your project in one location. Please contact us at<EMAIL_ADDRESS>if you wish to take advantage of this day. Also if you plan on attending, you may want to plan to stay Jul 26th as well.

This is the most exciting time to be a JavaScript developer, and it is only going to get better.
Due to the advent of HTML5, the abandonment of Flash, the popularity of mobile devices, and most certainly because of Node.js, JavaScript is becoming the language of choice today and unquestionably for the near future.Node.js is made up of
Node.js itself is open source and on GitHub
The majority of Node.js is actualy written in JavaScript and the abstraction layer mostly in C and C++
Node.js runs JavaScript by leveraging V8, Google’s fast JavaScript engine designed for Chrome.
This allows Node.js to create a runtime environment that translates JavaScript into native machine language, instead of working overtime to interpret it as bytecode, giving Node.js its speed.
In a nutshell the Node.js environment provides a JavaScript interaction layer to underlying systems calls.
Node.js, uses an event loop instead of threads JavaScript is extremely well suited to event-based programming because it has anonymous functions and closures, and JavaScript developers already know how to program in this way.
This event-based model makes Node.js very fast, and able to scale to millions of concurrent connections very easy.
Node takes advantage of the fact that usualy, servers spend most of their time waiting for I/O.
For Example: Traditional approach
Every I/O operation in Node.js is (can be) asynchronous, meaning that the server can continue to process other things while the I/O operations, like reading a file from a hard drive, accessing an external web service or querying a database, are completed.
For Example: No blocking approach
Node.js uses a module architecture to simplify the creation of complex applications.
Modules are encapsulated pieces of code akin to libraries or classes. Each module contains a set of functions related to the subject of the module. For example, the http module contains functions specific to HTTP.
Node.js provides a few core modules out of the box to help you access files on the file system, create HTTP and TCP/UDP servers, and perform other useful functions.
To include a precomposed module the require() function is used as such:
var http = require('http');
In the previous code, we passed the name of a module to the require() function. This causes Node to search for a node_modules folder in our application’s directory, and search for the http module in that folder.
If Node does not find the node_modules folder (or the http module within it), it then looks through the global module cache.
You can also specify an actual file by passing a relative or absolute path, like so:
var myModule = require('./myModule.js');
NPM (Node Package Manager). Is the default package manager and is automatically installed with Node.js.
To install a module, open your terminal/command line, navigate to the desired folder, and execute the following command:
npm install module_name
It doesn’t matter what OS you have the above command will install the module you specify.
Node.js is the immediate and near future of modern web application development with JavaScript as the sole server-side language.
While Node.js, is predominantly thought of in relation to web, it is however also very good for creating command line tooling that will work accross multiple platforms. (Windows, Linux and OSX)
Combine this with the power of npm and you have a cross platform package manager to install cross platform tooling!
Great another new shiny tech that I can't use because all our existing bussiness logic is not going to be rewritten.
As .NET developers you can start using node today with your existing code.
Edge.js is a node module written by Tomasz Janczuk (@tjanczuk) and is on github here.
Edge.js connects Node.js and .NET and allows the 2 technologies to run in the same process.
There is a great presentation on Edge.js by Tomasz himself here
Tomasz says Edge.js connects all the below in one process
It does this by providing an async, in-process calling convention between the CLR and node.
There are a number of ways (some kinda crazy...) to use Edge.js, but I would only reccomend binding to a precompiled assembly.
var hello = require('edge').func({ assemblyFile: 'MyApplication.dll', typeName: 'MyApplication.MyType', methodName: 'MyMethod' }); hello('World!', function (error, result) { ... });
The graph below compares the latency of a call from Node.js to C# made in-process using edge.js vs the latency of a localhost HTTP call between 2 processes.
In both cases the caller invokes .NET function that returns about 22KB of JSON data.


Modules
Every top-level definition is visible throughout the file it is contained, the order of definitions does not matter. The module system allows you to provide definitions in other namespaces.
Modules
A module consists of a name and a list of definitions:
\module Mod \where {
def_1
...
def_n
}
You can refer to definitions def_1 … def_n inside module Mod by their names. To refer to them outside this module, you need to use their full names Mod.def_1 … Mod.def_n. For example, consider the following code:
\func f2 => Mod.f1
\module Mod \where {
\func f1 => f2
\func f2 => 0
\func f3 => f4
}
\func f4 => f2
You cannot refer to f1 in f2 without Mod. prefix. Function f4 refers to f2 defined on the top level. Function Mod.f2 hides the top level f2 inside module Mod, so Mod.f1 refers to Mod.f2. You can refer to top level functions inside modules as shown in the example where Mod.f3 refers to f4.
If a \where block contains only one definition, curly braces around it can be omitted.
\module Mod \where
\func f1 => 0
Where blocks
Every definition has an associated module with the same name. To add definitions to this module, you can write the \where block at the end of this definition. Definitions defined in the associated module of a definition are visible inside this definition.
\func f => g \where \func g => 0
\func h => f.g \where
\data D \where {
\func k => D
\func s => M.g.N.s
}
\module M \where
\func g => N.s \where {
\module N \where {
\func s => E
}
\data E
}
Constructors of a \data definition and fields of a \class or a \record definition are defined inside the module associated to the definition, but they are also visible outside this module. In particular, in the following example f1 and f2 are defined by identical expressions.
\data d
| a
| b d
\func f1 => b a
\func f2 => d.b a
Normally the members of a where block do not interact with the definition to which the block is attached. However, where blocks of \data and \class definitions may contain special instructions that do modify the type of parent definition (or e. g. introduce an automatic type coercion for it). Such instructions begin with the keyword \use and are discussed in greater detail in Coercion and Level.
Open commands
The contents of a given module can be added to the current scope by means of \open command (this is called ‘opening’ a module). The \open command affects all definitions in the current scope.
\func h1 => f
\module M \where {
\func f => 0
\func g => 1
}
\open M
\func h2 => g
The command \open M (def_1, … def_n) adds only definitions def_1, … def_n to the current scope. Other definitions must be refered to by their full names.
The command \open M \hiding (def_1, … def_n) adds all the definitions of M except for def_1, … def_n. These definitions still can be refered to by their full names.
The command \open M (def_1 \as def_1’, … def_n \as def_n’) adds definitions def_1, … def_n under the names def_1’, … def_n’, respectively.
The command \open M \using (def_1 \as def_1’, … def_n \as def_n’) can be used to add to the current scope all of the definitions of M while renaming some of them.
\module M \where {
\func f => 0
\func g => 1
\func h => 2
}
\module M1 \where {
\open M (f,g)
\func h1 => f
\func h2 => g
\func h3 => M.h -- we can refer to M.h only by its full name.
}
\module M2 \where {
\open M \hiding (f,g)
\func h1 => M.f -- we can refer to M.f and M.g only by their full names.
\func h2 => M.g
\func h3 => h
}
\module M3 \where {
\open M1 (h1 \as M1_h1, h2)
\open M2 \using (h2 \as M2_h2) \hiding (h3)
\func k1 => M1_h1 -- this refers to M1.h1
\func k2 => h1 -- this refers to M2.h1
\func k3 => h2 -- this refers to M1.h2
\func k4 => M2_h2 -- this refers to M2.h2
\func k5 => M1.h3 -- we can refer to M1.h3 only by its full name.
}
Note that if you open a module M inside a module M’ and then open M’ inside M’’, then definitions from M will not be visible in M’’. You need to explicitly open M inside M’’ to make them visible.
Import commands
If you have several files, you can use the \import command to make one of them visible in another. For example, suppose that we have files A.ard, B.ard, a directory Dir, and a file Dir/C.ard with the following content:
-- A.ard
\func a1 => 0
\func a2 => 0
\where \func a3 => 0
-- Dir/C.ard
\import A
\func c1 => a1
\func c2 => a2.a3
-- B.ard
\import Dir.C
\func b1 => c1
-- \func b2 => a1 -- definitions from file A are not visible
-- \func b3 => A.a1 -- you cannot refer to definitions from file A by their full names.
\func b4 => Dir.C.c2 -- you can refer to definitions from file Dir/C.ard by their full names.
The \import command also opens the content of the imported file. You can use the same syntax as for \open commands to control which definitions will be opened. If you want only to import a file and not to open any definitions, you can write \import X (). Then you can refer to definitions from the file X by their full names:
-- X.ard
\func f => 0
-- Y.ard
\import X()
\func f => X.f


--- layout: post title: "Uncurry isomorphisms" description: "Curried functions are isomorphic to tupled functions." date: 2018-02-05 7:54 UTC tags: [Software Design, Haskell, F#] --- {% include JB/setup %}
{{ page.description }}
This article is part of a series of articles about software design isomorphisms. Nota bene: it's not about Curry–Howard isomorphism. In order to prevent too much confusion, I chose the title Uncurry isomorphism over Curry isomorphism.
The Haskell base library includes two functions called curry
and uncurry
, and for anyone aware of them, it should be no surprise that they are each others' inverses. This is another important software design isomorphism, because in the previous article, you saw that all methods can be represented in tupled form. The current isomorphism then extends that result because tupled and curried forms are isomorphic.
While Haskell programmers are likely to be familiar with curry
and uncurry
, developers more familiar with other languages may not know them well. In this section follows an introduction in F#. Haskellers can skip it if they like.
In F#, you often have to interoperate with code written in C#, and as the previous article explained, all such methods look to F# like functions taking a single tuple as input. Sometimes, however, you'd wish they were curried.
This little function can help with that:
// ('a * 'b -> 'c) -> 'a -> 'b -> 'c let curry f x y = f (x, y)
You'll probably have to look at it for a while, and perhaps play with it, before it clicks, but it does this: it takes a function (f
) that takes a tuple ('a * 'b
) as input, and returns a new function that does the same, but instead takes the arguments in curried form: 'a -> 'b -> 'c
.
It can be useful in interoperability scenarios. Imagine, as a toy example, that you have to list the powers of two from 0 to 10. You can use Math.Pow, but since it was designed with C# in mind, its argument is a single tuple. curry
to the rescue:
> List.map (curry Math.Pow 2.) [0.0..10.0];; val it : float list = [1.0; 2.0; 4.0; 8.0; 16.0; 32.0; 64.0; 128.0; 256.0; 512.0; 1024.0]
While Math.Pow
has the type float * float -> float
, curry Math.Pow
turns it into a function with the type float -> float -> float
. Since that function is curried, it can be partially applied with the value 2.
, which returns a function of the type float -> float
. That's a function you can use with List.map
.
You'd hardly be surprised that you can also uncurry
a function:
// ('a -> 'b -> 'c) -> 'a * 'b -> 'c let uncurry f (x, y) = f x y
This function takes a curried function f
, and returns a new function that does the same, but instead takes a tuple as input.
Haskell comes with curry
and uncurry
as part of its standard library. It hardly comes as a surprise that they form an isomorphism. You can demonstrate this with some QuickCheck properties.
If you have a curried function, you should be able to first uncurry
it, then curry
that function, and that function should be the same as the original function. In order to demonstrate that, I chose the (<>)
operator from Data.Semigroup
. Recall that Haskell operators are curried functions. This property function demonstrates the round-trip property of uncurry
and curry
:
semigroup2RoundTrips :: (Semigroup a, Eq a) => a -> a -> Bool semigroup2RoundTrips x y = x <> y == curry (uncurry (<>)) x y
This property states that the result of combining two semigroup values is the same as first uncurrying (<>)
, and then 'recurry' it. It passes for various Semigroup
instances:
testProperty "All round-trips" (semigroup2RoundTrips :: All -> All -> Bool), testProperty "Any round-trips" (semigroup2RoundTrips :: Any -> Any -> Bool), testProperty "First round-trips" (semigroup2RoundTrips :: First Int -> First Int -> Bool), testProperty "Last round-trips" (semigroup2RoundTrips :: Last Int -> Last Int -> Bool), testProperty "Sum round-trips" (semigroup2RoundTrips :: Sum Int -> Sum Int -> Bool), testProperty "Product round-trips" (semigroup2RoundTrips :: Product Int -> Product Int -> Bool)
It's not a formal proof that all of these properties pass, but it does demonstrate the isomorphic nature of these two functions. In order to be truly isomorphic, however, you must also be able to start with a tupled function. In order to have a similar tupled function, I defined this:
t2sg :: Semigroup a => (a, a) -> a t2sg (x, y) = x <> y
The t2 in the name stands for tuple-2, and sg means semigroup. It really only exposes (<>)
in tupled form. With it, though, you can write another property that demonstrates that the mapping starting with a tupled form is also an isomorphism:
pairedRoundTrips :: (Semigroup a, Eq a) => a -> a -> Bool pairedRoundTrips x y = t2sg (x, y) == uncurry (curry t2sg) (x, y)
You can create properties for the same instances of Semigroup
as the above list for semigroup2RoundTrips
, and they all pass as well.
curry
and uncurry
only works for pairs (two-tuples) and functions that take exactly two curried arguments. What if you have a function that takes three curried arguments, or a function that takes a triplet (three-tuple) as an argument?
First of all, while they aren't built-in, you can easily define corresponding mappings for those as well:
curry3 :: ((a, b, c) -> d) -> a -> b -> c -> d curry3 f x y z = f (x, y, z) uncurry3 :: (a -> b -> c -> d) -> (a, b, c) -> d uncurry3 f (x, y, z) = f x y z
These form an isomorphism as well.
More generally, though, you can represent a triplet (a, b, c)
as a nested pair: (a, (b, c))
. These two representations are also isomorphic, as is (a, b, c, d)
with (a, (b, (c, d)))
. In other words, you can represent any n-tuple as a nested pair, and you already know that a function taking a pair as input is isomorphic to a curried function.
From abstract algebra, and particularly its application to a language like Haskell, we have mathematical abstractions over computation - semigroups, for example! In Haskell, these abstractions are often represented in curried form. If we wish to learn about such abstractions, and see if we can use them in object-oriented programming as well, we need to translate the curried representations into something more closely related to object-oriented programming, such as C# or Java.
The present article describes how functions in curried form are equivalent to functions that take a single tuple as argument, and in a previous article, you saw how such functions are isomorphic to C# or Java methods.

More transit woes loom
by The Canadian PressThe union representing almost 5,000 Metro Vancouver transit employees announces the next steps in its job action against Coast Mountain Bus Company today as drivers resume an overtime ban, potentially affecting many busy bus routes.
Unifor says it will move to the next phase of job action because Coast Mountain, which handles Metro Vancouver transit on behalf of TransLink, has failed to make any new offers and talks remain stalled.
Bus drivers, SeaBus operators and mechanics launched limited strike action Nov. 1 including an overtime ban by mechanics, and expanded the ban to add bus drivers when talks broke off last week.
SeaBus sailings have been affected since the start of the strike, although no cancellations are currently slated, and Coast Mountain is warning of bus disruptions today after the drivers' rotating ban affected about 10 per cent of routes on Friday and Monday.
Escalation in the strike comes as CUPE Local 7000, which represents SkyTrain workers on two rapid transit lines, says results of a strike vote are due Thursday, although a mediator remains involved in those talks and job action is not immediately expected.
The union says its 900 members are seeking better wages and working conditions and decided to hold the strike vote when the employer, B.C. Rapid Transit Company, rejected new bargaining dates.

Zoom Calls: Virtual Etiquette in a Transformative World
Note
: This article contains vocabulary that appeals to a wider audience.
What you’ll learn in this article
In this article, you will learn a few things that have helped me with best practices in virtual calls:
- How to setup your virtual calls
- General Zoom Etiquette
- General conversing notes
- How to exit a call
Motivation
During these unprecedented times, people around the world are going through major difficulties that either are pushing them into a lower in class, or is increasing the existing social status division. To help mitigate that in any way, I thought I’d offer my consultation on effectively transitioning into digital communication or learning.
2. Joining a Call
2.1 Pre-join
Getting ready for your zoom call? The following are good steps I take before joining a call:
- Wifi Connection
- Earphones/Headphones
- Backup earphones
- Position your camera properly
- Phone on “vibrate” mode, audio down
- If call is password protected, the password
- Join 2-3mins early, if an interview
- First timer? 5+mins
2.2 The Join
- When entering the call, ensure you are on mute
- Be mindful of background noise
- [Optional] Shy? Bad hair day? Disable Video
- However, if the meeting requires you have your video on, then do as such
- Mind your environment
- E.g. No random items or things to be seen are not in the background
3. What to Wear
3.1 General Advice
-
If you’re in an interview, I highly advise you wear clothes as if you’re going into an in-person interview.
-
If you care about letting your appearance “pop out” a bit, using a light can help your image. I heard about Ring lights; check it out!
-
Pretty much, if you know you’re attending a virtual event that requires a formality in-person, wear such clothes
3.2 The Specifics
- Tops
- If you’re in not in an interview, I advise on wearning a comfortable, but appropriate shirt.
- If you’re still working though, be sure to wear what is suitable for your team’s comfortability
- If you’re in not in an interview, I advise on wearning a comfortable, but appropriate shirt.
- Bottoms:
- If you’re cold, sweats will do. However, do know that when you stand up, you’ll like you got out of bed
- If you want to be comfortable, I recommend wearing shorts. Personally, I wear Uniqlo Easy Shorts
4. Mind the….
4.1 Mind the Speaker
(i.e. Respekt the person talking)
- Address Internet Disruptions
- If addressed, first do it via Chat. After, try by turning on audio again
- Try to avoid talking at the same time as other participants
- If an interruption occurs, take a few humbling seconds to let the other person speak
4.2 Mind the Attendees
- Limit distractions
- Be aware you are on camera
- Don’t be me, easily getting distracted by Tweets (maybe youre case, TicTok?)
- Take your time sharing your screen.
- You don’t want to share a screen of your favorite music Playlist
Some may ask…
It’s just about respecting others, I suppose. I can write some long paragraph about why, but I’ll say this, especially during these times
:
“Treat people with respect, if you want that same respect back”
5. Ending the Call
5.1 Cues
Ending a call can be tricky sometimes. In a social context, there are small “cues” that show when a conversation ending
I’m more of the receiving end of those haha
However, virtual calls are quite different in identifying when a call should end. The following are some things I noticed that help me out:
-
Near the end of the discussion, a person is quickly eyeing their time
-
There is nothing to further discuss, aroudn 2/3’s of the call’s expected timeframe
5.2 Saying Goodbye
Here are the top ranked ways I look to say goodbye
- Wave goodbye & smile [Optional]
- Just being friendly :)
- Recently, I found out people do “peace sign” goodbyes
- Saying goodbyes, meanwhile you’re hovering the exit button
- This helps mitigate awkward seconds of ending a call

Bright Inventions was founded in 2012 by two guys bored with corporate inertia and lack of fun. We knew that work could be fun, refreshing and approached with happy attitude.
Now in 2016 there’s 9 of us and we’re only starting.
As a company founded by Software Developers we know that we need to stay on top of the bleeding-edge technologies and keep progressing profesionally to be even more productive and helpful towards our customers.
Michał Łukasiewicz is an idea guy. Starts 5 new things weekly. Workaholic. When he is on vacation, he works only part-time so that his employees never need to work overtime.
Daniel Makurat always thinks differently. His ideas often sound odd at first, but turn out to be really Bright in the end. Works mostly in iOS, but Ruby scars are still visible.
Piotr Mionskowski is a real Full Stack Developer, probably the only one who touched every possible technology and the default go-to person in case of problems. TDD fan that always asks ’Why?’.
Mateusz Klimczak - Trello guy, has everything planned ahead. Does the job of ten corporate line managers at once while running 3 iOS projects in the meantime.
Mateusz Klimek is the Android guy who leaves us soon to join his girlfriend abroad. This must be stronger than his Java affair.
Adam Bar is the web enthusiast. He is trying to convince everyone we wouldn't need mobile apps some day. A fan of order and structure.
Eliasz Sawicki is a world-class conference speaker to be. Eager to experiment with the new stuff. Mostly working in iOS, but not afraid of JavaScript fatigue.
Kamil Wysocki works in iOS. Has highly developed usability intuition. He is always trying to cover all cases while creating new stuff.
Agnieszka Olszewska joined the team to do big things in Big Data. Privately keen on big mountains. Always smiling.

2C-T-4 |
(capsule) |
8:30 am - planning to take 30mg 2C-T-4 HCl orally. is my first time with this substance. i am interested to see what my experience will be like.
- expectations: this is supposed to be a long-lasting substance (12-16 hours) The come-up period is long, occurring over about 3 hours. I am assuming that the high dose may extend the length of effects to perhaps 20 hours. the substance is not reported to have a strong body load compared to 2C-T-7 or 2C-T-2, however there were a few reports of brief nausea or stomach discomfort and muscle tension. Many of the reports described a psychedelic state 'different' than that of 2C-T-7 or 2C-T-2. Some suggested that the visual component was less prominent.
reason for higher than usual dose: experiences with 2C-T-7 were most rewarding for me at 40 - 50 mg oral dosages (compared to PiHKAL dosage range of 10 - 30 mg)... by analogy I choose to take 30 mg compared to PiHKAL dosage range of 8 - 20 mg.
9 am - ingest 30 mg of 2C-T-4 HCl in a gel cap. gel cap ingested without any difficulty, washed down with a swig of iced root beer. NPR is playing in the background.
9:30 am - not feeling much of anything yet, perhaps a mild sensation of looseness or indifference... however, computer screen seems to have greater than usual brightness contrast. what this will develop into, let's see...
10:00 am - Still not feeling much... there are some effects, but they are very indistinct and mild. turn off NPR and put on the movie 'eXistenZ'
10:30 am - effects becoming noticeable. there is some visual alteration but it is different than that of other psychedelics -- no breathing or patterning, just a change in the quality of light and depth. Things seem slightly tinged green-blue. Lots of paraesthesia, some chilly feelings, body stretches. A slight queasiness and a couple episodes of shivers, shakes and retching, but these are perceived as minor & not really distracting or unpleasant. Overall feeling is calm. So far this is feeling pretty good, and different than other psychedelics. There does not seem to be a stimulant aspect; I feel as though i could even go to sleep if desired. It is interesting that people report not being able to sleep at the tail end of the experience. There is no great enhancement of the thought process. Physically, this does not feel like sensitization, more like 'flowing'.
11:30 am - effects are strong and still gaining in strength. there are still no traditional psychedelic visuals, although the visual field is altered and enhanced in a shimmering way. CEVs are present but modest. Body feel is pleasant and relaxed... good tone, yawning, a unique buzzfeel, limited bandwidth. Sense of queasiness has dissipated, was never significant. emotional feeling is calm and good natured. movie eXistenZ has finished. enhanced appreciation for conceptual play in the movie, picked up on some new insinuations. There was a lucidity of vision; faces of characters stood out, facial expressions were experienced with great clarity, body language and vocal inflection were perceived as an open, literal, intelligible information channel.
There does not seem to be a sense of intense sensory or emotional drama with this compound, especially compared to some of the tryptamines. Also it does not seem possible to 'curl' the experience into a greater degree of intensity by interior concentration (in contrast to 2C-I) Yet the sense of alteration is very distinct and strong: a physical and mental feeling of being 'spaced out', yet still focused on the immediate surroundings. Thinking is clear, somewhat dispassionate. putting NPR back on and lying down.
12:00 pm -3:00 pm - effects at a plateau for the last 3 hours. +++, intense (would not want to be in public) but definitely manageable (no trouble typing). feeling is comfortable and 'unique'. there are no spectacular fireworks on the upside (no explosion of thoughts, insights, visions or perceptions), and no dark corners or body load on the downside. Absolutely no muscle tension. Tactile is somewhat velvety, but totally non-erotic. this is not an escapist material; presence is firmly grounded in the surroundings. 30 mg seems to be a good level of 2C-T-4 for me. Ate some celery… It was considered that 2C-T-4 is the 'celery' psychedelic.
3:30 pm - effects are diminishing in intensity. at a ++. it seems that there is indeed a lot of variability between individuals in the dosage and duration of this compound
5:30 pm - at a pleasant + and a half,
10:30 pm - at a bland +.
3:00 am - threshold effects still present. no headache, no muscle tension, no peripheral stimulation. on the other hand, no meaningful effects, and sleepy but somehow no sleep possible. the first 8 hours of 2C-T-4 are good, the last 8 hours I could do without. Feel like taking a shower.
Overall, much different than 2C-T-7 or any of the other psychedelics I have tried. Pleasant, unique, but unspectacular.

SoXI(1) Sound eXchange SoXI(1) NAME SoXI - Sound eXchange Information, display sound file metadata SYNOPSIS soxi [-V[level]] [-T] [-t|-r|-c|-s|-d|-D|-b|-B|-e|-a] infile1 ... DESCRIPTION Displays information from the header of a given audio file or files. Supported audio file types are listed and described in soxformat(7). Note however, that soxi is intended for use only with audio files with a self-describing header. By default, as much information as is available is shown. An option may be given to select just a single piece of information (perhaps for use in a script or batch-file). OPTIONS -V Set verbosity. See sox(1) for details. -T Used with multiple files; changes the behaviour of -s, -d and -D to display the total across all given files. Note that when used with -s with files with different sampling rates, this is of ques‐ tionable value. -t Show detected file-type. -r Show sample-rate. -c Show number of channels. -s Show number of samples (0 if unavailable). -d Show duration in hours, minutes and seconds (0 if unavailable). Equivalent to number of samples divided by the sample-rate. -D Show duration in seconds (0 if unavailable). -b Show number of bits per sample. -B Show the bitrate averaged over the whole file (0 if unavailable). -e Show the name of the audio encoding. -a Show file comments (annotations) if available.

We want to roll a 4-sided dice and a 6-sided dice. Given that the 4-sided dice has a result of $x1_str (but not $x2_str), find the conditional probability that the sum of the two dice is $x3 or larger.
| Question | Answer |
|---|---|
| What is the total number of outcomes for rolling the two dice when all outcomes are pssible for each dice | |
| What is the number of outcomes for rolling two dice if the 4-sided dice has a result of $x1_str (but not $x2_str) | |
| For the case when 4-sided dice has restrictions, how many of outcomes sum equal to or greater than $x3 | |
| Given that the 4-sided dice has a result of $x1_str (but not $x2_str), find the conditional probability that the sum of the two dice is $x3 or larger |
Explanation:
Here are all the possible outcomes of this experiment:
$all_pairs
You can divide the number of outcomes matching the condition, sum of the two dice is $x3 or larger , by the total number of outcomes


The measured accidental coincidence rate is
and the accidental coincidence rate calculated from the singles rate is [20], where
= coincidence gate length,
therefore the ratio
should be unity within statistical errors. Set
The accidentals/singles test passes if
where is the accidentals/singles precision limit in percent (default = 0.1 %) or if
where is the accidentals/singles outlier limit in standard deviations (default = 3) and is an empirical estimate of the standard deviation of .
The accidentals/singles test is not done if
where is the accidentals/singles test rate limit (default: 1000 counts/s). The test is also not done for background measurements.
