QuickBlox Multiparty Video Conferencing SDK for Javascript
The QuickBlox Multiparty Video Conferencing SDK provides a JavaScript library to access the QuickBlox Multiparty Video Conferencing API.
Version
0.2.0
Dependencies for browser
For the library to work, you need to include adapter.js in your html before quickblox-multiparty-video-conferencing-client.min.js
, like so:
<script src="adapter.js"></script>
<script src="quickblox-multiparty-video-conferencing-client.min.js"></script>
Integration
Initialize framework
var client;
$(function() {
var config = {"server": "wss://...:8989"};
client = new QBVideoConferencingClient(config);
});
Possible configs:
'server' - Janus server endpoint
'debug' - Enable internal debug logs: true/false.
'iceServers' - a list of ICE servers
'video.quality' - Video quality. Possible values: 'lowres' (320x240), 'hires' (640x480). Default is 'hires'.
'video.frameRate' - Video framerate: Range: 15-29. Default is 29.
Create session
Once the library has been initialized, you can start creating session. Normally, each browser tab will need a single session with the server:
client.createSession({
success: function() {
},
error: function(error) {
},
destroyed: function() {
}
});
Once created, you can interact with a Video Conferencing API in several different ways.
Attach Video Conferencing plugin
Next, the most important step is obviously attach Video Conferencing plugin, as it's what will allow you to exploit the features of a plugin to manipulate the media sent and/or received by a PeerConnection in your web page. This method will create a plugin handle internally, for which you can configure callbacks.
You also have to attach plugin to each remote user.
var isRemote = ...;
var userId = ...;
client.attachVideoConferencingPlugin(isRemote, userId, {
success: function() {
},
error: function(error) {
},
consentDialog: function(on) {
},
webrtcState: function(on){
},
mediaState: function(medium, on) {
},
iceState: function(iceConnectionState){
},
slowLink: function(uplink, nacks) {
},
oncleanup: function(){
}
});
Join video room
To jump into video chat with users you should join it:
var chatDialogId = "...";
var currentUserId = ...;
var isAudioCallOnly = false;
client.join(chatDialogId, currentUserId, isAudioCallOnly, {
success: function(){
},
error: function(error){
}
});
To check curently joined video room use the following property:
client.currentDialogId
List online participants
To list online users in a video chat:
client.listOnlineParticipants(chatDialogId, {
success: function(participants){
},
error: function(error){
}
});
Callbacks
There are 4 callbacks you can listen for. You can use method 'on' to add them:
client.on("participantjoined", function(userId, userDisplayName){
}
client.on("participantleft", function(userId, userDisplayName){
}
client.on("localstream", function(stream){
QBVideoConferencingClient.attachMediaStream($('#myvideo').get(0), stream);
}
client.on("remotestream", function(stream, userId){
// do not add stream if it's already here
if(feedViewIsAlreadyAdded(userId)){
return;
}
addFeedView(userId, false);
QBVideoConferencingClient.attachMediaStream($('#remotevideo'+userId).get(0), stream);
}
To remove all listeners the following code can be applied:
client.removeAllListeners("participantjoined");
client.removeAllListeners("participantleft");
client.removeAllListeners("localstream");
client.removeAllListeners("remotestream");
Mute audio
You can mute/unmute your own audio:
var muted = client.toggleAudioMute();
console.info("Now audio is muted=" + muted);
Mute remote user's audio
You also can mute/unmute remote user's audio:
var muted = client.toggleRemoteAudioMute(userId);
console.info("Now remote audio is muted=" + muted);
Mute video
You can mute/unmute your own video:
var muted = client.toggleVideoMute();
console.info("Now video is muted=" + muted);
Mute remote user's video
You also can mute/unmute remote user's video:
var muted = client.toggleRemoteVideoMute(userId);
console.info("Now remote video is muted=" + muted);
Display bitrate
There is a way to show video bitrate of remote user. The following string will be shown in element - '180 kbits/sec' and will be refreshed each 1 second.
var userId = ...;
client.showBitrate(userId, $('#curbitrate'+userId));
var userId = ...;
client.hideBitrate(userId, $('#curbitrate'+userId));
List video input devices (cameras)
QBVideoConferencingClient.listVideoinputDevices(function(videoinputDevices){
for (var i=0; i!== videoinputDevices.length; ++i) {
var deviceInfo = videoinputDevices[i];
//deviceInfo.label
//deviceInfo.deviceId
}
});
Switch video input device (camera)
In order to switch video camera you have to obtain a list of currently plugged video cameras with QBVideoConferencingClient.listVideoinputDevices method.
var deviceId = "...";
client.switchVideoinput(mediaDeviceId, {
error: function(error) {
},
success: function() {
}
});
Leave video room
To leave current joined video room:
client.leave({
success: function(){
},
error: function(error){
}
});
Detach Video Conferencing plugin
When job is done you should detach Video Conferencing plugin - the following method detaches from the plugin and destroys the handle, tearing down the related PeerConnection if it exists:
client.detachVideoConferencingPlugin({
success: function() {
},
error: function(error) {
}
});
Destroy session
And the final step to fully close/cleanup everything is to destroy session:
client.destroySession({
success: function(){
},
error: function(error){
}
});

Highland Park 12 - Part 1
Whisky Bob starting things off here with a week of daily Highland Park 12. Highland Park is the northernmost Scottish Distillery on the Orkney archipelago. Their whiskys are renowned for their complex flavor profiles that touch on all the Scottish regions.  I picked up an older non-Viking 750 mL bottle of their standard 12 year release in suburban Boston for $43.
Drinking neat in a Glencairn. Color: medium deep amber. Nose: sweetness. Lots of sweetness. Surgary. Some sour notes. Alcohol burn when I stick my nose way into the glass (note - duh!)
There’s a decent amount of smokiness in the mough. The finish is dry on the tongue. The smokiness lingers in my mouth, kicks off its boots and hangs out awhile. It’s not as overpowering as an Islay and is altogether different in character. There’s a nice sweetness here, too. Floral notes - this might be the “heather” from the tasting notes but I can’t relate to that term. Breathing in air tickles my mouth and brings a numbing sensation.  I close my mouth and the smokey flavors take over.
I let it sit awhile and come back. More brown sugar on the nose. More honey flavoring than before. There’s still that lasting smoke and dryness on the finish. I take the last sip straight down the throat over my tongue and get a lot more smoke. This is complex stuff yet the flavors appear at random and seem very disjointed. I look forward to spending the week with this fella.

KICKING AND SCREAMING A film review by James Berardinelli Copyright 1995 James Berardinelli
RATING (0 TO 10): 6.4
United States, 1995 U.S. Availability: 11/95 (limited) Running Length: 1:34 MPAA Classification: R (Mature themes, nudity, sexual situations, profanity) Theatrical Aspect Ratio: 1.85:1
Cast: Josh Hamilton, Olivia D'Abo, Chris Eigeman, Parker Posey, Jason Wiles, Carlos Jacott, Carla Buono, Eric Stoltz, Elliot Gould Director: Noah Baumbach Producer: Joel Castleberg Screenplay: Noah Baumbach based on a story by Noah Baumbach and Oliver Berkman Cinematography: Steven Bernstein Music: Phil Marshall U.S. Distributor: Trimark Pictures
If we're to believe the movies, members of the so-called Generation X are hopelessly caught in the grip of ennui, struggling (and mostly failing) to make sense out of life and the world in general. We've seen this story so many times that it's starting to wear thin. In many ways, KICKING AND SCREAMING is mildly enjoyable, but all it really does is go over old ground with new characters.
Much of KICKING AND SCREAMING's appeal results from its cast. Josh Hamilton (WITH HONORS) is the weakest of the performers, giving a somewhat bland portrayal as Grover, a 22-year old would-be author with writer's block. Much better is Olivia D'Abo (THE LAST GOOD TIME, GREEDY) as Jane, his girlfriend, who decides to move to Prague after graduating. Chris Eigeman essays Max, a character with the same sort of acerbic wit as the ultra-patriotic American he brought to life in BARCELONA. Jason Wiles, Carlos Jacott, and Parker Posey are effective as Grover and Max's friends. And what would any Gen X picture be without the presence of the ubiquitous Eric Stoltz?
The basic premise of KICKING AND SCREAMING is to follow a small group of college graduates as they are reluctantly forced to face "reality"--moving away from campus, forming new relationships, and getting jobs. As it turns out, none of the characters are able to make a clean break. Grover and Max still hang out around their alma mater, Jane runs away to another country, Otis (Jacott) goes to grad school, Skippy (Wiles) audits a few classes, and Chet (Stoltz), the career student, returns semester after semester.
The characters are all pretty likable, and it's not too hard to sympathize with their situation--at least until their social paralysis becomes irritating. But KICKING AND SCREAMING is essentially a film of moments. Much of the dialogue is crisp, and there are several individual scenes that work to near-perfection (most notably the flashbacks that detail the building of Grover and Jane's relationship), but the connecting material is weak. Above all, the movie comes to a conclusion without a sense of closure.
KICKING AND SCREAMING is often witty, occasionally hilarious, and ultimately bittersweet. But, in the final analysis, there's not much here that's original or insightful. This is essentially the story of a group of post-college slackers wrestling with life's many, varied tribulations--not exactly virgin ground for '90s film makers. And, in this case, what's on screen is just a little too familiar to be worth lauding.

eXtreme Programmer
In the context of ever-increasing expectations, combined with the environment of ever-growing number of technologies and frameworks, it is hard not to fall into the trap of building for the sake of building. Teams spend precious man-months setting up custom instances of Wordpress, Magento, .NET MVC, React, you name it. Doesn’t it sometimes feel that we’re spending increasingly more time building the same things (CMS, CRUD, E-Com) and less time building something that actually matters?
This talk will explore fresh “new” world of Serverless and the surrounding ecosystem. And in exploring this, we would try to identify better ways of serving ever-increasing business needs without spending exponentially more time solving already solved problems.
You might not need a server, CI pipeline, CMS, E-commerce or general framework. Because if someone else solves that for you, you will have all the time in the world to do something that deeply matters for your stakeholders.
There are many commonly accepted truths in modern software development. Most of them are born from years of hitting hundreds of walls with thousands of heads. Some good examples of such axioms are:
In this workshop we will experiment with Elixir - a fresh new programming language built on the shoulders of giants that are Erlang and OTP. During this experimentation we will explore how Elixir and OTP directly challenge the above “truths”. It turns out, web can be stateful with cheap long-running processes and web sockets. Functional programming can be fun without many semantic overheads. Parallelisation can be made easy with actor model embedded into the language kernel. Scaling can be straight-forward if it is built into underlying language infrastructure. And you don’t need to write a single line of JavaScript if all you need is realtime dashboard or chat.
This is not a training for beginner developers, nor is it a certification course for experienced Beam/Erlang/OTP/Elixir engineers. This a one-day roller-coaster ride of exploring exciting and interesting toys Erlang ecosystem provides. We would do a very shallow dive over many aspects of Elixir, but would rarely dig deep below the surface. The purpose of this day is to get you excited about Elixir and OTP, not to make you an expert in them.
This workshop, aimed at experienced non-Erlang/Elixir engineers, is designed to give you an introductory ride across the Elixir ecosystem and provide you with tools to get started with it, coupled with the knowledge of when such a move would be appropriate.
Bring your laptop with Linux/MacOS as a main OS or within your VM of choice.
