video – Is it possible to create a self-managed call application that does not take the audio focus?

I'm building a video chat app. The video chat SDK that I use (OpenTok) mutes when it loses the audio focus. I implemented a self-managed call application using ConnectionService to integrate with the telecommunication system. The problem is that the "call" that I create with the help of ConnectionService requires the audio focus, which cuts all the sounds in my video chat.

Is it possible to create an incoming call without to remove the audio focus of my application?

php – large website the best way to create a multi-language?

I work in a final academic project, such as an admin panel with huge displays and processes, and one requirement is the need to support multiple languages. Spanish English.

The project is based on:

and the web server is LAMP, do not use the php framework, use pure php, html, javascript, jquery, mysql.

but I think this website is too big to use the normal way of translations, any suggestion ??

I am aware that the question is subjective but there are so many options that when I go to see it, it remains for simple things and not for an administrative system, the other disadvantage is that the screens viewed are managed by ajax, they are supposed to be translated from the server (executed by php).

How to create an awesome TopGoldForum profile [TUTORIAL] – Newbies Lounge

Hello TGF members,

In this tutorial, I will show you how to get the most out of your TopGoldForum profile. You will be able to get more views of your posts, links, friends on social networks and be considered an expert in your niche.

Step 1. Add a profile picture

You must add an avatar or a profile picture and a cover photo of you and / or your company.

Access your profile by clicking on your username in the upper left corner, and when you tap your profile photo, a small image icon appears that you must click to add or edit.


Step 2. Add a cover photo

By adding a cover photo, you further personalize your account, which puts it out of the crowd.

Click the Cover Photo button, and then click Upload a photo. Select a suitable image (no nudity, abominable or hate please) and download it.


After that, you can drag it and position it as you wish. When you are satisfied with the result, simply click Save Position or Cancel if you want to start the process again.


Step 3. Fill in your social media accounts

By adding your social media accounts, you prove to the community that you are a real person and that you are serious about what you are doing.

Fill in all the details you are sure to share. When you're done, just click Save and you're done.


Step 5. Define a signature

The installation of a signature has many advantages. You get free backlinks every time you post something new and it's free advertising for your business.

Click your user name, and then access the account settings.


In the settings pane, navigate to the Signature tab.


With a standard account, you will be able to add up to 3 lines of text and 3 links. If you want to add banners and images, you need to buy a PREMIUM subscription.

physics – Create water in 3D Unity

I want to implement 3D water in my game similar to this 2D plugin.

I know that generally water is implemented using plane deformation. I can not use this approach because I want to implement realistic simulation of water similar to the 2D plugin above. I've tried to implement the water using metaballs but the performance is mediocre because I need thousands of metaballs.

I'm looking for suggestions on possible approaches using 3D water that can be implemented. Also, how fluid in this plugin is implemented?

r – How to select an object from the results of the localKcross function and create its envelope

I have two types of points (marks = 1 or 2) and I want to use the spatstat package of R to do a cross-locale analysis. The result of the function is drawn with several curves (each representing a point marked 1) .How can I use a loop? to choose one and make an envelope for each size?

I tried to write code, but the results were not satisfactory.


# Load points
points <- read.csv("E:/test_1.csv",sep = ",", header = TRUE, fileEncoding = "utf-8")

#Ripley k
localk <- function(x,y,codes,place) {
  p <- ppp(x, y, c(4000, 6000), c(-4500, -3000),marks = factor(codes))
  #lks <- localKcross(p,i="1",j="2",rmax = 100,correction='Ripley')

  kmult <- envelope(p, fun=localKcross, nsim=10, i="1", j="2",r=s,correction='Ripley', simulate=NULL)


  # setwd("E://kpic")
  # for(i in 1:900){
  #   idx = sprintf("%03d", i)
  #   pic <- paste("iso",idx," ~ r", sep = "")
  #   picname <- paste("iso",idx," ~ r",".png", sep = "")
  #   png(file=picname, bg="transparent")
  #   plot(lk,pic)
  #I don't know how to select one carve to do envelope
  #   kmult <- envelope(p, fun=localKcross, nsim=100, i="1", j="2",correction='Ripley', simulate=expression(rlabel(p)))
  #   plot(kmult)
  # }
res <- localk(points$X, points$Y,points$type,points$name)  

I'm waiting for every marked point 1 to make a Ripley curve and its envelope and save it in the image.
