geolocation – ideas required: getting realtime location of multiple user on android

my app will be used by multiple users, where app will track users location in real time.

I want to map everyone’s location on single map to show who else is nearby. Currently i’m thinking of getting users location and saving in DB and updating every minute or so

If there are any other ideas or if there are any readymade libraries available to achieve this would be great. thanks in advance.

r – Seeking ideas for better efficiently deleting an element in a vector

While experimenting with some algorithm I decided to simulate it in R.
I have a number of chronological elements in an array, and I want to prevent unlimited growth as new samples are added.
So I decided to start removing older samples with a somewhat higher probability than more recent samples.

OK, enough background, here’s the function that does the “thinning”:

f <- function(v) {
    l <- length(v)
    p  <-  l
    nv <- c(NULL)
    for (i in 1:l) {
        print(c(nv,"|",v(i:l)))
        if (trunc(runif(1, 0, p)) == 0) {
            nv <- c(nv, v(1:l > i))
            break
        }
        if (p > 1)
            --p
        nv <- c(nv, v(i))
    }
    v <- nv
}

Initially I had the line nv <- c(nv, v(i +1:l)), but that didn’t work, so I changed it. But I feel this algorithm is highly inefficient for large vectors.

To help understanding what f does, there are some simple test outputs (remove at most one element (also preferably at least one) from the vector C(1,2,3) (v <- f(v) is to allow multiple reductions):

> v<-c(1,2,3)
> print(v <- f(v))
(1) "|" "1" "2" "3"
(1) 2 3
> v<-c(1,2,3)
> print(v <- f(v))
(1) "|" "1" "2" "3"
(1) 2 3
> v<-c(1,2,3)
> print(v <- f(v))
(1) "|" "1" "2" "3"
(1) "1" "|" "2" "3"
(1) "1" "2" "|" "3"
(1) 1 2 3
> v<-c(1,2,3)
> print(v <- f(v))
(1) "|" "1" "2" "3"
(1) "1" "|" "2" "3"
(1) "1" "2" "|" "3"
(1) 1 2

Ideally I would compute the index of the element to drop, and then drop it.
In a functional language like R there does not seem to exist a way to avoid copying all but one elements, right?

❓ASK – Passive Earning Ideas or Programs | Proxies-free

Hi guys, let’s brainstorm and share ideas as to how to make 50 cents to $1 per day passively. I am with few programs like Microworkers, Ysense, Serpclix, 5 different PTC sites and make $30+. It might be a small amount but helps me pay my bill.

Please don’t suggest earning through website, blog, youtube channel because it might take a while to set up those income streams. I am looking for something immediate.

I am looking for ways or some legitimate programs online which would help us earn passively. Looking forward to your suggestions.

Ideas for monetizing online content

Hey there,
I was working really hard last year creating content. Mostly for my online-course.
It’s quite a huge course and i have lots and lots of text based content with spezifically designed graphics.- Jsut to give you guys a picture.
Some would say it’s foolish to make content without even rpooving it’s working, but i’m pretty certain it will, cause the idea works in other languages as well.

So i have tones of content and im wondering have i can monetize this content, beside using it in the course.
I thought about making a blog with it, but displaying banner ads, isn’t really profitable – do you know about more profitable methods?
-Making a Blog will certainly be a good lead-magnet.

I created tons of graphics, whoch im sure others can use… so maybe starting an online shop with those designs.

But i was hoping, maybe you guys have more knowlegde/ ideas or expieriences on how to monetize text based content.

Looking forward to your suggestions¨
