leaks

I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

Hello guys I am an iOS Developer building a Flutter app and I was wondering if the concept of memory cycle (retain cycle exists here). "Strong reference cycles negatively impact your application's performance. They lead to memory leaks and unexpected behaviour that is often hard to debug". By replacing a strong reference with a weak reference, the relationship between the objects remains intact and the strong reference cycle is broken. So in flutter there is no concept about weak reference. So how can you solve this problem, or there is no need to do that? Below I will leave an example.

I searched a lot how to authenticate/authorize Google's client libraries and it seems no one agrees how to do it.

Some people states that I should create a service account, create a key out from it and give that key to each developer that wants to act as this service account. I hate this solution because it leaks the identity of the service account to multiple person.

Others mentioned that you simply log in with the Cloud SDK and ADC (Application Default Credentials) by doing:

Haskell provides a convenient function forever that repeats a monadic effect indefinitely. It can be defined as follows:

The following code compiles in both GNU gfortran and Intel ifort. But only the gfortran compiled version will run successfully.

I'd like to be able to use GitHub Actions to be able to deploy resources with AWS, but without using a hard-coded user.

I know that it's possible to create an IAM user with a fixed credential, and that can be exported to GitHub Secrets, but this means if the key ever leaks I have a large problem on my hands, and rotating such keys are challenging if forgotten.

Is there any way that I can enable a password-less authentication flow for deploying code to AWS?

I have a program that exhibits the behavior of a memory leak. It gradually takes up all of the systems memory until it fills all swap space and then the operating system kills it. This happens once every several days.

I have extensively profiled the heap in a manner of ways (-hy, -hm, -hc) and tried limiting heap size (-M128M) tweaked the number of generations (-G1) but no matter what I do the heap size appears constant-ish and low always (measured in kB not MB or GB). Yet when I observe the program in htop, its resident memory steadily climbs.

What this indicates to me is that the memory leak is coming from somewhere besides the GHC heap. My program makes use of dependencies, specifically Haskell's yaml library which wraps the C library libyaml, it is possible that the leak is in the number of foreign pointers it has to objects allocated by libyaml.

My question is threefold:

1. What places besides the GHC heap can memory leak from in a Haskell program?
2. What tools can I use to track these down?
3. What changes to my source code need to be made to avoid these types of leaks, as they seem to differ from the more commonly experienced space leaks in Haskell?

I have the following code:

It has been discussed many times on Stackoverflow that by default WebRTC technology leaks your real IP even if your using a proxy to browse the web. What I haven't seen discussed is whether this requires the end user to click a button to enable this kind of leak or whether the leak occurs regardless of any action taken by the user.

For example, when you go to Express VPN they require you press a button to test for WebRTC leak. My question is - is this done for privacy reasons or somehow the button activates WebRTC tech so it can leak your IP?

In other words, assuming you never need to use WebRTC tech (just browser a blog or eCommerce shop) and all you do is click a few links - can a website still detect your real IP through WebRTC?

Thanks
