I have been slowly building an online community for professionals in the Creative Arts. Recently I have been racking my brain with ways to promote the group through social media. I have tried a few things such as Reddit, Discord List Sites (garbage results), and now I have social media accounts set up across Twitter, Facebook, and Instagram.
I was curious to know if there are any other people here who have grown Discord Servers and know how to effectively market a group that is not for…
Social Networks for Promoting a Discord Server?
I am a contractor who does development for more than one client. Let’s call them Client A, Client B, and Client X.
I use my own laptop for all 3 clients.
Throughout the day, I have to work on and respond to emails and instant messages about projects for all 3 clients.
In order to work on Client X’s project, I must be connected to their VPN.
Client X performs SSL deep inspection on the traffic on their network. (I get errors from sites/apps that enforce key pinning)
I’m worried that information about Client A and Client B, (not to mention my own sensitive information) might be exposed to Client X. How can I prevent this, but still maintain my ability to communicate with A and B while working on X’s network?
I’ve tried giving each client its own VM on my machine, but the hefty resource requirements of the software I have to use (IDE) makes this prohibitively slow, to say nothing of the licensing difficulties.
In a noiseless channel can frames in the 2 layer of OSI model(Data link layer) reach to the destination out of order?

This article says the following:
Deciding between the sigmoid or tanh will depend on your requirement of gradient strength.
I have seen (so far in my learning) 7 activation functions/curves. Each one seems to be building on the last. But then like the quote above, I have read in many places essentially that "based on your requirements, select your activation function and tune it to your specific use case".
This doesn’t seem scalable. From an engineering perspective, a human has to come in and tinker around with each neural network to find the right or optimal activation function, which seems like it would take a lot of time and effort. I’ve seen papers which seem to describe people working on automatically finding the "best" activation function for a particular data set too. From an abstraction standpoint, it’s like writing code to handle each user individually on a website, independently of the others, rather than just writing one user authentication system that works for everyone (as an analogy).
What all these are papers/articles are missing is an explanation of why. Why can’t you just have one activation function that works in all cases optimally? This would make it so engineers don’t have to tinker with each new dataset and neural network, they just create one generalized neural network and it works well for all the common tasks today’s and tomorrow’s neural networks are applied to. If someone finds a more optimal one, then that would be beneficial, but until the next optimal one is found, why can’t you just use one neural network activation function for all situations? I am missing this key piece of information from my current readings.
What are some examples of why it’s not possible to have a keystone activation function?

I can see 1 of my 2 wifi networks. The 2nd wifi network doesnt show in my wifi pick list. One hidden network has a very strong signal, which leads me to beliwvw that it is my 2nd wifi network. I enter the SSID and the network security key (network password). It then says "do you want to allow your octo be discoverable by other pc’s and devices on this network". I hit Yes, and it says "Cant connect to this network".
I’m considering developing a simple WiFi scanner and logging App that can run as a service 24 hours a day for months passively collecting changes in the surrounding wireless environment with the following features:
- Log changes to BSSDs, ESSDs SSIDs, signal strength, number of clients, etc.
- Displaying everything on a simple dashboard;
- Notifications of new access points setup in the surrounding area;
- Notifications of new WiFi clients;
- Notifications of SSID changes;
- Possibly capture handshakes (though that’s not a primary objective);
- Run on a low cost platform such as a Raspberry Pi with a simple
apt-get install to get it started.
I’m very well aware that other solutions exit such as Kismet Logging but I don’t want invest too much time recreating a solution that already exists. Is there something that already does all of this, or a combination of tools I can try? E.g. Kismet & Kibana in a Docker image?
I use the client of a reputed paid VPN company. With each server location I connect to, the log tells me I am instead connecting to networks completely unrelated to the company and the country of the VPN location. But when I check my external IP address, my expected VPN location is returned. So it appears that my traffic is being routed (and logged?) through these strange networks, yet when I try to block them in the firewall, it still connects successfully, making me wonder if I am not connecting to these networks after all or if the firewall is unable to block the connections. Even if no shady routing (MitM) is actually taking place, the question remains: why are those IP addresses showing up in my logs? The signatures of both the VPN client and OpenVPN are valid.
I contacted support, and although they expressed concern, I couldn’t get any explanation in 30 minutes of chatting.
Here’s a redacted transcript of a log. Is there a possibility that my traffic isn’t actually being routed through those networks?

all community detection algorithms in major python packages are using only edges & edge weights. Is there any algorithm that uses multiple attributes of nodes to detect communities?
For ex, in social network, while edges imply relationships, nodes have attributes like age, gender, & interest. Given that FB does have predictions and suggestions, I suspect there are algorithms that use multiple factors to find communities.
It’s been a few years since I’ve played around with this so I’m not sure if times have changed.
When using AR7921 chipset (Alfa AWUS036NHA) on Ubuntu 20.04 I can see many networks using the following commands
airodump-ng start wlx00c0ca84d0f8 airodump-ng mon0
I’ve noticed all the VMxxxxx networks have a very low beacon count, perhaps 1 every 20 seconds (compared to e.g BT Broadband APs which seem to have a “normal” beacon count of several per second. The VMxxxx networks are Virgin Media home broadband networks- including the connection I’m legitimately using that is 6 feet away from me.
The rest of the networks have normal looking beacon counts. Has something changed/new technology in place that reduces the beacon count over the past few years or is the issue something else?
I can use the following command for half an hour on my VMxxxx network and find nothing connecting to it, even though I’ve got 4 different devices here using that access point (disconnected and reconnected them several times).
airodump-ng -d [APMACHERE] -c 6 mon0
Sample output after 5 minutes

It is my understanding there should be a significant amount more beacons, especially from an AP in the same room.
Any idea what the problem might be?
