flood | ReactJS frontend web application for monitoring USGS | Frontend Framework library

We have our app deployed in Cloud Run which is schedule to run through cloud scheduler every half n hour but recently we are flooded with 401 and 403 errors . These are the new and recurring errors that have been spamming our alert system. We noticed some malicious hits made by third party to invoke our Cloud Run Service .

The remote IPs of the invoker (which is getting rejected each time due to not having the correct permissions to invoke pipeline executions) are consistent with a malicious party who is known for trying to disrupt or gain access to unsecured endpoints and resources online.

Details of the unauthenticated requests: Error - 401 - 209.17.96.*** - userAgent: "Mozilla/5.0 (compatible; Nimbostratus-Bot/v1.3.2; http://cloudsystemnetworks.com)" Error - 403 - 209.17.97.*** - userAgent: "Mozilla/5.0 (compatible; Nimbostratus-Bot/v1.3.2; http://cloudsystemnetworks.com)"

what could be a possible solution to restrict/blacklist these Incoming Traffic from our Cloud Run service ?enter image description here

I'm writing a pipeline in Snakemake that calls an R script. This R script has its own environment, with r-base, r-ggplot2 and r-biocmanager in it. I also need the package ggbio that can be installed with biocmanager. I want to silently install this package when the script is called because I don't want it to flood my terminal. Is there a way to do this? I have this right now, but this still outputs instalment information to the terminal:

I have a rectangle and a circle on its left side. Both are white.

I'm trying to create a drop shadow on the rectangle and a drop shadow on the circle which is on top of the rectangle left part.

I am creating a pixel art editor for Android, and as for all pixel art editors, a paint bucket (fill tool) is a must need.

To do this, I did some research on flood fill algorithms online.

I stumbled across the following video which explained how to implement an iterative flood fill algorithm in your code. The code used in the video was JavaScript, but I was easily able to convert the code from the video to Kotlin:

Here is an excerpt of the JavaScript code from the video:

I'm working on a web application for a disaster management lab assignment that is using the Google Places and Maps JavaScript API. The goal is to have markers on the map which are attached to an event listener which is supposed to show an information window with the data about a disaster report. However, the window is not showing up when I click on the marker. The pointer finger icon shows when I hover over a point, yet no information window appears when I click on the marker. There are zero errors in the dev console when I run it through IntelliJ and Tomcat, and I tried changing addListener to addEventListener but it still doesn't work. I will post my code below but let me know if you need anything else to help. For security reasons, I have replaced my API key with MY_API_KEY, so I guess you will have to have access to the Google API's yourself in order to help so I apologize for that. Thanks!

P.S. When I tried creating the snippet it came up with the following error which I'm unsure where the error is coming from because there is no line 302 in the JS code: { "message": "Uncaught SyntaxError: Unexpected end of input", "filename": "https://stacksnippets.net/js", "lineno": 302, "colno": 5 }

Here's what the information window is supposed to look like:

I am trying to build an SVG something similar to:

The strokes are completely dynamic, as they come from an API. I want to place the strokes at the points received (as array of percentage values). Need not be in order and the distance between 2 strokes need not be equal

I am trying with something like below but not able to come up with a logic for the placement of strokes. I tried to follow the answer here: https://stackoverflow.com/a/66076805/6456247 but the distance between strokes here are equal. In my scenario, they are not consistent.

I am new to Ethereum and generally to blockchain. I learned that Ethereum blockchain works on Kademlia. The distributed hash table and its working was beautiful and nicely explained by Eleuth P2P.

Now I used geth to connect to the Ethereum Mainnet and it discovered 2 to 3 maximum peers in 5 to 6 minutes.

Now I know the algorithm but my concern is how the first peer is discovered? Because internet is just a big set of routers and different type of computers (server, computer, etc ) and if you broadcast the discovery like in ARP. The internet will be flooded with these peer discovery broadcast messages and this doesn't seems right. So how initially the connections are made? Also we cannot trust a single network for first time connection because this will make the system server and client based and not decentralised so how the initial connections and peer discovery happens?

Are the broadcast message like have TTL like to prevent the circular loop like in TCP I guess? But this also seems a horrible idea to me.

Please explain.

I'm using docker-compose to run tests for my app. My docker-compose.yml file has three services, one for mongodb, one for my app, and a third for my tests. I have logging: driver: "none" set for the app and mongodb because I only want to see the test logs.

This previously worked as expected. Since the last time I worked on this project, I've upgraded docker desktop on my mac to Version 3.5.2 (3.5.2.18). Now, all container logs flood my terminal when running. I'm not sure what has changed.

How can I decode rosbridge data in the browser?

So far ive been able to decode the following types:

• Uncompressed raw RGB
• Uncompressed raw Depth
• JPEG compressed RGB

My Problem now is decoding compressed depth and PointCloud2 data. As far as my understanding goes, the data is encoded as base64. The depth image has been compressed to a mono16 PNG. I have tried many different approaches, but none seem to work. The depth image is supposed to contain 307200 depth values of 16 bits each.

I do not want to display this data in something like ros3djs or webviz (cloud not figure out how they do the decoding). I want to decode the data and use it in my own analysis.

Steps to reproduce:

Here is a sample file. It contains the data field of the JSON message: https://drive.google.com/file/d/18ZPpWrH9TKtPBbevfGdceZVpmmkiP4bh/view?usp=sharing

OR

1. Make sure you have a device publising or a rosbag playing
2. roslaunch rosbridge_server rosbridge_websocket.launch
3. Launch your web page and make sure you added roslibjs in your script tag

The JS of my web page is simplified to this:
