drift | drift pitch tracker explorer | Stream Processing library

I am trying to build a simulation of a random walk process with a drift using a loop, however, I am not able to get any outputs and instead I get a length error (number of items to replace is not a multiple of replacement length) which I can't fully understand since I provide a length that will change with how any number of values (N). I am supposed to be able to provide with specific values and then simulate the random walk. Here's my code:

I'm working on a car drift game, which I want to make skid marks with using the pen.

I created a circle, radius 25 around the car that I am using as a reference for where the tires would be, and I need to get the tire sprite to follow the back end of car according to its rotation. I'm trying to adapt the formulas x'= xcosθ−ysinθ, y'= xsinθ+ycosθ but I don't know how to do it.

I set the initial x value as 0 and the y value as -25, but I know this is wrong because it doesn't stay the same when the car is moved and rotated.

Here is my project: https://scratch.mit.edu/projects/535410396/

I have a Google Cloud compute instance running with Ubuntu 18. We had wireshark running tracking another problem and we noticed that every minute something is accessing the meta data server. Three requests every minute: GET /computeMetadata/v1/instance/virtual-clock/drift-token?alt=json&last_etag=XXXXXXXXXXXXXXXX&recursive=False&timeout_sec=60&wait_for_change=True GET /computeMetadata/v1/instance/network-interfaces/?alt=json&last_etag=XXXXXXXXXXXXXXXX&recursive=True&timeout_sec=60&wait_for_change=True GET /computeMetadata/v1/?alt=json&last_etag=XXXXXXXXXXXXXXXX&recursive=True&timeout_sec=77&wait_for_change=True

In call cases, the wireshark says the source is the IP of my instance, and the destination is the 169.254.169.254 which is the Google metadata server.

I don't have any code we have written that is accessing the server. The first one makes me think that this is some Google specific software that is accessing the meta data? But I haven't been able to prove that. What is worrisome is that the response for the third one contains ssh keys. Also, every minute seem excessive.

I see another post talking about scripts in /usr/share/google, but I don't have that directory. I do see that google-fluent is installed. I also see a installed snap for google-cloud-sdk. Could one of those be it? I don't recall installing them, AFAIK, I am not using it, so if that is it, what is the harm in uninstalling it?

I have a workout timer that lets the user workout for 30 seconds & then break for 10 seconds. I have some visual aspects that represent this with some Text saying whether it's a break or a workout time. When the timer first starts it works good, but over time it drifts off & the text begins to be changed early then it should. I'm invalidating my timers once they are done, I can't see why I would be getting different results just because time has passed.

Consider the following MWE:

I am trying to send some commands to a Terminal through UART, so in order for the MSP430 to know which command he got, I wrote some if-conditions in case cREC_BUFFER contains a certain word, the microcontroller should controller it then, for example if the string cREC_BUFFER contains the word "ENDE" at the end, he should go into the if condition inside. The problem that I am facing, is that when I check what the string empty string cREC_BUFFER has after debugging, it contains only the last character "E" of the word "ENDE". Can someone tell me what mistakes I am making here? Thanks a lot for the help in advance! (I reduced the length of the code in here by deleting the content of the other functions, since they do not cause the problem)

I'm trying to create a periodic function but I get:

MethodError: no method matching

First of all I have no idea how TTF files are organized so I might have some of my terminology wrong here.

I have a stylesheet with a @font-face that references a single TTF file that has multiple faces in it. In the Windows font viewer it looks like this if I cycle through "next" (sorry, GIF got messy, picked bad encoding parameters, didn't feel like redoing it, but you get the drift):

The file has a .ttf extension although I'm not sure what the relationship is to OpenType (it says "OpenType" in that window).

Anyways, I reference it like this in the stylesheet:

I have 6 columns and 3 categories I cannot make the columns group on the categories. Can I call the category from within the Series?

My goal is to group MACD BUY and MACD SELL in the MACD category side by side, SMA 7/35 BUY and SMA 7/35 SELL under SMA 7/35 category, etc. You get the drift.

Sorry about below format, I cannot make the snippet feature work. Here is the JSFiddle: http://jsfiddle.net/worb5gyz/
