I'm a decade iOS veteran but new to Swift/SwiftUI so please be gentle. One thing I'm confused about is why a View (I've tried a few but let's use TextView() for example) appears to not be drawn if the opacity is set to zero or the .background(Color.clear).

What I'm trying to accomplish is to put two buttons in an HStack as the first member in a ZStack (so "back" most) in order to determine when the user double taps the left side of the screen or the right, but I don't want anything to actually be shown, just detect the taps. My hackish solution is to set opacity to 0.001. With that opacity setting nothing is visible and I can detect with .onTapGesture(count:2) but surely this isn't the optimal way. In UIKit land I'd be tempted to just process the tap coordinate myself using screen dimensions to determine which side it landed on, but I don't think that's terribly "swifty" even if it's possible without wrapping UIKit classes. Trying to learn, so doing everything as "pure SwiftUI" as possible.

I am trying to build my own script to check some Windows services (status and start mode) and I am facing an issue on the IF ... For example even if the service is "Running", it will never run the code inside the IF...

let me share my code below (I am a newbie on powershell so be gentle xD)

For info, I will do more actions inside the IF and ELSE, it is just for the example.

I have a strip of WS2811 adressable RGB leds and I am trying to control them using my raspberry pi. I am programming in java. To access the GPIO I am using a java library called Pi4j (version 1.2; java 8). This version has built-in PWM control.

My question is the following: How can I send the data to the leds trough a GPIO pin?

I have a table in R which has a column containing a string value which i need to tokenenize into 4 separate columns which would have a 0 or 1 in them depending on whether a token was present. For example

a,b,c,d are all the tokens

a column could have any permutation of the tokens in a string e.g.

a,c b,d c,a

what i want is to turn

This is my first question, so please be gentle :)

I know my question is similar to many others, and I have tried a LOT of solutions, but I'm not getting the result I need.

I have an array of objects that can have duplicate id's. There are 3 objects for id 'THOM01':

I'm a PowerShell newbie so please be gentle! I'm looking to bulk rename a collection of files, then pad the first digits so that they play in order on my devices.

For example, I have a folder full of mp3s ABCDEF_S3L1_010221_GHIJK.mp3 through ABCDEF_S3L49_210921_GHIJK.mp3

I'm trying to rename them as 01-lesson.mp3 through 49-lesson.mp3 where the digit after the L is the prefix but I trip up with the padding for lessons 1-9 so they play out of order, i.e. 01 then 10, 11, 12 etc. I've tried using variations of .PadLeft and {0:D2} but keep getting errors such as:

I have two CSV files. One that contains Vendor data and one that contains Employee data. Similar to what "Fuzzy Lookup" in excel does, I'm looking to do two types of matches and output all columns from both csv files, including a new column as the similarity ratio for each row. In excel, I would use a 0.80 threshold. The below is sample data and my actual data has 2 million rows in one of the files which is going to be a nightmare if done in excel.

Output 1: From Vendor file, fuzzy match "Vendor Name" with "Employee Name" from Employee file. Display all columns from both files and a new column for Similarity Ratio

Output 2: From Vendor file, fuzzy match "SSN" with "SSN" from Employee file. Display all columns from both files and a new column for Similarity Ratio

These are two separate outputs

Dataframe 1: Vendor Data

Company Vendor ID Vendor Name Invoice Number Transaction Amt Vendor Type SSN 15 58421 CLIFFORD BROWN 854 500 Misc 668419628 150 9675 GREEN 7412 70 One Time 774801971 200 15789 SMITH, JOHN 80 40 Employee 965214872 200 69997 HAROON, SIMAN 964 100 Misc 741-98-7821

I am trying to learn Common Lisp with the book Common Lisp: A gentle introduction to Symbolic Computation. In addition, I am using SBCL, Emacs, and Slime.

In chapter 14, the last one, the author covers macros. The following problem is presented:

Write a macro called VARIABLE-CHAIN that accepts any number of inputs. The expression (VARIABLE-CHAIN A B C D) should expand into an expression that sets A to ’B, B to ’C, and C to ’D.

The answer sheet is:
