QUESTION
I'm learning C++ and have come to a bit of a halt. I'm trying to iterate over a vector with a range-based for loop and update a property on each of the objects that belong to it. The loop is inside of an update function. The first time it fires, it works fine; I can see the property gets updated on each member of the vector. However, the next time the for loop is initiated, it's still updating the original data, as if the previous run did not actually update the source values. Is my range declaration configured correctly? Pointers are still a bit of a mystery to me. In general I'd be very thankful for any help!

Answered 2021-Jun-15 at 23:19Vector3 position = point.position;
makes a copy of point.position
. The following code then updates this copy, which in turn is thrown away when it goes out of scope at the end of the if
statement.
The solution is simple enough - use a reference instead: Vector3 &position = point.position;
. The rest of the code can be left as-is.
QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events
snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:
10:54:12.642 AM Function execution started
10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating
10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating
10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'
10:54:14.148 AM
Super hyggelig aften :)
super oplevelse, ... long string generated
Gist showing the function in question
I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon

QUESTION
Update: Added a simpler demonstration jsfiddle, https://jsfiddle.net/47sfj3Lv/3/.
reproducing the problem in much less code I'm trying to move away from jQuery.
Some of my code, for populating some tables, has code like this
...ANSWER
Answered 2021-Jun-15 at 18:27This was difficult for me to understand, so I wanted to share if anyone else has the same issue.
It seems that an async method will break a method chain, there's no way around that. And since fetch is asynchronous, await must be used, and in order for await to be used, the calling method must be declared async. Thus the method chain will be broken.
The way the method chain is called must be changed.
In my OP, I linked https://jsfiddle.net/47sfj3Lv/3/ as a much simpler version of the same problem. StackOverflow's 'fiddle' effectively blocks 'fetch' for security reasons, so I need to use JSFiddle for demonstration.
Here's a working version of the same code using then
and how/why it works, and a slightly shorter version, because await can be specified with the the fetch, obviously.
QUESTION
How do I produce an animation that simulates the burning effect of fire consuming an UIView
from top to bottom in Swift?
I found Fireworks, an app that allows users to tweak and try out different settings of CAEmitterLayer
with instant results. The effects are great for applying to a whole screen but how would I use it for my purpose - where the UIView
must disappear as the fire consumes it from one end to the other?
Is there some tutorial on consuming UIView
s with fire using the particle emitter anywhere? I know that I’m supposed to show some code but anything I put here would be irrelevant. I’ve also exhausted my search engine looking for something similar. That’s how I found the Fireworks app actually.
This seems to be a use case that shouldn't be uncommon.
...ANSWER
Answered 2021-Jun-14 at 14:24I was once in your shoe before and came across this Open source library called particle animations.
I would NOT recommend using the library itself since it's deprecated. But I would recommend referring to its source code to get an idea of how to use CAEmitterLayer and CAEmitterCell
to make the looks of a Fire!
As you could see from its readme, it has direct examples of Fire. It also states that even Apple and Facebook uses CAEmitterLayer and CAEmitterCell
to produce the effect of a fire.
Feel free to ask for more questions.
QUESTION
How to remove VIM (completely) and change my mac command line editor to sublime?
I've spent the last three hours reading the same links on "how to remove VIM" only to get "how to remove MacVIM and reinstall it fresh" Or "How to remove Vim so I can reinstall it on Ubuntu"
My old laptop was fortunate to have a friend remove it but my new machine still has it installed.
I wish VIM would die in "words redacted to excessive profanity" dumpster fire while a hobo "words redacted to excessive profanity" to put out the fire
I've lost way too many hours trying to learn that outdated neckbeard elvish piece of UX trash so I want it gone. No, I'm not touching emacs.
Please tell me there is a way I can switch to sublime or am I permanently cursed to have this confusing black screen of death pop up when I try to git push or git tag stuff?
My original goal was to tag a git and push it but vim comes up and I can't figure out how to speak elvish.
I've been using PyCharm for a few years and love the interface but I need to dig deeper and a TDD Django book for class uses the terminal, it wants me to git -a "comments" so I need your advice.
So now I can't learn TDD Django because vim, MacVim and eMacs users flood the internet but I can't remove it nor figure out how to work it.
I've tried brew uninstall macvim
which doesn't work because I have vim not macvim
I also tried sudo uninstall vim
no luck as this is zsh mac not ubuntu
I tried brew uninstall vim
to get No available formula or cask with the name "vim"
I've searched SO five times and keep getting the same links.
Alternates I've tried
brew uninstall ruby vim
per this post https://superuser.com/questions/1096438/brew-upgrade-broke-vim-on-os-x-dyld-library-not-loaded I tried, no luck.
...ANSWER
Answered 2021-Jun-14 at 21:41You don't have to remove Vim from your machine. Instead, tell your system and your tools to use Sublime Text as default editor. After you have followed that tutorial, which I must point out is part of Sublime Text's documentation, you should have a system-wide subl
command that you can use instead of vim
. For that, you need to add those lines to your shell configuration file:

I have an application using ASP.NET Core MVC and an Angular UI framework.
I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:

QUESTION
Before anyone says it, I have tried all of the examples I can find, and nothing seems to work so far, so that's why I'm posting a new question.
I am working on an ASP.NET web forms project, and I have a page containing a GridView control that has several command buttons for each record representing different options. One of them is "Subscriptions", which I want to use to display details of a subscription record in a Bootstrap modal dialog. I stripped the modal dialog code down to the bare minimum:

Answered 2021-Jun-14 at 19:36Here is a little example that I wrote which will hopefully give you some insight on how you can fix yours, as I don't really know your GridView setup. Though potentially just adding document.ready()
to your ShowStatus()
might fix this issue.
