how can i do these in real time without paying for an actual server
I just learned the basics of AI development and I can't really find any simple product example to implement the stuff that I've learned, any suggestions?
I've been going over Power Apps tutorials for the past few days and couldn't find the right tutorial to do what I was looking for, or at least give me insight as to how to build it. I've coded in Java, Python, and a few other languages for classes in the past, so I wouldn't be in the dark if I had to use something outside of power apps.
What I've been trying to do is create a mobile app that allows the user to write an item from an existing list, write the count, and then add another line to that list. Then, this list could be exported to Excel. For example:
The list of items to choose from would be like
Description | Cost |
---|---|
Wood Fence | $3 / Length Feet |
Vinyl Floor | $20 / Square Foot |
Etc. | Etc. |
In this app, the user should be able to select from a dropdown for a single line, and use buttons or have the option to write in the quantity of the item. Then, they can add an extra line. Finally, export the list, with cost and quantity, to Excel.
If anyone has suggestions as to where I should start or what programs I should use that would be great. I feel like I have been getting nowhere with trying to learn and use Power Apps for this simple purpose.
Hey guys,
So in 7 months in as my job as a graduate developer and it’s gone mostly ok, I however have come to a crossroads as I feel I am being provided work that is way too much for me to handle, I have mostly focused on front end development, working with Web API’s, domain models, Controllers and Services ect but have been tasked with creating EDI Processors and API Wrappers and I just have no clue. I have to state I have had no in-house training for this and have worked more off a buddy system and just to ask for help but is this what a graduate developer should be expected to do as it feels very complex for my level.
Thanks guys
private State getState() {
// returns the state of Mario
//if velocity is greater than 0, Mario is jumping or if he was jumping in the previous state while falling
if (body.getLinearVelocity().y > 0 || ((body.getLinearVelocity().y < 0 && previousState == State.JUMPING))) {
return State.JUMPING;
} else if (body.getLinearVelocity().y < 0) {
return State.FALLING;
} else if (body.getLinearVelocity().x != 0) {
return State.RUNNING;
} else {
return State.STANDING;
}
}
I got this code from Brent Aureli, however, I'd like to know what's causing a problem:
first i know that:
when mario jumps and falls from that jump, he will be continuously in that jump state.
when mario falls off a cliff, instead of going into a jump state, he will go into a falling state.
however, when mario hits his head on a ceiling, his jump state is cut short abruptly?
I've tried setting conditions for whenever y velocity hits 0 which i assume is what happens when his head hits the ceiling, however doesnt velocity hit 0 at the top of a jump as well?
I'm trying to find out if there's a way to keep the jumping state after hitting a ceiling from the jump
I’m not too great at coding, so I need some help in getting this project to work, but also to learn about what the issue was.
It revolves around choosing a random bird based on a color chosen by the user, in which it shows its name, picture and diet. It takes info from a data list, and is supposed to filter the birds to be the ones that fit the criteria.
When I try to run the project, the name and diet end up as undefined and no picture is shown.
I’m pretty sure the problem is in the if statements, but I’m not sure what to do. I would really appreciate any and all help.
Hi,
I’m looking for some help/ guidance on how difficult it would be to create a software program that would use plaid or another alternative to connect to a business bank account and look for specific withdraws and deposits within that account?
Then it would do some basic calculations/ math and that would be used for push notifications. Etc..
I know plaid is pretty popular, but curious if there’s anything better and how expensive this would be to build out.
So ive been trying to add a macro that will flip the sign of a formula or value in excel. It does this by multiplying to cell by -1. However this does work by flipping the sign, it does not remove the parentheses its added surrounding the cell if i run it again to flip the sign again and they just continue to build up if I keep running the macro.
If it keep running the code the formula ends up looking sometihng like this =((((20*2))))
Heres the code
"Sub FlipSign()
Dim rng As Range
Dim cell As Range
' Check if any cells are selected
If Not Selection Is Nothing Then
Set rng = Selection
For Each cell In rng
' Check if the cell contains a numeric value
If IsNumeric(cell.Value) And Not cell.HasFormula Then
cell.Value = cell.Value * -1
' Check if the cell contains a formula
ElseIf cell.HasFormula Then
' If the formula is already multiplied by -1, remove this multiplication
If Left(cell.formula, 4) = "=(-1" And Right(cell.formula, 1) = ")" Then
cell.formula = "=" & Mid(cell.formula, 6, Len(cell.formula) - 6)
Else
' Multiply the entire formula by -1
cell.formula = "=(-1*(" & Mid(cell.formula, 2) & "))"
End If
End If
Next cell
End If
End Sub"
I created another macro that can remove these parentheses
"Sub RemoveParenthesisAndNegativeSign()
Dim cell As Range
Dim formula As String
' Loop through each selected cell
For Each cell In Selection
' Check if the cell contains a formula
If cell.HasFormula Then
' Get the formula in the cell
formula = cell.formula
' Check if the formula starts with "=" and contains a negative sign and parentheses
If Left(formula, 1) = "=" And InStr(formula, "-(") > 0 Then
' Remove negative sign and parentheses
cell.formula = "=" & Mid(formula, 4, Len(formula) - 4)
End If
End If
Next cell
End Sub"
however I would like to combine it into the first macro so it does this
Ex: When macro is run the cell will look like this =(-1*(20*2)). When I run it again I want it to look like this =20*2
Any help? Thanks!
Also anyone feel free to use this code if you would like a FlipSign Macro!
Hey guys so I’m working with XQuery and need a function to remove white space and specialised characters (E.g £@!-?) from the value of a specific XML node such as:
(/… [1]/…. [1]/….[1]/Example) [1]
I need this to be done using SQL Server compatible XQuery functions(I previously tried XPath “replace” but that was not compatible with SQL Server), these include:
Any help would be greatly appreciated,
Thanks guys

There is MAIN, and a package-mini.
Main package is widely using package-mini across the components this with no error as:
import { foo } from "@workspace/package-mini";
But, when I do the same within gatsby-config.ts I get build errors like: ReferenceError: Cannot access 'A' before initialization.
The ugly workaround is just to use a relative path since my packages are private are in the same repo:
import { foo } from "../package-mini";
I'm reading in Gatsby Docs that workspaces are not supported. Is that referring to the config so there is basically no other choices? I tried setting alias but no difference.

Hello dear community.
So me and a few friends are doing a project in physics class in which we created a quadratic function of a jet stream of a hole made in a plastic bottle.
As the code is created by Chatgpt on Python, due to me having not competence in coding, I can't post it on here. Additional Information, im able to edit the parameters as im understanding some basics. I'd share the Github with anyone who is interested.
But as right now, I have the function displayed as a rocket wich lands on the y axis on the moon. I think the theme is kind of off from the original topic. So im looking for cool ideas to display our function.
Maybe some of you have some cool ideas which are more related to our ''problem''.
My friend gave me a cpp project running perfectly fine in visual studio with run button both in release and debug mode (not using cmake), however i want to run in vscode. There i am facing "undefined reference to " errors, he is using tinycbor, the problem is coming from functions of tinycbor. I think it is a linker problem but it sucks i want to get rid of it as soon as possible i dont know what should i do. I think
Is there any way to check or have the same configuration as visual studio for vscode
I tried using cmake but i am not understanding which files to link.

so im currently doing a college work and generative ai just gave me a code where it uses CLOB instead of Varchar, is it going to put my college's connection in any danger? (I really need to write paragraphs inside serveral lines so...)
EDIT: I didnt have a perfect answer yet but apparently its better to use VARCHAR2 cause it can store up to 4000 characters and my text is 1000 wide, so yeah, almost sure varchar2 is better then clob.
I am in dire need of help to do what’s honestly a simple assignment but I don’t know where to even start.
I'm bad at explaining, sorry if it's messy.
I have a section on the left side of my site designated for text, and I'd like to put a picture next to each article on my site. No matter what I tried, the picture gets placed directly next to the article, rather than having some space in between the article and pictures.
Imagine: Article|picture
But I would like it to be: Article picture
Basically to have all pictures in a line on the right, next to their corresponding articles, rather than having them squeezed in.
When I input "s" or "S" instead of stopping, the loop continues infinetly without any user input. This image explains everything
I want to develop an app that generates recipes for peoples food they have left over. It would be a free app with adverts and possibly the option to pay for higher tier accounts unlocking more things.
What would I need to learn to be able to create this?
This would be a side project and happy with it taking some time
Many thanks

Hey everyone,
I'm working on a coding project where I want to create a drone that can track GPS coordinates and provide lighting for outdoor activities like running, biking, and events. I'm looking for advice on how to approach the coding aspect of this project.
Specifically, I want to:
I have been researching various websites and watching videos on how to code a drone using different programs and software, but it all seems too overwhelming for me. If anyone has experience with similar projects or can offer guidance on:
I would greatly appreciate any help or advice you can provide. Thanks in advance for your assistance!
This is what I've gotten so far, and it satisfies me except the background part:
<div style="background: #FFFFFF;border:3px solid #11111c; border-radius: 50px">
<div style="color:#01010c; font-size:25px; margin-left: 10px; margin-bottom: 2px; margin-top: 2px">

<div style="border:2px solid #11111c; margin-right: 10px"></div>
</div> </div>
How would I make a background image instead of a plain color background? This is on Fandom, so url function isn't allowed.
I don't know if this is the right subreddit for this, but I cannot find any better one. Basically my primary goal of this project is to get a program that, when I press down one button, will run two separate button inputs to the computer, and keep these inputs active until I release the initial button. The thing is I need one button to be pressed down slightly before the other. I also don't want the program to interfere with any other inputs I have going on while I am holding down this button. I have absolutely no idea what system library I should use to get this kind of interaction with my system. I would prefer to code in python, but if anyone knows any third party applications that could do this without any code, that would be much appreciated. The reason I am even looking to code this is that every macro software I have looked at so far does not have the option to run a separate command on release of the button. I also have some experience in python, and the reason I am not just learning exactly how to do this is I just want this one program and care minimally about my coding skills after this. If you guys don't want to answer this, Could you direct me to a better subreddit?
I was looking into getting a cheap laptop for coding while im away from my PC but an iPad would be nice for other things too. Is there a way to code on an iPad?
