I am writing an Android application that dynamically generates a simple PDF document and then fires an intent to open an email client (like Gmail) with the recipient, subject, body, and the PDF attached. The Problem: The intent successfully opens the app chooser, and when I select Gmail, the compose screen opens perfectly. The "To", "Subject", "Body", and the PDF attachment are all visible in the compose UI. However, when I tap "Send", it does not actually send. It just goes straight to the drafts folder, and the PDF attachment is missing. Only the plain text remains. What I've Tried (and didn't work): To fix this, I have tried the following based on modern Android (API 30+) best practices: 1. Used `FileProvider` to correctly serve a `content://` URI instead of a `file://` URI. 2. Added `Intent.FLAG_GRANT_READ_URI_PERMISSION` to the intent. 3. Added `intent.setClipData(ClipData.newRawUri("

I have completed porting the Linux kernel on a custom board based on TI AM437x. The kernel version is 6.12.49, and I am using the TI Processor SDK. Now I am trying to develop an application using Qt (Qt6) with Qt Creator. However, I am having difficulties configuring the Kits. I configured the toolchain using the SDK provided by TI: -Device type: Generic Linux Device -Sysroot: /root/SDK/ti-processor-sdk/linux-devkit/sysroots/armv7at2hf-neon-oe-linux-gnueabi -Compiler(C): /root/SDK/ti-processor-sdk/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-gcc -Compiler(C++) /root/SDK/ti-processor-sdk/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-g++ -Qt version: None -CMake Tool: /root/SDK/ti-processor-sdk/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/cmake enter

In TYPO3, the backend layout fields are able to show large thumbnails beneath the dropdown: Is it possible to have these same kind of large thumbnails for other fields, specifically the Layout field of a content element: I know you can add small icons to this dropdown, but they are very small and only display after you've selected an item...

I'm trying to make a barplot using ggplot. I want the bars to show the percentage of models "eaten" by birds for four different color types. I made this one, but thecode makes a stacked barchart and I don't want that, I want it to show only the precentage eaten by birds. #library tidyverse #data df <- data.frame( type = c("black", "brown", "border", "inside"), survival = c("survived", "bird"), n = c(20, 31, 20, 30, 39, 29, 34, 26)) #graph ggplot(data = df, aes(x = type, fill = survival, y = n)) + geom_col(position = "fill") + labs(y = "Počet atrap [%]", x = "Typ atrapy", fill = "Přežívání") + scale_fill_discrete(labels = c("přežil", "pták")) + theme_classic() + scale_x_discrete(label = labels) then I tried this code with the same data, but it doesn't actually show the percentages,

Context I'm just getting back into programming as a hobby, and I wanted to try making a compiler. Im currently making the lexer, and when checking if a token is an operator I use a binary seach to search a vector of operators. I can think of 3 solutions: Using a map for O(1) lookup time, but I already have one that is sorted by operator id so it feels like code redundancy. I could lexocographically sort the vector and use my binary approach I have already programmed. Or I could just use a linear search algorithm which is simpler but Im not very familiar with little o and it feels wrong. I tried using some math and estimating that linear search will on average take n/2 comparisons, and that the binary search will take x * 3log_2(n) because the maximum operator length is 3 and base 2 because its binary, I got the roots as 1.43 meaning the math says its 1.43x faster to use a binary search

I am attempting to inplement a send email function in python 3.14. I'm getting this error: pywintypes.com_error: (-2147467260, 'Operation aborted', None, None) at the code line: mail = outlook.CreateItem(0) total code: import win32com.client as win32 def testEmail(): # Initialize Outlook application #outlook = win32com.client.Dispatch("Outlook.Application") try: outlook = win32.GetActiveObject('Outlook.Application') except: outlook = win32.Dispatch('Outlook.Application') # Create a new email item mail = outlook.CreateItem(0) # 0 represents an email item # Set email properties mail.Subject = "Hello from Python!" mail.Body = "This is a test email sent using Python and Outlook." mail.To = "[email protected]" # Replace with recipient's email address # Send the email mail.Send() testEmail() How do I resolve this erro

I created a massive workbook for a client and parameterized the geography and vintage of my queries in the Power Query Editor so that I can easily make a similar file with different parameters. The problem is I named the queries themselves too specifically (see attached) and now I want to change them but it breaks all of my associated pivot tables and charts. For example, I would like to change ACS_Poverty_County_1YR to ACS_Poverty so that the query names are not misleading when I create an MSA/Zip Code version of the file. This file is way too big to remake so I'm desperate to find a way to fix it. Power Query Names:

I have a Blazor Server application. I have an IHostedService that is meant to do startup tasks in the "StartAsync()" method. builder.Services.AddHostedService<StartupTask>(); It has a constructor injected IServiceScopeFactory. It creates a new scope: var provider = serviceScopeFactory .CreateScope() .ServiceProvider; provider .GetRequiredService<EntityService>() .ReturnMyCtorInjectedProvider() .GetRequiredService<EntityService>(); Where EntityService is a DbContext, which receives a constructor injected IServiceProvider. As far as I know, since EntityService has been derived from a particular scope's IServiceProvider, it should receive an IServiceProivder which is also tied to the same scope, and resolving the same service from it should produce the same behavior as resolving it from the IServiceProvider of the newly created scope, but I get a well known error: "

I have a operation logic to do in two simples steps into a input value. For me it's like a input cleaning operation I would love to do. Inside of my input I have some blocks of numbers, for instance: 548 601 **002** 847 147 Then what I need: Firstly, after the bloc of numbers selected 002 at the left side. Jump the blank space and the block of numbers just after 847, Then remove all the rest of numbers. Secondly, after that be removed. At the final step remove the block of numbers selected include all the rest of blocks of numbers. All these operations are excecuted into one button. Attention: These numbers 548 601 002 847 147 are just an example to help you to understand what I would love to do. <?php $initialValue = $_POST['phpInput']; $searchTermPHP = "002"; ?> <input type="text" id="phpInput" style="width:100em" va
