Microsoft Copilot Studio Agent – Severe Latency with SharePoint Knowledge Sources (20–30s Response Times)

17 March 2026 @ 2:57 am

SharePoint Knowledge Source (50–60 documents) I created a Copilot Studio agent with a SharePoint connector pointing to ~50–60 documents (a mix of .aspx pages and Word/PPT docs). When I ask relevant questions in the Agent Test Panel, responses take 20–25 seconds. When the agent is integrated into an application, latency climbs to ~30 seconds. I have not found any configuration in Copilot Studio to improve this latency. The agent configuration doesn't expose obvious performance tuning knobs. Is there any way to reduce response time for an agent grounded on 50–60 SharePoint documents? Are there configuration settings, architectural patterns, or feature toggle. Important note: This is not purely a document-count issue. Even with only 10–15 documents, the agent still takes ~15 seconds to respond. Scaling down the knowledge source does

Tell me about c language

17 March 2026 @ 2:56 am

I want to learn the C programming language properly from the beginning. Please explain what C is, why it is important in computer science, and where it is commonly used. Also guide me on the best way to start learning C as a beginner, including the basic topics I should study first and the order in which I should learn them. I would also like to know how I can improve my C programming skills faster through practice, projects, or problem-solving methods. Please explain some of the advanced features of C, such as pointers, memory management, structures, file handling, and dynamic memory allocation. Finally, after learning C, which programming language should I learn next to further improve my programming and software development skills? Please suggest languages that are useful for students and developers, such as C++, Python, or Java, and explain how they help build stronger programming knowledge.

Develop a Command Interpreter for their prototype robot

17 March 2026 @ 2:31 am

You’ve been recruited by the Robotics Division to develop a Command Interpreter for their prototype robot. This robot can perform complex tasks—but only if the instructions are syntactically perfect. Your job is to write a program in the language of your choice (or adapt parse.cc) that checks whether a user-submitted instruction follows one of the five approved syntactic patterns. If the instruction is valid, the robot will execute it. If not, your program must diagnose the error, explaining which part of the syntax is broken and why the robot would misinterpret it. Instruction Rules/Patterns Your robot understands only the following formats: 1️⃣ <Time> <Behaviour> <Object> e.g., "2seconds push block" 2️⃣ <Object> <Colour> <Behaviour> e.g., "car red lift" 3️⃣ <Weight> <Behaviour> e.g., "heavy pull" 4️⃣ <Time> <Dir

C clang code fails on mac - with no error. Simply prints out "2", then the first two characters in a file

17 March 2026 @ 2:22 am

I can't explain the problem any further. This is literally the end of my knowledge. What happens with the program is that it prints out "2" on a newline, then the first two characters in a file. This appears strange, because there is no obvious error with the program. I have tried simplifying my program, but it fails even in this simplified form. I am considering giving up at this point. This isn't even a joke, I'm just not sure what's wrong with my computer that would make this code not compile correctly. (I've tried error handling - there is no error). #include <stdio.h> #include <stdlib.h> #include <stdint.h> typedef int32_t i32; int main(int argc, char **argv) { FILE *file = fopen("Makefile", "rb"); fseek(file, SEEK_END, 0); i32 filesize = ftell(file); fseek(file, SEEK_SET, 0); fprintf(stderr, "%u\n", filesize); char *text = mal

can you help Create a memory management program using either the fifo page replacement approach or the lru approach

17 March 2026 @ 2:12 am

can you help Create a program in any programming language you wish that performs memory management using either the first in first out page replacement approach or the least recently used approach. The user should enter the sequence that the pages are called and the number of page frames in the RAM. The program should output how the pages are stored in RAM overtime in the form of a table and the page faults created. Below is just an example of how the output might be shown (this uses the random page replacement approach).

Manual code signing with ssl.com certificate

16 March 2026 @ 11:38 pm

I am trying to manually sign code with an ssl.com code certificate. I am using the Windows signtool to do the manual signing. According to the documentation, I must first run esignerCKA.exe which will automatically import the ssl.com code signing certificates in the Windows certificate manager. This step does not appear to work, so I doubled clicked on the certificate in the esignerCKA and installed the certificate. Once I did this, I see the certificate in the Windows certificate manager. Next, I use the Windows sign tool to manually sign the tool. The sign tool cannot find the certificate because it doesn't have a private key. According to the documentation it should get the private key from esigner. Here are the documents on how to manually sign the code. Has anyone successfully manually sign code using

How to print an image on an ESC/POS thermal printer in .NET MAUI?

16 March 2026 @ 10:13 am

I was trying to print an image using ESC/POS commands in a .NET MAUI application but the printer only prints text correctly. Images require conversion to monochrome and ESC/POS byte format. What is the correct workflow for converting and printing an image to an ESC/POS thermal printer in .NET MAUI? I am building a .NET MAUI application where I need to print images (such as logos or QR codes) on a thermal receipt printer. Most thermal printers support ESC/POS commands and require the image to be converted into a monochrome bitmap format before printing. I want to understand the correct workflow to: Load an image from a file or URL Convert the image into monochrome (black & white) Convert the image into ESC/POS compatible byte format Send the byte array to the thermal printer What is the recomme

2026 Predictions: The Next Big Shifts in Web Accessibility

22 December 2025 @ 11:22 pm

I’ve lived long enough, and worked in accessibility long enough, to have honed a healthy skepticism when I hear about the Next Big Thing. I’ve seen lush website launches that look great, until I activate a screen reader. Yet, in spite of it all, accessibility does evolve, but quietly rather than dramatically. As I gaze […]

Up and Coming ARIA 

30 May 2025 @ 6:19 pm

If you work in web accessibility, you’ve probably spent a lot of time explaining and implementing the ARIA roles and attributes that have been around for years—things like aria-label, aria-labelledby, and role="dialog". But the ARIA landscape isn’t static. In fact, recent ARIA specifications (especially ARIA 1.3) include a number of emerging and lesser-known features that […]
