notetak | Notetaking app inspired by Notational Velocity

i'm having trouble figuring out how to have each example have a modal with it's own content. currently, if i click EXAMPLE2, the content from EXAMPLE1 still pops up. i also am not sure why the icons or the modals don't work on here, but i'm hoping someone can at least give pointers based on the code here. i tried changing the IDs to be unique, but i don't think i'm doing it correctly? thank you in advance

I am building a simple graphql express setup by following this tutorial:: https://blog.bitsrc.io/how-to-build-a-note-taking-app-with-graphql-and-react-part-1-of-2-febf1aeda091

But some errors are coming:

I'm developing a simple Jupyter extension that only contains a JS file---https://github.com/yifanwu/notetaker/. Currently, it works if I clone the repo and then do jupyter nbextension install.

However, we wanted to streamline the process with pip, so I added https://github.com/yifanwu/notetaker/blob/master/setup.py

However, I realized two issues

1. We still need to run jupyter nbextension install it seems even after the pip install?
2. Running jupyter nbextension install bugs out with FileNotFoundError: [Errno 2] No such file or directory: 'notetaker'

Help is much appreciated. Thanks!

I am new to Android and programming as a whole and I need a little help with callbacks. I understand the gist of callbacks but I am unsure of how to go about implementing.

Context: I am writing a simple notetaking app that allows the user to write text and saving it to the app. The user can then request to read the file with a button. The text is then displayed on a textview in the main activity. There is an option to wipe this file and this is done with a confirmation pop up, which is another activity. This pop up contains 2 buttons, one to cancel and one to wipe. If the file is not empty it will wipe and does nothing if empty. I am not sure if this is the best way to implement it but I want to use the wipe button to callback to the main activity to clear the textview. The way I was thinking of was by using the callback to send a boolean value back. The main activity will check if the boolean is true and clear the textview if it is. I am unsure of how to implement the callback in my popup display to send this boolean value back to the main activity.

Code for main activity

I am currently reading Jon Erickson's book "Hacking: The Art of Exploitation, 2nd Edition" and I am stuck on a problem concerning an exploitation of a buffer overflow.

Firstly, we have a code of notetaker.c (https://github.com/intere/hacking/blob/master/booksrc/notetaker.c) which writes in the file /var/notes

Secondly, we have a code of noteseach.c (https://github.com/intere/hacking/blob/master/booksrc/notesearch.c) which reads in the file /var/notes.

To compile and use it:

While my code works from the functionalities, I have to click "refresh" after each click to see the changes. For example when I click "Add note" I have to refresh the page in order to see it. While it compiles successfully, the console shows three errors:

I'm writing a simple Django powered notetaking app and I'm using martor for markdown and syntax highlighting:

so when you click on one of the notes, it gets displayed in the rightmost area. This currently works as follows: whenever you click one of the notes, an AJAX request is fired which calls a Django view that renders that specific part of the page:

I've been working my way through The Art of Exploitation by Jon Erickson, but I've come to a sticking point regarding reading data from a file and his code.

There are two programs ./notetaker and ./notesearch, the former is used to create a note with the users id, the latter is used to retrieve notes by the current user.

However, after making a note and trying to access it through ./notesearch, the note isn't displayed as text as suggested in the book.

What I have deduced so far is that the file that is created in ./notetaker is a data file as opposed to a text file, so when it is printed out it is not readable.

So why is the author suggesting that his code works, when in reality it doesn't and what would be the simplest work around.

I have started looking at fopen, fgets() etc as the solution, but it seems to be far removed from the original code.

If I get ./notesearch to look at a random text file it will print out in human readable form, so the problem I believe lies in the creation of the original file and its type.

But unfortunately I am none the wiser as to how to overcome the problem

I don't know why: the makemigrations command works fine but when I insert something from the browser, the terminal outputs error message...
