mida | MIDA : A Tool for Measuring the Internet

I'm trying to add a component onto my App.js whenever a certain button is clicked. I've been able to do this successfully but now, as soon as I add the component the page refreshes and the component disappears. What am I doing wrong?

Heres the issue on CodeSandBox: https://codesandbox.io/s/github/JojoDuke/miCard-test?file=/src/App.js

App.js

I am working on a school assignment where I have to make a sequential code be concurrent. What the code does is called a MapReduce, more specifically it counts the number of times all words have appeared in all the input files.

• Input: A directory that contains all text files to be processed.
• Output: A directory that contains a text file with the result.

The implementation that we are given is made of 4 stages; Split Map Shuffle and Reduce. The first 3 have to happen concurrently between them and when all 3 of them are finished, Reduce takes place.

Concurrency, apart from happening between those 3 stages, has to also happen inside each one of the stages. In order to do that, we are told to divide the work between a certain number of threads (each stage has its threads).

From now on I am going to talk only about the Split and Map stage, which are the ones I am having trouble with right now.

The Split and Map stage will have one thread for each 'partition' (they will have the same amount of threads because each Split thread will have a Map thread associated), and there will be one 'partition' for each file in the input directory, except for big files, where I'll have to generate a 'partition' every 8 MB.

This exception is what I am trying to solve, let me explain one more thing and I'll get to it.

Since Split and Map have to have the same amount of threads, what I did is create a function that computes the number of partitions that will have to be created, in order to be able to tell Split and Map how many threads do they have to create when I start them.

What Split threads do is take the 'partition' they have been assigned (it will be an entire file in case its size is less than 8 MB) and send it to its associated Map thread line by line (by writing them in a thread-safe queue).

Okay so here's my problem, I thought to make the Map threads (who read from the mentioned queue and do their thing with each line, doesn't matter right now) read from the queue until they read an EOF, meaning that it's asociated Split thread has ended writing it's 'partition' to the queue, but that would only work with 'partitions' that represent an entire file.

So, my questions are:

1. Which options do I have to decompose a file into chunks of 8 MB?
2. How could I make a thread, who's been given a partition that represents the first chunk of many of a big file, know when to stop reading?
3. Since there will be a fraction of time where Map threads will be trying to read from the queue but the Split threads won't have written anything yet, how could I make them 'wait' for something to be written in the queue?

This is the function that counts how many threads are going to be needed, I would like to make it generate an array of file descriptors containing one for each 'partition'

I've written up a custom zsh theme but can't get the color of the background for the activated venv information to match the arrow design (see picture below). I tried fiddling with $VIRTUAL_ENV and can color the area around the venv information, but I can't seem to edit the actual venv information itself.

In this example, I'd like to color the background of the activated venv "midas" (loaded on the first line via an alias) white to match the text ($(username))to the right of it. Here is a screenshot of my terminal and design. If helpful, the code can be found here in my GitHub repo.

Any thoughts or help appreciated. Thank you!

Using Delphi 5 / Firebird 2.5

I am receiving a strange error message from an update statement in one of our legacy application.

value exceeds the range for valid timestamps

This is from a Midas connection, so I don't really have control on the generation of the update SQL itself, the project is also using bpl so it is difficult to debug in Delphi's code like we usually do with single exe project.

I looked at some tracing tools but it looks Firebird itself is limiting the length of the trace somehow.

param29 = integer, ""
...88 more arguments skipped...

Is there a way to get more information from the trace API to see what are these skipped values?

I have created two menus using Pygame-menu. The first one is the start menu (when you open the program).

I am doing a math program for my school project, and I have already prepared the menu for the game and the process of the game, that basically consists in doing endless loop of sums till you fail, giving you 5 points for every correct answer (in the future I have planned to connect it to a SQLite base, because it asks you a name and your age). Anyway, here are the code of the sums and the menu:

[Updated] The problem consists in when I try to make the code of the sums to appear in the window that the menu produces after pressing 'Comencem', the sums appear in the Python Console, but not in the window. I would like it to appear in the window, but I don't know how to do it. Any help please?

I was wondering if anyone could help me with this problem that has been plaguing me.

I am currently using Qt Creator with verion 5.11.3 Qt on Ubuntu to build a project. Every time I try to build I get the error "gl.h: No such file or directory".

The error occurs next to the line in my code that says "#include

I have ran the following code as well and it did not change the outcome

Pytorch documentation provides a concise way to apply MiDaS monocular depth estimation network for depth extraction. But how should I modify their code to extract network representation at some intermediate layer? I know that I could download the model from github and modify forward function to return what I want, but I am interested in the simplest solution, leaving outer code as is.

I'm aware of subclassing the model class and writing my own forward function, like here, but I don't know how to access the class in the code. The model instance is created straight away with midas = torch.hub.load("intel-isl/MiDaS", model_type). Maybe an example of using a forward hook will be easier.

i have make it an slider with 2 image, the first is Gotrade and second Midas. I want when im on first slide to not display the left arrow and when im on second the right arrow to not be displayed.
