How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

VBA - Loading Arrays, Skipping Blanks

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.

Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS.

Segmentation fault while calculating the intersection of two sets

Asked 2021-Jun-15 at 15:05

I need to find the intersection of two arrays and print out the number of elements in the intersection of the two arrays. I must also account for any duplicate elements in both the arrays. So, I decide to take care of the duplicate elements by converting the two arrays into sets and then take the intersection of both the sets. However, I encounter a segmentation fault when I run my code. I'm not sure where this occurs, any way to fix this?

QUESTION

Dangers of mixing [tidyverse] and [data.table] syntax in R?

Asked 2021-Jun-15 at 06:35

I'm getting some very weird behavior from mixing tidyverse and data.table syntax. For context, I often find myself using tidyverse syntax, and then adding a pipe back to data.table when I need speed vs. when I need code readability. I know Hadley's working on a new package that uses tidyverse syntax with data.table speed, but from what I see, it's still in it's nascent phases, so I haven't been using it.

Anyone care to explain what's going on here? This is very scary for me, as I've probably done these thousands of times without thinking.

I came across the same problem on a few occasions, which led me to avoid mixing dplyr with data.table syntax, as I didn't take the time to find out the reason. So thanks for providing a MRE.

Looks like dplyr::arrange is interfering with data.table auto-indexing :

index will be used when subsetting dataset with == or %in% on a single variable

by default if index for a variable is not present on filtering, it is automatically created and used

indexes are lost if you change the order of data

you can check if you are using index with options(datatable.verbose=TRUE)

If we explicitely set auto-indexing :

What you are trying to classify is represented as Action Recognition. Here [1] is a good repo that lists a lot of out-of-the-box models for this task.

An explanation: Models (like YOLO) contain two main blocks: feature extraction (CNN stuff) and classification (linear layers). When training from scratch, both feature extraction and classification will be trained from scratch. It is easy to train classification to what you want, but it is hard to train the feature extraction part (as it takes a lot of time). Hence, we typically use pre-trained models on generalized datasets (like YOLO is trained on COCO), so our feature extraction part starts from a somewhat good generalized place. Later, we replace the classification part will our own to be trained from scratch for our task.

TL;DR, you can use a pre-trained YOLO model on COCO for your task by replacing the last linear layers to classify what you want. Here are some resources for different frameworks [2, 3].

Here [4] is a simple walkthrough of how to do this.

QUESTION

Additional unique index referencing columns not exposed by CDC causes exception

Asked 2021-Jun-14 at 17:35

I am using the SQL connector to capture CDC on a table that we only expose a subset of all columns on the table. The table has two unique indexes A & B on it. Neither index is marked as the PRIMARY INDEX but index A is logically the primary key in our product and what I want to use with the connector. Index B references a column we don't expose to CDC. Index B isn't truly used in our product as a unique key for the table and it is only marked UNIQUE as it is known to be unique and marking it gives us a performance benefit.

This seems to be resulting in the error below. I've tried using the message.key.columns option on the connector to specify index A as the key for this table and hopefully ignore index B. However, the connector seems to still want to do something with index B

How can I work around this situation?
For my own understanding, why does the connector care about indexes that reference columns not exposed by CDC?
For my own understanding, why does the connector care about any index besides what is configured on the CDC table i.e. see CDC.change_tables.index_name documentation

One of the contributors to Debezium seems to affirm this is a product bug https://gitter.im/debezium/user?at=60b8e96778e1d6477d7f40b5. I have created an issue https://issues.redhat.com/browse/DBZ-3597.

Edit:

A PR was published and approved to fix the issue. The fix is in the current 1.6 beta snapshot build.

There is a possible workaround. The names of indices are the key to the problem. It seems they are processed in alphabetical order. Only the first one is taken into consideration so if you can rename your indices to have the one with keys first then you should get unblocked.

JavaScript access child element within forEach loop

Asked 2021-Jun-14 at 13:44

I'm just starting out with JavaScript although I have used a number of other languages previously. I'm finding the orientation pretty painful and I'd appreciate some guidance on how to access child elements within a forEach loop (or a jQuery .each loop). At this stage I don't really care whether the solution is JS or jQuery, I'm just trying to get something that works.

Say I have a node element that I have found using jQuery and I now have some processing to do on each row, which includes needing to find a child-element whose id contains an index related to the parent node in question:

ANSWER

Answered 2021-Jun-14 at 13:43

There are concrete efficiency losses because of the inefficient use of threads. Each thread requires at least 1 MB for its stack, so the more threads that are created in order to do nothing, the more memory is allocated for unproductive purposes.

It is also possible for concrete performance losses to appear, in case the demand for threads surpasses the ThreadPool availability. In this case the ThreadPool becomes saturated, and new threads are injected in the pool in a conservative (slow) rate. So the tasks you create and Start will not start immediately, but instead they will be entered in an internal queue, waiting for a free thread, either one that completed some previous work, or an new injected one.

Regarding your concerns about creating busy waiting procedures, no, that's not what happening. A sleeping thread does not consume CPU resources.

As a side note, creating cold Tasks using the Task constructor is an advanced technique that's only used in special occasions. The common way of creating delegate-based tasks is through the convenient Task.Run method, that returns hot (already started) tasks.
