QUESTION
I'm working on an aws/amazon-freertos project. In there I found some unusual error "A stack overflow in task iot_thread has been detected".
Many time I got this error and somehow I managed to remove it by changing the code.
I just want to know what this error means actually?
As per what I know, it simply means that the iot_thread ask stack size is not sufficient. So it's getting overflow.
Is this the only reason why this error comes or can there be another reason for this?
If yes then where should I increase the stack size of the iot_thread task?

Either it is insufficient you your stack usage is excessive (due to recursion error or instantiation of instantiation of large objects or arrays. Either way the cause is the same. Whether it is due insufficient stack or excessive stack usage is a matter of design an intent.
If yes then where should I increase the stack size of the iot_thread task?
The stack for a thread is assigned in the task creation function. For a dynamically allocated stack that would be the xTaskCreate()
call usStackDepth

QUESTION
I've joined 2 tables and extract the top 2 vendors by country (code at the bottom of this post and link) with the help of Tim Biegeleisen on this link , now I would like to go 1 step further and group the top 2 vendors by year by country.
The original ORDERS table looks like this :
country_name date_local vendor_id gmv_local is_successful_order Taiwan 2012-10-02 2870 559.6 true Taiwan 2012-10-02 3812 573.5 true Singapore 2012-10-02 941 778.6 true Singapore 2014-10-02 13 120.6 true Bangkok 2014-10-02 227 563.6 trueThis table is merged with the vendor table
id vendor_name country_name 2870 C House Taiwan 941 A House Singapore 227 9 House BangkokI would like to extract the year from the "date_local" column into timestamp format, where the items in the Year column will look like "2012-01-01T00:00:00" from the original date format of "2012-10-02"
Then I would like to list out the top 2 vendors of by year of each country in total revenue
The resulting table should look like this:
year country_name vendor_name total_gmv 2012-01-01T00:00:00 Singapore A House 1119.76 2012-01-01T00:00:00 Singapore B House 819.63 2012-01-01T00:00:00 Taiwan C House 119.6 2012-01-01T00:00:00 Taiwan D House 119.6 2012-01-01T00:00:00 Bangkok 9 House 119.6 2014-01-01T00:00:00 Singapore A House 2119.76 2014-01-01T00:00:00 Singapore B House 1819.63 2014-01-01T00:00:00 Taiwan C House 1019.6 2014-01-01T00:00:00 Taiwan D House 919.6 2014-01-01T00:00:00 Bangkok 9 House 189.6I know I need to add one more partition of the Extract( year FROM date_local) as year
and set it to the correct GETDATE()
timestamp format to add the extra layer needed, but I don't know how to add it to the code
ANSWER
Answered 2021-Jun-10 at 05:11If I understand correctly, you only need to also aggregate by year, and then add year to the partition of the call to ROW_NUMBER

I am doing a query on Google Big query, I have joined the 2 tables and created a new column "total gmv" using "SUM" to represent the total revenue, now I wanted to show only the top 2 vendors , GROUP BY country in my query.
I manage to show total_gmv group by COUNTRY and vendor_name, but I would like to filter to show top 2 vendors for each country only.

I have been working on a I/O bound application which is a web crawler for news. I have one file where I start the script which we can call "monitoring.py" and by choosing which news company I want to monitor I add a parameter e.g. monitoring.py --company=sydsvenskan
which will then trigger sydsvenskan webcrawling.
What it does is basically this:
scraper.py
...ANSWER
Answered 2021-Jun-07 at 09:53The universal answer for performance questions is : measure then decide.
You ask two questions.
Would it be faster to use dynamic imports ?I would think so, but in a very negligeable way. Except if the computer running this code is very constrained, the difference would be barely noticeable (on the order of <1 second at startup time, and a few dozens of megabytes of RAM).
You can test it quickly by duplicating your sydsvenskan.py
file 40 times, importing each of them in your scraper.py
and running time python scraper.py
before and after.
And in general, prefer doing simple things. Static imports are simpler than dynamic ones.
Can PyCharm still provide code insights even if the import is dynamic ?Simply put : yes. I tested to put it in a function and it worked fine :
QUESTION
I am trying to use vuejs-datepicker
in a nuxt app, everything is done by nuxt plugin usage standarts.
plugins/vue-datepicker.js
ANSWER
Answered 2021-Mar-01 at 16:18So yeah, there is basically a feature request open for this kind of use-case.
But looking at the Nuxt lifecycle, it looks like the plugins are imported even before the VueJS instance is done. So, you cannot lazy load it if it's done ahead of Vue.
But, you can totally import vuejs-datepicker
on the page itself, rather than on the whole project. This may be enough

I'm trying to make a web page that starts with a image next to some text. I got that to work but when I try to put content under that it works on desktop but when the columns get stacked the content below covers the second column. I don't do a heap of web design so this might be a easy fix.
Here are some images: These images are scrolled down the image fill the whole viewport.

...ANSWER
Answered 2021-Jun-04 at 09:56While creating the task iot_thread
(presumably by calling xTaskCreate()
or xTaskCreatePinnedToCore()
) you've allocated insufficient stack space. Since you haven't posted the code where you create it, I can't be more specific. Start by increasing your current stack 2 times, see if it still crashes. If that doesn't help, repeat.
The usual approach for determining a task's stack size is to set the stack very large (perhaps 8-16 KiB) and let the task run its more stack-intensive stuff for a while. Then use the task monitoring functionality in vTaskGetInfo()
to see how much unused stack it has. Finally you can reduce the stack size to the actually used amount plus a sufficient reserve. I tend to keep 1-2 KiB of stack in reserve.
