QUESTION
I've created a form so the user can add a new picture to the website catalog, but for some reasons it doesn't work. Once the form is filled out, I click on the 'Submit' button but nothing happens, I just stay on the same page (and I don't have any error message...). I don't think the error comes from my Controller since nothing happens when I add the raise keyword in my Controller's 'create' method.
I'm sure this is an amateur mistake... but I can't see what it is. Thanks for your help!
picture.rb / Picture model:
...ANSWER
Answered 2021-Feb-21 at 02:56Not quite sure why this is happening, but form_for is deprecated, so you should replace it with form_with.
You can use a model, such as your @picture with form_with as described in the docs.

This is my code, based on https://www.instructables.com/id/How-to-use-DS18B20-Temperature-Sensor-Arduino-Tuto/ :
...ANSWER
Answered 2020-Sep-30 at 08:24Some platforms do not implement yield so you can remove the call to it from the code of the library. Calling yield passes control to other tasks, if you do not have other tasks, it is redundant anyway.
Removing it can be done by providing an empty implementation at the top of the file.
If you are sure that your board should support it. Than it is possible that you are using a wrong software stack. Try to download the official Arduino IDE.
QUESTION
I'm trying to set up a startup lifecycle configuration for a SageMaker sketchbook (which just ends up being a .sh file), and it seems like, regardless of what I do, my notebooks timeout on startup. I simplified everything as much as possible, to the point of commenting out all but #!/bin/bash, and I still get a timeout. Checking cloudwatch this shows up in the log:
ANSWER
Answered 2020-Aug-11 at 16:55This is, indeed, to do with special character representation in different os' based on this you can use notepad++ to easily convert the dos representation a unix representation, then just "paste as plain text", and it works fine
- copy to notepad++ view
- show symbol
- show all symbols
- replace "/r" with nothing CRLF should become LF which is valid in unix
- copy and paste as plain text
Doing this fixed the problem

I'm using the Mozzi lib (http://sensorium.github.io/Mozzi/) as part of a tutorial (http://www.echanter.com/home/howto-build#TOC-Arduino-IDE). I included the Mozzi in Arduino Studio and followed minor configs in the tutorial. I've looked around the lines that are reported, but I'm stumped. Compile error is:

QUESTION
I am creating a design with my QGraphicsitems . I have selected all the items in the scene and pasted it.But it is not following the same pattern.can we make the items paste in the same pattern like the one which we have created initially? –
I have tried with the following code
...ANSWER
Answered 2019-Aug-09 at 20:30QGraphicsItem.setPos() is absolute to the scene (or relative to its parent), the alternative solution is to use moveBy(x, y) (which is the same as setPos(self.pos() + deltaPos), but you have to take into account the relative position of the click according to the reference point.
I'd suggest you to not set the position until all items have been added, and then set their position according to a specific item that will be used as an "anchor" point.

...ANSWER
Answered 2019-May-07 at 14:34You have duplicated elements in your input. setdiff returns the unique elements (since it's looking at sets). So 'query' didn't remove anything - you're just getting the output that should match unique(L) since "Waterbrook Reserve Chardonnay" is in your list twice.

I have a python program on my Raspberry pi 3B+ witch updates an Arduino mega2560 and an Arduino Uno by using Arduino-mk through bash commands. Each Arduino has its own code folder with its code (.ino) and a Makefile which looks like:

Answered 2019-Apr-22 at 19:20Plug in one device at a time and look at the output of ls -l /dev/serial/by-id/, you should see a symlink to the actual device node, but uniquely named for your specific device.
You can then set ARDUINO_PORT=/dev/serial/by-id/unique_name in the respective makefiles.

Install sketchbook
You can use sketchbook like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
