QUESTION
I am trying to learn Golang via project based learning. The problem I have placed before myself to simulate customers adding products to their cart. Currently, I have the Cart.go
model as such..
ANSWER
Answered 2021-Jun-14 at 02:52Scan
places the value into the pointer to a variable you've given it (via &c
), and returns a database transaction object. You're calling that transaction object items
, which it isn't. The items (ie, the contents of your cart) are in c *Cart
, not in the thing returned by Scan
.
Your method modifies c
by filling it, it doesn't have to return anything, unless you want to return the error that Scan
may return.
Instead of this...

I am learning how to control P10 Led matrix 64x32 with NodeModule MCU ESP8266, I google and found this library https://github.com/2dom/PxMatrix and this tutorial https://www.instructables.com/RGB-LED-Matrix-With-an-ESP8266/. I believed that I wire between P10 and ESP8266 in true way in the tutorial, but that P10 led does not display as the example:
The true result will be:
This is my wire diagram:
This is my code:
...ANSWER
Answered 2021-Jun-10 at 09:17I fixed this by adding
display.setPanelsWidth(2);
display.setMuxPattern(SHIFTREG_ABC_BIN_DE);
because my led is combined by 2 matrix 32x16.

I'm expected to get 55912 frames, but I get 3 extra frames. What changes should I make to my code to fix this issue?
The video file is 18fps (00:37:16.12). Maybe its because of that extra 0.60s?
Is there a way to set time limit to 37:16.12 instead of 37:16.60?

-ss time to start the video copy in hh:mm:ss.ms format -t time to copy video, in seconds format (37:16.12 are 2236.12 seconds)
QUESTION
I am trying to gzip all responses. In main.go
...ANSWER
Answered 2021-Jun-07 at 21:501. You should only gzip
when it's requested by the client.
Accept-Encoding: gzip
is never requested, but you gzip
the response anyway.
So curl
gives it back to you as-is.
2. Given the behavior of your browser, it sounds like double-compression. Maybe you have some HTTP reverse proxy in place which already handles compression to the browser, but doesn't compress backend traffic. So you may not need any gzipping at the backend at all - try curl --compressed
to confirm this.
3. You should filter out Content-Length
from the response. Content-Length is the final size of the compressed HTTP response, so the value changes during compression.
4. You should not blindly apply compression to all URI's. Some handlers perform gzipping already (e.g. prometheus /metrics
), and some are pointless to compress (e.g. .png
, .zip
, .gz
). At the very least strip Accept-Encoding: gzip
from the request before passing it down the handler chain, to avoid double-gzipping.
5. Transparent gzipping in Go has been implemented before. A quick search reveals this gist (adjusted for point #4 above):
QUESTION
I'm trying to write a code in vhdl to create a 16 to 1 mux using 2 to 1 mux. I actually thought that to do this we may need 15 two to one multiplexers and by wiring them together and using structural model I wrote the code below. First I wrote a 2 to 1 mux:
...ANSWER
Answered 2021-Jun-06 at 23:54Virtual component binding using component declarations can either be explicit using a configuration specification to supply a binding indication, or rely on a default binding indication.
A default binding indication would rely on finding an entity declared in a reference library whose name matches the component name. That's not the case here, your entity is named MUX_2_1 (case insensitive) while the component name is mux2to1.
It's not illegal to have components unbound in VHDL, it's the equivalent of not loading a component in a particular location in a printed circuit or bread board, it simply produces no output which shows in simulation here as a 'U'.
Here the solutions could be to either change the name of the entity in both the entity declaration and it's architecture from MUX_2_1 to mux2to1, change the component declaration to MUX_2_1 or provide a configuration specification providing an explicit binding indication as a block declarative item in the architecture for mux16to1 of the form
QUESTION
I have run some Python code in Windows 10 and gotten the Traceback error below. Does it mean the string that is supposed to be an int occurs in line 347
of /DeOldify/deoldify/filters.py
or line 1943
of /lib/site-packages/PIL/Image.py
?
For context, below the traceback error, I've also included the steps that lead to this error (I attempted to colorize a black and white film clip based on the DeOldify Colab https://colab.research.google.com/github/jantic/DeOldify/blob/master/VideoColorizerColab.ipynb but only succeeded at colorizing the first frame as a .jpeg) and the full terminal output.
EDIT: Thanks to @Daweo's response, I discovered the problem was with the arguments I entered into the terminal as indicated by "", line 1
. The correct command should have been:
video_path = colorizer.colorize_from_file_name(file_name='my_video.mp4', render_factor=render_factor)
Also, the code for colorizing a photograph is from https://colab.research.google.com/github/jantic/DeOldify/blob/master/ImageColorizerColab.ipynb

QUESTION
I have a restful API utilizing mux and mongo-driver. Following a tutorial, I attempted to setup the server and mongo client like so in the main package:
...ANSWER
Answered 2021-Jun-05 at 21:42The standard way of doing this while avoiding globals would be to define a struct
that represents your server, and its methods would be the handlers. Then the methods share the struct's data, and you place things like your mongo client in there.
Something like this (in your admin
package):

I am deploying an API made using Go and MySQl for the database to Heroku. I am following this guide on it and set up everything but now I am trying to execute a MySQL script to set up the tables with some dummy data. But I am constantly getting errors saying that the script is wrong even though I have used it locally with no issues. I have already connected the MySQL database to the Heroku environment and starting the database throws no errors.
Here are the logs showing the error when deploying it to Heroku:

This returns the URL to the database.
