QUESTION
I am trying to build a huge docker image in an optimized way by applying the principles of incremental building explained here https://www.docker.com/blog/intro-guide-to-dockerfile-best-practices/ .
Unfortunately each time I run the build command docker restarts building the image from scratch, and so I have to download again all the maven dependencies.
Here is the build command:
...ANSWER
Answered 2021-May-16 at 13:03In the documentation it is mentioned that
Each FROM instruction can use a different base, and each of them begins a new stage of the build
To check what steps are cached, run the following command
QUESTION
I am learning React and JavaScript and now I have this CodeSandbox but I can't convert it to JavaScript React I have tried this for the Card
Component:
ANSWER
Answered 2021-Jan-24 at 23:04To swap your Code Sandbox from TypeScript to JavaScript you should just need to:
- Remove all typescript specific syntax from your ".ts" and ".tsx" files (interfaces, typings, etc)
- Change all the file extensions to their JavaScript equivalent i.e. ".ts" -> ".js" and ".tsx" -> ".jsx".
- Update the "main" property of the "package.json" file to point to the renamed entry point. i.e. "src/index.jsx".
I created a quick CodeSandbox with this already done.
QUESTION
Below is some of the data I'm putting into an Azure search index:
I could go with this rigid structure but it needs to support different data types. I could keep adding fields - i.e. Field4, Field5, ... but I wondered if I could have something like a JSON field? So the index could be modelled like below:
...ANSWER
Answered 2021-Jan-25 at 11:10See the article How to model complex data types. The hotel example data translates nicely to your use-case I believe. If your different entities have different sets of properties you can create a "complex type" similar to the Address or Amenities example below.
You can add new sub-fields to a complex field at any time without the need for an index rebuild. For example, adding "ZipCode" to Address or "Amenities" to Rooms is allowed, just like adding a top-level field to an index.

QUESTION
I'm trying to experiment with a HowlerJS playlist code. I would like to make a button that checks if a specific song in the playlist is playing, and if so, hide a line of text when clicked. I'm not very knowledgeable with these things, so I've been shooting in the dark trying to get it working. Is it possible to use this playlist code and make the type of button I need? This is the playlist and the code to hide the line of text:
...ANSWER
Answered 2020-Nov-21 at 22:25Had a look at the Howler player.js code on github and it looks like the player object will expose a playlist
array and an index
property
so you could write a function that checks the playlist to see if a certain track is playing

QUESTION
I have a dataset with two columns: in the first column, the full directory path of a file. In the second column, the date the file was last modified. I am trying to figure out the number of files in each upper level folder ("dog", "feline", "mouse", "anteater") that were last modified later than 2004-06-23. Ultimately, I'd like something like this:
Here's my dataset:

Just wrap it in parentheses and python interpreter is happy about it.
QUESTION
I have been trying to make my enemy spawn every 20 seconds to counteract the fact that the enemy gets stuck underneath platforms when it is directly bellow the player, I have left the method that I was going to use, however I have not had much luck implementing it.
The plan was to use the timer.tick built into python to be able to time every 20 seconds, however I realised that this just worked on the frame rate, as you can see at the top I used start = time.time() to begin the clock, and then write end = time.time() to end the clock after 20 seconds.
...ANSWER
Answered 2018-Oct-21 at 16:42Define start
ahead of the while loop, subtract the current time (now
) from the start time to see if the desired time has passed and then set start
to now
.
QUESTION
How can I rewrite the text cleaning function and make it more efficient?
...ANSWER
Answered 2020-Feb-19 at 21:23It looks like there is not much room for a lot of enhancements. I can recommend to shrunk the first part where you remove links or mentions and the non-letter removal into a single regex, but you need to remove hyphens beforehand then:
