Remote debugging of python code in Visual Studio Code



Remote debugging with python and visual studio Code


In terminal install debugpy into your environment with something like

    python -m pip install debugpy


Create a visual studio launch configuration and add following to it following (or just use vs code create configuraiton button to easily create it choose type Python and select from the list, 'Remote attach')

{
"name": "Python: Remote Attach",
"type": "python",
"request": "attach",
"port": 5678,
"host": "localhost",
"pathMappings": [{ "localRoot": "${workspaceFolder}", "remoteRoot": "." }]
},

Run this in the command line to start a debugging server with your script runner
python3 -m debugpy --listen 1.2.3.4:5678 --wait-for-client Yourscript.py

Now run the launch configuration from vs code to attach to this debugger

How to write and test Node.JS code that performs mutiple async tasks

This is currently WIP, I will fill in more details but it's a good starting version that is still hopefully useful to the reader... Recently I worked on a project that involved scheduling a number of tasks in parallel in Node.js. Running mutiple tasks I used the await-the library to do this. https://github.com/olono/await-the/blob/master/lib/result.js There are multiple ways to solve this kind of problem. Mainly you have to understand the Node.js is a single threaded environment (See Event loop) and how callbacks operate with a library like async or await-the. Basically, here idea was that you write a function that has a callback as its last argument ```   const doTask = async (arg1, callback) {    const results = await doStuffWith(arg1) ;    callback(results); } ``` Then perform this action on multiple inputs in parallel such as by using the excellent async.mapLimit function if you want to limit how many tasks in parallel you want to to...

Two cool ways to center content in CSS

You may have seen this question, center a div, or whatever, in interviews or other places. I am sure there are other approaches than I am sharing here, but I found these two cool ideas from multiple places (see refs at the end). These are not my original ideas so I will be sure to share where I learned these from:   Using display:flex  Make sure you know how flex works, but to do centering with flex, it's ridiculously simple: div .container { display : flex ; justify-content : center ; /* horizontal alignment */ align-items : center ; /* vertical alignment */ flex-direction : column ; /* since we are doing a vertical column */ padding : 1rem 3rem ; /* not related to centering */ }  Now everything inside <div class="container"> </div> will be centered in both directions! Using display:grid  You are so going to thank for me this one, you are welcome. This one is so simple it does not even need an explanation does it?   div .conta...

How to use function closure to capture common arguments in python

Sometimes you need a function that already 'captures' some information you don't want to repeat when calling it. For example, logging may require you to pass in a lot of contextual information for each call. Instead you can capture the common/unchanging contextual information in a function (using its clsoosure) then call the resulting function with less args (only those that are changing in each call site)   class AClass:   def __init__(self):     self.make_log_msg = lambda m: f"a={self.a}, b={self.b}, message={m}"  def do_something(self):     doStuff();     logger.info(self.make_log_msg('test message')) In the absence of the make_log_msg() function you would need to pass all of a,b,c into every logging function call as in self.make_log_msg(self.a, self.b, message) .  This is possible because make_log_msg returns a function (lambda function in this case) that already captures the values self.a and self.b in its closure at the t...
