kandi X-RAY | flake Summary
Flake is an HTTP implementation of Twitter's Snowflake written in the Tornado async library. Snowflake is "a network service for generating unique ID numbers at high scale with some simple guarantees." The generated IDs are time plus worker id plus a sequence. Flake will send a 500 response if the system clock goes backwards or if the per millisecond sequence overflows. Usage: ./flake.py --worker_id=WORKER_ID --port=PORT. Where WORKER_ID is a globally unique integer between 0 and 1023. The preferred network setup is to have multiple Flake servers and to connect randomly to one of them. Flake responses should be very quick (<10ms) so its reasonable to setup fallover after a short timeout.

QUESTION
I'm trying to use flake8 only on 3 specific sub directories: features_v2
, rules_v2
and indicators_v2
.
In order to test if my pattern is correct I tried applying it only to features_v2 at first. so I came up with this pattern: exclude = ^(?!.*features_v2).*$
but sadly it doesn't seems to work. Is flake8 does not support lookaround, or it does and I did something wrong?
Is there a better way to use flake on 3 different subdirectories?
...ANSWER
Answered 2022-Apr-11 at 13:50flake8's exclude
is not a regex but a glob -- it cannot support what you're looking for
may I suggest instead to run flake8 on the directories you want?
QUESTION
I'm trying to understand how to implement Threads disputing global variables. In my implementation I created 2 variables and I want 4 Threds (e.g.) to dispute it by decrementing.
The first problem is that the way I implemented to consume will always follow an order (first Thread decrements the flake ice cream and the second Thread decrements the chocolate ice cream).
Is there any way to improve this rule?
And I wouldn't want to know what would be the best place to use CountDownLatch

QUESTION
I'm making an async call to an API and then setting the data I get back to my state variable all inside a useEffect function. Out side of that function I then destructure the values into variables and the render them to the screen.
The issue is that the instructions variable is still undefined at time of render and I'm a bit confused why when the others render fine.
(The instructions variable is also an array of objects)
Top Component
...ANSWER
Answered 2022-Feb-28 at 15:56The useEffect hook is first executed after the first initial render, also the request is asynchronous meaning there will be at least one render before receiving the network response and the data object being populated with the value for instructions.
This is expected behaviour, you can choose to defer rendering part of the component until the data is fetch, or provide some loading state.

I am working with a simple AWS Lambda function :
...ANSWER
Answered 2022-Jan-23 at 06:44Lambda standalone from console
The event
that you get in your lambda function from API, and the one used when you run the function from the console are different. The event
from api passed to your function will have a fixed known format. But when you run the function from console, you are passing the event
in the incorrect format, thus it all breaks.
You have to ensure that your event
structure used when you run the code in console matches the event
structure from the API format.
QUESTION
I am trying to conditonally set the border color of an image. Depending on the image name, I would like to set a different border color.
Here is my code:
...ANSWER
Answered 2022-Feb-12 at 15:51Use a template literal in the string for the border
property so you can use the conditional operator to alternate between the two possibilities.
Define the border in a separate variable beforehand so that it's not unreadable.
You aren't using the index parameter, so feel free to remove it.

QUESTION
Requirement:
I have a class with many fields initialized in __init__
method. Some of these fields should be possible to reset to initial values via a reset()
method.
I would like to provide typing info for these attributes and make Flake, MyPy, PyCharm (and me) happy with the solution.
Possible solutions:
Duplicate initial values
In this solution all tools (MyPy, Flake, PyCharm) are happy but not me. I have initial values in two places (
...__init__
andreset
) and I need to keep them in sync. There is a possibility that if in the future one initial value needs to be modified, then I will not change it in both places.
ANSWER
Answered 2022-Jan-27 at 13:45You could write a custom descriptor that stores the default value and handles the resetting.

I have this beer dataset that I've been trying to clean as a personal project for quite some time, but I can't seem to get past a couple of hiccups.
I have this "list of uneven lists" I guess you would call it, that I need to organize. Here is a brief example of what I'm looking at: [updated to add form of data]
...ANSWER
Answered 2022-Jan-30 at 23:45What you refer to as a "uneven lists" is a "tuple" or a "row". And a set of tuples/rows with the same shape is called a "relation" or a "table".
Where each element is each element is 'weight', 'grain_name', 'ppg', 'deg_litner', 'grain_bill'
In SQL Server you would create tables like
QUESTION
Facebook will randomly take posts I have shared on a company page and make the preview image blank/white. It is maddening.
Here's what I do to replicate:
- Copy URL that I want to share
- Go to Facebook's debug and check URL to confirm a preview image shows
- Go to Facebook and share the URL in a post
- Preview image is blank/white
Example URL: https://hoist.digital/content/blog/know-the-value-of-phone-calls-and-grow-your-business-with-call-tracking
Open graph code in on that URL
...ANSWER
Answered 2022-Jan-06 at 04:33Unfortunately, it is well-known problem on Facebook that has not been fixed for years and there is no canonical answer to your question.
The main problem is URIs using HTTP works just fine and URIs using HTTPS do not. So first of all, you should try to change your og:image:secure
property to og:image:secure_url
, because due to documentation there is no og:image:secure
property.
If it does not help, you can explore this thread and you gonna try different options unless, of course, you have tried it yet.
Please pay attention to such methods:
- Try to add
og:image:url
(yes, it is similar toog:image
but sometimes it can help). - Try to remove
og:image:secure_url
property (yes, it is looking strange, but it is Facebook, and it also might work). - Try to add other og properties such as
og:image:type
,og:image:width
,og:image:height
QUESTION
I have two Nix Flakes: One contains an application, and the other contains a plugin for that application. When I build the application with the plugin, I get the error
...ANSWER
Answered 2022-Jan-04 at 20:29The reason is that the file modules.txt
generated as part of vendoring will contain the nix store path in the replace
directive in this scenario. The vendor
directory is a fixed output derivation and thus must not depend on any other derivations. This is violated by the reference in modules.txt
.
This can only be fixed by copying the plugin's sources into the sources
derivation – that way, the replace
path can be relative and thus references no other nix store path.

Install flake
You can use flake 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.
