kandi X-RAY | b2ac Summary

b2ac is a Python library typically used in Utilities, Math applications. b2ac has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Python and C implementations of an ellipse fitting algorithm in double and fixed point precision. The implementations here were never meant for production, but were written as an examination of how much speedup could be attained from implementing ellipse fitting methods in fixed point and at what precision cost. The ellipse fitting method in [2] (an improved version of the one in [1]) was implemented.

I am trying to run sonar swift. I have already sonarQube with the plugin and I can access it locally using this url http://localhost:9000 . I have installed all prerequisites that you can find here :

But I can't figure out what is this error when i launch run-sonar-swift.sh.

If anyone can bring me the light I would be very grateful.

Here the logs when I run in terminal command ./run-sonar-swift.sh -v :

ANSWER

Answered 2018-May-15 at 17:13

It seems that error was due to provisioning profile. When I added my Provisioning Profile and try it again the problem was resolved. 
Then I had another problem with MessageKit:“Segmentation fault: 11” It was a CocoaPods Podfile config issue. So I had to switch compilation mode for Debug from "Single File" to "Whole Module” by click on Pods in Xcode project navigator then select MessageKit in targets of pods then Builds settings tab then in searcher tap ‘compilation mode’ and switch “Single File” to “Whole Module” and re-run script run-sonar-swift.sh

⚠️ each time you make a pod install / update or something that can change pods you have to switch compilation mode for Debug from "Single File" to "Whole Module” for the pod which give you an error when you launch run-sonar.swift.sh with -v for verbose. 

After that it was not yet the end of my problems! In fact I had a last problem which was an error with SwipeCellKit pod: “No such module SwipeCellKit”. To resolve this problem follow instructions given here https://stackoverflow.com/a/37732248/6188918
Then I tried again and the rest of the script started (SwiftLint, Tailor & Lizard) and I thought this time it was finally good but an error occurred once again a new error message at the end of the script concerning Lizard which was:

ERROR: Error during SonarQube Scanner execution

ERROR: File MyprojectName/Domains/Repositories/Local/cacheManager.swift can't be indexed twice. Please check that inclusion/exclusion patterns produce disjoint sets for main and test files

ERROR: Re-run SonarQube Scanner using the -X switch to enable full debug logging.

To resolve this inclusion/exclusion I followed the answer given here: https://stackoverflow.com/a/40150551/6188918 by adding these to line in sonar-project.properties file below sonar.swift.excludedPathsFromCoverage line:

sonar.test.inclusions=**/*Test*/**

sonar.exclusions=**/*Test*/**

I tried again but with parameter -notailor(run script and skip Tailor):

./run-sonar-swift.sh -notailor -v

just to save a little time because tailor take time

And after launch the script... Boom a new error... But it was a known issue:

Error: Caused by: org.sonar.api.measures.PersistenceMode

And the issue is explained here https://github.com/Backelite/sonar-swift/issues/118

So I downloaded this .jar file “backelite-sonar-swift-plugin-0.4-sonar-7-quick-fix.jar” found here https://github.com/Hugal31/sonar-swift/releases/tag/0.4-sonar-7-quick-fix and replace it in plugins of my local SonarQube and try again.

…and this time after an umpteenth launch I finally saw the light

Hope this answer will help and if you have a question don’t hesitate.   Good luck & have fun :)

PS: You’ll find here some options to run script with parameters:

./run-sonar-swift.sh -noswiftlint -v (run script with verbose option and skip SwiftLint)

./run-sonar-swift.sh -notailor -v (run script with verbose option and skip Tailor)

./run-sonar-swift.sh -nounittests -v (if your project does not have scheme configured to be tested launch with this parameter)

If you want more info check in run-sonar-swift.sh script and check around lines 125 ## COMMAND LINE OPTIONS

PS2: I have also opened an issue in sonar-swift GitHub if it can help: https://github.com/Backelite/sonar-swift/issues/138

Rails NoMethodError for Blog#create on Heroku, but not Localhost

ANSWER

Answered 2018-Jul-17 at 17:12

From the logs and the fact it's working fine on your localhost, it's probably an error to host your tmp image file.

You should take a look at these articles:

Edit:

I just saw you get the same error without an image, but don't you set any default image ?

-> Could you post error logs without uploaded image ?

Edit2:

I went on your website, I updated an image on an existing blog post and it works so it's probably not linked to the image system.

Edit3:

After some tests on your websites, it's the tag_list field which is wrong: you can create some new blog post without tags but as soon as you insert some tags an error is raised.

Ps: Sorry I did not managed to get my tests deleted without routes

How to UNNest multiple arrays in BigQuery?

Asked 2018-Jun-01 at 04:55

I have this json that is stored in a BigQuery table in 3 fields token, questions, answers

token:STRING, questions:STRING, answers:STRING

Questions and answers are STRING because they are dynamic fields.

token field has single value.

questions field has dictionary object with "fields" being list object and has 3 questions.

answers field is a list object with answers to the 3 questions and id will be used for matching a question to an answer. Below is the JSON download from bigquery

Below example is for BigQuery Standard SQL and makes some assumption about your data in terms of how those json strings are formatted - so it most will likely require some tuning for regexp's. But it works with below dummy data

Save image from http response with sockets in C and Lua

Asked 2017-Feb-27 at 02:50

I made a C function that sends a http request over https and now I need to grab the image retrieved with that request with Lua. But when I remove the header and save the body the image is not a valid one.

When the file requested is text nothing wrong happens.

This is the function to send the http request

ANSWER

Answered 2017-Feb-27 at 02:50

Finally!

The reason I was getting garbage after the header was because I was using functions for NULL terminated strings on the image data (I guess that's why text responses were display just fine).

Instead of using strncat I made a concatenation function that uses a fixed size to concatenate the strings.

As you have changed the OutputPath to $(Build.BinariesDirectory)\$(BuildPlatform)\$(BuildConfiguration), so you also need to specify the test assembly in VS test task to: $(Build.BinariesDirectory)\$(BuildPlatform)\$(BuildConfiguration)\*test*.dll:
