kandi X-RAY | PID Summary

PID is a C library. PID has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

PID controller implementation written in C. Note on 'derivative-on-measurement': Since the 'error signal' effectively going into the differentiator does not depend on the setpoint: e[n] = 0 - measurement, and therefore (e[n] - e[n - 1]) = (0 - measurement) - (0 - prevMeasurement) = -Kd * (measurement - prevMeasurement). (Note the minus sign compared to derivative-on-error!) I've included the minus sign in the code, so gains will have the effect as normal.

psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory

Asked 2022-Apr-04 at 15:46

Not really sure what caused this but most likely exiting the terminal while my rails server which was connected to PostgreSQL database was closed (not a good practice I know but lesson learned!)

I've already tried the following:

Rebooting my machine (using MBA M1 2020)
Restarting PostgreSQL using homebrew brew services restart postgresql
Re-installing PostgreSQL using Homebrew
Updating PostgreSQL using Homebrew
I also tried following this link but when I run cd Library/Application\ Support/Postgres terminal tells me Postgres folder doesn't exist, so I'm kind of lost already. Although I have a feeling that deleting postmaster.pid would really fix my issue. Any help would be appreciated!

My original answer only included the troubleshooting steps below, and a workaround. I now decided to properly fix it via brute force by removing all clusters and reinstalling, since I didn't have any data there to keep. It was something along these lines, on my Ubuntu 21.04 system:

Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'

Asked 2022-Mar-25 at 06:14

I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

I figured out that these lines in our build.gradle file are the origin of the problem.

ANSWER

Answered 2022-Feb-08 at 12:36

This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

There are two issues here:

Oracle Database is not supported on ARM processors, only Intel. See here: https://github.com/oracle/docker-images/issues/1814
Oracle Database Docker images are only supported with Oracle Linux 7 or Red Hat Enterprise Linux 7 as the host OS. See here: https://github.com/oracle/docker-images/tree/main/OracleDatabase/SingleInstance

Oracle Database ... is supported for Oracle Linux 7 and Red Hat Enterprise Linux (RHEL) 7. For more details please see My Oracle Support note: Oracle Support for Database Running on Docker (Doc ID 2216342.1)

The referenced My Oracle Support Doc ID goes on to say that the database binaries in their Docker image are built specifically for Oracle Linux hosts, and will also work on Red Hat. That's it.

Because Docker provides process level virtualization it still pulls kernel and other OS libraries from the underlying host OS. A Docker image built for Oracle Linux needs an Oracle Linux host; it doesn't bring the Oracle Linux OS with it. Only Oracle Linux or Red Hat Linux are supported for any Oracle database Linux installation, with or without Docker. Ubuntu, Mac OS, Debian, or any other *NIX flavor will not provide predictable reliable results, even if it is hacked into working or the processes appear to work normally.

Possible solution

Upgrade google analytics to firebase analaytics. Hope it'll solve your problems.Also upgrade all the library what're you using.

For me below solutions solve the problem.

Add PendingIntent.FLAG_IMMUTABLE to your pending intents.

Here is an example -

PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);

iOS app crashes at launch on Testflight for iOS 14 and below but not iOS 15+

Asked 2022-Feb-07 at 22:16

We're having some strange issue with our app and/or Testflight since a few days ago: our app runs fine on simulator and devices (iOS 12, iOS 14 & iOS 15) when run from Xcode, but it crashed at launch when we archive and distribute it via Testflight for iOS 14 and below, but NOT for iOS 15 (we haven't tried to actually release to the AppStore). The app was working perfectly fine on iOS 12+ until then, on Testflight or otherwise. No crash log is ever generated by these crashes (either on Crashlytics, or Organizer, or even in the device crash logs), and what's more mysterious is that when re-archiving past versions of the code that had no issues 3 weeks ago and are live on the app store, we are now getting the crashes.

Uvicorn async workers are still working synchronously

Asked 2022-Feb-07 at 18:39

Question in short

I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

Question in detail

This is what I did so far in my local environment:

When running the gunicorn command, you can try to add workers parameter with using options -w or --workers.

It defaults to 1 as stated in the gunicorn documentation. You may want to try to increase that value.
