huge | Simple user-authentication solution | Authorization library

I'm trying to implement a PHPickerViewController using SwiftUI and The Composable Architecture. (Not that I think that's particularly relevant but it might explain why some of my code is like it is).

I've been playing around with this to try and work it out. I created a little sample Project on GitHub which removes The Composable Architecture and keeps the UI super simple.

It looks like iOS 15 is breaking on both the UIImagePickerViewController and the PHPickerViewController. (Which makes sense as they both use the same UI under the hood).

I guess the nest step is to determine if the same error occurs when using them in a UIKit app.

My code is fairly straight forward. It's pretty much just a reimplementation of the same feature that uses UIImagePickerViewController but I wanted to try with the newer APIs.

My code looks like this...

I ran the following code in RStudio:

I'm developing an API with Spring Boot and currently, I'm thinking about how to handle error messages in an easily internationalizable way. My goals are as follows:

1. Define error messages in resource files/bundles
2. Connect constraint annotation with error messages (e.g., @Length) in a declarative fashion
3. Error messages contain placeholders, such as {min}, that are replaced by the corresponding value from the annotation, if available, e.g., @Length(min = 5, message = msg) would result in something like msg.replace("{min}", annotation.min()).replace("{max}", annotation.max()).
4. The JSON property path is also available as a placeholder and automatically inserted into the error message when a validation error occurs.
5. A solution outside of an error handler is preferred, i.e., when the exceptions arrive in the error handler, they already contain the desired error messages.
6. Error messages from a resource bundle are automatically registered as constants in Java.

Currently, I customized the methodArgumentNotValidHandler of my error handler class to read ObjectErrors from e.getBindingResult().getAllErrors() and then try to extract their arguments and error codes to decide which error message to choose from my resource bundle and format it accordingly. A rough sketch of my code looks as follows:

Input:

I want to apply pagination on a table with huge data. All I want to know a better option than using OFFSET in SQL Server.

Here is my simple query:

I am trying to run a server with a MySQL Database, however I keep getting this huge error and I am not sure why.

There are existing questions asking about labeling a single geom_abline() in ggplot2:

• R ggplot2: Labelling a horizontal line on the y axis with a numeric value
• R ggplot2: Labeling a horizontal line without associating the label with a series
• Add label to abline ggplot2 [duplicate]

None of these get at a use-case where I wanted to add multiple reference lines to a scatter plot, with the intent of allowing easy categorization of points within slope ranges. Here is a reproducible example of the plot:

I am using Ubuntu.
I have recently installed firebase-tools using npm with the command as officially stated:

I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).

Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.

I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.

As far I was trying for example changing all places with hasher->check part like here:

I am trying to encode a small lambda calculus with algebraic datatypes in Scheme. I want it to use lazy evaluation, for which I tried to use the primitives delay and force. However, this has a large negative impact on the performance of evaluation: the execution time on a small test case goes up by a factor of 20x.

While I did not expect laziness to speed up this particular test case, I did not expect a huge slowdown either. My question is thus: What is causing this huge overhead with lazy evaluation, and how can I avoid this problem while still getting lazy evaluation? I would already be happy to get within 2x the execution time of the strict version, but faster is of course always better.

Below are the strict and lazy versions of the test case I used. The test deals with natural numbers in unary notation: it constructs a sequence of 2^24 sucs followed by a zero and then destructs the result again. The lazy version was constructed from the strict version by adding delay and force in appropriate places, and adding let-bindings to avoid forcing an argument more than once. (I also tried a version where zero and suc were strict but other functions were lazy, but this was even slower than the fully lazy version so I omitted it here.)

I compiled both programs using compile-file in Chez Scheme 9.5 and executed the resulting .so files with petite --program. Execution time (user only) for the strict version was 0.578s, while the lazy version takes 11,891s, which is almost exactly 20x slower.
