QUESTION

What does the "-" mean in front of a ruby symbol?

Asked 2022-Mar-21 at 11:50

When I had a look into the ActiveRecord source today, I stumbled upon these lines

name = -name.to_s

https://github.com/rails/rails/blob/2459c20afb508c987347f52148210d874a9af4fa/activerecord/lib/active_record/reflection.rb#L24

and

ar.aggregate_reflections = ar.aggregate_reflections.merge(-name.to_s => reflection)

https://github.com/rails/rails/blob/2459c20afb508c987347f52148210d874a9af4fa/activerecord/lib/active_record/reflection.rb#L29

What purpose does the - operator serve for on the symbol name?

ANSWER

Answered 2022-Mar-21 at 11:05

That's String#-@:

Returns a frozen, possibly pre-existing copy of the string.

Example:

a = "foo"
b = "foo"

a.object_id #=> 6980
b.object_id #=> 7000

vs:

a = -"foo"
b = -"foo"

a.object_id #=> 6980
b.object_id #=> 6980

QUESTION

How to convert lidar format las to data.frame?

Asked 2022-Mar-19 at 17:07

Lidar data is simply 3d coordinates, usually in las file format. Сontent example

library(rgdal)
library(raster)
library(tmap)
library(tmaptools)
library(lidR)
library(RStoolbox)
las_cat <- readLAScatalog("C:/1/078-638.las")
summary(las_cat)
opt_chunk_size(las_cat) <- 500
plot(las_cat, chunk_pattern = TRUE)
las_cat
#> class       : LAScatalog (v1.2 format 1)
#> extent      : 637999, 638240.5, 6077999, 6079999 (xmin, xmax, ymin, ymax)
#> coord. ref. : NA 
#> area        : 483081.1 units²
#> points      : 3.68 million points
#> density     : 7.6 points/units²
#> density      : 5.6 pulses/units²
#> num. files  : 1

Is there a way to get point coordinates in a typical data.frame for R? As an example we can use data from this http://data.wvgis.wvu.edu/elevation/. Also, is there a way to get the angle of reflection, the number of reflections in the data.frame from the lidar file?

ANSWER

Answered 2022-Mar-19 at 08:58

Please find below one possible solution to get a data.table,data.frame with all the information. You can use as.data.frame() to get a pure data.frame but a data.table is a data.frame

Reprex

NB: I used a .las dataset built in the lidR library as it is more convenient.

The example dataset from lidR

library(lidR)

LASfile <- system.file("extdata", "example.laz", package="rlas")
las <- readLAS(LASfile)

QUESTION

nexus-staging-maven-plugin: maven deploy failed: An API incompatibility was encountered while executing

Asked 2022-Feb-11 at 22:39

This worked fine for me be building under Java 8. Now under Java 17.01 I get this when I do mvn deploy.

mvn install works fine. I tried 3.6.3 and 3.8.4 and updated (I think) all my plugins to the newest versions.

Any ideas?

Update: Version 1.6.9 has been released and should fix this issue! 🎉

This is actually a known bug, which is now open for quite a while: OSSRH-66257. There are two known workarounds:

1. Open Modules

As a workaround, use --add-opens to give the library causing the problem access to the required classes:

export MAVEN_OPTS="--add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.text=ALL-UNNAMED --add-opens=java.desktop/java.awt.font=ALL-UNNAMED"
mvn deploy

2. Manage Upstream Dependencies

Or you can update the library that causes the problem:

<plugin>
  <groupId>org.sonatype.plugins</groupId>
  <artifactId>nexus-staging-maven-plugin</artifactId>
  <version>1.6.8</version>
  <extensions>true</extensions>
  <configuration>
    <serverId>ossrh</serverId>
    <nexusUrl>https://s01.oss.sonatype.org/</nexusUrl>
    <autoReleaseAfterClose>true</autoReleaseAfterClose>
  </configuration>

QUESTION

Get passed Annotation Parameters from Field Annotations

Asked 2022-Jan-20 at 21:05

I have two annotations, this class one:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface Processor {
  public String description() default "";
}

And also this Field one:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface ProcessorParameter {
    public String name() default "";
    public String value() default "";
    public String[] range() default {};
    public String description() default "";
}

They both are getting used in a class like this one:

    @Processor(description = "blabla")
    public class Prozessor1{
        @ProcessorParameter(description = "test3")
        public int parameter1;
        @ProcessorParameter(description = "test4")
        public int parameter2;
        @ProcessorParameter(description = "test5")
        public int parameter3;
    }

I have different classes of the Prozessor and I want to be able to access all the parameters of the Prozessor and ProcessorParameter Annotation.

Right now I am using this code:

public static void main(String[] args) {
        Reflections ref = new Reflections();
        for (Class<?> cl:
                ref.getTypesAnnotatedWith(Processor.class)){
            Processor processor = cl.getAnnotation(Processor.class);
            System.out.printf("Found class: %s, with meta name: %s%n",
                    cl.getSimpleName(),processor.description());
            for(Field field : cl.getFields()) {
                System.out.printf("Found parameter: %s and %s%n",
                        field.getName(), field.getName());
            }
        }
    }

Right now I am getting this as a result:

Found class: Prozessor1, with meta name: blabla
Found parameter: parameter1 and parameter1
Found parameter: parameter2 and parameter2
Found parameter: parameter3 and parameter3

I obviously do not need the second field.getName() but I want to access the passed ProcessorParameter description ("test3"/"test4"/"test5") but I do not know how to access this.

ANSWER

Answered 2022-Jan-20 at 21:05

To access the @ProcessorParameter annotation you just need to invoke this method getAnnotation(Class<T> annotationClass) on the field object inside the second loop:

for(Field field : cl.getFields()) {
    ProcessorParameter param = field.getAnnotation(ProcessorParameter.class);
}

NOTE: This call would actually return null in case the given annotation is not present on the field

QUESTION

No cubemap ("material.envMap") reflection on polygon faces with orthographic cam

Asked 2022-Jan-05 at 01:54

Why won't a MeshPhongMaterial's envMap property work on polygonal faces when viewed through an orthographic camera?

It works on spheres but not an IcosahedronGeometry, for example. If I set the detail parameter of the IcosahedronGeometry to 2+ (more faces), the envMap begins to show. But if I switch to perspective cam, the envMap is fully visible even with detail of 0.

This is what it looks like with perspective cam, note the cubemap reflection of some clouds:

This is what it looks like with orthogonal cam and detail is 0, note the lack of cubemap reflection (please ignore the warping of the image):

Orthogonal cam, detail is 1; cubemap reflection is back:

The only difference between these two versions of the script is the camera.

Here's the code I'm using to create this object:

import uvGridImg from './img/grid.png';
import nxImg from './img/nx_50.png';
import pxImg from './img/px_50.png';
import nyImg from './img/ny_50.png';
import pyImg from './img/py_50.png';
import nzImg from './img/nz_50.png';
import pzImg from './img/pz_50.png';

const envTexture = new THREE.CubeTextureLoader().load([
    pxImg, //right
    nxImg, //left
    pyImg, //top
    nyImg, //bottom
    pzImg, //back
    nzImg, //front
])
envTexture.mapping = THREE.CubeReflectionMapping
const texture = new THREE.TextureLoader().load(uvGridImg)
const icosahedronGeometry = new THREE.IcosahedronGeometry(1, 0)
const material = new THREE.MeshPhongMaterial()
material.map = texture;
material.envMap = envTexture;

///An attempt to explicitly set every potentially relevant property...

material.envMapIntensity = 0.0;
material.transparent = false;
material.opacity = 1.0;
material.depthTest = true;
material.depthWrite = true;
material.alphaTest = 0.0;
material.visible = true;
material.side = THREE.FrontSide;
material.flatShading=true;
material.roughness = 0.0;
material.color.setHex(0xffffff);
material.emissive.setHex(0x0);
material.specular.setHex(0xffffff);
material.shininess = 30.0;
material.wireframe = false;
material.flatShading = false;
material.combine = THREE.MultiplyOperation;
material.reflectivity = 1.0;
material.refractionRatio = 1.0;
const icosahedron = new THREE.Mesh(icosahedronGeometry, material)
icosahedron.position.x = 0
scene.add(icosahedron);

For an MVCE, please see the example from this tutorial (you will have to add your own orthographic cam to compare with the given perspective cam). Here are image files for the textures.

UPDATE It seems like all non-spherical geometries cannot render a cubemap reflection correctly thru an orthographic cam. The plane, cylinder, box geometries all fail to render a environment map reflection beyond painting the entire face one uniform reflective color. The sphere, lathe, *hedron geometries (at high levels of detail) will render cubemap reflections.

Is there any way around this? This seems like a huge limitation while working with orthographic cameras.

ANSWER

Answered 2022-Jan-05 at 01:54

This is the expected behavior.

With perspective cameras, the reflective "rays" separate as they get further away from the camera, reflecting a wider angle of the envMap.
With an ortho camera these reflective "rays" do not separate because they're parallel. So the reflection on a flat face is a very narrow angle of the envMap.

See this demo I quickly put together to demonstrate what you're seeing:

It seems to work on spheres because when the parallel orthographic "rays" bounce off a rounded surface, these rays grow wider apart. They are no longer parallel (as is the case with a Perspective camera).

You can see the reflections still work on your demo because the faces alternate between light and dark as you rotate them. You're just looking at a much narrower segment of the envMap:

Unable to find out where reflections-maven plugin comes from

Asked 2022-Jan-02 at 13:34

There executes a particular Maven plugin and I struggle to find out where it comes from to either remove or replace it as its compile dependency link is broken. I am talking about org.reflections:reflections-maven:0.9.8 that depends on org.jfrog.jade.plugins.common:jade-plugin-common:1.3.8 which Maven is not able to download from the central repository as the link redirects to OpenMind location and results in 404 (link).

Instead of including such JAR in the project structure, I would rather figure out where is reflections-maven plugin defined as this plugin is discontinued (GitHub) but somehow is executed during the build (mvn clean install).

[INFO] --- reflections-maven:0.9.5:reflections (default) @ my-module ---
[INFO] Reflections took 240 ms to scan 1 urls, producing 35 keys and 128 values 
[INFO] Reflections successfully saved in C:\Dev\my-project\my-parent\my-module\target\classes\META-INF\reflections\my-module-reflections.xml using XmlSerializer

I haven't found where is reflections-maven defined in any of the multi-module project structure or used. Note I use Maven 3.3.9. My attempts:

Skimming through all plugins and dependencies pom.xml of the failing module and all its parents (the module depends on other modules, however, they were all built successfully before the failing one).
mvn dependency:tree -Dverbose doesn't mention any of reflections-maven or jade-plugin-common at all. The command generates over 136k lines, so it was required to save the output into a file and perform the full-text-search. I am afras Maven 3 is the limit here as far as I understand from this comment.
Using depgraph-maven-plugin gave me the very same negative result.
mvn dependency:analyze -DignoreNonCompile gives only an information that the artifacts were resolved and that where it ends. it doesn't really show anything useful.

Checking the artifacts using the reflections-maven from here, however, none of the artifacts mentioned appear in my project as well.

Question: If I don't have such JAR in the local repository, the build fails as the plugin is executed. In that case, how can I find a way any plugin (particularly reflections-maven in my case) is truly imported and executed in the project?

Feel free to ask for more info in the commens. I use IntelliJ Idea, Maven 3.3.9 and Java 7 if it matters.

Solution 1 (didn't work for me): I have tried to run mvn -Dverbose=true -Doutput=./effective-pom.xml help:effective-pom and both the normal and the verbose form of effective-pom displays the same output of reflections-maven plugin with no additional information about its origin. Since the file is rather big, I include a screenshot:

This might be an issue with my Maven 3.3.9 with a custom settings.xml and a specific IntelliJ Idea. I assume the verbose output would lead to the true origin.

Solution 2:

Upon installing Netbeans (I use IntelliJ Idea by default), the Effective tab of the POM editor finally led me to the true origin where the plugin is defined.

Sadly, IntelliJ Idea doesn't provide such navigation through its effective POM and navigating to the origin is virtually impossible without manual clicking through parent POMs.

With Help:Effective-Pom:

mvn -Dverbose=true -Doutput=./effective-pom.xml help:effective-pom

We can analyze our "effective pom" (Pom#inheritance, Pom#super-Pom).

The verbose flag will also add the source pom (artifact) as a comment to each output line.
output sets an output file. (default: prints to console)

"inter alia" it allows us to locate/override any inherited plugin/dependency/"pom element".

Unfortunately the output generates:

for "trivial" projects "hundreds" lines of pom.
for "non-trivial" (spring-boot-starter), it gets easily into "ten-thousands" (lines of pom).

In intellij we have a "Show effective Pom" command, which basically invokes the mentioned goal and shows the output (in community edition unfortunately!?) without "verbose".

netbeans has a "Effective" tab in its "Pom Editor":

scrolling/cursoring is here also "cumbersome", but we have "full":
"Navigation" (window) support
Text search
Code hints, etc...

(, "Graph" view also very nice...(and unique feature among "maven IDES (that i know)", and it can be installed un-rooted;)!

Update:

So the mojo seems to work as documented:

<verbose> boolean (since:)3.2.0 Output POM input location as comments.

Default value is: false.

User property is: verbose.

For verbose to have an effect, we need to:

<project ...>
 ...
 <build>
   <plugins>
     <artifactId>maven-help-plugin</artifactId>
     <version>3.2.0</version> <!-- or higher! -->
   </plugins>
 </build>
 ...
</project>

... respectively can (without pom modification):

mvn -Dverbose=true -Doutput=./eff.pom.xml \
  org.apache.maven.plugins:maven-help-plugin:3.2.0:effective-pom

Getting below error

ERROR [Worker clientId=connect-1, groupId=compose-connect-group] Uncaught exception in herder work thread, exiting:  (org.apache.kafka.connect.runtime.distributed.DistributedHerder) org.apache.kafka.common.errors.TimeoutException: Timeout of 60000ms expired before the position for partition <KAFKA_CONNECT_OCI_ID>-offset-0 could be determined
INFO Kafka Connect stopping (org.apache.kafka.connect.runtime.Connect)

I don't think there are network issues, Because when I have different topic name or wrong bootstrap server then I get different error, not even starts up. But for me this error gets after a min, mean time REST calls for GET requests work.

Please note that similar config for AWS MSK works for me.

Please help me to resolve the issue.

UPDATE: OCI streaming service doesn't support latest version of Kafka connect. It worked after I changed to 5.x

Install reflections

You can download it from GitHub, Maven.
You can use reflections like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the reflections component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
