Answered 2021-Dec-18 at 02:01WebGL is a cross-platform, open web standard for a low-level 3D graphics API based on OpenGL ES, exposed to ECMAScript via the HTML5 Canvas element. WebGL at it's core is a Shader-based API using GLSL, with constructs that are semantically similar to those of the underlying OpenGL ES API. It follows the OpenGL ES specification, with some exceptions for the out of memory-managed languages such as JavaScript. WebGL 1.0 exposes the OpenGL ES 2.0 feature set; WebGL 2.0 exposes the OpenGL ES 3.0 API.
Now, with the availability of Selenium Stealth building of Undetectable Scraper using Selenium driven ChromeDriver initiated google-chrome Browsing Context have become much more easier.

Answered 2022-Mar-16 at 08:10If your image has a latest
tag, the Pod's ImagePullPolicy
will be automatically set to Always
. Each time the pod is created, Kubernetes tries to pull the newest image.
Try not tagging the image as latest
or manually setting the Pod's ImagePullPolicy
to Never

If you're using static manifest to create a Pod, the setting will be like the following:
QUESTION
Hi guys I'm using jsoup in a java webapplication on IntelliJ. I'm trying to scrape data of port call events from a shiptracking website and store the data in a mySQL database.
The data for the events is organised in divs with the class name table-group and the values are in another div with the class name table-row.
My problem is the divs rows for all the vessel are all the same class name and im trying to loop through each row and push the data to a database. So far i have managed to create a java class to scrape the first row.
How can i loop through each row and store those values to my database. Should i create an array list to store the values?
this is my scraper class
ANSWER
Answered 2022-Feb-15 at 17:19You can start with looping over the table's rows: the selector for the table is .cs-table
so you can get the table with Element table = doc.select(".cs-table").first();
. Next you can get the table's rows with the selector div.table-row
- Elements rows = doc.select("div.table-row");
now you can loop over all the rows and extract the data from each row. The code should look like:

QUESTION
I am trying to get my deployment to only deploy replicas to nodes that aren't running rabbitmq (this is working) and also doesn't already have the pod I am deploying (not working).
I can't seem to get this to work. For example, if I have 3 nodes (2 with label of app.kubernetes.io/part-of=rabbitmq) then all 2 replicas get deployed to the remaining node. It is like the deployments aren't taking into account their own pods it creates in determining anti-affinity. My desired state is for it to only deploy 1 pod and the other one should not get scheduled.
...ANSWER
Answered 2022-Jan-01 at 12:50I think Thats because of the matchExpressions
part of your manifest , where it requires pods need to have both the labels app.kubernetes.io/part-of: rabbitmq
and app: testscraper
to satisfy the antiaffinity rule.
Based on deployment yaml you have provided , these pods will have only app: testscraper
but NOT pp.kubernetes.io/part-of: rabbitmq
hence both the replicas are getting scheduled on same node
from Documentation (The requirements are ANDed.):

...ANSWER
Answered 2021-Dec-24 at 12:11Check your Classpath: you must have the Jar containing com.crealytics.spark.excel in it.
With Spark, the architecture is a bit different than traditional applications. You may need to have the Jar at different location: in your application, at the master level, and/or worker level. Ingestion (what you’re doing) is done by the worker, so make sure they have this Jar in their classpath.
