QUESTION
e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)
Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka
, that do run with Linux
There is multiple errors, but this is the first one thrown
...ANSWER
Answered 2021-Dec-09 at 15:51Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391
You need to wait until Apache Kafka 3.0.1
or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

QUESTION
I am experimenting with ZK framework and look for ways to load a zul-defined view programmatically via a utility class that uses Executions to load a view definition programmatically.
I do however fail to find a way to set the view model class programmatically, which would be very convenient and would allow some very simple way of reusing a view with different view model classes.
I.e. the code to load the view looks like this:
...ANSWER
Answered 2022-Mar-14 at 06:19Just to make sure I've understood:
- You have some zul fragment (such as a reusable UI structure)
- This fragment uses the MVVM pattern, but you want to choose a viewModel object when you are instantiating that fragment, instead of declaring a class name in the zul viewModel="@id()@init()" attribute
- You want to initialize that fragment from a java class that has access to the UI (using Execution#createComponents to load the fragment and attach them to the page)
Does that sound correct?
If that's the case, you can make this way simpler
The attribute can be written as viewModel="@id('yourVmId')@init(aReferenceToAnAlreadyInstantiatedObject)"
.
Important note here: Notice that I have NOT put quotes around the object in the @init declaration. I'm passing an actual object, not a string containing a reference to a class to be instantiated.
When you invoke execution.createComponents() you may pass a map of arguments to the created page. You can then use the name of the relevant passed object when you create bind the VM.
have a look at this fiddle (bit rough, but it should make sense): https://zkfiddle.org/sample/2jij246/4-Passing-an-object-through-createComponents-as-VM#source-2

QUESTION
I am trying to show native ads in Flutter.
https://codelabs.developers.google.com/codelabs/admob-inline-ads-in-flutter
https://github.com/googlecodelabs/admob-inline-ads-in-flutter
I used this codelab but they are showing small native ads.
In fact, I successfully implemented their codelab in my Flutter project.
But I want to make size medium, not small.
https://developers.google.com/admob/ios/native/templates
GADTSmallTemplateView(It seems this one, I don't want like small size)
GADTMediumTemplateView(My aim is to make my native ads like this one)
What is height in the codelab?
...ANSWER
Answered 2022-Mar-08 at 16:21I summed height of all elements in the design. It was 308. Then, I think 310 will be an ideal number. No problem, when I make it 310. Everything seems good.
QUESTION
I have been using the database of lmfdb.org to know the integral basis of a number field. Now, I want to utilize Pari GP in multiplying algebraic integers. However, I have encountered a problem. Pari GP uses the integral basis "nf.zk" in its computations, which apparently is not always the same as the "nfbasis(f)", which is the integral basis that lmfdb.org provides.
For example, we have the following code from Pari GP.
...ANSWER
Answered 2022-Mar-06 at 23:12When we take the trouble to initialize an
nf
structure withnfinit
, we perform precomputations to speed up later work. Here,nfinit
first computes the integer basis by callingnfbasis
, which returns the (canonical) HNF basis, then LLL-reduces it with respect to the T2 norm. The LLL-reduced basis is usually different from the HNF one, but it usually have smaller elements.This LLL reduction can be expensive (in particular when the degree is large) but it ensures that time complexities are bounded in terms of the field discriminant instead of the size of the input polynomial. I believe all polynomials defining number fields in the lmfdb were run through
polredabs
which ensures their coefficients are small (in terms of the field discriminant), but the HNF integer basis may still be much larger than the LLL one. Additionally, if an algebraic integer has small T2 norm, its expression in terms of the LLL-reduced basis is guaranteed to have small coefficients, whereas it can have much larger coefficients on the HNF basis.In pari-2.14 (which is not released yet but available via
git
or through nightly snapshots on the PARI/GP website), you can use nfinit(, 4), which removes the LLL reduction step. This speeds up the initialization, but usually slows down every operation involving the resultingnf
.

I am considering using ClickHouse keeper to replace zookeeper for data replication. And zookeeper has lots of useful metrics for monitoring/convenient triage. I checked ClickHouse documents and CurrentMetrics/ProfileEvents files but found no similar monitoring data to zk(https://zookeeper.apache.org/doc/r3.7.0/zookeeperMonitor.html). Pls. direct me to the right way, thanks!

QUESTION
I try to figure out forEach attribute in Zk framework. Here is the definition of the forEach:
This attribute is used in conjunction with collections. For each element in the collection, the element is rendered with the concrete value. Example:
{listitem label="${each}" forEach="${elements}" /}
I have a zul page that tries to populate listitem:
...ANSWER
Answered 2022-Jan-19 at 07:35It looks like you are trying to use the forEach attribute. While it's a possible choice, I'd recommend against it because it's an older (and less wieldy) iteration option in ZK.
Your option are: ZUTI - forEach element (require ZK EE)
This is the easiest an most straightforward iterative template option. Collection and template goes in, templated result goes out.

Install zk
You can use zk like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
