My calculated HI density fraction from a Galform sub-volume is orders of magnitude too small. What am I missing?

Summary The issue at hand is that the calculated HI density fraction from a Galform sub-volume is orders of magnitude too small. The expected value of average Ω_HI is around 3-5e-4 for z = 0, but the current calculation yields a value of approximately 3e-7. The code provided seems to conserve mass during the gridding … Read more

Latent Class Analysis Using R

Summary The provided R code performs a Latent Class Analysis (LCA) using the poLCA package to identify the optimal number of classes in a given dataset. The code calculates the Bayesian Information Criterion (BIC) for different class models and conducts a Likelihood Ratio Test (LRT) to compare the fit of each model. However, the code … Read more

MatchIt full matching + marginaleffects: cluster-robust SE by subject ID after matching

Summary The question revolves around obtaining cluster-robust standard errors by subject ID after performing generalized full matching using MatchIt and estimating a risk ratio with a weighted Poisson model, followed by computing average comparisons with marginaleffects::avg_comparisons(). The key challenge is determining the correct way to specify clustering in avg_comparisons() to respect the matching structure and … Read more

“Archived non-system classes are disabled because the java.system.class.loader property is specified” – is this a problem?

Summary The warning message “Archived non-system classes are disabled because the java.system.class.loader property is specified” is raised when starting the CLion IDE on a GNU/Linux system. This warning is related to the java.system.class.loader property being set to “com.intellij.util.lang.PathClassLoader”, which disables the use of archived non-system classes. The main concern is whether this is a problem … Read more

How to trigger eSIM installation on Android from Flutter using an activation code (similar to iOS universal link)

Summary The goal is to trigger eSIM installation on Android from a Flutter application using an activation code, similar to how iOS universal links work. Key requirements include opening the native Android eSIM installation flow, passing the activation code automatically, and avoiding native eSIM provisioning logic implementation inside the app. Root Cause The main challenge … Read more

UI authentication issues with solr-nightly:10.1.0

Summary The issue at hand is related to UI authentication with the apache/solr-nightly:10.1.0-SNAPSHOT image in a Docker container. After enabling basic authentication using docker exec -i solr10 bin/solr auth enable -type basicAuth -credentials admin:password, the Solr UI becomes inaccessible, resulting in an HTTP ERROR 401 Authentication failed response. However, the backend API continues to function … Read more
