Calling Native Libraries from Java

A couple of options I've used and seen: 

• Java Native interface - watch out for segfaults! 
• Project Panama - early access
• GraalVM - still really new.
• zt-exec - call the native library as an external process
• remotetea - an old favourite if it's legacy C++ code

Google Cloud IAM Madness

After the recent GCP outage related to IAM, I found some odd behaviour with gsutil/gcloud. A script that had faithfully run for many months stopped working with:

ServiceException: 401 Anonymous caller does not have storage.buckets.list access to project xxxx

I tried recreating the service account key used for the operation with no luck. To fix the problem, I had to create a new bucket!

gsutil mb -b on -l us-east1 gs://my-awesome-bucket123ed321/
Creating gs://my-awesome-bucket123ed321/...
gsutil ls
gs://my-awesome-bucket123ed321/
gs://<my_original_bucket_I_couldnt_see>/

Wierd!!!!
