I've been spending the morning searching for viable alternatives for Bitnami's Redis Helm chart.
So far, the best option appears to just do it myself. There are not a lot of great options out there.

A grumpy ItSec guy walks through the office #2
devops0: dude, we've got so many roles in this cluster my terminal buffer runs out when I try to list them all.
devops1: bro, if it works, don't touch.
devops0: sure, but neither I nor anyone else on the project knows who can access what...
ItSec (walking by): just use rbac-tool and review this...
devops1: r... rba... what?
devops0: rbac-tool probably or smth

It's always a good moment to verify who can do what in your Kubernetes cluster.
For basic checks, use native kubectl:
1) Can "I" read secrets?
kubectl auth can-i get secrets
2) To check another identity's permissions (e.g., a ServiceAccount) run:
kubectl auth can-i get secrets --as=system:serviceaccount:somenamespace:someserviceaccount
However, this approach will not work for complex environments. There's a more effective way to do this with rbac-tool [2]. It gives you cluster-wide visibility with simple commands. Check this:
1) Who can do a specific thing? For example: who in the entire cluster can read Secrets?
rbac-tool who-can get secrets
2) Run an RBAC health check - global analysis with risk hints (wildcards in RBAC, overly broad permissions, cross-namespace binds, etc)
rbac-tool analysis
3) Visualize the mess - produce an interactive map of roles, bindings, etc:
rbac-tool visualize
This command writes a report to rbac.html in the current directory.
Alternatives to rbac-tool like rakkess [3] can offer similar "who can" insights, though it may not be actively maintained.
Stay (more) safe!

Utkarsh Kanwat · Why I'm Betting Against AI Agents in 2025 (Despite Building Them)I've built 12+ AI agent systems across development, DevOps, and data operations. Here's why the current hype around autonomous agents is mathematically impossible and what actually works in production.
Messy Drupal deployments are stealing your time.
At Drupal GovCon, Bob McDonald will show you how to take it back.
One GitHub Actions workflow. Any host. No duplicate configs. No endless fixes. Just faster, cleaner deploys so you can focus on the work that matters.
Build smarter. Deploy faster. Sleep better.

So, I'm coming from Fortran mostly, moving to C++, and I've this explicitly vectorized Fortran code which runs column wise operations, e.g.:
a = input(:, 1) + input(:, 2)
Now, I'm wondering how to implement this the fastest using Rcpp/C++.
I can use (Rcpp)Armadillo to implement the implicit logic, or loop through vector elements. Since the overhead of flipping between the two is quite some work I would love someone's take up front.

If you are using raw 'pip install -r requirements.txt' you'll need to switch over to 'source venv/bin/activate && pip install -r requirements.txt' or a similar pattern.

#introduction time. I'm Chopper Dave (pseudonym obviously) and have recently setup this #selfhosted instance.
I work in the IT sector, predominantly as a #sysadmin but dabble in #devops too.
In my free time I work on model kits. Airfix, Tamiya and #warhammer40k mainly. I play a lot of retro games and whittle away the hours working on the #homelab.
I like to post my creations and nature shots from my walks or gardening attempts.
Feel free to follow! Boosts appreciated but not required!
Migrating my last BIND DNS Server (resolver) to PowerDNS today. Already migrated the hidden-master and one of the primaries. Let's hope, that the final one also goes smooth and doesn't cause any issues
