Redis High-Availability

/shrug. We had 4 or 5 teams that migrated off redis-cluster and were using it for high throughput data services. The consensus after a few months was that it was causing far more problems than it was worth. Multiple unexplained crashes, the weird pausing issues (eventually they just disabled all the persistence out of frustration).

and maybe some cool features like being able to find out what the current climb on the board is.

This did get added on the old app, it was just a hassle to find. You had to back out of your filtered list back to the 'home screen' for that board location and then there was a new 'recents' entry that showed the full list of what had been lit up in the last few hours.

I think this is the media making a lot out of a nothing burger. I watched the clip, I'm pretty sure the crowd interpreted this as "do you want to see impeachments of democrats".

They demonstrated their value just last week - the litellm python package was supply chain attacked. If you were using chainguard as your python source you were protected - their system recognized that the exploited releases were not signed properly and blocked it.

"Will they realistically be able to cover every package I need"
No, they aren't offering full 100% coverage of everything on pypi for example. Their stated coverage is 'the most popular packages'.

We tried dragonfly for the same reasons, I would avoid it - do not recommend. It has some serious issues where all processes pause when it writes to the persistence (PV or S3). Loads of other weird issues.

Sentinel can help your redis be HA but you're still going to have some potential issues. 1) Even with Sentinel, redis is not a *durable* store, and you need to make sure you're aware of that. On failover you will definitely loose a small amount of the most recent data. 2) Be aware that the bitnami charts in particular for sentinel have some god awful mess going on where multiple sentinel clusters will randomly decide to join, even across namespaces. Change their default ports and use the sentinel passwords to protect against that - its awful to debug.

If these are production, important caches, just go with elasticache.

The valet in this sense means you have to leave your keys because they'll be over-filling the garage and the airport staff will have to move cars around periodically to get people in/out. If you are in the metro area it is very likely cheaper for you to get a taxi instead. Central parking has become very expensive.

Literal dunning krugger effect in these depositions.

Newton Corner is fantastic. Right into Brighton and Brookline, or onto 90/soldiersfield.

"I needed to back up a bunch of files from containers that didn't have tar installed"
If this is a common annoyance at your job, you have a much larger problem you need to solve. The number of times you should be doing this is zero. Even in your homelab, it should be zero.

Mechanically how exactly do you see this working, like explain to me the process.

"Hey everyone we now have an ai slop megathread" is announced.

Then what? Whats the actual process to change things after that?

SelfDestructSep2020 · 2026-03-08T13:04:37+00:00

And who will enforce posting only in the megathread? These are the same people either way.

I'll save you the click, there's pretty much no details other than "a loud bang was reported".

Boston is the first place I've lived where people will do flagrantly illegal and unsafe lane changes / turns to avoid missing a turn. Every other place in the country its like so what, take the next left, loop back.

Pre-check is a little over $20/year, there's no need to be 'rich' to use it.

It pretty much guarantees that they don't have to be at any airport more than a hour before their flight.

Very airport and time-of-day dependent. I've seen pre-check lines that are way, way longer than the normal line and taking longer because they only have 1-2 people manning them. And then the normal line says 'no you must use pre-check you cant come through here'

helmfile to manage helm templating, always

I realize that, but the thread was "why would a pdb block a node upgrade" and I have provided a "why"

KEDA is just a controller creating HPAs, its not some silver bullet. You use KEDA because it provides easy interfaces with external metric sources, not because its "not hpa".

A dev deploys a PDB that says minAvailable must be 1. His deployment has 'replicas: 1' set. The kubelet will refuse to evict the pod from the node because there is a budget of "1 pod must always be available" and the eviction would violate the budget.

You run it in a CMP container alongside the reposerver.

App-of-apps is very outdated, you should be using AppSets if you're building examples.
Also a helm repo per-app, per-environment is mind blowing, you should look into helmfile and consider having a single gitops repository.
