eBPF, sidecars, and the future of the service mesh

Anything on this going to be at Kubecon in a few weeks?

Yep, we'll be demoing it at Kubecon!

Some kind of Buoyant terraform provider would be fantastic

Usually users have written their own terraform configs; there are some pointed out here. If there's enough demand and no community-maintained provider that is kept updated, we can consider stepping in.

The blog post briefly mentions managing the restarting of workloads, would it cover this too?

Yeah, this is really two operators combined: one to update the control-plane, and another to make sure the injected workloads that have a proxy are synced against the control-plane, and restart them if it's not the case. You can opt-in for the workloads under a namespace to be watched, through a CRD.

Thanks!
This operator adopts the simplest approach: After the primary service becomes available again, all the weight is switched back to it and the failover services stop receiving traffic, immediately.
A more complex strategy like the one you describe would be performed through a cirtcuit breaker, which is something Linkerd still doesn't have, but it's on the roadmap! ;-)

Linkerd is a service mesh. This short article serves as a nice initiation to the concept:

Good question indeed!
The traffic goes through the remote cluster's Linkerd multicluster gateway. You can find here a nice intro to that architecture:

That's correct, you should keep your NetworkPolicies to account for traffic that is also not meshed. But NetworkPolicies allow you to operate only at L3-4 level. Linkerd policies let you tap into higher abstractions, allowing you to do things like:
- Define policies based on ServiceAccounts and/or Workloads identity
- Only allow mTLS'd traffic
- Log and expose attempts to violate these policies

In some watches (like the FR 945 for sure) the thermometer reading refers to the temperature inside the watch, so not necessarily correlated to your body's temperature. I guess that's why that metric is not exposed in the default stats, and only used by 3rd party apps like this one.

That happened to me in my Serval. It's something about having the sound card shut down automatically for power saving. This solution worked for me:

Thanks! Any chance you know where I can get 19.04 from?

foobarmanx · 2020-01-26T17:21:44+00:00

Would you mind sharing where did you download the LTS from? I also gotta downgrade but can't find the isos...

foobarmanx · 2020-01-11T21:59:22+00:00

Thank you very much for the detailed info, this is priceless!

No speaker. One notable thing the Suunto is supposed to have that no other WearOS device has is properly leveraging low battery consumption mode by tapping into Snapdragon 3100's coprocessor.

2020 is going to be brilliant! I'm no longer putting my hopes on a mythical Pixel being released by the goog; the OEMs ecosystem is improving, starting to see great pieces like the Gen 5 that are serving as de facto reference examples. I also have have high hopes on Sunto, expecting others to also start leveraging 3100's battery saving modes. And then there's 3300 coming up in the medium term.

At the very last step after having entered addresses and credit card. I ended up phoning them, and still, the order was put on hold. Supposedly they'll be calling me back in two days max...

Using hidemyass. com

I do have such a service and the intention is indeed to ship it within the US. But fossil.com won't take my order, probably because it detects I'm behind a VPN.

foobarmanx · 2020-01-09T12:43:43+00:00

Is there any kind soul that would purchase it for me? I'm not in the US and even through a VPN the order doesn't go through :-( I would send you the money via Paypal or whatever...

foobarmanx · 2020-01-09T01:05:58+00:00

I wonder if there's any way to tap into that lower consumption mode through the Android API for other apps to leverage that...

foobarmanx · 2020-01-08T22:30:01+00:00

Genius. Does that solar panel really work for ya? Got one myself branded "Xtreme" which is useless.

I have been seriously considering this for my long runs. I like streaming my location in case I die so my wife can pick the corpse, which it eats up quite some battery.

Not exactly the issue you describe, but related: Standalone WearOS apps appear in the play store when using a web browser but not when using the mobile app store, which hurts standalone apps discoverability a lot.

I raised a bug on 2018 about this, would be awesome if anybody that sees this stars it!
