I wonder if you could build on Jeff Geerling's work: https://www.jeffgeerling.com/blog/2022/using-4g-lte-wireless...


This is a great read, but I always seem to run into cases where I need to define something like a security group and then reference it when deploying ec2 instances. I'd love to decouple to reduce my plan time, but I haven't figured a way out as of yet.

To be fair, I haven't used terraform -chdir yet.



-chdir is useful, but nothing to do with this (it's literally just cd before running command).

As sibling said, use data source to read remote state outputs.


not sure what you mean here.

Do you use the same security group for all of your instances?

i am usually creating a security group per group of related ec2 instances.


you can pull it in via a data source, but then of course this creates a coupling between multiple modules/state files.


I didn't catch this when it was announced earlier this week - I can't say I'm surprised given COVID's effect on things.


The concept is easy to grasp, but for me the challenge is figuring out which testing framework/suite is best for the language I'm dealing with (and then learning the intricacies of how the tooling works).


There's millions of frameworks out there. I don't think it's worth learning the details of those things. It's like learning one persons very specific way of folding clothes. If you want to use one go for it, but to use one for learning? Waste of time.

You don't need a framework to do TDD. Can't you put your assertions and functions and tests in some iterative loop?


Not just Terraform, but the rest of the Hashicorp suite is powerful and relatively easy to pick up. At the tail end of last year I taught myself Terraform and I'm looking at Vault next.


Although this seems to be in the beginning stages, I'll be really interested in seeing how they handle the management aspect of Docker. How will networking play out between containers on a single host? Multiple Hosts? The idea of enabling vMotion for individual containers is also pretty interesting. Networking between containers seems like a decent fit for NSX.

This also addresses my main complain about docker in the enterprise - most all docker hosts are VMs themselves, and running docker on a VM host that is running on a hypervisor seems a bit redundant. This could provide all the benefits of containers while removing the middle man (e.g. CoreOs/Ubuntu/whatever).


Enterprise is understandable - businesses may prefer not to use Pro. I don't believe that you can count Windows 10 Mobile/Mobile Enterprise against the count as they are merely part of Microsoft's effort to combine all their platforms under one operating system.


I really like the idea of having an independent mesh network for all my devices/things to track - and at least during pre-orders it seems like a less expensive alternative to other bluetooth tracking devices. The Verge did a write up on Pixie with more details [1].

I can't imagine it was dumb luck that the drunk driver hit that tree, I'm guessing there was a bet/challenge involved.


Hrm, that looks pretty neat, but as someone completely new to mechanical keyboards, I wonder if it would be a good starter.


Probably not, since it requires a bit more work than just a keyboard you can buy. I would say something like the CODE Keyboard, WASD Keyboard, or Ducky Shines are good and reliable keyboards.


I'm not opposed to doing some soldering - I'm mostly interested in the entry price. The lack of arrow keys concerns me a bit (but I suppose I could use their layouts to account for that). I'll give those keyboards a look though, thanks!
