For anyone that uses immutable infrastructure where servers’ configuration is never once built and subsequent deployments result in replacement with entirely new VMs, building once per machine still happens every time there is a deployment.

One difference between the current and previous generations is just how much information is recorded by and about us. There will be a lot more evidence of the existence and experiences of people alive today than people of a century ago. Whe

Thanks. That was useful for the further discussion in comments on the other post.

I guess the differences are how long it takes to detect a typo, and therefore the blast radius in getting it wrong in a script that could be executed many times before you notice.

It’s my understanding that you want to set the timeout in the server code to be higher than the idle connection timeout in the ALB. With them set to the same value, timeout errors will look different depending on whether the application or

Apart from pricing and the potential to overcommit resources on EC2-ECS, there are a couple of other differences. One is your options for doing forensics on Fargate. AWS manage the underlying host so you give up the option of Doing host lev

We all have laptops because: - most devs are in the on call roster for their team’s systems. - it’s really handy to be able to bring a machine to a meeting, or to go and sit with people from the team that make the API you’re trying to use.

I first read this way back when it was first published. I was still studying full time back then. I recall it being one of the things that really motivated me to learn more. It meant that there would always be something new and interesting

I read both books a long time ago. My recollection is that Code spends more time building context and explaining why something works as it does. "Elements of Computing Systems" gives more detail on how to implement many of the sam

WARNING that compose file gives the container ALL, SYS_ADMIN and NET_ADMIN capabilities, effectively giving it root on your machine. Doing that for some random image seems like a very bad idea. OP why are these needed? Can you remove them?

by lukeck 10y ago
