My Stadia account is going to be deleted soon and it is a hard choice how to play games in future, even though I don't usually play any. Stadia to me is an idle game. One can check the status once in a while whether the treasure chest has renewed. Spend a high cost for a low reward, that seems to summarize my life nicely.

A portfolio is a collection of holdings, each holding has a weight, has multiple associated attributes. All data type is Double. The calculation involved are just sum and averaging, which is so easy in Java 8 Stream. So I said there is nothing to ( Read more... )

Since Fedora 28 wayland is crashing for me (Dell m4700 with external monitor), I got some time to try the nvidia GPU driver. At first I looked at https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/ which shows the actual output when ( Read more... )

To create resource without further updating it, use "ignore_changes" lifecycle property.

There are two cases we used this as a workaround. First, the lambdas are created with Terraform, but the code and configuration updates are in separate process. To prevent Terraform from overwriting code, the source_code_hash property can be ignored.
