CloudFormation (CFN) is not going to take your chaklader.pem and create a pair key in AWS. You have to do it before hand yourself. And you can't use CFN for that as it is not supported, unless you will program such a logic yourself using custom resource.

The easiest way is to create or import the key "manually" using AWS Console, SDK or CLI. Then you can reference its name in your template.

The Go code you provided will not impact the way how the Time instance will be serialized as you are parsing it back into Time after serializing it to a string.

If you have control over how your date fields are serialized, you can apply the following format that should be aligned with what you provided to Jackson's ObjectMapper:

Try using the filename in variable as shown below. Notice the {} around variable. Ensure that your ls command returns only 1 file. For multiple files use multiple -F arguments.

Sample test data:

If you are using angular-cli, simply set projects..architect.build.configurations.production.outputHashing to "none" in your angular.json

The reason this happens is quite interesting. Since gettimeofday would use a syscall that is called very often, linux uses a thing call vdso, which is a so that is mapped automatically in your program in order to access the things related to the time information without the need of a syscall (since syscalls are costly).

The way this works is that when you call gettimeofday, your program will look for the symbol in vdso. and when it finds it, i will cache it in its memory for faster accesses. thats why the first call is slower. You can find a way better explanation here

Oftentimes the C library will do detection with the first call and then cache the result for subsequent calls.

And a nice way to benchmark the vdso vs the actual syscall here

sqlserver-ee is for Enterprise Edition which does not support t2.micro. I guess you want sqlserver-ex (express edition).

tags is a map, and your var.tag_for_ec2 is already a map. So it should be:

Use variables to reuse values in the same module. If you want to access other modules resourcesLets use the data attribute.

Example: start with using a module:

This depends upon the processor architecture, system and application design. Your basic reference is this Wikipedia article.

In an embedded system where the result and latency of polling a particular device may be the most important and central purpose of the system, you are likely to see a tight loop busy-waiting at processor instruction speeds (micro/nanoseconds) with low jitter. These intervals may not be completely deterministic due to modern processor architecture improvements such as speculative branching depending on the surrounding code; see this relevant StackOverflow answer.

In a multitasking system doing lots of things and occasionally polling for, say, keystrokes from a HID of course there will be considerably higher latency in units more like milliseconds. Tasks may switch, processes may be swapped in and out etc.

This is a quick answer to your quick question - trying to put you into the ballpark but making clear that there could be a lot at play here depending on your environment. If this helped, please consider choosing it as your preferred answer. Thanks and good luck!
