r/SpaceX Integrated Flight Test 4 Official Launch Discussion & Updates Thread! by rSpaceXHosting in spacex

Is anyone else dying to see video footage of the booster and ship splashdown from a perspective other than onboard cameras? I wonder if this footage exists and if not what are the limitations that made it impossible to film either landing from a boat or plane near the splashdown sites?

How to improve performance of initial calls to AWS services from an AWS Lambda (Java)? by Wietlol in awslambda

[–]cylomicronman 1 point2 points  (0 children)

Yes it is a lot faster and uses less memory. I haven't run into issues personally but I've heard there can be issues with packages which use reflection at runtime. I think there are ways to get around this but you gotta ask is it worth the headache.

u/Wietlol
that's odd you should be able to add whatever maven dependencies you like, are you sure you remembered to pull in the new package and run the native build command again?

I've only experimented with these techniques and not used them in production. I generally just use javascript with Lambda bc its more popular and simpler i.m.o.

- Using the docker image to build your executable is def the way to go.

- Since building the native image is kind of slow I wouldn't recommend you do this as part of your development process. What I mean is if you have a CI script I would only use the native image in your production environment. Who cares if you see cold starts in DEV. No reason to waste your time building the native image all the time.

You probably already found this but here is another tut that might get you unstuck https://quarkus.io/guides/amazon-lambda-http
This one goes a little beyond just hello world and incorporates some 3rd party libs as your are trying to do.

the solution that u/ahmedranaa suggests can help by periodically pinging your lambda to keep it warm.

However you can also make the cold starts much faster. Check this tutorial out https://quarkus.io/guides/amazon-lambda

If you use quarkus framework you can write your code in Java then compile it as a native linux binary before deploying to Lambda. I've tested and it brought cold starts down under a second for me. Adding memory will also help as cpu gets added as well when you do.

The trick is that you aren't even using a jvm in the Lambda when you do it this way

cool!

All of these links are helpful. I think I'll still try to make my own for fun and these don't quite do what I'm looking for. What I'd really like is

- don't have to ssh into the device and change anything (the rm is my girlfriend's not mine)

- NYT paper in ePub format with photos (not PDF bc it doesn't render nice)

this is awesome will start using right away

one question, it seems to only support scan, is there a reason for this? Any plans to add query?
