#Lambda
Hadn't thought of using EFS as a shared cache.. #lambda #awscomsum
Bundling code running in AWS Lambda has really poor downsides.
First downside is a build step. Second debugging is harder.
Yes sometimes sourcemaps can work, with additional setup, but that's also obviously slower than not needing to. Aside the fact they do not always work.
Better: not needing to bundle. We've found we don't need to with http://arc.codes

@Ryanbigg What's the context? Arrays have indexes, not keys, but could contain hashes. Assuming all hashes:
```
[{a: 1}, {b: 2}, {c: 3}].
map &:keys
```
Maybe :index, :at, or :each_with_index depending on why you're calling :[] on Array elements. Otherwise:
```
key = :b
[{a: 1}, {b: 4}].filter { _1[key] }
# => [{:b=>4}]
```
My personal favorite, with #lambda helper:
```
k = "key"
try_key = ->(e) { e[k] rescue nil }
[0, {"lock"=>1}, {"key"=>2}].
map(&try_key)
# => [nil, nil, 2]

It plays terribly at the moment, but it's good enough to work on the UX.

AWS Lambda Error Handling: Everything You Need to Know by @theburningmonk
I've got a #serverless function in #lambda happily ticking over. The idea that it lets you focus on business functionality and let the cloud do the rest... it depends. Sometimes it is #YakShaving all the way down. I got an e-mail that some lambda is using an old version of node. It appears it is not one that I wrote, but something that is used to rotate logs. Then I find that https://docs.aws.amazon.com/cdk/api/v1/docs/aws-apigateway-readme.html CDK v2 is now the new normal. Was looking forward to that when developing. But not now :-).

✨ Writing and deploying Rust Lambda function to AWS: Image glitch as a service (author : @virtualkirill )
https://www.kirillvasiltsov.com/writing/write-deploy-lambda-image-glitch/
I still see the odd #Lambda around, here and there, from time to time.
The longest-running #LGBT radio show in #Dallas (the US?) is #LambdaWeekly. #LambdaLegal was important to the #US Marriage Equality fight. The #LambdaLiteraryReview is still out there reviewing #Queer books. Etc…
But yeah, for the most part, at least in my little corner of the universe, it’s been eclipsed by other symbols, such as rainbows and pink triangles.
In the 1970s, there was an effort to make the Greek letter lambda the symbol of gay liberation. “Universally recognized" is overselling it quite a bit – it was known in some circles, mostly in the USA.

Put together an annotated more complete multi binary AWS sam example which is closer to my standard Go project structure. This deploys to provided.al2 runtime using arm64, and custom compile flags to trim down the binary. #aws #lambda #golang https://github.com/wolfeidau/sam-golang-multi-lambda

A quick dive into Y combinators and how to make a recursion without referencing a function by its name.
I am excited to have found this book. It is called 'Let Over Lambda' and it's all about macros.
I already discovered a lot of interesting stuff in the first chapters. For example, TIL how to use 'labels' to define local scoped recursive functions: I'm in awe. Now I am trying to understand the implications of it.
I've already hit #AWS #Lambda's default 5s timeout fetching just two #mastodon timelines with https://schizo.social. I'm going to need a more clever solution for making multiple API requests to build a single page. Maybe prefetching, maybe spawning a background process and updating the UI via a #webSocket when they complete? I'm trying to keep it as client-side #javaScript free as I can, but waiting on multiple masto servers just isn't going to work...
This is pretty rough, deprecating go1.x and forcing customers over to provided.al2 which is pretty annoying with its constraint on handler being `bootstrap`. For those using a zip file with more than one command in it this is a pain.. 👎😞 #lambda #AWS https://aws.amazon.com/blogs/compute/migrating-aws-lambda-functions-from-the-go1-x-runtime-to-the-custom-runtime-on-amazon-linux-2/

I wrote a new AWS Lambda function to pull my TV and movie watch history and ratings from Trakt into my Now page. Still on the lookout for bugs, but it seems to be mostly working as expected. There’ll be some junk and duplicates on my Now page for a little while as I test and settle into a new routine.

I just finished an overly-documented Rust-powered #lambda calculus interpreter:
https://github.com/orsinium-labs/rlci
4 years ago, I got into lambda calculus by watching [1] and implementing [2] on #python the Lambda Calculus workshop by @dabeaz, and I still think this is the most mind-blowing thing I know (on par with category theory). Learning #Rust was an excellent excuse to dive into it again.

Daniel Vassallo, in his book ”AWS The Good Parts”:
"Treating Lambda as a general-purpose host for your applications is risky. It might look compelling at first -no servers to manage, no operating system to worry about, and no costs when unused-but Lambda's limitations are insidious hidden risks that typically reveal themselves once your application evolves into something bigger."

My new favorite AWS tool is the AWS lambda runtime interface emulator, in short it allows me to run and test lambdas locally using CURL commands! Showcases how handy it is to package lambdas as containers as well. 😎 🌤️ https://github.com/aws/aws-lambda-runtime-interface-emulator #AWS #lambda
Alright I made a thing. Calling it “Obelisk” because it allows a single Lambda function to route complex request paths with `find-my-way` (Fastify’s router). Basically just an adapter so it’s super fast and small.
The demo site explains more: https://jxrrngx355.execute-api.us-west-2.amazonaws.com/
If nothing else, read my fevered disclaimers from earlier (still kicking COVID).
Source code is lacking because I need to clean it up a bit.
Also, I'm still questioning whether it's a good idea 🫠
#NodeJS #Lambda
Anyone knows how to run a background service in an #AWS #Lambda deployed as a #Docker #container?
The #AWS #Lambda logo will never stop being the Half Life logo in my head, sorry Amazon #jsday2023
Response streaming for #AWS #Lambda is great, because it makes sending large responses to the client. This can remove the need to use S3 as the download location for dynamically generated payloads.

I spent entirely too long benchmarking Neon #Postgres serverless driver in a #Lambda. Pretty compelling stuff!
Tested against #DynamoDB (with @arcserverless) and added my thoughts here: https://craft-86c.begin.app/
Refresh a couple times after seeing a really sleepy result. It's the Neon boot time.
Going to try PlanetScale on Friday.
dear #aws #serverless folk:
all the "do a thing with #lambda" tutorials and docs i'm finding assume you're setting up an #apiGateway in front of your function. if i'm using lambda to push an external event into another external api (so aws doesn't own the authentication), is there a reason to not just use the raw function url and skip the gateway? it seems very faffy and i'm not sure i need what it buys me.
Did AWS really think rolling out custom Lambda runtimes absolves them of the promise of managed functions-as-a-service?
Scary if true!

I just had a flash of insight into container (and #AWS #lambda) "layers". If I think about them as image editing "layers" (and ever further back, as cel layers for hand-drawn animation https://conceptartempire.com/cel-animation/) it all makes sense to me in a way it hadn't before.
Photoshop layers, but for the file system.
One of the more obscure cloud #webdev terms is "utilization". The idea used to be that we needed more servers than generally necessary to accommodate spikey traffic.
This meant in traditional architectures the majority of your cloud bill was for idle under-utilized compute resources.
With #aws #lambda we pay for compute on demand by the millisecond. Which us #serverless folks call 💯% utilization.
