Longform YouTube videos should be called YouTube pants.

The serving size is 3/4 of a pickle. A wholly unreasonable unit. Presumably to have the calories round down to 0.

I'm a fan of this surrounding logs feature in the new CloudWatch Logs Analytics console.

Submitted a PR to the lambda-perf repository to enable visualization of performance trends over time. For example, coldstarts for llrt on arm/.zip/512MB have gotten slower. See more here: github.com/maxday/lambd...

Way back I wrote an Alexa skill to tell me if it was recycling week. It effectively did a n%2===0 on the week of the year. After 8 years of node updates I can confirm it's faster and easier to just look out the window and see if my neighbors' bins are out.

They've surrounded our transfer station with roses. It's surprisingly effective at limiting the stank.

Since everyone forgot how to write json by hand after the AI meteor strike of 2021 caused permanent darkmode, Speedrun 1.55 can now generate the necessary json config to wire your GitHub markdown to your AWS accounts with just your Identity Center start url. github.com/No-Backspace...

Good news! That 50ms coldstart latency regression that appeared when using the AWS Javascript V3 SDK on Lambda with Node >= 22 is now fixed. github.com/aws/aws-sdk-... Update your dependency to v3.1011 to get back in the fast lane. Comparing my patched v3.1006 to v3.1011 shows no delta.

I ran my benchmark overnight to confirm there wasn't much improvement when turning on NODE_COMPILE_CACHE with Lambda Coldstarts. It's less than a 10ms improvement. There may be benefits with larger packages but for my setup (200K zip file) it isn't worth the trouble.

I experimented today with enabling NODE_COMPILE_CACHE to see if it would make Lambda coldstarts faster. I was able to create a .zip file with the cache from a previous run. I verified node used the cache successfully with NODE_DEBUG_NATIVE="COMPILE_CACHE". It didn't reduce the coldstart time 🫠.

LLRT v.8.1-beta has the fastest p50 InitDuration by 130ms. But if you measure E2E time from the client (what you should measure), it narrows to 79ms over AwsLite and 118ms over a modified AWS v3 JavaScript client on Node 24. This is likely due to the size of the LLRT binary being ~5MB.

Anecdotally I've noticed Lambda nodejs coldstart latencies trending down but visualizing the improvement using the daily maxday numbers is hard: maxday.github.io/lambda-perf/ I pulled the data and graphed it. Indeed, it's showing a 20-30ms improvement since November last year. Here's nodejs on arm.

Getting the client ip address when using a Lambda Function Url generally works, but sometimes you get a spoofed one. In this article I cover how to workaround the undocumented mangling Lambda does to the `x-forwarded-for` header. speedrun.nobackspacecrew.com/blog/2026/03...

I discovered that if you use Lambda furls, the x-forwarded-for header is truncated to the leftmost value. If you front your furl with CloudFront, the ip in that header is spoofable. CloudFront appends the viewer ip to the value of x-forwarded-for. Workaround is: github.com/aws-samples/...

TIL I was still using http 1.1 to connect to my api which supported http3. Because http3 is still kind of broken in Firefox: bugzilla.mozilla.org/show_bug.cgi... and when you enable http3 in CloudFront using the CDK, it disables http2. github.com/aws/aws-cdk/...

TIL you can get edge location in your CloudFront Functions. docs.aws.amazon.com/AmazonCloudF...

Hello darkness my old friend. I just updated to JQuery 4.0.0. Ready for 10 more years of $.

PSA: There is a performance penalty when using named exports with ESM import vs. require on built-in node modules. This is why the AWS JavaScript V3 SDK has 50 ms slower Lambda coldstarts on Node 22+. Some notes here: github.com/aws/aws-sdk-...

Look, the plating and bread choice leaves room for improvement. But the flavor of my latest Persian-American cuisine; the sumac avocado toast slaps.

After many exasperated console.log's I looked at the docs and discovered CloudFront functions don't run on responses with a status code >= 400. So my edge metrics only work on successful requests. docs.aws.amazon.com/AmazonCloudF...

It's important to know someone in London. Eventually you'll need their help unsubscribing from Domino's UK marketing because the US is region blocked 😂.

I swear AWS had some hero image on a docs site with this hotel carpet vibe once.

Took a quick break from the curiosities of London to have a curry and a pint with Cloudflare's lord of logs and corduroy trousers @ankcorn.dev

A short story: 1. This showed up in the group chat 2. Replied with "Nicolas UNCAGED?" 3. Checked El goog to see if this pun was a world first 4. Alas

Boris is still at it and still gets it. Logging properly is on you and rn your: loggingsucks.com

The answer to why account based endpoints didn't reduce the blast radius of the DynamoDb Oct event was in DAT458. They don't point to cells yet, they still point to the regional endpoint🤦‍♂️. youtu.be/YZUNNzLDWb8?...

I'm relishing using AI to click the bait for me.

Clearly the old spice product marketing team was cut from the same cloth as me.

This is very clever. Tom Larkworthy shows how to unaggregate CloudWatch metrics and some neat insights you get when you do: observablehq.com/@tomlarkwort...

I got Cloudflare Workers to act as an API Gateway and do granular throttling for a Lambda using github.com/mhart/aws4fe... 1. I really like 𝚠𝚛𝚊𝚗𝚐𝚕𝚎𝚛 𝚍𝚎𝚟 to rapidly iterate 2. Cloudflare Workers are way better than CloudFront Functions

There is not a deep enough place in hell for the continue reading button, the random playing video and the slop ads below the fold.

Been messing with Cloudflare Workers after reading @boristane.bsky.social boristane.com/blog/what-ar... Delighted to find how easy it is to implement granular api throttling: developers.cloudflare.com/workers/runt... Something I've wished I could do with Cloudfront Functions for some time.

I've started tagging my CDK projects so I can find them on disk when I inevitably need to upgrade the Lambda runtime.

They briefly mention the account based endpoints in the writeup: aws.amazon.com/message/1019... But my question remains, were those endpoints also impacted? Were the teams that couldn't get to dynamo not using the account based endpoints?

Ha! Something good came of the AWS incident Monday. I purchased a day pass to SlingTV to watch the Mariners play only to find I bought the wrong color (bought orange instead of blue which had the game). There aren't refunds on day passes, but due to the outage, they refunded me. I'll allow it!

When the dust settles with the DynamoDB DNS issue, i'd be interested in understanding if it impacted the main DNS only: dynamodb.us-east-1.amazonaws.com or also the account id based DNS: <accountid>.ddb.us-east-1.amazonaws.com? The account id DNS should have reduced the blast radius in theory.

One nice thing about cycling is the tool roadkill. This is the second pair of lock-jaw pliers I've found in the street.

I wrote about migrating my API from Node 22 to LLRT and the dragons I battled on the way. speedrun.nobackspacecrew.com/blog/2025/10...

We did it fam. I successfully got my api working on LLRT. I had to switch to hono, drop jose, and modify some request parsing for form data, but IT WORKS! Seeing 188 ms Init Duration vs. 375 ms for Node 22. Warm requests with AWS service calls are like 60ms faster too.
