CodeWithStu

Hey hey 👋 Lots of new people recently, so let's get to know each other I'm Stu. I'm a principal engineer who has spent years at places like Checkout and ClearBank. Whilst I'm building my future, I share interesting things and what I learn on the way What are you working on?

@devadam88 So many hybrid roles at the moment not looking forward to this part again :(

As a London based developer do you commute 2 hours a day? 🇬🇧

Graph for the year so far is looking pretty good. I had a measly 235 contributions last year 🙈 Lots of thinking over the past few days ready to execute on another side project... :)

@googleanalytics @marclou - idea for datafast ;)

Did you know you can now connect your GA data directly to LLMs like Gemini? ✨📊 By setting up the new Model Context Protocol (MCP) server, you move from manual reporting to strategic, AI-powered analysis. ▶️ Hit play to see the complete setup process → goo.gle/47CsGrA

@altryne I don’t think they’re ignoring the bugs to get more cash. More likely is that it’s buried in a ton of other noise/feedback. This bug actively hurts their infra as well because it’s more to process.

PSA: If you've been running out of Claude session quotas on Max tier, you're not alone. Read this. Some insane Redditor reverse engineered the Claude binaries with MITM to find 2 bugs that could have caused cache-invalidation. Tokens that aren't cached are 10x-20x more expensive and are killing your quota. If you're using your API keys with Claude this is even worse. This is also likely why this isn't uniform, while over 500 folks replied to me and said "me too", many (including me) didn't see this issue. There are 2 issues that are compounded here (per Redditor, I haven't independently confirmed this) : 1s bug he found is a string replacement bug in bun that invalidates cache. Apparently this has to do with the custom @bunjavascript binary that ships with standalone Claude CLI. The workaround there is to use Claude with `npx @anthropic-ai/claude-code` 2nd bug is worse, he claims that --resume always breaks cache. And there doesn't seem to be a workaround there, except pinning to a very old version (that will miss on tons of features) This bug is also documented on Github and confirmed by other folks. I won't entertain the conspiracy theories there that Anthropic "chooses" to ignore these bugs because it gets them more $$$, they are actively benefiting from everyone hitting as much cached tokens as possible, so this is absolutely a great find and it does align with my thoughts earlier. The very sudden spike in reporting for this, the non-uniform nature (some folks are completely fine, some folks are hitting quotas after saying "hey") definitely points to a bug. cc @trq212 @bcherny @_catwu for visibility in case this helps all of us.

A DynamoDB migration took down our game for thousands of players. 700+ Lambdas & 1 Dynamo table. One migration caused an outage. I built a pattern we dubbed ActionRunner to fix it. View the full breakdown: youtu.be/iRaqyrAFHFg

@Aaronontheweb @dariogriffo Assuming this will affect people that run a lot of tests locally with TestContainers etc

@Aaronontheweb @dariogriffo Just saw this part as well. Not sure what the fair use is, but why is something in my CI subject to a fair use?

Thanks localstack.. You have been a great buddy... All our builds started failing today.

@dariogriffo This is literally the best way to annoy your community in one go. If there was an alternative I would switch

@CodeWithStu From today they enforced the licensing model. Kinda... There is still one month setting a variable to bypass the check.

Wrote up some of the performance techniques that I've been using in my #dotnet #aws library if you're interested in that sort of thing :) codewithstu.tv/thoughts/dotne…

@edandersen Yeah that’s entirely possible as well. Is there a world anymore where prices come down?lol

@CodeWithStu Or he is telegraphing that token costs are going up 10x

Software engineers will not be trusted to spend 50% of their salary on variable opex costs with no guarantee of productivity, unless they are executive level. this is a pipe dream to sell GPUs

Put this in perspective that’s 200 million tokens used per day. Every working day of a year. Definitely possible but requires an extraordinary amount of thinking to know what to develop in this case. In addition to using tokens to debug logs etc (eg: plug direct to aws cloud watch). I think most people are taking it to the extreme though. He’s talking more about the productivity rather than the actual number (despite it being mentioned i feel)

I plan mode first and don’t accept the plan without a test plan. I also run everything plan through sequential-thinking mcp before i even look at it (agent instruction). Then i have explicit agent instructions for medium/high risk changes to spin up separate agents and do code review and security review in parallel (has no execution context window this way). The output is so much better for this and catches a ton of bugs before i even see anything

Just let Opus go for over an hour on a new feature. When it was done, I asked how I can test it. 20 minutes later, it realized I can't test it because it did the whole thing entirely wrong. Idk how you guys use this model every day for real work 🙃

@RealProductGirl Yes exactly. My wife was sending todo lists via whatsapp, and i was struggling to remember some things like when the MOT/service was due. Hopefully it helps others :)

@CodeWithStu I love this! I'm assuming you came up with this to organize your household? I think it's awesome!

I NEED my feed full of builders. What are you working on right now? I don't care if it's a startup or a weekend side project. If you're building something, I want you on my timeline. Reply and let's connect. 👇

@DanKulkov At least it tried i guess

@TeeDevh It’s amazing how many people forget about bing webmaster tools. Structured schemata is a must (eg: json-ld)

My SEO setup so far: • sitemap.xml submitted and cleaned up • robots.txt configured • Google Search Console connected • Bing Webmaster Tools connected • Meta titles and descriptions set • Canonical issues fixed • Duplicate/redirect issues cleaned up • www → non-www 301 redirect fixed • Cloudflare DNS / SSL issue resolved • Internal links cleaned up • Waiting on Google recrawl + validation What else should I add?

@thekitze Can’t show my wife, don’t have a 3d printer yet 🙈😅

OH LAWD WIFE APPROVAL GOES BRRRRR
