WebSocket support in ASP.NET Core is surprisingly awful. Why do I have to manage buffers and low-level WebSocket frames?
Deploying Kubernetes resources using Pulumi & TypeScript is such a nice experience, no more writing YAML🤩
I can't believe how cumbersome creating a new price in @stripe is. If I want to change the price or add a new currency, I have to manually create a new price, copy over every single value and currency by hand and hope I didn't accidentally make a typo.
One lesson from implementing @stripe -- A significant weakness is the inability to version products/prices. Juggling metadata, lookup keys, and active vs. archived prices adds complexity.
🎨 new technologies necessitate new interfaces with real-time latent consistency models, here’s a different kind of drawing app:
Remember back when we all read Clean Code and then to do one thing we wrote 25 small functions across several files instead of one 20-line function that you could look at and say "I know exactly what this function is doing"
Absolutely zero offense to the author, but how can anyone open this test and even begin to understand what's going on here? It succeeds – what exactly does it verify? It fails – what exactly is broken? That's the kind of code that mocking frameworks inevitably bring you toward.
10x engineers blah blah blah who cares. The engineers that impress me the most are the ones that fearlessly dive into code, domains they know absolutely nothing about and end up producing amazing work in a short amount of time anyways. Truly awe-inspiring every time I see it.
Recursive sum/union types with exhaustive pattern matching is by far and away the highest leverage programming language feature post lambdas, I wish every language would adopt
A common mistake: "Let's abstract this in case we want to replace it later." Examples: 🚫 "Let's abstract React in case we switch JS frameworks." 🚫 "Let's abstract Tailwind in case we switch CSS approaches." 🚫 "Let's abstract Mongo in case we switch Databases". This is…
Had to refund and cancel 240 customers called Jake Smith from Philippines with $7,000 in card testing payments No idea why Stripe doesn’t catch these They even passed my Cloudflare CAPTCHA?! Had to block 🇵🇭 PH payments now sorry

I am looking for an addition to our frontend team @getmimo. If you value autonomy, a great team and you like to work on a meaningful product, just reach out! jobs.getmimo.com/o/frontend-dev…
The best suggestion I have for software engineers with some experience is to learn a "different stack": dip your toes at least. If you're doing backend: do some frontend or mobile. Or the other way around. You'll learn a ton and appreciate how challenges are different there.
Our recently launched @getmimo web version has some interesting technological aspects and learnings i would like to get into the next days. The main tech choices are: • @nextjs, @statelyai (xstate) and react-query • @storybookjs • hosted on @vercel 1/
Remarkable women are actively changing the tech world! Our iOS lead Helene is one of those outstanding women in tech fighting relentlessly alongside her team to make Mimo's content & features more accessible. Read more about Helene's story👉 apps.apple.com/story/id163137…
So proud of our team that built this amazing new Mimo experience on the Web!
Great news🎉 After months of work, we can proudly announce that our app is also available in Spanish, French, Russian, German, and Brazilian versions of Portuguese. Step by step direction on how to change your language👉 bit.ly/3vVLLSP
