elixir has a type system and gta6 isnt out yet
Elixir v1.20 released! Now officially a gradually typed language: Elixir type checks every single line of code, finding bugs and dead code, without developer overhead (no typing signatures) and extremely low false positives rate. Plus a faster compiler! Links and reports below.

Have you heard that the order of the where clause matters? Back in the day, that may have been true, but unless you work with legacy systems, query planners these days are smart enough to re-order them for maximum efficiency, so you don't have to care how to order them!

what the heck did you just say about my allocations, you little vibe coder? i’ll have you know i topped my flamegraphs with zero GC regressions, graduated first in class from the school of monomorphic shapes, and i’ve been involved in countless production incidents where i personally reduced p99 with nothing but flamegraphs and a dream. i have over 300 confirmed cache hits and i’m trained in partitioned batching, O(1) LRU, and the ancient arts of structured concurrency. you are nothing to me but another source of short-lived objects. i will pre-size your arrays before you can say capacity, reuse your batch containers with object and array pools, and clear them so hard that v8 will promote nothing to old-gen. you think your abstractions can save you? adorable. i streamline your hot path, hoist Date.now() out of tight loops, keep your result objects shape-stable, and keep your span attributes lean—just what matters, not your entire life story. you’re hiding behind Cursor Pro? i’m rolling with pre-sized arrays, pooled buffers, and a request deduper dialed in to a 20ms window that snapshots then swaps like a sushi conveyor. your workers are capturing the wrong references? i pass batch snapshots into fibers so new arrivals never touch the old containers. timers? one per partition, closure capture minimal, window tight. GC pauses? i’ll make them so small the event loop forgets they existed. you think cpu limits on eks will throttle me? i don’t run limits—I run headroom. i’ll crank UV_THREADPOOL_SIZE when zlib and crypto get chatty, keep the main thread pristine, and offload your sync rocks to workers. your JSON churn? streamed. your registry ops? partitioned. your root-zone batches? right-sized so we don’t balloon live sets for fun. mark my words: i will reduce your allocation rate, i will smooth your event-loop delay, and i will lower your tail latency with precision refactors you won’t even notice in the diff. you’re compiled, bundled, and shipped with --max-old-space-size you don’t even need anymore. welcome to the strongly-typed, memory-friendly, p99-disciplined world. enjoy your stay.

For an IT guy, LinkedIn is like a reverse dating app. Beautiful women message you first, and you immediately ghost them.

2020:  Ask your roommate to be in a sketch about microservices (which he knows nothing about) 2023: For 3 years people stop him and say “you’re the microservices guy”. He gets engaged, still the “microservices guy”

that’s the point guys, iCloud is a thing. 💡i always go for the lowest (and cheapest) RAM option, and then just make it use my 2TB of iCloud for swap. i don’t pay extra because i need iCloud to store my and my family’s photos anyway, and it got quite some free space for swap
Apple in 2023: MacBook Pro starts with 8GB of RAM. iCloud starts with 5GB of storage.

This meal just cost me $1,008 in San Francisco. This is why Americans think the economy is terrible. – at San Francisco, CA
This meal just cost me $78 at Newark Airport. This is why Americans think the economy is terrible.
Readers added context they thought people might want to know
The price of the burger and fries is $17, which means that all or part of the other $61 of the tab is due to the glass of whiskey shown in the photo. nypost.com/2023/09/21/dav…
