What's far worse than code that gives totally wrong results? Code that gives only slightly wrong results.

@Manixh02 Ideally a shared vault with 1Password, LastPass, etc. If not, Magic Wormhole - secure direct file transfer. magic-wormhole.readthedocs.io/en/latest/

How you guys share .env files or variables to team??

@mitsuhiko Using Neon Postgres you can create a branch for the db and run each test in isolation. neon.com/docs/introduct…

In the past I usually wrote tests against postgres stuff by creating a transaction and rolling back. This is getting harder and harder, particularly if you have more than one service. I wonder what people do nowadays for tests to run efficiently and concurrently.

@ThePrimeagen @SlutskyTom @jorandirkgreef I learned this early on from FLOSS as “Fail early and fail loudly”. Been repeating it ever since.

i have been thinking about making a video about this but it mostly comes from a talk between 2 people: john on Lex's podcast @jorandirkgreef on Mine with Tiger Beetle the idea that Joran talked about was "Tiger Style" testing and one of the tenants is test "negative space" of your program and test it in production effectively every invariant in your program you codify with asserts that crash your program whether in production or in debug

i am 19 years into programming (17 if you considering being serious) and this year i have vastly changed how i program honestly, nothing feels better than "discovering" better ways to program. it also makes me understand why it takes 30 years to master something

@yiningkarlli ZMQ has some really good options if you need different strategies, topologies, fanout, pub-sub, etc. If it’s point to point then Protobufs/CapnProto is probably the easiest to pass structured messages back and forth. As @ragecryx points out, discovery is important and tricky.

I want to write a small distributed C/C++ program that can communicate with other instances of itself on other devices over the network. What's the least fussiest way to do this these days? ZMQ? NNG? Capn Proto RPC? Just go with raw low-level websockets directly? Something else?

Wrote a CLI tool in Rust and was blown away. Gave myself about 1h to solve a problem and within 2h I had a polished solution. Used clap, nix, Rayon, indicatif, and simplelog. Result was incredibly fast and reliable. Much better DX than C++. 🦀

@TechCrunch Twitter is showing stealth ads (again). #1. Clicked on a regular image to enlarge it and instead was taken to the AliExpress website and a product page for contoured pillows! #2. Gambling post not labelled as “Ad” but menu reveals it definitely is an ad.

@engineers_feed The hardest part is finishing what you started.

The hardest part is getting started.

@ConversationEDU @GrattanInst We already have a quality crisis in the building industry. Volume builders prioritise speed over quality and compliance, as evidenced by @siteinspections" target="_blank" rel="nofollow noopener">tiktok.com/@siteinspectio… - we need to fix these fundamental problems first. Reg compliance is a minimum.

Australia needs more housing and is getting more migrants, but we need more of those migrants to help build houses. 🏠 As @GrattanInst experts write, we’d benefit more if migration provided more skilled workers that can help fix the housing shortage. #Echobox=1706563977-1" target="_blank" rel="nofollow noopener">theconversation.com/australia-is-w…

@timClicks Which libraries are you using?

Trying to make time for generative art again

@joebarnard The audiobook is extraordinary. Ray Porter does a phenomenal job of all the different voices and accents. I would recommend anything he reads!

I'm almost finished reading Project Hail Mary by Andy Weir. It is SO good and I am requesting 400 million more suggestions for books with the same vibe, thank you!

The Wes Anderson quartet of short films on @netflix from an anthology of short stories by Roald Dahl is nothing short of cinematic gold. Exquisitely carefully shot, he employs many conspicuous theatrical devices & direct narratives which break convention and beguile the viewer.

@jeffdl @engineering ??? That option is gone for me. 🫤 As to how and why it tries to download something when I select "Why this ad?" is truly baffling...

@gavinb @engineering 🤷‍♂️

This has been a year full of engineering excellence that sometimes can go unnoticed. Besides all the visible changes you see on our app, here are some of the most important improvements we have made under the hood. - Consolidated the tech stacks for For you, Following, Search, Profiles, Lists, Communities and Explore around a singular product framework. - Completely rebuilt the For you serving and ranking systems from the ground up, resulting in a decrease 90% reduction in lines of code from 700K to 70K, a 50% decrease in our compute footprint, and an 80% increase in the throughput of posts scored per request. - Unified the For you and video personalization and ranking models, which significantly improved video recommendation quality. - Refactored the API middleware layer of our tech stack and in doing so simplified the architecture by removing more than 100K lines of code and thousands of unused internal endpoints and eliminating unadopted client services. - Reduced post metadata sourcing latency by 50%, and global API timeout errors by 90%. - Blocked bots and content scrapers at a rate +37% greater than 2022. On average, we prevent more than 1M bots signup attacks each day and we’ve reduced DM spam by 95%. - Shutdown the Sacramento data center and re-provisioned the 5,200 racks and 148,000 servers, which generated more than $100M in annual savings. In total, we freed up 48 MW of capacity and tore down 60k lbs. of network ladder rack before re-provisioning it to other data centers. - Optimized our usage of cloud service providers and began doing much more on-prem. This shift has reduced our monthly cloud costs by 60%. Among the changes we made was a shift of all media/blob artifacts out of the cloud, which reduced our overall cloud data storage size by 60%, and separately, we succeeded in reducing cloud data processing costs by 75%. - Built on-prem GPU Supercompute clusters and designed, developed, and delivered 43.2Tbps of new network fabric architecture to support the clusters. - Scaled network backbone capacity and redundancy, which resulted in $13.9M/year in savings. - Started automated peak traffic failover tests to validate the scalability and availability of the entire platform continuously.

@tekbog Literally happened today fam

>ci/cd takes over 2h >devops team spends several months deleting everything and moving terraform files to make the pipeline faster >it's 2h and 25min now

Literally just installed the latest version of Node.js and on the first run I get this. It's crazy how many components, packages and frameworks you need to just to get started. #webdev #wtf

Starting a side #webdev project. A million framework/host choices! Started with @Netlify for a quick result. First wizard didn't clone sample repo due to master/main conflict. Then some weird ERR_OSSL_EVP_UNSUPPORTED error due to webpack version conflict. Not a fun start.

I don't want much. World peace. A cure for cancer. And a way to hide shows I've already watched in Netflix. #wishlist #netflix
