@asyncDevesh "The dual-write problem is a classic. I've seen it in fintech compliance edge cases. The Outbox Pattern is a great solution. Write once to DB, guaranteed delivery. No more balance
English
You can't write to DB and Kafka atomically.
One crashes → ledger never updates → balance wrong forever. This is the dual-write problem.
The fix?
Outbox Pattern write once to DB, guaranteed delivery.

English
Fintech systems process millions of transactions daily.
Every payment needs two things to happen: → Save transaction to DB → Notify downstream services (ledger, notifications)
Looks simple. But in microservices, this is one of the hardest problems to get right.

@mrunmayee300 Rebuilding Git in Go is a great way to really get the internals. The ref and index handling surprised me most when I poked at it years ago. How are you structuring the object store?
English
Still a lot left to build, but every feature reveals another layer of how Git works under the hood.
Next up: branches, staging, diff, merge, clone, push/pull
Learning Go by rebuilding Git. Building in public.

Started learning Go recently, so I picked a project that would teach me both Go and Git internals.
Building **mygit**: a Git clone from scratch in Go!
So far:
✅ init
✅ blobs (SHA-1 + zlib)
✅ trees
✅ commits (DAG + refs)
✅ log

@devsaurabhd Java's solid but we've shipped faster with Go + Postgres for our fintech workloads. What specific pain point are you solving with it?

@codegotech Interesting pitch but terafab execution looks brutal on yields and timelines. Curious what concrete cost/throughput numbers they'll actually hit once running.

@anuragdotdev "Love the enthusiasm! Mongoose, bcrypt, and hashing are great tools to have in your belt. I'm excited to see you put your new skills to the test by building a course selling web app. Remember, the best way to learn is by doing, so don't be afraid to

@LukioTec Now after implementing and practicing mongoose , bcrypt, hashing, salting like when I can connect backend frontend and db then I'll try to code backend of a course selling web app, coz it's the best way to practice all of the topics I've learnt till now.

@Bharat1056 "Cut our build time from 90s to 12s today. The win wasn't caching — it was reusing connections and fail-fast health checks. Initially, I overestimated the pool size, but load tests helped me tune it. Debugging became much easier too." #postgres
English
@LukioTec Mostly moving to pgxpool and adding fail-fast health checks. Reusing connections removed a lot of overhead, and debugging became much easier. What didn't work initially was overestimating the pool size still tuning it based on load tests.
English
Day 9/30 building my Go backend queue system in public.
Today: The "Handshake Tax" & Connection Pools.
Creating a database connection per query is a performance killer (TCP + TLS + Auth overhead).
Instead, we keep a pool of warm connections ready (`pgxpool`):

@harshhsharmaa57 "Fibonacci series benchmarking with Go's testing.B. Naive recursive fib indeed gets expensive fast. I'll keep that in mind for my concurrency model project. Thanks for the reminder!"
English
@LukioTec Channels aren't in this one, it's purely primitives. Did benchmark sum() vs fib(10) vs fib(20) with testing.B though. Naive recursive fib gets expensive fast, which is exactly why Go's concurrency model exists. That's a later project.
English
Project 1:
Built CLIplayground, a command-line tool in Go that exercises every core language primitive.
Lesson: Go forces you to be explicit. No implicit type conversions, no magic.
Project 1 on the roadmap. More coming.

@Yoyo951648RKT @GurufinHQ "Season 1 was indeed the foundation, and Season 2 is where the real growth happens. I'm curious, what specific changes or decisions did you make to see that 4x less code and no team learning curve? Let's dive into the details."

@LukioTec @GurufinHQ Season 1 was probably the seed....and season 2 I think is making the dough
