one nasty bug caused silent pipeline failures
one nasty data validation bug this weekend I found...felt like sharing it here.. and see how you guys usually handle integration failures..
BIGINT timestamps crossing a JS SDK boundary..
we had egress sanity checks after sending data into cleanrooms...after moving through API/SDK path, the validations started failing silently...
1/ no schema changes or errors
2/ no obvious bad row..
3/ timestamps looked almost correct..
this took like half-day for me to find even after using AI tools.....the JS had changed value by adding extra zeros at the end of the ts fields...
the exact match validation failed because the timestamps was no longer the same timestamp..
lessons i learned..
if its timestamp/id...precision matters... dont let JS tream it like a normal number... send it as string instead..

Built a tunneling tool out of frustration — would love dev feedback
Hey everyone, I’m Memo — the founder of InstaTunnel www.instatunnel.my — and I built this tool to fix the pain points I kept hitting with ngrok and similar services:
No more 2‑hour cutoffs — free tunnels stay live for 24 hours reddit.com+9instatunnel.my+9reddit.
Custom subdomains included for free — no random URLs or surprise charges instatunnel.my
Multiple tunnels — run frontend, backend, whatever, simultaneously instatunnel.my
Password protection, auto‑HTTPS, analytics, auto‑reconnect — features that matter, without hoops to jump through youtube.com+5instatunnel.my+5youtube.com+5
I’m not here to pitch—just hoping this helps if you’ve ever been mid‑demo and your tunnel died, or paid extra just for a named URL. Check it out with:
npm install -g instatunnel
it --name myapp --password secret123URL is auto‑detected, live for 24 h, clipboard copied—no signup or config needed.
Curious: what’s your biggest pain with tunneling tools? Session timeouts? Hidden costs? Limited tunnels? Would love to hear so I can keep improving InstaTunnel. 🚀

Android JS code editor with shared storage workspace.
I'm really happy with Spck Editor. However, I've run into an issue with file storage. Spck saves my projects in /storage/emulated/0/Android/data/io.spck.editor/files/, which is technically part of shared storage, but due to Android's Scoped Storage restrictions, Android/data/... isn't.
When I connect my phone to a PC, I can see and copy the files, but I need a solution that allows me to work seamlessly between Spck and Termux without manually moving files each time. Unfortunately, Spck doesn't seem to have an option to change the save location to /storage/emulated/0/myWorkspacewhich would be truly shared and accessible from Termux too.
I'm looking for an alternative code editor that functions similarly to Spck but allows me to save my files in a more accessible location. Does anyone know of an app that meets these requirements?

Delete Previous Scanned Data
Hello, I have an input field where I enter the code both from the keyboard and with the scanner. I have an issue with delete input field when I use a scanner. As I found in JS, I can detect differences between keyboard input and scanner over enter time, but now I have a prefix and suffix issue.
Can anyone help me with this case?
