How I Built a Raspberry Pi Tablet
In this technical retrospective (2014), @nkvl shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

Just nitpicking over the website: loading the gif took some time... yeah, 18MB, it was a good occasion to test gfycat: http://gfycat.com/OblongSilentAndeancat ↗ it could have been reduced to 6MB.

A compliment from Bunnie is something to be proud of! The PiPad looks awesome, well done :) I'm working on a palmtop in the vein of an HP 200LX, running RetroBSD on a PIC32 micro controller. So much fun, but gosh hardware hacking is harder than I thought. New found respect for the hardware people!
Quick grep for cost/price didn't show up anything. Sorry if I missed. How much did it cost? Just out of curiosity, I'm wondering if it's possible to build an extremely cheap but waterproof tough tablet for toddlers to play with. They don't care about performance at all.
For those interested in the actual build process and materials rather than just a writeup, here it is from his personal site: http://mkcastor.com/2014/01/02/pipad-build/ ↗
