Show HN: I made a private self-destructing image hosting site in Golang
So I'm a junior Go dev and I made a small site that allows me to share images with someone privately and securely, and give me control over how many times the private link can be shared and how long the image will be accessible for. There are similar services to this one, but they are either convoluted with ads, or require sign-up, or expect you to fill out a survey or something. picburn is small, safe, and has no interest (nor the code or the server space) for storing your uploads. give it a tr...

Nothing throws when redaction fails
Read this first: You don't need a frontier model to redact PII
Asked to redact a PII-dense document, llama3.1:8b sometimes answers: "I cannot provide information that could be used to identify an individual." That is a 200 response containing a well-formed English sentence. Write it into your destination field and the original document, every name intact, carries on downstream. The record looks processed.
That was the pattern behind most of the problems we hit while benchmarking six r...

Most system design interviews focus on diagrams. Real systems fail because of trade-offs.
I've noticed that many system design discussions (and even interviews) spend a lot of time drawing boxes and arrows, but very little time discussing the trade-offs behind architectural decisions.
For example:
Should you optimize for consistency or availability?
When is a monolith actually a better choice than microservices?
Is event-driven architecture worth the added complexity?
How much latency is acceptable if it improves scalability?
When should caching be avoided instead of ...

How I Built ToolHub: A 138-Tool Static PWA That Stays Sub-Second
Hi everyone! π I recently published a full architecture retrospective on building ToolHub β a clean, privacy-first, zero-bloat suite of 138+ in-browser web utilities.
Here is a summary of the key engineering tradeoffs and technical decisions that allowed us to keep the site sub-second fast and fully offline-capable.

β‘ 1. Next.js Static Export (output: 'export')
Instead of running a node server for SSR/ISR, we opted for a 100% static export model hosted on...

What Happens to Your Integration When Your Payments Vendor Gets Acquired
If you follow UK tech news, fintech M&A shows up often enough that it's worth planning for as an engineering risk, not just a business one. A few recent examples make the pattern pretty clear.
The pattern shows up more than you'd think
When Visa acquired Plaid in a deal reported at $5.3 billion, the acquisition itself didn't break anything overnight, but it changed the trajectory of the product: enterprise first commercial terms became more prominent, and smaller teams increa...

Stop Calling Everything Impostor Syndrome: The Myth of "Just Push Harder"
Not everyone who doubts themselves is suffering from impostor syndrome. Sometimes the real problem lies in the strategy they've chosen, and that's exactly why it's so important to learn to tell the difference.
I read a lot of articles here on DEV about burnout, impostor syndrome, and similar topics. I thought I'd add my own perspective because I have the feeling that some advice, often given with great confidence, can actually do more harm than good. The symptoms may be real, but the diagnosi...

Catching wrong LLM outputs when you have no labels
A shorter, code-first version of a piece I first published in Towards AI on Medium.
If you've pointed an LLM at a pile of documents to extract a field β a total, a date, an amount β you know the uncomfortable part: it returns an answer for every document, all equally confident, and some are wrong. You can't check them by hand, because not having the answer is the whole reason you reached for a model. So the wrong ones ship silently.
I spent a couple of weeks on this and landed on something...

BYD has a Humanoid Robot. Automate 2026 says the Assembly Line is not ready for it yet.
August 2026 opened with two signals that appear contradictory but are actually the same story told from different vantage points. BYD - the EV manufacturer that has outcompeted every Western automaker in its core market - officially launched its humanoid robot at the Di Space technology center in Shenzhen. On the same day, analysts at Automate 2026 - the largest industrial robotics show in North America - warned that humanoid robots remain years from deployment on actual production lines. The se...

What Building an AI-Assisted SD-WAN Taught Me About Network Automation
Disclosure: I contribute to the development of QuickSDWAN. This article reflects what I've learned while working on AI-assisted networking software and isn't intended as an independent product review.

Why Managers Still Lose the Dinner Rush on Three Tablets
Designing a Multi-Tenant Restaurant OS: Unifying POS, KDS, and Aggregators
In multi-unit restaurant operations, the greatest engineering enemy is state fragmentation. When a restaurant relies on one proprietary terminal for in-house dining, separate tablets for delivery aggregators, and manual spreadsheets for inventory, operators face severe blind spots during peak volume hours.
This article outlines how we designed masova βa multi-tenant restaurant operating system that unifies POS tic...

React useDisclosure Hook: Manage Modal & Drawer State (2026)
Every React app accumulates toggleable UI β a confirmation dialog, a mobile nav drawer, a settings popover, a notification panel. The state behind each one is always the same: a boolean, a way to open, a way to close, and maybe a callback for analytics or focus management when the transition happens. So you write useState(false) and three inline handlers, copy-paste it to the next modal, and somewhere around the fifth disclosure widget you notice you've scattered the same five-line pattern acr...
