Samsung's latest round of folding Galaxy Z phones and updated smartwatches were announced at its July 2026 Unpacked event and set to launch on August 7th.

The long-held understanding among security researchers and network defenders is that it's impossible to negotiate in good faith with an extortion racket because there's no incentive for the other side to actually walk away.

TL;DR Spent today rebuilding two training diagrams — a layered reference architecture and a workflow swimlane — as single-file HTML instead of exported images. The trick: data in a plain JS array, layout in CSS Grid, connectors in an SVG overlay measured at runtime . Result: diagrams you can step through, click into, and hand over as one file that opens offline. Why not just export a PNG? Because a screenshot is stale by the next sprint, and nobody re-opens the dra...

Welcome to Day 2! Today we focus on two core pillars of Object-Oriented Programming: Encapsulation: Hiding internal state and requiring all interaction to go through performing validation or controlled methods. Abstraction: Hiding complex implementation details and exposing only a clean, simplified interface to the user. 1. Access Modifiers: Public, Protected, & Private 🛡️ Python does not have strict enforcement keywords like public or private found in J...

After spending 2 years building an image compression tool, here's my no-nonsense format guide. ## The Rule | If it's... | Use... | |---|---| | Logo, icon, screenshot | PNG | | Photo, everyday image | WebP | | Smallest possible file | AVIF | | Maximum compatibility | JPEG | ## Why? PNG — Lossless. Keeps text and sharp edges crisp. Supports transparency. But files are large for photos. JPEG — Works literally everywhere since 1992. Good compression for phot...

Those who have been following me for a while will know that teaching and mentoring are a Big Deal™️ to me. Before I got into tech I was a teacher, and still consider myself a teacher at heart. Being a teacher and mentor was never separate in my eyes from being a good programmer and engineer; on the contrary, teaching was a tool that helped me become better at my craft at every stage of the journey. But in the last few years, and accelerating in the last few months, the landscape for te...

-- looks routine in review, locks your table in production: CREATE INDEX idx_orders_customer ON orders ( customer_id ); ALTER TABLE users ALTER COLUMN email SET NOT NULL ; Both of those statements hold a lock that blocks traffic while they scan or build against the table. On a small table you never notice. On a busy production table it is downtime, and a diff review does not catch it because the SQL looks fine. pg-migration-guard is a free tool th...

This is a submission for DEV's Summer Bug Smash: Clear the Lineup powered by Sentry . Project Overview I recently deployed the Dograh AI voice agent (named Zoya) live on my production website, Mobile One Media , to handle client inquiries for our 4K video production, audio engineering, and app development services. For the first 48 hours, the agent worked flawlessly. However, on day three, it suddenly stopped responding on the live site. Users were experiencing complete h...

TL;DR: Use per-test coverage data to build a reverse map (file → tests that touch it). Git diff + map lookup = run only relevant tests. 43min → 4min CI time. The Problem Everyone Has Your test suite runs for 45 minutes. You change one file. Should you: Run all 2,000 tests? (Safe but slow) Run tests with matching filenames? (Fast but broken) Manually tag tests? (Gets stale immediately) We tried all three. They all failed. The Insight: Stop Guessing, S...

Most teams already keep Playwright or Robot Framework specs next to the product. Manual cases often live somewhere else — a spreadsheet, a cloud TMS, or a wiki page nobody updates after the first release. That is why automation coverage is usually a quarterly guess: the catalog and the specs never share an id. Put both in the same Git repo , give every manual case a stable id, and linking becomes a text match. Any IDE agent can do that if the cases are files it can already see — no custom...

This paradigm shift empowers users with greater privacy and control over their personal data, while also providing robust mechanisms for verifying the authenticity ...

TL;DR I merged several training courses into one monorepo and gave every course the same numbered folder shape : 00-planning → 04-post-training . A _TEMPLATE/ you copy to start the next one, an _ARCHIVED/ you park old stuff in, and a CLAUDE.md that makes the convention machine-readable. The trick that makes it stick: templates use <angle-bracket-slots> , and "done" is a grep that returns nothing. I had course material scattered across repos — planning notes here, ...

I wired an AI code reviewer into CI, felt clever, and then looked at the bill after a busy week of PRs. Every push, every commit, sending full diffs to a big frontier model. It added up faster than I expected, and most of what it was reviewing was formatting changes and README edits that did not need a genius reading them. So I rebuilt it as two tiers, and the cost dropped hard without losing the catches that mattered. The idea is simple. Do not send everything to the expensive model. Use a c...

It started with the dumbest problem in computing: I'm in bed, a movie is playing on my laptop across the room, and pausing it requires physically getting up . Every existing fix annoyed me in some way. Remote desktop apps are overkill and route through someone's cloud. Remote-control apps want accounts, subscriptions, or a native app install. I just wanted my phone to poke my laptop over my own Wi-Fi. So I built LapDeck : one Node.js process on the laptop, a PWA on the phone. Scan ...
