Why I built a native libmpv IPTV player for Windows — an HDR tone-mapping deep-dive

Up front, so there's no confusion: the app I'm describing (Nightmare TV) is a player only . You bring your own M3U / Xtream Codes playlist — it ships with no channels and no content. This post is about the playback engineering, not about where streams come from. Think "VLC for IPTV," not a content service. The problem that started it I watch a lot of live content on my PC — sports, mostly. And every IPTV player I tried on Windows fell into one of two buckets: An Android app running in an emulator. TiviMate and the good mobile players are Android-only, so on a desktop you end up in an emulator or a VM. Input lag, no real HDR path, fans spinning. A thin ExoPlayer / libVLC wrapper. These run natively, but most of them treat HDR as "pass the HDR10 metadata to the display and hope." On an SDR panel — or even a lot of HDR panels — bright skies in a football match blow out to a flat white blob, and 4K HEVC with a DTS track stutters because the decode path isn't doing what you think it is. I wanted the thing that didn't exist: a native Windows player with a reference-grade video path. So I built it on libmpv — the same playback core mpv uses — with a Flutter desktop shell on top for the UI. This post is the part I actually find interesting: the HDR tone-mapping pipeline. Why HDR "just passing through" isn't enough HDR10 content is mastered in the PQ (ST.2084) transfer function against a mastering display — often 1000 nits, sometimes 4000. Your screen is whatever it is: a 350-nit SDR laptop, a 600-nit "HDR400" monitor, an 800-nit OLED. If you map PQ straight to the panel, everything above the panel's peak just clips — all the highlight detail collapses to maximum white. Tone-mapping is the process of intelligently compressing the mastering range into the display range so you keep highlight detail instead of clipping it. The naive version (a fixed curve, or clipping) is what most wrapper players ship. The good version adapts to both the content and the display. The pipeline H

I built a Brave debloater that refuses to brick your browser

(yes, its open source. link at the bottom, if u want to skip ahead!) Most "debloat scripts" are a pile of registry edits you run as admin and pray. No preview, no undo, and half of them happily disable Safe Browsing or updates for "performance." For your browser, the most security-sensitive app you run, that's reckless. So I built BraveDebloater with one rule: never make Brave less safe. It clears out the noise like Rewards, Wallet, VPN nags, Leo AI prompts, News, and telemetry such as P3A, Web Discovery, and Chromium metrics. But it flat-out refuses to disable Shields, weaken Safe Browsing, turn off updates, or touch your hosts file. That isn't a README promise. It's enforced in the tool itself. A few things that make it trustworthy: Dry-run by default. Nothing changes until you explicitly apply. Official Brave/Chromium enterprise policies, so every change is visible and auditable in brave://policy instead of hidden. Automatic backups before any change, written safely so you never end up with a corrupted file. Validated restore that checks the backup before writing anything and only touches Brave's own policy and profile files. Doctor mode, a read-only health check of your current policy state with no writes. It's MIT-licensed, PowerShell 5.1 compatible, and has a few beginner-friendly issues open. If you care about privacy or Windows tooling, I'd love a star and a PR. Check it out at: https://github.com/osfv/BraveDebloater

Zero-Day Exploit Against Windows BitLocker

It’s nasty , but it requires physical access to the computer: The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments of BitLocker, the full-volume encryption protection Microsoft provides to make disk contents off-limits to anyone without the decryption key, which is stored in a secured piece of hardware known as a trusted platform module (TPM). BitLocker is a mandatory protection for many organizations, including those that contract with governments...
