Understand
Explainers and guides that go beyond the headline and provide context.
Why Bluetooth headphones lag in games but not in videos
Video players can delay the picture to match the audio. Games must react to unpredictable events, exposing the latency accumulated through encoding, transmission, and playback.
Why HDR screenshots can look washed out or too dark
The display, operating system and image file may represent brightness and color differently. The problem usually appears during HDR-to-SDR conversion, not while pixels are copied.
Why some pages do not appear in the Wayback Machine
Finding a domain on the calendar does not mean every URL, image and feature was preserved at the same moment.
Why videos lose quality every time they are uploaded again
Downloading a platform copy, editing it, and posting it again starts another compression pass. Resolution may stay the same while detail, color, and motion deteriorate.
How passkeys replace passwords without sending a secret to the site
Each service receives a public key; the private key remains under the authenticator or credential manager’s control and signs challenges after local unlocking.
Why online games stop working when their servers shut down
Having the files installed is not enough when authentication, match rules or progression live in remote services the client cannot replace.
Why a game update requires so much free space
The downloaded file is only one part of the process: the system may still need to decompress data, rebuild packages, and temporarily keep old and new versions.
Bit rot: why digital files can become corrupted without warning
Keeping a copy does not prove it remained intact. Checksums can expose silent changes, but recovery still depends on redundancy and maintenance.
How rollback netcode works in fighting games
The technique responds to local input before receiving the opponent’s data, then re-simulates the match when a prediction fails, trading constant delay for occasional corrections.
How 4K film restoration works
The number describes the new master’s resolution, not an automatic transformation: material selection, physical repair, scanning, cleanup, color, sound and ethical choices come first.
Shader compilation stutter: why games hitch even at high FPS
Brief pauses can appear when a game encounters an effect for the first time because average frame rate and frame delivery consistency measure different problems.
Frame generation: why doubling FPS does not halve latency
DLSS, FSR, and XeSS can make motion smoother by inserting intermediate images, but the game still responds at the pace of the frames it actually renders.
Case studies
Decisions, outcomes and lessons explored in depth.
Mastodon case study: how independent servers formed one social network
The project showed that a shared social experience can exist without placing accounts, rules, and infrastructure inside one company.
Let’s Encrypt case study: how ACME automated HTTPS
The certificate authority removed price and manual work from issuance, but its lasting effect came from an open protocol that any client can implement.
Kiwix case study: how an open reader took Wikipedia beyond the internet
The project separated content, archive and reader to turn entire websites into portable, searchable libraries that do not depend on continuous connectivity.
Blender case study: how the community bought freedom for the code
A €100,000 campaign turned software threatened by a company shutdown into open infrastructure for 3D creation.
OpenStreetMap case study: how a community map became digital infrastructure
The open database separated data, presentation and services, allowing communities, companies and humanitarian teams to build maps for different needs.
ScummVM case study: how reimplemented engines keep old games accessible
The project neither distributes classic adventures nor simulates an entire computer: it rebuilds the executable layer while leaving original game data with the player.
Jellyfin case study: how a fork preserved an open media server
The community started from the last open Emby release, kept the server under GPLv2, and rebuilt clients and governance without adding a premium tier.
OpenRCT2 case study: how an open engine modernized RollerCoaster Tycoon 2
The community reimplemented the engine, removed limitations, and added multiplayer while keeping an important boundary: assets from the original game are still required.
AO3 case study: how fans built an archive outside platform logic
Ad-free and donation-funded, Archive of Our Own combines open-source software, volunteer labor, and a taxonomy designed to preserve fanworks.
Proton case study: how Valve brought Windows games to Linux
The compatibility layer combined Wine, graphics translators and Steam integration to reduce reliance on native ports, while anti-cheat and DRM remain important limits.
Blender case study: how open films became a laboratory for 3D software
Open Movies do more than demonstrate Blender: real productions expose bottlenecks, shape tools, and return reusable files to the community.
Sonic Mania case study: how fangame creators built an official release
Experience accumulated through tools, remasters and fan communities enabled an external team to rebuild 2D Sonic within a production supervised by Sega.

Reading that stays useful beyond the news cycle.
OLED burn-in: why permanent marks can still appear
Uneven wear, brightness and static elements explain the issue; extreme tests do not represent the varied use of most viewers.
Why subtitles do not exactly match dubbed dialogue
Subtitles, closed captions, and dubbing come from the same work but follow different constraints for reading, duration, synchronization, and accessibility.
Shader compilation: why PC games stutter the first time
Average FPS can remain high while creation of a new pipeline delays one frame. Caching, precaching and advance delivery reduce the problem.
The soap opera effect: why movies look too smooth on TV
Motion interpolation creates frames that are not present in the original video. It can reduce some motion problems while changing the cinematic look.
Retcon, reboot and alternate universe: what each term changes in comics
A new origin can revise the past, establish another continuity or simply open a new issue-numbering cycle. Those consequences are not equivalent.
Kernel-level anti-cheat: why games use privileged access
Running a driver close to the Windows core expands visibility into cheats, but it also increases the impact of failures and requires trust in the vendor.
OpenStreetMap case study: how a collaborative database became global infrastructure
The project separated data, maps and services so communities, companies and humanitarian organizations could reuse and update the same representation of the world.
Comic book variant covers: what A, B and 1:25 mean
The art changes, but the story is usually the same. Here is how open-order covers, incentive ratios and store exclusives affect availability and price.
MAME case study: how an emulator became hardware documentation
The project preserves machines by reconstructing their behavior in code while keeping technical documentation separate from access to protected ROMs.
How Star Trek helped shape modern fandom
Before social media, fans were already organizing campaigns, conventions, zines and their own stories, changing the series’ fate and the relationship between audiences and franchises.
Let’s Encrypt case study: how automation helped make HTTPS the default
The nonprofit certificate authority removed price and manual work from the equation, while ACME turned certificate renewal into routine infrastructure.
Why subtitles and dubbing do not say exactly the same thing
Both versions start from the same dialogue, but they must solve different constraints involving reading, timing, performance, and lip synchronization.
