I'm brave enough to say it: Linux is good now, and if you want to feel like you actually own your PC, make 2026 the year of Linux on (your) desktop
Linux has become genuinely user-friendly for desktop use, especially for gaming. Distros like Bazzite make it easy to run games without command-line knowledge, often matching or exceeding Windows performance through Valve's Proton. Steam's Linux user base hit 3.2%, surpassing Mac. The main appeal is ownership and control—no forced AI features, bloatware, or upselling. While HDR support and some anticheat software remain issues, they're improving. Linux offers a viable alternative for users tired of Windows feeling like rented software rather than something they truly own.

Why there’s no European Google?
Europe hasn't produced tech giants like Google or Facebook, but has created fundamental infrastructure that powers the modern internet. The World Wide Web (HTTP/HTML), Linux, Git, Mastodon, VLC, and LibreOffice are all European inventions released as open source common goods rather than privatized for profit. European success is measured by long-term contribution to humanity rather than short-term wealth creation, with technologies designed to benefit everyone through copyleft licensing. This approach has produced lasting infrastructure that will outlive any individual company.

The Human in the Loop
AI has fundamentally changed software development workflows, but human review and judgment remain critical. While AI can generate code rapidly for bug fixes and features, engineers must review every change to ensure correctness, security, and architectural fit. The bottleneck has shifted from coding speed to review capability. The role of programmers who simply execute tasks is obsolete, but software engineers and architects who provide judgment, understand context, and maintain accountability are more crucial than ever. The real risk isn't AI replacing developers, but creating a culture where shipping unreviewed AI-generated code becomes acceptable.

Open source MySQL repository has no commits in more than three months • DEVCLASS
MySQL's GitHub repository has seen no commits since September 2025, coinciding with reported Oracle layoffs in the MySQL team. Commit activity has declined yearly since 2019, reaching its lowest point in 2025 since the project began. Industry experts suggest Oracle is focusing on proprietary MySQL versions (Enterprise, Cluster, Heatwave) while neglecting the open source community edition. Despite concerns, MySQL remains the second most popular database among professional developers according to Stack Overflow surveys, though PostgreSQL now leads. Experts recommend migrating to alternatives like MariaDB or PostgreSQL, though migration can be challenging due to SQL dialect differences.

Stop using MySQL in 2026, it is not true open source
MySQL's development has significantly declined under Oracle's stewardship, with commit activity dropping sharply in 2025 and staff reductions announced. Oracle conducts all development behind closed doors, rejecting community contributions and treating MySQL as open source only by license, not practice. Technical issues have plagued recent releases, including data corruption bugs, performance regressions of 15%, and difficult upgrade paths. Oracle published 123 CVEs in 2025 with minimal transparency compared to MariaDB's 8. Migration to MariaDB is straightforward for most applications, offering true open source development with active community participation. Major platforms like Wikipedia and 57% of WordPress sites already use MariaDB.

Raising money fucked me up
A founder shares their psychological struggle after raising pre-seed funding from respected former bosses and angels. Despite having supportive, pressure-free investors, they found themselves paralyzed by self-imposed expectations and fear of disappointing people who believed in them. The mental burden led to counterproductive decision-making, focusing on vanity metrics and growth speed rather than strategic fundamentals. After reflection, they realized the investors backed them as people, not just an idea, and that following their own process matters more than matching other startups' timelines.

The Impact of AI on Tailwind CSS and Open-Source Sustainability
Tailwind CSS experienced a 40% drop in documentation traffic and 80% revenue decline since early 2023 as developers increasingly use AI tools to generate code instead of visiting documentation. This forced the company to lay off 75% of its engineering team despite remaining the most popular CSS framework. The situation highlights challenges for open-source monetization models in the AI era, though major sponsors like Vercel, Supabase, and Google AI Studio have pledged support to help Tailwind adapt.

The Claude Code Situation
Anthropic recently enforced restrictions preventing users from using Claude Code subscription tokens with third-party tools like Cursor and Open Code, requiring users to either use Claude Code exclusively or pay significantly higher API pricing. While this was always in their terms of service, the sudden enforcement after months of tolerance has sparked controversy. The enforcement appears motivated by multiple factors: debugging difficulties with third-party integrations, the competitive threat from rapidly growing open-source alternatives like Open Code, and potentially severe cost subsidization issues. The move undermines developer goodwill at the peak of Claude's popularity and suggests Anthropic wants to lock users into their entire stack rather than just their models, possibly due to unsustainable economics in the AI infrastructure race.

AI is destroying the web
AI tools are fundamentally changing web development in concerning ways. While they help senior developers code faster, they're causing significant problems: Tailwind CSS saw 75% staff cuts despite 28 million weekly downloads because AI tools bypass their documentation site. LLMs predominantly generate React/TypeScript/Tailwind code, reducing ecosystem diversity and creativity. Beginners learning primarily through AI may adopt poor coding practices that slip into production. The sustainability of open-source projects is threatened as large companies benefit without supporting maintainers, potentially leading to abandoned frameworks that AI models depend on.

"please stop" - maintainers
Open-source maintainers are increasingly closing external contributions due to an overwhelming influx of low-quality, AI-generated pull requests. Projects like TL Draw, Curl, and Zig have shut down or restricted contributions because AI-assisted PRs often contain poorly structured code that creates maintenance nightmares. The ease of using AI tools has lowered the barrier to entry, but removed the need for contributors to develop expertise, build relationships, or understand project architecture. Maintainers are drowning in "AI slop" that looks superficially helpful but creates technical debt and requires significant effort to review and fix. The recommendation is for contributors to invest time learning projects deeply, joining communities, and handcrafting quality contributions rather than relying on AI to generate quick PRs.

Architectural Choices in China's Open-Source AI Ecosystem: Building Beyond DeepSeek
China's open-source AI ecosystem has shifted toward Mixture-of-Experts (MoE) architectures as the default choice, prioritizing cost-performance balance over maximum capability. Leading organizations expanded beyond text models into multimodal domains (video, audio, 3D), with growing emphasis on small models (0.5B-30B parameters) for practical deployment. Apache 2.0 became the standard license, reducing friction for production use. A significant strategic shift emerged toward hardware-first development, with models increasingly optimized for domestic Chinese chips (Huawei Ascend, Cambricon, Baidu Kunlun) in both inference and training. Companies are open-sourcing production-grade serving systems and infrastructure, moving competition from isolated model performance to full-stack ecosystem design.
