The Importance of MAST in the Age of Open Source Software
Building with free and open source software (FOSS) has become common practice for app developers. In 2022, it was estimated that between 70% and 90% of any given software codebase was made up of open source components. Leveraging open source...

How Open Source Developers Make Money in 2026
This May 2026 guide surveys the practical ways developers monetize open-source software in 2026, focusing on real mechanisms rather than theory. It catalogs five primary models — dual licensing, open core, SaaS wrappers (managed hosting), donations/sponsorships, and consulting/services — and describes where each works best. The article provides vendor examples (Qt, GitLab, Elastic, Redis, WordPress/Automattic, Ghost, Snyk, HashiCorp) and honest revenue ranges for projects at different scales. It emphasizes combining models, focusing on developer experience, community engagement, licensing choices, and patience; most projects earn nothing, while the top few capture most revenue. Practical recommendations cover starting with a real problem, releasing early, planning monetization, and building community trust.
Open Source License Deep Dive
This article analyses major open-source software (OSS) licenses, contrasting permissive (MIT, BSD, Apache 2.0) and copyleft families (GPL, LGPL, AGPL). It explains key textual provisions — e.g., MIT's lack of explicit patent grant, Apache 2.0's contributor patent license and patent-retaliation clause, LGPL's library exception, and AGPL's closure of the SaaS source-disclosure loophole. The piece covers license compatibility rules (notably Apache 2.0 incompatible with GPLv2 but compatible with GPLv3), common controversies and company license changes (React, MongoDB, HashiCorp, Redis, Elastic), and practical guidance for choosing licenses based on trade-offs around adoption, patent risk, and contribution reciprocity. A comparison table summarizes commercial-use, source-disclosure triggers, and patent protections across major licenses.
Open Source Delivers 2-5x More Value for Energy Grids
A new report from LF Energy and LF Research introduces the Open Source Benefit-Cost Framework, a methodology for grid operators and regulators to quantify the costs and benefits of open source software versus conventional procurement. Applied through case studies, the framework found that open source approaches can deliver 2-5x greater net value. The report evaluates strategies across total cost of ownership, risk exposure, strategic value, and societal impact. It aims to support evidence-based procurement and policy decisions as software-defined operations become strategic for grid infrastructure. The report was released at LF Energy Summit Europe in Berlin.
