5Chat Control passed first round in EU Parliament
- The European Parliament voted 331-304 to allow a renewed vote on "Chat Control" legislation that would permit tech companies to voluntarily scan private messages for child abuse material. The controversial measure, which expired in April, faces criticism as mass surveillance despite child protection justifications. The procedural maneuver gives proponents tactical advantage as only a simple majority is needed for passage while amendments require an absolute majority of 361 votes.
Legislative manipulation and democratic concerns
Users criticize EU's procedural tactics to pass Chat Control, including timing votes before summer break when MEPs are absent and requiring higher vote thresholds for rejection. Many see this as undemocratic manipulation after multiple previous rejections.Chat Control 1.0 vs 2.0 clarification
Discussion clarifies this vote extends existing Chat Control 1.0 (which allows but doesn't mandate message scanning) rather than the more controversial Chat Control 2.0 (which would require scanning). The original regulation had expired in April.Impact on privacy and messaging services
Users worry about global implications as other countries may copy EU regulations, potentially forcing messaging services to comply worldwide. Some advocate for decentralized alternatives to resist government surveillance efforts.
6Microsoft fire idTech team at Id software

798% isn't much
- The article argues that 98% success rates, while impressive for exceptional achievements, are inadequate for basic expectations. In web development, a feature working for 98% of users means excluding millions of people. The author emphasizes that robust engineering requires graceful handling of edge cases, not just serving the majority, as 98% support still fails 2% of users who deserve functional access.
Context matters for the 98% standard
Developers debate whether 98% success rates are acceptable, with many arguing it depends on business context, resources, and user base. Some say targeting niche markets makes 98% plenty, while others note compound failures and network effects can amplify the impact of that 2%.Real-world analogies illuminate the problem
Users share relatable examples like cleaning Christmas tree needles, weeding yards, and restaurant experiences to illustrate how small percentages of failure become highly visible and problematic in practice, making 98% feel inadequate.Browser compatibility and market share measurement
