Core Viewpoint - Microsoft has removed traditional methods for creating local accounts during the Windows 11 setup process, requiring users to log in with a Microsoft Online Account to complete the installation [1][3][12]. Group 1: Changes in Installation Process - The latest updates (Build 26120.6772 and 26220.6772) have blocked previous workarounds for offline installation, such as using command prompts to bypass the online account requirement [1][7]. - Users are now forced to connect to the internet and log in to a Microsoft account during the initial setup, which impacts the installation experience [3][12]. Group 2: User Concerns and Motivations - Users previously opted for offline installation to avoid the risk of losing the 7-day return policy once the Windows system was activated online [9][12]. - Privacy concerns also drove users to prefer local accounts, as data stored locally minimizes the risk of personal information being exposed through cloud synchronization [11][12]. - Many users sought to avoid advertisements and unnecessary features that come with using a Microsoft account, which integrates them into Microsoft's ecosystem [11][12]. Group 3: Microsoft's Business Strategy - The push for Microsoft account usage is driven by commercial interests, allowing Microsoft to collect user data for targeted advertising and increase subscription rates for services like OneDrive and Office 365 [13]. - Tying accounts to the Microsoft Store facilitates the management of paid applications, ensuring revenue generation for the company [13].

Core Viewpoint - The article discusses the innovative project where a developer named Sammyuri created a small language model called CraftGPT within the game Minecraft, utilizing the game's redstone mechanics to simulate a functional AI model with 5 million parameters [6][9][15]. Group 1: Project Overview - CraftGPT was built using approximately 439 million blocks in Minecraft, with dimensions of 1020 blocks long, 260 blocks high, and 1656 blocks wide [9][6]. - The model operates on a small scale, with 5,087,280 parameters, trained on the TinyChat dataset for basic English conversations [15][16]. - The project showcases the potential of Minecraft as a platform for complex computational tasks, previously demonstrated by other projects like a 16-bit CPU and a computer running DOOM [25][26]. Group 2: Technical Details - CraftGPT's architecture includes components such as tokenizers, matrix multipliers, and multi-headed attention mechanisms, all constructed using redstone circuits [11][13]. - The model's embedding dimension is 240, with a vocabulary size of 1920 tokens and a total of 6 layers [16]. - To optimize resource usage, most weights are quantized to 8 bits, while embedding and LayerNorm weights retain higher precision [17]. Group 3: Performance and Limitations - The response time for CraftGPT can be extremely long, with simple queries taking up to two hours to generate a reply [22][20]. - The model's context window is limited to 64 tokens, restricting the length of conversations it can handle [18]. - Users are advised to use the MCHPRS (Minecraft High-Performance Redstone Server) to improve performance, as running the model on standard Minecraft could take years for a single response [22][23]. Group 4: Community and Future Implications - The project has sparked interest and excitement within the gaming and AI communities, highlighting the creative potential of Minecraft [25][34]. - Sammyuri's work raises the bar for what can be achieved in Minecraft, suggesting that the game's limitations are primarily defined by human creativity [25][33].

Group 1 - The core point of the article is the introduction of a new feature in WeChat that allows users to recall all messages sent in a single action, enhancing the efficiency of message management [3][4]. - The new recall options include "Recall this message" and "Recall all messages sent in this session," which simplifies the process of retracting multiple messages at once [4][6]. - Currently, this feature is in a limited gray testing phase, available to only a small number of users [6]. Group 2 - Different message types have varying recall time limits: text messages can be recalled within 2 minutes, while files like Word, Excel, and PDFs can be recalled within 3 hours [6]. - Users can send images in a way that allows for recall beyond the 2-minute limit by sending them as files, which can be recalled within 3 hours [7][12].

Core Viewpoint - The practice of limiting the iPhone 15 Pro Max's charging to 80% to extend battery lifespan is deemed counterproductive, as the marginal health benefits do not justify the significant reduction in daily usability [1][6]. Charging Strategy and Battery Performance - The author conducted a personal experiment over 18 months, strictly adhering to the 80% charging limit, which initially seemed to maintain acceptable battery performance [2][3]. - After 355 charging cycles, the battery capacity dropped to 91%, and the impact of the charging limit combined with natural battery degradation became noticeable, leading to increased anxiety about battery life [3][4]. - By the 17th month, with 501 charging cycles, the battery capacity fell to 89%, resulting in poor performance where the battery would deplete to near 20% by mid-afternoon, necessitating the use of a power bank [4][6]. Comparison with Other Devices - A colleague's iPhone, which did not have the 80% limit, maintained a higher battery capacity of 96% after 308 cycles, suggesting that the charging limit may not provide significant health benefits [6][8]. - Another test on the iPhone 16 Pro Max showed a battery capacity of 94% after one year with the same 80% limit, further questioning the effectiveness of this charging strategy [6][8]. Conclusion on Charging Limit - The overall conclusion drawn from the tests indicates that enabling the 80% charging limit is not worthwhile within a 1-2 year usage period, as the inconvenience of reduced battery life outweighs the minimal protective effects on battery health [6][8].
