3. If you are useful, it doesn't mean you are valued (betterthanrandom.substack.com)
本文探讨了职业生涯中“有用”与“被重视”的关键区别。两者表面看似相似（如获得晋升、奖金等），但深层含义不同。
“有用” 指在特定领域高效可靠，能填补任务空缺，为上级减少麻烦。但你主要被视为执行者，负责完成必须但未必核心战略的工作，缺乏对方向的塑造参与。
“被重视” 则意味着被邀请参与更多决策对话，不仅执行，更能帮助影响发展方向，并获得更多有意义的成长与贡献机会。职业生涯路径更清晰，可能担任更具战略性的角色。
作者通过自身经历阐释区别：
- 危机中被重视：公司面临困境时，作者不仅未被裁员，还获得高额留任奖金，因领导层认为其对塑造未来战略至关重要。
- 表面成功实则停滞：另一角色中，作者虽业绩突出、获丰厚奖励，但始终未被邀请参与战略讨论或新挑战，感到自己只是“有用的看管人”，最终因缺乏价值认同而离职。
文章最后建议读者超越表面奖励，审视自身是处于“被利用”还是“被重视”的境地。

11. Whatever happened to cheap eReaders? (shkspr.mobi)
Way back in 2012, The Guardian reviewed an eInk reader which cost a mere £8. The txtr beagle was designed to be a stripped-down and simplified eReader. As far as I can tell, it never shipped. There were a few review units sent out but I can't find any evidence of consumers getting their hands on one. Also, that £8 price was the subsidised price when purchased with a mobile contract. Their w…

18. How reliable are MicroSD cards? (old.reddit.com)
这项对MicroSD卡可靠性的研究通过大规模压力测试展开，对256张不同品牌的卡进行持续写入与验证，至今已写入超47PB数据并使105张卡失效。其核心发现如下：
整体可靠性不佳：82%的测试卡至少出现过一次错误，平均首次错误发生在约2,400次读写循环时。近半数卡在达到约4,500次读写循环时，错误率便超过0.1%的感知故障阈值。约四分之一的卡预计在3,100次循环前就可能完全失效或达到该阈值。
品牌表现差异显著：
- 表现较好：Amazon Basics（零故障）、Delkin Devices（无错误）、Kingston（工业卡优于SanDisk，整体高于平均）、Kioxia（Exceria Plus/G2系列良好）、Lexar（整体高于平均）、OV（高于平均）。
- 表现较差：ADATA（低于平均）、Gigastone（大部分失败）、onn.（全部早于2000次循环失败）、Silicon Power（过半失败且失败点低）。
- SanDisk/WD：虽常用，但发现易突然失效且对电压波动敏感，14张完全失败。
- 注意：Kingston、Kioxia、Lexar、Samsung、PNY、Transcend等品牌部分产品线表现好于平均，但同一品牌不同系列表现可能不同。
名牌与非名牌卡无显著差异：测试中“名牌”卡与“非名牌”（技术消费者不熟悉的品牌）卡在可靠性上差异很小，平均故障循环数分别为约5,300次和4,900次。但“假卡”表现最差，平均仅约2,200次循环。
卡片失效模式多样：最常见的是在初始化时卡在电源启动序列中。其他模式包括永久写保护位被置位（数据可恢复）、CSD寄存器损坏（导致容量识别错误）或所有扇区返回损坏数据。
购买渠道有影响：从亚马逊购买的卡在可靠性测试中表现优于从AliExpress购买的卡。
