Have you ever worked on a Guitar Pro tab, saved it, and then realized you couldn’t edit it anymore because it was “locked”? Or perhaps you downloaded a tab that was perfect but needed just one small tweak, and the author had locked it?

I recently went down a rabbit hole reverse-engineering this “protection” mechanism in Guitar Pro 8. What I found was a classic case of “security through obscurity” — and not very deep obscurity at that.

Cross Gate (魔力宝贝) was one of the most influential MMORPGs in Taiwan and China during the early 2000s. As someone who spent countless hours collecting pets in this game during my childhood, I recently embarked on a nostalgia-driven project: extracting all the pet sprites from the game files and building a modern web viewer to browse them.

After 15+ years of note-taking, I finally said goodbye to Evernote. Here’s the technical journey of migrating 4,330 notes—with all their attachments, tables, and formatting—to Apple Notes.

最近读到的一本文字流畅，内容清爽的小书。书里描述了大学教授杨素秋，在西安市碑林区文化旅游局挂职一年，筹办区图书馆的经历。这是个繁杂、具体，有时甚至需要挑战权威的工作：

• 区里提供的馆址是个地下空间，需要在有限的预算内，找到合适的装修公司，把这个地下空间改造成舒适的阅读空间。
• 在图书采购过程中，供应商惯于提供劣质的，滥竽充数的图书，为采购者支付回扣。作者不屑于收受回扣，一心为公，希望图书馆里都是经历了时间检验的好书。
• 为一个图书馆选书，工程浩大，无法仅凭一己之力完成。作者发动自己的人脉，联系了诸多好友帮忙选书。选书缘由，荐者心路，作者缓缓道来，推卷而述，好不痛快。

尽管困难重重，作者心有所往，逆流而上，不畏险阻，最终得偿所愿。主线之余，作者夹叙一年挂职生活所遇的形色人等，有的让人牙关紧咬，有的让人唏嘘感慨，说尽人情冷暖。西安的美食，官场中的本色不改，选书朋友们的人生故事，对弱势群体的关照，五味杂陈，乒乓作响，读者吃到的是酸辣爽口的一餐。

纳瓦尔·拉维坎特（Naval Ravikant）在《纳瓦尔宝典》中不仅分享了他关于财富和幸福的智慧，还推荐了大量影响他思维的优质书籍和博客。这些推荐读物构成了一个完整的知识体系，涵盖科学、哲学、商业、灵修等多个领域。

每个人都是一座冰山。当你与人交谈，想象你是在和冰山交谈，目之所及的只是水面之上的部分。如果你希望达成交流，你必须具备耐心，从身体和情绪感受出发，逐层递进，弄清原委。

为了增加用户活跃度，微信读书团队开发了一个微信小游戏——问答 PK。这是一个双人对决形式的知识问答天梯，题目内容主要基于常识，比如成语填字，古诗词接上下句。

玩了几天后发现，光靠我的知识储备和记忆力，很难持续提升段位。答案在网上一搜就能找到，但是 10 秒钟的答题时间来不及搜索，于是我想到借助 DeepSeek 来自动答题。说干就干，Vide-Coding 了一个 Python 脚本，自动化了整个答题过程，并最终达到了最高等级。本文记录在开发过程中，遇到的问题与一些观察。

Sundar Pichai: CEO of Google and Alphabet | Lex Fridman Podcast:

Sundar Pichai views “moonshot” projects as crucial for several reasons:

• Driving Innovation: He believes that aiming for audacious, seemingly impossible goals, like the original moon landing, forces radical rethinking and leads to breakthroughs that wouldn’t happen with incremental improvements. It’s about finding “10X” improvements rather than “10 percent” improvements.
• Inspiring Talent and Passion: Big, challenging problems ignite both the hearts and minds of people. It’s easier to attract passionate and talented individuals to work on projects that could redefine humanity.
• Societal Impact: Moonshots, even if their initial goal is not fully realized, can lead to numerous technological advancements with real-world applications and inspire future generations. For example, Google considers fighting climate change as a “moonshot” due to its profound societal importance.
• Leveraging Constraints: Pichai has also highlighted that constraints can act as catalysts for innovation. Working within defined limits encourages teams to be more creative and focused, leading to groundbreaking ideas.

To monitor our baby from other rooms, we purchased a Nanit Baby Monitor. Using image recognition, Nanit provides insights into our baby’s nighttime sleep patterns through its app. Each state transition point includes a video for review.

However, the display isn’t very intuitive — the chart doesn’t show the exact timestamps for each transition. For example, the start and end times of the two longer sleep sessions are not clearly marked.
