- [See nodes in] random combinations. We need to be able to shuffle our notes around to generate new insights.
- It’s now more important to do the opposite: finding information that contradicts or disconfirms what we know. Discovering information that contradicts what we currently believe is the new frontier of learning.
- 我发现最合适的还是以笔记软件为主、轻量提醒工具为辅的组合（目前我的组合是 Notion + Dislike）。
提前规划，统筹安排
- Value total organizational throughput.
- [Pay attention to] how much coordination and agreement cost must be spent preventing inefficiency

Code review – from good to great
In a team I sat next to, a junior developer asked a senior to conduct code review for a newly completed feature. According to the process, that Senior had to approve all changes going to production. Here is how it went: Senior: “No, I am busy.”

Our remote work future is going to suck
As COVID-19 continues to alter the way we live, there is a scramble to predict what our “new normal” will look like. After the virus fades away or, God help us, becomes a constant in our day-to-day life for years to come, which change brought on by the pandemic will stick?
- eventually competing with the global talent market
- Remote enables you to be forgotten
How we migrated Dropbox from Nginx to Envoy
- [Nginx,] although it is event-loop based, is it not fully non-blocking.
- Envoy uses threads instead of processes. It relies on libevent for event loop implementation. Envoy does not have any blocking IO operations in the event loop.
- Nginx showed higher long tail latencies. This was mostly due to event loops stalls under heavy I/O
- Envoy has the ability to stream access logs over gRPC.
- Envoy has control RPC.
- Envoy has a unified data-model for configs: all of its configuration is defined in Protocol Buffers.
- Envoy relies heavily on modern security practices. It uses AddressSanitizer, ThreadSanitizer, and MemorySanitizer. Its developers even went beyond that and adopted fuzzing.
Blockchain
UTXO Management for Enterprise Wallets introduced two wallet models, Send-Only hot wallet and Send-and-Receive Hot Wallet. It also has many interesting discussions about the utxo management.

Apps Usage
- 时间就应该更多花在演示设计上
- 明确演示目标
- 听众（汇报对象）是谁？
- 核心信息是什么？
- 这个汇报在什么场景下展示？
- 如果是演讲，那就要考虑「矛盾导入」「发现问题」「分析问题」「解决问题」的逻辑。
- 如果是工作汇报，那就要考虑「结论先行」「论据补充」的「金字塔逻辑」。
- 数据
- 过往案例 (纵向)
- 其他企业案例 (横向)
- 有了大概的思路后，可以考虑把提纲画好，并明确清楚哪些素材有了，哪些素材还欠缺。
- 可以考虑找到一些相关领域的专业知识，用它来提纲挈领，整体便有了高度。
- 展示准备
- 设计包袱
- 互动
- 视频
- 幽默
用好 Keynote 和 iMovie，在 iPad 上做出有高级感的视频 - 少数派
- 使用 Keynote 神奇移动
- 用 Videoleap 这个 App 的「色度」工具同样可以抠除背景。
- 在 Mac 平台出现了一款叫 Design Camera 的软件，实质上是高度自动化的 3D 模板带壳截屏，可以生成运动立体的带壳截屏视频。这款叫 SceneShot 的App填补了 [iOS] 这一空白，它可能是目前带壳截屏类App中最高级的了，它提供 3D 模版供你调整，并可以定制背景和环境光线，甚至还有特效滤镜等等功能。
- 之前介绍过的 Canva，最近刚更新了视频制作功能
Hardware
- Apple 不仅处理掉了第三方的 CPU，且一并处理掉了第三方的 GPU。
- Mac 这次的芯片变革需要撑得起未来十年，其最优解便是将专精芯片以最优工艺的整合在 Soc 中。
- 最高支持 100W 充电功率
- 与 PD 兼容
- 考虑购买更为通用的 PD-PPS 充电器，并且尽量购买支持电流到 5A/支持电压到 20V 的充电器，为下一代即将到来的 PD-PPS 快充作准备。而在购买 Type-C 线缆的时候，也请优先考虑购买最大承载电流达到 5A 的充电线。
