为什么不用 RAG 做记忆系统 ——压缩上下文与 memory.md 的架构选择

Low-level languages like C, have manual memory management primitives such as malloc() and free(). In contrast, JavaScript automatically allocates memory when objects are created and frees it when they are not used anymore (garbage collection). This automaticity is a potential source of confusion: it can give developers the false impression that they don't need to worry about memory management.

**数据量** - 百万级 MySQL、PostgreSQL - 百万-百亿级 分析性数据仓库：Impala、Presto、GreenPlum、Apache Drill - 百亿级 离线数据仓库：hive、spark **系统架构** - SMP（Symmetric Multi-Processor

The WebAssembly.Memory object is a resizable ArrayBuffer or SharedArrayBuffer that holds raw bytes of memory accessed by a WebAssembly.Instance.

互联网架构中缓存无处不在，某厂牛人曾经说过：”缓存就像清凉油，哪里不舒服，抹一下就好了”。高品质的存储容量小，价格高；低品质存储容量大，价格低，缓存的目的就在于”扩充”高品质存储的容量。本文探讨缓存相关的一些问题。 LRU替换算法 缓存的技术点包括内存管理和替换算法。LRU是使用最多的替换算法，每次

The HTTP Device-Memory request header is used in device client hints to indicate the approximate amount of available RAM on the client device, in gigabytes. The header is part of the Device Memory API.

经常思考一个问题，为什么我们需要分布式？很大程度或许是不得已而为之。如果摩尔定律不会失效，如果通过低成本的硬件就能解决互联网日益增长的计算存储需求，是不是我们也就不需要分布式了。 过去的二三十年，是一场软件工程师们自我拯救的，浩浩荡荡的革命。分布式技术的发展，深刻地改变了我们编程的模式，改变了我们思

The capabilities of a client device largely depend on the amount of available RAM. Traditionally, developers had to use heuristics and either benchmark a device or infer device capabilities based on other factors like the device manufacturer or User Agent strings.

存储管理 在原始的伯克利Postgres系统中，有多个存储管理器。现在只剩下“磁盘”存储管理器（在伯克利，也有索尼光盘和持久存储主存的存储。但是在任何外部发布的Postgres或者任意版本的PostgreSQL中已不再支持了。）不过，我们保留了存储管理器的切换开关，以备可能有人打算引入其它种类的存储

The non-standard and legacy memory read-only property returns the size of the JavaScript heap which can be helpful to measure and reduce the memory footprint of websites.
