# 基金会来信

读者朋友们也许并非都知道，Berkeley Software Distribution（BSD）是 FreeBSD 的前身，它最初本质上是一个科研项目。自 BSD 早期在加州大学伯克利分校诞生以来，我们的系统就常常被用于推动科学进步，无论是计算机科学本身，还是支持物理、化学、生物等非计算机科学领域。许多如今已成为主流的技术，例如虚拟内存和 TCP/IP 协议，最初都是在 BSD 上开展的实验。早在“机器学习”这个词出现之前，全球各大学的实验室以及美国和其他国家的国家实验室就已使用 BSD 来存储和处理科学数据。

在本期 FreeBSD 期刊中，我们将探讨现代 FreeBSD 在科学计算中的应用，收录 Jason Bacon、Benedict Reuschling 和 Johannes Dieterich 撰写的文章。

本期另有关于存储的两篇文章，分别是 Jim Harris 与 Warner Losh 撰写的 NVM Express 文章——他们编写了 FreeBSD 中处理这项新型、持久化、高速存储技术的大量代码——以及 Rick Macklem 介绍的 pNFS，它允许网络文件系统（NFS）在一组服务器上并行运作，这正是科学计算社区中的常见用例。

最后，本月照例带来专栏文章：Steven Kreuzer 在 SVN 动态中讨论 pNFS 提交到 FreeBSD 一事，Michael Lucas 负责来信专栏，Dru Lavigne 通过活动日历让你了解未来几个月即将到来的全部活动。

期刊全体同仁希望，如果你正处于夏日炎炎的地方，不妨倒上一杯最令人放松的饮料，坐在树荫下，享受这份 FreeBSD 精粹的清凉合集。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://freebsd-journal-cn.bsdcn.org/20180708-da-shu-ju/foundation-letter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
