From 4a6dab8b39dad29c9811ba8b609f8f77e1731546 Mon Sep 17 00:00:00 2001 From: eshellman Date: Sun, 24 Jan 2016 13:37:46 -0500 Subject: [PATCH] replace unrelated party link with internet archive link Judgement call. This is a 3Com "white paper". Though 3Com has copyright, white papers are typically freely distributed to advance a technology. It doesn't appear as if Prof. Ricci has anything to do with the white paper. The ooriginal link was likely lost on 3com's acquisition. I suggest replacing it with https://web.archive.org/web/20080401000000*/http://www.3com.com/other/pdfs/infra/corpinfo/en_US/501302.pdf because if the owner wants to remove it they can do so. --- free-programming-books.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/free-programming-books.md b/free-programming-books.md index f12949e53..b21a0eee2 100644 --- a/free-programming-books.md +++ b/free-programming-books.md @@ -516,7 +516,7 @@ Original Source: [List of freely available programming books](http://web.archive * [HTTP Succinctly, Syncfusion](https://www.syncfusion.com/resources/techportal/ebooks/http) (PDF, Kindle) *(Just fill the fields with any values)* * [HTTP2 Explained](http://daniel.haxx.se/http2/) - Daniel Stenberg * [The TCP/IP Guide](http://www.tcpipguide.com/free/t_toc.htm) -* [Understanding IP Addressing: Everything you ever wanted to know](http://www.di.unipi.it/~ricci/501302.pdf) (PDF) +* [Understanding IP Addressing: Everything you ever wanted to know](https://web.archive.org/web/20080401000000*/http://www.3com.com/other/pdfs/infra/corpinfo/en_US/501302.pdf) (PDF) * [ZeroMQ Guide](http://zguide.zeromq.org/page%3Aall)
