From dc09453a77f33c4dfdff306321ce93cf5fbd2d57 Mon Sep 17 00:00:00 2001

Subject: First steps on converting FeedSub into the pub/sub basis for OStatus
communications: * renamed FeedSub plugin to OStatus * now setting avatar on
subscriptions * general fixes for subscription * integrated PuSH hub to
handle only user timelines on canonical ID url; sends updates directly * set
$config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have
hubs (won't actually receive updates though) * a few bits of code
documentation * HMAC support for verified distributions (safest if sub setup
is on HTTPS)
And a couple core changes:
* minimizing HTML output for exceptions in API requests to aid in debugging
* fix for rel=self link in apitimelineuser when id given
This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions.
Needs some further cleanup to treat posts as status updates instead of link references.

+پروژهی هاروارد، قدم دوم
+http://editormyself.info/archives/2005/10/051012_014641.shtml
+اگر یادتان باشد چند وقت پیش نوشتم که دانشگاه هاروارد پروژهای دارد با نام آواهای جهانی که در آن به وبلاگهای غیر انگلیسیزبان میپردازد. خواشتم که اگر کسی علاقه دارد ایمیل بزند. تعداد زیادی جواب دادند و ابراز علاقه کردند. حالا وقت قدم دوم است.
+
+
قدم دوم این است که برای اینکه مسوولین پروژه بتوانند تصمیم بگیرند که با چه کسی کار کنند، میخواهند نمونهی کارهای علاقمندان مشارکت در این پرزوه را ببینند.
+
+
برای همین از همهی علاقماندان، حتی کسانی که قبلا اعلام آمادگی نکرده بودند، میخواهم که یک موضوع رایج این روزهای وبلاگستان فارسی را انتخاب کنند و در هفتصد کلمه، به انگلیسی، بنویسند که وبلاگدارهای دربارهاش چه میگویند. لینک به پنج، شش وبلاگ و بازنویسی آنچه آنها از جنبههای گوناگون دربارهی آن موضوع نوشتهاند با نقل قول مستقیم از آنها (البته ترجمه شده از فارسی) کافی است. دو سه جمله هم اول کار توضیح دهید که چرا این موضوع مهم است.
+
+
متن نمونه را به آدرس ایمیل من hoder@hoder.com و نیز برای افراد زیر تا روز دوشنبه بفرستید:
