Reddit 的 Deploy 機制 (的歷史)

Reddit 主要是用 Python 寫的,這邊介紹了他們歷年來的 Code Deploy 系統:「The Evolution of Code Deploys at Reddit」。 最早期的時候 (2007 到 2010) 是用 rsync 更新程式碼,然後跑個迴圈用 ssh 連進去重跑: # build the static files and put them on the static server `make -C /home/reddit/reddit static` `rsync /home/reddit/reddit/static … Continue reading

Reddit 在處理 Page View 的方式

Reddit 說明了他們如何處理 pageview:「View Counting at Reddit」。 以 Reddit 的規模有提到兩個重點,第一個在善用 Redis 的 HyperLogLog 這個資料結構,當量大的時候其實可以允許有微小的誤差: The amount of memory varies per implementation, but in the case of this implementation, we could count over 1 million IDs using just 12 kilobytes of space, … Continue reading

在「Kudos - A Peer-to-Peer Discussion System Based on Social Voting」這邊看到分散式的論壇系統,帶有投票分數機制以及相關議題機制: Decentralized Reddit using a DHT to store content and a blockchain to rank such content. Whitepaper with more details here: http://lucaa.org/docs/kudos.pdf 論文裡面可以看出來設計的觀念受到 Bitcoin 的啟發,演算法也是... 換句話說,Bitcoin 帶來的影響遠遠超過金融市場,Bitcoin 所使用的理論也給其他領域很多想法。 如果這樣的系統可行的話 (還沒仔細研究 @_@),真正分散式的論壇系統就會出現了...

用 Google BigQuery 分析 Reddit 釋出的資料

前幾天有提到 Reddit 官方放出全站的投稿以及 comment 資訊:「Reddit 放出完整的全站投稿資料」,馬上就有人拿工具來分析了:「How to Analyze Every Reddit Submission and Comment, in Seconds, for Free」。 這篇的作者是用 Google 的 BigQuery 分析,而 BigQuery 跟 SQL 操作方法類似,所以我猜用 Amazon Redshift 或是 Apache Spark 應該都可以做到類似的事情吧,就看對工具的熟悉度。圖片則是透過 BigQuery 產生 csv 擋,再透過 R 與 ggplot2 產生出來。 … Continue reading

Reddit 放出完整的全站投稿資料

前幾天 Reddit 宣佈放出完整的全站投稿資料:「Full Reddit Submission Corpus now available (2006 thru August 2015)」,有些技術問題使得這次沒放出 2006 與 2007 的資料,之後會想辦法補上: Data is complete from January 01, 2008 thru August 31, 2015. Partial data is available for years 2006 and 2007. The reason for this … Continue reading
