how to delete a git tag locally and remote
# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName
標題: Spark 線上競賽平台
大綱:市面上很多線上解題平台例如LeetCode,但是目前沒有一個平台可以讓使用者在線上用 spark 解題.
為了推廣 spark 應用,SparkTW 自行建置了一線上平台,可以供使用者使用 Spark 解題.
使用者可以在線上即時的使用 scala 或 python 編輯,當送出答案時,伺服器會在 runtime 編譯使用者的 code,並呼叫 Spark 比對答案.
使用者可以線上看到自己的每一題的註冊次數,花費的時候,以及其他好手們的成績.
演講內容會包括搭建平台時技術上的細節,包括前端如何支援 Code Highlight,如何將 Code 送到執行 Spark 的伺服器,以及如何將結果回傳.
為了增進使用者體驗,平台端花了很多時間解決像是 Spark Job 排程問題, 加快 Scala 編譯的速度,以及透過 RDD 直接比對結果等細節.
解題平台(https://codefight.sparktw.ml/)已於 2017/9/30 正式上線使用,
