比賽 - Codeforces - Online Judge

馬年第一擊～

馬上開工！

今次講下大家少接觸既野 － “比賽”

前言
一路讀u都冇留意身邊朋友有邊個有“玩”過咩programming比賽，UST 有冇呢？ 其實有既。。。。係小伙子唔夠班落場姐 lol
今次我地集中了解online contest，為求令大眾易於參與，只要你想！睇少2個鐘頭電視！咁就冇野阻住你落場啦 =]

入正題
online contest 既歷史就應該10年有多了～ 多花款～有淺有深～有錢～有rank～包羅萬有～其中我推介既有這幾個
以上5個都係幾受歡迎～暫時我都係online contest過GCJ咁大把（其他都係用係用來練習下）

點玩法呢？
以codeforces為例，你可以用你喜歡既lang，寫一段code之後upload上佢server行test cases，個server會記錄返你成功定fail，每題都會有limit，例如有題目會限你10秒內pass曬d case，要256mb memory 以內，etc
但係未完喎～你接住下來係開始hack人地既submited solution，hack中左check到有bug你有會有分加，調返轉你又會比人扣分如果你自己有bug。

rules？
唔同網有唔同rules，大多跟返acm ioi 既比賽玩法。GCJ，project euler就設計上比較簡單，冇咁多限制

題目
題目每次都會有高排名既programmer設計，令到成個網有好多既contribution involved
同埋新手會由div 2 開始慢慢升，老手會係div 1 


後記～
話就話比賽姐，其實有時當下學習了解都十分好，皆因設計既題目好多元化～ 就算有準備都唔係easy，但願做多了，了解多了，時間長了，對你自己都有幫助啦～
（中大係咪好興玩online judge？！ 好多cu既人係到喎）

    Genuinely excited I found NewsFaa when searching for dependable news sources recently. The editorial team clearly prioritizes quality journalism and the daily updates cover politics, business, and technology with depth that educated readers truly appreciate.

    What makes NewsAby exceptional is its ability to simplify complex global issues without dumbing them down. The journalists clearly understand their subjects deeply, and their explanations help readers grasp nuanced topics. It's educational and informative simultaneously.

    The credibility of NewsFlue stands out in today's chaotic media environment. Their editorial team clearly values accuracy over sensationalism, which builds genuine trust. The daily updates keep me well-informed without overwhelming me with unnecessary clickbait content.

GAE - How to make a Free(Cheap) application

If you are paying huge or frustrating scaling out on your Web Application. Looking for "Cloud Solution", and your Team wish to give a try on Google App Engine. Wait... don't. not until you have learn the following things. What mistakes I made in the past 3 years with GAE ( worshiplace , BioCRF ) have given me a lot to share. Maybe there are more coming lol. 1. De-normalise datastore (ndb) "JOIN" is never gonna work in Google NoSQL Datastore - ndb. In theory, "JOIN" will cost you (in terms of money/quota) a lot. What could you do about it? de-normalise your table. Never do a second lookup will save you a lot(its depends, for BioCRF report generation save ~50% db read). Or you could choose Google Cloud SQL. It is not free, we will discuss that in the next post on "COST" 2. Take advantage on Backend Instances Hours I won't use frontend instance for serval things. e.g. report task, email task. Don't forget there are limitat...
