無線電視舉辦的「普選港姐」以失敗告終，全城市民均大表失望。據知，今次的普選系統網絡服務與軟體開發工作，無線找上Cherrypicks承辦。而Cherrypicks則選上微軟(Microsoft)充當技術支援。數月來，這份軟體經過多次測試，也在臨陣一朝破身，可謂丟盡這兩家大公司的架。

據知，該承辦商並不是第一次與TVB合作，之前的觀眾互動節目，有同樣的遊戲環節，也相安無事。豈料今次卻令這兩家公司甚為尷尬。被Cherrypicks選用的微軟Windows Azure雲端計算系統，是透過向外擴充來展開，理應能應付大規模的應用。假設，每個處理核心每秒可以處理100位觀眾的投票，當擴展至40顆核心時。其線性擴展就可提供每秒處理4000位觀眾的選票。

十分鐘內，處理約240萬票，即是大約1/3香港人的投票舉動，聽上去十分可靠。唯主持阿叻無奈地說「太踴躍」「Down Server」「無辦法」，又是否只因踴躍而導致系統壞掉？又是否真的「無辦法」？當然，有不少人都會以「瘋狂Refresh」的方法來增加投票的成功率，但這樣又會大幅增加系統的付擔，實數如何，我們現在只能猜測。不過，雲端空間，只需要買就成，錯估用戶行為與數量而沒有預先配備所需空間，就是TVB與Cherrypicks的量算不周了。

有事件的「案內人」就向《主場新聞》透露，至少有另外兩家承辦商，也曾考慮接下這個「全港首創」的專案。其中一家慣與AWS(亞馬遜網絡服務)合作，後來他們也選擇放棄，因為TVB提出難以峻工的期限。這位爆料人士還說：

「時間才是最大問題吧。兩個半月就要從『零』建設到『在App Store上架』，情況有點似上星期塌下的哈爾濱大橋吧。」

呢個app 應該好簡單, 只係投票之麻, 其實兩個半月時間唔算好短了.
香港人做野好快的, 再短時間, 再大既project, 小弟都見唔少.

呢個case, 我估(因為我資料不足, 所以只能斷估) 係有人低估流量, stress test 做得唔好吧.

yes.. and Window Azura sucks. Our company has a team in Shanghai using that for a new project and just down. Luckily, still in development stage. Sucks..

and i think for 2 1/2 months.. yes. you can roll out a product, but is it a good product? can it survive under load? I don't think they don't even have time to do it. probably at the last minute, they are still working on the feature and just making sure deployment is good, then go live.

The Miss HK is 5"4 (correct me if I'm wrong...)...that's a bit short in today's standard.

Typical of Microsoft Product.

Ever new version (excel, outlook and etc.) is worse than the last version.
Anyone miss Windows XP here?

If you go here, you can count there are at least 5-6 港姐冠軍 from Vancouver.

online voting system, should be a simple project la. For this case, just have to consider the volume of transaction and possibility of hacker attack.

LUCKILY, they did not ask for consultation service from my team. hohoho

咁多年溫哥華出左咁多港姐華姐同女星，點解都剩係我識得佢地但係佢地唔識得我…

I am sure it was just overloaded. A company as big as Apple was not able to keep their site up when iPad 3 was released couple months ago.
As for the Microsoft product. They actually do make very good products, including Windows7 and their server products. While it's not perfect, I just don't think there's anything better out there with all the feature and compatibility it provides.

I think it's about the time and the resource needed for a smooth operation.
Voting is VERY VERY tricky.
It fails almost every time even for organizations as big as governments, no body get it right.  Don't expect TVB can get it right.

Apple server down, blizzard server down, activision server down, ....  All these are the one of the most technological advance companies in the world.  And you expect TVB to get it right?

What most companies don't realize (or the person who pays for the service) is that if they prepare to let 2 million people to log in at the same time, they have to assume 200 million connections (because of crazy amount of reconnects and retries).  Let say the cost for prepare 2 million connection is 100k. Who will pay 100 times that for smooth service? TVB would say "Fcuk off".

There can be some very smart tricks here and there to reduce the amount of connections, but these requires lots of time to research and develop and it's different for each project.

I have some theories for voting system in the near future to make voting system possible and affordable.  hint: cloud service.

The set up is grossly under power and can only handle 4000 TPS. It is more likely, everyone wanted to vote would be waiting in front of their computer for the poll to open. The load won't be spread evenly in the 10 minutes. Also the flood of requests may jam and crash the network before they can even get to the servers.

They need a 128GB Ram and 128 CPU Cores Cloud Server....

作者: Catpiano 時間: 2012-8-29 13:07

So .. I don't follow this news ..

What the heck is 普選港姐 ?? people vote online for miss HK??

Well .. we all know everything from TVB is from their own "high" staffs ga la... 普選??

作者: 快樂牛郎 時間: 2012-8-29 13:32

LOL
HKers can simply vote by not watching
but they still choose to watch so that's what they have decided for themselves
