總是在農曆過年前後報到的電腦詛咒…

去年的農曆新年是一段難忘的年假…為什麼?因為整個年假都在進行零組件測試,主機不明原因無法過電(後來我老婆告訴了我原因,我兒子把Power/Reset當電動玩具在不斷地進行壓力測試…後來就突然再起不能),一開始猜測是電力不夠,所以把所有能下線的先下線,不過還是沒有用,因此猜測是主機板掛了,跑去買了一張新的主機板+CPU+RAM(因為原有的CPU太舊了已經買不到相對應的主機板了),結果仍然無效???心中一股寒意,難不成要我換整套???,最後狠下心了,只好連Case也全部換新。

買來了所有的新零組件,心中仍不死心,一定要給他找出問題來,最後終於找到問題,原來是Power Supply掛了…
因此就這樣過完了我的上一個年假…好悲情的年假,年假沒了,錢也沒了~




好死不死,今年又要過年假了,這個星期一老婆打電話到我公司來說,"老公,家裏的電腦好像怪怪的"(我最怕聽到這樣形容詞的,就好像老人家跟醫生說身體不舒服,但又說不出來那裏有毛病…),心中又是一凜,難不成是詛咒,而且還是很準時報到的詛咒…詳細地詢問之下,不但電腦按Power沒有通電而且還有戴奧辛的味道,這時我大概知道要準備花多少錢了,不是主機板掛就是CPU掛,這次我比較不擔心Power掛了,因為上次的經驗,我上次特地花大錢買了好機絲!(主動式PFC模組化500W)

後來回到家中二話不說直接先把電腦解體(有點像是解剖命案屍體找兇手的感覺),經過單獨Power Supply測試,果然頭好壯壯一如往常,把主機板拆下來仔細檢查,真的在1394跳腳附近燒黑了一塊,還有焦黑後的灰燼…心中盤算著如果只有主機板自爆不傷及無辜最好,如果不小心波及其他至親的話,…那就完蛋了,年終獎金又要準備直接從手中離去。

接下來這幾天就開始進去無止盡的循環,先買了主機板替換測試,很興奮地把AMD 64 X2很努力地拔下來(隨著時代的進步CPU愈來愈難拆,以後386時代超級簡單的事情,沒有想到CPU一直進步,風扇的安裝卻是難如登天),再很努力地裝到新的主機板上。很高興的事出現了,終於正常聽到好久不見的"嗶"聲,真是感動莫名。

不過最難的考驗現在才開始,開機之後一直有一個問題,就是原來的SATA 250G系統碟看不到,明明就有接著電源及訊號線但是在BIOS中就是沒有,不管三七二十一,先開始把WindowsXP裝起來再說,就這樣經過了一兩個小時之後系統裝完了之後關機,開始查看找不到HD的問題,把線路重新拔插之後,確定都沒有問題了,再重新按下Power,結果…大家應該猜得到,又回到了原點…此時腦袋一片空白,突然有一種很熟悉的感覺(數年前跑到香港去考第一次CCIE Lab時,遇到問題解不出來時,就是這種感覺!),有點不知道明天在那裡,有點不知道下一步該如何,更有一種手軟無力感(可能吸了太多戴奧辛,武俠小說盛傳的七筋軟骨散效力大該就是如此,哈)。

此時開始心中問號無限 ????? ~ ?????

在無止盡的失望中開始把東西西一個個下線進行測試,下到最後什麼都沒有了還是無效? 這就更奇怪了,明明不是只有HD的問題嗎?
怎麼把HD都拔掉了,還是又回到沒有更換主機板前的狀況一樣????

此時有一個衝動,很想從10樓把電腦丟下去 !@#$%^&* 這時小兒子出現,說了一句話"爸爸,你電腦壞了喔"
我運氣了一會,把EQ提至頂點,甚至高於頭頂之後,冷冷地回應"嗯!有事去找媽媽,爸爸在忙!"
敬告各位小朋友在爸爸情緒不好的時候不要去打擾,免得成為出氣筒…我想很多受虐兒有時是突發狀況的受害者,呵!

就這樣子放棄了第一階段的修復工程,把Power Supply拆了下來準備隔天拿到公司去測試,確定電源供應沒有問題再來測試其他零組件!(事發至今已經第三天...)



隔天到了公司,快速地把原有的PC Power Supply換下來,再換上家中的Power Supply,結果非常的順利完全沒有開機或電力不足瓦的現象。

至少可以去除一個可能性,沒輒了,因此上網找救星,經過許多人的經驗傳承,我發現了一個問題,開機不過電的四大原因,一個是主機板,一個是Power Supply,另外一個就是CPU及Case短路問題。

因此決定第二階段將先試著裸機測試,當天下班後,很努力地把主機板從Case拆下來,然後使用一字螺絲起子在Power跳腳那邊給它短路開機,很不幸地,仍然失敗,所有的風扇轉了不到1/10圈又停止運轉了…心中又響起小時候的國父革命十一次才成功的故事,心想國父當年真有先見之明,不但要革命還要故意失敗這麼多次好讓後世進行樣本教學!

只好換個目標找CPU下手(因為此時蹲在地板上看著這張新買來的主機板,心中很過意不去…因為很擔心它還沒有上線就要跟我再見了…),很多人有重新將CPU拆下再裝上就可以通電的情況,雖然我確定我風扇裝得很牢固,不過只好死馬當活馬醫。又很努力地好不容易小小失手只讓一邊扣架削了一層薄薄的片之後,終於把CPU拿下來,後來我發現去年上的散熱膏經過乾化之後難不成反而成為隔熱膏?因此先把原有的散熱膏先刮乾淨再重新上CPU,這次終於終於終於正常開機了。(一定要講這麼多次終於因為實在是有點不敢相信這是真的!)

好,接下來,手有點發抖(因為有一種否極泰來的感覺),先把Power Supply電源線拔掉,小心翼翼地先裝上我的PCI-E顯示卡Nvidia 8600,然後再用一字起子短路開機(仍然是裸機上線)。Great! 順利開機!!! 這是第一個成功的里程碑

開始嘗試裝上第一個SATA 250G系統碟,然後再拿著螺絲起子開機,風扇快速地轉了…不到一圈恢復靜止,接著心中響起平地一雷,感覺到夜晚竟然是如此寧靜(現在時間AM 01:10),難道過去幾天的努力是白忙了嗎?(昨晚睡覺前跟老婆說的最後一句是"明天你幫我問一下樓下修電腦的那家店檢測電腦要多少錢?",因為已經很無力,包括我的錢包也是)

此時沒有他法,只能再猜測這個系統碟真的是有問題的關係(用了電腦這麼多年,不曾因為發生HD fail而無法過電,因此從來沒有想到不過電的原因會是在HD上),只是明明之前也有接著也是可以過電的,甚至安穩地安裝完了WindowsXP…種種的不解仍然是個謎,不過我已經沒有太多時間了,明天早上還要教課,我不希望在台上胡言亂語一番誤人子弟。決定進行最後的測試,不要用這個SATA 250G HD了,嘗試接上另一個250G IDE,此時,最後的正義終於到來! 一切正常,說時遲那時快,在很短時間內我把所有該上的零組件全上了,該接的USB設備也全接了,憑著最後一著的信念賭下去,果不其然,美妙的嗶聲,可愛的BIOS畫面竟然是這麼美麗,終於找到了罪魁禍首-SATA 250G HD。

後來我仔細端詳這個HD的主機板,原來這個主機板裸露的部份上有一個小小的晶片只剩了1/3,另外2/3不知跑去那了,還露出了細細的類似銅線的電路部份,看來這幾天的努力還是有成果(原本準備如果今天還是沒結果就要投降了!)



以上是今年農曆新年前的一大驚喜,希望明年不要再來一次,不然真的會受不了(這兩年的電腦故障,歸咎原因應該還是房間的灰塵加上汐止的潮濕,尤其是最近連續的綿綿細雨,真的連人都快發霉了)。

Introducing Cisco Certified Design Expert (CCDE) Certification

Introducing Cisco Certified Design Expert (CCDE) Certification
Responding to strong customer demand to assess and recognize Sr. Level Network Architecture skills in the market, Cisco is introducing a new premiere knowledge based certification focused on Network Infrastructure Design. - The Cisco Certified Design Expert (CCDE). The CCDE is an expert-level certification with content emphasis on expertise in network architecture, which is the capstone for Cisco’s design curriculum. In addition, passing the CCDE certification demands competencies of an experienced, seasoned, networking professional with a proven ability to interface with customers at the executive-level to ensure that business requirements are incorporated into successful designs.

What is a CCDE?

The successful CCDE-certified individual must have a demonstrated an ability to analyze and develop solutions which address planning, design, integration, optimization, operations, security and on-going support focused at the infrastructure of large 1000+ node customer networks.

The CCDE certification recognizes those with expert-level knowledge and skills in Infrastructure Design. The CCDE program is parallel to the CCIE program in terms of the expertise required and certification exam difficulty. It emphasizes network design principles and architectural theory of the network infrastructure and recognizes designers with the knowledge to assess network business requirements and translate them into technical specifications for successful designs.

Why Cisco Created the CCDE Program
Cisco created the CCDE program to respond to market demand in recognizing existing senior-level Network Designers and Architects while simultaneously providing senior Operations Engineers and Support Engineers with a validated professional development path into an Architectural role.

Cisco has found that organizations employing strong Network Designers and Architects consistently develop networks that are easier to maintain and troubleshoot. Properly executed, a well-designed network infrastructure aligned with a network-centric corporate business strategy leads to greater levels of efficiency and effectiveness - as well as potential competitive advantages like increased up-time, easier troubleshooting, increased performance, and simpler enhancements.


What are the exam requirements to attain CCDE?
To attain a CCDE certification a candidate will be tasked with passing two exams; a Qualification Exam, and a Practical exam. Similar to the CCIE program, there are no prerequisites to taking the Qualification exam and it is a 2 hour multiple-choice exam available at any worldwide Pearson VUE testing center. The Qualification exam, (ADVDESIGN) 352-001, assesses fundamental knowledge of networking theories, principles, protocols and technology.

Visit the CCDE program site for more details regarding the Qualification Exam (www.cisco.com/go/ccde)

The second exam, the practical exam, is still currently in development. It will be an eight-hour, practical scenario-based exam available in late 2008. Bookmark the CCDE programs page as more details are expected to follow as the development team progresses.

The qualification exam is now available at Pearson VUE testing facilities worldwide.

How to quit your job

ITworld 1/18/2008

Emmanuel Conde, Bridge Resourcing Solutions
Take this job and shove it
I ain't working here no more
My woman done left and took all the reasons
I was working for
You better not try to stand in my way
As I'm a walking out the door.
Take this job and shove it
I ain't working here no more

Johnny Paycheck may have had good reason to be unhappy about his job when he sang this song, and you may be tempted to borrow this famous line when leaving yours, but don't.

There's a lot to consider when a CCIE feels it's time to make a career move. Typically, compensation is not the main reason. How a CCIE earns a living is as important as how much they earn. Greater technology challenges and responsibility usually drives the decision to look around. A limited career path may also be a factor. Moving up in a company is often tied to management responsibilities, but many technologists don't want to manage staff. While mentoring is attractive, the responsibility for annual reviews, budgets and morale takes all of the fun out of pushing bits and bytes.

Here are some tips for a smart search, and a healthy transition:

Keep positive
I advise anyone interviewing with a recruiter to refrain from being negative about a current employer. Negativity is a red flag, and gives me a reason to do more thorough reference checks.

Give plenty of notice
Happy or not, you owe your employer notice of your intention to leave. In the US, a two week notice is standard. 30 days is common in the UK. Often a CCIE's responsibilities for a project or critical deliverable may necessitate a longer notice and when an employee has the courtesy to note this in their resignation, it is usually appreciated. However, be careful if your next employer is pushing you hard to wrap things up with your current employer earlier than you are comfortable with. Burning bridges is dangerous. The CCIE community is small. Your paths will cross again. Be polite and do the right thing.

Well that foreman, he's a regular dog
The line boss, he's a fool
Got a brand new flat-top haircut
Lord, he thinks he's cool
One of these days, I'm gonna blow my top
And that sucker, he's gonna pay
Lord I can't wait to see their faces
When I get up the nerve to say

Be polite
Never allow yourself to quit in anger or frustration. Collect your thoughts. A simple resignation expresses an appreciation for the responsibilities given, makes a statement about the decision to make a career move, and the date intended for separation. Avoid a long, drawn-out process. Remain in control of the exit and prevent personal feelings from entering the process. I have seen tears, shouting matches, and tire slashing. Quitting is hard especially if you've been working with the same team for years. Feelings that you are letting down the team by leaving are real.

What to say
Here's an example: "Tom, I appreciate the opportunity you have given me over the past few years. I have made a decision to move on and would like to ensure we have an orderly transition of my responsibilities. It is my intention to resign my position effective January 23rd, 2008."

How to say it
Deliver your resignation in person and face your boss in a private area. Ask them to give you some time on their schedule to discuss a personal matter. Most managers will be pretty busy and will have to add you to their calendar if they think the discussion is a business matter. Let them know it is important and of a personal nature. Don't dwell on negative discussions and practice what you are going to say to avoid blurting out anything you might regret later. Hand them your letter of resignation and give them a moment to take it in. Let them know it was not an easy decision to make and offer to assist in your transition.

Final advice
Leave on a good note and never say, "Take this job and shove it"!
