Fuck

"Fuck" is not an offensive word so long as you know how to use it wisely. I use it more than 10 times a day.

Some people not even worth to be fucked or worth to fuck.  These people are all around at our workplace. Worth to fuck or worth to be fucked, that's the question I always ask.

CPEs

In just half year, I've got 54 CPEs. It is not difficult for me to complete the remaining 66 CPEs in the coming two and a half years. So as I always say, the CPE mandate should not be seen as a hardship, rather it is a drive to excel ourselves to new insight.

IGMP

Not more crazy complaint on this - IGMP traffic inside a network segment is not attack traffic. It is a form of legitimate traffic.

Goodbye Sendmail !

Goodbye Sendmail. You had been with me since 1998. Thanks for serving me for the past 18 years.  

Your rock stable performance should surprise the Internet technical community.  However, I need something more versatile, administrator-friendly and easy to debug.

Bluetooth Tethering

I suppose all people who have multiple smartphones and tablets know how to do Bluetooth tethering.  This is important because WiFi tethering can not be done in some prepaid data cards.

misuse of high gain antennas


I want to kill myself for making a silly mistake. My ASUS router supports dual bands and 802.11ac. However, I use 8 dBi high gain antennas which suit the 2.4 GHz band only. While the signal strength in the garbage 2.4 GHz band is boosted to - 30 dBm, the 5 GHz signal strength is weakened significantly. That is why all my 802.11ac client devices perform poorly. I promise myself not to commit such mistake in future.

大件事,有重要資料存放於 encrypted notepad, 但忘記刷卡解鎖模式。記密碼、記 PIN、 記模式等太煩了,莫非所有涉及加密嘅應用程式都要用指紋解鎖或現創科局長所用嘅口水解鎖嗎?

IPv6 Forever

PCCW offers me a /56 prefix. At first, I thought it was /64 only. A bit of surprise. All my home PCs arenow  riding on IPv6 and also smartphones if the connection is via my home WiFi. From now on, I am accessing all major big websites (Google, Gmail, Yahoo, Bing, Youtube, Facebook etc) with IPv6 having IPv4 as fallback. Anyway, this comes to me a bit late.

Stupid remarks of 盧寵茂

I am  very pleased to spread the leaked out recording of the remarks by HKU Council Member盧寵茂 at the Council Meeting on 29 September.  Let all HK people judge how stupid 盧寵茂 is. Here it is.

"盧寵茂:
And in the personal point of view that he is a good guy as many of the members have said. He is a good man. He has been working for the University for so long. This is the first impression for me that I should support him. But after looking at this and especially after the incident in July, I have some reservation. It is about his qualification. Professor CHEN has a very detailed analysis on the publication. You can look at it, for the last 15 years, he has produced less than 5 items output including factor and article, less than 5 a year and in some years for example, in 2008, he has produced only 1 item, 2011, 1 item only.
(正如許多校委所言,我個人認為他是一個好人。他在港大工作多年。我第一個念頭是,我應該支持他。然而當我仔細考量,尤其是七月事件(學生衝擊校委會議)發生後,我有些保留。關於其資格,陳(坤耀)教授就其學術文章作過詳細分析。過去十五年,他出產少於五篇學術文獻,每年少於五篇,他分別於2008年和2011年各出產一篇文章而已。)

I know the number, quantity, is not the absolute measure, you have to see the quality as well. If I have an assistant professor with this kind of output, I will be very concerned, I would really say, hey, how can you reach the bar of the notion within the university, very strict criteria 4 + 4 for practical, 3 + 3 for non-practical, for promotion either up or out from an assistant professor to an associate professor. If my assistant professor give me a CV of 1 output per year, I would say, you are in trouble. In 6 years or in 8 years time, how many publications did you have in your CV? You can’t reach that bar.
(我明白產量並非絕對標準,也視乎質素。若然我屬下的助理教授只有這樣的產量,我會非常憂慮。我會說,你怎能符合港大"四加四"和"三加三"晉升為副教授的嚴謹要求? 若果我的助理教授的履歷只有每年一篇文獻,我會說,你惹麻煩了,在六至八年內你會有多少篇文獻? 你並不達標。)

But on that event, on that night we have been in the storm of Council meeting and subsequently my injury. And after the event, I didn't really see him showing any sympathy for the Council members, and in particular, I use myself as an example. I am a staff elected by all the other staff to take part. And i sustained and injured. From all the opinion that he has expressed, actually he's still putting the blame on the Council, he has never...i'm not saying I need his sympathy. But as a staff, i really feel if you are PVC (staffing) and if a staff member had an injury during an event like this, should you just keep on saying it's the Council's fault, that means it's my fault as well? So in a way he's telling the public, he's speaking out in public, including his 香港家書, that the fault remains in the Council...the suffering i encountered. That is my reserve.
(然而,在校委會會議掀起風暴那一夜我受了傷,此後我看不到陳文敏對任何校委致以慰問。以我本人為例,我是員工選出的校委,我緊守崗位並受傷。但他對外發表意見,只是怪責校委。我不是說我需要他慰問,但作為掌管學術及人事的副校,若有同事在這種場合受傷,你應否不斷強調這是校委會的錯,即是我也錯了?他在香港家書等公開言論均指錯在校委會...我所受的苦。這是我有保留的原因。)

But when I fell, all these people...I am not saying only the students, I know there are people outside the University, there is no doubt that the student lead the crowd in when I have this meeting. I was accused in so many media, so many articles, pictures to say that I am an actor, 插水, alright. I really feel very bad, I didn’t complain eventually and even when I was in the hospital and I talked to the media with my occupation in charge that I will kindly accept, "我唔追究D 學生". That’s my true belief because I feel very sad if those people in the room and outside were our students, I really feel ashamed. We have not done our duty well.
(然而當我跌倒,這些人...不只是學生,還有校外人士,牽頭闖進來的無疑是學生。在很多傳媒文章和相片,我被指控是演員、「插水」。我很難過,卻依然沒投訴,在醫院對傳媒也說我會接受:「我唔追究啲學生」。這是我的信念,我難過的是,若果會議聽內外的是我們的學生,我會覺得羞愧,因我們沒盡責(教好學生)。)

And in contrast, he put the blame into the Council members and including me as a staff member. I am really terrified that someone with this kind of... i don't want to extrapolate but I felt if someone ... i would say he's putting his political inclination into the university. Because of the difference in political opinions he may think that I am here to represent CY. I can tell you I am not a 梁粉. I came in with support of the staff members. I've never talked to CY. CY has never talked to me about this. but it seems that everybody there including Johannes Chan has labelled me as a 梁粉...and whatever I did, whatever I suffered, I deserved it.
(反之,他責怪校委,包括我作為職員。我感到震驚...我不想揣測但我感到...我會說他把政治取向帶進港大...由於政見不同,他可能認為我在此是代表梁振英,我可以對你說,我不是"梁粉"。我是基於同事的支持加入校委。我沒與梁振英說過話,梁振英也從對我談及此事。似乎所有人包括陳文敏已經標籤我做"梁粉"...無論我做過甚麼,受了甚麼苦,都是我"抵死"。)

馬斐森:
There were 4 academic members on the Search Committee. I was qualified to make academic judgments. I have a lot of experience of making these judgments. There were 3 other academic members of the committee. So there were 4 ppl, 3 of them are not here to represent their views, so my job as a chairman is to represent their views. Academic credentials were considered, and were considered suitable. Council members may disagree. But I am not going to go back from the judgement made by the Search Committee.
(物色委員會有四名學者(包括他本人)。我有資格作學術判斷,而且經驗豐富。另外三人現不在席,我作為委員會主席有責任代為表達。我們曾經考慮申請人的學術資歷,認為合適。可能有校委不同意,但我不會重新審視物色委員會的決定。)

As to a comment to the number of papers he published, I think it’s utterly irrelevant. There’s no job description that says you could have published certain number of papers or you’re not qualified for this role. The absolute number of papers published are not...quality and you can’t transfer from medicine into law because the publication requirements are different. So frankly the number of paper he published in the last 15 years I think is irrelevant.
(至於對文獻產量的意見,我認為完全不相關。招聘條件並無指明你必須出產一定數量的文章否則就不合資格。文獻數量並不...質素。你也不能把醫學的學術要求轉移至法律,因兩者出產文獻的要求不同。老實說,我認為過去十五年他的文獻數量並不相關。)

So my comment on that is I think you’ve taken things very personally, and I think we should keep things to factual discussion, and the purpose of the candidate. There’s no requirement in the job description for the candidate to express sympathy otherwise for anybody who is injured. I think you are putting post-event facts into this particular context, so the … I can’t speak for the Search Committee, Search Committee hasn’t met since 27 May, I can only speak as a Council Member, the events that happened since the Search Committee’s paper was written on 27 May, there have been many things written and said, a lot of opinions, I prefer to stick to the facts. And the facts that the Committee has to consider were the qualification and suitability for the post. I’ve already said at the start of the meeting that it’s my view that whilst none of the outcomes are attractive, to my mind, there will be less damage done for the University by the acceptance of the nomination and become a......projection.
(我認為你(盧寵茂)摻雜很多個人情感。我們的討論應基於事實和招聘目的。招聘條件並無要求申請人對任何傷者致以慰問。你把做完決定之後發生的事都考慮在內。我不能代表物色委員會發言,他們在五月廿七日之後未曾碰面。我只能以校委身份發言,那天之後發生了很多事情,傳媒寫了很多東西,有很多意見,我寧可聚焦在事實之上。事實是物色委員會已考慮此職位的資格和合適與否。我在會議開首已指出,即使所有結果(接受,否決或押後任命)都不太吸引,對我來說,接受物色委員會的推薦將對港大做成較少傷害。)

time belongs to the Earth, not technology !

Regarding the retention of leap second in UTC, I have no hope some concrete plans will emerge in 2023 leading to a future-proof reference time-scale. Assuming scientists and engineers are smart enough to accomplish their task, there is a need to allow 10 years for the transition. That is to say, leap second will continue to stay with us for at least 18 more years.

My view is that it is a waste of time to continue studies on this issue.  From 2000 to 2023, 23 years would have been used up.   My advice to scientists and engineers is given below:

"Time belongs to the Earth, not technology (時間是屬於地球的,而不是屬於科技的)"

leap second till 2023

Great news. ITU has just announced that the leap second will continue to be used until 2023 pending for a final decision. Between 2015 and 2023, scientists and engineers should fully study all possible technical options leading to a future-proof reference time-scale.

More recording leaked out.

Yes, more recording leaks out.  This time,  it is placed on a Taiwan  discussion group.   Nothing HK court can do.  Applaud !! 

"台灣一網上討論區晚上有人上載一段懷疑是港大校委王䓪鳴否決陳文敏任副校的會議發言錄音和文字紀錄,全文轉載如下(中文譯本取自來源網站):

Thank you Chairman. I just want to make a few comments, but the comments...when I make this comment I understand, I totally understand my duty as a member of the Council, particularly in terms of the appointment of senior executive in this Council. I understand it well and I understand the duty. And to me, there is no emotion in that. What I said later is something that I really give a lot of thought into it. I know this candidate very well, and in fact we were in the same class when we were in LSE, so I know the candidate well. It’s not that I don’t understand him, I don’t know him, and I read the paper and every piece of paper on my table, and I exercise my independent thinking without an
ybody intervening. With the biggest interest of the University, wide and long of the University, and before I make a comment, so I know what I am doing.

謝謝主席。我只要說一點意見。當我發表這些意見時,我完全了解我身為校務委員會一員的責任,特別是委員會委任資深行政人員上,我深切了解,也明白責任重大。對我來說,這沒有摻雜感情因素,我等等要說的是經深思熟慮。我跟這位候選人很熟,事實上我們在倫敦政經學院是同學,所以我跟他很熟。並不是我不了解他、我不認識他,而且我讀了我桌上每一份文件,在發言前,我經過獨立思考、未受外力影響,並考量大學最大利益,更寬廣和長遠的未來,所以,我知道我在做什麼。

In the last two years or so, this University just like Hong Kong, has been undergoing quite a bumpy journey, in a sense there’s so many things happening in Hong Kong. Started from the University, on the 818 visit of Li Keqiang and also the Occupy Central thing, the donation issue, and recently about this appointment of this Vice President and PVC. In fact the last two years and a half is pretty sickening in the sense, you can see that so many discussion, division, particularly and entirely divided you know, the community. And I can understand, I mean, University as part of the wider Hong Kong community that reflect whatever happened in Hong Kong in the University, I can understand, but what bother me a lot is about this division, now the problem of the division is that we continue to divide the University. I don’t talk about Hong Kong, just about this University. It really, I think to me, is becoming a distraction of the University and it prevents the University actually to look longer term. In the last two years, I’ve been sitting in this Council every month, even more work than my own board meeting, but we never have a chance to talk about what mixed in this University. If we ever even think of any opportunities that we should grab and let this University shine and glow, I’ve been patiently waiting, you know, the new VC coming to this University with a hope that we have a smooth strategy of development, no time, no discussions, everything has been pre-occupied and dominated by this sided political issue, the issues that are so d
ivided in the community. And I am sick of it.

這所大學在過去2年,就像香港一樣,經歷一段顛簸的旅程,香港發生了太多事。從818李克強來學校訪問開始,其後的佔領中環、捐款議題,和最近這個副校長的委任。事實上這2年半讓人滿難過的,你可以看到許多討論、分裂、讓社會完全分裂。我能了解,我的意思是,作為香港社會一部份,香港發生什麼事都會反映在大學裡,我了解。但非常困擾我的是這種分裂,分裂的問題也持續造成大學分裂,我講的不是香港社會,是這間大學。對我而言,它真的分散了大學注意力,也讓大學無法把眼光放遠。在最近兩年,我每個月來開這委員會的會議,甚至比我自己的董事會花更多精力,但我們從來沒有機會好好談談,這間大學裡摻雜了什麼。如果我們曾思考,是否有什麼應該好好把握的機會,讓這間大學發光發亮,我一直耐心等待,希望新副校長到任後,能讓我們有一套平穩發展的策略。沒有時間、沒有討論,每件事都被枝微末節的政治議題佔據、主導,每個議題都太分裂社會,而我實在受夠了。

And then when I think of this appointment, I give a pause into looking into whether this candidate would further divide the University, or unite the University. I asked this question because I want to see this unity, so that we’re able to see this University continue to glow. Because of the potential controversy of this candidate, I don’t say whether, you know, the candidate is wrong or why we can bring this up, but there is a potential controversy, it exists whether you, whatever position you… whether you are on yellow camp or the blue
camp, I don’t care, but the potential controversy exists. And because of a strong political position of this candidate, and I do not have enough confidence that this candidate would probably help to unite, but on the contrary, he probably would further divide. Now this is a senior executive position that’s on academic staffing and resources, I’ve been a chair of HRPC for several years, and I think that this is important that we look for person… I think in a lot of cases during my career to appoint a lot of senior executives, persons can be qualified but may not be suitable. I know this candidate well, he’s a good gentleman, but sometimes for a lot of other reasons, he may not be totally s
uitable. And I have to say, because of the controversy that exists, because of his strong political position, because of the potential risk of further divide the community, I have to say I do not have enough confidence to accept this recommendation. And I want the candidate, at least, the future PVC or the Vice President, must be able to unite and must not politicize the working place that he is working in. So on that basis, Chairman, I would suggest that we go for another search and I cannot accept the recommendation as proposed. Thank you.

而當我思考這個委任,我停下來審視這個候選人會不會進一步分裂這所大學,或讓它團結。我這樣問因為我想看到團結,我們才能看到大學持續發光。由於這候選人潛在的爭議,我不是說他是錯的人或者我們為什麼提出這樣的議題,因為存在潛在爭議,無論你在什麼職位,無論你屬於黃絲帶或藍絲帶陣營,我不管,但潛在爭議就是存在。因為候選人強烈的政治立場,我沒有信心他能夠有助團結,相反地,他可能帶來進一步分裂。現在這是一個掌管人力資源的資深行政職務。我任職「人力資源政策委員會」主席數年,在職業生涯中多次遇上委任資深行政職務的案件,我認為尋覓人選時很重要的是,有的人可能合格,但不一定合適。我認識這名候選人,他是名君子,但有時因為各種原因,他可能不完全合
適。我必須說,因為爭議的存在、因為他強烈的政治立場、因為存有進一步分裂社會的潛在危險,我必須說我沒有足夠的信心接受這個人選。我希望的候選人,至少未來的副校長,必須要能促成團結,必須不讓他的工作場域政治化。所以主席,基於這些理由,我建議我們另覓人選,我不能接受這個推薦人選,謝謝。"

Another piece of fucking remark at the HKU Council Meeting on 29 Sept

Another piece of fucking remark at the HKU Council Meeting on 29 Sept:

"Chairman, I have been a corporate CEO and employer for over 30 years, and I have interviewed and hired hundreds of people in the past. But never in my life have I encountered a candidate who will overtly and recklessly discuss his or her potential employment at any stage of the recruitment process. This in fact is already in breach of confidentiality.
It is most unfortunate that the candidate recommended by the University Search Committee has never been tabled at this Council for deliberation. In our view we are actually doing it according to procedures.

I am in support of press freedom and also in sympathy with the candidate who defended himself against the criticism of some media. But apparently he has gone too far, to create controversy and use external and internal forces, directly or indirectly to lobby, pre-claim, coerce, intimidate, fabricate and sometimes even threaten Council members to approve his appointment. I myself was a victim on February 12th this year when I was accused by a local newspaper for stalling his appointment at this Council. I then have to issue a public statement to clarify that the Council has not even started to discuss this appointment. This is just one incidence among many, and to me, all these tactics in fact are interference in the University affairs at the highest level.

As members of the Council, and also trustee of the University, we are professionals with our independent judgment and ethics. We do our assessment based on the…… interests of HKU and the community at large. Given that position of the pro-vice-chancellor is responsible for academic recruitment and resources, the pro-vice-chancellor should be a role model for all, staff and students included. So I have strong reservation about the recommended candidate's integrity. And I would not accept the recommendation.


Thank you."
