"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.



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.



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.

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.

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.

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.

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.

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.

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.

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.

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.

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 !! 


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.


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.


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.



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."


This was the remark by Arthur Li.

李國璋的說話 : 

So from that point of view, I have no worry in that he is dean, my main worry on academic side was that he has no higher degree equal to a PhD or an MD or LLD, now you may say in law is not necessary. Well, if it is not necessary, why is such a degree there in the first place? And when you look at the other referee professors, they all got LLDs. Therefore, either he hasn’t tried or he is too busy or he doesn’t think it is important, but if that’s the case he will be devaluated maybe of the lecturers, professors who have got PhDs, who have gone through the rigours of academic pursues. Now, can you, can someone be in charge of promotion of another person who actually has not gone through the same rigours as that other person and give an honest independent objective view? And I would put my question here is that, I do have my doubt about this.

However, I do have some worries that I feel I should articulate, the Dean, the vice chancellor, in those days, were elected by the Faculty. So all you have to do is to be a nice guy to everyone, and I think Johannes Chan is a very nice guy. And at this point, I’d like to declare my interest; there was one of the referees which is my cousin. And my cousin has already said he’s a very very nice guy.

The second thing I’d like to bring up is that, we’ve been said that we’ve been under a lot of pressure form the liaison office, from the Chief Executive, and I’d like to say very categorically I have not been under any pressure. It has been said that the left-wing press, 文匯報、大公報 have been running hundreds of articles against this candidate. And quite honestly, I don’t read 文匯報 or 大公報, and I think most people in Hong Kong do not read 文匯報 or 大公報. Relatively most people take a negative view, the more they say about something, the more we feel anti whatever they say. However, on the other side, it’s that the political parties are very well organized, very well informed, very well…how would I say… very keen to push this candidate by, as Leonie said, by intimidation, by failing our council meeting, by having concern groups and all these threatening JRs and everything. But I just wonder why is these political parties so keen on this candidate, is it, you know, in the Mainland university, they have 黨委書記. Do they want a 黨委書記 at Hong Kong U? Is he a 黨委書記, is he put in here as a 黨委書記? So I don’t know, forgetting about the politics, all these things made me feel very uncomfortable and very uneasy with this candidate.
