Another 'place the hands in' a hand drier - far superior than conventional air blowers

Why are conventional hand driers still being made? (A rhetoric question really). Remember my Dyson Airblade review. I found another hand drier of the same kind. These are so much superior to the convenient ones. They dry hands faster and there is no need to press a button to start them (although even some conventional ones have sensors).

Confucius said 'By nature men are similar; by practice men are wide apart'. The truth of PIM

One of the many Confucian quotes is 'By nature men are similar; by practice men are wide apart'. Thinking of it, it can be applied directly to PIM. We all manage information, although we all do it differently in practice

However, Confucius did not have the PIM in mind when writing the Analects. This phrase has a wider view of the word in which all humans are equal when born. It is the learning and the environment that shape us. There are different views of this quote by later neo-Confucionists (especially Mencius and Xunzi). However they explain the quote, it can be interpreted in many contexts. Here's how some scholars see it:

Esmond D. Smith, Johnson & Wales University

"One of the distinctive features of Confucius's teaching is the confidence that he expressed that human beings are essentially alike by nature. Confucius thought that the important differences in human beings are determined by environment and education, by the habits and preferences they develop and the lives they lead. For this reason Confucius put great emphasis on learning. But because he saw people as constantly changing and growing, his teaching was not the same for everyone."

Wikipedia explains Mencius' and Xunzi's views of human nature, focusing on the good and evil

"Confucius never stated whether man was born good or evil, noting that 'By nature men are similar; by practice men are wide apart' —implying that whether good or bad, Confucius must have perceived all men to be born with intrinsic similarities, but that man is conditioned and influenced by study and practise. Xunzi's opinion is that men originally just want what they instinctively want despite positive or negative results it may bring, so cultivation is needed. In Mencius' view, all men are born to share goodness such as compassion and good heart, although they may become wicked. The Three Character Classic begins with "People at birth are naturally good (kind-hearted)", which stems from Mencius' idea. All the views eventually lead to recognize the importance of human education and cultivation."

Sanderson Beck, Confucius, Mencius and Xun-zi, CHINA, KOREA & JAPAN to 1800

"Confucius believed that people were similar by nature but became different by practice, and thus there are some one can join in study, others one can join in progress along the way, others again beside whom one can take one's stand, and finally some whom one can join in counsel."

Edward Gilman Slingerland, Confucius, p. 200, Hackett Publishing, 2003

"17.2 The Master said, “By nature people are similar; they diverge as the result of practice."
Although not a primary concern for Confucius, the topic of human nature (xing 12) became a central focus of debate in later Confucianism. Mencius famously declared that “human nature is good (shan §),” and repeatedly defended this claim against his opponents. Xunzi chose human nature as the center of his confrontation with Mencius, famously entitling one of his chapters, “Human Nature Is Bad.” The character of human nature was a topic of lively debate throughout pre-Tang Confucian thought, with various positions—it is good; it is bad; it is neutral; it is mixed (some people are born good, others bad)—all being defended as expressions of Confucius’ original view. The lack of theoretical consistency in the Analcts makes it possible to argue for any of these positions. Passages that emphasize the importance of native substance (zhi Q) (3.4, 3.8) sometimes seem to imply that at least some people are born with the “stuff” of virtue that merely needs to be refined into full Goodness; passages such as 2.9, 5.9, ll.4, 16.9, and 17.3 imply that some exceptional sages (such as Yan Hui) are bom fully good, while 5.10 and 17.3 similarly imply that some are born hopelessly flawed. The general tenor of the Analcts, however, seems to be summed up fairly well here in 17.2: all people, even non-Chinese barbarians, are bom with more or less similar basic stuff, and it is the quality of the tradition into which they are socialized—the consequences of "practice" (xi ’§)—that really makes the difference."

"Information about me" and "information for me" - what is personal in PIM

There is a nice blog post by David Karger about information "about me" and information "for me".

"About me" is information about us and we might have control over it (e.g. our Facebook, Twitter streams) or might not (e.g. information other people post about us on-line or in public space).
"For me" is information that we can manage, it fulfils our needs and it might be about us (eg. appointments in our calendars) or not (my mp3 files in our music library).

I just had a discussion on this issue with Alan when I remembered this post. David pretty much covers it all, but if focusing on the management, several instances between "information about me" and "information for me" in the social context come up. With the social context I mean sharing personal information as defined by Jones [1]. 

(I) Controlled or owned by me
(II) About me without my control over it e.g. bank records
(III) Directed toward me e.g. phone calls
(IV) Sent or posted by me for others e.g. emails, web pages
(V) Experienced by me e.g. a book in the library and
(VI) Relevant to me but I haven't discovered it yet

If we stick to these 6 types of personal information, "about me" strictly falls into the group (II) while "for me" in the group (I). Although (I), (III), (IV), (V) and even (VI) can or not be about me, while (II) is about me only. Examples of info about me (I) my bank statement I keep in a folder, (III) a sent passport by the government to my home address, (IV) photos about me I post on-line, (V) an autobiography book I have(n't) authored in the library and (VI) something about me I don't know yet. Likewise the are examples of information not about me under each of these categories.

So what are these in-between instances of personal information in the social context (for others to consume) I mentioned before?

1. Information that we have (some) control over it - we manage it. This can be either information about me and/or information for me (which in the social context could also reveal a lot about me as well). There are three different types of such information:

  • Information that we manage primarily for ourselves, but also make it publicly available for others to consume (this information is not necessarily about us but can reveal a lot if information about us). Examples include Delicious, Mendeley, Amazon wish list, etc.
  • Information that we usually manage for ourselves only, but individual items or even collections are shared with known end-users (information could be about us or not). Examples are Google Docs, Dropbox, Sharepoint, etc. (if publicly available can also fall under previous group).
  • Information that we publish (sometimes even manage in categories) with the intention for others to consume and is in general about us (but not only). This includes blogs, social networks, personal web pages, etc.

2. Information that we have no control over it (or maybe, if we stop socializing :)).

  • Information that we do not publish but is about us and we have not control over it such as our photos online posted by other people (company, friends ...).

This second one (2.) is problematic. By definition, this is still personal information from the (II), although Jones mentions only medical, school, police, justice, bank or state records about us, which are usually not disclosed to the general public. We in general trust these institutions to take good care of information "about me". However, when information "about me" gets disclosed. we have no control over it (just imagine our credit card details sold on the black market or just the photo of us in the newspaper). Potentially can such disclosure cause real harm, but most of the time it might be just annoying (our friend uploading photos of our holidays, parties, etc.).

While the first one (1.) is still information "for me" even though we make it available to others as well. But it can be also information "about me" either directly (posting our photo on Flicker) or indirectly (posting our reading taste on Amazon wish list or hobbies on Delicious). Karger proposes a new term

  • End User Information Management

which better captures who is managing information - but IT DOESN'T equal to information "for me" only as we could manage it for others as well. This end user information management could be done to satisfy our needs (e.g. the need or better the wish to post holiday photos) or needs of others (e.g. our parents and friends who wish to see these photos). David for example mentions his management of music (old style PIM) which hopefully satisfies needs of others when he's DJing. While the second in general (2.) satisfies just the needs of others!

To distinguish the type of management maybe these two axes should be considered:

  • who is managing personal information (we or others) and
  • whose needs this management satisfies (our needs, also needs of other or just needs of others).

And we would end up with six different categories of information like this (while each information could span over several cells):

Management of info \ Satisfying our needs our and/or needs of others needs of others
by me

by others

Each category of personal information should be then be weighted against privacy, policy controls, ethics and possibly other issues concerning the information in question. So there are not only "about me" and "for me". The issue is definitely more complex.

Bash - looping or capturing a multiple line command output

I tried to loop a command which returns a multi-line result in a bash script. The problem was that the quoted command returned ONE line instead of each line separately. So I ended with one line consisted of multi-line result while I was expecting that the quotes would preserve the spacing. Without quotes I got each "word" in a new line while I was expecting everything in one line (without quotes should replace multiple blanks, tabs and newlines with a single space). Here is the "faulty" script:

#for line in `ls -l`
#for line in $(ls -l)
for line in "$(ls -l)" 
    echo $line"XXX"    

Not quite sure if this is due to OS X (or BSD) environment but I got around it by piping the command to the while loop:

(ls -l) | while read line
     echo $line"xxx"


while read line; do
    echo $line"xxx"
done < <(ls -l)

DIY simple cheap bedside garment rack fixed on the wall

I made this two simple garment rack to hang cloths in our room. They're located on both sides of the bed. The idea was not to have anything on cycles on the floor and in a way.


  • round iron bars 6mm radius (used for fencing and found at the fencing workshop as leftover)
  • 2 zinc plate brackets (found at ScrewFix
  • Metalic silver paint in spray container
  • Welding machine with all needed equipment (if you don't own one and don't know how to weld, the solution is to ask at the local workshop as this job took less than 5 minutes).
