Professional Communication

Just a quick summary on the useful things that I’ve learnt during the 3 hours of Professional Communication lesson today (mostly from the tutorial session). D:

Most of the time, we thought that we know ourselves better than anyone else. But when we are asked of what strength we have, we could turn speechless for at least a few seconds. As Asian, I’m not being brought up in a culture that I can pompously speak about my strengths. I have to think twice or more for an (general) adjective to describe myself so that the person will not sneer behind me. : /

During interview or when writing resume, it is important to be mindful of the adjectives chosen. There are perceptions sometimes, without realizing that ourselves.

When you said you are confident, they may think you are arrogant. More examples below:

Persistent -> stubborn?

easy-going -> not serious?

creative -> not realistic (opps, that’s true)

communicative -> talkative?

meticulous -> calculative

leadership -> ambitious (mindful!)

Certain words like leadership and having a vision may not be suitable when you are applying for an entry job. It is true because those people interviewing you are someone more superior than you, and when you say you can lead well or you have a vision, it somehow challenges their authorities.

Next, to handle complaint letters, there are a few things to keep in mind:

  1. consider impact on readers – do not make them feel bad (like “Our company has taken serious actions against the staff”, will the reader feel guilty?) put yourself in the reader’s shoes.
  2. use POSITIVE approach – Never ever use the word NOT because it brings negative energy in your letter. “You are not, we cannot, it is not, etc)
  3. avoid using clichés – it is not something that can be overused and it has to be used carefully.
  4. think for reader’s benefits – what can the reader benefit from your suggestion/action?

Important things in reply to a complaint letter is to

  1. acknowledge that you’ve understand the problem and not blaming anyone!
  2. provide solutions/suggestions/advice (based on your expertise)
  3. build goodwill 🙂

Let’s be mindful over formal letters!  Wait, reread, revise, send.

SD Card Format Successfully

Out of many suggestions found over the web and by fellow Raspberry-Enthusiasts in the Official Forum here, I finally found a solution to my SD Card Write-protected problem as mentioned here.

I intended to use my camera to format the card but I didn’t try it. Also, I didn’t have an external card reader. Thankfully, my friend, Alex, lent me his external SD card right after i posted that on Facebook. 😡 So kind!

Finally, on this blue Monday, I plugged in the SD card into the reader and plugged the reader into my laptop. I run SDFormatter, configure quick settings and click “Format”. There were no “write protected” words appear anymore. YESH! So the process went well and I transferred the extracted NOOBS files into the SD card.

 

Now lets wait for me to get a HDMI cable. 😉

Btw, I met up with my pretty professor on Friday and we discuss further on the ideas. 🙂

My direction becomes clearer:

– automated pill dispenser & reminder system

– can help to reduce the burden of caregivers / nurses

– panel installed in a ward to check patient’s profile and dispense the medicine automatically.

Engineer to Doctor

I was researching for automatic Pill Dispenser when I came across this guy, John Kirby. Read this:

I had the original idea of how the machine would work and it was my patent, but it was a joint effort getting it to work in a saleable form. It was 3 years of very hard work. I had originally studied heavy electrical engineering before changing over to Medical School and qualifying as a Medical Doctor in 1968. In fact I was Senior House (Casualty) Officer (A&E or ER) in 1970 at North Manchester General Hospital when I filed the patent. I must have been the only hospital doctor in Britain with an oscilloscope, a soldering iron and a drawing board in his room in the Doctors’ Residence. The housekeepers were bemused by all the wires. Frank originally trained as a Banker but quit to take a job with a local electronics firm during the development. He died in 1987, a terrible loss. [Extract from personal communication received in March 2010 from John Kirby.]

 

My Prof told us today that there are 4 things that can’t be recovered:

1. The stone after shot
2. The word after pronounced
3. The occasion after lost
4. The time after gone

Okay, treasure my time and stop Facebooking! 😡

Hey Raspberry

So i’ve got my new Raspberry Pi for ages and had problem with my SD card while trying to write NOOBS into it. Last night, I decided to try writing raw Image, Raspbian, into it.

It took me over night to download it (as i fell asleep) and this morning I’ve forgotten how did I verify the image for the last time. So just a note to myself, here’re the simple steps. (I’m using Window 7)

1. Download sha1sum.exe from Here

2. Run command prompt (cmd)

3. Drag the sha1sum.exe file into the command prompt. It will show a path to it.

4. Put a space.

5. Drag the raw image ZIPPED file into command prompt. (Don’t extract yet because there is no point of extracting a corrupt file)

6. Compare the hash generated with the one provided on the website. (for my Raspbian, f072b87a8a832004973db4f5e1edb863ed27507b)

7. If it is the same, then you have downloaded it successfully! If it is not, redownload again.

Following through the rest of the guide here, I come to a dead end again. There you go, write protected. : /

Web Application Lesson 1

So i have been hearing bad experiences from seniors about this particular module offered to the final year student, Web Design and Application. It was said to be a time-consuming module and the professor has a high expectation on the students.

However I was kind of shocked when the professor actually is a very friendly and helpful person. Perhaps they were talking about some other professors?

Anyway, I installed XAMPP on my Window 7 today. Faced some problems that I am going to note them down.

For Windows:

1. Download XAMPP Portable Lite 1.8.3 PHP 5.5 ZIP file from here.

2. Extract it and move the files to Desktop.

3. Double-click on setup_xampp window batch file. Wait for it to initialize and complete.

4. Run xampp-control application.

5. Start Apache and MySQL. I’ve got errors while starting them!! >> what I did to solve them

– Port 80 in used by system >> change to Port 8000 instead (At Apache, click on “config”>httpd.conf, search for “Listen 80”, change it to “Listen 8000”, save.)

– Apache stopped unexpectedly. >> I stopped MySQL service under Administrative Tool>Service but it doesn’t help. Check for other application that might be using Port 80 (e.g Dreamweaver) but I couldn’t find anything (in fact, I don’t know what else).

– MySQL path in used >> Uninstall the previously installed MySQL.

Finally, I stopped Web Deployment Agent Service and changed it to “Manual start”. Only then I could start MySQL on XAMPP.

The professor said, the best way of learning is to be active and engaged. Do not be scared to ask questions and to clarify. We make mistakes in order to learn. There is nothing wrong to copy but you have to modify it. One nice thing I like about the professor is that he give chance (first warning) to students.  At least if you make mistakes unknowingly, you could change for better.

 

Acceptance of Life

My new roomie is an art student, a freshie.

While I’m looking through tutorial videos on how to install XAMPP on window and thinking what to write for my Response Paper, she is reading art tutorials book and practicing them. How nice.

For a moment, I was envious of how she could draw anytime she wants and having that as her homework; while my homework needs much brainwork and it’s so tiring.

But then, to think from another perspective, if I am an art student, I may be complaining about having to draw for every homework. And there is no limit of art form.

So either way, I should just appreciate for whatever I am able to do and do them wholeheartedly. 🙂

Self-actualization

Today I attended my first lesson on Human Resource Management. I always heard from my peers and seniors that it is a scary module for the engineers because it requires a lot of efforts to do reading, analysis, presentation, and finally study for a final examination.

However in my opinion, a loser loses because he admits failure from the start. If one could have a mindset of succeeding, i believe, nothing could be an obstacle to him. It comes with a lot of determinations and confidence.

It’s all about one’s mindset.  🙂

I came across this term of “self-actualization” just now and I think it is something that I should learn to achieve in life ( but most of all, I should still build my relationship with God 😉 ).

So here’s my understanding to “self-actualization”. It refers to how a person live his/her life to the fullest by maximizing his/her potentials and use them in a creative manner.

Here’s an excerpt from Wikipedia on the characteristics of a self-actualizer.

  • Efficient perceptions of reality. Self-actualizers are able to judge situations correctly and honestly. They are very sensitive to the fake and dishonest, and are free to see reality ‘as it is’. – learning to be less blur!
  • Comfortable acceptance of self, others, nature. Self-actualizers accept their own human nature with all its flaws. The shortcomings of others and the contradictions of the human condition are accepted with humor and tolerance. – learning to tolerate myself and others.
  • Spontaneity. Maslow’s subjects extended their creativity into everyday activities. Actualizers tend to be unusually alive, engaged, and spontaneous. – learning to be spontaneous and more energetic.
  • Task centering. Most of Maslow’s subjects had a mission to fulfill in life or some task or problem ‘beyond’ themselves (instead of outside of themselves) to pursue. Humanitarians such as Albert Schweitzer and Mother Teresa are considered to have possessed this quality. – learning to focus on my tasks and complete them.
  • Autonomy. Self-actualizers are free from reliance on external authorities or other people. They tend to be resourceful and independent. – learning to be more independent all the time!
  • Continued freshness of appreciation. The self-actualizer seems to constantly renew appreciation of life’s basic goods. A sunset or a flower will be experienced as intensely time after time as it was at first. There is an “innocence of vision”, like that of an artist or child. – learning to be appreciative to everything God has given me!
  • Fellowship with humanity. Maslow’s subjects felt a deep identification with others and the human situation in general. – learning to be more understanding.
  • Profound interpersonal relationships. The interpersonal relationships of self-actualizers are marked by deep loving bonds. – learning to love my neighbours and enemies (if there is any).
  • Comfort with solitude. Despite their satisfying relationships with others, self-actualizing persons value solitude and are comfortable being alone. – learning to treasure the feeling of “alone”. Actually I’m quite enjoying it…
  • Non-hostile sense of humor. This refers to the wonderful capacity to laugh at oneself. It also describes the kind of humor a man like Abraham Lincoln had. Lincoln probably never made a joke that hurt anybody. His wry comments were gentle proddings of human shortcomings. – learning to be more sensitive and tell only sensible jokes.
  • Peak experiences. All of Maslow’s subjects reported the frequent occurrence of peak experiences (temporary moments of self-actualization). These occasions were marked by feelings of ecstasy, harmony, and deep meaning. Self-actualizers reported feeling at one with the universe, stronger and calmer than ever before, filled with light, beautiful and good, and so forth. – heh, I often am overwhelm by these feelings!

In short, it is a whole new semester and last year of my University life. I have to change in order to go further and reach higher.

SD card Format Failed

I was all excited about my new Raspberry Pi , Gert board and Arduino Board. They have been there in the box for weeks and I finally took the first step to write the Raspbian Image into my new 16Gb SD card following the guide on the Official Raspberry Pi page.

1. I downloaded the SD Association Formatting Tool from here, installed and ran it.

2. I inserted my SanDisk 16Gb into my laptop built-in card reader.

3. Set “Format Size Adjustment” option to ON as shown below.

4. Clicked on Format and this was what I got: ” The Memory Card is write-protected. Please release the write protect switch.”

sd card formatter write protection error

So, as usual, i searched that on Google and some of the solutions that I have tried are:

1. Paste some tapes over it (as taught here or videos like this)

2. Use a software (USB write-protected) (like here)

3. Press the switch (as taught in most forums / support)

None of the above works.  So i contacted the SanDisk support. They do not seem to have encountered such problem before… and the technician mentioned : “SanDisk does not support the memory card to used as the boost device for the OS image.”

So I am stuck and still waiting for the support.

Other stuffs I tried:

– I couldn’t write any data into it.

– it works fine for my Canon camera.

– I can read the image files in it (image taken using the camera)

– i could not delete the file (there is no delete option and even if i press on DEL button on my keyboard)

I think I should get a Toshiba SD card instead.  : /

Pastel Typewriter

I think this is a great invention for the artist. I wonder if it is for real.

Anyway i went to my school’s Art Library today and it is like a paradise to me! There are a lot of illustration books and creative stuffs and inspirational graphics! I am definitely going to love it! Too bad that it is going to be my last year there 😦

I borrowed 2 books on fashion design illustration and a book on jewellery making! Hopefully I have time to browse through them if not read through.

Raspberry Pi I miss you!! 😦
