A long answer to a short question…

How Fast?

Moore’s “Law”

 

A casual prediction by Intel

co-founder Gordon Moore in 1975:

 

Turns out the prediction has been

roughly correct, even up till today.

 

Used to (incorrectly) describe

similar exponential growth trends in

many other technical aspects

“The number of transistor inexpensively available on an integrated circuit chip is going to double every two year.”

Network Access Speed Evolution

2nd semester, 2012 CCST9015 - Dr. H. So 8 Year 2000 1990 1980 1970 Speed (bps) 100 1000 10k 100k 1M 10M >20000x

What is the big deal?

 

What does 20,000x speed improvement means?

 

Consider “downloading” 1 DVD from the Internet:

 

Standard engineering question:

2nd semester, 2012 CCST9015 - Dr. H. So 9 Modem Speed (bps) Download Time 6M 11 minutes 14.4k 3.2 days 2400 19 days 300 5 months

What speed of modem do you need if you want to download the DVD in 1 minute?

CCST9015 Questions

 Will you download a DVD from the Internet

if you had a 60 Mbps connection? Why/ Why not?

 Will you upload a DVD to the Internet if you

had a 60 Mbps connection? Why/Why not?

 Company A claims that it can provide you

with a 60 Mbps bandwidth for DVD delivery

for HK$300 per month …

•  Is it technically possible? •  Will you buy into it?

 If you do have a 60 Mbps connection to the

Internet, how can you use it to improve the lives of the people living below the poverty

line?

What’s so special about this video?

First ever video uploaded to YouTube (circa 2005):

http://www.youtube.com/watch?v=jNQXAC9IVRw

What makes YouTube successful?

 

Enabling Technologies

• Substantial growth in network speed

• Fast upload, smooth streaming

• Substantial growth in storage capacity

• To store all the uploaded video

• Much better mobile access to the Internet

• Watch/upload from mobile phones

 

Possible non-technical arguments

• People are more willing to “share”

• Business incentive

(3)

What has YouTube’s success

brought to us?

 

Perfect platform for pirated content?

 

Business model?

 

Destroy the entire movie/music/TV

industry?

 

Destroy journalism?

 

Destroy privacy of people?

 

Political tools?

What CCST9015 is about…

 Understand how modern electronic technologies

have shaped our daily life •  The pros and the cons

 Identify important electronic technologies that will

likely to have high impact to our future

•  Where are we heading with current technology trend •  But we can never predict the future

 Develop critical intellectual enquiries concerning

technological innovation through basic scientific knowledge

•  Don’t be fooled. Be knowledgeable.

Critical Thinking

 

A cognitive pattern that will reappear over

and over in CCST9015:

2nd semester, 2012 CCST9015 - Dr. H. So 15 Fact Arguments Conclusion Analyze

Example

 

What do you think about this statement?

With the ever increasing speed of

the Internet, the traditional mail

service is going to get completely

replaced eventually.

Arguments For

 

Sending a mail takes 1 day, an email takes

< 1 second – it’s email age now

 

Postcards can be replaced by posting

pictures on Facebook

 

Fact: postal services in many countries are

already on the edge of bankruptcy

New York Times Sep 4, 2011

Arguments Against

 

You’ll always need the postal service to

send physical parcels

 

Receiving an actual letter provides

unparalleled sentimental values

 

There are many people who don’t have

access to the Internet

• Really?

 

Fact: mailing is faster than the Internet

• Really?

(4)

Getting the facts right

 

How many people are using traditional

postal services

• Why/Why not?

 

What is the revenue for traditional

postal services?

 

How about couriers such as FedEx,

UPS, DHL?

 

Can traditional mail be faster?

Physical Mail vs Network

 When the data transfer is large, traditional postal mail has much higher bandwidth than any Internet connection

 E.g. Amazon AWS Import/Export allows company to send data to the Internet “cloud” by physically sending hard drives.

 When is physical mail faster?

2nd semester, 2012 CCST9015 - Dr. H. So 20 Available Internet Connection Theoretical Min. Number of Days to Transfer 1TB at 80% Network Utilization When to Consider AWS Import/Export? T1 (1.544Mbps) 82 days 100GB or more 10 Mbps 13 days 600GB or more T3 (44.736Mbps) 3 days 2TB or more 100 Mbps 1-2 days 5TB or more 1000 Mbps < 1day 60TB or more

Analyze

 Ask yourself:

•  Is there enough evidence to support either side of the argument?

•  Is the technology behind the claim actually make sense?

•  Is the argument even logical?

 Look from many different angles:

•  It is not always about the technology •  What is the effect on the society as a whole? •  business incentives?

•  Political incentives?

•  Is this problem local to HK? Or is it a global problem?

 Many more…

Make Conclusions

 

Which arguments do you agree/disagree?

• Why/Why not?

• On what group

 

Make suggestion/recommendation/

prediction

• Suggest new idea

• Suggest new direction to look at a problem

 

Action

• Put what you believe into action

In short …

Learn to be a better global citizen in this technology-driven world.

Attention Span

 

the period of time during which you

continue to be interested in something:

 

Two 45 mins lectures + 15 mins break

• Remind me if I forget!!! Percentage of people paying attention Time (mins) 20 40 60 80 100 120 0 0 50 100 25 75 2nd semester, 2012 CCST9015 - Dr. H. So 24

Plagiarism

  Absolutely ZERO tolerance in plagiarism

  My unofficial definition: “Any copying and/or stealing of materials and/or ideas from any person other than yourself” is regarded as plagiarism.

•  i.e. includes copying work from previous semester, from the Internet, from your classmates, etc.

  In the case of an individual assignment, you will automatically get a ZERO mark for the assignment if acts of plagiarism is detected, including, but not limited to homework and quizzes.

  In the case of a group work, any act of plagiarism from any member of the group will result in ZERO mark for the entire group, unless such act has been reported by members of the group not involved in such act, in which case only the person(s) involved will receive ZERO mark.

  In addition, any person involved in act of plagiarism may be subject to further investigation by the relevant University disciplinary units.

Readings

  Some of them will be assigned reading during the semester:
