The second revolution of technology

As the technology grows, people become more and more dependent on it. In the past, we might think that the technology will one day have consciousness and take on a wave of revenge. However, that everyone day may have arrived silently but with a scarier way. They are after our jobs.

From the basic muscle jobs to higher level cognitive level jobs such as doctors. For example an artificial intelligent name Watson. It can obliterate human in term of knowledge, seen on a game show. It is able to understand human nature language. And because technology can be made and remade, more and more can be produced. Meaning that in the future, you might have a version of Watson in the house yourself! Have it to do things, manage things for you. Sound good isn't it?

Not so fast, what about the jobs that we once depended on? They are slowing being taken over by exponentially growing computers. Then when we relies on it so much, it seems that we are their biological robot now. Like the airline trials Google Glass check-in. The man is not deciding anymore, the computer or the main server is. He is just there to “help” the operation. In the near future, we will have a humanoid robot replacing many jobs such as cashier, assistant, maids. Technology might one day replace our pets! Robot pets!

Our jobs are slowing being consumed by technology, and it doesn’t seems to have much new jobs now. What should we do about people that depend on muscle jobs? In the far future, many not be far, doctor may be replaced! We need to think about that and cope with it. Maybe learning how to code will allow us to have job controlling the robots again, instead of it control us.

Major Concepts

• Privacy concerns, job concerns, future concerns
• Our right as a human are being replaced
• Who is being control by it, digital divide.

Potential Advantages

• Many example such as google glass, the cow milker

Potential Disadvantages

• Did not state how to deal with the problem

Discussion Questions

• Who is controlling who?
• If our jobs are becoming less and less, what should we do about those jobless people?

The Heartbleed Bug

What is it?

In short it is a security bug in the OpenSSL cryptographic software library. Specifically, a simple logic error in the extension. This bug allow any attacker to obtain sensitive information from the server, given that they have time and some level of luck. These sensitive information include e-mail address, ID and password of clients, server’s master password, even decryption key of the server. The list goes on.

How did it happened?

It was a simple logic error in an extension, HeatBeat used to keep the connection between server and client alive without needing to reestablish the connection, written by a Ph.D. student in 2011. The extension was then reviewed by one of the four core developer of OpenSSL. The flaw however was overlooked and the extension was implemented to later official releases. By default, the extension is enabled thus the bug is present by default. 

Who got effected?

Any client that have servers that used OpenSSL version ranged from ONLY 1.0.1 to 1.0.1f. Why only between these number? Because before 1.0.1 the extension wasn’t present and after 1.0.1.f the bug was patched. This means that many giant website, companies that were using these version might have their sensitive information stolen without any warning at all. This means that YOUR id and password might have been stolen!

What was the damage?

The bug was already there for 2 years without anyone publicly disclose it which can indicate that many company have been attacked over the course of 2 years. Leading to many account being access by the attackers and messed with. Maybe the bank are hacked without them knowing. Even more alarming is that the attackers are NOT traceable. The attack this bug enable is silent and leaves no trace. Recovering from it will take sometime.

How to prevent it or recover from it?

Servers can be prevent heartbleed from happening any further by applying the latest OpenSSL security patch and users should change their password. However you must ensure that the server have already applied the patch or else the server can still be attacked.  There are many vulnerability test services out there that can check for such bug. Using them can find out whether your server is safe or not.

What did you learn from it?

I learnt that even a simple logic error in programming can lead to a global problem. And having an open source program can have more people to review the code and find the bug or flaw in it preventing any bug or flaw that can happen to be overlooked.

Samsung claims a graphene breakthough

Graphene is one of the recent super material found by scotch tape and pencil lead. It is way more stronger than steel, flexible and highly conductive. The conductivity was so good that researchers need to use E=MC^2 to understand the property of it.

Because of it's useful properties, researchers took interest as well as big corporations. Up until recent years, producing graphene was a big of a hassle and every unprofitable making them.

A research facility own by Samsung discover a way to produce graphene is a cheaper way using germanium, hydrogen and water to produce high quality, single layer graphene, this is very exciting discovery because many more technology can be mass produce and commercially available for many users based on the single layer graphene.

IBM have shown the potential of the graphene based processor, it was not perfect, but it have shown the effectiveness of it.

Picture

 

Strength of graphene

 

Single layer of graphene

Major Concepts

• Discovery of single layer graphene production at low cost
• Short idea of the materiel used
• The strength of graphene

Potential Advantages

• Link to many resources. Research paper etc

Potential disadvantages

•  Did not gave a brief idea of the process

Discussion Questions

• Given that graphene is commercially available, what are the imaginations?

Article Review 02

In the recent years, many dominate company have multiple interesting products. But even so other small company have their own products too, they many not be new innovational but instead they uses old concept and turn it into something new. They may look simple, but they are very unique.

First of all we have Cubelets, a cube-ish robot that can do just about anything (if you know how to assemble and program it) with different block to be used and program.

Have your family member felt scared of any medical instruments? If you are then Teddy the Guardian will fix that for you, but having those scary thing within a cute teddy! This Teddy have different basic features such as heart beat monitoring and other basic vital reads.

Have you or your family or your friend or anyone have a bad care for their teeth and you have to meet them everyday? Then this Kolibree smart toothbrush may be your solution, it can report to you such as if you have brush your teeth long enough or ensuring anyone who use it to remember brushing their teeth.

These are only few of the many interesting product that have been introduced at CES 2014. On the internet there are even more on the internet which is on kick start waiting to be backed by everyone! So be sure to check out other online product as well!

Major Concept

• The idea of product - Many product on the market are ideas that were made new.
• Possibility - Even there are big company around us, there will always be new product
• Uses - Even it is simple as a teddy bear, it can be for medical uses.

Advantages

• It is review of multiple product from CES 2014 which is very interesting

Disadvantages 

• If only the original article have more products

Question

• Even small company can make such unique products, why can't big company have such too?
• When a product is made, how long will each survive?
