Attack on computer memory reveals vulnerability of widely used security systems


 

Attack on computer memory reveals vulnerability of widely used security systems .

An interesting news about breaking into laptops, which are "secured" by encrypting disks. TrueCrypt is also vulnerable (due to generic design of the encryption suite).

"Disk encryption technologies rely on the use of secret keys -- essentially large random numbers -- to encode and protect information. Computers need these keys to access files stored on their own hard disks or other storage systems. Once an authorized user has typed in a password, computers typically store the keys in the temporary RAM so that protected information can be accessed regularly. The keys are meant to disappear as soon as the RAM chips lose power."

Why metaphor works?


The question, which arose was - why metaphor works? Should it not be formed according to our life experiences, religious beliefs, country we live and surrounding environment? The answer is somewhat moody - if you do not have experience and archetypes when creating metaphor - your expression could be not so effective, but in general the topic is about universal things. Metaphor in deeper sense is not some kind of language figure, but it is cognitive process, which starts before we say (get) our words, which is fundamental in every human being. Lakoff and Johnson says, that metaphor is closely related to human perception of space and time and motoric reactions, which are defined by body and brain functions. This implies that (as every human has a body and a brain) conceptual structures and alike in all mankind. When using metaphor one can describe unknown ideas using very simple descriptions, which are very known to a person, due to the fact, that she is familiar with them from within. So metaphor is a description of physical and perceivable state of a person, which could be communicated using words only (visual, verbal means of communication), which create resonance within unconscious mind.

On Metaphor and Advertisement


..So the start of journey to rhetoric is to understand how unconsciousness works, to go deep to psycholinguistics. As it has been mentioned before - this is related to unique skill of a human - to notice and summarize similarities between different individuals and object classes. It is the same principle which is used in metaphoric processes. The foundation of metaphoric transformation is external description of inner qualities, purpose, functions, sometimes to create emotional impression and assessment.


The guys in Cognitive Linguistics have tried to prove that there is such thing as fundamental conceptual metaphor theory as one of the primary tool for cognition and perception. Conscious or unconscious use of conceptual metaphors in advertisement help to create the atmosphere of subtle details, which could not be shown otherwise. In pursuing the goal to create more effective advertisement one can use metaphors for very specific and exact purpose: I.e. by creating playful tension between metaphoric and natural meaning you can communicate multidimensional perspectives of cognition.
By changing the natural (usual) way of seeing and understanding the world by using metaphors one can open new semantic horizon, which allows to make new, unusual meaning in usual environment.
This expands definition of advertisement: advertisement is multidimensional, cultural business, which is not only creating its own goods, but also seeds social values, specific point of view and ways of consumer behavior (Rubavičius, 2004, p.17).

So research which trends of metaphoric transformation in advertisement, how the prospect of life of language systems is reflected in advertisement is very important not only for the theory of advertisement, but also for practical reasons: it can show which context is more effective and persuasive when influencing the consciousness of a consumer, and creates a framework for  creation of more effective psychological and commercial advertisement.

Semantic Fields and Tag Clouds


Tag Clouds can create perfect semantic fields and it is possible to understand more about the author (in case of blogs), the main idea of website and the spirit of the community (in case of portals or social networking sites).

Also semantic fields can be used to explain for the customer why in the hell he needs Tag Cloud in the first place.

Provided that blog is written by the same person and the person has more or less stable area of interests and is using tags in proper way: it should be possible to create one mental image, which would define the blog. On the other hand, if person tags posts according to things he wants to show (or tries to manipulate you) - still you will get some kind of understanding what drives her.

While it is easy to influence creation of tag clouds for one person blog, it is much more difficult to manipulate it if the blog is written by different (independent) persons and almost impossible to do it if tag clouds are created on the fly in social networking sites (of course - if data is not tampered with).

Also this reminded me a friend, who is doing text analyzes for SEO, basically what he does is extracting semantic field from the text an analyzes if it contains keywords which he requires. If not - the text is rewritten in such way, that semantic field matches keywords.

I have started to think about the tool, which creates Tag Clouds by counting repetitions of words and creating a cloud for an article or for a blog. Now just there is a need to find a perfect formula..

Semantic Field


 

Me: hi, teach me rhetoric ;)
Mentor: this is very interesting topic.. vast, sophisticated and broad structure. yes.. it is very interesting..
Me: yeah, I am already hooked on in. Where should I start?
Mentor: what are you interested in? I am sure you are not interested in classical (western) rhetoric... but I think it is a foundation.
Me: Of course, I am interested how to apply it in practice ;) Writing articles for example.
Mentor: Oh.. So you are not interested in rhetoric as a science.. but as a persuasive communication ;)
Me: Naturally I am more interested in how to use it.
Mentor: you can buy that stuff in any bookstore: how to persuade, how to influence, how to win, how to earn....
Me: All this is available on the Internet too ;)
---
Mentor: learn about semantic field, kid.
Me:  The semantic field is the mathematical support for introspective information for human being.  With Kripke models, inferential rules are possible among the worlds. Because at any sentence in logic we can associate a part of the semantic field, any conclusion of a chain of inferential deductions can be shown by semantic field. One use the tool of the field theory and the other the tool of inferential process to describe uncertainty in information and also to discover logic structure inside the data.
Me: so this could be used in computer science.
Mentor: maybe. Try to find out why it is useful for linguistic purposes.
Me: will try.. a) if you want to create a metaphor or to analyze existing one, b) it can define more exactly uncertain things and ideas, c) it creates mental images, which are useful to transmit information between two persons speaking different language.
Mentor: I will try to explain:

    There is a good science, called Cognitive Linguistics. To make long story short - two guys, Lakoff and Jhonson, wrote a very popular book - metaphors we live by. In that book you can find very clear defined concepts. Probably you can download it on Emule. Also you can read about semiotics, which is the same, but in the opposite direction.
Me: I will buy it.
Mentor: there is no need to buy it.

Hungry Feeder


My good friend sent an article about Innovation Feeder, which I really like, especially that he has added the comment - "look, here is something about you".

You can read the article here - Take me to your feeder

If you don't want to read it, just short definition:

"The definition of a “Feeder” is one who stimulates people’s minds with a constant supply of new trends & ideas. At least that’s how the big cheeses at Business Week define it. So how can you get around this in your own company?"

I visualize feeder as a black whole, which sucks information and data in any way possible, everything is interesting to her, because she can see or create connections with everything, going back and forward in time, also can "see" butterfly effect in progress, which is very interesting quality in itself. And as the black whole - after transformation and creation of new connections feeder spits out it back. She is not a walking encyclopedia, but concentrated shot of ideas, creative energy and motivation to try new things out.

binary_blackhole_021003_02

These things do not come for free:

Feeders are usually very bad to put ideas in action, because as you have lots of them - there is no point to even try to do it. After all - why bother to do anything, if tomorrow you will have five new ideas about the same subject, which will be even better to implement? This requires some kind of discipline - very difficult for a Feeder. Or - Believers, who would be activated by her and try to achieve something real.

Sometimes, if not all the times Feeder explanations of things or ideas are so bizarre that you cannot get the point (which usually exists, but you need to have lots of background information to really grasp it). That means that good Feeder needs to learn how to present his ideas clearly, which is difficult task in itself and gets her to spend huge amount of time to gather any method possible to understand how to do it perfectly and in the process creates even more ideas (that usually are not related to the subject at all, at least not to any external observer).

It is difficult to focus for a Feeder on one task for longer time than five seconds (to write this post it took me about two hours), so they have to use some means to make things happen. For example - work on seven things simultaneously and dedicated short time period at a time in a round robin fashion. At first it is very difficult to get back to the task you have started and makes Feeder unhappy, but with time it becomes a habit, which can be useful.

Probably there are more issues, will try to come back to them later - have other six matters to attend now...

Rhetoric and Art of War


Yesterday I have received an article and a book about rhetoric, specifically about inventio. It has ruined everything I thought I knew about it and made be interested in the stuff. For example I have thought about rhetoric as an art to put your ideas in a nice way, but after 1/3 of the book I have another perception - rhetoric is a weapon to influence people decisions (or even the way they think about ideologies).

Classical (western) rhetoric consists of several parts: inovatio, dispositio, elocutio, memoria, actio.

Inovatio is concerned about system or methodology of discovery of proper arguments (like basic framework), which resembles Laying Plans, Waging War and THE USE OF SPIES in SunTzu Art of War.

Dispositio talks about  organization of arguments or strategy. In SunTzu you can find about it in ATTACK BY STRATAGEM, TACTICAL DISPOSITIONS, WEAK POINTS AND STRONG.

Elocution's primary idea is to lay out concepts and ideas into sentences or - MANEUVERING, THE ARMY ON THE MARCH.

Memoria and Actio related to oral exercises, like speech, gestures and so on, so it is irrelevant in writing.

If you carefully study ideas in both Classical rhetoric and SunTzu Art of War - you will get a feeling that they are laid out according to some universal principles, which could be interpreted to come to life because of physical, biological and chemical structure of human brain.

The only big difference between rhetoric and art of war is this:

While "receiver" of rhetoric attack must understand at least half of what is being said to be intimidated or manipulated, when going to war you can just drop few bombs and arguments will be very clear. Which is the reason probably why you want to kill stupid people, when you see that your arguments are not working on them ;)

"South Korean firm is offering to clone pet dogs" - it instantly reminded me the not-so-good-but-fun-to-watch movie with Arnold. Here we go - RNL Bio - the world's first commercial dog cloning service.

So what can I say - the day is coming! How much further can we go?

McDrive? No! One step further - bank drive



Bank drive
Originally uploaded by Illuminatus!
Before going to the gasoline station it is adviced to visit bank drive and withdraw money.

As in gasoline stations there are boys, who will pour fuel into tank - you do not want to trust your credit card to them.

The funny part is that minimum amount you can get from the ATM is 500 SAR and the smallest bill be will 100 SAR.

For 100SAR you can fill about five cars (approx 20 euroes).

TED | Talks | Vilayanur Ramachandran: A journey to the center of your mind (video)


Very interesting and fun video - one of the best of TED Talks!

"In a wide-ranging talk, Vilayanur Ramachandran explores how brain damage can reveal the connection between the internal structures of the brain and the corresponding functions of the mind. He talks about phantom limb pain, synesthesia (when people hear color or smell sounds), and the Capgras delusion, when brain-damaged people believe their closest friends and family have been replaced with imposters."

Few facts about it:

Kingdom Centre (Arabic: برج المملكة‎) in Riyadh is the tallest skyscraper in Saudi Arabia. With a height of 302 m (992 ft), it is the 37th tallest building in the world. The tower is built on area of 94,230 square meters of land, while the whole centre is built on a total area of 300,000 square meters. The tower is host to the highest mosque in the world.

Hell


Today it finally got me. Boredom. Saudi Arabia is very good place if you want to earn some cash, but very bad if you want to spend it and are not interested in cars.

It is like prototype version of hell: you live for ages,  have everything you need, but nothing to do. Well you can eat of course, but now I have thoughts such as - "Man, eating today? Not again..".

Imagine the situation, where you cannot go insane, you do not die and are sitting in the dessert. Like you are alive, but have nothing to do. Just you and your thoughts. After few thousand years you finally understand that you cannot escape from it. And it is boring as hell.

So life here reminds me that image of hell - you are in survival mode, not because it is difficult to survive, but just you do not need any other function. No headaches, no long nights, no drug abuse - nothing.

This has been an advertisement for meditation.
