Designing Appropriate Computing Technologies for the Rural D
Posted by 0845 Telephone Numbers in Mobile Computing on August 29th, 2010
Designing Appropriate Computing Technologies for the Rural Developing World Tapan Parikh [Assistant Professor, School of Information, UC Berkeley] Abstract: People living in the rural developing world have many information needs that could, but are not, being met by information technology. Technologies for this context must be low-cost, accessible to diverse populations and appropriate for the local infrastructure, including conditions of intermittent power and connectivity. In this talk, drawing from the results of an extended design study conducted with microfinance group members in rural India (many of whom were semi-literate or illiterate), I outline a set of user interface design guidelines for accessibility to such users. The results are used to motivate the design of CAM, a mobile phone application toolkit including support for paper-based interaction; multimedia input and output; and disconnected operation. Through ekgaon technologies, a company that I co-founded, over 10000 microfinance group members in India are using CAM to maintain their monthly records. In Mexico, we are conducting a pilot where over 1000 small coffee farmers will use CAM to document their compliance with organic certification requirements. I will also discuss some of the more recent directions I have been pursuing with my students – including building mobile tools to improve the standard of health care delivery in sub-Saharan Africa, and designing information systems linking farmers to …

March 7, 2007 lecture by Phillip Zimmermann for the Stanford University Computer Systems Colloquium (EE 380). Phil talks about how the debate on the use of crypto has shifted since the 1990s, when it was a clash between civil liberties and law enforcement – in the 1990s, the crypto debate was about averting omniscience in governments, but today the encrypted VoIP debate may be about averting omniscience in criminals.

Vital Truths about Forensics Investigation
Posted by 0845 Telephone Numbers in Computer on March 14th, 2010
The world of justice seems to be shaped by forensics investigation procedures, and popular culture has integrated many character figures from TV crime series that depict great forensics skills. A forensics investigation can cover an impressive number of tasks: from autopsy techniques and forensic anthropology to DNA fingerprinting, computer facial reconstructions, toxicology and lots of others. Science constantly proves to be the best way to fight crime and support the legal system. Investigators are in charge of the procedures, and they are the once to bear the responsibility.
There are interviews, science experiments, methods and features that increase the variety of a forensics investigation models even further. On crime scene procedures are very complex and they in fact make the grounds on which the investigation is then developed or conducted. The crime scene provides the information for the lab forensics investigation, one would not be possible without the other, and negligence of any of them could lead to the failure of the justice process. The court evidence may be compromised if the crime scene is not analyzed correctly, therefore the best of experts use their skills to find evidence on site.
The peculiarity of a forensics investigation further depends on the type of crime that the authorities are dealing with. The steps of a data analysis for instance will be different than those of a robbery. Thus, special equipment is required for data retrieval as it is the case in computer forensics. The examination, the analysis and the reporting follow the identification of the forensic details. The procedures and measures vary for each of the steps involved although they eventually converge into one single viable point: the identification and the prosecution of the criminal.
Depending on what kind of forensics investigation is necessary, different experts will be involved. In fact, all the results of such criminal analysis are a sum of several people’s contribution, because several forensic departments go through the evidence or investigate different aspects of the criminal act. There are cases when the lack of evidence doesn’t allow the legal system to follow its normal course. There are hundreds maybe thousands of such cases in the archives of police departments all over the world.

Several Utilities of Computer Science Artificial Intelligence
Posted by 0845 Telephone Numbers in General on January 26th, 2010
Producing artificial intelligence has always been a fantasy for humans. From the age of Greeks, there have been attempts to automate what man do. Since the technology was not advanced at the time of Greeks, they used plain mechanisms to automate easy human like motions. Even before that, they had tales of gods who have mechanical servants.
The computer science artificial intelligence was emerged with the introduction of computer technology. Computer science artificial intelligence was a modern and scientific approach for the century old fantasy of artificial intelligence. Although there have been a number of several domains in the field of computer technology, scientists never changed the focus on computer science artificial intelligence. They knew that the computers have a potential to create artificial intelligence. Therefore, parallel to the developments of computer technology, the domain of AI was also moved on. When the functional and structured programming languages were developed for regular scientific and business programming, logic programming was brought in for computer science artificial intelligence.
Although the science fiction writers promised a rapid growth in the field of computer science artificial intelligence, the actual progression was not quick. From mid of 1940s, computer science artificial intelligence has come a long way, but far behind what has been estimated. As an example, people of 1950s judged that by year 2000, there will be mechanical human replication that can perform almost all the tasks the humans do. Although this was a blind estimate, there has been some kind of progress in automating the human cognition.
Currently, there are a number of computer science artificial intelligence areas, servicing for many fields of industries. Although the computer science artificial intelligence still is in research phase, the by-products have been usable in producing useful tools for fields such as aerospace technology, medicine, nuclear science, finance, and education. The software systems called ‘artificial intelligence agents’ carry out different tasks for helping humans with the procedure of decision making in these domains.
Modeling the human perceptual experience and knowledge still stay as the main target of computer science artificial intelligence. There are different approaches for achieving this based on various theories proposed. There are parallel research and development taking place in all these approaches with the promise that one will be able to compliment other at some point of the progress. In fact, this has been verified correct, as there are systems that use multiple artificial intelligence elements developed by various approaches for achieving a common objective. Although computer science is one of the modern ways of achieving artificial intelligence, there are can be many future ways for trying to model the human knowledge.

The Significance of Computer Artificial Intelligence
Posted by 0845 Telephone Numbers in General on January 9th, 2010
The Fields
Computer artificial intelligence is one of the most branched out fields of technology. It has its roots in almost all the technology fields in a well established manner. Space technology is one fine example. There are hundreds of computer artificial intelligence applications being used when launching a space shuttle. Since there is only a handful of crew in a space shuttle, not all the moniotrs and sensors can be supervised manually by humans. These computer artificial intelligence systems monitor these sub-systems and take decisions when a need arise.
Medicine is another area where computer artificial intelligence has contributed a lot. Medical test and the diagnosis is the primary action in medicine where the artificial intelligence is more worthy for. As an example, it can be a challenging task for a doctor to name and rule out something when the doctor has to look at thousands of minute readings of test reports. Therefore, computer artificial intelligence systems are used to read the reports and take the decision of diagnosing.
Financial industry has gone in to a new era with the introduction of computer artificial intelligence system for ecommerce applications. The professionals in the field of finance had to spend a lot of time examining the present stock market details for predicting the tomorrow’s market behaviors. With the introduction of artificial intelligence systems, this task has become as easy as clicking a couple of buttons of a computer software. The computer artificial intelligence software can study years of historical market information within a few minutes time and come up with an correct model to predict future stock price changes.
Domains of Computer Artificial Intelligence
Computer artificial intelligence was the result of the dream; people had to model the human cognisance. Therefore, human knowledge and behavior attached activities are thought as core compared to the other areas of computer artificial intelligence. Reasoning and problem solving is one of the main areas where the humans have been thinking of delegating to the future electronic minds. This domain directly involve in researches in step-by-step reasoning, solving puzzles, making logical decisions when playing board games such as chess, and dealing successfully with the unreliable or partial information.
Machine learning is one of the most interesting aspects of computer artificial intelligence. The intention is to have machine that self learn and create a self awareness of it. When exposed to a new environment, the machine should be learn the surroundings quickly and adapt consequently. This is also geared toward space technology as the computer artificial intelligence systems sent to other planets will not need prior training if they can learn by themselves within a short period of time.

Several Significant Views that Should be Involved on Computer Science Programming
Posted by 0845 Telephone Numbers in General on January 6th, 2010
Computer science programming is also known as ‘coding’ or ‘developing’. Usually computer science programming demands in writing, modifying, fixing, and maintaining the source code of a computer software program. Since the software source code is written in a computer science programming languages, the programmer or ‘coder’ requires to know the programming language in depth. The target of computer science programming is to have a piece of software that helps to execute some activity.
In any software development model the phase computer science programming is considered as the core step of constructing the software. Although there are ongoing arguments on whether the computer science programming is an art or engineering practice, I personally think that computer science programming is an engineering exercise. That is because there is a lot of logic and complex calculation being done in computer programming.
When it comes to the history of ‘programming’ it has had a different form. At initial stage, it was a mechanically defined operation (using mechanical tools) which was called ‘programming’. One of the most famous ‘programming’ incidents was Al-Jazari’s robotic musicians who were programmed using pegs and cams. Although this ‘programming’ was totally different from the type of the programming we see at present, there was a positive influence from the historical programming concepts to the modern ‘programming’ concepts.
There are a few essentials to fulfill in the modern computer science programming. Although quality requisites were not significant when computer science programming was first introduced, quality has become one of the primary factors in modern programming exercises. When it comes to quality, efficiency, performance, reliability, robustness, usability, and portability are seen as the critical elements. If the software program code is missing these parameters, then it is not a properly writen software.
For making the programmer’s life easy, there are many algorithms introduced and standardized. These algorithms can be reused for addressing many problems in the field of computer science programming. In addition to that, there are a number of methodologies introduced for making the computer science programming exercise easy. There are four computer programming langue classes based on the methodologies; procedural (or structured), functional, and logical. Depending on the methodology used, different programming language are best for development of software for certain domains.
When it comes to computer science programming languages, almost all the languages follow a simple set of guidelines; input, output, the calculations, conditional executions, and repetition. For writing a successful computer software, a programmer needs to understand and employ the above guidelines in such way that they comply with the architecture they are working on.

The Invention of Computer Programing and Its Gains
Posted by 0845 Telephone Numbers in General on December 26th, 2009
The phrase ‘computer programming’ has a universal scope. This action mainly means that developing or coding computer software using a computer programming language. Let’s try to understand how computer programming was evolved. At the inception of Von Neumann computers, there was nothing called computer programming. Of course there were instructions given to the computers for carrying out particular tasks, but they were loosely called programming. These directions lacked some of the properties of the programming exercises that we find nowadays.
In these early dates, the ‘programming’ was taken place as pure binary commands. The computers were fed binary instructions as the computers could not understand any other language. Since feeding binary instructions was the most challenging task, the scientists were concentrated on developing an easier method for giving instructions to the computers. As a result of this, Assembly language was introduced for the world of computer programming.
Since Assembly language made computer programming easy, there were more scientists for the purpose of writing computer programs for early mainframe computers. Still, computer programming was performed by a selected group of scientists as there were only a few computers available in the world.
Once personal computer came in to the market, the average computer usage and the computer literacy enhanced. Although there were only computer ‘users’ at first, ‘computer programmers’ began to emerge as there were more plain and straightforward computer programming languages were introduced. The invention of such computer programming languages made computer programming simple, interactive, and fun.
When the visual programming languages (the languages that had visual elements to drag-and-drop) started to come out, computer programming become further easy. Even children with a fair knowledge of computer use could write simple computer programs with these visual languages.
How to Get in to Computer Programming?
There are no formal qualifications or education requirements for getting in to computer programming. If you have degree in computer science, then it is surely a great foundation for your career. But if you have the imagination, creativity, and dedication required for writing complex programs, then you need not to have all the paper qualifications.
If you want to become an expert computer programmer, then you need to master the computer programming basics and techniques. Then, start learning your favorite computer programming language or the tool. Once you are an expert of the language, you can start working for a software company. But remember, to become a genius, you should know more than a programming language!
