Evaluating web resources and identifying the audience As an investigative reporter I used the following websites to check the claims of the politician made in his proposed bill. The New York Times: When evaluating I found that one of the sources used were form the New York Times. This website has had presence on the web since 1996, it is also ranked one of the top websites and is ranked 59th by number of unique visitors. The target audience is not limited to United States and people from all around the world use this website. As The New York Times is one of the leading newspaper the information on its website is updated regularly. The articles published in this website are of high quality and professionally reviewed. As the articles are written by professionals and are reviewed the articles are relevant and thorough.[ nytimes (2015)] CNN: Another website that was used is CNN. Like the New York Times it is also one of the top websites with audience from all around the world. The information is updated on a regular basis as it is very important for a news website to keep updated. The articles published on the websites are written by experienced professionals and are reviewed properly by other people before getting published. The information in the articles is not very thorough but is accurate and relevant to the subject. [CNN (2015)]. Mother Jones: The third website used was Mother Jones. It is a website which provides investigative reporting on politics, culture, human rights and culture. As the website publishes news and blogs about politics, culture and environment, the audience of this website is not limited to United states and is spread throughout the world. Like the two websites mentioned above the information on Mother Jones is also updated...

Data Information Decision.

Ramsy Ramsy

Data Information Decision Managing Database Database management plays important role in a company’s growth and success. With the advancement in technology and research methods, data security has become very sublime and sensitive issue in present times. Structural design and managing techniques of data go hand in hand for making data secure from outsource stations. Primary decisions to manage data by database administrator A database administrator has to perform tasks such as to improve structural design, data integrity and performance of the database. The database administrator has to be very familiar with the latest technologies being launched globally and locally to understand if current data design has any defects to improve. Technology keeps improving and so does a database design and software. If a technological change affects the database system of the specific company, it is the decision to be taken by database administrator to handle that and make changes in software or hardware being used to make database. Database administrator is responsible for securing data from any outsource unrelated source to the data. Building firewalls and updated technique must be introduced by the database administrator. Humans errors or system faults can make the data unsecure and data can reach in the wrong hands. Hackers and thieves can be harmful for the system so proper steps should be taken to avoid any harmful incident. Data Integrity Data must be decentralized in a way that only related people have access to it. Data Administrator must distribute data usage rights in such a way that specific fields are provided access to specific people in the company so that in any case of mismanagement or data leakage, specific people could be held responsible and accountable for it. Data integrity must be maintained to keep data consistent. Data consistency could be improved by better structure...

Css & Web Environment.

CSS & Web Environment Pros and Cons of Color Specification techniques in CSS Cascading style sheets provide a wide range of color combinations to be added into webpages. With the advancement in web development languages, color designs have also been improved in contrast and mix. Although CSS caters different methods but it is the programmer’s choice to adapt to any of the available techniques for color specifications [Alexander Dawson (2011)]. Hexadecimal value notation is the classical technique bearing highest support of the browser. It uses three or six digits in hexadecimal to convert it into colors and these hexadecimal codes are of highest priority to preciseness. RGB value Notation uses the characters from 0-255 for three color combinations which are red green and blue to create a balanced mix of the three numerals. This method provides the great control and diversification of colors. HSL notation is a sub domain of RGB color notation because the only difference is that we specify color combinations in percentages. HSL method customizes hue, saturation and brightness of colors in threefold notation. This method is, like RGB, gives wide range of colors to pick from and it is easily readable format. Color Keywords Notation is used as a beginner’s programming practice where the name of colors is used to specify color combinations. It has its limitations when it comes to range but it is easily memorized and practiced [Alexander Dawson (2011)]. Apart from these notation methods, CSS code can be inline, internal or external. Inline method has fast loading but no reusability. It has the highest precedence among these three but considered a bad programming practice. Internal Method is also fast loading but cannot be used to numerous pages. External coding style is reusable and provides readable and cleaner code but it has greater bandwidth...

Css Styles.

Ramsy Ramsy

CSS Styles Introduction Webpages can be designed using Inline, Internal and External methods of writing CSS code within HTML tags and each HTML element can be styled separately. It is up to the choice of programmer to use any one of these but the decision must be taken after taking the web design under consideration. Inline style is the CSS code embedded inside the HTML tag, Internal CSS is when the programmer declares a “<Style>” tag in “<Head>” area of the code and External method is separating the CSS code from HTML and writing it into a distinct Cascading style sheet with file extension of “.css” [Clay (2014)]. CSS Style Precedence Sometimes all three forms of CSS code are implemented within one code which at times may create confusion that which style will take higher priority which is why a comprehensive understanding of precedence levels is necessary. Inline Style has the highest precedence, Internal Style comes second and External style has the lowest precedence amongst these three [Clay (2014)]. For example, if you are designing an HTML website with several pages, you code in the external style sheets but as the project develops due to its dynamic nature, overriding becomes compulsory element of any dynamic website. To accomplish overriding of external styles, inline and internal styles come handy because they have the highest priorities. Similarly, in the same project, editing the smallest element on any webpage is easily managed through inline styling. So, in dynamically managed websites, all these three styles are embedded as per requirements [Kelly Lucas (2009)]. CSS Special Features CSS provides a wide range of features to design a website more attractive and catchy. CSS transitions, Light weight Sliders and multiple color addition to an already made project using external CSS files are some of the key...

Compressionarchive Utilities.

Ramsy Ramsy

Compression/Archive Utilities Comparison & Contrast Utility Name Operational Description Most Common Arguments & Effects Algorithms Implemented 7-Zip an open source, with an open architecture, for manipulating archives. Has a high compression ratio with the ability to reduce files to 40% more than its alternatives. Extra features include password protection as well as adjustable compression levels, compatibility with multiple archive formats. It also provides command line and Graphical user interface. Furthermore it allows integration with window shells, provides the option of self-extraction of archives, and archive headers compression. Command-Line (non-switch) To reduce command line’s length, switch options can be utilized. For switch options that take optional string arguments, these arguments must be entered as a token string as the last option in a, to follow 7-zips format. Deflate: Standard LZ77 and Huffman based algorithm. LZ77 works by locating repetitions while Huffman is a form of prefix coding (Feldspar, 1997). The version used is written in C++ and has a hgh compression rate. BZip2: Standard BWT(Burrow-Wheeler Transform) algorithm. Only compresses sngle files. But is more effective than Deflate in most cases. LZMA: Optimized LZ77 algorithm. Its more space-efficient than BZIP2. It performs lossless data compression. PPMD: Effective for compressing files containing natural language. Variant of PPM (Prediction by Partial Matching). Loseless compression algorithm.   gzip A replacement for compress. Basically it finds matching strings throughout the file and replaces them to reduce the file size. Command-Line Argument provided: Compresses file, with .gz format and the original is deleted. Argument not provided: Standard input/output. LZW (Lempel-Ziv-Welch): Universal lossless data compression algorithm. Simple to implement. Deflate: Combination of LZ77 and Huffman. Standard reference implementation. rar Uses similar tools to that used in ZIP file. Basically used to compress the media content that has to be shared over the internet. Files can be divided into...
