Database and Database System (DBS)

Database stores data and the data is managed by the database specified model. The most common form of a database system is a relational database system. Database is one the most common wrongly used terminology by the layman. Basically, there is clear confusion between binary files stored on non interactive storage system and served on browser on GET request, like a HTML webpage is served from any FTP server. Only Apache like web server with proper setup is enough to serve so. No Database and Database System is required to process, store such ‘data’. In the same way, a simple PHP webpage will not require any Database and Database System, PHP is a server side programing language, in such case, along with Apache like web server software, PHP is required to be installed on the server to serve the webpage. In both cases, the actual page is physically present on the FTP server.

Twitter Header Design Tips : Inconsistencies in mention of Image Size

The developers guide in Twitter mentions the maximum size of Twitter Header to be of 1252×626 pixels. But in Twitter design profile it is 1200×600 pixels. Image size will not be a factor even for PNG output from PSD in Photoshop. Again Facebook failed. There is a loose less compression that does not affect the look at all. Compare with Facebook’s compression.
Twitter Header Design Tips : The Steps

The gray border is of Adobe Photoshop. I have used a Grid Pattern in black background to make it appealing ! The major important point is – the Twitter Header Design PSD file we have included is of 1252×626 pixels, but I discovered while uploading my own Twitter Header Design – it should be 1200 x (auto – nearly 624 pixels or like that) pixels. In other words, resize the width of final PNG output to 1200 pixel. Height will be auto in Photoshop. Here is is how I uploaded Twitter Header Design :

We need no scaling as our design is a final work. The option of Twitter Header is in design option in Twitter. After uploading it, it looks like this :

Add proper gradients to make yours one a bit dark, that white colored text output is automatic. It is important to use same photo everywhere, same name every where, if you have the desire to become a verified author and get an email from Google. As I use the lotus Icon in Twitter, it was important to use my ugly face in Twitter Header Design. Although, it is better to use your face in any case.

As many of our regular subscribers of asks this question – How and Where From to Buy a Digital Camera, this an article dedicated for really How and Where From to Buy a Digital Camera.
How and Where From to Buy a Digital Camera : The major wrongs most does
There are few things, which should never be bought from any online shop. This include the body and Lens (if applicable) of a Digital Camera. The major reason is, have sensitive components and can sustain injury which might not be apparent initially. Always try to buy a Digital Camera and its Lens from a reputed bigger shop. The hands on experience, checkup is very very important.
Second point is, everyone has a budget. The example of appearance of a  sales person, who typically arrives as a third person. These are kind of drama like setting to convince the most. Basically when you go to buy a remarkable thing in life, you loss some sense of judgment. They tries to get your approximate maximum budget which actually you might be hiding inside your mind, secondly they tries to judge your level of knowledge about the product.
How and Where From to Buy a Digital Camera : The To Do List
Fisrt point for  How and Where From to Buy a Digital Camera is, know about the Digital camera and Digital Photography first. If your need to buy a camera is an emergency, buy an entry level point and shoot camera. You can start from our section on Digital Photography, most important basic articles are already published, we always keep the articles to up to date. It will meaningless to tell you, do not buy an entry level DSLR, think trice, unless you yourself can judge the points.
Second point is already said, always buy a Digital Camera from a physical shop. It is not like buying a grocery item, it is quite sensitive and it is a big pain to get the money back or to get a replacement if you have received a compromised or defective product. You are not so busy that you can not visit 5-6 bigger shops within a month to get an idea.
Third point is, find a proper forum of your country on Digital Photography, people usually gives the feedback of a seller. Sometimes there are extra freebies given by a particular dealer.
Forth point is, never appear to the sales person as a noob. You truth or lie is, you do have a camera, you are buying this for parents or partner. Take a Tablet PC if possible to quickly check any question using our old good Google Search. This is important to know the batch data of a model. The shops will always push older stock.
Fifth point is typically for the consumers from India, India has quite high GDP and people buys stuffs on debit card or cash, not using credit card. There is a good chance to get more headache if the full is paid on spot. Try to buy with Easy Monthly Installment Scheme (EMI) – most sellers makes EMI like an bigger legal procedure as the EMI has the basic advantage despite paying the extra bucks as interest – If your product becomes faulty due to their problem, simply ask the help of a Lawyer (or ask in any Law Forum), how to complain as a consumer and how to legally stop paying the EMI. The material (camera) and money is also within your control.
Sixth point is bargaining. Not everyone is efficient at bargaining. This point of negotiation is also not possible to do in an online shop. Also in this sixth point, it is good to take a friend or relative with you who has good knowledge about Photography.
Seventh and Final point is quite important. Always ask the sales person to bring a new box pack. Do never allow them to open. Take the box package and check for any possible manipulation mark indicating prior opening. The shops usually opens from the bottom of the box package. Make it sure. Check the date of manufacturing, that should not be more than of 2 months. If you have doubt with the appearance, you can check on your Tablet PC. Keep the biggest point in mind – the shop owner and the sales person has more interest to sell than you have to buy.
This is all about How and Where From to Buy a Digital Camera.

Tips for Creating Inspiring Facebook Timeline

If you can not create any creative things yourself, probably it is better to hire a designer for a serious work. Here is short list of Tips for Creating Inspiring Facebook Timeline.
  • Getting an free opportunity to use a bigger banner like Facebook Timeline must be utilized.
  • As everyone says and saying since many years, the profile image, just like author profile must be either your candid portrait or the logo of your brand nicely post processed. It increases reliability.
  • The major problem of Facebook is, Ads on the right side and the old school blue colored navigation menu with Facebook white colored logo on left top. Both distracts the view. This is thoughtfully worked by Facebook to get more CTR. There is no padding within the bar and Facebook Timeline Profile.
  • If you use the same blue color (#3B5998) as your Timeline’s background, it will definitely draw the attention :
  • In case you are using #3B5998, there is no need to add the space, otherwise, add a transparent strip of about 10 pixel size or add the Facebook’s light background color.
  • For the first scenario, even just a white text will draw attraction.
  • For the second, that actually more will want, will give you a room to use colors and make it stand out.
  • The basic thing is all around the color composition of Facebook, because it is not white, it makes many colors unusable. To avoid this, you can use any color combination tool, use  #3B5998 as one color as simply its an undeniable graphical part of the webpage.
  • If you use your name or band name in a bigger font or as Strong Font Style, it will distract the visitor from looking the Facebook logo.
  • As usually, just like Photography, the points of attraction follows the age old golden rule of photography – “Centering every subject all the time is not very interesting. By using the Rule of Thirds, you can make your productions more appealing to watch. Divide your picture into thirds. Interesting elements of a picture should be placed on those lines or at their intersections.” (Greenwood, 2006)
  • Yes, the best thing is – your profile picture is actually in one of such point. Another points are -  Facebook Ads on the right side and the Facebook white colored logo on left top. Facebook deliberately has done it to follow  Rule of Thirds, so with adding a space on top and probably right hand side, makes the Facebook Timeline image a separate graphical element – visually.
  • I personally think, on the left side there should be the brand name or your name to override Facebook logo’s distraction.
  • Try to be minimalistic. Facebook users gets blind after viewing hundreds of Ads following all the rules to attract.
  • Composition is yours and should reflect your thoughts, use it as a brief introduction to the visitor.
  •  Refrain from changing your Profile photo too frequently, you can check, most successful bloggers are using quite older images.
  • There is an appropriate time of changing Facebook Timeline image if you want to attract in that way, its too individualized considering target audience, your work etc.
This ends the Tips for Creating Inspiring Facebook Timeline Profile Image. Some experts say, using a remarkable quote has special value as it reflects a personality. Pushing anything will fail if there is no real reason for attraction.

World Wide Web is different from contemporary hypertext systems. World Wide Web requires only unidirectional links rather than bidirectional, making it possible to put a link to a resource without requiring intervention from its owner. Moreover, unlike other protocols, such as HyperCard or Gopher, World Wide Web is built in an way, which made ​​the development of servers and clients without the restrictions of licenses.
Operation of World Wide Web
The World Wide Web is based on three core standards, HTTP as a protocol by which the browser information from the web server may ask for, HTML as a document description language that defines how the information is structured and how the documents are linked ( hyperlinks ), URLs as a unique identifier of a resource in the links is used.
Other standards of World Wide Web (W3) were added later, like Cascading Style Sheets (CSS) to create the appearance of the elements of a website.
The World Wide Web / W3C and other initiatives are to drive the development, therefore, in the direction of XHTML / XML, and CSS forward to regain the advantages of HTML. The ongoing efforts by the accessibility of Internet sites support this trend.

This technology was present in many laptops, mobile phones since 90s and early 2000s, especially in the devices from leading manufacturers such as Nokia and Ericsson, akthough they are still usually present but in usage has gradually replaced by technologies like wifi and bluetoth. VFIR has the theoretical speeds up to 16 Mbps.

Blog versus forum : Present versus history

Like Coke versus Pepsi, BMW versus Mercedes, another debate arising  now: Blog versus forum. We will discuss a brief history of both, present and possible future of both.
Blog : A shared on-line journal where people can post diary entries about their personal experiences and hobbies; “postings on a blog are usually in chronological order”. (Reference)
Forum : An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. (Reference)
Blog : The term “weblog” was coined by Jorn Barger on 17 December 1997. The short form, “blog,” was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog in April or May 1999. Shortly thereafter, Evan Williams at Pyra Labs used “blog” as both a noun and verb (“to blog,” meaning “to edit one’s weblog or to post to one’s weblog”) and devised the term “blogger” in connection with Pyra Labs’ Blogger product, leading to the popularization of the terms.
While the term “blog” was not coined until the late 1990s, the history of blogging starts with several digital precursors to it.
Forum: Forums perform a function similar to that of dial-up bulletin board systems and Usenet networks that were first created starting in the late 1970s. Early web-based forums date back as far as 1994, with the WIT project from W3 Consortium and starting from this time, many alternatives were created.
Justin Hall, recognized as one of the earliest pioneers in blog-like posting, first began publishing links from his Swarthmore College dorm room in 1994. He remembers the heady early days of online publishing, and notes that as entry barriers lessen, a new wave of microblogging is upon us. Thanks to blogs, zero technical know-how is required of today’s web publishers. All they need is an idea.
-By Jenna Wortham;
With both blogs and forums, users can post a comment and reply to other comments, thus developing discussions. In both cases, you can leave comments which may or may not be moderated and you may have to identify yourself with a name and email address.
In blogs post or the content is made by a single user, comments are minor part of it. It is more centralized, trusted individuals provide accounts of events and information.
In forums a discussion on a particular topic by allowing commenting of posts. Decentralized, needs other special group of users (Moderators, Administrators etc.) to control proper discipline.
(Adapted from Blogs vs Forums)
From Search engine optimization (SEO) point of view
Blog uses advanced technology which offers the writer to add various attributes, Trackback, RSS, Aggregation, Permalinking, Cross linking; whereas Forum uses typically relatively older technologies. Forum based on (basically) blogging platform, such as WordPress is used now, but not that popular.
From “getting information” point of view
To get a specific information; users generally searches the web by using a search engine and reaches either to a forum or a blog. However, to find  an information or to reach to a conclusion, user needs to waste much more time in a forum due to flooding of oneliner replies.
Blogs are more organized and informative. Infact, most of the popular website providing useful information to the users are blogs. Today, almost all know about Tutplus tutorials.
Social sites are killing forums
The necessity to communicate with like minded persons are now easily done via Facebook groups, Twitter or deviantArt (for artists, developers and users). Again, some of these social sites offers “blogs”, “notes”, “journals” etc.
When forum is more suitable for users
To solve a problem, users need a groups advice. Forums can serve the purpose easily. However, most of the bloggers are very active (though alone) and efficient, so this point blurs too.
Trend is rapidly shifting towards blog-reading and blog-writing. Almost all multi national companies (such as Google, Microsoft) involve employers to write blogs. More people are writing blog about the topic they know about. Definitely, it is creating a good source of information via internet, as a whole in a well organized manner.

What is a Cooperative Virtual Machine (CVP)

The concept of a Cooperative Virtual Machine  can be understood in this way – traditional virtualization solutions such as from VMware or Xen are unprivileged and therefore are under the complete control of the host system but in Cooperative Virtual Machine the core processes of both the operating systems independently run.
Advantage of this approach is to achieve a good performance with relatively less development time. The disadvantage is that, instabilities and vulnerabilities of the guest system to the host system. In case of crashes on traditional virtualization solution, from the host system it can be stopped and restarted. A Cooperative Virtual Machine can also crash the host system. Because of its deep integration in the host system Cooperative Virtual Machine run with administrator privileges and has also the probability of malicious softwares in the guest to get full access to the host system. - read more

Desktop Virtualization with VMware View : Overview

Desktop virtualization generally describes the complete virtualization and relocation of the operating system in a data center. Thus the previously coherent system of hardware and software is divided and is shown separately. Only the image is displayed on the screen of thin clients or computer inputs from peripheral devices are forwarded to the data center for processing. This is achieved by different protocols of the various manufacturers.
The operating system, in this case, is represented by the virtualization software as it would run independently on a single physical machine. The virtualization software is the various hardware components, so that the operating system may appear to operate normally interact with the hardware. Thereby it is possible to execute the same number of virtual machines on a single physical machine.
Desktop virtualization for developed infrastructure systems are used to take the deployment and management of virtual desktops. They work with a variety of software and hardware components to deploy desktop virtualization.
Desktop virtualization is experiencing strong economic growth and is becoming more widespread in business. Analysts predict that the market for desktop virtualization in the business sector in the coming years is experiencing significant growth and more and more companies will use desktop virtualization.
Major competitors to VMware in desktop virtualization are Citrix and Microsoft. Other suppliers in the market with significantly lower market shares are still Oracle / Sun and Parallels.
