Apple Bonjour


Apple Bonjour is a group of networking technologies designed to help devices and applications discover each other on the same network.
Bonjour is Apple's version of the Zero Configuration Networking (Zeroconf) standard, a set of protocols that allows certain communication between network-connected devices, applications and services. Bonjour is often used in home networks to allow Windows and Apple devices to share printers. Technically, Zeroconf is a group of open Layer 2 protocols for quickly setting up an IP network. The original name of Bonjour was Rendezvous, but Apple changed the name in 2005 after a trademark dispute with a company called Tibco Software.
Bonjour was originally designed to locate Apple devices on a single network with one router, but because it is such a useful tool for network administrators dealing with IT consumerization, wireless vendors are helping to bring Bonjour to the enterprise. Aerohive, for example, has released a free VMware virtual appliance that allows Bonjour to operate across networks on different subnets or virtual LANs. Cisco has announced that it would turn its WLAN controllers into a Bonjour gateway, providing network administrators withpolicy-based management capabilities BYOD end users.
Bonjour software comes preinstalled on OS X, the Mac operating system, and on iOS, which runs on iPhones and iPads. Some Apple software, such as iTunes and Safari, automatically installs Bonjour on Windows machines.

LIKEJACKING

Likejacking is a variation on clickjacking in which malicious coding is associated with aFacebook Like button. The most common purposes of likejacking include identity theftand the dissemination of viruses, social spam and hoaxes.
A "Like" is an endorsement of a post, product, business or some other page content, registered by clicking the button associated with that item. There are two basic types of likejacking. Both involve a post that is likely to attract the user, such as an offer for a free gift card or a compelling video, and both spread through ill-advised or automatically generated shares and likes. The initial post may be enabled through a hacked account or the acceptance of a request to add a friend, who turns out to be a scammer.
In one variation, clicking on the post itself brings up a splash page that is coded so that if the user clicks anywhere on the page, it registers as a "Like" and shares the original post to the user's Facebook wall. The purpose of this type of exploit may be spreading a hoax or fraudulent promotion of a business or product.
In the other version, the developers responsible for the post add coding to the Like button that leads users through a series of pages designed to gather their personal information, such as surveys and membership applications. The scammer may receive payment for each completed survey. Applications for membership may require credit card information for "fee payment."
Here are a few common examples of likejacking:
  • An image of a sick or injured child with text claiming that Facebook will donate $1 toward the child's care for every like.
  • A false offer for a free voucher or gift card. These have included offers of $50, $100 and $250 give-aways from Starbuck's, Costco and Walmart.
  • A bogus offer for a free iPad, iPhone or other popular electronic device.
  • An image of an attractive young woman along with a compelling message such as "The Prom Dress That Got This Girl Suspended From School."
To protect yourself from likejacking, security experts recommend that you use caution in clicking, liking or sharing posts and be extremely skeptical about any free offers

Tumblr

Tumblr is a free social networkingwebsite that allows registered users to post multimedia content to their own customizable blogs.
Given its simple, concise nature, Tumblr is not best suited for long text-based posts like full articles; rather, it's good for broadcasting short messages to readers. Themicroblogging platform is praised for its simplicity in aesthetics, management and content posting. Many Tumblr blogs feature humor, fashion, design and art.
Each Tumblr blog is referred to as a tumblelog. Members can post text, images, videos, links and audio files to their tumblelogs. They can personalize their tumblelogs with different themes, which are largely free but can be professionally designed for a price. Primary tumblelogs are public and cannot be password protected, but specific posts can be made private. One account can host multiple tumblelogs.
The blogging site features a dashboard interface for accessing most of the website's features. Members can follow one another, "like" content with the click of a button and comment on posts.
A popular tool is the "re-blog" button. Users can click on a post they like and it will be published to their own Tumblr for followers to see. Tumblr limits users to 250 daily posts to control bandwidth use and spamming. There are Internet petitions asking Tumblr to terminate the posting limit because, some users say, their freedom of speech is being oppressed.
More than 50% of Tumblr visitors are under the age of 35. The retention rate of users istwice that of Twitter. Tumblr was founded by David Karp in February 2007. According to Tumblr, as of July 2012, the platform boasts more than 70 million blogs, 30 billion posts and 16 billion monthly page views.

Salary Negotiation Tips to Bargain For Salary Increase


Do you have the feeling that your employer is continually taking advantage of you? It maybe the right time to plan for a salary negotiation if you feel that you’re constantly contributing good value to your company and not getting the pay that you deserve. Effective negotiation helps to resolve situation like this and find solutions that are acceptable to both parties.
Most people are very uncomfortable discussing on the topic of salary increase. This kind of feeling is very common as we are all having fear of being rejected or worry to upset someone during the negotiation. To demand for the right salary that you deserve, you’ll need to learn some negotiation fundamentals.
Asking for a salary increase has to begin with a strategic plan, and preparation is the key to be successful in any form of negotiation. You can get a pay increase even if your company is under salary freeze. Here are some effective salary negotiation tips and tactics you can use to fight your case without fear.
1) Assess the situation and know what to target for Before asking for a salary increase, you need to explore your company’s policy on salary. Check out if there is any established range for your position. Find out if there are other people in your organization doing similar work, and how much they are being paid. If there is no constraint from the pay policy and you’re indispensable, you should feel optimistic and confident with the salary negotiation.
You can bench mark “job search” web sites on the internet to determine how much other companies in the same industry are willing to pay for a comparable position. Different organization may use different job title for the same work. Therefore making comparison of the job scope maybe needed. Understanding the current market value for your position will determine how much you’re worth. This allows you to set a figure in mind to shoot for during the salary negotiation session.
2) Be confident with the negotiation If you are a key person in your organization making good contribution, you are armed with bullets, and you can ask for more during the negotiation. Don’t worry of losing the job. At the end of the negotiation session, you’ll either get a salary increase or you’ll figure out you’re not in the right organization that can meet your salary expectation. You may want to start to explore other job opportunities.
3) What else besides monetary rewards you should negotiate The remuneration package needs to be evaluated as an overall deal. Don’t leave out rewards such as share options, leave passage, pension plans, bonuses, subsidies, etc. The negotiation can be for a raise of any of these rewards. Other non monetary rewards you can demand are the medical coverage, insurance coverage, annual leave, flexible working hours and company car.
4) Draft a letter to request for a meeting on salary increase Never discuss you salary matter with the boss in an ad hoc manner such as after a meeting. If you want to get good result, write a formal letter to your boss by declaring your purpose and arrange suitable time for a discussion. If you’re having difficulties to get started, you can seek professional help or refer to the proven pay raise letter examples for ideas on the appropriate format and contents.
5) Prepare a package to sell your contribution You need to package and sell your special skills, accomplishments and contributions for your job objectives, and not to forget to emphasize your special achievements.
6) Build good credibility and demonstrate your value The discussion will be very much smoother if you have built good credibility with the company. Holding the meeting at the right time, for example after delivering some good value to the company, will lower the resistance in getting approval for a salary increase. Attend the meeting with confidence and discuss the case as professional as possible. Personal needs such as “I require more money because of my eldest kid is going to college next year” should not be used as a reason to support the pay raise.
7) Ask smart questions and let the employer do the talking Ask intelligent open-ended questions and lure the employer to do the talking. Be a good listener and let the employer bring about giving you what you want. The employer always thinks that their decision is the best, and they strongly believe in it. Don’t challenge their viewpoint, but make them convince your worth and get them to approve your raise.
8) Start negotiation by setting an aggressive goal One of the tactics often use in salary negotiation is to “demand for higher and compromise for lesser.” Get the employer to make the first offer to you before you tell them your target. They may offer more than what you expect by surprise. If you’ve done your homework well on the pay range, you can set your target slightly higher then the upper range. Explain and justify why you’re an outstanding employee.
9) Be prepared to move on for a better job If you can demonstrate to the employer that you are prepared to walk away should the negotiation fails, you have created tremendous power and pressure to make the employer compromises. Never show the employer that you are desperate for the job.
Conclusion The objective of a salary negotiation is to find solutions that are win-win for both parties. To ensure the negotiation is successful, you need to prepare all necessary information, learn negotiation tactics for effective bargaining and set up a face-to-face session to discuss the case professional. If you can show the employer that you are willing to move away, you will have more leverage on your bargaining. If you’re not easily replaceable in your organization, you should feel confident with the negotiation.

Virtual Database

A virtual database, also called a federated database, is a way to view and query several databases as if they were a single entity.
The goal of working in a virtual database is to be able to look at data in a more unified way without having to duplicate it across multiple databases or manually combine the results from multiple queries. In a homogenous environment, virtual databases can help distribute the load of very large databases.
Each component database in the system is completely self-sustained and functional. When an application queries a virtual database, the system figures out which of its component databases contains the data being requested and passes the request to it. The biggest challenge to building a virtual database is that the developer needs to first build a universal data model. The data model serves as a map to every source of data within the company. Finding a single schema that can address all of a company's data needs can be difficult, particularly if data is dirty.
Integrating disparate databases under a centralized console offers several benefits. First, federated databases offer an alternative to merging databases together, which can be a tedious task. Second, they help programmers avoid the tight coupling of applications with legacy databases by eliminating vendor and schema lock-in. Applications can be written to target the intermediary layer - the virtual database - as opposed to a specific database by a specific vendor. Finally, applications need only to be connected to the virtual database in order to work with data from multiple databases.
