How to use your camera phone into a high quality wireless

noreply@blogger.com (Azhar Hussain) — Sat, 12 Sep 2009 20:08:00 +0000

Today I was trying to use my N95 8GB phone's 5 MP camera as a webcam to my laptop. After googling I find Mobiola Web Camera 3. Installing it over laptop is really very easy and after installation it gives u a tiny piece of desktop app with the little sisx application which need to be installed to your smart phone. This sisx should be transferred to the phone through any medium (bluetooth,infra or USB) and install on your mobile right after installation. You can access your phone camera from your laptop. Although result is not as good as 5 MP should be, but still its great to use as it can be use to record the movie in AVI format right onto your PC's hard drive with relatively low size which can be shared through any video sharing apps like Youtube ,facebook etc , and YES you can use it like your natve webcam required at messengers for Video Conference.

Implementation Process of Business Intelligence in an Organization

Potential problems in implementing Business Intelligence

noreply@blogger.com (Azhar Hussain) — Mon, 03 Aug 2009 13:42:00 +0000

User resistance is one big barrier to BI success; others include having to winnow through voluminous amounts of irrelevant data and poor data quality.
The key to getting accurate insights from BI systems is standard data. Data is the most fundamental component of anyBI endeavour. It's the building blocks for insight. Companies have to get their data stores and data warehouses in good working order before they can begin extracting and acting on insights. If not, they'll be operating based on flawed information.

Another potential pitfall is BI tools themselves. Though the tools are more scalable and user friendly than they used to be, the core of BI is still reporting rather than process management, although that's slowly beginning to change. Be careful not to confuse business intelligence with business analytics.
A third impediment to using BI to transform business processes is that most companies don't understand their business processes well enough to determine how to improve them. And companies need to be careful about the processes they choose. If the process does not have a direct impact on revenue or the business isn't behind standardising the process across the company, the entire BI effort could disintegrate. Companies need to understand all the activities that make up a particular business process, how information and data flow across various processes, how data is passed between business users, and how people use it to execute their particular part of the process. And they need to understand all this before they start a BI project, if they hope to improve how people do their jobs.

Concept of Business Intelligence

noreply@blogger.com (Azhar Hussain) — Sun, 02 Aug 2009 13:35:00 +0000

Business intelligence, or BI, is an umbrella term that refers to a variety of software applications used to analyse an organisation’s raw data. BI as a discipline is made up of several related activities, including data mining, online analytical processing, querying and reporting.
Companies use BI to improve decision making, cut costs and identify new business opportunities. BI is more than just corporate reporting and more than a set of tools to coax data out of enterprise systems. CIOs use BI to identify inefficient business processes that are ripe for re-engineering. With today’s BI tools, business folks can jump in and start analysing data themselves, rather than wait for IT to run complex reports. This democratisation of information access helps users back up — with hard numbers — business decisions that would otherwise be based only on gut feelings and anecdotes.
Although BI holds great promise, implementations can be dogged by technical and cultural challenges. Executives have to ensure that the data feeding BI applications is clean and consistent so that users trust it.

What are the challenges when implementing a balanced scorecard?

noreply@blogger.com (Azhar Hussain) — Sun, 02 Aug 2009 13:33:00 +0000

Corporate culture changes, and with change can come fear, especially if it is tied to performance standards. Much of that can be abated if you are honest with stakeholders and employees. It can also be a time-consuming process, taking up to a year to fully implement, although the original estimate from Kaplan and Norton indicated a time of 26 months to implement everything down to the level of individual employees. It also requires full top-level support over a long period of time, during which other priorities and emergencies almost certainly will take centre stage, at least temporarily. And it's certainly not cheap. Depending on the scope of the project, it can cost from thousands to hundreds of thousands of dollars. Costs include team members and time spent, facilitator cost, software licensing costs, installation and testing costs, and annual maintenance and upgrade costs.

Benefits of introducing BI in your company

noreply@blogger.com (Azhar Hussain) — Sat, 01 Aug 2009 13:45:00 +0000

A broad range of applications for BI has helped companies rack up impressive ROI figures. Business intelligence has been used to identify cost-cutting ideas, uncover business opportunities, roll ERP data into accessible reports, react quickly to retail demand and optimise prices.
Besides making data accessible, BI software can give companies more leverage during negotiations by making it easier to quantify the value of relationships with suppliers and customers.Within the walls of the enterprise, there are plenty of opportunities to save money by optimising business processes and focusing decisions. BI yields significant ROI when it sheds light on business bloopers. For example, employees of the city of Albuquerque used BI software to identify opportunities to cut mobile phone usage, overtime and other operating expenses, saving the city $US2 million during three years. Likewise, with the help of BI tools, Toyota realised it had been double-paying its shippers to the tune of $US812,000 in 2000. Companies that use BI to uncover flawed business processes are in a much better position to successfully compete than companies that use BI merely to monitor what's happening.

More tips for getting BI right

Analyse how executives make decisions.
Consider what information executives need in order to facilitate quick, accurate decisions.
Pay attention to data quality.
Devise performance metrics that are most relevant to the business.
Provide the context that influences performance metrics.

How is the balanced scorecard implemented?

noreply@blogger.com (Azhar Hussain) — Sat, 01 Aug 2009 13:31:00 +0000

According to the Balanced Scorecard Institute, it consists of multiple steps:
1. Assess the company's organisational structure
2. Identify strategic themes
3. Define perspectives and strategic objectives
4. Develop a strategy map
5. Derive performance metrics
6. Craft and prioritise strategic initiatives
7. Automate and communicate
8. Cascade the balanced scorecard throughout the organisation
9. Collect data, evaluate and revise

What are the benefits of implementing a balanced scorecard?

noreply@blogger.com (Azhar Hussain) — Fri, 31 Jul 2009 13:27:00 +0000

Major benefits include increased structure and shared objectives; these often lead to greater financial return. It allows organisations to become more functional and enabled. For specific programs, a balanced scorecard can raise the profile of key projects, which can help with funding and internal support. It's also possible to use the strategic map that a balanced scorecard approach creates to help guide programs toward success. And it's catching on.

What is a balanced scorecard?

noreply@blogger.com (Azhar Hussain) — Thu, 30 Jul 2009 13:22:00 +0000

The balanced scorecard methodology, an outgrowth of prior measurement and management methodologies like total quality management (TQM), has existed for decades, but it was formalised in the early 1990s by Robert Kaplan and David Norton. Kaplan and Norton not only gave it a formal name but also put structure around the way organisations can measure how well they are functioning and how to predict future performance.

Basically, it's a way to map and translate complex business information into something that's understandable to everyone. The methodology starts with targets defined by the organisation, followed by scorecard measures. These usually include both corporate targets and business unit targets, which are then honed into individual measures and targets. It's a very flexible approach, designed to be adapted to any organisation's needs. And virtually anything can be measured.

Implementation of Business Intelligence

noreply@blogger.com (Azhar Hussain) — Wed, 29 Jul 2009 13:37:00 +0000

When implementing BI for the companies,first they should analyse the way they make decisions and consider the information that executives need to know for making more confident and more rapid decisions, as well as how they'd like that information presented to them (for example, as a report, a chart, online, hard copy). Discussions of decision making will drive what information companies need to collect, analyse and publish in their BI systems.
Good BI systems need to give context. It's not enough that they report sales were X yesterday and Y a year ago that same day. They need to explain what factors influencing the business caused sales to be X one day and Y on the same date the previous year.
Like so many technology projects, BI won’t yield returns if users feel threatened by, or are sceptical of, the technology and refuse to use it as a result. And when it comes to something like BI, which, when implemented strategically, ought to fundamentally change how companies operate and how people make decisions, CIOs need to be extra attentive to users' feelings.
Seven steps to rolling out BI systems:
1. Make sure your data is clean.
2. Train users effectively.
3. Deploy quickly, then adjust as you go. Don't spend a huge amount of time up front developing the “perfect”
reports because needs will evolve as the business evolves. Deliver reports that provide the most value quickly,and then tweak them.
4. Take an integrated approach to building your data warehouse from the beginning. Make sure you're not locking
yourself into an unworkable data strategy further down the road.
5. Define ROI clearly before you start. Outline the specific benefits you expect to achieve, then do a reality check
every quarter or six months.
6. Focus on business objectives.
7. Don't buy business intelligence software because you think you need it. Deploy BI with the idea that there are
numbers out there that you need to find, and know roughly where they might be.

Concept behind Anonymity

noreply@blogger.com (Azhar Hussain) — Tue, 12 May 2009 14:51:00 +0000

Anonymity:
I can see you hiding in the shadows over there and so can the logs of all the web sites, FTP servers and other nooks and crannies you visit on the web. The sort of information gathered by these logs and which is available to the webmasters of the sites you visit include the address of the previous site you visited, your IP address, your computer's ID name, your physical location and the name of your ISP along with less personal details such as the operating system you're using and your screen resolution. If someone was snooping through your dustbin to gather information on consumer trends or tracking your every move to see where it is you go everyday you wouldn't be too chuffed would you. Well the web is no different, it's still an invasion of privacy and a threat to security and you don't have to put up with it.
Proxy:

Every time you visit a web site, detailed information about your system is automatically provided to the webmaster. This information can be used by hackers to exploit your computer or can be forwarded to the market research departments of consumer corporations who by tracking your activities on the internet are better equipped to direct more relevant spam at you. Your best defence against this is to use what is known as a proxy server, which will hide revealing information from the web sites you visit, allowing you to surf the web anonymously. These work by altering the way in which your browser retrieves web pages or connects to remote servers. With a proxy server set up, whenever you 'ask' IE or Netscape to look at a web page, the request is first sent through an external server which is completely independent of your ISP's servers. This third party server then does the requesting on your behalf so that it appears that the request came from them rather than you and your real IP address is never disclosed to the sites you visit. There is nothing to download and the whole process takes less than a minute.
There are two different ways to use proxy servers and both have their advantages and disadvantages. The first method is to use a web based service. What this involves is visiting the proxy's home page each time you want to browse a web site anonymously. The core component of such a system is the dialog box where you enter the address of the web site you want to visit. Each time you enter the URL of the site you want to browse via the proxy into this box, your personal information, IP address and so on is first encrypted before being sent to the site allowing you to maintain your anonymity.Obviously one disadvantage of using a web based service like Rewebber or Anonymizer, however, is that you have to visit the proxies home page each time you want to surf anonymously. You could choose to select this page as your default home page, but it's still quite awkward if you're forever site hopping at the speed of light. The second main 'con' is that you often have to put up with extra adverts on the pages you visit. These are automatically inserted into the pages by the proxy - they have to pay for service somehow. More sophisticated and convenient solutions are also on offer yet they come with a price tag.
The second method you can use to protect your privacy via a proxy server involves adjusting the settings of your web browser so that you can surf anonymously without having to visit the home page of your proxy each time. To do this you will first need to know the name of your proxy server and the port number it uses. This information can be gleaned from either a public proxy server list or the FAQ referring to a private subscription based service. Once you have the name of the proxy server you wish to use, select 'Internet Options' from the 'Tools' menu of your browser. Now select 'Connections' followed by 'Settings' and tick the 'use a proxy server' check box. To finish the job all you have to do now is enter the name of the server in the 'address' box, the port which it uses in the 'port' box and go forth and surf anonymously.
Free, manual proxy servers as advertised on anonymity sites, if you can find one at all, are likely to be highly oversubscribed, and as a result the speed at which they retrieve web pages can deteriorate. In which case you can go in pursuit of a public proxy server list and select an alternative from it, which can then be set up manually.
however, this method isn't problem free either, so before you get too carried away and go jumping on the anonymity bandwagon there are a few things you should be aware of. It's very easy to use proxies to protect your privacy, but often the disadvantages of using them far out weigh the benefits. You see, the problem is that, like the proxy servers provided Rewebber et al, free, public proxies are nearly all over subscribed and so they can slow down web browsing considerably. Digging out fast reliable proxy servers is an art form in itself and is a skill which takes considerable practice. You could find a list of public proxy servers and then experiment with each one until you find one that runs at a reasonable speed, but this can be very time consuming and frustrating. Instead, your search would be much more efficient if you got a dedicated program to carry out this task for you. There are literally dozens of proxy seeking programs around which can do just that, and many of them are available as freeware. What these do is scan the internet for public proxy servers. These servers are then tested for speed and anonymity (not all of them are truly anonymous, even if they claim to be!) and once you find one which suits your requirements you can select it as your default proxy with the click of a button.
One of the most significant advantages of using an automated tool to locate proxy servers is that you do not have to keep editing your proxy settings manually each time you wish to try out a new one. Instead, what you do is enter 'localhost' or '127.0.0.1' into the 'address' box and '8088' into the 'port' box of your browser's proxy settings menu and then forget about it. All future proxy switching is then orchestrated from within your proxy seeking software, which subsequently relays the information to your browser or whatever type of application you are attempting to make anonymous. For those of you who are curious 'localhost' and the IP address '127.0.0.1' are the names by which every computer on the internet refers to itself.You may find that even when using these programs you have difficulty finding good proxy servers. It is for this reason that many people choose only to use proxy servers temporarily whilst doing something which may land them in trouble with their ISP, or in a worst case scenario with the law. The most obvious example of a situation in which you would want to cover your tracks is when scanning for public FTP servers and subsequently uploading to them. Most other net activities are unlikely to incur serious consequences so under these circumstances you can safely surf the web without a proxy.Before splashing out though it may be worth checking if your current ISP has a proxy server of its own which you can use. These aren't there to help you to commit cyber crimes and get away with it, they actually have a legitimate purpose as well - otherwise they wouldn't exist. You see, proxy servers were originally designed to help speed up web page loading times. Proxy servers contain a cache of all the web pages which have been requested via the browsers of the people using the proxy. When someone surfs the web using a proxy, the proxy first checks to see if it already has a copy of the web page stored in its cache. If this version of the page is bang up to date, it is sent to your computer and appears in your browser. If the page found in the cache of the proxy server is older than the one stored on the server hosting the page, a new request to the web server is made and the page is updated in the cache of the proxy before being sent to you. Because these servers use very fast internet connections they can retrieve web pages at much greater speeds than you can via your modest home setup. If these servers are located physically nearer to your home than the web host servers you wish to retrieve web pages from, the speed at which you browse the web will be accelerated.
Anonymity - Cookies:

One last important point you need to be aware of before jumping in with both feet is that different programs have to be setup in different ways before being able to make external connections via a proxy server. For example, you can surf the web anonymously by modifying the settings in Internet Explorer or Netscape Navigator as explained earlier in this tutorial, but this will only affect your browser. If you then used Flash FXP to copy a batch of 0-day releases from one FTP server to another, this isn't going to protect you in the slightest. What you have to do is enter the name of the proxy server into each application you wish to make anonymous before making any external connections. This can usually be done by browsing through the preferences of your program to see if there is a 'use proxy server' option available. If there is, make sure you use it!
Cookies:

You have little to fear from the edible variety, but the digital ones can be a major threat to your security and privacy. A cookie is a tiny text file (usually less than 1kb in size), which is created and stored on your hard drive whenever you visit a dynamic (or an interactive if you like) web site. These are used to log your personal details so that you can access members only areas of web sites without having to type in a password every time, or to retain your customised settings so that they are available the next time you visit. If you're using a shared computer, anyone who visits the same site that you have previously logged in to can access your accounts. This is particularly worrying if you have entered your credit card details into a form on an e-commerce site. If your browser is set to automatically fill in these details whenever youreturn to a previously visited site, this information could be clearly visible - you don't need me to explain the problems this could entail.
The solution to this problem is to delete any cookies which contain sensitive data once you have completed your transactions. Your cookies will be stored in a different place depending on which operating system you are using so you will have to use your detective skills to find them. As an example, in Windows XP they are located in your 'c:\Documents and Settings\Kylie Minogue\Cookies' directory (that is if your name is Kylie Minogue. Mine isn't in case you're wondering!). If you look in this directory, in some cases it is easy to identify which cookie is associated with which web site, but in other cases it's not so obvious. The cookie which was created when you visited Yahoo.com to check your email may be called kylie minogue@yahoo.txt for example. Unfortunately some cookies refer to the IP address of the site you visited and so look more like kylie minogue@145.147.25.21. These cookies can be selectively deleted one at a time if it's obvious which ones are causing a threat to your security, or you can just wipe out the whole lot in one fell swoop and have them recreated as and when they are required. However, ifyou're really struggling to find your cookie jar, you could delete your cookies via your browser's tool bar instead. In Internet Explorer this can be done through the 'Tools>Internet Options' menu items.
If all this sounds like too much hassle, you can always find a labour saving program which will be happy to take the job off your hands. These 'cookie crunching' programs allow you to be more selective when editing, viewing and deleting cookies from your system, and some of them will even prevent cookies from being created in the first place.

Anonymity of Proxy

noreply@blogger.com (Azhar Hussain) — Mon, 11 May 2009 14:46:00 +0000

The exchange of information in Internet is made by the "client - server" model. A client sends a request (what files he needs) and a server sends a reply (required files). For close cooperation (full understanding) between a client and a server the client sends additional information about itself: a version and a name of an operating system, configuration of a browser (including its name and version) etc. This information can be necessary for the server in order to know which web-page should be given (open) to the client. There are different variants of web-pages for different configurations of browsers. However, as long as web-pages do not usually depend on browsers, it makes sense to hide this information from the web-server.
What your browser transmits to a web-server:a name and a version of an operating systema name and a version of a browserconfiguration of a browser (display resolution, color depth, java / javascript support, ...)IP-address of a clientOther information
The most important part of such information (and absolutely needless for a web-server) is information about IP-address. Using your IP it is possible to know about you the following:a country where you are froma cityyour provider?s name and e-mailyour physical address
Information, transmitted by a client to a server is available (accessible) for a server as environment variables. Every information unit is a value of some variable. If any information unit is not transmitted, then corresponding variable will be empty (its value will be undetermined).
These are some environment variables:
REMOTE_ADDR ? IP address of a client
HTTP_VIA ? if it is not empty, then a proxy is used. Value is an address (or several addresses) of a proxy server, this variable is added by a proxy server itself if you use one.
HTTP_X_FORWARDED_FOR ? if it is not empty, then a proxy is used. Value is a real IP address of a client (your IP), this variable is also added by a proxy server if you use one.
HTTP_ACCEPT_LANGUAGE ? what language is used in browser (what language a page should be displayed in)
HTTP_USER_AGENT ? so called "a user?s agent". For all browsers this is Mozilla. Furthermore, browser?s name and version (e.g. MSIE 5.5) and an operating system (e.g. Windows 98) is also mentioned here.
HTTP_HOST ? is a web server?s name
This is a small part of environment variables. In fact there are much more of them (DOCUMENT_ROOT, HTTP_ACCEPT_ENCODING, HTTP_CACHE_CONTROL, HTTP_CONNECTION, SERVER_ADDR, SERVER_SOFTWARE, SERVER_PROTOCOL, ...). Their quantity can depend on settings of both a server and a client.
These are examples of variable values:
REMOTE_ADDR = 194.85.1.1HTTP_ACCEPT_LANGUAGE = ruHTTP_USER_AGENT = Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)HTTP_HOST = www.webserver.ruHTTP_VIA = 194.85.1.1 (Squid/2.4.STABLE7)HTTP_X_FORWARDED_FOR = 194.115.5.5
Anonymity at work in Internet is determined by what environment variables "hide" from a web-server.
If a proxy server is not used, then environment variables look in the following way:
REMOTE_ADDR = your IPHTTP_VIA = not determinedHTTP_X_FORWARDED_FOR = not determined
According to how environment variables "hided" by proxy servers, there are several types of proxiesTransparent Proxies
They do not hide information about your IP address:
REMOTE_ADDR = proxy IPHTTP_VIA = proxy IPHTTP_X_FORWARDED_FOR = your IP
The function of such proxy servers is not the improvement of your anonymity in Internet. Their purpose is information cashing, organization of joint access to Internet of several computers, etc.Anonymous Proxies
All proxy servers, that hide a client?s IP address in any way are called anonymous proxies
Simple Anonymous Proxies
These proxy servers do not hide a fact that a proxy is used, however they replace your IP with its own:REMOTE_ADDR = proxy IPHTTP_VIA = proxy IPHTTP_X_FORWARDED_FOR = proxy IP
These proxies are the most widespread among other anonymous proxy servers.
Distorting Proxies
As well as simple anonymous proxy servers these proxies do not hide the fact that a proxy server is used. However a client?s IP address (your IP address) is replaced with another (arbitrary, random) IP:
REMOTE_ADDR = proxy IPHTTP_VIA = proxy IPHTTP_X_FORWARDED_FOR = random IP addressHigh Anonymity Proxies
These proxy servers are also called "high anonymity proxy". In contrast to other types of anonymity proxy servers they hide a fact of using a proxy:
REMOTE_ADDR = proxy IPHTTP_VIA = not determinedHTTP_X_FORWARDED_FOR = not determined
That means that values of variables are the same as if proxy is not used, with the exception of one very important thing ? proxy IP is used instead of your IP address.Summary
Depending on purposes there are transparent and anonymity proxies. However, remember, using proxy servers you hide only your IP from a web-server, but other information (about browser configuration) is accessible!

What is Spyware?

noreply@blogger.com (Azhar Hussain) — Sat, 09 May 2009 14:27:00 +0000

There are a lot of PC users that know little about "Spyware", "Mal-ware", "hijackers", "Dialers" & many more. This will help you avoid pop-ups, spammers and all those baddies.
What is spy-ware?

Spy-ware is Internet jargon for Advertising Supported software (Ad-ware). It is a way for shareware authors to make money from a product, other than by selling it to the users. There are several large media companies that offer them to place banner ads in their products in exchange for a portion of the revenue from banner sales. This way, you don't have to pay for the software and the developers are still getting paid. If you find the banners annoying, there is usually an option to remove them, by paying the regular licensing fee.
Known spywaresThere are thousands out there, new ones are added to the list everyday. But here are a few:Alexa, Aureate/Radiate, BargainBuddy, ClickTillUWin, Conducent Timesink, Cydoor, Comet Cursor, eZula/KaZaa Toptext, Flashpoint/Flashtrack, Flyswat, Gator, GoHip, Hotbar, ISTbar, Lions Pride Enterprises/Blazing Logic/Trek Blue, Lop (C2Media), Mattel Brodcast, Morpheus, NewDotNet, Realplayer, Songspy, Xupiter, Web3000, WebHancer, Windows Messenger Service.

23 Tips to Speed Up your Windows XP Performance

noreply@blogger.com (Azhar Hussain) — Fri, 08 May 2009 14:18:00 +0000

Given below are the 23 tricks that will enhance the performance and reliability of your Windows XP OS.

Best of all, most of them will cost you nothing.

1-To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.
2- If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.
3- Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.
4- Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.
The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.
Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.
Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.
5- Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.
6- Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.
7- Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.
8- In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.
9- Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.
10- Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.
11- Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.
12- Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.
13- Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.
14- If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.
15- Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.
16- Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.
17- Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.
18- Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.
19- Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.
20- If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.
21- Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.
22- If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.
23- At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.

Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Setting up a Project Office

noreply@blogger.com (Azhar Hussain) — Mon, 04 May 2009 13:11:00 +0000

1. Introduction
A Project Office is a department responsible for improving project management within an organization. It's a permanent department within an organization, not a temporary function. It's there to coordinate projects and ensure they have the right tools, standards, methodologies and templates needed to boost their chances of success.
2. Types of Project Office
There are 3 types of Project Offices namely
The Supportive Project Office:This is the most common type of Project Office. Its purpose is to empower Project Managers and teams to deliver projects. It doesn't control or direct projects. Instead it supports projects by offering training, mentoring, administration and reporting.
The Controlling Project Office: Supportive services may not be enough to put projects back on track. By offering controlling services (such as project reviews, audits and assessments), the Project Office can influence project delivery. It may also enforce project standards and processes to minimize project risk.
The Directive Project Office: The least common, but sometimes most effective type of Project Office, is one that directs projects. Here, the Project Managers report to the Project Office, which is directly responsible for the success of each project. This helps to group the project work within an organization to being under one department-the Project Office.
3. Suitable Project Office
Read these tips to decide which type of Project Office is best for you:

If you're implementing a Project Office for the first time, then the "Supportive" model is best. It helps you add value to projects by offering reporting, training and monitoring services, without taking on the responsibility for the projects themselves.
If you have an established Project Office and you want to ensure that projects are independently assessed, then the "Controlling" model is best. You can directly influence the success of projects, as well as implement best practices, standards and tools.
If your organization has a small set of high risk projects at any one time, then usually the "Directive" model is best.

4. Responsibilities of a Project Office:
The Project Office is responsible for:

Resolving common project problems
Implementing the right project tools
Monitoring and reporting on status, and
Improving project success rates.

5. How to Setup a Project Office
Take these 4 steps:
Project Office Initiation: Define the role of the Project Office, obtain clear sponsorship and document the Project Office Charter. Seek funding and appoint a Steering Committee to oversee the operation. Appoint staff, obtain a premise and install the office furniture, computer equipment and communications. Whew!
Project Office Planning: Then select the project software you need to run it. Procure and implement the tools in your Organization. Then create a detailed plan outlining the Project Office services you're going to perform (such as project reporting and auditing).
Project Office Execution: You're now ready to offer your supportive, controlling or directive services to project teams. This will include offering training, mentoring and support. It may also include reviews and assessments or the management of special projects directly.
Project Office Improvement: As it's an on-going operation, you need to constantly improve the level of service offered by your Project Office.
If you take these steps to set up your Project Office then you will deliver more projects on time and under budget.

SQL : Joins

noreply@blogger.com (Azhar Hussain) — Sun, 26 Apr 2009 09:51:00 +0000

Introduction:
A join is used to combine rows from multiple tables. A join is performed whenever two or more tables is listed in the FROM clause of an SQL statement.
There are different kinds of joins. Let's take a look at a few examples.
Inner Join (simple join)
Chances are, you've already written an SQL statement that uses an inner join. It is the most common type of join. Inner joins return all rows from multiple tables where the join condition is met.
For example
SELECT suppliers.supplier_id, suppliers.supplier_name, orders.order_dateFROM suppliers, ordersWHERE suppliers.supplier_id = orders.supplier_id;

This SQL statement would return all rows from the suppliers and orders tables where there is a matching supplier_id value in both the suppliers and orders tables.
Let's look at some data to explain how inner joins work:

We have a table called suppliers with two fields (supplier_id and supplier_ name).It contains the following data:

We have another table called orders with three fields (order_id, supplier_id, and order_date).It contains the following data: If we run the SQL statement below:
SELECT suppliers.supplier_id, suppliers.supplier_name, orders.order_dateFROM suppliers, ordersWHERE suppliers.supplier_id = orders.supplier_id;

Our result set would look like this:

The rows for Microsoft and NVIDIA from the supplier table would be omitted, since the supplier_id's 10002 and 10003 do not exist in both tables.

Outer Join
Another type of join is called an outer join. This type of join returns all rows from one table and only those rows from a secondary table where the joined fields are equal (join condition is met).
For example,

select suppliers.supplier_id, suppliers.supplier_name, orders.order_datefrom suppliers, orderswhere suppliers.supplier_id = orders.supplier_id(+);

This SQL statement would return all rows from the suppliers table and only those rows from the orders table where the joined fields are equal.
The (+) after the orders.supplier_id field indicates that, if a supplier_id value in the suppliers table does not exist in the orders table, all fields in the orders table will display as in the result set.

The above SQL statement could also be written as follows:
select suppliers.supplier_id, suppliers.supplier_name, orders.order_datefrom suppliers, orderswhere orders.supplier_id(+) = suppliers.supplier_id
Let's look at some data to explain how outer joins work:
We have a table called suppliers with two fields (supplier_id and name).It contains the following data:

If we run the SQL statement below:
select suppliers.supplier_id, suppliers.supplier_name, orders.order_datefrom suppliers, orderswhere suppliers.supplier_id = orders.supplier_id(+);
Our result set would look like this:

The rows for Microsoft and NVIDIA would be included because an outer join was used. However, you will notice that the order_date field for those records contains a value.

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level

noreply@blogger.com (Azhar Hussain) — Sun, 26 Apr 2009 08:39:00 +0000

You may get this error when trying to browse an asp.net application. The debug information shows that

"This error can be caused by a virtual directory not being configured as an application in IIS."

This error occurs probably in these 2 scenarios.

1- When you create an new web application using visual studio.net, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error. The debug information you get as mentioned above, is applicable to this scenario. To resolve it, Right Click on the virtual directory - select properties and then click on "Create" next to the "Application" Label and the textbox. It will automatically create the "application" using the virtual directory's name. Now the application can be accessed.

2. When you have sub-directories in your application, you can have web.config file for the sub-directory. However, there are certain properties which cannot be set in the web.config of the sub-directory such as authentication, session state (you may see that the error message shows the line number where the authentication or sessionstate is declared in the web.config of the sub-directory). The reason is, these settings cannot be overridden at the sub-directory level unless the sub-directory is also configured as an application (as mentioned in the above point). Mostly we have the practice of adding web.config in the sub-directory if we want to protect access to the sub-directory files (say, the directory is admin and we wish to protect the admin pages from unathorized users). But actually, this can be achieved in the web.config at the application's root level itself, by specifing the location path tags and authorization, as follows:-

But if you wish to have a web.config at the sub-directory level and protect the sub-directory, you can just specify the Authorization mode as follows:-

By doing that you can protect the sub-directory from unauthorized access.

SQL : Select Query : Distint Clause

noreply@blogger.com (Azhar Hussain) — Sat, 25 Apr 2009 09:46:00 +0000

Introduction:
The DISTINCT clause allows you to remove duplicates from the result set. The DISTINCT clause can only be used with select statements.

The syntax for the DISTINCT clause is:
SELECT DISTINCT columnsFROM tablesWHERE predicates;

Example #1
Let's take a look at a very simple example.
SELECT DISTINCT categoryFROM ebooks;

This SQL statement would return all unique categories from the ebooks table.

Example #2
The DISTINCT clause can be used with more than one field.
For example:

SELECT DISTINCT category, publisherFROM ebooks;

This select statement would return each unique category and publisher combination. In this case, the distinct applies to each field listed after the DISTINCT keyword.

SQL : Select Query

noreply@blogger.com (Azhar Hussain) — Sat, 25 Apr 2009 09:35:00 +0000

Introduction:
The SELECT query/statement allows to retrieve records from one or more tables in database.

The syntax for the SELECT statement is:
SELECT [ columns] FROM [tables] WHERE [predicates];

Example #1
Let's take a look at how to select all fields from a table.
SELECT *FROM ebooks WHERE author = 'Azhar';

In our example, we've used * to signify that we wish to view all fields from the ebooks table whose author is 'Azhar'.

Example #2
You can also choose to select individual fields as opposed to all fields in the table.
For example:
SELECT name, ISBN FROM ebooks WHERE ebookid > 1000;
This select statement would return all ebooks' name and their respective ISBN values from the ebooks table where the ebookid value is greater than 1000.

Example #3
You can also use the select statement to retrieve fields from multiple tables.
SELECT category.name,ebooks.ebookid, ebooks.name FROM category,ebooks WHERE category.categoryid=ebooks.categoryid;
The result set would display category name and and ebooks lies in the category
