Backup is the most excellent method to prevent data loss and safeguard your valuable data. And Creating Image of the hard disk is the best option to Secure data. Image is an exact replica of source media, which can be stored on any internal or external storage device. In Mac OS X, you can create image of your hard drive using Disk Utility, without investing on any expensive third-party utility. You can easily perform Mac file Recovery using the hard diskimage, in case of hard disk failure or data loss.

Disk Utility is originally a disk repair tool, which is used to check the integrity and consistency of your Mac OS X hard drive. You can access it from: User-> Applications-> Utilities-> Disk Utility. It is quite effective and easy to use. You can create image of Mac OS X hard drive using Disk Utility through the underwritten steps:

Start your Mac OS X machine using Boot DVD. To do so, insert boot DVD in the DVD drive and hold the C key when your system boots.

On the next screen, select your language. This is a step to get into the Disk Utility. When you see the menu bar, choose Disk Utility from Utilities menu.

When the Disk Utility program opens, select the source drive. It is the media that you want to create image of. After selecting the source drive, specify a destination drive to store disk image on it.

Click Restore button. Let the process complete and you get an absolute copy of your Mac OS X hard drive.

After completion of the process, reboot your system and you are ready to go.

The image file works as a separate hard drive volume, which can be accessed independently. When you face system failure or system crash like situations, which causes data loss, it is possible to restore data from image and perform File Recovery Mac.

However, if you do not create image of your hard drive, or image itself gets damaged, you can not restore data from it. In such cases, Mac File Recovery Software come to your rescue, if any data loss occurs.

The applications are particularly designed to methodically scan entire hard drive and extract all inaccessible data from it. Mac Recovery applications come equipped with interactive user interface to offer easy recovery.

Stellar Phoenix Mac Data Recovery software recovers lost, missing, inaccessible, and deleted data from Mac hard drive and other supported storage media. The software works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. It salvages data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

As we have seen in my previous overview of the Windows registry, any computer program or application, before committing data to the registry, must open a key. In order to succeed in such a task, the program or application must provide a handle to another key in the registry that is already opened. Keys that are always open are defined by the system.

These predefined keys are fundamentally acting as a registry navigation system for programs and applications and also as a reference and to make possible the development of tools that allow system administrators to access the registry and manipulate different types of data. Applications that commit data to the registry should always operate within the predefined keys framework in order to allow administrative tools to find and manipulate new data. Ultimately a program or an application uses handles to these predefined keys as a door to the registry.

Here is a brief description of these handles:

HKEY_CLASSES_ROOT:
All registry entries and data within this key are documents type definitions and properties associated with those types. This key also insures backward compatibility with the historical Windows 3.1 registration database for storage of Dynamic Data Exchange also known as DDE and OLE or Object Linking and Embedding which are now obsolete technologies.

HKEY_CURRENT_CONFIG:
Contains details about the current hardware configuration of the local computer system. These details describe only the difference between the current hardware configuration and the standard hardware configuration which is stored within the software and system keys of HKEY_LOCAL_MACHINE

HKEY_CURRENT_USER:
Registry data stored under this key defines the preference of the current user. These preferences include environmental variables, program groups, applications preferences, printers, network connections, etc. Within this key, software vendors store the current user preferences related to their applications. As an example, Microsoft creates two sub-keys: Software and Microsoft with each Microsoft application creating their own sub-keys below the Microsoft key.

HKEY_LOCAL_MACHINE:
Entries under this key identify the physical state of the system. These include data regarding system memory, bus type and installed software and hardware components. Other related sub-keys reference current configuration data, plug and play descriptors of all the hardware ever installed listed in the Enumerator branch, network log in and security information and software pointers such as server names and locations and all other info related to the system.

HKEY_PERFORMANCE_DATA:
Registry data under this key make possible to access performance data. As previously described, this data is not actually stored in the registry rather the registry functions allow the system to perform performance data collections from its source.

HKEY_USERS:
All entries subordinate to this node classify user configuration for new users and for the current user on the local machine.

To have a peek at the above structure in real life, all you have to do is click on the Start button of your PC, select Run. Type in “regedit” or “regedt32″ and hit the OK button. The registry editor will open allowing you to navigate the registry tree structure. Use the plus signs next to the handles to expand them and see what is inside.

A word of warning: take a good look around, but be careful not change or delete anything. Making manual changes to the registry should be left to experienced technicians as even a small mistake can cause system issues and even stop the system form working altogether, leaving you with an inoperable computer and the only alternative of re-installing and re-configuring the operating system and all your programs from scratch…ouch! Of course, if you do not want to get your hands dirty, you can always get a registry cleaner and optimizer application to do the hard work for you to fix, optimize and protect your system from any future disaster.

If you wish to learn more about the Windows registry and how to clean it and optimize it by using a registry cleaner application for lightning fast performance, visit .

Cloud computing is an internet based development and utilizes computer technology to the core. In model, it is a pattern budge whereby aspects are abstracted from the customers who no longer require awareness of, proficiency in or organize over the technology communications ‘in the cloud’ that holds them. It usually engages the stipulation of animatedly scalable and frequently virtualized sources as an overhaul over the internet. Cloud computing technology swanks all the profits of multitenancy, including reliability, built-in security, upgradeability and ease of utilize.

The term cloud is utilized as a metaphor for the internet, established on how the internet is described in computer network diagrams and is a generalization of the fundamental communications it covers. Usual cloud computing services offer common business applications online that are got from a web browser, while data and the software are stacked away on the servers.

These services are generally separated into three classes: platform as a service (PaaS), infrastructure as a service (IaaS) and software as a service (SaaS). The name cloud computing is enthused by the cloud symbol that is frequently utilized to symbolize the internet in diagrams and flow charts. In universal, cloud computing clients do not possess the substantial infrastructure, instead shunning money spending by renting custom from a third party giver. They devour sources as an overhaul and forfeit only for resources that they utilize.

Numerous cloud computing presenting make use of the usefulness computing form which is similar to how conventional usefulness services (such as electricity) are inspired, while others bill on a contribution source. Partaking ‘perishable and intangible’ computing power among several tenants can recover consumption rates, as servers are not unreasonably left inactive (which can diminish costs considerably while raising the speed of application development). A side effect of this advance is that the overall computer custom increases significantly, as consumers do not have to engineer for peak load edges. In addition, ‘raised soaring speed bandwidth creates it probable to obtain the similar response times from federal infrastructure at new sites.

Cloud computing abusers can keep away from money expenditure on software, hardware and overhauls when they forfeit a giver only for what they utilize. Consumption is generally billed on a usefulness (e.g. reserves consumed like electricity) or subscription (e.g. time-based like a newspaper) origin with tiny or no sincere cost. A small number of cloud suppliers are at present opening to proffer the service for a flat monthly charge as opposed to on a usefulness billing origin.

Other advantages of this time sharing style approach are allocated infrastructure and costs, low barriers to entry, low management overhead and immediate access to a plank range of applications. The server’s layer consists of computer hardware and computer software products that are specially considered for the rescue of cloud services.

Cloud architecture, the structures architecture of the software systems engaged in the rescue of cloud computing, contains hardware and software considered by a cloud architect who usually toils for a cloud integrator. It naturally engages numerous cloud elements communicating with each other over application programming interfaces, typically web services. This intimately matches the UNIX attitude of having numerous programs every one doing one thing fine and functioning together over general interfaces. Difficulty is proscribed and the resulting systems are more controllable than their monolithic complements. Cloud architecture expands to the customer, where software applications or web browsers are right of entry to these cloud applications.

Cloud storage architecture is slackly coupled, where metadata actions are centralized altering the data nodes to scale into the hundreds, every one separately rescuing data to users or applications. Cloud computing is generally classified into three types; external cloud or public cloud, hybrid cloud and the private cloud. A public cloud renders services to anybody on the internet. A hybrid cloud can depict form blending a local piece of equipment, such as a plug computer with cloud services. A private cloud is a data center or a proprietary network that provisions hosted services to a restricted number of people. Cloud computing is a marvel for online business applications.

What is Adware?
Adware, short for advertising-supported software, is a general term used to describe the hidden file accompany with any legitimate software package which automatically and secretly plays, displays, downloads, installs advertisement to a computer and hides in the background after the software is installed on it or while the application is being used. Some types of adware are also classified as spyware because they always intend to attach themselves to the system in nefarious ways and track, collect or sand user’s vital or sensitive information, like passwords of email addresses, ID codes and credit card numbers, your Internet habits to a third party without your knowledge for illegal commercial gains applying with animation or flickering banners. Adware may add mysterious links or additional applications to your favorites and desktop, or often change your home page and your search engine to sites that make profits from various advertisers without appropriately obtaining your consent. This income is dependent on the amount of people visit the adware site, or the amount of people click on the links or advertisements at the site. Ads may not hurt your PC by themselves but they are regarded as an annoyance or distraction when they pop up.

How to Prevent Adware Problems

1. Check and make sure the programs you install don’t contain adware. Adware often supposedly hides itself in some legitimate freeware applications on purpose to secretly attach into your system and integrate the animation or flickering banners into your system for commercial gains. Be aware of the latest downloads before installation and make sure that they must come from the trusted sources. Check your favorite search engine such as Google (especially in the Google groups section) to be sure other people are not having problems with it. If many people in group discussions are trying to remove the software, it is not likely to be safe.

2. Install a pop-up blocker to prevent adware and spyware pop-up windows. The most effective way of blocking various kinds of adware and spyware off the network is applying a powerful adware removal tool. A powerful adware remover offers you with professional service to easily detect and remove Spyware, Adware, Keyloggers, Trojans, Worms, Hijackers, Rootkits, Password Stealers, Tracking Threats, Rogue Antispyware and other Malware attacks that can slow down your computer, download and display annoying pop-up ads, modify and control your system settings, or tracks your private or sensitive information without your consent. QuuSoft AntiSpyware serves as a comprehensive, automatic, and self-updating PC security service that will scan your computer for threats and report the detection, if found, in a manner that is easy to read for any computer user. Every detected item is marked with specific security level and classification, which make it easy to decide whether the item should be removed or not.

3. Regularly Update Your Adware Removal Tool. To keep your adware removal tool up-to-date is of vital importance for keeping itself to be effective due to the fact that thousands of adware are supposedly to be developed day after day. When you open your adware removal tool up-to-date to look for a button or tab to update the malware database and do this on a regular monthly basis before scanning your system.

The short answer is “As safe as you need them to be”. Web based issue tracking systems replaced proprietary and ‘server centric’ issue tracking tools in the late 1990s and early 2000s because they provided greater convenience. It was possible to have users report their issues through web based forms rather than call a technician and explain over the phone, then have the tech enter things into a proprietary database.

This resulted in more technician time being used to manage issues and less time spent on record keeping, and has been a boon to development shops the world over ever sense. However, one of the chief concerns people have before making the switch is one of security.

Part of this question stems from a very odd aspect of business – the need to treat every kind of data about their product as proprietary or secret. As the old chestnut goes, having an issue tracking database that’s on the web means that your competitors can use it to steal your customers away. Or, when software is in development, it’s possible for source code to be smuggled out through a web based bug tracking tool.

Interestingly enough, when exposed as such, a lot of these concerns evaporate when compared to the increased customer responsiveness that an open architecture creates. Once businesses realize that it’s the customer’s experience after the sale that they’re selling, not the contents of a shrink wrapped box, this attitude tends to evaporate.

All that said, security issues are important – you will want user authentication on whatever web based issues tracking system you implement, if only to authenticate privileged users from unprivileged ones, and you’ll need to be able to track issues from their point of origin (the original submitter) to the final resolution.

If the data that’s being tracked is proprietary, you’ll need to ensure that your vendor for web based issue tracking is able to handle HTTPS traffic as well as straight HTTP; this, fortunately, is a standard feature for most web based issue tracking tools and many internal bug tracking tools.

If you’re using an internal bug tracking tool that doesn’t support HTTPS, you can restrict the number of IP addresses that can access it, or, if your organization already uses it, utilize virtual private networking (VPN) to allow users to get at it securely.

Time synchronisation plays an ever more important role in the modern world with more and more technologies reliant on accurate and reliable time.

Time synchronisation is not just important but can also be crucial in the safe running of systems such as air traffic control that simply couldn’t function without accurate synchronisation. Think of the catastrophes that could happen in the air of aircraft were out of synchronisation with each other?

In global commerce too accurate and reliable time synchronisation is highly important. When the world’s stock markets open in the morning and traders from across the world buy stock on their computers. As stock fluctuates second by second if machines are out of synchronisation it could cost millions.

But synchronisation is also imperative in modern computer networking; it keeps systems secure and enables proper control and debugging of systems. Even if a computer network is not involved in any time sensitive transactions a lack of synchronisation can leave it vulnerable to malicious attacks and can also be susceptible to data loss.

Accurate synchronisation is possible in computer networking thanks to two developments: UTC and NTP.

UTC is a timescale -coordinated universal time, it is based on GMT but is controlled by an array of atomic clocks making it accurate to within a few nanoseconds.

NTP is a software protocol – Network Time Protocol, designed to accurately synchronise computer networks to a single time source. Both of these implementations come together in a single device which is relied upon the world over to synchronise computer networks – the NTP server.

An NTP time server or network time server is a device that receives the time from an atomic clock, UTC source and distributes it across a network. Because the time source is continually checked by the time server and is from an atomic clock it makes the network accurate to within a few milliseconds of UTC providing synchronisation on a global scale.

Richard N Williams is a technical author and specialist in atomic clocks, telecommunications, NTP and network time synchronisation helping to develop dedicated NTP clocks. Please visit us for more information about a Galleon ntp server or other ntp server solutions.

The explosion in Internet use has brought with it the very real threat of viruses that can attack the unwary user. Viruses come in many forms – installers, Trojans and worms all of which can affect the performance of your computer and your privacy seriously. Viruses affect the computer either by corrupting programs or by replicating themselves and denying resources to legitimate programs. Trojans usually come disguised as something desirable and are activated when you try to open or run them. Worms and some Trojans may send themselves to people in your address book in emails, without your knowledge.

Even though the threat posed by viruses is serious, a few precautions taken in time can help you protect and sanitize your computer against viruses.

1. Browse with Caution – Most viruses enter your computer as a result of clicking on pop ups or other links in websites that are not trustworthy. Do not follow links or click on pop ups that could install viruses on your computer.

2. Open Emails Cautiously – At times, even if the subject is innocuous, emails can contain links that lead to a virus entering your computer. If the email is not from a trusted source, treat it with caution.

3. Open Email Attachments with Care – The attachment that the email urges you to open may contain a virus! Make sure your mail manager allows you to preview the type of file (.exe, .com, .vbt in attachments are probably viruses. The same goes for screensaver programs that come to you unsolicited).

4. Installing downloaded programs – Programs downloaded from the Internet can pose a serious threat to your computer. Make sure that the program you have downloaded is from a trusted site or has a certificate issued by a trusted certifying authority.

5. Firewall – There are several firewall software packages available that allow you to prevent unauthorized access to your computer that could be initiated by an infected system.

6. Antivirus – A good antivirus package residing in your computer can be the best protection you can have against viruses. Choose an antivirus package that can comprehensively defend itself against viruses.

7. Regular Virus Scan – The mere presence of anti-virus software in your computer is not enough. Scanning of your computer for viruses must be done on a regular basis to locate and isolate viruses.

8. Update the Anti-Virus – It is very important to update the anti-virus program itself periodically. New viruses are introduced every day and the manufacturers of the anti-virus software update the virus database and capabilities of the anti-virus program regularly.

9. Update windows and all other software – Do not forget to update the Operating System and other software regularly as they are frequently patched to overcome security loopholes and vulnerabilities.

10. Removable Media – Removable media like floppies and USB drives are a major factor facilitating spreading of viruses. Use only trusted devices on your computer.

The Internet is not a secure environment, therefore it’s important to have software that prevents data theft. Hackers are able to get into your computer remotely through back doors on your PC and security holes that exist in just about every program. You must remember that since human beings are the ones programming any software, there will always be breaches in it, and certain individuals that would like to take advantage. But hackers are not the only concern if you have valuable data on your PC. Aside from the Internet, your computer can be stolen and someone might directly copy everything that’s important. This is the where software that prevents data theft is worth more than money alone.

Rocket Software SecurityVault Enterprise Edition is a program that prevents this happening, enabling businesses to prevent unauthorized users from accessing files on stolen laptops and mobile memory devices. Here is how Rocket CEO Andy Youniss describes the situation: “Employees are increasingly using computers and mobile storage devices to store confidential corporate information, but data thefts that occur as a result of lost and stolen laptops represent a major source of loss of information confidentiality. The bottom line is that no matter how good your firewall may be, it can’t protect offline and mobile data. Rocket SecurityVault Enterprise Edition protects information that firewalls can’t.”

Software that prevents data theft works in the following way. The application disables unauthorized users from accessing files by creating a virtual hard drive with hidden content. The content is only visible to registered users with the right password. The advantage is that besides the fact that the hidden files can’t be accessed, no one even knows that a password exists or that there any hidden files.

So basically, anti-data theft programs work by creating secure “lockboxes” – password protected containers of information. When the user opens the lockbox, a new driver letter automatically shows up in the operating system, so you can check the content in “My Computer”. And the opposite, when locked, the drive letter is removed.

Folder Castle is also among the best software solutions for preventing data theft. This product protects your files and folders with a password, therefore a user that’s not authorized won’t even notice the existence of your information. Folder Castle hides and encrypts your confidential and sensitive files and folders on your computer. The unique thing about FolderCastle is that it doesn’t move the files to a secret folder but hides them in a way that they can’t be seen in Windows Explorer or any other file manager on your PC. And there is also a Stealth mode in which nobody will even know that the program is installed, and protected data is stored on the computer. Stealth mode removes all signs of Folder Castle installation and activity. There is also the option of encrypting the data.

If you have data on your PC(s) that you consider worth protecting then software that prevents data theft should be considered as important as your anti virus package. This is a crucial investment, not simply an optional extra.

Processor and ram

For the majority of PC users, the most important computer components to consider are the Processor and the RAM. The processor is the brain of a computer. It controls and manages all the activities of a computer. The processor is a busy component and it needs a “work area” to do it’s job. The processor uses RAM (random access memory) as a rapid temporary storage area in which to store its work. To cut a long story short, you can upgrade your processor and / or RAM to significantly increase the speed of a PC.

Operating system

There are several operating systems available for people to use. MSDOS, Linux, Mac, BeOS are a few to mention but for most, Microsoft Windows is the most common. Although we still encounter some older Windows machines (95, 98 etc) the majority of users are using Windows XP. So whether you are considering upgrading to XP or indeed upgrading from XP to the new Vista operating system you must first consider the computer’s specifications. Make sure that your machine has the hardware to run the new software. From experience we find that realistically a machine must have 2.5 times the stated minimum requirements in order to smoothly run a Windows operating system. For the moment we advise to stick with Windows XP until the teething problems with Vista are resolved.

Input and output devices

An input device is any device that sends information to a machine (Scanner, light pen, keyboard etc) On the other hand, an output device is any device that sends information from a machine to the outside world (Speakers, monitor, printer etc) Adding peripherals such as printers, scanners, iPods, cameras etc, to a computer is very common these days. If a device is plug and play then loading the device is as simple as just connecting it. However if the device is non-plug and play then you will have to load a specific device driver to enable the computer to run that device. Device drivers can usually be found on an CD that came with the device. However check the manufacturers website for the most up to date version. Please be aware that there are many devices still not compatible with Vista.

Windows updates

Ok, so you have a computer with good hardware that easily runs your operating system, What’s next? Like any operating system, Windows is not perfect. Over time, security holes are found in the operating system. These security holes are used by worms, viruses and hackers to compromise your system. In an effort to patch these security holes, Microsoft releases updates. It is vital that computers are kept up to date with the most recent update releases. The first time you update your computer it may take a long time, especially if you have to download service packs. However this time is well spent and it is possible to set your computer to automatically retrieve and install updates when they are released. Updates are only available once you have verified that your copy of Windows is licensed.

Office applications

If you buy a Microsoft computer without Microsoft Office, it will most likely come with Microsoft Works loaded. This will allow you to create letters and spreadsheets. However it does not have a lot of the features that come with Microsoft Office. The most common used applications in Microsoft Office are Word (Word Processor), Excel (Spreadsheets), Access (Database), PowerPoint (Presentation) and Outlook (Email Client). The most common version of Office at the moment is 2003 however the 2007 is becoming more popular. An issues exists where Office 2007 saves its documents as a .docx file. This is not compatible with Office 2003. A converter is available for download on the Microsoft Website. Also, check out Open Office. It is a free alternative to Microsoft Office.

Firewalls

A firewall is either a hardware or software device that protects a computer from outside menaces. Any machine connected directly to the internet must have a firewall. There are reports of computers being attacked only seconds after disabling a firewall. With XP service pack 2 there is a built in firewall. However this will only protect you from external traffic entering your PC. What about internal software sending your sensitive data to outside sources without you knowing? You can install third party firewalls which monitor incoming and outgoing traffic to ensure that only permitted data is sent. Enabling firewalls can sometimes cause issues with some services such as remote connections or file and printer sharing etc so make sure you know what you are doing.

Antivirus software

It is common knowledge that all computers should have an Antivirus application installed. When choosing antivirus software consider the following. An antivirus program should have real time protection, automatically update, run frequent scans and not take up too much of your computers resources. Antivirus programs such as McAfee and Norton are notorious for being resource hogs. These may seriously slow down your machine. A computer should only ever have one antivirus program installed.

Antimalware software

Malware is software designed to infiltrate or damage a computer system without the owner’s informed consent. Software is considered malware based on the intent of the creator. It includes computer viruses, worms, Trojan horses, spyware, dishonest adware, and other malicious and unwanted software Common tell-tale signs of malware are: Your homepage has changed, frequent unwanted pop-ups, slow internet connection, slow PC and Internet Explorer crashing. Most users are protected against viruses but are not protected against the full range of malware. Unfortunately there are numerous antimalware programs available for download that are in fact malware themselves. It is advisable to have several antimalware programs installed on your PC. Unfortunately it is next to impossible to keep malware out of your PC so it is important to be vigilant and clean out the unwanted software on a regular occasion. We also advise that you make the switch to the Mozilla Firefox web browser.

Installed programs

Legitimate installed programs can also cause problems for your computer. Viewing your notification area or more importantly task manager it may become evident that you have programs running in the background of the computer that are not needed. Some programs automatically begin when you start your computer so that when you call on them, they will load quickly. However, why should these programs run silently in the background and soak up RAM resources. It is possible to configure the Microsoft Configuration Utility to prevent these applications from automatically running on start up.

Hard disk maintenance

Over time your computer produces many temporary files. These files are the result of such things as Internet use, program installations and Windows updates. These unwanted temporary files can take up a large amount of space on your hard drive. It is a good idea to regularly clear out these temporary files. Over time the operating system places files on different locations on the hard drive as files are created, deleted, modified and saved. While running processes, the computer saves files at random locations on the hard disk. The scattered nature of these files means that you must wait while the computer finds the files. This has an overall slowing effect on the PC. It is important to regularly defragment your drive using a built in or third party defragmenter. This places all the files in a side by side fashion (contiguous files) so that retrieving the files takes less time, It is also important to run chkdsk / scandisk to ensure the disk file system is ok.

The advent of online stock trading software in the late 1990`s – early 2000`s precipitated a surge in stock trading the likes of which had never been seen before. Suddenly, trading in stocks became accessible – and profitable – to almost anyone who tried it.

The days of manually creating charts with ruler and pencil had gone forever; replaced by online technical charting services and analytical tools.

Live stock quotes, once upon a time `only available for a huge monthly fee to the wealthy few` had become a free inclusion on the home pages of countless online stock trading web sites.

The technological innovations within the trading sector rapidly advanced to the point where today, online stock trading software is not only easily affordable – even for the budget-minded trader… but is also equally easy to use.

There`s a vast number of specialist trading software programs on the market, catering for every possible level of experience. Obviously, I can`t cover them all here. However, the following five trading tools from Ashkon Software are classic examples of what to look for in online stock trading software and should all be given serious consideration for inclusion in your trading arsenal.

Number 1 Stock Predictor

Is an advanced stock charting and investment strategy performance analysis software package for technical traders. It allows you to easily display several technical indicators for a single stock on the same chart, maintain predefined lists of stocks and test your own investment strategies. Stock Predictor has more than a dozen embedded technical indicators and over four hundred investment strategies.

Another great feature of Stock predictor that I particularly like is the one-click buy and sell function that gives you a unique opportunity to apply a trading strategy to a given stock and view a cumulative and summarized performance of your investment at any selected point in time.

Finally, I`d like to point out that Stock Predictor has a built-in data feed and no subscription fees. In other words, you`ll never need to pay for your charts again!

Stock Predictor allows you to print and plot technical historical stock charts, apply and construct analog trading strategies, analyze the trading strategies` performances, and give recommendations to buy, avoid, hold or sell.

Stock Ticker Application Bar

This handy little example of online stock trading software has been designed for continuous retrieval of stock quotes through the Internet. It lives at the top or bottom of your computer screen and displays (in real-time) ECN quotes, including pre-market and after hours quotes or `20 minutes delayed quotes` of predefined lists of stocks, indices and currency symbols as a scrolling message.

The Stock Ticker Application bar also displays quotes for up to 200 securities, automatically or manually updates stock prices, has user defined positioning, scrolling speed, fonts selection; includes top and bottom stock price visual and sound alerts.

Another really cool feature of this particular ticker is the stock price percentage change indicator. You can imagine how helpful that is when comparing a given stock`s upward or downward movement with the overall market.

Historical Quotes Downloader

Allows you to instantly download intraday or end-of-day historical quotes of stocks traded in the US. The customized ASCII data output format makes historical quotes data compatible with most technical analysis and charting analysis software packages such as SuperCharts, MetaStock, Advanced Get, Elliott Wave Analyzer, Microsoft Excel, Omega TradeStation and others. No subscription fees.

Stock Sector Monitor

Is a desktop financial application that allows you to easily monitor over 200 stocks and over 7000 public companies online. You can watch daily top losing and gaining stocks from each stock industry sector, see percentage change, quotes, volume and other quotes information, access news, print reports, charts, and create and maintain your stock portfolios.

Ashkon Stock Watch

This is serious charting software for the financial information market. It allows you to display on the same chart several technical single security indicators, open multiple chart documents, test your own investment strategies and maintain predefined lists of securities. While it`s got the usual built-in market indicators such as moving averages, price channels, bollinger bands, volatility, stochastic oscillators and MACD momentum indicators, it`s a really cool piece of software… especially the way it plots technical indicators in multiple panels (I just hate the way some trading software programs try to cram everything inside one small panel – this Stock Watch tool is so refreshingly different!)

Conclusion:

For those of you who are wondering why I chose to review five online stock trading software programs all from the one source, take note: there are over 32,000 web sites in Google alone that focus exclusively on online stock trading software programs. Ashkon is just one of these. However, having personally experienced the quality of Ashkon`s products, I have no hesitation in recommending them. Ultimately though, the onus is on you – the trader – to make the final choice.

Unix inter-process communication (IPC)

Imagine this! You turn on your computer and log into Windows. You are very excited that you finally bought a new computer, and you can’t wait to get online and began surfing the web! So you open up Internet Explorer and your heart is beating fast with anticipation. You’ve now been introduced to fake anti-virus and anti-spyware software!

Fake anti-virus software can be disguised as legitimate anti-virus software, requesting you to download it to protect your system for a “small fee.” Many times people are fooled into buying anti-virus software from non-reputable companies, only to realize later (for example): that they paid $50.00 or more, to download software that doesn’t work; while their credit card is showing additional unauthorized charges from the “anti-virus company!”

The anti-virus company won’t return calls, has no phone number to call and no customer support! As a matter of fact, the company has no real anti-virus software, because they are SCAMMERS!

It’s good to keep in mind that thieves are now using rogue anti-virus programs to steal your personal information and wreck havoc on your financial well being, as well as selling your information to MORE thieves!

Many times, fake virus programs are actually a “Trojan”, which is a program that takes control of your computer while remaining “hidden.” Sometimes, the Trojan creates “false positives,” fooling you into thinking your computer is infected, even though it isn’t. In other cases, this software places malicious code into your computer, causing many unwanted and possibly critical problems for your computer. Beware of clicking on websites or ads that advertise “free virus scanning.” You will usually do your computer more harm, than good.

What to look for to determine if you’re infected

1.) You will see constant alerts that your system is infected, with numerous pop-ups; including system stability issues.

2.) You will get constant pop-ups, even when you are not on the internet

3.) Your computer is dramatically slower

4.) Your desktop changes without your command, or your homepage is changed or is re-directed to another site that you didn’t choose.

How to help prevent fake anti-virus/spyware programs from infecting your PC

1.) Use Firefox instead of Internet Explorer!

2.) Use a good anti-virus program, and make sure it is set to update automatically (new definitions are released daily in many cases as new viruses are released daily!)

3.) Always have a firewall enabled on your computer, even if it is the Windows Firewall

4.) Never open an email unless you are definitely sure that it is from a trusted source (sometimes that trusted source may actually have a virus on his/her PC, sending rogue emails!)

5.) NEVER click on any pop-up that advertises anti-virus/spyware software.

6.) If you get a virus alert on your screen (“You are infected..”) NEVER click it! Instead, press “Ctrl + Alt + Del” to view a list of the programs running. Find the rogue program and click “End Task.”

7.) DO NOT use peer to peer file sharing programs such as “Limewire”, as this is a sure way to get infected; especially if you are not savvy network and computer security.

Hopefully this article has helped save many of you from hours of frustration, and will prevent a trip to your local computer store, or even to TekTime for repair! Remember that it takes effort and education to prevent becoming infected, but an ounce of prevention is worth a pound of cure.

Happy Computing!

Managing a business, practicing your profession and many other things we do in life indeed involves a lot of paperwork and files – from receipts to contracts to many other important documents. With the convenience of the internet these days, business and personal documents are also being kept as files in the hard drive and archived electronically. With this, converting word files to PDF or portable document format has become popular as well.

With the many software and applications that we have today when it come to online files, it is important as well to find a file format that makes our files easy to manage but not easy to alter. PDF files have then become a good choice for businesses and even for personal files that you want to store electronically.

To help you understand the advantages of converting word files to PDF, here are some the good points of using PDF files.

- One good thing about PDF files is that, the software that you will need to open your PDF files is free. All you have to do is download it online and you can already open and read your files without having to spend a huge sum of money.

- Files set in PDF format can be opened anywhere – from your PC, your mobile phone, or your PDA, and that makes it easy and convenient. Of course, the most obvious and main advantage of converting your files to this format is all about portability and being able to access your files anywhere is a good advantage in these times that we prefer services that are fast, convenient and easy.

- Files in portable document format are also convenient because it can be opened in many platforms like Windows, Linux and Mac, thus you don’t have to worry about opening your files in different computers and wherever you want to access your files.

Documents in portable document format can also be signed digitally for authenticity, as this document format also supports good encryption. Of course, this will provide integrity to your documents as well.

- Converting word files to PDF is also a good way to make your files safe, as documents in this format have almost no chance of being infected with a virus.

- One of the conveniences of having your files in the portable document format is that, it also allows compression of your files. Especially if you have lots of graphics in your word file or your Powerpoint file, converting them to the portable document format will help you save memory on your PC and helps you upload your documents faster and easier.

Aside from all these, PDF files can also be created not only from word files but from many other sources. You can create them from scanned images or documents, you can create them from web pages as well as any electronic documents.

The ideal PC Backup Software is one designed keeping simplicity and ease of use as the primary objective. It needs to be very simple to deploy and massively scalable, with backups that are small, non-intrusive, and require minimal end-user interaction.

Deployment of the backup software should require minimal integration with third party solutions. The program should be up and running within 20 minutes.

Scheduling needs to be opportunistic, to ensure that backups are scheduled flexibly at most convenient times. Backups which miss the schedules are automatically resumed when bandwidth becomes available again. Also, small features like deferring the first backup of the day by 10 minutes from the time user logs in, ensure that the user is not disturbed when he starts his work.

But the must-have is always Data De-Duplication (DDD), which give you smaller, faster and almost invisible backups. Advanced hierarchical caching can optimize source-based deduplication for low bandwidth consumption.

If your backup program can throttle the amount of bandwidth and CPU available to the agent for backup, this would ensure that your work never gets disrupted.

Besides these features, the ideal PC backup solution also needs to highly scalable i.e. it should have the ability to support up to 2000+ PCs on a single backup server. It should also enable the administrator to centrally view, guide and control backup users; detailed backup reports and instant alerts would also enhance protection for PCs.

Client-triggered backups are usually the best, always initiating backup and restore requests by the client over a SSL secure channel. This aids in security and scalability of the server. The administrator then just needs only to open a one-way secure port to securely backup remote users over VPN or WAN.

Healing food: natural way to cure cancer

Network Time Protocol (NTP) is a TCP/IP protocol developed when the internet was in its infancy. It was developed by David Mills of the University of Delaware who was trying to synchronise computers across a network with a degree of precision.

NTP is a UNIX based protocol but it has been ported to operate just as effectively on PCs and a version has been included with operating systems since Windows 2000 (including Windows 7, Vista and XP).

NTP, and the daemon (application) that controls it, is not just a method of passing the time around. Any system running the NTP daemon can act as a client by querying the reference time from other servers or it can make its own time available for other devices to use which in effect turns it into a time server itself. It can also act as a peer by collaborating with other peers to find the most stable and accurate time source to use.

One of the most flexible aspects of NTP is its hierarchical nature. NTP divides devices into strata, each stratum level is defined by its proximity to the reference clock (atomic clock). The atomic clock itself is a stratum 0 device, the closest device to it (often a dedicated NTP time server) is a stratum 1 device whilst other devices that connect to that become stratum 2. NTP can maintain accuracy to within 16 stratum levels.

Any network that needs to be synchronised, has to first identify and locate a time source for NTP to distribute. Internet sources of time are available but thee are often taken from stratum 2 devices that operate through the firewall. The only way NTP can peer the time is if the TCP/IP port is left open to allow the traffic through. This could lead to security issues as malicious users can take advantage of this firewall hole.

Dedicated NTP time servers find a source of time via GPS or radio signals and so don’t leave a network vulnerable to attack. By attaching a NTP time server to a router and entire network of hundreds and even thousands of devices can be synchronised thanks to NTP’s hierarchical structure.

Richard N Williams is a technical author and specialist in atomic clocks, telecommunications, NTP and network time synchronisation helping to develop dedicated NTP clocks. Please visit us for more information about an NTP server or other NTP time server solutions.

So why exactly is the Trojan virus infection so dangerous and what can it do to our system if it gets attacked by it? I think that most people reading this article just want a quick solution that can help them remove Trojan virus infections from their computer system but first it’s important to know more about it. A Trojan horse is a type of malware and is arguably more dangerous than a computer virus or worm for the simple reason that it can open up your PC to third parties or hackers across the internet. By granting remote access to other sources around the web the Trojan will enable other people to manipulate system features, delete random files, capture information screens and download more malicious programs onto your system.

So know you are probably wandering how it could have infected your computer system in the first place? Just like any other form of malware, Trojans can attack a system through mail attachments, downloaded software, clicking buttons on web adverts and even from browsing malicious websites which trigger harmful installations. Once it has infected your PC it can enable others to get access from different locations where they can change and harmfully modify existing content or settings. Normally you can determine if you have an infection of this severity on your system because it causes degraded speed, rebooting, internet crashes, inability to run applications, modifications of wallpaper files and you will find that you cannot open task manager.

To remove Trojan virus infections one can follow one of 2 procedures. Firstly you can do what most people do and that is download a security program which can remove Trojan virus infections without hassle. The other more complex method which is only advised for advanced PC users is removal by manual methods. The reason why manual removal is not encouraged is because the Trojan has a complex structure and you will need the correct knowledge in order to remove a specific type which can be difficult to achieve.Furthermore, you should be warned that deleting incorrect files, registry entries or other folders could make your PC even more unusable.

If you think you are infected and need to remove Trojan virus content from your system then I recommend that you scan your system with Xoftspyse which is a powerful anti Trojan security tool. Because it has a definition database of over 100 000 definitions it can easily root out many types of malware and effectively eliminate them from a computer.
