Tips To Choose A Good Notebook Repair Service

When your trusted notebook or laptop stops functioning, it could be terribly frustrating. It could throw your life out of balance depending on how much you had been depending on your notebook. Especially if you are running a business and a lot of business data is stored on your laptop, it might be very important to get your system up and running as soon as possible.

You need to choose a reputed notebook repair service to get your system repaired efficiently. Since notebooks are quite different from desktop PCs, getting them repaired by just about any PC repair company would not do. You need to specifically choose a notebook repair service that specializes in repairing portable computers. Here are a few tips to choose a good notebook repair service to get your system up and running in the shortest possible amount of time.

First of all, look for a company that can handle the whole gamut of faults that can arise in a notebook. The company should be able to handle RAM issues, motherboard problems, overheating problems, hard drive repair and replacement, screen replacement, keyboard replacement, cracked casing replacement and DC Port repair.

Apart from hardware problems, computers can have problems related to software too. Due to virus attacks or malware, the operating system or the data could be corrupted. Therefore, the repair company should be able to handle virus removal, anti-virus installation, saving and backing up of data, recovery and retrieval of deleted or corrupted data, and re-installation of the operating system. Only a reputed repair firm would be proficient in handling all types of hardware problems as well as software problems including data retrieval.

A good company would provide at the very outset, a rough estimate of how long it might take for them to repair your notebook. Companies having highly trained and qualified personnel would often be able to complete the repair job on the very same day. They would then inform you to collect your system from their facility.

Finally, look for a company that provides a warranty on their repairs. It would be meaningless to have your laptop repaired and then have the same problem recur the very next week or month. Ideally, the company should provide at least a 3 month warranty on the repairs they make.

These are a few helpful tips that can help you choose a good notebook repair service in your region. When you follow these suggestions, you would be able to choose a company that can provide you with good and efficient service.

iSCSI Software

iSCSI software is the type of software used in network storage where iSCSI protocol is used. The basic storage network which deploys iSCSI is storage area network (SAN). iSCSI software enables the devices to become connected to the network, share storage space and have access to the data stored on storage servers.

There can be two sets of devices which are in the network. The first are iSCSI initiators - the appliances which send SCSI commands and initiate the contact. The other are iSCSI targets - the devices which receive the commands sent by the iSCSI initiator. Therefore, depending on the status of the device, it will require special iSCSI software - for initiators, for targets or both, since one device can sometimes perform both roles. In the case of iSCSI software for initiators we can have the system initiator. It is a special service running in the operation system. Windows Vista and Windows 2008 are already equipped with iSCSI software for initiator, you only have to select it. In Windows XP and Windows 2003 you can download iSCSI initiator from Microsoft pages and install it. As far as targets are concerned there are also two possibilities.

Many of the modern popular server operating systems can provide iSCSI software with target functionality - either as a built-in application or with supplemental software. They are: BSD, Linux, Solaris or Windows Server. Although Windows Storage Server 2003 R2 is not sold separately, you can buy a hardware on which it is running as the original equipment manufacturer. Such Server are offered by such producers as DELL, HP, IBM or Fujitsu Siemens. An alternative will be a specific-purpose operating system that implement iSCSI target support. The examples of such systems are FreeNAS, Openfiler or FreeSiOS. The example of target iSCSI software offered by third companies is StarWind, which can be installed even on Windows XP and provides all necessary functionality for smaller uses. An interesting solution in StarWind is the virtualization functionality, which can provide access not only to the whole drive, but also emulate the drive by means of a file, whose size can be dynamically expanded.

The storage facilities of the users are consolidated into a data center. A storage system using iSCSI can have many iSCSI targets for a number of clients. Therefore, iSCSI can enable location-independent data storage. The protection of the data and its retrieval is also strongly connected with this type of networking, since iSCSI allows for more efficient data management and disaster recovery by means of storage software.

Look Into the Future of Mobile Apps With NFC

NFC is an extension of the ISO/IEC 14443 proximity-card standard that combines the interface of a smart-card and a reader into a single device. NFC operates in the 13.56MHz frequency band over a distance of up to around 20 centimeters. A NFC tag is a printed circuit integrating an antenna and data from which data can be read or written by a NFC-enabled device. Currently this technology is used primarily with mobile phones.

There are mainly three operating modes for NFC Technology:

a. Read/Write Mode: In this mode the NFC enabled device can read or write data from external NFC tags.

b. Peer to Peer Mode: This mode allows two NFC devices to exchange data with a single tap or by keeping the devices close to each other.

c. Card Emulation Mode: In this mode the NFC device appears to an external reader to be a contactless smart card. This enables contactless payments and ticketing by NFC devices.

NFC communication always involves an initiator and a target. The Initiator device actively generates an RF field and the target device responds by modulating the existing field. There are two modes of communication:

a. Passive Communication Mode: In this mode, the target device may draw its operating power from the initiator-provided RF Field. In this case only the initiator requires batteries. The target can take the form of tags, stickers, key fobs, or cards that do not require batteries.

b. Active Communication Mode: In this Mode, both Initiator and Target device communicate by alternately generating their own RF fields. In this mode, both devices have power supplies.

Key NFC Applications:

The following are the possible applications which can be developed using NFC Technology:

Mobile payment: The device acts as a debit/credit payment card. For the credit card merchants, NFC enabled payments are easier and less costly to handle than cash and other traditional payment methods. In addition, users will have a record of even the smallest payments.

Smart poster: Smart posters promoting new products, services or events will have NFC tags embedded in the poster. By touching an NFC-enabled handset against the tag, the user may be directed to a web site for further information or to book tickets without the need to key anything into the phone to open the browser or input the URL.

Electronic keys: These are replacements for physical car keys, house/office keys, hotel room keys, etc.

By observing the process of conventional mobile commerce and the characteristics of NFC technology, the NFC supported Mobile Application for shopping domain, will generate huge revenue. Shop Mobile Application would be heavily used in shopping domain. Features of the Shop Application can include Bill Payment, Coupon Download, Coupon Sharing, Product Catalogue Download, Product Catalogue Sharing and tracking Shopping Behavior. Some of the security issues that can arise with NFC Technology are transaction forgery, transaction denial and credit card information hacking-need to be addressed.

NFC is the wave of the future. Shop Application will change the entire shopping experience. It will take the customers' user experience to a whole new level.

Working With Creo, The New 3D CAD Software

Creo is a 3D CAD solution made by Parametric Technology Corporation. The software program, which runs on Windows operating systems, combines advanced modeling and drafting techniques plus other tools needed for mechanical engineering in 3D. It was previously known as Pro Engineer and was created by Doctor Samuel Geisberg.

Creo is a good time saver tool for designers. It combines multiple applications like parametric, 3D CAD, CAID and CAM. It produces excellent designs that are up to standards and creative. It also allows data sharing among other applications which improves the speed of data translations, error checking and error corrections.

Creo contains several stand alone applications. These include the 'parametric', which is a standard design application which helps to address challenges in the design. There is 'direct', which helps to simplify and increase the speed of designing or defeaturing and editing.

Thirdly, there is the 'schematic'. It transfers the 2D schematics to the 3D cabling and piping, automatically reducing possible errors. There is a simulation that understands and converts the 3D designs. It translates them into digital images and assists in their testing.

In addition, there is a view Mcad. This application helps to view and visualize the design insights unlike the manual system which involves many people who have to think it through and discuss it. The Ecad on the other hand, makes you visualize PCB types of designs separately or together with the whole product design.

The illustration provides a good environment which is needed for rich 3D technical illustrations whose purpose is communicating major products and actions plainly and graphically. The sketch is a 2D application that assists users to sketch their ideas. They can add other effects to communicate their ideas, like color for example.

Finally there is a layout which is a 2D application that helps to leverage the excellent 2D and 3D worlds in the design process. All these applications are combined in the Creo software. They help improve the speed and accuracy of product designs.

Training on how to use this software can be offered in at certain universities. The training is offered for both, end users and administrators. There are classes held by instructors where people are taught in the lecture halls and there is also a virtual learning library with unlimited access on the web.

There are also questions and answers web pages where users have the possibility to discuss technical issues and get solutions. In addition, there is a community that connects people to professionals. They can write articles on their experiences and get responses from other members of the community group.

Creo is a perfect solution for all designers who need exact 3D models of their drafts. With its up-to-date technology and precision tools you can be sure that the 3D model you create matches all standards that the real world product has to fulfill. The times of prototypes which fail product requirements and security checks are over, with Creo you can get the features you really need, as it can be customized to your requirements.

Why 3D Artists Can Make More Money Than You !

3D developers have the opportunity to see their designs come to reality through 3D printing. When artists print 3D models, they create physical figurines out of their designs. As in, artists can actually hold their designs! How does this work? There are quite a few printing companies that will print 3D models for artists. These businesses will take the 3D model, send it to the printing manufacturing plants, and the plants will create the objects, and ship it! This means, artists don't have anything to worry about after designing their work. They can print 3D models with ease, as companies take care of virtually everything else.

How do these manufacturing plants print 3D models? This technology is known as 3D printing. This process can create virtually anything from a design. The system with these companies works like this. An artist will send a design to a printing company. The printing company will then send the model to a manufacturing plant, and the plant will create the model into a physical product. When the model arrives at the manufacturing facility, the model will be created layer by layer by 3D printers. The companies will deal with everything when it comes time to print 3D models. These printers can use a large variety of materials to choose from. For example - printers can use metals, plastics, ceramics, rubber like materials, mechanically strong materials, and even precious metals. Essentially, these machines will lay down layers of the material, and will fuse these layers together on top of each other. After the manufacturing plant has finished printing, the model will be shipped to the customer. These companies take care of every detail when it comes time to print 3D models, you and your customers don't have to worry about anything! Customers?

Through these 3D printing companies, artists have the opportunity to make a large amount of money, through commission work. One a design is created it is available for anyone to print 3D models out of it. This means that artists can post designs online across these companies, and consumers can buy them to be 3D Printed. Once the design is uploaded, that is it for the designer. Companies will deal with all the work when it comes time to print 3D models. All he or she has to worry about is collecting commission checks per each sale that is made. These companies take care of every other detail. There is no communication with manufacturing facilities, warehousing, or shipping involved. So in a nutshell, artists can make money! They simply upload their designs, and that is it!

This is great for consumers as well; if a company were to print 3D models, the consumer simply has to purchase the item, and wait for it in the mail. No dealing with manufacturing plants, warehousing, and shipping. Another cool thing about this process - 3D model printing is much more concise than other forms of manufacturing. 3D printing can create objects that can't even be competed with by other forms. For example - objects like a ball within a ball can be created. Mechanical functioning 3D Prints can be created in one piece. There are a wide variety of options!

Store More Information With 2D Barcodes

Barcodes have for many years now been the standard way of tagging products for easy identification. RFID has been threatening for some time to take over, but to date has failed to make really significant in-roads and gain mass market appeal. In the meantime, the humble black and white stripes have not rested on their laurels, with new barcode symbologies being developed over the years. One of the most significant developments of recent years has been the continuing rise of 2D barcodes, perhaps most noticeably in the last few months in the form of (quick response) QR codes on adverts.

2D Barcode Fundamentals

What sets 2D barcodes apart is the amount of data they can store compared to a traditional 1D or linear barcode. Linear barcodes generally store a key piece of information about an object - a part number or batch number - with further details such as description, expiry date, etc., only being available once received from a database.

2D barcodes allow far greater amounts of information to be stored within the same area as a linear barcode, or allow the same information to be stored in a much smaller space. Thus, the holding of part number, expiry date and batch number within a small, single barcode becomes perfectly feasible.

2D Symbology Types

Stacked symbologies contain multiple rows of linear bars and spaces - effectively a stack of two or more linear barcodes - for example, PDF417. Stacked barcodes can be read by the majority of laser scanners, laser imagers and area imagers (subject to symbol size).

Matrix symbologies encode data in a grid of dark and light components, with the position of each component relative to the barcode centre being significant. Due to their compact size matrix symbologies are particularly suitable for marking small items. They can, however, only be read by area image scanners.

Application of 2D Barcodes

Whereas a few years ago 2D barcodes were widely regarded as a niche technology, they have more recently become more mainstream. Thanks to their ability as a portable mini-database to hold multiple pieces of information about an object, business processes can benefit from having extensive information immediately available - better stock rotation based on expiry date information, more efficient tracking in the supply chain etc. Small barcode size can reduce packaging volumes, improve first time scan rates and even enable barcode labelling of small, loose and irregularly shaped items. It's no wonder that 2D barcoding is really taking off in manufacturing, pharmaceuticals, healthcare and logistics.

Looking Forward

Whilst 2D barcodes have suffered in the past from the required area imagers being expensive and being unable to scan barcodes at distance, technology inevitably moves on and overcomes any difficulties. With the recent advent of low cost area imagers that can scan at greater distances with acceptable first-time scan rates, it seems it will only be a matter of time before 2D barcodes become dominant (until the next great revolution).

Best Ways to Secure Your Notebook

Your Notebook comprises of your entire personal and professional data and hence, it is more than necessary to protect it from getting in the hands of hackers online or from thieves in the real world. Hence, it is high time to pull up your socks and find solace in a foolproof solution that could protect your most important gadget everywhere and at any cost.

Categorizing security measure

The distinct ways that you adopt can be broadly classified into two categories, i.e.

- Protection of your laptop/notebook from Real theft 
- Protecting it from the hackers that could steal your digital data

Let us discuss them one after another.

Protection of your laptop/notebook from theft

- Use lengthy passwords: This strategy could work actively in your cause. Using strong passwords that contains at least one digit, alphanumeric character and special character apart from the regular alphabets would be considerable. Make sure not to use your date of birth, the name of your family members or friends as the password, it can be decrypted easily.

- Avoid using bags: It is an open invitation for people with negative intensions to carry a laptop bag. It is better if you can replace it with some safer option such as suitcase or padded briefcase.

- Encrypt your data: If unfortunately your notebook gets into the hands of wrong people, file encryption could save you from intensifying the damage further. This is also helpful if you are lending the notebook to someone else for few hours or days. With perfection encryption strategy, those with unscrupulous intentions can not decrypt your data despite of persistent attempts.

- Do not take it to public place: You can forget your notebook while keeping on he floor or on a chair while you are in public place such as a ticket counter or a restaurant. Hence, until it is a very important cause that compels you to take your gadget outside, avoid doing so.

- Use a security device: Attaching your notebook/laptop with a security device such as cable or chain and tying it with a heavy object in the room could prevent your machine from being stolen in your absence.

Protecting your laptop/notebook from hackers online

- Activate firewall: While you are rising your Wi-fi network, turning the firewall is highly recommended. You never know how many fellows are there, waiting for your open your laptop so that they may steal your sensitive data.

- Block unwanted connections: If you are using a hotspot connection then before moving further, make sure to block all the useless connections that appear in your computer. All the operating systems provide efficient ways to perform such a task comfortably.

- For extra safety, use secure website connections: While opening a website, if you use https instead of http, it assures added security to your data. Websites such as Yahoo Mail, and Gmail allow you to use this facility and there are many more as well.

- Unshare folders: Leaving the options of shared folders open could be dangerous if you are using your notebook somewhere other than home. It is not acceptable if someone checks out pictures or video files without your permission, hence it is better to unshared those folders each time you are out.

- Use VPNs: This is perhaps one of the strongest methods to secure your data online. It works on a specialised tunneling mechanism and protects your identity over the internet. Moreover, it also provides you with an IP address of a separate location that keeps you totally anonymous until the time you are online. This not only hides you from prying eyes but also enables you access blocked website.

Toshiba Android Tablet Thrive Certain to Be a Money Maker for Toshiba

When you purchase a tablet, you expect it to function as well (or better) than a laptop or any other piece of on the go technological devices. Toshiba made a run in the Android tablet market and seems to have a very good grip on what consumers want. This becomes most evident when you look at reviews of the Toshiba Android tablet Thrive, which was introduced just in time for the 2011 holiday season.

The Toshiba Android Thrive tablet comes with a 10.1 inch screen, which is exactly the same as some of the best selling tablets on the market today. Even so, it is a little heavier and has a design that is definitely unique to Toshiba. Experts at Toshiba did not want to try and mimic some of the other tablets on the market today, but instead went in their own direction with design and aesthetics. And for Toshiba, this bold design move may be paying off.

The Toshiba Thrive tablet is meant to mimic a laptop more than it is another tablet on the market today. And since it is sturdier and a tad bit heavier, many users find it easier to use. Plus, with features such as USB ports and a removable battery - users are finding that in many instances - especially troubleshooting, it is easier to use than some of the other tablets. Plus, Toshiba put a lot of thought into the design and making it comfortable for users which is why it has a unique and extremely hand pleasing grooved back panel that gives it an easy to grip feel. The back panel of the Thrive is completely removable and users can customize their appearance by using a colored back panel replacement if they so choose.

Since the back panel IS removable, users find that they can utilize two different batteries with this device, which definitely makes keeping it charged much easier in the long run. Battery life is deemed by company specification to be about 7 hours, which is fairly standard for tablets today. Even so, if you are playing games, downloading a lot of watching videos, the battery life is greatly decreased.

This tablet comes with other built in conveniences as well including the following:

USB and HDMI support,
Grooved, textured back for easy holding
Replaceable battery
Inbuilt file management system (Makes it a great choice for businesses)
Easy controls to adjust volume and standard settings
Droid 3.0 operating system
Headphone jacks
Extremely high resolution screen and accurate touch screen enabled.
If you are in the market for an Android tablet that will be able to mimic the heavy duty-ness and function of a laptop, than this is a great tablet for you. It is priced lower than the iPad and has performed better in consumer reports against well known and popular tablets such as the Samsung Galaxy. Plus, made by a company that is as reputable as Toshiba, you know that it has to be good.

How to Build a Desktop

The most important components within a desktop is the motherboard and processor. These components will usually cost more than the others. One thing to be sure of in picking what processor and motherboard your going to use, you must make sure that they are compatible. Both will specify either on the box or on the webpage your purchasing from which processors or motherboards they will be compatible with. The newest generation of processors is would be either the Intel i series (i3, i5, i7), or the AMD Phenom Series II (x2,x3,x4).

The next set of important components would include the hard drive, audio/graphics cards, RAM, and disk drives. These also have compatibility needs, but these are more general than a motherboard and processor. The hard drive and disk drive have many different ways to connect to the motherboard, but the most common is the SATA connection. Make sure if you are using an old motherboard to determine what type of connection it uses in order to connect the hard drive or disk drives. Almost all audio and graphics cards will fit in all motherboards. One thing you must make sure of is that your computer has the proper processing power to handle the extra workload in cases of High definition gaming graphics cards, or high definition audio cards. The easiest way to determine what type of RAM you need to purchase is to read your manual or go online and do some research on your motherboard. You can also look directly at the motherboard above the RAM slots and see it printed on it. DDR, DDR2, DDR3. These are listed from oldest to newest type. Most everyone uses DDR3 now.

The last components you would to obtain would be the power supply, fans, and casing. The casing will depend on what size your motherboard is, but its pretty easy to figure out what size to get (small, medium, large is the best way to look at it). Fans are just for cooling purposes, and they are needed but you don't have to go overboard with fans. Your power supply is very important as well. Everything will be directly or indirectly affected by your power supply seeing as how everything uses power. The best for a beginner with nothing to special inside of their desktop is a 500 watt power supply. Some may say this is too much but I its a safe bet. The individual components, if bought new, will come with a manual that will inform you of how much power it takes.

This is only the beginning of building a desktop. It may seem overwhelming, but as you progress you will realize it is quite simple to get the hang of building a desktop.

Digital Evidence and Legal Proceedings

When it comes to submitting digital evidence for use in a trial, the same levels of care need to be applied as with non-digital evidence.

Crime is a part of human life and, for a crime to be resolved, investigators have to reconstruct the crime scene and analyse the actions of both the suspect and the victim so that any evidence can be identified and used to support and legal proceedings.

As technology has evolved, criminals are now able to use new methods to commit traditional crimes and develop new types of crimes. Crimes committed through the use of technology still require the same principles of investigation, though the scene can now be a virtual environment that must be secured and examined as digital evidence.

Digital evidence is information or data of an evidential value that is stored on or transmitted by a computer or digital device and can be defined as follows:

'Any data stored or transmitted using a computer that support or refute a theory of how an offense occurred or that address critical elements of the offense such as intent or alibi' (Casey, E., Dunne, R. (2004) Digital Evidence and Computer Crime Forensic Science, Computers and the Internet. St. Louis: Academic Press).

A wider array of devices are capable of holding larger amounts of data and digital evidence can be found on an increasing number of types of storage media, including, computer hard drives, mobile phones and removable media such as memory cards.

As an expert witness and Digital Forensic Consultant I am finding that digital evidence is becoming more prevalent within a wider range of both criminal and civil cases including murder, unlawful images, child care cases, commercial and employment disputes. These cases can require the examination of evidence to determine whether it had been used to commit or facilitate a crime as well as to identify supportive material for either side of a legal case.

In order for digital evidence to be admissible in court a number of criteria must be met, including, ensuring that the evidence has not been altered and that an auditable trail has been kept relating to the storage and investigation of the evidential device or media. The key points of the handling and investigation of digital evidence is provided as follows:

Actions taken to secure and collect digital evidence should not affect the integrity of that evidence; 
Persons conducting an examination of digital evidence should be trained for that purpose; 
Activity relating to the seizure, examination, storage, or transfer of digital evidence should be documented, preserved, and available for review.

(U.S. Department of Justice (2004) Forensic Examination of Digital Evidence: A Guide for Law Enforcement, Washington).

The nature of digital devices therefore makes them particularly susceptible to damage or corruption. Due to the constant requirement for devices to be physically smaller in size yet bigger in capacity, the components become ever smaller and more delicate, therefore, even storing the devices in an unsuitable environment can cause the corruption and loss of some or all of the data present.

Therefore, to ensure its integrity, a 'chain of custody' relating to the evidence should be established. This usually amounts to a paper trail detailing the whereabouts of all evidential sources during custody, along with the details of individuals having access to it, when and any actions taken with it. This, along with a comparison and review of the digital media itself should allow for the acceptance by an independent examiner that a given item of media has not been corrupted or compromised following seizure.

As the level of understanding of the operation of computers and mobile phones has developed within legal cases, those investigating cases involving digital evidence have a better awareness of the methods of seizure and handling. Previously it was not uncommon to find cases where the digital evidence had been switched on and operated by a 'curious' investigating officer to 'see what was there'.

Thankfully, far greater emphasis is now placed on audit trails and storing the evidence correctly and, today, such activity by untrained individuals is now rare. The adherence to computer evidence guidelines is crucial to ensuring that the evidence considered is all that was available and basing an examination on flawed evidence that is only partially complete.

As a forensic investigator, I was recently involved in a case that highlights the importance of ensuring the completeness of digital evidence. The case involved an unemployed middle-aged man who lived on his own and kept himself to himself, though, used his computer to talk to other people within chat rooms.

He had been in contact with one of his online friends via a chat room for eight months before they asked for him to do them a favour and cash a cheque that their elderly mother was unable to do. His expenses were to be covered and he saw no problem with then transferring the money to the mother's account. Unfortunately, he did not even think that the cheque could be fraudulent until he found himself in a police station and being interviewed on suspicion of attempting to cash a fraudulent cheque.

He provided police with his version of events; fortunately, they had also seized his home computer. They examined the computer and found evidence to indicate that the defendant had been in contact with the individual, yet found no evidence to support the origins of the cheque or the story behind it. He was subsequently charged with fraud and was due to appear for trial at Crown Court.

Given the partial evidence identified by the police, the defendant's solicitors understood the situation sufficiently to know that a second opinion should be conducted of the computer hard drive to determine whether the evidence of any chat logs could be found on the computer.

It was only after a careful review of the deleted areas of the hard drive, along with the use of data recovery software that chat log activity was identified that supported the defendant's version of events. The log proved that the defendant and his friend had conversed on a number of occasions and it also confirmed the origins of the cheque. After months of investigation, after the identification of this evidence, the case was dropped on the morning of the trial.

Had the computer evidence not been sufficiently protected and secured following seizure and the data present altered in any way, whether it be by use of the hard drive or improper handling of the drive, the relatively small piece of crucial evidence may have been lost and the defendant's version of events could not have been supported.

During the examination process of digital evidence it is standard procedure for the evidence to be connected to a suitable system using write protecting hardware so that no alteration or access to the original device is possible.

Due to the volatility of digital evidence it is best practise to take a forensic 'image' of the hard drive or storage device that consists of an exact byte-by-byte copy of all data and space, both live files and deleted information, which is present on the device. This forensic image then forms the basis of the investigation and analysis and the original exhibit can then be securely stored.

At the start of the forensic copying process, the device is assigned an acquisition hash value (most commonly an MD5 hash value). Once the evidence has been forensically acquired (imaged, similar to copied) the evidence is assigned a verification hash value.

Currently, it is believed that the hash value mechanism indicates that the acquired evidence is a complete and accurate copy of the data contained on the original device and that if the acquisition and verification hash values match then no alteration of the evidence can have taken place.

Various types of hash value exist, including, HAVAL, MD5 and SHA. The forensic arena has adopted the MD5 hash as a method of proving that one file is identical to another or an item of digital evidence has not been altered since its original acquisition. The MD5 hash value was developed from 1991 by Professor Ronald L. Rivest.

As the MD5 algorithm is based on a 128-byte data block, it would appear that there is the possibility that the data on an item of digital media could be manipulated, yet the MD5 hash value not be altered. Given this, I am currently undertaking research to attempt to verify whether an item of digital evidence can be altered without changing its MD5 hash value.

This will enable the adoption of a technique to allow for the alteration of digital evidence without changes to the assigned hash value. The result of this research may be that it is possible to alter an item of digital evidence sufficiently to make the current hashing techniques unreliable in court.

Tips and Suggestions PDF Editor

Portable document files, or PDF files, are meant to be used as replicas of actual documents. They were really not meant to be used for files that have not yet been edited and finalized. It is still preferable to have the original documents corrected and, afterwards, to create a new PDF. However, if the latter is not possible, then, editing of the PDF files may be done as a last resort using the following steps.

If you wish to change some portions of the text, you would need to have specific tools such as Adobe Acrobat & Acrobat Professional, Adobe Illustrator, or Inflx PDF Editor. Take note that PDF file texts are stored as single lines. The text does not flow and create continuous columns as what you see in word-processing applications. In Adobe Acrobat, you can edit minor changes using a tool called TouchUp Text. Any added or deleted text will not move the rest of the text in the column. This sometimes creates problems with the rest of the words in the text. That is why this tool should be used only as a last resort.

Adobe Illustrator has a capability for opening different types of PDF files. However, just like Adobe Acrobat, it can be tricky to use it for altering text. This program does not give you much options on the choice of fonts. It has its own set of automatic fonts, which may not be compatible to the font used on the PDF being modified. It also creates problems on text flow, even on those portions that were not edited.

Inflx PDF Editor provides satisfactory results with regards to editing text and the flow of text on the rest of the document.

You have to be aware, however, that there is an automatic function in PDF that stores a duplicate of the original document. For instance, changing the text of a tagged PDF document will only make changes on the visible document, but not on its hidden duplicate. As a consequence, the original unaltered document can still show up in search engines even after the text has been modified.

If you want to edit images in a PDF file, you can make use of Photoshop and Illustrator with some of the features of Adobe Acrobat. Acrobat gives you options for different types of touchups. You can select the image you want to edit, and which particular object editor you will be using. The edit options appear once you use the touchup object tool to select the image to be edited and you click on it. The image gets re-embedded in the file after you're done with editing the image. You can also use these features for replacing the image with another image. It is advisable that you retain the original resolution of the image you opened. Insert the new image and save it to your PDF.

The Dangers of the Online World

To most people, a computer could not be described as Dangerous. We use them on a daily basis to type letters, perhaps browse the Internet, play games or store holiday photos. However, for some, data contained on a computer or mobile phone can provide enough evidence to form the basis of legal proceedings against them.

As a computer forensic specialist I am currently involved in criminal and civil cases involving an array of different subjects, including corporate data theft and espionage, murder, drugs, fraud, theft, employee misbehaviour, child access applications and even probate. These are not just legal cases either; for example, I regularly receive instructions relating to marriage disputes that involve computers and digital media.

Increased media attention over the past ten years in cases such as those within Operation Ore (relating to 7,000 individuals who allegedly subscribed to websites displaying sexual images of children) and more recently, terrorism and 'happy slapping' incidents, have provoked a greater public interest in proceedings where digital evidence has formed a crucial part of the case.

Not only is there now a greater general awareness of the capabilities of digital evidence and its potential within legal cases, additionally, reports of websites containing indecent images of children are also continually rising each year (The Internet Watch Foundation reports that the number of websites confirmed as containing unlawful material has increased by 62% over the last three years). It would, therefore, appear that the use of this type of evidence is set to continue to rise.

Increasing resources are now being spent on examining data of this type as part of legal cases where previously it was thought unnecessary. In the past it was commonplace for a Police investigator to restrict an investigation to simply identifying 'evidence'. Upon inspection of this investigation by an independent party, as part of a more in-depth review, it was frequent for the evidence as a whole to have been misinterpreted and the case against the Defendant was not as it first appeared.

Over recent years, the majority of criminal cases for which we received instructions have attracted greater attention from the Police. We now frequently encounter cases involving supportive evidence (such as user and/or Internet history) as well as the basic evidence that is relied upon as part of the Prosecution case. However, it seems inevitable that an increase in the number of cases limits what can be achieved within a Police Force's Hi-Tech Crime Unit. Even today we identify the presence of new and previously unconsidered relevant material within approximately 80% of the cases in which we are involved.

For the majority of the time, this is the result of the initial question asked of a Police Hi-Tech Crime Unit investigator, being "What's there?" The question "How did it get there?" is normally asked only when the Defence looks to respond to the initial allegations. Consequently, that question is normally answered until well after the case has been initiated.

Identifying the basic origins of a file is normally relatively straightforward. For instance, the location of the file normally provides the biggest clue; the activity surrounding its creation is another indicator. However, clearly, the presence of a file and even the identification of its origins do not confirm that the accused deliberately caused its creation nor was aware of its presence. To examine that point normally requires far greater levels of investigation, including the piecing together of items of data in order to build a history of that given file and the activity associated with it.

Identifying the basic origins of a file is normally relatively straightforward. For instance, the location of the file normally provides the biggest clue; the activity surrounding its creation is another indicator. However, clearly, the presence of a file and even the identification of its origins do not confirm that the accused deliberately caused its creation nor was aware of its presence. To examine that point normally requires far greater levels of investigation, including the piecing together of items of data in order to build a history of that given file and the activity associated with it.

When dealing with cases involving indecent images of children, for instance, there are various methods for an image to have been created on a computer hard drive, including, but not limited to, websites accessed whilst browsing the Internet, received e-mails and peer-to-peer software, such as KaZaA. Within each of these originating sources several possible mechanisms can cause the creation of a file without the deliberate and intentional actions of the user.

One such example is a case in which I was involved within the last 18 months. This related to a 19-year old male who, like most 19-year olds, lived at home with his parents. However, unusually, this young man faced allegations of making and possessing 9 static and 11 moving indecent images of children. The images had been stored in two folders within his 'user' profile on the family's home computer. After two years of investigation by the Police, that included an examination of the family computer by the Force's Hi-Tech Crime Unit and an externally sourced expert computer consultant as well as a number of interviews and Court appearances, the accused still had not made any admissions of guilt and claimed that he was simply unaware of the presence of the images.

The Prosecution relied upon the fact that the unlawful images were contained within manually created folders of the Defendant's 'user' profile and they also identified the presence of keyword searches for terms that were likely to result in the creation of unlawful material.

I examined the case and noted that the 9 static images had arrived via a small number of web pages containing legitimate adult pornography and had been created automatically by image downloading software. This software, I noted, had searched for and downloaded any images present on any web page that it encountered. A number of further observations were made as to the apparent lack of awareness of the user regarding the presence of the images following their creation.

The 11 moving images had appeared to have originated via the peer-to-peer software named Limewire. The software had been used to download a significant amount of pornography, including these unlawful moving images. Furthermore, a review of the operation of the software confirmed that dubious keyword searches had been conducted and these specific images had been downloaded to a folder that was located within the 'user' profile of the accused.

It was only after a careful review of the system activity that was contained on the hard drive did it transpire that another user of the computer had been frequently accessing the folder containing the target images and had been viewing its contents, including the unlawful images. After 9 months of our involvement and nearly three years of investigation, the case was eventually dropped shortly before the set Trial date.

This case is not an exception. In approximately 20% of the cases in which we are involved we have been responsible for identifying crucial new evidence that has caused the case to be withdrawn. Due to the level of examination required to recognise such evidence, this figure is unlikely to diminish. For the Police, an examination of this detail is irrelevant for the majority of cases. Having previously worked within at a regional Hi-Tech Crime Unit, I noted that while I was there, for approximately 85% of the cases in which evidence was identified, the Defendant would plead prior to Trial. Only a small percentage of cases involved a Trial and even fewer were party to a review by an independent examiner.

Cases involving files encountered and downloaded via websites are also frequent areas of misunderstanding. The presence of a web page or file on a hard drive can be the result of intentional user access, or alternatively, the operation of one of a number of different scripts and software. These scripts can cause the user's Internet browser to be automatically forwarded to web pages containing certain material or cause certain files to be added to the hard drive without the user's knowledge.

As even legitimate websites contain scripts, the majority of computer users will have experienced (and may have found annoyance in having to close them) 'pop-up' windows. These are normally used to forward a user to an advert that often will comprise of a service vaguely relating to the content of the page that was visited (e.g. the autotrader website regularly contains pop-up scripts to websites for car loans or car manufacturers). However, identifying the presence of these types of scripts and software is often difficult. Furthermore, once a suspect item has been found, making the determination as to its nature, ability and activity can be even more complicated.

As digital media increases in capacity it allows users to store more data but also increases the possibility of software or anomalous mechanisms causing the creation and movement of files. This brings with it a corresponding increase in the amount of resources and time required to examine the greater number of processes and, clearly, the amount of data to be examined in order to identify such mechanisms.

Additionally, the increased use in the court room, within both criminal and civil proceedings, of digital evidence brings with it a greater need for the presentation skills required to provide simple explanations of a subject that can not only be difficult to comprehend but also to convey accurately, clearly and without prejudice.

Clearly, the prevalence of digital technology will increase as it becomes even more accessible, usable and capable. This will undoubtedly result in a continuous increase in the number of cases involving and relying on digital evidence as well as increasing the pressure on Police Forces to examine and collate evidence from a larger number of items of digital media.

My concern is that, as nearly happened with the case of the 19-year old highlighted earlier, potentially, the critical facts of such cases will go unnoticed and items of evidence will be missed as a result of the restricted budgets and timescales placed upon a computer examiner. In this regard, the dangers of computers and the online world, for an increasing number of unsuspecting individuals, could be great.

Why Should You Be Nice to Your IT Technician?

If there is one reason as to why you should always be nice to an IT technician in your company, it is that he or she has the capability and capacity to see all that is going on in your computer system if he or she so wishes to do so. To say the truth, there is nothing like privacy when it comes to working on net work or work computers. Even that laptop computer you purchased the other day for your private computing when connected to a company's network, it is no longer private - everything you do on it can be observed by a knowledgeable IT technician.

Apart from this, these professionals can actually check and see any website you visited outside the permitted sites, every email that you sent over the internet, the installed software, in additional to all saved documents in your computer hard disk.

For instance, if a certain investigation mission has been sanctioned by the bosses, there is little the file originator could do to prevent it from being accessed by snoopy IT technicians; in fact, they can access the information even before it has reached its recipients, thereby spilling the beans in advance. However, there are several things you can do to make it harder for unscrupulous IT technicians from carrying out these unauthorized snoops.

Utilize the available encryption technology and encrypt a segment of your computer's hard drive or sensitive files so that if anyone wants to access the said files or any other sensitive data, he or she will have to input an accessing password. However, check your company's IT policies before encrypting the said hard drive as you may have just performed or want to perform a disallowed action. Basically, the information technology policies in a given organization clearly outline how data can be encrypted so that it could be accessed if a password is forgotten by the user. A master password has to be secured, though it should not be availed or accessible to low level IT technicians in a said organization.

Another way of making information in question private is to clearing the browsers' history. Although, this will not prevent higher level IT technicians from accessing and seeing where you browsed while on the internet, it makes it pretty hard for a lower level IT technicians to do so, thereby your private or sensitive data is likely to stay private and where it is supposed to be, or to whom it is supposed to be sent to.

It is quite helpful to be conscious about your email subject lines. When any given IT technician in an organization is carrying out an email troubleshooting task, it is quite common for email subject lines to pop up on his or her system. To try and curb his or her curiosity, try to keep the email subject lines as bland as you could possibly be able to.

Nowadays, it is common for technicians to be bound to confidentiality and ethical agreements, before they could get hired in most organizations. All in all, effective IT department and its staff is normally concerned with ensuring that a said computer systems is working as is expected, in addition to troubleshooting and consequently correcting IT problems as they come and in a quick and efficient manner.

Consider Transportable Tablespace for Quick Movement of Data Subsets in Oracle

The transportable tablespace feature allows you to move or copy a subset of an Oracle database from one Oracle database to another. Transportable tablespace aids in any situations requiring bulk data to be transferred such as during the following scenarios.

- We can use for archival of pertinent data prior to purging it without significant impact to the source database. 
- Migration of the source data from an OLTP to a reporting database of transfer of data from operational data sources to the data warehousing. 
- Transfer of production data to a test platform. 
- We can copy data from the enterprise data warehouse to temporary staging databases for massaging or converting data prior to loading down-stream data marts.

Moving data via transportable tablespace is much faster than conventional upload/load utilities, such as export/import and SQL*Loader. The reason for this is that, transporting a tablespace only requires the data files to be copied across from the source to the target database and integrating metadata pertaining to the tablespace structure. Index data can also be copied or moved without them having to be rebuilt.

When a tablespace is to be transported, it is placed in read only mode to ensure that a consistent image of the data is captured. Then only specific dictionary information is exported from the source data dictionary. Next, the tablespace data files are copied across to the target database via any operating system utilities or commands. Then the metadata describing the tablespace is imported into the target database. This is very fast because the size of the import is minimized. Optionally, the transferred tablespace can then be placed in read write mode. The actual implementation includes using the datapump utility or export/import utilities. The exp utility has a option, transport_tablespace, whereas imp has three options, transport_tablespace, data files, and tts_owners, to support this feature.

You can transport tablespace between Oracle databases that use the same data block size and character set. Also the source and target platform should be compatible and, it possible, from the same hardware vendor. Also, to prevent violation of functional and physical dependencies and referential integrity, another limitation allows only called "self-contained" tablespace to be transported. "Self-contained" means that there should be no references within the tablespace pointing to segments outside the tablespace. For example, if the tablespace set you wish to copy must contain either all or none of the partitions of a partitioned table. The procedure DBMS_TTS.transport_set_check can be used to determine whether or not the tablespace in question is self-contained. All violations reported by this procedure can be seen within transport_set_violations view which will be empty when there are no violations. In order to determine which of the tablespace in the current database have been transported the plugged_in column in "dba_tablespaces" can be checked.

Building Walls Instead of Bridges in Relationships?

In this tech savvy age, we have all sorts of gadgets for staying in touch 24/7. We have smartphones, pagers, Twitter, Facebook, email, etc. You name it and we have it. While contacting a person has become easier than ever, why is it that people are actually lonelier now than when we didn't have any of this fast paced technology to keep in touch?

Maybe being accessible 24/7 is not as fantastic as we thought it would be? Being accessible all the time limits our opportunity to have some peaceful 'down' time. We need that time to maintain some personal freedom and to allow our minds to take a breather, unwind, and just relax.

To gain that much needed freedom, more and more people now avoid answering their phones. Thank you caller ID. We are having a relationship with each other's voicemails instead! People are also interacting more via text, Twitter, or email than actually getting together in person. Are you guilty of this? Aw come on, let's face it, how many times have you avoided seeing a person face to face and emailed or texted them instead?

Technological advancement has actually created a new age way of 'building a wall' between others and us. We simply turn off our gadgets to end communication. The same gadgets that were meant to make communication simpler and faster are the same tools we use to avoid closeness with others.

The need for face-to-face interaction is becoming obsolete and reliance on technology continues to isolate us further from one another. "Getting together" is now done via teleconference calls. We get together with others who share a common interest or common challenge and provide 'support' that sorely lacks within our communities, families, and friendships. Relationships end via text or get posted with a change of status on Facebook!

It is a shame that the more technologically advanced we get, the more isolated and lonely we become as a society. While it's wonderful to be able to connect with someone who lives thousands of miles away, it's sad that those who live within driving or even walking distance from one another opt to communicate via techs than in person.

If you find yourself feeling more isolated than before, put down the phones, walk away from the computer and make plans to get together with friends and family in person. Get to know your neighbors, reach out and form a connection with another. You'll be surprised how many people are craving the same but afraid to step outside their increasingly limited comfort zones.

Everyone Is Getting Or Has the Kindle Fire ?

The "Kindle Fire" is all the rave these days. It seems everywhere we go that everyone has a "Kindle". It is convenient that is for sure, but is it practical? The Laptop is probably better when it comes to computing, but it is not as easy to carry around as the little hand-held device called the "Kindle Fire".

For those who do a lot of writing the Laptop computer is probably far better. The keys are much larger and will fit your fingers much better. Also, you have a larger screen to stare at, then you do with the small hand-held devices. Yes, we prefer the Laptop for most applications.

But for those who are constantly on the go and they need the ability to check messages on the fly, surf the web, play games, read and otherwise occupy themselves while waiting in the airport this little hand-held device called the "Kindle Fire" just may be the ideal way to go.

The "Kindle Fire" is compact enough to carry in your pocket or pulse. You can literally take it anywhere you happen to be going. Not so with your Laptop computer. Sometimes the Laptop computer can be a real burden when you are going someplace and it is hard to fit in your pocket or pulse.

Of course, if you are a person who likes to do a lot of reading you may want to get the "Kindle Fire" and the "Reader" together and save a little money. The great thing about the "Kindle" and "Reader" is they cut down on the suns-glare. It is really annoying when you are trying to read and the sun, if you are not positioned right will cause a glare and actually hurt your eyes. Is this not annoying to you? It is to most of us!

We have found that the price for the "Kindle Fire" and the "Reader" together just may be worth the difference over getting another Laptop computer, especially if you do a lot of traveling. And who does not do a lot of traveling these days?

For just under $200 you can have your very own "Kindle and Reader" when you buy them together as a package deal. Now, no one knows just how long these prices will last, so the sooner we get to the "Kindle Store" and pick yours up the better.

Of course, keep in mind that not everyone needs a "Kindle Fire" or a "Reader", but if you are out and about a lot you may want to consider getting yours for the added convenience that it will fit in your pocket or pulse and carries well that way. After all when was the last time you were able to carry your Laptop in your pocket or pulse?

Just remember this, the "Kindle Fire" is probably the best technology to come along in years and we believe it is the best thing since "white bread." Why not check it out and see if it will work for you? What a world we live in with all the great inventions that have come along within the past few years.

Fingerprint Identification System

Fingerprint identification is considered to be an effective method of identification because no two persons have the same finger prints. This method of identifying individuals has been around for a long time, but the introduction of fingerprint identification software has really made it one of the best identification systems.

The software is widely available these days, so many companies and individuals are implementing it. In an office, it can help in identifying employees, partners and customers in a quick and easy way. In a personal setting, it could be used in a home. The technology is already being used in laptops.


The working of a fingerprint identification system can be divided into two steps. First it scans the fingerprint of the person. This is achieved with the help of a scanning machine that captures the image of the finger. There are a variety of scanners available in the market, such as the Crossmatch Verifier 300 and SecuGen Hamster IV, with different features. For example, the Hamster IV does not need to be promoted for scanning the finger - it automatically activities itself when a finger is placed on the sensor. The second step is the actual print identification. This involves matching of the scanned fingerprint with enrolled prints.

There are two ways of obtaining a biometric identification tool for fingerprints - one can build it on their own with the help of a software development kit (SDK) or purchase an already built system. Of course, the choice depends on available expertise, budget and time.


There are number of qualities that are desirable in the case of fingerprint Identification software. The first and foremost is, of course, accuracy. Software that provide the greatest accuracy, provide the greatest security. Accuracy can be affected by the condition of the finger. For example, scarred fingers are more difficult to scan. Another factor is speed. Identification should be fast, so that it causes as less interruption in work as possible.

Personalization is also a desirable option. When purchasing a fingerprint identification system, one should always check the personalization options. These options enable the user to adapt the software to their needs. The option of a picture along with the name of the identified person is also a good option to have.

Biometric identification is very helpful in maintaining security as it analyzes characteristics that cannot be easily stolen. Fingerprint identification software are a great application of this technology for both personal and business use.

Getting Satisfactory Results in the Manufacturing and Finishing Process

Many people dream of having their own factory to make this widget or that gadget. Some items are dead easy to make an a manufacturing and assembly line can be set up in the garage. These items will tend to be fairly low tech with only a few steps in the process. And example of this would be something like a metal pressing shop where Step 1 would guillotine the metal sheets to the optimal size. Step 2 would punch out the blanks, step 3 would be to press the blanks into the desired shape and step 4 would involve machining the rough edges.

But other items require a far more sophisticated design with various components being created in different streams and being assembled elsewhere. For example take a mobile phone.

There is a production line that is going to make the LCD displays 
Another line would mould the casing (both front and back) 
Another line is setting up the keypad 
Another will be etching the PC card 
Then the PC card must be stuffed with the components and chips and resisters and diodes etc. 
That has to be soldered and tested, 
Then the streams start flowing together where the body has the LCD screen fitted, then that moves along the line where the keyboard is fitted, these two are then connected to the PC board which is then affixed.

After that of course comes the battery and the back and the test before the finished product can be packed and shipped.

At various stages during this process some items will be particularly sensitive to dust. This is true of the etching of the PC boards, the component stuffing and the soldering process. And so to maintain a high quality most manufacturers have these processes within clean rooms

Clean room technology ensures that there is no dust or any fumes or anything else that can contaminate the product. A clean room may be very small just covering a conveyor belt where critical processes take place or can be huge involving whole assembly lines with specially filtered air-conditioning and all staff wearing over shoes, and surgical gowns and masks. Everything depends on the requirements of the process.

Certain food factories have this requirement as do drug manufacturers where sterility in the manufacturing is vital to the end product. So one will often find clean rooms is these places.

The same is true of spray painting. Everyone at some stage or other has bought a can of spray paint to paint something, and usually the results are less than satisfactory. The reason for this is that spray painting and airbrushing requires consistency in distance and coverage and requires and even steady touch. The slightest air current or dust particles floating around and the desired finish is lost.

So professionals always spray in spray booths. This allows them to get a clean and even finish with a coat of consistent thickness. For a truly fin job and item will be sprayed, baked, a flattening sander will take off all the high spots. This process will be repeated and only the third coat, which will be a very light touch provides the final high gloss finish which can only be achieved by professionals in spray booths.

6 Key Factors To Get The Most Leverage From Managed IT Services

Managed services could be merely classified as a component of your company that's outsourced to a 3rd party company to handle the extra workload. Managed IT services possess the most dependable IT solutions to all range of businesses. There is a potential risk tough if you do a chose a wrong one for your business. To avoid unprofessional managed IT services make sure that they fulfill following criterions. 

  1. Abilities:When you outsource your projects towards the organization their own abilities become your abilities. This becomes your obligation to check on the ability of the service-provider and decide whether it is adequate for your business needs.
  2. Services that are offered: Your business may require few services which are not really readily available. Even though IT freelancing services consist of just about all major and minor IT services however merely a well-established organization will be able to provide all kinds of services. Attempt to and figure out whether all of your needs might be satisfied or not.
  3. Flexibility in Business model: The business model ought to be versatile sufficient for the company abilities as well as ease. Select a good IT freelancing organization that provides 3-4 business models to their clients.
  4. Cost Effective Service: Do not blindly believe the IT service provider. Ensure that the cost cited through the organization may be worth the actual services provided them. A few businesses cost just a little greater than typical marketplace prices however their own services will also be over additional normal service-providers. Additionally make sure that you're not sacrificing the quality of service in order to save some extra cash.
  5. Implementation of Technology: Customers ought to carry out up to date necessity evaluation prior to trying to find a business. Discover all of the major and minor technology needed inside your tasks after which complement all of them along with service provider.

Similar to Qmail MTA, Postfix is created by a modular design (similar to Qmail) rather than a monolithic design (such as Sendmail). This make Postfix to have various advantages or strength compared to Sendmail.

Below are some of reasons why some Email administrator prefer Postfix than other MTA system:


Due to Modular Design, Administrator can pick and choose what module to be activated. This feature not only just increase the performance but also tighten the security of Mail Server.


Postfix consumes less system resources than most other MTAs (or at least, with standard configurations). The minimalist design of Postfix Mail Server has make outstanding performance over many MTA.


Postfix provides a better security than Sendmail. You can have a quick search on CERT Advisories and quickly turned up more than a dozen Sendmail incidents. The is because the services of Postfixis NOT executed as root services. This make it is the entire Operating System security more safer and harder to be compromised by hackers.

Hosted Bug Tracking Tools Help Professionals Achieve Design Requirements

Advanced internet usage applications have provided countless web based software opportunities to businesses. An extensive amount of tools are being created under the Software as a Service or SaaS model to provide consumers with a cost effective option over licensed third party products. Online bug tracking is one specific area where these solutions have flourished because the application is simplistic and can be customized to fit individual organizational needs. This distribution model typically involves the hosting of a provider application over the Internet, but can be applied in other venues of business technology over a network. Reduced hardware needs, lower usage costs, and remote access capabilities are a few of the supplied benefits. These products also prevent companies from having to maintain the system or data associated with this type of development tool.

Bug Tracking Tools: What Conveniences Are Delivered By Service Solutions?

SaaS has become a prevalent model for program delivery due to the maturity of web services, new programming approaches, and expanding service-oriented architectures. Increased broadband availability has allowed more businesses to take advantage of services such as hosted bug tracking tools as well. Two specific models are directly associated with SaaS: hosted application management and software on demand. Hosted management involves a provider making a commercial application available over the internet while software on demand delivers network access to a single program copy meant for SaaS distribution. Benefits of this model include:

Simplified Administration
Real Time Updates
Reliable Patch Management
Improved Collaboration Capabilities
Global Access
Reduced Implementation Costs
Enhanced Customization
Minimal Hardware Requirements
Little to No Internal Technology or Data Maintenance
Old-fashioned distribution models require the application to be purchased by the individual consumer or business. The product must be installed on each individual computer, require server hardware for both data maintenance and remote capabilities, and can entail costly support. Applications cannot be customized to fit business needs meaning the users must alter their processes to match the design. Licensing costs often have to be paid each time upgrades are available and the patching process can take days due to individual installations. Updates are performed behind the scenes when hosted bug tracking tools are used, meaning the latest version is available each time a user logs onto the system.

Internally developed solutions are a third alternative; however, they require a vast amount of maintenance and enhancements that take individuals away from important projects. Necessary hardware for implementation can tremendously heighten the cost of an in-house solution. Hosted solutions are priced based upon a subscription fee where the charge is either monthly or annual. It is a flat fee figured by the number of users and features required within the program. The price changes only in circumstances where user counts or feature needs are altered. The initial setup of a hosted program is far lower than that of a local program due to decreased hardware requirements and eliminated licensing fees. SaaS options have made online bug tracking a feasible choice for any sized company requiring a development tool to monitor project oriented or organizational defects.
