Creating a Computer Lab Floor Plan

Setting up a test lab is the best way to test your hardware and software before rolling it out to your end users. Testing everything you plan to deploy ahead of time will save your company and your computer technicians a great deal of time and hassle, but it is important to put some planning into the design of the computer lab.

Computer LabThings Needed

  • Tables
  • Shelves
  • Network connections
  • Computers
  • Monitors
  • Keyboards and mice
  • Network cables

Measure the room you plan to use as your computer lab. It is important to know how much space you will have to work with before you get started. As you examine the room look around to see how many electrical outlets and network connections you have available. The number and location of these power and network connections will help you determine where to place your computers, monitors and other equipment.

Sketch out the design of the room using a tablet or a piece of design software. Sketch out where you want the tables on which the computers will sit. Also sketch out the space for the shelving units and storage cabinets you will need for holding extra computer equipment.

Place the tables around the room according to the location of the network connections and power outlets. In many room designs the power outlets and the network connections will be located around the perimeter of the room. In that case it would be smart to arrange the tables around the edges of the room. Before putting the tables into place be sure to first connect power cords and network cables, then run those cords and cables up over the top of the tables. That will make it a lot easier to connect the PCs and monitors when you are ready to stock the lab.

Place the shelving units in a space where there are no power outlets or network connections. This will help you make more efficient use of space and give you more room to work if you need to add additional computers down the line.

Place the computers you plan to use on the tables, connecting the power cords and network cables as you go. When choosing computers for your test lab it is important to use the same equipment your users do — this will more fully recreate the production environment and allow you to catch any potential problems early.

Wondering What Copper is Worth Now

I got to thinking about this after something happened to this guy that I work with. He went out of the country on vacation and he was gone for over a week. When he got home he turned the lights on, but nothing happened. He realized pretty soon that there was no sound coming from his refrigerator. It took him a little while to realize that someone had crawled under his house and stolen the copper wire. I wonder how much is copper per pound, because my understanding was that the price of the stuff had gone down a good deal. Of course the cost of scrap metal is related to the global economic activity. If people are building a lot of autos and a lot of homes, then the price is going to rise. Conversely if people are not doing stuff like that, then the price of metals like aluminum and copper will go down. Continue reading →

Practical Measurements For Software Testing

Every software development company focuses on developing quality software. The only way to track the software quality is evaluating it at every stage of its development. It requires some kind of metrics, which is obtained through effective testing methods. Each stage of software testing is effectively monitored for the software QA.

1. Software measurements are used for:

2. Deriving basis for estimates

3. Tracking project progress

4. Determining (relative) complexity

5. Understanding the stage of desired quality

6. Analyzing defects

7. Validating best practices experimentally

Here, some software testing metrics are proposed for black box testing that has real world applications. It discusses:

Importance of software testing measurement

Different techniques/processes for measuring software testing

Metrics for analyzing testing

Methods for measuring/computing the metrics

Advantages of implementing these metrics

These metrics helps in understanding the inadequacies in different software QA stages and finding better correcting practices.

What is measurement and why it is required?

The process of assigning numbers or symbols to attributes of real world entities for describing them according to defined rules is called measurement.

For developing quality software, several characteristics like requirements, time and effort, infrastructural cost, requirement testability, system faults, and improvements for more productive resources should be measured.

Measuring software testing is required:

1. If the available test cases cover all the system’s aspects

2. For tracking problems

3. For quantifying testing

Choose the suitable metrics:

Several metrics can measure software-testing process.

Here, the following types of metrics are identified:

Base metrics:

These raw data are collected in a testing effort and applied in formulae used to derive Calculated Metrics.

The Test Metrics comprise of the Number of

Test Cases Passed, Failed, Under Investigation, Blocked, Re-executed and Test Execution Time.

Calculated metrics:

They convert the Base Metrics data into useful information. Every test efforts must implement the following Calculated Metrics:

% Complete

% Defects Corrected

% Test Coverage

% Rework

% Test Cases Passed & Blocked

% Test Effectiveness & Efficiency

% 1st Run Failures

% Failures

Defect Discovery Rate

Defect Removal Cost

Measurements for Software Testing

The corresponding software testing process in software development measures each step for ensuring quality product delivery.

1. Software Size:

The amount of functionality of an application determines this and is calculated by

Function Point Analysis

Task Complexity Estimation Methodology

2. Requirements review:

Before software development, the Software requirement specifications (SRS) from the client are obtained. It must be:











The Review Efficiency is a metric that offers insight on the review quality and testing.

Review efficiency=100*Total number of defects found by reviews/Total number of project defects

3. Effectiveness of testing requirements:

It is measured by maintaining Requirement Trace-ability matrix and specification of requirements, which should have:

SRS Objective, purpose


Functional Capabilities

Performance Levels

Data Structures/Elements Safety




Constraints & limitations

Next comes the updating of the crucial requirement trace-ability matrix or RTM, which determines the number and types of tests.

While measuring the mapping of test cases, the number and priority of requirement it tests, its execution effort and requirement coverage must be determined.

The Requirement compliance factor (RCF) measures the coverage provided by the test cases to one or set of requirement(s).




j is a set of requirements and (j=1-m);

Xi=2, if the test case (say Tj) tests requirements Ri completely,

=1, if it tests partially,

=0, if otherwise.
Effectiveness=RCFj/Ej where Ej=Time required for executing a test case

4. Evaluating estimation accuracy

Relative error=(A-E)/A where E is estimate of a value and A is actual value.

For a collection of estimates, the mean RE for n projects is

__ n

For a set of n projects, the mean magnitude of RE (MRE) is

___ n

Of a set of n projects, an acceptable level for MRE is less than 0.25.

If K is the number of projects whose mean magnitude of relative error is less than or equal to q,
then the prediction quality pred(q)=K/n

5. Measurement of Efficiency in testing process

In software testing, we must keep tabs on what we had planned and what we have actually achieved for measuring efficiency. Here, the following attributes play major roles: –

Cost: The Cost Variance (CV) factor measures the risk associated with cost.

CV=100*(AC PC)/PC, AC=Actual Cost, PC=Planned/Budgeted Cost.

Effort: Effort Variance (EV) measures effort.

EV=100*(AE PE)/PE
(AE=Actual Effort, PE=Planned Effort)

Schedule: Schedule Variance (SV) is important for project scheduling.

SV=100*(AD-PD)/PD where AD=Actual duration and PD=Planned duration.

Cost of quality: It indicates the total effort expended on prevention, appraisal and rework/failure activities versus all project activities.

Prevention Effort=Effort expended on planning, training and defect prevention.
Appraisal Effort=Effort expended on quality control activities.

Failure effort=Effort expended on rework, idle time etc.

COQ=100*(PE + AE + FE)/Total project effort.

Product –

Size variance: It is the degree of variation between estimated and actual sizes.
Size Variance=100*(Actual Software SizeInitial Estimated Software Size)/Initial Estimated Software Size

Defect density: It is the total number of defects in software with respect to its size.

Defect density=Total number of defects detected/software size

Mean Time Between Failures: MTBF is the mean time between two critical system failures or breakdowns.

MTBF=Total time of software system operation/Number of critical software system failures.

Defects: Defects are measured through:

Defect distribution: It indicates the distribution of total project defects.
Defect Distribution=100*Total number of defects attributed to the specific phase/Total number of defects.

Defect removal effectiveness: Adding the number of defects removed during the phase to the number of defects found later approximates this.

Benefits of implementing metrics in software testing:

Improves project planning.

Understanding the desired quality achieved.

Helps in improving the processes followed.

Analyzing the associated risks.

Improving defect removal efficiency.

Stave Off Business Problems Before They Become Critical With Accounting Software

All medium and large companies hold regular meetings at which the financial accounts are presented and discussed. While all businesses have problems from time to time rarely do medium and larger businesses actually go out of business and if they do it is invariably because financial mistakes have been made.

Small business should take note of this fact and especially self employed business that often do not have regular presentations of the financial statements and the ensuing discussion. Considering the financial state of a business is a critical area that is so often missed from the management of a small business.

Every business has to prepare a set of financial accounts. Those financial accounts may be produced manually or using financial accounting software. The main objective of producing the accounts is all too often to satisfy taxation requirements and not the financial control and management of the business.

When accounts are prepared on an annual basis the day to day financial management of the business is reduced to the size of the bank balance. When that bank balance reaches a critical low level the small business will react but the action required to fix the problem may well have been endemic for many months. Early action is always best.

By using accounting software and the financial control it can offer the small business not only provides an early warning system but also indicates where management action is required. Financial accounts should be prepared by all small business on a monthly basis to maintain financial control.

Accounting software can be a simple system of producing a monthly profit and loss account and for many small businesses that may be sufficient as the smaller the business the more intimate knowledge the owner has of its finances. Other types of accounting software can produce balance sheets and with a balance sheet the value of creditors, debtors, bank balances and assets. In larger organisations the financial accounts will be more sophisticated and produce analysis of all main areas of the business.

During the financial life of a business there are types when sales grow and times when sales decline. The amount owed by customers is called debtors and the debtor balance may grow in line with sales turnover but can also move according to the efficiency of the financial control and credit control systems in place. The movement in the debtor balance potentially having a critical financial effect on the liquidity of the business.

The overall movement of the debtor balance on a day to day basis is not always obvious and only by producing a specific total at the end of each month can the debtor balance be viewed and questions asked to maintain strong financial control. Slippage in credit control procedures must be tackled at the earliest stage to avoid a serious financial impact on the business.

Purchase expenditure can also increase and reduce and the creditor balances can increase and decline. There is a tendency in businesses not making sufficient profit for the creditor balance to grow as the time taken to pay suppliers is extended. Such action may be necessary and is a natural reaction but the real cause should be addressed, that cause being an inadequate level of profitability.

The profit and loss account for a small business should not be viewed as an administrative headache but a vital tool in the financial management and control of the business. A monthly profit and loss account produced by accounting software should be viewed more of a financial health check on the business.

The profit and loss account will show the sales turnover and a list of purchase expenses producing a net profit or loss for the month. By comparing the current month to recent previous months the trend of financial performance becomes obvious. This is a critical function of accounting software to produce real numbers that will indicate where action is required.

The accounting software retains previous financial information entered that enables sales to be monitored and the effect of sales and marketing campaigns to be seen in real numbers. Purchase expenses and business costs can also be viewed and patterns can be easily detected. Any numbers produced by the accounting software can then provide the basis for management action to either improve financial control or take management decisions to grow higher sales or reduce costs.

By using a financial accounting system to critically review the business finances on a regular basis provides both opportunities for sales growth and higher profit levels but also serves as an early warning system of business problems. A profit and loss account and in larger businesses a balance sheet too are essential tools in achieving financial control of the business and producing the desired financial performance.

The absence of a suitable accounting software system or used purely for tax purposes once a year leaves the financial performance of the business to the intuition of the management and is unmeasured. Imagine if the same criteria were used in a sporting context.

A long jumper practises every day and believes he is jumping well but never measures his jumps or analyses his physical condition, training schedule, run up speed. It would come as no surprise if another long jumper with similar ability who monitored fitness levels, worked on the run up and jumping technique and measured every jump would in competition jump the farthest.

And so it is with accounting software and regular financial control. If the numbers are produced on a regular monthly basis the numbers can be diligently analysed and an improved financial performance will follow but most importantly business problems can be detected and fixed before they become terminal.

Custom Software Development Company: A Vital Business Tool

In this every business has different types of requirements. Now a day many types of online business are available in market. They include online services, e-commerce business, m-commerce business etc. And for that particular business, different types of company, firm and organization have different types of requirement for software development.

Software companies are developing software for feeding the increasing demands of companies which are using software for their internal & external operations. Software development is now become the need for any businesses. Today there are many companies who are running businesses online and for them keeping their software’s updated with the latest technologies are mandatory for customer satisfaction and to gain a competitive edge.

With the talented pool of software developers, analysts, lead programmers, and project managers, these software development companies are offering the best business critical software solutions in a time and cost effective manner.

Why You Should Use Computers To Teach Critical Reading Skills

A major concern of secondary school teachers and college instructors is that students are not learning those critical reading skills needed to progress satisfactorily through the upper levels of their education. The primary issue concern is that students who do not learn these skills well in the lower grades will be unable to properly process the academic information they are presented with in the future. Commercial reading software developers have worked hard to create software that gives learners real opportunities to read critically and develop critical reading, and critical thinking, skills.

Computer Software is Interactive

One of the primary benefits of commercial reading software is its ability to engage the student. Most current reading software requires that a student do more than merely punch buttons. Most programs strive to develop real two-way communication with the student, allowing the student to become involved in the learning process. Interactive software provides students with the opportunity to generate their own questions and leads the student through guided practice situations. Newer software has even developed ways for students to interact with each other via the internet. Students work jointly in virtual groups to expand their individual learning experiences.

Computer Software Uses Scientifically-Backed Research to Educate

The reality is that educational software that purports to teach without the backing of sound research and statistics often fails to hit the mark when it comes to really educating children. For this reason, it is important to use software based on established teaching strategies as well as credible research studies. Computer software also facilitates learners filling in gaps in prior knowledge with supplementary video, PowerPoint, and other interactive presentations. Many in-class software programs also include an online component enabling students to access and explore additional information which they can share with learners across the world.

Computer Software Creates a “Real” Learning Environment

Until the advent of desktop computers, reading experiences were limited to print materials. Early programs were only used as supplements to a general reading lesson, rather than acting as a stand-alone reading experience. These factors meant that early computer reading programs were unable to satisfy the needs of children learning to read critically. Modern reading software can be used in conjunction with traditional reading programs, in lieu of such programs, or as supplements to them. This flexibility indicates that reading software has come a long way in providing real reading experiences which mimic those of print materials, yet yield readily to formatting changes. The ability of the new generation of reading software also lends itself easily to a collaborative social environment which studies indicate helps learners construct meaning from reading materials.

Reading software developers are working vigorously to keep up with the demand for increasingly sophisticated reading opportunities. As the world becomes more digital, the next generation of readers accesses more information online than ever before using their personal computers and devices such as their mobile phones, X-boxes, Ipods and Kindles. Formulating reading programs that incorporate this trend will help ensure that technology keeps up with student preferences and will provide new readers with sophisticated, interactive reading lessons that stimulate the imagination and increase learner knowledge.

The Evolution Of Source Code Analysis

Automated source code analysis (SCA) technology is designed to locate and describe areas of weakness in software source code. Those weaknesses may be security vulnerabilities, logic errors, implementation defects, concurrency violations, rare boundary conditions, or any number of other types of problem-causing code. Source code analysis is distinct from more traditional dynamic analysis techniques, such as unit or penetration tests, since the work is performed at build time using only the source code of the program or module in question. The results reported are therefore generated from a complete view of every possible execution path, rather than some aspect of a necessarily limited observed runtime behavior.

The underlying technology associated with SCA is called Static Analysis and the current generation of technology solutions is capable of providing sophisticated, high-value analysis that will identify critical bugs and security vulnerabilities in code that can potentially cause system crashes, hacker exploits or affect the overall reliability of mission-critical software. As a result of recent innovations in this domain, organizations that develop mission-critical software are adopting SCA technology as a standard milestone of their integration build during pre-quality assurance (QA) activities. This has proven to be a useful stage at which to perform static analysis and has provided benefit in terms of accuracy and comprehension. However, build-time analysis suffers from an inherent weakness: code has already been committed to a source branch, so by the time a bug is discovered it is already impacting other members of the development organization and other elements of the system.

Professional software development organizations are now looking to better integrate static analysis technology into their software development processes and to implement this capability as early as possible in the software development process rather than strictly as a build milestone activity. Reduced costs, better QA efficiency, and significantly improved software products are all benefits to organizations that are able to move high-quality source code analysis and software quality tool to the earliest point in the coding phase: the developer’s desktop.

This paper examines the evolution of source code analysis from developer desktop to integration/build and beyond, and describes how Klocwork Insight uses revolutionary new technology to be the first to take the next step in that evolution.

First Generation Source Code Analysis: A Developer’s Tool
The technology behind source code analysis � static analysis � c static analysis – has been around almost as long as modern software development practices. Fundamentally, the technology is a derivative of the compilation process, and for almost 30 years tools such as lint have been available to developers to run against their code.

Second Generation Source Code Analysis: The Comeback Kid
Realizing the limits of the first generation of source code analysis technology, a new generation of tools emerged in the early 2000s. These tools extended the analysis beyond syntactical and semantic analyses to include sophisticated inter-procedural control- and data-flow analysis and new approaches for pruning false paths, estimating the values that variables will assume, and simulating potential runtime behavior.

Third Generation Source Code Analysis: Klocwork Insight
Klocwork Insight is the first source code analysis product that allows developers to take control of the analysis process while also benefiting from the accuracy and value of centralized analysis – with none of the downstream auditing that second-generation techniques required.

About Klocwork Klocwork is an enterprise software company providing automated source code analysis products that automate security vulnerability and quality risk assessment, remediation and measurement for C, C++ and Java software. More than 200 organizations have integrated Klocwork’s automated source code analysis tools into their development process, thereby:

�Reducing risk by assuring their code is free of mission-critical flaws
�Reducing cost by catching issues early in the development cycle
�Freeing developers to focus on what they do best – innovate

Webinar Software

Webinar SoftwareSometimes you may have a great topic to discuss, ideas to share and the best of software but you webinar may still fall flat. It’s difficult to predict one particular reason for it, as there can be many reasons behind a failed webinar. Over the past few years professionals who regularly attended and conducted webinars have reported that those with catchy titles not only saw a vast number of attendees but also were also more likely to be successful. And why not, don’t we read e-mails with catchy titles? Don’t we pick up books that have a catchy title at the book store?

Here are few ways on how to make catchy and powerful titles for your webinars

  • Start with an action verb

The best way to attract attention through the title is to use a call to action. In order to trigger the desire of the reader make sure the title begins with an action verb. For example- a title like “Tricks to host a successful webinar” will generate more attention.

  • Start with “how to”

This is the most widely used format for searching on the internet and also the best to get desired results. Start the title of your free webinar with “how to” since the basic aim of most webinars is to teach people something.

  • Include searchable keywords

In the internet world one thing that works are keywords. In your title make use of keywords that are more likely to be searched by people. Using the right keyword can attract the attention of major search engines, thereby making more people notice your event.

  • Keep it short

Nobody likes to read long and complex sentences. The trick is to deliver most information using minimum words. Be clear about your topic and let it reflect in the title of your webinars. A really long title is difficult to remember and can easily make people lose interest.

  • Use odd numbers

Start your title with an odd number. Something like, ” 7 tricks to host a successful webinar” if you are planning to present only 7 tricks. Odd numbers are more appealing than even numbers and it is also necessary to keep these digits below 10. There’s no specific explanation as to why odd numbers work but you can increase the size of your audience by using numbers like 3, 5 and 7 in the title of your webinars.
