Keep Your Small Devices Charged Anywhere With A Portable Solar Charger

Portable solar chargers are flexible devices that can make diverse small appliances breathe again even when there is no electricity.

With other energy sources getting costlier day after day, people are considering solar power as the ultimate source of energy. By transferring sunlight into power, people are lighting their houses and also charging different battery-driven devices. Unlike a few years ago, this source of power now can be exhausted without bulky equipment.

Portable solar charger, the pioneering breakthrough, is an amazing device particularly for travelers. Whether you’re backpacking in the European countryside or loosening up on a Caribbean beach, now you can have your portable gadgets charged anywhere. Portable solar chargers are accessible in three most widely used forms:

• Small handheld models that can charge a wide range of cell phones, portable DVD players, GPS devices, iPod and several other portable appliances.

• Fold out model or also popularly known as foldable solar charger that are mainly employed in cars and plugged into cigarette lighters charging their batteries when not in use.

• Torchlight models that avail with secondary modes of charging.

Portable solar chargers often come with indicators that show when the battery is completely charged. If not, the standard charge time can be calculated by the proportion of the amp/hour rating. A number of solar chargers avail with a battery that gets charged by the solar energy when not charging anything else. This allows the users charge their gadgets at night as well. Take note of the minute devices that you employ and how often you require to charge them. After that, pick a charger as per your needs. The prices of transportable chargers differ according to the features they avail with. So, consider your budget while choosing the features.

Not only direct sunlight, some handheld solar chargers can make use of indoors & outdoors lights also. Composed of strong material that comes with reduced heat-transmittance, these gadgets defend the batteries from overheating and insensitive weather conditions. Several chargers avail with the guarantee of not overcharging the gadgets. Secluded with rugged external shell, these chargers are best in durability and retain the juice for a year.

These chargers aren’t just about recharging the batteries but also assisting our dying planet also. Any given day, these chargers are a great alternative as you don’t add to the CO2 in the atmosphere, pollution and even the power bills. While shopping for a portable solar charger, make sure that the store is trustworthy and provides good quality tools.

Effective Ways to Search for (and Retain) Employment

In today’s economy, many people who have worked in lucrative careers are either unemployed or under-employed. However, there are a number of ways that you can enhance your job search to land the position that you really want. And, once you receive the news that you’re hired, you’ll also need to know how to make sure you’re invaluable as an employee.

Before you send your information to employers, make sure that your resume is stellar. Even if your career spans over two or three decades, it’s important to keep your resume as short as possible. Hiring managers need to be able to skim through your resume and see your major accomplishments and qualifications in just a few seconds. Start your resume with a short objective or mission stating, detailing what you hope to accomplish in your new position, and the skills that you’re bringing to the table. Include the dates you worked at each of your most recent positions, and provide references if you have them. This shows supervisors that you’re reliable and consistent, and that other people can vouch for your professionalism.

When you’re called for an interview, dress neatly and professionally, even if the company where you’re interviewing has a business casual dress code. Be sure to greet the hiring manager with a firm handshake, smile warmly and make eye contact when you’re speaking and listening during the interview. Come prepared with a list of questions that you want to ask the interviewer concerning the history of the company, what your daily duties would be, and whether there are opportunities for growth with the company. A day or so after the interview, send a follow-up email thanking the interviewer for his/her time and stating that you look forward to getting a response soon.

Once you’re officially employed, continue learning all you can about the position you’re in. Download free software tutorials and ask questions as often as you need to. Volunteer to help colleagues with projects, and take notes during business meetings. Take it upon yourself to give your boss a weekly progress report, so that you can receive regular feedback on the job you’re doing. And, of course, keep your ear open for the possibility of a promotion. If you’ve been doing your best to contribute to the company’s success, you’ll have the confidence to negotiate a raise when the time comes.

How to measure software quality

In Agile development, companies deploy code fast and often. It gives a company more profits and provides advantages. However, this approach may affect the quality of a product as sometimes companies sacrifice quality due to lack of time.

For many years companies measure software quality. Their goal is to estimate the product for compliance with quality requirements.

It helps release the product at a high-level quality, stand out among competitors and increase company revenue.

However, many companies failed to achieve software testing quality metrics. It happens due to poorly developed metrics that can’t prevent risks.

We will show you how to organize and measure the effectiveness of software testing activities and software testing types.

What is software quality?
Software quality focuses and provides meeting quality standards and requirements. Software quality metrics is a reliable tool to measure how close to established requirements you are or prove a theory. Every project requires metrics that measure a level of quality. But the problem is that company can’t implement all metrics in a project. Instead, they should develop their metrics depend on the project’s goals.

Why software quality measure matter?
Companies that created products according to high-quality standards are more successful than competitors. Implementing and following software quality metrics helps to speed up the development process. It gives insights into how to improve performance and evaluate the following progress.

How to measure software quality?
To create metrics for the project, you should develop quality factors for them. Each metric is associated with quality factors that represent how quantitative it is.

So, companies should create metrics for every quality factor to represent how quantitative it is.

According to Cem Kaner and Walter P. Bond, these metrics must meet validation criteria:

Correlation between metric and quality requirement
Consistency between quality requirement and metric. If quality changes, metric changes too.
If the quality factor changes in real-time, the metric changes equally too.
If we know the value of metrics at the moment, we can predict how to change the quality factor.
To measure software quality, we should compare quantitatively between quality factor and metric.

At this point, a problem emerges: how do we quantify quality factor to compare with its metric.

In software engineering, experts use two types of software quality metrics to solve the problem:

Direct metrics is “a metric that does not depend upon a measure of any other attribute.”
Indirect metrics or derived.
The difference between metrics is that direct metrics depend on one variable. Indirect metrics depend on various variables.

Examples of indirect metrics:

Programmer performance;
A number of bugs are identified during a specific period in one module (defect density). Many companies use defect density as software quality metrics. However, there is one problem associated with it. All failures and bugs aren’t equal and cause by different conditions.
Requirements stability
Total efforts spent on the project, fixing issues, etc.
Another problem consists that some experts name one metric direct when they not. For example, IEEE Standard names Mean time to failure (MTTF) as one of the direct metrics. However, MTTF depends on the various variable as particular time interval, type, and the number of failures.

To develop valuables direct metrics, they should provide:

definite goal (evaluating project status, estimation of reliability of the product)
the particular scope of work (one project, single task, year of the team’s work)
a determined attribute that measured
natural scale for this metric
We can highlight five quality software testing metrics.

Correlation between committed user stories and results that meet quality goals.
Number of failures during STLC. An increasing number of failures during deploys can signal problems in the DevOps process. The metric should reduce with growing team skills and increasing experience.
Test coverage. This metric shows how much of the code is covered by testing. Many experts argue about the efficiency of this metric. However,Google experts insist that the metric can be valuable information for evaluating risks and bottlenecks in a testing activity.
Defect Removal Efficiency (DRE). This metric evaluates the number of bugs after realizing the product and the number of bugs before release. It helps to track the increasing or reducing number of bugs.
Defect retest index. This metric shows how many new bugs are found after fixing bugs.
