SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

Top 5 Tips for Your First Gaming PC

Building a gaming PC could and will be a great experience: from getting the actual parts to getting the fanciest case, everyone wants the best for his beast. These are some tips that will help the newbie to better understand the complex mindset behind the “Pc Master Race”. Let’s break them down in more detail.

Don’t Budget On The Power Supply

You probably already heard this way too many times, but it’s also way too important: budgeting on your power supply will not only be a bad decision, but it could literally destroy your whole system. Many are, in fact, the cases where full 4k ready machines almost exploded due to the fact that they used a D- class imported Chinese power supply. Pay attention to that!

Decide Your Gaming Goals Before Buying

Buying a gaming PC must be a planned and thoughtful decision. First of all, it’s important to clarify to yourself what your goals (and games you want to play) are: for example, it’s pointless to get an ultra-overclocked CPU if you are just planning on playing Minecraft offline. Every configuration should be prepared according to the results you want to achieve.

A Gaming PC For Gaming

When building a gaming PC, it’s important to understand the fact that, if you want to use it for other purposes, it will impact the actual machine’s memory, in particular, if you are planning to use it for graphic design/rendering and such.

Many app developers recently admitted that having a gaming-ready setup (referring, in particular, to the graphics computing power) is not required most of the times, so think about your goals (once again) when you buy its parts! This applies, most of the times, also to mobile app development related professionals.

AMD vs Intel

There you go, the big question. When it comes to processors, Intel and AMD are compared most of the times, since they are literally the only two brands everyone is using. In my personal point of view, AMD processors are a nice fit for entry-level based configurations, while Intel working best in higher specs ones. With AMD’s Ryzen series, this changed a bit, given the fact that these new units are incredibly fast and performing, but I still prefer Intel, overall.

Prices

Let’s break down some prices: currently, if you want to build an entry-level gaming machine you should expect to spend something around 400/500$, while still being able to play almost every game in high detail, these configurations are usually using old generation parts. The mid-level ones are currently fluctuating around 800$, with a potential 2K computing power. The best ones can go from 1200$ to more than 4000$, just think about them if you want to play everything in full 4K with a minimum of 80 FPS.

Marketing E-Commerce Business or Online Boutique on a Dime

One of the biggest challenges small businesses face is using their limited marketing dollars in a way that will bring the best results. Luckily for online businesses like an online baby boutique or web-based jewelry shop, marketing a business online does not cost much when done right. After helping other companies with social media marketing and running my own successful online boutique, I have learned a few online marketing tricks that I want to share with you. In this article you will discover how to get the most out of your marketing dollars as well as how to turn your customers into brand ambassadors.

  1. Focus on SEO. One of the most important marketing decisions you can make is investing into your website's SEO (Search Engine Optimization). However, beware of SEO companies that promise quick results and focus primarily on link building. Before hiring a company, do some SEO work yourself. First, do your research. What search terms do your potential customers use when looking for your products? What search terms do your competitors rank for? Second, work on your onsite SEO. Optimize meta data. Write good quality content that includes search terms you want to rank for, lots and lots of good quality content. Develop internal links between the pages of your website. Optimize images and videos for search engines. Finally, start the groundwork for your offsite SEO by developing relationships with bloggers and social media influencers to earn quality links from reputable websites.
  2. Learn how your customers use social media and the web. To get the most out of your marketing efforts, you need to understand how your potential customers look for your products and where they like to hang out and socialize. For example, if you sell boutique girls clothing, looks for kids fashion forums, parenting Facebook groups and discussion boards for moms. Which social media platform do they use the most? What kind of content do they prefer? Getting answers to these two questions will allow you to deliver content that has the most effect on your potential customers through social media channels that they use the most.
  3. Separate your potential customers into niches and appeal to each niche separately. If your website sells car parts, you can separate your customers into performance, classic or luxury car enthusiasts. An online boutique offering kids clothing, can appeal based on occasion (weddings, birthdays, first communions, etc.) or based on the age of a child (boutique baby clothes, boutique girls clothes , boutique clothes for teens). Each customer niche may have different needs and use social media differently.
  4. Turn your customers into ambassadors. Give your customers an incentive to promote your online boutique. Whether it is through a photo contest, giveaway or an affiliate program card, encouraging your customers to mention your online boutique on their blogs and share your content will ensure exposure to more potential customers at the minimum cost.
  5. Start a blog. Your blog is another great place to feature keyword-reach content, sharable images and videos, build

Does Search Engine Optimization Still Make Sense If Deals Are Usually Closed In Face-to-Face Meeting

If you have a website and have some sort of interaction with people online, you need search engine optimization. Some people still feel that if they are not selling anything on their websites, they do not need to care about their website getting targeted traffic from search engine optimization. They do not know what they are missing out on.

Just to take one example. I have someone who told me that he does not feel that search engine optimization will be beneficial to his company, although he has a website which collect online inquiry from his visitors. After I probed further, he told me that most of the businesses deals that he has closed are mostly through face-to-face meetings. Does it mean that search engine optimization is not important?

We need to look at the bigger picture here. Internet is the most popular medium that people use to look for information and recommendations. If you have read the book "The Long Tail", it states that we are not in an Information Age anymore; we are in a Recommendation Age. People recommend business, websites, products, services on the Internet. I can say that one of the most trustable recommendations on the Internet is probably search engines like Google and Yahoo !, is not it?

Just recall back to the times when you are conducting a search on Google. Do you feel that the information that is displayed on the top 2 pages is more trustworthy? I bet that you will read up the information on the top 2 pages rather than flipping to the 10th page to get what you are looking for.

Now back to the "theory" of search engine optimization is not beneficial or important because businesses are conducted face-to-face. Do you think that if a company's website is ranked well on search engines for its industry, its reputation and call-in rates / enquiries will increase? I have clients who are in the brick-and-mortar businesses getting tons of inquires and calls, just because they are ranked well for their relevant industry keywords. They do not sell anything on their websites too.

This only proves one thing: Effective search engine optimization campaigns can bring you more business, which results in deals being closed on phones, emails, or meet-ups. …

A 1930's Computer

I'll never forget the day that my brother, who runs up his own department in a major software company, came to my house with a box full of computer parts. He told me it was time that I got with the program and join the twenty century. He built this computer right in front of my eyes. I'm using it right now to write this article. It considered of spare parts he picked up from work. It's slow but it works for me. I have worked on-line using this "1930's" computer (his words) for years.

I did not have a clue on how to use this thing. So I made plenty of phone calls to my very patient brother. I was fast becoming a thorn in his side. I'm sure he asked himself more than once 'why in the world did I give him this computer'. But I quickly began to pick up on how to operate my fasinating new "toy".

I had the basics down. It was now time to get connected to the world. When I opened my first dial-up account I was so excited I could hardly contain myself. I was bothering everyone I knew with, 'Are you on-line? You have to check out this site! Hey what's your email address? ' I joined chat rooms and surfed around aimlessly. Then, like a bolt of lightning from cyber space it hit me!

I received a slice of spam in my email. The subject line jumped out at me like a revelation. It simply said, "Work from Home with Your Computer, Earn Big Money!" Something like that anyway. It was some so-called biz-op. Some get rich quick trick. It opened up a whole new world for me. No more hard labor. No more nine to five (it actually was more like nine to nine).

This was my focus now. Money making opportunities. My head was spinning from all the seemingly perfect opportunities out there. I jumped all over the place. From one opp to another. I joined every affiliate and mlm company I could find. I lost a lot of money. I got bruised, burned, and bit! But … I learned a lot and never wave up!

I kept telling myself that if they could do it, so could I. I pressed forward. I got smarter. I looked for opportunities that were right for me. I learned to sift through all the hype and find the programs that I would be able to work. The important thing to note here is that I never wave up. I never quit. I fell flat on my face more times then I would like to remember. But I just got up, brushed myself off and kept going. I did not care what anyone said. I would not give up. I would make it happen.

Shakespeare wrote, "That has not half the power to harm me, as I have to be hurt."

Conrad Hilton said: "Success … seems to be connected with …

Make sure that you have an idea of ​​what direction you are going in before you begin building an application.

It's important to establish early on what the benefit of your app is, what the goal is, what it will look like, how it will flow and why people will take interest in it.

Making An App

The programming that is involved in developing an app for the iPad has been made much more efficient by the SDK, which stands for Software Development Kit.

This can be downloaded for free at the Apple Developer page, and it includes such tools as the Xcode Editor,
Cocos2d and the simulator.

It helps to be a little knowledgeable with Objective C, which is the backbone programming language of all applications on the Apples operating system.

Even if you are not because, you can certainly familiarize yourself with the inner workings of programming an application, and learn how to communicate well with a small team that you put together, and doing so does not have to cost you a fortune either.
