Web application example for a beginners

The web application example illustrates how UML can be used (and abused!) to specify web
applications, and how complete working applications can be produced from those models. Using the example, a developer can design simple database web applications using the familiar core concepts of UML.

 And, we will also see how going beyond simple examples requires increasing amounts of twisting and redefining of UML semantics, resulting in a language that is hard to use, and no longer “UML” in anything but notation.

Web application example

The web application example breaks the rules of DSM – but in a good cause. Most developers
have seen UML used for specifying databases: classes map to tables and attributes to columns. But what if we could do without behavior altogether? Or to be more precise, if we could specify behavior once for a whole class of applications, and have each application follow that behavior guided by its own data?

Web applications vs desktop apps

We can easily name some famous desktop apps or native apps for desktop computers: Adobe Photoshop, Microsoft Word, Skype, Outlook, TeamViewer, and so on.

1. Security:

Web apps could not outweigh native apps in this regard, and thus they are often not allowed to access local resources. Furthermore, native apps run locally, and they typically interact with device-specific resources, such as cameras, local documents, and so forth. But safety and security are guaranteed.

2. Connectivity:

A stable internet connection is a must when you use web apps. On the contrary, desktop apps can work offline.

3. Platform dependency:

This does not apply to desktop apps. And, web apps are not limited to devices or operating systems. As long as there’s a modern web browser, you can definitely use web apps.

4. Installation and updates:

In order to use desktop apps, we need to download and install them on our computers. Web apps are much more simple to use. Just go to the website address on your browsers (Chrome, Firefox, etc) and you can use their services immediately.

Desktop apps, however, require some manual handling from you. At some point, you will be asked to upgrade the program.

These online apps such as email clients, word processors, spreadsheets, and other programs provide the same functionality as the desktop versions. However, they have an added advantage of working across multiple platforms, having a broader reach, and being easily accessible from anywhere.

The Top 10 Outsourcing Companies in the World

Top outsourcing companies, in some places, used to be a word with a fairly negative connotation. Gripes about lost jobs and the disregard of the local economy were factors that put the term in such an unfavorable position. Furthermore, most notably, top outsourcing companies frees up valuable space and time for companies to focus on core areas of business, rather than tying up considerable company funds in something that can easily and cost-effectively be done somewhere else.

Finally, the complex outsourcing business relationship between partners must have benefits for both sides. There has to be a certain trade off so that both sides see a mutual benefit to doing business together.

6 Ways to Make Money Online from Creative Work

Making money from your creative work might be easier than you realize. Because if there’s one thing the internet values, it’s creative work. Note that not all of these options will be suitable for everyone, and some freelancers won't like uploading their work to some platforms.

From becoming a video game streamer to offering lessons over video calls, here are the six best ways to make money online in 2021. There are over a billion websites online as of 2020, and almost all of them rely on creative professionals in one way or another. From the blogs you love to read to the cat pictures you scroll through, every type of content that makes up the internet is built from creative effort.

1. Sell your work on Etsy

Etsy acts as an intermediary between buyers and sellers; much like eBay, it doesn’t manufacture the products it sells, but like any intermediary, it charges a fee for listing your products. If you’re someone who makes handmade products, Etsy can help you earn a sizable income.

Etsy is an ecommerce platform specialising in creative items. With everything from vintage board games to handmade home decor, the website is an art collector’s dream. The cost of one listing is $0.20 per every four months. There’s also a 5% fee applicable per transaction.

2. Teach courses on Udemy

Udemy and Coursera have been gaining a lot of traction lately. These sites allow creative professionals to offer courses and expert lessons to students of all skill levels, for a small fee. You can create a professionally designed series of lessons for your students to watch whenever they see fit, after they have paid for the course.

Courses are offered over audio and video. And the best part? They don’t even have to be live courses. You can teach anything from web design to languages. 

3. Stream games on Twitch

Are you good at playing video games? That’s right, it’s playing, not making. Another way to earn money is through sponsored brand placements within the videos themselves.

Twitch streamers can earn money in a variety of ways. The first, and most common, is through displaying advertisements under your videos. If you like video games and are good with an audience, you may consider opening up your very own streaming channel on Twitch.

4. Freelance with Upwork

There are plenty of companies that outsource work to talented individuals these days instead of handling them in house or paying an agency to do it for them. If you are a writer, graphic designer, or developer, consider offering up your skills in a freelance capacity.

While a lot of these marketplaces are known for attracting dishonest buyers or offering cheap rates, Upwork has a strong anti-fraud policy for buyers and sellers alike, making it one of the better offerings. They are mostly marketplaces that connect freelancers with those who need their services.

5. Design assets for Envato

Envato also allows you to sell creative services for a fee. By offering a fixed rate on things like designing a logo or creating a website, you can attract buyers who are in need of a more personalised offering. Envato is an online marketplace for digital assets.

From themes and plugins to stock videography, there is nothing that you can’t find on the site. With these licenses, they can use your work for their own online projects, both personal and commercial. The idea is simple. You upload your work and allow people to purchase user licenses to your assets.

6. Sell printables on Redbubble

Redbubble is a marketplace where you can buy custom-printed artwork. From designer T-shirts to printed phone cases, you can find anything there. Once an order has been placed, you get an email on the amount sold and the royalty made.

Since the website is print-on-demand, Redbubble doesn’t require a huge initial investment. You upload your designs to the site and wait for someone to place an order. All of the artwork is created by independent artists, which opens up a lot of avenues for creative professionals.

6 Smart ideas to measure Developer Productivity

Code in and of itself doesn’t make a difference. It is the features that developers make that matter. Today we’re going to share seven creative ideas to measure developer productivity that will help you measure things that have a positive impact on your product and your development practices.

1. Closed Tickets

Counting the number of cards a developer closes over a certain period allows us to see what actual work is getting closed off. Most software projects get managed with a ticketing system that logs the work to be done as individual tickets. Not all tickets are equal, which is why many teams opt to score tickets by effort. Scoring makes it easier to see if someone is working through lots of straightforward cards and leaving the longer, harder tickets to someone else.

Measuring closed tickets is an excellent metric if the tasks are written well and assigned based on business priority. When more tickets get closed, more good things are happening with the project, be that bugs getting closed off or features made.

2. Deploys

Getting work in front of users is the best way to get feedback and to provide value to them. Measuring deploys works well because you’re measuring changes that are getting shared with your users. A deploy is a unit of work that has made it from development to a live web server. Once something has been deployed, it is available for people to use.

You want to encourage your development team to release code often, but you want to make sure that the quality of the code remains high. Like measuring closed tickets, the vast majority of modern platforms will have a smooth and automated way to measure deploys and also to see what work went into a deploy.

3. Documentation Written

Most internal tools like Basecamp or Notion have page counts and attribute pages or parts of pages to the people who edited them. When done well, it can have a lasting positive impact on the rest of the development team, often for a longer time than the developer was there.

Writing documentation is an incredibly under-appreciated skill in development. Documentation can take many forms. Documentation for documentation’s sake can become burdensome, so look out for developers reinventing the wheel by documenting something that they really should have just linked to instead. Measuring documentation written is a bit harder than anything else we’ve talked about, and it depends mainly on how you store your documentation.

4. Stand-up Items Covered

If your team does daily stand-ups, they often follow a standard pattern: what I got done yesterday, what I’m doing today, what is blocking me. This type of measurement shows consistency. If you have a team of people who frequently meet or exceed expectations, you know they’re working well together.

An issue you might face measuring developer productivity this way is it might slow down the standup to ask people to clarify why things didn’t get done, even if there are perfectly reasonable explanations. One of the many reasons why we favor text-based stand-ups is that it reduces the need for one person to be on top of record taking. If stand-ups happen in person, the best way to measure would be for the person leading the stand-up to take notes.

5. Forward Movement

In those cases, you can measure forward movement. Forward movement means the change of a card from the left of a Kanban board, to the right. This type of measurement incentivizes all forms of positive movement. Sometimes tickets get stuck because developers don’t know the complete solution, but they can make positive steps towards finding that solution.

A ticket might go from “Needs Investigation” to “Doing” to “In Quality Assurance”. Each time the ticket moves to the right, that is a positive movement. If the ticket ends up moving backwards, that is a negative movement. Development teams don’t work in a silo and, depending on what other business processes are in play, measuring things like closed tickets might not apply.

6. Code Reviews Completed

Measuring code reviews completed means counting how many code reviews are submitted or reviewed by someone on the team. One of the easiest ways to improve code quality and ensure your developers are learning is to make sure changes are getting reviewed before they get deployed. Be careful though, code review is a time-consuming process and returns little value if the developers in question go through the motions and don’t take the required time to understand the code correctly.

Code review is an essential part of mature software development. Measuring how many reviews get completed indicates how much buy-in code review has within the team, and acts as a proxy for a lot of the other metrics we’ve mentioned.

What makes a Delivery App successful?

If you can even act on one of these tips, then you are going to be much better off with developing your delivery app. This post is going to dig into three aspects of a delivery app that make them successful.

Not only is it tough will technology always advancing, but there are a lot of people trying to gain market share in the delivery app industry. Delivery apps are becoming a huge industry and it seems like it is getting very competitive.

Good User Interface

With a great user interface, it will show your users that you care about their experience and you want them to easily navigate through your app. Like with any app, you need to develop the app with the user in mind. If you are not putting yourself in the shoes of your users, then you are doomed to fail.

A good delivery app has a great user interface that satisfies the user’s needs. This may seem like pretty general app advice, but it is obviously going to help you with developing a delivery app.

Advanced Navigation Features

Obviously, if you are talking about a delivery app, then you are going to need a great navigation feature. Whether you are using the app to deliver something or track a delivery, then you are going to need an amazing navigation and mapping feature.

Features like amazing mapping services will set your app apart from the rest in my opinion, and the proof is out there if you look around.

It is vital that you have great navigation features that make it easy for users to use. If you have a poor mapping and navigation system, then there is almost no way that your delivery app is any good.

Avoid Bugs and Problems

A quick way to destroy the credibility of your delivery app is to have major glitches and bugs. They really do make customers think that you do not care about their experience and that you are just in it for the money.

Outsourcing some of you develop could end up being one of the best investments that you could make. It takes a real expert to develop an app that has virtually no problems. That is even why some people opt to use custom on-demand delivery app experts to help them out.

If you can show customers that you care with a great experience, then you will be set up for success. Nothing is much worse than a lot of problems. Apps are the same exact way, so remember that! If you play a game that is broken with bugs and glitches, then that game will get a terrible review from you.

Front end developers are some of the most in-demand roles, and for good reason—we wouldn’t get to enjoy internet black holes without them. And, we’ll break down all the skills front end developers use and need, but the first is a front end development definition:

Definition of front end developer in 2021:

A front end web developer is the person who implements web designs through coding languages like HTML, CSS, and JavaScript. If you find a front end developer jobs you can see everywhere. In the navigation, layouts including this article page, even the way that a site looks different from your phone (thanks to mobile-first or responsive design).

So, what are skills to you can learn to become a front end developer?

Front end always use primary coding languages to code the website and web app designs created by web designers including to:

1. HTML
2. CSS
3. JavaScript

The code they write runs inside the user’s browser (as opposed to a back end developer, whose code runs on the web server). And, Front end is the one who lays out the streets and makes sure everything is connected properly so people can live their lives.

A front end web developer is also in charge of making sure that there are no errors or bugs on the front end, as well as making sure that the design appears as it’s supposed to across various platforms and browsers.

1. HTML & CSS

HTML is Hyper Text Markup Language and CSS is Cascading Style Sheets are the most basic building blocks of web coding. There are two things, you will you to create a website design. You can’t even add images to a page without HTML.

Based on my experience you’ll have to master coding with HTML and CSS. The good news is that getting a solid working knowledge of either of these can be done in just a few weeks.

2. JavaScript

JavaScript lets you add a ton more functionality to your websites, and you can create a lot of basic web applications using nothing more than HTML, CSS, and JavaScript (JS for short). Moreover, JavaScript is used to create and control things like maps that update in real time, interactive films, and online games.

It’s also the most popular programming language in the world, so regardless of your dev career plans, it’s a super valuable thing to learn.

3. JavaScript Frameworks

JavaScript Frameworks including to: AngularJS, Backbone, Ember, and ReactJS. There are different types of JavaScript frameworks for different needs, though the four mentioned are the most popular in actual job listings.

4. Front End Frameworks

CSS and front end frameworks and they do for JavaScript: they give you a jumping-off point for faster coding. Most front end developer job listings expect you to be familiar with how these frameworks work and how to use them.

5. CSS Preprocessors

With my experience about CSS Preprocessors. Preprocessors are another element that a front end developer can use to speed up CSS coding. It processes your code before you publish it to your website, and turns it into well-formatted and cross-browser friendly CSS. SASS and LESS are the two most in-demand preprocessors, according to real job listings.

6. Responsive and Mobile Design

This means that the site’s layout (and sometimes functionality and content) change based on the screen size and device someone is using. And, responsive and mobile design skills are super important to employers.

Mobile design can include responsive design, but also includes creating separate mobile-specific designs. A bank website with online banking, for example, would benefit from a separate mobile site that lets users view things like the closest bank location and a simplified account view (since mobile screens are smaller).

If front end web development sounds pretty awesome to you, you’re probably wondering where to actually get started. Let's try learn more and more and work, apsolutelly, in the future you will become a master front end developer

5 Important Things Every Drupal Developer Should Know

Drupal is one of the most flexible CMSs in the market right now. It can be configured with thousands of community built modules, which can greatly extend the functionality of a website. So, if you are wondering why we should use Drupal, I will show a important of this.

1. Know your Modules

They’re the building blocks to make a website function. It’s why having a definite set of modules that work well together is very important. And, Modules are very important in Drupal. Nowadays, in a market have a lot of Modules to you can choose 1 for your company.

2. Don’t touch the Core

Drupal like any CMS implementation, so when you install Drupal for the first time, you’re installing a core set of files known as the Drupal core. Moreover, you can imagine Drupal is foundation of a house, the same thing happens when you modify Drupal’s core files.

Furthermore, this can lead to issues when using Drupal’s core administrator capabilities, and can also affect modules that have been installed on the Drupal and app website ideas. In some cases, you need update a Drupal core files to the latest version to fix a vulnerability in Drupal.

3. How to Keep the Hackers Out

Hackers are dangerous of every computer or developer, but to keep Drupal safe and secure, you should know when a security update is available for the Drupal core or modules included on the website, because Drupal is an open source community-driven CMS, it is more likely to be susceptible to exploits.

4. Get Organized

If your Drupal site is customized, you may need to use Drupal’s templating system. Besides, having multiple templates can also be a curse if not organized properly. Organize your templates into separate folders to make them easier to find. E.g., all the node templates that allow you to customize content types will be placed in a “node” folder, field templates will be placed in a field folder, and so on.

5. Learn to Use Drush

Drupal also has a shell interface called Drush that allows you to perform various tasks from the server’s command line. Moreover, It’s a powerful way to automate certain tasks like syncing databases between two servers, and it also allows you to get common tasks done without having to navigate through Drupal’s Admin interface.

There are many other considerations when building out a Drupal website, to me, these as the 5 most important rules to follow. So, you are building out your first website or maintaining an existing website, these considerations can be applied at any stage of the website’s life cycle.
