Web applications are so popular that an ordinary user does not always notice the difference between a website and a web application. These programs interact with a mobile browser and therefore are gradually replacing desktop solutions from the niche of education, media, and entertainment. Companies order web applications for businesses, e-commerce, and startups. In this article, we will discuss why you should order a web application from web development companies in Washington DC.
A web application is a program with a two-tier client-server architecture. The client interacts with the user interface (UI/UX) through web browser pages. All data is stored on the server, the exchange takes place over the network using HTTP/HTTPS protocols.
The web application works as a cross-platform program regardless of the operating system in the mobile version (Android or iOS) and desktop (Mac OS, Windows, Linux). Running the program does not load the device, and only a browser on the Internet is needed to work.
The appearance of a web application depends on the distribution of logic between the client and the server. The program is created for specific business tasks. For example, Infoshell is ordered to develop the following types of web services:
- Portal Web App (portals of increased complexity).
Multifunctional project for effective optimization of business processes.
- improve the quality of customer service;
- improve the performance of employees;
- improve communication between departments of the company;
- ensure the mobility of employees;
- make it easier to work with documents;
- give the opportunity to hold PR events of any complexity.
- Custom-designed systems.
CRM is a powerful tool for automating work with customers, effectively solving the problems of control, and planning for business development.
- maintain the integrity of the client base;
- provide sales analytics;
- increase sales;
- optimize the work of staff;
- reduce paperwork.
- ERP system is developed for large enterprises, it opens up new business opportunities.
- standardize reporting forms and information systems;
- improve communication between departments;
- synchronize processes;
- establish integration with partners.
- E-commerce systems (E-commerce, Marketplaces).
E-commerce provides services/products to customers through the web. Clients receive and process orders, and manage the status of applications.
- receive detailed information about the requests of individual consumers;
- promote a new product on the market;
- reduce transaction costs;
- shorten the path of the product to the consumer.
Web apps are dynamically progressing, which allows you to develop custom mobile applications and complex web services. These programs are easy to develop and cost-effective due to these advantages:
- Cross-platform compatibility. There is no need to develop a separate platform. The program is available in a smartphone or computer browser (Safari, Google Chrome, Firefox, Opera), on any operating system.
- Network security. Programs process requests through the secure HTTPS data transfer protocol. The entry point is protected by a centralized configuration. User data is stored on a cloud server, protected from loss even if the hard drive is damaged.
- Do not use client software. It is installed regardless of the characteristics of the hardware. Installation is not expensive, and the update is downloaded automatically on the server. The client interface is updated automatically the next time the page is loaded.
- Reduced costs. There is no requirement to develop a platform for Android and iOS. Functionally, it is not inferior in performance to its desktop counterparts.
- Scalability. A large amount of data is processed by hardware resources without rewriting the code, as well as changing the architecture.
Let’s consider the necessary stages of web application development.
- Creation of UI/UX design.
An intuitive interface of the working model of the program is created without programming steps.
Experts pay attention to:
- screen transitions,
- image graphics,
- branding elements,
- buttons and forms.
Visual elements are created in the design of a web application to include the user registration process, login, search/placement/order of goods, navigation, profile creation, and making payments.
- Backend development.
The key stage of creating the internal part determines the entire operation of the web application. At this stage, a structure invisible to the client is created – a database, a server, and business logic. Developers use the following programming languages for server operations: PHP, Python, Java, and C#. In the internal development of server applications, frameworks are used: Node.js, Laravel, Flask, Ruby on Rails, and others.
During internal development developers perform:
- servicing external interface requests,
- authorization with client authentication at login,
- creating, reading, and updating data.
- Front-end development.
At this stage, developers test the responsiveness and usability of the interface on different types of devices so that the user experience is consistent. The speed of work should not depend on the size or resolution of the screen.
- Software testing.
Experts conduct testing of all important software operations. Most common tests:
- Usability testing of the interface (quantitative + qualitative research). Experts check connectivity, database connectivity, links between pages, and overall user experience.
- Performance check – data transfer rate, rendering, user input processing. The work is checked under heavy load, as well as at different Internet speeds.
- Interface Testing (UI Testing) – the convenience of the user interface is determined, as well as the work of the server with the internal part of the system.
- Compatibility – the product is tested on different browsers and devices.
- Security – check for weaknesses and vulnerabilities.
- Hosting and deploying a web application.
After purchasing a domain and choosing cloud storage, the hosting provider runs a web application on the server for users to access in a browser. Deployment requires:
- source code repository;
- webserver with SSH deployment key setup;
- SSH access to the server.
A web application is a site with interactive elements. They allow users to interact: click buttons, fill out forms, request a price, and make purchases. Email clients, social networks, search engines, online stores, and project management programs are all examples of such applications. If you are thinking about web application development, Inoxoft is a great choice. The company turns web applications into powerful tools to meet customers’ requirements and fulfill end-user expectations.
Optical Gas Imaging – A New and Innovative Imaging Technology
Optical gas imaging (OGI) is a technique that allows for the detection of leaks in sealed containers of pressurized gases. The way OGI works is by using an infrared camera to visualize the heat given off by the escaping gas. Even though OGI technology is primarily used in a professional setting, it can also be used in homes – especially handheld OGI cameras.
This type of imaging can be used to find and fix leaks in a variety of applications, including pipeline monitoring, refinery monitoring, and environmental surveying. In this article, we will elaborate on how OGI cameras work and what are the benefits of owning such equipment, hopefully helping you decide if this technology is right for your needs.
In the vast majority of cases, OGI cameras are used in industrial settings to detect leaks of methane and other gases. Here’s a brief explanation of how they work:
Inside the camera, there is a laser that emits a beam of light. This beam is directed towards the area that needs to be imaged. When the beam hits a gas molecule, it causes the molecule to emit a small amount of light. This light is then detected by a sensitive sensor inside the camera, which is used to create an image.
Unlike traditional cameras, OGI cameras do not require a light source to create an image. This means that they can be used in complete darkness. Moreover, OGI cameras can see through smoky and dusty conditions that would normally obscure a traditional camera’s view.
One of the main benefits of using OGI cameras is that they can detect very small leaks that would otherwise go unnoticed. For example, a traditional camera might not be able to see a methane leak that is only emitting a few molecules of gas per second. However, an OGI camera would be able to detect this leak and allow for it to be fixed before it becomes a larger problem.
Thanks to the benefits they offer, OGI cameras are an essential tool for many industries. However, they can also be very useful as a home improvement tool. For example, if you have a natural gas line in your home, an OGI camera can help you find any leaks that might be present. This is important because natural gas is highly flammable and can be quite dangerous if it leaks into your home.
While some OGI camera models are extremely expensive, they are used by professionals and there is no reason for you to buy one of them. Instead, you can go for a handheld OGI camera, which is much more affordable and will still do the job just fine.
There are many benefits of using OGI cameras, both for individuals and businesses.
Firstly, OGI cameras can save you a lot of money. If you have a business that uses pressurized gases, such as a refinery or a pipeline company, then you know how expensive it can be to repair a gas leak. OGI cameras can help you find these leaks quickly and easily so that you can fix them before they cause too much damage.
OGI cameras can also help you save money on your home improvement projects. As we mentioned before, if you have a natural gas line in your home, an OGI camera can help you find any leaks that might be present – no matter how small they are. This way, you can fix the leaks before they cause any damage to your home.
Another benefit of OGI cameras is that they are very safe. Unlike other leak detection methods, such as using a combustible gas detector, OGI cameras do not emit any harmful radiation. This makes them much safer to use, both for you and for the environment.
Finally, OGI cameras are very easy to use. Even if you’ve never used one before, you’ll be able to quickly learn how to use an OGI camera. This makes them a great choice for businesses and homeowners alike.
In summary, OGI cameras are a great choice for businesses and homeowners who want to save money and be safe. They are very easy to use and can help you find leaks quickly and easily. If you think an OGI camera might be right for you, then be sure to check out the different models that are available. You’re sure to find one that fits your needs perfectly.
Why does your startup need an MVP and what is that?
Any startup starts with an idea, but it’s important to understand that there are a lot of ideas in the world and you have to weed out the unviable ones. If you believe in the necessity of your idea for users — great, but it is logical to check before starting a large-scale work, whether users need it and are they ready to pay for it?
This approach is safer, by checking the demand for your idea, you will save yourself and your company from a wasted effort in developing a product which will bankrupt the company. MVP, on the other hand, is a guarantee that allows you to say with more confidence that your product will be used.
MVP development is the creation of a product which has the minimum required set of features. It allows you to get some initial feedback from your users and decide whether to spend more money on its development. Sometimes it helps to understand that the idea is not interesting to the users and either to refuse development or to reconsider the main idea of the product. You can order the creation of MVP in Purrweb — MVP development company.
MVP can be considered as an alternative or as an addition to the research, which is important to do before you start MVP development. Researching the preferences of your target audience can be very different and is a topic for a separate article.
The purpose of MVP and the research is the same — to get confidence in the necessity of creating a product at the minimum cost, or in the viability of a unique feature if you are developing in an area where there is competition.
It’s important to understand that an MVP doesn’t mean a crude and unfinished prototype of your product. It should be quite the independent and full-fledged product, but it should have the minimal set of the necessary functions, allowing your users to satisfy their need for such a product.
Steps of MVP development:
- Define and articulate the main purpose of the product (or the main advantages over peers; there shouldn’t be many of them) to be realized during MVP development. In fact, the product can have more benefits and features, but in MVP we check only the core of our product.
- Determine how you will measure the effectiveness of the MVP (engagement metrics, numerical metrics, direct user surveys, etc.).
- Develop MVPs for specific capabilities and prepare ways to calculate effectiveness.
- Determine the effectiveness of MVP development, draw conclusions.
These steps may vary slightly for each product, the main thing is to understand the main purpose of the MVP, and in some cases you may need to iterate through several MVPs before you reach your goal and decide what the product should look like.
The conclusions may also vary. I wouldn’t advise you to drop the idea right away; if the MVP results don’t satisfy you, but it may be worth thinking about what to improve and how.
Based on the main purpose of creating an MVP, you can define the benefits:
- Gain confidence in the viability of your idea in a real environment and on real users.
- Saving money and effort by not putting it all into a failed project.
- Identify the most important features of your product that are important to users.
- Get the first real users who will be interested in the product.
With each new iteration, we need to improve the result. That is, the interval from the birth of the idea to its validation, should be reduced. It is clear that everything depends on the complexity of the idea, but the typical tasks and key processes should be minimized in time.
The peculiarity is to put one main value into one prototype. Remember what you need an MVP for? That’s right, to test an idea. One idea/single value. There is no sense in testing several ideas in a prototype at once, so you won’t get reliable data and will only spoil the whole experiment.
You need to test an idea, but how do you do that?
- Create 2-3 single-page (one-page site) where we make your idea of service.
- In the center put the “order” button.
- Determine the test budget for the campaign and the time for measuring the results.
- Set up advertising (context, social networks, or something else) for a pre-selected target audience.
- We start the flow on the webpage.
- See how many people click on the button and draw a conclusion.
If you are satisfied with the results, then take the service and make it nice, beautiful, convenient. If not, then just throw out the idea and move on to the next one. This is just one example of an MVP. To test a new feature on an existing product, you can simply hang a banner or a burning button, measure the clicks, and estimate the general interest of users in the new idea.
In practice, it also happens that while doing hypothesis testing, you might not make a prototype at all. You will find the answer in already existing sources of information.
Below is a list of principles without which your MVP is not an MVP.
- Don’t do it if you can’t do it. Look for ready-made solutions.
- Cut down. Get rid of everything unnecessary in your prototype; leave only the main value for the user.
- No beauty. Don’t delve into design, make a working prototype, and don’t waste resources.
- Know your MVP users. Gather as much information as you can about those who will interact with the MVP.
- MVP is about to see if you can make money from the idea.
- Cut back on MVP development, time, and design. Leave only the main thing that will help test the idea.
- The MVP should work and carry one, core value.
- No backend. To create an MVP, look for options without heavy and long MVP development.
- Get it up and running as early as possible. Even if it fails, we’ll have the advantage of first. If the chip is new, the user will be more loyal.
There’s a checklist for that, too:
- You can be the first users yourself.
- Relatives, friends, acquaintances.
- We write to everyone, visit them, make phone calls.
- Social networks. We ask for feedback from everyone who responds.
- Opinion leaders. Those who are listened to by many people.
- Cold calls.
- The press.
Do not forget about feedback channels; leave your contacts (mail, phones, messengers, and social networks). Information from first users should come to you freely. The man has already spent his time testing your product.
Do not make him look for ways to share his opinion. That’s what we need. Well, about metrics. All the gestures with users, prototypes and so on are used for a purpose. If you have read to this point, you know that this purpose is hypothesis testing. And to test it, you have to actively watch the metrics.
Don’t forget to set up all the necessary counters. Get the data and draw conclusions about where you need to go.
What is MVP development? It is hypothesis testing. It is about speed. It is about the economy of resources. And what is more important, you need to work with it, and you have everything you need.
Space – the greener frontier – is good for business
The European Union Agency for the Space Programme (EUSPA) was established in 2021 to become the operational arm of the European Union’s space ambitions. That means they manage the commercialisation of applications coming from satellites such as mapping, navigation and science missions. We spoke with Rodrigo da Costa, the executive director about the business of space in Europe and its contribution to the EU Green Deal.
What benefits can people expect from European space commerce in the near future?
Space is the new technological revolution, and it is changing the way we live, work and play. From the navigation system in our cars to the landing of the last flight we took, to the map on our mobile phone – even though we may not know it, the benefits of satellite technology are everywhere.
All smartphones sold in the European single market (since March 2022) are using Galileo satnav signals. This improves an emergency call’s location which will result in faster response times and more lives saved.
In other words, space is a solution – an invisible infrastructure providing very visible services.
How is the business of space set to grow?
Annual sales of satnav receivers are forecast to grow from 1.8 billion to 2.5 billion devices from 2021-2031. The consumer, tourism and health markets will dominate. Smartphones and wearables account for 92% of the receivers. Over 10 billion satnav devices will be installed by 2031, globally.
Apart from the consumer market, the professional markets of agriculture, urban development, cultural heritage and infrastructure will also contribute to the revenue stream.
The Internet of Things (IoT) enabled devices and applications, data-driven services and the push for smart cities and mobility will lead to increased demand.
In terms of Earth observation, commercial revenues are set to double from roughly €2.8 billion to over €5.5 billion over the next decade.
What role does knowledge from space play to help protect our planet?
Copernicus Services monitor a number of key climate indicators, such as sea levels, temperature and air currents. This data can then be used to help develop global climate policy decisions.
Through the Copernicus Climate Change Service we provide information about the past, present, and future climate to business and policy makers.
Europe’s space programme provides a wealth of information about climate (see below).
Surveillance of climate
The above image of Norwegian fjords near Tromsø inside the Arctic circle shows the effects of the intense heatwave gripping much of Europe in June 2022. The darker areas of water indicate a massive sediment discharge into the fjords from melting ice.
Copernicus services are used to monitor climate change in environments such as the Arctic regions.
On 30 June 2022, one of the Copernicus Sentinel-3 satellites captured this image, showing the Saharan dust cloud engulfing the skies of North Africa, South Italy and Malta. The storm is expected to persist and reach Spain in the coming days.
There have been several dust storm episodes in 2022 so far. They are bad for human health and also affect solar energy production by depositing sand on the solar panels, limiting their productivity. The Copernicus Atmosphere Monitoring Service (CAMS) provides forecasts to help plan the measures needed to limit the negative effects of dust storms.
EU space applications
Galileo is the European Union’s independent satnav system. Logistics companies use it to track shipping and aircraft use it when taking off and landing. In-car navigation is aided by the fact that Galileo is more accurate over cities than traditional GPS (US) and GLONASS (Russia) satnavs.
Galileo also boasts of better security from hackers. The resilience ensures quality and dependability. Apart from navigation services, Galileo also supports search and rescue beacons for people in distress.
Designed and built in Europe, Galileo is having a massive impact for European and world commerce. Already, the next generation of Galileo satnav is being planned.
The Copernicus Earth Observation programme is used extensively for climate change science.
The Sentinel and other satellites are capable of monitoring temperature and sea level conditions on earth as well as other climate measurements. This data can then be fed into global climate policy decisions.
‘Because the oceans absorb carbon, their temperatures go up, which has a whole host of knock-on effects,’ da Costa said, ‘Including rising sea levels, changes in fish migration, the dying-off of coral reefs and shifts in the world’s climate patterns.’
The EU Space Programme also plays a role in limiting the impact of climate change on the Arctic environment. For example, the accurate navigation offered by Galileo can optimise shipping routes to reduce greenhouse gas emissions and fuel consumption.

The Copernicus Emergency Management Service (EMS) provides information for emergency response to catastrophes, natural or man-made. Whether it’s fires, floods, earthquakes, volcanoes, hurricanes or other disasters, emergency services can make use of the rapid mapping service to obtain highly detailed views of conditions on the ground.
‘Last summer, when wildfires ravaged Greece, public authorities called on the Copernicus EMS to monitor the evolving situation,’ said da Costa. ‘When floods struck Germany, Belgium, the Netherlands, and Luxembourg (also in 2021), satellites provided rescue teams with the highly accurate positioning and navigation they needed to save lives.’
