I get asked all of the time about how to make money as a freelance computer programmer. The last few years I have been doing some freelance computer programming, so I guess that qualifies me to answer the question. So far I have refused to go with those services that stand between you and your money, such as freelancer.com, Fiverr, Upwork, and Guru.com. It has been working out for me just running ads in certain publications and using a contact form on my website. Although it has been fine, I know it could be better. I thought about running some kind of email campaign but I don't really want to run a spam operation. I guess it would be alright to buy a list where the customers have already opted in. I have also thought about pay-per-click, but now days PPC is very expensive for any search terms that would drive decent, qualified traffic to my website. Guest blogging to generate links may also be an option. I'm not sure. I think I'll try all of those methods for generating freelance computer programming work one of these days, but for now I'll just leave this article here and maybe one day someone will read it and give me a call. Seriously, feel free to call me about your project anytime.
Every skilled workman is a master of the best tools of his trade. The same is true for great organization. They make use of the best tools for delivering their products and services and are master of those tools. They also staff the best people to use those tools. When you want to purchase their products or services, you can be sure that they have put in topnotch efforts into it.
At expertcoders.net, we’re no different. As a matter of fact we’re even better and ahead of the pack. We make use of some of the best technologies for delivering the products and services we offer. When it comes to the development of any kind of software – whether it’s a desktop app, web app, mobile or any other kind of app you can think of – we employ the best technologies for building that software.
In this article we will highlight some of the technologies we use here at expertcoders.net for creating the software applications we make. Please note that we have used the terms tools, technologies and libraries interchangeably in some places.
It must be emphasized here that the list that follows does not cover all of the technologies we use. It only covers some. This is because in the software development industry, there are so many technologies for creating different applications or even functions of the applications. Sometimes you will have to employ different technologies for creating just one app. The following lists simply touches on some of the main or major technologies we use. There is much to be said about each of these technologies but we will limit how much we say about them to how they’re useful to you.
So, over to the technologies:
Python: Python is our top-line language of choice. (In the course of this article you will come across one or two more languages for carrying out specific development function.) Python is a general or all purpose cross-platform programming language. It is one of the most popular and versatile programming language. It is used across a wide variety of industries. One area where it’s best used is in the AI or Artificial Intelligence fields. Python’s design pattern emphasizes code readability.
While we will not go into all the details about Python in this article (you can read about it in this article on python on this website [link to article]), it is important to note that the fact we use Python as our major programming language is beneficial to all of our clients. And some reasons for this include the fact that because of Python’s general purpose and cross-platform nature and widespread use across several industries, we can develop applications across all field and those applications will run on multiple platforms and Operating Systems. So whatever your field or the operating system you are aiming at, you are covered.
Also, Python readability simply means that its code can be maintained by anyone proficient in the language. It is unlike some other programming languages whose codes are not that readable and as a result sometimes confuse even the programmer who wrote them. (This sometimes is not a very big problem, thanks to code commenting, but it does pose problems in some cases). Since we follow best practices you can have you code maintained by any proficient programmer.
It must be noted, however, that the best person to manage or maintain your applications are those who created it. Nevertheless, someone else can do same.
Enough said of Python!
For web applications we make use of several technologies as this field is one that has many technologies designed for doing many tasks. But some of those technologies are as follow:
For web frameworks, we make use Django, flask, pyramid and several others. The reason for this is that each of these web frameworks is best suited for some specific purposes.
Django for example is posed as a web framework that perfectionists who need to meet a deadline use. It’s about the best choice for creating websites that are content oriented among other uses. Instagram, Dropbox and YouTube are prominent examples of sites made with Django.
Flask is known to be a “microframework” for Python and is best suited for building or creating smaller applications, web services and APIs.
So depending on your needs, we have the best web frameworks for it.
When creating any server side application, you must make use of databases. There are many databases for building great applications but we make use of some of the best as most just overlap in function. We make use of MySQL, PostGreSQL, Oracle, MongoDB and others. During development, we make use of Sqlite 3. This is a free lightweight database best suited for development purpose.
So much of the work people do are done on desktops or mobile devices. Developing for these devices is a must and we stand out in this area. For both mobile and desktop software development we make use of a number of technologies including but not limited to Qt framework and Kivy. These are great for building any application for both desktops and mobile screens.
Qt (pronounced as ‘cute’) is an open source toolkit used in the creation of cross-platform applications that run on multiple software and hardware. These could be embedded systems or Android, Mac OS, Linux or Windows. It is also used in designing GUIs (or Graphical User Interfaces). It is usually classified among native widget tools as the majority of GUIs/applications developed with it have a native looking interface.
Kivy: This is another open source, cross-platform technology for non web apps development. Its basic focus and strength is in building mobile and multi touch apps software that have an NUI or Natural User Interface. These apps can run on Windows, OS X, Linux, iOS and Android.
Testing and debugging is an essential phase and component of the development cycle. This is one phase that makes a big difference between a great app and a problematic app. Never contract a developer that doesn’t test and debug their codes or applications.
For testing we make use of a number of great technologies but topmost on the list is Selenium. It’s our default technology for testing web applications. Tests written in Selenese (the domain specific language provided by Selenium) can be written in any of the popular programming languages. These include Scala, Ruby, Python, PHP, and C#. With this tool we write functional tests that can be run against the majority of web browsers.
Version control is important to us at expertcoders.net so we employ a number of version control technologies including Git, Mercurial and Veracity to name a few. These technologies are open-source, robust, flexible and fast. Veracity has Agile Software Development and Bug Tracking tools included in it.
With these tools, all changes to your application are noted and stored and should there be a need for some kind of revision, you can be sure you will not be disappointed.
Web Scraping is an important topic for businesses as it plays an important role in marketing, competitor monitoring and others. For web scraping we make use of several technologies that depend on the particular data type you want scraped but the most used of those technologies is Beautiful Soup.
Beautiful Soup: This is the most sophisticated and advanced library for web scraping and is designed in Python. It is used for parsing content from within the HTML container of websites that do not offer any APIs.
Apps and software intended for scientific and technical computing are not left out. We employ a wide range of technologies and libraries in this area including SciPy, NumPy, MatplotLib, and Pandas etc. These all come under the SciPy project umbrella and are open source libraries for engineering, science and math.
For use with Modbus in enabling communications between a network of several connected computers we employ some of the best Python libraries which include uModBus, Modbus-tk, MinimalModbus, and PyModbus.
We have not detailed all or any of the technologies we employ in creating great software applications for you. The list of libraries, tools and technologies we use is rather vast. We have only mentioned a few and said very little of the few mentioned. The whole idea here is just to assure you that whatever you need in an application, we have and are masters of the technologies that are needed to build them.
Web applications or web apps are everywhere and in much use today. They have become an integral part of our everyday life. Several years back and it was a different story as they were not made use of as much as they are today. We can say that “they have come a long way.” In this article we will look at what web apps are and why you need them. If you are wondering what they are, be rest assured you have made use of several. You may only be ignorant that that’s what they are called.
A web app (short for ‘web application’) can be described as any computer program that performs tasks over the internet by utilizing web technologies and web browsers as clients. Another way of saying it is that a web application is a client-server computer program where the client runs inside a browser – this includes client-side logic and user interface.
The word ‘client’ is used to refer to whatever program a person uses to run the application in a client-server environment. A client-server environment can be described simply as one in which multiple computers share or transfer data. The data shared can be as simple as the names of your lovely children entered into a database. In this analogy, the client is the application that is used to enter the names of the children while the server is the application that is used in storing those names.
A web app can be as simple as a job application form on a website or as complex as a gaming app meant for several players or an online banking app.
What this means is that if you have used any email service online (e.g. Gmail, Yahoo, Hotmail etc), filled any form, taken a survey, ordered a product on an e-commerce website, or even played a game on a website, you have used a web app.
There are other types of applications you may have used as well. These include mobile apps and desktop apps. Desktop apps are applications that run solely on your PCs and laptops. Mobile apps on the other hand run on your mobile devices.
A web app can be configured with an interface accessible to mobile devices. This is called responsive design. When you view a responsive website on a mobile it looks and feels as though it was configured for a mobile device – like a mobile app. The main difference between a web app and a mobile app lies in the fact that a web app runs in a web browser, is accessible to all devices and has no issues or concerns with OS or device compatibility while a mobile device on the other hand has all of those issues and concerns.
In this section we’ll talk about the reasons and benefits of a web app.
There are several reasons why you must develop and use web application if you are offering anything (product, service, counsel etc) to people that can be accessed over the internet. The most important of these reasons is that a web app can be accessed by all a sundry so long they have access to the internet. And by everyone, we mean irrespective of the Operating System and type and brand of computer or even mobile device being used. One person may be using a Mac, another a PC and they’ll both have access to your web app. In terms of Operating Systems, someone may be using a Windows 10, another a Windows XP, another a Linux or Ubuntu and yet another an OS X and they’ll be able to access and interact with your web app. The same applies for mobile devices.
Closely related to accessibility is that web apps eradicate the need to develop for different Operating Systems and machines. If you decide to not use a web app, you will have to develop an application for all the different types of Operating Systems out there whether on Laptops or mobile devices. This is because the people you want to reach do not all use the same Operating Systems or machines. Some use a Mac running OS X, others a PC with Windows 10 and so on.
Another important reason you need a web app is the cost of developing one versus the cost f developing an application for all computers and Operating Systems. No doubt developing for all computers and operating systems will cost more. Besides the actual development work, you’d have to pay to host separately in many cases.
But with a web app, all of this can be eliminated and the cost of development drastically reduced. All you need is one app and everyone is covered. Why? Web apps are commonly developed using a using a combination of both server side technologies and programming languages like Python, PHP, Asp, Java etc and client-side technologies and languages like Html. The long and short of this is that web apps are designed to be accessible by your browser so long you have an internet connection. And aside from a few web applications designed for specific browsers, most applications can be accessed by any browser.
- The cost for both the user and business is reduced as there is reduced maintenance and support. As a result it is easy to have a large number of people using your app due to the reduced cost of maintenance and support.
- Limitation of space is eliminated on the user end as they are not installed on any hard drives the user owns.
- Since all users have to access the web app over the internet, they all access and use the same version at all times. There’s nothing like I haven’t been able to upgrade due to so-and-so reasons. Once any changes are made to the web app, everyone accesses it. This also does away with any and all forms of compatibility issues.
Some examples of web apps include online storage services like Dropbox and Google Drive, email programs like the ones mentioned above, shopping carts and ecommerce websites, Microsoft 365, Google apps such as Google Slides, Google Sheets, Google Docs and many more. Social media applications like Facebook, Instagram, and LinkedIn. Online note apps like Evernote and a host of other everyday applications that cover areas like file sharing, video and photo editing, word processing and sharing of Calendars and documents online to name a few.
The fact is: A web application can be designed for virtually anything you can think about. So no matter your line of work or business, there either is a web app for it or one can be built and customized for you. And when we at Expert Coders handle your project, we give you the best. We have all the technologies, expertise and years of experience needed and can build any type of web app you need. Best part is we leverage best technologies that make it easy for any web app we build to scale easily.
While it is true that you can develop an application specifically for every device and Operating System your target users make use of, it is always of great advantage to develop and use a web app. This is because there are many issues or concerns associated the former such as high development cost, device and Operating System compatibility and more. Web apps on, the other hand, run within browsers and can be accessed by everyone and a single development or maintenance effort covers all users. This eliminates compatibility issues and high development costs. On the side of the user, it greatly reduces the costs associated with maintenance and support.
We are convinced you do not have any doubts as to whether you need a web app for your business or services – no matter your field of endeavor. You do not need to go about searching for developers for your web app. As stated above, you can get any kind of web app built for you here at expertcoders.com. We are proficient at all levels or phases of the development cycle and in the technologies necessary for building you a great web app. We also have a great support team waiting to attend to you.
From time to time you will need a way to measure and manipulate several real world conditions around you. While you may not, as a person, have control over these conditions, you will need a way to manipulate or control these conditions to your liking. For example, you personally do not have the power to make a hot room cold but with the use of certain systems like an air conditioning unit (or system) you can change the temperature of the room to something more suitable for you.
Sometimes you may need to ensure that a certain condition remains at a specific measure because at that measure of the condition, certain other things are supposed to happen. For this you will need a way to measure the condition and know if it’s above, below or on the specific measurement. In these and many more occasions you will need a data acquisition system. You may even be sampling the same or a range of conditions over a wide geography for research purposes. At times like these you need to be able to acquire data for your research purposes.
Data acquisition is a process in which conditions in the real world are sampled in the form of signals which are then converted into digital values for manipulation on a computer.
A simple explanation of this would be that a data acquisition system is brought in to measure the temperature of your room. The real world condition being sampled here is a measure of the degree of hotness or coldness. The data acquisition system (normally abbreviated as DAQ or DAS) measures the degree of hotness or coldness in the room and converts the resulting temperature into an analog value which the system further converts to a digital value you can monitor, control and manipulate on your computer’s screen.
A data acquisition system is a collection of software and hardware that allows one to measure or control physical properties or characteristics of something in the real world. It is an information system that gathers, stores, and sends out or distributes data or information. They are made use of in commercial and industrial electronics, and also scientific and environmental equipment designed to be used in capturing electrical signals and/or environmental conditions on a PC or any other computer.
A DAQ system that is complete includes data acquisition hardware,
a computer in which is running a data acquisition software, signal conditioning
hardware and actuators and sensors. A data acquisition System that is a
stand-alone is called a data logger.
In some cases, the DAQ system, together with the hardware components, may come with a specialized Data Acquisition Software. In some other cases, the DAQ system may come without this software. In this case you will then need to buy one or have one custom made for you. Even when the Data Acquisition System comes with specialized software, you may still need to customize it for you specific needs. The software is essential because the Data Acquisition applications are managed and controlled by a software program. This program may be developed using any of the several all purpose programming languages which include but are not limited to Lisp, Pascal, Python, Java, LabVIEW, C#, C++, C, FORTRAN, BASIC, Assembly and many more.
No matter what the specific use of your data acquisition system is, you can have a custom-made software built for you here at expertcoders.net.
One important real life application of Data Acquisition systems is in configuring of smart homes or smart offices or smart anything (you fill in the blank). In a smart home, for example, one may want that anytime he claps his hands, the lights will go off or come on. A DAQ system is employed to recognize or measure this sound. The DAQ process then takes place and triggers a reaction that ends in the lights going off or coming on.
- Data Acquisition Hardware: Interfacing between the signal and a PC is the job of the data acquisition hardware. The data acquisition hardware generally takes several forms and could be one or more of these forms: It could be in the form of cards which one connects to the card slots in the motherboard of a computer (examples include PCI, PCI-E, MCA, ISA, AppleBus, S-100 bus etc) or in the form of a modules which the user connects to the ports on a computer (examples USB, serial, parallel etc). In many cases an external breakout box will be required. This is because the space on the PCI’s back is usually too small to accommodate all the necessary connections to be made.
- Sensors: The sensors are responsible for converting the physical properties or parameters into electronic signals.
- A Circuitry for Conditioning Signals: known as the signal conditioning circuitry, this circuitry is responsible for converting the signals from the sensors into a type of signal that can, in turn, be transformed into digital values or values that are readable by the DAQ software.
- Analog-to-Digital converters: the work of the analog-to-digital converters is the conversion of the conditioned sensor signals to digitized or digital value.
Besides the main components listed above, a data acquisition system may also be equipped with any number of several other devices for customized or specialized functions. These tools or equipment may include Remote Terminal Units (or RTUs), Temperature Recorders, Data Recorders/Loggers, and Data acquisition cards.
Besides managing and controlling the DAQ applications as stated above, the Data acquisition software is essentially required for a PC to work with the DAQ hardware. The device drivers expose a standard API that is used for developing applications while at the same time performing low –level reads and writes on the hardware. An example of a standard API that is used is COMEDI. This API acts as a user interface for the DAQ Processor, while also letting a particular user application run on several operating systems and providing graphing and disk logging capabilities. With an API such as COMEDI, a user application that runs on Linux operating system will also run on a Windows operating system.
The Data Acquisition Process – How It Works
The summary of the data acquisition process is this: a physical or electrical property or characteristics is captured. This property is then converted into data which is then inputted into a computer. Some examples of the kinds of properties or characteristics include light intensity, temperature, force, gas pressure, flow of fluids, sound, current, and voltage.
The basic procedure that all data acquisition systems follow is the same, irrespective of the physical or electronic property being converted by the system. And it is as follows:
1. First, there are sensors and these sensors have to gather the target data.
2. When the sensors are through gathering the data, they then output the data onto a signal conditioning circuitry. It is this circuitry that is responsible for converting the data into an analog input.
3. When the conversion into analog input is complete, the analog signal data is then converted by analog-to-digital converters into a singular digital form.
4. After the completion of the last step – the conversion of the analog signal into singular data form – it is then inputted into the data acquisition software. Once inputted into the DAQ software, the data can then be controlled by and is also accessible by the DAQ software programs which make use of any of the all-purpose programming languages. Examples of these languages as stated above include Java, Python, LabVIEW, C++, C, C#, BASIC, FORTRAN, Lisp, and Pascal.
There are so many instances for which you will need data acquisition systems installed. (A look at the types of real-world conditions to be measured as stated above will tell you this.) You may or may not be using them in your line of work currently. If you do, you already know the importance of DAQ systems. If you do not currently use them in your line of work, you may want to find out what these systems can do for you in an age where data is gold. Sure, not all lines of work require a sophisticated data acquisition system but if yours does, get one immediately. It can save you a lot.
Some of these data acquisition systems come with a specialized data acquisition software with which you can access, read or control values on a computer but some don’t. When they do not come with a Data Acquisition Software or you need a custom data acquisition software built for you, remember that we at expertcoders.net have all the necessary expertise, experience and technical know-how to build a great DAQ software for you.
Very often there arises the need for you to gather very large amounts of information for several purposes including marketing. For most businesses, gathering large amounts of data is actually an integral part of the marketing process. If you are to do this yourself or employ humans to do it, it will cost you so much and take so much time to accomplish. In this article we will look at one of the best ways for doing this at a fraction of both the cost and time. This method is known as web scraping. We at ExpertCoders.com can also help you with everything you need for successful web scraping.
Also known as screen scraping, web harvesting or web data extraction, web scraping refers to the automated processes carried out by a software (bot or web crawler) to scrape (copy or extract) data from a website. These software access the World Wide Web through an intermediary such as a browser or directly using the Hypertext Transfer Protocol. The data gathered and copied is saved to a file on a local machine (computer), or to a database or spreadsheet.
There are several reasons why you may want to scrape a website but they can all be summarized in one – you need to make use of the data. The data on websites are usually viewed through browsers but saving them automatically when needed is a functionality not offered by browsers.
To build any form of web page, a text-based mark-up language (XHTML or HTML) is used and these pages can often contain very essential or useful data which can be exploited for your needs. The majority of these pages are, however, designed to be readable to human end users in preference to automated use. This instantly leaves the option of the user manually copying the data himself. The problem with manually scraping data from the web is that it is a slow and very tedious process which makes automating the process a favorite.
Since manually copying data on websites is a tedious process it is natural to rely on software that can automate the process and accomplish is in a fraction of the time it will take a human to do it.
So back to our reasons for scraping the web: Some reasons for or uses of web scraping will include in monitoring and comparing prices online, data and web mining, monitoring of weather data, research, detecting changes in a website, integrating data into a website, monitoring your competitors by tracking and scraping product reviews, gathering of prospects contacts for a business, as a part of applications employed in web indexing, gathering listings for real estate, web mashup, and for tracking online reputation and presence.
A typical example of an occasion where web scraping will come into play would be that you need the names and Urls of certain companies you may intend to market a product to. But since getting them manually may be too hectic as there may be thousands of them, scraping the web for this information would be the best option. Another example is that you want the names and contact of people in a specific niche – people who have provided their bio details on other websites in the specific niche or one related to it.
As stated above it is possible to manually copy data you need from a web page. And although this is possible, copying out the information or data needed from websites manually is a very tedious process. This leaves you with the option of automating the process. To automate the process you will have to make use of a web scraper.
A web scraper can be describes as an Application Programming Interface (API) that is used in extracting data from a web page or website. Better still, you can say it’s a software with an API that allows you extract data from a web page. There have been several forms of web scraping but more recent forms involve data feeds from web servers to be ‘listened’ to.
Some websites, however, employ certain methods in preventing web scraping. These methods of prevention include the detection and disallowing of bots or web crawlers from crawling their web pages. Many web scraping systems, in response to this, apply techniques that rely on computer vision, DOM parsing, and natural language processing as a way of simulating human browsing so as to gather the content of web pages for offline parsing.
To scrape a web page, you need to get or download the page and then get the information from it. For you to view a web page with a browser, the browser, basically, has to download the page. This makes crawling the web an essential part of web scraping as web pages have to be fetched for use at a time different from when they were gotten. When the pages of the website in question have been fetched, extraction can then begin taking place. The web page’s content can be searched, parsed or even reformatted with the extracted data saved into spreadsheets on a local computer or into databases in a server.
While there are many web scraping software available in the market, there is no ‘one size fits all’ that you can rely upon for any need you want. This is because data structure differs from website to website. The best software solutions are those that are built specifically for scraping the website you want scraped. This is why you need ExpertCoders to build a web scraper for you. The web scraper we design will match the data structure of the websites you want to harvest. And if you need one that recognizes different data structures, we will have that built for you too.
There are several techniques employed in web scraping. These range from fully automated techniques to ad-hoc or human copying of the data needed but each technique has its limitations. Some of them include:
- Human copy and paste: As the name indicates, this involves someone manually copying and pasting the needed data from the target web page or website.
- Text pattern matching: This involves using the regular expression matching abilities of certain programming languages like Python, Perl etc to match and extract the target data. This approach is very simple and it is equally as powerful.
- Http programming: This involves the use of socket programming to retrieve both dynamic and static web pages from a remote web server by posting Http request to the server.
- Html parsing: This technique exploits the fact that many websites display or put data within templates. Different data types are categorized and put within separate templates. Web pages that display similar data types are encoded with similar templates. It is this structure that is exploited in Html parsing.
Other techniques used in web scraping include Computer vision web-page analysis, Semantic annotation recognizing, Vertical aggregation, and DOM parsing.
With the introduction of Beautiful Soup in 2004, harvesting the web got even easier. Before this time scraping websites was limited to websites that offered APIs to access their public data. But with Beautiful Soup, the most sophisticated and advanced library, designed for Python, parsing content from within the HTML container of websites that do not offer any APIs became possible. Thus, some of the best web scrapers are written in Python and Python is our programming language of choice here at ExpertCoders.com
You can get a web scraper built for you here at ExpertCoder.com. The web scrapers we build will always be tailored to meet your needs. Even if you need one that is configured for multiple websites, we are still the developers you need as we will build one that is custom made for the websites you will be picking. Other generic web scrapers are built for just about any website and so are mostly inefficient. Since you will be specifying to us the data types you want to extract before we build, the one we build for you will have the ability to effectively harvest that data. We will also build a web scraper that is user friendly and intuitive.
Irrespective of the business you run, to stand out or even lead the competition, you will have need of data for different purposes as specified above. This data would have to be extracted from different sources or web pages available on the internet. Doing this manually will prove to be a cost intensive effort. This is where a web scraper comes in. But since there are different data types and a generic web scraper will be inefficient for scraping every data type or web page, a custom made web scraper is the best option for your business or even personal use.
The answer to that question is usually made obvious when you consider several individual aspects of the Python programming language. And that’s exactly what we’re going to do. We will examine several aspects of Python that make it the best programming language for you to use. And even if you’re a client wanting an app created for you, you will see the advantages that writing your app in Python has for you.
Below are some of the benefits of or reasons why you should use Python.
All Purpose Programming Language: Most programming languages have specific areas of focus or best use. PHP, for example, is best used for building websites and web apps (though in recent times it is evolving into other areas of use.) Python, unlike most others, is a general purpose programming language. It is used for all kinds of applications development. It is used in building great websites and web apps with frameworks like Flask and Django (developed fully in Python), desktop apps, and even mobile applications. Mobile apps development with Python is mostly achieved with the use of frameworks. An example of such a framework is the Kivy framework that has been in existence for several years and has a large community.
Some examples of web apps or companies that use Python include Dropbox, Google, Gmail, Facebook (the company, not the website), Instagram, YouTube and so many more and these are either great companies or products that have stood the test of time.
Best Entry Level Language: Python is one of the easiest programming languages to learn because Python emphasizes code readability. Reading and writing a code in Python is almost similar to writing in any human language. Codes written in Python are also shorter than code written in other programming language. These make learning it a lot easier and faster than learning other languages. And since it’s an all purpose programming language as stated above this is a big win for beginners – one programming language and you’re as good as covered. A number of the top tech schools in the world pick Python as their language of choice for introducing computer science. As a beginner, learning Python means you’re equipping yourself with the same skill as those who are trained in the top tech schools in the world.
Wide Range of Application and Use: The Python programming language is used in a very wide range of industries and across many fields of life. It is used in finance and economics, engineering, the sciences including bio sciences, medicine. Some of its best uses include in data visualization, machine learning, Big Data etc. This, coupled with the fact that it is very easy to learn, makes the language one of the go-to languages for most scientist and professionals. Scientist, doctors, other professionals and even students can learn it in as little time as possible and begin building amazing applications.
Python is Cross-platform: A great benefit of using Python is that Python and applications developed in Python are cross-platform. An application developed on Windows PC will work fine on a Mac and vice-versa. As a programmer this is a major benefit as you do not have to develop different apps for different platforms. One app, many platforms – that’s a plus in time investment. This also decreases development time if you have several platforms in mind when developing.
Turing Complete: Python is Turing Complete. The concepts of Turing completeness is gotten from the Turing Machine invented by Alan Turing. Turing Machines are the most powerful of machines and, if you can program them well, they can solve any mathematical problem. One important quality of a Turing Machine is that it can create other Turing machines. When applied to programming languages, in simple terms, the programming language should be able to write programs that solve any mathematical problems. They should have the capability of simulating any other Turing Machine.
Academically speaking, a programming language is Turing Complete if it meets these conditions:
1. It has the ability for conditional branching, conditional jump or conditional repetition (execution of decisions as in the case of If statements, while and for loops).
2. It has the ability to read and write to storage mechanism (as in the case of variable assignments and others)
These two conditions can be broken down into simpler terms including the following:
1. A Turing Machine can run forever so a Turing Complete language can run forever.
2. A Turing Machine can, technically, make use of infinite memory. A Turing Complete language can use up infinite memory.
3. A Turing Complete language can make or execute infinite decisions as a Turing Machine can make infinite decisions based on the things it sees in memory.
As a programmer this means you have a ‘complete machine’ in the Python programming language with which you can create virtually anything you want.
Shorter Development Time: One of the biggest advantages of Python over other programming languages, for programmers and clients alike, is Python’s shorter development time. We live in a world where everyone wants things to happen fast. Things need to happen fast if you’re going to be relevant or at least keep up. This is one place Python ‘shines above them all’. No matter what it is you’re developing, you can be sure that the code for that program will be a lot shorter with Python than with other programming languages. This is better explained with a simple example so here’s one – the popular “Hello, World” program.
To write a program that prints out “Hello, World” in Java the code is as follows.
public static void main(String args)
The same program in Python is a simple one-liner”
print (“Hello, World”)
This is for just a very small program. What do you think a large program will look like? The difference will be exceedingly clear. Development time in Python will always be many times shorter. As a matter of fact, it is said that one of 2011 Chevy had 11 million lines of code in it. The code was of course written in Java. Think for a moment: How long did it take to write those codes. Meanwhile, if those codes were written in Python, taking a cue from the code examples above, it will not amount to that much lines of code. Maybe just 5 or 6 million lines of codes. While any numbers stated here for the number of lines it would be written in Python is speculative, the fact remains that it will be significantly less.
Time and Money Saved: For Python programmers this means you are able to turnover projects in relatively shorter time which is a good thing as you can easily pick up new projects. For a client this also means that you get to save money as a result of the fact that development time is shorter. You do not only pay for the skill and final product, you pay for the efforts and time investment. And since development time is significantly reduced, money is saved!
There are so many other reasons and benefits why we use Python and why you should use Python too. Besides those explained above some others include a robust standard library, so many open source frameworks and tools, a large active community and multiple programming paradigms. If you are looking for a programming language to learn or use in developing applications, go with Python.
With the ever-growing internet community, the need for full stack development services is on the increase. Hold up, do you even understand what full stack development service is? Well, if not, then this article is at your best interest. Let’s take a look at how this service will help grow your business. In addition, you will also learn the reason why you should work with our expert coder's full stack development team.
What is Full Stack Development Services?
The first thing that comes to mind when people hear the word full stack developer is ‘that is probably another web developer’. The simply dismisses the weight of Full stack development as a simple task. But a full stack developer’s job is more complex than what we tend to imagine.
From a textbook description, a full stack developer is a person who will be able to perform work such as the implementation of the front end of your website, communicating with web services and at the same time providing the storage back end services.
Full stack Development is a web development technique that involves knowledge of both front end and back end applications.
It’s important to note that today you will easily get a person who can ideally give you such services. However, the catch is that you will not get the full expert services you need. It’s a rare thing to find a company with experts who have a deep understanding of those areas.
Most Full stack developers tend to have a shallow understanding of the concept. One of the major reasons is that they typically concentrate on only selected areas, but Full stack development is more than that. For you to qualify as an expert, you need to have enough in-depth knowledge of all sectors of full stack development.
What services will you be getting when you hire our Full Stack Development Team?
From the description above, there are tons of applications in your business for a full stack developer. But before you decide to hire one, let’s look at some of the ways our Expert Coders team will improve your company:
1. UI / UX Development
UI and UX are possibly the most confusing terms in the internet world. And that’s because both terms almost mean the same thing. More to that, UI and UX can be viewed as one entity. It’s quite hard to have a solid difference between the two terms.
UI design basically means user interface design. What’s more, this is the layout of any application. The UI majorly consists of buttons that the user can click on, texts that the user can read, images, text field entries and other items that users interact with.
This will also include the screen transitions, layout, animations and every micro-interaction on the surface of an application. Any sort of visual or animated element that needs development fall in this section.
UI designers can be classified as graphic designers. It’s up to the UI designer to make the application as visually attractive as possible. The theme and purpose of the application should match the needs of the users. They also have to make sure that every single element feels united in both purpose and aesthetic.
On the other hand, UX describes the user experience. In this section, the user experience can be determined by how difficult it is to interact with the designed elements. Additionally, a user’s experience is usually determined by their interaction with the application. That will depend on whether the experience is intuitive or smooth.
At expert coders, our full stack development team have the ability to ensure both the UI and UX elements of your application run as smoothly as possible. The UI determines how the application looks while UX determines how the application works. Both these elements will affect the functionality and effectiveness of your web interface, software, application or any other program that requires user interaction.
With our Full stack development services, you will get the chance to enhance both performances in your software and optimize it. Our full-stack developers will ensure both elements work flawlessly and are perfectly aligned with any of user expectations hence creating an excellent user experience.
2. Back End Services
Back end services are simply handling what happens in the ‘back scenes’ of a web application. This is generally the code that connects the web to a database, powers the web application and manages the user’s connection.
Basically, our back end developer will create the code that will make your website tick. This part of your website will however not be visible to the user. Nonetheless, it exists and contributes a lot to the functionality of any website.
For instance, our back end developer will create the code that makes a button work through figuring out what database is to be fetched by the user. The part where the button will be displayed for the user to click it is left for the front end developer. In most cases, back end developers spend a lot of their time-solving problems and implementing algorithms.
Now, when it comes to Full stack developer, he or she should also have the knowledge of back end services. Meaning, when you hire a stack developer from our team, you will be able to get this service and more. You don’t have to settle for only a back end developer since you will also need other services. That is why looking for a full stack developer from Expert Coders will help you a lot.
He or she will be able to handle both the back end element, front end and UI / UX part of your application. Continue reading and I’ll show you more services that our full stack developer is capable of offering you.
3. DevOps Services
This is a set of services that involves a combination of both technological operations and software development. The term literally stands for Development (Dev) and operations (Ops). However, this term can mean a lot of things to different people in the online community.
DevOps will help increase an organization’s speed to deliver services and applications. This allows organizations to serve customers better and at the same time compete strongly in the entire market.
An Expert Coders full stack developer is able to increase software velocity using DevOps to effectively execute the whole process. Since our team is well qualified and well experienced, the full stack developer will achieve faster time to market using DevOps.

6. ERP &CMS Development
At expert Coders, you get the chance to hire a full stack developer who can help you craft your CMS and ERP. The services you get will be quick, reliable and well facilitated with an intuitive UI. In most cases, the ERP systems are designed for large enterprises that need to handle very large amounts of data. Such data include customer billings and goods.
In case you are still wondering, ERP stands for Enterprise Resource Planning. With an ERP system, you get several small modules that are designed for the purpose of managing the entire enterprise. These modules can be used as a system for accounting, storing, finance, as well as supply management.
These modules, however, are connected to a single database despite the fact that they appear independently. ERP systems do not need any other modules in order to function. I’d say that ERP systems are like desktop applications that are connected to the company’s internal network.
On the other hand, CMS stands for Content Management systems. CMS is a major module in the ERP system although it also operates completely separately. In most enterprises, the CMS system is used to manage the content or a company on their website. Through the CMS, you get to either delete, add or even change any content from their webpage. Also, they can new features or any other user management.
CMS and ERP systems are perfect for any large enterprise. That is why you need to engage our team of experts in getting the best services for your website.
