Now a days, the popularity of scientific computing environments such as IDL, Maple, Mathematica, Matlab and R has increased considerably. Engineer simply feel more productive in such environments. One reason is the simple and clean syntax of command languages in these environments. Another factor is tight integration of simulation and visualization in Maple, R and similar environments you can quickly and conveniently visualize what you just have computed. One problem with the mentioned environments is that they do not work, at least not in an easy way, with other types of numerical software and visualization systems. Many of the environment specific programming languages are also quite simple or primitive. At this point scripting in Python comes in.

 

Python offers the clean and simple syntax of the popular scientific computing environments, the language is very powerful, and there are lots of tools for simulation, visualization, and data analysis programs. Python allows you to build your own Matlab like scientific computing environment, tailored to your specific needs and based on your favorite high performance FORTRAN, C, or C++ codes.

 

Scientific Computing Is More Than Number Crunching: Many computational scientists work with their own numerical software development and realize that much of the work is not only writing computationally intensive number-crunching loops. Very often programming is about shuffling data in and out of different tools, converting one data format to another, extracting numerical data from a text, and administering numerical experiments involving a large number of data files and directories. Such tasks are much faster to accomplish in a language like Python than in FORTRAN, C, C++, and C#.

 

Scripting is particularly attractive for building demos related to teaching or project presentations. Such demos benefit greatly from a GUI, which offers input data specification, calls up a simulation code, and visualizes the results. The simple and intuitive syntax of Python encourages users to modify and extend demos on their own, even if you are newcomers to Python.

 

Python has some clear advantageous over Matlab and similar environments:

  • The Python programming language is more powerful.
  • The Python environment is completely open and made for integration with external tools.
  • A complete toolbox/module with lots of functions and classes can be contained in a single file.
  • Transferring functions as arguments to functions is simpler.
  • Nested, heterogeneous data structures are simple to construct and use.
  • Object-oriented programming is more convenient.
  • Interfacing C, C++, and FORTRAN code is better supported and therefore simpler.
  • Scalar functions work with array arguments to a larger extent (without modifications of arithmetic operators).
  • The source is free and runs on more platforms.

 

How to run Python script

One of the most important skills you need to build as a Python developer is to be able to run Python scripts and code. This is going to be the only way for you to know if your code works as you planned. It’s even the only way of knowing if your code works at all!

 

A Python script is a reusable set of code which is essentially a Python program or a sequence of Python instructions contained in a file. You can run the program by specifying the name of the script file to the interpreter. 

 

This step-by-step will guide you through a series of ways to run Python scripts, depending on your environment, platform, needs, and skills as a programmer. When you try to run Python scripts, a multi-step process begins. 

 

  1. Run Python Scripts Using the Command-Line: A Python interactive session will allow you to write a lot of lines of code, but once you close the session, you lose everything you’ve written. That’s why the usual way of writing Python programs is by using plain text files. By convention, those files will use the .py extension. Open a command-line and type in the word ‘python’ followed by the path to script file and press enter. You’ll see output on your screen.
  2. Run Python Scripts Interactively: It is also possible to run Python scripts and modules from an interactive session. This option offers you a variety of possibilities.
    • Taking advantage of import
    • Use importlib and imp
    • Use runpy.run_module()
    • Hacking exec()
    • Use execfile()
  3. Run Python Scripts from an IDE or a Text Editor: IDE offer the possibility of running your scripts from inside the environment itself. It is common for them to include a Run or Build command, which is usually available from the tool bar or from the main menu.
  4. Run Python Scripts From a File Manager: Running a script by double-clicking on its icon in a file manager is another possible way to run your Python scripts. This option may not be widely used in the development stage, but it may be used when you release your code for production.

 

After you play around with Python on your own or in an online tutorial, I highly recommend to you to write small scripts to strengthen your knowledge. To stay motivated, choose a program that is in some way useful to you, so you can gain insight while figuring out Python. Below are a few ways you can begin to build your expert level in Python script:

 

  • Python Documentation
  • Google and stackoverflow
  • Ask an experience person

 

First, create a very basic version end-to-end. It is much less frustrating than trying to build a super-duper version from scratch. A big plus is that you will have something you can use very fast. Then iterate and add more complex functionality one by one.

 

Second, decompose large problems to smaller ones by introducing functions. Small, cohesive functions are easy to understand, test and debug.

 

Last, but probably the most important thing to keep in mind, is practice makes perfect. Start small, be patient and practice. Happy coding!

Picking the right company structure for your business is as important as any other business-related activity. The right business structure can allow your enterprise to control efficiently and meet your required business targets. In India, each business should register themselves as a part of the necessary legal compliance. Before we tend to learn how to register a company, let’s try and understand the types of business structures in India.

Types of business structure in India:

  1. One Person Company (OPC): It is the simplest way to start a company if there exists only 1 promoter or owner. It allows a sole-proprietor to hold on his work and still be a part of the company framework.
  2. Limited Liability Partnership (LLP): This kind of business structure was essentially formed to provide limited liability to its owners. To become a partner of LLP doesn’t involve a huge lengthy complicated method. It’s simple to form as well as simple to become a partner. In it, each partner has limited liability to the extent of capital contributed by them. They don’t have to suffer on behalf of its other partners.
  3. Private Limited Company: A Private Limited Company is that company which is owned privately by the individuals. It is more flexible and easy to form than a Public company. It can be formed with just 2 members and 2 directors. But there is a restriction in the maximum number of its partners which is restricted to 200. The number of shareholders is limited to 50 only. A Private company cannot invite public to apply for its shares. This kind of company is more preferred by investors because they can buy/sell stakes easily.
  4. Public Limited Company: A Public Limited Company is that company which is owned by public or in which the public can subscribe. The minimum number of directors is 3 and the minimum number of shareholders is 7. There is no limit on the maximum number of shareholders. The shareholders have limited liability to the extent of the face value of its shares and the premium respectively.

Steps for registration of new company

Obtain Director Identification Number

Director identification number is a unique number allotted by Central Government to any person assuming to be a director or existing director of company in India. Director identification number is 8 digit unique number which has a lifetime validity, details of director are maintained in database through this number.

Whenever a return, an application or any information associated with a corporation or company are going to be submitted under any law, the director signing such return, application or information will mention his Director Identification Number underneath his signature.

Procedure to obtain DIN: There are three different forms

1.      Spice Form (Application Of First Directors In Case Of New Companies): SPICe form is used by the first directors of new companies. The intended person who has not obtained DIN shall make an application through eForm SPICe. The documents which  need to be attached are

·         Proof of identity

·         Proof of address

2.      DIR-3 Form: Any person intending to become a director in an already existing company shall have to make an application in eForm DIR-3 for allotment of DIN.

·         Procedure to obtain DIR-3 Form: The form shall be mandatorily signed by the applicant and the same shall be verified digitally by a:

·   Company Secretary (who is fulltime employment of the company)

·   Managing director or manager.

·   Chief Executive Officer or Chief Financial Officer.

Two supporting documents need to be attached that is:

·   Photograph of the concerned applicant.

·   Proof of identity and Proof of residence.

3.      DIR-6 Form: DIR-6 Form is used by the directors when there are any changes in the particulars of the directors. The form shall be signed by the applicant and certified by a Chartered Accountant, Company Secretary, Cost accountant (whole time practice), Director of an existing company.

Obtain Digital Signature Certificate

A Digital Signature Certificate is a secure digital key that is issued by the certifying authorities for the purpose of validating and certifying the identity of the person holding this certificate. Digital Signatures make use of the general public key encryptions to create the signatures. A digital signature certificate (DSC) contains information concerning the user’s name, pin code, country, email address, date of issuance of certificate and name of the certifying authority.

A Digital Signature Certificate (DSC) explicitly associates the identity of an individual/device with a two keys - public and private keys. The certificate contains data about a user's identity (for example, their name, pincode, country, email address, the date the certificate was issued and also the name of the CA. These keys will not work in the absence of the other. They’re used by browsers and servers to encode and decode data concerning the identity of the certificate user.

The private key is stored on the user's computer hard disk or on an external device like a USB token. The user retains control of the private key; it will solely be used with the issued password. The public key is disseminated with the encrypted data. The authentication method fails if either one of these keys in not available or do not match. This means that the encrypted information cannot be decrypted and so, is inaccessible to unauthorized parties.

Procedure to obtain digital signature certificate

  1. Submission of DSC Application form duly filled in by the applicant. Any individual applying for a Digital Signature Certificate is required to fill an Application Form for online submission and verification of personal details by the certifying authority.
  2. Producing Photo ID proof
  3. Producing  Address proof
  4. To fill in the Application form the please log in to the website of the Certifying Authority.

Register a Company Name

Tips for naming your startup company:

  1. Avoid hard to spell, you don’t want potential customers getting confused concerning how to find your business on-line. You would like to avoid having to continually correct the misspelled version of your name. Keep it simple.
  2. Don’t pick a name that could be limiting as your business grows.
  3. Once you have determined a name you like, do a web search on the name. You will find that someone else is already using that business name.
  4. Use the most secure “.com” domain name for your business rather than alternatives such as .net, .org, .biz, or other possible domain extensions.
  5. You want the business name to convey something meaningful and positive related to your business.
  6. Make sure you are personally happy with the name.

To register your company, you will file your completed application online with the Indian government’s Registrar of Companies, or RoC. The RoC, which is under the jurisdiction of the Ministry of Corporate Affairs, oversees the incorporation of new companies and the administration of businesses under the statutory regulations of the Companies Act.

Check online to see if your choice of company name is available. Before you file your application to register your company, it’s a good idea to have your company names firmly in place to ensure the registration process isn’t hindered.

Get Certificate of Incorporation

A Certificate of Incorporation (COI) is a legal document that is issued by Ministry of Corporate Affairs (MCA) once a Company is successfully registered with them. The COI is a proof that the company is now registered with the Registrar of Companies (ROC).

COI issued consists of a date which depicts the date from which the company is deemed to be official registered. It can then commence its business and start working. Unlike sole proprietorship registration of private limited company is mandatory. It is the duty of the promoter to apply for a COI.

Obtain Permanent Account Number

Permanent Account number (PAN) refers to a ten-digit alphanumeric number, issued in the form of a laminated card, by the income tax Department in India. it is a must to have a PAN number for all those who file their income tax returns, because from 2005 onward, it has been made mandatory by the income tax Department to quote the PAN on return of income as well as on all correspondence with any income tax authority in the country.

Registration of GST

GST is the biggest tax reform in India, tremendously improving ease of doing business and increasing the taxpayer base in India by bringing in millions of small businesses in India. By abolishing and subsuming multiple taxes into a single system, tax complexities would be reduced while tax base is increased substantially. Under the new GST regime, all entities involved in buying or selling goods or providing services or both are required to register for GST. Entities without GST registration would not be allowed to collect GST from a customer or claim an input tax credit of GST paid and/or could be penalized. Further, registration under GST is mandatory once an entity crosses the minimum threshold turnover of starts a new business that is expected to cross the prescribed turnover.

Android is the world’s most popular mobile OS in the mobile market. From phones and watches to cars and TVs, customise your digital life with Android. Many companies preferred Android to begin mobile application development, or entering to the mobile development market because it has a lower cost barrier than iOS. 

Android is an open source software stack for a wide range of mobile devices and a corresponding open source project led by Google. The Android Open Source Project (AOSP) repository offer the information and source code you need to create custom variants of the Android stack, port devices and accessories to the Android platform, and ensure your devices meet compatibility requirements.

Now, it’s time to find and hire a developer to turn your creative and amazing ideas into a tangible app. Here’s a look at what Android developers do so you’re prepared to hire the best one for your Android project.

 

What Does An Android Developer Do?

An Android Developer designs and builds advanced applications for the Android platform and has a solid understanding of the full mobile development life-cycle. Through their creations they give the companies they work for the best opportunity to reach users and make an impact worldwide.

An Android developer is in charge of developing applications for devices powered by the Android operating system. They have a strong understanding of the patterns and practices that revolve around such platform. Moreover, they ensure the best possible performance, quality, and responsiveness of the application.

An Android developer takes project specifications and turns them into a tangible application that can be submitted and published in the Google Play store. Most mobile app projects have a design phase, a development phase, and a submission process. Many Android app developers are “full stack,” handling both design, UI and app coding, but you may choose to have both a designer and a programmer on your app’s development team. Just note that UX (user experience) and UI (user interface) design are two different skill sets that are important for the success of your project. If you decide to hire separate contractors for each component, you need one for UX and one for UI.

Android developer skills are separated into three levels depending on their experience. Developers start at the junior phase for the first few years, although the number of apps they’ve developed and the apps’ complexity are far more important when you determine the right developer for your project. After working alongside more experienced developers, they move to the intermediate phase where they can work on more projects independently. After several years working with complex Android applications, a developer is considered senior level. A senior developer can not only code a project, but they can also make decisions about how to design products. All Android developers should be familiar with:

 

  • Android Studio
  • Android Material Design Guidelines
  • Java and the Android SDK
  • The Emulator
  • Publishing to the Google Play Store

The developer you need will be determined by your project requirements. If you’re creating a new app from scratch, you’ll need a senior-level developer with the experience to take the project from the beginning and see it through to completion. Junior and intermediate level developers are beneficial for small changes, but a senior developer should review the code before it’s put into production.

 

How To Define Your Android Project

To find the right freelance developer, you need to write the project with as much detail and documentation as possible. This could be better for developer to choose the right track to start the work. Android Studio makes it easy to create Android apps for various form factors, such as handsets, tablets, TV, and Wear devices. 

This article shows you how to start a new Android app project or import an existing project with your developer. Two major things to learn before start to work on the project. 

 

  1. Are you creating an app from scratch?
  2. Do you have an existing app that needs some bugs fixed?

Define your criteria. What kind of freelance developer you need (Junior or Senior) This enables you to describe the tasks to be done with runtime alerts and notification using the Toogit Project Management Tool, this gives you some direction on development level.

 

Next, Evaluate what type of challenges freelance android developer may face. This evaluation is most important to write the timeline for your project.

 

Toogit have more experienced android developers. They should guide and develop your project with a professional way. Always remember that more experienced Freelance Android developers on Toogit may charge more even for simple requirements. If you don’t have any understanding of the development process, it might be better to stick with a senior-level developer. A senior-level developer can help guide you through the process.

 

If you have a smaller budget and simple bug fixes or additions, you can specify that you need a junior-level or intermediate-level developer, but remember that they may not have the skill set to see a larger project through to completion.

 

The final aspect of your project to mention is its duration (time and cost) it will take to complete. Android development projects can take a week, a month, six months, or more. The duration is often determined by the developer based on your project description, but you can at least provide an estimate or a deadline, if applicable.

 

Once you get an estimate of how long the project will take, work with your developer to break down the project into releases if you have a flat-rate cost estimate. You can break the project into phases and ask for specific deliverables by particular deadlines.

Example phases include the following deliverables:

 

 

Your Android Application Project Description Writing Guide

How you can write a brief and attractive Android Mobile Application Job description and post it for free? This guide will help you. The way you write a description will determine the quality of developer that you’ll attract. It’s important to write a detailed desciription of job which helps to build the top android the developer interaction in your project and they submit proposals with fairly accurate cost and time estimates on Toogit.

 

The title of your project description can include the type of development that you need. You know that you need an Freelance Android developer, but do you need a designer and a programmer? Do you need someone who understands a specific framework and the latest versions of android? The title should pull best Freelance Android developers with a specific skill set.

 

Next, What type of application do you want developed (gaming, educational, entertainment, etc.)? If you have documentation / excel / slides / pdfs or referrence URLs that shows basic wireframes or ideas, you can include these in your project description. Describe the project in simple and straight way with key points & modules it gives a developer a good sense of the work to be done. If you need the developer to sign an agreement, you can also specify this requirement in your description.

 

Part of your description should also define the deliverables including any designs, APIs, and full source code that can be uploaded to the Google Play Store. The source code is usually delivered using a version control solution such as Git, and then it can be uploaded to Google Play. You might not know the skill set level that you need, but being descriptive will help providers determine if they have the right experience for your project.

Sample

Below is a sample of how a project description may appear.
