Articles Related To Good Data


Applying for a data scientist job can be an intimidating task as there can be many things to take care in an interview process — right from justifying the practical knowledge to showcasing the coding skills. While we have earlier discussed articles on how to crack data science interview and what are the things to keep in mind while appearing for an interview for data science-related roles. This article deals with some of the things that you might be doing wrong if ever you are rejected in a data science interview.

 

Here are five things you may have been doing wrong:

 

Not focusing on the job description: The definition of data science jobs is not always the same and may mean different roles and responsibilities for different companies. Some of the commonly required skills may be a PhD in statistics, Excel skills, machine learning generalist, Hadoop skills, Spark skills, among others. The job description largely varies for every company and it is important to thoroughly dig it and carefully look for specific skills, tools and languages. It is important to display the skills that the potential recruiter is looking for so that they can shortlist you easily.

 

No specific distinction of technical skills: The technical skills in data science and analytics industry is quite wide and not mentioning your strengths correctly might jeopardise your chances of cracking the interview. For instance, it might not be apt to just say machine learning skills as it might include a whole spectrum of things ranging from linear regression to neural networks. And these sub-areas might further require knowledge of specific tools and software such as Python, Keras, R or Pandas. It is always advisable to give specific skills that you master than describing generic skills as might confuse recruiters of the exact skills that you pose.

 

Incorrect information and rephrasing work experience: To suit the data science job roles, many a times candidates rephrase their previous work experiences such as in the IT or software domains to present it as data science job roles, which might disguise your abilities initially but expose the depth and understanding of the skills later. You might have included job description aligning in a way that suits data science job roles but you might not have a deeper experience in it, which may get noticeable by recruiters during a one-to-one interaction. Mentioning of incorrect or misleading facts may also lead to recruiters rejecting you. For instance, the resume may state achieved an accuracy of say 90% on the test run, but what are the baseline and state-of-the-art score for this dataset to claim these numbers?

 

No mention about the projects that you have worked on from the scratch: Many times the only projects that a candidate mention in a resume are the ones they have done on Kaggle. While Kaggle is a platform for a lot of researchers to explore avenues in data science, it also serves as a source of practice for people who aren’t a pro in data science field and are trying to make a transition, mentions a recruiter in one of the forums. There are different kinds of the audience at Kaggle such as those who are playing around with the dataset or getting to know how problem-solving in data science works like, without having actual experience in solving or creating a new data science problems. So, listing just Kaggle project might be good but not definitive of how good your data science skills are. Even if it a Kaggle project, it is better if it is done from scratch. Other than that, it is important to mention the projects that you have worked on. It gives recruiters a chance to understand the problems you faced and the way you approached the problem, thereby giving them a glance at your problem-solving abilities.

 

The resume is full of buzzwords and no concrete proof of your skills: While the resume may suit the job description, but there are chances that you are rejected if there are too many buzzwords in the resume and no concrete way to prove that you actually pose those skills. You may mention in the resume that you have had experience with Hadoop, Excel or certain areas, but if you have showcased it real-time on platforms such as GitHub, it convinces the potential employers of the skills you have. They can look through various projects you have been a part of and see how you have dealt with real data. Hiring managers like to see the time that a candidate has spent from start to finish. Having a portfolio gives recruiters just that. There may be fancy sounding terms in the resume, but if you don’t have a proof to showcase it, you might be rejected for a potential data science job role.

Nowadays, Android is not just on tens of thousands of different phones and tablets. It’s on your wrist, in your living room, in your car, and as soon we start assigning IP addresses to inanimate objects, it is going to be pretty much everywhere around us. A lot of ground for even an experienced Android developer to cover!

 

Also there are over one million apps on Google Play, not counting Amazon AppStore or markets we are not generally interested in.

 

So, how can an independent developer create a successful app in this huge market with big players? I have no idea, I haven’t made a successful app! But, I have made a cute one, and I’d like to share my story with you.

Few Android Studio Tips, Tricks & Resources you should be familiar with, as an Android Developer

The reason of this article, is to list helpful tips, tricks, shortcuts and resources for Android Studio that will improve your overall efficiency and performance.

 

1.Material Colors theme for Android Logcat

To change Android Studio Logcat you need to go to:Preferences (Settings on Windows / Linux machines) → Editor → Colors & Fonts → Android Logcat and change the foreground color for every type of log.

 

2. Prevent Android Studio Logcat from clearing the log for the current application when it crashes. 

To do that you need to go to theAndroid Monitorpanel and chooseEdit filter configurationon the right side dropdown.

 

3. Apply a proper code style to your IDE (IntelliJ / Android Studio). 

Go toPreferences → Code Style → Javaand in aSchemedropdown you can choose your code style (or set up a new one).

2 styles which are especially worth to mention:

Square Java Code Styles with Android

Google Java Code Style.

 

4. Use split screen for increasing efficiency.

To turn this feature on, you need to right mouse click on the tab of your main screen and choose Split Vertically / Horizontally feature.

But to be as efficient as possible we need to set up a custom keyboard’s shortcut. To do that go to Preferences → Keymap and search for Split Vertically. Then open a context menu and click Add Keyboard Shortcut

It is shown on a gif below. You can define the shortcut for a horizontal split view as well.

 

5. Distraction Free Mode. 

You can enable it by going to: View → Enter Distraction Free Mode

 

6. Use Live Templates

you can use many already defined templates, like for Toasts or if conditions.

you can use your own custom templates. Here is a great reference article by Reto Meier. You can also refer to the IntelliJ IDEA documentation.

 

Learn XML And Java

Extensible markup language (XML) is a markup language that’s the foundation for the Android user interface (UI) and elements. Java is the back-end coding language of the Android platform, and it’s used with binding functionality with your XML layouts. Let’s take a look at a small example.

 

<?xml version="1.0" encoding="utf-8"?> <layout xmlns:android=http://schemas.android.com/apk/res/android"> <data> <variable name="user" type="com.example.User"/> </data> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.firstName}"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.lastName}"/> </LinearLayout> </layout>

 

This small layout has one data object defined as “User.” For developers used to binding elements in even web design, this should be intuitive for you. The data element is defined in Java, and then the object data is bound to the front-end layout element. In this example, we have a first and last name. The following Java code is an example of a User class used for the binding.

 

public class User { public final String firstName; public final String lastName; public User (String firstName, String lastName){ this.firstName = firstName; this.lastName = lastName; } }

Notice that the constructor takes a first and last name variable and binds the data to the public class properties. When the screen opens on the device, this data is then bound to the front-end elements.

 

Before you get started in Android Application development, you should be expert in both of these technologies. Understanding the fundamentals of XML formats is relatively easy, but Java is an object-oriented language and object-oriented programming (OOP) can be challenging if you’re not familiar with the concept. A newer language and framework, Kotlin, has been introduced to help advance Android app development. It can also be used with legacy Java apps as Kotlin co-operates with Java code.

 

The best way to learn Java is to dive into someone else’s code. GitHub is filled with open-source projects that help you understand Java and OOP concepts. The better your OOP skills are, the easier it will be to create a better coded, less buggy Android app.

 

Understand Memory Limitations

Mobile devices don’t have the high memory limitations that desktops have. In mobile programming, you must learn to code with smaller memory limitations in mind. If you carelessly use memory on an Android device, you run the risk of your app crashing due to “out of memory” errors.

To work around this, use services on the device sparingly and release memory resources when your app is hidden. You can release memory resources by overriding the onTrimMemory event although you should know that this isn’t a magic solution that allows you to ignore other performance optimization throughout your code. The following is a small sample of pseudocode that shows you how to override the event.

@Override public void onTrimMemory(int level) { if (level >= TRIM_MEMORY_MODERATE) {

//release resources here } }

Google also recommends that you avoid or at least reduce the use of bitmaps to lower the memory use when your app is running on the device. 

 

Don’t Use The Emulator For Real-World Testing

The Emulator in Android Studio is good for development and even debugging, but it doesn’t fully simulate a working Android device. You can consider basic environment features with the Emulator, but when it comes to testing, you should always use actual devices.

Of course, this is a huge investment for an Android developer, but it will make the entire development and testing life cycle much more efficient. It also ensures that you’re able to test your applications in various conditions as the user changes settings on the actual device. You can, however, use automated cloud solutions such as Amazon’s Testing platform.

 

Testing should never be taken lightly. It should be a major part when you design and deploy apps for your clients. Fewer bugs means happier users, and it can also mean a more successful app in Google Play. This doesn’t mean that you need to buy every device on the market to test your app on, but you should account for some of the more popular ones and the most common screen sizes.

PHP (recursive acronym for PHP: Hypertext Pre-processor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

PHP is one of the main languages used in dynamic web development. It’s one of the oldest language and a common component in the LAMP stack (Linux, Apache, MySQL, PHP). If you want to create a website or any back-end web service, PHP is one of the main languages you can choose from. If you need revisions to an existing application that runs on a Linux server, it’s common for the back-end coding to be done with PHP.

About PHP Developers

PHP developers are often simply called “back-end engineers.” A PHP developer is responsible for writing server-side web application logic. PHP developers usually develop back-end components, connect the application with the other (often third-party) web services, and support the front-end developers by integrating their work with the application.

They’re turn client’s specifications into a workable, tangible product that runs on a web server. Although PHP can run in a Windows environment, it’s more commonly used on Linux servers with Apache running as the web client. Many PHP developers package their applications this way with Linux and Apache to make it easier for the client to host it.

PHP developers code the functionality and brings an app to life. Collaborating with designers, they ensure that the front-end application is appealing to users. You may find that some PHP developers have front-end design skills, but often times, they work with UI and UX designers to create a user interface that’s engaging and supported by solid back-end functionality.

What Can You Expect from a PHP Developer?

It is a PHP Developer's job to write, test and maintain the code for web pages and computer graphics programs. They use PHP, a widely used scripting language, to build websites, programs and applications that computers follow to perform functions. They are also responsible for writing, troubleshooting, testing and maintaining the source code for computer programs. If needed, PHP Developers also assist team members in problem solving.

A PHP developer should be able to visualize your application and what you need based on your conversations and documentation (if you have any). They should be able to understand your business so that they can provide you with an application that supports your goals and business logic.

PHP developers mainly create two types of applications: web apps with a database background, and APIs that provide your existing software and data to mobile apps and other developers. PHP code powers the back end of a web app, so a PHP developer will design and architect your code and the way it works to support the front end. APIs are often used when developers or apps need to query your internal data, and they allow you to provide this data to the outside world. For instance, your app might pull a list of tweets from Twitter’s API. A PHP developer will read the API documentation and implement it into your website. APIs are also used with some mobile apps to power the app’s data services.

Deliverables could be full source code files, or some developers help you upload the code to your web server of your choice choice. If you’re building a website from scratch, it’s vital that you choose a developer with the skills necessary to tackle a project from the ground up. A senior-level developer will know how to manage a project (they might assign a project manager), set expectations, estimate costs, and give you organized, scalable code that you can work with for years.

Just like other development areas, PHP developers have a variety of skill sets and levels. Senior-level PHP experts often have several other languages in their arsenal. They should be able to design a full application from the ground up. Junior-level developers have a few years of experience, but they often need to work with, or have their work reviewed by, a senior-level developer to ensure that code is efficient and properly written.

Defining Your Project

A developer can only do as good of a job as the specifications or information they get from the client. Communication is key so that your PHP developer fully understands your concepts and goals. When you post a project, you must be able to communicate key elements so that you can get the best estimates from the best developers.

Before you post a project request or talk to developers, you should sit down and map out your idea. This can be done using images, presentations, or other types of documentation. For instance, you can draw your own wireframes and then explain each concept in writing. Developers bidding on your project can get a better idea of what needs to be done and estimate far more accurately.

It can be difficult for a client to understand the duration of a project and its cost, but a developer can sit down and discuss project scope, a reasonable timeline, and any deliverables that you can expect during the project’s development process.

Writing a Project Description

Once you know what you want from your end product, it’s time to write your project description. You need to be concise but provide enough detail to attract top developers. You can attach documents and provide video links to your project description to help developers better understand your goals.

Below is one sample of how a PHP project description may look. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When engaging a freelancer as an independent contractor, you typically just need a statement of work, job post, or any other document that describes the work to be done.

Title: PHP Developer Needed to Build E-Commerce Website

Description: We need a PHP developer to build an e-commerce platform for our website. We have a rough wireframe document that explains the front end and the back end. We need help determining back-end architecture, so we want a developer to determine the way it will be built. We currently have hosting and need help uploading the code after it’s finished. The e-commerce store will host our product catalogue, take orders, allow customers to sign up, and then send email reminders to customers that left products in their shopping cart.

You can modify this description to better fit what you’re looking for, but it gives the basic requirements that a PHP development project might have.

PHP projects can take a long time, so expect a big project to take several months. PHP projects may require sit-downs to understand your requirements, design, coding, prototyping, and testing. All of these extend the deadline and can require several months for larger projects. A developer might even add a small percentage of time to the duration to ensure that deadlines are met. As with any project, the more descriptive your post is and the more you communicate with your programmer, the smoother the process will be.
