3 Python Packages for Interactive Data Analysis

What Is Data Analysis?Although many groups, organizations, and experts have different ways to approach data analysis, most of them can be distilled into a one-size-fits-all definition. Data analysis is the process of cleaning, changing, and processing raw data, and extracting actionable, relevant information that helps businesses make informed decisions. The procedure helps reduce the risks inherent in decision-making by providing useful insights and statistics, often presented in charts, images, tables, and graphs.Why is Data Analysis Important?You Get More Accurate DataBetter Problem-Solving MethodsReduce Operational CostsBetter Customer Targeting3 Python Packages for Interactive Data Analysis1. PandasGUIPandasGUI is a simple Python Package that provides GUI for dataset exploration. The package offers a separate GUI with an excel-like experience we could use to explore the dataset, acquire the statistic, visualize the data, and many more.2. D-TaleD-Tale is a Python package for interactive data exploration which uses a Flask back-end and a React front-end to analyze the data easily. 3. MitoLet’s try to install the Mito package. Mito is a Python Package that transforms your data frame into an excel-like analysis data frame. Any data person does data analysis because it is the required step. Sometimes, we want a more interactive way to analyze the data. To do that, here are 3 Python packages to do interactive data analysis

Tips for getting a job as a software developer

Software developers use their programming skills to create new software and update existing applications. If you’re a creative thinker who enjoys problem solving, a career as a software developer could be a good fit.1. Learn a programming language.For a career in software development, you'll need a solid foundation in programming languages Four you might consider mastering include Java, Python, C++, and Scala. 2.Make a portfolio of your software development work.As you practice programming and build applications, compile them into a portfolio. Having a portfolio of your best work demonstrates to potential employers that you can use the skills on your resume in the real world. At a minimum, your portfolio should contain:Short biographyContact informationRelevant skillsLink to your resume3. Develop your technical skills.Beyond programming languages, it helps to have experience working with other tools that software developers commonly use. Examples include:SQL, a language used to power database enginesTools like Git and Mercurial SCM, two source control systems often used in software development4.Certify your skills. Certifications can help validate your skills for potential employers and demonstrate your proficiency, which can be helpful if you don’t have a lot of work experience. For example, the CompTIA IT Fundamentals+ certification is a good starting point to help get a sense of whether a career in information technology (IT) is right for you. From there, consider certifications in data security, cloud computing, or data management.

Microsoft confirms hacking group stole source code via 'limited access'

Microsoft has confirmed claims made earlier this week by hacking group Lapsus$ that it was the victim of a cybersecurity incident. Redmond seemingly dismissed the matter as no big deal, noting it was already looking into the issue before the group went public and downplaying the importance of secure source code.A blog post addressing the matter notes that Microsoft's investigation uncovered a single account had been compromised, which granted the attacker "limited access." According to Microsoft, their team was already investigating the compromised account when Lapsus$ publicly disclosed the intrusion.If you recall, the group released a dump earlier this week containing around 37GB worth of Microsoft data. The haul reportedly included portions of source code for Bing, Bing Maps and Cortana.Microsoft said it "does not rely on the secrecy of code as a security measure," adding that viewing source code does not lead to an elevation of risk.Microsoft also touched on some of the group's preferred tactics, many of which aren't all that common among threat actors. Examples include phone-based social engineering, SIM-swapping, accessing personal e-mail accounts and even paying employees, suppliers or business partners of target organizations for access to credentials or multi-factor authentication (MFA) approval.Redmond additionally provided tips that organizations and individuals can use to protect themselves, including using MFA, avoiding phone-based MFA methods and leveraging passwordless authentication like Windows Hello, Microsoft Authenticator or FIDO tokens.Lapsus$ has been extremely busy this year, having already hit big tech targets including Nvidia, Samsung and Vodafone. Authentication firm Okta has also fallen victim, with the company updating its statement to confirm that around 2.5 percent of its clients have potentially been impacted and whose data may have been viewed or "acted upon."

5 Reasons to Learn Java Programming

Created by - Sethu Lakshmi Sankar

5 Reasons to Learn Java Programming

Java is one of the best programming languages created ever1. Java is Easy to learnMany would be surprised to see this as one of the top reasons for learning Java or considering it as the best programming language, but it is. If you have a steep learning curve, it would be difficult to get productive in a short span of time, which is the case with most professional projects.2. Java is an Object-Oriented Programming LanguageJava is a high-level, object-oriented programming (OOP) language. Object-oriented programming languages are used by programmers to structure classes, which are used to create objects (bits of data and code). This is what makes it different from functional programming languages such as Python, which cannot store data in objects. Java can also run on any device with Java Virtual Machine (JVM), which contains a compiler used to create byte code and is available on many operating systems. 3)Powerful development tools like Eclipse, NetbeansBelieve it or not, Eclipse and Netbeans have played a huge role in making Java one of the best programming languages. Coding in IDE is a pleasure, especially if you have coded in DOS Editor or Notepad.They not only help in code completion but also provides a powerful debugging capability, which is essential for real-world development. Integrated Development Environment (IDE) made Java development much more comfortable, faster, and fluent. It's easy to search, refactor, and read code using IDEs.4)Great collection of Open Source librariesOpen-source libraries ensure that Java should be used everywhere. Apache, Google, and other organization have contributed a lot of great libraries, which makes Java development easy, faster, and cost-effective.5)It’s Inexpensive to LearnYou do not need to have a bachelor’s degree in computer science to learn Java syntax. According to a Stack Overflow survey, only 9.1% of professional developers consider formal education critically important to become a developer.
