Explained: What does a full stack web developer do? Why is the role controversial?
One big misconception, a full stack web developer is an empty title or someone like ‘jack of all trades, master of none’. So not true! What skills a full stack developer must have or acquire? What are the core responsibilities? What programming languages full stack developers must know? Do you know the average salary of full-stack developer in US? The average salary base is $105,556 / year – Indeed A confusion raises as if they will be doing the development or management or responsible for handling the end product/service? Well, almost all of this and more. In this blog post, we will try to cover what is a full stack developer and what skills/role he has to perform in product/ project development in detail. What is a full stack web development? Someone who works on the backend (server-side), and the frontend (client-side). In short, someone who can play in a variety of coding niches either related to databases, web design or user experience, can guide in the best way possible. While looking into the responsibilities of the full stack web developer, he is the one who helps in the design and development of software. Test and debug software for optimization purposes, write clean standard code both for front and back end applications. He can design interactions on the web apps, build databases and servers for backend software running. Looks into cross-platform compatibility of applications, maintains the responsiveness of given design, research and can add new features in a product, develop APIs and RESTful services, reduce security risks and help in scalability. Why is the role of full stack developer...
Decoding the Top 10 Data Science Jargons For Beginners (Commonly Asked In Interviews) | by Sharan Kumar Ravindran | Dec, 2021 | Towards Data Science
This article is about decoding some of the popular jargon used in data science. It is important to understand these concepts better. They are commonly asked in data science job interviews. Let’s get into the topics. Dependent and Independent Variables A dependent variable (target variable) is driven by the independent variables in the study. For example, the revenue for a retail store depends on the number of customers walking into the store. Here the store revenue is the dependent variable. The number of customers walking into the store is the independent variable. The dependent variable is called so because its value depends on the independent variable. Also, independent variables are called so because they are independent of other variables that could impact the dependent variable. Like, the amount of rainfall (independent variable) is independent of the number of customers walking into the store. Both these independent variables help in making a better prediction. While working on a predictive data science problem. There would be generally one dependent variable and multiple independent variables. Below is a very good resource to better understand dependent and independent variables. An outlier is a value that is not within the normal range for a variable. For example, the average life expectancy is around 70 years. An individual who is of age 119 is considered an outlier because his age is well outside the normal range. While working on a data science problem, it is a general practice to check for outliers in the dataset. Outliers in data could impact the choice of the algorithm in case of a predictive problem. Here is a detailed...

Myanmar Junta Set to Pass Draconian Cyber Security Law
Myanmar’s military junta is reportedly on the brink of passing its long-threatened cybersecurity law, which in its latest form would outlaw virtual private networks (VPNs), throttle access to social media networks, and force internet companies to hand over user data to the military. The latest version of the Cyber Security Bill, which updates a draft released in February 2021, comes a year after the military seized power, plunging the country into a zero-sum struggle between the junta and a loose coalition of opponents. According to a report last week by Myanmar Now, the military administration submitted a revised version of the bill to stakeholders on January 13 and called for their feedback by January 28. The law is expected to be passed this week. The February 2o21 draft was widely criticized for compelling internet providers to prevent or remove any content deemed to “cause hatred, destroy unity and tranquility,” any “untruthful news or rumors,” or anything that is “inappropriate” to Myanmar’s culture. It also forced internet providers to gather the personal data of users, store it for three years starting from the day of usage, and hand it over to military authorities upon request. While the draft was withdrawn due to the strong opposition of Myanmar’s business community, the advocacy group Free Expression Myanmar (FEM) (which has also released an unofficial translation of the legislation) claims that the military’s new draft “repeats the repressive provisions of previous drafts and adds more, seriously threatening the safety and security of Myanmar’s digital space.” Diplomat Brief Weekly Newsletter Get briefed on the story of the week, and developing stories to watch across...

A Practical Guide to Cyber Security for Non-Professionals
A PRACTICAL GUIDE TO CYBER SECURITY FOR NON-PROFESSIONALS “Why does security matter?” is a question that has progressed from community bystanders to boardroom discussions, and it does not end there. It is currently the topic of debate in the industry. Everyone we know is talking about security in some capacity, whether at work or elsewhere. Nowadays, cybersecurity is no longer solely the responsibility of an IT administrator or security administrators in an IT organization. It is now a requirement for everyone, even those individuals who don’t work in large enterprises or carry significant amounts of data on their mobile devices. Over the last decade, the use of organizational computer networks, desktop computers, and the internet, in general, has increased exponentially. It has increased the number of threats from malware, viruses, and hackers looking for vulnerable, sensitive information from all sources. So with that in question, how can someone with little to no information regarding cybersecurity know its importance? Sure, there are plenty of books out there that will show you the nitty-gritty details of cybersecurity, but not everyone has the time and will to read a book – right? So for those who are new to the concept of cybersecurity, here’s a practical guide that contains everything you need to know about it. What is Cybersecurity? Before we begin to get to the depth of everything, let us first define cyber security and its importance. Cybersecurity refers to the technology and procedure of protecting networks and devices from damage, unauthorized access, or attacks. Because data is now the core component of any organization, cybersecurity is critical for a country’s...
How to Set Up Laravel 8 on Your Android Phone
Hey, how are you doing? In this article, I’m going to show you how you can install Laravel 8 on your phone. To get the most out of this guide, you should have some knowledge of PHP and you should know what Laravel is. But if you don’t, don’t worry – I will explain the basics so you can get started. What Is Laravel? Laravel is a web application framework with expressive, elegant syntax. It’s built on PHP, which means that Laravel is PHP but it makes things easier to work with. It comes with lots of packages for various features, like authentication, so we don’t need to write authentication ourselves. To learn more about what Laravel can do, you can visit the site at laravel.com. Why I wrote this tutorial I created this tutorial because I want people interested in programming who don’t have a laptop or pc to be able to build things on their phones. My last post on freeCodeCamp made me realize that people are interested in learning how the tech works, so that’s why I’m making more guides like this. So let’s dive into it. In this tutorial I am going to show you how you can install composer.php and use it to set up Laravel 8 on your phone 🔥🔥. I am Precious Oladele, and I’m almost 19 this month 🥴. I’m from Nigeria and I will be taking you through this process. And if you’re wondering how I know so much about this, it’s because I also don’t have a laptop so I explore with my phone instead 😎.

To me, Robert Pirsig’s bestseller Zen and the Art of Motorcycle Maintenance (1974) was definitely one of the more engaging reads I’ve come across. The aim of this article is not to give a synopsis on the Metaphysics of Quality, but to distill some insights that might aid data scientists when getting discouraged with their project. Zen and the Art of Motorcycle Maintenance For those who have not read it — or those in need of a quick recap — the book interweaves the philosophical life journey of the author with the fabric of an All-American motorcycle road trip. It provides a thesis on the concept of quality, unifying the romantic and the classical perceptions of the world. As an illustration of those two viewpoints, the titular act of motorcycle maintenance serves as an extensive anecdote throughout the book. The romantic soul is primarily interested with how the motorcycle drives, looks and feels. A mechanical failure is nothing but a source of frustration. The classical soul, on the other hand, is concerned with the inner mechanisms of the machine, wants to know exactly what each part does. For them, a breakdown might actually pose an interesting challenge. It is not hard to see the analogies with programming and data science. When faced with a malfunctioning piece of software or nonsensible results, many users will throw up their hands in despair. It takes a certain fortitude and analytical mindset to dive into the underlying data sets or error messages. The classical soul is at work here. However, even one with a strictly classical view on the world is not immune...
Laravel Eloquent Power Joins Package | Laravel News
If you have some experience using databases, it is very likely you have used joins at least once in your career. Joins can be used for a bunch of different reasons, from selecting data from other tables to limiting the matches of your query. I’m going to give a few examples on this post, so, in order to contextualize the examples, imagine we have the following database/models structure. User -> hasMany -> Post Post -> hasMany -> Comment Post -> morphMany -> Image On Laravel, using eloquent, joining the posts table would look something like this: In case you want to join the posts and the comments table, your query would look something like this: This is fine and we can understand, but we can do better. We already have all these relationships defined in our models, but we are repeating some of the implementation details when we write the join statements. So, instead of doing this, wouldn’t be cool if you could just do the following? This is less code to read, and more importantly, easier code to read. It also hides any implementation details on how your relationships work. So, if your relationship changes, your joins will be automatically updated. Introducing the Eloquent Power Joins package We felt the way we did joins in our applications wasn’t really the “Laravel way”, so we decided to introduce some of the Laravel fine touch into the way we do joins. joinRelationship is a method introduced by the Eloquent Power Joins package. It works with any type of the existing Laravel relationships. The installation of the package is as simple...

The Best Google Chrome Extensions For Every WordPress Web Developer
Google Chrome wasn’t the first web browser to enter the arena, yet despite a growing number of competitors over the years, it continues to hold the title of most popular. Since arriving on the scene in 2008, Chrome steadily closed ranks, then easily surpassed the once-dominant Mozilla Firefox and Microsoft Internet Explorer (the latter of which had upwards of 90% market share in its heyday). Even diehard Foxophiles and Gate(s)keepers―currently retaining barely 5% of the browser market combined―have long since switched to the metallic maven. Whether surfing from a desktop or a mobile device, Chrome is definitively the most-used browser in pretty much any country. As a web developer, you want to be sure that what you’ve designed is able to adapt to any device or browser. Google Chrome, as the most used browser, should be at the top of that list. Aside from using Chrome as part of your browser testing, it’s also helpful in terms of the tools (or extensions) that were specifically created for web developers. To that end, we’ve put together a handy list of Chrome web developer extensions that we feel really pass the muster. Keep reading to find out what they are, or use the jump links below to go to any section. And off we go… Developers Paradise Aside from using Chrome as part of your browser testing, it’s also helpful in terms of the tools/extensions that were specifically created with Chrome web developers in mind. WordPress developers know how powerful the CMS is on its own, but you can make it even faster and more efficient directly from your Chrome browser...
Desktop Cyber Security – The Best Defense… is a Good Offense
Know Where you Stand and What Threats you Face I’ve talked about desktop tools and infrastructure solutions designed to block hacker intrusions and clean systems of virus and malware. We’ve reviewed testing and training users to make sure the human element is addressed to keep the bad actors out. We’ve looked at several ways to mitigate the risk and give you recovery and continuity. You may know IPDRR – Identify. Protect. Detect. Respond. Recover. These are the basic tenets of cyber security protocol. The first three are the keys to a proactive methodology – a good offense. Simply put, they are knowing the pieces of your network, deploying blocking tools to those pieces and setting up an alerting system that can detect threats – in real time. Know your networks The asset and inventory tools we use to track our knowledge of client systems are initially populated when we take on a new client. This is all part of Beringer’s tried-and-true onboarding process. That database is then updated as every change is made to the network, whether it be due to a project to upgrade infrastructure, a remediation for performance, modifications to local or cloud access, or security or any other change. Deploy Your Safety Net We use anti-virus and anti-malware tools in every case… An Endpoint/Managed Detection and Response (EDR/MDR) solution provides an additional underlying layer of managed detection and response. This way, we can defend against malicious, persistent footholds, ransomware and more – that are not readily apparent to the other cyber security tools above.. Add ThreatOps to The Arsenal The solutions above provide alerting to our...
Async processing of long-running tasks in ASP.NET Core | elmah.io
Async processing of long-running tasks in ASP.NET Core Written by Thomas Ardal, September 14, 2021 Sometimes, invoking an API endpoint needs to trigger a long-running task. Examples of this could be invoking an external and slow API or sending an email, which you don’t want the caller of your API to wait for. There are multiple ways of implementing this using a message broker, a fire and forget API request, or something completely third. In this post, I’ll show you how to implement async processing in ASP.NET Core, using a queue and the Background Worker feature. To understand how to process long-running tasks, let’s start by creating an example and making it sloooooow. Create a new ASP.NET Core application through Visual Studio, dotnet, or your preferred scaffolding engine. For this example, I have chosen the MVC template, but it could just as well be one of the other options. Next, in the HomeController.cs file, create a new method to simulate a call to a slow running task: For the demo, I’m waiting 10 seconds to simulate some work. The Task.Delay line would be replaced with some integration code in a real-life example. I have wrapped the code in information messages, which I can later inspect in Visual Studio or through the configured logger (maybe elmah.io?). Then, invoke the CallSlowApi method from the Index method: Let’s run the application and inspect the performance in Developer Tools: As expected, loading the frontpage takes just above 10 seconds (10 seconds for the Task.Delay and 30 milliseconds to load the page). Refactoring time! To process the message asynchronously, we’ll implement a background worker...
