How to safely delete records in massive tables on AWS using Laravel – Flare blog
When reviewing the contents of the database of Flare, we encountered a table with 1 billion records. Technically that isn’t a problem. Flare runs on Vapor and uses an Aurora database, so it can handle that scale. But of course, there’s a cost for storing that many records. We dove in and concluded that we could safely delete about 900 million records. They all were created before a specific date. Attempt 1: running a single delete query # A first naive approach would be to run a simple delete query. Performing a delete query like this on a small table will probably work. But when your table contains a billion items, it will likely cause problems. In most cases, a database will try to perform all queries atomically, so no other queries see intermediary results. When a deletion query using a where clause starts, it will lock that table. All other queries that are run against the table will have to wait. Because of the massive size of the table, the deletion query would probably run for hours. The lock would be in place for hours, essentially halting the entire app. So, just running a single query to clean up the table isn’t a good idea. Attempt 2: using a limit # To make the query complete faster, you can add a limit clause. Because the query completes faster, the table lock will be released much faster as well. Other queries wont be halted as long. Here’s an artisan command that performs that query. In the code above, only the 1000 first selected are deleted. Our tables contain many...

Utah Hosts Defense Department Cyber Security Exercise
CAMP WILLIAMS, Utah – Hundreds of military and civilian cyber defense specialists converged on Utah Tuesday as the largest unclassified cyber defense exercise began at Camp Williams. As we learned earlier this year with the Colonial Pipeline and the JBS meatpacking plant computer attacks, cybersecurity is an ever-growing concern for the public. About 800 people from around the country came to Utah for Cyber Shield 2021. It’s a major event for Camp Williams. “What we are doing here at Cyber Shield gives our soldiers real-world experience,” said Lt. Col. Brad Rhodes. The Army National Guard has stepped up its cybersecurity training. Hundreds of military members from across the U.S. are training on defense-focused tactical exercises. “Depending on which open-source material you read, China has 50 – 100,000 cyber operators. They’re building capacity to attack and do incursions and properties around the world,” Rhodes said. “So, it is very important to understand the nation-state actors out there are building these capacities and it’s why we need to build these capacities.” Rhodes has decades of experience in the military. He said the importance of cyber security has grown to the top of the list of priorities. “Inside the military itself, across the department of defense, we are actually a pretty small cadre. Having been in Cyber Com and working some of those missions out there, I will argue we are probably some of the most capable and talented cyber force,” he said. The Cyber Shield training brought in people from cyber departments with large companies like Boeing, Microsoft and Utah’s Pluralsight. “We look at what we are doing here for simulation. We start at website defacement, then...
Implementing Nanoservices in ASP.NET Core
Application architectures have evolved very quickly during the latest few years. The classic monolithic architecture has been broken down into a collection of microservices to support a more dynamic development and deployment infrastructure. However, albeit its popularity, there are certain downsides to using a microservice architecture. Recently, a more granular breakdown of a distributed application components is becoming popular: nanoservices. Nanoservices aren’t a replacement for microservices but are adept at addressing some of their shortcomings, and they can provide better isolation and granularity. This article will introduce the nanoservice architecture and show how to create them with ASP.NET and Azure Functions. From Monolithic to Nanoservice Architecture A monolithic architecture comprises a collection of components that are built, deployed, scaled, and maintained as a single unit. Albeit the simplicity, it is extremely difficult to change, scale or maintain such applications. A monolithic application typically uses a homogenous technology platform. Building a monolith with heterogeneous technologies is extremely difficult. Over a while, a monolith can become highly complex to handle: operational agility, scalability, and maintainability can become a challenge. Microservice architecture evolved to address the shortcomings of monolithic architectures over the past few years. Microservices adoption has been on the rise primarily because of the quest for improved scalability, flexibility, and performance. What is microservice architecture? Microservice architecture is a service-oriented architecture (SOA) variant that builds an application comprising lightweight, loosely coupled, modular services. These services can execute on a wide variety of platforms and are independently developed, tested, deployed, and managed. Microservice architecture is easier to maintain, scale, and test because they are smaller and more focused than their predecessors....

For AngularJs, the most powerful component continues to be directives. Let’s understand what directives mean here. It is nothing but an extended version of the HTML attributes with the prefix ng added to it. With the ng-app, you can initialize the AngularJS application. Similarly, using the ng-init directive you can initialize the application data. In this article, we will talk mostly about the custom directives, and how you can master these directives thus making your AngularJS based application worthy for users. Remember, your aim is to offer a good application that can empower the users. Simple Directives If you want to create a widget that would arrange the different profile details that you are planning to display on your application, then you should ideally use simple directives. It offers a creative view of the elements. Here is an example of a widget created to view the book details on an e-commerce application angular.module('masteringAngularJsDirectives', []) .directive('book', function() { return { restrict: 'E', scope: { data: '=' }, templateUrl: 'templates/book-widget.html' } }) With this, you have created a directive first, which has been named book for this example. This directive returns an object. Restrict will define the directive type- attribute, class, element or comment. Scope gives you an idea of the directive’s scope. With templateURL, you can view content for render specific content. This will remove the complications associated with HTML Isolated Scope When you talk of directives, you will see an underlying scope alongside each directive. Data binding is an important element of directive declaration. For this example, we will consider implementing the basket portion of the e-commerce application. Here’s...

UK government needs to boost cyber security of its food supply chains
Following last month’s ransomware attack against the world’s largest meatpacker JBS, experts in the UK are also taking closure look at how vulnerable the UK’s food supply chains are to cyber attacks. A leading food expert has warned that the Britain’s food supply is highly vulnerable to attacks from threat actors, and warns that the government needs to put emphasis on domestic production to boost food security in the country. “If anyone wanted to really damage the British food system, they could just take out the satellites,” Tim Lang, professor of food policy at City, University of London, told . “Our ‘just-in-time’ system is entirely dependent on computerised logistics. When you pay for your food at the checkout, the computer isn’t just adding up the bill, it’s reordering the stock.” Last month’s attack on JBS led to increased pressure on a food-supply chain that is already under strain due to high transportation costs, labour shortages and production constraints. The attack forced the company to shut down several plants in the US and Australia, impacting beef markets. While JBS downplayed the impact, it admitted that it had paid $11 million in ransom to the hackers. In recent years, experts have drawn attention to the large number of food companies still using legacy computer systems as well as outdated software that are vulnerable to cyber attacks. They advise that the government need to enforce cyber security standards in the food industry in the same way it enforces food safety standards. Lang’s warning comes as the UK government is due to publish the second part of its national food strategy. The first...
A Fresh Look From The Inside: Interview With Andrew Chang, Web Developer – Mobile App Development and Web Development – Vancouver BC
An interview with one of our most recent hires, Andrew Chang. Tell us a little bit about yourself. I was born and grew up in Vancouver, BC. My favourite past time has always been playing video games as a kid, and that hasn’t changed much. I first went to UBC to study Computer Science and then BCIT for a different program. How did you select Computer Science as your career path? I think I chose computer science as more of an educational path than a career path. I was always interested in computers so I knew I wanted to pursue a path related to computers, but it didn’t have to be specifically computer science. If I hadn’t gotten accepted into computer science, I would’ve chosen a different program or a different school. What attracted you to work at 14 Oranges? What attracted me was that 14 Oranges is a local and well-established company for many years, so I was interested in learning the skills and knowledge from the experienced designers and developers here. In addition, 14 Oranges is involved in areas that I was interested in such as web development. I was also looking for a remote internship and 14 Oranges is flexible and offers remote work from home, which is really great especially when there’s a global pandemic. You were hired during the pandemic. What are some of the challenges of working in a company where you haven’t met anyone in person? Not sure. None that I can think of, maybe because I’m lacking in experiences of working at other tech companies. What do you look forward to...
Refactoring to Laravel 8 Class Model Factories | C.S. Rhymes
Published: Jul 20, 2021 by C.S. Rhymes Laravel 8 introduced new class based model factories and if you have an existing project you can use the legacy factories package to keep using the old factories. I have tended to keep the factories as they were and continue development, but after working on a fresh Laravel 8 project and using the new class based syntax I decided to go back and update the factories in the older Laravel apps. This article explains how I went about refactoring the factories to classes. In this scenario we have a Laravel app that allows you to create a post. The post has a title, content, author and is either published or not published. Original Factory Here is the PostFactory in the previous format. It defines the default state, with the publish value set to false. It has a state called published where the publish value is set to true. // database/factories/PostFactory.php <?php /** @var \Illuminate\Database\Eloquent\Factory $factory */ use App\Post; use Faker\Generator as Faker; $factory->define(Post::class, function (Faker $faker) { return [ 'title' => $faker->words(3, true), 'content' => $faker->text, 'author_id' => factory(User::class), 'publish' => false, ]; }); $factory->state(Post::class, 'published', function (Faker $faker) { return [ 'publish' => true, ] }); Here is a very basic example showing the factory being used in a test, using the factory() helper method. The second test in the example has the published state applied to it. // tests/Unit/PostTest.php <?php namespace Tests\Unit; use App\Post; use Tests\TestCase; class PostTest extends TestCase { public function test_post_is_not_published() { $post = factory(Post::class)->make(); $this->assertFalse($post->published); } public function test_published_post_is_published() { $post = factory(Post::class)->state('published')->make(); $this->assertTrue($post->published); } }...

Cyber Security Today, Week in Review for Friday, July 9, 2021 | IT World Canada News
Welcome to Cyber Security Today. This is the Week in Review edition for the week ending Friday July 9th. From my studio in Toronto, I’m Howard Solomon, contributing writer on cybersecurity for ITWorldCanada.com. With me today to discuss events is Dinah Davis, Canadian-based vice-president of research and development at Arctic Wolf. We’ll chat in a few minutes. But first a look back at some of the news from the past seven days: The big news, of course, was the huge ransomware attack that spread to some 1,500 companies using or customer of managed service providers using the Kaseya VSA remote IT monitoring product. This attack raises a lot of questions about the readiness of organizations to face cyber attacks, and whether this attack could have been worse. Dinah and I will tackle these and other questions. Microsoft has created patches for a security vulnerability in Windows print spooler called PrintNightmare, which allows an attacker to infiltrate networks through a print server. Administrators are urged to install the patch immediately, although there are reports it doesn’t completely close the hole. Dinah and I will talk about this. Separately, Microsoft urged Windows administrators to update PowerShell to close a serious vulnerability. Police in Morocco arrested a veteran cybercriminal who allegedly went by the name Dr. Hex and attacked or helped attack French telecom companies, banks and corporations. He is believed to have created and sold phishing and credit card theft kits. The investigation was the joint work of authorities in Morocco, the Interpol police co-operative and a Singapore-based threat intelligence company called Group-IB. U.S.-based insurance brokerage Arthur J. Gallagher has now acknowledged...
Web Designer vs Web Developer | Course Report
By Jess Feldman Last Updated July 22, 2021 So much goes into building a successful website, and it requires the efforts of both web designers and web developers. But what exactly are the differences between these two tech roles? We dive into the typical responsibilities and average salaries of today’s web designers and web developers, plus the languages and tools that web developers and web designers rely on. Plus, find out how to learn web development and web design, whether you’re upskilling or making a career pivot! What is Web Design? A lot of work goes into building a website and how a website looks is one of the most important aspects. Web designers are responsible for the visual aspects of a website. Design is more than just deciding what looks “good!” It’s a web designer’s job to ensure the product is designed well while also being functional. For instance, web designers understand that some colors make it harder to focus; or that fonts can make a difference in readability; or that cluttered layouts can be confusing. What types of projects do Web Designers work on? A web designer’s responsibilities can vary widely depending on where they work. At minimum, web designers will be responsible for deciding: Typically, web designers will be creating a finished product for an already existing framework. You may have noticed that many modern websites have a similar layout and feel. Design theory is a subtle yet important aspect of anything visual. It’s easy to ignore when designers do their job correctly, but a poorly designed website tends to stand out. Building a website is...
React Native vs. Ionic: What Cross-Platform Framework is the Best? – Flatlogic Blog
We have decided to try our best in putting to rest the question “Which one is a better framework: React Native or Ionic?” And to do that, first and foremost we need to take a bit deeper look into each one of them. So, without further ado, let’s start with React Native. A brief guide into React Native So, what is, in broad terms, React Native? React Native is an open-source mobile application framework created by Facebook, Inc. Its usability lies in the sphere of app development for such operational systems and platforms as Android, Android TV, iOS, macOS, tvOS, Web, Windows and UWP. Basically, it is a framework that allows you to build different kinds of apps using nothing more than the ever-universal programming language, known as JavaScript. And, as it is based on the same design as React, it also makes it possible to compose a rich mobile UI from declarative components by using the same fundamental UI building blocks as regular iOS and Android apps. The end result, if built correctly, is hardly distinguishable from any apps built with Java or Objective-C. Now, let’s take a closer look on the advantages that React Native has (not comparing it to Ionic in any way for now). In Flatlogic we create web & mobile application templates built with React, Vue, Angular and React Native to help you develop web & mobile apps faster. Go and check out yourself!See our themes! React Native saves time and money The justification for this advantage is the fact that, by having its code as cross-platform as it can be, React Native allows...
80% of Organizations Overshoot Their Big Data Cloud Budgets. Here’s Why. | Pepperdata
Full or partial cloud migration has been all the rage for a few years. The worldwide public cloud services market is predicted to grow 17% in 2020, to a total of $266.4 billion. According to Gartner, 35% of CIOs are decreasing their investment in their infrastructure and data center, while 33% are increasing their investment in cloud services or solutions. But there’s a catch. Gartner also predicts that: “through 2020, 80% of organizations will overshoot their cloud IaaS budgets due to a lack of cost optimization approaches.” When big data cloud migration is still in its early stages, it all seems easy-going. Operating a data center in the cloud is always cheaper than on dedicated on-premises servers. But, eventually, when enterprise IT organizations receive their first few cloud bills, they are often shocked and puzzled. Compared to their legacy stance, they suddenly cannot understand what they are spending on or why. Big data cloud invoices can add up to hundreds of thousands more dollars than expected. When Bain & Company asked more than 350 IT decision-makers what aspects of their cloud deployment had been the most disappointing, the top complaint was that the cost of ownership had either remained the same or increased. Why the lack of cost optimization approaches? Because IT operations are in a visibility crisis: In order to optimize costs, IT operations require full-stack visibility to optimize application performance, support SLAs, uncover infrastructure inefficiencies, and minimize MTTR (mean time to repair). What makes this a daunting task, however, is the sheer size of modern big data clusters, running to thousands of nodes. Add to that the...
How to use Database Sharding and Scale an ASP.NET Core Microservice Architecture
How to use Database Sharding and Scale an ASP.NET Core Microservice Architecture Load Balance a C# ASP.NET Core Service and Use MySql App-Layer Sharding. Shows the Concepts, Which Also Apply to MongoDB, etc. One of the big advantages of microservices is, that they can be scaled independently. This article shows the benefits and challenges of scaling one microservice and its database. You will create a working example application and manually implement application-layer sharding. It shows how to choose a shard key based on the use-cases and data model. This helps to apply the same principles to DBMS with integrated scaling like MongoDB, etc. Further reading: by and by This is the first of two parts. You will implement the microservice and use a sharded DB. In the second part, you will scale and run multiple container instances of the microservice and databases. You will use docker compose and a load balancer. Finally, you run JMeter load tests to see how the application scales when using a different number of instances. 1. Usecases and Datamodell The example application consists of a user and a post microservice. They communicate via messages: See also my previous article The User microservice handles adding and modifying users. The Post microservices handles viewing and adding posts. There is far more interaction with the Post microservice. So when the load to the app increases the Post microservice will be the first microservice that needs to scale. The name of the author is part of the PostService bounded context and therefore the Post microservice. Adding and modifying authors is done in the User microservice. The User microservice sends events when a...
