Identity and Access Management Best Practices

Aggregated on: 2023-09-08 22:16:42

Identity and access management (IAM) is fundamental to modern cybersecurity and operational efficiency. It allows organizations to secure their data, comply with regulations, improve user productivity, and build a strong foundation for trustworthy and successful business operations. A robust IAM solution also aids in protecting APIs and applications that are built to accelerate the digitalization of services, enabling growth and customer loyalty. This article will examine some of the best practices IT practitioners should follow when working with IAM systems. Even though some of the suggestions are not necessarily new, they still need to be widely adopted to be effective and should be considered as soon as possible. 1. Zero-Trust on Identity As mentioned in the introduction, APIs are critical in accelerating enterprise digital transformation. However, building and managing multiple APIs comes with various security risks since API calls transfer sensitive data that cyber criminals can easily access if the API endpoints are not strongly secured. A zero-trust approach, where no device or service is trusted, needs a strong focus on identity. By using token-based OAuth solutions, identity credentials can flow through services in a secure and integrity-protected way. This enables all parts of a system to properly authorize requests, trusting only the data coming directly from the IAM system.

Running Ansible From Windows Using Virtualization

Aggregated on: 2023-09-06 21:01:41

Recently, I had to use Ansible to implement infrastructure as code. Initially, I used Windows Subsystem for Linux (WSL) to run the Ansible playbooks. The advantage of WSL is that it gives one a Linux shell on a Windows machine without any further ado. However, I found that WSL has this tendency to go haywire and use system resources such as CPU and RAM to the max. Although it did not lead to performance degradation in other running processes or applications, it did cause my notebook with 40GB of RAM to become very hot and use excessive electricity. Once WSL reaches this state, all new requests for a WSL prompt hang. Since the virtual memory processes used to enable WSL are protected and cannot be killed or restarted, the only recourse is a good old Windows reboot. I considered installing Linux on an old notebook and running the Ansible playbooks from there. Unfortunately, the target servers are behind a VPN, so the Linux machine would have to receive special software to allow it to join the VPN. In order to sidestep corporate hassle, I went with running Linux virtually on Hyper-V, the native Windows 10 Hypervisor. The steps I followed will be documented next.

Solving Unique Search Requirements Using TreeMap Data Structure

Aggregated on: 2023-09-06 20:46:41

TreeMap is a Java collection that structures the data in the form of an ordered key and their respective values. It has been available since JDK 1.2. Internally, TreeMap uses a red-black tree to structure the data, which is a self-balancing binary tree. The keys in TreeMap are unique identifiers, and by default, TreeMap arranges the data in a natural ordering of keys. For the integer keys, it is stored in the ascending order of the keys, and for the String key, the data will be stored in the alphabetic order. We can always override the default ordering of data and can inject custom sorting by using a comparator during the TreeMap creation to sort in any defined manner as per the logic provided in the comparator. We will discuss in detail a few of the custom hybrid sorting approaches along with some code examples in this article.

Aggregated on: 2023-09-06 20:01:41

As a computer graphics and programming languages geek, I am delighted to have found myself working on several GPU compilers in the past two years. This began in 2021 when I started to contribute to taichi, a Python library that compiles Python functions into GPU kernels in CUDA, Metal, or Vulkan. Later on, I joined Meta and started working on SparkSL, which is the shader language that powers cross-platform GPU programming for AR effects on Instagram and Facebook. Aside from personal pleasure, I have always believed, or at least hoped, that these frameworks are actually quite useful; they make GPU programming more accessible to non-experts, empowering people to create fascinating graphics content without having to master complex GPU concepts. In my latest installment of compilers, I turned my eyes to WebGPU -- the next-generation graphics API for the web. WebGPU promises to bring high-performance graphics via low CPU overhead and explicit GPU control, aligning with the trend started by Vulkan and D3D12 some seven years ago. Just like Vulkan, the performance benefits of WebGPU come at the cost of a steep learning curve. Although I'm confident that this won't stop talented programmers around the world from building amazing content with WebGPU, I wanted to provide people with a way to play with WebGPU without having to confront its complexity. This is how taichi.js came to be.

Low Latency? In computing, latency is defined as the length of time to perform some task. This could be the time it takes to respond to an interrupt from hardware or the time it takes for a message sent by one component to be available to its recipient. In many cases, latency is not seen as a primary non-functional concern when designing an application, even when considering performance. Most of the time, after all, computers seem to do their work at speeds that are well beyond human perception, typically using scales of milliseconds, microseconds, or even nanoseconds. The focus is often more on throughput - a measure of how many events can be handled within a given time period. However, basic arithmetic tells us that if a service can handle an event with low latency (for example, microseconds), then it will be able to handle far more events within a given time period, say 1 second, than a service with millisecond event handling latency. This can allow us to avoid, in many cases, the need to implement horizontal scaling (starting new instances) of a service, a strategy that introduces significant complexity into an application and may not even be possible for some workloads.

Business analytics is the practice of using data and statistical analysis to help businesses make better decisions. This can involve analyzing data to identify trends, patterns, and relationships and using that information to help businesses make better decisions about their operations, marketing, and strategy. The value of Business Analytics is clear. Data-driven decisions can help businesses measure their performance, understand their customers, and, most importantly, drive growth. With an increasing number of businesses relying on APIs as their de facto digital supply chain, there is even more data out there for enterprises to measure and analyze. Yet many are missing out by not making the most of their API business analytics or even using them at all.

'Expected Declaration or Statement at End of Input' in C Solved

Aggregated on: 2023-09-06 16:16:41

Programming in C requires careful attention to detail, as even small syntax errors can cause unexpected problems in your code. One common error message that developers may encounter when writing C code is "Expected declaration or statement at the end of input." This error message can be frustrating to deal with, but fortunately, it is usually straightforward to diagnose and fix. In this article, you will learn how to identify where the problem is, how to deal with it, and how to avoid it. Identify the Problem When the "Expected declaration or statement at the end of input" error occurs, it means that the compiler has reached the end of the file or function without finding a complete statement or declaration. In other words, the compiler is expecting to find some additional code but instead has reached the end of the program without finding it.

How StackOverflow Is Adapting in the Face of Generative AI

Aggregated on: 2023-09-06 15:46:41

StackOverflow, the most commonly used platform by software developers for programming support, has been through a rough ride lately. Despite an impressive 69% of questions answered, StackOverflow’s traffic has been in decline. Similarweb’s data shows that their traffic dropped 14% year over year (StackOverflow says it’s closer to 5%). Nevertheless, the trend is downward and is explained primarily by the emergence of AI coding products like ChatGPT and GitHub Copilot. These products have meaningful code-writing capabilities and are, therefore, able to provide programming support, at least partly as good as StackOverflow does. Ironically, several of the large language models (LLMs) behind these AI products were trained using scraped StackOverflow data. The company has gotten pretty harsh media coverage with these developments. Business Insider, in their article Death by LLM, wrote:
