Aggregated on: 2021-10-16 10:35:21

Kubernetes in general is a boon for SREs. By making it easy to manage microservices-based apps at scale, Kubernetes helps SRE teams achieve reliability goals for complex, cloud-native environments. But if you know anything about Kubernetes, you know that there are a number of different Kubernetes distributions and services available, each with different strengths and weaknesses.

How to Run Playwright Tests Sequentially in Same Browser Context

Aggregated on: 2021-10-16 09:50:21

The Playwright is a new automation framework by Microsoft. The Playwright framework is distributed under MIT Open Source License. Playwright supports various programming languages such as Java, JavaScript, TypeScript, .Net, etc. Playwright Executes Each Scenario in Its Own New Browser Context If you have worked with the Playwright framework you might have observed that if you write multiple tests inside the describe function, it gets executed one after another but each test runs in a separate browser context. That means that if you have performed a login in test1() it doesn't preserve those in test2(). The reason is that each time playwright executes the test, it creates a new context and executes the test. This feature also allows you to write independent tests and you can execute them parallelly with less execution time.

Getting a Wildcard SSL Certificate for Your Website at No Cost

Aggregated on: 2021-10-16 02:55:26

When you work for any software deployment project, you deploy code in multiple environments and test it. You test the site with HTTP but not in HTTPS. Why? Because you need an additional certificate for it. Getting a certificate for a lower environment could be difficult due to the costing factors, but there is a way by which you can get a wildcard certificate and configure it with your website. You can implement a PKI solution by using the AD CS Windows Server role.

6 Ways To Ruin Your Logging

Aggregated on: 2021-10-16 02:55:26

I’m knee-deep in some log refactoring on my current project, which is something that I’ve done now on several projects. This is one of my favorite ways to become familiar with a new codebase since it typically touches all of the code. As I do this on new projects, I’m consistently faced with many of the same frustrations, which I have decided to catalog here. Most projects I see make at least several of these mistakes, some make all of them. But since misery loves company, I’ll share these frustrations with you, so that you can repeat them and join me in commiserating–or avoid them, if you so choose.

Two Key Focuses (And a Checklist) For New Engineering Managers

Aggregated on: 2021-10-16 02:55:26

There is very little formal guidance for new engineering managers. When I first moved from an individual contributor (IC) to an engineering manager (EM), I found myself struggling to find training resources. I want to change that - and I hope this article will serve as a small start in that direction. As an engineering leader at Mark43, I do a lot of mentorship and coaching for engineers who aspire to move to engineering management and early-tenure engineering leaders. Here are a couple of initial focus areas that a first time EM can build upon.

Increase Your DevOps Productivity Using Infrastructure as Low Code

Aggregated on: 2021-10-16 02:55:26

As an individual developer or as a part of a wider software development or IT team, you will find that time is rarely on your side, with many competing priorities throughout the working week. This naturally focuses you to look for ways to increase your productivity through the use of technology and tools to help you achieve more in less time. Throughout this blog post, we’re going to look at DevOps productivity and compare traditional tools with infrastructure as low code tools. Automate Software Development Tasks With DevOps Tooling Everyone has heard of DevOps, yet many people struggle to understand exactly what DevOps is. Fundamentally DevOps is a perfect mixture of the philosophy of DevOps along with daily practices and supporting technology tools to enable you to deliver value through technology rapidly to your customers.

Programming BS: Checked Exceptions

Aggregated on: 2021-10-16 02:55:26

The Problem I have always hated being forced to catch an exception, largely because: Remember that code you wrote that brings the database backup, adds disk space or memory, grants the correct file privileges as root? Neither do I. If a real problem occurs that is beyond the control of your code, then by definition, you cannot change the outcome. So what's the point of forcing you to handle it? Just because something is a problem for you, doesn't mean it's a problem for me. EG, in Java JNI (basically a key/value store), if you look up a value for a given key, but the key does not exist, it throws an exception. It seems the designers of JNI assumed it is the only source of information for a given value. What if it isn't? Since there is nothing you can really do in response to an exception, they wind up being re-thrown up to the top, where a web service returns an HTTP 500 code, a GUI displays a "there's a problem we can't fix" dialog to the user. If an interface method does not declare any checked exception type, the implementation cannot throw any checked exceptions. But what if the implementation has to make calls that throw checked exceptions? Sometimes you're forced to use exception handling as an if/then statement Sometimes you need to have nested try/catch blocks, which can be hard to reason about and are invariably not unit tested for each catch statement. Strategies If you look at Java code as an example, people use various strategies to try to deal with checked exceptions, such as:

Fantastic ML Pipelines and Tips for Building Them

Aggregated on: 2021-10-16 02:55:26

A machine learning (ML) pipeline is an automated workflow that operates by enabling the transformation of data, funneling them through a model, and evaluating the outcome. In order to cater to these requirements, an ML pipeline consists of several steps such as training a model, model evaluation, visualization after post-processing, etc. Each step is crucial towards the success of the whole pipeline, not only for the short-term but also in the long run. In order to ensure the sustainability of a pipeline in the longer run, ML engineers and organizations need to account for several ML-specific risk factors in the system design. The authors from Google pinpoint risk factors such as boundary erosion, entanglement, hidden feedback loops, undeclared consumers, data dependencies, configuration issues, changes in the external world, and a variety of system-level anti-patterns [1]. In this article, we will be diving deep into the root causes of some of these risk factors. Figure 1: Automated pipeline (source : 123.rf) 1. Boundary Erosion If you are given an ML pipeline and if your data team approaches you with a change in the input feature such as increase/reduction in dimension, would you be able to ensure that it won't affect the entire pipeline? Mostly the answer would be no.

Exploring PGBouncer auth_type(s) With CockroachDB

Aggregated on: 2021-10-16 02:55:26

PGBouncer is a lightweight connections pooler for PostgreSQL. There are instances where PGBouncer can be used with CockroachDB to offset the high costs of having many active connections, segregation of responsibilities (i.e. business analysts are segregated from the mission-critical users) serverless applications needing pooling mechanisms. PGBouncer comes standard with various types of authentication mechanisms, and we're going to explore a few compatible with CockroachDB. We already explored trust and cert in my previous article, feel free to review that if you need a refresher. Previous Articles Using PGBouncer with CockroachDB Using PGBouncer with Cockroach Cloud Free Tier Exploring PGBouncer auth_type(s) with CockroachDB Motivation CockroachDB offers a rich gamut of authentication mechanisms. The most widely accepted by engineering is cert-based authentication. We also support gss, but within the context of PGBouncer, it is not supported. For today's session, I will cover the remaining supported types in PGBouncer and how they translate to CockroachDB. For a brief overview of all available PG and CockroachDB auth methods, I'd like to direct you to an in-depth blog by one of our engineers. Also, I must mention that everything stated in this article may be dated by the time you read this as CockroachDB is under active development and we may support more auth_type(s) later.

Data as an Asset — Recipe for Success

Aggregated on: 2021-10-16 02:55:26

The growth in the number of connected devices, new regulatory compliances, the promise of 5G, and evolving methods of using and analyzing data have ushered in a new age driven by insights gained from connecting customer, strategic, and operational data. Businesses are transitioning into becoming more data-centric now, calling for more advanced data management and analytic systems. Data underpins the success of organizations in mining both physical assets and digital business opportunities — improving accuracy, increasing efficiency, and augmenting the ability of the workforce to deliver excellent value. Data, essentially, is the lifeblood of any organization, and hence, its accessibility, monitoring, and availability become an essential factor for business agility.

Building Our E-Commerce Platform With Serverless FaaS

Aggregated on: 2021-10-16 02:55:26

With so many 'something-as-a-service' options at our disposal for infrastructure, in 2017 we opted for function-as-a-service (FaaS) to build our platform of e-commerce services. Our mission was, and remains, to build for e-commerce services what AWS built for web services, or what we call the commerce fabric of the internet. Building with FaaS and only paying for function execution time rather than constantly running servers (i.e. serverless) allowed us to serve customers early on without incurring high infrastructure costs. These customers were large, household names and referrals from our founding team who had transformed digital at Staples. Part of this transformation involved moving from the monolithic e-commerce platform IBM Websphere to a service-oriented architecture with open-source and custom-built software.

Of Low-Code, Digital Trust, and Staying Ahead of the Risk Curve

Aggregated on: 2021-10-16 02:55:26

It's easy to throw shade on risk like it’s a bad thing. But all innovation involves risk. Which isn’t necessarily bad. Not if the consequences of being wrong about it don’t pose an existential threat. But businesses everywhere are struggling to cope with doomsday scenarios such as climate change, cyber smash-and-grabs, the global COVID-19 crisis, and more. Looking ahead, risk trends will continue to evolve as digital transformation accelerates, as the remote work trend mainstreams, and as enterprise spending on the internet of things tops $1 trillion by 2023. For context, overall IT spending is expected to surpass the $4 trillion mark in 2021, up 8.6% from 2020 according to analyst firm Gartner. But here’s the kicker: just 22% of CEOs believe they have a risk-management playbook to sustain the resiliency and long-term success of their business.

Managing Docker Apps With Kubernetes Ingress Controller

Aggregated on: 2021-10-16 02:55:26

Think back to when your development team made the switch to Dockerized containers. What was once an application requiring multiple services on virtual machines transitioned to an application consisting of multiple, tidy Docker containers. While the result was a streamlined system, the transition likely was daunting. Now, it’s time for another transformational leap: moving from a single set of containers to a highly available, orchestrated deployment of replica sets using Kubernetes. This may seem like a massive transformation, but you can reduce the bumps in the road by using an open-source Ingress Controller to simplify your task and provide plugins that you can customize based on your need.

How to Choose a Low-Code Integration Platform

Aggregated on: 2021-10-16 02:55:26

With the rapid and accelerated enthusiasm towards digital transformation initiatives, iPaaS solutions have become increasingly popular. iPaaS stands for Integration Platform as a Service and facilitates developing, deploying, executing, managing, and monitoring integration processes connecting multiple endpoints. With an iPaaS solution, external developers are not required for a company’s digital transformation efforts. Now, every company must become a software company. Therefore, everyone in the business must become a developer, and developers could exist in different lines of business, apart from the full-time developers in the central IT team. While the central IT team would continue to have full-time developers playing their role as integration specialists, other lines of business would have other integration personas such as ad hoc integrators and citizen developers.

Connecting to Presto With Superset

Aggregated on: 2021-10-16 02:55:26

TL;DR Superset refers to a connection to a distinct data source as a database. A single Presto cluster can connect to multiple data sources by configuring a Presto catalog for each desired data source. Hence, to make a Superset database connection to a particular data source through Presto, you must specify the Presto cluster and catalog in the SQLAlchemy URI as follows: presto://<presto-username>:<presto-password>@<presto-coordinator-url>:<http-server-port>/<catalog>. Superset and SQLAlchemy Superset is built as a Python Flask web application and leverages SQLAlchemy, a Python SQL toolkit, to provide a consistent abstraction layer to relational data sources. Superset uses a consistent SQLAlchemy URI as a connection string for a defined Superset database. The schema for the URI is as follows: dialect+driver://username:password@host:port/database. We will deconstruct the dialect, driver, and database in the following sections.

Aggregated on: 2021-10-16 02:55:26

MySQL is an open-source and one of the most widely used relational database management systems. Setting up a separate MySQL backup server is essential in the event of failure, as the backup server contains everything necessary for a successful recovery. Replication features in MySQL allow you to maintain multiple copies of MySQL data. All data in the master server will be synced to the slave server automatically. If your master server fails, you can promote a Slave to a Master for commit operations.

AWS Terraform Snitcher

Snitch (chivato in Spanish, “dedo-duro” in slang Portuguese), if you usually watch CNN, mainly political subjects, that’s a word that you probably hear a lot. The dictionary meaning is: “to secretly tell someone in authority that someone else has done something bad, often in order to cause trouble“. Ok, it sounds too strong maybe for our case, but what we want is a kind of a similar thing: catch (and who caused) the Drifts in Terraform state. Terraform Drifts Terraform Drift is when the actual state of your infrastructure does not equal the state defined by your configuration (Infrastructure-as-Code), then - they differ already.

The world's least popular programming language

Aggregated on: 2021-10-16 02:55:26

A software engineer looking to learn something new will typically first check how many available jobs there are related to the subject at hand, simply to make sure he or she is valuable for future employers - And we all know that the most popular programming languages includes JavaScript, Java, C#, Python and TypeScript. However, what is the least popular programming language, still in actual use, and why should you even care? Ignoring the funny prototype OOP parts of JavaScript, all of the above programming languages are more or less copies of each other, without much difference semantically. Sure, there are a few noteworthy exceptions, such as SQL and F#, but almost all programming languages at the top of the popularity index are more or less rip offs, copying and pasting features from each other. This creates a problem for you individually, and also for the world at large, which I refer to as local evolutionary optimums. The problem is best explained as follows ...

Introduction Watching the current tech trends are crucial, especially for large web projects owners who wish to outrun the competition. Deploying a simplified technology stack using new web development frameworks can lead to shorter development times and improved outcomes. Here are some ideas. Trend 1: Optimize Processes Developers want easy access to tools and a consistent style as well as accessibility recommendations, but each member of the team has different needs, resulting in a complex and dynamic development scenario. However, design systems are a simple and effective approach to the development process. The system caters to each team member’s needs, allowing them to focus on their task by providing access to component libraries and design patterns. Similar to older corporate design strategies but updated to include code-written guidance under version control, design systems ensure consistent digital products while creating an easy-to-maintain and unambiguous collection.

When asked about the best tools to automate infrastructure provisioning, two prevalent names come to mind: Terraform and AWS CloudFormation. This blog discusses the different aspects of Terraform vs CloudFormation in detail.

Super DRY code

Aggregated on: 2021-10-16 02:55:26

DRY means "Don't Repeat Yourself" and is arguably one of the most important design principles as you create code, regardless of what language you use. The reasons are simple; Because every time you repeat code, you have to modify multiple places if you need to change your logic. Hence, if you don't create DRY code, you get bloated software, repeating the same constructs, to the point where it becomes impossible to maintain. Hence, the very definition of DRY is that your code is reusable, implying you can arguably quantify how DRY your code is, by asking yourself how reusable your code is. OOP however has one fundamental flaw which makes it ridiculously difficult to create DRY code, which is best explained by the following famous quote about reuse in OOP... You want the banana, but you get a monkey, holding a banana, in the rain forest!

Securing Democratic Elections using cryptography, is actually very easy. In fact, what I am describing in this article, is really nothing but "blockchain for Democracy". But since we're all coders here, let me start with some simple pseudo code. Plain Text xxxxxxxxxx 1 1 openQueueSempahore 2 if (firstVote) 3 oldHash = hash(subject + body) 4 else 5 oldHash = previousVoteHash 6 newHash = hash(oldHash + username + voteValue) 7 insertVote(username, voteValue, newHash) 8 The whole idea with the above pseudo code, is that it results in a "chain of votes", where each individual vote, is based upon its previous vote's hash value. Then the first vote, is based upon the hash value of the subject and its content.

MSTest Tutorial: Environment Setup For Selenium Testing

Aggregated on: 2020-06-26 19:10:03

MSTest is a popular open-source test framework that is shipped along with the Visual Studio IDE. It is also referred to as Visual Studio Unit Testing Framework; however, MSTest is more synonymous within the developer community. As the MSTest framework comes pre-bundled with Visual Studio, many developers prefer MSTest over other C# frameworks such as NUnit, xUnit.net, etc. for Selenium test automation. The latest version of MSTest is MSTest V2, it is a major overhaul over its predecessor. The earlier version of MSTest i.e. MSTest V1 was not open-source and lacked many good features (particularly parallel test execution) which were supported by other Selenium C# testing frameworks.

Why Camel K?

Aggregated on: 2020-06-26 16:50:03

1. Dev Mode To run a camel spring boot or camel main application in Kubernetes, it requires a developer to build the docker or s2i images, create Kubernetes resources and then apply the resources to a running cluster which is very time-consuming. Camel K solves this problem and saves development time with the dev mode. Simply adding a --dev flag while running code allows the developer to deploy instantly to Kubernetes and also make any changes to the running pod whenever the source file is updated. 2. Dependency Resolution We know that camel supports multiple DSL such as Java or Groovy and Camel K supports it as well. What is new in Camel K is that the automatic dependencies management feature. The developer need not worry about packaging a deployable artifact or the maven or Gradle dependencies of various components. It automatically resolves the necessary dependencies from a source file during deployment. And also only one source file is enough to run integration in a pod.

Navigating Kubernetes With Helm 3 Charts and ChartCenter

In this article, I will discuss some PWA features that provide access to your hardware APIs: Media Capture API, to take a picture (in this article called a "selfie") with your camera. https://developer.mozilla.org/en-US/search?q=Media_Streams_API Geolocation API, to determine the location of your selfie. https://developer.mozilla.org/en-US/docs/Web/API/Geolocation_API and the commonly used Background Sync API, to put the selfies in a queue or database in the meantime, so that the user can also send a selfie to the server if it is not connected. https://developers.google.com/web/updates/2015/12/background-sync Requirements To start with this tutorial you must install the following:

You need a native app. That's what we've been told repeatedly since Apple first announced the iPhone App Store. And perhaps you do. Native apps can make sense, depending on an organization's size and needs. But what about potential customers who don't have your app? Or current customers on a desktop computer? What about people with limited space on their phones who delete apps to make room for other things? What is their experience like?

Best Practices for Choosing a Go Module

With a near-endless list of Go Modules, it can be overwhelming trying to decide which is best for your Go build. For new Go developers, it can be difficult to pick a winner for your specific use case. This phenomenon is nothing new. It's one of the reasons why open-source is so important for developers. Oftentimes, when a module is published by a developer, it was likely developed to solve a specific problem that they are facing. If another developer were to use their module to solve the same problem, there may be some performance criteria needed within that module that the current version does not meet. Luckily, there are often many versions to choose from that can solve different use cases.
