What Is a Functor? Basic Theory for Java Developers

Aggregated on: Wed Dec 08 2021 21:04:15 GMT+0000 (Coordinated Universal Time)

In general, a Functor is a concept originating from mathematics, to be exact from a part of mathematics called category theory. In my very first article, I described in detail a similar concept known as Monad. Here I want to continue that thread, so I will try to give you some more insight into Functors — what they are, how they work, and what the theory behind them is. I will also implement a simple functor to better understand how they work and why using them may be a clearer solution. The source code for this article is available in GitHub repository.

Avoiding Alert Fatigue: 8 Tips for Every K8s Engineering Team

Aggregated on: Wed Dec 08 2021 20:34:15 GMT+0000 (Coordinated Universal Time)

If you have been a part of an on-call team, you probably know what alert fatigue is and what it can do to your health. And when Kubernetes is involved, the number of alert sources can skyrocket quickly. This article will reflect on some common causes of alert fatigue and share tips to help reduce it. What Is Alert Fatigue? In simple terms, alert fatigue happens when you receive a large number of work-related alerts in a day, even if they are non-actionable. An unreasonably high number of alerts can kill your productivity because you will be taking too many breaks from your work to acknowledge alerts now and then.

Cloud technology is hands down one of the biggest tech revolutions of our times. It’s sheer magic just to think of the fact that you could run an entire organization out of a remote location and still access features and modules as seamlessly as you would in your premise. With the competition being stiff in the cloud technology space, there are multiple vendors who are eyeing the attention and time of users to get to use their solutions. At the same time, companies of all sizes and scales – from small businesses to enterprises – all want to spend the minimum on setting up and maintaining their own cloud space.

Why General Inheritance Is Flawed and How to Finally Fix It!

Aggregated on: Wed Dec 08 2021 16:34:15 GMT+0000 (Coordinated Universal Time)

General inheritance, whereby a public class is extended over package boundaries, provides a number of challenges and drawbacks and should be avoided in almost all cases. Classes and methods can be made final meaning that subclassing is disallowed which effectively prevents inheritance. While this may sound like a strange thing to do in an object-oriented language like Java, it does carry significant benefits for a large number of class types. But, when should a class or method be final, and just why is general inheritance problematic?

Federated Learning: Collaborative Machine Learning With a Tutorial

Aggregated on: Wed Dec 08 2021 14:49:15 GMT+0000 (Coordinated Universal Time)

Federated Learning: Privacy, Security, and Data Sovereignty in the Lab and in the Wild (with Tutorial) Federated learning, also known as collaborative learning, allows training models at scale on data that remains distributed on the devices where they are generated. Sensitive data remains with the owners of said data, where training is conducted, and a centralized training orchestrator of training only sees the contribution of each client through model updates. Federated learning doesn’t guarantee privacy on its own (we'll touch on breaking and repairing privacy in federated learning systems later on), but it does make privacy possible.

Keystone Interface and Keystone Flag

Aggregated on: Wed Dec 08 2021 13:49:15 GMT+0000 (Coordinated Universal Time)

As we all know, software developers may ease their development process by integrating their work as often as they can. It is also known that releasing frequently into production helps a lot. But developers and project stakeholders don’t want to expose half-developed features to their users. So, what happens in this case? A useful technique to deal with this issue is to build the backend, integrate, but don’t build the user interface. The feature can be integrated and tested, but the UI is held back with the help of a keystone ( more info you may find in Martin Fowler’s blog ) and added only when the feature is completed, showing it to the users.

Building Our Database Connection Guide Using Next.js

When we set out to build a comprehensive Connection Guide for Databases, we looked for what web framework to build with. Next.js was a clear choice. Especially for a 100+ page, wiki-style repository with a formulaic structure, Next.js made coding and pushing the site a delight. Why Build a Database Connections Guide? Arctype is a SQL client that strives for speed and simplicity.

Fail-Fast Reliable Software Strategy: Debug Failures Effectively

I love cooking and use my Thermomix a lot. If you hadn’t heard about that amazing innovation, it's a kitchen robot… Well, it’s a magical super cooking machine. When designing the Thermomix, its designers took the approach of fail-safe instead of fail-fast. This is a smart choice in this case, but it has its drawbacks. E.g. my machine tried to recover from a failure which sent it into an infinite recovery loop. I literally couldn’t pull out the food from the lid that was sealed shut. But normally, it’s one of the most reliable devices I own.

How to Integrate Google Workspace With Oracle APEX and Oracle Database: Part 2

Aggregated on: Tue Dec 07 2021 21:04:14 GMT+0000 (Coordinated Universal Time)

In the first part of the article, I introduced Google Workspace and Google APIs and told you a little bit about them. I've also shown you how to properly configure the Google API console. Now, let's talk about the main thing: integrating Google Workspace with Oracle Database and an application created in Oracle Application Express. There are two ways you can do that. Method #1: Integration With Oracle Database and APEX Application Using Google API Client Library for JavaScript We can start the configuration of the Oracle Database and APEX application. At this point, we created a Google API project with configured consent screen, and Google Drive API enabled. Now, we will add an entry to the ACL access list with the address to Google API. Then we will create an Oracle Wallet, where we will put the certificate responsible for communication with Google API via HTTPS. I will also mention — as a side note — a crucial detail that should be remembered when creating a wallet.

SIEM Should Focus On Active Threat Detection Over Operational Tasks

Aggregated on: Tue Dec 07 2021 17:34:14 GMT+0000 (Coordinated Universal Time)

SIEM tools have become more challenging to set up, manage, and use on a day-to-day basis. Busy security teams find themselves overwhelmed by the SIEM solution itself, and this takes their focus away from the actual threats they need to identify and stop. The solution is to offload key threat detection capabilities from the in-house team to a SIEM solution, or service provider. This frees up the in-house security team to focus on strategic initiatives, and importantly, results in more secure systems. Operational Duties Eclipse Security A SIEM solution should excel at helping teams identify threats and mitigate them. In recent years, there has been a focus on mitigation, and neglect of actually identifying threats. SIEM has become all about operations and compliance, and less about security. Security teams have reflected this trend. They spend a bulk of their time collecting logs, parsing them, storing them for three months or more, dealing with alerts when they come up, and bringing down the meantime to recovery/response.

Every company is a software company today, and things change drastically in the software industry. Therefore, organizations are required to be more agile to cope with the ever happening changes in the industry. While DevOps methodologies focused on software delivery speed, security left behind gave rise to so many security threats and exploits. That is where we saw a movement of DevSecOps - security being the default and foremost aspect of the SDLC rather than an afterthought. When not appropriately handled, security vulnerabilities can ruin the organization's overall reputation, and hence it is important to understand how security vulnerabilities impact your organization.

Slow Database = Slow Application by Connor McDonald

Your modern application ticks all the boxes - serverless, functional, kubernetes, kafka, microservices, API-based, the list goes on. And it runs on every OS and every type of device! But unfortunately ... all of this counts for NOTHING if your data access is slow. And speeding up data access typically means understanding the fundamentals of how SQL is processed by the database. For novice developers, SQL can be hard to understand and sometimes totally hidden from view under an ORM. This session will peel back the covers to show how SQL is processed, how to avoid getting hacked, and how to get data back to your application in a snappy fashion.

Introduce GitOps Across Any Infrastructure Without Adding Complexity

Aggregated on: Tue Dec 07 2021 10:04:14 GMT+0000 (Coordinated Universal Time)

GitOps is quickly gaining popularity as a continuous deployment solution, offering full application and infrastructure management through a Git-based workflow. But on this road to (workflow) riches, organizations quickly encounter two hurdles impeding their GitOps adoption. First, available GitOps tooling is overwhelmingly Kubernetes-centric. Aside from born-in-the-cloud companies, most organizations rely on a mix of technologies from on-prem and cloud VMs to Kubernetes. Using GitOps to define and deploy applications on Linux VMs is far different from doing so with Kubernetes, burdening developers with the complexity of managing those multiple pipelines. Second, no matter what infrastructure developers deploy applications to, GitOps lacks a centralized portal to help monitor and support those applications.

Well, that is an actual use case I've been assigned to by a friend. Hence, obviously time is of the essence, while at the same time I can probably assume the guy is fairly self driven and can research all the gory details on his own if given some pointers. My friend's friend has a college degree, so I can also assume he's self driven, motivated and able to indulge in long self studies once given a few pointers in the right direction. He is also a fairly smart guy, but literally knows nothing about software development. If the above is a fitting description for you too, you've come to the right place.

Backlog Refinement or Backlog Grooming

Aggregated on: Mon Dec 06 2021 16:04:14 GMT+0000 (Coordinated Universal Time)

In order to get everybody on the team aligned, teams plan the work that should be done in the next sprint. The purpose of sprint planning is to agree on a goal for the next sprint and the set of backlog items to achieve it. Sprint planning is about prioritizing backlog items and agreeing on the number of backlog items in the sprint based on team capacity. Sprint planning kicks off every sprint. Scrum suggests investing two hours per sprint week in planning sessions. Experienced teams will be able to cut this down to an hour per week or less. Mostly because they are comfortable with less detail upfront and more uncertainty in their definition of ready. The meeting is attended by the entire team. Outside stakeholders are invited if they can provide additional expertise for specific backlog items. Today we will discuss a very important topic: backlog refinement vs backlog grooming. Backlog Refinement or Backlog Grooming Backlog refinement or backlog grooming stands for keeping the backlog up to date and getting backlog items ready for delivery. This involves rewriting backlog items to be more expressive, deleting obsolete ones, re-assessing the relative priority of stories, splitting big items into smaller ones, resorting them, and correcting estimates in light of newly discovered information.
