Effective Coding With Java Observability

Aggregated on: 2023-07-21 19:46:14

There are many common mistakes I’ve seen repeated over the years while trying to make observability initiatives successful. However, the most critical and fundamental of these organizational stumbles is the irresistible infatuation with technology and toolings themselves. It should not come as a surprise. Many "let’s add observability platform X" projects start off with plenty of fanfare but also a very hazy sense of direction and extremely muddled criteria for success. The vision of what effective observability can do to actually help developers work better is suspiciously missing from the preaching of many of its commercial vendors and oracles. Ask yourself: how often do you find yourself taking your eyes off the code in the IDE to find out what you can learn from its execution data?

Mastering API Data Retrieval: A Comprehensive Guide to Filtering and Sorting

Aggregated on: 2023-07-21 17:46:14

APIs can return vast amounts of data, making it challenging for developers to retrieve only the information they need. This is where filtering and sorting come in.Filtering and sorting are two essential features of API design that allow developers to efficiently retrieve specific data from an API. Filtering enables developers to narrow down the results of an API query by specifying criteria that the returned data must meet. Sorting, on the other hand, lets developers arrange the returned data in a specific order, such as by date or alphabetical order.Properly implementing filtering and sorting in APIs can significantly enhance performance and user experience. In this article, we'll dive into the specifics of filtering and sorting in APIs, discussing best practices and common mistakes to avoid. By the end of this guide, you'll have a thorough understanding of how filtering and sorting can streamline API data retrieval and improve your software integration processes. Filtering in APIs What is filtering in APIs? Filtering in APIs is the process of narrowing down the results of a query to retrieve only the data that meets specific criteria. When an API receives a request, it can filter the data based on parameters such as dates, keywords, IDs, or other user-defined criteria. By filtering the data, developers can reduce the amount of information returned in a query, making it more efficient and easier to work with. Effective filtering is crucial for APIs that return large datasets, as it can significantly improve performance and reduce the amount of data that needs to be transmitted over the network.

Learning from Incidents Is Not the Goal

Aggregated on: 2023-07-21 00:01:14

Learning from incidents has become something of a hot topic within the software industry, and for good reason. Analyzing mistakes and mishaps can help organizations avoid similar issues in the future, leading to improved operations and increased safety. But too often we treat learning from incidents as the end goal, rather than a means to achieving greater business success. The goal is not for our organizations to learn from incidents: It’s for them to be better, more successful businesses. I know, how corporate. The more we learn, the more successful we are, and the cycle continues. We learn because we want to succeed. The Growing Gap Between Theory and Practice You might conclude that I don’t care about learning from incidents; I do, deeply. But I care about learning from incidents because more informed, more experienced people are going to be more effective at their jobs, and likely happier, too. A culture of learning is good for the people that work here, it’s good for our customers, and ultimately, that’s good for business. The more we learn, the more successful we are, and the cycle continues. We learn because we want to succeed. I’ve seen a considerable amount of research and effort being applied to study of learning from incidents in software, and a lot of interesting and thought provoking material shared as a result. Often though, what I see highlights a growing gap between the academia and the practical challenges that most face on a day-to-day basis. I’m not ashamed to say I’ve given up on reading papers or watching some talks because they felt so wildly disconnected as to be useless. I spend every working day thinking about, and talking with people about incidents and it feels impenetrable to me — that feels wrong. Most Organizations Are Struggling With the Basics At incident.io, I’m fortunate to work with a diverse set of customers: from 10-person startups to enterprises with tens of thousands of employees. For the majority of these customers, the problem isn’t anchored in academic concepts and complex theories. It’s a lot more fundamental. Many struggle to define what an incident is, how they should react when something goes wrong, or how to make sure the right people are looped into the right incidents so things run as smoothly as possible. When it comes to post-incident activities, they don’t know how to run an incident debrief, they can’t keep track of follow-up actions, and they’re stuck trying to convince their senior leaders that targeting an ever reducing mean time to recovery isn’t a great idea (Pro tip: It’s not a good idea). Connecting Learning, Change, and Business Outcomes If you’re are trying to improve the incident culture at your organization, or convince your management that an investment of time to really learn from a major incident is a good idea, an academic approach just doesn’t work. Telling someone who wants a report on the root cause that there’s “no root cause” alienates the very people we need to convince. If we want buy-in from the top, more needs to be done to take people on the journey of zero-to-one, and that means connecting learning and change to tangible business outcomes. None of this is meant to criticize the good work of the incident community. There are plenty of folks doing excellent work and extolling the value of more practically focused incident management. But I’ve equally seen what I consider to be semi-harmful advice given too. Advice around devoting days or weeks of effort to investigate even the smallest of incidents. I’m almost certain you’ll be able to learn something, but does the return on investment justify it? And then there’s all the things people are told they shouldn’t be doing, like reducing incidents down to numbers for comparison. Yes, MTTR is fundamentally flawed metric, but when you have a conversation about replacing it with people who believe it’s useful, what are you suggesting? Most people are time constrained and if they’re told to draw the rest of the owl, they simply won’t. Practical Advice for Incorporating Learning into Your Organization I've been at the business end of highly effective incident management programs, semi-broken ones, and many in between. What’s common among the high performers is the fact that a healthy culture has started from a position of engaging the whole organization. Learning is connected to practical benefits that everyone understands, and there’s been a person (or group of people) at the heart of the culture, applying time and effort to meet people where they are and bring them on the journey. Learning has never been positioned as the primary motivator, it’s been a side-benefit of more business-oriented objectives. So, to make this a little more action focused, here’s a few tidbits of advice for how to practically synthesize learning alongside your role. Think Carefully About the Return on Investment of Your Actions Nothing will put roadblocks up faster than work being done without good justification for how it helps the business. Whether you think it’s meaningful or not, if you’re spending a week performing a thorough investigation of an incident that degraded a small part of your app for a few minutes, you’re unlikely to win over anyone who cares about delivering on the broader priorities of the organization. This might mean less time (or no time) spent on these incidents, in favour of using more significant ones. Use Transparency as a Catalyst for Serendipitous Learning Whether you like it or not, folks learn. Collisions of teams, individuals, and systems result in knowledge transfer and a front row seat to expertise in action. If you’re looking for the fastest way to learn from incidents, the best starting point is making them very visible to the whole organization, and actively celebrate great examples of incidents that have been done well. Don’t underestimate the power of implicit learning that happens alongside everyone just doing their job. Sell the Upside of Changes, Rather Than Telling People What They Shouldn’t Do If your leaders believe a monthly report on shallow incident data, like MTTR and number of incidents, is the most useful for way for them to understand the risks facing the business, you’ll struggle to wrestle it out of their hands. And if you haven’t got a concrete answer for what they should be looking at instead, telling them what they shouldn’t do simply isn’t helpful. First, find a better way. Give them a qualitative assessment of the risks and a handful of key learnings alongside their numbers. If what you have is more valuable and useful, removing the numbers becomes an easy task. Ultimately, if you’re struggling to make change to how your organization learns from incidents, start small, start practical, and connect the activity to something that advances the goals of your business. It’s absolutely fine to cherry-pick more academic concepts and sequence them alongside less valuable practices that many organizations are anchored to today. Incremental improvements compound over time, and every small change can aggregate to something meaningful.

The Windows Server Failover Cluster (WSFC) is one such cluster solution. It's available as part of Windows Server Datacenter edition deployments. This makes it a default choice for setups that are using Windows Servers. Note that the SAP HANA database is only currently released for Linux (SUSE and RHEL). Hence in such setups, the WSFC can be used for SAP Central Services (ASCS/SCS). For MS-SQL deployments, the WSFC is also used to provide high availability with SQL Always On.

Linked List in Data Structures and Algorithms

Aggregated on: 2023-07-18 18:01:12

In the previous blog, we looked into different types of linear data structures. A linked list is also one of them. The program for linked lists seems to be lengthy, but once we are aware of the concept, It's easy to implement it. Linked lists are unlike stack and queues as it stores a pointer pointing to the address. For example, while we are listening to music on Spotify, we can create our song playlist and can play a song from both starting and end of the list. These music players are implemented using a linked list. In this blog, we further discuss linked list implementation, how it is related to data structures, and its real-time applications.

It makes sense for DevOps engineers and architects to perform canary deployments in their CI/CD workflows. They cannot skip testing a release for the sake of adhering to continuous delivery practices, can they? In canary deployments, the new version, called canary, is tested with limited live traffic at first. Ops teams and SREs then observe and analyze the performance and customer experience of the canary, before gradually rolling it out for the larger audience in case of no issues.

Datasets Staticity Levels

Aggregated on: 2023-07-18 17:16:13

A common challenge when designing applications is determining the most suitable implementation based on the frequency of data changes. Should a status be stored in a table to easily expand the workflow? Should a list of countries be embedded in the code or stored in a table? Should we be able to adjust the thread pool size based on the targeted platform? In a current large project, we categorize datasets based on their staticity level, ranging from very static to more volatile:

Keep the Monolith, but Split the Workloads

Aggregated on: 2023-07-18 16:46:13

I’m a big fan of monolithic architecture. Writing code is hard enough without each function call requiring a network request, and that’s before considering the investment in observability, RPC frameworks, and dev environments you need to be productive in a microservice environment. But having spent half a decade stewarding a Ruby monolith from 20 to 200 engineers and watched its modest 10GB Postgres database grow beyond 5TB, there’s definitely a point where the pain outweighs the benefits.

The Use of Biometrics as a Cybersecurity Method

Aggregated on: 2023-07-18 16:16:12

Introduction to Biometrics Biometrics measures and analyses an individual's physical and behavioral characteristics. It is a technology used for proper identification and access control of people under surveillance. The theory of biometric authentication is that everybody can be accurately identified by intrinsic physical or behavioral traits. The word biometrics is derived from the Greek words bio, meaning life, and metric, meaning to measure. Biometric identifiers are unique and measurable characteristics used to label and describe individuals. They are often classified as physiological characteristics related to the body's shape. Examples include but are not limited to, fingerprints, palm veins, face recognition, DNA, and iris recognition. Behavioral characteristics involve a person's behavior pattern, such as a mouse's movement, typing rhythm, gait, signature, and credentials. Some researchers have coined the term behavior metrics to describe biometrics in behavioral patterns.

API Gateways: Enabling Effective API Versioning in Microservices Architecture

Aggregated on: 2023-07-18 16:01:12

API Gateways in a Microservices Architecture In a microservices architecture, where applications are built as a collection of small, independent services, API gateways serve as a central entry point for all external client requests. An API gateway acts as a mediator between clients and the individual microservices, providing a unified interface to access the system's functionalities. Rather than directly interacting with each microservice, clients communicate with the API gateway, which handles various responsibilities such as routing requests, enforcing security measures, performing transformations, and aggregating data from multiple microservices. It acts as a traffic controller, allowing clients to access the services they need without needing to know the specific details of each microservice's API.

In order to be able to leverage various capabilities of the Java Streams, one shall first understand two general concepts – the stream and the stream pipeline. A Stream in Java is a sequential flow of data. A stream pipeline, on the other hand, represents a series of steps applied to data, a series that ultimately produce a result. My family and I recently visited the Legoland Resort in Germany – a great place, by the way – and there, among other attractions, we had the chance to observe in detail a sample of the brick-building process. Briefly, everything starts from the granular plastic that is melted, modeled accordingly, assembled, painted, stenciled if needed, and packed up in bags and boxes. All the steps are part of an assembly factory pipeline.
