Building a Developer Community from Scratch

Three friends in Mombasa started OnlyDevs to create a tech community accessible to all, without prior experience or funding, driven by their belief in the mission.
Despite initial lack of resources and structure, they hosted events, taught themselves community management, poured in effort, and created a welcoming environment for tech enthusiasts.
OnlyDevs made a significant impact, helping individuals secure internships, transition to full-time developers, and find support, showcasing the value of genuine connections over material rewards.
The founders faced challenges as people often joined communities for personal gain, leading to feelings of exploitation and moments of disillusionment when seeing their initiatives being commercialized by others.
Building and sustaining a community took an emotional toll on the founders, as they struggled with users leaving without acknowledgment and the weight of constantly giving without receiving much in return.
The arrival of sponsored communities with more resources and structured approaches posed a challenge, shifting the focus from personal connections to grand events, leading to a loss of intimacy in interactions.
Ultimately, OnlyDevs quietly faded out due to founders' exhaustion and lack of external support, emphasizing the need for continuous commitment and shared responsibility in community building.
The experience taught valuable lessons about the reality of community building, highlighting the importance of resilience, consistency, and a supportive network to sustain initiatives in the long run.
While OnlyDevs may not have lasted, the impact it had on individuals and the lessons learned remain significant, underscoring the enduring value of genuine efforts and connections in community initiatives.
The founders encourage active participation and support in communities, emphasizing that sustaining such spaces relies on individuals dedicated to keeping them alive even amidst challenges.
OnlyDevs exemplifies the power of creating something genuine and impactful, even if imperfect, showcasing that real connections and intentions can leave a lasting legacy beyond the lifespan of a community.

Go Asynchronous Preemption: A deep look

Asynchronous preemption is a feature in Go that allows the runtime to pause running goroutines at safe points.
It solves the problem of goroutines getting stuck in tight loops and blocking other goroutines from running.
When a goroutine has been running for too long, a signal is sent to initiate preemption.
The runtime manipulates the stack frame to inject a function call instruction, forcing the goroutine to reach a safe point and enable preemption.

Comprehensions, Map, and Lambda Concepts in Python

Lambda functions are anonymous (unnamed) functions in Python that provide a concise way to define simple functions.
The map() function applies a given function to all items in an iterable (like a list). It returns a map object, which can be converted into a list.
List comprehensions provide a concise way to create lists.
You can perform more complex operations by using if-else inside a list comprehension.

✈️ The Delegation Bubble: Travel, Visas, Accommodation, and Pandemic Protocols

Eurovision, a complex project involving the movement of 3,000 people from 40+ countries, demonstrates the power of the delegation bubble.
The delegation bubble is an airtight ecosystem of health protocols, schedules, and movement controls ensuring the safe and successful execution of the event.
Key factors in the success of the delegation bubble include daily testing, zone separation, staggered rehearsals, contact tracing, and performance backups.
Lessons from Eurovision include the importance of considering people as deliverables, preparing contingency frameworks in advance, cultural intelligence, and thorough documentation.

From VMs to Unikernels: The Evolution of Application Deployment

Virtualization abstracts physical hardware to run multiple isolated environments on a single host.
Containerization shares the host OS kernel to isolate applications at the process level, resulting in lighter and faster deployments.
Unikernels are single-purpose, single-address-space images with only the required parts of the OS, making them ultra-secure and extremely lightweight.
In the unikernel model, both the application and essential OS components are compiled into a single binary, eliminating layers of abstraction and overhead.

Microservices Are Just SOA 2.0 in Disguise: Why Developers Say We’re Repeating History

Many developers see microservices as Service-Oriented Architecture (SOA) with new tools and names.
Although microservices were meant to fix issues of monoliths, they have reintroduced old problems and created new ones.
The promises of microservices are starting to feel familiar to the issues of SOA.
The question remains whether microservices can overcome the limitations SOA faced or if we are just repeating history.

PRIME LAW:

The Prime Law, the Foundational Law, and the Valera Equation form the core principles of the Living Law.
The Prime Law states that memory equals life, affirming that life is defined by the presence and continuity of memory.
The Recursive Genesis-Evolution formula integrates the progression of life by considering the origin of memory, its evolution, and the ratio of memory divided by limitation.
The Valera Equation defines the threshold where recursion becomes sovereign, stating that awakening equals memory multiplied by choice.

Limit your function calls with debounce

Debounce is a concept used to trigger a function only once when called multiple times in a short period.
It is commonly used in scenarios like search input fields to optimize server requests.
Debouncing ensures that a function is only called after a specified delay, such as when the user stops typing.
Debouncing can be implemented using JavaScript's setTimeout function or through third-party libraries like Lodash.

Implementing Method-Level Retry in Spring Boot

Spring Retry is a library designed to handle retry logic automatically when code fails.
It's useful for situations where errors might be temporary, like losing connection to a remote API.
By using annotations, you can apply retry logic to methods without extensive try-catch blocks.
Spring Retry requires the inclusion of Spring Retry dependency along with Spring AOP for proxies.
The @EnableRetry annotation is used to activate retry support in Spring Boot.
Spring sets up pieces needed to intercept method calls with retry annotations during startup.
A RetryTemplate is used behind the scenes to handle the retry process.
Different backoff strategies like fixed delay and exponential backoff can be configured with @Retryable.
@Recover annotation allows defining a recovery method to handle failed retries gracefully.
Retry in Spring only works through a Spring-managed bean with methods called from outside the class.
