When working with legacy code, the temptation to start from scratch can be strong. It’s natural to want to clean up the mess and create something shiny and new. However, rewriting code can often do more harm than good. It comes with high risks and costs, and it’s important to weigh the benefits carefully.
In his book The Hard Thing About Hard Things, Ben Horowitz states, "The primary thing that any technology startup must do is build a product that’s at least ten times better at doing something than the current prevailing way." This same principle applies to code rewrites—if the new system isn’t significantly better, then the effort isn’t worth it.
Here’s why rewrites can be dangerous:
They destabilize the codebase: A rewrite can introduce new bugs and make the code less stable, especially if the old system worked reliably.
They come at the cost of new features: When time is spent rewriting existing code, it’s not spent on adding new features that could benefit users.
Coding standards matter: Even if certain standards seem outdated or unnecessary, they are there for a reason. Diverging from established patterns can make code harder to [...]
Good commit messages are essential for a healthy codebase. They provide context, aid in collaboration, and make the history of a project much easier to follow. When you’re revisiting code after months (or even years), well-structured commit messages can help you understand what was changed and why.
To write an effective commit message, follow these practices, as recommended by Chris Beams:
Separate the subject from the body: Your subject line should be clear and concise, but if you need to provide more detail, separate the subject from the body with a blank line.
Limit the subject line to 50 characters: A short subject line ensures that it is easy to read and doesn’t get cut off in most interfaces.
Capitalize the subject line: Start your subject line with a capital letter to maintain consistency and readability.
Avoid periods at the end of the subject line: Since the subject is a brief summary, there’s no need to use a period.
Use the imperative mood in the subject line: This makes it easier to read and conveys a sense of action. For example, write "Add feature" instead of [...]
Many engineers are naturally focused on technical challenges, but one of the most important skills you’ll need throughout your career is communication. Whether you’re explaining a complex feature to a non-technical stakeholder or giving feedback in a code review, your ability to communicate effectively will shape your success.
Here are some tips on how to improve your communication skills:
1. Be Clear and Concise
When writing code, you aim for clarity and simplicity—and the same should apply to your communication. Whether it’s an email, a design document, or a code review, ensure your message is clear and to the point. Avoid unnecessary jargon, and always consider your audience.
2. Give and Receive Feedback Effectively
Feedback is crucial for growth, but it can be challenging to navigate, especially in a technical environment. When giving feedback, focus on being constructive, specific, and respectful. When receiving feedback, be open-minded and see it as an opportunity to improve, not as a personal critique.
3. Documentation Is Key
Clear documentation is a form of communication that often goes overlooked. Whether you’re writing an API spec or documenting a process, remember that well-written documentation can save hours of frustration for your team. It’s especially helpful for onboarding new engineers and ensuring that knowledge [...]
As a software engineer, learning from others is crucial for developing new skills and growing professionally. One of the best ways to achieve this is by shadowing experienced engineers and engaging in pair programming.
1. Shadowing: Learn by Observation
Shadowing allows you to follow a senior engineer and observe their approach to solving complex problems. It's an active process where you take notes, ask questions, and learn how experts handle various scenarios. To maximize the benefits of shadowing, plan sessions ahead of time and have a follow-up discussion afterward to reflect on your learnings.
Once you feel more comfortable, try the reverse: have a senior engineer shadow you. This method offers invaluable feedback and provides a safety net if something goes wrong, especially in high-pressure situations like interviews.
2. Pair Programming: Learning Through Collaboration
Pair programming involves two engineers working together to write code. One types, while the other reviews and thinks ahead. It takes time to get used to, but the benefits are significant: quicker learning, better communication, and higher code quality.
Pair programming isn’t just for new engineers. Teammates at all levels can benefit from exchanging ideas and perspectives. The collaborative environment fosters mutual growth, making it one of the most effective ways to [...]
Two psychological challenges can slow your growth as a software engineer: impostor syndrome and the Dunning-Kruger effect. Both can affect how you perceive your abilities, and understanding them is key to overcoming these growth obstacles.
1. Impostor Syndrome: Feeling Like a Fraud
Impostor syndrome occurs when highly capable engineers feel like they don’t deserve their success. Every mistake reinforces their self-doubt, while their achievements are attributed to luck. This self-perpetuating cycle can be hard to break.
To overcome it, start by recognizing your accomplishments—no matter how small. Reframe negative thoughts to highlight the progress you’ve made. Talking to trusted colleagues about your self-doubt can also provide valuable reassurance and feedback.
2. The Dunning-Kruger Effect: Overconfidence Despite Incompetence
On the flip side, the Dunning-Kruger effect is when individuals overestimate their abilities because they don’t yet know what they don’t know. These engineers might reject feedback and believe their approach is always right, leading to frustration among teammates.
To combat this, foster curiosity and humility. Engage in discussions about design decisions, even when you disagree. Ask for feedback and embrace the idea that there are often trade-offs rather than one “right” solution. A mindset of continuous learning will help you grow.
In today's world of rapidly-evolving technology, deploying and managing applications efficiently and securely has become a top priority for businesses of all sizes. Docker and Kubernetes are two powerful tools that have emerged as popular options for deploying and managing applications in a modern, cloud-native environment. In this blog post, we will discuss why Docker and Kubernetes are a good deployment option.
What is Docker?
Docker is a containerization technology that enables developers to package and run their applications in a standardized environment, making it easier to deploy and manage them across different systems. Docker containers are lightweight and portable, making them ideal for building, shipping, and running applications in any environment, including on-premise, public or private clouds, and hybrid clouds.
What is Kubernetes?
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. Kubernetes provides a framework for running and managing multiple Docker containers, allowing developers to build complex applications that can be deployed across multiple nodes in a cluster. Kubernetes also provides a set of tools for monitoring, logging, and scaling applications, making it easier to manage large-scale deployments.
Why Docker and Kubernetes?
Docker and Kubernetes provide a number of benefits for deploying applications in a modern, [...]
