<h1 id="not-understanding-slice-length-and-capacity">Not understanding slice length and capacity</h1>
<p><a class="glightbox" href="../img/20-slice.png" data-type="image" data-width="auto" data-height="auto" data-desc-position="bottom"><img alt="" src="../img/20-slice.png" /></a></p>
<p>Its pretty common for Go developers to mix slice length and capacity or not understand them thoroughly. Assimilating these two concepts is essential for efficiently handling core operations such as slice initialization and adding elements with append, copying, or slicing. This misunderstanding can lead to using slices suboptimally or even to memory leaks.</p>

<p>Interfaces are one of the cornerstones of the Go language when designing and structuring our code. However, like many tools or concepts, abusing them is generally not a good idea. Interface pollution is about overwhelming our code with unnecessary abstractions, making it harder to understand. Its a common mistake made by developers coming from another language with different habits. Before delving into the topic, lets refresh our minds about Gos interfaces. Then, we will see when its appropriate to use interfaces and when it may be considered pollution.</p>

<p>A misconception among many developers is believing that a concurrent solution is always faster than a sequential one. This couldnt be more wrong. The overall performance of a solution depends on many factors, such as the efficiency of our code structure (concurrency), which parts can be tackled in parallel, and the level of contention among the computation units. This post reminds us about some fundamental knowledge of concurrency in Go; then we will see a concrete example where a concurrent solution isnt necessarily faster.</p>

<p>In previous sections, we have discussed the fundamental concepts of CPU caching. We have seen that some specific caches (typically, L1 and L2) arent shared among all the logical cores but are specific to a physical core. This specificity has some concrete impacts such as concurrency and the concept of false sharing, which can lead to a significant performance decrease. Lets look at what false sharing is via an example and then see how to prevent it.</p>
