 Too often I neglect the idea of UX design in backend work. The goal of user experience design is to give users a product that's easy to use. In the world of front-end development, that typically means making it obvious how to navigate your site, using commonly-understood icons, or implementing well-contrasted colors for foreground and background, making your site easy to read.

 "Dead Poet's Society" is a classic film, and has become a recent favorite of mine. There's a scene in particular that I enjoy, where Robin William's character explains that it's bad practice to use terms like "very tired" or "very sad", instead we should use descriptive words like "exhausted" or "morose"!

 Functional programming is a way to write code where programs are created strictly through functions. Functional programming has gained quite a bit of traction in recent years among the development community, mostly because of the benefits it provides.

 I've noticed that bugs introduced into an existing code base are often due to poor variable naming more than one might suspect. For example, a developer uses a `rateLimit` variable expecting it to be denominated in _seconds_ while it represents _minutes_, resulting in a 6x slower schedule. Another developer expects `dbConnection` to be an open database connection, but instead, it's just the connection URI.

 I recently had a ticket opened on my team's backlog board requesting the ability to bypass our API's caching system. For context, our front-end team uses my team's API to make fairly heavy requests to ElasticSearch, and one of the features of our API gateway is to cache the results of heavy aggregations for ~30 seconds. It turns out, every once in a while they need to run two of the same query within the ~30-second caching window and want an updated result set.

 There is a common trap that we fall into as developers, and it is believing that because some code "worked" that the code was written "correctly". In reality, for most technical problems, a good developer can likely point out several different solutions. Any of those solutions might be perfectly reasonable, while none of them is the single "correct way".

 Be careful about deciding the best way to learn to code. Not all paths are equally effective. Self-taught developers and [bootcamp graduates often struggle](/jobs/getting-a-job-after-coding-bootcamp-is-hard/) a lot to find their first coding job. In my experience, it's much easier to get your foot in the door when you spend the time learning the CS basics that so many "crash courses" skip over when trying to get students to dive directly into the deep end of application code.

 It's really hard to get your foot in the door for engineering interviews, especially if you have no experience and are looking for an entry-level position. Often times, more experienced candidates looking to find a [higher-paying job](/computer-science/highest-paying-computer-science-jobs/) can also have trouble. As an employer myself, I can tell you that one of the biggest mistakes I see in 75% of resumes is using a _visually boring template_. When I'm sifting through forty or fifty applicants, it's really easy for my eyes to glaze over. Think of your resume as your website landing page. You need to catch your employer's attention by calling out your biggest accomplishments and selling points at a glance.

 The most important thing to understand about these two fields of study is that, ultimately, they are similar. At the end of the day, Software Engineering and Computer Science will both help to make you a better programmer and developer, and the only difference between the two is how they are applied. Software Engineering tends to be more practical, and Computer Science tends to be more theoretical. In a way, Software Engineering is just applied Computer Science, and using that as a starting point, we can examine the differences between the two.

 Heuristics in [computer science](/computer-science/comprehensive-guide-to-learn-computer-science-online/) and artificial intelligence are "rules of thumb" used in algorithms to assist in finding approximate solutions to complex problems. Often, there's simply too much data to sift through to come to a solution promptly, so a heuristic algorithm is used to trade exactness for speed. However, because heuristics are based on individual rules unique to the problem they are solving, the specifics of the heuristics vary from problem to problem.

You don't need a degree from an accredited university in 90% of cases, but you do need to learn the material, whether it be online, on the job, or in a formal setting. Let's explore the most common computer science job titles and their associated compensation, details, and duties.

 Bubble sort is named for the way elements "bubble up" to the top of the list. Bubble sort repeatedly steps through a slice and compares adjacent elements, swapping them if they are out of order. It continues to loop over the [slice](/golang/golang-make-maps-and-slices/) until the whole list is completely sorted.

 Needing to be a math genius to [learn to code](https://www.boot.dev) is a thing of the past. High-level programming languages offer an alternative to low-level machine code, which makes coding more accessible than ever. Let's dive into how Golang, a modern higher-level language, matches up to C++, a tried-and-true low-level language. We'll cover the most important points like which language is more performant, which is easier to learn, which results in cleaner code, and which programming methodologies guide their respective designs.

 Insertion sort builds a final sorted list one item at a time. It's much less efficient on large lists than more advanced algorithms like quicksort or [merge sort](/golang/merge-sort-golang/). Insertion sort is a simple algorithm that works just like you would arrange playing cards in your hands. A slice is first split into sorted and unsorted sections, then values from the unsorted section are inserted into the correct position in the sorted section.

 Go has a powerful standard library that makes string manipulation easy right out of the box. One of the functions I use most often is the [strings](https://golang.org/pkg/strings) package's [Replace()](https://golang.org/pkg/strings/#Replace) function. `strings.Replace()` returns a *copy* of its input string after replacing all instances of a given substring with a new one.

 Scala and Golang are newer languages, only coming onto the scene after the turn of the century, but in that time they've managed to become two of _the_ [highest-paid languages](https://insights.stackoverflow.com/survey/2020#technology-what-languages-are-associated-with-the-highest-salaries-worldwide-united-states) for developers, with the industry benefiting from their fresh creation.

 If you're asking "should I commit the vendor folder in my Go project to Git?", the answer is "almost always". Let's talk about why committing is generally better than not.

 I can't begin to tell you how often I split strings in Go. More often than not I'm just parsing a comma-separated list from an environment variable, and Go's standard library gives us some great tools for that kind of manipulation.

 The Go standard library makes concatenating strings easy. Concatenation is just a fancy word for adding strings together to make a larger string. For example, if we concatenate `"hello"`, `" "` and `"world"` we'd get `"hello world"`.
