What is the best way to check for an empty string in JavaScript
What is the best way to check for an empty string in JavaScript

A student recently asked me what the best way to check for an empty string in JavaScript was. I answered in the best way that I knew how and gave various methods that check for empty strings, such as checking for the value and checking the length of the variable. This left me wondering for some time after our conversation how accurate I was with my answer. And while usually code is left to subjectivity many a time, there must be one method that leans more towards the best practice or at least to improved performance.

5 reasons to make your code more readable
5 reasons to make your code more readable

The programming world is relatively split on whether more focus should be placed on code readability versus code complexity. As someone who's been working in the field for the past decade however, I have found code readability to be much more valuable for getting a project out to launch on time and for reducing the stress that can come with working on complex software.

Just recently I was in the process of writing a new blog post on Progressive Web Applications. In the post, I was going to document my conversion to a PWA site. This blog to be exact. And so I did what most developers who are attempting to learn something new would do. I jumped on Google and looked up "Progressive Web App". Lo and behold the first result seemed like the answer I was looking for. "Introduction to Progressive Web Apps". It's a good start.

This is why you need side-projects

In 2008, when I first began my professional programming career, I was tasked with working on a relatively high traffic website performing various day to day duties and bug fixes on it. Overall, a very tiring, but a very lesson filled experience. After a few years, I decide to move away from this job in pursuit of bigger and funner things in life, and luckily I had plenty of work to show for it from this past job. Plenty of the websites features were built by yours truly, and as they were public facing sites I had no issues in showing my work.

What does a programmer do exactly?
What does a programmer do exactly?

This question will have a completely different answer depending on who you ask. If you ask a front-end developer, then programming will relate more to JavaScript frameworks and client-side interaction. If you ask a back-end programmer, then you'll hear about database connections, data binding and implementing API's. Ask a data scientist, and you're bound to hear about parsing and traversing datasets with scripts written in languages such as Python or R.

Landing your first programming job
Landing your first programming job

Regardless of the field that you find yourself in, landing your first job is one of the most difficult challenges that you will face in your career. And landing your first programming job will be even more difficult, for a few reasons. But mainly, that we don't really know how to interview for a logic based job just yet. We ask you to solve puzzles, riddles and a few node traversal algorithms and you either know it, or you don't. And hopefully you don't get asked about pointers and memory allocation along the way.

New Coding Podcast Sneak Peak Episode 1

This year we will be releasing our brand new podcast Coder's Block to the general public. This is something that we have attempted to do in the past, however, podcasts are difficult as it turns out. Just getting the right software to handle the recording can be a hassle, not to mention that hearing the sound of your own voice is a trauma inducing event. But this time around, we're approaching it with a bit more knowledge on the overall process and more willing to learn as go go through the process.

Let's talk about data privacy
Let's talk about data privacy

Since Google became a verb, it has been no secret that they rely heavily on capturing user data, both to serve you better content and to serve their clients better. The clients that purchase ad space, and thus want their ads to go to the appropriate people online. So in order to do this, they have to capture non-personal (sometimes personal) behavioral data and geological data. And most of the time, the people are okay with it, because we get to use cool things like global Maps, real time navigation and a database of content so large that it would take lifetimes to sort out.

The most difficult part about programming
The most difficult part about programming

Recently I rediscovered an old project on my hard drive that had some potential to change the world (maybe). It was a year old project that was about 80% done, as is usually the case. and it was abandoned because more than likely it became boring at some point in time. So I decided to try to bring it back and shine some new life into it. At least, I attempted to. Now I'll say this, I have been a programmer for the better part of a decade now. So the coding part itself isn't normally a struggle for me. In fact, it's quite a joyful experience. The issues began as soon as I double-clicked on that launch icon, and what followed inevitably left me putting that project back into its hiding place until it is discovered again in another year.

There's a Smarter Way to Make Money

There’s a smarter way to make money than swapping time for money, and most programmers already understand the power of financial leverage in the sense that rather than earning $100 as an hourly wage, it is much better to develop an app, be that an SAS app or paid iPhone app that can then be downloaded or subscribed to multiple times without you having to do any extra work - particularly if the revenue is recurring.

traps not to fall into when selling your hard drive

If you have a few old hard drives lying around, you might be thinking about selling them to make some extra cash. However, there are a few traps you can end up falling into when you decide to sell your hard drive that you’re going to want to avoid. A study has recently shown that people who sell their old used hard drives and SSDs aren't taking the steps they need to take to wipe data from them. This is dangerous for obvious reasons; one of the biggest ones being that the buyer can access personal information, and even corporate data in some cases.
