A NoSQL (originally referring to “non SQL” or “non relational”) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.
In this podcast, I explain why for 99% of projects, you are probably better off with an SQL database. The need for sharded (sharding) databases, and horizontal scaling (one of the mentioned key advantages of noSQL databases) is exceptionally rare.
In this vlog style podcast, I talk about ‘programmers pain’ and the quickest way to becoming a professional developer. Whether you want to work for a company full time, start a freelancing development business, or create your own business, the strategies I teach in this video will speed things up.
Welcome to the Need2Nerd podcast! This is all about being a developer and entrepreneur. I go over recent news and answer nerd (programming and development) and entreprenerd (business, freelance and entrepreneur) questions.
I just released my Complete Freelancer course, where you will quickly learn how start, and build a very profitable freelance business.
This BRAND-NEW course (released July 16 2018) is based on my 20+ years as a entrepreneur, freelancer and developer. I’ve worked as a freelancer for years, and have hired freelancers for years. I’ve been on both sides of the deal …. that’s why this course is unique and so valuable.
Comes with 5 freelance templates, to jump start your freelance business!
Lessons are in both video and podcast/audio format … for people who want to learn on the go.
Includes an 8 page e-book that outlines the course in bullet points for easy reference.
Students are already telling me it is the most complete and to-the-point freelance training these ever seen!
Without a degree, your best chances of getting work is with a small business. Over 80% of small businesses use PHP to power their websites. So that makes PHP the #1 choice for those with no degrees.
PHP is old and sucks – no?
LOL! No! Old PHP from the 1990’s wasn’t very good, but much has changed since PHP4. Today PHP is at version 7 and it has all the ability and security as any of the other mainstream languages including:
… So don’t let uninformed nerds convince you that somehow PHP has problems. It doesn’t.
If PHP is the top language, what are the others?
How to pick the best language for you?
After 23 years of writing code and building real software, my philosophy is to be language neutral … all programming languages have their strengths and weaknesses. The choice of language just depends on:
What KIND of programming you want to do.
If you have a degree or not.
The job options in your part of the world.
… You may love Java, but if there are no Java jobs where you are, what’s the point? So the best approach is to learn the fundamentals of programming and then with your new nerd-eyes, you will be better able to judge which path to go on. I recommend learning the web stack and Python.
… All my students will tell you, you can’t go wrong with that! Check out what my students think about my courses:

I created a video on the best programming languages if you DON’T have a degree:
For database driven websites (web apps,) typically the biggest bottleneck is the database. So be sure your database is optimized. With SQL based databases, that starts with proper table design and smart indexing. That will handle 98% of websites performance needs.
How about image optimization?
Back when I started building websites, in the day of the dinosaurs (1990’s)we used to be concerned about image size, and how ‘big’ the webpages were in terms of kilobytes … but we live in the YouTube generation now, with high speed mobile internet, HD and 4k video being watched on smartphones. That means that a data limitation is typically NOT the bottleneck anymore … it’s processing (of code) on both the client and server.
If you are reading this, you probably want to learn modern web design and development, or you may already know how to build websites, but you want to become really confident in your web skills … just like all my students who took my unique web design and programming training course.
After you take my course, you will be amazed at how much you know! Below, you will find a few student quotes, screen captured from YouTube comments.
Evil, evil, evil Wix!! That is the cry of many web designers. Will Wix kill web design? Short answer: nope.
Why won’t Wix just kill web design?
Simple answer: Wix doesn’t do it all, and frankly, professional web designers should just embrace Wix as an optional tool. Yes, some small business will opt for Wix (or some other web builder,) but many will realize sooner or later, that it does have its’ limits. When small business owners figure this out, in comes the modern web designer of 2018 and beyond!
There has always been an evolution in the software field. What I have seen over and over again in the last 23 years, is the promise of amazing leaps forward, where we ONLY end up with gradual improvement.
These days we can produce web apps and websites in a fraction of the time it used to take us, but the work for well trained web developers is still there, because the bar for modern websites is just simply higher today. The tools, push the bar up. Which is good!
So yes, some older practices/jobs go, but they are just replaced with new specializations in the field. To point, Wix. Yes, a non developer / amateur can put out a basic site with Wix, but they will often lack good UI, and especially UX skills, that make sites successful.
… Wix cannot account for good UX. Yes, Wix can make a site look good. But any experienced designer knows that UX is far, far more important than UI.
For me, Wix is just another tool of the trade that smart web designers embrace.
If you want to learn web design and programming in record time, take my IWD course! It will make working with Wix, WordPress and vanilla web design, as easy as slicing an apple pie.
But when it comes to the development of high demand (in terms of performance) mobile apps, using native languages like Swift for iOS and Java for Android is still the way to go. This might change with Googles Flutter framework.
Someone asked me, if I had to pick the most important things you can do to improve your programming, what would it be?
Have a consistent self describing naming convention. This saves you yuuge time because you will make less mistakes and be able to code more quickly.
Keep your code fine-grained. This means you write functions and methods that do only 1 thing … Not five. This will keep your code easy to understand, to debug and expand.
The first thing to do when starting a new project, is to see what others have done. Perhaps there will be libraries to leverage, perhaps even entire open-source software you can use as a starting point. This is yuuge!
