DARK Code

Clean code. What does it mean? Often times I will watch a video about 'clean code' and it just lists off a bunch of rules. "Oh, you should do this." or "You should definitely do that." Which wouldn't be so bad if these rules were common sense and obviously right in all situations. But the problem is that almost any rule in programming can be taken too far. And no one ever tells you why you should be doing them.

So I'm developing a game in Unity and I think that game development is special in that things are always changing. You have to simulate the entire world of the game. Things will be breaking all the time and you'll have to keep on adding features. So in this maelstrom of constantly changing requirements I've learned a lot about what makes code good or bad. And I'd like to list what I've learned here.

So first of all what makes code good? First of all there's really only two things you have to optimize for as a programmer: adding features and bug fixing. I later realized there's also something else: finding bugs, but this will overcomplicate things so I'll ignore it in this post.

So adding features and bug fixing. Adding features involves knowing how the code operates so you can attach new things onto it. Bug fixing involves tracing the path of execution until you find something that looks not right so you can fix it. This usually means going through the callstack until you find something interesting. And in order to know what to look for you have to understand the code.

So in both of these cases understanding the code is incredibly beneficial. And for this reason I believe good code is code you can keep entirely in your head. So if someone asks you 'Oh, how does your code do XYZ?' then you should be able to tell them without ever looking at the code. And you should be able to keep this in your head without studying the code for a long period of time.

Now this is easier said than done. There will always be edge cases but this is the ideal.

I have four rules to keep code short and memorable. And here they are:

D - DRY - Don't Repeat Yourself

This one is pretty straightforward. Just put things in their own functions/methods. Because the less code you write the less you have to keep track of.

But if things are too different don't force it. Sure, you could make that class inherit from that other one. But what if you want to change it later? You'll have to rewrite everything.

A - Acyclic

When I first started making a game in Unity I was focusing on encapsulating everything. Making things public and private. And that worked pretty well, but then I had to debug something. And I was like "ARGH!!! Why is everything calling everything else in a cycle!?!" So then I realized encapsulation only makes sense if the things you are encapsulating are sufficiently independent.

You know one of those sequence diagrams?

If you imagine any possible sequence in your code it should only go one way. So if A calls B you should not have a scenario where in that same sequence B calls A either directly or indirectly. So it's not really Acyclic in the mathematical sense because if a class calls itself it's OK, but it's pretty close.

This makes code so much easier to debug and think about. And don't tell me this contradicts the Single Responsibility Principle because even the creator of the SRP said it's really 'Single Category of Responsibilities, not actually Single Responsibility'

R - Resiliency

Resiliency is the quality to change, to adapt. So resilient code is code that can easily be modified or change to suit a particular purpose.

So in programming there is a belief that your code has to be perfect the first time. And this leads to analysis paralysis, especially in game development where there's like 10 ways to do anything. In this rule I'm saying it doesn't matter if you're doing things the right way, as long as you code them in a way that you can change them later.

This also applies to performance. You might have heard the quote, "Premature optimization is the root of all evil". This is, like most good quotes, an exaggeration. Sure, if your code is called a lot optimize it, but if that optimization is not so important and it makes your code less resilient you have a problem.

K - KISS - Keep It Simple, Stupid

I never really understood what this phrase meant so I always put a comma after Simple and before Stupid so it would make more sense. But perhaps a better way to say this is 'Keep It Stupid Simple'.

I was actually going to call this the 'Minimum Knowledge Principle' but I couldn't really find a spot for it in my acronym so I went with KISS. What this means is your classes shouldn't do too much, your functions/methods should only take the information they need, you should practice a separation of concerns, and you should be consistent (similar features should have similar implementations). Not that your classes should 'only do one thing', I think that is complete nonsense. But they should be simple and understandable to the reader.

I was actually thinking a little about this rule. I have many places in my code where I pass a custom object (say Unit) just to get 1 or 2 parameters (say tile and health). This law says not to do that. I may refactor my code to do that less, but I'm not going to completely stop doing that because it's too convenient and I don't want methods taking like 10 parameters.

So these are my 4 guidelines for DARK code. I know, it's not the best acronym, but it's the best I got.

Keep in mind these are guidelines, not rules. They're just things to remember. It's OK to break them, especially when implementing a new feature. Because when implementing a new feature getting it working first is the most important thing. After you can refactor and ask yourself, "Is this really a good idea?"

In fact one of the reasons I decided to create my own acronym is because the competing acronym just doesn't have any good details on when to apply their principles and when not to. It's like a photocopy of a photocopy of a photocopy. Everyone remembers what was said. But not the context around it. So I hope my own acronym, as well as the accompanying descriptions, are much more clear than that.

Migrating to Volusion- A Step-by-Step Guide

Are you dissatisfied with your present e-commerce platform and contemplating to migrating to a better platform since a tad too long?

With the increase in the market for Volusion ecommerce it is all but imperative that you as an ecommerce retailer should put this platform on your wishlist.

For successful migration to the Volusion platform, you should follow some necessary steps which have been included in this guide. If you have zero knowledge about the Volusion platform, then go through this Complete Guide for Volusion E-commerce before you read this blog.

Migrating to Volusion – What you need to Know?

Now, let’s start the step-by-step guide for Volusion migration to boost your business.

1.Protect your Website Data

First and foremost the most important thing that you should take care of while migrating is to back up and store your data safely in an external hard drive.

In case, things go wrong during the process of migration (which is very rare) and you haven’t backed up your site then this could become your biggest mistake. You will lose what you’ve worked on till now and your business will suffer.

Sounds scary right? So, think wisely and do back up your data before beginning any of the tasks in the migration process.

2. Choose a Name for your New Website Platform

If you want to consider a new name to go with your new Volusion store, then you should take some preventive steps not to lose all the previous work you’ve done on your website. I understand if you want to keep the same name and move it to the same URL that will ensure you all the benefits of your previous efforts.

Do you want to enjoy all your previous marketing and SEO efforts along with a new name but there are a few extra points to take care of? The main part that you need to do is having correct 301 redirects on-site. Because 301 redirects notify Google that your site has migrated for good. Now, whatever the details collected by Google’s Crawlers about your store will be moved to you.

Also, you need to host your previous site for as long as possible for Google’s crawlers to observe 301 redirects and process them. There is no specific time to do that process but it should be done within a few weeks.

3. Sign Up for Volusion and Start ASAP

Start the migration process ASAP since it takes time to finish. If you hire Volusion developers, it is easier to complete the migration process before the required deadline. So be ready with your chosen Volusion hosting plan and talk to your digital agency to sign up for Volusion.

4. Migrating your Content & Organizing your New E-commerce Store

Transferring your content like products, customer’s details, order history, upload pictures, content pages and much more to the new e-commerce platform is important when migrating.

I know the Volusion migration process is scary! But it offers various features to make the process as smooth as possible so that you can quickly and smoothly migrate your products, customer information as well as order history with the help of Comma-Separated Values (CSV) files. These CSV files are basically spreadsheets filled with the details that the platform interprets as product details, user data, etc.

Importing CSV files into your new website can be simply done by using the Volusion Import/Export feature. Every e-commerce platform can interpret them but differently because CSV files are not standardized. You can face a lot of problems at this point. Therefore, hire an experienced team who can interpret CSVs.

5. Is Possible to Bring Previous Site Design to Volusion?

After migrating your store data to the Volusion platform, pick the best theme to make your site attractive. You have a choice to bring your previous design while migrating to Volusion but you’ll need to invest more manpower because it will be more like rebuilding your template to function on Volusion.

Choose a look that fits best for your business via Volusion template gallery. Volusion provides both free and paid templates to fulfill your requirements. You can also customize your online store with the help of our expert design team without any hassle as Volusion offers you custom templates too.

6. Configuring your Shipping and Payments Settings

The next step you should take to complete the Volusion migration process is to configure your payment and shipping settings.

You don’t need to take any stress about this aspect because Volusion accepts a large range of payment gateways together with secure and convenient inhouse merchant service. You can check the list of accepted payment gateways over here. You can also apply for Volusion credit card payments for easy payment throughout the store anywhere.

Apart from this, you should also set up your shipping methods. Provide the connection to your carrier for live shipping rates or charge your users a flat shipping fee or offer free shipping benefits to your targeted customers.

7. Adding 301 Redirects

Moving your old site URLs to the correct destination on the new platform is a very crucial step for your migration process.

301 redirects will build a seamless changeover for you and your users while maintaining your SEO value for your new online store.

Volusion offers 301 redirects manager in your Admin area to transfer your old site URLs to a new store. If you need any assistance to access the 301-redirect page, then go to your store Admin Area. Go to Settings> Maintenance and tap Manage 301 Redirects? Or else, enter a redirect manually in the table. Once that is done recheck all the previous steps before your Go Live.

8. Check Your New Webstore After Finishing Migration to Volusion

Ensure that every part of your store is working adequately along with the checkout process. Verify that the set-up of payment gateways and shipping methods are also done properly. One more aspect that you need to test before going live is to make sure your store is the main link of your storefront, categories and navigation menus.

9. Going Live with your New E-Commerce Site – Post Migration

Once you get ready to go live you will be required to subject your domain name to the Volusion DNS Servers.

If you need your store to run as root domain or sub-domain, then contact your domain name host and redirect the name servers for root domain migrations or make a CNAME record for sub-domain sites.

It takes anywhere between a few hours to 2 days for this process. If your domain name is pointed successfully then your online Volusion store will be live and you are good to go with your new Volusion store.
