Working From Home - A Developer's View

Long before COVID-19, I (and my team) started working from home. Even before working at CakeDC, between 2007 and 2010, I worked for a company where you were able to split your time between home and office. 

 

Maybe that's why I actually feel comfortable working remotely and I would never change it for an in office position anymore.

 

 

Anyway, I am not going to talk about remote work because these days there are thousands of articles about it (even in  one of our previous posts). I want to focus today on writing about our experience with different communication tools and the pros and cons for each of them.

 

Back in 2011 when I started working at CakeDC, we had an IRC server in place with a couple of plugins to retain messages for our day-to-day communication. Everyone used different clients like Colloquy on mac or Pidgin on Linux. Additionally, we used Skype for peer/team calls and also for client communication. In my opinion, the linux experience was awful until they improved the client a few years later. This setup was implemented in 2007 when the company was started, and in 2012, we decided to shut it down because it was easier just using Skype for everything, messages and calls.

 

 

After several years using - suffering - Skype, with new options in the market, we decided to move away to a more reliable and modern approach. The main reason was the lack of updates for Skype linux client, and the message retention limits. In 2016 we started utilizing the more than popular Slack and its open source alternative, Rocket Chat; always keeping Skype for client communication. 

 

Some months later the team concluded that Rocket Chat was the right choice, mainly because we wanted to have control over the messages and the information transmitted. Since the features we were using were available in both solutions, we installed our own Rocket Chat server. At this point I have to say that we did try the calls solution (Jitsy) inside Rocket Chat, but the experience was not good at all, issues with missing calls, poor call quality, etc, made us keep Skype for calls.

 

On the other hand CakePHP training was provided using Join.me and even when it worked very well in most situations; our trainer Jorge, always had to use a Windows machine instead of his usual Linux one. And then, Zoom emerged.

 

 

The year was 2018, when Zoom became so popular even though it started back in 2011 (yes, Zoom existed before COVID-19 crisis). We started using it and it quickly replaced Skype for our team calls. It allowed multiple people calls, screen share, etc. I must say, however, the Zoom chat is one of the worst things I have ever seen.

 

Going back to Jorge, as you can imagine he was very happy when he saw Zoom had a good Linux client. Unfortunately, he was quickly disappointed because the client screen crashed randomly, went black, and the computer ran out of memory when he tried to share his screen to more than 10 attendees. Happily he didn't throw his windows machine out of the window yet so he could continue giving the training with that machine.

 

It's 2020, COVID-19 is around us, and Zoom is probably the most popular telecommuting tool. For both adults and children, it is an essential tool to keep working and studying. However, fame never comes alone and threats, rumors and comments are making us move away (again) from Zoom to Google Meet. Also, it didn't make sense to pay for Zoom if we were already paying for GSuite. 

 

I didn't mention it before, but we have been using GSuite (former Google Apps) since the beginning. Google - late as usual - detected a market niche and decided to pump out its meeting tool. In my opinion, I am a standalone app person. This means that I will always prefer having 20 apps instead of 20 browser tabs. So, I don't like Google Meet a lot because of this, but I must say the call quality is superb. 

 

I am not sure how or when we will move to other tools, but right now we are very happy with our Rocket Chat installation and we are still getting used to Google Meet, but it fits our needs. 

 

As a side note we are still using skype to communicate with clients because it is the app everyone has, and sometimes people simply don't want to install something else or use something they are not used to.

 

 

To conclude I must say that each team and person should try all of these different tools before choosing one, because one tool that may fits my needs may not fit yours.

CakePHP Query Builder

CakePHP’s  database Query Builder provides a simple to use fluent interface for creating and operating database queries. It can be used to accomplish most database operations in your application, and works on all supported database systems.
Query builders allow us to create database queries that work with any supported database, without having to worry about differences between SQL implementations in the different database systems.


The CakePHP query builder uses PDO parameter binding to protect your application against SQL injection attacks. There is no need to clean strings being passed as bindings.
For creating a Query object in CakePHP, the easiest way is using find() from a Table object. In CakePHP, queries are lazily evaluated,  which means that they are not evaluated until any of the following actions happens: the query is iterated through a foreach, it’s called first(), all(), toList(), toArray(). 
You can check all the SQL queries that CakePHP is generating, you just need to enable the Database Logging. See here:  https://book.cakephp.org/4/en/orm/database-basics.html#query-logging
Let’s do a few samples using the Query Builder - this is the ER diagram of the database that we will be using for the queries. We have Orders, ProductsUsers and Items that will store the products sold in each order and the quantity sold. Let’s create some queries using the Query Builder SQL Functions: https://book.cakephp.org/4/en/orm/query-builder.html#using-sql-functions. SQL Functions as part of the Query Builder are abstractions of  some commonly used SQL functions,  and they allow the ORM to choose the specific implementation your application needs based on the Database that is being used. For example, CONCAT is implemented in a different way in MySQL and Postgres, using concat() function will work if you use MySQL or Postgres   Imagine we want to build a report of the products sold, including the following:

  1. Display the product in the following format “Products.name - Products.description”.
  2. Total of products sold.
  3. Total of products in stock..
  4. Total amount on sold products.
First, we need to build the Query object using find(), this needs to be done from the Table. $query = Table->find();. We want to get a report of the products sold and the current stock. Initially, we would need to build a subquery using ItemsTable where the information related to the products sold is present.  Don’t forget to use identifier() when referencing any column. This will tell us  the items sold per product. 

$itemsQuery = $this->Items->find() ->where(['Items.product_id' => $query->identifier('Products.id')]);

Now, let’s build each query needed for the information required:
  1. Let’s start displaying the  product in the following format: “Products.name - Products.description”. Using concat() we could get it: $query->select([             'display_name' => $query->func()->concat([                 $query->identifier('Products.name'), ' - ',  $query->identifier('Products.description')]),         ]);
  2. Total of products sold. Using sum() we could get it, we just need to sum Items.quantity per each product,  this  is why we use $itemsQuery and then we sum the quantity per each product. $query->select([
      'quantity_sold' => $itemsQuery->select(['sum' => $itemsQuery->func()->sum($query->identifier('Items.quantity'))]),
    ]);
     
  3. To get the income, we need to multiply the Quantity of items  *  Price  and sum all of them.    $query->select([
              'income' => $itemsQuery->select(['sum' => $itemsQuery->func()->sum($query->newExpr('Items.quantity * Items.unit_price'))
                ])]);
     
  4. Stock. to get the stock we need to take advantage of the quantity_sold we just got in #2, and subtract it from the real quantity Products.quantity. For getting this, we would need to create a subquery in the FROM clause using the previous queries, and then subtract in the target query something like quantity - quantity_sold. $products = $query->cleanCopy()->select([
                'id' => 'ProductDetails.id',
                'price' => 'ProductDetails.price',
                'quantity' => 'ProductDetails.quantity',
                'display_name' => 'ProductDetails.displaye_name',
                'quantity_sold' => 'ProductDetails.quantity_sold',
                'income' => 'ProductDetails.income',
                'stock' => $query->newExpr('ProductDetails.quantity - ProductDetails.quantity_sold'),
            ])->from([
              'ProductDetails' => $query->cleanCopy()->select([
                    'id' => 'Products.id',
                    'price' => 'Products.price',
                    'quantity' => 'Products.quantity',
                    'display_name' => $query->func()->concat([$query->identifier('Products.name'), ' -  ', $query->identifier('Products.description')]),
                  'quantity_sold' => $itemsQuery->select(['sum' => $itemsQuery->func()->sum($query->identifier('Items.quantity'))]),
                  'income' => $itemsQuery->cleanCopy()->select(['sum' => $itemsQuery->func()->sum($query->newExpr('Items.quantity * Items.unit_price'))]),           ])
        ]);
     
Notice that we are using cleanCopy(), this is useful when the same Query object is affected previously by a select(), from() or where clauses, if you run this same example without using cleanCopy() you will get unexpected results.  The SQL query generated is this: SELECT ProductDetails.id AS id, ProductDetails.price AS price, ProductDetails.quantity AS quantity, ProductDetails.display_name AS display_name, ProductDetails.quantity_sold AS quantity_sold, ProductDetails.income AS income, (ProductDetails.quantity - ProductDetails.quantity_sold) AS stock FROM (SELECT Products.id AS id, Products.price AS price, Products.quantity AS quantity, (CONCAT(Products.name, :param0, Products.description)) AS display_name, (SELECT (SUM(Items.quantity)) AS SUM FROM items Items WHERE Items.product_id = (Products.id)) AS quantity_sold, (SELECT (SUM(Items.quantity * Items.unit_price)) AS SUM FROM items Items WHERE Items.product_id = (Products.id)) AS income FROM products Products) ProductDetails
CakePHP QueryBuilder gives a ton of possibilities to create queries with clean and robust code. So go play with it and enjoy!

The Making of a Marketing Plan

Listen, although 2020 felt like it lasted 25 years, it’s still hard to believe that we are wrapping up this roller coaster of 12 months.  As companies prepare for 2021, crossing their fingers and wishing for a better Q1… it is important to start thinking about marketing strategies and plans for the next year. Without ideas and a solid goal for your company, it is very unlikely that things will change.   Reasons that making a marketing plan is important:  1. It organizes your goals and provides clear plans of actions to achieve them  2. It keeps everyone on track and on the same page  3. Promotes motivation and accountability
  I know making a marketing plan can sound time consuming, and a little complex, but it doesn’t have to be! I am going to walk you through the steps of making clear cut goals and plans for 2021 (with some actual examples!).  

1. Brainstorming

Our team is great at making notes of things that need attention, whether it's good or bad. We keep open lines of communication on things that are going well, or may need some extra work. It is important for everything to bring their ideas together, no matter how big or small.  I suggest keeping a notepad with things / ideas you have for your team moving forward, and organize them in a way to present to your marketing team.  

2. Team meeting

Now it is time for a group session to compare ideas, talk about what should be the priorities and get approval on anything needed. These meetings are super beneficial, because it is always refreshing to see if your team’s ideas mimic yours, or perhaps they even have some additional great ideas.   

3. Start building your plan

There are ample amounts of templates and checklists that you can find online to ensure that you’re including important information on your strategy plan. Some of the things I recommend including are:
Of course your main table of contents - easy to view for your team     Company mission - WHO ARE YOU?  
  Product Overview - what are you offering your clients?     Goals / Challenges - we all have them, don’t be shy  

Target market - Who are you working for?       Expansion Plan - how will you make it to the next level?   Upcoming Actions - Making a clear timeline for the next year. It is important to make the timeline obtainable... in other words, don’t make goals that are impossible to meet.   Other important topics include additional small actions, goal timeline, campaign calendars, advertising outlets, social media platforms (and the importance, utilization for each one).  

So making a powerpoint or pdf presentation for your team will allow all of the ideas and goals  to come together and be available in one place. I am a big checklist type of person, so in addition to my marketing plan, I always create a document.   

4. Create a spreadsheet

A spreadsheet doesn't have to be fancy, but it holds the team accountable, and we are able to make notes so that we can track the status of certain actions. This also helps me stay on track, and know what actions need to be executed next.    Something like this for internal works just fine:  
 

5. Budget & Execution 

It is extremely important that your team supports the marketing efforts. It is also important to know what your marketing budget will allow. Will you have additional funds for new goals? Will you need to reduce funds on other outlets to allow for new ideas? These are things that will need to be discussed with your financial department.   This is a good reason to create a marketing metrics / budget spreadsheet to track these items. I will share my examples on this in a future blog.    So, once your team is on the same page, and they have clear goals…. IT’S GO TIME. Start working on your plan of actions and preparing to let them fly. For us, some of our goals will take some prep work, so we are gearing up in Q4. 
  Hopefully, you have helpful ideas that you implement on your marketing plan… maybe it’s something I haven’t thought of (i’d love to hear yours! Email me - amanda.goff@cakedc.com). Either way, I wish everyone good luck on their strategies, and may all of your goals come true in 2021. If you’d like more insight on any of the ideas I have included, feel free to reach out, I’d be happy to chat!
