bookmark_borderThe current state of things

It’s amazing how life gets going in a rhythm, and you get your head down and working so hard, that you sometimes forget to look around (or in this case, write in your blog).

Working at a small travel advertising company is a really great thing – until almost all travel ceases, and no one is advertising, and you suddenly find yourself unemployed as a result.

So today I am taking a moment to reflect on what I’ve learned in the last few months. One of my projects gave me the opportunity to work with Vue.js for the first time, and I basically taught myself what I needed to know in order to get it done. It was a good challenge, and I learned a lot.

Mixed in with that I was trying to find a way to query data for a reporting tool that involved millions of rows of data, which was being used by the sales team. The tool already worked, but our team was trying to find a better way to run the queries so they didn’t take up to several minutes to run. We were dealing with behavioral data, and there was a lot of it. The dynamic nature of the queries meant that the more conditions you added, the slower the query might run. Along with that I was trying to normalize the way the data was represented so that other types of queries could all be run the same way, and even be mixed together. Talk about a complex problem! But we were making some headway with it, and then the corona virus hit. We went from a growing thriving company to zero income in two weeks.

The other technologies I was working on were crossfilter.js, dc.js, and d3.js. I did video courses on each, and got to mess around with them a bit using real data from our system, although I wasn’t ready to actually do any graphing just yet. I knew where I wanted to put them eventually, but that was further down the development roadmap.

I guess now, I’ll just need to find a way to work with these in some personal projects to improve my skills, and keep them sharp.

 

bookmark_borderPHPStorm – Stop those accidental tab closures!

If you’re like me, you have probably had this happen. You go to click on one of the many tabs you have open in PHPStorm, only to accidentally click the X, and close it. ARGH!

Today I found a way to alleviate that pain. You can turn off the X!

  1. Under Preferences, search for Editor Tabs
  2. Locate Close button position:
  3. Set it to None

Now, to close a tab, you must either hit the keyboard shortcut, or right-click it. Either of those will be a deliberate action.

bookmark_borderDefensive Programming | Laravel find()

  • Defensive Programming

One of the things I’ve learned in my career is to code defensively.

Laravel makes it very easy to ask for an object, but it also makes it very easy to get it wrong. If you request an object using the find method and it doesn’t find it, you don’t get an error. You get a null. If you then request a property on that object, without first checking for a null, you will get a run-time error.

This is pretty basic stuff, but it never hurts to go over it again.

Wrong:

$name = Widget::find(23)->name;

 

 

Right:

if ($widget = Widget::find(23)) { $name = $widget->name; }

 

 

The first block will throw an error if Widget #23 doesn’t exist in the database. The second checks for it’s existence and then only reaches for the name if it found it.

I have been programming for almost 20 years. It all started with Basic and RPG III way back in high school, and have played around with many languages. PHP is my main language today.
