Recently, one of the clients reported that, while using our app for appointments and work schedule – they lost one of the working days. Client’s worker was supposed to work on the 31st of December 2019.
Firstly, working on the 31st is an achievement. Since we can’t affect it, “bug report” was filled on our end. After few hours of debugging, the problem was found.
Cake\I18n\Time class to handle date time. It’s an ancestor of
chronos library under the hood. As a result, when you’re working with DateTime object, the formatting slightly changes. Thankfully, I was not the only one who accidentally used “year” notation wrong.
use \Cake\I18n\Time; $badDayToWork = '2018-12-31 09:00:00'; $time = new Time($badTimeToWork); print_r($time); /* output: Cake\I18n\Time Object( [time] => 2018-12-31T09:00:00+02:00 [timezone] => Asia/Nicosia [fixedNowTime] => ) */ print_r($time->i18nFormat('YYYY-MM-dd HH:mm')); // Output: 2019-12-31 09:00.
One tiny bit I missed was incorrect “Y” formatting flag.
|YYYY (year of “Week of Year”)||2019|
In this case, 2018-12-31 falls on Monday, so according to ICU documentation – it’s year 2019.
Among numerous metrics on code evaluation (like CRAP index) in product lifecycle, code churn seems to be the one to look for while dealing with post-release and legacy code elimination.
Code churn helps you to evaluate file changes across builds.
Code churn is a good predictor of post-release defects. Thus, it’s a warning sign if you approach a deadline while your code churn increases. That’s a sign that the code gets more and more volatile the closer you get to your deadline. You want the opposite. You want to stabilise more and more code the closer you get to delivery.Codescene
Code Churn features
One of the features of code churn – is bottleneck finding across developers and tasks. Low commit rates per author can signal the management, that there’s some sort of problem going on:
- Task ambiguity that prevents to complete the task, indecisive stakeholders
- Technical issues within the platform, preventing on completing the task
- Legacy code that remains in the product, and possible technical debt increase
Ben Thomson in his post about code churn, provides few graphs, illuminating code impact on productive/churn code across release cycle. As an example, I’ve used CodeScene service, to test code churn on one of the plugins I’ve worked a lot back in the days (hopefully will have time to get back to it soon) – cakephp-calendar.
As we can see, March-April was a major rewrite of the plugin, that followed next spike occurring in July. March re-write made the code more fragile. If we dig deeper, we can see that an overall complexity of March-April release was drastically decrease. Here’s one of the examples:
It’s still quite high, but it’s nothing comparing to what it was. Still, the code was in semi-prototype mode.
Here’s an example of creating Dashboards with GraphQL and ElasticSearch from React community.
As a big fan of VueJS framework, it’s still nice to check what’s happening on the other side of the fence from React community fellow coders.
Mitch Clay published an article on how you can utilise GraphQL with ElasticSearch to design dashboards for the your projects.
The stack is pretty common for JS environment:
- GraphQL with Apollo
But, the only bit I missed using – ElasticSearch engine, as more and more projects use it – it seems that I need to give it another look.
AdminLTE is by far one of the great examples of what Bootstrap CSS can do and consists of pre-defined UI elements used for Admin control panels. Similarly we have ElementUI, Bulma, and Bootstrap CSS in its core.
Right now, there’s a massive amount of various admin panels on the net.
So, I made a quick Proof of Concept on how we can easily convert default AdminLTE layout into a dark theme, with a bit of help from
AdminLTE Midnight Dark Theme is available on GitHub. I added a detailed description on how to run it in dev mode via AdminLTE repository.
You might find it useful to go through customisation instructions first.
