<p>Even though the order of how containers starts can be controlled through <code>depends_on</code> and container order in docker-compose.yml, compose won't really wait until a container is ready before starting the next one. If you don't want to deal with it at application level, there are some other paths you might try: </p>

<p>The Wrong Abstraction • <em>duplication is far cheaper than the wrong abstraction</em> • Existing code exerts a powerful influence. Its very presence argues that it is both correct and necessary. We know that code represents effort expended, and we are very motivated to preserve the value of this effort. And, unfortunately, the sad truth is that the more complicated and incomprehensible the code, i.e. the deeper the investment in creating it, the more we feel pressure to retain it (the "sunk cost fallacy").</p>

<p>The law of large numbers: the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer to the expected value as more trials are performed.</p>

<p>numpy has a really handy function called <code>is_busday</code> to check whether a given date is business day or not, it also can receive a list of parameters to give this functionality a power boost such as weekmask (if you need a custom definition for weekdays) and holiday calendar </p>

<p>Eslint-stats: Analyses JS files for error frequency, rather than location. This is helpful when introducing ESLint to an existing project. </p>

<p>You don't need a hacky snippet to manipulate dates into the a specific moment, such as EOD. <code>datetime.datetime.combine</code> can do that for you as it receives three parameters: <code>date</code> (can be <code>datetime</code> too), <code>time</code> and <code>tzinfo</code> , the latter being an optional argument. The following snippet will put a given date into EOD:</p> <p>``` from datetime import datetime, time</p> <p>date = datetime.strptime("2019-01-01", "%Y-%m-%d") # datetime.datetime(2029, 1, 1, 0, 0) eod_date = datetime.combine(date, time.max) # datetime.datetime(2029, 1, 1, 23, 59, 59, 999999) ```</p>
