What is Hatchet?

Hatchet replaces difficult to manage legacy queues or pub/sub systems so you can design durable workloads that recover from failure and solve for problems like concurrency , fairness , and rate limiting . Instead of managing your own task queue or pub/sub system, you can use Hatchet to distribute your functions between a set of... See more

Using feature flags

It's always a good idea to put new features behind a feature flag.

This contributes to a rollout strategy that can surface user feedback in a much more contained and safe environment.

When thinking about how to rollout a new feature to users, first think about your peers. Many of the Resend team members also use Resend on their... See more

Hopefully, at this point, you see where I’m going with this. What I’ve concluded, based on experience, is that positioning your project as an alternative implementation of something is a losing proposition. It doesn’t matter how smart you are. It doesn’t matter how hard you work. The problem is, when you build an alternative implementation, you’ve... See more

Problem : Tight coupling leads to fragility - a change in one microservice breaks connected services.

Low cohesion results in unclear responsibilities.

• Solution : Apply loose coupling and high cohesion. In a loosely coupled system, each component is independent and changes in one will not affect the others. High cohesion means that each component

When a test fails, you should be able to begin investigation with nothing more than the test’s name and its failure messages —no need to add more information and rerun the test.

Effective use of unit test frameworks and assertion libraries (JUnit, Truth, pytest, GoogleTest, etc.) serves two important purposes. Firstly, the more precisely we express... See more

Your job involves turning the unknown into the known and translating vague ideas into actionable plans. This often involves a blend of:

• Detective work — ask the right questions, collect evidence, build a case theory, validate it


• Isolating uncertainty to the smallest components and proving / disproving theories


• Divide and conquer — breaking down the

Here's a list of those log levels from lowest precedence to highest:

notset (0) - Indicates that ancestor loggers should be consulted for the log level or that all events are logged (default setting)

debug (10) - Detailed information that would be of interest to the developer for diagnostic purposes

info (20) - Information that confirms that your... See more

factory_boy

factory_boy is a fixtures replacement based on thoughtbot's factory_bot.

As a fixtures replacement tool, it aims to replace static, hard to maintain fixtures with easy-to-use factories for complex objects.

Instead of building an exhaustive test setup with every possible combination of corner cases, factory_boy allows you to use objects... See more
