An alphabet is any set of finite symbols such as a and b. For example, the alphabet Σ = {a, b} is an alphabet that contains the strings that can be built by combining a and b and the alphabet Σ = {0, 1} is the an alphabet that contains the strings that can be built by combining 0 and 1. Symbols such as a and b put together to form something like bbaa are called strings. ...

Dagger is a programmable CI/CD engine that runs your pipelines inside containers1 which makes it easier to test things locally and to setup complex workflows. Not having to write yaml/bash/etc as the workflow gets more complex is a huge advantage for me. I’m working on a personal project that will allow people to deploy their code by selecting a GitHub repository. Me and a friend have decided to use Dagger to clone the user provided Git repository and build a Docker image and it was extremely easy to get it working. ...

It feels like most people are not used to thinking about how things can fail, programming as if things always work as expected is the default modus operandi of most engineers i have talked to. Some examples that come to mind: http requests without handling responses that don’t have status 200, no timeouts, no retries, publishing a message to kafka and them updating a database, having a web client orchestrate a transaction across several systems without thinking: what if the user closes the browser tab? ...

A deadlock happens when there’s at least one resource that can be only acquired by one process at a time and there’s a process P1 that is waiting to acquire a resource currently held by a process P2 and P2 is waiting to acquire a resource currently held by P1. The word process does not mean we are talking about just OS processes. There are two processes: Process A wants to acquire a lock on resource 1 and then a lock on resource 2. Process B wants to acquire a lock on resource 2 and then a lock on resource 1. ...

Anomalies An anomaly or read phenomena can happen when a transaction reads data that may have been modified by another concurrent transaction. Dirty read A dirty read happens when a transaction T1 reads data that has been modified by a concurrent transaction T2 that has not has been committed or rolled back yet. T1 ends up working with stale data if T2 does not commit. T2 starts executing and sets x to a new value, T1 starts executing and reads x, the value of x is the value just set by T2, T2 rolls back, the value of x is not persisted to the database but T1 will move forward with the stale value of x that was written before T2 rolled back. ...

The problem You are developing an application backed by a database, something happens and then several of your users try to access the same content. Several requests are sent to your backend at almost the same time and your backend hits the database once for each request to fetch the same data. Fetching the data only once If N requests asking for the same data arrive at the backend at around the same time, the backend could hit the database to fetch the data when the first request arrives and force the other requests to await until the data is fetched. When a response to the request sent to the database arrives at the backend with the data, the data can be shared with the requests that are waiting for it. ...
