Async standups: Pros, cons, do they make sense for you?

Daily standups have been a core element of software development but come at a cost of time, leading to an exploration of asynchronous standups as an alternative.
Asynchronous standups involve written updates on a dedicated channel instead of daily meetings, resulting in boosted productivity and relevant updates.
Benefits of asynchronous standups include improved productivity, concise updates, and fewer meetings, but challenges like updates becoming noise and decreased team morale arose over time.
A middle ground approach with daily meetings on specific days and async updates on others helped solve some challenges but highlighted the importance of human interaction and team morale.
The experiment showed that while asynchronous updates may work for some teams, the lack of daily synchronous touchpoints can impact morale, leading to a preference for fewer standups overall.
Asynchronous communication is considered more efficient, but excessive async communication may be overwhelming, necessitating a balance between async updates and synchronous interactions based on team dynamics and context.
The decision on whether async standups make sense depends on the team's collaboration needs, with a suggestion that they may be more suitable for teams that don't work closely but need regular updates.
In conclusion, the effectiveness of async standups varies based on the team's context, and trying it out can provide insights into team dynamics and communication preferences.
Experimenting with different meeting approaches can lead to finding the optimal balance between async and synchronous communication methods for improved team efficiency and morale.

How to Use SQL in Go

Learn how to use SQL in Go (Golang) using SQLite including connecting to a database, writing queries, creating tables, CRUD operations, and handling context and timeouts.
To set up the project, initialize with 'go mod init sql-in-go' and install SQLite using 'go get -u github.com/mattn/go-sqlite3'.
Connecting to the database involves using sql.Open function with the driver name and database file path, checking for errors, and closing the connection after use.
Common database operations include creating, inserting, querying, updating, and deleting data with corresponding SQL queries.
Creating OrderRepository and Order structs allows for defining methods to interact with the database like creating tables, inserting data, and retrieving orders.
It is essential to use placeholders instead of concatenating strings to avoid SQL injection while inserting data into the database.
Context and Timeout can be used to set deadlines for query execution to avoid blocking the database connection for too long.
The tutorial provides practical code examples for creating tables, inserting and retrieving data, updating, and deleting records in SQLite database using Go.
By following this tutorial, you can effectively work with SQL databases in Go and efficiently manage data operations.
The code snippets provided demonstrate how to perform various database operations utilizing the SQL capabilities in Go with SQLite.
