Put that right Command key to good use

Hold down ⌘ command and press the first letter of the app name to focus apps instantly.

When pressing the key while the app is already focused, you can choose to hide the app or cycle to the next app with the same first letter.

Assign custom keys for your favorite apps

Hold down ⌘ command + ⌥ option and press any letter to assign that letter to the currently focused app.

When an app is in the static list:

  • the assigned key can launch the app when it isn't running
  • the Hide/Cycle setting can be adjusted on a per-app basis.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

    A useful productivity tool

    rcmd is something that could potentially turbocharge your productivity. However! you will need to get used to using it.

    My only issue is that I forget about it ¯_(ツ)_/¯

  • What's new in Claude Fable 5.1
    It took every string including the ones I already rewrote by hand, and proposed even more weird LLM speak. Like for _Left Command conflict detected_ it proposed _This keyboard can't tell left from right_. It's a very capable coding agent, but I can't understand how it can be so bad at writing.

  • Show HN: I built a grouped app switcher for macOS
    I downloaded. This looks like an interesting alternative to rcmd (https://lowtechguys.com/rcmd/). Will future updates cost? - Source: Hacker News / 12 months ago
  • Show HN: I built a tool to solve window management once and for all
    Funny, this sounds like a good idea, but I'm quite happy with the exact opposite: I use rcmd[1]. I hold down the right command key and press the first letter of the window name to switch to it. I can override this dynamic mapping by pressing right command + option + , so I have an IM client on I, for example. It means I never have to remember/guess how command+tab works (although I had fewer issues with... - Source: Hacker News / about 1 year ago
  • Mac browser Arc being discontinued in favor of new Dia app
    Might not meet your needs but I had similar issues and found an app called rcmd, it lets me easily bind keybinds to my commonly used apps, and you can also easily toggle between multiple windows of the same app via the keyboard https://lowtechguys.com/rcmd/ - no affiliation, and probably other similar options are available. - Source: Hacker News / over 1 year ago
