Empty Enter Expander – Type less in the terminal with this tool
When you have a lot of aliases it can be difficult to remember how was the one you need named especially if you do not use it very often. You can also have files stored in a bin folder and look there to find the name. Another trick is to prepend your commands with a comma then type the comma and hit the Tab key to see only your own commands. There is an article about it somewhere on the Internet. I needed something lightweight to always show me the available commands. Something to run with a few keystrokes. Something that stores commands in files and folder structures. The idea was born at…
In plain words
Empty Enter Expander is a lightweight terminal tool that helps users quickly access and run custom commands and aliases. It stores commands in files and folder structures, allowing users to view available options with a few keystrokes rather than memorizing numerous aliases. The tool can launch applications, expand text from templates, and automate predefined tasks, making it useful for developers and power users who frequently work in the terminal.

In the maker’s words, at launch
When you have a lot of aliases it can be difficult to remember how was the one you need named especially if you do not use it very often. You can also have files stored in a bin folder and look there to find the name. Another trick is to prepend your commands with a comma then type the comma and hit the Tab key to see only your own commands. There is an article about it somewhere on the Internet. I needed something lightweight to always show me the available commands. Something to run with a few keystrokes. Something that stores commands in files and folder structures. The idea was born at the time of using Linux Debian with the dwm (dynamic window manager). The first version was implemented in bash and it could do three things: start an application, expand text from a template and do a predefined automation on the selected application. It was launched by a keyboard shortcut and opened the list of commands in a new terminal window. The commands were stored in nested folders and it was able to switch between the three modes (launcher, expander, automator). It also required only few keystrokes to do the desired action. For instance, I was in the terminal and hit Ctrl+P. It opened a new terminal and listed applications to launch. I hit the Space to switch to the expander mode. Then I hit the g to enter the Git folder and s for the status. The result was that it put the git status to the terminal I was in before. This expander could be used in any application. It could insert the email template into the browser. Then I migrated to macOS and really missed that tool. So I quickly wrote a zsh vesrion that consists only the expander mode and supports only the terminal. It is activated by hitting Enter on empty command and then it inserts the desired command right into the prompt. For example, when you hit Enter, g and s you will get the git status command to the prompt and you can then execute it with Enter. Of course, those commands and keys are defined by you. There are various and lenghty commands that I use on a daily basis like this and it saves a lot of typing. The tool is called Empty Enter Expander. It is implemented for the zsh as of now.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
