Task Tracker

Stopwatch Task Tracker

The application is a simple stopwatch task tracker built using the Tkinter library in Python. It was tested in Python 3.10.11. It has the following features:

Display

When the application is first opened, it displays the initial time as 00:00 at the top of the window. The title of the window is set to "Stopwatch task tracker".

Task Name Input

In the middle of the window, there's a label "Task Name:" to the left of a text input box where users can enter the name of their task.

Run local LLM OpenAI Compatible Inference Server (llama.cpp)

Here I describe how to quickly get set up with a local LLM OpenAI compatible inference server.

Install Docker (RHEL 7)

Docker is a prerequisite. Complete the following instructions to set up docker

dc-user@devcloud$ sudo yum update
dc-user@devcloud$ sudo yum install -y yum-utils

Oobabooga with LLM on CPU

Here I describe how to quickly get set up with Llama-2-7B model trained with chat data using Docker. Below instructions launch Oobabooga container which includes an inference server and front-end web application for interactive chat. These instructions avoid requirements for Nvidia GPU.

Install Docker (RHEL 7)

Docker is a prerequisite for running Oobabooga. Complete the following instructions to set up Docker.

dc-user@devcloud$ sudo yum update
dc-user@devcloud$ sudo yum install -y yum-utils
dc-user@devcloud$ sudo yum-config-manager --add-repo http://yum.oracle.com/public-yum-ol7.repo
dc-user@devcloud$ sudo yum-config-manager --enable *addons

Android Bookmarklet - Reader View (Simplified Page)

Android Bookmarklet - Reader View (Simplified Page)

In chrome on android the "Simplified Page" feature does not have a button. If for some reason the browser decides not to display the layover toast message to access this feature, then the user is unable to enter "simplified view". The solution to this problem has been discussed before on Stack Overflow here, where they suggest opening a url to access a local resource on the browser cache. The local resource URL is formatted as follows:

chrome-distiller://<UUID>_<HASH>/?url=<URL>

It is not permitted to perform a javascript redirect to a local resource in the browser, however it is possible to display the URL as text.
