New Show Hacker News story: Show HN: Xzgrep is twice as fast with dash versus bash

Show HN: Xzgrep is twice as fast with dash versus bash
2 by chasil | 4 comments on Hacker News.
In the CentOS world, a shell script written by "Charles Levert" has been extended as the compressed grep for (gzip/bzip2/xz) as /bin/(zgrep/bzgrep/xzgrep); variants of this script are bundled in their respective packages. The dash shell, available in EPEL for CentOS, appears to specifically speed up xzgrep considerably when altered from #!/bin/sh to #!/bin/dash. In my testing on a 32-bit platform under xargs, a search of 14k files of 20M total size runs in half the time. Do others see this performance increase? Is this another tangible benefit for Debian/Ubuntu moving the system shell from bash to their Almquist shell derivative?

New Show Hacker News story: Show HN: Natural language Twitter search using Codex

Show HN: Natural language Twitter search using Codex 3 by andyk | 0 comments on Hacker News. We built a structured search engine for Twitter called Bird SQL, available at https://ift.tt/7BU0hHb . Our search interface uses OpenAI Codex to translate natural language to SQL. Our backend then verifies the SQL, executes it, and displays the results on the web app. This makes large structured datasets like a scrape of Twitter easy for anyone to explore. As background, while working on text-to-SQL as a general problem, we came to believe one of its most powerful applications is as a search tool because: - SQL is hard to write by hand and prone to errors - It allows you to iterate quickly if you’re exploring a new dataset - A lot of contextual information that you’d normally have to internalize (e.g. your data’s schema) can be automatically generated and offloaded to the language model Using large language models (LLMs) like Codex to write the SQL for you means you don’t have to worry about

New Show Hacker News story: Show HN: Movis – A Video Editing Library in Python

Show HN: Movis – A Video Editing Library in Python 2 by rezoolab | 0 comments on Hacker News. Originally, this library was created due to my motivation to make videos in Python. Of course, I considered other Python libraries, but I decided to create a new library for video editing because I needed the following features and also for study purposes: - The existence of composition. Especially, the ability to perform advanced video editing by inserting compositions within compositions. - The ability to add animations based on keyframes. - Effects like chroma key and drop shadow. - A caching mechanism to render the same frame quickly. - Various blending modes. These features, despite being standard in proprietary video editing software, were not present in previous Python libraries. Currently, I am using this library to automatically generate videos from raw materials. I would be grateful for any comments, thoughts, or requests.
