Convert pixel-art-style images from LLMs into true pixel resolution assets
https://www.reddit.com/r/programming/comments/1lxqrbj/convert_pixelartstyle_images_from_llms_into_true/
<!-- SC_OFF -->I created an algorithm that turns pixel-art-style outputs from LLMs such as GPT-4o into usable assets. GPT-4o has a fantastic image generator and can turn images into a pixel-art-like style. However, the raw output is generally unusable as an asset due to High noise High resolution Inconsistent grid spacing Random artifacts Due to these issues, regular down-sampling techniques do not work, and the only options are to either use a down-sampling method that does not produce a result that is faithful to the original image, or manually recreate the art pixel by pixel. Additionally, these issues make raw outputs very difficult to edit and fine-tune. I created an algorithm that post-processes pixel-art-style images generated by GPT-4o, and outputs the true resolution image as a usable asset. It also works on images of pixel art from screenshots and fixes art corrupted by compression. If you are trying to use this and not getting the results you would like feel free to reach out! <!-- SC_ON --> submitted by /u/Ok-Championship-5768 (https://www.reddit.com/user/Ok-Championship-5768)

TUI for Alias Management with Command Usage Tracking and Smart alias suggestions
https://www.reddit.com/r/programming/comments/1lyk875/tui_for_alias_management_with_command_usage/
<!-- SC_OFF -->Hey everyone, I built alman (alias manager) a command-line tool and TUI designed to make alias management easier, by using a cool algorithm to detect commands in your terminal workflow which could benefit from having an alias, and then intelligently suggesting an alias for that command, thereby saving you time and keystrokes. Here is the github : https://github.com/vaibhav-mattoo/alman Alman ranking algorithm Alman ranks your commands based on: Length: Longer commands get a slight boost (using length^(3/5) to avoid bias). Frequency: Commands you use often score higher. Last use time: Recent commands get a multiplier (e.g., 4x for This ensures the most useful commands are prioritized for alias creation. It then generates intelligent alias suggestions using schemes like: Vowel Removal: git status → gst Abbreviation: ls -la → ll First Letter Combination: docker compose → dcompose Smart Truncation: git checkout → gco Prefix Matching: git commands → g + subcommand letter Some of its features are: Interactive aliases for browsing adding and removing aliases. Ability to track your aliases across multiple shells and multiple alias files. Command-line mode for quick alias operations. Cross-platform: Works on Linux, macOS, BSD, and Windows (via WSL). Alman offers an installation script that works on any platform for easy setup and is also available through cargo, yay, etc. Try it out and streamline your workflow. I’d really appreciate any feedback or suggestions, and if you find it helpful, feel free to check it out and star the repo. <!-- SC_ON --> submitted by /u/YboMa2 (https://www.reddit.com/user/YboMa2)

Study finds that AI tools make experienced programmers 19% slower. But that is not the most interesting find...
https://www.reddit.com/r/programming/comments/1lxh8ip/study_finds_that_ai_tools_make_experienced/
<!-- SC_OFF -->Yesterday released a study showing that using AI coding too made experienced developers 19% slower The developers estimated on average that AI had made them 20% faster. This is a massive gap between perceived effect and actual outcome. From the method description this looks to be one of the most well designed studies on the topic. Things to note: * The participants were experienced developers with 10+ years of experience on average. * They worked on projects they were very familiar with. * They were solving real issues It is not the first study to conclude that AI might not have the positive effect that people so often advertise. The 2024 DORA report found similar results. We wrote a blog post about it here (https://blog.nordcraft.com/does-ai-really-make-you-more-productive) <!-- SC_ON --> submitted by /u/Livid_Sign9681 (https://www.reddit.com/user/Livid_Sign9681)
