This 3KB notepad app shows exactly why modern Windows is so bloated

Dave Plummer, known for creating the Windows Task Manager, discusses software bloat in a recent video, highlighting his compact notepad application, Tiny Retro Pad, which is only 2,686 bytes. He notes that while modern applications require higher specifications due to increased complexity, the lack of optimization in code has led to performance degradation. For example, Windows 10 required 1GB of RAM for its 32-bit version, while Windows 11 requires a minimum of 4GB. Plummer emphasizes the importance of efficient coding practices and critiques the tendency of modern software to include unnecessary components, suggesting that prioritizing efficiency could improve user experience on platforms like Windows 11.

“Not every app needs to bundle the universe”: This tiny notepad app shows why Windows has become so bloated

Dave Plummer created a notepad application called Tiny Retro Pad, which is 2,686 bytes in size, contrasting with larger modern software. The application mimics the original Microsoft Notepad without contemporary features. Plummer emphasizes the importance of working within constraints, recalling a time when developers had to focus on efficiency due to hardware limitations. He utilized existing resources within the Windows ecosystem to maintain the compactness and functionality of Tiny Retro Pad.

Ex-Microsoft engineer rebuilds Notepad in 2.5KB using nothing but stuff Windows already had

Dave Plummer, a retired Microsoft engineer, has developed TinyRetroPad, a Notepad-like application that is only 2.5 kilobytes in size. TinyRetroPad includes features such as Open, Save, Find and Replace, printing, font selection, word wrap, and an unsaved changes prompt. It is built on existing Windows components, allowing it to function efficiently without extensive resources. TinyRetroPad is based on Dave’s Tiny Editor and utilizes RICHEDIT50W for text handling. The application's file size increased incrementally with each feature added, with the final size being 2,476 bytes. Crinkler, a compression linker, was used to optimize the executable. TinyRetroPad is still in development, facing issues like high memory consumption and compatibility problems. In contrast, Windows 11's Notepad has become larger and more complex, weighing approximately 352KB and incorporating features that some users find unnecessary. Windows 11 LTSC retains the classic Notepad without modern features, while TinyRetroPad aims to demonstrate the potential for simplicity in application design.

Ex-Microsoft engineer rebuilds Notepad in 2.5KB using nothing but stuff Windows already had

Dave Plummer, a former Microsoft engineer, is recreating Notepad in 2.5 kilobytes with a project called TinyRetroPad, which includes features like Open, Save, Find and Replace, printing, font selection, word wrap, and unsaved changes prompt. TinyRetroPad leverages existing Windows infrastructure, utilizing built-in resources to function efficiently. It is based on Matt Power’s Dave’s Tiny Editor and operates as a wrapper around RICHEDIT50W. The size of TinyRetroPad increased with each feature added, reaching 2,476 bytes with printing. The project uses Crinkler, a compression linker, to optimize the executable. TinyRetroPad currently lacks a dedicated Releases page and may trigger false positives from antivirus software. Users have reported issues such as excessive memory usage and compatibility problems with older Windows versions. In contrast, the modern Notepad in Windows 11 has grown to approximately 352KB, with a total disk footprint nearing 5MB, leading to user backlash over its complexity. Windows 11 LTSC retains the classic Notepad, while TinyRetroPad aims to demonstrate the potential of leveraging existing OS capabilities rather than adding unnecessary features.

‘Pure old-school Windows’: Ex-Microsoft engineer shrinks down Notepad to 2.5 kilobytes with ‘no bloat, no telemetry, no nonsense’

A former Microsoft software engineer, Dave Plummer, has launched TinyRetroPad, a minimalist text editing application designed as an alternative to the increasingly complex Notepad. TinyRetroPad is a fork of Tiny Editor, which was based on Plummer's earlier project, HelloAssembly. The application aims to provide a simple and efficient user experience, reminiscent of earlier Windows versions, by utilizing existing Windows components to maintain a small footprint. Users have expressed dissatisfaction with Notepad's growing complexity, prompting a search for lightweight alternatives. TinyRetroPad offers a compact interface without unnecessary features or telemetry.

Former Microsoft engineer shrinks Notepad down to size

Dave Plummer, a former Microsoft engineer, has created TinyRetroPad, a minimalist text editor that is only 2.5 kilobytes in size. It aims to provide a simple text editing experience, reminiscent of older software like Notepad, which has become bloated over time with unnecessary features. TinyRetroPad includes essential functions such as Open and Save As dialogs, font selection, and printing capabilities, while using assembly language and the RICHEDIT50W from the WinAPI. The application requires more system resources to run effectively but focuses on maintaining lean code and binaries.

Microsoft once used its own brand of ‘Lego’ to optimize Windows

Former Microsoft engineer Dave Plummer reflected on software performance challenges during the '90s, specifically the limitations of machines with 12 MB of RAM. He discussed the Basic Block Tool (BBT), which optimized software binaries by reorganizing their structures to enhance execution speed. A typical binary contained around 10 MB of code, but only about 300 KB was necessary for startup. If this essential code was scattered, it led to performance degradation due to excessive page access. BBT defragmented binaries, grouping related code to streamline access and improve user experience, particularly for large products like Windows and Office. Modern tools like BOLT and HP's Dynamo continue to optimize binary layouts and runtime code, but Plummer cautioned about the risks of manipulating binaries. He noted that while computational power has increased, modern software faces similar performance challenges, with larger binaries and complex dependency graphs. He emphasized the importance of locality in software design, advising to keep hot data and code together to enhance performance.

I just found out the creator of Windows Task Manager accidentally left his phone number inside the app

Dave Plummer, the creator of the original Task Manager at Microsoft in the 1990s, encountered an issue where CPU utilization readings occasionally exceeded 100%, which he suspected was a bug in the kernel. Despite being a user interface designer and facing skepticism from the kernel team, he implemented 'asserts' in the code to diagnose the problem. One assertion specified that CPU usage should not exceed 100%, and he embedded his name and home phone number in the code for anyone who might encounter the issue. No one ever contacted him about the bug, and it remained unresolved until the kernel developers identified and fixed it later.

‘A performance tool that requires a graduate seminar before breakfast has already lost the room’: Why Windows Task Manager looks like it’s getting CPU usage wrong

Users have expressed frustration with Windows 11's Task Manager CPU usage reporting, believing it relies only on base clock speeds. Dave Plummer, the original architect of Task Manager, indicated that discrepancies may arise from average calculations and inherent compromises in the metrics. In response, Microsoft announced a fix in a recent Preview build, stating that Task Manager will now use standard metrics for CPU utilization across all pages to align with industry standards. Plummer also suggested a distinct Windows mode for power users to enhance flexibility.
