Because FileAge depends on a valid last-write timestamp, files without that timestamp are incorrectly reported as missing. The underlying failure is also not checked for its error code. ### Source excerpt In addition to using an ancient development environment, with terrible UX, Greta also has the misfortune of working in Pascal. Recently, she was diagnosing a bug. The program was reporting that files didn't exist when they definitely existed. She traced the problem down into the system library. Let's see if you can spot what's wrong: { Delphi / Kylix Cross-Platform Runtime Library } { System Utilities Unit } { } { Copyright (c) 1995-2001 Borland Softwrare Corporation } ... function FileAge(const FileName: string): Integer; {$IFDEF MSWINDOWS} var Handle: THandle; FindData: TWin32FindData; LocalFileTime: TFileTime; begin Handle := FindFirstFile(PChar(FileName), FindData); if Handle <> INVALID_HANDLE_VALUE then begin Windows.FindClose(Handle); if (FindData.dwFileAttributes and FILE_ATTRIBUTE_DIRECTORY) = 0 then begin FileTimeToLocalFileTime(FindData.ftLastWriteTime, LocalFileTime); if FileTimeToDosDateTime(LocalFileTime, LongRec(Result).Hi, LongRec(Result).Lo) then Exit; end; end; Result := -1; end; {$ENDIF} function FileExists(const FileName: string): Boolean; {$IFDEF MSWINDOWS} begin Result := FileAge(FileName) <> -1; end; {$ENDIF} The first function here is FileAge, which returns the last modified timestamp on a file. Note the use of FileTimeToDosDateTime, which is a Windows API function. It converts LocalFileTime and stores the date part in the first output parameter (LongRec(Result).Hi) and the time part in the second output parameter (LongRec(Result).Lo). Result, in this case, is our return value. If anything goes wrong, we return -1. The FileExists function then, simply calls FileAge. If it doesn't return a -1, there must be a file there. That's an awkward, weird solution to the problem. There has to be a system call that can answer that question more obviously. But it doesn't seem like it should be blowing up- it looks like it should work. But note that FileTimeToDosDateTime also returns a boolean value. If it succeeds, great, but if it fails, it returns false ## The Thumb That Ran Ahead of the Finger: Anatomy of a Compose Slider Bug DevFeed: [The Thumb That Ran Ahead of the Finger: Anatomy of a Compose Slider Bug]() Original publisher: [Read original article]() Author: Vitaliy Gribko Published: 2026-09-14T04:19:34Z Content type: article Language: en Sources: [ProAndroidDev - Medium]() Topics: [bug](), [Compose](), [Android](), [Design system](), [Code]() Tags: [android](), [bug](), [code](), [compose](), [debugging](), [design-system](), [jetpack-compose](), [kotlin](), [qa](), [race-condition](), [ui]() ### AI overview This article examines a deterministic bug in a custom Compose slider where the thumb moves ahead of the user's finger during a drag. It traces the issue to a design-system slider forked from the AOSP Material implementation and discusses debugging and code simplification. ### Source excerpt A bug report sat in the backlog for seven months. The fix took a day, deleted a third of the slider's logic, and was almost shipped with a second bug inside -- until a machine read my diff better than I did. This is the whole story: the ported behavior that never made sense, the race nobody reported, and why the best fixes remove code. The report The bug report was seven months old when it reached me. A QA engineer had filed it in December, with a screen recording and three steps: Open the people search filters. Grab the right-hand thumb of the age range slider. Drag it slowly to the left. The recording showed the problem in two seconds. The thumb does not follow the finger. It sprints ahead -- you are still crossing the gap between two ticks, and the thumb is already standing on the next one, waiting for you, like a dog that runs to the park while you are still tying your shoes. Expected: the thumb moves with the finger. Actual: it escapes. On a budget phone, on two Android versions, every time. Not a race condition, not a flake -- a perfectly deterministic lie, filmed in December, assigned to a fix-day in July. Seven months is not negligence. It is the natural half-life of a visual glitch filed as minor against a screen nobody dies on. The age filter works. You tap a tick, the value applies. Only the drag -- the one gesture the slider exists for -- feels wrong in a way that is hard to screenshot and easy to deprioritize. When the ticket finally landed on my desk, a colleague glanced at it and asked whether it had already been fixed once. It had not. But I understood his confusion later, when I opened the slider's source and found a comment that explained everything -- including why this bug felt so old. The comment that confessed The slider is not the framework's slider. Our design system ships its own Compose slider, forked from the AOSP Material one, because design needed three knobs the framework does not expose: a custom thumb radius, a custom track height, a differ ## A tag input that feels like a real product DevFeed: [A tag input that feels like a real product]() Original publisher: [Read original article]() Author: Marko Published: 2026-09-12T09:00:23Z Content type: tutorial Language: en Sources: [Marko Denic Tech]() Topics: [GUI](), [bug](), [Accessibility]() Tags: [blog-for-developers](), [bug](), [build-faster](), [code-productivity](), [code-smarter](), [content-monetization](), [css](), [css-animation](), [css-performance](), [developer-growth](), [developer-resources](), [email-newsletter-for-coders](), [forms](), [front-end-development](), [github-profile-automation](), [html](), [html-tips](), [javascript](), [javascript-tricks](), [learn-to-code](), [product](), [responsive-design-tips](), [ui](), [ux](), [web-dev-newsletter](), [web-development](), [web-development-tips](), [weekly-dev-tips](), [workflow-optimization]() ### AI overview A tutorial on building a robust tag-input control.
