A year ago on Telegram: “Do I need to use GarbageCollectAtoms in Delphi? I used it in delphi 7, but I dont know what is benefit. 😐”

Posted by jpluimers on 2022/10/20

Last week I found out that I had some Windows ATOM issues before, but this beats them easily was still a draft in stead if in the blog queue.

I got reminded to it by someone asking on Telegram about

“Do I need to use GarbageCollectAtoms in Delphi? I used it in delphi 7, but I dont know what is benefit. 😐”.

The short answer is: yes, if your Delphi application does terminate in a way that the Controls unit cannot cleanly unload (and cannot free the Windows atoms) or leaks Windows atoms in a different way. I have been in that situation and that’s why I wrote the above blog post that got published in 2016.

The longer answer is likely no, both the Windows atom and registered Windows message table share a heap and that registered VCL Windows message leaking bug got fixed some 10 years ago in Delphi XE2, see:

Wow, the Windows 3.x winfile.exe File Manager still lives on!

Posted by jpluimers on 2022/04/01

By sheer luck, Jen Gentleman pointed out that winfile.exe still lives on:

The source is at [Wayback/Archive.is] microsoft/winfile: Original Windows File Manager (winfile) with enhancements, and it looks exactly like the Windows 3.x through Windows NT 4.0 days.

The Evolution of Windows Search | Windows Search Platform

Posted by jpluimers on 2022/01/03

Great post [WayBack] The Evolution of Windows Search | Windows Search Platform, covering some 3 decades of search:

1991 (Cairo with WinFS)
1996 (Windows NT 4.0)
2000 (Windows 2000)
2001 (Windows XP)
2007 (Windows Vista)
2009 (Windows 7)
2012 (Windows 8.x)
2015 (Windows 10)

It is part 1 of a series of 4 posts by [WayBack] Brendan Flynn, Author at Windows Search Platform:

The Evolution of Windows Search 👈 You Are here

Windows Search Configuration and Settings

What’s in my index?

How to make the most of search on Windows

When grabbing them, only the first two parts were available. Part two was about [WayBack] Configuration and Settings | Windows Search Platform with an in depth coverage of both the old style Control Panel applet as the new Windows 10 Settings page.

The Windows key has no Unicode equivalent, so use ⊞ like Wikipedia and many others do

Posted by jpluimers on 2021/08/23

lFor Mac keyboard keys, almost all (except the old solid and open Apple logo’s) have a Unicode code point, see for instance the modifier keys from the [WayBack] List of Mac/Apple keyboard symbols · GitHub (the “Alt” column has a solid Apple logo in the bottom right; on non-Mac systems it will look differently as it is in the Unicode private range: [WayBack] Unicode Character ” (U+F8FF): ‘<Private Use, Last>’):

Sym Key Alt

⌃ Control

⌥ Option

⇧ Shift

⌘ Command 

Sym	Key	Alt
⌃	Control
⌥	Option
⇧	Shift
⌘	Command	

These are the code points for the “Sym” column:

⌃ – [WayBack] Unicode Character ‘UP ARROWHEAD’ (U+2303) (less wide than the below three)
⌥ – [WayBack] Unicode Character ‘OPTION KEY’ (U+2325)
⇧ – [WayBack] Unicode Character ‘UPWARDS WHITE ARROW’ (U+21E7)
⌘ – [WayBack] Unicode Character ‘PLACE OF INTEREST SIGN’ (U+2318)

Keys on many platforms

17 years ago, C:\nul\nul crashed/BSOD Windows; now $MFT does for Windows < 10

History repeating itself: [Archive.is] 31607 – C:\nul\nul crashes/BSOD then, now it’s this:

All versions prior to Windows 10 and Windows Server 2016 seem vulnerable.

So add $MFT to this list:

The following device names have been known to render a system unstable: CON,
NUL, AUX, PRN, CLOCK$, COMx, LPT1, and CONFIG$.

Oh BTW: history repeated itself this year too. With NUL

In short, Steven Sheldon created a rust package named nul which broke the complete package manager on Windows:

[WayBack] I think the name of this project causes issues for windows users. · Issue #1 · SSheldon/nul
- When cargo updates its crates.io registry, it creates a file for each crate, no extension, just the name.The name nul is not a valid name in windows 10, so cargo fails to update the registry, and then aborts whatever it was doing (building, searching, ect.).I think this project should be re-published to crates.io under a new name, something like null-strings perhaps?

BTW: one of my gripes on learning new languages is that they come with a whole new idiom of their ecosystem: rust, cargo, crates, all sound like being a truck mechanic to me.
