From 2023: It’s Time For A Change: datetime.utcnow() Is Now Deprecated – miguelgrinberg.com

Posted by jpluimers on 2025/10/14

I forgot how I bumped into this, but a while ago I found this interesting 2023 post: [Wayback/Archive] It’s Time For A Change: datetime.utcnow() Is Now Deprecated – miguelgrinberg.com explaining naive (without time zone) and aware (with time zone) date time objects.

It reminded me of Delphi, where NowUTC – as Delphi does have neither naive or aware date time objects – returns  a floating point value (yes, it has a separate TDateTime type, but it represents the number of days that have passed since December 30, 1899 which in face stems from the Windows OLE Automation era* (OLE Automation is a subset of COM), see [Wayback/Archive] DateTime.ToOADate Method (System) | Microsoft Learn.

That method is mentioned in [Wayback/Archive] Why You Should Use NowUTC Instead of Now in Delphi: A Quick Guide – YouTube and Delphi deserves a way better infrastructure of date and time handling.

So this post is also a reminder to myself: figure out if there is an object oriented DateTime library for Delphi yet, and if not see if there is interest to create one similar to [Wayback/Archive] Noda Time | Date and time API for .NET by Jon Skeet.

Algorism and algorithm are named after Muhammad ibn Musa al-Khwarizmi, founder of algebra (via @annefleurdd)

Posted by jpluimers on 2025/10/14

I was in my 50s when I learned that both algorism and algorithm are named after the 9th-century Persian mathematician Muhammad ibn Musa al-Khwarizmi who founded algebra.

finding duplicates – voidtools forum

Posted by jpluimers on 2025/10/07

That feeling you have been living under a stone since 2014: [Wayback/Archive] finding duplicates – voidtools forum

1.4 Beta has both dupe: & sizedupe: functions.
(In the Index, you need to index the file size & also enable Fast size sort.)

You can combine them, something like:

> dupe: sizedupe: c: file:

Or even add a size to it:

> dupe: sizedupe: c: file: size:>2MB

Note that that finds file name AND (I believe its an AND) file size duplications – anywhere, not necessarily limited to C:, & also that name AND size are the only qualifications for “duplication”, as in files meeting that criteria may not be (byte-by-byte) “duplicates”.

A partial excuse is that these never made it to the changelog at [Wayback/Archive] www.voidtools.com/Changes.txt or [Wayback/Archive] www.voidtools.com/BetaChanges.txt.

It is in the documentation since May 2017 at [Wayback/Archive] Searching – voidtools though:

Liquidated: ISOSTEEL Deutschland GmbH, Wiesbaden

Posted by jpluimers on 2025/10/02

Just found out about the liquidation of [Wayback/Archive] ISOSTEEL Deutschland GmbH, Wiesbaden.

Their availability of spare caps were the reason for getting their thermos flasks and caps in the first place. As a bonus, their flashs had a wide opening as well. Much wider than the 25+ year old HEMA thermos flasks I used before (one of which the cap had died, the other one lost its vacuum):

The Isosteel caps are slowly dying, which means I need to find an alternative brand that provides spare parts and has a large flask opening, and kept liquid hot for 24 hours or cold for 48 hours. Just see their prior products at [Wayback/Archive] “ISOSTEEL – Isoliergefäße aus Edelstahl”.

Liquidation:

Question got closed in May 2025 due to bureaucrazy: Sites for beginning Delphi programmers – Stack Overflow

Posted by jpluimers on 2025/10/01

The whole idea of “community questions” was to create collective topics or references about important material without gaining any “points”.

Stack Exchange has left that concept in the dark by closing questions like this 2010 one that still contains relevant links: [Wayback/Archive] Sites for beginning Delphi programmers – Stack Overflow

The next step by their moderators is to delete the question, which will lose the valuable material forever.

Stack Exchange also dislikes humour.

And Embarcadero keeps deleting useful sites.

So for posterity, here is the question plus answers in full, amended with archived versions of each link when still available (I used † to mark the dead ones):
