This is a cool library which I missed when it was introduced while recovering from my extensive cancer treatments:

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:
