On my reading list: Windows Console and PTY

Posted by jpluimers on 2022/10/25

With the rise of *nix tools and infrastructure on Windows (including, but certainly not limited to Visual Studio Code and Windows Subsystem for Linux), I need to get acquainted to the new ways these interface to the Windows Console.

Since Windows Console is from the (now obsolete) UCS-2 days, so it is not even fully Unicode aware, and has trouble with UTF-8, UTF-16.

So here are some links for my reading list:

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:

I had some Windows ATOM issues before, but this beats them easily

Posted by jpluimers on 2022/10/19

I’ve had some issues with Windows ATOM tables filling up, but nothing like this security bypass:

A new Windows code injection technique, atombombing, which bypasses current security solutions.

Note that since writing the first draft, the above AtomBombing article moved via Wayback: blog.ensilo.com to [Wayback/Archive.is] AtomBombing – A Brand New Code Injection Technique for Windows | FortiGuard Labs.

LPRng: RESOURCES – PostScript, Epson, HP, Xerox, PPD, etc

Posted by jpluimers on 2022/09/28

When writing Some links on PostScript books and online content, back from the days, I archived [Wayback] Index of /RESOURCES from the site hosting the [Wayback/Archive.is] LPRng Web Page (see also LPRng on Wikipedia):

The LPRng software is an enhanced, extended, and portable implementation of the Berkeley LPR print spooler functionality. While providing the same interface and meeting RFC1179 requirements, the implementation is completely new and provides support for the following features: lightweight (no databases needed) lpr, lpc, and lprm programs; dynamic redirection of print queues; automatic job holding; highly verbose diagnostics; multiple printers serving a single queue; client programs do not need to run SUID root; greatly enhanced security checks; and a greatly improved permission and authorization mechanism.

The source software compiles and runs on a wide variety of UNIX systems, and is compatible with other print spoolers and network printers that use the LPR interface and meet RFC1179 requirements.

Subdirectories (the PPD one goes one level deeper with both files and directories; XEROX just has a subdirectory with one file):

Python Breaking Distance calculator (includes the German DIN 1451 font for traffic signage)

Posted by jpluimers on 2022/09/20

If you ever want a good visual representation to compare the breaking distance for a car at two different speeds, and see at what speed you will hit the human “obstacle”, then use the Python script mkbremsweg.py.

Git repository: [Wayback/Archive.is] joschtl / bremsweg · GitLab.

The image is generated in the current directory

It probably won’t work on Windows as it dynamically builds a very long command-line calling ImageMagick tool [Wayback/Archive.is] convert once to do all the drawing.

The text in the picture for now is hardcoded in German, but would be easy to adopt.

The fonts used are and FreeSans and [Wayback/Archive.is] Alte DIN 1451 Mittelschrift Font Family · 1001 Fonts (which the Germans use for Traffic Signage and is very similar to fonts used in other countries).

Calculations are based on [Wayback/Archive.is] Bremsweg-Rechner für Anhalteweg & Bremsweg – Johannes Strommer.

Since about 5 months now, there has been a new Chocolatey package maintainer for OpenVPN

Posted by jpluimers on 2022/08/26

Last winter, I discovered that the OpenVPN version on Chocolatey was really old: it had not been updated since 2019.

Most  Chocolatey maintainers are volunteers and sometimes the burden can become too large. Back then the maintainer was [Wayback/Archive] Chocolatey Software | wget, but luckily [Wayback/Archive] Chocolatey Software | dgalbraith has stepped in and in March 2022 bumped the version from [Wayback/Archive] Chocolatey Software | OpenVPN 2.4.7 to [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.4 and kept maintaining (currently there is [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.7).

Legacy Windows: Why are console windows limited to Lucida Console and raster fonts? – The Old New Thing

Posted by jpluimers on 2022/08/15

I think this holds to or maybe even including Windows Vista: [Wayback] Why are console windows limited to Lucida Console and raster fonts? – The Old New Thing

The workaround is in KB247815.

Luckily, many old KB articles are still in the BetaArchive (see the blog post Source: Missing a KB article? Try the Microsoft KB Archive – BetaArchive Wiki last month), including [Wayback/Archive.is] Microsoft KB Archive/247815 – BetaArchive Wiki

Windows NT 4 / Windows 2000: Necessary criteria for fonts to be available in a command window

…

An unsupported work around is available by adding the following font specific entry:

Add a String Value
Name=00
Data= “Font Name” (without “”)

Into the following registry:

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Console\TrueTypeFont

The name needs to be incrimented with “0” for each additional font. The Data entry needs to match the font’s entry in the following registry location:

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Fonts

Some notes on Input Director and alternatives: what about multiple platforms and mixing local plus remote access?

Posted by jpluimers on 2022/07/29

More than 10 years ago, I wrote about 7 screens; 3 computers; 1 keyboard/mouse to direct them all: Input Director and started with

At home, I have 7 screens on 3 computers on the same desk. That sounds like a clutter, but all these keyboards and mice hooked up to them add even more clutter. Until I found out about Input Direct…

In the mean time, I’ve mainly used a Mac with MacOS as a front-end to virtually logon to remote machines using both the internal display and one or two external monitors.

Especially when doing video (think Covid-19 and especially on-line meetings!) in addition to software development work, this is far from ideal.

So here are some things on my list of potential enhancements to this situation:
