Reminder to self: check to see the state of winget and if it is possible to install Windows Store applications from the command-line

Posted by jpluimers on 2022/11/02

While undergoing many treatments against rectum cancer, I saved the below tweets with a marker “The new windows package manager: aka.ms/winget“.

[Wayback/Archive] aka.ms/winget

Well, actually the first tweet is gone, now, but archived as [Wayback/Archive] Stefan Stranger on Twitter: “New Windows Package Manager #MSBuild2020… “

PowerShell: working around Get-NetFirewallRule not showing all the fields that Set-NetFirewallRule allows you to set

Posted by jpluimers on 2022/10/26

With APIs, you always hope that Get and Set methods mirror each other. More often than not, they don’t.

Take for instance these two:

They are far from symmetric: [Wayback/Archive] Get-NetFirewallRule shows far less than [Wayback/Archive] Set-NetFirewallRule allows you to set (first and foremost the various port related properties). It can be worked around though.

There are a few posts discussing this, of which I think these two are the most important:

Both above posts via [Wayback/Archive] “Get-NetFirewallRule” “LocalPort” – Google Search.

This is what I was after:

PowerShell "Get-NetFirewallRule -Name 'RemoteDesktop-UserMode-In-TCP' | Select-Object Name,DisplayName,Enabled,Direction,@{Name='Protocol';Expression={($PSItem | Get-NetFirewallPortFilter).Protocol}},Action,@{Name='LocalPort';Expression={($PSItem | Get-NetFirewallPortFilter).LocalPort}}"

Or actually:

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.

GoogleDriveFS - cannot find libcef.dll

Don’t you love errors after things try to audo-update themselves without testing preerquisites:

---------------------------
GoogleDriveFS.exe - System Error

The program can't start because libcef.dll is missing from your computer. Try reinstalling the program to fix this problem.

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).
