Drawing with nice handwriting
Posted by jpluimers on 2021/11/10
Did you also wonder about the nice handwriting in the diagrams of yesterday’s post @adamsand0r drew up a few sketches of design decisions needed to be taken when building a #gitops-based CD pipeline « The Wiert Corner – irregular stream of stuff?
I did too.
They are from [Archive.is] Excalidraw | Hand-drawn look & feel • Collaborative • Secure, with source code at [Archive.is] GitHub – excalidraw/excalidraw: Virtual whiteboard for sketching hand-drawn like diagrams.

🔎Julia Evans🔍 on Twitter: “ten questions about UDP”
Posted by jpluimers on 2021/11/10
From a while back, but still relevant when you learn all your life:
[Archive.is] 🔎Julia Evans🔍 on Twitter: “ten questions about UDP: “
Hello! Here are some questions & answers. The goal isn’t to get all the questions “right”. Instead, the goal is to learn something! If you find a topic you’re interested in learning more about, I’d encourage you to look it up and learn more

OpenSuSE tumbleweed switched to using /etc/sudoers.d which broke yast module sudo somewhere mid 2020
Posted by jpluimers on 2021/11/09
Mid 2020, I re-installed a Raspberry Pi 2 box based on OpenSuSE Tumbleweed.
To my susprise the yast2 module sudo could not write the configuration.
It appeared that /etc/sudoers had become readonly and a new /etc/sudoers.d was created.
You can use visudo to edit files in that directory without potentially losing changes in /etc/sudoers during upgrades. I think that is a good move.
To bad the yast module failed because of it.
More on visudo and the /etc/sudoers.d directory:
- [Wayback] Visudo Manual
- [Wayback] ubuntu – Why does the system have /etc/sudoers.d? How should I edit it? – Super User
- [Wayback] permissions – adding local content in /etc/sudoers.d/ instead of directly modifying sodoers file via visudo – Ask Ubuntu

/me is a 1x.engineer
Posted by jpluimers on 2021/11/09
It is totally OK to be an 1x engineer instead of a 10x engineer.
The link below shows why, what 1x engineers actually do and how much value they add.
[WayBack/Archive.is] 1x Engineer
The official website of 1x Engineers around the world.
If you have more to add to that list, feel free to add a pull request to the underlying repository: [WayBack/Archive.is] GitHub – cutenode/1x.engineer: The official website of 1x Engineers around the world

Some links on Delphi compiler potential speed improvements…
Posted by jpluimers on 2021/11/04
A long time ago, there was an interesting blog post referenced from [WayBack] See how you can use Delphi’s upcoming new language feature to improve performance of your code. – Erik van Bilsen – Google+ referred to [WayBack] Inline Variables can increase performance – grijjy blog which made me comment [WayBack] “given the potential performance improvements the compiler already could do, and how long they could have been done, I would not bet on these new improvements becoming reality anytime soon.” that I later backed up with these links:
- [WayBack] Which Delphi compiler produces faster code? – Synopse
- [WayBack] Floating Point Optimization Comparison in Delphi 2007 and XE3 | Technology of Computing
- [WayBack] Following on from the recent discussion (…) on C# performance (compared to Delphi), I upda… – David Heffernan – Google+
- [WayBack] optimization – Does Delphi XE produce faster code than Delphi 2007? – Stack Overflow
One of the observations there is that since Delphi 2005, no major compiler speed improvements have been done, and that even between Delphi 5 and 2005 mot much has been done either.
From my point of view, the – not so big – Delphi compiler team is very busy keeping balls up in the air supporting the many compiler targets and architecture changes that have been introduced over the past decade or so, that they do not have resources to improve code generation other than rely on the LLVM tool chain (which is not used for Windows x86 and x64 development that covers like 90+% of the Delphi users).
In my book, when you need an “inline var”, you usually want to refactor that bit of code into a separate method anyway.
Refactoring out parts of code that have implicit try/finally blocks for managed variables or records is a strategy that can improve execution speed in many Delphi applications anyway, especially if that piece of code is outside of the happy flow: it moves unneeded overhead out of that flow.
This is actually a strategy used for instance in the Spring4D library: Stefan Glienke has a very good insight in how the compiler works and did magic to some performance critical code paths there.

Windows 10: remove applications from the uninstall list
Posted by jpluimers on 2021/11/04
After doing Windows upgrades to Windows 10, every now and then I bump into applications that do not fully uninstall themselves and get stuck on the uninstall list (that you get when running appwiz.cpl or browse to the Control Pannel installed programs list).
[WayBack] How to Manually Remove Programs from the Add/Remove Programs List mentions to inspect registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall, but that didn’t include some of the applications.
Then I found [WayBack] Remove entry from Windows 10 Apps & Features – Super User, where the answers mentions two other keys (thanks users [WayBack] Kreiggott and [WayBack] NutCracker):
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\UninstallHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
Neat!
So I made the below PowerShell script to dump installed programs.
It grabs the list of registry keys containing installed software and their registry values, then empirically filters out most values that are also now shown in AppWiz.cpl.
Like database work, the values can have properties having a value or being null. So it’s SQL like expression galore to do the filtering.
This post is slightly related to Still unsolved since 2015 NetBeans: Bug 251538 – Your Installer is Creating Invalid Data for the NoModify DWORD Key which crashes enumeration of the Uninstall Key in at least PowerShell, where I already did (without documenting) some Uninstall spelunking.
## The collection of registry keys gives Name and Property of each registry key; where Property is compound containing all registry values of that key. ## Get-ItemProperty will get you all the values on which you can filter, including a few special PS* values that allow you to browse back to the registry key. # x86 installs on x64 hardware: http://stackoverflow.com/questions/12199372/get-itemproperty-not-returning-all-properties/12200100#12200100 $nonUninstallableSoftwareRegistryKeys = (@ (Get-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*)) + (Get-Item HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*) + (Get-Item HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*) #$nonUninstallableSoftwareRegistryKeys.GetType().FullName #$nonUninstallableSoftwareRegistryKeys | Get-Member #$nonUninstallableSoftwareRegistryKeys | Out-GridView #$nonUninstallableSoftwareRegistryKeys | Get-ItemProperty | Get-Member #$nonUninstallableSoftwareRegistryKeys | Get-ItemProperty | Out-GridView #Return $nonUninstallableSoftwareRegistryNameValues = $nonUninstallableSoftwareRegistryKeys | Get-ItemProperty | Where-Object { $_.SystemComponent -ne 1 -and $_.NoRemove -ne 1 -and $_.UninstallString -ne "" -and $_.UninstallString -ne $null } # Filters out most things that AppWiz.cpl will leave out as well. # Might need more fine tuning, but is good enough for now. # PSPath shows the path to the underlying registry key of each value $nonUninstallableSoftwareRegistryNameValues | Select-Object SystemComponent, NoRemove, DisplayName, DisplayVersion, UninstallString, PSChildName <#, PSPath #> | Sort-Object DisplayName | Out-GridView # Need to find a good way to output this in a really wide Format-Table text format.

I love the way it shows “Duden Offline”
Posted by jpluimers on 2021/11/04
This does not happen often, and I found the way that [WayBack] Duden Offline is indicated hilarious!
It’s just a “basic” HTML page showing the meaning of “Wartung” (German word for Maintenance).
Duden is het German equivalent of the Oxford English Dictionary.
Not all of the huge site was gone. Part of the “Rechtschreibung” was still there, including the Wikipedia entry (:
I wonder what that one shows during maintenance (:
Links:
- Gist with HTML source of the offline page
The HTML page is interesting because just a minority of it is HTML. The rest is a truckload of CSS and embedded fonts. It is interesting to see how it was built, as the CSS and HTML is very well structured.
- Duden – Wikipedia (by now, the 28th edition might be out in print)
- Oxford English Dictionary – Wikipedia (the 3rd edition that is in the works likely might never be ever printed)
