A load on agility related posts referenced by Markus Eggers – Google+

Posted by jpluimers on 2020/08/13

A while ago, Markus Eggers – Google+ started following me on G+, so I found out about his posts: most of them refer to very useful agility related ones.

So my reading list just got a bit longer, with tuples on Markus Eggers – Google+ and where it points to.

I give that a double “no”, they are not requirements and that is not anything we really need. User stories are about being able to explore options and seize opportunities. Requirements are about deciding up front and sticking with that.

PlantUML – Visual Studio Marketplace

Posted by jpluimers on 2020/08/12

This and built-in markdown support made the switch to Visual Studio code from Atom.io so much easier: [WayBack] PlantUML – Visual Studio Marketplace.

Atom.io was already on my list of tools to say good bye to: though a good project to show the versatility of the Electron Framework, over time – like Google Chrome – it had become a memory and CPU hog and a drag to use and update.

Integrating debuggers and other parts of the development life cycle involved too much fuzz, for which Visual Studio code (also known as vscode) was much easier from the start.

Probably Visual Studio code did not suffer from what the Dutch call Law of the handicap of a head start: it is much more responsive and versatile than Atom.io. Also the plugins – despite having come to the market later – feel way more mature in Visual Studio code than Atom.io.

Finally, the PlantUML support extension for vscode is so much nicer than in Atom.io, it for instance supports live updating and in addition to local rendering, rendering through a PlantUML server (see [WayBack] GitHub – plantuml/plantuml-server: PlantUML Online Server).

Source code is at [WayBack] GitHub – qjebbs/vscode-plantuml: Rich PlantUML support for Visual Studio Code.

Comparing versions with wildcards and without them (for instance for semantic versioning)

Posted by jpluimers on 2020/08/12

For a project I’m going to be in need to compare version numbers.

I’m not sure yet if I need wildcards, or can leave them out (but for partial semantic versioning, I might need them).

Below a bunch of links that should get me started.

From a quick glance: versioning is hard, comparing even harder.

On versioning in general

Numeric versioning (usually without wildcards):

On semantic versioning (SemVer for short):

[WayBack] Semantic Versioning 2.0.0 | Semantic Versioning
- [WayBack] GitHub – scottcorgan/compare-semver: Compare semver versions to many other semver versions
- [WayBack] Simple Versioning · GitHub: A simple, pragmatic versioning convention.In a sense, this is a subset of SemVer, but with slightly different semantics.
- [WayBack] Why Semantic Versioning Isn’t · GitHub – an essay – followed by a lively discussion – against SemVer which turns out to actually end in favour of SemVer
[WayBack] Just published my smallest ever open source project – 1 unit (not counting the unit tests) … – Vincent Parrett – Google+
- [WayBack] GitHub – VSoftTechnologies/SemanticVersion: Semantic Version Parser for Delphi
- Nice discussion on in versus CharInSet versus IsDigit versus IsInArray
[WayBack] Semantic Version C# class · GitHub
[WayBack] c# – Is there a NuGet package that contains a semantic version parser in .NET? – Stack Overflow
[WayBack] Semantic Version Functions | sprig Useful template functions for Go templates.
[WayBack] GitHub – zafarkhaja/jsemver: Java implementation of the SemVer Specification
[WayBack] Semantic version utility · Issue #566 · stedolan/jq · GitHub
[WayBack] semver: Basics
[WayBack] GitHub – substack/semver-compare: compare two semver version strings, returning -1, 0, or 1

On the C# Version class (which handles most of semantic versioning except: leading zero’s, very large numbers, non-numeric release specifiers)

[WayBack] validation – C# Compare two versions using wildcard – Stack Overflow
[WayBack] c# – Compare version numbers without using split function – Stack Overflow

[WayBack] Version.CompareTo Method (Object) (System) which does not regard undefined (-1) as wildcards by documenting

    // A Version object contains four hierarchical numeric components: major, minor,
    // build and revision.  Build and revision may be unspecified, which is represented 
    // internally as a -1.  By definition, an unspecified component matches anything 
    // (both unspecified and specified), and an unspecified component is "less than" any
    // specified component.

[Archive.is] referencesource.microsoft.com/#mscorlib/system/version.cs

[WayBack] Version Class (System) The value of Version properties that have not been explicitly assigned a value is undefined (-1); Ordinarily, the Version class is not used to assign a version number to an assembly. Instead, the AssemblyVersionAttribute class is used to define an assembly’s version, as illustrated by the example in this topic.

Interesting idea, but not sustainable: using floating point values to compare versions:

[WayBack] Comparing program versions (in C# and Python)
- [WayBack] ProgramVersion.cs · GitHub
- [WayBack] program_version.py · GitHub

On wildcards:

2008 [Archive.is] Matching Wildcards: An Algorithm | Dr Dobb’s: A simple wildcard text-matching algorithm in a single while loop
2014 [ Archive.is] Matching Wildcards: An Empirical Way to Tame an Algorithm | Dr Dobb’s: Optimizing and testing a wildcard algorithm to get 5x performance improvement.

Installing and updating Windows PowerShell – via Microsoft Docs

Posted by jpluimers on 2020/08/11

Since I keep forgetting that PowerShell is part of WMF (Windows Management Framework) and about the compatibility/installation matrix: [WayBack] Installing Windows PowerShell | Microsoft Docs:

The installation package for PowerShell comes inside a WMF installer. The version of the WMF installer matches the version of PowerShell; there’s no stand alone installer for Windows PowerShell.

If you need to update your existing version of PowerShell, in Windows, use the following table to locate the installer for the version of PowerShell you want to update to.

Windows PS 3.0 PS 4.0 PS 5.0 PS 5.1

Windows 10 (see Note1)
Windows Server 2016 – – – installed

Windows 8.1
Windows Server 2012 R2 – installed [WayBack] WMF 5.0 [WayBack] WMF 5.1

Windows 8
Windows Server 2012 installed [WayBack] WMF 4.0 [WayBack] WMF 5.0 [WayBack] WMF 5.1

Windows 7 SP1
Windows Server 2008 R2 SP1 [WayBack] WMF 3.0 [WayBack] WMF 4.0 [WayBack] WMF 5.0 [WayBack] WMF 5.1

Windows	PS 3.0	PS 4.0	PS 5.0	PS 5.1
Windows 10 (see Note1) Windows Server 2016	–	–	–	installed
Windows 8.1 Windows Server 2012 R2	–	installed	[WayBack] WMF 5.0	[WayBack] WMF 5.1
Windows 8 Windows Server 2012	installed	[WayBack] WMF 4.0	[WayBack] WMF 5.0	[WayBack] WMF 5.1
Windows 7 SP1 Windows Server 2008 R2 SP1	[WayBack] WMF 3.0	[WayBack] WMF 4.0	[WayBack] WMF 5.0	[WayBack] WMF 5.1

For historic reference:

Windows 6.1 (Windows 7 and Server 2008 R2) come with PowerShell 2.0.
Windows 6.0 (Windows Vista and Server 2008) came with PowerShell 1.0.

VMware ESXi 6.5: “Failed – An error occurred during host configuration.” when starting the NTP service

Posted by jpluimers on 2020/08/10

I tried repeating VMware KB: Configuring Network Time Protocol (NTP) on ESX/ESXi hosts using the vSphere Client in ESXi 6.5 using the web-client (the steps are very similar, see [WayBack] How to configure ESXi 6.5 Network Time Protocol (NTP) via Host Client? | ESX Virtualization).

It failed with the non-descriptive “Failed – An error occurred during host configuration.”:

Viewing the details isn’t of much help as you do not get extra information:
