The Channel9 programming languages guys to watch: Eric and Erik
Posted by jpluimers on 2019/11/05
When watching the episodes of Eric and Erik,
They both worked on the C# team, but have lots of experience designing and developing other languages.
Their views of the languages, teams and companies that make software today is enlightening as basically more and more companies should be software companies but forgot they are.
I’ve been advocating this to both large and small companies since the mid 1990s and by now you see the people getting it are having a blast.
When you look at the language leve, you clearly see how slowly progress is made and how far most languages are behind. I think both the JVM, CLR, LLVM and JavaScript are the foundations to base on but that tooling is still very much in its infancy.

When whas the global FormatSettings variable deprecated?
Posted by jpluimers on 2019/11/05
Reminder to self to check out when [Archive.is] FormatSettings global variable of type [WayBack] TFormatSettings was deprecated as it was only documented as of Delphi 2010 but available much much earlier.

Meeting Ticker – the real cost of a meeting visualised
Posted by jpluimers on 2019/11/04
Ever figured out how costly meetings are?
Show the [WayBack] Meeting Ticker during a meeting and be amazed after filling in just a few fields:
Of course it is open source: github/tobytripp/meeting-ticker
And I also found who originally referred me to it: [WayBack] Weekend Reader 2017.48 – reality-loop

.NET: IHostedService – hosting services inside any .NET process
Posted by jpluimers on 2019/10/31
Have any service related stuff implement IHostedService, so it is easy to deploy it in all kinds of processes:
- console to test
- windows service
- ASP.NET Core service
- Linux host application
Peter Groenewegen ([WayBack] pgroene (Peter Groenewegen) · GitHub; [WayBack] { Think Rethink }) has some great examples and blog articles at [WayBack] IHostedService – { Think Rethink }:

- [WayBack] Application Shutdown in ASP.NET Core with IApplicationLifetime – { Think Rethink }: Learn how to gracefully handle Application Shutdown in ASP.NET Core by looking at the handling of flushing the application insights messages when asp.net core exits
- [WayBack/Archive.is] Run scheduled background tasks in ASP.NET Core – { Think Rethink }: In the previous blog post called background tasks with ASP.NET Core using the IHostedService Peter described how to use the IHostedInterface for background tasks. In this post, we continue on this …

- [WayBack] Having Fun with the .NET Core Generic Host · Jonathan’s Blog
As ASP.NET developers we’re fairly used to hosting our code inside Internet Information Services (IIS). However, since ASP.NET Core is cross-platform, hosting inside IIS isn’t always an option. For that reason, the hosting model for ASP.NET Core applications looks quite a bit different. Of course, we can still host our code in IIS, but we also have the option to use Kestrel and run as a standalone application.This new hosting model is visible in code through the WebHostBuilder API from Microsoft.

Learn about Kestrel, the cross-platform web server for ASP.NET Core.
Kestrel is a cross-platform web server for ASP.NET Core. Kestrel is the web server that’s included by default in ASP.NET Core project templates.
Kestrel supports the following features:
- HTTPS
- Opaque upgrade used to enable WebSockets
- Unix sockets for high performance behind Nginx
Kestrel is supported on all platforms and versions that .NET Core supports.

Before using the PPL, I need to check to see if a few things have been fixed yet
Posted by jpluimers on 2019/10/31
Before using the PPL ever, I need to check out at least a few posts like these:
- [WayBack] I try use PPL and ITask, but I get strange things… – Jacek Laskowski – Google+ if you start existing ITask instances faster than TQueueWorkerThread.Execute can schedule them, they are all scheduled on the same thread [Archive.is] https://pastebin.com/aA6s9Q6Y
- [WayBack] … there’s a bug in Berlin/Tokyo which causes thread pool tasks to be executed serially instead of in parallel… – Primož Gabrijelčič – Google+: in some Delphi versions, TParallel.Join does not work and you need to do TTask.WaitForAll.
Most of the PPL code was written by Allen Bauer when he was Chief Scientist at Embarcadero in the 2007-2010 time frame and it was still called DPL (Delphi Parallel Library). The code was released in Delphi XE7 (see [Archive.is] Using the Parallel Programming Library – RAD Studio) but seems hardly maintained after he left.
You can find some of his notes at [Archive.is] The Oracle at Delphi: Parallel Programming

Dixin’s Blog – Use Fiddler with Node.js
Posted by jpluimers on 2019/10/30
[Archive.is] Dixin’s Blog – Use Fiddler with Node.js Fiddler is an useful HTTP proxy debugger on Windows. It would be nice if it can work with Node.js applications. To do this, just need to proxy Node.js requests through Fiddler… on port 8888.
There is a snippet for it at github/Dixin/CodeSnippets/…/fiddler.js (now moved to [WayBack] github.com/Dixin/Blog/…/Blog/Dixin.Nodejs/fiddler.js)
It complements a few posts I’ve written about Fiddler using port 8888 as a proxy before:
- NTLM and Kerberos Authentication for a WebRequest and a WebProxy
- How to fill proxy information in cntlm config file (via: Stack Overflow)
- Using Chrome on Windows with a different proxy server than the system one (which is used by Internet Explorer)
- .NET/C# small program that shows you your proxy settings, demonstrates LINQ to Registry, and String.Contains

Antipatterns in software development, architecture and management
Posted by jpluimers on 2019/10/30
If you develop software, be sure you recognise Antipatterns just as well as Patterns.
Luckily [WayBack] SourceMaking has a full sub-site covering software development, -architecture and management AntiPatterns: [WayBack] AntiPatterns.
Of course it isn’t complete, so be sure to read [WayBack] The Majestic Monolith – Signal v. Noise as well.
via: [WayBack] Martin Fowler on Twitter: “It’s an old anti-pattern, and sadly is still going strong: The Entity Service Antipattern.”

E2398 Class methods in record types must be static (Delphi) – RAD Studio
Posted by jpluimers on 2019/10/29
[WayBack] E2398 Class methods in record types must be static (Delphi) – RAD Studio present since at least Delphi 2007 ([WayBack] E2398: Class methods in record types must be static).
This is a Delphi compiler limitation for records, that is not present for classes.
Maybe one day when record inheritance kicks in, this will be resolved (as Stefan Glienke hinted in the below tread), because currently Self (which is present in non-static class methods on classes) then points to the current type. In static class methods, there is no Self, which is OK as that would point to the only available type anyway.
Via: [WayBack] why a class method of a record without the static keyword raise E2998 error ? AFAIK it can not be anything else then static ?! – Paul TOTH – Google+
Note that [WayBack] Error and Warning Messages (Delphi) – RAD Studio shows various other errors around the use of static:
- [WayBack] E2355 Class property accessor must be a class field or class static method (Delphi) – RAD Studio
- [WayBack] E2366 Global procedure or class static method expected (Delphi) – RAD Studio
- [WayBack] E2376 STATIC can only be used on non-virtual class methods (Delphi) – RAD Studio
- [WayBack] E2380 Instance or class static method expected (Delphi) – RAD Studio
All are marked “No further information is available for this error or warning.“, though they would at least deserve some examples.
