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

.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] 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

SQL code smells
Posted by jpluimers on 2019/10/31
A while back I bumped into [WayBack] SQL Code Smells – Simple Talk, which is an extensive article covering all sorts of SQL related code smells.
It reminds me that one day I need to dig up some old links on other code smells as well.

Public database servers
Posted by jpluimers on 2019/10/30
I could not find any vendors/architectures have public database servers.
So there is no good way to go beyond SQLFiddle (of which I wrote before in SQL Fiddle | A tool for easy online testing and sharing of database problems and their solutions and David Rodriguez: a few nice posts on SQL (via: Google+)), that does not provide database access, but allows you to fire SQL statements onto these architectures:
- MySQL 5.6
- Oracle 11g R2
- PostgreSQL 9.6
- PostgreSQL 9.3
- SQLite (WebSQL)
- SQLite (SQL.js)
- MS SQL Server 2017
I get the thing (it is very hard to secure an “over the internet” connection to a database server; do NOT do this: [WayBack] connectivity – Connect to SQL Server over Internet – Database Administrators Stack Exchange), so the alternative is to run locally.
If you run locally, there are plenty of example/demo database, like:
- [WayBack] MySQL :: Employees Sample Database
- [WayBack] SQLite Sample Database And Its Diagram (in PDF format)
- for SQL server
- [WayBack] How to Download the Stack Overflow Database via BitTorrent – Brent Ozar Unlimited® via [WayBack] Where are the Stack Exchange data dumps? – Meta Stack Exchange
- The good old [WayBack] Release AdventureWorks sample databases · Microsoft/sql-server-samples · GitHub via [WayBack] Microsoft SQL Server Product Samples: Database – CodePlex Archive
- Note that in the release, the first link to [WayBack] AdventureWorks-oltp-install-script.zip is correct, but the second one gives you a 404.
- I find it easiest is to install from script; see [WayBack] sql-server-samples/README.md at master · Microsoft/sql-server-samples · GitHub: Install from a script
- download AdventureWorks-oltp-install-script.zip and extract the zip file to the C:\Samples\AdventureWorks folder.
- Open
C:\Samples\AdventureWorks\instawdb.sqlin SQL Server Management Studio and follow the instructions at the top of the file.
In step 2, do not forget to set the query window to
SQLCMDsyntax. Or just run the script using the [WayBack] sqlcmd Utility | Microsoft Docs (which reminds me I should update SQL Sever: batch files to find instances and sqlcmd.exe/osql.exe)
