If you are on .NET, migrate to .NET Core. If you start with .NET, start with .NET Core.
Based on:

- [WayBack] Nick Craver on Twitter: “No clue! Honestly. There are enough wins from us in a .NET Core migration (e.g. maintenance, open source/fixes, SDK projects, running in a container or appliance, etc.) that performance literally isn’t on my list.

We are porting Continua CI to .net core 2.1, I’ve been working on it for a few months now (along with other things of course), I had to contribute to a few open source projects to help get all our dependencies onto .net core, and for the most part it’s been pretty easy. I did have to change the windows service stuff, and since there is no WCF server stuff in .net core we have to find a replacement for that for server to agent communications (still exploring options, but probably going with halibut).What hasn’t (and still isn’t) easy is porting MVC4/5 stuff to asp.net core. So many little changes that drive me absolutely potty. I was getting so frustrated that I had to put it aside for a while and work on other things, just to get my sanity back!

Reading files that are locked by other references: c# – Notepad beats them all? – Stack Overflow
Posted by jpluimers on 2018/08/16
Cool feature borrowed from Notepad, which can read files locked by other references (for instance a process having the handle open): [WayBack] c# – Notepad beats them all? – Stack Overflow.
The example from the answer is in .NET, but can be used in a native environment as well (Notepad is a native application).
Notepad reads files by first mapping them into memory, rather than using the “usual” file reading mechanisms presumably used by the other editors you tried. This method allows reading of files even if they have an exclusive range-based locks.
You can achieve the same in C# with something along the lines of:
using (var f = new FileStream(processIdPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) using (var m = MemoryMappedFile.CreateFromFile(f, null, 0, MemoryMappedFileAccess.Read, null, HandleInheritability.None, true)) using (var s = m.CreateViewStream(0, 0, MemoryMappedFileAccess.Read)) using (var r = new StreamReader(s)) { var l = r.ReadToEnd(); Console.WriteLine(l); }

Why Skylake CPUs Are Sometimes 50% Slower – How Intel Has Broken Existing Code – Alois Kraus
Posted by jpluimers on 2018/08/09
[WayBack] Why Skylake CPUs Are Sometimes 50% Slower – How Intel Has Broken Existing Code – Alois Kraus reports that the PAUSE instruction on Intel Skylake architecture takes an order of magnitude longer than on previous architectures.
This impacts spinlock code in .NET 4.x and .NET Core 2, and likely impacts other spinlock code as well. The .NET core fix gets back-ported to .NET 4.x.
Since Delphi XE, the Delphi RTL code has borrowed ideas from .NET implementing this kind of code, so I filed [WayBack] QualityCentral: 144063 PAUSE instruction on Intel Skylake takes order of magnitude longer: important for SpinWait/SpinLock code (because Google can index it).
It is no coincidence that a Senior Scaleability Engineer at Booking.com mentioned it on his G+ stream ([WayBack] The “Pause” instruction changed timing dramatically in Skylake. Spinlock implementation based on pause will need adjustments. – Kristian Köhntopp – Google+) as changes like this can heavily impact server systems.

Pretty printing HTML is the same as formatting code: How do you format code in Visual Studio Code (VSCode) – Stack Overflow
Posted by jpluimers on 2018/07/18
I was looking for a HTML pretty printer (…) but in Visual Studio code, that is called code formatting, which supports many languages out of the box (including HTML) without requiring extensions like Atom.io (see below).
The shortcuts are at [WayBack] How do you format code in Visual Studio Code (VSCode) – Stack Overflow.
For Mac OS X/OS X/MacOS they are (the second one only appears when you have a code selection):

Shift–Option–F- selection:

Visual Studio – Add File As Link
Posted by jpluimers on 2018/07/04
Since I forget where they hid the [WayBack] Visual Studio – Add File As Link feature, two images from the linked post:
- The icon in the link is different from the normal file:
- Adding as a link is not a separate menu item, but a modification of the file open dialog overlaying the default
Addbutton with two more options:Add;Add as Link(noteShow Previous Versionsis a feature of non-Home version of Windows Vista and up).
Do not double click the file name, as that will add (AND COPY TO THE CURRENT PROJECT DIRECTORY !!!1!!!) that file to your current project.
A step by step instruction is at [WayBack] c# – Add File as a Link on Visual Studio – Debug vs Publish – Stack Overflow.

I wish the Delphi language supported multi-line strings
Posted by jpluimers on 2018/06/21
Very often, I see people ask for how to embed multi-line strings in a Delphi source file.
The short answer is: you can’t.
The long answer is: you can’t and if you want you have to hack your way around.
The answer should be: just like any of these languages that do support multiline strings:
- Python
- embed them with triple single quotes or triple double quotes: [WayBack] 3. An Informal Introduction to Python — Python 3.6.1 documentation – strings
- JavasScript
- as of ECMAScript 6, you can use backticks: [WayBack] Template literals – JavaScript | MDN
- Ruby
- Via the Here Documents syntax: [Archive.is] File: literals.rdoc [Ruby 2.2.0] – Here Documents
- C#
- By prepending the opening double quote of a string with @: [Archive.is] Code: Generating Multiline String Literals (Visual C#)
Many languages support this through a feature called HEREDOC.
Now in Delphi and other languages like Java are building ugly workarounds like for instance this one: [WayBack] RAD Studio Tip: Using resource scripts to organize project dependencies. – Chapman World.
