From [WayBack] …short presentation at the Norway Delphi Club[1] meetup, covering some fun and interesting uses of the “new” language features introduce since Delphi7… – Asbjørn Heid – Google+
Yesterday I did a short presentation at the Norway Delphi Club[1] meetup, covering some fun and interesting uses of the “new” language features introduced after Delphi 7.
The main purpose of the talk was to try to be inspirational, and give a sense of what kind of stuff you can do with the language these days. So it’s not very in-depth, but rather tries to showcase several interesting features and tricks.
Anyway, in case it might be useful to others I thought I’d publish the slides and code here as well.
The examples are a nice introduction for when you want to dig deeper in the language itself, for instance when you are digging deeper into Spring4d.
Slides 35 and 36 – though hard for me to grasp initially – show a very nice concept called [WayBack] Partial Application (thanks Stefan Glienke for pointing me at this) by binding a parameter value plus parameter position to an existing function returning the bound function so it becomes easier to tall.

This looks smart
gem update `gem list | cut -d ' ' -f 1`From: [WayBack] How to Update All Your Ruby Gems At Once | Life, the Universe, and Everything
Though on the bash prompt, it works fine on Mac OS X / OS X / macOS / …, it does not work nice as an alias.
You can get it to work with difficult escaping (or nesting).
But it is easier to escape this:
gem update $(gem list | cut -d ' ' -f 1)
Escaped, it comes down to:
alias "gem-update-all=gem update \$(gem list | cut -d ' ' -f 1)"

There are still sites limiting password lengt to low values like 20 or 15. Don’t!
The why at [WayBack] Implement Proper Password Strength Controls: Password Length has been in place since October 2012, since when cracking passwords has become way faster, so risk at length 20 back then is now a risk at something like length 40.
Password Length
Longer passwords provide a greater combination of characters and consequently make it more difficult for an attacker to guess.
- Minimum length of the passwords should be enforced by the application.
- Passwords shorter than 10 characters are considered to be weak (NIST SP800-132).
While minimum length enforcement may cause problems with memorizing passwords among some users, applications should encourage them to set passphrases (sentences or combination of words) that can be much longer than typical passwords and yet much easier to remember.
- Maximum password length should not be set too low, as it will prevent users from creating passphrases. Typical maximum length is 128 characters.
- Passphrases shorter than 20 characters are usually considered weak if they only consist of lower case Latin characters.

Since I needed to know how to formulate external hyperlinks on a Wiki page: [WayBack] Help:Links – MediaWiki.
Too many options, not even counting other sections on that page I did not quote, so I went for the first.
To create an external link, usually to a page at a different website, enclose the URL followed by space and the link text in single square brackets (see examples below). When you save or preview the page, you will see a link rendered slightly differently than an internal wikilink. It may be a different color and/or be followed by an arrow icon to show that it may lead to another site.
Description You type You get External link with specified link text MediaWiki Numbered external link This is what happens if you omit the link text. Multiple links of this type on the same page are numbered sequentially.
[1] Bare external link URLs beginning with “
http://” and “https://” are automatically linked, even when no brackets are used.https://mediawiki.org Avoiding auto-linked URLs https://mediawiki.org Protocol-relativeexternal link The link will be HTTP or HTTPS depending on the protocol of the page currently being viewed (which could be different for different users). This is only supported inside of square brackets
[ ]. Using “//en.wikipedia.org” by itself does not result in a link.Wikipedia External link to the current server https://{{SERVERNAME}}/pagenamehttps://www.mediawiki.org/pagename External link to other host passing the pagename https://google.com/search?q={{PAGENAMEE}}See also: URL encoded page names, PAGENAMEE encoding
https://google.com/search?q=Links Mailto link email me Mailto named with subject line and body info Custom URI Any URI you wish to add needs to be first declared through $wgUrlProtocols. (This example is not enabled on Mediawiki.org)
[skype:echo123 call me] External links with file-type icons See External link icons for currently supported icons and extensions. Note that this wiki is not set up to use such icons.

I forgot about the announcement that Signal had also become available on the Desktop, but it is via [WayBack] https://signal.org/download/:
$ curl -s https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add -
$ echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
$ sudo apt update && sudo apt install signal-desktop
I like the mix of echo and tee to update the [WayBack] /etc/apt/sources.list.d folder with the signal-xenial.list file.
These links will always give you the latest download filename:
The files you get there will be relative to the path https://updates.signal.org/desktop/ so will be similar to:
Signal-win-1.0.36.exe -> https://updates.signal.org/desktop/Signal-win-1.0.36.exeSignal-mac-1.0.36.zip -> https://updates.signal.org/desktop/Signal-mac-1.0.36.zipYou can get the sources at https://github.com/WhisperSystems/Signal-Desktop/releases

The post [WayBack] Why is my buttons not created in logical order? If I run this, my buttons area created ACB rather than ABC as I expected… – Johan Swart – Google+ reminded me the trouble of Delphi VCL and FMX have with alignment.
Basically you have to position your control away from your intended alignment position in order for it to work. So this fails:
procedure TForm1.FormCreate(Sender: TObject);
var
myToolBar: TToolBar;
myCornerButton: TCornerButton;
i: Integer;
begin
myToolBar := TToolbar.Create(Self);
myToolBar.Parent := Self;
for i := 0 to 2 do
begin
myCornerButton := TCornerButton.Create(tbarGrid);
myCornerButton.Parent := myToolBar;
myCornerButton.Align := TAlignLayout.Left;
myCornerButton.Text := Chr(65 + I);
end;
end;
Basically you have to set myCornerButton.Left to 1 before setting the Align property.
Similar for the Top property and TAlignLayout.Top value.
The same holds for VCL Align values alLeft with setting the Left property and alTop with setting the Top property before setting Align.
See these for the actual properties and types:
