We create tutorials. And all this without the usual stuff. We want to show how you can work with FireMonkey. Our tutorials are not available as source code. We want to show you a look more, and yes, we do it. Fast, reliable, targeted, unambiguous and ahead of its time. We love Delphi with FireMonkey. #ILoveDelphi

From a quick scan for LogAllocatedBlocksToFile, I found these links I need to dig deeper into:
This in oder to spot “leaks” at run-time that are being release at process end, but build up memory usage over time. Some might call them “live leaks”.
Basically this is a technique I used a long time ago when I wrote a memory allocation dumper and parsing tool combination in the Turbo/Borland Pascal era called “Korsakov” (I might even have updated that to Delphi 1 once, but soon in Delphi better tools became available).
Another tool that might help here is [WayBack] GitHub – yavfast/dbg-spider: Spider – Delphi profiler with docs at [WayBack] Spider – Delphi profiler:

Don’t expect high floating point performance of the Delphi for Linux compiler as this thread proves it is not: [WayBack] Based on a recent post here, it looks like the new Linux compiler uses the x87 unit for floating point. Naturally this won’t perform well. If it is true… – David Heffernan – Google+

Does anybody know a shorter, more permanent solution for [WayBack] RAD Studio 10.2.2 Annoying New Features. Help? – Forum – Embarcadero Community.
Especially the first one is very important to me.
Ever since Delphi introduced IDE layouts, it would remember the last one selected. With Delphi 10.2.2 Tokyo not so any more: it ALWAYS starts with an imposed “Startup Layout”. If you delete it, it re-appears.
I have a carefully named set of layouts that depends on the monitors I am using.
The workaround – every time I switch monitors, at least a few times a day, especially when moving between places, for instance for meetings – is this:
Then each time I tweak a layout, I have to remember to save it both as “Startup layout” and as the actual named layout.
The really dumb thing is that RSP-20138 Can not define default Startup layout is classified as
“Jira-Quality Sync Service added a comment – 29/May/18 2:50 AM
Issue is reclassified as ‘New Feature'”
Via [WayBack1, WayBack2] So Embarcadero broke the “Default layout” (now always enforces a new “Standard Layout”) upon IDE startup in 10.2 Tokyo, and commented on the bug report … – Jeroen Wiert Pluimers – Google+ which has quite a few nice comments and links, including:

Problem (D2007 and up)
If you are starting your Delphi VCL app meanwhile your mouse is moving, no accelerators are shown (Menu, button, focus rect missing… etc.)
Something similar happens when you click on a button which opens a new form, somehow UI State becomes a state which is wrong.
Solution
In a detoured Form.DoShow(Or in every OnShow event) :Self.Perform(WM_CHANGEUISTATE, MakeLong(UIS_CLEAR, UISF_HIDEACCEL or UISF_HIDEFOCUS), 0);
- No repaint penalty
- no flicker
- accels
- focus rect are always shown
- system is not touched.

On [WayBack] Delphi Community Edition available: – Uwe Raabe – Google+, the links to the [WayBack] EULA, [WayBack] FAQ and [WayBack] Feature Matrix were shared.
In summary (read the G+ thread for more), the Delphi Community Edition is a web-installer of version 10.2.3 feature equivalent to the Delphi Professional Edition.
I think it is a good move to make Delphi more accessible to many more people.
A few restrictions apply, for instance there is also a C++ Builder Community Edition equivalent to the C++ Builder Professional edition, but you cannot install them on the same system at the time time.
Also, you cannot move around the command-line compiler to a different system (for instance a build-machine for Continuous Integration purposes).
The financial restriction that applies can be summarised as this: When the revenue you make during the year exceeds USD 5000 you have to stop using the Community Edition license.
Note that this is about revenue, not about income (which many define as “net of revenues and expenses”), and does not mention the revenue source, so watch this during the years you use the Community Edition.
Furthermore, Embarcadero indicates they collect information about your use of the Community Edition, but the [WayBack] privacy statement is not clear how.
All in all I hope this move attracts fresh people into the Delphi community.
The heise – the German flagship IT journal – likes it too: [WayBack] Delphi und C ++ Builder als Community Edition | heise Developer (via [WayBack] Some nice PR … Embarcadero-konfektioniert-Delphi-und-C-Builder-als-Community-Edition-4115563… – Roland Kossow – Google+)
Yes, Embarcadero is going after your employer if you register Delphi Community with a corporate email address.

Hopefully my blog will last longer than the original delphi.about.org articles.
Last year, I noticed yet another path into bit rot: [WayBack] The title reads “Source Code for the TColorButton Delphi Component”… I must be going blind because I can’t find it – Thomas Mueller (dummzeuch) – Google+
In this case, http://delphi.about.com/library/weekly/aa061104a.htm got redirected via http://delphi.about.com/od/vclusing/fl/Source-Code-for-the-TColorButton-Delphi-Component.htm to [WayBack] https://www.thoughtco.com/source-code-for-tcolorbutton-4077901 which is a copy of the original article failing to preserve the download links of the original source code.
It doesn’t help that the original source download at http://delphi.about.com/library/code/ncaa061104a.htm also redirects to https://www.thoughtco.com/delphi-programming-4133475 a generic catch all of [WayBack] Delphi Programming where http://delphi.about.com also redirects to.
In other words:
http://delphi.about.com got hi-jacked.
So here are some links to various forms of that source code:

An interesting discussion sprouted from the bragging [WayBack] Did you know the IDE starts almost twice as fast in 10.2.2 as it did in 10.1? https://community.embarcadero.com/blogs/entry/new-in-10-2-2-welcome-page-… – David Millington – Google+.
I do not care very much about IDE start times (Visual Studio starts faster, others like Android Studio start slower than Delphi), more about productivity.
Which means loading projects, opening files and forms, switching projects, etcetera need to be fast and stable.
For me this is when on Delphi projects, I start about half a dozen copies of Delphi about 10 seconds apart (otherwise you get exceptions in any Galileo version), make some tea, then come back.
Each time an IDE crashes, I kill it, start a new one, switch to an existing one, load the projects I need and continue. On a full day working with Delphi, this happens about a dozen times a day.
After that I want to be productive.
Here is where I was so surprised by the great tip from Yusuf Zorlu
+Asbjørn Heid you should try to disable all “livebinding” packages + rename dclbindcomp250.bpl . If i opened a form before i had to wait 20 to 40 seconds … now it is superfast and opens forms under 5 seconds. I don’t need LiveBindings …
and the response by Asbjørn Heid
+Yusuf Zorlu Thank you! Holy cow that’s a difference! As you say, even our most complex forms are down to 4 seconds now.
I never use LiveBindings as they are way to convoluted, unstable and result in logic being in designers as opposed to tool-manageable code.
In addition, LiveBindings have never been really optimised since their inception in Delphi XE2.
This saves a lot of time!
So one day, I need to update Source: Delphi packages I have disabled by prefixing their description with an underscore (and why) and create a batch file with the various [WayBack] reg add commands modifying the package loads.

I totally forgot about [Archive.is] GExperts Help: Set Component Properties
The main reason is that I hardly use any live connections in Delphi applications any more for mainly two reasons:
But once every while I’m on a new site that has their own tool-chain installed and I see screens like this one:
The good thing is that it can bring certain components into a know state before compiling your application.
But this is a thing your CI environment should already do for you.
