A very nice thread around multi-threading in Delphi is evolving at Google Plus: Nick Hodges: Man, the chapter on Multi-threading is going to be seriously hard to write.….
Note: you need to be member of that G+ group to read it, but Nick Hodges allows most people in…

(I also tagged it XE8, as by the time such a book arrives, that Delphi version has most likely come out given the past release frequency <g>)

There is a nice Delphi memory thread at G+ initiated by Tommi Prami for which I added some links to the memory managers:
More interesting comments (most people seem to favour FastMM, as they can get very good performance out of it even in multi-threaded environments) at There have not been much of the Talk of MemoryManagers lately….
Note there is also TBBMM based on TBB, but it seems unmaintained.
Barry Kelly’s memory manager is based on Boehm-Demers-Weiser GC.

Earlie this month, I wrote a review about Delphi Cookbook.
Well: as of last thursday, you can get that for USD 5 (or EUR 4.80, so better get yourself a USA account: just ensure your address is in the USA).
Heck: until januari 6th, you can get any eBook or Video on Packt for USD 5.
Note there is even an x-Mas countdown on the way (with each day a free book that is readable/downloadable for 24 hours).
There’s over 2500+ books to choose from, so I’m grabbing this chance to learn a few things on OpenCV, Scala, and PowerShell.

After speaking on EKON 2014 and ItDevCon 2014, the last month has been extremely busy on both the work and family side of things.
So it took longer to write my review of the Delphi Cookbook by Daniele Teti, Packt publishing (ISBN 978-1783559586).
Before the review, first two ways to see for yourself if you’d like the book:
Daniele Teti has a Table of Contents on the page where he introduced his book, but that ToC is a bit poorly formatted, so I included a better formatted one below.
Some other reviews of the Delphi Cookbook also make an interesting read (I read them after writing my own):
Before the review a disclaimer. I bought the eBook version before Packt publishing asked for reviewers. They sent me a paper copy for free (which somehow took 2 weeks to arrive). I read about 25% of the book before the two European Delphi conferences, and the rest over the last two weeks.
I’ll try to keep this to the point, as too much detail would be killing. And I’m not writing a book here (:
So lets start with what I like:
I want to stress the last: Daniele Teti did an excellent job on this.
When writing a book or teaching material, it is hard to strike balances between the kinds and diversity of topics, the depth and order of the topics, and choosing between what to cover and how to cover it.
The way the chapters a built together with a variety of interesting topics per chapter, a great mix of chapters, and the various topics building (but not too much relying) on previously covered topics is really great. The whole book shows that Daniele is a great teacher. Well done.
Then a few things I dislike:
The dislikes are minor compared to the likes, so here is the…
I didn’t buy the book by accident: knowing the presentation and teaching style of Daniele, I was expecting a nice mix of topics explained in a light and fun way. The book surpassed those expectations by far.
So any Delphi programmer should buy this book. If not for using right now, then for getting some ideas, and reading the various topics later.
Below some suggested combinations for using this book various Delphi audiences.
Buy this book. It gets you inspired, even if only some of the topics are suited for real beginners. Then get the books below, read them and get back to the Delphi Cookbook for more inspiration:
Buy this book. Consider buying Coding in Delphi by Nick Hodges.
Also read Coding in Delphi by Nick Hodges.
I know few people that master all Delphi topics well (I’m not one of them: especially on the mobile side I’ve still a lot to learn). Even for gurus, I think this is a nice book, especially considering the price.

Every vendor should publish version numbers like this to make it easier for their customers to check if they are current or not.
I can’t promise to have a complete list, or the latest versions, but I will update with the versions I have used.

A long while ago, I posted a detailed answer on what functions the default comparers actually were calling to get a feel for if they would apply or not answering delphi – What does the default TArray.Sort comparator actually do and when would you use it? – Stack Overflow.
I needed that information recently because of some sorting issues I bumped into (sorting generic records), so finally a blog post.
First some links to documentation for even more background information:

Using Delphi build-events (see my post Delphi prebuild/prelink/postbuild events), you can automate the process of signing your Delphi executables with a digital certificate.
Below the steps for signing Windows executables.

Please someone add the Software on a String blog to DelphiFeeds (:
Great article on testing implementations of interfaces in a generic way. With examples in NUnit and DUnit.
How do I test an interface? Should I even do that? | Software on a String.
And then Stefan Glienke made a great comment at https://plus.google.com/u/0/+MarjanVenema/posts/Dgb8WADLwXZ making the DUnit implementation even easier:
But even if you go without that extra base class the cool thing is that you don’t need to restrict your classes to be a TInterfacedObject but specify the interface they need to implement (yay, compiletime type safety) and then you can get rid of the Supports call and directly assign the result of the ctor call to the sut variable.

Ever since the Delphi build engine got changed to MS Build in Delphi 2007, many people use Delphi build events. Their order is prebuild, prelink and postbuild (or maybe better spelled pre-build, pre-link and post-build).
Before Delphi 2007, you had to fiddler with project groups and dependencies to fake pre-build and post-build events. For an example see Pre and Post-Build Automation in Delphi.
One of the really good things about these events is that build events appear in the output tab of the messages window.
One of the really bad things is that there is hardly any documentation about the build events.
At least two important things are missing:
Let’s explain these. Read the rest of this entry »
