Another week, another critical update …
There was a logical error – also known as “my own stupidity” – built into OTL 3.06 which prevented programs that used OtlCommon to be started on Windows XP. This is now fixed.
There’s also a tiny addition to OtlSync included in this release.
There was a nasty bug in DSiWin32 unit included with the 3.06 release so I had no other option than to quickly issue a fix. If you have downloaded version 3.06 then please update to 3.06.1 as with 3.06 you could experience weird crashes during program startup. I’m really sorry for that :(
There’s also a tiny addition to TOmniValue included in this release.
Hi, guys! After a looong time, a new version of OmniThreadLibrary was released! It is available as a zipped download, git checkout, via Delphinus and (really soon) via GetIt.
Following stuff was added/changed/fixed since the 3.05 release:
For the last year and some, Sean B. Durkin has been working on the mobile port of the OmniThreadLibrary. There was lots to be done, as OTL was never designed to be a portable library – after all, it was created in Delphi 2007 times.
Recently I merged his latest commits into the mobile OmniThreadLibrary branch. This version is (by his words) functionally complete (although it may be missing some very recent OTL features) but is very much untested. So Sean is asking everybody that is interested in multithreading on OS/X, iOS, and Android to help him find bugs and to make OTL even more awesome!
Please report any findings to his OmniThreadLibrary-For-Mobile-DevelopmentProject on Google+. I am currently working on other aspects of the OTL and didn’t I put much energy into checking his work.
In case you are wondering which of the many github (and even bitbucket) omnixml repos is the official one (as www.omnixml.com is still pointing to the old googlecode storage), this is it: https://github.com/mremec/omnixml.
www.omnixml.com should be pointing to the correct repository “real soon now” ;)
In case you are already using RAD Studio Berlin 10.1 or are merely looking into it, these links and notes may help you.

Next week (Wednesday 25th) I’ll be presenting the new and shiny 10.1 release in Ljubljana.
For more info click here.
Next Wednesday (9th) I’ll be holding a presentation in Ljubljana. Topic: defensive programming, maintaining a clean code, and debugging tips and tricks. Presentation will be applicable to both Delphi and C++Builder programmers.
As usual, I’ll be presenting in Slovenian language.
Recently, I had to find bottlenecks in one of our applications that does all sorts of things related to DVB and is handling real-time reading and sending of data streams over IP with bitrates up to 80 Mb/s (in our lab; in real life maybe even more). Our customer created a configuration which essentially brought the app to the crawl and I had to fix it.
It quickly turned out that although the program was not able to handle the load, the CPU was not very busy. The busiest core was only using about 30% CPU. So I suspected the thread contention problems in FastMM, switched it for SapMM and indeed - the problem went away. CPU load went up and application could again handle the load.
Crisis averted, I took time to find the real problem - excessive get/freemem calls in this program. As far as I could tell, there existed no tool to find that so in a true DIY manner I created my own ;)
The materials for my “Connect your applications with REST” workshop are now available online (in Slovenian language).
Below you can find all the interesting DELPHI- and REST-related links I have collected during the preparation of this workshop.
My CodeRage X session on parallel programming with patterns is now available on YouTube.
Each time I have to record a webinar, I have trouble remembering how exactly did I do it last time, so I decided to document my workflow. Maybe this will help somebody else besides me …
If you have any ideas on how to improve my workflow or if you have a different way of solving same problems, then please post it in the comment section. Thanks!
[v 1.01: Added screenshots of CamStudio and Filmora settings and few words on Audacity settings.]
[v 1.02: Added appendix A with some time&space information.]
During the Q&A part of my Simplify Parallel Programming with Patterns presentation on CodeRage X, I’ve promised the listeners to publish a demo for updating a progress bar from a parallel for loop.
In this article I’ll try to explain few different approaches that all solve this problem. I’ve also put together a demo project which demonstrates all techniques.
Firstly, thanks to everybody who visited my RAD Studio 10 Seattle presentation! I’m sorry I had to improvise because of bad video drivers, but on the other hand RAD Studio performed great!
Secondly, here is a bunch of links I’ve promised.
My short spotlight presentation about high-level OmniThreadLibrary patterns is now available on YouTube.
EDIT: Make sure you read this post to the very end!
Are you developing a code that must work in different Delphi versions? Are you sick of writing code like
{$IF CompilerVersion >= 22}
class function Mapper<T1,T2>: IMapper<T1,T2>;
{$ENDIF}as you a) never know when some feature was introduced into Delphi and b) constantly wonder which version of Delphi has CompilerVersion equal to 22?
Then maybe you could use this simple include file.
Next Thursday (24th) I’ll be presenting new RAD Studio 10 Seattle in Ljubljana. This is announcement for Slovenian readers.
Naslednji četrtek (24.) se mi pridružite v kristalni palači na predstavitvi novega RAD Studia 10 Seattle, ki je po mnenju mnogih (in tudi mojem), ena boljših različic tega programskega orodja v zadnjih letih.
Predstavil vam bom izboljšano podporo za Windows 10 (v VCL in FMX), nove vizualne gradnike, izboljšave v IDE, novo podporo za mobilna okolja (razhroščevanje iOS 64-bit programov, pisanje sistemskih storitev za Android), novosti in izboljšave v sistemskih knjižnicah RTL, pa tudi novosti v prevajalnikih za C++ in še marsikaj.
Več podatkov o dogodku najdete tu.
