I wanted to spotlight a recent return to the Delphi community as an MVP: Dr. Holger Flick. He’s started blogging again and hasn’t slowed down producing good quality technical content.
Like many of us, Holger started programming with Turbo Pascal and GW Basic. For him it was at the age of 7 (with Basic) and switching to Delphi 2 at the age of 14. In 2003 he became very active in the forums and was a member of Team Indy. During that time he was blogging at “Holger’s Thoughts on Delphi,” and also wrote several articles in German and Dutch Delphi magazines.
Holger even spent some time freelancing for QA at Borland and CodeGear. Later for Embarcadero he reported bugs on the localization in German. He also freelanced on the Borland and CodeGear Developer Network. Eventually he earned a place on the Delphi 2005, 2006 and 2007 credits screen (Help > About press ALT key and type TEAM.)
Holgar regularly spoke at conferences on Model-Driven Application Development, ECO (Enterprise Core Objects), and ASP.NET (with Delphi for .NET naturally). I met Holger in person in San Jose at the Delphi Developer Conference in May of 2009, and again in Las Vegas at the Delphi Developer Solutions Conference in 2011.
Holger studied Computer Science at Technical University of Dortmund, Germany, and earned his Ph.D. in Engineering at Ruhr University Bochum, Germany. He then founded his own IT consulting company in 2011 before joining Korfmann Lufttechnik GmbH as head of IT. Now with his company Flixments, LLC. and new brand Flix Engineering he is blogging about Delphi development again. As an Embarcadero MVP I’m sure his professional skills will be a huge benefit to the Delphi community and IT landscape in South West Florida in general.
Holger says it was hard to find a recent picture of him without sunglasses as they are pretty much required in Florida.
Join me in welcoming Holger back to the Delphi community as an MVP!
Tried something new where I went over the current issue of Blaise Pascal with Detlef Overbeek. The video is available on YouTube.
INTERVIEW WITH ATANAS POPOV
Atanas agreed after being asked immediately to be interviewed. That was about two months ago. About two weeks ago there was quite a lot of turbulence in the community and vendors went nervous, some people even saw some kind of armageddon for Delphi. Even the more reason to talk the new Chief, ask him all the questions about their new policy, what is going to happen to and with Delphi. An explanation sometimes even in detail follows in the magazine.
CREATE AND TRAIN YOUR FIRST NEURAL NETWORK
BY BOIAN MITOV
The quest for intelligent machine has started long before the first computers became reality. For centuries mechanical devices have been created to mimic human behavior, and grab the imagination of the spectators with the promises of mechanical intelligence. But only after the first electronic computers appeared, creating such intelligence became feasible.
The first attempts at such intelligence were focused on teaching the computers to play games and solve mathematical problems. They have proven fairly good at both tasks. However when an attempt was made to connect a camera to a motorized cart and have a computer navigate it through a room full of obstacles, it became apparent that such simple task represents a major challenge to the computer, and so began the quest for creating the intelligent computer.
HOW TO BUILD AN APP IN XML AND
CREATE AN ANDROID PACKAGE
INCLUDING HOW TO USE THE EMULATOR
with code and working APK
BY DETLEF OVERBEEK
In this article we will create a Multi Device Application on an emulated android device.
We are going to use the Multi Device Application we also used in Issue 4 2016 ‘How to build an app in xml’.
We also show where you could find the information to use any of your devices to run a Multi Device Application. How to do this varies per device so we can not explain it fully within the scope of this article. However we hope to point you into the right direction by showing how to do it with a Samsung S5 -android version 5.0.1. and for the emulator we chose for the NEXUS 6 -because it seemed to be a smaller item and that might run faster…
Here is part 1 of my supplemental list of great software developers. It is in no particular order, and is of no particular magnitude. It is rather arbitrary. Part art, part science, a lot like software development.
Let’s start with Martin Fowler. He is probably most known for his book on refactoring, which he co-wrote with Kent Beck, John Brant, William Opdyke, and Don Roberts. I don’t think they invented the idea of refactoring code: a controlled technique for improving the design of an existing code base. But that book really did a lot to promote the idea or refactoring and testing, and also to define related concepts, including the code smells that suggest a refactoring may be necessary. There have been a lot of books on refactoring since then, but this is still the authoritative tome in my mind. Fowler is also a proponent of software design and agile methodology. He was one of the original “signers” of the Agile Manifesto.
Alan Turing, OBE FRS
How in the world did I miss Alan Turing in my first list? Clearly an oversight on my part. While Ada Lovelace was the first Computer Programmer, Turing was the first Computer Scientist. He’s design of a “universal computing machine” became known as a “Turing machine” and is the fundamental basis for computers today. It lead to the idea of a programming language being “Turing complete” as being theoretically capable of expressing all tasks accomplishable by computers. His name was also lent to the “Turing test” which invented as a way to test machines that exhibit intelligent behavior.
One of Turing’s greatest contributions was one that he was not known for because it was kept secret. He was instrumental in the cryptanalysis of the Enigma cipher during World War II. This is a photo of me using an actual Enigma machine at the NSA museum in Maryland, USA.
Would you like to play a game? Chances are you are familiar with Carmack’s work in game development. He was the lead programmer for id software’s Commander Keen, Wolfenstein 3D, Doom, Quake, Rage and their sequels. Currently he is the CTO for Oculus VR, Inc., the folks that are making the Oculus Rift Virtual Reality headset.
Carmack was originally attributed with coming up with the Fast Inverse Square Root, a piece of mathematical black magic to approximate an inverse square of a 32-bit integer 4 times faster than using floating point math. While that one turned out to originate elsewhere, he is responsible for a number of innovative technologies that are common in many games.
Shannon was more of a mathematician, electrical engineer, and cryptographer, but he is also the father of information theory, which has a huge impact on computer science. He met turing in 1943, and discussed his Universal Turing machine as many of its ideas complimented Shannon’s own.
Shannon had many inventions and contributions, but possibly one of his greatest is the Ultimate Machine: A simple box with a single switch. When the switch is flipped, the box opens and a finger reaches out to flip the switch back, retracting the finger and flipping the switch back. Although the flame-throwing trumpet is a close second.
Shannon also co-invented the wearable computer and used it to make a fortune counting cards in Las Vegas. His technique inspired the book Bringing Down the House and the movie 21. He later applied the same technique to the stock market with even better results. Shannon is one of those people that the more you learn about the more he sounds like a myth or a legend.
This isn’t a complete list. I’ve got more to cover, but this is enough for now . . .
I’m sure you’ve all visited FMXExpress.com, if you haven’t then I’ll just let you go there now. Eli is joining us for the C++ Boot Camp this week and is presenting on Thursday with coverage of game development with FireMonkey. He is showing off 4 different FireMonkey games that run on Android, iOS, macOS and Windows. The cool thing is some of the games have features where you can view the game on device while you control it on the other.
Eli currently manages a team of about 25 independent content creators, schedulers, and developers through UpWork. The content team handles over 30 Facebook pages reaching an audience of tens of millions of users. He has been hiring through UpWork since 2012 and has paid out hundreds of thousands of dollars on hundreds of contracts across many different projects. Through his writing on FMXExpress.com Eli has reached over 300,000 developers interested in Delphi FireMonkey with over 600 tips and tricks articles. Additionally, over the years, he has deployed over 300 games to the web, Android, iOS, and Windows and aggregated 80,000+ flash games which have reached over 120+ million players worldwide with 215+ million gameplays. He is a full stack developer and entrepreneur who has also developed and deployed various trialware, freeware, open source, and server softwares with Delphi and many other technologies that have reached millions of users on the desktop.
When not being a business and development rockstar, Eli likes to travel.
You can find Eli all over the web and social media, but here are a few very cool sites to check out . . . .
Samuel “Muka” David is a Certified Delphi Developer since version 7 and a Certified Delphi Master Instructor. He specializes in software construction and building components. He loves Object Oriented development and is addicted to refactoring and agile techniques. He is always in search of perfect technique, following development teachers to acquire more knowledge in the art of programming. Delphi official instructor in RS by Aquasoft. Speaker at numbers Delphi Conference and one of Delphi Users Group coordinators of Rio Grande do Sul (DUG-RS). Also a lead instructor for the Extreme Delphi events all over Brazil.
I’ve met Samuel 3 times while visiting for the annual developer conference in Brazil. One thing he does to make things memorable is creating his talk around a move theme or some other external influence. In 2014 he was dressed as a Ghostbuster and did Bug Busters. Here is picture I got with him, Marco Cantu and my flaming hair.
He also creates matching promotional posters for the conference . . .
Not only is he a master Delphi developer, he is also a master with Photoshop, creativity and costume design. He makes all his outfits himself, including the cool Delphi helmet patch on his shoulder above. Here he is dressed as Indiana Jones in 2013.
If you live near Brazil then I encourage to to plan on attending the 2016 Embarcadero Conference there. Not only will it be filled with great developer technical content, but you’ll get to meet all the great Brazilian MVPs and see what Samuel is dressed as this year.
In 2015 he was dressed as a member of the Elite Squad, although he isn’t wearing his beret in the picture above.
Are you fond of wrestling, sumo or other fighting games? You should surely try SUMOTORI DE CHU app. Inspired by Japanese national sport SUMO; it is a competitive full-contact sport where a wrestler attempts to force another wrestler out of a circular ring. It is an amazing minimalistic network game for two players.
It uses Wifi to synchronize the position, score and sound on a local network. Users can update their player image by taking snaps from their camera which will automatically get updated in the other player profile as well. Players can control the motion by tilting their device in the intended direction. This unique game also senses the physical motion of the user and this makes it able to control the motion in the game by those physical movements.
It is not just tilting the mobile device that makes the wrestler movie, but for acceleration you need to make big movements. The simplicity, physical involvement and the realistic touch to this game makes it a great contender for the cool app contest.
Usage of technology to develop the app:
This game is designed using Delphi and it is aimed for iOS and Android devices. It used some of the best Embarcadero product features such as FMX Application Platform, App Tethering, Box2D, Sensor manager for the gyroscope, Motion sensor for the accelerometer, component Camera (accessed through an action), and JSON. To enable running simultaneous audio files it uses free Game Audio Manager Class provided by FMXexpress.com.
