It is already November—time flies these days. Despite the global pandemic, we keep charging ahead. As developers are getting more used to working from home (and some love it), we see more projects picking up, which is exciting. I am especially thrilled that there are more and more public Delphi projects on GitHub, and related discussions on popular platforms, such as Stack Overflow and Reddit, are growing, though not as quickly. I know that we have our own more proprietary ones, which are great, but the more Delphi we put out there, the better! My themes lately have been simple: Develop brilliant code. Share it. Inspire existing and new Delphi developers. Have you checked any of these boxes lately? There are about 8K Delphi projects on GitHub. Some 500K+ developers know Delphi, and at least 200-300K are actively developing with it. You do the math! We recently released Bold for Delphi open source to help contribute to the community, and a fantastic group of developers is now working on the project. Embarcadero is just getting started with open source projects, so be on the lookout for more! Here are some highlights of our current efforts: 10.4 was an essential release with over 1,000 enhancements and quality fixes. Many of its features were welcomed by both large companies and individual developers. 10.4.1 is a stable and robust version, featuring a faster implementation of Delphi Code Insight based on Language Server Protocol, VCL styles that work great with High-DPI and 4K monitors, extended Apple platforms, and API coverage. It also includes a much improved GetIt package manager and many other features. 10.4.1 adds over 800 quality improvements, including 500+ for issues publicly reported on the Quality Portal site. 10.4.2 Beta is also kicking off soon for Update Subscription customers. It is a great time to upgrade! With almost 4000 people registered, this was our biggest annual Delphi event. If you missed the live sessions, register now to catch the replays. This year we included many expert panels, including with some of Delphi’s lead architects, a massive hit with everyone! Join and enjoy presentations from thought leaders and check out some of the great perks and discounts available. One of our goals with DelphiCon was to simplify the format compared to previous CodeRage events and we hope you enjoyed it. We are always looking for ways to improve, and your feedback is valuable. By popular demand, a dedicated C++ event is in the works for the spring. Product management recently updated the RAD Studio roadmap for November 2020. Always great to see what the plans are for the future, and read the commentary from product management around these plans. These roadmaps are based on the direction of the industry, and the feedback we receive from you, our users. Check out the roadmap, leave your feedback, and file feature requests on Quality Portal. We realize that budgets are tight these days and want to make working with the latest releases more economical. We have a number of attractive global promotions to fit different needs. We have enhanced the Architect SKU to include a lot of value-added products, from Ext JS and Ranorex licenses to the expanded use of InterBase and RAD Server. If you are looking for the best dollar deal, that is clearly […]

We know how to do Multithreading in Delphi. How about a simple python script that performs threading in Python and runs the script in the Delphi application? This brings the advantage of using existing multithreaded or new python scripts in your Delphi application. This post guide you to do that with the Python4Delphi Sample app. You can also use Python4Delphi with C++Builder. Python4Delphi Demo22 Sample App shows how to create a Python script in Delphi Application which demonstrates creating thread and output the result in windows console, passing arguments in the command line. You can find the Demo22 source on GitHub. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi. Components used in Python4Delphi Demo22 App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a singleton class. You can find the Python4Delphi Demo22 sample project from the extracted GitHub repository ..Python4DelphiDemosDemo22.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property. It uses a Python Script file threading_test.py where the below list of modules was used. threading: This module constructs higher-level threading interfaces on top of the lower level _thread module.  collections: This module implements specialized container datatypes providing alternatives to Python’s general-purpose built-in containers, dict, list, set, and tuple. In this sample, deque is used. time: This module provides various time-related functions. threading_test.py contains, ProducerThread, ConsumerThread, BoundedQueue class within the function _test. Memo1, used for providing the Python Script to execute. On Clicking Execute Button the below code executes the python script. procedure TForm1.Button1Click(Sender: TObject); begin PythonEngine1.ExecStrings( Memo1.Lines ); end; procedure TForm1.Button1Click(Sender: TObject); begin   PythonEngine1.ExecStrings( Memo1.Lines ); end; The script below is executed which will opens a window console, create threads put in a queue and execute one after other. import threading_test import sys # the following is needed to use the newly allocated console! sys.stdout = sys.stderr= open(‘CONOUT$’, ‘wt’) try: count = int(sys.argv[1]) except: count = 3 for i in range(count): print (“**** Pass”, i) threading_test._test() print (“**** Done.”) import threading_test   import sys # the following is needed to use the newly allocated console! sys.stdout = sys.stderr= open(‘CONOUT$’, ‘wt’)   try:   count = int(sys.argv[1]) except:   count = 3   for i in range(count):   print (“**** Pass”, i)   threading_test._test() print (“**** Done.”) Head over and check out the open source Python4Delphi project which makes it easy to build Python GUIs for Windows with Delphi.

Miyazaki Prefectural Saitohara Archaeological Museum has built an app for smartphones, “Saitohara Archaeological Expo Navi,” which provides navigation in the museum, guidance on exhibits, etc. in multiple languages ​​using solutions provided by Embarcadero and Marubeni Information Systems. did. This solution consists of a power-saving beacon that emits radio waves (using “rapiNAVI Air2” manufactured by Marubeni Information Systems) and Embarcadero’s software development function “Beacon Fence” that detects the position using this beacon. At the Saitohara Archaeological Museum, you can use the in-house navigation system “Saitohara Archaeological Expo Navi” that utilizes beacons. With this system, you can check the current location of the museum on your smartphone, and read the explanation of the exhibits in front of you in four languages: Japanese, English, Chinese, and Korean. In this session, we will introduce how this system was built at the museum, along with an overview of the system and the features of RAD Studio / Delphi + BeaconFence used.
