Delphi Boot Camp add’s YouTube and Facebook streams to service demand.
Today was very exciting in the Embarcadero offices. Developers have been registering for Delphi Boot Camp in their thousands, with over 1000+ registering in the last weekend alone.
Having all this interested in Delphi is awesome, but also has raised quite a challenge for the team delivering Boot Camp due to physical viewing limitations in GoToWebinar. The decision was taken last week that we should add additional ways to stream this out to the 1000’s who were going to attend and Jim McKeeth started off looking into YouTube and Facebook streaming.
This morning, all attendees received an update email with the multiple streaming options included. During the first of the two live daily sessions we have seen huge numbers viewing on both Facebook and YouTube.
If you couldn’t get into GoToWebinar, either try the second session or watch the replay on YouTube later, keep an eye on community for the replays.
If you did watch the Boot Camp on YouTube, thank you to everyone who joined in with such fun discussions. (my personal favourite question was “So can I talk to Dolphins with this?” – I’ve seen some cool delphi apps, but that would be a nice hardware integration project) Please let us know what you think about these medias for the future.
You can also use the Starer Edition to qualify for upgrade pricing to RAD Studio or Delphi Pro / Enterprise or Architect editions. And with the mobile add on pack included along with the bonus pack, now is a great time to do that.
Visual LiveBindings is a technology that allows you to bind your data and objects (model) to the UI making. While LiveBindings is a key part of FireMonkey development, it is often overlooked by VCL developers.
A while ago I started a series of blogs on LiveBindings and how to use them with existing VCL applications. Covering seven blog posts, I looked at
Join Embarcadero experts and leading community MVP’s for 5 workshops from Monday 5th September to Friday 9th September.
Focusing on getting stared and using the FMX framework to create cross platform ready code, Delphi Boot Camp is a great way to learn new skills and ask leading experts direct questions on application development.
Introduction to Delphi: The IDE and Your First App
Getting to Know the Delphi Language
Building Effective User Interfaces with FireMonkey
The final part of the Boot Camp is the programming book! Delphi is the home to modern Object Pascal programming and you can get up to speed with the modern Delphi / Object Pascal language with the help of Marco Cantu’s awesome handbook.
The IoT Award Winning database InterBase, has for a long time supported the ability to store data in an array field type. This was originally introduced as a new field type to reduce API calls and speed up data write time for a specific Boeing project many years ago. Writing each value into an array can also simplified the data model as well as benefiting database performance.
While array field in InterBase have been around for a long time, they have not aways been that easy to access from the components layer reducing their adoption.
Accessing the Address Book on iOS and Android is a common request for many developers building line of business applications; quickly followed by “and how do I dial a phone number from code“. In this post I will explore how to explore the mobile Address Book using a common code base that works on iOS and Android using TAddressBook. (list to samples and documentation at the bottom of this article)
The TAddressBook lives under Services section of the tool palette and consists of two and has very little in the way of Component properties. It does however have two events that are very useful, and a number of run time methods to call.
The two events provide notification when the address book has been changed (outside the application) and the result of the application asking for access to the address book.
I’m currently working on a new blog post showing how to integrate a popular REST API. One of my tasks is to convert JSON to Delphi Objects, so I need to define the Delphi class structures to work with so I can use the TJSON.JSONToObject that I covered previously. I decided to see if anyone had done work to convert JSON into Delphi classes.
The JSON to Delphi Project is a Delphi FMX application that has a simple UI that allows you to modify the automatically created JSON class names which is pretty useful and the code worked first time when copied into my sample. (although I have more playing to do)
The JSON to Delphi tool is definitely a useful resource to work alongside the REST Debugger that you can find in the BIN directory of your RAD Studio install.
On the whole moving to 64bit (on iOS or Windows) is beautifully simple to achieve! It can be just as simple as adding the Delphi 64bit Windows target platform in the project manager and rebuilding the project.
My experience from talking to many developers who have moved up is that normally there are a few things to check in your code but typically its not a massive task to get compiling and ready to test.
A lot has been recorded on moving from Windows 32bit to Windows 64bit Delphi and this should be a useful summary if your just planning now moving up from older versions of Delphi to Delphi 10. If you are building iOS applications, then you will need to use the 64bit build now to get into the AppStore. Thankfully, Delphi has made the task of using 64bit very simple across all platforms and protected us from the headaches non Delphi Developers have had on the whole.
Lets start with this short video from David I who covers some the foundations in 7 minutes!
We (geeks) should all know that applications that run in memory run faster than those that have regular disk I/O.
Having more of the data processing in memory has a positive effect on speed and performance, however its not without risk. As memory is transient, you are always at risk of data loss if the data in memory hasn’t been saved to disk (which is where you get the disk i/o speed degradation again.
InterBase brings together the speed of in memory data processing with the security of immediate disk I/O with InterBase Journaling. The write ahead logging enables InterBase to securely log the write transactions to the journal making the best of both worlds possible.
