Have fun creating your own REST microservices and PWA‘s!

CodeRage 2018 – 4-6 December 2018

CodeRage 2018 is just around the corner!

The complete schedule:
https://www.embarcadero.com/coderage-2018

This CodeRage I’m showing you how to build microservices and how to consume them from desktop, Android mobile and using a HTML / JavaScript web app. The web app uses TMS WebCore and PAS2JS, but goes beyond basic coding as it also shows you how to convert the web app to a Progressive Web App, or PWA for short

The boilerplate code is of course available for download, please use it to jump start your own software.

Oh, and the nice thing about PWA, an Android device will offer the user the option to install the web app as an actual app with an icon on the start screen. Good stuff!

Register here, it’s free but infinite value for money:

Delphi 10.3 Rio

Delphi 10.3 Rio has been released today!

The most awaited new feature is of course support for Android 8 and 9. As you may recall Google made changes to its requirements for new apps in the app store. These requirements are now all met. Please remember to also use the new PermissionsService.RequestPermissions to request permissions for the app at runtime.

If you’re into nitty gritty details, the internal coding for parameters of methods has changed, allowing better compatibility between C++ and Delphi. What it boils down to is that for 64-bit code more parameters (between 5 an up to 8 byte in size) are now passed to functions using CPU registers, where they would previously be passed as pointers to the actual data. This speeds some code up quite a bit.

There are also some changes in the way that JSON is serialized. If you are using REST webservices with clients you may need to update both to Rio at the same time, to achieve interoperability. This mainly affects JSON serialization that internally uses RTTI. Its more efficient, but may break some existing code.

For the full list of new things take a look at http://docwiki.embarcadero.com/RADStudio/Rio/en/What%27s_New

Delphi Academy start volgende week

Delphi Academy is een geheel vrijblijvende en voor stagiairs, afstudeerders, scholieren gratis toegankelijk opleiding tot Delphi developer.

Delphi Academy LogoIn een eerdere meetup met Delphi MVPs hebben we het erover gehad. Zou het niet mooi zijn als er een open opleiding zou bestaan om je te scholen tot Delphi developer?

Delphi Academy is zo’n een traject, en in 3 maanden worden de deelnemers opgeleid tot junior Delphi developer. Lukt het je alles mee te doen, aan het eind weet elke werkgever; deze kanidaat weet al heel veel.

Je kunt echter ook gewoon deelnemen aan enkele van de trainingen of course en praktikum dagen. De trainingen zijn Open voor deelname vanuit het bedrijfsleven, de overige zijn voor Stage, voor stagiairs en afstudeerders of voor iedereen die affiniteit heeft met ICT en zich wil omscholen.

En ja, het is echt vrijblijvend, geen verplichtingen achteraf.

Doe je ook mee?

Visit to Alister Christie

While we where on vacation in New-Zeeland, Alister Christie kindly invited us over to stay at their house for a couple of days. We had a great time with Alister and Jackie, we absolutely loved our stay. Their patch of the world is also really something special. Alister also made some time for an interview, he really makes full use of each day. Did you know Alister makes some terrific wines at home? They where absolutely delicious. Hope to visit again sometime!.

We also organized some meetups with Delphi developers in Auckland, Wellington and Christchurch, which were great. Its fun to see such diversity and ingenuity in using Delphi in all kinds of software. On these meetups Alister presented on the PPL and I introduced the TMS Web Core. TMS Web Core can really be a game changer; as its very easy to get into web page based apps using this technology. They can also easily be made Progressuve Web App compliant.

It was great to meet all these nice people in New-Zealand!

 

Delphi Meetup Web Development bij TMS op 12 juni 2018

Het is al bijna zover, de volgende Delphi Meetup. Dit keer in Wevelgem op het kantoor van TMS Software.

Bruno Fierens laat zien hoe je vanuit de Delphi IDE, met de Delphi taal en componenten, op een een RAD manier web user-interfaces kunt bouwen. Ook zie je hoe vanuit die Delphi web applicaties op eenvoudig bestaande Javascript libraries, zoals bijvoorbeeld jQuery, gebruik kan worden gemaakt van user-interface controls. Als laatste laat hij zien hoe dit samen met Delphi databinding te gebruiken is..

In aansluiting op de sessie van Bruno combineert Danny Wind in een use case een aantal technologie├źn om je te laten zien hoe eenvoudig het is om gebruik te maken van RADical Web. Danny zal een op REST gebaseerde micro-service back-end gebruiken en een┬á front-end die zowel RADical Web als Apps (Android/iOS) gebruikt. En dit alles gewoon met Delphi Code!

Get your App in the Google Play store before August 1, 2018

Google is changing its requirements for the target SDK API level. Starting from August 1st any new app uploaded to the Play Store must target API level 26 (Android 8.0). If you have an existing app in the Play Store you’ll have some more time, as updates to the app must only meet this same requirement on November 1st.

This means that if you are currently developing a new Delphi Android App you should consider uploading it into the Play Store before August 1st. Why? The current version of Delphi uses a target SDK of API level 14. If you upload your new app now, this buys you some time until November 1st to become API level 26 compliant with an app update.

I’m working on an API level 26 issue right now, where I’m extending the JContext of Delphi with some of the new API level 26 features for starting a foreground service. This is needed to comply with the new background execution limits introduced in Oreo. This works quite well, and does not require a lot of code.

If you can not upload your app to the Play Store before August 1st, then this blog post from Dave at Delphi Worlds may help you further. It changes some of the Delphi code to achieve (partial) API level 26 compliance.

Delphi 10 Tokyo Update and Firemonkey-Android Power training March-2018

On March 8th and 9th we have the Delphi 10 Tokyo Firemonkey and Android Power training planned in Etten-Leur in the Netherlands. In just two days you will learn how to develop an Android App in Delphi, with high level features in the GUI down to high tech stuff when interacting with the Java side. This training is available in both English and Dutch. Registration can be found here.

A week after, on March 15th and 16th, we have the Delphi 10 Tokyo Update training in our agenda. As one of the previous attendees told me a couple of weeks after attending this training “I’ve learned so many new things in these two days; I especially liked the (PPL) TTasks chapter”. This one is only available in Dutch, registration can be found here. Note: due to a conflict in planning with an on-site training this open training has been moved to April 19th and 20th.
