Including GradleWrapper.properties in each Gradle project follows the best practices: If you want to be sure your Gradle projects build in a year or two then make sure to always include the GradleWrapper and exactly specify the Gradle version!
PALO ALTO, Calif. - Oct. 20, 1999 - Sun Microsystems, Inc. today announced it has acquired NetBeans Ceska republika a.s., a Czech Republic joint stock company (NetBeans), by means of an asset purchase. NetBeans is a leading developer of cross-platform Java-based integrated development environments (IDE). NetBeans IDE products combined with products from Sun's acquisition of Forte Software, Inc., also announced today, will provide the million-plus Java Development Kit (JDK) software customers with software choices that range from entry-level offerings for individual developers and students to enterprise-class offerings for team development. Sun will also provide customers with the expert consulting and support services they need to dot-com their businesses.
Nashorn, the so far default JavaScript engine of JDK got deprecated in JDK11. What are you going to do? Freak out? Jump out of the window? Switch to Rhino? Give up on Java completely and use NodeJS? No, use Graal.js! Here is how:
Don't hesitate and make the switch! ApacheNetBeans has just switched today!
Go is great. Are you seeking a low level OS language? Heard about Go & its benefits? Convinced, or just interested, and still searching? If the latter: Have you considered Java? Because OracleLabsGraalVMNativeImage turns Java into a system language!
Stefan asked who shall be responsible for integration in the MultiGitRepository setup? Should there be an integration guy? No, its 21st century and we know how to use Git, right? The right tool is called pull request!
Turns out that one gets very useful MultiGitRepository#Appendix_A:_Local_Collaboration_Area: the master branch in each slave repository of the MultiGitRepository setup is in fact the best place for team members to collaborate without publishing the changes to the final integration destination.
Let me introduces MultiGitRepository - aka Git on steroids to you. I have seen a lot of confusion when it comes to working with multiple repositories and keeping them in orchestration, but I believe it is not that complex. Everything we learned about distributed version controls applies. However this time it has to be applied on a completely new level!
Admins! DevOps! In a recent StackOverFlow developer survey the NetBeans IDE has been rated at 10.9% for Mobile Developers and 8.4% for System Admins/DevOps. It is weird, but it supports the feeling I had for a long time: NetBeans is the IDE for DevOps!
In need of compiling Java ahead-of-time? See jsonparse example showing a Maven project that can turn your Java code into self-contained, small (less than 5M) and effective code suitable for your microservice or lamda as a service setups. Thanks to SubstrateVM!
I have to admit I am currently at a midlife crisis. I dedicated my last twenty years to promotion of a proper API design. I wrote TheAPIBook, I tried to propagate the principles of goodAPIDesign and modularity wherever I could. However I am tired...
Because it is always the same. Why do I have ask: where is your Usecase? What this method is good for? What do you actually want to achieve with this method/class/type? Have you considered the difference between APIvsSPI aspects of your design? Do you have a unit test? Is your proposed change BackwardCompatible? Do you have an evolution story for your design? Is your solution optimized for your comfort or comfort of users of your API? And so on and so on... People should read TheAPIBook before attempting to design an API, but they don't and they make the same mistakes again and again.
I got so disgust that I feel sick, physically sick, when I have to think about API design. Last weekend Toni asked me to review an API he is creating and showed me what he has. I starred at him, then at the code and at him, etc. for three minutes before I could say a word. Then I had to apologize and describe my current MidlifeCrisis.
When I look at an API these days, all I see is the wasted potential the API could have, but it doesn't and never will, because the amount of investment I would have to do to educate the API stakeholder is so huge, that I just don't want to make it.
Anyway, if you have an API that you'd like me to improve, let me know. If I see real interest in proper API design my disgust and MidlifeCrisis may go away...
Once you survive it and get to 5th minute, you'll also see interesting demos showing how fast the GraalVM and Truffle can be. Thanks again GeeCON guys for giving me a chance to speak at your keynote.
AutoUpdate is a fine NetBeans technology that can help you distribute things may see non-distributable. Here is a small demo that shows how one can fix broken NetBeans 8.1 installation.
This shows how extremely portable applications written with Html4Java APIs are! In fact you can write your application code first and because it is completely independent from the UI, you can completely revamp the UI later.
Isn't this the flexibility we always wanted? Read the whole story...
My MineSweeper application available from AppStore is gone. Apple wants me to pay remedies every year! For what!? Apple has no cost distributing my application. I am giving up. If somebody wants to distribute my MineSweeper, please go on, but I am giving up - giving up on Apple.
HTML/Java 1.3 comes with many improvements that will make your life easier and enlarge the options you have when mixing Java and HTML. Let me quote the Javadoc:
Model classes can have per-instance private data. Model classes can generate builder-like construction methods if builder prefix is specified. Property.mutable() can be false to define a non-mutable (almost constant) property. That in case of Knockout bindings means: the property is represented by a plain value rather than an observable in the JavaScript object. The JavaFX presenter can be executed in headless mode - just specify -Dfxpresenter.headless=true when launching its virtual machine and no window will be shown. This is particularly useful for testing. OSGi headers are now enterprise OSGi ready. Switched to minified version 3.4.0 of knockout.js. Better support for recursive @Model definitions. New module org.netbeans.html:xhr4j provides implementation of Transfer with technology identifier xhr4j - this module can be used to workaround limitations of CORS by handling the OnReceive connections in Java.
Today my colleagues from NetBeans noticed that my website - wiki.apidesign.org is under attack. Yes, since Jan 16, 2015 there were more than 5000 randomly modified pages. Maybe my talk in Grenoble was so popular that it attracted that much attention!?
Anyway I had to revert back to older copy of the database and re-apply my edits manually. Not everything looks the same as it did before, but hopefully no texts are lost.
In any case, I disabled ability to edit the pages. If you want to talk to me, use twitter and reference my handle: @JaroslavTulach
Bck2Brwsr version 0.17 is faster. Ten years ago nobody would imagine dynamic languages could get as good performance as they have now. The feeling that JavaScript just can't be fast is presumably present in many of our souls. The truth is, it can be relatively fast - not as fast as Java as my experiment with Sieve of Eratosthenes shows, but pretty damn fast. Certainly not an excuse to be ten times slower than HotSpot (which was the previous state of Bck2Brwsr).
The daily work on Truffle compiler team and the time I got when traveling from Snowcamp at Grenoble gave me a chance to speed Bck2Brwsr up. The sieve being a nice - e.g. small and focused - benchmark. Originally the algorithm couldn't be finished in a reasonable time when running on old version of Bck2Brwsr, but knowing what optimizing compilers seek for, it was relatively easy to speed it up ten times.
With great pleasure I announce that Bck2Brwsr, the most complete JavaVM in browser (that can run Javac as shown by Dew project) has been sped up many times being at most three times slower than HotSpot. Given the primary goal of Bck2Brwsr is modularity and not speed, I consider it a good sped up even knowing there is a room to make it even faster.
In September 2015 I decided to update the MineSweeper on AppStore to version 3.0. With a great pleasure I can announce that now, on December 18, 2015 the version is alive! Why it took so long?
Well, Apple's itunesconnect website is unusable - it isn't enough to upload new version of your application and press button Request Review. The user interface is completely messed up and hidden to make the process as obscure as possible. As a result MineSweeper was laying on the AppStore for six weeks before I found the right address (also pretty hidden) to complain at and was explained what is wrong.
Then, of course, the usual reject. This time it was due to Using images that resemble(!) Apple logo - yes, the MineSweeper is using Safari and iOS icon (check the on-line version). But these icons were present in the previous AppStore version as well. And version 2.3 was approved! Clearly the whole review process suffers from the human factor of the reviewer. What some reviewers find appropriate isn't appropriate for others.
How can I know this is a human factor? Because the new version of the MineSweeper of iOS comes with three translations - English, Czech and German (thanks to Toni) - and I am sure the reviewers checked just the English one. If the check was automatic - e.g. some scan through the binary - my submission might have been rejected again. Thankfully it wasn't. It is great we made it before Christmas, as next week the whole AppStore team is going for a vacation...
OracleLabs has a team in Czech Republic and is looking for new candidates to expand it. Innovation is feeding us, but that doesn't mean you have to be a scientist. We have enough clever people - we need also somebody to work!
Speed of Ruby has never been great. There were many attempts to improve it, but none delivered on its promise. All failed, but one! JRuby implementation running on top of JVM spiced with a bit of Truffle and Graal is in fact ten times faster than standard Ruby version.
I'll be speaking at JDD in Krakow in middle of October. In case you have a Java related message to deliver to the JDD galaxy, leave it here. I'll do my best to deliver it.
Cross platform UI library called HTML/Java API (which is developed by the NetBeans project) is proud to announce that version 1.2 has just been released on Maven central. See javadoc to find out what is new in this version!
The project is also glad that binaries of the new HTML/Java version 1.2 are now included in forthcoming NetBeans 8.1 release making it easy to develop wizards as well as components and dialogs in a cross-platform manner (e.g. able to run in NetBeans platform applications, IDE, Eclipse RCP, plugin-less browser and thanks to adoption by DukeScript project also on iOS and Android).
HTML/Java API is the heart of Java that is written once, and displayed everywhere!
Truffle - a modern way to write AST interpreters - gives you not only speed, but also debugger for free:
The picture shows NetBeans debugger stopped in middle of simple language (an artificial language used for demo purposes) method. NetBeans knows nothing about simple language (that is why syntax coloring is missing), but as NetBeans understands the TruffleAST, it can still provide enough valuable information in the debugger.
Please note that the name of the method is properly recognized and shown on top of the stack. Variables a and b and their values are properly shown as well.
Designing your own language? Do you want to spend time writing a debugger? If not, use Truffle and you'll get your debugger for free!
The original name of the project was Xelfi and it started at MatFyz faculty of Charles University in middle of 90-ties. However it was so successful that it had to turn into something as successful as NetBeans. In case you are satisfied with your IDE, consider reading about its root...
Since Sep 15, 2014 the MineSweeperNetBeans integration can be used as a starting point to develop own DukeScript applications. Just press the Develop button and a new project wizard will be opened as following picture shows:
JavaOne2014 is around the corner and my sessions have been scheduled. I start with a BOF on Monday evening called Virtually Inside-Out! - it is going to be discussion between authors of alternative JVMs. So far we are two: I have mine Bck2Brwsr and Niklas has RoboVM.
Don't you know a developer working on own JVM who will be at JavaOne2014? If so, please tell him to contact me and stop by! I plan to make the BOF a lively chat (how did you implemented lambdas?, how did you implemented defender methods?), but in case we don't have a topic to talk about, I am ready to explain why value classes should not be in JVM and why InvokeDynamic is a completely stupid idea. Anyone from JDK team to defend these proposals?
On Tuesday morning Toni and me will continue with DukeScript tutorial. In case you use Java and want to learn how to code for iOS, Android, JavaFX and browsers, stop by. We will help you create your first application that is written once and displayed anywhere!
I'll finish on Tuesday noon talking about API Design checklist. I'd like to name at least ten things one should check for, but so far I have about two. Don't you have any idea what could be in such checklist? If so, please talkback!
which is shorter and more human readable. However I doubt the V8 virtual machine sees any benefits - I think the final native code remains the same. But at least the debugging of the generated JavaScript code is now easier - there is less Step Over invocations and it mimics more closely the original Java source.
Optimized the ahead-of-time compilation, so now the
http://xelfi.cz/minesweeper/bck2brwsr/
demo starts up instantly. I had to do it, because it was so embarrassing to see TeaVM to boot the same application so quickly: The initial delay is gone, and moreover it downloads necessary libraries in parallel and on background. Now we are ready for next step: share the libraries between different applications.
Can ObfuscatePerLibrary - e.g. each JAR gets compiled ahead-of-time into its own JavaScript file, which can be shared between many applications.
Before Nashorn (the JDK8 JavaScript engine) performing calls between Java and JavaScript was a pain. Especially when it came to debugging. But now, one can completely freely mix Java and JavaScript inside of a single thread and still be able to debug and inspect the slightest details of Java as well as JavaScript stack frames.
The Japanese translation of my book has been in progress for several months. Recently I've been asked by Yoshiki to write a preface.
I wrote one and I tried to express how wonderful experience it had been to participate in the Japanese translation. I believe the Japanese version of my book will be great.
Thanks Yoshiki for your work. Dear (Japanese reading) readers, enjoy!
I've managed to prototype a way to share UI between two rich client platforms. These days it is popular to use HTML, so I did it. However in addition to that I managed to remove all need for JavaScript. Design in HTML and code your application logic in Knockout4Java.
I am pleased to announce there is now a way to develop applications for iOS using your favorite language (I mean Java) and your favorite development IDE (I mean NetBeans).
With the help of Prague's JavaFXiOS team we now have a NetBeans plugin that helps anyone develop JavaFX based Java apps for iOS. Many thanks should also go to RoboVM guys for creating such easy to use Maven plugin.
The profiles support is coming for JDK8. Not only it is coming, it works! In case you are searching for a small Java, give profiles a try. They are easy to start with.
I'm proud to announce DEW - the development environment for web (of course in Java). I am tired of observing JavaScript being on the rise while pretending it is more than just a script language. The real language is Java and it does quite well with HTML. Check DEW here: http://dew.apidesign.org/dew/ and you will not regret!
The more you fiddle with DEW and the more you alter (and save) the samples, the more we will help Java get Bck2Brwsr!
Debugger is a very useful tool. I greatly recommend it to everyone who asks stupid questions on mailing lists and reports vague bugs into bug tracking systems. If your application does not work: use the debugger! Read here to learn how.
