==== Mirror NetBeans Update Center Catalog ====
+
==== [[Apache]] Projects can Distribute [[GPLwithClassPathException]] components! ====
-
Here is a note about my latest practical achievement. I have created an [[netbeans:File:Mirror.xml|ant script]] to clone content of any NetBeans ''catalog.xml(.gz)'' available online. It reads the list of available modules, allows you to choose the ones to mirror (using a regexp on cluster or module names), downloads them (skips the download when an NBM file with same or newer version is already available locally) and generates new ''updates.xml'' file to represent your local repository.
+
Thanks to our [[DirectAction]] - e.g. organizing a [[DirectAction|vote without a common consent]] - it has been decided that as of 2021 Apache projects can distribute [[GPLwithClassPathException]] components in their complementary binaries!
-
Enjoy [[netbeans:File:Mirror.xml|Mirror.xml]] script!

==== [[API]] Quiz at [[Ostrava]] JUG on March 2nd, 2011 ====
+
Including [[GradleWrapper]].properties in each [[Gradle]] project follows the [[PropertyFiles|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!

==== Real [[Hotswap]] is not Only About Classes ====

At the end of May 2020 the GitHub guys announced a [[Malware]] attacking developer machines via [[NetBeans]] [[Ant]] based projects. [[Malware|Read more]]...
-
I received few very good comments after blogging about the ''true'' hotswap for JDK. Thus I need to slightly correct my original opinion. Not only we need ''true'' hotswap, but we need [[Javeleon|real hotswap]]! Dealing with updates of classes is just a first step. We need tools like [[Javeleon]] to integrate well with [[Javeleon|all other aspects]] a framework needs to offer to make the hotswap feel [[Javeleon|real]].

==== Twenty Years: Sun Microsystems Acquires NetBeans ====

==== [[Netbinox]] is Built Around Unmodified [[Equinox]] Now ====
+
PALO ALTO, Calif. - Oct. 20, 1999 - Sun Microsystems, Inc. today announced it [[SunBuysNetBeans|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.
-
Those who follow my work on [[Netbinox]] may be pleased that since Feb 12, 2011, the [[Netbinox]] version 1.16.8 bundles unmodified version of ''org.eclipse.equinox.jar''. The functionality remains unchanged but your legal organization may accept this new setup more happily.

==== Renewing [[TheAPIBook]]'s domain ====
+
My first blog post on medium - [[AOTMadeFaster|Improving performance of GraalVM native images with profile-guided optimizations]] is out. It rounds up my last few months efforts as the '''-Dgraal.PGOInstrument''' option is what [[I]] have been intermitently working on for at least [[FourthGraalAdventures#Collecting_profiles_for_guided_optimizations|last year]].
-
Yesterday I managed to prolong the [[TheAPIBook|apidesign.org]] domain for next three years. I can see there are some followers out there, and anyway I need a place to dump my mind to. Thanks for reading my posts and happy New Year 2011!

Have you ever faced errors during initializaiton of your [[OpenJDK]] virtual machine? Something like:

Don't hesitate and make the switch! [[Apache]] [[NetBeans]] has just switched today!
-
<source lang="bash">

[[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 [[OracleLabs]] [[GraalVM]] [[NativeImage]] turns [[Java]] into a system language!

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.

==== Throw Away Your Bug Tracking System ====

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!

==== The Differences Make the Difference! ====
+
==== The [[IDE]] for [[DevOps]]! ====
-
The flow of questions about the [[Netbinox#The_Differences|difference]] between [[Netbinox]] and Equinox does not seem to run dry. That is why I reorganized the [[Netbinox]] page to also describe the technical [[Netbinox#The_Differences|differences]] between those two OSGi containers.
+
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]]!
-
The primary difference is that [[Netbinox]] is way faster for launching desktop applications than its up stream project. This is the positive difference. However together with this side of the story, one also gets the other one. The behaviour responsible for the speed up is also most likely the one to the deviate from the original's functionality.
+
Read [[DevOps|more]]...
-
The behaviour of [[Netbinox]] is deeply covered by tests, however that still does not guarantee it is completely identical. But be assured compatibility remains the biggest [[Netbinox]] goal. If you want some details, read [[Netbinox#The_Differences|more]]!

In need of compiling Java ahead-of-time? See [https://github.com/JaroslavTulach/incubator-netbeans-html4j/blob/examples/examples/jsonparse/README.md 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]]!
-
An old friend of mine asked me about my experience with [[Mercurial]]. Probably he wants to migrate his team to some good distributed versioning system. As I can't sing I can only recommend that. In case you are in similar situation: Use [[Hg]]!

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.

Let me (with a little bit of delay, as the release happened on Dec 10, 2009) describe the [[netbeans::Fitness68PressRelease|performance improvements]] we delivered as part of NetBeans 6.8. Please also note that we almost managed to provide what we [http://wiki.netbeans.org/wiki/index.php?title=Fitness68PressRelease&diff=32062&oldid=27424 originally promised] half a year ago. That is not bad.

==== [[API]] Design under Attack! ====

Also notice the power of [[Teamwork|working backwards]] methodology. Writing press release before starting the real work (as advocated in [[Teamwork]] chapter of [[TheAPIBook]]) provides almost perfect self perspective mirror. I guess it is time to write press release for NetBeans 6.9!
+
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 [[Bck2Brwsr 0.17|Grenoble]] was so popular that it attracted that much attention!?

The project is also glad that binaries of the new [[Html4Java|HTML/Java]] version 1.2 are now included in forthcoming [[NetBeans]] 8.1 release making it easy to develop [[netbeans:HtmlUIForTemplates|wizards]] as well as components and dialogs in a cross-platform manner (e.g. able to run in [[NetBeans]] platform applications, IDE, [[HTML|Eclipse]] RCP, plugin-less [[Bck2Brwsr|browser]] and thanks to adoption by [[DukeScript]] project also on [[iOS]] and [[Android]]).

==== [[Equinox]] is not an [[OSGi]] Container! ====
+
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 [[Truffle]] [[AST]], it can still provide enough valuable information in the debugger.
-
Give people a finger, they will ask for [[Equinox|whole hand]]! I gave every [[OSGi]] lover [[Netigso]] (based on [[Felix]]) and guess what many said! We don't want [[Felix]], we want [[equinox]]!

==== PF 2009: Get on Board! ====

I have discovered a nice checklist of [[guidelines]] considered good for API design.
-
Dear readers of my book and my blog, I've mentioned in [[The Future|Epilogue]] of [[TheAPIBook]] that I good tools can help anyone do better job. I backed my reasoning by a skiing parallel. Recently I found an old video to explain what I really meant. Thanks for your interest in [[API Design]] and I wish you good tools in 2009 to help you get on the board!

Many systems store their configuration in some form of [[PropertyFiles|property files]]. However a lot of them is not doing that really properly. The results can then be quite painful. Just like when I recently played with [[PropertyFiles|OSGi manifest files]]. Read my [[PropertyFiles|story]] and [[PropertyFiles|feel]] my pain...

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!

==== NetBeans 6.5 Performance Press Release ====

How can one announce to the world that something important happened? Via [http://wiki.netbeans.org/Fitness65PressRelease Press Release], of course! However, one question stays: who can write good press release? Engineers are generally seen as incapable of doing so, however as argued in Chapter 14, [[Paradoxes of API Design]], there is a way to help them: Force them to write [http://wiki.netbeans.org/Fitness65PressRelease documentation or press release] before they start to code!

When I was defining the quest of [[APIFest08:Task3]] I needed to set a deadline. However as the [[APIFest08]] is not competition for millions of bucks, just for [[TheAPIBook]], I did not feel I need to be exact enough and I defined the deadline as ''Fri, Oct 10, 2008, morning of CET''. This is the reaction that I got from one of the participants:

I really like the precision you use in specifying the deadlines!

I will choose to interpret "Fri, Oct 10, 2008, morning of CET" as

However I could not do that, because the picture is of really low quality. That is why I needed a new re-take. We already [[HtmlForFood|have some]], but still, I'd like us to start sharing! As sharing of pictures is sometimes easier than sharing of API Design ideas, please participate in a photo contest! Get a chance to

Midlife Crisis of an API Designer

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 good APIDesign 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...

Run JUnit in Your (Java Plugin-less) Browser!

Bck2Brwsr 0.19 comes with many little improvements and one new feature: it can execute JUnit in the browser!

  • Better support for Annotation - so good that bck2brwsr can now execute JUnit tests
  • Support for all classes from java.util.concurrent package, so JUnit runs without problems
  • Switching to version 2.1.0 for RetroLambda
  • More robust generated JavaScript file - doesn't override already defined classes
  • Uses version 1.3 of Html4Java API.
  • Record name of an OSGi bundle to be used when Maven coordinates are missing like in JUnit case
  • Don't convert Date objects to current time millis
  • Use boolean.valueOf() to simplify mixing of boxed and unboxed booleans
  • Perform more conversions before returning Java value to JavaScript from a Java callback
  • Launcher.createBrowser can specify its own page
  • Make sure class cast exception contains the same message as produced by JDK
  • Convert undefined value read from arrays into null
  • Convert content of array properly before entering JavaScript
  • Turning the bck2brwsr VM into an OSGi bundle
  • Introducing vmtest.precompiled=<regexp> property to verify that bck2brwsr generated resources are really used
  • Don't include VM in VMTest initialization, let it be loaded on demand
  • System.exit terminates associated launcher
  • eval(JavaScriptResource) as string to prevent double obfuscation
  • Don't report warnings when generating minified version of bck2brwsr libraries

Get the bits from the Maven central repository!

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 API 1.3 is Released!

I'd like to announce that the new version of HTML/Java API - e.g. 1.3 is ready for usage. The javadoc is at http://bits.netbeans.org/html+java/1.3/ - and the bits has been uploaded to Maven central.

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.

API Design under Attack!

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

Snowcamp in Grenoble gave Bck2Brwsr 10x Speed Up!

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 Java VM 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.

Enjoy the Bck2Brwsr 0.17's speed!

MineSweeper 3.0 for Your iOS Device. The Christmas Thriller Edition!

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...

Here are the changes against standard MineSweeper source code to make the application releasable on the AppStore this time: https://github.com/jtulach/minesweeper/compare/9fc7970496a...0d6984c73

Enjoy version 3.0 of Fair MineSweeper on AppStore. Visit https://itunes.apple.com/us/app/fair-minesweeper/id903688146 to play fair!

Can Java Speed Ruby up? Yes, ten times!

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.

Watch this video to see how can Java and its virtual machine help those other poor and slow languages!

HTML/Java version 1.2.1 has been Released!

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!

Design with Truffle. Get Debugger for Free!

Truffle - a modern way to write AST interpreters - gives you not only speed, but also debugger for free:

Image:TruffleDebugger.png

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 Truffle AST, 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!

Bck2Brwsr 0.12 has been released. What is new?

Libraries can be pre-compiled and published as Maven artefacts (see Bck2BrwsrLibraries how to). The Knockout4Java Maven archetype has been modified to use the precompiled version of Bck2Brwsr rt. jar emulation library and HTML/Java APIs:

$ mvn archetype:generate \
  -DarchetypeGroupId=org.apidesign.html \
  -DarchetypeArtifactId=knockout4j-archetype \
  -DarchetypeVersion=1.1.2 \
  -Dbck2brwsr=true
# answer few questions...
$ cd nameofyourproject
# run on desktop
$ mvn process-classes exec:java
# run in a browser
$ mvn -Pbck2brwsr clean package bck2brwsr:show

Supporting Bck2BrwsrBlobURLs so one can display images available as in JAR resources.

Happy Year 2015 and please help me get Java Bck2Brwsr!

JavaOne2014: Need Speakers for My Session!

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!

Bck2Brwsr Revision 0.9 is Released!

Version 0.9 eliminates useless stack assignments. Instead of doing

var stI0 = lcI0;
var stI1 = lcI1;
var stI0 = stI0 + stI1;
return stI0;

the now generated code is

return lcI0 + lcI1;

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.

Debug Mixed Java/JavaScript 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.
