I was reading eclipse collections benchmark doc and realized that its little bit old and it was using jdk 11, in my local I have jdk 14 I wanted to run in my local and see the result. You can find eclipse collections here Below from my local D:\tmp\benchmark-eclipse-collections>java -jar target/benchmarks.jar IntegerListFilter -rf json WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.openjdk.jmh.util.Utils (file:/D:/tmp/benchmark-eclipse-collections/target/benchmarks.jar) to field java.io.PrintStream.charOut WARNING: Please consider reporting this to the maintainers of org.openjdk.jmh.util.Utils WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release #

I was trying to use freemarker with quarkus and vertx. I start getting this error Could not find MessageBodyWriter for response object of type: io.vertx.reactivex.core.buffer.Buffer of media type: text/html;charset=UTF-8 And code look like below. I was trying to use reactive approach. @GET @Produces(MediaType.TEXT_HTML) public Uni<Object> doSomethingAsync() throws Exception { io.vertx.core.Vertx params = vertx.getDelegate(); io.vertx.reactivex.core.Vertx args = new io.vertx.reactivex.core.Vertx(params); FreeMarkerTemplateEngine engine = FreeMarkerTemplateEngine.create(args); List<ExampleObject> exs = new ArrayList<>(); for (int i = 0; i < 10; i++) { exs.add(new ExampleObject("name:" + i, "dev:" + i)); } HashMap data = new HashMap<>(); data.put("title", "Vert.x Web"); data.put("exampleObject", new ExampleObject("name", "dev")); data.put("systems", exs); Single<Buffer> rxRender = engine.rxRender(data, "/templates/index.htm"); Buffer page = null; try { page = rxRender.toFuture().get(); } catch (Exception ex) { ex.printStackTrace(); // e.printStacktrace(); } return Uni.createFrom().item(page); } I check and could not find a proper solution here is how I solved it. ...

While developing a small android application. I was thinking to use IntentService which is kind of a background worker for android platform. Then I found the need code and documentation and implemented yesterday. and code is compiling so today I wanted to see it in a real phone and started Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.mascix.fitinsta/com.mascix.fitinsta.ServiceLayer}; have you declared this activity in your AndroidManifest.xml? From this exception I understand that I am having a problem in androidmanifest.xml and since morning I was trying to fix it. And the result is it was code problem :) ...

I have been using whois for a long time(around 10 years). and if you are sending this whois queries from same ip and higher then expected. you will start seeing ripe.net access denied results. one solution is restart your adsl modem. or start using another ip. and my solution is TOR :) sudo apt install tor torsocks you will need to configure torify check https://www.linux.com/blog/beginners-guide-tor-ubuntu torify whois 25.166.194.172 and I did not wanted to run in my server. therefore amazon free instance and a micro service https://github.com/ozkanpakdil/CommandRunner did the trick. ...
