Konferencije JavaCro u 2022. / JavaCro Conferences in 2022

Ove godine pripremili smo zanimljive novosti vezano uz održavanje konferencije JavaCro!

U tradiciji dugoj već 10 godina u kojima se konferencija JavaCro održavala na različitim lokacijama u Hrvatskoj, najčešće na moru, ove godine se ponovno vraćamo na mjesto gdje je JavaCro priča i započela – u Tuhelj. Oni koji su od samih početaka s nama sjetit će se netom dovršenog hotela Well te niza zanimljivih predavanja od poznatih predavača kao što su Java Championi Gavin King (Hibernate), Juergen Hoeller (Spring, VMware), Angelika Langer (nezavisna konzultantica), Geertjan Wielenga (Oracle, sada Azul) i Matjaž B. Jurič (University of Ljubljana).

Mnogi sudionici su nam rekli kako je vremenski razmak od cijele jedne godine između dvije konferencije često predug period u kojem tehnološki napredak ne posustaje, već naprotiv, u međuvremenu se pojavi veći broj novosti koje se ne stignu predstaviti u kraće vrijeme nakon objave ili se stavljaju “na čekanje” do sljedeće konferencije. Osim toga, jedna godišnja konferencija često je opterećena s mnogo predavanja u različitim dvoranama u isto vrijeme pa neka kvalitetna predavanja ne dođu do izražaja ili su stavljena na listu čekanja. A sad čak i sama Java ima dva izdanja godišnje! Stoga je naša ideja da godišnje održimo dvije konferencije JavaCro, jednu u proljeće, a drugu u jesen, kako bi mogli dobiti bržu i primjereniju razmjenu informaciju te pravovremeni prijenos novosti, a na taj način bi se moglo prihvatiti i veći broj predavanja. Osim toga, naša želja je posvetiti više vremena na konferenciji najboljim rješenjima iz prakse tzv. “Best practices & success stories” i razmjeni iskustava.

Konferencije JavaCro poznate su ne samo po izvrsnim predavanjima i predavačima, nego i po kvalitetnom i korisnom druženju u manje formalnim trenucima i u zabavnoj atmosferi, u kojoj se često lakše ostvaruju kontakti među sudionicima, kao i razmjena znanja i iskustava, što će ostati naša praksa i u budućnosti. Vrlo često su baš ti razgovori i izravni kontakt svih sudionika i predavača, rezultirali bržem i boljem rješavanju problema i tehnološkoj optimizaciji rješenja, ali i uspostavi vrlo korisnih suradnji i partnerstva.

Stoga Vam u 2022. godini predstavljamo čak dva izdanja konferencije JavaCro, a prva jubilarna konferencija JavaCro’22 Spring održat će se od 15. do 17. svibnja u Tuhelju.

Ovu obljetnicu namjeravamo zajedno proslaviti i radujemo se što ćemo se vidjeti na JavaCro’22!

This year, we have prepared some interesting news related to the JavaCro conference!

In the last 10 years, the JavaCro conferences were held in various locations in Croatia, most often at the seaside; however, this year we return to the place where the JavaCro story began – to Tuhelj. Those who have been with us from the very beginning will remember the newly completed Well Hotel and a number of interesting sessions from famous speakers, including Java Champions Gavin King (Hibernate), Juergen Hoeller (Spring, VMware), Angelika Langer (independent consultant), Geertjan Wielenga (Oracle, now Azul) and Matjaž B. Jurič (University of Ljubljana).

Many participants told us that the one-year gap between the two conferences is often a too long period in which technological progress does not slow down, but on the contrary, in the meantime a larger number of innovations appear that cannot be presented in a shorter time right after the announcement or are put “on hold” until the next conference. Furthermore, one annual conference is often burdened with many lectures in different tracks at the same time, so some quality lectures do not come to the fore or are put on a waiting list. And now even Java itself has two releases a year! Therefore, our idea is to hold two JavaCro conferences a year, one in the spring and the other in the fall, to get a faster and more appropriate exchange of information and timely sharing of news and accept more lectures. Moreover, our desire is to dedicate more time at the conference to the best practices, success stories, and exchange of experiences.

JavaCro conferences are known not only for excellent sessions and speakers but also for quality and productive socializing in less formal moments and a fun atmosphere when it is often easier to make contacts between participants and exchange knowledge and experiences, which will remain our practice in the future. Most often, these conversations and direct contact of all participants and speakers resulted in faster and better problem solving and technical optimization of solutions as well as the establishment of beneficial collaborations and partnerships.

Therefore, in 2022, we present two editions of the JavaCro conference, and the first 10th JavaCro’22 Spring conference will be held May 15 – 17 in Tuhelj.

We would like to celebrate this anniversary together and we are looking forward to seeing you at JavaCro’22!

Konferencija Javantura / Javantura Conference

Dragi članovi HUJAK-a i simpatizeri Jave i srodnih tehnologija,

željeli bismo vas ovim putem obavijestiti da s obzirom na trenutna ograničenja i preporuke vezane uz pandemiju COVID-19 i informacije koje trenutno imamo (siječanj 2022.), nažalost nećemo moći održati konferenciju Javantura u prvom dijelu 2022. godine na način kako smo namjeravali!

Stoga, kada se uvjeti vezani uz održavanje konferencija promijene, ponovno ćemo razmotriti održavanje konferencije Javantura i obavijestiti vas o tome.

Zahvaljujemo na razumijevanju,

Časopis Mreža – nova Java 10 te konferencije Javantura v5 i JavaCro’18

U posljednjem broju časopisu Mreža (05/2018) koji se već pojavljuje na kioscima polovicom travnja, osim niza drugih zanimljivih članaka, možete pročitati i članak predstavnika HUJAK-a, Branka Mihaljevića i Aleksandra Radovana, o posljednjem izdanju platforme Java 10 koja je javno objavljena 20. ožujka 2018., kao i kraći izvještaj s konferencije Javantura v5 te poziv na nadolazeću konferenciju JavaCro’18.

Java-logo.jpg

Autori su na pokušali prikazati najvažnije novosti vezane uz novu Javu 10 (uključivo Local Variable Type Inference, unaprjeđenje garbage collectora i Parallel Full GC for G1, zaustavljanje pojedinačnih threadova, podršku za alternativne memorije, Unicode ekstenzije, Graal, nove krovne certifikate i dosta drugog “proljetnjog čišćenja”). Također, prikazan je novi sustav objava i označavanja verzija Jave i ukratko objašnjen sustav podrške (dugoročne i kratkoročne). Na kraju je naglašeno što je važno u ovom izdanju, što se očekuje u narednoj verziji te treba li prijeći na novu Javu čim prije. U nastavku donosimo nekoliko fotografija članka i dijelove teksta, a za ostalo ćete morati nabaviti svibanjsku Mrežu. 🙂

Proljetna Java 10

Globalno najpopularniji programski jezik i razvojna platforma objavila je novu inačicu samo šest mjeseci nakon prethodne

Točno šest mjeseci nakon izdanja Jave 9 i dan prije službenog početka proljeća stigla nam je nova Java, odnosno prateći JDK (Java Development Kit) kao referentna implementacija za Java Platform, Standard Edition 10. Testna verzija bila je spremna još u prosincu prošle godine, a verzija Release Candidate objavljena je u veljači, tako da nije bilo kašnjenja službene objave nove Jave 10 u statusu opće dostupnosti (General Availability). Ako ste prošle godine pratili zbivanja vezana uz najavu ubrzanja objava novih izdanja Jave, ovo i nije neko iznenađenje. Primijetit ćete da je ovo izdanje sadržajno dosta manje od prethodnog te, iako ima dosta novosti, sigurno ih nema ni upola koliko prethodne godine. Da se podsjetimo, na prethodnu verziju Jave 9 čekalo se čak tri godine, a donijela je više od 150 novih značajki. Najvažnije značajke bile su novi sustav modularnosti i mogućnosti skaliranja aplikacija od najmanjih do najvećih, unaprijeđena sigurnost, poboljšano upravljanje učinkovitošću te posljedično jednostavniji razvoj aplikacija najpopularnije razvojne platforme na svijetu, koja se izvodi na čak tri milijarde različitih računala i na kojoj aplikacije razvija desetak milijuna developera.

Ako želite saznati više, predlažemo da posjetite barem neke od developerskih konferencija i meetupa s temama razvoja u Javi, od kojih su neke i u Hrvatskoj. Na kraju, ako već radite s Javom 9, onda je nova “desetka” očekivana nadogradnja. Ako tek razmišljate o prijelazu s Jave 8 i potencijalno imate vremena pričekati jesensku Javu 11, možda bi ipak bilo bolje da pokušate vidjeti novitete iz Jave 10 što prije, jer bi “kvantni skok” s verzije 8 na 11 mogao biti prilično velik zalogaj.

Konferencija Javantura v5

Jedna obična subota – 26 predavanja, 300 sudionika i HUJAK

Već tradicionalno, sredinom veljače u Zagrebu održava se najveća jednodnevna developerska konferencija Java zajednice u ovom dijelu Europe, odnosno simpatizera tog programskog jezika i pratećih platformi te srodnih tehnologija. Konferencija Javantura, narasla iz nekadašnjih meetup druženja, nametnula se kao nova obavezna destinacija za developere željne razmjene iskustava, novih ideja i saznanja. Iako volonterski organizirana od grupe entuzijasta okupljenih u neprofitnoj udruzi HUJAK, već petu godinu uspijeva u neradnu subotu okupiti više od tri stotine sudionika, koji su na ovogodišnjoj Javanturi v5 imali prilike slušati čak 26 zanimljivih predavanja poznatih svjetskih i domaćih stručnjaka.

Keynote konferencije bio je Nicolas Fränkel, koji je odmah nakon tradicionalnog obraćanja predstavnika HUJAK-a, predstavio nove sigurnosne značajke nad JVM-om, a nakon toga slijedio je niz zanimljivih tema iz različitih područja u tri dvorane. U prvoj dvorani pričalo se tako o monitoringu JVM-a, generatoru aplikacija JHipster, “fantastičnim” ugovorima u Javi, alatu JShell, sustavu Kubernetes, Vaadinovim web komponentama, mikro-servisima i općenito o OOP-u. U drugoj dvorani predstavljene se mogućnosti umjetne inteligencije IBM Watsona, sustav za razvojna okruženja Vagrant, reaktivni scheduleri, nepromjenjive kolekcije, iskustva agilnog razvoja i Scruma te automatizacije poslova. A u trećoj dvorani predstavljen je radni okvir Axon, iskustva s HTTP/2 i novim pretpostavljenim “skupljačem smeća” G1 u Javi 9, alat Java Mission Control, platforma za barkodove, kao i iskustva s drugim srodnim jezicima, kao što su Groovy i popularni Kotlin. Prezentacije i snimke svih predavanja bit će uskoro javno dostupne na stranicama konferencije, a ovim putem organizatori se još jednom zahvaljuju svim sponzorima konferencije: King ICT, ecx.io, netconomy, SV group, Asseco SEE i RIT Croatia, kao svima drugima koji su nam pomogli: HrOUG, Oracle, Mreža, Netokracija, Hrvatski Telekom, CARNet, Entrio i mnogi drugi. HUJAK-ovci se, zajedno s kolegama iz HrOUG-a, već pripremaju za sedmu međunarodnu Java konferenciju JavaCro’18, koja će se od 7. do 9. svibnja održati na Crvenom otoku pored Rovinja.
