The document discusses 'lightning talks,' brief presentations lasting five to ten minutes that focus on clear communication of ideas, enhancing audience engagement. It provides tips for using IntelliJ effectively, such as utilizing shortcuts, managing tabs, and using UML tools like PlantUML. Additionally, it covers Git management techniques, querying server logs, and highlights various useful online development tools and resources.
Tips and Tricks lightning talk @ rego.act
- 2. What is a ‘Lightning Talk’? Lightning talks are designed to be short presentations between five and ten minutes… …to be able to share their ideas and concepts to people who have experience in the specific field… …requires the speaker to make his or her point clearly and rid the presentation of non-critical information… This causes the audience to be more attentive to the speaker and gain a broader array of knowledge from the presentations given… - Wikipedia
- 3. Getting the most out of IntelliJ • Use Alt-Enter to fix things - don’t distract yourself • ‘annotate’ option for viewing git history - useful to find out what commits a file changed in* • Turn off tabs - they slow you down. Use Ctrl-E (recent opened), Ctrl-Shift-E (recent edits)* • Bookmarking is better than tabs* • @formatter for preserving formatting - everyone loves that one… not!* • Heaps of other tips: (See Hadi Hariri - Developer Advocacy Lead @ Jetbrains): https://blog.jetbrains.com/idea/2015/10/intellij-idea-tips-and-tricks/*
- 4. U and Me (should) Love this • UML tools abound… some better ones are proprietary (e.g. Enterprise Architect (Win/Linux) or x-platform like StarUML. Problem: $ Pay-walled/licence costs. • Many require GUI plugins or standalone tooling. • PlantUML is a nifty tool for whipping up diagrams quickly. • Intuitive and rich DSL/markup. • Uses GraphViz (graphviz.org) to render the markup*
- 5. Don’t get aggravated. Get aggregated with aggregator POMs • Group related modules together to conveniently do something with them e.g. build/package an app. • Useful for single-click clean and installs in IJ. • Candidates: standalone apps (web), iConnect WS app. • Example: Front End public web app: rego-wicket-soa, regosoa- common, rego-web-common. Back-end (rego.ear): rego-ear, regosoa-common, rego-service-jiver, rego-common. • Could (should!?) be versioned in AD4B. • Although not included in the parent POM so only built ad-hoc as needed like during development via IJ.
- 6. Git: Interactive Rebasing • Changes not public? • Commit history is messy / not descriptive enough? • Want to do something about it? A: Use git rebase -i • Actions on commits: Combine (squash), remove, edit msg, etc.. Example - 3 text files - not happy with commit msgs… Full Demo
- 7. Server logs • Served over http (Apache Http Server) • Often large 10’s of Mb so slow to view in browser. • Pull for offline use. UAT example: wget --user=uat --password=rego.uat http://regotestapp01.dev.act.gov.au/restricted/logs/purple/rego-debug.log
- 8. Progress reporting • TFS queries - recent example: Bugs In Last 5 days
- 9. Useful online tools • devdocs.io - doco tool with typeahead for heaps of langs/tools/ DSLs. • Stack overflow documentation (Beta)* • Velocity/Zeal documentation browsers* • JSFiddle (html/js/css) - share these around nay collaborate. • Groovy console for quickly checking something e.g. SimpleDateFormat or java.time api experimentation.
- 10. Misc tools • One editor to rule them all - Atom or Visual Studio Code - syntax for HEAPS of langs, markups, DSLs, etc.. • Ditto - clipboard manager - very useful for repetitive copy and paste during testing.
- 11. this::conclude • Slides are on wiki - under TBA! • Suggest topics for next lightning talk: FindBugs, Logging tools/viewers, documentation browsers, more tips/tricks
