Last week, Greg and I had the pleasure of sitting down with Andres Almiray from Oracle to discuss this week's release of Java 22. I was hoping to get this episode out sooner but ended up fighting it out with a fever.

I like that it's easily expandable and not too different from other languages that use r"Raw String here".

Episode 175 - 18 And Life
Until last week, I was going to open the show saying it's been a long time since we last recorded, but we slipped in an interview with the guys from plz.review - so that's not exactly true anymore. It has, however, still been a while since we've had a normal, full session of discussion and argument.
Delayed: The publishing/editing of this episode was unfortunately delayed due to me finally catching Covid.
plz.review Updates Github "integration" is available, we even had GerritForge - Home page listed in the show notes, as part of GerritForge there's GerritHub for online hosted Gerrit+GitHub integration which uses Gerrit's replication plugin, and a Github integration for authentication/authorization.

Reddit Post: Improving on the GitHub code review comment experience : programming Blog Post: Bit Complete Blog: Improving on the GitHub code review comment experience | Bit Complete Inc. YouTube Introduction Video: Introduction to plz.review - YouTube Website: plz.review Guests: Dylan Trotter, Matt Schweitz
It's been a while since recording, and as it happens, just before organizing the next episode, full of “discussion” on the recent Java 18, and forth-coming Java 19 release, I came across an r/programming post from Dylan Trotter from Bit Complete about their new stacked code review tool for Github.
After reading the post, linked blog post, and introductory YouTube video, I reached out to discuss the product, the problems with Github's default PR model, and code review in general.
Contents 00:00:03.754 Introduction 00:01:07.236 Bit Complete History 00:02:24.492 What Makes A Good Code Review? 00:12:32.219 DORA (not the Explorer) 00:14:38.308 Bisecting Squashed Commits 00:18:51.617 The plz.review Solution 00:19:08.934 plz.review Stacks - Grouping PRs Together 00:21:36.969 plz.review Revisions: Force push solutions 00:25:37.590 plz.review Migration - Moving from Gerrit? 00:29:34.371 Gerrit and Github Integration 00:32:23.516 Compromising your workflow to fit Github PRs 00:39:41.700 Code Review as Mentorship / Education 00:41:26.759 Github: Social Coding brought code-review to mainstream 00:45:52.124 Long Lived Support Branches 00:50:03.479 How to signup for plx.review OverviewBefore we get into plz specifics - I assume both Dylan and Matt have some interesting takes on what makes a good review:
What makes a good review? What constitutes good review "hygiene"? Mark: IMHO A review/commit/PR should ideally do one thing. What the "thing" may be intangible, but ideally: If you're going to reformat code, keep it in a commit separate from business logic changes. If you're updating dependencies, keep them separate from business logic changes, however do include code changes to ensure the build continues to build and pass tests. If a dependency update introduces breaking API changes, keep that dependency change along with the implementation for it. Laurence Tratt: Programming Style Influences Practical guide to DORA metrics | Swarmia DevOps Research and Assessment - The four DORA metrics are: Deployment frequency: How often a software team pushes changes to production Change lead time: The time it takes to get committed code to run in production Change failure rate: The share of incidents, rollbacks, and failures out of all deployments Time to restore service: The time it takes to restore service in production after an incident The first three metrics I can see being highly impacted by small changes, automated testing and CI integration. These all intersect with code reviews – having visibility that a proposed change actually compiles, passes tests, and doesn't introduce any new security issues before a co-worker even looks at the change speeds up the process. Stacked code reviews promote keeping pull requests small | Swarmia changes (with small being a subjective size), We've spoken on code formatters before on the show, keeping consistency for reviews is a good thing regardless of being automated or not. plz.reviewThe project/platform appears to solve several issues we're facing with Gerrit, and our adoption of Azure Devops:
Azure Devops is unable to pull from patch-sets, due to the private rev nature of Gerrit Writing custom Azure function(s) to listen to Gerrit events and manually trigger a Devops build is viable, but not ideal.The prospect of abandoning Gerrit and switching to Githubs force push and squash approach makes me cry,
Coming from the Gerrit Code Review Tool it's great to find a stacked review tool for Github, having people getting in the habit of force pushing to remotes just promotes bad hygiene IMHO. Looking at the available docs, several interesting things come to mind: Comparison: Gerrit and GerritForge - Home page - which I've used in the past for some open source work (GitHub - repaint-io/maven-tiles: Injecting maven configurations by composition rather than inheritance originally used GerritForge). Gerrit keeps all patch-sets - and lets you compare diffs between patch-sets, is that also mirrored within plz.review? I guess Github would only track to latest/amended PR. Looks like the plz command line generates its own form of Change-Id footer: plz-review-url which tracks revisions of a change linking to https://plz.review/review/NNNN - which doesn't appear to be name-spaced in any way (company or repo). Gerrit's UI is getting better, but still leaves a lot to be desired – I still wish improvements to commenting/UX were more of a focus. plz.review's UI also seems simple in design (not necessarily a bad thing), UI/UX design is hard in general, the requirements of a stack version control also seem to make it a tricky balance between fully featured, and clean….` Gerrit Migration – Given git patch-sets/comments are all in git refs, is there a migration strategy to expose them into plz.review/github? Is there a potential migration strategy? plz.review feels early in the development stage. Such things may not have been considered, or deemed out-of-scope for the system. Comparison: Graphite — Modern code review for fast-moving teams - Open Source CLI/web dashboard stacked review tool based on Git, designed to work with Github. - Graphite beta demo [December 2021][V2] - YouTube - Stacked diffs for fast-moving code review - The Changelog: Software Development, Open Source (Change Log Podcast Interview). Automated bot responses - with CI/test results often being published back into Github PR's as validations for viable PR merges, do these get reflected in the plz UI, or even -2 rejections? Dealing with commits outside of plz.review - such as automated release commits that push direct to GH / potential conflict resolution (having access to Gerrit's local git repo has often been a godsend). What's the business model for plz - per repo charge? per organisation? per user? -

Once again it's been a long time coming between episodes, Auckland's recent extended Covid lock down and Mark's unscheduled and temporary relocation meant we missed out on discussion the release of Java 17 - and with Java 18 not all that far away, we thought it was about time to once again get our record on.
Andres Almiray once again joins us to talk releases, and specifically the JReleaser tool.

What’s this? Another Illegal Argument episode already? And so close to the last one - it seems the shift to working from home and remote recording has already showed a payoff.
During the last episode, I’d had it in my mind to discuss the need to improve our documentation, and general communication skills that developers, and development teams often overlook. More so now that many organisations are moving into distributed, remote teams - many of which may never return to normal “office life”.
With this in mind, I thought I’d make use of our new remote recording facilities and bring on both Tim McNamara (Vice-President of NZOSS, Canonical Guy, Author of Rust In Action) and Josh Addison (Technical Writer at MYOB, Game Developer, Conspiracy Podcaster) to lend their voices to our argument.
On this episode we cover (or planned, as always - things got sidetracked):
Java News JEP 384: Records (Second Preview) Why #Java record getters have no 'get' prefix? Call for Discussion: New Project: Leyden (static compilation for Java - the return of GCJ?) Technical Writing Why Writing Software Design Documents Matters Things Markdown got Wrong Writing Test Plans Architecture Design Records How to write better tickets/commit messages/emails etc. etc. Tooling? Asciidoc ProWritingAid, Grammarly Dropbox Paper Vale - cross platform command line style checker Question-led docs, e.g. cookbook type Doctests are better than you think Knowing your audience - differences between "documentation" and "book writing" Rust In Action WriteTheDocs SlackFull links to everything discussed and planned to discuss are found over on my raindrop bookmarks.

Welcome to the “Locked Down Dependencies” remote recorded using Squadcast.fm whilst both Greg and I are stuck in a national COVID-19 lockdown.
Full links to topics discussed can be found in the shared bookmark folder on Raindrop, but during tonights episode we discuss:
How lockdown is affecting us The Release of Java 14 Beyond Java 8 and the Java Module System - a discussion over two recent streams/videos from Nicolai Parlog on new features in Java 9-14, and issues with the module system. Maven Dependency Pop Quiz Managing Technical Debt at scale, and designing large scale systems. Improving communication among teams in a work-from-home/remote-work world. Guides to writing technical documentation, test plans, better emails and bug reports. -
Welcome to the first episode of 2020 - recorded just before all of Coronavirus Mania and then promptly the editing and publishing got unfortunately thrown to the sidelines for a week.
