@brunoborges Fun fact, many unit tests are keeping lots of unnecessary code alive, because removing it causes a red bar and nobody questions the test.

Fun...

I'm finding a lot of dead code just by asking Copilot to increase test coverage (JaCoCo) to 100%.

@manicode A hacker once typed with great flair. Expecting the system to share. But the AI stood tall, ignored every call, And then he left filled with despair.

A week in Crete with barely any Wi-Fi made me miss the days when phones were our music players. So I built one — a reactive MP3 player in #Java using #Quarkus + Mutiny, complete with metadata extraction. Streaming reimagined, the Java way. 🎧 Read here: buff.ly/C1MVsKa

@RafaDelNero @GeertjanW @AzulSystems Nice! Any pic of the completed build? That was fun to create, we just ordered a bunch more.

Thank you so much @GeertjanW / @AzulSystems for the Duke Lego! I will have fun building it! I just didn’t find the instructions to build Duke. Where can I find it?

@CTOAdvisor Excellent, this is probably the clearest tech article I've read in months.

@frankgreco @brunoborges Ha yeah that’s a fair rebuttal actually.

@costlow @brunoborges You haven't been a commodity trader I see... :)

On the bright side, we just got yet another proof that unregulated crypto is *not* the future.

@frankgreco @brunoborges disagree, there is a market for pork bellies. People use them, they don't FOMO them.

@brunoborges Crypto became popular during the pandemic because neither equities nor fixed income generated alpha. Crypto was a prayer for many investors. It's merely a commodity no different than pork bellies.

@AriT93 First came the software bugs, then came the bed bugs.

Anyone cheering the twitter dormitories/camps/ghettos is an absolute fucking moron and horrible person. If Twitter is still running in 6 months every tech co will start trying to do the same. There will be Ted talks and blogs and shitty biz speak books…

@pwntester Yes

Not that Im aware of. We wrote a tool that reports the attack surface (sources) and hotspots (sinks) for a given CodeQL database. If thats something you would find useful, I can polish it a bit a publish it

@myfear Most of my alerts now are spam bots. I'm not wildly active but now Twitter is just annoying.

Yeah. I can absolutely see the amazing spike in new users for Twitter. All highly engaged and great content producers. 😆👏 awesome job chief twit. #noxp

@carldea Oof that’s a bad move. Why wait a decade of ignoring it to turn it on only after its deprecated.

Solr 9.0 - Release notes. Solr now runs with the Java security manager enabled by default. Hadoop users may need to disable this. Does anyone know other popular frameworks still using the security manager?

@madplatt You over on Mastodon yet?

Buckle up people. It’s about to get bumpy
