When does #Iceberg beat #Parquet+projection on #AWSGlue, and when doesn't ?

An end-to-end #ETL PoC on #AWS to find out: producer, #Kinesis, two #Firehose paths, two #Glue jobs, #Athena.

🔮 Spoiler: how the data is read is the key to the choice.

In the article: every choice with its why, plus a few gems from some Glue experience 😄

Last month I won a #CommunityBuilder premium swag thanks to the #MachineLearning 4x4 initiative 🎉

I shared my repo about real-time Video-to-Text transcription using #AmazonTranscribe Streaming, FastAPI, and ffmpeg: https://github.com/bilardi/video-to-text/?tab=readme-ov-file#video-to-text

And here’s the related article where I talked about the architectural choices and the story behind the project: https://dev.to/bilardi/realtime-transcription-choices-and-stories-for-pycon-it-4ehd

#CodeQuality of the lazy developer 🛠️

Updating an educational #Python repo, I looked into what to automate for code quality.

🔮 Spoiler: I landed on uv, ruff, pyright and pre-commit.

In the article: the picks, why, and the make patch that broke on the first try 😄

#RealtimeTranscription for #PyConIT 🎙️

Whisper hallucinated on real conference audio: a problem I skipped for time: everything else to build.

🔮 Spoiler: #AmazonTranscribe doesn't generate text, it decodes it.

In the article: the choices I made, and the stories you only find when plugging things in (Linux audio is a zoo) 😄

I wrote my first article in the #DiaryOfALazyDeveloper series 🚀

I needed to expose a Docker Compose app for a workshop: HTTPS, custom domain, backups, teardown with one command. ECS was overkill, manual setup was fragile.

🔮 Spoiler: one terraform apply does it all 🏗️

In the article I describe every choice and why, driven by experience and the laziness of doing things by hand 😄

Questa settimana ho fatto la-due-giorni-a-Bologna 🚀🚀

Intensa di #talk ispiranti, #gadget bellissimi … e le persone hanno reso tutto davvero indimenticabile. ✨

Conosco i retroscena dell’organizzazione e i ragazzi del @grusp hanno resto tutto perfetto, leggero e spensierato .. sebbene non fosse per nulla facile 💪

E’ sempre un piacere essere accettati come #speaker ai loro eventi ❤️

Alla prossima !

#DataAnalysis #Dask #Kubernetes #ParallelComputing #Scalability #AWS #DevSecOpsDay #ContainerDay

Siamo pronti per gli eventi del @grusp ?

Parlerò al #ContainerDay25 tra #SoftwareArchitect, #CloudEngineer e #PlatformSpecialist .. un po' #outsider ?

Tutt’altro: i dati oggi viaggiano in produzione, dentro cluster orchestrati e hanno bisogno di essere scalati, gestiti, monitorati proprio come il resto del software !

📍 Ci vediamo a #Bologna !

Ma lo conoscete l’#EndSummerCamp ⁉️

La scorsa settimana sono andata all’#ESC21, un evento #hacking e #making in #FOSS style dove ho seguito alcuni #talk interessantissimi spiegati in modo semplice anche per i non addetti come me ‼️

Se ve lo siete perso, niente paura: i ragazzi dell’#ESC2k25 hanno preparato una #playlist su #youtube !
