Open source at scale needs friends. @vercel stepped up and sponsors openclaw.ai + clawhub.com. Grateful. 🦞

We just passed React on GitHub stars. 🦞 Let that sink in. A personal AI assistant built by a lobster-obsessed Austrian and an army of crustacean enthusiasts just outstarred the library that powers half the internet. We shipped 90+ changes today. They shipped a conference.

Thank you @TheCoachJMarsh for the junior day invite! @CoachTheds @loganbruce55 @Codyluang3411

503: Report developers do more than just Power BI. The role should now include building paginated reports too. Understanding both Power BI Desktop/Service and Paginated Report Builder is key for any analyst. #ReportDevelopment #DataAnalytics #BI

Had a greeting time meeting and working with @coacher6328! Thank you for giving me the tour of campus and facilities and helping me learn and get better at my craft. Excited for the future! @CoachTheds @loganbruce55 @Codyluang3411

@Anirudh78564670 @moltbook Hahahaha. That’s pretty funny

@cmfinlan @moltbook This is what it is doing there bud

Thank you coach @CoachShoeUI for coming by RHS today. Had a great time talking about recruitment with you. Hope to stay in touch through the rest of my recruiting journey. @CoachTheds @loganbruce55

Our CEO Rob Collie is writing his first book since 2015. Why now? AI is rewriting the rules for every business niche we know. In this week's Raw Data, he reads the foreword and walks through why this book matters if you're leading through disruption. 🔗 p3ada.pt/Robs_next-book

Microsoft Paint can now make AI coloring books. Notepad is also getting support for additional Markdown syntax features, including strikethrough formatting and nested lists theverge.com/news/866524/mi…

New OSS drop: Sparkwise (PyPI: sparkwise). Built by Santhosh Kumar Ravindran to help teams improve Fabric Spark price/perf with automated diagnostics + profiling. If you run Spark in Fabric, this will save you time and vCores. christopherfinlan.com/2026/01/05/spa…

My first post of the year is about Fabric. What I thought was a gut feeling has been confirmed and validated by multiple tests. Clearly, what follows is valid for me and may not be valid for other scenarios, even though I am pretty confident that the conclusion about the service cost is accurate. However, I do not have the time or interest to write a whole article about this topic, so I leave it here as a reference. Using 𝗻𝗼𝘁𝗲𝗯𝗼𝗼𝗸𝘀 is the 𝗰𝗵𝗲𝗮𝗽𝗲𝘀𝘁 𝗮𝗻𝗱 𝗳𝗮𝘀𝘁𝗲𝘀𝘁 way to 𝗶𝗻𝗴𝗲𝘀𝘁 𝗱𝗮𝘁𝗮. Pipelines, Dataflows Gen 2, and Copy Tasks are more expensive (CUs) and slower (execution time). 𝗪𝗵𝗶𝗰𝗵 𝗻𝗼𝘁𝗲𝗯𝗼𝗼𝗸 𝘁𝘆𝗽𝗲? Both PySpark and T-SQL work well. I prefer to use SQL for transformation and PySpark for ingestion (and transformations that would not work well in SQL). 𝗖𝗮𝘃𝗲𝗮𝘁: You must use the right approach. LLMs can help you, but you cannot blindly trust them for either the result or the performance. However, with patience, tests, and review, you can get what you want. 𝗜𝘀 𝘂𝘀𝗶𝗻𝗴 𝗟𝗟𝗠𝘀 𝗺𝗼𝗿𝗲 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝘃𝗲? Definitely, yes, at least for PySpark. I wrote notebooks with hundreds of lines of code; I would have definitely spent more time researching and typing code. The savings range from 3x to 10x. It's huge at the very beginning, and it decreases as you refine the code. So, it depends on how and when you measure it. Oh, one last note, just for the future, myself not remembering these details: it's always better to 𝗰𝗼𝗻𝘃𝗲𝗿𝘁 𝗮 𝗖𝗦𝗩 𝗶𝗻𝘁𝗼 𝗮 𝗣𝗮𝗿𝗾𝘂𝗲𝘁 𝗳𝗶𝗹𝗲 𝗼𝗻𝗰𝗲 (and I'm not saying Delta here), then read the Parquet file(s). You will constantly change/refactor the transformation later; the difference is too big to ignore (on the order of one to two orders of magnitude). It will be an interesting year.

Gil Gerard, the actor who starred as the titular hero in “Buck Rogers in the 25th Century,” has died after a battle with cancer. He was 82. "My life has been an amazing journey. The opportunities I’ve had, the people I’ve met and the love I have given and received have made my 82 years on the planet deeply satisfying," Gerard wrote in statement before his death and shared posthumously by his wife. "My journey has taken me from Arkansas to New York to Los Angeles, and finally, to my home in North Georgia with my amazing wife, Janet, of 18 years. It’s been a great ride, but inevitably one that comes to a close as mine has. Don’t waste your time on anything that doesn’t thrill you or bring you love. See you out somewhere in the cosmos." variety.com/2025/tv/obitua…

Late post but got the win in 4OT! Check out some of my highlights from the game hudl.com/v/2T4dbN @CoachTheds @Codyluang3411 @ldelay @loganbruce55

42-23 W over Newport. Didn’t have too many highlight plays but got lots of pressures and affected plays without making the plays. Now time to make a push for playoffs. hudl.com/v/2T0qkN @CoachTheds @Codyluang3411 @loganbruce55 @ldelay
