@eircare Could I ask you about IPv6 prefix allocation on our eir Fibre? I have sent you a DM but I am not sure if that is the best way to contact you. Thanks.

My first comment to the "create a measure description with Copilot" feature just released in #powerbi. PREAMBLE I haven't seen any LLM writing decent DAX so far - they're barely good for a demo, but they are not helpful in the real world. However, I was impressed by ChatGPT-4's ability to explain existing DAX code. Thus, I'm not impressed by the good (but not excellent) results achieved by Copilot. MY NOTES - It works well when measures, tables, and columns have meaningful names: in these conditions, it can extrapolate the "meaning" of the measure and not just an English translation of the DAX code. - When names are not so clear and/or you use acronyms, it is less good. E.g. "Previous Month" is easier to understand than "PM". However, it understands MOM (Month Over Month) and YOY (Year Over Year). - It seems not to inspect the content of the referenced measures. I'm not 100% sure, but so far, I would say that it understands the behavior of a referenced measure just by its name, not by its internal DAX formula. - When you use USERELATIONSHIP, it never understands the meaning of what is happening. Writing in the description that it activates a relationship is not helpful to the user who does not see the diagram view. CONCLUSIONS If you use it to describe the measures you know, it saves you time. A lot of time. I would like to control the style: what's the point of starting each sentence with "The 'xyz' measure calculates..."? Just use "calculate". A dictionary with custom acronyms would be helpful. Customizing the prompt with additional instructions would help, too. It would also be helpful to create the description for multiple measures at once, editing them in a table (in Excel, why not), and then apply them all at once. For consistency, you might want to switch back and forth between different measures. The entire point of this feature is to increase productivity - reducing the needed clicks and actions is part of that journey. powerbi.microsoft.com/en-us/blog/gen…

Leila passed away 8 am today 31st if December 2023. I never have seen anyone suffering so much yet be always positive She was the symbol of bravery and strength She was a loving wife, best friend, tech guru, and most importantly an amazing human being. In my life I am honored to call her not only my life partner but also mentor. Our world was very small for her big heart I had the privilege of being with her for 17 years, the best years of my life She endured unbearable suffering in the past 11 months. She is in peace now, no more pain for you. Such a big loss for me, your friends, the global Microsoft community and anyone who knew him.

@marcorus @arcticdba The best system is a single question such as “Did you like it?” or “Pleased?” or “More like this one?” etc with just two answers, “Yes” and a “No.” Any multi-valued answers, like the 5 percentage bands, yield significantly poorer data quality. Plus additional free text comments.

Nothing is perfect. But I prefer 100 answers to one question (increasing the chances of text feedback) rather than 10 answers to 5 questions. Max number of questions for a session is 3, above that the correlation between answers is too high and it becomes meaningless. Talking by experience in organizing conferences and handling feedback. Clearly, mileage may vary, this is just my 2 cents.

Hey, conference organizers, this is the best session feedback form I have *ever* seen in many conferences around the word in many years. 1) it’s on paper, volunteers collect them at the end of the session. each attendee received the sponsor’s bag in the morning with mktg material, a pen, and a block of feedback forms with a rigid card in the back to simplify writing if you don’t have a plain rigid surface. 2) it’s a one question only with a no-brainer way to define good and bad score 3) the effort requires to the attendee is minimum: write session code (which could be recovered is missing as all the feedbacks for the same time slot/room are collected in the same bag, so there is a fallback system to retrieve the missing code) 4) if the attendee want to provide additional feedback, there is space to do so. For conferences where each session has less than 200 attendees, collecting feedback on paper is the only way to get a statistically significative data sample. We love data, but rule #1 is to get good data. Keep it simple, keep it productive, keep it relevant. Good job #doh23 (DevOps Heroes Parma 2023)!

#OTD 79 years ago the Warsaw Uprising begins in 1944. Polish Home Army units rise up and storm Nazi positions in and around Warsaw, intending to hold the city until they can be relieved by the advancing Soviet Army. Unfortunately the Soviets halt and allow the Polish units, thought by the Soviets to represent a danger to their plans for a communist puppet government post-war, to be slaughtered. British & American forces conduct a belated and half-hearted attempt to support the effort with long range supply drops. The Poles hold out for 63 days, suffering as many as 20,000+ combatant casualties in addition to 150-200,000+ civilian casualties. The majority of the city is subsequently reduced to rubble. I highly recommend following @WW2girl1944 if you're interested in an in-depth accounting of this engagement, and Polish military history during WW2 in general.

I realise this is not supposed to be funny. However, if you watch, make sure to see what happens in the background. Anyways, I never thought that wearing a💂‍♂️hat will count as bravery. youtube.com/watch?v=bZj8iU…

@bob_duffy @DOtykier @mim_djo And at the beginning there was SQL. And at the end there will be SQL. Many amusements in between, some even temporarily useful, but not durable.

We will miss him. Paul O’Grady and Lily Savage, not necessarily in that order, helped me gain confidence to be myself in the world that did not yet care enough. We are lucky now and here ☘️ and I hope the future is bright 🌈 everywhere 🌍 theguardian.com/commentisfree/…

Gordon Moore, who predicted rise of the PC, dies at 94. “It sure is nice to be at the right place at the right time”. I have a feeling many of us who have been in IT for a while would say the same. Pity about the recent, perhaps even premature layoffs. theguardian.com/technology/202…
