xx <- ... is my garbage variable name. My instincts are to just use x, but my instincts also tell me I probably have used x in my actual code somewhere important

One of my first jobs paid me with an actual handwritten cheque each fortnight. I had to sheepishly ask the office manager what to do with it, then was horrified to learn that I had inherited a chore each fortnight to cash it and get my money.

β€œIf I could put it into a very few words, dear sir, I should say that our prevalent belief is in moderation. We inculcate the virtue of avoiding excesses of all kindsβ€”even including, if you will pardon the paradox, excess of virtue itself.”

Hello πŸ‘‹ I will soon have capacity to take on an additional project or engagement. If you, or someone you know are ramping up their #datascience capability, get in touch.

Easiest method is DM, email, stopping me in the street, flagging me down in moving traffic, or failing that, telephone.

I'm not trying to be difficult here. I'm just holding GenAI to the same standard as a cooking recipe book.

...people can and should decide themselves on how to describe what they do. This might be different to what their employers 'brand' them ( often arbitrary). And in any case, many of us end up taking on tasks that don't neatly fit into any definition - and this can be satisfying or necessary.

It sounds like a scientist of some sort. I think the specific job title would depend on the employer's industry and domain. Ive found in different industries, specific titles can be rich with meaning and be very different to equivalent activities in other fields.

'Arrogance is astounding': Microsoft subscription price hike brings backlash Microsoft has increased the price of its Microsoft 365 subscriptions, which it says has new AI features, but the price hike caused consumer outrage.

AI is a bust: www.abc.net.au/news/2025-02...

Contrast this with an actual game changing technology like social media - people were fanging for accounts. Parents were asking their kids to help them get online. Nobody was forced onto social media, and charged an extra 40 bucks for privilege.

Ever look at reviews online? Don't be fooled by average star rating - the number of reviews matters too! ⭐ ⭐ ⭐ ⭐ ⭐ (2)

πŸ’‘ The higher up you are on this chart, the higher your chance of a really bad stay. It turns out you really need 20+ reviews before you can rely on the star rating

I love the way academic papers in the mathematical sciences really ground you before confounding you. First line in the Introduction: "Many of us are familiar with fruits and vegetables"

A favourite restaurant of our family has a menu item which reads: "Chicken Parmigiana with chips and salad or vegetables" and the logical ambiguity is so good we talk about it every time we visit.

I was wondering this too. My skepticism of this was piqued with the phrase 'Existing-Policies Scenario'. Scenario based forecasts are very different to predictions. And lower end estimates of these might just be naive 'status-quo' or no-change scenarios.
