11th June 2024 Kurt Buhler Youtube Video A good video on report design in Power BI (but applicable to other tools as well) which condenses decisions on layout based on informational importance into the 3:30:300 rule, where each multiple of 3 corrsponds to the time in seconds it should take a report's consumer to do certain things with it.
10th May 2024 Derek Comartin Youtube Video "You shouldn't have business logic in your database/code" is something you hear a lot. You may or may not agree (I can see the issues around maintanability but sometimes it's unavoidable), but at the very least you should distinguish business logic from vanilla data validation. Derek Comartin of CodeOpinion.com gives an excellent 10-minute overview of how to do this. His language of choice is C# and his video is very devvy, but this is eminemtly important for and transferrable to data analysts working with code or no-code.
29th April 2024 Noonan Labs Youtube Video Short and sweet overview of Python-based analytics of economic indicators with code provided as well as links to available public data on US economic indicators.
25th March 2024 Katie Bauer Data Blog Katie is on the money here in her blog post from New Year's Eve last year (committment right there) about SLOTHs (Statistical, Logical, Over-Thinking Hesitators).

23rd March 2024 London Data Viz Data Viz Meetup Meetups normally live in the Events and Meetups Calendar section but this group is accepting new members and promoting events via its mailing list rather than Eventbrite or Meetup.

16th February 2024 Layoffs.fyi Surveys and reports Fresh on UCOVI's radar is Layoffs.fyi, which is a website of crowd-sourced data on employees made redundant at tech companies over the past 2 years. It has some basic time series charts showing a decent pattern of economic growth and stagnation in the tech industry, but the gold is in the accessible Google Sheets files for each company that discloses the job titles of those laid off. (It has their names and emails as well which has to be some kind of data breach, but hey, GDPR schmee-DPR.) A great resource for personal-portfolio data projects and for assessing how vulnerable different data roles might be in the current economic climate.
26th January 2024 Alex Mancini Youtube Video Canadian data consultant Alex Mancini offers a slightly sobering 23-minute summary of data jobs in 2024 and the coming years, intimating that we might have hit peak data-bro hype in 2019.
22nd January 2024 Luke Barousse Youtube Video UCOVI fave Luke Barousse has added three new videos this month to his channel on tools and learning priorities for data analysts in 2024. Mostly obvious tips (SQL/Python/ChatGPT and fellow travellers), but they make for a useful, broad summary when watched on 1.5 playback speed.
30th December 2023 Visual Capitalist Data Viz Visual Capitalist - who frequently come up with excellent data viz pieces that catch the eye of UCOVI Best of the Rest - have released their best of compilation for 2023... and have produced a bit of stinker. It's full of either designery bar charts with sepia glows that give answers we could guess for ourselves, or gimmicky and insightless visual comparisons. Apparently if you stacked all the empty office space in New York vertically it would be as high as Mount Everest. So what? We've added this to Best of the Rest because data viz competitions such as the IIB Awards also judge work in this way. As such it's a timely reminder to citizen data analysts not to get their hopes up entering these competitions for recognition of interesting data projects. Their judging panels prefer treemaps framed by shopping trolleys showing which countries have the most Costco branches.
4th December 2023 Visual Capitalist Data Viz Visualising global population density by showing what countries people would be in if the world were 1,000 people. Amazed no-one has tried this before.

11th August 2023 IBM Youtube Video A ten-minute explainer on how much data breaches cost organisations in different industries, how they happen, and effective prevention strategies. The video is a precis of a 78-page Cost of a Data Breach Report produced by IBM from a survey of 500 breached-companies, which is a wealth of detailed and practical insights and is linked to the Youtube video. Somewhat ironically for a report on data breaches, the cost of downloading it is of course your own personal data (email, phone number and organisation).
3rd August 2023 Milos Popovic Data Viz A simple but styling and impactful heatmap viz on regional unemployment in the EU from Milos Popovic on Twitter. Basically get as far away from the Mediterranean Sea as you can if you want to be in work.

This is a groundbreaking article that tackles simultaneously the subjects of data-analyst job satisfaction and over-saturation of BI tools. "We're having a Henry Ford moment, and we need to stop yearning for faster horses."
