Hey "seniors":

Ask "stupid questions" where your juniors can see you asking them and getting answers from other people. Don't make juniors feel alone in not knowing something and being the only ones asking for help.

This study includes ALL THE FIRST AND SECOND GRADERS ENROLLED IN SCHOOL IN FRANCE

"the gender gap increased with schooling rather than with age. These findings point to the first year of school as the time and place where a maths gender gap emerges in favour of boys"

Rapid emergence of a maths gender gap in first grade - Nature

Boys and girls exhibit very similar maths scores upon school entry, but a gender gap in favour of boys becomes highly significant after 4 months of schooling, which increases with years of schooling, independently of age.

#webdesign and #webdev folks:

How often do you use fixed breakpoint media queries in your CSS?

By that I mean set breakpoints based on the browser viewport, whether they use relative units or pixels. Also let me know if you use a predefined list of values for small/medium/large sizes, or different breakpoints for different elements.

(Please boost for a better sample size)

All the time
Fairly frequently
Very rarely

Shower with Your Battlemat?

Yes, you should indeed shower with your battlemat. Find this and other tips as I add my review of the time-tested Chessex Battlemat.

Mastering Dungeons is on vacation this week! We will be back next week.

This Thursday! Come hear @caius expound the virtues of tugging on those mysterious threads that we happen upon during our day to day code weaving #ruby

NWRUG Event: Tugging threads, Thursday 17th July

After last month's Brighton Ruby break we're back for another edition of Ruby in the North West, AKA NWRUG. This month we have our very own Caius (https://ru...

We are back! #C64 https://www.commodore.net/ The first official Commodore 64 in over 30 years is here - a faithful recreation of the original motherboard on FPGA hardware. HDMI, WiFi, USB, but compatible with every existing cartridge and peripheral. Not an emulator - a recreation. Same price as my first $299

It’s so frustrating that there is this illusion that we are all 49%/49% right now. Us versus them, good versus bad, and it’s all because of the BS that is the electoral system. It’s very likely 70% versus 30% and we’re just not seeing representative government.There’s just no common sense right now

With the clarity of hindsight, it's fine to say Honda would obviously nail a reusable rocket test

But, I don't think anyone outside the company actually expected this. Honda has a history of venturing out to experimental work E.G. robotics, but this is totally new

MCP is doing the heavy lifting here. I've written two "agentic" apps. I immediately realized I could improve both by replacing the LLM part with normal fucking code. The revolution here is MCP shoehorning API access into many more programs and services than we previously had https://worksonmymachine.substack.com/p/mcp-an-accidentally-universal-plugin

Reflecting on an incredible experience speaking at @TheLeadDev's #LDX3 conference last week! Very grateful to have been accepted as a speaker and for the amazing support throughout.

I enjoyed discussing challenges growing teams in the era of layoffs, and hopeful that my talk can provide some inspiration by treating teaching as a core engineering skill, applying lessons from pedagogy.
