Like many programmers, in my early days I was totally unaware how floating point values were stored. Even seemingly simple data structures are worth explaining, especially when debugging.
So I was glad getting referenced to [Wayback/Archive] Float Exposed and to [Wayback/Archive] Floating Point Visually Explained which I will quote a few bits below.
About bits: did you notice you can flick on the float.exposed bits to flip them? Try it!
The references came from replies to [Wayback/Archive] Julia Evans on Twitter: “floating point representation”

Planning and feedback loops in extreme programming
TL;DR:
Using LLM in the software development process is shifting the feedback cycle to the top of the development cycle in the graph on the right. This is a costly endeavour.
LLM deliver output that is statistically likely, decreasing the chance to incorporate outliers as they are statistically unlikely but form the burden of software development.
[Wayback/Archive] Mumbly_Bum comments on AI is working great for my team, and y’all are making me feel crazy
Most of our tickets are now (initially) generated using Claude + the Atlassian MCP, and that’s allowed us to capture missed requirements up-front.
I think this is the key disconnect (even taking into account the notes from meetings) in understanding our jobs and why we’re not going away and why LLMs create harm in delivery.

Ever since Chris Hesik spoke on “RAD Studio 2010 what’s new in the IDE debugger”, wanted to write a blog post about it.
Still haven’t found time to do that in depth, but it’s important to at least jot a few notes, so let’s start with the 20111020 conference session notes.

Interesting strategy that driver vendors use to prevent their drivers to be installed when newer versions are installed [Wayback/Archive] You thought Windows drivers from 2006 were old, wait’ll you see the Intel drivers from 1968! – The Old New Thing
Or in other words: with this mechanism drivers can be a generic alternative to be installed when no more specific or newer driver is available.
Via [Wayback/Archive] ⚜ 8-bit Hero (aka Sven) ⚜ on Twitter: “Wow, Intel has been writing windows divers for a long time! Had no idea.”

Take this cool example I extended from [Wayback/Archive] Thomas 🅰️🇨🇵 on Twitter: “#Typescript quizz What will be the value of result1 and result2 ?” which lacked alt-badge, so I [Wayback/Archive] responded with the image on the right that has alt-text.
Based on that, I added a bit of logging:
const a = undefined;
const result1 = a ?? 0 + 10;
const b = 100;
const result2 = b ?? 0 + 10;
console.log(result1);
console.log(result2);
Two questions:
- What is the output of both log lines?

The first tweet below reminded me that few people seem to realise that const expressions are evaluated by the compiler/interpreter into the actual const value. Often this is called constant folding (though that can happen outside constant definitions too!)
Truckloads of source code I have come across in all kinds of languages where people put the calculated values in the expression like described here:
[Wayback/Archive] Kevlin Henney on Twitter: “For example: const int secondsInDay = 24 * 60 * 60; There is no need to calculate it yourself: const int secondsInDay = 86400; Or, related to what I’ve just seen: const int secondsInDay = 86400; // 24 * 60 * 60“.
In languages that support rich enough types, you can even pass a typed constant like timespan, duration or period around:
[Wayback/Archive] David Kerr on Twitter: “@KevlinHenney The general point is well made of choir course. In java, etc you can pass a Duration object around, no need to interpret an in. Type safety, self documenting.”
My recommendation is to use an expression like the first and maybe document the calculated value (for instance for ease of bug hunting) like here
