    I&#39;ve lived in my house for almost 10 years. One of my exterior doors has been stiff to open that entire time, rubbing on the threshold just as it latches. To my chagrin (and joy!), I _just_ noticed that the door has adjustable hinges! It allows adjustment in two dimensions. A few minutes with a hex wrench and now the door is silky smooth, better than it&#39;s ever been!

    @mjg59@nondeterministic.computer DPoP? Are you looking specifically for a situation where some middleware has leaked secrets of the traffic it is mediating?

    I saw a service offering &quot;115M ethically-sourced residential IPs&quot;. Is there even such a category for ethical residential proxies, or are they all underhanded things and botnets??

    Doing fuzz testing, I&#39;ve seen the same performance bug in parsers for at least 3 systems, where a line number for location reporting is determined from a byte offset by looping through the input, itself done in a loop. Surprise O(n^2)! It probably doesn&#39;t show up easily in &quot;normal&quot; use patterns, but when you start fuzz testing you hit it all the time.

    Aetna sending me an apology email for their AI slop search feature. They are &amp;quot;taking steps&amp;quot; and I can call them to talk to a human. A word extruder answering health and insurance policy questions. What could possibly go wrong??

    I play double bass, but also sometimes play electric bass through headphones after my kids go to bed. It&amp;#39;s interesting to me that I can tell when my ears get tired! After 40 minutes or so, I have a harder time distinguishing between half steps below 60Hz or so... they all start to sound samesies

    The last couple months I have noticed a UI bug on several major websites on mobile: you scroll down a while, then make the &amp;quot;scroll to top&amp;quot; gesture. The page scrolls to the top, but form elements (like a search bar) become unselectable until a full page refresh. My (non-techie) spouse has also noticed this and was complaining about it today! Are all these sites using the same Javascript framework that introduced a bug or breaking change a couple months ago??

    @regehr once pointed out that Anthropic&amp;#39;s logo for Claude looks like something else, and I cannot unsee it now
