I get really annoyed when a link unexpectedly takes me to X, but since I ended up there today, this is too good not to share.

AI literally Rickrolled a company's customer when they asked for a link to a training video! It replied to a request by sending a link to Rick Astley's video on YouTube.

day gets better

We're 7 years after the publication of NIST 800-63 on best practice guidance for modern passwords and I still talk to large companies stuck in the past trying to enforce silly password rules and mandatory 90 day rotations. Pretty sure I'm still going to be having these discussions at the 10 year anniversary.

As I mentioned a number of times, I take good care of the discoverability of my content, which includes #SEO. At the same time, my personal homepage is comfortably low traffic and updates rarely, allowing me to easily spot how Google cheats.

This image shows the ratio of indexed/unindexed pages - as you can see Google just decided not to index thousands of pages.

At the same time, my clicks look great, in part because Google counts clicks to other pages that host the same/similar content (this also results in falsely reported in-links) to my site. I wouldn't be surprised if these clicks were doubly counted to pump numbers...

Google's removal of the estimated number of search results is particularly user-hostile.

And it's me. I'm "user".

There's a specific kind of searching where you know that there shouldn't be a ton of results, and you are adding exclusions until your search matches the expected result space.

And now that's impossible (without scrolling to the bottom to see how many pages of results there are).

Some thoughts on memory safety

https://pacibsp.github.io/2024/some-thoughts-on-memory-safety.html

This post briefly describes some theoretical aspects of memory safety that feel important to me but that aren't always obvious from how I see memory safety being discussed:

1. Memory unsafety is a specific instance of a more general pattern of handle/object unsafety

2. Memory unsafety is relative to a particular layer in a stack of abstract machines

3. Memory unsafety matters because it violates local reasoning about state

4. Safe languages use invariants to provide memory safety, but these invariants do not define memory safety

Also, not sure what was up with the embed in my last post, hopefully this one works.

Another SolarWinds RCE vulnerability…

… I instantly had the image from Hunt for Red October when the Soviet ambassador tells the US SecState that they needed help and SecState says "Don't tell me you lost _another_ submarine!"

I have some words for the developers who decided that it was completely reasonable to expect a user to be able to precisely hit a single pixel to be able to resize a window.

I've seen this on both Windows and Linux. 🤦‍♂️

Andy Jassy talks about the benefits Amazon is seeing from their AI coding assistant. It’s widespread that devs are more productive with these tools.

The question is whether this is like accountants and Excel where it creates jobs or travel agents & the web where it kills them.
