I fail to understand how two LLMs would be "consuming" a different amount of tokens given the same input? Does it refer to the number of output tokens? Or is it in the context of some "agentic loop" (eg Claude Code)?

> Interestingly, the malware checks for the presence of Claude Code CLI or Gemini CLI on the system to offload much of the fingerprintable code to a prompt.

Can anyone explain this? Why is it an advantage?

In the demo, is there any specific reason that the voice doesn't go "up" in pitch when asking questions? Even the (many) rethorical questions would in my view improve by having a bit of a pitch change before the question mark.

At [previous company], we initially required branches to be up to date with main. Since it was a relatively big mono repo, it slowed down productivity quite a bit.

Eventually we tried dropping that requirement and instead relied on testing main before deploying to production. It sped us up again, and main never broke because of bad merges while I was there.

New comment by grav in "Claude 3.7 Sonnet and Claude Code"

grav — Mon, 24 Feb 2025 19:58:14 +0000

Claude 3.7 Sonnet seems to have a context window of 64.000 via the API:

  max_tokens: 4242424242 > 64000, which is the maximum allowed number of output tokens for claude-3-7-sonnet-20250219

I got a max of 8192 with Claude 3.5 sonnet.

It is possible, since spending has an API. I’ve recently implemented it on Azure for a company, to ensure our storage costs didn’t run wild.

Couldn’t find an out-of-the-box solution, maybe, as you say because it’s not in their interest.

grav — Sun, 02 Feb 2025 16:10:42 +0000

Couldn't get the code to run with Perl on Mac:

   $ plenv exec perl midi.pl
   Not enough arguments for main::pedal_notes at midi.pl line 107, near "$note)"
   BEGIN not safe after errors--compilation aborted at midi.pl line 150.

I got something similar working in Supercollider though, which has a lot of tools for these sort of things, eg:

   MIDIIn.addFuncTo(\noteOn, ~myNoteOnHandler);

> no motion data

How come there's no motion data?

Very impressive. Also interesting that the motion type prediction ("is this a moving train?") generalizes to underground trains in other cities.

I see they support the the largest cities in Sweden and Norway, wonder if there are any plans for Copenhagen, Denmark?

TL;DR: created a wifi-network on another phone with same SSID and password as the one that the lost phone usually connects to, walked around waiting for the phone to connect, receive the "Find my phone" notification and send out a sound.

Cool :)

Nice idea. I'm really missing a way to contol the dynamics. Maybe just mapping 1-9 keys to a velocity scaling?

I also experienced performance problems with Arch Linux ARM through UTM. Parallels seems to perform much better for me.

One issue might be that only OpenGL 2.1 is supported: https://github.com/utmapp/UTM/issues/4285

grav — Wed, 16 Aug 2023 12:06:32 +0000

I've been using the trick with enforcing realization by serializing to strings a few times. Slow, but quite useful in many contexts. However, instead of using `(with-out-str (pr ...`, there's simply`pr-str`, which is easier to remember.

I'm typically using it like so:

  (defn realize [v] (doto v pr-str))

  (binding [*some* binding]
    (realize (f some-nested-lazy-seq)))
