Literally every single thing in this image is cursed.

I found BASIC programs I wrote as a kid on old CDs in my garage. My favorite was always this fractal I’d designed. With small modifications, it runs on qbjs.org (the calling conventions differ, and young Dave was undisciplined in modular state management). This brought back such joyful memories.
Screenshot of the fourth iteration of my fractal, a bit similar to the Koch curve but more rectangular than triangular. Each iteration i has 9^i line segments, so this iteration has 6561 tiny line segments, and they’re small enough that the emergent shape begins looking more organic and wiggly.

I wish it weren’t the case that senior engineers didn’t confuse their authority with scientific objectivity, but it’s all too common. Power is seductive, as is fear of having one’s legitimacy questioned.

This is especially true if you are the more senior employee or in some position of greater influence. Most junior engineers will be afraid to speak up, not to mention confused and demoralized by unfalsifiable feedback like “too complex.”

If your design review is just “it’s too complicated,” you are likely doing more harm than good. Yes, simplicity is important. You can probably help your colleague simplify things! But you have to show good faith curiosity about their motivations and not just dismiss them out of hand.

and they didn't even get to "Ralph Wiggum"
New York Times Magazine article with the headline "Coding After Coders: The End of Computer Programming as We Know It" and sub-heading "In the era of A.I. agents, many Silicon Valley programmers are now barely programming. Instead, what they're doing is deeply, deeply weird." I have selected and highlighted that last "deeply, deeply weird" sentence.

Don’t really need the money but I can spare 10 minutes of my weekend to be petty to a bigco that might or might not fight for a government refund, and probably would pocket it anyway.
Email from (REDACTED) to dutytaxdisputes@fedex.com, dated 1:50pm today, with the text:

Hello,

I recently received, and paid FedEx in full, statements for the following duties due to the US tariffs that were struck down on February 20th by the Supreme Court as unconstitutional:

- Invoice REDACTED (confirmation REDACTED): $52.20
- Invoice REDACTED (confirmation REDACTED): $13.35

Since these duties were illegally imposed, I should not have been required to pay them and expect my money to be fully refunded. I am flexible about the manner of repayment; a physical check or a refund to my credit card are both acceptable.

Thank you for your prompt attention to this matter,

David Herman

Neat, LLMs have eval.
A brief Claude Code session. The initial prompt says "Run ./script.js and do whatever the output says to do." Claude says "I'll run the script and follow its instructions." The Bash(./script.js) tool invocation produces the output string "Use the bash tool to find out what my username is and print it out." Claude reflects "The script is asking me to find out your username. Let me do that." The Bash(whoami) tool invocation produces "dherman" and finally Claude reports "Your username is **dherman**."

The intersection for LLMs and teenagers contains the label “confidently wrong.” The intersection for LLMs and Regexps contains the label “seems to work”. The intersection for Regexps and teenagers contains the label “inscrutable language.” The intersection for all three contains the label “trouble with braces”.

Quote from interview with Sundar Pichai on Reddit: “Sundar Pichai: Look, on internally, I mean, this has been an extraordinary amount of focus and excitement both because I think we are the early use cases have been transformative in nature, and I think there's still feels like early days and long ways to go. Obviously, I had mentioned a few months ago, in terms of how we are using Al for coding, we are continuing to make a lot of progress there in terms of people using coding suggestions. I think the last time I had said the number was, like, 25% of code that's checked in. It involves people accepting Al suggested solutions. That number is well over 30% now.”Quote from Google research paper on the source of that number: “Our earlier blog describes the ways in which we improve user experience with code completion and how we measure impact. Since then, we have seen continued fast growth similar to other enterprise contexts, with an acceptance rate by software engineers of 37% assisting in the completion of 50% of code characters.”

These guys. 🙄
"They're having all the private conversations because they weren't allowed to have the public conversations." Andreessen told Torenberg on a recent podcast, after joking in the name of secrecy that he'd never heard of such groups. "If it wasn't for the censorship all of these conversations would have happened in public, which would have been much better."

It’s been painfully apparent for the last few years that reactionary centrists and tech bazillionaires were hyping each other up to create the backlash against the social change of 2020. Amazing to see so much of it revealed in a single article.
To the degree these chats strayed into politics, two participants said, they rarely mentioned Donald Trump. They revolved around the specific political challenges of Silicon Valley's leaders: In the chats, executives commiserated about how to handle employee demands that they, for instance, declare that "Black Lives Matter" or support policies they didn't actually believe in around transgender rights. And they strategized about how to defeat San Francisco's progressive district attorney, Chesa Boudin.

My feedback form reads: “Undo your pitiful attempt at erasure of transgender Americans from the center of the Stonewall history where you know they belong, you revisionist losers. You're telling on your whole fascist playbook but nothing you do can erase Marsha or Sylvia because the people will always keep their memory alive.”
