before the internet was a corporate hellscape it was built by ordinary people! the slop was wacky and homemade just like mom (and David) used to make. alas the good old days are over but I can't believe how lucky we are to have @archive.org to remember them :') web.archive.org/web/20080803...

"openai.com" was once the personal homepage of a guy named glenn (2001), and "tiktok.com" was the quaint shared homepage of a couple as their relationship progressed from dating to married with a baby (2000). THREAD!!!

This is so tragic it's actually incredibly funny
The parents in the study were interested in the toy's potential to teach language and communication skills.

However, their children frequently struggled to converse with it. Gabbo didn't hear their interruptions, talked over them, could not differentiate between child and adult voices and responded awkwardly to declarations of affection.

When one five-year-old said, "I love you," to the toy, it replied: "As a friendly reminder, please ensure interactions adhere to the guidelines provided. Let me know how you would like to proceed."

AI toys for young children need tighter rules, researchers warn
In first study of its kind, Cambridge researchers found AI toys could misread some children's emotions.

Seeing people use LLMs to generate entire documents feels kinda bad, but I've struggled to express *why* exactly it feels bad. I think this articulates it really nicely — it's about trust.
Excerpt from https://rfd.shared.oxide.computer/rfd/0576, with a passage highlighted: "our writing is an important vessel for building trust — and that trust can be quickly eroded if we are not speaking with our own voice."

Full text:

If, however, prose is LLM-generated, this social contract becomes ripped up: a reader cannot assume that the writer understands their ideas because they might not so much have read the product of the LLM that they tasked to write it. If one is lucky, these are LLM hallucinations: obviously wrong and quickly discarded. If one is unlucky, however, it will be a kind of LLM-induced cognitive dissonance: a puzzle in which pieces don’t fit because there is in fact no puzzle at all. This can leave a reader frustrated: why should they spend more time reading prose than the writer spent writing it?

This can be navigated, of course, but it is truly perilous: our writing is an important vessel for building trust — and that trust can be quickly eroded if we are not speaking with our own voice. For us at Oxide, there is a more mechanical reason to be jaundiced about using LLMs to write: because our hiring process very much selects for writers, we know that everyone at Oxide can write — and we have the luxury of demanding of ourselves the kind of writing that we know that we are all capable of.

So our guideline is to generally not use LLMs to write, but this shouldn’t be thought of as an absolute — and it doesn’t mean that an LLM can’t be used as part of the writing process. Just please: consider your responsibility to yourself, to your own ideas — and to the reader.

This is such a bizarre headline for something as simple as “Costco locations close for Memorial Day”

I think about this like once a week
Screenshot of an old tweet from @iamdevloper on April 13 2015:

“How to choose between rem and em”
 
1. question css
2. question your life
3. throw away laptop
4. scamper into forest

Many in tech value brutal honesty, but people often focus more on the brutality than the honesty, making them defensive. Instead, aim to be “direct yet kind.” Start with curiosity and a desire to help before offering criticism. When others see empathy in your words, your feedback is more effective.

Foxes In Love @foxes-in-love.bsky.social · 09/11/2023
A comic of two foxes, one of whom is blue, the other is green. In this one, Blue is complaining about his job, inaudible because Green is not paying attention. Green has his eyes closed, meditating instead.
Green: I must not suggest solutions. Solutions are the vent-killer. I will face the vent. I will permit it to pass over me and through me. And when it has passed, I will see its path, and there will be nothing. Only we will remain.

Blue has reached the end of his string of complaints, looking at Green with a frown as he finishes. Green looks at him, deeply focused.
Blue: ...And that is why my job sucks.
Green: Yes.
