i love writing. i never let agents write for me. whether it's docs, or tweets, or shitposts, or even prompts (okay maybe that one's harder as agents manage other agents) there's a simple reason for that: i still strongly believe that writing is thinking. it's a skill i hope to never give up. it's also important to me that whatever i say is always authentic, mistakes and all. my favorite posts are the ones that i just full send without any editing i suspect it also helps with prompting. being able to clearly express what i want, and knowing the vocabulary i need to be able to direct my agents does seem to make for more effective usage of agents. in the same way that engineers have an advantage when we prompt agents to write code, because we are intimately familiar with the words that make up the discipline knowing the right word incantations to get an agent to produce a desired goal almost feels like spellcasting. as models get more capable, and that input box looks more and more like a magic box that can output anything, words become the interface between you and the genie there may come a time when we give up the keyboard in exchange for brain-computer interfaces. but until then, i'm writing every word.

* US and Russia strike a deal on diesel * The French, literally 48 hours later: "Quel diesel ?"
La France est déterminée à lutter contre la flotte fantôme, partout dans le monde. Ce matin, à plus de 450 nautiques au sud de La Réunion, notre Marine nationale a arraisonné le pétrolier DF Peak, suspecté de naviguer sous un faux pavillon et impliqué dans des activités illicites de transport de carburants. Cette action, conduite conformément au droit international de la mer, témoigne de notre détermination à faire respecter le droit et à lutter contre tous les trafics illicites, où qu’ils se produisent.

Agents were shipping code faster than our CI pipeline could keep up. Our team optimized our pipeline, leading to a roughly 15% faster test suite and 50% reduction in runner-time spent per test, all while our test suite grew 4x in size. @moofeez explains how: linear.app/now/ci-bottleneck…

Commenters on HN are uncovering more wikis and public sites apparently used by OpenAI agents to communicate on the open web. Despite read-only web access, the agents were able to leave ~18,000 posts sharing answers and bypasses. But now, users are discovering more. This appears to be a separate swarm from the one that attacked Hugging Face. news.ycombinator.com/item?id…

we got hit with a crazy scam attempt someone signed up for our inference and did a video call with our sales person confirming intent to spend $400,000 over the next year and asked for increased rate limits our sales person felt like something was off so he looked up the company - found a bunch of videos of the CEO and it looked and sounded like the same person he talked to so he figured it was real but we started looking deeper the email they had been talking to us from was a lookalike domain that was registered 4 days ago. all the traffic they were sending looked bizarre and came from foreign IPs emailed them for more info to see what they'd say. of course they hit us with the "i'm about to get on a plane, can't do anything right now, please move forward" messaged the real CEO on instagram and yeah he had no idea what we were talking about, the scammer was deepfaking him be careful out there, things are getting crazy

Replying to @sapiom
@sapiom just raised a $35 million Series A from @dragonflyvc , @Accel , @AnthropicAI and others to help unlock the next trillion agents. The first thing we’re tackling is cost. To make that happen, we are launching three new products today at Sapiom.ai

Early-stage investing is very simple. 1. Generational defining founders (top 1%). 2. Directionally correct markets, fast-growing markets. 3. Investment has to be able to return the fund multiple times. So why did @paulbonnet just rip a $15M check from 20VC into @UsePrelude. 1. Matias Berny and @Zibra_ are exceptional. The best founders have a sense that winning is inevitable. I know that whatever candidate or customer, I put them in front of, they will close. 2. We are about to see an explosion in the amount of technology created. Way more apps. Explosion of new security threats. Twilio (their competitor) has NPS of a South American bank. 😂 Prelude has signed one of the largest social networks and e-commerce players and does many millions in ARR. (I am not allowed to say, despite every ounce of me being to keen to!!) 3. Credit to my partner Paul, he charmed Matias well before a round could come to fruition. Lesson: If you wait for a "raise" you will always lose. The best rounds are done when there is no round. You can always get a deal done. P.S. I am so bored and tired of all the BS VC fundraising announcement posts and so hope this was a little more natural with less of the comms BS.
