Fantastic catch! It led me down a rabbit hole, and I finally found the root cause.

The recipe site was so long that it got truncated before being sent to the LLM. Then, based on the first 8000 characters, Gemini hallucinated the rest of the recipe, it was definitely in its training set.

I have fixed it and pushed a new version of the project. Thanks again, it really highlights how we can never fully trust models.

At work we've licensed cursor, but as a vim holdout it's a nogo and we're otherwise somewhat restricted on what we can install.

I have 3 vim commands:

ZB $n: paste the buffer $n inside backticks along with the file path.

Z: Run the current buffer through our llm and append the output

ZI: Run the yank register through our llm and insert the output at the cursor.

The commands also pass along my AGENTS.md

Basically I'm manually building the context. One thing I really like is that when it outputs something stupid, I can just edit that part. E.g. if I ask for a plan to do something, and I don't like step 5, I can just delete it.

One humorous side effect is that without the clear chat structure, it sometimes has difficulty figuring out the end-of-stream. It can end with a question like "would you like me to ...?", answer itself yes, and keep going.

counting things are a huge intellectual blind spot. For some reason, when people hear a figure, they accept it as gospel.

sums, averages, population, budgets, spending, rates.

Counting things is time consuming and error prone. Ask a casino. You can have 3 people count something and come to a different figure off by a few percent.

Seriously if someone says there's $1m in there, who is going to second guess? Thankfully this guy did.

It’s not that small of an effect size relative to the upfront price difference. Subtraction of the initial cost of the non hybrid from both numbers is very reasonable because you know what that is for both.

Also, the payback for a more expensive upfront car at year 5 on a car likely to last ~26 years doesn’t mean they are also equal for the next 21 years.

Over the last 15 years I've worked as an AE/Editor, DIT, Colorist, Online Editor & Post Supervisor and based on my experience I've built a tool that I hope will be useful for some of you!

It's a cinema calculator (aspect ratios, target speeds, target bitrates & more...) called CineMath and it's available for free download in the Apple App Store.

I would be immensely grateful for any feedback and hope that it helps someone in their workflow!

Observability is expensive. Rip/replace is hard... we built grepr.ai to solve this problem and are seeing 96% reduction in spend from Splunk/Sumo/New Relic/Datadog etc. No change mgt. The result set is: 96% reduction in spend and noise elimination. Pretty compelling.. come check us out. www.grepr.ai

> Gives everyone something way better to do with all those nuclear bombs

The counterpoint there is it gives lots of reasons to make so many more, increasing proliferation worries.

However, there's an SF novel that just came out that features nuclear pulse: Fenrir, by Ryk Spoor and (posthumously) Eric Flint. I enjoyed it.

I'm no longer at the company but yesterday was my last day so my information is still current.

The division I worked in was demanding that developers use AI at least once a week and they were tracking people's usage. The boss nagged about it every day.

I had no problem meeting the requirement but did find it's contributions to be very hit or miss as to usefulness.

Hi! I answered this in a few comments but:

The app performs its functions entirely client-side except for the job search to JSearch, which only requires the company name.

How many enterprises want to use two or three generation old second-hand leased servers?

As a homelabber I can see the sense, but as the IT guy at a small company it doesn't sound like a great deal.

If I were in a situation where I needed some physical machines, didn't care how old they are, and budget was an issue, I'd just go to eBay. Just get something cheap and own it outright without some corporation sticking their nose into the process.

I imagine the market segment willing to accept old and refurbed servers, yet requires some SLA from the vendor is not terribly large. Almost all businesses would be better served by owning last generation servers outright or simply using AWS.

Then again, we are talking about an industry that's happy paying tens of thousands of dollars in AWS bills for an application that can reasonably run on a single server from 2016. So there's no inherent logic at play.

> But having a version tree, forking and merging, having to deal multiple timelines and the graphs that represent them -- that's where you lose people.

There's no good reason why that should be the case. E.g., one could imagine the guts of the "copy-pasting files" UI being a VCS. That would keep the original 100% of the userbase plus allow whatever percentage to level up if/when the need arises (or go "back in time" in the event of a major screw-up).

It's just that software UX in 2025 is typically very bad. The real axiom: the longer you run an application, the more likely it will do the opposite of its intended purpose.

Oops, the word "stash" in git has an idiosyncratic meaning. That content has been removed from the history I was trying to keep. Fuck.

Oops, "Start" in Windows pauses interactivity and animation until ads are ready to be displayed in the upcoming dialog. Fuck!

Especially in the latter case, I don't think users are deterred by the cognitive load required to interact with the interface. It's probably more a case of them being deterred because the goddamned stupid thing isn't doing what it's supposed to.

It's the standard definition in a software development context, which you can find all over the place. Here are some examples:

> "Parameters are named variables declared as part of a function. They are used to reference the arguments passed into the function."

-- MDN, https://developer.mozilla.org/en-US/docs/Glossary/Parameter

> "A parameter is a special kind of variable used in a function to refer to one of the pieces of data provided as input to the function. These pieces of data are the values of the arguments with which the function is going to be called/invoked."

-- Programming Fundamentals, https://press.rebus.community/programmingfundamentals/chapte...

> "Parameters refer to the variables listed in a function's declaration, defining the input that the function can accept. Arguments, however, are the actual values passed to the function when it is called, filling the parameters during execution."

-- https://www.geeksforgeeks.org/computer-science-fundamentals/...

While you might be tempted to "do you" and use your own idiosyncratic definitions, I advise against it, since it makes it difficult for you to understand what others are saying, and vice versa.

> Great catch. I was getting ready to mention the theoretical risk of asking an LLM be your arbiter of truth; it didn't even occur to me to check the chosen example for correctness.

It's beyond parody at this point. Shit just doesn't work, but this fundamental flaw of LLMs is just waved away or simply not acknowledged at all!

You have an algorithm that rewrites textA to textB (so nice), where textB potentially has no relation to textB (oh no). Were it anything else this would mean "you don't have an algorithm to rewrite textA to textB", but for gen ai? Apparently this is not a fatal flaw, it's not even a flaw at all!

I should also note that there is no indication that this fundamental flaw can be corrected.

I find the associative nature of our memory can only be represented as a graph, but we definitely need a vector store.

I like to pose this as an identity question rather than memory as colloquially memory is only associated with fact extraction and retrieval, while identity extends that to traits, behavior, preferences, memory and narrative causal relations.

essentially a self organization of symbols and memories to produce a coherent singular entity.

I had written about it here.

Roboflow | Solutions Architects, Implementation Engineer, Developer Advocate, Full Stack Engineers | Full-time (Remote, SF, NYC) | https://roboflow.com/careers?ref=whoishiring0725

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like RF-DETR [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We raised our Series B round at the end of last year, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

No. The bottleneck for me is not the speed at which I type code, which is basically what LLMs accelerate. I've been thinking about trying again, but at this point the context windows are FAR too small to feed my entire project too, and it just seems like a giant pain to have to babysit that.

Additionally, the bottleneck for me is typically writing graphics code, and LLMs are hilariously bad at that.

I can't help wondering how big a cube you'd need to fill it with 1 million $1 coins.

43x43 piles of 541 coins each make 1000309 coins with a pile height of 541*2mm = 1.082m, while the width would be somewhat less than 43*26.5mm = 1.1395m with a hexagonal packing.

So just over 1m cubed, a little smaller than the bill version. But at 8100 kg, tons heavier.

Eh...kinda. The RL in RLHF is a very different animal than the RL in a Waymo car training pipeline, which is sort of obvious when you see that the former can be done by anyone with some clusters and some talent, and the latter is so hard that even Waymo has a marked preference for operating in July in Chandler AZ: everyone else is in the process of explaining why they didn't really want Level 5 per se anyways: all brakes no gas if you will.

The Q summations that are estimated/approximated by deep policy networks are famously unstable/ill-behaved under descent optimization in the general case, and it's not at all obvious that "point RL at it" is like, going to work at all. You get stability and convergence issues, you get stuck in minima, it's hard and not a mastered art yet, lot of "midway between alchemy and chemistry" vibes.

The RL in RLHF is more like Learning to Rank in a newsfeed optimization setting: it's (often) ranked-choice over human-rating preferences with extremely stable outcomes across humans. This phrasing is a little cheeky but gives the flavor: it's Instagram where the reward is "call it professional and useful" instead of "keep clicking".

When the Bitter Lesson essay was published, it was contrarian and important and most of all aimed at an audience of expert practitioners. The Bitter Bitter Lesson in 2025 is that if it looks like you're in the middle of an exponential process, wait a year or two and the sigmoid will become clear, and we're already there with the LLM stuff. Opus 4 is taking 30 seconds on the biggest cluster that billions can buy and they've stripped off like 90% of the correctspeak alignment to get that capability lift, we're hitting the wall.

Now this isn't to say that AI progress is over, new stuff is coming out all the time, but "log scale and a ruler" math is marketing at this point, this was a sigmoid.

I was being polite to the other poster so I can address the more germane claim in their reply without getting derailed by explaining why the less important point was irrelevant. The fact is the series “term of art” in the reliability domain and the hybrid engineering terminology mean the same thing. They are derived from the same concept.

The numbers come from the Edmunds site. Eg fuel cost by locality, 15k miles a year etc. You can look at the site for all their assumptions, but some of it is proprietary.

>But we don’t actually have these [TCO] numbers

Exactly! So why are you making strong conclusions in the absence of data?! This is why it comes across as if you are an ideological argument instead of a data-literate one.

“I don’t have any data, but it just makes sense to me” is not the type of curious discussion I was after.

I am not sure that's an entirely fair comparison, there's plenty of data on how dangerous asbestos is (if it's disturbed - lots of it is hanging around in walls etc. and not causing trouble... yet...) CF is less well-studied, though of course we have lots of carbon compounds in our bodies, unlike scratchy silicates, which might suggest it should cause us less harm. But it'd be good to have the research to confirm that.
