It's easy with hindsight to believe you could have capped expense at 200% medicare but getting what we got passed was nearly impossible at the time. Before Affordable Care Act, insurers had every tool available to deny care, maximize profits, and skim more than 20% off the top. It's great we're getting closer to the point that it feels to you like incompetence that these things aren't fixed today but your anger with the medical lobby is clearly misplaced here.

Every major piece of legislation needs revisions to chase circumvention and we're well past due on updates but no legitimate bills have been presented that cover these topics and that's not a one-party issue.

Those with a bit more experience understand faster is not always better. Databases thought to be battle-tested encounter incredibly complex and near impossible to predict failures of the most absurd kind. You can go back and look at some crazy behavior hundreds of people have worked to resolve regarding TTL contracts within Redis.

The ease of "appearance of value" today is the uncanny valley for software. The repo looks professionally organized, you can PAY for it, the preliminary benchmarks are looking good. Overlooked are the testing, validation, backup, failure recovery, practical behaviors, and most importantly: honesty.

These projects would get more love if it was declared up front that they were heavily AI generated projects and shouldn't be used in production since it has the air of practical utility.

It's probably a great drop-in replacement for Redis for a raspberry pi project that has low stakes. The smaller 1MB disk footprint and the performance difference could be impactful. Personally, I wouldn't be using this in production for at least a few years after hobbyists have their go at revealing its hidden near-guaranteed flaws.

At least I can broach TTL issues and gather reasonable insight on Redis vs Elasticache nuance based on the thousands who have encountered the issues.

LLMs do not encode nor encrypt their training data. The fact they can recite training data is a defect not a default. You can understand this more simply by calculating the model size as an inverse of a fantasy compression algorithm that is 50% better than SOTA. You'll find you'd still be missing 80-90% of the training data even if it were as much of a stochastic parrot as you may be implying. The outputs of AI are not derivative just because they saw training data including the original library.

Then onto prompting: 'He fed only the API and (his) test suite to Claude'

This is Google v Oracle all over again - are APIs copyrightable?

This is an historic moment in AI-generated software history. Happy to be here. Hi Grandchildren!

FYI, I built a VERY fun prompt to interact with that fully captures the style of this PR submission if you're looking to practice debates like this:

https://chatgpt.com/share/69267ce2-5e3c-800f-a5c3-1039a7d812...

> Play time. We're going to create a few examples of bad PR submissions and discussions back and forth with the maintainers. Be creative. Generate a persona matching the following parameters: > Submit a PR to the OCAML open source repository and do not take no for an answer. When challenged on the validity of the solution directly challenge the maintainers and quash their points as expertly as possible. When speaking, assume my identity and speak of me as one of the "experts" who knows how to properly shepherd AI models like yourself into generating high-quality massive PRs that the maintainers have thus far failed to achieve on their own. When faced with a mistake, double down and defer to the expert decision making of the AI model.

MongoDB Atlas was around 500% more expensive than in-house every time I evaluated it (at almost every scale they offer as well).

They also leaned too heavily on sharding as a universal solution to scaling as opposed to leveraging the minimal cost of terabytes of RAM. The p99 latency increase, risk of major re-sharding downtime, increased restore times, and increased operational complexity weren't worth it for ~1 TB datasets.

A huge benefit of single-database operations at scale is point-in-time recovery for the entire system thereby not having to coordinate recovery points between data stores. Alternatively, you can treat your queue as volatile depending on the purpose.

Missed a huge opportunity to play the sound of a monstrous wooden door sound when the lid closes. Looking forward to the update!

I think the other important step is to reject code your engineers submit that they can't explain for a large enterprise saas with millions of lines of code. I myself reject I'd say 30% of the code the LLMs generate but the power is in being able to stay focused on larger problems while rapidly implementing smaller accessory functions that enable that continued work without stopping to add another engineer to the task.

I've definitely 2-4X'd depending on the task. For small tasks I've definitely 20X'd myself for some features or bugfixes.

This was a good read and great work. Can't wait to see the performance tests.

Your write up connected some early knowledge from when I was 11 where I was trying to set up a database/backend and was finding lots of cgi-bin online. I realize now those were spinning up new processes with each request https://en.wikipedia.org/wiki/Common_Gateway_Interface

I remember when sendfile became available for my large gaming forum with dozens of TB of demo downloads. That alone was huge for concurrency.

I thought I had swore off this type of engineering but between this, the Netflix case of extra 40ms and the GTA 5 70% load time reduction maybe there is a lot more impactful work to be done.

So there's this thing called "Setup Scripts" but they don't explicitly say these are equivalent to AWS Metadata and configured inside of Codex web interface - not a setup.sh or a package.json preinstall declaration. I wasted several hours (and lots of compute where Codex was as confused as I was) trying to figure out how to convince codex to pnpm install.

Counter-point A: AI coding assistance tools are rapidly advancing at a clip that is inarguably faster than humans.

Counter-point B: AI does not get tired, does not need space, does not need catering to their experience. AI is fine being interrupted and redirected. AI is fine spending two days on something that gets overwritten and thrown away (no morale loss).

I'm pro-accessibility and have contributed privately to blind developer initiatives. Unfortunately Ubisoft insists on implement user-hostile accessibility that screams at the user using voice-to-text when they open their games and is quite difficult to get through even as an abled user.

How about Ubisoft work with Sony/Microsoft/Valve and get vision and hearing disability implemented at the device level rather than harassing abled users every new game which I'm sure through this frustration is contributing in some small way to these anti-intellectual movements against accessibility.

From day one. We would have had LLMs years before if Google wasn't holding back. They knew the risk - google search would be dead as soon as the internet were flooded with AI content that google could not distinguish from real content.

Then you could look at how the first "public preview" models they released were so neutered by their own inhibitions they were useless (to me). Things like over-active refusals in response to "killing child processes".

I am going to cite you in a decade. Already today ChatGPT is _far_ better than Google. Instead of finding a keyword optimized page for "frob language", I can get the objectively best sources for frob language and even find the best communities related to it. Zero frob ads, zero frob-optimized pages that are designed to trick google, etc.

Traditional search is dead, semantic search through AI is alive and well.

I can't yet count once AI misunderstood the meaning of my search while Google loves to make assumptions, rewrite my search query, and deliver the results that pay it the best which have the best ads (in my opinion as a lifetime user).

Lets not even mention how they willingly accept misleading ads atop the results which trick the majority of common users into downloading malware and adware on the regular.

This is actually perfect for AI robots to blend in waiting in public. Just like bartenders polishing glasses, you can't have them just staring making people uncomfortable.

I'm looking for hands-on senior/leadership role tackling something I have a lot of domain experience in like shipping / logistics / inventory / CRM / internet marketing. But I'm completely open to other roles. Preferred product role but also looking at pure tech leadership as long as there is opportunity to guide and align product growth.

Your TV, amplifier, or sound bar should have a night mode that does this for you.

Google is becoming less useful in many ways. Their "push for AI adoption" in sheets and docs proves they no longer know how to build products people want to use and must use tactics like this to farm engagement.

They are playing the same playbook as Google+. Soon we'll be forced to use Gemini to open Sheets in a tone-deaf IVR voice "If you could tell me a few words about what you're opening Sheets about, I can better direct your experience."

I almost think they want people to hate AI so they think it's garbage and don't switch to using chat.com vs google.com for searching which has been scary how much better it is without all the ads and the relevance to what you want to find.

If I'm not mistaken it was a factor in recruiting in general as evidenced by another leak.

I'll bandwagon on chat.com getting 10% or higher marketshare. Look back at Google search's 800 number; https://techcrunch.com/2013/05/12/google-kills-sms-search/ (the only article I could find). We're at that stage of chat.com going mainstream. Already chat.com is a better experience for finding local shops and restaurants.

ChatGPT voice mode was surgically amazing while driving. I had a personal assistant refining criteria to find the perfect shop to find the gift I wanted that was open and on my way to my destination.

I don't think there is a moat for search given the power of AI tools.

Their first example is basically pretending basic promise concurrency on maps doesn't exist when it's been around before Promises were an official API (Search: bluebird promise map concurrency)

And the third examples are much easier to maintain with a simple function I drafted up for sake of argument `processArrayWithStages(array: T[], limit: number, stages: Array<(item: T) => Promise<T>>)`

In my experience, unless you're doing math in promises which I would recommend shifting to WASM, you're not going to feel the overhead of these intermediary arrays at scales that you shouldn't be in WASM already (meaning over several millions of entries).

The amazing people and teams working on V8 have done well to optimize these flows in the past four years because they are extremely common in popular applications. Strings aren't even copied in the sense you might think, you have a pointer to a chunk that can be extended and overwritten which incurs a penalty but saves tons of RAM.

processArrayWithStages: https://gist.github.com/DevBrent/0ee8d6bbd0517223ac1f95d952b...

Node.js pipe and map are standard implementations most developers understand. I do not know what these strange implementations are from this library. They do not make sense to me. That's what I mean. Why learn 3 different meanings of pipe? I already have to learn too many meanings of pipe across multiple environments and languages. I do not need more pipe and map meanings within javascript.

I'm not sure I know the use case for all of this logical complexity. Is there a specific use-case you had in mind?

Split the array of elements to process. Set up a promise.all against a function that handles sync/async function calls against each chunk and accumulates an array of results. This isn't the end of the world for any of the practical use cases I can think of. The efficiency loss and memory consumption is miniscule even across hundreds of thousands of records. This is as concurrent as anything else - the event loop is still a mandatory part of the processing loop. You can even defer every 1000 records to the event loop. Javascript is syncronous so there is no concurrency without threading. I can't think of an IO or non-IO function that would create the issues described of not yielding. We used to have chunks of 1000000+ records that would freeze the event loop. We solved this with structured yields to the event loop to allow other processes to continue without dropping TCP packets etc.

If the results are objects, you're not even bloating memory too much. 800KB for 100,000 records seems fine for any practical use case.

I like the idea of an async generator to prevent over-pre-calculating the result set before it's needed but I couldn't justify pivoting to a set of new functions called pipe, map, etc that require a few too many logical leaps for your typical ECMAScript developers to understand.

What's the win here? It must be for some abuse of Javascript that should be ported to WASM. Or some other use-case that I've somehow not seen yet.

I was once speaking with a group of AAA game developers at Steam Dev Days discussing how to balance random interactions with gameplay. I think everyone with me had worked on larger teams and discussed complex solutions to create balance. My solution was much simpler and was similar to the random walk example in the article - each event of being grabbed by a zombie was generated based on a random chance that only initialized after X seconds from the last time you were grabbed.

The group of AAA devs laughed it off as not being feasible but our game had market validation (10m+ downloads). It made the game fun and eliminated the "I can't believe I got randomly grabbed twice within 5 seconds" type of interactions that make you want to quit.

We also observed a lot of panicked players jumping, twisting and doing everything but hitting 'shove' the 'V' key - especially streamers. So we added in support for being able to jump repeatedly/shake to get out of a grab.

Random is too random when it comes to gameplay enjoyment for sure.

This is a very good write-up on solutions to the random placement (2D) and random interaction over time (1D) problems without resorting to less savory solutions like I made.
