The word "is", maps to the logical "equals" operator. I agree with the example, but I don't agree it is relevant. There is no implies operator.

The statement "Math is Language", where A is Math and B is Language, maps to the logical assertion: "A = B".

If we are going to really be kinda twisty and non-standard, we could interpret the english "is" to be "is an equivalence class of". Which would map to your example pretty well: language is indeed an equivalence class of math, but math is not an equivalence class of language. Though, nobody is talking about implies operator or equivalence class here.. It's a "is" relationship, logical *equals*

If anyone is interested in the difference between "AI slop" and something with a couple thousand credits into it, here's my #soundseasons entry (I don't expect to place; the end needs work I didn't have the energy for (and I mean even if I did...)):

# Original record scratch contest-style song https://suno.com/s/8MvZmfkDPIPmKLtm

And this is a good example how the "magic" is lost in a cover of that same contest entry with no attempt to curate:

# v4.5 cover https://suno.com/s/KyCZZNn6PpL4JHbO

Here's another one I put a bit of time into, but with a much simpler structure. What I appreciated about the original were the emotions it stirred up when the notes came together just-so:

# Original ambient synth https://suno.com/s/JtmmbdA2VtgO4drK

New cover, pretty decent but it lost what I liked the most (haven't had great luck with v4.5 remasters yet, but I do a lot of weird things):

# v4.5 cover https://suno.com/s/Gi8wy1QjUaHmYNKy

# Original piano piece https://suno.com/s/yj8rHRRgJEWD83GY

# v4.5 remaster https://suno.com/s/Xx5Y5SNl1MdDrLsO

When you ignore the stuff that humans shouldn't get credit for - e.g. I didn't "make" this song, or play any part in its "production", but I did "curate" it - there's still something left to give credit for, right? It's basically like a DJ digging through a mysterious crate of records.

There's an ideological assertion when automation happens: the workers will retrain and be better off.

If it was true, Youngstown Ohio and Flint Michigan would be jewels of the Midwest - bustling metropolises of highly skilled retrained workers in wondrous utopias. You'd have AI unicorns popping out of Huntington and Wheeling, West Virginia.

Whether you count number of bankruptcies, overall mortality rate, number of offspring, percentage that own versus rent... The fervent assertion that going from a union job to hustling for say Postmates, is somehow the rising tide lifting all boats is baseless.

Doesn't matter though. It's ideologically, not materially based so evidence is irrelevant.

There Are state interventionist ways to make it work. China moved from agrarian to industrial. South Korea, Taiwan Japan.... The difference is they don't have this pentacostal snake handling level blind faith in the free market where they go around like Peter Popof preaching Hayek and Rothbard like it's sacred scripture.

Put simply, GPT has no information about its internals. There is no method for introspection like you might infer from human reasoning abilities.

Expecting anything but an hallucination in this instance is wishful thinking. And in any case, the risk of hallucination more generally means you should really vet information further than an LLM before spreading that information about.

The game model might involve 20ms time slices. The frame rate is simply the best available visualisation of the "action" that the machine can manage.

So, you have your game model, input and output. Output needs to be good enough to convince you that you are in control and immersive enough to keep you engaged and input needs to be responsive enough to feel that you are in control. The model needs to keep track of and co-ordinate everything.

I'm old enough to still own a Commodore 64 and before that I played games and wrote some shit ones on ZX 80, 81 and Speccies. I typed in a lot of DATA statements back in the day (40 odd years ago)!

When you pare back a game to the bare basics - run it on a box with KB to deal with instead of GB - you quite quickly get to understand constraints.

Things are now way more complicated. You have to decide whether to use the CPU or the GPU for each task.

i have always maintained a slightly underweight body, well into my 30s, despite limited exercise and unrestricted eating.

i personally know many people who struggle immensely, despite eating far less than me.

for me, it takes exactly 0 effort to remain thin. zero. i literally don't even think about it. other people count every single calorie they eat, exercise religiously, take weight loss medication, and still have trouble managing their weight.

but hunger is a primal thing - some people are far hungrier far more often than other people, for many reasons - and yes, it takes energy to resist hunger.

money and free time aren't required, no, but it definitely helps your odds.

Sorry about that. It's just me working on it, and so far my personal tenet is that the product itself is the top priority, and all else including marketing comes second, so none of the website/youtube/etc are as good as I'd like. Possibly I'll soon have money to hire help with some of that, or I'll get the product to a place where I'm happy enough to work more on marketing myself.

What stops highway robbery today?

Logistics. Unless you know exactly what's in the cargo, it's probably not wortht he effort because you might get a load of toilet paper. Also getting your ill-gotten gains away from the scene is going to be a lot of work, how much stuff are you going to be able to unload before the cops show up and how many vehicles will you need to get it? You'd be better off stealing the truck itself.

New Zealand doesn't have inland waterways the way the US does so barges don't seem sufficient. They did actually get a fancy self-propelled barge for use transporting minerals on the West Coast of the South Island last year and it got pushed aground by a storm in its first couple weeks of service. It's been sitting in port in Nelson ever since being refloated.

There is no problem to solve because there is no rug to pull out. Redis are not owed anything and no one stole anything from them.

When I try to make a business hosting copies of an http server, I am not pulling the rug out from under nginx who actually wrote the http server.

And when AWS does that better and than me, they are not pulling any rug out from under me, or at least not in any way that is special to any of the software involved, just plain old bigger businesses vs little businesses, no different than say Safelite vs Joe the Glass Guy.

When I returned to college ~15 years ago, my main laptop was a ThinkPad T60 running some flavor of Debian. I spent a lot of time with a full-screen terminal open in some sort of green-on-black color scheme.

On several occasions some complete stranger would interrupt me - usually with a shoulder tap - and demand to know what I was doing hacking in the library/student union/etc. Never happened in the engineering buildings, though.

Cool project!

I run tech for a reverse logistics business buying overstock from Costco/Target/Walmart and we’re building a similar system for recognizing and pricing incoming inventory. I sent an email a few days ago to see if you might be open to chatting.

The Romans were actually quite smart after Cannae; they had lost a bunch of pitched battles, so they decided to shadow Hannibal's army to make his foraging logistics much more complicated (and forcing him to stay close to Southern Italy where he could easily resupply). The logistics of attacking Rome were therefore challenging at best, and the Romans used this as a delaying tactic to score wins on other fronts (since they enjoyed an overall manpower advantage).

We’re assuming the defendant is without means. If I were in jail, I’d probably spend a decent amount of my spare time filing this sort of thing. If it were hopeless, I could also see myself just trolling. What else will I spend my money on?

I take this not as people being dumb, but as a clear conflict of interest: people want to be able to rate the logistics provider separately from the product, but marketplaces don't want to give people the option to do that — as that would reveal that the marketplace will sometimes decide to use "the known-shitty provider" for some orders. (And make no mistake, the marketplace knows that that provider is awful!)

The optimal control framework Casadi has had the ability to compute sparse jacobians and hessians for a long time (maybe a decade?), which come up all the time in trajectory optimization.This not only provides massive speed ups in both the differentiation and linear solver time, but also greatly reduces the memory requirements. If this catches on in machine learning, it will be interesting to see if we can finally move past first order optimization methods.

It creates weird scenarios in other cases too. I asked it to do generate text to speech audio in a wrestler style voice, which ChatGPT doesn’t do.

But… it lied, and produced empty audio clips and weird pictures with text.

Then it:

- said there was a technical problem - said it could not create audio - created weird 1980s computer voice style audio - claimed I was violating a content party.

I said “stop wasting my time” and it spewed a ridiculous apology. I kept asking and it referred me to various websites. I’ve never inadvertently triggered such a wacky hallucination, and I can see how a vulnerable oersom could be troubled by it.

I'd rather we just did an increment of 3 rating. 1. Bad 2. Fine 3. Great

2 and 4 are irrelevant and/or a wild guess or user defined/specific.

Most of the time our rating systems devolve into roughly this state anyways.

E.g.

5 is excellent 4.x is fine <4 is problematic

And then there's a sub domain of the area between 4 and 5 where a 4.1 is questionable, 4.5 is fine and 4.7+ is excellent

In the end, it's just 3 parts nested within 3 parts nested within 3 parts nested within....

Let's just do 3 stars (no decimal) and call it a day

That's the rule, but AFAICT Wal-Mart is the exception to the rule. They don't train anybody without years of loyalty to the company, I don't think they have obligations. It's the dream job for most truckers from what I hear, and once you get in you don't leave. Wal-Mart pays a solid 6 figures with great home time. You can make more than that with your own truck, but it's hard.

I'm sure it's like any job -- everything else can be great, but if you get stuck with a bad boss it can make you absolutely miserable and drive you out.

There's some pretty foreseeable stuff just considering the existing attention capitalism business model of big tech we all know and loathe. Eventually OpenAI is going to have to make money, and blending ads into answers will be an obvious way. Next step will be maximizing eyeball time on those ads by any means necessary, including all the engagement baiting techniques Meta and other social media companies have already pioneered.

My previous company, Parallel Systems is working on this. The solution looks a lot like trucks on rail: individual locomotion, so you get the flexibility of trucking, but the energy efficiency and automation ease of rail. With modern braking, you can stop a Parallel vehicle about as fast as a truck. There's a ton of rail that's underutilized, particularly in Metro areas, so you almost get a fresh highway for free. Vehicles can platoon or separate at will.

This effectively exists already in the form of paying third-party for a maintenance contract. Actually bumping the version number and repushing an app is the trivial part of being forced to do yearly (or w/e) updates - there’s a bunch of grunt work that can’t be automated in a trivial way - bumping your API targets, fixing anything that breaks from that, updating your build pipelines, fixing anything that breaks from updating your build pipelines, etc.
by wahern | 2025-05-02 23:54:46+00:00
They can all be changed, but then the capital costs for rail infrastructure would balloon and diminish the 3-5x cost advantage rail has over trucking. The modern rail business is structured (physically and, especially, financially) to squeeze every last cent out of existing infrastructure with minimal investment. I doubt that will change significantly anytime soon. The public road infrastructure subsidizes trucking (even after factoring in use and fuel taxes), and perhaps more importantly trucking companies don't have to contend with legal hurdles like land acquisition--the government handles that. (Land acquisition delays have been the biggest barrier for CAHSR.)

That's very interesting, thank you for typing it up!

> Express based project

Ahh, so you use a monolith in a lambda. I should have gone this route. I was concerned about package size (due to lambda limits) and so went the "one function per endpoint" route instead. That seemed to be what AWS was saying you should do but it really screws you in a number of ways, size is the only place where it really helps. Provisioned lambdas, for example, are so much better for a monolith.

Did you not have size issues putting all the code in 1 package? That was a real limit I hit when I was (naively) packaging all my code for every endpoint instead of just the handler and the code it needed. I'd be nervous of pushing up against the limit. I guess the escape hatch is moving to a docker container on lambda since that gives you 10GB.

> The only thing I kind of dislike is decommissioning of older nodejs runtimes so they aren't available at all for new Lambdas anymore.

Yep, I've been burned by this and forced to update.

One more question, how do you handle local development? Do you just run Express directly? That's one reason I've leaned into the serverless frameworks out there. My function-per-endpoint setup doesn't have any default scaffolding, running via lambda is the only way to run the code (or one of the project that tries to replicate lambda locally). SST has been the best on this front since you deploy your dev environment like normal (spin up real queues, etc) but the lambdas are just proxying the request to the code running locally on your computer. This has resulted in the least "gotchas" when it comes time to deploy (though arch differences are always a blast).

I think flame graphs are perfect for what they do, compressing multi dimensional data down into fewer dimensions.

It makes it a lot easier to visualise at a glance, and sometimes an issue is obvious from the flame graph.

But you're right, for complex issues I find I need to dig deeper than that and view everything linearly.

They're just nice for glaring issues, it's like a mini dashboard almost.

I haven't so far. I’ve preferred the new way:

With RSCs, I’d have code scattered throughout components that would hit APIs to get data.

With Rails + Inertia, that code is all in a Rails controller - usually with a serializer.

I’m still getting used to using InertiaRails.optional there which is what’s needed for a Suspense like experience w/Inertia. Having everything in controllers again is nice.
Open-source database of vendor compliance information (SoC 2/ISO 27001)
by gearnode | 2025-05-02 23:58:16+00:00
Most compliance companies are spending hours hunting down the same informations, SOC 2 and ISO 27001 certificates, subprocessor lists, BAAs, terms of service, and so on.

To make that process easier, I’ve started putting together a maintained, open-source database of vendor compliance details. Right now, the database includes: - Links to vendor compliance certifications (SOC 2, ISO 27001, HIPAA, etc.) - Legal entity names and headquarters addresses - Subprocessor list URLs (which are often buried) - BAA availability indicators - Security/trust center pages

This is an early version, lots of vendors are still missing, but I’m planning to keep expanding and improving it.

If you find it useful or have ideas on what would make it better, I’d love your feedback.

And the worst part is that it goes both ways.

Brain expects movement (from visual stimuli) and doesn't feel any movement? Nausea. (VR sickness)

Brain expects stability (from visual stimuli) and feels movement? Nausea. (Sea sickness).

This is why when you're sea sick they tell you to watch the horizon, because if you watch the horizon, you can tell that the horizon is going up and down and your brain can correlate that to the motion.

Well, that's always what LLM-based AI has been. It can be incredibly convincing but the bottom line is it's just flavoring past text patterns, billions of them it's been "trained" on, which is more accurately described as compressed efficiently onto latent space. Like if someone lived for 10,000 years engaging in small talk at the bar, has heard it all, and just kind of mindlessly and intuitively replied with something that sounds plausible for every situation.

Sam Altman is the real sycophant in this situation. GPT is patronizing. Listening to Sam go off on tangent about science fiction scenarios that are just around the corner... I don't know how more people don't see through it.

I kind of get the feeling the people who have to work him every day got sick of his nonsense and just did what he asked for. Targeting the self-help crowd, drive engagement, flatter users, "create the next paradigm of emotionally-enabled humans of perfect agency" or whatever the fuck it he was popping off about to try to motivate the team to compete better with Anthropic.

He clearly isn't very smart. He clearly is product of nepotism. And clearly, LLM "AI" is an overhyped, overwrought version of 20 questions artificial intelligence enabled by mass data scale and NVidia video game graphics. it's been 4 years now of this and AI still tells me the most obviously wrong nonsense every day.

It's not limited to Soviet missions. My high school physics teacher worked at JPL on the Mars Climate Orbiter in the 90s. His entire NASA career was in development of it, and after 10 months of travel following successful launch, the thing exploded in the atmosphere without ever reaching the surface because the team at JPL used metric while Lockheed Martin used imperial. He was so spiritually broken by the experience that he quit and became a high school physics teacher. Great teacher, but to have your life's work go up in smoke like that is brutal.

Rail freight's share of shipping has been on a steep decline for decades in Europe:

> Freight rail’s modal share has been in decline across Europe, both in terms of market share and the profitability of major operators. In France for instance, modal share declined by 50 percent, from around 30 percent in the 1980s to 15 percent today. By contrast, road transport has been steadily increasing. In 1980, less than 50 percent of goods were transported by road. This rose to more than 75 percent by 2018.

https://www.mckinsey.com/industries/infrastructure/our-insig...

By contrast, for most of that same period (1980-today) rail freight was growing its share in the US, though in the past decade or so growth has favored trucking.
