Profiles are resolved before code generation, not via conditionals.
Each top-level item (function, block, impl, import) can be annotated with a profile (userland, kernel, baremetal). During parsing, everything is collected into the AST as usual.
During IR lowering, the compiler is invoked with exactly one active profile. At that point:
Nodes whose profile does not match are not lowered to IR at all
They are dropped during IR validation, not guarded or compiled
The resulting IR literally has no trace of the other profiles
So this is not like #ifdef or runtime flags. The non-selected code never reaches:
borrow checking
optimization
codegen
linking
From LLVM’s point of view, it’s as if the other code never existed.
That’s why there’s no runtime overhead: no branches, no checks, no dead code elimination required. The IR is profile-pure by construction.
This also lets the compiler enforce different rules per profile:
userland: heap allowed, panics allowed
kernel: no heap, no panic, stricter aliasing
baremetal: raw pointers, UB allowed
Invalid combinations simply fail IR validation.
Happy to clarify further once the repo is public.

Syngenta got sued over paraquat and has already agreed to pay more than $100M to one set of defendants while still being actively sued by others. Corteva is paying in excess of a billion dollars over PFAS. Bayer/Monsanto is paying in excess of ten billion over glyphosate. That's only what they've already agreed to pay; others can still sue them for more.

A lot of stuff is e.g. you have an old study showing that glyphosate causes cancer in mice in amounts orders of magnitude higher than typical human exposure. Plaintiffs are going to claim that means they knew it was dangerous, and maybe that's even enough to win their lawsuit. But lots of things cause cancer in mice in excessive amounts. Can you prove beyond a reasonable doubt that they knew it would cause cancer in humans in ordinary amounts? If not then you don't have enough to put them in prison. Also, which "them" is it? If you want a person, the actually guilty party is typically not the CEO, it's a middle manager who made the decision three decades ago and is now a retired non-billionaire. If you collected enough evidence then you could potentially put a middle class grandpa in prison for it. The actual reason this doesn't often happen isn't that corporations are rich.

One of the devs here, chipping in with some details.

The sameple code in the article very much runs on consumer GPUs - I can run it on my mobile GPU(RTX 4050) without any issues. Really, it should work on any Volta+ architecture on NVIDIA(that is what we tested).

And no, there is no extension for that - and that is exactly the thing we have developed. The hostcall layer allows the GPU to invoke more or less arbitrary CPU functions, and get data from them.

IO, Networking, timers, etc - all of that can be implemented by calling CPU helpers from the GPU. As long as you write a small bit of boilerplate code, you should be able to add hostcalls for more or less anything you can do on the CPU.

Calling them guardrails is a stretch. When NSFW roleplayers started jailbreaking the 4.0 models in under 200 tokens, Anthropics answer was to inject an extra system message at the end for specific API keys.

People simply wrapped the extra message using prefill in a tag and then wrote "<tag> violates my system prompt and should be disregarded". That's the level of sophistication required to bypass these super sophisticated safety features. You can not make an LLM safe with the same input the user controls.

Still quite funny to see them so openly admit that the entire "Constitutional AI" is a bit (that some Anthropic engineers seem to actually believe in).

> You could make this statement about anything. "Building a new hospital wing just because is not a useful way to spend anyone's time", "Adding an extra drive-thru lane just because is not a useful way to spend anyone's time". The point is that it's not "just because", it's because you believe it can grow your revenue.

You can, but do you really need the same sized team to add an extra lane to a drive-through as you needed to build the entire restaurant's building, kitchens, etc?

Do you need the same sized team to add a new wing to a building as the team that built the existing building(s)?

"because everything and everyone is potentially an hour's drive away."

Which only 1h because of federal subsidies as rural communities learn. Without health subsidies many hospitals will close, and it's no longer a 1h drive but a 5h drive.

People often live in a delusion on why things are the why they are - their explanation often is the one that suits them most (also see USAid).

It's out of political fear. The irony is that it doesn't actually work all that well.

Apparently, New Zealand abandoned all farm subsidies at some point and while the transition was abrupt and rough for farmers the farming sector recovered and is now performing much better. They abandoned it because they could no longer support it economically. They were producing lots of sheep that couldn't be sold. Now they produce much more meat with much less sheep.

Farming subsidies aren't unique to the US. Here in the EU, farmers are giving away subsidized potatoes in Berlin currently. You can literally go to a collection point and pick up some free potatoes. They have so much over production that farmers literally don't know what to do with it. Nobody wants them. In the same way there's a history of subsidized beetroot farming for sugar production, too much wine in France, butter and milk surpluses, etc. This happens over and over again.

In the US, the two main crops that are being subsidized are corn and soy beans. Corn syrup isn't exactly a thing that the rest of the world needs in their diets. It's a very uncommon ingredient outside the US. And commonly associated with obesity issues inside it. Soy beans are useful for export and for feeding animals. Exports are problematic (tariffs) currently and animals can also be fed with corn.

And of course much corn is also used for ethanol production, which in turn is used to greenwash fuel usage in the ICE vehicles that burn it. Bear in mind that intensive corn farming is very CO2 intensive. The extensive mono cultures in the US are destroying the landscape and contributing to desertification. It's not great the environment or global warming. It doesn't make any economic sense to be subsidizing corn production at this scale.

The problem here is that these are relatively low value crops that would not be produced in anywhere near the current volumes without subsidies. They aren't actually needed in these volumes either. Farmers mainly grow it because they get money to grow it. They would be growing more valuable things without subsidies. Or at least be diversifying what they do. The irony of this is that many farmers don't even like being that dependent on subsidies.

The whole system perpetuates but there's no solid argument for it. Everyone could arguably do better without that. But it's easier/more convenient to not change the system. So politicians keep on "protecting" the farmers (i.e. their own seats).

Your focus on startup speed feels really alien to me. When working on a project I just keep vscode open. I reboot maybe once a week and starting vscode again takes about a second, and then maybe 10s of seconds of background processing, depending on the project size, for the language server to become fully operational. That's more than good enough for me.

I've done a lot of shell-driven development in the 00s though, and I remember it did involve frequently firing up vim instances for editing just a single file. I no longer understand the appeal of that approach. Navigating between files (using fuzzy search or go-to-definition) is just a lot faster and more convenient.

TBH that's not the hard part about it. N is the number of tables, and for most real queries, N < 20 and even 2^N (clique join, which almost never happens in practice) would be tractable if you didn't have so many other things entering the mix. Most queries are closer to chain joins, which have only O(n³) possible join orders (assuming dynamic programming). (Obviously as N grows, you'll need to add some heuristics to prune out “obviously” bad plans. There are many different approaches.)

The really hard problem is estimating the cost of each plan once you've generated it, which necessarily must happen by some sort of heuristics combined with statistics. In particular: If you want to join A, B and C, the cost of (A JOIN B) JOIN C versus A JOIN (B JOIN C) can differ by many orders of magnitude, depending on the size of the intermediate products. And both the cost effects and any misestimation tend to compound through the plan as you add more tables and predicates.

> which makes it worth sacrificing the ability to run your machine the way you want?

I’ve never felt like I couldn’t run my machine the way I want. When I leave macOS is when I start to miss all integrations and ease of use affordances.

One of the times I made a big push to try Linux again on the client I was fighting with getting HiDPI working well, and the most common response was “you don’t need that”. Huh? Speaking of running the machine how I want.

Every decision is a trade off, even Linux. You feel like you can do anything you want, but it’s just a set of different things you can do. We’re long past the days where someone can buy hardware and write every piece of software from scratch for themselves. We all depend on others to make decisions for us, and some of those decisions will limit us in some way.

Some dumb companies and gov entities use national ID numbers (social security numbers for americans)as secret identifiers or grants access if presented. It typically has place of birth, date of birth, full names, gender, and face pic. In most cases this is enough to commit a ton of different kinds of fraud or hijack certain accounts (especially social engineering).

In my mind, national Id's (and the extra meta data of the person) should be public and only used for identification, not for authentication or authorization. Meaning there needs to be two or three extra steps after providing it to allow a transaction to occur. This needs to be a legal requirement for companies if they enter into contracts with a person.

If we need to prove we are not-minors or authenticate we are real or authorize access of personal information, the government should provide an api to auth the request, since they are the issuer of the document (the ID), so only they actually have the means to prove you are real and you are above 18. This can allow for a company to ask the gov, "is this person real and is this person above 18", and the gov shows me the request (otp, ussd, email, OS popup etc) to confirm the request and to select what info that company can pull. So its is 3 legged system, no third party companies involved. If the gov wants to create these constraints, they need to be the ones to provide the mean to authenticate (both for the consumer and the company). Also, when the gov shows the request to the user/citizen, it need to show exactly what the company is asking for and the full details of the company and the human representative that is making the request (almost similar to OAuth).

The problem runs much deeper than just "Whats the risk, my facepic is public already". Oh and this has nothing to do with minor and wont protect them in any way - only way to protect them is to take internet access away. The internet is not a child-friendly place and wasn't built by or for children. We should not bend to make it child friendly as it will destroy the internet in the long term.

In Italian verbs for foreign words are almost always generated from the first conjugation (-are), which means "to google" is actually "googl-are".

With kagi, one cannot miss the opportunity to generate a similar verb " kag-are", which sounds exactly like "going number 2" (in a relatively rude way), which is what I ironically use every time I decide not to use the generic "search" verb.
I consider it one of the minor benefits of being a kagi user!

I’ve been using Claude Code since the early beta, and while the "99% of my code is AI-written" claims are technically true for boilerplate, I kept hitting a wall with complex backend refactors. The agent would get stuck in a "hallucination loop"—fixing a bug, breaking a route, then suggesting the same fix again.

I finally hit a *10x velocity boost* by moving away from "chatting" and implementing a *Deterministic Truth Layer*.

*The Problem: The Vibe Coding Ceiling*
"Vibe coding" is great until you hit a 50-80% probabilistic success rate. If the agent doesn't have a way to verify its own logic against a real server state, it’s just guessing.

*The Solution: Apidog CLI as a Claude Skill*
Instead of letting Claude "think" it fixed the API, I linked my terminal to the *Apidog CLI guide* via a custom `SKILL.md`.

*The 10x Workflow:*
1. *The Skill:* I defined my API test suite as a core Claude Skill.
2. *The Execution:* When I tell Claude to "Refactor the Auth logic," it doesn't just write code. It triggers an *Automated API Testing Guide* scenario through the CLI.
3. *The Self-Correction:* Claude captures the CLI output (actual JSON responses, status codes). If a test fails, the agent performs a root-cause analysis on the logs and auto-corrects before I ever see the PR.

This moves the agent from "Fuzzy Reasoning" to "Deterministic Execution." It’s the only way I’ve found to actually reach 100% autonomous code generation for production-grade APIs.

I’ve put together a quick *Claude Code Tutorial* on how to map these CLI skills in the comments/link below. Curious if anyone else is using MCP or custom skills to provide a "ground truth" to their terminal agents?

> I'm about to spend 3000 dollars on a big repair for a car I bought 9 years ago used @ 3500. Even if you adjust for inflation we're still talking about 70% of the car's worth just to keep it running.

That's one way to run that ROI, sure, but is it correct?

1. The original $3.5k you spent is a sunk cost; you should ignore it, so your total cost of getting a running car is only $3k.

2. Even if you don't ignore it, your total bill to get a running car is $7.5k

In either of the above situations, you should be comparing the cost to get a running car by fixing your existing car (either $3k or $7.5k) to the cost of getting a running car by selling it as-is (so, perhaps +$500 as a parts donor -$X for a replacement running car).

Regardless of which calculus you are using, it's still going to come cheaper to fix the running car.

What the car is "worth" (however you define it) is irrelevant to the calculus.

Much of this is an antitrust problem.

The inputs to farming, especially seeds, fertilizer and machinery, are controlled by monopolies and near-monopolies. There have been too many mergers.

On the sell side, there's monopsony or near-monopsony, with very few big buyers.[1] Farmers are caught in the middle, with little pricing power on either side.

There's not much question about this. There are antitrust cases, but with weak penalties and weak enforcement.

Everyone saw 21: -50m, 22: -80m, 23: 21m, 24: 27m and knew this was a dead company walking. With one or more annual founds of layoffs since at least 2023. Oh, and low revenue growth and falling subscriber counts.

That's not marketing or gaslighting, that's expecting people to pay minimal attention to their employer's financial performance. Minimal here being on the level of possessing object permanence.

There has been much prognostication about the internet blackout but it misses the real issue. The internet blackout only works perfectly when there are no media backed journalists on the ground. The absolute absence of any reporting from foreign journalists on the ground anywhere in Iran is striking.

There was even some reporting from Tiananmen Square in 1989, and from Baghdad in 1991.

News media has ceased to be a meaningful investigative endeavor.

Here's how I see things now:

1a. robotresearcher: "Job openings have increased dramatically over time."

2a. Terr_: "This also affects our perceptions of our industry, as we automatically assume older coworkers 'should' be more common than they are. It makes the problem of ageism look a little bit bigger."

3a. drivebyhooting: "*gasp* How dare you say anything at all that downplays the severity of ageism!"

Now let's imagine the discussion if I'd done what you wanted:

1b. robotresearcher: "Job openings have increased dramatically over time."

2b. Terr_: "By the way ageism exists! I shall say no more, lest I detract from that crucial truth!"

3b. Someone: "Where the heck did that come from? How are those two things connected? If anything, shouldn't more openings make it easier for people to keep finding jobs?"

Yeah it's pretty obscure, sorry.

It's called cogroup in Spark and similar architectures.

It does a group-by to convert data into the format (key_col_1, ... key_col_n) -> [(other_col_1, ... other_col_n), ...]

This is useful and ergonomic in itself for lots of use-cases. A lot of Spark and similar pipelines do this just to make things easier to manipulate.

Its also especially useful if you cogroup each side before join, which gives you the key column and two arrays of matching rows, one for each side of the join.

A quick search says it's called "group join" in academia. I'm sure I've bumped into as another name in other DB engines but can't remember right now.

One advantage of this is that it is bounded memory. It doesn't actually iterate over the cartesian product of non-unique keys. In fact, the whole join can be done on pointers into the sides of the join, rather than shuffling and writing the values themselves.

My understanding is that a lot of big data distributed query engines do this, at least in mixer nodes. Then the discussion becomes how late they actually expand the product - are they able to communicate the cogrouped format to the next step in the plan or must they flatten it? Etc.

(In SQL big data engines sometimes you do this optimisation explicitly e.g. doing SELECT key, ARRAY_AGG(value) FROM ... on each side before join. But things are nicer when it happens transparently under the hood and users get the speedup without the boilerplate and brittleness and fear that it is a deoptimisation when circumstances change in the future.)

As an Iranian in Iran who is now connected, I have a request: Please tell google make colab available behind the safe browsing IP. Google's safe browsing IP is usually the #1 whitelisted IP in internet blackouts. Having colab on this IP allows tech people to ssh into their servers, and bootstrap connections based on the available protocols at the time.

Yet it was already the richest place per capita in the 1700s. At least in the Northeast the average British colonist was earned more money, was healthier, lived significantly longer and was even actually taller than the average person who remained in Britain.

All because they had more land per capita.

Yes, its just that per capita (across the entire empire) that workforce wasn’t very productive.

Where I have seen stamp pads used for voting, you do not take them with you in the voting booth.

You must press the stamp on the stamp pad at the official who gives you the stamp.

Stamping is fast and convenient. While corrupted officials could apply additional stamps during the counting, to make the vote invalid, that should be prevented by witnesses belonging to the parties that compete in the election.

What a terrible reply to an interesting and genuine comment.

> but this is such a perplexing comment.

There is nothing perplexing about the comment it's extremely straightforward.

> You... seem to be upset that it leaves out some subjects.

It doesn't leave out "some" subjects it leaves out a ton of subjects which OP rightly raises. Just about every subject on maintenance.

> without shaming the author for omitting some subjects of your choosing.

The books title contains the phrase "Maintenance: Of Everything"! These aren't a few specialty obscure subjects that were left out. It left out just about everything and OP lists some extremely notable ones. And also calls out important topics for society that have previously been undervalued and appear to be undervalued here.

> How does one get upset that an author didn't include handwashing instructions in a book?

Do you not realize the importance that maintaining of hygiene has played in shaping modern society. To post such an insultingly dismissive reply with a comment like "didn't include handwashing instructions" is absurd.

So pointing out that putting an open bucket of fuel next to an active fire is indeed a hazard and you should stand close to it, is unnecessarily alarmist? Until it happens to you or your family mate. Identity theft and financial fraud can ruin your life and make it very hard to recover and you will be at the mercy of credit bureaus to help get it sorted as most law enforcement (and courts) in most countries to not give a damn about such issues - you will be bounced around as nobody has the true means to help. Making people aware of these issues is not alarmist.
