Well, I'm also fair certain that there are a lot of foreign intelligence services which, having infiltrated through DOGE, are currently leaving digital "gifts" throughout all of our systems.

So it's also about spying.

Not blaming those foreign agencies. I'd do the same thing if the shoe was on the other foot.

But congrats. Get your laughs in now. The US will be back. We'll have our day. Just takes time, patience and studied observation. We have a long memory.

Ok, but why stop here? You've effectively created a rotary potentiometer in one dimension, you could add two more dimensions like an analog thumbstick on a game controller. Do any controllers have a twistable thumbstick?

Also, like other commentors have stated - this could be a jack too, so you could have a jack knob analog stick.

BUT WHY STOP THERE?

You could mount it on a linear pot/slider.

BUT WHY STOP THERE?! (help me)

You could daisy chain pluggable rotary analog stick jack stacks...

> I disagree with other posts here, it is partially a balance between security and usability. You never know what service was implemented with possible security exploits and being able to throw every WAF rule on top of your service does keep it more secure. Its just that those same rulesets are super annoying when you have a securely implemented service which needs to discuss technical concepts.

I might be out of the loop here, but it seems to me that any WAF that's triggered when the string "/etc/hosts" is literally anywhere in the content of a requested resource, is pretty obviously broken.

> It usually isn't the interesting bit and it is a relatively recent quirk that everyone seems to care more about the framework compared to the thing you actually wanted to achieve. It's not a fun algorithm optimization, it's not a fun object modeling exercise, it's not some nichey math thing of note or whatever got them into coding in the first place.

I only read your comment after I posted mine, but my take is basically the same as yours: the GP thinks the IT learning-treadmill is fun and his dad doesn't.

It's not hard to see the real problem here.

I notice that the paper doesn't claim to eliminate all reasoning about undefined behavior for optimizations. For example:

int f() { int arr[3], i = 0; arr[3] = 5; return i; }

Optimizing this to "return 0" is relying on UB, because it's assuming that i wasn't laid out directly after arr in the stack frame. I believe this is what the paper calls "non-guardable UB".

I don't agree with the claim in the paper that their semantics offers a "flat memory model". A flat memory model would rule out the optimization above. Rather, the memory model still has the notion of object bounds; it's just simplified in some ways.

This is largely true in my experience. The industry regards software dev as the bottom of the pyramid. It's the job you start doing and you get promoted out of. I believe that's a huge contrast to other professions, in which you continue doing the same practice until you retire. The expectations are a lot more than just coding, as if coding wasn't hard enough. This all piles up and creates an overall miserable experience where the hardest part is NOT the technical part.

Did you read the warrant? They did not demand the judge tell them anything. They knew he was there and were waiting outside the courtroom to arrest him. The judge confronted them and was visibly upset. She directed the agents elsewhere and then immediately told Ruiz and his counsel to exit via a private hallway. The attorney prosecuting the case against Ruiz and his (alleged) victims were present in the court and confused when his case was never called, even though everyone was present in the court.

All carbon tax is inherently regressive but that's also trivially fixable. Make it revenue neutral and give every citizen a flat portion of the total collected revenue. Bam, it is now progressive, since on average richer people will spend more on fuel (and therefore the tax) even though it is likely a much smaller percentage of their spending.

Every single one of your ideas has problems that are solved by a carbon tax. Taxes are simple, they accomplish what you want, and they don't have loopholes. A carbon tax will _never_ have the unintended consequence of making emissions worse. Many of our current regulations, including the one I was responding to do exactly that because they actually cause people to buy larger trucks than they otherwise would with worse fuel efficiency.

A carbon tax might not on it's own be enough to solve the problem (especially if you set it to low), but no matter what level you set it, it will help. Thanks to unintended consequences, many of our current regulations are actively counter productive, while _also_ having negative economic and other costs.

Note that the comparator here is "exercise before bed compared with doing the same amount and intensity of exercise earlier in the day" -- NOT "exercise before bed compared with doing no exercise at all."

Actual RCT findings (e.g. [1]) find that exercise does induce beneficial changes in sleep, compared against not exercising at all.

for most things, college is a ripoff. medicine and law aside most of these courses could just be filled with just the books at a fraction of the cost.

Something harder like stem? ok so lets say your average person at 18 wants to learn to learn electrical engineering. they can either spend 10-20k per semester at a university for the next 4 years.

for the price of one semester, you can get yourself a all the books for your subject and...

mathacademy.com -> 500 bucks/yr

laptop -> 4000

oscillopscope -> $500-1000

power supply -> $400

prusa core one 3d printer + mms (makign enclosures etc) -> $1800

various other smaller stuff (multimeter, wires, components) (1000-2000)

That still leaves plenty of cash to just pay an engineer or tutor by the hour to give you personalized attention and answer any questions you might have.

Locas.dev – AI Location Suitability Analyzer for Real Estate and Busines
by azharmo | 2025-04-25 17:49:13+00:00
I recently launched https://locas.dev, a side project that uses AI to answer one of the most critical questions in real estate and business: “Is this location a good fit for what I want to do?”

What It Does Locas.dev takes a single input – a natural language question like:

“Is Downtown Chicago a good place to buy land?”

“Would Miami Beach be a good spot for opening a restaurant?”

Then it fetches real-world geo-tagged data like school ratings, hospitals, police stations, restaurants, air quality, transit nodes, green space, and even pollen levels — processes it using a custom-built LLM + rules engine — and responds with a structured, explainable breakdown.

Each answer includes:

Ratings across dimensions like services, amenities, transport, environment, and competition

Google Maps links to nearby landmarks

Human-readable insights with pros and cons

A clear summary and final verdict

Tech Stack Built with Python, LangChain, and a custom vector lookup engine

LLM-driven reasoning with deterministic safety layers

Google Maps, OpenStreetMap, and public datasets for grounding

Fully stateless – just one GET request per analysis

Why I Built It As someone working in AI and education, I constantly run into the challenge of selecting the “right place” for programs, centers, or even partnerships. Existing solutions are either too manual, map-based, or lack narrative reasoning. I wanted something that thinks about a location the way a human researcher or consultant would — but on-demand, in seconds.

Try It There are a few public demos on the homepage — feel free to test it with your own questions.

→ https://locas.dev

Would love feedback from fellow HNers! I'm especially curious about:

Potential use cases you see

What features you'd want next (e.g., scoring your own address, neighborhood comparisons, investment suggestions)

Integrations (Slack, Notion, etc.)

Thanks for reading! – Azhar

The specific regulation is here:

https://www.ecfr.gov/current/title-49/part-571/section-571.1...

Nor practical but an analog system could probably meet the standard.

---

Rearview image means a visual image, detected by means of a single source, of the area directly behind a vehicle that is provided in a single location to the vehicle operator and by means of indirect vision.

Rear visibility system means the set of devices or components which together perform the function of producing the rearview image as required under this standard.

5.5 just says it needs to meet certain testing standards, start displaying within 2 seconds of backing up, and stop displaying when driving forward.

when topics are too political usually flame wars abound and moderators can choose to flag/derank a submission to avoid the comments section going wild or just close comments altogether in extreme cases

all i can find on doing research is if a thread has more comments than upvotes that might be what flags it as flamewar candidate (but seems mostly is manually reviewed by moderators, not fully-automated) https://news.ycombinator.com/item?id=39790881 https://news.ycombinator.com/item?id=39231821

ARM NEON does have sum, min, and max reductions (and/or reductions can just be min/max if all bits in elements are the same), along with pairwise ops. RVV has sum,min,max,and,or,xor reductions. x86 has psadbw which sums windows of eight 8-bit ints, and various instructions for some pairwise horizontal stuff.

But in general building code around reductions isn't really a thing you'd ideally do; they're necessarily gonna have higher latency / lower throughput / take more silicon compared to avoiding them where possible, best to leave reducing to a single element to the loop tail.

There's an adage I heard during my time in game dev that went something like "gamers will exploit the fun out of a game if you let them." The idea is that people presumably play videos games to have fun, however, if given the opportunity, most players will take paths of least resistance, even if they make the game boring.

I see the same risk when AI is understood to be a learning tool. Sure, it can absolutely be a tool for learning, but it does take some will power to intentionally learn if it is solving short-term problems.

That temptation is enormously amplified if AI is used as a teaching tool in grade school! School is sometimes boring, and it can be challenging for a teen to push through a problem-set or essay that they are uninterested in. If an AI will get them a passing grade today, how can they resist?

These problems with AI in schools exist today, and they seem destined to become worse: https://www.whitehouse.gov/presidential-actions/2025/04/adva...

So the prompts that are sent to the planner vs executor are completely distinct. We allow complete customization of the planner LLM with all major providers (Anthropic, OpenAI, Google AI Studio, Google Vertex AI, AWS Bedrock, OpenAI compatible). The executor LLM on the other hand has to fit very specific criteria, so we only support the Moondream model right now. For a model to act as the executor it needs to be able to specific specific pixel coordinates (only a few models support this, for example OpenAI/Anthropic computer use, Molmo, Moondream, and some others). We like Moondream because its super tiny and fast (2B). This means as long as we still have a "smart" planner LLM we can have very fast/cheap execution and precise UI interaction.

I am going to be downvoted to oblivion but sanctuary cities for what you are saying is like a monkey patch in code. It "works" for now but it's not a long-term viable solution. A person breaking the law and be fine to be a criminal to be in a country is already the wrong mindset. And these persons are only at step 1 in a life in the US. What happens when life will be tough later are they now magically going to stop all criminal solutions? Their solution to be in the US was already to break the law.

Thankfully there are already laws to protect people being persecuted, in danger, people needing asylum, etc... We need even better laws in these areas and improvements in witness protection laws for a part of your example. But again sanctuary cities "work" for now but it is not a long-term solution. Beyond attracting criminals, it also creates a weird lawful oxymoron at the opposite of the rule of the law. (And again, there are things like asylum, etc...)

> There’s complications, of course. The federal government is fine with you selling combustion-powered kit cars as long as they have no engine or transmission. That’s easy for me because motorcycle engines almost always have gearboxes attached to them—both can be installed as a single unit. It’s hard for me because, as far as I can tell, the federal government has never defined what portion of an EV’s drivetrain has to be left out for it to be considered a kit. If you’re wondering why there are basically no electric kit cars, well, that’s probably a big part of it.

> Could you sell an EV with an electric motor and a battery, but no inverter? How about just a battery? That has seemingly never been spelled out. I have sent the NHTSA a letter requesting it clarifies this. I’ve also joined SEMA to get more legal advice on this front.

I wonder what the specific wording of the regulation is and if it even would cover EVs.

And how exactly does this company's product prevent such heinous attacks? A few extra guardrail prompts that the model creators hadn't thought of?

Anyway, how does the AI know how to make a bomb to begin with? Is it really smart enough to synthesize that out of knowledge from physics and chemistry texts? If so, that seems the bigger deal to me. And if not, then why not filter the input?

Depends, Azure definitely has the integrations needed for modern debugging.

With application insights and event tracing, that can be event plugged and debugged postmortem on Visual Studio.

Java world has similar ways with JMX, Visual VM and JFR.

Another great one on part with these two for distributed computing are Erlang based systems.

Finally we have language agnostic ways to do similar workflows based on open telemetry, even if code reload is not part of it.

Step debugging is the hello world version of how to use a debugger.

I do. I want people to work a normal day. The alternative is they run into a wall of fatigue at the worst times, and call out sick.

I can plan a project around five 8 hour days a week. I can't plan around 60+ hours one week, and (unknown) hours some future week.

Progress is not evenly distributed, nor are all forms of progress beneficial.

In my mind, it is exactly because of the areas of regression that other areas of progress are problematic if we don’t place enough focus on solving the new problems such progress creates.

e.g. many of the worst aspects of modern social media discourse boil down to people with an extremely limited understanding of complex problems believing in overly simplistic solutions and forming strong world views based on that lack of understanding.

Much of the technological progress recently involves abstraction on top of abstraction on top of abstraction making extremely complex things appear simple. The further down this road we go, the further the technology moves the average person out of contact with the underlying reality.

Push a button and shoes show up at your door. Nevermind the thousands or hundreds of thousands of people involved in making that happen or the many harms that occur along the way ranging from ecosystem destruction to child labor.

I don’t see the concerns I have about certain forms of progress as having any bearing on the areas of obvious regression. I’d even argue that some of the progress has directly caused that regression. The law of unintended consequences and all that.

Except if you understand they were being misleading, and you understand why, you also understand Covid was a real problem and that there were serious infrastructure and logistics problems that had to be dealt with. You get angry with the government for fumbling the effort, but you still get vaccinated. That doesn't justify believing Fauci and Biden cooked up Covid in a lab or that the vaccines were spiked with microchips or that masks give you brain cancer or half the stuff antivaxxers actually wound up claiming.

People literally formed resistance organizations and were warning of a global fascist takeover, we were entering an eternal police state in which the unvaccinated would become a slave underclass and if you didn't have your vaccine card you would get shot dead in the street.

All of it went far beyond simple mistrust in the government's PR.

I would hope it’s not.

I would like for cops to be more humane in arresting people and stop going to place of work to grab people in front of their coworkers. But this seems like just as rude when they go to a “regular” person’s office in the middle of the day and arrest them.

The argument is that if they notify the accused beforehand they may flee. But I don’t buy this as many people will likely turn themselves in if notified. I’m guessing an ai could predict with 99% accuracy people who will self surrender and save everyone embarrassment (and money).

The way I read it is that US citizens have a right to not be murdered or assaulted by people who enter the country illegally.

So it seems like a Judge would have an obligation to prevent someone accused of being in the country illegally and accused of a violent crime to not leave the courthouse and instead turn that person over to the federal authorities who are outside the court waiting for the proceedings to finish.

150 mile range makes it close to useless. As soon as you take it on a highway, the range will likely drop by half. Which means you can only do a round trip of 37 miles before you have to charge.

Even a very aerodynamic Model 3 loses half of range at highway speeds.

Comments like these are rooted in selection bias (willful or otherwise).

You're never gonna see trucks being used at the grocery store because people who are in the process of using said truck for truck stuff aren't usually stopping at the grocery store as they do it, and this is before you adjust for what kind of grocery stores HN shops at vs the kind that people who use the crap out of their trucks shop at. If you live the median "suburb to office and back" life you'll never see trucks doing anything. You need to be on the road and not in a cube during hours when "things" get done to see that. And the people who do things with their trucks mostly don't live and cross paths with the people who don't.

I could use the exact same faulty logic you're using here with slightly different parameters and come up with the conclusion that cars don't need a second row of seating.

And before anyone projects anything stupid at me, I own a minivan.

interesting, will check out yours i'm mostly interested on these dynamic routers so I can mix local and API based depending on needs, i cannot run some models locally but most of the tasks don't even require such power (on building ai agentic systems)

there's also https://github.com/lm-sys/RouteLLM

and other similar

I guess your system is not as open-ended task oriented so you can just build workflows deciding which model to use at each step, these routing mechanisms are more useful for open-ended tasks that dont fit on a workflow so well (maybe?)

This over-simplifies our federal system to the point of uselessness.

The Federal Government is responsible for immigration. It's their job to set policies and adjudicate immigration issues.

Local and State Law Enforcement are not responsible for -- and indeed it is outside of their powers to enforce immigration laws.

Supreme Court precedent is that states cannot be compelled by Congress to enforce Immigration law (see: Printz v. United States).

So, what you have in this situation are the fact that States and the Federal Government have opposing interests: The States need to be able to enforce their laws without their people feeling like they can't tell the police when there's a crime, and the current federal policy is to deport all undocumented immigrants, no matter why they're here or whether they are allowed to be here while their status is adjudicated.

I said the process started with JFK. Trump moved the needle a lot in the last 8 years, too, so it clearly wasn't finished then either and probably still hasn't finished, because parties are messy dynamic things that change all the time.

This line of thinking only works if you consider illegal immigrants as people of which a certain side does not and is actively arguing that the bill of rights only applies to citizens.

Basically, if you view illegal immigrants as the end of the world, then any deferral of their deportation is equally as bad. There is no room for discussion on this topic, being "illegal" is a cardinal sin and must be punished at all costs.
