The section on feedback control reminded me of procedural animation where you don't calculate the velocities and positions directly; instead the animation is a consequence of constraints and a target.

I took your PD controller concept and added anticipation using two targets: the original mouse target, and an "anticipation" target set proportionally based on the distance from the point to the main target[1].

This also made me think of Jelly Car and the amazing simulations they did using rigid frames for soft bodies, called Shape Matching[2]. Instead of simulating the soft body physics directly, they used a frame, springs, and "gas" to constrain points, which moved towards targets fixed to the frame.

As a designer I can say that the truth is that customers expect things to get remade and updated and if you wait too long the stale aesthetic begins driving away new AND existing users who want to try out shiny new things. Nice hallucination though blaming it on designers, the folks with no decision making abilties who are often blocked by PMs and devs.

I think a hurdle one has to make to adopt Emacs is to stop expecting things to work as you might have come to expect them from other programmes. Sometimes this is for historical reasons, but the main reason is that Emacs just has it's own logic, which may seem counterintuitive at first but often has very good reasons behind it. Try to persist past through that final 10% and you may find there are reasons why they're as they are. And when you need help use the channels out there...

The vast majority of consumers want their camera to take pictures of people that “look good” to the human eye; the other uses are niche.

But that said, I’m actually surprised that astrophotographers are so interested in calibrating stars to the human eye. The article shows through a number of examples (IR, hydrogen emission line) that the human eye is a very poor instrument for viewing the “true” color of stars. Most astronomical photographs use false colors (check the captions on the NASA archives) to show more than what the eye can see, to great effect.

> With 44GB of SRAM per Cerebras chip, you'd need 45 chips chained together. $3m per chip. $135m total to run this.

That on-chip SRAM memory is purely temporary working memory and does need to hold the entire model weights. The Cerebras chip works on a sparse weights representation, streams non-zero off their external memory server and the cores work in a transport-triggered dataflow manner.

No, you have proven my point. There is no strong evidence and IT WILL NEVER BE cause it's like trying to make a new study for a drug that has its patent expired. Are you willing to sponsor studies with your own money? Cause nobody else will.

Unfortunately, we are stuck with the little evidence there is from the last century when it was the heyday of balneological applications. However, these little studies we have, even with few patients is better than nothing and certainly there is also not enough proof that these patients have been harmed, if doing radon therapy according to modern standards of exposure.

As mentioned before: the linear extrapolation of the risk from high doses of radiation to low doses assumed by the LNT model greatly overestimates the risk of harm, and ignores the potential benefits. Low doses of radiation have been found to stimulate growth (Stebbing 1982), DNA repair (Kondo 1998a and 1998b), antioxidant action (Feinendegen 1987; Pollycove 1998), and immune response (Liu et al. 1987). Other studies have shown that cancer rates actually decrease in populations exposed to low levels of radiation beyond normal background radiation (Bogan 1998; Cohen 1995; Dissanayake 2005; Hattori 1997; Kondo 1993; Mifune 1992). The overestimation of risk by the LNT model is considered important by hormesis advocates, because its cautious perspective prevents patients from receiving low-level ionizing radiation treatments, such as radon, which might help them. Moreover, if radon levels were held to the standards mandated by the EPA and other agencies following the LNT model, the costs of residential radon abatement would be extraordinarily high (Macklis and Beresford 1991; Thomas and Goldsmith 1995).

Avoiding marketing surveillance is both reasonable and increasingly sought after; consider how many mainstream services now offer paid options just to reduce data collection by advertisers.

Modern surveillance states operate on the premise that every individual, out of billions worldwide, could become a potential threat. To manage this, governments have developed and deployed mass surveillance technologies that far exceed the scope of traditional law enforcement. This environment results in routine circumvention—both legal and extra-legal—of civil liberties and privacy protections, such as the 4th amendment, in the name of national security.

We saw this play out dramatically with the Snowden revelations, which exposed systemic, warrantless collection of communications by agencies such as the NSA. Surveillance is not conducted only for clear national emergencies. It is often routine, preemptive, and opportunistic—and the scale is massive, not targeted only at 'bad actors'.

This reality creates a profound power imbalance. Those who control surveillance infrastructure possess the ability—and in some cases, the legal clearance—to act against individuals or groups for reasons ranging from strategic interests to petty personal motives. There have been numerous documented cases of abuse of surveillance powers by insiders seeking to settle personal scores and, internationally, governments using this capability to quash dissent (for example, China’s censorship and criminalization of government criticism)

Once the technology and precedent for ubiquitous surveillance are in place, the distinction between legitimate and illegitimate use blurs dangerously. The potential for abuse is inherent, especially when oversight is weak or accountability is lacking, which is everywhere.

While companies like Google pose significant privacy concerns and “opting out” of their ecosystems is prudent for reducing commercial data exploitation, the larger threat comes from the normalization of universal, warrantless surveillance by state actors.

Full custom. That is, not only is it our own DSP architechture and own instruction set, but the firmware running on it.

Normally we'd have the firmware loaded from elsewhere on system boot at the cost of a few hundred miliseconds, but for the current project we need a much larger firmware and the bootup time is prohibitive. So we've ended up with a three-way partition of functionality. A "standard library" of mature functions in ROM, an application-specific set of medium maturity functions in OTP (one time programmable) which can be changed without needing an expensive metal layer respin, and finally the actual application in RAM.

For the same reason that I didn't replace my linux at home and at works by windows: because they have different strengths.

Windows has for it:

- the gazillion software, free or crazily expensive, that do not exist on linux

- the hardware compatibility, whatever is built, it is with windows on mind

- the office file formats that are the de facto standart

- the software installation model that is very crap but infinitely better than on linux

- the OS upgrade path also has it's issue but still much better than on linux

Of course linux has its strength also, and you can find it better in some cases on the points I listed

> iptables was already doing heavy lifting for other subsystems inside our environment, and with each VM adding or removing its own set of rules, things got messy fast, and extremely flakey

We saw the same thing at Vercel. Back when we were still doing docker-as-a-service we used k8s for both internal services as well as user deployments. The latter lead to master deadlocks and all sorts of SRE nightmares (literally).

So I was tasked to write a service scheduler from scratch that replaced k8s. When it got to the manhandling of IP address allocations, deep into the rabbit hole, we had already written our own redis-backed DHCP implementation and needed to insert those IPs into the firewall tables ourselves, since Docker couldn't really do much at all concurrently.

Iptables was VERY fragile. Aside from the fact it didn't even have a stable programmatic interface, it was also a race condition nightmare, rules were strictly ordered, had no composition or destruction-free system (name spacing, layering, etc), and was just all around the worst tool for the job.

Unfortunately not much else existed at the time, and given that we didn't have time to spend on implementing our own kernel modules for this system, and that Docker itself had a slew of ridiculous behavior, we ended up scratching the project.

Learned a lot though! We were almost done, until we weren't :)

Yeah, given that after the first move attempt, the only thing left in the original folder was subfolders, (meaning files had been "moved"), the only thing I can think is that "Shell move" must have seen that the target folder was outside of the project folder, so instead of moving them, it deleted them, because "hey at least that's half way to the goal state".
by dfedbeef | 2025-07-23 14:35:33+00:00
The reliable way to do this (I found) is check the kernel source tree first. The supported pro sound cards are, typically, kind of old. Because FOSS developers aren't just gifted hardware and documentation to write the drivers so they're a generation or two behind.

Counterintuitively; using the latest kernel can be more stable as bug fixes are merged.

RME does have a few supported cards (I use one) but they're mostly the ADAT ones. And the driver is in-tree.

Answer: a war of genocide and extermination attempted by 6+ Arab/muslim majority states against the nascent nation of Israel, fortunately for all involved they completely failed and in fact ended up losing land. While they did succeed in ethnically cleansing the Jews from any land that did end up under Jordan and Egyptian occupation, and they did expel (ie ethnically cleanse) Jews from most Muslim majority countries, they failed in their overarching goal of finishing Hitler’s work of exterminating all Jews.

Certain morally degenerate groups see this failure (of killing all Jews) as an absolute catastrophe and thus name it the Nakhba.

Oh so you're talking about replications in a very specific field, one completely different from the example you're using elsewhere of climate change.

Your first step is "It's a group of scientists and their work was reviewed, so they are probably all dishonest."

Even that is an unreasonable step. It is very possible for a single person to deceive their peers.

Deductive reasoning like this works so much better for Sherlock Holmes, in fiction. In reality, deductive reasoning tends to re-enforce your biases and ignore the vast possibility space of alternatives.

I find the dedication to these tools kind of amazing. I mean, presumably author can move files on the desktop for free without using valuable tokens here even if they're not aware of how to work in Powershell!

The success stories can be pretty amazing, but the horror stories are very funny.

Will the gains continue apace and Gemini 8 in 2026 is actually able to create somewhat maintainable and complex systems composed of many parts and real world infrastructure?

Or are we leveling off and going to end up somewhere around... unbelievable generalist who writes code well in small segments but occasionally just nukes all your work while apologizing profusely?

> And before email we had mail, handled directly by the government, although reading mail is more difficult without leaving traces.

At least in my country, there has been serious laws protecting the users from police opening letters (1962:700; Postlagens tystnadsplikt). This was changed in January 2023 because people exploited it to send drugs thru post office [1].

Of course without any protests in Sweden because again people don't realize their rights to privacy are taken away from them.

Show HN: Geo Calculation Toolkit API
by pepper40 | 2025-07-23 14:37:11+00:00
Hi all,

I’d like to share a project I’ve been working on: Geo Calculation Toolkit API — a lightweight REST API that performs common geospatial calculations using coordinates and what I refer to as Geo Objects.

(Geo Objects include shapes like polygons, circles, polylines, and other forms with spatial meaning.)

[Why I built this]

A few years ago, I developed a real-time location tracking system. It was a rewarding experience to solve real-world problems using spatial data.

That project left a lasting impression, and recently I revisited some of the location-based logic challenges I encountered back then. I decided to turn a few of those ideas into reusable API features that could help other developers in similar situations.

Rather than handling large GIS datasets, this toolkit focuses on lightweight, real-time calculations involving location and spatial boundaries.

[How to try it]

You can find the full documentation and sample requests here:

GitHub → https://github.com/pepper-craft/geo-calculation-toolkit-api-...

To test the API, please include the following header in your requests:

Header → X-RapidAPI-Key: cc8ca2c596mshb17640c8b5cc21bp13445ejsn7a138f181255

The key has a limited quota, so please note that it’s not intended for unlimited use. I hope that’s understandable.

I’d be happy to hear any thoughts, suggestions, or feedback. Thanks for taking the time to check it out!

Elon is willing to lie and his fans are too stupid to see through being mislead. What major targets of teslas have been met? Fsd? Nope. Sub micron tolerance on builds? Nope. None of what he promises happens, but it doesn't stop stock surges. Did doge (shit coin) go to the moon? No. Bunch of chumps got pump and dumped though. Did grok beat anyone at anything? Nope. Is it non-woke? Nope.

Grifting people takes a form of intelligence, i agree, but it is not what we usually mean when we say intelligence in this context.

Nothing can travel faster than light. If the Death ray travels at the speed of light, then the 1,000 years it takes the message to get to us, and the 1,000 years it takes the Death Ray to get to us are exactly the same, so cancel each other out. So it would still be 500 years between message and Death Ray.

If someone dropped a ball from a tall building with a message that said “in 5 minutes, I am dropping a ball filled with explosives”, you would still have the same 5 minutes if the building was 5 stories tall or 200 stories. The message and the danger have to travel the same amount of spacetime to get to you.

One should not use "drop-in" when they have their own query language and seemingly input shape for the /search endpoint (which is also different from Elastic, of course) https://manual.manticoresearch.com/Searching/Full_text_match...

It sounds like they're really targeting the logging search store part of ELK, which can be a perfectly fine objective, but no need to mislead audiences since they will find out and then you've made an enemy

Think of a slingshot? Or a person jumping?[1].

We see this, not only in mammals and muscles, but in organic systems which evolved to trade speed for power by storing mechanical, electrical, or chemical potential energy over time.

Overshoot and damping is the same in reverse: dissipating kinetic energy when you, for example, bend your knees when you land from a jump (hopefully).

Scientists are responding to the incentives of a) wanting to do science, b) for the public benefit. There was one game in town to do this: the American public grant scheme.

This game is being undermined and destroyed by infamous anti-vaxxer, non-medical expert, non-public-policy expert RFK Jr.[1] The disastrous cuts to the NIH's public grant scheme is likely to amount to $8,200,000,000 ($8.2 trillion USD) in terms of years of life lost.[2]

So, should scientists not write those papers? Should they not do science for public benefit? These are the only ways to not respond to the structure of the American public grant scheme. It seems to me that, if we want better outcomes, then we should make incremental progress to the institutions surrounding the public grant scheme. This seems fair more sensible than installing Bobby Brainworms to burn it all down.

The repair market is a pretty horrible disaster zone of stories like that. I popped a 15" MBP screen a few years back and the (£500 paid) replacement lid+screen from a third party had the ghosting problem that was a problem on those. I tried to return it but the seller disappeared. Same with batteries - never last as well as the OEM ones.

> It's worth noting that while these dangers are real, they are largely economic, and so effectively a moral and political choice.

I bet you're right. I'd just add that those are actually more difficult choices than technical ones. These are global issues and we don't have a global moral or political fabric to use, which means the best we'll come up with is a patchwork of competing ideas. If you think the Linux desktop is bad, wait until you see an attempt at a coordinated international response to drought.

For a microscopic view you could look at the U.S.A. and how much five western states fight each other over water rights for the Colorado River. Those states are all part of the same country and they can't even figure it out.

>(all) european governments are terrorist organisations

I'm all for criticizing government actions, trust me, but can we try to make thoughtful criticisms that represent reality?

Or, at the very least, if you're going to use terms as heavy as "terrorist organization", can you provide some more rationale? Like, how do you arrive at equating all EU governments to terrorists?

It's pretty amazing to see what Blacksmith, Depot, Actuated, etc. have been able to build on top of GitHub Actions. At RWX we got a bit tired of constantly trying to work around the limitations of the platform with self-hosted runners, so we just built an entirely new CI platform on a brand new execution model with support for things like lightning-fast caching out of the box. Plus, there are some fundamental limitations that are impossible to work around, like the retry behavior [0]. Still, I have a huge appreciation for the patience of the Blacksmith team to actually dig in and improve what they can with GHA.

It's also annoyingly "bolted on" in the other direction of the experience, too. A family of grown adults sharing is much less interested in things like central billing. There's definitely a sense that Family Sharing sort of assumes a young "nuclear" family with kids in that 1950's stereotypical 2 married adults sharing a bank account, 2 and a half kids and a dog.

I get the vibe that Apple doesn't really want people to use family sharing in the way a lot of people use family plans. Like, it's there so kids with their first iDevice can get some stuff from their parents, but once that kid is older Apple wants them off your family sharing group and on their own personal everything.

I stick through the hassle cause when Google killed Google Play Music I tried out Apple Music by getting on my parents' family sharing and don't mind having one less subscription to pay for as long as they don't care. But it is annoying it puts my account in a state where I can't buy any subscriptions or in-app purchases without it getting charged to daddy's credit card. The workaround I've found is you can go on the Apple Store app/website and gift yourself an Apple gift card and claim it on your account. Then it'll charge to those funds first before the family organizer's credit card.

I don't get this trust discussion. I don't trust myself not to do a mistake, why should I trust somebody else.

Also - while pair programming is great - it does not replace a code review. When you do pair programming you start working on the problem at the same time, you get tiered and annoyed of the problem at the same time. You want to go to lunch break at the same time. All reasons to slip in a sloppy solution and convince each other it is actually ok.

While doing code review you get a fresh perspective on the matter.

> Republicans say that they’re worried about invasion of privacy, that a CBDC would open the door to widespread government surveillance. But remember, these are the people who have handed over personal Medicaid data to ICE to facilitate arrests and abductions. If you think they’re deeply concerned about potential surveillance, I have some Trump family memecoins you might want to buy.

I know it seems like he's insulting Republicans here, but it's clear Krugman thinks so little of his readers.

the thing is California Forever already wasn't that ambitious to begin with. "a medium-dense city with high walkability with less crime and cleaner than SF" is kinda... boring. a startup city should stimulate your imagination, should try some weird new idea what a city could be, but this was just a safe real estate project (the risky thing was just overcoming regulation and local resistance, on which they ultimately failed)

> Police are generally very nice but I've also seen some unprovoked brutality

The so-called israelization[0] of the police. Certainly you see that in the US. If you compare the local police, say, 50 years ago with their counterparts today, you definitely notice a strong militarization. That may be appropriate for special units handling dangerous cases, but it should not characterize the rank and file that handle petty crime or public disorder.

> No state is your friend, its not normally an outright enemy but rather a party focused on its own interests

The state is the only recourse of the common man against powerful private interests. In this case (surveillance, etc), private interest has been used as a way to get around the legal limitations of government. Companies like Google and Facebook can track people with greater ease than the government can.
