https://www.bzarg.com/p/how-a-kalman-filter-works-in-picture...

Kalman filters basic concept is essentially this.

1. make prediction on the next state change of some measurable n dimentional quantity, and estimate the covariance matrix across those n dimentions, which describe essentially a probability that the i-th dimention is going to increase (or decrease) with j-th dimention, where i and j are between 0 and n (indices of the vector)

2. Gather sensor data (that can be noisy), and reconcile the predicted measurement with the measured to get the best guess. The covariance matrix acts as a kind of weight for each of the elements

3. Update the covariance matrix based on the measurements in previous step.

You can do this for any vector of numbers. For example, instead of tracking individual objects, you can have a grid where each element represents a physical object that the car should not drive into, with a value representing certainty of that object being there. Then when you combine sensor reading, you still can use your vision model but that model would be enhanced by what lidar detects, both in terms of seeing things that camera doesn't pick up and rejecting things that aren't there.

And the concept is generic enough to where you can set up a system to be able to plug in any additional sensor with its own noise, and it all works out in the end. This is used all the You can even extend the concept past Gaussian noise and linearity, there are a number of other filters that deal with that, broadly under the umbrella of sensor fusion.

The problem is that Karpathy is more of a computer scientist, so he is on his Code 2.0 train of having ML models do everything. I dunno if he is like that himself or Musks "im smarter than everyone else that came before me" rubbed off.

And of course when you think like that, its going to be difficult to integrate lidar into the model. But the problem with that thinking is that forward inference LLM is not AI, and it will never ever be able to drive a car well compared to a true "reasoning" AI with feedback loops.

That is a strange interpretation.

According to you, a drawing equating a black person to a monkey is only problematic if some people do really believe that black persons are literally monkeys? And people who enjoy these drawing are lacking basic biology concepts and would be flabbergasted if they were told that, no, black people is not a different species as distant from white people than macaques or gorillas?

The problem is the message that it carries and how it unities, spreads and empowers racist communities.

"Don't feed the trolls" is a cute saying on the internet, usually said with confidence by people who think they are smart but in fact don't really know about what they are talking about. And the goal is usually to deter a troll from a forum, so they can go to the next one and do the same trolling (so, it does not stop any trolling, it just displaces it). And it is not even clear if it is working.

It is also quite a coward way to response to that. Imagine "oh, these people are beating a foreigner to death. I know what to do: just ignore them, they are doing that for the attention, if we ignore them, maybe they will stop". Trolls act for attention, but these trolls are getting plenty of attention, from racist communities that loves them (and often even manage to groom them). So, who care about "feeding the troll" or "the streisand effect", this has no impact of the damage they are doing.

> Nobody is complaining about trolls being told they are assholes.

In the comment I've answered, you were literally saying that the trolls were unfairly blamed in the same non-logical way one would blame Hindus for their usage of their symbol.

This is Nietzsche’s will to power in its most unforgiving form.

The will to power is not mere survival or dominance over others; at its apex it is the drive to impose one’s own meaning on existence, even when that meaning is written in self-destruction.

It is like Empedocles and the volcano.

Empedocles does not leap to escape mortality; he leaps to overreach it, to force the cosmos to acknowledge his claim, even if the price is erasure.

The penguin would rather perish as itself than endure as something lesser.

For ~15 years, Python's subprocess.Popen.wait() implemented timeouts using busy-loop polling. This post explains how that was finally replaced with true event-driven waiting on POSIX systems: pidfd_open() + poll() on Linux and kqueue() on BSD / macOS. The result is zero polling and fewer context switches. The same improvement now landing both in psutil and CPython itself.

Outer Wilds, and imperatively its DLC, are transcendent gaming experiences.

Like many, I stopped playing my first time over a frustration with the jet pack and ship movement controls.

I returned later, this time determined to master the movement controls only to find that after mastering them you eventually abandon perfect movement for efficiency anyways and perfect gameplay looks a lot like the initial flailings.

Anytime you get 'stuck' in the game the answer is always, "what have you tried, what can you try instead?" Illuminating the tendency to assume an answer, and grow frustrated when it fails repeatedly.

It's certainly a "just play it without looking up anything about it" game. I went in without being spoiled by the "first surprise" that is referenced in this article and was stunned when I figured it out.

Swapping FPS violence for scientific discovery, and a wholesome story centered on the social bonds of music make for a truly wonderful gaming experience.

I highly recommend the game to anyone.

ICE isn't doing police work (police are somewhat accountable to their local populace for keeping people safe), they're ostensibly (selectively) enforcing federal immigration regulation.

But please for the love of god explain how "not following orders" is grounds for immediate extrajudicial execution? because your

"their opinion seems to be ... that the person that got shot did nothing wrong"

definitely seems to imply that 'doing something wrong' justifies any reaction up to and including being shot in the head or magdumped in the back?

Lethal force wielded by unmasked, uniformed, badge-wearing, and bodycam'd police officers is already fraught with enough issues as it is... And at least they occasionally face investigation and punitive measures when they fuck up on the (admittedly very difficult) job and harm civilians unlawfully.

A woman not getting out of the car when being ordered to by unknown masked men bearing weapons is reasonable.

Shooting an unarmed civilian who poses no threat to you is not reasonable. It only serves to undermine the entire apparatus of civil governance as well as the bill of rights that the US government was founded upon. It's shameful and disgusting.

And yes, you're accurately labled a bootlicker if you make excuses to the contrary about how it's _ackshually ok_ to shoot and kill people who don't listen to you because boohoo they made your job harder.

If instead you decide you don't actually want to make such an indefensible stand, and instead motte and bailey your way around the issue by trying to talk about obstruction of enforcement of laws, and fall all the way back to "well ICE is allowed to invade places to get the dirty immigrants, so really all the law-abiding citizens would be fine if they just got out of the way", then you're a coward who wont accept the consequences of their own line of argumentation.

Murdering people (Renee Good) who pose no threat to you is wrong. Full stop. Whether that person did something worthy of a misdemeanor, or arrest, or some other LAWFUL CONSEQUENCE is a different matter entirely.

ICE's continued and flagrant misconduct is a breakdown of the Rule of Law, which literally only works if the populace maintains enough trust in those entrusted to enforce and uphold the law. Destroying that (precious little remaining) trust in a politically motivated boondoggle to "own the libs" is a colossal fuckup.

were you not employed by an employer that was paying your insurance premiums? Heck, when I was in california the startup I was at was paying almost my entire insurance premium.

and in practice, I'd argue I had better quality of care from that than from my socialized insurance in my current country, though the socialized care does have some benefits.

reason for better quality of care is that in the US system for all its problems, the patient is the customer as they have many options and each doctor is running an independent business. my experience with socialized medicine is that the government is really the customer, not me, and doctors are not really running independent businesses (and when they do, they aren't particularly cheap). It's like having a single HMO that gets to decide what you get with little recourse. While some might equate it to health insurance companies in the US, I, at least, felt I had much more flexibility with them.

> So we’re left with one answer: information. But what kind of information are you trying to learn from a fiction book? The book is literally labelled FALSE on the cover.

I learned so many things from fictional works.

Authors don’t just make up lies and say whatever they want. Fiction does not mean everything is nonsense. The worlds that you read about have to be believable and for that to be possible, things have to at least be partially consistent with what we understand of the world.

So many authors do real research when they write a fiction novel so that the world that they’re building can be convincing.

For instance:

* I learned how to drive a stick shift from a Young Bond novel. The author didn’t make anything up, they actually described the way that the clutch mechanism works, and how the character was controlling it with the pedals.

* I learned about Navajo code talkers from a fictional book about World War II.

* I learned about cowpox being used as a smallpox vaccine from a fictional book about a new smallpox outbreak in New York City.

* I learned that Gatorade was developed in Florida from Taken by Edward Bloor.

* I learned a lot about the reformation and the Quakers and early colonial America from the Baroque Cycle, because Neal Stephenson did real research to write that book.

Is everything that happened in the book real? No, because obviously Daniel Waterhouse didn’t exist, didn’t found MIT, and didn’t have some mechanical LLM in the 1600s.

Did some of the things in the book actually happen in real life in order for the author to set that book in the time period? Yes. Like IOUs from goldsmiths acting as paper money, and the standardization of coinage by Isaac Newton.

There is so much factual information encoded into the pages of fictional works that this is the stupidest thing I have ever read on any platform in any circumstance ever.

Pure anti-intellectualism of the highest order. An attempt to undo The Enlightenment.

Yea I had to Google their total headcount when I saw the headline since the number does sound high, but in reality is only 5%.

When you factor in low performers and how most people here would view middle management in any other topic thread, it's not that insane. If in a pool of 20 workers around you, you can't find 1 worker you don't think is a step below the others, your hiring pipeline is better than most.

What are you working on that they are so knowledgeable?Even the best models absolutely make stuff up, even to this day. I literally spend all day every day working with them (all latest ChatGPT models) and it’s still 10-15% BS.

I had ChatGPT 5.2 thinking straight up make up an api after I pasted the full api spec to it earlier today. And built its whole response around a public api that did not exist. And Claude cli with sonnet 4.5 made up the craziest reason why my curl command wasn’t working (that curl itself was bugged, not the obvious it can’t resolve the dn it tried to use) and almost went down a path of installing a bunch of garbage tools.

These are not ready to be unsupervised. Yet.

The competitive reality confronting most global economies right now demands a 3% GDP growth rate or more based on the global average.

But instead we have uninspired so-called captains of American industries who can’t find anything better than payroll deductions to boost the bottom line. Could have hired a small-town middle manager for that level of insight. Dumb people getting lucky is the worst curse for humanity.

These people need a major reality check, https://fortune.com/2026/01/22/how-big-national-debt-when-re...

FAANG companies got to the state that they did, and thus attained national importance, because every asshole in the world bought their thing, on a big or small scale.

The other issue is that major economic uncertainties are keeping companies from spending and creating jobs even though there is work to be done. You’re not going to get the world to play along by being scary. The AI-doom rhetoric isn’t cute, and needs to be toned down if we’re actually going to get anything useful and productive out of these tools. Again, major reality check: we don’t even have proper self-driving cars.

> X11 has basically no development anymore.

Odd. Every few months, I see a new xorg-server version in my distro's package manager.

> That means regressions are entirely ignored.

Should I ever actually have a problem, and it's something that I can't (or CBA to) fix, and my distro's maintainers don't want to try to fix (and then tell me that upstream will never fix), then I'll look more closely at XLibre. XLibre may or may not be a dumpster fire at that point, who knows? If it is a dumpster fire, then I'll look around for other alternatives.

> It's shocking that people still install X11 as a default in [TYOOL]

Nah. It works fine for what I'm doing. I don't do anything that depends on Wayland. The shocking thing would be if I were to waste a ton of time chasing the new shiny... especially when those responsible for the new shiny have been lying for the past 10+ years about how it's ready for everyone's general use. [0]

[0] Perhaps it's ready now, after nearly eighteen years in development. I can't rely on the statements of those responsible for the project to tell me, and I CBA to go searching for (and evaluating the trustworthiness of) information on the topic.

I don’t have a strong opinion on the specific methodology or framing, but this is an interesting model. Since the source is available, you could easily set up a similar tracker with different framing or model sources.

I think AI is overhyped, but this is an interesting application for it. This automates a fuzzy, tedious task where precision isn’t too critical and frequent updates are potentially useful.

Activist orgs with a particular goal or anti-goal could use this to track progress with slightly more impartiality. A meta organization that manages several causes could use multiple dashboards to see what areas are most in need of attention. All without relying on a bored/biased/expensive human to constantly plug in data.

Rust on Linux only works for Linux based servers https://www.protondb.com/app/252490

Apex Legend used to work but doesn't anymore (still marked Silver) https://www.protondb.com/app/1172470

Delta Force used to work but also doesn't anymore (still marked Bronze), people are tinkering with config files but nothing seems to work https://www.protondb.com/app/2507950

NARAKA: BLADEPOINT is working but requires custom Proton, some tweaked settings, launch options, etc https://www.protondb.com/app/1203220

GTA V public lobbies don't work, requires you to tweak launch options, disable battleeye anticheat, seems to just not work for some people. https://www.protondb.com/app/271590

BG3 also seems to require a custom Proton and tweaked settings for some people https://www.protondb.com/app/271590

It goes on and on these were just from the first few games sorted by player count. Much of the tweaking seems to be different person to person, sometimes it just works sometimes it's Nvidia's fault, sometimes it's something totally different. There's a "recommended for tinkerers" option for reviews. To be clear, every single one of these works right out of the box first time on Windows.

> The ICE person states they will not try to enter and if the clerk touches them, they will yank the person out of the building.

I'm not sure what the agent has to do to qualify as a threat to you, but at the very least this is thuggish behavior. The embassy is Ecuadorean sovereign territory where the staff have immunity from US laws, threatening to yank someone out of there is like extracting someone from Ecuador by force. It's highly offensive.

If you tried that at a US embassy you'd probably be shot, but it's generally impossible because they are all heavily secured and fortified.

Thanks. That's not really bypassing iPhone before first unlock. It says only 'partial' metadata, so it's likely just looking at encrypted blobs and making guesses just like file recovery tool would on an encrypted drive. So it's a bit of a marketing gimmick to "leak" that document

> The document does not list what exact types of data are included in a “partial” retrieval and Magnet declined to comment on what data is included in one. In 2018, Forbes reported that a partial extraction can only draw out unencrypted files and some metadata, including file sizes and folder structures.

The dark flows and Loss Disguised as a Win felt quite relatable. I've had 3 days in a row at work where I've vibe coded heavily with Opus 4.5 and was flowing and felt super productive and almost manic.

At the end of every one of those days when I went for a walk with my dog I realized "hold on, I don't need all that crap that it generated" and immediately thought of solutions that required a 10th of the code mass.

I've wasted hours on refining something that was crap. Maybe I needed to do that to discover the simple solutions, maybe it was a skills issue. But I was deep in the dark flow and the amount of code I generated definitely felt like a slot machine rewarding me for losing (time).

> So is it just a wrapper around MitM Proxy?

Yes.

I created something similar months ago [*] but using Envoy Proxy [1], mkcert [2], my own Go (golang) server, and Little Snitch [3]. It works quite well. I was the first person to notice that Codex CLI now sends telemetry to ab.chatgpt.com and other curiosities like that, but I never bothered to open-source my implementation because I know that anyone genuinely interested could easily replicate it in an afternoon with their favourite Agent CLI.

[1] https://www.envoyproxy.io/

[2] https://github.com/FiloSottile/mkcert

[3] https://www.obdev.at/products/littlesnitch/

[*] In reality, I created something like 6 years ago or so before LLMs were popular, originally as a way to inspect all outgoing HTTP(s) traffic from all app installed in my macOS system. Then, a few months ago, when I started using Codex CLI, I made some modifications to inspect Agent CLI calls too.

agent Smith, the one that don't care at all about conforming to POSIX?

"In fact, the way I see things the Linux API has been taking the role of the POSIX API and Linux is the focal point of all Free Software development. Due to that I can only recommend developers to try to hack with only Linux in mind and experience the freedom and the opportunities this offers you. So, get yourself a copy of The Linux Programming Interface, ignore everything it says about POSIX compatibility and hack away your amazing Linux software. It's quite relieving!"

for coding, if you have not hooked up your workflow to a test -> code feedback loop, then you are doing it incorrectly. i agree it doesn't get things right all the time but this loop is important to correct it.

for other things like normal question answering in the chatgpt window, it hasn't really said anything incorrect.. very very few instances.

> Wish someone would wipe my memories of that game so I can play it again.

Felt the same for years, now I am doing a new playthrough.

I figured, of course I know the solution to the puzzle, but I am hard pressed to remember all the details of how I uncovered that answer, and I know that you can uncover the clues in nearly any order so I know this playthrough will be new in its own way.

And I miss the world, and the gameplay.

Human explorers aren't necessarily terribly rational. A bunch of ordinary human pride is involved.

The base on the actual South Pole, far on the interior of the continent, isn't McMurdo where much of that documentary was filmed, it is Amundsen-Scott, and it's named for two teams of explorers who first reached that pole in the same summer, Amundsen (whose team reached it first and returned alive) and Scott (whose team was second and all died)

Scott's plan was crap. To a considerable extent that view is hindsight, but even at the time Scott must have known Amundsen's plan was better. Certainly by the time they reached the Pole and found that they'd been beaten to it, he will have been sure. By that time he was in extreme danger, slowly starving and with a long trek back to any permanent shelter - it would have taken excellent luck (which he didn't get) to make it home alive, and in any case he'd been beaten to the pole.
