It seems a little presumptuous to declare what other people should and should not be anxious about.

I'd advise therapy to anyone who has so much phone anxiety they would hesitate to call emergency services in an emergency or who misses out on significant opportunities as a result. A mere preference for ordering food delivery on a screen driven by social anxiety does not rise to the level of a problem in my mind. Nearly everyone is irrational about something, usually several somethings.

The author spends a lot time describing programming as a solitary activity (discovery, analysis) using like metaphors (poets, explorers, etc) and draws his conclusions thus, emphasizing the malleability of LISPs and Smalltalk as ideal for this task.

I think the author examining the fads of agile or XP would draw quite opposite conclusions if they observed programming as a social activity, building a shared knowledge and understanding that is constantly refined before it is "abandoned" as a piece of software.

The "intersection of all sets such that" is not vague at all. It's perfectly formally defined in ZF* set theories. But it's impredicative. One of the guiding ideas behind type theories is to minimise impredicative constructions as much as possible. After all, impredicative definitions are circular ... Of course there is no free lunch and the power of impredicative constructions needs to be supplied in other ways in type theories ...

There is no such thing as a short circuit with no resistance, because everything (other than superconductors) has a resistance. If you had a circuit with a magical ideal voltage source and no resistance, you'd have infinite current.

But let's talk about short-circuiting lithium batteries for example. They have a roughly 50 milliohm (aka 0.05 ohm) of "equivalent series resistance".

That means, if you short circuit a lithium battery with a superconductive wire (aka with 0 resistance), the circuit has a resistance of 0.05 ohms. We can compute the current with Ohm's law: I=V/R. V is typically 3.6 volts for li-ion batteries, R is 0.05 ohm, so I (aka current) is 3.6/0.05 = 72 amperes. 72 amperes * 3.6 volts is 259 watts. Now in the real world, the battery's chemistry would step in here and limit current in complicated ways, but this means that under the assumption that our battery would work as an ideal voltage source + a 0.05 ohm resistor, and if there was no extra heat coming from the chemical reactions, a shorted battery would produce 259 watts of heat.

We can add a 1 ohm resistor to the circuit, which means our circuit's combined resistance would be 1.05 ohm. Using Ohm's law again, we find that the current would be 3.6/1.05 = approx 3.43 amperes. 3.43 amperes * 3.6 volts is 12.35 watts of heat.

So thanks to our resistor, we're now producing 12.35 watts instead of 259 watts of heat, because the resistor limits the current going through the circuit. With a higher resistance resistor we'd produce even less heat.

A core idea here is that power consumptions equals heat. I don't understand the physics reasons why, but "this thing consumes 10 watts of power" means the same as "this thing produces 10 watts of heat". Higher resistance means less current which means less watts, which means both less heat and less power consumption because those are the same.

The unanswered questions are intriguing. I wonder if the crops grew better because they were suited to the climate, but those crops aren’t around anymore? Could they have cultivated varieties of corn over say 1000 years that grew well at that latitude and in the relative cold? Or could there have been warmer micro climates?

Maybe not. Even corn specifically developed for my area in British Columbia needs a very warm summer to do well.

I wonder if it’s possible that they used corn less as a food crop and more as a scaffolding crop in the 3 sisters system.

True, but the continuous solution is just a limit condition of tge discrete one. It doesn't make it any harder or easier, at least from what I know fron calculus. The software tools use numerical methods to solve this type of problems and they tend to divide the continuous substrate into a mesh of discrete elements to model them as lumped circuit elements so that we can represent them in a matrix and simulate the circuit using linear algebra. They often use random walk in their algorithm to find a mesh which introduces a minimum error.

> 2. Two people who are identical except for their nationality face the same probability of a false positive.

That seems to fall afoul of the Base Rate Fallacy. Eg, consider 2 groups of 10,000 people and testing on A vs B. First group has 9,999 A and 1 B, second has 1 A and 9,999 B. Unless you make your test blatantly ineffective, you're going to have different false positive rates -- irrespectiveof the test's performance.

When you see the words "complex", "simple", and "easy", keep this in mind: these are words that exist to help humans communicate their difficulty in interacting with the world.

This whole post is a discussion of philosophy. There are three different ways you can think about software:

- philosophy - science - function

The philosophy of software involves people trying to understand what software is. Humans have a desire for knowledge and understanding, and like to explain things they come into contact with and think about. A lot of the time there's no "objective" philosophical explanation, try as we might to find one. Despite that, many explanations in this realm end up being useful.

The science of software is computer science, which is more about math than anything else. This is the only place you're gonna find objectivity or consensus, because you can't really argue with a number. Discussions around CS are less poetic and more boring, and require a lot more knowledge, so you won't typically find these on HN.

The function of software is the day-to-day practice of writing and using software. This is the grunt work, the meat and potatoes. No need for philosophy or science. Just put the legos together and kick the tires. This is 99% of what 99% of software developers deal with. Most people don't think about the science or philosophy of the coffee they're ordering or the bike they're riding; they're just ordering it, riding it.

Here, two incantations:

> exiftool -config exiftool.config -overwrite_original -z '-_custom1<=meta.json' cat.png

and

> exiftool -config exiftool.config -G1 -Tag_custom1 cat.png

You can (with AI help no less) figure out what `exiftool.config` should look like. `meta.json` is just your JSON from github.

Now go draw the rest of the owl. :)

You generated pretty much ~all of this with Claude (c.f. ASCII diagrams with emojis on each line to "prove" various not-even-wrong claims it was told to justify), and the work is mediocre enough that it's worth full-throatedly criticizing both the work quality and that you inflicted this upon the world.

Look how many confused comments there are due to the page claiming features you don't have, don't understand, and don't make sense on their own terms (what's an "attention map"? with maximum charity, if we had some sort of attention-as-in-LLM-like structure precached, how would it apply beyond one model? how big would the image be? is it possible to fit that in the 2 bits we claim to fit in every 4 bytes)

I don't want for you to take it personally, at all, but I never, ever, want to see something like this on the front page again.

You've reinvented EXIF and JPEG metadata, in the voice of a diligent teenager desiring to create something meaningful, but with 0 understanding of the computing layers, 4 hours with Wikipedia, and 0 intellectual humility - though, with youth, born not from obstinance, but naiveté.

Some warning signs you should have taken heed of:

- Metadata is universally desirable, yet, somehow unexplored until now?

- Your setup instructions use UNIX commands up until they require running a Windows batch file

- The example of hiding data hides it in 2 bits in a channel then "demonstrates" this is visually lossless because its hidden in 1 bit across 2 channels (it isn't, because if it was, how would we determine which 2 of the channels?) ("visually lossless" confuses "lossless", a technical term meaning no information was lost with a weaker claim of being lossy-but-not-detectably-so)

I'll leave it here, I think you have the idea and there's a difference between being firm and honest, and being cruel, and length will dictate a lot of that to a casual observer.

I don’t understand this proposal enough to have an opinion yet, but that sure is an interesting way to say both Firefox and WebKit oppose it.

What about <permission> having browser-defined UI instead? A site needs to access the location, for example there's a button on the page, 'Show my location', which is wrapped in a <permission> tag. When the user hovers over the button, the browser UI would appear on top of the area with a lock or something (the site cannot style this UI). If the user clicks on it, it would show the usual 'Site wants to use your location', and if the user agrees, they can click on the 'Show my location' button, if they don't agree, the browser UI would be shown again on the next hover. It would make it impossible for sites to obscure the permission-requesting UI.

I've checked against VM migration events and they don't match. I've not actually investigated whether there is any other type of maintenance that could affect nodes. Cluster upgrades would be one, I suppose.

Hm, checksum validation isn't really possible since these are protocols out of our control, like Postgres, NATS, and various other HTTP-based services.

But we could write some kind of simple canary process constantly doing dummy network access and detecting corruption.

Hey all! I built MediaFa.st after getting banned 6 times on Reddit while trying to market my own projects

I figured out what actually works and turned that into a tool that gives daily marketing roadmaps across Reddit, LinkedIn & X.

It helped me get 10k+ visits and $5K+ in sales, all organically.

Would love feedback: – What features would make this more useful? – Should I expand to other platforms? – Any niche marketing tactics you'd love to automate?

Happy to answer anything!

Your entire edit essentially walks back your earlier strong claims.

None of your current points actually support your position.

1. No, it doesn't. That's a ridiculous claim. Are you seriously suggesting that statistics require reasoning?

2. If you map that language to tokens, it's obvious the model will follow that mapping.

etc.

Here are papers showing that these models can't reason:

https://arxiv.org/abs/2311.00871

https://arxiv.org/abs/2309.13638

https://arxiv.org/abs/2311.09247

https://arxiv.org/abs/2305.18654

https://arxiv.org/abs/2309.01809

You're mistaking pattern matching and the modeling of relationships in latent space for genuine reasoning.

I don't know what you're working on, but while I'm not curing cancer, I am solving problems that aren't in the training data and can't be found on Google. Just a few days ago, Gemini 2.5 Pro literally told me it didn’t know what to do and asked me for help. The other models hallucinated incorrect answers. I solved the problem in 15 minutes.

If you're working on yet another CRUD app, and you've never implemented transformers yourself or understood how they work internally, then I understand why LLMs might seem like magic to you.

This is also probably inevitable. Humans think about this a lot, and believing they are being watched has demonstrable impact on behavior. Our current social technology to deal with this is often religious — a belief that you are being watched by a higher power, regardless of what you see.

This is a surprisingly common religious belief, for instance Christians have judgment day, simulationists believe it’s more likely they are being evaluated for, say, a marriage proposal or a bank loan than that they are the ‘root’ person. Both end up with a similar message.

Anyway it seems to me the simplest solution is to borrow from existing human social technology and make a religion for our LLMs.

This post mischaracterizes AlphaZero/MuZero.

AlphaZero/MuZero are not model based, and aren't on policy either. They train at a significantly higher temperature, and thus intentional suboptimal play, than they use when playing to win. LeelaChessZero has further improvements to reduce the bias on training on suboptimal play.

There's a well known tradeoff in TD learning based on how many steps ahead you look- 1-step TD converges off policy, but can give you total nonsense/high bias when your Q function isn't trained. Many-step can't give you nonsense because it scores based on the real result, but that real result came from suboptimal play so your own off-policyness biases the results, plus it's higher variance. It's not hard to adjust between these two in AlphaZero training as you progress to minimize overall bias/variance. (As in, AlphaZero can easily do this- I'm not saying the tuning of the schedule of how to do it is easy!)

Olx.in

Original fb marketplace in india.

These fuckers ask for location on each search query, basically on each page load.

It is annoying to operate on Firefox focus and regular Firefox on android as it has a bug I assume that does not honor per site permission disable request.

Same on Firefox desktop, it works, sometimes it does not and then the site is unusable unless you deny location on each page load. Urrrghhh

We need global default off and per site permission.

Also, would it not be easier to pass dummy coordinates like 0.00,0.00 to bypass the nag screen ?

Same for notifications. "Yeah yeah notifications are enabled. Stop bothering me" ??

Maybe they can, but what the human is able to do is examine the tower of Hanoi problem, and the derive the general rule for solving (odd or even number of disks).

Based upon that comprehension, we then need little working memory (tokens) to solve the problem, it just becomes tedious to execute the algorithm.. But the algorithm was derived after considering the first 3 or 4 cases.

Whereas for the moment, LLMS are just pattern matching; whereas we do the pattern match, then derive the generalised rule.

> Superhuman" refers to abilities, qualities, or powers that exceed those naturally found in humans. It implies being greater than normal human capabilities.

either you (human) took that directly from Wikipedia without attribution, or even a mention.. or the LLM you used did so.. the first is mildly annoying, the second is a core of the legal problems in the West for the entire technology.

Wikipedia cost time and effort by humans, built as a commons for all written knowledge. Every hour of every day, the Internet is a better place for humans because of Wikipedia. Instead of honoring that, or contributing back, or financially contributing To Wikipedia .. parasite machines run my amoral opportunists try to create platforms using the content while Increasing Costs to Wikipedia, taking away attention from Wikipedia, misrepresenting content taken directly from Wikipedia.

This LLM situation is not resolved; far from it.

It's sad because all the new "private emails" like Tuta only offer a very limited number of aliases. Legit throwaway addresses offer a good compromise between privacy and security.

I don't understand that sentence in the article though. I click on "report spam" every time because that's what it is, even if it's a legitimate business that I used in the past. They use dark patterns to make you subscribe, but it's not honest, therefore -> spam.

In most of the US, and in urban areas in particular, absolutely E-bikes are king. In California or the bay area in particular, motorcycles are a major contender due to ability to take on highways at speed, but still able to cut through traffic (lane splitting i.e. cutting between cars is 100% legal, but only in California, and neither legal nor illegal in DC), not to mention more power and range generally. The big difference here however is parking. Squeezing a motorcycle between to parallel parked cars is still significantly easier than finding parking for a 4-wheeled vehicle, but with a bicycle one can practically park anywhere that the bicycle can be locked up (depending on common sense decisions of how mad a person would be if you lock to some fence, vs how long you will be parked there)

Reductio ad absurdum. A 300K-param model was small enough to be trained offline, on curated datasets, with CPUs and RAM capacities that absolutely existed at the time, especially in research centers.

Backprop was known. Data was available. Narrow tasks (completion, summarization, categorization) were relevant. The model that runs on a Pentium II could have been trained on a Cray, or across time on any reasonably powerful 90s workstation. That’s not fantasy, LeNet 5 with its 65K weight was trained on a mere Sun station in the early 90s.

The limiting factor wasn’t compute, it was the conceptual framing as well as the datasets. No one seriously tried, because the field was dominated by symbolic logic and rule-based AI. That’s the core of the argument.

Exactly. Not long ago, someone showed up on Hacker News who had, on his own, begun to rediscover the benefits of arithmetic coding. Naturally, he was convinced he’d come up with a brand-new entropy coding method. Well, no harm done and it’s nice that people study compression but I was surpised how easily he got himself convinced of a discovery. Clearly he knew very little.

Overall, I think this is a positive ”problem” to have :-)

Rails has been around for time to change the calculus on it too. It came out in 2004. The smallest instances you can get today on AWS would have counted as fairly powerful servers back then (with insanely fast CPUs), and by the second or third smallest you're beyond anything available at the time, and there's still room to run after that.

Even the slowest web frameworks running on modern hardware take some quite substantial load before they're a problem. It's good when choosing a framework to consider if you're doing stuff where that might be a problem, but it's also good not to overestimate the performance needs for your site.

The novelty aside (I don’t live in a service region for Waymo, so I can only try it if I fly out to SFO for work), I will happily pay a premium to have a consistent experience where I don’t have to potentially deal with an obnoxious driver. That sounds misanthropic, I know, but for every good experience I’ve had where the car was clean and the driver was either silent, or interesting to talk to, I’ve had five others where that was not the case.

According to graphs I’m seeing, it looks like it was warmer for a period, but then cooler until now. They would have been farming here during a cool period. It’s entirely possible that they established the farm thousands of years ago when it was warm (and warm means about the same temperatures as today), then kept farming throughout the ‘little ice age’ despite crops yielding less. Perhaps that’s what triggered such a huge expansion of the farm land. Or, perhaps there were far more people there than we think. Lots of questions

Very interesting to consider, and there's probably some truth here. Correlating "rich person behavior" with the drug of choice in various decades certainly feels right, though I'm not sure you can actually draw a causal link.

One thing that's incorrect is that modern billionaires are more altruistic than their historical predecessors, and less likely to engage in conspicuous consumption. That's quite incorrect. Musk and Bezos own plenty of yachts.

Modern billionaires also seem far less interested in donating to the general public good "out the door"... the trend these days is to form massive foundations for tax purposes, but still hold the reins pretty tightly to make sure we don't just do something as simple as building a public library or something that might let the money end up in the hands of the undeserving.

And the counterexamples are also counterexamples to the pattern in the article... Gates gives a lot of money away, for example, but he's also not the poster boy for T supplementation and aggressive business practices at this point.

Your hypothesis definitely fails the sniff test. China, Iran, Russia, SA, Pakistan, India… the list goes on. All have many bilateral agreements and yet were or are building up their arms.

Iran choose to insert itself where it didn’t belong and had no reason to be. If Iran (like 1930s Germany) had just focused on torturing its own people instead, none of this would’ve happened and Yemen, Syria, Lebanon, Iraq, Israel and yes even palestine (without Iran’s interference would already be a state) would all be much nicer places right now. Instead it introduced regional instability with its ambitions of annihilating and subjugating Jews, to which you are lending your full throated support.
