> [....] Ignoring the following factors means we are leaving useful information on the table:

> 1. The review histories of related cards. Card semantics allow us to identify related cards. This enables memory models to account for the review histories of all relevant cards when estimating a specific card’s retrievability.

I've been thinking that card semantics shouldn't be analyzed at all, and just treated as a black box. You can get so much data off of just a few users of a flashcard deck that you could build your own map of the relationships between cards, just by noticing the ones that get failed or pass together over time. Just package that map with the deck and the scheduler might get a lot smarter.

That map could give you good info on which cards were redundant, too.

edit: this may be interesting to someone, but I've also been trying to flesh out a model where agents buy questions from a market, trade questions with each other, and make bets with each other about whether the user will be able to recall the question when asked. Bankrupt agents are replaced by new agents. Every incentive in the system is parameterized by the user's learning requirements.

> because they've got allies in government right now steering them contracts

Is that because palantir takes them out for golf outings and steaks? Or is it because palantir promises certain results and outcomes to them once the product is in place?

> There's a ton of conspiracy theories about them because their founders are tech-right ideologues.

Yea, it's just the ideology of their founders, it has _nothing_ to do with their actions and partnerships.

> I'd pretty much guarantee that if we'd elected the most mega-woke president in US history instead of Trump and they wanted to commission a huge government data project to analyze the entire American workforce to look for racial, ethic, and sexual orientation biases, Palantir would bid on that contract.

"They're evil and they don't care who's buying."

> but the bad stuff they're doing is the fault of your elected representatives.

That's not how morality, ethics, or the law works.

> People voted for this.

Literally _no one_ voted for this. The people who wanted DOGE to clean up government spending did not in any way think that all federal data, including their own private medical data, would be, or even need to be, fed into a private company to be used in service of the problem.

This is ridiculous apologia for evil. What is wrong with this site? If there's even a single dollar of profit on the table then civil rights are the first thing the "hacker news types" sacrifice. It makes you all seem gross and unapproachable.

Chatbots != LLMs.

We've had chatbots for a long time before LLMs, and while they're of course much more limited as you have to explicitly program every thing it should be able to do, by that very virtue, hallucinating is problem they do not have.

For this kind of customer service chat scenario, I find them much better than just a free style LLM trained in some internal docs.

(Though really, probably the ultimate solution is a hybrid one, where you have an explicitly programmed conversation tree the user can go down, but with an LLM decoding what the user is saying into one of the constrained options. So that if one of the options is "shipping issues", "my order is late" should take me there. While other forms of NLP can do that, LLMS would certainly shine for that application)

I’m not really sure what cutthroat and cooperative mean in this context.

I see society as being cutthroat at the larger and more economic scales (e.g. global, obtaining / keeping your place within the elite of your country, etc) and more cooperative at the smaller scales (e.g. neighbours in your street, your friends, business partners).

My daughter started commenting on people's appearance around age 5+ because she learned it from Peppa Pig. Everyone always talks down to and about the Daddy pig constantly. They try to incorporate some 'good' behaviors in the story but certain 'it's just a joke' jokes end up leaving more impressions on the kid than the shoehorned moral of the story. It took us a while to teach her how it can hurt others if you comment on things (even if they are technically factual statements). On the other hand, she learned some simple but useful things from Bluey that we weren't successful in teaching effectively. e.g. She learned to speak up and tell when Dad(me) was overdoing 'fun' things (literally an episode with exact same concept where Bingo has to tell her dad the same thing). She learned to be compliment and acknowledge many things verbally (instead of saying 'why do I need to say it, they know it already').

The best way I have found to use tmux is to unbind everything and set only the things I use for my workflow. Then the configuration (.tmux.conf) becomes the docs.

I was inspired by the "How to Configure tmux from scratch" post [1].

I came up with my use cases:

- I want to create sessions

- I want to open and close windows

- I want to create split panes

- I want to use vim-style text select

- etc.

Then I made mappings for the things I care about for my workflow specifically.

Before this, I would accidentally hit a keybinding while doing something else and not know how I got to that state, taking me out of flow to troubleshoot.

Afterwards, only the keybindings I have defined take action.

Now tmux fits like a glove. Because tmux is so stable, I haven't had to touch my config in years. It's worth the one time effort.

That's the whole point. They were willing to die for it forever and at some point we weren't anymore.

That's how war works now. It's always been true to some extent but conflict is just getting more and more asymmetrical with no obvious upper limit.

At some point the Houthi in a cave with a five hundred dollar DJI drone and rage in his heart is king in that world: the only way to lose is to care about something that hasn't already been taken from you. You'll never kill all of them. Not with a nuclear bomb.

The US wins on logistics because it has a lot of stuff already built, and anything we need we can build in the US and get it out of the US quickly.

This quickly falls apart in the US if we go civil war on each other. We are technologically fragile. If just a small portion of the people of the US went around shooting electrical distribution, fuel refining and NG compression facilities the US would have one of the worst humanitarian disasters of the last 50 years, maybe longer.

This said, there are a number of countries that would love to see us do this to each other.

Well I kinda do agree with that, it feels like using not getting the hang of AI will leave you behind because AI in 10 years will be so much better - to a point we can't even estimate right now. But I think AI will make life a lot better and will actually help solve inequality since providing quality development during early years and help support children after the first few years of becoming independent (I still consider people children until around 21 to 25 years old).

AI will help close the gap between the people who were privilidged and given the environment to learn versus those who didn't.

However, beyond that I have absolutely no idea what will happen because I had a friend sending me porn that grok generated (the moderation is a joke). AI girlfriends will definitely be a thing and a lot of people will use those services, but I can't really wrap my head around what that entails for the future.

Of course some people want that. And at the moment they can prevent it. But those methods may stop working. Will it then be alright to do it? Of course not, so why bother mentioning that they are able to prevent it now - just give a justification.

Your license is probably not relevant. I can go to the cinema and watch a movie, then come on this website and describe the whole plot. That isn't copyright infringement. Even if I told it to the whole world, it wouldn't be copyright infringement. Probably the movie seller would prefer it if I didn't tell anyone. Why should I care?

I actually agree that AI companies are generally bad and should be stopped - because they use an exorbitant amount of bandwidth and harm the services for other users. At least they should be heavily taxed. I don't even begrudge people for using Anubis, at least in some cases. But it is wrong-headed (and actually wrong in fact) to try to say someone may or may not use my content for some purpose because it hurts my feelings or it messes with my ad revenue. We have laws against copyright infringement, and to prevent service disruption. We should not have laws that say, yes you can read my site but no you can't use it to train an LLM, or to build a search index. That would be unethical. Call for a windfall tax if they piss you off so much.

I recognize that you think this is a great injustice towards something, but since the level was moved from .05 to .02 (in 2001), the number of traffic deaths in Norway (of which 64% involved alcohol over the legal limit at the time) has dropped by about 2/3. Simply put, fewer people are drunk driving and fewer people are dying due to it.

FWIW, the level was set at .02 because it was the closest to zero one could get and still have a reliable measurement on breathalyzers at the time.

No one said it was as black magic. In the context of OCR and parsing PDFs to convert them to structured data and/or text, rendering is a completely different task from text extraction.

First of all, I don't condone the unlinking of snapshot_collision_airbag-deployment.tar after the upload, but, OTOH, I can also understand why something like that would be done, too. (If you were an owner of the car, would you want a subsequent owner to have the records of your crash? This is why I hate all these privacy advocates, because they ruin it for everyone.)

If you've ever worked at any company where security and privacy are taken seriously, you'd be fully aware that things like logging incorrect password attempts is a straight up CVE waiting to happen, even though it's something that a legitimate user might as well want to be happening to find out who's trying to break into their system. Thank the privacy advocates.

But I fail to see who exactly is misled by the marketing, ESPECIALLY given the non-stop negative media attention Tesla has always had.

I mean, it's literally already called FSD Supervised, and previously it's been FSD Beta. How exactly is that not self-explanatory?

But if you already a conclusion, the name is irrelevant. I mean, did you ever look at the Autopilot article in Wikipedia? It's about the aircraft system. Why do not we not FAA complaining to Boeing and Airbus that their airplanes have this super-misleading "autopilot", even though the pilots must still be supervising the tech?
by tharne | 2025-08-04 20:48:37+00:00
The fact that you think that's a big number just underscores how dire Europe's security situation is at the moment. One hundred billion Euros sounds like a lot, but China spends two and a half times that much on defense every single year, the U.S. spends 10X that much every single year, and even the Russians spend more than that every single year. Nevermind the fact Europe needs to play catch up here, not just keep pace.

That doesn't really match my experience. Usually if my problem is not unique it's already documented somewhere and I've solved it that way (And support generally puts some effort into documenting the non-unique problems to reduce their workload). If I'm calling support, it's because I've exhausted all other options and I've either concluded I need them to do something I can't do with an online form or the information is not at all accessible elsewhere, in which case first line support is nothing but an obstacle.

The reality is that European solidarity is not ironclad either. Is the US, or Germany, or Sweden more likely to fold and deactivate* weapon systems under nuclear blackmail?

It sounds hypothetical but seriously, what would Gripen do if tactical nukes were dropped on Estonia and Putin threatened the same on Sweden if they didn't back off? I don't know, and you don't either.

> This may be obvious to people who do this regularly

This is not that obvious. Calculating VRAM usage for VLMs/LLMs is something of an arcane art. There are about 10 calculators online you can use and none of them work. Quantization, KV caching, activation, layers, etc all play a role. It's annoying.

But anyway, for this model, you need 40+ GB of VRAM. System RAM isn't going to cut it unless it's unified RAM on Apple Silicon, and even then, memory bandwidth is shot, so inference is much much slower than GPU/TPU.

Recommended it before in other threads, I'm a big fan of CloudMailin [0] -- they've got some great inbound and outbound services, generous free tier, very simple integrations, useful and reliable dashboard. I've used SES, SendGrid, MailGun, Hive, Klaviyo, etc, but at the end of the day had an overall easier, better, more enjoyable experience with the bare simplicity of CloudMailin.

This is the actual answer

I was in the IC when Palantir was being rolled out and took a bunch of their training courses at their facilities in Georgetown

They have the data storage that complies with DCID and RMF ATO requirements across every IL and compartment

Before Palantir the only thing that we had was Analyst Notebook and you had to have a CD to run it and manage your own data repos locally

Palantir was entirely browser based and you didn’t have to manage data at all so they killed AN almost immediately

I can say that I am not particularly concerned with compile-time range checking. I agree with you that it is a massive headache that is almost always a huge waste of time. Even in dependently-typed languages, tracking ranges and bounds ends up requiring an incredible amount of bookkeeping that definitely does not seem worth the effort in the vast majority of application code.

When I wrote this blog post, I used a very simple datatype because it was an extraordinarily simple example, but given many of the comments here, it seems it may have been too simple (and thus too contrived). It is only an illustration; don’t read into it too much.

I'm not affiliated with the site I submitted, but some just really love stone walls, especially those of us here in New England. I'm part of a "New English Stone Walls" Facebook group that has ~65,000 members.

To me (I'm in CT) there's something really cool to be in a forest surrounded by trees but see a perfectly made stone wall just there in the "middle of nowhere." I think about how much time and effort it took back in the early ~1800s to clear all that land, move all those rocks across fields without modern machinery, and put so much effort into constructing these walls. Some are over 6 feet wide and many are in incredible shape for being put together ~200 years ago.

There's also the "Stone Wall Initiative" spearheaded by Robert Thorson of the University of Connecticut that also has tons of info:

https://stonewall.uconn.edu/

(He also has a really good "Stone by Stone" book available on Amazon.)

I can't think of another cartoon targeted at that young an audience that I'd even consider sitting down and watching a half-dozen episodes of without a kid around, but I can imagine doing that with Bluey. Like I've for-sure left it running for multiple episodes after the kids left the room, and enjoyed it.

Older-audience stuff like Avatar: The Last Airbender or Justice League Unlimited, oh yeah, for sure, but something specifically aimed at lower-grades elementary school kids? Nope, can't think of another, not even nostalgia shows from my own childhood. I'd maybe do an episode just like "oh wow, remember this?" but not a session watch.

I once bought one of those alarms that brighten along with the pattern of natural sunlight in the morning (and dim in the evening), as I don’t get much natural light in my bedroom. The time display on it was so unbelievably bright at its lowest setting that my sleep was worse until I piled stuff up in front of it. I don’t even bother with it anymore.

There is truly a scourge in the EU of increasingly intrusive "safety features" which I truly believe are making cars less safe.

I've been driving a family member's new Nissan. Nice car for the most part, but it has this "safety" feature (that's on by default and cannot be permanently switched off, thanks to the EU) which watches out for the white stripe on the right-hand side of the road and JERKS THE STEERING WHEEL when it thinks you're "too close".

Where I often drive, there are many narrow roads. No yellow line in the middle of the road. The only way to avoid hitting oncoming traffic is to drive with your wheels on the white stripe when you meet another vehicle. This can be stressful enough in itself, especially when the other vehicle is some huge bus or semi truck. Not exactly the time you want alarms going off AND YOUR STEERING WHEEL TURNING BY ITSELF. I've taken to calling it the car's auto-crash feature. Always gotta remember to disable the auto-crash. Every time I start the car.

I got so annoyed I looked up the relevant directive. Turns out new cars are required to have a lane assist feature. It is required to turn itself on automatically, and it is required to warn the driver using at least 2 out of the 3 methods: sound, visuals, haptic. So the steering wheel jerking isn't even just a bad implementation, it's the law.

Sigh.

I agree I feel like it’s just blatantly funneling me into those dubious buy this font sites. I have somewhat better success with http://www.identifont.com/ usually

I don’t think the proposed font is correct either, I’m not even sure the concept of font works for that example though. Mainly the arches on the m are wrong, too arch like and whereas the example is more teardrop.

I'm shocked it didn't occur to me to wonder whether it had been AI-extruded, until I saw everyone else talking about it. The thought of passing on advice, which I myself first received about a generation ago, really was as far as I got.

On the other hand, I have yet to take on a client this year, and so my perspective on AI developments at the IC level is mildly idiosyncratic; I know a grain of salt is required, but not how large a one, and my own experiments reveal a radically different set of capabilities and drawbacks than the technology's manic or epistaxic boosters like to describe.

Judging by what I'm seeing lately here and elsewhere, the workaday tech industry world must be developing into a genuinely horrifying grind, and I'm glad to be out of it.

Thanks, added Warp to the list with the following data:

Up to 150 AI requests/month → about 15 coding hours/month (assuming 10 req/hour) with frontier models. The Free plan explicitly supports frontier models like Claude Sonnet 4, OpenAI o3, and Gemini 2.5 Pro.

That puts Warp at #2 on the list, right below Gemini CLI.

It’s a generic argument that can be applied to a whole class of claims. I see smart people falling into this trap all the time. Someone is making a claim by presenting a series of steps that seem quite reasonable. You then are left in a position where you can either: a) accept the overall conclusion, or b) attack the individual reasoning steps. All I’m doing is pointing out a possibility that your reasoning steps can be entirely plausible while your conclusion is completely wrong.

With the notable exception of gpt-image-1, discussion about AI image generation has become much less popular. I suspect it's a function of a) AI discourse being dominated by AI agents/vibe coding and b) the increasing social stigma of AI image generation.

Flux Kontext was a gamechanger release for image editing and it can do some absurd things, but it's still relatively unknown. Qwen-Image, with its more permissive license, could lead to much more innovation once the editing model is released.

That would be good and all...

But do you have actual evidence that we need it? (Instead of just "nice to have".) Because everybody just repeats that without evidence, like the OP.

There are plenty of reasons to expect the OP's prediction not to hold. I don't know how things play out in practice, and I don't think I've ever seen anybody that knows it.

the internet needs micropayments (probably millipayments). if crawlers want to pay me a penny a page, crawl me 24-7 plz

if I am willing to pay a penny a page, i and the people like me won't have to put up with clickwrap nonsense

free access doesn't have to be shut off (ok, it will be, but it doesn't have to be, and doesn't that tell you something?)

reddit could charge stiffer fees, but refund quality content to encourage better content. i've fantacized about ideas like "you pay upfront a deposit; you get banned, you lose your deposit; withdraw, have your deposit back", the goal being simplify the moderation task while encouraging quality.

because where the internet is headed is just more and more trash.

here's another idea, pay a penny per search at google/search engine of choice. if you don't like the results, you can take the penny back. google's ai can figure out how to please you. if the pennies don't keep coming in, they serve you ad-infested results; serve up ad-infested results, you can send your penny to a different search engine.

So where's your unbiased data then?

Where's your data that these nags make everyone safer, when it's widely known that they simply result in people turning off the entire autopilot/FSD when the operator needs to stop paying attention to the road, to avoid the nags and the penalty strikes?

Where's all the news reports about the crashes without the autopilot engaged? If they were as rare as the autopilot ones, surely we'd have seen some of them covered by the media, right? Or are they so rare that not a single one has happened yet, hence, the lack of any reports being available?
