Show HN: I created an AI app that creates endless language learning scenarios
I created LinguaLearn.ai to solve the repetitiveness of traditional language learning methods. It generates dynamic conversation practices across 30+ languages (including less common pairs like Korean→Spanish), with customizable scenarios and difficulty levels (A1-C2) delivered in WAV format accompanied by a transcript. The courses are similar to those produced by the Foreign Services Institute in the mid-20th century, which are very effective.

Tech stack highlights:

- Natural conversation generation in any scenario

- Cross-language learning support (learn any language from any language)

- Infinite number of scenarios (you can be really specific and i.e. try "restoring antique barometers from the Victorian era" or for a laugh you can try "falling out of plane and encountering amazon women").

- High-quality audio generation

- Difficulty-aware content generation (CEFR levels A1-C2)

- Full transcript generation

Currently in beta, offering 5 free lessons/month.

Here is an English -> Latin American Spanish HackerNews themed example:

> As an aside, did you find anything that was effective for bringing you back to that old level of performance?

Not really. I'm 38 now and I haven't made it back to previous levels of fitness, and I suspect I might not in some ways. Recovery was way faster than I expected once I gave it a chance, though. And it is despite not being as disciplined as I should be. It made me realize building fitness while you're young is huge; it lets you build it back a lot easier the second time around. Even so, I eventually kind of hit a wall where getting back has been a lot slower. I rapidly recovered maybe half-way, then it was back on a slower track. My deadlift feels frozen.

I have some thoughts about this, though. I'm starting to think attaining that level was never the point. While I was grinding out PRs, the primary side effect of that journey was a dramatically improved quality of life which I wasn't fully aware of until I lost it... And I could have had that same quality of life (minus the odd injury, too) without pushing nearly so hard or getting so far. Realizing that, I let myself worry less about numbers or how I compare to others and focus more on how something will tangibly benefit me. Lifting more will offer very limited tangible benefits according to my experience (lifting couches easily is nice and all, but rarely useful, and they can only get so easy to carry...)

Really it's about losing the ego for me. There were days I should have been climbing stairs at the park like my elderly neighbour, but I felt sorry for myself, embarrassed at my ability, and did nothing instead. Fit in the exercise and movements you can manage, not the ones you believe you should be able to do. Not pushing your limits in a specific way doesn't equate to never progressing or taking care of yourself. In fact, so much of this is psychological, I'd posit that humility will ultimately lead to improving your fitness simply because your ego won't hold you back so often. It's practically inevitable that we'll experience setbacks; what matters is how we respond to them, not how much we can lift the day after.

The worst thing to do is nothing at all. I must have lost 20lb of muscle and gained ~60lb of fat. Muscle is coming back, but the fat is stubborn.

Where I am recently vs where I left off (1RM):

Deadlift
402.5 --> 360 (was exciting to put 8 plates on again!)

Squat
320 --> 265

Bench
245 --> 210

Run (best distance)
43km --> 12.3km (could improve, but don't really focus on it anymore)

Run (best pace for 10k)
4:17/km --> 5:42/km

Maybe something like 75% of the way back? Worse if you factor in sane baselines rather than assuming starting from 0. When I started trying again, these numbers were abysmal. My running pace was close to 7:00/km and it hurt like hell. My deadlift was under 200 on a 5x5 program, vs ~310 today.

Also... Maybe it was nerve damage, but any overhead exercise is trash and not recovering. I used to clean well over my bodyweight and it was an exercise I really loved. These days I struggle to throw 130lb over my head, and I went from pull ups doing ~20 reps with 45lb strapped to me to struggling to pull off 10 reps with no weight.
My apologies. I'll edit out the leading question. It just seems outrageous to me to say "the game hasn't been improved except it added multiplayer" when multiple pieces of the engine have been re-written. New game play loops added, bugs squashed, updated content, and entirely new ways of generating planets, flora, and fauna have been added.

I feel it is akin to saying FPS games haven't improved since DOOM (95), or simulation games haven't improved since Deus Ex. Are both excellent examples of their genre? Yes, absolutely. Are they still some of the most fun you can have in a game? Yes. Holy crap yes. But to ignore improvements made in the last 3 decades of game development and storytelling just because another game hasn't improved on every single aspect aspect of them is a wild perspective.

Denying the improvements Hello Games has made over the last 9 years feels as if it can only come from a perspective of "I don't like it, therefore it is bad". Which to be clear, again, it is fine if you don't like a game. I don't like WoW, haven't since before Cataclysm. I don't like Diablo III in the same way I liked D2 (and as a result haven't even played D4). But those are personal preferences to me, and both games contain numerous improvements over their predecessors. Just not my bag.
I guess my problem is that I had no idea that he changed his visual appearance so these references just confused me. I'm not really following his personal life.
Think a little further, and you might see that the amount you've recently eaten has very little relevance to how much you need to eat in the near future.
I wonder if I got my share of iodine growing up, or maybe too much, while playing with nitrogen triiodide?
Its like the image you generated in Photoshop released as creative commons, not the Photoshop source code.
I wouldn't say that it was a good investment, or even too much of an investment at all. A lot of it was procrastination, escapism, self-sabotage, etc. There were times when I could overlay a sort of canon to my character's activities that was pleasurable to think about. I spent a lot of time wanting the game to be good, but some glitch or design decision would always get in the way.

But I'd say one of the best experiences I had in the game was becoming self-reliant at the start of a new save. Struggling not to die evolves into having enough resources to survive indefinitely by manual resource harvesting, which evolves into setting up crude crafting pipelines, which then evolves into advanced harvesting and manufacturing, enabling easy interstellar travel and self-sufficient freighter bases. But that can only happen once per save. And it's only really satisfying on survival or permadeath. The other modes are essentially just a no-risk sandbox.
Applaud the effort, but it's weird seeing python (and es6) living more and more on top of native static analyzers/transpilers .. at which point will they become a frontend syntax for ocaml or julia ? :p
I believe the latest on zoned devices is that they are scrapping the explicit zone operations API and are letting the OS merely provide a "region hint", to separate writes by the expected lifespan of the data stored. That could be as simple as different zfs datasets using different hints, if one dataset is archival and another contains actively-overwritten data.
Yeah I was imagining something like the TLS session tracing feature in Wireshark that lets you see all the packets related to a single TLS connection.

I currently struggle debugging opaque containers and VMs that run lots of concurrent async jobs, having some kind of tool to trace and group syscalls through the stack would be amazing.
That's not what the link claims.

The combination of flouridated water, tooth paste, and other sources, etc can lead to levels that can cause problems, but it's not as simple as "fluoridated water bad".
Code Quality AI Copilot
I have been working as a software engineer for 8 years. I have always suffered from bugs, edge cases, performance bottlenecks, and a lack of effort in writing unit tests. You didn't notice that, you missed that, the production server crashed, I triple-checked the code, but I was too tired to find this small bug. I decided to start developing a product to address these issues. This is not just another copilot focused on code writing. Instead, it will focus solely on augmenting humans to improve the quality of the software they write. Future updates will enhance it with context-aware and dependency/call graph-aware inference, and more.
It would help to have an example, but this kind of reminds me of a difference in perspective I've experienced with some people when engaging in dialog in real life.

The only way I've found to describe the difference in perspective I experience with some people is that I'll establish a thread with the intention of abstract curious exploration, not necessarily having anything to do with a discrete concrete problem, fact, or event, and they'll interpret it as though I'm looking for an answer to my specific personal problem, then getting frustrated when I steer it back to a more theoretical anecdote.

Most recently we were walking by a marina, and I was talking with them about their interest in getting into sailing. Tangentially, I posed the rhetorical question of "Hmm, I wonder how the municipality permits/taxes/allocates property when it comes to it being on the water? As in, is there a finite amount of shoreline that someone could have the right to build a dock on a charge for parking space?".

They immediately got frustrated that I was asking them exactly what the dollar value was that this specific Marina would be paying, but I was just establishing a vague idea to talk about, whereby if they had any insight, it would be something to discuss hypothetically.

In other cases it's been the economy, as in what effects might be had if X hypothetical policy change was passed, and they've answered with advice on specific personal investment mechanics as though I'm trying to solve a personal financial problem and looking for an account to open.

Reflecting on this, although different than your quandry, seems to come down to whether someone is intuitively an abstract thinker or likes that sort of discussion, or whether they're more about the concrete details of some specific case, and uninterested in intangibles.

Note that I also don't shy away from personal discussion, it's just that there can be more to explore in curious, abstract, larger scale topics, and it's an element of chemistry whether someone will run with your type of communication
Completely ignorant about how it works but I wonder if medical costs come into play here? Those can get rather sizeable rather quickly in the American for-profit healthcare system.

Can't imagine most prisoners have good insurance but I could be completely wrong here.

Most people will prefer a commonly accepted version of truth; autistic folks tend to be willing to violate that status quo and can get in trouble for it.

Remember to be pragmatic and not die on a hill for the sake of an argument that isn't worth the trouble: Pick your battles.

And make sure your facts are really facts. Facts are hard. Bring solid information to back yourself up.

And keep in mind that truth tends to be very good at winning its own fights in the long term. If patience is an option, make use of it and play for the long game.
Or just unicode. Standard digraphs ftw (xcompose, wincompose...). It's even typed in the same way (_4 ^+ etc) - and maybe there's tex tools that output unicode these days where possible?

H₂O, NH₄⁺, NO, HCO₃⁻, HPO₄²⁻
Contrary to was is said in the article, the 50$/100$ compensation was announced shortly before the update. It is no compensation for the mess they caused.

I still have not restarted my phone since the update. But my wife has and her phone does not hold charge for a day, compared to 48h before the update. Battery percentage gone completely unreliable. She's only doing slow charges since then in an attempt to have battery management chip somehow recover. Hard to see what they tried to "fix"
> How do you even eat 3 kilograms of cheese in one day?

You slice it in small pieces. And add some wine. And a friend to call 911. /s
> ...and I'm not sure that will change. The thing is, the "drive-managed SMR" models I've managed to get my hands on don't have a zoned storage API. I'm not sure how a filesystem (or application that directly goes to the block device layer) is supposed to work with them intelligently.

Mostly by making large sequential writes. F2FS is a lot faster on a consumer drive-managed SMR drive than the others (at least until you need to fsck / upgrade kernel version / do any of the actions that utterly suck with f2fs).
It’s downvoting blatant propaganda.
Self-driving makes the most economic sense when fewer people are in a vehicle. With a large van or bus, the cost of the human driver is split between more passengers. Also van or bus service is less compelling to individuals, as it makes them beholden to bus stop locations and schedules instead of picking them up and dropping them off when and where they want.

Adding support for wheelchairs introduces new failure modes that would require more software and/or human intervention. For example: Wheelchairs need to be strapped down for safety, and not all wheelchair users can do this themselves.
Terrible music? You know you choose what you listen to, right?
It's a little dogwhistle implying prejudice is good, actually.
The R1-Zero paper shows how many training steps the RL took, and it's not many. The cost of the RL is likely a small fraction of the cost of the foundational model.
Typically wording will either be defined in the law, or decided by case law. Legislatures will usually include very long sections on definitions to try and reduce the amount of judicial leeway.

For instance, in Texas motor vehicle code regarding driving under the influence, there is a definition for "Motor Vehicle." While colloquially a person would assume that such a vehicle should have a motor, the definition actually states:

> "Motor vehicle" means a device in, on, or by which a person or property is or may be transported or drawn on a highway, except a device used exclusively on stationary rails or tracks.

When it comes to laws, you have to read the entire law (including definitions) and not just rely on your own understanding of the terms within. Then it gets even more complicated when it comes to so called "Case Law." This is why companies have entire sections of lawyers to inform their managers on compliance.
Given the openness of their model, that should be pretty easy to detect. If it were even a small possibility, wouldn’t openAI be talking about it very very loudly?
It's all about the right level of abstraction at the right time. The example given is too kind to the reader, I can imagine functions with 1000s of lines with the exact same structure of doing too much distinct sub-steps. Of course you don't want to create something like the indirection hell that frameworks like Spring in Java create but it's not hard to find a middle ground. For instance I find it specially easier to create code like the right-hand side when I'm using test driven development.

Why do you want them explicit in the code?

The tooling producing such annotaion based on historical visits whould constantly change the annotated set of functions, I suspect, whith app versions evolving.

Note, the inactive code parts are very often in 3rd party libraries.

Some are also in your own libraries shared between your different application. So the same shared library whould need one set of split-annotated functions for one app, and another set for another app. So these conflicting sets of annotations can not live in the library source code simultaneously.
It's easier to work in terms of "logically valid vs logically invalid" rather than "true vs false". What even is universally true, anyway? There are always axioms and assumptions.
Being confident enough to let people think you aren't fashionable is a statement on its own :P
Despite really disliking the game, but also still playing it enough to apparently notice "many, many glitches" in recent updates, it's pretty obvious that they either have some bone to pick with No Man's Sky or just enjoy being a bit contrarian. Or maybe they're having a bad day. In any case, their comments don't seem to be in good faith.

I never understood why people will keep playing games they don't like. It doesn't make any sense to me. If I don't like a game, I play something else.
The genre is called "sandbox" or "simulation". See Minecraft, Garry's Mod, The Sims, etc. Not all genres are for everyone.
It should be possible to learn to reason from scratch. And the ability to reason in a long context seems to be very general.
The suggestion that any large-scale AI model research today isn’t ingesting output of its predecessors is laughable.

Even if they didn’t directly, intentionally use o1 output (and they didn’t claim they didn’t, so far as I know), AI slop is everywhere. We passed peak original content years ago. Everything is tainted and everything should be understand in that context.
That would be wishful thinking. I think he just meant, close female beings.
Absolutely:
Architects vs Builders
Project Managers vs Project Engineers
Planners vs Doers

I used to think it was just an experience/wisdom thing - e.g.: when you're younger, you tend to be biased to action, builder/doer mindset, "what and how", "fact-based". Then as you become more experienced, you tend to plan more, focus on the bigger picture eg: "why and when", "story-based"

But the longer I've been around, I now see that people are just all wired differently.

The Myers Briggs test[1] is an interesting exercise to identify these traits (and a lot more).

I've done it multiple times over the years and while I'm certain I didn't use the exact same answers each time, the results always converge on the same personality type.

I didn't say those were the only options.

What you wrote is that a library "costs too much for the benefit it provides". What I'm saying is that there are many other things we currently pay more for that provide even less benefit, so in relative terms libraries are quite far down the list of expenses to be worried about.
The distinctions sound a bit too congratulatory.

Reframe as "quibbler vs reasoners", maybe, and see where it takes you.

Or "proposers vs disposers"

Or look at the Big 5 personality profile attributes of Agreeableness and Neuroticism
>That doesn't mean the deep seek technical achievements are less valid.

Well, that's literally exactly what it would mean. If DeepSeek relied on OpenAI’s API, their main achievement is in efficiency and cost reduction as opposed to fundamental AI breakthroughs.
Idk, popular people and probably influencer types look cool with a phone. They look like a VIP, people are constantly texting them, it looks like they're constantly socializing, networking, etc. Same with social media, they have like 5 million friends and it looks like a lot's going on in their lives.

That's probably the difference between how cool people use technology vs nerds or dorks. When I use my phone, it's either to look something up, study or learn something new, read the news, or talk to my mom. I would imagine I probably don't look cool using my phone.

Joking aside, I think one thing that I really don't like about smartphones and texting entering our lives is that when you're out for food or coffee people get on their phones, and it feels antisocial, like you can't talk to them now without interrupting them from whatever they're doing on their phone. In the past, I remember, if people had nothing to say, they would just sit there and look off into the distance. It all felt way more social back then, when people got together they interacted more.
According to the current best guess, fluoridation lowers IQ scores:

We shouldn't discount a thing for which there is absolutely zero evidence? Sorry that's not how it works.
I think it's a United States thing. There are other countries where all salt meant for human consumption must be iodized.

You didn't get my comment it at first--it's fine, dude. Every other user understood it right away, so no problem.
Not sure what you mean; the things you list that your PM has done seems like just another day at the office for Trump.

Trump has already done quite a few crazy things since his inauguration. And I'm judging that by what I'm hearing from people who are directly affected by his actions, not by what I'm hearing from the media.
There's no public evidence to that effect but the speculation makes a lot more sense than you make it sound.

The Chinese Communist party very much sees itself in a global rivalry over "new productive forces". That's official policy. And US leadership basically agrees.

The US is playing dirty by essentially embargoing China over big AI - why wouldn't it occur to them to retaliate by playing dirtier?

I mean we probably won't know for sure, but it's much less far fetched than a lot of other speculation in this area.

E.g., R1's cold start training could probably have benefited quite a bit from having access to OpenAI's chain of thought data for training. The paper is a bit light on detail on how it was made.

So I'm not terribly familiar with Bluetooth. Are these something that can be exploited by an unpaired device?

"Google Android on a Pixel 4a is vulnerable to remote code execution by arbitrary nearby wireless devices" is certainly a better reason to not use one than "security updates have ended".

The evidence indicates not taking a position is the optimal position.

I have a lot of respect for CEOs who just focus on being a good CEO. It's a hard enough job as is. I don't care about or want to know some CEO's personal position on politics, religion or sports teams. It's all a distraction from the job at hand. Same goes for actors, athletes and singers. They aren't qualified to have an opinion any more relevant than anyone else's, except on acting, athletics, singing - or CEO-ing.

Sadly, my perspective is in the minority. Which is why I think so many public figures keep making this mistake. The media, pundits and social sphere need them to keep making this mistake.
Don't get attached to your weaknesses, like "this is just who I am". That's just another story. For example - it's relatively easy to gain quite a bit of compassion/empathy.

I can't say I did much w/ NT and parallel ports beyond attaching printers. I'd imagine it could be pretty awful in the "SPP" days, especially with people trying to connect ZIP drives, "Backpack" CD-ROM drives, tape drives, etc. I suspect floppy drives, which I also didn't use under NT very much, could also play hell w/ interactivity.
