Show HN: Ladderr, Voice-First AI Career Coach
by moeinxyz | 2025-09-15 09:33:08+00:00
Hi HN,

I built Ladderr, a voice agent for workplace soft skills. It runs coach-style 1:1 voice check-ins (at a cadence you choose) to keep you accountable and reflect on next steps, and it supports practice, feedback and role-play for common workplace scenarios (business English, giving/receiving feedback, stakeholder pushback, conflict resolution, self-advocacy).

Early MVP - free while I iterate; login required (no credit card).

For now I’m limiting testing to ~25 users so I can respond quickly and incorporate feedback. If you try it, I’d appreciate product feedback to help steer the direction.

Try it: https://ladderr.ai/

Thanks for reading.

My understanding is that x86 implementations use speculation to be able to reorder beyond what's allowed by the memory model. This is not free in area and power, but allows recovering some of the cost of the stronger memory model.

As TSO support is only a transitional aid for Apple, it is possible that they didn't bother to implement the full extend of optimizations possible.

True, they're a great tool and shine in some areas. I especially use LLMs to work as a search engine for me before I start a new project; I use it to critique my implementation plan, I use it to find things that already exist to avoid reinventing the wheel, and I use it as a reviewer while building out my spec/design documents. Both of which I first write by hand then use it to format, give me "ideas" which I cherry pick depending on the scope of the project. YMMV.

Also in the same vein as SQL, I've seen Gemini is pretty good at generating formulae in Google Sheets; I used it to create an optimal player rota for a 24 hr online endurance race me and my friends were participating in using parameters like player_strength, the time slots they were fine with taking up, in order to min-max fatigue and consistency.

Pretty fun.

Well also that you can buy graham cracker crumbs, for making things like pie crusts. My friend gave me a weird look when we went shopping and I picked up whole crackers. And then the revelation that graham refers to a type of flour and is not in itself a brand. And Kelloggs sell the crumbs? Wild.

A biscuit base in the UK would usually require a pack of digestives and a rolling pin. I suppose some supermarket sells crumbled biscuits but...

As an aside, Golden Grahams used to be popular in the UK and I don't think anyone stopped to ask what the name meant.

This is unreal and beyond cool. Instead of measuring seismic tremors, it measures, indirectly, the displacement of the ocean surface. Far from the shore, tsunami waves are very long and very low - so they would appear as the whole surface of the ocean going up and down.

That motion pushes air upwards, resulting in a wave reaching high up through the atmosphere, eventually hitting (!) the ionosphere. I didn't even know acoustic waves would propagate through ionised gas!

Finally, this ionosphere disturbance affects GPS signal reception, and can be measured via ground receiver stations.

The upside of this is that it measures, indirectly, motion of the sea, i.e. actual tsunami activity, rather than monitoring directly the potential causes thereof.

It is crazy to me that it works though!

> even if I optimized my software to the point that it could process the data at 1 Gbps

Are you sure you did the math correctly? We're scanning CT at my work, and we do have scale problems, but the bottleneck is for database inserts. From your link, looks like a shard is 10TB and that's for a year of data

Still insane amount and a scale problem, of course

There needs to be accountablility regardless of intent for policies that affect everyone.

I agree with you though, they know what they are doing and about some implications at least.

I hope most services will just block Denmark though. Any investment in such technologies is a waste and should come to a great cost to developers. In this case Google products in general should be shunned. Not that they were famous for steady support of products instead of quickly killing them.

If it's baked into the tool (can run offline) then it would be unavoidable, need a new version to get a new release on the package manager.

1.2.3 -> 1.2.3+1 (or +anything, date, whatever) could arguably be idiomatic semver though - that's what you do for packaging changes, like updating the description or categories to file it under etc. without actually changing the program.

You're more qualified than most founders I know, not because of degrees or titles, but because you've been deep in the fire and came out with clarity. Burnout isn’t a flaw in your ability, it’s often the cost of high ownership in broken systems. Stepping away without notice sounds like survival, not weakness.

On your questions: I believe portfolios matter less than signal. A solid GitHub readme, a tiny demo with personality, or even a clean writeup can open doors. Hiring today is noisy, clarity stands out more than size.

AI hype is mostly wrappers + vibes. But that's a feature. If you can ship small, real tools that feel smart, you’re ahead. Nobody’s expecting you to train models.

On staying engaged: what helped me was shipping for insight, not polish. Projects as questions, not proof. The goal isn’t “a finished app,” it’s “what did I just learn about what I love, hate, or want to do more of?”

You clearly still care about the craft, about growth. That’s the rarest signal of all.

Rooting for you.

Really appreciate you taking the time to look through the docs and write such a thoughtful comment. You’re right — JavaScript carries a lot of quirks and limitations that aren’t going away, and if you’re building full-scale business apps in the .NET ecosystem, Blazor is a very natural fit.

dagger.js isn’t trying to compete with that class of frameworks. The goal is much narrower: keep a build-free, HTML-first option around for cases where shipping something lightweight, inspectable, and easy to embed is more important than squeezing out type safety or runtime guarantees.

I completely agree that we don’t need everybody moving deeper into JS just for the sake of it. But I do think there’s value in keeping a spectrum of tools alive — from strongly-typed/.NET style systems to small runtime-only JS libraries — so developers can pick the right trade-off for their domain.

Thanks again for the honest feedback; it helps clarify where this approach makes sense (and where it doesn’t).

I'm very sympathetic to this point - regulations are usually there for a reason, and it's important to know what it is - but there's always a grey area between genuine public need and regulatory capture by special interests, which the incredibly dysfunctional nature of US politics hides.

The big ones are probably zoning and protectionist car regulations.

(Note that having a one party state makes a lot of the problems of partisanship go away. However, the problems of "working towards the leader" and the tendency to hide unfavorable news leading to poor decisions are still there. The tradeoff that China has is that, so long as high levels of growth can be delivered, political unrest can be contained, or dealt with by blaming "corrupt local officials" who can then be "dealt with".)

Intel initially claimed Processor Ordering that, IIRC, allows processors doing independent reads of independent writes (IRIW) to observe different orderings. This is slightly weaker than TSO.

In practice Intel never took advantage of this and, given the guarantees provided by the memory barriers, it was hard to formally recover SC, so Intel slightly strengthened it to TSO, which is what was actually implemented in hardware anyway.

I don't think intel ever claimed SC since their first CPU with builtin support for cache coherency (it was the PPro I think?), and the memory model was not well defined before that and left to external chips.

We're not in disagreement here.

It looks like he simply failed to secure the support of all branches of the military and decided against going through with it. That's why I think it's silly to claim there was a coup attempt. At the end of the day, a coup was not actually attempted. They could have charged him with something more accurate like conspiracy. Conspiring to do something is obviously a much lesser crime than actually doing it. They specifically chose to call it a coup for political reasons. Giving up was pretty stupid in hindsight, he's being judged as though he had actually gone through with it. He might as well have tried.

Oh well. Bolsonaro's fate is much less important than the fate of the thousands of people who went to jail in January 8th. I don't believe there was a coup attempt there either. They asked the military to do it and the military did nothing. They can be charged with vandalism, incitation, whatever. They can't be charged with an actual coup attempt. That requires actually picking up weapons and trying to depose the government by force. Asking the military to do it on their behalf doesn't amount to a coup attempt.

For the record: I don't think Bolsonaro is wrong from a purely moral standpoint. My position is that the supreme court itself enacted a silent coup years before these events unfolded. That makes any manuever from Bolsonaro a counter-strike against the real tyrants. Especially since these same tyrants nullified the corruption case against the current president and violated the constitution on a daily basis in order to get him elected in 2022. Now that Bolsonaro's been defeated, the only hope for this country lies in Trump's sanctions as well as diplomatic and economic pressure.

As someone who works in a market, eating anything without cooking or washing it first is a bad idea. Most of it is fine, but people are disgusting and there's no way of knowing how many people have touched your apple, if someone's kid managed to lick it without you noticing, or someone managed to push everything off the shelf onto the nonslip mat before they got stopped. Bagged produce can be even worse, given the amount of condensation inside the bag after it warms up on the loading dock and then sits in the cooler. The mister above the fresh greens and such doesn't do much and they regularly get touched and knocked out. The potatoes are probably the best, as the dirt on them is obvious.

If you live in an area with entitled people and spineless corporate rules that don't allow stores to confront people over pets, that's instantly worse than everything else combined. Pets like to lie on the floor, someone's dog has peed on the floor, 5 different random people have petted hugged or picked up that dog and 3 others since they left the house. One of those people is probably a cashier who then handles every item you've bought. And then someone inhaled pet hair and sneezed.

I can’t remember where I heard this from but I once heard that the ideal political system isn’t democracy, it’s a benevolent autocracy. While the CCP may have some corruption, I do get the impression that it is mostly benevolent and serves China’s best interests. Relative to autocracy, democracy is slow and pulls in different directions due to party politics and elections. I went to a museum in Hong Kong recently. It had a very obvious Chinese bias, but it clarified some things for me about how China sees itself. The CCP sees social cohesion as critical to the security of the state. If we look at Western countries like the US and UK, social cohesion is weakening, we’re extremely divided and addicted to bickering amongst ourselves.

Take the Charlie Kirk murder as a recent example which has sparked heated infighting between the left and right in the US. You’re all part of the same country but you pull in completely different directions and hate each other. Driving wedges like this is a tool adversaries can use to dismantle democracy.

I'm always amazed that techniques like shrinkflation work (or I presume they work, because if they didn't I assume no one would be doing it!). Do the manufacturers just think that consumers won't eventually notice the reduced amount of product, leading to only short-term gains?

Perhaps more people need to stop buying certain brands out of spite when they try and quietly shrink the packages.

Great initiative thank you, it was time to have a better platform. Just created an account with 500gb free and no bullshit. Youtube deleted my account because simply I was showing HugstonOne to the world and that is a violation of their privacy. All I hear from Youtube users is frustration and all are leaving in anger. Personally I don´t like tyranny and will never go back to youtube-google-producthunt... There are plenty of pleasant alternatives. Here my new channel: https://clip.place/w/inRMaEHjNeLvBLAS9Yas89

Some are necessary and some are not, or can be streamlined. In the context of the article, where it discuses China can develop things fast while America cannot, lets take California highspeed rail. - The Buy America law hinders supply choice - Crash test standards are much higher than Europe - Lot of consultation/assessment and pretty much any lobby group could block the construction - Sue friendly environment, so makes things costly.

Just to push back on this slightly, I'm sure I've watched Youtube videos with someone who bake cakes for a living who said they used boxed mixture for most of their baking.

As others have said elsewhere, some of the ingredients involved are not easily available/cost-efficient for the home baker. This means it's more than possible that you will get an objectively better cake from a mix, e.g. from blind tasting.

This does depend on the type of cake you're baking and your expectations of 'better' though.

> Really, 1TB/s of memory bandwidth to and from system memory?

5x is false, it's more like 4x. Apple doesn't use memory sticks, they use on-SoC dram ICs.

The M3 Ultra has 8 memory channels at 128-bit per channel for a total of 1024-bit memory bus. It uses LPDDR5-6400 so it has 1024-bit * 6400000000 bits = 819.2 gigabytes per second of memory bandwidth.

I am counting delays that are always occuring. There is only two reactor blocks that I know that didn't have delays in recent years.

These are build times for just single Reactor Blocks, in 2020 to 2022. https://www.worldnuclearreport.org/IMG/pdf/wnisr2023-v5.pdf#...

Real examples in the last years: Olkiluoto 3 - 17 Years SHIDAO BAY-1 - 9 Years Flammanvill-3 - 17 Years VOGTLE-4 - 11 Years FANGCHENGGANG-4 - 8 Years RAJASTHAN-7 - 14 Years

For me the big blockers for GrapheneOS are still pretty much the same:

* The community is unnecessarily toxic from what I've seen: there's a lot of following dogma without asking "why". It leads to this very insular userbase that often turns outwardly toxic towards other projects, which is an issue that goes forever unfixed (ie. This post on the F-Droid forums originally was far more aggressive towards the F-Droid project before moderators edited it to be less aggressive: https://forum.f-droid.org/t/google-will-require-developer-ve... ). Other, older places I've seen this come "from the top" include hostile relicensing of Vanadium's patches to prevent other Chromium forks from making use of them.

* Instead of blockading SafetyNet as being a user hostile solution, GOS instead... implements their own version of it. Which is hard to see as anything other than basically recreating the same walled garden you get on stock Android.

* Pixel exclusivity is dumb and remains dumb. Pixels are very mediocre devices from a usability angle; they're large, have pretty inefficient battery life and in my experience are prone to becoming hot very easily. (I also managed to randomly brick one during a routine stock system upgrade, so there's that; not on GOS obviously, just noting that the Google side of the flagship Android is pretty lackluster too.) There's also a forever hypocrisy in defeating Google spying... by giving more money to Google. The motives for this seem to mostly be tied to a promise about the Pixel's security chip being open sourced eventually, but this is a forever promise Google isn't willing to cash out on. GOS has a token line on their site saying that most patches can be used on other OSes with little effort, but there's zero effort from any community to actually make these. (The reason for this can be blamed squarely on point 1; there's an insanely hostile reaction to anyone trying to do a fork for this sort of thing, which is basically enabled by the lead devs because of what they did w/ the Vanadium license.)

* Finally, GOS doesn't let you do hosts based adblocking, instead encouraging you to use the Android VPN service instead. A simple solution... that isn't really realistic because the Android VPN service only covers running one VPN at a time, meaning you have to pick between adblocking and privacy/accessing your own internal network.

Finally, a broader problem is that from what I can tell, GOS as a project doesn't quite grasp the relationship between app developer and app user and how it's become toxified over the years. Things like their ongoing signing beef with the F-Droid project (an incredibly niche issue that doesn't matter for most users) suggest to me that GOS is at best extremely naive/unrealistic on the issues that affect app usage for the common user. The problem these days is usually the developer going bad, not a third party.

> spanishconjugator [2], which consistently published ~240 releases per month between 2020 and 2024

They also stopped updating major and minor versions after hitting 2.3 in Sept 2020. Would be interesting to hear the rationale behind the versioning strategy. Feels like you might as well use a datetimestamp for the version.

> tell that to the UK countryside

The UK countryside has already come a long way from where it was 5–10 years ago.

The problem with the UK is the regulatory/government environment.

The incumbent (BT) were given a large chunk of money 20 years ago for fibre deployment, but they were allowed to cherry-pick their deployments and so inevitably chose the low-hanging-fruit of the conurbations.

I would think 100% FTTC coverage will happen sooner than you think. FTTP clearly harder to forecast, most likely another 5–10 years, sadly.

You might see better 5G coverage sooner, of course.

Yeah it’s not clear what China achieved was qualitatively significantly superior than Japan or Korea’s achievements.

I think China’s biggest source of fortune was that their rise coincided with the unraveling of American democracy, which arguably began with the 2020 election, but was well and truly set in motion when American leaders exploited 9/11 and lied to the public to start a war in Iraq.

The value in YouTube is their monetization network which brings real money to the people uploading videos through advetising deals and the premium subscription. This is why YT became such a juggernaut - it's not just covering its tech costs, its also providing folks with real revenue to create those videos.

And this is where Peertube isn't really the same kind of a platform so you won't see the same kind of videos.

I had the same thoughts when studying physics (I have a PhD). Math was some kind of a toolbox for my problems - I used it without too many thoughts and a deeper understanding. Some of the "tools" were wonderful and I was amazed that it worked; some were voodoo (like the general idea of renormalisation, which was used as a "Deus ex machina" to save the day when infinities started to crawl up).

Math is very cool but I think it requires a special (brilliant) mind to go through, and a lot of patience at the beginning, where things seem to go at a glacial pace with no clear goal.
by TheOtherHobbes | 2025-09-15 09:47:57+00:00
Elon does this because being able to order all those people around makes him feel special and important, not because it actually works.

Study after study proves that productivity drops off rapidly when people are tired and stressed - which should be common sense, but apparently it's too common for some of our notables to understand.

So instead of actual work output you get productivity theatre. Everything is dramatic and shouting happens, but - for example - Tesla still doesn't have anything resembling FSD while more modest companies are much further along.

It's juvenile machismo, not adult management.
by TonyPeakman | 2025-09-15 09:48:54+00:00
Totally fair — longevity is a real concern, and I’ve had the same hesitation with new tools myself.

The nice thing about Dagger.js is that it’s intentionally very small and HTML-first. If the project disappeared tomorrow, your markup is still just plain HTML + attributes, and your components are still standard Web Components. There’s very little “lock-in” compared to bigger frameworks with proprietary syntax or build pipelines.

That said, I do intend to keep it alive — it’s under active development on GitHub, MIT licensed, and easy for others to fork or extend. If a year from now it still looks useful, I’d be glad for you (and others) to take another look.:)

Is this how it's measured? Just to see if I got it right:

The atmosphere directly above the tsunami will have a different TEC (total electron count) pattern due to the upward acoustic waves created by the tsunami waves. This patch of atmosphere may or may not be in the line of sight of your many GPS receivers, to some satellite. Those for which it is in the line of sight will show a disturbance. Others won't. You can now cross-compare to "triangulate" where the tsunami waves are.

Cocoa/chocolate is an industry that happens to use a fair bit of child slavery, unfortunately (among other bad practices, I just single out that one because it's the one that I consider the most abhorrent)

Getting a fair trade certification requires a supply chain inspection, and in theory, would not be possible to get for producers which have child slavery in the supply chain. Though of course, supply chain inspections are complicated and I believe this is by no means perfect (nothing is).

Rainforest Alliance certified has nothing to do with ethics in treatment of the humans involved in the supply chain, just environmental impact.
