Look up the provided numbers if you disagree.

You're comparing the Sun's illuminance at Earth (10^5 lux at 1 AU) to all starlight combined (10^-4 lux), then trying to work backward to what a single star should provide. That's not how this works.

The question isn't "what's the ratio between sunlight and all starlight." The question is: what happens when you move the Sun to stellar distances using inverse square law?

At 1 AU: ~10^5 lux

At 544,000 AU: 10^5 / (544,000)^2 = 10^5 / 3×10^11 ≈ 3×10^-7 lux

That's the Sun at Sirius's distance. Multiply by 25 for Sirius's actual luminosity: ~7.5×10^-6 lux.

Your own Wikipedia source says the faintest stars visible to naked eye are around 10^-5 to 10^-4 lux. So we're borderline at best, and that's with the 25× boost.

But moreover, you said "the difference between all starlight and just Sirius would be around 10^2." There are ~5,000-9,000 stars visible to the naked eye. If Sirius provides 1/100th of all visible starlight, and there are thousands of other stars, the math doesn't work. You can't have one star be 1% of the total while thousands of others make up the rest - unless most stars are providing almost nothing, which contradicts the "slightly brighter" compensation model.

Address the core issue: inverse square law predicts invisibility. The 25× luminosity factor is insufficient compensation. Citing aggregate starlight illuminance doesn't resolve this.

I have one of these that I use when dealing with retailers for which the phrase "I don't have a smartphone" does not compute. Saves the hassle of having to explain it every time, and so far I'm the only one using my made up number, so they "remember me" or whatever. But they can't actually call, and that's the point.

Which is fair as is not expecting everyone to be able to deliver a barnstorming talk. At least not without training.

I'd also flag that the audio is not good which isn't your fault. The trend towards conferences just pointing a camera at a lectern and throwing the footage on YouTube is unfortunate especially when it replaces circulating the slides as opposed to augmenting them. As a form of archive for attendees to review it works but not as a distribution channel.

A is the remote, B is a coworkers commit, C is mine (iiuc jj uses stacked commits instead of branches)

Let's remove the merge conflict and keep the commits in alphabetical order

B pushes a breaking change, I push a commit to C without knowing.

Are my builds and PRs now at the mercy of changes and events outside of my control?

(my hunch is that there are a bunch of confusing situations in jj like git, and that being different enough will cause user churn and people will stick with the tool they already understand the quirks of)

It may or may not work out. Once you are not actively involved, its not per your vision anymore anyway. And at the end of the day, if you don't think e.g. in this case its very hard compete with Adobe and I really don't want to risk my payday, you'll sell it and move on to do whatever next you want to do.

If we want something to last, I think open-source is the solution.

Agree on the click-baity part, but as for being wrong... not if we're really pedantic. As you've said, Gabor and wavelet are basically generalizations of the Fourier Transform, not actually Fourier Transforms. Just like FS/DFT/DTFT aren't really Fourier Transforms either.

On one corner of the square, you have Fourier Transforms, which are essentially contiguous and infinite. On the opposite corner, you have the DFT, which is both finite (or periodic) and discrete. Hearing is more akin to a Fourier Series, which is finite/periodic but contiguous. That's probably not what the article aims at addressing, though.

But then wavelet transforms are different from Fourier Series again, because you have shifted and stretched shapes (some of them quite weird) instead of sinusoids.

But yeah, colloquially, I agree, the ear is indeed doing very Fourier-y things.

It's hard to say with Google as you don't know how much of the revenue was increased by having the AI stuff. The CEO sounds upbeat:

>We are seeing AI now driving real business results across the company. We delivered our first ever $100 billion quarter. Five years ago, our quarterly revenue was at $50 billion. Our revenue number has doubled since then, and we are firmly in the generative AI era.

They also do a lot of different stuff in AI, like they make their own TPUs and "Anthropic recently shared plans to access up to 1 million TPUs". So some of the business is a bit Nvidia like.

Even in that case this is a military aircraft, one of the most highly prized secrets many nations hold. Probably the most reasonable response to an ejection the aircraft could take is to nose dive into the ground and slam the throttle to afterburners, which isn’t far of what will happen naturally as soon as the pilot isn’t asking the plane to stay straight and level.

> One can lead a meaningful, enjoyable life while also considering their finances.

This is where I disagree. I think there's a certain amount of naivety required to pursue meaningful things. There's so much in life that makes no financial sense that creates meaning. The moment you start having to think sensibly from a financial perspective, is when so many of these things no longer make sense.

Once you're plugged into the system there's almost no turning back.

Case in point. Potential customers will see this dismissal as the equivalent of how long they expect this pricing to remain. You’re free to increase the price in a year and when customers are irked, “why isn’t it $5 anymore?” They’ll be met with “that’s not recent.” “That was so long ago”

Exactly the EU isnt a country and China still produces more pollution than all 27 countries combined.

"My maths" is that countries cannot use per captia stats as an excuse to produce tons of pollution. Would it be acceptable for every country to pollute as much as China if every country in the world had 1.5b people? No it wouldnt we would say thats to many people.

If a country wants to have 5million people and produce 15(units) of co2 per captia thats fine that is not globe threatening levels of pollution its living within their means. However if that country were to have 2 billion people and had a per captia of 10(units) I would say they need to significantly reduce that to about 2.5(units).

Whereas you'd be making the argument that the country is actually doing a lot better even though they produce 20billion(units) total.

Bah. I posted it but I didn't keep it open on my phone. The tldr:

They moved offices, informed wise of a change of address. Wise asked for proof of address. They sent a phone bill. Wise rejected it because the terminology of bills in New Zealand is different to the US (i.e. here bills are usually labelled Tax invoice rather than Bill). Wise support agent also made a barmey suggestion on how to get around it that they didn't follow. Another Wise agent called them back agreeing that the document should be accepted and resubmitted on their behalf. Later the document was rejected again and then their account was closed without any further communication from Wise. Later the author's personal wise account was closed just for being associated with the company.

They're not just nerds, they're power users. These are different things.

Pretty much everyone is a power user of SOME software. That might be Excel, that might be their payroll processor, that might be their employee data platform. Because you have to be if you work a normal desk job.

If Excel was simpler and had an intuitive UI, it would be worthless. Because simple UI works for the first 100 hours, maybe. Then it's actively an obstacle because you need to do eccentric shit as fast as possible and you can't.

Then, that's where the keyboard shortcuts and 100 buttons shoved on a page somewhere come in. That's where the lack of whitespace comes in. Those aren't downsides anymore.

I dunno, the current approach seems quite reasonable. In the grand scheme of things the overwhelming majority of the Earth's surface is empty space where a plane crash is unlikely to cause much damage. You also have the complication that military pilots usually try to make sure their plane will crash in a "safe" area before they eject - many have died because they waited too long to eject trying to avoid a populated area. Giving the plan a mind of its own after they pull the handle would be unlikely to go over very well. I believe the scenario of a pilot ejecting from a perfectly good plane that keeps flying for more than a few seconds has only happened perhaps a dozen times in the entire history of aviation? Not really worth worrying about.

It is a common misconception that the "expert" knows the best. Expert can be a trainee, or may be motivated to make more for its organisation or have yet to encounter your problem.

On the other hand, if you are using your car for a decade and feel it needs a new belt - then get a new belt. Worst case scenario- you will lose some money but learn a bit more about an item you use everyday.

Creatives now have access to a pro-level tool for free with the option to pay extra for AI features.

Also very curious, as a former Wise user who stopped using them after they demanded impossible KYC requirements (proof of address with address components that simply don't exist for my address, luckily with no money in the account, but didn't budge even when I reached out to support) and then seem to have silently dropped this months later (still not using them - not going to risk that they come back with more bullshit when they have money to hold hostage).

Wait, is there any way to get this information onto a privacy-based blockchain like Oasis? Someone would own a Tip - perhaps they could be compensated for it and Tips aren't made public by default?

The more you write, the more you can read from others, perhaps? Some type of value needs to be assigned to Tips. Best ones can go public, or pay to make it public?? Decentralization would ensure uptime. GlassDoor already has some revealing company reviews.

Show HN: DeepShot – NBA game predictor with 70% accuracy using ML and stats

I built DeepShot, a machine learning model that predicts NBA games using rolling statistics, historical performance, and recent momentum — all visualized in a clean, interactive web app. Unlike simple averages or betting odds, DeepShot uses Exponentially Weighted Moving Averages (EWMA) to capture recent form and momentum, highlighting the key statistical differences between teams so you can see why the model favors one side. It’s powered by Python, XGBoost, Pandas, Scikit-learn, and NiceGUI, runs locally on any OS, and relies only on free, public data from Basketball Reference. If you’re into sports analytics, machine learning, or just curious whether an algorithm can outsmart Vegas, check it out and let me know what you think: https://github.com/saccofrancesco/deepshot

If the baseline is ~2c/kWh solar in a good location and they are forced to buy 10x as much solar panels to cover winter use they are now spending ~20c/kWh on solar panels but on top of that they also need to pay for hydrogen generating equipment which only gets used for a few months a year, hydrogen storage equipment, and hydrogen specific generators plus presumably a backup diesel or gas based generator + storage system.

In 20 years it might make sense but today green hydrogen is several times more expensive than gas even when you can use cheaper electricity, can make use of the equipment year round, and have the benefit of larger economies of scale. Even if the goal is completely about climate change locating that same equipment in the lower 48 states is just a much better idea.

I said Switzerland was labelled a currency manipulator - its attempts to devalue the Franc was in response to the sharp rise in its value as a result of Covid and the markets plowing money into safe-haven assets. This presented a real problem for the country at the time, and the primary dynamic at play wrt exports in the country is actually between CHF and EUR, not CHF and USD. The US designation was widely considered arbitrary iirc, putting Switzerland into the same grouping as countries like China, which have vastly different reasons for devaluing their currencies, and arguably ones more in line with what the US was actually supposedly targeting.

So I haven't claimed that Switzerland is a currency manipulator, nor that this would be a good thing, nor that its efforts to devalue its currency had anything to do with the US. I don't see what the contention is here - unless it's that only the US is allowed to be "independent" (i.e. above all international law), here wrt the ICC, while other countries must curtail what is in their national interests (like not having their export markets decimated) for fear of provoking this one special, privileged land?

If the argument is that the US can enforce its agenda on other countries and they must just suck it, then sure. But that's not an argument about fairness or what's right, that's an argument about what to expect from the actor with the biggest stick.

The article details the story of a business that tried to change their address in NZ. Thier documents (while correct to NZ) didn’t match the criteria of Wise and then Wise effectively closed the account. The support and appeal process was basically nonexistent and even by the end article it is unclear that the business owner were even able to retrieve the funds in the Wise accounts. Also the author’s personal account with Wise was also closed.

I hope this is a very brief overview of the article, which I would encourage people to read. In speaks to the huge imbalance in power and accountability in dealing with some companies

You're both working on the same branch on the remote? It will refuse to push unless you do `jj git push --force` at which point it will overwrite your coworkers work with yours. This is regardless of conflicts, like with git you have to pull the remote work locally, rebase on it, and then push it.

> iiuc jj uses stacked commits instead of branches

Locally jj doesn't really use branches, you can just create a commit on top of any other commit without creating a branch. It does represent branches (it calls them "bookmarks" for whatever reason) and pushing is pushing a bookmark to a git-branch on the remote.

> Are my builds and PRs now at the mercy of changes and events outside of my control?

In context of the United States, there are a small number of actors that stand to lose billions to renewables.

I live in the Northeast. Solar reduced my grid demand by 40%. That translates to a full recoup of the investment in 60-65 months with subsidy, 100-110 without. The unsubsidized payback period is 1/3 of the projected useful life of the panels.

You know it’s a good idea because opponents big argument is safety of rooftop installers and future workers disposing of solar panels, topics that these folks DNGAF about in the least.

They shouldn't do that. I get how adding more checks obviously helps in a way, but only if you ignore the cost. It's not worth the effort that you could instead spend writing better tests. Most of the time your type is like FooFactory which doesn't tell you much anyway.

Then again it's not so bad if you're willing to make AI add all the types and not even care.

> At the cost of not being able to actually provide the same throughput, latency, or memory usage

Only memory usage is true with regards to Java in this context (.NET actually doesn't offer a shared thread abstraction; it's Java and Go that do), and even that is often misunderstood. Low-level languages are optimised for minimal memory usage, which is very important on RAM-constrained devices, but is could be wasting CPU on most machines: https://youtu.be/mLNFVNXbw7I

This optimisation for memory footprint also makes it harder for low-level languages to implement user-mode threading as efficiently as high-level languages.

Another matter is that there are two different use cases for asynchronous constructs that may tempt implementors to address them with a single implementation. One is the generator use case. What makes it special is that there are exactly two communicating parties, and both of their state may fit in the CPU cache. The other use case is general concurrency, primarily for IO. In that situation, a scheduler juggles a large number of user-mode threads, and because of that, there is likely a cache miss on every context switch, no matter how efficient it is. However, in the second case, almost all of the performance is due to Little's law rather than context switch time (see my explanation here: https://inside.java/2020/08/07/loom-performance/). That means that a "stackful" implementation of user-mode threads can have no significant performance penalty for the second use case (which, BTW, I think has much more value than the first), even though a more performant implementation is possible for the first use case. In Java we decided to tackle the second use case with virtual threads, and so far we've not offered something for the first (for which the demand is significantly lower). What happens in languages that choose to tackle both use cases with the same construct is that in the second and more important use case they gain no more than negligible performance (at best), but they're paying for that with a substantial degradation in user experience.

It doesn't use Fabric under the hood, where did you hear that?

> Also, what makes you think it’s the most popular server?

Because it's the only server software that can actually scale and support a long-term server with feature and bugfix stability. Its popularity bears out in what hosting companies say people are most commonly using. Though I'm not sure if there is a specific publicly published statistic to point to to prove this - there is bStats global stats, but it is biased towards the Paper ecosystem.

Fabric is getting close with certain optimization and bugfixing mods, but it's still not there. Paper has a checklist of what optimizations and fixes must be included for a release to proceed, whereas Fabric ecosystem is still a hodgepodge of different things that are only available on specific Minecraft versions.
