This would have been true until ~50-200 years ago, and the advent of modern capital markets. Now, credit is center stage and cash is the sideshow.
Say I'm a lab.

I train a new model. I publish my training data and my training code/workflow.

I then secretly do additional post-training to poison it. I do not release the data or workflow for this.

Now, I publish the poisoned weights and an md5 hash of the poisoned weights.

To you, the user - you have no way of knowing this happened.

You might ask "why not publish intermediate training checkpoints" but those are nondeterministic (in the sense of being not bitwise-reproducible). Anything with shuffling, random initialization, distributed races, driver versions changing roundoff, compiled vs. eager, and a million other factors introduce slight differences that yield totally different training trajectories. So publishing checkpoints does not yield verifiability.

This is not a constructive way to engage with people. Please reply in good faith on HN - there are other platforms if you prefer otherwise.
$5 does not make sense, and there must be some qualifer on that we're missing.

Napkin math:

(27 minute flight) * (25000 lbm TOGW) * (Earth gravity) / (~10 average L/D) * (160 KTAS average) / (70% propulsive efficiency) / (97% coulombic efficiency) * ($50/MWh) = $30

(Add residual kinetic energy upon landing too)

Side note: Heart also has a weight issue here they'll need to overcome if they want to certify under FAR Part 23 (as their 19-pax spec implies); TOGW limit for that is 19,000 lbm.

There is a word for that. It is "heaviest", not "largest".
> Largest Electric Aircraft

"Largest" is just straight-up a false claim. [Solar Impulse](https://en.wikipedia.org/wiki/Solar_Impulse) and [Helios](https://en.wikipedia.org/wiki/AeroVironment_Helios_Prototype...) were electric and had over double the wingspan, just to name a few of the ~dozen examples.

Heart's engineers should be proud of this genuinely impressive accomplishment, but they need to rein in whoever is writing their PR pieces.

Why use this over Equinox's Module, plus jaxtyping? That seems like the cleaner (and more established) solution, but maybe there are pros/cons I'm not seeing.

This is a desperation move from the LLM providers here. Just think: if you were Sam Altman, and you actually had strong evidence that practical AGI was as imminent as claimed - would you be spending your time building AI-slop TikTok and a smut bot?

I love the concept of this and hope Slate survives, but $27.5k is too expensive for what they're offering. With the Kia Soul at $21.5k and with more features, and the Honda Civic at the same cost, the value proposition isn't there for many people.

Minimialism is great, so long as the price also reflects that.

Re:You're probably using uv wrong on Thursday August 28, 2025 @07:06AM (#45050716)
This was a disappointing article: based on the provocative title, I was hoping to learn something new. Everything in here is already clear to anyone who has read the "Getting Started" page of uv, and I don't know anyone who is making these mistakes (system-wide package installs on a venv-first package manager?) with uv.

Yes, it is completely wrong. If this were a valid explanation, flat-plate airfoils could not generate lift. (They can.)

Re:Laplacian Mesh Smoothing by Throwing Vertices on Monday March 17, 2025 @05:41PM (#43392999)
Funny you should mention that! The surface of a trampoline can actually be modeled as a 2nd-order wave equation PDE, which uses a Laplacian spatial kernel - for the same reasons this is called Laplacian smoothing!
This is a good question. It looks like Kalshi (which hosts the underlying market in question here) in fact does pay interest on both cash balances and open positions, at a reasonable market rate: 4.05%. https://kalshi.com/blog/article/interest-cash-open-positions
You imply that the title "King of America" is pejorative, but did he or did he not refer to himself as a king? As far as I can tell, he endorsed this title.

To add on this, prediction markets currently put Trump Sr. as 8.5% likely to win the 2028 GOP nomination (electionbettingodds.com). So, I wouldn't take your "he'll be done in four years" as certainty. The market thinks things are far more precarious than you do.

> when it stops being laminar the flow separates

Not true, laminar/turbulent and attached/separated are independent descriptors. Flow can be laminar+attached, laminar+separated (e.g., laminar separation bubbles), turbulent+attached (e.g., the majority of boundary layers on large aircraft), or turbulent+separated.

...that's the joke.

> literally no errors in its operation are tolerated

Aircraft designer here, this is not true. We typically certify to <1 catastrophic failure per 1e9 flight hours. Not zero.

Disagree. The kind of serious plagiarism that's alleged in cases like this, Claudine Gay, Marc Tessier-Lavigne doesn't happen by accident, it's deliberate. There are plenty of academics, both minorities and not, who are capable of original thought (and not resorting to plagiarism).

I can't wait for the day that AI is used to expose the fakers en-masse. Previously, they got away with plagiarism through obscurity - no longer. The sooner we can excise these freeloaders from our professional institutions, the better.

I did not go though the grueling process of writing an original PhD thesis, just to share a title with those who plagiarized their thesis.

Re:Solar will get too cheap to connect to the power grid on Tuesday September 03, 2024 @08:22AM (#41434246)
Solar can absolutely be modulated; in fact, it's perhaps the easiest grid-scale power source to modulate since this can be done solid-state: just tune the MPPT to operate off-peak if needed.
