lnwlebjel··on Building an AI-native engineering org
This is amazing and somewhat insane. It's more like they are building an organism with an immune system than a code base. Interesting that they say only Fable works for them.
lnwlebjel··on As oceans warm, great white sharks are overheating
I agree. I see climate engineering as the short term solution that will get us to the long term solution. Without commenting on this specific implementation, experiments could be done. Many of the aerosol-type ideas are not permanent and would not last (and neither would their impacts). Models are good enough to understand the impacts and if they are not now they can be improved through a cycle of experimentation and further modeling. Other solutions are decades away and they have been for decades. Time to take this seriously. We are already engineering the climate, just not one conducive to life.
lnwlebjel··on Ask HN: Which book are you reading these days?
I'm not much of a tennis fan but I really enjoyed this book. The evolution of training and strategy during his era which is a subtext throughout is really interesting.
lnwlebjel··on NSF faces shake-up as officials abolish its 37 divisions
The restructuring and firings are already happening. The infrastructure is being destroyed.
lnwlebjel··on Lessons Learned Writing a Book Collaboratively with LLMs
Given that humans are 'wired for story', perhaps you should consider indulging. These could be what makes the books stand out after all.
lnwlebjel··on Lessons Learned Writing a Book Collaboratively with LLMs
Thanks for posting this, it's a very interesting case study. Considering that the thing they seem to excel at is this type of writing, it's interesting that they still seem to be only ok at it if you're trying to produce a serious, genuinely useful output. This fits with my experience, though yours is much more extensive and thorough. In particular I fully concur with the voice/tone, and the need to verify everything (always the case anyway), and "Never abdicate your role as the human mind in charge" -- sometimes the suggestions it makes are just not that good.

Question is, do you think this process was faster using the various LLMs? Could two (or N) sufficiently motivated people produce the same thing in the same time? (and if so, what is N). I'm wondering if the caveats and limitations end up costing as much time as they save. Maybe you're 2x faster, if so that would be significant and good to know.

In the abstract, this is similar to my experience with AI produced code. Except for very simple, contained code, you ultimately, need to read and understand it well enough to make sure that it's doing all the things that you want and not producing bugs. I'm not sure this saves me much time.

Seriously! Family of 5? Five bowls, five spoons ... Maybe have some extras in a hard to find place on the rare occasion of entertaining.
lnwlebjel··on B-2 Spirit Stealth Bombers Begin Unannounced Deployment to Diego Garcia
"Briefly, the US has the capacity to decisively win on one or two fronts at a time, so its strategic logic leads it to want to wrap up conflicts in order: put an end to the Ukraine war, and address Iran next, to preserve its ability to respond to a Chinese invasion of Taiwan. The logic of its rivals is then the opposite: to tightly coordinate and threaten to expand conflicts on each front so that the US can’t effectively respond to any. This is a path to a world war."

So, if US hit Iran, we have to watch out for escalation from Russia and China.

where and how does one acquire the '1970's Cambodia feel' without having actually been there?
lnwlebjel··on Of Course It's a Coup
I'll give the flaggers the benefit of the doubt and say that the article has a lot of assertions but little substance backing them up. I've seen comments (indeed on some of the flagged articles) with more substance than this article. Let's see some facts backing up these assertions (or articles with such) because I agree, this is super important.
lnwlebjel··on What's happening inside the NIH and NSF
Insiders have little say. NSF is probably the most merit based system in all the US government. Literally any other program (defense?) is less merit based.

Also, if nepotism and favoritism are the criteria for removal, let's start with the Executive branch.

lnwlebjel··on What's happening inside the NIH and NSF
I can't deny that person's experience but mine has not been that at all.
lnwlebjel··on What's happening inside the NIH and NSF
This is false. The grants were not approved based on race. The grants were approved based on merit toward the goals of the field of science to which they were submitted. Showing how your work had broader impacts toward a more diverse, equitable and inclusive society was one part of a list of many criteria, recently updated here:

lnwlebjel··on Ask HN: PhDs/students, how do you come up with viable problems/solutions?
I'm in a totally different field and this is 100% my experience. Some of the old papers have really great ideas that no one ever worked on, or talk about problems, which we have more data or better solutions/attacks on now. Finding these are like finding gold nuggets - they can set you up for years.

One of the hilarious things about rewatching old episodes of Seinfeld is his use of a cordless phone that I swear is the size of a toaster!
lnwlebjel··on Is the world becoming uninsurable?
This is happening already, it has happened to my neighbors. As resident of CA in a neighborhood which previously was not, but now probably is, 'fire prone' I fully expect to hear from my insurance company to provide evidence of defendable space and other modifications to minimize the likelihood of structure fire.

I've read that once more than about 5-10 house were on fire, there was really no hope of containment, due to the orientation of the streets relative to the wind, the proximity of houses, and the intensity of the wind. Thus the key is prevention -- not letting the wild land fire get to the first 5-10 houses.

lnwlebjel··on Take the pedals off the bike
Lots of comments stating as fact without explanation that angular momentum has no impact on rideability, so here is more information. I had no idea that this had been worked out (more or less conclusively):

"While gyroscopic and caster effects may contribute to balancing the bicycle, they are not the root cause. J. D. G. Kooijman and his collaborators confirmed that the root cause is a front-loaded steering geometry. A front-loaded steering geometry means that the steering shape of the front wheel and frame on a bicycle is constructed such that the front of the bike falls faster than the back. If the bike starts to tilt to the left after hitting a bump and succumbing to gravity, the front wheel falls to the left faster than the rest of the bike. As a result, the bike turns left. The amazing part is that turning the front wheel to the left causes the momentum of the bike to snap to the right because of centrifugal force (just like you are thrown to the right side of your car when making a quick left turn). The right lurch of the bike compensates for the initial fall to the left and the bike ends up straight again. "

This is from https://www.wtamu.edu/~cbaird/sq/2013/04/18/what-keeps-a-bic..., which has a link to the relatively recent paper (2011) providing the most evidence:

The Idea Factory: Bell Labs and the Great Age of American Innovation by Jon Gertner is similarly great for some of the earlier/origin stories of Bell Labs.
lnwlebjel··on Chinese citizen charged with flying drone over key US Military, NASA launch base
More info from a local website:

"Investigators later determined the drone likely flew 1.8 miles from the park into Vandenberg’s restricted area.

Armed with a federal warrant, agents later searched Zhou’s drone and found several photographs of the base taken from an aerial viewpoint. "

and:

"For the past three launches starting with one on Nov. 23 from Vandenberg, SpaceX has inexplicably skipped broadcasting the final minutes of the countdown and initial liftoff. Instead, the webcast started about 45 seconds after the departure.

They also provided a broad 4-hour period as the planned departure for the launch, instead of the typically smaller window that includes the actual launch time.

A source suggested the change could be connected to some sort of national security issue, but officials remained mum about the reasons. " [1]

They arrested him on his way back to China. Sounds like he might get those 4 yrs. Perhaps it's not a harsher sentence because he didn't get anything actually sensitive?

lnwlebjel··on Ask HN: Could I build a radar for tracking cars and boats?
Late to the party, but this is something I've wanted to do for a long time. My background is in signal processing but the hardware has always been somewhat mysterious to me. Here is an interesting link from MIT:

https://makezine.com/article/craft/diy-phased-array-radar-fr...

I really like the idea of using wifi signals, such that you'd have to build a receiver only. I'm not sure what the range would be but it seems like getting traffic speeds in front of the house would be possible.

lnwlebjel··on Ask HN: What's the "best" book you've ever read?
I would put this down as my best book ever. It contains one of the most important ideas (IMO) for a scientist to keep in mind:

“But in introducing me simultaneously to skepticism and to wonder, they taught me the two uneasily cohabiting modes of thought that are central to the scientific method.”

The Cosmos series, which was on PBS when I was a kid IS the reason I went into science.

lnwlebjel··on Nuclear reactors a mile underground promise safe, cheap power
On thing I never see in these discussions is the toll on workers via radiation exposure. I worked at a nuclear plant in the 1990s and the exposure allowed to outage workers who worked six months a year was something like 5 REM, or 50yrs off radiation in 6 months. Are these deaths included in the statistics? It appears not - part of the issue undoubtedly is causal attribution to a cancer that occurs many years later. A cursory search of the literature suggests that not a lot of work has been done on this.
lnwlebjel··on Ask HN: Could true randomness come from sparkles from light reflecting the sea?
I'm not sure if it makes sense from a randomness generator point of view, but it shouldn't be to hard. You could even use the buoy cameras provided by NOAA, eg:

https://www.ndbc.noaa.gov/images/buoycam/W00A_2024_08_16_143...

FFT the image and/or remove the signal with a high pass filter and you would have a pretty good source of high frequency noise. The opposite of this is done for measuring waves, for the record.

lnwlebjel··on Researchers discover a new form of scientific fraud: 'sneaked references'
"The post caught the attention of several sleuths who are now the authors of the JASIST article. We used a scientific search engine to look for articles citing the initial article. Google Scholar found none, but Crossref and Dimensions did find references. The difference? Google Scholar is likely to mostly rely on the article's main text to extract the references appearing in the bibliography section, whereas Crossref and Dimensions use metadata provided by publishers."

So Google Scholar uses the text which is good. Then obvious solution is to go and look up where it has been cited, which would be easy to do with google scholar.

I don't know why anyone would jeopardize their career like this.
