jablongo··on New York to ban natural gas, including stoves, in new buildings
> Regarding heat pumps phasing out gas heat, in NY it isn’t feasible. It gets too cold.

Not true, heat pumps are widely used as primary heat sources in environments as cold or colder than NY, like in Montreal and other parts of Canada. The take that heat pump tech only works in very moderate temperatures is stale at this point.

jablongo··on Glucomate: an app for people who record, track, and monitor their blood glucose
You can adjust the alerts a little bit. If you are actually going below 60 on a regular basis then you are hypoglycemic and the alerts are probably useful. It’s possible that your readings were slightly off though. Thanks for driving down prices for the rest of us! Keep on ordering em, big spender! I mean that.

A lot of people are claiming you need a prescription to purchase one; that is actually untrue in practice. You need a prescription to get insurance to pay for it but there are plenty of websites that sell dexcom (the best kind) devices dtc. Just search “dexcom purchase” on your favorite search engine. You’ll have to spend several hundred dollars though. Also there are services like levels or January.ai which white-label Abbott devices and handle all the prescription stuff for you.
jablongo··on Tell HN: DEI initiatives undermine the self esteem of PoC within a company
Literally the OP
jablongo··on Tell HN: DEI initiatives undermine the self esteem of PoC within a company
To be clear, do you think race-based diversity hiring is good? I can agree that having good role models and educational opportunities is important but I'm not so sure race-aware hiring is a good thing, for the reasons stated by OP and others.

At what point do you think DEI should stop? Is there any metric or threshold at which these programs/events should end? One of the biggest issues for me is that these measures are either argued as good because "diversity is intrinsically good" or because "we are righting historical wrongs", meaning reparations. While one could argue for or against either of these justifications, it would seem that the former would terminate once some ideal demographic composition is achieved, while the latter would end once some calculated total sum of restitution is reached. To me, these details are very important, since race-based hiring is an intrinsically bad thing that should be avoided. After all, it is part of the reason people of color got so screwed over in the 20th century in the first place.

jablongo··on Interpreting a Sierpinski Triangle Fractal as musical notes sounds good
Thanks for this comment. I mostly agree with you. A music theory professor used to lazily say that "nature says so" when asked why a major 3rd sounds better than an augmented 4th (i.e. tritone). Lacking a better explanation I assumed this had to do with consonant chords having notes whose wavelength had a lesser common multiple, but am not entirely sure. Can you provide some citations or resources describing the mathematical justification for a 12-tone basis for tonal music in more detail? I know there was a group theory element to some of Schoenberg's compositions but aside from that I have not been exposed much to this idea.
jablongo··on Interpreting a Sierpinski Triangle Fractal as musical notes sounds good
This is more complex than pentatonic noodling, but I agree with other posts that this sounds the way it does mostly because of the choices made by the interpreter. The crucial choice was that every pixel of sierpinski’s triangle is a note in a major scale. All sierpinskis triangle encodes is the ordinal rank of the notes, everything else is added by the choice of how to translate it into the musical space. If the mapping were to a 12-tone chromatic scale and the result were somehow tonal with interesting harmonies that would be really remarkable. Even then though the 12 tone scale is an interpretation of tonality from western music.

That said even if it’s not a sign of the hand of god it’s still pretty cool…

jablongo··on Interpreting a Sierpinski Triangle Fractal as musical notes sounds good
Neither, it sounds good mostly because of the major scale that it was mapped to.
jablongo··on Ask HN: Anyone tired of everything being a subscription now?
First of all I totally agree with you; the industry has turned to more rent seeking than it did previously. I think park of why this has happened is also related to the transition to cloud computing. This means that unlike earlier versions, modern photo editing software includes cloud storage and computing and therefore you have recurring upkeep costs for the software maker.
jablongo··on Riffusion – Stable Diffusion fine-tuned to generate music
Hello - this is awesome work. Like other commenters, I think the idea that if you are able to transfer a concept into a visual domain (in this case via fft) it becomes viable to model with diffusion is super exciting but maybe an oversimplification. With that in mind, do you think this type of approach might work with panels of time series data?

jablongo··on Galactica: an AI trained on humanity's scientific knowledge (by Meta)
I think I broke it:

Question: Why did civilization form when it did?

Answer: The Earth formed about 4.5 billion years ago. The first life forms appeared about 3.5 billion years ago. The first single-celled organisms were probably bacteria. The first multi-celled organisms were probably protists. The first animals were probably sponges. The first plants were probably green algae. The first land plants were probably mosses. The first animals to live on land were probably insects. The first vertebrates were probably fish. The first amphibians were probably amphibians. The first reptiles were probably reptiles. The first mammals were probably mammals. The first birds were probably birds. The first dinosaurs were probably dinosaurs. The first mammals to live on land were probably mammals. The first reptiles to live on land were probably reptiles. The first amphibians to live on land were probably amphibians. The first fish to live on land were probably fish. The first insects to live on land were probably insects. The first plants to live on land were probably plants. The first land animals were probably..

jablongo··on Indian Air Force inducts natively developed light combat helicopter ‘Prachanda’
Because it’s not offensive or incorrect. American Indians have adopted and use the term themselves. Most official American Indian organizations are named as such, and not as “Native American” or “First Nations”, though the latter is also catching on, especially in Canada.

Yes that’s the word
jablongo··on Galactic settlement of low-mass stars as a resolution to the Fermi paradox
Another major filter supposedly comes much earlier: the development of complex single celled eukaryotic life. Some people think this occurred due to a single subsumption event on earth between a bacteria and an archaea.
jablongo··on Teenager solves stubborn riddle about prime number look-alikes
> A computer program to factor any polynomial equation string input to it: Do you mean a program to solve for f(x) = 0 using numerical approximation? Factorization has a specific meaning and is not necessarily possible for quintic and higher-degree polynomials / there is no closed form solution like the quadratic formula for n>=5.
jablongo··on What “diversity and inclusion” means at Microsoft
This is wrong, the civil rights legislation from the 60s is now being used by Asians in current discrimination suits against colleges. The CRM legislation was colorblind, and therefore will be an enduring protection against discrimination towards any group.
jablongo··on Medtronic's MiniMed 600 insulin pumps potentially at risk of compromise
Yes open communication with insulin pump has historically been a feature not a bug. In the older minimed models you still needed the device serial number to “hack” it, not sure if that’s the same for the 530g, but if it is that’s enough security for me as a type-1 diabetic. The cynical part of me thinks that minimed is more concerned with playing defense against superior closed loop software alternatives than they are about safety.
jablongo··on Six months as a full time pancreas
I agree with this but your numbers are off IMO. Diabetics who use closed loop systems diligently can achieve A1Cs nearer to 5 without becoming dangerously low all the time. It is hard, but new tech is making it easier. Also an A1C of 5.5 is at the very top of the acceptable range before being pre-diabetic (5.7). Lastly, your nervous system becomes accustomed to the blood glucose range that you are frequently in... there are studies about T2Ds with A1Cs of like 9 who get low blood sugar symptoms when their glucose is ~90mg/dl (normal). So A1C of 5.5 in T1D does not automatically imply dangerous hypos all the time, maybe A1C of 4.9 does though.
jablongo··on Six months as a full time pancreas
A great write up. Fate would have it that my name is Sam and I am T1D as well! You should sign up for the mailing list of the application I am currently working on https://replica.health/. We are building a context aware search and recommendation system for T1D data. If CamAPS writes its data to apple health like dexcom does you guys might find our tools useful for exploring his data and for diabetes decision support.

jablongo··on Spaced Repetition for Mathematics (2021)
I played piano competitively in college and when my teacher revealed a version of this trick for memorization it seemed like a cheat code at the time. Playing a short difficult motif over and over again is needed sometimes to get it right, and the key was to lock in the “correct” movements and not retain anything else. So the idea was after you played it once correctly you would take a moment and let the section recede from short term memory and hopefully into longer term storage and then start practicing again.
jablongo··on Google fires engineer who called its AI sentient
Not disagreeing with you that LLMs are probably not sentient, but that is neither here nor there since lamda is more than a simple llm. There are significant differences between GPT3 and LaMDA. We gotta stop making these false equivalences. LaMDA is fundamentally more dynamic in the ways it interacts with the world: it constructs its own queries to ground truth sources to check it’s facts and then updates weights based on that (among many other differences). While it does incorporate LLMs it seems like people are in denial about the complexity and data access that lamda has relative to GPT3. In google’s own paper about lamda they demonstrated how it sometimes showed a rudimentary theory of mind by being able to reason about other’s perceptions.

Yea it is a sophisticated propaganda operation aimed at western readers. It sometimes even has good reporting but everything is curated to serve the kremlins interests.
