There are more major issues I would hope the article authors would correct. I know, not likely to happen. Here's a few notes to think about -

> The analysed star cluster IRS 13 is located 0.1 light years from the centre of our galaxy. This is very close in astronomical terms, but would still require travelling from one end of our solar system to the other twenty times to cover the distance.

If the "one end to the other" metric, at best, is 2 x 100,000 AU [1] if it means the edge of the Oort cloud. That's about 3.16 light-years.

But GCIRS 13E appears to be 26,000 light-years away. Hint: 3.16 light-years x 20 is not even close to 26,000 light-years.

The article never mentions any theories on the formation of these intermediate-mass black holes, or why confirming the existence of one in our own galaxy would be meaningful science.

> But GCIRS 13E appears to be 26,000 light-years away. Hint: 3.16 light-years x 20 is not even close to 26,000 light-years.

The article isn't describing how far away from Earth IRS 13 is. It's describing how far from the galactic center it is (0.1 light-year, not 26,000 light-years).

To help narrow down what the author is referring to by "one end of our solar system to the other", one can divide 0.1 light-year by 20 to get 0.005 light-year, which is about 316 AU. I'm going to assume th⁹at the reference is to the heliosphere, then, since it's apparently about 300 AU across:

"The Sun's stellar-wind bubble, the heliosphere, a region of space dominated by the Sun, has its boundary at the termination shock. Based on the Sun's peculiar motion relative to the local standard of rest, this boundary is roughly 80–100 AU from the Sun upwind of the interstellar medium and roughly 200 AU from the Sun downwind."[1]

My understanding is that the formation of intermediate mass black holes is pretty mysterious. In principle you could get those and the supermassive from stellar mass black holes colliding but in practice it takes more time than they’ve had.

I kind of admired the brevity.

Sure, nobody agrees on what the strict definition of great is. I don't think it's reasonable to argue that a blog post titled "My pet theory..." doesn't achieve the minimum word count.

Go back and read the HN thread [1] that was the impetus. Now TFA exists within a lot more words to train an LLM on.

Why not attempt to triangulate what this particular piece of software might look like, if it was the best it could be?

Most likely something like Qualcomm (or another similar vendor) saying that they refuse to provide the vendor kernel, and will just ship Windows on ARM instead.



> "supporting Linux on laptops with Windows on Snapdragon"

blinks rapidly

edit: I guess if you squint really hard to read "Windows" as "PC-style operating systems" (or "general purpose computing") it makes sense?


Hmm, maybe they are referring to a specific branding used on recent models, e.g. a "Windows on Snapdragon" sticker similar to "Windows 8 Ready" and stuff.

Linux laptops still tend to be special order or niche brands, but there is nice positive traction in that space.


This is quintessential MSFT. I have absolutely less than zero doubt that there is a informal/formal agreement that they're called such. They always pull this crap. And then their OEMs realize later that the "Windows 8 Ready" sticker is almost more of a pariah.


It's an interesting challenge because the device is nominally "under ISP control" but any device located in a customer's home is under the physical control of the customer. The mistrust between the ISP and the customer leads to "trusted" devices where the firmware, including the backup, can be overwritten by the ISP, but then cannot recover if it gets corrupted. And believe me, the corrupt firmware scenario happens a lot due to incompetence.

This is getting attention because it wasn't incompetence this time.

But how does blank, unprovisioned equipment discover a path to its provisioning server? Especially in light of the new "trusted" push, this is an arms race in a market segment such as routers where there isn't any money for high end solutions - only the cheapest option is even considered.

tl;dr: a social and economic problem, likely can't be fixed with a purely technical solution


This was years ago, but I remember getting cable service activated somewhere in Florida with Bright House. I handed the cable guy some ancient motorola cable modem I had found at a discount store. The guy took one look at it and said "look dude, if you hacked this thing to get around bandwidth caps it is your problem if you get caught". I guess apparently that particular modem was pretty easy to modify


Maybe it already was modified!


Technical solution: customer treats ISP's modem/router as untrusted, and daisy chains their own router after it. Neither malware nor ISP's shenanigans can access the inner network.


That’s what I do. Also makes changing providers straightforward (though last time I needed to set up some custom VLAN stuff on my router but didn’t have to fumble with any wifi config).


Yes, it was 48 bits virtual but Intel is starting to introduce SKUs with support for 57 bits of virtual address space:

I mean, Microsoft pays him a regular paycheck. I think you're moving the goalpost quite a bit to ask that the community accept anyone's contributions until solid proof of malicious intent is shown.

Are you prepared to accept my contribution? I sign my name "JiaT57notThatJiaTan"


I'm not moving any goalposts, you're saying someone with decades of open source kernel development and a solid reputation is no longer trustworthy because of who now signs that paycheque. That's just nonsense, and has nothing to do with the scenario you posed.


HN Guidelines Checklist:

   [ ] When disagreeing, please reply to the argument instead of calling names. For example, arguing with "nonsense" and "has nothing to do with the scenario" detract from HN
   [ ] Comments should get more thoughtful and substantive, not less, as a topic gets more divisive. Avoid saying "I'm not ___" in a reflexive way
   [ ] Please don't use Hacker News for political or ideological battle. That tramples curiosity such as for Lenart Poettering's "a solid reputation"

Inertia causes the sensor in the accelerometer to read nonzero.

Meta: let's stop arguing what might happen, and do the experiment!


> Inertia causes the sensor in the accelerometer to read nonzero.

This can't be right, because an object moving solely under gravity is moving solely under its own inertia, but an accelerometer attached to it reads zero.

> do the experiment!

Do what experiment? Experiments showing that accelerometers attached to objects moving solely under gravity read zero, while objects subjected to non-gravitational forces read nonzero, have been done.


> it does not rely on installed Python as in GN case as other tools.

I'm curious if you can expand on how you're using python, and what pain points you have there? I think python 3.9 was one for us but not too bad.


The researchers are careful to not say that. (Remember the big uproar around LK-99 superconductors?)

To my lay eyes, it looks like they have excellent research showing a pathway used for the regulation of the "innate immune response," which is the fast-acting first response to pathogens. And they saw some strong evidence but not a sure proof that Lupus may be caused by the loss of regulation due to a mutation.

To show that it's more than a nice coincidence, I think they'd take careful steps: maybe a CRISPR therapy trial, maybe a drug trial specifically aiming to regulate this part of the immune system through other careful means. Lots of clinical trials.

To families affected by Lupus this might seem painfully slow. I'm optimistic though: this sounds like the kind of solid research to uncover the exact functioning of the human immune system.


Converting atmospheric CO2 into fuels could contribute to this effort. But bacterial and plant-based fuel production may still be more economical and produce fewer overall emissions than even a solar array and a carbon capture plant.


Converting atmospheric CO2 into hydrocarbon fuels requires hydrogen as an input, so it'd probably be easier to just store the hydrogen directly. Right now, almost all hydrogen is produced through steam reformation [1] which emits CO2. Electrolysis is inefficient and corrosion of electrodes makes it expensive and hard to scale. Capturing atmospheric CO2 is similarly difficult. Carbon Dioxide is at very low concentrations in the atmosphere so it takes a really long time to sequester meaningful amounts of it. Similar issue with biomass: it produces energy very slowly and doesn't have the scale required.

There's a reason why plans for a primarily renewable grid assume that compressed air, synthetic ammonia, giant flywheels, or something else will provide storage for orders of magnitude cheaper than batteries: because existing storage systems aren't capable of meeting the storage demands of intermittent generation. Will one of these systems deliver a storage breakthrough? Maybe. But it's not wise to bet the future of your electrical grid on a technological breakthrough that hasn't happened yet.
