I see some commenters claiming that plastic recycling is not a thing and that the concept have been pushed by big-plastic in (what I assume is) a greenwashing attempt.

While you can be as jaded as you want, it's always worth checking if your oppinion has any merit before posting it on an online forum for the rest of the internet to read.

Plastic recycling is a thing. It's more difficult than paper and metal (for instance), due to degradation of polymers and the difficulty of seperating different polymer types from one-another. It's less widespread than some companies would like you to believe (how many times haven't you read "this product was made by X% recycled plastic"?). Most plastic still ends up burned as fossile fuel substitute due to a lack of cost-effective recycling programs, but that does not mean the programs does not exist.

One success story is PET, which is found in drinking bottles. Polymer degration in PET can be repaired and countires with a PET recycling program usually seperates that plastic from other sources before entering a waste compound (such as through designated waste bins). When PET polymers are too damaged to make new bottles they are instead downcycled into synthetic fibers (similar to how degraded paper fibers are downcycled to toilet paper). If you want to read more on the process, why not have a look at Wikipedia?

Skip the sensational rewrite and read the original statement by van Rhijn et al., published in The Lancet: https://www.thelancet.com/journals/lancet/article/PIIS0140-6...

The authors lament the lack of research (and action) on treatment of fungal diseases, despite the introduction of a WHO focus group (WHO FPPL).

The paragraph in question which mentions a "silent pandemic" (AMR = antimicrobial resistance):

"The primary purpose of the WHO FPPL was to guide research, development, and public health action. Unfortunately, the desired effect has not yet been fully achieved as judged by the scope of the articles in The Lancet Series on AMR. Despite the clear need to prominently highlight fungal AMR, we express our disappointment that, even after many years of calling for action for this silent pandemic, only five sentences in one of the four Series papers are devoted to a few fungal pathogens."

I got curious and accessed the full paper. The five patterns (so called "R-indices") are:

R1. Subcortical atrophy • Stress-related gene set • Pregnancy

R2: MTL atrophy • Dementia • CN-MCI-dementia progression • Amyloid and tau • Cognitive dysfunction, mainly memory impairment • Birth weight

R3: Parieto-temporal atrophy • Dementia; schizophrenia;Parkinson’s; multiple sclerosis • MCI-dementia progression • Amyloid and tau • Cognitive dysfunction, mainlyin executive function • Pregnancy • Social/recreational activity

R4: Diffuse cortical atrophy • Multiple sclerosis • Smoking and alcohol consumption • Diet

R5: Perisylvian atrophy • Multi-organ chronic conditions • Psychological factors • Psychiatric diseases • Cardiovascular factors • WMH• Mortality risk • Smoking and alcohol consumption

These patterns were identified using a type of Deep Learning model, the paper then goes on studying the association between different factors (such as chronic diseases) and brain atrophy.

So in conclusion, this study have demonstrated how brain atrophy manifests itself in MRI brain scans and how we can "classify" them into one of five categories (or "patterns", if you like). The gain here is in diagnosis, imagine if a doctor could easily determine that a specific person exhibits " Type 2" atrophy? Much time, money and human suffering could be saved providing the patient with tailored treatment at the get-go.

I'm happy you found it helpful, medical studies don't pop up all too frequently here at HN so I try to assist when confusion arises.

Medical engineer here; I would suggest anyone whoms interest was caught by the title to read the Discussion, not Abstract. The authors have made good use of the section to broaden their conclusions, answering some of the questions I've observed in this thread.

For anyone starting to second-guess their relationship to sleep and caffeine; do note that this is a small-sample study and that more research is needed before any conclusions can be drawn with regards to the population at large.

EDIT: I'm not a medical professional (i.e a Doctor), I'm simply an engineer with domain knowledge in medicine. I am accustomed to reading studies like this. If anyone needs help interpreting the study, I'm happy to assist.

<pre><code> What do you mean by "not in working condition". I use it frequently and it just works. </code></pre> Some would disagree with that statement: https://github.com/smicallef/spiderfoot/issues

<pre><code> The little development on the project is probably due to it's age. </code></pre> How so? Even the most feature complete software is in need of regular maintenance to assure compatability with new versions of dependencies and OS. Such maintenance would appear to have stagnated since 2022, looking at the commit history.

Looking at the repo and some of the open issues, there have been little development activity over the last year and SpiderFoot is currently not in working condition.

That is too bad as it looks like quite a useful scanning tool, hopefully development picks back up.

It appears no-one have adressed the issue of wifi/bluetooth support, so I will weigh in.

I have installed Debian derivatives on both a Macbook Pro 2008 and a Macbook Air 2017 and had issues with bluetooth/wireless.

The solution was to identify the wireless chip through the terminal, download the specific DKMS module for that chip to a file on another computer, transfer the module over to the Macbook via USB, blacklist old module, install new, reboot.

This have worked flawlessly for me so far. If you want a tip on a beginner-friendly distro with decent Macbook support, try Pop!_Os.

Go the same route as Docker and Nextcloud perhaps? Offer professional services (hosting, personal support, advanced org-centered functions) at a fee to fund the open source part. You could split the software up into a "community" and a "professional" part with different licenses.

You won't get an answer on how Spotifys algorithm works for the same reason you won't get an answer on how any big-tech firm algorithm works; it's a proparitary software solution that is core to their business.

Can they be gamed? Tricked? Absolutely. Researchers spend a lot of time and resources trying to figure out how these algorithms work, once you're able to make an educated guess you can try manipulating it. If researchers do it, I see no reason (some) state actors wouldn't.

OP, please be transparent with the fact that this is self-promotion of your commercial software solution (OP is Hao Jiang, CEO of neuralrad). This should perhaps have been a "show HN" post, instead of what it is now.

Being active in the field of health informatics I went to the webpage (neuralrad.com) and was quite disappointed. There does not appear to be a whitepaper or similar which demonstrates the efficacy of your solution, nor outlining the limitations of the model. Some page navigation is broken (#hardware page comes to mind). I was also alarmed by the lack of HTTPS on the website.

This does not exactly ooze professionalism. I am especially critical of calling this software solution "leading" in its field without metrics. If you really belive in your product, please reconsider how you're marketing it.

Perhaps this is part of the "gig culture", do side projects have to generate a profit? If you feel overwhelmed, opening development up for others (as in, open sourcing it with whatever license you feel is appropiate) might just be what you're looking for. If the app is appreciated by a community, it will become practically self-promoting within whatever niche you've placed yourself in.

  DLRover makes the distributed training of large AI models easy, stable, fast and green

  DLRover can restore the training when the process fails without stopping the training job.

  In addition to fault tolerance, DLRover provides the flash checkpoint to save/load checkpoint in seconds.
I've personally never trained a model large enough to warrant the use of tools like DLRover, but I definetly see the intended usecase. I do however wonder if re-scheduling a task that failed due to OOM (one of the provided examples) won't just fail again due to OOM on another node.

I'm a stickler for using correct terms, one nitpick I have is the "green" descriptor. The repo does not ellaborate on how DLRover makes the process more "green", but I can only assume that they mean it helps with resource management, which in turn could make the process more energy efficient. If that is true, the authors might consider replacing "green" with "resource efficient".
