Absolutely, loss of deep sleep is associated with a ton of aging related cognitive decline. There's a number of startups experimenting with techniques to enhance deep sleep in the elderly atm (timed audio clicks, electrical stimulation

Melatonin has a short half life (~1h), that's why melatonin receptor agonists [1] are a thing. So just mechanistically it's unlikely to help with sleep maintenance. Do you wake up after 5.5h at a consistent time of the day and the

I'm pretty sure at this point I have familial advanced sleep phase syndrome of an unknown genetic etiology [1]. Wake up stupid early in the morning, get drowsy very early in the evenings etc. For a long time due to social pressure&#x2F

FWIW QUIC enforces TLS 1.3 and modern crypto. A lot smaller surface area and far fewer foot-guns. Combined with memory safe TLS implementations in Go and Rust I think it's fair to say things have changed since the heartbleed days.

How did you work around WireGuard's encryption and multiqueue bottlenecks? Jumbo frames? 25G is a lot for WireGuard [1]. 1. https://www.youtube.com/watch?v=oXhNVj80Z8A

Now that's an interesting, and wild, idea. I don't believe you could implement RFC 9484 directly in the browser (missing capsule apis would make upgrading the connection not possible). Though WebTransport does support datagrams so

I've recently spent a bunch of time working on a mesh networking project that employs CONNECT-IP over QUIC [1]. There's a lot of benefits for sure, mTLS being a huge one (particularly when combined with ACME). For general purpose,

For TCP streams syscall overhead isn't a big issue really, you can easily transfer large chunks of data in each write(). If you have TCP segmentation offload available you'll have no serious issues pushing 100gbit/s. Also if

It's mind-blowing to think XDR / ONC RPC V2 were products of the 1980s, and that sitting here nearly forty years later we are discussing the same problem space. Probably the biggest challenge with something like XDR is it's v

Now that's an interesting thought, I wonder if you could use a modified subset of TypeScript to create a IDL/DDL for JSON-RPC. Then compile that schema into implementations for various target languages.

I'd say the success of REST kind of proves that's something that for the most part can be worked around. Often comes down to the JSON codec itself, many codecs will allow unmarshalling/marshalling fields straight into long in

To be honest I kind of find myself drifting away from gRPC/protobuf in my recent projects. I love the idea of an IDL for describing APIs and a great compiler/codegen (protoc) but there's just soo many idiosyncrasies baked int

The German pension system is completely insane. There is no fund backing it, and disbursements already exceed contributions to the tune of 127B EUR per year (which is subsidized from the general budget) and the gap is only growing. Probably

I think this is the fundamental cultural difference between countries like the USA (and Australia) vs most of the EU. Folks here expect and trust the state to provide for the future, private provisions are easily dismissed as unnecessary. A

Yep they're the technology equivalent of a discount supermarket. Everything is commoditized to the extreme. Breath of fresh air in the modern cloud era tbh.

This is typical of Hetzner, if a product SKU is losing money they very quickly make changes, even going as far as to discontinue the product entirely (eg. GPU servers). They definitely don't seem to be a fan of loss leaders. I'm g

Yeh nah mate, I'd recommend moving to the middle of nowhere in Aus over a low cost region in the EU. You really want to be in a long term growth environment (even if you're starting off at the bottom) than some decaying, economica

You can already do this trivially with Linux vcan[1] so I don't buy this argument. I think the bigger factor is that innovation in the CAN ecosystem has been lagging behind Ethernet for decades now. Only reason it's had such stayi

It's a good thing we invented video compression and hardware codecs/encoders a long time ago. What you'll actually be sending is a high bitrate mpeg stream, probably 54Mbps or thereabouts, you could probably fit 50x camera st

Measuring at a single point in time is so inaccurate due to things as simple as circadian variation of blood pressure (morning surge, night time dipping, etc). Not to mention acute stressors, arm positions etc. It's hard to put any wei

Dietary fiber is well established to reduce the risk of Colorectal cancer [1]. If there's one thing that's seriously missing from an ultra-processed diet it's fiber. Almost certainly multifactorial though. 1. https:/&#x

Similar experience here, was WGS and running the results against ClinVar came up empty[1] for known disease causing variants. Was not expecting that at all. But I totally think this is more an absence of information than anything else. We a
