THIS.

Helping to put all the bullets in net neutrality...

Pathway to even greater corporatization and splintering of the internet?

Replacing public RIRs with private organizations, securely routing between each other..

How do I peer with the big corps in a SCION world?

Security and privacy are already addressed by things like transport layer encryption, so SCION doesn't really enable a more secure internet, it enables more (largely corporate) control


First of all, at this point, SCION is not here to replace BGP. It's here to provide a more secure way of interconnecting ASes for critical infrastructure applications (finance, defense, government, etc..) that allows path selection and verification over multiple-ISPs. It can for example, be seen as an alternative to MPLS but offering more capability.

SCION also offers more protection against DDoS attacks and other outages thanks to its multi-path routing capabilities and ability to failover quicker than BGP as it builds and stores its path knowledge in advance.

You do so by joining an ISD (Isolation Domain) and inheriting TRC (Trust Root Configuration).

Much critical infrastructure is still reliant on leased lines or MPLS which is expensive and reliant on a single ISP which often reduces resilience. It often also requires assurances about where its traffic is being forwarded (e.g. through particular countries or regions) which is difficult or impossible with BGP. SCION can instead provide these assurances over the commodity Internet provided by multiple ISPs, by being able to verify paths and allowing packet senders to control how packets should be routed given the available path options.

ISDs are typically for specific use cases (e.g. Swiss Secure Finance Network) where strong assurances are needed for where traffic is sent, but ISDs can decide admission criteria for themselves and how they wish to communicate with other ISDs and the rest of the Internet.

Think of the power grid for example. Putting power plants on the internet is probably a bad idea. A better idea is to interconnect power plants through multiple ISPs over a SCION ISD. Less expensive than leased lines or MPLS, and more flexible.


Storage costs less to manufacture and power than RAM. You are starting from a premise and making up a future where it's true, ignoring the realities of physics in the process.

I have a > 75ft service loop on a 48-count underground burial fiber from the street.

Try playing the Monolopy board game, you'll answer your own question.

+1, but it's not a small nitpick, principle of least privilege should be applied here.

+1 I do the same (and when I don't, I can feel the difference, which is generally very unpleasant).


That sounds like great family teamwork. I wish my partner would entertain changing their diet to accommodate this (I've asked). I imagine the challenges of life are slightly more tractable when you genuinely deal with serious adversity as a family unit.

I understand it means an extra burden for all; but to me, voluntarily doing something challenging together for a family members' benefit seems preferable to facing each adversity largely independently.

As an aside, while likely much better than uncontrolled, 6-7% A1C still seems on the high end for lifelong. You probably already know this, but exercise immediately after carbohydrate consumption can also help - e.g. family walk after dinner (another thing my partner isn't interested in)


Although it's possible for someone with type 1 to have an A1C below 6%, it's very difficult. I've known a few people like that, and they are all super users. It's also going to depend somewhat on the lab running the A1C test, personal biology (A1c is not only affected by blood glucose levels) etc. 6-6.5% is superb control! Parent should be very proud. 6.5-7% is still very good, I haven't looked at the distribution of A1c's for T1D recently, but that would be much better than median which I think is above 8%.

Especially with kids, it's difficult since you don't control how much they decide to eat making pre-bolusing meals challenging (part of why reducing carbs tends to be helpful for people is it reduces the need to pre-bolus and makes it less risky since you need less up front meal insulin).


I didn't mean to say it's not superb control for someone with T1D, only that there are likely still some negative health consequences at 6-7%, and that exercise after carbohydrates is one mechanism of potentially getting some additional marginal improvement.


This is good advice for pre-diabetics and type 2 diabetics but in type 1 diabetes exercise after meal often makes things worse. It makes insulin dosing less predictable.


We changed the entire family diet in part to help him not develop any complexes around food.

We would like to get him in the 5's, and I believe we'll get there. He was below 6.5% every checkup so far except the most recent one.

Between honeymooning and growth hormones, it's difficult to keep him in range from 10pm to 3am, while also not triggering a low after his stomach is empty.


Right, using stenography to encode some parity bits into an image so that lost information can be reconstructed seems like an obvious approach - all sorts of approaches you could use, akin to FEC. Haven't looked at your site yet, will be interested to see what you've built :)

Edit: I checked it out, nice, I like the lower res stenography approach, can work very nicely with good upscaling filters - gave it a star :)


steganography — stenography is courtroom transcription


People protect their secrets from stenographers with steganography.


It's not the async part, it's the not invoking the function part - io_uring replaces syscalls with producer consumer ring buffers.
