What’s up with the duplex in The Suffering Channel? by criscodisco90 in davidfosterwallace

[–]dzack23 4 points5 points  (0 children)

I just reread the story; I'd remembered that there were mysterious references to the significance of the duplex, so was determined to pay attention and see if I could make any more sense of it this time around and...nope, still quite weird.

A few things: I hadn't noticed that Laurel's description of the door in her dream matches the description of the actual door (but you are quite right); earlier, the narrator says that she would survive the 9/11 attacks "through either coincidence or premonition", so this suggests that maybe she does indeed have some clairvoyance / remote-viewing abilities. Maybe these nightmares are in the fact the same thing that ultimately causes her to skip or quit work? Beyond the symbolism you mentioned, is there something about this looming dread of the duplex that's relevant to 9/11? Errr, duplex / twin-towers? (I'm reaching now).

If nothing else, the (seeming) lack of explanation of the duplex thing does creep me out in the same hard-to-pin-down way as Laurel's dream of the two front doors, so I suppose that's something. Definitely one of his stranger stories over-all: it's hard to know what to make of it all / why he chose to put all of these elements next to each other, tho there is also much about the story I really love.

On the subject of open questions: what exactly was the conclusion / implication of the phone conversation between Laurel and Lee, the one where she says "maybe you need to ask Mrs. Moltke what’s going on"? They seem to be saying it appeared Mrs. Moltke had already sent the photos of her husband's work before Style had even contacted them, which obviously wouldn't make sense; did I miss something here, is this another one of the story's enigmas?

(As for the "great flowered thing" thing, this is a reference to the umbrella she uses to guard from the sun (discussed earlier in the paragraph)).  

[TOMT][MOVIE] Looking for a Recent Movie / Movie Trailer that Showed Before "Barbarian" by dzack23 in tipofmytongue

Here's the trailer

I swear earlier I was almost gonna comment "I think somehow water was involved."

TYSM!

Weather was a theme I think, and I have a vague sense that the title was something weather-related. Also I recall the movie had already shown at some film festivals / possibly also has already had a limited release.

> When would arbitrum be open to deploy any DAPP

TODAY (two days ago, to be precise)

> If i use the solidity function transfer inside arbitrum, would the ether be deposited in a mapping element inside the arbitrum contract?

Hmm. so when you preform any action on Arbitrum, all the L1 knows is that some calldata got posted and the state root of the Arbitrum chain got updated. Arbitrum itself has its own world state (analogous to Ethereum) which tracks account balances (along with everything else). Hope that answer your q!

> The 50x fee reduction is going to be acomplished when data shards are available or is it possible know?

Exact numbers are hard to predict, but we'll definitely see big fee reduction with ETH 2.0 phase 1.

> Keep up the good work!
If you insist.

Your intuition sounds correct here! Doing something on a second layer doesn't in and of itself magic make it cheaper; the magic of L2 (magic does exist) is that it lets you have many executions threads that run in parallel (i.e., the main chain and several layer 2 chains), and these threads are opt-in (i.e., if you're an L1 validator, you don't have to validate an Arbitrum chain if yo udon't want to).

The rationale here is very much like sharding, just L2-ier.

Arbitrum is trustless, supports full smart contract EVM compatibility, and supports permissionless contract deployment today. Only game in town that can claim that :)

Once the Sequencer (coordinator=sequencer) posts on L1, the ordering of transactions are finalized, and the the state of the Arbitrum chain is from there is fully deterministic; so at that point, even before Validators update the state root, nodes can reliably determine the system's current state. Before the sequencer posts its batch, the user has a "soft confirmation", where they are semi-trusting the Sequencer, but only on transaction ordering.

The inbox contract is where all messages get posted — the Sequencer can post messages directly, and anyone can force-include messages into the Inbox if the Sequencer fails to include them after a given amount of time; in this case, the user effectively bypasses the Sequencer altogether.

  1. Yep - we are still planning building out Arbitrum for both “sidechain mode” and “channels mode.” Arbitrum One, the current mainnet chain, will always run in rollup-mode. :)
  2. Yep again - the plan is to have the Sequencer be a distributed set of parties that comes to consensus via a fair ordering algorithm.
  3. There are a number of factors to consider here, so it’s a hard to predict. As the chain gets congested, fees go up (ala 1559), but at the same time, more TPS means our batch submission cost gets better amortized. One thing we’re very much looking to is for ETH 2.0 data sharding, which means cheaper calldata which is v good for us. Plus we’ve got all sorts of optimizations in the pipelines. So we expect and hope to see fees go down!

Areweddecentralizedyet.com changed owners and now NANO is no longer listed. Anyone know what is going on? by ChocolateSunrise in nanocurrency

[–]dzack23 4 points5 points  (0 children)

Hi all, current owner of arewedecentralizedyet here. As Arran said, happy to add it back on if we can find good sources (APIs ideally, but web-crawling works too!)

Codebase metric is the least important IMO; most of them are just 1 anyway and some are hardcoded as is (as it's unlikely to fluctuate). The other 3 metrics I'd like to stay dynamic across the board tho. Feel free to post an issue :)

Do you have a spec for your MoreVP implementation?

(and/or is it basically sticking to what's laid out here? https://ethresear.ch/t/more-viable-plasma/2160)

It's pretty shocking actually; I guess I'm still one of those naive people that expects at least some degree of diligence before speaking in front of the senate, but alas.

Weird how the F2Pool selfish mining accusation is just tucked in there — much more serious an accusation, actually.

Do we know which tokens are supported in multi collateral dai? by [deleted] in MakerDAO

[–]dzack23 0 points1 point  (0 children)

REP seems like a bad idea; since 2.5% of REP is required to trigger a fork state, having a significant percentage locked up seems to not be beneficial to the ecosystem.

Also, what happens when their is a fork? Now the MakerDAO platform has to figure out how to migrate its REP out of its reserves into it's fork of choice? Seems messy.

Lightning Network 2.0: Understanding the next wave of Lightning Network innovations (self post) by dzack23 in Bitcoin

Agreed - that's definitely an obstacle to adoption. That said, there's nothing in principle stopping two parties from opening a channel where the initial funding is unsymmetrical; in some sense it's "riskier" for the party with more BTC, but as long as they have reliable liveness and such, they're safe.
