All the easy stuff that can | be done in 6-12 months has already been done. Anything worth | doing today is going to take a minimum of 1-2 years of R&D | unless it's nothing more than a packaging and polish/branding | of something already in existence. | dangoor wrote: | > This mentality that things either flip instantly to mass | adoption or are "old" needs to die. | | That's honestly not where I'm coming from, though. I think | Dat is a cool project and I've been aware of it from, likely, | close to the beginning. The scale between "new" and "old" is | not binary, nor is it necessarily related to "mass adoption". | There are people who still treat React as though it's "the | new hotness", despite the fact that it's been out for 6 years | and is widely adopted. | | I'll grant that different people will have different | thresholds for what they see as "new". I just personally | think Dat has gone beyond "new" and is in a phase of | maturation. It's even got a browser with deep support! | dang wrote: | We can take 'new' out of the title above, though I'm reminded | of a second-hand clothing store in my home town which used to | be called "New 2 You". | dangoor wrote: | Yeah, thanks! I'm totally on board with this link being here | and would love for more people to learn about Dat. | Already__Taken wrote: | Wouldn't a protocol like this be a killer feature in the next | package manager to solve problems npm had? Then you've just got a | discoverability issue without the whole infrastructure headache | on top to maintain. | rzzzt wrote: | "How Dat Works" linked from the page is still a great | visualization of all the bits that make up the protocol: | | - https://datprotocol.github.io/how-dat-works/ | | - https://news.ycombinator.com/item?id=20363813 | dang wrote: | Also https://news.ycombinator.com/item?id=20811936, a related | project from 2019. | JakeAl wrote: | Kind of stagnant, but I liked the IDEA of what was being done | with the Beaker Browser using the DAT protocol to run a self- | hosted P2P web. I just wish someone would take the project to | completion/usability. It would really disrupt things. | https://beakerbrowser.com | Taek wrote: | Skynet is a new protocol that has been working on something | like this.

It's going | to be a lot better! | https://github.com/beakerbrowser/beaker/pull/1435 | pfraze wrote: | We decided to take a year to go heads down and rework a lot of | stuff, so we did get publicly stagnant but we're fulltime on | the next version and should release a public beta soon. I tweet | a lot about our progress if you can sort through my sillier | tweets (@pfrazee). | | Past year has had a lot of improvements | | - Protocol moved to a hole-punching DHT for peer discovery | (hyperswarm). | | - Protocol now scales # of writes and # of files much better. | We were able to put a Wikipedia export, which is millions of | files in 2 flat dirs, into a single "drive" and get good read | performance. This performance bump came from an indexing | structure that's built into every log entry (hypertrie). | | - Protocol now supports "mounting" which is a way to basically | symlink drives onto each other. Good composition tool, esp | useful for mounting deps in a /vendor directory. | | - Browser now has a builtin editor that splits the screen for | live editing. Feels similar to hackmd. | | - Browser added a bash-like terminal for working with the | protocol's filespace. It's glued to the current page so you can | drive around the web using `cd`. | | - Browser added a basic identity system. Every user has a | profile site that's created automatically and maintains an | address book of other users. | | - We built out application tooling a fair amount. It's fairly | easy to build multi-user apps now, where previously it was a | bit of rocket surgery. | | Some of the year was spent prototyping ideas and throwing them | away as well. A bit inefficient, but helped us learn. | koeng wrote: | I've been thinking of deploying dat for Nanopore DNA | sequencing, but recall something about dat not being great at | handling that kind of data. | | Does the newest version of dat handle large files well | (10gb)? Does it handle tons of files nested in a few | directories well? Are there any issues I should know about | there? | | What is the command line support like for multi-writer? | | Do you have any metrics for how much Dat is currently being | used? | | Thanks! | pfraze wrote: | > Does the newest version of dat handle large files well | (10gb)? | | Large files work fine but currently any change to a file | rewrites it in its entirety. That will mean history will be | large until the GC kicks in, and any file that's modified | has to be redownloaded in its entirety. | | The team spent a fair amount of time looking at a solution | to partial file-updates which works like inodes. They | ultimately decided it was too difficult to pull off for | now. | | > Does it handle tons of files nested in a few directories | well? | | Yep, no issues there | | > What is the command line support like for multi-writer? | | We're still deciding on how to handle multi-writer. It's a | priority for us after the upcoming stable release. | | > Do you have any metrics for how much Dat is currently | being used? | | Nothing concrete atm. If I had to guess, it'd be no more | than 1k. | karissa wrote: | > Does the newest version of dat handle large files well | (10gb)? | | I'd be curious if anyone wanted to try it ;) https://gith | ub.com/mafintosh/hyperdrive/blob/master/index.js... | | > What is the command line support like for multi-writer? | | There is an experimental multiwriter CLI using hyperdrive | and kappa-db (github.com/kappa-db) | | https://cobox.cloud | grng3r wrote: | I've been reading about dat and doing some basic projects for | about a year in my spare time, stagnating a bit lately as am | finishing my degree.
