substack what does it look like to download/seed with hyperdrive from the command-line?

substack i am a bit lost in all the changes

substack i see there is some daemon now. is there an analog to ipfs daemon/ipfs add?

Dat

@dat_project_twitter

substack i click on links and there are deprecation notices for example on hyperdrive-daemon-client which links me to hyperspace, but that appears to be another daemon

Dat

@dat_project_twitter

cblgh the only thing i have managed to use and download stuff is dat-store, which also is a daemon

Zach Dwiel

@dwiel

should I be able to access all of the versions of the files ever added to a dat? I am trying to use the dat command line --http option with a ?version=xyz in the address and it is working on some files, but not on recently changed files. On recently changed files the http server hangs the request and never returns any data

Zach Dwiel

@dwiel

do I need to be running a dat cli with non-standard command line switches for it to record all versions?

Zach Dwiel

@dwiel

alternatively, is there another service/tool I can use to record the history and not just the most recent version of each file?

How to allow permissions for the shared content? For example, content A can be accessed only certain clients and content B can be accessed by only certain clients etc. Is there a way to achieve this?

Elon_Sat0shi hello

Dat

@dat_project_twitter

Elon_Sat0shi Did you hear about youtube-dl being DCMA'd?

Dat

@dat_project_twitter

Elon_Sat0shi Ok, so how do I add new files/changes from the dat CLI program?

Dat

@dat_project_twitter

Elon_Sat0shi Why doesn't dat share any files unless I create a dat.json?

Dat

@dat_project_twitter

Elon_Sat0shi Unless I create a dat.json when I try to sync it syncs an empty archive

Elon_Sat0shi But if I do create a dat.json it syncs the one file I have in my test folder

Elon_Sat0shi It still syncs that file after I delete dat.json

Elon_Sat0shi But if I don't create dat.json it syncs an empty archive

Elon_Sat0shi I don't get it

timgoeller Heya, is there some way to access the dat discourse? It seems to be offline

Is anyone watching the issues' queue for dat-sdk? I'm having an issue or two :)

@RangerMauve is mainly working on the dat-sdk stuff, so I guess they would be watching the issues

hello all,

I been trying to build 1.0.0-prerelease-7 on windows from source but it always throws me error ,

on windows 64 bit i have, nodejs -12.0.0 , microsoft visual studio 2015, i have used windows-build-tools , i ahve follwed all the prerequisite - :
In Windows, you'll need to install Python 2.7, Visual Studio 2015 or 2017, and Git. (You might try windows-build-tools.) Then run:

npm config set python c:/python27
npm config set msvs_version 2015
npm install -g node-gyp
npm install -g gulp

I am getting error while doing
npm run burnthemall

How to allow permissions for the shared content?

@KrishnaPG - several teams work on this problem. Pushpin by Ink and Switch solved it in one way. Our team plans to work on this quite soon. One thing you need to ask yourself, what is content's granularity. Is it at the level of the whole hypercore, then it is much easier. If it is on the level of individual data elements, like key-value in Hypertrie / Hyperbee or a file in Hyperdrive, then it is much harder. Revocations of permissions is another issue. Separate dimension is what type of permissions. I assume read only. But for the multi-writer data structures, they may extend further, including partial permissions, if you were given permission to write, can you give any permissions to others?

I am sorry to repeat my message, but I was told the link to the Discord has expired.

So, this chat is staying, no worries about that, but we added an additional communication on the DIscord where we can have multiple chat rooms and better mobile app.

Plan is to migrate to Cabal or similar sistem once it's ready ready, but until then, feel free to find Dat ecosystem also on Discord https://discord.gg/jukapbdep5

Hi guys.

For our blockchain project we need to choose the right storage solution based on Hyperprotocol. Our main requirement is that it has to work as a Real Time Database, namely, be fast and performant.
There're other requirements too.

I suppose that it could be Sonar, Hyperswarm, or anything else

Who could give us a few pointers, or a paid consultation?

nettle is a cryptographic signature a superset of a checksum? like, is there benefit in including a sha256 hash of a binary if you have a signature for it?

Dat

@dat_project_twitter

substack a signature proves authorship by a particular party but a hash proves file contents

nettle substack: but if you altered the file wouldn't the signature become invalid?

substack you could publish a new version with a new signature, i mean

substack but yes that signature would be invalid if the file changed
