Automerge: a new foundation for collaboration software
Просмотров 18 тыс.2 года назад
Local-first software is an effort to make collaboration software less dependent on cloud services, and Automerge is an open-source library for realising local-first software. In this talk I explain our motivation for creating Automerge, and map out 7 years worth of research projects that are feeding into this project. Recording of a talk given at the University of Cambridge SRG Seminars on 25 N...

My lockdown project for the last year has been to learn the piano. Thanks to my partner for teaching me. Here is my attempt at Scott Joplin's Maple Leaf Rag, with plenty of wrong notes - that's how you know it's played by human, not by computer.

Distributed Systems 1.1: Introduction
Amazing!!
What other viewpoint is there other than clients viewm does anything work or we just keep talking and finally say I never said it would work.
After watching many videos, I finally found the explanation of an understandable protocol given in a very understandable way. Thank you very, very, very much
Sounds like useless talk with no solution. There needs to be verification flow assuming failures and error correction built in. Just interseted in talking with no solution.Finally did the transaction commit or not? Looks like it goes on forever. Reinventing consistency Like a new wheel? My consistency is different from yours?😊 Is anybody using 2 phase commit? Nobody uses it?it feels like if the transaction is held so long as video, it is not feasible.
It is a gem 💎
i wondering about version vector, too. !!
Pretty much all this concepts are just confused on what to name an request standard. Let's call it RPC, no REST no gRPC, how does AJAX sound... It good that I now know the difference tho.
This video is so clear and informative. It answered most of the questions I had.
can we use this algorithm in wireless sensor networks?
What an excellent video - thank you!
For me the best course for DS. Thanks Martin
11:10 wow that's the ultimate definition of concurrency right there
Thank you for this amazing free series, you are the best.
Big fan of his thought process. I wish I could do phd under him.
I am little confused on your statement on "logical timstamps/lamport timestamps provides total order". if they provide total order why even bother about vector clocks? you clearly say that lamport timestamp cannot distinguish concurrent events so how can you call that a "total order"? Also when I put in "does lamport timestamp gives partial order or total order ?" in chatGPT it clearly says "partial order". What am I missing?
I have one doubt. In one of the slide , you mentioned ..in other parts of the computer science Synchronous and Asynchronous are used in other aspects or differently. Can someone please help me to understand that ? and great video series and thanks a lot Martin!
The moon is not actually made of cheese!
Immediately liked and shared. Golden content for computer science folks
Oh no it isn't!
The moon is made of cheese!
Hi Martin, thank you for the lecture. One question regarding quorum and linearizability. In your example of non-linearizable quorum, the write was asynchronously replicated, which can technically violate the quorum safety condition, as the write wasn't acknowledgement by a quorum of nodes. What if the quorum is used with synchronous replication, such that the write is not committed before receving such acknowledgement from the quorum. In that case, a read quorum will always find the most recent write. Any thougts?
Answering to myself: I figured out that the operations are happening concurrently, so client 1 is still pending an ack from the quorum.
Bizantine as the name come from bizantin (Greek and east europe).
this aged well
Wow, I didn't know Martin has a YT channel. Instant subscribe.
Great theme tune for distributed systems
Great theme tune for distributed systems
Big thanks
Excellent lectures but ads are really annoying
Thank you
You're not only a great author but also an amazing teacher. Thanks Martin.
u are the GOAT of DS!
Where Can I find first half of the course ?
Woow what a gem I found! Living in this day and age is amazing and gorgeous, thank you so much for uploading!
Thank you very much.

Glock. Genuinely meant block
Did you glock😢
I am sl confused rn
Something
Haha lol i made a funny
Honestly this is a really bad analogy to describe this problem.
I don't understand why at 09:41 you mentioned idempotencenl only for best-effort algo? All other algorithms have reliable network system model which can only be achieved with retry pattern. And if retry isnin place, then idempotence also should be, no?
Thank you so much for the perfect explanation
so interesting! thank you so much for posting this series : )
Sir, where is part one?
brilliant! thanks a lot for the content Martin!
Awesome video!
I don't understand why I am paying 2000 for a uni course as an international student when I get to learn all this sh🎉 here with much better quality
Great series for distributed systems.
how do we handle obtaining commit timestamp in a raft database without physical clock? just two phase commit?
why on slide 9 the leader need qurom to deliver while on slide 7 the follower can just commit?
because the leader is the only node that could decide which log entry is ready to be committed by checking if more than half of the nodes have already acknowledged this log entry (quorum).
ok seems slide 7 deliver logs up to leader, while slide 9 deliver the logs for the first time
