travisjefferyon Kafka without ZooKeeper

I'm not sure, I haven't heard of that happening before. I've asked my editor if she knows what's up. You can email me at tj at my HN username dot com if you want to follow up.

Awesome! Hope you enjoy reading the book and thanks for buying it.

travisjefferyon Kafka without ZooKeeper

Hey, I'm the author of Jocko. I've been working at Confluent the past four years.

I just finished writing a book that shows how to build similar distributed services from scratch, it walks though building a simple distributed commit log with built-in consensus and service discovery from nothing to deployment: https://pragprog.com/titles/tjgo/distributed-services-with-g...

travisjefferyon Building Clusters with Serf.io (and Fly.io)

People that are interested in this blog post will interested in a book I wrote: Distributed Services with Go (https://pragprog.com/titles/tjgo/distributed-services-with-g...). The book walks the reader through building a distributed event service from scratch that uses Serf as a library for its service discovery.

Magit is working on switching to libgit2 https://github.com/magit/magit/issues/2959 to fix this.

travisjefferyon Ask HN: What are some books where the reader learns by building projects?

Yeah I'm discussing with my editor now about when to put out the beta it'll be out either after we finish editing the chapter I just finished writing or the next one. So pretty soon. I hope to have the whole book finished by July but that's a bit more TBD up to how soon I finish writing the last few chapters.

Thanks!

I'm currently writing a book for PragProg called Building Distributed Services with Go (though it mostly applies to other languages too) that's walks you through building a distributed database from scratch. You can sign up on this mailing list to know when it's available: https://travisjeffery.us4.list-manage.com/subscribe?u=1e3ff7....

travisjefferyon Database Internals

I'm not doing it for the money. Writing a worthwhile book is about the least efficient way to make money.

travisjefferyon Database Internals

Yeah---each chapter begins with background on the chapter's topic, some theory, covers how and where you'd use what's we're talking about in the chapter and then we use it to build a part of the project we're building throughout the book. For example, in the consensus chapter we talk about what problems it solves and how you can use it in your projects,and then we implement Raft in the service for leader election and replication.

travisjefferyon Database Internals

Awesome. Hopefully within a month or two.

travisjefferyon Database Internals

Not sure, haven't gotten to that yet. Just from looking at the prices of other PragProg books somewhere around $21.95-24.95.

travisjefferyon Nine-year-old child to graduate university

I think the keyword is "typical." Which is probably true that the math is pretty basic at most universities and in most programs.

But you can go to schools like the University of Toronto, which is a strong math school and has very challenging programs like ASSPE1165 (https://fas.calendar.utoronto.ca/mathematics-specialist-scie...)

travisjefferyon I'll Take Pkg over Internal

Most popular languages do, it seems reasonable.

travisjefferyon I'll Take Pkg over Internal

First of all I think it's cool enneff read my post.

But pkg doesn't only make your import paths unwiedy. I'ts more like that's the only---or at least main---issue with pkg. But you get benefits from it that I talked about: consistent layout structure; know what directories are packages; separate your packages from examples, docs, etc. If pkg only made your import paths unwiedy then no one would use it.

travisjefferyon Habits of Expert Software Designers

Hey, I'm currently writing a book for PragProg that's going to announced soon. It's tentaively titled "Building Distributed Services with Go", and the Go part is secondary if it's not your language of choice. It guides you through building a distributed service from beginning to end. I don't have anything to point you to at the moment other than my mailing list and I'll let you know when the book is in beta: https://travisjeffery.us4.list-manage.com/subscribe?u=1e3ff7.... Thanks.

travisjefferyon A high-speed network driver written in C, Rust, Go, C#, Java

Here's a list of prominent Go infrastructure projects and by no means a complete list: Kubernetes, Docker, Etcd, Consul (and the rest of Hashicorp's projects), CockroachDB, Prometheus, TiDB. Maybe I'm just blind to C# but I don't remember coming across a single similar project that's written in C#.

travisjefferyon “Username or password is incorrect” is bullshit

You got it. You can be about security or UX. And when the accounts are public I'm especially in favor of taking advantage UX-wise. The issue's when both are half-assed.

travisjefferyon “Username or password is incorrect” is bullshit

This is a better argument, but rarely given. The issue is the accepted argument made for 'username or password is incorrect' is it's a best practice protecting the existence of accounts on sign ins, yet sign ups are ignored.

travisjefferyon “Username or password is incorrect” is bullshit

Correct. The UI message would always be the same, some variant of "email sent." Even if the account already existed and it wasn't actually a successful sign up of a new account.

travisjefferyon “Username or password is incorrect” is bullshit

Haha, that's cool with me.

travisjefferyon “Username or password is incorrect” is bullshit

Exactly. You got it.

travisjefferyon Jocko – Kafka implemented in Golang

First, I'm a big fan of yours. I was recently interviewed by Go Time and I talked about how awesome Redis is, what a good example it/you've been for open source projects, and how funny your v4 RC blog post was.

My goals for building Jocko to start:

1. Learn more about distributed systems to the point I could build one "What I cannot build, I do not understand." sort of thing. 2. Simplify running Kafka—so remove ZK, only need to install a binary, and so on 3. Maintain compatability—so people can just drop Jocko in, Kafka clients and anything else that uses Kafka's protocol works

After that, I have some ideas on things to do but am waiting to get feedback from people. For instance, I think the configuration around setting how much disk space topics use could be better.

I wrote the article.

The article includes git log -G"pattern". git log -S"string" it limited to a string.
