    14: TIL database connections aren't cheap

    A background job should be a function. So, putting more things in it is always a good idea! Sean announced that he shipped background jobs for crates.io. It's been in production for more than two weeks, and no issues have been reported. It's made life much easier because he no longer needs to spend time manually cleaning or cloning the index before changing a config bar. Now, he's working on librafying "Swirl." Also, Sam expressed frustration with his decision to use heredocs and block local variables in his Ruby autoformatter (Rubyfmt) - big mistake that caused big problems.

    13: "As much time as I can without reading C" with James Coglan

    Do you use Git practically every day, but have no idea how to implement it? Need a more accessible and easier way than reading original source code to understand how it works? Want to know how to rebuild Git in a high-level language to learn the concepts involved? Sam talks to James Coglan, who wrote the book, Building Git. It teaches readers how to rebuild Git in Ruby and helps them develop debugging skills. Also, James shares his thoughts on Sam’s Ruby autoformatter (Rubyfmt), which takes a radically different approach to RuboCop. Rubyfmt won’t offer any configuration options that allow users to effect its style opinions.

    12: A new cat named Merb!

    Sean and Sam talk about debugging a memory leak with Crates.io when upgrading to Rust 1.32 that could only be reproduced in production. The problem was related to the jemalloc memory allocator being used in the newer version of Rust. Such an issue causes an impact, regardless of the language being used. Many memory allocators exist, but you’re usually not forced to utilize a specific one or library. Sean was able to find allocations from three places: Libgit 2, OpenSSL, and MIME-types. Is there a single culprit? Or, just a ton of tiny paper cuts? The last resort would be to run Valgrind in production. In addition, Sam expresses his frustration when giving an update on progress with fixtures and script repositories for Ruby autoformatter (Rubyfmt).

  4. The Parse.y Hole

    The Parse.y Hole

    Derek Prior, engineering manager at GitHub, joins Sam to talk about what they’ve been working on these days. Derek’s doing GitHub projects that can’t talk about. But, he did mention that GitHub recently shipped small-scope changes to its issue templates. Sam dives deep into details about building a Ruby auto formatter and not wanting to be the sole dictator of style for the rest of Ruby for all time. Feedback from others through a request for comments (RFC) process is valuable for adoption and implementation. For the goodness of the community, get them to tell you all their style opinions! Then, everyone can look forward to using Sam’s auto formatter.

    10: Deleting all of a user's comments is probably a bug

    Ruby's language development is off the charts. Also: we talk about programming. Sam and Sean discuss Ruby, auto-formatting, and whether Hash Rockets are good. They bring other languages, such as Go, Rust, and Elixir, into their formatting discussion. Also, Sam shares some work-related news. He’s leaving his job at DigitalOcean. Before he goes, he wants to get as much done as possible to give his team the best opportunity to succeed. That’s the mark of a truly great manager. But, at the same time, he’s looking forward to his next gig! Sam Phippen on Twitter Sean Griffin on Twitter RubyConf Hash Rockets are good actually Justin Searls Ryan Davis

    9: Tools That are Well Built Will do it for us!

    We’re still time travelling, Sam has since left DigitalOcean, but in this episode, he talks about his experiences there. Sean talks about his experiences managing the crates.io team, and incidents on an open source project with volunteer time. Sam talks about his experiences scaling go programs, and processes vs threads, as well as why kubernetes makes the trade offs between goroutines and processes pretty unimportant.

    8: Vulnerability

    Yak Shave - Episode 8 This episode was recorded on October 21st 2018. We thought it best to get this to you, even though it's a little stale :) Remember that dark, scary time in October 2018 when GitHub went down? Sean is joined by Derek once again to discuss what they've been up to. Sean not only experienced frustration with GitHub’s downtime, but Crates.io's dependency on it. There’s been a lot of heated discussions in the community about Crates.io’s policies, or lack thereof. Specifically, focus has been put on crate name squatting - the practice of uploading an empty crate to reserve the name. Sean wants to prevent or eliminate such disruptive and malicious behaviors and actions that force action to be taken and policies to be revised or created. Do not disrupt service to make a point. It wastes everybody’s time! Sean had a stressful week and knows he will not always agree with users. But, in the future, he promises to remain engaged and responsive. Fortunately, Derek had a good week - thanks to the Suggested Changes feature he released for GitHub.

  8. It's not a Pyramid, it's a Diamond

    ٠٤‏/١٢‏/٢٠١٨

    It's not a Pyramid, it's a Diamond

    Sean and Sam talk all about testing. Sam created an ideal testing pyramid based on personal experience and from talking with test thought leaders, such as Justin Searls. The testing pyramid has “integrated” at the top, and “isolated/unit” at the bottom, along with a wide base and X axis for the number of tests you should be writing. Write as few integration tests as possible, although you may write some that you don’t keep. Isolated tests refer to where the only thing you are executing is one file or function’s worth of code. Then, there’s some tests to never write. You should be able to look at a test and know instantly if it’s correct or not. Whether using a pyramid or bowtie scheme, teams should embrace testing, rather than hate it.
