**Raphaël Simon:** Great, sounds good. |
**Erik St. Martin:** Who wants to kick this thing off? |
**Carlisia Thompson:** \[39:57\] I'll start. I would like to mention the CLI tool that I found. The author's name is not very clear, but I'm going to say that his Repo is mkideal, and the project's called [CLI](https://github.com/mkideal/cli). I love it because the examples are super clear and there are tons of example... |
**Raphaël Simon:** How would you compare it with [Cobra](https://blog.gopheracademy.com/advent-2014/introducing-cobra/)? I've been using Cobra for Goa, but I'm curious? |
**Carlisia Thompson:** I thought it was easier to understand and follow. If I am going to use Cobra today - because I've used it before; the first time I used Cobra in Viper - I will have an easy time. But if it was my first time, this would have been so easy because the documentation is amazing. Kudos to the project m... |
**Erik St. Martin:** I just quickly looked at this, but it seems like it has kind of integrations for other things. You can define a particular argument as a pit file and it kind of decodes that and gives you a pointer to the file so you can interact with it that way. So it kind of is an interesting approach with these... |
**Carlisia Thompson:** Exactly. And you can define your flags as slice or map, and there are the features there. |
**Erik St. Martin:** That's interesting. |
**Brian Ketelsen:** So my addition for this week is the post by Scott Mansfield from Netflix about application data caching, and it is way too in depth and too long to discuss here, but there are some really interesting discussions about data storage and data structure, Go tools like the [Rend project](https://github.c... |
**Erik St. Martin:** Yeah, I'd love me some RocksDB. Yeah, so I read that post here. It's actually really interesting... Rend is kind of wire-compatible with memcached. And basically what they implemented was this proxy almost in between their clients and memcached, and they implemented like an L1 and L2 cache so that ... |
All of this was to reduce their financial costs monthly for their Amazon instances for high memory, because they were storing lots of user data in memory, so they'd have kind of like the hot data set in a given region, but they'd also have a cold data set, in case people failed over from another region and things like ... |
**Brian Ketelsen:** Yeah. I definitely just want to shout out to Scott and the team at Netflix for such a nice and thorough write-up. I know Scott's been dragging the people who will listen kicking and screaming into the Go world; even though they're a Java-heavy shop, they do have a lot to Go behind the scenes there, ... |
**Erik St. Martin:** \[44:04\] Yeah. And I remember seeing some of the performance metrics. It was something in the neighborhood of like two million requests per second, but I think that wasn't fully active because that wasn't wired up the backend. I know when it was all set and done, the whole system was something in ... |
We'll link to that in the show notes too, because that is an interesting read and especially if you're not familiar with RocksDB and some of those things, that's kind of fun by getting to learn how Log-Structured Merge-trees work. Cassandra uses the kind of same approach there. |
**Brian Ketelsen:** Yeah. So another project that I've been following for a long time, but really only recently has started to mature is [SHIELD](https://github.com/shieldproject/shield) from Stark & Wayne on GitHub. You guys may remember Dr. Nic from the Ruby world. He seems to have endorsed Go or embraced Go, and thi... |
And when SHIELD first came out, I read the code because there was no description in GitHub and just tried to guess what it was going to do eventually and I couldn't figure it out for quite a few months, and now it's matured quite a bit, and it looks to be a really nice tool for backing up all the things. |
**Erik St. Martin:** Yeah. I briefly looked at that. I need to find a use case for it. But I like the idea that you can kind of wire up where it's pulling the data from and where it's pushing the data to. I need more time. |
**Brian Ketelsen:** Yeah, almost like the concept of [Heka](https://github.com/mozilla-services/heka) we were talking about last week. You know, this is a Heka for backups. |
**Erik St. Martin:** Yeah, that's actually a good comparison. |
**Brian Ketelsen:** Thanks for saying so. \[laughter\] |
**Erik St. Martin:** I have to make you feel better. |
**Brian Ketelsen:** After the code reviews I've been through this week, I'll take anything I can get. \[laughter\] |
**Erik St. Martin:** So another interesting project that I've seen was [zap from Uber](https://github.com/uber-go/zap), which was a structured logging framework that is supposed to have, I think, zero allocations. That was kind of interesting. |
**Brian Ketelsen:** You know, we're down here in the South so we can call that Y'ALL, yet another level blogger. \[laughter\] |
**Carlisia Thompson:** I really liked the structure part of that system. I remember when I worked, again, in the Rails app and we were using Splunk to keep track of our logs, and we had to agree upon a specific way to write our code so that it will be easy to find in the Splunk; we had to just like put certain keywords... |
**Erik St. Martin:** Alright, anybody have anything else they want to talk about before we kind of go on our merry way? |
**Brian Ketelsen:** No, it's been a pretty full show. |
**Erik St. Martin:** Or not so merry for Brian, who's gonna get peak down in his code reviews tomorrow...? |
**Brian Ketelsen:** I'm going back to my code reviews for today. \[laughter\] Don't tell Blake if he's listening. |
**Erik St. Martin:** So one of the things we like to do when we close the show is just kind of briefly go around and give thanks to an open source project kind of as you spoke to earlier, Raphael; to get kind of that feedback from the community sometimes makes your day, so we want to make sure that we're regularly reac... |
**Brian Ketelsen:** \[48:02\] I'll kick it off today. One of my favorite open source tools ever is an NSQ from Bitly. I've used NSQ in dozens of projects and it has never ever disappointed me; it's blazing fast, it is 100% predictable and reliable, and it's just amazing how much you can do with NSQ in very little code.... |
**Carlisia Thompson:** What is it? |
**Brian Ketelsen:** NSQ. It's a distributed Queue that's incredibly fault-tolerant and really fast and it's written in Go, and it's written really smartly. |
**Erik St. Martin:** Yeah. Actually Matt Reiferson did a talk in GopherCon 2014 on it. I think the talk was titled ["Spray Some NSQ On It"](https://speakerdeck.com/snakes/spray-some-nsq-on-it) or something like that. |
**Brian Ketelsen:** That's right, yeah. |
**Erik St. Martin:** Yeah, that should be on GitHub, too. |
**Brian Ketelsen:** And that video is up on YouTube, yeah. |
**Erik St. Martin:** How about you Carlisia? |
**Carlisia Thompson:** I would like to mention today [iTerm2](https://www.iterm2.com), which I'm sure most people already use. If you don't, you definitely should check it out, because eventually you will. \[laughs\] It seems that everybody makes the transition from the normal terminal that comes with the Apple system ... |
There are a bunch of new features that are very interesting, very useful. I'm just going to say I recommend that you leave... It pops up a tip of the day every day, right on the terminal. It's very non-intrusive; we can just hit skip and it will go away. Basically, leave that on and you're going to discover a treasure ... |
**Erik St. Martin:** Yeah. For when I am actually on my Mac recently, I have the little tips on there because it's been a while since I've explored features at it, so I'm letting it annoy me periodically to tell me things that I should be doing. |
**Brian Ketelsen:** They've added some really radical stuff to iTerm2. The latest betas are pretty crazy in terms of the toys that they have added. I'm not sure if I'll ever use them all, but they are impressive. |
**Erik St. Martin:** I get a little jealous because most of the time I work off of my Linux workstation so, you know... GNOME terminal is I think the current one I am using in i3, but it's not the same. Raphael, do you have a project you'd like to thank? |
**Raphaël Simon:** Yeah, actually we started using RethinkDB, and it has been very interesting. I stumbled on it kind of by chance and was reading the description and the feature set and it all sounded good, like it usually does. But then what really struck me is how well it fit with the use case that we were after, wh... |
\[51:39\] And something else I wanted mention - it's not a project, but I wanted to give a shout out to other companies that let their own employees develop open source projects, because it takes time, and we all going to have to make a living, and at the end of the day the companies that allow their employees to devel... |
And I'm thankful for RightScale obviously with Goa, but I was also thinking about JP Robinson at New York Times doing Gizmo... I mean, there are many, many examples of people that work in the industry and where their company actually pays them to develop open source projects. I think that's awesome. |
**Erik St. Martin:** And I actually get to cheat because we got to just talk about the Netflix post and RocksDB, and I love RocksDB, so I'm going to give a shout out to them. \[laughter\] |
**Brian Ketelsen:** That's cheating. That shouldn't even count. We're taking this one off of your scoreboard, Erik. |
**Erik St. Martin:** \[laughs\] But, I mean, it's awesome. If anybody hasn't played with it, they should. And even just investigating kind of how Log-Structured Merge-trees work is kind of fascinating. So I think with that, we are just about out of time. |
I definitely want to thank everybody for being on the show and especially, Raphael, for coming on and talking to us about generating all the things. |
