Not unless you like pain. CockroachDB is distributed and uses Raft consensus under the hood, so you can't take a snapshot of just one node; you need to take a snapshot of all the nodes in your cluster, and you need to take those snap

JavaScript is an interesting case, in that it was the only way to write code that would run in Netscape Navigator at the time. In a sense it had Netscape behind it, and then it had Microsoft behind it once they reverse-engineered an imple

Yep, definitely. In this specific case of a missing unsafe marker you don’t need symbol versioning at all; you need the stdlib to somehow present two signatures for the same function that the compiler can select between according to the Rus

With all due respect, I do think you're conflating the way things are with the way things have to be. glibc has a similar commitment to never breaking user code, and yet symbols have been removed from glibc! The trick is to use &quot

Well hello, Dan! Nikhil here. It’s always nice to get a reminder that the internet can be a small place. (Dan and I were at RC concurrently for the second half of his batch.) I’ll echo the sentiment: RC is a really cool and unique place. I

I'm not sure what you're arguing here. Yes, I described a very specific type of optimistic concurrency control that can be layered on top of Calvin to provide support for dependent transactions. (The "optimistic" is in t

You can always execute dependent transactions in a system that does not support them by running two non-dependent transactions. This is covered in section 3.2.1 of the Calvin paper [0] as the Optimistic Lock Location Prediction (OLLP) schem

I've had entirely the opposite experience. Have you ever tried to install a package in Sublime? You have to use a separate tool, Package Control, whose installation instructions are arcane: import urllib.request,os,hashlib; h = &#x

I can't speak to this with absolute certainty, but I have some speculation to offer. The story of GOPATH is tightly intertwined with the story of package management. Go is a Google project, and Google has a very unique approach to pack

Before you get too excited about possible performance wins, note that gccgo turns out to be much slower than gc (the standard Go compiler) on a lot of real workloads. Here's one such benchmark, taken recently, though it's admitted

My biggest frustration with the auto-update is how long it takes. I wouldn’t mind the auto-update in the slightest if it took 5s instead of 30s. It’s ironic (and a testament to your work on bottling) that the longest phase of installing a f

Simply drop the assembly as a .s file in a Go package and run `go build`. See Go's hash/crc32 package for a real example [0]. There's a lower level `go tool` command, of course, but I don't know it off the top of my head

I would love for this to be true, but I'm afraid I don't have any evidence that it is. What are the better options you'd recommend? More specifically, Google's Bazel [0] is the most serious attempt I know of to replace C

[Cockroach Labs engineer here.] Yes, if very low-latency (i.e., P99 latency sub-5ms) reads and writes are critical to your application, CockroachDB should not be your first choice. That said, one of the primary motivations for CockroachDB

This appears to be an (illegitimate?) republishing of a course that Dan Armendariz has taught at the Harvard Extension School since 2008. (The course number has since changed from CS E-7 to Digital Media E-10.) You can find the fall 2015 ma
