Oh, huh, yeah, that makes sense. That would totally work. Cool idea.

Tobi knows DHH; apparently we started building with rails before its public release. Don't quote me on that, but I've heard it in passing a few times.

Yep. But even then though, what if: class A B = "c".freeze end And elsewhere: class String def freeze raise "because I can, that's why" end # or even method_added,

We've talked about trying to implement this strategy (load everything, dump/restore the heap) with MRI, but our thought experiment was on the scale of a fully-booted application. In that context, it gets difficult to determine how

No. I'm not opposed to it, but we don't use it at Shopify and I doubt the RubyVM::InstructionSequence API is compatible. Bootscale should work, and the load-path-caching feature of bootsnap should work too, if you can get the gem

Sadly, the 2.3 requirement is inherent, since the RubyVM::InstructionSequence dump/load API was introduced in 2.3.0. However, you could probably still benefit from http://github.com/byroot/bootscale .

Heh. I write an internal developer tool at Shopify that is (somewhat) conceptually similar to vagrant. ( https://twitter.com/burkelibbey/status/858013844626649092 ) Like you, we distribute it as a git repo. We don&#

The largest culprit for slow ruby boot times is an O(n) number of syscalls over the LOAD_PATH each time `require` is called, so the number of syscalls is essentially O(n*2) to the number of gems. The load-path-caching feature of bootsnap (c

FWIW, the machine that generated all of those times: * MacOS Sierra * 2.6 GHz Intel Core i7 * 16GB 2133 MHz LPDDR3 * 500GB SSD, whatever Apple ships.

I've tossed around the idea of writing zeus again now that I actually understand the language I wrote it in. Spring is much simpler, but because of the manner in which it's loaded, it isn't capable of detecting certain types

Nope, we've been Rails since before Rails was even public. I'm sure we've hired a PHP developer here and there over the years, but our core platform has always been Ruby.

Honestly, it works well for us. DHH may have been a little rosier than necessary: there are some downsides, to be sure, but we can mitigate them to a large extent (e.g.: TFA), and we get a lot of benefit out of the architecture. It is defin

The particularly frustrating thing, when I've started thinking about optimizing boot time at a VM level, is that it's near-impossible to "understand" what loading a file actually does, since it's all just evaluated

> How does the fit in with zeus and/or spring? Two orthogonal optimizations: It definitely plays nice with spring, speeding up the pre-fork rather a lot, and the post-fork a little bit. I can't think of any reason it wouldn&#x2

I'm sad that Beats was the one headphone brand that Apple ended up purchasing when they wanted to expand that space. B&O felt like a natural synergy for them too. I would love to be able to buy better-sounding AirPods under an Ap

The thrust of Sagan's monologue was to encourage re-evaluation of religiously-motivated anthropocentrism. To me, at least, it's less of "how could anything here matter when Saturn is so big?" and more of "does it re

* A CO2 level of 7kppm is not compatible with human flourishing. * Consensus is that the elevated CO2 levels of the Ordovician-Silurian and Jurassic-Cretaceous periods came on over tens or hundreds of thousands of years, not mere tens or hu

While this is certainly true, it's unfortunate that we can't even have a productive conversation about this issue because we're apparently still stuck on disagreement over scientific consensus.

While I understand the argument for simplicity and agree with the premise in most cases, I find it pretty hard to argue for this code: ys := []byte{} for _, x in xs { ys = append(ys, f(x)) } over something like th

A charitable interpretation would be to project the right/wrong axis onto compatibility with our continued flourishing. If you accept human flourishing as "right", the arctic climate is quite wrong. It's a bit of a reach

Based on his twitter it looks like it was just an interesting thing to learn over the holidays or as a 2017 thing.

Indeed, and it's curious that a lot of the more would-be-impactful things have come later in his term when he faces stronger opposition. I don't have any explanation for this.

Yeah, well the problem is that while Trump campaigned on change, the actual changes he plans to implement will just centralize wealth at the top even more . America had a chance with Bernie, but due to some combination of media attention,
