Piper is awesome, but it's not unreasonable to think of it as Perforce if you designed and built Perforce to scale to handling all of Google in one repo. It has basically the same set of nouns and verbs. citc is the really magical bit,

So, I've made it from Burlington, Washington to the Canadian border without turning off Autopilot in Friday evening traffic (about 50 miles, including some pleasant winding interstate). As described by Subaru LKA "...can gently gu

ioeventfd for PIO exits is still handled in the kernel, but that one is easy since it's a dedicated VMEXIT type. We do very little that typically requires trapping MMIO, particularly in places that are performance sensitive (VIRTIO Net

We do not. That it's not vhost you can infer (correctly) from the topology of our VIRTIO Net device; specifics on that front will have to wait for another day, though :)

Adding to Andy's point here -- if you consider the services that back GCE in terms of the features offered by our virtual networks, virtual storage devices, etc. they necessarily have tight dependencies on "How Google is Built&quo

Yeah, it still gets hit now and then. It should not get hit often in the typical steady state, though, which is why you can punt it to userspace with little performance penalty. (I work on the custom VMM we run)

When I took it we were encouraged to use Weka for the algorithm implementations themselves. This certainly allowed me (and I'd never so much as touched machine learning prior to taking the class -- I took it on a bit of a lark that was

Fair enough, and I should have been a bit clearer in my original post. In my experience with the MSCS program (nearly ten years ago at this point) the core required classes were mostly well structured and would serve people well continuing

I did both my BSCS and MSCS at Georgia Tech. While I have many complaints about the school, the quality of the classes is not one of them, for either the undergrad or grad programs. That said, with a couple of notable exceptions, the gradua

In my experience it most often manifests in the form of columns that are constrained not NOT NULL into which you suddenly can't insert, say, a user who has no last name.

I don't agree on the free trial. I think it lets you play around a lot more than the AWS free tier -- as I said in my comment up the thread, go ahead and move the slider to the right and scale up a bit (a little -- the free trial is st

Depending on how you use the services the AWS free tier is actually worth less than GCP's $300 free-trial credit: https://cloud.google.com/free-trial/ I will give Amazon that theirs extends out to a year, but summ

I should really find a better way to phrase that comment. I wasn't actually there for that long (a bit over two years), but I still regret not leaving sooner. I was hired in as an SDE2, which at the time was probably the right level du

So, the great irony of the leadership principles was the lip service they were paid at Amazon and how much I miss them since leaving. They're a seriously good bit of Amazon culture that's been perverted into something you can use

Not really. Principal, maybe, but SDE3 is a position you can be easily hired into with enough experience. As a promo it's a bitch, though, and absolutely not worth it. Jump ships for something level equivalent at a company with better
