Well, the post I responded to included a more or less textbook description of template based rendering. It's a response to a response to this: > The bizarre practice of assigning session keys to visitors and somehow storing the page

by jsolson 9y ago
I, at least, did not downvote the original post. I assumed it was honest ignorance of the practice I described in my reply.

What's being described above isn't simply template-based rendering (which, yes, essentially everything does), but the practice of building web-software like desktop software and keeping the state of the UI server-side. It ignore

It's... an extremely common accounting term? First day of Accounting 1 or so? It's common enough that it's been used as the title for a pop animated sitcom episode -- Archer (S2E2).

Agreed. As a policy, we don't sign off on supporting things until we feel we have sufficient regression testing for them in our automated qual matrix. DPDK is not there yet.

It's not that their SR-IOV implementations are incompatible, it's more that SR-IOV doesn't imply anything about driver compatibility. It's is a mechanism for exposing underlying hardware (or slices of hardware) to guests
307.
by jsolson 10y ago
In open source vhost is a pretty good option that abstracts hardware away from VMs and generally performs well. That said, SR-IOV isn't a BAD option if you don't care about live migration of VMs over a lifespan potentially longer

by jsolson 10y ago
Unfortunately it's a bit more complicated than that, which is why I hate that SR-IOV gets so tied up in this :/ When they say "virtio-net" there they mean virtio-net inside qemu with vhost servicing the queues on the hos

We do not, although in practice as a guest you wouldn't necessarily know one way or another. Speaking from (decently informed) personal opinion here-- I see SR-IOV as a means to achieving certain networking characteristics, but one tha

Note that DPDK works just fine with virtio-net on GCE as well, although we have not declared official support for it. In terms of RDMA and bypass messaging, I agree there can be substantial advantages to offloading transport layer message p

With respect to #2 -- "more quickly" could be a bit much, but there are quite a few combination locks (of the sort commonly found on cheap-ass high-school lockers) wherein getting within 2-3 digits of each digit in the combination

by jsolson 10y ago
My natural reaction to that would've been to leave the school and every locker in it unlocked over the course of a weekend. Not claiming any responsibility for it, naturally, simply observing that it had happened.

We (Google) do both. Having recently done some coding in Swift to implement a little toy Hypervisor, I sorely missed these annotations. By and large the errors they catch are ones I'd be embarrassed to have pointed out in a code review

You are incorrect. If you have many threads each doing small amounts of work before blocking, the kernel will happily switch in another runnable thread when the current thread blocks. This is common in workloads that service network IO usin

Thinking of it that way for single-node configurations (or static collections of multiple nodes) makes sense, yes. A lot of the promise of GCE and GCP generally come from on-demand scalability, autoscaling, serverless, etc. Those become muc

You can (or could, anyway) force it to open in a window (right click the app icon and select "open in window"). This allows you to go really fullscreen and fixes control keys (C-w works again rather than closing the tab).

Re-reading it and checking out the demo on https://shattered.io/ it looks like it's even stranger -- some PDFs are "safe", so it may be that it requires the original document (and hash) to have certain proper

No. I don't know the details of the attack, but a third possibility (as I read it) is that both PDF documents are modified in the process until they arrive at a collision. PDF has the convenient property that you can inject arbitrary

This sort of invites the question of what you WOULD be interested in working on (and what size team you've been leading) if you were to consider leaving. Asking as a Googler who occasionally gets to dream up a neat trick here or there

This is fair, and what I've done so far in Swift (with a cute little extension on NSLocking no less :). If you're going to add moveonly types with destructors, though, it seems strongly desirable to give them (or at least making a

Indeed, my point was that if you're going to add moveonly types with destructors having a way to force lexically scoped lifetime has concrete uses. That said, having that be optional opt-in behavior could be valuable from a compiler op

I appreciate the GCD approach, and for many problems it'd absolutely be what I'd suggest and use myself. My little Dwizzle toy could certainly be built that way. For concrete systems programming tasks that deal with things on a pe

First, let me point you to where such tolerance has been effective at advancing agendas (note that in neither case do I agree with or support the agendas). My preferred concrete example, simply because of how staggeringly effective tolerati
