How do you build up the incremental changes? By staging them into your working directory from the one giant commit?

It literally bought me a boat this week. I picked up some at the money May calls Monday. I sold them today, and (mostly coincidentally) bought a sailboat. The options, after taxes, covered the boat and this year's moorage. Could'v

Yes, but given today's technology (and my lack of faith in a suitable deity), I do not have confidence in continuity after corporeal death.

Interesting. I would like to attribute my desire to live "forever", at least to some extent, to cosmic perspective. One day the universe might make me bored, but today is not that day, and I suspect tomorrow isn't either. I d

If by mixed do you just mean residential over retail? Is the Bay Area actually opposed to that?

Having interacted with a lot of computers over the years (including Google's for the last several of my employment), the machines at Google come as close to thinking as I've ever encountered. Two or three times a day they come up

Wait, what about the whole sum... ohhhhh, right, clouds. Clouds. Always clouds. No summer ever. Clouds always.

You can trade BTC/LTC and BTC/ETH as well, though, and all of the cryptocurrencies can move into/out of them at will. There are steps they could take to ensure liquidity in USD, but they're relatively expensive. I, perso

I transferred in excess of $50k USD out without incident. Could I have done the same with $1M USD? I have no idea. The bar is considerably higher than $1k, though, and I'd wager is considerably higher than most people have to comfortab

by jsolson 9y ago
The bit about not being able to cash out over $1k is flat out false. The order book history from GDAX (I maintain a personal level 3 copy) also doesn't suggest market pressure at $12k beyond a lot of opportunists (myself included).

I mean, I suppose I'd be happier with Racket? Bonus points for building a #lang for expressing trees and operations on them. (note: this probably wouldn't actually get you bonus points, and might result in my wildly gesticulating

This isn't that terrifying guardrail-free road, though -- I drive this in a Model S ~15-20 times in each direction every winter on my way between Seattle and Whistler. Autopilot is fantastic for that trip between UW and turning onto

No. Unsubmitted changes at Google usually come in one of two flavors, short-lived (abandoned or submitted within a few days) or perpetual. The latter flavor is often for "I think we might want this". It's not uncommon for tho

Mercurial (with lots of extensions) sits on top of Piper at Google. It doesn't replace it.

While technically true due to some features of tooling, that is really only masking off part of the repo under a READ-ONLY directory. Builds can (and usually do) depend on things that aren't part of your local checkout. I'd say Ci

c5 wasn't available to me when I made that comment, or at least c5 numbers weren't — we have them now, although we're observing ~10 µs worse than your one-off in ours. It's certainly a nice improvement over what we see o

The ability to have something like CitC (or this post's git virtual filesystem) is certainly one big advantage -- no need to clone new packages, they're right there in your "local" source tree. Bazel (blaze) is another,

I cannot agree with this enough. I'm a pretty capable "generalist software engineer", but what keeps me employed is expertise in virtualization and high-performance virtual networking. Prior to that, it was expertise in distr

That was my initial reaction, but it leads to a question: do you stop doing R&D (and shed talent as a result) because production in another part of the company is blocked by some (hopefully transient) supply chain issue?

Indeed! I didn't leave too much to the imagination with my replies on the original post[0], though. Honestly, I'm mostly curious about how much of "KVM" you're running that's stock, how much is modified, and

Yes, sorry, I fully expect that's what they're doing -- I was really writing two replies there -- 1) You don't have to pass PCIe through to hardware to get performance that makes it look like you have. 2) We know they'

I do, hence my speculation about putting the NVMe in firmware instead of hardware :) (Colin's speculation in a peer reply is also reasonable -- personally I've seen enough errata in "off the shelf" IP to shudder at the i

It's fun to speculate about how other clouds do things :) > There's absolutely no way that they would get the performance I'm seeing from an emulated disk. We're talking to real hardware, exposed via PCI passthrough.

edit: It's late here and I think I misread this originally :) The differential between public IPs and internal IPs is tied into the path packets take after leaving the host. The path out of the guest is identical for both, but using VM

It's similar, although distinct. By building on a common foundation of Google networking dataplane bits, Jake's team (and peer teams) get easier integration with Google's other networking infrastructure for features like DoS

Replied to a sibling, but I believe our latency is currently coming in under theirs. Their largest/newest VMs advertise higher peak bandwidth than we do. The latency difference would certainly be most directly visible in microbenchmark
