We've done lots of load testing and the CPU and memory footprint of the Go version is better than the C++ version. Not surprising since we reduced the code size so much, but at least using Go did not involve significant bloat.

OP here. I do actually use vim but I have yet to adopt most of the fancy plugins that vim provides -- put me in a time machine back to 1977 and I would be very capable of programming on any UNIX system that you'd drop me in front of, p

OP here. It is absolutely true that we did not rewrite the entire original system in Go; I tried to be very explicit about that in the blog post. But, I feel confident that it could be done, in much less code, with greater clarity and modul

OP here. What do you think we should be using apart from C++ or Java?

The joke goes, "If every other line of code you write starts with 'if err != nil', you might be a Go programmer."

The problem is that no promotion = no job. So if you care about teaching, you need to get tenure.

People denied tenure in CS at Harvard have gotten senior (tenured) jobs elsewhere, but not in my opinion at places anywhere near as good.

You are right that being a mathematician at Harvard, it hardly matters if you get tenure or not. (In fact, for a long time you basically had to win the Fields Medal to get tenure in math at Harvard). Harvard is nowhere near as well known in

This isn't true in computer science at Harvard - I speak from experience, having gone through the tenure process there myself. Being denied tenure in CS at Harvard is about as bad as being denied tenure anywhere else; people don't

The author of this article is a friend and former colleague (I had the office next door to hers at Harvard, when I was on the faculty there). Many of the reasons she cites for being "miserable" as a faculty member reflect why I le

As a former professor at Harvard, this is a welcome move. However, I don't think it goes far enough, and it should have happened much sooner. One thing I will say: The fact that the administration felt the need to snoop on employee e-mail t

The sensor networks research was work I did at Harvard prior to joining Google. I don't think Google is very interested in my deploying sensor networks on volcanoes, although (to be fair) I have not asked.

Thanks for the comments; I replied on the blog post itself. TL;DR: Even tenured profs care about helping their students get good jobs, which means publishing in top venues.

by mdwelsh 13y ago
That's unfortunate. I'd be curious to know where you ended up taking a job. I have been surprised at how "academically inclined" Google is; however, I am sure there are groups here that have less interest in research-type endeavors than my

I work for Google, and I think it's an awesome place to work, but I can see in my two years there how things have been changing in subtle ways. It's not a small company anymore, which hasn't changed how "cool" it is, but does mean that with

An Interplanetary Internet is not a joke: It's been a serious field of study for a while. There is a SIG on the topic, and lots of work has been done to think about how Internet protocols would work across interplanetary distances and frequ

Pretty amazing memoir. Does a nice job of capturing the ups and downs of the grad student experience. Phil - consider distilling this down as a blog post or two - lots of good lessons here, but given the length they might be lost on most or

Also keep in mind it's using the Chrome networking stack, just not the rendering and JS engine.

Note that Chrome on iOS does use the Chrome networking stack, which has a lot of enhancements - including SPDY.

Mark - thanks for posting these. I was the recipient of my own batch of such rejection letters during my faculty search in 2002, so I know the feeling exactly. I ended up going to Harvard (not bad!) but the sting of rejection still hurts, n

This looks awesome. Does anyone know if SPDY support is in this release?

by mdwelsh 14y ago
SPDY does not technically require TLS, but It's the Right Thing To Do [tm]. According to Mike Belshe, there are two reasons that SPDY was designed to use TLS. The first was pragmatic: Middleboxes on the Internet wouldn't be able to pass thr

Sorry for not being clear. I completely agree that Opera's experience is relevant and useful. They have done some great work on optimizing mobile web performance and it would be fantastic to draw on that expertise to make open standards whi

There's a big difference between having a closed, proprietary protocol and releasing something as open source with a public spec.

We wanted to use a real phone to accurately capture the performance of the phone hardware, browser (Chrome), and OS (Android). For example, JavaScript runs much more slowly on most mobile platforms than it does on desktop browsers, and we w

Hi Juho, I'm the guy who did this study at Google. I agree with your criticisms that the measurement setup does not reflect real network conditions in all cases. However, we have done a tremendous amount of measurement on real mobile networ
