Someone like Amit doesn't need money; by the time you get as highly placed at Google as he was you will be wealthy. I believe that Uber has interesting engineering challenges but likewise have doubts about their profitability.

SRE here. If you can handle your work nobody cares how much you are in the office. At all. However, unless you are insanely organized you won't be able to do this every single week--most successful googlers have several projects going

You cannot hire top-quality engineers who are willing to do shift work.

Yes, this is certainly a state you would desire to avoid. However, you didn't answer any of my questions.

Can you go into more detail regarding the prohibitive consistency issues? How do you maintain consistency in steady-state (ie. not during migrations?) Also, how do you make the call as to whether to bring your site down vs. attempting a liv

It would be interesting if someone from Github could discuss why they chose to do this migration by taking the whole site offline and doing the migration all at once. Did anyone investigate if this could be done without taking the site offl

What's it like to administer a cluster of Mac Minis? Do any of the popular open-source orchestration tools work?

Consider that if you collect device fingerprints, you can detect users who live together, because they are likely to share devices. If somebody bad then gets access to that data, they could do creepy things to your users.

This is generally known as "device fingerprinting"--there are many ways to do it but they all involve probing for unique properties of a client via JS / Flash (listing installed fonts, drawing invisible characters and measuri

I think what will actually happen to requests in flight is: - partial data received by old HAProxy is lost as old HAProxy exits - new HAProxy comes online, binds to port, receives fd - iptables rule removed. new HAProxy starts receiving new

by coops 12y ago
I feel I must point out that this relies on your clients to retry packets that iptables drops, so at the least they'll have a slower experience than they otherwise would. I believe that this will also break requests that are in flight

Er, yes, hi Evan! Cooper here. I believe either you or Andy originally pointed this interesting HAProxy restart behavior out to me, in the context of explaining why you wrote Einhorn.
16.
by coops 12y ago
This is generally correct. In particular, when the HAProxy process is stopped/restarted there is a brief period during which the port is not bound by either process. (If the new process isn't able to get the socket when it boots i

by coops 12y ago
This release contains a neat feature: you can now bind HAProxy to a specific FD opened by its parent process. This means that you can babysit your HAProxy processes underneath a parent process that opens ports and get hitless HAProxy resta

"A simple Hubot command can reroute our traffic to their network which can handle terabits per second." Really? You have to round-trip through Campfire to control your network?

This is a terrible question so I'm not going to answer it, but if you are interested in reading about the corrupt history of Myrtle Beach (and the greater Grand Strand area) I strongly recommend Will Murdock's Banana Republic: A Y

Funny to see this post pop up in a thread about how dysfunctional SF city government is. Myrtle Beach is effectively governed by an oligarchy of property development families.

sorry, no, you're all wrong. those employees are all taking unpaid leave to come work on healthcare.gov.

You must not have tried very hard. http://techcrunch.com/2013/10/31/oracle-red-hat-and-google-e... People are still flying out there to help with healthcare.gov, all the time.

by coops 13y ago
For all their hand-wringing over the healthcare.gov debacle you'd think at least one of these DoBT guys would have gone in to help fix it. That probably would have gotten in the way of fund-raising, though.

I have done this the last 2 times I changed jobs. It worked out well for me both times. If you are considered to be a valuable employee, and you have management that is the least bit competent, you won't "just be replaced" fo

most google search outages at this point are the result of some kind of bad configuration push.

if i recall correctly, likes were pretty dark-testable, since we didn't make them visible until we released them. so we were able to use a methodology similar to the infinite-scroll dark test--X% of items viewed by client in the app trigger

similarly, engineers who won't criticize or endure criticism of their own work are seriously poisonous for a company.
