I'm an engineer at Cloudflare, and I work on Unimog (the system in question). You are right that even balancing of utilization across servers with different hardware is not necessa…

Wow, unusual topic for the front page of HN. I visited about 5 years ago. It was my wife's idea to go (it's quite far from other attractions, so you have to plan a visit), but we b…

Thank you! We often use on Creative Commons-licensed images in our blog posts. We always include credit, but we owe a big debt of gratitude to the people who take these photos and …

I spoke too soon! We're going to disable this change for a while. Sorry.

I work for Cloudflare. Thanks for bringing this bug to our attention. We have just rolled out a fix. You might need to go into the CF dashboard and purge the cache for your site to…

I saw lots of these in Morocco, between the mountains and the Sahara. Well, what I saw were the regularly spaced mounds of earth at the top of the access shafts.

"As of yet I don't have a clear picture what this new driver will look like once evolved besides hearing 'boxes, many fucking boxes mate', when being told about the increased abstr…

So "native" means "not VirtualBox" now? Docker for Mac might be a significant step forward compared to the previous solutions, but it still involves a Linux VM. I guess you could s…

A few things about the article that made me think "hmmmm": No mention of testing set-up. Was the test client running on a different machine from the server? What kind of machines? …

The linked article states 100 Gb/s, i.e. gigabits per second. But the post title says "100GB/s" which suggests gigabytes per second. Worth correcting, because getting 100GB/s betwe…

Yeah. This bit me on the first ascii diagram of mine I tried it on. But other than that, very neat.

Indeed. Kernel-bypass networking is great when you are building something that just receives and send packets (and maybe does other things that can be moved to other threads within…

We did try TUN/TAP. It seemed to be slower than pcap. Our answer to weave performance concerns is on its way: http://blog.weave.works/2015/06/12/weave-fast-datapath/ We're really i…

I agree with other posters who say that everyone makes syntax errors, and that relying on documentation is fine (consulting documentation, and not just banging out something that s…

Are you in London? If not, move to London - it's where most of the start-up jobs and interesting tech jobs in the UK are located. Also in London, there are also lots of tech meetup…

Has any Greenplum DBMS code actually been released yet? Please correct me if I am wrong, but as far as I can tell, there is only a commitment to release it at some indeterminate po…

You make it sound like achieving what weave does would be straightforward with the existing in-kernel encapsulation mechanisms. That's not the case. Even if putting some parts in t…

amqp.node has a callback-based API if you don't want to use the promise-based API. But this guy reimplemented it, apparently because he doesn't like promises ("This library solves …

The PHP world is so adorable. It's like a bunch of little puppies, running into each other and falling over and tumbling around.

I'm 38. If you run Linux on an x86 desktop, you use code that I wrote in 1997: The MTRR support in http://cgit.freedesktop.org/xorg/xserver/tree/hw/xfree86/os-... (big chunks of th…

His name is misspelled in the thread title. It's "Khamenei" (and pronounced a bit liked "harmony").

The linked article is about a decline in the rate of CO2 emissions, not a decline in atmospheric CO2 as the HN title suggests.

I'm sure this is good for many things, but it won't make a great digital oscilloscope. A sample rate of 125Msps is not really high enough for a bandwidth of 50MHz in that context. …
