In this case they reported Stripe's annual run rate — a metric that's roughly comparable to annual recurring revenue, but for non-recurring business models.

I'm also seeing a lot of 1016/1018 "Origin DNS errors" across a variety of web services. I saw this on my own company's website first around 21:40 UTC, although it's not bad enough to materially affect our traffic volume.

This is a different article, going into more of the technical details of the desktop update. The other post is for a more general audience.

Quick notes on the BBP2's after about a week:

* The sound quality is excellent. Wired or wireless, the sound is sharp and crystal clear. But it's not particularly flat; there's a lot of midrange that makes it sound a little muddy. I've set up a custom configuration for the iTunes equalizer that helps with the (rock) music I listen to: punchy bass, clear treble, but less mud in the middle.

* The noise cancelling isn't bad. It does a great job on public transit but it's not as all-encompassing indoors as the Bose QC35 seemed to be, from the little I've tried them.

* The BB2Ps aren't nearly as ugly as the product photos make them look. They're not particularly brown in real life, just dark.

* They're pretty comfortable although I find it fatiguing to wear them for more than a couple of hours. The new over-ear shape looks like it made a big difference on the comfort level.

* The Bluetooth signal tends to cut out quite a bit from my iMac at home, which is pretty disappointing. It works better from my MacBook Pro at work -- not sure if there's some interference at home or what.

Overall I do like them, but I don't know if I like them enough to justify the $200 I spent. I haven't decided yet whether to keep them long-term. If I don't keep these, I might switch to the Beats Solo3 without ANC, or just bite the bullet and go for the Bose QC35...

This was extremely helpful -- thanks so much for that detailed comparison. I just ordered the Backbeat Pro 2's from Amazon. Although it would be nice to have the Bose ANC, that's less important to me than sound quality -- and $349 just feels like too much to spend on headphones. I'll let you know how the 2nd gen looks and feels.

How would you compare the Bose QC35 to the Plantronics? I know Marco Arment has fantastic things to say about the Backbeat Pro series, but I've never seen or heard those in real life, or even seen them mentioned in most reviews. I've tried the Bose a couple of times: the ANC is excellent, and I like the sound (but I'm not blown away by it).

My muscle memory for "terraform apply" was too strong, so I just moved "terraform" out of my path altogether. Now I have a wrapper that invokes it safely (or a Makefile, depending on which project I'm working on).

It's actually cheaper than data transfer across AZs. Within a region, AWS charges 1 cent per GB in each direction. You pay a cent to send data from one instance and another cent to receive data on another instance. But between Virginia and Ohio, they charge 1 cent to send data (in either direction) but receiving data is free. In the end, it's actually cheaper to balance your servers across one AZ in Virginia and one AZ in Ohio, rather than 2 AZs in the same region.

But it's only a penny, right? How much could it matter? It actually matters a lot. At both my previous and current employers, a surprisingly large portion of our hill comes from data transfer across AZs. All the microservices, all the memcache hits, and all the database replication add up quickly.

Yep, the email still goes out every week.

My understanding is that the founding of the Chan Zuckerberg Initiative has no tax implications at all. The only way that tax would be avoided is if the foundation sells some Facebook stock and donates the proceeds to accredited non-profits in the same year. But the exact same deductions would apply if the Chan-Zuckerberg family donated directly.

We've used it occasionally on a ~400GB table and it's worked perfectly for us too. We run it on EC2 i2.8xlarge instances and it finishes in under 2 hours. But it doesn't use very much CPU or I/O, so we could probably run it just as well on a smaller instance like an i2.2xlarge.

One downside is that you need enough free space on your disk to hold the packed copy of the table, so you need to run it before your disk gets too full. The last couple of times we've waited too long, so we've had to move the data to a larger host before we could repack it.
