Hey, it's HighScalability time:
Will Minority Report for developers really help us program better? (Primitive)
- October 2017: ICANN changes the DNSSEC root keys; $2.91M: cost of running Let's Encrypt; 20%: Amazon convenience tax; 100%: increase in spam; 6.2 km: Quantum teleportation across a metropolitan ﬁbre network; March 18, 1982: birth of containers; 6 months: how long a lightening bolt can power a 60 watt bulb; trillions: EV cache hits per day @ Netflix; 5x: Spark is faster than MapReduce; billions: HTTP, Git and SSH connections served per day at GitHub; 28: # of websites in North Korea;
- Quotable Quotes:
- @vgcerf: It is time to admit after 18 years that the multistakeholder model of Internet operation works. #yestoIANA
- @EricLathrop: Netflix found a 5x performance variation between AWS instances at the same price! They benchmark to avoid overpaying. @indirect #Strangeloop
- @swardley: Perfectly reasonable @NigelBarron. Larry's statements are ludicrous, play is to milk existing customers whilst hoping to find a new future.
- @BethanyMacri: Etsy is very anti-SOA. Monolith forever!
- marknadal: This is the way humans have been thinking for thousands of years. And guess what, I sat down with a large airline and had to warn them "we're not Strongly Consistent" and they laughed at me saying "you realize we've been booking seat reservations before there was internet, before you were born, and before there was cheap telephony. Seat reservation has never been strongly consistent - we used to have hundreds of travel agents booking seats and it would take 2 weeks before we would hear about it."
- Jason Feifer: All I have to do is go to another website and see the price is different, and I don't. It's crazy. Like, why am I not doing that? We're the problem.
- @cmeik: "The clock-free design paradigm I promote must eventually prevail. It fits Physics."
- @gabrielgironda: mclaren and apple are a great fit. all the stability of apple's software combined with the reliability of british automobiles
- Bryan Cantrill: The virtual machine is vestigial abstraction. We can not get to #serverless without getting rid of of the VM.
- @dchetwynd: The number of US households that only use cellular data has doubled from 10% to 20% between 2013 and 2016 #strangeloop

- Interesting results from a major architecture change at Netflix. Zuul 2 : The Netflix Journey to Asynchronous, Non-Blocking Systems. Netflix had a blocking servlet connectionless based architecture and they moved to a nonblocking asynchronous connection architecture. In general, from a latency, CPU, throughput, and capacity perspective the async version didn't perform much better than the old sync version. Netflix found "the less work a system actually does, the more efficiency we gain from async", which makes sense in terms of scheduling and IO. There was a big win however in the ability to scalably maintain over 83 million persistent connections, one for every client, back into their cloud infrastructure. The cost of a connection becomes a file descriptor instead of a thread, which is a lot cheaper. By using a persistent connect Netlfix can reduce overall device requests, improve device performance, understand and debug the customer experience better, enable more real-time user experience innovations, and reduce overall cloud costs by replacing “chatty” device protocols today (which account for a significant portion of API traffic) with push notifications. Operations did take a hit. Sync systems are much easier to understand and debug. Also, making the migration was not easy. Changing sync code to async is not for the faint-hearted.
- This is hilarious. Read the whole thread. You won't be disappointed. @stef: You are in a startup. All around is a burning runway. There are exits to the North and East. You have a bootstrap. There is a VC here.
