Hey, it's HighScalability time:

This is an ultrasound powered brain implant! (65nm GP CMOS technology, high speed, low power (100 µW))

• 70: percentage of the worlds transactions processed using COBOL.  
• Quotable Quotes:
  • John Siracusa: Apple has shown that it wants to succeed more than it fears being seen as a follower.
  • @Dries: "99% of Warren Buffett's wealth was built after his 50th birthday."
  • @Pinboard: It is insane to run a bookmarking site on AWS at any kind of scale. Unless you are competing with me, in which case it’s a great idea—do it!
  • @dvellante: I sound like a broken record but AWS has the scale to make infrastructure outsourcing marginal costs track SW curve 
  • @BrentO: LOL RT @SQLPerfTips: "guess which problem you are more likely to have - needing joins, or scaling beyond facebook?"
  • @astorrs: Legacy systems? Yes they're still relevant. ~20x the number of transactions as Google searches @IBM #DOES14 
  • @SoberBuildEng: "It was all the Agile guys' fault at the beginning.Y'know, if the toilet overflowed, it was 'What, are those Agile guys in there?!'" #DOES14
  • @cshl1: #DOES14  @netflix "$1.8M revenue / employee" << folks, this is an amazing number
  • Isaac Asimov: Probably more inhibiting than anything else is a feeling of responsibility. The great ideas of the ages have come from people who weren’t paid to have great ideas, but were paid to be teachers or patent clerks or petty officials, or were not paid at all. The great ideas came as side issues.


• With Fabric can Twitter mend the broken threads of developer trust? A good start would be removing 3rd party client user limit caps. Not sure a kit of many colors will do it.


• Not only do I wish I had said this, I wish I had even almost thought it. tjradcliffe: I distinguish between two types of puzzles: human-made (which I call puzzles) and everything else (which I call problems.) In those terms, I hate puzzles and love problems. Puzzles are contrived by humans and are generally as much psychology problems as anything else. They basically require you to think like the human who created them, and they have bizarre and arbitrary constraints that are totally unlike the real world, where, as Feyrabend told us, "Anything goes."


• David Rosenthal with a great look at Facebook's Warm Storage: 9 [BLOB] types have dropped by 2 orders of magnitude within 8 months...the vast majority of the BLOBs generate I/O rates at least 2 orders of magnitude less than recently generated BLOBs...Within a data center it uses erasure coding...Between data centers it uses XOR coding...When fully deployed, this will save 87PB of storage...heterogeneity as a way of avoiding correlated failures.


• Gene Tene on is it a CPU bound future: I don't think CPU speed is a problem. The CPUs and main RAM channels are still (by far) the highest performing parts of our systems. For example, yes, you can move ~10-20Gbps over various links today (wired or wifi, "disk" (ssd) or network), but a single Xeon chip today can sustain well over 10x that bandwidth in random access to DRAM. A single chip has more than enough CPU bandwidth to stream through that data, too. E.g. a single current Haswell core can move more than that 10-20Gbps in/out of it's cache levels. and even relatively low end chips (e.g. laptops) will have 4 or more of these cores on a single chip these days. < BTW, a great thread if you are interested in latency issues.

Don't miss all that the Internet has to say on Scalability, click below and become eventually consistent with all scalability knowledge (which means this post has many more items to read so please keep on reading)...
