Stuff The Internet Says On Scalability For December 23, 2011

A merry HighScalability to all and to all a good night:

• Santa: 3.7 million appointments; iPad2 == 1986 Cray 2 6 processor super computer; Watson: 200 million pages of natural language content 
• Funny: a cautionary tale about storage and backup. Where is my data? I’m kinda big deal after all! I should have listened to my postdoc, he can build cheaper storage than you can.
• Nothing stirs up more energy than when someone says they are abandoning and old beloved framework for a newer sexier model. Feelings of betrayal and abandonment leak over everything, which is always a good draw for reality social networking. Here Paul Querna tells why The Switch: Python to Node.js. And here we see the response on Hacker News. Python got the job done for cloudkick, they were acquired, but they wanted something more going forward, a trophy wife if you will, after the first wife put them through law school. Good discussion all around. You may find something that helps in your own platform decision. Or you just may find it entertaining.

Stuff The Internet Says On Scalability For December 16, 2011

A HighScalability is forever:

• eBay: tens of millions of lines of code; Google code base change rate per month: 50%; Apple: 100 million downloads, Internet: 186 Gbps
• Quotable quotes:
  • @OttmarAmann : Scalability is not as important as managing complexity 
  • @amankapur91 : Does scalability imply standardization, and then does standardization imply loss of innovation?
• Why wireless mesh networks won’t save us from censorship. Shaddi Hasan harshes the buzz on the utopian vision of a darknet freeing us from a SOPA/RIAA/everything tyranny. The reasons: Management is hard and expensive; Omni-directional antennas suck; Single-radio equipment doesn’t work; multi-radio equipment is very expensive; Your RF tricks won’t help you here; Unplanned mesh networks break routing. My take: what can't be routed around must be crushed.

Stuff The Internet Says On Scalability For December 9, 2011

It takes a licking and keeps on HighScalabilitying:

• Instagram: 60 photos per second; Twitter: 8,868 Tweets per second MTV Awards; Foursquare: 15 million users; Facebook: 60 million qps; Netflix: stream 1 billion hours in Q4; Evolution: 16,000 eyes; Evernote: 750K Paid Users; AOL: 60,000 Servers;  Netflix API: 20,000 requests per second; Tumblr: 900 posts per second.

  • @pavlobaron : @old_sound if this site isn't on highscalability.com , I won't open it
  • @nzmrmn : Words I hate: moist, "sinfully decadent," facilitator, dopesauce, deliverables, accountability, coolio, "ping me," scalability.
  • @anggriawan : Mark Callaghan (Facebook Engineer): "You can tune #MySQL to perform very fast per node if you know what you’re doing."
  • Jesper Nordenberg : Java is good at hiding the real complexities of programming and introducing incidental ones.
  •  @markimbriaco : It's true, I'm a hardware nerd. I love servers, not gonna lie.  
    • I see a lot of people comming out of the server closet these days (Kyle Brandt). Be proud!
• Possibly NSFW Cartoon: The Hard Life of a NoSQL Coder
• Making the Netflix API More Resilient. The video must flow. Ben Schmaus explains how Netflix keeps the landsraad supplied even through collapse and revolution: graceful fallback driven by real-time stats and visibility through a dashboard.
• IBM’s 3 big chip breakthroughs explained: Racetrack memory - electrons round a wire like a car goes around a racetrack; Graphene - carbon-based chips; Carbon nanotubes - first transistor with channel lengths that are smaller than 10 nanometers.
• One reason instances are rebooted in the cloud: security updates. It can't always be a sexy cascading failure.

Stuff The Internet Says On Scalability For December 5, 2011

It's HighScalability Time!

• Quotable quotes:
  • @jaykreps : Was wondering, How can I turn my boring, cachable, read-only traffic into random writes on mongodb? And lo! link
  • @marshallk : Google runs 100-200 experiments every day on UI, algorithm & product
  • @styggiti : The problem with companies like IBM and Oracle baking NoSQL "scalability" into their products isn't the tech, it's the $$ licensing.
• Blazing fast node.js: 10 performance tips from LinkedIn Mobile. You may have thought that node.js made just everything magically fast, but Shravya Garlapati has some great strategies for going even faster: Avoid synchronous code; Turn off socket pooling;  Don't use Node.js for static assets; Render on the client-side; Use gzip; Go parallel; Go session-free; Use binary modules; Use standard V8 JavaScript instead of client-side libraries; Keep your code small and light.
• Nice thread in NoSQL Databases on HBase and Consistency in CAP. The short summary of the article is that CAP isn't "C, A, or P, choose two," but rather "When P happens, choose A or C."

Sorry, this edition of Stuff the Internet on Scalability has been called on the account of two straight days of whipping, whirling, wind that has left me powerless to complete the post. Service will resume when Mother Nature is nicer. Pardon me while I try and find our roof...

Stuff The Internet Says On Scalability For November 25, 2011

A HighScalability a day keeps the fail whale away.:

• 46 million turkeys eaten at Thanksgiving; Pinterest 421 million pageviews 
• Quotable quotes:
  • @al3xandr3 : scalability demands decoupling
  • @startupandrew : "Yesterday I did some digestive system scalability testing" -- in reference to eating 140 chicken nuggets
  • Peter Wayner : While the crazy dreamers can continue to craft NoSQL data stores, serious people will want to take a look at Oracle's version.
  • @weblearning : Unitil we get scalability - or that wonderful word massification - in education, we will not get value for money
  • Embrace and extend: @conor_omahony : IBM is Baking NoSQL Capabilities into DB2 and Informix. 
  • @GGopman : I look for scalability. That's what turns me on
• Supercomputing: An Industry in Need of a Revolution. Bartosz Milewski wants decently paying, interesting and meaningful jobs for all (supercomputer programmers). Get on that Santa.

Stuff The Internet Says On Scalability For November 18, 2011

Every kiss begins with HighScalability:

• Amazon and the secret to life: 42; 10,240 cores
• Many quatloos worth of quotable quotes:
  • @alesroubicek :  State kills scalability
  • @cincura_net : Wrong. *Shared* state kills scalability.
  • @kpshea : When I think "cloud" computing, I imagine the gaseous Star Trek blob that ate red blood cells (your sensitive data).
  • @kotobuki : I'm interested in scalability of personal fabrication. How to 'scale' in batch production stages will be a key, but still there are barriers.
  • @simonraikallen : The two rules of scalability testing: (1) The bottleneck is always the database (2) You can never predict what the bottleneck will be.
  • @marksbirch : Photo: newyorker: The way we are producing data, we may need a place even bigger than heaven to hold it all…
• Why Stack Exchange Isn’t in the Cloud. It's about love, the love of computers, and what you love you don't let other people own. Also How StackOverflow Scales with SQL Server
• NoSQL No More: Let’s double down with MoreSQL. Alex Tatiyants with an impassioned plea for programmers to throw down these new fangled databases and return to a comfortable and much loved past. To bring this world about Alex wants SQL Everywhere, to spread FUD about NoSQL, and to recognize with enough effort SQL can work for every problem. This brave old vision should bring comfort everywhere to people wearing very small shoes.

Stuff The Internet Says On Scalability For November 11, 2011

You got performance in my scalability! You got scalability in my performance! Two great tastes that taste great together:

• Quotable quotes:
  • @jasoncbooth : Tired of the term #nosql. I would like to coin NRDS (pronounced "nerds"), standing for Non Relational Data Store. 
  • @zenfeed : One lesson I learn about scalability, is that it has a LOT to do with simplicity and consistency.
  • Ray Walters : Quad-core chips in mobile phones is nothing but a marketing snow job
• Flickr:  Real-time Updates on the Cheap for Fun and Profit. How Flickr added real-time push feed on the cheap. Events happen all over Flickr, uploads and updates (around 100/s depending on the time of day), all of them inserting tasks. Implemented with Cache, Tasks, & Queues: PubSubHubbub; Async task system Gearman; use async EVERYWHERE; use Redis Lists for queues; cron to consume events off the queue;

Stuff The Internet Says On Scalability For November 4, 2011

You're in good hands with HighScalability: 

• Netflix - Cassandra, AWS, 288 instances, 3.3 million writes per second.
• Quotable quotes:
  • @bretlowery : "A #DBA walks into a #NoSQL bar, but turns and leaves because he couldn't find a table."
  • @AdanVali : HP to Deploy Memristor Powered SSD Replacement Within 18 Months
  • @eden : Ori Lahav: "When planning scalability, think x100, design x5 and deploy x1.5 of current traffic"
  • @jkalucki : If you are IO bound, start with your checkbook!
• Everything I Ever Learned About JVM Performance Tuning @Twitter. Learn how to tune your Hotspot and other Javasutra secrets.
• By moving off the cloud Mixipanel may have lost their angel status. Why would they do such a thing? Read Why We Moved Off The Cloud for the details. The reason for the fall:  highly variable performance. Highly variable performance is incredibly hard to code or design around (think a server that normally does 300 queries per second with low I/O wait suddenly dropping to 50 queries second at 100% disk utilization for literally hours). It’s solvable, certainly, but with lots of time and money and it’s hard to justify the cost when there’s a better alternative available. On reddit. On Hacker News. Is that a bell I hear?
