Links of the day 20 - 10 - 2014

Today's links 20/10/2014 : Deep learning, Distributed System Model Checking, Man in the middle SSL attack, Buffer Bloat Benchmark

• Stanford Unsupervised Feature Learning and Deep Learning Tutorial : everything is in the title :) 
• TLA : Domain specific language for verifying complex and concurrent system by Leslie Lamport.  
• SSLsplit : tool for man-in-the-middle attacks against SSL/TLS encrypted network connections. 
• RRUL test suite : buffer bloat benchmark suit for analyzing network performance under the heavy workloads that typically induce bufferbloat and other networking problems.

Links of the day 15 - 10 - 2014

Today's links 15/10/2014: Resiliency , CEPH , storage, RDMA, NVM

• Billion-Way Resiliency Project : what is interesting to see is as we move more and more toward hyper scale system, previously dismissed DRAM error becomes a predominant challenge 
• CEPH days : [slides] 
• High performance Ceph with RDMA : leverage Mellanox Accelio to deliver RDMA transport layer. 
• Persistent memory programming (pmem): NVM Library builds on the Direct Access (DAX - note: not yet in upstream kernel) 

Links of the day 14 - 10 - 2014

Today's links 14/10/2014: Amazon monopoly question, Cloud, Velocity conf, OSv - CloudOS

• It's not my Problem I'm renting them : Very good introduction to cloud. And also how cloud shield you from low level issue, ex: what about SSD wear issue - don't care i m renting them.  Scott Hanselman: "Virtual Machines, JavaScript and Assembler" Keynote - Velocity Santa Clara 2014 
• Velocity conference : All videos of the excellent velocity conference.
• Amazon Is Not a Monopoly vs Amazon Must Be Stopped : Compelling argument on both side but both completely ignore Amazon AWS and cloud strategy which implies they probably misunderstood a large portion of Amazon model. 
• OSv : Optimizing the Operating System for Virtual machines using OSv cloud OS -  Usenix 2014

Links of the day 10 - 10 - 2014

Today's links 10/10/2014: #MachineLearning, #BigData, Distributed Computation

• Recommender Problem : Under the hood of Netflix , recommendation system. Apparenty they  spend more than 150 M$ on their recommendation system. [slides]
• ONYX : a cloud scale, fault tolerant, distributed computation system written in Clojure, for Clojure
• Understanding Random Forests: good introduction on how to start from a set of measurements, learn a model to predict and understand a phenomenon

Links of the day 09 - 10 - 2014

Today's links 09/10/2014: Scaling machine learning, bitcoin and bribes

• Parameter Server : The parameter server makes it easy to scale machine learning algorithms by separating the problems of processing data and the problem of communicating and synchronizing them between different machines.[usenix paper] 
• Bribes and Bitcoin : How to accept bribes with bitcoin and why country with high corruption index embrace faster than others.

Links of the day 08 - 10 - 2014

Today's links 08/10/2014: Power 8 , NUMA, VM flash cloning , state of bitcoin

• Project Fargo / VMfork : flash cloning solution from VMWare, allow the very fast cloning of VM ( second vs minutes). VMware needs to push that if it wants to keep its hypervisor relevant compared to docker. 
• IBM Power 8 server : Impressive beast with proprietary NUMA interconnect enabling to reach up to 192 core and 16 TB of RAM by linking 4 nodes together. 
• State of Bitcoin Q3 2014 : adoption , usage, ATMs, investment is up but market cap is down ( probably due to the recent massive sell off ) 

Links of the day 07 - 10 - 2014

Today's links 07/10/2014: #bigdata , RDMA, InMemory everything, Log,  #Openstack Storage , unreliable network coding

• ADMS 2014 : Workshop on Accelerating Data Management Systems Using Modern Processor and Storage Architectures
• Accelerating Data Management and Processing on Modern Clusters with RDMA-Enabled Interconnects : how to leverage RDMA for current and next gen data processing cluster. 
• Oracle's In-Memory Data Management Strategy: In-Memory in all Tiers, and for all Workloads : Big push to move to an all memory approach from Oracle. Not sure that all the piece of the puzzle is already in place to support such vision.
• I heart Log : very nice and well written short books on log ( not just system log )
• Network Coding in unreliable environment [Paper 1] and [paper 2] from MIT
• Evaluation of Openstack storage options : Good overview of the state of Openstack storage. Give a good idea of the trade off in term of performance, complexity, cost , etc..
