Today's links 01/04/2015: Messaging, WS #Tor Routing, #Bitcoin time stamping, HPC programming model

Exactly once messaging : more rant on the subject, basically guarantee anything , especially message behavior is hard. Its even harder without formal proof and most system out there do not have any.
Hammer Protocol : an implementation of Tor Routing for Web Services
Decentralized Trusted Timestamping using the Crypto Currency Bitcoin : interesting, however it beg the question, how do you garantee that the timestamp generated in the first place is accurate. Unless the time at each peer signing it is accurate we can have huge variation.
High-Performance and Scalable Designs of Programming Models for Exascale Systems :focus on programming models and their designs for upcoming exascale systems with millions of processors and accelerators such as current status and future trends of MPI and PGAS (UPC and OpenSHMEM) programming models.

Today's links 22/01/2015: NUMA & VMs,#openstack & messaging, continuous deliver

Estimating memory locality for virtual machines on NUMA systems : using sampling techniques to
Scaling openstack - messaging : scaling is hard , especially when your messaging stack is already showing sign of weakness.
Continuous Delivery at Scale: how CD evolve at Linkedin

Today's links 25/11/2014: #AWS reinvent video , Opensource #CPU, messaging.

AWS Re:Invent video : 215 videos of 2014 Amazon event.
Open Source Parallel CPU : feel deja vu with some hints of connection machine
Kayos : fast, low cost, fault tolerant messaging and durable queueing system that offers predictable performance and can take advantage of high end dedicated hardware as well as unreliable, commodity infrastructure like EC2.... Wow , even if they achieve just half of that it would be great :)

Today's links 20/11/2014: tracing, messaging, queue, cache is the new ram

Tracing summit : Tracing Summit 2014 held in Düsseldorf, Germany, on October 13, 2014, video are also available here
Operating Apache Samza at Scale : how do leverage samza under kafka to scale your messaging infrastructure.
Cache is the new ram : with the rise of in memory database CPU cache becomes the next frontier ( but what's next ? cpu register is the new cache ?? )
Queues Don't Fix Overload : on why queue are great but not the silver bullet and what are their limitation.

Today : Web Business Models, Management, HP universal memory to rule them all ( my precious ...) and network reliability.

Web and Mobile Business models :List of Internet - Web business models. It give a very good and quick view of the different business model in the start-up web-sphere. Note here is the original list from AVC
How to Ruin Your Company with One Bad Process : how forgetting personal interest and company politics can ruin a perfect plan.
Iris Decentralized Cloud Messaging : a reasonable compromise between the decentralized nature of the brokerless systems and the minimal-configuration and management of the brokered ones. Iris lends itself to building large-scale systems the way we conceptualize and reason about them—by using services as the building blocks, not instances.
The Network is Reliable - An informal survey of real-world communications failures : Very good list and examples of real world network failure but no surprise the if you want a reliable network or tolerate partition you have to invest the effort , time and money to make it so.. Not magic there.. And even so you are not protected from murphy's law.
The End of a Necessary Evil: Collapsing the Memory Hierarchy : HP's CTO post/ talk on their big push toward Universal memory, kind of like one memory to rules them all and in HP bind them.

Ramcloud, High performance Messaging, Bitcoin and probabilistic programming and Thesis DB and Microservices, CockroachDB.

LMAX Disruptor : A High Performance Inter-Thread Messaging Library. Nothing really knew under the sun, Ring buffers perform better than queues .. But still worth a look and use
Bitcoin the Stripe perspective : Stripe advocate the use of bitcoin as universal currency between foreign exchange market and financial systems
StackOverflow Update: 560M Pageviews A Month, 25 Servers, this show that the Microsoft stack can perform very well as its 100% C# .
Why Probabilistic Programming Matters : Interesting view on probabilistic programming: can facilitate M2M interaction via adaptive data interpretation.
Streaming File Synchronization : How Dropbox implemented and delivered file synchronization
Open Access Theses and Dissertations : 1000+ sources, indexes 2,184,743+ theses and dissertations. If you are looking up a thesis or detailed information in a special field you probably find it there.
Memory and object management in RAMCloud : log structured management of memory allow to achieve 80-90% memory utilisation while still offering high performance
Master's Thesis: On Dependability Modeling in a Deployed Microservice Architecture : look into the dependability of microservices used in the Soundcloud architecture
CockroachDB : A Scalable, Geo-Replicated, Transactional Datastore, No atomic lock :) . By some of the guys that build Spanner at Google. It use the Raft consensus protocol from Ramcloud to maintain cooherent and consistent range information across nodes.
