Netw0rk-King: October 2008
http://netw0rk-king.blogspot.com/2008_10_01_archive.html
Thursday, October 30, 2008. Looking Up Data in P2P Systems. They make a largely unfounded claim that P2P systems are useful for a lot more than illegal music sharing. However, for the most part, P2P systems haven't seen widespread adoption for problems other than illegal file sharing (you nerds in the back of the room are quick to point out that bit torrent is used to distribute various flavors of linux, but that was an already solved problem, sit back down). Why? Tuesday, October 28, 2008. ANTS is a net...

Netw0rk-King: PNUTs, SCADS, Hive
http://netw0rk-king.blogspot.com/2009/02/pnuts-scads-hive.html
Wednesday, February 25, 2009. PNUTs, SCADS, Hive. Notes on Tyson's presentation about PNUTS:. Complaint: not enough control over replication. Predicate to system, apply to the system before. Hash or sorted tables. No foreign key constraints (not normalized? Selection predicates, and projection from tables. Per record timeline consistency, all replicas apply updates to record in same order. all updates go to a master, which moves around for performace. No fine control over replication factor.

Netw0rk-King: August 2008
http://netw0rk-king.blogspot.com/2008_08_01_archive.html
Saturday, August 30, 2008. The Design Philosophy of the DARPA Internet Protocols (Clark, MIT). Briefly summarize the paper (1-2 short paragraphs). A reflection on the birth of the the network and transport layers of the TCP/IP model protocol stack. Over 15 years countless individuals contributed to the development of a network stack that could support continued growth of the ARPANET. Their design was inspired by 7 goals:. Robustness (it was a military project after all, network gateways might be bombed).

Netw0rk-King: Azure, Google Apps Security, AWS
http://netw0rk-king.blogspot.com/2009/03/azure-google-apps-security-aws.html
Friday, March 27, 2009. Azure, Google Apps Security, AWS. Takes us to a list of white papers that have been written about the up coming Azure cloud service, the second link points us to the the most helpful of these white papers, called Introducing the Azure Services Platform. The components of the MS cloud software stack are:. Still vague, but will probably be a virtual machine management layer similar to that provided by Amazon's EC2 service. Access control, service management, application integration.

Friday, March 27, 2009. DTrace, XTrace, Friday. DTrace: Dynamic Instrumentation of Production Systems. DTrace is a tracing tool with the following features:. Entirely dynamic, has zero cost when not turned on. Centralized, one stop shop for all kernel and user level tracing. Built into Solaris, and subsequently other systems. Guarantees no silent trace data corruption. Arbitrary actions can be used to enable probes. Predicates (filtering) at the source. What is the problem? Is the problem real? They adhe...

Netw0rk-King: January 2009
http://netw0rk-king.blogspot.com/2009_01_01_archive.html
Thursday, January 29, 2009. Failure Trends in a Large Disk Drive Population. Summary of the paper. This seems like something we could (and probably should) reproduce in chukwa. Also, we definitely should have cited this paper in the Chukwa CCA paper. They collect the following metrics about disks into Bigtable (which is on top of GFS), and then analyze it using Sawzall:. Environmental factors (such as temperatures). The Self-Monitoring Analysis and Reporting Technology (SMART) parameters. In a word, usef...

Friday, March 27, 2009. Artemis, Scribe, Chukwa. An open source project created at Facebook, this system shines in its simplicity (collect logs) and its effective reuse of the lower level Thrift RPC project. Once logs are collected, they can be queried in an ad-hoc fashion using Hive. Subscribe to: Post Comments (Atom). Ion's 294 Cloud Computing Webpage. Other CS294 Students' Blogs.

Netw0rk-King: September 2008
http://netw0rk-king.blogspot.com/2008_09_01_archive.html
Monday, September 29, 2008. Solving problems in the early days of wireless. Is it weird that this paper. From '94 feels like ancient CS history? Maybe it is just in my head, but reading any paper from PARC causes me to assume the paper is likely old and likely influential. This paper picked up where Phil Karn. Left off with MACA which was "just an idea" that Karn had introduced to handle the hidden terminal scenario. More effectively than CSMA. Carrier Sense Multiple Access). They also address the proble...
