所以我认为同学们不要妄自菲薄，见到自己不懂的，或似懂非懂的，就认为是高深学问，畏而敬之。更不要骗自己，不懂却认为是懂。同学要问︰皇帝何来新衣了？不久前一位同学问及他高举的诺斯的某术语何解。我说不懂。我怎会不懂诺斯呢？同事十三年，好几个学期他旁听我的课。诺斯对问题重要性的感受好，这是天赋，是他的本钱，创造术语只不过是他的成名玩意，而这种颇为流行的玩意他的本领只是一般。是的，经济学行内有走不同路线的人，本领各各不同，有些成名，有些被认为是笨蛋。同学不要管这些。要管的是分析，因为这是脑子的操练，对整生的任何一方面都有好处。论分析，其中一个要点是任何术语，甚至任何一个字，其意思或理解都不要放过。坚持要知道，要明白。这样，三几年后同学会体会到学问有真假之分。是的，做学问要执着。 -

/weblog/design/distribute
There are two key primary ways of scaling web applications which is in practice today.
1) “Vertical Scalability” - Adding resource within the same logical unit to increase capacity. An example of this would be to add CPUs to an existing server, or expanding storage by adding hard drive on an existing RAID/SAN storage.
2) “Horizontal Scalability” - Adding multiple logical units of resources and making them work as a single unit. Most clustering solutions, distributed file systems, load-balancers help you with horizontal scalability.
Scalability can be further sub-classified based on the “scalability factor”.
1) If the scalability factor stays constant as you scale. This is called “linear scalability“.
2) But chances are that some components may not scale as well as others. A scalability factor below 1.0 is called “sub-linear scalability“.
3) Though rare, its possible to get better performance (scalability factor) just by adding more components (i/o across multiple disk spindles in a RAID gets better with more spindles). This is called “supra-linear scalability“.
4) If the application is not designed for scalability, its possible that things can actually get worse as it scales. This is called “negative scalability“.

* The Golden Hammer. Forcing a particular technology to work in ways it was not intended is sometimes counter-productive. Using a database to store key-value pairs is one example. Another example is using threads to program for concurrency.
* Resource Abuse. Manage the availability of shared resources because when they fail, by definition, their failure is experienced pervasively rather than in isolation. For example, connection management to the database through a thread pool.
* Big Ball of Mud. Failure to manage dependencies inhibits agility and scalability.
* Everything or Something. In both code and application dependency management, the worst practice is not understanding the relationships and formulating a model to facilitate their management. Failure to enforce diligent control is a contributing scalability inhibiter.
* Forgetting to check the time. To properly scale a system it is imperative to manage the time alloted for requests to be handled.
* Hero Pattern. One popular solution to the operation issue is a Hero who can and often will manage the bulk of the operational needs. For a large system of many components this approach does not scale, yet it is one of the most frequently-deployed solutions.
* Not automating. A system too dependent on human intervention, frequently the result of having a Hero, is dangerously exposed to issues of reproducibility and hit-by-a-bus syndrome.
* Monitoring. Monitoring, like testing, is often one of the first items sacrificed when time is tight.

http://highscalability.com[..]e-scalability-lessons-in-30-minutes.html If we are seeing a sustained arrival rate of requests, greater than our system is capable of processing, then something has to give. Having the entire system degrade is not the ideal service we want to give our customers. A better approach would be to process transactions at our systems maximum possible throughput rate, while maintaining a good response time, and rejecting requests above this arrival rate. -
