This document compares performance of Node.js, Apache + PHP, Manhattan, and Mojito frameworks. Node.js showed superior performance scaling to over 3,000 requests per second with low latency. Manhattan and Mojito also outperformed Apache + PHP in some tests. The document concludes Node.js is well-suited for I/O bound use cases that require handling many concurrent requests quickly and reliably.
A Review on Privacy Preservation in Data Miningijujournal
The main focus of privacy preserving data publishing was to enhance traditional data mining techniques
for masking sensitive information through data modification. The major issues were how to modify the data
and how to recover the data mining result from the altered data. The reports were often tightly coupled
with the data mining algorithms under consideration. Privacy preserving data publishing focuses on
techniques for publishing data, not techniques for data mining. In case, it is expected that standard data
mining techniques are applied on the published data. Anonymization of the data is done by hiding the
identity of record owners, whereas privacy preserving data mining seeks to directly belie the sensitive data.
This survey carries out the various privacy preservation techniques and algorithms.
An overview of emerging trends in construction technologiessabnisajit
Awareness in respect of Emerging Trends in Construction technology play a vital role in mitigating impacts of built environment on natural environment. Use of alternative materials and technologies impel towards sustainable development. This is an effort to bridge the gap between Industry and academia.
ScottMadden has developed an approach for analyzing data center requirements and driving improvements in existing data center retrofits. Our approach takes into account the technological requirements, the physical attributes of a data center, and the requirements for a rigorous measurement and verification program needed to ensure improvements actually capture the energy efficiently gains and the resultant greenhouse gas reductions.
Our approach addresses the latest trends in data center management such as virtualization and cloud computing and provide a framework for developing metrics needed to drive changes in data center performance.

When developing data center energy-use estimations, engineers must account for all sources of energy use in the facility. Most energy consumption is obvious: computers, cooling plant and related equipment, lighting, and other miscellaneous electrical loads. Designing efficient and effective data centers is a top priority for consulting engineers. Cooling is a large portion of data center energy use, second only to the IT load. Although there are several options to help maximize HVAC efficiency and minimize energy consumption, data centers come in many shapes, sizes, and configurations. By developing a deep understanding of their client’s data center HVAC requirements, consulting engineers can help maintain the necessary availability level of mission critical applications while reducing energy consumption.
Pyrolysis is the heating of an organic material, such as biomass, in the absence of oxygen. Biomass pyrolysis is usually conducted at or above 500 °C, providing enough heat to deconstruct the strong bio-polymers mentioned above

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

8. Event Queue
• does only one thing at a time
• events that occur are queued for
processing
• after an event was processed the next one
is fetched from the queue
9. The difference
Workers Event Queue
1. synchronous call 1. asynchronous call that
specifies event(s) that can
2. worker blocked occur (callback)
3. periodically check if 2. process next event
worker can go ahead
3. specified event occurs and
4. call returns is put on the queue
5. worker goes ahead on 4. process goes ahead
next check
10. Another difference
Workers Event Queue
• 1 connection per • N connections per
worker process
• N workers per CPU • 1 process (per CPU)
11. Regarding...
• static file serving benchmarks
• are not relevant, unless you plan to do
heavy duty static file serving (I’m not)
• hello world benchmarks
• still ignore most of what matters, e.g.
accessing a database or other back-ends
12. Realistic
Real World Benchmark
• a lot of variables that have to be controlled
• more complex, likely to surface weird bugs
• face unanswerable questions
• are expensive to do
• are easy to attack, but hard to defend
13. My Reasoning
• “I can not compare everything out there
against everything else. But I can compare
what I want to use in the future against what
I am using today.”
14. Search Case Study
• Right Panel retrieved using AJAX
• { ‘html’: ‘<div>...</div>’, ‘css’: ‘...’, ‘js:’ ‘...’, ... }
15. Refresh Right Panel
1. receive a request JSON API
2. call a JSON API over HTTP 2.
3. manipulate the data structure Node.js 3.
4.
4. render it as HTML using Mustache 1. 5.
5. write back wrapped in JSON Client

19. Apache + PHP
• works, in production for decades
• initial response times are “good enough”
• scales, but you need $$$
• baseline to get a feeling for the numbers
21. Node.js (+ YUI)
• works, but very new and untested stack
• initial response times are very low
• scales extremely well
• YUI works well, but still has pitfalls
22. Node.js Fun Facts
• >3100 requests per second
• 100k requests in 32s
• 9MByte/s network traffic
• serve >2k req/s at 20ms average latency
• 99% @ 47ms
28. Manhattan + Mojito
• works, but extremely new and untested
stack
• initial response times are low (60%
compared to Apache/PHP)
• scales well (twice as good as Apache/PHP)
31. Findings
• Both node.js implementations scale linearly
before CPU usage hits 100%
• Node.js scales extremely well as proxy
• Manhattan and Mojito can perform better
than Apache and PHP (for this use case)
• Node.js applications are very sensitive to
memory leaks or complex/blocking code
32. DNS in Node.js
• getaddrinfo() sys call is synchronous
• gethostbyname() is, too
• ares_gethostbyname() is asynchronous
• no cache
• node 0.6 uses a getaddrinfo() thread pool,
but still relies on ares for other calls
34. Manhattan?
• Yahoo!’s Node.js cloud
• can run any node.js application
• allows calls to HTTP APIs (e.g.YQL)
• deployment of versioned apps
• apps can specify their environment
http://developer.yahoo.com/blogs/ydn/posts/2011/11/yahoo-announces-cocktails-%E2%80%93-shaken-not-stirred/
35. Mojito?
• Yahoo!‘s Node.js MVC framework
• provides identical similar runtime for your
code on the client and server
• contains all server- and client-side code
• built on top of YUI
• will be open sourced
http://developer.yahoo.com/blogs/ydn/posts/2011/11/yahoo-announces-cocktails-%E2%80%93-shaken-not-stirred/
36. The Cocktails way
Mojito Application
Mojit
Assets
Model Client JS Images
Controller
View CSS ...
37. Conclusion
• Node.js can serve hundreds of concurrent
requests quickly and reliable, “better” than
Apache/PHP
• It scales extremely well for I/O bound use
cases
• It tears down the client-server language
barrier, opening new architectural
possibilities
