This document provides guidance on developing a connected device solution for a coffee cup called the Connected Cup using WSO2 IoT Server. It describes developing a device agent to display data on the cup, device APIs for communication, UI extensions, analytics processing, a device plugin, and a Carbon feature. Code samples and links are provided for each aspect including getting started with the Connected Cup sample.
The document discusses Android application (APK) security and obfuscation. It notes that over 50% of Android phones can be rooted. It then discusses vulnerabilities that can allow access to app data, such as logins, credit cards, and API keys. It provides recommendations for improving app security through obfuscation techniques like using ProGuard, DexGuard, encryption, tamper detection and emulation detection. It also discusses decompiling apps and tools for working with Android bytecode.
This document provides an overview of common web vulnerabilities and techniques for exploiting them using a vulnerable web application called DVWA (Damn Vulnerable Web Application). It discusses low-level vulnerabilities like brute force attacks, command injection, CSRF, file inclusion and SQL injection. It then goes into more detail on different SQL injection techniques like concatenation, error-based detection, union queries, retrieving data from tables. It also covers blind SQL injection, file uploads, and both reflected and stored cross-site scripting vulnerabilities. The document appears to be an introduction or guide to using DVWA to learn about hacking web applications.
This document provides an overview of startup best practices including lean startup methodology, user stories, agile development practices, Git version control, metrics and analytics, and customer acquisition and retention strategies. It emphasizes frequent iteration and customer feedback to build the minimum viable product and validate business assumptions quickly.
This document discusses making Linux capable of hard real-time performance. It begins by defining hard and soft real-time systems and explaining that real-time does not necessarily mean fast but rather determinism. It then covers general concepts around real-time performance in Linux like preemption, interrupts, context switching, and scheduling. Specific features in Linux like RT-Preempt, priority inheritance, and threaded interrupts that improve real-time capabilities are also summarized.
(1) This document provides a quick tour of machine learning concepts including the components, types, and step-by-step process of machine learning.
(2) It discusses machine learning applications in areas like credit approval, education, recommender systems, and reinforcement learning.
(3) The tour outlines the key components of a machine learning problem including the target function, training data, learning algorithm, hypothesis set, and learned hypothesis. It also distinguishes between supervised, unsupervised, and semi-supervised learning problems.

177. 承襲Ruby特色
if(foo){
a = bar;
}
a = bar if foo
var name = “JSON”
var msg = “hello”
var foo = name + “ say ” + msg
也更於易讀
name = “JSON”
msg = “hello”
foo = “#{name} say #{msg}”
