Spectre CPU Vulnerability Online Checker
The most dangerous threat of the recent Spectre Attack(CVE-2017-5753、CVE-2017-5715) for individual users is attacking from web browser to steal your personal accounts and information, such as your emails, dropbox, etc.

This tool can detect whether your browser is vulnerable to Spectre Attack and can be easily exploited.

If the result is VULNERABLE, it is definitely true. However, if the result is NOT VULNERABLE, it doesn't mean your browser is absolutely not vulnerable because there might be other unknown attacking methods.

This tool is still in developing, stay tuned...

citerus/dddsample-core: This is the new home of the original DDD Sample app (previously hosted at sf.net)..
This is the new home of the original DDD Sample app hosted at SourceForge.

Our intention is to move everything from SourceForge to GitHub in due time while starting upgrading both the technical aspects as well as the DDD aspects of the DDD Sample.

The application uses Spring Boot. To start it go to the root directory and type mvn spring-boot:run or run the main method of the Application class from your IDE.

Discussion group: https://groups.google.com/forum/#!forum/dddsample

Development blog: https://citerus.github.io/dddsample-core/

Call a function in a shared library - Rosetta Code
Show how to call a function in a shared library (without dynamically linking to it at compile-time). In particular, show how to call the shared library function if the library is available, otherwise use an internal equivalent function.

CryptoKitties is a blockchain project built in Ethereum

Each CryptoKitty has a 256-bit genome and is breedable with other kitties via smart contract. Certain physical characteristics that can only be unlocked through breeding; there are a nigh-unlimited number of possible combinations.

A fixed number of “Gen 0” kitties that will be released in late November. Future CryptoKitties (e.g. Gen 1, Gen 2, etc.) can only be created by breeding efforts from the community.

GitHub - jamesob/tinychain: A pocket-sized implementation of Bitcoin
This is an attempt by me to make a font that is just a box with the unicode code point inside. These are usually not in a font but rather programmatically generated by programs as they encounter characters that have no associated glyph.

Google Codelabs
Google Developers Codelabs provide a guided, tutorial, hands-on coding experience. Most codelabs will step you through the process of building a small application, or adding a new feature to an existing application. They cover a wide range of topics such as Android Wear, Google Compute Engine, Project Tango, and Google APIs on iOS.

A Neural Network Playground
This was created by Daniel Smilkov and Shan Carter. This is a continuation of many people’s previous work — most notably Andrej Karpathy’s convnet.js and Chris Olah’s articles about neural networks. Many thanks also to D. Sculley for help with the original idea and to Fernanda Viégas and Martin Wattenberg and the rest of the Big Picture and Google Brain teams for feedback and guidance.

Let's code a TCP/IP stack, 1: Ethernet & ARP
Writing your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact1 - the important parts being TCP header parsing, the state machine, congestion control and retransmission timeout computation. The most common layer 2 and layer 3 protocols, Ethernet and IP respectively, pale in comparison to TCP’s complexity. In this blog series, we will implement a minimal userspace TCP/IP stack for Linux. The purpose of these posts and the resulting software is purely educational - to learn network and system programming at a deeper level.
